Background Art

[0002] The mineral energy that can be developed and utilized on the earth is limited. With the increasing energy consumption of human beings, mineral energy is becoming increasingly exhausted. Seeking sustainable green energy alternatives is a goal that humans are constantly pursuing. Natural hydropower resources, solar energy, wind energy, tidal energy, etc. are all sustainable green energy. However, these energy sources are subject to the influence of natural conditions, uneven distribution in time and space, and there are still many defects in the existing energy utilization technology, and the utilization efficiency is low, which has brought many difficulties to the comprehensive utilization and popularization of human green energy.

[0003] Water can carry a boat, but it can also capsize it. Water has the power of moving water, and it also has the power of still water. As a clean energy source, water contains huge buoyancy energy. However, the buoyancy energy of water has not been used more widely and efficiently. So far, the ways and means of using buoyancy energy are still mainly limited to 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 widespread industrial application. In today's increasingly scarce energy, the development of technologies that can fully utilize the buoyancy energy of liquids to convert it into other directly usable energy, such as mechanical energy or electrical energy, to more conveniently serve human production and life has broad sociological and economic significance. 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 national invention patents, such as 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 and 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 to the outside. After years of dedicated experimental research, the inventor has continuously optimized the technical solution for buoyancy energy conversion and utilization. Practice has proved that the technical solutions of these inventions still have a lot of room for improvement and optimization, which can further improve the conversion efficiency of buoyancy energy, and then improve the efficiency and effect of power conversion and output, so as to make up for the shortcomings of insufficient utilization of buoyancy energy in existing technologies, and allow static water energy to be utilized more efficiently like natural hydraulic energy.

[0019] The energy cabin 4 includes a brake cabin 41 at the proximal end, a power cabin 42 at the middle section and a guide cabin 43 at the distal end, and adjacent cabins are sealed and connected via flanges 44 .

[0023] The power device guide rail 11 provided in the energy cabin 4 has its axial end extending into the brake cabin 41 and its outer circular end extending into the guide cabin 43 .

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

[0030] The present invention is based on the fact that the buoyancy devices in the multiple energy cabins evenly distributed on the rotary power device are in different positions under the buoyancy of water, so that the entire power device is in a "quasi-steady state", and the energy cabin is always in an upward trend, so that the center of gravity of the buoyancy devices in the eight energy cabins of the power device in different positions is on different circumferences with the power axis as the center. Since the active buoyancy device 12 and the auxiliary buoyancy device 14 in the energy cabin both have large energies and play an active role, the passive buoyancy device 13 has small energy and is in a passive cooperative operation state; when a group of energy cabins is in a vertical state, the active buoyancy device 12 and the auxiliary buoyancy device 14 therein are lifted upward, and through the pulling action of the transmission soft rope 16, the passive buoyancy device 13 is pressed downward and sinks. The passive buoyancy device 13 in the lower energy cabin falls to the lower position in the empty cabin state, forming a downward light situation. At this time, the active buoyancy device 12 and the auxiliary buoyancy device 14 in the upper energy cabin also float upward, and thus press the passive buoyancy device 13 downward, forming an upper-heavy situation with the empty cabin downward and the water level upward. Therefore, the power of the power system of the present invention comes from the energy conversion between the buoyancy energy of the water in the energy cabin and the mass of the object. Through the input of the initial hydraulic energy of the system, the system is adjusted to a "quasi-steady state" of "heavy on top and light on the bottom". The buoyancy energy is converted into the potential energy of the mass of the object. The potential energy of the objects (mass) in the grouped energy cabins is converted in sequence, driving the rotary power device to drive the power shaft to rotate, just like an acrobat steps on the inner wall of the roller to drive the roller to rotate, and the rotation of the roller forms a driving force. The engine is driven to generate electricity through mechanical energy and output power to the outside. The inventor calls it a mass-energy conversion power machine.

[0031] Working process of the present invention:

[0032] Preparation before starting the system: Carefully and meticulously check the status of various components of the power generation and power conversion system, as well as the quality of accessories, to see if they meet the start-up requirements. Once they meet the design standard, you can start the system. First, tighten the brakes, then open the inlet and outlet valves, and fill the energy cabin with water through the inlet and outlet valves. At the same time, remove the gas in the cabin. After the cabin is full of water, close the inlet and outlet valves and inlet and outlet valves on the energy cabin. Fill each energy cabin with water one by one, and the power unit will enter the working preparation state.

[0033] The position of each buoyancy device in the energy compartment is adjusted by the brake device. First, adjust each power device in the energy compartment at the lower position: adjust the active buoyancy device 12 to the high position, the passive buoyancy device 13 to the low position, and the auxiliary buoyancy device 14 to the upper position. Then, adjust each power device in the energy compartment at the high position: adjust the active buoyancy device 12 to the low position, the passive buoyancy device 13 to the lower position, and the auxiliary buoyancy device 14 to the upper position. In this way, the two vertically opposite energy compartments make the system in a "top-heavy and bottom-light" state (such as Figure 1 According to this rule, adjust the other energy cabins to this state. The brake system is used to maintain this "ready to go" high potential energy storage state, that is, the power generation system is ready to work and ready to start; the power conversion output system is also in good condition.

[0034] System operating status (power conversion and output)

[0035] Control the brake device so that the power device loses its constraint and rotates in a clockwise direction. When the energy cabin is in a vertical state, the active buoyancy device 12 and the auxiliary buoyancy device 14 in the upper energy cabin are lifted upward, and the passive buoyancy device 13 is pressed downward and settled by the pulling action of the transmission soft rope 16. The passive buoyancy device 13 in the lower energy cabin falls to the lower position when the cabin is empty, forming a light situation at the bottom. The active buoyancy device 12 and the auxiliary buoyancy device 14 in the upper energy cabin also float upward at this time, and the passive buoyancy device 13 is pressed down with the cabin, forming a heavy situation with the cabin empty and the water level upward. When the positions of the buoyancy devices in the upper energy cabin are exchanged in place, the brake system in the brake cabin 41 is automatically locked. Until the upper energy cabin rotates 180 ° to the lower position of the vertical state, the brake system in its brake cabin is automatically unlocked. Correspondingly, after the buoyancy device position conversion in the upper energy cabin is transferred, the brake system is locked again. The whole system operates under programmed automatic control. Each energy compartment group rotates in turn in a cycle, driving the power machine to rotate during the buoyancy energy conversion, driving the power shaft to transfer power to the power conversion system, and driving the generator to generate electricity.
