Description

Buoyancy power generation system
Technical Field
The invention relates to the field of buoyancy power generation, in particular to a buoyancy power generation system.
Background
The buoyancy power equipment is an important component of a buoyancy power generation system, namely equipment for doing work outwards by utilizing kinetic energy generated by floating of compressed air in water. For example: the float bowl of the buoyancy power equipment floats upwards to generate kinetic energy after being filled with compressed air, and the float bowl is used as a driving device to drive transmission devices including a rotating bracket, a power transmission shaft and the like to do work outwards.
Under the unchangeable condition of temperature, gaseous aquatic from certain degree of depth come the floating, and the pressure that gaseous received water diminishes at the gaseous in-process that constantly floats gradually, and the gas expansion volume increases, and buoyancy also increases simultaneously, to this kind of physical phenomenon, in traditional buoyancy power generation system technical scheme, adopts and reserves gas expansion space or elasticity gasbag to come the gas after the make full use of inflation.
The pressure is 1m of 50.60125bar 3 On the compressed airFloat to the water surface, how much total work is brought by the buoyancy generated by the compressed air that can be utilized in the process under the condition of constant gas temperature?
In the first scheme, the density is 1150kg/m under the condition of 1 standard atmospheric pressure =101.325kpa =1.01325bar 3 In the saline water, the pressure containing atmospheric pressure at the depth of 440 m under the water is 50.60125bar, which is 1m at the depth 3 The pressure of the compressed air is 50.60125bar, the liquid pressure of the gas is correspondingly reduced along with the upward floating of the gas, the volume of the gas is continuously expanded, and the pressure at the depth of 440 m is 1m of 50.60125bar 3 Compressed air floats to the depth of 1m from the water surface, and the volume of the compressed air is expanded to 44.94094m 3 Table 5 shows the pressure values at 1m intervals of the gas during the flotation and the volume of the gas after expansion according to the flotation formula F Floating body ＝ρgV Row board In the formula, rho =1150kg/m 3 ，g＝9.8N/kg，V Row board ＝1731.91111m 3 ，V Row board Is the gas volume m of Table 5 3 And (5) accumulating all numerical values under columns.
F Floating body = ρ gV =1150 × 9.8 × 1731.91111 ≈ 19518638N (rounded to an integer)
Pressure is 1m of 50.60125bar 3 The total work of compressing air, floating 440 meters upwards to the water surface is:
formula W in terms of work General (1) = FS, where F =19518638n, s =1 meter
W General (1) ＝19518638×1＝19518638J
Second, the density was 1150kg/m at 1 atm =101.325kpa =1.01325bar with constant gas temperature 3 In saline water, 1m deep under water 20m 3 The pressure of the compressed air contained in the compressed air is 3.26725bar, the pressure of the compressed air at the depth is 3.26725bar, the liquid pressure of the gas is correspondingly reduced along with the upward floating of the gas, the gas volume is continuously expanded, and the pressure at the depth of 20 meters is 1m of 3.26725bar 3 Compressing air, floating to the depth of 1m from the water surface, the compressed air is expanded to 2.90177m 3 Table 1 illustrates thisThe gas in the floating process is at the depth of every 1 meter, the pressure value at the depth and the expanded gas volume are according to the buoyancy formula F Floating body ＝ρgV Row board In the formula, rho =1150kg/m 3 ，g＝9.8N/kg，V Row board ＝32.85659m 3 ，V Row board Is the gas volume m of Table 1 3 Accumulation of all values under column.
F Floating body =9gV =1150 × 9.8 × 32.85659 ≈ 370294N (rounded to integers)
Pressure is 1m of 3.26725bar 3 The total work of compressing air, floating 20 meters to the water surface is:
formula W in terms of work General assembly = FS, where F =370294n, s =1m
W General (1) ＝370294×1＝370294J
According to the gas formula P 1 V 1 ＝P 2 V 2 1m of 50.60125bar pressure 3 Conversion of the gas into the volume of gas of the same mass pressure 3.26725bar, P 1 ＝50.60125bar，V 1 ＝1m 3 ，P 2 ＝3.26725bar
V 2 ＝50.60125×1÷3.26725＝15.48741m 3
1m of pressure 3.26725bar 3 The compressed air floats to the total work 370294J contained in the water surface, and then the pressure is 15.48741m of 3.26725bar 3 The compressed air floats to the total work contained in the water surface,
W general assembly =370294 × 15.48741 ≈ 5734895J (rounded to integers)
Comparing the two schemes, the first scheme is 1m of 50.60125bar 3 The compressed air floats to the water surface from the water depth of 440 meters to obtain the total work 19518638J, and the second scheme is to apply the pressure of 1m of 50.60125bar 3 The pressure of the compressed air is converted into 3.26725bar with the same mass 3 15.48741m of 3 The compressed air floats to the water surface from the water depth of 20 meters, and the total work 5734895J is obtained. Although both schemes use the same mass of compressed air, the total work obtained with the first scheme is three times that obtained with the second scheme.
