Description

Technical Field

[0001] This invention belongs to the field of fire extinguisher cleaning, specifically a cleaning device for the inside of fire extinguisher bottles. Background Technology

[0002] Liquid fire extinguishers include water-based, foam, and wet chemical fire extinguishers. Due to factors such as long-term storage, extinguishing agent deterioration, pressure drop inside the bottle, and corrosion risk, the extinguishing agent needs to be refilled regularly to ensure its effectiveness and safety. During the refilling process, a cleaning device needs to be used to thoroughly clean the inner wall of the fire extinguisher bottle to remove residues and corrosion marks.

[0003] A patent application with publication number CN219151062U discloses a cleaning device for the inside of a fire extinguisher bottle, including an adjustable nozzle; it also includes: a corrugated pipe installed on the adjustable nozzle; a water supply unit installed at one end of the corrugated pipe, the water supply unit including a base and a metal mesh fixed on the base; a double external thread connector installed on the metal mesh; a nozzle corrugated pipe installed at one end of the double external thread connector, and the other end connected to the base corrugated pipe.

[0004] The cleaning device described above includes a nozzle, a corrugated pipe, and a brush. The brush is mounted on the nozzle. During cleaning, the nozzle is inserted into the fire extinguisher bottle, and cleaning fluid is delivered through the corrugated pipe. The nozzle is controlled to rotate inside the bottle, and the brush contacts the inner wall to scrub. Different parts of the fire extinguisher bottle can be cleaned from all angles by adjusting the angle of the corrugated pipe. However, adjusting the angle of the corrugated pipe in all aspects is difficult and hard to control precisely, resulting in unsatisfactory cleaning results.

[0010] Preferably, the device further includes: a first sliding groove formed on the first ring, with the second plate slidably connected to the first sliding groove; a second sliding groove formed on the first ring, one end of the second sliding groove communicating with the first sliding groove, the third plate rotating on the second sliding groove, and after the third plate rotates to the connection point between the second sliding groove and the first sliding groove, the third plate can slide up and down with the second sliding groove; a first spring installed between the third plate and the fourth plate, and the connecting pipe adopting a telescopic structure.

[0011] Preferably, the device further includes: a connecting pipe, on which two No. 3 threaded pipes are rotatably mounted, the connecting pipe being connected to the No. 4 plate and the spray pipe simultaneously through the two No. 3 threaded pipes; a slider slidably mounted on the water outlet pipe, the slider being marked; and a No. 2 spring mounted on the slider and the water outlet pipe.

[0012] Preferably, the device further includes a No. 4 threaded tube, which is fixedly connected to the No. 1 rod, and the No. 1 rod is fixedly connected to the No. 1 plate through the No. 4 threaded tube.

[0013] Preferably, the device further includes a first wiping cloth, one end of which is fixedly fitted with a connecting rope, and a fifth threaded tube is installed on the connecting rope. The connecting rope is connected to the first plate through the fifth threaded tube and the threaded groove.

[0014] Preferably, the connecting rope is made of a telescopic material, and a metal ring is installed at the other end of the first wiping cloth. A No. 6 threaded tube rotates on the metal ring and is threadedly connected to the water outlet pipe.

[0015] Preferably, the device further includes: a plurality of first buckles installed on the airbag; and a second cleaning cloth for cleaning the inner wall of the fire extinguisher, wherein the second cleaning cloth is equipped with second buckles that cooperate with the first buckles.

[0016] The beneficial effects of the present invention are as follows: 1. The fire extinguisher bottle cleaning device of the present invention, by setting up a No. 1 rod, a No. 2 rod, and a No. 3 rod, can adapt to fire extinguisher bottles of different sizes and shapes, improving cleaning efficiency and effect. In conjunction with the airbag, the airbag can fully clean the inside of the fire extinguisher, ensuring no dead corners and cleaning more thoroughly. Moreover, compared with the No. 3 rod, the contact surface between the airbag and the inner wall of the fire extinguisher is larger, so fewer rotations are needed and cleaning is more efficient.

When used with the No. 6 threaded tube to wipe the inner wall of the fire extinguisher, different parts of the wiping cloth can come into contact with the inner wall of the fire extinguisher, so that the wiping cloth can absorb more moisture, thereby improving the wiping efficiency.

[0019] 4. The fire extinguisher cylinder cleaning device of the present invention, through the design of a No. 4 threaded tube, allows the No. 1, No. 2, and No. 3 rods to be detached from the No. 1 plate, leaving only the airbag. Different length rods can be selected for installation according to the size of the internal space of the fire extinguisher, or can be installed according to the cleaning needs of the fire extinguisher. For routine cleaning or when the inner wall has a coating, only the airbag can be selected. For heavy dirt, where the frame needs to transmit torque, the No. 1, No. 2, and No. 3 rods can be installed to enhance the cleaning power. This modular design makes the device more practical.

