Background technique

Energy is a problem that is widely concerned around the world. With the increasing demand for energy and the large-scale exploitation of oil, coal and natural gas, the energy resources stored on the earth are increasingly depleted. Finding new ways to obtain energy has become an important mission for energy scientists worldwide.

At present, energy sources other than petroleum, coal, and natural gas extraction are mainly derived from solar energy use, nuclear energy use, and water resources use.

The use of solar energy on the ground is often susceptible to changes in cloudy and sunny weather. Its utilization efficiency is low and investment is relatively large. Installing solar energy collection devices outside the atmosphere through spacecraft can avoid the effects of clouds, but energy Transmission is very difficult and the investment scale is huge, so solar energy has never been able to enter large-scale applications.

Control of nuclear reactions and conversion of reaction energy into electrical energy Although it can avoid the exploitation of a large number of resources and has high energy production efficiency, the safety control of nuclear reactions is very complicated and costly. Once a nuclear leak accident occurs, the harm to nature and humans is Inestimable, at the same time, nuclear reaction materials are also extremely rare resources on Earth. The utilization of water resources mainly includes hydropower generation and tidal power generation. It is currently a relatively good way to obtain energy. It generates electricity by utilizing the potential energy drop and tidal surge energy naturally formed by nature to generate electricity. It is a pollution-free and inexhaustible natural resource. However, hydropower generation is affected by regions and geographical locations. Dams, reservoirs, or intercepting rivers have huge project scale and construction investment, and the cost of daily maintenance is relatively large. Tidal power also has regional restrictions. It cannot be implemented in inland areas, and it is also affected by the tide and flood cycle. . In addition, wind power generation, although the construction investment is relatively small, is also limited by the terrain and area, and even the wind power generation equipment installed at the valley wind outlet will also affect its normal power generation capacity due to the change in the size of the wind.

In summary, although human beings have made great progress in the acquisition of natural non-exploitable energy, there are still many deficiencies and shortcomings, so that people continue to understand in the process of continuously seeking ways to use natural resources. Explore the unrecognized phenomena of natural energy in order to obtain further use of natural energy. In fact, many natural phenomena may contain more or less natural energy. The rational and ingenious development and utilization of these energies will be able to provide human society with endless and pollution-free huge energy, which is also the goal of energy scientists to strive for it.

Summary of the invention

The main purpose of the present invention is to provide a potential energy lifting device based on atmospheric pressure by utilizing the atmospheric pressure phenomenon shown in the Torrie disassembly experiment. The phenomenon that the atmospheric pressure lifts the liquid and the buoyancy principle of the liquid raises the potential energy of an object having a specific gravity smaller than that of the liquid through the container. '' Another object of the present invention is to provide a potential energy power generation device for the above-mentioned shortcomings and deficiencies in the use of natural resources. The power generation device uses the potential energy boosting device based on the atmospheric pressure to perform potential energy to electrical energy of the object. Energy conversion. The object of the present invention is achieved by the following technical solutions:

An object potential energy lifting device includes a liquid pool containing a liquid, a cylindrical container, and a floating body. The bottom of the cylindrical container is open, and the top is provided with an upper closed gate. The specific gravity of the floating body is less than the specific gravity of the liquid and greater than the specific gravity of the air. The cylindrical container is erected on the liquid pool, and its bottom end is located below the liquid surface, and a lower closed gate is provided in the middle part. The distance between the position of the lower closed gate and the liquid surface of the cylindrical container is not less than the maximum size of the floating body . The upper closed gate is provided with an air suction nozzle which is connected with an external vacuum pump and used for sucking out air in the cylindrical container. When the pressure of the air in the cylindrical container is negative pressure, the liquid enters the cylindrical container at a height that makes the pressure of the liquid on the liquid surface of the liquid pool equal to the atmospheric pressure. The liquid pool is provided with a solid structure which enables the floating body to fall into After the liquid pool, a lateral displacement guide groove is generated. The outlet of the guide groove is located below the bottom end of the cylindrical container, and the inlet is located where the floating body falls into the liquid pool.