Why will the total work obtained have such a large gap? There are two reasons for this estimate:
the first aspect is the effect of atmospheric pressure, the pressure to which the gas in the liquid is subjected being the sum of the liquid pressure and the atmospheric pressure delivered by the liquid, we specify 1 standard atmospheric pressure =101.325kpa =1.01325bar, at a density of 1150kg/m 3 In the saline water, under the condition of not including atmospheric pressure, the liquid pressure of the gas at 20m under the water is 2.254bar, the liquid pressure of the gas at 440 m under the water is 49.588bar, and the pressure of 49.588bar is 1m of 49.588bar 3 Conversion of the gas to a volume of gas of 2.254bar pressure of the same mass, 49.588 ÷ 2.254=22m 3 . Under the conditions of atmospheric pressure and liquid pressure, the liquid pressure of the gas at 20 meters underwater is 3.26725bar, the liquid pressure of the gas at 440 meters underwater is 50.60125bar, and the pressure is 50.60125bar which is 1m 3 The gas is converted into the volume of the gas with the same mass of pressure 3.26725bar, 50.60125X 1 ÷ 3.26725=15.48741m 3 Therefore, the pressure added to the atmospheric pressure causes a reduction in the converted gas volume of 22 to 15.48741=6.51259m 3 。
In the second aspect, the total work contained in the gas floating to the water surface at a certain depth under the condition of constant temperature is the total work contained in the gas with the same mass floating to the water surface at a depth position above the certain depth. Stated differently, the total work gained by the second scheme is contained within the magnitude of the total work gained by the first scheme. For example, 1m of 50.60125bar of the first embodiment 3 The compressed gas floats up from the depth of 440 meters, and when the gas floats up to 20 meters from the water surface, the 1m 3 The compressed gas of (2) is expanded to 3.26725bar,15.48741m 3 Gas, and this 3.26725bar,15.48741m 3 Exactly equal to the data volume of the second variant, the first variant 50.60125bar is 1m 3 The work contained in the compressed gas from 440 meters to the gas floating height of 420 meters away from the water surface is more than that of the second scheme. We can therefore conclude that: under the condition of constant temperature, the same mass of compressed gas is deeper from the water surfaceThe higher the total work it contains.

Tables 2, 3, 4 and 5 provide data of the amount of change in the volume of gas per 1m floating of 1 cubic meter of compressed air at depths of 60 m, 110 m, 220 m and 440 m, respectively, and table 6 is a table comparing data of the total work of floating of compressed air at different depths calculated from the data of tables 1 to 5.
The data for more equal mass compressed air floats at different depths can be thought of by the more common data listed in table 6: in the buoyancy power generation system, the buoyancy power equipment with higher working height is used for processing the compressed air with the same quality under deeper water, so that more total work can be obtained, more useful work can be obtained, and the power generation capacity can be greatly increased.
One patent application No.: CN201110056486 discloses a buoyancy engine, namely a buoyancy power device, wherein a buoy makes circular motion around a rotor shaft, compressed air enters the buoy at a low position, the buoy moves upwards under the action of gas buoyancy, the buoy floats upwards to a high position to discharge the compressed air, the buoy then makes circular motion, and the buoy enters the compressed air again when the buoy descends to the low position, and the process is performed circularly. The buoy is used as a driving device to drive transmission devices such as the radial paddles and the rotor shaft to do work outwards in the circumferential motion. When the buoyancy power device increases the working height to match a deeper working depth to seek a mass of compressed air to obtain more total work, it is found that as the diameter of the buoyancy power device increases, the length of the rise trajectory of the pontoon increases, the total amount of compressed air contained in the rise trajectory is limited, so that the amount of gas charged by a single pontoon per rise trajectory is limited, and the system efficiency decreases. The following reasons for this limitation are illustrated:
positioning 0 degree in the direction of 6 points of the buoy running track of the initial air source buoyancy power equipment with the circumferential track, clockwise running a buoy to 0 degree around the axis of the power transmission shaft, counting the number of buoys which are equidistantly distributed in the ascending track at the same time by using the buoy and calculating the sum of the air volumes in the buoys, so as to calculate the total buoyancy at the moment, checking a table 7, and calculating the initial air source volume under 50.60125 atmospheric pressures: 216m 3 Instead of using 6 x 6=216m buoy volumes with 6m length for initial air source buoyancy power plant with a circumferential travel path having a working height of 440 m 3 Can meet the requirement, but must take the expansion degree of the gas floating upward into consideration, and the pressure at the depth of 440 meters is 1m of 50.60125bar 3 Compressed air, floating to the depth of 1m from the water surface, expanding the volume of the compressed air to 44.94094m 3 Then the volume of the buoy is 44.94094m 3 The expanded gas can be filled, and the volume of the buoy is 45m after an integer is taken 3 216m at 50.60125 atmospheres 3 The volume of the float bowl is determined to be 216 x 45=9720m 3 Where we use