Abstract

The invention relates to the field of cable sealing and fixing, in particular to a vertical cable clamping reducing clamping sleeve and a vertical cable protection frame. The caliber of the upper end of the conical sleeve is larger than that of the lower end, the outer diameter of the upper end of the conical sleeve is larger than that of the lower end of the conical sleeve, and the reducing fitting ring is conical. Because conical sleeve and reducing laminating circle are whole to be the toper, consequently, receive the gravity of setting at the cable or pipeline of reducing laminating circle inner circle, can produce radial reaction force, lead to the axial gravity that bears the big more, radial reaction force is big more. Therefore, the extrusion force between the reducing fit ring and the conical sleeve which are arranged in a stacked mode is in direct proportion to the gravity of the cable and the gravity of the pipeline. Once the reducing fit ring slides axially, the larger the sliding degree is, the tighter the fit between the reducing fit rings is, and the larger the friction force is. The gliding of vertical fixed cable and pipeline can be effectively prevented to and the gliding between the reducing laminating circle of stack setting. The vertically arranged cables are effectively protected.

Vertically arranged cables are often used in wind power plants, where the vertically arranged cables are used to transport electrical energy in a vertical direction. The fixing frame is required to be installed between the vertically arranged cable and the equipment so as to transversely fix the cable, particularly in the wind power generation equipment, the cable can easily shake along with the rotation of the power generation equipment, and therefore a sealing sleeve is required to be arranged at the position, corresponding to a cable through hole, of the fixing frame. Each vertical cable in the wind power generation equipment weighs about 160kg, the existing sealing sleeve is mostly in a straight cylinder shape, and in order to adapt to cables with different diameters, a group of edge diameter stripping pieces are arranged in the sealing sleeve in an overlapped mode. Due to the gravity action of the cable, on one hand, the cable is easy to slide in the sealing sleeve, and on the other hand, the stripping sheet arranged in the sealing sleeve can also axially slide to cause errors, and is easy to wear and even has the risk of falling. And therefore cannot accommodate sealing and securing of vertical cables.
