[0033] In order to make the purpose, technical solution and advantages of the present application clearer, the technical solution of the present application will be clearly and completely described below in combination with the specific embodiments of the present application and the corresponding drawings. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present application.

[0034] like Figure 1-6 As shown, a quiver cover for heat preservation and protection of a rocket is a flexible structure and is covered on the outside of the rocket to provide heat preservation and protection for the rocket.

[0035] Specifically, the arrow jacket comprises an end cap 11 and an arrow jacket body 12, wherein the end cap 11 is fixedly arranged on the upper part of the arrow jacket body 12 and is fixedly connected to the arrow jacket body 12. The inner size of the arrow jacket is larger than the outer size of the rocket, so that there is a space for gas to pass between the inner surface of the arrow jacket and the outer surface of the rocket. The bottom of the end cap 11 is detachably fixedly connected to the arrow jacket body 12.

[0036] As an embodiment of the present invention, the jacket body 12 includes a plurality of jacket body pieces, and adjacent jacket body pieces are detachably fixedly connected in the length direction thereof. The connection between adjacent jacket body pieces is an opening and closing seam 13 .

[0037] In the present embodiment, the quiver body 12 comprises a first quiver body piece 210, a second quiver body piece 220, a third quiver body piece 230 and a fourth quiver body piece 240. The side edges of the first quiver body piece 210, the second quiver body piece 220, the third quiver body piece 230 and the fourth quiver body piece 240 are all provided with Velcro 124 for fixing the quiver body pieces. By virtue of the adhesive action of the Velcro 124, the first quiver body piece 210, the second quiver body piece 220, the third quiver body piece 230 and the fourth quiver body piece 240 can be assembled into the quiver body 12. Meanwhile, when the quiver body 12 is disassembled, the quiver body 12 can be disassembled at the opening and closing seam 13 by tearing any one of the first quiver body piece 210, the second quiver body piece 220, the third quiver body piece 230 and the fourth quiver body piece 240, thereby realizing the rapid disassembly and assembly of the quiver. At the same time, by relying on the Velcro 124 bonding method, the production cost of the flexible quiver can be effectively reduced.

[0038] Specifically, Velcro fleece and Velcro hook surfaces are respectively fixed on different surfaces of the edges of both sides of the body piece of the quilt. For example, at the connection between the first quilt body piece 210 and the second quilt body piece 220, the Velcro fleece surface is fixed on the edge of the outer surface of the first quilt body piece 210, and the Velcro hook surface is fixed on the inner surface of the second quilt body piece 220. The Velcro fleece surface and the Velcro hook surface are bonded to achieve a detachable fixed connection between the two.

[0039] In addition, without limiting the efficiency of assembly and disassembly, other connection methods that can achieve detachable and fixed quiver body panels can also be applied to the present invention and solve corresponding technical problems. For example, adjacent quiver body panels can be fixed by means of knots or zippers.

[0040] Further, the quiver body 12 also includes a plurality of pulling ropes 123 fixedly connected to the quiver body pieces; each quiver body piece is fixed with at least one pulling rope 123. By pulling the pulling ropes 123, the quiver body 12 can be disassembled without the aid of other lifting equipment.

[0041] Furthermore, the arrow guard also includes an opening and closing seam cover cloth 14 covering the outer surface of the opening and closing seam 13 of the arrow guard body 12. The opening and closing seam cover cloth 14 is made of waterproof material, and the setting of the opening and closing seam cover cloth 14 can further prevent external rain and snow from entering the inside of the arrow guard. In addition, in the rocket sea launch environment, the setting of the opening and closing seam cover cloth 14 can also effectively prevent seawater rolled up by wind and waves from entering the inside of the arrow guard, and effectively prevent the arrow body from being corroded by seawater.

[0042] In addition, in some other embodiments of the present invention, the arrow cover body 12 may also adopt a non-detachable integral structure. When the rocket needs to be thermally insulated and protected, it is inserted from the upper end of the rocket, and after the thermal insulation and protection are completed, it is completely removed from the upper part of the rocket.

[0043] As another embodiment of the present invention, the end cap 11 includes an arc-shaped body 111 and a plurality of end cap pieces 12 ; adjacent end cap pieces 112 are fixedly connected to each other; and a plurality of end cap pieces 112 are fixedly connected to the edge of the arc-shaped body 111 .

[0044] Preferably, the bottom of the end cap 11 and the upper part of the arrow body 12 are detachably fixedly connected by Velcro 124 .

[0045] In addition, the bottom of the end cap 11 and the upper part of the arrow body 12 can also be fixedly connected by gluing, sewing, pressing glue, etc.

[0046] As another embodiment of the present invention, the arrow body 12 includes a first cone section 121 and a column section 122 which are fixedly connected in sequence; the upper end of the first cone section 121 is fixedly connected to the end cap 11; the lower end of the first cone section 121 is fixedly connected to the column section 122, and the first cone section 121 and the column section 122 are both vertically provided with an opening and closing seam 13.

[0047] As another embodiment of the present invention, the arrow cover further includes a flexible support block 15; the flexible support block 15 is arranged in the cavity of the arrow cover body 12. By setting the flexible support block 15, a certain gap can be provided between the arrow cover and the arrow body, ensuring that there is a gap for air flow in the arrow cover, and ensuring that the arrow body at this position is in a corresponding temperature and humidity state. At the same time, the setting of the flexible support block 15 can also reduce the friction between the arrow cover and the surface of the arrow body, and reduce the potential damage caused by the arrow cover rubbing against the surface of the arrow body multiple times under harsh environmental conditions.

[0048] Preferably, the flexible support block 15 is made of sponge, rubber, silicone or is surrounded by a fabric bag filled with foaming material.

[0049] Preferably, the arrow guard is made of antistatic coated cloth.

[0050] As another embodiment of the present invention, the interior of the arrow cover is filled with heat-insulating material.

[0051] As another embodiment of the present invention, the arrow cover is made of a double-layer fabric with good air tightness. There is an air cavity between the double-layer fabric, and the air cavity is filled with gas. Relying on the effect of the air cavity, the rocket can be kept warm and protected.

[0052] like Figure 6As shown, when in use, the arrow cover 10 can be assembled and sleeved on the outside of the rocket, so as to protect the rocket in severe weather such as strong winds and rain and snow, and ensure the safety of the arrow body. Before the rocket is launched, the arrow cover 10 is disassembled or removed as a whole to be separated from the rocket.

[0053] Furthermore, when in use, the air conditioner 20 is connected to the inside of the arrow cover 10 through a pipeline, and the temperature and humidity inside the arrow cover 10 are further adjusted by the setting of the air conditioner 20, thereby effectively ensuring the temperature and humidity inside the arrow cover, and providing a suitable temperature and humidity environment for the rocket engine and related components.

[0054] As another embodiment of the present invention, Figure 7-8 As shown, the arrow body 12 also includes a second cone section 125; the upper end of the second cone section 125 is fixedly connected to the lower end of the column section 122, and the first cone section 121, the column section 122 and the second cone section 125 are all provided with an opening and closing seam 13.
