Description

Technical Field

[0001] This utility model relates to the field of coal conveyor belt inspection technology, specifically a single-rail liftable coal conveyor belt inspection system. Background Technology

[0002] Coal conveyor belts transport coal using belt conveyors. During operation, manual inspections are required to ensure the normal operation of the conveyor belts. However, the coal conveying environment is dusty and labor-intensive. Currently, more and more power generation companies are beginning to apply intelligent technologies and information equipment, using intelligent inspection cameras to replace traditional manual inspections. This achieves all-weather, full-coverage, and all-round inspections, and uploads the data to the back-end management system, promptly issuing alarm information to achieve rapid response and decision-making, effectively reducing the operational risks and personal safety risks of coal conveyor belts.

[0003] Currently, existing coal conveyor belt inspection cameras suffer from significant dust accumulation in the coal conveying environment. Although the lenses are protected by tempered glass covers, the coal dust buildup directly leads to unclear images, affecting the intelligent recognition system and consequently the judgment. Therefore, we propose a single-track liftable coal conveyor belt inspection system. Utility Model Content

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Example 1: Refer to Figures 1-5 This utility model provides a single-track liftable coal conveyor belt inspection system, including an inspection box 1 and a traveling track 2. The inspection box 1 is equipped with a traveling mechanism, and an electric telescopic rod 12 is fixedly installed inside the inspection box 1. An intelligent inspection camera body is fixedly installed at the bottom of the electric telescopic rod 12. The electric telescopic rod 12 can drive the intelligent inspection camera body to move up and down. The inspection box 1 can be used to store and protect the intelligent inspection camera body.

[0023] The inspection box 1 has a cleaning structure inside, a cleaning component inside, and an opening 18 at the bottom.

[0024] The cleaning structure includes an annular cylinder 21. An external gear ring 20 is rotatably mounted inside the annular cylinder 21 via bearings. An avoidance groove 19 is provided on the inner wall of the annular cylinder 21. An electric telescopic column 24 is fixedly mounted on one side of the inner cavity of the external gear ring 20. A rubber scraper 13 is fixedly connected to one end of the electric telescopic column 24. A rotating rod 27 is rotatably mounted inside the annular cylinder 21 via bearings. A drive gear 28 is fixedly connected to the surface of the rotating rod 27, and the drive gear 28 meshes with the outer wall of the external gear ring 20. When the electric telescopic rod 12 controls the intelligent inspection camera body to reset, the electric telescopic column 24 is manually activated to make the rubber scraper 13 fit against the side of the lens of the intelligent inspection camera body. The drive motor 26 is started to drive the rotating rod 27 to rotate, which in turn causes the drive gear 28 to drive the external gear ring 20 to rotate. This causes the rubber scraper 13 to rotate around the outside of the intelligent inspection camera body once. The rubber scraper 13 is used to clean the coal ash on the glass dome outside the intelligent inspection camera body 29, thereby ensuring that the image captured by the intelligent inspection camera body is clear and improving the inspection effect.

[0025] The cleaning assembly includes a water tank 14 and an annular pipe 16. The annular pipe 16 is located outside the opening 18 and is fixedly installed inside the inspection box 1. The inner wall of the opening 18 is provided with a spray groove 17. The inner cavity of the water tank 14 is provided with a water pump 15, and the water pump 15 is connected to the annular pipe 16 through a water supply pipe.

[0026] The water tank 14 is installed at the bottom of the inner cavity of the inspection box 1. The water tank 14 is equipped with a water inlet. When the electric telescopic rod 12 carries the intelligent inspection camera body up through the inner cavity of the opening 18, the water pump 15 is started to inject the cleaning fluid in the inner cavity of the water tank 14 into the inner cavity of the annular pipe 16. The cleaning fluid is sprayed out through the spray groove 17 opened on the inner wall of the annular pipe 16, and then the cleaning fluid is sprayed in an annular shape onto the intelligent inspection camera body, so that the intelligent inspection camera body is covered with cleaning fluid.

[0027] The side of the annular cylinder 21 is connected to the inner wall of the inspection box 1. A drive motor 26 is installed on the upper surface of the annular cylinder 21, and the output shaft of the drive motor 26 is fixedly connected to the rotating rod 27.

[0028] The inspection box 1 is equipped with a power supply battery 22, which is used to power the intelligent inspection camera body, electric telescopic column 24, water pump 15, drive motor 26, and drive motor 6. The equipment can be manually controlled or remote control components can be installed. Remote control is a conventional technology in this field. A glass door 23 is hinged on one side of the inspection box 1.

[0029] The walking mechanism includes a walking wheel 4 and a rotating shaft 7. The rotating shaft 7 is rotatably mounted inside the inspection box 1 via bearings. A drive motor 6 is mounted on one side of the inspection box 1. The output shaft of the drive motor 6 is fixedly connected to the rotating shaft 7. Inside the inspection box 1, a transmission column 9 and a wheel axle 3 are rotatably mounted via bearings. A bevel gear 11 is fixedly mounted on the wheel axle 3. One end of the wheel axle 3 extends to the outside of the inspection box 1 and is fixedly connected to the walking wheel 4. The walking wheel 4 cooperates with the walking track 2. A bevel gear 10 is fixedly connected to one end of the transmission column 9. The bevel gear 10 meshes with the bevel gear 11. A bevel gear 5 is fixedly connected to the other end of the transmission column 9. A bevel gear 8 is fixedly mounted on the surface of the rotating shaft 7, and the bevel gear 8 meshes with the bevel gear 5.

[0030] Cleaning plates 25 are fixedly connected to both sides of the inspection box 1, and the lower surface of the cleaning plate 25 is provided with rubber, which is in contact with the walking track 2.

[0031] In summary, this monorail liftable coal conveyor belt inspection system operates by first fixing the travel track 2 to the top plate above the coal conveyor belt using screws or welding. The drive motor 6 drives the rotating shaft 7 to rotate, which in turn drives the second bevel gear 8. The second bevel gear 8, in conjunction with the first bevel gear 5, drives the transmission column 9 to rotate, which in turn drives the traveling wheel 4 via the third bevel gear 10 and the fourth bevel gear 11, allowing it to move along the travel track 2. During inspection, the electric telescopic rod 12 is activated, causing the intelligent inspection camera to move downwards and extend outside the inspection box 1. The camera then captures images of the coal conveyor belt transport, identifies and analyzes the images to determine if any abnormalities have occurred, and transmits the images to a computer backend for viewing by staff. This process enables inspection (this technology is existing and will not be elaborated further).

[0032] When the work is finished or the camera body 29 is contaminated with a large amount of coal dust that affects the shooting, the electric telescopic rod 12 is activated to raise the intelligent inspection camera body 29 through the inner cavity of the opening 18. The water pump 15 is then activated to inject the cleaning fluid from the inner cavity of the water tank 14 into the inner cavity of the annular pipe 16. The cleaning fluid is then sprayed out through the spray groove 17 opened on the inner wall of the annular pipe 16, and then sprayed in a ring onto the intelligent inspection camera body 29. After the electric telescopic rod 12 controls the intelligent inspection camera body 29 to reset, the electric telescopic column 24 is manually activated to extend and retract to its limit distance, so that the rubber scraper 13 is in contact with the side of the lens of the intelligent inspection camera body 29. The drive motor 26 is activated to drive the rotating rod 27 to rotate, which in turn causes the drive gear 28 to drive the outer gear ring 20 to rotate, which in turn causes the rubber scraper 13 to rotate around the outside of the intelligent inspection camera body 29 once. The coal dust on the outside of the intelligent inspection camera body 29 is then cleaned away using the rubber scraper 13.
