Description

Technical Field

[0001] The present invention relates to the technical field of underground equipment, and particularly to a fixing device for underground sensors. Background Art

[0002] During the safe production process in coal mines, accurate monitoring of underground environmental parameters is crucial, and wind speed is a key monitoring indicator among them. The magnitude and stability of wind speed directly affect the operation effect of the underground ventilation system, the dilution and emission of harmful gases, and the safety of workers. Therefore, accurately and stably measuring parameters such as underground wind speed is an important link in ensuring the safe production of coal mines.

[0003] Currently, the mine hook sensor is one of the commonly used devices for monitoring parameters such as underground wind speed. This type of sensor usually adopts a hanging method and is hung on a preset hook on the roadway wall to achieve fixed-point and quantitative monitoring of specific positions underground.

[0004] However, this hanging installation method has the problem of poor stability, which causes the sensor to be easily disturbed by various factors and shake in the underground environment. There are frequent movements of personnel and equipment in the underground roadway, and the resulting air flow changes, mechanical vibrations, etc. will cause the hanging sensor to shake. The shaking of the sensor will cause large fluctuations and errors in the measurement results, and cannot accurately reflect the actual wind speed situation underground. Inaccurate wind speed measurement data may mislead the adjustment and control of the ventilation system, affect the underground ventilation effect, and thus threaten the safe production of coal mines.

[0005] Secondly, the instability of the sensor may also cause the connection between it and the hook to become loose. During the long-term shaking process, there is a risk of the sensor falling. Once the sensor falls, it will not only cause damage to the equipment, increase the economic loss of the coal mine, but also interrupt the monitoring of parameters such as wind speed at this position, and it is impossible to timely grasp the changes in the underground environment, bringing potential hidden dangers to coal mine safety.

[0006] In addition, due to the poor stability of the sensor, the measurement results are inaccurate and prone to failures, and workers need to frequently check and debug the sensor to ensure its normal operation. This undoubtedly increases the labor intensity of workers, reduces work efficiency, and also increases the labor cost. Summary of the Invention

[0007] The present invention aims to solve at least one of the technical problems in the related art to some extent.

[0008] To this end, an embodiment of the present invention provides a fixing device for underground sensors with high stability and easy maintenance.

Detailed implementation manners

[0030] The embodiments of the present invention will be described in detail below. The examples of the embodiments are shown in the drawings. The embodiments described below by referring to the drawings are exemplary and are intended to explain the present invention, but should not be construed as limiting the present invention.

[0031] The downhole sensor fixing device according to an embodiment of the present invention will be described below with reference to the drawings.

[0032] As Figures 1 to 6 shown, the downhole sensor fixing device according to an embodiment of the present invention includes a housing 1 and an assembly component 2.

[0033] The housing 1 is in a cuboid shape. The length direction of the housing 1 is the first direction, that is, the front - rear direction as shown in Figure 3 ; the width direction of the housing 1 is the second direction, that is, the left - right direction as shown in Figure 3 .

[0034] The housing 1 is provided with a mounting hole 101. The housing 1 can be suspended on a preset hook on the roadway wall through the mounting hole 101. The housing 1 has a locking part 11 at the mounting hole 101. By fixing the part of the hook on the roadway wall located in the mounting hole 101 through the locking part 11, the problem that the sensor is loosened or even dropped due to shaking from the hook on the roadway wall in the traditional hanging method is effectively avoided, enhancing the connection stability between the entire fixing device and the roadway wall and laying a foundation for the stable installation of the sensor.

[0035] The bottom of the housing 1 has an opening through which the hook of the sensor is inserted into the housing 1. An assembly component 2 is arranged inside the housing 1. The assembly component 2 includes two first clamping members 21 arranged at intervals along the first direction of the housing 1. The two first clamping members 21 are used to jointly clamp the hook of the sensor. A fixing member 22 is detachably arranged between the two first clamping members 21, and the fixing member 22 is used to limit the hook of the sensor from falling.

