Description

Technical Field

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

[0002] Methods for detecting wall cavities primarily include percussion, electric drilling, observation, and tapping with a small hammer. The percussion method involves tapping the wall and listening to the sound to determine if there are any hollows. Use your hand or a wooden tool to tap the wall. A dull sound indicates a tight wall, while a crisp sound may indicate a hollow. This method is simple and easy, but requires a certain level of auditory judgment. The electric drill method involves drilling a hole in the wall. If you feel a sudden decrease in resistance, you've likely encountered a hollow area. Use a ruler or other tool to measure the depth of the hole to confirm whether there is a hollow. This method requires caution to avoid causing unnecessary damage to the wall. The observation method involves observing the wall from a distance, noting the location of any hollows, and then feeling them to determine their location and size. This method is suitable for detecting hollows in painted and tiled surfaces. The small hammer tap method involves tapping the wall with a small hammer or screwdriver to listen for a hollow sound. A hollow sound indicates a hollow area that requires repair. This method focuses on checking the corners and joints of the wall and places where water and electricity have been modified.

[0003] The existing method of detecting wall cavities mainly involves knocking on the wall to determine whether a cavity exists. Most of the operations are manual. However, cavities need to be detected at various locations on the wall, and the operator needs to knock continuously, which is labor-intensive and not convenient for more labor-saving detection.

The knocking component 3 also includes an elastic piece 307. The material of the elastic piece 307 is metal and has a certain elasticity. The elastic piece 307 is fixedly connected to the left side of the support ring 1, and the elastic piece 307 is movably fitted with the right side of the swing arm 302. The left side of the toggle block 305 is rotatably connected to a support frame 308, and the shape of the support frame 308 is L-shaped. The support frame 308 is fixedly connected to the left side of the support ring 1, and the inner surface of the support ring 1 is rotatably connected to the rotating ring 4. An annular slide groove is provided between the rotating ring 4 and the support ring 1 for rotation.

[0022] When the above-mentioned device is used, the support ring 1 is first attached to the wall to be inspected through the handle 2, and then the dual-axis motor 304 is started.
