Specific embodiment

The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work Every other embodiment obtained, fall within the protection scope of the utility model.

Fig. 1-5 is please referred to, the utility model provides a kind of technical solution: a kind of bus duct with multi-stage protection function, Including storage tank 1, parcel shelf 2, earth leakage protective component 3, electric conductor 4, fire resistant coating 5, fixture block 6, insulation board 7, protective shell 8, slide Pole 9, sliding slot 10, spring 11, hole 12, fixed plate 13, knob 14, bungee 15, fixed link 16, confinement block 17, first connect Block 18, the second link block 19 and chain 20, the inside of storage tank 1 are equipped with parcel shelf 2, and top one end setting of parcel shelf 2 There is earth leakage protective component 3, while the top other end of parcel shelf 2 is equipped with electric conductor 4, the bottom of electric conductor 4 passes through insulation board 7 It is connected with each other with parcel shelf 2, and the avris of parcel shelf 2 is connected with each other by fixture block 6 and storage tank 1, while the surface of parcel shelf 2 It is covered with fire resistant coating 5, the avris of storage tank 1 is provided with protective shell 8, and the avris of storage tank 1 offers sliding slot 10, protective shell 8 are connected with each other by litter 9 and storage tank 1, and the avris of litter 9 is provided with spring 11, while the end point of protective shell 8 is reserved Hole 12, the middle position of storage tank 1 is fixed with fixed plate 13, and the middle position of fixed plate 13 is equipped with knob 14, together When knob 14 avris fixed link 16 is connected with by bungee 15, and the middle position of fixed link 16 is connected with confinement block 17, the bottom of protective shell 8 is fixed with one end of the first link block 18, and the other end of the first link block 18 passes through chain 20 and the Two link blocks 19 are connected with each other；

Parcel shelf 2 and storage tank 1 constitute lifting mounting structure, and the avris of parcel shelf 2 is to be connected together with storage tank 1, Protective shell 8 is provided with 2 about the axisymmetrical of storage tank 1, and protective shell 8 and storage tank 1 constitute the structure that is slidably installed, rotation After knob 14, knob 14 indirectly stretches out fixed link 16, is detached from from the end point of protective shell 8, and spring 11 will be protected at this time Shell 8 is outwardly against protective shell 8 can be pulled up parcel shelf 2 by chain 20 at this time, be reduced with this to 2 top of parcel shelf The difficulty of component maintenance；

The upper surface of fixed plate 13 and the end point of protective shell 8 are bonded to each other, and fixed plate 13 is integrated with storage tank 1 Setting, while axisymmetrical of the fixed plate 13 about storage tank 1 are bonded to each other and leak are avoided to enter storage by the junction of the two The inside of object case 1 damages the component inside storage tank 1, and axisymmetrical setting ensure that consolidating for 13 top of fixed plate Protective shell 8 arranged symmetrically can be fixed simultaneously for fixed pole 16；

Fixed link 16 and confinement block 17 constitute flexible mounting structure, and fixed link 16 is connected together with confinement block 17, Gu Fixed pole 16 and the end point of protective shell 8 are mutually perpendicular to, and fixed link 16 runs through the end point that protective shell 8 is arranged in, and are shed to solid After the pulling force of fixed pole 16, the power that bungee 15 is sprung back is able to drive the reset of fixed link 16, is limited by confinement block 17, guarantees Fixed link 16 is merely able to move horizontally, will not run-off the straight the case where, and can guarantee fixed link 16 always with protective shell 8 End point it is vertical.

Working principle: when using the bus duct with multi-stage protection function, according to Fig. 1-5, when the device needs When overhauling, bungee 15 is wound and collects by turning knob 14, knob 14, and fixed link 16 is pulled out, fixed Bar 16 is then detached from from the end point of protective shell 8 when pulled in the internal slide of confinement block 17, and protective shell 8 is not by solid at this time Protective shell 8 can be pushed out by litter 9, be completed with this by the active force that fixed pole 16 limits, the active force that spring 11 is sprung back The opening of protective shell 8 during protective shell 8 slides in and out, is connected due to passing through chain 20 between protective shell 8 and parcel shelf 2, And the active force that the avris of parcel shelf 2 is restricted, therefore when protective shell 8 slides, 2 under tension of parcel shelf is to moving up It is dynamic, reduce the difficulty of the component maintenance inside storage tank 1；

According to Fig. 1-3, when protective shell 8 is covered on the outside of storage tank 1, therefore when leak occurs in the external world, protection Shell 8 can play the role of barrier, and the inside for avoiding water from entering storage tank 1 damages component, and when storage tank 1 When inside appearance electric leakage is caught fire, fire resistant coating 5 can completely cut off air fire extinguishing and intensity of a fire continuous enlargement is avoided to damage component, Earth leakage protective component 3 can play the role of powering off electric leakage.

Finally it should be noted that the above content is only to illustrate the technical solution of the utility model, rather than it is practical to this The limitation of novel protected range, those skilled in the art to the technical solution of the utility model carry out it is simple modification or Person's equivalent replacement, all without departing from the spirit and scope of technical solutions of the utility model.
