[0029] Sweep dirt mechanism includes rotating shaft 12 that rotates in the inside of L-shaped seat 9, rotating shaft 12 outside lower fixed sleeve has meshing bevel gear 29, L-shaped seat 9 top wall one side is fixedly installed with fixed plate 10, fixed plate 10 inside rotatingly penetrates swing shaft 13, swing shaft 13 one end outside is provided with engaging piece, swing shaft 13 far from fixed plate 10 one end outside lower fixedly installs sleeve 27, sleeve 27 inside lower is provided with elastic component;

[0030] As Figure 3 And Figure 5 Under the connection of fixed plate 10, swing shaft 13 penetrates from one end, so that the engaging piece of swing shaft 13 one end outside can be engaged with meshing bevel gear 29.

[0031] Engaging piece includes fixed sleeve 33 that is provided in swing shaft 13 one end outside, fixed sleeve 33 outside is fixedly installed with half-arc bevel gear 28, and half-arc bevel gear 28 and meshing bevel gear 29 are engaged;

[0032] As Figure 6As shown, the half-arc bevel gear 28 is sleeved on the outside of the swing shaft 13 through the fixed sleeve 33, so that the half-arc bevel gear 28 and the meshing bevel gear 29 can promote the sleeve 27 at the lower end of the swing shaft 13 to swing when the rotating shaft 12 rotates in the forward and reverse directions, and the half-arc bevel gear 28 always maintains the meshing state with the meshing bevel gear 29 in the process.

[0033] The cooling assembly includes a cooler 18 abutting against the inner wall of the circular partition cavity, and the cooler 18 is rotationally connected with the driving mechanism. The driving mechanism includes a rotating shaft 14 rotationally installed inside the flow pipe 5 and located inside the circular partition cavity.

The upper side of the outside of the rotating shaft 14 is connected with the rotating shaft 12 through the belt pulley assembly 23. The upper end of the rotating shaft 14 is fixedly installed with a stepping motor 7. The outside of the stepping motor 7 is installed on the upper surface of the flow pipe 5 through the fixedly installed frame 8.

[0034] As shown in Figure 1 , Figure 2 and Figure 5 , the cooler 18 is arranged at the inner wall of the circular partition cavity, so that the water in the water storage tank 6 can be controlled at a low temperature. When the airflow enters the circular partition cavity, the temperature of the airflow can be changed, so that the low-temperature airflow entering the inside of the prefabricated cabin body 1 can dissipate heat and improve the cooling effect.

[0035] The elastic assembly includes a sliding rod 32 slidingly installed in the sleeve 27. The sliding rod 32 is sleeved with a clamping sleeve 31 on the outside.

[0036] As shown in Figure 5 and Figure 6 , under the transmission connection of the belt pulley assembly 23, the rotating shaft 12 can drive the meshing bevel gear 29 at the lower end to rotate. The meshing bevel gear 29 meshes with the half-arc bevel gear 28 on one side, so that the swing shaft 13 makes an arc-shaped motion. The brush wheel 26 on the lower side of the outside of the swing shaft 13 swings left and right in the process. The roller 25 arranged on the end of the brush wheel 26 is elastically pressed by the spring 30, so that the brush wheel 26 can also rotate by itself and contact the upper surface of the filter screen 22 in the arc-shaped motion process, so as to ensure that the impurities filtered on the upper surface of the filter screen 22 can be cleaned.

[0037] Roller 25 with half-arc-shaped bevel gear 28 meshing connection from the midpoint of the arc-shaped guide frame 24 to both ends of the roller, under the elastic extension of spring 30, slide bar 32 and brush wheel 26 can cooperate with the left and right roller 25 roll, in turn, the swing shaft 13 when doing arc motion, the brush wheel 26 can be in contact with the filter screen 22 on the surface of a large area, so as to clean the dust on the surface of the filter screen 22.

[0038] The outer wall of the water storage tank 6 is fixedly installed with connecting blocks 17 on both sides, and the lower end of the connecting block 17 is fixedly installed with a bent rod 15. The outer part of the two bent rods 15 is connected by a fixedly arranged fixed rod 21. The outer wall of the fixed rod 21 is symmetrically provided with an inclined plate 20, and a plurality of spoiler plates 19 are fixedly installed on the upper surface of the inclined plate 20. The outer side of the rotating shaft 14 and above the fixed rod 21 are installed with a fan blade 16.

[0039] As shown in Figure 3 , Figure 4 and Figure 5 , under the connection of the connecting block 17, the bent rod 15 and the fixed rod 21 are fixedly arranged on the outer side of the water storage tank 6. Thus, the inclined plate 20 can be installed at both ends of the fixed rod 21. When the rotating shaft 14 drives the fan blade 16 to rotate, the airflow is brought to the surface of the inclined plate 20 on both sides. Under the arrangement of the plurality of spoiler plates 19, the airflow is dispersed in the prefabricated cabin main body 1. In turn, the airflow is more multi-directional to ventilate the inside of the prefabricated cabin main body 1.

[0040] It should be specially noted that a discharge pipe can be externally connected to the water storage tank 6 for later drainage work.

[0041] Working principle: in use, the ventilation equipment 2 can be used flexibly through the monitoring of the temperature control sensor 34, the water storage tank 6 can store cold water and rainwater through the water inlet 11, the airflow enters the circular cavity through the flow pipe 5, then contacts the cooler 18, so that the airflow is in a low-temperature state and enters the prefabricated cabin body 1, thereby facilitating the ventilation and cooling of the interior of the prefabricated cabin body 1, the step motor 7 drives the rotating shaft 14 to rotate, the fan blades 16 outside the rotating shaft 14 can rotate above the prefabricated cabin body 1, guide the airflow to the surfaces of the two symmetrically arranged inclined plates 20, and then the airflow is uniformly dispersed to all directions by the multiple groups of different direction spoilers 19 on the inclined plates 20, so as to accelerate the flow of the airflow in the prefabricated cabin body 1 and enhance the effect of ventilation and cooling. In addition, when the step motor 7 drives the rotating shaft 14 to rotate, the transmission connection of the belt pulley assembly 23 causes the rotating shaft 12 to rotate forward and backward, the meshing bevel gear 29 and the semicircular bevel gear 28 are positively and negatively meshed for half a circle, so that the sleeve 27 at the lower end of the swing shaft 13 and the brush wheel 26 can swing left and right. The roller 25 outside one end of the brush wheel 26 is elastically biased by the spring 30, so that the brush wheel 26 can also rotate by itself during the arc motion and contact the upper surface of the filter screen 22, so as to ensure that the impurities filtered on the upper surface of the filter screen 22 can be cleaned, and the effect of blocking impurities above the filter screen 22 is guaranteed.
