Description

Technical Field

[0001] The present application relates to the field of drainage structures, and in particular to a municipal engineering drainage structure. Background Art

[0002] Municipal roads reach all parts of the city, providing transportation and pedestrian use within the city, facilitating residents' lives, work, cultural and entertainment activities, and connecting with roads outside the city to carry external traffic. Urban road drainage refers to the measures taken to remove precipitation from the surface of urban roads.

[0003] For example, the utility model patent with patent announcement number CN218643504U discloses a municipal engineering drainage structure, including a frame, a first rain leaking plate is hinged inside the frame, a second rain leaking plate is hinged on one side of the first rain leaking plate, one end of the second rain leaking plate is embedded in the surface of the frame, the surface of the second rain leaking plate is symmetrically connected with guide wheels through a rotating axis, guide grooves are symmetrically opened inside the frame, and the ends of the guide wheels that are away from each other are both arranged in the guide grooves opened inside the frame; an anti-blocking mechanism is installed on the bottom surface of the frame.

[0004] When pedestrians walk on the drainage structure of the municipal engineering project, their mobile phones and keys often fall into the drainage ditch from the drainage structure. It is very inconvenient for pedestrians to pick up the fallen mobile phones and keys without professional tools, which needs to be improved. Utility Model Content

[0005] In order to improve the problem that mobile phones and keys often fall into the drainage ditch from the drainage structure when pedestrians walk on the drainage structure, the present application provides a municipal engineering drainage structure.

[0006] This application provides a municipal engineering drainage structure, which adopts the following technical solution:

[0007] A municipal engineering drainage structure includes a road body and a cover plate, wherein a water leakage plate is provided on the road body, and a trough is also provided on the road body, wherein the water leakage plate is located in the trough, and an extension plate is provided on the inner side wall of the trough, and the cover plate is located above the extension plate and covers the water leakage plate, and a groove is provided on the outer side wall of the cover plate close to the water leakage plate, and a plurality of through holes are also circumferentially provided on the cover plate, wherein the through holes are connected to the groove, and a connecting rod is provided on the cover plate, and the connecting rod is lifted and slid on the water leakage plate, and a floating block is provided on the connecting rod, and the floating block is located below the water leakage plate.

[0008] By adopting the above technical solution, when it is not raining, the cover plate abuts against the extension plate under the action of gravity, and the cover plate covers the leaky plate to prevent mobile phones and keys from falling into the drainage ditch through the leaky plate when pedestrians walk on the drainage structure. When it rains, rainwater enters the space between the cover plate and the leaky plate through the through holes, and then flows into the drainage ditch through the leaky plate to achieve drainage. If the rainfall is heavy, the water level in the drainage ditch rises, and the floating block drives the cover plate upward under the action of buoyancy to increase the drainage volume and speed up the drainage of water on the road surface. At the same time, the cover plate is lifted to facilitate pedestrians to observe and avoid the place, thereby reducing the situation where pedestrians step on empty air at this place and reducing safety hazards.

[0009] Optionally, a plurality of partition bars are provided on the cover plate, and the plurality of partition bars are distributed at intervals along the outer circumference of the groove, and the partition bars are lifted and slid on the extension plate.

[0010] By adopting the above technical solution, a dividing strip is set. When the floating block drives the cover plate upward under the action of buoyancy, it also drives the dividing strip upward. The accumulated water enters between the cover plate and the leaking plate through the gap between adjacent dividing strips. The dividing strip can intercept and filter debris and garbage such as leaves carried in the accumulated water, thereby reducing the possibility of the leaking plate being blocked, which is beneficial to improving the drainage effect.

[0011] Optionally, elastic sheets are provided on opposite sides of the dividing strips, the elastic sheets are located between adjacent dividing strips, and limiting grooves are provided on the extension plate, and the elastic sheets are lifted and slid in the limiting grooves.

[0012] By adopting the above technical solution, the impact of water squeezes the elastic sheet to cause the elastic sheet to deform, and then enters between the cover plate and the leaking plate through the gap between the elastic sheets on adjacent dividing strips. When the water level drops subsequently, the cover plate moves downward under the action of gravity, driving the dividing strips and the elastic sheet to move downward, and the elastic sheet is abutted against the inner wall of the limiting groove to cause the elastic sheet to reset, thereby pushing out the debris blocked between the adjacent elastic sheets, reducing the situation where the cover plate is stuck by the debris between the dividing strips.

[0013] Optionally, the water leakage plate is provided with a plurality of guide surfaces, the plurality of guide surfaces are located above the water leakage plate and are distributed circumferentially, and the guide surfaces are inclined downward and inward, a mounting hole is opened on the cover plate, a baffle is hinged on the cover plate, the baffle is used to cover the mounting hole, and a positioning piece for positioning is provided on the baffle.

[0014] By adopting the above technical solution, some small particles of debris pass through the adjacent elastic sheets and fall between the cover plate and the leaking plate and are intercepted by the leaking plate. Under the continuous flushing of the water flow, the debris on the leaking plate is gathered along the guide surface to the middle of the leaking plate, so as to reduce the area of ​​the leaking plate blocked by debris and extend the drainage effect of the leaking plate. The baffle can also be opened regularly to clean the debris on the leaking plate.

