[0002] Traditional mineral energy is constantly being consumed and depleted, but the energy consumed by human activities is increasing. Seeking sustainable green energy is a goal that humans are constantly pursuing. Natural hydropower resources, solar energy, wind energy, tidal energy, etc. are all sustainable energy sources, but these types of energy are subject to the influence of natural conditions and are unevenly distributed, either unevenly distributed in time or unevenly distributed in space. There are also unstable natural deficiencies. All of these have brought certain difficulties to human use.

[0003] Water resources are abundant and have huge energy. The utilization of natural water energy is limited by nature and is seriously unevenly distributed. Water can carry a boat, but it can also capsize it. In other words, water has both the energy of moving water and the energy of still water. As a clean energy source, water contains huge buoyancy energy. However, the buoyancy energy of water has not been effectively utilized, and the way to utilize buoyancy energy is still mainly in the field of transportation. There are still few devices in the existing technology that can convert buoyancy energy into other forms of energy for utilization, and there is no industrial application. In today's increasingly scarce energy, it is of broad sociological and economic significance to develop a device that can fully utilize the buoyancy energy of liquids and convert it into mechanical energy for utilization or further use it in power conversion devices, such as power generation devices. The inventor has developed a number of devices that use buoyancy to convert mechanical energy and even electrical energy, and has applied for a number of invention patents: a vertical gravity pressure type large-capacity liquid high-efficiency pumping device (ZL2014102484112); a hydraulic self-floating large-capacity high-lift water lifting device (2L2015103762285); a hydraulic self-floating high-efficiency power conversion output device (ZL2015103762872); a floating lifting type large-capacity high-lift liquid high-efficiency pumping device (ZL2015100223080), which uses buoyancy and gravity to do work and output power devices. After years of dedicated research and experimental testing, the inventor has continuously optimized the technical solutions. The technical solutions of these inventions can be further optimized to improve the conversion efficiency of buoyancy energy and further improve the power output effect. Summary of the invention

[0029] Working principle and working process of the present invention:

[0030] The present invention is based on the principle of buoyancy lifting and negative pressure suction. It uses the lifting effect of the pump plug buoyancy tank to form negative pressure at the bottom of the pump body, pumping the water in the water collection tank into the pump body, and then entering the potential energy tower through the water riser grid and the water lifting grid, and rising into the potential energy tank to form high potential energy water, and impacting the power conversion device through the potential energy water pipe to achieve power conversion and output to the outside. If it impacts the turbine, it can generate electricity, and the tail water flows into the return water tank to enter the next working cycle.

[0031] Before the device of the present invention works, the system is in a state where the potential energy tower 1, the potential energy chamber 101, the water lifting chamber 2 and the buffer water chamber 14 are all filled with water, the gate lift valve F1, the plug lift valve F3, the water collecting valve F5 and the water collecting valve F6 are in a closed state, the gate sinking valve F2 and the plug sinking valve F4 are in an open state, and the pump plug 7 and the isolation sleeve 8 are both in the lower position.

[0032] During operation: first open the rising plug valve F3, the water collecting valve F5, and the water collecting valve F6, and close the sinking plug valve F4 (the rising gate valve F1 is closed, the sinking gate valve F2 is opened, and the sealing sleeve 8 is in a low position to block the water-rising grid 11). The return water tank 24 is connected to the buffer water tank 14, and the buffer water tank 14 is connected to the water collecting tank 4; at this time, the water in the return water tank 24 enters the pump plug auxiliary tank 18, and the pump plug buoyancy tank 20 therein rises under the buoyancy of the water, and at the same time When the pump plug 7 is raised by the pump plug push rod 13, the water in the water collecting tank 4 is sucked into the pump cabin. When the pump plug 7 is raised to the highest position, the gate valve F1 is opened, the gate valve F2 is closed, the plug valve F3, the water collecting valve F5 and the water collecting valve F6 are closed at the same time, and the sinking plug valve F4 is opened. At this time, the water in the return tank 24 enters the isolation auxiliary tank 17, and the isolation buoyancy tank 19 therein rises under the buoyancy of the water. At the same time, the isolation The push rod 12 drives the isolation sleeve 8 to rise, opens the water outlet of the pump room, and connects the water-rising grid 11. The water in the pump room sinks under the action of gravity as the pump plug buoyancy compartment 20 loses its buoyancy. The water in the pump room enters the water-rising tank 2 through the water-rising grid 11, and then enters the potential energy tower 1 through the water-rising grid 102, thereby pushing the water level in the potential energy tower 1 to rise, overflowing the overflow weir 1011 and entering the potential energy water tank 101, forming high potential energy water, which is converted into mechanical energy or electrical energy through the potential energy water pipe 28 impacting the power conversion device 27. The "disabled" water flows back into the return water tank 24 through the drain pipe 29 and enters the next working cycle: close the lifting valve F1, open the sinking valve F2, let the isolation sleeve 8 return to the low position, and block the water-rising grid; open the lifting plug valve F3, the water collecting valve F5, and the water collecting valve F6, close the sinking plug valve F4, and let the water in the return water tank 24 enter the pump plug auxiliary tank 18 again...

[0033] By repeating this cycle, the low-level water can be continuously raised to a high level, forming high-potential water at the top of the potential energy tower, which is converted into power through a power conversion device (especially convenient for conversion into electricity). That is, the buoyancy energy of water is fully stimulated and utilized, and efficiently converted into potential energy, and then converted into kinetic energy, thereby continuously outputting power to the outside.
