Description

Technical Field

[0001] This utility model relates to the field of water conservancy engineering technology, specifically to a water quality monitoring device for water conservancy dams. Background Technology

[0002] In modern water resource management and ecological environmental protection, water conservancy dams, as important water conservancy engineering facilities, directly affect the water quality of the surrounding water bodies, impacting water supply security, ecological balance, and the health of downstream residents. Therefore, real-time, continuous, and accurate water quality monitoring of dam water areas is of great significance.

[0003] However, when existing water quality monitoring equipment is applied to complex water environments such as water conservancy dams, the water quality monitoring instruments are immersed in water for a long time, making them susceptible to contamination by algae, silt, and microorganisms. This leads to decreased sensor sensitivity, increased measurement errors, and even malfunctions, seriously affecting the accuracy and reliability of the data. In order to ensure monitoring quality, manual cleaning is required regularly, which is not only inefficient and costly, but also difficult to implement during flood season or in severe weather, posing safety hazards.

[0004] This necessitates a new type of water quality monitoring equipment for water conservancy dams. Utility Model Content

[0005] The technical problem to be solved by this invention is that water quality monitoring equipment for water conservancy dams is easily damaged by long-term immersion and is difficult to clean.

[0006] To solve the above-mentioned technical problems, the technical solution provided by this utility model is as follows: a water quality monitoring device for a water conservancy dam includes a floating plate, a solar energy storage mechanism, a monitoring mechanism, and a cleaning mechanism;

[0007] An equipment box is installed through the center of the floating plate. Inside the equipment box, a power supply processing unit is separated by a partition plate. After the solar energy storage mechanism is installed on the floating plate, it is connected to the power supply processing unit in the equipment box.

[0008] The monitoring system includes a water quality monitor. After the water quality monitor is installed inside the net cylinder, it is connected to the power supply unit via a connecting cable. The equipment box is pushed out or retracted by a lifting mechanism. After the lifting mechanism pushes out the net cylinder, the net cylinder is submerged in the dam.

[0009] The cleaning mechanism is located inside the equipment box and surrounds the screen cylinder. After the screen cylinder is retracted into the equipment box via a lifting mechanism, the cleaning mechanism rinses the water quality monitoring instrument inside the screen cylinder.

[0010] As an improvement, the solar energy storage mechanism includes solar panels; after the solar panels are mounted above the floating plate and equipment box, they are connected to the power supply processing unit via an inverter.

[0011] As an improvement, the lifting mechanism includes a hydraulic telescopic rod, which is provided in pairs. One end of the hydraulic telescopic rod is fixedly connected to the bottom surface of the partition plate, and the other end is connected to an L-shaped rod that is slidably connected to the inner wall of the equipment box. The end of the L-shaped rod is fixedly connected to the top surface of the mesh cylinder.

[0012] As an improvement, the cleaning mechanism includes a ring sleeve, a sprayer, and a water pumping and purification mechanism;

[0013] After the annular sleeve is fixedly installed at the bottom of the equipment box, the central through hole is connected to the slot on the bottom surface of the equipment box for the mesh cylinder to pass through. A water cavity is opened inside the annular sleeve. After water enters the water cavity through the water pumping and purification mechanism, it is sprayed into the mesh cylinder through multiple sprayers on the inner wall of the annular sleeve.

[0014] As an improvement, the water purification mechanism includes a water pump and an annular filter element;

[0015] The water pump is fixedly installed at the bottom of the outer wall on both sides of the equipment box. The water outlet is connected to the water chamber, and an annular filter element is placed in the water chamber. After the water enters the water chamber through the water pump, it is filtered by the annular filter element and then delivered to each sprayer.

[0016] As an improvement, the bottom of the equipment box is open and sealed with a cover plate, with slots made on the cover plate.

[0017] The advantages of this utility model compared with the prior art are as follows:

[0018] 1. The lifting mechanism can control the water quality monitor to submerge and retract, protecting it when not in use and reducing the risk of damage;

[0019] 2. The net can prevent the water quality monitoring instrument from being directly submerged in the dam, reducing the impact of surrounding impurities on the water quality monitoring instrument;

[0020] 3. After the equipment is retrieved, the cleaning mechanism automatically sprays and washes the screen and sensors to effectively remove deposits and ensure monitoring accuracy. Attached Figure Description

[0031] Activate the hydraulic telescopic rod 7, which pushes the L-shaped rod 8 to move the net cylinder 5 downward, allowing the water quality monitor 4 to be submerged to a predetermined depth. The water quality monitor 4 then begins collecting parameters such as water temperature, pH value, dissolved oxygen, turbidity, and conductivity. The data is transmitted to the power supply processing unit 3 via a connecting cable, processed, and then uploaded to the monitoring center via a wireless module. After monitoring is completed, the hydraulic telescopic rod 7 is retracted, lifting the net cylinder 5 and the water quality monitor 4 into the equipment box 2.
