Technical Field

[0001] The present invention belongs to the technical field of parachutes, and more specifically, relates to an airdrop device for parachutes. Background Art

[0002] A parachute is a tool that carries people or objects from the air to the ground safely, and is of great significance for the delivery of people or objects.

[0003] At present, airdropping heavy objects into water is a common task at sea, generally used for deep sea exploration or data collection and other tasks. In order to ensure the safety of the equipment being dropped, parachutes are generally used for airdrop. The commonly used airdrop method is to use an overload sensor to sense the overload of entering the water, and then output an electrical signal to stimulate the pyrotechnics to separate the parachute and the dropped equipment (when entering the water, the pyrotechnics explode to release the connection between the parachute and the dropped heavy object).

[0004] However, the above method requires the use of overload sensors and pyrotechnics, resulting in a high cost for the above airdrop method. Summary of the invention

[0005] In view of the above defects or improvement needs of the prior art, the present invention provides an airdrop device for a parachute, the purpose of which is to easily separate the parachute and the dropped equipment when entering the water, thereby effectively reducing the cost of airdrop.

[0009] Optionally, the limiting assembly further includes a shear pin, one end of the shear pin is fixed to the first protrusion, the other end of the shear pin is fixed to the second protrusion, and the shear pin is located directly above the limiting block.

[0010] Optionally, the first plate body and the second plate body are both semicircular plates, and the outer edges of the first plate body and the second plate body are provided with semi-annular baffles, and each of the semi-annular baffles protrudes from two plate surfaces of the first plate body or the second plate body.

[0011] Optionally, the partition is a circular plate, and the outer peripheral wall of the partition is slidably matched with the inner peripheral walls of the two semi-annular baffles.

[0012] Optionally, each of the semi-annular baffles has an inner flange on a side close to the partition, each of the inner flanges is parallel to the first plate body, and the partition plate is located between the first plate body and the inner flange.

In addition, the technical features involved in the various embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0026] Figure 1 Schematic diagram of an explosion of a parachute airdrop device provided by an embodiment of the invention, such as Figure 1 As shown, the airdrop device includes a loading component 1 and a limiting component 2.

[0027] The object-carrying assembly 1 includes a first plate body 11 and a second plate body 12 for carrying the projected device. The outer edge of the first plate body 11 has a first protrusion 111, and the first protrusion 111 has a first groove 1111. The outer edge of the second plate body 12 has a second protrusion 121, and the second protrusion 121 has a second groove 1211. The second groove 1211 is connected to the first groove 1111.

[0028] The limiting assembly 2 includes a limiting block 21, a connecting column 22 and a partition 23, one end of the connecting column 22 is vertically fixed on the partition 23, the other end of the connecting column 22 is connected to the limiting block 21, and the connecting column 22 passes through the first plate body 11 or the second plate body 12, and the limiting block 21 can be slidably inserted in the first groove 1111 and the second groove 1211 to separate from the first protrusion 111 and the second protrusion 121.

[0029] For an airdrop device for a parachute provided in an embodiment of the present invention, before airdropping the device to be airdropped, first, the device to be airdropped is placed on the first plate 11 and the second plate 12 at the same time. Then, multiple connecting ropes of the parachute are connected to the first plate 11 and the second plate 12 respectively. During the airdrop process, the parachute can effectively reduce the falling speed of the device to be airdropped, and at this time, due to the gravity of the partition 23, the limit block 21 will be firmly inserted into the groove of the first protrusion 111 and the second protrusion 121 (see Figure 2 When the bottom surface of the partition 23 first contacts the water surface, the partition 23 will be driven to move upward under the impact of the water, and the partition 23 will drive the connecting column 22 and the limit block 21 to move upward (see Figure 3 ), thereby releasing the connection between the limit block 21 and the first and second protrusions 111, 121, so that the limit block 21 is separated from the first and second protrusions 111, 121, and then the first plate body 11 and the second plate body 12 are separated, so that the launched device can be separated from the first and second plate bodies 11, 12, and the launched device can be released, and finally the separation of the launched device and the parachute is conveniently achieved.

[0030] That is to say, the present invention provides an airdrop device for a parachute, which can conveniently separate the parachute and the dropped equipment when entering the water, can effectively reduce the cost of airdrop, and is safe and reliable.

