[0027] like Figure 1-Figure 4 As shown, an embodiment of the present application provides a suspended hydroelectric power generation device, comprising:

[0028] A suspended power generation module 1, the suspended power generation module 1 includes a suspended platform 11 and a generator 12, a power input shaft 13 is provided on the suspended platform 11, the generator 12 is fixed on the suspended platform 11, and the motor shaft of the generator 12 is transmission-connected to the power input shaft 13; the motor shaft of the generator 12 is transmission-connected to the power input shaft 13 through a gearbox 14.

[0029] The driving module 2 includes a supporting frame 21, a rotating main shaft 22 and a plurality of blades 23. The rotating main shaft 22 is vertically arranged and rotatably disposed on the supporting frame 21. The plurality of blades 23 are vertically arranged and rotatably disposed on the rotating main shaft 22. The rotating main shaft 22 is also provided with a plurality of limit stops 24, and the limit stops 24 are arranged between two adjacent blades 23.

[0030] The rotating main shaft 22 is connected to the power input shaft 13 .

[0031] Specifically, the suspended hydroelectric power generation device provided in the present application can solve at least the following two technical problems. The first technical problem is that the motor is immersed in water and has high sealing requirements, resulting in high cost and poor reliability. The second technical problem is that the blades 23 are frequently subjected to the reciprocating force of the water flow, and the blades 23 are easily damaged if they only rely on the support of the hinged parts.

[0032] To solve the above two technical problems, the suspended hydroelectric power generation device in the present application adopts a suspended power generation module 1 to install the generator 12 on the suspended platform 11 instead of immersing it in water; and to solve the above two technical problems, the suspended hydroelectric power generation device in the present application adopts a method of adding a limit stopper 24 to the rotating main shaft 22 in the driving module 2 to assist in supporting the blades 23. The suspended power generation module 1 and the driving module 2 are described below in conjunction with the accompanying drawings.

[0033] For the suspended power generation module 1, the suspended platform 11 can float on the water surface, thereby satisfying that the generator 12 can be installed on the suspended platform 11 without being immersed in water. In this way, the requirements for sealing the generator 12 can be effectively reduced to reduce the manufacturing cost; and the generator 12 is arranged on the suspended platform 11, and when the seal fails, the generator 12 will not be immersed in water, thereby effectively improving the safety and reliability of the generator 12.

[0034] In addition, for the suspended power generation module 1, a power input shaft 13 is provided on the suspended platform 11, and a driving force is introduced through the power input shaft 13 to drive the generator 12 to rotate so as to realize power generation by utilizing water flow.

[0035] By setting up the floating platform 11, the floating platform 11 has sufficient buoyancy to float on the water surface, so that the generator 12 can float on the water surface. In this way, the sealing requirements for the generator 12 can be effectively reduced, which greatly reduces the manufacturing cost of the generator 12 required for comprehensive water sealing treatment due to its location under the water surface. At the same time, since the generator 12 is not immersed in water, it can effectively reduce the occurrence of damage to the generator 12 due to water ingress due to sealing failure, thereby effectively improving the reliability of the generator 12 and improving the overall reliability of the suspended hydroelectric power generation device.

[0036] As for the driving module 2, the rotating main shaft 22 is rotatably mounted on the supporting frame 21, and a plurality of blades 23 are distributed around the axis of the rotating main shaft 22. During use, the blades 23 are driven by water flow to drive the rotating main shaft 22 to rotate. Moreover, when the blades 23 follow the rotating main shaft 22 to rotate, the driving force of the water flow on the blades 23 is different at different positions.

[0037] When the blade 23 is driven by water flow to drive the rotating main shaft 22 to rotate, the limit stop 24 can support the blade 23, so that when the blade 23 is under force, the blade 23 is auxiliary supported by the limit stop 24, which can reduce the force on the hinged part of the blade 23 and improve the reliability of use.

[0038] When the blades 23 are driven by water flow to block the normal rotation of the rotating main shaft 22 , the limit stopper 24 can also support the blades 23 , thereby further improving the reliability of the blades 23 .