pontoons, then the length of the pontoon is 21.34 meters, look-up table 7, the initial circumferential path length of the aero-buoyancy power plant 1381.6 meters with a circumferential travel path of 440 meters working height, where there are 44 pontoons in the circumferential travel path, then 22 pontoons filled with compressed air are arranged in the ascending path, and the volume of a single pontoon is 9720m 3 See Table 7 for liquid density 1150kg/m 3 The total volume of the gas which can generate buoyancy by the buoys with ascending tracks is 10970m 3 In 2012, the largest crawler crane in China is XGC88000 of a creep group, the maximum hoisting weight reaches 4000 tons and the maximum hoisting moment 8800 is obtained when the arm length is 60 meters and the operation amplitude is 14 meters0 ton meter. When the arm length is 120 meters and the working amplitude is 18 meters, the maximum hoisting weight reaches 2020 tons, and when the working amplitude is 102 meters, the maximum hoisting weight reaches 560 tons. At present, the largest crawler crane in China is a triple-station SCC98000TM crawler crane, and the largest hoisting weight reaches 4500 tons and the largest hoisting moment reaches 98000 tons in 2021 after the crawler crane is successfully off-line in 10 months and 28 months. In 9 years, the maximum hoisting weight of the crawler crane is increased by only 500 tons, the maximum hoisting moment is increased by only 10000 tons and a small-value lifting represents advanced technology and technological progress of engineering machinery. Looking at table 7, it can be seen that the sum of the moments generated by the buoyancy of the buoys on the ascent trajectory is about 1979264 tons, which is much more than the maximum lifting moment 88000 tons of the XGC88000 of the creep group, which is about 22 times more than the maximum lifting moment 88000 tons. The possibility of manufacturing larger cranes is limited by engineering materials and technical limitations, which also affect the manufacture of the buoyancy power plant. We will turn each air intake of each buoy from 216m 3 By a factor of 22 to about 10m 3 This is done so that the moment sum generated by the buoyancy of the lift trajectory approaches 88000 tonnes, but the small amount of intake air is significantly out of tune with respect to the large volume of the buoy 3 The air inflow of each buoy is only about 10m when 22 working heights of 440 meters are built 3 What concept is? Arranged transversely for 9.6 km. At present, buoyancy power equipment with the working height of 440 meters is not seen, and whether the buoyancy power equipment can be built and operated smoothly or not is questioned.

The exhaust port 122 of the ring metal 1 and the intake port 31 of the float 3 are preferably connected and communicated through an elastic communication pipe 33, and the elastic communication pipe 33 can reduce the influence of the radial runout and the swing of the float 3 on the sealing effect of the rotationally symmetrical surface 11 of the ring metal 1 and the covering surface 21 of the covering metal 2 during operation.

When the adjusting device operates, the gear adjusting rod 62 is rotated clockwise or counterclockwise, the gear of the gear adjusting rod 62 drives the rack of the baffle 61 to move, and then the baffle is driven to do arc motion around the axis of the power transmission shaft, and the length of the opening of the air inlet slot 22 can be adjusted by the baffle 61 moving clockwise or counterclockwise. The longer the length of the baffle plate 61 covering the opening of the intake slot 22 is, the shorter the opening length of the intake slot 22 is, and conversely, the longer the opening length is. The left gear adjusting rod 62 and the right gear adjusting rod 62 respectively drive the left baffle 61 and the right baffle 61 to move, when one ends of the left baffle 61 and the right baffle 61 are in close contact, the opening of the air inlet slot 22 is completely closed, and the maximum value of the opening length of the air inlet slot 22 is the length of the air inlet slot 22, so that the length of the air inlet slot 22 is kept redundant as much as possible during design, and the opening length of the air inlet slot 22 can be shortened through an adjusting device during operation. The adjusting device can also adjust the opening position of the air inlet slotted hole 22, when a floating barrel 3 of the buoyancy power equipment is in a static state, the floating barrel 3 is firstly determined to rotate clockwise or anticlockwise, the floating barrel 3 is selected to rotate clockwise around the axis of a power transmission shaft 5, the ascending rotation track and the descending rotation track selected by the floating barrel can be determined after the selection direction is selected, when the floating barrel rotates clockwise, the ascending rotation track is arranged on the left side, the descending rotation track is arranged on the right side, the right gear adjusting rod 62 on the right side is rotated to drive the right baffle plate 61 to move clockwise and completely shield the opening of the air inlet slotted hole 22 on the descending rotation track part, the left gear adjusting rod 62 is rotated to drive the left baffle plate 61 to move clockwise to reduce shielding of the opening of the air inlet slotted hole 22 on the ascending rotation track part, air source is communicated, compressed air completely enters the floating barrel on the left ascending rotation track of the floating barrel, the floating barrel rotates clockwise, and the adjusting device adjusts the opening length and the opening position of the air inlet slotted hole 22 to the actual working requirement later.
