[0020] Using the above solution: the door frame 100 can be fixed to the wall panel of the equipment room in the cabin with bolts; the cleaning mechanism 200 is used to clean the screen inside the air duct 600; the sealing mechanism 300 can seal the joint between the door panel 500 and the door frame 100, which can improve the sound insulation effect and make the maintenance door completely closed, so as to avoid excessive noise from the equipment room from affecting the cabin; the ventilation mechanism 400 can automatically adjust the tilt angle of the rotating plate 401 when the temperature in the equipment room is high or low, thereby automatically controlling the ventilation volume.

[0021] As shown in Figures 1 to 2 The inner wall of the air duct 600 is fixedly connected with a screen 800, the inner wall of the air duct 600 is provided with a dust box 900, and the inner wall of the air duct 600 is fixedly connected with a fan housing 700.

The air duct 600 is provided with a movable baffle, which can be connected by magnetic attraction, and the dust box 900 can be taken out for cleaning by opening the baffle.

[0023] As shown in Figures 3 to 6 The cleaning mechanism 200 further comprises a driving assembly, the driving assembly comprises a rotating rod 2001, the outer wall of the rotating rod 2001 is rotatably connected with a rotating shaft 2002, the outer wall of the rotating shaft 2002 is fixedly connected with a sprocket B210, the outer wall of the sprocket B210 is rotatably connected with a sprocket A208 through a chain 209, the outer wall of the sprocket A208 is fixedly connected with a bevel gear B207, and the outer wall of the driving gear 205 is fixedly connected with a bevel gear A206.

[0024] The driving assembly can control the cleaning mechanism 200 and the sealing mechanism 300 when the door plate 500 is opened and closed; the rotating shaft 2002 below the rotating rod 2001 is fixed on the air duct 600 and can rotate in the inner wall of the air duct 600, one end of the rotating rod 2001 away from the rotating shaft 2002 is connected with the moving block 303 in the sealing mechanism 300, and the moving block 303 can only move horizontally in the inner wall of the door frame 100; when the door plate 500 is opened, the air duct 600 pulls the corresponding end of the rotating shaft 2002 and the rotating rod 2001 to move outward synchronously, the other end of the rotating rod 2001 pulls the moving block 303 to move horizontally along the inner wall of the door frame 100, so that the rotating rod 2001 is in an inclined state and rotates around the rotating shaft 2002 as the center. Through the rotation of the rotating shaft 2002, the cleaning brush 201 in the cleaning mechanism 200 can be driven to move along the surface of the screen 800 for brushing and cleaning, and when the door plate 500 is closed, the driving assembly is reset and drives the cleaning brush 201 to move reversely to reset. Without the need for operators to dismount the air duct 600, the screen 800 can be cleaned, the structure is simple, no additional manual operation is needed, and the problem that too much dust attached to the screen 800 affects the ventilation effect is avoided.

[0025] As shown in Figures 3 to 6As shown, the cleaning brush 201 is in contact with the outer wall of the screen 800, the sliding block 202 is fixedly connected with the inner wall of the air duct 600, the threaded rod 203 is rotatably connected with the inner wall of the air duct 600, and the driving gear 205 is rotatably connected in the inner wall of the air duct 600; the rotating shaft 2002 is rotatably connected with the inner wall of the air duct 600, the sprocket A 208 is rotatably connected with the inner wall of the air duct 600, and the bevel gear B 207 is meshed with the bevel gear A 206.

