[0003] The existing coal mine safety monitoring system sensors are installed in the tunnels according to regulations, especially when it comes to mining working faces. Due to the complex on-site environment, the following situations occur:

[0004] 1. The sensor is easily infiltrated by water droplets in the coal mine, causing distortion of sensor data;

[0005] 2. The longer line of the sensor left outside is easily pulled, causing the sensor line to break.

[0006] Therefore, it is necessary to design a coal mine safety monitoring system sensor protection device to solve this problem.

[0007] The above contents are only used to assist in understanding the technical solution of the present invention, and do not constitute an admission that the above contents are the closest prior art. Utility Model Content

[0008] The purpose of the utility model is to provide a coal mine safety monitoring system sensor protection device to solve the problem mentioned in the above background technology that the existing coal mine safety monitoring system sensors are easily invaded by water droplets in the coal mine, causing sensor data distortion, and the existing coal mine safety monitoring system sensors have long lines left outside that are easily pulled, causing line breakage.

[0009] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0010] A sensor protection device for a coal mine safety monitoring system includes a sensor body, a wire member connected to one side of the sensor body, and further includes:

[0011] A waterproof unit, comprising a protection box disposed outside the sensor body for isolating the sensor body, and a box cover disposed at an opening of the protection box for closing the protection box;

[0012] The line arrangement unit includes a wire collection assembly arranged inside the protection box for collecting excess wire length outside the protection box, and a wire fixing rod arranged inside the protection box for supporting the wire between the wire collection assembly and the sensor body.

[0013] Furthermore, the waterproof unit also includes:

[0014] An extension pipe, disposed in the middle of the lower end of the protection box and connected to the interior of the protection box, for draining water droplets dripping on the outside of the protection box;

[0015] The pad lifting mechanism is arranged at the lower end of the protection box and is used to raise and position the sensor body.

[0016] Furthermore, the cushioning mechanism comprises:

[0017] A bracket, fixedly connected to the lower end of the interior of the protection box;

[0018] A pad is fixedly connected to the upper end of the bracket, the sensor body is placed on the upper end of the pad, and the upper end of the pad and located on both sides of the sensor body are respectively connected with a first baffle and a second baffle for limiting the sensor body;

[0019] A threaded hole is provided inside the second baffle;

[0020] A threaded rod is threadedly connected inside the threaded hole, and one end of the threaded rod is connected to a top block for tightening and positioning the sensor body.

[0021] Furthermore, the wire take-up assembly comprises:

[0022] The winding shaft is fixedly connected to the rear side of the protection box and is used to store the excess length of the wire outside the protection box.

[0023] Furthermore, the wire take-up assembly further comprises:

[0024] A guide sleeve, fixedly connected to the rear side of the protection box, wherein a guide hole is provided inside the guide sleeve;

[0025] A limit rod is slidably inserted in the guide hole and is used to limit the wire member wound on the outer side of the winding shaft. A limit block for limiting the limit rod is provided at one end of the limit rod and is located in the guide hole;

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0038] See also Figure 1-5 , the utility model provides a technical solution:

[0039] A sensor protection device for a coal mine safety monitoring system includes a sensor body 100, a wire member 1001 connected to one side of the sensor body 100, and further includes:

[0040] The waterproof unit 1 includes a protection box 11 disposed outside the sensor body 100 for isolating the sensor body 100, and a box cover 12 disposed at the opening of the protection box 11 for closing the protection box 11;

[0041] The line arrangement unit 2 includes a wire taking-up assembly 21 disposed inside the protection box 11 for storing excess length of the wire member 1001 outside the protection box 11 , and a wire fixing rod 22 disposed inside the protection box 11 for supporting the wire member 1001 between the wire taking-up assembly 21 and the sensor body 100 .

[0042] As an improvement, Figure 1-2 As shown, the waterproof unit 1 also includes:

[0043] An extension pipe 13 is provided in the middle of the lower end of the protection box 11 and is connected to the inside of the protection box 11, and is used to drain water drops dripping on the outside of the protection box 11;

[0044] The lifting mechanism 14 is disposed at the lower end of the protection box 11 and is used to raise and position the sensor body 100 .