When the device is started, the baffle 61 can be adjusted to completely seal the opening of the slotted hole 22 on the ascending track, compressed air can only enter the buoy 3 on the ascending track, and after the buoy 3 drives the whole device to rotate in a set direction, the baffle 61 is adjusted to enable the length of the opening of the slotted hole 22 to be the required length, so that the device is favorable for starting.
Three air inlet switches work synchronously, and two working modes are provided, namely a first working mode, wherein two air inlet switches respectively control an air inlet channel of one buoy 3, when the buoyancy power device 8 is started, a baffle plate 61 of the air inlet switches completely seals an opening of a groove hole 22 of a rising track, compressed air only can enter the buoy 3 of the rising track, and after the buoy 3 drives the whole device to rotate in a set direction, the baffle plate 61 is adjusted to enable the length of the opening of the groove hole 22 to be as long as required. The air inlet 221 of the covering metal 2 of the rest air inlet switch is not communicated with the air source and keeps a water-passing state, the air inlet switch controls a water drainage channel of the buoy 3, the air outlet 122 of the annular metal 1 of the air inlet switch is communicated with the water drainage port 32 of the buoy 3 in a sealing connection mode, the covering metal 2 of the air inlet switch is provided with a water inlet and air outlet slot hole 23, if the covering metal 2 of the air inlet switch is not provided with the water inlet and air outlet slot hole 23, the covering surface 21 of the covering metal 2 of the air inlet switch only needs to cover a section of the rotationally symmetrical surface 11 of the annular metal 1, the rotationally symmetrical surface 11 of the annular metal 1 corresponds to a section of the rotational track which is from the axial center of the power transmission shaft 5 to the position when the air inlet 121 begins to drain water until the position when the air inlet 121 rotates to the position when the air inlet begins to drain water, and air, and the buoy 3 can normally feed water and exhaust. In operation, when the air inlets 121 of the two air inlet switches communicated with the air source are communicated with the air outlets 222, the float bowl 3 starts to intake air and is not communicated with the air source, the air inlets 121 of the air inlet switches and the air outlets 222 which are kept in a water-communicating state are also synchronously communicated, water of the float bowl 3 starts to be discharged, the air inlets 121 of the annular metal 1 of the three air inlet switches are driven to rotate along with the rotation of the float bowl, the air inlets 121 of the two air inlet switches communicated with the air source are covered by the covering surface 21 during the rotation, air intake is stopped and simultaneously not communicated with the air source, the air inlets 121 of the air inlet switches which are kept in the water-communicating state are also covered by the covering surface 21 during the rotation, the float bowl 3 also enters more than 50% of the designed volume of the float bowl 3 during the air intake, the float bowl rotates, the air outlets 32 of the float bowl 3 are not communicated with the air source, the air outlets 122 of the air inlet switches which are kept in the water-communicating state are hermetically connected and communicated, at the air inlet slots 121 of the float bowl 3 are continuously communicated with the air inlet slots 23 of the air inlet switches, and the air inlet slots 3 are continuously rotated, and then the float bowl 3 is rotated again. In the first situation, when the float bowl 3 is operated upwards after the intake of air is finished, because the air inlets 121 of the three air inlet switches are covered by the respective covering surfaces 21, the two air inlets 31 and the water outlet 32 of the float bowl 3 are sealed, the float bowl 3 is sealed, and the expansion of the compressed air is limited, so that the first mode can increase the utilization rate of the volume of the float bowl and is suitable for the condition that the expansion degree of the compressed air is small in the process from the time the compressed air enters the float bowl 3 to the time the compressed air is discharged from the float bowl 3.
The second approach, as shown in fig. 3, is somewhat different from the first approach. The air inlet amount of the buoy 3 is controlled to be 5-50% of the volume of the buoy 3, meanwhile, the buoy 3 also comprises a water outlet 32 which always enables the inside of the buoy 3 to be communicated with the outside, namely, the buoy 3 comprises 2 water outlets 32, the water outlets 32 which are more than the first mode are not controlled by an air inlet switch, the water outlets 32 always enable the inside of the buoy 3 to be communicated with the outside, and when compressed air enters the buoy 3 and is exhausted from the buoy 3, the expansion degree of the compressed air is higher, the water outlets 32 which are not sealed can enable the expansion of the compressed air inside the buoy 3 to be unlimited, so that the utilization rate of the compressed air is increased. The second approach, while reducing the availability of the volume of the buoy 3, increases the availability of compressed air in expansion.

The buoyancy power equipment is an important component of a buoyancy power generation system, namely equipment for doing work outwards by utilizing kinetic energy generated by floating of compressed air in water. The operation of the buoyancy power device is described as an example: compressed air enters a floating drum of the buoyancy power equipment at a low position, the floating drum generates buoyancy and makes circular motion around the axis of a power transmission shaft, the floating drum upwards moves to a high position to discharge the compressed air, then the floating drum continuously makes circular motion to return to a low point to enter the compressed air again, the process is circulated all the time, and the moving floating drum is used as a driving device to drive transmission devices such as a motion support, the power transmission shaft and the like to move and do work outwards. The buoy, the motion bracket, the power transmission shaft and the like are components of the buoyancy power equipment.
