Description

Technical Field

[0001] The present invention relates to the technical field of control cabinets, in particular to a high-pressure control cabinet for ship boilers. Background Art

[0002] A ship boiler is a boiler that supplies steam to propel a ship's steam-powered machinery. A steam boiler control cabinet is an electrical cabinet used to control the steam boiler. Common boiler control cabinets are mostly formed by bending sheet metal, and their shells are relatively thin, serving only to accommodate various electrical components. Due to the high ambient temperature of the steam boiler control cabinet, cooling equipment needs to be installed in the control cabinet to cool the electrical components to avoid overheating and damage.

[0003] Most of the existing technologies dissipate heat by installing a cooling fan inside the steam boiler control cabinet in conjunction with an air outlet for circulating air. However, due to the high working environment temperature of the control cabinet, the cooling fan absorbs external air to dissipate heat inside the control cabinet, which is less effective and can easily cause overheating and damage to electrical components. Summary of the Invention

[0004] The present application provides a ship boiler high-pressure control cabinet, which has the function of cooling the external gas and then transporting it to the inside of the control cabinet for cooling the inside of the control cabinet, so that the temperature inside the control cabinet is not easily too high to cause damage to electrical components.

[0005] The ship boiler high-pressure control cabinet provided in this application adopts the following technical solutions:

[0006] A ship boiler high-pressure control cabinet comprises a control cabinet body; a cooling box is provided on the top surface of the control cabinet body; a ventilation pipe is fixedly connected to the inner wall of the cooling box; one end of the ventilation pipe extends to the outside of the cooling box, and the other end of the ventilation pipe extends to the inside of the control cabinet body and is connected with the inside of the control cabinet body; an exhaust fan is provided on the outer wall of the control cabinet body; the input end of the exhaust fan is fixedly connected to an air inlet pipe, and the output end of the exhaust fan is fixedly connected to an air outlet pipe; the end of the air outlet pipe away from the exhaust fan is connected with the end of the ventilation pipe extending outside the cooling box; a heat dissipation port is provided on the top surface of the control cabinet body; a heat dissipation channel connected with the heat dissipation port is provided at the position of the cooling box corresponding to the heat dissipation port; an infusion mechanism for conveying coolant into the cooling box is provided on the outer wall of the control cabinet body.

[0007] By adopting the above technical solution, the infusion mechanism transports the coolant in the box into the cooling box, and the exhaust fan is started to transport the gas from the external environment into the ventilation pipe through the air inlet pipe and the air outlet pipe. When the gas flows into the ventilation pipe, the coolant cools the gas in the ventilation pipe, so that the gas discharged from the ventilation pipe cools the inside of the control cabinet body after entering the inside of the control cabinet body, prompting the hot air flow inside the control cabinet body to be discharged to the external environment through the heat dissipation port, so that the heat inside the control cabinet body is not easy to be too high to cause damage to the electrical components, so that the control cabinet body can work normally.

[0008] Preferably, the infusion mechanism includes a box for holding cooling liquid; the box is fixedly connected to the outer wall of the control cabinet body, and a pump body is provided on the top surface of the box; the input end of the pump body is fixedly connected to a water inlet pipe, and the output end of the pump body is fixedly connected to a water outlet pipe; the end of the water inlet pipe away from the pump body extends to the interior of the box and is connected to the box; the end of the water outlet pipe away from the pump body is connected to the interior of the cooling box; a return pipe connected to the interior of the cooling box is fixedly connected to the outer wall of the cooling box; the end of the return pipe away from the cooling box is connected to the interior of the box, and a first valve is provided on the return pipe.

[0009] By adopting the above technical solution, the pump body is started to transport the coolant inside the box body to the cooling box through the water inlet pipe and the water outlet pipe, so that the coolant can cool the gas flowing in the ventilation pipe. After the coolant cools the gas in the ventilation pipe, the heat of the gas is transferred to the coolant, causing the coolant temperature to rise. The first valve is opened to allow the coolant to flow back into the box body, so that new coolant can enter the cooling box to cool the ventilation pipe, thereby facilitating continuous cooling of the gas in the ventilation pipe.

[0010] Preferably, a water collecting pipe is fixedly connected to the inner side wall of the top end of the box body; a plurality of drainage outlets connected to the interior of the water collecting pipe are provided on the water collecting pipe; the end of the return pipe away from the cooling box is connected to the interior of the water collecting pipe; a motor is installed on the outer side wall of the box body; the input end of the motor is fixedly connected to a rotating shaft extending into the cooling box; a straight plate is fixedly connected to the outer side wall of the rotating shaft; and a semiconductor refrigeration plate is fixedly connected to the outer side wall of the box body.

