Description

Technical Field

[0001] This utility model relates to a pull-out grate, belonging to the field of grate technology. Background Technology

[0002] The road drainage system is a key design element to ensure the stability and durability of the road structure. Its core function is to efficiently guide surface runoff, control the groundwater level, and drain water that has seeped into the various structural layers of the road, thereby maintaining the mechanical properties of the subgrade and improving the service life of the pavement.

[0003] As a crucial component of road drainage systems, storm drain grates employ a porous mesh structure and are installed along the roadside carriageway. During actual operation, organic residues (such as fallen leaves) and solid waste carried by surface runoff easily accumulate on or inside the grates, leading to reduced drainage efficiency. Traditional maintenance methods require manual cleaning using specialized tools to pry open the grates, necessitating increased cleaning frequency, especially during the flood season. However, when the grates are submerged, water pressure significantly increases the difficulty of opening them, and if the disassembled grates are placed upright on the road surface, they not only obstruct traffic but may also cause accidents, posing a safety hazard. Utility Model Content

[0004] This utility model provides a pull-out grate to solve the problems of existing rain grate that are difficult to open due to excessive water pressure when flooded, and the open grate standing on the road, becoming an obstacle, hindering traffic and creating a safety hazard.

[0005] This utility model is achieved through the following technical solution:

[0031] like Figures 1 to 6As shown, this application provides a pull-out grate that covers a rainwater inlet or drain outlet for surface drainage. The pull-out grate 100 includes an outer frame 1 and a grate surface 2. The outer frame 1 has a C-shaped frame structure with an opening at one end. The grate surface 2 has a rectangular frame structure and is installed in the outer frame 1. The outer frame 1 provides support for the grate surface 2.

[0032] like Figure 3 As shown, in some embodiments, the outer frame 1 includes crossbeams 11, longitudinal beams 12, and grooves 13. Two crossbeams 11 are cuboid structures, located on either side of the outer frame 1. One longitudinal beam 12 is also a cuboid structure, located between the crossbeams 11, perpendicular to the crossbeams 11. Both ends of the longitudinal beam 12 are connected to the two crossbeams 11 respectively. The longitudinal beam 12 and the crossbeams 11 can be an integral structure, connected by welding, forming an internally hollow outer frame 1. Grooves 13 are disposed within the crossbeams 11, with the openings of the grooves 13 all facing inwards towards the outer frame 1. The grooves 13 penetrate the crossbeams 11, with the openings of the grooves 13 on the two crossbeams 11 facing opposite directions. The grate surface 2 is connected to the outer frame 1 by fitting into the grooves 13.

[0033] like Figure 4 As shown, in some embodiments, the grate 2 includes a frame 21, a grid 22, protrusions 23, and holes 24. The frame 21 is a rectangular frame structure. Multiple grids 22 are evenly arranged within the frame 21 to form the grate 2, which filters rainwater containing leaves, garbage, and other debris, preventing blockage of the sewer. The protrusions 23 are located on both sides of the frame 21. The shape of the protrusions 23 matches the grooves 13, and the protrusions 23 connect with the grooves 13, allowing the grate 2 to fit within the outer frame 1, restricting the direction of movement of the grate 2 so that it can only slide within the grooves 13. By controlling the sliding of the grate 2 within the grooves 13, the grate 2 can be opened or closed. The holes 24 are provided on the frame 21 and are through holes, facilitating the pulling of the grate 2 when opening or closing.

[0034] like Figure 5 and Figure 6 As shown, in some embodiments, the outer frame 1 and the grate surface 2 are combined to form a grate 100, which is installed between two flat stones 4, with its top surface flush with the flat stones 4. A base 5 is provided on one side of the flat stone 4, and a walkway 6 and a side stone 3 are provided above the base 5, with the side stone 3 perpendicularly abutting against the flat stone 4. A groove is provided inside the base 5. When the drain outlet is blocked and debris needs to be cleared, the grate surface 2 is pushed towards the walkway 6 using the hole 24, placing the grate surface 2 into the groove of the base 5. After the debris is cleared, the grate surface 2 is pulled out along the groove 13 through the hole 24 to close the drain outlet.

[0035] Optionally, the cross-section of the groove 13 is rectangular.

[0036] Optionally, the crossbeam 11 and the longitudinal beam 12 are flush with the top surface of the grate 2.

[0037] Optionally, the height of the protrusion 23 should not be greater than the depth of the groove 13, and the direction in which the protrusion 23 is parallel to the longitudinal beam 12 is the height direction.

[0038] Optionally, the top surface of the grate 2 is flush with the top surface of the base 5.

[0039] Optionally, the grate 100 is made of a rigid material. Preferably, the grate 100 is made of cast iron, which has high strength, is corrosion-resistant, and is not easily damaged by rainwater immersion, thus extending the service life of the grate 100.

[0040] The working principle of this utility model is as follows: The outer frame 1 is an integral structure. The grate 2 is connected to the outer frame 1 by a protrusion 23 engaging with a groove 13 in the outer frame 1. The protrusion 23 is installed in the groove 13 and can slide within it. This pull-out grate is pre-assembled as a single unit before leaving the factory. During use, the grate 100 is installed between two side stones, and the grate 2 is connected to the outer frame 1 by the protrusion 23. The grille 22 on the grate 2 can filter leaves, garbage, and other debris. When it needs to be opened, simply pull the hole 24 to separate the grate 2 from the outer frame 1, and push the grate 2 towards the sidewalk 6 until it enters the groove in the base 5. Opening is not affected by water pressure and does not require large opening tools, enabling rapid opening and closing of the grate 100. This facilitates quick cleaning of debris, accelerates drainage efficiency, and facilitates maintenance of the grate 100. At the same time, by retracting the grate 2 into the base 5 under the sidewalk 6, no obstacle will be formed, ensuring the safety of the road.

[0041] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0042] The above embodiments only illustrate several implementation methods of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the invention patent. It should be noted that those skilled in the art can make several modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model.
