Description

Technical Field

[0001] The present invention relates to the technical field of reservoirs, and in particular to a reservoir adaptive cogeneration component, system and method. Background Art

[0002] Pumped-storage power stations have functions such as energy storage and peak load regulation. The principle is to release water to generate electricity when the power grid load is at its peak, and pump water to store energy when the power grid load is at its low point. Therefore, according to the need to release water and pump water during peak and valley periods of the power grid, the upper and lower reservoirs of pumped-storage power stations have the characteristics of frequent water level fluctuations. Since pumped-storage reservoirs are usually U-shaped structures with a cross-section that is wide at the top and narrow at the bottom, the surface water area of ​​the pumped-storage reservoir when the water level is high will be greater than the surface water area of ​​the pumped-storage reservoir when the water level is low.

According to relevant forecasts, the total installed capacity of my country's pumped storage power stations will reach 100 million kilowatts by 2025. Therefore, pumped storage power stations are welcoming an opportunity for large-scale construction and development, and secondary development and utilization of pumped storage reservoirs is necessary and has promising prospects.

[0057] like Figure 1 , Figure 2 , Figure 3 and Figure 8 As shown, the solar panel structure 3 includes two solar photovoltaic panels 301 that can be relatively unfolded and folded, and the two adjacent solar photovoltaic panels 301 are rotatably connected by a hinge 2, and the end of the solar photovoltaic panel 301 close to the supporting platform 4 is rotatably connected to the cross bar of the supporting platform 4 by the hinge 2, that is, the end of each solar photovoltaic panel 301 that is away from the other solar photovoltaic panel 301 connected to the hinge 2 is rotatably connected to the cross bar of the supporting platform 4 by the hinge 2. In order to prevent the supporting platform 4 from floating arbitrarily in the pumped storage reservoir 7, each supporting platform 4 is provided with a limit rod 5 on both sides along the length direction, and an angle 601 is provided between the limit rod 5 and the bottom surface of the reservoir 7, and the angle 601 is not equal to 90°. At the same time, the two limit rods 5 set along the length direction of the same supporting platform 4 are set in parallel, that is, the length direction of the supporting platform 4 is the same as the length direction of the solar water pipe and the length direction of the solar photovoltaic panel 301. It should be noted that the height of the limit rod 5 is higher than the height of the pumped storage reservoir 7 in the flood state 701. Figure 4 As shown, the outer periphery of the limiting rod 5 is sleeved with a slip ring 6, and both ends of each supporting platform 4 in the length direction are connected to the slip ring 6 through a connecting rod 602. Figure 1 As shown, the calculation rule of the angle and length of the limit rod 5 is as follows:

[0058]

[0059] Where: f α is the width of the solar photovoltaic panel 301 of the solar panel structure 3 when it is fully folded; f β is the width of the solar photovoltaic panel 301 of the solar panel structure 3 when it is fully unfolded; △f is the width of the solar photovoltaic panel 301 of the solar panel structure 3 when it is fully folded and fully unfolded; H h is the maximum working water depth of the pumped storage reservoir 7; H l is the minimum working water depth of the pumped storage reservoir 7; △H is the working water level difference of the pumped storage reservoir 7; θ is the layout inclination angle of the limit rod 5 (the inclination angle is only on the vertical plane corresponding to the width of the reservoir adaptive cogeneration component); P is the length of the limit rod 5; δ is the reserved length outside the working part of the limit rod 5.

[0060] The maximum area and minimum area occupied by the reservoir adaptive cogeneration assembly composed of two adjacent supporting platforms in the reservoir 7 are shown in the following formula:

[0061]

[0062] Where: S α The surface area of ​​the combined heat and power assembly when the solar photovoltaic panel 301 is fully folded; S β The surface area of ​​the combined heat and power assembly when the solar photovoltaic panel 301 is fully unfolded; l is the length of a single supporting platform 4; w is the width of a single supporting platform 4.

