Description

Technical Field

[0001] This utility model belongs to the field of water level detection technology, and specifically relates to an automatic water level height detection device based on solar power. Background Technology

[0002] In maintaining the normal operation of water conservancy and hydropower projects, water level is an important monitoring indicator. It can reflect the water storage capacity, flood peak regulation capacity, and so on of the water conservancy and hydropower projects. Real-time monitoring of water level can reflect the water storage situation of water conservancy projects in real time. On the one hand, it is beneficial to the daily management work of water conservancy project managers, and on the other hand, it can provide emergency reminders to managers of water level changes during rainfall.

[0003] Traditional water level detection methods rely primarily on simple detection structures or basic electronic sensing technologies. However, in practical applications, these methods suffer from insufficient accuracy, low reliability, high maintenance costs, and poor environmental adaptability, making them unsuitable for the detection needs of modern intelligent systems and complex environments. For example, float-type water level detection uses a float that rises and falls with the water level to trigger a corresponding switch or to indicate a specific scale point, thus acquiring water level information. However, this method is easily affected by liquid viscosity, sedimentation, and equipment wear. Another example is pressure-type sensors, which use piezoresistive or piezoelectric effects to calculate water level height by detecting the hydrostatic pressure of the liquid. These sensors have strict requirements for installation location, require vertical calibration, and are susceptible to interference from temperature fluctuations and changes in liquid density. Measurement errors increase significantly in dynamic liquid surfaces or liquids containing air bubbles.

[0004] In recent years, non-contact detection technologies (such as ultrasonic, radar, and laser ranging) have become increasingly popular. Although they avoid direct contact with liquids, some technical problems still exist, such as installation limitations (requiring vertical detection space, making deployment difficult, susceptibility to harsh environments, and high energy consumption). Therefore, to solve these technical problems, it is urgent to design an automatic water level height detection device that can be powered and ensures the stability of installation and the detection environment.

[0025] Example

[0026] like Figures 1 to 2 As shown, an automatic water level detection device based on solar power includes a mounting bracket 100, on which a solar power supply mechanism 200, a display screen 300 and a water level detection mechanism 400 are electrically connected to each other. The solar power supply mechanism 200 provides stable power to the display screen 300 and the water level detection mechanism 400.

[0027] Preferably, the water level detection mechanism 400 includes a detection part 410 and a mounting part 420. The detection part 410 is installed in the mounting part 420, which provides stable installation conditions and a stable detection environment for the detection part 410, preventing external factors (such as wind, rain, temperature and humidity, electromagnetic radiation, obstacles, etc.) from interfering with the detection process. One end of the mounting part 420 is mounted on the mounting bracket 100. Notably, one end of the mounting part 420 is mounted on the mounting bracket 100 via a connecting mounting handle 430. The other end is vertically inserted and fixed to the bottom of the water area to be tested. Water flows in from the insertion end of the mounting part 420, and the water surface flowing into the mounting part 420 is level with the water surface of the external water area to be tested. The detection part 410 detects the height of the flowing water and transmits the detected data to the display screen 300 in the form of an electrical signal. The display screen 300 processes the data and displays the processed water level height detection data in digital form so that the operator can monitor the water level in real time.

[0028] It is worth mentioning that the detection unit 410 is a radar probe, which is electrically connected to the display screen 300. The radar probe feeds back the detected electrical signals to the display screen 300, which processes and displays them.

