Background

At present, a reservoir or a river-blocking dam is built for storing water and driving a water turbine generator set to generate electricity, and the technology is a mature and common hydroelectric power generation technology. However, strictly speaking, reservoir water only has static gravity, and static water generates no power. Only the moving water can generate electricity. The height drop of the dam creates conditions for water movement. The head effect is imparted by gravitational forces. Therefore, hydroelectric power generation is essentially gravitational power generation. Moving water is the medium that conducts the attractive forces. Wind power generation is also a mature and widespread technology. Wind is air in motion. The power of air is imparted by gravitational and thermodynamic effects, with gravitational forces being dominant. The fluid air is the medium for gravitational conduction. Hydraulic power generation and wind power generation. Therefore, the attractive force can be utilized to generate electricity by using a suitable technical scheme. The attraction is trapped in the water mass, and the fluid water is the medium for conducting the attraction. Only when water flows, the gravitation can be circulated, and the gravitational energy can be converted into electric energy. The heave chamber discharges water with the same volume as the gravity subsidence and buoyancy rising processes. In the process of displacement, water with the same volume and mass is supplemented with the water, and the water is external force energy acting on the heaving bin. Is imposed on the gravitational energy content of the heave vessel itself. Is the acceleration of gravity. This appears to be the displacement motion of the heave chamber, in fact, the water is moving, and the gravitational force imparts the kinetic energy to the water. If the gravity potential energy of sinking of a heave cabin generates electric energy, then the compressed air is generated by the same electric energy to be drained to obtain buoyancy force for rising and resetting, and the practicability is not realized according to the law of energy conservation. The technical scheme of the invention is that two U-shaped lock-type serially-connected heaving bins move up and down simultaneously, twice equivalent gravitational potential energies are added, and the conservation energy of once compressed air is subtracted, so that the positive and net electric energy can be obtained.

Disclosure of Invention

A U-shaped lock type series connection heaving cabin power generation device in water comprises the following specific contents:

a group of steel rope pulley blocks which are respectively arranged at two sides and are connected with a U-shaped lock type series connection left and right heave cabins to do vertical up-and-down reciprocating motion are built in a water body and on a vertical horizontal plane. Two pairs of four primary and secondary pulleys are fixedly arranged on a platform on the horizontal plane, and a pair of two pulleys are fixedly arranged on the water bottom. The left and right heave bins are arranged between the secondary pulleys and the underwater pulleys, and a group of three pairs of six pulleys and the heave bins above and below form up-and-down reciprocating motion. The center bearings of the six pulleys are respectively connected with a rotor bearing of a generator. The water surface platform is provided with an electric power storage device and an air compressor which are used for conveying compressed air to the water bottom through a pipeline. The rising and sinking bin on the water surface is filled with water to obtain gravity sinking, and the water injection does not need energy. Compressed air is injected into the heave cabin under the water bottom, is discharged and inflated to obtain buoyancy force to rise, and the compressed air consumes energy. The gravitational potential energy of the sinking gravity and the gravitational potential energy of the rising buoyancy are combined to pull the rotor shafts of the generators on the water surface and the underwater platform to generate power. The key of the reciprocating up-and-down motion of the heave cabin is that the heave cabin is filled with compressed air, drained and inflated to obtain buoyancy. Only one injection of sufficient compressed air is required for each up-and-down movement.

Considering the load of pulling six rotor shafts when the gravity subsidence and buoyancy rise of the heaving cabin are taken into consideration, the elastic catching device of the rotor shaft bearing is designed. The three generator rotor shafts and the pulley bearings on one side of each heave bin which sinks by gravity are designed to be clasped to capture and pull the rotor shafts, and the three generator rotor shafts and the pulley bearings on the other side of each heave bin which rises by buoyancy are designed to be loosened to idle.

Considering that the generator stops rotating because the up-and-down reciprocating motion cannot be continuous due to the delay refractory period of each time of air charging, water discharging, air exhausting and water injecting of the heave cabin, two underwater U-shaped lock type series-connection heave cabin power generation devices are designed and are arranged as a double-generator set. The two single reciprocating motions are staggered up and down in motion time, one single reciprocating pause is used for inflating and injecting water, and the other single reciprocating pause keeps moving and acts on a rotor shaft of the generator. The reciprocating up-and-down movement is not stopped, and the generator does not stop.

