[0023] The technical solution of the utility model is further described below in conjunction with the accompanying drawings and specific embodiments.

[0024] Example

[0025] The utility model provides a smoke exhaust system for a fire-fighting robot.

[0026] like Figure 1-4As shown, the smoke exhaust system includes a fan 2, a fan mounting base 21 is fixedly connected to the bottom of the fan 2, and the fan mounting base 21 is fixedly connected to the shell of the fire extinguishing robot.

[0027] like Figure 1 As shown, one end of the fan 2 is detachably fixedly connected to a connecting pipe 11 via a connecting assembly 3, and one end of the connecting pipe 11 away from the fan 2 is fixedly connected to a smoke exhaust pipe 1 for exhausting smoke to a distant place.

[0028] like Figure 3-4 As shown, the connecting assembly 3 includes a fixed ring 31 fixedly sleeved on the outer ring surface of the fan 2, and the outer surface of the fixed ring 31 is rotatably connected to a plurality of pressure blocks 33 for clamping the connecting pipe 11 through a rotating assembly 32, and the outer surface of the fixed ring 31 is fixedly connected to a leaf spring 34 that can elastically push the pressure blocks 33.

[0029] like Figure 5 As shown, the rotating assembly 32 includes a pair of fixed blocks 321 fixedly connected to the outer surface of the fixed ring 31, a rotating shaft 322 is fixedly connected between the two fixed blocks 321, a rotating shaft sleeve 323 is fixedly connected to the outer surface of the pressing block 33, and the rotating shaft sleeve 323 is rotatably sleeved with the rotating shaft 322.

[0030] like Figure 2 As shown, the outer movable sleeve of the fan 2 is provided with a movable ring 35, the outer surface of the movable ring 35 is fixedly connected to a connecting shaft 36, and the end of the connecting shaft 36 is fixedly connected to a push ring 37. A threaded ring 38 is rotatably connected to one end surface of the movable ring 35, and the outer ring surface of the fan 2 is provided with an external threaded portion 22 that can be spirally connected to the threaded ring 38.

[0031] like Figure 6 As shown, a convex ring 12 is integrally connected to the outer ring surface of one end of the connecting pipe 11 , and a clamping groove 331 matching the convex ring 12 is formed on the outer surface of the pressing block 33 close to the connecting pipe 11 .

[0032] Working principle of this embodiment: The smoke exhaust system includes fans 2 and 1. By adding a smoke exhaust pipe 1 to the fan 2, the smoke in the fire scene can be exhausted to a farther location to expand the smoke exhaust range. In addition, the present application simplifies the difficulty of disassembly and assembly between the smoke exhaust pipe 1 and the fan 2 through the design of the connecting component 3, so that the smoke exhaust pipe 1 of different lengths can be quickly replaced and installed according to the actual fire scene situation;

[0033] Specifically, when installing and connecting the smoke exhaust pipe 1 and the fan 2, first rotate the threaded ring 38. The threaded ring 38 moves horizontally through the spiral connection with the external threaded part 22, thereby driving the push ring 37 to translate through the connecting shaft 36. The push ring 37 can horizontally push all the pressing blocks 33, and the pressing blocks 33 rotate around the rotating shaft 322. At this time, the end of the pressing block 33 close to the fan 2 rotates upward to form a space gap, and then the connecting pipe 11 is inserted into the gap. Then, the threaded ring 38 is rotated in the reverse direction to make the threaded ring 38, the connecting shaft 36 and the push ring 37 translate in the reverse direction. The leaf spring 34 will push the pressure block 33 to rotate in the reverse direction through the elastic thrust, so that the pressure block 33 is reset close to the end of the fan 2 and then presses the end of the connecting pipe 11 tightly. In the above process, the threaded ring 38 and the external threaded portion 22 may not be designed. In this case, it is only necessary to manually translate the movable ring 35, and the above-mentioned lifting of the pressure block 33 can also be achieved, but the movable ring 35 needs to be held all the time. Once the movable ring 35 is released, it will move and reset. If the threaded ring 38 and the external threaded portion 22 are used, the movable ring 35 will not reset automatically.

[0034] The implementation modes of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited thereto, and various changes can be made within the knowledge scope of technicians in the relevant technical field without departing from the purpose of the present invention.