Detailed Implementation

[0023] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0024] like Figures 1-12As shown, the cleaning device inside the fire extinguisher bottle of this embodiment includes a circular shell 1 and a spray pipe 2 for spraying water. It also includes: a first ring 3 slidably mounted on the circular shell 1, with the spray pipe 2 located inside the first ring 3; a first plate 4 mounted on the first ring 3; and several first rods 5, second rods 6, and third rods 7 mounted on the first plate 4. The second rod 6 is rotatably connected to the first rod 5, and the third rod 7 is rotatably connected to the second rod 6. The connection points of the first rod 5, the second rod 6, and the third rod 7 are respectively provided with a first torsion spring 8 and a second torsion spring 9. When the first rod 5, the second rod 6, and the third rod 7 are unfolded, they form an inverted U-shape. The third rod 7 is in contact with the inner wall of the fire extinguisher. The second rod 6 adopts a telescopic structure.

[0025] Specifically, the existing cleaning device includes a nozzle 2, a corrugated pipe, and a brush. The brush is mounted on the nozzle 2. During cleaning, the nozzle 2 is inserted into the fire extinguisher bottle, and the cleaning fluid is delivered through the corrugated pipe. The nozzle 2 is controlled to rotate inside the bottle, and the brush contacts the inner wall to scrub. Different parts of the fire extinguisher bottle can be cleaned from all angles by adjusting the angle of the corrugated pipe. However, it is difficult to adjust the angle of the corrugated pipe in all aspects, making it difficult to control precisely and resulting in unsatisfactory cleaning effect. Initially, rods 5, 6, and 7 are all located inside ring 3, and torsion springs 8 and 9 are in a torsional state. When operation is required, ring 3 is slid, and rods 5, 6, and 7 unfold sequentially under the elastic force of torsion springs 8 and 9. Figure 4As shown, depending on the material of the fire extinguisher bottle, different cleaning tools such as cleaning cloths, sponges, or brushes of different materials can be fitted onto rods 6 and 7 to adapt to the cleaning needs of different inner wall materials. Then, slide ring 3 to retract rods 5, 6, and 7 into the round shell 1 in sequence. Remove the valve and siphon tube of the fire extinguisher. Then, invert the fire extinguisher onto the open shelf that exposes the bottle opening. Insert the round shell 1 into the fire extinguisher. Then, slide ring 3 upward to unfold rods 5, 6, and 7 under the action of torsion springs 8 and 9. At this time, rod 7 contacts the side wall of the fire extinguisher bottle, and rod 6 contacts the bottom of the fire extinguisher bottle. Then, slide the nozzle 2 out of the round shell 1 and connect the nozzle 2 to the water supply system. Activate the nozzle 2 to spray water into the fire extinguisher bottle. Then, rotate the round shell 1 to retract rods 6 and 7. Rotating the cylinder and moving the circular shell 1 up and down simultaneously moves levers 6 and 7, allowing lever 7 to clean the inner wall of the extinguisher bottle and lever 6 to clean the bottom. During cleaning, lever 6 extends and retracts to accommodate different cleaning needs. For the bottle opening, lever 6 can be fully retracted into the circular shell 1, while lever 7 is extended or partially extended. Then, rotating the circular shell 1 allows the end of lever 7 to clean the bottle opening. After cleaning, sliding ring 3 retracts levers 7, 6, and 5 completely into the circular shell 1, ensuring all components are back in place for easy storage and future use. This achieves comprehensive and efficient cleaning of the extinguisher bottle's interior. By using levers 5, 6, and 7, the system can accommodate extinguisher bottles of different sizes and shapes, ensuring thorough cleaning and improving efficiency and effectiveness.

[0026] like Figure 3 , Figure 7 , Figure 8 and Figure 10 As shown, the device also includes: several threaded grooves 10 formed on a first plate 4; an airbag 11, on which several first threaded tubes 12 are rotatably mounted; the first plate 4 has a hollow structure; the airbag 11 is connected to the first plate 4 through the first threaded tubes 12 and the threaded grooves 10; the first rod 5, the second rod 6, and the third rod 7 are all located on the outside of the airbag 11; a second plate 13 mounted on a first ring 3, with a first hole 14 formed on the second plate 13; a cavity 15 formed between the second plate 13 and the first ring 3; the cavity 15 is connected to the first plate 4 and the airbag 11; a third plate 16 rotatably mounted on the first ring 3, with a second hole 17 formed on the third plate 16; and a fourth plate 18 rotatably mounted on the first ring 3, with a connecting pipe 19 installed between the fourth plate 18 and the third plate 16; the fourth plate 18 is connected to the third plate 16 through the connecting pipe 19.

