Other features are the same as in the second embodiment.

The following is a hydroelectric power generation system using the present invention.

Choose a pond with an area of more than 50 square kilometers and a water depth of more than 3 meters. Dig a 30-meter-deep pit on one side of the pond, gradually narrowing from top to bottom, and the bottom is 10 meters wide. An arc-shaped fixed high wall 4 is built, and the wall is provided to the inner side of the pond. The fixed high wall 4 is divided into upper and lower walls. The upper wall has a height of 12 meters, a length of 600 to 800 meters, and a thickness of 1 The meter is set at 2 meters below the bottom of the pond. The depth of the lower wall is 36 meters and the width gradually becomes 10 meters. A funnel-shaped reservoir is built on the top of the fixed high wall 4. The funnel is 12 meters away from the water level of the pond. The reservoir has a volume of 800 to 1000 cubic meters.

Each buoyancy bucket has a height of 3 meters, an inner diameter of 1.6 meters, and a volume of 6 cubic meters. The height of each lifting bucket is 0. 7 meters, the diameter is 1.48 meters, the weight is 50 kilograms, and its volume is 1. 2033 cubic meters, equal to 1. 2033 tons of water, which is upgraded to superior buoyancy bucket and lifting bucket. The hoisting device provided 1.2033 tons of water. The volume of each cylindrical float is

1. 813,664 cubic meters, the float is hollow, the weight is 50 kg, the height is 1 m, the inner diameter of the buoyancy barrel is greater than the float diameter of 0.08 m, so the float diameter is 1.52 m, and 20 water drops are placed around the float 3. The hole 3-1, the diameter of each of the water holes 3_1 is 80 mm, the volume of the 20 water holes is 0. 08 cubic meters, so the actual volume of the float after the drop hole is slightly larger than 1. 37 cubic meters; The volume of the 8 m buoyancy bucket is 1. 6 cubic meters minus the float 1. 37 cubic meters equals 0. 23 cubic meters, 0. 23 cubic meters plus the falling water hole 0. 08 cubic meters is 0. 31 cubic meters, the 0. 31吨水。 The 31 cubic meters is the volume of the water channel formed by the buoyancy barrel 1 and the float 3, the 0.31 cubic meters is equal to 0.31 tons of water. The volume of the float is 0. 8 m3, and the volume of the float is 0. 8 m3. The volume of the drift of 0. 8 m is 1.45 m3.

Buoyancy formula: F float = G row = P liquid gV row

When the object floats, F float = G object, because the float and the lift bucket have the same weight, the float is larger than the lift bucket, and the F float formed in the water is larger than the G object, and the conclusion is as follows, to make the lift bucket 2 1. When 2033 tons of water is lifted by 1 meter, the height of buoyancy water in buoyancy bucket 1 is greater than 2 meters.

When the Hutang Water 10 is filled into the lifting bucket 2, 1. 2033 tons of water is injected into the buoyancy bucket 1 as a portion of the water, and 4. 4132 tons of water, 4.8142 tons of water in the buoyancy bucket 1 0. 31 into the buoyancy bucket 1 and float 3 of the water channel, 1 m of the float 3 of which 0. 8 meters is close to all draft, the buoyancy bucket 1 meter deep volume is 2. 0096 cubic meters, that is, half a meter can be loaded 1 Tons of water. In the 4.132 tons of water injected into the buoyancy bucket, 0. 317 tons of water have been occupied, and the remaining 4, 5032 tons of water are combined under the bottom of the float, and the float 3 and the 1.2333 tons of water in the lifting bucket 2 are combined. The entire large floating object has floated up. At this time, the bottom of the floating float 3 is located at the bottom of the buoyancy bucket 1: 4. 4032*0. 5=2. 2516 meters, meeting the requirement that the water in the lifting bucket 2 is raised by 1 meter, 2. The 1 meter high of 2516 meters plus float 3 is 3.2516 meters, which meets the requirements for water injection from the upper lifting bucket. Buoyancy water The horizontal line is slightly above 2 meters, that is, 2.2516 meters. When the second stage is to perform the lifting function, its buoyancy water rises flat line is also 2.252 meters, so the first level lifting bucket 2-1 When the bottom is at 3.2516 meters, it is level with the horizontal line of the buoyancy bucket 1-2 of the second stage, which ensures that the fifth bucket of water delivered by the first stage lifting bucket 2-1 to the second stage buoyancy bucket 1-2 is completely released. In order to meet the requirements of injecting water into the upper lifting bucket, so that 1 part of water is injected into the lifting bucket 2, and 4 parts of water can be injected into the buoyancy bucket 1 to meet the requirements of the superior lifting. Therefore, it is concluded that each water lifting point can carry out the lifting action after receiving five parts of water, that is, 4 parts of buoyancy water to raise a lifting water. After the lifting, the buoyancy water should be retreated to the lower level, as "five liters and one retreat four". When the buoyant water is discharged to the negative level, 4 parts of water is left in each buoyancy bucket, and five water is required for one water lifting point of the negative level, and five buoyancy barrels are required to supply water to the four water lifting points of the negative level, so it can be used as "five Four changes to four five".

