Description

Technical Field

[0001] The present application relates to the technical field of hydroelectric power generation, and particularly to a vertical-axis hydroelectric power generation device. Background Art

[0002] Hydroelectric power generation, as a green power generation method, has been widely promoted and used. Among them, for ocean currents, the hydroelectric power generation capacity that can be achieved is greater. Chinese Patent Publication No. CN 206640531U discloses a solar-hydrokinetic energy integrated power generation device, in which a generator is provided on a floating platform. During the use of the floating platform, it is moored by being put into the water through an anchor. However, for deep-sea areas, after the anchor is put into the water, the anchor is prone to deviation during the sinking process due to the impact of water flow. In order to meet the mooring requirements of the floating platform, multiple anchors need to be put in. In this way, the positions of the multiple anchors on the seabed cannot be controlled, and it is easy to have the distance between the anchors too small, so that the tension cable cannot exert a uniform and stable pulling force on the floating platform, resulting in the mooring reliability of the floating platform being affected. In view of this, how to design a technology to improve the accuracy of the mooring position to improve the reliability of the floating platform is the technical problem to be solved by the present application. Utility Model Content

[0009] The present application also provides a hydroelectric power generation device, including:

[0010] A floating platform, the floating platform adopts the above floating platform, a generator and a power input shaft are arranged on the floating platform, and the motor shaft of the generator is in transmission connection with the power input shaft;

[0031] As Figures 1 - 8 shown, an embodiment of the present application provides a vertical-axis hydraulic power generation device, including:

[0032] A power generation module, the power generation module includes a floating platform 11 and a generator 12, the generator 12 is arranged on the floating platform 11, and the motor shaft of the generator 12 is in transmission connection with the power input shaft 13 through a gearbox 14.

[0033] A driving module 2, the driving module 2 includes a rotating main shaft 21 and a plurality of water wheel components. The water wheel components include a mounting base 22 and a plurality of blades 23. The plurality of blades 23 are arranged on the mounting base 22. A shaft hole is provided on the mounting base 22. The plurality of water wheel components are arranged in sequence from top to bottom. The rotating main shaft 21 is arranged vertically and inserted into the shaft hole;

[0034] The upper end of the rotating main shaft 21 is connected to the power input shaft 13.

[0035] Specifically, the floating hydraulic power generation device provided in this application uses a power generation module to generate electricity. The generator 12 on the power generation module is located on the floating platform 11 and is not immersed in water. Therefore, the situation where the generator 12 is damaged due to water ingress caused by seal failure can be effectively reduced, and the reliability of the generator 12 in use is effectively improved, so as to improve the overall reliability of the floating hydraulic power generation device.

[0036] The driving module 2 is connected to the power input shaft 13 through the rotating main shaft 21, and transmits the driving force to the power input shaft 13 through the rotating main shaft 21 through a plurality of water wheel components, so as to drive the generator 12 to generate electricity.

[0037] Embodiment 1, as Figure 7 and Figure 10 shown, in order to accurately moor the floating platform 11, it is necessary to keep the relative inclination positions of multiple anchor chains 33 configured at the bottom of the floating platform 11 unchanged. However, the method of dropping the ship anchor underwater cannot accurately control the positions of each ship anchor on the seabed. To solve this problem, the following structural improvements are made to the seabed anchoring method of the vertical axis hydraulic power generation equipment.

[0038] The bottom of the floating platform 11 is further provided with an anchoring module 3. The anchoring module 3 includes a launching frame 31 and a plurality of counterweight components 32. A plurality of anchor chains 33 are provided on the launching frame 31. The counterweight components 32 are arranged on the launching frame 31;

[0039] The upper end of the anchor chain 33 is connected to the floating platform 11, and the lower end of the anchor chain 33 is connected to the corresponding counterweight component 32. The anchor chain 33 is inclined between the floating platform 11 and the corresponding counterweight component 32, and the anchor chain 33 is inclined downward from top to bottom in the outer direction of the floating platform 11.

[0040] Specifically, during the construction process, the placement frame 31 and the counterweight components 32 are first put into the seabed together. Then, the anchor chain 33 is connected between the floating platform 11 and the placement frame 31. Since the structure of the placement frame 31 itself has precisely defined the positions of different counterweight components 32, in this way, for different anchor chains 33, the bottom connection positions of the anchor chains 33 can be determined and remain unchanged. Furthermore, it ensures that the floating platform 11 at the top connected by the anchor chain 33 can obtain reliable pulling and positioning by the anchor chain 33. In this way, the relative positions between the anchor chains 33 can be precisely controlled, solving the problem that the positions of the bottom ship anchors on the seabed cannot be controlled in the way of separately placing ship anchors, and improving the placement position accuracy of the mooring module 3.