[0039] By arranging a limit stop 24 on the rotating main shaft 22, the blade 23 is located between the two limit stops 24 and can rotate on the rotating main shaft 22. In this way, in actual use, since the blades 23 are distributed around the rotating main shaft 22, the blades 23 at different positions are subjected to different forces during the flow of water. For the blade 23 to which the water flows to generate a driving force for the rotating main shaft 22, the blade 23 will abut against the limit stop 24 on the corresponding side to support the blade 23 by using the limit stop; in addition, for the blade 23 to which the water flows to generate a driving force for the rotating main shaft 22, the blade 23 can also be supported by the corresponding side, thereby achieving that the blade 23 can be provided with additional support force by the limit stop 24 during the rotation process, and also reducing the force on the hinged part of the blade 23, thereby reducing the damage caused by the frequent repeated force on the hinged part of the blade 23, thereby improving the reliability of the use of the blade 23 to improve the overall reliability of the use of the suspended hydropower generation device.

[0040] A space for limiting the rotation angle of the blade 23 is formed between two adjacent limit stoppers 24 .

[0041] In one embodiment, one side wall of the blade 23 forms a driving surface 231 , and the other side wall of the blade 23 forms a first guide surface 232 . The driving surface 231 is an arc-shaped concave surface, and the first guide surface 232 is an arc-shaped convex surface.

[0042] Specifically, the blade 23 is designed to have a driving surface 231 with an arc-shaped concave surface formed on one side wall, and a first guide surface 232 with an arc-shaped convex surface formed on the other side wall. When water flows through the driving surface 231, due to the pressure difference generated by the concave surface design, the blade 23 can more efficiently capture the energy of the water flow and drive the rotating main shaft 22 to rotate. At the same time, the convex surface design of the first guide surface 232 helps to reduce the resistance of the water flow, so that the water flow can flow through the blade 23 more smoothly, thereby improving the energy conversion efficiency of the entire device.

[0043] The concave-convex surface design of the blade 23 can more effectively utilize the water flow energy and improve the power generation efficiency. In addition, this design can also reduce the water flow resistance on the surface of the blade 23, so that the blade 23 can rotate more smoothly and extend the service life of the device. At the same time, the concave-convex surface design can be optimized according to different water flow conditions and has stronger adaptability.

[0044] In another embodiment, one end of the limit stopper 24 is fixedly mounted on the rotating main shaft 22, and the other end of the limit stopper 24 is suspended.

[0045] Specifically, one end of the limit stopper 24 is fixed to the rotating main shaft 22, and the other end is suspended. The purpose of this design is to limit the maximum rotation angle of the blade 23 through the flexibility of the suspended end without affecting the normal rotation of the blade 23, to ensure that the blade 23 does not rotate excessively under high water flow speed, thereby protecting the rotating main shaft 22 and the blade 23. The limit stopper 24 can effectively protect the blade 23 and the rotating main shaft 22, and avoid mechanical damage caused by excessive rotation of the blade 23.

[0046] Furthermore, one side wall of the limit stopper 24 forms a support surface 241, and the outer contour of the support surface 241 matches the first guide surface 232 of the blade 23; the other side plate of the limit stopper 24 forms a second guide surface 242, and the second guide surface 242 is an arc-shaped convex surface.

[0047] Specifically, the limit stopper 24 is designed to have a support surface 241 formed on one side wall to match the guide surface of the blade 23, and a second guide surface 242 formed on the other side wall to form an arc-shaped convex surface. The support surface 241 matches the first guide surface 232 of the blade 23. When the blade 23 is driven by the water flow to drive the rotating main shaft 22 to rotate, the first guide surface 232 of the blade 23 can be in good contact with the support surface 241 of the limit stopper 24, so as to provide stable support through the support surface 241 to prevent the blade 23 from being offset or deformed during the rotation process. The design of the second guide surface 242 helps to further optimize the flow path of the water flow, reduce the water flow resistance, and improve the overall efficiency of the device.

