Technical Field

[0002] Geological fracture measurement is a crucial step in engineering geological exploration, primarily used to assess the stability, integrity, and potential safety hazards of rock masses or concrete structures. By measuring parameters such as fracture width, depth, and orientation, a scientific basis can be provided for engineering design and construction. Traditional methods for measuring geological fractures typically rely on manual observation and simple tools such as rulers and calipers, but these methods have significant limitations.

[0003] Measuring the depth of geological fissures typically requires marking lines on-site with a ruler, a cumbersome process with limited accuracy. Furthermore, the need to hold the transducer probe and positioning tool with both hands not only increases the difficulty but also increases the risk of measurement errors due to human factors. Especially in complex terrain or confined spaces, traditional methods struggle to achieve rapid and accurate measurements. Utility Model Content

The guide rods are slidably connected to symmetrically distributed spacer plates, and a first spring is arranged on the inner wall of the spacer plate, with a positioning ball arranged on the outer wall of one end of the first spring.

[0007] The top outer wall of the spacer plate has a through-hole for installation, and a sleeve is fixedly connected to the inner wall of the installation hole by screws. A transducer probe is slidably connected to the inner wall of the sleeve, and a second spring is fixedly connected between the sleeve and the transducer probe.

[0008] Preferably, the sleeve is located between the two guide rods, and a limiting ring is provided on the outer wall of the transducer probe, with the limiting ring located at the bottom of the sleeve.

[0009] Preferably, a groove is provided on one outer wall of each of the two guide rods, and the positioning ball is in close contact with the inner wall of the groove.

[0010] Preferably, both ends of the guide rod are screwed with fastening knobs on their outer walls, and the fastening knobs are disposed through the outer wall of the side plate.

A display screen is provided on the top outer wall of the motherboard, and the transducer probe and the display screen are connected by a signal line.

[0012] Preferably, a positioning plate is fixedly connected to the center of the outer wall of the guide rod, and a handle is welded to the outer wall of one end of the positioning plate, and an observation port is opened on the top outer wall of the positioning plate.

[0013] The beneficial effects of this utility model are as follows:

[0014] 1.

[0022] Reference Figures 1-4 Example 1: A portable engineering geological crack measuring device includes a main board 1. Side plates 2 are installed at both ends of one outer wall of the main board 1, and adjacent guide rods 3 with scales are arranged between the two side plates 2. The guide rods 3 are slidably connected to the outer walls of the guide rods 3. A first spring 5 is provided on the inner wall of the guide rods 3, and a positioning ball 6 is provided on the outer wall of one end of the first spring 5. Grooves 10 are opened on one outer wall of the two guide rods 3, and the positioning ball 6 is tightly attached to the inner wall of the groove 10.

[0023] The mainboard 1 serves as the core supporting component of the device, with side plates 2 fixedly connected to both sides by screws. The guide rod 3 is fixed through the mounting holes of the side plates 2, facilitating disassembly and assembly.

[0024] In this embodiment, the sliding connection structure of the guide rod 3 and the spacer plate 4 enables rapid positioning and measurement of the crack width. The first spring 5 ensures that the positioning ball 6 and the groove 10 fit tightly together. By cooperating with the groove 10 of the guide rod 3, the positioning ball 6 on the spacer plate 4 can automatically lock the position during the measurement process, avoiding the tedious operation of traditional ruler marking positioning.

[0025] In embodiment 2, the top outer wall of the spacer plate 4 has a through-hole for installation, and a sleeve 7 is fixedly connected to the inner wall of the installation hole by screws. A transducer probe 8 is slidably connected to the inner wall of the sleeve 7, and a second spring 9 is fixedly connected between the sleeve 7 and the transducer probe 8. The sleeve 7 is located between two guide rods 3, and a limit ring 11 is provided on the outer wall of the transducer probe 8. The limit ring 11 is located at the bottom of the sleeve 7.

[0026] The guide rod 3 has grooves 10 evenly distributed on its surface, and the spacer plate 4 moves freely on the guide rod 3 via a sliding connection. The combination design of the first spring 5 and the positioning ball 6 allows the spacer plate 4 to automatically engage with the grooves 10 during movement, achieving rapid positioning.

[0027] In this embodiment, the transducer probe 8 can be controlled to be in close contact with the surface to be measured by the sliding connection between the transducer probe 8 and the sleeve 7 and the buffering effect of the second spring 9, thus realizing the accurate measurement of the crack depth. At the same time, the design of the handle 17 and the observation port 18 makes the device easy to operate in complex environments, significantly improving work efficiency.

[0028] Both ends of the guide rod 3 are screwed with fastening knobs 12, and the fastening knobs 12 are installed through the outer wall of the side plate 2.

[0031] The sleeve 7 is fixed in the mounting port of the spacer plate 4 by screws. The transducer probe 8 is inserted into the sleeve 7 and elastically connected by the second spring 9. The limiting ring 11 is located at the bottom of the sleeve 7 and is used to limit the transducer probe 8. The connector 13 and the signal line 14 transmit the data collected by the probe to the display screen 15 in real time to realize the visualization of the data.

[0032] A positioning plate 16 is fixedly connected to the center of the outer wall of the guide rod 3, and a handle 17 is welded to the outer wall of one end of the positioning plate 16. An observation port 18 is opened on the top outer wall of the positioning plate 16.

[0033] The positioning plate 16 is installed at the center of the guide rod 3, and the handle 17 is ergonomically designed for easy one-handed operation. The observation port 18 is located on the top of the positioning plate 16, allowing users to view the measurement status in real time, further improving the ease of operation.

[0034] Working principle:

[0035] Width measurement: Place the transducer probe 8 on both sides of the crack, slide the spacer plate 4, and let the positioning ball 6 be inserted into the groove 10 of the guide rod 3 by the action of the first spring 5. The positioning can be achieved by observing the scale on the guide rod 3.

[0036] Depth measurement: Press down the grip 17 so that the transducer probe 8 is pressed against the surface of the object to be measured under the buffering action of the second spring 9. The transducer probe 8 transmits the depth data to the display screen 15 through the signal line 14 to display the measurement result in real time.

[0037] Data recording: The display screen 15 integrates data storage function, which can record multiple measurement results for easy subsequent analysis. The design of the handle 17 and the observation port 18 enables the device to operate efficiently in complex environments.
