Description

Technical Field

[0001] The invention relates to the field of mechanical technology, and in particular to an electric control adjustment component and a crane telescopic arm comprising the component. Background Art

[0002] A crane refers to a multi-action lifting machinery that vertically lifts and horizontally moves heavy objects within a certain range. It is also called an overhead crane, overhead crane, or crane. Some of the working characteristics of lifting equipment are intermittent movements, that is, the corresponding mechanisms of material picking, transportation, unloading and other actions work alternately in one working cycle, and the parameters of the crane are set through electronic control adjustment components.

[0003] The Chinese patent with application number 202320101357.3 discloses a dustproof structure of an electric control box for a crane. When the electric control box of the crane is used, the air filter is clamped by the filter box, and the side groove facilitates the clamping and sliding insertion of the air filter. Then the filter box is clamped with the clamping block to adsorb the dust entering from the heat dissipation holes, thereby protecting the electrical components inside the box and reducing the adhesion of internal dust to the electrical components. The clamping of the side groove with the air filter facilitates the replacement and cleaning of the air filter at a later time. The setting of the air filter avoids the heat dissipation effect of dust on the electrical components, and at the same time avoids the reduction of the service life of the electrical components.

[0004] According to the above-mentioned prior art, it is found that during use, since the working environment of the crane telescopic arm is generally in the construction area, and the air in the construction area contains a large amount of dust particles and impurities, the dust particles will accumulate on the outside of the dustproof structure during long-term use and will block the inside of the dustproof structure, thereby affecting the heat dissipation efficiency of the overall electric control box. Even if the air filter is quickly disassembled through the snap-on air filter, it needs to be disassembled frequently, which increases the work intensity of the construction personnel. In addition, in order to suppress the continuous floating of dust particles in the construction area, atomization equipment is usually used to spray water into the air to achieve dust reduction of dust particles in a floating state. However, in this process, air containing moisture will enter the interior of the electric control box. Although the moisture in the air can be absorbed by the desiccant in the electric control box, the desiccant will be in a saturated state over time, making it impossible to continue to absorb moisture in the air. As a result, the air with high humidity enters the electric control box and causes damage to the circuit structure in the circuit board.

[0005] Therefore, it is necessary to solve the above problems by means of an electric control adjustment component and a crane telescopic arm including the component. Summary of the invention

DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0022] The present invention provides Figures 1 to 11 An electric control adjustment component is shown, including a cantilever electric control warehouse 201, wherein ventilation slots 202 are provided on the left and right sides of the cantilever electric control warehouse 201, and the interiors of the two ventilation slots 202 are provided with pipes 207 matched with the ventilation slots 202, and the interiors of the two pipes 207 are provided with first electric control slide rails, and the two first electric control slide rails are provided with sliding plates 205 through electromagnetic sliders 223, and the two sliding plates 205 are provided with micro motors on the sides close to the electromagnetic slider 223, and the micro motors are used to control the sliding plates 205 to rotate, and the two sliding plates 205 are provided with first filter plates 208 and second filter plates 209 on the sides away from the electromagnetic slider 223, and the different surfaces of the first filter plate 208 and the second filter plate 209 are provided with mutually matched electromagnets and first magnetic blocks, respectively.

[0023] like Figure 4 , Figure 7 and Fig. 9As shown, an exhaust slot is provided at the top of the cantilever electric control chamber 201, and a sealing plate 221 is movably provided inside the exhaust slot, and an annular electromagnet 222 is provided at the bottom of the sealing plate 221 through a second compression spring 220, and the outer surface of the annular electromagnet 222 is connected to the inner wall of the exhaust slot, and a second magnetic block is provided at the bottom of the sealing plate 221, and a dehumidification chamber 218 is provided at the top of the inner wall of the cantilever electric control chamber 201, and a movable filter plate 212 is movably provided at the bottom of the inner wall of the dehumidification chamber 218. By setting the movable filter plate 212, when the gas containing moisture enters the cantilever electric control chamber 201, it will rise to the vicinity of the movable filter plate 212 and enter the dehumidification chamber 218 through the through holes on the movable filter plate 212. Inside, the regeneration desiccant above the supporting plate 211 is used to absorb moisture in the air, so as to avoid the cantilever electric control cabin 201 being in a humid state for a long time and causing a short circuit in the circuit board 219, and the surface of the movable filter plate 212 is interconnected with the supporting plate 211 through the support 214, and the regeneration desiccant is placed on the surface of the supporting plate 211, and a heat conducting plate 210 is provided on the top of the inner wall of the dehumidification cabin 218, and the heat conducting plate 210 is located above the supporting plate 211, and a first compression spring 213 is provided on the surface of the movable filter plate 212, and the movable filter plate 212 is elastically connected to the heat conducting plate 210 through the first compression spring 213, and the supporting plate 211 is located between the movable filter plate 212 and the heat conducting plate 210.

