Description

Technical Field

[0001] This utility model belongs to the field of robotics technology, and in particular relates to a self-cleaning device for an intelligent inspection robot. Background Technology

[0002] In the field of intelligent inspection, inspection robots have been widely used in various complex working environments. The cameras they carry, as core sensing components, are key to realizing equipment status monitoring and environmental information collection. However, in actual operation, dust, oil, water vapor condensate and other pollutants are easily attached to the surface of the camera. Especially in dusty, humid or oily working environments, pollutants are prone to remain for a long time or even clump together, which leads to a decrease in the clarity of the camera image. In severe cases, it can cause problems such as distorted inspection data, missed inspections and false inspections, which directly affect the accuracy and reliability of the robot's inspection work.

[0003] Chinese patent application CN222328175U discloses a self-cleaning coal conveying inspection robot, relating to the field of coal conveying inspection robot technology. This utility model includes a robot body with two cameras mounted on its lower surface. Symmetrically distributed support plates are fixedly mounted on the bottom of the robot body, and symmetrically distributed rotating rods pass through the opposite sides of the two support plates. Symmetrically distributed fixed boxes are fixedly mounted below the robot body, with both rotating rods passing through the fixed boxes. Two gears are fixedly sleeved on the outer sides of each of the two rotating rods, each gear located within one of the fixed boxes. A rack is meshed with the bottom of each gear, and a connecting plate is fixedly mounted on the bottom of the rack in a T-shape. This application incorporates a movable air jet pipe, enabling the air jet pipe to clean dust from the camera surface, preventing dust from obscuring the cameras and degrading the inspection effect.

[0004] While this patent addresses the issue of reduced inspection effectiveness caused by dust accumulation by incorporating a movable and adjustable jet mechanism to blow away loose dust from the camera surface, this technical solution relies on the non-contact cleaning principle of airflow. Its cleaning ability is limited for oil stains, dust adhering to the surface in humid environments, or slight condensation. Although the airflow direction can be optimized by adjusting the jet angle, the shear force generated by the airflow is insufficient to effectively peel off and remove adhesive contaminants, resulting in incomplete cleaning.

[0005] To address this issue, we provide a self-cleaning device for intelligent inspection robots. Utility Model Content

[0006] The purpose of this invention is to provide a self-cleaning device for an intelligent inspection robot, which solves the problem of poor cleaning effect of existing self-cleaning devices for inspection robots by combining a camera and a cleaning component.

[0007] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution.

[0008] This utility model relates to a self-cleaning device for an intelligent inspection robot, comprising a robot body. A camera is rotatably connected to the bottom of the robot body. A cleaning component is provided on the surface of the camera. The cleaning component includes a fixed plate, the bottom of which is detachably connected to the camera. A motor is fixedly connected to the top of the fixed plate, and a main sprocket is fixedly connected to the output end of the motor. A chain is meshed on the surface of the main sprocket, and a secondary sprocket is meshed on the bottom inner side of the chain. One side of the secondary sprocket is rotatably connected to the fixed plate. A sliding rod is fixedly connected to the surface of the chain, and a movable plate is slidably connected to the surface of the sliding rod. The rear side of the movable plate slides against the fixed plate. The mobile plate is detachably connected to a cleaning plate on its front side. A brush is fixedly connected to the inner side of the cleaning plate, and a scraper is provided at the bottom of the brush. One side of the scraper is fixedly connected to the cleaning plate. The fixed plate is connected to the camera by bolts. All cleaning components are integrated on the surface of the fixed plate, which can reduce spatial interference to the robot's inspection operation and avoid interference with other components. Both sides of the scraper are inclined, which can guide the contaminants that fall off during the cleaning process to slide down in a direction and avoid contaminants accumulating on the camera surface. The surface of the mobile plate has a groove, and the inner cavity of the groove is slidably connected to a slide rod, so that the slide rod moves with the chain and drives the mobile plate to move.

[0009] The present invention is further configured such that connecting components are provided on both sides of the cleaning plate, each connecting component including a pressure rod, the surface of which is slidably connected to the cleaning plate, a spring fixedly connected to the other side of the pressure rod, the other side of which is fixedly connected to a movable plate, an insertion rod fixedly connected to one end of the pressure rod, the surface of which is slidably connected to the movable plate, and a locking plate fixedly connected to the other end of the insertion rod. A locking groove is provided on the inner side of the movable plate, and both sides of the locking plate are slidably connected to the locking groove. The other end of the pressure rod extends to the surface of the cleaning plate, so that it can not only be used as an operating component for the insertion rod, but also restrict the movement of the spring to prevent displacement or twisting during its extension and contraction.

