Description

Technical Field

[0001] This application relates to the field of cleaning technology, and more particularly to a cleaning device for the bottom surface of equipment. Background Technology

[0002] Currently, in the field of cleaning technology, cleaning the bottom surface of equipment such as the bottom of electrolytic aluminum tanks is a core step in ensuring accurate temperature measurement by temperature measuring devices and smooth movement of temperature measuring vehicles. However, existing technologies for cleaning the bottom surface of equipment such as electrolytic aluminum tanks mainly involve manual entry into the tank bottom area or cleaning vehicles entering the equipment's bottom passage for cleaning. Manual cleaning carries significant safety risks due to high temperatures, dust, strong magnetic fields, and potential falls, and is also inefficient. Cleaning vehicles are not only bulky and unable to navigate narrow passages, but large pieces of material can also affect their stable movement. Therefore, these methods cannot meet the industry's demand for high-efficiency cleaning. Summary of the Invention

The fan is mounted on the vehicle body and connected to the dust collection component, which is vertically detachable on the vehicle body. The roller brush is mounted on the dust collection component, and the dust collection box is connected to the bottom of the dust collection component. The fan draws the dust-laden airflow cleaned by the roller brush into the dust collection box through the dust collection component. The slag removal mechanism includes a vertically detachable push plate mounted on the vehicle body. When the push plate descends to a predetermined height, it pushes the blocky material on the bottom surface of the equipment into a collection pit for collecting the blocky material.

[0010] Optionally, the push plate is equipped with an obstacle avoidance sensor. When the obstacle avoidance sensor detects that the distance between the block material and the push plate is less than a predetermined distance threshold, the push plate descends to the predetermined height to push the block material on the bottom of the device into the collection pit for collecting the block material.

[0011] Optionally, the cleaning device further includes a walking mechanism, which includes: multiple lifting outriggers, quick-release components, and multiple anti-magnetic hub motors. The lifting outriggers are detachably connected to the bottom of the vehicle body via the quick-release components.

The drive mechanism is kinetically connected to the roller brush, the fan, and the push plate to drive the roller brush to rotate, the fan to rotate, and the push plate to rise and fall.

[0015] Because the cleaning device is equipped with a height-adjustable roller brush, the dust removal mechanism can remove dust from the bottom surface of the equipment at different heights.

[0023] The following is in conjunction with the appendix Figure 1-6 Explain its structure and working process.

[0024] Please refer to Figure 1 , Figure 2In one embodiment, this application provides a cleaning device for the bottom surface of equipment, including a vehicle body 30, a dust removal mechanism 10, a slag removal mechanism 20, and a drive mechanism 60; the dust removal mechanism 10 includes a fan 105, a dust collection component 103, a roller brush 101, and a dust collection box 106. The fan 105 is mounted on the vehicle body 30 and connected to the dust collection component 103. The dust collection component 103 is vertically and flexibly mounted on the vehicle body 30. The roller brush 101 is mounted on the dust collection component 103. The dust collection box 106 is connected to the dust collection component... The bottom of 103 is connected, and the fan 105 draws the dust-laden airflow cleaned by the roller brush 101 into the dust collection box 106 through the dust collection component 103; the slag removal mechanism 20 includes a push plate 202 that can be raised and lowered on the vehicle body 30. When the push plate 202 is lowered to a predetermined height, it pushes the blocky material on the bottom of the equipment to the collection pit for collecting the blocky material; the drive mechanism 60 is connected to the roller brush 101, the fan 105 and the push plate 202 to drive the roller brush 101 to rotate, the fan 105 to rotate and the push plate 202 to rise and fall.

