Description

Technical Field

[0001] The invention relates to the technical field of hydropower generation, and in particular to water circulation hydropower generation equipment. Background Art

[0002] Carbon neutrality, a term for energy conservation and emission reduction, refers to the total amount of greenhouse gas emissions directly or indirectly generated by an enterprise, group or individual within a certain period of time, which is offset by planting trees, energy conservation and emission reduction, to achieve "zero emissions" of carbon dioxide. Carbon peak refers to the period when carbon emissions enter a plateau and then enter a steady decline. Simply put, it means that carbon dioxide emissions "break even".

[0003] "Carbon" refers to natural resources such as oil, coal, and wood that are composed of carbon elements. The more "carbon" is consumed, the more "carbon dioxide", the culprit of global warming, is produced. The means to reduce carbon dioxide emissions are: first, carbon sequestration, mainly natural carbon such as soil, forests and oceans will absorb and store carbon dioxide in the air. What humans can do is to plant trees; second, carbon offset, by investing in the development of renewable energy and low-carbon clean technology, reducing carbon dioxide emissions in one industry to offset emissions in another industry. The unit of calculation of the offset is tons of carbon dioxide equivalent. Once carbon dioxide emissions are completely eliminated, we can enter a net zero carbon society.

[0004] With the continuous growth of global energy demand and the increasing prominence of environmental problems, the development and utilization of clean energy has become an important issue in today's society. As a renewable and clean energy form, hydropower has abundant resources and broad application prospects. Traditional hydropower generation is a common renewable clean energy generation method, but traditional hydropower generation has some defects and shortcomings, such as a significant reduction in power generation during the dry season, insufficient power generation throughout the year, especially for some small hydropower stations, resulting in a small proportion in the energy structure. In order to solve this problem, some hydraulic efficiency enhancement technologies have emerged in recent years, such as hydraulic energy storage, hydraulic pumped storage, etc., but these technologies have problems such as high cost and high technical difficulty.

[0005] In the related art, for example, a direct-impulse hydroelectric power generation device disclosed in application number CN201521046806.0 is characterized in that it includes a generator 1, a gearbox 2, a straight shaft box 3 and a turbine 4; the rotating shaft 5 of the turbine 4 is installed horizontally, and the turbine 4 is located between the first wall 7 and the second wall 8, and the blades 6 of the turbine 4 are directly impacted by the water flow to drive the rotating shaft 5 to rotate; the straight shaft box 3 is located in the first wall 7, and the straight shaft box 3 is connected to the gearbox 2, and the gearbox 2 is connected to the generator 1; one end of the rotating shaft 5 is connected to the straight shaft box 3 through a connecting device; a waterproof layer 9 is provided on the side of the first wall 7 close to the water flow, and a steel plate 12 is further provided on the outside of the waterproof layer 9. Although its structure can realize power generation by utilizing the potential energy generated by water power, when it is specifically set, it needs to be installed on the dam body, and at the same time, it needs to rely on the naturally existing water flow to drive its power generation device, which is uncontrollable;

[0006] Therefore, a water circulation hydroelectric power generation equipment is proposed to solve the current shortcomings. Summary of the invention

[0007] The technical problem to be solved by the present invention is to overcome the defects of the above-mentioned technology and provide a water circulation hydroelectric power generation equipment.

[0008] In order to solve the above technical problems, the technical solution provided by the present invention is a water circulation hydroelectric power generation equipment: comprising a plurality of power generation parts;

[0009] A plurality of the power generation parts are arranged side by side and crosswise, and adjacent power generation parts are connected through pipelines, and the power generation parts include circulation parts and drainage pipes arranged at both ends;

[0010] The circulation part includes a water storage tank, a circulating water tank and an external water pool. The external water pool is arranged circumferentially at the lower part of the circulating water tank. A plurality of pumping devices connected to the external water pool through pipelines are arranged circumferentially at the top of the circulating water tank. An upper water pipe is arranged at the bottom of the circulating water tank. The upper water pipe is respectively connected to the corresponding water storage tank and the upper part of the water storage tank in the adjacent circulation part. The bottom of the water storage tank is connected to the external water pool in the corresponding circulation part through a drain pipe. A plurality of boosting bottles are arranged at one end of the drain pipe close to the external water pool. A generator is arranged between the boosting bottle and the external water pool.

