The control device is used for determining whether the Stirling engine or the motor is selected as a power source based on the temperature value sent by the temperature sensor, wherein: when the temperature value exceeds a preset temperature threshold value, selecting the Stirling engine as a power source, and controlling the power transmission device to be connected with the Stirling engine so as to drive the impeller through the Stirling engine; and when the temperature value is continuously lower than the preset temperature threshold value within a preset time (for example, 1 minute), selecting the motor as a power source, controlling the power transmission device to be connected with the motor, and controlling the energy storage device to supply power to the motor so as to drive the impeller through the motor.
That is, in the embodiment of the present invention, the control device is configured to determine whether the photothermal level of sunlight satisfies the requirement for the start of the stirling machine based on the temperature detected by the temperature sensor. When the sunlight is sufficient and the temperature can enable the Stirling engine to rotate, the power transmission device is controlled to be connected with the Stirling engine, and the Stirling engine is normally started to drive the fan blades to rotate for oxygenation; when sunshine is insufficient, the temperature is too low to enable the Stirling engine to be started, the control device starts an electric signal to control the power transmission device to be disconnected with the Stirling engine and be connected with the motor, and the electric energy stored in the electric storage device drives the three-phase motor to rotate to drive the fan blades to rotate to increase oxygen.

and P is the instantaneous power of the wind power generation device, pi is the rated power of the ith electric device, u is the total number of the electric devices, the electric quantity of the energy storage device is lower than a first threshold value, and the temperature value exceeds a preset temperature threshold value, then the power transmission device is controlled to be disconnected with the motor and connected with the Stirling engine. First, theA threshold value may be set according to the actual situation, for example, 70% of the full charge of the energy storage device may be set.
(2) When the current working state is detected to be the driving of the stirling engine, if the electric quantity stored by the wind power generation device to the energy storage device is greater than the electric power supply quantity required by the energy storage device to all the electric devices of the oxygen increasing equipment within a preset time period delta t, for example, within 10 minutes, that is,

That is, the technical effects of (1) and (2) are that the same power source is always used under the most appropriate conditions.
In the embodiment of the invention, the floating body 1 is used for bearing the weight of the water aerator and separating the aerator device from the water surface, and the specific structure of the floating body 1 can be set by using the balance principle of buoyancy and gravity, namely, the floating body is set according to the condition that the weight of water drained by the floating body is equal to the weight of the aerator. In one example, the floating body 1 may be provided to include 4 floating bodies connected by bolts for convenience of manufacture, transportation and management.

(2) compared with the method that the motor is driven to operate by utilizing solar power generation as a power source, solar photo-heat is directly converted into mechanical energy from heat energy through the Stirling engine, the energy utilization rate is improved by about 2.5 times compared with that of the mechanical energy, and the loss in two energy conversion processes of converting the solar energy into the electric energy and then converting the electric energy into the mechanical energy is greatly reduced, so that the energy utilization efficiency is greatly improved;
(3) compared with the diesel engine used as a power source to drive the aerator to work, the Stirling engine belongs to a low-temperature engine, renewable clean energy such as solar energy is used as a heating source, the use of fossil energy such as diesel oil is reduced, and the pollution to the environment is reduced. The Stirling engine is an external combustion engine, so that the problem that a traditional internal combustion engine works by virtue of detonation during working can be solved when the Stirling engine works, efficient working can be realized, and the working noise is low and the pollution is small.
Further, in the embodiment of the present invention, the solar heat collector 4 may include a focusing fresnel lens, and a horizontal rotation mechanism and a vertical swing mechanism connected to the focusing fresnel lens.

The vertical swing mechanism is used for rotating the focusing Fresnel lens in the vertical direction, namely swinging up and down along the supporting point of the focusing Fresnel lens so as to adjust the position of the lens in the vertical direction. Through adjustment of the horizontal rotating mechanism and the vertical swinging mechanism, the focusing Fresnel lens can rotate around sunlight, so that the sunlight can be irradiated on the focusing Fresnel lens in real time (at any moment), and a focusing point is always positioned on an outer cavity of the Stirling engine. The horizontal rotation mechanism and the vertical swing mechanism may be any structures driven by a stepping motor in the prior art, as long as the focusing fresnel lens can be rotated in the horizontal direction and the vertical direction.

In the embodiment of the invention, the sunlight tracking is carried out by adopting a photoelectric tracking mode, so that the error is small and the precision is high. In addition, the position of the focusing Fresnel lens can be adjusted in the horizontal direction and the vertical direction simultaneously through the horizontal rotating mechanism and the vertical swinging mechanism, and the focusing Fresnel lens is guaranteed to always position the focus on the Stirling engine heating cylinder.

