In this embodiment: the corner position of the bottom end surface of the square shell 1 is fixedly connected with a supporting leg 43. The support feet 43 avoid the square housing 1 from directly contacting the ground.

The working principle of the invention is as follows: when the cooling water circulating system is used, the generator set 3 runs, the rotor of the generator set 3 rotates to drive the cooling fan 11 to rotate along with the turntable 12, in the process, the cooling water is pumped out of the cooling water circulating box 6 by the water pump of the generator set 3 and is sent to the position to be cooled of the generator set 3 through the second water pipe 9, the cooled cooling water carrying heat flows back into the cooling water circulating box 6 through the first water pipe 8, the rotating cooling fan 11 is used for helping the cooling water in the cooling water circulating box 6 to quickly dissipate heat in an air cooling mode, and then the cooling water is pumped to the generator set 3 to absorb heat, so that the cooling water circulates and reciprocates.

At the same time, the rotating turntable 12 drives the rotating arm 19 thereon to rotate, when the roller 20 at one end of the rotating arm 19 strikes the bottom end of the upper lifting plate 15, the roller 20 provides an upward force for the upper lifting plate 15, so that the upper lifting plate 15 slowly rises along the upper guide groove 14 of the upper guide plate 13, the top end of the upper lifting plate 15 extends out of the upper guide groove 14 to lift one side of the upper movable plate 27 upwards, and when the roller 20 is separated from the bottom end of the upper lifting plate 15, the upper movable plate 27 falls back to the original position under the action of self gravity, and in the process, the upper movable plate 27 moves downwards like a fan. When the roller 20 at one end of the rotating arm 19 strikes the top end of the lower lifting plate 23, the roller 20 provides a downward thrust for the lower lifting plate 23, so that the lower lifting plate 23 slowly descends along the lower guide groove 22 of the lower guide plate 21, the bottom end of the lower lifting plate 23 extends out of the upper guide groove 14 to jack up one side of the lower movable plate 28 downwards, at this time, the restoring spring 30 is compressed, and when the roller 20 is separated from the top end of the lower movable plate 28, the lower movable plate 28 lifts up under the action of the elastic potential energy of the restoring spring 30 to restore to the original position, and in the process, the upper movable plate 27 upwards expands the air flow like a fan. In addition, since the rotating arm 19 on the rotary table 12 continuously rotates, the upper movable plate 27 is in the process of closing and recovering the original position in the process of opening the lower movable plate 28, and the lower movable plate 28 is in the process of closing and recovering the original position in the process of opening the upper movable plate 27, the opening and closing of the lower movable plate 28 and the upper movable plate 27 are staggered, and the heat dissipation effect is prevented from being influenced by the air flow opposite impact. When the lower movable plate 28 is opened and the upper movable plate 27 is closed, the downward air flow can blow out the dust of the generator set 3 from the lower movable plate 28, thereby improving the practicability. Also, during the lowering of the lower lift plate 23, the lower slider 26 follows the lowering in the lower chute 24, the lower spring post 25 is compressed, and when the roller 20 is separated from the top end of the lower movable plate 28, the lower spring post 25 releases elastic potential energy to lift the lower lift plate 23 back to the original position; during the lifting of the upper lifting plate 15, the upper slider 18 follows the lifting in the upper chute 16, the upper spring post 17 is compressed, and when the roller 20 is separated from the bottom end of the upper lifting plate 15, the upper spring post 17 releases elastic potential energy to quickly pull the upper lifting plate 15 down to restore the original position.

In the running process of the generator set 3, the two sides of the generator set 3 are not blocked due to the arrangement of the square shell 1, so that the generator set 3 can perform horizontal convection cooling left and right, and the generator set 3 can be subjected to more omnibearing heat dissipation by being matched with the vertical convection cooling. In addition, when generating set 3 outdoor use runs into rainy day, the staff can also protect generating set 3 both sides through recoverable protection component and butt joint card solid subassembly, and concrete process is: one end of the waterproof cloth 34 is pulled out from the side opening of the circular groove 32, the pulled waterproof cloth 34 is wrapped around the generator set 3 along the side surface of the square shell 1, and finally one end of the waterproof cloth 34 is inserted into the strip-shaped groove 38 of the strip-shaped plate 37 and is screwed against the waterproof cloth 34 through the fastening bolts 40 in the threaded holes 39, in the process, the shaft lever 33 rotates, and the spiral spring 36 is tensioned to store elastic potential energy. When the protection is not needed, the fastening bolt 40 is unscrewed, the waterproof cloth 34 is separated from the strip-shaped plate 37, and the waterproof cloth 34 is quickly retracted into the circular groove 32 under the action of the elastic potential energy of the spiral spring 36. In addition, during the process of transporting the generator set 3, the worker can provide anti-collision protection for the two sides of the generator set 3 on the pulled waterproof cloth 34, namely, the air bags 41 are inflated through the air inflation holes 42, so that the anti-collision air cushion function is achieved, and when the anti-collision air cushion is not needed, only the air of the air bags 41 is needed to be discharged, and the waterproof cloth 34 is not influenced to be retracted into the circular groove 32.
