Technical Field
[0001] This utility model relates to the field of water conservancy engineering surveying technology, specifically a depth measuring instrument for water conservancy and hydropower surveying. Background Technology
[0002] Water conservancy projects are engineering projects built to control and regulate surface water and groundwater in nature to achieve the purpose of eliminating harm and promoting benefits. They are also called water projects. Water is an essential and precious resource for human production and life, but its natural state does not fully meet human needs. Only by building water conservancy projects can we control water flow, prevent floods, and regulate and distribute water to meet the needs of people's life and production for water resources.
[0003] A common method for measuring water depth involves using a motor-driven take-up roller to lower the measuring device into the water via a winding measuring rope. For example, Chinese patent application number 202221450563.7 discloses a portable water level measuring device for the operation and management of water conservancy projects. The device includes a transportation mechanism, comprising a base with a moving component for mobile transportation below the base; a measuring mechanism, comprising a measuring component on top of the base for efficient measurement, the measuring component consisting of a measuring instrument and a probe, the probe being fixedly connected to the lower end of the measuring instrument, and supports at both ends of the measuring instrument for stable measurement; and a storage mechanism, comprising a data box fixed to the upper surface of the base for storing measurement data, with a sliding component inside the data box for quick storage and retrieval. Through the provided measuring component, the device achieves high efficiency and more performance-oriented measurement, enabling high-accuracy measurement of water conservancy equipment at different depths. This not only improves the device's measurement efficiency but also further enhances its measurement performance.
[0004] However, after measuring the water level, the existing water depth measuring device has a lot of impurities on the measuring ruler (rope) in the water. It is not convenient to clean it when winding it up, and the impurities are easy to stick to the take-up roller, which affects the subsequent use. Moreover, if it is not cleaned in time, it will corrode the measuring ruler, reduce its lifespan, and reduce its practicality. Therefore, we propose a depth measuring instrument for water conservancy and hydropower exploration. Utility Model Content

Through the cooperation of the first slider 15, the telescopic spring 16 and the limiting groove 13, the insert block 11 can be limited, thereby limiting the two cleaning rollers 12, which facilitates the disassembly and replacement of the two cleaning rollers 12 and improves the practicality of the depth measuring instrument for water conservancy and hydropower exploration.
[0021] An assembly box 20 is fixedly connected to the top of the base 1. A counterweight 21 is inserted into the inside of the assembly box 20. Two corresponding second slide grooves 22 are opened inside the assembly box 20. A second slider 23 is inserted into the inside of the second slide grooves 22. A fixing bolt is provided inside the assembly box 20. The assembly box 20 and the second slider 23 are fixed by the fixing bolt. The counterweight 21 inserted into the assembly box 20 can be fixed by the second slide grooves 22, the second slider 23 and the fixing bolt.
[0022] Multiple connecting brackets 29 are fixedly connected to the outer side of the mounting rod 3 and the mounting plate 5. Multiple guide rollers 9 are rotatably connected inside the connecting brackets 29. The measuring scale can be guided by multiple sets of guide rollers 9 to avoid the measuring scale from being skewed or knotted.
[0023] The rotating frame 2 has a rotating roller 28 rotatably connected inside, and the mounting rod 3 is fixedly connected to the outside of the rotating roller 28. The rotating frame 2 has a second servo motor 27 fixedly installed inside, and the output end of the second servo motor 27 is fixedly connected to the rotating roller 28.

[0024] A take-up frame 24 is fixedly connected to the top of the base 1. A take-up roller 25 is rotatably connected inside the take-up frame 24.

A measuring scale is wound around the outside of the take-up roller 25.
[0025] The connecting block 6 has a slot 17 inside, and a push block 19 is inserted into the slot 17. The push block 19 and the slot block 18 cooperate with each other. A mounting block 30 is fixedly connected to the top of the mounting rod 3. A third slide groove 31 is opened inside the mounting block 30. A third slider 33 is slidably connected inside the third slide groove 31. A reciprocating screw 32 is set inside the third slide groove 31.

[0026] In summary, when using this depth measuring instrument for hydropower surveying, the operator moves it to the measuring position via the universal self-locking wheels and handle on the outer side of the base 1. Then, the control device activates the second servo motor 27 to drive the rotating roller 28 to rotate, which in turn drives the mounting rod 3 to rotate. Simultaneously, the electric telescopic rod 4 extends and retracts, adjusting the lowering position of the counterweight measuring head. After measurement, when rewinding the measuring scale, the scraper 8 removes larger debris adhering to the outer side of the measuring scale. Smaller debris is then removed by the adhesive sleeves on the outer sides of the two cleaning rollers 12. Finally, the control device activates the second servo motor 35 to drive the reciprocating screw 32 to rotate, thereby... The third slider 33 and guide sleeve 34 reciprocate to guide the measuring scale. The speed of the third slider 33 and guide sleeve 34 is proportional to the winding speed of the measuring scale. When the cleaning roller 12 needs to be disassembled and replaced, the push block 18 drives the first slider 15 to slide into the first groove 14, causing the telescopic spring 16 to contract and pull the first slider 15 out of the limiting groove 13, releasing the limiting of the plug-in block 11. Then, the push block 19 is pushed so that the push block 19 passes through the groove 17 and contacts the bottom of the block 18, thereby limiting the block 18 and preventing the telescopic spring 16 from rebounding. Then, the plug-in block 11 can be disassembled. The counterweight measuring head is an MS5837 water depth sensor, which is existing technology and will not be described in detail.
[0027] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
