Description

Technical Field

[0001] This invention belongs to the field of water level monitoring technology, and specifically relates to a hydrological engineering geological water level monitoring device. Background Technology

[0002] In the field of hydrogeology, water level monitoring is a crucial technical tool. It involves long-term water level observations and records at different regions or specific locations, combined with other factors such as rainfall and evaporation, to estimate local groundwater reserves and their sustainable exploitation capacity. For areas that rely on groundwater as their primary water source, timely understanding of groundwater levels helps in developing appropriate measures to ensure drinking water safety. Therefore, regular groundwater level monitoring helps us predict potential risks and implement effective response strategies to minimize losses.

[0003] Chinese patent application CN116007712A discloses a hydrological engineering geological water level monitoring device, including a floating platform, a traction mechanism, and a fixing device. The fixing device is connected to the bottom of the traction mechanism via a traction rope. The traction mechanism can retract and extend the traction rope installed on the top of the fixing device. The monitoring mechanism is installed on one side of the traction mechanism and connected to the traction rope. The monitoring mechanism can measure the angle of the traction rope. By recording the angle value of the traction rope on a fan-shaped scale plate and combining it with the extension length of the traction rope recorded by a displacement sensor, the height value between the floating platform and the bottom of the water is calculated. However, due to the presence of underwater weeds and other debris, after the traction rope sinks to the bottom, the weeds and other debris will become entangled on the traction rope. This not only increases the weight of the rope itself but also affects the force of the water flow on the traction rope, resulting in a large deviation in the measurement results. Furthermore, when retrieving the traction rope, the weeds or debris entangled on the traction rope will affect the retrieval operation. Summary of the Invention

[0004] To address the aforementioned problems, the purpose of this invention is to provide a hydrological engineering geological water level monitoring device that can remove debris such as aquatic plants entangled in ropes, thus preventing them from affecting the final monitoring results.

[0005] The technical solution of this invention is: a hydrological engineering geological water level monitoring device, comprising a floating platform mechanism and a counterweight mechanism connected to the bottom of the floating platform mechanism by a rope, wherein a cleaning mechanism is movably sleeved on the outside of the rope, and the cleaning mechanism includes:

[0006] A first loop tube is movably sleeved on the outside of the rope. A first clamping assembly is provided inside the first loop tube. The first clamping assembly is used to clamp the rope and fix the first loop tube.

[0008] A telescopic assembly is connected and disposed between the first ring tube and the second ring tube, and the telescopic assembly is used to adjust the distance between the first ring tube and the second ring tube;

[0009] A cleaning component is disposed on the second loop tube on the side away from the first loop tube, the cleaning component being used to remove debris from the rope.

[0010] Further, the cleaning component includes:

[0011] A sleeve is disposed on the side of the second ring tube away from the first ring tube, and the sleeve is looped around the outside of the rope.

[0012] Multiple support shafts are arranged circumferentially on the side of the sleeve, and all of the multiple support shafts are arranged close to the second annular tube;

[0013] Multiple cleaning plates, each of which has a pivot pin in the middle, the pivot pin being movably disposed in the corresponding support shaft, and the pivot pin being connected to the support shaft by a torsion spring; one end of the cleaning plate near the sleeve is a cutting edge plate, and the other end is a driven plate, the driven plate being located inside the second annular tube;

[0014] A driving component is disposed inside the second annular tube. The driving component is used to drive the driven plate to reciprocate along the radial direction of the second annular tube, thereby causing the cutting plate to reciprocate to contact the surface of the sleeve, and realizing the shearing and cleaning action.

[0015] A control component, located inside the second annular tube, is used to control the operation of the drive component.

[0016] Furthermore, the driving component includes:

[0017] The bearing has its inner ring fixedly sleeved inside the second ring tube;

[0018] The driven gear is fixedly sleeved on the outer ring edge of the bearing;

[0019] A drive disc is fixedly sleeved on the outer ring edge of the bearing. The edge of the drive disc is provided with multiple actuating elements. The actuating elements are used to intermittently contact the driven plate during rotation, thereby driving the driven plate to reciprocate along the radial direction of the second ring tube.

[0020] A drive motor is disposed inside the second ring tube and electrically connected to the control component. The output shaft of the drive motor is provided with a drive gear, which meshes with the driven gear to drive the drive disc to rotate.

[0021] Further, the first clamping assembly includes:

[0022] The first clamping plate is movably disposed on the inner ring side of the first ring tube, and the surface of the first clamping plate near the rope is provided with protrusions;

[0023] The first electro-hydraulic rod is horizontally fixed inside the first ring tube and electrically connected to the control component. The pressure output end of the first electro-hydraulic rod is fixedly connected to the first clamping plate and is used to push the first clamping plate to squeeze and clamp the rope.

