Detailed Description
To facilitate an understanding of the present application, the present application will now be described more fully with reference to the accompanying drawings. Preferred embodiments of the present application are illustrated in the accompanying drawings. This application may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete.
Referring to fig. 1, a water current power generation system includes: the water wheel power generation device 10 is connected with the energy storage device 20 and the switch control device 30, the energy storage device 20 is connected with the switch control device 30, the switch control device 30 is used for connecting a load, and the water wheel power generation device 10 is used for generating power according to input water flow and outputting the generated electric energy; the energy storage device 20 is used for storing the electric energy output by the water wheel power generation device 10; the switch control device 30 is configured to obtain the electric energy data stored in the energy storage device 20 when the water turbine generator 10 generates power according to the input water flow, determine whether the energy storage device 20 is full of electric energy according to the electric energy data, close the electric energy output of the energy storage device 20 when the energy storage device 20 is full of electric energy, and control the electric energy output by the water turbine generator 10 to supply power to the load.
Specifically, the hydro-generator 10 is a device for converting water energy into electric energy. The structure of the hydro-generator 10 is not exclusive, and in one embodiment, the hydro-generator 10 includes an impeller, a stator, a rotor, and a bearing, and when water flows into the hydro-generator 10, the impeller is driven by the function and/or potential energy of the water, so as to drive the rotor to perform a magnetic induction line cutting motion in the stator, and further convert the water energy into electric energy, thereby realizing power supply operation for other loads. In the embodiment, the water current power generation system further adopts the energy storage device 20 to store the electric energy generated by the water wheel power generation device 10, so as to directly realize the power supply operation to the load according to the energy storage device 20.
The hydro-generator 10 is directly connected to the switching control device 30 so that the electric energy generated by the hydro-generator 10 can be directly transmitted to the load by the switching control device 30 to be supplied with power, and at the same time, the switching control device 30 can also perform detection as to whether the hydro-generator 10 generates power according to the water flow. It is to be understood that the manner in which the switching control device 30 detects whether the hydro-generator 10 generates power according to the flow of water is not exclusive, and may be implemented by detecting whether the hydro-generator 10 has an output of electric power or whether an impeller in the hydro-generator 10 rotates, or the like. The switching control device 30 may perform the operation of collecting and analyzing the output voltage of the hydro-generator 10 in real time, as explained based on whether the hydro-generator 10 has the output of the electric energy, and when the output voltage of the hydro-generator 10 is collected to be greater than 0, it is explained that the hydro-generator 10 starts the power generation operation at this time.
When the hydro-generator 10 starts to generate electricity, the generated electricity has two output lines, one of which is directly transmitted to the switching control device 30 and then transmitted to the load through the switching control device 30; the second is to transmit the electric energy to the energy storage device 20 for storage, and then transmit the electric energy to the load through the switch control device 30 by the discharge of the energy storage device 20. And the particular choice of which line to power the load in a water current power generation system depends on the electrical energy stored by the energy storage device 20. Therefore, when the water turbine generator 10 generates power according to the input water flow, the switch control device 30 can collect the electric energy data stored in the energy storage device 20 in real time, so as to determine the amount of electric energy stored in the energy storage device 20.
It should be noted that the type of energy storage device 20 is not exclusive and in one embodiment, the energy storage device 20 may be a battery. The energy storage device 20 generally has a limited amount of electrical energy that can be stored, and when the electrical energy stored in the energy storage device 20 reaches its maximum amount of stored electrical energy, if the energy storage device 20 continues to be charged, the energy storage device 20 will enter a continuous charging and discharging state. That is, after the energy storage device 20 supplies (discharges) a part of the electric energy to the load through the switching control device 30, the electric energy generated by the hydraulic generator 10 will be immediately supplemented to the energy storage device 20, and the service life of the energy storage device 20 is seriously consumed. Therefore, in the continuous power generation process of the water turbine power generation apparatus 10 in the embodiment, the switch control apparatus 30 collects the electric energy data stored in the energy storage device 20 in real time for analysis, so that when the energy storage device is full of electric energy, the discharging operation can be stopped in time.
