Abstract
Multiple vibrating wire sensors are embedded in the field civil engineering safety monitoring, and the sensors are connected with a measuring device via a long cable. The cable is easy to attack by inductive thunder, and the sensor damage is unavoidable, at present, a signal lightning arrester which is moisture-proof and can be embedded into the earth is unavailable. A BSLA-1500W embedded signal lightning arrester is made of cast aluminium, and lightning protection devices are arranged in an aluminium metallic box. After the sensor cable and a signal cable are arranged in the box, the box is filled with industrial paraffin, a cover plate is sealed, and cable inlet and outlet lines on the two ends are sealed, so a lightning protection part can be arranged in moist soil or water without influencing the sensor measurement, and the sensor is effectively protected.
Description
Technical field
The present invention relates to open-air lightening proof of light current field.
Background technology
In the open air in the civil engineering, for monitoring engineering safety, buried a large amount of transducers underground, these transducers are connected to measuring equipment by very long cable, these cables are especially easily responded to the invasion and attack of thunder, thereby cause the damage of transducer, and these transducers deeply are buried in the earth or are cast in the concrete, as damaging non-exchange, cause the system data disappearance.Present signal lightning arrester does not all have good waterproof, protection against the tide and resistance to compression measure, can not be installed in open-air place without any protection, therefore can not carry out the aperture protection to burying people's formula instrument.
The present invention is fully studying in the situation of present signal lightning arrester and environment for use; the lightning protection device is installed in the aluminum can; after to be installed; industrial paraffin will be poured in the box; seal cover board and the two end cables line of coming in and going out has guaranteed that lightning protection device can place moist earth, water and not affect measurement to transducer.
Summary of the invention
The present invention is the hermetic lightning protection box of development one cover, can protect thunder and lightning, does not affect again the measurement to transducer.The a complete set of accessory that forms comprises: 1 cast aluminium base box (1), 1 cast aluminium cover plate (2), 1 seal washer (3), 4 M4 stainless steel screws (4), 2 M3 stainless steel screws (5), 1 M6 stainless steel screw (6), 2 M16 plastic cable seal nipples (7), 1 lightning protection circuit plate (8).
Operation instruction is as follows:
Be applicable to the various transducers that are buried in the earth or are embedded in the concrete in the open-air project security monitoring.Place, aperture, ground at transducer, sensor cable and signal cable are connect end from the cable of this lightning arrester respectively to be penetrated in the box, function according to the cable internal core wire, one group in twos of difference, correspondence accesses to binding post 1,2 or 4,5 holes of lightning arrester internal lighting protection plate, 3 holes connect cable screening wire, after screwing two ends binding post screw, should be open circuit with universal instrument resistance grade measurement 1,2,4,5 terminals screws and 3 terminals screws, 1 and 1 of two ends binding post, 2 and 2,4 and 4,5 and 5 should be path.After measuring correctly, screw cast aluminium base two ends cable connector, the hermetically-sealed cable inlet port.Pour in the box after again paraffin being melted, after paraffin solidifies, cover the cast aluminium cover plate, screw 4 M4 stainless steel screws.Earth lead is accessed on the M6 stainless steel screw in the lightning arrester base upper right corner or the lower left corner and screw, lightning arrester is buried in the soil of people's transducer aperture get final product.

Embodiment
The present invention is the hermetic lightning protection box of development one cover, can protect thunder and lightning, does not affect again the measurement to transducer.The a complete set of accessory that forms comprises: 1 cast aluminium base box (1), 1 cast aluminium cover plate (2), 1 seal washer (3), 4 M4 stainless steel screws (4), 2 M3 stainless steel screws (5), 1 M6 stainless steel screw (6), 2 M16 plastic cable seal nipples (7), 1 lightning protection circuit plate (8).
Above-mentioned base box and cover plate are aluminium, adopt die casting to form.Cover plate and base contact-making surface mill flat with milling cutter, there are Φ 4.5 installing holes at 4 angles of cover plate.The interior process of base cavity milling cutter mills flat, and two ends centre drill M16 internal thread hole connects inner, the M3 internal thread hole of the dark 8mm of processing on the inner chamber platform, and 4 angles of end face process the M4 internal thread hole of dark 10mm, and the hole of the outside upper left corner of base and bottom right angular bit Φ 7 is run through.Sealing ring is that the mould pressure injection forms, and all screws are stainless steel material.
Two M16 plastic cable seal nipples are screwed in base box two stomidiums, and it is inner that circuit board is installed on the base box, the ground terminal on the circuit board accessed on the hold-down screw, and screw the two ends screw.Sealing ring is embedded in the cover plate, again cover plate is pressed in base box upper end, screw the screw at 4 angles.Industrial paraffin uses when the access sensor cable.
