Description

Technical Field

[0001] The present invention relates to the technical field of mine geological environment monitoring, and more specifically, to a mine geological environment monitoring device and a monitoring method thereof. Background Art

[0002] In the field of mine geological environment monitoring, sampling and analysis of groundwater is a vital task. It can help understand the impact of mining activities on groundwater resources, including changes in water quality, water level fluctuations, and changes in hydrodynamic conditions, and provide key basis for the reasonable assessment and protection of the mine environment and the formulation of subsequent governance measures.

[0003] In traditional groundwater sampling methods, submersible pumps and water pumps are generally used. Due to its own structural characteristics, submersible pumps can withstand greater water pressure, so they are very suitable for groundwater extraction and sampling in deep wells (depth is usually greater than 200 meters). Water pumps are suitable for shallow wells (generally less than 10 meters, especially within the suction range). Therefore, when it is necessary to sample groundwater in a deep well, a submersible pump is required. The submersible pump drives the impeller to rotate through the motor, and uses the centrifugal force generated by the rotation of the impeller to lift the water to the ground after obtaining energy, thereby realizing the extraction and collection of groundwater.

[0004] However, when the submersible pump is actually used for groundwater sampling in mines, the high-speed rotation of the impeller will produce a strong stirring effect on the groundwater. This stirring can easily cause changes in suspended particles, dissolved gases and other components in the water sample. For example, fine sand particles originally evenly distributed in the groundwater will be mixed into the water sample in large quantities due to water flow disturbance, increasing the turbidity of the water sample, affecting the accurate detection of the concentration of dissolved substances in the water and other key indicators; at the same time, dissolved gases in the water may also escape due to stirring, changing the original chemical equilibrium state of the water sample, and ultimately making the collected water sample unable to truly reflect the original state of the groundwater, reducing the reliability of the test results, and not conducive to accurately grasping the actual properties of groundwater under the mining geological environment. Therefore, we designed a monitoring device and monitoring method for the mining geological environment. Summary of the invention

[0042] Please refer to Figure 2 , Figure 3The driving mechanism includes a support frame 304, the support frame 304 is fixedly connected to the sealing box 1, a motor 303 is fixedly installed on the top of the sealing box 1, the power output shaft of the motor 303 passes through the support frame 304, a first rotating shaft 305 is fixedly installed on the power output shaft of the motor 303, a second bevel gear 308 is fixedly installed on the first rotating shaft 305, two first bevel gears 306 are meshed on the second bevel gear 308, a first reciprocating screw rod 307 is fixedly connected to the first bevel gear 306, the first reciprocating screw rod 307 passes through the support frame 304 and is rotatably connected to the support frame 304, a rotating seat 320 is rotatably installed on the first reciprocating screw rod 307, the rotating seat 320 is fixedly connected to the mounting tube 301, and a driving component is threadedly connected to the first reciprocating screw rod 307.

[0043] Please refer to Figure 8 A plurality of slide grooves 309 are formed through the mounting tube 301, and the driving assembly includes a driving frame 302, the driving frame 302 matches the slide grooves 309 and is slidably connected to the mounting tube 301, the driving frame 302 is threadedly connected to the first reciprocating screw rod 307, and a third electromagnet 323 and a fourth electromagnet 324 are fixedly connected to the driving frame 302, the third electromagnet 323 and the first electromagnet 311 are magnetically repelled from each other, and the fourth electromagnet 324 and the second electromagnet 319 are magnetically repelled from each other.

[0044] Please refer to Figure 2 A water pipe 310 is fixedly connected to the top of the installation pipe 301, and the water pipe 310 is connected to an external water source storage box.

[0045] The present invention drives two pistons to move up and down through the sliding rod 318, and uses the two pistons to extract groundwater into the water source storage box on the ground to achieve groundwater sampling. The specific scheme is as follows: first, the water pipe 310 is connected to the external water source storage box, and then, one end of the rope is firmly tied to the appropriate position of the sealed box 1 (usually with a special lifting ring and other structures), and then the sealed box 1 is slowly placed to a suitable depth below the predetermined water level by manpower or with the help of a small simple winch and other equipment. Finally, by starting the motor 303, the motor 303 will drive the drive frame 302 to move, and the drive frame 302 will drive the third electromagnet 323 and the fourth electromagnet 324 to move. Since the third electromagnet 323 and the fourth electromagnet 324 are installed at different positions on the drive frame 302, the third electromagnet 323 and the fourth electromagnet 324 will be The fourth electromagnet 324 first acts on the second electromagnet 319 to move the slide bar 318 upward, so that the second piston 317 will also move upward. The upward movement of the second piston 317 will squeeze the water source in the left cavity of the fixed box 314. Since the first check valve 313 and the second check valve 316 on the left and right sides of the fixed box 314 are both directed from bottom to top, the squeezed water source will enter the water pipe 310 through the first check valve 313, and will be transported to the external water source storage box through the water pipe 310 for storage, thereby completing the groundwater sampling. During the upward movement of the second piston 317, it will also act on the cavity on the right side of the fixed box 314. With the help of the suction force of the second piston 317 moving upward, the second check valve 316 on the right side of the fixed box 314 can be opened to extract the water source outside and store it in the cavity on the right side of the fixed box 314.

