Abstract
The invention discloses a grounding bar burial depth detector enabling fast and intuitive detection. The grounding bar burial depth detector comprises a metal screw rod driven by a motor; the bottom of the metal screw rod is connected with a crescent-shaped detection head; the concave surface of the crescent-shaped detection head faces downwards; the metal screw rod is provided scale lines indicating detection depth; the motor is connected with a first power source and a relay, so that a motor working circuit can be formed; the metal screw rod is connected with the relay; the relay is connected with the negative pole of a second power source; the positive pole of the second power source is connected with an alarm; the alarm is connected with the grounding downlead of a grounding bar; and when the crescent-shaped detection head contacts with the grounding bar, the crescent-shaped detection head, the metal screw rod, the relay, the second power source, the alarm, the grounding downlead and the grounding bar form an alarm loop. The grounding bar burial depth detector of the invention has the advantages of reasonable structure, light weight and convenient and intuitive use. The grounding bar burial depth detector can be fast driven into the ground in the process of a grounding bar burial depth test, readings can be read, and testing accuracy and work efficiency can be improved.
Description
The application is the divisional application of application number 201410343031.7, applying date 2014.7.18, title " earthing bar buried depth detector ".
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, often make power transmission interrupt, in order to prevent thunder from attacking wire directly, often take to set up lightning conducter along the line, and by it ground connection, therefore the safe and stable operation of effective grounding to electric system of overhead transmission line shaft tower is most important.
Earthing device comprises grounding body and down conductor, and wherein grounding body is used for the lightning current introduced by down conductor to spread to the earth, and it is buried is the key factor affecting tower grounding effect.But due in work progress, earth work belongs to concealed work, engineering supervision also 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, result in after construction terminates, a large amount of pole tower ground resistances exceeds standard.
Summary of the invention
The object of the present invention is to provide a kind of rational in infrastructure, detection easily and fast, novel grounded row's buried depth detector intuitively.
Technical solution of the present invention is:
A kind of novel grounded row's buried depth detector, it 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, metal spiral bar is arranged the scale mark of instruction investigation depth; 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, lightly, easy to use, directly perceived, more promptly can squeeze into ground in the process of earthing bar buried depth test, read reading, improve test accuracy and work efficiency, ensure that line-to-ground quality, improve overhead transmission line and run 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, metal spiral bar is arranged the scale mark 5 of instruction investigation depth; 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.Motor is equipped with handle 1, motor is connected to the gauge tap 3 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, after opening gauge tap 3, driven by motor screw rod rotates, motor power is supplied by lithium battery, holding handle makes crescent detecting head and connecting rod vertically squeeze into ground under the promotion of screw rod, 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 simultaneously in relay has electric current to pass through, relay breaker in middle is opened, 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.
When extracting, gauge tap 3 makes motor overturning, now the connection of breakage alert device and down conductor, 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 terminates.
