The antenna assembly 2 includes an antenna mast 21 and a plurality of springs 22, the antenna mast 21 includes a plurality of antenna tubes 211 coaxially arranged, the plurality of antenna tubes 211 are sequentially inserted and assembled to expand or contract the antenna mast 21, thereby adjusting the length of the antenna mast 21, the antenna tubes 211 at the bottom of the antenna mast 21 are fixed in the buoy barrel 11, and each spring 22 is arranged on the corresponding antenna tube 211 to automatically drive the antenna mast 21 to extend out of the buoy barrel 11 after being expanded.
The control assembly includes a controller and a signal generator (not shown), the controller being electrically connected to the driver 14 and the signal generator, respectively, the signal generator being electrically connected to the at least one antenna tube 211.
For the short-wave buoy antenna provided by the embodiment of the invention, when the short-wave buoy antenna is not in use, the sealing plate 12 is matched with the second locking piece 15 through the first locking piece 13, so that the sealing of the sealing plate 12 to the buoy barrel 11 is realized, at the moment, the sealing plate 12 overcomes the elasticity of the plurality of springs 22 to retract the antenna rod 21 in the buoy barrel 11 (see fig. 2), and the short-wave buoy antenna is in a storage state, so that the whole length of the short-wave buoy antenna is smaller.
And when the communication requirement is needed, the short wave buoy antenna is put into the water. After a period of time, the short wave buoy antenna floats out of the sea under the buoyancy action of the buoy barrel 11, the controller transmits a control signal to the driving part 14, and the driving part 14 drives the second locking part 15 to move, so that the first locking part 13 and the second locking part 15 are separated, and the sealing effect of the sealing plate 12 on the opening of the buoy barrel 11 can be relieved. At this time, the plurality of antenna tubes 211 are gradually unfolded by the elastic force by the spring 22, and the entire antenna rod 21 is unfolded and extended out of the float 11 (the sealing plate 12 is pushed open by the antenna rod 21). And, the controller transmits the control signal to the signal generator, which generates a corresponding signal and transmits it to the antenna tube 211, thereby transmitting the communication information.
That is, the short wave buoy antenna provided by the embodiment of the invention not only can be in a collection state when not in use, but also can be rapidly unfolded before use so as to meet the communication requirement.
The model of the controller may be ARMCortex-M4, for example.
In one implementation of the present invention, fig. 4 is a cross-sectional view of a second short wave buoy antenna provided in an embodiment of the present invention, as shown in fig. 4, one end of each spring 22 is sleeved or inserted on the top end of a corresponding antenna tube 211, and the other end of each spring 22 is sleeved or inserted on the top end of an adjacent antenna tube 211.
In the above embodiment, when the restriction of the sealing plate 12 is released, each compressed spring 22 stretches the adjacent two antenna tubes 211 by the elastic force, and the whole antenna rod 21 is unfolded.
Illustratively, the outer wall of the top end of each antenna tube 211 is provided with a baffle ring 24, and two ends of each spring 22 are clamped between two adjacent baffle rings 24, so that the two ends of each spring 22 are positioned.
In another implementation manner of the present invention, fig. 5 is a cross-sectional view of a third short wave buoy antenna provided in an embodiment of the present invention, as shown in fig. 5, a sleeve 23 is coaxially and fixedly sleeved on the top of the other antenna tubes 211 (the middle and top antenna tubes 211) except for the bottom antenna tube 211, the bottom ends of the sleeve 23 are spaced from the corresponding antenna tubes 211, one end of each spring 22 is sleeved on the corresponding antenna tube 211 or the bottom end of the sleeve 23, and the other end of each spring 22 is inserted in the top end of the adjacent sleeve 23.
In the above embodiment, when the antenna rod 21 is not extended, the positioning of the springs 22 is achieved by the sleeve 23, so that the compression amount of each spring 22 can be reduced, and the compression ratio of each spring 22 can be prevented from becoming excessively large. In addition, the sleeve 23 can axially isolate two adjacent springs 22, so that the two adjacent springs 22 are prevented from interfering with each other in the expansion and contraction process.
It will be readily appreciated that the compression ratio of the spring 22 should not be more than 50% in normal use. When the compression ratio is excessively large, the spring 22 is hardly restored to the free length, and thus more springs 22 and antenna tubes 211 need to be provided, resulting in an increase in cost. In addition, for the short wave buoy antenna shown in fig. 5, the compressed length of each spring 22 is close to the length of a single antenna tube 211 (see fig. 2), and when the length of each spring 22 is extended to the length of two antenna tubes 211 after the extension of the antenna rod 21, the compression ratio is just 50%, so that the maximum expansion performance of the springs 22 can be ensured, and the number of the springs 22 and the antenna tubes 211 can be reduced when the same extension length is reached, thereby reducing the cost.
Further, the antenna tube 211 at the bottom and the outer wall of the bottom end of each sleeve 23 are respectively provided with a baffle ring 24 coaxially arranged, and two ends of each spring 22 respectively abut against the corresponding baffle ring 24 and the top end of the corresponding sleeve 23, so that the two ends of the spring 22 are conveniently positioned through the baffle rings 24.
In yet another implementation of the present invention, see fig. 6-8, one end of the top spring 22 (third spring 223) is inserted over the top antenna tube 211 (fourth antenna tube 2114) and the other end of the top spring 22 is inserted over the adjacent antenna tube 211 (third antenna tube 2113).
