Specific implementation mode
The technical solution of the utility model embodiment is explained with reference to the attached drawing of the utility model embodiment and
Illustrate, but following embodiments are only the preferred embodiment of the utility model, and not all.Based on the implementation example in the implementation mode,
Those skilled in the art's obtained other embodiment without making creative work, belongs to the utility model
Protection domain.
The failure of cable can be mainly divided into following three kinds of forms according to property：
(1) insulation fault：There is the reason of this failure and be because the dielectric level of cable is low cause to occur leaky,
Between master core or core wire insulation against ground resistance do not reach requirement and core between or earth leakage current it is excessive.
(2) earth fault：Earth fault is mainly divided into dead ground, low resistance earthing and high resistance according to insulating resistance value
It is grounded three kinds of situations.It is zero that dead ground, which refers to the insulating resistance value between core wire and the earth,；Insulated electro between local core and the earth
Referred to as low resistance earthing when resistance value is less than 500 kilo-ohms；When the insulation resistance between core and the earth be more than 500 kilo-ohms, Huo Zheda
To 1000 kilo-ohms referred above to high resistance grounding.
(3) disconnection fault：When one phase of cable or two-phase core wire disconnect, disconnection fault occurs.
For above-mentioned cable fault reason, a kind of flexible trunk mechanical arm of the utility model design is applied in telescopic formula well
Road is visited on mirror, and cable work well fault-finding is used for.
Flexible trunk mechanical arm is a kind of bio-robot of the movement mechanism of novel imitation trunk organ, because it can be
Any part generates plastic deformation, has very strong avoidance ability and environment-adapting ability, is used widely in recent years.For electricity
Power cable well narrow space, bad environments, equipment is complicated, often needs the factors such as live line work, is brought to electric power overhaul worker's operation
Some potential safety problems, thus using flexible trunk mechanical arm as front end detection device instead of artificial downhole detection operation.
Telescopic formula hoistway as shown in Figure 1 visits mirror, including electric telescopic rod 3, flexible trunk mechanical arm 1, remote control
Device and terminal display device, wherein the electric telescopic rod is stretched for the cable work well of different depth to adjust length
Degree, the rear end of the flexibility trunk mechanical arm and the front end of electric telescopic rod connect, and the front end of the flexibility trunk mechanical arm is set
There are front end detection device 2, the flexibility trunk mechanical arm to stretch into cable work well, flexible become is generated by controlling motor control
Shape acquires down-hole information by front end detection device and is transferred to terminal display device and shows, the remote control device is used for
Remote control electric telescopic rod and flexible trunk mechanical arm action.
Refering to what is shown in Fig. 2, the flexibility trunk mechanical arm 1 includes the root long drawing in multistage joint and multistage joint of connecting
Spring 12 and more wires 14, the joint include the support disc 11 at both ends, and the center of the support disc is offered for length
The tension spring through-hole that tension spring passes through is equipped with the short compression spring 13 being sleeved on outside outside long tension spring, the support plate between both ends support disc
The edge of piece it is uniformly distributed there are three for three wires correspond to across metal string holes.
In the present embodiment, the support disc is equilateral triangle, and tension spring through-hole is arranged in the geometry of support disc
At the heart, three metal string holes are distributed on three edges of support disc.The center ring of the support disc is set around tension spring through-hole
It is useful for fixing the sleeve 111 of short compression spring end.
Long tension spring makes device have certain impact resistance and self- recoverage power, and it is short compression spring to be sleeved on outside tension spring, makes machinery
Arm has higher bending softness.Three wires tightness are for controlling trunk manipulator motion direction, three metals
The tightness of line is controlled by corresponding three 12V DC slowspeed machines.When control, some motor is rotated forward will by metal wire
Center tension spring stretches, and in addition two motor reversals suitably loosen, and makes to move to the direction at the top of trunk or certain two wires control
System stretches, another motor reversal suitably loosens, can also be three motors while tightening, and realizes trunk mechanical arm in space
Three-dimensional whipping.Motor reversal can make mechanical arm restore initial position.
Three control motors are mounted in motor mounting box 4, and motor mounting box may be mounted at flexible trunk mechanical arm
Rear end, or it is installed along with electric telescopic rod motor the rear end of electric telescopic rod.
