Description

Technical Field

[0001] The present invention relates to the technical field of ship engineering, and more specifically, to a flip-type floating box. Background Art

[0002] A floating box for a ship is a structural component installed on both sides of the ship to increase the stability and buoyancy of the ship. It is usually made of high-strength, water-immersion-resistant and corrosion-resistant materials. Its working principle is based on Archimedes' principle. When the floating box is immersed in water, it will displace a certain volume of water, thereby generating an upward buoyancy force. When the ship is carrying heavy loads or in special working conditions, the additional buoyancy provided by the floating box can assist the ship in maintaining a floating state and prevent it from sinking due to excessive load resulting in excessive draft.

[0003] However, most of the existing floating boxes are welded or fixed to both sides of the ship through a specific structure. With the fixed-installed floating box, part of the floating box will always be below the water surface. For ships with less load that do not require the floating box to provide buoyancy, the floating box submerged in water will greatly increase the water-facing area of the ship, resulting in a reduction in the ship's propulsion efficiency, increased fuel consumption and operating costs. Summary of the Invention

[0009] On the basis of the foregoing solution, further, the sliding limiting part includes a bucket - shaped water collecting block and a sliding limiting rod; The bucket - shaped water collecting block is arranged in the sliding floating box body, and a water collecting cavity is formed in the middle of the bucket - shaped water collecting block; A plurality of sliding limiting rods are provided. One end of the sliding limiting rod is arranged on the bucket - shaped water collecting block, and the other end of the sliding limiting rod penetrates and is hermetically slidably arranged on the fixed floating box body.

[0010] On the basis of the foregoing solution, the air supply assembly includes an air supply pump and an air supply pipe; A plurality of air supply pumps are provided, and the air supply pumps are installed on the fixed floating box body; A plurality of air supply pipes are provided. The air supply pipes correspond to the air supply pumps one by one. The air supply pipes are communicatively arranged between the air outlet end of the air supply pump and the fixed floating box body, and an air supply valve is installed on each air supply pipe.

[0011] On the basis of the foregoing solution, the exhaust assembly includes an exhaust pump and an exhaust valve; The exhaust pump is installed on the fixed floating box body, and the intake end of the exhaust pump is communicated with the fixed floating box body; The exhaust valve is installed on the intake end of the exhaust pump.

[0012] As a preferred technical solution of the present application, the drainage assembly includes a drainage fixed pipe, a drainage sliding pipe, and a drainage valve; The drainage fixed pipe penetrates and is sealed on the fixed floating box body; One end of the drainage sliding pipe is arranged on the funnel-shaped water collecting block through a plurality of positioning blocks.

[0014] Furthermore, on the basis of the foregoing solution, a plurality of heat dissipation holes are provided on one side of the flip-type power box.

[0015] The beneficial effects of the present invention are as follows: 1. In the present invention, after the flip-type power box is installed on one side of the ship body, by starting the power motor in the flip power mechanism, the flip limit rod can be driven to move, and the position of the floating box part can be flipped and adjusted. When the ship does not need buoyancy support, the floating box part can be moved above the ship body to reduce the water-facing area of the ship body. As the weight of the ship's load increases, the power motor can be started to move part of the floating box part below the water surface to increase the buoyancy of the ship; 2. In the present invention, after part of the floating box part is moved below the water surface, the air supply valve in the air supply assembly can be opened, and the air supply pump can be started. The air supply pump is used to introduce gas into the fixed floating box body to increase the air pressure in the fixed floating box body. As the pressure in the fixed floating box body increases, the sliding floating box body will move in the direction below the water surface. Through the movement of the sliding floating box body, the volume of the floating box part is increased, and by increasing the drainage volume of the floating box part, the buoyancy of the floating box part is improved, thereby increasing the load capacity of the ship body. Similarly, by starting the exhaust pump, the gas in the fixed floating box body can be discharged, and the sliding floating box body can be moved into the fixed floating box body. Compared with the traditional floating box with a fixed volume, the telescopic floating box can not only adjust the magnitude of the buoyancy according to the different loads of the ship, but also when the sliding floating box body is completely inside the fixed floating box body, when the floating box part is moved below the water surface by the flip power mechanism, the problem that the power component is damaged due to a large power caused by buoyancy can be greatly reduced.