[0024] Furthermore, the second clamping assembly includes:

[0025] The second clamping plate is movably disposed on the inner ring side of the second ring tube, and the surface of the second clamping plate near the rope is provided with protrusions;

[0026] The second electro-hydraulic rod is horizontally fixed inside the second ring tube and electrically connected to the control component. The pressure output end of the second electro-hydraulic rod is fixedly connected to the second clamping plate and is used to push the second clamping plate to squeeze and clamp the rope.

[0027] Furthermore, the telescopic assembly includes multiple electrically operated telescopic rods, each of which is electrically connected to the control component. Each of the electric telescopic rods includes a fixed rod fixedly disposed inside the first annular tube and a push rod movably sleeved in the fixed rod. The distal end of the push rod is fixedly connected to the second annular tube.

[0028] Furthermore, the floating platform mechanism includes:

[0029] Support platform;

[0030] A winding assembly is provided on the support platform. The winding assembly includes a winding drum and a servo motor for driving the winding drum to rotate. The winding drum is used to fix and wind the rope.

[0031] A meter counter is fixedly mounted on the support platform and sleeved on the outside of the rope for measuring the length of the lowered rope.

[0032] A control component is mounted on the support platform. The control component is wirelessly connected to the control unit and is used to send control commands to the control unit. The control component is also connected to the servo motor and the meter counter.

[0033] Furthermore, the counterweight mechanism includes:

[0034] The box is hollow inside, and a water inlet is provided on the lower side of the box. The water inlet is used for external water to enter the box and increase the overall weight of the box.

[0035] The counterweight is located at the bottom of the box body;

[0036] A storage cavity is located at the top of the box, and the lower end of the rope is fixedly connected to the inner bottom of the storage cavity. The storage cavity is also used to store the cleaning component.

[0037] Furthermore, the counterweight mechanism is provided with a buoyancy adjustment component, which includes:

[0038] An airbag is located at the top of the box.

[0039] A compressed air cylinder is disposed inside the airbag and is connected to the control component. It is used to inflate the airbag, causing it to expand and expel water from the inside of the box, thereby increasing the buoyancy of the box.

[0040] Furthermore, flow velocity sensors are installed on the outer sides of both the first and second ring pipes, which can monitor the flow velocity of water at different depths and provide data for subsequent water level calculations.

[0041] The working method of this invention is as follows: A support platform is placed on the water surface, and the counterweight mechanism's housing is submerged. Under the weight of the counterweight, the housing moves towards the bottom. During this movement, external water flows into the housing through the inlet, increasing its weight and accelerating its movement to the bottom. After the housing reaches the bottom, a servo motor locks the winding drum. The length of the lowered rope is obtained using a meter counter. To prevent underwater weeds and other debris from tangling on the rope, a clearing mechanism is activated. The second clamping assembly of the second ring tube clamps and secures the rope. Then, the electric telescopic rod of the telescopic assembly extends, causing the first ring tube to move upwards along the rope and away from the second ring tube. During the movement of the first ring tube, the sleeve moves close to the rope surface, allowing it to enter between the debris and the rope. Simultaneously, a drive motor rotates the drive disc, and the actuating element on the drive disc intermittently actuates the driven plate of the clearing plate, causing it to reciprocate along the radial direction of the second ring tube. This causes the cutting plate to reciprocate against the surface of the sleeve, cutting away debris such as weeds on the outside of the sleeve. When the first ring tube moves to its furthest distance from the second ring tube, the first clamping component inside the first ring tube clamps and fixes the rope, while the second clamping component inside the second ring tube releases its clamp on the rope. Then, the electric telescopic rod shortens, causing the second ring tube to move along the rope toward the first ring tube. When the second ring tube moves to its minimum distance from the first ring tube, the above steps are repeated until both the first and second ring tubes have moved to the top of the rope, completing the removal of debris entangled on the rope. At this point, the operator can calculate the water level depth based on the rope's lowering length and bending angle with minimal error. When it is necessary to retract the counterweight mechanism, the compressed air cylinder is controlled to inflate the air bladder, causing the air bladder to expand inside the box and expel the water inside the box through the water inlet. The servo motor is then activated to drive the winding drum to rotate and wind up the rope.

[0042] Compared with existing technologies, the advantages of this invention are as follows: The hydrological engineering geological water level monitoring device provided by this invention, by setting a clearing mechanism on the outside of the rope, can remove aquatic plants and other debris entangled on the underwater rope, preventing these debris from becoming entangled and causing changes in rope bending, which would affect the accuracy of the operator's calculation of the water level based on the rope's curvature, and also affect the rope's retrieval operation. Furthermore, the clearing mechanism is configured with a first ring pipe and a second ring pipe that can be approached and moved away. By fixing the second ring pipe, the first ring pipe can move along the rope, and a leverage point is provided for the clearing component on the first ring pipe, enabling the clearing component to cut and remove the aquatic plants and other debris entangled on the rope. A driving component is also provided that can simultaneously drive multiple cutting plates to perform the cutting operation, enabling omnidirectional cutting of aquatic plants and other debris entangled on the rope, resulting in good removal effect. In summary, this invention has the advantages of novel structure, convenient operation, and high monitoring accuracy. Attached Figure Description

