Abstract
The invention relates to a transmitting antenna device of transient electromagnetic equipment, which comprises a fixed link, a support, a framework and an umbrella cover. One end of the framework is hinge jointed with the top of the fixed link, one end of the support is connected with the fixed link and the other end is hinge jointed with the framework. At least one barb in groove shape is equipped on the surface of the framework, and lead is provided in the barb in groove shape of bordering framework completely or alternatively. The lead on the framework forms a concentric ring structure and the umbrella cover is set on the lower surface of the framework. The umbrella cover in the invention can be pulled down at other times and overturned on the fixed link like an umbrella. When using, a knighthead can fold up the umbrella in the shape of an umbrella to form the umbrella cover opposite to the crag into a hollow cabochon. Face the umbrella cover to the surface of the crag, the electropult formed by reticulate lead can generate electromagnetic wave which can penetrate the terrane and return when meet with a hollow, then accepted by accepting device. The invention is characterized by simple structure, high exploration precision, anti-jamming, convenient measurement, easy carrying, flexibility and high precision for measuring coupling, etc.
Description
Technical field
The present invention relates to a kind of transient electromagnetic technology, specifically a kind of transmission antenna device of transient electromagnetic equipment.
Background technology
A large amount of Tunnel Engineering are arranged in China's water conservancy and hydropower, the field of traffic, the Tunnel Engineering geologic hazard is the key factor of restriction constructing tunnel, because the tunnel front geological condition is not clear, unforeseen geologic hazard often appears often, as gushing water, prominent mud, cave in, rock burst and harmful gas etc.In a single day disaster takes place, and the facility that gently then destroy by rush of water flood the tunnel, and normal construction is forced to interrupt; Heavy then cause great casualties, produce enormous economic loss, even therefore some underground works can be forced to suspend or relocate.Transient electromagnetic equipment can carry out constructing tunnel unfavorable geology advanced prediction.Transient electromagnetic method is to utilize earth-free loop line or ground connection line source to underground transmission pulsatile once magnetic field, at pulsatile once magnetic field tempus intercalare, utilizes the method for coil antenna (or ground-electrode) observation secondary inductive loop field.The soluble geological problem of transient electromagnetic method constantly enlarges, and has almost related to the every field of physical prospecting work: ore prospecting, structural exploration, the hydrology and engineering geological survey, environmental surveys and monitoring and archaeology etc.All obtained good result at aspects such as water detection, municipal works, salting of soil and pollution surveys and the chartings of shallow oil structure in recent years.The structure of the antenna in the transient electromagnetic equipment device, performance are the key factors that influences the leading precision of this technology, emitting antenna does not have fixed sturcture substantially at present, all be the on-the-spot four line frames that temporarily are barricaded as, exist received signal poor, move difficulty, transmit and receive electromagnetic field couples poor, measure shortcoming such as waste time and energy, installing/dismounting inconvenience, profile are not attractive in appearance.
Summary of the invention
The present invention is for overcoming above-mentioned the deficiencies in the prior art, provide that a kind of emission is good with received signal, detection accuracy is high, anti-interference, measure make things convenient for, is easy to carry, scalable, the transmission antenna device of measuring the high transient electromagnetic equipment of precision that is coupled.
The objective of the invention is to adopt following technical proposals to realize: a kind of transmission antenna device of transient electromagnetic equipment, comprise fixed bar, support, skeleton and umbrella cover, skeleton one end is articulated in the top of fixed bar, supporting an end is connected with fixed bar, the other end and skeleton are hinged, and the skeleton upper surface is provided with at least one groove shape barb, in the groove shape barb of adjacent skeleton all or be interval with lead, lead on the skeleton is formed the annular concentric structure, and the skeleton lower surface is provided with umbrella cover.
Described skeleton has two at least.
Described fixed bar is provided with lead ring, and the lead ring side is provided with lock screw, and an end of support is connected on the lead ring.
Described skeleton top is provided with longitudinal opening, is provided with lead in the longitudinal opening.
Described umbrella cover is the layer of metal reflector net.
Umbrella cover of the present invention can left behind at ordinary times, overlay on the fixed bar as umbrella, during use, by the lead ring that upwards promotes on the fixed bar support promotion skeleton is strutted umbrella cover, then by the locking of the lock screw on lead ring lead ring, as the umbrella cover of same umbrella, that side umbrella cover relative with crag becomes cancave cambered surface.Umbrella cover is aligned the crag surface, and the emitter that the annular concentric traverse net is formed sends electromagnetic wave and penetrates to run into behind the rock stratum and return when hollow again, is received by receiving trap.Because the emitter surface is provided with the umbrella cover that the metallic reflection net is formed, the emission backward of can avoiding transmitting, and the interference of external signal, the while has also increased the intensity of received signal.That the present invention has is simple in structure, detection accuracy is high, anti-interference, measure make things convenient for, is easy to carry, scalable, measure the precision advantages of higher that is coupled.
