DETAILED DESCRIPTION

[0020] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described in combination with the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0021] The following is combined with Figure 1-4 The present invention will be further described:

[0022] A multi-stage water wheel water lifting gravity power generation device includes a bracket 1 and a lower water tank 2. The upper part of the bracket 1 is provided with multiple water lifting devices 4 from top to bottom. A starting water pipe 3 is provided above the topmost water lifting device 4. In this embodiment, the starting water pipe 3 is first used to release water to drive the multiple water lifting devices 4 to rotate in sequence. The rotation of the water lifting device 4 will lift the water in the lower water tank 2 to the top of the bracket 1 to replace the starting water pipe 3 to release water, so as to realize the self-circulation of water lifting. The starting water pipe 3 can use tap water or a starting water tank can be provided above the bracket 1.

[0023] The water lifting device 4 includes a water lifting wheel 41, a speed increasing water pump 43 and a water lifting drive device. The water lifting wheel 41 is rotatably set on the bracket 1 through the water lifting wheel shaft 42. The speed increasing water pump 43 is set on the top of the bracket 1. The water lifting drive device is set between the rotating shaft of the speed increasing water pump 43 and the water lifting wheel shaft 42. The water lifting drive device includes a driving sprocket 45 and a passive sprocket 46. The driving sprocket 45 and the passive sprocket 46 are fixedly connected to the water lifting wheel shaft 42 and the rotating shaft of the speed increasing water pump 43 respectively. A chain 47 is set between the driving sprocket 45 and the passive sprocket 46.

[0024] A water inlet 44 and a water delivery port 49 are provided on the speed increasing water pump 43. The water inlet 44 is connected to the lower water tank 2 through an upper water pipe 48. A guide plate 5 fixedly connected to the bracket 1 is provided between the water delivery port 49 and the topmost water lifting wheel 41. A guide plate 5 fixedly connected to the bracket 1 is provided between multiple water lifting wheels 41.

[0025] In this embodiment, the water pipe 3 is started to release water into the guide plate 5 between the water delivery port 49 and the top water-lifting water wheel 41. After the water is guided by the guide plate 5, the position of the water flow can be ensured to be more accurate, and the utilization rate of the water flow by the water-lifting water wheel 41 is higher. The water flow impacts the water-lifting water wheel 41 to rotate the water-lifting water wheel 41, and drives the rotating shaft of the speed-increasing water pump 43 to rotate through the active sprocket 45, the chain 47, and the passive sprocket 46, and lifts the water to the guide plate 5 between the water delivery port 49 and the top water-lifting water wheel 41 through the upper water pipe 48, so as to realize the lifting of water from a low place to a high place. Setting up multiple water-lifting devices 4 can lift water at the same time, thereby increasing the efficiency and rate of water lifting. In this embodiment, two water-lifting devices 4 are provided. After the water flow impacts the upper water-lifting water wheel 41, it continues to impact the lower water-lifting water wheel 41 after being guided by the guide plate 5 between the two water-lifting water wheels 41. The two water-lifting devices 4 lift water at the same time, thereby increasing the efficiency and rate of water lifting.

[0026] A gravity power generation device 6 is arranged at the lower part of the bracket 1, and the gravity power generation device 6 includes a power generation water wheel 61. The center of the power generation water wheel 61 is rotatably arranged on the bracket 1 through a power generation water wheel shaft 62. A generator 67 matched with the power generation water wheel shaft 62 is arranged on the outside of the bracket 1. A plurality of gravity water tanks 63 are arranged on the power generation water wheel 61. An openable and closable tank cover 65 is arranged on the gravity water tank 63. The tank cover 65 is rotatably arranged on the outer side of the gravity water tank 63 through a tank cover rotating shaft 64. A tension spring 66 for driving the tank cover 65 to open is arranged on the tank cover rotating shaft 64.

