The present invention provides a novel photovoltaic support structure with a snow removal function for use in a water photovoltaic power station in a cold region of Northeast China, and relates to the technical field of photovoltaic supports, including a float, a bottom beam, an inclined beam, a photovoltaic module and an angle adjustment module. The float is provided with multiple groups, and the multiple groups of floats are arranged in parallel. The bottom beam is fixedly connected between adjacent floats, one end of the inclined beam is hinged to the top of the bottom beam through a first connecting piece, the photovoltaic module is fixedly connected to the top surface of the inclined beam through bolts, and an angle adjustment device is installed between the bottom beam and the inclined beam. Aiming at the problem of snow accumulation on the surface of existing water photovoltaic support modules, the present invention makes partial structural improvements, by adding a support angle adjustment module, when the snow on the surface of the photovoltaic module accumulates to a certain thickness, the angle between the photovoltaic module and the horizontal plane is increased, so that the angle between the photovoltaic module and the horizontal plane reaches 50 degrees, and the snow on the surface of the module can automatically slide down by its own weight, so that the surface of the module is protected from being blocked by snow accumulation, thereby improving the power generation efficiency of the power station.

The present invention discloses a synchronous silent slide rail, comprising a slide rail outer frame, a slide rail middle frame slidably arranged in the slide rail outer frame, a first and a third mid-range points arranged on the slide rail middle frame, the first mid-range point is located at the middle position of the slide rail middle frame, the third mid-range point is located at the front end position of the slide rail middle frame, and an outer frame elastic member is arranged on the slide rail outer frame; when the slide rail middle frame is folded and closed, the third mid-range point abuts against the outer side of the outer frame elastic member, and when the slide rail middle frame is pulled out and opened, the first mid-range point abuts against the inner side of the outer frame elastic member. A gear is rotatably fixed on the frame wall at the rear end position of the slide rail inner frame, and the gear is meshed on the rack. The gear comprises a tooth portion and a connecting portion of an integrated structure, and a synchronous connecting rod can be fixed on the connecting portion to connect with another synchronous silent slide rail. The slide rail of the present invention has good synchronization and obvious noise reduction, simple structure, dual-purpose, and is easy to produce.

This utility model discloses a fuel filler cap, including a fuel filler cap body and a vent valve assembly disposed within the fuel filler cap body and capable of automatically opening and closing to establish an internal and external communication channel. The vent valve assembly includes a valve core, which is subjected to a pre-tightening force to close the internal and external communication channel. The valve core can be controlled to deform, and this deformation overcomes the pre-tightening force and opens the internal and external communication channel. The fuel filler cap of this utility model, with its automatically opening and closing vent valve assembly, can effectively prevent oil emulsification at the fuel filler cap, significantly reducing the probability of false engine diagnostics.

The invention relates to the technical field of textile, and provides a production method of a concave-convex bubble cut pile printing towel and the towel, and the production method comprises the following steps: S1, weaving a blank towel; s2, cutting pile for the first time; s3, pretreatment of the blank towel; s4, pile cutting for the second time; s5, pattern design is carried out, the width of a concave-convex pattern is not smaller than 0.5 cm, the overall area of the concave-convex pattern does not exceed 60% of the overall pattern area, and the concave-convex pattern is a flat coating pattern with 100% of pixel points; s6, size mixing is conducted, specifically, size for the concave-convex pattern comprises concave-convex bubble size, a softening agent and refined oil, and the mass ratio of the concave-convex bubble size to the softening agent to the refined oil is 100: (3-10): (5-8); s7, plate making is conducted according to the pattern design, and a concave-convex plate pattern and a printing plate pattern are printed in sequence; s8, drying is conducted; and S9, ageing, washing and sewing. According to the technical scheme, on the basis of combining rich colors and diversified pattern elements of the printed towel, the concave-convex stereoscopic impression of a jacquard pattern can be simulated, and the appearance effect of combining jacquard and printing can be presented without adopting an embossing mold for pressing.

The utility model discloses a packaging carton compounded with an air bubble film, which comprises packaging side plate surfaces on the front side and the rear side and packaging protection plate surfaces on the left side and the right side, the packaging carton is defined by the packaging protection plate surfaces on the left side and the right side and the packaging side plate surfaces on the front side and the rear side in an integrated structure, and air bubble film surface layers are respectively arranged on the opposite plate surfaces of the packaging protection plate surfaces on the two sides. An air bubble film strip layer is arranged on the side edge of the packaging side plate face, and an L-shaped edge protection part is defined by the air bubble film strip layer and the air bubble film face layer. According to the packaging box assembly, the air bubble film and the carton are compounded to form the packaging box assembly, a plurality of parts are compounded into one part, the working procedure is simple and reliable, and production and assembly are convenient.

The utility model provides a tailing sand gravity coordination pre -homogenization system relates to mine filling technical field. The pre -homogenization system includes storage bin group and mixes hopper. The storage bin group contains at least three parallel warehouses, and each warehouse is equipped with independent feed inlet, bottom double curvature conical discharge port and gate; The curvature radius of the steep section of the discharge port lower part is less than 50% of the curvature radius of the upper gentle slope section, and the included angle between the generatrix of the lower steep section and the horizontal plane is greater than or equal to 75 degrees. The mixing hopper is located below the storage bin group, and the center axes of all discharge ports are located on the distribution circle with the center of the mixing hopper as the center; The inner wall of the mixing hopper is provided with guide plates, each guide plate is inclined downward along the center line and is symmetrical to both sides, and the center line is the highest point, and the inclination angle is 30-35 degrees. When the device works, multiple warehouses discharge synchronously, the material accelerates down through the discharge port, is guided by the guide plate, and is mixed under the action of gravity. The system eliminates time period fluctuation through multiple warehouse storage, realizes external power homogenization by using gravity cooperation and guide plate structure, and effectively prevents arch blockage by double curvature discharge port design. The structure is simple and reliable.
