Description

Technical Field

[0001] The utility model relates to a scanning device, in particular to a portable ultrasonic scanner for vertical blast holes. Background Art

[0002] After the perforation operation of open-pit bench deep-hole blasting, it is necessary to inspect the quality and formation of blast holes. In the prior art, a borehole gauge or a blast hole scanner is usually used to detect the formation quality of vertical blast holes. The blast hole scanner can perform real-time scanning on the drilling quality and formation of vertical blast holes during blasting construction operations, and use three-dimensional digital modeling technology to visualize the internal formation of the blast holes. The blast hole scanners in the prior art are usually large in size. In the vertical blast holes at the blasting construction site, the working environment is harsh with a lot of debris and sediment, the operating space is narrow and easy to scratch, and some vertical blast holes are arranged in a tricky position. It is difficult for large blast hole scanning equipment to scan them.

[0003] The Chinese utility model patent with the publication number CN207280442U discloses an underground cavity three-dimensional structure detection device, which includes a main machine and a probe connected to the main machine through a cable. The cable is wound around a winch. During use, the probe is lowered into the underground cavity through the winch for scanning. However, in actual applications, the vertical blast holes are not necessarily perpendicular to the horizontal plane. For example, in slope blasting, most of the vertical blast holes in blasting construction are not perpendicular to the horizontal plane but have a certain inclination angle. Since the probe in this patent can only be lowered vertically and cannot adjust the movement direction of the probe, it is not suitable for scanning and detecting vertical blast holes with an inclination angle.

The camera module 631 is configured with an LED flash, which can visualize the internal situation of the blast hole, and the result can also be used as the basis for blast hole modeling and rendering. The structures of the camera module 631, the ultrasonic detection module 632, and the laser ranging module 634 all belong to the prior art.

[0041] The cable 70 is housed in the bendable and shape - setting sleeve 50. One end of the cable 70 is electrically connected to the probe 60, and the other end is electrically connected to the master control component 30 to achieve the transmission of signals and the like between the probe 60 and the master control component 30. In this embodiment, one end of the cable 70 is electrically connected to the first adapter. Through the cooperation of the first adapter and the second adapter, the electrical connection with the camera module 631, the ultrasonic detection module 632, and the ranging module 634 of the probe 60 is achieved. The structures of the first adapter and the second adapter belong to the prior art. For example, the structures of the first adapter circuit board and the second adapter circuit board disclosed in the Chinese utility model patent with the publication number CN220344530U can be adopted. The end of the cable 70 far from the probe 60 is electrically connected to the Raspberry Pi 4B main control board of the controller 32 via the first wire passing port 311. In addition, in this embodiment, a wire passing hole 213 is correspondingly provided on the disk body 21 of the protective shell 20 for the first wire passing port 311. The cable 70 passes through the wire passing hole 213 and the first wire passing port 311 in sequence and then is electrically connected to the Raspberry Pi 4B main control board. The first end of the bendable and shape - setting sleeve 50 can also be fixed on the inner wall of the disk body 21, and a sufficient length is reserved between the first end of the bendable and shape - setting sleeve 50 and the winding disk 41 so that the movement of the winding disk 41 will not be affected after the cable 70 is connected to the controller 32.

[0042] When the portable ultrasonic scanner for vertical blast holes is in use, the support plate 224 at the free end of the extension arm 22 can be stuck in the blast hole. According to the inclination angle of the vertical blast hole, the protective shell 20 is rotated through the handle 24 and the like, so that the extension arm 22 is substantially parallel to the length direction of the vertical blast hole. Then, the adjustment bracket 23 is rotated to an appropriate angle, and then the adjustment bracket 23 is supported on the ground to support the portable ultrasonic scanner for vertical blast holes to complete the fixation.

[0043] After the portable ultrasonic scanner for vertical blast holes is fixed, the winding disk 41 is driven to rotate by the winding driving member 43 to release the bendable and shape - setting sleeve 50, so that the probe 60 extends into the blast hole to be detected and moves downward to scan the blast hole. Since the probe 60 is connected to the bendable and shape - setting sleeve 50, when the bendable and shape - setting sleeve 50 extends, the bendable and shape - setting sleeve 50 wound on the winding disk 41 is converted into a straight bendable and shape - setting sleeve 50 parallel to the extension arm 22 through the straightening channel 221. Also, since the extension arm 22 is parallel to the inclination direction of the vertical blast hole, when the bendable and shape - setting sleeve extends, it can drive the probe 60 to move along the inclination direction of the vertical blast hole, thereby realizing the scanning of the vertical blast hole with an inclination angle.

[0044] When the above-mentioned portable ultrasonic scanner for vertical blast holes is detecting, the ultrasonic detection module 632 is used to perform ultrasonic scanning on the blast holes to provide data support for three-dimensional modeling. In this embodiment, multiple groups of ultrasonic detection modules 632 are arranged along the circumferential direction of the probe 60. Using multiple groups of ultrasonic detection modules 632 as scanning modules, there are fewer dead angles during operation, which is beneficial to improving the accuracy of blast hole digital modeling; the ranging module 634 can measure and output the blast hole depth information through laser ranging, and the distance information transmitted in real time during operation is used as the basis for the controller 32 to control the winding drive 43 to prevent the probe 60 from touching the bottom and being damaged; the camera module 631 can visualize the internal situation of the blast hole. Through the camera module 631 and the ranging module 634, image data and distance information are collected in real time, supplemented by the ultrasonic detection module 632 to scan the blast hole wall in real time to complete the real-time scanning and modeling task of the blast hole. After the scanning work is completed, the winding drive 43 drives the winding disc 41 to rotate to wind the bendable and shapeable sleeve 50, so as to facilitate the transportation of the portable ultrasonic scanner for vertical blast holes to scan the next blast hole.

[0045] In the portable ultrasonic scanner for vertical blast holes of this embodiment, two groups of pulley sets 25 are provided in the straightening channel 221. Through the rolling contact between the two groups of pulley sets 25 and the bendable and shapeable sleeve 50, it can not only guide the movement of the bendable and shapeable sleeve 50, but also make it easier to straighten the bendable and shapeable sleeve 50 wound on the winding disc 41.

[0046] In the portable ultrasonic scanner for vertical blast holes of this embodiment, through the cooperation of the extension arm 22, the adjustment bracket 23 and the bendable and shapeable sleeve 50, the movement direction of the probe 60 can be adjusted by rotating the protective shell 20, and it can adapt to the scanning tasks of vertical blast holes with different inclination angles. In addition, the arc-shaped support plate 224 provided at the free end of the extension arm 22. During use, by contacting the blast hole with the arc edge of the support plate 224, the rotation of the protective shell 20 can be made more convenient and smooth. The portable ultrasonic scanner for vertical blast holes can accurately scan vertical blast holes and present the scanning results in a three-dimensional digital manner, and can make the internal forming situation of the blast hole more visual, facilitating the quality inspection work of the blast hole. In addition, the overall structure of the portable ultrasonic scanner for vertical blast holes is compact, which is convenient for carrying and using.

[0047] It can be understood that in other embodiments, the total control component 30 can also be installed on the disc body 21.

[0048] It can be understood that the controller 32 is not limited to this embodiment, and it can also adopt other structures or models of controllers in the prior art, and the present invention does not make any restrictions.

[0049] It can be understood that the rewinding driving member 43 is not limited to the motor in this embodiment. For example, in other embodiments, the rewinding driving member 43 is a handle fixedly connected to the connecting shaft 45. When in use, the user drives the rewinding reel 41 to rotate through the handle to manually control the lowering action of the probe 60.
