[0027] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but cannot be understood as limiting the present invention.

[0028] The underground tunnel painting device of the utility model embodiment is described below in conjunction with the accompanying drawings.

[0029] like Figures 1 to 5 As shown, the underground tunnel paint spraying device of the embodiment of the utility model includes: a paint spraying tank 1, an air intake component 2 and a paint spraying component 3.

[0030] Among them, Figure 3 As shown, the paint tank 1 has a U-shaped cavity arranged in the up-down direction. The U-shaped cavity includes a first vertical section, a second vertical section and an arc-shaped connecting section, and the lower end of the first vertical section is connected to the lower end of the second vertical section through the arc-shaped connecting section. The upper part of the paint tank 1 is provided with an air inlet 101 and a paint outlet 102, the air inlet 101 is connected to the upper end of the first vertical section, and the paint outlet 102 is connected to the upper end of the second vertical section.

[0031] like Figure 4 As shown, the air intake component 2 has an air intake end and an air delivery end. The air intake end is connected to the compressed air pipe in the alley, and the air delivery end is connected to the air intake hole 101, so as to inflate the paint storage tank 1. No power source is needed, and the paint in the U-shaped cavity of the paint storage tank 1 is discharged through the paint outlet hole 102 by air pressure.

[0032] like Figure 5 As shown, the input end of the paint spraying assembly 3 is connected to the paint outlet hole 102, and the paint spraying assembly 3 has a nozzle for spraying paint, so that the paint in the paint spraying tank 1 is sprayed out through the nozzle, thereby spraying paint on the pipeline or wall in the lane.

[0033] Therefore, the underground tunnel painting device of the embodiment of the utility model does not require power supply and uses air pressure to spray paint on the pipes or walls in the tunnel, thereby improving the efficiency and effect of the painting operation, avoiding the risks of high-altitude painting operations, and reducing the labor cost of tunnel lighting work.

[0034] In some embodiments, Figure 3 As shown, a paint discharge hole 103 is provided at the bottom of the paint spray tank 1, and the paint discharge hole 103 is connected to the arc-shaped connecting section.

[0035] It is understandable that in order to facilitate the cleaning of the paint tank 1, a paint drain hole 103 is opened at the bottom of the paint tank 1 so that after the painting operation is completed, the paint in the paint tank 1 can be discharged through the paint drain hole 103, which is more convenient than turning over the paint tank 1 and pouring out the paint.

[0036] For example, after the painting operation is completed, the air inlet end of the air inlet component 2 and the compressed air pipe in the tunnel are removed, and then the air pressure in the paint tank 1 is released through the air inlet end of the air inlet component 2, and finally the paint in the paint tank 1 is unloaded through the paint discharge hole 103.

[0037] Specifically, Figure 3 As shown, the arc-shaped opening of the arc-shaped connecting section faces upward, and the connection between the paint discharge hole 103 and the arc-shaped connecting section is located at the bottom end of the arc-shaped connecting section, thereby improving the discharge effect.

[0041] The cover 14 is circular and matches the can 12. The cover 14 is arranged at the upper end of the can 12. The cover 14 and the base 11 together seal the can 12, thereby improving the safety of the paint storage tank 1. The air inlet 101 and the paint outlet 102 are both arranged on the cover 14, and the air inlet 101 and the paint outlet 102 are spaced apart along the radial direction of the cover 14.

[0044] Alternatively, if Figure 3 As shown, the cross-sectional areas of the air inlet connector 16 and the paint outlet connector 17 gradually increase from top to bottom, so as to facilitate connection while ensuring the storage space of the paint tank 1 .

[0045] In some embodiments, Figure 4 As shown, the air intake assembly 2 includes a flange joint 21, a first quick joint 22 and an air supply pipeline 23 connecting the flange joint 21 and the first quick joint 22.
