Abstract

The utility model relates to a submarine cable degassing chamber and belongs to the cable degassing chamber. Chamber upper cover is arranged on the top of chamber wall; the top of the chamber upper cover is fixedly connected with upper cover lifting lugs; winding stand columns are positioned in the center of the chamber; fan heating devices are fixedly connected outside the chamber wall; two oppositely-arranged semi-circle hot air ducts are arranged on the ground inside the chamber wall and are communicated with the two fan heating devices respectively; each semi-circle hot air duct is provided with an air-out hole; each winding stand column is provided with an air-in hole; one end of an exhaust duct is communicated with the inner side of the winding stand column, and the other end is communicated with the fan heating device; the chamber wall is internally provided with a rock wool heat-insulation layer; and the chamber wall is provided with an access door and an exhaust gas discharge connection port. The advantages of the submarine cable degassing chamber are that: the structure is novel; the processed cable does not contain methane gasses; and thus the cable can be guaranteed to be used safely in the future.

Description

Submarine cable deaeration chamber

Technical field

The utility model is for removing the special equipment of the methane gas that submarine cable manufacture process produces.

Background technology

Cable is after just having manufactured at present, in the insulation sheath of cable, contain a large amount of methane gass, like this without the cable of processing as used in electric power transfer, while particularly using as high-tension cable, methane gas is wherein easy to make cable to produce micropore, cable life is shortened, and the safety of electric power transfer in serious threat, to carrying out electric power transfer safely, brings hidden danger.But because special big-length, the heavy weight characteristic of submarine cable makes the domestic and international poor effect of degassing for crosslinked polyetylene insulated submarine cable deaeration chamber now, significantly extended the production cycle of submarine cable, reduced production efficiency.

Summary of the invention

The utility model provides a kind of submarine cable deaeration chamber, to solve the poor effect of degassing existing at present, the production cycle that causes significantly having extended submarine cable, has reduced the problem of production efficiency.

The technical scheme that the utility model is taked is: chamber body upper cover is positioned at the top of chamber body wall, on the body of chamber, tops is fixedly connected with upper cover hanger, coiling column is positioned at body center, chamber, blower fan heater is connected with chamber body wall external stability, two semicircle warm-air pipes staggered relatively are positioned on the ground of body wall inside, chamber, and be communicated with two blower fan heaters respectively, on this semicircle warm-air pipe, there is exhaust vent, on coiling column, there is fresh air inlet, exhaust duct one end and coiling column internal communication, the other end is communicated with blower fan heater, there is rock wool heat-preservation floor body wall inside, chamber, on the body wall of chamber, there are access door and toxic emission connector.

The utility model advantage is novel structure, by mode of heating, remove the methane gas in cable, heating system design is reasonable, airduct arrangement is served suction under being, diagonal angle is arranged, so more be conducive to gas communication, make chamber temperature balanced, by circulation hot gas, heat, waste gas is had to exhaust outlet, guaranteed the safety in production process.Make in the cable after processing not methane-containing gas, guarantee the safety in using from now on.

Embodiment

Chamber body upper cover 2 is positioned at the top of chamber body wall 3, on the body of chamber, tops is fixedly connected with upper cover hanger 1, coiling column 7 is positioned at body center, chamber, blower fan heater 4 is connected with chamber body wall external stability, two semicircle warm-air pipes 5 staggered relatively are positioned on the ground of body wall inside, chamber, and be communicated with two blower fan heaters respectively, on this semicircle warm-air pipe, there is exhaust vent 6, on coiling column, there is fresh air inlet 8, exhaust duct 9 one end and coiling column internal communication, the other end is communicated with blower fan heater, there is rock wool heat-preservation floor 10 body wall inside, chamber, on chamber body wall 3, there are access door 11 and toxic emission connector 12.

During use, the submarine cable that will remove methane from the upper cover of opening around to deaeration chamber coiling column, close upper cover, open blower fan heater, blower fan is by semicircle warm-air pipe to the indoor hot gas that is blown into, and hot gas rises, and the fresh air inlet from coiling column enters coiling column, through exhaust duct, get back to heater, when indoor exhaust air is too much, by toxic emission connector, be discharged in pipeline.

Claims

1. a submarine cable deaeration chamber, it is characterized in that: chamber body upper cover is positioned at the top of chamber body wall, on the body of chamber, tops is fixedly connected with upper cover hanger, coiling column is positioned at body center, chamber, blower fan heater is connected with chamber body wall external stability, two semicircle warm-air pipes staggered relatively are positioned on the ground of body wall inside, chamber, and be communicated with two blower fan heaters respectively, on this semicircle warm-air pipe, there is exhaust vent, on coiling column, there is fresh air inlet, exhaust duct one end and coiling column internal communication, the other end is communicated with blower fan heater, there is rock wool heat-preservation floor body wall inside, chamber, on the body wall of chamber, there are access door and toxic emission connector.
