Description

Technical Field

[0001] This invention relates to the field of cleaning equipment technology, specifically to a fire hose cleaning device for fire protection engineering. Background Technology

[0002] Fire hoses play a crucial role in firefighting operations, delivering high-pressure water or flame-retardant media such as foam to ensure the smooth progress of firefighting and rescue work. The core of the hose is an inner rubber lining that prevents water leakage during transport, while the outer layer uses a flax braided layer to enhance its resilience. Fire hoses are typically equipped with standard metal connectors at both ends. These connectors not only facilitate the quick connection and disconnection of multiple hose sections to expand coverage, but also allow for easy docking with specialized nozzles, improving extinguishing pressure and efficiency.

[0003] Although fire hoses perform excellently in actual use, post-use cleaning is crucial for ensuring their reliability and extending their service life. The industry standard still relies on manual cleaning, which is inefficient, labor-intensive, and time-consuming. Furthermore, it struggles to remove dirt, impurities, and flame-retardant residues adhering to the hose's outer surface, leading to performance degradation, impacting future usability, and even shortening its lifespan.

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Example 1 like Figures 1 to 2 As shown, a fire hose cleaning device for fire protection engineering according to one embodiment of the present invention includes a cabinet 1, which integrates an unwinding mechanism, a cleaning mechanism, a guiding mechanism, and an intelligent control mechanism 101. The intelligent control mechanism 101 regulates the coordinated operation of the unwinding mechanism and the guiding mechanism to achieve automatic unwinding of the fire hose. Simultaneously, the cleaning mechanism rinses the unwinded fire hose, and the various mechanisms work together to complete a fully automatic fire hose cleaning process.

[0022] like Figure 2 , Figure 5and Figure 6 As shown, the unwinding mechanism consists of a rotary motor 2 and winding rods 3. Multiple winding rods 3 are provided, each with a slot 31. When winding the fire hose, the hose body is inserted into the slot 31, and its joint is blocked by the winding rod 3. Rotating the winding rod 3 winds the fire hose onto the rod. The rotary motor 2 is rotatably connected to a shaft 21, and the winding rods 3 are detachably connected to the shaft 21. When the shaft 21 drives the winding rods 3 to rotate, the fire hose wound on the rod unfolds, and the cleaning mechanism simultaneously washes the unfolded fire hose.

[0023] It should be noted that since the site is usually not ready for immediate cleaning after firefighting operations, the fire hose winding and storage work is done before cleaning.

[0024] like Figure 5 and Figure 6 As shown, a slot 211 is provided on the rotating shaft 21, and a mating groove 33 matching the outer diameter of the rotating shaft 21 is provided on the winding rod 3. A plug 34 matching the slot 211 is welded to the bottom wall of the mating groove 33. During assembly, the winding rod 3 is picked up and aligned with the rotating shaft 21. The winding rod 3 is then pushed horizontally towards the rotating shaft 21, and the rotating shaft 21 will enter the mating groove 33. At the same time, the plug 34 will also be inserted into the slot 211, realizing the mating of the rotating shaft 21 and the winding rod 3.

[0025] It is worth noting that the insert 34 and the slot 211 should adopt a non-circular structure to prevent the hose reel 3 from rotating relative to the shaft 21 when the fire hose is unrolled.

[0026] Preferably, the insert 34 is a regular hexagon. When the insert 34 is inserted into the slot 211, a self-locking mechanism is formed between the insert 34 and the slot 211, preventing the winding rod 3 from rotating on the rotary motor 2. At the same time, the regular hexagon shape facilitates the insertion of the insert 34.

[0027] Furthermore, to prevent the hose reel 3 from detaching from the rotary motor 2 during hose release, a locking groove 32 is provided on the hose reel 3, and a locking sleeve 23 matching the outer diameter of the hose reel 3 is fixedly connected to the rotating shaft 21. Specifically, a fixing sleeve 22 matching the rotating shaft 21 is integrally formed on the locking sleeve 23, and the fixing sleeve 22 is welded to the rotating shaft 21. A cavity 2301 is provided inside the locking sleeve 23, and an electric push rod 231 is fixedly installed inside the cavity 2301. A locking block 232 is welded to the piston rod of the electric push rod 231, and the locking block 232 penetrates the inner wall of the hose reel 3. Specifically, the winding rod 3, which is inserted into the rotary motor 2, is located inside the locking sleeve 23. At this time, the locking groove 32 and the locking block 232 are in corresponding positions. The piston rod of the electric push rod 231 extends and pushes the locking block 232 out of the cavity 2301, so that it is locked into the locking groove 32, thus fixing the winding rod 3 on the rotary motor 2 and preventing the winding rod 3 from falling off the rotary motor 2.

