Description

Technical Field

[0001] The utility model relates to the technical field of mine environment monitoring, in particular to a temperature and humidity monitoring device for coal mines. Background Technique

[0002] A coal mine is a spatial structure for obtaining coal resources through underground mining methods, including a production system composed of roadways, chambers, etc. In the mine, the coal seam is broken through different mining methods (such as longwall mining, blasting mining, etc.), and then transported to the ground for further processing. Coal lumps are coals with larger particle sizes formed after screening of raw coal and are commonly used for various purposes such as power generation and industrial boilers.

[0003] Due to the complex and changeable working environment of coal mines, the geological structure deep in the coal mines makes the interior of the mine often in a high-temperature and high-humidity state. The changes in temperature and humidity have a direct impact on the health and safety of miners. Therefore, it is often necessary to use temperature and humidity monitoring devices to monitor the temperature and humidity in the mine in real time.

[0004] Common temperature and humidity monitoring devices in the prior art include temperature probes. A temperature probe is a temperature monitoring device that integrates a sensor and a protective housing. When installing, the temperature monitoring device should be firmly fixed in the installation position to prevent it from moving or shaking. Generally, the bolt installation method is used for fixation.

[0005] However, the existing temperature and humidity monitoring devices need to be wired and connected to a control system or a display during installation, and need to be calibrated and debugged after installation. Therefore, the temperature and humidity monitoring devices need to be repeatedly disassembled and assembled. The existing method of fixing and installing by bolts has the problem of inconvenient disassembly and assembly, which reduces the working efficiency of disassembly and assembly operations such as debugging and calibration of temperature and humidity monitoring, so it is necessary to provide a temperature and humidity monitoring device for coal mines. Content of the Utility Model

[0006] The purpose of the utility model is to provide a temperature and humidity monitoring device for coal mines to solve the problems put forward in the above background technique.

[0007] To achieve the above object, the utility model provides the following technical solution: a temperature and humidity monitoring device for a coal mine shaft, including a temperature and humidity monitor and a mounting plate, wherein a fixing mechanism and a positioning mechanism are arranged on the mounting plate; an installation block is fixedly arranged on the mounting plate, an insertion block is fixedly arranged on the temperature and humidity monitor, a slot adapted to the insertion block is formed on the installation block, a clamping slot is formed on the insertion block, a fixing cylinder is fixedly arranged on the installation block, a sliding block is slidably connected in the fixing cylinder, a wedge-shaped clamping block adapted to the clamping slot is fixedly arranged at one end of the sliding block, the wedge-shaped clamping block slidably penetrates through the installation block and is clamped with the clamping slot, a connecting rod is fixedly arranged at the other end of the sliding block, and a first spring is sleeved on the connecting rod; fixing plates are fixedly arranged at both ends of the mounting plate, a sliding groove is formed on the fixing plate, a moving plate is slidably connected in the sliding groove, a bidirectional lead screw threadedly connected with the moving plate is rotatably connected in the sliding groove, a guide rod is slidably connected on the moving plate, a clamping block is fixedly connected at one end of the guide rod, and a second spring is sleeved on the guide rod.

[0008] Preferably, the connecting rod slidably penetrates through the fixing cylinder and is fixedly connected with a connecting block, and a pull ring is fixedly arranged on the connecting block.

[0009] Preferably, the first spring is fixedly arranged between the fixing cylinder and the sliding block.

[0010] Preferably, a limiting rod is fixedly arranged in the sliding groove, and the moving plate is slidably connected with the limiting rod.

[0011] Preferably, one end of the bidirectional lead screw rotatably penetrates through the sliding groove and is fixedly connected with a hand-twisting block, a limiting block is fixedly arranged at one end of the guide rod, and the second spring is fixedly arranged between the moving plate and the clamping block.

[0012] Preferably, a mounting part is fixedly arranged on the mounting plate.

[0013] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0014] 1) For this temperature and humidity monitoring device for a coal mine shaft, by inserting the insertion block into the slot, the wedge-shaped clamping block is extruded and moves towards the fixing cylinder. When the insertion block is completely inserted into the slot, the wedge-shaped clamping block is automatically clamped with the clamping slot under the rebounding action of the first spring, realizing the fixation of the temperature and humidity monitor. When disassembling, by pulling the pull ring, the connecting rod drives the wedge-shaped clamping block to retract into the fixing cylinder. At this time, the wedge-shaped clamping block is disengaged from the clamping slot, and then the insertion block can be pulled out of the slot to complete the rapid disassembly of the temperature and humidity monitor. The operation is simple and convenient, improving the working efficiency of debugging and calibration of the temperature and humidity monitor.

