Description

Technical Field

[0001] The invention belongs to the technical field of geophysical prospecting instruments, and in particular relates to a portable coalfield geological and geophysical exploration data acquisition device. Background Art

[0002] Before mining, geophysical exploration data acquisition equipment is needed to explore the geology in the designated area to determine whether there is a coalfield. Generally, geophysical metal rods are inserted into the ground to explore the geology.

[0003] The Chinese invention application with application number "CN116643326A" discloses a geophysical instrument for geological exploration. Through the cooperation of a base row, a side seat and a first motor, the geophysical metal rod can be intermittently pushed out through the reciprocating movement of the anti-stuck table. The first motor cooperates with the pneumatic telescopic rod to drive the rotation of the geophysical metal rod through the cooperation of the annular gear plate and the small gear plate, so as to realize the rotation and downward movement of the geophysical metal rod. Compared with the manual hammering fixation of the traditional geophysical metal rod, the geophysical metal rod can be automatically intermittently dropped and inserted, saving manpower while avoiding the damage that may be caused by the geophysical metal rod being hammered; Although the above application can fix the geophysical metal rod without using manual hammering to avoid damage to the geophysical metal rod, the soil on some outdoor ground is relatively dense. At this time, inserting the geophysical metal rod into the ground may cause greater friction between the geophysical metal rod and harder soil blocks or stones inside the soil blocks, making the geophysical metal rod not descend smoothly, thereby causing the geophysical metal rod to overheat and be damaged during the descent.

[0028] The spring assembly 31 is composed of a strong spring 311 and a damping telescopic rod 312 . The strong spring 311 is located at the center of the inner cavity of the damping telescopic rod 312 .

[0029] A plug 7 is inserted into the top of the water tank 6 , and the bottom of the inner cavity of the piston cylinder 41 is connected to the bottom of the inner cavity of the water tank 6 through a water pipe 45 .

[0030] The piston rod 42 is composed of a piston plate 421 and a round rod 422. The piston plate 421 is attached to the inner wall of the piston cylinder 41. The one-way water outlet valve 43 is fixedly connected to the top of the piston plate 421. The blocking rod 44 is fixedly connected to the bottom of the piston plate 421. The control valve 46 is located above the water tank 6 and below the piston plate 421.

[0031] The lifting mechanism 2 includes a motor 21, which is fixedly connected to the top of the portable mobile frame 1 through a support plate. The output shaft of the motor 21 is fixedly sleeved with a threaded rod 22, and the surface of the threaded rod 22 is meshed with a lifting plate 25. The top of the middle part of the lifting plate 25 is fixedly connected with a fixing plate 24, and the top of the fixing plate 24 is fixedly connected with a motor 23. The output shaft of the motor 23 is fixedly sleeved with a spiral protective tube 26, and the inner cavity of the spiral protective tube 26 is fixedly connected with a geophysical metal rod 27. The bottom end of the portable mobile frame 1 is fixedly connected with a guide rod 28, and the lifting plate 25 is movably sleeved on the surface of the guide rod 28.

[0032] The bottom ends of the guide rod 28 and the threaded rod 22 are both movably connected with a circular plate, the spray ring 53 is fixedly connected to the circular plate, the outer surface of the top of the spiral protection tube 26 is fixedly connected with a circular ring 261, and the spiral protection tube 26 is movably sleeved at the center of the lifting plate 25 through the circular ring 261.

