Description

Technical Field

[0001] This invention relates to a conveying device that uses a float as a carrier to carry items and utilizes water buoyancy to transport items from a low place to a high place. In particular, it relates to a space conversion chamber with a changeable channel, which allows the float to enter the liquid space without resistance from the bottom of a water pipe filled with liquid. Background Technology

[0002] Known technologies for transporting goods using buoyancy can only operate on horizontal surfaces, such as by boat. To use buoyancy to transport goods from a lower to a higher location, the required device would be a lightweight object as a carrier and a water pipe filled with liquid. The lightweight object must enter the water pipe from the bottom, but known technologies have not solved this problem.

[0003] Therefore, to develop this low-energy, environmentally friendly, fast-transporting device that uses water buoyancy to transport goods, the technical problem of how to get lightweight objects, such as floats, into the water pipe from the bottom must first be overcome. Summary of the Invention

[0004] To achieve the above objectives, the liquid flotation conveying device of the present invention includes a space conversion chamber with a changeable channel. The upper channel is connected to a water pipe filled with liquid, and the side channel is connected to the external atmosphere. A float carrying an item enters the chamber through the side channel. After the chamber is filled with liquid, the liquid in the water pipe and the space conversion chamber are combined. The float rises and exits through the upper channel, then enters the water pipe from the bottom. The float carrying the item quickly rises to a receiving platform at a higher water surface.

[0005] The liquid flotation conveying device of the present invention includes a plurality of channel space conversion chambers, a plurality of channel gates, a water storage pressure cylinder device, a suction and exhaust pipe, a water pipe filled with liquid, a drain pipe, and at least one float.

[0006] According to the present invention, a suction and exhaust pipe is installed at an appropriate location in the multiple-channel space conversion chamber; a float outlet gate is provided at the upper channel opening of the space conversion chamber, which is connected to a water pipe filled with liquid; a float inlet gate is provided at the side channel opening, which communicates with the external space; a grid plate is provided at the lower channel inlet, and the device at the channel outlet has two implementation modes: the first is a non-drainage mode, in which a water storage pressure cylinder device is connected at the lower channel outlet; the second is a drainage mode, in which a gate is provided at the lower channel outlet, which is connected to a drain pipe.

[0007] The float according to the present invention is a lightweight object. If it is hollow, it can be used to load items. A waterproof fastener is provided on the outside of the float, and the items are fixed by the fastener after being placed in it. If the float is solid, a hook is provided on the outside, which can be used to hang waterproof packaged items.

[0008] The water storage pressure cylinder device according to the present invention includes: a pressure control unit, a water storage cylinder tube, a sealing piston, and a pressure device. One end of the piston rod of the pressure device is connected to the sealing piston inside the water storage cylinder tube. The guide of the pressure device can control the rise or fall of the sealing piston inside the water storage cylinder tube; in particular, the liquid volume stored in the water storage cylinder tube must be equal to or greater than the liquid volume inside the space conversion chamber. The function of the water storage pressure cylinder device is as follows: when the pressure device of the pressure control unit is activated to descend, the sealing piston inside the water storage cylinder tube descends, and all the liquid inside the space conversion chamber is drawn into and stored in the water storage cylinder tube; when the pressure device of the pressure control unit is activated to ascend, the sealing piston inside the water storage cylinder tube rises, and all the liquid stored in the water storage cylinder tube is injected into the space conversion chamber.