[0031] In this embodiment, the limiting assembly 2 further includes a shear pin 24 , one end of which is fixed to the first protrusion 111 , the other end of which is fixed to the second protrusion 121 , and the shear pin 24 is located directly above the limiting block 21 .

[0032] In the above embodiment, the shear pin 24 connects the first plate body 11 and the second plate body 12 before the airdrop device enters the water, thereby preventing the first plate body 11 and the second plate body 12 from being accidentally separated and playing a role of insurance.

[0033] Exemplarily, when the bottom surface of the partition 23 first contacts the water surface, the partition 23 will be driven to move upward under the impact of water, and the partition 23 will drive the connecting column 22 and the limit block 21 to move upward. During the upward movement of the limit block 21, the shear pin 24 will be acted on, causing the shear pin 24 to break, thereby releasing the connection between the first plate body 11 and the second plate body 12.

[0034] Figure 4 is a cross-sectional view of a parachute airdrop device provided by an embodiment of the invention, such as Figure 4 As shown, the first plate body 11 and the second plate body 12 are both semicircular plates, and the outer edges of the first plate body 11 and the second plate body 12 have semi-annular baffles 13, and each semi-annular baffle 13 protrudes from the two plate surfaces of the first plate body 11 or the second plate body 12.

[0035] In the above embodiment, the semi-annular baffle 13 can not only serve as a guardrail for the dropped equipment, but also serve as a connecting rope for the parachute.

[0036] Exemplarily, the top of the semi-annular baffle 13 has a plurality of connection holes, through which the connecting ropes of the parachute can be installed.

[0037] In addition, the partition plate 23 is a circular plate, and the outer peripheral wall of the partition plate 23 is slidably matched with the inner peripheral walls of the two semi-annular baffles 13 .

[0038] In the above embodiment, the two semi-annular baffles 13 form a ring, which can guide the upward movement of the partition 23, so that the limiting block 21 can be quickly separated from the first protrusion 111 and the second protrusion 121.

[0039] In this embodiment, each semi-annular baffle 13 has an inner flange 131 on one side close to the partition 23 . Each inner flange 131 is parallel to the first plate body 11 , and the partition 23 is located between the first plate body 11 and the inner flange 131 .

[0040] In the above embodiment, the inner flange 131 can facilitate the insertion of the partition 23 between the plate body and the inner flange 131 when assembling the first plate body 11 and the second plate body 12, prevent the partition 23 from falling, and facilitate the rapid assembly of the limit block 21.

[0041] Exemplarily, the inner flange 131 is located at the bottom of the semi-annular baffle 13 .

[0042] Continuing to refer to 1, the outer edge of the first plate body 11 and the outer edge of the second plate body 12 respectively have a first notch 112 and a second notch 122, the first notch 112 and the second notch 122 are connected, and the first notch 112 and the first groove 1111 are connected, and the second notch 122 and the second groove 1211 are connected, and the connecting column 22 can be movably inserted in the first notch 112 and the second notch 122.

[0043] In the above embodiment, the first notch 112 and the second notch 122 play the role of the connecting column 22 penetrating the first plate body 11 and the second plate body 12 .

[0044] In this embodiment, the first plate body 11 and the second plate body 12, the first protrusion 111 and the second protrusion 121, the first groove 1111 and the second groove 1211, the first notch 112 and the second notch 122 are all symmetrically arranged along the axis of the connecting column 22, and the structures of the first plate body 11 and the second plate body 12, the first protrusion 111 and the second protrusion 121, the first groove 1111 and the second groove 1211, the first notch 112 and the second notch 122 are all the same.

[0045] In this embodiment, the limiting block 21 may be a dovetail block or a square block.

[0046] In addition, the partition 23 is a steel plate or an aluminum plate, so as to increase the structural strength, facilitate load bearing, and prevent breakage during entry into water.

[0047] The following is a brief description of the use of this airdrop device:

[0048] When the bottom surface of the baffle 23 first contacts the water surface, the baffle 23 will be driven upward under the impact of water, and the baffle 23 will drive the connecting column 22 and the limit block 21 to move upward, thereby releasing the connection between the limit block 21 and the first protrusion 111 and the second protrusion 121, so that the limit block 21 is separated from the first protrusion 111 and the second protrusion 121, and then the first plate body 11 and the second plate body 12 are separated, so that the launched equipment can be separated from the first plate body 11 and the second plate body 12, and the launched equipment can be released, and finally the separation of the launched equipment and the parachute is conveniently realized.
