Description

Device and method for optimizing energy transfer by utilizing external force balance Technical Field

[0001] The present invention belongs to the technical field of renewable energy, and in particular relates to a device and method for optimizing energy transfer by utilizing external force balance. Background Art

[0002] Renewable energy is energy derived from nature, including solar power, wind power, geothermal energy, and tides. Tides are generated by the gravitational field, and therefore gravitational field energy is considered renewable energy. Tidal power generation indirectly utilizes gravitational field energy, but humans cannot control the timing, location, and magnitude of tides. U.S. Patent No. 8,919,111 B2, "Device and Method for Harvesting Energy from a Liquid by Utilizing Buoyancy," utilizes a physical phenomenon to convert gravitational field energy into mechanical energy. This technology can be applied at any time, location, and space, enabling controlled application of gravitational field energy and promising application prospects.

[0003] The device described in the aforementioned patent document converts Earth's gravity into mechanical energy, referred to herein as a gravity converter. The structure of the gravity converter is a hydraulic mechanism, and while it can be replicated, it can also be industrialized by improving the energy transfer structure. Within the device system, there are two distinct energy transfer subsystems: external energy and the gravitational field. External energy is converted into mechanical energy, ensuring conservation of energy transfer. Gravitational field energy is converted into work due to the liquid's gravity in the form of buoyancy. In other words, external energy is transferred in a closed loop, facilitating buoyancy transfer. Because external energy transfer is dependent on the amount of liquid input into the device, achieving higher output power requires a high liquid flow rate. Consequently, a separate, large external energy transfer device must be designed, which is not only costly but also results in significant energy losses. Another factor affecting energy conversion efficiency is friction losses caused by sealing. Therefore, optimizing energy transfer by leveraging the device's inherent structure and energy transfer characteristics—thus reducing liquid delivery costs, increasing output power, and minimizing sealing losses—is a challenge to address in the application of this technology.

At this time, the liquid sealing chamber becomes the air sealing chamber, and the air sealing chamber has the float (2) to become the liquid sealing chamber, and the device is in the initial state of the next working cycle.

[0043] Beneficial effect: In the background technology, the structure of the gravity converter belongs to hydraulic machinery. In the existing technology, to realize external energy transmission, it is necessary to design a hydraulic energy closed-loop transmission mechanism to output the energy transmitted by buoyancy. However, the essence of the background technology is that the external force provides the liquid static pressure, and the external force is converted into the liquid horizontal component force. The buoyancy is a certain liquid volume in the selected liquid under the gravity field, and the float (2) transmits the external energy and the buoyancy at the same time. Therefore, by utilizing the inherent structural characteristics of the device, the external force is balanced by pre-setting gas, and the two independent energies are transmitted in the device, thereby solving the problem of requiring an independent device to transmit external energy.

[0044] By presetting liquid and gas with a pressure of P, the input external energy is transferred within the device system through the gas delivery device and the energy compensation device, which simplifies the external energy transfer mechanism and greatly reduces the device cost and mechanical loss.

[0045] The gas delivery device uses preset gas to balance external force, making external force transmission simpler.

[0046] The energy compensation device uses system gas to drive liquid, reducing the flow of the booster pump and using potential energy such as cylinders to transport liquid. The external force is transmitted smoothly, with low cost and high output efficiency.

[0047] The dual-unit linkage system connects the energy transfer cycle, making it more suitable for the centralized operation of multiple units and improving system efficiency. The use of rolling seals instead of sliding seals optimizes the floating body process and reduces friction losses, making it particularly suitable for high-power units.

[0048] Since the present invention adopts the above-mentioned technical solution and utilizes the inherent idle structure of the device, it solves the problems of complex external energy circulation transmission structure, high cost and large energy loss in the application of background technology. It is a new technical solution suitable for the application of new technologies and achieves the purpose of the present invention. BRIEF DESCRIPTION OF THE DRAWINGS

[0083] The wall seal includes: a sealing bracket 3-2, an optical axis 3-3, a rubber shaft 3-4 and a sealing body 1-9; the sealing bracket 3-2 is sealed and fixed in the shell 1; the optical axis 3-3 and the rubber shaft 3-4 are connected between the two sealing brackets 3-2; the end faces of the optical axis 3-3 and the rubber shaft 3-4 are sealed with the sealing bracket 3-2 and can rotate on the sealing bracket 3-2; the outer circle of the optical axis 3-3 is connected to the outer circle of the rubber shaft 3-4 in a rolling sealing connection; the rubber shaft 3-4 is connected to the side and top surfaces of the float 2 in a rolling sealing connection; the optical axis 3-3 is connected to the sealing body 1-9 in a sliding sealing connection; the sealing body 1-3 is fixed on the shell 1.

