[0002] Rainwater grates are welded from flat steel and twisted square steel or flat steel and flat steel. Rainwater grates have the advantages of beautiful appearance, optimal drainage, high strength, multiple specifications and low cost, so steel grating rainwater grates are usually used. With the development of technology, resin or plastic is used with steel bars as reinforcement and inorganic fillers to form a new composite water grate. The advantage is that the weight is lighter than the cast iron water grate and the cost is low. The disadvantage is that the strength is not as high as the cast iron water grate.

Under the action of the filter plate 4, impurities can be effectively blocked to prevent impurities from entering the interior of the pipe, achieving a double screening and blocking effect, thereby achieving an anti-blocking effect.

[0024] In this embodiment, preferably, the moving mechanism includes a first trapezoidal plate 6, a second trapezoidal plate 7, a support rod 8 and a reset mechanism, the first trapezoidal plate 6 is movably arranged inside the movable groove 5, the second trapezoidal plate 7 is arranged on one side of the first trapezoidal plate 6, the inclined surface angles of the first trapezoidal plate 6 and the second trapezoidal plate 7 are consistent, the bottom end of the first trapezoidal plate 6 is fixedly provided with a support rod 8, and the bottom end of the second trapezoidal plate 7 is provided with a reset mechanism;

[0025] Through the above scheme, under the movement of the first trapezoidal plate 6, the second trapezoidal plate 7 can be driven to extend outward as a whole, so that support points are formed on both sides of the device, thereby supporting the filter plate 4 as a whole. When the first trapezoidal plate 6 moves upward, the second trapezoidal plate 7 is moved back to the inside of the movable groove 5, and the fixing effect of the filter plate 4 is cancelled. The filter plate 4 can be disassembled and replaced. At this time, all impurities can be discharged and cleaned, and it is convenient to clean the surface of the filter plate 4, keep the surface of the filter plate 4 clean and tidy, and maintain the filtering effect of the filter plate 4;

[0026] In this embodiment, preferably, the bottom end of the support rod 8 passes through the movable slot 5 on the mounting plate 3, and a handle 9 is fixedly provided at one end of the support rod 8 located outside the mounting plate 3;

When the first trapezoidal plate 6 moves to the bottom position, under the action of the spring 16, the moving block 13 can be moved to one side along the surface of the guide rod 15, thereby driving the second trapezoidal plate 7 to move back. When the second trapezoidal plate 7 is completely moved back to the inside of the movable groove 5, the filter plate 4 will fall directly without the support of the second trapezoidal plate. This setting can effectively disassemble the filter plate 4 as a whole, facilitate the effective cleaning of impurities inside the equipment, and at the same time, the surface of the filter plate 4 can be cleaned regularly to keep the filtering effect of the filter plate 4 stable.
