Description

Technical Field

[0001] The utility model relates to the technical field of road drainage, in particular to a novel urban road drainage structure. Background Art

[0002] Urban road drainage structure refers to the construction and installation of drainage systems designed to ensure that water on the road surface can be effectively removed and drained in the event of rainfall or other water sources to maintain road access and traffic safety.

[0003] However, the existing urban road drainage structure often installs drainage grilles on the upper end of the drainage ditch for drainage. Since the drainage groove spacing between the drainage grilles is relatively fixed, when encountering extreme weather such as heavy rain, the drainage volume is large, and it is often necessary to remove the drainage grilles as a whole to discharge flood water. After the drainage grilles are removed, the drainage ditch is in an open state. Due to the lack of protection of the drainage grilles and being covered by water flow, there are potential safety hazards, which increases the risk of accidents. Secondly, during normal drainage, various debris will be mixed in the water flow, causing the debris to enter the drainage ditch. These debris will accumulate at the bottom of the drainage ditch for a long time, which may cause drainage blockage and affect the drainage effect.

[0004] Therefore, we provide a new type of urban road drainage structure. Utility Model Content

[0005] The purpose of the utility model is to provide a novel urban road drainage structure to solve the problems raised in the above-mentioned background technology.

[0010] Preferably, a guide block is welded to one side of the inner grille, and the guide block is slidably installed inside the guide groove, a pulley is rotatably installed on the upper end of the inner grille away from the guide block through a short axis, and the pulley is slidably installed inside the slide groove, a threaded column is welded at the upper end of the inner grille and at the end of one side of the pulley, and the threaded column is slidably installed inside the through groove, the outer thread sleeve of the threaded column is provided with a nut seat, and a hexagonal knob is welded to the upper end of the nut seat.

[0011] Preferably, the collecting box is movably mounted on the upper end of the square frame, and handles are welded on both sides of the upper end of the collecting box.

[0012] Preferably, a filter is embedded in the filter frame, and a fixing plate is bolted on both sides of one end of the filter frame, a roller is rotatably mounted on one side of the fixing plate through a short axis, and the roller is slidably mounted on the inside of the guide rail, and a clamping plate is welded on both sides of the other end of the filter frame, and the clamping plate is slidably mounted on the inside of a limit seat, a limiting column is welded on the inner side of the clamping plate, and the limiting column slot is mounted on the inside of the limiting slot.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] 1. This new urban road drainage structure, through the setting of drainage grilles, when the drainage volume increases, the end cover plate at the upper end of the outer grille can be opened, and the inner grille can be adjusted by using the hexagonal screw and the hexagonal knob to make it adjustable. By manually turning the inner grille, the groove distance between the outer grille and the inner grille can be changed, thereby expanding the size of the drainage groove. This structure makes it unnecessary to remove the entire drainage grille when the drainage volume increases, and it is only necessary to simply adjust the position of the outer grille and the inner grille. This not only solves the problem of increased drainage volume, but also greatly reduces safety hazards.

[0015] 2. By setting up the filter frame, small debris mixed in the water flow is effectively blocked when flowing through the filter. Since the filter is in an inclined state, these blocked small debris flow into the collection box with the push of the water flow. The inclination of the filter makes it possible for small debris to not only not accumulate on the filter after being blocked, but also be quickly and smoothly transported to the collection box, thereby effectively avoiding the blockage of the water flow channel, not only improving the smoothness of the water flow, but also effectively preventing the filter from being blocked by small debris, providing a reliable guarantee for the cleanliness and smoothness of the water flow.

[0030] Working principle: First, a new urban road drainage structure is moved to the working position. In the first step, during normal drainage, water flows through the drainage grille 4 into the drainage pit 1. Large debris such as plastic leaves carried by the water flow is blocked by the drainage grille 4 and cannot enter the drainage pit 1. Only small debris will flow into the drainage pit 1 with the water flow. In the second step, when water mixed with small debris flows through the filter screen 61, the filter screen 61 will block the small debris, and the water will flow through the filter screen 61 to the slope 11, and finally flow out with the drain port 12. In the third step, since the filter screen 61 is in an inclined state, the small debris blocked by the filter screen 61 will flow into the collection box 5 with the flow of water. The collection box 5, the drainage hole on the outside can drain the water in the collection box 5. In the fourth step, when encountering disasters such as heavy rain and floods, the drainage volume increases dramatically. At this time, the end cover plate 415 on the upper end of the outer grille 41 can be opened, and the hexagonal knob 425 is screwed through the hexagonal screw. At this time, the nut seat 424 gradually disengages from the threaded engagement state with the threaded column 423, and the inner grille 42 is manually moved. At this time, the inner grille 42 slides in the slot 411 until it coincides with the outer grille 41. At this time, the drainage port 12 is enlarged. In the fifth step, the collection box 5 is cleaned regularly, the square plate 3 is manually removed, and then the collection box 5 is taken out by the handle 51 for cleaning. In this way, the use process of a new urban road drainage structure is completed.
