Description

Technical Field

[0001] The invention relates to the field of marine science and energy technology, and in particular to a deep-sea water lifting device utilizing wave energy. Background Art

[0002] The oceans that can carry out photosynthesis are mainly in the surface layer. It is generally difficult to carry out photosynthesis in the sea areas below 200m. Since the surface water is heated by sunlight and its density decreases, it is mainly located in the upper layer. The bottom water of the ocean mainly comes from high latitudes and carries a large amount of nutrients. However, due to the stratification of seawater, it is generally difficult for the bottom water to enter the surface layer to participate in photosynthesis. At the same time, due to the existence of the thermocline, the rise of the bottom seawater is hindered, making the surface seawater oligotrophic, which is not conducive to the growth of algae and restricts the development of fishery resources. Therefore, lifting the bottom water to the surface can greatly promote the productivity of the surface layer, and then promote the production of fisheries.

[0003] Lifting the bottom water of the ocean to the surface is also called creating artificial upwelling. At present, the bottom seawater is mainly lifted by artificial gas injection to create upwelling. This method can be carried out in some harbor areas with good sea conditions, but it is difficult to use it in offshore areas with bad sea conditions. In addition, it takes a lot of energy to inject gas into the seabed. At the same time, personnel are required to be on duty on the gas injection platform, and it is difficult for personnel to work at sea for a long time far away from the mainland.

[0004] Therefore, there is an urgent need for a new deep-sea water lifting device that utilizes wave energy to solve the above problems. Summary of the invention

[0005] The purpose of the present invention is to provide a deep-sea water lifting device that utilizes wave energy, which can lift the bottom water of the ocean to the surface with the help of waves, without the need for additional energy supply, and does not require human supervision after being deployed on the seabed. It can also be deployed in offshore waters with poor sea conditions.

[0008] The barrel body is provided with a water channel running vertically along the axial direction;

[0009] A floating body is arranged on the outer wall of the upper part of the barrel body;

[0010] A one-way valve is arranged at the bottom opening of the water channel;

[0011] The counterweight mechanism comprises a connecting assembly and a counterweight block, wherein the barrel body is rotatably connected to a first end of the connecting assembly, and the counterweight block is connected to a second end of the connecting assembly.

[0012] As a preferred solution, the connecting assembly includes a rotating ring and a cable, the barrel body is rotatably inserted into the rotating ring, one end of the cable is connected to the rotating ring, and the other end is connected to the counterweight.

[0013] As a preferred solution, the inner diameter of the rotating ring is larger than the outer diameter of the barrel body.

[0024] The deep ocean water lifting device utilizing wave energy provided by the present invention is equipped with a float and a counterweight mechanism on a barrel body.

[0033] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] Embodiment 1

[0035] like Figure 1 As shown, this embodiment provides a deep-sea water lifting device utilizing wave energy, including a barrel 1, a float 2, a one-way valve 3 and a counterweight mechanism 4. The barrel 1 is provided with a water channel that runs up and down along the axial direction. The float 2 is arranged on the outer wall of the upper part of the barrel 1. The one-way valve 3 is arranged at the bottom opening of the water channel. The counterweight mechanism 4 includes a connecting assembly and a counterweight block 41, the barrel 1 is rotatably connected to the first end of the connecting assembly, and the counterweight block 41 is connected to the second end of the connecting assembly.

[0036] The deep-sea water lifting device using wave energy provided in this embodiment uses the up and down movement of waves to provide energy. Since the seawater mainly moves up and down in situ when it moves in waves, a float 2 and a counterweight mechanism 4 are installed on the barrel body 1. The buoyancy provided by the float 2 changes through the up and down movement of the waves, thereby causing the device to move up and down to obtain energy.

