Abstract
Description
Technical Field
[0001] This utility model relates to the field of water level monitoring technology, specifically to a mobile water level monitoring device for water conservancy projects. Background Technology
[0002] In the field of water conservancy projects, water level monitoring is a crucial link, which is related to many aspects such as water resource allocation, flood control and drought relief, and the safe operation of water conservancy facilities. By monitoring the water level, it is convenient to conduct accurate analysis and comparison of water level conditions in different areas, which has important guiding significance for the planning of water conservancy projects and flood control and prevention work.
[0003] In real-world scenarios, mobile water level monitoring devices require a relatively complex structure to ensure normal water level detection. Furthermore, in waters with poor water quality and a lot of floating debris, the lack of relevant filtration and cleaning functions allows impurities to enter the device and adhere to its surface, leading to sensor blockage, reduced detection accuracy, and the inability to provide reliable water level data. Utility Model Content
[0004] In view of the above-mentioned shortcomings of the existing technology, this utility model provides a mobile water level monitoring device for water conservancy projects, which can effectively solve the problem that the existing technology cannot accurately measure the water level in waters with a lot of impurities.
[0005] To achieve the above objectives, this utility model provides the following technical solution:
[0006] This utility model provides a mobile water level monitoring device for water conservancy projects, including: a detection mechanism, a driving mechanism inside the detection mechanism, and an adjustment mechanism on one side of the driving mechanism;
[0007] The detection mechanism includes a floating shell, a partition fixed in the middle of the inner cavity of the floating shell, a positioning device fixed at the upper end of the partition, a pumping device fixed at the upper end of the partition, a plurality of floating airbags fixed in an array at the lower end of the partition, a blocking ring rotatably connected to the outer surface of the floating shell, a plurality of filter holes arranged in a circumferential array on the outer surface of the blocking ring, and a plurality of cleaning racks fixed in an array at the upper end of the blocking ring.
[0008] Preferably, both the output and input ends of the pumping device are fixed with pipes.
[0009] Preferably, the driving mechanism includes a sealed housing fixed to the lower end of the partition plate. A water inlet hole is provided on one side of the outer surface of the sealed housing, and a water outlet hole is provided on the other side of the outer surface of the sealed housing. A rotating blade is rotatably connected inside the sealed housing. An arc-shaped groove is provided on the end faces of the rotating blades that are close to each other. A connecting rod that penetrates the sealed housing is fixed inside the rotating blade.
[0010] Preferably, the water outlet is fixedly connected to a pipe near the input end of the pumping device, and the lower end of the connecting rod is fixedly connected to a blocking ring.
[0011] Preferably, the adjustment mechanism includes a connecting pipe communicating with the water inlet, a fixed pipe fixed inside the connecting pipe, a plurality of open holes arranged in a circumferential array on the outer surface of the fixed pipe, a movable pipe slidably connected to the outer surface of the fixed pipe, an electromagnetic block fixed to the horizontal end face of the open hole near the movable pipe, and a permanent magnet block fixed to the horizontal end face of the movable pipe near the open hole.
[0012] Preferably, the electromagnetic block and the permanent magnet block are magnetically repulsive.
[0013] The technical solution provided by this utility model has the following advantages compared with the known prior art:
[0014] By using a positioning device and a floating airbag in conjunction, the water level in the water area can be detected effectively. The pumping device draws water to drive the blocking ring and cleaning frame to rotate, preventing impurities in the water from being adsorbed and entering the device, thus avoiding blockage or damage to subsequent detection components. The adsorption and retention of impurities will not increase the overall weight of the device, ensuring normal operation and detection accuracy.

[0022] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.
[0023] The present invention will be further described below with reference to the embodiments.
[0024] Example: Refer to Figures 1 to 5 A mobile water level monitoring device for water conservancy projects includes: a detection mechanism 1, a drive mechanism 2 inside the detection mechanism 1, and an adjustment mechanism 3 on one side of the drive mechanism 2.
[0025] To further explain, the following settings are implemented for better water level detection, such as... Figure 3 As shown, the detection mechanism 1 includes a floating shell 11. A partition is fixed in the middle of the inner cavity of the floating shell 11. A positioning device 12 is fixed at the upper end of the partition. A pumping device 13 is also fixed at the upper end of the partition. Pipes are fixed at both the output end and the input end of the pumping device 13. Multiple floating airbags 14 are fixed in an array at the lower end of the partition. A blocking ring 15 is rotatably connected to the outer surface of the floating shell 11. Multiple filter holes 16 are arranged in a circumferential array on the outer surface of the blocking ring 15. Multiple cleaning racks 17 are fixed in an array at the upper end of the blocking ring 15.