[0025] The dust collection component 103 and the roller brush 101 of the dust removal mechanism 10 can remove dust from the bottom surface of the equipment at different heights. Combined with the adsorption function of the fan 105, fine dust can be effectively collected, avoiding secondary dust generation and improving the working environment. Secondly, through the design of combining the dust removal mechanism 10 with the slag removal mechanism 20, the roller brush 101 and the fan 105 of the dust removal mechanism 10 can remove dust or oxide layer from the bottom surface of the equipment, and then the push plate 202 in the slag removal mechanism 20 can push lumpy materials (e.g., slag) to the collection pit, so that the cleaning device can complete two cleaning tasks at the same time, thereby improving the cleaning efficiency.

[0026] Considering the unique environment of cleaning the bottom of electrolytic cells, especially the bottom of electrolytic aluminum cells, there are usually high ambient temperatures and rough, hard, agglomerated materials. Therefore, the bristles of the roller brush 101 are preferably made of high-temperature resistant metal materials (such as high-carbon steel or stainless steel wire). Compared to traditional nylon or plastic bristles, the metal roller brush 101 not only has excellent high-temperature resistance, enabling it to work for extended periods under high-temperature conditions without softening, melting, or thermal deformation, but also possesses higher mechanical strength and wear resistance. This effectively copes with the strong friction from the hard oxide layer or slag on the bottom of the cell, significantly extending the service life of the roller brush 101 and ensuring the stability of the cleaning effect.

[0027] Furthermore, such as Figure 1As shown, the fan 105 can be fastened to the top of the vehicle body shell 302 of the vehicle body 30 using fasteners. These fasteners can be any of the following: Phillips head screws, hexagonal nuts, locating pins, bolts, rivets, pins, or clips. The fan 105 can be a negative pressure fan 105, which creates a negative pressure adsorption channel when operating, drawing dust-laden airflow into the dust collection box 106. The dust collection component 103 can be a dust collection hood, fixedly installed below the roller brush 101. It has an arched, upward-facing hood structure with a suction port in the center of its lower part. This hood structure covers the lower half of the roller brush 101, enclosing its working area and preventing dust from being emitted. The roller brush 101 can be cylindrical, and its two sides can be fixed to the sides of the dust collection component 103 using roller brush fixing parts (e.g., roller brush pressure plates 108) to prevent displacement of the roller brush 101 during rotation.

[0028] It is worth noting that the axis of the roller brush 101 can be parallel to the ground or adjusted according to the cleaning angle of the bottom surface of the equipment. When the roller brush 101 rotates and sweeps, the dust raised is confined inside the dust collection component 103, and then sucked into the dust collection box 106 through the suction generated by the connected negative pressure fan 105, thereby achieving a dust-free operation that integrates sweeping and suction.

[0029] In one embodiment, the dust removal mechanism 10 further includes a lifting mechanism 102 and a telescopic pipe 104. The dust collection component 103 is vertically and vertically mounted on the vehicle body 30 via the lifting device to adjust the distance between the dust collection component 103 and the bottom surface of the equipment. The telescopic pipe 104 is installed on the top of the vehicle body 30, with its top connected to the dust collection component 103 and its bottom connected to the dust collection box 106. The fan 105 is fixedly mounted on the top of the vehicle body 30 and connected to the telescopic pipe 104. Through the telescopic pipe 104 and the lifting mechanism 102, the height of the dust removal mechanism 10 can be adjusted, thereby adapting to dust removal operations at different equipment bottom surface heights.

[0030] Further, please see Figure 1The extendable pipe 104 can be a extendable hose. The top of the extendable pipe 104 can be connected to the suction port of the dust collection component 103 via a pipe fastener (e.g., a flange or a clip), and the bottom of the extendable pipe 104 is mounted on the quick-release pressure plate 110 via a pipe fastener. A fan 105 can also be connected to the bottom side of the extendable pipe 104, so that the dust swept by the roller brush 101 is sucked into the dust collection box 106 through the suction port and the extendable pipe 104 by the suction force of the fan 105. The top of the dust collection box 106 has a connecting hole adapted to the extendable pipe 104. The connecting hole can be equipped with a filter bag or filter screen so that after the dust passes through the extendable pipe 104, it is filtered by the filter bag or filter screen and falls into the dust collection box 106 for overall collection and processing.