[0029] In some preferred embodiments, the mounting part 420 includes a mounting water pipe 421 and a float 422. The insertion end of the mounting water pipe 421 is provided with a water inlet 423, and a filter screen 424 is provided at the water inlet 423. Several vent holes 425 are evenly distributed on the mounting water pipe 421. The float 422 is disposed inside the mounting water pipe 421. The mounting water pipe 421 is vertically inserted into the bottom of the water body to be tested. The water from the water source to be tested flows into the pipe body of the mounting water pipe 421 through the water inlet 423 and the filter screen 424. The vent holes 425 ensure that the pressure inside the mounting water pipe 421 is equal to the pressure of the external environment, ensuring that the water level inside the mounting water pipe 421 is flush with the water level of the external water body to be tested. The float 422 floats inside the mounting water pipe 421 under its own buoyancy. It is worth mentioning that... To prevent the float 422 from getting stuck inside the installation water pipe 421, the diameter of the float 422 is smaller than the diameter of the installation water pipe 421. The filter screen 424 is designed to further filter the water entering the installation water pipe 421, preventing foam or impurities from entering the installation water pipe 421 and causing the test liquid to stick and affect the test results. Impurities entering the installation water pipe 421 can cause blockage inside the installation water pipe 421, affecting the test values ​​and test results.

[0030] In some preferred embodiments, the mounting bracket 100 includes a mounting base 110, a solar mounting rod 120, a display screen mounting rod 130, a connecting sleeve 140, a rotating mounting base 150, and a hinge support 160. The display screen mounting rod 130 is mounted on the mounting base 110, and the solar mounting rod 120 is mounted on the display screen mounting rod 130 via the connecting sleeve 140. The solar power supply mechanism 200 is rotatably connected to the end of the solar mounting rod 120 via the hinge support 160. The solar power supply mechanism 200 can adjust the angle of the received light source via the hinge support 160, and the solar power supply mechanism 200 can adjust the direction of the received light source via the connecting sleeve 140. The display screen 300 is rotatably connected to the display screen mounting rod 130 via the rotating mounting base 150. The solar power supply mechanism 200 is a solar panel. The solar power supply mechanism 200 is electrically connected to the radar probe and the display screen 300 respectively, providing stable power to the radar probe and the display screen 300. The solar power supply mechanism 200 is a device that can directly convert sunlight into electrical energy. Its core is the photovoltaic effect. The solar power supply mechanism 200 is existing technology, and its working principle and composition will not be described in detail here.

[0031] In some preferred embodiments, since the automatic water level detection device is installed outdoors, the mounting bracket 100 is susceptible to corrosion from rain or corrosive water in the installation environment, affecting its service life. Therefore, the mounting bracket 100 is entirely bluing. Bluing is a surface treatment process for steel parts to prevent corrosion. Its principle is to generate a dense oxide layer of a certain thickness and strength on the steel surface, mainly composed of magnetite (Fe3O4). Ordinary steel is prone to rust; bluing the surface of steel parts can greatly enhance corrosion resistance and extend service life.

[0032] When detecting water level, the detection unit 410 (radar probe) is installed at a certain position near the upper end of the installation water pipe 421 and the data is recorded. It is worth mentioning that the installation water pipe 421 is always fixedly inserted at the bottom of the water area to be detected. The detection unit 410 and the installation water pipe 421 are detachably connected, and the installation bracket 100 is stably connected to the installation water pipe 421 through the connecting installation handle 430. Water in the water area to be tested flows in through the water inlet 423, and the float 422 floats under the action of the water. The detection unit 410 detects the water level in the installation water pipe 421. Let the transmission distance of the emitted wave from the detection unit 410 to the float 422 be H1, and let the height of the installation water pipe 421 be H2. The diameter of the float 422 is negligible. Therefore, the water level of the water area to be tested is H = H2 - H1. The obtained water level height is processed by a computer and displayed on the screen 300. This active water level height detection device is powered by the solar energy supply unit 200 during operation.

[0033] In summary, this utility model provides an automatic water level detection device based on solar power. This device provides a stable installation structure for the detection unit and utilizes solar energy for stable power supply. The device has a simple structure and can detect water level in a timely and accurate manner. The installation unit provides stable installation conditions and a stable detection environment for the detection unit, avoiding interference from external factors (such as wind, rain, temperature and humidity, electromagnetic radiation, obstacles, etc.) on the detection process.
