Description

Technical Field

[0001] This application relates to the field of hydropower technology, and in particular to a hydropower generation device. Background Technology

[0002] Hydropower is widely used as a green power generation method, with ocean currents offering even greater potential for hydropower generation. Chinese Patent Publication No. CN118622565A discloses a suspended hydropower generation device and its maintenance method, which generates electricity via blades using a vertical axis. The drive module includes a support frame, a mounting plate, and multiple blades, with the blades mounted on the mounting plate, which in turn is mounted on the support frame. However, in actual use, the blades impact the rotating shaft during rotation. Furthermore, the hinged joints of the blades on the rotating shaft are prone to damage during rotational impacts, leading to reduced reliability. Additionally, the rotation angle of the blades is limited, and significant resistance is generated when moving against the water flow, affecting power generation efficiency. Moreover, the need for a support frame and mounting the blades on the mounting plate increases the overall weight and manufacturing cost. Therefore, this application aims to design a hydropower generation technology that improves reliability and power generation efficiency while reducing manufacturing costs. Summary of the Invention

[0014] In one embodiment, the mounting frame is further provided with a plurality of limiting components, which are arranged on the outer side of the corresponding baffle; the limiting components are configured to limit the rotation angle of the baffle when opening the through-hole.

[0015] In one embodiment, the water turbine drive module includes a plurality of water turbine components, each water turbine component including two mounting discs and blades disposed between the two mounting discs;

[0016] The multiple water turbine components are connected sequentially from top to bottom;

[0017] In two adjacent turbine assemblies, the mounting plate at the bottom of the upper turbine assembly is fixedly connected to the mounting plate at the top of the lower turbine assembly.

[0018] This application also provides a hydroelectric power generation device, including:

[0019] A power generation module, comprising a floating platform and a generator, wherein the generator is mounted on the floating platform and a power input shaft is mounted on the floating platform and the power input shaft is connected to the generator in a transmission manner;

[0020] A water turbine drive module, wherein the water turbine drive module adopts the hydropower generation equipment as described in any one of claims 1-7;

[0021] The power input shaft is fixedly connected to the topmost mounting plate of the water turbine drive module.

[0022] In one embodiment, a self-balancing component is also included;

[0023] The self-balancing assembly includes a first frame and a second frame. A first rotating shaft is disposed on the first frame, and a second rotating shaft is disposed on the second frame. The axis of the first rotating shaft and the axis of the second rotating shaft are perpendicular to each other. The second rotating shaft is rotatably disposed on the first frame. A first mounting port is disposed on the floating platform. The first frame is located in the first mounting port. The first rotating shaft is rotatably disposed on the floating platform.

[0029] By setting several through-holes on the mounting frame, and configuring baffles at the corresponding through-holes for opening and closing, during operation, the blades drive the mounting plate to rotate under the driving force of the water flow. During rotation, the baffles alternately occupy the front and back faces of the blades. When the baffle is on the front face, it closes the through-hole, allowing the water flow to apply pressure to the baffle and drive the mounting plate to rotate. When the baffle is on the back face, it opens the through-hole under the action of the water flow. Thus, during rotation, the driving force of the water flow on the blades in the same direction as the water flow is greater than that on the blades in the opposite direction, creating a larger pressure difference on both sides of the mounting plate, increasing the rotation speed and thus improving power generation efficiency. Furthermore, the mounting frame remains fixed to the mounting plate during rotation; only the baffles on different blades rotate due to the water flow, improving reliability. The overall structure is also simpler and easier to maintain, further enhancing operational reliability. Attached Figure Description

[0051] Example 1, as Figures 1-8 As shown, one embodiment of this application provides a hydroelectric power generation device, including:

[0052] The power generation module includes a generator 12.

[0053] Water turbine drive module 2, water turbine drive module 2 includes at least one water turbine assembly, the water turbine assembly includes:

[0054] Two mounting plates 24 are arranged vertically.

[0055] Multiple blades 23, each blade 23 including a mounting frame 231 and multiple baffles 232, the mounting frame 231 having multiple through-holes 233, the baffles 232 being hinged to the mounting frame 231 and arranged at corresponding through-holes 233; the baffles 232 are configured to close the through-holes 233 at the front surface of the blade 23, and the blades 23 are also configured to open the through-holes 233 at the back surface of the blade 23;

[0056] Multiple blades 23 are distributed around the axis of the mounting plate 24, the mounting frame 231 is arranged vertically, and the mounting frame 231 is fixedly disposed between two mounting plates 24.

[0057] Specifically, the water turbine drive module 2 adopts a shaftless design, with multiple blades 23 fixed between two mounting plates 24 arranged vertically. The mounting plates 24 are used to install and fix the multiple blades 23.

[0058] Multiple blades 23 are vertically arranged around the rotation axis of the mounting plate 24. Each blade 23 includes a mounting frame 231 and several baffles 232. The mounting frame 231 serves as the main support component and is fixedly installed between the two mounting plates 24. The mounting frame 231 has several through-holes 233 arranged in an array. Each through-hole 233 is equipped with a corresponding baffle 232. The baffles 232 are used to open and close the through-holes 233 so that the blades 23 at different positions generate different driving forces when driven by water flow.