[0009] According to the present invention, the main components of the suction and exhaust pipe include: a screw, a sealing ring, and a hollow object. The function of the suction and exhaust pipe is as follows: when the pressure controller of the pressure control unit is activated and the pressure lowering guide is engaged, the piston rod of the pressure controller retracts, pulling the sealing piston inside the water storage tank tube downwards. Due to the suction force, the screw inside the suction and exhaust pipe descends, causing the sealing ring installed below the screw to disengage from the airflow passage between the upper and lower pipes. Air flows in through the vent on the upper cover, allowing the liquid in the space conversion chamber to be drawn into the water storage tank tube for storage. When the pressure controller of the pressure control unit is activated and the pressure uppering guide is engaged, the piston rod of the pressure controller extends, pushing the sealing piston inside the water storage tank tube upwards, thus storing the liquid. The liquid stored in the cylinder tube is injected into the space conversion chamber under high pressure, and the gas in the chamber is discharged through the vent on the top cover of the intake and exhaust pipe. When the space conversion chamber is full of liquid, the liquid rises into the intake and exhaust pipe, pushing up the hollow object installed at the lower end of the screw in the intake and exhaust pipe. When the hollow object and the screw are pushed to the set position, the sealing ring installed below the screw blocks the vent between the upper and lower pipes in the intake and exhaust pipe, sealing the gap for gas flow between the screw and the pipe, preventing the liquid from being discharged from the vent, and making the space conversion chamber completely sealed and airtight.

[0010] According to the non-drainage embodiment of the present invention: the space conversion chamber has an air intake and exhaust pipe at an appropriate position above, and a water storage pressure cylinder device at the lower passage opening. Open the buoy inlet gate of the side passage of the space conversion chamber, and place the buoy carrying the items (the weight of the items is less than the buoy's buoyancy) into the empty chamber. The buoy will remain on the grid plate at the entrance of the lower passage. Next, close the buoy inlet gate of the side passage, and activate the upward guide of the pressure control unit of the water storage pressure cylinder device at the lower passage entrance. The piston rod of the pressure device extends, pushing the sealed piston inside the water storage cylinder pipe upward, injecting the high-pressure liquid into the space conversion chamber. Air inside the chamber is discharged through the intake and exhaust pipes. When the liquid enters the intake and exhaust pipes, it pushes the hollow object installed at the lower end of the screw inside the intake and exhaust pipes. When the hollow object and the screw are pushed to a set position, the sealing ring installed below the screw blocks the vent between the upper and lower pipes in the intake and exhaust pipes, sealing the gap for gas flow between the screw and the pipes, preventing the high-pressure liquid from escaping. The liquid flows out through the orifice, keeping the space conversion chamber completely sealed. High-pressure input continues, increasing the hydraulic pressure within the chamber. When the pressure inside the chamber exceeds or equals the pressure at the bottom of the water pipe connected to it, the float outlet gate of the upper channel is immediately opened, connecting the upper water pipe to the interior of the lower space conversion chamber. The upper and lower liquids merge, and the float rapidly rises, entering the water pipe from the bottom. Simultaneously, the pressure device discharges all remaining liquid from the storage tank under high pressure. As the float enters the liquid space within the water pipe from the bottom, buoyancy causes it to rise rapidly. Upon reaching the water surface, it loses buoyancy and remains on the surface. Workers on the higher platform receive the float, unfasten the fasteners, remove the carried items, and place the empty float into an empty pipe connected to the ground platform. The empty float slides down to the ground platform, where workers remove it and replace the items. When preparing to place the space conversion chamber again, the liquid inside must first be drained to empty the chamber. Therefore, first close the float outlet gate of the upper passage of the space conversion chamber, then activate the water storage pressure cylinder device at the lower passage opening. This drives the pressure controller to descend, causing the piston rod to retract and pull the sealing piston downwards. Due to suction, the screw in the intake / exhaust pipe descends, disengaging the sealing ring below the screw from the airflow channel between the upper and lower pipes. Air flows in through the vent on the top cover of the intake / exhaust pipe, and all the liquid inside the space conversion chamber is drawn in and stored in the water storage pressure cylinder. Once the space conversion chamber is empty, the float inlet gate of the side passage can be opened, a float can be placed in, and the process can be repeated continuously to transport items to the higher work platform.

