It should be understood that the specific embodiments described herein are only used to illustrate and explain the present disclosure and are not intended to limit the present disclosure.

[0023] Example 1

[0024] like Figure 1 - Figure 3 As shown, the utility model proposes a blasting drilling angle measuring instrument, including: a base plate 1, a mounting base 2, an adjustment component 3, a rod body 4 and a connecting component 5; the base plate 1 is connected to the mounting base 2; the adjustment component 3 is connected to one side of the mounting base 2; the adjustment component 3 includes a shell 301, the shell 301 is connected to the box body 302 and an electric push rod 303 is installed inside; the shell 301 is hollow inside and is connected to a connecting shell 304, and an opening a is provided at one end for the connecting shell 304 to move; sliders a305 are connected to both sides of the outer wall of the connecting shell 304, the driving end of the electric push rod 303 is connected to the rod body 4, and the outer wall of the rod body 4 is provided with a scale; the connecting component 5 is connected to the outer wall of the rod body 4. By connecting the adjustment component 3 and the rod body 4, it is convenient to use the adjustment component 3 to adjust the applicable length of the rod body 4, and the connection component 5 is installed in conjunction with the scale reading after measurement, which is convenient for use in measuring the blasting drilling angle of different depths, and conveniently improves the connection and coordination of the components of the blasting drilling angle measuring instrument, and facilitates improving the accuracy of blasting drilling angle measurement; the interior of the shell 301 and the box body 302 are hollow and the connection is provided with an opening to communicate with each other, so that the electric push rod 303 is installed inside, which facilitates the connection and coordination of the components of the adjustment component 3.

[0025] To further illustrate, the housing 301 is provided with chute a on both sides of its inner wall, which is used to allow slider a305 to move up and down. The connecting housing 304 is provided with chute b on both sides of its inner wall, which is used to allow slider b to move up and down. Sliders b are arranged on both sides of the outer wall of the upper end of the rod body 4 to stabilize the adjustment of the applicable length. During the process of adjusting the rod body 4 to adapt to the measurement height, the slider a305 is synchronously adjusted and moves along the chute, facilitating more stable adjustment. Furthermore, the slider b simultaneously moves along the chute b, facilitating adjustment of the applicable length according to different needs for measuring the angular depth of the blasting drill hole. Based on the adjustment of the applicable length, the elongated chute a and chute b of the connecting housing 304 and the housing 301 cooperate for guidance and positioning, conveniently improving the coordinated use of the components of the blasting drill hole angle measuring instrument and enhancing the stability of the adjustment of the applicable length.

[0026] To further illustrate, the connecting assembly 5 includes a sleeve 501 attached to the periphery of the rod body 4. The sleeve 501 is connected to a mounting block 502, which is provided with a through-hole a. The mounting block 502 is connected to a connecting block 503, which is connected to a support frame 504, which is connected to a reading ring 505.

[0027] Further, the mounting block 502 and the connecting block 503 are detachably connected. Bolts are passed through through hole a of the mounting block 502 and through hole b of the connecting block 503, with through hole a and through hole b facing each other. The bolts secure the mounting block 502 and the connecting block 503, thereby connecting the reading ring 505 to the rod body 4. The rod body 4 is then inserted into the blasting borehole to be measured. After the measurement is completed, the reading ring 505 is installed and adjusted to the relative scale to read the scale.

[0028] Example 2

[0029] like Figure 2 The present invention provides a blasting drilling angle measuring instrument. Based on the above embodiments, this embodiment further describes in detail specific components such as the base plate 1 and the mounting base 2, as well as the matching method.

[0030] To further illustrate, the base plate 1 is connected to the support plate 101, which is provided with an insertion slot. The support plate 101 is connected to the connecting plate 102, and the lower portion of the connecting plate 102 is connected to the mounting plate 103 and one side is connected to the guide plate 104. The support plate 101 and the guide plate 104 are arc-shaped structures, so that the upper inner wall of the support plate 101 and the shell 301 are closely connected. The guide plate 104 is connected to the support plate 101 according to the use requirements, so that the guide plate 104 is connected to the outer wall of the connecting shell 304. When the connecting shell 304 is adjusted to the applicable length, the guide plate 104 is installed to facilitate the movement and guidance of the connecting shell 304, while also providing support for the connecting shell 304, further improving the stability of the adjusted applicable length, and thereby increasing the use of the rod body 4 for blasting drilling angle measurement.

[0031] Further explanation: Mounting plate 103 is connected to a plug rod that is movably connected to the plug slot. Mounting plate 103 is detachably connected to one side of base plate 1. Bolts penetrate mounting plate 103 and connect the bolts to one side of base plate 1 to connect mounting plate 103 to base plate 1. The plug rod moves synchronously within the plug slot, facilitating increased stability of the connection between mounting plate 103 and base plate 1 and improving the usability of the support base of the blasting drilling angle measuring instrument.

[0032] Further explanation: Mounting base 2 is connected to an electronic goniometer 201 for measuring blasting drill hole angles. A housing 301 is detachably connected to one side of mounting base 2. Electronic goniometer 201 includes a sensor for acquiring angle information. This sensor is typically manufactured using MEMS technology, or micro-electromechanical systems (MEMS), a publicly available technology that will not be described in detail. The electronic goniometer 201 measures drill hole angles. The reading ring 505 and the scale on the periphery of the rod 4 coordinate to measure both the angle and length of the drill hole. This simple structure allows for quick and easy operation. Furthermore, in conjunction with the adjustment assembly 3 and base plate 1, the sensor achieves excellent measurement accuracy.

[0033] The working principle of the present invention is as follows: the length of the measuring instrument is adjusted according to the blasting borehole to be measured, and the electric push rod 303 is started, and the driving end of the electric push rod 303 causes the rod body 4 to move into the borehole, and the rod body 4 drives the sleeve 501, and the sleeve 501 is connected to the mounting block 502 and the connecting block 503, and the connecting block 503 drives the support frame 504, and the support frame 504 drives the reading ring 505, which extends into the borehole. After the measurement is completed, the rod body 4 is taken out of the borehole, and the sleeve 501 is first inserted into the borehole. Move to the desired reading scale position, then connect the support frame 504 and the sleeve 501 through the installation block 502 and the connecting block 503. The support frame 504 drives the reading ring 505, and the reading ring 505 reads the drilling depth scale. Then the electronic goniometer 201 uses the sensor. The sensor contains a tiny accelerometer and gyroscope for measuring the acceleration and angular velocity of the object. By measuring the changes in these parameters, the angle difference can be calculated to achieve the purpose of measuring the blasting drilling angle.

[0034] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited thereto. Various changes can be made within the knowledge scope of those skilled in the art without departing from the purpose of the present invention.