[0059] The blade 23 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. It does not need to consider the streamline design of the blade. It only needs to arrange a corresponding number of through holes 233 to reduce the obstruction force generated by the blade 23.

[0060] The mounting plate 24 located at the top is connected to the generator drive via the power input shaft to drive the generator to generate electricity. During use, the water turbine drive module 2 is submerged in water, and the blades 23 rotate under the drive of the water flow to drive the power input shaft to rotate synchronously, thereby driving the generator to operate and generate electricity through the power input shaft.

[0061] Specifically, since the water flow assembly is vertically arranged in the water, during the rotation of the blade 23, the blade 23 will alternately generate pushing and blocking forces on the mounting plate 24. In order to increase the pushing force generated by the blade 23 and reduce the blocking force generated by the blade 23, the structure of the blade 23 has been improved. That is, the blade 23 includes a mounting frame 231 and a baffle 232 set on the mounting frame 231. The mounting frame 231 is provided with a through port 233 to meet the requirement of water flow through the mounting frame 231, and the baffle 232 opens and closes the through port 233 according to the change in the force generated by the blade 23 on the mounting plate 24.

[0062] Specifically, when the movement direction of the blade 23 is in the same direction as the water flow, the blade 23 will generate a pushing force on the mounting plate 24. At this time, the baffle 232 on the blade 23 will be located on the front side of the blade 23. Under the action of the water flow, the baffle 232 will cover the through-hole 233 on the mounting frame 231, so that the blade 23 can have a sufficiently large effective area to contact the water flow and generate thrust. In this way, the water flow will generate a maximum thrust on the blade 23 to drive the mounting plate 24 to rotate.

[0063] 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 mounting plate 24. At this time, the baffle 232 on the blade 23 will be located on the back flow surface of the blade 23. Under the action of the water flow, the baffle 232 will leave the through port 233 and thus open the through port 233 on the mounting frame 231, thereby reducing the effective area generated by the blade 23 and the water flow. In this way, the blocking force generated by the water flow on the blade 23 can be minimized.

[0064] By providing several through-holes 233 on the mounting frame 231, and configuring baffles 232 for opening and closing corresponding to the through-holes 233, during use, the blades 23 will drive the mounting plate 24 to rotate under the driving action of the water flow. During the rotation of the blades 23, the baffles 232 will alternately be located on the front and back surfaces of the blades 23. When the baffles 232 are located on the front surface of the blades 23, the baffles 232 will close the through-holes 233, thereby allowing the water flow to apply pressure to the baffles 232 to drive the mounting plate 24 to rotate. When the baffles 232 are located on the back surface of the blades 23, the baffles 232 will open the through-holes 233 under the action of the water flow. In this way, during the rotation, the water driving force on the blades 23 with the same direction of water flow is greater than the water driving force on the blades 23 with the opposite direction of water flow, so that a larger pressure difference can be formed on both sides of the mounting plate 24 to increase the rotation speed of the mounting plate 24 and improve the power generation efficiency.

[0065] In addition, since each blade 23 is installed using mounting plates 24 arranged vertically, there is no need to add an extra shaft to install the blade 23. This effectively reduces the overall weight of the water turbine drive module and reduces manufacturing costs. At the same time, the blade 23 is installed between the two mounting plates 24, making the overall structure more stable and reliable, and improving the reliability of use.

[0066] Furthermore, the mounting frame 231 of the blade 23 remains fixed to the mounting plate 24 during rotation, and only the baffles 232 on different blades 23 rotate due to the influence of water flow, which improves the reliability of use. In addition, the overall structure is simpler and easier to maintain, which also improves the reliability of use.

[0067] In one embodiment, the mounting plate 24 is provided with a positioning boss 241, and the mounting frame 231 abuts against the positioning boss 241.

[0068] Specifically, during the assembly of blades 23, two blades 23 will be fixed between two mounting plates 24, and the inner side of the mounting frame 231 of blades 23 will be abutted against the positioning boss 241 for positioning, thereby ensuring that blades 23 can be accurately installed in place.

[0069] For example, the mounting frame 231 can be fixed between the mounting plates 24 by welding or bolting. Then, during the process of fixing the mounting frame 231, the position of each blade 23 is positioned by the positioning boss 241, and then welding or bolting is performed.

[0070] Preferably, the circumferential surface of the positioning boss 241 is provided with a plurality of positioning notches, and the mounting frame 231 is engaged in the positioning notches.

[0071] Specifically, the circumferential surface of the positioning boss 241 is provided with multiple positioning notches evenly arranged. The positioning notches can position the mounting frame 231, thereby improving the installation accuracy of the mounting frame 231.

[0072] In one embodiment, the water turbine assembly further includes a clamp 25; the clamp 25 is wrapped around the outside of the plurality of mounting frames 231 and fixedly connected to the mounting frames 231.

[0073] Specifically, to further improve the connection reliability of the blades 23 installed between the mounting plates 24, the mounting frames 231 of multiple blades 23 are fastened together on the outside by clamps 25. The clamps 25 fix the mounting frames 231 of each blade 23 together, thereby effectively improving the overall structural connection strength.

[0074] As needed, the mounting frame 231 is provided with multiple clamps 25 from top to bottom.