After completing the installation and setting of each component in the above technical solution, the external vacuum pump evacuates the interior of the cylindrical container (lower the air pressure as much as possible). At this time, the upper closed gate is closed and the lower closed gate is opened. In the process that the air pressure in the cylindrical container gradually reaches the vacuum, the liquid in the liquid tank enters the cylindrical container and rises to a certain height under the effect of external atmospheric pressure. This height is just the liquid-to-liquid entering the cylindrical container. The height reached when the pressure value of the tank surface is equal to the atmospheric pressure value.

After the evacuation operation is completed, the entire device enters the initial working state. At the beginning of work, the floating body is poured into the liquid pool from above the liquid surface. When the floating body is put into the liquid pool, its height from the liquid surface is at least such that the depth of the floating body sinking after entering the liquid pool is greater than the height of the floating body itself. The floating body is placed in the liquid pool at the inlet end of the guide groove. Because the floating body sinks inertia after entering the liquid, in this process, the guide groove moves the floating body toward the bottom end of the cylindrical container opening. Under the action of water resistance and buoyancy, the sinking speed of the floating body reaches 0. After that, the floating body also moved below the bottom end of the cylindrical container at the same time, and then floated. The trajectory of the floating body in the liquid pool is approximately V-shaped. When the floating body reaches the bottom of the cylindrical container, it immediately enters the cylindrical container until the liquid level in the cylindrical container is highest. In this process, after the floating body passes the lower closed gate in the cylindrical container, the lower closed gate is closed. When the float reaches the top of the cylindrical container (at the liquid level), the upper closed gate opens. Because the liquid in the cylindrical container is blocked after the lower closed gate is closed, the liquid in the cylindrical container will not flow back into the liquid pool after the upper closed gate is opened. Take the floating body from the top of the cylindrical container from the upper closed gate and move it to the outside of the cylindrical container, and align it with the position where the floating body initially falls into the liquid pool. At this time, because the height of the floating body from the liquid surface is greater than the release height when it initially falls into the liquid pool, the potential energy of the floating body is higher than that at the initial position when it falls into the liquid pool.

In the above process, the potential energy of the floating body actually comes from the lifting effect of the liquid in the cylindrical container, that is, the potential energy of the floating body can be improved by the buoyancy of the liquid. For example, when the liquid is water, the specific gravity of the floating body is 0.8 times that of water, and the air pressure in the cylindrical container is close to 0, the height of the liquid surface is about 10 meters. When the floating body is initially released, its height from the surface of the pool is 1 meter. When the float is in a cylindrical container W 200

After rising by the buoyancy of water in the medium, the potential energy obtained by it greatly exceeds the potential energy when it is in the initial release position. '

The above phenomenon can be explained in principle based on the laws of gravity, Archimedes' law, and the atmospheric pressure experimental phenomenon of Torricelli.

As we all know, in the famous Torricelli experiment, the height of the mercury column at a standard atmospheric pressure is 76 cm. The formula for calculating the pressure is:

P = p -g-H

among them, ? = Atmospheric pressure

P = liquid density

g = gravitational acceleration

11 = liquid height

In the above test, if mercury was replaced with water, the height of the water column was calculated as 10.337 meters according to the above formula.

If a static object with a specific gravity smaller than that of water is placed at the bottom of the water column, according to Archimedes's law, the object will float upward along the water column and reach the top of the water column. At this time, the potential energy of the object is increased. If the object is translated out of the top of the water column and the object is released, the object will fall freely under the action of universal gravitation and convert the potential energy into kinetic energy. Through specific experiments, it can be found that when the object returns to the initial state position at the bottom of the water column again, the object has higher energy. If this energy is effectively converted, the natural energy contained in atmospheric pressure can be continuously output, creating a new energy source. „

Based on the above technical solution of the atmospheric pressure potential energy lifting device, a power generation device can be manufactured, which includes a transmission mechanism and a generator whose input end is connected to the output end of the transmission mechanism, and also includes a potential energy-kinetic energy conversion device.

