Description

Technical Field

[0001] The present invention relates to the technical field of hydraulic power generation, and particularly to a frame-type floating platform and a hydraulic power generation device. Background Art

[0002] Hydraulic power generation, as a green power generation method, has been widely promoted and used. Among them, for ocean currents, the ability to achieve hydraulic power generation is greater. In order to meet the requirements of power generation in the sea, floating platforms are usually used to install generators and impellers. In order to meet the buoyancy requirements, floating platforms usually use floating objects or inflation methods. For example, Chinese Patent Publication No. CN208778137U discloses a hydraulic power generation device that uses a floating platform to carry components such as generators and impellers. During use, the floating platform is inflated or deflated according to the required buoyancy of the floating platform. However, since the floating platform needs to float on the sea surface during use, during long-term use, it is easy for the floating platform to be damaged by external objects. And when using the inflation and deflation method, after the floating platform is damaged by collision, the overall buoyancy of the floating platform is affected and the maintenance difficulty is also relatively large. In view of this, how to design a floating platform technology that improves the reliability of use and is convenient for maintenance is the technical problem to be solved by the present invention. Summary of the Invention

[0003] The present invention provides a frame-type floating platform and a hydraulic power generation device, which can improve the reliability of use of the frame-type floating platform and is convenient for maintenance.

[0045] As Figures 1 - 9 shown, an embodiment of the present application provides a semi-submersible hydraulic power generation device, including:

[0046] A suspension power generation module, the suspension power generation module includes a frame-type floating platform 11 and a generator 12, the generator 12 is arranged on the frame-type floating platform 11, and a motor shaft of the generator 12 is in transmission connection with the power input shaft 13 through a gearbox 14.

[0047] A water turbine module 2, the water turbine module 2 includes a rotating main shaft 21 and a plurality of water turbine components, the water turbine components include a mounting seat 22 and a plurality of blades 23, the plurality of blades 23 are arranged on the mounting seat 22, a shaft hole is arranged on the mounting seat 22, and the plurality of water turbine components are arranged in sequence from top to bottom, and the rotating main shaft 21 is arranged vertically and inserted into the shaft hole;

[0048] The upper end of the rotating main shaft 21 is connected to the power input shaft 13.

[0049] Specifically, the suspended hydroelectric power generation device provided in this application uses a suspended power generation module for power generation. The generator 12 on the suspended power generation module is located on the frame-type floating platform 11 and is not immersed in water. Thus, it can effectively reduce the occurrence of damage to the generator 12 caused by water ingress due to seal failure, effectively improving the reliability of use of the generator 12 and thereby enhancing the overall reliability of use of the suspended hydroelectric power generation device.

[0050] The water turbine module 2 is connected to the power input shaft 13 through the rotating main shaft 21, and the driving force is transmitted to the power input shaft 13 through the rotating main shaft 21 by multiple water turbine components to drive the generator 12 to generate electricity.

[0051] Among them, in order to improve the reliability of use of the frame-type floating platform 11 to meet the requirement that the buoyancy of the entire frame-type floating platform 11 will not fail in case of local damage, and at the same time, it is also necessary to facilitate maintenance. The following structural improvements are made to the frame-type floating platform 11.

[0052] As Figures 9 - 11 shown, the frame-type floating platform 11 includes a floating frame 111, a plurality of floating components 112, and a platform board 116, and the floating components 112 and the platform board 116 are arranged on the floating frame 111.

[0053] Specifically: the floating frame 111 is a hollow structure, and the floating components 112 are detachably arranged in the corresponding hollow structures. A platform board 116 is also arranged on the upper surface of the floating frame 111, and the platform board covers the hollow structures.

[0054] Specifically, for the frame-type floating platform 11, it needs to meet the installation requirements of supporting the generator 12 at the top and the water turbine module 2 at the bottom. For this reason, the frame-type floating platform 11 adopts a frame structure. That is, floating components 112 are arranged on the floating frame 111 to form the frame-type floating platform 11. The floating frame 111 serves as the installation main body, and the frame structure can improve the structural strength of the frame-type floating platform 11 itself; and the floating components 112 can adopt floating objects in the prior art, such as floating boxes, floating blocks and other physical entities, and the floating components 112 provide the buoyancy required by the frame-type floating platform 11.

[0055] To facilitate the installation and placement of the floating component 112, the floating frame 111 is set as a hollow structure. In this way, the floating component 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 component 112 to improve the overall buoyancy of the frame-type floating platform 11. On the other hand, when the floating component 112 at a specific position is damaged, the floating component 112 in the corresponding hollow structure can be replaced separately to improve the maintenance convenience.