[0075] Furthermore, during the process of the baffle 232 being impacted by the water flow to open the through-hole 233, in order to control the opening angle of the baffle 232, the mounting frame 231 is also provided with a plurality of limiting components (not shown), the limiting components are arranged on the outer side of the corresponding baffle 232; the limiting components are configured to restrict the rotation angle of the baffle 232 opening the through-hole 233.

[0076] Specifically, during the rotation of the blade 23, when the direction of movement of the blade 23 is opposite to the direction of water flow, the baffle 232 on the blade 23 will be opened by the water flow, and the water flow will pass through the through-hole 233 and flow through the mounting frame 231 of the blade 23. The baffle 232 is flipped open by the action of the water flow, and the flipping angle of the baffle 232 will be controlled by the limiting component.

[0077] The limiting component is a limiting rod, one end of which is fixedly mounted on the mounting frame 231, and the other end of which is arranged on the outside of the baffle 232.

[0078] Alternatively, the limiting component is a limiting plate, one end of which is fixedly mounted on the mounting frame 231, and the other end of which is arranged on the outside of the baffle 232.

[0079] In addition, to facilitate the installation of the baffle 232, the top of the baffle 232 is mounted on the mounting frame 231 via a hinge 234, or the side of the baffle 232 is mounted on the mounting frame 231 via a hinge 234.

[0080] Furthermore, in order to reduce the overall height of a single blade 23 and to fully utilize the water depth to improve power generation efficiency, the turbine drive module 2 is provided with multiple turbine assemblies, which are fixedly connected sequentially from top to bottom. In two adjacent turbine assemblies, the mounting plate at the bottom of the upper turbine assembly is fixedly connected to the mounting plate at the top of the lower turbine assembly.

[0081] Specifically, the water turbine drive module 2 can be configured with multiple water turbine components, which are stacked in the height direction to fully utilize the water depth for power generation. Adjacent water turbine components can be connected by bolts to their two mounting plates, thus assembling multiple water turbine components into a single structure.

[0082] 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 set on the floating platform 11.

[0083] Specifically, the suspended hydroelectric power generation device provided in this application uses a power generation module to generate electricity. The generator 12 on the power generation module is located on the floating platform 11 and is not immersed in water, which can effectively reduce the occurrence of damage to the generator 12 due to water ingress caused by seal failure, effectively improving the reliability of the generator 12 and thus improving the overall reliability of the suspended hydroelectric power generation device.

[0084] Example 2, as Figures 1-13 As shown, in order to improve the reliability of hydropower equipment and increase power generation efficiency, this application makes the following structural improvement design.

[0085] The power generation module provided in this application also includes a self-balancing component 16; the self-balancing component includes a first frame 161 and a second frame 162, a first rotating shaft is provided on the first frame 161, a second rotating shaft is provided on the second frame 162, 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 mounted 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 mounted on the floating platform 11, a power input shaft 13 is provided on the second frame 162, and the generator 12 is fixed on the second frame 162.

[0086] Specifically, the self-balancing assembly is configured with a first frame 161 and a second frame 162 that are capable of relative rotation, 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 mounted on the floating platform 11 via the first rotating shaft, the first frame 161 is able to rotate about the axis of the first rotating shaft in the first mounting port 110.

[0087] The generator 12 is mounted on the second frame 162 and connected to the power input shaft 13 on the second frame 162. The water turbine drive module 2 is connected to the lower end of the power input shaft 13 via the mounting plate 24. During normal power generation, the floating platform 11 floats on the water surface and sways due to the fluctuations in the water surface. During the swaying 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 water turbine drive module 2, so as to effectively utilize the water flow to generate electricity and improve the power generation efficiency. At the same time, the deflection force generated by the mounting plate 24 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.

[0088] It should be noted that the term "basically vertical" in this application refers to the vertical arrangement of the mounting plate 24 during the rotational power generation process. Those skilled in the art will understand that under the influence of water flow, the water turbine drive module 2 will inevitably tilt the mounting plate 24 at a certain angle. The aforementioned "basically vertical" means that the angle between the axis of the mounting plate 24 and the direction relative to its own weight is considered basically vertical within a set range. This angle range is designed to ensure that the water turbine drive module 2 can drive the mounting plate 24 to generate electricity normally and efficiently under the influence of water flow; for example, the angle can be 0-30 degrees. No specific limit is placed on the specific range of the angle.

[0089] In one embodiment, the first frame 161 and the second frame 162 are arranged laterally, with the first frame 161 surrounding the periphery of the second frame 162.

[0090] Specifically, the first frame 161 and the second frame 162 are arranged laterally to make full use of the space in the first mounting port 110 to install the self-balancing assembly 16. The first rotating shaft is mounted on the first bearing 115 set on the floating platform 11, and correspondingly, the second rotating shaft is mounted on the second bearing on the first frame 161.

[0091] In one embodiment, the second frame 162 is provided with a second mounting port 163, the second mounting port 163 is provided with a stepped mounting surface 164, the stepped mounting surface 164 is provided with a bottom ring 165, and the upper surface of the bottom ring 165 is provided with a first circular groove (not marked); the power input shaft 13 is provided with a shaft ring 131, and the lower surface of the shaft ring 131 is provided with a second circular groove; the self-balancing assembly 16 also includes a ring frame 166 and a plurality of support balls 167, the ring frame 166 is provided with a plurality of limiting through holes (not shown), and the support balls 167 are located in the limiting through holes; the 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 groove and the second circular groove.

