Description

Technical Field

[0001] This invention relates to the field of supporting rotating equipment, and more specifically to a method and a platform that can arbitrarily change the horizontal direction of a heavy object by relying on buoyancy. Background Technology

[0002] Traditional architecture places great emphasis on orientation, generally facing south. This arrangement greatly benefits lighting and ventilation. However, in summer, good lighting becomes a disadvantage. In summer, buildings need to be positioned away from direct sunlight to reduce heat exposure. Furthermore, natural winds can change direction at any time, blowing from any direction. To optimize ventilation, houses also need to be able to turn. Once a traditional building is completed, its foundation is fixed. The house cannot change its orientation. Some buildings abroad are constructed on circular railway tracks, with train wheels mounted on them. The house is built on the train wheelset. The completed house can change its orientation at any time, but the friction between the rails and the train wheels is significant, requiring a large power source to change the house's orientation, making it inefficient. Ships and buildings on ships have similar capabilities. Ships float on water and can easily change direction, but ships are limited to lakes and rivers. Buildings on these sites are restricted to lakeshores and rivers. On land, shipyards cannot be moved freely, and lakes must be constructed.

[0003] Therefore, the current foundation of the house has the following drawbacks: 1. The foundation (ground) of the house is fixed and its orientation cannot be changed.

[0004] 2. Houses built on the wheels of trains on circular tracks can change their horizontal orientation, but they must be lightweight. Furthermore, turning requires a significant driving force, necessitates complex equipment, and results in relatively low efficiency in rotating the building.

[0005] 3. Houses based on ship hulls can change their orientation at any time, but the construction site must be on a lake or river, and cannot be built arbitrarily on land. Summary of the Invention

[0006] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a method and platform for arbitrarily changing the horizontal direction of a heavy object by means of buoyancy support. By eliminating frictional resistance through buoyancy support, the horizontal direction of the heavy object can be arbitrarily adjusted with a small driving force, while ensuring stability and safety during the rotation process.

[0007] The objective of this invention is achieved through the following technical solution: a platform that relies on buoyancy to support and arbitrarily change the horizontal orientation of a heavy object, comprising: A floating pool, located below ground level, is used to hold liquids. Several tire troughs are provided on the inner wall and bottom of the floating pool. A pontoon, the upper surface of which is used to support heavy objects, is immersed in the liquid in the pontoon pool, and the buoyancy generated by displacing the liquid supports the heavy objects being carried. A water storage tank is located outside the floating pool and is used to store liquid. The water storage tank is connected to the floating pool through a pumping and draining assembly, which is used to pump liquid into the floating pool or to extract liquid from the floating pool. The guide wheel assembly includes at least one pair of tires symmetrically arranged on both sides of the pontoon. A portion of each tire is located in the tire movement groove at the bottom of the pontoon, and the other portion of each tire extends into the pontoon and abuts against the side wall of the pontoon, applying a clamping force to the pontoon so that the pontoon is always located in the center of the pontoon and maintains a gap with the inner wall of the pontoon. The support wheel assembly includes at least one pair of tires symmetrically arranged on both sides of the pontoon, a portion of each tire being disposed within a tire movement groove at the bottom of the pontoon, and the other portion of each tire extending into the pontoon and abutting against the bottom of the pontoon; and The drive wheel assembly includes at least one pair of drive motors symmetrically arranged on the ground on both sides of the pontoon. Each drive motor is connected to a drive wheel via a drive assembly, and the drive wheel extends into the pontoon pool and drives the pontoon to rotate.

[0008] As a further technical solution, the drive wheel set includes at least one pair of tires symmetrically arranged on both sides of the pontoon. A portion of each tire is located in the tire movable groove at the top of the pontoon, and the other portion of each tire extends into the pontoon and abuts against the side wall of the pontoon, applying a clamping force to the pontoon. Each drive motor is connected through a drive assembly and drives the corresponding tire to rotate, thereby driving the pontoon to rotate.

[0009] As a further technical solution, the drive assembly includes a drive gear, a driven gear, and a transmission shaft. The drive gear is mounted on the motor shaft of the drive motor, and the drive gear meshes with the driven gear for transmission. The driven gear is sleeved on the transmission shaft, and the transmission shaft passes through the ground into the tire movement groove at the top of the floating pool, driving the corresponding tire to rotate.