Specifically, when the energy storage device 20 is full of electric energy, the switch control device 30 cuts off a power supply line of the energy storage device 20-the switch control device 30-the load, and simultaneously opens a power supply line of the water wheel power generation device 10-the switch control device 30-the load, so that the electric energy generated by the water wheel power generation device 10 is directly transmitted to the load for power supply, thereby avoiding frequent charging and discharging operations of the energy storage device 20 and effectively prolonging the service life of the energy storage device 20.
It is understood that, in one embodiment, the switch control device 30 is further configured to control the electrical energy output by the energy storage device 20 to supply power to the load when the hydro-generator 10 of the water flow power generation system is not generating power according to the input water flow. That is, when the switching control device 30 detects that the output voltage of the hydraulic generator 10 is 0, it is determined that the hydraulic generator 10 is not generating power. In order to realize the power supply operation of the load, the switching control device 30 only needs to control the line of the energy storage device 20-the switching control device 30-the load to be opened, and the power supply operation of the load is realized through the discharge of the energy storage device 20.
Further, in one embodiment, the switch control device 30 is further configured to control the power output by the energy storage device 20 to supply power to the load when the energy storage device 20 is not fully charged with power. When the switching control device 30 determines whether the energy storage device 20 is full of electric energy according to the acquired electric energy data, the situation that the electric energy of the energy storage device 20 is not full of electric energy may also occur, at this time, a line of the energy storage device 20-the switching control device 30-a load is also selected to supply power, and the energy storage device 20 may also discharge when the water turbine generator 10 charges the energy storage device 20, and the electric energy is supplied to the load through the switching control device 30.
It should be noted that, in one embodiment, the height between the water inlet and the impeller can be properly increased to ensure that the impeller is driven to rotate when the water flows through the impeller, so that the whole power generation operation is normally performed, and the kinetic energy and the potential energy of the water flow are effectively converted into electric energy. It can be understood that the height from the water flow inlet to the impeller is not unique, and the water flow inlet can be specifically set in combination with the application scene of the water flow power generation system, and the water flow power generation system can be applied to various different water consuming appliances or devices as long as the water flow power generation system at the height can be normally integrated and set in the water consuming appliances or devices. Furthermore, in one embodiment, the water flow pipeline is structurally processed, water pressure of the water inlet is increased, so that the flow velocity of water is increased, kinetic energy and potential energy of the water are effectively utilized, the kinetic energy and the potential energy drive the impeller blades to rotate and convert the impeller blades into mechanical energy, and finally power generation operation is achieved.
Referring to fig. 2, in one embodiment, the water flow power generation system further includes a voltage stabilizer 40, the hydro-generator 10 is connected to the voltage stabilizer 40, the voltage stabilizer 40 is connected to the energy storage device 20 and the switching control device 30, and the switching control device 30 is connected to the hydro-generator 10.
Specifically, since the hydro-generator 10 directly performs the impeller-driven power generation operation using the flow of the tap water, the water pressure of the flow of the tap water is unstable, resulting in unstable voltage output from the hydro-generator. Therefore, in order to avoid the unstable voltage affecting the normal operation of the energy storage device 20 and the load at the later stage, in this embodiment, a voltage stabilizer 40 is further connected between the water turbine generator 10 and other devices at the later stage to stabilize the voltage of the water turbine generator 10. It is to be understood that the type of the voltage stabilizer 40 is not exclusive as long as it can convert the unstable voltage output from the hydro-generator 10 into the stable voltage output.
Referring to fig. 2, in one embodiment, the switching control device 30 includes a controller 31 and a switching device 32, the switching device 32 is connected to the energy storage device 20 and the voltage stabilizer 40, the controller 31 is connected to the switching device 32, the energy storage device 20 and the hydro-generator 10, and the switching device 32 is connected to the load.