[0092] Specifically, to improve the installation reliability of the power input shaft 13, a shaft ring 131 is also provided on the power input shaft 13. Furthermore, to ensure the power input shaft 13 can rotate smoothly on the second frame 162, a stepped surface 1513 is provided on the second frame 162 to mount the bottom ring 165. The shaft ring 131 is positioned above the bottom ring 165, and a support ball 167 is provided between them to support the rotation of the shaft ring 131.

[0093] In actual use, the power input shaft 13 can limit its installation position in the second mounting port 163 by the shaft ring 131, and the support ball 167 below the shaft ring 131 ensures smooth rotation under the drive of the water circuit module.

[0094] In order to ensure that the mounting plate 24 can rotate in a basically vertical position during use, and to quickly and automatically reset itself after the mounting plate 24 tilts due to excessive water flow impact, the following improvements are made to the hydroelectric power generation equipment.

[0095] A counterweight assembly 4 is provided at the lower end of the mounting plate 24 at the bottom. The counterweight assembly 4 is configured to apply a downward pulling force to the lower end of the mounting plate 24.

[0096] Specifically, the counterweight component 4 is arranged at the lower end of the mounting plate 24. The counterweight component 4 uses its own weight to keep the mounting plate 24 stable, so that the mounting plate 24 can be in a basically vertical state below the water surface or the tilt angle is within a set range (the set range of the tilt angle needs to be configured with a corresponding weight of counterweight component 4 according to the water flow velocity below the water surface, which is not limited here).

[0097] In one embodiment, the counterweight assembly 4 includes a connecting rod 41, a rotating seat 42, a first anchor chain (not shown), and a first counterweight component (not shown). The lower end of the connecting rod 41 is rotatably mounted on the rotating seat 42, and the first anchor chain is connected between the rotating seat 42 and the first counterweight component. The upper end of the connecting rod 41 is connected to the lower end of the rotating spindle.

[0098] Specifically, the counterweight assembly is fixedly installed on the mounting plate 24 at the bottom of the water turbine drive module 2 via a connecting rod 41. For example, the connecting rod 41 can be fixedly connected to the lower end of the mounting plate 24 via a coupling or flange.

[0099] The lower end of the connecting rod 41 is mounted on the rotating seat 42, and the connecting rod 41 is capable of rotating relative to the rotating seat 42.

[0100] During actual installation, after the counterweight assembly is in place, the rotating base 42 connects to the first counterweight component at the bottom via the first anchor chain, and the first counterweight component will fall to the seabed. The physical form of the first counterweight component can be an anchor, a counterweight block, or other structures, and there are no restrictions on this.

[0101] In actual use, the blade 23 is driven by the water flow to rotate the mounting plate 24. The mounting plate 24 will drive the bottom connecting rod 41 to rotate relative to the rotating seat 42. In this way, the first counterweight component connected to the rotating seat 42 will remain basically stationary.

[0102] By adding a counterweight assembly, a downward pulling force is applied to the rotating main shaft to ensure that the rotating main shaft can maintain a basically vertical state for stable power generation. At the same time, the first counterweight component is connected to the rotating base 42 through the first anchor chain, so that the rotating base 42 applies a downward pulling force to the connecting rod 41 connected to the rotating main shaft. In this way, as the rotating main shaft is driven to rotate by the blades, the connecting rod 41 can rotate with the rotating main shaft relative to the rotating base 42, while the first counterweight component connected to the rotating base 42 can sink to the seabed and remain stationary, playing a good counterweight role to stabilize the posture of the rotating main shaft. The rotating main shaft is not affected by the first counterweight component at the bottom during rotation, thereby increasing the rotation speed of the rotating shaft and improving the power generation efficiency of the hydroelectric power generation equipment.

[0103] In one embodiment, the rotating seat 42 is provided with a rotating mounting cavity (not marked), and the rotating seat 42 is also provided with a through hole 421;

[0104] The lower part of the connecting rod 41 is provided with a rotating support part 411, which has a ring structure and surrounds the outside of the connecting rod 41.

[0105] The rotating support 411 is rotatably disposed in the rotating mounting cavity, and the connecting rod 41 extends through the through hole 421 to the outside of the rotating seat 42.

[0106] Specifically, in order to meet the installation requirements that the connecting rod 41 can rotate relative to the rotating seat 42 without detaching from the rotating seat 42, a rotating mounting cavity can be provided in the rotating seat 42, and the rotating support part 411 provided at the lower part of the connecting rod 41 is located in the rotating mounting cavity to meet the installation requirements that it can rotate relative to the rotating seat 42 without detaching from the rotating seat 42.

[0107] Furthermore, the rotating mounting cavity is provided with two thrust ball bearings 43, which are arranged vertically, and the rotating support part 411 is located between the two thrust ball bearings 43.

[0108] Specifically, the two thrust ball bearings 43 provided in the rotating seat 42 are used to install the rotating support part 411 provided in the connecting rod 41. On the one hand, this allows the rotating support part 411 to be installed and limited by the two thrust ball bearings 43, and on the other hand, it also ensures that the rotating support part 411 can rotate smoothly on the thrust ball bearings 43.

