The present invention relates to the field of solar energy, in particular to a solar panel, comprising an aluminum alloy placement plate, a solar panel is arranged inside the aluminum alloy placement plate, and the aluminum alloy placement plate wraps around and one side of the solar panel, The side of the aluminum alloy placement plate away from the solar panel is symmetrically provided with two support plates, and the vertical section of the support plates is arc-shaped. In the present invention, the operator can quickly carry the entire device on his back through the arc-shaped plate, the fixed plate, the aluminum alloy placement plate and the solar panel, and the solar panel and the operator are tightly connected without using external force, which is convenient for the operator to bind and loosen device body.

The invention discloses an automobile engine balance weight which is easy to install, which comprises a connection platform, a locking block and a balance weight body. Engraved with an engaging groove, the engaging groove forms a disassembly structure with the engaging block and the fixing block, and the engaging groove matches the size between the engaging block and the fixing block, and the engaging block is engaged and slidably connected A fixing block is fixed on the inner side of the inner wall of the engaging groove and on the right side of the engaging block by heat welding. In the easy-to-install automobile engine balance block, the connection blocks are mutually symmetrical with respect to the longitudinal central axis of the connection platform, which facilitates the connection between the support plate and the connection block. The engaging groove and the engaging block are slidably engaged and connected, so that the engaging groove, the engaging block and the fixing block are connected and fixed, and the fixing block can increase the stress of the engaging block.

The invention provides an electric bridge-type scaffold. The electric bridge-type scaffold comprises a lower framework, a motor, an upper framework and an operating platform; the motor is installed inthe middle of the left side of the lower framework, the upper framework is welded to the top of the lower framework, and the operating platform is arranged at the inner sides of the lower framework and the upper framework; outer frames are welded to the outer sides of the left and right sides of the lower framework and the upper framework, upright rods are vertically welded to the interiors of the outer frames, and anti-falling mechanisms are arranged at the outer sides of the upright rods; transverse rods are inserted in the outer sides of the lower framework and the upper framework, vertical rods are inserted between the transverse rods, six fixed pulleys are arranged and equally divided into two groups in two lines, the fixed pulleys in the middles of the inner sides of the left and right sides of the lower frame are connected through a connecting rod, and all the fixed pulleys are connected through chains. According to the electric bridge-type scaffold, through the arrangement ofa series of structures, the scaffold has the advantages of being convenient to install, high in safety and the like.

The invention provides a wall structure suitable for pipeline communication and a construction method thereof, belonging to the technical field of wall construction, comprising: a wall body with a pipeline inside, and one end of the pipeline communicates with the outside of the wall body; decoration The board is laid on the wall surface of the wall body; the reinforcement board is arranged between the wall body and the decorative board, and the decorative board and the reinforcement board are provided with openings corresponding to each other and connected with the pipeline, and the water outlet parts are suitable for passing through The opening communicates with the pipeline. The present invention provides a wall structure suitable for pipeline communication. A reinforcing plate is provided between the joint between the decorative plate and the wall body. The reinforcing plate is used to reinforce the decorative plate. When the water outlet part passes through the decorative plate and the reinforcing plate When the opening of the pipe is connected to the pipeline, the reinforcing plate disperses the force exerted by the water outlet part on the decorative plate, so that the decorative plate can bear a large external force and is not easily damaged.