[0056] The platform plate is laid on the upper surface of the floating frame 111 to cover the hollow structure. In this way, the upper surface of the frame-type floating platform 11 becomes flatter, which is convenient for the operator to perform daily maintenance operations on the surface of the frame-type floating platform 11.

[0057] 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-designed 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. In this way, when maintaining 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 frame-type floating platform 11.

[0058] Or, the floating frame 111 is integrally in a circular structure, and a plurality of sockets 117 communicating with the hollow structure are arranged on the outer peripheral circle of the floating frame 111, and the floating component 112 is inserted into the hollow structure through the sockets 117.

[0059] Specifically, since the floating frame 111 is integrally a frame structure, the corresponding formed socket is connected to the corresponding notch structure by using the frame structure on the outer peripheral circle of the floating frame 111. In this way, when assembling the floating component 112 onto the floating frame 111, the floating component 112 can be inserted into the hollow structure from the socket in a plug-in manner.

[0060] Based on the above solution, after the floating component 112 is loaded into the hollow structure, the floating component 112 can also be provided with structures such as fixing ropes or chains to be further connected and fixed to the floating frame 111 to improve the connection reliability.

[0061] Furthermore, a plurality of cable bollards 113 are arranged 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 maintenance ship through the cable bollards 113 after the maintenance ship approaches the frame-type floating platform 11.

[0063] Furthermore, a plurality of cranes 114 are provided on the floating frame 111, and the cranes 114 are arranged near the edge of the floating frame 111.

[0064] Specifically, in order to facilitate the installation and maintenance of the underwater water turbine module 2 on the frame-type floating platform 11, a crane 114 may also be provided on the floating frame 111. During the installation and maintenance process, the crane 114 can hoist the corresponding components and sink them underwater, or hoist the components that need to be replaced underwater out of the water surface.

[0065] In the first embodiment, in order to improve the use reliability of the semi-submersible hydraulic power generation device and improve the power generation efficiency, the following structural improvement design is carried out in this application.

[0066] The first mounting port 110 is provided on the floating frame 111. The suspended power generation module provided in this application further includes a self-balancing assembly 16; the self-balancing assembly 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, and the second rotating shaft is rotatably provided on the first frame 161; the first mounting port 110 is provided on the frame-type floating platform 11, the first frame 161 is located in the first mounting port 110, the first rotating shaft is rotatably provided on the frame-type 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 assembly 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 frame-type floating platform 11 through the first rotating shaft, the first frame 161 can rotate around the axis of the first rotating shaft in the first mounting port 110.

[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 water turbine 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 frame-type floating platform 11 floats on the water surface and will fluctuate due to the water surface undulation. During the shaking process of the frame-type 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 bottom water turbine module 2, so as to effectively utilize the water flow for power generation and 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 the generator 12 in use.

[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 rotating power generation process. As is known to those skilled in the art, under the action of the water flow, the water turbine 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 angle between the axis of the rotating main shaft 21 and the direction relative to its own gravity direction can be considered to be in a substantially vertical state within a set range. The set range of the above angle is to satisfy that the water turbine 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 angle can be 0-30 degrees. The specific range of the 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 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 port 110 to install the self-balancing component 16. The first rotating shaft is installed on the first bearing 115 provided on the frame-type floating platform 11. Correspondingly, the second rotating shaft is installed 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. 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 2, 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 semi-submersible hydroelectric power 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 (the set range of the inclination angle needs to be configured with a counterweight assembly 25 of corresponding weight 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, and the connecting rod 251 passes through the through hole. A plurality of the counterweight blocks 253 are stacked on the supporting portion 252, and 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 circumference 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 will flow through the water flow interval, and the water flow in the water flow interval can cooperate with the rotating counterweight block 253 to further play a role in stabilizing 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. Alternatively, 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 block 253 itself, after a plurality of counterweight blocks 253 are sleeved on the connecting rod 251, two adjacent counterweight blocks 253 are separated by the annular boss. In this way, after the counterweight blocks 253 are sleeved on the connecting rod 251, a water flow interval can be formed between the two counterweight blocks 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 for convenient on-site rapid 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 excessive torque generated by the connecting rod 251 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] Embodiment 3: In order to accurately moor the frame-type floating platform 11, it is necessary to keep the relative inclination positions of multiple anchor chains 33 configured at the bottom of the frame-type floating platform 11 unchanged, and 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 semi-submersible hydroelectric power equipment.

