[0030] like Figures 1-8As shown, the fire water tank filtration device includes a base 1, on which a water tank 2 is fixedly installed. An inlet pipe 7 and an outlet pipe 8 are fixedly installed at both ends of the water tank 2. A disinfection unit is fixedly installed on the water tank 2, connecting the outlet pipe 8 and the water tank 2. Filtering units are fixedly installed inside both the inlet pipe 7 and the outlet pipe 8. The inlet pipe 7 connects to an external water supply device, and the outlet pipe 8 connects to an external fire-fighting device. During operation, when the external water supply device supplies water to the water tank 2 through the inlet pipe 7, impurities in the water flow are filtered by the filtering units, and the filtered water enters the water tank. Inside the water tank 2, the water enters the external fire-fighting device through the outlet pipe 8, and is filtered again by the filter unit inside the outlet pipe 8 to ensure that the water entering the external fire-fighting device is clean. When not in operation, the fire-fighting water is stored in the water tank 2, and the fire-fighting water in the water tank 2 is sterilized and disinfected by the disinfection unit to prevent the biofilm formed by the growth of microorganisms during the storage of fire-fighting water from entering the external fire-fighting device and affecting its service life. It also prevents the biofilm formed by microorganisms from clogging the filter unit inside the outlet pipe 8.

[0031] like Figure 2 , Figure 4 , Figure 5As shown, the filtration unit includes a filter screen mechanism 303 and a support frame 304. Rotating components are fixedly installed in both the inlet pipe 7 and the outlet pipe 8. The filter screen mechanism 303 is slidably installed in the inlet pipe 7 and the outlet pipe 8, and is fixedly installed on the rotating components. The support frame 304 is fixedly installed in the inlet pipe 7 and the outlet pipe 8. A buffer component is fixedly installed on the support frame 304, and a first cleaning brush mechanism 308 is fixedly installed on the buffer component. The first cleaning brush mechanism 308 is slidably connected to the filter screen mechanism 303. When the external water supply device delivers fire-fighting water to the water tank 2 through the inlet pipe 7, impurities in the fire-fighting water are filtered by the filter screen mechanism 303. The filtered fire-fighting water enters the water tank 2. When the fire-fighting water in the water tank 2 is discharged to the external fire-fighting device through the outlet pipe 8, it is filtered again by the filter screen mechanism 303 in the outlet pipe 8, effectively preventing impurities in the fire-fighting water. Impurities entering the external fire protection system can affect its service life. When the filter mechanism 303 filters impurities in the fire-fighting water, the rotating component drives the filter mechanism 303 to rotate. The rotation of the filter mechanism 303 reduces the accumulation of impurities on the filter mechanism 303, and the centrifugal force during rotation causes the filtered impurities to fall off the filter mechanism 303. At the same time, the support frame 304 and the buffer component support the first cleaning brush mechanism 308. The buffer component ensures that the first cleaning brush mechanism 308 is in continuous contact with the filter mechanism 303. The first cleaning brush mechanism 308 cleans the filtered impurities on the filter mechanism 303, causing the filtered impurities to fall off the filter mechanism 303, ensuring the cleanliness of the filter mechanism 303, reducing the clogging of the filter mechanism 303, and enabling the filter mechanism 303 to better filter the fire-fighting water, ensuring the filtration effect and water flow efficiency.