The initial air source buoyancy power equipment is buoyancy power equipment which directly uses compressed air discharged by a compressor as an air source.
The circulating exhaust gas refers to the compressed air which is discharged by the buoyancy power device and is still in the liquid.
The circulating waste gas source buoyancy power equipment is buoyancy power equipment using circulating waste gas as a gas source, the inlet pressure of the circulating waste gas source is from the liquid pressure borne by compressed air of the circulating waste gas source, and the circulating waste gas source belongs to a low inlet pressure difference gas source.
The opening gas collection container is a container with a downward opening and an upward bottom, an exhaust port is arranged at the upward bottom of the container, the opening gas collection container is used for collecting compressed air discharged by an air compressor or buoyancy power equipment, the compressed air is used as an air source of the buoyancy power equipment, the air inlet pressure provided by the opening gas collection container is derived from the water pressure at the opening of the opening gas collection container, the difference between the water pressure at the opening of the opening gas collection container and the pressure at the air inlet of the float bowl is the air inlet pressure difference, and the air inlet pressure of the air source is higher as the height of the gas contained in the opening gas collection container is higher.
The buoyancy power equipment has two air inlet modes, one mode is that an air outlet of an air compressor is hermetically connected and communicated with an air inlet of the buoyancy power equipment, and the air compressor provides high air inlet pressure so as to generate high air inlet pressure difference. This kind of mode can make buoyancy power equipment's inlet channel pipe diameter do for a short time, avoids equipment volume increase, and the shortcoming is: in order to avoid large air pressure fluctuation, a high-pressure air storage tank is required to stabilize the air inlet pressure. In addition, the gas discharged by the compressor is stored by the open gas collecting container or the circulating waste gas discharged by the buoyancy power equipment is collected and stored to be used as a gas source for the buoyancy power equipment, so that a high-pressure gas storage tank can be omitted, but the pipe diameter of a gas inlet channel needs to be increased, the manufacturing difficulty of the equipment is increased, and the buoyancy power equipment suitable for low gas inlet pressure difference needs to be matched for use. The buoyancy power equipment requiring high air inlet pressure difference is difficult to use the circulating waste gas in the open air collecting container as an air source under the condition of not increasing the pipe diameter of an air inlet channel, and the buoyancy power equipment with low air inlet pressure difference can use the high air inlet pressure difference air provided by an air compressor for air inlet and can also use the circulating waste gas with low air inlet pressure difference in the open air collecting container as the air source.
We used the same working depth for comparison, see table 7:
after patent inquiry, a plurality of buoyancy power generation technical schemes are found, but the plurality of schemes can not normally operate, and a good technical scheme can not be easily found out, and the technical scheme is firstly seen, namely a patent application number mentioned in the prior art: CN201110056486, the buoyancy power machine in that patent is a buoyancy power device, the buoyancy power machine directly uses the compressed air discharged by an air compressor as an air source, so the buoyancy power machine is an initial air source buoyancy power device, the technology of the patent selects an initial air source buoyancy power device with the working height of 440 meters under the working depth of 440 meters, about 22 buoys are distributed on the rising track, and according to the characteristic that the compressed air can be expanded continuously in the rising process, each buoy is selected to be filled with 10m of air each time 3 The compressed air will accumulate a moment of about 8800 tonnes on the lifting track, which corresponds to the maximum crane moment in the world of 2012 88000 tonnes, and a maximum capacity of 9720m per pontoon 3 This results in limited volumetric utilization of the individual buoys and reduced efficiency. Xu Gong XGC88000 heavy main arm is 120 meters in length, the operation range is 102 meters, the whole machine weight is about 5500 tons, and the diameter of the buoyancy power equipment is 440 meters far beyond Xu Gong crane, so the equipment is huge in size, huge in whole machine weight and difficult to hoist, whether the initial air source buoyancy power equipment can be normally constructed and operated is questionable, and the equipment is not suitable for being used in series, because a single piece of equipment already provides huge torque, the equipment is not suitable for being used in series, and the occupied area of the equipment arranged in parallel is greatly increased.