[0084] The shaft seal 3-1 is an elastic seal, which includes: two sealing sleeves and a sealing strip; the sealing sleeves are connected at both ends of the sealing strip; the sealing sleeves are respectively installed on the two output shafts 2-1 on the side of the float 2, and the sealing strip is attached to the bottom surface of the output shaft 2-1; the sealing sleeves seal the output shaft 2-1 and the housing 1; the sealing strip seals the housing 1 and the axial bottom of the output shaft 2-1.

[0085] Preferably, there are four sealing brackets 3 - 2 , namely two upper sealing brackets and two lower sealing brackets; the two upper sealing brackets are installed on the top of the inner wall of the shell 1 , and the two lower sealing brackets are installed above the lower shaft seal 3 - 1 of the shell 1 .

[0086] Preferably, there are two upper sealing brackets, with two bearing chambers on the side facades and bottom surfaces of the upper sealing brackets, and the bearing chambers on the side facades of the two upper sealing brackets correspond to each other; bearings are installed in the bearing chambers, and the core shafts of the optical axis 3-3 and the rubber shaft 3-4 are connected to the inner rings of the bearings; there are two lower sealing brackets with the same structure, and there are two bearing chambers on the upward surface, and the bearing chambers correspond to the bearing chambers on the bottom surface of the upper sealing bracket.

[0087] Furthermore, the sealing body 1-9 is a bearing structure, as shown in Figure 3, the bearing and the optical axis 3-3 are dynamically fitted and sealed or elastically sealed; the sealing body 1-9 is fixed to the inner wall of the shell 1 with threads, or welded to the shell 1 as a whole.

[0088] Preferably, the optical axis 3-3 comprises a rigid cylinder or cone; core shafts extend from the center of each end of the optical axis 3-3, and the core shafts are mounted on bearings in the bearing chamber. The rubber axis 3-4 comprises a cylinder or cone. The center of the rubber axis 3-4 is a rigid cylinder, with elastic rubber applied to the surface of the rigid cylinder to form an elastic cylinder. Core shafts extend from the center of each end of the elastic cylinder, and the core shafts are mounted on bearings in the bearing chamber. The cone is used to seal the side of the float 2 to accommodate the increase in linear velocity of the side as the radius increases, compensating for slippage caused by the constant rotational speed of the cylinder.

[0089] The rubber shaft 3-4 forms a rolling seal with the side and top surfaces of the float 2, and when the float 2 rotates, the rubber shaft 3-4 is driven to rotate; the rubber shaft 3-4 and the optical shaft 3-3 generate rolling friction, driving the optical shaft 3-3 to rotate; the optical shaft 3-3 and the bearing of the sealing body 1-9 are dynamically matched and sealed; therefore, the sliding friction is converted into rolling friction, reducing the sealing resistance loss and the surface processing accuracy of the float 2.

[0090] When the side and top surfaces of the floating body 2 are coated with elastic rubber, the optical axis 3-3 is directly rolled and sealed with the floating body 2. In this case, the wall sealing structure does not include the rubber axis 3-4.

[0091] A method for optimizing energy transfer by balancing external forces: liquid is pre-placed in a water tank 6, and gas at a pressure of P is pre-placed in an airtight chamber. The pre-set gas pressure P is applied to the liquid, transporting the liquid to the liquidtight chamber. A float 2 in the liquidtight chamber rotates about an output shaft 2-1 toward the airtight chamber, compressing the pre-set gas and outputting torque from the output shaft 2-1. The compressed pre-set gas is then supplied to the water tank 6. The gas pressure P is transmitted within the device, and the external force of the gas pressure P is used to balance the static pressure of the liquid, optimizing the energy transfer structure.

[0092] The pressure P is: H / 2 ≤ P <H, where H is the inner diameter height of the shell 1 and also the liquid level height in the water tank 6 .

[0093] To better understand the operation, assume the following: the volume and height of the liquid-sealed chamber, air-sealed chamber, and water tank are equal; the volume of the gap between float 2 and shell 1 is negligible relative to the volume of float 2; water tank 6 is pre-stored with water to a height H, where H is the inner diameter of shell 1; and gas is pre-set at a pressure P within the air-sealed chamber and surge tank 5, where P = H / 2. The thrust exerted on float 2 by the pre-set gas P is equal to the horizontal thrust exerted on float 2 by the liquid level H.

