Description
Technical Field
[0001] The utility model belongs to the field of airdropped water tanks, and particularly relates to an airdropped water tank device for preventing icing. Background Art
[0002] With the development of airborne transportation tools and airdrop technical equipment, the airborne supply capacity and economic benefits will be continuously improved. The airdropped water tank plays an extremely important practical role in wartime operations or rapid water supply in response to sudden disasters. In the prior art, after the airdropped water tank is dropped in a cold area, during the transportation and storage processes of the water tank, icing is likely to occur inside the water tank, making it difficult for the water in the water tank to flow out, thus affecting the normal water supply. Therefore, the airdropped water tank needs to be applicable to an airdrop temperature of minus 50°.
[0003] To ensure normal use under extremely cold temperatures, usually, resistance wire winding tapes are wrapped around both outer ends of the airdropped water tank. After reaching a certain height through a parachute, the water tank drops to a designated position under the action of natural gravity. During the transportation or storage process, the power supply is connected, and the water inside the water tank can be heated to prevent icing. However, directly wrapping the resistance wire winding tapes has the following technical defects: 1. When the water tank is airdropped, it will collide violently with the ground, which may cause the resistance wire winding tapes to be displaced, and even seriously, the resistance wire winding tapes may break away from the water tank, resulting in the inability to be heated normally to prevent icing; 2. The resistance wire winding tapes are wrapped around the outer end positions of the water tank, and the contact area with the water tank surface is small, resulting in uneven heating of the water inside the water tank and low anti-icing efficiency. Content of the Utility Model
[0004] The purpose of the utility model is to overcome the above deficiencies and provide an airdropped water tank device for preventing icing, which ensures the connection stability between the resistance wire winding structure and the water tank body, and ensures the even heating degree and anti-icing efficiency of the water inside the water tank.
[0005] The purpose of the utility model is achieved through the following technical solutions: An airdropped water tank device for preventing icing, comprising a water tank body and a resistance wire winding structure disposed outside the water tank body;
[0006] The water tank body includes a side enclosure part and cover parts disposed at both ends of the side enclosure part. The side enclosure part is connected to the cover parts at both ends to form a closed structure;
[0007] The resistance wire winding structure includes a corner limit closed ring disposed at the connection between the side enclosure part and the cover parts, and a winding connection component covering the outer end face of the side enclosure part. The winding connection component is provided with a power supply interface. The winding connection component includes two radial winding tapes respectively disposed close to the corner limit closed ring. The two radial winding tapes are sleeved on the outer wall of the side enclosure part, and there are a plurality of axial connection winding tapes between the two radial winding tapes. The radial winding tapes are detachably connected to the corresponding corner limit closed rings.
[0008] A further improvement of the present utility model lies in that: the axially connected winding belts are perpendicular to the two radially winding belts, and multiple axially connected winding belts are evenly distributed.
[0009] A further improvement of the present utility model lies in that: the radially winding belt and the corresponding corner limiting closed ring are detachably connected by a zipper.
[0010] A further improvement of the present utility model lies in that: the radially winding belt and the corresponding corner limiting closed ring are detachably connected by a buckle.
[0011] A further improvement of the present utility model lies in that: the corner limiting closed ring includes an end face portion in contact with the edge of the cover portion and a side face portion in contact with the edge of the side end enclosing portion, and a smooth transition is provided between the end face portion and the side face portion.

The two radial winding tapes 221 are sleeved on the outer wall of the side enclosure part 11, and there are a plurality of axial connection winding tapes 222 between the two radial winding tapes 221. The radial winding tape 221 and the corresponding corner limit closing ring 21 are detachably connected.
[0029] The resistance wire winding structure 2 in the present utility model includes a corner limit closing ring 21 and a winding connection assembly 22. The winding connection assembly 22 is fixedly limited between the two corner limit closing rings 21. Through the cooperation of the corner limit closing ring 21 and the water tank body 1, the axial limit fixation of the winding connection assembly 22 on the side enclosure part 11 of the water tank body 1 is realized. And the corner limit closing ring 21 and the radial winding tape 221 can also be radially fixed on the water tank body 1, thereby ensuring the connection stability between the resistance wire winding structure 2 and the water tank body 1.
[0030] In the present utility model, axial connection winding tapes 222 are arranged between the radial winding tapes 221, greatly increasing the contact area between the resistance wire winding structure 2 and the water tank body 1, thereby ensuring the even heating degree of the water inside the water tank and the anti-icing effect.
[0031] On the basis of this embodiment, the axial connection winding tapes 222 are arranged perpendicular to the two radial winding tapes 221, and the plurality of axial connection winding tapes 222 are evenly distributed.
[0032] On the basis of this embodiment, the number of the axial connection winding tapes 222 is 2, the axial connection winding tapes 222 are of an X-shaped structure, and the two axial connection winding tapes 222 are correspondingly arranged on the outer end surface of the side enclosure part 11.
[0033] It should be noted that the axial connection winding tape 222 is not limited to Figure 2 the X-shaped structure in, and can also be a straight bar structure perpendicular to the radial winding tape 221. The specific structure is not limited. The axial connection winding tape 222 not only plays a role in connecting the two radial winding tapes 221, but also increases the heating area inside the water tank body 1.
