Description

Technical Field

[0001] This utility model relates to the field of sluice gate engineering technology, specifically to an automatic cleaning device for sliding contact lines used in sluice gate engineering. Background Technology

[0002] In sluice gate engineering, the sliding contact line serves as the core mobile power supply carrier for critical power equipment such as gate hoists and winches. Its conductivity directly determines the stability and reliability of operations such as sluice gate opening and closing and water level control. Since sluice gate projects are mostly located in outdoor environments, the sliding contact line is constantly exposed to damp, dusty, and insect-infested conditions, easily accumulating cobwebs, dust, and other minor debris. This debris increases the contact resistance between the sliding contact line and the equipment brushes, causing problems such as localized overheating and unstable power supply. In severe cases, it may even lead to equipment shutdown. Therefore, regular cleaning of the sliding contact line is necessary. The core requirement is to remove surface debris through mechanical cleaning to ensure the smooth flow of the power supply circuit.

[0003] For example, Chinese patent CN213484154U discloses an H-type single-pole combined automatic cleaning device for sliding contact lines, including a cleaning brush and an installation assembly. The cleaning brush includes a strip brush, a fixing plate, and two insulating plates. The two insulating plates are clamped on both sides of the fixing plate, and one end of the two insulating plates protrudes from the fixing plate to form a clamping groove. The strip brush is inserted into the clamping groove and fixed to the fixing plate. The installation assembly includes a current collector shoe box and two clamps. The cleaning brush is inserted into the current collector shoe box, with the strip brush protruding. The two clamps are clamped on both sides of the current collector shoe box. One end of the clamp is connected to the current collector shoe box, and the other end has an installation part. This utility model uses a waste current collector and current collector bracket to install the cleaning brush, realizing synchronous and automatic cleaning of dirt, foreign objects, and oxide layers in the H-type single-pole combined sliding contact line groove when the crane trolley is moving. This ensures good contact between the current collector and the sliding contact line when the crane is running, resulting in a highly efficient cleaning effect on the sliding contact line groove and reducing the amount of manual cleaning work.

[0004] The above-mentioned solution has the advantages mentioned above, but its disadvantages are that it lacks independence, relies on the movement of the crane trolley for synchronous sweeping, cannot start operation independently, has no independent power supply system, and is not equipped with its own power supply and wind and solar energy supplementation structure. It is completely dependent on the operation of the crane, has weak sweeping adaptability, the sweeping brush is a fixed structure, and has no self-adjusting function of multi-section connecting rods, making it difficult to fully fit the sliding contact line. In addition, it lacks remote control design, resulting in low operation convenience. Utility Model Content

[0005] To address the shortcomings of existing technologies, the technical solution adopted by this utility model is as follows: an automatic cleaning device for sliding contact lines in sluice gate engineering, comprising: a frame, wherein slide rails are symmetrically provided on the outer wall of the frame, a movable plate is slidably connected to the inner wall of the slide rails of the frame, and a fixed plate is fixedly connected to the outer wall of the end of the frame away from the movable plate; a spring connecting rod is fixedly connected to the inner wall of the movable plate and the fixed plate by a nut, and a drive wheel is symmetrically rotatably connected to the inner wall of the fixed plate; the drive wheel is stepped and has teeth on its outer ring, and a power source is meshed with the outer wall of the teeth of the drive wheel. The machine includes a gear, a movable plate with symmetrically rotatably connected inner walls to traveling wheels, a square steel tube fixedly connected to the outer wall of the movable plate, an infrared photoelectric rangefinder symmetrically fixedly connected to the inner wall of the square steel tube, multiple connecting rods rotatably connected to the outer wall of the square steel tube, an insulating brush rotatably connected to one end of the connecting rods, a control device on the bottom outer wall of the frame, a support rod fixedly connected to the side wall of the fixed plate, a magnetic connector fixedly connected to one end of the support rod, a magnetic base snapped into one end of the magnetic connector, and a protective box fixedly connected to the outer wall of the magnetic base. The outer wall of the insulated brush is slidably connected to a sliding contact line. In use, the device initially rests at the end point of the sliding contact line's working area. At this time, the side wall of the fixing plate, secured by a magnetic connector on a support rod, precisely engages with the magnetic base. The magnetic base is further electrically connected to the external solar panel and fan, forming a complete charging circuit. The battery in the control device continuously receives power through this circuit, providing sufficient power for subsequent cleaning operations. Simultaneously, the power display collects real-time battery voltage and power data and converts the monitoring signal into electrical signals. The signal is transmitted to the main controller, and staff can intuitively monitor the power status through a remote terminal to avoid affecting operations due to insufficient power. From the perspective of structural balance and protection, the control box is fixed to the outer wall of the bottom of the frame. Its own weight and the square steel pipe, multi-section connecting rod and other components on the upper part of the device form a gravitational balance, effectively preventing the device from tilting along the I-beam when in standby or operation. The protection box is made of waterproof and dustproof material, and the interior forms a sealed space, completely wrapping the magnetic base and the wires and terminals at the connection point, isolating the water vapor, dust and corrosive gases at the sluice gate site, and ensuring the long-term stable operation of the charging circuit components.