[0033] The support ring 34 is fixedly connected to one side of the lifting plate 25 close to the judgment rod 32, and the piston rod 42 is fixedly connected to the top of the lifting plate 25 close to the blocking rod 44; The working principle and beneficial effects of the above technical solution are as follows: when used for the first time, the control valve 46 is opened so that the space below the piston plate 421 in the inner cavity of the piston cylinder 41 is connected to the outside through the control valve 46, and then water is added to the inner cavity of the water storage tank 6 and filled. At this time, water will pass through the water pipe 45 and the one-way water inlet valve 48 through water pressure to enter the space below the piston plate 421 in the inner cavity of the piston cylinder 41, and because the space below the piston plate 421 in the inner cavity of the piston cylinder 41 is connected to the outside through the control valve 46, when water enters the space below the piston plate 421 in the inner cavity of the piston cylinder 41, excess air is discharged from the control valve 46. When the inner cavity of the water storage tank 6 is filled, the water level lines of the water storage tank 6 and the inner cavity of the piston cylinder 41 are equal, and because the control valve 46 is located above the water storage tank 6, water will not be discharged from the control valve 46, and then the control valve 46 is closed; Then, after the portable mobile rack 1 is moved to the designated position, the motor 1 21 is started to drive the threaded rod 22 to rotate. Through the meshing of the threaded rod 22 and the lifting plate 25, the threaded rod 22 rotates and drives the lifting plate 25 meshed therewith to move downward along the surface of the threaded rod 22 and the guide rod 28. When the lifting plate 25 descends, it drives the support ring 34, the piston rod 42, and the spiral protective cylinder 26 to descend. The support ring 34 descends along the surface of the pointed rod 322 and separates from the top circular plate 321. At this time, the spring assembly 31 in the contracted state releases its elasticity after losing the limit of the support ring 34, generating a large pressure to drive the judgment rod 32 to descend. At this time, the bottom of the pointed rod 322 contacts the ground. If the ground is soft soil, the judgment rod 32 continues to descend and inserts the bottom cone into the ground, and drives the L-shaped frame 35 fixedly connected to the top circular plate 321 to move downward to a greater extent, and then drives the lifting double-headed rod 36 to descend to a greater extent in the inner cavity of the judgment cylinder 33 through the L-shaped frame 35, so that the blocking block on the top of the lifting double-headed rod 36 is located at the connection between the cooling pipe 37 and the judgment cylinder 33 to continue to block the judgment cylinder 33 and the cooling pipe 37. At this time, the piston rod 42 descends in the inner cavity of the piston cylinder 41 to squeeze the water below the inner cavity of the piston cylinder 41, and because the cooling pipe 37 and the judgment cylinder 33 are blocked, the one-way water inlet valve 48 is a one-way water inlet, so that the water cannot be discharged from the cooling pipe 37 and the water pipe 45, and can only pass through the one-way water outlet valve 43 into the upper part of the inner cavity of the piston cylinder 41 for temporary storage; If the ground is a relatively dry hard ground, the judgment rod 32 is blocked above the ground, so that the judgment rod 32 descends by a small amplitude, and the judgment rod 32 drives the L-shaped frame 35 to descend by a small amplitude, and then drives the lifting double-headed rod 36 to descend by a small amplitude in the inner cavity of