[0029] To further understand the content of this invention, a detailed description of the invention will be provided in conjunction with the accompanying drawings and embodiments. It should be understood that the embodiments are merely illustrative and not limiting of the invention.

[0030] The following is in conjunction with the appendix Figures 1-7 The present invention will be described in further detail below.

[0031] This invention discloses an offshore wind power energy storage device.

[0032] Reference Figure 1 and Figure 2 As shown, an offshore wind power energy storage device in this embodiment includes an energy storage component and a housing 100 for placing the energy storage component. On opposite sides of the housing 100, there are heat dissipation components 110 for dissipating heat from the housing 100 and pumping components 120 that cooperate with the corresponding heat dissipation components 110.

[0033] The heat dissipation assembly 110 includes a housing 111 located on the outside of the box 100. The housing 111 has a heat dissipation cavity 201 with an opening facing the corresponding side wall of the box 100. The heat dissipation cavity 201 is provided with heat-conducting fins 202 connected to the corresponding side wall of the box 100. The water pumping assembly 120 is used to pump seawater into the heat dissipation cavity 201 to rinse the heat-conducting fins 202. The housing 111 is provided with a heat exchange assembly 130 at intervals for exchanging heat with the seawater flowing in the heat dissipation cavity 201.

[0034] In this embodiment, the energy storage component is used to store the electrical energy generated by the offshore wind power system. Its structure is existing technology and will not be described in detail here. The enclosure 100 allows the energy storage component to be installed inside the enclosure 100, which protects it from being damaged by waves when installed on the floating foundation platform.

[0035] The housing 111, heat dissipation cavity 201 and heat conduction plate 202 are arranged so that the heat conduction plate 202 can conduct heat to the box 100, thereby enabling the heat dissipation component 110 to dissipate heat from the box 100.

[0036] The water pumping component 120 is designed to pump seawater into the heat dissipation component 110, allowing the seawater to flow downwards in the heat dissipation chamber 201 to wash and dissipate heat from the heat-conducting fins 202. This enhances the heat dissipation effect of the heat dissipation component 110, ensuring that the energy storage component placed in the housing 100 is cooled and preventing the energy storage component from overheating and being damaged during prolonged operation.

[0037] In actual use, the lower end of the heat dissipation cavity 201 is open, allowing seawater to flow downwards within the heat dissipation cavity 201 and be discharged through the lower end of the heat dissipation cavity 201.

[0038] In this embodiment, the heat exchange component 130 is configured to cool the seawater flowing downward in the heat dissipation cavity 201, thereby ensuring that the temperature of the seawater used to wash and dissipate heat to the heat-conducting plate 202 located below the heat dissipation cavity 201 is low, and making the heat dissipation effect of the heat dissipation component 110 on the box 100 from top to bottom more uniform.

[0039] Combination Figure 3 As shown, in this embodiment, the heat dissipation cavity 201 is provided with heat dissipation blocks 310 fixed to the corresponding side walls of the box body 100 at intervals along the vertical direction. The heat dissipation block 310 is provided with a cavity 311 with an opening facing the box body 100. The corresponding side wall of the box body 100 is provided with a vent hole (not shown in the figure) communicating with the corresponding cavity 311. The opposite side wall of the heat dissipation cavity 201 is provided with a heat dissipation hole 312 communicating with the corresponding cavity 311. The upper side of the heat dissipation block 310 is inclined. The heat-conducting plate 202 is evenly distributed on the upper side of the heat dissipation block 310. The side wall of the heat dissipation cavity 201 away from the box body 100 is provided with a guide plate 320 for guiding seawater to the heat-conducting plate 202 below it.

[0040] In this embodiment, the arrangement of heat sink 310, cavity 311, vent hole and heat dissipation hole 312 allows the vent hole to connect the box 100 and the corresponding cavity 311, so that the airflow inside the box 100 can flow out or in through the vent hole and the heat dissipation hole 312. This better enables the heat dissipation component 110 to achieve airflow between the box 100 and the outside air, thereby improving the heat dissipation effect of the heat dissipation component 110.

[0041] Since the upper side of the heat sink 310 is inclined and the heat-conducting plates 202 are spaced apart on the upper side of the corresponding heat sink 310, the heat sink 310 can guide the seawater that is being washed on the heat-conducting plates 202 above it, so that the seawater is guided to the corresponding guide plate 320. Through the guiding action of the guide plate 320, the seawater can be washed onto the heat-conducting plates 202 below the heat sink 310, thereby promoting the cooperation between the seawater entering the heat dissipation cavity 201 and the heat-conducting plates 202 at the corresponding positions, ensuring the heat dissipation effect of the heat dissipation component 110.

