Referring to fig. 1, fig. 1 is a schematic structural diagram of a tossing type unmanned aerial vehicle protection cylinder provided in an embodiment of the present application.
The application provides a type of jettisoning unmanned vehicles protection section of thick bamboo includes: a protective cylinder body 1 and a heating layer (not shown in the figure) covering the inner surface of the protective cylinder body 1; the structure of the protective cylinder body 1 is a sandwich structure of glass fiber reinforced plastics and an insulating layer (such as a polyurethane foam layer); the heating layer can be heating wires, electrothermal films and other parts capable of generating heat, and the heating layer is preferably an electrothermal film in the application.
3 referring 3 to 3 fig. 3 2 3, 3 fig. 3 2 3 is 3 a 3 cross 3- 3 sectional 3 view 3 taken 3 along 3 line 3 a 3- 3 a 3 of 3 fig. 3 1 3. 3 Specifically, the protective cylinder body 1 sequentially comprises a glass fiber reinforced plastic inner wall 101, an insulating layer 102 and a glass fiber reinforced plastic outer wall 103 from inside to outside, that is, the glass fiber reinforced plastic inner wall 101 and the glass fiber reinforced plastic outer wall 103 clamp the insulating layer 102 together, and the glass fiber reinforced plastic inner wall 101, the insulating layer 102 and the glass fiber reinforced plastic outer wall 103 are integrally formed to form an integral protective cylinder body 1 without a connecting seam. In order to ensure the heat preservation effect, the thickness ratio of the glass fiber reinforced plastic inner wall 101, the heat preservation layer 102 and the glass fiber reinforced plastic outer wall 103 is preferably 1:3:1, and other thickness ratios can be adopted according to the actual heat preservation requirement, specifically, the thicknesses of the glass fiber reinforced plastic inner wall 101, the heat preservation layer 102 and the glass fiber reinforced plastic outer wall 103 are respectively 2mm, 6mm and 2 mm.
Specifically, the heating layer is preferably a PI electric heating film layer in the application, and the PI electric heating film is also called a high-heat electric heating film, is a transparent metal flexible electric heating film, and is thin in thickness and small in occupied volume. After the protective cylinder is adhered to the inner surface of the protective cylinder body 1, the thickness of the protective cylinder is thin, and the occupied volume is small, so that the internal space of the protective cylinder body 1 can be saved, and the occupied space of sensitive components of a submachine is increased; the PI electric heating film has high integration degree, so that the speed of pasting the PI electric heating film on the inner surface of the protective cylinder body 1 is high, and the operation of pasting the heating layer is convenient and simple; in addition, because the insulating layer of PI electric heat membrane is the polyimide film, it has good dielectric strength, excellent dielectric strength, higher heat-conduction efficiency to the heat-generating body of PI electric heat membrane has superstrong stability, consequently the type of jettisoninging unmanned vehicles protection section of thick bamboo of this application can provide good heating performance.
On the basis, the glass fiber reinforced plastic inner wall 101 and the glass fiber reinforced plastic outer wall 103 of the protection cylinder body 1 are both the inner wall and the outer wall of the protection cylinder body 1 formed by paving, thermally curing and laminating multiple layers of glass fiber reinforced plastic prepreg.
specifically, a glass fiber reinforced plastic prepreg is formed by reinforcing a resin matrix such as an unsaturated polyester, an epoxy resin, or a phenol resin matrix with glass fibers. Cutting the glass fiber reinforced plastic prepreg into a preset shape, and paving the cut glass fiber reinforced plastic prepreg on a protective cylinder mould, wherein the prefabricated protective cylinder body 1 is in a long and thin cylindrical shape, and the protective cylinder mould is also in a long and thin cylindrical shape. Pre-compaction is needed after the first layer of glass fiber reinforced plastic prepreg is paved, 3-4 layers of glass fiber reinforced plastic prepreg can be paved in the subsequent process, and then the glass fiber reinforced plastic inner wall 101 is formed by pre-compacting the plurality of layers of glass fiber reinforced plastic prepreg.
Then, the outer surface of the glass fiber reinforced plastic inner wall 101 is covered with an insulating layer 102, specifically, a polyurethane foam layer, or other insulating materials may be used. Wherein, polyurethane foam's thermal conductivity is lower, can guarantee higher thermal insulation performance to because polyurethane foam layer can be at the circumference of glass steel inner wall 101 complete cover surface, do not have the heat leak channel, higher thermal insulation performance of assurance that can be further.
