Abstract
The utility model discloses a cable channel working well, which is applied to a power communication system. The cable channel working well comprises a working well main body and a manhole leading to the working well main body, wherein the manhole is positioned in one side of the working well main body; a vertical ladder leading to the inside of the working well main body is arranged on the side wall of the working well main body close to the edge of the manhole; a grounding box which is connected with a cable protection layer and the ground is arranged on the other side, which is opposite to the manhole, of the working well main body; a cable bracket for accommodating a cable is arranged on the side wall of the working well main body above the grounding box. The cable channel working well has the advantages of simple structure, convenience for running personnel to patrol and overhaul, and capability of improving the running stability of the cable.
Description
Technical field
The utility model relates to a kind of active well, specifically a kind of conduit line active well.
Background technology
Power cable, as one of cable product in power system, is applied in power transmission and transformation line and is mainly used in transmitting and distribution high-power power.Power cable is generally embedded in soil or is laid in raceway groove, tunnel, have between line insulation distance little, without shaft tower, take up an area the advantages such as few, in the economic construction of China, play an important role, therefore ensure that the normal work of cable also becomes the important process of power department.
Conduit line active well is mainly used in placing cable connector, and conduit line active well is taked the design of backfill fine sand more at present, and this conduit line active well exists following shortcoming: 1) conduit line active well backfill fine sand, is unfavorable for the tour maintenance of operation department; 2) cable connector place damages, and is inconvenient to change joint; 3) cable protective layer protector action frequency, observational record difficulty; 4) cable connector place heat is difficult for conduction, easily causes that cable connector place damages.
Utility model content
The utility model technical issues that need to address are to provide the conduit line active well that a kind of security performance is high, facilitate operations staff to overhaul.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is:
A kind of conduit line active well, comprises active well main body and leads to the manhole of active well main body, described manhole is positioned at a side of active well main body, closes in the active well main body wall at manhole edge the vertical cat ladder leading in active well main body is set; In described active well main body, be provided with the grounding box on stube cable overcoat and ground with respect to another sidewall of manhole, in the active well main body wall of grounding box top, be provided with the cable bearer of placing cable.
Further improvement of the utility model is: the stationary fixture that is provided for limiting cable axial forces on described cable bearer.
Further improvement of the utility model is: the through hole that passes in and out cable in described active well main body wall is provided with organic fire prevention plugged zone.
Owing to having adopted technique scheme, the technological progress that the utility model is obtained is:
The utility model provide a kind of simple in structure, facilitate servant to make an inspection tour the conduit line active well of maintenance, can improve the stability of cable operation.Described manhole is arranged on the opposite side of the relative cable bearer of active well main body, facilitates maintainer's down-hole operation; Described cable and cable connector are taked the fixing mode of support, and cable connector place heat can be distributed in time, ensure cable normal operation circumstances, facilitate patrolman's observational record cable working condition simultaneously;
On described cable bearer, be provided for limiting the stationary fixture of cable axial forces, reduce the destruction of axial force to cable.
The through hole that passes in and out cable in described active well main body wall is provided with organic fire prevention plugged zone, once breaking out of fire in active well can effectively stop the intensity of a fire to spread along cable trench.
Brief description of the drawings
Fig. 1 is plan structure figure of the present utility model;
Fig. 2 is the A-A sectional structure chart of Fig. 1.
Wherein, 1, cable bearer, 2, cable connector, 3, manhole, 4, cat ladder, 5, grounding box.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further details:
A kind of conduit line active well, its structure as depicted in figs. 1 and 2, comprises active well main body and leads to the manhole 3 of active well main body.
Manhole is positioned at a side of active well main body, closes in the active well main body wall of manhole 3 the vertical cat ladder 4 leading in active well main body is set, and facilitates maintainer to come in and go out.
In active well main body, be provided with cable bearer 1 and grounding box 5.The through hole that passes in and out cable in active well main body wall is provided with organic fire prevention plugged zone, once breaking out of fire can stop the intensity of a fire to spread along cable trench.
Cable bearer 1 is arranged on a side relative with manhole 3 in active well main body, be bolted on the sidewall of active well main body, for carrying cable and cable connector 2, make heat that cable connector 2 places produce easily and ambient air carry out interchange of heat and distribute, be conducive to staff simultaneously and make an inspection tour Cables for Dam Observation working condition, find in time potential safety hazard; On cable bearer 1, stationary fixture is set, and uses five grades of fixed constraints axial forces, avoid axial force that cable is produced and destroyed.
Grounding box 5 is arranged on the below of cable bearer 1, is connected between cable sheath and ground, reduces the probability of cable jacket insulation breakdown.
While using the utility model, cable bearer 1 is fixed on by expansion bolt on a sidewall of active well main body, cable and cable connector 2 are laid on cable bearer 1 and fix with stationary fixture, grounding box 5 is arranged between cable bearer 1 below and ground, and operations staff enters and can cable working condition be observed and be safeguarded from the manhole of active well main body opposite side while making an inspection tour maintenance.
