Description

Technical Field

[0001] This application belongs to the technical field of road drainage systems, specifically relating to an automatic opening road drainage assembly for heavy rainfall. Background Technology

[0002] Drainage systems are installed on both sides of the road to collect rainwater. These systems mainly consist of rainwater wells, drainage pipes, and drainage grates covering the wells. The main function of the drainage grates is to cover the well inlets to prevent people from falling in, and also to block large debris such as tree branches from flowing into the wells with rainwater.

[0003] However, during heavy rainfall, the large amount of precipitation per unit time, coupled with the unchanged size of the filter holes on the drainage grates, leads to delayed drainage and severe water accumulation on the roads. Currently, when encountering heavy rainfall, sanitation workers mostly open the drainage grates in advance based on weather forecasts, exposing the inlets of the storm drains to increase the drainage speed.

[0004] However, when the weather forecast is inaccurate, especially when there is heavy rain at night, sanitation workers do not have time to open the drainage grates on both sides of the road, resulting in severe water accumulation and even flooding. Utility Model Content

[0005] The technical problem to be solved by this application is to overcome the shortcomings of the prior art and provide an automatic opening road drainage assembly for heavy rainfall. When the rainfall in a unit of time rises to a threshold, the drainage grate will automatically flip open to increase the water intake of the rainwater well and avoid road water accumulation and flooding.

[0006] The technical solution adopted by this application to solve its existing problems is: An automatic opening road drainage assembly for heavy rainfall includes a drainage grate, a support frame, a water collection tank, and a tilting control device.

[0007] The drainage grate is fitted inside the supporting frame, and the end of the drainage grate is rotatably connected to the supporting frame.

[0008] The water collection tank, with its upper open end, is slidably mounted below the supporting frame, and the water collection tank is equipped with a drain hole.

[0009] The water collection tank and the drainage grate are linked by a flipping control device.

[0010] Preferably, the bottom of the water collection tank is connected to several vertically arranged retractable spring support devices.

[0011] Preferably, a vertical rod is fixed below the supporting frame, the vertical rod is inserted into the interior of the water collection tank, and the outer wall of the vertical rod abuts against the water collection tank.

[0012] The flipping control device includes a control rod and a top rod that are fixedly connected to each other. The angle between the control rod and the top rod is 70° to 90°. The connection between the control rod and the top rod is rotatably connected to the bottom of the vertical rod via a pivot. A counterweight is connected to the outer side of the end of the control rod away from the top rod.

[0013] Preferably, the top of the control rod is connected to a mounting plate on the side opposite to the top rod, and a counterweight is fixed to the end of the mounting plate. The counterweight is located on the outside of the water collection tank.

[0014] Preferably, the drainage grate is provided with at least two parallel control rods on one side, and the control rods are fixedly connected to each other by a connecting plate.

[0015] Preferably, the inner wall of the water collection tank is provided with a limiting plate.

[0016] When the water collection tank slides to the upper stop point, the bottom of the vertical rod and the control rod both abut against the top surface of the limit plate.

[0017] Preferably, the bottom of the load-bearing frame is provided with 1-3 spaced support plates, and the horizontally arranged drainage grates are placed on the support plates.

[0018] Preferably, the end of the drainage grate furthest from the rotatable connection with the supporting frame is provided with a hook hole.

[0019] Compared with the prior art, the beneficial effects of this application are as follows: (1) The water collection tank moves up and down by the amount of rainfall per unit time. When the amount of rainfall is greater than the threshold, the water collection tank will drop to the set height and then lift the drainage grate through the flip control device to open the inlet of the rainwater well, increase the amount of water entering, optimize the road drainage effect, and avoid water accumulation on the road and waterlogging.

[0020] (2) The supporting frame is provided with several spaced support plates under the drainage grate. The gaps between the support plates do not affect the drainage volume, but can prevent people from falling into the rainwater well and improve the safety of the drainage grate after it is opened.

Detailed Implementation

[0024] The attached figure shows a preferred embodiment of the automatic opening road drainage assembly for heavy rainfall. The following is a more detailed description of this application in conjunction with the attached figure.

[0025] Depend on Figures 1 to 10 As shown, an automatic opening road drainage assembly for heavy rainfall includes a drainage grate 1, a supporting frame 2, a water collection tank 3, and a tilting control device 5.

[0026] During installation, the water collection tank 3 and the flip control device 5 are installed inside the rainwater well 6. An installation groove 601 is recessed on the top surface of the inlet of the rainwater well 6, and the edge of the supporting frame 2 is placed in the installation groove 601.

[0027] The drainage grate 1 is fitted inside the support frame 2, and the end of the drainage grate 1 is rotatably connected to the support frame 2.

