Description

Technical Field

[0001] This invention relates to the field of underground coal mine transportation, specifically an automatic leveling mine belt support. Background Technology

[0002] Over 80% of my country's coal resources are buried at depths exceeding 300 meters, with underground mining accounting for a significant portion. Currently, underground mining in my country primarily utilizes the longwall retreat mining method, and coal mined from the face is transported to the hoisting shaft via conveyor belts.

[0003] The conveyor belt is located in a dedicated roadway. Over time and with increasing mining stress, the roadway will deform, especially the floor. Currently, the belt supports are placed directly on the roadway floor. Floor deformation can cause the support legs to lift or sink in certain areas, resulting in unevenness in the belt supports. Unevenness can lead to coal spillage or belt slippage during transport, ultimately causing disruptions to the conveyor system. Therefore, ensuring the flatness of the conveyor belt system is of great importance for efficient operation and safe production.

[0004] Currently, during belt conveyor transport, if the tunnel floor bulges, the method to ensure the stability of the conveyor belt is manual adjustment. This manual adjustment requires stopping the conveyor belt; using jacks to raise the belt and create space for work; then, workers use shovels, pickaxes, or pneumatic drills to level the deformed tunnel floor; finally, the conveyor belt is lowered and operation resumes. This method is time-consuming, labor-intensive, and disrupts transport.

[0005] The aforementioned problems represent the actual situation encountered by all on-site maintenance personnel. When the geological conditions of the tunnel floor are poor, deformation may occur again after repair, requiring repeated work. During the grounding process, the conveyor belt system is forced to stop operating, interrupting mine production and preventing the mined coal and rock from being brought to the surface, resulting in significant losses. It is well known that coal mine tunnels are narrow, humid, and have high coal dust concentrations, creating a harsh working environment. Using existing leveling methods requires workers to repeatedly move through the equipment, and long-term maintenance can lead to occupational diseases such as lumbar disc herniation. The cumbersome nature of conveyor belt leveling remains unresolved, resulting in low transportation efficiency, wasted manpower, and a lack of satisfactory results.

[0006] To address the aforementioned issues, the invention with application number 2013208790358 provides a novel belt conveyor support. This belt conveyor support includes a support connector, a base component, and a distance adjustment device for adjusting the distance between the support connector and the base component. It adopts a hinged connection method, and the height of the belt conveyor support can be adjusted by manually moving the slider in the distance adjustment device. However, the rotation gap at the hinge cannot be completely sealed, and high-concentration coal dust in the mine can easily enter through the gap, thereby reducing its flexibility, shortening its service life, requiring regular replacement, affecting work efficiency, and increasing operating costs.

[0007] The invention with application number 2020232999693 provides an adaptive adjustment device for a ground-mounted conveyor belt support, including support legs and an adjustment device, which realizes the free adjustment of the height of the ground-mounted material conveyor belt support. The whole device is simple, convenient and easy to operate, but it requires manual rotation of the bolt rod in the adjustment device for adjustment, and it cannot detect whether the belt height has deviated, requiring manual detection, which is time-consuming and labor-intensive.

[0008] Related research and improvements are also underway. Summary of the Invention

[0009] The purpose of this invention is to provide an automatic leveling conveyor belt support for mining, so as to solve the problems mentioned in the background art.

[0010] To achieve the above objectives, the present invention provides the following technical solution: an automatic leveling mine belt conveyor support, comprising an automatic balance adjustment system 1, a belt frame system 2, a belt support system 3, and a self-balancing measurement system 4; the automatic balance adjustment system 1, as the lower part of the mine belt conveyor support, can automatically adjust the height of the invention according to the deformation of the roadway floor to maintain balance; the belt frame system 2, located in the middle of the mine belt conveyor support, is the main structural component of the invention and provides support for the stability of the mine belt conveyor support; the automatic balance adjustment system 1 is located below the belt frame system 2, and the four corner points above the belt frame system 2 can provide installation positions for the self-balancing measurement system 4. The belt support system 3 is installed on the belt frame system 2, providing support for the conveying of the belt. The self-balancing measurement system 4, installed at the four corner points above the belt frame system 2, is the core system of the invention, capable of detecting and identifying the flatness of the belt device and transmitting signals to the automatic balance adjustment system 1; the self-balancing measurement system 4 can also be automatically cleaned.

[0011] As a further embodiment of the present invention: the automatic balance adjustment system 1 includes an adaptive support base 11, a vertical lifting support column 12, a vertical lifting column 13, a lifting column locker 14, a lifting column locking tongue 15, a motor gear integrated device 16, a wire 17, and a drive module 18.

[0012] The adaptive support base 11 is made of stainless steel and is connected to the vertical lifting support column 12. Its internal space can fit with the vertical lifting support column 12. The adaptive support base 11 includes a ball joint structure on the top and is connected to the bottom of the vertical lifting support column 12. The adaptive support base 11 can automatically adjust and adapt according to the flatness of the ground.

[0013] The vertical lifting support column 12 is made of stainless steel and is cylindrical. It is connected to the vertical lifting column 13 at the top and to the adaptive support base 11 at the bottom.

[0014] The vertical lifting column 13 is made of alloy steel and has a semi-cylindrical structure. It has meshing teeth on the outside and can be integrated with a motor gear integrated device 16 at its upper end, and can move linearly up and down. Its lower end is connected to the vertical lifting support column 12. The vertical lifting column 13 can be raised and lowered under the drive of the motor gear integrated device 16 and can withstand a large radial load to provide support for the belt frame system 2.

[0015] The lifting column lock 14 adopts an electromagnetic attraction structure and has an overall cuboid structure. Its upper part is connected to the motor gear integration device 16, and its side is provided with a spring 141, which is connected to the lifting column locking tongue 15. The lifting column lock 14 is used to control the movement of the lifting column locking tongue 15 through a magnetic field. When the motor gear integration device 16 is working, the lifting column lock 14 generates a magnetic field. Under the action of the magnetic force, the lifting column locking tongue 15 compresses the spring 141 and moves towards the lifting column lock 14, thereby separating from the meshing teeth on the vertical lifting column 13, releasing the lock on the vertical lifting column 13, and allowing the vertical lifting column 13 to move linearly up and down under the drive of the motor gear integration device 16. When the motor gear integration device 16 stops working, the magnetic field disappears, the spring 141 releases its elastic potential energy and pushes the lifting column locking tongue 15 to reset, so that the lifting column locking tongue 15 re-meshes and locks with the meshing teeth on the vertical lifting column 13, thereby restricting the movement of the vertical lifting column 13 and keeping it in its current position.

