Description

A cable duct sealing device

technical field

The utility model relates to the technical field of cable duct sealing, in particular to a cable duct sealing device.

Background technique

With the rapid development of my country's economy and the gradual improvement of various urban infrastructures, higher requirements and standards have been put forward for the construction and maintenance of underground pipelines. Underground communication and power pipelines are generally made of plastic, glass steel, cement and other materials. And it is pre-buried in the underground trench dug in advance, and an artificial well is set at a certain distance as a working point for wiring, inspection, maintenance, overhaul, etc. to manage the safety of pipelines. The working point is generally made of cement as the main body of the artificial well. Since the pipes between each well are connected, if the pipes are not waterproofed and sealed or handled improperly, rainwater, sewage, silt, etc. will seep into the pipes in the long run inside, or rats and insects scurrying in and multiplying, death and rot will cause pipeline blockage, and mice eating the outer wall of the cable will cause cable breakage accidents. The fault cannot be eliminated in time due to the inability to pump water in sections, resulting in unpredictable losses. Therefore, a convenient and quick way is needed to solve this problem.

There are generally several ways to deal with it at this stage: one is the overall solution for artificial wells, which is quite expensive and not suitable for promotion; the other is to use cement, plugging king, anti-cement and other materials to seal and plug the pipeline. The disadvantage of this method is that the waterproof effect will be lost due to thermal expansion and contraction and cracking between the material and the pipe. In addition, as long as the cable is repaired and repaired, the pipe sealing material will be damaged and need to be re-sealed, which is inconvenient for future cable expansion. Since the pipeline has been fixed and blocked, the entire pipeline may be damaged if it needs to be restored; third, the existing inflatable cable duct sealing bag is a better solution, but the disadvantage is that the inflatable sealing bag does not have the effect of fire prevention and flame retardant , can not meet the needs of the cable communication industry for the safe production of the pipe network. In addition, the inflatable air bag is blocked at the pipe port to prevent water from flowing into or out of the pipe. If the cable is soaked in water for a long time, it will bring great hidden danger to the safe operation of the cable.

A strip-shaped airtight bag-like body, a polymer modified rubber tape is provided along the winding direction in the middle of the front and back of the main body of the inflatable bag, and the surface of the polymer modified rubber tape is bonded and fixed with an isolation film The two sides of each polymer modified rubber tape are symmetrically provided with waterproof foam tape, and the upper end of the main body of the inflatable bag is provided with a self-sealing silicone inflation nozzle. The two ends of the main body of the inflatable bag are respectively bonded and fixed with a PE water pipe between the polymer modified rubber tapes protruding from the two ends.

As an improvement, the ends of the two PE water pipes on the same side are provided with movably connected transparent visible hoses.

(3) Beneficial effects

Compared with the prior art, the utility model has the following beneficial effects:

1. Easy and fast installation, flexible disassembly and assembly, without destroying the original pipeline.

2. The scope of application is wider. Large-diameter pipelines can be installed with or without cables, and the irregularities of the inner wall of the pipeline will not be affected.

3. Wide range of applications, not affected by temperature.

4. The PE pipe structure at both ends solves the problem of drainage of the cable pipe, and the water level can be observed through the transparent visible hose installed on the PE pipe.

5. The main body of the inflatable bag is made of fire-resistant, flame-retardant and corrosion-resistant materials, which greatly increases the fireproof performance of the product.

6. The setting position of the self-sealing silicone inflation nozzle and the setting of the isolation film can make the utility model reusable by inflation.

detailed description

In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model, and are not intended to limit the utility model.

A cable duct sealing device as shown in Fig. 1, Fig. 2 and Fig. 3 includes an air bag main body 1, and the air bag main body 1 is a rollable and long coil made of flame-retardant and fire-resistant materials. The strip-shaped sealed bag-shaped body can meet the requirements of V-0 fire protection. In the middle of the rollable front and back of the inflatable bag main body 1, a polymer modified rubber tape 2 is arranged along the winding direction. The surface of the rubber tape 2 is bonded and fixed with an isolation film 3, and the two sides of each polymer modified rubber tape 2 are symmetrically provided with a waterproof foam tape 4, and the upper end of the air bag main body 1 is provided with a self-sealing silicone inflating nozzle 5, The polymer modified rubber tapes 2 located on the front and back of the air bag main body 1 are all overhanging at both ends of the air bag main body 1, and a PE water pipe 6 is bonded and fixed between the polymer modified rubber tapes 2 extending out at both ends.

Wherein, the same-side ends of the two PE water pipes 6 are provided with movably connected transparent visible hoses 7 .

A cable duct sealing device mentioned in the utility model, in specific use, select the front or back side of the air bag main body 1, fit it on the cable and stuff it into the cable duct, and inflate it through self-sealing silica gel The nozzle 5 can inflate the air bag main body 1, and the inflatable bag main body 1 after inflation can fill the large space in the tube, and the polymer modified rubber tape 2 located on both sides of the air bag main body 1 can fill gaps and bond waterproof In addition, the isolation film 3 is fixed on the surface of the molecularly modified rubber tape 2 by a film coating process, which can prevent the polymer modified rubber tape 2 from bonding with cables and wire tubes, and can make the main body of the inflatable bag 1 reusable, while ensuring Sealing, the waterproof foam tape 4 located on both sides of the polymer modified rubber tape 2 improves the effective range of gap filling and bonding of the polymer modified rubber tape 2, and also plays a certain role in waterproofing.
