Embodiment 1

[0054] (1) The solution to technical problems of this tidal power station is (see figure 1 )

[0055] The power station mainly has two reservoirs (upper reservoir 61 and lower reservoir 62), a water diversion pipe 7, three sluice gates, a hydroelectric generator unit 8, a water pump group (A pump 31) and a B water pump group (B pump 32) .

[0056] A, lower reservoir 62: in the gulf or estuary that has tide, build a water-retaining embankment, separate the estuary by sea or gulf from the sea, form a natural reservoir (named lower reservoir). Use a water pump to drain the seawater in the reservoir to measure the depth of the reservoir. If the depth is not enough, use an excavator to dig to the required depth, and repair the cement platform in the reservoir and install a water pump (B pump 32). The characteristic is that the water outlet of the water pump is lower than the zero water level. (See image 3 ), controlled by the third gate 53.

[0057] The structural characterist...

example

[0111] Calculation example: a tidal power station with an average tidal range of 2 meters X=4, h=1, H 1 = 7, then

[0112] f 7 =0.8×10 6 h 2 1 S=0.8×10 6 ×7 2 S=39.2×10 6 S (annual power generation of tidal power station)

[0113] 1.25F 5 =1.25×0.8×10 6 (X+h) 2 S=1.25×0.8×10 6 ×(4+1) 2 S=25×10 6 S (annual electricity consumption for pumping water)

[0114] f 2 =F 7 -1.25F 5 =39.2×10 6 S-25×10 6 S=14.2×10 6 S (net annual power generation)

[0115] B: Water level difference power generation in upper reservoir manufacturing

[0116] Create water level difference: In order to make full use of tidal energy to generate electricity and increase power generation, the feature is to increase the height of the dam on the upper reservoir, and at the same time build a cement platform on the beach next to the upper reservoir and install a water pump (A pump). When the wave peaks, the seawater is pumped into the upper reservoir to increase the water level of the upper...

Abstract

The invention discloses a one-way tidal power station capable of increasing water level difference and continuously generating power and a power generation method, and relates to the technical field of tidal energy utilization. The tidal power station comprises an upper reservoir, a lower reservoir and a hydraulic generator set, wherein the lower reservoir is constructed at a bay or a river mouthwith tide and is used for separating the bay or the river mouth from the sea; a pump B is mounted in the lower reservoir, and a water outlet of the pump B is controlled through a gate C; the upper reservoir is constructed on a beach beside the lower reservoir; two water gates are constructed at the upper reservoir; the upper reservoir communicates with the sea through a gate A; a water division pipe is mounted between a gate B and the lower reservoir, so that the upper reservoir communicates with the lower reservoir; and the water division pipe communicates with the upper part of the hydraulicgenerator set, and the lower part of the hydraulic generator set communicates with the lower reservoir to realize power generation. According to the tidal power station, the method of increasing thewater level difference of the upper reservoir and the lower reservoir and synchronously generating power through a plurality of sets is adopted, so that the tidal power station is capable of continuously generating power round the clock; and the power generation capacity of the tidal power stations with different tidal difference can be improved by more than 100 times.

Description

technical field [0001] Tidal energy is a clean and pollution-free environment, which does not affect the ecological balance of renewable energy. The invention relates to the technical field of tidal energy utilization, more specifically, to a one-way tidal power station and a power generation method for increasing water level difference to continuously generate power. Background technique [0002] The sea has two high tides and two low tides every day. The daily tide is the tide, and the night tide is the tide. The huge energy generated during the tidal fluctuation is called tidal energy. At present, there are few tidal energy developments in the world, because the tidal energy utilization rate of tidal power generation is very low, and the single-storage and one-way tidal power station generates power for 10-12 hours a day. The single-storage bidirectional tidal power station generates power for 16-20 hours a day. The power generation is discontinuous, the power generation...