The potential energy-kinetic energy conversion device is composed of more than one extension arm, a rotating shaft, and a bracket.

The bottom ends of all extension arms are evenly distributed and fixed on the rotating shaft, and the top ends extend radially outward along the rotating shaft to form a windmill-shaped rotating body. The top of each extension arm is provided with a floating body receiving portion. When the windmill When the rotating body stops rotating, a floating body receiving portion is always located just outside the top of the cylindrical container in the potential energy lifting device. The rotation shaft is mounted on the bracket and is connected with the rotation input end of the transmission mechanism.

When the floating body is taken out from the top of the cylindrical container in the potential energy lifting device from the upper closed gate and moved to the release position where the floating body falls into the liquid pool, the floating body receiving part installed on the potential energy-kinetic energy conversion device is just below the floating body After the buoy is released, the buoy falls on the buoy receiving part. Due to gravity, the buoy pushes down the extension arm and drives the pinwheel-shaped rotating body to rotate as a whole. When the buoy receiving part rotates to the minimum position, the buoy is separated from the buoy receiving part and falls again. Into the liquid pool.

When the floating body drives the pinwheel-like rotating body, the upper closed gate is closed again, and the lower closed gate is reopened. Because the floating body occupies a certain volume, and after opening the upper closed gate, a small amount of air enters the cylindrical container. The top level is inside, so when the floating body leaves, the liquid level in the cylindrical container drops. At this time, the vacuum pump is started to extract excess air from the top of the cylindrical container, and the liquid level returns to the initial position.

In addition, the rotation of the pinwheel-shaped rotating body causes the generator to rotate by the drive mechanism, thereby generating electric energy.

When the extension arm supporting the floating body rotates downward, another extension arm located above the extension arm rotates toward the top of the cylindrical container. When the floating body leaves the supporting part and starts to fall freely, another floating body supporting part installed on another extending arm adjacent to the extending arm stays just below the position where the floating body is released. During this process, the positions of all components return to the initial working state.

After the buoyant body detached from the receiving part of the buoyant body falls into the liquid pool again, the entire equipment repeats the above-mentioned operation process. Thus, the buoyant body will continuously fall into the liquid pool and float again and again, thereby driving the windmill-like rotating body to rotate and converting the potential energy of the buoyant body. For electrical energy.

Since the rotation of the windmill-shaped rotating body is intermittent during the operation of the above-mentioned equipment, in order to continuously rotate the generator, an energy storage component can be installed in the transmission mechanism to continuously rotate the output rotating shaft, thereby achieving the purpose of generating electricity. It is also possible to use a plurality of potential energy lifting devices, so that the release of each floating body is set in chronological order. At the same time, the rotating shaft is lengthened and a plurality of pinwheel-shaped rotating bodies are correspondingly installed to drive the rotating shaft of the potential energy-kinetic energy conversion device to rotate continuously. Provide uninterrupted kinetic energy for generators. When the floating body floats, its potential energy is much larger than its initial potential energy when it falls into the liquid pool. After the potential energy-kinetic energy conversion device of the floating body is operated, its potential energy is converted into electrical energy by the potential energy-kinetic energy conversion device. The electrical energy is greater than the energy consumption of the upper and lower closed gates, vacuum pumps, floating body lifters and other components during operation. Therefore, The invention is capable of continuously supplying electrical energy to the outside.