[0028] The water collection tank 3, which is open at the top, is slidably mounted below the supporting frame 2. The water collection tank 3 is provided with a drain hole 301, and the position of the drain hole 301 corresponds to the position of the drain pipe 7 connected to the rainwater well 6.

[0029] The water collection tank 3 and the drainage grate 1 are linked by a flipping control device 5.

[0030] The bottom of the water collection tank 3 is connected to several vertically arranged retractable spring support devices 4. The retractable spring support devices 4 utilize existing technology, such as spring telescopic rods. They include a spring cylinder, inside which is a spring and a piston. The piston is located above the spring, and a telescopic rod is fixed above the piston. The top end of the telescopic rod extends to the outside of the spring cylinder and has a flange, which is bolted to the bottom of the water collection tank 3. The bottom of the spring cylinder has a mounting flange, which is bolted to the bottom of the rainwater well 6. The main components of the retractable spring support devices 4 are made of 304 or 316 stainless steel.

[0031] A vertical rod 202 is fixed below the supporting frame 2. The vertical rod 202 is inserted into the interior of the water collection tank 3, and the outer wall of the vertical rod 202 abuts against the inner wall of the water collection tank 3.

[0032] The flipping control device 5 includes a control rod 501 and a top rod 502 that are fixedly connected to each other. The included angle between the control rod 501 and the top rod 502 is 70° to 90°. In this embodiment, the control rod 501 and the top rod 502 are arranged perpendicular to each other.

[0033] The connection between the control rod 501 and the top rod 502 is rotatably connected to the bottom of the vertical rod 202 via a pivot. A counterweight 504 is connected to the outer side of the end of the control rod 501 away from the top rod 502.

[0034] The inner wall of the water collection tank 3 is provided with a limiting plate 302. When the water collection tank 3 slides to the upper stop point, the bottom of the vertical rod 202 and the control rod 501 abut against the top surface of the limiting plate 302.

[0035] Under the pushing action of the retractable spring support device 4, the water collection tank 3 moves upward until the limiting plate 302 abuts against the vertical rod 202. At this time, the control rod 501 is in a vertical state, and the vertical surface on the side away from the top rod 502 abuts against the inner wall of the water collection tank 3.

[0036] When it rains, rainwater flows into the collection tank 3 through the drainage grate 1 and is discharged into the rainwater well 6 through the drainage hole 301, and finally discharged through the drainage pipe 7. When the rainfall per unit time increases, since the size of the drainage hole 301 remains unchanged, as the amount of rainwater increases, the liquid level inside the collection tank 3 and the overall weight gradually increase, which in turn pushes the telescopic rod of the telescopic spring support device 4 downward.

[0037] Depend on Figure 3 As shown, when the water collection tank 3 moves down to below the control rod 501, the limiting effect on the control rod 501 is released. Under the action of the counterweight 504, the control rod 501 flips outward, which in turn drives the end of the top rod 502 to rotate upward. After the top rod 502 contacts the bottom surface of the drainage grate 1, it lifts the drainage grate 1, increases the rainwater inflow of the rainwater well 6, and prevents road water accumulation.

[0038] After the rainwater decreases, the water stored inside the water collection tank 3 is discharged through the drain hole 301, the liquid level drops, and then moves upward, pushing the control rod 501 back to the vertical state, the top rod 502 moves downward, and the drain grate 1 is reset.

[0039] To optimize the function of the counterweight 504, a mounting plate 503 is connected to the side of the control rod 501 opposite to the top rod 502. The counterweight 504 is fixed to the end of the mounting plate 503 and is located on the outside of the water collection tank 3. Preferably, when the control rod 501 is arranged vertically, the mounting plate 503 is arranged at an angle downwards.

[0040] In order for the top rod 502 to better support and open the drainage grate 1, the drainage grate 1 is provided with at least two parallel control rods 501 at intervals on one side, and the control rods 501 are fixedly connected to each other by a connecting plate 505.

[0041] The supporting frame 2 has 1-3 spaced support plates 201 at its bottom, and the horizontally arranged drainage grates 1 are placed on the support plates 201. The support plates 201 support the drainage grates 1 and also prevent people from accidentally falling into the rainwater well 6 when the drainage grates 1 are opened.

[0042] The drainage grate 1 is provided with a hook hole 101 at the end away from the rotatable connection with the supporting frame 2, so as to facilitate manual opening of the drainage grate 1 for maintenance and cleaning.

[0043] Reflective paper is affixed to the surface of the drainage grate 1, which can provide a warning to pedestrians or vehicles when rotated to an inclined state. A single drainage grate 1 can be rotatably mounted inside the supporting frame 2, or two opposing drainage grates 1 can be rotatably connected.

[0044] The embodiments of this application have been described in detail above with reference to the accompanying drawings. However, this application is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this application.