[0028] like Figure 2 , Figure 8 and Figure 9 As shown, the cleaning mechanism includes a water pump 4 and a cleaning cylinder 5. A water storage tank 13, connected to the water pump 4, is fixedly installed inside the cabinet 1. The water storage tank 13 contains cleaning water. A water pump 4 is welded with a water suction pipe 41 and a water delivery pipe 42. The end of the water suction pipe 41 away from the water pump 4 is welded to the water storage tank 13. The end of the water delivery pipe 42 away from the water pump 4 is welded to the cleaning cylinder 5. A first nozzle 51 is installed on the cleaning cylinder 5, and the first nozzle 51 has a spray nozzle 5101. When the water pump 4 starts, it draws water from the water storage tank 13 and sprays it out from the spray nozzle 5101.

[0029] like Figure 2 , Figure 4 and Figure 9 As shown, the guiding mechanism includes an air pump 8, which is installed inside the cabinet 1. A first air pipe 81 is welded to the air pump 8, and an air bag 82 matching the hose connector is fixedly installed at the end of the first air pipe 81 away from the air pump 8. Specifically, a slide rail 15 is welded to the cabinet 1, and a slider 151 is slidably connected to the slide rail 15. The air pump 8 is welded to the slider 151. When the slider 151 slides on the slide rail 15, it drives the air pump 8 to move within the cabinet 1.

[0030] The cleaning cylinder 5 has a water passage groove 501, and the water supply pipe 42 is connected to the water passage groove 501. The first nozzle 51 is fixedly installed on the inner wall of the cleaning cylinder 5 and is connected to the water passage groove 501. Specifically, multiple first nozzles 51 are evenly distributed in a circumferential direction inside the cleaning cylinder 5, so that water is sprayed out in a 360° range of the cleaning cylinder 5, ensuring the cleaning effect on the fire hose.

[0031] During cleaning, firstly, the hose reel 3, with the fire hose wound around it, is connected to the rotary motor 2, with the metal connector on the fire hose facing the cleaning drum 5. The slider 151 drives the air pump 8 to slide towards the cleaning drum 5, and the first air pipe 81 passes through the cleaning drum 5, with the air bladder 82 inserted into the metal connector of the fire hose. At this time, the air pump 8 supplies gas into the air bladder 82, which inflates and engages with the metal connector on the fire hose. The slider 151 then slides away from the cleaning drum 5, allowing the fire hose to pass through. During this process, the rotary motor 2 rotates to release the fire hose, and the water pump 4 draws water from the water tank 13 and injects it into the cleaning drum 5 to clean the fire hose passing through it.

[0032] Furthermore, multiple brush strips are fixedly connected to the inner wall of the cleaning cylinder 5. When cleaning the fire hose, as the fire hose moves inside the cleaning cylinder 5, the brush strips can rub against the fire hose, creating a scrubbing effect on the moving fire hose and enhancing the removal of dirt.

[0033] The brush bar includes a connecting rod 52 and bristles 53. The connecting rod 52 penetrates the inner wall of the cleaning cylinder 5 and extends into the water channel 501. The bristles 53 are adhered to the end of the connecting rod 52 away from the cleaning cylinder 5. A soft bladder 521 is heat-fused to the connecting rod 52 and is embedded in the inner wall of the cleaning cylinder 5. Specifically, when water flows in the water channel 501, it continuously impacts the end of the connecting rod 52 that extends into the water channel 501. Because the soft bladder 521 is elastic, the connecting rod 52 will tilt under the impact of the water flow. When the connecting rod 52 tilts, the impact force of the water flow naturally decreases, and it can swing back and forth under the elastic rebound of the soft bladder 521 and the impact of the water flow, thereby causing the bristles 53 to swing, which can produce a brushing effect on the fire hose, greatly improving the cleaning effect of the fire hose and cleaning away dirt and impurities on the fire hose.

[0034] Furthermore, a slope 511 is provided on the first nozzle 51, and a water nozzle 5101 is provided on the slope 511. The water nozzle 5101 on the slope 511 can spray water at an angle. The water sprayed at an angle can not only improve the flushing effect on dirt and impurities, but also continuously impact the bristles 53 and the connecting rod 52, increasing their vibration frequency and further improving the scrubbing effect on the fire hose.

[0035] In order to conserve water resources, such as Figure 2 and Figure 3 As shown, the cabinet 1 is sealed with multiple doors 11. A collection box 12 is welded inside the cabinet 1. The water pump 4 and the cleaning cylinder 5 are both installed on the collection box 12. A drain trough 121 is provided on the collection box 12. During the cleaning process, water sprayed from the cleaning cylinder 5 falls onto the collection box 12 and then into the collection box 12 through the drain trough 121, achieving the recycling and reuse of cleaning water resources and thus saving water.

