[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0019] Please see Figure 1-3 In this embodiment of the utility model, a crack measuring device for geological exploration includes a first measuring rod 1, a second measuring rod 2 and a third measuring rod 3. The rear end of the first measuring rod 1 and the rear end of the second measuring rod 2 are both provided with threaded grooves 5. The front end of the second measuring rod 2 and the front end of the third measuring rod 3 are both provided with threaded heads 4. The first measuring rod 1 and the second measuring rod 2, as well as the second measuring rod 2 and the third measuring rod 3, are all threadedly connected by the threaded heads 4 and the threaded grooves 5.
[0020] The first measuring rod 1, the second measuring rod 2, and the third measuring rod 3 are all round rods with the same diameter, which makes it easier for the movable plate 7 and the slider 10 to slide on the three measuring rods, making the sliding smoother.
[0021] Please see Figure 1-2 A fixed plate 6 is installed on the front of the first measuring rod 1, and a front measuring head 8 is installed on the bottom of the fixed plate 6. A movable plate 7 and a slider 10 are slidably arranged on the third measuring rod 3, respectively. A rear measuring head 9 is installed on the bottom of the movable plate 7. A distance sensor 13 is installed on the movable plate 7. A connecting rod 11 is installed between the movable plate 7 and the slider 10. A handle 12 is installed on the slider 10. A display 14 is installed on the side of the slider 10.
[0022] The front end face of the ranging sensor 13 is flush with the front end face of the movable plate 7. This design is to ensure that the data detected by the ranging sensor 13 is more accurate. The ranging sensor 13 and the fixed plate 6 are set opposite each other. The ranging sensor 13 is an ultrasonic sensor. This design is to ensure that the ultrasonic waves emitted by the ranging sensor 13 can be blocked by the fixed plate 6 and reflected back.
[0023] The diameters of the front measuring head 8 and the rear measuring head 9 are equal to the thicknesses of the fixed plate 6 and the movable plate 7. This design is to ensure that the front and rear ends of the front measuring head 8 are vertically aligned with the front and rear ends of the fixed plate 6, and that the front and rear ends of the rear measuring head 9 are vertically aligned with the front and rear ends of the movable plate 7.
[0024] The rear end of the third measuring rod 3 is equipped with a battery compartment 15, which contains a rechargeable battery. A charging port 16 is located at the rear of the battery compartment 15. The charging port 16 is a USB port and is used by personnel to charge the rechargeable battery. An indicator light is also provided on the battery compartment 15 to show whether the battery is fully charged.
[0025] The rechargeable battery powers the display 14 and the distance sensor 13. The display 14 is electrically connected to the distance sensor 13 to display the measurement data in real time for easy viewing by the measurement personnel.
[0026] The working principle of this utility model is as follows:
[0027] In use, first adjust the length of the entire measuring device according to the size of the bottom crack. When adjusting the length, simply rotate the two adjacent measuring rods to detach or combine them. The length of the entire measuring device can be adjusted by increasing or decreasing the length of the second measuring rod 2. After adjustment, first push the measuring rod to move on the crack and make the front measuring head 8 at the bottom of the fixed plate 6 abut against one side of the crack. Then, keep the measuring device in the same position with one hand and hold the handle 12 with the other hand to push the slider 10 to slide on the measuring rod. The slider 10 drives the movable plate 7 to slide along the measuring rod through the connecting rod 11, so that the rear measuring head 9 at the bottom of the movable plate 7 abuts against the other side of the crack. At this time, the distance sensor 13 measures the distance to the fixed plate 6. This distance is displayed on the display 14 as the measured crack length or width.
[0028] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
