The main purpose is to solve the problem that water level columns are installed in the water, making them inconvenient to move and difficult to measure other locations when necessary, thus causing inconvenience in measurement.

[0006] Technical solution

[0007] To achieve the above objectives, the present invention provides the following technical solution:

[0008] A water level measuring device for dam monitoring includes a float frame. A fixing mechanism is provided on one side of the float frame to secure it to the dam. A winding roller is rotatably connected between the inner walls of both sides of the float frame. A connecting rope is wound around the outer circumference of the winding roller. A wire-passing hole is provided on the bottom outer wall of the float frame, and one end of the connecting rope passes through the wire-passing hole and is positioned to insert into the mud at the bottom of the water body. A worm gear is fixed to one side of the winding roller via a coupling. A fixing tube is welded to the bottom inner wall of the float frame, and a worm wheel is rotatably connected to the top of the fixing tube, meshing with the worm. A threaded rod is slidably connected inside the fixing tube, and one end of the threaded rod passes through the worm wheel and is fixed to a marking frame by bolts. The threaded rod is threadedly connected to the worm wheel. A fixing rod is welded to the top of the float frame, and a scale is provided at the upper end of the fixing rod. The marking frame is fitted around the outer circumference of the fixing rod and cooperates with the scale. Airbags are adhered to all four outer walls of the float frame.

[0009] Furthermore, the fixing mechanism includes two sliding holes, which are opened on the bottom outer wall of the floating plate frame. Sliding rod assemblies are slidably connected in both sliding holes. The top of the sliding rod assembly is provided with an installation frame that is fixed to the dam, and the sliding rod assembly and the installation frame are connected by a connecting component.

[0010] Based on the aforementioned scheme, the slide rod assembly includes multiple connecting rods, with a first threaded hole at the top of the connecting rod and a first threaded rod welded to the bottom of the connecting rod. The first threaded rods between two adjacent connecting rods are threaded into the first threaded hole. The connecting assembly includes two second threaded rods, which are welded to the bottom of the mounting bracket and can be tightened into the first threaded hole.

[0011] As a further embodiment of the present invention, the bottom of the connecting rod at the bottom end is provided with a first cone head, the top of the first cone head is provided with a second threaded hole, and the first threaded rod at the bottom of the connecting rod at the bottom end can be screwed into the second threaded hole.

[0012] Furthermore, the positioning mechanism includes a second cone head, which is wound around one end of the connecting rope. Multiple pressure plates are welded to the top of the second cone head, and the multiple pressure plates are evenly distributed.

[0013] Based on the aforementioned scheme, a connecting shaft is fixed to one side of the take-up roller via a coupling, and a turntable frame is fixed to one end of the connecting shaft via bolts. A locking mechanism is provided on one side of the float frame to fix the rotation of the connecting shaft.

[0014] As a further embodiment of the present invention, the locking mechanism includes multiple slots, which are formed on the outer circumference of the connecting shaft. A clearance groove is formed on the outer circumference of the connecting shaft, and the clearance groove is connected to the slot. A fixed shaft is fixed to one side of the float frame by bolts. A connecting frame is sleeved on the outer circumference of the fixed shaft. A slip ring is rotatably connected to one end of the connecting frame, and the slip ring is sleeved on the outer circumference of the connecting shaft. Multiple locking blocks are welded to the inner circumference of the slip ring, and the locking blocks can be locked into the slots. A limiting mechanism for fixing the position of the connecting frame is provided on one side of the fixed shaft. A torsion spring is fixed to the outer circumference of the slip ring by bolts, and the other end of the torsion spring is fixed to the connecting frame.

[0015] Furthermore, the limiting mechanism includes two mounting slots, both of which are opened on the outer circumference of the fixed shaft. An elastic ball is bonded to each of the two mounting slots. An arc-shaped groove is opened on the inner circumference of one end of the connecting frame, and one of the elastic balls is located in the arc-shaped groove.

[0016] Based on the aforementioned scheme, an infrared rangefinder is provided at the bottom of the mounting frame, and a receiving plate is welded to one side of the floating plate frame.

[0017] Beneficial effects

[0018] Compared with the prior art, the present invention provides a water level measuring device for dam monitoring, which has the following beneficial effects:

[0019] 1. This invention features a scale and a marking frame. The rotation of the winding roller drives the worm gear to rotate, which in turn causes the worm wheel to rotate, thus moving the threaded rod upward and consequently moving the marking frame upward. This allows the value on the scale to be confirmed, and the water level height to be calculated. The measuring device can be removed and repositioned at any time to measure the water level at different locations, improving the applicability of the device.