[0011] By adopting the above technical solution, the starting motor drives the rotating shaft and the straight plate to rotate. When the coolant in the return pipe enters the water collecting pipe, it flows back to the inside of the box through the drain port, thereby realizing the diversion of the coolant, which is convenient for better cooling treatment of the returning coolant. When the coolant flows down from the drain port, the rotating straight plate slaps the flowing coolant, causing the coolant to scatter onto the inner wall of the box and then flow down, which is convenient for the coolant to dissipate heat. The semiconductor arranged on the outer wall of the box is used to cool the coolant in the box, so that the coolant can be used multiple times, reducing the frequency of replacing the coolant.

[0012] Preferably, the top surface of the box is provided with an air inlet, and the outer wall of the box is provided with an exhaust port; the exhaust port and the motor are located on the same plane, and the inner wall of the exhaust port is rotatably connected to a first rotating shaft extending into the box; fan blades are fixed to the outer wall of the first rotating shaft, and the end of the first rotating shaft extending into the box is fixed to a first pulley; a second pulley is fixed to the outer wall of the rotating shaft close to the first pulley; a first belt is sleeved on the outside of the second pulley; the end of the first belt away from the second pulley is sleeved on the outside of the first pulley, and the first belt links the first pulley and the second pulley.

[0013] By adopting the above technical solution, the setting of the air inlet and the exhaust port enables the gas inside the box to circulate, and the motor drives the first pulley to rotate during the rotation of the rotating shaft. The cooperation of the first pulley, the second pulley and the first belt enables the rotating shaft to drive the first rotating shaft and the fan blades to rotate. The rotation of the fan blades causes the heat inside the box to be dissipated through the exhaust port, thereby cooling the coolant inside the box, so that the temperature of the coolant in the box is not easy to be too high.

[0014] Preferably, a first filter is fixedly connected to the inner wall of the heat dissipation port.

[0015] By adopting the above technical solution, the first filter is set to filter dust and impurities in the external environment, making it difficult for dust and impurities to enter the control cabinet body through the heat dissipation port and interfere with electrical components, so that the interior of the control cabinet body remains clean.

[0016] Preferably, a material receiving box located at the bottom of the heat dissipation port is fixedly connected to the inner wall at the top end of the control cabinet body; a second rotating shaft is rotatably connected to the inner wall at the bottom end of the material receiving box; a cleaning brush in contact with the first filter is fixedly connected to the end of the second rotating shaft close to the first filter; a transmission assembly is provided inside the box body that can drive the rotating shaft to rotate the second rotating shaft.

[0017] By adopting the above technical solution, the second rotating shaft is driven to rotate by the transmission assembly during the rotation of the rotating shaft, so that there is no need to add an additional driving element to drive the second rotating shaft to rotate. The second rotating shaft drives the cleaning brush to rotate during the rotation process, so that the cleaning brush cleans the first filter, making the mesh of the second filter less likely to be blocked, thereby allowing the heat inside the control cabinet body to dissipate, and the dust and impurities cleaned by the cleaning brush are collected by the material receiving box, so that the dust and impurities are not likely to fall on the electrical components and interfere with the electrical components.

[0018] Preferably, the bottom end of the second rotating shaft extends to the bottom of the material receiving box, and the end of the second rotating shaft extending to the bottom of the material receiving box is fixedly connected to the first bevel gear; the transmission assembly includes a third rotating shaft and a transmission member; the third rotating shaft is rotatably connected to the inner side wall of the control cabinet body, and the end of the third rotating shaft close to the first bevel gear is fixedly connected to the second bevel gear meshing with the first bevel gear; the end of the third rotating shaft away from the second bevel gear extends to the outside of the control cabinet body; the transmission member is arranged at the end of the third rotating shaft extending outside the control cabinet body, and the transmission member can enable the rotating shaft to drive the third rotating shaft to rotate.

[0019] By adopting the above technical solution, the third rotating shaft is driven to rotate by the synchronous member during the rotation of the rotating shaft, and the second bevel gear is driven to rotate during the rotation of the third rotating shaft. Under the meshing cooperation of the first bevel gear and the second bevel gear, the third rotating shaft drives the second rotating shaft to rotate, thereby realizing that the rotating shaft drives the second rotating shaft to rotate, thereby prompting the cleaning brush to clean the first filter, so that the mesh of the first filter is not easily blocked, ensuring that the heat generated by the electrical components inside the control cabinet body can be dissipated in time.