Considering that the two single reciprocating heave cabins move up and down, if acting on the same generator rotor shaft, the generator can rotate in the forward and reverse directions continuously. Therefore, two generators in each group are designed to be not arranged side by side, but two rotor shafts are oppositely arranged, reciprocating heave bin pulleys are connected with opposite generator shafts, and heave bins of double reciprocating generator sets are connected with opposite generator shafts, so that the generator sets can rotate towards the same direction without stopping.

The heave silo is designed to be olive-shaped in view of reducing the water resistance of gravity subsidence and buoyancy rising. The lower tip part is internally provided with a sealed waterproof motor, so that the center of gravity is arranged below. The water and gas containing space in the middle of the vertical cylinder is a vertical cylinder, a rectangular fixed vertical plate with the same radius width and a rotating fan plate with the same size and moving around the circle center are arranged in the vertical cylinder, and one section of arc surface of the vertical cylinder is designed to be a drainage (underwater) water inlet and exhaust (water surface) door and is controlled by a hydraulic pump arm. The upper tip part is also a space for water and air. The outer side of the lower tip part is provided with an inflation tube, and a one-way air valve is arranged in the inflation tube.

The resultant force of the input compressed air and the motor acts on the built-in fan plate to rotate clockwise for inflation and drainage. The air compressor of the water surface platform continuously produces compressed air, and the compressed air is input through a pipeline and filled in a compressed air cabinet at the water bottom, so that the air pressure is greater than (at least equal to) the water pressure of the water bottom. The refractory period of inflation and drainage is shortened as much as possible. The longer the vertical height movement distance of the heave cabin is, the longer the time is, the faster the water injection and exhaust process of the water surface heave cabin and the gas injection and water discharge process of the water bottom heave cabin are, and the adjustment of the refractory period time is more favorable.

An automatic control system. The aeration and exhaust, water drainage and injection, water drainage and the opening and closing of an exhaust port of the heave cabin are controlled by a pressure switch arranged on a pressure rail through the forward and backward movement of a single fan plate according to the movement sequence; the wheel bearing and the generator rotor shaft are combined to control the catching, and an automatic catching system is comprehensively designed according to factors such as refractory period time, elevation length, power of an air compressor, power load of a generator and the like; the air charging pipe of the heave cabin sinks to the bell mouth of the compressed air cabinet due to gravity to be charged, and the pressure induction control system is used for locking the air charging pipe and releasing the air charging pipe.

Firstly, the gravitational potential energy power generation problem of the underwater U-shaped lock type series connection heaving cabin power generation device is calculated by way of example. Supposing that the heave chamber is cylindrical olive-shaped and is filled with 1m of water³. If the problem of the specific gravity of the manufacturing material of the heave cabin is solved, the heave cabin full of water has the same specific gravity with the water, and cannot sink. Suppose that a 500kg gravity block, such as a motor for draining water, is added to the lower center of gravity of the heave chamber. The heave cabin freely falls in water to obtain gravitational potential energy of gravitational acceleration to vertically sink, and a generator shaft on the water surface is pulled, so that the gravity potential energy can be used forThe gravitational potential energy power generation can be realized. The rising and sinking bin sinks by gravity, and energy does not need to be input. Let us assume a sinking stroke of 100 m. According to a gravitational potential energy calculation formula: EP ═ MGH. In the formula: EP is gravitational potential energy in joules j; m is mass, unit is kg; g is the gravitational acceleration constant 9.8; h is the stroke height in meters. The gravitational potential energy EP obtained by the heave silo sinking 100m is 500 × 9.8 × 100 ═ 490,000 joules. Joule is the unit of heat energy, converted with electricity: one degree electricity 1KWH 3,600,000 joules j. 490,000/3,600,000 is 0.1361KWH degree of electricity. Therefore, the volume is 1m³The heave cabin with 500kg gravity blocks added in water sinks for 100m to obtain the gravitational potential energy of 490,000 joules, which is converted into 0.131 degree electricity. Theoretically, the sinking stroke of the sinking bin can be infinitely long, the gravitational potential energy generating capacity is in direct proportion to the sinking stroke until the seabed is touched, and in the design of the invention, the compressed air output port is touched. Newton's third law of mechanics: the acting force is equal to the reacting force, and the process is suitable for energy conservation. Because the movement of the heave cabin is the free falling body movement under the action of the gravitation, the process is also applicable to the law of universal gravitation and the second law of Newton mechanics.