[0006] Preferably, the control device includes a control box. The inner wall of the control box is fixedly connected to a battery, a power display, a remote control switch, a main controller, a relay, and an inverter. The outer wall of the control box is fixedly installed to the bottom outer wall of the frame, achieving a balanced state with the overall structure of the device through its own weight. The remote control switch supports remote control via a remote control or mobile phone. When a remote control command is triggered, the battery and magnetic charging circuit are automatically disconnected, and the device responds to the walking command. When a worker initiates a cleaning command via the remote control or mobile APP, the device enters the remote start process. The remote control switch has a built-in LoRa low-power wide-area network module, adaptable to the complex outdoor signal environment of sluice gate projects, and adopts the Modbus-RTU remote control protocol, which has strong anti-interference capabilities. The stable data transmission effectively avoids electromagnetic interference from on-site motors, frequency converters, and other equipment. It first receives wireless commands from the remote control or mobile app. Then, the remote switch converts the wireless commands into standard TTL level signals, which are transmitted to the main controller's command receiving port via a shielded signal line. Upon receiving the start signal, the main controller immediately performs a logical judgment: on one hand, it sends a start command to the inverter, which converts the DC power output from the battery into AC power to provide power to the main controller, external drive mechanisms, and relays; on the other hand, it sends a switching command to the relay, causing the normally closed contacts of the relay to open, disconnecting the battery from the magnetic charging circuit, while the normally open contacts close, connecting the drive mechanism's power circuit, thus completing the standby charging state switch.

[0007] Preferably, the infrared photoelectric rangefinder is electrically connected to the main controller in the control box via a connecting cable, forming a limit control loop. The battery, power display, remote control switch, main controller, relay, and inverter are electrically connected to each other. After the loop switching is completed, the main controller sends an operation command to the external drive motor. The drive motor drives the power gear to rotate. Since the teeth on the outer ring of the drive wheel mesh with the power gear, the torque of the power gear is transmitted to the drive wheel through the tooth meshing, causing the drive wheel to roll along the outer wall of the I-beam next to the sliding contact line. At the same time, the traveling wheels symmetrically installed on the inner wall of the movable plate are symmetrically distributed with the drive wheel and roll synchronously along the outer wall of the I-beam with the drive wheel. The two work together to form a four-point support structure to ensure that the device moves smoothly along the I-beam track. The moving speed can be adjusted by the main controller. To meet the cleaning needs of sliding contact lines of different lengths, the spring connecting rod between the movable plate and the fixed plate plays a crucial role during the cleaning process. The spring connecting rod has a built-in compression spring that always maintains elastic tension. When there are differences in the specifications of the I-beams next to the sliding contact line, adjusting the nut near the movable plate or the spring connecting rod can reduce or increase the distance between the movable plate and the fixed plate, ensuring that the drive wheels and traveling wheels are always in close contact with the outer wall of the I-beam to prevent slippage. At the same time, the multi-section connecting rod, which is rotatably connected to the outer wall of the square steel tube through bearings, adopts a foldable structure. The insulating brush at its end adaptively adjusts the contact angle with the surface of the sliding contact line through the universal rotation characteristics of the multi-section connecting rod. As the device moves along the I-beam, the brush bristles remove the oxide layer, dust, and debris inside the sliding contact line.