As we all know, due to the gravity of the earth itself, the atmosphere covering the earth's surface has atmospheric pressure, and this pressure will always exist with the existence of the earth. The power of atmospheric pressure will be inexhaustible. It can be seen from the above technical solution that the present invention makes clever use of the Torri disassembly experimental phenomenon, and uses the atmospheric pressure to create two liquid surfaces of different heights, and uses the buoyancy of the liquid to increase the potential energy of the floating body. The increased potential energy is output through the conversion device to achieve the purpose of power generation, and the output energy comes from the gravity of the earth. As long as the gravity does not disappear, this energy will never be exhausted. The invention essentially uses atmospheric pressure to extract and transform the gravitational energy of the earth, and provides a new natural resource utilization path for human beings that can be used for a long time without any pollution.

Hereinafter, the present invention will be further described in detail through specific embodiments and drawings.

According to the phenomenon of Torri disassembly experiment, a specific embodiment of the potential energy lifting device of the object according to the present invention can be made, and its structure principle is shown in FIG. 1.

This embodiment includes a pool 1 containing water, a cylindrical container 2 and a floating body 3. Among them, the cylindrical capacity The device 2 has an open bottom end surface, and an upper closed gate 21 is provided on the top end surface. The cylindrical container 2 is erected on the pool 1 with its bottom end surface located below the water surface. When the upper airtight gate 21 is closed, the top of the cylindrical container 2 is hermetically closed by a sealing measure. An exhaust nozzle 211 is provided on the surface of the upper closed gate, and the exhaust nozzle 211 is connected to the external vacuum pump 6 through the negative pressure tank 5. A solenoid valve 51 is also connected in series between the negative pressure tank 5 and the suction nozzle 211.

The cylindrical container 2 is further provided with a lower closed gate 22 that can block water in the cylindrical container 1, and the lower closed gate 22 is disposed at the lower half of the cylindrical container '2.

The specific gravity of the floating body 3 is Q. 9. A wireless signal transmitter 31 is mounted on the floating body 3.

A guide groove 11 capable of lateral displacement of the floating body 3 after falling into the pool 1 is also fixed in the pool 1. The guide groove 11 is an arc-shaped pipe body, and the outlet end thereof is located below the open end of the cylindrical container 2. The entrance end is located where the floating body 3 falls into the pool. Around the ring at the bottom end of the cylindrical container 1, the ring is provided with a downwardly-shaped conical introduction port 25, and the opening of the conical introduction port 25 is exactly aligned with the exit end of the guide groove 11.

A platform 23 is horizontally fixed outside the top end of the cylindrical container 2. The upper closed gate 21 is provided on the surface of the platform 23 through a sliding pair. At the same time, the upper closed gate 21 is also provided with an upper closed gate driving motor 212 for driving the upper closed gate 21 to open or close.

On the surface of the upper closed gate 21, a lifting frame 21 3 for lifting the floating body 3 out of the cylindrical container 2 is also provided. The lifting frame 213 is provided with a hoist and a cable. At one end of the cable, a grip capable of automatically closing / opening is installed. Hook 21 31.

The lower closed gate 22 is also installed on a lower platform 24, and a lower closed gate drive motor 221 is installed on the lower platform 24 (the drive motor can also be directly installed on the surface of the outer extension of the lower closed gate 22). '

In addition, an upper wireless signal receiver 15 and a lower wireless signal receiver 14 are also installed at the upper and lower closed gates 21 and 22.

