[0017] like Figure 1-Figure 6 As shown, an embodiment of the present application provides a hydroelectric power generation device, comprising: The power generation module includes a generator 12 .

[0018] A driving module 2, the driving module 2 comprises a rotating main shaft 21 and a water wheel assembly, the water wheel assembly comprises a plurality of blades 23, the blades comprise a mounting frame 231 and a plurality of baffles 232, the mounting frame 231 is provided with a plurality of through openings 233, the baffles 232 are hinged on the mounting frame 231 and arranged at the corresponding through openings 233; The baffle 232 is configured to be located at the upstream surface of the blade to close the through-hole 233, and the blade is also configured to be located at the downstream surface of the blade to open the through-hole 233; The mounting frame 231 is fixedly mounted on the rotating main shaft 21 , and the rotating main shaft 21 is transmission-connected to the generator 12 .

[0019] Specifically, in actual use, the blades 23 in the driving module 2 will be put under the water surface, so as to utilize the effect of water flow on the blades 23 to drive the rotating main shaft 21 to rotate, and the rotating rotating main shaft 21 will drive the generator 12 to generate electricity.

[0020] Since the rotating main shaft 21 is arranged vertically in the water, during the rotation of the blades 23, the blades 23 will alternately generate a driving force and a blocking force on the rotating main shaft 21. In order to increase the driving force generated by the blades 23 and reduce the blocking force generated by the blades, the structure of the blades 23 is improved, that is, the blades 23 include a mounting frame 231 and a baffle 232 arranged on the mounting frame 231. The mounting frame 231 is provided with a through hole 233 to meet the requirement that water flows through the mounting frame 231, and the baffle 232 opens and closes the through hole 233 according to the state change of the force generated by the blades on the rotating main shaft.

[0021] Specifically, when the movement direction of the blade 23 is the same as the direction of the water flow, the blade 23 will generate a driving force on the rotating main shaft 21. At this time, the baffle on the blade 23 will be located on the front surface of the blade. Under the action of the water flow, the baffle will cover the through hole 233 on the mounting frame 231, so that the blade can have a sufficiently large effective area to contact the water flow to generate thrust, and then the water flow can maximize the thrust generated on the blade 23 to drive the rotating main shaft 21 to rotate.

[0022] When the movement direction of the blade 23 is opposite to the direction of the water flow, the blade 23 will generate a blocking force on the rotating main shaft 21. At this time, the baffle on the blade 23 will be located on the back flow side of the blade 23. Under the action of the water flow, the baffle will leave the through-hole 233 and then open the through-hole 233 on the mounting frame 231 to reduce the effective area generated by the blade and the water flow. In this way, the blocking force of the water flow on the blade 23 can be minimized.

[0023] By providing a plurality of through openings 233 on the mounting frame 231, and correspondingly configuring baffles 232 for opening and closing, during use, the blades will drive the rotating main shaft to rotate under the driving action of the water flow, so that the baffles 232 are alternately located on the upstream side and the downstream side of the blades during the rotation of the blades. When the baffle 232 is located on the upstream side of the blades, the baffle 232 will close the through openings 233, so that the water flow applies pressure to the baffle 232 to drive the rotating main shaft to rotate, and when the baffle 232 is located on the downstream side of the blades, the baffle 232 will open under the action of the water flow. Through opening 233, in this way, during the rotation process, the water flow driving force exerted on the blades in the same direction as the water flow is greater than the water flow driving force exerted on the blades in the opposite direction to the water flow, so that a larger pressure difference can be formed on both sides of the rotating main shaft to increase the rotation speed of the rotating main shaft and improve the power generation efficiency; and, the blade mounting frame 231 remains fixed with the rotating main shaft during the rotation process, and only a number of baffles 232 on different blades rotate under the influence of the water flow, thereby improving the reliability of use, and the overall structure is simpler and convenient for maintenance, thereby improving the reliability of use.

[0024] Furthermore, in the process of the baffle 232 being impacted by the water flow to open the through-opening 233, in order to control the opening angle of the baffle 232, a plurality of limiting components (not shown) are further provided on the mounting frame 231, and the limiting components are arranged on the outer sides of the corresponding baffles 232; the limiting components are configured to limit the rotation angle of the baffle 232 to open the through-opening 233.