After the outer surface of the glass fiber reinforced plastic inner wall 101 is covered with the insulating layer 102, glass fiber reinforced plastic prepreg is continuously paved and pre-compacted on the outer surface of the insulating layer 102, and the glass fiber reinforced plastic outer wall 103 is formed by pre-compacting multiple layers of glass fiber reinforced plastic prepreg. After the glass fiber reinforced plastic outer wall 103 is formed, the protection cylinder body 1 is packaged by a vacuum bag and is sent into an oven to be integrally cured and formed.
Preferably, referring to fig. 3, the insulating layer 102 is completely covered between the inner glass fiber reinforced plastic wall 101 and the outer glass fiber reinforced plastic wall 103, and the insulating layer 102 is chamfered at the opening of the protective cylinder body 1, so that the inner glass fiber reinforced plastic wall 101 and the outer glass fiber reinforced plastic wall 103 are directly bonded at the opening of the protective cylinder body 1 to form a complete sandwich structure of the insulating layer. Because the glass fiber reinforced plastic inner wall 101 and the glass fiber reinforced plastic outer wall 103 are directly bonded at the opening of the protection cylinder body 1, the edge folding effect is achieved at the opening of the protection cylinder body 1, and the strength of the opening of the protection cylinder body 1 is ensured.
On the basis, in order to ensure the flatness of the outer surface of the protection cylinder body 1, that is, the flatness of the outer surface of the outer glass fiber reinforced plastic wall 103, a pressure equalizing plate can be placed on the outer surface of the outer glass fiber reinforced plastic wall 103 when the protection cylinder body 1 is manufactured. The pressure equalizing plate is a metal plate with a smooth surface, is manufactured according to the outer surface of the protective cylinder, and is arranged on the outer surface of the glass fiber reinforced plastic prepreg paving layer before packaging and curing so as to ensure that the temperature and the pressure are uniformly transmitted in the curing process and the outer surface of the cured protective cylinder body 1 is smooth.
Because the inner wall and the outer wall of the protection cylinder body 1 are both made of glass fiber reinforced plastics, the thermal conductivity of the protection cylinder body is lower, and the thermal insulation performance of the protection cylinder is further ensured. And the protection section of thick bamboo body 1 of this application is through spreading the mode integrated into one piece of subsides, thermosetting, consequently the operation such as a preparation protection section of thick bamboo body 1 need not welding, riveting, has consequently just avoided the shortcoming that the preparation work load is big, the work degree of difficulty is high.
In addition, still because protection section of thick bamboo body 1 is spread on the protection section of thick bamboo mould and is pasted, thermosetting and the shaping, consequently fashioned internal surface of protection section of thick bamboo body 1 is comparatively smooth, and surface quality is higher, easily pastes PI electric heat membrane to functional subassembly such as guide rail draw-in groove is still easily installed.

If the guide rail 2 has a guide groove, the rail engaged with the guide groove and connected to the slave machine is a protrusion, and if the guide rail 2 has a guide protrusion, the rail engaged with the guide protrusion and connected to the slave machine is a groove. When the submachine flies, the rail of the submachine slides to the cylinder opening of the protection cylinder body 1 relative to the guide rail 2, so that the submachine flies.
Since the sub-machine is generally separated from the protection cylinder in advance when the sub-machine is separated from the protection cylinder, referring to fig. 1, when the inner diameter of the section of the cylinder body 11 of the protection cylinder body 1 facing the cylinder opening is larger than the inner diameter of the section of the cylinder body 12 of the protection cylinder body 1 facing the cylinder bottom (for example, the inner diameter of the cylinder body 11 is larger than the inner diameter of the cylinder body 12 by the thickness of the heat insulation layer 2), the guide rail 2 extends from the direction of the cylinder bottom of the protection cylinder body 1 to the position where the inner diameter of the cylinder opening of the protection cylinder body 1 is larger, so as to reduce the risk of the guide rail sliding and.
In addition, in order to fixedly connect the protection cylinder with the sub-machine, that is, to fix the protection cylinder body 1 with the sub-machine, please continue to refer to fig. 3, the edge of the cylinder opening of the protection cylinder body 1 may be connected with the flange 3, and the protection cylinder body 1 is connected to the sub-machine through the flange 3, so as to realize the butt joint of the protection cylinder and the sub-machine. Specifically, a through hole is provided at a position where the inner diameter of the cylinder opening of the protective cylinder body is increased, that is, at a position where the outer surface of the inner glass fiber reinforced plastic wall 101 and the inner surface of the outer glass fiber reinforced plastic wall 103 are bonded to each other, so that a bolt is inserted through the through hole and the through hole of the flange to fixedly connect the protective cylinder body 1 and the flange 3. In addition, a lifting lug is fixed on the outer surface of the protection cylinder body 1, so that the protection cylinder is fixed with the main machine through the lifting lug.
