Thus, a feature defined as "first," "second," etc. may explicitly or implicitly include one or more of that feature. In the description of the invention, the meaning of "a plurality" is two or more unless otherwise specified.
In the description of the invention, it is to be noted that, unless otherwise explicitly specified or limited, the terms "mounted", "connected" and "connected" are to be construed broadly, e.g. as being fixed or detachable or integrally connected; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meaning of the above terms in the creation of the present invention can be understood by those of ordinary skill in the art through specific situations.
The invention will be described in detail with reference to the following examples.
A portable cable insulation detection device is shown in figures 1 to 4 and comprises a holding rod 1, wherein a mountain-shaped fixing frame made of insulating materials is arranged at the front end of the holding rod, and a protective cover 20 is arranged on one side, close to the fixing frame, of the holding rod; in order to improve the use safety and avoid electric shock accidents caused by misoperation to the maximum extent, a protective cover is particularly arranged and is generally designed into a U-shaped structure.
The fixing frame comprises a connecting body 2, a main frame body 3 vertical to the connecting body and sub-frame bodies 4 on two sides of the main frame body; the main frame body is provided with a main detection unit 5, and the sub-frame bodies are respectively provided with an auxiliary detection unit 6;
the main detection unit 5 comprises semi-circular detection heads 7 which are hinged with each other through a hinge shaft 18, and the two semi-circular detection heads are connected with one sides which are hinged with each other through a buckle assembly 8; the inner wall of the semicircular detection head is provided with a mounting groove 9, a detection ball 10 is arranged in the mounting groove, and the parts of the semicircular detection head except the mounting groove are provided with insulating layers; generally, the insulating layer adopts a rubber coating or an insulating paint layer to achieve the insulating effect;
each semicircular detection head is internally provided with an electric leakage detection assembly, and an indicator light 17 electrically connected with the electric leakage detection assembly is embedded in each semicircular detection head; the indicator light described herein is typically a neon light.
In an optional embodiment, the position that corresponds the holding rod on the guard shield is equipped with the spout, and the guard shield passes through the gliding installation of spout on the holding rod, can be according to the operating mode that uses, suitably adjust the orientation of covering of guard shield, furthest's promotion security. As for how the protective cover is fixed with the holding rod, a person skilled in the art can design according to the conventional technology, for example, after the opening of the protective cover is adjusted to face towards, the protective cover can be fixed with the holding rod by using a connecting piece such as a screw, and of course, as long as the protective cover is fixed with the holding rod, the protective cover can be ensured to be arranged and moved when in use.
The auxiliary detection unit comprises an extension arm 11, and a guide structure 12 is arranged on one side of the front end of the extension arm, which is different from the main detection unit. When the extending arms on the two sides of the main detection unit are used for moving towards the two ends of the cable in the length direction, the cable is picked up, and the effect that the cable smoothly passes through the two semicircle detection heads is achieved (no matter which side of the cable is detected, the cable can be picked up through the extending arm of the corresponding side auxiliary detection unit, the smooth cable passing through the main detection unit is ensured, and the damage caused by the fact that the cable is bent greatly is avoided). The auxiliary detection unit not only plays a structural transition role, but also effectively avoids the potential safety hazard caused by the fact that the cable is poked by hands unconsciously.
The extending arm is provided with a wire passing groove 13 corresponding to the center of the main detection unit. When the detection device is moved left and right, the position of the cable can be stably kept by utilizing the extension arm on the corresponding side, the smooth entering of the cable into the detection head is ensured, the damage to the detection device is avoided, and the excessive bending of the cable is also avoided.
In an alternative embodiment, as shown in fig. 4, the extending arm includes a main frame and a roller 14 inside the main frame, when the detecting device is moved, since the roller can roll, the friction between the cable and the structural member of the detecting device is reduced, and the smoothness of the cable entering the detecting head can be ensured to the maximum extent.
The guide structure comprises an arc-shaped guide surface 15 and an oblique transition surface 16 connected with the guide surface in a smooth transition mode, and the oblique transition surface and the outer side surface of the stretching arm, which is different from the main detection unit, are in smooth transition. The guide surface extends as far as the end of the free end of the spreading arm. When the device is used, the tail end (tip end) of the extension arm is inserted into the bottom of a cable, the cable is slowly picked up, and then the detection device is slid left and right on the cable, so that the cable can slide to the position of the extension arm main body along the obliquely arranged oblique transition surface (precisely because the guide structure is arranged, the cable can be conveniently approximately maintained at the middle part of the extension arm and cannot stay at the tail end of the extension arm).
In an alternative embodiment, the electrical leakage detecting assembly comprises a wire connected to the indicator light, and the other end of the wire is in internal contact with the corresponding semicircular detecting head. Examine time measuring, utilize the tip of extending arm to slightly pick up the cable, hold the holding rod, remove this detection device, two semicircle detection heads that will open are detained on the cable, detect the head through lock buckle subassembly with two semicircles and fix, detect the head cover in the cable outside in other words with two semicircles, at this moment, hold the grab handle, move detection device along cable length direction, can realize insulating nature detection, in order to reach better detection effect, can be along the cable length direction make a round trip many this detection device that removes repeatedly.
Once the cable has the electric leakage condition, as long as detect ball (metal material) and touch the electric leakage part of cable, can transmit corresponding semicircle with the electric current and detect the head, and then transmit the pilot lamp through the wire, make the pilot lamp sparkle. If the indicator light is not found to be flashing after repeated detection, no electric leakage condition occurs. It should be noted that, in order to avoid the large current from burning the indicator light, a converter may be connected to a wire of the indicator light (i.e., in the prior art, components such as a current stabilizer or a transformer commonly used in the lamp effectively prevent the large current from being damaged, and a person skilled in the art may adapt to the corresponding transformer according to actual conditions, and details are not described here).
The cable insulation detection device is simple in structure, reasonable in design, good in portability, capable of conveniently detecting the insulation of a cable, capable of completing detection operation especially by one hand, time-saving, labor-saving and high in safety.
It is obvious to a person skilled in the art that the invention is not restricted to details of the above-described exemplary embodiments, but that it can be embodied in other specific forms without departing from the spirit or essential characteristics thereof.
The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. Any reference sign in a claim should not be construed as limiting the claim concerned.
