[0001] The invention belongs to the technical field of air conditioning filter cleaning, and specifically refers to an air conditioning filter cleaning device for subway trains. Background Art

[0002] Cleaning the air conditioning filter of subway trains is an important task in subway vehicle maintenance. It is of great significance to ensure the air quality in subway cars and improve the riding experience of passengers.

[0003] The existing air conditioning filter cleaning device has the following problems: The existing air-conditioning filter cleaning device cannot clean the air-conditioning filter according to the degree of blockage. When the air-conditioning filter is severely blocked, it is difficult to remove the dust adsorbed on the surface of the air-conditioning filter using conventional spray cleaning power, and it also increases the cleaning time of the air-conditioning filter, greatly reducing the cleaning efficiency of the air-conditioning filter. Therefore, it cannot meet the existing cleaning requirements for the air-conditioning filter. Summary of the invention

[0006] As a further preferred embodiment of the present invention, the clamping mechanism includes a guide rail, a clamping frame and a clamping bolt, the guide rail is symmetrically arranged on the inner wall of the cleaning frame at one end away from the annular box, the clamping frame is slidably arranged between the guide rails, and multiple groups of the clamping bolts are penetrated through the inner wall of the clamping frame, and the clamping bolts are threadedly connected to the clamping frame; the cleaning mechanism includes a spray box and a linear nozzle, the spray box is slidably arranged between the inner wall of the cleaning frame on the side of the clamping frame away from the annular box, and multiple groups of the linear nozzles are connected and arranged on the side of the spray box close to the clamping frame; the mist supply mechanism includes an atomizing motor and a telescopic tube, the atomizing motor is arranged on the side of the annular box away from the cleaning frame, the mist exhaust end of the atomizing motor is penetrated through the inside of the annular box, and the telescopic tube penetrates the cleaning frame and is connected between the spray box and the annular box.

[0007] When in use, the pumping end of the atomizing motor is connected to the external water source. The atomizing motor atomizes the external water source into water mist and then transports it to the inside of the annular box. The water mist inside the annular box enters the spray box through the telescopic tube. The spray box sprays the water mist in a straight line through the linear nozzle. Put the air-conditioning filter into the clamping frame, rotate the clamping bolt, and the clamping bolt rotates along the inner wall of the clamping frame to fit the air-conditioning filter. The air-conditioning filter is fixed inside the clamping frame. At this time, the water mist sprayed by the linear nozzle rushes towards the air-conditioning filter to clean the air-conditioning filter.

[0008] Preferably, the flow-changing mechanism comprises an insulating block, a resistor rod, a mist extraction connector, an energy supply connector, an insulating frame, a conductive block and a linkage groove, wherein the linkage groove is arranged on the inner wall of the upper end of the cleaning frame, the linkage groove is through-arranged, the insulating blocks are symmetrically arranged on the upper wall of the cleaning frame on both sides of the linkage groove, the resistor rod is arranged between the insulating blocks, the mist extraction connector and the energy supply connector are respectively arranged on both sides of the resistor rod, the insulating frame passes through the linkage groove and is arranged on the upper wall of the clamping frame, the conductive block is arranged on the upper wall of the insulating frame, and the end of the conductive block away from the insulating frame is slidably arranged on the outside of the resistor rod; the distance-keeping mechanism comprises a receiving block, a distance-measuring ... A sensor, a driving cylinder and a cylinder frame, wherein the cylinder frame is arranged on a side of the annular box away from the cleaning frame, the driving cylinder penetrates the annular box and is arranged on the inner wall of the cylinder frame, the power end of the driving cylinder is connected to a side of the spray box away from the linear nozzle, the receiving blocks are symmetrically arranged on the upper walls at both ends of the clamping frame, the distance measuring sensors are symmetrically arranged on the upper walls at both ends of the spray box, and the receiving blocks and the distance measuring sensors are coaxially arranged horizontally; the resistance mechanism includes a mesh plate and a reset spring, the mesh plate is arranged on a side of the clamping frame away from the annular box, the reset spring is arranged between the mesh plate and the inner wall of the cleaning frame, and the reset spring is extended.

