Description

TECHNICAL FIELD

[0001] The utility model relates to a belt detection technical field especially relates to a coal conveying power plant belt feeder's belt tear detection device. BACKGROUND

[0002] In the daily operation of the coal conveying power plant, the belt feeder is the key equipment for coal conveying, and its stability and safety in operation are crucial. During the long-term high-intensity work process of the belt feeder, due to the impact of coal, wear and tear, and the aging of the belt itself, etc., the belt is prone to tearing. Once the belt is torn, not only will it cause the interruption of coal conveying, affecting the normal power generation of the power plant, but also may cause a series of safety accidents, causing serious economic losses.

[0003] At present, the belt tear detection technology widely used in coal conveying power plants is mainly based on sensor monitoring and image recognition principles. For example, by installing a pressure sensor under the belt, the pressure change caused by the falling of materials when the belt is torn is used to judge the belt state; or a camera is used to take pictures of the belt surface, and an image processing algorithm is used to identify whether the belt is torn. In terms of mechanical structure, the detection equipment is usually fixedly installed at a specific position of the belt feeder to ensure that the running condition of the belt can be continuously monitored.

[0004] The angle adjustment of the traditional detection device relies on manual operation, and the staff needs to use tools such as wrenches to finely adjust the mechanical structure. However, in the complex and harsh environment of the coal conveying power plant, the space around the belt feeder is narrow, and the dust is everywhere, making manual operation extremely inconvenient. Moreover, frequent manual adjustment not only consumes a lot of manpower and time, but also poses a great safety risk when the belt feeder is running. Therefore, a belt tear detection device for a coal conveying power plant is proposed to solve the above problems. UTILITY MODEL CONTENTS

[0005] In order to make up for the above shortcomings, the utility model provides a belt tear detection device for a coal conveying power plant, aiming to improve the way of adjusting the illumination angle of the detector in the prior art, which relies on manual operation and uses tools such as wrenches to finely adjust the mechanical structure, and the problem of laborious adjustment.

[0006] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0007] A belt tear detection device for a coal conveying power plant, comprising a fixed frame, the fixed frame side wall is provided with a connecting plate, the fixed frame inside is provided with an adjusting assembly, the connecting plate side wall is fixedly connected with a detector, and the detector side wall is provided with a dustproof assembly;

[0008] The adjustment assembly includes a rotating shaft rotatably connected inside the fixed frame. A worm gear is fixedly connected to the side wall of the rotating shaft.

[0023] This utility model has the following beneficial effects:

[0024] 1. In this utility model, the starting motor drives the worm gear to rotate, and through meshing with the worm wheel, the rotating shaft rotates, which in turn drives the connecting rod to rotate in the curved groove, pushing the connecting plate to adjust the detector angle. At the same time, the slider on the side wall of the connecting rod slides in the groove, enhancing the stability of the connecting rod during rotation. This solves the problem that the traditional method of adjusting the detector illumination angle mostly relies on manual operation, using tools such as wrenches to fine-tune the mechanical structure, which is laborious. The above technical solution improves the automation level of detector illumination angle adjustment.

[0025] 2. In this utility model, pressing the button causes it to move down into the sleeve, squeezing the second spring. At the same time, the button drives the locking block to be squeezed by the sleeve and slide into the horizontal groove, compressing the first spring and releasing the lock on the fixing block. The dustproof frame can then be removed for cleaning. This solves the problem that traditional dustproof frames are fastened with bolts and require tools for disassembly, which is quite cumbersome. The above technical solution improves the convenience of cleaning the dustproof frame. Attached Figure Description

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Reference Figure 1 and Figure 2 This utility model provides an embodiment of a belt tear detection device for a coal-fired power plant belt conveyor, comprising a fixed frame 1, a connecting plate 2 provided on the side wall of the fixed frame 1, an adjustment component provided inside the fixed frame 1, a detector 3 fixedly connected to the side wall of the connecting plate 2, and a dustproof component provided on the side wall of the detector 3; the adjustment component includes a rotating shaft 4, which is rotatably connected inside the fixed frame 1, a worm wheel 5 fixedly connected to the side wall of the rotating shaft 4, a worm 6 rotatably connected inside the fixed frame 1, the worm wheel 5 meshing with the worm 6, and the worm wheel 5 rotating due to the interaction between its helical teeth and the teeth of the worm wheel 5; a motor 7 fixedly connected to the side wall of the fixed frame 1, the output end of the motor 7 connected to the worm 6; a connecting rod 8 fixedly connected to the side wall of the rotating shaft 4; a curved groove 19 opened inside the fixed frame 1, the connecting rod 8 slidably connected inside the curved groove 19; a slider 9 fixedly connected to the side wall of the connecting rod 8; a sliding groove 10 opened inside the fixed frame 1, the slider 9 slidably connected inside the sliding groove 10;

