Ground description, it is clear that described embodiment is only a part of the embodiments of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, those of ordinary skill in the art without making creative work it is obtained it is all its
Its embodiment, shall fall within the protection scope of the present invention.
Here, it should also be noted that, in order to avoid having obscured the present invention because of unnecessary details, in the accompanying drawings only
Show with closely related structure and/or processing step according to the solution of the present invention, and be omitted little with relationship of the present invention
Other details.
As shown in Figure 1, being that the present invention provides stackable cable intermediate joint protecting crust overall structure diagram；It ties together
It closes shown in Fig. 2 to Fig. 5.
In embodiments of the present invention, the stackable cable intermediate joint protecting crust comprising pedestal 1, upper cover 2 and
Stack pedestal 3；Wherein：
The pedestal 1 and upper cover 2 are semi-surrounding structure, and the opening of the pedestal 1 and the upper cover 2 is oppositely arranged, the bottom
Seat 1 and the upper cover 2 are formed by accommodation space, place for two high-voltage cable middle joints 4 side by side；
The pedestal 1 is respectively formed with first pair of extension bar 10 and second pair of extension bar 11, direction and cable intermediate joint at both ends
The long side of protecting crust is vertical, and the two is parallel to each other；It is respectively formed in first pair of extension bar 10 and second pair of 11 both ends of extension bar
Abutment shaft and butt hole are specifically respectively formed the first abutment shaft 100 and the first butt hole 101 at first pair of 10 both ends of extension bar,
The second abutment shaft 110 and the second butt hole 110 are respectively formed at second pair of 11 both ends of extension bar；The cable intermediate joint of adjacent one another
Cooperated between protecting crust by abutment shaft and butt hole；
Specifically, in fig. 1 it is shown that two cable intermediate joint protecting crusts, below a protecting crust the first abutment shaft 100
Be plugged in the first butt hole 101 of a protecting crust above, under the second abutment shaft 200 of once protecting crust be plugged on above one
In second butt hole 111 of a protecting crust, to make two protecting crusts formation, one combination up and down；In some instances, it docks
Between axis and butt hole with being combined into clearance fit, for example, the outer diameter of abutment shaft will be with for 25.0mm, and the internal diameter of butt hole is
25.2mm, the two fit system are loose fit.
The third abutment shaft 300 for stacking pedestal 2 and including bottom plate and being set on bottom plate, third abutment shaft 300
Quantity be two, for respectively be located at lower side first pair of extension bar 10 and second pair of extension bar 11 on butt hole
（101,110）It matches；And bottom plate has wider contact surface, and the protecting crust stacked can be made to place vertically.
More specifically, be fixed in upper cover 2 and the longitudinally middle position of pedestal 1 by multiple bolts 7, make protecting crust with
Cable body forms a closed space, can prevent electric arc and fragment from flying out.
Wherein, first pair of extension bar, 10, second pairs of extension bars 11 and the pedestal 1 are integrally formed.
In addition, the both ends of the upper cover 2 and pedestal 1 are respectively formed with the electricity for 4 end of the high-voltage cable middle joint
The through-hole that cable 5 passes through.In one example, the cable 5 is 110kV cable, and outer diameter is diameter 87mm, the cable mid head
4 outer diameter is 150mm.
