Technical Field

[0001] This utility model relates to the field of fire safety, and in particular to a spraying mechanism and a fire-fighting robot. Background Technology

[0002] Currently, most robots that use gas as a medium employ fixed-value spray devices. With the acceleration of urbanization, the complexity and diversity of emergency events such as fires are constantly increasing. Traditional firefighting robots using fixed-value spray devices have limited spray coverage. For example, when a fire occurs at a high location or in a large space, fixed spray devices often require frequent adjustments to the robot's position to ensure that the extinguishing medium can cover the fire source. This not only reduces firefighting efficiency but may also delay the best time to extinguish the fire.

[0003] Therefore, it is necessary to design a mechanism that can adjust the angle and height to solve the above-mentioned defects of the fixed value spraying device. Utility Model Content

[0028] Reference Figures 1-2 This embodiment provides a spraying mechanism, including a protective unit 1 and a swinging unit 2.

[0029] Preferably, the protective unit 1 is formed by a base 11, a front side plate 12 and a rear side plate 13. The front side plate 12 and the rear side plate 13 are movably connected to the base 11 through protrusions provided on the base 11. In this embodiment, the front side plate 12 and the rear side plate 13 are connected to the protrusions provided on the base 11 by screws.

[0030] Preferably, the swing unit 2 includes a swing assembly 21 and a nozzle assembly 22. The nozzle assembly 22 is disposed on the swing assembly 21. The nozzle assembly 22 deflects at an angle as the swing assembly 21 rotates. The swing assembly 21 is disposed within the space enclosed by the base 11, the front side plate 12 and the rear side plate 13.

[0031] In use, the swing assembly 21 is set in the space enclosed by the base 11, the front side plate 12 and the rear side plate 13. The swing assembly 21 is protected by the front side plate 12 and the rear side plate 13 to avoid damage. The nozzle assembly 22 is set on the swing assembly 21. The nozzle assembly 22 deflects at an angle as the swing assembly 21 rotates, thereby achieving a wider spraying effect.

[0032] Figures 3-6 As an optional embodiment, an arc groove 121 is provided on the front side plate 12. The arc groove 121 is provided on both sides of the front side plate 12 and penetrates through both side walls of the front side plate 12. The arc angle of the arc groove 121 is the rotation space of the spray gun connector 213 when the motor 215 rotates.

[0033] Preferably, the swing assembly 21 includes a connecting block 211, a swing connector 212, a spray gun connector 213, a reducer 214, and a motor 215. The connecting block 211 is disposed on the base 11, the motor 215 is disposed on one side of the connecting block 211, and the motor 215 is meshed with the reducer 214. The swing connector 212 is disposed on the other side of the connecting block 211 and is movably connected to the reducer 214. The spray gun connector 213 is movably connected to the swing connector 212. That is, the rotation of the motor 215 is reduced by the reducer 214, and the rotation of the reducer 214 drives the swing connector 212 to rotate. The spray gun connector 213 is disposed on the swing connector 212 and rotates with the swing connector 212.

[0034] Furthermore, the swing connector 212 includes a rotating component 2121, a housing 2122, and a transmission component 2123. The rotating component 2121 and the transmission component 2123 are disposed within the housing 2122, and the transmission component 2123 is movably connected to the rotating component 2121. In this embodiment, the transmission component 2123 is composed of a gear set consisting of multiple gears disposed within the housing 2122. The reducer 214 is meshed with the transmission component 2123 through the connecting hole 21221. The rotating component 2121 and the transmission component 2123 are meshed together, and the rotating component 2121 rotates within the housing 2122 along with the transmission component 2123.

[0035] Furthermore, the rotating component 2121 is provided with a clamping hole 21211, and the spray gun connector 213 is disposed through the clamping hole 21211.

[0036] Furthermore, the spray gun connector 213 includes a rod 2131 and a clamping head 2132, with the clamping head 2132 disposed at both ends of the rod 2131.

[0037] Furthermore, the rod 2131 is disposed through the clamping hole 21211. The rod 2131 rotates with the rotating component 2121. That is, the rotation of the motor 215 drives the transmission component 2123 to rotate after the speed reduction of the reducer 214. The transmission component 2123 is meshed with the rotating component 2121. The rotating component 2121 rotates in the housing 2122. The rod of the spray gun connector 213 is disposed in the clamping hole 21211. Therefore, when the rotating component 2121 rotates, the spray gun connector 213 rotates around the rod as the axis.

[0038] Preferably, the nozzle assembly 22 includes a spray gun 221, a connector 222 and a pipe 223. The spray gun 221 is clamped on the spray gun connector 213. The pipe 223 and the spray gun 221 are sealed together through the connector 222. The pipe 223 is connected to the fire extinguishing gas source.

[0039] Furthermore, the spray gun 221 is clamped onto the clamping head 2132.

[0040] In use, the motor 215 rotates and is reduced in speed by the reducer 214, which drives the transmission component 2123 to rotate. The transmission component 2123 is meshed with the rotating component 2121. The rotating component 2121 rotates inside the housing 2122. The rod of the spray gun connector 213 is set in the clamping hole 21211. Therefore, when the rotating component 2121 rotates, the spray gun connector 213 rotates around the rod 2131 as the axis. The spray gun 221 is clamped on the clamping head 2132. The spray gun 221 deflects at an angle with the rod 2131, so that the spray gun 221 produces a wider range of spray. In this embodiment, the angle range generated by the above structure of the spray gun 221 is -30° to 30° oscillation.

[0041] Figure 7 As an optional embodiment, the lifting unit 3 includes a lifting component 31, the top of which is disposed on the bottom side of the base 11, and the lifting component 31 can adjust the height range of the spray gun 221.

[0042] In use, the top of the lifting component 31 is located on the bottom side of the base 11. The lifting component 31 can adjust the spray height range of the spray gun 221. Combined with the angle swing of the spray mechanism, it can achieve the function of spraying over a wide range.

[0043] Finally, it should be noted that the methods and devices described in detail above are merely embodiments, and those skilled in the art can modify these embodiments in different ways as long as they do not depart from the scope of this utility model.