[0016] The lifting column locking tongue 15 is made of low-carbon steel and has good magnetic conductivity. It has a rectangular structure and one side engages with the meshing teeth on the vertical lifting column 13. The other side is connected to the lifting column locker 14. When the motor gear integrated device 16 is working, the lifting column locking tongue 15 moves away from the vertical lifting column 13 under the control of the lifting column locker 14 to release the lock on the vertical lifting column 13. When the motor gear integrated device 16 stops working, the lifting column locking tongue 15 approaches the vertical lifting column 13 and engages with its meshing teeth to lock and restrict the movement of the vertical lifting column 13.

[0017] The outer shell of the motor-gear integrated device 16 is made of carbon steel and has an overall rectangular structure. A wire 17 is connected to the side of the device closest to the drive module 18. The side of the motor-gear integrated device 16 is connected to the intersection of the belt frame longitudinal beam 21 and the belt frame cross beam 22, specifically located on the outer side of the intersection. The lower part is connected to the lifting column lock 14. A semi-circular sliding track 164 is provided in the middle of the motor-gear integrated device 16. The sliding track 164 covers the vertical lifting column 13, allowing the vertical lifting column 13 to move linearly within the sliding track 164. The motor-gear integrated device 16 is an integrated transmission mechanism consisting of a high-torque motor 161, a pinion 162, a large gear 163, and the sliding track 164. After the high-torque motor 161 outputs power, it drives the pinion 162 to rotate. The pinion 162 further drives the large gear 163 to rotate. The large gear 163 is connected to the vertical lifting column 13, thereby achieving the linear lifting movement of the vertical lifting column 13 through the rotation of the large gear 163. When the pinion 162 rotates clockwise, it drives the vertical lifting column 13 to move upward, thereby lowering the height of the support for leveling; when the pinion 162 rotates counterclockwise, it drives the vertical lifting column 13 to move downward, thereby raising the height of the support for leveling.

[0018] The wire 17 is composed of a high-specification conductor core and an outer insulation layer, and has an overall cylindrical structure. One end is connected to the drive module 18, and the other end is connected to the motor gear integrated device 16. It is used to supply power to the motor gear integrated device 16 to control the high-torque motor 161 and the lifting column lock 14.

[0019] The drive module 18 is encased in stainless steel, which is corrosion-resistant. It is cube-shaped and connected to the conductor 17 at the bottom. Its side is attached to the longitudinal beam 21 of the belt frame. It can receive signals from the self-balancing measurement and communication module 401, control the current flow of the conductor 17, and transmit the current through the conductor 17 to the motor gear integration device 16. The motor gear integration device 16 adjusts the linear movement of the vertical lifting column 13 to balance the belt frame system.

[0020] As a further embodiment of the present invention: the belt frame system 2 includes a belt frame longitudinal beam 21, a belt frame cross beam 22, and a belt frame reinforcing rod 23.

[0021] The belt frame longitudinal beams 21 are made of alloy steel. Both ends of the two belt frame longitudinal beams 21 are connected to the two belt frame crossbeams 22, forming the belt frame. The outer side of the middle section of the belt frame longitudinal beams 21 along its length is connected to the drive module 18, while the outer sides of both ends along its length are connected to the self-balancing measurement system 4 and the motor gear integration device 16. The lower side of the belt frame longitudinal beams 21 is connected to the lower side plate 34 of the belt support and is reinforced and fixed to the motor gear integration device 16 via belt frame reinforcing rods 23. The upper side is connected to the long frame plate 31 of the belt support. The belt frame longitudinal beams 21 are used to bear and support the overall structure, capable of transmitting the vertical load of the belt and distributing the load evenly. Their regular shape provides installation positions for other accessories.

[0022] The belt frame crossbeam 22 is made of alloy steel and its two ends are connected to the belt frame longitudinal beam 21 along its length. The two ends of the belt frame crossbeam 22 are connected to the motor gear integration device 16. The belt frame crossbeam 22 connects the two belt frame longitudinal beams 21 to prevent them from becoming unstable and deformed, and to distribute the load evenly so that the belt frame system 2 forms a stable structure.

[0023] The belt frame reinforcing rod 23 is made of alloy steel and has an overall cylindrical structure. Its upper end is connected to the belt frame longitudinal beam 21, and its lower end is connected to the motor gear integration device 16. The belt frame reinforcing rod 23 supports the belt frame system by forming a triangular stable structure with related components, thereby improving the stability of the overall structure.

[0024] As a further embodiment of the present invention: the belt support system 3 includes a belt support long frame plate 31, a belt support outer side plate 32, a belt support inner side plate 33, a belt support lower side plate 34, a belt upper idler roller 35, and a belt lower idler roller 36.

[0025] The belt support long frame plate 31 is made of alloy steel, has a cuboid shape, and is welded to the belt frame longitudinal beam 21. It is also welded to the belt support outer side plate 32 and belt support inner side plate 33. It mainly provides support for the upper belt support outer side plate 32 and belt support inner side plate 33.

[0026] The outer side plate 32 of the belt support is made of alloy steel and has a cuboid shape. It is welded to the long frame plate 31 of the belt support at the bottom. The inner side of the outer side plate 32 of the belt support can be used to install the belt upper roller 35, providing support and fixation for the belt upper roller 35.

[0027] The inner side plate 33 of the belt support is made of alloy steel and has a cuboid shape. It is welded to the long frame plate 31 of the belt support at the bottom. The belt upper roller 35 can be installed on the upper side plate 33 of the belt support, which mainly supports and fixes the belt upper roller 35.

[0028] The lower side plate 34 of the belt support is made of alloy steel and has a cuboid shape. It is welded to the longitudinal beam 21 of the belt frame at the top and connected to the lower belt roller 36 between the two lower side plates. It is mainly used to fix the lower belt roller 36 and prevent the belt from shifting.

[0029] The belt idler roller 35 is made of alloy steel, has a strong load-bearing capacity, and is U-shaped. It is composed of three idlers and mainly serves to support the belt and prevent the belt from running off-center. The belt idler roller 35 is hinged to the outer side plate 32 of the belt support on both sides and the inner side plate 33 of the belt support on the lower side. This can increase the material loading capacity, and at the same time, it can roll around its own axis and reduce the friction of the belt, ensuring safe and efficient operation.