[0024] When in use, the exhaust slots, pipes 207, first filter plates 208 and second filter plates 209 arranged on both sides of the cantilever electric control compartment 201 allow external air flow to enter the cantilever electric control compartment 201 from the exhaust slots on either side of the cantilever electric control compartment 201, and pass through the first filter plate 208 and the second filter plate 209 at the same time. The sieve holes on the first filter plate 208 and the second filter plate 209 are used to block dust in the air, preventing dust from entering the cantilever electric control compartment 201 and causing the circuit board 219 to increase in temperature and cause a short circuit. In addition, if the humidity in the external air is high at this time, the regenerated desiccant on the top of the inner wall of the cantilever electric control compartment 201 is used to absorb moisture in the cantilever electric control compartment 201, preventing moisture brought by humid gas from entering the cantilever electric control compartment 201 and causing a short circuit in the circuit board 219.

[0025] like Figure 8 , Fig.10 and Fig.11 As shown, a heating module 215 is provided on the upper surface of the heat conducting plate 210, and the heating module 215 heats the regenerated desiccant through the heat conducting plate 210, a heat dissipation aluminum sheet 217 is provided on the upper surface of the heating module 215, an exhaust fan 216 is provided on the surface of the heat dissipation aluminum sheet 217, and the exhaust fan 216 is provided with a driving motor inside. An air intake plate 224 is provided on one side of the inner wall of the dehumidification bin 218, and the air intake plate 224 is located at one side edge of the heat conducting plate 210, an air intake hole is opened inside the air intake plate 224, and the exhaust fan 216 is located at the bottom of the exhaust slot.

[0026] During use, by setting a heating module 215 on the heat conducting plate 210, and setting a heat dissipation aluminum sheet 217 and an exhaust fan 216 on the heating module 215, when the regenerated desiccant is in a saturated state, it cannot continue to absorb moisture in the gas. At this time, the heating module 215 is turned on to transfer heat to the heat conducting plate 210, and the heat conducting plate 210 distributes the heat generated by the heating module 215 to the regenerated desiccant on the load-bearing plate, so that the moisture absorbed in the regenerated desiccant can be evaporated and gasified and discharged to the outside of the cantilever electric control cabin 201 through the exhaust fan 216, so that the regenerated desiccant can continue to work and absorb moisture in the gas in the cantilever electric control cabin 201, thereby avoiding frequent replacement of the regenerated desiccant and increasing the work intensity of the staff.

[0027] like Figure 3 As shown, a hinge shaft 204 is provided on the outer surface of the cantilever electric control compartment 201, and the cantilever electric control compartment 201 is provided with a compartment door 203 through the hinge shaft 204, and the number of the compartment door 203 and the hinge shaft 204 are both provided in two, and the two compartment doors 203 and the hinge shaft 204 are relatively arranged on the left and right sides of the cantilever electric control compartment 201, and a circuit board 219 is provided on one side of the inner wall of the cantilever electric control compartment 201, and the circuit board 219 is fixed at the middle position of the inner wall of the cantilever electric control compartment 201, and a sealing gasket is provided at the contact between the two compartment doors 203 and the cantilever electric control compartment 201. When the two compartment doors 203 are in a closed state, the interior of the cantilever electric control compartment 201 is in a sealed state, and the outer surfaces of the two compartment doors 203 are provided with grooves 206 for opening the compartment doors 203.

