[0002] In emergency rescue, disaster relief or wartime, food, daily necessities and oil and water resources need to be airdropped at high altitudes in the existing technology. It is difficult to airdrop liquid oil and water materials. Therefore, a high-altitude emergency airdrop finished oil and water sac is needed to meet the needs of high-altitude emergency airdrop finished oil and water.

[0003] In the prior art, liquid is filled into the capsule and sealed. Then, during the airdrop process, the capsule is easily affected by the airflow, causing the capsule to flip over. At the moment of contact with the ground, it is subjected to the reverse impact force of the ground, which can easily cause the capsule to bounce and roll over, resulting in multiple collisions and damage to the capsule.

[0004] Currently, no effective solution has been proposed for the problems in the related technologies. Utility Model Content

[0005] In view of the problems in the related technology, the utility model proposes a high-altitude emergency airdrop finished oil water sac body to overcome the above technical problems existing in the existing related technology.

[0006] In order to solve the above technical problems, the utility model is achieved through the following technical solutions:

[0008] Furthermore, a cross fixing frame is fixedly connected inside the oil-water pipe, a threaded rod is threadedly connected inside the cross fixing frame, and a rotating handle is fixedly connected to the top end of the threaded rod.

[0009] Furthermore, the bottom end of the oil-water pipe fits the sealing disk, the top end of the sealing disk is fixedly connected with a convex block, and the top end of the convex block is fixedly connected to the bottom end of the threaded rod.

[0010] Furthermore, a through hole is opened at the top of the wrapping layer, and the interior of the through hole fits with the outer surface of the oil-water pipe.

[0011] Furthermore, a sealing ring is sleeved on the bottom end of the flange, and mounting holes are provided inside the flange and the sealing ring.

[0012] Furthermore, a threaded hole is provided at the top of the wrapping layer, and a fixing bolt is connected to the inner thread of the threaded hole, and the outer surface of the fixing bolt is slidably arranged with the inner wall of the mounting hole.

[0013] Furthermore, a spring washer is sleeved on the outer surface of the fixing bolt, a flat washer is fitted on the bottom end of the spring washer, and the bottom end of the flat washer is fixedly connected to the top end of the flange.

[0014] The utility model has the following beneficial effects:

[0015] 1. The utility model unscrews the pipe cap, then pours water or oil from one end of the oil-water pipe into the inner capsule, and seals one end of the oil-water pipe with the pipe cap again. Since the outer capsule and the inner capsule have excellent properties such as resistance to strong ultraviolet radiation, resistance to high and low temperature cycles, resistance to chemical corrosion, strong water and oil repellency, good mechanical properties, and anti-permeability, water or oil penetration can be avoided, and water or oil residue can be avoided inside the inner capsule. When the oil-water capsule is airdropped, the bottom end of the oil-water capsule impacts the ground. Since the wrapping layer is made of ultra-high molecular weight It is made of polyethylene fiber fabric and has high tensile strength, tear strength, bursting strength and excellent anti-puncture performance. It can prevent the wrapping layer from rupturing when it collides with sharp objects on the ground. The outer net bag and the inner net bag are sewn into a net bag shape with high-strength webbing, which is mainly used to fix the buffer pad and disperse the impact force. The buffer pad is made of highly elastic material. On the one hand, it plays a buffering role when thrown to the ground to prevent local stress concentration; on the other hand, it prevents the sac from being punctured by sharp objects on the ground, so it is not easy to cause damage to the oil-water sac.

[0016] 2. The utility model drives the threaded rod to rotate by rotating the handle, and cooperates with the internal thread of the cross fixing frame to make it move up and down. Since the bottom end of the threaded rod is fixedly connected with a protrusion, the bottom end of the protrusion is fixedly connected to the sealing disk, and then the movement of the threaded rod can drive the protrusion and the sealing disk to move, so that the sealing disk and one end of the oil-water pipe can be fitted or released, and one end of the oil-water pipe can be opened or closed, which further improves the sealing performance of the oil-water bag.