Install 50 buoyancy buckets 1 and lifting buckets 2 on the fixed high wall, also called 50 lifting points. The water of the first-stage buoyancy bucket 1-1 and the first-stage lifting bucket 2-1 is specially made by the lake pond water 10 Provided; the top of the first-stage lifting bucket 2-1 is at a water line of 1 meter deep in the lake pond, and the second-stage buoyancy bucket 1-2 is 1 meter higher than the first-stage buoyancy bucket 1-1, third and fourth ... The 12th grade is 1 meter high in height, and adopts the method of "five liters and one retreat four" to form a 50-string water lifting device, and the water ladder is sent to the height required for power generation. The lower part of the first stage is a negative level, and the second level of buoyancy water is discharged to the lower level of the lifting bucket and the buoyancy bucket by the method of "five four to four four". The buoyancy water compartment is discharged to the lower secondary lift bucket and buoyancy bucket. In this way, there are 40 water lifting points in the negative level, and a multi-stage buoyancy barrel 1 and a multi-stage lifting barrel 2 corresponding to the number of buoyancy barrels of the negative level are also installed on the wall, and the 40 water lifting points adopt "five" The way to rise and retreat is to send the water to the height of power generation. Similarly, a multi-stage buoyancy bucket 1 and a multi-stage lifting bucket 2 corresponding to the number of negative secondary buoyancy buckets are installed on the wall, and 40 water lifting points of the negative secondary are also adopted with "five liters and one retreat four". The way the string is sent to the power generation level step by step. The negative first stage and the negative second stage use the "five four changes four four" way to the lower level to the negative three level and the negative four levels, so that the negative three and negative four levels become 32 water lifting points, so that It became the height of two 32-string water lifting devices to send water up the ladder to the power generation point. After entering the negative level, the height of 1 meter falls, and the evolution of n five "four fours and four fives" is passed until the last part of the tail water is left, and then the water is pumped into the lake pond. Finally, all the negative stages formed a 386 string water lifting device, plus the front 50 strings, a total of 436 water lifting devices for the upper reservoir.

The working principle of the invention is as follows:

Hutang Water 10 first injects 1 part of 1.2033 tons of water into the first stage lifting bucket 2-1, and then injects 4 parts into the first stage buoyancy barrel 1_1, a total of 4. 8132 tons of water, in the process, the first The level lifting bucket 2-1 is continuously improved. When the first stage buoyancy bucket 1-1 is filled with 4 parts of water, the water level sensor detects that the water level information is transmitted to the control device, and the first level lifting bucket 2-1 is opened by the control device. The water inlet switch of the drain switch and the second-stage lifting bucket 2-2, the first-stage lifting bucket 2-1 injects a water into the second-stage lifting bucket 2-2 at a speed of 200 kg per second, realizing the first stage Upgrade.

After the first stage lifting bucket 2-1 releases the water, the 4.132 tons of buoyancy water in the first stage buoyancy bucket 1-1 is injected into the negative secondary lifting bucket 2-2-1 at a rate of 200 kilograms per second, and then Refill the negative secondary buoyancy bucket 1-2-1, the first stage of buoyancy bucket 1-1 After the buoyancy water is released, the lake pond water is injected into the first-stage lifting bucket 2-1 to inject 1 part of water, and the first-stage buoyancy bucket 1-1 is filled with 4 parts of water. The above steps are repeated, and the first-stage lifting bucket 2- 1 5 times of water is added to the second-stage lifting bucket 2-2, 5 parts of water, 4 of which water flows into the second-stage buoyancy bucket 1-2, when the second-stage buoyancy bucket 1-2 is filled with 4. 8132 tons In the case of water, the control device opens the drain switch of the second-stage lifting bucket 2-2 and the water inlet switch of the third-stage lifting bucket 2-3, and the second-stage lifting bucket 2-2 goes to the third level at a speed of 200 kg per second. The lifting bucket 2-3 injects a piece of water to achieve a second level of lifting.

After the second stage lifting bucket 2-2 releases the water, the 4. 8132 tons of buoyancy water in the second stage buoyancy bucket 1-2 is first injected into the negative first lifting bucket 2-1-1 at a rate of 200 kilograms per second, and then Refilling the negative first stage buoyancy barrel 1-1-1; after the buoyancy water in the second stage buoyancy barrel 1-2 is released, the first stage lifting barrel 2-1 is further injected into the second stage lifting barrel 2-2, The secondary lifting bucket 2-2 receives the fifth release of the first-stage lifting bucket 2-1 again, and the second-stage lifting bucket 2-2 again injects a water into the third-stage lifting bucket 2-3, repeating the above steps, The second lifting bucket 2-2 is upgraded five times to the third level lifting bucket 2-3 to inject five parts of water, of which 4 parts of water flow into the third stage buoyancy barrel 1-3, when the third stage buoyancy barrel 1-3 When 4,132 tons of water is filled, the control device opens the drain switch of the third-stage lifting bucket 2-3 and the water inlet switch of the fourth-stage lifting bucket 2-4, and the third-stage lifting bucket 2-3 is 200 kg per second. The speed is injected into the fourth stage lifting bucket 2-4 to inject a piece of water to achieve a third level of lifting.
