Description

Technical Field

[0001] The invention relates to a power generation device, in particular to a buoyancy power generation device. Background Art

[0002] The growing demand for energy around the world has made various power generation technologies an important research direction in the energy field. Among the existing power generation methods, thermal power generation based on fossil fuels still occupies a dominant position. However, thermal power generation consumes a large amount of fossil fuels, such as coal, oil and natural gas. These fossil fuels are non-renewable, and the combustion process will produce a large amount of carbon dioxide and other pollutants, leading to environmental pollution and the intensification of the greenhouse effect, which does not meet the needs of sustainable development.

[0003] At the same time, in order to reduce dependence on fossil fuels, clean energy technologies such as hydropower and wind power have gradually become important alternatives. Although these methods are more environmentally friendly than thermal power generation, they also have great limitations in practical applications, especially in terms of power generation stability: 1. Hydropower is subject to regional and seasonal restrictions on water resources: Hydropower uses the kinetic energy or potential energy of water flow to generate electricity. Although it does not produce greenhouse gas emissions, its power generation is significantly affected by the supply of water resources. In the dry season or in arid areas, the water flow of hydropower plants is reduced, making it difficult to meet normal power generation needs. In addition, hydropower also requires large-scale reservoir construction, which may affect the balance of the ecosystem and bring environmental impacts. Especially in areas with significant seasonal precipitation changes, it is difficult for hydropower generation to remain stable, causing uncertainty in the power supply system.

[0004] 2. Wind power generation relies on natural wind conditions: Wind power generation drives the wind rotor to rotate and drives the generator to generate electricity, which is a typical renewable energy source. However, wind power generation has high requirements for wind speed. If the wind speed is too low, it cannot generate electricity normally, and if the wind speed is too high, it may damage the equipment. Therefore, wind power generation is usually suitable for areas with abundant wind resources, such as coastal areas and mountainous areas. Even in these areas, due to the daily changes in wind speed and wind direction, the output power of wind power generation fluctuates greatly, and it is impossible to guarantee continuous and stable power generation, which easily causes unstable power supply.

[0005] 3. Existing technologies are difficult to provide stable power output. Generally speaking, existing power generation methods have certain limitations: traditional thermal power generation relies on fossil fuels, causing environmental pollution and resource consumption; although hydropower and wind power are clean energy, they are greatly affected by natural conditions, and the power generation fluctuates greatly with seasonal and climate changes. They cannot provide stable power output and cannot fully meet the modern society's demand for high-stability power supply. Therefore, it is necessary to make further improvements to them. Summary of the invention

[0006] The purpose of the present invention is to overcome the shortcomings of the existing technology and provide a buoyancy power generation device with simple structure and convenient use, which can achieve stable power generation output by utilizing the buoyancy change of the floating body in the water, and at the same time improve the energy conversion efficiency and operability of the device. The device can accurately control the buoyancy change of the floating body through gas injection and water flow control system, thus overcoming the problem of unstable buoyancy control in the prior art, and thus can be a buoyancy power generation device that can operate continuously under conditions with small environmental changes.

[0008] Furthermore: the first valve plate is covered and installed on the first air pumping port, and a first valve port is arranged on the first valve plate. When the first valve plate moves, the first valve port overlaps or is misaligned with the first air pumping port, so as to realize the opening and closing of the first air pumping port.

[0009] Furthermore: the second valve plate is installed to cover the first drain outlet, and a second valve port is arranged on the second valve plate. When the second valve plate moves, the second valve port overlaps or is misaligned with the first drain outlet to realize opening and closing of the first drain outlet.

[0010] Furthermore: the air box is provided with two sets installed side by side, the first valve plates on the two sets of air boxes are connected by a first linkage rod, so that the two sets of first valve plates move synchronously; the second valve plates on the two sets of air boxes are connected by a second linkage rod, so that the two sets of second valve plates move synchronously.

[0011] Furthermore: the first driving mechanism and the second driving mechanism are turntables driven by reduction motors, and a pull rod is hingedly installed on the turntable, and the other end of the pull rod is hingedly connected to the first valve plate or the second valve plate.

[0012] Furthermore: the air pump box is connected to a return water tank, and the water discharged from the air pump box enters the return water tank. A return water device is installed in the return water tank and connected to a water storage barrel, so that the water in the return water tank is discharged into the water storage barrel for recycling.

[0013] Furthermore: the water return device includes a water return bracket, a first water return gear is installed on the top of the water return bracket, a second water return gear is installed on the bottom of the water return bracket, the first water return gear and the second water return gear are connected by a water return chain and connected to the water return drive mechanism, and a plurality of water return spoons are installed on the water return chain. After the water return spoon is filled with water from the water return pool, it is poured into the water storage bucket.

[0014] Furthermore: the water return drive mechanism is a water return drive motor connected to the first water return gear or the second water return gear.

[0015] The beneficial effects of the present invention are: 1. Simple structure, low production cost and improved market competitiveness.