[0026] With the above scheme: the sliding block 202 can only move horizontally in the air duct 600, when the rotating shaft 2002 rotates when the door plate 500 is opened, the rotating shaft 2002 will drive the sprocket B 210 to rotate synchronously, and the sprocket A 208 will rotate at the same speed through the transmission of the chain 209, which is a prior art, and the transmission of the sprocket and the chain 209 can be realized through the meshing of the tooth block and the tooth groove and the thrust of the chain 209 when the sprocket B 210 rotates; the sprocket A 208 drives the bevel gear B 207 to rotate, so that the bevel gear A 206 meshed therewith rotates synchronously, converting the horizontal rotation into vertical rotation, which can drive the threaded rod 203 to rotate synchronously through the meshing of the driving gear 205 and the driven gear 204, and the threaded rod 203 and the sliding block 202 are threadedly connected, so that the sliding block 202 drives the cleaning brush 201 to move horizontally in the inner wall of the air duct 600, and the cleaning brush 201 moves along the outer wall of the screen 800 to clean the attached dust; when the door plate 500 is closed, the rotating shaft 2002 will rotate in the opposite direction, the rotating rod 2001 will be flipped and reset, and under the action of the driving gear 205 and other structures, the cleaning brush 201 will also move in the opposite direction, and the cleaning mechanism 200 will be reset as a whole to complete a cleaning.

[0027] As shown in Figure 3 , Figure 4 and Figure 7 , Figure 8 , the sealing mechanism 300 comprises a sealing air bag 301, the outer wall of the sealing air bag 301 is connected with an air cylinder 302 through a connecting pipe 307, the inner wall of the air cylinder 302 is slidably connected with a pressing plate 306, the outer wall of the pressing plate 306 is fixedly connected with a traction rope 304, the outer wall of the traction rope 304 is fixedly connected with a moving block 303, the inner wall of the door frame 100 is rotatably connected with a rotating wheel 305, and the inner wall of the connecting pipe 307 is provided with a valve 308.

[0028] With the above scheme: the sealing air bag 301 is arranged around the outer wall of the door plate 500, and when the door plate 500 is closed, a certain gap is left between the rear end of the door plate 500 and the outer wall of the front end of the door frame 100, and the noise is transmitted from the gap, which has a great influence, the sealing air bag 301 can close the gap when it is inflated, so as to isolate the transmission of noise, and also to prevent water vapor outside the cabin from entering the equipment room; during the closing process of the door plate 500, the rotating rod 2001 will be flipped, as shown in Figure 8As shown, the end of the rotating rod 2001 connected with the moving block 303 moves to the right along the inner wall of the door frame 100. Since the traction rope 304 is fixed at the outer wall of the moving block 303 at both ends and is fixed at the outer wall of the pressing plate 306 at the other two ends, the moving block 303 can pull the pressing plate 306 to move to the left inside the air cylinder 302 when the moving block 303 moves to the right. Since the air cylinder 302 contains gas, the pressing plate 306 can press the gas to open the valve 308, and the gas enters the sealed air bag 301 through the connecting pipe 307. The maximum opening angle of the door plate 500 is 90°, and the pressing plate 306 moves to the right side of the connecting pipe 307 at most. When the door plate 500 is completely closed, the pressing plate 306 remains in place, and the gas in the sealed air bag 301 cannot open the valve 308 under the action of no pressure, so that the sealed air bag 301 remains in the inflated state.

[0029] As shown in Figure 3 , Figure 4 and Figure 7 , Figure 8 As shown, the sealed air bag 301 is fixedly connected to the outer wall of the door frame 100, the sealed air bag 301 and the air cylinder 302 are connected in communication through the connecting pipe 307, the traction rope 304 is wound on the outer wall of the rotating wheel 305, the moving block 303 is rotatably connected to the outer wall of the rotating rod 2001, and the moving block 303 is slidably connected to the inner wall of the door frame 100.

[0030] The above scheme is adopted: since the sealed air bag 301 will be collided synchronously during the closing of the door plate 500, the door plate 500 will first contact the sealed air bag 301 before being completely closed, and since the sealed air bag 301 is elastic, it can buffer the door plate 500 to a certain extent to prevent the door plate 500 or the door frame 100 from being damaged due to excessive force when the door plate 500 is closed. During the opening of the door plate 500, the rotating rod 2001 will be flipped and drive the moving block 303 to move to the left, at which time the traction rope 304 will pull the pressing plate 306 to move to the right. When the pressing plate 306 moves, it will suck air to form negative pressure inside the air cylinder 302. At this time, the gas in the sealed air bag 301 will open the valve 308 under the action of the pressure difference and enter the inside of the air cylinder 302, so that the sealed air bag 301 shrinks. At this time, the door frame 100 at the position of the sealed air bag 301 can be cleaned to prevent water vapor or dust from remaining on the surface of the sealed air bag 301, which may cause aging or mildewing risk on the contact surface of the door frame 100.