[0028] When in use, by setting a hinge shaft 204 and a compartment door 203 on the left and right sides of the cantilever electric control compartment 201, and setting a sealing gasket at the edge where the compartment door 203 contacts the cantilever electric control compartment 201, pull the compartment door 203 and rotate it along the axis of the hinge shaft 204. At this time, the cantilever electric control compartment 201 is in an open state, which is convenient for construction personnel to inspect or control the circuit board 219 and core electrical. When the control compartment door 203 rotates along the axis of the hinge shaft 204 and the cantilever electric control compartment 201 is in a closed state, the sealing gasket prevents external air from entering the interior from the edge where the compartment door 203 contacts the cantilever electric control compartment 201, thereby playing a sealing role, thereby protecting the circuit structure and electrical components in the circuit board 219 and avoiding power outages or fires caused by external impacts.

[0029] like Figure 8As shown, when the annular electromagnet 222 is in a powered-on state and the annular electromagnet 222 is set to the N pole, the sealing plate 221 moves from the inside to the outside inside the exhaust groove, and the second compression spring 220 is in a stretched state. When the annular electromagnet 222 is in a powered-on state and the annular electromagnet 222 is set to the S pole, the sealing plate 221 moves from the outside to the inside of the exhaust groove, and the second compression spring 220 is in a compressed state.

[0030] When in use, an annular electromagnet 222 and a sealing plate 221 are arranged in the exhaust slot, and a second magnetic block and a first compression spring 213 are respectively arranged at the bottom of the sealing plate 221. In this way, the annular electromagnet 222 is controlled to release the corresponding magnetic force to control the sealing block to move up and down along the inner wall of the exhaust slot. When the sealing block moves out of the exhaust slot, the gas in the cantilever electric control compartment 201 can be discharged to the outside from the exhaust slot in conjunction with the exhaust fan 216. When the annular electromagnet 222 is controlled to control the sealing block to move to the inside of the exhaust slot and restore the initial state, the gas in the cantilever electric control compartment 201 cannot be discharged to the outside through the exhaust slot.

[0031] like Figure 5 As shown, filter holes are provided on the surfaces of the first filter plate 208 and the second filter plate 209, and the shapes of the filter holes on the first filter plate 208 and the second filter plate 209 are both set to be D-shaped. The shapes of the filter holes on the first filter plate 208 and the second filter plate 209 are staggered, and a sealing area is formed when the first filter plate 208 and the second filter plate 209 overlap with each other.

[0032] When in use, D-shaped sieve holes are set on the first filter plate 208 and the second filter plate 209, and the sieve holes on the first filter plate 208 and the second filter plate 209 are staggered. In this way, the electromagnet on the first filter plate 208 releases the corresponding electromagnetic force to control the first magnetic block so that the first filter plate 208 and the second filter plate 209 overlap with each other and form a sealed area. At this time, the gas outside the cantilever electric control cabin 201 cannot enter the cantilever electric control cabin 201 through the pipeline 207 and the ventilation slot 202.

[0033] like Figure 1 and Figure 2As shown, the present invention also provides a telescopic arm of a crane, comprising an electrically controlled adjustment component and a telescopic arm body 1, the telescopic arm body 1 comprising a support plate 102, a steering shaft 103 is provided on the upper surface of the support plate 102, and a first telescopic arm 101 is hingedly provided at the top end of the steering shaft 103, the electrically controlled adjustment component is fixed to the upper surface of the first telescopic arm 101, the steering shaft 103 is rotatably connected to the surface of the support plate 102, a second telescopic arm 105 is movably provided inside the first telescopic arm 101, and a third telescopic arm 106 is movably provided inside the second telescopic arm 105, and a sling 107 is provided at one end of the third telescopic arm 106 away from the second telescopic arm 105, a hydraulic rod 104 is provided at one end of the steering shaft 103 close to the first telescopic arm 101, and an end of the hydraulic rod 104 away from the first telescopic arm 101 is movably arranged on the side of the steering shaft 103.

[0034] When in use, first install the support plate 102 on the construction site, and connect the support plate 102 with the transmission circuit to ensure that the transmission circuit can supply power to the telescopic arm body 1, so that the telescopic arm body 1 can perform construction operations. In addition, according to the construction environment, the steering shaft 103 is used to rotate the angle on the top of the support plate 102, so as to control the construction angles of the first telescopic arm 101, the second telescopic arm 105 and the third telescopic arm 106 to complete the construction operation. Then, the required construction height and length are determined according to the construction environment, and the second telescopic arm 105 and the third telescopic arm 106 are reasonably dispatched by the hydraulic rod 104. 6 is used to lift and move the workpiece that needs to be moved. In addition, a cantilever electric control compartment 201 is arranged above the first telescopic arm 101, so that during the construction process of the crane telescopic arm body 1, the control system in the cantilever electric control compartment 201 can be used to accurately control the telescopic length of the crane telescopic arm body 1. In addition to controlling the telescopic length, the cantilever electric control compartment 201 can also adjust the telescopic speed of the crane telescopic arm body 1, and the electronic control system (circuit board 219) in the cantilever electric control compartment 201 can detect the working status of the crane telescopic arm body 1 in real time, thereby improving the safety during construction operations.