[0037] The deep-sea water lifting device utilizing wave energy provided in the present embodiment is provided with a water channel which runs through from top to bottom on the barrel body 1, and a one-way valve 3 is provided at the bottom of the water channel, so that water can enter the water channel from the bottom and will not flow downward again; by providing a float 2 on the outer wall of the upper part of the barrel body 1, the upper part of the barrel body 1 can be slightly floated out of the water; the barrel body 1 is rotatably connected to the first end of the connecting assembly, and the counterweight block 41 is connected to the second end of the connecting assembly, which is beneficial for preventing the barrel body 1 from being entangled when circling around the counterweight block 41 under the action of external force, and the connection position between the first end of the connecting assembly and the barrel body 1 can be appropriately adjusted to ensure that the resultant force of the lateral force on the lower part of the barrel body 1 is much greater than the lateral force on the upper part of the barrel body 1 caused by wind and waves, etc., to ensure that the barrel body 1 is in an upright state in the sea water.

[0038] The deep-sea water lifting device using wave energy provided in this embodiment, when in use, firstly, according to the structure of the device itself and the conditions of the sea area where it is located, the connection position between the first end of the connecting assembly and the barrel body 1 is appropriately adjusted, so that the lateral force acting on the device is basically in a balanced state. Therefore, the horizontal force is temporarily not considered. The movement of the device in seawater is mainly affected by the vertical force, and its vertical force is mainly composed of buoyancy and gravity. The buoyancy is mainly provided by the device itself and the floating body 2, and the gravity is mainly composed of the counterweight block 41 and the weight of the device itself. Under the action of waves, the device will Figure 2 As shown, the device moves up and down, and position A is the crest of the wave. The device is in the top equilibrium state at this position, and the gravity G and the buoyancy F are balanced. When the wave changes from the crest to the trough, since the top floating body 2 is exposed to the water surface, G>F, the device will overcome the resistance under the action of gravity and move downward to position B. The wave continues to change to the trough and finally reaches the bottom position C, where the device reaches the lowest point equilibrium state. Afterwards, as the wave action begins to change from the trough to the crest, more floating bodies 2 are submerged by seawater. At this time, F>G, the device will overcome the resistance and move upward under the action of buoyancy to position D. As the wave rises further, it finally returns to position A. From A to C, the one-way valve 3 will open due to the action of the water flow, so that the bottom seawater enters the barrel 1, and the top seawater will overflow, returning from position C to position A. Since the one-way valve 3 is closed, the seawater in the barrel 1 will be lifted under the action of buoyancy. After multiple reciprocating movements, the bottom water will be lifted to the surface.

[0039] The deep ocean water lifting device using wave energy provided in this embodiment can lift the bottom ocean water to the surface with the help of waves, without the need for additional energy supply, and without the need for personnel to be on duty after being deployed on the seabed. It can also be deployed in offshore waters with poor sea conditions.

[0043] Preferably, the inner diameter of the rotating ring 42 is larger than the outer diameter of the barrel body 1 , so that the barrel body 1 can rotate in the rotating ring 42 .

[0044] Preferably, an overflow hole 11 is provided at the upper portion of the barrel body 1, and the seawater in the water channel can flow out through the overflow hole 11. The overflow hole 11 is provided to facilitate the discharge of the seawater in the barrel body 1. Further, the overflow hole 11 is located below the float 2.

[0045] In this embodiment, overflow holes 11 are provided on both sides of the barrel body 1. Of course, in other embodiments, the arrangement of the overflow holes 11 can be adjusted according to actual needs, for example, a plurality of overflow holes 11 are arranged at intervals along the entire circumference of the barrel body 1.

[0046] The deep-sea water lifting device using wave energy provided in this embodiment further includes a water collecting plate 5, which is connected to the edge of the bottom of the barrel 1. By providing the water collecting plate 5, it is beneficial to allow more seawater to enter the water channel when the barrel 1 descends. The area of ​​the water collecting plate 5 is moderately adjustable, so as to ensure that more seawater enters while its resistance is not too large, so as to ensure that the barrel 1 can float smoothly.

[0047] Preferably, the water collecting plate 5 is open with its opening facing downward, so that more seawater can enter the water channel from the bottom of the drum 1.

[0048] In this embodiment, the floating body 2 is arranged along the circumference of the barrel 1. Of course, in other embodiments, the arrangement of the floating body 2 can be adjusted according to the structure of the device itself and the conditions of the sea area where it is located, for example, the floating body 2 is arranged on both sides of the barrel 1.
