The invention discloses a charging loop cooling structure. The cooling structure comprises a fixed part and two jack terminals which are hermetically arranged in the fixed part in a penetrating mannerand are used for being connected with cables. Each cable is internally provided with a flow guide pipe used for flowing of a cooling medium. The axial middle of each jack terminal is provided with aslotted hole with an opening in one end. Contact pins connected with the flow guide pipes are arranged in the slotted holes. Through holes communicated with the flow guide pipes are formed in the axial middle portions of the contact pins. Gaps communicated with the through holes are formed between the front ends of the contact pins and the groove holes correspondingly. Flow passing holes communicated with the slotted holes are formed in the opposite sides of the two jack terminals, and flow channels communicated with the two flow passing holes are formed in the fixed part. A first sealing ringis arranged between the corresponding flow guide pipe and the corresponding contact pin, and a second sealing ring is arranged between the rear end of the corresponding contact pin and the corresponding jack terminal. The charging loop cooling structure is good in heat dissipation performance and sealing performance and has the advantages of being simple and compact in structure, safe, reliable and convenient to assemble.

The invention provides a water quality sampling flexibly-jointed locking valve which comprises a water inlet pipe, a water outlet pipe and a ball valve main body connected between the water inlet pipe and the water outlet pipe, a spherical valve core which is arranged in the ball valve main body, and a water sampling plunger valve which is vertically connected with the ball valve main body and arranged between the ball valve main body and the water outlet pipe, wherein a regulating handle is arranged above the ball valve main body, one end of the regulating handle is connected with a ball valve pole which is fixedly connected with the ball valve core, and a sliding locking piece which is mutually and tightly fastened with a locking buckle above the ball valve main body is arranged in the other end of the regulating handle. The water sampling valve adopts a T-shaped connection, a sample can be taken from the splitting cavity of a drainage pipeline and the water sampling can be carried out during a normal water discharging process so as to facilitate the monitoring and processing of the change of the water quality, or the liquid quality of manufacture factories can be dynamically monitored, and the sampling valve is flexibly connected with the nut of a discharge pipe so as to ensure convenient and rapid connection during the equipment maintenance and pipeline change. The regulating handle and the sliding locking piece arranged in the handle ensures that the ball valve core can be conveniently fixed and locked so as to avoid the ball valve closure and ensure safe and reliabledischarge.

The invention discloses an angle-adjustable leaky coaxial cable fixture, and particularly relates to the field of leaky coaxial cable fixtures. The angle-adjustable leaky coaxial cable fixture comprises a fixed seat, wherein the bottom end of the fixed seat is connected with a rotating shaft, the exterior of the rotating shaft is connected with a mounting seat, the outer wall of the mounting seat is connected with a fastening bolt close to the outer side of the rotating shaft, the two ends of the top of the fixed seat are symmetrically connected with a first semicircular ring and a second semicircular ring, protection mechanisms are installed on the inner side walls of the first semicircular ring and the second semicircular ring correspondingly, and a self-locking structure is arranged between the top of the first semicircular ring and the top of the second semicircular ring. According to the invention, cables penetrating through the interior of the fixture can be clasped, a buffering effect can be effectively achieved in the clasping process, self-adaptive clasping treatment is carried out according to the number of the cables in the fixture, the situation that the cables penetrating through the interior shake and are continuously collided, rubbed and damaged with the inner wall of the fixture in the using process is avoided, and the self-locking structure is arranged, so that the operation is easy, and the labor intensity of an operator during mounting and overhauling is reduced.

The invention discloses a cloth rolling device for a chemical cloth fabric. The cloth rolling device for the chemical cloth fabric comprises a bottom plate, wherein a first support is arranged on oneside of the top end of the bottom plate; a second support is arranged on the other side of the top end of the bottom plate; and a fixed rod is arranged on the surface of one side of the second support. The cloth rolling device for the chemical cloth fabric provided by the invention is scientific and reasonable in structure, and safe and convenient to use; through the functions of the bottom plateand a groove, the first support and the second support are conveniently fixed, and the occurrence of the phenomenon that a cloth rolling device with a traditional structure is easy to shake due to instability when being adopted for cloth rolling is avoided; by utilizing the functions of a rotary knob and a lock pillar, a sliding block sliding to the appropriate position can be conveniently lockedand fixed, and the occurrence of the phenomenon that when the number of dye cloths winding on a first rotary shaft is increased and a connecting rod upwards moves through a piston rod, the other end of the connecting rod cannot be fixed is avoided; and through the function of a conveyor belt, the chemical cloth fabric can be conveyed conveniently, so that the occurrence of the phenomenon that thecloth is enabled to pass through a roller shaft by manpower during cloth rolling every time is avoided.

The invention belongs to the field of mining machinery, and discloses a mining machinery lifting self-locking device. The device comprises a base, wherein a mounting groove is arranged in the upper end of the base; a driving motor is fixedly arranged at the left end of the base; an output shaft of the driving motor is fixedly connected to a second two-way lead screw; the output shaft of the driving motor penetrates through the base and is fixedly connected to the second two-way lead screw; the right end of the second two-way lead screw is fixedly connected to a first two-way lead screw througha coupler; the right end of the first two-way lead screw is rotationally connected to the base through a bearing; the first two-way lead screw and the second two-way lead screw are both located in the mounting groove; and two nut blocks are symmetrically arranged on the first two-way lead screw and the second two-way lead screw in a threaded mode. The device is good in lifting adjusting effect, good in self-locking effect, good in protection effect, high in safety and high in practicability.

The invention discloses a soil removing device for agaricus bisporus. The soil removing device comprises a shell, a sealing plate is clamped to the rear side of the shell, and a through groove matchedwith the sealing plate is formed in a rear side plate of the shell; one side of the sealing plate is fixedly provided with an observation window, and a connecting plate is welded to the other side ofthe sealing plate; a conical groove is formed in one side of the connecting plate, a locking mechanism is arranged on the upper side of the connecting plate, the top of an inner cavity of the shell is fixedly provided with a servo motor, one end of a rotating shaft of the servo motor is in transmission connection with a transmission shaft through a coupler, an impeller is fixedly connected to oneend of the transmission shaft, and a movable mechanism is arranged in the shell.
