Description
Technical Field
The utility model relates to a ground box, especially a protection ground box that is used for power cable metal sheath direct ground connection.
background
The grounding box and the grounding busbar have the function of collecting the grounding wires. The three-phase grounding device is specifically divided into a direct grounding box, a protection grounding box, a three-phase cross interconnection grounding box and a three-phase six-wire grounding box.
The grounding box is often installed outdoors, and has the danger of being impacted by foreign matters; if the protective box is hit, the box body of the grounding box may be damaged, or components in the grounding protective box may be displaced, thereby damaging the internal components of the grounding box.
SUMMERY OF THE UTILITY MODEL
In order to solve the technical problem, the utility model provides a protection grounding box for power cable metal sheath direct ground connection.
The technical scheme of the utility model is that: a protective grounding box for direct grounding of a power cable metal sheath, comprising:
The protective grounding box body is provided with buffer grooves at the top ends of four side plates;
The buffer cover comprises a top cover, a square cover plate and an inner fixing plate, the inner fixing plate and the square cover plate are fixedly arranged at the lower end of the top cover in sequence, and the square cover plate is embedded in the buffer groove;
Buffer gear, buffer gear is including fixed station, pressure spring, connecting rod in pairs, and fixed the locating of fixed station in pairs the top of protection grounding box is in pairs the fixed station is connected with pressure spring one end respectively, and is in pairs the pressure spring on the fixed station is the V type, the other end and the connecting rod of pressure spring are connected, the connecting rod with inner fixed plate fixed connection.
Preferably, the top cover is a roof ridge shape.
Preferably, the buffer mechanism is provided in plurality.
Preferably, the connecting rod is T-shaped.
Preferably, shackles are arranged at two ends of the pressure spring, on the fixed table and the connecting rod, fractures are reserved on the pressure spring shackles, and the pressure spring shackles are clamped into the shackles of the fixed table and the connecting rod through the fractures of the shackles to realize connection.
Preferably, the shackle is a metal shackle.
Compared with the prior art, the utility model discloses following beneficial effect has: the utility model provides a pair of a protection ground connection case for power cable metal sheath direct ground connection, when external foreign matter pounces in protection ground connection case, the foreign matter pounces earlier on the overhead guard, overhead guard and interior fixed plate downstream, under the effect of V type pressure spring in pairs, the overhead guard can cushion and move down a period, the cubic cover plate also further imbeds to the dashpot in, form the striking protection to protection ground connection case, the impact has fully been broken down to overhead guard buffer process, avoid ground connection case directly by the striking, destroy the box of protection ground connection case and damage, perhaps destroy incasement part inner structure (the striking probably produces the part and shifts).
Drawings
Fig. 1 is an overall front view of the present invention.
fig. 2 is an overall left side view of the present invention.
Detailed Description
The present invention will be further described with reference to the accompanying drawings and the following detailed description.
As shown in fig. 1 to 2, a protection grounding box for directly grounding a metal sheath of a power cable comprises a protection grounding box body 1, a buffer cover and a buffer mechanism.
Buffer slot 2 has all been seted up on four directions curb plate top of this protection grounding box 1.
This buffer shield includes ridge shape top shield 3, four directions cover plate 4 and internal fixation board 5, and ridge shape top shield 3's lower extreme is fixed to be equipped with four directions cover plate 4 and internal fixation board 5, and four directions cover plate 4 inlays to be located in buffer slot 2. The effect that four directions cover plate were set in the dashpot lies in: the four-direction cover has shielding and protecting functions on the buffer mechanism in the whole buffer cover, on one hand, the appearance is very attractive, and the buffer mechanism is prevented from being stolen; on the other hand, the external severe environment such as rainwater, wind, frost and the like can not corrode the pressure spring of the buffer mechanism, so that rusting and aging are avoided, and the service life is further prolonged.
This buffer gear is including 6, pressure spring 7, the T type connecting rod of fixed station in pairs, and 6 fixed tops of locating protection grounding box 1 of fixed station in pairs, 6 upper ends of fixed station in pairs are connected with 7 one end of pressure spring respectively, and pressure spring 7 on the fixed station in pairs is the V type, and the other end and the T type connecting rod 8 of pressure spring 7 are connected, T type connecting rod 8 and 5 fixed connection of inner fixed plate. Specifically, the method comprises the following steps: both ends of this pressure spring 7 and fixed station 6, all be equipped with metal shackle 9 on the T type connecting rod, the metal shackle 9 of pressure spring leaves the fracture, and it is gone into in the shackle 9 of fixed station, connecting rod through the shackle fracture card, realizes fixed linking to each other.
This buffer gear is a plurality of, and the cushioning effect is better.
The above-mentioned embodiments are only preferred embodiments of the present invention, and the scope of the right of the present invention should not be limited thereby, and therefore, modifications, equivalent changes, improvements, etc. made in the claims of the present invention are still included in the scope of the present invention.
