The invention discloses an automatic cleaning device of a photovoltaic module. The automatic cleaning device comprises rails, a cleaning shaft, a cleaning brush, walking wheels, balance wheels and a motor, wherein two rails are provided, and are symmetrically arranged at the two sides of the photovoltaic module in parallel; the walking wheels and the balance wheels are respectively arranged at the two sides of the cleaning shaft, and are both arranged on the rails; the walking wheels at one side are driven by the motor; the motor drives the cleaning shaft to rotate while driving the walking wheels to walk through a multifunctional shaft; and the cleaning brush is arranged on the cleaning shaft. The automatic cleaning device is simple in structure; the multifunctional shaft is adopted to synchronously drive the cleaning shaft and the walking wheels, so that structural parts of the device are effectively simplified, and a synchronization function is realized; the multifunctional shaft has a self-locking function to effectively stop the slip of the cleaning device caused by inclined installation of the photovoltaic module; and adjusting springs are arranged on the balance wheels for effectively balancing torsional cutting force generated by desynchrony of active walking and passive walking of the balance wheels, so that the walking stability of the device is guaranteed, and the service life of the product is prolonged.

The invention discloses a non-return device for refrigerator compressor performance testing equipment. The non-return device includes a non-return mechanism, a support mechanism connected with the non-return mechanism and supporting the non-return mechanism to limit the rebound of the refrigerator compressor; the non-return mechanism includes The U-shaped seat, the pin shaft passing through the U-shaped seat near the top, and the non-return block rotatably fixed on the U-shaped seat through the pin shaft, the initial height of the non-return block during the rotation process is higher than the U The top of the seat is flat; a torsion spring is embedded between the non-return block and the U-shaped seat; a cushion block is installed near the bottom of the U-shaped seat. The support mechanism includes a mounting frame that is conveniently fixed on the mounting platform and an adjusting frame that is fixedly connected with the mounting frame and can move up and down on the mounting frame; the U-shaped seat is movably fixed on the adjusting frame. The device has the advantages of simple structure, fast adjustment speed, high versatility and low manufacturing cost, and can better realize the accurate positioning requirement of the refrigerator compressor before the power-on performance test.

The invention belongs to a medical apparatus, and in particular relates to an expanded tooth implant, which is characterized by consisting of an implant body (1) and an expanded core (3) and a repair base station (2) matched with the implant body (1), which are mutually embedded by threads. The implant can improve the tightness of the implant in bones, particularly under the condition of loose bones so as to improve the initial stability and reduce the loosening and falling rate, and can also be planted immediately after routine exodontia.

The invention discloses a methanol flowing feeding on-line disinfection method and an automatic control system, which solve the problems of potential safety hazard existence, bacterium contamination, difficult automatic control and the like. Through the arrangement of relevant equipment and steps of residual air pipeline methanol cleaning, steam pipeline disinfection, methanol slag removal, sterilization, automatic flowing feeding and the like, the treatment process is distinct, the pertinence is high, integral structural components for realizing the flow process are simple, various problems caused by automatic methanol flowing feeding in pichia pastoris fermentation are effectively solved, and a high use value is realized.

The invention relates to the technical field of garbage treatment, and discloses a garbage treatment device. The garbage treatment device comprises a control part, a vehicle body and a pretreatment mechanism; the internal of a cylinder is divided into a front cavity and a back cavity through a piston; the side, near the back cavity, of the piston is connected with a piston rod; a free end of the piston rod is connected with an air pipe capable of extending; one end of the air pipe communicates with the front cavity of the cylinder, and the other end of the air pipe penetrates out of the vehicle body to communicate with a sucker; the back edge of the bottom of the vehicle body is hinged with a tipping bucket capable of automatically overturning front and back; the bottom of the vehicle bodyis rotationally connected with a front wheel through a first fixed shaft, and is rotationally connected with a rear wheel through a second fixed shaft; a roller is rotationally connected to the second fixed shaft; multiple blades are peripherally arranged on the outer edge of the roller; the roller is fixedly connected with the rear wheel through an acceleration mechanism; the pretreatment mechanism comprises a lead screw, a nut and a support plate; the lower end of the lead screw is connected with a turntable; and the bottom edge of the turntable is vertically connected with a drill bit. Thegarbage treatment device can collect garbage in ice blocks to prevent falling into a river to flow away.

The invention relates to a beam forming forklift conformal reader antenna and a forklift using the beam forming forklift conformal reader antenna. The beam forming forklift conformal reader antenna comprises a top-layer rectangular metal sheet, a plurality of intermediate-layer metal sheets, a metal plate conforming to the forklift at a bottom layer, and a feed probe; the top-layer rectangular metal sheet and the metal plate are parallel to each other, and the top-layer rectangular metal sheet, the plurality of intermediate-layer metal sheets, and the metal plate surround an air cavity with one side open; a strip through hole is opened on the top the rectangular metal sheet along a longitudinal direction; and the feed probe is arranged at one end of the strip through hole. The invention fully utilizes the advantages of a metal strip through hole antenna, and takes the metal surface of a cigarette logistics forklift as a part of an antenna radiator, so that the antenna has excellent electromagnetic characteristics, and the antenna and the forklift are conformal; therefore, the problem that the antenna beam is uncontrollable and the reading range of the reader is unstable after the conventional reader antenna is mounted on the forklift is solved.