[0015] In summary, the present application includes at least one of the following beneficial technical effects:

[0016] 1. When it is not raining, the cover plate abuts against the extension plate under the action of gravity, and the cover plate covers the leaking plate to prevent mobile phones and keys from falling into the gutter through the leaking plate when pedestrians walk on the drainage structure. When it rains, rainwater enters the gutter through the through hole to achieve drainage. If the rainfall is heavy, the water level in the gutter rises, and the floating block drives the cover plate upward under the action of buoyancy to increase the drainage volume and speed up the emptying of water on the road surface. At the same time, the cover plate is lifted so that pedestrians can observe and avoid the place, reducing the situation where pedestrians step on empty space at the place, reducing safety hazards;

[0017] 2. By setting up the separation strip, the debris and garbage such as leaves carried in the accumulated water can be intercepted and filtered, which reduces the blockage of the leaking plate and is conducive to improving the drainage effect;

[0018] 3. By setting the elastic sheet and the limiting groove, the impact of water squeezes the elastic sheet to make it deform, and then enters between the cover plate and the leaking plate through the gap between the elastic sheets on the adjacent dividing strips. When the water level drops subsequently, the cover plate moves downward under the action of gravity, driving the dividing strip and the elastic sheet to move downward, and the elastic sheet is abutted against the inner wall of the limiting groove to cause the elastic sheet to reset, thereby pushing out the debris blocked between the adjacent elastic sheets, reducing the situation where the cover plate is stuck by the debris between the dividing strips.

The cover plate 2 is located above the extension plate 5 and covers the leaking plate 3, and the cover plate 2 abuts against the extension plate 5. A groove 21 is opened on the outer wall of the cover plate 2 close to the leaking plate 3, and a plurality of through holes 22 are opened on the outer wall of the cover plate 2. The plurality of through holes 22 are evenly spaced around the outer periphery of the cover plate 2 in the circumferential direction, and the through holes 22 are connected with the grooves 21. Two connecting rods 6 are fixed on the cover plate 2, and the two connecting rods 6 are both located in the grooves 21 and are spaced apart, and the two connecting rods 6 are vertically penetrated through the leaking plate 3 and lifted and slid on the leaking plate 3. A floating block 7 is fixed to the lower end of each connecting rod 6, and the floating block 7 is located below the leaking plate 3.

[0026] See also Figure 2 and Figure 3 A plurality of dividing strips 8 are fixed to the lower end of the cover plate 2, and the plurality of dividing strips 8 are evenly spaced around the outer circumference of the groove 21, and each dividing strip 8 is vertically penetrated by an extension plate 5 and is lifted and slid on the extension plate 5, and elastic sheets 9 are fixed on the opposite sides of each dividing strip 8, and each elastic sheet 9 is located between two adjacent dividing strips 8. A limiting groove 51 is provided on the extension plate 5, and the number and position of the limiting grooves 51 correspond one-to-one to the number and position of the elastic sheets 9, and each elastic sheet 9 is lifted and slid in the corresponding limiting groove 51. In this embodiment, the elastic sheet 9 is made of rubber.

[0027] See also Figure 2 and Figure 3 A mounting hole 23 is provided on the upper end surface of the cover plate 2, and the mounting hole 23 vertically penetrates the cover plate 2. A baffle 10 is hinged on the cover plate 2, and the hinge axis of the baffle 10 is horizontally arranged. The baffle 10 is used to cover the mounting hole 23.

[0029] The implementation principle of a municipal engineering drainage structure in the embodiment of the present application is:

[0030] When it is not raining, the cover plate 2 abuts against the extension plate 5 under the action of gravity. The cover plate 2 covers the leaking plate 3, which can prevent mobile phones and keys from falling into the drainage ditch through the leaking plate 3 when pedestrians walk on the drainage structure.

[0031] When it rains, rainwater enters the space between the cover plate 2 and the leaking plate 3 through the through hole 22, and then is discharged into the drainage ditch through the leaking plate 3 to achieve drainage. If the rainfall is heavy, the water level in the drainage ditch rises, and the floating block 7 drives the cover plate 2 and several dividing strips 8 to move upward under the action of buoyancy to increase the drainage volume and speed up the drainage of water on the road surface. At this time, the impact of water squeezes the elastic sheet 9 to deform the elastic sheet 9, and then enters between the cover plate 2 and the leaking plate 3 through the gap between the elastic sheets 9 on adjacent dividing strips 8. When the water level drops subsequently, the cover plate 2 moves downward under the action of gravity, driving the dividing strips 8 and the elastic sheet 9 to move downward, and the inner wall of the limiting groove 51 abuts against the elastic sheet 9 to cause the elastic sheet 9 to reset, thereby pushing out the debris blocked between the adjacent elastic sheets 9, reducing the situation where the cover plate 2 is stuck by the debris between the dividing strips 8.

[0032] On the other hand, the cover plate 2 is lifted up to facilitate pedestrians to observe and avoid the area, thereby reducing the situation where pedestrians step on empty space and reducing safety hazards.

[0033] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
