Abstract
The utility model provides a kind of blocking device, and blocking device comprises: the first sealing configuration, is arranged in cable boundary room or the passage that is communicated with conduit shaft of outdoor box equipment; Second sealing configuration, is positioned at the below of the first sealing configuration, and the second sealing configuration is arranged on the one end near conduit shaft on passage.By the blocking device that the utility model provides, solve the indoor existence of demarcating of cable in prior art and amass water problem.
Description
Technical field
The utility model relates to electric cable transporting field, in particular to a kind of blocking device.
Background technique
At present, cable boundary room or outdoor box equipment and conduit shaft, underground electric channel connection, because conduit shaft humidity is larger, cable boundary room and conduit shaft are by means of only covering palte seal, cable boundary indoor are made to occur that water vapour condenses and produces ponding, cable boundary room easily causes electrical part malfunctioning or be short-circuited under dampness, and then causes power outage, affects the normal use of electric power.
Model utility content
Main purpose of the present utility model is to provide a kind of blocking device, amasss water problem to solve the indoor existence of demarcating of cable in prior art.
To achieve these goals, according to a kind of blocking device that the utility model provides, blocking device comprises: the first sealing configuration, is arranged in cable boundary room or the passage that is communicated with conduit shaft of outdoor box equipment; Second sealing configuration, is positioned at the below of the first sealing configuration, and the second sealing configuration is arranged on the one end near conduit shaft on passage.
Further, the first sealing configuration is needle punched blanket.
Further, needle punched blanket is alumina silicate needle punched blanket.
Further, the second sealing configuration is shutoff cover plate.
Further, shutoff cover plate is made up of stainless steel.
Further, the inwall of passage is provided with the first watertightness barrier.
Further, blocking device also comprises Stamping Steel Ribbon, and Stamping Steel Ribbon is arranged between shutoff cover plate and the inwall of passage.
Application the technical solution of the utility model, by providing a kind of blocking device, and this blocking device is arranged in passage that the cable boundary passage that is communicated with conduit shaft of room or outdoor box equipment is communicated with conduit shaft, effectively can reduce the humidity that cable boundary is indoor, particularly, in the passage be communicated with conduit shaft by the room that demarcates at cable, the first sealing configuration and the second sealing configuration are set, to carry out shutoff by multi-layer sealing structure to passage, thus the humid air avoided in conduit shaft enters in cable boundary room by passage, ensure the normal operation of cable boundary room.
Accompanying drawing explanation
The Figure of description forming a application's part is used to provide further understanding of the present utility model, and schematic description and description of the present utility model, for explaining the utility model, is not formed improper restriction of the present utility model.In the accompanying drawings:
Fig. 1 shows the structural representation of the blocking device that the utility model provides.
Wherein, above-mentioned accompanying drawing comprises the following drawings mark:
10, cable boundary room; 20, conduit shaft; 31, the first sealing configuration; 32, the second sealing configuration.
Embodiment
It should be noted that, when not conflicting, the embodiment in the application and the feature in embodiment can combine mutually.Below with reference to the accompanying drawings and describe the utility model in detail in conjunction with the embodiments.
As shown in Figure 1, the utility model embodiment provides a kind of blocking device, wherein, this blocking device comprises the first sealing configuration 31 and the second sealing configuration 32, first sealing configuration 31 is arranged in cable boundary room 10 or the passage that is communicated with conduit shaft 20 of outdoor box equipment, second sealing configuration 32 is positioned at the below of the first sealing configuration 31, and the second sealing configuration 32 is arranged on the one end near conduit shaft 20 on passage.
By the blocking device that the utility model provides, and this blocking device is arranged in passage that the cable boundary passage that is communicated with conduit shaft of room 10 or outdoor box equipment is communicated with conduit shaft, effectively can reduce the humidity in cable boundary room 10, particularly, in the passage be communicated with conduit shaft 20 by the room 10 that demarcates at cable, the first sealing configuration 31 and the second sealing configuration 32 is set, to carry out shutoff by multi-layer sealing structure to passage, thus the humid air avoided in conduit shaft 20 enters in cable boundary room 10 by passage, ensure the normal operation of cable boundary room 10.
In the specific embodiment that the utility model provides, first sealing configuration 31 is set to needle punched blanket, needle punched blanket is arranged in passage, can prevents the wet gas in conduit shaft 20 from passage, entering cable boundary room 10, and then the humidity in cable boundary room 10 can be reduced.From those skilled in the art, in order to provide better sealing characteristics, multilayer needle punched blanket can be set.In order to improve the practicability of needle punched blanket, needle punched blanket is made up of alumina silicate needle punched blanket material, and it has fire prevention, waterproof, the characteristic such as heat insulation.It should be noted that: the material of needle punched blanket can be not limited to the material that the present embodiment provides, as long as can play waterproof action.
In the specific embodiment that the utility model provides, the second sealing configuration 32 is set to shutoff cover plate, and shutoff cover plate is sealed on passage bottom, to realize the effect of sealing channel.In order to avoid shutoff cover plate gets rusty, rots and make seal failure, as preferably, shutoff cover plate is made up of 304 stainless steels.It should be noted that: the material of shutoff cover plate can be not limited to the material that the present embodiment provides, as long as can play waterproof action.In addition, in order to sealing channel better, Stamping Steel Ribbon can be set at shutoff cover plate and expanding channels place, improve sealability.Stamping Steel Ribbon can adopt ethylene propylene diene rubber, and it has good high temperature resistant, corrosion-resistant and oxidation resistance.
Wherein, in order to reach better waterproofing effect, avoiding infiltrating cable boundary room 10 by vias inner walls, the inwall of passage arranges the first watertightness barrier.So better can improve waterproof and the humidity resistance of this blocking device.As preferred embodiment, the second watertightness barrier can be set on the well cavity wall of conduit shaft 20, thus can from conduit shaft 20 control well humidity.Particularly, waterproof paint can being coated with in vias inner walls and well cavity wall, in order to ensure its water-proof performance, rain rainbow board waterproof paint can being adopted to brush.
By the blocking device that the utility model provides, large, the easy generation of boundary indoor humidity can be solved well and amass water problem, thus the problem of consequent equipment short circuit can be avoided, ensure that the normal operation of electrical network.
The foregoing is only preferred embodiment of the present utility model, be not limited to the utility model, for a person skilled in the art, the utility model can have various modifications and variations.All within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