[0041] By arranging a placement frame 31 on the mooring module 3 to install and position multiple counterweight components 32 through the placement frame 31, the relative positions of the multiple counterweight components 32 are positioned by the placement frame 31. In this way, after the mooring module 3 is put into the sea and sinks to the seabed, the relative positions of the multiple counterweight components 32 will not change. In this way, the relative positions of the multiple anchor chains 33 connected between the counterweight components 32 and the floating platform 11 can be kept in a stable state. During use, multiple anchor chains 33 can provide pulling forces in multiple directions to the floating platform 11 floating above. Since the positions of the anchor chains 33 are precisely positioned by the placement frame 31, furthermore, each anchor chain 33 can play a good role in positioning the floating platform 11 at the top, enabling the floating platform 11 to float smoothly on the sea surface to ensure that the floating platform 11 can maintain a stable floating state on the water surface, thereby improving the use reliability of the floating platform 11.

[0042] Furthermore, the placement frame 31 includes multiple telescopic beams 311. Locking members 312 are arranged on the telescopic beams 311, and the locking members 312 are configured to lock the telescopic beams 311 after the telescopic beams 311 are extended or retracted in place; wherein, the multiple telescopic beams 311 are connected end to end in sequence.

[0043] Specifically, in order to further improve the use versatility of the mooring module 3 to meet the placement requirements of waters with different depths, for the placement frame 31, it is a telescopic frame itself to realize the expansion and contraction of its own size. Specifically, during use, the multiple telescopic beams 311 of the placement frame 31 can adjust the lengths of the telescopic beams 311 according to the depth of the water area where they are located to realize the adjustment of the relative positions of the counterweight components 32, and further ensure the inclination angles of the anchor chains 33 to meet the requirements for the stable floating of the floating platform 11 at the top.

[0044] Further, the telescopic beam 311 includes an outer sleeve 3111 and an inner core tube 3112. The outer sleeve 3111 is sleeved outside the inner core tube 3112. The outer sleeve 3111 and the inner core tube 3112 can slide relative to each other. The locking member 312 is disposed on the outer sleeve 3111 and is configured to lock the position of the inner core tube 3112 relative to the outer sleeve 3111.

[0045] Specifically, for the telescopic beam 311, in order to meet the telescopic requirements, the outer sleeve 3111 is used in cooperation with the inner core tube 3112. The outer sleeve 3111 can move relative to the inner core tube 3112 to adjust the length of the telescopic beam 311.

[0046] Meanwhile, after the length of the telescopic beam 311 is adjusted, the relative position between the outer sleeve 3111 and the inner core tube 3112 is further locked by the locking member 312. In this way, during the delivery process when the delivery frame 31 is adjusted to the appropriate size, since the locking member 312 locks the outer sleeve 3111 and the inner core tube 3112 and they will not move relative to each other, the size of the delivery frame 31 will not be deformed during the delivery process, thereby improving the reliability and convenience of use.

[0047] Furthermore, a plurality of threaded holes (not shown) are provided on the outer sleeve 3111, and a plurality of positioning holes (not shown) are provided on the inner core tube 3112. The plurality of threaded holes extend along the length direction of the outer sleeve 3111, and the plurality of positioning holes extend along the length direction of the inner core tube 3112. The locking member 312 is a locking bolt, and the locking bolt is threadedly connected to the corresponding threaded hole and inserted into the corresponding positioning hole.

[0048] Specifically, the locking member 312 can be used in the form of a locking bolt to lock the position between the outer sleeve 3111 and the inner core tube 3112. That is, after the relative position between the outer sleeve 3111 and the inner core tube 3112 is adjusted, the threaded hole will be aligned with the corresponding positioning hole. Then, the locking bolt is tightened so that the locking bolt is inserted into the corresponding positioning hole. In this way, the position between the outer sleeve 3111 and the inner core tube 3112 can be locked.

[0049] Even further, for two adjacent telescopic beams 311, the outer sleeve 3111 of one telescopic beam 311 is connected to the inner core tube 3112 of the other telescopic beam 311 to form a fixed connection part.

[0050] Specifically, the delivery frame 31 formed by connecting the telescopic beams 311 can be an equilateral triangle or a rectangle. In this way, the ends of two adjacent telescopic beams 311 can be fixedly connected together by welding.

[0051] After the ends of the two telescopic beams 311 are welded together, a fixed connection part is formed, and the counterweight member 32 can be connected to the corresponding fixed connection part. For example: the counterweight member 32 can be connected to the counterweight member 32 by a chain, or the counterweight member 32 can be welded to the fixed connection part by a connecting beam.

[0052] Furthermore, the counterweight member 32 is a stone-throwing basket, and the stone-throwing basket is configured to hold counterweight stones.

