DETAILED DESCRIPTION

[0033] like Figure 1-5 As shown, this embodiment includes a base plate 1, a first reel 2, a second reel 3, a support plate 4, a swing arm, a first rope reel, and a second rope reel.

[0034] One end of the bottom plate 1 is arranged at the edge of the hull, and the other end of the bottom plate 1 is provided with a notch 1a, and vertical plates 1b are provided on both sides of the notch 1a and stand on the bottom plate 1, and a supporting plate 1c is provided at the bottom of the notch 1a, and the supporting plate 1c is parallel to the bottom plate 1. In other embodiments, a certain part of the deck of the hull can also be directly set to the structure of the bottom plate 1.

[0035] The first reel 2 is arranged at the end of the vertical plate 1b facing the sea surface, and the second reel 3 is arranged at the end of the vertical plate 1b facing the hull. Of course, in order to realize the basic function, the first reel 2 and the second reel 3 should be higher than the highest height of the support plate 4 being pulled up. The first reel 2 and the second reel 3 are arranged on both vertical plates 1b, and the first reel 2 and the second reel 3 on the two vertical plates 1b are symmetrical to each other. In this embodiment, the first reel 2 and the second reel 3 are driven by the driving motor 6 to rotate forward and reverse, and the driving motor 6 is fixed on the vertical plate 1b.

[0036] A frame 4a for mounting the unmanned aerial vehicle is provided on the support plate 4, and a first axis, a second axis and a third axis are sequentially provided on two sides of the support plate 4 from the sea surface to the hull direction.

[0037] The swing arm includes a first swing arm 5a, a second swing arm 5b and a third swing arm 5c. The first swing arm 5a, the second swing arm 5b and the third swing arm 5c are of equal length and parallel to each other. One end of the first swing arm 5a is hinged to the end of the first shaft, one end of the second swing arm 5b is hinged to the end of the second shaft, and one end of the third swing arm 5c is hinged to the end of the third shaft. The other ends of the first swing arm 5a, the second swing arm 5b and the third swing arm 5c are all hinged to the side wall of the notch 1a. Of course, if the hinge position of the other ends of the first swing arm 5a, the second swing arm 5b and the third swing arm 5c is higher, they can also be hinged to the vertical plate 1b according to actual conditions. The vertical plate 1b should be understood as an extension of the side wall of the notch 1a.

[0038] The first swing arm 5a, the second swing arm 5b and the third swing arm 5c swing around the hinge to horizontally rotate the support plate 4 on the support plate 1c to the bottom of the support plate 1c. To achieve this function, it is only necessary to make the distance between the two adjacent swing arms and the base plate 1 hinged greater than the length of the swing arm, but in this way, the swing amplitude of the swing arm will be smaller, which is not applicable to longer unmanned aerial vehicles. In order to overcome this problem, the present embodiment sets the distance between the two adjacent swing arms and the base plate 1 hinged to be less than the length of the swing arm, and then sets the first axis to be longer than the second axis, and the second axis to be longer than the third axis, so that the second swing arm 5b can pass through the gap between the first swing arm 5a and the side wall of the support plate 4 when swinging, and the third swing arm 5c can pass through the gap between the second swing arm 5b and the side wall of the support plate 4 when swinging.

[0039] One end of the first rope is fixed to the first drum 2, and the other end of the first rope is fixed to the third swing arm 5c. Preferably, the first swing arm 5a is hinged at the end of the first shaft and is provided with a first lifting eye 5a1, and the other end of the second rope is fixed to the first lifting eye 5a1. One end of the second rope is fixed to the second drum 3, and the other end of the second rope is fixed to the first swing arm 5a. Preferably, the third swing arm 5c is hinged at the end of the third shaft and is provided with a third lifting eye 5c1, and the other end of the first rope is fixed to the third lifting eye 5c1.

[0040] In this embodiment, the support plate 1c is provided with a strip-shaped protrusion 1c1 with a semicircular cross section, and the strip-shaped protrusion 1c1 is perpendicular to the plane constructed by the first swing arm 5a, the second swing arm 5b and the third swing arm 5c. Preferably, the strip-shaped protrusion 1c1 is provided with a plurality of strips and arranged in a parallel array. The bottom of the support plate 4 is provided with a strip-shaped groove 4b with a square cross section corresponding to the strip-shaped protrusion 1c1. This structure has a variety of beneficial effects. On the one hand, when the support plate 4 moves to the bottom of the support plate 1c, the strip-shaped protrusion 1c1 can play an anti-slip role; on the other hand, when the support plate 4 is placed on the support plate 1c, the strip-shaped protrusion 1c1 can play a positioning role; in addition, the semicircular strip-shaped protrusion 1c1 cooperates with the square strip-shaped groove 4b to prevent the support plate 4 from sliding relative to the support plate 1c without affecting the rotation of the support plate 4 around the hinge axis.

[0041] In other embodiments, the support plate 1c can also be configured to have a hemispherical protrusion in cross section, with a plurality of hemispherical protrusions provided, and a cubic groove is provided at the bottom of the support plate 4 corresponding to the hemispherical protrusions.

[0042] In order to improve the strength, the present embodiment further provides reinforcing ribs 7 between the vertical plate 1 b and the bottom plate 1 and between the bottom of the supporting plate 1 c and the bottom plate 1 .

[0043] This embodiment also provides a method of use, as follows:

[0044] S1: The pallet 4 is placed on the support plate 1c, and the unmanned aerial vehicle is placed on the frame 4a.

[0045] S2: Figure 1 As shown, the first reel 2 winds the first rope, and the first rope pulls the third swing arm 5c. In order to avoid a dead point or the third swing arm 5c swinging in the opposite direction, the support plate 1c is arranged at a position higher than the hinge between the swing arm and the base plate 1 in this embodiment, so that when the first reel 2 pulls the first rope, the support plate 4 rotates upward.

[0046] The first winding rope pulls the third swing arm 5c until the third swing arm 5c is in line with the straightened first winding rope. During this movement, the second winding drum 3 is in a natural state. The so-called natural state refers to a state that can be pulled at will and is not affected by the driving force.

[0047] S3: Figure 2 As shown, the first reel 2 slowly releases the first winding rope until the first swing arm 5a swings to a vertical downward state and the support plate 4 is located underwater.

[0048] S4: Figure 3 As shown, the first drum 2 winds up the first rope, and the second drum 3 winds up the second rope, so that the first rope and the second rope form a mutually stagnant force to reduce the shaking of the support plate 4.

[0049] S5: The unmanned aerial vehicle starts and detaches from the pallet 4.

[0050] S6: The first reel 2 winds up the first rope until the third swing arm 5c is in line with the first rope. During this movement, the second rope is in a natural state.

[0051] S7: The second reel 3 takes over and winds the second rope until the support plate 4 returns to the supporting plate 1c. During this movement, the first reel 2 is in a natural state.

[0052] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention, rather than to limit the scope of protection of the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the present invention can be modified or replaced by equivalents without departing from the essence and scope of the technical solution of the present invention.
