[0004] However, the fire water filter has the following disadvantages:

[0005] (1) The water filter body and the filter cover are connected by screws. When the filter cover needs to be disassembled and cleaned, the screws need to be loosened first for disassembly, and then tightened to fix after cleaning, which is a cumbersome operation;

[0006] (2) Only a single water inlet is provided. When the filter cover is clogged by debris, the water inlet efficiency will become low, or even unable to supply water. Temporary cleaning of the filter cover requires interruption of the fire water supply, affecting firefighting use. Utility Model Content

Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] See also Figures 1 to 4The utility model provides a technical solution: a fire water filter, including a water filter body 1, both ends of the bottom surface of the water filter body 1 are welded with connecting plates 2, one side of the connecting plate 2 is welded with a sealing mechanism 3, the surface of the sealing mechanism 3 is threadedly connected to a flange 4, one side of the flange 4 is welded with an inlet pipe 5, through the arrangement of two groups of inlet pipes 5, when pumping water, when the inlet pipe 5 at one end is blocked by debris and affects the water inlet rate, the inlet pipe 5 at the other end is placed in the water body to continue pumping water, and the blocked inlet pipe 5 can be quickly cleaned and continued to be used. By arranging two groups of inlet pipes 5, it can be achieved that even when the inlet pipe 5 is blocked, a stable water supply can still be achieved, and the blocked water filter net 11 can be cleaned to avoid affecting the progress of fire fighting. A valve 6 is fixedly installed in the middle of the surface of the inlet pipe 5, and a limiting hole is provided on the edge of the surface of the inlet pipe 5. The internal sliding connection of the positioning hole is a limiting mechanism 7, and a blocking piece 8 is welded on one side of the surface of the water inlet pipe 5. An opening and closing mechanism 9 is fixedly arranged on one side of the blocking piece 8. Through the setting of the opening and closing mechanism 9 and the limiting mechanism 7, the opening and closing ring 902 is pulled to the left, and then the connecting head 10 is inserted into the water inlet pipe 5, and the opening and closing ring 902 is loosened. The spring 901 rebounds the opening and closing ring 902 to reset it, so that the limiting ball head column 702 is clamped in the trapezoidal limiting groove, thereby achieving the effect of quickly plugging the connecting head 10 and the water filter net 11 into the water inlet pipe 5. When disassembling the water filter net 11, the opening and closing ring 902 is pulled and the connecting head 10 is pulled outward. The limiting ball head column 702 is lifted up along the edge of the trapezoidal limiting groove, which is convenient for disassembly and easy to clean the water filter net 11. The connecting head 10 is clamped at one end of the water inlet pipe 5, and the water filter net 11 is welded on one side of the connecting head 10.

[0029] The limiting mechanism 7 includes a sliding block 701 slidably connected to the inside of the limiting hole, and a limiting ball head column 702 is fixedly arranged on one side of the sliding block 701. The setting of the limiting mechanism 7 facilitates the fixing of the connecting head 10.

[0030] The opening and closing mechanism 9 includes a spring 901 fixedly arranged on one side of the blocking plate 8, and an opening and closing ring 902 is fixedly arranged on one side of the spring 901. Through the setting of the opening and closing mechanism 9, the limiting ball head column 702 is convenient for opening, and the limiting ball head column 702 can be fixed when closing.

[0031] A trapezoidal limiting groove is provided on the surface of the connector 10, which is matched with the limiting ball head column 702. Through the setting of the trapezoidal limiting groove, when the connector 10 is pulled out, the limiting ball head column 702 is lifted up along the waist position of the trapezoidal limiting groove.

[0032] The sealing mechanism 3 includes a threaded tube 301 welded to one side of the connecting plate 2. A sealing ring 302 is sleeved on the surface of the threaded tube 301. The sealing ring 302 is made of rubber. Through the setting of the sealing mechanism 3, the connection between the connecting plate 2 and the flange plate 4 is sealed.

[0033] The surface of the connection plate 2 is provided with connection holes in a circular array around it, and the internal threads of the connection holes are penetrated by connection bolts 12. The connection bolts 12 are arranged to connect the connection plate 2 and the flange plate 4.

One end of the connecting bolt 12 is threadedly connected with a nut 13, and the setting of the nut 13 plays a role in locking the connecting bolt 12.

[0035] In the utility model, the working steps of the device are as follows:

[0036] Step 1: Put the sealing ring 302 on the threaded pipe 301, and then screw the water inlet pipe 5 to connect the flange 4 with the connecting plate 2, and then screw the connecting bolts 12 to connect the connecting plate 2 and the flange 4, and screw the nuts 13 to lock them. The whole can be disassembled for maintenance;

[0037] The second step: pull the opening and closing ring 902 to the left, and then insert the connector 10 into the water inlet pipe 5. At this time, the connector 10 pushes up the limiting ball column 702. After being inserted into place, the limiting ball column 702 falls and is stuck in the trapezoidal limiting groove on the surface of the connector 10. Loosen the opening and closing ring 902, and the spring 901 rebounds the opening and closing ring 902 to reset it. The opening and closing ring 902 closes the top of the limiting ball column 702 so that the limiting ball column 702 is clamped in the trapezoidal limiting groove, and the connector 10 and the water filter 11 are quickly plugged into the water inlet pipe 5;

[0038] Step 3: When pumping water, when the water inlet pipe 5 at one end is blocked by debris and affects the water inlet rate, the water inlet pipe 5 at the other end is placed in the water body to continue pumping water, and the blocked water inlet pipe 5 can be quickly cleaned and then continued to be used. By setting two groups of water inlet pipes 5, it can be achieved that even if the water inlet pipe 5 is blocked, the water supply can still be stable, and the blocked water filter 11 can be cleaned;