[0008] Preferably, the multi-section connecting rod adopts a foldable structure, and the bristle length is adapted to the cleaning requirements of the sliding contact line. To prevent the device from colliding with the end of the I-beam or debris on site during movement, the device is equipped with a limit protection system based on an infrared photoelectric rangefinder. The infrared photoelectric rangefinders, symmetrically fixed to the inner wall of the square steel tube, face forward and backward in the direction of travel, respectively. They monitor the path environment in real time by emitting modulated infrared light and receiving reflected light. When an obstacle appears in front of the device, such as a limit block at the end of the I-beam or a fallen tool, and the infrared photoelectric rangefinder detects a distance signal from the reflected light that is less than a preset threshold, it immediately converts the distance signal into a digital signal. The obstacle signal is transmitted to the limit signal port of the main controller via the bus. After receiving the obstacle signal, the main controller triggers the emergency protection logic. First, it sends a stop command to the drive mechanism to cut off the power to the drive motor, and the drive wheels and walking wheels stop rotating. Second, it controls the relay to reset and disconnects the drive power circuit to prevent accidental restart of the device. Finally, it sends an obstacle alarm signal to the remote terminal through the remote control switch to prompt the staff to handle the situation. At this time, the device remains stationary in its current position and waits for the staff to send subsequent instructions through the remote terminal. After the instructions are confirmed, the main controller releases the protection state, reconnects the power circuit, and the device continues to perform its work.

[0009] Preferably, the walking wheels and drive wheels are symmetrically distributed, the power gear is connected to the external drive mechanism, and the protective box is made of waterproof and dustproof material, forming a sealed space inside to protect the magnetic base and connection structure. When the cleaning operation is completed, or when the power display detects that the battery is low, the main controller automatically triggers a reset process, or a reset command is sent by the operator via a remote terminal. The main controller sends a reverse rotation command to the drive mechanism, the drive motor drives the power gear to rotate counterclockwise, and the drive wheels and walking wheels roll in opposite directions, causing the device to retraceive along the original path of the I-beam; during the retracing process, infrared photoelectric ranging is used. The device continuously monitors the path to ensure a smooth return along the original track and avoid deviation. When the device returns to the initial standby position, the magnetic connector on the fixed plate side automatically aligns with and engages with the magnetic base under the combined action of gravity and magnetic attraction. Subsequently, the main controller sends a reset command to the relay, which closes the normally closed contact, reconnecting the battery and magnetic charging circuit. The battery begins charging again. At the same time, the main controller sends a reset completion and charging start feedback signal to the remote terminal. The staff can then confirm that the device has returned to a safe standby state. Thus, the device completes the full closed loop of cleaning, resetting, and charging, and awaits the next cleaning command.

[0010] The beneficial effects of this utility model are as follows: 1. This utility model reduces manual operation by setting up a fully mechanized operating structure, a balance wheel, and infrared limit controllers at both ends. The balance wheel ensures that the machine runs smoothly along the I-beam and prevents it from derailing. The infrared limit controllers enable automatic stopping at the cleaning endpoint. This helps to avoid the risks of manual operation and machine operation accidents, improves the safety factor of operation, and improves the defects of prominent safety hazards.

[0011] 2. This utility model, by setting up a lithium battery, combined with wind and solar power supply and an automatic magnetic charging structure at the end point, is designed for cleaning needs of light debris such as cobwebs and dust. It can operate independently without the power supply of the sliding contact line, which helps to reduce power consumption. At the same time, it can be remotely controlled by remote control or mobile APP using the Modbus-RTU protocol, without the need for on-site human intervention, thus improving the inconvenience of operation of existing cleaning methods.

[0016] Please see Figure 1 - Figure 6 This utility model provides a technical solution: an automatic cleaning device for sliding contact lines in sluice gate engineering, comprising: a frame 1, with symmetrically arranged slide rails on the outer wall of the frame 1, a movable plate 3 slidably connected to the inner wall of the slide rails of the frame 1, and a fixed plate 2 fixedly connected to the outer wall of the end of the frame 1 away from the movable plate 3; a spring connecting rod 4 is fixedly connected to the inner wall of the movable plate 3 and the fixed plate 2 by nuts; a drive wheel 5 is symmetrically rotatably connected to the inner wall of the fixed plate 2, the drive wheel 5 is stepped and has teeth on its outer ring, a power gear 11 is meshed with the outer wall of the teeth of the drive wheel 5, and a traveling wheel 6 is symmetrically rotatably connected to the inner wall of the movable plate 3. A square steel pipe 7 is fixedly connected to the outer wall of plate 3. An infrared photoelectric rangefinder 8 is symmetrically fixedly connected to the inner wall of the square steel pipe 7. A multi-section connecting rod 9 is rotatably connected to the outer wall of the square steel pipe 7. An insulating brush 10 is rotatably connected to the outer wall of one end of the multi-section connecting rod 9. A control device 12 is provided on the outer wall of the bottom end of the frame 1. A support rod 13 is fixedly connected to the side wall of the fixed plate 2. A magnetic connector 14 is fixedly connected to the outer wall of one end of the support rod 13. A magnetic base 15 is snapped onto the outer wall of one end of the magnetic connector 14. A protective box 16 is fixedly connected to the outer wall of the magnetic base 15. A sliding contact line 17 is slidably connected to the outer wall of the insulating brush 10.