[0032] like Figure 1 , Figure 3 , Figures 6-8As shown, the disinfection unit includes a water pump 401, a disinfection tank 402, and a first control valve 404. The water pump 401 is fixedly installed on the base 1. The disinfection tank 402 and the first control valve 404 are both fixedly installed on the water tank 2. The water pump 401 is connected to the disinfection tank 402 and the outlet pipe 8. The outlet end of the water pump 401 is connected to the disinfection tank 402, and the inlet end of the water pump 401 is connected to the outlet pipe 8. The first control valve 404 is connected to both the disinfection tank 402 and the water tank 2. The disinfection tank 402 is equipped with a sterilization and disinfection mechanism 403 and a cleaning unit. When the fire-fighting water in the water tank 2 is not in use, the fire-fighting water is stored in the water tank 2. The fire-fighting water in the water tank 2 is drawn out by the water pump 401 through the outlet pipe 8 and transported to the disinfection tank 402. The fire-fighting water entering the disinfection tank 402 is disinfected by the sterilization and disinfection mechanism 403. After sterilization and disinfection, the fire-fighting water flows back to the water tank 2 for storage through the first control valve 404. This prevents the growth of algae and other microorganisms in the fire-fighting water during storage, effectively reducing the clogging of the filter mechanism 303 caused by the biofilm formed by the growth of microorganisms, ensuring the normal filtration efficiency of the filter mechanism 303, and preventing algae and other microorganisms from entering the external fire-fighting equipment and affecting its service life. At the same time, the sterilization and disinfection mechanism 403 is cleaned by the cleaning unit to prevent impurities in the fire-fighting water from accumulating on the sterilization and disinfection mechanism 403, ensuring the sterilization and disinfection effect of the sterilization and disinfection mechanism 403 on the fire-fighting water.

[0033] like Figure 1 , Figure 2 , Figure 4 , Figure 7 , Figure 8 As shown, the rotating assembly includes a first motor 301 and a rotating shaft 302. The first motor 301 is fixedly installed on the side of the water inlet pipe 7 and the water outlet pipe 8. The rotating shaft 302 is rotatably installed inside the water inlet pipe 7 and the water outlet pipe 8. The rotating shaft 302 is fixedly connected to the output shaft of the first motor 301 and the filter screen mechanism 303. The first motor 301 drives the rotating shaft 302 to rotate, and the rotating shaft 302 drives the filter screen mechanism 303 to rotate.

[0034] like Figure 5 As shown, the buffer assembly includes a sleeve 305, which is fixedly mounted on a support frame 304. A spring 306 is fixedly installed inside the sleeve 305, and a slide rod 307 is slidably mounted on the sleeve 305. The slide rod 307 is fixedly connected to the first cleaning brush mechanism 308. The spring 306 provides elastic support to the slide rod 307, ensuring that the first cleaning brush mechanism 308 is always in contact with the filter screen mechanism 303. This allows the first cleaning brush mechanism 308 to continuously and effectively clean the filter screen mechanism 303, ensuring the cleaning effect of the first cleaning brush mechanism 308.

[0035] like Figure 5As shown, the slide bar 307 is square. The square design prevents the slide bar 307 from rotating during movement, improves the stability of the slide bar 307, and allows the slide bar 307 to better support the first cleaning brush mechanism 308.

[0036] like Figure 2 , Figure 4 As shown, a collection pipe 9 is fixedly installed at the lower end of both the inlet pipe 7 and the outlet pipe 8. A second control valve 10 is fixedly installed at the lower end of the collection pipe 9. The collection pipe 9 is located directly below the first cleaning brush mechanism 308. When the first cleaning brush mechanism 308 cleans the filter screen mechanism 303, the debris that falls off is collected at the lower end of the inlet pipe 7 and the outlet pipe 8 and enters the collection pipe 9. The second control valve 10 controls the opening and closing of the collection pipe 9, thereby exporting the debris collected in the collection pipe 9 and improving the convenience and efficiency of cleaning debris.

[0037] like Figure 1 , Figure 2 , Figure 4 As shown, flow sensors 6 are fixedly installed in the inlet pipe 7, outlet pipe 8, and water tank 2. The flow sensors 6 are located on both sides of the filter mechanism 303. When the fire-fighting water flows in the inlet pipe 7 and outlet pipe 8, the flow sensors 6 detect the water flow velocity on both sides of the filter mechanism 303. The flow velocity on both sides of the filter mechanism 303 determines whether the filter mechanism 303 is blocked. When the filter mechanism 303 is blocked, it can be dealt with in a timely manner.

