[0002] Firefighting equipment refers to light firefighting tools and equipment used for emergency treatment. The most common one is the fire extinguisher, which is mainly composed of a cylinder, a head, a nozzle and other parts.

Fire extinguishers are generally hollow cylindrical, with the interior used to store fire extinguishing agents. They are made of iron-based alloy materials.

[0032] The rotating member 20 includes a mounting plate 28 coaxially fixedly mounted on the bottom end of the support rod 4. The support rod 4 passes through the conveying disc 2. The top surface of the mounting plate 28 is rotatably fitted with the bottom surface of the conveying disc 2. A plurality of sets of sliding grooves 29 are evenly arranged on the mounting plate 28. A tooth block 30 capable of meshing with the driving gear 18 is slidably connected in the sliding groove 29. One end of the tooth block 30 is fixedly connected to a second spring 31 fixedly connected to the sliding groove 29.

[0033] The suction mechanism 9 also includes a collecting cylinder 32 fixedly mounted on the body 1, and a collecting groove 33 is provided on the side of the collecting cylinder 32 facing the spray rod 7. The collecting cylinder 32 passes through the conveying disk 2 and the rotating disk 21, and is rotatably connected to the conveying disk 2 and the rotating disk 21. The bottom end of the collecting cylinder 32 is rotatably connected to a driving ring 34, the outer wall of the impeller 10 is fixedly connected to the inner wall of the driving ring 34, the outer wall of the pulley 16 is transmission-connected to a transmission belt 35 transmission-connected to the outer wall of the driving ring 34, and a collecting member 36 for filtering and collecting the collected aerosol is provided in the body 1.

[0034] The collecting member 36 includes a collecting box 37 slidably connected to the machine body 1 in a horizontal direction. The bottom end of the driving ring 34 is connected to the collecting box 37 . An exhaust hole 38 is provided on the side of the collecting box 37 . A filter screen 39 is fixedly connected inside the collecting box 37 .

[0035] The spraying mechanism 6 also includes a storage box 40 fixedly mounted on the body 1, the storage box 40 is used to store anti-rust paint, the spraying rod 7 is fixedly connected to the side of the storage box 40, the nozzle 8 is used to spray the paint in the storage box 40, and the spraying rod 7 is bent to enable the nozzle 8 to evenly spray the top and sides of the fire extinguisher.

[0036] In this embodiment, the narrow opening of the upper end of the fire extinguisher is in an unsealed state during spraying. At this time, the narrow opening of the upper end of the fire extinguisher is inserted downwardly toward the top of the lifting rod 11. The elastic force of the first spring 12 is relatively small, and it is only used to push the lifting rod 11 to move up and reset. When the top of the lifting rod 11 is subjected to force, the lifting rod 11 presses down the first spring 12, so that the first connecting rod 13 and the second connecting rod 14 on both sides rotate, and the hinged position of the first connecting rod 13 and the second connecting rod 14 flips outward to support the inner wall of the top of the fire extinguisher. The stability of the support process is improved by the rubber gasket 41 to prevent the fire extinguisher from being damaged. When the rubber gasket 41 is in close contact with the inner wall of the fire extinguisher, the fire extinguisher can no longer continue to press the lifting rod 11 down, and the function of automatic clamping and fixing can be realized. The device can be used for fire extinguishers with different inner diameters and heights, and the support is flexible and efficient. In the process of removing the fire extinguisher, the dried fire extinguisher can be directly lifted up, and the lifting rod 11 can be moved up under the push of the first spring 12, and the hinged position of the first connecting rod 13 and the second connecting rod 14 is flipped inward to release the resistance support to the inner wall of the fire extinguisher. Such a cycle can realize the continuous loading, spraying and unloading conveying operations of the fire extinguisher.

[0037] Start the drive motor 15 to drive the pulley 16, the drive disc 17 and the drive gear 18 to rotate synchronously. During the rotation of the drive disc 17, the drive rod 25 and the drive block 26 are driven to rotate. After the drive block 26 rotates into the drive groove 23, the rotating disc 21 can be driven to rotate at a set angle. During the rotation, the rotating disc 21 is deflected by the position of the rotating groove 27. When the drive block 26 contacts and slides with the drive groove 23, the driving disc 17 rotates to the position of the arc groove 22 again to limit the rotating disc 21. In this reciprocating manner, the driving disc 17 can drive the rotating disc 21 and the conveying disc 2 to rotate at a set angle every time it rotates one circle, thereby completing the function of switching the support rod 4 and the fire extinguisher position.

[0038] During the rotation and switching of the conveying disc 2, the support rod 4 and the mounting disc 28 will be driven to rotate and switch together. Since the driving gear 18 is continuously rotating, when the mounting disc 28 rotates to a position close to one side of the driving gear 18, the tooth block 30 on the mounting disc 28 will gradually come into conflict and mesh with the tooth groove of the driving gear 18. If the meshing cannot be completed at one time, since the tooth block 30 can slide in the sliding groove 29, the situation in which the tooth block 30 and the driving gear 18 conflict and get stuck during the rotation and switching of the mounting disc 28 is avoided. When the mounting disc 28 rotates to the set position, the driving gear 18 can drive the tooth block 30 to make the mounting disc 28 and the support rod 4 rotate, and the fire extinguisher rotates with the support rod 4. At this time, the nozzle 8 can spray the anti-rust paint in the storage box 40 onto the surface of the fire extinguisher.

[0039] After spraying is completed, the position of the mounting disk 28 and the fire extinguisher is switched again, the driving gear 18 releases the meshing state with the tooth block 30 on the mounting disk 28, and meshes and transmits with the tooth block 30 on the next group of mounting disks 28, so that the intermittent conveying switching can be achieved by only one set of driving motors 15 to drive the conveying disk 2, and at the same time, it can drive the fire extinguisher at the set position after switching to perform self-rotation spraying.

[0040] During the operation of the driving motor 15, the pulley 16 is driven to rotate. The pulley 16 drives the driving ring 34 and the impeller 10 to rotate at high speed through the transmission belt 35. The impeller 10 blows the air on one side of the collecting cylinder 32 to the collecting box 37 below, and discharges it through the exhaust hole 38, so that the aerosol diffused to the surrounding is pumped into the collecting box 37 through the collecting groove 33. The gas is discharged after being filtered by the filter 39, and the paint is filtered and collected in the collecting box 37. The internal filter 39 can be replaced by pulling out the collecting box 37, and the collected impurities can be cleaned.

[0041] The suction mechanism 9 does not require an additional driving structure. The functions of product switching transportation and rotary spraying can be achieved only through the continuous rotation of a set of driving motors 15. At the same time, it can also drive the impeller 10 to collect and transport the diffused aerosol. The structure is simple and stable, the operation is convenient and efficient, and there is no need to clamp the outer wall of the fire extinguisher so that the fire extinguisher can stably support the transmission. Only one spraying is required to complete the overall spraying operation of the side of the fire extinguisher, which greatly improves the efficiency of the fire extinguisher spraying.
