Detailed Description
In order that the present invention may be more readily and clearly understood, a more particular description of the invention briefly described above will be rendered by reference to specific embodiments that are illustrated in the appended drawings.
The state has a clear regulation on the fixation of the electric installation engineering cable, and when the cable of 35kV or below is vertically laid, the proper number of positions of the upper end, the lower end and the middle part are provided with fixed positions. The existing parts for fixing the cable are generally selected from flat steel clamps, nylon cable ties, plastic-plated metal cable ties and the like. When the cable is fixed by the clamp, the clamp force of the clamp on the cable is different due to the feeling of constructors, and the cable sheath and the cable insulation are easily damaged due to overlarge clamp force, so that the service life of the cable is influenced; when the cable is fixed by adopting a nylon cable tie, a plastic-plated metal cable tie and the like, the holding force of the cable with the small section can basically meet the requirement, but the holding force of the cable with the large section can hardly meet the requirement, and the cable cannot be fixed, locked and supported.
Referring to fig. 1 and fig. 2, in view of this, the present embodiment provides a vertically-laid armored photovoltaic cable, which includes a cable body 1 and a plurality of laying fixtures mounted on the cable body 1. A plurality of lays the mounting and evenly arranges along cable body 1's axis direction, and cable body 1 lays the mounting through a plurality of and realizes laying perpendicularly.
Specifically, each laying fixture comprises a set of inner and outer clamping plates 2, 3. The inner clamping plate 2 is provided with a laying mounting hole, and the inner clamping plate 2 is mounted on a wall body and the like through the mounting hole. A clamping groove 4 with a semicircular cross section is formed in one side of the inner clamping plate 2 opposite to the outer clamping plate 3. Interior cardboard 2 and outer cardboard 3 dock outside cable body 1 back, and the inner wall of draw-in groove 4 is laminated with cable body 1's outer wall mutually in interior cardboard 2 and outer cardboard 3.
Wherein, be provided with spacing lug 5 on the outer wall of cable body 1, all correspond on the inner wall of interior cardboard 2 and outer cardboard 3 and offer shape and spacing recess 6 of spacing lug 5 assorted. Interior cardboard 2 docks at cable body 1 outer back with outer cardboard 3, and spacing lug 5 is located spacing recess 6, and the gliding phenomenon can be avoided appearing in cable body 1 under the effect of dead weight or other external forces to spacing lug 5 and spacing recess 6 limiting displacement to fix and support cable body 1 effectively. The limiting projection 5 is an annular projection coaxially arranged on the outer wall of the cable body 1, and the annular projection is matched with the annular groove to enable the cross section of the cable body 1 to be uniformly stressed.
The preferred all is provided with a plurality of cyclic annular lugs on every cable body 1 that lays the mounting cladding, and this a plurality of cyclic annular lug sets up along cable body 1's length direction equidistance in proper order, has seted up quantity, shape and cyclic annular lug assorted spacing recess 6 on the inner wall of cardboard 2 and outer cardboard 3 including correspondingly. A plurality of cyclic annular lugs are located corresponding spacing recess 6 respectively, have further improved the fixed and support effect to cable body 1.
