Figure 1 It shows a first structural schematic diagram of a sewer outlet drainage protection cover in an embodiment of the utility model. Figure 2 A second structural schematic diagram of the sewer outlet drainage protection cover in an embodiment of the utility model is shown.
[0024] The sewer outlet drainage protective cover includes a first cage frame 100, a second cage frame 200 and a warning column 300, the first cage frame 100 is fixedly arranged below the second cage frame 200, and the warning column 300 is fixedly arranged above the second cage frame 200; the diameter of the second cage frame 200 is larger than the diameter of the first cage frame 100, and the first cage frame 100 is used to be inserted into the sewer outlet.
[0025] In the sewer outlet drainage protective cover of the utility model, the first cage frame 100 is used to be inserted into the sewer outlet, and the second cage frame 200 covers the sewer outlet, so that it will not fall into the sewer as a whole, which can ensure smooth drainage and will not be washed away by the water flow, thereby effectively preventing pedestrians from accidentally falling into the sewer; the warning column 300 stands above the second cage frame 200, which is relatively high and conspicuous, and can warn people to avoid the location of the sewer outlet.
[0026] In some specific embodiments, see Figure 1 or Figure 2 The first cage frame 100 and the second cage frame 200 are coaxial, so that the sewer outlet drainage protective cover can be stably inserted in the sewer outlet and is not easily knocked down by the water flow; the warning column 300 is located at the geometric center of the upper side of the second cage frame 200, ensuring the visibility and effect of the warning column 300, so that it can more effectively attract people's attention.
[0027] In some specific embodiments, see Figure 1 or Figure 2 The first cage skeleton 100 includes a first circle portion 110, a second circle portion 120 and a plurality of first vertical rods 130, one end of the plurality of first vertical rods 130 is fixedly connected to the first circle portion 110, and the other end of the plurality of first vertical rods 130 is fixedly connected to the second circle portion 120; the second cage skeleton 200 includes a third circle portion 210, a fourth circle portion 220, a plurality of first cross rods 230, a plurality of second cross rods 240 and a plurality of second vertical rods 250, one end of the plurality of second vertical rods 250 is fixedly connected to the third circle portion 210, and the other end of the plurality of second vertical rods 250 is fixedly connected to the fourth circle portion 220; one end of the plurality of first cross rods 230 is fixedly connected to the second circle portion 120, and the other end of the plurality of first cross rods 230 is fixedly connected to the third circle portion 210; one end of the plurality of second cross rods 240 is fixedly connected to the fourth circle portion 220, and the other end of the plurality of second cross rods 240 is fixedly connected to the warning column 300. The first cage frame 100 and the second cage frame 200 have good stability, can withstand the impact of water flow, and have a large gap to ensure smooth drainage. At the same time, they can protect the sewer opening to prevent pedestrians from accidentally falling into the sewer.
[0028] For details, please refer to Figure 1 or Figure 2, the first circular portion 110 and the second circular portion 120 are of equal size, the third circular portion 210 and the fourth circular portion 220 are of equal size, the diameter of the second circular portion 120 is smaller than the diameter of the third circular portion 210, and the second circular portion 120 and the third circular portion 210 are coplanar and co-centered. The first cage frame 100 and the second cage frame 200 are both cylindrical structures. The first cage frame 100 of the cylindrical structure can be stably inserted into the sewer outlet and has good matching performance with the sewer outlet; the second cage frame 200 of the cylindrical structure can stably cover the sewer outlet; the first cage frame 100 and the second cage frame 200 cooperate with each other, while ensuring drainage, also ensuring the overall stability of the sewer outlet drainage protective cover, and will not fall into the sewer as a whole, nor will it be washed away by the water flow.
[0029] In some specific embodiments, see Figure 1 , there are 4 first vertical rods 130, and the 4 first vertical rods 130 are evenly spaced; there are 10 first cross bars 230, and the 10 first cross bars 230 are evenly spaced; there are 10 second cross bars 240, and the 10 second cross bars 240 are evenly spaced; there are 10 second vertical rods 250, and the 10 second vertical rods 250 are evenly spaced. Such a cage frame gap of the sewer outlet drainage protective cover is relatively large, and drainage is smoother.