[0094] There are three ways to input the liquid from the water tank 6 into the liquid sealing chamber:

[0095] 1. Directly use the booster pump 7 to deliver liquid;

[0096] 2. Using the air sealed chamber as a cylinder, the float 2 moves toward the air sealed chamber, compressing the gas in the air sealed chamber, and directly supplying the generated compressed gas to the water tank, using the compressed gas to transport liquid;

[0097] 3. The liquid input method of compressed gas + booster pump reduces the delivery load of the booster pump.

[0098] Combining the above two liquid delivery methods of direct delivery by a booster pump and delivery by compressed gas, and taking into account the system resistance loss and the potential energy change of the liquid in the water tank 6, the following liquid input method using compressed gas + booster pump is adopted.

[0099] Compressed gas + booster pump liquid delivery method:

[0100] Step 1-1: Complete the initial preparation state: open the first stop valve 1-2 of the first liquid inlet and outlet 1-1 of the liquid sealing chamber, and close the second stop valve 1-4 of the second liquid inlet and outlet 1-3 of the air sealing chamber; the gas reversing device 4 is in a state where the air sealing chamber is connected to the surge tank 5 and the liquid sealing chamber is connected to the atmosphere; inject liquid with a height H into the water tank 6 and the liquid sealing chamber, and inject gas with a pressure P into the surge tank 5 and the air sealing chamber;

[0101] Step 1-2: Start working: connect the surge tank 5 and the water tank 6. The gas pressure P in the surge tank 5 sends the liquid in the water tank 6 into the liquid sealing chamber, drives the float 2 to rotate and compresses the gas P in the air sealing chamber; the compressed gas is replenished to the surge tank 5;

[0102] Step 1-3: The float 2 in the liquid sealed chamber rotates toward the air sealed chamber around the output shaft 2-1 under the action of buoyancy and the horizontal component of the liquid force. The float 2 compresses the preset gas, which is then replenished to the water tank 6 through the surge tank 5, and torque is output from the output shaft 2-1.

[0103] Step 1-4: When the gas pressure P in the water tank 6 plus the liquid potential energy is insufficient to push the liquid into the liquid sealed chamber, the booster pump 7 starts to work and the booster pump 7 inputs the liquid in the water tank 6 into the liquid sealed chamber;

[0104] Step 1-5: When the liquid in the water tank 6 is completely input into the liquid sealing chamber, the float 2 is completely input into the air sealing chamber; the liquid in the water tank 6 is transferred into the liquid sealing chamber, and the gas with a pressure of P in the air sealing chamber is transferred into the water tank 6;

[0105] Step 1-6: The gas reversing device 4 switches the gas path, closes the air-sealed chamber, and opens the liquid-sealed chamber; at this time, the gas pressures in the liquid-sealed chamber and the water tank 6 are equal, and the liquid in the liquid-sealed chamber returns to the water tank 6 with its liquid potential energy unchanged; the liquid-sealed chamber returns to the water tank 6, and the liquid in the water tank 6 is replaced into the liquid-sealed chamber. At this time, the liquid-sealed chamber becomes the air-sealed chamber, and the air-sealed chamber becomes the liquid-sealed chamber with the float 2, and the device is in the initial state of the next working cycle.

[0106] The preset pressure P may be greater than or less than the horizontal thrust of the liquid on the float 2 according to actual working conditions.

[0107] The above working method realizes the use of gas pressure P external force to balance the static pressure of the liquid and optimizes the energy transfer structure.

[0108] Example 2: This embodiment's sealing device is based on Example 1, but uses a sliding seal instead of a rolling seal, also completing and realizing the sealing function of rolling seal 3. The sliding seal is a sealing assembly that is fixedly connected to the housing 1, and the sealing surface of the sealing assembly is in sliding sealing connection with the side and top surfaces of the float 2.

[0109] Other details are the same as in Example 1.

[0110] Example 3: This example illustrates the application of a device that optimizes energy transfer by utilizing external force balance. Specifically, it is a multi-unit coordinated external force transfer device. As can be seen from Example 1, a single gas and liquid transfer process constitutes a single operating cycle, and each cycle requires regeneration of buoyancy. Therefore, in practical applications, two or more gravity converters are typically required to operate in conjunction. In this example, an independently operating gravity converter is referred to as a single unit. Figure 4 illustrates a dual-unit coordinated energy transfer device.

