Embodiment Construction

[0015] This anti-electrical noise external grounding wire device that can eliminate the electrical noise interference encountered by the side-scan sonar C3D during the actual measurement process includes a bobbin 1 , a section of BV copper wire 2 , and two insulating sleeves 3 .

[0016] A. The bobbin 1 is a side-mounted "worker"-shaped member with flat bottoms at both ends, and a stainless steel upper opening ring hook 11 is respectively set on both ends of the shaft body in the middle of the bobbin;

[0017] B. The length of the BV copper wire is about 4-5m, and there is a protruding ring every 0.5m, and there are multiple equally spaced perforations on the ring; One end is connected to the nose, and the other end is connected to the alligator clip 22.

[0018] The alligator clip 22 and the wire lug 23 are each provided with an insulating sheath 3 .

[0019] The specifications of the insulating sheath are configured according to the corresponding wire lugs and alligator cli...

Abstract

The invention relates to a circumscribed earthing wire device with electrical noise interference resistance, which comprises a spool, a BV copper line, an insulation sleeve, and is characterized in that the spool is a laterally arranged I-shaped structural member the two ends of which are flat; the two ends of a shaft body in the middle of the spool are respectively provided with a stainless-steel ring-shaped hook with an upper opening in a sheathed mode; the length of the BV copper line is about 4-5m; a projection ring is arranged every other 0.5m; a plurality of perforations are arranged on the ring at equal interval; the BV copper line is sequentially wound on the shaft body in the middle part of the spool; and one end of the BV copper line is connected with a wiring nose while the other end is connected with an alligator clip.

Description

technical field [0001] The invention relates to an external grounding device, in particular to an external grounding wire device capable of resisting electric noise interference. Background technique [0002] At present, the technology of grounding wire is relatively mature, and the use is also very common. For example, the Chinese national patent grounding wire device, whose patent number is ZL200720069269.0, is used to connect with the cable and lead high-voltage electricity into the ground during the operation process. The way it is connected to the cable is pre-twisted However, equipment such as sonar is not a cable, so it is difficult to connect, and the working environment of sonar is in a water body. Most of the noise sources that affect the work of sonar are also water bodies. Connecting cables have different requirements and are not designed for electrical noise interference rejection of sonar devices. Contents of the invention [0003] The purpose of the presen...
