Abstract
The invention discloses a novel grounding bar burial depth detector which comprises a metal screw rod driven by a motor. The bottom of the metal screw rod is connected with a crescent detection head, and the concave surface of the crescent detection head faces downwards. The metal screw rod is provided with scale lines for indicating detection depth. The motor is connected with a first power supply and a relay to form a motor operating circuit. The metal screw rod is connected with the relay. The relay is connected with the negative electrode of a second power supply. The positive electrode of the second power supply is connected with an alarm. The alarm is connected with a grounding down lead of a grounding bar. When the crescent detection head makes contact with the grounding bar, the crescent detection head, the metal screw rod, the relay, the second power supply, the alarm, the grounding down lead and the grounding bar form an alarm loop. The novel grounding bar burial depth detector is reasonable in structure, light and convenient and visual to use; in the process of testing the burial depth of the grounding bar, the detector can be driven into the ground more rapidly to read the depth value, and therefore testing accuracy and work efficiency are improved.
Description
Technical field
The present invention relates to a kind of earthing bar buried depth detector.
Background technology
Transmission line of electricity is the important component part of electrical network, shaft tower tens of rice above ground level of transmission line of electricity, and be exposed to wilderness or high mountain, be continuous tens of or hundred kilometers, so the chance of being struck by lightning is a lot, once be struck by lightning, tend to make power transmission to interrupt, in order to prevent thunder direct attack wire, often take to set up lightning conducter along the line, and by it ground connection, so the effective grounding of overhead transmission line shaft tower is most important to the safe and stable operation of electric system.
Earthing device comprises grounding body and down conductor, and wherein grounding body is used for the lightning current of being introduced by down conductor to spread to the earth, and it is buried is the key factor that affects tower grounding effect.But due in work progress, earth work belongs to concealed work, engineering supervision exists phenomenon not in place, again due to a variety of causes, unit in charge of construction to grounding body is buried can not construction in line with the drawings, make the undesirable phenomenon of earthing bar buried depth comparatively general, after having caused construction to finish, a large amount of pole tower ground resistances exceed standard.
Summary of the invention
The object of the present invention is to provide a kind of rational in infrastructurely, survey easily and fast, novel grounded row's buried depth detector intuitively.
Technical solution of the present invention is:
Novel grounded row's buried depth detector, is characterized in that: comprise motor-driven metal spiral bar, the bottom of metal spiral bar is connected with crescent detecting head, and the concave surface of crescent detecting head is downward, and the scale mark of indication investigation depth is set on metal spiral bar; Motor and the first power supply and relay are connected to form machine operation circuit; Metal spiral bar is connected with relay, relay is connected with the negative pole of second source, the positive pole of second source is connected with warning horn, warning horn is connected with the down conductor of earthing bar, when crescent detecting head touches earthing bar, crescent detecting head, metal spiral bar, relay, second source, warning horn, down conductor, earthing bar form alarm circuit; Motor is provided with handle, and motor is provided with the gauge tap of reference mark motor reversal.
The present invention is rational in infrastructure, light and handy, easy to use, directly perceived, in the process of earthing bar buried depth test, can more promptly squeeze into ground, read reading, improve test accuracy and work efficiency, guaranteed line-to-ground quality, improved overhead transmission line and move later safety and stability.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the invention will be further described.
Fig. 1 is the structural representation 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.
Embodiment
A kind of novel grounded row's buried depth detector, comprise the metal spiral bar 4 that motor 2 drives, the bottom of metal spiral bar is connected with crescent detecting head 7(metal material), and the concave surface of crescent detecting head is downward, and the scale mark 5 of indication investigation depth is set on metal spiral bar; Motor 2 and the first power supply 9 and relay 8 are connected to form machine operation circuit; Metal spiral bar is connected with relay 8, relay is connected with the negative pole of second source, the positive pole of second source is connected with warning horn (loudspeaker and lamp) 10, warning horn is connected with the down conductor 11 of earthing bar 12, when crescent detecting head touches earthing bar, crescent detecting head, metal spiral bar, relay, second source, warning horn, down conductor, earthing bar form alarm circuit.Handle 1 is housed on motor, and motor is connected to the gauge tap 3 of controlling its rotating; Motor is provided with handle, and motor is provided with the gauge tap of reference mark motor reversal.
During work: according to construction drawing, find out position that earthing bar buries, crescent detecting head in figure is inserted in soil, open after gauge tap 3, driven by motor screw rod rotates, motor power is supplied with by lithium battery, holding handle makes crescent detecting head and connecting rod under the promotion of screw rod, vertically squeeze into ground, when detecting head touches buried earthing bar, circuit communication relay, warning horn, down conductor, earthing bar and detecting head, form loop, warning horn warning (sound, bright light), coil in relay has electric current to pass through simultaneously, switch opens in relay, electric motor loop is disconnected, electric machine rotation, read the reading above scale, this reading i.e. base tower grounding row buried depth value for this reason.
While extracting, gauge tap 3 makes motor overturning, and now breakage alert device and down conductor is connected, the current vanishes of relay coil, switch closes, and electric motor loop is communicated with again, hold handle, under the reverse promotion of screw rod, slowly extract tester, test finishes.