[0109] Furthermore, the lower end of the connecting rod 41 is provided with a rotation limiting part 412, which has a circular structure and surrounds the outside of the connecting rod 41. The rotation limiting part 412 is located below the rotation support part 411.

[0110] The rotation limiting part 412 also abuts against the thrust ball bearing 43 located at the bottom.

[0111] Specifically, a rotation limiting part 412 may be provided at the bottom of the connecting rod 41. The rotation limiting part 412 will abut against the lower surface of the thrust ball bearing 43 at the bottom, so as to cooperate with the rotation support part 411 to axially limit the connecting rod 41 and provide circumferential rotation support.

[0112] In one embodiment, the rotating seat 42 includes an upper seat 422 and a lower seat 423, and the upper seat 422 is further provided with the through hole 421;

[0113] The upper seat 422 is disposed on the lower seat 423, and the rotating mounting cavity is formed between the upper seat 422 and the lower seat 423;

[0114] The first anchor chain is connected to the upper seat 422 or the lower seat 423.

[0115] Specifically, to facilitate the installation of the connecting rod 41, the rotating seat 42 adopts a split design. During the assembly process, the upper end of the connecting rod 41 is inserted into the through hole 421, and then the upper seat 422 and the lower seat 423 are fixedly connected.

[0116] The upper seat 422 and the lower seat 423 can be fixedly connected by bolts passing through the upper seat 422 and the lower seat 423 and then locked and fixed by locking nuts.

[0117] The lower surface of the upper seat 422 is provided with a first mounting groove, and the first mounting groove and the lower seat 423 form the rotating mounting cavity;

[0118] And / or, the upper surface of the lower seat 423 is provided with a second mounting groove, and the second mounting groove and the upper seat 422 form the rotating mounting cavity.

[0119] In another embodiment of this application, in order to accurately anchor the floating platform 11, it is necessary to keep the relative tilt positions of the multiple anchor chains 33 configured at the bottom of the floating platform 11 unchanged. 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 improvement is made to the seabed anchoring method of hydroelectric power generation equipment.

[0120] The bottom of the floating platform 11 is also provided with an anchoring module 3. The anchoring module 3 includes a deployment frame 31 and multiple counterweight components 32. Multiple anchor chains 33 are provided on the deployment frame 31, and the counterweight components 32 are provided on the deployment frame 31.

[0121] The upper end of the anchor chain 33 is connected to the floating platform 11. The anchor chain 33 is inclined between the floating platform 11 and the corresponding counterweight component 32. The anchor chain 33 is inclined from top to bottom towards the outside of the floating platform 11.

[0122] Specifically, during construction, the deployment frame 31 and counterweight components 32 are first deployed to the seabed together. Then, the anchor chain 33 is connected between the floating platform 11 and the deployment frame 31. Since the structure of the deployment frame 31 itself has precisely defined the positions of the different counterweight components 32, the bottom connection position of the anchor chain 33 can be determined and kept constant for different anchor chains 33. This ensures that the floating platform 11 at the top, to which the anchor chain 33 is connected, can be reliably pulled and positioned by the anchor chain 33. In this way, the relative positions between each anchor chain 33 can be precisely controlled, solving the problem of uncontrollable bottom anchor position on the seabed caused by deploying anchors separately, and improving the deployment position accuracy of the mooring module 3.

[0123] By setting a deployment frame 31 on the mooring module 3, multiple counterweight components 32 are installed and positioned via the deployment frame 31. The relative positions of the multiple counterweight components 32 are positioned by the deployment frame 31. In this way, after the mooring module 3 is deployed into the sea and sinks to the seabed, the relative positions of the multiple counterweight components 32 will not change. This ensures that the relative positions of the multiple anchor chains 33 connecting the counterweight components 32 and the floating platform 11 remain stable. During use, the multiple anchor chains 33 can provide multi-directional pulling force to the floating platform 11. Since the positions of the anchor chains 33 are precisely positioned by the deployment frame 31, each anchor chain 33 can effectively position the floating platform 11 at the top, allowing the floating platform 11 to float stably on the sea surface. This ensures that the floating platform 11 can maintain a stable floating state on the water surface, thereby improving the reliability of the floating platform 11.

[0124] Furthermore, the deployment frame 31 includes multiple telescopic beams 311, and each telescopic beam 311 is provided with a locking member 312. The locking member 312 is configured to lock the telescopic beam 311 after it has been extended or retracted into place; wherein, the multiple telescopic beams 311 are connected end to end in sequence.

[0125] Specifically, to further improve the versatility of the mooring module 3 and meet the deployment requirements of waters at different depths, the deployment frame 31 is a telescopic frame to allow for expansion and contraction of its dimensions. Specifically, during use, the lengths of the multiple telescopic beams 311 of the deployment frame 31 can be adjusted according to the depth of the water, thereby adjusting the relative positions of the various counterweight components 32 and ensuring that the tilt angles of the anchor chains 33 meet the requirements for stable floating of the top floating platform 11.

[0126] Furthermore, the telescopic beam 311 includes an outer tube 3111 and an inner core tube 3112. The outer tube 3111 is fitted over the inner core tube 3112. The outer tube 3111 and the inner core tube 3112 can slide relative to each other. The locking member 312 is disposed on the outer tube 3111 and configured to lock the position of the inner core tube 3112 relative to the outer tube 3111.

