Description

Technical Field

[0001] This utility model relates to the field of monitoring instrument technology, and more specifically, to a coal mine surface movement and deformation mapping and monitoring instrument. Background Technology

[0002] Coal mine surface movement and deformation refers to the phenomenon and process in which the movement of rock strata caused by mining activities affects the surface, resulting in surface movement, deformation, and damage. In order to protect surface features in coal mining areas from damage by surface subsidence to the greatest extent, it is necessary to conduct surface movement and deformation monitoring.

[0003] Existing methods for monitoring surface movement and deformation involve installing surveying instruments on the surface. However, surface movement and deformation cause vibrations, which in turn cause fluctuations in the monitoring instruments, affecting their stability and leading to errors in the monitoring results. Therefore, we propose a surface movement and deformation monitoring instrument for coal mines. Summary of the Invention

[0004] The main objective of this invention is to provide a coal mine surface movement and deformation mapping and monitoring instrument to overcome the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides a coal mine surface movement deformation mapping and monitoring instrument, including a buffer seat. A support rod is fixedly installed on the upper surface of the buffer seat, and a monitoring instrument is fixedly installed in the middle of the upper surface of the support rod. A buffer box is movably fitted onto the outer surface of the buffer seat. Telescopic rods are movably installed in the middle of the four sides between the bottom surface of the buffer box and the top surface of the buffer seat. A compression spring is fixedly fitted onto the outer surface of the output end of the telescopic rod. Movable shaft seats are fixedly installed at both ends of the telescopic rod. One end of the movable shaft seat is fixedly connected to the bottom surface of the buffer box, and the other end of the movable shaft seat is fixedly connected to the top surface of the buffer seat. Fixed discs are fixedly installed in the middle of the four sides of the outer surface of the buffer seat. A buffer disc is fixedly installed on the side of the fixed disc away from the outer surface of the buffer seat. The buffer discs and fixed discs are arranged in an alternating combination.

[0006] As a further improvement of this utility model, a mounting device is fixedly provided in the middle of the upper surface of the buffer seat, and the mounting device is spirally sleeved and installed on the lower part of the outer surface of the support rod.

[0007] As a further improvement of this utility model, two sets of semi-arc-shaped assembly rings are staggered and fixedly installed on both sides of the upper part of the outer surface of the support rod. Locking rings are fixedly installed at both ends of the assembly rings. Connecting ears are fixedly provided on the outer surface of the ends of the locking rings that connect with the assembly rings. Locking bolts are spirally inserted into the inner surface of the connecting ears.

[0008] As a further improvement of this utility model, a control box is fixedly installed on the middle of the outer surface of one set of assembly rings, and a photovoltaic panel is fixedly installed on the middle of the outer surface of the other set of assembly rings.

[0009] As a further improvement of this utility model, a pressure relief hole is provided through the middle of one side of the outer surface of both the fixed plate and the buffer plate.

[0010] The beneficial effects of this utility model are:

[0011] This invention can buffer the vibration generated during the movement and deformation of the coal mine surface, thereby reducing the fluctuation amplitude of the monitoring instrument caused by vibration. This helps to improve the stability of the monitoring instrument during the monitoring process, thereby reducing monitoring errors. At the same time, it helps to ensure the safe use of the monitoring instrument in a vibration environment and reduce damage. Attached Figure Description

[0022] Please see Figures 1-4 As shown, a coal mine surface movement deformation mapping and monitoring instrument includes a buffer seat 1. A support rod 2 is fixedly installed on the upper surface of the buffer seat 1. An assembly 101 is fixedly installed in the middle of the upper surface of the buffer seat 1. The assembly 101 is spirally sleeved and installed on the lower part of the outer surface of the support rod 2. Two sets of semi-arc-shaped assembly rings 201 are staggered and fixedly installed on both sides of the upper part of the outer surface of the support rod 2. Locking rings 202 are fixedly installed at both ends of the assembly rings 201. Connecting ears are fixedly provided on the outer surface of the ends of the locking rings 202 and the assembly rings 201. Locking bolts 203 are spirally inserted into the inner surface of the connecting ears. A control box 3 is fixedly installed in the middle of the outer surface of one set of assembly rings 201, a photovoltaic panel 4 is fixedly installed in the middle of the outer surface of the other set of assembly rings 201, and a monitoring instrument 5 is fixedly installed in the middle of the upper surface of the support rod 2.

[0023] A buffer box 6 is movably fitted onto the outer surface of the buffer seat 1. Telescopic rods 701 are movably installed on the four sides between the bottom surface of the buffer box 6 and the top surface of the buffer seat 1. A compression spring 702 is fixedly fitted onto the outer surface of the output end of the telescopic rod 701. Movable bearings 7 are fixedly installed at both ends of the telescopic rod 701. One end of the movable bearing 7 is fixedly connected to the bottom surface of the buffer box 6, and the other end of the movable bearing 7 is fixedly connected to the top surface of the buffer seat 1. Fixed discs 8 are fixedly installed on the four sides of the outer surface of the buffer seat 1. A buffer disc 801 is fixedly installed on the side of the fixed disc 8 away from the outer surface of the buffer seat 1. The buffer disc 801 and the fixed disc 8 are arranged in an intermittent combination. A pressure relief hole 802 is opened through the middle of one side of the outer surface of the fixed disc 8 and the buffer disc 801.

[0024] In use, the buffer box 6 can be fixed normally at the surface of the coal mine monitoring point. After the fixing is completed, the support rod 2 can be screwed into the assembly 101. At this time, the support rod 2 can be fixedly connected with the buffer seat 1. When the monitoring instrument 5 vibrates due to the movement and deformation of the coal mine surface during the monitoring process, the shock wave will be transmitted to the buffer box 6 and cause it to shake. At this time, the buffer seat 1 will shake synchronously. Under this situation, the telescopic rod 701 set between the buffer box 6 and the buffer seat 1 will move in extension and retraction according to the shaking direction of the buffer seat 1. At the same time, the telescopic rod 701 set on the side will be stretched by the shaking of the buffer seat 1. The running direction of the telescopic rod 701 will be adjusted by the movable shaft seat 7 under the stretching of the shocking of the buffer seat 1. When the telescopic rod 701 moves in extension and retraction synchronously with the shaking of the buffer seat 1, the compression spring 702 set on the telescopic rod 701 will repeatedly stretch and compress, thereby buffering the extension and retraction range of the telescopic rod 701 and further buffering the shaking range of the buffer seat 1.

[0025] At this time, the fixed plate 8 set between the buffer box 6 and the buffer seat 1 will squeeze the buffer plate 801 synchronously with the shaking of the buffer seat 1. Since the buffer plate 801 is made of rubber and is arranged in an intermittent combination with the fixed plate 8, the pressure is gradually reduced when the fixed plate 8 squeezes the buffer plate 801, and the pressure is further released through the pressure relief hole 802, thereby further buffering the buffer seat 1, reducing the shaking amplitude of the buffer seat 1 relative to the buffer box 6, so as to ensure the stability of the support rod 2, thereby ensuring the stability of the monitoring instrument 5 and achieving the effect of stable monitoring.

[0026] The above are merely embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principle of this utility model should be included within the scope of the claims of this utility model.