[0038] like Figure 1 , Figure 3 , Figure 6 , Figure 8 As shown, the cleaning unit includes a second motor 501 and a lead screw 502. The second motor 501 is fixedly installed on the side of the disinfection tank 402, and the lead screw 502 is rotatably installed inside the disinfection tank 402. The lead screw 502 is fixedly connected to the output shaft of the second motor 501. A movable part 503 is threadedly connected to the lead screw 502, and a second cleaning brush mechanism 504 is fixedly installed on the movable part 503. The second cleaning brush mechanism 504 is slidably connected to the sterilization and disinfection mechanism 403. When circulating and sterilizing the fire-fighting water stored in the water tank 2, the second motor 501 drives the lead screw 502 to rotate, and the lead screw 502 drives the second cleaning brush mechanism 504 to move through the movable part 503. The second cleaning brush mechanism 504 cleans the sterilization and disinfection mechanism 403 to prevent impurities in the water flow from accumulating on the sterilization and disinfection mechanism 403, thus ensuring the sterilization and disinfection effect of the sterilization and disinfection mechanism 403 on the fire-fighting water.

[0039] Working principle: such as Figure 1 , Figure 2 , Figure 4 , Figure 5 , Figure 7, Figure 8 As shown, the external water supply device supplies water to the water tank 2 through the inlet pipe 7. The fire water flowing through the inlet pipe 7 is filtered by the filter screen mechanism 303. The filtered fire water enters the water tank 2. The fire water in the water tank 2 enters the external fire protection device through the outlet pipe 8. The fire water flowing through the outlet pipe 8 is filtered again by the filter screen mechanism 303 to ensure that the fire water entering the external fire protection device is clean.

[0040] like Figure 1 , Figure 2 , Figure 4 , Figure 5 , Figure 7 , Figure 8 As shown, when the fire-fighting water is filtered by the filter mechanism 303, the first motor 301 drives the rotating shaft 302 to rotate, and the rotating shaft 302 drives the filter mechanism 303 to rotate. The rotating filter mechanism 303 reduces the accumulation of impurities on the filter mechanism 303, and the centrifugal force during rotation causes the impurities filtered on the filter mechanism 303 to fall off. At the same time, the spring 306 provides elastic support to the slide rod 307, so that the first cleaning brush mechanism 308 is always in contact with the filter mechanism 303, and the first cleaning brush mechanism 308 cleans the filter mechanism 303.

[0041] like Figure 2 , Figure 4 As shown, the debris that falls off is collected at the lower ends of the inlet pipe 7 and the outlet pipe 8 and enters the debris collection pipe 9. The second control valve 10 controls the opening and closing of the debris collection pipe 9, thereby removing the debris collected in the debris collection pipe 9.

[0042] like Figure 1 , Figure 2 , Figure 4 As shown, when fire-fighting water flows in the inlet pipe 7 and the outlet pipe 8, the flow sensor 6 detects the water flow velocity on both sides of the filter mechanism 303. The flow velocity on both sides of the filter mechanism 303 determines whether the filter mechanism 303 is blocked. If the filter mechanism 303 is blocked, it can be dealt with in time.

[0043] like Figure 1 , Figure 3 , Figures 6-8 As shown, when the fire-fighting water in water tank 2 is not in use, the fire-fighting water is stored in water tank 2. The fire-fighting water in water tank 2 is pumped out through water outlet pipe 8 by water pump 401 and transported to disinfection tank 402. The fire-fighting water entering the disinfection tank 402 is disinfected by sterilization and disinfection mechanism 403. After sterilization and disinfection, the fire-fighting water flows back to water tank 2 through the first control valve 404 for storage, so as to prevent the growth of algae and other microorganisms in the stored fire-fighting water.

[0044] At the same time, such as Figure 1 , Figure 3 , Figure 6 , Figure 8 As shown, when circulating and sterilizing the fire-fighting water stored in the water tank 2, the second motor 501 drives the lead screw 502 to rotate. The lead screw 502 drives the second cleaning brush mechanism 504 to move through the movable part 503. The second cleaning brush mechanism 504 cleans the sterilization and disinfection mechanism 403 to prevent impurities in the water flow from accumulating on the sterilization and disinfection mechanism 403, thus ensuring the sterilization and disinfection effect of the sterilization and disinfection mechanism 403 on the fire-fighting water.
