Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] See also Figure 1-6 The utility model provides a technical solution: a water supply and drainage filter device, including a shell 1, which is fixedly connected to a water inlet pipe 4 and a water outlet pipe 6 respectively. The water source that needs to be filtered can be transported through the water inlet pipe 4 and the water outlet pipe 6. A rotating rod 8 is rotatably connected to the shell 1, and the outer surfaces of the rotating rod 8 are fixedly connected to two filter screens 10 and two baffles 11 respectively. The rotating rod 8 can drive the filter screen plates 10 and the baffles 11 to rotate. The outer surface of each filter screen plate 10 and the outer surface of each baffle 11 are in contact with the inner wall of the shell 1. The two baffles 11 cooperate with the shell 1 to form a closed chamber for filtering water source, and one of the filter screen plates 10 is located inside the closed chamber. A limiting structure is provided on the shell 1, which can fix the rotating rod 8. A through hole 17 is opened on the shell 1, and the through hole 17 can facilitate the maintenance of the filter screen plate 10 by the staff.

[0024] Among them, the limiting structure includes a ratchet 12 fixedly connected to the rotating rod 8, and the upper end surface of the shell 1 is fixedly connected to the rotating shaft 13. The rotating shaft 13 is rotatably connected to a pawl 14 matching the ratchet 12. The ratchet 12 can be limited by the pawl 14. The ratchet 12 can be limited by the pawl 14 so that it can only rotate to one side. The direction in which it can move is the water inlet direction, so it will not rotate due to the impact of water flow.

[0025] Among them, the upper end surface of the shell 1 is fixedly connected to a protective shell 16, and the upper end surface of the protective shell 16 is provided with a through hole. The rotating rod 8 is arranged inside the through hole. The inside of the protective shell 16 is fixedly connected to a spring 15, and the other end of the spring 15 is fixedly connected to the pawl 14. The spring 15 can push the pawl 14 to contact the ratchet 12 more firmly to prevent it from loosening.

[0026] Among them, a sealing plate 18 is movably installed inside the through-portion 17, and a fixing plate 19 is fixedly connected to the sealing plate 18. The fixing plate 19 has two first threaded holes 20, and the inner wall of each first threaded hole 20 is threadedly connected with a fixing bolt 21. The upper end surface of the outer shell 1 has two second threaded holes corresponding to the first threaded holes 20, and the bottom end of each fixing bolt 21 extends to the inside of the second threaded hole and is threadedly connected to the inner wall of the second threaded hole. The sealing plate 18 can be firmly installed by the fixing bolt 21.

[0027] Among them, a group of holes 23 are opened on the lower end surface of the sealing plate 18, and a group of plug rods 22 matching the holes 23 are fixedly connected to the inside of the through opening 17. By using the plug rods 22 and the holes 23 in combination, the bottom of the sealing plate 18 can be limited and fixed, making its installation more stable and reliable.

[0028] The rotating rod 8 is fixedly connected to a rotating disk 9, which can facilitate the rotation of the rotating rod 8.

[0029] The lower end surface of the housing 1 is fixedly connected to a mounting plate 2 , on which a group of mounting holes 3 are formed. The housing 1 can be fixed by using the mounting plate 2 and the mounting holes 3 .

[0030] Among them, the other end of the water inlet pipe 4 is fixedly connected to the first pipe joint 5, and the other end of the water outlet pipe 6 is fixedly connected to the second pipe joint 7. The first pipe joint 5 and the second pipe joint 7 can be used to conveniently connect the device to external equipment.

[0031] Working principle: When in use, the device must first be installed in the use position, and the water inlet pipe 4 and the water outlet pipe 6 are connected to the outside through the first pipe joint 5 and the second pipe joint 7 respectively. Inside the shell 1, the internal space of the shell 1 can be divided into two parts by two baffles 11, namely the water filtration area located on one side of the water inlet pipe 4, and the maintenance area located on the side of the through-port 17. There is a filter screen 10 in each of the two areas. The water source transported through the water inlet pipe 4 can enter the water filtration area for filtration, and can be discharged to the outside through the water outlet pipe 6 after filtration; the staff can maintain the filter screen 10 on the other side through the through-port 17. When the filter screen 10 needs to be adjusted for alternate use, the rotating rod 8 can be rotated through the turntable 9. The rotating rod 8 can drive the filter screen 10 and the baffle 11 to rotate, thereby changing the use position.

[0032] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