[0010] As a further technical solution, leaf spring suspensions are installed on the tires corresponding to the drive wheel assembly, the guide wheel assembly, and the support wheel assembly.

[0011] As a further technical solution, the drive wheel is a drive gear, which is mounted on the motor shaft of the drive motor. At the same time, a float gear ring is set on the outer wall of the upper part of the float box. The drive gear meshes with the float gear ring for transmission, so that the drive gear directly drives the float box to rotate.

[0012] As a further technical solution, a water collection tank is also included, which is located at the lowest point of the floating pool and is used to collect the liquid in the floating pool; the pumping and drainage assembly includes a suction pump and a suction pump motor for driving the suction pump, one end of the suction pump is connected to the water storage tank through a water pipe, and the other end of the suction pump is connected to the water collection tank through a water pipe.

[0013] As a further technical solution, the outline of the floating pool matches that of the floating box, which adopts a closed box structure and has a rotating outline.

[0014] As a further technical solution, the gap between the pontoon and the inner wall of the pontoon pool is maintained at 1~2cm.

[0015] A method for arbitrarily changing the horizontal orientation of a heavy object by relying on buoyancy, using the aforementioned platform that can arbitrarily change the horizontal orientation of a heavy object by relying on buoyancy, includes the following steps: S1. Start the pumping and drainage components to pump the liquid in the water storage tank into the floating tank, so that the floating box floats under the buoyancy of the liquid. S2. Start the drive motor. The drive motor drives the float to rotate through the corresponding drive wheel. When the float rotates to the required angle, turn off the drive motor. S3. Restart the pumping and drainage components to pump the liquid in the floating pool back into the storage tank until the liquid in the floating pool is completely pumped out, the floating box is no longer buoyant, and sinks to contact the bottom of the floating pool.

[0016] The beneficial effects of this invention are as follows: 1. By utilizing the buoyancy of water to eliminate the friction between the float box and the float pool, the driving force required to rotate the heavy object is minimized; 2. Through the coordinated action of multiple sets of elastic suspension (leaf spring suspension) side wall guide wheel groups, the float box is accurately centered in the float pool, preventing side wall contact friction; 3. The bottom elastic suspension wheels convert sliding friction into rolling friction, preventing the floating box from scraping against the pool bottom due to the shift in the center of gravity during the lifting and lowering process; 4. Adding a gear ring drive method can achieve precise angle control, meeting the application scenarios with high requirements for orientation accuracy. Attached Figure Description

Detailed Implementation

[0022] The present invention will now be described in detail with reference to the accompanying drawings: Example 1: As shown in the attached document Figures 1-4 As shown, this type of platform, which relies on buoyancy to arbitrarily change the horizontal direction of a heavy object, includes a float pool 2, a float box 3, a water storage tank 11, a guide wheel assembly, a support wheel assembly, and a drive wheel assembly. Reference Appendix Figure 1 The floating pool 2 is located below the ground 1 and is used to hold liquid. Several tire movement grooves 18 are formed on the inner wall and bottom of the floating pool 2. Preferably, the tire movement grooves 18 are arranged symmetrically with respect to the floating pool 2.

[0023] Furthermore, the upper surface of the float box 3 is used to support the weight 15 (which may be a house or a car, etc.), and the float box 3 is immersed in the liquid of the float pool 2, supporting the weight 15 by the buoyancy generated by displacing the liquid.

[0024] A water storage tank 11 is located outside the floating pool 2 and is used to store liquid. The water storage tank 11 is connected to the floating pool 2 via a pumping and drainage assembly, which pumps liquid into or out of the floating pool 2. Furthermore, a collection tank 10 is included, located at the lowest point of the floating pool 2, to collect the liquid within the floating pool 2. The pumping and drainage assembly includes a suction pump 12 and a suction pump motor 13 for driving the suction pump 12. One end of the suction pump 12 is connected to the water storage tank 11 via a water pipe 14, and the other end of the suction pump 12 is connected to the collection tank 10 via a water pipe 14.

