Description

Technical Field

[0001] This invention relates to the field of power device technology, specifically a novel buoyancy power device. Background Technology

[0002] Power units are primarily used to drive the movement of objects, such as electric motors, traction machines, external combustion engines, internal combustion engines, steam turbines, and engines, and they mainly rely on non-renewable energy sources as their power source. With the development of science and technology, power units using clean energy, such as wind turbines and hydroelectric turbines, are gradually being promoted and used. However, existing power units primarily based on clean energy are mainly used in the power generation field. How to better reduce energy consumption in power units used in daily life remains a significant challenge.

[0003] To address this, we designed and developed this new type of buoyancy power device, which uses liquid buoyancy to drive the movement of the traction rope, thereby realizing the lifting and lowering of the required load. It can be applied to cargo lifting, elevator operation, generator power generation and other fields. It mainly uses changes in buoyancy to achieve the movement of objects, requires less energy, greatly reduces energy consumption, and is highly practical. Summary of the Invention

[0005] To achieve the above objectives, the present invention provides the following technical solution: A novel buoyancy power device includes a water tank filled with water, a variable weight buoyancy barrel located in the water inside the water tank, the variable weight buoyancy barrel being able to adjust its own buoyancy and being able to move up and down in the water tank according to the change of its own buoyancy, the water tank being connected to a power traction rope, and a guide component being provided inside the water tank to ensure the stable movement of the variable weight buoyancy barrel.

[0006] As a further preferred embodiment of the present invention: the variable weight buoyancy tank has an opening facing downwards, and a drain plate that can move up and down is provided inside the variable weight buoyancy tank. The edge of the drain plate slides and seals against the inner wall of the variable weight buoyancy tank. A hydraulic cylinder is provided at the upper end of the variable weight buoyancy tank. The output end of the hydraulic cylinder passes through the variable weight buoyancy tank and is connected to the drain plate. An air pipe communicating with the inside of the variable weight buoyancy tank is connected to the upper end of the variable weight buoyancy tank.

[0007] As a further preferred embodiment of the present invention: the guide assembly includes a connecting plate fixedly disposed at the upper end of the variable weight buoyancy tank, and a plurality of guide rods are evenly disposed inside the water tank, the guide rods passing through the connecting plate and slidably connected to the connecting plate.

[0010] Compared with the prior art, the beneficial effects of the present invention are: This buoyancy power device adjusts the position of the drainage plate in the variable-weight buoyancy tank by controlling the hydraulic cylinder.

[0013] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. Example 1

[0014] Please see Figure 1This embodiment provides a novel buoyancy power device, including a water tank 1 filled with water. A variable-weight buoyancy tank 2 is disposed within the water tank 1 and positioned in the water. The variable-weight buoyancy tank 2 can adjust its own buoyancy and can move up and down within the water tank 1 according to changes in its buoyancy. Specifically, the variable-weight buoyancy tank 2 has an opening facing downwards. A vertically movable drainage plate 3 is disposed inside the variable-weight buoyancy tank 2. The edge of the drainage plate 3 slides and seals against the inner wall of the variable-weight buoyancy tank 2. As a conventional design, the variable-weight buoyancy tank 2 can be designed as a cylindrical shape, and a sliding sealing ring can be provided on the outside of the drainage plate 3 to achieve a sliding sealing connection. Its principle is the same as that of an existing syringe piston. The application will not be elaborated further; a hydraulic cylinder 6 is provided at the upper end of the variable weight buoyancy tank 2, and the output end of the hydraulic cylinder 6 passes through the variable weight buoyancy tank 2 and is connected to the drainage plate 3 to realize the up and down movement of the drainage plate 3. At the same time, an air pipe 7 communicating with the inside of the variable weight buoyancy tank 2 is connected to the upper end of the variable weight buoyancy tank 2, so that air can enter the variable weight buoyancy tank 2 through the air pipe 7 when the drainage plate 3 moves downward. It should be noted that the height design of the air pipe 7 should ensure that the air pipe 7 is always in communication with the outside air, and the hydraulic cylinder 6 should be a flexible hydraulic pipe with a length that can meet the lifting and lowering of the variable weight buoyancy tank 2. This design is a conventional operation familiar to those skilled in the art, and will not be elaborated further in this application.

[0015] To ensure the stable lifting and lowering of the variable weight buoyancy tank 2 in the water and prevent tilting, a guide assembly is provided inside the water tank 1. This assembly includes a connecting plate 8 fixedly installed at the upper end of the variable weight buoyancy tank 2, and multiple guide rods 9 evenly arranged inside the water tank 1. The guide rods 9 pass through the connecting plate 8 and are slidably connected to the connecting plate 8. The installation of the connecting plate 8 and the assembly relationship between the connecting plate 8 and the hydraulic cylinder 6 and the air pipe 7 are conventional designs familiar to those skilled in the art and will not be described in detail here.

[0016] In order to convert the lifting and lowering of the variable weight buoyancy tank 2 in the water into power output, a fixed rod 4 is provided at the bottom of the variable weight buoyancy tank 2. The fixed rod 4 is fixedly connected to the power traction rope 5. Multiple guide wheels 10 are provided inside the water tank 1 to guide the power traction rope 5, so that one end of the power traction rope 5 can be guided to the outside of the water tank 1 and connected to the object to be suspended.