[0030] The belt lower idler roller 36 is made of alloy steel and is a single cylindrical flat roller. It is connected to the belt support lower side plate 34 by a pin-type hinge on both sides. It can roll around its own axis to reduce the friction of the belt and support the return belt.

[0031] As a further embodiment of the present invention: the self-balancing measurement system 4 includes a self-balancing measurement communication module 401, a support base 402, a self-balancing hemispherical gimbal 403, a laser detection module 404, a dustproof shell 405, a rotating dust removal swing arm 406, a rotating shaft 407, an atomizing nozzle 408, a cleaning rotating motor 409, a booster pump 410, a water storage tank 411, a water suction pipe 412, a suction air pipe 413, a delivery pipe 414, and a wireless electromagnetic valve 415.

[0032] The self-balancing measurement and communication module 401 has a stainless steel casing to prevent corrosion. It is rectangular in shape, with its side connected to the belt frame longitudinal beam 21 and its top connected to the support base 402. Its main function is to wirelessly receive the leveling signal from the laser detection module 404. After receiving the signal, it completes data calculation and leveling strategy planning, and simultaneously sends precise execution commands to the drive module 18. Upon triggering the command, the wire 17 is energized, and the drive module 18, in conjunction with the motor gear integrated device 16, precisely controls the extension and retraction of the vertical lifting column 13 through gear rotation. After the vertical lifting column 13 has completed its adjustment, the current in the wire 17 is interrupted, and the gears, after leveling, drive the laser detection module 404 again for retesting to ensure balance. Additionally, the external belt frame longitudinal beam 21 provides installation space for the self-balancing measurement and communication module 401 and prevents obstruction.

[0033] The outer shell of the support base 402 is made of stainless steel to prevent corrosion. It is rectangular in shape, with the lower part connected to the self-balancing measurement and communication module 401, and the upper part embedded with a self-balancing hemispherical gimbal 403. This protects the self-balancing hemispherical gimbal 403 and provides space for its rotation and automatic balancing. The self-balancing hemispherical gimbal 403 is made of stainless steel and is hemispherical. The hemispherical shape of the self-balancing hemispherical gimbal 403 fits the support base 402.

[0034] The self-balancing hemispherical gimbal 403 uses wear-resistant bushings on its lower rotating parts, and a laser detection module 404 is installed on the upper part of the hemisphere. The self-balancing hemispherical gimbal 403 can automatically level itself above the support base 402. The self-balancing hemispherical gimbal 403 contains a cleaning rotation motor 409, a booster pump 410, a water tank 411, a water suction pipe 412, a suction pipe 413, a delivery pipe 414, and a wireless electromagnetic valve 415. The self-balancing hemispherical gimbal 403 also contains a gyroscope and an accelerometer, which can sense angular velocity and the direction of gravity.

[0035] The laser detection module 404 is made of stainless steel, is cubic in shape, and is mounted on a self-balancing hemispherical gimbal 403, with a rotating shaft 407 passing through its center. Several laser emitters are located on the sides of the laser detection module 404. These laser detection modules 404 can communicate and identify each other, calculating the high or low position of a particular laser module and generating adjustment commands. The laser detection module 404 transmits these commands from the self-balancing measurement and communication module 401 to the drive module 18 for execution. The laser emitters are mainly used for laser emission focusing; if a deviation occurs, the laser detection module 404 will detect it and make corresponding adjustments. In addition, the laser detection module 404 can control the start of the cleaning rotation motor 409, the booster pump 410, and its wireless electromagnetic valve 415. When the laser emitter detects that there is a lot of dust on the surface of the dustproof housing 405, which blocks the transmission of the laser signal, the laser detection module 404 starts an emergency cleaning operation. The laser detection module 404 will control the cleaning rotation motor 409, the booster pump 410, and the wireless electromagnetic valve 415 to clean and dry the dustproof housing 405. The laser detection module 404 is equipped with a timing device inside, and the timed cleaning interval can be set through the laser detection module 404, such as thirty minutes, sixty minutes, ninety minutes, etc.

[0036] The dustproof housing 405 is made of polycarbonate, which is transparent, has good impact resistance, and can be repeatedly cleaned by high-pressure water. It is shaped like a hemispherical cover with a seamless curved surface, making it easy to clean dust accumulation. The dustproof housing 405 encloses and protects the laser detection module 404 inside, and the outside is a rotating dust removal arm 406, which is connected to the central rotating shaft 407. The main function of the dustproof housing 405 is to prevent dust from blocking laser emission and to isolate external moisture and other effects, thus extending the service life of the laser detection module 404.

[0037] The rotating dust-collecting arm is made of 406 stainless steel, semi-circular in shape, hollow inside, and connected to a rotating shaft 407 at its center. The rotating shaft 407 drives the rotating dust-collecting arm 406 to rotate. During the rotation of the rotating dust-collecting arm 406, the booster pump 410 works simultaneously to complete water spraying cleaning and air drying. Several atomizing nozzles 408 are evenly arranged on the inner side of the rotating dust-collecting arm 406, precisely pointing towards the dustproof outer shell 405 to achieve comprehensive coverage. The interior of the rotating dust-collecting arm 406 serves as a channel for high-pressure water and drying air.

[0038] The rotating shaft 407 is made of stainless steel and has a cylindrical structure with a hollow internal structure, serving as a channel for high-pressure water and drying air. The rotating shaft 407 passes through the center of the laser detection module 404 and the center of the dustproof shell 405, and is connected to the bottom of the cleaning rotating motor 409 inside the self-balancing hemispherical gimbal 403. The bottom of the rotating shaft 407 is connected to the delivery pipe 414, and the upper side of the rotating shaft 407 is connected to the rotating dust removal swing arm 406. The interior of the rotating shaft 407 is completely connected to the interior of the rotating dust removal swing arm 406, which not only enables the overall rotation through the cleaning rotating motor 409, but also provides a channel for the high-pressure water and drying air transmitted by the booster pump 410.

[0039] The atomizing nozzle 408 is made of stainless steel and has a cubic structure. It is hollow inside and has spray holes on one side facing the surface of the dustproof housing 405. Several atomizing nozzles 408 are evenly arranged inside the rotating dust removal arm 406, precisely facing the dustproof housing 405, and can spray water and blow drying air. The cleaning rotating motor 409 is an ordinary electric motor with good waterproof sealing. It has a cylindrical structure and is installed in the self-balancing hemispherical gimbal 403, with the rotating shaft 407 passing through its center.

