Embodiment 1

[0048] A sound wave detection device for wall percussion, such as figure 1 As shown, it includes a vehicle body 1, a percussion unit 2, a sensor unit 3, and a controller (not shown), wherein: the vehicle body 1 is used to move on the wall; the percussion unit is arranged on the vehicle body 1, including a drive connected in turn Drive assembly, elastic action assembly and percussion block. The drive assembly acts on the elastic action assembly by rotating and drives the action of the elastic action assembly, so that the percussion block strikes the wall once and bounces within a working cycle; sensor unit 3 It is set on the body 1 and includes a sound wave sensor and a sensor lifting assembly. The sensor lifting assembly drives the sound wave sensor down to fit the wall before the knocking block hits the wall, and drives the sound wave sensor to reset after the knock is completed; To control the actions of the percussion unit and the sensor unit.

[0049] In this embodiment, such...

Embodiment 2

[0059] Such as Picture 10 with Picture 12 As shown, the wall tap sound wave detection device of this embodiment includes a vehicle body 1, a tap unit 4, a sensor unit 3, and an electronic control module.

[0060] The vehicle body 1, the percussion unit 4, the sensor unit 3 and the electronic control module of this embodiment are basically the same as those of the first embodiment. the difference lies in:

[0061] In this embodiment, the drive assembly includes a shift lever right angle motor 4032 and a dial shift lever mechanism. The dial shift lever mechanism consists of a dial A4035 connected to the shaft of the shift lever right angle motor 4032 and a multiplicity evenly distributed along the circumference of the dial A4035. Consists of two shift rods 4038 (in this embodiment, there are four shift rods 4038, and the corresponding center angles of two adjacent shift rods 4038 are 90°)

[0062] In this embodiment, the knock block is a knock block B4016.

[0063] In this embodiment...

Embodiment 3

[0071] Such as Figure 16 As shown, the wall knock sound wave detection device of this embodiment includes a vehicle body 1, a knock unit 5, a sensor unit 3, and an electronic control module.

[0072] The body 1, the percussion unit 5, the sensor unit 3, and the electronic control module of this embodiment are basically the same as those of the first embodiment. the difference lies in:

[0073] In this embodiment, the drive assembly includes a shift block right-angle motor A503 and a dial shift block mechanism. The dial block mechanism consists of a dial B502 connected to the shaft of the shift block right-angle motor A503 and a plurality of dials evenly distributed along the circumference of the dial B502. It is composed of two dial blocks A501 (in this embodiment, there are four dial blocks A501, and the center angles corresponding to two adjacent dial blocks A501 are 90°).

[0074] The knock block in this embodiment is a knock block C507.

[0075] The elastic action component in t...

Abstract

The invention relates to a metope percussion sound wave detecting device, comprising a vehicle body, a tapping unit, a sensor unit and a controller, wherein the tapping unit is arranged on the vehiclebody, and comprises a driving component, an elastic motion component and a tapping block connected in sequence.The driving component acts on the elastic motion component by rotating, and drives the elastic motion component to move, so that the tapping block strikes the metope and bounces in a working cycle. The sensor unit is arranged on the vehicle body, and includes a sound wave sensor and a sensor lifting assembly. The sensor lifting assembly drives the sound wave sensor to fall to the metope before the tapping block hits the metope, and drives the sound wave sensor to reset after the tapping is completed. Compared with the prior technology, the invention drives the elastic action component by the motor and drives the tapping block to strike the metope, and each tapping force is fixedand adjustable, and the sound wave sensor is closely attached to the wall to collect and detect sound waves, so that the detection is reliable and accurate.

Description

Technical field [0001] The invention relates to the field of wall detection, in particular to a sound wave detection device for wall knocking. Background technique [0002] The hollowing of the exterior wall of buildings is a common problem, and how to detect the hollowing of the exterior walls of existing buildings is getting more and more attention. On the basis of in-depth analysis of traditional percussion detection methods, experiments have been carried out under different exterior wall finishes and various working conditions. The results show that the sound and vibration characteristics of wall percussion can be used to determine the hollowness of the wall. Facing bricks, mosaics or stucco plastering are often used to protect the exterior walls of buildings, and they have beautiful effects. However, due to factors such as unqualified materials in construction projects, improper construction techniques or unqualified construction quality, and natural aging during normal use...