[0026] To further explain, the following settings are implemented to facilitate the removal of impurities from the water by the components within the testing mechanism 1, such as... Figure 4As shown, the drive mechanism 2 includes a sealed housing 21 fixed to the lower end of the partition. A water inlet hole 22 is provided on one side of the outer surface of the sealed housing 21, and a water outlet hole 23 is provided on the other side of the outer surface of the sealed housing 21. The water outlet hole 23 is fixedly connected to a pipe near the input end of the pumping device 13. A rotating blade 24 is rotatably connected inside the sealed housing 21. Arc-shaped grooves 25 are provided on the end faces of the rotating blades 24 that are close to each other. A connecting rod 26 that penetrates the sealed housing 21 is fixed inside the rotating blade 24. The lower end of the connecting rod 26 is fixedly connected to the blocking ring 15.
[0027] To further explain, the following settings are made to adjust the rotational speed of the blocking ring 15, such as... Figure 5 As shown, the adjustment mechanism 3 includes a connecting pipe 31 that communicates with the water inlet 22. A fixed pipe 32 is fixed inside the connecting pipe 31. Multiple open holes 33 are arranged in a circumferential array on the outer surface of the fixed pipe 32. A movable pipe 34 is slidably connected to the outer surface of the fixed pipe 32. An electromagnetic block 35 is fixed to the horizontal end face of the open hole 33 near the movable pipe 34. A permanent magnet block 36 is fixed to the horizontal end face of the movable pipe 34 near the open hole 33. The electromagnetic block 35 and the permanent magnet block 36 repel each other magnetically.
[0028] The working principle of this utility model is as follows: When the device is placed in the water, the multiple floating airbags 14 set inside the floating shell 11 can significantly increase the buoyancy of the device, so that the entire water level monitoring device floats stably on the water surface. Whether in a calm lake or a relatively turbulent river, the device can be guaranteed not to sink easily, ensuring the continuous monitoring work. The positioning device 12 can accurately determine the position of the device on the water surface, providing accurate geographical coordinate information for water level data, which is convenient for subsequent accurate analysis and comparison of water level conditions in different areas, and can also determine the water level height in the water area.
[0029] While the device operates in the water, the pumping device 13 needs to be activated to draw water from the water through the pipe. The water flow first enters the connecting pipe 31, and then powers the electromagnetic block 35. Utilizing the principle of magnetic repulsion between the electromagnetic block 35 and the permanent magnet block 36, the electromagnetic block 35 can push the permanent magnet block 36 and the movable pipe 34 to move away from the fixed pipe 32, so that the movable pipe 34 no longer seals the open hole 33. This allows the water flow to enter the sealed housing 21 through the open hole 33 and the connecting pipe 31. The rotating blade 24 located in the sealed housing 21 rotates due to the impact of the water flow when the water flows through the inlet hole 22 and the outlet hole 23. This causes the blocking ring 15 and the cleaning frame 17 to rotate. The filter holes 16 on the outer surface of the blocking ring 15 can filter the water entering the device and intercept larger impurities in the water. The cleaning frame 17 can drive away impurities floating on the water surface and prevent them from adhering to the surface of the device, thereby affecting the detection effect of the device.
[0030] When encountering water with a high concentration of impurities, the current flowing into the blocking ring 15 can be increased, thus increasing its magnetism. This, in turn, pushes the permanent magnet block 36 and the movable tube 34 a greater distance, increasing the contact between the open hole 33 and the connecting tube 31. Without changing the pumping force of the pumping device 13, the water flow rate entering the connecting tube 31 and the sealing housing 21 can be increased, thereby increasing the rotation speed of the rotating blade 24. This allows the rotating blade 24 to drive the blocking ring 15 and the cleaning frame 17 to rotate faster, ensuring that impurities in the water will not affect the normal use of the device, avoiding blockage or damage to subsequent detection components, and preventing the adsorption and retention of impurities from increasing the overall weight of the device, thus ensuring the normal operation and detection accuracy of the device.
[0031] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of this utility model.