[0127] Specifically, for the telescopic beam 311, in order to meet the telescopic requirements, an outer sleeve 3111 is used in conjunction with an inner core tube 3112. The outer sleeve 3111 can move relative to the inner core tube 3112 to achieve adjustment of the length of the telescopic beam 311.

[0128] Meanwhile, after the length of the telescopic beam 311 is adjusted, the locking element 312 is used to further lock the relative position between the outer tube 3111 and the inner core tube 3112. In this way, during the deployment process after the deployment frame 31 is adjusted to the correct size, the locking element 312 prevents relative movement between the outer tube 3111 and the inner core tube 3112, thus preventing deformation of the deployment frame 31 during deployment and improving its reliability and convenience.

[0129] Furthermore, the outer tube 3111 is provided with multiple threaded holes (not shown), and the inner core tube 3112 is provided with multiple positioning holes (not shown). The multiple threaded holes extend along the length direction of the outer tube 3111, and the multiple 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 to the corresponding threaded hole and inserted into the corresponding positioning hole.

[0130] Specifically, the locking element 312 can be locked by using a locking bolt to lock the position between the outer tube 3111 and the inner tube 3112. That is, after adjusting the relative position of the outer tube 3111 and the inner tube 3112, the threaded hole will be aligned with the corresponding positioning hole. Then, tighten the locking bolt so that the locking bolt is inserted into the corresponding positioning hole. In this way, the position between the outer tube 3111 and the inner tube 3112 can be locked.

[0131] Furthermore, 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.

[0132] Specifically, the deployment frame 31 formed by the telescopic beams 311 can be an equilateral triangle or a rectangle, so that the ends of two adjacent telescopic beams 311 can be fixedly connected together by welding.

[0133] After the ends of the two telescopic beams 311 are welded together, a fixed connection is formed, and the counterweight component 32 can be connected to the corresponding fixed connection. For example, the counterweight component 32 can be connected to the fixed connection via a chain, or the counterweight component 32 can be welded to the fixed connection via a connecting beam.

[0134] Furthermore, the counterweight component 32 is a catapult basket, which is configured to hold the counterweight stones.

[0135] Specifically, the counterweight component 32 adopts 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 launched into the water. The stone-throwing basket is located below the launching frame 31. For example, the stone-throwing basket is suspended from the fixed connection part by a chain; or, the stone-throwing basket can be directly welded to the fixed connection part.

[0136] 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 mounting port 110, and the floating component 112 is disposed on the floating frame 111.

[0137] Specifically, the floating platform 11 needs to meet the installation requirements of the generator 12 at the top of the floating support and the water turbine drive module 2 at the bottom. Therefore, the floating platform 11 adopts a frame structure. That is, floating components 112 are set on the floating frame 111 to form the floating platform 11. The floating frame 111 serves as the main installation body, and the frame structure can improve the structural strength of the floating platform 11 itself; while the floating components 112 can be existing floating objects, such as floating boxes, floating blocks, etc., to increase the buoyancy required by the floating platform 11.

[0138] Furthermore, the floating frame 111 has a hollow structure, and a floating component 112 is installed in the hollow structure.

[0139] Specifically, to facilitate the installation and placement of the floating components 112, the floating frame 111 is designed as a hollow structure, allowing the floating components 112 to be housed within this hollow structure. This design allows for full utilization of the various positions on the floating frame 111 to arrange the floating components 112, thereby improving the overall buoyancy of the floating platform 11. Furthermore, if a floating component 112 in a specific location is damaged, the corresponding component within the hollow structure can be replaced individually, enhancing maintenance convenience.

[0140] In order to improve the flatness of the upper surface of the floating platform 11, a platform plate (not shown) can also be provided on the upper surface of the floating frame 111, which covers the hollow structure.

[0141] Specifically, the platform plate is laid on the upper surface of the floating frame 111 to cover the hollow structure, thus making the upper surface of the floating platform 11 flatter, which makes it easier for operators to carry out daily maintenance operations on the surface of the floating platform 11.

[0142] The platform plate can be a single piece (such as multiple iron plates welded together and fixed to the floating frame 111). Alternatively, the platform plate can be composed of multiple separately designed iron plates, each covering a corresponding openwork structure; and the iron plates can be connected to the floating frame 111 by hinges, so that when repairing the floating component 112 at the corresponding position, the iron plate at the corresponding position can be opened to facilitate the operator to repair or replace the floating component 112 on the floating platform 11.

[0143] Furthermore, multiple cable stakes 113 are provided on the floating frame 111, with the cable stakes 113 arranged close to the edge of the floating frame 111.

[0144] Specifically, the cable bollard 113 can be used to secure the cables on the maintenance vessel when it approaches the floating platform 11.

[0145] Furthermore, multiple cranes 114 are installed on the floating frame 111, with the cranes 114 arranged close to the edge of the floating frame 111.

[0146] Specifically, in order to facilitate the installation and maintenance of the underwater turbine drive module 2 on the floating platform 11, a crane 114 can be installed on the floating frame 111. The crane 114 can lift the corresponding parts into the water during the installation and maintenance process, or lift the parts that need to be replaced underwater out of the water.

[0147] To improve the waterproof protection capability of generator 12, improvements were made to the external waterproof structure of generator 12.