After the vacuum pump 6 of this embodiment evacuates the inside of the cylindrical container 2, water enters the cylindrical container 2 to form a water column. At a standard atmospheric pressure, the height of the water column is about 10 meters. Floating body 3 After putting into the pool 1 at point B in the figure, under the action of inertia, the floating body 3 continues to sink, and the inclined side wall of the guide groove 11 laterally displaces the floating body 3 to the open bottom end of the cylindrical container 2. Due to the buoyancy and resistance of water, the floating body 3 gradually stops sinking and rises. Guided by the conical inlet 25, the floating body 3 enters the cylindrical container 2 and starts to float upward. When passing through the lower closed gate 22, the lower wireless signal receiver 14 receives the signal from the wireless signal transmitter 31 installed on the floating body 3, and the signal is transmitted to the external signal processing device 9, which is installed on the external signal processing device 9 The lower closed gate driving motor 221 on the lower platform 24 drives the lower closed gate 22 to close, and blocks water in the cylindrical container 2. When the floating body 3 rises near the top, the upper wireless signal receiver 15 receives the signal from the wireless signal transmitter 31, and the signal is also transmitted to the external signal processing device 9, which is installed on the upper closed gate 21 The upper closed gate driving motor 212 on the surface drives the opening of the upper closed gate 21, and at the same time, the lifting frame 213 on the surface of the upper closed gate 21 starts to operate. The cable is lowered and the grapple 2131 is fastened to the floating body 3. The hoisting machine rotates, The floating body 3 is lifted. After the floating body 3 is lifted out of the cylindrical container 2, the upper wireless signal receiver 15 cannot receive the signal from the wireless signal transmitter 31, and the external signal processing device 9 closes the upper closed gate 21, and at the same time, the lower closed gate 22 is in the external signal. Under the control of the processing device 9, it is automatically turned on. Since the floating body 3 discharges water of the same volume in the cylindrical container 2, and since the upper closed gate 21 is opened, part of the air enters the top of the cylindrical container 2, so when the upper closed gate 21 is closed, the lower After the closed gate 22 is opened, the water level in the cylindrical container 2 drops. Therefore, the solenoid valve 51 under the control of the external signal processing device 9 is opened. After the negative pressure tank 5 quickly evacuates a small amount of air in the cylindrical container 2, The solenoid valve 51 is closed. With the closing of the upper closed gate 21, the floating body 3 of the raised cylindrical container 2 is moved to point A in the figure.

After the floating body 3 is released at point A, under the action of universal gravitation, it passes through point B in a free-falling state and falls back into the pool 1, and its falling position is exactly where the floating body 3 initially falls into the pool. After the buoyant body 3 falls into the pool 1 again, under the action of buoyancy, the buoyant body 3 re-enters the cylindrical container 2, the upper closed gate 21 and the lower closed gate 22 repeat the first opening or closing state, so that the floating body 3 returns to A point.

In this embodiment, the structure of the floating body lifter is shown in FIG. 2. In the figure, the upper closed gate 21 slides through After the movable pair slides away on the surface of the platform 23, the grapple 2131 descends to fasten the top of the floating body 3, and to facilitate the fastening of the floating body 3, a groove may be provided on the top surface of the floating body 3.

FIG. 3 is a schematic structural diagram of a floating body. In this embodiment, the shape of the floating body 3 is a flat elliptical streamline, and the inside thereof is a hollow body, which is filled with a specific gravity adjusting liquid 32, and the specific gravity value of the floating body 3 can be achieved by the specific gravity adjustment, so that the floating body 3 Runs smoothly. To facilitate controlling the attitude of the floating body 3 during operation, when manufacturing the floating body 3, the density of the lower end 33 is greater than that of the upper end 34 of the floating body 3, so that the floating body 3 can always maintain the same attitude when running in water.

In this embodiment, when the upper closed gate is opened, the closed lower closed gate will keep the water levels of the separated upper and lower water columns from falling, so more effective sealing measures must be taken. When the position of the lower closed gate is below the level of the pool, its structure is shown in Figure 4. In the figure, an annular groove 221 is respectively provided on the upper and lower surfaces of the lower closed gate 22 that are in contact with the side wall of the cylindrical container 1, and the same correspondence is also provided on the corresponding section of the side wall of the cylindrical container 1.环槽 26。 The annular groove 26. The annular groove 221 coincides with the corresponding annular groove 26 when the lower closed gate 22 is closed.

A hollow inflatable seal rubber ring 7 is placed in the annular groove 221 in advance, and an inflation port 71 of the seal rubber ring 7 is provided on the side of the lower closed gate 22 and is connected to the external air compressor 8. When the lower closed gate 22 is closed, it is inflated into the sealing rubber ring 7 so that it has at least one standard atmospheric pressure. At this time, the sealing rubber ring 7 fills the annular groove 221 and the corresponding annular groove 26 so that the cylindrical container 2 is filled. Separated water will neither leak nor return to the sink.