[0053] Specifically, in the case of the counterweight member 32 adopting the form of a stone-throwing basket, after the mooring module 3 is transported to the designated water area, a certain amount of stones are placed in the stone-throwing basket, and then the mooring module 3 is put into the water. The stone-throwing basket is arranged below the placement frame 31. For example: the stone-throwing basket is suspended on the fixed connection part by a chain; or the stone-throwing basket can be directly welded to the fixed connection part.

[0054] Based on the above technical solution, optionally, the floating platform 11 includes a floating frame 111 and floating members 112. The first mounting opening 110 is provided on the floating frame 111, and the floating members 112 are arranged on the floating frame 111.

[0055] Specifically, for the floating platform 11, it needs to meet the installation requirements of the generator 12 at the top and the bottom drive module 2. Therefore, for the floating platform 11, it adopts a frame structure. That is, floating members 112 are arranged on the floating frame 111 to form the floating platform 11. The floating frame 111 serves as the installation main body, and the frame structure can improve the structural strength of the floating platform 11 itself; while the floating members 112 can adopt floating objects in the prior art, such as floating boxes, floating blocks and other physical entities, and the floating force required by the floating platform 11 can be increased through the floating members 112.

[0056] Furthermore, the floating frame 111 is a hollow structure, and the floating members 112 are arranged in the hollow structure.

[0057] Specifically, in order to facilitate the installation and placement of the floating members 112, the floating frame 111 is set as a hollow structure. In this way, the floating members 112 can be built into the hollow structure of the floating frame 111. On the one hand, various positions of the floating frame 111 can be fully utilized to arrange the floating members 112 to improve the overall floating force of the floating platform 11. On the other hand, when the floating members 112 at specific positions are damaged, the floating members 112 in the corresponding hollow structure can be replaced separately to improve the maintenance convenience.

[0058] Among them, in order to improve the flatness of the upper surface of the floating platform 11, a platform plate (not shown) may also be provided on the upper surface of the floating frame 111, and the platform plate covers the hollow structure.

[0059] Specifically, the platform plate is laid on the upper surface of the floating frame 111 to cover the hollow structure, so that the upper surface of the floating platform 11 is more flat, and thus it is convenient for the operator to perform daily maintenance operations on the surface of the floating platform 11.

[0060] Among them, the platform plate can be an integral plate (such as multiple iron plates welded together and fixed on the floating frame 111). Or, the platform plate can be composed of multiple split iron plates, and each iron plate covers the corresponding hollow structure; and, the iron plates can be connected to the floating frame 111 in a hinged manner, so that when repairing the floating component 112 at the corresponding position, the iron plate at the corresponding position can be opened to facilitate the operator to repair and replace the floating component 112 on the floating platform 11.

[0061] Furthermore, a plurality of cable bollards 113 are provided on the floating frame 111, and the cable bollards 113 are arranged close to the edge of the floating frame 111.

[0062] Specifically, the cable bollards 113 can fix the cables on the repair ship through the cable bollards 113 after the repair ship approaches the floating platform 11.

[0063] Still further, a plurality of cranes 114 are provided on the floating frame 111, and the cranes 114 are arranged close to the edge of the floating frame 111.

[0064] Specifically, in order to facilitate the installation and repair of the underwater drive module 2 on the floating platform 11, a crane 114 may also be provided on the floating frame 111. The crane 114 can hoist the corresponding components into the water during the installation and repair process, and can also hoist the components that need to be replaced underwater out of the water surface.

[0065] Embodiment 2, in order to improve the use reliability of the vertical axis hydraulic power generation device and improve the power generation efficiency, the following structural improvement design is carried out in this application.

[0066] The power generation module provided by this application further includes a self-balancing component 16; the self-balancing component includes a first frame 161 and a second frame 162. A first rotating shaft is provided on the first frame 161, and a second rotating shaft is provided on the second frame 162. The axis of the first rotating shaft is perpendicular to the axis of the second rotating shaft. The second rotating shaft is rotatably provided on the first frame 161; a first mounting port 110 is provided on the floating platform 11, the first frame 161 is located in the first mounting port 110, the first rotating shaft is rotatably provided on the floating platform 11, a power input shaft 13 is provided on the second frame 162, and the generator 12 is fixed on the second frame 162.

[0067] Specifically, the self-balancing component is configured with a first frame 161 and a second frame 162 that can rotate relative to each other, and the axis of the first rotating shaft on the first frame 161 and the axis of the second rotating shaft on the second frame 162 are perpendicular to each other. After the first frame 161 is installed on the floating platform 11 through the first rotating shaft, the first frame 161 can rotate in the first mounting port 110 around the axis of the first rotating shaft.

