Description

Technical Field

[0001] The present application relates to the technical field of water level survey equipment, and in particular to a groundwater level survey device. Background Art

[0002] Groundwater level surveys are usually conducted by drilling water level observation wells and using groundwater level survey equipment to measure groundwater levels. Groundwater level survey equipment can help relevant departments and institutions understand the changing trend of groundwater levels and the supply and demand of groundwater resources, so as to manage and utilize them reasonably.

[0003] For example, a groundwater level survey device with patent number (CN202022200431.6) includes a main board, characterized in that: slide grooves are provided on both sides of the main board, and L-shaped sliding plates are slidably connected in the two slide grooves, and one side of the two L-shaped sliding plates is fixedly connected to an L-shaped fixed plate, and the bottoms of the two L-shaped fixed plates are fixedly connected to two supporting legs, and the tops of both sides of the main board are movably connected to L-shaped fixing blocks through pins, and the inner sides of the two L-shaped fixing blocks are respectively overlapped with the outer sides of the two L-shaped fixing plates, and a battery is arranged on one side of the top of the main board. A warning light is provided on the other side of the top of the mainboard, and a through hole is opened in the middle position of the top of the mainboard, and vertical plates are fixedly connected on both sides of the through hole, and a motor is fixedly connected to the outer side of one of the vertical plates, and bearings are fixedly connected on the opposite sides of the two vertical plates, and rotating shafts are movably inserted in the two bearings, and the opposite ends of the two rotating shafts are fixedly connected to the same rotating rod, and one end of one of the rotating shafts passes through the bearing and is fixedly connected to the output shaft of the motor, a cable is fixedly wound on the rotating rod, and one end of the cable passes through the through hole and is fixedly connected to a conical column, and a pressure sensor is fixedly connected to the bottom of the conical column.

[0004] In the above structure, the cable is released by rotating the rotating rod. When the pressure sensor at the bottom of the conical column reaches the water surface, the cable release is stopped to measure the groundwater level. Since the cable is wound around the rotating rod, the cable may bend to a certain extent when released, resulting in inaccurate measurement results. The cable needs to be squeezed against the straightening piece during straightening, and the thrust generated by the rotating rod in releasing the cable is far from enough.

[0005] Therefore, it is necessary to design a groundwater level survey device that can pull out and straighten the cable. Utility Model Content

[0069] The groundwater level survey device further includes: a straightening component 3, a pulling component 202;

[0070] The pulling assembly 202 is arranged below the straightening assembly 3 in the pulling box 2. Since the cable 402 needs to be squeezed with the straightening assembly 3 during the straightening process, the thrust generated by the rotation of the rotating shaft 401 to release the cable 402 is far from enough to drive the cable 402 to straighten.

The piston rod of the second cylinder 215 is fixedly connected to an end of the first clamp 204 away from the cable 402 to drive the first clamp 204 to move; the first cylinder 206 and the second cylinder 215 are both electrically connected to the pressure sensor 406.

[0074] The setting of the contact surface 210 can drive the second clamp 205 to rotate while moving the first clamp 204, thereby clamping the cable 402; the setting of the anti-wear wheel 212 can reduce the friction between the contact surface 210 and the second clamp 205 when the contact surface 210 and the second clamp 205 are in conflict, thereby reducing the wear of parts; since the first cylinder 206 and the second cylinder 215 are set, the second cylinder 215 drives the first clamp 204 and the second clamp 205 to clamp the cable 402, and after clamping the cable 402, the first cylinder 206 can drive the clamp seat 203 to move downward to pull out the cable 402 in the straightening component 3, and after pulling out the cable 402, the second cylinder 215 drives the first clamp 204 to release the clamping, and after the first clamp 204 and the second clamp 205 are released and clamped, the first cylinder 206 extends upward; this can be repeated to continuously pull the cable 402 out of the straightening component 3.

[0075] The straightening assembly 3 is disposed in the pulling box 2 to straighten the cable 402 released from the rotating shaft 401 to avoid measurement errors caused by bending of the cable 402;

[0076] Specifically, the straightening assembly 3 includes: a first straightening seat 301, a second straightening seat 302, and a plurality of straightening wheels 303; the first straightening seat 301 is fixed in a U-shape in the pulling box 2, the second straightening seat 302 is of the same shape as the first straightening seat 301 and is arranged opposite to each other, the side surface portion of the first straightening seat 301 opposite to the second straightening seat 302 is concave to form a moving groove 304, and a moving plate 305 is fixed on the surface of the second straightening seat 302 opposite to the first straightening seat 301, and the moving plate 305 is movably arranged in the moving groove 304 and fits with the inner wall of the moving groove 304; a third cylinder 306 is fixedly installed in the pulling box 2, and the piston rod of the third cylinder 306 is fixedly connected to the second straightening seat 302 to drive the second straightening seat 302 to move in a direction close to or away from the first straightening seat 301; the third cylinder 306 is electrically connected to the pressure sensor 406;

[0077] More specifically, a plurality of straightening wheels 303 are rotatably arranged inside the first straightening seat 301 and the second straightening seat 302, and a portion of the circumferential side wall of the straightening wheel 303 is concave to form an extrusion groove 307; when the second straightening seat 302 moves toward the first straightening seat 301, the circumferential side wall of the cable 402 can fit with a portion of the inner wall of the extrusion groove 307 on the straightening wheel 303, and when the cable 402 is pulled downward, the cable 402 can be straightened to a straight state by the extrusion groove 307; the straightening wheels 303 in the first straightening seat 301 and the straightening wheels 303 in the second straightening seat 302 are alternately arranged along the height direction of the pulling box 2.

[0078] When measurement is required, the third cylinder 306 drives the second straightening seat 302 to move towards the first straightening seat 301, and the straightening wheel 303 can clamp the cable 402 in the extrusion groove 307 of the straightening wheel 303. When the cable 402 is pulled downward, the cable 402 drives the straightening wheel 303 to rotate and straighten the cable 402 to a straight state; since the second straightening seat 302 is movably arranged on the first straightening seat 301, when the measurement is completed and the cable 402 is retracted upward, the second straightening seat 302 can be moved to release the extrusion of the straightening wheel 303 on the cable 402, thereby avoiding repeated straightening during the retraction of the cable 402.

[0079] The specific working process is as follows:

[0080] 1. Start the device, the third cylinder 306 starts the straightening wheel 303 to clamp the cable 402, and at the same time the second cylinder 215 drives the first clamp 204 and the second clamp 205 to clamp the cable 402. After clamping the cable 402, the first cylinder 206 retracts downward to pull the cable 402 downward;

[0081] 2. When the first cylinder 206 is retracted to the bottom, the piston rod of the second cylinder 215 is retracted, driving the first clamp 204 and the second clamp 205 to release the clamped cable 402; after releasing the clamp, the first cylinder 206 extends upward, pushing the clamp seat 203 to move upward; repeating this process, the cable 402 is continuously pulled out and straightened;

[0082] 3. When the pressure sensor 406 reaches the water surface, the telescopic rod of the second cylinder 215 is retracted to release the clamping, and the first cylinder 206 is reset; the telescopic rod of the third cylinder 306 is retracted to release the straightening;

[0083] 4. Record the measurement data and rotate the crank 404 to retract the cable 402.
