Abstract

[0002] With the rapid development of our country, electricity consumption is increasing, and the resources in today's world are limited. In order to leave more resources for our future generations and allow them to have a certain amount of development space, this energy-saving hydropower generator was designed after discussion.
[0003] Currently, there are a wide variety of power generation systems available worldwide, all of which are relatively efficient and of high quality. However, these systems are subject to certain limitations, such as hydropower, thermal power, wind power, solar power, and seawater power generation. Hydropower is limited by water resources and the environment, while thermal power generation, like fuel, is limited worldwide. Wind power also has certain limitations, and seawater power generation is unstable. Of course, the power generation capacity of these natural resources alone falls far short of current social needs. However, the combination of thermal power, nuclear power, diesel power, natural gas power, and other power generation systems can generally meet social needs. However, other power generation sources, besides natural energy, account for a large proportion of the total power generation capacity. Furthermore, these power plants generally consume excessive amounts of energy and have a certain impact on the environment. Utility Model Content

[0013] Beneficial effects
[0014] This utility model provides an energy-saving hydroelectric generator set that solves existing technical problems related to energy consumption. Combining the functions of existing hydroelectric generator sets, this utility model reconfigures the unit structure and utilizes the potential energy and quantity of water. To conserve resources, it can be built in suitable mountainous areas. Taking advantage of mountainous areas, two water tanks can be constructed sequentially from bottom to top. It can also be built in hilly areas or in plain areas. This energy-saving solution utilizes the functions of existing hydroelectric generator sets, storing appropriate levels of water in the tanks sequentially, or using water from a suitable existing reservoir connected to a drainage pipe and connected to a turbine generator set via accessories. Water discharged from the turbine enters a tank a certain distance below. A turbine is installed at the water inlet interface of the lower tank, and the water discharged from the turbine is stored in the lower tank. Simultaneously, the turbine drives a suitable water pump, which pumps water from the lower tank to the upper tank or reservoir. This cycle repeats. For safe operation of the unit, a set of two or more machines can be configured. For example, maintenance and repairs will not affect the operation and power generation of the unit, and the cost sounds high, but in fact it is much lower (at the same power).

Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0018] See also Figure 1 The utility model provides a technical solution: an energy-saving hydroelectric generator set, including a main water tank 1, an intermediate water tank 2 and a lower water tank 3, a main drainage water turbine pump set 4 is connected between the main water tank 1 and the lower water tank 3, a first water turbine generator set 5 is connected between the main water tank 1 and the intermediate water tank 2, a second water turbine 6 is connected between the intermediate water tank 2 and the lower water tank 3, a V-belt set 7 is connected between the second water turbine 6 and the main drainage water turbine pump set 4, and a water supply component is connected to one side of the main water tank 1.
[0019] The water in the lower pool 3 is pumped into the main pool 1 through the main drainage water turbine pump group 4, and the water in the main pool 1 flows downward and passes through the first hydro-generator group 5, converting the energy of the water flow into rotational mechanical energy, thereby enabling the first hydro-generator group 5 to generate electricity. The water in the main pool 1 flows downward into the middle pool 2. At the same time, the water in the middle pool 2 flows through the second turbine 6, converting the energy of the water flow into rotational mechanical energy. When the second turbine 6 is working, the main drainage water turbine pump group 4 can be operated through the V-belt group 7 or direct connection. The water in the middle pool 2 flows downward into the lower pool 3, so that the water in the lower pool 3 can be circulated and supplied to the main pool 1, thereby forming a closed-loop water flow power generation.
[0020] This embodiment is further configured such that the layout of the main pool 1, the middle pool 2 and the lower pool 3 is a stepped structure from top to bottom, the height of the main pool 1 is higher than that of the middle pool 2, and the height of the middle pool 2 is higher than that of the lower pool 3;
[0021] The main water pool 1, the middle water pool 2 and the lower water pool 3 are arranged from high to low so that the water source can flow downward in a stepped manner. The higher the water head and the greater the flow rate, the greater the output power of the first hydro-generator set 5 and the second hydro-turbine 6.
[0022] This embodiment is further configured such that a water pump inlet pipe 8 is connected between the fluid input end of the main drainage water turbine pump group 4 and the lower water tank 3, the free end of the water pump inlet pipe 8 is located below the liquid level of the lower water tank 3, and a water pump discharge pipe 9 is connected between the fluid output end of the main drainage water turbine pump group 4 and the main water tank 1;
[0023] The free end of the water pump inlet pipe 8 is located below the liquid level of the lower water tank 3. The main drainage turbine pump group 4 draws the water in the lower water tank 3 into the water pump discharge pipe 9 through the water pump inlet pipe 8, and guides the water into the main water tank 1 through the water pump discharge pipe 9.

[0025] The free end of the main pool drain pipe 10 is located below the liquid level of the main water pool 1. Since the main water pool 1 is higher than the intermediate water pool 2, the water in the main water pool 1 flows downward through the main pool drain pipe 10 and passes through the first hydro-generator unit 5. The energy of the water flow is converted into rotational mechanical energy, thereby enabling the first hydro-generator unit 5 to generate electricity. After passing through the first hydro-generator unit 5, the water flows into the first hydro-generator drain pipe 11, and the first hydro-generator drain pipe 11 guides the water into the intermediate water pool 2.
[0026] This embodiment is further configured such that a first operating gate valve 12 is provided on the main pool drain pipe 10;
[0027] The first operating gate valve 12 is used to control the opening and closing of the main pool drain pipe 10.
[0028] This embodiment is further configured such that a middle pool drain pipe 13 is provided between the fluid input end of the second hydraulic turbine 6 and the middle pool 2, the free end of the middle pool drain pipe 13 being located below the liquid level of the middle pool 2, and a second hydraulic turbine 6 drain pipe is connected between the fluid output end of the second hydraulic turbine 6 and the lower pool 3;
[0029] The free end of the middle pool drain pipe 13 is located below the liquid level of the middle pool 2. Since the middle pool 2 is higher than the lower pool 3, the water in the middle pool 2 flows downward through the middle pool drain pipe 13 and passes through the second turbine 6. The energy of the water flow is converted into rotational mechanical energy, thereby enabling the second turbine 6 to drain water. After passing through the second turbine 6, the water flows into the drain pipe of the second turbine 6, and the drain pipe of the second turbine 6 guides the water into the lower pool 3.
[0030] This embodiment is further configured such that a second operating gate valve 15 is provided on the middle pool drain pipe 13;
[0031] The second operating gate valve 15 is used to control the opening and closing of the middle pool drain pipe 13.
[0032] This embodiment is further configured such that the water replenishment assembly includes a water replenishment tank 16 and a water replenishment unit 17, a water replenishment inlet pipe 18 is connected between the fluid input end of the water replenishment unit 17 and the water replenishment tank 16, the free end of the water replenishment inlet pipe 18 is located below the liquid level of the water replenishment tank 16, and a water replenishment pipe 19 is connected between the fluid output end of the water replenishment unit 17 and the main water tank 1;
[0033] Since part of the reflux water source is consumed and lost during the water circulation process, the water replenishment unit 17 is started, and the water in the water replenishment tank 16 is introduced into the water replenishment pipe 19 through the water replenishment inlet pipe 18, and the water in the water replenishment tank 16 is introduced into the main water tank 1 through the water replenishment pipe 19, thereby replenishing the water source in the main water tank 1.