Specifically, in the present embodiment, the controller 31 and the switch device 32 are adopted to implement the control operation of the water flow power generation system, the controller 31 collects and analyzes the electric energy data, and the water turbine power generation device 10 determines whether to generate power according to the water flow, and both the electric energy output of the energy storage device 20 and the electric energy output of the voltage stabilizer 40 flow into the subsequent load through the switch device 32, so as to implement power supply to the subsequent load. When the controller 31 detects that the energy storage device 20 is fully charged with electric energy during power generation, the controller 31 sends a corresponding control signal to the switching device 32, so that the part of the switching device 32 connected with the energy storage device 20 is disconnected, and the part of the switching device 32 connected with the voltage stabilizing device 40 is conducted, so that the electric energy generated by the water turbine power generation device 10 is directly supplied to a load for power supply operation after voltage stabilizing processing; when the controller 31 detects that the energy storage device 20 is not fully charged with electric energy, the controller 31 sends a corresponding control signal to the switching device 32, so that the portion of the switching device 32 connected to the energy storage device 20 is turned on, and the portion of the switching device 32 connected to the voltage stabilizer 40 is turned off, so that the electric energy generated by the hydro-generator 10 charges the energy storage device 20, and the electric energy stored in the energy storage device 20 is used for supplying power to the load. Further, when the controller 31 detects that the hydro-generator 10 is not generating power, the controller 31 sends a corresponding control signal to the switching device 32, so that the portion of the switching device 32 connected to the energy storage device 20 is turned on, and the portion of the switching device 32 connected to the voltage stabilizer 40 is turned off, and the electric energy stored in the energy storage device 20 is directly used to supply power to the load.
Referring to fig. 3, in an embodiment, the water current power generation system further includes a voltage divider, and the energy storage device 20 is connected to the controller 31 through the voltage divider.
Specifically, the voltage divider may be a voltage divider circuit, the energy storage device 20 is connected to the controller 31 through the voltage divider circuit, and the controller 31 analyzes the voltage change (i.e. the electric energy data of the energy storage device 20) at two ends of the resistance of the voltage divider circuit by collecting, that is, the detection operation of whether the energy storage device 20 is full of electric energy may be implemented. It is understood that the manner of detecting whether the energy storage device 20 is fully charged is not exclusive, and in another embodiment, the detection may be implemented by an electric quantity detection chip.
The water flow power generation system generates power by using input water flow, and the switch control device 30 detects the electric energy stored in the energy storage device 20 in real time during power generation, and when the electric energy of the energy storage device 20 is fully stored, the load is directly supplied with power only by the electric energy generated by the water wheel power generation device 10. Through above-mentioned scheme, no longer discharge when energy storage device 20 is full of the electric energy, can avoid hydraulic generator 10 persistence power generation in-process, energy storage device 20 frequently charges and discharges, has effectively prolonged energy storage device 20's life to solve the problem that traditional rivers electricity generation purifier life is low.
Referring to fig. 4, a method for controlling a water flow power generation system includes step S100, step S200, and step S300.
Step S100, when the water wheel power generation device of the water flow power generation system generates power according to the input water flow, acquiring the electric energy data of the energy storage device of the water flow power generation system.
Specifically, referring to fig. 1 to 3, the water turbine generator 10 is a device for converting water energy into electric energy. The structure of the hydro-generator 10 is not exclusive, and in one embodiment, the hydro-generator 10 includes an impeller, a stator, a rotor, and a bearing, and when water flows into the hydro-generator 10, the impeller is driven by the function and/or potential energy of the water, so as to drive the rotor to perform a magnetic induction line cutting motion in the stator, and further convert the water energy into electric energy, thereby realizing power supply operation for other loads. In the embodiment, the water flow power generation system further adopts the energy storage device 20 to store the electric energy of the water wheel power generation device 10, so as to directly realize the power supply operation to the load according to the energy storage device 20.
The hydro-generator 10 is directly connected to the switching control device 30 so that the electric energy generated by the hydro-generator 10 can be directly transmitted to the load by the switching control device 30 to be supplied with power, and at the same time, the switching control device 30 can also perform detection as to whether the hydro-generator 10 generates power according to the water flow. It is to be understood that the manner in which the switching control device 30 detects whether the hydro-generator 10 generates power according to the flow of water is not exclusive, and may be implemented by detecting whether the hydro-generator 10 has an output of electric power or whether an impeller in the hydro-generator 10 rotates, or the like. The switching control device 30 may perform the operation of collecting and analyzing the output voltage of the hydro-generator 10 in real time, as explained based on whether the hydro-generator 10 has the output of the electric energy, and when the output voltage of the hydro-generator 10 is collected to be greater than 0, it is explained that the hydro-generator 10 starts the power generation operation at this time.
