Description

Technical Field

[0001] This utility model relates to the field of hydropower generation, and in particular to a float-type hydropower generation device and power generation system. Background Technology

[0002] Hydropower generation utilizes the potential energy of water flowing from higher elevations, such as rivers and lakes, to lower elevations. This water power drives hydraulic machinery, converting the water's potential energy into mechanical energy. The output of this machinery is then connected to a generator, converting the mechanical energy into electrical energy. In a sense, hydropower generation is the process of converting water's potential energy into mechanical energy, and then into electrical energy. Most hydropower generation utilizes water turbines. However, driving these turbines requires a large water flow, necessitating the construction of reservoirs. This process is time-consuming and labor-intensive, sacrificing farmland, forests, villages, and towns, and requiring resettlement. It has a significant impact on the local ecological environment. Furthermore, in areas with low water flow and unsuitable for dam construction, hydropower resources cannot be effectively utilized for power generation. Therefore, designing a power generation device that does not require dam construction, has a simple structure, is easy to construct, and has low water flow requirements is particularly urgent.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] The purpose of this invention is to provide a float-type hydroelectric power generation device to solve the problems existing in the prior art, making the structure simple, easy to construct, and requiring less water flow.

[0032] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0033] This utility model provides a float-based hydroelectric power generation device, such as... Figures 1 to 4 As shown, it includes a float 1, a lifting assembly, a transmission assembly, and a guiding assembly;

[0034] The lifting component includes a vertically extending lifting pipe, with a float outlet 8 at the upper part of the lifting pipe, a float inlet 9 at the lower part, and a first door opening and closing component 10 at the float inlet 9.

[0035] The transmission assembly includes a ball frame 2, a bracket 3, a linear transmission component 4, and a transmission wheel 5. The transmission wheel 5 is mounted on the bracket 3, and its output end is connected to the generator. The linear transmission component 4 can be a chain or a transmission belt, etc., which is connected to the transmission wheel 5. One end of the linear transmission component 4 is connected to the ball frame 2, and the other end is connected to a counterweight mechanism. The weight of the counterweight mechanism is greater than the weight of the ball frame 2 but less than the sum of the weights of the ball frame 2 and the float 1. The ball frame 2 is used to receive the float 1 and reciprocates vertically between the float inlet 9 and the float outlet 8.

[0036] The guiding components include a guide-in-frame mechanism 12 and a guide-out-frame mechanism 13; the guide-in-frame mechanism 12 is located at the float outlet 8 and is used to discharge the float 1 from the lifting pipe into the ball frame 2; the guide-out-frame mechanism 13 is located on the ball frame 2 and is used to discharge the float 1 from the ball frame 2.

[0037] In use, float 1 is placed inside the lifting pipe, and the first switch assembly 10 is closed. Water is introduced into the lifting pipe and filled. Float 1 rises to float outlet 8 under buoyancy. At this time, the ball frame 2 has been pulled to float outlet 8 by the counterweight mechanism. The guide frame mechanism 12 discharges float 1 from float outlet 8, and ball frame 2 catches float 1. Under the weight of float 1 and ball frame 2, the linear transmission component 4 moves downward, causing the linear transmission component 4 to drive the transmission wheel 5 to rotate. The output end of the transmission wheel 5 drives the generator to generate electricity. When ball frame 2 reaches the float outlet 8... When the ball is at inlet 9, the first opening and closing assembly 10 is in the open state, and the water in the lifting pipe has been discharged. The guide frame mechanism 13 discharges the float 1 from the ball frame 2, so that the float 1 enters the lifting pipe from the float inlet 9. Then the first opening and closing assembly 10 is closed, and water is introduced back into the lifting pipe and filled. At the same time, the ball frame 2 is pulled up again to the float outlet 8 position by the counterweight mechanism, and enters the next power generation stage. This cycle repeats, realizing the generation of electricity using water power. It does not require water to be blocked and dams to be built, has a small water flow requirement, and has a simple structure, which is convenient for construction according to the terrain.

[0038] As an example of an implementable approach, such as Figure 1 As shown, the lifting pipe includes a lower ball chamber section 6 and an upper lifting section 7; the float inlet 9 is located on the side wall of the ball chamber section 6, and the float outlet 8 is located on the side wall of the lifting section 7; the top of the ball chamber section 6 has a ball chamber outlet communicating with the bottom of the lifting section 7, and the outlet is equipped with a second switch door assembly 11; when both the first switch door assembly 10 and the second switch door assembly 11 are closed, the ball chamber section 6 forms a closed space for accommodating the float 1. By setting the ball chamber section 6, when the float 1 enters the lifting pipe, it is only necessary to drain the water in the ball chamber section 6, so that the water in the lifting section 7 can be retained, greatly reducing water consumption, saving time in filling the lifting pipe, and improving power generation efficiency.