[0027] Specifically, in the initial state, holes 14 and 17 on plate 16 and plate 13 are aligned. Before operation, plate 18 is connected to the air pump. A rope is installed on the airbag 11, which connects the airbag 11 to rods 5, 6, and 7. The rope on the airbag is used to keep rods 5, 6, and 7 in the same direction as the airbag before operation, ensuring that rods 7, 6, and 5 are completely retracted into the shell 1 and do not shake easily. During operation, insert the round shell 1 into the fire extinguisher cylinder. Then slide the first ring 3 to unfold the first lever 5, the second lever 6, and the third lever 7. After unfolding, control the air pump to inflate the fourth plate 18. The gas enters the third pipe through the connecting pipe, and then enters the cavity 15 through the first hole 14 and the second hole 17. It then enters the airbag 11 through the first plate 4. Air is injected into the airbag 11, and the airbag 11 expands and unfolds, fitting tightly against the inside of the fire extinguisher cylinder (e.g., ...). Figure 6 As shown, levers 5 (number one), 6 (number two), and 7 (number three) form the framework of the airbag 11 and do not contact the inner wall of the fire extinguisher bottle. After the airbag 11 is inflated, the circular shell 1 is rotated, causing levers 5 (number one), 6 (number two), 7 (number three), and the airbag 11 to rotate synchronously. The rotation of the airbag 11 cleans the bottom of the fire extinguisher bottle. Then, the circular shell 1 slides downwards to wipe the side wall of the fire extinguisher, thus achieving the cleaning action. By designing the airbag 11, it can fully contact the inside of the fire extinguisher, ensuring no dead corners and a more thorough cleaning. Compared to lever 7 (number three), the contact area between the airbag 11 and the inner wall of the fire extinguisher is larger, thus requiring fewer rotations and more efficient cleaning.

[0028] like Figure 3 , Figure 4 and Figure 7 As shown, the device also includes: a water outlet pipe 20 installed inside the first ring 3, with the nozzle 2 located inside the water outlet pipe 20; a rubber skin 21 installed on the airbag 11, with a second threaded pipe 22 rotatably installed on the rubber skin 21, the second threaded pipe 22 being threadedly connected to the water outlet pipe 20, and the other end of the rubber skin 21 being connected to the airbag 11.

[0029] Specifically, before operation, one end of the rubber sheet 21 is connected to the water outlet pipe 20 through the No. 2 threaded pipe 22. During operation, after the airbag 11 is fully inflated, the airbag 11 is pressed tightly against the inner wall of the fire extinguisher, dividing the space inside the fire extinguisher into two. When the airbag 11 wipes the inner wall of the fire extinguisher, the wastewater generated flows into the water outlet pipe 20 through the rubber sheet 21 and is discharged from the water outlet pipe 20. This prevents the wastewater generated at the bottom of the bottle from flowing down to the uncleaned area and causing secondary pollution, thus achieving effective isolation of wastewater during the cleaning process and ensuring cleaning effect and efficiency.

[0030] like Figure 7 , Figure 8 and Figure 10As shown, the device also includes: a first slide groove 23 formed on the first ring 3, with the second plate 13 slidably connected to the first slide groove 23; a second slide groove 24 formed on the first ring 3, with one end of the second slide groove 24 connected to the first slide groove 23; a third plate 16 rotating on the second slide groove 24; after the third plate 16 rotates to the connection point between the second slide groove 24 and the first slide groove 23, the third plate 16 can slide up and down with the second slide groove 24; a first spring 25 installed between the third plate 16 and the fourth plate 18; and a telescopic structure for the connecting pipe 19.