[0111] The energy transfer device consisting of two units is called a dual unit. Its function is to use the working chamber of one unit to replace the water tank 6, realize the internal circulation of liquid in the unit, reduce the cost of the external energy transfer device, reduce energy loss, and improve the output efficiency of the system.

[0112] The dual-unit linkage energy transfer device also includes: two gravity converters, a water separator and a water separator controller; the two gravity converters have the same structure, namely unit A and unit B; the first air inlet and outlet 1-5 of unit A and the second air inlet and outlet 1-7 of unit B are connected to the gas reversing device 4, and the gas reversing device 4 is connected to the pressure regulating tank 5; the liquid inlet and outlet 1-1 of unit A and the second liquid inlet and outlet 1-3 of unit B are connected to the booster pump 7 through a water separator, and the water separator is connected to the water separator controller.

[0113] The water distributor, which switches the air intake and exhaust between units A and B, includes a first water distributor 8 and a second water distributor 9. The gas reversing device 4, which switches the air intake and exhaust between units A and B, can be a single integrated device or multiple independent devices. This embodiment uses two independent gas reversing devices 4.

[0114] When one of the units is used as a working unit, the other unit is used as the water tank 6 of the working unit. After a working cycle is completed, the unit that originally served as the water tank 6 is exactly the initial position of the next working unit.

[0115] When two sets of gas reversals 4 are used, the gas inlet and outlet ports 1-5 and 1-7 of unit A and the gas inlet and outlet ports 1-5 and 1-7 of unit B are each connected to a gas reversal 4; both gas reversals 4 are connected to the pressure-surge tank 5. When two sets of water distributors are used, the inlet of booster pump 7 is connected to the outlet of first water distributor 8, and the outlet of booster pump 7 is connected to the inlet of water distributor 9. The inlet of first water distributor 8 and the outlet of water distributor 9 are simultaneously connected to the first liquid inlet and outlet 1-1 and the second liquid inlet and outlet 1-3 of units A and B. The first water distributor 8 and the second water distributor 9 each have four valves. The water distributor controller controls the opening of two corresponding valves in the two reversing valve groups and closes the other valves in the two reversing valve groups.

[0116] A dual-unit linkage working method: as shown in Figure 4.

[0117] Step 2-1: Complete the initial preparation state: Fill the shell 1 of unit A without float 2 and the shell 1 of unit B with float 2 with liquid, and input gas with a pressure of P into the surge tank 5 and the sealed chamber of unit B without float;

[0118] Step 2-2: Lock the floats 2 of units A and B with the housing 1. The locking means preventing the floats 2 of the units and the housing 1 from moving relative to each other.

[0119] The first water distributor 8 and the second water distributor 9 work, closing the liquid inlet and outlet 1-1 of unit A and the second liquid inlet and outlet 1-3 of unit B, and opening the second liquid inlet and outlet 1-3 of unit A and the first liquid inlet and outlet 1-1 of unit B to connect with the booster pump 7;

[0120] The gas reversing device 4 of unit A is in operation, and its position is: the liquid side pipeline of unit A is connected to the surge tank 5, and the non-liquid side of unit A is connected to the atmosphere. The gas reversing device 4 of unit B is in operation, and its position is: the non-liquid side pipeline of unit B is connected to the surge tank 5, and the liquid side is connected to the atmosphere. Preparation is complete.

[0121] Step 2-3: Enter the first working cycle state: unlock the float 2 of unit B from the shell 1; the unlocked unit B becomes the working unit, and the working chamber of the unlocked unit A with liquid is used as a water tank;

[0122] The surge tank 5 applies gas at a pressure of P to the working chamber of unit A containing liquid. When the hydraulic energy of unit A is balanced with the liquid potential energy of unit B, the booster pump 7 starts to work and inputs the liquid in unit A into the liquid sealing chamber of unit B.