[0048] The design of the limit stopper 24 can improve the stability and durability of the blade 23 and extend the service life of the device. At the same time, the design of the second guide surface 242 can further reduce the water flow resistance and improve the energy conversion efficiency.

[0049] Furthermore, a waterproof cabin 15 is provided on the suspension platform 11 , the generator 12 is located in the waterproof cabin 15 , and the power input shaft 13 extends into the waterproof cabin 15 and is drivingly connected to the motor shaft of the generator 12 .

[0050] Specifically, a waterproof cabin 15 is designed on the floating platform 11, and the generator 12 is installed in the waterproof cabin 15. The design of the waterproof cabin 15 ensures the waterproof performance of the generator 12 in the aquatic environment and protects it from water erosion. The upper end of the power input shaft 13 extends into the waterproof cabin 15, and the power input shaft 13 is connected to the motor shaft of the generator 12 through a reduction gearbox. The setting of the waterproof cabin 15 provides additional protection, so that the generator 12 can operate stably for a long time in the aquatic environment, avoiding equipment damage and failure caused by water infiltration.

[0051] In another embodiment of the present application, for the support frame 21 in the driving module 2, the support frame 21 includes an upper frame 211, a lower frame 212 and a plurality of columns 213, the columns 213 are arranged between the upper frame 211 and the lower frame 212, bearings are respectively arranged on the upper frame 211 and the lower frame 212, and the rotating main shaft 22 is arranged on two of the bearings.

[0052] Specifically, the upper frame 211 and the lower frame 212 are connected by the column 213 to form a stable structure. The upper frame 211 and the lower frame 212 are respectively provided with bearings, and the rotating main shaft 22 is installed by the upper and lower bearings, so that the rotating main shaft 22 can rotate freely, ensuring that the rotating main shaft 22 can rotate smoothly and efficiently under the push of the water flow.

[0053] The support frame 21 can provide stable support to ensure the smooth operation of the rotating main shaft 22 under the action of water flow. By arranging bearings on the upper frame 211 and the lower frame 212, the friction of the rotating main shaft 22 is reduced, and the operating efficiency and life of the device are improved. At the same time, the design of the column 213 increases the stability of the structure, so that the entire device can operate reliably in a harsh underwater environment.

[0054] In another embodiment of the present application, Figure 5 As shown, in order to improve the power generation efficiency and fully utilize the underwater space, the suspended hydroelectric power generation device includes a plurality of the driving modules 2;

[0055] In two adjacent driving modules 2, the two rotating main shafts 22 are connected together, and the two supporting frames 21 are connected together;

[0056] The rotating main shaft 22 of the driving module 2 at the top is drivingly connected to the motor shaft of the generator 12 .

[0057] Specifically, the floating hydroelectric power generation device includes a plurality of drive modules 2, and two adjacent drive modules 2 are connected together through a rotating main shaft 22 and a supporting frame 21 to form a multi-stage drive system. The rotating main shaft 22 of the drive module 2 at the top is drivingly connected to the motor shaft of the generator 12, and through the linkage of the plurality of drive modules 2, more efficient energy conversion is achieved.

[0058] The series connection of multiple drive modules 2 can improve the power generation efficiency and stability of the entire device. The multi-stage drive system can more effectively utilize water flow energy and improve energy conversion efficiency. In addition, this modular design facilitates the maintenance and replacement of a single drive module 2, thereby improving the maintainability and service life of the device.

[0059] Furthermore, an anti-rotation connecting rod 25 is provided between two adjacent support frames 21 .

[0060] Specifically, an anti-rotation link 25 is provided between two adjacent support frames 21. The anti-rotation link 25 is designed to limit the relative rotation between the two support frames 21, ensure the stability of the entire device under the action of water flow, and prevent the rotating main shaft 22 and the blade 23 system from being offset or rotating out of control due to the impact of water flow. The provision of the anti-rotation link 25 can improve the stability of the device, reduce the relative rotation between different drive modules 2 that affects the power generation efficiency, and improve the durability of the overall structure.