[0031] It is worth noting that, since the cleaning equipment is continuously exposed to high-temperature heat radiation and hot airflow when operating near the ground (e.g., an electrolytic cell), the body of the telescopic pipe 104 can be made of a high-temperature resistant material to prevent the pipe from softening, melting, or structurally collapsing due to heat. As a preferred embodiment, the telescopic pipe 104 can be made of special polymer materials such as high-temperature resistant silicone, fluororubber, or polytetrafluoroethylene (PTFE). These materials not only maintain stable physicochemical properties under high-temperature environments, preventing thermal deformation or cracking of the pipe, but also possess good flexibility and fatigue resistance, meeting the frequent extension and retraction requirements of the equipment during lifting operations. Furthermore, to enhance the structural stability of the pipe under high-temperature and negative pressure adsorption conditions, a high-temperature resistant spiral steel wire skeleton or glass fiber reinforcement layer can be embedded in the wall of the telescopic pipe 104 to provide radial support, effectively preventing the pipe from collapsing or deforming under the combined effects of high temperature and negative pressure.

[0032] In one implementation, such as Figure 4 As shown, the dust collection box 106 also includes a dust discharge component 1061, which is disposed at the bottom of the dust collection box 106, which is located inside the vehicle body 30. A plug 1061-1 is detachably connected to the bottom of the dust discharge component 1061. The plug 1061-1 is configured to be rotatably opened to discharge dust from the dust collection box 106. Specifically, the top of the dust discharge component 1061 is connected to the bottom of the dust collection box 106, allowing dust in the dust collection box 106 to be discharged through the dust discharge component 1061. The plug 1061-1 is detachably connected to the bottom of the dust discharge component 1061. When the plug 1061-1 is closed, the dust collection box 106 is sealed; when the plug 1061-1 is opened or removed, dust and oxide layers are centrally discharged. The plug 1061-1 can be fixed to the bottom of the dust discharge component 1061 by a snap-fit ​​structure or a threaded connection structure.

[0033] In one implementation, please refer to Figure 3 Multiple lifting mechanisms 102 can be fixedly installed below the cover-like structure of the dust collection component 103. Specifically, the dust removal mechanism 10 may include a dust collection cover connecting plate 107, the middle of which may have a connecting hole (or installation interface). This connecting hole is adapted to the top of the dust collection port or the telescopic pipe 104 of the dust collection component 103, so that the dust collection cover connecting plate 107 can cover or be fixedly connected to the outer surface of the dust collection port or the telescopic pipe 104. The two ends of the dust collection cover connecting plate 107 are fixedly connected to the top of the lifting mechanism 102 by fasteners, while the bottom of the lifting mechanism 102 is fixedly installed on the top of the vehicle body shell 302 of the vehicle body 30.

[0034] Based on the above structure, when the lifting mechanism 102 is driven to adjust the height of the dust collection component 103, the dust collection hood connecting plate 107 rises and falls accordingly, thereby causing the telescopic hose to stretch and deform to adapt to the dust removal needs at different heights.

[0035] In one implementation, for ease of maintenance, such as Figure 5 As shown, the dust removal mechanism 10 also includes a quick-release push-pull plate 112, a quick-release pressure plate 110, and a quick-release mounting plate 113; the quick-release mounting plate 113 is fixed to the top of the vehicle body 30; the quick-release pressure plate 110 is disposed on both sides of the top of the quick-release mounting plate 113, forming a gap between them; the quick-release push-pull plate 112 is slidably disposed within the gap, and the quick-release push-pull plate 112 is connected to the bottom of the telescopic pipe 104. The operator can pull the handle to pull the quick-release push-pull plate 112 out from the gap formed between the quick-release pressure plate 110 and the quick-release mounting plate 113. The quick-release push-pull plate 112 drives the connected telescopic pipe 104 out, which in turn drives the dust collection component 103 and the roller brush 101 to be disassembled, thereby facilitating the cleaning, replacement, or maintenance of the telescopic pipe 104, the dust collection component 103, and the roller brush 101.

