Description

Technical Field

[0001] The present invention belongs to the field of deep groundwater exploration and detection devices, and particularly relates to a deep groundwater exploration and detection device. Background Art

[0002] Hydrogeology is a branch discipline of geology. Hydrogeology mainly studies the physical properties and chemical compositions of groundwater, as well as the exploration and rational utilization of groundwater resources. When exploring groundwater resources, a groundwater detector is needed to detect groundwater resources.

[0003] Most of the existing groundwater level detectors are equipped with a detection head, which is generally placed in groundwater. Impurities and viscous objects in the groundwater will adhere to the outer wall of the detection head. Therefore, it is necessary to intermittently take out and manually clean the adhesions, which is a relatively troublesome process, and the detection results will be inaccurate during the lifting and lowering process.

[0004] Therefore, there is an urgent need for a deep groundwater exploration and detection device that can deploy the detector to detect the surrounding groundwater quality after reaching the detection depth. Summary of the Invention

[0005] The purpose of the present invention is to address the above problems existing in the prior art and propose a deep groundwater exploration and detection device that can deploy the detector to detect the surrounding groundwater quality after reaching the detection depth.

[0006] To achieve the above purpose, the present invention adopts the following technical solutions: A deep groundwater exploration and detection device includes a machine body. A second sliding rod is slidably arranged in the middle of the machine body. One end of the bottom of the second sliding rod is fixedly provided with a rotating head. On both sides of the second sliding rod close to the rotating head direction, rolling balls are respectively slidably arranged. The rolling balls are connected to the second sliding rod through fourth springs. A detection box is slidably sleeved on the outer side of the second sliding rod corresponding to the rolling balls. A filter screen is fixedly embedded on the circumferential side wall of the outer side of the detection box. A detector is fixedly arranged inside the detection box. One end of the second sliding rod far from the rotating head is fixedly provided with a water pump. One side of the water pump far from the second sliding rod is fixedly provided with a threaded pipe. A toothed ring is rotatably sleeved on the threaded pipe. The toothed ring is in threaded transmission contact with the threaded pipe. One side of the toothed ring is fixedly provided with a motor. The output end of the motor is fixedly provided with a gear. The gear is in meshing contact with the toothed ring, and can deploy the detector to detect the surrounding groundwater quality after reaching the detection depth.

[0007] Preferably, a plurality of first sliding rods are respectively slidably arranged along the circumferential direction inside the rotating head. One end of the first sliding rod facing the outside is fixedly provided with a blade. The first sliding rod is connected to the rotating head through a second spring.

[0008] Preferably, sliding blocks are respectively arranged on both sides of the water pump. The sliding blocks are connected to the machine body through first springs. A push rod is fixedly arranged at one end of the sliding block away from the water pump. Rotary arms are respectively rotatably arranged on the circumferential surfaces of both sides of the machine body. The rotary arms are connected to the machine body through torsion springs. A stop rod is fixedly arranged at the corresponding position of the rotary arm and the push rod.

[0009] Preferably, a balance block is fixedly arranged at one end of the rotary arm away from the stop rod. A first hook is fixedly arranged on the side of the balance block close to the machine body. A second hook is slidably arranged inside the machine body corresponding to the first hook. The second hook is connected to the machine body through a third spring. A thrust bearing is sleeved on the second sliding rod in the direction close to the water pump. When the second sliding rod slides and unfolds and rotates, the blade can extend out to stir and rotate the surrounding groundwater to avoid impurities adhering to the filter screen and causing blockage. At the same time, the rotary arm opens to fix or self-balance the machine body, offsetting part of the torque generated by the blade.

[0010] Preferably, a ratchet is fixedly sleeved on the threaded pipe. The ratchet can only rotate in one direction. A certain force is required when the ratchet rotates in the rotatable direction. The ratchet is in sliding contact with the machine body.

