Description

Technical Field

[0001] This utility model relates to the field of oxygen supply technology, and in particular to an oxygen supply system and limiting structure for a rescue ship. Background Technology

[0002] In maritime rescue operations, the stability and reliability of the oxygen supply system on rescue vessels are crucial, as they are key pieces of equipment. Traditional rescue vessel oxygen supply systems typically expose oxygen tanks directly to the elements without proper securing or protection. During navigation, the hull can sway due to waves and wind, causing oxygen tanks to easily shift or collide with objects. This not only affects the stability of the oxygen supply but can also create safety hazards. Furthermore, replacing oxygen tanks in traditional systems is cumbersome and inefficient, hindering rapid response to rescue needs. Utility Model Content

[0003] The purpose of this utility model is to solve the shortcomings of the existing technology, such as oxygen tanks being exposed to the outside without good fixing and protection measures, oxygen tanks being prone to displacement or collision, and the operation of replacing oxygen tanks being cumbersome and inefficient. Therefore, a rescue ship oxygen supply system and limiting structure are proposed.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] An oxygen supply system for a rescue boat includes a protective box with an open top and a mounting hole on one side of the top. A rotating shaft is rotatably connected to the bottom inner wall of the mounting hole, and a side cover plate is fixedly fitted onto the outer wall of the rotating shaft. A top cover plate is hinged to the top of the protective box, and a vertical groove is provided on one side of the protective box. A braking component for braking the top cover plate is provided inside the vertical groove.

[0006] An oxygen cylinder is located inside a protective box, and the bottom of the protective box is provided with a support assembly for supporting the oxygen cylinder.

[0007] In one possible design, the braking assembly includes a U-shaped insert that slides through the inner wall of one side of the vertical groove, one end of the U-shaped insert extending into the interior of the mounting hole, and two symmetrically arranged first tension springs fixedly connected between one side of the U-shaped insert and one side of the inner wall of the vertical groove. An L-shaped groove is provided on one side of the upper cover plate, and the L-shaped groove engages with the U-shaped insert.

[0008] In one possible design, the support assembly includes a base plate slidably connected to the inner wall of the protective box, with four springs symmetrically connected in pairs between the bottom of the base plate and the bottom inner wall of the protective box.

[0009] In one possible design, the inner wall of the top cover is provided with a rubber pad, and a first handle is fixedly connected to one side of the top cover.

[0010] In one possible design, a clearance hole is provided on one side of the side cover plate, which is used in conjunction with a U-shaped insert rod, and a second handle is fixedly connected to one side of the side cover plate.

[0011] A limiting structure for limiting the oxygen supply system of the rescue boat, comprising two symmetrically arranged sliding vertical rods and two symmetrically arranged strip grooves. The two strip grooves are respectively opened on the top two sides of the protective box. The sliding vertical rods are slidably connected to the inside of the strip grooves. The bottom of the sliding vertical rods and the bottom inner wall of the strip grooves are fixedly connected by the same compression spring.

[0012] In one possible design, two symmetrically arranged transverse holes are opened on one side of the inner wall of the strip groove. A sliding block slides through the inside of the transverse hole. A clamping plate is fixedly connected to one side of the sliding block. The clamping plate is in contact with the oxygen tank. Two symmetrically arranged second tension springs are fixedly connected between one side of the clamping plate and one side of the inner wall of the protective box.

[0013] In one possible design, a rectangular hole is provided on one side of the sliding block, two symmetrically arranged triangular blocks are fixedly connected to one side of the sliding vertical rod, and two symmetrically arranged side grooves are provided on the inner wall of one side of the strip groove. The side grooves are used to accommodate the triangular blocks, and the inclined surfaces of the triangular blocks are used in conjunction with the rectangular hole.

[0014] In this application, when in use, the protective box is fixed inside the cabin. Normally, when the hull shakes, the oxygen tank will move up and down slightly. The bottom plate moves up under the elastic force of the spring, so that the bottom plate is always close to the bottom of the oxygen tank. The friction between the oxygen tank and the clamping plate can achieve cushioning, and the rubber pad can protect the oxygen tank.

[0015] During normal oxygen supply, the side cover can be rotated open using the second handle to supply oxygen to the user using the oxygen tank, thus preventing the top cover from opening and ensuring the stability of the oxygen tank during use. When the oxygen tank needs to be replaced, the U-shaped rod can be moved laterally from inside the mounting hole with the side cover open. The U-shaped rod stretches the first tension spring and moves out from inside the L-shaped groove, releasing the braking state of the top cover, which can then be flipped upwards to open.

[0016] At the same time, the top cover plate no longer presses against the two sliding vertical rods. The sliding vertical rods move upward under the elastic force of the compression spring. The sliding vertical rods drive multiple triangular blocks to move upward. At this time, the triangular blocks are no longer located inside the rectangular hole, and the sliding blocks are no longer pressed. At this time, the sliding blocks and the clamping plates move under the tension of the second tension spring. The two clamping plates move away from each other and no longer clamp the oxygen tank. The oxygen tank can be replaced, which is convenient to use.

[0017] Beneficial effects: Improved stability: The protective box design secures the oxygen tanks inside the cabin, effectively preventing displacement and collisions during hull movement. Simultaneously, the base plate, under the elasticity of springs, remains firmly attached to the bottom of the oxygen tanks, further enhancing stability.

