Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments; based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0020] like Figures 1 to 3 As shown, a hollow detection structure for construction project quality inspection includes a telescopic rod 1 and a hammer head 2 installed on the top of the telescopic rod 1. A cylinder 3 is movably installed on the end of the telescopic rod 1, and a threaded cylinder 9 is fixedly connected to the bottom of the cylinder 3. The top of the telescopic rod 1 is provided with a thread and is threadedly connected to the threaded cylinder 9. A mounting plate 4 is movably installed inside the cylinder 3, and a plurality of positioning columns 10 are fixedly connected to the inner bottom surface of the cylinder 3. The mounting plate 4 is installed on the positioning columns 10 by screws. A positioning seat 5 for installing the hammer head 2 is fixedly connected to the front end face of the mounting plate 4, and a threaded hole is opened in the middle of the positioning seat 5. A connecting rod 11 is fixed to one side of the hammer head 2, and the end of the connecting rod 11 is provided with a thread and is threadedly connected to the positioning seat 5.

[0021] The cylinder 3 is installed on the top of the telescopic rod 1 through the threaded cylinder 9, and the hammer head 2 is installed on the positioning seat 5 through the connecting rod 11, so that the connection between the hammer head 2 and the telescopic rod 1 is realized.

[0022] like Figure 3 and Figure 4 As shown, the front end face of the mounting plate 4 is movably provided with an annular groove 6 outside the positioning seat 5, the front end of the annular groove 6 is connected to a flexible protective cover 7, an ink storage pad 8 extending to the outside of the annular groove 6 is installed inside, a plurality of through holes are provided on the front end face of the protective cover 7, the ink storage pad 8 is a polyurethane foam pad, an ink replenishing port is provided on the side of the annular groove 6, a sealing plug 12 is installed at the ink replenishing port, and a driving component for driving the annular groove 6 to move is installed on the cylinder 3.

[0023] Ink is added to the annular groove 6 through the ink filling port, and the ink storage pad 8 stores the ink. When the flexible protective cover 7 is squeezed, the ink storage pad 8 is compressed and deformed and releases the ink. The ink passes through the through holes on the surface of the protective cover 7 and is printed on the wall to achieve marking.

[0024] like Figure 2 and Figure 3As shown, the drive assembly includes a movable plate 13 arranged at the rear end of the cylinder 3, and a plurality of cross bars 14 are fixedly connected to the front end of the movable plate 13. The front end of the cross bar 14 passes through the rear end face of the cylinder 3 and the mounting plate 4 and is connected to the annular groove 6. A spring 15 is provided on the outside of the cross bar 14 between the movable plate 13 and the cylinder 3. The drive assembly also includes a DC motor 16 installed inside the cylinder 3. A winding wheel 17 is installed on the output shaft of the DC motor 16. A pull rope 18 is wound on the winding wheel 17. One end of the pull rope 18 passes through the rear end face of the cylinder 3 and is connected to the movable plate 13.

[0025] When the DC motor 16 drives the reel 17 to rotate and reel the rope 18, the movable plate 13 moves toward the cylinder 3, prompting the crossbar 14 to push the annular groove 6 forward. At the same time, the spring 15 is compressed, allowing the marking operation to proceed. After marking is completed, the DC motor 16 drives the reel 17 to rotate and reel the rope 18. Under the action of the spring 15, the annular groove 6 retracts into the interior of the cylinder 3.

[0026] A battery and a controller are also installed inside the cylinder. A handle is provided at the bottom of the telescopic rod, and a remote control device is built into the handle. Control buttons of the remote control device are provided on the surface, and the controller has a built-in wireless communication module for communicating with the remote control device.

[0027] In specific use, hollowing detection is achieved by knocking the wall with the hammer head 2. When hollowing is detected, the hammer head 2 is located at the hollow position, and the DC motor 16 drives the winding wheel 17 to rotate to reel in the pull rope 18, prompting the cross bar 14 to push the annular groove 6 forward, and pressing the protective cover 7 against the wall. The ink storage pad 8 is compressed and deformed and releases ink, and the ink passes through the through holes on the surface of the protective cover 7 and is printed on the wall, thereby achieving quick and accurate marking of the hollow position.
