Description
A HYDRO-PNEUMATIC POWER GENERATION SYSTEM[Field of the Invention]
[0001] The present invention refers to the field of electrical energy, more specifically refers to a hydro-pneumatic power generation system with a simple structure, easy to build at low cost, does not require high technology in construction and creates optimal effectiveness and most stable power generation.[Description of the Related Art]
[0002] Basically, electricity is produced when mechanical energy is harnessed and used to rotate a turbine. In particular, the mechanical energy to rotate the turbine can come from various different sources including: water source, wind source, heat source generated by burning fossil fuels (e.g. coal...) or by nuclear reactions.
[0003] Currently, water sources for dam construction are limited by many factors such as the environment and climate change. In addition, not all countries have natural water sources. As for, coal-fired power is also gradually being replaced due to environmental problems and the depletion of fossil fuels.
[0004] A number of countries have developed hydro-pneumatic power generation systems such as using ocean wave energy, however these systems are relatively complex, require high construction costs, high-level engineering and installation.
[0005] Recently, hydro-pneumatic technology has been researched and developed in power generation applications. Specifically, using the force of floating (with gas) and sinking (with liquid - water) of the float to create torque for the generator. However, conventional hydro-pneumatic technology still has some disadvantages that make the generated electricity unstable because the mechanical energy generated to rotate the generator is not stable, means that there is a delay and rapidity of the generator torque supplied to the generator.
[0006] Specifically, as shown in Fig.l, the float ball K of the conventional hydro-pneumatic technology is structured with a circular shaped exhaust / supply hole KI. In order to exhaust / supply liquid / gas quickly and easily, the size of theround hole KI is increased, this creates space S inside the ball, during operation in each liquid / gas discharge / supply cycle, there will be a mixture of gas and liquid (i.e., not completely gas / liquid) or no gas / liquid in the gap S, which causes the floating and sinking of the float ball K to change at each cycle, making the torque generated unstable.
[0007] In fact, a typical hydro-pneumatic power generation system is composed of numerous K float balls (for example, about 40 to 60 float balls), so the more balls, the greater the error (difference) of movement (floating and sinking), otherwise, there is a delay and rapidity in the movement of torque, so the movement of mechanical energy is unstable.
[0008] Therefore, there is a need for a new power generation system that overcomes the above limitations but provides optimal, stable power generation efficiency, with little impact and dependence on natural conditions, especially with low reasonable construction costs, does not require high techniques, technology and quality materials.[Disclosure][Technical Problem]
[0009] An object of the present invention is to provide a brand new hydropneumatic power generation system to achieve optimal power generation efficiency and stability, to have reasonable construction costs and easy to build with available materials, to be disassembled conveniently and easy to transport.
[0010] To achieve the above-mentioned object, according to one of the preferred embodiments of the invention, a hydro-pneumatic power generation system is composed of the following parts: at least a water tank (1) is constructed as a vertical structure and contains water; at least one hydro-pneumatic mechanism generating mechanical energy (2) is correspondingly arranged inside the water tank (1); at least the acceleration gearbox (3) is arranged with the input connected to the output of the hydro-pneumatic mechanism generating mechanical energy (2); and at least one generator (4) correspondingly driven by ahydro-pneumatic mechanism generating mechanical energy (2) through an acceleration gearbox (3), wherein:
[0011] The hydro-pneumatic mechanism generating mechanical energy (2) is structured to include: a chain gear set (21) arranged to rotate inside the water tank (1) and includes two pairs of gears ( 21a) are arranged in parallel at the two ends of the water tank (1) by two rotating shafts (21b) to be able to rotate, two chains (21c) are sealed into two pairs of gears (21a), respectively; many open floats (22) arranged permanently and at predetermined distances on two chains (21c) through mounting ears (2 Id); the air supply distributor (23) is fixed to one side of the gear (21a) at the lower end of the water tank (1); The air compressor is connected to the air supply distributor (23) to supply air to the air supply distributor (23); and each open float (22) is constructed in the form of a horizontal hollow circular cylinder, including: many openings (22a) are created in a horizontal rectangular shape along the horizontal surface of the circumference of the hollow circular cylinder body; The air supply nozzle (22b) is arranged on one side of a horizontal hollow cylindrical body, in which the air supply nozzle (22b) has an outer end (22b 1) in an L shape and an inner end (22b2) with an L shape extending nearly to the opposite inner circumferential face of the open float (22).The effectiveness of the invention
[0012] With the structure of the open float (22), the openings (22a) in horizontal rectangular shape have two curved leading edges, thereby do not create a gap S like conventional hydro-pneumatic technology because of the short rectangular side of the openings (22a) does not move downward like a circle; Furthermore, the inner end (22b2) of the air supply nozzle (22b) extends close to the inner circumference on the opposite side. When the air is supplied, it will create a vortex starting close to the inner surface to push the water out fastest, so the operation of generating mechanical energy is stable and the generator operates stably.[Brief Description of Drawings]

[0020] In the following, the present invention will be described in detail through preferred embodiments of the present invention and attached drawings, but it should be understood that the invention is not limited thereby. The attached drawings merely illustrate the principle and technical nature of the invention, moreover the description only reveals the technical features of the invention, so in reality there may be many parts / other common details are often changed or modified to be equivalent but do not exceed the scope of the invention as clearly defined in the attached claims.
[0021] Before the technical nature of the invention is described in detail, the invention unifies the following terminology and technical principles:
[0022] The term "hydro-pneumatic" used here is understood to mean using liquid or gas such as water and air, such as air through the process of supplyingand discharging air into / out to emply floats to float and sink by Archimedes' law to generate mechanical energy, is the rotation of torque to rotate a turbine to generate electricity.
[0023] T echnical principle : Whether the electricity generation activity or the generated electrical products are stable in voltage or not, currently depends most on the mechanical energy (torque rotation) created by the supply and discharge liquid (water) and gas (air).
[0024] As shown in the drawings from Fig.2 to Fig.4, the hydro-pneumatic power generation system according to the invention is structured to include: two water tanks 1 which are vertically structured and contain water; two hydropneumatic mechanism generating mechanical energy 2 are respectively arranged inside the two water tanks 1 ; two sets of acceleration gearboxes 3 are respectively arranged with the inlet connected to the outlet of the two hydro-pneumatic mechanism generating mechanical energy 2; and two generators 4 are respectively driven by the two hydro-pneumatic mechanism generating mechanical energy 2 through the two sets of acceleration gearboxes 3.
[0025] As shown in Fig.3 and Fig.4, each water tank 1 is constructed as a vertical cylindrical structure with a rectangular cross- section, consisting of multiple modules joined together and supported by a bracket 5 and filled with water at a predetermined level. With the multi-module structure, the water tank 1 can be easily disassembled for repair and maintenance.
[0026] As shown in the drawings from Fig.3 to Fig.6, each hydro-pneumatic mechanism generating mechanical energy 2 is constructed as follows: a chain gear set 21 arranged to be able to rotate inside the water tank 1 and includes two pairs of gears 21a arranged in parallel respectively at the two ends of the water tank 1 by two rotating shafts 21b to be able to rotate, two chains 21c are tightly fitted to the two pairs of gears 21a, respectively; a plurality of open floats 22 are fixed and at predetermined distances on two chains 21c through mounting ears 2 Id; an air supply distributor 23 is fixed to one side of the gear 21a at the lower end of thewater tank 1 ; an air compressor (not shown in the drawing) is connected to the air supply distributor 23 to supply air to the air supply distributor 23.
