Outer clamping type low-frequency antenna walking support for ground penetrating radar

Abstract

The invention discloses an outer clamping type low-frequency antenna walking support for ground penetrating radar. The support comprises a main rod, supporting rods, lifting shafts, wheels and buckles. The main rod and the supporting rods are all hollow rods, the supporting rods are arranged at the two ends of the main rod respectively, glass steel pipes are inserted into hollow cavities of the main rod and the supporting rods, the ends, connected with the main rod, of the supporting rods are provided with communicating holes for fixing the lifting shafts, the top ends of the lifting shafts penetrate through the communicating holes to be fixedly connected with the supporting rods, the tail ends of the lifting shafts are fixedly connected with the wheels through wheel supports, the buckles are fixedly arranged on the outer sides of the supporting rods, and the buckles are used for fixing a low-frequency antenna. The outer clamping type low-frequency antenna walking support is a detachable support device, the low-frequency antenna can be conveniently fixed or dismounted, the span of the support can be adjusted according to the interval between a receiving antenna and a transmitting antenna, the height of the wheels of the support can be adjusted, the support can freely steer during walking, and the flexibility and the use portability of the support are considered to the maximum degree while the strength of the support is guaranteed.

Description

technical field [0001] The invention relates to the technical field of geological radar detection applications, in particular to an externally clamped low-frequency antenna walking bracket for ground penetrating radar. Background technique [0002] Ground Penetrating Radar (GPR) is a fast, efficient and nondestructive geophysical prospecting method. Ground-penetrating radar uses one transmitting antenna to transmit high-frequency electromagnetic waves, while the other antenna receives the reflected waves from the interface of the underground target medium, and then analyzes and processes the acquired data to obtain the distribution status of underground targets. With the increase in the demand for large-distance detection, especially the advanced detection of mines requires a detection distance of 50m, most ground-penetrating radar antennas adopt low-frequency designs, and the corresponding low-frequency antennas become larger in physical size. At present, low-frequency ant...

Problems solved by technology

At present, low-frequency antennas are used for detection, which is mainly dragged manually. The lower surface of the antenna shell directly rubs against the ground. On the one hand, noise is introduced in the detection, and on the other hand, it also increases the difficulty of the detection work and affects the service life of the antenna. Therefore, In order to facilitate the application of large-scale low-frequency antennas for detection, it is urgent to design and develop a low-frequency antenna walking bracket for ground penetrating radar