[0035] During use, although ventilation slots 202 and pipes 207 are arranged opposite to each other on the two sides of the cantilever electric control compartment 201, external air enters the cantilever electric control compartment 201 from the ventilation slots 202 and pipes 207 on one side and is discharged to the outside through the ventilation slots 202 and pipes 207 on the other side to form convection, thereby achieving heat dissipation of the circuit board 219 inside the cantilever electric control compartment 201. However, due to long-term use at the construction site, dust particles and impurities in the air in the construction area will enter the cantilever electric control compartment 201. Although the first filter plate 208 and the second filter plate 209 in the pipeline 207 can timely intercept and filter the dust particles and impurities in the gas, the filtered dust particles and impurities will accumulate beside the first filter plate 208, affecting the air intake. In addition, affected by the wind force and the volume of the dust particles, when the dust particles are close to the diameter of the sieve holes on the first filter plate 208 and the second filter plate 209, they are prone to get stuck or congested at the outer sieve holes of the first filter plate 208, thereby affecting the overall heat dissipation efficiency of the cantilever electric control cabin 201.

[0036] At the same time, during the construction process, water spraying or watering is usually used to suppress the generation of dust. In this process, some air contains highly humid gases and enters the interior of the cantilever electric control compartment 201, which will damage the circuit board 219 inside the cantilever electric control compartment 201. Although the desiccant can absorb moisture in the air during this process, there is an upper limit to the adsorption degree of the desiccant. Once the desiccant is in a saturated state, it cannot continue to absorb moisture in the cantilever electric control compartment 201, thereby causing damage to the circuit board 219 in the cantilever electric control compartment 201. Based on this, the following control plan is made: By using flow sensors installed inside the pipes 207 on the left and right sides of the cantilever electric control chamber 201, the gas flow data entering the cantilever electric control chamber 201 is detected and recorded. When dust particles and impurities accumulate or clog the first filter plate 208 and the second filter plate 209, the gas flow data in the pipe 207 will decrease.

[0037] When the flow sensor detects that the flow in the pipeline 207 is above the preset value, it means that there is no blockage or jamming on the surface and the sieve holes of the first filter plate 208 and the second filter plate 209. Without making any adjustments, air convection is used to achieve the effect of cooling the interior of the cantilever electric control cabin 201.

[0038] When the flow sensor detects that the flow rate in the pipe 207 is lower than the preset value, it means that the first filter plate 208 and the second filter plate 209 are in a slightly blocked state. At this time, the micro motor in the electromagnetic slider 223 is controlled to rotate, and the sliding plate 205 is driven to rotate along the axis of the micro motor. At this time, the first filter plate 208 and the second filter plate 209 rotate together with the sliding plate 205, and the sliding plate 205, the first filter plate 208 and the second filter plate 209 are controlled to rotate to 90 degrees. Then, the electromagnet on the second filter plate 209 drives the first filter plate 208 to rotate. The first magnetic block on the plate 208 releases the magnetic attraction, so that the first filter plate 208 moves toward the second filter plate 209. When the first filter plate 208 and the second filter plate 209 contact and collide with each other, the dust particles blocked on the first filter plate 208 are discharged toward the first filter plate 208 close to the inner wall of the pipe 207 by the impact generated by the collision, and the dust particles blocked on the sieve holes of the second filter plate 209 are directly discharged after being impacted and stagnate on the surface of the second filter plate 209 under the action of gravity, and then the control The annular electromagnet 222 generates a magnetic repulsion force on the second magnetic block, so that the sealing plate 221 moves toward the top in the exhaust slot. When the sealing plate 221 moves out of the exhaust slot, the external gas is connected to the inside of the cantilever electric control chamber 201 through the ventilation slot 202, and then the drive motor is turned on to control the exhaust fan 216 to rotate, so that the gas is sucked out from the exhaust slot into the inside. At this time, the gas will flow from top to bottom at the top of the cantilever electric control chamber 201 and be discharged outward through the ventilation slots 202 and pipes 207 on the left and right sides of the cantilever electric control chamber 201. The dust particles thus cleaned out will not enter the interior of the cantilever electric control cabin 201, and the blown wind will discharge the dust attached to the surface of the second filter plate 209 and the dust discharged from the first filter plate 208 on the inner wall of the pipe 207 to the outside. Since the first filter plate 208 and the second filter plate 209 overlap with each other, the dust particles will not be between the first filter plate 208 and the second filter plate 209, thereby completing the clearing of the sieve holes on the first filter plate 208 and the second filter plate 209 to avoid long-term blockage affecting the heat dissipation efficiency.