[0088] An anchoring module 3 is further provided at the bottom of the frame-type floating platform 11. The anchoring module 3 includes a dropping frame 31 and a plurality of counterweight components 32. A plurality of anchor chains 33 are arranged on the dropping frame 31, and the counterweight components 32 are arranged on the dropping frame 31.

[0089] The upper end of the anchor chain 33 is connected to the frame-type 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 frame-type floating platform 11 and the corresponding counterweight component 32, and the anchor chain 33 is inclined downward from top to bottom towards the outer side of the frame-type floating platform 11.

[0090] Specifically, during the construction process, the dropping frame 31 and the counterweight components 32 are first put into the seabed together, and then the anchor chain 33 is connected between the frame-type floating platform 11 and the dropping frame 31. Since the structure of the dropping 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 to be unchanged, thereby ensuring that the frame-type floating platform 11 at the top connected by the anchor chains 33 can obtain reliable pulling and positioning by the anchor chains 33. In this way, the relative positions between the anchor chains 33 can be accurately controlled, solving the problem that the positions of the bottom ship anchors on the seabed cannot be controlled by the method of separately dropping the ship anchors, and improving the dropping position accuracy of the anchoring module 3.

[0091] By setting a placement frame 31 on the mooring module 3, a plurality of counterweight components 32 are installed and positioned through the placement frame 31. The relative positions of the plurality of counterweight components 32 are positioned by the placement frame 31. In this way, after the mooring module 3 is placed into the sea and sinks to the seabed, the relative positions of the plurality of counterweight components 32 will not change. Thus, the relative positions of the plurality of anchor chains 33 connected between the counterweight components 32 and the frame-type floating platform 11 can be maintained in a stable state. During use, the plurality of anchor chains 33 can provide pulling forces in multiple directions to the frame-type floating platform 11 floating above. Since the positions of the anchor chains 33 are accurately positioned by the placement frame 31, each anchor chain 33 can play a good role in positioning the frame-type floating platform 11 at the top, enabling the frame-type floating platform 11 to float stably on the sea surface, so as to ensure that the frame-type floating platform 11 can maintain a stable floating state on the water surface, thereby improving the use reliability of the frame-type floating platform 11.

[0092] Furthermore, the placement frame 31 includes a plurality of telescopic beams 311. A locking member 312 is provided on the telescopic beam 311, and the locking member 312 is configured to lock the telescopic beam 311 after the telescopic beam 311 is extended or retracted in place; wherein, the plurality of telescopic beams 311 are connected end to end in sequence.

[0093] Specifically, in order to further improve the use versatility of the mooring module 3 to meet the placement requirements of different depth waters, for the placement frame 31, it is a telescopic frame itself to achieve the expansion and contraction of its own size. Specifically, during the use of the plurality of telescopic beams 311 of the placement frame 31, the length of the telescopic beam 311 can be adjusted according to the depth of the water area where it is located, so as to adjust the relative positions of the respective counterweight components 32, and further ensure the inclination angles of the respective anchor chains 33 to meet the requirements for the stable floating of the frame-type floating platform 11 at the top.

[0094] Furthermore, 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, and the outer sleeve 3111 and the inner core tube 3112 can slide relative to each other. The locking member 312 is provided on the outer sleeve 3111 and is configured to lock the position of the inner core tube 3112 relative to the outer sleeve 3111.

[0095] Specifically, for the telescopic beam 311, in order to meet the requirements of expansion and contraction, 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 achieve the adjustment of the length of the telescopic beam 311.

[0096] 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 process of adjusting the size of the delivery frame 31 for delivery, since the locking member 312 locks the outer sleeve 3111 and the inner core tube 3112 and they will not move relatively, the size of the delivery frame 31 will not be deformed during the delivery process, so as to improve the reliability and convenience of use.

[0097] 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 in the corresponding threaded hole and inserted in the corresponding positioning hole.

[0098] Specifically, the locking member 312 can adopt the way of a locking bolt to lock the positions between the outer sleeve 3111 and the inner core tube 3112. That is, after the relative positions of the outer sleeve 3111 and the inner core tube 3112 are adjusted, the threaded holes will be aligned with the corresponding positioning holes. Then, the locking bolt is tightened so that the locking bolt is inserted into the corresponding positioning hole. In this way, the locking operation can be performed on the positions between the outer sleeve 3111 and the inner core tube 3112.

[0099] 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 and forms a fixed connection part.