[0010] The present invention is further configured such that pulleys are rotatably connected to the inner cavity of the robot body, and the number of pulleys is multiple, so that the robot body can walk along the I-beam.

[0011] The present invention is further configured such that a mounting plate is fixedly connected to the top of the fixing plate, and one side of the mounting plate is fixedly connected to the motor. The mounting plate can provide stable support for the motor and ensure its stability during operation.

[0012] The present invention is further configured such that there are multiple brushes, which are evenly distributed on the inner side of the cleaning plate. The multiple evenly distributed brushes increase the contact area with the camera surface, and the force is more even during cleaning, avoiding local pressure concentration that could cause lens scratches.

[0013] The present invention is further configured such that a pressure plate is provided on the surface of the cleaning plate, and one side of the pressure plate is fixedly connected to the pressure rod. The pressure plate can increase the contact area between the hand and the pressure rod, so that the staff can press the pressure rod more easily.

[0014] The present invention is further configured such that a connecting plate is fixedly connected to the surface of the pressure rod, and one side of the connecting plate is fixedly connected to the spring. The connecting plate can not only be used as a connecting part between the pressure rod and the spring, but also can limit the range of motion of the pressure rod.

[0015] The present invention is further configured such that sliding grooves are provided on both sides of the fixed plate, and a slider is slidably connected to the inner cavity of the sliding groove. The other side of the slider is fixedly connected to the moving plate. The sliding groove and the slider can provide precise positioning and guidance for the moving plate.

[0016] The present invention has the following beneficial effects.

[0017] 1. The cleaning component of this utility model uses a transmission mechanism consisting of a motor-driven chain and sprocket to drive the slide bar and moving plate in continuous reciprocating linear motion. This allows the cleaning plate and its brushes and scrapers to stably and reliably scrape the camera lens surface repeatedly, effectively overcoming the shortcomings of insufficient cleaning power of simple air blowing. It has a significant removal effect on adhesive dust and light oil stains, thus ensuring clear vision of the camera in harsh industrial environments. The integrated design of the brushes and scrapers on the cleaning plate achieves synergy between sweeping and scraping functions. The brushes can penetrate into crevices and sweep away loose particles, while the scrapers can apply concentrated pressure to scrape away hardened stains. The two work together in reciprocating motion, improving the thoroughness and efficiency of cleaning.

[0018] 2. The connecting assembly of this utility model uses the continuous elastic force applied by the spring to the pressure rod to drive the insertion rod and the locking plate to be stably embedded in the slot of the moving plate. This achieves tool-free quick locking and separation between the cleaning plate and the driving component. In addition, this structure ensures that the working position of the cleaning plate is firm and reliable, while effectively simplifying the disassembly steps. It is convenient for maintenance personnel to quickly replace or clean the easily damaged brushes and scrapers, thereby improving the maintenance convenience and work efficiency of the entire device.

[0026] The technical solutions of the present utility model will be described below with reference to the accompanying drawings. The described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0027] Please see Figure 1-5 This utility model relates to a self-cleaning device for an intelligent inspection robot, comprising a robot body 1, a camera 2 rotatably connected to the bottom of the robot body 1, a cleaning component 3 on the surface of the camera 2, and a fixing plate 301. The bottom of the fixing plate 301 is detachably connected to the camera 2, and a motor 302 is fixedly connected to the top of the fixing plate 301. A main sprocket 303 is fixedly connected to the output end of the motor 302, and a chain 304 is meshed on the surface of the main sprocket 303. The bottom of the inner side of the chain 304 is... A secondary sprocket 305 is engaged, and one side of the secondary sprocket 305 is rotatably connected to the fixed plate 301. A slide bar 306 is fixedly connected to the surface of the chain 304, and a movable plate 307 is slidably connected to the surface of the slide bar 306. The rear side of the movable plate 307 is slidably connected to the fixed plate 301. A cleaning plate 308 is detachably connected to the front side of the movable plate 307. A brush 309 is fixedly connected to the inner side of the cleaning plate 308. A scraper 310 is provided at the bottom of the brush 309, and one side of the scraper 310 is fixedly connected to the cleaning plate 308.

