[0034] Specifically, the mounting frame 1 is used to be embedded in the position where the rain grate 2 needs to be installed. The rain grate 2 is used to discharge rainwater. A support frame 3 is fixedly connected to the left side of the mounting frame 1 to support the rotation of the baffle 4. The baffle 4 is used to prevent debris from entering the drainage pipe. The support frame 2 5 is arranged on the right side of the mounting frame 1 to protect the internal connection of the support. A connecting rod 6 is arranged on the right side of the multiple baffles 4 to allow the multiple baffles 4 to rotate at the same time. A turntable 7 is arranged on the right side of the connecting rod 6 to rotate the turntable 7 to rotate the multiple baffles 4. A worm gear 8 is arranged on the right side of the turntable 7 to rotate the worm 9 to drive the worm gear 8 to rotate, thereby driving the turntable 7 to rotate. A handle 10 is arranged on the top of the worm 9 to better rotate the worm 9, and is arranged inside the rain grate 2 so that there is no protrusion on the surface of the rain grate 2 to ensure the safety of pedestrians.

[0035] Reference Figure 4 - Figure 5The stabilizing component includes a plurality of sliding rods 12, and the plurality of sliding rods 12 are slidably connected to the inside of the mounting frame 1. Two card slots 11 are provided on the left and right sides of the rain grate 2. The plurality of sliding rods 12 are respectively clamped in the plurality of card slots 11. The ends of the plurality of sliding rods 12 away from the card slots 11 are slidably connected to fixed rods 13. The outer circumferences of the plurality of fixed rods 13 are sleeved with springs 14. The outer circumferences of the plurality of sliding rods 12 are rotatably connected to connecting rods 15.

The plurality of springs 14 are respectively fixedly connected to the ends of the plurality of sliding rods 12 away from the card slots 11. The other ends of the plurality of springs 14 are fixedly connected to the inside of the mounting frame 1. The tops of the two limiting frames 17 are fixedly connected to handles 18, and the handles 18 are arranged inside the mounting frame 1.

[0036] Specifically, a sliding rod 12 is arranged inside the mounting frame 1, which is used to insert the sliding rod 12 into the slot 11 of the rain grate 2 to improve the stability of the rain grate 2. A fixed rod 13 is fixed inside the mounting frame 1, which is used to provide sliding of the sliding rod 12. A spring 14 is sleeved on the outer periphery of the fixed rod 13 to reset the movement of the sliding rod 12. A connecting rod 15 is arranged on the outer periphery of the sliding rod 12 to connect the sliding rod 12 and the pull rod 16, so that when the pull rod 16 is pulled, the sliding rod 12 is driven to leave the slot 11.

The handle 18 is used for the operator to better pull the pull rod 16, and is arranged inside the mounting frame 1 so that there is no protrusion on the surface of the mounting frame 1 to ensure the safety of pedestrians.

[0037] Working principle: When the baffle 4 is in a normal state, rainwater drives debris into the rain grate 2 and is blocked by the baffle 4 to prevent clogging of the drain pipe. When the rainwater is heavy, the handle 10 can be turned to drive the worm 9 to rotate. When the worm 9 rotates, it drives the worm wheel 8 to rotate, thereby driving the turntable 7 to rotate, and driving multiple baffles 4 to rotate through the connecting rod 6, so that the gap between the baffles 4 becomes larger, thereby increasing the drainage volume.

[0038] When the spring 14 releases its tension, the sliding rod 12 will be stuck in the slot 11 of the rain grate 2, so that the rain grate 2 is stably fixed on the mounting frame 1 to ensure the safety of pedestrians. When the rain grate 2 needs to be opened to clean up the debris on the baffle 4, the handle 18 is pulled to drive the pull rod 16 to move, and the pull rod 16 makes the sliding rod 12 leave the slot 11 through the connecting rod 15, and the rain grate 2 can be removed. When installing the rain grate 2, first pull the handle 18 to make the sliding rod 12 enter the inside of the mounting frame 1, place the rain grate 2 on the mounting frame 1, and release the force of the handle 18. The spring 14 releases its tension to re-insert the sliding rod 12 into the slot 11 to complete the installation.

[0039] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
