Description

Technical Field

[0001] The present invention relates to the technical field of geological exploration, and specifically, to a method and system for detecting old goaf water in a mining area. Background Art

[0002] Old goaf water (also known as accumulated water in the goaf) is an accumulated water area formed in coal mines or metal mines due to historical mining activities, which is characterized by strong concealment and high water inrush risk. The detection method needs to combine geological, hydrological and engineering means. Among them, the geophysical exploration method belongs to one of the common detection methods, including: transient electromagnetic method, high-density resistivity method, seismic reflection wave method, and ground penetrating radar, etc. Among them, the high-density resistivity method is a geophysical exploration method based on the resistivity difference of rock and soil, mainly used to detect the electrical structure of underground media, and is widely used in the fields of old goaf water detection, geological structure investigation, mineral exploration, engineering geological investigation, etc. Its core principle is to infer the distribution of underground rock layers, aquifers or cavities by measuring the apparent resistivity of underground media.

[0003] Currently, when using the high-density resistivity method for old goaf water detection work, first, wiring needs to be carried out. Multiple electrodes are inserted into the ground at a preset point distance, and a data acquisition line is used to connect multiple electrodes. There is a preset card slot in the cable. When connecting, only need to snap the card slot onto the electrode. After detecting one survey line, then conduct the detection of the next survey line. In the prior art, when inserting the measurement electrode into the ground, it is mostly carried out by direct insertion. When encountering a relatively hard geological area, it is necessary to manually hold a hammer and hammer the electrode into the ground. Due to the large number of electrodes to be arranged, it is necessary to manually bend down and hammer repeatedly, and it is necessary to move the relatively heavy data acquisition line, which is troublesome to operate, has a large labor intensity, and low work efficiency.

[0004] After retrieval, an existing patent (publication number: CN118688863A) is a high-density resistivity instrument. When it is working, the hydraulic cylinder is started, and the hydraulic cylinder pushes the sliding plate to slide down on the support rod. The sliding plate drives the support block to move downward, the support block drives the fixed plate to move downward, the fixed plate drives the rotating block to move downward, and the measuring plate is heated by a heating rod. Then the rotating disk is rotated. Under the joint action of the rotating block, the clamping block and the connecting block, the measuring screw rod is driven to rotate, so that the heated measuring screw rod can be quickly screwed into the frozen soil. However, in the above scheme, due to the large number of electrodes to be arranged, it is necessary for workers to continuously carry out the feeding work of the measuring screw rod, and for each soil insertion work, the worker needs to rotate the rotating disk to make the measuring screw rod rotate, which needs to be well coordinated with the downward push of the hydraulic cylinder, and the operation difficulty is large.

[0017] A method for detecting old empty water in a mining area comprises the following steps:

[0018] Step 1: insert multiple electrode rods prepared in advance into the installation grooves provided on the outer periphery of the installation platform, and place the end caps on the upper end of the perforated rubber pads to support the end caps through the perforated rubber pads;

[0019] Step 2: When the electrode rod is inserted into the foundation to be measured, the moving trolley is pushed to move the entire device to the location to be measured. After that, the power is turned on and the motor is started. The motor drives the rotating mechanism to rotate, so that the rotating mechanism drives the transmission mechanism, prompting the lifting frame on the transmission mechanism to drive the lifting rod to move up and down reciprocatingly;

[0020] Step 3: During the process of the rotating mechanism rotating and driving the transmission mechanism, the toggle mechanism can be driven by the linkage mechanism, and the toggle mechanism during the driving process can intermittently rotate the installation component at the same angle;

[0021] Step 4: When the linkage sleeve on the linkage mechanism penetrates the interior of the installation slot, the electrode rod is inserted into the ground.

As the lifting shaft continues to move upward, the limit ring pushes the round block upward, so that the round block revolves clockwise along the inner side of the arc frame through the traction rope to the T-block;

At the same time, the data acquisition line is continuously relaxed by the winder so that the data acquisition line is laid along the electrode rod arrangement path.