[0040] The cleaning rotary motor 409 provides power to the rotating shaft 407 and controls the rotation of the rotating shaft 407, thereby driving the rotating dust removal arm 406 to rotate; the cleaning rotary motor 409 is controlled and started by the laser detection module 404; the booster pump 410 is a waterproof electric booster pump 410, which has an overall cylindrical structure and is installed on the side of the water storage tank 411. It is externally connected to two wireless electromagnetic valves 415, which are respectively connected to the water suction pipe 412 and the air suction pipe 413.

[0041] The booster pump 410 is connected to the rotating shaft 407 via a delivery pipe 414; the booster pump 410 is started by the laser detection module 404.

[0042] The water storage tank 411 is made of stainless steel, has a cuboid shape, and is installed in the self-balancing hemispherical gimbal 403, adjacent to the booster pump 410. Its main function is to store water and provide a water source for the booster pump 410.

[0043] The water suction pipe 412 is a rubber steel wire hose with a circular shape. One end is connected to the wireless electromagnetic valve 415 of the water suction pipe 412, and the other end is placed at the bottom of the water storage tank 411.

[0044] The suction pipe 413 is a rubber steel wire hose with a circular shape. One end is connected to the wireless electromagnetic valve 415 of the suction pipe 413, and the other end passes through the self-balancing hemispherical gimbal 403 for easy air intake.

[0045] The delivery pipe 414 is a rubber steel wire hose with a circular shape. One end is connected to the booster pump 410, and the other end is connected to the bottom of the rotating shaft 407. It serves as a channel for water and drying air.

[0046] The wireless electromagnetic valve 415 is made of stainless steel, has a cuboid shape, and is connected to the booster pump 410. There are two wireless electromagnetic valves 415; specifically, one wireless electromagnetic valve 415 is connected to the water suction pipe 412, and the other wireless electromagnetic valve 415 is connected to the air suction pipe 413. The wireless electromagnetic valve 415 is controlled by the laser detection module 404 to realize the opening and closing functions.

[0047] The method for using an automatic leveling conveyor belt support in mining: This invention uses a laser detection module 404 as the core sensing component, equipped with a self-balancing hemispherical gimbal 403, a self-balancing measurement and communication module 401, and a drive module 18, to achieve automatic leveling of the conveyor belt support under roadway floor deformation. The specific steps are as follows: (i) In the initial state, when the tunnel floor is free from deformation and the flatness meets the benchmark requirements, all laser detection modules 404 maintain a horizontal calibration state, and each execution module is in a low-power standby mode. (ii) When the tunnel floor bulges, the support will shift. The self-balancing hemispherical gimbal 403 senses the flatness deviation in real time through the built-in sensing unit. Once the deviation signal is detected, the adaptive leveling program is immediately started. Through the leveling of the self-balancing hemispherical gimbal 403 itself, the laser detection module 404 mounted on it is ensured to be the same as the initial state, eliminating interference factors in the subsequent measurement process. (III) After the self-balancing hemispherical gimbal 403 is leveled, several laser detection modules 404 can communicate and identify each other, detect and calculate their own high or low position through the laser emitter, and form control commands; then, the laser detection module 404 transmits the formed control commands wirelessly to the self-balancing measurement and communication module 401 to provide data support for the subsequent leveling strategy formulation. (iv) The self-balancing measurement and communication module 401 is used to perform data calculation after receiving the control command and to send a leveling command to the drive module 18 simultaneously. After receiving the leveling command, the drive module 18 is used to supply power to the high torque motor 161 and the lifting column locker 14 in the motor gear integration device 16 through the wire 17. The lifting column locker 14 controls the lifting column locking tongue 15 to separate from the vertical lifting column 13. If the bracket at the corresponding position is too high, the high torque motor 161 drives the pinion 162 to rotate clockwise. If the bracket at the corresponding position is too low, the high torque motor 161 drives the pinion 162 to rotate counterclockwise, so as to accurately control the lifting stroke of the vertical lifting column 13, thereby achieving accurate compensation for the deformation deviation of the base plate. (v) After the vertical lifting column 13 is adjusted to the position, the high torque motor 161 stops rotating, and the lifting column locking device 14 controls the lifting column locking tongue 15 to lock tightly with the vertical lifting column 13. After locking, if the laser detection module 404 is on the same horizontal plane, the operation ends and each module returns to standby mode. If the laser detection module 404 is not on the same horizontal plane, repeat steps (iii-v) until the detection result meets the requirements.

[0048] The cleaning and drying of the automatic leveling mine belt conveyor support requires the coordinated operation of a rotating dust removal arm 406, a rotating shaft 407, an atomizing nozzle 408, a cleaning motor 409, a booster pump 410, and a water storage tank 411. It features both timed cleaning and emergency cleaning modes. The specific steps are as follows: Timed cleaning (the cleaning program starts automatically every 30 minutes according to the preset cycle). (1) The laser detection module 404 starts the timed cleaning operation according to the preset time interval. The wireless electromagnetic valve 415 connected to the water suction pipe 412 is opened, the wireless electromagnetic valve 415 connected to the air suction pipe 413 is closed, and the booster pump 410 is started. The water delivery path is: water storage tank 411 → water suction pipe 412 → booster pump 410 → delivery pipe 414 → rotating shaft 407 → rotating dust removal arm 406 → atomizing nozzle 408. The atomizing nozzle 408 sprays water onto the surface of the dustproof shell 405 and cleans it. (2) After step (1) is completed, the wireless electromagnetic valve 415 connected to the water suction pipe 412 is closed, the wireless electromagnetic valve 415 connected to the air suction pipe 413 is opened, and the booster pump 410 continues to run; the delivery path of the drying air is: air suction pipe 413 → booster pump 410 → delivery pipe 414 → rotating shaft 407 → rotating dust removal arm 406 → atomizing nozzle 408. The atomizing nozzle 408 sprays the drying air onto the surface of the dustproof shell 405 and dries it. (3) During the execution of steps (1) and (2), the cleaning rotating motor 409 drives the rotating shaft 407 to rotate, and the rotating shaft 407 drives the rotating dust removal arm 406 to rotate circumferentially, so as to achieve a complete coverage of the dustproof shell 405 without dead angles. (4) The laser detection module 404 stops the timed cleaning operation and starts the countdown for the next timed cleaning operation.