[0027] As shown in Fig.5, the air supply distributor 23 is formed with three air supply manifolds 23a arranged radially at 120 degrees apart and three air supply heads 23b are three corresponding one-way valves that are always in a closed state. As each open float 22 moves through the air supply manifold 23 a, the air supply head 23b engages with the mouth of the air supply nozzle 22b of the open float 22, creating a pressure on the air supply head 23b, which is a oneway valve that is opened to supply air into the open float 22 (which will be described in detail below).
[0028] According to another embodiment of the present invention as shown in Fig.7, the air intake distributor 24 is permanently arranged to one side of gear 21 a at the upper end of the water tank 1 ; The air extractor (not shown in the figure) is connected with the air intake distributor 24 to draw air from the air intake distributor 24. The air intake distributor 24 is structured with three air intake manifolds 24a arranged radially 120 degrees apart and three air intake heads 24b are three corresponding one-way valves that are always in a closed state. According to this option, the water level N in the water tank 1 nearly covers the open float 22 at the highest point (as shown in Fig.7) or can be filled, when each open float 22 moves through the air intake manifold 24a, the air intake head 24b fits into the mouth of the air supply nozzle 22b of the open float 22, creating pressure on the air intake head 24b, a one-way valve that is opened to quickly suck air out of the air. The open float 2) also creates a force to absorb water into the openings 22a faster (will be described in detail below).
[0029] As shown in Fig.6, the open float 22 is constructed in the form of a horizontal hollow circular cylinder, including: four openings 22a are created in a horizontal rectangular shape along the horizontal direction of the surface of the cylindrical body's circumference is hollow; The air supply nozzle 22b is arranged on one side of a horizontal hollow cylindrical body, in which the air supply nozzle 22b has an outer end 2b 1) in an L shape and an inner end 22b2 with an L shapeextending close to the inner circumferential face on the side proximal to the openings 22a.
[0030] With the structure of the open float 22 according to the present invention, the water / gas supply / discharge operation is optimal, specifically: the openings 22a have a horizontal rectangular shape with two leading edges curved so it does not create a gap S like conventional hydro-pneumatic technology because the short rectangular side of the openings 22a does not deepen like a circle (see Fig.6); Furthermore, the outer end 22b 1 of the air supply nozzle 2b is constructed to be short, so air is supplied into the open float 22 quickly, while the inner end 22b2 of the air supply nozzle 22b is pulled closer to the inner circumference on the side closest to the openings 22a, when air is supplied, it will create a vortex starting close to the inner surface to push water out fastest, so the operation of creating The mechanical energy output is stable.
[0031] The following is an example of implementation and operating principle of IMWh power generation with the following technical parameters:
[0032] In which: each 4 generator is a 0.5MWh generator; 3-level acceleration gearbox has an output transmission ratio of 1500 rpm; Hydropneumatic mechanism generates mechanical energy to create torque with a rotation rate of 6-10 rpm, open float size (22) has length x diameter = 1100mm x 750mm and has 4 open holes of size length x width = 150mm x 100mm, and the number of open floats (22) is 50 for each mechanism.The process of generating mechanical energy to drive a generator through an overdrive gearbox
[0033] The cycle of pumping air in and pushing water out of the open floats22 to float the open floats 22 according to Archimedes' law, as shown above in Fig.5, the chain gear set 21 will move clockwise rotation by the Archimedes thrust of the open floats 22 of the previous cycle:
[0034] At position (I), when each open float 2 moves through the air supply manifold 23a, the air supply head 23b fits into the mouth of the air supply nozzle 22b, during the open float 22 process moving from position (I) to position (II) willcreate pressure on the air supply head 23b creating a gap (at this time the rectangular openings 22a will point from straight up and rotate clockwise to point vertically to the bottom of water tank);
[0035] At position (II), the gap between the air supply head 23b of the air supply distributor 23 and the mouth of the air supply nozzle 22b is large enough (one-way valve 3b will open), the gas supply (pumping) and water discharge (pushing) process takes place until the open float 22 moves to position (III) (at this time the rectangular openings 22a will point vertically to the bottom of the water tank 1 ;