[0025] Specifically, during the rotation of the blade 23, when the movement direction of the blade 23 is opposite to the flow direction of the water flow, the baffle 232 on the blade 23 will be flushed open by the water flow, and the water flow will flow through the mounting frame 231 of the blade 23 via the through-hole 233. The baffle 232 is flipped open by the water flow, and the baffle 232 is restricted by the limiting component to control the flipping angle of the baffle 232.

[0026] The limiting component is a limiting rod, one end of which is fixedly disposed on the mounting frame 231 , and the other end of which is arranged on the outer side of the baffle 232 .

[0027] Alternatively, the limiting component is a limiting plate, one end of which is fixedly disposed on the mounting frame 231 , and the other end of which is arranged on the outer side of the baffle 232 .

[0028] In addition, in order to facilitate the installation of the baffle 232 , the top of the baffle 232 is installed on the installation frame 231 through a hinge 234 , or the side of the baffle 232 is installed on the installation frame 231 through a hinge 234 .

[0029] Furthermore, in order to reduce the overall height of a single blade and fully utilize the water depth to improve the power generation efficiency, a plurality of water wheel assemblies are provided on the rotating main shaft, and the plurality of water wheel assemblies are arranged in sequence and spaced apart along the length direction of the rotating main shaft.

[0030] Specifically, a plurality of water wheel assemblies may be arranged on the same rotating main shaft along its length direction, and then the plurality of water wheel assemblies may be driven by water flow to perform efficient power generation operations.

[0031] Furthermore, in order to reduce the difficulty of processing and installation, the water wheel assembly also includes a plurality of connecting frames, and the connecting frames are arranged on the rotating main shaft, and the mounting frame 231 is connected to the rotating main shaft through the connecting frames.

[0032] Specifically, the blade as a whole adopts the mounting frame 231 as the main structure. The mounting frame 231 can be processed by conventional methods such as steel pipe welding or casting. The overall structure of the mounting frame 231 is simple, and there is no need to consider the streamlined design of the blade. It only needs to arrange a corresponding number of through holes 233 to reduce the blocking force generated by the blade 23.

[0033] The mounting frame 231 can be fixedly connected to the rotating main shaft via a connecting frame, and the connecting frame can be welded between the mounting frame 231 and the rotating main shaft, or the connecting frame can be fixed between the mounting frame 231 and the rotating main shaft by bolt fastening or the like.

[0034] Based on the above technical solution, optionally, in actual use, in order to facilitate the installation of the generator 12 , the power generation module includes a floating platform 11 , and the generator 12 is arranged on the floating platform 11 .

[0035] Specifically, the suspended hydroelectric power generation device provided in the present application adopts 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, thereby effectively reducing the damage caused by water ingress due to sealing failure of the generator 12, effectively improving the reliability of the use of the generator 12, thereby improving the overall reliability of the suspended hydroelectric power generation device.

[0036] Embodiment 2, as Figure 1-Figure 8 As shown, in order to improve the reliability of hydroelectric power generation equipment and increase power generation efficiency, the present application carries out the following structural improvement design.

[0037] The power generation module provided in the present application also includes a self-balancing component 16; the self-balancing component includes a first frame 161 and a second frame 162, the first frame 161 is provided with a first rotating shaft, the second frame 162 is provided with a second rotating shaft, the axis of the first rotating shaft and the axis of the second rotating shaft are perpendicular to each other, and the second rotating shaft is rotatably arranged 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 arranged on the floating platform 11, the second frame 162 is provided with a power input shaft 13, and the generator 12 is fixed on the second frame 162.

[0038] Specifically, the self-balancing assembly is provided 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 of 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 around the axis of the first rotating shaft in the first installation port 110.

[0039] The generator 12 is mounted on the second frame 162 and connected to the power input shaft 13 on the second frame 162, and the drive module 2 is connected to the lower end of the power input shaft 13 through the rotating main shaft 21. During normal power generation, the floating platform 11 floats on the water surface and will shake up and down due to the fluctuation of the water surface. 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 basically vertical under the gravity of the bottom drive module 2, so as to effectively use the water flow to generate electricity, so as 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 the generator 12.