[0061] In order to facilitate the rapid connection of two adjacent support frames 21 underwater to prevent relative rotation, pin holes can be respectively provided on the upper frame 211 and the lower frame 212 of the support frame 21, and the upper end of the anti-rotation link 25 can be provided with a plug whose size is larger than the pin hole, and the lower end of the anti-rotation link 25 is provided with a thread. The anti-rotation link 25 is inserted into the pin hole of the adjacent support frame 21 and a locking nut is threadedly connected at the bottom, so that the upper and lower support frames 21 are connected together through the anti-rotation link 25. In addition, the anti-rotation link 25 can also further carry the function of the lower drive module 2.

[0062] Furthermore, the support frame 21 of the driving module 2 at the bottom is also provided with a detachable anchor chain 26 , and a counterweight is connected to the bottom of the anchor chain 26 .

[0063] Specifically, a detachable anchor chain 26 is installed on the support frame 21 of the driving module 2 at the bottom, and a counterweight is connected to the bottom of the anchor chain 26. The anchor chain 26 and the counterweight are designed to provide additional fixing and stabilization to ensure that the device will not drift or move significantly with the water flow in an environment with strong water flow. The weight of the counterweight increases the stability of the device, allowing it to maintain balance and fixed position in the water.

[0064] The installation method of the anchor chain 26 and the support frame 21 of the driving module 2 at the bottom can adopt the installation method of the conventional anchor chain 26. For example, after the anchor chain 26 passes through the pin hole, the upper end link of the anchor chain 26 is pulled downward and fixed with the link of the anchor chain 26 located below the support frame 21 by tying with steel wire ropes, etc., and there is no restriction on the installation method of the anchor chain 26 and the support frame 21.

[0065] By setting the anchor chain 26 and the counterweight, the device can be effectively prevented from drifting in the water flow environment, ensuring that the device always remains in the predetermined position and operates stably. The detachable design of the anchor chain 26 facilitates installation and maintenance, and improves the operational flexibility and ease of use of the device. In addition, the counterweight increases the stability of the system and reduces the risk of failure caused by device displacement.

[0066] Furthermore, for a plurality of driving modules 2 , in order to conveniently connect the rotating main shafts 22 in two adjacent driving modules 2 together, a coupling component 221 is provided at the end of the rotating main shaft 22 extending outside the supporting frame 21 .

[0067] Specifically, in actual use, after the two driving modules 2 are connected in series, the two rotating main shafts 22 arranged up and down are connected through their respective coupling components 221 , thereby realizing power transmission through each rotating main shaft 22 .

[0068] The coupling component 221 is a flange. Specifically, the flange is designed to fix the rotating main shaft 22 to other equipment through bolts or nuts to ensure a stable mechanical connection. By connecting the two flanges, the two rotating main shafts 22 can be fixedly connected together. The flange design provides a reliable mechanical connection method to ensure the stability and reliability between the rotating main shaft 22 and other equipment.

[0069] Alternatively, the coupling component 221 is a metal claw disk, and the metal chuck is provided with a plurality of raised teeth. Specifically, the coupling component 221 can be a metal claw disk. The metal claw disk is engaged with other devices through a plurality of raised teeth, so as to achieve fast and convenient installation and removal. The metal claw disk design achieves quick connection through the teeth, simplifies the installation and maintenance process, and improves the convenience of operation.

[0070] At the same time, both connection methods can be selected according to specific needs, providing a flexible connection solution.

[0071] In one embodiment, when multiple driving modules 2 are used, the support frame 21 of the driving module 2 at the top is directly installed on the upper suspension platform 11. The specific installation method can be a detachable installation method such as bolt fixing.

[0072] Furthermore, the suspended platform 11 is also provided with an air compressor 16, multiple air intake control valves (not shown), multiple exhaust control valves (not shown) and multiple ventilation pipes (not shown), each of the ventilation pipes is provided with a three-way connection, and the ventilation pipes are respectively connected to the corresponding air intake control valve and the corresponding exhaust control valve through the three-way connection, and the air outlet of the air compressor 16 is respectively connected to each of the air intake control valves; the column 213 is provided with an air charging and discharging port (not marked) and a water inlet and outlet (not marked), and the air charging and discharging port is connected to the corresponding ventilation pipe.