The technical scheme of the invention is that a plurality of layers of buoyancy power equipment layers which are arranged up and down are arranged, the buoyancy power equipment layers are arranged from the deepest part of the working depth to the water surface, the number of the layers of the buoyancy power equipment layers and the number of the buoyancy power equipment on each layer are arranged according to the working depth, the height of the buoyancy power equipment and the volume of compressed gas at different depths, and an open gas collecting container is arranged between the buoyancy power equipment layers. We now choose a working depth of 440 meters, and each buoyancy power plant in this example is 39 meters at working height, 3 meters at buoy width, and 27m at buoy capacity 3 The circulating exhaust gas source buoyancy power device must be a buoyancy power device suitable for low intake pressure difference, with the actual height of the buoyancy power device being 42 meters. Arranging a first layer which is an initial air source buoyancy power device layer at the depth of 440 meters, arranging 1 initial air source buoyancy power device in the layer, arranging a second layer which is a circulating waste gas source buoyancy power device layer above the first layer at an interval of 2 meters, arranging 2 circulating waste gas source buoyancy power devices in the layer, and arranging a first opening gas collection container between the first layer and the second layer; then a third layer is arranged above the second layer at an interval of 2 meters, and is also a circulating exhaust gas source buoyancy power equipment layer, 3 circulating exhaust gas source buoyancy power equipment layers are arranged in the third layer, and then a second opening gas collection container is arranged between the second layer and the third layer; then, a fourth layer is arranged above the third layer at an interval of 2 meters and is also a circulating exhaust gas source buoyancy power equipment layer, 3 circulating exhaust gas source buoyancy power equipment layers are arranged in the fourth layer, and then a second opening gas collection container is arranged between the third layer and the fourth layer; a fifth layer is arranged above the fourth layer at an interval of 2 meters and is also a circulating exhaust gas source buoyancy power device layer, 4 circulating exhaust gas source buoyancy power devices are arranged in the fifth layer, and a second open gas collecting container is arranged between the fourth layer and the fifth layer; then a sixth layer is arranged above the fifth layer at an interval of 2 meters and is also a buoyancy power device layer of a circulating exhaust gas source,4 circulating exhaust gas source buoyancy power devices are arranged in the layer, and then a second open gas collection container is arranged between the fifth layer and the sixth layer; then, a seventh layer is arranged above the sixth layer at an interval of 2 meters and is also a circulating exhaust gas source buoyancy power device layer, 6 circulating exhaust gas source buoyancy power devices are arranged in the seventh layer, and then a second open gas collection container is arranged between the sixth layer and the seventh layer; then, an eighth layer is arranged above the seventh layer at an interval of 2 meters and is also a circulating exhaust gas source buoyancy power equipment layer, 9 circulating exhaust gas source buoyancy power equipment layers are arranged in the eighth layer, and then a second opening gas collection container is arranged between the seventh layer and the eighth layer; then, a ninth layer is arranged above the eighth layer at an interval of 2 meters and is also a circulating exhaust gas source buoyancy power device layer, 15 circulating exhaust gas source buoyancy power devices are arranged in the ninth layer, and then a second open gas collection container is arranged between the eighth layer and the ninth layer; then, a tenth layer is arranged above the ninth layer at an interval of 2 meters and is also a circulating exhaust gas source buoyancy power device layer, 60 circulating exhaust gas source buoyancy power devices are arranged in the tenth layer, and then a second open gas collection container is arranged between the ninth layer and the tenth layer; the buoyancy power equipment with the larger number of the single layer like the tenth layer can be arranged in parallel or in coaxial series according to requirements, and is flexible and changeable. Although the height of the buoyancy power devices added from the first layer to the tenth layer is consistent, the air inflow of the buoyancy power devices is not consistent, and the air inflow and the air outflow of the buoys are inconsistent, so that the rotation speeds of the buoys are inconsistent, and the air inflow and air outflow frequencies of the buoys are inconsistent. In order to make the air intake and exhaust frequencies of the buoyancy power devices of all the floors consistent, the air intake and exhaust frequencies of the buoyancy power devices of all the floors can be controlled to be consistent by adjusting the excitation magnitude of the generator. The total height from the first layer to the tenth layer is just 440 meters, the initial origin buoyancy power device of the first layer is filled with compressed gas discharged by a compressor, the initial origin buoyancy power device discharges the compressed gas after operation, the compressed gas becomes circulating waste gas, the circulating waste gas is collected by an opening gas collecting container and is supplied to the circulating gas source buoyancy power device of the next upper layer for use, the circulating waste gas discharged after the operation of the circulating gas source buoyancy power device of the layer is still in water, and the circulating waste gas is collected by the opening gas collecting container again and is supplied to the circulating gas source buoyancy power device of the next upper layer for useThe buoyancy power equipment is provided for the circulating gas source of the next upper layer, the circulation is continued until the water surface, and the depth of each layer is different, so that the table 5 is checked, the expansion degree of the gas after rising from the depth of 440 meters is inquired, the gas volume of the circulating waste gas is calculated, then the number of buoyancy power equipment is determined according to the gas volume, and the working efficiency of the technical scheme of the patent is shown as follows: the first layer of initial air source buoyancy power equipment layer at the depth of 440 meters is provided with initial air source buoyancy power equipment with the working height of 39 meters, the circumference of the diameter of 39 meters is 122.46 meters, 30 buoys are uniformly distributed on the circumference, and the volume of each buoy is 27m 3 The width of each buoy and the spacing distance between the buoys are 122.46 m/30 =4.08 m, the running speed of the buoy circumference is 3 m/s, the buoy runs 3m × 60 s/min =180 m, the number of buoys which can be inflated in one minute is 180 m/4.08 m =44.12, the air intake of the initial air source of each buoy is 40% of the volume of the buoy and is 27m 3 ×40％＝10.8m 3 Then the amount of compressed air consumed per minute is 10.8m 3 ×44.12＝476.5m 3 。
The two technical solutions are compared as follows: the technical proposal consumes 476.5m per minute 3 Compressed air, whereas the solution mentioned in the background consumes 57.3m per minute 3 Compressed air, 476.5m 3 ÷57.3m 3 =8.32, so the quantity of compressed air consumed per minute in the present technical solution is 8.32 times the quantity of compressed air consumed per minute in the technical solution mentioned in the background art, that is, the working efficiency of the present technical solution is 8.32 times the efficiency of the technical solution mentioned in the background art, and therefore the present technical solution provides a high-efficiency buoyancy power generation system adapted to a high working depth. The actual heights of the initial air source buoyancy power equipment and the circulating exhaust gas source buoyancy power equipment used in the technical scheme are both 42 meters, and those skilled in the art can think that the heights of the buoyancy power equipment can also be different heights such as 20 meters, 30 meters, 50 meters, 60 meters and the like according to the actual production requirements, and compared with the working height of the initial air source buoyancy power equipment of the technical scheme mentioned in the background art, the working height of the initial air source buoyancy power equipment of the technical scheme is 440 metersThe buoyancy power generation system of the technical scheme is convenient to hoist. The technical scheme can also connect buoyancy power equipment in parallel or in series, so that the installation mode and the operation mode are more flexible and changeable.
