Problems solved by technology
[0003] The traditional one-storage bidirectional tidal power station generally uses bidirectional tubular turbines, which are generally equipped with S-shaped runner blades to meet the needs of bidirectional power generation; however, the design and The manufacturing requirements are relatively high, especially the waterproofing of the bulb body and the design of the S-shaped blades, which put forward high requirements for the investment of the power station

Embodiment Construction
[0023] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0024] A tidal power generation device of the present invention, such as figure 1 As shown, it includes two gate valve mechanisms with the same structure and oppositely arranged. A hydraulic conversion mechanism is arranged between the two gate valve mechanisms, and the distance between the hydraulic conversion mechanism and the two gate valve mechanisms is equal. The hydraulic conversion mechanism is connected to the generator through the transmission mechanism. 13.
[0025] There are also two baffles a1 between the two gate valve mechanisms. The two gate valve mechanisms and the baffle a1 form a chamber 2. During the operation, the baffle a1 can effectively prevent the water from mixing into other flow channels and cause unstable flow. ; The hydraulic conversion mechanism is located in the chamber 2.
[0026] Each gate valve mechanism inc...

The invention discloses a tidal power generation device, which comprises two opposite gate valve mechanisms identical in structure. A hydraulic power conversion mechanism is arranged between the two gate valve mechanisms, distances between the hydraulic power conversion mechanism and the two gate valve mechanisms are equal, and the hydraulic power conversion mechanism is connected with a power generator through a transmission mechanism. Compared with a traditional bulb type and shaft extension type power generating devices, the tidal power generation device has advantages that by arrangement of the power generator outside a flow passage, problems of airtightness and damp resistance of the power generator are out of consideration; since water flow passages formed by gates and flow passagesare straight flow passages, flow loss of water flow in the flow passages can be reduced.
Description
technical field [0001] The invention belongs to the technical field of tidal power generation devices, and relates to a tidal power generation device. Background technique [0002] As a part of my country's new energy strategy, the development and utilization of tidal energy is getting more and more attention in today's power energy shortage. my country's long coastline provides abundant site selection conditions for the development of tidal energy, and the excellent geological environment has led to the emergence of various tidal power generation methods in recent years. Among the various tidal energy power generation methods, one-storage two-way power generation is currently the most economical and effective power generation method. The so-called one-reservoir two-way power generation refers to the construction of a reservoir along the coastline. When the tide is high, the seawater flows into the reservoir from the sea and drives the hydroelectric generating set to genera...
