Description

Technical Field

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

[0002] Road drainage includes pavement drainage and roadside drainage. It is a facility that is used to drain rainwater, snowwater, urban wastewater, groundwater and lower the groundwater level from the road surface and the ground in combination with road engineering. It is an important part of road engineering and is also a part of drainage or flood control engineering when it comes to drainage systems or flood control.

[0003] In the existing technology, conventional road drainage structures mostly use drainage manhole covers. Due to rainy weather, the leaves of green plants fall, which may cause the drainage manhole covers to be blocked, resulting in waterlogging on the road, or a large amount of garbage flows into the drainage pipes, causing garbage to accumulate in the drainage pipes, resulting in accumulation, which in turn leads to serious waterlogging on the road and inability to drain properly.

[0019] See also Figure 1-Figure 3 The utility model discloses a road drainage structure for flood prevention, including a box body 1, a drainage cover 2 is placed on the upper surface of the box body 1, and rectangular drainage holes 3 are evenly opened on the drainage cover 2.

A placing mechanism 6 is fixedly installed on the inner wall of the box body 1 near the upper side, a filter screen plate 7 is placed on the upper surface of the placing mechanism 6, and a cleaning mechanism 8 is provided on the filter screen plate 7. A conical bucket 9 is fixedly installed on the lower surface of the filter screen plate 7, and a grid sleeve 10 is fixedly installed on the middle part of the lower side wall of the box body 1, and a filter screen cover 11 is threadedly installed on the upper surface of the grid sleeve 10.

[0020] Specifically, the support mechanism 4 includes a spring 401, a transverse plate 402, a guide rod 403 and a support plate 404. The spring 401 is fixedly installed on the lower surface of the drain cover 2, and the transverse plate 402 is fixedly installed between the front and rear springs 401. The guide rod 403 is fixedly installed on the lower surface of the drain cover 2 corresponding to the transverse plate 402, and the guide rod 403 is movably inserted on the transverse plate 402. The support plate 404 is fixedly installed on the upper surface of the transverse plate 402, and the upper surface of the support plate 404 is fixedly connected to the lower surface of the cylinder 5.

[0021] In this embodiment, the spring 401 pulls the horizontal plate 402 upward, so that the horizontal plate 402 drives the cylinder 5 upward through the support plate 404. The upper surface of the cylinder 5 is higher than the upper surface of the drainage cover 2, preventing larger impurities such as leaves from covering and clogging the rectangular drainage hole 3, ensuring that water on the road surface can flow in through the rectangular drainage hole 3.

[0022] Specifically, the diameter of the cylinder 5 is 1 cm-1.5 cm smaller than the width of the rectangular drain hole 3 , and the upper surface of the cylinder 5 is 1 cm-1.2 cm higher than the upper surface of the drain cover 2 .

[0023] In this embodiment, the cylinder 5 does not affect the inflow of water, and the cylinder 5 can ensure that impurities are lifted up.

[0024] Specifically, the placement mechanism 6 includes a fixed plate 601, an insertion rod 602 and a slot 603. The fixed plate 601 is fixedly installed on the inner walls of the box body 1. The insertion rod 602 is evenly fixed on the upper surface of the fixed plate 601. The filter plate 7 corresponding to the insertion rod 602 is provided with a slot 603, and the insertion rod 602 is inserted into the slot 603.

[0025] In this embodiment, the fixing plate 601 is used to fix the rod 602, and the filter screen plate 7 is installed on the rod 602 on the upper surface of the fixing plate 601 through the slot 603, so that the filter screen plate 7 is installed stably.

[0026] Specifically, the cleaning mechanism 8 includes a rotating shaft 801, a bearing assembly 802, a turbine blade 803, a first scraper 804 and a second scraper 805. The rotating shaft 801 is installed in the middle of the filter screen plate 7 through the bearing assembly 802. The turbine blade 803 is provided on the rotating shaft 801 in the conical bucket 9. The upper surface of the rotating shaft 801 is located on the upper surface of the filter screen plate 7 and is provided with a first scraper 804. The lower surface of the rotating shaft 801 is located on the upper surface of the filter screen cover 11 and is fixedly installed with a second scraper 805.

[0027] In this embodiment, the conical bucket 9 allows water to flow to the turbine blades 803, and the water flow drives the turbine blades 803 to rotate. The turbine blades 803 drive the rotating shaft 801 to rotate in the bearing assembly 802, so that the rotating shaft 801 drives the first scraper 804 and the second scraper 805 to rotate. The first scraper 804 cleans the impurities on the upper surface of the filter plate 7 to avoid impurity accumulation. The second scraper 805 cleans the impurities on the upper surface of the filter screen 11 to avoid blockage of the filter screen 7 and the filter screen cover 11, thereby ensuring smooth water flow.

[0028] Specifically, rectangular grooves 12 are provided on the upper surface of the drain cover 2 near the left and right positions.

[0029] In this embodiment, the rectangular groove 12 facilitates the use of a crowbar or the like to tilt and open the drain cover 2 .

[0030] When in use, the box body 1 is a drainage well, which is embedded in the road surface. The upper surface of the box body 1 is lower than or flush with the road surface. The grid sleeve 10 is connected to the urban drainage network. The cross plate 402 is pulled upward by the spring 401 in the support mechanism 4, so that the cross plate 402 drives the cylinder 5 upward through the support plate 404. The upper surface of the cylinder 5 is higher than the upper surface of the drainage cover 2, preventing larger impurities such as leaves from covering and clogging the rectangular drainage hole 3, ensuring that water on the road surface can flow in through the rectangular drainage hole 3. At the same time, the support mechanism 4 enables the cylinder 5 to shrink downward so that the upper surface of the cylinder 5 is flush with the drainage cover 2, and will not affect the driving of cars, etc. Rainwater flows into the box body 1 through the rectangular drainage hole 3 and flows to the filter screen. Plate 7, the filter screen plate 7 filters impurities in the water, and the water filtered by the filter screen plate 7 flows into the conical bucket 9, and then flows to the turbine blades 803 in the cleaning mechanism 8 through the conical bucket 9, so that the water flow drives the turbine blades 803 to rotate, and the turbine blades 803 drive the rotating shaft 801 to rotate in the bearing assembly 802, so that the rotating shaft 801 drives the first scraper 804 and the second scraper 805 to rotate, and the first scraper 804 cleans the impurities on the upper surface of the filter screen plate 7 to avoid impurity accumulation, and the second scraper 805 cleans the impurities on the upper surface of the filter screen cover 11, so that the water flow passes through the filter screen cover 11 and the mesh sleeve 10 and flows into the drainage pipe, ensuring smooth drainage and effectively avoiding road surface water.

[0031] To sum up, in this flood-proof road drainage structure, the cylinder 5 lifts up larger garbage, and the rectangular drainage hole 3 will not be covered or blocked, so that water can flow in. At the same time, the filter plate 7 and the filter cover 11 perform secondary filtration to prevent impurities from flowing in and causing blockage in the drainage pipe. The filter plate 7 and the filter cover 11 can be cleaned to ensure smooth drainage and effectively avoid road waterlogging.

[0032] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
