Description

Technical Field

[0001] This utility model relates to the field of tidal power generation technology, and more specifically, to a giant tidal power station. Background Technology

[0002] As is well known, the traditional method of hydroelectric power generation utilizes the potential energy of water flowing from a higher elevation to a lower elevation, converting it into kinetic energy to drive the turbine of a hydroelectric generator. Typically, a reservoir is built at a higher elevation to store water, while the hydroelectric generator is installed at a lower elevation. The water falls from the height, doing work on the turbine blades. This method usually uses a large volume of water impacting relatively small blades, with a large amount of water flowing around the circumference of the blades or between them. Therefore, a significant amount of water power is not fully utilized, resulting in a substantial waste of water resources.

[0003] In today's world, with its increasing energy shortages, how to conserve energy and utilize it fully and effectively has become a crucial issue that must be addressed for global development. Due to severe environmental damage, many rivers have dried up or ceased flowing, resulting in a serious lack of hydropower resources. Besides improving hydroelectric generators to increase their power generation efficiency, people have also considered utilizing tidal power for electricity generation.

[0004] There are many existing power plants that utilize tidal energy, but some giant tidal power plants still have the following problems: it is inconvenient to utilize the kinetic energy generated by the flow of seawater during high and low tides for power generation.

[0005] Therefore, a giant tidal power station is proposed. Summary of the Invention

[0006] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a giant tidal power station.

[0007] The objective of this utility model is achieved through the following technical solution:

[0008] A giant tidal power station includes parallel water inlet channels and drainage channels, which are separated by a partition wall. Several power generation turbines are arranged in a straight array on the partition wall along the extension direction of the water inlet channels. Both the water inlet channels and the drainage channels have inlets and outlets. During high tide, seawater flows into the water inlet channels from the inlets. During low tide, the seawater entering the water inlet channels can flow to the outlets of the drainage channels through the inlets.

[0009] Furthermore, this utility model also includes two cofferdams that are spaced apart and interconnected, with the water inlet channel and the water outlet channel located between the two cofferdams, and the water outlet of the water inlet channel and the water inlet channel of the water outlet channel respectively connected to the two cofferdams.

[0010] Furthermore, in this utility model, a first gate is provided at the inlet of the water inlet channel, a second gate is provided at the outlet of the water inlet channel, a third gate is provided at the inlet of the water inlet channel, and a fourth gate is provided at the outlet of the water inlet channel.

[0011] The beneficial effects of this utility model are:

[0012] This invention provides a giant tidal power station. It utilizes an inlet and outlet channel designed between two cofferdams, separated by a partition wall. Several power-generating turbines are arranged in a linear array along the extension direction of the inlet channel on the partition wall. During high tide, the first and second gates are opened, while the third and fourth gates are closed, allowing seawater to flow into the inlet channel through its inlet and into the cofferdam through its outlet. The flow of seawater within the inlet channel drives the turbines to generate electricity. During low tide, the second gate is closed, while the third and fourth gates are opened, allowing seawater to flow into the outlet channel through its inlet and into the sea through its outlet. The flow of seawater within the outlet channel also drives the turbines to generate electricity. This design effectively utilizes the kinetic energy generated by the seawater flow during both high and low tides, thus increasing the power generation capacity. Attached Figure Description

[0015] The technical solution of this utility model will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0016] Please see Figure 1 This utility model provides a technical solution:

[0017] A giant tidal power station includes parallel water inlet channels 101 and drainage channels 201, separated by a partition wall 301. To facilitate tidal energy generation, several power turbines 401 are arranged in a linear array along the extension direction of the water inlet channels 101 on the partition wall 301. During high tide, to facilitate seawater entering the water inlet channels 101 and during low tide, to facilitate seawater discharge from the water inlet channels 101 through the drainage channels 201, both ends of the water inlet channels 101 and 201 are provided with inlets and outlets. During high tide, seawater flows into the water inlet channels 101 through the inlets, and the flow of seawater drives the power turbines 401 to rotate and generate electricity. At low tide, seawater entering the inlet channel 101 flows through the inlet of the outlet channel 201 to the outlet of the outlet channel 201. During this flow, the seawater drives several power generation turbines 401 to rotate and generate electricity. The power generation turbines 401 can be designed with helical blades. Power generation by the rotation of the power generation turbines 401 is existing technology and will not be elaborated upon here. In the actual construction of this giant tidal power station, the length and width of the inlet channel 101 and the outlet channel 201 can be constructed according to the actual power generation capacity, and the number of power generation turbines 401 installed should be adjusted accordingly.

[0018] In order to temporarily store the water entering the inlet channel 101 during high tide, this embodiment also includes two cofferdams 501 that are spaced apart and interconnected. The inlet channel 101 and the drainage channel 201 are both located between the two cofferdams 501. The outlet of the inlet channel 101 and the inlet of the drainage channel 201 are respectively connected to the two cofferdams 501.

[0019] To prevent seawater from flowing into the drainage channel 201 during high tide and into the inlet channel 101 during low tide, in this embodiment, a first gate 601 is installed at the inlet of the inlet channel 101, a second gate 602 is installed at the outlet of the inlet channel 101, a third gate 603 is installed at the inlet of the drainage channel 201, and a fourth gate 604 is installed at the outlet of the drainage channel 201. Each gate can block the corresponding position.

[0020] In actual design, the bottom plane of the water inlet channel 101 and the bottom plane of the drainage channel 201 can be made no higher than the lowest level of the current sea area at low tide, so that the impact of the tide water on the power generation turbine 401 during high tide and low tide can play its maximum role.

[0021] The space within cofferdam 501 can also be used to cultivate economic plants and marine edible animals, thereby improving the economic benefits of this power station. Additionally, cofferdam 501 can be used as a dock if needed.

[0022] Working principle:

[0023] At high tide, the first gate 601 and the second gate 602 are opened, while the third gate 603 and the fourth gate 604 are closed. Seawater can then flow into the intake channel 101 through its inlet and into the cofferdam 501 through its outlet. The flow of seawater within the intake channel 101 drives several power turbines 401 to generate electricity.

[0024] At low tide, the second gate 602 is closed, and the third gate 603 and the fourth gate 604 are opened, allowing seawater to flow into the drainage channel 201 through its inlet and then into the sea through its outlet. The seawater flowing through the drainage channel 201 drives several power generation turbines 401 to rotate and generate electricity.

It should be understood that this utility model is not limited to the forms disclosed herein and should not be construed as excluding other embodiments.
