Abstract
The utility model relates to an elastic buoy base which is applied to the satellite communication system of micro or small-sized ocean platform and has no horizontal rotation, which mainly comprises a main bracket, an outer circular rotation ring, an inner rod-shaped rotation ring, a cylindrical stainless steel barrel, silicon oil, shock insulation pad and the like. The main bracket is connected with a buoy body, and the shock insulation pad is arranged between the main bracket and the buoy body and is used for preventing the vibration of the buoy body not to be transferred to the main bracket. The outer circular rotation ring is connected with the main bracket through a rotation screw and a rotation hole. The inner rod-shaped rotation ring is connected with the outer circular rotation ring through a rotation ring and a rotation hole. A satellite antenna is fixed at the middle part of the inner rod-shaped rotation ring. A balance weight on the bottom part of the antenna is steeped inside the silicon oil, and the damping of the silicon oil reduces the high-frequent vibration of the antenna. With the satellite antenna base for buoy, the direction of the antenna can be fixed in the shaking ocean environment so as to realize the broadband satellite communication. The satellite antenna base has the advantages of simple structure and low cost; moreover, the antenna can be orientated through the gravity without the electric power servo.
Description
Technical field
The utility model relates to the spring buoy that does not the horizontally rotate satellite antenna base in a kind of satellite communication system that is applied to little, small-sized ocean platform etc., makes that antenna can be directed in the marine environment of swing, thereby realizes wideband satellite communication.
Background technology
Communication in moving antenna (0.6 meter, 0.8 meter, 0.9 meter, 1.2 meters) is the communication in moving antenna at the exploitation of broadband mobile satellite communication, this antenna at carriers such as car, ship, aircrafts at the volley, all the time the employed synchronous satellite of high precision alignment guarantees high accuracy, broadband satellite communication.
Used " communication in moving " antenna is the product of comparatively ripe and extensive use on land Emergency communication vehicle and the marine vessel.But the directed servo system structure complexity that it adopts, price is high, is difficult to use among the abominable marine environment of unattended duty for a long time.Because buoy has relative position and fixes, its level or the vertical tens of meters Syncom satellite of displacement outside tens thousand of kilometers, the variation of antenna elevation angle degree is very little, can be used as constant.
Therefore adopt present technique then can effectively solve the directed problem of antenna on the spring buoy.
The utility model content
The technical problems to be solved in the utility model provides a kind of buoy satellite antenna base, makes that antenna can be directed in the marine environment of swing, thereby realizes wideband satellite communication.
For solving the problems of the technologies described above, the utility model adopts following technical scheme: a kind of buoy satellite antenna base, this buoy with the satellite antenna base comprise base, be installed on outer change on the base, be fixed in interior change in the outer change, the antenna connecting rod is vertically passed in change in this; The oil drum that silicone oil is housed is installed on the described base, and the lower end of antenna connecting rod is provided with the damping sheet counterweight and stretches in the oil drum that silicone oil is housed.
As one of optimal way of the present utility model, described antenna connecting rod upper end is provided with the antenna connecting plate of fixed antenna.
As one of optimal way of the present utility model, this buoy is provided with vibration isolator with satellite antenna base bottom.
As one of optimal way of the present utility model, described outer change is connected by bolt with base.
The utility model is mainly used in the spring buoy that does not horizontally rotate, and in the satellite communication system of little, small-sized ocean platform etc., makes that antenna can be directed in the marine environment of swing, thereby realizes wideband satellite communication.Superiority of the present utility model is: 1. structure is extremely simple, and cost is low; 2. do not need electric power servo, only just can make antenna direction by gravity.

Embodiment
Please refer to Fig. 1 to shown in Figure 3, the utility model is at buoy, have wide practical use in the engineerings such as little, small-sized ocean platform, it relates to the spring buoy that does not the horizontally rotate satellite antenna base in a kind of satellite communication system that is applied to little, small-sized ocean platform etc., and this buoy mainly comprises base 7, outer change 5, interior change 6, cylindrical stainless oil drum 10, silicone oil 9, shock insulation pad 14 etc. with the satellite antenna base.
Described base 7 is connected with buoy float, and the centre installs vibration isolator 12 additional, in order to isolate the transmission of buoy float vibrations to base 7.Outer change 5 links to each other with rotating hole by rotary screw with base 7.Interior change 6 links to each other with rotating hole by rotary screw with outer change 5.
Change middle part in satellite antenna connecting rod 3 is vertically fixed on.The damping sheet counterweight 8 of antenna connecting rod 3 lower ends is immersed in the silicone oil 9, and the latter's damping reduces the dither of antenna.
The utility model is mainly used in the spring buoy that does not horizontally rotate, and in the satellite communication system of little, small-sized ocean platform etc., makes that antenna can be directed in the marine environment of swing, thereby realizes wideband satellite communication.
Superiority of the present utility model is: structure is extremely simple, and cost is low; Do not need electric power servo, only just can make antenna direction by gravity.
Above-mentioned description to embodiment is can understand and use the utility model for ease of those skilled in the art.The person skilled in the art obviously can easily make various modifications to these embodiment, and needn't pass through performing creative labour being applied in the General Principle of this explanation among other embodiment.Therefore, the utility model is not limited to the embodiment here, and those skilled in the art should be within protection range of the present utility model for improvement and modification that the utility model is made according to announcement of the present utility model.