[0040] It should be noted that the "basic vertical" mentioned in the present application refers to the state that the rotating main shaft 21 is in a vertical arrangement during the rotation and power generation process. It is known to those skilled in the art that under the action of water flow, the driving module 2 is bound to be affected by the water flow and cause the rotating main shaft 21 to tilt at a certain angle. The above-mentioned "basic vertical" means that the angle between the axis of the rotating main shaft 21 and the direction relative to its own gravity can be considered to be basically vertical within a set range. The setting range of the above-mentioned angle is to ensure that the driving module 2 can drive the rotating main shaft 21 to generate electricity normally and efficiently under the water flow. For example, the angle can be 0-30 degrees. There is no limitation on the specific range of the angle.

[0041] In one embodiment, the first frame 161 and the second frame 162 are arranged transversely, and the first frame 161 surrounds the periphery of the second frame 162 .

[0042] Specifically, the first frame 161 and the second frame 162 are arranged horizontally to fully utilize the space of the first installation opening 110 to install the self-balancing assembly 16. The first shaft is installed on the first bearing 115 provided on the floating platform 11, and correspondingly, the second shaft is installed on the second bearing on the first frame 161.

[0043] In one embodiment, a second mounting opening 163 is provided on the second frame 162, a step mounting surface 164 is provided in the second mounting opening 163, a bottom ring 165 is provided on the step mounting surface 164, and a first circular slide groove (not marked) is provided on the upper surface of the bottom ring 165; a shaft ring 131 is provided on the power input shaft 13, and a second circular slide groove is provided on the lower surface of the shaft ring 131; the self-balancing assembly 16 also includes a circular ring frame 166 and a plurality of support balls 167, a plurality of limiting through holes (not shown) are provided on the circular ring frame 166, and the support balls 167 are located in the limiting through holes; the circular ring frame 166 is located between the bottom ring 165 and the shaft ring 131, and the support balls 167 are located between the first circular slide groove and the second circular slide groove.

[0044] Specifically, in order to improve the installation reliability of the power input shaft 13, a shaft ring 131 is further provided on the power input shaft 13, and in order to ensure that the power input shaft 13 can rotate smoothly on the second frame 162, a step surface 1513 is further provided on the second frame 162 to install the bottom ring 165. The shaft 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 shaft ring 131 to rotate.

[0045] In actual use, the power input shaft 13 can define its installation position in the second installation opening 163 through the shaft ring 131 , and utilize the support ball 167 under the shaft ring 131 to ensure smooth rotation driven by the water channel module.

[0046] In order to ensure that the rotating main shaft 21 can rotate in a substantially vertical state during use, and to ensure that the rotating main shaft 21 can be quickly and automatically reset after being tilted due to excessive water flow impact, the following improvements are made to the hydropower generation equipment.

[0047] A weight assembly 25 is disposed at the lower end of the rotating main shaft 21 . The weight assembly 25 is configured to apply a downward pulling force to the lower end of the rotating main shaft 21 .

[0048] 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 maintain the stability of the rotating main shaft 21, so that the rotating main shaft 21 can be in a basically vertical state below the water surface or the inclination angle is within a set range (regarding the setting range of the inclination angle, it is necessary to configure the counterweight assembly 25 of corresponding weight according to the flow velocity of the water below the water surface, which is not limited here).

[0049] 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 the size of the connecting rod 251. A through hole is provided on the counterweight block 253. The connecting rod 251 passes through the through hole. The plurality of 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.

[0050] Specifically, in order to facilitate the assembly and installation of the counterweight assembly 25, multiple counterweight blocks 253 are used to meet the weight requirements of the configuration assembly. According to usage requirements, a corresponding number of counterweight blocks 253 can be configured and connected to the bottom of the rotating main shaft 21 through a connecting rod 251.

[0051] Furthermore, the counterweight block 253 is in a disc-shaped structure, and a water flow interval is formed between two adjacent counterweight blocks 253 .

[0052] 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, so that the arc surface formed by the outer circumference of the counterweight block 253 is used to reduce the resistance of the water flow.