[0016] 3. In the present invention, when the position of the sliding floating box body is adjusted by sliding, if the long-term sliding friction causes a decrease in sealing and results in a small amount of water seepage, and the ship cannot be repaired during navigation, the water that seeps into the sliding floating box body will be collected at the water collection cavity through the funnel-shaped water collection block. At this time, in order to prevent the pressure in the sliding floating box body from decreasing, the air supply pump can be started to continuously supply gas into the fixed floating box body. At this time, the drain valve in the drain assembly can be opened, and under the action of pressure, the water collected at the water collection cavity will be discharged from the drain fixed pipe along the drain sliding pipe.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0020] Next, in combination with the embodiments of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the scope of protection of the present invention.

[0021] As Figures 1 to 6 shown, this embodiment proposes a flip-type floating box, which includes a flip-type power box 1, a flip power mechanism 001 with a self-locking function, a flip limit rod 2, and a floating box part 002 with a sealing and telescopic function.

[0022] Among them, multiple flip limit grooves are provided on one side of the flip-type power box 1.

[0023] Specifically, the flip power mechanism 001 is arranged in the flip-type power box 1. The flip power mechanism 001 includes a power dividing plate 3, a power shaft 4, a power worm gear 5, a power worm 6, and a power component. The power dividing plate 3 is arranged in the flip-type power box 1. The power shaft 4 passes through multiple flip limit grooves and is sealed and rotatably arranged on the flip-type power box 1. One end of the flip limit rod 2 is arranged on the power shaft 4. The power worm gear 5 is arranged on the power shaft 4. The power worm 6 is rotatably arranged between the flip-type power box 1 and the power dividing plate 3. The power worm 6 meshes with the power worm gear 5. The power component is arranged in the flip-type power box 1. The power component is connected to one end of the power worm 6 and is used to drive the power worm 6 to rotate.

[0024] Among them, the power component includes a power gearbox 7 and a power motor 8. The power gearbox 7 is installed in the flip-type power box 1. The output end of the power gearbox 7 is connected to one end of the power worm 6. The power motor 8 is installed in the flip-type power box 1. The input end of the power motor 8 is connected to the input end of the power gearbox 7.

[0025] Specifically, when the power motor 8 is started, the output end of the power motor 8 drives the input end of the power gearbox 7 to rotate. Through the speed reduction and torque increase of the power gearbox 7, the output end of the power gearbox 7 drives the power worm 6 to rotate. The rotation of the power worm 6 drives the power worm gear 5 to rotate. Through the rotation of the power worm gear 5, the power shaft 4 is driven to rotate. Under the self-locking cooperation of the power worm 6 and the power worm gear 5, when adjusting the rotation angle of the power shaft 4, the stability of the position of the power shaft 4 can be effectively ensured, and the purpose of self-locking is achieved.

[0026] It should be supplemented that multiple heat dissipation holes are provided on one side of the flip-type power box 1 for the heat dissipation operation of the power component.

[0027] As described above, there are multiple flipping limit rods 2, and the flipping limit rods 2 correspond to the flipping limit grooves one by one. The flipping limit rods 2 are located in the flipping limit grooves, and one end of the flipping limit rod 2 is connected to the flipping power mechanism 001. Specifically, by rotating the power shaft 4, the flipping limit rod 2 can be driven to perform a flipping operation.

[0028] As described above, the floating box part 002 is arranged at the other end of the flipping limit rod 2, and an air supply component 003, an exhaust component 004 and a drainage component 005 are arranged on the floating box part 002.

[0029] Among them, the floating box part 002 includes a fixed floating box body 9, a sliding floating box body 10 and a sliding limit part with a water collecting function. The fixed floating box body 9 is arranged on the flipping limit rod 2. The sliding floating box body 10 penetrates and is hermetically slidably arranged on one side of the fixed floating box body 9. The sliding limit part is arranged in the sliding floating box body 10 and penetrates and is hermetically slidably arranged on the fixed floating box body 9. The sliding limit part includes a bucket-shaped water collecting block 11 and a sliding limit rod 12. The bucket-shaped water collecting block 11 is arranged in the sliding floating box body 10, and a water collecting cavity is formed in the middle of the bucket-shaped water collecting block 11. There are multiple sliding limit rods 12. One end of the sliding limit rod 12 is arranged on the bucket-shaped water collecting block 11, and the other end of the sliding limit rod 12 penetrates and is hermetically slidably arranged on the fixed floating box body 9.