When the hydro-generator 10 starts to generate electricity, the generated electricity has two output lines, one of which is directly transmitted to the switching control device 30 and then transmitted to the load through the switching control device 30; the second is to transmit the electric energy to the energy storage device 20 for storage, and then transmit the electric energy to the load through the switch control device 30 by the discharge of the energy storage device 20. And the particular choice of which line to power the load in a water current power generation system depends on the electrical energy stored by the energy storage device 20. Therefore, when the water turbine generator 10 generates power according to the input water flow, the switch control device 30 can collect the electric energy data stored in the energy storage device 20 in real time, so as to determine the amount of electric energy stored in the energy storage device 20.
Step S200, determining whether the energy storage device 20 is full of electric energy according to the electric energy data.
Specifically, the energy storage device 20 generally has a limited amount of electrical energy that can be stored, and when the electrical energy stored in the energy storage device 20 reaches its maximum amount of stored electrical energy, if the energy storage device 20 is continuously charged, the energy storage device 20 will enter a continuous charging and discharging state. That is, after the energy storage device 20 supplies (discharges) a part of the electric energy to the load through the switching control device 30, the electric energy generated by the hydraulic generator 10 will be immediately supplemented to the energy storage device 20, and the service life of the energy storage device 20 is seriously consumed. Therefore, in the continuous power generation process of the water turbine power generation apparatus 10 in the embodiment, the switch control apparatus 30 collects the electric energy data stored in the energy storage device 20 in real time for analysis, so that when the energy storage device is full of electric energy, the discharging operation can be stopped in time.

Specifically, when the energy storage device 20 is full of electric energy, the switch control device 30 cuts off a power supply line of the energy storage device 20-the switch control device 30-the load, and simultaneously opens a power supply line of the water wheel power generation device 10-the switch control device 30-the load, so that the electric energy generated by the water wheel power generation device 10 is directly transmitted to the load for power supply, thereby avoiding frequent charging and discharging operations of the energy storage device 20 and effectively prolonging the service life of the energy storage device 20.
Referring to fig. 5, in an embodiment, the method for controlling a water current power generation system further includes step S500.
Step S500, when the hydraulic generator 10 of the water flow power generation system does not generate power according to the input water flow, controlling the electric energy output by the energy storage device 20 to supply power to the load.
Specifically, taking the example of determining whether or not the hydro-generator 10 is on by voltage detection, when the switching control device 30 detects that the output voltage of the hydro-generator 10 is 0, a determination result is obtained that the hydro-generator 10 is not generating power. In order to realize the power supply operation of the load, the switching control device 30 only needs to control the line of the energy storage device 20-the switching control device 30-the load to be opened, and the power supply operation of the load is realized through the discharge of the energy storage device 20.

In step S400, when the energy storage device 20 is not fully charged with electric energy, the electric energy output by the energy storage device 20 is controlled to supply power to the load.
Specifically, when the switching control device 30 determines whether the energy storage device 20 is full of electric energy according to the acquired electric energy data, the situation that the electric energy of the energy storage device 20 is not full of electric energy may also occur, at this time, a line of the energy storage device 20-the switching control device 30-the load is also selected to supply power, and the energy storage device 20 may also discharge while the hydraulic generator 10 charges the energy storage device 20, and the electric energy is supplied to the load through the switching control device 30.
In the control method of the water flow power generation system, the water flow power generation system generates power by using the input water flow, the switch control device 30 detects the electric energy stored in the energy storage device 20 in real time during the power generation process, and when the electric energy of the energy storage device 20 is fully stored, the load is directly supplied with power only by the electric energy generated by the water wheel power generation device 10. Through above-mentioned scheme, no longer discharge when energy storage device 20 is full of the electric energy, can avoid hydraulic generator 10 persistence power generation in-process, energy storage device 20 frequently charges and discharges, has effectively prolonged energy storage device 20's life to solve the problem that traditional rivers electricity generation purifier life is low.
Referring to fig. 7, a control apparatus of a water flow power generation system includes an energy obtaining module 100 of an energy storage device 20, a state detecting module 200 of the energy storage device 20, and a power supply control module 300.
The energy storage device 20 and the electric energy obtaining module 100 are configured to obtain electric energy data of the energy storage device 20 of the water flow power generation system when the water turbine power generation device 10 of the water flow power generation system generates power according to the input water flow. The energy storage device 20 state detection module 200 determines whether the energy storage device 20 is full of electric energy according to the electric energy data. The power supply control module 300 is configured to turn off the power output of the energy storage device 20 when the energy storage device 20 is fully charged with power, and control the power output by the hydro-generator 10 to supply power to the load.
