Description
The application is application number 201410343031.7, applying date 2014.7.18, title " earthing bar buried depth detector "
Divisional application.
Technical field
The present invention relates to a kind of earthing bar buried depth detectors.
Background technique
Transmission line of electricity is the important component of power grid, the shaft tower of transmission line of electricity tens of rice above ground level, and is exposed to spacious
Wild or high mountain is continuous tens of or hundred kilometers, so there are many chance being struck by lightning, once being struck by lightning, often interrupts power transmission,
In order to prevent thunder from attacking conducting wire directly, often takes and set up lightning conducter along the line, and it is grounded, therefore overhead transmission line shaft tower is effective
It is grounded most important to the safe and stable operation of electric system.
Earthing or grounding means includes grounding body and down conductor, and wherein grounding body is used to the thunder and lightning that will be introduced by down conductor
Flow direction the earth is spread, and buried is an important factor for influencing tower grounding effect.But due in the construction process, earth work category
In concealed work, there is phenomenons not in place for engineering technology supervision, then due to various reasons, unit in charge of construction is buried to grounding body
Can not construction in line with the drawings, keep the undesirable phenomenon of earthing bar buried depth more universal, after resulting in construction, a large amount of shaft tower
Ground resistance is exceeded.
Summary of the invention
The purpose of the present invention is to provide a kind of structurally reasonable, easily and fast, intuitively novel grounded row's buried depth is visited for detection
Survey device.
The technical solution of the invention is as follows:
A kind of novel grounded row's buried depth detector, it is characterized in that: including motor-driven metal spiral bar, metal spiral bar
Bottom be connected with crescent detecting head, and the concave surface of crescent detecting head is downward, and setting instruction detection is deep on metal spiral bar
The graduation mark of degree；Motor connect to form motor operating circuit with the first power supply and relay；Metal spiral bar is connect with relay,
The anode of the connection of the cathode of relay and second source, second source is connect with alarm device, the grounding lead of alarm device and earthing bar
Offline connection, when crescent detecting head touches earthing bar, crescent detecting head, metal spiral bar, relay, the second electricity
Source, alarm device, down conductor, earthing bar constitute alarm circuit；Motor is equipped with handle, and it is anti-that motor is equipped with control point motor
The control switch turned.
Structure of the invention is reasonable, lightly, easy to use, intuitive, can more rapidly during the test of earthing bar buried depth
Ground is squeezed on ground, reads reading, improves test accuracy and working efficiency, ensure that line-to-ground quality, improves overhead transmission line
Run later safety and stability.
Detailed description of the invention
Present invention will be further explained below with reference to the attached drawings and examples.
Fig. 1 is the structural schematic diagram of one embodiment of the invention.
Fig. 2 is that the present invention uses simulation drawing.
Fig. 3 is that the present invention uses circuit diagram.
Specific embodiment
A kind of novel grounded row's buried depth detector, including the metal spiral bar 4 that motor 2 drives, the bottom of metal spiral bar
It is connected with crescent detecting head 7(metal material), and the concave surface of crescent detecting head is downward, setting instruction is visited on metal spiral bar
The graduation mark 5 of depth measurement degree；Motor 2 connect to form motor operating circuit with the first power supply 9 and relay 8；Metal spiral bar with after
Electric appliance 8 connects, and the cathode of relay and second source connects, and anode and alarm device (loudspeaker and the lamp) 10 of second source connect
It connecing, alarm device is connect with the down conductor 11 of earthing bar 12, when crescent detecting head touches earthing bar, crescent detection
Head, metal spiral bar, relay, second source, alarm device, down conductor, earthing bar constitute alarm circuit.It is equipped on motor
Handle 1, motor are connected to the control switch 3 for controlling its positive and negative rotation；Motor is equipped with handle, and motor is equipped with control point motor reversal
Control switch.
When work: according to construction drawing, finding out the buried position of earthing bar, in crescent detecting head insertion soil, will be beaten in figure
After opening control switch 3, motor drives screw rod rotation, and motor power is supplied by lithium battery, and holding handle makes crescent detecting head
And connecting rod vertically squeezes into ground under the promotion of screw rod, when detecting head touches buried earthing bar, circuit communication relay,
Alarm device, down conductor, earthing bar and detecting head, forming circuit, alarm device are alarmed (sound, bright light), while in relay
Coil there is electric current to pass through, in relay switch open, disconnect electric motor loop, motor rotation, read scale above reading,
This reading i.e. base shaft tower earthing bar buried depth value thus.
When extraction, control switch 3 makes motor overturning, at this time the connection of breakage alert device and down conductor, in relay
The current vanishes of coil, switch close, and electric motor loop is connected to again, hold handle, slowly pull out under the reversed promotion of screw rod
Tester out, test terminate.