[0049] Emergency cleaning (the emergency cleaning function will be triggered when excessive dust or other reasons obstruct laser detection). (A) The laser detection module 404 starts the emergency cleaning operation. The wireless electromagnetic valve 415 connected to the water suction pipe 412 is opened, the wireless electromagnetic valve 415 connected to the air suction pipe 413 is closed, and the booster pump 410 is started. The water delivery path is: water storage tank 411 → water suction pipe 412 → booster pump 410 → delivery pipe 414 → rotating shaft 407 → rotating dust removal arm 406 → atomizing nozzle 408. The atomizing nozzle 408 sprays water onto the surface of the dustproof shell 405 and cleans it. (B) After the cleaning process is completed, the wireless electromagnetic valve 415 connected to the water suction pipe 412 is closed, the wireless electromagnetic valve 415 connected to the air suction pipe 413 is opened, and the booster pump 410 continues to run; the delivery path of the drying air is: air suction pipe 413 → booster pump 410 → delivery pipe 414 → rotating shaft 407 → rotating dust removal arm 406 → atomizing nozzle 408. The atomizing nozzle 408 sprays the drying air onto the surface of the dustproof housing 405 and dries it. (C) During the execution of steps (A) and (B), the cleaning motor 409 drives the rotating shaft 407 to rotate, and the rotating shaft 407 drives the rotating dust removal arm 406 to rotate circumferentially, so as to achieve complete coverage of the dustproof shell 405. (D) The laser emitter of the laser detection module 404 checks whether the dust on the surface of the dustproof housing 405 is clean. If it is clean, the emergency cleaning operation is stopped. If it is not clean, (A-D) is repeated. If the dust on the surface of the dustproof housing 405 is clean, the emergency cleaning operation is stopped.

[0050] Compared with the prior art, the beneficial effects of the embodiments of the present invention are: This invention uses a vertical lifting gear to provide high-precision linear motion guidance for the vertical lifting column. It has a large stroke and high precision. The belt balance is adjusted by the lifting of the gear to ensure its normal operation. The lifting column locking tongue can fix the vertical lifting column and ensure the overall strength of the belt support. It is made of stainless steel, which has strong corrosion resistance and a long service life.

[0051] This invention features a separate cleaning device with two cleaning modes. It can perform cleaning at preset intervals, and it also cleans by recognizing the degree of obstruction of the dustproof shell. Furthermore, the rotating dust removal arm can achieve thorough cleaning without any blind spots, and it also includes a drying function.

[0052] This invention uses laser detection to identify the flatness of the belt conveyor and can transmit the information. Its efficiency and accuracy are far superior to manual observation, which can reduce operating costs and improve production safety.

[0053] The leveling, measurement, height adjustment, cleaning, and re-measurement processes of this invention are all completed automatically. Once set, no manual on-site operation is required, resulting in a high degree of automation.

[0054] The rotating dust removal arm and rotating shaft of this invention can not only achieve cleaning without dead angles through rotation, but also adopt a hollow design inside, which is connected to the conveying pipe to provide channels for cleaning water and drying air, realizing dual use in one unit and saving material costs.

Detailed Implementation

[0072] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0073] An automatic leveling mine conveyor belt support includes an automatic balance adjustment system 1, a conveyor belt frame system 2, a conveyor belt support system 3, and a self-balancing measurement system 4, such as... Figure 1As shown; the automatic balancing adjustment system 1, as the lower part of the mine conveyor belt support, can automatically adjust the height of the invention according to the deformation of the roadway floor to maintain balance; the conveyor belt frame system 2, located in the middle of the mine conveyor belt support, is the main structural body of the invention and provides support for the stability of the mine conveyor belt support; the automatic balancing adjustment system 1 is located below the conveyor belt frame system 2, and the four corner points above the conveyor belt frame system 2 can provide installation positions for the self-balancing measurement system 4. The conveyor belt support system 3 is installed on the conveyor belt frame system 2 to provide support for the conveying of the conveyor belt. The self-balancing measurement system 4, installed at the four corner points above the conveyor belt frame system 2, is the core system of the invention, which can detect and identify the flatness of the conveyor belt and transmit signals to the automatic balancing adjustment system 1. The self-balancing measurement system 4 can also be automatically cleaned.

[0074] For ease of use, the automatic balance adjustment system 1 includes an adaptive support base 11, a vertical lifting support column 12, a vertical lifting column 13, a lifting column locker 14, a lifting column locking tongue 15, a motor gear integrated device 16, a wire 17, and a drive module 18, such as... Figure 9 As shown.

[0075] The adaptive support base 11 is made of stainless steel and is connected to the vertical lifting support column 12. Its internal space can fit with the vertical lifting support column 12. The adaptive support base 11 includes a ball joint structure on the top and is connected to the bottom of the vertical lifting support column 12. The adaptive support base 11 can automatically adjust and adapt according to the flatness of the ground.

[0076] The vertical lifting support column 12 is made of stainless steel and is cylindrical. It is connected to the vertical lifting column 13 at the top and to the adaptive support base 11 at the bottom.

[0077] The vertical lifting column 13 is made of alloy steel and has a semi-cylindrical structure. It has meshing teeth on the outside and can be integrated with a motor gear integrated device 16 at its upper end, and can move linearly up and down. Its lower end is connected to the vertical lifting support column 12. The vertical lifting column 13 can be raised and lowered under the drive of the motor gear integrated device 16 and can withstand a large radial load to provide support for the belt frame system 2.

[0078] The lifting column lock 14 adopts an electromagnetic attraction structure and has an overall cuboid structure. Its upper part is connected to the motor gear integration device 16, and its side is provided with a spring 141, which is connected to the lifting column locking tongue 15. The lifting column lock 14 is used to control the movement of the lifting column locking tongue 15 through a magnetic field. When the motor gear integration device 16 is working, the lifting column lock 14 generates a magnetic field. Under the action of the magnetic force, the lifting column locking tongue 15 compresses the spring 141 and moves towards the lifting column lock 14, thereby separating from the meshing teeth on the vertical lifting column 13, releasing the lock on the vertical lifting column 13, and allowing the vertical lifting column 13 to move linearly up and down under the drive of the motor gear integration device 16. When the motor gear integration device 16 stops working, the magnetic field disappears, the spring 141 releases its elastic potential energy and pushes the lifting column locking tongue 15 to reset, so that the lifting column locking tongue 15 re-meshes and locks with the meshing teeth on the vertical lifting column 13, thereby restricting the movement of the vertical lifting column 13 and keeping it in its current position.

