Lifesaving backpack for marsh

Abstract

The invention relates to the field of lifesaving equipment, and discloses a lifesaving backpack for a marsh, which comprises a base, arc-shaped cavities are symmetrically formed in the four sides in the base, tile-shaped plates are slidably arranged in the arc-shaped cavities, side plates are fixedly arranged on the end faces, extending out of the base, of the tile-shaped plates, and through cavities are formed in the side plates on the front side, the rear side, the left side and the right side. The inner lower wall of the through cavity is fixedly connected with an inner container. According to the lifesaving knapsack for the marsh, unlocking of the side plates and the base is completed by rotating the rotating wheels, so that the knapsack can be quickly and flatly laid on the ground, the process is quick, operation is easy, the knapsack can be quickly laid in the marsh at the first time, the escape probability is greatly increased, then the liner is inflated, the surface area of the liner is increased, and then the liner is placed under the body; the body is driven to move by means of force, the defect that the body is difficult to move after falling into marsh is overcome, the time needed for escaping is shortened, and finally the base is taken back and reinstalled into a backpack for use next time.

Description

technical field [0001] The invention relates to the technical field of lifesaving equipment, in particular to a lifesaving backpack for swamps. Background technique [0002] The swamp is composed of fine-grained soil with a very high water content. The whole is soft, and creatures or objects standing on it are prone to subsidence. At this time, if they struggle violently, it will have the opposite effect, sinking deeper and deeper, and self-rescue after falling into the swamp The methods are similar, but need to increase the contact area with the swamp, slowly push the body with hands or feet to loosen the trapped quicksand, and finally slide to the hard ground. [0003] Some self-rescue methods are to sprinkle quicklime into the swamp, and use the reaction between the quicklime and the swamp to escape from the hardened swamp. The method is to increase the force-receiving area, but the body area is small, and it is slightly difficult to do any movement from the swamp withou...

AI Technical Summary

Problems solved by technology

[0004] The present invention provides a lifesaving backpack for swamps, which is easy to operate and can be deformed without too many movements. At the same time, the probability of getting out of trouble is increased by forming a larger contact area with the swamp, and it can be out of trouble with the help of an inflated inner tank. , to solve the shortcomings of the small size of the body or the size of the clothes, which leads to the failure of getting out of trouble, and at the same time, people can't take advantage of the force in the swamp, which leads to difficulty in moving, which leads to the situation of getting deeper and deeper