When the position of the lower closed gate is above the water level of the pool, considering that the lower closed gate may cause outside air to enter the cylindrical container during movement, a lower closed gate with a vacuum seal is specially provided. Its structure is shown in FIG. 5. In the figure, the cylindrical container 2 is located at the lower closed gate, and a sealed tank 200 is provided. The sealed tank 200 surrounds the outer periphery of the cylindrical container 2 when the lower closed gate is opened. Up the water.

The sealed tank 200 is provided with a lower platform 24 passing through the cylindrical container 1 to separate the cylindrical container 2 into upper and lower bodies. The periphery of the lower platform 24 is fixedly connected to the inner wall of the sealed tank 200. Hermetic A lower closed gate 22 is dynamically installed, and the lower closed gate 22 is opened or closed by a driving motor 221 provided outside the sealed tank 200. When the lower closed gate 22 is closed, the external air compressor 8 inflates the sealing rubber ring 7 by sealing the inflation port 201 installed on the sealed tank 200 and relying on an inflation tube (not shown) to make the upper cylindrical container 2 The internal water does not flow out into the lower cylindrical container 2, thereby avoiding the phenomenon that the water in the cylindrical container 2 flows back into the pool.

In the above process, the potential energy of the floating body 3 at point A is greater than the initial potential energy of the floating body 3 at point B (because the velocity of the floating body 3 at the beginning of point B is 0, its kinetic energy is 0, and only the smaller (Potential energy), therefore, when the floating body 3 falls from point A and reaches point B, under the action of gravity acceleration, it not only has the same potential energy as the initial state, but also has kinetic energy.

During the operation of the floating body 3, the water in the cylindrical container 1 continuously provides potential energy to it. .

'In the above embodiment, since the floating body 3 has a potential energy at point A that is much larger than that at point B. When the floating body 3 falls, if its potential energy can be converted, it is possible to output energy to the outside.

However, since operations such as opening or closing the upper and lower closed gates and using a vacuum pump for air suction and water replenishment require energy consumption, only the energy consumed is less than the externally output energy, and the purpose of real energy output can be achieved. Therefore, the possibility can be verified by the following calculation. Potential energy when the floating body is at the top of the water column E #body

In order to facilitate theoretical calculations, the diameter of the water column is set to 0.8 m. The basic formula of Tori's profit-sharing experiment: ρ-p. G. H can calculate the water column height H = 10. 337 meters, taking the approximate height of 10 meters, the floating body is a streamlined shape with an approximate diameter of 0.6 meters, Approximate height 1.0 m.

Take floating body density of 0.9 10 ³ kg / m3

Mass of floating body: m floating body = V floating body 'd floating body = 0. 3 ² ■ π · 1 · 0. 9 «255 kg

Potential energy of the floating body: Ε Floating body = m · g · Η = 255 X 9. 8 X 10 = 24990 J The minimum potential energy required for the floating body to turn around and enter the bottom of the liquid pool E

Because the specific gravity of the floating body is close to the specific gravity of water, when the floating body uses inertia to enter the liquid pool and turn around The required minimum potential energy height is only slightly greater than the height of the floating body. For the purpose of calculation, take the minimum potential energy required for h = 1 meter: E Lowest-m floating body · g · 1 = 255 x 9. 8 = 2499 J Closed doors each consume energy W opening and closing π

Because the upper and lower closed gates are opened and closed alternately, the combined external force on the upper and lower sides of the lower closed door when the upper closed door is closed is 0, and the combined external force on the upper closed door when the closed door is closed is also 0. Just consider the weight of the door body when calculating.

