DETAILED DESCRIPTION

[0023] See also Figure 1-Figure 5 A water level detection device for a water conservancy project includes a water level detection mechanism 100 and a buffer mechanism 200 and a lifting mechanism 300 respectively arranged at the bottom and top of the water level detection mechanism 100. The water level detection mechanism 100 includes a positioning cylinder 101:

[0024] Furthermore, a benchmark rod 102 is slidably connected to the lower part of the water level detection mechanism 100, and the lower part of the benchmark rod 102 extends to the lower part of the outside of the positioning cylinder 101 and is slidably connected thereto. A mounting groove 103 is provided at the bottom of the benchmark rod 102, and a liquid level sensor 104 is fixedly installed inside the mounting groove 103. A lifting threaded rod 105 is threadedly connected to the inner wall above the benchmark rod 102, and the top of the lifting threaded rod 105 extends to the outside of the upper part of the positioning cylinder 101 and is fixedly connected to a first motor 106. A first sealing cover 107 is provided on the outside of the first motor 106, and the bottom of the first motor 106 and the first sealing cover 107 are fixedly connected to the top of the positioning cylinder 101.

[0025] The positioning cylinder 101 serves as the basic part of the entire water level detection mechanism 100, providing structural support and being used to protect and position internal components. The benchmark 102 is located below the inside of the positioning cylinder 101 and can move up and down through a sliding connection. The lower end of the benchmark 102 extends out of the positioning cylinder 101 to better contact the water surface. The mounting groove 103 is opened at the bottom of the benchmark 102 for fixedly installing the liquid level sensor 104. The liquid level sensor 104 is used to directly measure the water level height. The lifting threaded rod 105 is connected to the upper inner wall of the benchmark 102 by a thread, and can move the benchmark 102 up and down along the positioning cylinder 101 by rotation. The first motor 106 drives the lifting threaded rod 105 to rotate, thereby controlling the lifting and lowering of the benchmark 102. The first sealing cover 107 is used to protect the first motor 106 from moisture intrusion and ensure the reliability of the first motor 106.

[0026] The advantage of this design is that it can dynamically adjust the position of the liquid level sensor 104 so that it always remains within an effective measurement range. Even if the water level changes significantly, the first motor 106 drives the lifting threaded rod 105, which can make the entire system have better flexibility and accuracy. At the same time, the use of the first sealing cover 107 improves the waterproof performance of the equipment and enhances its working stability in harsh environments.

[0027] Furthermore, connecting blocks 108 are fixedly connected to the left and right sides of the top of the benchmark 102, and lifting limit rods 109 are fixedly connected to the left and right sides of the inner wall of the positioning cylinder 101. The connecting blocks 108 and the lifting limit rods 109 are slidably connected, and a transparent observation window 110 is embedded in the front surface of the positioning cylinder 101.

[0028] The lifting limit rod 109 is fixed on the left and right sides of the inner wall of the positioning cylinder 101, and is used in conjunction with the connecting block 108 to play a guiding and limiting role. When the benchmark 102 moves up and down, the connecting block 108 slides along the lifting limit rod 109, which not only limits the moving trajectory of the benchmark 102, but also prevents the benchmark 102 from producing unnecessary lateral swings when the water level fluctuates. A transparent observation window 110 is embedded in the front surface of the positioning cylinder 101. The main purpose of this design is to allow the operator to intuitively see the position of the benchmark 102 from the outside, which is convenient for inspection or correction.

[0029] Furthermore, the buffer mechanism 200 includes a floating block 201 that is slidably mounted on the surface below the benchmark 102. The top of the floating block 201 is connected to a plurality of buffer rods 202 in a circular array. The surfaces of the plurality of buffer rods 202 are slidably connected to a plurality of fixed sleeves 203. The plurality of fixed sleeves 203 are rotatably mounted on the bottom of the positioning cylinder 101 in a circular array.

[0030] The design of the float 201 enables it to float freely as the water level changes, playing a certain buffering role. At the same time, it can help the device maintain balance when the water level changes and reduce the impact of additional forces caused by water flow on the benchmark 102.

[0031] Furthermore, buffer springs 204 are provided inside the fixing sleeves 203 , one end of the buffer springs 204 is fixedly connected to one end of the buffer rod 202 , and the other end of the buffer springs 204 is fixedly connected to one side of the inner wall of the fixing sleeves 203 .