[0036] In one embodiment, in addition to dust removal by the dust removal mechanism 10 described above, the present application embodiment can also directly clean lumpy materials by the slag removal mechanism 20. The push plate 202 of the slag removal mechanism 20 is vertically and flexibly positioned above or in the middle of the front end of the vehicle body 30, so that the cleaning device can clean the lumpy materials and facilitate the stable movement of the cleaning device. Wear-resistant shovel teeth can be installed at the front end of the push plate 202 to facilitate the shoveling of hard slag.

[0037] In one implementation, such as Figure 1As shown, the drive mechanism 60 includes a roller brush drive mechanism 601, a fan drive mechanism (not shown), and a push rod 602; the roller brush drive mechanism 601 is driven to the input end of the roller brush 101 to drive the roller brush 101 to rotate; the fan drive mechanism is driven to the input end of the fan 105 to drive the fan 105 to rotate; the push rod 602 can be any one of an electric push rod, a hydraulic cylinder, or a pneumatic rod.

[0038] In one implementation, such as Figure 6 As shown, the roller brush drive mechanism 601 includes a roller brush motor 6011, a coupling 6012, and a sprocket and chain transmission mechanism 6013. The output end of the roller brush motor 6011 is connected to the input end of the coupling 6012, and the output end of the coupling 6012 is connected to the driving sprocket of the sprocket and chain transmission mechanism 6013. The driven sprocket of the sprocket and chain transmission mechanism 6013 is connected to the input end of the roller brush 101. The roller brush motor 6011 is configured to output rotational power, which is transmitted sequentially through the coupling 6012 and the sprocket and chain transmission mechanism 6013, thereby driving the roller brush 101 to rotate. When the fan drive mechanism sends a start signal to the fan 105, the fan 105 is energized and rotates, directly driving the impeller of the fan 105 to rotate at high speed through its output shaft, thereby forming a negative pressure suction airflow inside the dust collection component 103.

[0039] It should be noted that both the roller brush drive mechanism 601 and the fan drive mechanism can be equipped with anti-magnetic housings to shield against external magnetic field interference and protect internal components. The interior of the anti-magnetic housing can accommodate power transmission components such as a motor and a reducer (not shown in the figure) to provide driving force for the entire cleaning device. Both the roller brush drive mechanism 601 and the fan drive mechanism can be implemented using conventional existing technology products in the art. Their specific internal structures and working principles are common knowledge to those skilled in the art and will not be described in detail here.

[0040] Furthermore, such as Figure 1As shown, the vehicle body 30 is also equipped with a linkage mechanism; the push plate 202 is connected to the vehicle body 30 through the linkage mechanism, and the push plate 202 is connected to the output end of the push rod 602, while the input end of the push rod 602 is connected to the vehicle body 30. The linkage mechanism can adopt a parallelogram connection module in conjunction with the adjustment structure of the push rod 602. When the push rod 602 extends or retracts, it drives the linkage mechanism to deform, thereby driving the push plate 202 to move up and down or translate. Furthermore, in order to prevent the roller brush 101 and the push plate 202 from overtravel, a limit component 109 is provided at the other end of the roller brush 101. The limit component 109 may include a limit switch (not shown) and / or a position sensor (not shown). When the roller brush 101 or the push plate 202 and other actuators move to a preset limit position, the trigger element provided on the actuator will press the limit switch or trigger the position sensor, causing the contact state inside the limit switch to switch, or causing the position sensor to generate a corresponding electrical signal. The switching signal or electrical signal will directly cut off the power supply to the control circuit of the roller brush drive mechanism 601 or the push rod 602, or send a limit feedback signal to the controller 502, thereby controlling the corresponding roller brush drive mechanism 601 or push rod 602 to stop driving, thus achieving safety protection.

