Description

Technical Field

[0001] The invention relates to the technical field of industrial fire fighting and disaster rescue, and in particular to a mobile smoke exhaust robot. Background Art

[0002] The fire smoke exhaust robot is an automated device used for smoke exhaust and cleanup at fire scenes. It removes thick smoke through a built-in fan and smoke exhaust system, improves vision and air quality, and ensures the safety of firefighters.

[0003] At present, the smoke exhaust method used by firefighting robots is mostly "direct exhaust", which mainly increases the smoke exhaust efficiency by setting a fan inside the wind tube to directly exhaust the smoke. However, the equipment cannot switch the working mode according to the fire environment parameters (such as dust concentration, temperature gradient, and combustible gas content). Some industrial products will produce a lot of dust after burning. If they are directly discharged, it will have a greater impact on the surrounding environment, causing the direct exhaust mode to exceed the PM2.5 emission standard. It can be seen that the existing mobile smoke exhaust robots have a contradiction between smoke exhaust efficiency and dust filtration due to the solidification of their functional modes.

[0021] In the above structure, reference Figure 2 , Figure 6 and Figure 7 A protective net 11 is fixedly connected to the front end of the smoke exhaust pipe 10 , a retaining ring 12 is fixedly connected to the surface of the smoke exhaust pipe 10 , a sprinkler head 13 is fixedly connected to the inner wall of the retaining ring 12 , and a smoke exhaust fan 14 is fixedly connected to the interior of the smoke exhaust pipe 10 .

[0022] Through the above-mentioned structural design, the direct-discharge workflow is as follows: when the robot is in use, it first controls the crawler transmission mechanism 2 to drive the device as a whole to move into the fire scene. After completion, the servo motor 8 is turned on. The servo motor 8 drives the transmission shaft 9 to rotate. While the transmission shaft 9 rotates, it can drive the smoke exhaust pipe 10 to adjust the angle. After the smoke exhaust pipe 10 is adjusted to a suitable angle, the smoke exhaust fan 14 is controlled to open. After the smoke exhaust fan 14 is turned on, the smoke inside the fire scene can be discharged to the outside.

[0023] Further, if Figures 3 to 5 As shown, a tank support 16 is fixedly connected in the middle of the bearing base 6, an articulated seat 17 is symmetrically fixedly connected to one end of the tank support 16, an axle rod 18 is rotatably connected inside the articulated seat 17, a clamping rod 19 is fixedly connected to the surface of the axle rod 18, a clamping block 20 is fixedly connected to the surface of the clamping rod 19, a torsion spring 21 is sleeved on the surface of the axle rod 18, and both ends of the torsion spring 21 are fixedly connected to the articulated seat 17 and the axle rod 18 respectively.

[0024] like Figures 8 to 10 As shown, the inside of the tank support 16 is connected to the filter tank 22 by the clamping block 20, and the inside of the filter tank 22 is rotatably connected to the stirring shaft 23, one end of the stirring shaft 23 extends to the outside of the filter tank 22, and the surface of the stirring shaft 23 is fixedly connected to the stirring blade 24. The top surface of the body carrier 1 is fixedly connected to the support plate 25, and the surface of the support plate 25 is fixedly connected to the reduction motor 26, and the transmission end of the reduction motor 26 is rotatably connected to the rotating shaft 27.

[0025] In this embodiment, the end of the rotating shaft 27 away from the reduction motor 26 is fixedly connected with a transmission coupling 28, and the end of the stirring shaft 23 close to the transmission coupling 28 is fixedly connected with a driven coupling 29, and the transmission coupling 28 is connected with the driven coupling 29 by a clamping connection. The end of the smoke exhaust pipe 10 away from the protective net 11 is threadedly connected with a closing cover 30, and a high temperature resistant hose 31 is fixedly connected inside the closing cover 30. A hard conduit 32 is fixedly connected inside the support plate 25, and the hard conduit 32 is fixedly connected to the end of the high temperature resistant hose 31 away from the closing cover 30.

[0026] In addition, a connecting pipe 33 is fixedly connected to the surface of the filter tank 22, and the connecting pipe 33 is connected to the filter tank 22. A top ring 34 is slidably connected to the inner wall of the connecting pipe 33. A fixed shaft 35 is fixedly connected to the inside of the top ring 34. A closing plug 36 is fixedly connected to the end of the fixed shaft 35 away from the top ring 34. The closing plug 36 is inserted into the connection between the connecting pipe 33 and the filter tank 22, and a spring 37 is arranged inside the connecting pipe 33.