[0009] During use, due to the presence of dust on the surface of the air-conditioning filter, the gas permeability of the air-conditioning filter is reduced, resulting in greater resistance for the water mist when it rushes towards the air-conditioning filter. The water mist uses the deformation of the reset spring to push the air-conditioning filter, and the air-conditioning filter drives the clamping frame to slide along the guide rail away from the linear nozzle. The distance measuring sensor measures the distance between it and the receiving block through the distance measuring end. When the distance between the distance measuring sensor and the receiving block becomes longer, the power end of the driving cylinder extends and pushes the spray box to slide along the inner wall of the cleaning frame toward the clamping frame, thereby ensuring the distance between the linear nozzle and the air-conditioning filter, and ensuring the impact force of the water mist sprayed by the linear nozzle.

[0010] Specifically, the multi-tube dust collection mechanism includes a dust box, a dust net, a dust pump and a dust suction pipe. The dust box is arranged on the side of the cleaning rack away from the annular box, the dust net is arranged on the inner wall of the dust box, the dust pump is arranged on the side of the dust box away from the cleaning rack, the dust pump suction end is arranged through the inside of the dust box, and multiple groups of dust suction pipes are connected and arranged on the side wall of the dust box.

[0012] Wherein, a controller is provided on a side wall of one end of the cleaning rack close to the annular box.

[0013] Preferably, the controller is electrically connected to the atomizing motor, the distance measuring sensor, the driving cylinder and the dust collecting pump respectively.

[0014] Furthermore, the model of the controller is HAD-SC200.

[0015] Furthermore, the model of the distance measuring sensor is C1-JCS1501.

[0016] The beneficial effects achieved by adopting the above structure are as follows: Compared with the prior art, the present invention adopts the method of water mist impacting the air conditioning filter. Through the provision of a multi-hole spray washing mechanism, a resistance-adjusting dust removal mechanism and a multi-tube dust collecting mechanism, the dust content and adsorption strength adsorbed by the air conditioning filter can be measured under the coordinated use of the clamping mechanism, the cleaning mechanism, the mist supply mechanism, the flow-changing mechanism, the distance-keeping mechanism and the driving cylinder. Then, the spraying strength of the water mist can be adjusted according to the adsorption amount and adsorption strength of the dust on the surface of the air conditioning filter, and the cleaning speed of the air conditioning filter can be accelerated. The water mist pushes the air conditioning filter by the deformation of the reset spring, and the air conditioning filter drives the clamping frame to slide along the guide rail away from the linear nozzle. The distance measuring sensor measures the distance between it and the receiving block through the distance measuring end. When the distance between the distance measuring sensor and the receiving block becomes longer, the power end of the driving cylinder extends to push the spray washing box to slide along the inner wall of the cleaning frame toward the direction of the clamping frame, thereby ensuring the distance between the linear nozzle and the air conditioning filter, and ensuring the impact strength of the water mist sprayed by the linear nozzle.

[0025] The multi-tube dust collecting mechanism 29 includes a dust box 30, a dust collecting net 31, a dust collecting pump 32 and a dust suction pipe 33. The dust box 30 is arranged on the side of the cleaning rack 1 away from the annular box 2, the dust collecting net 31 is arranged on the inner wall of the dust box 30, the dust collecting pump 32 is arranged on the side of the dust box 30 away from the cleaning rack 1, the air suction end of the dust collecting pump 32 is arranged through the inside of the dust box 30, and multiple groups of dust suction pipes 33 are connected and arranged on the side wall of the dust box 30.

[0026] A controller 34 is disposed on a side wall of one end of the cleaning rack 1 close to the annular box 2 .

[0027] The controller 34 is electrically connected to the atomizing motor 12 , the distance measuring sensor 24 , the driving cylinder 25 and the dust collecting pump 32 , respectively.

[0028] The model of the controller 34 is HAD-SC200.

[0029] The model of the distance measuring sensor 24 is C1-JCS1501.

