[0042] The method of use and working principle of the device are as follows: first, when the entire device enters the water, the electric iris valve 52 installed on the top will control the opening through electronic signals, so as to accurately regulate the flow rate and pressure of the water entering the diversion vertical chamber 51, and under the setting of the two sets of inclined cone guide plates 53, the vortex in the water flow guided in can be reduced. At the same time, the design of large top diameter and small bottom diameter helps to accelerate the fluid and increase kinetic energy, so that the falling water flow can impact the inclined plate 55 of the first stress sensor group, so that the falling water flow impacts the inclined plate 55 of the first stress sensor group, and the dynamic potential energy of the water flow is converted into piezoelectric potential energy with the cooperation of the inclined plate 55 of the first stress sensor group, thereby improving the energy conversion efficiency. Then, with the cooperation of the diversion input chamber 56, the falling water flow is transported to the diversion input chamber 56.

When the water flows at a high speed to the inside of the impeller conversion chamber 15, the impeller is driven to convert the kinetic energy of the fluid into mechanical energy or electrical energy, and synchronously, in cooperation with the second stress sensor group plate, the impact water flow potential energy is converted into piezoelectric potential energy, and then in cooperation with the inclined plate 55 of the first stress sensor group, the output conversion optical fiber 25 is used to convert the water flow potential energy into piezoelectric potential energy. The formed piezoelectric potential energy is transmitted to the power energy storage converter 4, so that the power energy storage converter 4 stores the converted energy. Then, with the cooperation of the pressure-sensitive current conversion circuit 8, the energy stored in the power energy storage converter 4 is conveniently transmitted to the micro-generator 7, so that the micro-generator 7 further adjusts or improves the electric energy transmitted in the circuit, ensuring that the output voltage and current are stable and transmitted to the motor through the protection circuit. Then, with the cooperation of the underwater locator 6 and the signal transmitter, it is convenient to determine the precise position of the entire equipment underwater, so that when subsequent maintenance is needed, fixed-point maintenance operations can be carried out. At the same time, the signal transmitter can be used to send the status information, location data or fault damage information of the entire equipment to the surface control center or the satellite. Star, realize remote monitoring and communication adjustment, convert the direct current generated by the micro generator 7 into alternating current under the action of the inverter 16, and ensure the safety of the transmission circuit to prevent overload and short circuit with the cooperation of the protection line, and then stabilize the output line to ensure that the current converted by the inverter is stably output to the motor inside the pump body 24, and then transmitted to the reducer 11, so that the reducer 11 can reduce the high speed of the motor and increase the torque at the same time, so as to drive the whole pump body 24 more efficiently. Before the whole pump body 24 is operated, the reducer 11 and the guide vane body 13 form an oil cavity, and then inject it through the mechanical oil injection end 29. In order to achieve lubrication and cooling operation, the injected liquid level is higher than the top of the reducer 11 body.Then, the first oil-saving float 28 and the second oil-saving float 27 are respectively installed on the side of the reducer 11 and the side of the guide vane body 13, and the oil cavity volume is reduced by fully occupying the oil cavity space, thereby saving mechanical oil and greatly reducing the required amount of mechanical oil, but still achieving the effect of lubrication and cooling, which reduces the production cost on the one hand and reduces the weight of the entire pump and the operating load on the other hand. Afterwards, when the entire device is operating underwater, it is convenient to install the electric control rotating seat 23 on the bottom axial end of the disc body 1 to drive the obstacle avoidance sensor and the sound wave generator 22 to rotate, so that the obstacle avoidance sensor detects the surrounding obstacles to avoid collision, and the sound wave generator 22 is used to emit sound waves to drive underwater organisms and avoid damage to the entire device caused by collision of underwater organisms. Among them, the pressure relief end 17 is installed on the surface of the disc body 1, so that when entering the bottom of the water, the protective space composed of the disc body 1 and the protective cover 2 can reduce the pressure on the equipment. At the same time, the micro-sludge discharger 21 can be used to cooperate with the sludge discharge pipe 20 and the micro-sludge discharger 21 to discharge the sludge discharger 21 for a long time underwater. During operation, water and particles infiltrated into the gaps inside the disc body 1 and the protective cover 2 are extracted and discharged to ensure the service life of the entire device. Under the cooperation of the obstacle avoidance sensor, the axial rotation motor connection end 32 and the waterproof bearing member 33 are driven to adjust and rotate the first rotating main arm 34. Then, the first rotating main arm 34 and the second rotating main arm 36 are connected by the first rotating angle shaft joint 35 and the second rotating angle shaft joint 37, respectively, to form a multi-stage rotating structure, which greatly increases the adjustment angle range and flexibility. Secondly, the bottom slotted arm rod 390 is extended by the hydraulic support rod 39, so that the bottom slotted arm rod 390 drives the rotating support center of gravity foot 391 to rotate and adjust under the drive of the servo motor, and the support point can be dynamically adjusted according to the actual support work requirements under water, so as to achieve more precise positioning and balance control, and avoid the influence of the entry of underwater silt on the device. The operation of the positioning correction adjustment component 3 can be remotely operated, so that the positioning correction adjustment component 3 drives the entire device to walk on the surface of the underwater bed according to the operation requirements, thereby improving the usability of the entire device.
