Problems solved by technology

However, as the water level continues to rise, smaller debris can easily flow out from the gaps between the ribs, making it impossible to filter the debris thoroughly
In addition, fixing multiple stepped ribs inside the frame can help drain water, but when large objects fall into it, it is easy to cause blockage inside the frame and affect normal drainage

Embodiment Construction

[0011] figure 1 The movable filter water grate shown is composed of a water grate body (1), a large filter box (2) and a small filter box (3). The block hinge (5) forms a movable one. The length and width of the big filter box (2) are slightly smaller than the length and width of the sewer, and the height of the big filter box (2) is placed above the sewer pipe, making it easy to install and take out.

[0012] There is a projection (6) with a short top and a long bottom on the corresponding symmetrical position on the four walls of the large filter box (2). The size of the projection (6) is mainly determined according to the volume of the small filter box (3). The projection ( 6) The long part can place the small filter box (3), and the small part of the protrusion (6) can play the role of fixing the small filter box (3). The position of the projection (6) is placed in the middle part of the four walls of the large filter box (2), so that there is enough space to store sundr...

Abstract

The invention relates to a movable filtering water strainer, which comprises a water strainer body (1), a large filter box (2) and a small filter box (3), wherein two hinges (5) are arranged at corresponding positions of one side of each of the water strainer body (1) and the large filter box (2) to form a movable whole, so that overall installation and withdrawal are facilitated. The small filter box (3) is put on bumps (6) in four walls of the large filter box (2); and the small filter box (3) can be taken out. A round water outlet (7) is formed in the bottom of the large filter box (2) and two lines of strip-shaped water outlets (4) are formed in the middle and upper parts of four walls of the small filter box (3), so that secondary filtration is carried out while impurities are filtered for the first time, daily normal drainage is not affected, and cleaning and maintenance of a worker are facilitated.

Description

technical field [0001] The invention relates to a movable grate device for filtering water. It includes a water grate body, a large filter box and a small filter box. The water grate body and the large filter box are movably connected, and a small filter box is arranged in the large filter box. Background technique [0002] At present, the water grate widely used in the society is a hollowed-out cover device installed directly at the entrance of the sewer, which can only prevent large objects from falling in, but cannot block small debris, which will flow with the waste water. It flows into the sewer together, which often causes blockage of the sewer pipe, and even leads to serious problems of road accumulation in rainy weather. In the prior art, the Chinese utility model CN ​​201420318994 relates to an anti-blocking rainwater grate, which includes a frame body, and a plurality of ribs are evenly fixed in the frame body, and the ribs are in the shape of multi-level steps, f...