[0020] Preferably, a clearance hole is provided on the top surface of the box body; the transmission member includes a third pulley, a fourth pulley and a second belt passing through the clearance hole; the third pulley is fixed to the end of the third rotating shaft extending outside the control cabinet body; the fourth pulley is fixed to the outer side wall of the rotating shaft close to the third pulley; the second belt is arranged on the outside of the third pulley and the fourth pulley, and the second belt links the third pulley and the fourth pulley.

[0021] By adopting the above technical solution, the motor drives the fourth pulley to rotate during the rotation of the rotating shaft. Under the cooperation of the third belt, the fourth pulley and the second belt, the third rotating shaft rotates, so that the rotating shaft drives the third rotating shaft to rotate synchronously, and the setting of the give way hole makes way for the setting of the second belt.

[0022] Preferably, a second filter is fixedly connected to the inner side wall of the end of the air inlet pipe away from the exhaust fan.

[0023] By adopting the above technical solution, the second filter is used to filter the gas entering the control cabinet body, remove dust and impurities in the gas entering the control cabinet body, so that the electrical components inside the control cabinet body are not easily damaged by the interference of dust and impurities.

[0024] Preferably, a liquid infusion tube connected to the interior of the box is fixedly connected to the top surface of the box; a second valve is provided on the liquid infusion tube; a liquid discharge tube connected to the interior of the box is fixedly connected to the outer wall of the box; a third valve is provided on the liquid discharge tube.

[0025] By adopting the above technical solution, the coolant inside the box can be discharged after opening the third valve on the drain pipe, and then new coolant can be injected into the box through the replenishing pipe, thereby realizing the replacement of the coolant inside the box.

[0026] In summary, this application has the following beneficial effects:

[0027] 1. The exhaust fan transports the air from the external environment to the ventilation pipe, and the coolant in the cooling box cools the air in the ventilation pipe. The ventilation pipe is set to a bend to extend the time the gas circulates in the ventilation pipe, thereby prompting the coolant to fully cool the air in the ventilation pipe. The cooled air is then transported to the interior of the control cabinet through the ventilation pipe, prompting the heat inside the control cabinet to dissipate through the heat dissipation port, so that the temperature inside the control cabinet is not easily too high to cause damage to the electrical components, thereby protecting the electrical components inside the control cabinet.

[0028] 2. After cooling the ventilation pipe, the coolant enters the water collecting pipe through the return pipe. The coolant flows down in multiple streams through the drain port. The motor drives the straight plate to rotate, causing the straight plate to hit the coolant returning to the box, causing the coolant to scatter on the inner wall of the box and then return, which is convenient for the heat of the returning coolant to dissipate. The fan blades and semiconductor refrigeration chips work together to cool the coolant returning to the box, so that the coolant can be recycled and the frequency of coolant replacement is reduced.

[0029] 3. The rotating shaft drives the second rotating shaft to rotate during the rotation process, so that the cleaning brush cleans the first filter, reducing the possibility of clogging of the mesh of the first filter, so that the heat in the control cabinet body can be dissipated in time, and the dust and impurities cleaned by the cleaning brush fall into the receiving box for collection, so that the internal environment of the control cabinet body remains clean.

[0037] The present invention discloses a ship boiler high pressure control cabinet, such as Figure 1 and Figure 2As shown, it includes a control cabinet body 1, a cooling box 2, a ventilation pipe 21, an exhaust fan 3 and an infusion mechanism 4. The control cabinet body 1 is a cabinet body with a hollow interior and an opening on one side. The control cabinet body 1 is provided with a cabinet door 15 on the outer wall of the surface where the opening is located; the cooling box 2 is fixedly connected to the top surface of the control cabinet body 1; the ventilation pipe 21 is fixedly connected to the inner wall of the cooling box 2, and the ventilation pipe 21 is bent. One end of the ventilation pipe 21 passes through the side wall of the cooling box 2 and extends to the outside of the cooling box 2 body, and the other end of the ventilation pipe 21 passes through the bottom side wall of the cooling box 2 and the top side wall of the control cabinet body 1 and then extends into the control cabinet body 1; the exhaust fan 3 is fixedly connected to the outer wall of the control cabinet body 1 through a pad, the input end of the exhaust fan 3 is fixedly connected to the air inlet pipe 31, and the output end of the exhaust fan 3 is fixedly connected to the air outlet pipe 32. The end of the air outlet pipe 32 away from the exhaust fan 3 is connected to the end of the ventilation pipe 21 extending to the outside of the cooling box 2 through a flange. A heat dissipation port 11 is provided on the top surface of the control cabinet body 1, and a heat dissipation channel 22 connected to the heat dissipation port 11 is provided at a position corresponding to the heat dissipation port 11 on the cooling box 2. The infusion mechanism 4 is arranged on the side of the control cabinet body 1 away from the opening, and the infusion mechanism 4 is used to transport the coolant to the cooling box 2.

