Technical Field

The invention relates to the technical field of substation equipment plugging, in particular to a nylon hasp combined sealing device for plugging cable holes of a cabinet screen in an all-dimensional manner.

Background

At present, the shutoff of cables such as case, cabinet, screen, electric wire hole, technical measure such as mostly adopt fire prevention mud, cement, WQBZ inflatable pipe seal bag carries out the shutoff, it is more to have a construction process, the input cost is great, the shutoff effect is general, the dismouting, it is complicated to maintain, fire prevention, smoke protection, it is dustproof, prevent the function difference of toy, especially when meetting maintenance and new installation, need be to its shutoff again, waste time and energy, resources are wasted, the shutoff quality is difficult to guarantee.

Wherein: 1. The sealing by adopting the fire clay technology has the following defects: (1) the fireproof mud is most easily influenced by the change of the environmental temperature to block the quality and the effect: when the environmental temperature is too high, the fireproof mud can soften and overflow, so that holes are not tightly blocked; when the environmental temperature is too low, the fireproof mud can be hardened and fall off to form holes; the effects of smoke prevention, fire prevention, dust prevention and small animal prevention are poor; (2) the requirement of the size of the fireproof mud plugging hole has great limitation: the plugging of small-size cabinet screen hole has the effect, but can not effectually carry out the shutoff to the great hole of cabinet screen, must adopt to add fire-resistant welt and other effectual safeguard procedures and fix the back, just can adopt the shutoff of fire prevention mud again after will making cable, electric wire hole reduce.

2. Adopt WQBZ inflatable pipe sealing bag technique to carry out the shortcoming that the shutoff exists: (1) the problem of tight plugging among gaps of a plurality of cables or wires cannot be effectively solved; (2) the construction is complicated, when meetting cable, electric wire and salvageing, maintenance and change, need make again and shutoff, wastes time and energy, and the construction process is loaded down with trivial details, dismouting, maintenance are complicated. (3) The WQBZ inflation type pipeline sealing bag technology is poor in hole effects of boxes, cabinets, screens and the like, and the wall surfaces of the holes of the boxes, the cabinets, the screens and the like are made of stainless steel or PVC materials with the thickness of 2mm-5 mm.

3. The method adopts the technology of fireproof material synthesized by mixing cement and inorganic for plugging, and has the following defects: effective shutoff is carried out to the hole etc. that is only applicable to the firewall, the floor of great hole, wears the wall, but to the shutoff effect special poor of business turn over cable, electric wire hole such as case, cabinet, screen, the reason: (1) most of the cable and wire inlet and outlet holes such as boxes, cabinets, screens and the like are made of stainless steel and insulating environment-friendly materials, the four walls of the holes are thin and are generally 2mm-5mm, and the holes cannot be effectively and fixedly plugged by using cement inorganic mixed fireproof materials; (2) the problems of moisture regain, water vapor and the like are easy to occur; (3) the construction is complicated, when meetting cable, electric wire and salvageing, maintenance and change, need make again and the shutoff, wastes time and energy, and the resource is wasted, and the construction process is loaded down with trivial details, dismouting, maintenance are complicated.

The patent with the publication number of CN202503234U discloses a plugging device for cable holes of an underground substation, which comprises a water plugging connector in the cable hole, a cable in the water plugging connector and a cement plugging layer of a hole, wherein a sealing expansion assembly is arranged on the outer side of the water plugging connector. The plugging of the cable hole and the cutting of the water leakage channel in the cable body are changed from separate treatment to simultaneous treatment, and the primary protection is changed into multiple protection; and sealing and expanding assemblies are adopted to seal and fill gaps between the cables and the hollow holes.

The patent with the publication number of CN203836407U discloses a cable hole plugging device for plugging a cable hole penetrating through a reinforced concrete wall, wherein a cable is arranged in the cable hole, the plugging device comprises an engineering plastic part and a rubber and plastic sealing waterproof material layer, the engineering plastic part is sleeved outside the cable and is connected with the reinforced concrete wall, and the rubber and plastic sealing waterproof material layer is arranged between the engineering plastic part and the cable, between the engineering plastic part and the reinforced concrete wall.

Above-mentioned two kinds of plugging device all have the shutoff insecure, and the construction is complicated, and the cable is changed, and the maintenance is inconvenient, wastes time and energy etc. not enough, and is applicable to the hot wall that prevents of great hole, wears wall hole etc. and is not suitable for cable holes such as case, cabinet.
