[0003] The document with the publication number CN117665235A discloses a groundwater monitoring device, including a detection and winding device and a sampling mechanism. A ranging rope is wound around the detection and winding device, and the other end of the ranging rope is connected to the sampling mechanism. The sampling mechanism includes a connecting piece. The top of the connecting piece is fixedly connected to the end of the ranging rope. The bottom of the connecting piece is connected to a working box. Several fixing plates are arranged at the bottom side of the working box. Several rollers are arranged on the outer surface of the fixing plate. An internal toothed ring is fixed at the bottom of the fixing plate. The invention has the following beneficial effects. Through the design of the protection and cleaning component, during the descent and ascent of the device, the descent action of the sampling bin and the rotational self-rotation action of the cleaning plate will be carried out through the protection and cleaning component.

[0026] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0027] 1. In the present invention, by providing an auxiliary drive assembly, the second motor drives the connecting rod to rotate through the drive gear, transmission gear, drive lead screw, lead screw seat and connecting rod, so that the drive wheel fits with the inside of the shaft. When the first motor is started, the first motor drives the main housing to rise or fall in the shaft through the drive shaft, driving wheel, transmission belt, driven wheel, second rotating shaft and drive wheel, reducing the load of the traction cable, avoiding the fracture of the traction cable, improving the lowering and recovery efficiency of the device in the shaft, and even if the traction cable breaks midway, the device can still be recovered through the operation of the drive wheel, reducing losses.

[0028] 2. In the present invention, by providing a filtering and cleaning assembly, the third motor drives multiple reciprocating lead screws to rotate around the protective filter basket through the connecting shaft, rotating disc, connecting plate and rotating ring. At this time, the linkage gear rotates automatically under the drive of the fixed gear ring, and the linkage gear drives the same lifting ring to move reciprocally in the vertical direction through the reciprocating lead screw. At the same time, the lifting ring makes a circular motion under the drive of the reciprocating lead screw. The brush plate inside the lifting ring cleans the attachments on the protective filter basket, reducing the accumulation of impurities that affect the water quality and thus the monitoring results of the monitoring main body. At the same time, the rotation of the lifting ring itself drives the blade to rotate, and the blade can cut and remove the flexible impurities underwater, avoiding the entanglement of the flexible impurities on the surface of the protective filter basket or the accumulation of the flexible impurities, ensuring the smooth flow of groundwater, and improving the accuracy of the water quality and water level monitoring data.

[0029] 3. In the present invention, by providing an alignment assembly, when the connecting rod rotates around the fourth rotating shaft, the fourth bevel gear rotates automatically under the drive of the third bevel gear. The fourth bevel gear drives the drive box to deflect through the linkage shaft, second bevel gear, first bevel gear and first rotating shaft, and the deflection direction is opposite to the rotation direction of the connecting rod, so that the top of the drive box is always flush with the horizontal plane, ensuring the vertical fit of the drive wheel with the inner wall of the shaft, improving the stability of the movement of the main housing and the monitoring main body, and at the same time ensuring the vertical orientation of the drill bit, avoiding the deviation of the drill bit obstacle clearance direction, and improving the obstacle clearance ability of the drill bit.

Driving wheels 303 for traveling are symmetrically arranged on the outer surface of the second rotating shaft. The connecting rod 301 adjusts the angle according to the width of the shaft and makes the driving wheels 303 fit against the inner wall of the shaft. The driving wheels 303 drive and drive the main housing 5 to move in the shaft. Four groups of mounting seats 309 are connected to the four surrounding walls of the inner wall of the main housing 5. The two mounting seats 309 in the same group are symmetrically arranged on the same vertical line. Two rotatable driving lead screws 307 are symmetrically arranged between the two groups of mounting seats 309. The two driving lead screws 307 are fixedly connected to each other, and the thread directions of the two driving lead screws 307 are opposite. A lead screw seat 308 is threadedly connected to the outer surface of the driving lead screw 307. Sliding grooves are formed on the outer walls of the four surrounding walls of the main housing 5. One end of the lead screw seat 308 extends outside the sliding groove and is slidably connected to the sliding groove. One end of the lead screw seat 308 is hinged to a connecting rod 306. The end of the connecting rod 306 away from the lead screw seat 308 is hinged to the bottom of the connecting rod 301. The end of the connecting rod 301 away from the drive box 304 is hinged to the outer wall of the main housing 5 through a fourth rotating shaft. A first motor 305 is fixedly installed on the outside of the drive box 304 through a mounting plate. One end of the output shaft of the first motor 305 is connected to a drive shaft 318.

