Description

cable duct sealer

technical field

The utility model relates to a cable duct sealer.

Background technique

With the advancement of science and technology in our country and the rapid development of electric power and communication, since the ground and high-altitude erection of wires and cables not only affects transportation but also occupies a lot of space, it is gradually converted to underground pipelines to install national electric power, communication and other wires and cables. Usually these places are in a watery or humid environment, therefore, this requires higher sealing and waterproof performance of the cable.

At present, cement or fire-proof mud is mostly used for sealing underground cable ducts. Cement seals need to transport materials in advance and need a water source. Stirring and grouting are slow to solidify, and stones and sand are easy to cause damage to cables and pipes; fire-proof mud needs water to be softened and squeezed at 50°C. Press, easy to peel off. Their common disadvantages are: non-recyclable and difficult to clean; on the one hand, the cement seals the cables in the pipe, so that when the cables need to be replaced for future expansion, the entire cable channel will be scrapped because it is difficult to pull the original cables, and it is impossible to Secondary utilization; on the other hand, the leakage resistance of the cement material itself is not good, and the long-term water pressure penetration makes it difficult to keep the sealing surface in good condition without cracks and water seepage, so that both sides or a certain part of the cable duct The side is in a humid and watery environment for a long time, and when it is necessary to carry out construction on this location, it is often necessary to pump water and dehumidify first, and then the construction work can be carried out, wasting a lot of time and labor.

Contents of the invention

The purpose of the utility model is to solve the shortage of cable duct sealing in the prior art, and provide a cable duct sealer, which has good sealing and waterproof performance, can also prevent fire and mice, and can be used repeatedly.

Technical solutions

A cable duct sealer, comprising a straight bag body with a sealed inner cavity, a waterproof adhesive strip is arranged on the upper surface of the bag body, an adhesive strip is arranged on the lower surface of the bag body; There is an inflatable port, and the inflatable port is provided with an air nozzle base and an air nozzle arranged on the air nozzle base, and the air nozzle communicates with the sealed inner cavity of the bag body through the inflatable port; the bag body is a layered structure, sequentially from outside to inside It is composed of a fireproof layer, a rodent-proof layer and a composite material layer.

The fireproof layer is a high-temperature fireproof cloth, which can withstand open flames above 800°C and can effectively prevent open flames from passing through the well.

The anti-rodent layer is a wire mesh, which can effectively prevent the mice from being bitten when biting the inflatable device, so as to ensure the effectiveness of the device.

The composite material layer is compounded by high-performance plastic nylon plus pure polyethylene and alloy titanium foil through co-extrusion with glue, adhesive resin and other polymer materials.

The utility model has the beneficial effects of simple structure, simple operation, good sealing and waterproof performance, fireproof and mouseproof, and can be used repeatedly, which is beneficial to reduce the cost.

Detailed ways

Below in conjunction with accompanying drawing and specific embodiment the utility model is further described.

As shown in Fig. 1, Fig. 2 and Fig. 3, the cable duct sealer of the present invention includes a straight bag body 1 with a sealed inner cavity, and a waterproof rubber strip 2 is provided on the upper surface of the bag body 1, and the bag body The lower surface of 1 is provided with an adhesive strip 3; the side of the bag body 1 is provided with an air filling port, and the air filling port is provided with an air nozzle base 4 and an air nozzle 5 arranged on the air nozzle base 4, and the air nozzle 5 passes the inflation The mouth communicates with the sealed inner cavity 9 of the bag body 1; the bag body 1 is a layered structure, which is composed of a fireproof layer 6, a rodent-proof layer 7 and a composite material layer 8 sequentially from the outside to the inside. In this embodiment, the fire-proof layer is a high-temperature fire-proof cloth, which can withstand open flames above 800°C; the mouse-proof layer is a wire mesh, which can effectively prevent mice from being bitten when they bite the inflatable device The composite material layer is compositely formed by high-performance plastic nylon plus pure polyethylene and alloy titanium foil through co-extrusion with glue, adhesive resin and other polymer materials.

When in use, roll the straight bag body 1 from one end to the cable tube through the adhesive strip 3, and roll it to the other end, then open the air nozzle 5, and enter the airtight cavity 9 inside the bag body through the air nozzle 5 Inject high-pressure inert gas to inflate the bag body 1. After the bag body 1 expands, the waterproof adhesive strip 2 on the upper surface is firmly attached to the pipe wall and the cable, and the excellent fluidity and adhesiveness of the waterproof adhesive strip will fill the air. Various gaps between the device and cables and pipes, thus forming a good waterproof sealing effect. During maintenance or construction, it can be taken out after only opening the gas nozzle 5 to deflate, and the operation is convenient. The air nozzle of the utility model can deflate or replenish air when the air pressure of the device is too high or too low to ensure that the device operates well, or it can deflate and recover after the device completes the sealing task, which can be used for the next time The plugging and sealing task effectively reduces the cost of pipeline plugging and improves the efficiency of power grid operation.

The cable duct sealer of the utility model has the advantages of simple structure, simple operation, good sealing and waterproof performance, fire and mouse prevention, and can be used repeatedly, which is beneficial to reduce costs. The cable duct sealer is suitable for various plastics, steel, Concrete and other pipes can effectively prevent water or rat ants or corrosive substances from flowing into the pipe holes and causing damage to cables and wires.