[0011] As an improvement, the pumping equipment includes an intermediate water tank, an inlet pipe and an outlet pipe arranged on the circulating water tank. The upper end of the inlet pipe is connected to the upper part of the intermediate water tank, and the lower end is connected to the external water pool. The outlet pipe is spiral-shaped and its two ends are respectively connected to the lower end of the intermediate water tank and the circulating water tank. A drainage switch is provided at the lower part of the outlet pipe, and an air inlet and outlet are provided on the intermediate water tank.

[0012] As an improvement, a support base is provided at the bottom of the water storage tank, and the position of the water storage tank is higher than that of the circulating water tank.

[0013] As an improvement, water inlets are provided on the tops of the water storage tank and the circulating water tank.

[0014] As an improvement, the drain pipe is provided with a control switch and an exhaust pipe.

[0015] As an improvement, the water supply pipe has a U-shaped structure.

[0016] As an improvement, a second drainage switch is provided on the drainage pipe between the booster bottle and the generator.

[0017] As an improvement, a drain pipe connected to an external water pool is provided on the upper part of the circulating water tank.

[0018] As an improvement, boosting pipes are symmetrically arranged on both sides of the upper part of the water inlet pipe and inclined upward, and an air suction port is arranged on the boosting pipe. The water inlet pipe is provided with a water switch between the intermediate water tank and the boosting pipe.

[0019] As an improvement, a connecting water pipe is provided between the drain pipe and the water inlet pipe, a water tank is provided on the drain pipe close to the connecting water pipe, and a water tank water switch is provided below the water tank.

[0020] The advantages of the present invention compared with the prior art are:

[0021] 1. Multiple power generation units are arranged side by side and crosswise, and adjacent power generation units are connected through pipelines to form a complete circulation system. The modular design can flexibly adjust the power generation scale according to actual needs, thereby improving the adaptability and scalability of the system;

[0022] 2. The water storage tank and the circulating water tank are connected through the upper water pipe to form a multi-level water storage structure. The water storage tank is located higher than the circulating water tank, and the gravity potential energy is used to increase the water flow speed. The bottom of the circulating water tank is a conical structure to ensure the water pressure and ensure that the water flows steadily to the water storage tank. The external water pool surrounds the lower part of the circulating water tank and is connected to the circulating water tank through a pumping device. At the same time, vacuum technology is used to form a complete circulation system;

[0023] 3. By driving the generator to generate electricity through water circulation, it can achieve energy self-sufficiency to a certain extent, reduce dependence on external power sources, and reduce operating costs;

[0024] 4. By designing single or multiple circulating hydroelectric power generation equipment in a bidirectional manner, the energy of the slope is used to support the weight of the water pipe, greatly reducing the cost of support;

[0025] 5. The overall operation power generation principle is to store power by the length of the water pipe and the fluidity of the water flow. The water tank is an important starting point for power storage. The more water in the water tank, the better, and the power storage point will also increase. The higher the inclination of the water pipe, the greater the power storage. The longer the inclination of the water pipe, the greater the power storage. The wider the water pipe, the greater the power storage. When the water flow produces fluidity, the power storage will also increase.

DETAILED DESCRIPTION

[0035] In order to make the purpose, technical solution and advantages of the embodiments of the invention clearer, the technical solution in the embodiments of the invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the invention. Obviously, the described embodiments are part of the embodiments of the invention, not all of the embodiments. Generally, the components of the embodiments of the invention described and shown in the drawings here can be arranged and designed in various different configurations.

[0037] In addition, the terms "horizontal", "vertical", "overhanging" and the like do not mean that the components must be absolutely horizontal or overhanging, but can be slightly tilted. For example, "horizontal" only means that its direction is more horizontal than "vertical", and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0038] In the description of the embodiments of the invention, "a plurality of" means at least two.

[0039] In the description of the embodiments of the invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "install", "connect", and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal connection of two components. For ordinary technicians in this field, the specific meanings of the above terms in the invention can be understood according to specific circumstances.

