Background technology
Along with the high speed development of the industries such as diving under water device, ocean petroleum developing, the underwater wireless communication technology more and more comes into one's own.The subsurface communication antenna generally adopted both at home and abroad is at present electrode pair antenna, and namely adopt the electrode pair with certain distance to carry out the pressure difference signal of induction wireless electric wave in water after horizontal polarization, the Signal reception of this antenna restricts by directivity.When antenna direction is parallel to arrival bearing, the receiving gain obtained is maximum, and during the vertical and arrival bearing of antenna direction, then antenna is in collection of letters blind area.
Utility model content
The purpose of this utility model is to provide one that perpendicular antenna can be made to expose sea, Received signal strength direction-free towed buoy formula antenna.
For solving the problems of the technologies described above, the utility model towed buoy formula antenna, comprising: aerial head, is provided with mount pad in one end of described aerial head, described aerial head is provided with spacing hole; Flexible draw bar, described flexible draw bar is " Z " font, and one end of described flexible draw bar is arranged in described aerial head; Antenna, the bottom of described antenna is rotatably connected with described mount pad, and the other end of described flexible draw bar inserts in described antenna, and is connected by pin; Cross, the bottom of cross is inserted in described aerial head, and described cross is provided with shell fragment, and the position of described shell fragment is corresponding with the position of described antenna; Support, one end of described support is inserted in described spacing hole; Elastic mechanism, described elastic mechanism is set in the outside of described support, and described flexible draw bar is connected with described elastic construction; Cable, described cable is connected with described elastic mechanism by transfer block.
Described elastic mechanism comprises: slide block, and described slide block is annular, and described slide block set is located at the outside of described support, and described flexible draw bar is connected with described slide block; Extension spring, described extension spring is set in the outside of described support, and one end of described extension spring is connected with described slide block, is provided with connecting rod at the other end of described extension spring, and described connecting rod is threaded with described transfer block.
Also water tight sheaths is arranged with outside described support and described elastic mechanism.
The quantity of described antenna is four.
The utility model towed buoy formula antenna adopts mechanical automatic folding, and make perpendicular antenna expose sea, Received signal strength is non-directional.Light structure, antenna adopts titanium alloy material, and overall weight is light.

Embodiment
Below in conjunction with accompanying drawing, the utility model towed buoy formula antenna is described in further detail.
As shown in Figure 1 to 4, the bottom of four antennas 8 of the utility model towed buoy formula antenna is rotatably connected with the mount pad 15 of one end of aerial head 1, one end of flexible draw bar 9 is arranged in aerial head 1, the other end of flexible draw bar 9 inserts in antenna 8, connected by pin 10, the bottom of cross 11 is inserted in aerial head 1.
Rounding state: antenna 8 rotates around to mount pad 15, closes up to center, be pressed on the shell fragment 12 of cross 11 bottom antenna 8, make shell fragment 12 store power, and the flexible draw bar 9 on antenna 8 pulls extension spring 4 along with the movement of antenna 8, extension spring 4 is extended, extension spring 4 is in extended state.Now be in non operating state.
Open configuration: after being released by pipeline under water, in water, antenna 8 is subject to the elastic force opened of shell fragment 12, and simultaneously extension spring 4 also applies a pulling force that antenna 8 is opened by flexible draw bar 9 pairs of antennas 8 due to restoring force, finally making antenna 8 in cross state of opening, is now operating state.
Elastic mechanism is mounted on the support 2 in water tight sheaths 5, and support 2 is inserted in the spacing hole 14 of aerial head 1, plays the effect of fixing extension spring 4 direction of motion.Shell fragment 12 provides an initial elastic force by the slide block 3 that is connected with flexible draw bar 9 in antenna 8 closed type, makes antenna 8 be easier to open.
Adopt four antennas 8 to design, make antenna 8 in water by after grabability, cable 7 is in level, now, can ensure to have at least an antenna 8 to expose sea all the time.
Telecommunication cable 7 sheath material is expanded material, and ensure that antenna 8 entirety can float up to the water surface, telecommunication cable 7 adopts vulcanization of rubber mode with the connection of antenna 8.The diameter of antenna 8 is little, four close up after diameter identical with cable 7 diameter.
Transfer block 6 is conversion portions of stube cable 7 and antenna 8, and one end of transfer block 6 is designed with recessed edge, and it bonds coated vulcanized rubber.The other end is screw thread, with the threaded engagement on connecting rod 13, and water tight sheaths 5 to be also screw thread be fixed on support 2, transfer block 6 and water tight sheaths 5 are tightened mutually, can guarantee that screw thread does not loosen.
The utility model towed buoy formula antenna adopts mechanical automatic folding, and make perpendicular antenna expose sea, Received signal strength is non-directional.Light structure, antenna adopts titanium alloy material, and overall weight is light.
Below the preferred embodiment that the utility model is created is illustrated, but the utility model is created and is not limited to described embodiment, those of ordinary skill in the art also can make all equivalent modification or replacement under the prerequisite without prejudice to the invention spirit, and these equivalent modification or replacement are all included in the application's claim limited range.