[0017] The control device 12 includes a control box 120. The inner wall of the control box 120 is fixedly connected to a battery 121, a power display 122, a remote control switch 123, a main controller 124, a relay 125, and an inverter 126. The outer wall of the control box 120 is fixedly installed to the bottom outer wall of the frame 1. The control box 120 is balanced with the overall structure of the device by its own weight. The remote control switch 123 supports remote control by a remote control or mobile phone. When the remote control command is triggered, the battery 121 is automatically disconnected from the magnetic charging circuit, and the device responds to the walking command.

[0018] The infrared photoelectric rangefinder 8 is electrically connected to the main controller 124 in the control box 120 via a connecting cable, forming a limit control circuit. The battery 121, power display 122, remote control switch 123, main controller 124, relay 125 and inverter 126 are electrically connected to each other.

[0019] The multi-section connecting rod 9 has a foldable structure, and the bristle length is adapted to the cleaning needs of the sliding contact line body 17.

[0020] The walking wheels 6 and the drive wheels 5 are symmetrically distributed. The power gear 11 is connected to the external drive mechanism. The protective box 16 is made of waterproof and dustproof material, and its interior forms a sealed space to protect the magnetic base 15 and the connection structure.

[0021] Working principle: In operation, the device initially rests at the end of the working area of ​​the sluice gate sliding contact line 17. At this time, the magnetic connector 14 fixed to the side wall of the stationary plate 2 by the support rod 13 precisely engages with the magnetic base 15. The magnetic base 15 is further electrically connected to the external solar panel and fan, forming a complete charging circuit. The battery 121 in the control device 12 continuously replenishes power through this circuit, providing sufficient power for subsequent cleaning operations. At the same time, the power display 122 collects the voltage and power data of the battery 121 in real time and converts the monitoring signal into an electrical signal for transmission to the main control unit. The controller 124 allows staff to intuitively monitor the power status via a remote terminal, preventing operational disruptions due to insufficient power. From a structural balance and protection perspective, the control box 120 is fixed to the outer wall of the bottom of the frame 1. Its own weight, along with the square steel pipe 7 and multi-section connecting rods 9 on the upper part of the device, forms a gravitational balance, effectively preventing the device from tilting along the I-beam during standby or operation. The protection box 16 is made of waterproof and dustproof material, forming a sealed space inside that completely encloses the magnetic base 15 and the wires and terminals at the connection points, isolating the water gate site from moisture, dust, and corrosive gases, ensuring the long-term stable operation of the charging circuit components.

[0022] When staff initiate a cleaning command via remote control or mobile app, the device enters the remote start process. The remote control switch 123, with its built-in LoRa low-power wide-area network module, is adapted to the complex outdoor signal environment of sluice gate projects. It adopts the Modbus-RTU remote control protocol, which boasts strong anti-interference capabilities and stable data transmission, effectively avoiding electromagnetic interference from on-site motors, frequency converters, and other equipment. First, it receives the wireless command sent by the remote control or mobile app; then, the remote control switch 123 converts the wireless command into a standard TTL level signal, which is transmitted through a shielded signal cable to… The main controller 124 receives a start signal and immediately performs a logical judgment: on the one hand, it sends a start command to the inverter 126, which converts the DC power output from the battery 121 into AC power to provide power to the main controller 124, the external drive mechanism, and the relay 125; on the other hand, it sends a switching command to the relay 125, which opens the normally closed contact of the relay 125, disconnecting the connection between the battery 121 and the magnetic charging circuit, and at the same time closes the normally open contact to connect the power circuit of the drive mechanism, thus completing the standby charging state switching.