[0025] Furthermore, the guide wheel assembly includes a pair (in this embodiment, a pair, but other numbers are also possible) of tires 4 symmetrically arranged on both sides of the float 3. In the guide wheel assembly, a portion of each tire 4 is disposed within the tire movement groove 18 at the bottom of the float pool 2, and the other portion of each tire 4 extends into the float pool 2 and abuts against the side wall of the float 3. The tires 4 of the guide wheel assembly can apply a pressing force to the float 3, ensuring that the float 3 is always located at the center of the float pool 2 and maintains a gap with the inner wall of the float pool 2. Preferably, the outline of the float pool 2 matches the float 3, the float 3 adopts a closed box structure, and the outline of the float 3 is a rotating body. The gap between the float 3 and the inner wall of the float pool 2 is maintained at 1~2 cm.

[0026] The support wheel assembly includes a pair (in this embodiment, a pair, but other numbers are also possible) of tires 4 symmetrically arranged on both sides of the pontoon 3. In the support wheel assembly, a portion of each tire 4 is disposed in the tire movement groove 18 at the bottom of the pontoon 2, and the other portion of each tire 4 extends into the pontoon 2 and abuts against the bottom of the pontoon 3.

[0027] like Figure 1 , 2 As shown, the drive wheel assembly includes a pair (in this embodiment, a pair, but other numbers are also possible) of tires 4 symmetrically arranged on both sides of the float 3. In the drive wheel assembly, a portion of each tire 4 is disposed in the tire movable groove 18 at the upper part of the float pool 2, and the other portion of each tire 4 extends into the float pool 2 and abuts against the side wall of the float 3, applying a pressing force to the float 3. At the same time, a pair (in this embodiment, a pair, but other numbers are also possible) of drive motors 7 are symmetrically arranged on the ground 1 on both sides of the float. Each drive motor 7 is connected through a drive assembly and drives the corresponding tire 4 to rotate (in the drive wheel assembly), thereby driving the float 3 to rotate.

[0028] The drive assembly includes a drive gear 8, a driven gear 9, and a drive shaft 6. The drive gear 8 is mounted on the motor shaft 17 of the drive motor 7. The drive gear 8 meshes with the driven gear 9 for transmission. The driven gear 9 is sleeved on the drive shaft 6. The drive shaft 6 passes from the ground 1 into the tire movable groove 18 at the top of the floating pool 2, and drives the corresponding tire 4 in the drive wheel set to rotate through the drive shaft 6.

[0029] like Figure 1 , 2 As shown in Figure 4, leaf spring suspensions 5 are installed on the tires 4 corresponding to the drive wheel assembly, guide wheel assembly, and support wheel assembly.

[0030] Example 2: As Figure 3 As shown, the difference from Embodiment 1 is that, in cases where high rotational accuracy is required, a drive gear 8 is installed on the motor shaft 17 of each drive motor 7. At the same time, a float gear ring 16 is provided on the outer wall of the upper part of the float box 3. The drive gear 8 meshes with the float gear ring 16 for transmission, and the drive gear 8 extends into the float pool 2, so that the drive gear 8 (drive motor 7) directly drives the float box 3 to rotate.

[0031] Example 3: A method for arbitrarily changing the horizontal direction of a heavy object by relying on buoyancy, using a platform as described in Examples 1 and 2, comprising the following steps: S1. Start the pumping and drainage assembly to pump the liquid in the water storage tank 11 into the floating tank 2, so that the floating box 3 floats under the buoyancy of the liquid. S2. Start the drive motor 7. The drive motor 7 drives the float box 3 to rotate through the corresponding drive wheel. When the float box 3 rotates to the required angle, turn off the drive motor 7. S3. Restart the pumping and drainage components to pump the liquid in the floating pool 2 back into the storage tank 11 until the liquid in the floating pool 2 is completely pumped out, and the floating box 3 is no longer buoyant and sinks to contact the bottom surface of the floating pool 2.

