Description

Cable tube plugging device with strong sealing performance

Technical Field

The invention mainly relates to the field of cable tube plugging, in particular to a cable tube plugging device with strong sealing performance.

Background

The cable pipeline sealing is mainly used for preventing sewage and rainwater from flowing into the pipeline, so that the cable is in dangerous operation in water after being soaked for a long time, and the sewage and the rainwater are prevented from flowing through the pipeline to endanger the operation safety of an adjacent inspection well or a transformer substation/switching station; the sewage is prevented from bringing sediment and garbage into the cable duct to influence the line inspection and maintenance in the later period; the small animals are prevented from entering the cable pipeline, biting and damaging the cable, and propagating channeling in the pipeline. The existing cable pipeline plugging mode is to plug by using the expansion of a plugging device, generally, rubber materials are adopted, the section of the cable pipeline is filled by the internal and external expansion of rubber stress, but the plugging compactness of the rubber expansion is limited, when the plugging device is eroded by rain water due to heavy rain, the plugging device is easy to loosen, the service life of the plugging device is short, water waves are eroded for a long time to cause water seepage at the plugging position, and the plugging device is easy to damage.

In the prior art, the patent of the invention patent application publication No. CN113972606A discloses an impact-resistant cable pipe plugging device, which is used for solving the problems that the plugging compactness of the existing plugging device is limited and the service life of the plugging device is not long enough; the outer layer sealing piece comprises a lower stop plate, and an outer layer sealing sleeve is arranged at the top end of the lower stop plate; a plurality of bolts penetrate through the upper stop plate and the lower stop plate, and the middle parts of the bolts are rotationally connected with a mounting ring; the inner sealing sleeve is provided with the subassembly that shocks resistance with the inside cavity of outer sealing sleeve, and the subassembly that shocks resistance includes the dead lever, and the dead lever setting is equipped with movable cup post in last limiting plate bottom, and the cover is equipped with compression spring on the dead lever, and movable cup post bottom is provided with the swivel mount, and the swivel mount is articulated with two connecting rods, and movable groove has all been seted up to the collar both sides, and the activity inslot card is equipped with fan-shaped extrusion piece, and fan-shaped extrusion piece upper end of connecting rod articulates.

The technical scheme solves the problems in the background technology to a certain extent, but the shock-resistant assembly structure adopts a mechanical structure, so that the structure is complex, the cost is high during production, manufacture and use, the technical scheme still adopts expansion type plugging at all, the tightness of the sealing scheme depends on the smoothness and flatness of the inner wall of the cable duct, and the sealing property of the cable duct can be reduced when the cable duct is locally sunken or uneven, so that water enters the cable duct;

in the prior art, a technical scheme of filling expansion glue is adopted to plug a cable tube, such as the technical scheme disclosed in patent publication number CN 110295024B: a cable pipe plugging agent and a use method thereof are provided, wherein the cable pipe plugging agent comprises A, B components, and the component A comprises the following components in parts by weight: 70-80 parts of dihydroxyl polyether; 2-4 parts of chain extender; 5-8 parts of cross-linking agent; 1 to 1.5 portions of organic silicon surfactant; 1.5 to 2 parts of water and 1 to 1.5 parts of amine trimerization catalyst; the component B comprises diphenylmethane diisocyanate (MDI) and polyphenyl polymethylene polyisocyanate (PAPI) according to the mass ratio of 90: (8-10) and mixing the materials in proportion; A. the proportion of the two components is as follows by mass ratio: 100: (70-80). The invention adopts the expansion type cable pipe plugging agent to block the cable pipe in a sectional way, integrates the functions of water resistance, plugging and theft prevention, and can achieve the multiple effects of permanent sealing, corrosion resistance, rat resistance and ant damage resistance.

According to the technical scheme, the cable tube is permanently plugged by the expansion adhesive, but the position of the cable in the cable tube needs to be considered during construction, the cable must be kept centered in the cable tube to ensure that the expansion adhesive is distributed between the cable and the cable tube for plugging, if the position of the cable in the cable tube is not centered, for example, the cable is contacted with the inner wall of the cable tube, the contact part of the cable and the inner wall of the cable tube cannot be effectively glued, and when the cable is shifted or vibrated, the contact part of the cable and the inner wall of the cable tube can generate cracks, so that the sealing of the cable tube is invalid. Therefore, in summary, the existing plugging device has the problem of poor sealing, and the problem of sealing failure during later use is easy to occur due to the adoption of the expansion glue for plugging.
