Thus, the features defined with "first", "second", etc. may explicitly or implicitly include one or more of such features.

[0036] Please refer to Figures 1 to 7 As shown, an improved rain grate 100 of the present utility model, the rain grate 100 includes a frame body 1 and a cover plate 2, and both the frame body 1 and the cover plate 2 can be made of ductile iron material; an opening 11 is vertically penetrated through the frame body 1, and a support step 12 is formed on the side wall of the opening 11. The cover plate 2 is installed on the support step 12 and covers the opening 11. The support step 12 is used to meet the support requirement for the cover plate 2 and prevent the cover plate 2 from protruding above the frame body 1; the top surface of the frame body 1 is an arc surface that is high on both sides and low in the middle, and the cover plate 2 has an arc structure that is high on both sides and low in the middle.

[0037] By designing the top surface of the frame body 1 to be an arc surface that is high on both sides and low in the middle, and at the same time designing the cover plate 2 to have an arc structure that is high on both sides and low in the middle, in specific use, rainwater can flow quickly from both sides of the cover plate 2 to the middle, converge and drain downward, so as to achieve a better drainage effect and reduce the occurrence of water accumulation on the road surface.

[0038] In some embodiments of the present utility model, a plurality of water inlet slots 21 are arranged at intervals along the length direction of the cover plate 2 and penetrate through the cover plate 2. Each water inlet slot 21 extends from the middle to both sides along the width direction, and the water inlet slot 21 does not extend to the side walls on both sides of the cover plate 2. In this way, during the process of rainwater flowing from both sides of the cover plate 2 towards the middle and converging, it can also continuously drain downward through the water inlet slots 21, thereby achieving a better drainage effect. When the present utility model is specifically implemented, the number of the water inlet slots 21 can be set according to the size of the rainwater grate 100 and the actual drainage requirements.

[0039] In some embodiments of the present utility model, at least one communication notch 22 communicating with the water inlet slot 21 is arranged on both sides of the cover plate 2, and the communication notches 22 on both sides of the cover plate 2 are arranged staggeredly to ensure that the cover plate 2 is an integral body. When the present utility model is specifically implemented, usually 1 - 2 communication notches 22 are arranged on each side of the cover plate 2, and it is not appropriate to arrange too many communication notches 22, otherwise the strength of the entire cover plate 2 cannot be guaranteed.

[0040] By arranging communication notches 22 communicating with the water inlet slots 21 on both sides of the cover plate 2 and staggering the communication notches 22 on both sides, during specific use, the overall support strength of the cover plate 2 can be ensured, and at the same time, the communication notches 22 can be used to cause elastic deformation of the cover plate 2, so as to realize more tightly and reliably assembling the cover plate 2 with the frame body 1, and the disassembly and assembly operation of the cover plate 2 is also very convenient.

[0041] As a specific implementation manner of the present utility model, the water inlet slot 21 has a wavy structure to achieve a better drainage effect.

[0042] In some embodiments of the present utility model, an assembly block 23 is arranged at one end of the cover plate 2, and plug-in slots 24 are formed on the side walls on both sides of the assembly block 23; an assembly sink 13 is formed on the frame body 1 at a position corresponding to the assembly block 23, and plug-in protrusions 14 corresponding to each plug-in slot 24 are formed on the side wall of the assembly sink 13. The assembly block 23 is assembled with the plug-in protrusions 14 through the plug-in slots 24, so as to realize assembling one end of the cover plate 2 with one end of the frame body 1. It should be noted that the assembly block 23 and the plug-in protrusions 14 are rotatably connected, so that the cover plate 2 can be rotated during the disassembly and assembly process. As a specific implementation manner of the present utility model, two assembly blocks 23 are arranged at intervals in the middle of one end of the cover plate 2, and two assembly sinks 13 are correspondingly arranged at one end of the frame body 1.

[0043] Furthermore, an assembly latch 25 is provided at the bottom of the other end of the cover plate 2. An assembly slot 15 is formed on the side wall of the opening 11 at a position corresponding to the assembly latch 25, and the assembly slot 15 is located below the support step 12. The assembly latch 25 is engaged in the assembly slot 15, so as to realize the clamping connection between the other end of the cover plate 2 and the other end of the frame body 1. An operation notch 26 is formed at the top of the other end of the cover plate 2 to facilitate using the operation notch 26 to pry the cover plate 2 to generate elastic deformation. As a specific embodiment of the present invention, two assembly latches 25 are spaced apart at the bottom of the other end of the cover plate 2, and two assembly slots 15 are correspondingly provided on the side wall of the opening 11.

[0048] The utility model is provided with a sand box 4 in the frame body 1, and a drain pipe insertion hole 41 is arranged through the bottom of the sand box 4. When in specific use, a drain pipe can be installed by using the drain pipe insertion hole 41, and the water entering the sand box 4 is drained away by the drain pipe, while the sediment remains at the bottom of the sand box 4, so that the sewer can be prevented from being blocked due to sediment accumulation. At the same time, during the specific use process, personnel can be arranged to clean the sand box 4 regularly, and the sand box 4 is detachably installed in the frame body 1, which is convenient for actual cleaning operation.

[0049] Furthermore, a plurality of support sinking grooves 121 are sunken on the step surface of the support step 12. A support block 42 is arranged at the upper end of the sand box 4 corresponding to each support sinking groove 121. The sand box 4 is detachably supported on the support sinking groove 121 through the support block 42, which can not only meet the support requirement for the sand box 4, but also facilitate the disassembly of the sand box 4. As a specific implementation manner of the utility model, the frame body 1, the cover plate 2 and the sand box 4 are all in a rectangular structure, and support blocks 42 are arranged on four sides of the sand box 4. Support sinking grooves 121 are formed on the step surface of the support step 12 corresponding to each support block 42.