[0031] Specifically, before operation, the third plate 16 is rotated so that it aligns with holes 14 and 17 of the second plate 13. At this point, the third plate 16 cannot slide within the first groove 23. After the airbag 11 is fully inflated, the fourth plate 18 is rotated to drive the third plate 16 to rotate synchronously. The third plate 16 rotates to the connection point of the first groove 23 and the second groove 24. At this point, holes 14 and 17 are misaligned, preventing gas leakage. When the airbag 11 moves to a smaller area within the fire extinguisher, the air pressure inside the airbag 11 increases. Therefore, the second plate 13 and the third plate 16 slide within the first groove under pressure. The sliding mechanism 23 increases the volume of cavity 15 to balance the internal pressure of airbag 11 and prevent it from rupturing. At this time, spring 25 is compressed. When airbag 11 moves to a larger space, the internal pressure decreases. Plates 13 and 16 reset under the action of spring 25, reducing the volume of cavity 15 and maintaining the stability of airbag 11, so that cleaning can start again from the bottom of the bottle. Through this adjustment mechanism, the dynamic balance of the internal pressure of airbag 11 is achieved, ensuring efficient cleaning inside fire extinguishers of different sizes. At the same time, the fire extinguisher can be cleaned multiple times without inflation and deflation, making it convenient to use.

[0032] like Figure 9 As shown, the device also includes: a connecting pipe 26, on which two No. 3 threaded pipes 27 are rotatably mounted, and the connecting pipe 26 is simultaneously connected to the No. 4 plate 18 and the spray pipe 2 through the two No. 3 threaded pipes 27; a slider 28 slidably mounted on the water outlet pipe 20, and a mark is provided on the slider 28; and a No. 2 spring 29 mounted on the slider 28 and the water outlet pipe 20.

[0033] Specifically, before inflation, the connecting pipe 26 is connected to the fourth plate 18 and the nozzle 2 by rotating the No. 3 threaded pipe 27. Then, the connecting pipe 26 is connected to the inflation pump, and the outlet of the water pipe 20 is blocked. During inflation, the inflation pump is started, and gas enters the fourth plate 18 and the nozzle 2 through the connecting pipe 26. The gas entering the fourth plate 18 inflates the airbag 11, and at the same time, the gas enters the nozzle 2 and is sprayed out. If the airbag 11 is not fully inflated, the gas can be discharged from the nozzle of the fire extinguisher. If the airbag 11 is fully inflated and in close contact with the inner wall of the fire extinguisher, the gas cannot be discharged, and the air pressure increases. Since the water pipe 20 is connected to it, the slider 28 can slide out under the action of air pressure until the mark on the slider 28 appears, indicating that inflation is complete, and inflation of the fire extinguisher can be stopped. Through this air pressure feedback mechanism, the inflation status of the airbag 11 is ensured to be accurate, avoiding over-inflation or under-inflation.

[0034] like Figure 3 and Figure 5 As shown, the device also includes a No. 4 threaded tube 30, which is fixedly connected to the No. 1 rod 5. The No. 1 rod 5 is fixedly connected to the No. 1 plate 4 through the No. 4 threaded tube 30.

[0035] Specifically, by setting up the No. 4 threaded pipe 30, the No. 1 rod 5, No. 2 rod 6, and No. 3 rod 7 can be removed from the No. 1 plate 4, leaving only the airbag 11. Different length rods can be selected for installation according to the size of the fire extinguisher's internal space, or they can be installed according to the cleaning needs of the fire extinguisher. For example, for regular cleaning or when the inner wall has a coating, only the airbag 11 can be selected. For heavy dirt, where the frame needs to transmit torque, the No. 1 rod 5, No. 2 rod 6, and No. 3 rod 7 can be installed to enhance the cleaning power. This modular design makes the device more practical.

[0036] like Figure 11 and Figure 12 As shown, the device also includes a first wiping cloth 31, one end of which is fixedly installed with a connecting rope 32. A fifth threaded tube 33 is installed on the connecting rope 32, and the connecting rope 32 is connected to the first plate 4 through the fifth threaded tube 33 and the threaded groove 10.

[0037] Specifically, after cleaning, the No. 1 rod 5 can be disassembled by rotating the No. 4 threaded tube 30. Then, the No. 1 wiping cloth 31 is installed on the No. 1 plate 4 through the No. 5 threaded tube 33. The No. 1 wiping cloth 31 is fitted onto the outer layer of the airbag 11. Then, the round shell 1 is reinserted into the fire extinguisher, and the airbag 11 is re-inflated. After the airbag 11 is inflated, the No. 1 wiping cloth 31 is pressed tightly against the inner wall. Then, the round shell 1 is rotated and slid up and down to drive the No. 1 wiping cloth 31 and the airbag 11 to wipe in all directions to wipe away the residual moisture in the fire extinguisher after cleaning, reduce moisture residue, improve the drying speed of the fire extinguisher, and improve the cleaning speed of the fire extinguisher.

[0038] like Figure 11 and Figure 12 As shown, the connecting rope 32 is made of telescopic material, and a metal ring 34 is installed at the other end of the first wiping cloth 31. A No. 6 threaded tube 35 rotates on the metal ring 34 and is threadedly connected to the water outlet pipe 20.

