However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0026] Cooling water is stored in the water storage tank 6. Under the cold air transport of the cooling assembly and the ventilation mechanism, the cooling airflow is further dispersed inside the prefabricated cabin body 1. A temperature control sensor 34 is installed on the lower surface of the water storage tank 6.

[0027] The ventilation mechanism includes a ventilation device 2, the outside of the ventilation device 2 is fixedly mounted on the outer wall of one side of the prefabricated cabin body 1 through a fixedly arranged mounting frame 3, and the upper part of the interior of the ventilation device 2 is connected to the flow pipe 5 through a connectedly installed air duct 4;

[0028] like Figure 1 and Figure 2 As shown, the ventilation device 2 is a fan, and the temperature control sensor 34 can monitor the internal temperature of the prefabricated cabin body 1. The above are all existing technologies and will not be elaborated in detail.

[0029] The chip sweeping mechanism includes a rotating shaft 12 rotatably mounted inside the L-shaped seat 9, a meshing bevel gear 29 is fixedly mounted on the lower outer side of the rotating shaft 12, a fixed plate 10 is fixedly mounted on one side of the top wall of the L-shaped seat 9, a swing shaft 13 is rotatably inserted inside the fixed plate 10, a meshing member is disposed on the outer side of one end of the swing shaft 13, a sleeve 27 is fixedly mounted on the lower outer side of one end of the swing shaft 13 away from the fixed plate 10, and an elastic component is disposed on the lower inner side of the sleeve 27;

[0030] like Figure 3 and Figure 5 As shown, under the connection of the fixed plate 10 , the swing shaft 13 is inserted from one end, so that the engagement piece outside one end of the swing shaft 13 can be engaged with the engagement bevel gear 29 .

[0031] The meshing member includes a fixed sleeve 33 disposed outside one end of the swing shaft 13, and a semi-arc bevel gear 28 is fixedly mounted on the outer side of the fixed sleeve 33, and the semi-arc bevel gear 28 is meshedly connected with the meshing bevel gear 29;

[0032] like Figure 6As shown, the semi-arc bevel gear 28 is mounted on the outside of the swing shaft 13 through a fixed sleeve 33, so that the semi-arc bevel gear 28 and the meshing bevel gear 29 can cause 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. During the process, the semi-arc bevel gear 28 always maintains a meshing state with the meshing bevel gear 29.

[0033] The cooling assembly includes a cooler 18 that is clamped against the inner wall of the circular compartment. The cooler 18 is rotatably matched with the driving mechanism. The driving mechanism includes a rotating shaft 14 that is rotatably installed inside the circulation tube 5 and located inside the circular compartment. One end of the rotating shaft 14 is inserted into the cooler 18 and extends into the prefabricated cabin body 1. The upper part of the outer side of the rotating shaft 14 is connected to the rotating shaft 12 through a pulley assembly 23. A stepper motor 7 is fixedly installed on the upper end of the rotating shaft 14. The outer part of the stepper motor 7 is installed on the upper surface of the circulation tube 5 through a fixed frame 8.

[0034] like Figure 1 , Figure 2 and Figure 5 As shown, the cooler 18 is arranged on the inner wall of the circular compartment, which can control the low temperature of the water inside the water storage tank 6, and then when the airflow enters the circular compartment, it can change the temperature of the airflow, so that the low-temperature airflow enters the prefabricated cabin body 1 to dissipate heat and improve the cooling effect.

[0035] The elastic component includes a slide bar 32 slidably mounted inside the sleeve 27, a sleeve 31 is sleeved on the outside of the slide bar 32, a spring 30 is sleeved on the outside of the slide bar 32 and located above the sleeve 31, a brush wheel 26 is rotatably sleeved on the outside of the end of the slide bar 32 away from the sleeve 31, and a roller 25 is installed on the end of the brush wheel 26 away from the slide bar 32, an arc-shaped guide frame 24 is fixedly arranged on one side of the outer wall of the circulation tube 5, and the roller 25 rolls on the inner surface of the arc-shaped guide frame 24;

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

[0037] The roller 25 rolls from the midpoint of the arc-shaped guide frame 24 to both ends as the semi-arc bevel teeth 28 mesh with each other. Under the elastic expansion and contraction of the spring 30, the slide bar 32 and the brush wheel 26 can cooperate with the roller 25 to roll left and right. When the swing shaft 13 moves in an arc, the brush wheel 26 can contact a large area of ​​the upper surface of the filter 22, thereby cleaning away the dust on the upper surface of the filter 22.

[0038] Connecting blocks 17 are fixedly installed on both sides of the outer wall of the water storage tank 6, and bent rods 15 are fixedly installed on the lower ends of the connecting blocks 17. The two bent rods 15 are connected to each other through a fixedly arranged fixed rod 21. Inclined plates 20 are symmetrically arranged on both sides of the outer wall of the fixed rod 21, and multiple groups of spoilers 19 are fixedly installed on the upper surfaces of the inclined plates 20. Fan blades 16 are installed on the outer side of the rotating shaft 14 and above the fixed rod 21;

[0039] like Figure 3 , Figure 4 and Figure 5 As shown, under the connection of the connecting block 17, the bent rod 15 and the fixed rod 21 are fixedly arranged outside the water storage tank 6, so that 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 rotated and brought to the surface of the inclined plate 20 on both sides. Under the setting of multiple groups of spoilers 19, the airflow is dispersed inside the prefabricated cabin body 1, so that the airflow can ventilate the inside of the prefabricated cabin body 1 in a more multi-directional manner;

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

[0041] Working principle: When in use, the ventilation device 2 can be used flexibly through the monitoring of the temperature control sensor 34. The water tank 6 can store cold water and rainwater through the water diverter 11. The airflow enters the round cavity through the circulation pipe 5, and then contacts the cooler 18, so that the airflow enters the prefabricated cabin body 1 in the state of low-temperature airflow, thereby facilitating ventilation and cooling of the prefabricated cabin body 1. The stepper motor 7 drives the rotating shaft 14 to rotate, and the fan blades 16 outside the rotating shaft 14 can rotate above the inside of the prefabricated cabin body 1 to guide the airflow to the surface of the inclined plates 20 symmetrically arranged on both sides, and then the multiple groups of spoilers 19 in different directions on the inclined plates 20 evenly disperse the airflow to various places. In order to accelerate the flow of air inside the prefabricated cabin body 1 and enhance the ventilation and cooling effect, in addition, when the stepper motor 7 drives the rotating shaft 14 to rotate, through the transmission connection of the pulley assembly 23, the rotating shaft 12 is caused to rotate forward and reverse, and the meshing bevel gear 29 is meshed with the semi-arc bevel gear 28 for half a circle in the forward and reverse directions, so that the sleeve 27 and the brush wheel 26 at the lower end of the swing shaft 13 can swing left and right. The roller 25 arranged on the outside of one end of the brush wheel 26 is under the elastic pressure of the spring 30, so that the brush wheel 26 can 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 the filter screen 22 blocking impurities on the top is ensured.

[0042] The above shows and describes the basic features, main features and advantages of the present invention. It should be understood by those skilled in the art that the present invention is not limited to the above embodiments, and the above embodiments and descriptions are only the features of the present invention.
