Description
Technical field
The present invention relates to a kind of laying method and underwater base station box of radio base station feed line, being a kind of method that part is installed of using on the base station box of the communication base station of automatic operation in a kind of cellular radio communication system, is the radio-frequency (RF) base station case with diving function that a kind of less radio-frequency base station box is introduced method and this method of use of radio frequency ultra-soft feed line.
Background technology
Cellular radio communication system has become generally acknowledged the most practical ground wirelessmobile communication system in mobile communcations system.The shortcoming of this communication system is to arrange a plurality of automatic communication base stations in the communication distance on ground, so that communication signal covers whole communications zone.The way in past is on the building top in city automatic communication base station to be installed directly.Though this method installation method is simple and practical, has destroyed the attractive in appearance of city, and the building of communications zone is less or when not having building, then this method is just unworkable.Direct mounted base station on the ground certainly, but attractive in appearance and safety problem just will be very outstanding.The best way is exactly that the base station is located in the vertical shaft of underground communication line.But it is more that communication base station is located at the problem of bringing in the vertical shaft.At first, the problem of waterproof is extremely important, because the communication base station of installing on the face of land or building has only rainproof problem, situation about being immersed in water is arranged seldom as a rule, even soak also just in very shallow water.Situation in vertical shaft has then been made a world of difference, and vertical shaft is often filled up by rainwater, if adding the depth of water on road surface, the depth of water of 0.5-1 rice will be arranged at least in the vertical shaft.That is to say that the base station that is placed in the vertical shaft will stand the pressure of the depth of water of 0.5-1 rice at least.The space that more sharp-pointed is in the vertical shaft is narrow and small, and the connection cable of base station and exterior antenna is a kind of radio frequency cable of special use, and this is a kind of special cables of being made up of inside and outside two-layer copper pipe and middle filler.The degree of difficulty of bending that can the phenomenon copper pipe, though this special cable has taken into full account the flexibility of cable in design, can be crooked within the specific limits.But also must be greater than 12 centimetres with regard to its radius of curvature of degree of crook that present technology is best, the again little outer tube of cable that will make of radius of curvature produces distortion, light then cause the inside induction reactance of cable to change to influence communication quality, heavy then make cable gross distortion fracture communicating interrupt.Because the specific (special) requirements of this cable has caused certain difficulty to the maintenance and the maintenance of communication base station in the vertical shaft.Must find a kind of new method to solve the contradiction of waterproof and maintenance.
Summary of the invention
For overcoming prior art problems, the present invention proposes a kind of winding method and diving radio-frequency (RF) base station case of radio frequency feed line, designed a kind of cylindrical shape base station box of pressure under water of standing most, the top cover of cylindrical shape base station box can be opened, and is used for maintenance and maintenance to inside equipment.For making box equipment be convenient to safeguard that the equipment in the case is together mentioned with case lid, for can together being mentioned with case lid, the radio frequency cable adopted special method to arrange cable, and make cable neither influence mentioning also can not kill and losing bad cable of case lid.
The object of the present invention is achieved like this: a kind of laying method of radio base station feed line, the base station box of described radio-frequency (RF) base station is that cylindrical shape is placed on the silo bottom support, feeder line is connected box equipment with the case outside antenna, the step of the laying method of described feeder line is:
The feeder line that extends straight down is fixed on the metope of vertical shaft;
The radius of curvature that allows with feeder line when feeder line is near cylindrical shape base station box bottom is with 80～100 ° angular bend feeder line;
With at this moment near the feeder line of horizontal attitude along cylindrical shape base station box excircle spiral upthrow around;
When the feeder line of coiled coil during near the upper edge of cylindrical shape base station box, the radius of curvature that feeder line is allowed with feeder line straight up is with 80～100 ° angular bend feeder line;
With the radius of curvature that at this moment allows with feeder line, with 170～190 ° angular bend feeder line near straight up feeder line;
At this moment straight down feeder line is penetrated case lid by the water-proof cable through wires hole.
A kind of diving radio-frequency (RF) base station case that uses said method, comprise support, be fixed on the cylindrical box that the bottom face on the support is shut fully, there is a round platform greater than drum diameter the upper edge of casing, be stamped the case lid identical on the round platform with the round platform diameter, between casing round platform and case lid, Sealing Device is arranged, fastening between casing round platform and the case lid with 6～8 bolts; The feeder line that is connected with base station equipment in the case passes from case lid by the waterproof through wires hole, and the coiling casing also is connected with antenna.
The beneficial effect that the present invention produces is: utilize this shape of the shape of ambient pressure as casing of bearing of cylindrical shape, can obtain maximum containing space with minimum material like this, effectively raise stock utilization.If use square box instead, the wooden partition thickness of its cabinet certainly will increase greatly.Utilize the mode of slide rail that case lid and box equipment are mentioned, the height of equipment is easy to grasp, and has made things convenient for attendant's operation.And this mode of mentioning case lid depends on the coiling method of feeder line, this method of utilizing the feeder line coiled coil to stretch has not only solved the angle of bend problem of radio frequency feed line but also has solved the problem that case lid is mentioned, and has also solved the narrow and small problem that can not arbitrarily coil line in space under the vertical shaft.
