Abstract
The utility model discloses a kind of adjustable pipeline plugging system, include strip air bag, described strip air bag includes Double-layer bag structure, the week of Double-layer bag structure is along being connected to form one, and the internal cavities of Double-layer bag structure is separate, be respectively arranged with self tap-hole type charging connector.The utility model adopts double-layer inflatable bag structure, and structure is simple, convenient to operation, single inflatable bag body or two inflatable bag body can be used, to adapt to the instructions for use of different tube diameters, good sealing effect according to the size of cable duct caliber, cost is low, has good popularizing value.
Description
Technical field
The utility model relates to a kind of duct closing type device, belongs to technical field of power systems, refers in particular to a kind of adjustable pipeline plugging system.
Background technology
Along with developing rapidly of China's electric power and communication career, the laying of underground cable is more and more universal.Subway is generally all emitted in the underground groove that digs in advance, and arranges wellhole at a certain distance, as the work of wiring, examination and maintenance etc.Because these cable ducts are arranged in underground groove for a long time, rainwater, sewage, mud or worm mouse etc. all can enter in cable duct, not only can destroy cable, and can cause the blocking of cable duct.Therefore, in order to avoid the appearance of the problems referred to above, current common practices adopts cement or other fire-proof mud to seal up at the port of cable duct, although this way can prevent foreign object from entering cable duct, but also there is following shortcoming, such as, after grout off lives cable duct port, make dilatation in the future very difficult, need to expend larger labour and destroy these cement structures, take time and effort, and easily damaging original cable, cost is also higher simultaneously, is difficult to bear for general construction unit.
Utility model content
The purpose of this utility model is to overcome shortcoming of the prior art with not enough, and provide a kind of adjustable pipeline plugging system, this plugging device structure is simple, easy to operate, and can regulate the use adapting to different tube diameters, good sealing effect, cost is low.
To achieve these goals, the utility model realizes according to following technical scheme:
A kind of adjustable pipeline plugging system, include strip air bag, described strip air bag includes Double-layer bag structure, and the week of Double-layer bag structure is along being connected to form one, and the internal cavities of Double-layer bag structure is separate, be respectively arranged with self tap-hole type charging connector.
Further, described strip air bag includes the first inflatable bag body and the second inflatable bag body, and the first inflatable bag body and the second inflatable bag body share a middle double wall.
Further, the two sides of described strip air bag are respectively arranged with sealing joint strip along its length.
Further, described self tap-hole type charging connector is equipped with a dismounting formula inflation tubule.
Further, described strip air bag adopts expansion silica gel sandwiched Flexible wire one-body molded.
Compared with prior art, its beneficial effect is the utility model:
The utility model adopts double-layer inflatable bag structure, and structure is simple, convenient to operation, single inflatable bag body or two inflatable bag body can be used, to adapt to the instructions for use of different tube diameters, good sealing effect according to the size of cable duct caliber, cost is low, has good popularizing value.
In order to the utility model can be understood more clearly, illustrate below with reference to accompanying drawing and set forth embodiment of the present utility model.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is partial structurtes cutaway view of the present utility model.
Embodiment
As shown in Figure 1, 2, adjustable pipeline plugging system described in the utility model, include strip air bag, described strip air bag includes the first inflatable bag body 1 and the second inflatable bag body 2, first inflatable bag body 1 and the second inflatable bag body 2 share a middle double wall, and the week of two inflatable bag bodies is along being connected to form one.
The outside of above-mentioned first inflatable bag body 1 and the second inflatable bag body 2 is respectively arranged with sealing joint strip 11,21 and self tap-hole type charging connector along its length, and wherein, self tap-hole type charging connector is equipped with a dismounting formula inflation tubule 12,22.
Above-mentioned first inflatable bag body 1 and the second inflatable bag body 2 adopt expansion silica gel sandwiched Flexible wire one-body molded, and inflation can be expanded, and has stronger resistance to compression corrosion resistance.
Use principle of the present utility model is as described below: when needs shutoff cable duct, strip air bag be wrapped in cable outside and be placed in cable duct port, then by dismounting formula inflation tubule, inflatable bag body is inflated, single inflatable bag body or two inflatable bag bodies can be selected according to pipe diameter size, when being inflated to suitable air pressure, inflatable bag body expansion plugging lives the remaining space of cable duct, the sealing joint strip of inflatable bag body and cable duct wall close contact, then dismounting formula inflation tubule is firmly pulled out, due to charging connector can be lived by self-plugging after the expansion silica gel expansion of inflatable bag body, therefore ensure to leak gas, whole operating process is easily convenient, save time quick.
The utility model is not limited to above-mentioned execution mode, if do not depart from spirit and scope of the present utility model to various change of the present utility model or modification, if these are changed and modification belongs within claim of the present utility model and equivalent technologies scope, then the utility model is also intended to comprise these change and modification.