[0038] The coolant is delivered to the cooling box 2 through the infusion mechanism 4 so that the ventilation pipe 21 is immersed in the coolant. When the control cabinet body 1 is cooled, the exhaust fan 3 is started to deliver the gas from the external environment to the ventilation pipe 21 through the air inlet pipe 31 and the air outlet pipe 32. When the gas flows in the ventilation pipe 21, the coolant cools the gas, so that the gas is delivered to the inside of the control cabinet body 1, prompting the hot air flow inside the control cabinet body 1 to be discharged to the external environment through the heat dissipation port 11 and the heat dissipation channel 22, thereby achieving cooling of the control cabinet body 1 and protecting the electrical components.

[0039] like Figure 1 and Figure 3 As shown, the air inlet pipe 31 is horizontally arranged in an L shape, with the air inlet end of the air inlet pipe 31 facing downward. A second filter 311 is fixedly connected to the inner side wall of the end of the air inlet pipe 31 away from the exhaust fan 3.

[0040] When the gas from the external environment enters the air inlet pipe 31 , the second filter 311 filters the gas to remove dust and impurities contained in the gas, so that it is difficult for a large amount of dust and impurities to enter the control cabinet body 1 and cause damage to the electrical components.

[0041] like Figure 1 and Figure 2As shown, the infusion mechanism 4 includes a box body 41 for containing coolant and a pump body 42. The box body 41 is fixedly connected to the outer side wall of the control cabinet body 1 away from the opening. A liquid infusion tube 44 communicating with the interior of the box body 41 is fixedly connected to the top surface of the box body 41, and a second valve 441 is provided on the liquid infusion tube 44. A discharge pipe 45 communicating with the interior of the box body 41 is fixedly connected to the outer side wall of the box body 41 away from the control cabinet body 1, and a third valve 451 is provided on the discharge pipe 45; the pump body 42 is fixedly connected to the top surface of the box body 41, and an inlet pipe 421 is fixedly connected to the input end of the pump body 42. The end of the inlet pipe 421 away from the pump body 42 passes through the top side wall of the box body 41 and extends into the interior of the box body 41. The output end of the pump body 42 is fixedly connected to the outlet pipe 422. The end of the outlet pipe 422 away from the pump body 42 is fixedly connected to the side wall of the cooling box 2 and communicates with the interior of the cooling box 2.

[0042] After the coolant is injected into the box body 41 through the liquid replenishing pipe 44, the pump body 42 is started to transport the coolant inside the box body 41 to the cooling box 2 through the water inlet pipe 421 and the water outlet pipe 422, so that the ventilation pipe 21 is immersed in the coolant, and the coolant is used to cool the gas flowing in the ventilation pipe 21. The setting of the drain pipe 45 facilitates the discharge of the coolant in the box body 41 and the replacement of new coolant.

[0043] like Figure 1 、 Figure 2 and Figure 4 As shown, a water collecting pipe 43 is fixedly connected to the inner side wall of the top end of the box body 41, and a plurality of drain outlets 431 connected to the interior of the water collecting pipe 43 are fixedly connected to the outer side wall of the water collecting pipe 43. A return pipe 23 connected to the interior of the cooling box 2 is fixedly connected to the outer side wall of the cooling box 2, and a first valve 231 is provided on the return pipe 23. The end of the return pipe 23 away from the cooling box 2 passes through the top side wall of the box body 41 and is fixedly connected to the side wall of the water collecting pipe 43. The return pipe 23 is connected to the interior of the water collecting pipe 43. A motor 5 is installed on the outer side wall of the box body 41 away from the control cabinet body 1. The output end of the motor 5 is fixedly connected to a rotating shaft 51 extending to the bottom of the drain outlet 431. A pair of straight plates 511 are fixedly connected to the outer side wall of the rotating shaft 51. A plurality of semiconductor refrigeration plates 6 are fixedly connected to the outer side wall of the box body 41.