[0036] Preferably, the collection tank 12 and the water storage tank 13 are seamlessly connected through a pre-set connecting pipe to form a closed-loop water circulation system. At the same time, a high-efficiency filtration system is integrated inside the collection tank 12, so that the cleaning wastewater falling into the collection tank 12 is treated by multiple filtrations and then transported back to the water storage tank 13 for recycling. This not only greatly reduces water consumption, but also ensures stable cleaning water quality and improves the energy efficiency and environmental protection of the equipment.

[0037] A booster pump and a check valve are installed on the connecting pipe between the collection tank 12 and the water storage tank 13. The booster pump provides stable water delivery power, ensuring that the filtered clean water is quickly delivered to the water storage tank 13 to meet continuous cleaning needs. The check valve effectively prevents the clean water in the water storage tank 13 from flowing back into the collection tank 12, avoiding mixing of filtered water and wastewater and ensuring the stability of the water circulation system. In addition, a drain port is provided at the bottom of the collection tank 12, which can be opened periodically to discharge large particles of impurities that have settled in the sedimentation tank, preventing the accumulation of impurities from affecting the filtration effect. A water level sensor is installed in the water storage tank 13, which can automatically add new water when the water level in the tank is lower than the preset value, ensuring the continuous and stable operation of the equipment.

[0038] The technical solutions in the above embodiments of this application have at least the following technical effects or advantages: Compared with the prior art, in this embodiment, there is no need for manual unfolding and pulling of the fire hose. The hose reel 3 with the fire hose wound on it only needs to be connected to the shaft 21 on the rotary motor 2 to automatically complete the entire process of hose unfolding, rinsing and guiding, which significantly reduces the intensity of manual labor and shortens the cleaning operation time.

[0039] Example 2 Considering that fire hoses contain a lot of water after cleaning, which is not conducive to preservation, this application proposes the following technical solution to address the above-mentioned technical problems: like Figures 2 to 4 As shown, a partition 14 is welded inside the cabinet 1, and a water-squeezing mechanism is installed on the partition 14. This mechanism consists of a cylinder 7 and a pair of electric rollers 6, one of which is fixedly connected to the piston rod end of the cylinder 7. To accommodate the movement trajectory of the fire hose and the guiding mechanism, the partition 14 has corresponding through holes 141. After the fire hose is cleaned by the cleaning cylinder 5, it passes through the through hole 141 into the water-squeezing mechanism area. At this time, the cylinder 7 starts and pushes the connected electric rollers 6 downward, so that the pair of electric rollers 6 precisely clamp the fire hose. At the same time, the two electric rollers 6 rotate synchronously in opposite directions. Through the combined action of squeezing and rolling, the residual water inside the fire hose is efficiently squeezed out, significantly reducing the water content of the hose.

[0040] It is worth noting that a pair of electric rollers 6 are arranged directly above the collection box 12. The squeezed water flows along the partition 14 to the collection box 12 and flows into the collection box 12 through the drain trough 121, realizing the recycling and reuse of the squeezed wastewater, which is in line with the water-saving design concept.

[0041] A hot air box 9 is fixedly installed inside the cabinet 1. A second air pipe 91 is welded to the hot air box 9, and a second nozzle 92 is fixedly installed at the end of the second air pipe 91 away from the hot air box 9. After the fire hose is processed by the water squeezing mechanism, the hot air box 9 is activated to generate high-temperature hot air. The hot air is delivered to the second nozzle 92 through the second air pipe 91 and sprayed directionally onto the surface of the fire hose by the second nozzle 92 to quickly dry the residual moisture. This effectively prevents the fire hose from becoming moldy and aging due to dampness after storage, thus extending the service life of the fire hose.

[0042] Example 3 To further optimize equipment usability and space utilization, reduce production costs and labor intensity, an integrated winding mechanism was added to cabinet 1 to achieve fully automated closed-loop operation of fire hose cleaning, squeezing, drying and winding, without the need for manual intervention in the subsequent storage process.

[0043] like Figures 2 to 5 As shown, the winding mechanism adopts a structural design completely identical to the unwinding mechanism. This design not only reduces the R&D and production costs of additional parts and lowers the overall manufacturing difficulty of the equipment, but also enables the interchangeability of unwinding and winding components, allowing for flexible allocation during subsequent maintenance and improving the convenience of equipment operation and maintenance. During operation, the fire hose, squeezed by the squeezing mechanism, is precisely connected to the winding mechanism under the traction of the guiding mechanism. After the hose is embedded into the slot 31 of the winding rod 3, the air bladder 82 on the guiding mechanism simultaneously deflates, separating it from the fire hose connector. The rotating shaft 21 drives the winding rod 3 to rotate at a uniform speed, achieving neat winding of the fire hose. The entire winding process requires no manual traction or arrangement, reducing the labor intensity of operators and ensuring that the wound hose is neatly arranged, facilitating direct storage or future retrieval.

[0044] Obviously, the above-described embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention also intends to include these modifications and variations.
