Description

Technical Field

[0001] This utility model belongs to the field of conveyor belt operation status monitoring technology, and in particular relates to an openable and closable dynamic dustproof cover for conveyor belts. Background Technology

[0002] Background: In industrial and mining production scenarios, belt conveyor systems widely use cameras for operational status monitoring. To improve monitoring efficiency, a single camera typically needs to cover multiple belts or related equipment (such as bucket elevators), and multi-position observation is achieved by rotating the camera.

[0003] The existing technology has the following drawbacks: (1) Generally, fixed protective covers can provide basic dust protection. In order to facilitate observation inside the protective cover, a viewing window is provided. The viewing window is fixed in position and needs to be opened manually for observation. If an independent camera is set up, the viewing window will be open for a long time, which will cause dust to escape.

[0004] (2) If no viewing window is provided and the camera is placed inside the dust cover, the camera is easily damaged by material impact and dust intrusion, resulting in a sharp reduction in the lifespan of the equipment; (3) The current protection scheme lacks a dynamic opening and closing structure, making it difficult to balance the contradiction between equipment protection and monitoring flexibility.

[0005] Therefore, there is an urgent need for a dust cover that can be used to observe the belt operation status and material conditions without adding new cameras, and can be opened and closed directionally with position feedback, so as to meet the monitoring needs while ensuring the safety of the cameras. Utility Model Content

[0006] To address the problems existing in the prior art, this utility model provides an openable and closable dynamic dustproof cover for conveyor belts.

[0007] This utility model is implemented as follows: an openable and closable dynamic dustproof cover for conveyor belts, installed above the conveyor belt frame, characterized in that: it includes several fixed covers arranged along the conveyor belt direction, and a movable cover unit located between adjacent fixed covers; the movable cover unit is set corresponding to the on-site camera acquisition point.

[0008] More preferably, the movable cover unit includes a movable cover body, the lower end of which is equipped with at least four wheels, of which at least one set of wheels are electrically driven wheels.

[0009] More preferably, the belt conveyor frame is provided with a traveling guide rail, and a first limit seat and a second limit seat are respectively provided at both ends of the traveling guide rail; a first limit switch is provided on the first limit seat to detect the closed state of the moving cover; a second limit switch is provided on the second limit seat to detect the open state of the moving cover.

[0010] More preferably, the outer edges of the fixed cover on both sides of the movable cover are provided with outwardly extending dustproof baffles.

[0011] More preferably, the electrically driven wheels have a power-off self-locking function.

[0012] The advantages and technical effects of this utility model are as follows: This utility model addresses the contradiction between dynamic monitoring and dust prevention in traditional fixed dust covers (i.e., the dust cover needs to be opened during camera monitoring, but traditional fixed covers cannot be partially opened or closed, leading to dust prevention failure or obstruction of monitoring during dust prevention). Through a combined structure of "fixed cover body + movable cover unit," it achieves dynamic linkage between dust prevention and monitoring, resulting in significant overall technical effects. A fixed cover is set along the belt conveyor direction to form a basic dustproof frame, covering non-monitoring areas. A mobile cover unit is set corresponding to the camera acquisition points. Driven by electrically driven wheels, the mobile cover moves precisely along the guide rail. When the camera needs to monitor the corresponding belt, the PLC controls the mobile cover to automatically open (the second limit switch signals completion upon reaching the second limit seat), exposing the monitoring area. After the camera moves away, the mobile cover automatically closes (the first limit switch signals completion upon reaching the first limit seat), restoring its dustproof function. The four-wheel structure (including electrically driven wheels) enhances movement stability and adapts to the complex environment of the belt conveyor frame. The guide rail ensures precise movement and avoids deviation. Limit switches achieve closed-loop control through physical limits and signal feedback to prevent over-movement and ensure equipment safety.

[0013] In addition, the dustproof baffles on both sides of the movable cover extend outward to enhance lateral sealing, reduce dust leakage from the gap between the cover and the belt or the side, and optimize the dustproof effect; the power-off self-locking function of the electric drive wheels locks the position of the movable cover when the system is powered off or malfunctions, preventing accidental sliding from affecting the dustproof or collision equipment and improving safety.

[0014] In summary, this utility model, through structural innovation and control linkage, not only ensures the unobstructed nature of on-site video monitoring but also maintains high-efficiency dustproof performance, balancing monitoring functions and environmental protection requirements, and significantly improving the automation level, operational reliability, and on-site environmental management effectiveness of the equipment.

