Technical field
The utility model relates to the geophysical exploration device field using radar pulse electromagnetic wave detection rock crack, cavity, particularly detects radar installations in the hole in rock crack and cavity.Emitting antenna and receiving antenna is used to detect rock crack and cavity in the borehole.
Background technology
During due to ground ground penetrating radar detection underground rock stratum crack and cavity, radar wave must penetrate overlayer and zone of weathering, reflect after meeting crack and cavity, reflection wave is got back to ground through this layer again and is received, and these are by the medium stratum that penetrates, and often conductivity is larger, thus limit the propagation distance of radar signal, cause investigative range limited, some buries darker rock crack, cavity cannot detect and obtain.In such cases, if carry out radar detection in the borehole, detection coverage can be made larger, contribute to better detecting darker rock crack and cavity.
Utility model content
The technical problems to be solved in the utility model is the problem be restricted at underground propagation for radar signal, there is provided a kind of and detect radar installations in the hole in rock crack and cavity, be one not collapse hole structure, in hole, emitting antenna and receiving antenna can move up and down unobstructed.
employing technical scheme is:
Radar installations in the hole in detection rock crack and cavity, comprises radar.
its technical essential is:
Radar comprises data processing host, emitting antenna and receiving antenna.
Emitting antenna is positioned at below receiving antenna.Emitting antenna and receiving antenna are integrally connected.
Emitting antenna lower end is hammered into shape by web member be connected with guiding.
Counter is installed at bracing frame top.
The winding of Transmission Fibers cable is on the wire spool of counter.
The counter interface of counter is connected with the host count device interface of data processing host by the first data line.
Emitting antenna is connected with data processing host by Transmission Fibers cable with receiving antenna, and emitting antenna and receiving antenna are positioned at protection casing.
The model of described radar: RAMAC/GPR/BH.Described counter model: S/N45609.
The computer interface of described data processing host is connected with the com interface of computing machine by the second data line.
