Technical Field

[0001] This utility model relates to the technical field of construction site monitoring tools, and in particular to a surface crack monitoring device. Background Technology

[0002] In the construction of mountain highway projects, there are a large number of high slopes and high embankments. Due to the relatively complex hydrological and geological conditions in mountainous areas, unstable situations such as displacement, deformation, cracking, and collapse are inevitable during the construction process. The risk factor is high and the construction is difficult.

[0003] The existing technology measures surface cracks by periodic measurements. This method is labor-intensive for workers and, because it monitors surface cracks periodically, it is impossible to measure the actual condition of the cracks, which poses a safety hazard.

[0004] Therefore, existing technologies for monitoring surface cracks present a technical problem: they cannot be monitored in real time. Utility Model Content

[0005] The present invention provides a surface crack monitoring device, which solves the technical problem that surface cracks cannot be monitored in real time in the prior art.

[0039] The specific embodiments shown below are intended to describe various configurations of the subject matter of this invention and are not intended to represent the only configuration in which the subject matter of this invention can be practiced. The specific embodiments include detailed descriptions intended to provide a thorough understanding of the subject matter of this invention. However, it will be clear and apparent to those skilled in the art that the subject matter of this invention is not limited to the specific details shown herein and can be practiced without these specific details.

[0040] Understandably, in this document, relational terms such as “first” and “second” are intended to distinguish one entity or operation from another, and are not intended to expressly or imply any actual relationship or order between these entities or operations.

[0041] The terms “comprising,” “including,” or any other variations thereof are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitation, an element defined by the phrase “comprising one…” does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.

[0042] Reference Figures 1 to 6 As shown, a surface crack monitoring device includes a first base 1;

[0043] The second base 2, the first base 1 and the second base 2 are respectively located on both sides of the surface crack;

[0044] Measurement component 3, one end of which is fixed to the first base 1, and the other end of which is fixed to the second base 2;

[0045] Magnetic break point alarm 11, the magnetic break point alarm is fixed to the first base 1;

[0046] And a rigid pull rope 4, one end of which is fixed to the second base 2, and the other end of which is fixed to the magnetic break alarm 11, which is triggered by the rigid pull rope 4;

[0047] The measuring component 3 includes a first measuring rod 31 fixed to the first base 1 and a second measuring rod 32 fixed to the second base 2, wherein the second measuring rod 32 supports the first measuring rod 31;

[0048] The second measuring rod 32 is slidably connected to the second base 2, and a height adjustment component 5 is provided between the second measuring rod 32 and the second base 2 to adjust the height of the second measuring rod 32 relative to the second base 2.

[0049] Understandably, the magnetic breakage alarm 11 can operate by triggering an alarm when the crack expands and breaks. The alarm can be triggered by automatically making a phone call or sending a message to a contact's mobile phone. The contact records the crack expansion data using calipers that have been pulled apart after the crack expands, thus analyzing the dynamics of crack deformation development.

[0050] In practice, a first base 1 and a second base 2 are respectively set on both sides of the crack. The magnetic break alarm 11 is fixed to the first base 1. Alternatively, it can be fixed to the second base 2. The magnet is pulled horizontally straight and fixed to the second base 2 using a rigid pull rope 4. Similarly, the measuring component 3 is fixed between the first base 1 and the second base 2.

[0051] The magnetic break point alarm 11 is an outdoor rainproof 4G fast alarm type. It is equipped with a mobile phone card and connected to a mobile terminal. The mobile terminal can be a portable electronic device, such as a smartphone. The break point sensitivity is 0.03 mm. The rigid pull rope 4 is a non-elastic rope. The first insert plate 12 of the first base 1 and the second insert plate 22 of the second base 2 are driven into the ground to a depth of 60-80 cm depending on the soil conditions (deeper for loose soil).

[0052] When the crack expands beyond 0.03mm, the magnetic break point alarm 11 disconnects, automatically dials the pre-set contact number, and sends an alarm message. Upon receiving the alarm message, the contact person arranges for someone to check the monitoring point and record the data measured by the measuring component 3. After recording, the magnetic break point alarm 11 is reset so that it can generate an early warning alarm for the next large deformation. This solution is technically feasible, easy to install, novel, and low-cost. Using magnetic break point alarms for simple geological disaster monitoring is a practical and cost-effective technology for monitoring surface cracks.

[0053] In some embodiments, the magnetic break point alarm 11 has a communication module, through which the magnetic break point alarm 11 sends alarm information. The communication module can be a 4G / 5G communication module, etc.

[0056] Surface crack monitoring devices are typically used outdoors, so the electronic components need to be protected from rain. The electronic components are protected from damage by being placed inside a rain cover.

One end of the support rod 52 is welded to the slide block 51, and the other end of the support rod 52 is welded to the second measuring rod 32.

[0058] The height adjustment component 5 allows the position of the first measuring rod 31 relative to the second measuring rod 32 in the height direction to be adjusted, thereby meeting different measurement needs. For example, when the ground on both sides of a surface crack is uneven, the height adjustment component 5 can compensate for the height difference between the two sides of the surface crack.

[0059] In some embodiments, the slide block 51 is further provided with a baffle 53, the first measuring rod 31 is located between the baffle 53 and the second measuring rod 32, the baffle 53 is welded to the slide block 51, and the first measuring rod 31 is provided with a rib 311 to improve the bending strength of the first measuring rod 31.
