Description

Technical Field

[0001] The utility model relates to the technical field of rainwater grate devices, in particular to a rainwater grate which is convenient to clean. Background Art

[0002] Rainwater grates are an important facility used in road drainage systems. They are usually installed in road ditches, rainwater outlets, etc. to filter rainwater and prevent debris from entering the drainage pipes.

[0003] Traditional rainwater grates have some significant drawbacks in practical use. For one thing, they are easily clogged by impurities or silt. When a blockage occurs, the entire grate must be removed for unclogging, which is inconvenient and increases the difficulty and workload of cleaning. Furthermore, when conducting water quality testing, sampling is often performed at the location of the rainwater grate. However, traditional rainwater grates are more cumbersome to sample, and some even require the removal of bolts to remove the grate, which is not only time-consuming but can also cause damage to the grate and surrounding facilities.

[0028] The present invention will be described in further detail below with reference to the accompanying drawings.

[0029] Combined with attachment Figure 1 To the attached Figure 7 , a rain grate that is easy to clean, comprises a rectangular frame 1 and an edge cover 19 fixed to the upper end of the rectangular frame 1, the edge cover 19 is provided with a sampling port 13 for water quality monitoring and sampling, and the sampling port 13 is hingedly provided with an end cover 14, a grate body 2 is fixedly provided at the bottom edge of the interior of the rectangular frame 1, and a number of evenly distributed leakage holes 3 are provided on the grate body 2, a filter plate 4 is movably provided at the upper end of the interior of the rectangular frame 1, and a lifting plate 6 is movably connected to the interior of the rectangular frame 1 through a spring assembly 5, and a slope 15 inclined toward the center is provided around the upper end surface of the grate body 2, the size of the lifting plate 6 is smaller than the size of the grate body 2, and a number of conical protrusions 7 corresponding to the leakage holes 3 for cleaning the blockage of the leakage holes 3 are fixed on the bottom surface of the lifting plate 6.

[0030] In this embodiment, as a preferred technical solution, the spring assembly 5 includes a groove 8 provided on the left and right side walls inside the rectangular frame 1, a guide rod 9 is fixed inside the groove 8, a slider 10 is slidably provided on the guide rod 9, a spring 11 is sleeved on the guide rod 9 and located below the slider 10, and a Z-shaped connecting rod 12 is fixedly connected between the side of the slider 10 and the lifting plate 6.

[0031] In this embodiment, as a preferred technical solution, a boss 16 is fixedly provided at the upper end of the inner wall of the rectangular frame 1, and the filter plate 4 is movably mounted on the boss 16. The filter plate 4 is provided with a plurality of strip holes 17 distributed in a matrix, and a circular hole 18 is provided in the center of the filter plate 4 to facilitate pressing down the lifting plate 6.

[0032] The working principle of the conveniently cleaned rain grate of the present invention is as follows: When a blockage needs to be cleared, a tool such as a steel pipe or rebar is inserted through the circular hole 18 in the center of the filter plate 4 to press the lifting plate 6 downward. At this point, the spring assembly 5 connected to the lifting plate 6 begins to function. The slider 10 in the spring assembly 5 slides on the guide rod 9, compressing the spring 11. The conical protrusions 7 on the bottom surface of the lifting plate 6 correspond one-to-one with the leakage holes 3 in the grate body 2. When the lifting plate 6 is pressed downward, the conical protrusions 7 penetrate the leakage holes 3, pushing out impurities or silt stuck in the leakage holes 3, thereby clearing the blockage. When the pressure stops, the lifting plate returns to its original position under the action of the spring.

[0033] The working process of the utility model of a convenient and clean rainwater grate is as follows:

[0034] 1. Installation: The grate body 2 is fixed to the bottom edge of the rectangular frame 1, and the filter plate 4 is movably mounted on the boss 16 at the upper end of the inner wall of the rectangular frame 1, so that the filter plate 4 can be easily disassembled and cleaned to maintain its good filtering effect. The strip holes 17 on the filter plate 4 can preliminarily filter larger particles of impurities and prevent them from entering the drainage system. The lifting plate 6 is connected by the spring assembly 5, so that the lifting plate 6 can move up and down when subjected to external force to achieve the cleaning of the leakage hole 3. The edge cover 19 is provided with a sampling port 13 to facilitate water quality testing and sampling. The sampling port 13 is hinged with an end cover 14, which remains closed when sampling is not in progress to prevent debris from entering.

[0035] 2. Daily Observation: During daily use, regularly monitor the drainage of the grate. If the drainage rate slows significantly or water accumulates, this may indicate a blockage. You can also monitor the accumulation of impurities on the filter plate 4. Excessive accumulation of impurities on the filter plate 4 may affect drainage performance and require prompt cleaning.

[0036] 3. Clearing the Blockage: When you determine the grate is clogged, insert a tool, such as a steel pipe or rebar, through the circular hole 18 in the center of the filter plate 4 and press down firmly on the lifting plate 6. The lifting plate 6 descends under the pressure, and the slider 10 in the spring assembly 5 slides upward on the guide rod 9, compressing the spring 11. As the lifting plate 6 descends, the conical protrusion 7 on its underside penetrates the leaking hole 3, pushing out any impurities or silt that may be blocking it. Repeat this pressing operation several times, depending on the severity of the blockage, to ensure that the leaking hole 3 is completely unobstructed. When clearing is complete, remove the tool from the circular hole 18, and the lifting plate 6 returns to its initial position under the restoring force of the spring 11.

[0037] 4. Water Quality Testing and Sampling: When water quality testing is required, open the end cap 14 of the sampling port 13 on the edge cover 19. No need to disassemble the entire rainwater grate; water quality monitoring and sampling can be performed directly from the sampling port 13. After sampling, close the end cap 14 to prevent debris from entering the sampling port 13.

[0038] The above description of the present invention and its embodiments is non-limiting. The drawings show only one embodiment of the present invention, and the actual structure is not limited thereto. In short, if a person skilled in the art is inspired by the above, and does not deviate from the purpose of the present invention, without inventive design, a structure and embodiment similar to the technical solution should fall within the scope of protection of the present invention.