[0053] At the same time, a water flow gap is further formed between two adjacent counterweight blocks 253. During use, water will flow through the water flow gap, and the water flowing in the water flow gap can cooperate with the rotating counterweight block 253 to further stabilize the posture of the rotating main shaft 21, so that the rotating shaft can maintain a normal power generation state and generate efficient power under the drive of the water flow.

[0054] Furthermore, in order to form a water flow interval between two counterweights 253, a spacer ring can be placed between two adjacent counterweights 253, and the spacer ring can separate the two counterweights 253. Alternatively, an annular boss (not shown) is provided around the through hole on the counterweight 253; the upper counterweight 253 abuts against the annular boss of the lower counterweight 253 when two counterweights 253 are adjacent to each other.

[0055] Specifically, by configuring the counterweight block 253 itself with an annular boss, after multiple counterweight blocks 253 are put on the connecting rod 251, two adjacent counterweight blocks 253 are separated by the annular boss. In this way, after the counterweight block 253 is put on the connecting rod 251, a water flow gap can be formed between the two counterweight blocks 253 through the annular boss to facilitate assembly.

[0056] 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 a connecting device such as a coupling to facilitate rapid on-site assembly.

[0057] 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 prevent the connecting rod 251 from 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 generate a certain amount of deflection relative to the rotating bearing. In order to accurately anchor the floating platform 11, it is necessary to keep the multiple anchor chains 33 arranged at the bottom of the floating platform 11 at a relatively unchanged tilted position. However, the method of dropping anchors underwater cannot accurately control the position of each anchor on the seabed. In order to solve this problem, the following structural improvements are made to the seabed anchoring method of hydropower equipment.

[0058] The bottom of the floating platform 11 is also provided with an anchor module 3, which includes a delivery frame 31 and a plurality of counterweight components 32, a plurality of anchor chains 33 are provided on the delivery frame 31, and the counterweight components 32 are provided on the delivery frame 31; The upper end of the anchor chain 33 is connected to the floating platform 11 . The anchor chain 33 is arranged obliquely between the floating platform 11 and the corresponding counterweight component 32 . The anchor chain 33 is inclined from top to bottom toward the outer side of the floating platform 11 .

[0059] Specifically, during the construction process, the delivery frame 31 and the counterweight component 32 are first dropped to the seabed together, and then the anchor chain 33 is connected between the floating platform 11 and the delivery frame 31. Since the structure of the delivery frame 31 itself has accurately defined the positions of different counterweight components 32, the bottom connection position of the anchor chain 33 can be determined to be unchanged for different anchor chains 33, thereby ensuring that the floating platform 11 at the top connected to the anchor chain 33 can obtain reliable pulling positioning of the anchor chain 33, so that the relative positions of the anchor chains 33 can be accurately controlled, solving the problem of the position of the bottom anchor on the seabed being uncontrollable due to the method of delivering anchors separately, and improving the delivery position accuracy of the mooring module 3.

[0060] By setting a launching frame 31 on the mooring module 3, a plurality of counterweight components 32 are installed and positioned through the launching frame 31, and the relative positions of the plurality of counterweight components 32 are positioned by the launching frame 31. In this way, after the mooring module 3 is launched into the sea and sinks to the seabed, the relative positions of the plurality of counterweight components 32 will not change. In this way, the relative positions of the plurality of anchor chains 33 connected between the counterweight components 32 and the floating platform 11 can be kept in a stable state. During use, the plurality of anchor chains 33 can provide multi-directional pulling force to the floating platform 11 floating above. Since the position of the anchor chain 33 is accurately positioned by the launching frame 31, each anchor chain 33 can play a good positioning role on the top floating platform 11, so that the floating platform 11 can float stably on the sea surface, so as to ensure that the floating platform 11 can maintain a stable floating state on the water surface, thereby improving the reliability of the use of the floating platform 11.

[0061] Furthermore, the delivery frame 31 includes a plurality of telescopic beams 311, and a locking member 312 is provided on the telescopic beams 311, and the locking member 312 is configured to lock the telescopic beams 311 after the telescopic beams 311 are telescoped into place; wherein the plurality of telescopic beams 311 are connected end to end in sequence.