[0027] A bin cover device for driving the bin cover 65 to close is provided on one side of the power generation water wheel 61, and the bin cover device is fixedly connected to the bracket 1. The bin cover device includes an arc guide plate 68, which is provided on one side of the power generation water wheel 61, and the arc guide plate 68 is fixedly connected to the bracket 1. A roller 69 that cooperates with the arc guide plate 68 is rotatably provided on the outer side of the bin cover 65.

[0028] A guide plate 5 fixedly connected to the bracket 1 is provided between the lowermost water-lifting water wheel 41 and the power-generating water wheel 61 .

[0029] In this embodiment, the water flow after impacting the water-lifting water wheel 41 is guided by the guide plate 5 between the lowest water-lifting water wheel 41 and the power-generating water wheel 61, and then impacts the power-generating water wheel 61. The water flow is gathered into the partial gravity water tank 63 with an opening upward. Due to the fact that there is water in the partial gravity water tank 63 and no water in the other part of the gravity water tank 63, a gravity difference is generated on both sides of the entire water-lifting water wheel 41, which drives the water-lifting water wheel 41 to rotate, and drives the generator 67 to rotate through the power-generating water wheel shaft 62 to generate electricity.

[0030] However, when the gravity water tank 63 with an upward opening and filled with water rotates to a certain angle, the water in the gravity water tank 63 will leak out, resulting in a decrease in the water in the gravity water tank 63, reducing its own gravity, causing the gravity difference on both sides of the entire water-lifting water wheel 41 to be too small, reducing the rotation speed of the water-lifting water wheel 41, and affecting the efficiency of the generator 67. In this embodiment, a tank cover 65 is rotatably provided on the gravity water tank 63 through a tank cover rotating shaft 64, and a tension spring 66 is provided on the tank cover rotating shaft 64 to drive the tank cover 65 to open. In a normal state, the tension spring 66 controls the tank cover 65 to be in an open state. When the bin cover 65 rotates until the roller 69 on the outside contacts the arc guide plate 68, the arc guide plate 68 squeezes the roller 69, so that the bin cover 65 is closed, reducing the leakage in the gravity water bin 63, ensuring the gravity of the gravity water bin 63 filled with water, ensuring a large gravity difference between the two sides of the entire power generation water wheel 61, increasing the speed of the power generation water wheel 61, and increasing the efficiency of the generator 67. When the bin cover 65 rotates to the lower part of the entire power generation water wheel 61, the roller 69 on the outside separates from the arc guide plate 68, and the bin cover 65 is opened under the action of the tension spring 66, and the water in the gravity water bin 63 quickly leaks into the lower water tank 2. In this embodiment, a plurality of gravity water tanks 63 are provided on the power generation water wheel 61, an openable tank cover 65 is provided on the gravity water tank 63, a tension spring 66 is used to drive the tank cover 65 to open, and a roller 69 and an arc-shaped guide plate 68 are provided to close the tank cover 65. The structure can also be provided on the water-lifting water wheel 41. By creating a larger gravity difference on both sides of the water-lifting water wheel 41, the rotation speed of the water-lifting water wheel 41 is increased, thereby improving the water-lifting effect.

[0031] A water inlet pipe 7 connected to the lower water tank 2 is arranged in the lower water tank 2 , a one-way valve 8 is arranged on the water inlet pipe 7 , and an overflow port 9 is arranged at the upper part of the lower water tank 2 .

[0032] In this embodiment, when the water level in the lower water tank 2 is lower than the one-way valve 8, the one-way valve 8 automatically opens, and the water inlet pipe 7 replenishes water to the lower water tank 2. When the multi-stage water wheel water lifting gravity power generation device of the present application stops working, the water in the water lifting device 4 and the gravity power generation device 6 is collected in the lower water tank 2, the water volume in the lower water tank 2 increases, and the water is discharged from the overflow port 9.

[0033] In summary, the present invention is not limited to the above specific embodiments. Those skilled in the art may make several changes and modifications without departing from the spirit and scope of the present invention. The scope of protection of the present invention shall be subject to the claims of the present invention.
