Description

Technical Field

[0001] The present invention relates to the technical field of deep-sea hydrothermal temperature difference energy power generation, and in particular to a deep-sea hydrothermal temperature difference energy power generation device. Background Art

[0002] Hydrothermal vents gradually form along cracks in the Earth's crust. Seawater seeps downward through these cracks, heated by magma, and then flows upward, erupting, forming deep-sea hydrothermal vents. There are over 150 known deep-sea hydrothermal vents. The hydrothermal fluid, composed of water and some chemicals, erupts at temperatures ranging from 60-350°C, often forming "chimneys" and surrounding areas rich in marine life and mineral resources. Based on the temperature of the hydrothermal fluid and the mineral composition of the erupted fluid, submarine hydrothermal chimneys are generally classified as black chimneys, white chimneys, and low-temperature vents.

[0003] Currently, the power generation equipment that uses seabed hydrothermal fluids in combination with thermoelectric power generation plates includes introducing high-temperature water flow and low-temperature water flow into the power generation equipment, where one side of the thermoelectric power generation plate contacts the high-temperature water flow and the other side of the thermoelectric power generation plate contacts the low-temperature seawater, thereby forming a temperature difference for power generation and storage.

[0004] Currently, hot water is introduced into the power generation equipment, and then discharged directly after passing through the thermoelectric power generation plate. There is still heat in the water source that is not fully utilized and is directly discharged, resulting in a low heat utilization rate.

[0005] Therefore, it is necessary to provide a deep-sea hydrothermal temperature difference energy power generation device to solve the above technical problems. Summary of the Invention

[0049] A thermal insulation plate 4 is installed inside the installation box 1 and is located above the power generation mechanism 7. A high-temperature cavity is formed between the thermal insulation plate 4 and the power generation mechanism 7, and a heat reflow cavity 5 is formed between the upper side of the thermal insulation plate 4 and the installation box 1.

[0050] The installation box 1 is connected to the cooling chamber 2 at both ends thereof with a cold water inlet pipe 8 and a cold water outlet pipe 11;

[0051] A hot water pipe 9 is connected to one end of the installation box 1 located in the high-temperature chamber 3, and a discharge pipe 12 is connected to one end of the installation box 1 located in the hot reflux chamber 5.

[0052] The power generation mechanism 7 includes a fixed plate 71 , on which a plurality of thermoelectric power generation sheets 72 are mounted. Two ends of the thermoelectric power generation sheets 72 are located inside the high-temperature chamber 3 and the cooling chamber 2 , respectively.

[0053] The thermoelectric power generation sheets 72 are arranged in an array on the fixed plate 71. A sealing ring 73 is provided on the side of the thermoelectric power generation sheet 72, and the seal is made of a high-temperature corrosion-resistant material. The sealing ring 73 is provided to improve the sealing performance of the connection between the upper and lower heat-conducting parts of the thermoelectric power generation sheet 72 and the fixed plate 71.

[0054] The thermal insulation board 4 includes a board body 41 , and a thermal insulation layer 42 is provided inside the board body 41 .

[0055] The board 41 is a hard board with poor thermal conductivity, such as a plastic board, etc., wherein the heat insulation layer 42 can be made of heat insulation materials such as vacuum insulation board.

[0056] The hot water pipe 9 includes a water inlet pipe 91 , one end of which is connected to a main pipe 92 , one side of which is connected to a plurality of branch pipes 93 , one end of which is in communication with one end of the high-temperature chamber 3 .

[0057] By providing a plurality of branch pipes 93 , the water flow can be introduced into the interior of the high-temperature chamber 3 more evenly.

[0058] The installation box 1 includes a box body 101 , and a heat insulation cover 102 is connected to the surface of the box body 101 .

[0059] The insulation plate 4 is connected to a heat-conducting mechanism 6, which includes a central shaft 61. The central shaft 61 is installed on the insulation plate 4, and the bottom end of the central shaft 61 is connected to a bottom plate 64. The bottom plate 64 contacts the upper side of the thermoelectric power generation sheet 72. The surfaces of the central shaft 61 and the bottom plate 64 are both covered with a heat-insulating sleeve 65.

[0060] The central shaft 61 , the bottom plate 64 and the arc-shaped piece 63 are all made of metal materials with good thermal conductivity, preferably copper, stainless steel, aluminum and the like.

[0061] A connecting piece 62 is fixedly connected to the upper end of the central shaft 61 and is located inside the heat reflow chamber 5 . A plurality of arc-shaped pieces 63 are connected to the connecting piece 62 .

[0062] By configuring the arc-shaped piece 63 , the contact area with the water flow can be increased, thereby improving the heat conduction efficiency.