the judgment tube 33 through the L-shaped frame 35, so that the connecting rod in the middle of the lifting double-headed rod 36 is located at the connection between the cooling pipe 37 and the judgment tube 33, so that the judgment tube 33, the cooling pipe 37, and the water outlet pipe 51 are connected, and at this time, the piston rod 42 descends in the inner cavity of the piston tube 41, and the piston rod 42 descends to squeeze the water below the inner cavity of the piston tube 41 from the cooling pipe 37 and enter the spray ring through the judgment tube 33 along the water outlet pipe 51. The inner cavity of the piston cylinder 41 is sprayed with the inner cavity of the piston cylinder 41 through the nozzle 54, and then sprayed to the spiral protective cylinder 26 to cool the geophysical metal rod 27. The one-way air intake valve 47 is used to allow one-way air intake to the inner cavity of the piston cylinder 41, so that the piston rod 42 can draw air from the one-way air intake valve 47 when the inner cavity of the piston cylinder 41 descends, thereby realizing the judgment of whether the ground is soft and whether the descent of the spiral protective cylinder 26 is smooth by judging the descending amplitude of the rod 32. If it is a harder ground, the geophysical metal rod 27 is sprayed to cool it down, so that the drilling of the spiral protective cylinder 26 is smoother, avoiding the generation of large friction between the soil and the geophysical metal rod 27, which causes the geophysical metal rod 27 to be overheated and damaged; The lifting plate 25 descends and drives the motor 23 to descend, and then the motor 23 operates to drive the spiral protection tube 26 to rotate and descend to drill into the ground; When the lifting plate 25 is halfway down, the piston rod 42 is driven to halfway down in the inner cavity of the piston cylinder 41. At this time, the blocking rod 44 is inserted into the upper part of the inner cavity of the cooling tube 37 to block the cooling tube 37. If the ground is a relatively dry hard ground, at this time, half of the water in the inner cavity of the piston cylinder 41 has been sprayed from the nozzle 54 to the ground at the spiral protection cylinder 26, and the other half is squeezed by the piston rod 42 and temporarily stored in the upper part of the inner cavity of the piston cylinder 41 from the one-way water outlet valve 1 43; If the ground is a relatively dry hard ground, when the lifting plate 25 is about to descend to the bottom, the support ring 34 descends along the surface of the pointed plug rod 322 and contacts the top of the bottom circular plate 323. When the lifting plate 25 descends to the bottom, the bottom circular plate 323 is pressed downward to insert the judgment rod 32 into the ground, thereby driving the L-shaped frame 35 on the top of the judgment rod 32 to descend, so that the blocking block on the top of the lifting double-headed rod 36 is located at the connection between the judgment tube 33 and the cooling tube 37 to block the connection between the judgment tube 33 and the cooling tube 37. At this time, the spiral protective tube 26 and the geophysical metal rod 27 are completely located under the ground, and the geophysical metal rod 27 is protected by the spiral protective tube 26, so that hard objects such as stones can be pushed away to prevent the hard objects such as stones from directly contacting the surface of the geophysical metal rod 27, and to prevent the surface of the geophysical metal rod 27 from being subjected to a large friction force from the hard objects such as stones, resulting in scratches or damage due to compression deformation; Then the geophysical metal rod 27 contacts the soil through the rectangular groove of the spiral protective tube 26 to collect geological exploration data.

