Description

Technical Field

[0001] The invention relates to a power generation device, in particular to a power generation device which utilizes water buoyancy to perform work. Background Art

[0002] Traditional generators usually rely on thermal, hydro, nuclear and other power generation methods. Currently, energy conservation and environmental protection have become important agendas for countries around the world. People have turned their attention to renewable and sustainable new energy sources such as solar energy, wind energy, and hydropower. Water energy on land, such as water from large rivers and water in the sea, is everywhere. People use high water levels to intercept and build dams in large rivers and build tidal power stations on large beaches. However, these forms of hydropower generation are restricted by the geographical environment, are difficult to build, and have high costs, which greatly wastes water resources.

[0003] In the prior art, a device for generating electricity by utilizing the buoyancy of water in a water tower is disclosed. The invention patent with the publication number CN1338570A discloses a water buoyancy and gravity power generation device and method, which utilizes the buoyancy of water to push the floating ball to a high place. After reaching the top, the floating ball leaves the water and falls to the horizontal plate of the sprocket under the action of gravity, thereby pushing the sprocket to do work and generate electricity. The floating ball enters the water again by a conveying pipe with a receiving groove, that is, after the floating ball falls into the receiving groove, the auxiliary motor pushes the conveying pipe horizontally, thereby sending the floating ball in the receiving groove to the bottom of the water.

[0004] The above power generation device has a key technical link, that is, after the gravity work mode is completed, the float must re-enter the bottom of the water tower to start a new round of buoyancy work mode and the cycle can continue. Therefore, there must be a conveying device to overcome the high pressure at the bottom of the water tower and push the float in. The existing technical solution provides a sealed conveying device structure, which is too complicated and has the problem of leakage. Moreover, the float rises slowly in the water tower, the workmanship is slow, and the power converted into electrical energy is also slow, which greatly limits the implementation and promotion of these technical solutions. Summary of the invention

[0005] The technical problem to be solved by the present invention is to provide a water buoyancy power generation device which can change the power of output electric energy.

[0006] The technical solution of the present invention is: a water buoyancy power generation device, including an upright water tower and a generator set, wherein the water tower contains a solution and is provided with a plurality of floats, the top of the water tower has an opening, and a water storage tank is vertically connected to the bottom thereof, the upper surface of the water storage tank has a notch, and one side of the water storage tank is provided with a propeller; the generator set is arranged in parallel beside the water tower, including two sprockets arranged up and down and a generator, and another chain is sleeved on the two sprockets, and a plurality of baffles are evenly provided on the outer edge of the chain, the solution is salt water, and the side wall of the water tower is connected with an air compression pump for conveying high-pressure air into the water tower.

[0007] A temporary storage room is provided below the water tank, and a water replenishment tank is provided near the top of the water tower, and the two are connected.

[0008] A decompression chamber composed of a first gate valve and a second gate valve is provided on the communication passage between the water storage tank and the water tower.

[0009] A plurality of small iron blocks wrapped by plastic are arranged inside the float.

[0010] A third gate valve is arranged at the notch of the water storage tank.

[0011] The water tower and the water storage tank are cylindrical.

[0012] The technical effect of the present invention is that the present invention completely eliminates the leakage phenomenon by setting up a temporary storage room and a water replenishment tank, which facilitates implementation and promotion. The buoyancy of the float can be changed by adjusting the concentration of the configured salt water; the high-pressure air pumped into the water tower by the high-pressure air pump also changes the buoyancy of the float, thereby changing the time for the float to move to the top of the water tower, thereby changing the time for the float to complete one work and generate electricity, that is, the power generation power can be adjusted.

[0015] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

[0016] See also Figure 1The power generation device of the present invention includes an upright vertical water tower 10 and a generator set on the side. The water tower 10 is filled with salt water, so that the specific gravity of the water increases to 1.03~1.30. A number of floats 12 are placed in the salt water, and a small iron ball is arranged in the float 12 to increase the weight of the float. The float 12 generates an upward buoyancy in the salt water, resisting its own weight, so that the float 12 rises from the bottom of the water tower to the top, thereby increasing its gravitational potential energy. The floats 12 that reach the top of the water tower, under the subsequent arch action of the float 12, fall from the top outlet one after another, thereby converting the potential energy into kinetic energy. A control panel 19 is arranged at the top outlet of the water tower 10 to control the falling time of the float 12.

[0017] The generator set includes two sprockets 21 and 22 vertically arranged above and below and a chain sleeved on the sprockets. The chain is provided with a plurality of baffles 20. When the floating ball 12 falls, it hits the baffles 20, so that the chain drives the sprocket to rotate, and then the lower sprocket 22 drives the generator to work through a high-quality flywheel to generate electricity. The floating ball 12 falls continuously, hits the baffles 20, and continuously drives the flywheel and the generator to work, so that the gravitational potential energy of the floating ball 12 is converted into electrical energy output.

[0018] When the float 12 arrives near the lower sprocket along with the chain, the baffle 20 moves in a circle around the center of the lower sprocket 22, and the float 12 loses its support and has to perform free fall motion.

[0019] At the bottom of the water tower 10, there is a water tank 9 for storing refluxed brine, which is connected to the water tower 9. On their connecting passage, there are the first gate valve 1 and the second gate valve 2 which can be automatically controlled. The cavity between the first gate valve 1 and the second gate valve 2 is equivalent to a decompression chamber. Directly below the free fall trajectory of the float 12, there are buffer plates 7 and the third gate valve 3, respectively. Below the third gate valve 3, there is a cavity for receiving the float. The float 12, which originally has a low initial velocity, falls into the cavity at a lower speed after the buffering effect of the buffer plate 7, under the condition that the third gate valve 3 has been automatically opened. On one side of the cavity, there is a propeller 8, which can push the float 12 into the above-mentioned decompression chamber, and then close the second gate valve 2 and open the first gate valve 1. Under the action of buoyancy, the float 12 joins the journey of rising again. This cycle is repeated to continuously generate electrical energy.

[0020] In the above process, the first gate valve 1, the second gate valve 2 and the third gate valve 3 are opened and closed automatically continuously, which can ensure that the energy consumption cost of the float 12 entering the bottom of the water tower through the decompression chamber is the minimum, but the problem of brine reflux is left. Below the water storage tank 9, there is a first temporary storage chamber 4, and the refluxed brine first enters the first temporary storage chamber 4 for temporary storage. Inside the water storage tank 9, there is an overflow valve 5. When the refluxed brine is too much, the overflow valve is activated, and the brine in the first temporary storage chamber 4 is extracted to the second temporary storage chamber 15 arranged near the top of the water tower. When the water in the water tower 10 is driven by the float 12 to overflow the remaining water, the overflowed brine can enter the overflow tank 14 again. When the brine in the second temporary storage chamber 15 is too much, the brine is extracted to the top of the water tower 10, thereby ensuring that the water level 13 of the brine in the water tower 10 remains unchanged.

[0021] The outer bucket of the small iron block in the float ball 12 is wrapped with plastic, which can prevent the impact of the float ball during its falling process from damaging the float ball surface.

[0022] In addition, an air compression pump 17 and an air inlet valve 18 are provided on the side wall of the water tower, which can allow compressed air to continuously enter the salt water, which can increase the buoyancy of the float and accelerate the rising speed of the float, thereby increasing the power generation, which has a very beneficial technical effect.

Although the present invention has been disclosed as a preferred embodiment as above, it is not used to limit the present invention.