[0062] Specifically, in order to further improve the versatility of the mooring module 3 and meet the requirements of launching in waters of different depths, the launching frame 31 itself is a telescopic frame to achieve the expansion and contraction of its own size. Specifically, during use, the multiple telescopic beams 311 of the launching frame 31 can adjust the length of the telescopic beams 311 according to the depth of the waters, so as to adjust the relative position of each counterweight component 32, thereby ensuring that the inclination angle of each anchor chain 33 meets the requirement of stable floating of the top floating platform 11.

[0063] Furthermore, the telescopic beam 311 includes an outer sleeve 3111 and an inner core tube 3112. The outer sleeve 3111 is sleeved on the outside of 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.

[0064] Specifically, for the telescopic beam 311 , in order to meet the telescopic requirement, an outer sleeve 3111 is matched with an inner core tube 3112 , and the outer sleeve 3111 can move relative to the inner core tube 3112 to achieve adjustment of the length of the telescopic beam 311 .

[0065] At the same time, 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 of the delivery frame 31 after the size is adjusted, the outer sleeve 3111 and the inner core tube 3112 are locked by the locking member 312 so that relative movement does not occur. In this way, the size of the delivery frame 31 will not be deformed during the delivery process, thereby improving the reliability and convenience of use.

[0066] Furthermore, the outer sleeve 3111 is provided with a plurality of threaded holes (not shown in the figure), and the inner core tube 3112 is provided with a plurality of positioning holes (not shown in the figure). 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, which is threadedly connected in the corresponding threaded hole and inserted in the corresponding positioning hole.

[0067] Specifically, the locking member 312 can use a locking bolt to lock the position between the outer sleeve 3111 and the inner core tube 3112, that is, after adjusting the relative position of the outer sleeve 3111 and the inner core tube 3112, the threaded hole will be aligned with the corresponding positioning hole, and then, the locking bolt is tightened so that the locking bolt is inserted into the corresponding positioning hole, so that the position between the outer sleeve 3111 and the inner core tube 3112 can be locked.

[0068] More preferably, 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 portion.

[0069] Specifically, the delivery frame 31 formed by connecting the telescopic beams 311 may be in the shape of an equilateral triangle or a rectangle, so that the ends of two adjacent telescopic beams 311 may be fixedly connected together by welding.

[0070] After the ends of the two telescopic beams 311 are welded together, a fixed connection portion is formed, and the counterweight component 32 can be connected to the corresponding fixed connection portion. For example, the counterweight component 32 can be connected to the counterweight component 32 through a chain, or the counterweight component 32 can be welded to the fixed connection portion through a connecting beam.

[0071] Still further, the counterweight component 32 is a slingshot basket, which is configured to hold counterweight stones.

[0072] Specifically, the counterweight component 32 is in the form of a stone throwing basket. After the mooring module 3 is transported to the designated waters, a certain amount of stones are thrown into the stone throwing basket, and then the mooring module 3 is thrown into the water. The stone throwing basket is arranged below the throwing frame 31, for example, the stone throwing basket is suspended on the fixed connection part through a chain; or the stone throwing basket can be directly welded to the fixed connection part.

[0073] Based on the above technical solution, optionally, the floating platform 11 includes a floating frame 111 and a floating component 112 , the floating frame 111 is provided with a first installation port 110 , and the floating component 112 is provided on the floating frame 111 .

[0074] Specifically, the floating platform 11 needs to meet the installation requirements of the generator 12 on the top of the floating support and the driving module 2 at the bottom. For this reason, the floating platform 11 adopts a frame structure. That is, a floating component 112 is arranged on the floating frame 111 to form the floating platform 11. The floating frame 111 is used as the installation body, and the frame structure can improve the structural strength of the floating platform 11 itself; and the floating component 112 can adopt floating objects in the prior art, such as floating boxes, floating blocks and other performance entities, and the floating force required by the floating platform 11 is improved by the floating component 112.

[0075] Furthermore, the floating frame 111 is a hollow structure, and the floating component 112 is arranged in the hollow structure.

[0076] Specifically, in order to facilitate the installation and placement of the floating components 112, the floating frame 111 is set as a hollow structure, so that the floating components 112 can be built into the hollow structure of the floating frame 111. On the one hand, the floating components 112 can be arranged at various positions of the floating frame 111 to improve the overall buoyancy of the floating platform 11. On the other hand, when the floating components 112 at a specific position are damaged, the floating components 112 in the corresponding hollow structure can be replaced separately to improve the convenience of maintenance.

