[0022] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. The embodiments of the present invention are provided for the purpose of illustration and description, and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations are obvious to those of ordinary skill in the art.

[0023] Example

[0024] See also Figure 1 to Figure 4 In this embodiment, an environmentally friendly green building drainage structure is provided, including an outlet pipe 1 and an inlet pipe 2. The inlet pipe 2 is installed at the upper end of the outlet pipe 1, and a drain port 11 is arranged on the side of the outlet pipe 1 away from the inlet pipe 2. At the same time, a fine filtering mechanism 3 is arranged in the outlet pipe 1 between the inlet pipe 2 and the drain port 11. After water enters the outlet pipe 1 from the inlet pipe 2, it will be filtered by the fine filtering mechanism 3, and the water after filtering out fine debris will be discharged from the drain port 11;

[0025] It includes a water inlet pipe 2 and a water outlet pipe 1 with the function of filtering small debris, and the water inlet pipe 2 is installed at the upper end of the water outlet pipe 1:

[0026] A drain port 11 is arranged on one side of the water outlet pipe 1 away from the water inlet pipe 2, and a fine filtering mechanism 3 is arranged in the water outlet pipe 1 between the water inlet pipe 2 and the drain port 11:

[0027] A coarse filtering mechanism 4 is provided in the water inlet pipe 2. The coarse filtering mechanism 4 can filter out large debris in the water, and then cooperate with the fine filtering mechanism 3 to filter out the debris thoroughly. At the same time, it can also divert the filtered debris to avoid excessive accumulation of debris at one side of the filtering structure, which affects the flow of water and achieves rapid drainage.

[0028] A coarse filtering mechanism 4 is provided in the water inlet pipe 2 for filtering larger debris in the water;

[0029] Specifically, the coarse filtering mechanism 4 includes a filter 41 and a collector 42, and the filter 41 and the collector 42 are detachably connected. After water enters the coarse filtering mechanism 4, the water flows out from the filter 41 and the side walls of the collector 42. After the amount of impurities gradually increases, most of the water flows out from the filter 41 into the water inlet pipe 2, while the impurities accumulate in the collector 42. After a period of time, the coarse filtering mechanism 4 is taken out from the water inlet pipe 2, and the collector 42 can be removed, and the impurities inside it can be poured out to achieve cleaning;

[0030] The filter 41 includes a limiting tube 411, the outer wall of the limiting tube 411 is fitted with the inner wall of the water inlet pipe 2, and the two are slidably connected to each other, so as to have a limiting effect. A clamping plate 412 is arranged at the top outer edge of the limiting tube 411, and the clamping plate 412 is located at the top of the water inlet pipe 2, and its outer diameter is larger than the water inlet pipe 2, so that the entire coarse filtering mechanism 4 can be hung in the water inlet pipe 2, and it is also convenient to take the filter 41 out of the water inlet pipe 2:

[0031] The bottom of the limiting tube 411 is set as a filter cartridge 413, and a plurality of through holes 414 are opened on the side wall of the filter cartridge 413. The through holes 414 can filter larger volume of debris, so that water is discharged from the through holes 414 into the water inlet pipe 2;

[0032] An external thread ring 415 is provided at the bottom of the filter cartridge 413, and the collector 42 is threadedly installed on the filter cartridge 413 through the external thread ring 415, and convenient disassembly between the collector 42 and the filter 41 is achieved through threaded connection. The collector 42 includes an internal thread ring 421, and the internal thread ring 421 is threadably adapted to the external thread ring 415. At the same time, a net bag 422 is provided at the bottom of the internal thread ring 421, and fine holes are provided on the net bag 422 for drainage.

[0033] The drainage structure in the utility model is provided with a coarse filtering mechanism 4 in the water inlet pipe 2, and a fine filtering mechanism 3 is installed in the water outlet pipe 1. The two cooperate with each other to filter out the debris thoroughly and divert the debris, thus avoiding excessive accumulation and rapid accumulation of debris in a single filtering structure, thereby affecting the drainage function.

[0034] Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field and related fields without creative work should fall within the scope of protection of the present invention. Structures, devices and operating methods not specifically described and explained in the present invention shall be implemented according to conventional means in the field unless otherwise specified and limited.