[0036] At position (III), the air supply head 23 b of the air supply distributor 23 will separate from the mouth of the air supply nozzle 22b, at this time the water inside the open float 22 will be pushed out completely through the rectangular openings 2a and the open float 22 is filled with gas (at this time the rectangular openings 22a are in a state of vertical orientation to the bottom of the water tank 1 and the float 2) will move to float upward while pulling the chain 21c.The cycle of releasing air and supplying water to the open float 22 to sink the open float 22, as shown in Fig.7 at the upper end of the water tank 1:
[0037] When each open float 2 moves (emerges) out of the water surface of the water tank 1, the rectangular openings 2a come into contact with the outside air and begin to point vertically upward. The gas inside the open float 22 will be discharged (escape) to the outside. With the arrangement of the air intake distributor 24, the gas will be sucked out of the open float 22 faster and completely exhausted;
[0038] When each open float 22begins to be submerged into the water by the rotation of the chain 21c created by the Archimedes thrust, the rectangular openings now point vertically upward (top surface of the tank 1), the water will begin to absorb any water in the open float 22 through the rectangular openings 2a, when the open float 22 is filled with water, it will create gravity to sink its and creating a force to move the chain 21c.
[0039] According to another priority plan there is an air intake distributor 24 arranged in the present invention as shown in Fig.7:
[0040] At position (IV), when each open float 22 moves through the air intake manifold 24a, the air intake head 24b fits into the mouth of the air supply nozzle 22b, during the process of open float 22 moving from position (IV) to position (V), will create pressure on the air supply head 23b creating a gap (at this time the rectangular openings 22a that will move from the left to the right straight up rotate clockwise);
[0041] At position (VI), the gap between the suction head 24b of the air intake distributor 24 and the mouth of the air supply nozzle 22b is large enough (one-way valve 24b will open), the air suction process will take place, in the case of being submerged in water, the process of sucking water into the open float 22 also takes place until the open float 22 moves to position (VI) (at this time the rectangular openings 22a will direct vertically to the top surface of the water tank I;
[0042] At position (VI), the air intake head 24b of the air intake distributor 24 will separate from the mouth of the air supply nozzle 22b, when the open float 22 is filled with water (i.e. the gas will be pushed completely out through the rectangular openings 22a and the air supply nozzle 22b and open float 22 will move downwards by the gravity of the water while pulling the chain 21c creating a torque.
[0043] Mechanical energy generation cycle: The process of rising (air supply and water discharge) and sinking (air discharge and water supply) of the open float 22 takes place continuously and regularly, according to which the chain 21c with open floats 22 will move to rotate the gear pairs 21a, this process creates torque to rotate shaft 2 lb to create mechanical energy for the acceleration gearbox 3.IMWh electricity generation process
[0044] The torque generated by the hydro-pneumatic mechanism generating mechanical energy 2 is supplied to the input of the acceleration gearbox 3 so thatthe output reaches a speed of 1500 rpm (torque force T = 86,200Nm) supplying to the generator (4) to generate electricity.The effectiveness of the invention
[0045] In addition to the special structure of the open float 2, it includes openings 22a that are in horizontally rectangular shape and have two curved leading edges, thereby will not create a gap S like conventional hydro-pneumatic technology because The short rectangular side of the openings 22a does not move downward like a circle; and the inner end 22b2 of the air supply nozzle 22bextends close to the inner circumference on the opposite side and close to the openings 22a so that the operation of the mechanical energy generation and the generator Stable operation is stable.
[0046] Furthermore, with the arrangement of the air intake distributor 24, as soon as the open float 22 sinks in the water, these open floats 22 are filled with water to sink, different from conventional hydro-pneumatic technology. It will take at least a certain amount of time to absorb water to nearly fill the float because the water being sucked in is hindered by the gas inside, which means the first 4-8 floats (from top to bottom) will not be fully filled with water, this causes the torque to decrease (low).