[0032] Example 4: Refer to Appendix Figure 1 When the supported structure weighs hundreds or thousands of tons: for example, building a villa whose orientation can be changed at will. This situation can be further divided into two types: 1. Building a villa that can rotate as a whole. 2. Building a villa where parts of the building can rotate. (Designing kitchens and bathrooms, which require water supply and are inconvenient to rotate, in fixed parts. Designing other living spaces in the active parts that need to frequently change orientation). The construction of these two types of buildings can be based on... Figure 1 The proposed solution is implemented as follows. The rotating part can be built on a cylinder, with the center of gravity of the structure designed to be exactly at the center of the disc. If it is not in the center, we can set up an appropriate leveling mechanism to shift the center of gravity to the center of rotation through the lever principle. This ensures that the pontoon will not tilt when it floats. Firstly, the structure above will not tilt, ensuring the safety of the structure. Secondly, the pressure balance between the bottom of the floating pool and the bottom of the pontoon disappears. The pontoon rises horizontally without tilting, biasing, or contacting the bottom of the pool on one side. This avoids unnecessarily increasing the driving force required for rotation. When the structure needs to change its orientation, steps S1 and S2 described in Example 3 are executed to rotate the structure to the required angle, and then step S3 is executed to fix the structure. The solution provided by this invention for building a villa whose orientation can be changed at will is highly energy efficient. It is quiet, stable, safe, efficient, green, and energy-saving.

[0033] The water storage tank 11 in this design scheme can be integrated into the villa's garden pond. It blends seamlessly with the garden pond, avoiding any jarring effect on the aesthetics. The foundation of this structure, the main floating tank of the house foundation, is suspended within the floating tank. When the floating tank is full of water, the floating tank and the floating tank are not directly connected; water serves as the medium between them. In special circumstances, such as earthquakes, it provides a certain buffering effect and earthquake resistance.

[0034] Example 5: When the supported object is a machine tool weighing tens of tons, which needs to change direction frequently, such as a gun emplacement, this solution can be used. However, it requires precise turning angles. Figure 3 The gear drive mechanism shown (i.e., Embodiment 2) is an example. In this type of solution, if it is not desired to increase the volume of the pontoon to obtain greater buoyancy to balance its own weight, a liquid with a higher density can be selected. The buoyancy obtained is no longer the weight of the same volume of water as the pontoon, according to the buoyancy formula F_buoyancy = ρ_liquid * g * V_displaced, but the weight of the same volume of liquid with a higher density. For example, mercury can be used as the liquid to generate buoyancy. Mercury is a liquid with a density greater than iron, so it can easily float the entire turret.

[0035] Example 6: If the supported object weighs only a few tons, such as a car, this invention can be used as a vehicle turning device, applied to the mechanical turning of cars in narrow spaces, or used in front of garages to turn vehicles 90 degrees or 180 degrees into the garage. The implementation process can also be... Figure 3 The gear transmission mechanism shown (i.e., Embodiment 2) is illustrated. The pontoon can be replaced with foam board; for a typical family car weighing around two tons, the foam volume of the pontoon only needs to be about two cubic meters. This significantly reduces construction costs. Similarly, by performing steps S1-S3 as described in Embodiment 3, the vehicle can be turned around on the spot.

[0036] The working process and principle of this invention: The support structure and its weight are floated together in the floating pool by using pontoons. This eliminates the original friction between the foundation and the ground. There is only hydraulic adhesion resistance between the pontoons and the floating pool, with no friction, making horizontal rotation extremely easy and efficient.

[0037] A pontoon is the foundation for supporting heavy objects or structures, and it is completely sealed. Submerged entirely in water, it is airtight and watertight, providing the volume of water displaced to support the buoyancy of the load. The size of the pontoon is balanced with the weight of the load. The design should have redundancy, with the buoyancy slightly greater than the load. This allows the pontoon to be submerged further in water, especially if the load increases, thus balancing the change in gravity. The structure of the pontoon is modeled after a ship's hull. The pontoon must be able to rotate horizontally around its centerline, allowing the supported object to change direction freely. The pontoon is a rotating body, shown as a cylinder in the diagram. A floating pool is a water tank dug underground. The shape of the floating pool's walls is the same as that of the pontoon, except that its radius is slightly larger (about 1 cm). The bottom of the floating pool has a collection tank to collect drainage. The floating pool is connected to a storage tank via water pipes and a suction pump.

[0038] The water storage tank stores the drainage pumped up by the pump, thus having a water storage function; at the same time, it can also provide water storage as needed, pumping the stored water into the floating tank, causing the floating boxes in the tank to float, thus also having a water release function.