An opening is formed on one side of the drive box 304. The transmission belt 315 passes through the opening. Two sixth bevel gears 317 are connected to the outer surface of the drive shaft 318. A fifth bevel gear 316 is meshed with one side of the sixth bevel gear 317. A third rotating shaft is connected to one side of the fifth bevel gear 316. The third rotating shaft extends outside the drive box 304 and is rotationally connected to the drive box 304. The other end of the third rotating shaft is connected to one side of the drill bit 302. An installation frame 312 is connected inside the main housing 5. A second motor 311 is fixedly installed at the bottom of the installation frame 312. One end of the output shaft of the second motor 311 is connected to a driving gear 310. One end of the driving lead screw 307 located below extends to the other side of the mounting seat 309 and is connected to a transmission gear 313. The driving gear 310 is meshed with the transmission gear 313. Both the first motor 305 and the second motor 311 are waterproof motors.

[0045] The implementation method is specifically as follows: By setting the auxiliary driving component 3, the second motor 311 drives the connecting rod 306 to drive the connecting rod 301 to rotate through the driving gear 310, the transmission gear 313, the driving lead screw 307, the lead screw seat 308 and the connecting rod 306, so that the driving wheel 303 fits with the inside of the shaft. The first motor 305 is started. The first motor 305 drives the main housing 5 to rise or fall in the shaft through the driving shaft 318, the driving wheel 314, the transmission belt 315, the driven wheel 319, the second rotating shaft and the driving wheel 303, reducing the load of the traction cable 1, avoiding the breakage of the traction cable 1, improving the lowering and recovery efficiency of the device in the shaft, and even if the traction cable 1 breaks midway, the device can still complete the recovery through the operation of the driving wheel 303, reducing losses. At the same time, the driving shaft 318 drives the drill bit 302 to rotate through the sixth bevel gear 317 and the fifth bevel gear 316. During recovery, if the shaft is accidentally blocked by sundries, the self-rotation of the drill bit 302 can achieve automatic obstacle clearance.

[0046] The steering component 2 includes a linkage shaft 203. The two ends of the linkage shaft 203 are respectively connected with a second bevel gear 202 and a fourth bevel gear 206. One end of the first rotating shaft is connected with a first bevel gear 201. The first bevel gear 201 is meshed and connected with the second bevel gear 202. One end of the fourth rotating shaft is connected with a third bevel gear 205. One side of the third bevel gear 205 is meshed and connected with the fourth bevel gear 206. Two mounting parts 204 are connected to one side of the connecting rod 301. The linkage shaft 203 is rotatably connected in the mounting parts 204.

[0047] The implementation method is specifically as follows: By setting the steering component 2, when the connecting rod 301 rotates around the fourth rotating shaft, the fourth bevel gear 206 rotates self-driven by the third bevel gear 205. The fourth bevel gear 206 drives the drive box 304 to deflect through the linkage shaft 203, the second bevel gear 202, the first bevel gear 201 and the first rotating shaft, and the deflection direction is opposite to the rotation direction of the connecting rod 301, so that the top of the drive box 304 is always flush with the horizontal plane, ensuring the vertical fit of the driving wheel 303 with the inner wall of the shaft, improving the stability of the main housing 5 and the monitoring body 9 during movement, and at the same time ensuring the vertical orientation of the drill bit 302, avoiding the deviation of the obstacle clearance direction of the drill bit 302.

[0048] The filtering and cleaning component 4 includes a protective filter basket 401. The protective filter basket 401 is connected to the bottom of the main housing 5. The monitoring body 9 is arranged inside the protective filter basket 401. The bottom of the protective filter basket 401 is connected with a waterproof box 402. The bottom of the waterproof box 402 is rotatably connected with a connecting shaft. The bottom of the connecting shaft is connected with a rotating disk 404. A plurality of connecting plates 403 are connected to the outer peripheral side of the rotating disk 404. The top of the connecting plate 403 is rotatably connected with a reciprocating lead screw 405. The outer peripheral side of the protective filter basket 401 is rotatably connected with a rotating ring 412. A plurality of sleeve 413 are connected to the outer peripheral side of the rotating ring 412. One end of the reciprocating lead screw 405 away from the connecting plate 403 is rotatably connected with the sleeve 413. The outer surfaces of a plurality of reciprocating lead screws 405 are threadedly connected with the same lifting ring 409. A plurality of blades 407 are connected to the outer peripheral side of the lifting ring 409. A plurality of brush plates 410 are connected to the inner peripheral side of the lifting ring 409. The brush plates 410 are in contact with the protective filter basket 401. One end of the reciprocating lead screw 405 away from the connecting plate 403 extends to the other side of the sleeve 413 and is connected with a linkage gear 406. A fixed toothed ring 408 is connected to the outer surface of the protective filter basket 401. The linkage gear 406 is meshed with the fixed toothed ring 408. A third motor 411 is connected inside the waterproof box 402. One end of the connecting shaft extends into the waterproof box 402 and is connected with one end of the output shaft of the third motor 411.

