Abstract
The utility model, which relates to the technical field of the pipeline detection, relates to a signal clamp, especially to a signal clamp for pipeline detection. The clamp comprises a primary handle and an auxiliary handle, wherein the two handles are hinged together. Front ends of primary handle and the auxiliary handle form a clamp head capable of clamping a pipeline tightly; and rear ends of the two handles form control terminals with convenient operation. The rear end of the positive handle is provided with a wire that can be connected with a transmitter; a plurality of wires are arranged at the transmitter; and signal transmission is formed between the primary handle and the auxiliary handle when the wire and the transmitter are connected. The provided signal clamp has the following advantage: a plurality of signal clamps can be used for simultaneously applying signal currents with the same frequencies and the same phases for a plurality of cables. With utilization of the method for signal applying, the signal current of a target cable can be improved and mutual interference among the plurality of cables can be reduced, thereby improving the detection depth and the detection precision of the cable.
Description
Technical field
The utility model relates to the pipeline detection technical field, is a kind of signal clamp, especially a kind of clamp of the signal for pipeline detection.
Background technology
Pipeline detection, be mainly trend and the buried depth at the situation test geodetic underground pipelines of non-excavation, generally adopts pipe and cable detector to survey.Mainly use transmitter, signal clamp, receiver in the process of pipeline detection, transmitter applies the marking current of a particular frequencies to tested pipeline, generally by the signal clamp, clamp corresponding pipeline, adopt clamp method excitation mode, receiver built-in sensitive coil, the field signal of receiving pipeline, coil produces induction current, thereby calculates trend and the path of pipeline.Although it is more that present pipeline detection has had advantages of, still exists the some shortcomings part in prior art: such as the existing pipeline detection degree of depth is superficial; Multi-cable is in the process of surveying, if only a cable is wherein applied to positioning signal, the induced voltage of other cable can form and disturb the detectable signal of target cable, be difficult to realize detecting accurately.
The utility model content
The purpose of this utility model is for the problems referred to above, provides a kind of reasonable in design, can realize the method accurately detected, the signal clamp avoided interference.
For achieving the above object, the utility model has adopted following technical proposal: a kind of clamp of the signal for pipeline detection, be connected on transmitter, it is characterized in that, comprise the positive handle and the auxiliary-handle that are hinged together, described positive handle and auxiliary-handle front end form the chuck that can clamp pipeline, and its two rear end forms the control end of convenient operation; Described positive handle rear end is provided with the electric wire that can be connected with transmitter, and described transmitter is provided with some wires, can form the signal transmission between positive handle and auxiliary-handle when electric wire is communicated with transmitter.
At above-mentioned a kind of clamp of the signal for pipeline detection, the cross section of described chuck is circular.
At above-mentioned a kind of clamp of the signal for pipeline detection, use, described transmitter is provided with some wires.
Compared with prior art, the utility model has the advantage of: adopt a plurality of clamps to apply the marking current that frequency is identical with phase place to many cables simultaneously.Making to apply in this way the marking current size that signal can improve target cable, reduce interfering with each other between many cables, thereby improve investigation depth and the precision of cable, is a kind of important method that solves push pipe cable detection problem.This method that applies signal is simple, can in the situation that charged the use be applicable to applying widely.
The accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, below will the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described.Apparently, the accompanying drawing in the following describes is only embodiment more of the present utility model, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain according to these accompanying drawings other accompanying drawing.
The clamp structure schematic diagram that Fig. 1 is utility model;
Schematic diagram during use that Fig. 2 is utility model.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is only the utility model part embodiment, rather than whole embodiment.Embodiment based in the utility model, those of ordinary skills are not paying under the creative work prerequisite the every other embodiment obtained, and all belong to the scope of the utility model protection.
As illustrated in fig. 1 and 2, a kind of clamp of many signals for pipeline detection using method, comprise the positive handle 1 and the auxiliary-handle 2 that are hinged together, described positive handle and auxiliary-handle front end form the chuck 3 that can clamp pipeline, and its two rear end forms the control end of convenient operation; The cross section of formed chuck is circular, is convenient to be connected 4 with the pipeline of various cross sectional shapes, and described chuck adopts the permalloy material.Chuck also can be controlled by mechanical drive or electronic control, opens or the closure signal clamp, by under the control well of ground or the folding of the eminence signal clamp workload of with the minimizing personnel, going into the well and climbing.Described positive handle rear end is provided with the electric wire that can be connected with transmitter 5, and described transmitter is provided with some wires, is provided with three in the technical program, can form the signal transmission between positive handle and auxiliary-handle when electric wire is communicated with transmitter.Electric wire is connected on transmitter, during use, by using a plurality of clamps, with transmitter, is connected, and with a plurality of signal clamps, applies the positioning signal of same frequency, same phase, same intensity to many cables simultaneously, thereby reaches the purpose that strengthens the signal reduce disturbance.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