The invention relates to an improvement of a buoyancy power generation system, wherein a third-opening gas collecting container is arranged below an initial gas source buoyancy power device layer, an opening of the third-opening gas collecting container faces downwards, the third-opening gas collecting container stores compressed gas discharged by an air compressor and provides gas for initial gas source buoyancy power devices in an upper initial gas source buoyancy power device layer, a shell of the third-opening gas collecting container is provided with at least one gas outlet, and the gas outlet of the third-opening gas collecting container is fixedly connected with a gas inlet of the initial gas source buoyancy power devices in the upper initial gas source buoyancy power device layer in a sealing manner.
Because the initial air source buoyancy power equipment needs a large amount of compressed air, a high-pressure air storage tank is usually arranged between the compressor and the initial air source buoyancy power equipment and used for stabilizing air inlet pressure and reducing idle running of the air compressor to have an energy-saving effect. Compared with a high-pressure gas storage tank, the third-opening gas collection container is simple in structure, but the third-opening gas collection container does not provide high gas inlet pressure, so that the third-opening gas collection container is required to be matched with buoyancy power equipment suitable for low gas inlet pressure difference to be used together.

The operation process of the first embodiment is as follows: the floating cylinder 3 rotates clockwise around the axis of the power transmission shaft 5, in the embodiment, the electric motors 67 of all the buoyancy power devices 8 drive the gear adjusting rods 62 to drive the baffle plates 61 to close the openings of the air inlet slot holes 22 at the descending running track of the floating cylinder 3, so that the compressed air can only enter the floating cylinder 3 at the ascending track, the compressed air discharged by the air compressor 500 enters the first layer of buoyancy power device layer 8A, namely the floating cylinder 3 of the initial air source buoyancy power device 801 in the initial air source buoyancy power device layer 80 through the high-pressure air storage tank 530 and the air pipe 540, meanwhile, the gas pipe branch 541 also inputs a large amount of compressed air into the first open gas collecting container 91, since the compressed air input exceeds the gas demand of the buoyant power unit 8 at the level, and the amount of compressed air in the first open gas collecting container 91 exceeds the pre-designed compressed air volume, at this time, the compressed air overflows the air overflow port 97 of the first open air collecting container 91, the compressed air is discharged to the inside of the next upper second open air collecting container 92 through the air overflow pipe 98 hermetically connected and communicated with the air overflow port 97, when the amount of compressed air in the second open air collecting container 92 exceeds the pre-designed compressed air volume, the compressed air is also discharged from the air overflow pipe 98 which is hermetically connected and communicated with the air overflow port 97 of the second open air collecting container 92 to the interior of the immediately adjacent second open air collecting container 92, and in the same way, until all the open air collecting containers 9 in the system are filled with the compressed air with the required volume, thus, the air inlet pressure of the open air collecting container 9 is built, at this time, the air inlet of the air pipe branch pipe 541 is stopped, and the air pipe 540 provides the required compressed air according to the air consumption of the buoy 3 of the initial air source buoyancy power equipment 801; the first point of operation of the first embodiment is to adjust the operating speed of the buoys 3 of the buoyancy power devices 8, all the buoyancy power devices 8 of the first embodiment are of the same specification, the air inlet pressure difference is consistent, but the volumes of the compressed air after expansion are different due to the inconsistent heights of the buoyancy power devices 8, so that the air inlet amount of the buoys 3 at each layer is different, the generated torques are different, the possible rotating speeds are different, generators with different sizes and specifications are selected by calculating the torques during early-stage design, and the operating speed of the buoys 3 of the buoyancy power equipment 8 is controlled by adjusting the excitation size of the generator 510 during system operation, so that the operating speed of the buoys 3 on each layer tends to be consistent; the second point is to adjust the air intake amount of the float 3, the initial air source buoyancy power device 801 can adjust the air intake amount of the float 3 by adjusting the air intake pressure through the air compressor, and the air intake pressure of the circulating exhaust buoyancy power device 811 comes from the open air collecting container 9, so it is difficult to adjust the air intake amount of the float 3 by adjusting the air intake pressure, but the electric motor 67 can drive the gear adjusting rod 62 and then drive the baffle 61 to control the opening length of the air intake slot 22 to adjust the air intake amount of the float 