[0079] The lifting column locking tongue 15 is made of low-carbon steel and has good magnetic conductivity. It has a rectangular structure and one side engages with the meshing teeth on the vertical lifting column 13. The other side is connected to the lifting column locker 14. When the motor gear integrated device 16 is working, the lifting column locking tongue 15 moves away from the vertical lifting column 13 under the control of the lifting column locker 14 to release the lock on the vertical lifting column 13. When the motor gear integrated device 16 stops working, the lifting column locking tongue 15 approaches the vertical lifting column 13 and engages with its meshing teeth to lock and restrict the movement of the vertical lifting column 13.

[0080] The outer shell of the motor-gear integrated device 16 is made of carbon steel and has an overall rectangular structure. A wire 17 is connected to the side of the device closest to the drive module 18. The side of the motor-gear integrated device 16 is connected to the intersection of the belt frame longitudinal beam 21 and the belt frame cross beam 22, specifically located on the outer side of the intersection. The lower part is connected to the lifting column lock 14. A semi-circular sliding track 164 is provided in the middle of the motor-gear integrated device 16. The sliding track 164 covers the vertical lifting column 13, allowing the vertical lifting column 13 to move linearly within the sliding track 164. The motor-gear integrated device 16 is an integrated transmission mechanism consisting of a high-torque motor 161, a pinion 162, a large gear 163, and the sliding track 164. After the high-torque motor 161 outputs power, it drives the pinion 162 to rotate. The pinion 162 further drives the large gear 163 to rotate. The large gear 163 is connected to the vertical lifting column 13, thereby achieving the linear lifting movement of the vertical lifting column 13 through the rotation of the large gear 163. When the pinion 162 rotates clockwise, it drives the vertical lifting column 13 to move upward, thereby lowering the height of the support for leveling; when the pinion 162 rotates counterclockwise, it drives the vertical lifting column 13 to move downward, thereby raising the height of the support for leveling.

[0081] The wire 17 is composed of a high-specification conductor core and an outer insulation layer, and has an overall cylindrical structure. One end is connected to the drive module 18, and the other end is connected to the motor gear integrated device 16. It is used to supply power to the motor gear integrated device 16 to control the high-torque motor 161 and the lifting column lock 14.

[0082] The drive module 18 is encased in stainless steel, which is corrosion-resistant. It is cube-shaped and connected to the conductor 17 at the bottom. Its side is attached to the longitudinal beam 21 of the belt frame. It can receive signals from the self-balancing measurement and communication module 401, control the current flow of the conductor 17, and transmit the current through the conductor 17 to the motor gear integration device 16. The motor gear integration device 16 adjusts the linear movement of the vertical lifting column 13 to balance the belt frame system.

[0083] Furthermore, the belt frame system 2 includes belt frame longitudinal beams 21, belt frame crossbeams 22, and belt frame reinforcing bars 23.

[0084] The belt frame longitudinal beams 21 are made of alloy steel. Both ends of the two belt frame longitudinal beams 21 are connected to the two belt frame crossbeams 22, forming the belt frame. The outer side of the middle section of the belt frame longitudinal beams 21 along its length is connected to the drive module 18, while the outer sides of both ends along its length are connected to the self-balancing measurement system 4 and the motor gear integration device 16. The lower side of the belt frame longitudinal beams 21 is connected to the lower side plate 34 of the belt support and is reinforced and fixed to the motor gear integration device 16 via belt frame reinforcing rods 23. The upper side is connected to the long frame plate 31 of the belt support. The belt frame longitudinal beams 21 are used to bear and support the overall structure, capable of transmitting the vertical load of the belt and distributing the load evenly. Their regular shape provides installation positions for other accessories.

[0085] The belt frame crossbeam 22 is made of alloy steel and its two ends are connected to the belt frame longitudinal beam 21 along its length. The two ends of the belt frame crossbeam 22 are connected to the motor gear integration device 16. The belt frame crossbeam 22 connects the two belt frame longitudinal beams 21 to prevent them from becoming unstable and deformed, and to distribute the load evenly so that the belt frame system 2 forms a stable structure.

[0086] The belt frame reinforcing rod 23 is made of alloy steel and has an overall cylindrical structure. Its upper end is connected to the belt frame longitudinal beam 21, and its lower end is connected to the motor gear integration device 16. The belt frame reinforcing rod 23 supports the belt frame system by forming a triangular stable structure with related components, thereby improving the stability of the overall structure.

[0087] Furthermore, the belt support system 3 includes a belt support long frame plate 31, a belt support outer side plate 32, a belt support inner side plate 33, a belt support lower side plate 34, a belt upper idler roller 35, and a belt lower idler roller 36.

[0088] The belt support long frame plate 31 is made of alloy steel, has a cuboid shape, and is welded to the belt frame longitudinal beam 21. It is also welded to the belt support outer side plate 32 and belt support inner side plate 33. It mainly provides support for the upper belt support outer side plate 32 and belt support inner side plate 33.

[0089] The outer side plate 32 of the belt support is made of alloy steel and has a cuboid shape. It is welded to the long frame plate 31 of the belt support at the bottom. The inner side of the outer side plate 32 of the belt support can be used to install the belt upper roller 35, providing support and fixation for the belt upper roller 35.

[0090] The inner side plate 33 of the belt support is made of alloy steel and has a cuboid shape. It is welded to the long frame plate 31 of the belt support at the bottom. The belt upper roller 35 can be installed on the upper side plate 33 of the belt support, which mainly supports and fixes the belt upper roller 35.

[0091] The lower side plate 34 of the belt support is made of alloy steel and has a cuboid shape. It is welded to the longitudinal beam 21 of the belt frame at the top and connected to the lower belt roller 36 between the two lower side plates. It is mainly used to fix the lower belt roller 36 and prevent the belt from shifting.

[0092] The belt idler roller 35 is made of alloy steel, has a strong load-bearing capacity, and is U-shaped. It is composed of three idlers and mainly serves to support the belt and prevent the belt from running off-center. The belt idler roller 35 is hinged to the outer side plate 32 of the belt support on both sides and the inner side plate 33 of the belt support on the lower side. This can increase the material loading capacity, and at the same time, it can roll around its own axis and reduce the friction of the belt, ensuring safe and efficient operation.

[0093] The belt lower idler roller 36 is made of alloy steel and is a single cylindrical flat roller. It is connected to the belt support lower side plate 34 by a pin-type hinge on both sides. It can roll around its own axis to reduce the friction of the belt and support the return belt.