[0020] 2. The present invention has a fixing mechanism that inserts the first cone into the soil and the mounting frame is fixed to the dam with bolts, so that the floating plate frame can slide easily on the sliding rod and will not move with the water flow, making it easy to collect and thus ensuring the accuracy of the measurement.

[0021] 3. By incorporating a positioning mechanism, the second cone head is inserted into the soil, and the pressure plate expands the contact area between the second cone head and the soil, thereby preventing the second cone head from moving within the soil and further improving the accuracy of the device's measurements.

[0022] 4. This invention features a locking mechanism. The moving connecting frame drives the moving slip ring, causing the locking block to engage with the slot. This allows the rotation of the connecting shaft to drive the rotation of the slip ring. A torsion spring limits the rotation of the slip ring. Once the connecting shaft is stable, data can be read and water level measured. Attached Figure Description

[0033] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] Reference Figures 1-9A water level measuring device for dam monitoring includes a float frame 1. Airbags 14 are adhered to the outer walls of the float frame 1. A fixing mechanism for securing the float frame 1 to the dam is provided on one side of the float frame 1. A winding roller 12 is rotatably connected between the inner walls of the two sides of the float frame 1. A connecting rope 11 is wound around the outer circumference of the winding roller 12. A wire hole 15 is provided on the bottom outer wall of the float frame 1, and one end of the connecting rope 11 passes through the wire hole 15 and is positioned to insert into the mud at the bottom of the water body. A worm gear 23 is fixed to one side of the winding roller 12 via a coupling. A fixing pipe 22 is welded to the bottom inner wall of the float frame 1. A worm wheel 21 is rotatably connected to the top of the fixing pipe 22, and the worm wheel 21 meshes with the worm gear 23. A threaded rod 20 is slidably connected inside the fixing pipe 22, and one end of the threaded rod 20 passes through the worm wheel 21 and is fixed by bolts. The device includes a marker frame 19, and a threaded rod 20 is threadedly connected to a worm gear 21. A fixing rod 13 is welded to the top of the float frame 1, and a scale 18 is provided at the upper end of the fixing rod 13. The marker frame 19 is fitted around the outer circumference of the fixing rod 13 and cooperates with the scale 18. In use, the float frame 1 is installed on the dam through the fixing mechanism, and the positioning mechanism is inserted into the mud at the bottom of the water body. The float frame 1 floats up due to buoyancy, which causes the winding roller 12 to rotate. The rotation of the winding roller 12 drives the worm gear 23 to rotate, which in turn causes the worm gear 21 to rotate, thereby moving the threaded rod 20 upward and driving the marker frame 19 upward, thus confirming the value on the scale 18. The water level is calculated, and the measuring device can be removed and repositioned at any time to measure the water level at different locations, improving the applicability of the device.

[0035] Furthermore, the fixing mechanism includes two sliding holes, which are formed on the bottom outer wall of the floating plate frame 1. A sliding rod assembly is slidably connected within each sliding hole. The top of the sliding rod assembly is equipped with a mounting frame 2 fixed to the dam. The sliding rod assembly and the mounting frame 2 are connected via a connecting component. The sliding rod assembly includes multiple connecting rods 3. A first threaded hole 7 is formed at the top of each connecting rod 3, and a first threaded rod 6 is welded to the bottom of each connecting rod 3. The first threaded rod 6 between adjacent connecting rods 3 is threaded into the first threaded hole 7. The connecting component includes two second threaded rods 8, which are welded to the bottom of the mounting frame 2 and can be tightened into the first threaded hole 7. The bottommost connecting rod... The bottom of the connecting rod 3 is provided with a first cone head 5, and the top of the first cone head 5 is provided with a second threaded hole 10. The first threaded rod 6 at the bottom of the connecting rod 3 at the bottom end can be screwed into the second threaded hole 10. In use, the first cone head 5 is connected to the connecting rod 3 at the bottom end, so that the connecting rod 3 at the bottom end passes through the sliding hole. Then, the connecting rods 3 are connected in sequence for assembly, so that multiple connecting rods 3 form a sliding rod. After a certain length, the connecting rod 3 at the top end is connected to the mounting frame 2. The first cone head 5 is inserted into the soil. The mounting frame 2 is fixed to the dam with bolts, so that the floating plate frame 1 can slide easily on the sliding rod and will not move with the water flow, making it easy to retrieve and thus ensuring the accuracy of the measurement.