The cleaning assembly 44 is used to remove debris from the rope 2; such as Figure 5As shown, the cleaning assembly 44 includes a sleeve 441, multiple support shafts 442, multiple cleaning plates 443, a drive component 444, and a control component 445. The sleeve 441 is disposed on the side of the second annular tube 42 away from the first annular tube 41, and the sleeve 441 is circumferentially sleeved on the outside of the rope 2. The multiple support shafts 442 are arranged circumferentially on the side of the sleeve 441, and the multiple support shafts 442 are all disposed close to the second annular tube 42. Each cleaning plate 443 has a pivot pin 4431 in the middle, and the pivot pin 4431 is movably disposed in the corresponding support shaft 442. The pivot pin 4431 is connected to the support shaft 442 by a torsion spring. One end of the cleaning plate 443 near the sleeve 441 is a cutting plate 4432, and the other end is a driven plate. 4433, the driven plate 4433 is located inside the second annular tube 42; the driving component 444 is disposed inside the second annular tube 42, and the driving component 444 is used to drive the driven plate 4433 to reciprocate along the radial direction of the second annular tube 42, thereby causing the cutting plate 4432 to reciprocate in contact with the surface of the sleeve 441 to realize the shearing and cleaning action. The driving component 444 includes a bearing 4441, a driven gear 4442, a driving disc 4443, and a driving motor 4445; the inner ring of the bearing 4441 is fixedly sleeved inside the second annular tube 42; the driven gear 4442 is fixedly sleeved on the outer ring edge side of the bearing 4441; the driving disc 4443 is fixedly sleeved on the outer ring edge side of the bearing 4441, such as Figure 6 As shown, the drive disk 4443 has multiple actuating elements 4444 on its edge. The actuating elements 4444 are used to intermittently contact the driven plate 4433 during rotation, thereby driving the driven plate 4433 to reciprocate along the radial direction of the second ring tube 42. The drive motor 4445 is located inside the second ring tube 42 and is electrically connected to the control component 445. The output shaft of the drive motor 4445 is provided with a drive gear 4446, which meshes with the driven gear 4442 to drive the drive disk 4443 to rotate.

[0058] The working method of the above embodiment is as follows: the support platform 11 is placed on the water surface, and the box 31 of the counterweight mechanism 3 is placed in the water. Under the gravity of the counterweight block 32, the box 31 moves towards the bottom of the water. During the movement, external water flows into the box 31 through the water inlet 311, increasing the weight of the box 31 and accelerating the movement of the box 31 to the bottom of the water. After the box 31 moves to the bottom of the water, the servo motor 122 locks the winding drum 121, and the length of the lowering rope 2 is obtained by the meter counter 13. In order to prevent underwater weeds and other debris from getting tangled on the rope 2, the clearing mechanism 4 is activated. The second clamping assembly 421 of the second ring tube 42 clamps and fixes the rope 2. Then, the electric telescopic rod 431 of the telescopic assembly 43 extends, causing the first ring tube 41 to move upward along the rope 2 and away from the second ring tube 42. During the movement of the first ring tube 41, the sleeve 441 moves close to the surface of the rope 2, allowing the sleeve 441 to enter between the debris and the rope 2. At the same time, the drive motor 4445 drives the drive disc 4443 to rotate. The actuating element 4444 on the drive disc 4443 intermittently actuates the driven plate 4433 of the clearing plate 443 along the radius of the second ring tube 42. The direction reciprocates, causing the cutting plate 4432 to reciprocate in contact with the surface of the sleeve 441, cutting away debris such as weeds on the outside of the sleeve 441. When the first ring tube 41 moves to its furthest distance from the second ring tube 42, the first clamping component 411 inside the first ring tube 41 clamps and fixes the rope 2, and the second clamping component 421 inside the second ring tube 42 releases the clamp on the rope 2. Then, the electric telescopic rod 431 shortens, causing the second ring tube 42 to move along the rope 2 towards the first ring tube 41. When the second ring tube 42 moves to its minimum distance from the first ring tube 41... When leaving, repeat the above steps until both the first ring pipe 41 and the second ring pipe 42 have moved to the upper end of the rope 2, completing the removal of debris entangled on the rope 2. At this time, the operator can calculate the water level depth based on the lowering length and bending angle of the rope 2 with a small error. When it is necessary to retrieve the counterweight mechanism 3, control the compressed air cylinder 342 to inflate the air bag 341, so that the air bag 341 expands inside the box 31, and discharges the water inside the box 31 through the water inlet 311. Start the servo motor 122 to drive the winding drum 121 to rotate and wind up the rope 2.