[0094] Furthermore, the self-balancing measurement system 4 includes a self-balancing measurement communication module 401, a support base 402, a self-balancing hemispherical gimbal 403, a laser detection module 404, a dustproof housing 405, a rotating dust removal arm 406, a rotating shaft 407, an atomizing nozzle 408, a cleaning rotating motor 409, a booster pump 410, a water storage tank 411, a water suction pipe 412, an air suction pipe 413, a delivery pipe 414, and a wireless electromagnetic valve 415, such as... Figure 10 As shown.

[0095] The self-balancing measurement and communication module 401 has a stainless steel casing to prevent corrosion. It is rectangular in shape, with its side connected to the belt frame longitudinal beam 21 and its top connected to the support base 402. Its main function is to wirelessly receive the leveling signal from the laser detection module 404. After receiving the signal, it completes data calculation and leveling strategy planning, and simultaneously sends precise execution commands to the drive module 18. Upon triggering the command, the wire 17 is energized, and the drive module 18, in conjunction with the motor gear integrated device 16, precisely controls the extension and retraction of the vertical lifting column 13 through gear rotation. After the vertical lifting column 13 has completed its adjustment, the current in the wire 17 is interrupted, and the gears, after leveling, drive the laser detection module 404 again for retesting to ensure balance. Additionally, the external belt frame longitudinal beam 21 provides installation space for the self-balancing measurement and communication module 401 and prevents obstruction.

[0096] The outer shell of the support base 402 is made of stainless steel to prevent corrosion. It is rectangular in shape, with the lower part connected to the self-balancing measurement and communication module 401, and the upper part embedded with a self-balancing hemispherical gimbal 403. This protects the self-balancing hemispherical gimbal 403 and provides space for its rotation and automatic balancing. The self-balancing hemispherical gimbal 403 is made of stainless steel and is hemispherical. The hemispherical shape of the self-balancing hemispherical gimbal 403 fits the support base 402.

[0097] The self-balancing hemispherical gimbal 403 uses wear-resistant bushings on its lower rotating parts, and a laser detection module 404 is installed on the upper part of the hemisphere. The self-balancing hemispherical gimbal 403 can automatically level itself above the support base 402. The self-balancing hemispherical gimbal 403 contains a cleaning rotation motor 409, a booster pump 410, a water tank 411, a water suction pipe 412, a suction pipe 413, a delivery pipe 414, and a wireless electromagnetic valve 415. The self-balancing hemispherical gimbal 403 also contains a gyroscope and an accelerometer, which can sense angular velocity and the direction of gravity.

[0098] The laser detection module 404 is made of stainless steel, is cubic in shape, and is mounted on a self-balancing hemispherical gimbal 403, with a rotating shaft 407 passing through its center. Several laser emitters are located on the sides of the laser detection module 404. These laser detection modules 404 can communicate and identify each other, calculating the high or low position of a particular laser module and generating adjustment commands. The laser detection module 404 transmits these commands from the self-balancing measurement and communication module 401 to the drive module 18 for execution. The laser emitters are mainly used for laser emission focusing; if a deviation occurs, the laser detection module 404 will detect it and make corresponding adjustments. In addition, the laser detection module 404 can control the start of the cleaning rotation motor 409, the booster pump 410, and its wireless electromagnetic valve 415. When the laser emitter detects that there is a lot of dust on the surface of the dustproof housing 405, which blocks the transmission of the laser signal, the laser detection module 404 starts an emergency cleaning operation. The laser detection module 404 will control the cleaning rotation motor 409, the booster pump 410, and the wireless electromagnetic valve 415 to clean and dry the dustproof housing 405. The laser detection module 404 is equipped with a timing device inside, and the timed cleaning interval can be set through the laser detection module 404, such as thirty minutes, sixty minutes, ninety minutes, etc.

[0099] The dustproof housing 405 is made of polycarbonate, which is transparent, has good impact resistance, and can be repeatedly cleaned by high-pressure water. It is shaped like a hemispherical cover with a seamless curved surface, making it easy to clean dust accumulation. The dustproof housing 405 encloses and protects the laser detection module 404 inside, and the outside is a rotating dust removal arm 406, which is connected to the central rotating shaft 407. The main function of the dustproof housing 405 is to prevent dust from blocking laser emission and to isolate external moisture and other effects, thus extending the service life of the laser detection module 404.

[0100] The rotating dust-collecting arm is made of 406 stainless steel, semi-circular in shape, hollow inside, and connected to a rotating shaft 407 at its center. The rotating shaft 407 drives the rotating dust-collecting arm 406 to rotate. During the rotation of the rotating dust-collecting arm 406, the booster pump 410 works simultaneously to complete water spraying cleaning and air drying. Several atomizing nozzles 408 are evenly arranged on the inner side of the rotating dust-collecting arm 406, precisely pointing towards the dustproof outer shell 405 to achieve comprehensive coverage. The interior of the rotating dust-collecting arm 406 serves as a channel for high-pressure water and drying air.

[0101] The rotating shaft 407 is made of stainless steel and has a cylindrical structure with a hollow internal structure, serving as a channel for high-pressure water and drying air. The rotating shaft 407 passes through the center of the laser detection module 404 and the center of the dustproof shell 405, and is connected to the bottom of the cleaning rotating motor 409 inside the self-balancing hemispherical gimbal 403. The bottom of the rotating shaft 407 is connected to the delivery pipe 414, and the upper side of the rotating shaft 407 is connected to the rotating dust removal swing arm 406. The interior of the rotating shaft 407 is completely connected to the interior of the rotating dust removal swing arm 406, which not only enables the overall rotation through the cleaning rotating motor 409, but also provides a channel for the high-pressure water and drying air transmitted by the booster pump 410.

[0102] The atomizing nozzle 408 is made of stainless steel and has a cubic structure. It is hollow inside and has spray holes on one side facing the surface of the dustproof housing 405. Several atomizing nozzles 408 are evenly arranged inside the rotating dust removal arm 406, precisely facing the dustproof housing 405, and can spray water and blow drying air. The cleaning rotating motor 409 is an ordinary electric motor with good waterproof sealing. It has a cylindrical structure and is installed in the self-balancing hemispherical gimbal 403, with the rotating shaft 407 passing through its center.