The shield volume of the closed door is m dense. According to the diameter of the water column, the closed door is required to completely close the water column when it is closed. The size of the door should be larger than the diameter of the water column.

08 米。 Take the door body to have room for movement, take the door body length is 1.5 times the diameter of the water column is 1.2 meters, the width is slightly larger than the diameter of the water column is 0.9 meters, the thickness to take into account the weight of the water column, take 0.08 meters , The quality of the closed door:

m dense = V dense · d dense = 0. 0864 · d dense

The material of the door body can be selected from light alloy materials with a density of less than 2 x 10 ³ kg / m3 on the basis of considering no deformation, maintaining flatness and minimizing energy consumption.

Let d density = 2 10 ³ kg / m3

m dense = 0. 0864d dense = 172.8 kg

Since the door body moves in parallel, using modern mechanical friction theory, the friction coefficient can be made less than 0.1 after adding rolling friction. Force pushing door:

F sliding door> m dense 'g · 0.1

The actual moving distance of the door switch S-0.8 m

In a circular motion of the floating body, the upper and lower closed gates move four times, and the work done by the external force to open and close the closed gate is:

W opening and closing door = F sliding door ■ S-4

Substitute m dense = 172.8 kg, g = 9.8,

W swing door = 541. 9 J- Floating body water consumption to help raise energy W to help

When the floating body comes out of the water, because the density of the floating body itself is large, even under the action of buoyancy inertia, it can not be guaranteed to completely out of the water surface. In order to remove the floating body from the top of the water column, a lifting frame is installed on the upper closed gate. Before the lifting frame moves the floating body out of the water column, the floating body needs to be lifted to a height first. If the height value is set to 1, the energy removed is:

W assistant lift = m float g · h = 255 X 9. 8 X 1 = 2499 J Energy consumed by the suction and rehydration device W

After the floating body enters the water column, its volume of liquid must be drained. After the floating body has discharged water, the water level will drop by a height, and the volume will be filled by air. In order to ensure that the floating body can flush the water column next time, the water column must be replenished. According to the principle of the connector, as long as the air at the top of the water column is pumped out, the water level in the water column can be raised.

A vacuum pump can be used to remove the air from the top of the water column. The energy consumed by the vacuum pump is calculated as follows: When a ZJ-type Roots vacuum pump with a high vacuum efficiency is used, it is equipped with a 1.1 kW motor and pumps 70 liters per second.

Volume of floating body: V floating body = 0.3 ² · π · 1 = 283 liters

According to this data calculation, the vacuum pump is evacuated for 4 seconds, and the gas in the volume of the floating body in the water column can be basically pumped. The energy consumption is:

W pumping compensation = P · t = 1 1 00 x 4 = 4400 J

The lowest potential energy for the floating body to enter the water column by inertia is the lowest E;

The energy consumption of the moving door is W ^ n. Considering the transmission efficiency, η = 0.8

Floating body water helps boost energy consumption W

The energy consumption of pumping fluid is W ^ fluid.

The total energy consumption is _W,:

W total consumption = E minimum + W door open / closed door / η + W assisted lifting + W pumping fluid = 2449 + 541. 9/0. 8 + 2449 + 4400

= 10255. 5J

The above calculations show that the potential energy of the floating body in front of a free fall at a height of 10 meters is E floating body = 24990 joules, and the total energy consumption of a cyclic movement of the floating body for one week is W total consumption = 10 ² 55. 5 joules (in the above calculation, it is also due to This plus the energy consumption value of the sealing rubber ring in the lower closed gate. However, the inner diameter of the sealing rubber ring is different, and the energy consumed is different. Therefore, according to the actual use of the sealing rubber ring, the energy consumption is about For 100 joules). It can be known that the energy that the floating body can output to the outside is:

E floating body — E minimum -W total consumption = 24990-2499-1 0255. 5-100 = 12135. 5 (Joule) The above calculations show that the excess 121 35. 5 Joule energy can be taken out by the energy harvesting device for power generation.