Second, 1m inside the heave chamber³Water, in 100m deep water, needs to be input by 1m³The water is discharged by the compressed air of 1 MPa, so that the buoyancy rise can be obtained. According to the public data of the air compressor manufacture, 1 MPa and 15KW air compressor can produce 1.3m in 1 minute³The air is compressed, and the electric energy is consumed by about 0.12 degree. Here, the power consumption for producing compressed air + the power consumption of the friction process is the amount of power generated by the gravitational potential energy sinking 100 m. Although the gravitational potential energy generation amount is proportional to the sinking stroke, the energy consumption for producing compressed air is also proportional, because the compressed air of 2 and 3 MPa is required for water drainage of water depths of 200m and 300m … …, the energy consumption is also increased by multiple times, and the energy conservation law is applied. However, in the technical scheme of the invention design, the two heave bins are connected in series to reciprocate up and down, one heave and one fall, and are pulled by applying force to each other, and the gravitational potential energy is added. Compressed air is injected for drainage, so that the primary heave stroke is started, and if the energy consumption of the primary compressed air and the gravitational potential energy of the heave cabin sinking are manufactured for power generationThe quantities are balanced, and the electricity generation quantity of the buoyancy ascending strokes of 200m and 300m … … of the other side of the heaving cabin is also increased by 0.52 and 0.78 … … degrees. The gravitational potential energy power generation with rising buoyancy is the positive net power generation quantity. On the contrary, if the power consumption of the compressed air counteracts the buoyancy power generation amount, the gravitational potential energy power generation amount of the sinking of the heaving cabin is the positive net power generation amount.

Thirdly, 1m is a principle of displacement based on buoyancy³After the water in the heave chamber was emptied, 1000kg of buoyancy was achieved. After the 500kg weight of the pressing cabin of the heave cabin is counteracted, the 500kg buoyancy of the heave cabin is equal to the sinking gravity. The buoyancy is from the water pressure that gravitation (gravity) produced, acts on the whole body of the heaving cabin on all sides, the bottom pressure is greater than the upper portion, so, buoyancy promotes the heaving cabin to rise vertically, produce the gravitational potential energy too, apply EP ═ MGH's formula too. Because the vertical reciprocating motion of the two heave bins simultaneously occurs in series, the gravitational potential energy and the generating capacity are added in two phases, but only the power consumption of once compressed air is consumed. Therefore, the positive net power generation amount can be generated by the invention. In the technical scheme of the invention, a double-reciprocating series generator set is designed. In order to avoid the opposite directions of the up-and-down motion of the two heave bins on the generator shaft, the invention designs that the two generator shafts of the water surface generator set are oppositely arranged, and each serially connected heave bin respectively acts on different generator shafts to ensure that the rotation directions of the two generator shafts are consistent. In this case, one generator set has two generators and four heave bins. Theoretically, according to the design of a heave stroke of 100m, the power generation amount of one minute (based on one cubic of compressed air produced in one minute) is 0.26 degrees after the power consumption is offset.

The invention aims to generate electricity by utilizing the gravity (gravity) of the nature. The existence of universal gravitation is the inexhaustible natural energy in nature. The attractive force can be utilized as long as the applicable technical solution is available. The power generation amount of gravity sinking, the power generation amount of buoyancy rising and the power consumption amount of buoyancy rising are equal to the positive net power generation amount. In the technical scheme of the invention, each generator set is independent, and N generator sets can be installed on one underwater power station. Assuming that there are 50 generator sets, each generator set generates 0.26 degrees/minute, operates at full load for 24 hours at full time, and generates 0.26 × 60 × 24 × 365 × 50 × 6,832,800 degrees of electricity. With 3,000 degrees of electricity generated by one ton of standard coal, 2,278 tons of standard coal can be saved. With 2,7 tons of carbon dioxide emitted for one ton of standard coal used for power generation, 6,150 tons of carbon dioxide will be reduced.