[0036] Furthermore, the positioning mechanism includes a second cone 17, which is wound around one end of the connecting rope 11. Multiple pressure plates 16 are welded to the top of the second cone 17 and are evenly distributed. When the second cone 17 is inserted into the soil, the pressure plates 16 will increase the contact area between the second cone 17 and the soil, thereby preventing the second cone 17 from moving in the soil and further improving the accuracy of the device's measurement.

[0037] Furthermore, a connecting shaft 25 is fixed to one side of the take-up roller 12 via a coupling. One end of the connecting shaft 25 is fixed to a turntable frame 26 via bolts. A locking mechanism for fixing the rotation of the connecting shaft 25 is provided on one side of the float frame 1. The locking mechanism includes multiple slots 28, which are formed on the outer circumference of the connecting shaft 25. A clearance groove 27 is formed on the outer circumference of the connecting shaft 25, and the clearance groove 27 communicates with the slots 28. A fixing shaft 32 is fixed to one side of the float frame 1 via bolts. A connecting frame 31 is sleeved on the outer circumference of the fixing shaft 32. One end of the connecting frame 31 is rotatably connected to a slip ring 29, which is fitted around the outer circumference of the connecting shaft 25. Multiple locking blocks 30 are welded to the inner circumference of the slip ring 29, and these blocks 30 can be engaged in slots 28. A limiting mechanism for fixing the position of the connecting frame 31 is provided on one side of the fixed shaft 32. A torsion spring 24 is fixed to the outer circumference of the slip ring 29 by bolts, and the other end of the torsion spring 24 is fixed to the connecting frame 31. The limiting mechanism includes two mounting slots 33, both located on the outer circumference of the fixed shaft 32. Each component is bonded with an elastic ball 34. An arc-shaped groove 35 is formed on the inner circumference of one end of the connecting frame 31, with one elastic ball 34 located within the arc-shaped groove 35. When the second cone 17 is submerged in water, the connecting frame 31 slides, causing the sliding ring 29 to move, thereby disengaging the locking block 30 from the locking groove 28. This allows the sliding ring 29 to be positioned within the clearance groove 27. At this time, the rotation of the connecting shaft 25 does not cause the sliding ring 29 to rotate. After the second cone 17 is inserted into the mud, the connecting frame 31 slides in the reverse direction, causing the sliding ring 29 to move, thus disengaging the locking block 30 from the locking groove 28. The connecting shaft 25 rotates, causing the slip ring 29 to rotate. The rotation of the slip ring 29 is limited by the torsion spring 24. Once the connecting shaft 25 is stable, data can be read and the water level can be measured. During the movement of the connecting frame 31, the arc-shaped groove 35 will squeeze the elastic ball 34, causing the elastic ball 34 to deform and thus allowing the elastic ball 34 to disengage from the arc-shaped groove 35. When the connecting frame 31 moves to another position, another elastic ball 34 can be inserted into the arc-shaped groove 35, thereby fixing the position of the connecting frame 31.

[0038] Furthermore, an infrared rangefinder 9 is installed at the bottom of the mounting frame 2, and a receiving plate 4 is welded to one side of the floating plate frame 1. The infrared rangefinder 9 can measure the height of the exposed dam, thereby helping to determine the water level.

[0039] The working principle of this embodiment is as follows: In use, the first cone head 5 is connected to the bottommost connecting rod 3, allowing the bottommost connecting rod 3 to pass through the sliding hole. Then, the connecting rods 3 are connected sequentially for assembly, forming a sliding rod from multiple connecting rods 3. After a certain length, the topmost connecting rod 3 is connected to the mounting frame 2. The first cone head 5 is inserted into the soil, and the mounting frame 2 is fixed to the dam with bolts, allowing the floating plate frame 1 to slide easily on the sliding rod without moving with the water flow. Then, the second cone head 17 is inserted into the soil, and the pressure plate 16 expands. The contact area between the second cone 17 and the soil is increased, thus preventing the second cone 17 from moving within the soil. When the second cone 17 moves downward, it drives the take-up roller 12 to rotate. The rotation of the take-up roller 12 drives the worm gear 23 to rotate, which in turn drives the worm wheel 21 to rotate, thereby causing the threaded rod 20 to move upward, which in turn drives the marking frame 19 to move upward, thus confirming the value on the scale 18. The water level height is calculated, and the measuring device can be removed and repositioned at any time to measure the water level at different locations, improving the applicability of the device.