[0027] One end of the hard conduit 32 away from the high temperature resistant hose 31 is plugged into the inside of the connecting pipe 33, and the connecting pipe 33 is in close contact with the surface of the top ring 34. An exhaust structure 5 is fixedly connected to the surface of the filter tank 22, and the exhaust structure 5 extends to the upper ends of the crawler drive mechanisms 2 on both sides, and the exhaust structure 5 is connected to the filter tank 22.

[0028] The filter tank is fixed by setting a clamping block. Due to different fire environments, most equipment needs to be used for a long time. By toggling the clamping rod, the clamping block can stop limiting the filter tank. On the contrary, the filter tank can be quickly fixed by plugging it into the tank support, so that the filter tank can be quickly replaced, and the equipment can be used continuously for a long time. In addition, by setting a closing plug and a top ring, when the filter tank is replaced, the hard conduit is inserted into the inside of the connecting pipe to push out the closing plug, so that the filter tank and the high-temperature resistant hose can be quickly connected.

[0029] Through the above structural design, the closed filtering process is as follows: in an environment with high dust concentration or excessive toxic gas. The closed cover 30 is threadedly locked with the smoke exhaust pipe 10, the high temperature hose 31 and the hard conduit 32 form a closed air duct, the servo motor 8 drives the smoke exhaust pipe 10 to tilt down 15° to ensure the optimal smoke introduction angle, the smoke exhaust fan 14 slows down to 1500rpm, the smoke enters the hard conduit 32 through the high temperature hose 31, the top ring 34 is compressed by the thrust of the hard conduit 32 The spring 37, the closing plug 36 releases the blockage of the connecting pipe 33, the smoke is injected into the filter tank 22 below the liquid level through the connecting pipe 33, the flocculant is pre-placed in the water to capture PM2.5 particles, the reduction motor 26 drives the stirring shaft 23 to rotate at 120rpm, and the stirring blades 24 break the bubbles into microbubbles <1mm, and the gas-liquid contact area is increased. After the absorption is completed, the clamping block 20 is pressed to trigger the torsion spring 21 to release the torque, and the filter tank 22 quickly detaches from the tank support 16. When a new filter tank is inserted, the driving coupling 28 and the driven coupling 29 are automatically aligned by magnetic attraction. Those skilled in the art should know that the drawings in this embodiment are only for reference, and the actual volume of the filter tank 22 can be set larger to facilitate the smooth inhalation of a large amount of smoke.

[0030] Specifically, after the pollutants inside the filter tank 22 are full, the clamping block 20 is toggled to make the torsion spring 21 rotate on the surface of the clamping rod 19, and the clamping rod 19 stops limiting the filter tank 22 while rotating. At this time, the filter tank 22 can be taken out from the middle of the tank support 16, and a new filter tank 22 is taken out and plugged into the middle of the tank support 16. When the filter tank 22 is plugged in, the clamping block 20 is squeezed to make it flip to both sides, and at the same time, the connecting pipe 33 is aligned with the hard conduit 32 and plugged into the inside of the connecting pipe 33. After the hard conduit 32 is plugged into the inside of the connecting pipe 33, it is pushed The top ring 34 moves backward and squeezes the spring 37. While the top ring 34 moves, it pushes the closing plug 36 through the fixed shaft 35 to stop blocking the connection between the filter tank 22 and the connecting pipe 33, so that the connection between the filter tank 22 and the hard conduit 32 can be achieved; after the filter tank 22 moves to a suitable position, the torsion spring 21 drives the shaft 18 to rotate, and then drives the clamping block 20 to flip through the clamping rod 19 to limit the filter tank 22. While the filter tank 22 moves, the driven coupling 29 is plugged into the middle of the transmission coupling 28, so that the filter tank 22 can be quickly replaced.

[0031] The mobile smoke exhaust robot provided in the above embodiment works by switching between direct exhaust and closed dual working modes. In direct exhaust mode, the servo motor drives the smoke exhaust pipe to exhaust smoke at high speed in a directional manner to achieve high-flow direct exhaust; in closed mode, the smoke is introduced into the filter tank through a high-temperature resistant hose, and the pollutants are adsorbed by water molecules through the gas-liquid turbulent stirring system to avoid high-dust gas from being directly discharged and polluting the air, solving the technical problem of functional rigidity of traditional equipment.

[0032] In order to make it easier for ordinary technicians in the field to understand the improvements of the present invention over the prior art, some drawings and descriptions of the present invention have been simplified, and the above-mentioned embodiments are preferred implementation schemes of the present invention. In addition, the present invention can also be implemented in other ways. Any obvious replacement without departing from the concept of the present technical solution is within the protection scope of the present invention.