[0044] After the coolant has cooled the vent pipe 21, its temperature rises. The first valve 231 is opened to allow the coolant to flow into the water collecting pipe 43 through the return pipe 23, so that the coolant in the box body 41 can be transported to the cooling box 2 again to cool the vent pipe 21. The coolant in the water collecting pipe 43 flows back into the box body 41 in multiple streams after passing through the drain port 431. During the cooling liquid reflux process, the motor 5 is started to drive the rotating shaft 51 and the straight plate 511 to rotate. The straight plate 511 slaps the refluxed coolant, causing the coolant to scatter on the inner wall of the box body 41 and then flow down, which is convenient for the heat dissipation of the coolant. The semiconductor refrigeration plate 6 arranged on the outer wall of the box body 41 is used to cool the coolant inside the box body 41, so that the coolant in the box body 41 can be recycled, thereby reducing the frequency of replacing the coolant.

[0045] like Figure 2 and Figure 4 As shown, an air inlet 411 is provided on the top surface of the box body 41, and an exhaust port 412 is opened on the outer wall of the box body 41 on the side where the motor 5 is located. The inner wall of the exhaust port 412 is rotatably connected to the first rotating shaft 7 extending into the interior of the box body 41. The first rotating shaft 7 is located on the outer wall of the box body 41 and is fixed with a fan blade 71. The end of the first rotating shaft 7 extending into the box body 41 is fixed with a first pulley 72, and the outer wall of the rotating shaft 51 close to the first pulley 72 is fixed with a second pulley 73. A first belt 74 is sleeved on the outside of the first pulley 72, and the end of the first belt 74 away from the first pulley 72 is sleeved on the outside of the second pulley 73. The first belt 74 links the first pulley 72 and the second pulley 73.

[0046] During the rotation of the rotating shaft 51, the first rotating shaft 7 is driven to rotate through the cooperation of the first pulley 72, the second pulley 73 and the first belt 74, and the first rotating shaft 7 drives the fan blades 71 to rotate. The rotation of the fan blades 71 causes the accumulated heat inside the box 41 to be discharged through the exhaust port 412, so that the coolant in the box 41 has a good cooling effect.

[0047] like Figure 4 and Figure 5 As shown, a first filter 111 is fixedly connected to the inner wall of the heat dissipation port 11, a receiving box 12 located at the bottom of the heat dissipation port 11 is fixedly connected to the inner wall of the top end of the control cabinet body 1, a second vertically arranged rotating shaft 13 is rotatably connected to the inner wall of the bottom end of the receiving box 12, a cleaning brush 14 in contact with the first filter 111 is fixedly connected to the top end of the second rotating shaft 13, and a transmission assembly 8 is provided in the box body 41, which can drive the second rotating shaft 13 to rotate by the rotating shaft 51.

[0048] The first filter 111 is configured to filter dust and impurities, preventing dust and impurities in the external environment from easily entering the interior of the control cabinet body 1 through the heat dissipation port 11. The rotating shaft 51 drives the second rotating shaft 13 to rotate via the transmission assembly 8 during rotation, and the cleaning brush 14 cleans the first filter 111, preventing the mesh of the first filter 111 from being easily clogged, thereby facilitating the discharge of heat from the interior of the control cabinet body 1 through the heat dissipation port 11. The receiving box 12 is configured to collect dust and impurities that fall from the first filter 111, preventing dust and impurities from easily falling onto electrical components.

[0049] like Figure 4 and Figure 5 As shown, the bottom end of the second rotating shaft 13 passes through the side wall of the bottom end of the material receiving box 12 and extends to the bottom of the material receiving box 12. The transmission assembly 8 includes a first bevel gear 131 fixedly connected to the bottom end of the second rotating shaft 13, a third rotating shaft 81 and a transmission member 82 that enables the rotating shaft 51 to drive the third rotating shaft 81 to rotate; the third rotating shaft 81 is rotatably connected to the inner wall of the box body 41, and the third rotating shaft 81 is horizontally arranged. The end of the third rotating shaft 81 close to the first bevel gear 131 is fixedly connected to the second bevel gear 811 that meshes with the first bevel gear 131, and the end of the third rotating shaft 81 away from the second bevel gear 811 passes through the side wall of the control cabinet body 1 and extends to the outside of the control cabinet body 1. The transmission member 82 is arranged at the end of the third rotating shaft 81 extending outside the control cabinet body 1.