[0041] Specifically, the parallelogram connection module of the linkage mechanism includes two sets of relatively parallel and equal-length connecting rods. One end of each connecting rod is connected to the vehicle body shell 302 via a hinge shaft (or revolute joint), and the other end is connected to the side of the push plate 202 facing the vehicle body 30 via a hinge shaft (or revolute joint), thus forming a closed-loop parallelogram geometric structure. Based on the kinematic characteristics of the parallelogram connection module, during the lifting and lowering process of the push plate 202, while moving vertically, the push plate 202 also generates a preset horizontal displacement (i.e., left-right / forward-backward translation). Through the cooperation of the parallelogram structure and the linear drive component (i.e., push rod 602), the push plate 202 can perform reciprocating movements back and forth and up and down, realizing the composite trajectory movement of the push plate 202 in space, thereby expanding the working coverage of the cleaning device and improving the cleaning efficiency of dead corner areas on the equipment floor (e.g., the bottom of the tank). When encountering lumpy slag, the operator can control the pusher plate 202 to descend through the controller 502, pushing the lumpy material into the collection pit on one side of the bottom of the equipment. It can also be pushed back and forth multiple times for centralized transport.

[0042] Furthermore, such as Figure 1 As shown, an obstacle avoidance sensor 201 is installed on the push plate 202. When the obstacle avoidance sensor 201 detects that the distance between the block material and the push plate 202 is less than a predetermined distance threshold, the push plate 202 descends to a predetermined height to push the block material on the bottom of the equipment into the collection pit for collecting the block material. This allows for continuous detection of obstacles ahead, and automatic deceleration or stopping when the distance is too close.

[0043] Specifically, when the obstacle avoidance sensor 201 detects that the distance between the blocky material and the pusher plate 202 is less than a predetermined distance threshold, it sends an obstacle avoidance signal to the controller 502. The controller 502 then extends or retracts the pusher rod 602 to control the pusher plate 202 to descend vertically to a predetermined height, or to adjust horizontally to accommodate different blocky material positions, or to switch between working and non-working states. The controller also controls the pusher plate 202 to move forward or upward to push the blocky material into the collection pit. The predetermined height refers to the height at which the pusher plate 202 can push the blocky material. The collection pit can be located at the lowest point of the equipment's bottom surface (e.g., the bottom of the tank), a slag discharge position on one side of the tank, or a collection structure located at the center or edge of the tank bottom.

[0044] In one embodiment, the obstacle avoidance sensor 201 may further include a visual recognition unit (not shown). The visual recognition unit is configured to acquire image information of the material in front and determine whether the detected blocky material meets the collection conditions based on a preset size threshold.

[0045] Specifically, when the visual recognition unit determines that the size of the block material is greater than or equal to a preset size threshold and the block material is within the effective working range of the push plate 202, it sends a trigger signal to the controller 502. The controller 502 then controls the drive mechanism 60 to drive the push plate 202 to perform a descent action, thereby pushing the block material into the collection pit. If the size of the block material is less than the preset size threshold, or the material is not within the effective working range of the push plate 202, the drive mechanism 60 does not trigger the descent action of the push plate 202 (or controls the push plate 202 to maintain its current height), thereby achieving precise cleaning of specific target materials.

[0046] Furthermore, please refer to [link / reference]. Figure 2 The equipment has a vehicle mounting plate 304 at its bottom. The vehicle mounting plate 304 can be a one-piece welded structure and supports all mechanisms or components mounted on it. A vehicle shell 302 is fixed to the vehicle mounting plate 304, forming the main frame of the equipment. To enable movement of the equipment, the cleaning device also includes a walking mechanism 40, which includes multiple lifting outriggers 402, quick-release components 401, and multiple anti-magnetic hub motors 403. The lifting outriggers 402 are detachably connected to the bottom of the vehicle body 30 via the quick-release components 401. The anti-magnetic hub motors 403 are located at the bottom of the lifting outriggers 402 and are used to drive the vehicle body 30 to move. This structure is used to adjust the vehicle body 30 to a horizontal position on uneven ground or to assist in overcoming obstacles.

