[0002] Waterfall power generation, as a form of hydropower generation, uses the natural drop of waterfalls and the principle of gravity to drive the generator to rotate through the impact of water flow on the blades, thereby generating electricity. Waterfall power generation technology has become relatively mature and has been widely used around the world. Especially in areas rich in hydropower resources, in recent years, with the continuous advancement of technology and policy support, the installed capacity and power generation of waterfall power generation have shown a steady growth trend.

[0003] However, the construction of waterfall power stations often requires the construction of dams or water diversion channels, which may change the natural flow of rivers and affect the living environment of aquatic organisms. The construction of waterfall power stations requires a large amount of capital, including land acquisition, engineering construction, equipment purchase, etc. Especially in areas with scattered water resources or complex terrain, the construction cost is higher, and the construction of waterfall power stations has high requirements for geographical location and terrain conditions. This results in the inability to fully utilize the gravity of waterfalls for power generation due to terrain restrictions, resulting in a waste of resources. Summary of the invention

[0004] The purpose of the present invention is to solve the problem that the construction of waterfall power stations in the prior art has high requirements on geographical location and terrain conditions, resulting in the inability to fully utilize the gravity of the waterfall for power generation due to terrain limitations, resulting in waste of resources, and to provide a waterfall power generation equipment and power generation method.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions:

[0006] A waterfall power generation device comprises a frame, wherein a plurality of propeller units are arranged inside the frame, and the output ends of the plurality of propeller units are all connected to the input end of a power generation unit;

[0007] The frame is placed under the waterfall. When the waterfall falls, the gravity generated by the waterfall drives the propeller unit to rotate, and the power is transmitted to the power generation unit to drive the power generation unit to generate electricity.

[0008] Furthermore, in the present invention, the propeller unit comprises a rotating shaft, the upper end of the rotating shaft is connected to the propeller, and the lower end of the rotating shaft is connected to the sprocket;

[0009] The sprocket is connected to the input end of the power generation unit.

[0010] Furthermore, in the present invention, in the plurality of propeller units, each sprocket is connected by a chain, and the chain is connected to the input end of the power generation unit.

[0011] Further, in the present invention, the power generation unit includes a generator, and the driving end of the generator is connected to the generator sprocket;

[0012] The generator sprocket is connected to the chain.

[0013] Furthermore, in the present invention, the rotating shaft and the propeller are fixedly connected by bolts.

[0014] Furthermore, in the present invention, a sealing ring is provided at the connection between the rotating shaft and the propeller.

[0016] Furthermore, in the present invention, an anti-wear coating is provided on the outer surface of the propeller.

[0017] Furthermore, in the present invention, the frame is made of alloy steel or composite material.

[0018] A method for generating electricity using a waterfall power generation device, comprising the following steps:

[0022] The power generation unit converts mechanical energy into electrical energy and transmits the electrical energy to the power grid or energy storage device.

[0023] Compared with the prior art, the present invention has the following beneficial effects:

The natural resources of the waterfall are used to generate electricity. A plurality of supporting legs are arranged at the bottom of the frame. The supporting legs include two inner and outer pipe sleeves, wherein the inner sleeve can move up and down along the outer sleeve. When the whole device is laid out, the height of different supporting legs can be adjusted according to different terrains, which is convenient for the stability of the placement of the whole device. It does not require a specific geographical location or complex terrain conditions to operate. Compared with projects such as dams or water diversion channels, the device has low requirements on geographical location and terrain conditions, and the device has a simple structure. , it can be flexibly arranged according to the actual width, height and flow of the waterfall. As long as there is a waterfall or a water flow with a certain drop, power generation can be achieved through the internal propeller unit, and the frame support has high stability and low requirements on terrain. This makes the equipment applicable to a variety of natural environments such as mountainous areas, rivers, and lakes. Compared with other hydroelectric power generation methods, the waterfall power generation equipment has lower requirements on terrain. During the power generation process, the water flow directly drives the propeller unit to rotate and then drives the power generation unit to generate electricity. There is no secondary regulation and control of the water flow through other transition structures. The entire conversion process is efficient and direct, which reduces energy loss and improves the utilization rate of water resources.

[0025] Furthermore, in the present invention, the propeller unit includes a rotating shaft, the upper end of the rotating shaft is connected to the propeller, and the lower end is connected to the sprocket; the sprocket is connected to the input end of the power generation unit, and the sprocket and chain are used as power transmission elements.

When maintenance or replacement of parts is required, the propeller unit can be operated separately without affecting the operation of the entire power generation equipment.

[0026] Furthermore, in the present invention, each sprocket is connected by a chain, and the chain is connected to the input end of the power generation unit. By connecting the sprockets of multiple propeller units through the chain, the power generated by multiple propellers can be concentratedly transmitted to the power generation unit, so that the power generation unit can receive a more stable and powerful power input, thereby improving the power generation efficiency and output power. The chain connection method helps to balance the load distribution and ensure the smoothness and reliability of the operation of the entire system.

[0027] Furthermore, in the present invention, the power generation unit includes a generator, the driving end of the generator is connected to the generator sprocket, and the generator sprocket is connected to the chain. The close fit between the generator sprocket and the chain reduces the loss of energy during the conversion process and improves the overall power generation efficiency. The connection method between the generator sprocket and the chain can withstand large loads and impacts to ensure stable operation even in harsh natural environments.

[0028] Furthermore, in the present invention, the rotating shaft and the propeller are fixedly connected by bolts, ensuring that the connection between the propeller and the rotating shaft will not loosen or fall off under high-speed rotation and water flow impact.

[0029] Furthermore, in the present invention, a sealing ring is provided at the connection between the rotating shaft and the propeller to prevent water from penetrating into the interior of the device from the connection between the rotating shaft and the propeller, thereby protecting the electrical components and mechanical parts inside the device from moisture erosion and extending the service life of the device.

[0030] Furthermore, in the present invention, the sprocket and the rotating shaft are connected by a flat key or a spline, ensuring that the connection between the sprocket and the rotating shaft will not loosen or fall off under high-speed rotation and water flow impact, thereby adapting to the complex working conditions in the waterfall power generation equipment.

[0031] Furthermore, in the present invention, an anti-wear coating is provided on the outer surface of the propeller to reduce the wear under the continuous impact of water flow, extend the service life of the propeller, and reduce the frequency of equipment replacement and maintenance.

The waterfall water flow resources in nature are utilized without consuming non-renewable resources such as fossil fuels, and the method is applicable to various types of waterfall environments. Whether it is a large waterfall or a small stream, effective power generation can be achieved by adjusting the scale and parameters of the equipment. The method has higher flexibility and does not require a specific geographical location or complex terrain conditions to operate. As long as there is a waterfall or a water flow with a certain drop, the device can be installed to generate electricity, thereby achieving a higher utilization rate of water resources.
