[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. 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.

[0020] See also Figures 1 to 5 The utility model provides a technical solution: a drainage anti-blocking structure, including a drainage pipe 1, an opening 2 is opened on one side of the drainage pipe 1, and guide rods 22 are slidably inserted at the four corners of the opening 2. Filters 21 are slidably sleeved on multiple guide rods 22. Multiple filter screens 21 are provided, and the multiple filter screens 21 are arranged and distributed along the axial direction of the guide rods 22. The multiple filter screens 21 can be provided with different apertures to filter different debris.

[0021] A first airbag 23 is installed on one side of the filter screen 21 and is sleeved on the guide rod 22. The setting of the first airbag 23 plays a role of elastic buffering. A second airbag 24 is installed between the two filter screens 21 and is sleeved on the guide rod 22. The setting of the second airbag 24 separates the two filter screens 21 on the one hand, and plays a role of elastic buffering on the other hand.

[0022] A mounting plate 3 is slidably inserted at the opening of the opening 2, and the mounting plate 3 is a "T"-shaped plate structure. Fixed blocks 4 are fixed on both sides of the mounting plate 3 on the drain pipe 1, and a plug hole 41 is provided on one side of the fixing block 4. The end of the mounting plate 3 is abutted against the side of the filter screen 21, and an integral structure is formed between the filter screen 21 and the guide rod 22, so that the filter screen 21 moves axially along the guide rod 22 under the limiting action of the mounting plate 3.

[0023] The mounting plate 3 is provided with a mounting and fixing assembly, which includes a mounting seat 5. A groove is provided on one side of the mounting seat 5. A mounting block 51 is fixed at the opening of the groove by screws. A movable plug rod 52 is slidably inserted on the mounting block 51, and the end of the movable plug rod 52 matches with the socket 41.

[0024] A limiting block 53 is fixed on the movable plug rod 52, and a supporting spring 54 is sleeved on the movable plug rod 52. An elastic abutment structure is formed between the supporting spring 54 and the limiting block 53, so that the end of the movable plug rod 52 is inserted into the socket 41, thereby realizing fixed installation of the mounting plate 3 on the drain pipe 1.

[0025] During actual use, multiple filter screens 21 move due to the pressure of the water flow. Due to the restoring elastic force of the first airbag 23 and the second airbag 24, multiple filter screens 21 move in the opposite direction of the water flow pressure, thus forming a shaking between the multiple filter screens 21, making it difficult for some debris or pollutants to be adsorbed on the filter screen 21, thereby increasing the drainage function of the filter screen 21; when disassembly is required, pull the movable plug rods 52 on both sides to make the ends of the movable plug rods 52 away from the socket 41, and then take out the mounting plate 3, the guide rod 22 and the filter screen 21 in turn, which is convenient for timely replacement or cleaning, and is conducive to the reuse of the drainage and anti-clogging structure filter screen 21.

[0026] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