[0039] After the above adjustment, if the flow sensor detects that the flow in the pipeline 207 increases but is still lower than the preset value, it means that the dust particles and impurities in the sieve holes of the first filter plate 208 and the second filter plate 209 are in a serious blockage state. At this time, the exhaust fan 216 is still controlled by the drive motor to suck the gas from the outside to the inside of the cantilever electric control warehouse 201, and the first filter plate 208 and the second filter plate 209 that are not in a blocked state on one side of the cantilever electric control warehouse 201 are controlled to fit together to form a sealing area by the cooperation of the electromagnet and the first magnetic block. Then, the electromagnetic slider 223 is controlled to slide back and forth inside the pipeline 207 on the first electromagnetic slide rail, so that the gas in the cantilever electric control warehouse 201 is in a pulsed manner and impacts the first filter plate 208 and the second filter plate 209 that are blocked on the other side of the cantilever electric control warehouse 201. At this time, the gas in the cantilever electric control warehouse 201 is only discharged to the ventilation slot 202 and the pipe 207 on the blocked side of the cantilever electric control warehouse 201, so as to clean the dust particles and impurities that are seriously blocked on the sieve holes of the first filter plate 208 and the second filter plate 209. In addition, during the cleaning process, when it is necessary to clean the first filter plate 208 near the outlet of the pipe 207, it is only necessary to first use the mutual cooperation of the electromagnet and the first magnetic block to make the first filter plate 208 and the second filter plate 209 overlap with each other, and then use the micro motor on the first sliding block to control the sliding plate 205, the first filter plate 208 and the second filter plate 209 to rotate 180°, so that the first filter plate 208 will switch positions with the second filter plate 209, so as to further clean the dust particles and impurities blocked on the first filter plate 208.

[0040] In order to prevent the air humidity entering the cantilever electric control chamber 201 from being high, a regeneration desiccant is filled above the load-bearing plate, and the regeneration desiccant is used to absorb the moisture in the air entering the cantilever electric control chamber 201, so that the cantilever electric control chamber 201 is always kept dry. At the same time, a humidity sensor is built into the bottom of the heat conducting plate 210, so that the humidity data of the regeneration desiccant on the load-bearing plate can be monitored and recorded in real time by the humidity sensor. The data detected by the humidity sensor can be used to determine whether the regeneration desiccant is in a saturated state. The specific steps are as follows: When the humidity sensor detects that the humidity data of the regenerated desiccant is within the preset value, it means that the regenerated desiccant is not in a saturated state and can continue to absorb moisture in the gas in the cantilever electric control cabin 201 without any processing and continues to absorb moisture in the gas normally.