[0148] The floating platform 11 is also equipped with a waterproof cover assembly 15, which includes an upper cover 151 and a lower enclosure 152. The lower enclosure 152 has a ring structure and is set on the floating platform 11. The lower enclosure 152 surrounds the periphery of the generator 12. The upper cover 151 is set on the lower enclosure 152 and covers the top of the generator 12. The lower edge of the upper cover 151 forms an extension 1511. The extension 1511 extends downward and covers the outside of the connection formed between the upper cover 151 and the lower enclosure 152.

[0149] Specifically, a waterproof cover assembly 15 is also provided on the second frame 162 to shield and protect the generator 12 on the second frame 162. The lower enclosure 152 is fixedly installed on the second frame 162 around the generator 12 and the power input shaft 13, while the upper cover 151 is installed above the lower enclosure 152 to cover the generator 12.

[0150] Meanwhile, since the lower edge of the upper cover 151 is also provided with an extension 1511, the extension 1511 can effectively block the connection between the upper cover 151 and the lower enclosure 152. During use, even if waves hit the waterproof cover assembly 15, the extension 1511 can effectively prevent seawater from entering the waterproof cover assembly 15 through the connection between the upper cover 151 and the lower enclosure 152.

[0151] In this way, the generator 12 is covered by the waterproof cover assembly 15, which blocks sea waves during use and provides good waterproof protection for the generator 12.

[0152] Furthermore, a stepped surface 1513 is formed between the extension 1511 and the inner wall of the upper cover 151, and the stepped surface 1513 abuts against the upper edge of the lower cover 152.

[0153] Specifically, during installation, 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 overlaps the upper edge of the upper enclosure through the stepped surface 1513, thus allowing the upper cover to be installed on the upper enclosure.

[0154] To improve the reliability of the connection between the upper cover 151 and the lower enclosure 152, after the upper cover 151 and the lower enclosure 152 are joined together via the stepped surface 1513, further connection and fixation are required between them. Therefore, the upper cover 151 is provided with a first connecting part 1512, and the lower enclosure 152 is provided with a second connecting part 1521, with the first connecting part 1512 and the second connecting part 1521 connected together.

[0155] Specifically, after the upper cover 151 is hoisted onto the lower enclosure 152, it is connected and engaged by the first connecting part 1512 and the second connecting part 1521, thereby making the upper cover 151 and the lower enclosure 152 firmly connected together to improve the connection reliability during use.

[0156] The physical representation of the first connecting part 1512 and the second connecting part 1521 can adopt various structural forms. For example, the first connecting part 1512 is a plurality of connecting posts provided on the lower edge of the upper cover 151, and the lower end of the connecting post is provided with an end head, the outer circumferential dimension of the end head being larger than the outer circumferential dimension of the connecting post; the second connecting part 1521 is a strip-shaped hole formed on the lower cover plate 152, the opening size of the strip-shaped hole decreasing along the length direction; the connecting post is inserted into the strip-shaped hole, and the end head is arranged below the strip-shaped hole and configured to prevent the connecting post from disengaging from the strip-shaped hole.

[0157] Specifically, a connecting post is provided at the lower part of the upper cover 151, and correspondingly, a slotted hole is provided at the upper part of the lower enclosure 152. During assembly, after the upper cover 151 is hoisted above the lower enclosure 152, the connecting post is aligned with the corresponding slotted hole. Then, the connecting post is inserted into the slotted hole, and the upper cover 151 is rotated at a certain angle so that the end of the connecting post moves to the smaller end of the slotted hole to prevent the connecting post from disengaging from the slotted hole. In this way, the upper cover 151 can be installed on the lower enclosure 152.

[0158] Alternatively, the first connecting part 1512 is a support beam provided on the upper cover 151. The support beam has an arc structure and the two ends of the support beam form insertion interfaces. The second connecting part 1521 is an insertion protrusion provided on the lower cover 152. The insertion protrusion is inserted into the corresponding insertion interface.

[0159] Specifically, during assembly, after the upper cover 151 is hoisted above the lower enclosure 152, the insertion protrusion is aligned with the insertion interface. Then, the stepped surface 1513 of the upper cover 151 abuts against the lower enclosure 152, allowing the insertion protrusion to be inserted into the insertion interface, thereby installing the upper cover 151 onto the lower enclosure 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 enclosure 152.

[0160] In order to reduce wind resistance and improve structural strength, the upper cover 151 of the waterproof cover assembly 15 is a hemispherical structure, while the lower cover 152 can be either a cylindrical structure or a hemispherical structure.

[0161] In addition, an indicator light 17 is also provided on the upper cover 151. The indicator light 17 can serve as an indicator when the hydroelectric power generation equipment is floating in the sea at night, so as to improve the safety of use.

[0162] Furthermore, in order to facilitate individual maintenance of each water turbine component in the later stage, the mounting plate 24 includes multiple rotating sub-shafts 211, which are arranged coaxially. Two adjacent rotating sub-shafts 211 are detachably connected together, and the topmost rotating sub-shaft 211 is detachably connected to the power input shaft 13.

[0163] Each rotating sub-shaft 211 is equipped with a water turbine assembly.

[0164] Specifically, each rotating sub-shaft 211 is equipped with an independent water turbine assembly. During use, when a water turbine assembly is damaged and needs to be replaced or repaired, the rotating sub-shaft 211 corresponding to the damaged water turbine assembly can be disassembled separately, and the damaged water turbine assembly can be replaced individually, thereby improving the convenience of maintenance.