[0123] The hydraulic energy is the gas pressure P applied by the surge tank plus the liquid potential energy;

[0124] Step 2-4: The float 2 of unit B rotates toward the air sealing chamber and compresses the gas in the air sealing chamber, and the output shaft 2-1 outputs torque; a portion of the output torque is supplied to the device system for its own use;

[0125] Step 2-5: When the pressure in the air sealed chamber of unit B is greater than the pressure in the surge tank 5, the gas in the air sealed chamber flows into the surge tank 5;

[0126] Step 2-6: After the liquid in unit A completely enters the liquid sealing chamber of unit B, the working states of units A and B are switched, that is, the liquid sealing chamber of unit A becomes an air sealing chamber, and the liquid sealing chamber of unit B becomes a liquid sealing chamber;

[0127] Step 2-7: The device system completes an energy transfer cycle and is in the working state of the next energy conversion cycle;

[0128] Preparation for the second working process: Unit A is unlocked and becomes the working unit; Unit B is locked, and its liquid sealing chamber is a water tank; the energy transfer device is in the reverse working state; the first water distributor 8 and the second water distributor 9 are switched to connect the first liquid inlet and outlet 1-1 of Unit A and Unit B, and close the second liquid inlet and outlet 1-3 of Unit A and Unit B; the working state of the switching gas controller 4 is: the first air inlet and outlet 1-5 of Unit B is connected to the pressure-regulating tank 5, and the second air inlet and outlet 1-7 of Unit B is connected to the atmosphere; the second air inlet and outlet 1-7 of Unit A is connected to the pressure-regulating tank 5, and the first air inlet and outlet 1-5 is connected to the atmosphere.

[0129] Part of the shaft torque generated by buoyancy and gas pressure P is used to compensate for system energy loss and for the device system's own use, which includes controlling the system, boosting, driving the boost pump 7, replenishing gas to the pressure-surge tank 5, and replenishing liquid lost due to leakage.

[0130] Figure 5 shows a gravity converter. In this converter, the float 2 is less than a quarter of a circle, and the housing 1 is less than a half of a circle. The housing 1 is centrally positioned for operation, with the inlet and outlet located near the output shaft 2-1. The bottom of the housing 1 forms an angle of 45-60° with the horizontal plane.

[0131] The rest is the same as in Example 1.

[0132] Example 4: This example utilizes a cylinder-type energy compensation device. As shown in Figures 6 and 7 , the cylinder-type energy compensation device includes a cylinder 10 and a motor 11. The side of the housing 1 is connected to the cylinder 10, and the motor 11 is connected to the cylinder 10. Each of the two working chambers of the gravity converter has an energy compensation device, with the same installation location and operating method.

[0133] The motor 11 is a device for compensating for energy loss during the external force transmission process, and is a power frequency motor or a variable frequency motor.

[0134] The cylinder 10 is a device for conveying liquid by using the pre-set gas in the air-sealed chamber. The cylinder 10 is in the form of a plunger cylinder or a telescopic plunger cylinder.

[0135] Preferably, the main structure of the plunger cylinder is a universal plunger cylinder, as shown in Figure 6, including: a cylinder body 10-1, a plunger 10-2, an air supply port 10-3 and a drive rod 10-4; the cylinder body 10-1 is connected to the side of one side of the shell 1, and the cylinder body 10-1 is provided with an air supply port 10-3; the drive rod 10-4 is connected to the plunger 10-2 and passes through the head of the cylinder body 10-1, and a gearbox is provided on the drive rod 10-4 located outside the head, and the gearbox is connected to the motor 11.

[0136] Furthermore, preferably, the gearbox is a rack and pinion gearbox, and the gearbox is connected to the motor 11 .

[0137] Preferably, the plunger of the telescopic plunger cylinder is a telescopic plunger, as shown in Figure 7, comprising: a cylinder body 10-1, a telescopic plunger, an air supply port 10-3 and a drive rod 10-4; the cylinder body 10-1 is connected to the side of one side of the shell 1, and the cylinder body 10-1 is provided with an air supply port 10-3; the drive rod 10-4 is connected to the telescopic plunger and passes through the head of the cylinder body 10-1, and a gearbox is provided on the drive rod 10-4 located outside the head.

[0138] The telescopic plunger is located in the cylinder body 10-1, and includes: a telescopic tube, an end plate 10-5 and a slide rail 12; one port of the telescopic tube is sealedly connected to the inner wall of the cylinder body 10-1, and the other port is sealedly connected to the end plate 10-5; the inner side of the end plate 10-5 is connected to the drive rod 10-4; the edge of the end plate 10-5 is provided with a sliding sleeve, the sliding sleeve is installed on the slide rail 12, and the slide rail 12 is fixed to the inner side of the shell 1.