[0034] Embodiment 2: Figures 1 to 6 As shown, the embodiment of the present invention provides a portable coalfield geological geophysical exploration data acquisition device, the water outlet mechanism 5 includes a water outlet pipe 51, the water outlet pipe 51 is fixedly connected to the top of the piston cylinder 41 and is connected to the inner cavity of the piston cylinder 41, the top of the water outlet pipe 51 is fixedly connected to a one-way water outlet valve 2 52, the bottom end of the one-way water outlet valve 2 52 is fixedly connected to a spray ring 53, the inner side of the spray ring 53 is fixedly connected to a nozzle 54, and the cooling pipe 37 is fixedly connected to the water outlet pipe 51; The working principle and beneficial effects of the above technical solution are as follows: when the geophysical metal rod 27 has finished working, the motor 1 21 is started to drive the threaded rod 22 to rotate in the opposite direction, and the motor 23 drives the spiral protective tube 26 to rotate in the opposite direction, so that the lifting plate 25 and the spiral protective tube 26 rise; When the lifting plate 25 rises, it drives the support ring 34 to rise. However, due to the high pressure of the spring assembly 31, the judgment rod 32 cannot rise, and the top of the lifting double-headed rod 36 continues to block the connection between the judgment tube 33 and the cooling tube 37. When the lifting plate 25 rises, it also drives the piston rod 42 to rise in the inner cavity of the piston cylinder 41, and the piston rod 42 squeezes the water above the inner cavity of the piston cylinder 41, so that the water flows along the water outlet pipe 51 through the one-way water outlet valve 2 52 into the inner cavity of the spray ring 53. At this time, due to the blockage of the lifting double-headed rod 36, the water cannot enter the cooling pipe 37 from the judgment cylinder 33; The water entering the inner cavity of the spray ring 53 is sprayed from the nozzle 54 at high pressure to the surface of the spiral protective tube 26 and the geophysical metal rod 27, so that when the spiral protective tube 26 and the geophysical metal rod 27 rise from the ground, the surface of the spiral protective tube 26 and the geophysical metal rod 27 can be sprayed and cleaned, thereby washing away the soil on the surface of the geophysical metal rod 27, so that the geophysical metal rod 27 remains clean and convenient after leaving the soil, and also avoids soil remaining in the inner cavity of the spiral protective tube 26; Since the top of the lifting double-headed rod 36 blocks the cooling tube 37, the space below the piston plate 421 in the inner cavity of the piston cylinder 41 is in a sealed state. At this time, as the piston rod 42 rises in the inner cavity of the piston cylinder 41, suction is generated, so that the water in the inner cavity of the water storage tank 6 enters the space below the piston plate 421 in the inner cavity of the piston cylinder 41 through the water pipe 45 and the one-way water inlet valve 48, and fills the space below the piston plate 421 in the inner cavity of the piston cylinder 41. As the lifting plate 25 rises, the support ring 34 is driven to rise along the surface of the pointed insertion rod 322. When the lifting plate 25 rises to the top, the support ring 34 pushes the top circular plate 321 upward and drives the spring assembly 31 to contract. The top circular plate 321 then rises and drives the judgment rod 32 to rise and reset. When the judgment rod 32 rises and resets, it drives the L-shaped frame 35 to rise. The L-shaped frame 35 drives the lifting double-headed rod 36 to rise in the inner cavity of the judgment tube 33, and makes the blocking block at the bottom of the lifting double-headed rod 36 located at the connection between the judgment tube 33 and the cooling tube 37, thereby blocking the cooling tube 37.