[0165] In another embodiment of this application, a method for overhauling a hydroelectric power generation device is also provided, comprising:

[0166] During the replacement of the topmost water turbine assembly, firstly, the connecting frame 22 of the water turbine assembly below the water turbine assembly to be disassembled is suspended and connected to the upper floating platform 11. Then, the rotating sub-shaft 211 of the water turbine assembly to be disassembled is disconnected from the power input shaft 13 and the rotating sub-shaft 211 of the lower water turbine assembly to remove the water turbine assembly. Next, the new water turbine assembly is placed between the floating platform 11 and the lower water turbine assembly, and the rotating sub-shaft 211 on the new water turbine assembly is connected between the power input shaft 13 and the rotating sub-shaft 211 of the lower water turbine assembly.

[0167] Specifically, when the topmost water turbine drive module 2 needs to be disassembled and replaced, a suspension device (such as a chain or wire rope) is used to suspend the connecting frame 22 of the water turbine drive module 2 below it to the upper floating platform 11. The suspension device should have sufficient load-bearing capacity and stability to ensure that no structural deformation or instability occurs during the suspension process. The suspension connection ensures the stability of the water turbine drive module 2 below and the entire floating platform 11 when the topmost water turbine drive module 2 is disassembled, preventing structural instability caused by disassembly.

[0168] By gradually disconnecting the rotating sub-shaft 211 of the water turbine drive module 2 to be disassembled from the power input shaft 13 and the rotating sub-shaft 211 of the lower water turbine drive module 2, the damaged water turbine drive module 2 can be removed. Then, the new water turbine drive module 2 is placed between the floating platform 11 and the lower water turbine drive module 2, ensuring that its rotating sub-shaft 211 is correctly aligned with the power input shaft 13 and the rotating sub-shaft 211 of the lower water turbine drive module 2.

[0169] After the replacement is completed, the suspension device is removed.

[0170] During the replacement of the middle water turbine drive module 2, firstly, the connecting frame 22 of the water turbine drive module 2 below the water turbine drive module 2 to be disassembled is suspended and connected to the connecting frame 22 of the water turbine drive module 2 above. Then, the rotating sub-shaft 211 of the water turbine drive module 2 to be disassembled is disconnected from the rotating sub-shafts 211 of the upper and lower water turbine drive modules 2 to remove the water turbine drive module 2. Then, the new water turbine drive module 2 is placed between the upper and lower water turbine drive modules 2, and the rotating sub-shaft 211 of the new water turbine drive module 2 is connected between the rotating sub-shafts 211 of the upper and lower water turbine drive modules 2.

[0171] Specifically, during the replacement of the middle water turbine drive module 2, a suspension device is used to suspend the connecting frame 22 of the water turbine drive module 2 below it from the connecting frame 22 of the water turbine drive module 2 above it. This step ensures the stability of the upper and lower structures after the middle water turbine drive module 2 is removed, preventing structural instability caused by disassembly. Then, the connection between the rotating sub-shaft 211 of the water turbine drive module 2 to be removed and the rotating sub-shafts 211 of the upper and lower water turbine drive modules 2 is gradually disconnected. The water turbine drive module 22 to be removed is then moved out between the upper and lower water turbine drive modules 2. The operation should be carried out slowly to ensure smooth movement.

[0172] After removing the middle water turbine drive module 2, the suspension device connects the two spaced water turbine drive modules 2 together to prevent the lower water turbine drive module 2 from sinking underwater. Finally, the new water turbine drive module 2 is placed between the upper and lower water turbine drive modules 2, ensuring that its rotating sub-shaft 211 is correctly aligned between the rotating sub-shafts 211 of the upper and lower water turbine drive modules 2.

[0173] After the replacement is completed, the suspension device is removed.

[0174] During the replacement of the bottom water turbine drive module 2, the rotating sub-shaft 211 of the water turbine drive module 2 to be disassembled is disconnected from the rotating sub-shaft 211 of the upper water turbine drive module 2 to remove the water turbine drive module 2; the new water turbine drive module 2 is then placed below the upper water turbine drive module 2, and the rotating sub-shaft 211 of the new water turbine drive module 2 is connected to the rotating sub-shaft 211 of the upper water turbine drive module 2.

[0175] Specifically, during the replacement of the bottom water turbine drive module 2, a suspension device is used to suspend the counterweight assembly 4 to the connecting frame 22 of the water turbine drive module 2 below the module to be disassembled. Then, the connection between the rotating sub-shaft 211 of the water turbine drive module 2 to be disassembled and the rotating sub-shaft 211 of the upper water turbine drive module 2 is gradually disconnected, ensuring the safety of each step. After removing the water turbine drive module 2 to be disassembled, the new water turbine drive module 2 is placed below the upper water turbine drive module 2, ensuring that its rotating sub-shaft 211 is correctly aligned with the rotating sub-shaft 211 of the upper water turbine drive module 2. Finally, the counterweight assembly 4 is reconnected to the rotating sub-shaft 211 of the new water turbine drive module 2.

[0176] After the replacement is completed, the suspension device is removed.

[0177] The above are merely specific embodiments of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