[0028] Specifically: the fixed plate 301 is connected to the camera 2 by bolts, and the cleaning components are all integrated on the surface of the fixed plate 301, which can reduce spatial interference to the inspection operation of the robot body 1 and avoid interference with other components. The scraper 310 is inclined on both sides, which can guide the pollutants that fall off during the cleaning process to slide down in a direction and prevent the pollutants from accumulating on the surface of the camera 2. The surface of the moving plate 307 has a groove, and the inner cavity of the groove is slidably connected to the slide rod 306, so that when the slide rod 306 moves with the chain 304, it drives the moving plate 307 to move.

[0029] Please see Figure 1-5 Both sides of the cleaning plate 308 are provided with connecting components 4. The connecting components 4 include a pressure rod 401, the surface of which is slidably connected to the cleaning plate 308. A spring 402 is fixedly connected to the other side of the pressure rod 401, and the other side of the spring 402 is fixedly connected to the moving plate 307. One end of the pressure rod 401 is fixedly connected to an insertion rod 403, the surface of which is slidably connected to the moving plate 307. The other end of the insertion rod 403 is fixedly connected to a locking plate 404. A locking groove 405 is provided on the inner side of the moving plate 307, and both sides of the locking plate 404 are slidably connected to the locking groove 405. The inner cavity of the robot body 1 rotates. The cleaning plate 308 is equipped with multiple pulleys 5. A mounting plate 6 is fixedly connected to the top of the fixed plate 301. One side of the mounting plate 6 is fixedly connected to the motor 302. Multiple brushes 309 are evenly distributed inside the cleaning plate 308. A pressure plate 7 is provided on the surface of the cleaning plate 308. One side of the pressure plate 7 is fixedly connected to the pressure rod 401. A connecting plate 8 is fixedly connected to the surface of the pressure rod 401. One side of the connecting plate 8 is fixedly connected to the spring 402. Slide grooves 9 are provided on both sides of the fixed plate 301. A slider 10 is slidably connected to the inner cavity of the slide groove 9. The other side of the slider 10 is fixedly connected to the moving plate 307.

[0030] Specifically: the other end of the pressure rod 401 extends to the surface of the cleaning plate 308, so that it can not only be used as an operating part of the insertion rod 403, but also restrict the movement of the spring 402 to prevent displacement or twisting during its extension and contraction. The pulley 5 allows the robot body 1 to walk along the I-beam. The mounting plate 6 provides stable support for the motor 302 to ensure its stability during operation. Multiple evenly distributed brushes 309 increase the contact area with the surface of the camera 2, so that the force is more even during cleaning and avoids local pressure concentration that could cause lens scratches. The pressure plate 7 increases the contact area between the hand and the pressure rod 401, so that the operator can press the pressure rod 401 more easily. The connecting plate 8 can not only be used as a connecting part between the pressure rod 401 and the spring 402, but also restrict the range of motion of the pressure rod 401. The slide groove 9 and the slider 10 provide precise positioning and guidance for the moving plate 307.

[0031] The working principle of this utility model is as follows: During use, the camera 2 detects dust on the lens surface using a built-in sensor, thereby activating the motor 302. The motor 302 drives the chain 304 via the main sprocket 303. The chain 304 drives the secondary sprocket 305 to rotate, causing the slide rod 306 to rotate along with the chain 304. The slide rod 306 drives the moving plate 307 to move up and down through a slot. The moving plate 307 drives the cleaning plate 308 to move. The cleaning plate 308 drives the brush 309 and scraper 3... 10. The surface of camera 2 is cleaned repeatedly. When the cleaning plate 308 needs to be removed, the pressure plate 7 is pressed. The pressure plate 7 drives the pressure rod 401 to move and compress the spring 402. The insertion rod 403 moves with the pressure rod 401. The insertion rod 403 drives the card plate 404 to disengage from the inner cavity of the card slot 405. Then, the insertion rod 403 is rotated by the pressure rod 401. The insertion rod 403 drives the card plate 404 to rotate. After reaching the designated position, the insertion rod 403 can be pulled out from the moving plate 307, thus completing the disassembly.