[0031] As shown in Figure 9 and Figure 10As shown, the ventilation mechanism 400 comprises a rotating plate 401, an outer wall of the rotating plate 401 is fixedly connected with a connecting shaft 402, an outer wall of the connecting shaft 402 is fixedly connected with an inner rod 403, an outer wall of the inner rod 403 is slidably connected with an outer rod 404, an inner wall of the air duct 600 is elastically connected with a moving rod 405 through a reset spring 406, the inner wall of the air duct 600 is rotatably connected with a roller 409, an outer wall of the roller 409 is wound with a pull rope 408, and the inner wall of the air duct 600 is fixedly connected with a bimetallic strip 407.

[0032] With the above scheme: the rotating plate 401 can be provided in multiple groups and vertically distributed on the outer wall of the door plate 500, and the rotating plate 401 remains in an inclined state, ventilation can be performed through the through slot at the rotating plate 401, the rotating angle of the rotating plate 401 can be automatically adjusted, the size of the through slot opening is changed, and thus the ventilation amount is adjusted; the inner rod 403 and the outer rod 404 form an extension rod, the moving rod 405 can remain in a vertical state and move up and down in the inner wall of the air duct 600, and drives the connecting shaft 402 to rotate, and thus the angle of the rotating plate 401 is adjusted; the bimetallic strip 407 is a prior art, one end is fixed in the inner wall of the air duct 600, and the other end is a movable end, when the external temperature rises, due to the characteristics of the bimetallic strip 407, the movable end will be bent, the movable end of the bimetallic strip 407 will be bent downward, and the bottom end of the pull rope 408 fixedly connected therewith is pulled downward.

[0033] As shown in the drawings, Figure 9 As shown in the drawings, Figure 10 As shown, the connecting shaft 402 is rotatably connected in the inner wall of the door plate 500, the outer rod 404 and the outer wall of the moving rod 405 are hinged, one end of the pull rope 408 is fixedly connected with the outer wall of the moving rod 405, and the other end of the pull rope 408 is fixedly connected with the movable end of the bimetallic strip 407; one end of the reset spring 406 is fixedly connected with the outer wall of the moving rod 405, the other end of the reset spring 406 is fixedly connected with the inner wall of the air duct 600, and the moving rod 405 is slidably connected in the inner wall of the air duct 600.

[0034] Adopt the above scheme: in normal state, the bimetallic strip 407 is linear, the ventilation mechanism 400 is the initial state, the reset spring 406 makes the moving rod 405 in a certain position, at this time, the tilt angle of the rotating plate 401 is small, the inner rod 403 and the outer rod 404 are in the elongated state, and the ventilation volume is small, when the temperature in the equipment room rises, the bimetallic strip 407 will be heated and bent, and pull the rope 408 down, the rope 408 moves through the roller 409, the roller 409 will rotate to reduce the friction between the two, and pull the moving rod 405 vertically down, drive the inner rod 403 and the outer rod 404 to overturn downward, and make the combined length of the two shorten, with the increase of temperature, the bending amplitude of the bimetallic strip 407 will be larger, the moving amplitude of the moving rod 405 will be larger, when the inner rod 403 and the outer rod 404 are in the horizontal state, the inner rod 403 is completely in the inner wall of the outer rod 404, at this time, the connecting shaft 402 drives the rotating plate 401 to overturn to the horizontal state, that is, the upper through slot of the door plate 500 can be opened to the maximum extent, the wind turbine shell 700 is combined with the temperature control system to increase the wind power, and the effect of ventilation and heat dissipation is improved; when the temperature in the equipment room decreases, the bimetallic strip 407 will bend upward and reset, the reset spring 406 pulls the moving rod 405 to reset, the inner rod 403 and the outer rod 404 are turned upward and elongated, the rotating plate 401 is turned upward, and the opening degree of the through slot is reduced, so that the ventilation volume is reduced, thereby realizing the effect of automatically adjusting the ventilation volume.

