Description

Technical Field

[0001] This invention belongs to the field of water level detection technology, specifically relating to a water level monitoring device for hydropower station dams. Background Technology

[0002] A hydroelectric power station, also known as a hydropower plant, is a facility that converts the potential and kinetic energy of water into electrical energy. Water level monitoring includes factors such as riverbed changes, flow momentum, flow direction, flood diversion, ice conditions, aquatic plants, waves, wind direction, wind force, water surface undulation, water temperature, and other factors that affect water level changes. When necessary, the gradient of the water surface is also measured. During monitoring, the monitoring equipment generally directly detects the water level of the hydroelectric power station dam through water level sensors, which are fixed on both sides of the dam.

[0003] Existing hydropower station dam water level monitoring devices allow manual monitoring of the dam's water level by adjusting the angle of the monitoring cylinder, reducing interference from the external environment. However, the entire device cannot be easily installed on the riverbed or bank, resulting in reduced convenience. Sludge in the monitoring cylinder also tends to accumulate. Furthermore, multiple points cannot be measured simultaneously during use, leading to reduced accuracy of the measurement results. Summary of the Invention

[0004] To address the problems mentioned in the background section, this invention provides a hydropower station dam water level monitoring device, which features convenient installation, a flushing cylinder, and multi-point measurement to improve accuracy.

[0013] Compared with the prior art, the beneficial effects of the present invention are: 1. This invention is equipped with an installation mechanism. The installation base consists of a fixed plate and an inclined plate. The mounting base can be fixed to the ground by the pins. The extension plate can slide inside the perforated box. The extension plate can be fixed by the connection of bolts and nuts, so that the support box can be extended. When the extension plate extends, it will drive the U-shaped support plate to move. At the same time, the sliding rod slides in the hollow column, which can support the extension plate from below to improve stability. The anti-slip nails can prevent the installation base from slipping on the river mud. The support box can be fixed to the bank by the installation base and the pins, improving practicality. 2. This invention is equipped with a connecting mechanism. The long rod has multiple sets of internally threaded posts. The threaded cap is fixed to the outside of the first monitoring cylinder. The first and second monitoring cylinders have the same structure and function. The first monitoring cylinder can be fixed by screwing the threaded cap into the internally threaded post. In this way, when the water level is lowered, multiple monitoring cylinders can be driven to monitor together and obtain multiple monitoring results, thereby improving the monitoring accuracy. The threaded cap can block the unused internally threaded posts to prevent water plants from getting stuck in the threads. By connecting multiple monitoring cylinders through the internally threaded posts, multiple sets of results can be obtained, thereby improving the accuracy. 3. The present invention is equipped with a flushing mechanism. The water pump is connected to one side of the support box and communicates with the water tank. The water pump pressurizes the outside water into the water tank and then sprays it through the nozzles to the monitoring cylinder one and monitoring cylinder two, flushing the water plants and sludge on the outside of the two cylinders.

[0022] By adopting the above technical solution, the anti-slip nail 44 can prevent the mounting base 41 from slipping on the river mud.

[0023] In this embodiment, the drive motor 2 drives the threaded rod 10 to rotate, and at the same time drives the threaded seat 11 to move up and down, thereby changing the height of the monitoring cylinder 7, so that the measuring rod 8 can be inserted underwater for water level monitoring.

The connection of the bolt 433 and the nut 434 can fix the extension plate 432, so that the support box 1 can be extended. When the extension plate 432 is extended, it will drive the U-shaped support plate 437 to move. At the same time, the sliding rod 436 slides in the hollow column 435, which can support the extension plate 432 from below and improve stability. The anti-slip nail 44 can prevent the mounting base 41 from slipping on the river mud. Through the mounting base 41 and the pin 42, the support box 1 can be fixed to the bank, improving practicality.

In this way, when the detection water level is lowered, multiple monitoring cylinders can be driven to monitor together, obtain multiple monitoring results, and improve the monitoring accuracy.

[0025] Specifically, threaded caps 65 are provided on the upper and lower sides of the internal threaded post 62.

[0026] By adopting the above technical solution, the threaded cap 65 can block the unused internal threaded post 62, preventing water plants from getting stuck in the thread.

[0027] Specifically, the flushing mechanism 9 includes a water pump 91, a water tank 92 is provided on one side of the water pump 91, and a nozzle 93 is provided on one side of the water tank 92.

[0028] By adopting the above technical solution, the water pump 91 is connected to one side of the support box 1 and communicates with the water tank 92.

[0031] In this embodiment, the long rod 61 has multiple sets of internally threaded posts 62, and the threaded cap 63 is fixed to the outside of the first monitoring cylinder 64. The first monitoring cylinder 64 and the second monitoring cylinder 7 have the same structure and function. By screwing the first monitoring cylinder 64 into the internally threaded post 62 through the threaded cap 63, the first monitoring cylinder 64 can be fixed. In this way, when the detection water level drops, multiple monitoring cylinders can be driven to monitor together, and multiple monitoring results can be obtained, thus improving the monitoring accuracy. The threaded cap 65 can block the unused internally threaded posts 62 to prevent water plants from getting stuck in the threads. By connecting multiple monitoring cylinders through the internally threaded posts 62, multiple sets of results can be obtained, thus improving accuracy. The water pump 91 is connected to one side of the support box 1 and is connected to the water tank 92.

[0033] Working principle and usage of this invention: When in use, the drive motor 2 drives the threaded rod 10 to rotate, and simultaneously drives the threaded seat 11 to move up and down, thereby changing the height of the monitoring cylinder 7, allowing the measuring rod 8 to be inserted underwater for water level monitoring. The mounting base 41 consists of a fixed plate and an inclined plate. The pin 42 can fix the mounting base 41 to the ground. The extension plate 432 can slide within the perforated box 431. The connection of the bolt 433 and nut 434 can fix the extension plate 432, allowing the support box 1 to extend. When the extension plate 432 extends, it drives the U-shaped support plate 437 to move. Simultaneously, the sliding rod 436 slides within the hollow column 435, supporting the extension plate 432 from below, improving stability. The anti-slip pin 44 prevents the mounting base 41 from slipping on the river mud. Through the mounting base 41 and the pin 42, the support box 1 can be fixed to the bank, improving practicality. The long rod 61 has multiple sets of internal threads. The threaded post 62 and threaded cap 63 are fixed to the outside of the monitoring cylinder 64. The monitoring cylinder 64 and the monitoring cylinder 7 have the same structure and function. The monitoring cylinder 64 can be fixed by screwing the threaded cap 63 into the threaded post 62. In this way, when the detection water level drops, multiple monitoring cylinders can be driven to monitor together and obtain multiple monitoring results, thereby improving the monitoring accuracy. The threaded cap 65 can block the unused threaded post 62 to prevent water plants from getting stuck in the threads. By connecting multiple monitoring cylinders through the threaded post 62, multiple sets of results can be obtained, thereby improving accuracy. The water pump 91 is connected to one side of the support box 1 and is connected to the water tank 92. The water pump 91 pressurizes the outside water into the water tank 92 and then sprays it onto the monitoring cylinders 64 and 7 through the nozzle 93, cleaning the water plants and sludge on the outside of the two cylinders. The filter plate 94 can filter the water in the water tank 92 to prevent the nozzle 93 from getting clogged. By flushing the outside of the monitoring cylinders, sludge accumulation can be prevented.
