[0002] Water level monitoring in water conservancy projects is a complex and sophisticated process designed to ensure the efficient use and management of water resources. This process typically involves continuous monitoring of water levels in various water bodies, such as reservoirs, rivers, and lakes. The purpose of monitoring is not only for day-to-day management but also to provide early warnings in the face of extreme weather events and mitigate the losses caused by natural disasters. For example, by monitoring water levels before the rainy season arrives, potential floods can be predicted, allowing for proactive flood prevention preparations.

[0003] In water conservancy projects, water level detection devices are important tools to ensure effective water resource management and disaster warning. In order to adapt to the ever-changing water flow environment, a pipeline system is usually deployed to assist the detection device. The purpose of the design of the pipeline system is to protect the detection device from the impact of water flow and other environmental factors, thereby ensuring its stability and measurement accuracy. However, over time, scaling will appear on the inner wall of the pipe, especially in environments where the water contains more nutrients. This situation provides favorable conditions for the growth of aquatic plants, resulting in the water level monitoring results being affected. How to invent a water level detection device for water conservancy projects to improve these problems has become an urgent problem to be solved by technicians in this field. Utility Model Content

A plurality of fixing rods 13 are fixedly connected to the side wall of the base 1. A circular hoop 14 is fixedly connected to the end of the fixing rod 13. The circular hoop 14 is fixedly connected to the long tube 9. A plurality of water flow covers 15 are fixedly connected to the outer wall of the long tube 9. A scraping assembly and a knocking assembly are provided inside the long tube 9. One side of the guide plate 8 is fixedly connected to the outer wall of the long tube 9. The counterweight 12 and the float 11 are located on the inner side of the long tube 9. The float 11 is made of hollow plastic material, and the counterweight 12 is made of solid metal material.

[0025] The scraping assembly includes a plurality of holding rings 16 rotatably connected to the outer wall of the long tube 9, the outer walls of the plurality of holding rings 16 are fixedly connected with support shafts 17, the ends of the support shafts 17 are fixedly connected with water flow plates 18, the inner walls of the holding rings 16 are fixedly connected with a plurality of support rods 19, the ends of the support rods 19 are fixedly connected with scrapers 20, the support shafts 17 and the water flow plates 18 are equidistantly arranged on the outer wall of the holding ring 16, and the support rods 19 and the scrapers 20 are equidistantly arranged on the inner wall of the holding ring 16. The scraper 20 is arranged in a long strip shape, and the blade of the scraper 20 is arranged in contact with the side wall of the long tube 9; the knocking assembly includes a plurality of stabilizing rods 21 fixedly connected to the inner wall of the long tube 9, the ends of the plurality of stabilizing rods 21 are fixedly connected to a baffle 22, the ends of the baffle 22 are fixedly connected to a plurality of springs 23, the ends of the springs 23 are fixedly connected to a swing rod 24, the balance hammer 12 and the float 11 are located on both sides of the baffle 22, and the swing rod 24 and the support rod 19 are arranged in the same horizontal plane.

[0026] The working principle of the water level detection device for a water conservancy project is as follows: the device is installed on the river bank, and the float 11 floats on the water surface. When the water level rises, the float 11 also rises. At this time, due to the traction of the counterweight 12, when the float 11 rises, the cable 7 moves and drives the wheel 6 to rotate. The rotation action is finally fed back to the conversion box 4, which displays the current water level height.

[0027] In the flowing river, by setting the diversion plate, the water flow only passes through one side of the long tube 9, and the water flow impacts multiple water flow plates 18. The water flow plate 18 drives the holding ring 16 to rotate through the support shaft 17, and the holding ring 16 drives the scraper 20 to do a circular motion through the support rod 19. The scraper 20 continuously scrapes the inner wall of the long tube 9 to keep the inner wall of the long tube 9 in a clean state, preventing scale from accumulating inside the long tube 9 and preventing grass seeds from adhering to the inner wall of the long tube 9 and causing the growth of aquatic plants, thereby ensuring that the water level measurement is not affected by the entanglement of aquatic plants and the measurement accuracy.

[0028] Furthermore, when multiple scrapers 20 make circular motion, the scraper 20 will push the swing rod 24 when passing the position of the swing rod 24, causing the spring 23 to deform. When the scraper 20 separates from the swing rod 24, the spring 23 resets, and the swing rod 24 hits another scraper 20 that moves relative to it, causing the scraper 20 to vibrate, thereby shaking off the scale and other residues scraped off by the scraper 20, keeping the surface of the scraper 20 clean, and continuously maintaining the scraper 20's effect of cleaning scale.

[0029] It should be noted that the specific model and specifications of the motor need to be selected and determined based on the actual specifications of the device, and the specific selection calculation method adopts the existing technology in this field, so it will not be described in detail.

[0030] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