[0011] According to a drainage embodiment of the present invention: a grid plate is installed at the entrance of the lower passage of the space conversion chamber for a float to rest on; a drainage gate is installed at the outlet of the lower passage, connected to a drainage pipe. The float inlet gate of the side passage of the space conversion chamber is opened, and a float carrying items (the weight of the items is less than the buoyancy of the float) is placed into the empty chamber cavity, where the float rests on the grid plate; then, the float inlet gate of the side passage of the space conversion chamber and the drainage gate of the lower passage are closed, leaving only the float outlet gate of the upper passage of the space conversion chamber open, allowing liquid from the upper connecting water pipe to flow into and fill the space conversion chamber. When the upper water pipe is connected to the interior of the lower space conversion chamber, the upper and lower... When the liquid is integrated, the buoy rises rapidly, entering the liquid space within the water pipe from the bottom. Buoyancy causes the buoy to ascend quickly, losing buoyancy upon reaching the surface and remaining there. Personnel on the higher work platform retrieve the items carried by the buoy and place the empty buoy into an empty pipe connecting to the lower work platform. The empty buoy then slides down to the lower platform, where personnel open it and place items inside. If other items are too large to fit inside the empty buoy, a buoy hook is used to suspend them. Before placing the buoy back into the space conversion chamber, the liquid inside must be drained to ensure the chamber is empty. Therefore, first, the float outlet gate of the upper channel is closed. Then, the drain gate of the lower channel is opened, allowing the liquid in the space conversion chamber to be drained into a storage tank via the drain pipe connected to the lower channel. Once the space conversion chamber is clear, the drain gate of the lower channel is closed. Next, the float inlet gate of the side channel is opened, and personnel on the ground work platform place the float, already containing the items, into the space conversion chamber. This process is repeated sequentially, with the float continuously transporting items to higher positions. Simultaneously, water drained from the space conversion chamber into the storage tank is pumped out and continuously injected into the water supply pipe connected to the top of the pipe, replenishing the liquid drained from the pipe.

[0012] The advantages of this invention are that it provides a new technology for transporting goods quickly, with low energy consumption, continuous operation, and no height limit. The weight of the goods carried by the buoy can vary depending on the size of the buoy carrier and the capacity of the conveying equipment. A larger buoy has greater buoyancy and can carry a larger weight of goods. For example, a buoy with a diameter of 30cm has a buoyancy of 14kg and can carry goods weighing less than 14kg; a buoy with a diameter of 1 meter increases the buoyancy to 523kg and can suspend and transport goods weighing less than 523kg.

[0059] A liquid flotation conveying device includes a multi-channel space conversion chamber 1, a multi-channel gate 4, a water storage pressure cylinder 3, a suction and exhaust pipe 2, a water pipe 5 filled with liquid 6, a drain pipe 12, and at least one float 7.

[0060] Please refer to Figure 3 , Figure 4The multiple-channel space conversion chamber 1 is equipped with an intake and exhaust pipe 2 at an appropriate position; a float outlet gate 4-2 is provided at the upper channel opening 1-2 of the space conversion chamber 1, which is connected to a water pipe 5 filled with liquid 6; a float inlet gate 4-1 is provided at the side channel opening 1-1, which is connected to the external space; a grid plate 11 is provided at the entrance of the lower channel 1-3, and the device at the outlet of the lower channel 1-3 has two implementation modes: the first is the non-drainage mode, in which a water storage pressure cylinder device 3 is provided at the outlet of the lower channel; the second is the drainage mode, in which a drainage gate 4-3 is provided at the outlet of the lower channel 1-3, which is connected to a drainage pipe 12.

