Description

Technical Field

[0001] This utility model relates to the field of geological surveying technology, and in particular to a portable hydrogeological fracture measuring device. Background Technology

[0002] In hydrogeological and environmental geological surveys, measuring geological fractures is a crucial task. Accurately measuring parameters such as the width, depth, and length of geological fractures is key to analyzing geological structural stability, groundwater migration patterns, and assessing geological hazards. However, existing geological fracture measurement devices have many shortcomings.

[0003] Patent CN214039802U discloses a device for measuring geological fissures in a hydrogeological ring. During measurement, the support legs are placed on both sides of the fissure, and the scales on the left and right sides are placed inside the fissure. The scales are slid so that the left scale is against the left side of the fissure and the right scale is against the right side of the fissure. The reading on the scale pointed to by the left end face of the guide sleeve is the width of the fissure. There is no need to calculate the difference between the scales on the left and right sliders, which improves the efficiency and accuracy of measuring the width of geological fissures.

[0004] However, the patent still has the following defects: because the device is equipped with components such as tension springs, and the scale needs to be slidable above the crossbeam, and because the scale cannot be wound, the length of the scale is less than the length of the crossbeam, which leads to a problem of limited measurement range when the device measures the width of cracks. Utility Model Content

[0005] The present invention aims to provide a portable hydrogeological fracture measuring device to overcome the shortcomings mentioned above.

[0006] In order to achieve the above objectives, the technical solution of this utility model is as follows:

[0007] A portable hydrogeological fracture measuring device, comprising:

[0008] guide;

[0009] A measuring tape connected at one end to one end of the guide rail; and

[0010] A first slider and a second slider are fixedly slidably connected on the guide rail at intervals. Alignment elements for aligning the crack edges are fixedly connected to both the first slider and the second slider. The first slider is fixedly connected to the other end of the measuring tape, and a guide sleeve is fixedly connected to the second slider, the guide sleeve passing through the middle of the measuring tape.

[0011] Furthermore, a clamping block is fixedly connected to the upper surface of the first slider, and the clamping block is fixedly connected to the other end of the measuring tape. The initial value of the scale on the measuring tape and the alignment piece on the first slider are located in the same plane.

[0012] Furthermore, the guide sleeve is fixedly connected above the second slider, and an observation window is provided on the guide sleeve, which is positioned opposite to the scale on the measuring tape.

[0013] Furthermore, a pointer is provided inside the observation window, and the pointer is positioned opposite to the scale on the measuring tape. The alignment member on the second slider is located on the same plane as the pointer.

[0014] Furthermore, the alignment element is a laser, which is used to emit a vertically downward laser. The laser emitted by the laser on the first slider is in the same plane as the initial value of the scale on the measuring tape, and the laser emitted by the laser on the second slider is in the same plane as the pointer.

[0015] Furthermore, both the first and second sliders are threadedly connected with fastening screws, which selectively abut against the guide rail.

[0016] Furthermore, a damping roller assembly is provided at one end of the guide rail, and the damping roller assembly is frictionally connected to the middle of the measuring tape.

[0017] Furthermore, the damping roller assembly includes:

[0018] A roller frame fixedly connected to one end of the guide rail; and

[0019] Two damping rollers are rotatably connected to the roller frame. The two damping rollers are located on the front and rear sides of the measuring tape, respectively, and are in frictional contact with the measuring tape.

[0020] Furthermore, telescopic support legs are fixedly connected to both ends of the guide rail, and a horizontal bubble meter is installed on the guide rail.

[0021] Furthermore, the telescopic support leg includes:

[0022] A support rod whose upper end is fixedly connected to the guide rail, and whose lower end has an external thread structure; and

[0023] A threaded sleeve with its upper end threadedly connected to the lower end of the support rod, and a pad is fixedly connected to the lower end of the threaded sleeve.

[0024] Compared with the prior art, this utility model has at least the following advantages:

[0025] When using it, place the guide rail above the crack and keep it horizontal. By sliding the first and second sliders, align the alignment points below them with the two edges of the crack respectively. The width of the crack can be obtained by reading the scale on the measuring tape at the guide sleeve.

[0026] This device uses a measuring tape as a measuring tool. One end of the measuring tape is fixed on the guide rail, and the other end is fixed by the first slider. It can be freely unfolded according to the crack width, thus greatly expanding the measurement range and meeting the measurement needs of larger crack widths. Attached Figure Description

Detailed Implementation

[0032] 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.

[0033] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0034] Reference Figure 1-3 This utility model provides a portable hydrogeological crack measuring device, the structure of which mainly includes a guide rail 1, a measuring tape 2, a first slider 5, a second slider 6, and an alignment component 7.

[0035] The guide rail 1 serves as the basic support component of the device. During use, it must be placed above the crack and is typically kept horizontal. The guide rail 1 primarily guides the movement of the first slider 5 and the second slider 6. One end of the guide rail 1 has a storage box with an opening in its side wall, through which the intermediate shaft 3 is rotatably connected. One end of the measuring tape 2 is wound around the intermediate shaft 3, which passes through the storage box and is connected to a screw handle 4. The measuring tape 2 is used to measure the crack width. When it needs to be stored, rotating the screw handle 4 rotates the intermediate shaft 3, thus storing the measuring tape 2.