[0040] As shown in the accompanying drawings, a water cycle hydroelectric power generation equipment includes a plurality of power generation parts;

[0041] A plurality of the power generation parts are arranged side by side and crosswise, and adjacent power generation parts are connected by pipelines. The power generation part includes a circulation part and a drainage pipe 1 arranged at both ends;

[0042] The circulation part includes a water storage tank 2, a circulating water tank 3 and an external water pool 4. A water inlet 11 is provided at the top of the water storage tank 2 and the circulating water tank 3. Through the setting of the water inlet 11, water can be injected into the water storage tank 2 and the circulating water tank 3, or the water inlet 11 can be used as an exhaust port to realize the exhaust operation of the air in the water storage tank 2 and the circulating water tank 3.

[0043] A support base 10 is provided at the bottom of the water storage tank 2, and the position of the water storage tank 2 is higher than that of the circulating water tank 3. During implementation, the support base 10 is made of concrete, and its interior is a hollow structure, which can be used for filling garbage soil and construction waste to achieve garbage utilization.

[0044] An external water pool 4 is provided around the lower part of the circulating water tank 3. The external water pool 4 is an annular structure and is arranged around the lower part of the circulating water tank 3. In specific implementation, the external water pool 4 can be connected, which is conducive to the water injection operation.

[0045] The top of the circulating water tank 3 is provided with a plurality of pumping devices 5 connected to the external water pool 4 through pipelines. Through the arrangement of the pumping devices 5, the water in the external water pool 4 can be transported to the circulating water tank 3;

[0046] Specifically, the pumping equipment 5 includes an intermediate water tank 51, an inlet pipe 52 and an outlet pipe 53 arranged on the circulating water tank 3. The upper end of the inlet pipe 52 is connected to the upper part of the intermediate water tank 51, and the lower end is connected to the external water pool 4. The outlet pipe 53 is spiral and its two ends are respectively connected to the lower end of the intermediate water tank 51 and the circulating water tank 3. The intermediate water tank 51 is provided with an air inlet and outlet 54.

[0047] Furthermore, a drainage switch 9 is provided at the lower part of the water outlet pipe 53;

[0048] During use, the pumping device 5 uses the negative pressure suction principle. The technical principle is to use the force to pull and use the force to release. At the same time, first close the water switch 18, then close the drain switch 9, and inject water into the middle water tank 51 from the air inlet and outlet 54, and the gas is discharged from the exhaust port 54 until the water outlet pipe 53 is filled with water and the middle water tank 51 is filled with nine-tenths of water. Then, the air is pumped out from the air pump port 54 of the water tank. Some air pressure is needed to support the opening of the water switch 18 so that the gas in the water tank will not flow to the boosting pipe 16, and then from the first group of boosting pipes at the bottom to the second group of boosting pipes and the third group of boosting pipes 16, the air pump port 1 7, air is simultaneously pumped out until the water fills the entire volume of the boosting pipe 16. At this time, the boosting pipe 16 bears most of the vacuum pressure of the water inlet pipe 52. By utilizing the negative pressure suction principle, air is pumped out through the air inlet and outlet 54 of the intermediate water tank 51, and then a part of the water switch 18 of the water inlet pipe 52 is opened, and the air in the intermediate water tank 51 is completely pumped out through the air inlet and outlet 54 of the intermediate water tank 51. Then, the air inlet and outlet 54 of the intermediate water tank 51 are closed, and then the water switch 18 of the water inlet pipe 52 is fully opened. At this time, the vacuum pressure borne by the intermediate water tank 51 is relatively small, that is, most of the vacuum pressure is in the boosting pipe 16. (The boosting pipes are symmetrically arranged on both sides of the water inlet pipe 52, and the vacuum pressure inside the boosting pipe 16 is inclined downward. Through experiments on a small water pipe, as long as there is enough negative pressure inside the water pipe, the water source can maintain a certain balance in the water pipe. By utilizing the principle of negative pressure pumping, as long as the water switch 18 is not turned on, the negative pressure inside the water pipe 52 is large enough. Even if the water in the external water pool 4 is lower than the water inlet pipe 52, as long as the water inlet pipe 52 maintains a balanced state, the water inside it will not all flow into the external water pool 4. The technology is the principle of negative pressure suction).