[0077] In order to improve the flatness of the upper surface of the floating platform 11 , a platform plate (not shown) may be further provided on the upper surface of the floating frame 111 , and the platform plate covers the hollow structure.

[0078] 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 smoother, thereby facilitating operators to perform daily maintenance operations on the surface of the floating platform 11 .

[0079] The platform plate may be an integral plate (e.g., multiple iron plates are welded together and fixed on the floating frame 111). Alternatively, the platform plate may be composed of multiple separately designed iron plates, each of which covers the corresponding hollow structure; and the iron plate may be connected to the floating frame 111 in a hinged manner, so that when the floating component 112 at the corresponding position is repaired, the iron plate at the corresponding position may be opened to facilitate the operator to repair and replace the floating component 112 on the floating platform 11.

[0080] Furthermore, a plurality of cable piles 113 are provided on the floating frame 111 , and the cable piles 113 are arranged close to the edge of the floating frame 111 .

[0081] Specifically, the cable piles 113 can be used to fix the cables on the maintenance ship after the maintenance ship approaches the floating platform 11.

[0082] Furthermore, a plurality of cranes 114 are disposed on the floating frame 111 , and the cranes 114 are arranged close to the edge of the floating frame 111 .

[0083] Specifically, in order to facilitate the installation and maintenance of the underwater drive module 2 on the floating platform 11, a crane 114 can also be set on the floating frame 111. The crane 114 can hoist the corresponding components and sink them underwater during the installation and maintenance process, and can also hoist the underwater components that need to be replaced out of the water.

[0084] In order to improve the waterproof protection capability of the generator 12 , the external waterproof structure of the generator 12 is improved.

[0085] A waterproof cover group 15 is also provided on the floating platform 11, and the waterproof cover group 15 includes an upper cover body 151 and a lower enclosure plate 152. The lower enclosure plate 152 is annular in structure and is provided on the floating platform 11. The lower enclosure plate 152 surrounds the periphery of the generator 12. The upper cover body 151 is provided on the lower enclosure plate 152 and covers the top of the generator 12. The lower edge of the upper cover body 151 forms an extension portion 1511, and the extension portion 1511 extends downward and blocks the outer side of the connection portion formed between the upper cover body 151 and the lower enclosure plate 152.

[0086] Specifically, a waterproof cover group 15 is also provided on the second frame 162 to shield and protect the generator 12 on the second frame 162 through the waterproof cover group 15. The lower enclosure 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 enclosure 152 to cover the generator 12.

[0087] At the same time, since the lower edge of the upper cover body 151 is also provided with an extension portion 1511, the extension portion 1511 can effectively shield the connection portion between the upper cover body 151 and the lower enclosure plate 152. During use, even if the waves hit the waterproof cover group 15, the extension portion 1511 can effectively prevent seawater from entering the waterproof cover group 15 through the connection portion between the upper cover body 151 and the lower enclosure plate 152.

[0088] In this way, the generator 12 is covered by the waterproof cover assembly 15 , so that the waterproof cover assembly 15 can block the waves during use, thereby achieving a good waterproof effect on the generator 12 .

[0089] Furthermore, a step surface 1513 is formed between the extension portion 1511 and the inner wall of the upper cover body 151 , and the step surface 1513 abuts against the upper edge of the lower enclosure plate 152 .

[0090] Specifically, during the installation process, after the generator 12 is placed in the area surrounded by the lower enclosure 152, the upper cover 151 can be installed on the lower enclosure 152. During the installation of the upper cover 151, the upper cover 151 is hoisted above the upper enclosure and overlapped on the upper edge of the upper enclosure through the step surface 1513, so that the upper cover shell can be installed on the upper enclosure.

[0091] In order to improve the connection reliability between the upper cover 151 and the lower enclosure 152, after the upper cover 151 and the lower enclosure 152 are overlapped together through the step surface 1513, the upper cover 151 and the lower enclosure 152 need to be further connected and fixed. To this end, the upper cover 151 is provided with a first connection portion 1512, and the lower enclosure 152 is provided with a second connection portion 1521, and the first connection portion 1512 and the second connection portion 1521 are connected together.

