Description

Technical Field

[0001] The present application relates to the field of detection technology, and in particular to a wall thickness detection device. Background Art

[0002] Brick wall perimeter is a perimeter built with bricks and concrete. When used in certain places, its thickness needs to meet the relevant standard requirements. For example, the Civil Transport Airport Security Facilities (MHT 7003-2017) stipulates that the thickness of the brick wall perimeter used in the airport "shall not be less than 240mm", which requires that its thickness be tested after the brick wall perimeter is completed.

[0003] When testing the thickness of the enclosure, it is often necessary to sample and test multiple locations. Since the enclosure is generally high, as stipulated in the Civil Transport Airport Security Facilities (MHT 7003-2017), "the net height of the inner and outer sides of the physical enclosure should not be less than 2.5m", it is inefficient to climb to the top of the enclosure with a ladder every time for multiple sampling. In addition, some brick wall enclosures have a masonry top surface on the top, and the cross-sectional width of the masonry top surface is greater than the cross-sectional width of the main body of the brick wall enclosure, which makes it impossible to detect with conventional detection devices such as calipers or rulers.

[0012] In order to make the technical solutions and advantages of the present disclosure more clearly understood, the present disclosure is further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0013] Figure 1 FIG. 1 is a schematic diagram showing a structure of an embodiment of a wall thickness detection device disclosed in the present invention. Figure 1 As shown, the wall thickness detection device of this embodiment may include: a support rod 11, a laser distance sensor 12, a light reflection plate 13, a calculation component 14 and a digital display component 15.

[0014] The support rod 11 includes a first sub-rod 111, a second sub-rod 112 and a third sub-rod 113. The first sub-rod 111 is parallel to the third sub-rod 113, the second sub-rod 112 connects the first sub-rod 111 and the third sub-rod 113, and the first sub-rod 111 and the third sub-rod 113 are arranged on both sides of the measured wall. In some specific practices, the first sub-rod 111 and the third sub-rod 113 can be straight rods, and the second sub-rod 112 can be a straight rod or a curved rod. The first sub-rod 111, the second sub-rod 112 and the third sub-rod 113 can be fixedly connected or detachably connected to facilitate storage.

[0015] The laser distance sensor 12 may include a first laser distance sensor 121 and a second laser distance sensor 122, and the light reflection plate 13 includes a first light reflection plate 131 and a second light reflection plate 132. The first laser distance sensor 121 and the first light reflection plate 131 are arranged on the first sub-pole 211, and the second laser distance sensor 122 and the second light reflection plate 132 are arranged on the third sub-pole 213. The laser emitted by the first laser distance sensor 121 is vertically reflected by the second light reflection plate 132, and the laser emitted by the second laser distance sensor 122 is vertically reflected by the first light reflection plate 131. That is, the first laser distance sensor 121 is directly opposite to the second light reflection plate 132, and the second laser distance sensor 122 is directly opposite to the first light reflection plate 131. If the first laser distance sensor 121 and the second laser distance sensor 122 are arranged on different horizontal planes, the second light reflection plate 132 and the first light reflection plate 131 are also arranged on different horizontal planes.

[0016] The laser distance measuring sensor 12 and the light reflecting plate 13 can be fixed on the support rod in various ways, for example, by bolts, or by straps, etc.

[0017] The calculation component 14 can be connected to the first laser ranging sensor 121 and the second laser ranging sensor 122, and is used to receive the values ​​output by the first laser ranging sensor 121 and the second laser ranging sensor 122, and determine the thickness of the measured wall according to the above values.

Similarly, the calculation component 14 can read the second value output by the second laser ranging sensor 122, and the second value is used as the distance between the second laser ranging sensor 122 and the side of the measured wall close to the second laser ranging sensor 122. Then, the difference between the first laser ranging sensor 121 and the second laser ranging sensor 122 is subtracted from the first value and the second value, and the difference is the thickness of the measured wall. In this embodiment, the calculation component 14 can be implemented by a chip, such as an FPGA chip.

[0018] The digital display component 15 may be connected to the calculation component 14 to display the thickness value calculated by the calculation component 14. Here, the digital display component may be any display capable of displaying numerical values.

The second laser ranging sensor 222 and the second light reflecting plate 232 are horizontally arranged on the first cross bar 2111, that is, the heights of the two are consistent.

Here, the support component 2112 may be a folded structure, a part of which contacts the first sub-rod 211, and another part of which contacts the surface of the measured wall, so that the first sub-rod 211 is parallel to the surface of the measured wall.

Similarly, the battery is also placed in the internal space of the first sub-rod in advance, so that after the connecting wire is connected, the battery can power the two laser ranging sensors, the computing component, and the digital display component. Then, the computing component can read the output data of the two laser ranging sensors respectively, and record them as , Here, , are the distances between the two laser distance measuring sensors and the opposite light reflecting plates. , The average value is recorded as the initial thickness . Then, the U-shaped opening of the wall thickness detection device of the present invention is passed through the top of the brick wall boundary or the masonry pressure top surface, so that the two laser distance sensors are located on both sides of the measured wall. And the two support columns of the support component are close to one side of the measured wall, so as to ensure that the wall thickness detection device remains stable and the ranging beam of the laser distance sensor is perpendicular to the surface of the measured wall, thereby reducing the measurement error. Finally, the calculation component can read the two values ​​of the two laser distance sensors, which are recorded as , The final thickness of the measured wall is .