[0049] A drain pipe 15 connected to the external water pool 4 is provided on the upper part of the circulating water tank 3. That is, when the amount of water in the external water pool 4 is less, a switch is also provided on the drain pipe 15. By opening the switch, part of the water can be transported from the circulating water tank 3 to the external water pool 4. Specifically, the drainage volume of the drain pipe 15 is the water pumped by the pumping equipment 5 minus the consumption of the circulating water pool. At the same time, the water pumped by the pumping equipment 5 must be more than 1.5 times the consumption of the circulating water pool 4.

[0050] The bottom of the circulating water tank 3 is provided with a water supply pipe 6, and the water supply pipe 6 is respectively connected to the corresponding water storage tank 2 and the upper part of the water storage tank 2 in the adjacent circulation part;

[0051] Specifically, the water supply pipe 6 is a U-shaped structure. Specifically, the water supply pipe 6 is a forked U-shaped structure, which is connected to the corresponding water tank 2 and the upper part of the water tank 2 in the adjacent circulation part, which is beneficial to increase the water supply speed of the water supply pipe 6 to the water tank 2.

[0052] During implementation, the bottom of the circulating water tank 3 is in a conical structure, which can ensure the water pressure of the water flowing through the water supply pipe 6 to ensure that the water in the circulating water tank 3 flows into the water storage tank 2.

[0053] The bottom of the water storage tank 2 is connected to the external water pool 4 in the corresponding circulation part through the drainage pipe 1. Specifically, the diameter of the drainage outlet of the drainage pipe 1 is smaller than or equal to the diameter of the water supply pipe 6.

[0054] The drain pipe 1 is provided with a control switch 12 and an exhaust pipe 13. Specifically, the exhaust pipe 13 is provided with a switch to realize the opening control of the exhaust pipe 13. In a specific implementation, when water is injected into the drain pipe 1, the air in the exhaust pipe 1 can be discharged through the exhaust pipe 13.

[0055] A plurality of booster bottles 7 are provided at one end of the drain pipe 1 close to the external water pool 4. Specifically, the number of the booster bottles 7 can be set according to actual conditions. In the present embodiment, the number of the booster bottles 7 is 3. By providing the booster bottles 7, the flow velocity of the water flowing through the drain pipe 1 is further increased.

[0056] The drain pipe 1 is provided with a generator 8 between the booster bottle 7 and the external water pool 4 , and the generator 8 generates electricity through the water flowing through the drain pipe 1 .

[0057] Furthermore, a drainage switch 2 14 is provided on the drainage pipe 1 between the booster bottle 7 and the generator 8 .

[0058] When the present invention is implemented, first ensure that there is a continuous supply of water to the external water pool 4, and then transport the water in the external water pool 4 to the circulating water tank 3 through the pumping equipment 5, until a certain amount of water is filled in the water supply pipe 6 to support the water inlet pipe 52 of the water storage tank 2, and then turn off the water switch 18, through the first group of boosting pipes at the bottom, then to the second group of boosting water pipes, and then to the third group of boosting water pipes. More groups of boosting pipes can be set according to the situation. First, exhaust air from the exhaust port 17 of each boosting pipe 16 on the left and right, and exhaust air from each of the left and right pipes at the same time until the inside of the boosting pipe 16 is completely filled. At the same time, the water inlet pipe 52 is designed at the intersection of the two boosting pipes 16, and the intersection is at the energy balance point. Water is supplied by utilizing the balance point, which greatly reduces the vacuum pressure of the middle water storage tank 2 and utilizes the negative pressure suction principle.

[0059] Step 2: The continuous water source from the external water pool 4 is transported to the circulating water tank 3 through the pumping equipment 5, and the gas in the circulating water tank 3 is discharged from the water inlet 11 until the circulating water tank 3 is filled and then the water inlet 11 is closed.