[0036] It can be understood that this clamping method can prevent the sensor hook from shaking inside the housing 1, further improving the stability of the sensor installation. At the same time, the fixing member 22 is detachably arranged between the two first clamping members 21 and is used to limit the hook of the sensor from falling, ensuring the firmness of the sensor installation from another perspective.

[0037] For the downhole sensor fixing device according to the embodiment of the present invention, due to the improved installation stability, the interference factors received by the sensor during the measurement process are reduced, avoiding measurement result fluctuations and errors caused by shaking. The sensor can measure parameters such as downhole wind speed more accurately, providing reliable data support for the adjustment and control of the coal mine ventilation system, thereby ensuring the downhole ventilation effect and safe production.

[0038] The stable installation method reduces the possibility of the sensor falling, reduces the risk of equipment damage, and reduces the economic losses of the coal mine caused by equipment damage. In addition, due to the stable installation of the sensor, the measurement results are accurate and less prone to failure, reducing the frequency of inspection and debugging of the sensor by the staff, reducing the labor cost and labor intensity, and improving the work efficiency.

[0039] During installation, only need to hang the housing 1 on the hook on the roadway wall through the installation hole 101 and fix it with the locking part 11, then insert the hook of the sensor into the housing 1 through the opening at the bottom of the housing 1, and clamp it by the assembly component 2. During disassembly, remove the fixing member 22 and loosen the first clamping member 21, then the sensor can be taken out. The operation is simple and convenient, facilitating daily installation, maintenance and replacement.

[0040] Optionally, the housing 1 can be made of high-strength plastic or metal material. High-strength plastic has the advantages of light weight and corrosion resistance, and is suitable for the damp downhole environment; metal material has higher strength and stability, and can better protect the internal assembly component 2 and the sensor hook.

[0041] The size of the opening at the bottom of the housing 1 should be reasonably designed according to the size of the sensor hook, ensuring that the sensor hook can be inserted smoothly while preventing the opening from being too large to cause the sensor to shake inside the housing 1. The edge of the opening can be chamfered to avoid scratching the sensor hook.

[0042] In some embodiments, such as Figures 1 to 5As shown, the locking part 11 includes two fasteners spaced apart in the vertical direction. The fastener includes a bolt 111 and a nut 112 mounted on the bolt 111. The screw rod of the bolt 111 passes through the mounting hole 101. The head of the bolt 111 and the nut 112 are respectively located on both sides of the mounting hole 101, and the sizes of the head of the bolt 111 and the nut 112 are both larger than the size of the mounting hole 101.

[0043] It can be understood that after the hook on the roadway wall is inserted into the mounting hole 101, by moving the two fasteners to make the two fasteners in close contact with the hook, and then screwing the nut 112 on each fastener to fix the position of the fastener, the hook can be locked.

[0044] Furthermore, as Figures 3 to 5 shown, among the two fasteners, an arc-shaped slot 1111 is provided on the head of the bolt 111 of the upper fastener, so that the part of the hook on the roadway wall located in the mounting hole 101 is clamped in the arc-shaped slot 1111, thereby improving the locking effect.

[0045] In some embodiments, as Figures 2 to 6 shown, the two first clamping members 21 are defined as a first clamping member group. There are two groups of the first clamping member groups, and the two groups of the first clamping member groups are spaced apart in the second direction of the housing 1. The second direction is orthogonal to the first direction.

[0046] It can be understood that the two groups of the first clamping member groups are used to jointly clamp the hook of the sensor, increasing the clamping area of the hook of the sensor, thereby improving the stability of the installation of the sensor.

[0047] In some embodiments, as Figures 2 to 5 shown, the first clamping member 21 is slidably connected to the inner wall of the housing 1. For example, by installing a guide rail on the inner wall of the housing 1, the end of the first clamping member 21 is installed on the guide rail to enable the first clamping member 21 to slide along the first direction of the housing 1.