In the present invention, a motor, a rotating mechanism, a transmission mechanism, a linkage mechanism, a toggle mechanism and a mounting assembly are provided, wherein the outer periphery of the mounting platform on the mounting assembly can simultaneously arrange a plurality of electrode rods in a stable circular array, when the rotating mechanism is driven to rotate by the motor, the rotating mechanism can drive the transmission mechanism, and the driven transmission mechanism can drive the toggle mechanism through the linkage mechanism, and the structural design of the toggle mechanism enables the worm that rotates multiple circles to drive the worm wheel on the transmission mechanism to rotate one circle and the transmission frame to complete a lifting movement, and can alternately realize the rotation of the mounting assembly and the pressing work of the pushing column on the electrode rod, so that the mounting assembly can be intermittently rotated at the same angle, so that the mounting grooves provided on the outer periphery of the mounting platform can be replaced in position, so that the electrode rods in different mounting grooves can be pressed down into the soil by the pushing column on the linkage mechanism, so as to realize the automatic material filling and soil insertion work of the electrode rods, and there is no need for manual repeated bending to arrange the electrode rods by hammering, which greatly reduces the labor degree of personnel and improves work efficiency;

[0027] 2. In the present invention, when the push column extends into one of the installation slots, the insert sheet will be inserted into the sheet slot, and the push column pushes down the end cover, so that the end cover passes through the perforated rubber pad and slides down along the inner wall of the installation slot. The setting of the perforated rubber pad can temporarily stably place the electrode rod inside the installation slot. Since the rotating mechanism can drive the push column to rotate, the end cover can be driven to rotate through the insert sheet, so that the electrode rod can rotate while sliding down, so that the electrode rod can be simply and quickly rotated and inserted into the foundation;

[0028] 3. In the present invention, a mobile cart is provided, and a winder is provided on the top of the mobile cart. As the entire device continues to move forward, multiple electrode rods can be inserted and arranged along the travel path, and the data acquisition line is electrically connected to the electrode rod through an electrode clamp or the like. As the device moves forward, the data acquisition line is continuously loosened adaptively through the winder, so that the data acquisition line is laid along the electrode rod arrangement path, which greatly improves work efficiency and reduces the burden on staff.

[0064] Specifically, the toggle mechanism 8 includes an arc frame 802 fixedly connected to one side of the mounting bracket 7 and a lifting shaft 801 fixedly connected to the bottom end of the first connecting seat 602. The bottom end of the lifting shaft 801 is fixedly connected to a ball 809. A T-shaped cavity 803 is provided inside the arc frame 802. A T-shaped block 805 is provided on a sliding sleeve inside the T-shaped cavity 803. A return spring 808 is connected between the T-shaped block 805 and one end inside the arc frame 802. A traction rope 809 is provided on the sliding sleeve inside the ball 809. 04, one end of the traction rope 804 extends to the inside of the arc frame 802 and is connected to the outer wall of the T-block 805, and the outer wall of the T-block 805 located outside the arc frame 802 is provided with a shift block 806 that cooperates with the tooth block group 904, and the upper side of the junction between the shift block 806 and the T-block 805 is rotatably connected through the rotating shaft 807, and a torsion spring is provided between the shift block 806 and the T-block 805 on one side of the rotating shaft 807, which is used to provide a clockwise flipping force to the shift block 806.

[0065] Furthermore, a round block 811 is provided on the inner sliding sleeve of the lifting shaft 801, a connecting spring 812 is connected between the round block 811 and the top of the lifting shaft 801, one end of the traction rope 804 is connected to the round block 811, a limiting ring 810 is fixedly connected to the inner wall of the lifting shaft 801, and the traction rope 804 slides through the inside of the limiting ring 810.