[0100] 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.

[0101] 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.

[0102] Furthermore, the counterweight member 32 is a stone-throwing basket, and the stone-throwing basket is configured to hold counterweight stones.

[0103] Specifically, the counterweight component 32 adopts the way 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 thrown 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; alternatively, the stone-throwing basket can be directly welded to the fixed connection part.

[0104] Embodiment 4: In order to improve the waterproof protection ability of the generator 12, the external waterproof structure of the generator 12 is improved.

[0105] A waterproof cover group 15 is further arranged on the frame-type 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 in an annular structure and is arranged on the frame-type floating platform 11. The lower surrounding plate 152 surrounds the periphery of the generator 12. The upper cover body 151 is arranged on the lower surrounding plate 152 and covers above 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 blocks the outside of the connection part formed between the upper cover body 151 and the lower surrounding plate 152.

[0106] Specifically, a waterproof cover group 15 is also arranged 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.

[0107] 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.

[0108] In this way, the generator 12 is covered by the waterproof cover group 15 to block the sea waves during use, so as to play a good role in waterproofing the generator 12.

[0109] Furthermore, a step surface 1513 is formed between the extension part 1511 and the inner wall of the upper cover body 151, and the step surface 1513 abuts against the upper edge of the lower surrounding plate 152.

[0110] Specifically, during the installation process, after the generator 12 is placed in the area surrounded by the lower apron 152, the upper cover 151 can be installed on the lower apron 152. During the installation of the upper cover 151, the upper cover 151 is hoisted above the upper apron and 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.

[0111] Among them, in order to improve the connection reliability between the upper cover 151 and the lower apron 152, after the upper cover 151 and the lower apron 152 are lapped together through the stepped surface 1513, further connection and fixation are required between the upper cover 151 and the lower apron 152. For this purpose, a first connection part 1512 is provided on the upper cover 151, a second connection part 1521 is provided on the lower apron 152, and the first connection part 1512 is connected to the second connection part 1521.

[0112] Specifically, after the upper cover 151 is hoisted onto the lower apron 152, through the connection and cooperation between the first connection part 1512 and the second connection part 1521, the upper cover 151 and the lower apron 152 are firmly connected together to improve the connection reliability during use.

[0113] There can be various structural forms for the manifestation entities of the first connection part 1512 and the second connection part 1521. For example: the first connection part 1512 is a plurality of connection columns provided at the lower edge of the upper cover 151, the lower end of the connection column is provided with a head, and the outer peripheral dimension of the head is larger than the outer peripheral dimension of the connection column; the second connection 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 connection column is inserted into the strip-shaped hole, and the head is arranged below the strip-shaped hole and is configured to limit the connection column from disengaging from the strip-shaped hole.

[0114] Specifically, connection columns are provided at the lower part of the upper cover 151, and correspondingly, strip-shaped holes are provided at the upper part of the lower apron 152. During the assembly process, after the upper cover 151 is hoisted above the lower apron 152, the connection columns are aligned with the corresponding strip-shaped holes, and then, after the connection columns are inserted into the strip-shaped holes, the upper cover 151 is rotated by a certain angle so that the heads of the connection columns move to the small-size ends of the strip-shaped holes to prevent the connection columns from disengaging from the strip-shaped holes. In this way, the upper cover 151 can be installed on the lower apron 152.

[0115] Or, the first connection part 1512 is a support beam provided on the upper cover 151, the support beam has an arc-shaped structure, insertion interfaces are formed at both ends of the support beam, and the second connection part 1521 is an insertion protrusion provided on the lower apron 152, and the insertion protrusion is inserted into the corresponding insertion interface.

[0116] Specifically, during the assembly process, after hoisting the upper cover 151 above the lower surrounding plate 152, align the insertion protrusion with the insertion opening. Then, the stepped surface 1513 of the upper cover 151 abuts against the lower surrounding plate 152 so that the insertion protrusion is inserted into the insertion opening, thereby installing the upper cover 151 on the lower surrounding plate 152. Preferably, the insertion protrusion and the support beam can be further connected by bolts to improve the connection reliability between the upper cover 151 and the lower surrounding plate 152.

[0117] Among them, for the waterproof cover group 15, in order to reduce wind resistance and improve structural strength, the upper cover 151 is of a hemispherical structure, while for the lower surrounding plate 152, it can be of a cylindrical structure or a hemispherical structure.

[0118] In addition, an indicator light 17 is also provided on the upper cover 151. The indicator light 17 can play an indicating role when the semi-submersible hydroelectric power equipment floats in the sea at night, so as to improve the use safety.