[0039] Specifically, the No. 6 threaded pipe 35 is internally threaded to the water outlet pipe 20, and the No. 2 threaded pipe 22 is externally threaded to the water outlet pipe 20. When installing the wiping cloth, remove the No. 2 threaded pipe 22 from the water outlet pipe 20 and screw the No. 6 threaded pipe 35 into the water outlet pipe 20. When wiping the inner wall of the fire extinguisher, the No. 1 wiping cloth 31 can be slid by sliding the water outlet pipe 20, so that different parts of the wiping cloth can contact the inner wall of the fire extinguisher, allowing the wiping cloth to absorb more moisture and thus improve wiping efficiency.

[0040] like Figure 6 As shown, the device also includes: a number of first buckles 36 installed on the airbag 11; and a second cleaning cloth 37 for cleaning the inner wall of the fire extinguisher, on which a second buckle 38 is installed to cooperate with the first buckle 36.

[0041] Specifically, by setting the No. 1 buckle 36 and the No. 2 buckle 38, a No. 2 wiping cloth 37 with different roughness can be installed on the airbag 11 according to the cleaning needs of the fire extinguisher, so as to achieve targeted wiping of the inner wall of the fire extinguisher during the cleaning process and improve the cleaning effect.

[0042] Working principle: In the initial state, lever 5, lever 6, and lever 7 are all located inside ring 3, and torsion springs 8 and 9 are in a torsional state. Depending on the material of the extinguishing gas cylinder, different materials of cleaning cloths 31 are installed on the surface of the airbag 11. During operation, the valve and siphon tube of the extinguisher are removed. The extinguisher is then inverted on a perforated frame that exposes the cylinder opening. The round shell 1 is inserted into the extinguisher. Ring 3 is then slid upwards, causing levers 5, 6, and 7 to unfold under the action of torsion springs 8 and 9. The extinguisher is then rotated... Connect the threaded pipe 27 to the connecting pipe 26, which is then connected to the fourth plate 18 and the nozzle 2. Next, connect the connecting pipe 26 to the air pump, and block the outlet of the water pipe 20. Then, control the air pump to inflate the connecting pipe 26. The gas enters the fourth plate 18 and the nozzle 2 through the connecting pipe 26. The gas entering the fourth plate 18 inflates the airbag 11, and simultaneously enters the nozzle 2 and is ejected. If the airbag 11 is not fully inflated, the gas can be discharged from the fire extinguisher's nozzle. If the airbag 11 is fully inflated, it expands and tightly seals against the inside of the fire extinguisher cylinder (e.g., ...). Figure 6As shown), the gas cannot escape, the air pressure increases, and the water outlet pipe 20 is connected to it. Therefore, the slider 28 can slide out under the action of air pressure until the mark on the slider 28 appears, indicating that the inflation is complete and the inflation of the fire extinguisher can be stopped. The first lever 5, the second lever 6, and the third lever 7, as the skeleton of the airbag 11, do not contact the inner wall of the fire extinguisher bottle. After the airbag 11 is fully inflated, the connecting pipe 26 is removed, the water outlet pipe 20 is connected to the wastewater collection system, and the spray pipe 2 is connected to the water supply system. The spray pipe 2 is activated to spray water into the fire extinguisher bottle. Then, the round shell 1 is rotated, which drives the airbag 11 to rotate. While rotating, the round shell 1 is moved up and down, which drives the airbag 11 to move. The inner wall of the bottle can be wiped clean by the third lever 7, and the bottom of the bottle can be wiped clean by the second lever 6. During the cleaning process, the second lever 6 The retractable design adapts to the cleaning needs of different parts. When the airbag 11 wipes the inner wall of the fire extinguisher, the wastewater generated flows into the outlet pipe 20 through the rubber skin 21 and is discharged from the outlet pipe 20. After cleaning, the first rod 5 can be removed by rotating the No. 4 threaded tube 30. Then, the first wiping cloth 31 is installed on the first plate 4 through the No. 5 threaded tube 33. The first wiping cloth 31 is fitted onto the outer layer of the airbag 11. Then, the round shell 1 is reinserted into the fire extinguisher, and the airbag 11 is re-inflated. After the airbag 11 expands, the first wiping cloth 31 is pressed tightly against the inner wall. Then, the round shell 1 is rotated and slid up and down to drive the first wiping cloth 31 and the airbag 11 to wipe in all directions to remove the residual water in the fire extinguisher after cleaning, reduce water residue, improve the drying speed of the fire extinguisher, and improve the cleaning speed of the fire extinguisher.