[0103] The cleaning rotary motor 409 provides power to the rotating shaft 407 and controls the rotation of the rotating shaft 407, thereby driving the rotating dust removal arm 406 to rotate; the cleaning rotary motor 409 is controlled and started by the laser detection module 404; the booster pump 410 is a waterproof electric booster pump 410, which has an overall cylindrical structure and is installed on the side of the water storage tank 411. It is externally connected to two wireless electromagnetic valves 415, which are respectively connected to the water suction pipe 412 and the air suction pipe 413.

[0104] The booster pump 410 is connected to the rotating shaft 407 via a delivery pipe 414; the booster pump 410 is started by the laser detection module 404.

[0105] The water storage tank 411 is made of stainless steel, has a cuboid shape, and is installed in the self-balancing hemispherical gimbal 403, adjacent to the booster pump 410. Its main function is to store water and provide a water source for the booster pump 410.

[0106] The water suction pipe 412 is a rubber steel wire hose with a circular shape. One end is connected to the wireless electromagnetic valve 415 of the water suction pipe 412, and the other end is placed at the bottom of the water storage tank 411.

[0107] The suction pipe 413 is a rubber steel wire hose with a circular shape. One end is connected to the wireless electromagnetic valve 415 of the suction pipe 413, and the other end passes through the self-balancing hemispherical gimbal 403 for easy air intake.

[0108] The delivery pipe 414 is a rubber steel wire hose with a circular shape. One end is connected to the booster pump 410, and the other end is connected to the bottom of the rotating shaft 407. It serves as a channel for water and drying air.

[0109] The wireless electromagnetic valve 415 is made of stainless steel, has a cuboid shape, and is connected to the booster pump 410. There are two wireless electromagnetic valves 415; specifically, one wireless electromagnetic valve 415 is connected to the water suction pipe 412, and the other wireless electromagnetic valve 415 is connected to the air suction pipe 413. The wireless electromagnetic valve 415 is controlled by the laser detection module 404 to realize the opening and closing functions.

[0110] The method for using an automatic leveling mine conveyor belt support: This invention uses a laser detection module 404 as the core sensing component, equipped with a self-balancing hemispherical gimbal 403, a self-balancing measurement and communication module 401, and a drive module 18, to jointly achieve automatic leveling of the conveyor belt support under roadway floor deformation, such as... Figure 14 As shown. The specific steps are as follows: (i) In the initial state, when the tunnel floor is free from deformation and its flatness meets the benchmark requirements, all laser detection modules 404 maintain a horizontal calibration state, and each execution module is in a low-power standby mode, such as... Figure 5 As shown; (ii) When the tunnel floor bulges, the support will shift. The self-balancing hemispherical gimbal 403 senses the flatness deviation in real time through the built-in sensing unit. Once the deviation signal is detected, the adaptive leveling program is immediately started. Through the leveling of the self-balancing hemispherical gimbal 403 itself, the laser detection module 404 mounted on it is ensured to be the same as the initial state, eliminating interference factors in the subsequent measurement process. (III) After the self-balancing hemispherical gimbal 403 is leveled, several laser detection modules 404 can communicate and identify each other, detect and calculate their own high or low position through the laser emitter, and form control commands; then, the laser detection module 404 transmits the formed control commands wirelessly to the self-balancing measurement and communication module 401 to provide data support for the subsequent leveling strategy formulation. (iv) The self-balancing measurement and communication module 401 is used to perform data calculation after receiving the control command and to send a leveling command to the drive module 18 simultaneously. After receiving the leveling command, the drive module 18 is used to supply power to the high torque motor 161 and the lifting column locker 14 in the motor gear integration device 16 through the wire 17. The lifting column locker 14 controls the lifting column locking tongue 15 to separate from the vertical lifting column 13. If the bracket at the corresponding position is too high, the high torque motor 161 drives the pinion 162 to rotate clockwise. If the bracket at the corresponding position is too low, the high torque motor 161 drives the pinion 162 to rotate counterclockwise, so as to accurately control the lifting stroke of the vertical lifting column 13, thereby achieving accurate compensation for the deformation deviation of the base plate. (v) After the vertical lifting column 13 is adjusted to the position, the high torque motor 161 stops rotating, and the lifting column locking device 14 controls the lifting column locking tongue 15 to lock tightly with the vertical lifting column 13. After locking, if the laser detection module 404 is on the same horizontal plane, the operation ends and each module returns to standby mode. If the laser detection module 404 is not on the same horizontal plane, repeat steps (iii-v) until the detection result meets the requirements.

[0111] The cleaning and drying of the automatic leveling mine belt conveyor support requires the coordinated operation of a rotating dust removal arm 406, a rotating shaft 407, an atomizing nozzle 408, a cleaning motor 409, a booster pump 410, and a water storage tank 411. It features both timed cleaning and emergency cleaning modes. The specific steps are as follows: Regular cleaning, such as Figure 15 As shown (the cleaning program starts automatically every 30 minutes according to the preset cycle). (1) The laser detection module 404 starts the timed cleaning operation according to the preset time interval. The wireless electromagnetic valve 415 connected to the water suction pipe 412 is opened, the wireless electromagnetic valve 415 connected to the air suction pipe 413 is closed, and the booster pump 410 is started. The water delivery path is: water storage tank 411 → water suction pipe 412 → booster pump 410 → delivery pipe 414 → rotating shaft 407 → rotating dust removal arm 406 → atomizing nozzle 408. The atomizing nozzle 408 sprays water onto the surface of the dustproof shell 405 and cleans it. (2) After step (1) is completed, the wireless electromagnetic valve 415 connected to the water suction pipe 412 is closed, the wireless electromagnetic valve 415 connected to the air suction pipe 413 is opened, and the booster pump 410 continues to run; the delivery path of the drying air is: air suction pipe 413 → booster pump 410 → delivery pipe 414 → rotating shaft 407 → rotating dust removal arm 406 → atomizing nozzle 408. The atomizing nozzle 408 sprays the drying air onto the surface of the dustproof shell 405 and dries it. (3) During the execution of steps (1) and (2), the cleaning motor 409 drives the rotating shaft 407 to rotate, and the rotating shaft 407 drives the rotating dust removal arm 406 to rotate circumferentially, so as to achieve complete coverage of the dustproof shell 405. Figure 12 As shown; (4) The laser detection module 404 stops the timed cleaning operation and starts the countdown for the next timed cleaning operation.

[0112] Emergency cleaning, such as Figure 16 As shown (the emergency cleaning function will be triggered when excessive dust or other factors obstruct laser detection). (A) The laser detection module 404 starts the emergency cleaning operation.
