[0042] Working principle:

[0043] The solar power generation module 2 is used to convert light energy into electrical energy. At the same time, based on the structure of the pendulum damper 13, the composite independent layer nano-friction power generation component and the electromagnetic power generation component convert wave energy into electrical energy, and store the electrical energy in the battery. When the device is under a certain light intensity, the solar power generation component based on the solar azimuth and altitude angle tracker 9 will track the sun's position in real time, so that the solar power generation module 2 and the angle of the incident sun light are perpendicular, and the utilization rate of solar energy is improved. At the same time, the waves impact the fixed shell 17, driving the pendulum damper 13 to shake continuously, realizing the TENG-EMG composite collection of wave energy for power generation, and connecting the battery to power supply through the parallel circuit of solar energy and TENG-EMG, so that the three cooperate to power the battery for powering the load; when the device faces continuous cloudy days or nights, the device mainly uses TENG-EMG to power the battery, so that TENG-EMG and the battery can jointly power the load.

[0044] Specifically, when the solar power generation module 2 is exposed to sunlight, the light energy excites the movement of electrons to generate electrical energy; when the device is impacted by waves, the pendulum damper 13 structure inside the device will reciprocate, and the negative friction electric material of the nano friction power generation module 12 attached to the pendulum damper 13 will undergo relative friction movement with the positive friction electric material coated on the inside of the large disk to generate electrical energy; at the same time, the permanent magnet 20 fixed inside the small disk of the pendulum damper 13 will cut the magnetic lines of force generated by the electromagnetic coil 19 attached to the top end of the fixed shell 17 as the pendulum damper 13 structure moves, generating electrical energy.

[0045] At the same time, the control module 23 of the present invention adopts a built-in single-chip control, and adds 4G module, GPS module and other modules, and an MCU controls the above modules. The single-chip central control system adds a 4G module and uses the mqtt protocol to communicate with the Alibaba Cloud Internet of Things platform. Through the Internet of Things technology, the water quality information, longitude and latitude information, and working conditions in the system are fully visible, ensuring the visual experience during use.

[0046] In summary, the present invention realizes autonomous power supply of the buoy through the novel design of the fixed shell 17 and is equipped with diversified power generation mode equipment, thereby providing continuous and stable energy for the electrical load. By simultaneously collecting three clean energy sources, namely solar energy, electromagnetic energy and friction nano energy, the equipment master controller is able to continuously and stably control the normal operation of the buoy's electronic components. When the working signal is received, the cable reel 6 rotates, so that the water quality detection sensor 8 can perform water quality detection at different depths. The collected water quality data is transmitted to the control module 23 through the connecting cable 7, and is sent to the user terminal after multiple layers of data processing and protection. In this way, the automation, unmanned and intelligent water quality detection is realized, providing users with a convenient operating experience.
