[0002] During the shipbuilding process, it is often necessary to paint some narrow and enclosed compartments. For narrow compartments with manholes, usually, workers enter the interior of the compartment through the manhole for painting. However, it is inconvenient for workers to operate in a narrow space, and it is difficult to paint with poor results. At the same time, when painting in a closed space, the air lacks circulation, and the internal air quickly deteriorates, seriously affecting the physical health of workers and posing a safety hazard.

[0041] As Figure 4, as shown in FIGS. 5 and 7, the control assembly includes a first wireless control motor 31, a second wireless control motor 32, a third wireless control motor 33, and a fourth wireless control motor 34.

[0042] Furthermore, the structural connection relationship and functions of the paint spraying assembly 1 in this embodiment will be described in detail.

[0043] As Figure 9 shown, first of all, the fixed base at the uppermost end of the paint spraying assembly needs to be connected to the adapter plate 20 at the lowermost end of the support assembly: the upper part of the fixed base 18 is provided with a linear buckle 18a, and the lower part of the adapter plate 20 is provided with a linear inlet 20d and a linear card slot 20e. The linear inlet 20d and the linear card slot 20e are designed in a "cross" shape. The linear buckle 18a on the upper part of the fixed base 18 is inserted into the linear inlet 20d below the adapter plate 20 and is snapped into the linear card slot 20e after rotating a certain angle, so that the fixed base 18 is fixedly connected to the adapter plate 20 at the end of the support assembly 2.

[0044] Secondly, the fixed base 18 is connected to the rotating disk 17: the second wireless control motor 32 is installed inside the fixed base 18, and a rotating disk connection hole 17a is opened in the upper part of the rotating disk 17. The rotating disk 17 is driven to rotate by the second wireless control motor 32 by means of threaded connection or the like.

[0045] Then, the rotating disk 17 is connected to the foldable robotic arm 16: as Figure 4 、 9As shown in the figure, the foldable robotic arm 16 includes a first robotic arm 16b, a second robotic arm 16c, and a third robotic arm 16d that are sequentially foldably connected. A conduit hole 16a is provided on the side wall of the second robotic arm 16c. The first spraying hose 12 is fixedly connected to the foldable robotic arm 16 through the conduit hole 16a. A rotary disk connection groove 17b is provided below the rotary disk 17. The first robotic arm 16b is connected to the rotary disk connection groove 17b of the rotary disk 17 by means of a hinge or the like, so that the foldable robotic arm 16 is connected to the rotary disk 17, and the first robotic arm 16b is driven by the first wireless control motor 31 to move along a certain coordinate axis direction by a corresponding safe angle. Among them, the second robotic arm 16c, the third robotic arm 16d, and the nozzle 11 are sequentially connected in the same manner and perform safe rotational movements in the same coordinate axis direction.

[0048] Furthermore, the structural connection relationship and functions of the monitoring component 1A in this embodiment are described in detail.

[0049] Since the narrow cabin has strong airtightness, the distribution of light is less and uneven. When automatically spraying the inner surface of the narrow cabin, it is necessary to obtain the spraying state. Therefore, it is necessary to introduce the monitoring component 1A to monitor the spraying situation inside the cabin. As Figure 2, as shown in Figure 4, first, the camera 1A1 is fixedly connected to the side of the rotating disk 17 in the painting assembly 1. The shooting direction of the camera 1A1 can be changed according to the direction of the foldable robotic arm 16. When the rotating disk 17 rotates, the camera 1A1 rotates in parallel with the foldable robotic arm 16. Secondly, the light sources 1A2 are evenly distributed and fixedly connected to the lower side of the rotating disk 17, with a total of four in the front, back, left, and right directions. Finally, a communication connection is established between the camera 1A1 and the display control system 1A3.

[0053] Finally, place the support platform cover 29 on the support platform: As Figure 3 shown in Fig. 7, a lubrication hole 29a is provided on the support platform cover 29, and lubricating oil can flow in through this place to lubricate the gear 27.

[0054] In addition, as Figure 3 shown in the figure, connect the first movable support rod 23 and the second movable support rod 24 together by means of movable connection such as hinges, which plays roles such as bearing and stabilizing the rack cylinder.

[0055] Furthermore, the structural connection relationship and functions of the anti-blocking component 2A in this embodiment will be described in detail.
