Description
Technical field
A kind of protection device preventing power transmission line overhead ground wire from coming off, belongs to transmission line of electricity and connects equipment technical field.
Background technology
According to State Grid Corporation of China's anti-accident technical measures requirement, for keeping away at the important leap of ultra-high-tension power transmission line aerial line
Exempting from wire dropping all uses double extension to protect, but extension the most double to ground wire is not distinctly claimed.But existing ground wire list is hanging
Suspension arrangement, easily produces corrosion, bolt looseness disengaging, ground wire may be caused to come off, thus cause great due to life-time service
Accident, has a strong impact on the safe operation of circuit.
Utility model content
Technical problem to be solved in the utility model be to provide one can work as ground wire suspension arrangement damage time, Neng Goufang
The protection device that only ground wire comes off.
For solving above-mentioned technical problem, the technical scheme that this utility model is used: one prevents the built on stilts ground of transmission line of electricity
The protection device that line comes off, including the first protection board and second protection board of relative thirty years of age, described first protection board, the second guarantor
Backplate two ends all have bolt hole, and described first protection board top, the second protection board top are by the first bolt connection, institute
State the first protection board bottom, the second protection board bottom to be connected by the second bolt；
Described first protection board, the second protection board are " several " character form structure.
The split pin preventing bolt falling it is equipped with in described first bolt, the end of the second bolt.
Compared to the prior art this utility model has the beneficial effect that this utility model is outside original suspension clamp
Side, increases interconnective first protection board and the second protection board, it is achieved that ground wire suspension clamp because of a variety of causes come off time, right
Aerial earth wire hitch point is effectively protected, and ground wire can be avoided to come off and cause transmission line of electricity tripping operation and other accident.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structural representation of the first protection board.
Fig. 3 is the side view of Fig. 2.
Fig. 4 is working state schematic representation of the present utility model.
In figure, 1 is the first protection board, and 2 is the second protection board, and 3 is the first bolt, and 4 is the second bolt.
Detailed description of the invention
As Figure 1-Figure 4, a kind of protection device preventing power transmission line overhead ground wire from coming off, including relative thirty years of age
One protection board 1 and the second protection board 2, all has bolt hole at described first protection board the 1, second protection board 2 two ends, and described
First protection board 1 top, the second protection board 2 top are connected by the first bolt 3, described first protection board 1 bottom, the second protection
Plate 2 bottom is connected by the second bolt 4；
Described first protection board the 1, second protection board 2 is " several " character form structure.
The split pin preventing bolt falling it is equipped with in the end of described first bolt the 3, second bolt 4.
Above-described embodiment is the explanation to this utility model structure and unrestricted, without departing from this utility model principle premise
Lower made deformation is also within protection domain of the present utility model.