[0046] After the fourth electromagnet 324 has acted on the second electromagnet 319, the third electromagnet 323 will act on the first electromagnet 311 to move the slide bar 318 downward. The downward movement of the slide bar 318 will cause the second piston 317 to discharge the water source in the cavity on the right side of the fixed box 314 into the water pipe 310, and then open the second check valve 316 on the left side of the fixed box 314 to extract the water source into the cavity on the left side of the fixed box 314 for storage. Since the driving frame 302 moves back and forth left and right, the water source can be extracted all the time. In addition, the above-mentioned method for extracting groundwater only requires the interaction between the electromagnets and has nothing to do with the impeller, which reduces the agitation of the groundwater and reduces the risk of changes in components such as suspended particles and dissolved gases in the water sample, which helps to obtain groundwater samples that are closer to the original state. In addition, the power for pumping water has nothing to do with the driving force of the motor 303. In this way, when the device works at different depths of groundwater, it only needs to control the magnetic force change of the electromagnet, which effectively solves the problem of needing to replace submersible pumps of different specifications when working with groundwater at different depths.

[0047] Please refer to Figure 5A conduit 315 is fixedly installed inside the fixed box 314, and the top of the conduit 315 is connected to the piston box 322, and the conduit 315 is slidably connected to the second piston 317; when the sliding rod 318 drives the second piston 317 to move up and down, it will also drive the second piston 317 to move up and down. The upward movement of the second piston 317 will increase the suction force in the cavity on the right side of the fixed box 314, so that it can absorb liquid faster, and the downward movement of the second piston 317 will squeeze the piston box 322 and press down the cavity on the right side of the fixed box 314, thereby accelerating the discharge of water in the cavity on the right side of the fixed box 314, thereby accelerating the extraction speed in the original groundwater extraction process.

[0048] Please refer to Figure 5 , Figure 6 , Fig.10 As shown, a second suction pipe 206 is fixedly connected to the bottom of the mounting tube 301, the first suction pipe 201 is slidably connected to the second suction pipe 206, the first suction pipe 201 is fixedly connected to a fixing plate 202, a flexible filter net 207 is fixedly installed inside the first suction pipe 201, a counterweight is fixedly connected to the flexible filter net 207, a pull rope 204 is fixedly connected to the counterweight, the pull rope 204 is fixedly connected to the second electromagnet 319, an auxiliary wheel 203 is provided on the pull rope 204, a mounting plate 205 is rotatably connected to the auxiliary wheel 203, and the mounting plate 205 is fixedly connected to the mounting tube 301.

[0049] The setting of the pull rope 204 and the flexible filter net 207 can intercept mud, particles and suspended matter in the process of the slide bar 318 moving up and down to extract water. The up and down movement of the slide bar 318 will also continuously pull the flexible filter net 207, causing the mud, particles and suspended matter filtered on the filter net to shake and fall off, thereby avoiding blockage and affecting the extraction of water.

[0051] The setting of the threaded frame 404 can drive the first suction pipe 201 to move downward when the motor 303 is reversed, so that the first suction pipe 201 can be extended to other places to extract water for testing, and the downward movement of the first suction pipe 201 will drive the flexible filter net 207 to move together, so that the pull rope 204 increases the pulling of the flexible filter net 207, so that the flexible filter net 207 can further change its shape, so as to better clean the attached mud, particles, and suspended matter, and can also extract water while the first suction pipe 201 is constantly moving up and down, so as to achieve mixed sampling and testing of water sources in an area.

[0052] Please refer to Fig.11 The monitoring method of the mining geological environment monitoring device comprises the following steps:

[0054] S2. Tie one end of the rope firmly to the sealed box 1, and slowly lower the sealed box 1 to a suitable depth below the predetermined water level by means of a winch;

[0055] S3, control the motor 303 to rotate forward, and the motor 303 drives the slide bar 318 to move up and down through the third electromagnet 323 and the fourth electromagnet 324 to extract groundwater and transport it to the water pipe 310, and then transport it to the external water source storage box through the water pipe 310 to complete the sampling;

[0056] S4, control the motor 303 to reverse, the motor 303 changes the position of the first suction pipe 201 through the threaded frame 404, while extracting water, and transports the water to the water pipe 310, and then transports the water to the external water storage box through the water pipe 310, completing the sampling;

[0057] S5, turn off the motor 303, and take the sealing box 1 out of the groundwater by the winch in S2.

[0058] Working principle: first connect the water pipe 310 with the external water source storage box, then tie one end of the rope firmly to the appropriate position of the sealed box 1, usually with a special lifting ring and other structures, and then slowly put the sealed box 1 into the appropriate depth below the predetermined water level by manpower or with the help of a small simple winch and other equipment, and finally, by starting the motor 303, the motor 303 drives the first rotating shaft 305 to rotate, and the first rotating shaft 305 will drive the first reciprocating screw rod 307 to rotate through the first bevel gear 306 and the second bevel gear 308, and the first reciprocating screw rod 307 will rotate. The screw rod 307 drives the driving frame 302 to move. The movement of the driving frame 302 will cause the third electromagnet 323 and the fourth electromagnet block 324 to move. When the fourth electromagnet block 324 acts on the second electromagnet block 319, the slide bar 318 drives the second piston 317 and the first piston 312 to move upward. In this way, the second piston 317 will discharge the water source in the left cavity of the fixed box 314 to the water pipe 310.