[0047] Specifically, the quick-release component 401 can be a quick-release pin, enabling rapid replacement of the lifting outrigger 402. The lifting outrigger 402 can be located at the four corners of the vehicle mounting plate 304 or below key stress points. It can be driven by an electric push rod or a hydraulic cylinder, thus achieving independent lifting and lowering. This allows it to adjust the stability of the vehicle body 30 according to the flatness of the ground under the equipment. When there are large unevenness or tracks on the equipment ground (e.g., the bottom of a trough), the lifting outrigger 402 can be operated to lift the vehicle body 30, adjust the height, or overcome obstacles, thereby enabling the entire cleaning device to clean smoothly and efficiently. An anti-magnetic hub motor 403 is fixedly installed at the bottom or end of the lifting outrigger 402. This anti-magnetic hub motor 403 can be a universal wheel or a directional wheel driven by a highly anti-magnetic hub motor. Furthermore, the antimagnetic hub motor 403 contains precision electronic components sensitive to magnetic fields. To prevent external magnetic field interference from causing abnormal control logic or component damage, the driver or controller of the antimagnetic hub motor can be magnetically protected. For example, the driver or controller can be fully enclosed with a magnetically conductive material to construct an effective magnetic shielding layer. In one embodiment, the antimagnetic hub motor 403 can be a caster structure with brakes, thereby enabling flexible movement and stationary positioning of the equipment. As a preferred embodiment, considering the special nature of operating environments such as electrolytic cells, key structural components of the antimagnetic hub motor 403 (such as the motor housing, end caps, or rotor inner ring) can be made of non-magnetic materials, such as non-magnetic composite materials, aluminum alloys, or austenitic stainless steel. This ensures that the antimagnetic hub motor 403 can maintain stable power output even under strong magnetic conditions such as in electrolytic cells, avoiding motor step loss or overheating damage caused by magnetic field interference, and significantly improving the reliability of the entire machine.

[0048] In one implementation, such as Figure 2 As shown, the drive mechanism 60 also includes a battery module 603, which is located inside the vehicle body 30 and provides operating power to the entire cleaning device. In a preferred embodiment, the battery module 603 includes a battery pack and a battery management module (or battery voltage monitoring module). The cleaning device is powered by the battery pack, ensuring mobility. The battery management module is configured to monitor the battery pack's voltage status in real time. When the battery voltage is detected to be below a preset safety threshold (i.e., undervoltage), an alarm is triggered, the power output of the cleaning device is cut off to prevent over-discharge damage to the battery, and the cleaning device is remotely controlled to exit the tank for manual battery replacement or charging.

[0049] In one implementation, such as Figure 2As shown, the cleaning device also includes a control system 50, which includes a remote control receiver 501 and a controller 502. The controller 502 is electrically connected to the remote control receiver 501, the drive mechanism 60, the obstacle avoidance sensor 201, the lifting outrigger 402, and the anti-magnetic hub motor 403. The controller 502 is configured to receive control commands sent by the remote control receiver 501 and control the drive mechanism 60 and the anti-magnetic hub motor 403 to perform corresponding actions according to the detection signal of the obstacle avoidance sensor 201.

[0050] Specifically, the remote control receiver 501 is electrically connected to a remote controller (not shown). When the remote controller sends a control command to the remote control receiver 501, the remote control receiver 501 sends a control command to the controller 502. The controller 502 controls the drive mechanism 60 to rotate. Specifically, the controller 502 outputs a start signal and a speed control signal to the roller brush drive mechanism 601, driving the roller brush 101 to rotate around its axis for cleaning. When the roller brush 101 starts rotating, the controller 502 simultaneously controls the drive fan 105 to start, creating a negative pressure zone inside the dust removal component. Through signal interaction between the controller 502 and the obstacle avoidance sensor 201, the controller 502 automatically controls the lifting and translating of the push plate 202, the height adjustment of the lifting legs 402, and the rotation of the anti-magnetic hub motor 403 according to the obstacle avoidance signal sent by the obstacle avoidance sensor 201.