[0063] The installation box 1 is connected to an energy storage box 13 .

[0064] The energy storage box 13 is equipped with a battery, a voltage conversion circuit, a charging circuit, etc.

[0065] The working principle of the deep-sea hydrothermal temperature difference energy power generation device provided by the present invention is as follows:

[0066] Hot water flows into the high-temperature chamber 3 through the hot water pipe 9, and low-temperature seawater flows into the cooling chamber 2 through the cold water inlet pipe 8, respectively contacting the upper and lower sides of the thermoelectric power generation sheet 72, thereby generating a temperature difference to generate electricity.

[0067] The cold water is discharged through the cold water outlet pipe 11, and the hot water enters the hot reflux chamber 5 through the return pipe 10;

[0068] When the water enters the front half of the heat reflux chamber 5, the water source temperature is still relatively high. At this time, the water flows through the heat conduction mechanism 6. After the water contacts the arc-shaped sheet 63 and the connecting sheet 62, the heat is transferred to the arc-shaped sheet 63 and the connecting sheet 62. The arc-shaped sheet 63 and the connecting sheet 62 conduct the heat to the central shaft 61. The central shaft 61 conducts the heat to the thermoelectric power generation sheet 72 through the bottom plate 64, so that the heat can be refluxed and reused.

[0069] The surfaces of the central shaft 61 and the bottom plate 64 are both provided with a heat insulating sleeve 65, which can greatly prevent the hot water flow passing through the high temperature chamber 3 from transferring heat to the heat conducting mechanism, and the heat is introduced into the liquid inside the heat reflux chamber 5, resulting in heat loss.

[0070] Similarly, a thermal insulation plate 4 is provided to isolate the high-temperature chamber 3 from the heat reflow chamber 5, thereby preventing the heat in the high-temperature chamber 3 from being introduced into the heat reflow chamber 5;

[0071] The electricity generated is stored in the battery inside the energy storage box 13;

[0072] A heat conducting mechanism 6 is provided, which can block the flow of hot water into the high-temperature chamber 3, reduce the speed of hot water outflow, and prolong the time the hot water stays in the high-temperature chamber 3, that is, prolong the contact time between the hot water and the thermoelectric power generation sheet 72, thereby improving the utilization rate of heat.

[0073] Compared with related technologies, the deep-sea hydrothermal temperature difference energy power generation device provided by the present invention has the following beneficial effects:

[0074] By providing the heat reflux chamber 5, the hot water flow passing through the thermoelectric power generation sheet 72 can be returned to the heat reflux chamber, and the heat transfer mechanism 6 can be used to re-introduce the heat into the thermoelectric power generation sheet 72, so that the heat in the water flow can be more fully utilized.

[0075] The heat conducting mechanism 6 can block and slow down the flow of water, thereby extending the time the water stays in the high-temperature chamber 3, that is, extending the contact time between the hot water and the thermoelectric power generation sheet 72, and improving the utilization rate of heat.

[0079] The diameter of the branch pipe 93 is smaller than that of the main pipe 92 , thereby ensuring the water pressure when the water flows through the branch pipe 93 into the high-temperature chamber. The rotation shaft 142 and the installation cover 141 are mechanically sealed at the penetration point.

[0081] The surface of the rotating rod 144 is provided with a plurality of annular grooves. A connecting ring is provided on the surface of the rotating rod 144 and inside the annular grooves. The annular groove cooperates with the connecting ring to limit the horizontal side of the rotating rod 144. A connecting rod is fixed on the upper side of the connecting ring surface. The upper end of the connecting rod is fixedly connected to the lower side of the insulation plate 4. The water flow driving mechanism 14 is preferably made of a lightweight and high-temperature resistant material.

[0082] When water flows through the branch pipe 93, the water flows, driving the impeller 143 to rotate, driving the impeller 143 to rotate the rotating shaft 142, the rotating shaft 142 drives the driving bevel gear 146 to rotate, the driving bevel gear 146 drives the driven bevel gear 147 to rotate, the driven bevel gear 147 drives the rotating rod 144 to rotate, and the rotating rod 144 drives the driving blades 145 to rotate;

[0083] The driving blades 145 can drive the water flow to rotate and flow, so that the water flow can interact with the thermoelectric power generation sheet 72 more quickly and fully, thereby improving the heat conversion efficiency.

[0084] Each water flow driving mechanism 14 is located in the interval between each adjacent row of thermoelectric power generation sheets 72 , and each branch pipe 93 between each adjacent row of thermoelectric power generation sheets 72 is correspondingly provided with a water flow driving mechanism 14 .