[0073] Specifically, the suspension platform 11 is equipped with an air compressor 16, an air intake control valve, an exhaust control valve and a vent pipe. The air compressor 16 injects air into the hollow structure of the column 213 through the air intake control valve and the vent pipe to discharge the water inside the column 213 and increase the buoyancy of the column 213. Similarly, the exhaust control valve is used to control the release of air and adjust the water level inside the column 213. In this way, the buoyancy of each support frame 21 itself can be adjusted to meet different requirements during installation, disassembly and use.

[0074] Among them, the air charging and discharging ports arranged on the column 213 are connected to the air intake control valve and the exhaust control valve respectively through the ventilation pipe, so as to realize the inlet and outlet regulation of air and water, and can flexibly adjust the buoyancy and balance of the device to improve its stability and adaptability in the water flow environment.

[0075] As for the vent pipe itself, it has a strong external structural strength to meet the requirements of underwater use. Of course, in actual use, the number of series-connected drive modules 2 cannot be increased arbitrarily. The number is determined by considering the water depth environment and the buoyancy of the suspended platform 11, so that the length of the vent pipe is not arbitrary. For example, taking the height dimension of a single drive module 2 as 3 meters as an example, after 3 drive modules 2 are connected in series at the bottom, the length of the vent pipe required to be configured is about 10 meters, which can meet the requirements of underwater pressure resistance and inflation and deflation.

[0076] Furthermore, in order to facilitate disassembly at a later stage, hooks arranged up and down may be provided on the column 213 , wherein the hook located at the upper side is a hanging hook 214 , and the hook located at the lower side is a load-bearing hook 215 .

[0077] Specifically, the hook added to the column 213 can meet the requirement of facilitating the disassembly and assembly operations of the operators during the later disassembly and maintenance, thereby effectively reducing the difficulty of the operations during installation and maintenance.

[0078] Specifically, when the driving module 2 at a position other than the bottom is damaged and needs to be disassembled and replaced, in order to prevent the driving module 2 below from sinking to the bottom of the water during disassembly, the suspension hook 214 on the column 213 can be temporarily connected to the upper suspension platform 11 or the driving module 2 above that is not disassembled. In this way, the driving module 2 that needs to be disassembled in the middle can be conveniently taken out, and the new driving module 2 can be installed in place with greater convenience.

[0079] In another embodiment of the present application, a method for repairing a suspended hydroelectric power generation device is provided, comprising:

[0080] During replacement of the topmost drive module 2, the support frame 21 of the drive module 2 below the drive module 2 to be disassembled is first suspended and connected to the suspended platform 11 above, and then the rotating main shaft 22 of the drive module 2 to be disassembled is disconnected from the power input shaft 13 and the rotating main shaft 22 of the drive module 2 below to disassemble and remove the drive module 2 to be disassembled; the new drive module 2 is placed again between the suspended platform 11 and the support frame 21 of the drive module 2 below, and the rotating shaft of the new drive module 2 is connected between the power input shaft 13 and the rotating main shaft 22 of the drive module 2 below.

[0081] Specifically, when the topmost driving module 2 needs to be disassembled and replaced, the support frame 21 of the driving module 2 below the driving module 2 to be disassembled needs to be suspended and connected with the upper suspension 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 will be 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 suspension platform 11 can be ensured when the topmost driving module 2 is disassembled, preventing structural instability caused by disassembly.

[0082] By gradually disconnecting the connection between the rotating main shaft 22 of the drive module 2 to be disassembled and the power input shaft 13 and the rotating main shaft 22 of the lower drive module 2, the damaged drive module 2 can be taken out, and then, the new drive module 2 is placed between the suspension platform 11 and the supporting frame 21 of the lower drive module 2, and ensure that its rotating shaft is correctly connected to the power input shaft 13 and the rotating main shaft 22 of the lower drive module 2.