[0051] In actual operation, the drive mechanism 60 triggers the above actions sequentially or simultaneously according to a preset logic program. It can either activate only the roller brush motor 6011 and the fan 105 for dust removal, or control the push plate 202 to descend to a predetermined height as needed. Specifically, at least one of the following operating modes can be achieved: In mode 1, only the roller brush 101 of the dust removal mechanism 10 is used for cleaning, combined with the negative pressure system of the fan 105, while the push plate 202 can be in the retracted state.

[0052] Mode 2: Only the slag removal mechanism 20 is controlled to perform slag removal, and the roller brush 101 can be configured to be in a non-working state. Specifically, the dust collection component 103 can be raised to a preset avoidance height to prevent the roller brush 101 from contacting the bottom surface of the equipment.

[0053] Mode 3: Dust removal and slag removal can be linked, that is, the push plate 202 is controlled to remove lumpy materials first, and then the roller brush 101 and fan 105 of the dust removal mechanism 10 are controlled to remove dust. Alternatively, the dust removal mode and the slag removal mode can be alternated.

[0054] Mode 4: Only the vehicle body 30 moves, while the dust removal mechanism 10 and the slag removal mechanism 20 are not in operation.

[0055] It is worth noting that when the pusher plate 202 encounters lumpy material that needs to be cleaned, it pushes the lumpy material to the slag collection pit. If no lumpy material that needs to be cleaned is detected, the pusher plate 202 can be in a non-working state. The roller brush 101 sweeps the dust on the bottom surface of the equipment to the dust collection component 103, and the negative pressure airflow generated by the fan 105 instantly sucks the raised dust into the dust collection box, thereby realizing an integrated automated cleaning operation of "sweeping, suction, and pushing".

[0056] Furthermore, the controller 502 is also configured to control the vehicle body 30 to perform differential steering by controlling the rotational speed and direction of each antimagnetic hub motor 403. In one embodiment, the controller 502 can independently control each antimagnetic hub motor 403. Differential steering refers to achieving steering of the vehicle body 30 by independently controlling the rotational speed of the hub motors on both sides of the vehicle body 30, thereby creating a speed difference between the two wheels. Therefore, the controller 502, upon receiving control commands, can control not only the rotational speed of the antimagnetic hub motor 403 but also its direction, facilitating the cleaning of various locations on the bottom surface of the equipment.

[0057] In one embodiment, an emergency stop button (not shown) may also be provided on the vehicle body 30 and the remote controller. In case of an emergency, the emergency stop button can be pressed to immediately cut off the power output.

[0058] In one embodiment, an audible and visual alarm light 70 can also be installed on the top of the vehicle body shell. If an abnormality occurs or an emergency stop is manually pressed, the controller 502 immediately cuts off all power output and triggers the audible and visual alarm 70. The operator can switch the working mode or adjust the vehicle speed at any time via a remote control.

[0059] In summary, the cleaning device of this application utilizes the combined action of a push plate 202 to gather material (i.e., to collect lumpy materials), a roller brush 101 to sweep, and a dust collection component 103 to vacuum under negative pressure. This, along with the adaptive adjustment of the parallelogram lifting mechanism for the vertical and horizontal directions of the push plate 202, the adaptive adjustment of the telescopic pipe 104 and the lifting mechanism 102 for the vertical height of the dust collection component 103, and the independent adjustment of the lifting outriggers 402, achieves the height and movement stability of the vehicle body 30, thereby efficiently completing cleaning tasks in specific areas. Furthermore, the combination of the quick-release push-pull plate 112, the quick-release pressure plate 110, and the quick-release mounting plate 113 makes the telescopic pipe 104, the dust collection component 103, and the roller brush 101 easier to clean, replace, or maintain, thus ensuring the cleaning effect of the dust removal mechanism 10.