[0066] In this embodiment, during the rotation of the worm 402, the prism 607 can be driven to rotate, the prism 607 drives the linkage sleeve 604 to rotate, the linkage sleeve 604 drives the push column 605 and the insert 606 at the bottom of the push column 605 to rotate, and at the same time, due to the rotation of the worm 402, the worm wheel 502 can be driven to rotate, and when the rotating column 505 revolves downward, the lifting rod 504 can be driven downward by the lifting frame 503, the lifting rod 504 drives the L-shaped frame 601 to move downward, and the L-shaped frame 601 drives the first connecting seat 602 and the second connecting seat 603 moves downward, and during the downward movement of the second connecting seat 603, the linkage sleeve 604 can be driven to slide down, so that the pushing column 605 extends into one of the installation grooves 902, and the insert 606 is inserted in the sheet groove 102. The pushing column 605 pushes the end cover 101 downward, so that the end cover 101 passes through the perforated rubber pad 903 and slides down along the inner wall of the installation groove 902. When the pushing column 605 rotates, the end cover 101 can be driven to rotate through the insert 606. Therefore, the electrode rod 1 rotates while sliding down, so that the electrode rod 1 can be simply and quickly rotated and inserted into the foundation.

[0067] In this embodiment, when the linkage sleeve 604 passes through the interior of the installation slot 902, the electrode rod 1 is completely inserted into the ground. Figure 2 and Figure 3, the lifting frame 503 moves to the lowermost position. As the worm wheel 502 continues to rotate, the lifting frame 503 drives the lifting rod 504 to move upward, prompting the L-shaped frame 601 to drive the first connecting seat 602 and the second connecting seat 603 to move upward. The second connecting seat 603 withdraws the push column 605 from the installation groove 902 through the linkage sleeve 604. When the push column 605 has not been completely withdrawn from the installation groove 902, during the process of the first connecting seat 602 driving the lifting shaft 801 to move upward, referring to Figure 7 , Figure 8 and Figure 9 , due to the T-shaped block 805 being restricted by the pulling force of the return spring 808, initially, during the upward movement of the lifting shaft 801, the pulling force cannot overcome the elastic force of the return spring 808, and the end of the traction rope 804 connected to the T-shaped block 805 remains stationary, causing the connecting spring 812 to be gradually stretched until the round block 811 abuts against the limiting ring 810 moving upward with the lifting shaft 801, causing the push column 605 to be exactly completely withdrawn from the installation groove 902. As the lifting shaft 801 continues to move upward, the limiting ring 810 pushes the round block 811 upward, overcoming the elastic force of the return spring 808, causing the round block 811 to revolve clockwise along the inner side of the arc-shaped frame 802 through the traction rope 804 to the T-shaped block 805.

[0068] In this embodiment, when the T-shaped block 805 revolves clockwise, the return spring 808 is stretched, and the dial block 806 pushes the tooth block group 904. At this time, the side of the dial block 806 away from the rotating shaft 807 abuts against the outer wall of the T-shaped block 805 and will not be flipped through the rotating shaft 807. Therefore, the tooth block group 904 can be pushed by the dial block 806, causing the mounting table 901 to rotate by a certain angle, so that the electrode rod 1 inside the next mounting groove 902 revolves to directly below the push column 605. Then, the push column 605 that continues to move downward rotates and pushes down the electrode rod 1 inside this mounting groove 902. When the first connecting seat 602 drives the lifting shaft 801 to move downward at this time, the originally abutted limiting ring 810 and the round block 811 are separated. Under the action of the return spring 808, the T-shaped block 805 revolves and resets. At this time, under the action of the rotating shaft 807, the dial block 806 will be flipped counterclockwise when it abuts against the tooth block group 904 and will not cause the mounting table 901 to rotate through the tooth block group 904.