[0034] When the illumination angle of detector 3 needs to be adjusted, motor 7 is started. Motor 7 acts as a power source, causing worm 6 to rotate. Worm 6 and worm wheel 5 are meshed. When worm 6 rotates, the interaction between its helical teeth and the teeth of worm wheel 5 causes worm wheel 5 to rotate. Worm wheel 5 is fixedly connected to rotating shaft 4, so the rotation of worm wheel 5 drives rotating shaft 4 to rotate. The rotation of rotating shaft 4 causes connecting rod 8 to rotate inside curved groove 19. Curved groove 19 limits the rotation trajectory of connecting rod 8, thereby driving connecting plate 2 to move. Connecting plate 2 is connected to detector 3, thereby adjusting the illumination angle of detector 3. At the same time, when connecting rod 8 rotates, slider 9 on the side wall slides inside sliding groove 10. Sliding groove 10 guides and limits slider 9, ensuring that connecting rod 8 will not deviate during rotation, making connecting rod 8 more stable, and thus ensuring the smoothness of detector 3 angle adjustment process.

[0035] Reference Figure 3 and Figure 4The dustproof assembly includes a dustproof frame 11, which is slidably connected to the side wall of the detector 3. A fixing block 12 is fixedly connected to the side wall of the dustproof frame 11. A sleeve 13 is fixedly connected to the side wall of the connecting plate 2. A button 14 is slidably connected inside the sleeve 13. The fixing block 12 is slidably connected to the side walls of the sleeve 13 and the button 14. A horizontal groove 15 is opened inside the button 14. A locking block 16 is provided inside the button 14. The locking block 16 is slidably connected inside the horizontal groove 15. A first spring 17 is provided inside the button 14. A second spring 18 is provided inside the sleeve 13. The first spring 17 and the second spring 18 are used for rebound reset. One end of the first spring 17 is fixedly connected to the side wall of the locking block 16, and the other end of the first spring 17 is fixedly connected to the inside of the horizontal groove 15. One end of the second spring 18 is fixedly connected to the side wall of the button 14, and the other end of the second spring 18 is fixedly connected to the inside of the sleeve 13.

[0036] When cleaning the dustproof frame 11 is required, press button 14. Button 14 is an operating component, allowing personnel to apply external force. Pressing it causes it to move downwards, entering the sleeve 13 and compressing the second spring 18. The second spring 18 acts as a buffer and reset mechanism. When button 14 is pressed, it is compressed and stores elastic potential energy. Simultaneously, the movement of button 14 causes the locking block 16 to be compressed by the sleeve 13. The locking block 16 is connected to button 14 and, under the compression, enters the transverse groove 15 and compresses the first spring 17. The first spring 17 also has a buffer and reset function, storing elastic potential energy when the locking block 16 compresses it. When the locking block 16 enters the transverse groove 15, it releases the fixing block 12. The fixing block 12 is used to fix the dustproof frame 11 in the corresponding position. After the locking block 16 no longer fixes the fixing block 12, the dustproof frame 11 can be removed for cleaning, making the cleaning and maintenance of the dustproof frame 11 convenient and quick.

[0037] Working principle: When it is necessary to adjust the illumination angle of detector 3, start motor 7 to make worm 6 start to rotate. Worm 6 and worm wheel 5 are meshed, which in turn makes worm wheel 5 rotate and drives rotating shaft 4 to rotate. The rotation of rotating shaft 4 causes connecting rod 8 to rotate inside curved groove 19, which drives connecting plate 2 to move and adjust the illumination angle of detector 3. At the same time, when connecting rod 8 rotates, slider 9 on the side wall slides inside sliding groove 10, making connecting rod 8 more stable.

[0038] When the dust cover frame 11 needs to be cleaned, press button 14 to move it downwards, enter the sleeve 13 and squeeze the second spring 18. At the same time, the movement of button 14 causes the locking block 16 to be squeezed by the sleeve 13, enter the horizontal groove 15 and squeeze the first spring 17. When the locking block 16 enters the horizontal groove 15, it releases the fixing block 12 and the dust cover frame 11 can be removed for cleaning.

[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