[0039] As an example of an implementable approach, such as Figures 1 to 2As shown, the guide frame mechanism 12 includes a lifting mechanism, a support plate 125, and a limiting member. The output end of the lifting mechanism is hinged to the support plate 125, which drives the support plate 125 to move up and down within the lifting pipe. The limiting member restricts the rotation angle of the support plate 125 around the hinge point, so that when there is no float 1, the support plate 125 remains tilted and the hinge end is higher than the free end. When the float 1 rises, the float 1 can push open the support plate 125 and reach the float outlet 8. The lifting mechanism can be a winch or a motor combined with transmission components. The attached figure shows an example of a lifting mechanism consisting of a lifting motor 121, a lifting rope 122, and a vertical plate 123. The demonstration shows that the limiting component can be a limiting rope 124 or a limiting block, etc. The limiting component shown in the attached figure is the limiting rope 124 as an example. One end of the support plate 125 is hinged to the lower part of the vertical plate 123. One end of the limiting rope 124 is fixed to the upper part of the vertical plate 123, and the other end is fixed to the free end of the support plate 125. In use, the float 1 floats up in the lifting part 7 and uses buoyancy to push open the hinged support plate 125 and reach the position of the float outlet 8. The lifting motor 121 drives the vertical plate 123 to move upward through the lifting rope 122, so that the support plate 125 supports the float 1 and moves it upward, and the float 1 rolls out of the float outlet 8 and falls into the ball frame 2.

[0040] As an example of an implementable approach, such as Figure 1 , Figure 3 , Figure 4 As shown, the guide frame mechanism 13 includes a movable plate 131; the movable plate 131 is located at the bottom of the ball frame 2, and its end near the lifting assembly is hinged to the ball frame 2; when the ball frame 2 is lifted off the ground, the free end of the movable plate 131 overlaps with the bottom of the ball frame 2 by its own weight, the hinge point is higher than the overlapping free end, and a support body 132 is provided at the bottom of this end; the height of the support body 132 is greater than the distance from the hinge point of the movable plate 131 to the bottom of the ball frame 2, and the bottom of the ball frame 2 has an opening for the support body 132 to pass through. When the ball frame 2 is located at the float outlet 8, because the free end of the movable plate 131 is lower, it forms... The inclined plane forms a slope. After the float 1 falls into the ball frame 2, it is limited and stabilized within the ball frame 2 by the action of the inclined plane. When the ball frame 2 descends to the float inlet 9, the bottom of the support body 132 contacts the ground, supporting the free end of the movable plate 131. The support height is higher than the hinge point, so that the movable plate 131 forms an inclined plane that slopes downward towards the lifting component, thereby causing the float 1 to roll into the ball chamber 6 along the inclined plane. The bottom of the ball chamber 6 slopes downward towards the side away from the transmission component, so that after the float 1 enters the ball chamber 6, it is limited and stabilized within the ball chamber 6 by the action of the inclined plane, thus improving the stability of the device.

[0041] As an implementable example, a first sensor is provided on the support 3 to detect the position of the ball frame 2. The first sensor is electrically connected to the first opening and closing door assembly 10 and the guide frame mechanism 12, so that when the first sensor detects that the ball frame 2 has descended, it sends an electrical signal to control the first opening and closing door assembly 10 to open and discharge the water in the ball chamber 6. A second sensor is provided in the ball chamber 6 to detect the position of the float 1 in the ball chamber 6. The second sensor is electrically connected to the first opening and closing door assembly 10 and the second opening and closing door assembly 11, so that when the second sensor detects that the ball frame 2 has descended, it sends an electrical signal to control the first opening and closing door assembly 10 to open and discharge the water in the ball chamber 6. When the float 1 is detected to be completely located in the ball chamber 6, it sends an electrical signal to control the first door opening assembly 10 to close, and then controls the second door opening assembly 11 to open. The lifting part 7 is equipped with a third sensor to detect the position of the float 1 in the lifting part 7. The third sensor is electrically connected to the guide frame mechanism 12. When the third sensor detects that the float 1 is located at the float outlet 8, and the first sensor detects that the ball frame 2 is also located at the float outlet 8, the first sensor and the third sensor send electrical signals to control the guide frame mechanism 12 to guide the float 1 into the ball frame 2.

[0042] As an example of implementation, the inner walls of the ball frame 2 and the inner walls of the ball chamber 6 are provided with buffer devices, which can be made of materials such as silicone or rubber. Under the action of the buffer devices, the float 1 is buffered when it enters the ball frame 2 or the ball chamber 6, thereby reducing the impact.

[0043] This utility model also provides a float-based hydroelectric power generation system, such as Figure 1 As shown, it includes two sets of float-type hydroelectric power generation devices, which are arranged symmetrically; the transmission components of the two sets of devices share the same linear transmission component 4, and the two ball frames 2 serve as counterweights for each other, thereby improving power generation efficiency.

[0044] Any adaptive changes made according to actual needs are within the protection scope of this utility model.