[0018] Protecting the oxygen cylinder: The rubber pads effectively protect the oxygen cylinder, reducing the risk of damage from impacts. Furthermore, the friction between the oxygen cylinder and the clamping plate provides cushioning, further protecting the cylinder.

[0019] Facilitates oxygen cylinder replacement: The design of the braking assembly and limiting structure allows for easy release of the brake on the upper cover and opening of the cover when oxygen cylinder replacement is needed. Simultaneously, the clamping plates move apart under the tension of the second spring, no longer clamping the oxygen cylinder, thus facilitating the replacement operation. This design not only improves replacement efficiency but also ensures safety during the replacement process.

[0020] Easy to operate: The side cover can be easily opened by rotating the second handle to enable oxygen supply. The top cover remains closed, ensuring the stability of the oxygen cylinder during use. This design makes operation simpler and faster, improving rescue efficiency. Attached Figure Description

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0028] Example 1; Refer to Figure 1-5 An oxygen supply system includes: a protective box 1, the top of which is open; a mounting hole 10 is formed on the top side of the protective box 1; a rotating shaft 16 is rotatably connected to the bottom inner wall of the mounting hole 10; a side cover plate 2 is fixedly sleeved on the outer wall of the rotating shaft 16; a top cover plate 3 is hinged to the top of the protective box 1; a vertical groove 17 is formed on one side of the protective box 1; a braking assembly for braking the top cover plate 3 is provided inside the vertical groove 17; the braking assembly includes a U-shaped rod 11 that slides through the inner wall of one side of the vertical groove 17; one end of the U-shaped rod 11 extends into the mounting hole 10; and symmetrically arranged... The upper cover 3 has two first tension springs 15 and an L-shaped groove 6 on one side. The L-shaped groove 6 engages with the U-shaped rod 11. During normal oxygen supply, the side cover 2 can be rotated open using the second handle 5 to supply oxygen to the user using the oxygen tank 8. Thus, the upper cover 3 will not open, ensuring the stability of the oxygen tank 8 during use. When the oxygen tank 8 needs to be replaced, the U-shaped rod 11 can be moved laterally from the inside of the mounting hole 10 while the side cover 2 is open. The U-shaped rod 11 stretches the first tension spring 15 and moves out from the inside of the L-shaped groove 6. At this time, the braking state of the upper cover 3 can be released, and the upper cover 3 can be flipped up and opened.

[0029] Oxygen tank 8 is located inside the protective box 1. The bottom of the protective box 1 is provided with a support assembly for supporting the oxygen tank 8. The support assembly includes a base plate 13 that is slidably connected to the inner wall of the protective box 1. Four springs 14 are fixedly connected in pairs between the bottom of the base plate 13 and the bottom inner wall of the protective box 1, which fixes the protective box 1 inside the cabin. Normally, when the hull shakes, the oxygen tank 8 will move up and down slightly. The base plate 13 moves up under the elastic force of the springs 14, so that the base plate 13 always keeps close to the bottom of the oxygen tank 8. The friction between the oxygen tank 8 and the clamping plate 21 can achieve cushioning, and the rubber pad 7 can protect the oxygen tank 8.

[0030] A limiting structure for limiting the oxygen supply system of the rescue boat, comprising two symmetrically arranged sliding vertical rods 12 and two symmetrically arranged strip grooves 18. The two strip grooves 18 are respectively opened on the top sides of the protective box 1. The sliding vertical rods 12 are slidably connected to the inside of the strip grooves 18. The bottom of the sliding vertical rods 12 and the bottom inner wall of the strip groove 18 are fixedly connected by the same compression spring 24. Two symmetrically arranged horizontal holes 19 are opened on one side of the inner wall of the strip groove 18. A sliding block 20 slides through the inside of the horizontal hole 19. A clamping plate 21 is fixedly connected to one side of the sliding block 20. The clamping plate 21 is in contact with the oxygen tank 8. Two symmetrically arranged second tension springs 22 are fixedly connected between one side of the clamping plate 21 and one side of the inner wall of the protective box 1. A rectangular hole 27 is provided on the side. Two symmetrically arranged triangular blocks 23 are fixedly connected to one side of the sliding vertical rod 12. Two symmetrically arranged side grooves 26 are provided on the inner wall of one side of the strip groove 18. The side grooves 26 are used to accommodate the triangular blocks 23. The inclined surface of the triangular blocks 23 cooperates with the rectangular hole 27. At the same time, the upper cover plate 3 no longer presses the two sliding vertical rods 12. The sliding vertical rods 12 move upward under the elastic force of the compression spring 24. The sliding vertical rods 12 drive the multiple triangular blocks 23 to move upward. At this time, the triangular blocks 23 are no longer located inside the rectangular hole 27. As a result, the sliding block 20 is no longer pressed. At this time, the sliding block 20 and the clamping plate 21 move under the tension of the second tension spring 22. The two clamping plates 21 move away from each other and no longer clamp the oxygen tank 8. The oxygen tank 8 can be replaced, which is convenient to use.

[0031] This application can be used in the field of rescue vessels, and can also be applied to other technical fields.
