Specific embodiment
As shown in Figure 1, being portable composite material shortwave whip antenna working condition form of the invention, i.e., base of the invention
This form, it is by root end cap 1, inside bistable state composite material tube 2, outside bistable state composite material tube 3, copper wire 4, locking strap
5, top end cover 6, fixed rope 7, fixing glue 8 are constituted.
Inside bistable state composite material tube 2 and outside bistable state composite material tube 3 are multiple using 2 layers of plain weave glass fibre
Condensation material prepreg cloth curing molding, using vacuum-bag process technique, prepreg cloth is pressed from both sides through broadwise and the axial of molding die when laying
Angle is 45 °, inside bistable state composite material tube 2,3 extended state section subtended angle of outside bistable state composite material tube after curing molding
It is 300 °, with a thickness of 0.6mm.
The principle of inside bistable state composite material tube 2 and outside bistable state composite material tube 3 are as follows: meet specific curvature rigidity
The composite material opening column package of distribution and geometric dimension has two stable states, is that stretching, extension stable state and curling are steady respectively
Determine state, the corresponding two strain energy Local Minimum states of the two stable states.Extended state is in working condition, and has carrying energy
Power, rolled state are travel position, and curling is close, do not need extraneous load constraint.
4 diameter 0.1mm of copper wire or so, in inside, bistable state composite material tube 2 is laid with when composite material is laid with and is embedded in advance,
Deformation is consistent with inside bistable state composite material tube 2.On the prefabricated limited block to root end cap 1 of feeding interface 1-1.
When working condition, inside bistable state composite material tube 2 and outside bistable state composite material tube 3 are open and are inserted into relatively,
So that the both ends of inside bistable state composite material tube 2 and outside bistable state composite material tube 3 are aligned, 4 one end of copper wire and root end
Distinguish at the both ends of feeding interface 1-1 connection on lid 1, inside bistable state composite material tube 2 and outside bistable state composite material tube 3
It is connect with root end cap 1 and top end cover 6, and the locking of locking strap 5 is respectively adopted, root end cap 1 is fixed to by three fixing glues 8
Ground, one end of three fixed ropes 7 connect with the connecting hole system of top end cover 6 respectively, the other end difference of three fixed ropes 7
With 8 system of the other three fixing glue connect, be fixed determine rope 7 three fixing glues 8 centered on root end cap 1, be uniformly distributed consolidate
It is scheduled on radius circle appropriate.
When transport storage, the fixed rope 7 of three to be connected with fixing glue 8 is unlocked, fixing glue 8 is taken out, by inside bistable state
Composite material tube 2 and outside bistable state composite material tube 3 are horizontally arranged to ground, unlock three connected with 6 system of top end cover admittedly
Determine rope 7, opens the locking strap 5 of root end cap 1 and top end cover 6, taken respectively from the both ends of inside bistable state composite material tube 2
Root end cap 1 and top end cover 6 out extract inside bistable state composite material tube 2 out from outside bistable state composite material tube 3,
Inside bistable state composite material tube 2 and outside bistable state composite material tube 3 are crimped to curling stable state respectively, is completed portable
The storage of composite material shortwave whip antenna device.
As shown in Fig. 2,3,5, inside bistable state composite material tube 2 and the opening of outside bistable state composite material tube 3 are inserted relatively
Enter, both ends are concordant, connect with root end cap 1, wherein inside bistable state composite material tube 2 and outside bistable state composite material tube 3
The prefabricated limit hole 2-5 in root, matched with the limited block 1-1 of root end cap 1, inside bistable state composite material tube 2 and outside are double
The inside of metastable composite pipe 3 matches connection with the cylindrical surface 1-4 of root end cap 1 and cylindrical surface 1-5, improves inside bistable state
The axial direction of composite material tube 2 and outside bistable state composite material tube 3, bending and distortion bearing capacity.The limited block of root end cap 1
The upper prefabricated feeding interface 1-2 of 1-1.It is evenly arranged three fixation hole 1-3 on the end face 1-7 of root end cap 1, is used for and fixing glue 8
Connection.
As shown in Figure 2,4, locking strap is made of fastener 5-1, fastener pin 5-2, fastener 5-3, holding screw 5-4, inside
After bistable state composite material tube 2 and outside bistable state composite material tube 4 are connect with root end cap 1, by the fastener 5-1 of locking strap 5
