Embodiment
Followingly the present invention is described in further detail with reference to accompanying drawing.
With reference to Fig. 1 and Fig. 2, feed of the present invention cabin power line and holding wire bindiny mechanism mainly are made up of cable wire and lead carriage, and this cable wire is connected the top of two support towers 3 of flexible antennas, as the support cable wire 12 of feed cabin power line and holding wire; This lead carriage 14 is provided with five, be installed in and support on the cable wire 12, these lead carriages can support on the cable wire at this and slide, but last lead carriage, that lead carriage that is the rightmost side among Fig. 2 is affixed with the support cable wire, and power line, signal line group 13 are connected to the ground observing and controlling chamber through support tower 3.
Referring to Fig. 3, lead carriage 14 of the present invention mainly is made up of limit steel cable 17, guard shield 18, top flute profile pulley 19, bottom flute profile pulley 20, pulley spindle 21, limit steel cable securing member 22, power line, holding wire securing member 23, power line 24, holding wire 25.Wherein:
Top flute profile pulley 19, bottom flute profile pulley 20 support by the pulley spindle 21 that is fixed on the guard shield 18, support on the cable wire 12 horizontally slipping at lead, realize change in location.
When being connected feed of the present invention cabin power line and holding wire mechanism in the large-scale flexible antenna structure shown in Figure 1, at first in this type flexible antennas, select two support towers 3 by the distribution circle diameter; The top that connects these two support towers 3 again with the cable wire of suitable intensity, as the support cable wire 12 of feed cabin power cable and signal cable, this rope diameter designs according to the weight of the cable of concrete carrying; Support the quantity of determining to need to install lead carriage 14 on the cable wire 12 according to feed cabin 6 range of movement at this then, present embodiment has used five lead carriages, preceding four of these lead carriages all can horizontally slip on support cable wire 12, last lead carriage is designed to and to support cable wire affixed, and power line and holding wire are connected to the ground observing and controlling chamber at last through support tower.
Because when move in its range of movement 15 in feed cabin 6, the length of power line, holding wire changes along with the change in location in feed cabin 6.Thereby whether the length of this section lead suitably be related to the problem that can feed cabin 6 operate as normal, and promptly lead is long causes waste, and the too short feed cabin 6 of causing of lead is when move in the distant place, and lead can be broken.The present invention adopts mode shown in Figure 2 for this reason, power line 24 between each lead carriage, holding wire 25 are arranged to the mode of dangling, the lead group 13 of first carriage that is connected with the feed cabin also is set to the mode of dangling, with dangling of lead as the deposit of feed cabin at its range of movement inside conductor, to satisfy the needs of feed motion, promptly satisfy following several moving situations in feed cabin:
1. when its range of movement 15 centers were left in feed cabin 6, when moving as the position, the lower left corner of feed cabin range of movement 15 frame of broken lines in Fig. 2, the lead group 13 among feed cabin 6 and Fig. 2 between the leftmost lead carriage was stretching.
When feed cabin 6 when above-mentioned direction continues to move, and the limit steel cable 17 that is listed in the lead group 13 is tightened up, spur lead carriage 14 this moment, when it is slided left on supporting cable wire 12, each lead carriage 14 scatters successively, correspondingly, the lead group 13 of dangling between each lead carriage is also drawn back successively.
3. when feed cabin 6 during to the motion of its range of movement 15 centers, feed cabin 6 is to the moving lead carriage 14 of pulling back, make lead carriage 14 support slip to the right on the cable wire 12, each lead carriage 14 closes up successively, correspondingly, the lead group 13 that 14 of each lead carriages draw back is also dangled successively and is closed up, and is in automatic deposit state.
Follow the principle of above feed cabin 6 motions, generally speaking, conductor length between the Far Left lead carriage 14 among feed cabin 6 and Fig. 2 to be stopped in advance, this length should satisfy at least and equals power line, the holding wire lower central position to feed cabin range of movement 15, and reserve due rich amount, to support the proper motion in feed cabin 6.
According to above-mentioned design philosophy, be in the flexible antenna structure of 25m at a bore 50m, six roots of sensation column height, use above-mentioned feed cabin power line and holding wire bindiny mechanism to experimentize.Wherein, the rope diameter of two support towers of cross-over connection is 8mm, uses 11 lead carriages, and the range of movement in feed cabin is the cylindrical space of 25m * 12m (diameter * highly), and actual motion is respond well.