[0050] During the rotation of the rotating shaft 51, the third rotating shaft 81 and the second bevel gear 811 are driven to rotate through the transmission member 82. Under the engagement of the first bevel gear 131 and the second bevel gear 811, the second rotating shaft 13 is driven to rotate, thereby enabling the cleaning brush 14 to perform cleaning work.

[0051] like Figure 4 and Figure 5 As shown, a clearance hole 413 is provided on the top surface of the box body 41; the transmission member 82 includes a third pulley 821, a fourth pulley 822 and a second belt 823 passing through the clearance hole 413; the third pulley 821 is fixedly connected to the end of the third rotating shaft 81 extending outside the control cabinet body 1; the fourth pulley 822 is fixedly connected to the outer wall of the rotating shaft 51 close to the third pulley 821; the second belt 823 is sleeved on the outside of the third pulley 821 and the fourth pulley 822, and the second belt 823 enables the third pulley 821 and the fourth pulley 822 to be linked.

[0052] Through the cooperation of the third pulley 821, the fourth pulley 822 and the second belt 823, the rotating shaft 51 drives the third rotating shaft to rotate during the rotation process, so that the rotating shaft 51 drives the second rotating shaft 13 to rotate, reducing the use of driving elements and saving resources.

[0053] Working principle: The coolant is injected into the box body 41 through the liquid replenishing pipe 44, and the coolant inside the box body 41 is transported to the cooling box 2 through the water inlet pipe 421 and the water outlet pipe 422 through the pump body 42, so that the ventilation pipe 21 is immersed in the coolant, and the exhaust fan 3 is started so that the gas from the external environment is filtered through the second filter 311 and then transported to the ventilation pipe 21 through the air inlet pipe 31 and the air outlet pipe 32. When the gas flows in the ventilation pipe 21, the coolant in the cooling box 2 cools the gas, so that the gas entering the control cabinet body 1 from the ventilation pipe 21 cools the inside of the control cabinet body 1, and causes the heat in the control cabinet body 1 to be discharged to the outside of the control cabinet body 1 through the heat dissipation port 11 and the heat dissipation channel 22. The first filter 111 provided on the heat dissipation port 11 is used to filter dust from the external environment, so that dust is not easy to enter the inside of the control cabinet body 1 and cause damage to electrical components;

[0054] After the coolant cools the vent pipe 21, the temperature of the coolant itself rises, and the first valve 231 is opened to allow the coolant to enter the water collecting pipe 43 through the return pipe 23. The coolant in the water collecting pipe 43 is divided through the drain port 431 and flows into the box body 41 in multiple streams. During the process of the coolant reflux, the motor 5 is started to drive the rotating shaft 51 and the straight plate 511 to rotate. During the rotation of the straight plate 511, the coolant falling from the drain port 431 is hit. The coolant is scattered on the inner wall of the box body 41 and then flows down, which is convenient for dissipating the heat on the coolant. The semiconductor refrigeration plate 6 provided on the outer wall of the box body 41 is used to cool the coolant in the box body 41, so that the coolant can repeatedly cool the vent pipe 21, thereby reducing the number of times the coolant is replaced.

[0055] During the rotation of the rotating shaft 51, the first pulley 72, the second pulley 73 and the first belt 74 cooperate to drive the rotating shaft 51 to rotate the first rotating shaft 7 and the fan blades 71. During the rotation of the fan blades 71, the heat inside the box 41 is dissipated through the exhaust port 412, and the coolant inside the box 41 is dissipated to dissipate heat.

[0056] During the rotation process, the rotating shaft 51 drives the third rotating shaft 81 to rotate through the cooperation of the third pulley 821, the fourth pulley 822 and the belt. Under the engagement of the first bevel gear 131 and the second bevel gear 811, the third rotating shaft 81 drives the second rotating shaft 13 to rotate, so that the cleaning brush 14 cleans the first filter 111, reducing the possibility of clogging of the mesh of the first filter 111, so that the heat in the control cabinet body 1 can be dissipated in time, and the cleaning brush 14 cleans the dust and impurities that fall into the material receiving box 12 for collection, so that the internal environment of the control cabinet body 1 remains clean.

[0057] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
