Problems solved by technology

The firewall adopts pre-buried cable pipes and sand filling in the middle, which has the advantages of low cost and excellent fireproof performance. However, after the firewall is built, it is difficult to lay cables, and sometimes it needs to be removed and restored. During the recovery period, the tunnel cable is easily damaged, causing personnel and equipment accidents; the fire door of the cable tunnel is usually welded to the tunnel, and the fire door needs to be removed when the cable is laid, and the fire door needs to be restored by welding in the tunnel, which seriously threatens the safety of the cable operation

Embodiment 1

[0035] Embodiment 1. This embodiment provides a fire door for a power compartment of an integrated pipe gallery, which includes a tunnel body. A partition wall 11 is arranged on the inner side of the tunnel body 1 close to the inner side wall of the tunnel body 1, and a cable is arranged on the partition wall 11 A fireproof door is arranged between the partition walls 11;

[0036] The fire door includes a side door shaft 3 in contact with the partition wall 11. The upper and lower ends of the side door shaft 3 are connected to the tunnel body 1 by bolts, and a frame 29 is provided between the two side door shafts 3. A door body 5 is provided in the frame 29, a middle door shaft 2 is provided above the middle of the door body 5, a cross beam 4 is provided at the lower end of the middle door shaft 2, and the cross beam 4 is connected to the frame 29. The middle door shaft The upper end of 2 is connected with the tunnel body 1 by bolts. The frame is installed on the cross beams at ...

Embodiment 2

[0041] The second embodiment is different from the first embodiment:

[0042] Where the side door shaft 3 and the tunnel body 1 are connected, a first mounting groove 17 is provided on the tunnel body 1, and a first connecting plate 18 is provided at the bottom of the first mounting groove 17, and the first connection A first embedded rod 19 is provided on the side of the plate 18 in contact with the tunnel body 1, the end of the side door shaft 3 is in contact with the first connecting plate 18, and the end of the side door shaft 3 is provided with a number of first bolts Perforation 13, a first fixed angle iron 16 is provided on both sides of the end of the side door shaft 3, and a second bolt perforation 14 is provided on the first fixed angle iron 16 corresponding to the first bolt perforation 13, and the first bolt perforation The first fixing bolt 15 is inserted into the 13 and the second bolt hole 14, and the other side of the first fixing angle iron 16 is in contact with ...

Embodiment 3

[0048] The third embodiment is different from the first embodiment:

[0049] A first refractory plate 27 is provided on both sides of the partition wall 11, and a through hole 28 is provided on the first refractory plate 27 corresponding to the cable 8. The first refractory board wraps both sides of the partition wall to prevent the refractory filler from falling off, and reflects the aesthetics, and the through holes are convenient for cables to pass through.

[0050] The side door shaft 3, the middle door shaft 2 and the cross beam 4 are provided with second refractory plates 12 on both sides. The second refractory plates wrap other areas except the door body excluding partition walls, and refractory fillers can also be placed inside them, Play the role of partition and support.

Abstract

The invention provides an electric power bin fireproof door for a comprehensive pipe corridor. The electric power bin fireproof door comprises a tunnel body; partition walls are arranged on the positions, close to the inner side wall of the tunnel body, of the inner side of the tunnel body; cable frames are arranged on the partition walls; and a fireproof door body is arranged between the partition walls. The fireproof door body comprises side door shafts making contact with the partition walls; the upper and lower ends of the side door shafts are connected with the tunnel body through bolts;a frame is arranged between the two side door shafts and internally provided with a door main body; a middle door shaft is arranged above the middle of the door main body; a cross beam is arranged atthe lower end of the middle door shaft and connected with the frame; and the upper end of the middle door shaft is connected with the tunnel body through bolts. When cables are expanded, the fireproofdoor body and a fireproof door shaft part door can be quickly overall removed by removing fireproof door shaft bolts, after the cables are fixed, the removed fireproof door shaft bolts are recovered,and the fireproof door body and the fireproof door shaft part door can be quickly recovered; and compared with previous engineering, construction is convenient and quick, electric welding operation in the comprehensive pipe corridor is avoided, and the construction cost and operation safety risk are reduced.

Description

Technical field [0001] The invention relates to the technical field of power cable channel construction, in particular to a fire door of a power cabin of an integrated pipe gallery. Background technique [0002] With the construction of urban underground comprehensive pipe corridors, more and more cables are continuously connected to the comprehensive pipe corridors. Due to the large volume of cable loops in the urban comprehensive pipe corridors and the high voltage levels, the problem of cable fire protection has become increasingly prominent. [0003] Existing cable tunnels mostly use firewalls or fire doors to prevent fire from spreading. The firewall adopts the pre-embedded cable through pipe and the middle sand filling type, which has the advantages of low cost and excellent fire performance. However, after the firewall is built, it is difficult to lay the cable, and sometimes needs to be removed and restored. Due to the narrow space in the cable tunnel, the firewall is Duri...