[0119] Embodiment Five: 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 arranged on the mounting seat 22.

[0120] Since the blades 23 are frequently subjected to the reciprocating force of the water flow, the blades 23 are prone to damage only relying on the support of the hinged part. For this reason, a plurality of limiting stoppers 24 are further provided on the mounting seat 22, and the limiting stoppers 24 are arranged between two adjacent blades 23.

[0121] Specifically, during the use process, the water flow is used to drive the blades 23 to drive the rotation of the rotating main shaft 21. And, during the rotation of the blades 23 following the rotating main shaft 21, the driving force of the water flow on the blades 23 is different at different positions.

[0122] When the blades 23 are driven by the water flow to drive the rotation of the rotating main shaft 21, the limiting stoppers 24 can play a supporting role for the blades 23. Furthermore, when the blades 23 are under force, the blades 23 are supported by the limiting stoppers 24, which can reduce the force on the hinged part of the blades 23 and improve the use reliability.

[0123] When the blades 23 are driven by the water flow to block the normal rotation of the rotating main shaft 21, the limiting stoppers 24 can also play a supporting role for the blades 23, further improving the use reliability of the blades 23.

[0124] By providing a limiting stop 24 on the mounting base 22, the blade 23 is located between 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 hits the blade 23 to generate a driving force on the rotating main shaft 21, this blade 23 will abut against the corresponding limiting stop 24 on that side to utilize the limiting stop to support the blade 23. In addition, for the blade 23 where the water flow hits the blade 23 to generate a driving force on the rotating main shaft 21, this blade 23 can also be supported by the corresponding side, so that during the rotation of the blade 23, an additional supporting force can be provided by the limiting stop 24, reducing the force on the hinged part of the blade 23, thereby reducing the frequent repeated stress on the hinged part of the blade 23 and preventing damage, improving the reliability of the blade 23 in use and thus enhancing the overall reliability of the suspended hydroelectric power generation device.

[0125] Among them, a space for restricting the rotation angle of the blade 23 is formed between two adjacent limiting stops 24.

[0126] In one 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.

[0127] 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 pass through the blade 23 more smoothly and improving the energy conversion efficiency of the entire device.

[0128] 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, 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.

[0129] In another embodiment, one end of the limiting stop 24 is fixedly installed on the rotating main shaft 21, and the other end of the limiting stop 24 is arranged in a suspended manner.

[0130] Specifically, one end of the limit stop member 24 is fixed on 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 velocities, thereby protecting the rotating main shaft 21 and the blade 23. The limit 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.

[0131] Furthermore, a support surface 241 is formed on one side wall of the limit 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 limit stop member 24 forms a second guiding surface 242, and the second guiding surface 242 is an arc-shaped convex surface.

[0132] Specifically, the limit 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 water flow to drive the rotating main shaft 21 to rotate, the first guiding surface 232 of the blade 23 can be in good contact with the support surface 241 of the limit stop member 24, so as to provide stable support through the support surface 241 and prevent the blade 23 from shifting or deforming during rotation. The design of the second guiding surface 242 helps to further optimize the flow path of the water flow, reduce the water flow resistance, and improve the overall efficiency of the device.

[0133] Through the design of the limit 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.

[0134] Furthermore, in order to facilitate the subsequent separate maintenance of each water turbine component, the rotating main shaft 21 includes a plurality of rotating sub-shafts 211. The plurality of rotating sub-shafts 211 are arranged coaxially, and two adjacent rotating sub-shafts 211 are detachably connected together. The rotating sub-shaft 211 located at the top is detachably connected to the power input shaft 13;

[0135] Each rotating sub-shaft 211 is provided with a water turbine component.

[0136] Specifically, each rotating sub-shaft 211 is correspondingly provided with an independent water turbine component. During use, when a certain water turbine component is damaged and needs to be replaced and repaired, the rotating sub-shaft 211 corresponding to the damaged water turbine component can be detached together, and then the damaged water turbine component can be replaced separately to improve the convenience of maintenance.

[0137] Embodiment Six. In another embodiment of the present application, a maintenance method for a semi-submersible hydroelectric power generation device is further provided, including:

[0138] 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 upper frame-type floating platform 11. Then, disconnect the rotating shaft 211 of the water turbine assembly to be disassembled from the power input shaft 13 and the rotating shaft 211 of the water turbine assembly below to disassemble and remove the water turbine assembly to be disassembled; place the new water turbine assembly between the frame-type floating platform 11 and the water turbine assembly below again, and connect the rotating shaft 211 on the new water turbine assembly between the power input shaft 13 and the rotating shaft 211 of the water turbine assembly below.

