Description

Technical Field

[0001] The utility model relates to the technical field of inflatable life raft components, and more particularly to an inflatable life raft balancing water bag regulating device. Background Art

[0002] An inflatable life raft is a lifesaving device made of rubber. It's normally deflated and folded, housed in a fiberglass container, typically a cylinder with hemispherical ends. When deployed in an emergency, the raft automatically inflates by pulling the valve on its onboard gas cylinder (usually containing CO2). This inflated life raft provides the buoyancy and space to carry people in distress or drowning, saving lives. Existing inflatable life rafts come in two types: mechanically lowered and cast-in-place. Mechanically lowered inflatable life rafts are already inflated on deck and then cast into the water.

[0003] A common inflatable life raft mainly consists of four parts: the raft body (upper and lower buoyant tires), the canopy poles, the tent and the raft bottom. Among them, there are usually balancing water bags at the edges of the raft bottom. Each bag has 3 to 4 circular leakage holes. When the life raft floats normally on the sea, the balancing water bags are filled with seawater to increase the stability, resistance and balance of the raft body. The existing balancing water bags have the following problems in actual use: first, the position of the balancing water bags is fixed and cannot be adjusted. The required balancing position cannot be adjusted according to the actual sea surface conditions, resulting in insufficient balance stability; second, when the life raft needs to move forward or be towed for rescue, the seawater in the balancing water bags is released slowly, and the seawater in the bags cannot be discharged quickly and in time, which increases the resistance of the life raft when moving forward and affects the rescue speed. Utility Model Content

[0004] The purpose of the utility model is to provide an inflatable life raft balancing water bag adjustment device, which can, on the one hand, adjust the balancing water bags around the raft bottom by moving them inward and outward, and at the same time, can quickly release water from the balancing water bags, so as to quickly reduce the forward resistance and speed up the rescue when the life raft needs to move forward or be towed for rescue.

[0005] In order to achieve the above purpose, the technical solution adopted by the present utility model is as follows:

[0006] The raft is provided with a plurality of balancing water bags, each of which is provided with a plurality of balancing water bags, each of which is provided with a plurality of balancing water bags, each of which is provided with a plurality of balancing water bags having a plurality of balancing water bags disposed on the raft.

[0007] As a further optimization of this solution, the steering cylinder is fixed on the outer side of the fixed seat, the upper surface of the fixed seat is fixed to the middle position of the lower surface of the raft bottom by studs on all sides, a circular blind groove is provided on the lower side of the fixed seat, an adjustment groove is provided at the center of the circular blind groove, and a movable seat is installed inside the adjustment groove, the upper end of the movable seat is an anti-slip chuck and the middle section is a column with a radius smaller than the adjustment groove, and the lower end of the movable seat is connected to the inflection point of the polygonal frame through a number of outward connecting rods.

[0008] As a further optimization of this solution, the anti-slip chuck of the movable seat does not contact the column when it moves outward to the maximum position, and the movable seat column is located in the inner area of ​​the adjustment slot.

[0009] As a further optimization of this solution, the pull rope is in a loose state when not in use and is prevented from slipping into the water by a limiting sleeve.

[0010] Compared with the existing technology, the beneficial effects of the utility model are as follows:

[0011] The utility model is provided with a polygonal frame, a connecting rod, a movable seat and a fixed seat, and the balancing water bag is installed on the polygonal frame. The balancing water bag is adjusted by moving the polygonal frame. When the inflatable life raft is floating, the position of the balancing water bag is adjusted as required according to the actual sea surface conditions, thereby ensuring the balance stability of the raft and the personal safety of the people to be rescued.

[0012] The utility model provides structures such as a steering cylinder, a pull rope and a limiting sleeve, so that the lower part of the balancing water bag can be pulled up. When the inflatable life raft needs to move forward or be towed for rescue, all the balancing water bags can be quickly released to quickly reduce the forward resistance and speed up the rescue.

[0018] In order to make the technical means, creative features, objectives and effects of the utility model easier to understand, the utility model is further explained below with reference to specific illustrations.