[0068] The generator 12 is installed on the second frame 162 and connected to the power input shaft 13 on the second frame 162. The driving module 2 is connected to the lower end of the power input shaft 13 through the rotating main shaft 21. During the normal power generation process, the floating platform 11 floating on the water surface will fluctuate due to the water surface fluctuations. During the shaking process of the floating platform 11, the first frame 161 and the second frame 162 will also rotate accordingly, so that the power input shaft 13 is in a substantially vertical state under the gravity of the driving module 2 at the bottom, so as to effectively utilize the water flow for power generation to improve the power generation efficiency; at the same time, the deflection force generated by the rotating main shaft 21 on the power input shaft 13 is small, and the generator 12 is fixed on the second frame 162 to always maintain a reliable connection with the power input shaft 13, thereby improving the reliability of use of the generator 12.

[0069] It should be noted that the "substantially vertical" mentioned in this application refers to the state in which the rotating main shaft 21 is vertically arranged during the rotation power generation process. As is known to those skilled in the art, under the action of the water flow, the driving module 2 will inevitably cause the rotating main shaft 21 to tilt at a certain angle under the action of the water flow. And the above "substantially vertical" means that the included angle between the axis of the rotating main shaft 21 and the direction of its own gravity can be considered to be in a substantially vertical state within a set range. The set range of the above included angle is to satisfy that the driving module 2 can drive the rotating main shaft 21 to generate power normally and efficiently under the action of the water flow. For example: the included angle can be 0-30 degrees. The specific range of the included angle is not limited here.

[0070] In one embodiment, the first frame 161 and the second frame 162 are arranged horizontally, and the first frame 161 surrounds the periphery of the second frame 162.

[0071] Specifically, the first frame 161 and the second frame 162 are arranged horizontally to make full use of the space of the first mounting opening 110 to mount the self-balancing assembly 16. The first rotating shaft is mounted on the first bearing 115 provided on the floating platform 11. Correspondingly, the second rotating shaft is mounted on the second bearing on the first frame 161.

[0072] In one embodiment, a second mounting opening 163 is provided on the second frame 162. A stepped mounting surface 164 is provided in the second mounting opening 163. A bottom ring 165 is provided on the stepped mounting surface 164. A first circular chute (not marked) is provided on the upper surface of the bottom ring 165; an axle ring 131 is provided on the power input shaft 13. A second circular chute is provided on the lower surface of the axle ring 131; the self-balancing assembly 16 further includes a ring frame 166 and a plurality of support balls 167. A number of limiting through holes (not shown) are provided on the ring frame 166. The support balls 167 are located in the limiting through holes; the ring frame 166 is located between the bottom ring 165 and the axle ring 131, and the support balls 167 are located between the first circular chute and the second circular chute.

[0073] Specifically, in order to improve the mounting reliability of the power input shaft 13, an axle ring 131 is further provided on the power input shaft 13. In order to ensure that the power input shaft 13 can rotate smoothly on the second frame 162, a stepped surface 1513 is further provided on the second frame 162 to mount the bottom ring 165. The axle ring 131 is arranged above the bottom ring 165 and a support ball 167 is provided between the two to meet the requirement of supporting the rotation of the axle ring 131.

[0074] During actual use, the power input shaft 13 can define its own mounting position in the second mounting opening 163 through the axle ring 131, and the support ball 167 below the axle ring 131 is used to ensure smooth rotation driven by the waterway module.

[0075] In Embodiment 3, in order to enable the rotating main shaft 21 to rotate in a substantially vertical state during use, and to enable it to quickly automatically reset after the rotating main shaft 21 tilts due to excessive water flow impact, the following improvements are made to the vertical-axis hydroelectric power generation device.

[0076] A counterweight assembly 25 is provided at the lower end of the rotating main shaft 21. The counterweight assembly 25 is configured to apply a downward pulling force to the lower end of the rotating main shaft 21.

[0077] Specifically, the counterweight assembly 25 is arranged at the lower end of the rotating main shaft 21. The counterweight assembly 25 uses its own gravity to keep the rotating main shaft 21 stable, so that the rotating main shaft 21 can be in a substantially vertical state below the water surface or the inclination angle is within a set range (for the set range of the inclination angle, it is necessary to configure the counterweight assembly 25 with corresponding weights according to the water flow velocity below the water surface, which is not limited here).

[0078] In one embodiment, the counterweight assembly 25 includes a connecting rod 251 and a plurality of counterweight blocks 253. A supporting portion 252 is provided at the lower end of the connecting rod 251. The size of the supporting portion 252 is larger than that of the connecting rod 251. A through hole is provided on the counterweight block 253. The connecting rod 251 passes through the through hole. A plurality of the counterweight blocks 253 are stacked on the supporting portion 252. The upper end of the connecting rod 251 is connected to the lower end of the rotating main shaft 21.

[0079] Specifically, in order to facilitate the assembly and installation of the counterweight assembly 25, a plurality of counterweight blocks 253 are used to meet the weight requirements of the configuration assembly. According to the usage requirements, the corresponding number of counterweight blocks 253 can be configured and connected to the bottom of the rotating main shaft 21 through the connecting rod 251.

