Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of power generation equipment, and particularly relates to a vertical flywheel water gravity generator using water gravity and vertical flywheel to generate power. BACKGROUND

[0002] In the field of energy, the large-scale development and utilization of traditional fossil energy (such as coal, oil, and natural gas) has provided core power for social development, but has also caused serious environmental pollution, excessive greenhouse gas emissions, and accelerated depletion of fossil resources. Under this background, the research and development and wide application of clean energy power generation technology have become the core focus of the transformation and upgrading of the energy industry, and hydropower has been one of the key research directions in the field of clean energy for a long time due to its natural advantages of "renewable and low pollution".

[0003] However, the traditional hydropower mode has significant and difficult-to-avoid limitations: first, it is extremely dependent on natural hydrological conditions and needs to rely on specific geographical environments such as river natural drop and large reservoirs for construction, which not only leads to strict restrictions on the site selection of power stations, but also significantly lengthens the construction period and requires a large amount of funds to be invested in the construction of water conservancy hubs, power transmission networks, and other supporting facilities; second, the stability of power generation is greatly affected by seasonal and climatic factors, and the fluctuation range of power generation in flood season and dry season is extremely large, which makes it difficult to achieve effective popularization and application in mountainous areas, islands, and other regions with unstable water sources, and also makes it difficult to flexibly meet the needs of dispersed power consumption scenarios such as small and medium-sized enterprises, residential areas, and tourist attractions for "continuous and stable power supply".

[0004] To break through the limitations of traditional hydropower, some power generation devices based on water medium circulation have emerged in the prior art, but these devices still have many defects that need to be solved: on the one hand, the structure design of some devices is too complex, involving a large number of precision mechanical parts and complex intelligent control logic, which not only increases the manufacturing difficulty, but also increases the subsequent operation and maintenance cost, making it difficult for small and medium-sized enterprises or individual users to afford; on the other hand, the energy conversion efficiency of the circulating power generation is low, and the electric energy consumed in the pumping process is close to or even exceeds the electric energy output by the power generation device, which cannot realize "energy positive income" and completely loses the economy of energy utilization; in addition, a considerable part of the devices consume a large amount of water medium, and need to frequently supplement a large amount of water resources in the long-term operation process, which not only significantly increases the operation cost, but also directly depends on the supply capacity of regional water resources, further limiting its application in water shortage areas or unstable water source scenarios.

[0005] At the same time, with the rapid development of distributed energy system, the society has an increasingly urgent demand for "small, low threshold access, high efficiency conversion, water-saving operation" power generation equipment - for example, the power supply guarantee in remote mountainous areas needs to be free from the dependence on long-distance power transmission network, island tourist areas hope to improve the tourist experience through energy self-sufficiency, and small and medium-sized enterprises also need cost-controllable backup power supply to cope with the risk of power grid fluctuation. Under the dual demand, developing a new type of power generation device that can break through the geographical and water source restrictions of traditional hydroelectric power generation, take water gravity as the core driving force, and has a controllable investment cost and a high cycle efficiency, has become a key direction to solve the contradiction between current technical bottlenecks and market demand. SUMMARY

[0006] The present application aims to solve the problems of high water source dependence, high power generation cost and low cycle efficiency in the prior art, and provides a vertical flywheel water gravity generator which circulates with water as the medium, has low water consumption in long-term operation, and is suitable for multiple scenes.

[0007] To achieve the above-mentioned purpose, the present application realizes the following technical scheme:

[0008] A vertical flywheel water gravity generator, comprising a vertical flywheel, a circulating water tank, a water guide pipe, a submersible pump, a support structure frame, a low-speed generator and a power program controller.

[0009] The vertical flywheel is circumferentially distributed with a plurality of closed circulating water tanks; the submersible pump is used to pump water to the high-position circulating water tank; the water guide pipe connects the submersible pump and the circulating water tank; the support structure frame is used to support the vertical flywheel and the submersible pump; the low-speed generator is connected with the main shaft of the vertical flywheel and generates electricity by using the rotational moment of the vertical flywheel; and the power program controller controls the start and stop of the submersible pump according to the rotation angle of the vertical flywheel, and controls the distribution of generator electric energy, so that part of the electric energy generated by the generator is supplied to the submersible pump for circulation and part of the electric energy is transmitted to the external network.

[0010] Further, the power program controller controls the submersible pump to start when the circulating water tank rotates to a set 290° angle low position, and to stop when the circulating water tank rotates to a 250° angle, and the single operation time of each submersible pump is 2-3 seconds.

[0011] Further, the running speed of the vertical flywheel is 6-8 revolutions per minute.

[0012] Further, the circulating water tank is a closed structure, and the circulating system of the generator circulates with water as the medium, has low water consumption in long-term operation and can be replenished.

[0013] Further, when the vertical flywheel diameter is 8 meters, 6 groups of 12 circulating water tanks are distributed in the circumferential direction, the matching submersible pump power is 15 kW, the lift is 12 meters, the flow is 400 T / h, and the power of the low-speed generator is 500 kw.

[0014] Compared with the prior art, the beneficial effects of the present application are as follows:

[0015] 1. High efficiency and water saving: water is used as the circulating medium, and the water quality cost is low; each group of circulating water tanks is a closed structure, and the water consumption is very small during long-term operation, and only a small amount of water needs to be supplemented regularly.

[0016] 2. Strong scene adaptability: can be installed and applied in mountainous areas, plains, islands, small and medium-sized enterprises, hotels, residential areas, tourist attractions, and even small and medium-sized hydropower stations with unstable water sources.