[0030] Compared with the traditional floating box with a fixed volume, the telescopic floating box can not only adjust the magnitude of buoyancy according to different ship loads, but also greatly reduce the problem that the power component is damaged due to a large power when the floating box part 002 is moved below the water surface by the flipping power mechanism 001 when the sliding floating box body 10 is completely inside the fixed floating box body 9.

[0031] It should be added that the flipping power mechanism 001 needs to be arranged on one side of the ship deck. When the flipping power mechanism 001 drives the floating box part 002 to flip, the floating box part 002 can extend out of one side of the deck.

[0032] And by arranging the sliding limit rod 12, the stability of the sliding floating box body 10 moving on one side of the fixed floating box body 9 can be effectively ensured, and the sealing performance between the sliding floating box body 10 and the fixed floating box body 9 can be ensured.

[0033] Among them, the air supply component 003 includes an air supply pump 13 and an air supply pipe 14. There are multiple air supply pumps 13, and the air supply pumps 13 are installed on the fixed floating box body 9. There are multiple air supply pipes 14, and the air supply pipes 14 correspond to the air supply pumps 13 one by one. The air supply pipes 14 are connected and arranged between the air outlet ends of the air supply pumps 13 and the fixed floating box body 9, and an air supply valve 15 is installed on each air supply pipe 14.

[0034] Among them, the exhaust assembly 004 includes an exhaust pump 16 and an exhaust valve 17. The exhaust pump 16 is installed on the fixed floating box body 9. The intake end of the exhaust pump 16 is communicated with the fixed floating box body 9, and the exhaust valve 17 is installed on the intake end of the exhaust pump 16.

[0035] Specifically, after moving a part of the floating box part 002 below the water surface, the air supply valve 15 in the air supply assembly 003 can be opened, and the air supply pump 13 can be started to introduce gas into the fixed floating box body 9 through the air supply pump 13, so as to increase the air pressure in the fixed floating box body 9. As the pressure in the fixed floating box body 9 increases, the sliding floating box body 10 will move in the direction below the water surface. Through the movement of the sliding floating box body 10, the volume of the floating box part 002 is increased, and by increasing the drainage volume of the floating box part 002, the buoyancy of the floating box part 002 is increased, thereby increasing the load capacity of the ship body. Similarly, by starting the exhaust pump 16, the air in the fixed floating box body 9 can be discharged, and the sliding floating box body 10 can be moved into the fixed floating box body 9.

[0036] Among them, the drainage assembly 005 includes a drainage fixed pipe 18, a drainage sliding pipe 19 and a drainage valve 20. The drainage fixed pipe 18 penetrates and is sealed on the fixed floating box body 9. One end of the drainage sliding pipe 19 is arranged on the funnel-shaped water collecting block 11 through a plurality of positioning blocks. One end of the drainage sliding pipe 19 is located in the water collecting cavity. The other end of the drainage sliding pipe 19 is hermetically sleeved on the drainage fixed pipe 18 in a sliding manner, and the drainage valve 20 is arranged on the drainage fixed pipe 18.

[0037] And a pressure detection sensor 21 is also installed on the fixed floating box body 9 for detecting the pressure in the fixed floating box body 9.

[0038] Specifically, when sliding and adjusting the position of the sliding floating box body 10, when the long-term sliding friction causes the seal to deteriorate and a small amount of water seeps in, and the ship itself cannot be repaired during navigation, the water that seeps into the sliding floating box body 10 will be collected at the water collecting cavity through the funnel-shaped water collecting block 11. At this time, in order to prevent the pressure in the sliding floating box body 10 from decreasing, the air supply pump 13 can be started to continuously introduce gas into the fixed floating box body 9. At this time, the drainage valve 20 in the drainage assembly 005 can be opened, and under the action of pressure, the water accumulated at the water collecting cavity will be discharged from the drainage fixed pipe 18 along the drainage sliding pipe 19.

[0039] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
