[0025] It also includes a support frame, the bottom of the cover body is adapted to be placed on the support frame, and the support frame is used to connect with the foundation to support the cover body; one end of the cover body is correspondingly provided with a convex head, and the convex head is provided with a first through-hole penetrating through the two wall surfaces, and the support frame is correspondingly provided with a groove, and the groove is correspondingly provided with a second through-hole, and the convex head is placed in the groove and rotated through the second rotating shaft; it should be noted that the support frame is one of the commonly used components in the overflow manhole cover, which can be directly purchased and used on the market, and its connection and cooperation with the cover body are also conventional, and the specific details are not repeated;

[0026] In the overflow well grate, the top surface and side walls of the cover body are provided with a plurality of first strip-shaped drainage holes; a cover plate is installed on the outer side of each side wall of the cover body, and a plurality of second strip-shaped drainage holes are provided on the cover plate, and the second drainage holes are oriented differently from the first drainage holes on the corresponding side wall of the cover body, and the first drainage holes and the second drainage holes are cross-stacked in space to form a grid-like arrangement of holes, which can maintain normal drainage and effectively block large pieces of debris so that the debris stays on the outside;

[0027] In addition, the cover is movably installed on the outside of the side wall of the cover body and can be adjusted to flip outward. When it is necessary to clear the blockage, the cover can be flipped outward to quickly remove the blocking debris adhering to the outside and maintain smooth drainage. In addition, the cover body itself has corresponding barriers on the inside to prevent large pieces of external debris from entering the drainage system.

[0028] Furthermore, the bottom of the cover 200 is rotatably mounted on the cover body 100, and the cover is rotated and flipped around the bottom. On the one hand, it can be conveniently adjusted from the top and turned outward; on the other hand, it can limit the debris adhering to it, and can also press the debris when flipped into place to prevent the debris from easily moving to the cover body and causing secondary blockage.

[0029] Furthermore, if Figure 3 , Figure 4 As shown, the cover body 100 includes a prism portion 120, and a flange 130 connected to the bottom of the side wall of the prism portion 120; a group of relatively arranged support blocks 140 are fixedly arranged at the center positions of the four sides of the flange 130, and a first rotating shaft 300 is rotatably penetrated between the two support blocks 140; the bottom of the cover plate 200 is correspondingly provided with an outwardly protruding column 220, and a circular hole 230 is provided along the axis of the column 220, and the diameter of the circular hole is adapted to the diameter of the first rotating shaft, and the first rotating shaft 300 is penetrated at the circular hole 230, and the column 220 is rotatably arranged between the two support blocks 140; a simple rotational matching connection is adopted, which can facilitate processing and production and also reduce costs;

[0030] Furthermore, if the old cover needs to be improved, the support block can be welded and fixed to the flange, and the required cover plate can be installed accordingly; if large-scale customization is adopted, the support block and the cover can be required to be an integrally formed structure, which reduces the subsequent welding and installation steps and facilitates practical use.

[0031] Furthermore, the first rotating shaft 300 is close to the connection between the flange 130 and the prism portion 120; the wall surface of the cover plate 200 close to the prism portion 120 is tangentially connected to the outer wall of the column 220; the cover plate 200 is rotatably installed between the two support blocks 140 via the column 220, the column 220 is rotatably supported on the top surface of the flange 130, and the cover plate 200 can swing to fit the side wall of the cover body 100; this structural design can make the cover plate better fit the side wall of the cover body, on the one hand, it can make the whole more compact and prevent it from being easily loosened or turned over; on the other hand, it can reduce the distance between the two, improve the effect of blocking debris, prevent flexible debris such as plastic bags and dead leaves from entering the internal range of the distance, and avoid such debris from easily entering the drainage system from the long first drainage hole.

[0032] Furthermore, strip openings 240 are provided on both sides of the connection between the cover plate 200 and the column bar 220. The position of the strip openings 240 corresponds to the position of the support block 140, and the bottom end of the strip openings 240 is open; the length of the strip openings 240 is greater than the length of the support block 140, and the width of the strip openings 240 is greater than the width of the support block 140; this structural design can expand the flipping range of the cover plate, prevent interference and collision between the cover plate and the support block, ensure that the cover plate can be flipped to a flat state, and have a pressing and limiting effect on the debris adhered to the cover plate, so that the debris is pressed to the bottom, preventing the debris from easily falling off, and avoiding the debris from adhering to the outer wall of the cover body again to cause secondary blockage; and, in actual use, one or more cover plates can be selected to be flipped open according to actual conditions to meet the corresponding drainage effect and prevent external debris from quickly clogging the drainage holes on the cover body.

[0033] Furthermore, the position of the strip opening 140 corresponds to the position of part of the first drainage hole 110 to achieve conduction. This part is close to the top surface of the flange, which means it is close to the ground and can be used as a drainage part to expand the drainage range, especially for drainage at the bottom position, reducing external water accumulation.

[0034] The present invention is described by preferred embodiments, and those skilled in the art will appreciate that various changes or equivalent substitutions may be made to these features and embodiments without departing from the spirit and scope of the present invention. The present invention is not limited to the specific embodiments disclosed herein, and other embodiments falling within the claims of this application are within the scope of protection of the present invention.
