Description

Technical Field

[0001] This utility model relates to the field of inspection device technology, and in particular to a coal bunker inspection device. Background Technology

[0002] Coal bunkers are mostly enclosed structures, a feature that poses a significant challenge to real-time monitoring of critical parameters within the bunker. Traditional inspection methods cannot comprehensively and promptly detect factors such as bunker wall damage, the degree of coal buildup on the walls, humidity levels, coal temperature variations, and the distribution of harmful gases like methane and carbon monoxide. Anomalies are often only discovered after an accident, such as spontaneous combustion of coal at high temperatures, bunker rupture and leakage, or the release of harmful gases. This reactive approach not only poses serious safety risks but can also lead to significant economic losses, including production interruptions and equipment damage. Summary of the Invention

[0003] The purpose of this utility model is to overcome the shortcomings of the existing technology and provide a coal bunker inspection device that integrates multiple functions, reduces safety risks, and provides a strong guarantee for the stable operation of the production process.

Detailed Implementation

[0015] The present invention will be further explained below with reference to the accompanying drawings and embodiments. However, this explanation should not be construed as limiting the scope of protection of the present invention. The purpose of disclosing the present invention is to protect all technical improvements within the scope of the present invention.

[0016] Combined with appendix Figure 1-3 The coal bunker inspection device shown includes an electric slide gate valve 1, a support frame, a winch 3, an inspection robot 4, an AI camera 5, an audible and visual alarm 6, and a 3D level gauge 7; the electric slide gate valve 1, the winch 3, the inspection robot 4, the AI ​​camera 5, the audible and visual alarm 6, and the 3D level gauge 7 are all connected to the host computer system for communication.

[0017] The electric slide gate valve 1 is installed on the top plate of the coal bunker 9; the support frame includes a support frame 1 21 and a support frame 22 arranged opposite to each other. Both support frame 1 21 and support frame 22 are steel structure frames, and support frame 1 21 and support frame 22 are fixedly connected by a connecting rod; support frame 1 21 is installed above the electric slide gate valve 1, and the top of support frame 1 21 is provided with a fixed pulley 211 corresponding to the gate of the electric slide gate valve 1. The winch 3 is installed on the top of support frame 22. The winch 3 is a double-drum structure. Two steel wire ropes are respectively installed through the fixed pulley 211 corresponding to the top of support frame 1 21. The lower ends of the two steel wire ropes are provided with triangular plates 31 to prevent the steel wire ropes from twisting and tangling.

[0018] The AI ​​camera 5 and the audible and visual alarm 6 are mounted on the upper outer side of the support frame via bracket 8. The AI ​​camera 5 is mounted on the side wall of bracket 8 via a universal bracket, and the audible and visual alarm 6 is mounted on the top plate of bracket 8 via a suspension rope. The AI ​​camera 5 collects images of the monitored area in real time and performs human recognition through a built-in algorithm. When it detects that a person has entered the preset warning area, it immediately triggers the audible and visual alarm 6 and transmits the intrusion signal and the on-site image to the host computer system to achieve dual early warning and prevent people from accidentally entering dangerous areas.

[0019] The 3D level gauges 7 are installed on the top plate of the coal bunker 9. The scanning range can cover the entire internal space of the coal bunker 9 without any blind spots. By emitting scanning signals, the surface of the coal material in the coal bunker 9 is scanned in all directions to obtain the three-dimensional coordinate data of the coal material surface. The data processing unit analyzes and calculates the scanning data to obtain the volume and coal level of the coal material in the coal bunker 9. The measurement results are transmitted to the control software of the host computer system to realize the real-time display, storage and historical query of the data, providing accurate basis for the feeding and discharging scheduling of the coal bunker 9.

[0020] The inspection robot 4 includes a control box body 41, a gimbal 42, a gas sensor 43, a temperature and humidity sensor 44, a distance sensor 45, and several supplementary lights 46. A hook 411 is installed on the top of the control box body 41, and the hook 411 is connected to the triangular plate 31 at the lower end of the wire rope of the winch 3. The gimbal 42 is mounted on the lower part of the control box body 41 with screws. The gas sensor 43 and the temperature and humidity sensor 44 are mounted side-by-side with screws on the lower side of the control box body 41, and are positioned at a height higher than the gimbal 42 to avoid obstructing the view when the gimbal 42 rotates. The volume sensor 43 and the temperature and humidity sensor 44 monitor the harmful gases and temperature and humidity in the coal bunker 9, respectively; the distance sensor 45 is installed on the wiring cavity of the gimbal 42 via a mounting plate to detect the position and distance between the inspection robot 4 and the materials in the coal bunker 9 during its descent, and controls the stopping position of the inspection robot 4 via the host computer system to prevent the inspection robot 4 from being bumped; the supplementary light 46 is hinged to each side plate of the control box body 41 via the bracket 412, and the illumination angle of the supplementary light 46 is adjusted by the bracket 412 to supplement the light for the gimbal 42.

[0021] Before the winch 3 starts, the host computer system controls the electric gate valve 1 to open. After the gate is fully opened, the winch 3 starts, and the wire rope is lowered along the fixed pulley. The inspection robot 4 enters the coal bunker 9 through the gate and fully acquires images of the inside of the coal bunker 9 through the gimbal 42. The gas sensor 43 and the temperature and humidity sensor 44 collect the gas and temperature and humidity inside the coal bunker 9. During the descent, the host computer system controls the inspection robot 4 to stop based on the signal detected by the distance sensor 45. After the inspection process is completed, the host computer system controls the winch 3 to lift the inspection robot 4 out of the coal bunker 9, and the cover of the electric gate valve 1 is closed. The 3D level gauge 7 fully acquires and analyzes the volume and coal level inside the coal bunker 9 in real time.
