Description

Technical Field

[0001] This utility model belongs to the field of mine safety monitoring technology, specifically a mine groundwater pressure monitoring device. Background Technology

[0002] Real-time monitoring of groundwater pressure is a core element in ensuring safe mining operations. Groundwater pressure data directly reflects the dynamic changes in groundwater bodies and plays a crucial role in predicting catastrophic events such as water inrush and surges.

[0003] If the monitoring device fails to provide early warning for disasters such as water inrush or gushing water, it may lead to catastrophic consequences. For example, a water inrush accident can instantly flood the roadway, causing underground workers to be trapped or even drown. If high-pressure groundwater rushes into the goaf, it may cause roadway collapse and equipment damage, directly threatening the mine's infrastructure.

[0004] In the prior art, mine groundwater pressure monitoring devices typically include pressure sensors, data acquisition modules, wireless transmission modules, and monitoring centers, with the pressure sensors transmitting the collected data to ground equipment via connecting cables.

[0005] Due to the complex underground environment of mines, equipment is susceptible to geological activity, mechanical vibration, and external impacts. Traditional equipment connection lines lack suitable devices for stable support and constraint guidance during long-term use. The connection lines experience constant sliding friction, leading to wear and even breakage of the cable sheath, thus shortening their lifespan. Furthermore, sudden external forces can damage the cables. Utility Model Content

[0006] The main purpose of this invention is to provide a mine groundwater pressure monitoring device that avoids damage to the connecting wires.

[0007] The groundwater pressure monitoring device for mines provided by this utility model includes a support assembly, a guide assembly, a wiring assembly, and a monitoring assembly. The support assembly includes a base plate and a support ring vertically fixed to the base plate. The guide assembly is disposed on the inner wall of the support ring and includes at least one set of guide frames and a guide roller rotatably installed in the guide frames. The circumferential surface of the guide roller is provided with an annular wire groove. The wiring assembly is disposed on the guide assembly and includes a lifting drive mechanism, an elastic element, and a pressure roller. The lifting drive mechanism is connected to the pressure roller through the elastic element, so that the pressure roller can move in the vertical direction and form a clamping gap with the wire groove of the guide roller. The monitoring assembly includes a water pressure monitor and a connecting wire. The connecting wire passes through the bottom of the support ring and sequentially passes through the wire groove of the guide roller and the clamping gap between the pressure roller and the guide roller.

[0008] In one embodiment of the above-mentioned device, the bottom of the support ring is connected to the base plate, and the base plate has vertically downward pins at the four corners.

[0009] In one embodiment of the above-described device, the guide frame is composed of a pair of horizontally parallel arc-shaped thick plates, and the guide rollers are mounted on their opposite sides via a rotating shaft.

[0010] In one embodiment of the above device, the lifting drive mechanism includes a side plate, a top plate, a screw, and a lifting plate; the two side plates are symmetrically fixed to the top two sides of the guide frame, and the top plate is horizontally connected to the upper end of the two side plates; the screw passes through the top plate and is connected to the lifting plate through a bearing, and a rotating handle is provided at the top of the screw.

[0011] In one embodiment of the above-mentioned device, the elastic element includes a spring sleeved on the outside of the telescopic rod, the upper end of the telescopic rod is fixed to the bottom of the lifting plate, the lower end is connected to an inverted U-shaped roller frame, and the pressure roller is installed at the bottom of the roller frame via a rotating shaft.

[0012] In one embodiment of the above-described device, the width of the pressure roller is smaller than the width of the guide roller guide groove.

[0013] In one embodiment of the above-mentioned device, four sets of guide components are evenly distributed circumferentially on the inner wall of the support ring, and radial reinforcing ribs are provided between the base plate and the support ring.

[0014] In one embodiment of the above-mentioned device, guide holes are provided on both sides of the lifting plate, which slide in cooperation with the vertical guide rod fixed on the top plate.

[0015] The beneficial effects of this utility model are as follows:

[0016] 1. Through the coordinated operation of the guide roller's wire groove and the pressure roller, a wrap-around clamping is formed, ensuring that the connecting wire is always in contact with the rotating guide surface, eliminating the direct sliding friction between the connecting wire and the fixed support ring in traditional devices, and reducing cable sheath wear.

[0017] 2. The elastic element composed of spring and telescopic rod provides flexible buffering during the clamping process of pressure roller, which not only ensures uniform distribution of clamping force, but also absorbs sudden external impact and avoids damage to the connecting wires caused by rigid clamping.

