Detailed Description
The utility model will now be described in further detail with reference to the accompanying drawings.
As shown in figures 1-2, a cable threading pipe with cooling function comprises a double-layer galvanized steel pipe, an air inlet pipe 9, an air tank 5 and an air outlet pipe 8, wherein the double-layer galvanized steel pipe comprises an inner layer 3 and an outer layer 2, a supporting frame 7 is welded between the inner layer 3 and the outer layer 2 to ensure that the relative positions of the inner layer 3 and the outer layer 2 are kept unchanged, two ends of the double-layer galvanized steel pipe are sealed by hollow plugs, two plugs at the two ends are respectively connected with an intermediate joint 1, the front end of the air inlet pipe 9 is communicated with a cooling compressed air source, the rear end of the air inlet pipe 9 is connected with the inlet of the air tank 5, the outlet of the air tank 5 is connected with one end of the air outlet pipe 8, and the tail end of the air outlet pipe 8 is connected with the double-layer galvanized steel pipe through the intermediate joint 1, so that cooling compressed air can pass through a channel between the inner layer and the outer layer of the double-layer galvanized steel pipe.
The air outlet pipe 8 is provided with a pressure gauge 6, and the pressure gauge 6 is arranged at the outlet of the air tank 5.
The regulating valve 4 is arranged at the front end of the gas tank 5 and can be used for regulating the flow of cooling compressed air, and the valve can be closed when equipment is overhauled.
The plug is hollow to facilitate passage of the power line therethrough.
The plugs at the two ends of the double-layer galvanized steel pipe are respectively provided with an intermediate joint 1, one of which is connected with an air outlet pipe 8 and is used as an air inlet for cooling compressed air, and the other is used as an air outlet for compressed air.
The air gap between the outer layer 2 and the inner layer 3 of the double-layer galvanized steel pipe is about 5 mm.
The inner and outer pipe diameters of the double-layer galvanized steel pipe can be specifically determined according to the number of laid cables.
The working method of the utility model comprises the following steps: the adjustable valve 4 is opened, cooling compressed air enters the air tank 5 through the air inlet pipe 9, and then is conveyed to the air gap between the outer layer 2 and the inner layer 3 of the galvanized steel pipe through the air outlet pipe 8, so that the compressed air in the pipe network can be effectively utilized to continuously circulate in the air gap to cool the threading pipe, and the temperature of a cable inside the threading pipe is ensured not to be too high.