[0063] A reservoir adaptive cogeneration system is provided in a pumped storage reservoir 7, such as Figure 5 , Figure 6 and Figure 7 As shown, it includes five groups of reservoir adaptive cogeneration components, and a water supply tank 8 is respectively provided at the four corners of the bank slope 9 of the pumped storage reservoir 7, wherein three groups of reservoir adaptive cogeneration components are combined together, that is, when the length directions of the supporting platforms 4 of adjacent adaptive components are parallel, a solar panel structure 3 is provided between two adjacent reservoir adaptive cogeneration components. In order to realize the transmission of electric energy and hot water, it also includes a controller, a transmission cable, a transformer and a water pipe. The controller is respectively connected to the solar panel structure 3, the solar hot water pipe structure 1, and the transformer for communication. The transmission cable is connected to the solar panel structure 3 line, and the water pipe is connected to the solar hot water pipe through a pipeline. It should be noted that the solar hot water pipes on the adjacent supporting platforms 4 are connected by pipelines, a water supply pump and a water supply valve are provided between the water supply tank 8 and the solar hot water pipe structure 1, and a water pump and a water valve connected to the solar hot water pipe structure 1 are provided on the bank slope 9. A temperature sensor is provided in the solar hot water pipe of the supporting platform 4, and the temperature sensor is connected to the controller for communication.

[0064] To facilitate the calculation of the area occupied by the reservoir adaptive cogeneration system of the pumped storage reservoir 7 within the reservoir, the formula is as follows:

[0065]

[0066] S l is the area of ​​the pumped storage reservoir 7 when it is at low water level; S u is the area of ​​the pumped storage reservoir 7 when it is at high water level; ∑S α is the sum of the surface areas of all reservoir adaptive cogeneration components arranged in the reservoir when their solar photovoltaic panels 301 are fully folded; ∑S β It is the sum of the surface areas of all the reservoir adaptive cogeneration components arranged in the reservoir 7 when their solar photovoltaic panels 301 are fully unfolded; k is the number of solar panel structures 3 arranged between adjacent reservoir adaptive cogeneration components.

[0067] In addition, the reservoir adaptive cogeneration components and overall total heating capacity of a single pumped storage reservoir 7 are shown as follows:

[0068]

[0069] Where: E i is the heating capacity of a single reservoir adaptive cogeneration component; E s is the total heating capacity of all reservoir adaptive cogeneration components configured in the pumped storage reservoir 7; R(t) is the heating efficiency of the unit length of the solar water heating pipe, which is a function of time t within a day and can be determined by the solar pipe parameters and the average light radiation intensity of the area; n is the number of solar water heating pipes configured in a single reservoir adaptive cogeneration component; l is the length of the solar water heating pipe configured in the reservoir adaptive cogeneration component.

[0070] In the specific implementation process, the water surface area of ​​the pumped water storage reservoir 7 in the flood state 701 increases. Since the supporting platform 4 moves along the limit rod 5 and an angle is set between the limit rod 5 and the bottom surface of the reservoir 7, the spacing between the supporting platforms 4 increases, and the two solar photovoltaic panels 301 of the solar panel structure 3 are unfolded, and the water in the solar hot water pipe is heated by the sun; the water surface area in the dead water state 702 decreases. Since the supporting platform 4 moves along the limit rod 5 and an angle is set between the limit rod 5 and the bottom surface of the reservoir 7, the spacing between the supporting platforms 4 decreases, and the two solar photovoltaic panels 301 of the solar panel structure 3 are folded, and the water in the solar hot water pipe is heated by the sun. The electric energy generated by the solar photovoltaic panel 301 is transmitted to the transformer through the transmission cable, and then merged into the surrounding power grid after the transformer. When the controller receives the temperature of the temperature sensor, when the temperature reaches the preset value, the controller simultaneously opens the water supply valve and the water delivery valve, and starts the water supply pump and the water delivery pump to deliver the hot water in the solar hot water pipe to the user.

[0071] As an alternative implementation, the number of solar water heating pipes arranged on each supporting platform 4 may be 1, 2, 4 or even more.

[0072] As an alternative embodiment, the number of solar photovoltaic panels 301 of a solar panel structure 3 can also be 3, 4 or even more.

[0073] As an alternative embodiment, the number of the water supply tanks 8 can also be 1, 2, 3, 5 or even more.

[0074] Obviously, the above embodiments are merely examples for clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from them are still within the protection scope of the invention.