[0017] To make the objectives, technical solutions, and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this utility model.

[0018] Please see Figures 1 to 3 An openable and closable dynamic dustproof cover for a conveyor belt is installed above the conveyor belt frame. It includes several fixed covers 101 arranged along the conveyor belt direction, and a movable cover unit 200 located between adjacent fixed covers 101. The movable cover unit 200 is set to correspond to the on-site camera acquisition point.

[0019] More preferably, the movable cover unit 200 includes a movable cover body 201, the lower end of which is equipped with at least four wheels 202, of which at least one set of wheels is electrically driven.

[0020] More preferably, the belt conveyor frame is provided with a traveling guide rail 102, and the two ends of the traveling guide rail 102 are respectively provided with a first limit seat 103 and a second limit seat 104; the first limit seat 103 is provided with a first limit switch 105 for detecting the closed state of the moving cover 201; the second limit seat 104 is provided with a second limit switch 106 for detecting the open state of the moving cover 201.

[0021] More preferably, the outer edges of the fixed covers 101 on both sides of the movable cover 201 are provided with outwardly extending dustproof baffles 107.

[0022] Further preferably, the electric drive wheels have a power-off self-locking function.

[0023] The technical effects of the above-mentioned technical features and combinations are as follows: The combination of a fixed dust cover and a mobile dust cover unit: The fixed dust cover 101 forms a basic dustproof frame along the belt conveyor direction, while the mobile dust cover unit 200 dynamically adapts to the camera acquisition points, resolving the contradiction between dynamic monitoring and dust prevention that traditional fixed dust covers cannot simultaneously address. The mobile dust cover unit 200 can be opened and closed selectively, ensuring unobstructed camera monitoring while also closing to prevent dust from spreading when not monitoring, effectively suppressing dust diffusion and improving on-site environmental performance.

[0024] Mobile enclosure walking structure: The lower end of the mobile enclosure 201 is equipped with at least four walking wheels 202 (including electrically driven wheels), which enable automated movement via electric drive, reducing manual operation; the four-wheel structure enhances movement stability and adapts to the complex environment of belt conveyor frames. The electrically driven wheels can precisely control the movement speed and position, providing a hardware foundation for dynamic dust prevention and monitoring linkage.

[0025] Travel guide rail and limit switches: The travel guide rail 102 provides a precise movement path for the movable cover 201 to avoid deviation; the first limit switch 105 and the second limit switch 106 detect the closed and open states respectively, and realize closed-loop control through physical limit and signal feedback to prevent the movable cover 201 from moving excessively, ensure the safe operation of the equipment, and provide status basis for PLC control.

[0026] Dust baffle design: Dust baffles 107 extending outward are provided on the outer edges of the fixed cover 101 on both sides of the movable cover 201 to enhance the lateral sealing between the dust cover and the belt, reduce dust from escaping from the gap between the cover and the belt or the side, further optimize the dust prevention effect, and adapt to high dust conditions on site.

[0027] Electric drive wheels with power-off self-locking: The electric drive wheels have a power-off self-locking function. When the system loses power or malfunctions, the moving cover 201 automatically locks its current position to prevent accidental sliding due to gravity or external force, avoids the cover shifting and affecting the dustproof effect or collision with equipment, and significantly improves the safety and reliability of the system.

[0028] Working principle: When the main control room issues the command "align with belt number one", the camera rotates to the corresponding position on belt number one. Simultaneously, the PLC receives the command and sends a control signal to the electrically driven wheels of the corresponding moving cover unit 200, driving the moving cover 201 to move along the guide rail 102 in the "open" direction. During the movement, when the moving cover 201 touches the second limit seat 104, the second limit switch 106 detects the "open state" and sends a feedback signal to the PLC, completing the opening action and ensuring unobstructed camera monitoring.

[0029] When the camera needs to be turned to another belt or area, the PLC sends another command to the electric drive wheels, driving the movable cover 201 to move along the guide rail 102 in the "closed" direction. When the movable cover 201 touches the first limit seat 103, the first limit switch 105 detects the "closed state" and sends a feedback signal, realizing automatic closure and restoring the dustproof function. The entire process ensures accurate positioning through the status detection of the limit switches, and the automated control of the electric drive wheels achieves dynamic linkage between the opening and closing of the dustproof cover and camera monitoring, balancing dustproof requirements and monitoring functions.

[0030] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