[0069] Working principle and usage process: S1: Insert a plurality of pre-prepared and put-into-use electrode rods 1 into the installation grooves 902 opened on the outer periphery of the mounting table 901, and place the end cover 101 on the upper end of the perforated rubber pad 903. The perforated rubber pad 903 supports the end cover 101, enabling the mounting table 901 to be stably placed inside the installation groove 902;

[0070] S2: When inserting the electrode rod 1 into the foundation to be measured, push the moving trolley 12 to move the entire device to the location to be measured. At this time, the pressing column 605 is directly above one of the installation slots 902. Then, turn on the power supply and start the motor 3. The motor 3 drives the rotating rod 401 to rotate through its output shaft. The rotating rod 401 drives the worm 402 to rotate. The worm 402 drives the worm wheel 502 to rotate around the connecting column 501. During the rotation of the worm wheel 502, the rotating column 505 can be driven to revolve through the rectangular frame 506. When the rotating column 505 revolves, it can push the lifting frame 503, causing the lifting frame 503 to drive the lifting rod 504 to move up and down reciprocally;

[0071] S3: During the rotation of the worm 402, it can drive the prism column 607 to rotate. The prism column 607 drives the linkage sleeve 604 to rotate. The linkage sleeve 604 drives the pressing column 605 and the insert piece 606 at the bottom of the pressing column 605 to rotate. At the same time, due to the rotation of the worm 402, the worm wheel 502 can be driven to rotate. When the rotating column 505 revolves downward, it can drive the lifting rod 504 to move downward through the lifting frame 503. The lifting rod 504 drives the L-shaped frame 601 to move downward. The L-shaped frame 601 drives the first connecting seat 602 and the second connecting seat 603 to move downward. During the downward movement of the second connecting seat 603, it can drive the linkage sleeve 604 to slide downward, causing the pressing column 605 to extend into one of the installation slots 902. The insert piece 606 is inserted into the piece slot 102. The pressing column 605 pushes the end cover 101 downward, causing the end cover 101 to pass through the rubber gasket with holes 903 and slide along the inner wall of the installation slot 902. Since the pressing column 605 can drive the end cover 101 to rotate through the insert piece 606 when rotating, therefore, the electrode rod 1 rotates while sliding downward, so that the electrode rod 1 can be simply and quickly rotated and inserted into the foundation;

[0072] S4: When the linkage sleeve 604 penetrates into the installation slot 902, the ground insertion of the electrode rod 1 is completed. At this time, refer to Figure 2 and Figure 3 , the lifting frame 503 moves to the lowest position. As the worm wheel 502 continues to rotate, the lifting frame 503 drives the lifting rod 504 to start moving upward, prompting the L-shaped frame 601 to drive the first connecting seat 602 and the second connecting seat 603 to move upward. The second connecting seat 603 pulls out the pressing column 605 from the installation slot 902 through the linkage sleeve 604;

[0073] S5: When the pressing column 605 has not been completely pulled out of the installation slot 902, during the upward movement of the first connecting seat 602 driving the lifting shaft 801, refer to Figure 7 , Figure 8 and Figure 9, due to the tensile force limitation of the reset spring 808 on the T-shaped block 805, initially, during the upward movement of the lifting shaft 801, the tensile force cannot overcome the elastic force of the reset spring 808, and the end of the traction rope 804 connected to the T-shaped block 805 remains stationary, causing the connecting spring 812 to gradually stretch. It is not until the round block 811 abuts against the limiting ring 810 that moves upward with the lifting shaft 801 that the pushing column 605 is exactly completely withdrawn from the installation groove 902. As the lifting shaft 801 continues to move upward, the limiting ring 810 pushes the round block 811 upward, overcoming the elastic force of the reset spring 808, causing the round block 811 to revolve clockwise along the inner side of the arc-shaped frame 802 on the T-shaped block 805 through the traction rope 804;

