Description

TECHNICAL FIELD

[0001] The utility model relates to water quality detection device, especially a water surface solar energy water quality detection device. BACKGROUND

[0002] Water quality detection device is used for detecting the kind of pollutant in water body, the concentration and change trend of various pollutants, and the instrument of evaluating water quality condition. It can be used for monitoring rivers, rivers, lakes, seas and various industrial drainage.

[0003] In order to accurately detect water quality, it is usually necessary to set multiple water quality detection devices at different positions of the water body, for example, multiple water quality detection devices are distributed and arranged at the center and edge positions of the water body. However, since the center of the water body is usually far away from the water bank, the power supply problem of the water quality detection device on the water surface of the water body center becomes extremely difficult.

[0004] In recent years, with the development of solar energy technology, some people have proposed a scheme of using solar energy to power the water surface water quality detection device. The charging principle of solar cell is to convert solar energy into electric energy through solar cell panel. The solar cell panel is composed of multiple component units, and each unit contains a thin film semiconductor cell. When sunlight shines on the film, photons will be absorbed and excite electrons in the semiconductor, making them jump to a higher energy level. These excited electrons will move inside the semiconductor until they are collected on the electrode to form an electric current.

[0005] In the prior art, CN220430425U discloses a solar energy water surface intelligent float, which comprises a floating box, a rotating assembly, four photovoltaic assemblies, an auxiliary assembly and an alarm assembly. The rotating assembly is arranged on the top of the floating box, the photovoltaic assemblies are arranged on the outer side of the rotating assembly, the auxiliary assembly is arranged between the floating box and the rotating assembly, and the alarm assembly is arranged at the top end of the rotating assembly. However, in this technology, the motor, battery and other mechanical and electrical parts are directly placed in the floating box without any protection treatment. The motor, battery and other parts are connected with the outside through the openings on the floating box. These openings will allow water vapor to enter the inside of the floating box, which will cause corrosion or short circuit of the mechanical and electrical parts in the floating box.

[0006] In the prior art, CN117208150A discloses a water unmanned environment monitoring device for setting in natural water body to carry out automatic cruising water quality monitoring, comprising a floating box and a connecting frame, the floating box is arranged in the middle of the connecting frame, one end of the connecting frame is connected with a detection box sunk below the water surface, the other end is connected with a solar panel on the floating box, and the solar panel is connected with a solar module in the detection box to provide electric energy; the detection box also has a cavity, a detection module is arranged at the bottom of the cavity, the detection module has a plurality of water quality detection sensors extending into the cavity and having detection ends at the bottom of the cavity; the detection box also has a wireless module and a gnss positioning module, the control part in the solar module is connected with the water quality detection sensor to obtain monitoring data, and the monitoring data is sent to the back-end server through the wireless module for feedback, and the back-end server determines the real-time position of the corresponding monitoring device according to the data of the gnss positioning module. In this technology, the detection module is directly submerged below the water surface, which puts higher requirements on the waterproofness of the detection module, and the cost is greatly increased.

[0007] The current solar water quality detection device cannot be used near the water surface. The main reason is that the waterproof requirement of the circuit part of the solar cell charging system does not support the operation near the water surface, and most of the common products on the market of the same type cannot reach the waterproof level that can work near the water surface, and cannot be used in environments with high waterproof level requirements. Practical new type