If the diameter of the water column in this embodiment is increased, and the volume of the floating body is increased accordingly to increase its mass, a higher potential energy difference can be obtained, so that this embodiment has a higher power output.

After the above embodiment is combined with another potential energy-kinetic energy conversion device, a potential energy power generation device according to the present invention can be manufactured, and a specific structure thereof is shown in FIG. 6.

In FIG. 6, the potential energy-kinetic energy conversion device is installed beside the above embodiment, and it is composed of four extending arms 41, a rotating shaft 42, and a bracket 43. The bottom end of the extension arm 41 is fixed on the rotating shaft 42 and radially extends outward in the radial direction of the rotating shaft 42 to form a windmill-shaped rotating body. The rotation shaft 42 is mounted on the bracket 43 and is connected to the rotation input end of the transmission mechanism 101. A floating body receiving portion 411 is provided on the top of each extension arm 41. When the floating body 3 is moved from the top of the cylindrical container 2 to point A, one of the four floating body receiving portions 411 is located at the bottom of the floating body 3.

After the floating body 3 is released and landed on the floating body receiving portion 411, under the action of gravity, the extension arm 41 rotates in the direction of the arc arrow in the figure, and drives the rotating shaft 42 to rotate. The transmission mechanism 101 transmits the rotation to the generator 102. When the extension arm 41 reaches the point B in the figure, the floating body receiving portion 411 on the adjacent extending arm 41 above it is located just below the point A. At this time, the floating body 3 is separated from the floating body receiving portion 411. After falling into the pool 1 again, and after repeating the above-mentioned ascension and floating process, return to point A in the figure again, and start another cycle motion.

In the above-mentioned cyclic movement of the floating body 3, in the process of the floating body 3 driving the extension arm 41 to rotate, its potential energy is released and converted into kinetic energy into the transmission mechanism 101, thereby outputting the potential energy of the floating body 3 to the outside. When a mechanical energy storage component (such as a clockwork) is provided inside the transmission mechanism 101, the transmission mechanism 101 can continuously and continuously transmit kinetic energy to the generator 102, thereby causing the generator 102 to generate electricity outward. At this point, the improvement of the potential energy of the floating body 3 and the conversion of the potential energy to electrical energy have been completed.

It is worth noting that, in the above-mentioned potential energy power generation equipment, the potential energy-kinetic energy conversion device may take various forms. In order to improve the output efficiency and simplify the energy transmission process, the potential energy power generation equipment can also be made into a structure as shown in FIG. 7.

In FIG. 7, the potential energy-kinetic energy conversion device is erected on the side of the potential energy lifting device of the object, near the drop of the floating body 3, and is composed of a generator 102, a transmission chain 301, and a driven wheel 300. The transmission chain 301 loops the rotating shaft of the generator 102 and the driven wheel 300 together, and a plurality of upper hooks 302 are provided on the surface of the transmission chain 301. The distance between the generator 102 and the driven wheel 300 is equivalent to the height of the cylindrical container 2. A lower hook 35 matching the upper hook 302 is provided on the surface of the floating body 3. When the floating body 3 falls from point A, an upper hook 302 on the transmission chain 301 is located just below the lower hook 35, so that the upper hook 302 hangs the floating body 3 through the lower hook 35. Under the action of gravity, the floating body 3 drives the transmission chain 301 to rotate, and causes the generator 102 to rotate to output electric energy. When the floating body 3 reaches the point B, the upper hook 302 connected to the floating body 3 moves in the direction of the driven wheel 300 and disengages from the lower hook 35. At this time, the floating body 3 falls into the pool 1 again. Repeating the above process, the cyclic operation of the floating body 3 enables the generator 102 to intermittently output energy to the outside.

Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not limiting. Although the present invention is described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technology of the present invention can be Modifications or equivalent replacements of the solutions without departing from the spirit and scope of the technical solutions of the present invention should be covered by the claims of the present invention.