[0061] Please refer to Figure 1 , Figure 3 , Figure 4 The water storage pressure cylinder device 3 includes: a pressure control platform 3-1, a water storage cylinder pipe 3-5, a sealing piston 3-4, and a pressure device 3-2. One end of the piston rod 3-3 of the pressure device 3-2 is connected to the sealing piston 3-4 inside the water storage cylinder pipe 3-5. The guide of the pressure device 3-2 can control the rise or fall of the sealing piston 3-4 inside the water storage cylinder pipe 3-5; in particular, the capacity of the liquid 6 stored in the water storage cylinder pipe 3-5 must be equal to or greater than the capacity of the liquid 6 in the space conversion chamber 1. The function of the water storage pressure cylinder device 3 is as follows: when the pressure controller 3-2 of the pressure control unit 3-1 is activated to descend, the sealing piston 34 in the water storage cylinder tube 3-5 descends, and all the liquid 6 in the space conversion chamber 1 is sucked into the water storage cylinder tube 3-5 for storage; when the pressure controller 3-2 of the pressure control unit 3-1 is activated to ascend, the sealing piston 3-4 in the water storage cylinder tube 3-5 rises, and all the liquid 6 stored in the water storage cylinder tube 3-5 is injected into the space conversion chamber 1.

[0062] Please refer to Figure 8 and Figure 9The intake and exhaust pipe 2 includes: a screw telescopic hole 2-2, at least one air hole 2-3, a screw 2-4, a nut 2-5, a sealing ring 2-6, and a hollow object 2-1. The hollow pipe inside the intake and exhaust pipe 2 is divided into upper and lower sections, with the inner diameter of the upper pipe being smaller than that of the lower pipe. The intake and exhaust pipe is provided with an upper cover, which has at least one air hole 2-3 and a screw telescopic hole 2-2. The intake and exhaust pipe 2 is installed at an appropriate position in the space conversion chamber 1 (e.g., the top of the space conversion chamber 1), and the hollow pipe inside the intake and exhaust pipe 2 communicates with the cavity of the space conversion chamber 1. The screw 2-4 is divided into upper and lower sections, with the outer diameter of the upper section being smaller than that of the lower section. The upper section of the screw 2-4 passes through the screw telescopic hole 2-2 in the upper cover. A nut 2-5 is connected to the top of the screw 2-4. When the screw 2-4 descends to a set position, the nut 2-5 presses against the upper cover to achieve a positioning effect. The outer diameter of the lower section of the screw 2-4 is smaller than the inner diameter of the lower pipe in the intake / exhaust pipe 1, which allows for airflow. At an appropriate position (e.g., the tail end) on the lower section of the screw 2-4, a sealing ring 2-6 and a hollow object 2-1 are installed. The outer diameter of the sealing ring 2-6 and the hollow object 2-1 is larger than the inner diameter of the upper pipe in the intake / exhaust pipe 2, but smaller than the inner diameter of the lower pipe.

[0063] Please refer to Figure 9 The working state of the intake and exhaust pipe 2 is as follows: When the water storage pressure cylinder device 3 is activated, the liquid 6 in the water storage cylinder pipe is filled into the space conversion chamber 1 under high pressure. The liquid 6 then enters the intake and exhaust pipe 2, pushing the hollow object 2-1 at the tail of the screw 2-4 upward. When the screw 24 rises to the set position, the sealing ring 2-6 blocks the airflow inlet and outlet between the upper and lower pipes, making the intake and exhaust pipe 2 and the space conversion chamber 1 completely sealed, preventing the liquid 6 that continues to be injected under high pressure from flowing out of the air hole 2-3 of the intake and exhaust pipe 2. Please refer to... Figure 8 When the water storage pressure cylinder device 3 is activated, the piston rod 3-3 of the pressure device 3-2 is driven to retract and the sealing piston 3-4 is pulled down, drawing the liquid 6 in the space conversion chamber 1 into the water storage cylinder pipe 3-5. Due to the suction, the screw 2-4 in the suction and exhaust pipe 2 descends. When the screw 2-4 descends to the set position, the nut 2-5 will press against the upper cover 2-5 of the suction and exhaust pipe 2. The sealing ring 2-6 at the tail of the screw 2-4 disengages from the airflow channel between the upper and lower pipes. The airflow flows into the pipe through the air hole 2-3 of the upper cover, passes through the gap between the screw 2-4 and the pipe, and flows into the space conversion chamber 1, so that the liquid 6 is smoothly drawn into the water storage cylinder pipe.