[0019] In order to solve the problem that the existing balance water bag is fixed in position and cannot be adjusted, the balance position cannot be adjusted according to the actual sea surface conditions, resulting in poor balance stability, and when the life raft needs to move forward or be towed for rescue, the seawater in the balance water bag is released slowly, and the seawater in the bag cannot be discharged quickly and in time, which increases the resistance of the life raft when it moves forward and affects the rescue speed. Figure 1 As shown, the present application includes upper and lower buoyant tires 1, wherein a raft bottom 8 is provided inside the upper and lower buoyant tires 1, a raft boarding platform 4 is provided on the side of the upper and lower buoyant tires 1, and a tent 2 is connected to the upper and lower buoyant tires 1 through tent poles, and an entrance 3 is provided on the surface of the tent 2;

[0020] like Figure 2As shown, a polygonal frame 14 is provided below the upper and lower floating tires 1, and a plurality of balancing water bags 5 are arranged around and spaced on the polygonal frame 14, wherein the upper end of the opening side of the outer side of the balancing water bag 5 is sleeved on the border of the polygonal frame 14, and an L-shaped adjustment bracket 9 is connected to the side of the polygonal frame 14 near the entrance and exit 3, and a hand sleeve 6 is provided at the middle position above the L-shaped adjustment bracket 9. A connecting plate 10 is provided outwardly on one side of the L-shaped adjustment bracket 9, and a through hole is opened on the surface of the connecting plate 10 and a pull rope 12 passes through the through hole. A pull rod 7 is fixed to the upper end of the pull rope 12 and a limiting sleeve 11 is sleeved on the outer periphery of the pull rope 12 between the pull rod 7 and the connecting plate 10, and the lower end of the pull rope 12 is inserted into the interior of the steering cylinder 13 below and the lower end is forked and connected to the middle position of the bottom of the plurality of balancing water bags 5;

[0021] like Figure 3 As shown, the steering cylinder 13 is fixed to the outer side of the fixing seat 16. The upper surface of the fixing seat 16 is fixed to the middle position of the lower surface of the raft bottom 8 by studs 17 on all sides. A circular blind groove is opened on the lower side of the fixing seat 16, and an adjustment slot 19 is opened at the center of the circular blind groove. A movable seat 18 is installed inside the adjustment slot 19. The upper end of the movable seat 18 is an anti-slip chuck and the middle section is a column with a radius smaller than the adjustment slot 19. The lower end of the movable seat 18 is connected to the inflection point of the polygonal frame 14 through a plurality of outward connecting rods 15.

[0022] Specifically, such as Figure 4 As shown, after the mechanically suspended inflatable life raft is inflated, the fixing seat 16 of the present application is fixed at the center position of the lower surface of the raft bottom 8 by screwing in the studs, and all the adjustment device components are connected. After being thrown into the water, all the balancing water bags are quickly filled with water through the openings. When the pull rope 12 is not working, it is in a loose state and is prevented from sliding into the water by the limiting sleeve 11. The rescued person on the life raft can manipulate the L-shaped adjustment bracket to move in all directions through the hand grip 6, thereby driving the polygonal frame 14 to move, and finally driving the surrounding balancing water bags 5 to be reasonably adjusted according to the floating situation, changing the positions of different balance points, and ensuring the floating stability of the life raft. The moving area of ​​the balancing water bag 5 is limited by the adjustment slot 19 of the fixing seat 16 to prevent the balancing water bag 5 from excessive displacement;

[0023] In another specific case, when the inflatable life raft needs to move forward or be towed for rescue, the people to be rescued on the life raft can directly pull the pull rod 7 upwards to drive the pull rope 12 to move, and pull the lower ends of all the balancing water bags 5 inward from the center position of the lower end of the steering cylinder 13. Since the upper end of the outer side of the balancing water bag 5 is mounted on the edge of the polygonal frame 14, the balancing water bag 5 will rotate inward with the edge as the center, and then pour out the seawater inside, and quickly release the water from all the balancing water bags 5, quickly reducing the forward resistance and speeding up the rescue.