[0030] When in use, the pumping end of the atomizing motor 12 is connected to an external water source, the return spring 28 is extended, the power end of the driving cylinder 25 is shortened, the controller 34 controls the distance sensor 24 to start, and the distance sensor 24 detects the distance between it and the receiving block 23 in advance through the distance measuring end; The clamping bolt 7 is rotated, and the clamping bolt 7 is unscrewed from the inside of the clamping frame 6, and the air conditioning filter is placed in the inside of the clamping frame 6. The clamping bolt 7 is rotated along the inner wall of the clamping frame 6 to fit the air conditioning filter. The air conditioning filter is fixed inside the clamping frame 6. The controller 34 controls the atomizing motor 12 to start. The atomizing motor 12 atomizes the external water source into water mist and then transports it to the inside of the annular box 2. The water mist inside the annular box 2 enters the inside of the spray box 9 through the telescopic pipe 13; The spray box 9 sprays water mist in a straight line through the linear nozzle 10. At this time, the water mist sprayed by the linear nozzle 10 rushes to the air conditioning filter to clean the air conditioning filter; Due to the presence of dust on the surface of the air conditioning filter, the air passing rate of the air conditioning filter is reduced. When the dust and impurities adsorbed on the surface of the air conditioning filter are large or stubborn, the water mist will encounter greater resistance when rushing towards the air conditioning filter. The water mist uses the deformation of the reset spring 28 to push the air conditioning filter, and the air conditioning filter drives the clamping frame 6 to slide along the guide rail 5 away from the linear nozzle 10. The distance between the linear nozzle 10 and the air conditioning filter becomes longer, resulting in the linear nozzle 10 The flushing force on the surface of the air conditioning filter is weakened, and the clamping frame 6 drives the receiving block 23 away from the distance sensor 24; The detection distance of the distance sensor 24 is preset, and the controller 34 controls the distance sensor 24 to start. The distance sensor 24 measures the distance between it and the receiving block 23 through the distance measuring end. When the distance sensor 24 detects that the distance between it and the receiving block 23 becomes longer, in order to ensure that the impact force of the linear nozzle 10 spraying the air conditioning filter will not weaken with the increase of the distance, it is necessary to maintain the distance between the linear nozzle 10 and the air conditioning filter. At this time, the controller 34 controls the driving cylinder 25 to start, and the power end of the driving cylinder 25 extends to push the spray box 9. The spray box 9 slides along the inner wall of the cleaning frame 1 toward the clamping frame 6 to reset the distance between the linear nozzle 10 and the air conditioning filter, ensuring the cleaning force of the water mist sprayed by the linear nozzle 10 on the air conditioning filter. After the distance sensor 24 detects that the distance between it and the receiving block 23 reaches the preset distance through the distance measuring end, the controller 34 controls the power end of the driving cylinder 25 to stop moving; The clamping frame 6 drives the insulating frame 20 to move in the process of sliding along the guide rail 5 away from the annular box 2. In the initial state, the conductive block 21 is located outside the end of the resistor rod 17 close to the spray box 9, and the mist extraction connector 18 is electrically connected to the atomizing motor 12 and the end of the resistor rod 17 away from the spray box 9 respectively. The power supply connector 19 is electrically connected to the conductive block 21 and the controller 34 respectively. The controller 34 supplies power to the conductive block 21 through the power supply connector 19, and the conductive block 21 supplies power to the mist extraction connector 18 through the resistor rod 17. The mist extraction connector 18 supplies power to the atomizing motor 12. At this time, the resistance value in the circuit is in the normal setting state; When there is a lot of dust adsorbed inside the air conditioning filter, the mesh of the air conditioning filter will be blocked, increasing the resistance of the water mist. Under the resistance of the air conditioning filter, the clamping frame 6 drives the conductive block 21 to slide along the outside of the resistance rod 17 through the insulating frame 20, and the resistance rod 17 for power supply between the mist extraction connector 18 and the energy supply connector 19 is shortened. After the resistance rod 17 is shortened, the current passing into the atomizing motor 12 increases. The larger the current, the higher the speed of the atomizing motor 12, and the greater the pressure generated by the atomizing motor 12, which promotes the spraying force of the atomizing motor 12 to increase, so that the linear nozzle 1 0 generates water mist with relatively high pressure to clean the air conditioning filter. After the air conditioning filter is cleaned, the air passing rate of the air conditioning filter is improved, the resistance of the water mist is reduced, and the air conditioning filter is reset under the deformation of the reset spring 28, completing the cleaning of the air conditioning filter. Thus, the spray intensity of the atomizing motor 12 can be adjusted according to the blockage degree of the air conditioning filter surface, and the cleaning efficiency of the air conditioning filter is improved to a certain extent. At this time, the distance measuring sensor 24 detects that the distance between it and the receiving block 23 is shortened, and the controller 34 controls the power end of the driving cylinder 25 to shorten and reset to normal state; The controller 34 controls the dust collecting pump 32 to start. The dust-containing gas that passes through the air conditioning filter enters the dust collecting box 30 under the suction force of the dust collecting pump 32. The dust-containing gas enters the dust collecting box 30 through the dust suction pipe 33. The dust-containing gas is discharged after being filtered by the dust collecting net 31. Repeat the above operation when using it next time.
