Problems solved by technology

[0004] At present, the water hammer pump needs to be driven by a motor and generally has only one power tube, so it can only use one-way water level difference, which is not suitable for the characteristics of coastal tidal cycle changes

Embodiment 1

[0018] The present invention provides a tidal energy system utilizing the water hammer effect bidirectionally, such as figure 1 , 2 As shown in , 3, the construction of the dam body has regions and sea areas with variable tidal cycles along the coast, and the dam body is divided into 15 inside the dam body and 16 outside the dam body according to the blocking water body, wherein the offshore side is 16 outside the dam body, and 15 inside the dam body Direction to the dam body is provided with a first water inlet pipe 3, one end of the first water inlet pipe 3 is connected to the inside of the dam body, and the other end is connected to the water hammer chamber 1, and one end of the first water inlet pipe 3 is connected to the inside of the dam body higher than the One end connected to the water hammer chamber 1 forms a drop. A first water inlet valve 4 is provided between the water hammer chamber 1 and the first water inlet pipe 3. The water hammer chamber 1 is provided with a...

Embodiment 2

[0024] On the basis of Example 1, such as Figure 4 , 5 The lengths of the first water inlet pipe 3 and the second water inlet pipe 11 shown are adjusted according to the angle at which the dam body is connected to the water hammer chamber 1 . In order to adjust the length of the first water inlet pipe 3 and the second water inlet pipe 11 and increase the acceleration distance of the water inlet flow, the included angle between the first water inlet pipe 3 and the second water inlet pipe 11 and the water hammer chamber 1 during erection can be changed, The smaller the included angle is, the longer the lengths of the first water inlet pipe 3 and the second water inlet pipe 11 are, and the longer the acceleration distance of the water flow is.

Abstract

The invention relates to the field of tidal energy systems, particularly relates to a system, which forms a water hammer effect by using tidal energy so as to store energy, and discloses a tidal energy system capable of bidirectionally utilizing the water hammer effect. The tidal energy system comprises an embankment body inner side (15), an embankment body outer side (16), a high-pressure water lifting pipe (2), a first water inlet pipe (3), a first water inlet valve (4), a first water outlet pipe (5), a first water outlet valve (6), a first quick valve (7), a second quick valve (8), a second water outlet valve (9), a second water outlet pipe (10), a second water inlet valve (11), a second water inlet pipe (12), a one-way valve (13), an energy storage tank (14) and a water hammer chamber (1). According to the tidal energy system, natural tidal energy is converted into potential energy of high-pressure water through the water hammer effect, and the potential energy is stored in the energy storage tank; the condition that the water hammer effect is initiated by the potential energy of positive-negative water level difference is realized according to the drop height change of tide rise, so that the wind wave resisting capability is improved; due to an inclined water inlet pipe design, relatively long water inlet pipes can be arranged inside relatively narrow embankments.

Description

technical field [0001] The invention belongs to the field of tidal energy devices, and relates to a tidal energy system that uses water level drop in two directions without energy consumption to form a water hammer effect to generate energy and store it. Background technique [0002] At present, the device that utilizes the water hammer effect is the water hammer pump, which uses flowing water as the power, and the valve of the power water pipe is closed instantly through the mechanical action of the motor, which produces a water hammer effect and converts low water head energy into high water head energy. device. [0003] It is generally used in some small water conservancy projects such as rivers and mountain streams, mainly for agricultural irrigation. At present, there are no development examples of applying water hammer pumps to coastal tidal energy. [0004] At present, the water hammer pump needs to be driven by a motor and generally has only one power tube, so it c...