[0035] The working principle and use process of the application are as follows: When it is necessary to maintain or repair the cabin equipment room, the operator can pull the door plate 500 outward by 90 degrees, the rotating rod 2001 is turned around the rotating shaft 2002, the moving block 303 is slid laterally along the inner wall of the door frame 100 to the left side, when the moving block 303 moves to the left side, the traction rope 304 pulls the pressing plate 306 to slide to the right side, so that the negative pressure is formed in the air cylinder 302, the gas in the sealed air bag 301 is opened under the action of the pressure difference, and the valve 308 is opened, and the gas is returned to the air cylinder 302 through the connecting pipe 307, the sealed air bag 301 is gradually contracted, the contact surface of the sealed air bag 301 and the door frame 100 is exposed, the surface residual water vapor or dust is cleaned, and the sealed air bag 301 and the door frame 100 are prevented from mildewing and aging.

[0036] In the process of opening the door frame 100, the rotating shaft 2002 rotates with the door plate, driving the chain wheel B 210 and the chain wheel A 208 to rotate, and then driving the bevel gear B 207 and the bevel gear A 206 to rotate, driving the driving gear 205 and the driven gear 204 to rotate, and the threaded rod 203 rotates synchronously, the sliding block 202 moves along the inner wall of the air duct 600 under the drive of the threaded rod 203, and the cleaning brush 201 slides along the surface of the screen 800, and the cleaning brush 201 can brush off the dust attached to the surface of the screen, and the dust falls into the dust box 900; after the door plate 500 is completely opened, the operator can close the fan shell 700 and enter the equipment room for maintenance, or open the baffle to take out the dust box 900 to clean the internal dust.

[0037] After cleaning, the door plate 500 is closed, the rotating rod 2001 and the rotating shaft 2002 are reversed, the moving block 303 slides to the right along the inner wall of the door frame 100, the traction rope 304 pulls the pressing plate 306 to slide to the left, the pressing plate 306 extrudes the gas in the air cylinder 302, the gas pushes open the valve 308 in the connecting pipe 307, and the gas is injected into the sealed air bag 301 through the connecting pipe 307. The sealed air bag 301 inflates and expands until the door plate 500 completely fits the door frame 100, at this time the gap between the door plate 500 and the door frame 100 is completely filled with the air bag, achieving the effect of sound insulation and water vapor prevention, and the elasticity of the sealed air bag 301 can buffer the impact force when the door plate 500 is closed, protecting the door plate 500 and the door frame 100; when the rotating shaft 2002 reverses with the closing of the door plate 500, the cleaning brush 201 can slide reversely along the surface of the screen 800, and the cleaning mechanism 200 is reset.

[0038] When the temperature in the equipment room rises due to heat generated by the operation of the equipment, the movable end of the bimetallic strip 407 bends downward due to the difference in thermal expansion coefficient between the different metals, pulling the bottom end of the pull rope 408 to move downward, and the pull rope 408 pulls the moving rod 405 to slide vertically downward, stretching the reset spring 406; the moving rod 405 moves downward, driving the outer rod 404 and the inner rod 403 to flip downward, the combined length of the two is shortened, driving the connecting shaft 402 and the rotating plate 401 to flip horizontally, and the opening of the ventilation slot on the door plate 500 gradually expands, while the temperature control system drives the fan shell 700 to increase the wind power, and the hot air in the equipment room is quickly discharged through the air duct 600, achieving efficient heat dissipation.

[0039] When the temperature in the equipment room decreases, the movable end of the bimetallic strip 407 bends upward to reset, the pull rope 408 relaxes, and the reset spring 406 pulls the moving rod 405 to slide upward to reset, the moving rod 405 moves upward, driving the inner rod 403 and the outer rod 404 to flip upward, the inner rod 403 extends from the outer rod 404, the connecting shaft 402 drives the rotating plate 401 to flip upward, and the opening of the ventilation slot gradually decreases, thereby achieving the effect of automatically adjusting the ventilation volume.
