Embodiment Construction
[0023] The present invention will be further described below in conjunction with the accompanying drawings. The following examples are only used to illustrate the technical solution of the present invention more clearly, but not to limit the protection scope of the present invention.
[0024] Such as figure 1 As shown, this solution involves a geological detection device for inclined blast holes. In this embodiment, three elastic arms are used, which are evenly distributed at 120°.
[0025] Structurally, the camera cooperates with the searchlight to take clear pictures in the hole. The camera is installed at the front of the device to take pictures of the blast hole, detect the lithology inside the blast hole, and whether there are cracks or caves in the blast hole. The searchlight is installed on the side of the camera to provide The camera provides a light source and transmits the video through the data cable.
[0026] The elastic arm has a built-in spring that provides te...

The invention discloses a geological detection device for inclined blast holes. The device is characterized by comprising a camera, a searchlight, an elastic arm, an elastic wheel, a hollow rod and atraction device. The camera is assembled at the front end of the device. The elastic arm is internally provided with a spring for providing the tension to the outside so as to adapt to blast holes ofdifferent apertures. The elastic wheel is assembled at the end portion of the elastic arm, and the stability of the device in the walking process is guaranteed. The hollow rod provides the power fora manual operation device on one hand, and serves as a data line of the camera on the other hand. According to the invention, based on the cooperation of the elastic arm, the hollow rod and the traction device, the geological environment inside blast holes of different apertures can be detected, wherein the geological environment is composed of in-hole lithological characters, fractures, karst caves and the like. Therefore, different charging amounts can be adopted at different depths inside blast holes according to the geological condition inside holes. As a result, the condition that the ideal blasting effect cannot be realized due to the too-large / too-small explosive loading amount can be avoided.
Description
technical field [0001] The invention relates to a geological detection device for inclined blast holes, which belongs to the technical field of blasting engineering. Background technique [0002] At present, with the improvement of blasting accuracy requirements in geotechnical engineering, under the condition of ensuring that the rock mass can be excavated, it is necessary to carry out fine blasting on the rock mass to generate a small blasting vibration, so as to reduce the impact on the surrounding structures and reserved rock mass. body destruction. [0003] However, during the blasting and excavation of rock mass, in some places with complex geological conditions, the lithology is different at different excavation depths, and fissures are often developed, and some rock masses may even have some geological condition defects such as karst caves. Under such conditions, where it is necessary to drill inclined blastholes, if there are different lithologies and geological de...