[0080] Further, the counterweight block 253 has a disc-shaped structure, and a water flow interval is formed between two adjacent counterweight blocks 253.

[0081] Specifically, for the counterweight block 253, in order to reduce the water resistance generated by the counterweight block 253, the counterweight block 253 adopts a disc structure. In this way, the arc surface formed by the outer peripheral circle of the counterweight block 253 is used to reduce the resistance of the water flow.

[0082] At the same time, a water flow interval is further formed between two adjacent counterweight blocks 253. During use, water flow will pass through the water flow interval, and the water flow flowing in the water flow interval can cooperate with the rotating counterweight block 253 to further stabilize the attitude of the rotating main shaft 21, so that the rotating shaft can maintain a normal power generation state and generate electricity efficiently under the drive of the water flow.

[0083] Still further, in order to form a water flow interval between two counterweight blocks 253, a spacer ring can be placed between two adjacent counterweight blocks 253, and the spacer ring can separate the two counterweight blocks 253. Or, an annular boss (not shown) is provided on the counterweight block 253 around the through hole; for two adjacent counterweight blocks 253, the upper counterweight block 253 abuts against the annular boss of the lower counterweight block 253.

[0084] Specifically, by configuring an annular boss on the counterweight 253 itself, after sleeving a plurality of counterweights 253 on the connecting rod 251, two adjacent counterweights 253 are spaced apart by the annular boss. In this way, after sleeving the counterweights 253 on the connecting rod 251, a water flow interval can be formed between the two counterweights 253 through the annular boss, which is convenient for assembly.

[0085] Furthermore, the upper end of the connecting rod 251 is fixedly connected to the lower end of the rotating main shaft 21. Specifically, the connecting rod 251 can be connected to the bottom of the rotating main shaft 21 through connecting devices such as couplings to facilitate rapid on-site assembly.

[0086] Alternatively, the upper end of the connecting rod 251 is connected to the lower end of the rotating main shaft 21 through a universal joint. Specifically, in order to avoid the connecting rod 251 generating excessive torque on the rotating main shaft 21, the connecting rod 251 can also be connected to the lower end of the rotating main shaft 21 through a universal joint. In this way, the connecting rod 251 can deflect a certain amount relative to the rotating bearing.

[0087] In Embodiment 4, in order to improve the waterproof protection ability of the generator 12, the external waterproof structure of the generator 12 is improved.

[0088] A waterproof cover group 15 is further provided on the floating platform 11. The waterproof cover group 15 includes an upper cover body 151 and a lower surrounding plate 152. The lower surrounding plate 152 is of an annular structure and is provided on the floating platform 11. The lower surrounding plate 152 surrounds the periphery of the generator 12. The upper cover body 151 is provided on the lower surrounding plate 152 and covers the upper part of the generator 12. The lower edge of the upper cover body 151 forms an extension part 1511, and the extension part 1511 extends downward and shields the outside of the connection part formed between the upper cover body 151 and the lower surrounding plate 152.

[0089] Specifically, a waterproof cover group 15 is further provided on the second frame 162 to shield and protect the generator 12 on the second frame 162 through the waterproof cover group 15. Among them, the lower surrounding plate 152 is fixedly installed on the second frame 162 around the generator 12 and the power input shaft 13, and the upper cover body 151 is installed above the lower surrounding plate 152 to cover the generator 12.

[0090] At the same time, since the lower edge of the upper cover body 151 is also provided with an extension part 1511, the extension part 1511 can effectively shield the connection part between the upper cover body 151 and the lower surrounding plate 152. During use, even if the sea waves hit the waterproof cover group 15, the extension part 1511 can effectively block the seawater from entering the waterproof cover group 15 through the connection part between the upper cover body 151 and the lower surrounding plate 152.

[0091] In this way, the generator 12 is covered by the waterproof cover group 15 to block the sea waves during use through the waterproof cover group 15, so as to play a good role in waterproofing the generator 12.

[0092] Furthermore, a stepped surface 1513 is formed between the extension part 1511 and the inner wall of the upper cover body 151, and the stepped surface 1513 abuts against the upper edge of the lower apron 152.

[0093] Specifically, during the installation process, after the generator 12 is placed in the area surrounded by the lower apron 152, the upper cover body 151 can be installed on the lower apron 152. During the installation of the upper cover body 151, the upper cover body 151 is hoisted above the upper apron and is lapped on the upper edge of the upper apron through the stepped surface 1513, so that the upper cover can be installed on the upper apron.

[0094] Among them, in order to improve the connection reliability between the upper cover body 151 and the lower apron 152, after the upper cover body 151 and the lower apron 152 are lapped together through the stepped surface 1513, the upper cover body 151 and the lower apron 152 need to be further connected and fixed. For this purpose, a first connecting part 1512 is provided on the upper cover body 151, a second connecting part 1521 is provided on the lower apron 152, and the first connecting part 1512 is connected to the second connecting part 1521.