[0064] This invention has two implementation modes. To better understand the technical content of this invention, specific embodiments of the two modes are described below.

[0065] A specific embodiment of the non-drainage mode of the liquid flotation conveying device of the present invention: Please refer to Figure 1 , Figure 3 and Figure 4The multiple-channel space conversion chamber 1 contains liquid 6, which is either output or sucked in and stored by the water storage pressure cylinder 3. Since the space conversion chamber 1 is in a closed space, air is required to inject or discharge the liquid 6. Therefore, an air intake and exhaust pipe 2 needs to be installed at an appropriate location in the space conversion chamber 1.In practice, the float inlet gate 4-1 of the side passage 1-1 of the space conversion chamber 1 is opened, and the float 7 carrying the items (the weight of the items 9 is less than the buoyancy of the float 7) is placed into the chamber cavity, which is now empty of liquid 6. The float 7 rests on the grid plate 11 at the entrance of the lower passage 1-3. Immediately afterwards, the float inlet gate 4-1 of the side passage 1-1 is closed, and the upward guide of the pressure control mechanism 3-1 of the water storage pressure cylinder device 3 in the lower passage 1-3 is activated, causing the piston rod 3-3 of the pressure device 3-2 to extend and push the sealed piston 3-4 in the water storage cylinder tube 3-5 to rise, injecting the liquid 6 in the cylinder tube into the space conversion chamber 1. The air in the chamber is discharged through the intake and exhaust pipe 2. When the liquid 6 enters the intake and exhaust pipe 2... The hollow object 2-1 installed at the tail of the screw 2-4 inside the intake and exhaust pipe 2 is pushed up. When the hollow object 2-1 and the screw 2-4 are pushed up to the set position, the sealing ring 2-6 installed below the screw 2-4 blocks the vent between the upper and lower pipes inside the intake and exhaust pipe 2, sealing the gap for gas flow between the screw 2-4 and the pipe, preventing the high-pressure injected liquid 6 from flowing out from the vent 2-3. The space conversion chamber 1 is in a completely sealed state. When the liquid 6 continues to be injected under high pressure, the hydraulic pressure will continue to increase. When the pressure inside the chamber is greater than or equal to the pressure at the bottom of the water pipe 5 connected to the upper part, the float outlet gate 4-2 of the upper channel 1-2 is immediately opened, allowing the water pipe 5 above to connect with the space conversion chamber below. The internal structure of pipe 1 is interconnected, with the upper and lower liquids 6 combined. The float rises rapidly and enters the water pipe 5 from the bottom. Simultaneously, the pressure device 3-2 discharges all remaining liquid 6 from the water storage tank pipe 3-5. When the float 7 enters the liquid space within the water pipe 5 from the bottom, buoyancy causes it to rise rapidly until it loses buoyancy and rests on the water surface. Workers on the elevated work platform 10-2 retrieve the float 7, open the fastener 7-1, remove the carried item 9, and place the empty float 7 into an empty pipe 8 connecting to the ground work platform 10-1. The empty float 7 slides down into the ground work platform 10-1. Workers remove the empty float 7, re-insert the item 9, and then prepare to place the item 9 back into the pipe. When the space conversion chamber 1 is in operation, the liquid 6 in the chamber must be drained first to empty the space conversion chamber 1. Therefore, first, close the float outlet gate 4-2 of the upper channel 1-2 of the space conversion chamber 1. Then, start the descent guide of the pressure control unit 3-1 to drive the water storage pressure cylinder device 3 of the lower channel 1-3, causing the piston rod 3-3 of the pressure device 3-2 to retract and the sealing piston 3-4 to descend. Due to the suction, the screw 2-4 in the suction and exhaust pipe 2 descends, and the sealing ring 2-6 installed below the screw 2-4 disengages from the airflow channel between the upper and lower pipes. Air flows in through the air hole 2-3 on the top cover of the suction and exhaust pipe 2, and all the liquid 6 in the space conversion chamber 1 is sucked into the water storage cylinder pipe 3-5 for storage.When the space conversion chamber 1 is empty, the float inlet gate 4-1 of the side passage 1-1 can be opened, and the float 7 can be placed in again. This process is repeated in sequence, and the items 9 are continuously transported to the high working platform 10-2.