[0017] 3. Investment and benefit advantage: low investment cost, quick effect, high benefit; the power generation is dozens of times the power consumption of the submersible pump (for example, in the embodiment, the 500kw power generation is about 30 times the power consumption of the 15kw submersible pump), and the energy utilization efficiency and economic value are significant.

For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0025] As shown in Figure 1 , 2 A vertical flywheel water gravity generator of the present application is characterized by:

[0026] It comprises a vertical flywheel 1, a circulating water tank 2, a submersible pump 3, a water guide pipe 4, a support structure frame 5, a low-speed generator 6 and a power program controller 7, and is characterized by:

[0027] The vertical flywheel 1 is uniformly distributed with a plurality of closed circulating water tanks 2 in the circumferential direction, which is used to generate a rotating torque by the gravity difference of water to drive itself to rotate around the main shaft;

[0028] The circulating water tank 2 is a closed structure and contains water medium inside; when the vertical flywheel rotates, the difference between the gravity of the water in the high-position water tank sinking and the gravity of the water in the low-position water tank rising after water replenishment is used to push the flywheel to continuously rotate;

[0029] The submersible pump 3 is controlled by the power program controller 7, and is used to pump the water in the circulating water tank in the low-position state to the circulating water tank in the high-position state; when the circulating water tank rotates to the low-position at a set angle of 290°, the submersible pump is automatically started; when it rotates to an angle of 250°, the submersible pump is automatically stopped, and the single operation time of each submersible pump is 2-3 seconds;

[0030] The water guide pipe 4 connects the submersible pump 3 and the circulating water tank 2 to provide a channel for water transportation;

[0031] The support structure frame 5 is used to support all components such as the vertical flywheel 1, the submersible pump 3 and the low-speed generator 6, and to ensure the structural stability of the device;

[0032] Low-speed generator 6 is directly connected with the main shaft of vertical flywheel 1, and the generated torque is used to drive the generator;

[0033] Power program controller 7 has the functions of "angle detection" and "power distribution":

[0034] Angle detection: according to the rotation angle of the vertical flywheel, the start-stop timing of the submersible pump is accurately controlled;

[0035] Power distribution: after the generator is normally operated, a small part of the generated power is transmitted to the submersible pump to maintain the circulating water pumping, and most of the power is transmitted to the external network (such as the municipal power grid or the user power grid).

[0036] Operating principle

[0037] Initial stage: according to the power generation requirement, the vertical flywheel is set to operate at a speed of 6-8 revolutions per minute;

[0038] Water pumping cycle: the power program controller controls the submersible pump, when the circulating water tank rotates to 290° (low position), the submersible pump starts to pump water to the upper high position of the circulating water tank through the water guide pipe; when the water tank rotates to 250°, the submersible pump is turned off (single operation for 2-3 seconds);

[0039] Torque generation: the water in the high-position circulating water tank sinks due to gravity, pushing the vertical flywheel to rotate; using the "lever principle between the flywheel outer ring water tank and the main shaft", the flywheel main shaft obtains a biasing torque (torsion);

[0040] Power generation and power distribution: the biasing torque of the main shaft drives the low-speed generator to rotate and generate electricity; after the generator is normally operated, the standby starting power is turned off, a small part of the generated power is supplied to the submersible pump through the power supply circuit for circulating water pumping (water transportation is completed through the water guide pipe), and most of the power is transmitted to the external network to obtain benefits. Specific embodiments:

[0042] Taking the embodiment of "flywheel diameter of 8 meters" as an example, the details are as follows:

[0043] Component matching: 6 groups of 12 circulating water tanks are distributed circumferentially on the vertical flywheel; the submersible pump is selected to be a model produced in Shanghai with a power of 15 kW, a lift of 12 meters, and a flow of 400 T / h (about 111 kg / s); the power matching of the low-speed generator is 500 kW;

[0044] Torque calculation: the torque generated by the gravity of water in a single circulating water tank is "111 kg / s (water flow) x 4 meters (flywheel radius, i.e. the arm) = 2220 kg / s"; the total torque (torque) obtained by the simultaneous sinking of 5 water tanks filled with water on one side of the vertical flywheel main shaft is 2220 kg / s, which can drive a 500 kw low-speed generator to operate; when the generator speed is 700 rpm, the required driving torque is about 800-900 kg / s, which can be stably provided by the flywheel;

[0045] Power generation and energy consumption ratio: the 500 kw power generated by the generator is about 30 times the 15 kw power consumption of the submersible pump, and the output power is proportional to the flywheel radius and the power of the submersible pump;

[0046] Installation and operation: the vertical flywheel is fixed by the support structure frame to ensure its flexible rotation around the main shaft; the water guide pipe connecting the submersible pump and the circulating water tank ensures the smooth water pumping path; the power supply program controller is electrically connected with the submersible pump and the low-speed generator to realize the automatic control of "angle detection-submersible pump start-stop-electricity distribution"; during operation, the above-mentioned "water pumping-gravity driving-power generation-electricity distribution" cycle continues to work, meeting the power supply demand of different scenes.

[0047] The above describes the present application and its embodiments, which is not limited, and the drawings shown are only one of the embodiments of the present application, and the actual structure is not limited thereto. In summary, if a person skilled in the art is inspired by it, without departing from the purpose of the present application, without creative design, similar structure and embodiments of the technical solution can be designed, which shall belong to the protection scope of the present application.