[0095] Specifically, after the upper cover body 151 is hoisted onto the lower apron 152, the first connecting part 1512 and the second connecting part 1521 are connected and matched, so that the upper cover body 151 and the lower apron 152 are firmly connected together to improve the connection reliability during use.

[0096] The physical entities of the first connecting part 1512 and the second connecting part 1521 can adopt various structural forms. For example: the first connecting part 1512 is a plurality of connecting columns provided at the lower edge of the upper cover body 151, the lower end of the connecting column is provided with a head, and the outer peripheral dimension of the head is larger than the outer peripheral dimension of the connecting column; the second connecting part 1521 is a strip-shaped hole formed on the lower apron 152, and the opening dimension of the strip-shaped hole becomes smaller along the length direction; the connecting column is inserted into the strip-shaped hole, and the head is arranged below the strip-shaped hole and is configured to limit the connecting column from disengaging from the strip-shaped hole.

[0097] Specifically, connecting columns are provided at the lower part of the upper cover body 151. Correspondingly, strip-shaped holes are provided at the upper part of the lower surrounding plate 152. During the assembly process, after hoisting the upper cover body 151 above the lower surrounding plate 152, the connecting columns are aligned with the corresponding strip-shaped holes. Then, after the connecting columns are inserted into the strip-shaped holes, the upper cover body 151 is rotated by a certain angle so that the ends of the connecting columns move to the ends with smaller dimensions of the strip-shaped holes to prevent the connecting columns from disengaging from the strip-shaped holes. In this way, the upper cover body 151 can be installed on the lower surrounding plate 152.

[0098] Alternatively, the first connecting portion 1512 is a support beam provided on the upper cover body 151. The support beam has an arc-shaped structure, and insertion interfaces are formed at both ends of the support beam. The second connecting portion 1521 is a plugging protrusion provided on the lower surrounding plate 152, and the plugging protrusion is plugged into the corresponding insertion interface.

[0099] Specifically, during the assembly process, after hoisting the upper cover body 151 above the lower surrounding plate 152, the plugging protrusion is aligned with the insertion interface. Then, the step surface 1513 of the upper cover body 151 abuts against the lower surrounding plate 152 so that the plugging protrusion is inserted into the insertion interface to install the upper cover body 151 on the lower surrounding plate 152. Preferably, the plugging protrusion and the support beam can be further connected by bolts to improve the connection reliability between the upper cover body 151 and the lower surrounding plate 152.

[0100] Among them, for the waterproof cover group 15, in order to reduce wind resistance and improve structural strength, the upper cover body 151 has a hemispherical structure, and for the lower surrounding plate 152, it can have a cylindrical structure or a hemispherical structure.

[0101] In addition, an indicator light 17 is also provided on the upper cover body 151. The indicator light 17 can play an indicating role at night when the vertical-axis hydroelectric power equipment floats in the sea, so as to improve the use safety.

[0102] In Embodiment 5, in order to improve the power generation efficiency of the blades 23 and improve the use reliability, a plurality of the blades 23 are vertically arranged and rotatably provided on the mounting seat 22.

[0103] Since the blades 23 are frequently subjected to the reciprocating force of the water flow, the blades 23 are easily damaged only relying on the support at the hinge parts. For this reason, a plurality of limit stoppers 24 are further provided on the mounting seat 22, and the limit stoppers 24 are arranged between two adjacent blades 23.

[0104] Specifically, during the use process, the water flow is used to drive the blades 23 to drive the rotating main shaft 21 to rotate. And, during the rotation of the blades 23 following the rotating main shaft 21, the driving forces of the water flow on the blades 23 at different positions are different.

[0105] When the blade 23 is driven by water flow to drive the rotation of the rotating main shaft 21, the limiting stop 24 can support the blade 23. Thus, when the blade 23 is under force, the blade 23 is assisted by the limiting stop 24 to support, which can reduce the force on the hinged part of the blade 23 and improve the reliability of use.

[0106] When the blade 23 is driven by water flow to block the normal rotation of the rotating main shaft 21, the limiting stop 24 can also support the blade 23, further improving the reliability of use of the blade 23.

[0107] By providing the limiting stop 24 on the mounting base 22, the blade 23 is located between the two limiting stops 24 and can rotate on the mounting base 22. In this way, during actual use, since the blades 23 are distributed around the rotating main shaft 21, the blades 23 at different positions are subjected to different forces during the water flow. For the blade 23 where the water flow flows towards the blade 23 to generate a driving force on the rotating main shaft 21, the blade 23 will abut against the corresponding limiting stop 24 to utilize the limiting stop to support the blade 23; in addition, for the blade 23 where the water flow flows towards the blade 23 to generate a driving force on the rotating main shaft 21, the blade 23 can also be supported by the corresponding side, so that during the rotation of the blade 23, the limiting stop 24 can additionally provide a supporting force, and the force on the hinged part of the blade 23 can also be reduced. Furthermore, the frequent repeated force on the hinged part of the blade 23 can be reduced and damaged, improving the reliability of use of the blade 23 and the overall reliability of use of the suspended hydraulic power generation device.