[0048] The assembly component 2 further includes a driving member 23. The driving member 23 is connected to the two groups of the first clamping member groups to drive the two first clamping members 21 in each group to approach or separate from each other. That is, the driving member 23 is used to drive the two groups of the first clamping member groups to clamp or loosen the hook of the sensor, improving the convenience of operation.

[0049] Optionally, as Figures 1 to 6As shown in the figure, the driving member 23 includes a driving disk 231 and four driving blocks 232. The four driving blocks 232 correspond to the four first clamping members 21 one by one and are slidably connected. The driving block 232 and the corresponding first clamping member 21 can slide relative to each other along the second direction of the housing 1. The driving disk 231 is rotatably connected to the housing 1, and the driving disk 231 is provided with guide grooves 2311 corresponding to the four driving blocks 232 one by one. In the radial direction of the driving disk 231, the distance between the guide groove 2311 and the center of the driving disk 231 gradually increases from the middle to both ends of the guide groove 2311. The driving block 232 is provided with a guide post 233, and the guide post 233 and the corresponding guide groove 2311 are slidably matched, so that the driving disk 231 rotates and drives the first clamping member 21 to slide through the driving block 232.

[0050] Four sliding grooves 102 are provided on the top cover of the housing 1. The four sliding grooves 102 correspond to the four guide posts 233 one by one. The guide post 233 and the corresponding sliding groove 102 are slidably matched, and the path of the sliding groove 102 and the path of the corresponding guide groove 2311 intersect in the vertical direction. The guide post 233 slidably penetrates through the sliding groove 102 and the guide groove 2311 in the vertical direction. A limiting block 234 is detachably provided at the upper end of the guide post 233, and the lower end surface of the limiting block 234 is in sliding contact with the upper end surface of the top cover of the housing 1.

[0051] It can be understood that when the driving disk 231 rotates, under the limiting action of the sliding groove 102 and the guide groove 2311, the driving disk 231 pushes the guide post 233 to slide along the extending direction of the sliding groove 102, thereby driving the driving block 232 to move. The driving block 232 drives the first clamping member 21 to slide, and at the same time, the driving block 232 and the first clamping member 21 also slide relative to each other, thereby realizing clamping or loosening the hook of the sensor.

[0052] Furthermore, as Figures 1 to 4 shown, a driving shaft 235 is provided at the center of the driving disk 231. The driving shaft 235 penetrates through the top cover of the housing 1 and is rotatably connected thereto. A handle 236 is provided at the upper end of the driving shaft 235. Since the driving disk 231 is located inside the housing 1, the rotation of the driving disk 231 is controlled by an external handle 236, which improves the convenience of operation.

[0053] In some embodiments, as Figures 1 to 6 shown, there are two mounting holes 101, and the two mounting holes 101 are respectively located on two end faces of the housing 1 in the first direction, so that the fixing device of the embodiment of the present invention can be fixed by a hook on the roadway wall passing through the two mounting holes 101, or two hooks respectively passing through the two mounting holes 101.

[0054] The assembly component 2 further includes two sets of second clamping member groups, which correspond to the two mounting holes 101 one by one. Each second clamping member group includes two second clamping members 24, which are slidably connected to the inner wall of the housing 1. The second clamping members 24 are slidable along the second direction of the housing 1. The two second clamping members 24 are used to jointly clamp the part of the hook on the roadway wall that passes through the mounting hole 101. By further clamping the hook on the roadway wall with the second clamping members 24, it is possible to prevent the fixing device in the embodiment of the present invention from rotating around the hook on the roadway wall and ensure the fixing effect.

[0055] The driving member 23 is connected to the two sets of second clamping member groups to drive the two second clamping members 24 in each group to approach or separate from each other. Specifically, the four driving blocks 232 correspond to the four second clamping members 24 one by one and are slidably connected. The driving block 232 and the corresponding second clamping member 24 can slide relative to each other along the first direction of the housing 1.

[0056] Thus, in the embodiment of the present invention, the driving member 23 is used to drive the first clamping member 21 and the second clamping member 24 to move synchronously, so as to fix the hook on the roadway wall and the hook of the sensor, which is convenient to operate.