[0042] Combination Figure 3 As shown, in this embodiment, the cavity 311 is provided with a rotatable rotating rod 330, and the two ends of the rotating rod 330 are provided with fans 331 for blowing air out of the cavity 311 through the heat dissipation holes 312. The heat dissipation cavity 201 is provided with a first driving component for driving the rotating rod 330 to rotate.

[0043] Through the structure in this embodiment, the first drive component can drive the rotating rod 330 to rotate and drive the fan 331 to work, which preferably blows the air in the cavity 311 out through the heat dissipation hole 312, further enhancing the air flow effect in the housing 100 and improving the heat dissipation effect of the heat dissipation component 110.

[0044] Combination Figure 4 and Figure 5 As shown, in this embodiment, the first driving component includes a first rotating shaft 340 rotatably disposed between the corresponding guide plate 320 and the heat sink 310. The first rotating shaft 340 is uniformly provided with driving plates 341 for cooperating with the seawater flowing with the guide plate 320 to drive the first rotating shaft 340 to rotate. Both ends of the first rotating shaft 340 extend out of the housing 111. A first transmission wheel 511 is provided at both ends of the first rotating shaft 340. Both ends of the rotating rod 330 extend out of the housing 111. A second transmission wheel is provided at both ends of the rotating rod 330. A first transmission belt 512 is sleeved between the corresponding first transmission wheel 511 and the second transmission wheel.

[0045] With the structure in this embodiment, the seawater flowing in the heat dissipation cavity 201 can drive the drive plate 341 to rotate the corresponding first rotating shaft 340 when it reaches the corresponding guide plate 320. The arrangement of the first transmission wheel 511, the second transmission wheel and the first transmission belt 512 enables the rotation of the first rotating shaft 340 to drive the rotation of the rotating rod 330, thereby better realizing that the seawater flowing in the heat dissipation cavity 201 drives the rotating rod 330 to rotate the fan 331 and promotes the heat dissipation effect of the heat dissipation component 110.

[0046] Reference Figure 1 and Figure 2 As shown, in this embodiment, the water pumping assembly 120 includes a water pumping pipe 121 arranged in the vertical direction. A rotatable second rotating shaft 210 is provided inside the water pumping pipe 121. A hose 122 extending into the sea is connected to the lower end of the water pumping pipe 121. An impeller 211 for drawing seawater into the water pumping pipe 121 through the hose 122 is provided on the second rotating shaft 210. A water storage pipe 220 for injecting seawater into the heat dissipation cavity 201 is provided above the housing 111. The water storage pipe 220 is connected to the water pumping pipe 121 through a connecting pipe 221. A second driving assembly for driving the second rotating shaft 210 to rotate is provided on the housing 100.

[0047] With the structure in this embodiment, since the hose 122 extends into the sea, the second rotating shaft 210 rotates, causing the impeller 211 to rotate, which generates negative pressure in the pumping pipe 121, and seawater can be drawn into the pumping pipe 121 through the hose 122, thus realizing the pumping assembly 120 to draw seawater.

[0048] In actual use, the water storage pipe 220 is connected to the top of the shell 111 along the width direction of the box 100. It is connected to the water pumping pipe 121 through the connecting pipe 221, so that the seawater pumped in the water pumping pipe 121 can enter the water storage pipe 220. Spray holes are arranged on the water storage pipe 220 along its length direction. The spray holes are used to spray the seawater evenly into the heat dissipation cavity 201, so that the heat conducting fins 202 inside can be better rinsed and dissipated.

[0049] The second drive component is configured to drive the second rotating shaft 210 to rotate, thereby enabling the pumping operation of the pumping component 120.

[0050] In actual use, the second drive component includes a wind speed cup 410 mounted on the second rotating shaft 210, which is driven by the sea breeze to rotate the second rotating shaft 210, thereby enabling the pumping component 120 to work, making the pumping component 120 more energy-efficient and environmentally friendly.

[0051] The second drive assembly also includes a motor assembly (not shown in the figure) for driving the second rotating shaft 210 to rotate, so that when the wind speed cup 410 is not working, the motor assembly can ensure the rotation of the second rotating shaft 210, so that the pumping assembly 120 can work.

[0052] Combination Figure 3 As shown, in this embodiment, the heat dissipation cavity 201 has a slot 351 located above the corresponding guide plate 320 on the side wall away from the housing 100; the heat exchange assembly 130 includes a heat exchange block 360 located at the corresponding slot 351, the heat exchange block 360 has a water storage cavity 361 for storing seawater, the bottom of the water storage cavity 361 has a flow channel 362 communicating with the corresponding slot 351, the water storage cavity 361 has a liftable block 370, the lifting and lowering of the block 370 is used to realize the opening and closing of the flow channel 362, and the heat exchange block 360 is provided with a third driving assembly for driving the lifting and lowering of the block 370.

