Description

A device for capturing wave energy

technical field

The invention relates to the technical field of ocean wave energy utilization, in particular to a wave energy capture device.

Background technique

With the development and progress of human society, the environmental pollution and energy crisis caused by the massive consumption of fossil fuels and the depletion of traditional energy sources have become increasingly severe. People urgently need to seek a clean and pollution-free green renewable energy to replace traditional energy. There is huge energy in the vast ocean, among which wave energy is the highest grade and most widely distributed renewable clean energy in ocean energy. If wave energy can be efficiently converted and utilized, the survivability of the device can be improved, and the cost of the device can be reduced, it is expected to achieve large-scale commercial application and effectively alleviate or even solve the environmental pollution and energy crisis caused by the consumption of traditional fossil fuels. It is of great significance to study a wave energy harvesting device with high working efficiency.

Such a wave energy utilization system is disclosed in the patent document with publication number CN104196673A titled "A Wave Energy Power Generation System". The system includes a wave energy conversion device and a wave energy collection device. The wave energy conversion device includes a supporting floating body, a power generation platform above the floating body, a runner, a gear, a gearbox and a generator; the wave energy collecting device includes a wave energy collecting floating body and a pillar structure built in the supporting floating body. The system captures wave energy by using the relative motion between the wave energy harvesting floating body and the supporting floating body, and drives the generator to generate electricity through a series of mechanical transmissions. Because this system involves mechanical components such as gears, runners, cranks, gearboxes, and rotating shafts, the structure is relatively complicated, and the reliability and durability are relatively poor.

In the patent document with the publication number CN103939271A and titled "Combined Oscillating Float Wave Energy Generating Device", a combined oscillating buoy wave energy generating device is disclosed, which mainly includes a power generation system and a fixed system. Among them, the fixed submersible floating body, fixed frame and working platform constitute the fixed system, and the float, hydraulic motor, hydraulic transmission mechanism and generator constitute the power generation system. The device utilizes the back-and-forth oscillation of the float along the vertical guide rod to drive the hydraulic transmission mechanism to generate electricity. Because the float of the device can only do heaving motion due to the constraint of the vertical guide rod, the wave energy capture performance will be restricted. And the shape of the submersible floating body of the device is huge, the construction cost is relatively high, and it bears a large hydrodynamic effect, so the stability is poor.

The hydraulic energy application module 5 of the present invention has the following two implementations:

Option 1: The hydraulic energy application module 5 is a hydraulic power generation circuit.

As shown in Figure 14, when the hydraulic energy application module 5 is used for power generation, the hydraulic energy application module 5 mainly consists of a high-voltage energy storage regulator 51, a low-voltage energy storage regulator 52, a hydraulic motor 53 and a first The generator set 54 constitutes. The high-pressure outlet pipe 48 communicates with the high-pressure energy storage regulator 51 , while the low-pressure inlet pipe 46 communicates with the low-pressure energy storage regulator 52 . A hydraulic motor 53 is provided on the communication pipeline between the high pressure energy storage regulator 51 and the low pressure energy storage regulator 52 . The hydraulic motor 53 is connected with the first generator set 54 . The fluid in this hydraulic power generation circuit scheme is hydraulic oil.

Scheme 2: The hydraulic energy application module 5 is a seawater desalination system.

As shown in FIG. 15 , when the hydraulic energy application module 5 is used for seawater desalination, the hydraulic energy application module 5 mainly consists of a water suction pipe 55 , a filter 56 , a pressure regulator 57 and a membrane assembly 58 . One end of the water suction pipe 55 protrudes from the hydraulic energy application module 5 to communicate with seawater, and the other end is connected to the low-pressure inflow pipe 46 through a filter 56 . The high-pressure outlet pipe 48 communicates with the pressure regulator 57 and the membrane assembly 58 in sequence. The membrane module 58 is respectively connected to a fresh water production pipe 59 and a brine drainage pipe 59'. In this seawater desalination system scheme, the fluid flowing into the hydraulic energy application module 5 is natural seawater, and the fluid flowing out is fresh water and concentrated brine.

In the present invention, several low-pressure inlet pipes 46 and high-pressure outlet pipes 48 protruding from several rod-type hydraulic cylinders 4 can be connected in parallel to share the same hydraulic energy application module 5 .

The use process of the present invention is illustrated below:

During the installation of the device or the consignment process when it is docked for maintenance, the counterweight cavity 3 is not filled with counterweights to facilitate the shipment of the device. When the device is working normally, the counterweight cavity 3 is filled with seawater or sand is placed for counterweight, so that the center of gravity of the device is close to the bottom, and the stability of the device is improved.

When the wave 81 passes by, it will drive a number of floats 2 to swing up and down relative to the main cavity 1 , and drive the hydraulic rod 43 to perform linear reciprocating motion in the rod hydraulic cylinder 4 . The second check valve 45 only allows fluid to flow into the rod hydraulic cylinder 4 through the low pressure inlet pipe 46 , and the first check valve 47 only allows fluid to flow out from the rod hydraulic cylinder 4 through the high pressure outlet pipe 48 . When the float 2 swings downward, the hydraulic rod 43 moves away from the rod-type hydraulic cylinder 4, and a negative pressure is formed in the rod-type hydraulic cylinder 4; when the float 2 swings upward, the hydraulic rod 43 is pressed into the rod-type hydraulic cylinder 4 The movement will form high pressure in the rod hydraulic cylinder 4.

The pressure difference between the high pressure energy storage regulator 51 and the low pressure energy storage regulator 52 will drive the hydraulic oil from the high pressure energy storage regulator 51 to flow into the low pressure energy storage regulator 52, drive the hydraulic motor 53 to move, and drive the first A generator set 54 generates electricity.

When the hydraulic energy application module 5 of the present invention adopts the scheme of the seawater desalination system, the negative pressure formed in the rod hydraulic cylinder 4 will suck the seawater from the ocean into the water suction pipe 55, and then flow through the filter 56 and the low-pressure inflow pipe 46 in sequence. And the second one-way valve 45 enters in the rod hydraulic cylinder 4 . The high pressure formed in the rod-type hydraulic cylinder 4 will pump the seawater in the rod-type hydraulic cylinder 4 into the pressure regulator 57 through the first check valve 47 and the high-pressure outlet pipe 48. After depressurization, the seawater is pumped into the membrane module 58 to desalinate the seawater, and the produced fresh water flows out through the fresh water output pipe 59, while the concentrated brine produced in the process of preparing fresh water is discharged back into the sea through the concentrated brine discharge pipe 59'.
