The invention provides a controllable mechanical floating-arm-type water hyacinth surrounding device. The controllable mechanical floating-arm-type water hyacinth surrounding device comprises a control system, interception net bodies and mechanical arms, wherein the mechanical arms are installed on bases on the two sides of the front portion of a fishing boat in a hinged manner respectively; the mechanical arms penetrate the centers of the corresponding interception net bodies, and each mechanical arm comprises a first-level arm and a second-level arm; one end of each first-level arm is hinged to the corresponding base through a rotational joint, and the other end of the first-level arm is connected with the corresponding second-level arm through a rotational joint; the tail end of each second-level arm is provided with a rotary harrow which can be driven by a motor to deflect towards the inner side, and the rotational joint between each first-level arm and the corresponding second-level arm and the tail end of each second-level arm are each equipped with a two-way motor propeller; and free moving of the interception net bodies in the water and surrounding of water hyacinth are achieved by controlling the output power and the driving direction of the two-way motor propellers through the control system. By means of the controllable mechanical floating-arm-type water hyacinth surrounding device, rapid surrounding of floating water hyacinth groups can be achieved, and the efficiency of removing operation is improved.

The invention relates to a novel offshore salvaging device for salvaging people fell overboard, and aims to provide a salvaging device which can be flexibly operated by an operator on board and be used for easily salvaging people fell overboard through operation of a control box. In the novel offshore salvaging device, a part between supporting arms and brackets can be folded through a first stretching mechanism; a second stretching mechanism is a hydraulic stretching mechanism; and the stretching mechanisms can be lengthened through a hydraulic system, so that a salvage range can be widened. The novel offshore salvaging device provided by the invention is simple and flexible in structure, and can be applied to an offshore salvage process as a novel mechanism. When people fell overboard cannot save by own, wounded personnel in a semicomatose or comatose state can be saved on board through the salvaging device. The salvage process is safe and the salvage speed is fast; and the influence of an offshore salvage condition is less.

The invention discloses a rotary telescopic water hyacinth salvaging machine with a crushing function. The rotary telescopic water hyacinth salvaging machine comprises a salvaging device and a rotarybase; a slide base is hinged to the rotary base; the salvaging device is connected into the slide base; a crushing assembly is rotatably connected to a tail end of the slide base; and the slide base rotates on the rotary base in a gear transmission mode. The rotary telescopic water hyacinth salvaging machine has the advantages that the machine can be assembled on various boats; the machine can bedriven to work by an engine on a boat body, so that a single conveying boat is changed into a salvaging boat; the rotary base which is controlled by a motor and the telescopic salvaging device are arranged, so that the salvaging device is flexible and diversified, the range of salvaging is expanded; a liftable conveying device and a toothed rotary post are arranged in a conveying shell, so that the phenomenon of clogging is prevented during a salvaging and conveying process of water hyacinth; and the crushing assembly is movably connected to the tail end of the slide base, so that the salvagedwater hyacinth is crushed in time, and subsequent work load is reduced.

The invention relates to a fisher, in particular to a sewage treatment fisher. The technical problem to be solved by the invention is to provide the sewage treatment fisher which can be used for fishing sundries in a large range of sewage and can also be used for fishing small sundries, so that the sewage treatment is cleaner. According to the technical scheme, the sewage treatment fisher comprises a supporting column and the like; an installation column is arranged below the supporting column, first threaded holes are formed in the left side and the right side of the installation column, first screw rods are arranged in the first threaded holes and penetrate through the supporting column, the installation column is connected with the supporting column through the first screw rods, an adjusting mechanism is arranged at the bottom of the installation column, and first screen frames are arranged on the left side and the right side of the adjusting mechanism. By holding the supporting column, sundries on sewage can be fished through the first net frame, the fishing direction of the first net frame can be adjusted to the required direction through the adjusting mechanism to fish the sundries, a net bag does not need to be used, and the fishing range is larger.

The invention discloses a riverway pollution treatment device and treatment method. The riverway pollution treatment device comprises a bottom frame installed on a riverbed, a vertical plate is fixed to the top of the bottom frame, a top plate is fixed to the top of the vertical plate, a salvage box is vertically and slidably installed on the outer wall of the vertical plate, and an open groove is formed in the outer wall, extending out of the water surface, of the fishing box; a long groove is formed in the top of the salvage box, a gear is rotationally installed on the inner wall of the long groove through a rotating shaft, a toothed plate is fixed to the bottom of a top plate located above the gear, a torsional spring arranged on the rotating shaft in a sleeving mode is installed between the gear and the long groove, and a groove is formed in the outer wall of the gear located in the salvage box. And a filter plate is fixed in the groove, and an arc surface block is fixed to the inner bottom of the salvage box. Through cooperation of the structures, the effect of automatically salvaging, filtering and collecting floating garbage in a river channel is achieved, meanwhile, the oxygenation effect on water in the river channel is achieved, the water quality can be improved, and the oxygen enrichment capacity of the water can be improved.

The invention discloses a blue-green algae enrichment salvaging system. The system comprises a salvaging mechanism and an enrichment mechanism, the salvaging mechanism comprises a salvaging platform,an algae taking box is installed on the bottom face of the salvaging platform through a fixing support, an algae water inlet is formed in the algae taking box, an underflow pump is installed in the algae taking box, a driving motor is arranged on the top face of the algae taking box, and a liquid outlet of the underflow pump is connected to a river bank through an algae discharging pipe; and the enrichment mechanism comprises an enrichment platform, a supporting shaft is installed on the enrichment platform, a flow guide impeller is fixed to the supporting shaft, and an enrichment motor is arranged on the enrichment platform. According to the blue-green algae enrichment salvaging system, the enrichment motor controls the flow guide impeller to rotate so as to drive river surface algae water in the coverage range of the flow guide impeller to flow towards the salvaging platform, the salvaging range of the salvaging platform is greatly enlarged, all surrounding river surface algae waterflows towards the salvaging platform, the algae content of the river surface algae water at the salvaging platform is increased, and the salvaging efficiency is greatly improved.

The invention relates to a fishing method for river fishing. Elastic devices are adsorbed to a river wall on a riverside, part of power is provided by high restoring force of elastomers for fishing bya fishing boat, then draft of the boat body is controlled by a ballast tank located at the front part of the boat bottom to complete fishing, and finally, fished floating objects are stored in a rotatable collection wheel through a chute. The fishing method overcomes the defects of complicated structure, difficult operation and the like of the conventional fishing equipment, the collection efficiency is increased greatly, the loading capacity of the fishing boat is increased by the rotatable collection wheel, and back-and-forth unloading time is reduced.
