Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of radio wave detection perspective instrument, in particular, to a radio wave detection perspective instrument applied to underground mine. BACKGROUND

[0002] The radio wave perspective instrument adopts a separate mode of transmission and reception in construction engineering, that is, detection is carried out in the upper and lower roadways of the working face, one roadway transmits (transmission roadway), and the other roadway receives (receiving roadway). When the transmission of one roadway is completed, the double roadway exchange is required, that is, the original transmission roadway becomes the receiving roadway, and the receiving roadway becomes the transmission roadway. In this process, the signal transmitted by the transmitter passes through tens to hundreds of meters of coal seam and reaches the receiving roadway, which is received by the receiver of the receiving roadway. However, in actual use, there are still many shortcomings, such as the existing radio wave perspective instrument cannot quickly and conveniently adjust the height and angle during use, thereby being inconvenient for detecting different positions inside the roadway, and the installation or disassembly process of the radio wave perspective instrument is time-consuming and laborious.

[0003] Through retrieval, the existing patent (publication number: CN212160105U) discloses a mining radio wave perspective instrument mounting device, which comprises a bottom plate, a height adjusting assembly and an angle adjusting assembly. The height adjusting assembly comprises a vertical plate, a first sliding rail, a first threaded rod, a second threaded rod, a belt pulley, a first sliding block and a support plate. Two vertical plates are oppositely arranged on the bottom plate, and the first sliding rail is arranged on the inner side of the two vertical plates. The device can quickly and conveniently adjust the height and angle of the radio wave perspective instrument, and is convenient for the installation and disassembly of the radio wave perspective instrument.

[0004] However, there are still some deficiencies in the above-mentioned scheme. Since the radio wave perspective instrument needs to set the receiving and transmitting modules of the radio wave perspective instrument in the adjacent two roadways during actual detection work, and then due to the blockage of the measured ore body between the two roadways, it is difficult to quickly and accurately position the working positions of the receiving and transmitting modules located in different roadways, and the working efficiency is low. Secondly, when detecting the ore body, multiple points often need to be detected, which further increases the difficulty of positioning the receiving and transmitting modules. Moreover, each time the detection point is changed, drilling needs to be performed on the surface of the measured ore body to facilitate the installation and positioning of the receiving and transmitting modules, which is more troublesome and time-consuming.

[0005] Therefore, the present application provides a radio wave detection perspective instrument applied to underground mine. SUMMARY