When the moving mechanism 714 drives the power transmission connecting structure to move forward, the input connecting end 708 of the power transmission connecting structure is connected with the output connecting end 713 of the second power input structure, and the output connecting end 709 of the power transmission connecting structure is connected with the second input connecting end 711 of the power output structure, so that the power of the electric motor 6 is transmitted to the impeller, and the alternate transmission of the power of the stirling engine 3 and the electric motor 6 can be realized.

In order to add extra weight to the power input shaft of the Stirling engine and the three-phase asynchronous motor because the rotating speed ratio of the large belt wheel is low, in the embodiment of the invention, the large belt wheel arranged on the power input shaft connected with the Stirling engine and the three-phase asynchronous motor is selected from a spoke type belt wheel, and the small belt wheels on the Stirling engine and the three-phase asynchronous motor can be web type belt wheels. The large belt wheel and the small belt wheel are connected through a transmission belt 715. In one example, the transport belt 715 may be a V-belt. Preferably, the type of V-belt may be an a-belt.

The first input connection end 712 and the second input connection end 711 may be sleeved on the power output shaft 710.
Further, the output connecting ends of the first power input structure and the second power input structure may be bevel gears. Two input connecting ends of the power output structure are both bevel gears. The input connection end 708 and the output connection end 709 of the power transmission connection structure may be bevel gears that mesh with the bevel gears of the power input structure and the power output structure, respectively. Preferably, the bevel gear may be a straight bevel gear.
Furthermore, in the embodiment of the invention, all the shafts and the straight bevel gears, the shafts and the V-belt pulleys are positioned by selecting common flat key connection.
Specifically, in the embodiment of the present invention, when the control device determines that the stirling engine is required to drive the impeller, the control device sends a corresponding control signal to the moving mechanism 714, and the stepping motor of the moving mechanism is started to drive the power transmission connection structure to move backward, so that the two bevel gears of the power transmission connection structure are respectively engaged with the bevel gear of the first power input structure and the upper bevel gear of the power output structure, thereby forming a power transmission path of the stirling engine 3, that is, the power of the stirling engine 3 is transmitted to the impeller through the first power input structure, the power transmission connection structure and the power output structure in sequence, so as to drive the impeller to rotate to perform an oxygen increasing operation. When it is determined that the three-phase asynchronous motor is required to drive the impeller, the control device sends a corresponding control signal to the moving mechanism 714, and the stepping motor of the moving mechanism is started to drive the power transmission connecting structure to move forward, so that the two bevel gears of the power transmission connecting structure are respectively meshed with the bevel gear of the second power input structure and the lower bevel gear of the power output structure, and a power transmission path of the motor 6 is formed, that is, the power of the motor 6 is transmitted to the impeller sequentially through the second power input structure, the power transmission connecting structure and the power output structure, so that the impeller is driven to rotate to perform oxygen increasing operation. That is, the power transmission device of the present invention can alternately transmit the power of the stirling engine and the electric motor.
The wind-solar complementary type oxygenation equipment provided by the embodiment of the invention can be applied to pool oxygenation of scenic spots or gardens, and preferably can be applied to oxygenation of aquaculture areas.
To sum up, the wind-solar complementary type oxygenation equipment provided by the embodiment of the invention can realize two oxygenation working modes: one is that the Stirling engine is heated by the solar heat collector to work, so that the impeller is driven by the power transmission device to complete the oxygen increasing work on the water body, namely, the solar energy is used for oxygen increasing work; one is that the electric energy generated by the wind power generation device drives the three-phase asynchronous motor to work, thereby driving the impeller to complete the oxygen increasing work of the water body through the power transmission device, namely, the wind energy is utilized to carry out the oxygen increasing work. When sunlight is sufficient, the Stirling engine can operate to drive the aerator to work, and electricity generated by the wind power generation device is stored in the energy storage device to serve as a storage power supply; when the sunlight is insufficient and the wind power is sufficient, the electric energy generated by the wind power generation device directly drives the motor to drive the aerator to work; when sunlight and wind power are insufficient, the electric energy stored in the battery pack can still drive the motor to drive the aerator to work within a period of time, so that the solar energy and wind energy clean and renewable energy are used as power sources, the traditional fossil energy is saved, and the solar energy aerator has the advantages of cleanness, no pollution, economy, environmental protection and the like. Compared with the power supply by adopting a power grid, the power supply device saves the electric energy of the power grid, avoids the investment of long-distance power transmission and distribution, saves the electric power cost for farmers, increases the flexibility of equipment application, and improves the safety of the equipment. And two renewable energy sources of solar energy and wind energy are used, so that the oxygen supply problem under multi-climate conditions is solved, the defect that the oxygen supply depends on electric power as the energy source is overcome, and the potential safety hazard existing in the working process of the traditional aerator is avoided. In addition, solar energy is utilized to directly convert heat energy into mechanical energy through the Stirling engine, and the energy utilization rate is greatly improved.
