Problems solved by technology

[0003] However, the current steam cross-linking room on the market still has defects in use. First, the steam inside the room is unevenly distributed around the cable, resulting in poor cross-linking effect of the cable. Secondly, the heat absorbed during the cross-linking process of the cable will The steam is converted into water droplets, and the water droplets accumulate in the sealed room, which is easy to affect the cable cross-linking process, and it is difficult to adjust the steam pressure inside the room
Finally, most of the houses have a one-piece structure, which makes it difficult to transfer the location, making it difficult to reuse the house, and the insulation layer in the house wall is prone to loosening, causing the steam in the house to dissipate heat quickly, and more resources are required

Embodiment 1

[0039] Such as Figure 1 to Figure 4As shown, the steam cross-linking room for power cable cross-linking in this embodiment, a steam cross-linking room for power cable cross-linking, includes a room body 1, a controller 2 is installed on the front surface of the room body 1, and the interior of the room body 1 Both sides are provided with a support frame 3, and a fixed pipe 7 is fixed on the inner side of the support frame 3, and several air outlet pipes 8 are connected to one side of the fixed pipe 7, and an air guide hose 6 is connected to one side of the fixed pipe 7 , the air outlet pipe 8 is provided with a number of spray holes 9, the steam is passed into the air guide hose 6, the steam will enter the air outlet pipe 8 through the fixed pipe 7, and then spray out from the spray holes 9, so that the steam enters the room evenly body 1, in order to ensure that the cable cross-linking operation can be completed stably, the inside of the support frame 3 is located at the fou...

Embodiment 2

[0044] The structure of the steam cross-linking room for power cable cross-linking in this embodiment is basically the same as that of the steam cross-linking room for power cable cross-linking in Embodiment 1, the difference is that a water storage frame 15 is fixed at the inner bottom of the room body 1 A support block 17 is fixed above the inside of the water storage frame 15, a grid plate 16 is placed on the top of the support block 17, the top of the grid plate 16 is flush with the top of the water storage frame 15, and the outside of the house body 1 is provided with Water storage cylinder 21, connecting pipe 18 is connected between water storage cylinder 21 and water storage frame 15, heat will be absorbed during the cable cross-linking process, and then steam will be converted into water droplets, when the water droplets fall, they will directly pass through the grid plate 16 Enter the inside of the water storage frame 15, and then the water droplets will enter the wate...

Embodiment 3

[0050] The structure of the steam cross-linking room for power cable cross-linking in this embodiment is basically the same as the structure of the steam cross-linking room for power cable cross-linking in Example 1, the difference is that the room body 1 is spliced ​​by six boards through the connecting mechanism A door is installed on one of the boards so that the staff can go in and out; Located inside the rectangular frame-like structure, the joints of the four horizontal plates 30 and the joints of the horizontal plates 30 and the support plate 27 are all welded and fixed; On one side of the board 30, several fixed posts 25 on one of the boards are all inserted into the inside of the adjacent board, and the outside of the fixed post 25 is threadedly connected with a fixed bolt 24, because the room body 1 is connected by six boards and Mechanisms are spliced ​​together, therefore, the disassembly and assembly operation of the room body 1 can be quickly completed, and the r...

Abstract

The invention discloses a steam crosslinking room for power cable crosslinking, and relates to the technical field of steam crosslinking rooms, the steam crosslinking room comprises a room body, a controller is mounted on the front surface of the room body, supporting frames are arranged on the two sides in the room body, a fixing pipe is fixed on one side in each supporting frame, a plurality of air outlet pipes are connected to one side of each fixing pipe, and the air outlet pipes are connected to the other side of each fixing pipe. A plurality of spraying holes are formed in the air outlet pipe, guide holes are formed in the four corners of the interior of the supporting frame, guide columns penetrate through the guide holes, the two ends of the guide columns are fixed to the two sides of the interior of the room body correspondingly, and under the combined action of a motor, a gear and a toothed plate, the two ends of the guide columns are fixed to the two sides of the interior of the room body correspondingly; the motor, the connecting plate and the supporting frames can integrally slide along the guide columns, so that the positions of the two supporting frames in the room body are adjusted, steam is closer to a cable, the temperature around the cable is increased in a short time, and meanwhile the uniformity of the steam around the cable is improved.

Description

technical field [0001] The invention relates to the technical field of a steam cross-linking room, in particular to a steam cross-linking room for electric cable cross-linking. Background technique [0002] Silane cross-linked cables have the advantages of good heat resistance, high strength, and good creep resistance. They are widely used in the insulation layer of power cables. The equipment with high safety is widely used by cable manufacturers. [0003] However, the current steam cross-linking room on the market still has defects in use. First, the steam inside the room is unevenly distributed around the cable, resulting in poor cross-linking effect of the cable. Secondly, the heat absorbed during the cross-linking process of the cable will The steam is converted into water droplets, and the water droplets accumulate in the sealed room, which easily affects the cable cross-linking process, and it is difficult to adjust the steam pressure inside the room. Finally, most ...
