[0022] In this implementation:

[0023] Furthermore, a liquid extraction pipe 21 is installed at the input end of the liquid extraction pump 22, and a hose 12 is installed at the output end of the liquid extraction pump 22. The hose 12 passes through the liquid storage tank 20, and the end of the hose 12 away from the liquid storage tank 20 is connected to the nozzle 14. The liquid extraction pump 22 extracts the paint inside the liquid storage tank 20 through the liquid extraction pipe 21, and can draw the paint into the nozzle 14 through the hose 12.

[0024] Furthermore, a first bearing 2 is installed at one end of the mounting bin 1 near the control panel 3, and a rotating rod 23 is installed inside the first bearing 2. Two groups of first bevel gears 19 meshing with second bevel gears 24 are installed on the outer side of the rotating rod 23. When in use, the rotating rod 23 is rotated so that the rotating rod 23 drives the two groups of second bevel gears 24 to rotate through the two groups of first bevel gears 19, thereby driving the two groups of threaded rods 7 to rotate, and the height of the mounting plate 8 can be directly adjusted. The adjustment process is relatively convenient to operate, and the device is relatively convenient to use.

[0025] Furthermore, a T-shaped plate 15 is installed at one end of the sliding plate 13 close to the motor 16, and a ball groove 28 is provided at one end of the T-shaped plate 15 away from the sliding plate 13. A ball 29 is installed inside the ball groove 28. The ball 29 is in contact with the special-shaped protrusion 17. When the special-shaped protrusion 17 rotates, the ball 29 can rotate with the special-shaped protrusion 17 without affecting the rotation of the special-shaped protrusion 17.

[0026] Furthermore, a fixing plate 9 is installed at one end of the bottom of the mounting plate 8 away from the motor 16, and a return spring 10 is installed at one end of the fixing plate 9 close to the motor 16. The end of the return spring 10 away from the fixing plate 9 is connected to the sliding plate 13. When the protrusion 18 on the special-shaped protrusion 17 rotates to a position away from the ball 29, the special-shaped protrusion 17 no longer squeezes the ball 29. At this time, the elastic action of the return spring 10 causes it to push the sliding plate 13 to move and reset. The sliding plate 13 drives the nozzle 14 to move together, so that the position of the nozzle 14 can be adjusted.

[0027] Furthermore, second sliding components 25 are installed at both ends inside the mounting tube 5, and guide sliders 26 are slidably installed on the inner side of the second sliding components 25. The ends of the guide sliders 26 away from the second sliding components 25 are connected to the threaded tube 6. The threaded tube 6 is limited by the guide sliders 26 to prevent the threaded tube 6 from rotating with the threaded rod 7.

[0028] Furthermore, the rotating rod 23 passes through the installation bin 1 and extends to the outside of the installation bin 1 , and a handle is installed at one end of the rotating rod 23 away from the first bearing 2 to facilitate the staff to rotate the rotating rod 23 .

[0029] Working principle:

[0030] When in use, first move the device to the position of the inner wall of the civil air defense project, and then add a proper amount of paint into the liquid storage tank 20;

[0031] The staff can first rotate the rotating rod 23 clockwise or counterclockwise, and the rotating rod 23 drives the two sets of second bevel gears 24 to rotate through the two sets of first bevel gears 19, which can drive the two sets of threaded rods 7 to rotate. The threaded tubes 6 outside the two sets of threaded rods 7 are limited by the guide sliders 26, so that the threaded tubes 6 cannot rotate with the threaded rods 7, so that the two sets of threaded tubes 6 can only move upward or downward at the same time through the threads;

[0032] At this time, the threaded tube 6 drives the guide slider 26 to slide along a straight line on the second sliding assembly 25, and the threaded tube 6 drives the mounting plate 8 to move through the support rod 30, thereby driving the spray head 14 to move, and the spray head 14 can be raised and lowered to a specified height position of the inner wall for spraying;

[0033] During spraying, the staff can start the liquid pump 22 through the control panel 3, so that the liquid pump 22 draws the paint inside the liquid storage tank 20 into the inside of the spray head 14, and sprays it evenly through the spray head 14, so that the paint can be sprayed onto the inner wall of the civil air defense project;

[0034] During the spraying process, the staff can start the motor 16 through the control panel 3, so that the motor 16 drives the special-shaped protrusion 17 to rotate at a constant speed through the rotating shaft 27;

[0035] When the protrusion 18 on the special-shaped protrusion 17 rotates to contact the ball 29, the special-shaped protrusion 17 squeezes the ball 29, so that the T-shaped plate 15 is subjected to force and pushes the sliding plate 13 to move. At this time, the sliding plate 13 squeezes the return spring 10, and the sliding plate 13 drives the nozzle 14 to move together, so that the position of the nozzle 14 can be adjusted;

[0036] When the protrusion 18 on the special-shaped protrusion 17 rotates to a position away from the ball 29, the special-shaped protrusion 17 no longer squeezes the ball 29. At this time, the elastic action of the return spring 10 causes it to push the sliding plate 13 to move and reset, and the sliding plate 13 drives the nozzle 14 to move together, so that the position of the nozzle 14 can be adjusted;

[0037] Since the motor 16 drives the special-shaped protrusion 17 to rotate at a constant speed through the rotating shaft 27, the protrusion 18 on the special-shaped protrusion 17 can repeatedly squeeze the ball 29, which can drive the spray head 14 to move back and forth, so that the spray head 14 can repeatedly spray the local area of ​​the inner wall, thereby effectively improving the spraying effect and spraying efficiency.

[0038] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention.
