[0033] See also Figure 1 and Figure 2 , Figure 1 A three-dimensional diagram of a vertical axis tidal current energy power generation device provided in some embodiments of the present application, Figure 2 A partial view of a vertical axis tidal current energy power generation device provided in some embodiments of the present application. The embodiments of the present application provide a vertical axis tidal current energy power generation device 100. The vertical axis tidal current energy power generation device 100 comprises a fixed pile 1, a lifting tank 2, a power generation component 3 and a lifting component 4.

[0034] The fixed pile 1 may include a body 11 and a guide rail 12. The body 11 may be disposed on the seabed. Specifically, one end of the body 11 is connected to the seabed, and the other end of the body 11 may extend above the sea surface.

[0035] The guide rail 12 may be disposed on the side of the body 11 and extend along the first direction. Specifically, the guide rail 12 is disposed on the outer side of the body 11, and extends along the first direction. The extension direction of the guide rail 12 may be the same as the extension direction of the body 11, or the extension direction of the guide rail 12 may intersect with the extension direction of the body 11. The guide rail 12 may extend to an end of the body 11 away from the seabed.

[0036] It should be noted that there may be a plurality of guide rails 12, and the plurality of guide rails 12 may be arranged at intervals on the body 11. For example, there may be two guide rails 12, and the two guide rails 12 may be symmetrically arranged on both sides of the body 11.

[0037] One end of the lifting assembly 4 is connected to the lifting tank 2, and the other end is connected to the body 11, which is used to drive the lifting tank 2 to move. Thus, the lifting tank 2 can be driven to move along the guide rail 12 by the lifting assembly 4, so that the position of the lifting tank 2 can be adjusted according to the change of the tide.

[0038] The lifting tank 2 can be sleeved on the body 11. The inner wall of the lifting tank 2 can be provided with a guide groove 21. The guide groove 21 cooperates with the guide rail 12. Therefore, through the cooperation of the guide groove 21 and the guide rail 12, the lifting tank 2 can move along the extension direction of the guide rail 12. At the same time, the way in which the guide rail 12 cooperates with the guide groove 21 is simple in structure and easy to assemble, which is conducive to reducing the cost of the vertical axis tidal energy power generation device 100.

[0039] The power generation assembly 3 may include a support member 31 and a power generation member 32. The support member 31 may be sleeved on the body 11 and connected to the lifting tank 2. The power generation member 32 may be arranged on the support member 31. The power generation member 32 may generate electricity using tidal energy. Thus, when the lifting assembly 4 drives the lifting tank 2 to move, the lifting tank 2 may drive the support member 31 to move, thereby driving the power generation member 32 connected to the support member 31 to move, so that the vertical axis tidal energy power generation device 100 may adjust the position of the power generation member 32 according to the change of the water level.

[0040] According to the vertical axis tidal current energy power generation device 100 of the embodiment of the present application, by setting the guide rail 12 on the body 11, and setting the guide groove 21 matched with the guide rail 12 on the lifting tank 2, when the lifting assembly 4 drives the lifting tank 2 to move, it can drive the power generation assembly 3 connected to the lifting tank 2 to move, so that the platform installation of the vertical axis tidal current energy power generation device 100 can be realized, which has a high degree of integration and is conducive to improving the power generation efficiency. And the vertical axis tidal current energy power generation device 100 can adjust the position of the power generation component 32 according to the change of the water level elevation, so that it can make full use of the kinetic energy of the high velocity layer water flow to generate electricity, thereby improving the energy conversion efficiency of the vertical axis tidal current energy power generation device 100. At the same time, when the vertical axis tidal current energy power generation device 100 needs to be repaired, the lifting tank 2 can be moved away from the seabed through the lifting assembly 4, so that the power generation assembly 3 can be exposed to the water surface, so as to facilitate the inspection and maintenance of the operation personnel, and reduce the operation risk and maintenance difficulty. In addition, the vertical axis tidal energy power generation device 100 of the present application has a simple structure, low cost, low requirements on terrain, and relatively low requirements on water depth.

[0041] Please continue reading Figure 1 and Figure 2In some embodiments, the vertical axis tidal energy power generation device 100 may further include a first support arm 22 and a second support arm 23. The support member 31 may include a first support ring beam 311 and a second support ring beam 312 spaced apart along the extension direction of the body 11. The first support ring beam 311 and the second support ring beam 312 are both sleeved on the body 11. Specifically, in the extension direction of the body 11, the first support ring beam 311 and the second support ring beam 312 may be arranged in parallel, and the second support ring beam 312 may be located on a side of the first support ring beam 311 away from the seabed. The size and shape of the first support ring beam 311 and the second support ring beam 312 may be the same, and such an arrangement may reduce manufacturing costs.