[0032] The buffer rod 202 is connected to the top of the float 201 in a circular array. This layout allows the buffer rod 202 to act in different directions to disperse the impact force of water flow from different angles. The fixed sleeve 203 is also arranged in a circular array and is set at the bottom of the positioning cylinder 101 by rotation. Each fixed sleeve 203 is slidably connected to the corresponding buffer rod 202, which means that the buffer rod 202 can slide in the fixed sleeve 203. When the water flow hits the buffer rod 202, the buffer rod 202 will slide in the fixed sleeve 203 and compress the buffer spring 204. The elastic deformation of the buffer spring 204 can absorb part of the impact energy, thereby reducing the impact of the water flow on the entire device, especially the liquid level sensor 104. This design not only improves the measurement accuracy of the device, but also extends its service life. It is very suitable for application in various water conservancy projects.

[0033] Furthermore, the lifting mechanism 300 includes lifting links 301 rotatably connected to the left and right sides of the surface of the positioning cylinder 101. The two lifting links 301 are designed to be symmetrically inclined on the left and right sides. The tops of the two lifting links 301 are rotatably connected to threaded blocks 302, and the inner walls of the two threaded blocks 302 are threadedly connected to the same bidirectional threaded rod 303.

[0034] The lifting link 301 is connected to the left and right sides of the surface of the positioning cylinder 101 by rotation, and is designed to be symmetrically tilted on both sides to ensure that the benchmark 102 remains balanced during the lifting process, avoiding deviation or tilting due to uneven force on one side. The inner wall of the threaded block 302 is threadedly connected to the bidirectional threaded rod 303. When the bidirectional threaded rod 303 rotates, the threaded block 302 will move along its axial direction, thereby driving the lifting link 301 to move up and down.

[0035] Furthermore, both ends of the bidirectional threaded rod 303 are rotatably connected to the fixed plate 304, one end of the bidirectional threaded rod 303 extends to the outside of the fixed plate 304 and is fixedly connected to the second motor 305, and a second sealing cover 306 is provided on the outside of the second motor 305, and one side of the second motor 305 and the second sealing cover 306 is fixedly connected to one side of the fixed plate 304.

[0036] The fixing plate 304 is used to fix the two ends of the bidirectional threaded rod 303 to ensure that it does not deviate or vibrate during rotation. The second motor 305 is used to drive the bidirectional threaded rod 303 to rotate. The second sealing cover 306 is used to protect the second motor 305 to prevent water or other impurities from entering the second motor 305 and ensure the normal operation of the second motor 305. Through this design, the lifting mechanism 300 can accurately control the up and down movement of the benchmark 102 to ensure that the liquid level sensor 104 is always within the effective measurement range. The combination of the bidirectional threaded rod 303 and the threaded block 302, plus the symmetrically inclined lifting link 301, can greatly improve the response speed and stability of the device when the water level changes, thereby improving the accuracy and reliability of water level detection. At the same time, the use of the second sealing cover 306 also increases the protection level of the entire system, making it more suitable for long-term and stable operation in outdoor and water environments.

[0037] Furthermore, a horizontal limiting rod 307 is fixedly connected between the sides of the fixing plates 304 that are close to each other, and the horizontal limiting rod 307 is slidably connected to the inner wall of the threaded block 302 .

[0038] Through the guiding effect of the horizontal limit rod 307, the threaded block 302 can only move linearly along the horizontal limit rod 307 under the drive of the bidirectional threaded rod 303, thereby avoiding the lateral deviation or shaking of the threaded block 302 during the movement, ensuring the linear motion accuracy of the threaded block 302, and further ensuring the smooth lifting and lowering of the lifting link 301 and the benchmark 102.

[0039] Furthermore, a U-shaped plate 308 is fixedly connected to the rear side of the fixing plate 304, and a plurality of mounting plates 309 are equidistantly connected to the surface of the U-shaped plate 308 away from the fixing plate 304. The plurality of mounting plates 309 are threadedly connected with mounting bolts 310 for fixing the device.

[0040] The design of the U-shaped plate 308 and multiple mounting plates 309 can significantly enhance the stability of the entire device, especially in environments with turbulent water flow or strong winds and waves. This design can ensure that the device will not easily loosen or fall off. The combined use of multiple mounting plates 309 and mounting bolts 310 makes on-site installation simpler and faster. The installation position can be adjusted according to actual conditions, and the device is fixed with mounting bolts 310 to ensure that it is firm and reliable. This design not only improves the installation stability and adaptability of the water level detection device, but also simplifies the installation and maintenance process, making the entire device more reliable and durable, which is very important for water level monitoring in water conservancy projects, and can ensure the accuracy of data and the long-term stability of the system.

[0041] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