[0045] Further, such as Figure 2 As shown, the cushion lifting mechanism 14 includes:

[0046] A bracket 142, fixedly connected to the lower end of the protection box 11;

[0047] A backing plate 141 is fixedly connected to the upper end of the bracket 142, the sensor body 100 is placed on the upper end of the backing plate 141, and a first baffle 143 and a second baffle 144 for limiting the sensor body 100 are respectively connected to the upper end of the backing plate 141 and located on both sides of the sensor body 100;

[0048] The threaded hole 1441 is provided inside the second baffle 144;

[0049] The threaded rod 145 is threadedly connected inside the threaded hole 1441 , and one end of the threaded rod 145 is connected to a top block 1451 for tightening and positioning the sensor body 100 .

[0050] As an improvement, Figure 3-5 As shown, the wire take-up assembly 21 includes:

[0051] The winding shaft 211 is fixedly connected to the rear side of the protection box 11 and is used to store the excess length of the wire member 1001 outside the protection box 11.

[0052] Furthermore, the wire take-up assembly 21 further includes:

[0053] A guide sleeve 212 is fixedly connected to the rear side of the protection box 11, and a guide hole 2121 is provided inside the guide sleeve 212;

[0054] The limiting rod 213 is slidably inserted in the guide hole 2121 and is used to limit the wire member 1001 wound on the outer side of the winding shaft 211. A limiting block 2131 for limiting the limiting rod 213 is provided at one end of the limiting rod 213 and is located in the guide hole 2121.

[0055] The tightening spring 214 is disposed inside the guide hole 2121 and is used for tightening the limiting block 2131 .

[0056] As an improvement, Figure 4 As shown, one end of the wire fixing rod 22 is provided with a wire clamping groove 221 for clamping the wire guide 1001, and the wire fixing rod 22 is provided with multiple groups along the extending direction of the wire guide 1001.

[0057] Such a design can ensure that the wire member 1001 between the winding shaft 211 and the sensor body 100 can be straightened and clamped in place, thereby preventing the wire member 1001 between the winding shaft 211 and the sensor body 100 from being entangled.

[0058] It should be supplemented that a wire outlet hole 111 for passing the wire guide 1001 from the inside of the protection box 11 to the outside is provided at the bottom of the protection box 11 and located on the outside of the wire guide 1001, and a hanging hook 101 for hanging the protection box 11 in the lane is provided at the upper end of the protection box 11.

[0059] It should be noted that: in the specific implementation process of the utility model, Figure 3-4As shown, the protection box 11 is first hung in the specified placement area through the hanging hook 101, and then the sensor body 100 is placed on the upper end of the pad 141, and the threaded rod 145 is rotated. The threaded rod 145 drives the top block 1451 to tighten the sensor body 100 under the action of the thread tangential force between the thread and the threaded hole 1441, so that the sensor body 100 is installed inside the protection box 11. When methane or carbon monoxide gas is diffused around the protection box 11, the methane or carbon monoxide will be dispersed into the protection box 11 through the extension pipe 13 and detected by the sensor body 100. When water droplets or water flows in the lane fall on the protection box 11, the water will flow along the protection box 11 to the extension pipe 13 and drip under the drainage action of the extension pipe 13, and the sensor body 100 located in the protection box 11 will not be immersed in the water flow, thereby achieving the effect of not being immersed in the water flow while ensuring that the sensor body 100 can work normally;

[0060] like Figure 4-5 As shown, during the wiring process of the sensor body 100, the utility model inserts one end of the wire member 1001 into the sensor body 100, and the other end passes through the protection box 11 along the wire outlet hole 111 and is connected to the power socket. For the excess wire member 1001 outside the protection box 11, the utility model can pull the excess wire member 1001 into the protection box 11 along the wire outlet hole 111, and then push the limit rod 213 so that the limit rod 213 moves along the guide hole 2121, and the tensioning spring 214 is compressed. At this time, the excess wire member 1001 is wound around the outside of the winding shaft 211, and the limit rod 213 is released. The tensioning spring 214 pushes the limit rod 213 to reset through the limit block 2131, so that the wire member 1001 wound around the outside of the winding shaft 211 is limited, avoiding the wire member 1001 from becoming loose outside the winding shaft 211, thereby being able to store the excess line and reduce the risk of the line being pulled.