[0036] The first slider 5 and the second slider 6 are fixed at a distance and can slide on the guide rail 1. Alignment pieces 7 are fixedly connected to both sliders. In use, the alignment pieces 7 on the first slider 5 and the second slider 6 are respectively opposite to the edge of the crack. The first slider 5 is fixedly connected to the other end of the measuring tape 2, and the second slider 6 is fixedly connected to a guide sleeve 9, which passes through the middle of the measuring tape 2 and can slide along the middle of the measuring tape 2.

[0037] A clamping block 8 is fixedly connected to the upper surface of the first slider 5. The clamping block 8 is fixed to one end of the measuring tape 2, thereby ensuring that the measuring tape 2 and the first slider 5 are firmly connected. The initial value of the scale on the measuring tape 2 is on the same plane as the alignment piece 7 on the first slider 5.

[0038] The guide sleeve 9 is fixedly connected above the second slider 6. An observation window 10 is provided on the guide sleeve 9, and the observation window 10 is aligned with the scale on the measuring tape 2. A pointer 11 is also provided inside the observation window 10, and the pointer 11 is also aligned with the scale on the measuring tape 2. Furthermore, the alignment piece 7 on the second slider 6 and the pointer 11 are located on the same plane. This design allows for precise reading of the crack width by observing the scale pointed to by the pointer 11 during measurement, making the reading more intuitive and accurate, and effectively avoiding errors caused by inaccurate alignment in existing technologies.

[0039] Alignment element 7 is a laser that emits a vertically downward laser beam. The laser emitted by the laser on the first slider 5 is on the same plane as the initial value of the scale on the measuring tape 2, while the laser emitted by the laser on the second slider 6 is also on the same plane as the pointer 11. By aligning the crack edge with the laser, the crack location can be more accurately positioned, improving measurement accuracy. The use of the laser also makes the operation of aligning the crack edge faster, reducing manual alignment time and further improving the overall efficiency of the measurement.

[0040] Both the first slider 5 and the second slider 6 are connected by threaded fastening screws 12, which can selectively abut against the guide rail 1. When it is necessary to fix the position of the slider, tighten the fastening screws 12 to make them abut against the guide rail 1, thus fixing the slider at a specific position on the guide rail 1; when it is necessary to move the slider, loosen the fastening screws 12. Fixing the slider at all times during the measurement process ensures the stability of the measurement and avoids errors caused by slider movement.

[0041] A damping roller assembly is provided at one end of the guide rail 1, and the damping roller assembly is frictionally connected to the measuring tape 2. The damping roller assembly includes a roller frame 13 fixedly connected to one end of the guide rail 1, and two damping rollers 14 rotatably connected to the roller frame 13. The two damping rollers 14 are located on the front and rear sides of the measuring tape 2, respectively, and are frictionally connected to the measuring tape 2. This design can provide a certain damping effect on the movement of the measuring tape 2, ensuring that one end of the measuring tape 2 remains taut during the movement of the first slider 5 towards the other end of the guide rail 1, thereby ensuring the accuracy of the measurement.

[0042] Telescopic support legs are fixedly connected to both ends of the guide rail. Each telescopic support leg includes a support rod 16 whose upper end is fixedly connected to the guide rail 1, and the lower end of the support rod 16 has an external thread structure; and a threaded sleeve 17 whose upper end is threadedly connected to the lower end of the support rod 16, with a pad 18 fixedly connected to the lower end of the threaded sleeve 17. By adjusting the length of the telescopic support legs, the height of the guide rail 1 can be adjusted to adapt to different measurement environments. Simultaneously, a bubble level 15 is installed on the guide rail 1 to detect whether the guide rail 1 is level, ensuring measurement accuracy.

[0043] The method of using this utility model is as follows:

[0044] When using this device to measure hydraulic ring geological fractures, first adjust the length of the telescopic support legs according to the measurement environment to ensure the guide rail 1 is horizontal. This process can be checked and calibrated using a bubble level 15. Then, place the guide rail 1 above the fracture and move the first slider 5 and the second slider 6 so that the lasers emitted by the lasers on the first slider 5 and the second slider 6 are aligned with the two edges of the fracture, respectively. Next, tighten the fastening screws 12 to fix the slider positions and improve measurement stability. Ensure the measuring tape 2 is taut. At this time, the pointer 11 on the second slider 6 will point to the corresponding scale on the measuring tape 2. Reading this scale value will give the width of the fracture. If necessary, with the first slider 5 fixed to the guide rail 1, tighten one end of the measuring tape 2 by rotating and turning the handle 4.

[0045] The portable hydrogeological crack measuring device of this embodiment has a simple structure and is easy to operate. It can quickly and accurately measure the crack width and is suitable for on-site measurement of various hydrogeological cracks. It has high practicality and portability.