[0017] In addition, such as Figure 5 As shown, as a conventional design familiar to those skilled in the art, in order to multiply the height and weight of the object, multiple guide wheels 10 can be set at the bottom of the fixed rod 4, and multiple corresponding guide wheels 10 can be set at the bottom of the water tank 1. The power traction rope 5 can be passed around the guide wheels 10 on the upper and lower sides in sequence. This is common knowledge and will not be elaborated further.

[0018] It should be noted that, as is common sense, for ease of assembly, the top of the water tank 1 is preferably designed with an opening; and the number and position of the guide wheels 10 will not be elaborated in this application, but can be referred to... Figure 1-3 As shown, the design can be based on actual needs and is a standard design, so it will not be elaborated further.

[0019] In practical applications, such as Figure 2 As shown, one end of the power traction rope 5 can be connected to the freight elevator 11. The position of the drainage plate 3 can be changed by the hydraulic cylinder 6. When the drainage plate 3 descends, the buoyancy inside the variable weight buoyancy tank 2 increases. When the buoyancy is greater than the weight of the freight elevator 11 and the cargo inside, the variable weight buoyancy tank 2 rises, which drives the freight elevator 11 to rise through the power traction rope 5. When the drainage plate 3 rises, the air inside the variable weight buoyancy tank 2 decreases, the water volume under the drainage plate 3 inside the variable weight buoyancy tank 2 increases, and the buoyancy of the variable weight buoyancy tank 2 decreases. When the buoyancy is less than the weight of the freight elevator 11, the freight elevator 11 descends, which in turn drives the variable weight buoyancy tank 2 to descend, thus realizing the lifting and lowering movement of the freight elevator 11.

[0020] At the same time, such as Figure 4 As shown, the power unit can be applied to the lifting and lowering operation of two freight elevators 11 according to actual needs. Based on the operation of a single freight elevator 11, two more power traction ropes 5 are added. One of the power traction ropes 5 connects the upper ends of the two freight elevators 11 through the guide wheel 10. At the same time, the upper end of the outermost freight elevator 11 is also connected to the upper end of the variable weight buoyancy tank 2 through a power traction rope 5. When the variable weight buoyancy tank 2 moves up and down in the water tank 1 by changing its buoyancy, it drives the two freight elevators 11 to move in opposite directions. At the same time, the device can also be applied to the lifting and lowering operation of multiple freight elevators 11 according to needs. It is only necessary to arrange the power traction ropes 5 according to common sense. This application will not elaborate on the limitations.

[0021] In addition, such as Figure 3 As shown, one end of the power traction rope 5 can be wrapped around the generator main shaft 12 and fixed to the upper end of the variable weight buoyancy tank 2. When the variable weight buoyancy tank 2 moves up and down, it drives the power traction rope 5 to reciprocate, thereby realizing the rotation of the generator main shaft 12 and realizing the generator's power generation. It should be noted that, as a conventional design, the power traction rope should not be limited to the rope structure. It should be preferably replaced by a transmission chain. The guide wheel 10 is a guide sprocket. The corresponding sprocket can be set on the generator main shaft 12. This is a conventional design and will not be described in detail.

[0022] Meanwhile, it should be noted that when the variable weight buoyancy tank 2 moves up and down, the position of the drainage plate 3 inside the variable weight buoyancy tank 2 should change at any time according to the position of the variable weight buoyancy tank 2 in the water, and the buoyancy force on the variable weight buoyancy tank 2 should be adjusted at any time to ensure that the variable weight buoyancy tank 2 and the suspended object are always at a suitable operating speed. This design is common knowledge familiar to those skilled in the art. In practical applications, the height of the variable weight buoyancy tank 2 can be monitored by designing a sensor in the water tank 1, and then the movement of the drainage plate 3 can be controlled by controlling the hydraulic cylinder 6. This is common knowledge and will not be elaborated further in this application.

[0023] Additionally, it should be noted that, as is common sense, changing the buoyancy of the variable-weight buoyancy tank 2 by altering the position of the drainage plate 3 does not allow for precise buoyancy control. This results in an inability to accurately control the height of the variable-weight buoyancy tank 2. Therefore, when applying this power unit to devices such as freight elevators that require precise start and stop positions, such as... Figure 2 As shown, as a conventional design, a traction machine 13 can be designed on the power traction rope 5. During the lifting motion, the traction machine 13 does not work, and the power traction rope 5 drives the drum of the traction machine 13 to rotate. When the freight elevator 11 is about to reach the designated stopping height, the traction machine 13 works to ensure that the height of the freight elevator 11 can be accurately determined. However, when this power unit is applied to a device that does not require precise stopping, there is no need to design a traction machine 13 for auxiliary work. This design is a conventional design familiar to those skilled in the art and will not be described in detail here.

[0024] In practical applications, the water tank 1 has a diameter of 1.5 meters and sufficient height, and the variable weight buoyancy tank 2 has a diameter of 1.4 meters and a height of 2.5 meters. When the variable weight buoyancy tank 2 is filled with gas after being drained and inflated, it can generate 3846 kg of buoyancy. The weight of the variable weight buoyancy tank 2 together with the hydraulic cylinder 6 is about 800 kg. Therefore, this device can be used for lifting objects in freight elevator 11 or other fields. At the same time, the volume of the water tank 1 and the variable weight buoyancy tank 2 can be customized according to actual needs to meet the power requirements of different fields.

[0025] It should be noted that the above embodiments are only specific and clear descriptions of the technical solutions and features of this application. Solutions or features that are prior art or common knowledge to those skilled in the art will not be described in detail in the above embodiments.

[0026] Furthermore, the technical solutions of this application are not limited to the above embodiments. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
