Abstract
Description
Technical Field
[0001] This utility model relates to the field of hydropower technology, specifically a floating horizontal hydropower generation device. Background Technology
[0002] Hydropower is a widely used clean energy technology and occupies a mainstream position in the power generation field. Hydropower primarily utilizes the driving force of water flow on a turbine in a hydroelectric generator to convert water energy into mechanical energy, and then from mechanical energy into electrical energy. It has very strict requirements on water flow velocity; a certain flow rate and volume are necessary for effective power generation. However, not most water resources are usable. To build large-scale hydroelectric power stations, it is necessary to divert water from the upper reaches of major rivers to create enormous hydroelectric potential energy and a significant drop in elevation. This results in high costs and long construction periods for hydropower, requiring substantial investment and mobilizing enormous human, material, and financial resources, even though only a limited amount of water resources can be utilized. Because it is heavily dependent on natural resources and climate and seasons, the development of hydropower has been hampered.
[0003] To address the aforementioned issues, we propose a floating, advection hydroelectric power generation device. This device can generate electricity in most river basins (natural water flows with a velocity exceeding 2.5 meters per second), and is simple to construct. It is both environmentally friendly and highly efficient, with extremely low power generation costs, achieving maximum power generation efficiency with minimal manpower, material resources, and financial resources. Utility Model Content
[0004] To address the problems in the background technology, this utility model provides a floating horizontal hydroelectric power generation device.
[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:
[0006] A floating horizontal hydroelectric power generation device includes a floating body and a counter-rotor generator. The counter-rotor generator is fixedly installed at the middle of the bottom end of the floating body. The counter-rotor generator includes an outer rotor and an inner rotor shaft. An inner rotor turbine is fixedly installed at the middle of the left end of the inner rotor shaft, and an outer rotor turbine is installed at the middle of the left end of the outer rotor.
[0007] The inner rotor turbine is located at the middle of the left end of the outer rotor turbine and rotates in the opposite direction to the outer rotor turbine.
[0008] Preferably, an anchoring pile is provided at the middle of the left end of the floating body, and the floating body and the anchoring pile are connected by a chain.
[0009] Preferably, a support frame is provided at the middle of both ends of the opposing dual rotor generator, and the two sets of support frames are respectively fixedly installed on both sides of the bottom end of the floating body.
[0010] Preferably, the ratio of the diameter of the inner rotor turbine to the diameter of the outer rotor turbine is 1:2.
[0011] Preferably, a fixing ring is provided at the middle of the left end of the floating body, and the chain is connected to the floating body through the fixing ring.
[0012] Preferably, a light is installed on the top of the floating body.
[0013] Compared with the prior art, the beneficial effects of this utility model are:
[0014] In this design, the anchor piles and floating bodies allow the opposing dual-rotor generator to float on the water surface. Driven by the water flow, the inner and outer rotor turbines rotate, causing the outer and inner rotors of the opposing dual-rotor generator to rotate in opposite directions. This generates motion that cuts magnetic lines of force, converting mechanical energy into electrical energy, thus achieving hydroelectric power generation. Furthermore, during operation, when the water flow velocity reaches 2.5 meters per second or higher, the opposing dual-rotor generator can stably generate qualified electrical energy. This floating, horizontal hydroelectric power generation device, installed on the water surface, is simpler, more practical, easier to implement and construct than traditional hydroelectric power generation technology. It also promotes the effective utilization and development of resources, enabling hydroelectric power generation in the middle and lower reaches of some rivers, thus enhancing its widespread applicability.

[0018] The technical solution in this application embodiment is to solve the problems mentioned in the background art, and the overall idea is as follows:
[0019] Example: Refer to Figure 1 - Figure 2As shown, a floating horizontal hydroelectric power generation device of this embodiment includes a floating body 1 and a counter-rotor generator 2. The counter-rotor generator 2 is fixedly installed at the bottom middle of the floating body 1. The counter-rotor generator 2 includes an outer rotor 21 and an inner rotor shaft 22. An inner rotor turbine 221 is fixedly installed at the left middle of the inner rotor shaft 22, and an outer rotor turbine 211 is installed at the left middle of the outer rotor 21.
[0020] The inner rotor turbine 221 is located at the middle of the left end of the outer rotor turbine 211. The two are in the same direction and rotate in the opposite direction to the outer rotor turbine 211, which can generate cutting magnetic lines of force, thereby converting mechanical energy into electrical energy. The electrical energy is then transmitted to electrical appliances for distribution and use through current output wires. It can also be connected to energy storage devices to store electrical energy or connected to the grid to be transmitted to users.
[0021] An anchor pile 4 is provided at the middle of the left end of the floating body 1. The floating body 1 and the anchor pile 4 are connected by a chain 5. The main function of the anchor pile 4 is to limit the position of the floating body 1.
[0022] In some examples, support frames 3 are provided at the middle of both ends of the opposing dual rotor generator 2. The two sets of support frames 3 are fixedly installed on both sides of the bottom end of the floating body 1. The support frames 3 play a role in stabilizing the support. The support frames 3 are movably connected to the generator inner rotor shaft 22, so that the generator inner rotor shaft 22 can rotate under the drive of the inner rotor turbine 221.
[0023] In some examples, the diameter ratio of the inner rotor turbine 221 to the outer rotor turbine 211 is 1:2 to avoid the inner rotor turbine 221 being too large, which would affect the water flow force on the outer rotor turbine 211, so that the water flow from upstream can drive both the inner rotor turbine 221 and the outer rotor turbine 211 to rotate simultaneously.
[0024] In some examples, a fixing ring 6 is provided at the middle of the left end of the floating body 1, and the chain 5 is connected to the floating body 1 through the fixing ring 6, so as to limit the position of the floating body 1.
[0025] In some examples, a light 7 is installed on the top of the floating body 1, mainly for illumination at night.
[0026] In some examples, the anchor piles 4 and the floating body 1 are arranged so that the opposing dual rotor generator 2 can swing with the water flow and change with the water level, so that the working efficiency of the opposing dual rotor generator 2 is not affected. In addition, the amount of water mass (such as silt) will not affect the working efficiency of the opposing dual rotor generator 2. In fact, the increased density of water will increase the efficiency of hydropower generation and improve the stability during use.
[0027] The working principle of this utility model is as follows:
[0028] During use, the floating body 1 needs to be placed on the river channel, and the floating body 1 is fixed by the anchor pile 4 and the chain 5 so that the floating body 1 can float stably on the water surface and avoid being swept away by the water flow. At this time, under the action of the upstream water flow, the inner rotor turbine 221 and the outer rotor turbine 211 will rotate, thereby driving the outer rotor 21 of the opposing dual rotor generator 2 and the inner rotor of the generator to rotate in opposite directions, thereby generating a motion that cuts magnetic lines of force, thus converting mechanical energy into electrical energy and realizing the hydroelectric power generation.
[0029] This utility model's power generation device can stably generate qualified electrical energy when the water flow velocity reaches 2.5 meters per second or higher. Compared with traditional hydroelectric power generation technology, which requires a water flow velocity of 5 meters per second or higher (some large-scale hydroelectric power generation requires a flow velocity of 10 meters per second or higher), this utility model achieves a more efficient effect.
[0030] Furthermore, this floating, advection hydroelectric power generation device is installed on the water surface, unaffected by water fluctuations, water level, water quality, climate, temperature, and other natural conditions. It is simpler, more practical, easier to implement and construct than existing technologies, and allows for more effective resource utilization and development. This makes hydroelectric power generation feasible in the middle and lower reaches of some rivers, enhancing its widespread applicability.
[0031] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
