Description

Technical Field

[0001] A wave power generation device that converts the energy of undulating waves into the pressure potential energy of a liquid circulating in a closed pipe, and then into electrical energy. Background Technology

[0002] Wave energy is a nearly eternal, environmentally friendly, and enormous form of energy in nature. If wave energy can be utilized efficiently, it can greatly alleviate the current energy shortage and reduce environmental pollution caused by non-clean energy sources. Summary of the Invention

[0003] This invention is a wave power generation device that converts the energy of undulating waves into the pressure potential energy of a liquid circulating in a closed pipe within the device, and then into electrical energy. It consists of a hydroelectric power generation device (1), a floating control device (2), an anchor and electrical transmission device (3), and multiple wave energy conversion devices (4), as shown in Figure-1.

[0004] The wave energy conversion device (4) consists of a head connector (41), a tail connector (42), a forward conversion group (43), and a reverse conversion group (44), as shown in Figure 2.

[0005] Both the forward conversion group (43) and the reverse conversion group (44) are composed of multiple basic units (45) and elastic bellows (46), except that the basic units (45) are in opposite directions, as shown in Figure-3.

[0006] The basic unit (45) consists of a cross support beam (451), a simple one-way valve (452), and a floating airbag (453), as shown in Figure 4. The cross support beam (451) consists of a cross beam and a longitudinal beam, with the floating airbag (453) mounted on top. The gas in the floating airbag (453) ensures that the buoyancy of the entire device is much greater than its weight, thus allowing it to float on the water surface and stay close to the water surface. The simple one-way valve (452) is mounted below the cross beam of the cross support beam (451). The simple one-way valve (452) only allows liquid to flow in the direction it passes through.

[0007] Along the passage direction of the simple one-way valve (452), multiple base units (45) are connected in sequence. The two base units (45) are hinged together by the longitudinal beam of the cross support beam (451) to ensure that the two base units (45) can only rotate up and down according to the hinge point, as shown in Figure-5.

[0008] Two simple one-way valves (452) are connected through an elastic bellows (46). The elastic bellows (46) is a hollow pipe that can expand and contract, and is filled with liquid, as shown in Figure 6.

[0009] When the two basic units (45) rotate downwards based on the hinge point of the longitudinal beam, the distance between the two simple one-way valves (452) decreases, compressing the elastic bellows (46). The internal space of the elastic bellows (46) decreases, forcing the liquid to flow forward and backward. The rear simple one-way valve (452-1) closes by moving in the opposite direction to the water flow, while the front simple one-way valve (452-2) opens by moving in the same direction as the water flow. The water flows only through the front simple one-way valve (452-2), forming a forward directional water flow, such as... Figure 7 .

[0010] When the two basic units (45) rotate upward, the distance between the two simple one-way valves (452) increases, stretching the elastic bellows (46). The internal space of the elastic bellows (46) increases, and liquid is drawn in from both ends. The front simple one-way valve (452-2) closes by being opposite to the direction of water flow, and the rear simple one-way valve (452-1) opens by being in the same direction as the direction of water flow. Liquid is drawn in from the rear simple one-way valve (452-1), forming a forward directional water flow, as shown in Figure-8.

[0011] Multiple basic units (45) and an elastic bellows (46) are connected in series, and liquid is filled in the elastic bellows (46). When the multiple basic units (45) rotate upward and downward periodically with the waves, a forward directional water flow can be continuously generated in the elastic bellows (56), such as... Figure 9 .

[0012] Multiple simple one-way valves (452) are sequentially connected through base units (45) with the same direction to form a set of base units (45), called the forward conversion group (43). Simultaneously, a set of base units (45) with the opposite direction to the forward conversion group (43) is assembled, called the reverse conversion group (44), as follows: Figure 10 .

[0013] The forward conversion group (43) and the reverse conversion group (44) are arranged horizontally and hinged together by the crossbeam of the cross support beam (451). The forward conversion group (43) converts the undulating wave energy into a forward unidirectional water flow in the elastic bellows (46), and the reverse conversion group (44) converts the undulating wave energy into a backward unidirectional water flow in the elastic bellows (46). The outlet (431) of the forward conversion group (43) is connected to the inlet (11) of the hydroelectric generator (1), and the outlet (12) of the hydroelectric generator (1) is connected to the inlet (441) of the reverse conversion group (44). The outlet (442) of the reverse conversion group (44) is connected to the inlet (432) of the forward conversion group (43) through the tail connector (42), as shown. Figure 11 .

[0014] The forward conversion group (43), the hydroelectric generator (1), the reverse conversion group (44), and the tail connector (42) form a closed ring, which is filled with liquid in a closed pipe such as the elastic bellows (46). When the whole device rises and falls with the waves, the wave energy of the up-and-down movement is converted into the pressure potential energy of the liquid flowing in the direction of the elastic bellows (46) through the combined action of the floating airbag (453), the cross support beam (451), the simple one-way valve (452), and the elastic bellows (46). The pressure potential energy is then converted into electrical energy through the hydroelectric generator (1).

[0015] In order to maximize the use of wave energy, several wave energy conversion devices (4) can be set up in the horizontal direction. They are hinged through the crossbeam of the cross support beam (451), and the outlet and inlet are connected in parallel through the head connector (41). They are then connected to a hydroelectric generator (1), as shown in Figure-1.

[0016] Meanwhile, a closed diaphragm (47) is laid between all the cross support beams (451) and the floating airbags (453). Through sealing and water tension, the device can follow the fluctuations of the water surface as much as possible and generate corresponding deformation, thereby maximizing the conversion of wave potential energy into the pressure potential energy of the directional circulating liquid in the closed pipes of the device, thereby generating more electrical energy.

[0017] In the event of severe weather, the gas in the floating airbag (453) can be released by the floating control device (2) to allow the entire equipment to sink below the water surface, thus avoiding damage to the equipment caused by severe weather. After the weather improves, the gas is then injected into the floating airbag (453) to allow the entire equipment to float on the water surface and continue generating electricity.

[0018] The entire device is anchored to a body of water or sea by means of an anchor and an electrical transmission device (3), and the generated electrical energy is transmitted out. Attached Figure Description
