Description

Technical Field

[0001] This utility model relates to the field of fire hose reel technology, specifically a fire hose reel. Background Technology

[0002] Fire hose reels consist of valves, inlet pipes, spokes, support frames, rocker arms, hoses, and spray guns. They typically use water, dry powder, or foam as extinguishing agents and are fire extinguishing devices that can quickly deploy the hose to spray the extinguishing agent. They are generally installed in indoor fire hydrant boxes and are a new type of fixed indoor fire-fighting device.

[0003] Chinese Patent Publication No. CN221950498U discloses a wear-resistant and impact-resistant fire hose reel. This invention utilizes a wear-resistant coating to prevent wear on the reel body during prolonged use. A first corrosion-resistant layer provides excellent corrosion resistance, preventing corrosion from external substances and extending service life. A high-temperature resistant layer protects against high temperatures during fires, ensuring the reel's lifespan is not affected. First and second high-strength layers provide good strength, preventing deformation under impact and improving impact resistance. A buffer pad further reduces the impact force on the reel, enhancing its overall impact resistance.

[0004] However, the sprinkler heads in the fire hose reels of the above-mentioned scheme lack a filter device. Since fire-fighting water sources are wide-ranging, they may contain a large number of large particulate impurities, such as mud, sand, and rust particles. Unfiltered water rushes towards the sprinkler head under pressure. These large particulate impurities are very likely to accumulate in the narrow channels inside the sprinkler head, gradually clogging the nozzles and internal flow channels. This results in a significant reduction in the water flow rate and a sharp drop in the spray pressure, ultimately seriously affecting the fire-fighting effect and failing to meet the fire-fighting requirements. This greatly weakens the effectiveness and reliability of the fire-fighting system during fire suppression.

[0005] Therefore, it is necessary to invent a fire hose reel. Utility Model Content

[0006] The purpose of this invention is to provide a fire hose reel to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a fire hose reel, comprising a reel body, a fire hose wound around the outer side of the reel body, a connecting pipe connected to the end of the fire hose, a nozzle threaded into the end of the connecting pipe, a double-sided magnetic baffle rotatably mounted on one side of the nozzle, a connecting ring fixedly mounted on the other side of the nozzle, the connecting ring being threaded into one end of the connecting pipe, an outer ring fixedly mounted on the inner wall of the connecting ring, a filter screen fixedly mounted inside the outer ring, and a scraper rotatably mounted on one side of the filter screen.

[0008] Preferably, the top of the nozzle is fixedly provided with symmetrically distributed trapezoidal blocks, a rotating shaft is rotatably provided between two trapezoidal blocks, a rotating block is fixedly provided on the outside of the rotating shaft, and the double-sided magnetic baffle is fixedly connected to the rotating block.

[0009] Preferably, a magnet three is fixedly provided at the bottom of the nozzle, and the magnet three is magnetically attracted to the double-sided magnetic baffle two.

[0010] Preferably, a magnet is fixedly provided on the top of the rotating block, and a water inlet pipe is provided on one side of the disc.

[0011] Preferably, the outer side of the connecting ring is threaded, and the inner wall of one end of the connecting pipe is provided with a threaded groove.

[0012] Preferably, a connecting shaft is provided inside the filter screen, and the connecting shaft is fixedly connected to the scraper.

[0013] Preferably, both ends of the scraper are provided with grooves, a pulley is rotatably provided between the two side walls of the grooves, and an annular groove is provided on one side of the outer ring, with the pulley slidably installed in the annular groove.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] 1. When the nozzle is not in use, the double-sided magnetic baffle two can be magnetically attracted to the magnet three, thus blocking the nozzle and preventing debris from entering and causing blockage. When water flows through the connecting pipe, it will first pass through the filter screen to block large particles of impurities and prevent the nozzle from being blocked. Finally, it will spray out from the nozzle. When water passes through the filter screen, the scraper will rotate to scrape and clean the surface of the filter screen, removing impurities and dirt attached to the filter screen, thereby cleaning the filter screen and preventing it from being blocked.

[0016] 2. When it is necessary to thoroughly clean the nozzle and filter, the nozzle can be rotated out of the connecting pipe, thereby pulling the connecting ring and filter out of the connecting pipe to achieve a thorough cleaning of the nozzle and filter, ensuring that the nozzle can output water normally when needed for effective fire extinguishing.

[0027] Furthermore, a magnet 1411 is fixedly provided on the top of the rotating block 143, and a water inlet pipe 11 is provided on one side of the disc body 1.

[0028] Furthermore, the outer side of the connecting ring 15 is provided with threads, and the inner wall of one end of the connecting pipe 13 is provided with a threaded groove.

[0029] Furthermore, a connecting shaft 163 is provided inside the filter screen 161, and the connecting shaft 163 is fixedly connected to the scraper 164.

[0030] Furthermore, both ends of the scraper 164 are provided with grooves 165, and pulleys 167 are rotatably provided between the two side walls of the grooves 165. An annular groove 166 is provided on one side of the outer ring 16, and the pulleys 167 are slidably installed in the annular groove 166.

[0031] Working principle: When the nozzle 14 is not in use, the double-sided magnetic baffle 144 and the magnet 146 can attract each other, thereby blocking the nozzle 14 and preventing debris from entering the nozzle 14 and causing blockage.

[0032] When the nozzle 14 is needed, the double-sided magnetic baffle 144 can be rotated upwards to separate from the magnet 146, thereby making the double-sided magnetic baffle 144 and the magnet 1411 magnetically attract each other to fix the double-sided magnetic baffle 144. When water passes through the connecting pipe 13, it will first be filtered by the filter screen 161 to block large particles of impurities and prevent the nozzle 14 from being blocked.