[0049] The specific implementation method is as follows: By setting the filtering and cleaning component 4, the third motor 411 drives a plurality of reciprocating lead screws 405 to rotate around the circumference of the protective filter basket 401 through the connecting shaft, the rotating disk 404, the connecting plate 403 and the rotating ring 412. At this time, the linkage gear 406 rotates by itself under the drive of the fixed toothed ring 408. The linkage gear 406 drives the same lifting ring 409 to make a reciprocating motion in the vertical direction through the reciprocating lead screw 405. At the same time, the lifting ring 409 makes a circular motion under the drive of the reciprocating lead screw 405. The brush plates 410 inside the lifting ring 409 clean the substances attached to the protective filter basket 401, reducing the accumulation of impurities and affecting the water quality, thereby affecting the monitoring results of the monitoring body 9. At the same time, the rotation of the lifting ring 409 itself drives the blades 407 to rotate. The blades 407 can cut and remove the flexible impurities underwater, avoiding the flexible impurities from winding around the surface of the protective filter basket 401 or the accumulation of flexible impurities.

[0050] Working principle: When in use, the staff first digs through the shaft connected to the groundwater canal. Then, the staff lowers the main housing 5 and the monitoring body 9 into the groundwater canal through the shaft by the traction cable 1. The floating airbag 6 drives the main housing 5 to float on the water surface of the groundwater canal. The staff controls the amount of air delivered by the air pump 8 to the floating airbag 6 to change the descending depth of the floating airbag 6 on the main housing 5, thereby changing the monitoring depth of the monitoring body 9.

[0051] During the monitoring process, the third motor 411 drives the connecting shaft to rotate, the connecting shaft drives the rotating disk 404 to rotate, the rotating disk 404 drives the connecting plate 403 to rotate, and the connecting plate 403 cooperates with the rotating ring 412 to drive a plurality of reciprocating lead screws 405 to rotate circumferentially around the protective filter basket 401. At this time, the linkage gear 406 revolves around the fixed gear ring 408, causing the linkage gear 406 to rotate on its own axis. The linkage gear 406 drives the reciprocating lead screws 405 to rotate, and the plurality of reciprocating lead screws 405 drive the same lifting ring 409 to perform a reciprocating motion in the vertical direction. At the same time, the lifting ring 409 performs a circumferential motion driven by the reciprocating lead screws 405, and the brush plate 410 inside the lifting ring 409 cleans the attachment on the protective filter basket 401.

[0052] During the lowering or recovery process of the entire device, the staff adjusts the position of the connecting rod 301 according to the actual width of the shaft. During this process, the second motor 311 drives the driving gear 310 to rotate, the driving gear 310 drives a plurality of transmission gears 313 to rotate, the transmission gears 313 drive two driving lead screws 307 to rotate, the two driving lead screws 307 drive two lead screw seats 308 to move relatively, the lead screw seats 308 drive the connecting rod 306 to move, the connecting rod 306 drives the connecting rod 301 to rotate, and makes the driving wheel 303 fit with the inside of the shaft. During this process, the alignment component 2 operates. When the connecting rod 301 rotates around the fourth rotating shaft, the fourth bevel gear 206 rotates relative to the third bevel gear 205, causing the fourth bevel gear 206 to rotate on its own axis. The fourth bevel gear 206 drives the linkage shaft 203 to rotate, the linkage shaft 203 drives the second bevel gear 202 to rotate, the second bevel gear 202 drives the first bevel gear 201 to rotate, and the first bevel gear 201 drives the drive box 304 to deflect through the first rotating shaft, and the deflection direction is opposite to the rotation direction of the connecting rod 301, so that the top of the drive box 304 is always flush with the horizontal plane.

[0053] After the position of the driving wheel 303 is adjusted, the first motor 305 is started. The first motor 305 drives the drive shaft 318 to rotate, the drive shaft 318 drives the driving wheel 314 to rotate, the driving wheel 314 drives the driven wheel 319 to rotate through the transmission belt 315, the driven wheel 319 drives the second rotating shaft to rotate, the second rotating shaft drives the driving wheel 303 to rotate, and the driving wheel 303 drives the main housing 5 to rise or fall in the shaft. At the same time, the drive shaft 318 drives the sixth bevel gear 317 to rotate, the sixth bevel gear 317 drives the fifth bevel gear 316 to rotate, and the fifth bevel gear 316 drives the drill bit 302 to rotate for obstacle clearance.

[0054] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