[0053] Through the structure in this embodiment, the movement of the block 370 within the water storage cavity 361 enables the opening and closing of the flow channel 362. This allows the seawater in the water storage cavity 361 to flow from the flow channel 362 through the slot 351 to the corresponding guide plate 320. Consequently, the seawater that is washed from the heat dissipation cavity 201 to the guide plate 320 can mix with the seawater flowing from the heat exchange component 130 onto the guide plate 320. This better ensures that the temperature of the seawater washed onto the heat-conducting sheet 202 below the guide plate 320 is low, thereby better improving the heat dissipation effect of the heat dissipation component 110.

[0054] In actual use, the heat exchange block 360 is connected to the water pumping pipe 121 and the water storage chamber 361 through a conduit, so that the water pumping component 120 can supply water to the water storage chamber 361. The third drive component is set to better realize the intermittent lifting and lowering of the block 370 in the water storage chamber 361, thereby allowing the heat exchange component 130 to discharge water to the corresponding guide plate 320 at intervals. This better ensures that the water pumping pipe 121 supplies water to the water storage pipe 220 first, and ensures that seawater flows downward in the heat dissipation chamber 201 to rinse and dissipate heat from the heat conduction plate 202.

[0055] Combination Figure 5-7 As shown, in this embodiment, the block 370 is symmetrically provided with uprights 371 extending out of the heat exchange block 360. The uprights 371 are fitted with springs 372 for driving the block 370 to move down to close the flow channel 362. The ends of the uprights 371 extending out of the heat exchange block 360 are connected by connecting plates 373. The third driving assembly includes support plates 520 located at both ends of the heat exchange block 360. The support plates 520 are provided with rotatable cams 710. The connecting plates 373 are provided with push rods 720 for cooperating with the corresponding cams 710 to drive the connecting plates 373 to rise and fall.

[0056] Through the structure in this embodiment, the rotation of the cam 710 can drive the connecting plate 373 to rise and fall at intervals, thereby better realizing the interval rise and fall of the block 370 in the water storage chamber 361, and realizing the interval water output of the heat exchange component 130.

[0057] In this embodiment, a third rotating shaft 521 connected to the cam 710 is provided on one side of the support plate 520. A third transmission wheel 522 is provided on the third rotating shaft 521, and a fourth transmission wheel is provided on the rotating rod 330. A second transmission belt 523 is sleeved between the corresponding third transmission wheel 522 and the fourth transmission wheel.

[0058] Through the structure in this embodiment, the rotation of the rotating rod 330 can drive the third rotating shaft 521 to rotate, which in turn drives the cam 710 to rotate. This allows the heat exchange component 130 to intermittently discharge water by utilizing the flow of seawater in the heat dissipation cavity 201. In this way, the downward flow of seawater in the heat dissipation cavity 201 can drive the fan 331 to work, further improving the heat dissipation effect of the heat dissipation component 110, and can also drive the heat exchange component 130 to intermittently discharge water, which mixes with the seawater flowing in the heat dissipation cavity 201, reducing the temperature of the seawater and further improving the heat dissipation effect of the heat dissipation component 110.

[0059] In this embodiment, the water pumping pipe 121 is installed on the corresponding housing 111 via the mounting component 140.

[0060] In this embodiment, the vertical installation of the water pumping pipe 121 can be better achieved by the mounting component 140. The mounting component 140 can be a mounting bracket in the prior art, and the water pumping component 120 can be installed at the housing 111 by using the mounting bracket.

[0061] Working principle: In actual operation, the offshore wind power energy storage device utilizes sea wind to drive the second rotating shaft 210 via the wind speed cup 410. This causes the water pumping component 120 to draw seawater and supply it to the heat dissipation chamber 201. The seawater then flows downwards within the heat dissipation chamber 201, washing the heat-conducting fins 202, thus enabling the heat dissipation component 110 to dissipate heat from the housing 100. The downward flow of seawater within the heat dissipation chamber 201 drives the first rotating shaft 340 to rotate, which in turn drives the rotating rod 330 to operate the fan 331, accelerating the airflow within the housing 100 and promoting heat dissipation. Simultaneously, it drives the third rotating shaft 521 to rotate, which in turn drives the cam 710 to rotate, enabling the heat exchange component 130 to discharge water intermittently. This allows the seawater flowing out to exchange heat with the seawater washing onto the guide plate 320, thus ensuring the uniformity of heat dissipation from the heat dissipation component 110 and improving its heat dissipation effect.

[0062] In summary, the above description is only a preferred embodiment of the present invention. All equivalent changes and modifications made within the scope of the claims of the present invention should be covered by the present invention.
