Technical Field

The invention relates to the technical field of air cargo transportation, in particular to an air-drop device.

Background

Air delivery is used for airplane transportation equipment and goods and materials, and is delivered to a designated place from the air. Is a main means for transporting equipment and materials to airborne troops and other troops which fight against the enemy. The air-drop mode is divided into air-drop with umbrella and air-drop without umbrella. At present, the air material transportation develops rapidly, and the intelligent industry rises gradually. The airborne transportation is not only fast, but also has the advantages of reaching complex landforms, special traffic conditions and serious disaster sites, thereby having wide market prospect. In recent years, all types of unmanned aerial vehicles develop very rapidly, the technical maturity is higher and higher, military and civil aviation transportation is gradually popularized, and airdropped materials are diversified. Therefore, the protection approach and effectiveness of material transportation are also receiving more and more attention; especially for the transportation of materials in remote areas with disasters.

The fixed-point throwing of the air drop needs many factors to be considered, such as wind speed, wind direction and multiple conditions of the air drop, for example, an accurate throwing parachute with the application number of CN201720359663.1 is adopted in the existing air drop, the accurate throwing parachute comprises a storage box and parachute wings, the parachute wings are arranged on the top surface of the storage box, mounting seats are fixed on the side surfaces of the storage box, a driving motor is arranged in each mounting seat and connected with a propeller arranged on the side surface of the storage box, at least one image acquisition module is arranged on the bottom surface of the storage box, an electronic compass and a gyroscope sensor which are used for respectively detecting the direction and the horizontal deflection angle of the box body are arranged on the top surface of the storage box, a GPS module, a wireless communication module and an electronic speed regulator are further arranged on the top surface of the storage box, the electronic speed regulator is electrically connected with the driving motor, a microprocessor is arranged in the top, The image acquisition module is electrically connected with the GPS module. This patent simple structure, the operation is convenient, and when the effectual aerial delivery parachute positioning accuracy of having solved was low and descended, great problem with predetermined destination discrepancy has very strong practicality, but rocks great when the aerial delivery case descends, especially the parachute is connected with one point of aerial delivery case, and junction intensity is difficult to guarantee, rocks and is obvious very much, leads to the fan speed governing degree of difficulty big, like the nominal.

Disclosure of Invention

The technical problem to be solved by the invention is as follows: overcomes the defects of the prior art and provides the air-drop device with stable landing.

The technical scheme adopted by the invention for solving the technical problems is as follows: the utility model provides an air-drop device, including parachute and carrier bag, the carrier bag passes through the parachute rope with the parachute and is connected, the parachute rope comprises plural thigh, each side at the carrier bag is connected respectively to each thigh rope, the carrier bag is the square, during the air-drop, the side that faces out the window at first is first side, the side that faces out the window back is the third side, all the other biplanars are the side, the number of the parachute rope strands of first side and third side is greater than the number of the parachute rope strands on the side, the plural number is for being greater than one number, be equivalent to a plurality of meanings.

Furthermore, each umbrella rope is flat and is flatly attached to the carrying bag.

Furthermore, four umbrella ropes are arranged on the first side surface and the third side surface, and two umbrella ropes are arranged on the side surfaces.

Further, carrier bag below is equipped with the layer board, the layer board be dual buffering portion, first layer buffering portion is the honeycomb cardboard, second floor buffering portion is hollow enhancement cardboard strip, the area of honeycomb cardboard is not less than carrier bag area, honeycomb cardboard below pad is equipped with several and is banding hollow enhancement cardboard strip, the concrete structure of honeycomb cardboard and hollow enhancement cardboard strip is prior art, does not do too much repeated here, honeycomb cardboard and hollow enhancement cardboard strip are fixed connection, preferred bonding.

Further, be equipped with the tight pulley on the limit side of layer board, when the air-drop was released, the tight pulley contacted with the window in the air-drop skew, played fine guide effect, the tight pulley can be detachable and layer board is connected, for example bolted connection, buckle connection etc. also can be fixed connection, for example the bonding etc..

Further, the number of the hollow reinforcing paperboard strips is 2 ~ 4, the hollow reinforcing paperboard strips are arranged conventionally and are generally arranged at equal intervals, the width is proper compared with that of the honeycomb paperboard, and the total width is smaller than that of the honeycomb paperboard.

Furthermore, a circle of fixing belt is arranged on the carrier bag and used for reinforcing the carrier bag, the fixing belt is fixedly arranged on the carrier bag, and the fixing mode is usually sewing.

Furthermore, the fixing band is arranged at the joint of the umbrella rope and the bag carrying line, so that the bag carrying is reinforced, and the umbrella rope and the bag carrying line are connected and fixed more.

Furthermore, the side face is parallel to the movement direction of the airplane, the airdrop is generally thrown out from the tail of the airplane when seen from the airplane, the side face is parallel to the flight direction of the airplane when thrown out, namely the side face is the left side and the right side of the airdrop when seen from a person pushing the airdrop on the airplane, the other first side face and the other third side face are the front side and the rear side of the airdrop, the fixed wheels can be attached to the airdrop rail to roll, and after the carrier bag is pushed out, the carrier bag can be shaken left and right to be subjected to the left and right movement of the first side face and the third side face

Further, the material of the carrier bag comprises canvas and industrial cotton, and 232 grass green thin canvas is matched with 80g of finished industrial cotton.

The invention has the beneficial effects that: 1. the front side and the rear side of the carrier bag, namely the first side and the third side, are connected with the parachute line by adopting horizontal lines, so that the swinging of air drop is reduced, and the stable landing of the air drop is ensured.

2. The parachute opening device is simple in structure, scientific and reasonable in design, and better in stability compared with the traditional air-drop, the stress can be effectively balanced through wire connection, and the parachute opening success rate is further improved.