[0066] A specific embodiment of the drainage mode of the liquid flotation conveying device of the present invention: Please refer to Figure 2 , Figure 5 and Figure 6The multiple-channel space conversion chamber 1 contains liquid 6, which flows in through the water pipe 5 connected to the upper channel 1-2 and flows out through the lower channel 1-3. A baffle plate 11 is installed at the entrance of the lower channel 1-3 of the space conversion chamber 1 to allow the float 7 to stay, and a drain gate 4-3 is installed at the exit of the lower channel 1-3, connected to a drain pipe 12. In practice, the float inlet gate 4-1 of the side passage 1-1 of the space conversion chamber 1 is opened, and the float 7 carrying the item 9 (the weight of the item 9 is less than the buoyancy of the float 7) is placed into the chamber, which is now empty of liquid 6. The float 7 rests on the grid plate 11. Next, the float inlet gate 4-1 of the side passage 1-1 of the space conversion chamber 1 is closed, as is the drain gate 4-3 of the lower passage 1-3. The float outlet gate 4-2 of the upper passage 1-2 of the space conversion chamber 1 is opened separately, allowing the liquid 6 in the water pipe 5 to flow into and fill the space conversion chamber 1. At this time, the upper water pipe 5 and the lower space conversion chamber... Internally connected, the upper and lower liquids 6 are combined into one. The float 6 rises rapidly, entering the liquid space 6 inside the water pipe 5 from the bottom. The buoyancy of the water causes the float 7 to rise rapidly. Upon reaching the water surface, it loses buoyancy and remains on the surface. Personnel on the high working platform 10-2 retrieve the item 9 carried by the float 7 and place the empty float 7 into an empty pipe 8 connecting to the ground working platform 10-1. The empty float 7 falls into the ground working platform 10-1. The personnel open the empty float 7 and put the item 9 back in (or, if other items are too large to fit into the hollow float 7, the float 7 is used to carry the items by suspending them with hooks 7-2). When preparing to put the float 7 back into the space conversion chamber 1, the liquid 6 in the space conversion chamber 1 must first be drained to empty the chamber. Therefore, firstly, the float outlet gate 4-2 of the upper channel 1-2 is closed. Then, the drain gate 4-3 of the lower channel 1-3 is opened, and the liquid 6 in the space conversion chamber 1 is discharged into the water storage tank 15 through the drain pipe 12 connected to the lower channel 1-3. When the space conversion chamber 1 is emptied, the drain gate 4-3 of the lower channel 1-3 is closed. Next, the float inlet gate 4-1 of the side channel 1-1 is opened, and the float 7 carrying the item 9 is placed into the chamber. This process is repeated sequentially, with multiple floats 7 continuously transporting the item 9 to a higher position. Simultaneously, the liquid discharged from the space conversion chamber 1 into the water storage tank 15 is pumped out by the pump 13 and continuously injected into the water pipe 5 via the water supply pipe 14, replenishing the liquid 6 discharged from the water pipe 5.

[0067] The above description is illustrative only and not restrictive of the present invention. Those skilled in the art will understand that many modifications, variations or equivalents can be made without departing from the spirit and scope defined by the claims, and all such modifications, variations or equivalents will fall within the protection scope of the present invention.