[0074] S6: When the T-shaped block 805 revolves clockwise, the reset spring 808 stretches, and the shifting block 806 pushes the tooth block group 904. At this time, the side of the shifting block 806 away from the rotating shaft 807 abuts against the outer wall of the T-shaped block 805 and will not flip through the rotating shaft 807. Therefore, the shifting block 806 can push the tooth block group 904, causing the mounting table 901 to rotate by a certain angle, so that the electrode rod 1 inside the next mounting groove 902 revolves to directly below the pushing column 605. Then, referring to S3, continue to rotate and push down the electrode rod 1 inside this mounting groove 902 through the downward-moving pushing column 605. When the first connecting seat 602 drives the lifting shaft 801 to move downward at this time, the originally abutting limiting ring 810 and round block 811 separate. Under the action of the reset spring 808, the T-shaped block 805 revolves back to its original position. At this time, under the action of the rotating shaft 807, the shifting block 806 will flip counterclockwise when abutting against the tooth block group 904 and will not cause the mounting table 901 to rotate through the tooth block group 904;

[0075] S7: As the entire device continues to move forward, a plurality of electrode rods 1 can be inserted and arranged along the traveling path. The data acquisition line 10 is electrically connected to the electrode rods 1 through electrode clips or the like. As the device moves forward, the take-up reel 11 continuously relaxes the data acquisition line 10 appropriately, so that the data acquisition line 10 is laid along the arrangement path of the electrode rods 1.

10. A method for detecting old goaf water in a mining area, which uses any one of the old goaf water detection systems as claimed in claims 1-9, characterized in that, The following steps are involved: Step 1: inserting a plurality of electrode rods (1) prepared in advance and put into use into the mounting grooves (902) provided on the outer periphery of the mounting platform (901), and placing the end cover (101) on the upper end of the perforated rubber pad (903), and supporting the end cover (101) through the perforated rubber pad (903); Step 2: When the electrode rod (1) is inserted into the foundation to be measured, the moving trolley (12) is pushed to move the entire device to the location to be measured. After that, the power supply is turned on and the motor (3) is started. The motor (3) drives the rotating mechanism (4) to rotate, so that the rotating mechanism (4) drives the transmission mechanism (5), prompting the lifting frame (503) on the transmission mechanism (5) to drive the lifting rod (504) to move up and down reciprocatingly; Step 3: When the rotating mechanism (4) rotates and drives the transmission mechanism (5), the toggle mechanism (8) can be driven by the linkage mechanism (6), and the toggle mechanism (8) can intermittently rotate the mounting assembly (9) at the same angle during the driving process; Step 4: When the linkage sleeve (604) on the linkage mechanism (6) penetrates the interior of the installation groove (902), the electrode rod (1) is inserted into the ground. After that, under the action of the transmission mechanism (5), the L-shaped frame (601) drives the first connecting seat (602) and the second connecting seat (603) to move upward, and the second connecting seat (603) extracts the pushing column (605) from the installation groove (902) through the linkage sleeve (604); Step 5: When the push column (605) has not been completely pulled out of the installation groove (902), the pulling force cannot overcome the elastic force of the return spring (808), and the end of the traction rope (804) connected to the T-block (805) remains stationary until the round block (811) conflicts with the limit ring (810) that moves upward with the lifting shaft (801), so that the push column (605) is completely pulled out of the installation groove (902). As the lifting shaft (801) continues to move upward, the limit ring (810) pushes the round block (811) upward, so that the round block (811) revolves clockwise along the inner side of the arc frame (802) on the T-block (805) through the traction rope (804); Step 6: When the T-shaped block (805) rotates clockwise around its axis, the shifting block (806) pushes the tooth block group (904). At this time, the side of the shifting block (806) away from the rotating shaft (807) abuts against the outer wall of the T-shaped block (805) and will not flip through the rotating shaft (807). Therefore, the tooth block group (904) can be pushed by the shifting block (806), causing the mounting table (901) to rotate by a certain angle, so that the electrode rod (1) inside the next mounting groove (902) rotates to a position directly below the pressing column (605). Then, referring to Step 3, the electrode rod (1) inside this mounting groove (902) is rotated and pushed downward. Step 7: As the entire device continues to move forward, multiple electrode rods (1) can be inserted and arranged along the traveling path. At the same time, the take-up reel (11) continuously relaxes the data acquisition line (10) appropriately, so that the data acquisition line (10) is laid along the arrangement path of the electrode rods (1).