[0060] The third step: first close the drainage switch 14, close the water tank switch 24, fill the water tank 23 to one-fifth of the water (the water tank is not in a closed mode, you can add water directly), open the exhaust pipe 13, the exhaust pipe 13 is designed with a switch; close the control switch 12, and transport the water source from the water inlet 11 of the water tank 2 to the water tank until the water pipe between the control switch 12 and the water tank is filled, and then fill the water in the water tank 2 to nine-tenths, and pump air from the water inlet 11. Some gas needs to be pumped out to support the opening of the water switch 18 so that the gas in the water tank 2 will not flow to the boosting pipe 16, and then open some water switches 18 until the water inlet 11 has pumped out the gas inside the water tank 2. At this time, the energy of the water on the water inlet pipe 52 is supported by multiple groups of boosting pipes 16, which greatly reduces the pulling force of the water tank 2 on the water inlet pipe 52. The water tank 2 also has a certain vacuum air pressure, that is, the negative pressure suction principle is used, and finally the water switch 18 is fully opened.

[0061] Step 4: Open some control switches 12, and a steady stream of water is transported from the external pool 4 to the circulating water tank 3 through the pumping equipment 5, and then to the water storage tank 2, and then to the drain pipe 1. The gas in the drain pipe 1 is discharged from the exhaust pipe 13. When the drain pipe 1 has a certain amount of water reaching half of the booster bottle 7, open the switch designed for the booster bottle until the booster bottle 7 is half filled and then closed, and then close the exhaust pipe 13 until the drain pipe 1 is filled. After fully opening the control switch 12, the booster bottle at this time stores some water pressure generated by the height difference of the water pipe, and then open the drainage switch 14 , then open the drainage switch three, the booster bottle 7 will also release some energy to accelerate the water flow, and a complete hydraulic water circulation device is completed. When it reaches full normal operation, a connecting water pipe 19 is provided between the drainage pipe 1 and the water inlet pipe 52 of the water storage tank, and the connecting pipe is provided with a water switch two 20. When the water switch two 20 of the connecting water pipe 19 is turned on, the water switch 22 of the water inlet pipe of the water storage tank is closed, and the drainage switch three 21 should also be closed at the same time. Before closing, it is necessary to ensure that there is no gas inside the connecting water pipe 19, and the water switch 24 of the water tank should also be turned on. When just connected, the connecting water pipe 19 needs buffer time, and the impact of the drainage pipe 1 and some water will flow into the water tank 23 (at this moment, the water inlet pipe 52 has a negative pressure suction principle, and the water in the water inlet pipe 52 will not flow back), until normal operation, the consumed water can be added through the water tank 23. The drainage pipe is connected to the water pipe, which can also achieve the effect of water circulation. 《Overall operation power generation principle: When the water source reaches a certain depth, water pressure will be generated at the bottom. Using the length and height difference of the water pipe, water pressure will be generated inside the bottom of the water pipe. The water tank is an important starting point for power storage. The more water in the water tank, the greater the power storage, and the water pressure at the bottom will also increase. The higher the inclination of the water pipe, the greater the power storage, and the greater the water pressure at the bottom. The longer the inclination of the water pipe, the greater the power storage, and the greater the water pressure at the bottom. The wider the water pipe, the greater the power storage, and the greater the water pressure at the bottom. When the water flow generates fluidity, the force of the water flow will increase. A steady supply of water goes from the external pool to the pumping equipment (the water inlet pipe is designed with multiple sets of booster pipes, which is beneficial to the speed of water supply and reduces the negative pressure suction energy of the water tank), then to the circulating water tank (which can speed up the speed of water supply through the water supply pipe), then to the water storage tank (the water inlet pipe is designed with multiple sets of booster pipes, which is beneficial to the speed of water supply and reduces the energy of the water storage tank pulling the water inlet pipe), and then to the drainage pipe for power generation (a booster bottle is designed to accelerate some fluidity when flowing). The drainage pipe is designed to be connected to the water inlet pipe (which can also achieve water circulation)".

[0062] The present invention and its embodiments are described above, and such description is not restrictive. The drawings show only one embodiment of the present invention, and the actual structure is not limited thereto. In short, if ordinary technicians in the field are inspired by it, without departing from the purpose of the invention, they can design a structure and embodiment similar to the technical solution without creativity, which should belong to the protection scope of the present invention.