[0018] 3. The screw drive and elastic element are adjusted together. The lifting stroke of the pressure roller is controlled by rotating the handle. This can not only achieve stable clamping of the connecting wire to prevent shaking, but also quickly release the constraint for cable adjustment. Attached Figure Description

[0024] The relevant technical solutions will now be clearly and completely described with reference to the accompanying drawings of the embodiments of this utility model. Obviously, the described embodiments are only a part of the embodiments, and not all of the embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0025] like Figure 1 and Figure 2 As shown, the mine groundwater pressure monitoring device disclosed in this embodiment includes a support component, a guide component, a wiring component, and a monitoring component.

[0026] The support components include a base plate 1, a support ring 2, and a pin 3.

[0027] The base plate 1 is a square plate with vertically downward pins 3 at its four corners, which are used to insert into the ground to fix the device and prevent the device from shifting due to vibration, external impact and other factors in the complex environment of the mine.

[0028] A vertically installed cylindrical support ring 2 is provided at the center of the base plate 1, and the bottom of the support ring is connected to the base plate.

[0029] Radial reinforcing ribs are provided between the base plate 1 and the support ring 2 to improve the structural strength.

[0030] Four sets of guide components are uniformly welded circumferentially on the inner wall of the support ring 2. The guide components include guide frame 4 and guide roller 5.

[0031] Each set of guide frames 4 consists of a pair of horizontally parallel arc-shaped thick plates. Their inner arc surfaces are connected by arc plates and then welded and fixed to the support ring 2. Cylindrical guide rollers 5 are rotatably installed on the opposite sides of the two plates via a rotating shaft.

[0032] An annular guide groove is provided in the center of the circumferential surface of the guide roller 5 to accommodate the connecting wire 14.

[0033] The guide roller 5 can rotate freely around the pivot. When the connecting line 14 moves, the guide roller rotates accordingly to reduce friction.

[0034] like Figure 3 As shown, each guide assembly is also equipped with a wire harness assembly, which includes a side plate 6, a top plate 7, a screw 8, a bearing 9, a lifting plate 10, a roller frame 11, a pressure roller 12, a spring 15, and a telescopic rod 16.

[0035] The two side plates 6 are symmetrically fixed to the top two sides of the guide frame 4, and the top plate 7 is horizontally connected to the upper part of the two side plates.

[0036] The screw 8 runs vertically through the center of the top plate 7, with a handle 17 with friction texture at its top and the bottom end connected to the lifting plate 10 via a bearing 9.

[0037] The lifting plate 10 has guide holes on both sides, which slide in conjunction with the vertical guide rods fixed on the top plate 7.

[0038] like Figure 4 As shown, the bottom of the lifting plate 10 is equipped with an elastic element, which includes a telescopic rod 16 located at the center of the bottom of the lifting plate and a spring 15 sleeved on its outer side.

[0039] The lower end of the telescopic rod 16 is connected to the inverted U-shaped roller frame 11, and the bottom of the roller frame 11 is equipped with the pressure roller 12 via a rotating shaft.

[0040] The axis of the pressure roller 12 is parallel to that of the guide roller 5, and its width is less than the width of the guide groove of the guide roller 5, forming a clamping space corresponding to the guide groove.

[0041] The monitoring components include a water pressure monitor 13 and a connecting cable 14.

[0042] The water pressure monitor 13 is installed in the groundwater layer of the mine. Its connecting wire 14 passes sequentially through the bottom of the support ring 2, the wire groove of the guide roller 5, and the annular groove of the pressure roller 12, and finally connects to the external data acquisition module. The data acquisition module transmits the signal to the monitoring center via the wireless transmission module.

[0043] The working process of this device is as follows:

[0044] 1. Place the base plate 1 at the monitoring point and insert it into the ground fixing device using pins 3.

[0045] 2. The connecting wire 14 enters from the bottom of the support ring 2 and passes through the wire groove of each guide roller 5 in sequence. The guide roller moves and rotates freely with the connecting wire 14 to avoid direct friction between the connecting wire and the support ring.

[0046] 3. When in use, clamp the connecting line, rotate the handle 17 clockwise, the screw 8 drives the lifting plate 10 to move down, the spring 15 is compressed, and the pressure roller 12 descends to cooperate with the guide roller 5 to clamp the connecting line 14 and prevent it from shaking.

[0047] 4. When it is necessary to disassemble or adjust the connecting line, rotate the handle 17 counterclockwise, the lifting plate 10 moves up, the spring 15 rebounds, the pressure roller 12 rises, and the connecting line 14 is in a relaxed state for adjustment.

[0048] 5. When using this device for data monitoring, the water pressure monitor 13 collects groundwater pressure data in real time, transmits it to the data acquisition module via the connecting cable 14, and then sends it to the monitoring center via the wireless transmission module.

[0049] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although detailed descriptions have been provided 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.
