Technical Field

[0001] This utility model relates to the field of power station water level monitoring technology, specifically a hydropower station dam water level monitoring device. Background Technology

[0002] Hydropower stations, also known as hydroelectric power plants, are important facilities that convert the potential and kinetic energy of water into electrical energy. During the operation of hydropower stations, accurate and real-time monitoring of the dam water level is crucial. Real-time monitoring of the dam water level allows for timely and accurate access to water level information, which is of great significance for ensuring dam safety, optimizing power generation scheduling, preventing flood disasters, and rationally managing water resources.

[0003] For the installation of water level monitoring devices, in order to ensure the timely and accurate detection of water level parameters, the water level monitoring devices need to be installed in the water area near the lower part of the dam. Since the installation location is in the rear section of the reservoir, there are often aquatic plants such as waterweed and duckweed in the installation area. Due to the drifting characteristics of aquatic plants, they often block the water surface sensing area of ​​the monitoring device, affecting the normal operation of the monitoring device. Regular manual cleaning is required, which is very inconvenient. Therefore, a water level monitoring device for hydropower station dams is proposed. Utility Model Content

The installation mechanism is used for the working installation of the water level gauge. The installation mechanism includes a protective rod cylinder, an installation bracket, a lifting float, an installation end seat, and a protective end seat. The protective rod cylinder is supported and connected to the dam body through the installation bracket. Water communication holes are uniformly provided through the periphery of the protective rod cylinder.

The installation mechanism includes a protective rod cylinder 2, a mounting bracket 3, a lifting float 4, a mounting end seat 5, and a protective end seat 6.

[0029] As attached Figure 1 As shown, the protective rod cylinder 2 is a hollow cylindrical galvanized steel pipe with a waterproof paint layer. The protective rod cylinder 2 is supported and connected to the dam body by the mounting bracket 3. For details, see attached... Figure 6 As shown, the rear side seat of the mounting bracket 3 is fixedly installed to the support part near the water side of the dam body by bolts, serving as the installation support structure for the protective rod cylinder 2. To facilitate the clamping installation of the protective rod cylinder 2, a fastening clamp 8 is fixed to the front of the mounting bracket 3. The upper end of the protective rod cylinder 2 is inserted through the clamping part in the middle of the fastening clamp 8. Fastening bolts 9 are provided on the side of the fastening clamp 8. The protective rod cylinder 2 is fastened and fixed to the fastening clamp 8 by the fastening bolts 9. To facilitate the flow of water, the protective rod cylinder 2 is surrounded by... Water flow holes 10 are uniformly and evenly distributed throughout the protective rod cylinder 2. The protective rod cylinder 2 is installed on the lower sensing side of the water level gauge 1. Water flow holes 10 are evenly distributed throughout the protective rod cylinder 2. While ensuring water flow, a cylindrical base-type isolation and protection structure is formed at the lower part of the water level gauge 1 to block and isolate large-volume aquatic plants. This prevents the device from being blocked by large-volume aquatic plants and improves the stability of the device.

[0030] The water level gauge 1 is supported and installed on the upper part of the protective rod cylinder 2 via the mounting end bracket 5, as detailed in the attached document. Figure 4 As shown, the mounting end seat 5 is fixedly installed to the upper end cylinder of the protective rod cylinder 2 by threaded fastening. To facilitate the installation and connection of the water level gauge 1, a mounting screw hole 7 is provided through the middle of the mounting end seat 5. The detection end head of the lower part of the water level gauge 1 is fixedly installed to the inner side of the mounting screw hole 7 by thread. The protective end seat 6 is installed on the lower opening side of the protective rod cylinder 2 for filtering and protection of the lower part of the protective rod cylinder 2. Specifically, see attached... Figure 5 As shown, the protective end seat 6 is fixedly installed to the lower end cylinder of the protective rod cylinder 2 by thread fastening. In order to facilitate the flow of water, an inlet groove 12 is provided through the lower part of the protective end seat 6.

[0031] The middle part of the lifting float 4 is made of lightweight plastic, and the upper part is equipped with a floating part made of lightweight foam. The lifting float 4 is installed in the middle of the protective rod cylinder 2. For details, please refer to the attached document. Figure 2 As shown, to facilitate the connection and installation of the lifting float 4, an installation sleeve hole is provided in the middle of the lifting float 4. The lifting float 4 is slidably fitted into the middle of the protective rod cylinder 2 through the installation sleeve hole. In order to achieve the semi-submerged floating of the lifting float 4, a counterweight ring block 11 is provided at the lower part of the lifting float 4. The counterweight ring block 11 can be made of stainless steel and is ring-shaped. The counterweight ring block 11 is fixedly fitted and installed with the lower end seat of the lifting float 4. The lifting float 4 is installed with counterweight by the counterweight ring block 11. During operation, the lifting float 4 can float on the upper part of the water surface in a semi-submerged state. The floating isolation of the lifting float 4 can shield and isolate the water liquid communication hole 10 on the water surface side, which can prevent small aquatic plants from entering the water liquid communication hole 10. Combined with the external isolation of the protective rod cylinder 2, it can effectively solve the problem of the influence of aquatic plants on the operation of the monitoring device, save the cost of manual cleaning of aquatic plants and improve the working stability of the device.

[0032] Working principle or structural principle: During installation, the mounting bracket 3 is fixedly installed at the support on the water-near side of the dam body. Then, the upper end of the protective rod cylinder 2 is installed into the fastening clamp 8 at the end of the mounting bracket 3 through a through-plug.

Then, the upper wiring of the water level gauge 1 is connected and installed and its operation is tested to complete the installation work.

[0033] During operation, the liquid level inside the protective cylinder 2 is level with the external water surface through the connection between the liquid inlet channel 12 and the water communication hole 10. The ultrasonic sensor of the water level gauge 1 detects and collects the water level information in real time and transmits it to the data acquisition relay. During this process, floating aquatic plants and debris in the water area are blocked by the protective cylinder 2, preventing the device from being affected by large aquatic plants. At the same time, the downward action of the counterweight ring 11 is as shown in the attached figure. Figure 3 As shown, the lifting float 4 floats on the upper part of the water surface in a semi-submerged state. The floating isolation of the lifting float 4 can shield and isolate the water liquid communication hole 10 on the water surface side, which can prevent small duckweed from entering the water liquid communication hole 10. Combined with the external isolation of the protective rod cylinder 2, it can effectively solve the problem of the influence of aquatic plants on the operation of the monitoring device.