[0023] After the circuit switching is completed, the main controller 124 sends an operation command to the external drive motor. The drive motor drives the power gear 11 to rotate. Since the teeth on the outer ring of the drive wheel 5 mesh with the power gear 11, the torque of the power gear 11 is transmitted to the drive wheel 5 through the tooth meshing, causing the drive wheel 5 to roll along the outer wall of the I-beam next to the sliding contact line 17. At the same time, the traveling wheels 6, which are symmetrically installed on the inner wall of the movable plate 3, are symmetrically distributed with the drive wheel 5 and roll synchronously along the outer wall of the I-beam with the drive wheel 5. The two work together to form a four-point support structure to ensure that the device moves smoothly along the I-beam track. The moving speed can be adjusted by the main controller 124 to adapt to the cleaning needs of sliding contact lines 17 of different lengths. During the cleaning process, the spring connection between the movable plate 3 and the fixed plate 2... Rod 4 plays a crucial role. The spring connecting rod 4 has a built-in compression spring, which always maintains an elastic tension. When there are differences in the specifications of the I-beam next to the sliding contact line 17, the nut near the end of the movable plate 3 can be adjusted to compress or the spring connecting rod 4 can be adjusted to shrink or expand the distance between the movable plate 3 and the fixed plate 2, ensuring that the drive wheel 5 and the traveling wheel 6 are always in close contact with the outer wall of the I-beam to avoid slippage. At the same time, the multi-section connecting rod 9, which is rotatably connected to the outer wall of the square steel tube 7 through the bearing, adopts a foldable structure. The insulating brush 10 at its end adaptively adjusts the contact angle with the surface of the sliding contact line 17 through the universal rotation characteristics of the multi-section connecting rod 9. As the device moves along the I-beam, the brush bristles remove the oxide layer, dust and debris inside the sliding contact line 17.

[0024] To prevent the device from colliding with the ends of the I-beams or debris during its movement, the device is equipped with a limit protection system based on infrared photoelectric rangefinders 8. The infrared photoelectric rangefinders 8, symmetrically fixed to the inner wall of the square steel tube 7, face forward and backward along the device's direction of travel, respectively. They monitor the surrounding environment in real time by emitting modulated infrared light and receiving reflected light. When an obstacle appears in front of the device, such as a limit block at the end of the I-beam or a fallen tool, and the infrared photoelectric rangefinder 8 detects a distance signal from the reflected light that is less than a preset threshold, it immediately converts the distance signal into a digital signal and transmits it to the limit signal port of the main controller 124 via a bus. After receiving an obstacle signal, the main controller 124 triggers the emergency protection logic. First, it sends a stop command to the drive mechanism, cutting off the power to the drive motor, and the drive wheel 5 and the walking wheel 6 stop rotating. Second, it controls the relay 125 to reset, disconnecting the drive power circuit to prevent accidental restart of the device. Finally, it sends an obstacle alarm signal to the remote terminal via the remote control switch 123 to prompt the staff to handle the situation. At this time, the device remains stationary in its current position, waiting for the staff to send subsequent instructions via the remote terminal. After the instructions are confirmed, the main controller 124 deactivates the protection state, reconnects the power circuit, and the device continues to perform its work.

[0025] When the cleaning operation is completed, or when the power display 122 detects that the remaining power of the battery 121 is insufficient, the main controller 124 automatically triggers the reset process, or a reset command is sent by the staff via a remote terminal. The main controller 124 sends a reverse rotation command to the drive mechanism, the drive motor drives the power gear 11 to rotate counterclockwise, and the drive wheel 5 and the walking wheel 6 roll in opposite directions, and the device retraces along the original path of the I-beam; during the retracing process, the infrared photoelectric rangefinder 8 continuously monitors the path to ensure that the device returns smoothly along the original track and avoids deviation. When the device returns to the initial standby position, the fixing plate 2... Under the combined action of gravity and magnetic attraction, the magnetic connector 14 on the side automatically aligns with and snaps into the magnetic base 15. Subsequently, the main controller 124 sends a reset command to the relay 125, and the normally closed contact of the relay 125 closes, reconnecting the battery 121 and the magnetic charging circuit. The battery 121 starts charging again. At the same time, the main controller 124 sends a feedback signal to the remote terminal indicating that the reset is complete and charging has started. The staff can confirm that the device has returned to the safe standby state. Thus, the device completes the complete closed loop of cleaning, resetting, and charging, and waits for the next cleaning command.

[0026] Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art and related fields based on the embodiments of this utility model without creative effort should fall within the protection scope of this utility model. Structures, devices, and operating methods not specifically described and explained in this utility model, unless otherwise specified or limited, shall be implemented according to conventional means in the art.