[0092] Specifically, after the upper cover body 151 is hoisted onto the lower enclosure plate 152, the first connection portion 1512 is connected and matched with the second connection portion 1521, so that the upper cover body 151 and the lower enclosure plate 152 are firmly connected together to improve the connection reliability during use.

[0093] The first connection part 1512 and the second connection part 1521 may be represented by various structural forms. For example, the first connection part 1512 is a plurality of connection columns arranged at the lower edge of the upper cover 151, and the lower end of the connection column is provided with a terminal, and the outer circumference of the terminal is larger than the outer circumference of the connection column; the second connection part 1521 is a strip hole formed on the lower enclosure 152, and the opening size of the strip hole decreases along the length direction; the connection column is inserted into the strip hole, and the terminal is arranged below the strip hole and is configured to restrict the connection column from being separated from the strip hole.

[0094] Specifically, a connecting column is provided at the lower part of the upper cover 151, and correspondingly, a strip hole is provided at the upper part of the lower enclosure 152. During the assembly process, after the upper cover 151 is hoisted above the lower enclosure 152, the connecting column is aligned with the corresponding strip hole, and then, after the connecting column is inserted into the strip hole, the upper cover 151 is rotated at a certain angle so that the end of the connecting column moves to the end of the small size of the strip hole to prevent the connecting column from escaping from the strip hole. In this way, the upper cover 151 can be installed on the lower enclosure 152.

[0095] Alternatively, the first connection part 1512 is a support beam arranged on the upper cover body 151, the support beam has an arc-shaped structure, and the two ends of the support beam form an insertion interface. The second connection part 1521 is a plug-in protrusion arranged on the lower enclosure 152, and the plug-in protrusion is inserted into the corresponding plug-in interface.

[0096] Specifically, during the assembly process, after the upper cover 151 is hoisted above the lower enclosure 152, the plug-in protrusion is aligned with the plug-in port, and then the step surface 1513 of the upper cover 151 abuts against the lower enclosure 152 so that the plug-in protrusion is inserted into the plug-in port, so as to achieve the installation of the upper cover 151 on the lower enclosure 152. Preferably, the plug-in protrusion and the support beam can be further connected by bolts to improve the connection reliability between the upper cover 151 and the lower enclosure 152.

[0097] Among them, for the waterproof cover group 15, in order to reduce wind resistance and improve structural strength, the upper cover body 151 is a hemispherical structure, and for the lower enclosure plate 152, it can be a cylindrical structure or a hemispherical structure.

[0098] In addition, an indicator light 17 is also provided on the upper cover body 151. The indicator light 17 can serve as an indicator when the hydroelectric power generation equipment floats in the sea at night, so as to improve the safety of use.

[0099] Furthermore, in order to facilitate the subsequent maintenance of each water wheel assembly, the rotating main shaft 21 includes a plurality of rotating sub-shafts 211, the plurality of rotating sub-shafts 211 are coaxially arranged, two adjacent rotating sub-shafts 211 are detachably connected together, and the rotating sub-shaft 211 at the top is detachably connected to the power input shaft 13; A water wheel assembly is disposed on each rotating sub-shaft 211 .

[0100] Specifically, each rotating sub-shaft 211 is provided with an independent water wheel assembly. During use, when a water wheel assembly is damaged and needs to be replaced and repaired, the rotating sub-shaft 211 corresponding to the damaged water wheel assembly can be disassembled separately, and the damaged water wheel assembly can be replaced separately, so as to improve the convenience of maintenance.

[0101] Embodiment 3: In another embodiment of the present application, a method for repairing a hydroelectric power generation equipment is provided, comprising: During replacement of the topmost water wheel assembly, firstly hang the connecting frame 22 of the water wheel assembly below the water wheel assembly to be disassembled and the floating platform 11 above, then disconnect the rotating sub-shaft 211 of the water wheel assembly to be disassembled from the power input shaft 13 and the rotating sub-shaft 211 of the water wheel assembly below to disassemble and remove the water wheel assembly to be disassembled; again place the new water wheel assembly between the floating platform 11 and the water wheel assembly below, and connect the rotating sub-shaft 211 on the new water wheel assembly between the power input shaft 13 and the rotating sub-shaft 211 of the water wheel assembly below.