[0108] Among them, a space for restricting the rotation angle of the blade 23 will be formed between two adjacent limiting stops 24.

[0109] In an embodiment, a driving surface 231 is formed on one side wall of the blade 23, and a first guiding surface 232 is formed on the other side wall of the blade 23. The driving surface 231 is an arc-shaped concave surface, and the first guiding surface 232 is an arc-shaped convex surface.

[0110] Specifically, the blade 23 is designed such that one side wall forms a driving surface 231 with an arc-shaped concave surface, and the other side wall forms a first guiding surface 232 with an arc-shaped convex surface. When the water flow passes through the driving surface 231, due to the pressure difference generated by the concave surface design, the blade 23 can capture the water flow energy more efficiently and drive the rotation of the rotating main shaft 21. At the same time, the convex surface design of the first guiding surface 232 helps to reduce the resistance of the water flow, enabling the water flow to flow through the blade 23 more smoothly and improving the energy conversion efficiency of the entire device.

[0111] Through the concave-convex surface design of the blade 23, the water flow energy can be utilized more effectively, improving the power generation efficiency. In addition, this design can also reduce the water flow resistance on the surface of the blade 23, enabling the blade 23 to rotate more smoothly and extending the service life of the device. At the same time, the concave-convex surface design can be optimized according to different water flow conditions, with stronger adaptability.

[0112] In another embodiment, one end of the limiting stop member 24 is fixedly installed on the rotating main shaft 21, and the other end of the limiting stop member 24 is arranged in a suspended manner.

[0113] Specifically, one end of the limiting stop member 24 is fixed to the rotating main shaft 21, and the other end is arranged in a suspended manner. The purpose of this design is to limit the maximum rotation angle of the blade 23 through the flexibility of the suspended end without affecting the normal rotation of the blade 23, ensuring that the blade 23 will not rotate excessively under high water flow speeds, thereby protecting the rotating main shaft 21 and the blade 23. The limiting stop member 24 can effectively protect the blade 23 and the rotating main shaft 21, avoiding mechanical damage caused by excessive rotation of the blade 23.

[0114] Furthermore, a support surface 241 is formed on one side wall of the limiting stop member 24, and the outer contour of the support surface 241 matches the first guiding surface 232 of the blade 23; another side plate of the limiting stop member 24 forms a second guiding surface 242, and the second guiding surface 242 is an arc-shaped convex surface.

[0115] Specifically, the limiting stop member 24 is designed such that one side wall forms a support surface 241 that matches the guiding surface of the blade 23, and the other side wall forms a second guiding surface 242 that is an arc-shaped convex surface. The support surface 241 matches the first guiding surface 232 of the blade 23. When the blade 23 is driven by the water flow to drive the rotating main shaft 21 to rotate, the first guiding surface 232 of the blade 23 can make good contact with the support surface 241 of the limiting stop member 24, providing stable support through the support surface 241 to prevent the blade 23 from shifting or deforming during rotation. The design of the second guiding surface 242 helps to further optimize the water flow path, reduce the water flow resistance, and improve the overall efficiency of the device.

[0116] Through the design of the limiting stop member 24, the stability and durability of the blade 23 can be improved, and the service life of the device can be extended. At the same time, the design of the second guiding surface 242 can further reduce the water flow resistance and improve the energy conversion efficiency.

[0117] Further, in order to facilitate the subsequent separate maintenance of each water turbine assembly, the rotating main shaft 21 includes a plurality of rotating sub-shafts 211. The plurality of rotating sub-shafts 211 are coaxially arranged, and two adjacent rotating sub-shafts 211 are detachably connected together. The rotating sub-shaft 211 located at the topmost part is detachably connected to the power input shaft 13;

[0118] Each rotating sub-shaft 211 is provided with the water turbine assembly.

[0119] Specifically, an independent water turbine assembly is correspondingly arranged on each rotating sub-shaft 211. During use, when a certain water turbine assembly is damaged and needs to be replaced and repaired, the rotating sub-shaft 211 corresponding to the damaged water turbine assembly can be separately disassembled, and then the damaged water turbine assembly can be separately replaced to improve the convenience of maintenance.

