The present invention is one kind of irregular building block and the wall structure therewith. The irregular building block is a longitudinal shaped material including one top side, one bottom side, two ends and two lateral sides. The block has an H-shaped cross section, and the top side of the block has two higher side parts and one lower middle part, and the bottom side of the block has two higher side parts and one lower middle part. The wall of the irregular building blocks has high leakproof performance, high earthquakeproof stability and other advantages.

The invention discloses a bipolar zinc ion battery, which includes at least one unit group. The unit group includes at least one battery unit. The battery unit includes: an anode plastic current collector, an isolation film, and a cathode plastic current collector which are successively stacked and attached and sealed to each other, and a cathode active material layer as a cathode disposed insidethe cathode current collector, an anode active material layer as an anode disposed inside the anode current collector, and an electrolyte in the gaps of the cathode, anode, and the isolation film andcontaining a zinc compound and a porous ion channel disposed on the isolation film between the anode and the anode for the movement of zinc ions. The bipolar zinc ion battery has simple structure andlight weight, and has good safety performance and use performance.

The present invention is one kind of irregular building block and the wall structure therewith. The irregular building block is a longitudinal shaped material including one top side, one bottom side, two ends and two lateral sides. Each of the top side and the bottom side includes five parts in different heights. The wall of the irregular building blocks has high leakproof performance, high earthquakeproof stability and other advantages.

The invention provides a leakproof structural washing chain conveyor of an electrolytic copper plate. The leakproof structural washing chain conveyor comprises a main rack, an upper spraying pipe, a side face spraying pipe, a transmission chain, a chain supporting plate and close plates. The leakproof structural washing chain conveyor is characterized in that single close plate is a quadrate blocky stainless steel close plate with two folding sides at 90 degrees; the blocky close plates are matched in a convex-concave staggering manner and are fixed through stainless steel bolts and acid-resistant plastic spacers; a strong acid solution in the washing chain conveyor does not flow from a clearance between every two close plates by gravity under such structure; a glass silica gel layer used for sealing is additionally arranged in a joint at the outermost side of each close plate; spray-like acid liquid in the washing chain conveyor also does not overflow from such structure. According to the leakproof structural washing chain conveyor of the electrolytic copper plate, the natural rigidity of the close plates can be enhanced through the folding side structures at four sides of the close plates, and the close plates can be firm and durable; the close plates also can be manufactured from thinner stainless steel plates, so that the materials can be saved. The structure under bolt connection is dismountable and can be replaced by simply releasing the bolts during maintaining, so that the maintenance cost is saved.

The invention discloses a protective clothing digital customization system based on attitude collection, which includes a production platform and a model acquisition platform. The model acquisition platform includes a trajectory acquisition module, a classification module, and a model output module; The fixed-point posture image and the posture change image are converted into feature vectors with axis and time axis labels, and the feature vectors are input into the preset classification model to obtain the standard protective clothing size; based on the standard protective clothing size, the model output module searches the database from multiple Determine the cutting method that matches the size of the standard protective clothing among the three cutting methods, and control the manipulator to manufacture the protective clothing based on the cutting method; the trajectory acquisition module is used to collect changes in the user's body posture. The invention solves the technical problem of large manufacturing errors and low flexibility of conventional protective clothing, and can automatically customize according to the user's figure, with simple operation and good fit of the manufactured protective clothing.

The invention relates to a surface dust-free coating production line for auto parts. The surface dust-free coating production line for auto parts comprises a portal frame, a driving electric slide block, an inner diameter clamp, an externally connected ring, connecting frames and equally spaced spray heads. The driving electric slide block is mounted at the upper end of the portal frame, the externally connected ring is mounted at the lower end of the driving electric slide block, the lower end of the externally connected ring is connected to the portal frame in a sliding fit manner, the connecting frames are uniformly arranged on the inner wall of the externally connected ring along the circumferential direction, the equally spaced spray heads are uniformly arranged on the inner end surface of each connecting frame, the inner diameter clamp is mounted at the left end of the portal frame, and the inner diameter clamp is located in the externally connected ring. The surface dust-free coating production line can solve the problems that the thicknesses of coating liquids in parts of an exhaust tube are different as the coating distances from existing spray heads to the parts of the exhaust tube are different as the bore diameters of the parts of the exhaust tube are different, and the existing spray heads are likely to spray the coating liquids to the inner wall of the exhaust tube as the orifice of part of the exhaust tube is of an inclined structure and the like.