3. Under the condition that the running speeds of the buoys 3 are consistent, the longer the opening length of the air inlet slot 22 is, the more the air inlet amount of the buoys 3 is, and the less the air inlet amount is. After the inlet pressure of the open gas collecting container 9 is established, the motor 67 of the buoyancy power device 8 on each layer drives the gear adjusting rod 62 to further drive the baffle 61 to adjust the opening length and the opening position of the inlet slot 22 until the requirement of the inlet air amount of the buoys 3 of the buoyancy power devices 8 on each layer is met, and meanwhile, the rotating speed of the buoys 3 of the buoyancy power devices 8 on different layers is controlled to be consistent by adjusting the excitation size of the generator. When the inlet pressure of the open gas collecting container 9 is established; when the rotation speed of the buoy 3 of the buoyancy power device 8 is stabilized; when the air input of the buoy 3 of the buoyancy power device 8 at each layer is consistent with the expanded volume when the initial air source floats to the layer, and the air compressor 500 stably and continuously provides compressed air to the initial air source buoyancy power device 801 in the first layer of buoyancy power device layer 8A, all the buoyancy power devices 8 in the embodiment can stably operate and drive the speed-up gear box 520 to further drive the generator 510 to output electric power.
It will be appreciated by those skilled in the art that the working depth can be implemented by the working principle of the present technical solution, whether the working depth is 600 meters, 800 meters or more.
The embodiment with the working depth of 440 meters, 600 meters, 800 meters or higher can be implemented in the sea with high depth, and the fixing bracket 40 of the embodiment is fixedly connected with an offshore fixing platform or a floating offshore platform. Such as a manually constructed sink, the mounting bracket 40 is attached to the edge or bottom of the sink.
Example two
As shown in fig. 7, the second embodiment is an improved first embodiment, which is a technical scheme of adding a third open gas collecting container to a buoyancy power generation system with a working depth of 440 meters. In the second embodiment, a third open gas collecting container 93 is arranged below the initial gas source buoyancy power device layer 80, an opening 95 of the third open gas collecting container 93 faces downward, the third open gas collecting container 93 stores compressed gas discharged by the air compressor 500 and supplies gas to the initial gas source buoyancy power device 801 in the upper initial gas source buoyancy power device layer 80, at least one gas outlet 96 is arranged on a shell of the third open gas collecting container 93, and the gas outlet 96 of the third open gas collecting container 93 is fixedly connected with the gas inlet 221 of the initial gas source buoyancy power device 801 in the upper initial gas source buoyancy power device layer 80 in a sealing manner. The difference between the second modified embodiment and the first modified embodiment is as follows: in the second embodiment, the gas pipe branch 541 and the high-pressure gas storage tank 530 are eliminated on the basis of the first embodiment, and since the intake pressure of the initial air source buoyancy power device 801 is from the third opening gas collection container 93, the intake pressure difference is less than 5 standard atmospheric pressure, which belongs to the low intake pressure difference, the intake speed is far less than the intake speed when the air compressor 500 of the first embodiment provides high intake pressure difference, so that the initial air source buoyancy power devices 801 and 2 are added to increase the intake speed, and the two buoys 3 of the two buoyancy power devices 8 are charged to 10.8m in total 3 When the system initially operates, the air compressor 500 directly discharges the compressed air into the third open air collecting container 93, the quantity of the discharged compressed air is far more than the air inlet demand of the buoy 3 of the initial air source buoyancy power device 801, and after the quantity of the compressed air exceeds the designed volume of the third open air collecting container 93, the compressed air can flow from the third open air collecting container 93, the overflowed compressed air is discharged into the first open air collecting container 91 immediately above through the overflowed air pipe 98, when the compressed air exceeds the volume of the first open air collecting container 91, the compressed air overflows from the overflowed air port 97 of the first open air collecting container 91, the overflowed compressed air is discharged into the second open air collecting container 92 immediately above through the overflowed air pipe 98 until the pre-designed volume of all the open air collecting containers 9 in the system is filled with the compressed air, the intake pressure of the open air collecting containers is completely established, and the air supply amount of the compressed air is reduced by the air compressor 500 to be equal to the amount of the compressed air consumed by the float bowl 3 of the initial air source buoyancy power device 801. The other structures, operation modes and principles in the second embodiment are the same as those in the first embodiment.