[0016] 2. The present invention can achieve precise air injection by setting a one-way valve and an air pump inside the pontoon, so that the water in the pontoon is discharged, generating stable and controllable buoyancy. Compared with the buoyancy power generation method that relies on water level fluctuations in the prior art, the buoyancy control of the device is more stable, achieving controllable buoyancy and sinking of the pontoon, ensuring that the power generation device maintains continuous and stable power generation output for a long time.

[0017] 3. The present invention uses the buoyancy chain to drive the synchronous movement of the sprocket and the generator. When the buoyancy rises, it can effectively convert the buoyancy into mechanical energy and drive the generator to generate electrical energy. At the same time, the device structure is equipped with a transmission chain and other designs, which makes the conversion of buoyancy and mechanical energy more efficient, reduces energy loss, and improves the overall power generation efficiency.

[0019] 5. Since the device does not rely on external natural resources such as water flow or wind power, but drives power generation through the change of buoyancy of the pontoon, it can operate independently in relatively closed waters and is not affected by seasons or weather. This advantage makes the device more superior in environments that require stable power output, such as areas lacking water flow, and is an efficient and stable clean energy power generation solution.

[0024] The present invention is further described in detail below with reference to the accompanying drawings. A buoyancy power generation device includes a bracket 1 installed in a water storage barrel 4, a first sprocket 11 is installed at the bottom of the bracket 1, and a second sprocket 12 is installed at the top of the bracket 1; a buoyancy chain 13 is installed between the first sprocket 11 and the second sprocket 12, and the buoyancy chain 13 drives the first sprocket 11 and the second sprocket 12 to move synchronously; a plurality of buoyancy boxes 2 are installed on the buoyancy chain 13; The buoyancy box 2 is open, and a one-way valve 21 is installed at the bottom of the buoyancy box 2 to open when it moves toward the inside of the buoyancy box 2; The first sprocket 11 or the second sprocket 12 is connected to a generator; The bottom of the bracket 1 is provided with an air inlet connected to the air inlet device, and the air outlet of the air inlet is located on the rising side of the pontoon 2; the air inlet device discharges air from the air inlet, and the air enters the pontoon 2 when it moves upward, and the water inside the pontoon 2 is squeezed out of the pontoon 2 by the air, so that the pontoon 2 generates an upward buoyancy, and when the pontoon 2 floats upward, the first sprocket 11, the second sprocket 12 and the generator are driven to move through the pontoon chain 13 to achieve the purpose of power generation; The inflation device includes an inflation box 6, a first inflation port 61 is provided on the top of the inflation box 6 and is connected to the bottom of the water storage barrel 4, a first valve plate 62 is installed on the first inflation port 61, the first valve plate 62 is connected to a first driving mechanism, the first driving mechanism pushes the first valve plate 62 to move, so as to open or close the first inflation port 61; a first drain port 63 is provided at the bottom of the inflation box 6 and is connected to the atmosphere, a second valve plate 64 is installed on the first drain port 63, the second valve plate 64 is connected to the second driving mechanism, and the second driving mechanism pushes the second valve plate 64 to open or close the first drain port 63.

[0025] In one embodiment, the first valve plate 62 is covered and installed on the first air inlet 61. The first valve plate 62 is provided with a first valve port 65. When the first valve plate 62 moves, the first valve port 65 overlaps or is misaligned with the first air inlet 61 to open and close the first air inlet 61.

[0026] In one embodiment, the second valve plate 64 is installed to cover the first drain port 63, and the second valve plate 64 is provided with a second valve port 66. When the second valve plate 64 moves, the second valve port 66 overlaps or is misaligned with the first drain port 63 to open and close the first drain.

[0027] In one embodiment: the air box 6 is provided with two sets installed side by side, and the first valve plates 62 on the two sets of air boxes 6 are connected by a first linkage rod 67, so that the two sets of first valve plates 62 move synchronously; the second valve plates 64 on the two sets of air boxes 6 are connected by a second linkage rod, so that the two sets of second valve plates 64 move synchronously.

[0028] In one embodiment, the first driving mechanism and the second driving mechanism are a turntable 7 driven by a reduction motor, a pull rod 71 is hingedly mounted on the turntable 7, and the other end of the pull rod 71 is hingedly connected to the first valve plate 62 or the second valve plate 64.

[0029] like Figure 5 As shown, in one embodiment: the air pump box 6 is connected to the return water tank 8, the water discharged from the air pump box 6 enters the return water tank 8, and the return water tank 8 is installed with a return water device 9 connected to the water storage barrel 4, so that the water in the return water tank 8 is discharged into the water storage barrel 4 for recycling.

[0030] In one embodiment: the water return device 9 includes a water return bracket 91, a first water return gear 92 is installed on the top of the water return bracket 91, a second water return gear 93 is installed on the bottom of the water return bracket 91, the first water return gear 92 and the second water return gear 93 are connected by a water return chain 94, and are connected to the water return drive mechanism, and a plurality of water return scoops 95 are installed on the water return chain 94, and the water return scoops 95 scoop water from the water return pool 8 and pour it into the water storage bucket 4.

[0031] In one embodiment, the water return drive mechanism is a water return drive motor connected to the first water return gear 92 or the second water return gear 93 .

