At the same time, the operation range is large, which is convenient for automated assembly. At the same time, the assembly is more stable, which can better meet the needs of assembly and combination, thereby improving the service life.

[0022] 1. A second spring is nested and connected through the outer surface of the connecting shaft column, and the single supporting outer plate is arranged in a "V" shape at the inner end of the prefabricated top plate. In winter, since the prefabricated cabin is used outdoors, snow will accumulate on the upper end of the prefabricated cabin, which is difficult to remove. Under the sun, water will accumulate and affect the use. At this time, the first motor can be started. When the first motor is started, the movement of the bearing plate drives the supporting outer plate to rotate inside the bearing plate and the first connecting plate. Since the length of the supporting outer plate remains unchanged, the prefabricated top plate is rotated at the inner end of the auxiliary block, and the accumulated snow is tilted to automatically fall and clean up;

[0023] The outer supporting plate is further supported by the second spring and the first spring respectively with the first connecting plate and the inner connecting plate to form a sliding rotating structure, the adjusting rod is connected to the bearing plate in a threaded manner, and the threads at the front and rear ends of the adjusting rod are in opposite directions, when the first motor is started to drive the adjusting rod to rotate, the bearing plate moves relatively, and at the same time, when the outer supporting plate rotates, the first spring and the second spring are set to expand and contract, and the prefabricated top plate is shaken while rotating and tilting, thereby achieving a better cleaning effect, which is convenient for use when snow accumulates in winter;

[0024] Furthermore, the first connecting door is opened, and the interior of the prefabricated bottom plate can be entered to work, and the first motor is started to drive the adjusting rod to rotate. The outer end surface of the prefabricated board wall is provided with connecting outer plates at equal intervals, and the interior of the connecting outer plates is provided with an arc-shaped groove structure.

[0025] 2. The second connecting plate is connected to the first connecting plate and the connecting strip by meshing, and the left and right sides of the connecting strip are evenly spaced with block structures, and the directions of the block structures are respectively set at the upper end and the left end of the connecting strip, and the connecting strip is meshed with the connecting plate through the block structure at its left end. When assembly is required, the first connecting door and the second connecting door are first opened, and a person enters the prefabricated board wall. The first connecting plate is rotated by starting the second motor, and the second connecting plate is rotated at the same time as the first connecting plate is rotated, thereby improving the level of automation;

[0026] Furthermore, the second connecting plate drives the connecting strip to move, and then the second motor in the prefabricated cabin on the other side that needs to be spliced ​​moves in the opposite direction, so that the connecting plate rotates, and the first positioning block and the limiting block rotate and protrude from the outer end of the prefabricated panel wall, so that the second positioning block of the prefabricated cabin on one side is connected with the limiting block of the prefabricated cabin on the other side.

The first positioning block is connected to the limiting block by rotation, and the limiting block is connected with the support rod, and the support rod is connected with the support ring by threading. The square positioning block and the connecting strip are relatively slidably arranged, and the four corners of the prefabricated board wall outside the square positioning block are provided with connecting grooves of arc-shaped groove structure. After the second motor is started, the connecting strip is moved, so that the first positioning block and the second positioning block protrude from the outer end of the prefabricated board wall. At this time, the support rod is respectively passed through the inside of the second positioning block and the limiting block, and then the support ring is rotated to move the support ring inside the support rod, thereby increasing the stability of the connection after splicing;

[0028] Furthermore, the second connecting plate is connected to the first connecting plate and the connecting strip in an engaging manner, and block structures are evenly spaced on the left and right sides of the connecting strip, and the directions of the block structures are respectively set at the upper end and the left end of the connecting strip. After disassembly, the support rod is separated from the second positioning block and the limiting block, and then the second motor is started to make the second positioning block rotate in the arc groove opened in the prefabricated panel wall. At the same time, the limiting block rotates inside the first positioning block to prevent the operation of the second positioning block from being blocked, thereby improving work efficiency.
