The cable protecting device at cable both ends remains unchanged, and installation personnel can be by the both ends of helical member 4 in remaining cable protecting device
It is taken out from the first blind hole and the second blind hole, so that helical member 4 is separated with fixed plate, after reaching new cable position, then again
Fixed new fixed plate, helical member 4 is connect with new fixed plate, repacking can be completed；Therefore compared with the prior art in, in electricity
When cable is rectified and improved, entire cable protecting device all abandons do not have to for, in this programme can recycling and reusing helical member 4, save
Economic cost；Also, when cable is transformed, helical member 4 can be screwed out or be screwed in by this programme, realized and changed spiral on cable
The number of part 4, that is to say, that realize change cable on cable protecting device quantity, it is more flexible to cable run into
Row transformation.
(3) detection when using
Cable at all seasons in, the distance between fixed plate to cable surface certain point be have it is a certain range of, due to
Range finder module is just on helical member, and helical member is fitted with cable surface when in use, that is to say, that fixed plate is to surveying
Away from the distance between module this two o'clock be have it is a certain range of；And if cable cracks, the crack of cracking centainly has distance,
The actual range that range finder module detects will be bigger than distance when not cracking；Therefore, by maximum distance information storage to storage
In device, if it find that actual range information is bigger than maximum distance information, then it may determine that, cable at this time centainly cracks.
According to above-mentioned principle, there is following setting in this programme:
While initially being installed, while paying attention to guaranteeing that range finder module is corresponding with the induction module position of helical member 4,
Then the induction module of First Year is used as to gauged distance at a distance from range finder module, by the normal pitch discrete time corresponding storage
Gauged distance information is used as into memory；To after second year, third year even N, by the induction module in the year and survey
Be used as actual range away from the distance between module, then by the corresponding storage of actual range and time into memory as it is practical away from
From information；Comparator according to the time be index, gauged distance information and actual range information are recalled from memory, to it is current when
Between gauged distance and actual range compare, when find actual range be greater than gauged distance when, comparator to controller send out
It after sending high-frequency signal, controller to receive the high-frequency signal of comparator transmission, sends a warning message to antenna, so that antenna receives
To after the warning information, server outwardly sends alarm signal；
And extraneous server, the alarm signal of each cable protecting device is numbered, due to each cable protection
