The invention provides a deicing robot for a four-cracking high-voltage power transmission line. The deicing robot comprises a robot support platform, two six-degree of freedom arms, deicing devices and an intermediate support arm, wherein the two six-degree of freedom arms are arranged at two ends of the robot support platform. By employing the two six-degree of freedom arms and mutual matching of the two deicing devices and the intermediate support arm, the deicing task of a single-phase four-cracking high-voltage power transmission line can be achieved, and the deicing robot is generally applied to a power transmission line of 500Kv; the robot can clear the single-phase four-cracking power transmission line in one time, the deicing robot can cross a four-cracking impedance isolation rod and also can cross a pole tower, and three pole towers which are continuously crossed can be arranged in a straight line and also can be arranged in a broken line; the deicing robot can directly cross the pole tower and is unnecessary to interrupt deicing operation; and the deicing robot is light in weight and relatively small in volume.

The invention relates to a pneumatic conveying nail pressing machine. The pneumatic conveying nail pressing machine comprises a body, a feeding mechanism, a positioning mechanism, a nail pressing part and a pneumatic device, wherein the feeding mechanism, the positioning mechanism, the nail pressing part, the pneumatic device and the body are installed together. A feeding pipe in the feeding mechanism is internally of a T-shaped hollow passageway structure. The positioning mechanism comprises a base, a pressing ring and a cover body, wherein the pressing ring and the cover body are sequentially arranged on the base. The interior of the positioning mechanism is a profiling cavity after the base and the pressing ring are combined, and the cavity is communicated with the T-shaped passageway of the feeding pipe. At least three grooves are evenly distributed in the base in the radial direction of a round hole, and each groove is provided with a spring and a sliding jaw, wherein the spring and the sliding jaw are connected; the head of each sliding jaw is designed into a slope. Nails are conveyed in a pneumatic mode, the positioning mechanism with the special structure is designed, the pneumatic conveying nail pressing machine is especially suitable for nails with large-diameter nail heads and short nail points, the large-diameter nail heads are extruded downwards in the nail pressing process, and the nails are fixed through the design of the sliding jaws, so that the nails are well prevented from being laterally turned over, the work efficiency is improved, and the automation degree and the percent of pass of finished products are increased.

The invention discloses a novel garbage can cover opening structure which comprises a can body and a can cover, the rear side of the can body is provided with a push rod which is driven by a drive device and can move up and down in the vertical direction, and the upper end of the push rod is in pin joint with the rear edge of the can cover; the bottom of the can cover is in pin joint with one or more swing arms, and the lower ends of the swing arms are in pin joint with the interior of the can body or a middleware in the can body; the push rod, the swing arms and the can cover move according to the following relation that when the push rod jacks upwards, the push rod pushes the rear edge of the can cover upward, meanwhile under the constraint of the swing arms, the front end of the can cover moves backwards simultaneously, and a backward cover opening process of the can cover is formed; when the push rod moves downwards, the push rod pulls the rear edge of the can cover downward, meanwhile under the constraint of the swing arms, the front end of the can cover moves forward simultaneously, and finally the cover closing state is formed. The novel garbage can cover opening structure is unique in design structure, the situation that directly upward cover opening of the garbage can is prone to collision with the process of throwing garbage of people is avoided, and the design structure is unique and more humanized.

The invention provides a refrigerating and freezing device, which includes a box body and a magnetic air separation unit. The box body defines a storage space and an air supply duct for delivering cold air flow to the storage space. The first storage container and the second storage container, the first storage container and the second storage container are formed with air inlets, and the magnetic air separation unit is used to connect the air outlet of the air supply duct to the first storage container respectively. The air inlet of the container communicates with the air inlet of the second storage container, and is configured to separate oxygen and nitrogen in the cold air flow to form an oxygen-enriched cold air flow and a nitrogen-enriched cold air flow, and flow the oxygen-enriched cold air flow into the first storage In the container, the nitrogen-enriched cold air flows into the second storage container to form an oxygen-enriched fresh-keeping space in the first storage container, and a nitrogen-enriched fresh-keeping space in the second storage container, which can ensure the quality of the meat It can improve color and reduce nutrient loss, and can also reduce the intensity of aerobic respiration of fruits and vegetables, inhibit the deterioration of fruits and vegetables and reduce nutrient loss.

The invention discloses a method and device for treating volatile organic waste gas. In the method, the volatile organic waste gas firstly enters into a flow rotating and gas distributing system containing a rotating flow tray which is provided with a plurality of cyclone vanes, then the gas which is subdivided by the flow rotating and gas distributing system subsequently enters into a light activation and oxidation system to be irradiated by high power ultraviolet lamps, while radiation-induced decomposition is carried out on part of the waste gas, reactive oxygen is generated to oxidize the organics in the waste gas, after that, the waste gas uniformly passes through a composite material adsorption system to be adsorbed by the high efficiency composite materials, and finally the waste gas is discharged from the waste gas outlet via an explosion-proof fan system. By the method, the efficiency and the rate of treating the volatile organic waste gas are improved, the harm of the waste gas to human health and the environment is weakened, the health of the experimental personnel is further protected and the working environment is improved.
