[0021] In order to make the purpose, technical scheme and advantages of the present application more clear, the present application is further described in detail below in combination with the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application, and are not used to limit the present application.

[0022] The present application provides a water-enterable separation umbrella cabin, the structure of which is as shown in Figure 1As shown in the drawings, the water-enterable separation parachute cabin comprises a cabin body 1, a cabin bottom plate 2, a screw joint structure 3 and an axial flow runner assembly 4. The cabin body 1 is fixedly connected with the canopy rope of a parachute, the cabin bottom plate 2 is fixedly connected with an air-dropped heavy object, the screw joint structure 3 is fixedly arranged between the cabin body 1 and the cabin bottom plate 2, and the cabin body 1 is screwed with the cabin bottom plate 2 through the screw joint structure 3. The axial flow runner assembly 4 is fixedly arranged on the cabin body 1 or the cabin bottom plate 2, and the rotation center axis of the axial flow runner assembly 4 coincides with the axial direction of the cabin body and the cabin bottom plate.

[0023] After the axial flow runner assembly 4 enters water, the cabin body 1 and the cabin bottom plate 2 are relatively rotated due to water impact, so that the cabin body 1 and the cabin bottom plate 2 are separated from the screw joint state.

[0024] When the air-dropped heavy object enters water at a high speed, the axial flow runner assembly 4 is impacted by water to make the cabin body 1 and the cabin bottom plate 2 relatively rotate, so that the cabin body 1 and the cabin bottom plate 2 are quickly separated from the screw joint state, and the cabin bottom plate 2 continuously falls under the action of inertia while the cabin body 1 is slowed down by the parachute, so that the cabin body 1 and the cabin bottom plate 2 are quickly separated, thereby realizing the separation of the object and the parachute. The separation mode is a pure mechanical separation, and the reliability is high.

[0025] As shown in Figure 2 and Figure 3 respectively are the structural schematic diagrams of the cabin body and the cabin bottom plate in the embodiment of the present application. As a preferred embodiment, the screw joint structure 3 comprises a plurality of clamping grooves 31 fixedly arranged at the bottom of the cabin body 1 and a plurality of protrusions 32 fixedly arranged on the cabin bottom plate 2 and corresponding to the clamping grooves 31, and the protrusions 32 are movably inserted into the corresponding clamping grooves 31. Specifically, in order to facilitate the processing and production, the clamping grooves 31 are integrally formed with the cabin body 1, and the protrusions 32 are integrally formed with the cabin bottom plate 2.

[0026] It can be understood that when the cabin body 1 and the cabin bottom plate 2 relatively rotate, the protrusions 32 can be separated from the corresponding clamping grooves 31 to release the constraint, so that the cabin body 1 and the cabin bottom plate 2 are quickly separated.

[0027] It should be noted that the screw joint structure 3 is provided with the clamping grooves 31 and the protrusions 32 only as a preferred embodiment in this embodiment, and in other embodiments, the screw joint structure 3 can also comprise an internal thread formed in the inner wall of the bottom of the cabin body 1 and an external thread formed on the top outer side of the cabin bottom plate 2, and the internal thread can be engaged with the external thread. When the cabin body 1 and the cabin bottom plate 2 relatively rotate, the internal thread and the external thread are disengaged from the engagement state, so that the cabin body 1 and the cabin bottom plate 2 are separated.

[0028] Please continue to refer to Figure 2 As a preferred embodiment, the axial flow runner assembly 4 comprises a plurality of blades 40 which are circumferentially distributed on the outside of the cabin body 1 or the cabin floor. As a specific embodiment, the blades 40 are plastic blades or wooden blades, which can reduce the weight of the umbrella cabin.

[0029] It can be understood that the circumferential distribution of the blades 40 on the outside of the cabin body 1 or the cabin floor 2 can maximize the torque received by the cabin body 1 or the cabin floor 2 when the axial flow runner assembly 4 rotates, so that the cabin body 1 and the cabin floor 2 can be quickly separated in the shortest time.

[0030] In this embodiment, a plurality of blades 40 are circumferentially and uniformly fixed on the outer side wall of the cabin body 1. Specifically, the blades 40 are wing plates inclined to the vertical plane and fixed on the outer side wall of the cabin body 1.

[0031] As a preferred embodiment, considering that the wing plate will be subjected to a certain force when falling in the air and entering the water, in order to avoid the airflow force on the wing plate being too large in the air and causing the cabin body 1 and the cabin floor 2 to separate in the air, the angle between the wing plate and the vertical plane is 5°-10°, and the number of wing plates is 16.

[0032] As a preferred embodiment, the water-entering separable umbrella cabin further comprises a plurality of umbrella connecting supports 5 fixedly arranged on the inner wall of the top of the cabin body 1, for fixedly connecting with the parachute rope of the parachute; the umbrella connecting support 5 comprises two oppositely arranged supporting seats 51 and a fixed rod 52 fixedly connected between the two supporting seats 51.

[0033] As a preferred embodiment, the density of the cabin body 1 and the cabin floor 2 is less than the density of water. Specifically, the cabin body 1 and the cabin floor 2 are plastic cabin body and plastic cabin floor, respectively.

[0034] It can be understood that the density of the cabin body 1 and the cabin floor 2 is less than the density of water, which can make the cabin body 1 and the cabin floor 2 float in water, so as to facilitate the search for the air-dropped heavy object falling into the water.

[0035] In order to facilitate the understanding of the present application, the following will be combined with Figures 1-3 The working principle of the present scheme will be described in detail:

[0036] When the parachute cabin enters water at a faster speed, the axial flow runner assembly 4 is subjected to a water impact torque at the moment of entering water, which is transmitted to the cabin body 1 to drive the cabin body 1 to rotate, while the cabin bottom plate 2 only has a falling speed under the action of inertia, the water impact torque overcomes the friction between the clamping groove 31 and the protruding block 32, so that the clamping groove 31 rotates relative to the protruding block 32 (that is, the cabin body 1 rotates relative to the cabin bottom plate 2) to make the protruding block 32 be released from the corresponding clamping groove 31, at this time, the cabin bottom plate 2 continues to fall due to inertia, while the cabin body 1 is slowed down by the parachute, so that the cabin body 1 and the cabin bottom plate 2 are separated, that is, the object-parachute separation is realized.

[0037] The water-entering separable parachute cabin has the following beneficial effects:

[0038] When the parachute cabin enters water at a faster speed, the axial flow runner assembly 4 is subjected to a water impact torque at the moment of entering water, which is transmitted to the cabin body 1 to drive the cabin body 1 to rotate, while the cabin bottom plate 2 only has a falling speed under the action of inertia, the water impact torque overcomes the friction between the clamping groove 31 and the protruding block 32, so that the clamping groove 31 rotates relative to the protruding block 32 (that is, the cabin body 1 rotates relative to the cabin bottom plate 2) to make the protruding block 32 be released from the corresponding clamping groove 31, at this time, the cabin bottom plate 2 continues to fall due to inertia, while the cabin body 1 is slowed down by the parachute, so that the cabin body 1 and the cabin bottom plate 2 are separated, that is, the object-parachute separation is realized.

[0039] The specific embodiments of the application described above do not constitute a limitation on the scope of protection of the application. Any various other corresponding changes and modifications made according to the technical concept of the application shall be included in the scope of protection of the claims of the application.