[0041] When the humidity sensor detects that the humidity data of the regenerated desiccant is higher than the preset value, it means that the regenerated desiccant is in and close to a saturated state. At this time, the annular electromagnet 222 is first used to control the sealing block to slide from the inside of the exhaust slot to the outside, and the sealing block slides out of the cantilever electric control chamber 201, so that the top gas can enter the inside of the cantilever electric control chamber 201 through the space between the exhaust slot and the sealing block. At the same time, the driving motor is used to control the exhaust fan 216 to start working, so that the gas is discharged from the inside of the cantilever electric control chamber 201 through the exhaust slot and the sealing plate 221 to the outside. When the driving motor controls the exhaust fan 216 to move, the cantilever electric control chamber 201 will suck the external gas into the cantilever electric control chamber 201 through the ventilation slots 202 and the pipes 207 on the left and right sides, and pass the gas through the movable filter plate 2 12 and the exhaust rod enter the upper layer of the heat conducting plate 210, and are discharged to the outside through the space between the exhaust groove and the sealing plate 221, and then the heating module 215 is turned on, and the heat generated by the heating module 215 is transferred to the heat conducting plate 210, and the heat conducting characteristics of the heat conducting plate 210 itself are used to directly heat the regeneration desiccant on the load-bearing plate. In this process, since the working mode of the exhaust fan 216 is to inhale air from the left and right ventilation grooves 202 of the cantilever electric control cabin 201 and discharge it to the outside through the exhaust groove on the top, the heat generated by the heating module 215 will not be transferred to the circuit board 219 in the cantilever electric control cabin 201 and cause damage to the circuit board 219. During the heating process, the heat is stagnated in the regeneration desiccant on the load-bearing plate, so that the regeneration desiccant is always in a desorption state.

[0042] After the above adjustment, if the humidity sensor detects that the humidity data of the regenerated desiccant has decreased but is still higher than the preset value, it means that the regenerated desiccant is adsorbed together due to being in a saturated state, and the internal regenerated desiccant cannot be heated evenly, resulting in uneven desorption of the regenerated desiccant by the heating module 215. At this time, the annular electromagnet 222 is controlled to control the sealing plate 221 to move to the inside of the exhaust slot, so that the external air cannot pass through the sealing plate 221 and the exhaust slot into the cantilever electric control compartment 201. Then, the first filter plate 208 and the second filter plate 209 on the left and right sides of the cantilever electric control compartment 201 are controlled to fit together with the first magnetic block through the electromagnet. Since the sieve holes on the first filter plate 208 and the second filter plate 209 are in a D-shape, and the sieve holes on the first filter plate 208 and the second filter plate 209 are staggered, the fitted first filter plate 208 and the second filter plate 209 will be in a sealed state. When the first filter plates 208 on the left and right sides of the cantilever electric control compartment 201 are fitted with the first filter plates 208 and the second filter plates 209, the air will not be trapped in the cantilever electric control compartment 201. After the two filter plates 209 are attached to each other, the entire cantilever electric control chamber 201 is in a completely closed state. At this time, the first sliding blocks on both sides of the cantilever electric control chamber 201 are respectively controlled to make the overlapped first filter plate 208 and the second filter plate 209 move toward the inside of the cantilever electric control chamber 201. Since the cantilever electric control chamber 201 is in a sealed state at this time, when the two overlapped first filter plates 208 and the second filter plates 209 move, the pressure inside the cantilever electric control chamber 201 will increase. At this time, the movable filter plate 212 will be pressed and move along the inside of the dehumidification chamber 218 toward the heat conducting plate 210, so that the regenerated desiccant between the heat conducting plate 210 and the movable filter plate 212 will be squeezed and dispersed. At this time, the heating module 215 is continued to be turned on to uniformly heat and desorb the dispersed regenerated desiccant through the heat conducting plate 210, and at the same time, the electromagnet and the first magnetic block are used to separate the first filter plate 208 and the second filter plate 209 from each other, and the annular electromagnet 222 is controlled to move the sealing plate 221 out of the exhaust slot.

[0043] It is worth noting that the regeneration desiccant used in this solution is silica gel desiccant, and after silica gel absorbs water, it can be removed by thermal desorption. When the water content of the regenerated silica gel is generally controlled below 2%, it can be put into use again, which is quick and convenient. In addition, the edges of the first filter plate 208 and the second filter plate 209 close to the inner wall of the pipe 207 are sealed with silica gel material, and the diameters of the first filter plate 208 and the second filter plate 209 are smaller than the inner diameter of the pipe 207. When the sliding plate drives the overlapped first filter plate and the second filter plate to rotate, there will be no motion interference with the pipe. In addition, the first filter plate and the second filter plate are perpendicular to the pipe (the initial state of the first filter plate and the second filter plate, please refer to the specific Figure 4 or Figure 5 ) inner wall, the edges of the first filter plate and the second filter plate completely fit the inner wall of the pipe, and no gap will be generated to cause air containing dust particles to directly enter the interior of the cantilever electric control cabin 201.