[0139] Specifically, when the water turbine module 2 at the topmost part needs to be disassembled and replaced, it is necessary to use a suspension device (such as a steel chain or a steel wire rope) to suspend and connect the mounting base 22 of the water turbine module 2 below the water turbine module 2 to be disassembled with the upper frame-type floating platform 11. 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, it can ensure the stability of the water turbine module 2 below and the entire frame-type floating platform 11 when disassembling the water turbine module 2 at the topmost part, and prevent structural instability problems caused by disassembly.

[0140] Gradually disconnect the connection between the rotating shaft 211 of the water turbine module 2 to be disassembled and the power input shaft 13 and the rotating shaft 211 of the water turbine module 2 below, then the damaged water turbine module 2 can be taken out. Then, place the new water turbine module 2 between the frame-type floating platform 11 and the water turbine module 2 below, and ensure that its rotating shaft 211 is correctly docked with the power input shaft 13 and the rotating shaft 211 of the water turbine module 2 below.

[0141] After the replacement is completed, disassemble the suspension device.

[0142] During the process of replacing the water turbine module 2 in the middle, first, suspend and connect the mounting base 22 of the water turbine module 2 below the water turbine module 2 to be disassembled with the mounting base 22 of the water turbine module 2 above. Then, disconnect the rotating shaft 211 of the water turbine module 2 to be disassembled from the rotating shafts 211 of the upper and lower water turbine modules 2 to disassemble and remove the water turbine module 2 to be disassembled; place the new water turbine module 2 between the upper and lower water turbine modules 2 again, and connect the rotating shaft 211 of the new water turbine module 2 between the rotating shafts 211 of the upper and lower water turbine modules 2.

[0143] Specifically, during the process of replacing the middle water wheel module 2, a suspension device is used to suspend and connect the mounting seat 22 of the water wheel module 2 below the water wheel module 2 to be disassembled with the mounting seat 22 of the water wheel module 2 above. This step ensures the stability of the upper and lower part structures after the middle water wheel module 2 is disassembled, preventing structural instability caused by disassembly. Then, gradually disconnect the connection between the rotating sub-shaft 211 of the water wheel module 2 to be disassembled and the rotating sub-shafts 211 of the upper and lower water wheel modules 2, and then move the water wheel module 22 to be disassembled out from between the upper and lower water wheel modules 2. The operation should be carried out slowly to ensure smooth movement.

[0144] After the middle water wheel module 2 is removed, the suspension device connects the two spaced water wheel modules 2 together to prevent the lower water wheel module 2 from sinking underwater. Finally, place the new water wheel module 2 between the upper and lower water wheel modules 2 and ensure that its rotating sub-shaft 211 is correctly docked between the rotating sub-shafts 211 of the upper and lower water wheel modules 2.

[0145] After the replacement is completed, disassemble the suspension device.

[0146] During the process of replacing the bottom water wheel module 2, disconnect the connection between the rotating sub-shaft 211 of the water wheel module 2 to be disassembled and the rotating sub-shaft 211 of the upper water wheel module 2 to remove the water wheel module 2 to be disassembled; then place the new water wheel module 2 below the upper water wheel module 2 again and connect the rotating sub-shaft 211 of the new water wheel module 2 to the rotating sub-shaft 211 of the upper water wheel module 2.

[0147] Specifically, during the process of replacing the bottom water wheel module 2, a suspension device is used to suspend and connect the counterweight assembly 25 with the mounting seat 22 of the water wheel module 2 below the water wheel module 2 to be disassembled. Then, gradually disconnect the connection between the rotating sub-shaft 211 of the water wheel module 2 to be disassembled and the rotating sub-shaft 211 of the upper water wheel module 2 to ensure the safety of each operation. After the water wheel module 2 to be disassembled is removed, place the new water wheel module 2 below the upper water wheel module 2 and ensure that its rotating sub-shaft 211 is correctly docked with the rotating sub-shaft 211 of the upper water wheel module 2. Finally, reconnect the counterweight assembly 25 to the rotating sub-shaft 211 of the new water wheel module 2.

[0148] After the replacement is completed, disassemble the suspension device.

[0149] The above is only the specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by those skilled in the art within the technical scope disclosed by the present invention should be covered within the protection scope of the present invention.