[0032] Working principle: Several pontoons 2 are provided in the device, each of which is connected by a pontoon chain 13, and the pontoon chain moves up and down along the path between the first sprocket 1 and the second sprocket 12. On the rising side of the pontoon chain, air is injected into the pontoon through the air pump and the air pump. The air outlet of the air pump is located at the lower part of the pontoon. When the air rises and enters the pontoon, the water in the pontoon is discharged, thereby increasing the buoyancy of the pontoon and making the pontoon float upward. When the pontoon floats upward, it drives the pontoon chain 13, which in turn drives the sprocket to rotate.

[0033] The buoy chain drives the first sprocket and the second sprocket to move synchronously, and the sprocket generates electricity by connecting to the generator. When the buoy rises along the chain under the action of buoyancy, the mechanical energy generated is transmitted to the generator through the sprocket, converting the buoyancy into electrical energy output. At the same time, when the buoy reaches the water surface, the one-way valve opens, and air enters the buoy to break the vacuum inside the buoy. The buoy leaves the water surface driven by the chain and finally enters the descending side of the chain. On the descending side of the buoy, the one-way valve is always in an open state, so that the buoy can enter the water smoothly, and the buoy on the descending side does not generate buoyancy, and the opening of the one-way valve allows the water flow to be discharged smoothly through the one-way valve, thereby reducing the resistance of the buoy during the descent process. When the buoy crosses the lowest point and enters the ascending side, the one-way valve is closed at this time, and air enters the buoy to achieve a circular motion and maintain the continuity of the power generation process.

[0034] like Figure 1-4As shown, it is a schematic diagram of the structure of the air pumping device in this case. The air pumping device described in this embodiment includes an air pumping box 6, the top of the air pumping box 6 is provided with a first air pumping port 61 connected to the bottom of the water storage tank, a first valve plate 62 is installed on the first air pumping port 61, the first valve plate 62 is connected to the first driving mechanism, the first driving mechanism pushes the first valve plate 62 to move, and realizes opening or closing the first air pumping port 61; the bottom of the air pumping box 6 is provided with a first drain port 63 connected to the air pumping, a second valve plate 64 is installed on the first drain port 63, the second valve plate 64 is connected to the second driving mechanism, and the second driving mechanism pushes the second valve plate 64 to open or close the first drain port 63. When pumping air, the first valve plate is closed first, and the second valve plate is opened, so that the water in the pumping box is discharged into the return pool, so that air enters the inside, and then the second valve plate is closed, and the first valve plate is opened, so that the water in the water storage barrel enters the pumping box through the first pumping port, so that the air in the pumping box is squeezed, and the air enters the water storage barrel through the first pumping port. When the air rises, it can also enter the inside of the float box, and the water in the float box is discharged, thereby increasing the buoyancy of the float box and making the float box float upward. When the float box floats upward, it drives the float box chain 13, and then drives the sprocket to rotate. When the water in the pumping box is filled, the first valve plate is closed, and the second valve plate is opened, and the water in the pumping box is emptied again, and the air re-enters the pumping box, and then the second valve plate is closed, and the first valve plate is opened. In this way, the air can be continuously pumped into the float box, so as to push the float box to rise.

[0035] like Figure 5 As shown, in the above embodiment, the water generated during the pumping process will be discharged to the pumping box 6, and the pumping box collects the discharged water into the return water tank 8 through the return water system. The return water tank is equipped with a return water device 9, which transports water to the water storage bucket 4 through the return water chain 94 and the return water scoop 95 to achieve water recycling. Specifically, the return water drive motor drives the return water chain to reciprocate through the first return water gear 92 or the second return water gear 93, thereby driving a number of return water scoops 95 to scoop up water from the return water tank. When the return water scoop rises to the highest position, the return water scoop reverses and pours the water into the water storage bucket 4. This design ensures the continuous operation of the device in a water-deficient environment while avoiding the waste of water resources.

[0036] Compared with traditional water buoyancy power generation devices, the buoyancy of this device changes evenly during the rising and sinking process, ensuring the continuous operation of the sprocket and generator, providing stable power output and meeting the needs of different industries for stable energy.

[0037] At the same time, the device drives the sprocket through the buoyancy chain, and the efficiency of converting buoyancy into electrical energy is improved. The rationally designed sprocket and generator connection structure ensures that the rising torque of the buoyancy is directly transmitted to the generator, reducing energy loss and thus improving power generation efficiency. This design better overcomes the problem of large energy loss in existing buoyancy power generation devices and makes the power generation process more efficient.

[0038] In addition, the power generation device is not affected by external natural conditions such as water flow, wind speed or light, and can operate independently through the internal buoyancy adjustment system. Therefore, the device is suitable for environments with relatively stable water flow or closed environments, avoiding the limitations of existing hydropower and wind power generation affected by seasons and weather, and can provide stable and continuous power output, so it can be widely promoted and used.

[0039] The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention. It should be understood by those skilled in the art that the present invention is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention may have various changes and improvements, and these changes and improvements all fall within the scope of the present invention to be protected.