For the plurality of antenna tubes 211 in the middle, the top of each antenna tube 211 is coaxially and fixedly sleeved with a sleeve 23, the bottom ends of the sleeve 23 and the corresponding antenna tube 211 are arranged at intervals, one end of each other spring 22 (the second spring 222 and the first spring 221) is sleeved on the corresponding antenna tube 211 or the bottom end of the sleeve 23, and the other end of each other spring 22 is inserted into the top end of the adjacent sleeve 23.
In the above embodiment, by providing the top spring 22 (third spring 223) in the antenna tube 211 (third antenna tube 2113 and fourth antenna tube 2114), it is possible to avoid the arrangement of the sleeve 23 on the top antenna tube 211, thereby reducing the outer diameter and mass of the top antenna tube 211, facilitating deployment.
Illustratively, the top of the fourth antenna tube 2114 is plugged with a cap 214, the bottom of the third antenna tube 2113 is plugged with a cap 214 as well, and the top third spring 223 is sandwiched between the two caps 214.
For a better understanding of the action of the springs 22, the operation of the springs 22 will now be described in detail:
fig. 6 is a schematic diagram showing a first state of the first short wave buoy antenna according to the embodiment of the invention, as shown in fig. 6, when the second spring 222 pushes up the second antenna tube 2112.
Fig. 7 is a schematic diagram showing a second state of the first short wave buoy antenna according to the embodiment of the present invention, as shown in fig. 7, where the first spring 221 pushes up the third antenna tube 2113.
Fig. 8 is a schematic diagram illustrating a third state of the first short wave buoy antenna according to the embodiment of the present invention, as shown in fig. 8, where the third spring 223 pushes up the fourth antenna tube 2114. The bottom of the first antenna tube 2111 has a base 215, and the base 215 is fixedly mounted within the float bucket 11.
During the actual deployment of the antenna mast 21, the first spring 221, the second spring 222, and the third spring 223 start to extend simultaneously, regardless of the order.
It will be readily appreciated that since the top third spring 223 is disposed within the antenna tube 211, there is no need to provide a stop ring on the sleeve 23 on the outer wall of the third antenna tube 2113, in which case the length of this sleeve 23 may be reduced.
Illustratively, the diameters of the first antenna tube 2111, the second antenna tube 2112, the third antenna tube 2113, and the fourth antenna tube 2114 may be, in order, different gauge aluminum alloy AL6063-T6 tubing of 30mm, 26mm, 22mm, and 18 mm. In addition, the length of the 4-section antenna tube 211 after being fully unfolded is greater than 5.7m.
Illustratively, each sleeve 23 is an insulating structure, thereby insulating each antenna tube 211.
It should be noted that the number of the antenna tubes 211 may be 2, 3 or 4, which is not limited by the present invention.
To avoid detachment between the adjacent two antenna tubes 211 during deployment, the inner wall of one antenna tube 211 is externally flanged 212, and the outer wall of the adjacent other antenna tube 211 is provided with an inner flange 213 to limit the outer flange 212 (see fig. 6).
In one implementation of the invention, the driving member 14 is a rotating electric machine, the first locking member 13 and the second locking member 15 are hooks, and the rotating electric machine is configured such that when the rotating electric machine drives the second locking member 15 to rotate, the first locking member 13 and the second locking member 15 are separated.
In the above embodiment, the control signal is transmitted to the rotating electric machine by the controller, and the rotating electric machine drives the second locking member 15 to rotate, so that the first locking member 13 and the second locking member 15 are separated. Thereafter, the sealing plate 12 is pushed open during the deployment of the antenna mast 21 by the elastic force of the plurality of springs 22.
In another implementation of the present invention, the driving member 14 is a linear motor, the first locking member 13 is a locking ring, and the latch of the second locking member 15 is configured such that the first locking member 13 and the second locking member 15 are separated when the linear motor drives the second locking member 15 to perform linear motion.
In the above embodiment, the control signal is transmitted to the linear motor by the controller, and the linear motor drives the second locking member 15 to linearly move, so that the first locking member 13 and the second locking member 15 are separated. Thereafter, the sealing plate 12 is pushed open during the deployment of the antenna mast 21 by the elastic force of the plurality of springs 22.
Illustratively, the float bowl 11 is an aluminum structural member.
Specifically, the buoy barrel 11 is made of AL6061-T5 material, the outer diameter of the buoy barrel 11 can be 180mm, the thickness of the buoy barrel 11 can be 15mm, the height of the buoy barrel 11 can be 1700mm, and the material has the characteristics of certain corrosion resistance, high strength, light weight, weldability, good processability and the like.
When not in use, the antenna mast 21 is retracted within the float barrel 11, the retracted size of the antenna mast 21 being less than 1.7m. When in use, the antenna rod 21 stretches out from the buoy barrel 11, thereby meeting the requirement that the effective length of the antenna rod 21 outside the buoy barrel 11 is more than 4 m.
It will be readily appreciated by those skilled in the art that the foregoing description is merely a preferred embodiment of the invention and is not intended to limit the invention, but any modifications, equivalents, improvements or alternatives falling within the spirit and principles of the invention are intended to be included within the scope of the invention.