[0039] The collection tank is the lowest point of the entire floating pool, and all the water from the floating pool flows into it. Finally, the collected water is pumped into the storage tank via a suction pump.

[0040] The bidirectional suction pump and motor perform two functions: first, to extract drainage between the floating pool and the floating box and store it in a reservoir; second, to inject water into the floating pool in reverse order, causing the floating box in the floating pool to float.

[0041] The floating pontoon is constructed using leaf spring suspension wheels and leaf spring suspension wheels with drive motor gear sets, connected by three or more sets of upper and lower sidewall wheels. Inflated tires press the wheels against the sidewalls of the pontoon with pressure. The interaction of these multiple sets of sidewall wheel sets keeps the pontoon centered in the floating pool, preventing it from colliding with the side walls and maintaining a certain gap to avoid friction. The bottom set of leaf spring suspension wheels prevents uneven weight distribution when the pontoon floats. Uneven weight distribution would cause one side of the pontoon to contact the pool floor; the bottom suspension wheels ensure that sliding friction is converted to rolling friction. This also reduces the force required to move and rotate the pontoon, ensuring smooth rotation. When the supported structure needs to rotate, a pair of leaf spring suspension wheels with drive motor gear sets move simultaneously, generating rotational torque under motor drive, causing the pontoon to rotate. Ultimately, the pontoon-supported structure can rotate to change its horizontal orientation as needed.

[0042] When the supported object needs to rotate horizontally, the suction pump is turned on to inject water from the reservoir into the gap between the float tank and the float box. When the water level reaches the appropriate position, the buoyancy force on the float box equals the weight of the float box plus the weight of the supported object. The float box and the supported object then suspend in the float tank. Simultaneously, under the action of multiple sets of leaf spring suspension wheels, the balloon expansion effect of the tires pushes the float box from the edge of the tank towards the center. Under the combined action of multiple pushing forces, the float box suspends in the exact center of the buoyancy tank. There is a distance between the tank wall and the float box wall, and they do not contact each other, so there is no friction. Then the drive motor is turned on. Driven by a pair of symmetrical tires, the float box is rotated by the rotational torque, rotating the supported object to the required angle.

[0043] Because the pontoon is suspended in the center of the floatation tank and does not contact the tank, the required driving force is relatively small, resulting in high driving efficiency. Furthermore, because the gap between the pontoon and the tank is very small, the amount of water needed to fill this gap is minimal. This means that the filling time is short, and the cost of filling is minimal. However, the buoyancy generated when the tank is full is significant, resulting in substantial benefits. Essentially, a very small volume of water is used to float a large, heavy object. The cost-effectiveness and efficiency are extremely high. This is because buoyancy is the weight of the displaced liquid. The gap between the pontoon and the tank is very small. Their special structure determines that the special water film that generates buoyancy is very thin. The water film consists of a small amount of water, so the required water volume is also small. However, the volume enclosed by the water film is large, resulting in significant buoyancy. In summary, the extremely high cost-effectiveness and efficiency are determined by the special geometric structure and the formula for buoyancy: the magnitude of buoyancy is the product of the volume of displaced liquid and the density of the displaced liquid. The larger the volume of displaced liquid, the greater the buoyancy; the greater the density of the displaced liquid, the greater the buoyancy. The ratio of the magnitude of the buoyancy to the mass of the water film formed is the efficiency ratio of this scheme. The larger the ratio, the greater the efficiency.

[0044] Once the supported object has been rotated to the appropriate position, it needs to be secured. Turn on the suction pump. Water between the float and the float tank is collected in a collection tank. The suction pump then pumps the water from the collection tank into a storage tank. The suctioned water is stored in the storage tank to provide the necessary buoyancy for future use. After the water is sucked out, the float is no longer buoyant. The supported object, under its own weight, is secured by the friction between the float and the surface of the float tank, and the supporting force at the bottom of the float. This force is significant, ensuring the supported object is securely fixed after rotation.

[0045] It is understood that, for those skilled in the art, any equivalent substitutions or modifications to the technical solutions and inventive concepts of this invention should fall within the scope of protection of the appended claims.