[0083] After completing the replacement, remove the suspension.

[0084] During replacement of the middle drive module 2, firstly, the support frame 21 of the drive module 2 below the drive module 2 to be disassembled is suspended and connected with the support frame 21 of the drive module 2 above, and then, the rotating main shaft 22 of the drive module 2 to be disassembled is disconnected from the rotating main shafts 22 of the upper and lower drive modules 2 to disassemble and remove the drive module 2 to be disassembled; and again, a new drive module 2 is placed between the support frames 21 of the upper and lower drive modules 2, and the rotating shaft of the new drive module 2 is connected between the rotating main shafts 22 of the upper and lower drive modules 2.

[0085] Specifically, during the process of replacing the middle drive module 2, a suspension device is used to suspend and connect the support frame 21 of the drive module 2 below the drive module 2 to be removed with the support frame 21 of the upper drive module 2. This step ensures the stability of the upper and lower structures after the middle drive module 2 is removed, and prevents the structure from becoming unstable due to removal. Then, the connection between the rotating spindle 22 of the drive module 2 to be removed and the rotating spindles 22 of the upper and lower drive modules 2 is gradually disconnected, and then the drive module 2 to be removed is moved out from between the support frames 21 of the upper and lower drive modules 2. The operation should be performed slowly to ensure smooth movement.

[0086] 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 support frames 21 of the upper and lower drive modules 2, and its rotation axis is ensured to be properly connected to the rotation main axis 22 of the upper and lower drive modules 2.

[0087] After completing the replacement, remove the suspension.

[0088] During replacement of the bottom drive module 2, the rotating spindle 22 of the drive module 2 to be disassembled is disconnected from the rotating spindle 22 of the upper drive module 2 to remove the drive module 2 to be disassembled; the new drive module 2 is placed under the support frame 21 of the upper drive module 2 again, and the rotating shaft of the new drive module 2 is connected to the rotating spindle 22 of the upper drive module 2.

[0089] Specifically, during the process of replacing the bottom driving module 2, the anchor chain 26 is suspended and connected to the support frame 21 of the driving module 2 below the driving module 2 to be removed by using a suspension device, and then the connection between the rotating main shaft 22 of the driving module 2 to be removed and the rotating main shaft 22 of the upper driving module 2 is gradually disconnected to ensure the safety of each step of the operation. The driving module 2 to be removed is removed from under the support frame 21 of the upper driving module 2, and then a new driving module 2 is placed under the support frame 21 of the upper driving module 2, and its rotating shaft is ensured to be correctly connected to the rotating main shaft 22 of the upper driving module 2. Finally, the anchor chain 26 is reconnected to the support frame 21 of the new driving module 2.

[0090] After completing the replacement, remove the suspension.

[0091] Preferably, during the process of replacing the driving module 2 , the requirement of convenient disassembly and assembly can be achieved by adjusting the buoyancy of each column 213 .

[0092] Specifically, during use, since the driving module 2 needs to be immersed in water, the buoyancy generated by the column 213 in the driving module 2 is smaller than the gravity of the driving module 2 itself, so that the driving module 2 can be ensured to be stable in the water. When replacement and maintenance are required, before disassembly and assembly of the driving module 2 to be replaced, gas is first filled into the column 213 in the driving module 2 to be disassembled through the air compressor 16 to increase the buoyancy of the driving module 2 itself, thereby making the buoyancy of the driving module 2 substantially the same as the gravity of the driving module 2 itself.

[0093] In this way, after disconnecting the support frame 21 and the rotating main shaft 22 of the driving module 2, the operator can easily move the driving module 2 out underwater, and then, in the process of lifting the driving module 2, the column 213 can be further inflated through the air compressor 16 to make the buoyancy of the driving module 2 greater than its own gravity, thereby achieving automatic floating to the water surface to improve maintenance convenience.

[0094] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited to this. Any changes or substitutions that can be easily thought of by technicians familiar with the technical field within the technical scope disclosed by the utility model should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
