Description

Technical Field

[0001] This invention relates to the field of marine hydrological monitoring technology, specifically to a hydrological monitoring sensor. Background Technology

[0002] Hydrological monitoring is a crucial foundation for understanding water resource dynamics, ensuring flood control safety, and supporting ecological protection. In aquatic environments such as rivers, lakes, reservoirs, and oceans, it is necessary to obtain key data such as water level, flow rate, water temperature, and water quality in real time.

[0003] Hydrological monitoring sensors typically consist of a sensing module, a data processing module, a communication module, a power supply module, and a protective housing. The sensing module contains various types of sensitive elements, such as pressure sensors for measuring water levels, ultrasonic sensors for non-contact liquid level measurement, and electrode sensors for detecting water quality parameters. The data processing module amplifies, filters, performs analog-to-digital conversion, and performs algorithm calculations on the raw signals collected by the sensing module, converting them into standard data. The communication module supports wireless communication methods such as 4G / 5G, or wired communication methods such as fiber optics and RS485, enabling remote data transmission. The power supply module uses a combination of solar panels and lithium batteries to ensure long-term stable operation. The protective housing is made of high-strength, corrosion-resistant materials and has an IP68 protection rating, making it suitable for harsh environments such as underwater, humid, and direct sunlight.

[0004] However, the above-mentioned devices have obvious shortcomings in use. Traditional hydrological monitoring sensors mostly use a single principle to detect turbidity, such as relying solely on infrared light scattering, which cannot distinguish between suspended particulate matter and organic matter. They also have large detection errors for special substances such as colloids and algae in water bodies, resulting in low measurement accuracy and making it difficult to meet the needs of high-precision monitoring. In view of this, we propose a hydrological monitoring sensor. Summary of the Invention

[0012] In a further embodiment, the infrared light sensor includes an infrared light-emitting diode and an infrared photosensitive receiving diode. The infrared light-emitting diode is used to emit infrared light with a wavelength of 850nm. The infrared photosensitive receiving diode is set at a 90° angle to the infrared light-emitting diode and is used to receive the infrared light scattered by suspended particles in the water and convert it into an electrical signal.

[0013] In a further embodiment, the ultraviolet light sensor includes an ultraviolet light-emitting device and an ultraviolet light-sensitive receiver. The ultraviolet light-emitting device is used to emit ultraviolet light with a wavelength of 254 nm. The ultraviolet light-sensitive receiver is set at a 90° angle to the ultraviolet light-emitting device and is used to receive ultraviolet light scattered by organic matter or colloidal particles in the water body, as well as to detect the attenuation of ultraviolet light in the water body.

[0014] In a further embodiment, a cleaning assembly is provided on the weighted disc, one end of an elastic square rod is fixedly installed on the weighted disc, a scraper is fixedly installed on the other end of the elastic square rod, a cavity is opened inside the elastic square rod, and a spring plate is fixedly installed inside the elastic square rod.

[0015] In a further embodiment, multiple sets of the elastic square rod, scraper, cavity, and spring plate are provided, with the spring plate disposed inside the cavity and the scraper attached to the surface of the glass ball.

[0016] In a further embodiment, a flow velocity component is provided on the thick pipe. The flow velocity component includes a mounting bracket. The mounting bracket is fixedly installed on the thick pipe. A flow velocity sensor is fixedly installed on the mounting bracket. A round rod is rotatably installed on the flow velocity sensor.

[0017] In a further embodiment, the testing cabin is equipped with an auxiliary component, which includes an opening. An opening is formed on the sealing plate. An installation plate is fixedly installed on the testing cabin. A water pumping device is fixedly installed on the installation plate. One end of the water pumping pipe is fixedly installed at the water pumping end, and a drain pipe is fixedly installed at the water outlet end of the water pumping device.

[0019] In a further embodiment, the exhaust vent is located above the testing chamber, and the drying device is located above the exhaust vent.

[0020] Compared with the prior art, the present invention provides a hydrological monitoring sensor with the following advantages:

[0021] 1. This hydrological monitoring sensor, in order to monitor turbidity changes in real time, is equipped with a turbidity component. This component, in conjunction with a hydraulic device, drives a sliding plate to slide up and down in the detection chamber, thereby immersing a hollow ball and a glass ball in water. Multiple water inlets on the surface of the hollow ball ensure smooth water flow, and a weight plate keeps the detection unit in a vertical position. The turbidity sensor integrates infrared and ultraviolet light detection modules. The infrared light-emitting diode and the photosensitive receiving diode are designed at a 90° angle. Turbidity is calculated by the intensity of light scattered by particulate matter, while the ultraviolet light device monitors the concentration of organic matter by the attenuation.

[0022] 2. To prevent detection errors caused by dirt obstruction, this hydrological monitoring sensor is equipped with a cleaning component. This component, together with multiple sets of elastic square rods, drives a scraper to adhere to the surface of the glass bulb. The elastic deformation of the spring plate in the cavity causes the scraper to continuously remove attached algae, silt, and other pollutants. The arc-shaped design of the scraper ensures that there are no dead corners in cleaning, keeping the surface of the glass bulb clean at all times and avoiding detection errors caused by dirt obstruction.

[0023] 3. In order to measure the flow velocity at different radial positions, this hydrological monitoring sensor is equipped with a flow velocity component. This component, together with multiple sets of turbine blades, rotates with the water flow. The circular rod drives the magnetoelectric induction device of the flow velocity sensor to convert the rotation speed into a flow velocity signal. The rigid connection between the mounting bracket and the thick pipe ensures that the turbine shaft is parallel to the water flow direction. The annular distribution of multiple sets of flow velocity sensors can simultaneously measure the flow velocity at different radial positions and generate three-dimensional flow velocity distribution data.

[0024] 4. To ensure the long-term stable operation of the hydrological monitoring sensor, an auxiliary component is installed. When the detection work is completed, this component, together with the water pumping device, draws out the liquid in the detection chamber through the water pumping pipe and discharges it through the drain pipe, so that there is no excessive liquid in the detection chamber when it is not in operation, avoiding liquid residue from affecting the accuracy of the sensor. At the same time, a drying device is activated after the detection unit is recycled, circulating hot air through the exhaust vent to keep the detection chamber dry and prevent electronic components from being damaged by moisture.

[0046] In this embodiment, the detection chamber 51 fixed at the bottom of the detection cabin 2 is the key space for turbidity detection. The internal hydraulic device 52 can drive the sliding plate 54 to slide up and down inside the detection chamber 51. When the monitoring work begins, the hydraulic device 52 is activated, pushing the sliding plate 54 to slide downwards inside the detection chamber 51.

Ensure the detection unit is vertical. At this point, the turbidity component 5 starts working. The infrared light sensor 516 and the ultraviolet light sensor 517 of the turbidity sensor 515 detect the turbidity and organic matter concentration of the water, respectively. The infrared light-emitting diode of the infrared light sensor 516 emits infrared light with a wavelength of 850nm, which is used to receive the infrared light scattered by suspended particles in the water and convert it into an electrical signal.