[0139] Furthermore, there are three slide rails 12 , which are evenly distributed in the housing 1 , two of which are fixed on the arc surface of the housing 1 , and one is fixed on the bottom surface of the housing 1 .

[0140] A cylinder-type, multi-unit, linked external force transmission device, employing the dual-unit operation of Example 3, is shown in Figure 8, which is a top view of the device with cylinders positioned on the side of a gravity converter. In the figure, the working chambers of the gravity converter with floats 2 are chambers A1 and B1, while the working chambers without floats 2 are chambers A2 and B2. The combination of a gravity converter and a cylinder-type energy compensation device is called a cylinder-type gravity converter. This example uses a single group of manifolds.

[0141] .The external force transmission device of the cylinder-type multi-unit linkage includes: a cylinder-type gravity converter, a gas reversing device 4 and a water distributor 13; there are two cylinder-type gravity converters, namely unit A and unit B, and the liquid circuits of the two cylinder-type gravity converters are connected to the water distributor 13, and the gas circuits are connected to the gas reversing device 4.

[0142] The water distributor 13 is a device that switches the liquid flow between units A and B and is connected to the liquid inlets and outlets of A1, A2, B1, and B2 respectively. When the water distributor 13 is placed in the high position, the water tank 6 becomes a pool, and the liquid level in the pool is ≥H.

[0143] The gas reversing device 4 is a device for switching the gas flow between the A unit and the B unit, and is connected to the gas delivery ports 10-3 of the A1, A2, B1, and B2 cylinders 10 respectively.

[0144] Unloading cylinder 10 involves transferring the gas within cylinder 10 to the working chamber of the cylinder requiring unloading. As shown in Figure 6, a gas exchange valve is installed at the outlet of first gas inlet and outlet port 1-5, connected to gas delivery port 10-3. During unloading, a reversing valve connects to gas delivery port 10-3, allowing the gas within cylinder 10 to enter the working chamber through the reversing valve. When cylinder 10 pushes out the liquid within the working chamber, the reversing valve switches direction, connecting the gas to the atmosphere.

[0145] The following is a working method in conjunction with FIG8 : Assume that the work done by the plunger 10 - 2 is equal to the work done by the liquid being pushed, and the work done by the liquid is equal to the work done by the compressed gas.

[0146] The water separator 13 connects the liquid inlet and outlet of chamber A2 and chamber B1, closes the liquid inlet and outlet of chamber A1 and chamber B2, the gas converter 4 connects the gas delivery port of the cylinder 10 of chamber A2 and chamber B2, and the reversing valve is connected to the atmosphere.

[0147] During operation, motor 11 drives cylinder 10, transferring the pre-set liquid in chamber A2 to chamber B1 via water distributor 13. The pre-set gas in chamber B2 is compressed by float 2 and enters the cylinder through the gas inlet of chamber A2 via gas reversing device 4. The cylinder's plunger pushes the liquid in the working chamber. The buoyancy of float 2 rotates output shaft 2-1, generating torque.

[0148] When the system is unloaded, the reversing valve is switched to connect with the gas port. Motor 11 rotates in the opposite direction, pulling the plunger back to its original position. The gas in the cylinder enters working chamber A2 through the reversing valve. Chamber A2 becomes an airtight chamber, and chamber B1 becomes a liquidtight chamber, completing the first energy transfer cycle.

[0149] Switch the water separator 13 and the gas converter 4, and the device system works in reverse, and the rest is the same as above.

[0150] When the shaft torque output by the floating body 2 is variable, a relatively stable output torque can be obtained by adjusting the gravity of the floating body 2. For example, the floating body 2 is a homogeneous body, and the gravity of the floating body 2 is 50% of the buoyancy.

[0151] Other details are the same as in Example 3.

[0152] Example 5: This example is another installation form of the energy compensation device in Example 4, as shown in Figure 9. The housing 1 is changed from the original semicircular body to a rectangular parallelepiped, and the cylinder 10 of the energy compensation device is installed on the left and right end surfaces of the rectangular parallelepiped, that is, in the radial direction, that is, in the horizontal direction in Figure 9.

[0153] Using a rectangular parallelepiped will increase the volume compared to a semicircular body. Since the liquid and gas are converted with equal potential energy (pressure) when multiple units are linked, i.e., the gas pressure acts on the plunger 10-2 and the float 2, and the liquid static pressure acts on the plunger 10-2 and the float 2, the purpose of external force transmission is not changed.

[0154] Other details are the same as in Example 4.