[0035] Working principle and use process: before use, pull out the plug 7 from the top of the water tank 6, then add water to the inner cavity of the water tank 6, and start the control valve 46 at the same time, so that the inner cavity of the piston cylinder 41 is connected with the external air. At this time, the water in the inner cavity of the water tank 6 enters the space below the piston plate 421 in the inner cavity of the piston cylinder 41 along the water pipe 45 and the one-way water inlet valve 48 through the water pressure, and because the control valve 46 is located above the water tank 6, after the inner cavity of the water tank 6 is filled with water, the water level in the inner cavity of the water tank 6 is the same as the water level below the inner cavity of the piston cylinder 41 and is located below the control valve 46, and then the control valve 46 is closed; When it is needed, after the portable mobile frame 1 is moved to the designated position, the motor 1 21 is started to drive the threaded rod 22 to rotate. When the threaded rod 22 rotates, the lifting plate 25 engaged therewith is driven to descend along the axis direction of the threaded rod 22 and the guide rod 28, and the motor 2 23 is operated to drive the spiral protection cylinder 26 to rotate; When the lifting plate 25 descends, it drives the rotating spiral protection cylinder 26 to descend and drill into the ground, drives the piston rod 42 to descend in the inner cavity of the piston cylinder 41, and drives the support ring 34 to descend; The support ring 34 descends along the surface of the pointed insertion rod 322 and separates from the top circular plate 321. At this time, the spring assembly 31 releases its elasticity, generating a large pressure to drive the judgment rod 32 to descend. At this time, the bottom of the pointed insertion rod 322 will contact the ground. If the ground is soft soil, the judgment rod 32 continues to descend and inserts into the ground, and drives the L-shaped frame 35 to move downward by a large amplitude, thereby driving the lifting double-headed rod 36 to descend in the inner cavity of the judgment cylinder 33 by the L-shaped frame 35. The top of the lifting double-headed rod 36 is located at the connection between the cooling tube 37 and the judgment cylinder 33, and the judgment cylinder 33 and the cooling tube 37 continue to be blocked. At this time, the piston rod 42 descends in the inner cavity of the piston cylinder 41, squeezing the water below the inner cavity of the piston cylinder 41, and because the cooling tube 37 and the judgment cylinder 33 are blocked, the water cannot be discharged from the cooling tube 37, and can only pass through the one-way water outlet valve 1 43 into the upper part of the inner cavity of the piston cylinder 41; If the ground is a relatively dry hard ground, the judgment rod 32 is blocked above the ground, so that the judgment rod 32 descends to a smaller extent, thereby driving the lifting double-headed rod 36 to descend to a smaller extent in the inner cavity of the judgment tube 33 through the L-shaped frame 35, so that the middle part of the lifting double-headed rod 36 is located at the connection between the cooling tube 37 and the judgment tube 33, so that the judgment tube 33, the cooling tube 37, and the water outlet pipe 51 are connected. At this time, the piston rod 42 descends in the inner cavity of the piston tube 41, and the external air is sucked into the upper part of the inner cavity of the piston tube 41 through the one-way air inlet valve 47. Then, the piston rod 42 descends to squeeze the water below the inner cavity of the piston tube 41 from the cooling tube 37 and enter the inner cavity of the spray ring 53 through the judgment tube 33 along the water outlet pipe 51, and then sprays to the spiral protection tube 26 through the nozzle 54 to cool the geophysical metal rod 27; When the piston rod 42 is halfway down in the inner cavity of the piston cylinder 41, it drives the blocking rod 44 to insert into the inner cavity of the cooling tube 37 to block the cooling tube 37, so that the remaining half of the water in the inner cavity of the piston cylinder 41 cannot enter and be discharged from the cooling tube 37, and can only enter the upper part of the inner cavity of the piston cylinder 41 from the one-way water outlet valve 1 43; When the spiral protection cylinder 26 is about to be completely inserted into the ground, the support ring 34 contacts the top of the bottom circular plate 323 along the surface of the pointed insertion rod 322. When the spiral protection cylinder 26 is completely inserted into the ground, the bottom circular plate 323 is driven to move downward, so that the judgment rod 32 is also inserted into the ground, and the top of the lifting double-headed rod 36 is driven by the L-shaped frame 35 to be located at the connection between the judgment cylinder 33 and the cooling pipe 37, thereby blocking the judgment cylinder 33 and the cooling pipe 37. Then the geophysical metal rod 27 works. After the work is completed, the motor 1 21 is started to drive the threaded rod 22 to rotate in the opposite direction, thereby driving the lifting plate 25 to move upward, driving the support ring 34 to rise and separate from the top of the bottom circular plate 323. However, due to the pressure of the spring assembly 31, the judgment rod 32 cannot leave the soil. When the lifting plate 25 moves upward, the spiral protection cylinder 26 and the piston rod 42 are synchronously driven to rise. When the piston rod 42 rises, the water located above the inner cavity of the piston cylinder 41 is squeezed out from the water outlet pipe 51 through the one-way water outlet valve 2 52 to the spray ring 53. At the same time, during the process of the piston rod 42 rising, the water in the inner cavity of the water storage tank 6 is drawn out along the water pipe 45 through the one-way water inlet valve 48 and stored in the space below the piston plate 421 in the inner cavity of the piston cylinder 41 by the water pressure and the suction force when the piston rod 42 rises. The water squeezed into the inner cavity of the spray ring 53 is sprayed at high pressure to the surface of the spiral protection tube 26 and the geophysical metal rod 27 through the nozzle 54, so as to wash the soil on the surface of the spiral protection tube 26 and the geophysical metal rod 27; When the lifting plate 25 moves to the top, it contacts the bottom of the top circular plate 321, pushing the top circular plate 321 upward, thereby driving the judgment rod 32 to move upward, causing the spring assembly 31 to contract. The judgment rod 32 moves upward, driving the L-shaped frame 35 to move upward, thereby driving the bottom of the lifting double-headed rod 36 to be located at the connection between the judgment tube 33 and the cooling tube 37.
