Description

Technical Field

[0001] This utility model relates to the field of renewable energy power generation technology, specifically a multi-energy complementary hybrid power generation device. Background Technology

[0002] Southern China, Guangxi, and Hainan, regions close to the equator, have abundant solar energy. However, some remote mountainous areas and islands still lack access to municipal electricity due to complex terrain and high grid construction costs. Local residents primarily rely on diesel generators for power, resulting in high operating costs and significant pollution. Although these areas often have streams and reservoirs, the lack of suitable technologies prevents the effective conversion of water resources into a stable source of electricity for the load. Since there is no sunlight at night, batteries are often used to store surplus daytime electricity for nighttime use. However, current energy storage batteries are expensive and have short lifespans, leading to excessively high investment and operating costs, thus limiting the widespread adoption of solar power.

[0003] In addition, existing reservoirs are mostly limited to agricultural irrigation and rural drinking water, and have not been effectively integrated with power generation systems. Traditional pumped storage technology has strict requirements on terrain and is difficult to apply in low-lift scenarios, resulting in the untapped potential of water resources for energy storage. Therefore, there is an urgent need for a low-cost, easy-to-deploy hybrid power generation system that deeply integrates solar energy with local water / reservoir resources. Through multi-energy complementarity and intelligent regulation, it can solve the problems of unstable power supply and high costs in remote areas. Utility Model Content

[0023] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numerals in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this disclosure.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0025] like Figure 1 and Figure 2 As shown, this embodiment proposes a multi-energy complementary hybrid power generation device, including a water storage device 1. A water supply pipe 2 is fixedly installed on one side of the water storage device 1. A water turbine generator 3 is fixedly installed at the water outlet of one end of the water supply pipe 2 inside the water storage device 1. The water turbine generator 3 is electrically connected to a controller 4 via wires. The controller 4 is a PLC controller. The controller 4 is electrically connected to a solar power generation device 5 via wires. The controller 4 is electrically connected to a storage battery 6 via wires.

[0026] The height of the water supply pipe 2 is greater than the maximum water level of the water storage device 1. The water flows out from the port of the water supply pipe 2, which drives the water turbine generator 3 to start generating electricity. The water turbine generator 3 and the solar power generation device 5 can supplement each other or generate electricity independently. The water supply pipe 2 is made of multiple sections of pipe with flanges spliced ​​together. It has a simple structure and modular installation, which greatly shortens the downtime for replacing and maintaining single components.

[0027] An electromagnetic flow meter 7 is fixedly installed at one end of the surface of the water pipe 2. The electromagnetic flow meter 7 is electrically connected to the controller 4 through a wire.

[0028] A float check valve 8 is fixedly installed above the surface of the water supply pipe 2, and one end of the float check valve 8 is located inside the water storage device 1.

[0029] The float end of the float check valve 8 is located a certain distance below the water supply pipe 2, so that the water level automatically stops and prevents backflow when it reaches a certain height.

[0030] A filter 9 is installed below the surface of the water supply pipe 2, and the float check valve 8 is located at a height lower than the water supply pipe 2 at one end inside the water storage device 1.

[0031] By reducing sediment blockage through filter 9 and float check valve 8, the maintenance cycle of turbine generator 3 is greatly extended.

[0032] The controller 4 is connected to the power load monitor, solar power generation monitor, hydropower generation monitor, and electromagnetic flow meter monitor. The power load monitor is used to measure the user's power load in real time. The solar power generation monitor is used to measure the power output of the solar power generation device 5. The hydropower generation monitor is used to measure the power output of the hydropower generator 3. The electromagnetic flow meter monitor is used to detect the user's water consumption in real time.

[0033] Both the controller 4 and the hydro-generator 3 are connected to the user's power terminal circuit.

[0034] Specifically, during operation / use of this multi-energy complementary hybrid power generation device: by comparing the power output with the electrical load (electromagnetic flowmeter 7), the controller 4 adjusts the power supply and energy storage. When water is transported through the water pipe 2, the hydro-generator 3 generates electricity, part of which is used by the electromagnetic flowmeter 7, and the other part is used for production and daily life. When solar energy is abundant, the solar power generation device 5 generates electricity, part of which is used by the electromagnetic flowmeter 7, and the surplus electricity is used for production and daily life through the battery 6. When the power generated by the solar power generation device 5 cannot meet the electricity needs of production and daily life, the hydro-generator 3 converts it into electrical energy to connect to the user's circuit for production and daily life. Alternatively, when there is no water input to the hydro-generator 3, the power generated by the solar power generation device 5 is used for production and daily life. During operation, the electricity generated by the hydro-generator 3 is output to the electrical load (electromagnetic flowmeter 7). When water is detected... When the power output of turbine generator 3 is greater than that of electromagnetic flowmeter 7, and the power output of turbine generator 3 meets the power load demand of electromagnetic flowmeter 7 but has a surplus, controller 4 controls the power load switch to open, supplying the surplus power to the user's power load or to the storage battery 6 for storage. When the power load of turbine generator 3 is detected to be equal to that of electromagnetic flowmeter 7, and the power output of turbine generator 3 meets the power load demand of electromagnetic flowmeter 7 but has no surplus, controller 4 controls the switch of turbine generator 3 to supply battery 6 to close, and simultaneously controller 4 controls battery 6 to supply electromagnetic flowmeter 7 to open, supplying power to electromagnetic flowmeter 7. When the power output of solar power is detected to be less than the power load, and the power output of turbine generator 3 cannot meet the power load demand of electromagnetic flowmeter 7, controller 4 controls battery 6 to supply electromagnetic flowmeter 7 to open, supplying power to electromagnetic flowmeter 7.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
