Example Embodiment

[0023] Example

[0024] refer to Figure 1 to Figure 4 As shown, the present invention discloses an engineering crack sensor, comprising a base 10, a first groove 14 is provided on the base 10, a vernier scale is arranged in the first groove body 14, the vernier scale includes a main scale and a vernier, and the main scale is fixed Set on the base 10, the vernier is set on the main scale and can slide along the main scale. The main ruler and vernier used in the present embodiment are the same as the vernier caliper, and the vernier is sleeved on the main ruler.

[0025] A guide hole is provided on the base 10 , and a first guide rod 21 is arranged in the guide hole. One end of the first guide rod 21 is connected with the vernier, and the other end of the first guide rod 21 protrudes outward from the base 10 . The direction where the guide hole is located is on the same straight line as the moving direction of the cursor. Then the movement of the first guide rod 21 along the...

Abstract

The invention discloses an engineering crack sensor. The engineering crack sensor comprises a base, wherein a first slot is formed in the base; a vernier scale is arranged inside the first slot; the vernier scale comprises a main scale and a vernier; the main scale is fixedly arranged on the base; the vernier is arranged on the main scale and can slide along the main scale; a guide hole is formedin the base; a first guide rod is arranged inside the guide hole; one end of the first guide rod is connected with the vernier; the other end of the first guide rod stretches out from the base; an image acquisition assembly is arranged on the upper side of the vernier scale; the image acquisition assembly comprises a lens sleeve, a light source, frosted glass and a camera; a central hole is formedin the center of the lens sleeve; the camera is arranged inside the central hole; the camera is downwardly arranged; a second slot is formed in the lower surface of the lens sleeve; the second slot is arranged around the central hole; the light source is arranged inside the second slot; the frosted glass is arranged at an opening of the second slot. The engineering crack sensor can monitor cracks, has high detection accuracy, improves the detection efficiency and reduces safety hazards.

Description

technical field [0001] The invention relates to the technical field of civil engineering measurement, in particular to an engineering crack sensor. Background technique [0002] For engineering buildings, after a certain period of time, cracks will appear on some walls. Slight cracks will not affect the use of buildings such as buildings. However, the longer the time, the cracks may become larger and larger. At this time, excessive cracks There will be safety hazards. Therefore, it is necessary to monitor the crack size of the wall to eliminate potential safety hazards. [0003] For cracks on the wall, usually the staff uses a ruler to measure the size of the crack. However, since this kind of wall with cracks needs regular maintenance, the staff need to manually measure the cracks, which is time-consuming and labor-intensive, and some cracks are located in a relatively high location, and the staff need to climb up and down, which is extremely inconvenient to work, and the...
