The upper siphon pipe 5-1 for obtaining both ends alternates work respectively, and the siphonage of siphon pipe 5-1 always exists in guarantee, accelerates
The flowing of rainwater, increases filter effect, enhances working efficiency of the invention.
Specifically, the top surface for meeting rain plate 1-1 described in the present embodiment is equipped with several lautertuns 7, lautertuns 7 can be equipped with mud
Sand etc. has the thing of preliminary filtering function to rainwater, and lautertuns 7 is seepy material.Rainwater is first fallen in lautertuns 7, lautertuns 7
Interior silt etc. can carry out preliminary filtering to lautertuns 7 is flowed out after rainwater primary filtration to rainwater, and it is right to increase the present invention
The treatment effect of rainwater.
Specifically, the mesh number of upper filter screen 5-5 described in the present embodiment is less than the mesh number of lower filter screen 5-7.Due to upper mistake
What strainer 5-5 was carried out is primary filtration, therefore be can be improved using the lesser filter screen of mesh number through speed, by upper filter screen
After the primary filtration of 5-5, the density of impurity is reduced in rainwater, therefore can carry out essence using the biggish lower filter screen 5-7 of mesh number
Thin filtering influences flowing velocity with improving filter effect, while reducing.
Finally, it should be noted that the above embodiments are merely illustrative of the technical solutions of the present invention, rather than its limitations；Although
Present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that: it still may be used
To modify the technical solutions described in the foregoing embodiments or equivalent replacement of some of the technical features；
And these are modified or replaceed, technical solution of various embodiments of the present invention that it does not separate the essence of the corresponding technical solution spirit and
Range.