[0015] 2) The temperature and humidity monitoring device for the coal mine shaft can rotate the hand-twisting block to drive the bidirectional lead screw to rotate. Under the action of the thread, the two moving plates can drive the clamping blocks to move towards each other, so that the clamping blocks can firmly clamp both ends of the temperature and humidity monitor. At the same time, through the arrangement of the guide rod and the second spring, the clamping blocks can flexibly clamp the temperature and humidity monitor, improving the stability of the temperature and humidity monitor after installation and avoiding causing hard damage to the temperature and humidity monitor.

[0025] Specifically, by inserting the insertion block 403 into the slot 402, the wedge-shaped clamping block 407 is extruded and moves towards the fixing cylinder 405. When the insertion block 403 is completely inserted into the slot 402, the wedge-shaped clamping block 407 is automatically clamped with the clamping slot 404 under the rebounding action of the first spring 409, realizing the fixation of the temperature and humidity monitor 1. When disassembling, by pulling the pull ring 411, the connecting rod 408 drives the wedge-shaped clamping block 407 to retract into the fixing cylinder 405. At this time, the wedge-shaped clamping block 407 is disengaged from the clamping slot 404, and then the insertion block 403 is pulled out of the slot 402 to complete the rapid disassembly of the temperature and humidity monitor 1. The operation is simple and convenient, improving the working efficiency of debugging and calibration of the temperature and humidity monitor 1. Embodiment

[0026] Refer to Figure 4 , and on the basis of Embodiment 1, it is further obtained that fixing plates 501 are fixedly arranged at both ends of the mounting plate 2, a sliding groove 502 is formed on the fixing plate 501, a moving plate 503 is slidably connected in the sliding groove 502, a bidirectional lead screw 504 threadedly connected with the moving plate 503 is rotatably connected in the sliding groove 502, a guide rod 507 is slidably connected on the moving plate 503, a clamping block 510 is fixedly connected at one end of the guide rod 507, a second spring 509 is sleeved on the guide rod 507, a limiting rod 506 is fixedly arranged in the sliding groove 502, the moving plate 503 is slidably connected with the limiting rod 506, one end of the bidirectional lead screw 504 rotatably penetrates through the sliding groove 502 and is fixedly connected with a hand-tightening block 505, a limiting block 508 is fixedly arranged at one end of the guide rod 507, and the second spring 509 is fixedly arranged between the moving plate 503 and the clamping block 510.

[0027] Specifically, by rotating the hand-twisting block 505, the bidirectional lead screw 504 rotates. Under the action of the thread, the two moving plates 503 can drive the clamping blocks 510 to move towards each other, so that the clamping blocks 510 can firmly clamp both ends of the temperature and humidity monitor 1. At the same time, through the arrangement of the guide rod 507 and the second spring 509, the clamping blocks 510 can flexibly clamp the temperature and humidity monitor 1, improving the stability of the temperature and humidity monitor 1 after installation and avoiding hard damage to the temperature and humidity monitor 1.

[0028] In the actual operation process, first, the mounting plate 2 is installed in the mine using the mounting part 3. When the temperature and humidity monitor 1 needs to be installed, first insert the plug block 403 on the temperature and humidity monitor 1 into the slot 402 on the mounting block 401. When the plug block 403 is inserted into the slot 402, the wedge-shaped clamping block 407 is squeezed and moves towards the fixed cylinder 405, causing the first spring 409 to be squeezed into a compressed state. When the plug block 403 is completely inserted into the slot 402, the wedge-shaped clamping block 407 automatically pops out under the rebounding action of the first spring 409 and is clamped with the card slot 404 on the plug block 403, realizing the preliminary fixation of the temperature and humidity monitor 1. Then, by rotating the hand-twisting block 505, the bidirectional lead screw 504 rotates. Under the action of the thread, the two moving plates 503 can drive the clamping blocks 510 to move towards each other, so that the clamping blocks 510 can firmly clamp both ends of the temperature and humidity monitor 1. At the same time, through the arrangement of the guide rod 507 and the second spring 509, the clamping blocks 510 can flexibly clamp the temperature and humidity monitor 1, avoiding hard damage to the temperature and humidity monitor 1, and thus completing the installation of the temperature and humidity monitor 1, enabling the temperature and humidity monitor 1 to monitor the environment in the coal mine shaft in real time;

[0029] When the temperature and humidity monitor 1 needs to be removed, by rotating the rotating block 505 in the reverse direction, the bidirectional lead screw 504 drives the two clamping blocks 510 to move in the reverse direction towards each other, so that the clamping blocks 510 release the clamping and fixation of the temperature and humidity monitor 1. Then, by pulling the pull ring 411, the connecting rod 408 drives the wedge-shaped clamping block 407 to retract into the fixed cylinder 405. At this time, the wedge-shaped clamping block 407 is disengaged from the card slot 404, and then the plug block 403 is pulled out of the slot 402 to complete the rapid disassembly of the temperature and humidity monitor 1.