[0042] The power generation element 32 can be arranged between the first support ring beam 311 and the second support ring beam 312. One end of the first support arm 22 is connected to the lifting tank 2, and the other end is connected to the first support ring beam 311. One end of the second support arm 23 is connected to the lifting tank 2, and the other end is connected to the second support ring beam 312. Specifically, one end of the first support arm 22 is connected to the side wall of the lifting tank 2, and the other end is connected to the surface of the first support ring beam 311 facing the second support ring beam 312. One end of the second support arm 23 is connected to the side wall of the lifting tank 2, and the other end is connected to the surface of the second support ring beam 312 facing the first support ring beam 311. Therefore, the connection strength between the first support ring beam 311 and the second support ring beam 312 and the lifting tank 2 can be ensured by the first support arm 22 and the second support arm 23, and the structure is simple, which is conducive to reducing the manufacturing cost of the vertical axis tidal energy power generation device 100.

[0043] Please continue reading Figure 1 and Figure 2 In some embodiments, the angle between the first support arm 22 and the first support ring beam 311 is 45°. The angle between the second support arm 23 and the second support ring beam 312 is 45°. Specifically, the angle between the first support arm 22 and the plane where the first support ring beam 311 is located is 45°, and the angle between the second support arm 23 and the plane where the second support ring beam 312 is located is 45°. This arrangement can ensure the connection strength between the first support ring beam 311 and the second support ring beam 312 and the lifting tank 2, and at the same time can reduce the cost of the first support arm 22 and the second support arm 23.

[0044] Please continue reading Figure 1 and Figure 2 In some embodiments, the vertical axis tidal current energy generating device 100 may further include a dynamic seal bearing (not shown). The generating element 32 is connected to the supporting element 31 through the dynamic seal bearing. Thus, the reliability and safety of the operation of the generating element 32 can be ensured.

[0045] Please continue reading Figure 1In some embodiments, the lifting assembly 4 is detachably connected to the lifting tank 2. Therefore, it is convenient to replace and repair the lifting assembly 4 and the lifting tank 2, thereby facilitating the maintenance of the vertical axis tidal current energy generating device 100.

[0046] Please continue reading Figure 1 In some embodiments, a pin seat may be provided at one end of the lifting tank 2 facing the lifting assembly 4. The lifting assembly 4 may include a static ring beam 41, a lifting rod 42, a pin and a control member. The static ring beam 41 is arranged at one end of the main body 11 away from the seabed. A through hole may be provided on the static ring beam 41, and the lifting rod 42 is penetrated by the through hole. The pin is arranged at one end of the lifting rod 42 close to the lifting tank 2, and the pin is connected to the pin seat. The control member is used to control the movement of the lifting rod 42. Thus, a detachable connection between the lifting tank 2 and the lifting rod 42 can be achieved through the cooperation between the pin and the pin seat. In addition, the lifting rod 42 is controlled to move by the control member, so that the lifting rod 42 can drive the lifting tank 2 to move, and the structure is simple, which is conducive to reducing the cost of the vertical axis tidal energy power generation device 100.

[0047] Exemplarily, the number of the static ring beam 41, the lifting rod 42 and the pin shaft can be multiple, and can be matched with multiple guide rails 12. Such an arrangement can ensure the stability and reliability of the movement of the lifting tank 2.

[0048] Please continue reading Figure 1 and Figure 2 In some embodiments, the vertical axis tidal current energy power generation device 100 further includes a sacrificial anode block 5. The sacrificial anode block 5 is disposed on the outer surface of the support member 31. Exemplarily, the sacrificial anode block 5 can be a zinc block. Thus, the corrosion effect of seawater can be reduced, thereby increasing the service life of the vertical axis tidal current energy power generation device 100.

[0049] Please continue reading Figure 1 and Figure 2 In some embodiments, the vertical axis tidal current energy power generation device 100 may further include a marine warning device 6. The marine warning device 6 is disposed at one end of the body 11 away from the seabed. This arrangement can warn passing ships and reduce the risk of collision between the vertical axis tidal current energy power generation device 100 and ships.

[0050] See also Figure 3 , Figure 3A stereoscopic diagram of a vertical axis tidal current energy power generation device provided for other embodiments of the present application. In some embodiments, the vertical axis tidal current energy power generation device 100 may further include a third support arm 24. The support member 31 may further include a third support ring beam 313.

The third support ring beam 313 is connected to the lifting tank 2 through the third support arm 24, and the power generation member 32 is disposed between the second support ring beam 312 and the third support ring beam 313. Thus, the power generation member 32 between the second support ring beam 312 and the third support ring beam 313 can also generate electricity, thereby forming a multi-layer power generation platform, which can further improve the power generation efficiency of the vertical axis tidal current energy power generation device 100. And the utilization rate of the fixed pile 1 can also be improved, thereby reducing the construction cost and the cost per kilowatt-hour.

[0051] See also Figure 4 , Figure 4 A three-dimensional diagram of a vertical axis tidal current energy power generation device provided for other embodiments of the present application. In some embodiments, the vertical axis tidal current energy power generation device 100 includes a plurality of lifting tanks 2 and a plurality of power generation components 3 arranged at intervals, and one lifting tank 2 is connected to one power generation component 3. Thus, a multi-layer power generation platform can be formed, thereby further improving the power generation efficiency of the vertical axis tidal current energy power generation device 100. In addition, the utilization rate of the fixed piles 1 can be improved, thereby reducing the construction cost and the cost per kilowatt-hour.
