Abstract
Description
Technical field
The utility model belongs to fields such as detection instrument, especially a kind of underground pipeline finder.
Background technology
Along with the urbanization of The development in society and economy and population, the harm of city disaster becomes increasingly conspicuous, the big city and the megalopolis of the development of expanding especially rapidly, and the disaster in city, environmental hazard and man-made disaster are all very serious.The sustainable development of a modern city, must be have safety guarantee, particularly in the face of accident and disaster, can make correct decisions fast and effectively rescue response.So; We will come epistemically underground pipelines in city planning, construction and management of function and status from the strategy for urban development height; Grasp and find out the present situation of City Buried Pipeline; Being the needs of city self socio-economic development, is the needs of urban planning and construction, is to take precautions against natural calamities and deal with the needs of sudden major accident.The normal operation of safeguarding city " lifeline ", ordinary production, life and the social development that guarantees the city people all are of great immediate significance and far-reaching historical meaning." so doing the Urban Buried Pipeline Network construction well is the major issue of benefiting for the descendants, is to have far-reaching strategic importance ".The defective that prior art exists: prior art is to utilize electromagnetic induction principle to survey metal pipe line, electricity/optical cable; And some have the nonmetal pipeline of metal flag line; Shortcoming is when surveying nonmetal pipeline; Must be by nonmetal probe, this method uses relatively effort, needs to invade pipeline inside.
Summary of the invention
The purpose of the utility model is to overcome the deficiency of prior art, and a kind of stable performance, easy to use, underground pipeline finder that precision is high and safe and reliable are provided.
The utility model solves its technical matters and takes following technical scheme to realize:
A kind of underground pipeline finder comprises transmitter, receiver, signal relative analytic apparatus, image display device, audio prompt device, and signal relative analytic apparatus, image display device, audio prompt device cooperate transmitter and receiver to use.Transmitter applies the marking current of a particular frequencies for tested pipeline, utilizes electromagnetic induction principle, confirms accurate position, trend and the buried depth of underground utilities through the Distribution of Magnetic Field of surveying underground utilities; Receiver adopts three horizontal coil differential techniques, and it is steady and audible to receive signal; The signal that the signal relative analytic apparatus adopts the phase identification interface differential technique to receive is analyzed comparison; The phase place of image display device display pipeline, personnel are surveyed in the voice suggestion of audio prompt device.
And described transmitter applies the marking current of a particular frequencies for tested pipeline, adopts direct-connected method, inductive method and three kinds of excitation modes of clamp method.
And, the trend of described detection underground metal pipeline and buried depth, by metal pipe line playback or the playback of cable sheet lead, receiver is used the large size probe detection, and the effective detection range degree of depth can reach 7 meters.
And described transmitter is surveyed the trend and the buried depth of underground non-metal line, adopts the cable core playback, and receiver is with a probe detection, buried depth 1.5 meters with interior and buried depth 2.5 meters with interior cable, the planimetric position error is greater than 5 centimetres.
The advantage and the good effect of the utility model are:
1, this practical underground pipeline finder is surveyed the trend and the buried depth of underground non-metal line; Adopt the cable core playback; Survey the trend and the buried depth of underground metal pipeline, by metal pipe line playback or the playback of cable sheet lead, underground metal pipeline comprises oil pipe, steam pipe, water pipe.
2, this practical new underground pipeline finder receiver adopts state-of-the-art three horizontal coil differential techniques, and filtering interference signals is given prominence to the target pipeline field signal automatically.
3, the utility model is reasonable in design, makes the effect that underground pipeline finder can be brought into normal play, advantage such as have intellectuality, highly sensitive, stable performance, antijamming capability is strong, the detection range scope is big, but widespread use.
Description of drawings
Fig. 1 is the fundamental diagram of the utility model;
Embodiment
Below in conjunction with accompanying drawing the utility model embodiment is done further detailed description:
A kind of underground pipeline finder; As shown in Figure 1; Comprise transmitter, receiver, signal relative analytic apparatus, image display device, audio prompt device, signal relative analytic apparatus, image display device, audio prompt device cooperate transmitter and receiver to use.Transmitter applies the marking current of a particular frequencies for tested pipeline, utilizes electromagnetic induction principle, confirms accurate position, trend and the buried depth of underground utilities through the Distribution of Magnetic Field of surveying underground utilities; Receiver adopts three horizontal coil differential techniques, and it is steady and audible to receive signal; The signal that the signal relative analytic apparatus adopts the phase identification interface differential technique to receive is analyzed comparison; The phase place of image display device display pipeline, personnel are surveyed in the voice suggestion of audio prompt device.
The trend and the buried depth of the detectable underground utilities of this instrument; Pipeline corrosion protection insulation course breaking point etc.; Survey the trend and the buried depth of underground non-metal line, adopt the cable core playback, with a probe detection; Buried depth 1.5 meters with interior and buried depth 2.5 meters with interior cable, the planimetric position error is greater than 5 centimetres; Survey the trend and the buried depth of underground metal pipeline, by metal pipe line playback or the playback of cable sheet lead, underground metal pipeline comprises oil pipe, steam pipe, water pipe, uses the large size probe detection, and effectively investigation depth can reach 7 meters; Survey the breaking point of underground utilities anti-corrosion insulating layer; Send an electromagnetic wave signal by transmitter to underground metal pipeline; When there was breaking point in the underground utilities anti-corrosion insulating layer, this place and the earth short circuit mutually produced leakage current to radiation all around; And radiation is the strongest above breaking point, finds out the breaking point of pipeline corrosion protection insulation course according to this principle; Underground pipeline finder is filtering interference signals automatically, outstanding target pipeline field signal, thereby it is steady and audible to receive signal, can really realize the accurate location and the depthkeeping of pipeline.
It is emphasized that; The described embodiment of the utility model is illustrative; Rather than it is determinate; Therefore the utility model is not limited to the embodiment described in the embodiment, every by those skilled in the art according to other embodiments that the technical scheme of the utility model draws, belong to the scope of the utility model protection equally.
