Description

Technical Field

[0001] The utility model relates to the technical field of measuring boreholes or wells, in particular to a blasthole depth measuring device for mining blasting. Background Art

[0002] When mining, it is necessary to drill blastholes in the mine and mine by blasting. When drilling blastholes, it is necessary to measure the depth of the blastholes. However, the existing blasthole depth measuring mechanisms still have the following problems when detecting blastholes: first, it is not convenient to install on the top of the blasthole; second, the blasthole depth measuring mechanism cannot be positioned at the center of the blasthole. When the blasthole depth measuring mechanism measures at an eccentric position, the reflected ultrasonic wave is likely to contact the inner wall of the blasthole first, resulting in inaccurate measurement. Therefore, a blasthole depth measuring device for mining blasting is proposed. Utility Model Content

[0003] In order to solve at least one of the above-mentioned technical shortcomings, the utility model provides a blasthole depth measuring device for mining blasting, including a rechargeable battery, a display controller and an ultrasonic generator. The rechargeable battery and the ultrasonic generator are fixed inside an outer cylinder, and the display controller is fixed on the upper surface of the outer cylinder. The outer cylinder is cylindrical, hollow inside, and has a through bottom. The outer wall of the outer cylinder is evenly provided with four rotating grooves with through bottoms, and a rotating rod is connected to the top of the rotating groove by a hole-shaft matching manner.

[0004] Furthermore, the outer wall of the outer tube is evenly provided with four inwardly concave airbag grooves, and airbags made of elastic material are arranged inside the airbag grooves. The four airbags are connected through an air guide tube.

[0005] Furthermore, an ultrasonic generator, an air pump and a rechargeable battery are arranged inside the outer tube in sequence from bottom to top, and the air pump is connected to the airbag through an air guide tube.

[0006] Furthermore, the outer surface of the airbag is made of elastic material, and the contact surface of the airbag and the airbag groove is made of plastic. Beneficial Effects

[0007] During quick installation, the bottom end of the rotating rod is bent outward to rotate the rotating rod to a position perpendicular to the outer wall of the outer tube, and the outer tube is placed inside the blast hole so that the four rotating rods can be supported on the top edge of the blast hole to complete the overall installation and achieve quick installation. Through the rotating setting of the rotating rod, when not in use, the rotating rod can be stored into the rotating groove by rotating the rotating rod for easy storage.

[0008] When the airbag is inflated, only the outer surface of the airbag expands outward, and the four airbags expand at the same time, so that the airbags can be pushed in all directions at the same time. Because the four airbags are connected through the air duct, the pressure inside the four airbags is the same, and the thrusts generated by the four airbags are connected. Under the action of the same thrust, the outer tube can be located exactly in the center of the bore, so that the ultrasonic generator is located in the center of the bore. When the ultrasonic generator is measuring, the ultrasonic wave generated by the ultrasonic generator can be parallel to the inner wall of the bore, ensuring that the ultrasonic wave can be emitted to the bottom of the bore, so that the detection is accurate.

[0009] The realization of the purpose, functional features and advantages of the present invention will be further described in conjunction with embodiments and with reference to the accompanying drawings. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0017] Please refer to Figures 1 to 6 ;

[0018] This embodiment provides a blasthole depth measuring device for mining blasting, referring to Figures 1 to 6 , including a rechargeable battery 6, a display controller 2 and an ultrasonic generator 4, the rechargeable battery 6 and the ultrasonic generator 4 are fixed inside the outer tube 1, the display controller 2 is fixed to the upper surface of the outer tube 1, the outer tube 1 is cylindrical, hollow inside, and has a bottom that penetrates, the outer wall of the outer tube 1 is evenly provided with four rotation grooves 102 with bottoms that penetrate, and the top of the rotation groove 102 is connected with a rotation rod 103 by a hole-shaft matching method;

[0019] In the specific implementation, when performing rapid installation, the bottom end of the rotating rod 103 is bent outward to rotate the rotating rod 103 to a position perpendicular to the outer wall of the outer cylinder 1, and the outer cylinder 1 is placed inside the blast hole so that the four rotating rods 103 can be supported on the top edge of the blast hole, and the overall installation is completed to achieve rapid installation;

[0020] The rotating rod 103 is rotatably arranged, and when not in use, the rotating rod 103 can be stored into the rotating groove 102 by rotating the rotating rod 103 for easy storage.

[0021] For further reference, Figure 3 The outer wall of the outer tube 1 is evenly provided with four concave airbag grooves 101, and the airbag grooves 101 are provided with airbags 3 made of elastic material inside, and the four airbags 3 are connected through air guide tubes;

[0022] In specific implementation, when positioning the center of the blast hole, the interior of the airbag 3 is inflated, so that the airbag 3 expands inside the airbag groove 101, and the airbag 3 expands outward to support the inner wall of the blast hole. Because the four airbags 3 are connected through the air duct, the pressure inside the four airbags 3 is the same, so that the thrusts of the four airbags 3 on the inner wall of the blast hole are the same. Under the action of four identical thrusts, the outer tube 1 is pushed to the center of the blast hole to complete the positioning, and the measurement accuracy is improved through positioning.

[0023] For further reference, Figure 2 and Figure 4 The outer tube 1 is provided with an ultrasonic generator 4, an air pump 5 and a rechargeable battery 6 from bottom to top, and the air pump 5 is connected to the air bag 3 through an air guide tube;

[0025] Furthermore, the outer surface of the airbag 3 is made of elastic material, and the contact surface of the airbag 3 and the airbag groove 101 is made of plastic;

[0026] In a specific implementation, after the airbag 3 is inflated, only the outer surface of the airbag 3 expands outward, and the four airbags 3 expand at the same time, so that the airbags 3 can be pushed to the surroundings at the same time, and because the four airbags 3 are connected through the air duct, the pressure inside the four airbags 3 is the same, and the thrusts generated by the four airbags 3 are connected. Under the action of the same thrust, the outer tube 1 can be located exactly at the center of the blast hole, so that the ultrasonic generator 4 is located at the center of the blast hole, and when the ultrasonic generator 4 is measuring, the ultrasonic wave generated by the ultrasonic generator 4 can be parallel to the inner wall of the blast hole, ensuring that the ultrasonic wave can be emitted to the bottom of the blast hole, so that the detection is accurate.