[0120] Embodiment Six, in another embodiment of the present application, a maintenance method for a vertical-axis hydraulic power generation device is further provided, including:

[0121] During the process of replacing the water turbine assembly at the topmost part, first, suspend and connect the mounting base 22 of the water turbine assembly below the water turbine assembly to be disassembled with the floating platform 11 above. Then, disconnect the rotating sub-shaft 211 of the water turbine assembly to be disassembled from the power input shaft 13 and the rotating sub-shaft 211 of the water turbine assembly below to disassemble and take out the water turbine assembly to be disassembled; again, place the new water turbine assembly between the floating platform 11 and the water turbine assembly below, and connect the rotating sub-shaft 211 on the new water turbine assembly between the power input shaft 13 and the rotating sub-shaft 211 of the water turbine assembly below.

[0122] Specifically, when the drive module 2 at the topmost part needs to be disassembled and replaced, it is necessary to suspend and connect the mounting base 22 of the drive module 2 below the drive module 2 to be disassembled with the floating platform 11 above through a suspension device (such as a steel chain or a steel wire rope). The suspension device should have sufficient load-bearing capacity and stability to ensure that there will be no structural deformation or instability during the suspension process. Through the connection of the suspension device, the stability of the drive module 2 below and the entire floating platform 11 can be ensured when disassembling the drive module 2 at the topmost part, preventing structural instability problems caused by disassembly.

[0123] Gradually disconnect the connection between the rotating sub-shaft 211 of the drive module 2 to be disassembled and the power input shaft 13 and the rotating sub-shaft 211 of the drive module 2 below, and then the damaged drive module 2 can be taken out. Then, place the new drive module 2 between the floating platform 11 and the drive module 2 below, and ensure that its rotating sub-shaft 211 is correctly docked with the power input shaft 13 and the rotating sub-shaft 211 of the drive module 2 below.

[0124] After the replacement is completed, disassemble the suspension device.

[0125] During the process of replacing the middle drive module 2, first suspend and connect the mounting base 22 of the drive module 2 below the drive module 2 to be disassembled with the mounting base 22 of the drive module 2 above. Then, disconnect the rotating sub-axis 211 of the drive module 2 to be disassembled from the rotating sub-axes 211 of the upper and lower drive modules 2 to remove the drive module 2 to be disassembled. Place the new drive module 2 between the upper and lower drive modules 2 again, and connect the rotating sub-axis 211 of the new drive module 2 between the rotating sub-axes 211 of the upper and lower drive modules 2.

[0126] Specifically, during the process of replacing the middle drive module 2, use the suspension device to suspend and connect the mounting base 22 of the drive module 2 below the drive module 2 to be disassembled with the mounting base 22 of the drive module 2 above. This step ensures the stability of the upper and lower parts of the structure after disassembling the middle drive module 2 and prevents structural instability caused by disassembly. Then, gradually disconnect the connection between the rotating sub-axis 211 of the drive module 2 to be disassembled and the rotating sub-axes 211 of the upper and lower drive modules 2, and then move the drive module 22 to be disassembled out from between the upper and lower drive modules 2. The operation should be carried out slowly to ensure smooth movement.

[0127] After removing the middle drive module 2, the suspension device connects the two spaced drive modules 2 together to prevent the lower drive module 2 from sinking underwater. Finally, place the new drive module 2 between the upper and lower drive modules 2 and ensure that its rotating sub-axis 211 is correctly docked between the rotating sub-axes 211 of the upper and lower drive modules 2.

[0128] After the replacement is completed, disassemble the suspension device.

[0129] During the process of replacing the bottom drive module 2, disconnect the rotating sub-axis 211 of the drive module 2 to be disassembled from the rotating sub-axis 211 of the drive module 2 above to remove the drive module 2 to be disassembled. Place the new drive module 2 below the drive module 2 above again, and connect the rotating sub-axis 211 of the new drive module 2 to the rotating sub-axis 211 of the drive module 2 above.

[0130] Specifically, during the process of replacing the drive module 2 at the bottom, a suspension device is used to suspend and connect the counterweight assembly 25 to the mounting seat 22 of the drive module 2 below the drive module 2 to be disassembled. Then, the connection between the rotating sub-shaft 211 of the drive module 2 to be disassembled and the rotating sub-shaft 211 of the upper drive module 2 is gradually disconnected to ensure the safety of each operation. After removing the drive module 2 to be disassembled, a new drive module 2 is placed below the upper drive module 2, and it is ensured that its rotating sub-shaft 211 is correctly docked with the rotating sub-shaft 211 of the upper drive module 2. Finally, the counterweight assembly 25 is reconnected to the rotating sub-shaft 211 of the new drive module 2.

[0131] After the replacement is completed, the suspension device is disassembled.

[0132] The above is only the specific implementation manner of the present application, but the protection scope of the present application is not limited thereto. Any changes or substitutions that can be easily thought of by those skilled in the technical field within the technical scope disclosed in the present application should be covered within the protection scope of the present application. Therefore, the protection scope of the present application shall be subject to the protection scope of the claims.