[0102] Specifically, when the topmost driving module 2 needs to be disassembled and replaced, the connecting frame 22 of the driving module 2 below the driving module 2 to be disassembled needs to be suspended and connected with the upper floating platform 11 through a suspension device (such as an iron chain or a steel wire rope). The suspension device should have sufficient load-bearing capacity and stability to ensure that there is no structural deformation or instability during the suspension process. Through the connection of the suspension device, the stability of the driving module 2 below and the entire floating platform 11 can be ensured when the topmost driving module 2 is disassembled, and the structural instability caused by disassembly can be prevented.

[0103] By gradually disconnecting 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 lower drive module 2, the damaged drive module 2 can be taken out, and then a new drive module 2 is placed between the floating platform 11 and the lower drive module 2, and ensure that its rotating sub-shaft 211 is correctly connected to the power input shaft 13 and the rotating sub-shaft 211 of the lower drive module 2.

[0104] After completing the replacement, remove the suspension.

[0105] During replacement of the middle driving module 2, firstly, the connecting frame 22 of the driving module 2 below the driving module 2 to be disassembled is suspended and connected with the connecting frame 22 of the driving module 2 above, and then, the rotating sub-shaft 211 of the driving module 2 to be disassembled is disconnected from the rotating sub-shafts 211 of the upper and lower driving modules 2 to disassemble and remove the driving module 2 to be disassembled; again, a new driving module 2 is placed between the upper and lower driving modules 2, and the rotating sub-shaft 211 of the new driving module 2 is connected between the rotating sub-shafts 211 of the upper and lower driving modules 2.

[0106] Specifically, during the process of replacing the middle driving module 2, a suspension device is used to suspend and connect the connecting frame 22 of the driving module 2 below the driving module 2 to be removed with the connecting frame 22 of the upper driving module 2. This step ensures the stability of the upper and lower structures after the middle driving module 2 is removed, and prevents the structure from becoming unstable due to removal. Then, the connection between the rotating sub-shaft 211 of the driving module 2 to be removed and the rotating sub-shafts 211 of the upper and lower driving modules 2 is gradually disconnected, and then the driving module 22 to be removed is moved out from between the upper and lower driving modules 2. The operation should be performed slowly to ensure smooth movement.

[0107] After removing the middle drive module 2, the suspension device connects the two separated drive modules 2 together to prevent the lower drive module 2 from sinking into the water. Finally, the new drive module 2 is placed between the upper and lower drive modules 2, and its rotating sub-shaft 211 is ensured to be properly connected between the rotating sub-shafts 211 of the upper and lower drive modules 2.

[0108] After completing the replacement, remove the suspension.

[0109] During replacement of the bottom driving module 2, the rotating sub-shaft 211 of the driving module 2 to be disassembled is disconnected from the rotating sub-shaft 211 of the upper driving module 2 to remove the driving module 2 to be disassembled; a new driving module 2 is placed under the upper driving module 2 again, and the rotating sub-shaft 211 of the new driving module 2 is connected to the rotating sub-shaft 211 of the upper driving module 2.

[0110] Specifically, during the process of replacing the bottom driving module 2, a suspension device is used to suspend and connect the counterweight assembly 25 to the connecting frame 22 of the driving module 2 below the driving module 2 to be removed, and then the connection between the rotating sub-shaft 211 of the driving module 2 to be removed and the rotating sub-shaft 211 of the upper driving module 2 is gradually disconnected to ensure the safety of each step of the operation. After the driving module 2 to be removed is removed, a new driving module 2 is placed below the upper driving module 2, and it is ensured that its rotating sub-shaft 211 is correctly docked with the rotating sub-shaft 211 of the upper driving module 2. Finally, the counterweight assembly 25 is reconnected to the rotating sub-shaft 211 of the new driving module 2.

[0111] After completing the replacement, remove the suspension.

[0112] The above are only specific implementations 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 a person skilled in the art within the technical scope disclosed in the present application should be included in the protection scope of the present application. Therefore, the protection scope of the present application should be based on the protection scope of the claims.