[0011] Preferably, a channel communicating with the water pump is opened in the middle of the rotating head and the second sliding rod. A water suction head is slidably arranged in the middle of the bottom of the rotating head. The water suction head is connected to the internal channel of the rotating head through a hose. An iron block is fixedly arranged on one side of the water suction head. An electromagnet is fixedly arranged at the corresponding position of the internal of the rotating head and the electromagnet.

[0012] Preferably, a fixing rod is fixedly arranged in the middle of the top of the machine body. The side wall of the threaded pipe located inside the fixing rod is a smooth side wall. The threaded pipe is in sealed sliding contact with the fixing rod. Through holes are opened on both sides of the fixing rod and communicate with the inside of the threaded pipe. A tension sensor is fixedly arranged on the side of the fixing rod away from the machine body. A pull rope is fixedly arranged on the side of the tension sensor away from the fixing rod. When the machine body is pulled up from the deep groundwater and encounters an obstacle such as a well wall collapse during the rising process, it can spray water on the obstacle to wash it away so that the machine body can rise normally.

A tension sensor 35 is fixedly provided on the side of the fixed rod 34 away from the body 10. A pull rope 36 is fixedly provided on the side of the tension sensor 35 away from the fixed rod 34. When the body 10 encounters an obstacle such as a well wall collapse during the process of being pulled up from the deep groundwater, it can spray water on the obstacle to wash it away so that the body 10 can rise normally.

[0034] Working principle

[0035] When the deep groundwater exploration and detection device starts from a stationary state, the device is lowered from the ground to the detection depth. During the descent, although the pressure gradually increases, the detector 18 is hermetically wrapped by the body 10 and the rotating head 45. Therefore, the water along the way will not enter the detector 18 and cause deviation of the detection result.

[0036] After reaching the specified depth, the motor 11 starts to drive the gear 12 to rotate. The gear 12 drives the toothed ring 31 to rotate. Since a certain torque is required when the ratchet 33 rotates, the threaded pipe 32 does not rotate at this time. The toothed ring 31 and the threaded pipe 32 rotate relative to each other. The toothed ring 31 drives the threaded pipe 32 to move towards the rotating head 45. The threaded pipe 32 drives the second slide rod 28 to move through the water pump 30. The second slide rod 28 drives the rotating head 45 to move and unfold. The balls 42 on both sides of the second slide rod 28 drive the detection box 20 to move and unfold. The filter screen 19 contacts the groundwater and filters it. The detector 18 detects the groundwater here. At the same time, the water pump 30 is separated from the push block 13. The push block 13 drives the push rod 14 to move towards the inside of the body 10 under the action of the first spring 15. The stop rod 37 loses the limit of the push rod 14. The thrust bearing 29 contacts and pushes the second hook 40 to move. The second hook 40 is separated from the first hook 39. The swing arm 16 rotates and unfolds under the action of the torsion spring 38. If there is solid matter outside the swing arm 16, the swing arm 16 drives the balance block 17 to catch the solid matter to fix the body 10. If there is no solid matter outside the swing arm 16 to fix, the swing arm 16 unfolds to the maximum angle.

[0037] At this time, the ratchet 33 moves to the toothed ring 31 and contacts and fits with it. The toothed ring 31 continues to rotate and drives the ratchet 33 to rotate. The ratchet 33 drives the threaded pipe 32 to rotate. Further, the rotating head 45 rotates. The blades 27 extend outside the rotating head 45 due to centrifugal force. Under the action of the blades 27, the surrounding groundwater begins to stir and rotate, preventing impurities from adhering to the filter screen 19 and causing blockage to affect detection.

[0038] After the detection is completed, the pull rope 36 is pulled to start rising. During the rising process, if there are collapse objects on the upper well wall of the body 10 that hinder the rising of the body 10, the pressure at the tension sensor 35 will increase. The tension sensor 35 controls the electromagnet 24 to cut off the power. The electromagnet 24 loses its magnetic force. The water suction head 22 drops to contact the groundwater as much as possible. The water pump 30 starts to pump the groundwater and spray it out through the through holes on both sides of the fixed rod 34 to wash and dissolve the obstacles at the top of the body 10, ensuring that the body 10 can rise smoothly.
