Description

Technical Field

[0001] The utility model belongs to the technical field of road drainage, and in particular relates to a road drainage device. Background Art

[0002] The roadbed is the foundation of the highway pavement, effectively preventing road collapse, subsidence, and other traffic-impeding accidents. However, when the roadbed drainage system is ineffective, water can accumulate on the road surface. This waterlogging not only affects vehicle traffic but also reduces the strength of the roadbed, potentially causing road subsidence and collapse.

[0003] Some existing roadbed drainage systems feature drainage channels on both sides of the road, connecting them to a water collection tank. This allows accumulated water on the road surface to flow into the channels on both sides and then drain into the water collection tank, reducing water accumulation on the road surface. However, most existing roadbed drainage systems connect the drainage channels to the water collection tank through a single pipe, which can easily lead to excessive water accumulation in the channels. In even larger cases, the water can easily overflow from the water storage tank onto the road surface, still impacting the road surface.

[0004] Therefore, there is an urgent need for a road drainage device to solve the above problems. Utility Model Content

Those skilled in the art will understand the specific meanings of the above terms in this utility model based on specific circumstances.

[0032] The technical solution of the present invention will be further described below with reference to the accompanying drawings and through specific implementation methods.

[0033] like Figures 1 to 5 As shown, this embodiment provides a road drainage device, which improves the drainage rate of the drainage ditch 2, effectively avoids the accumulation of water in the drainage ditch 2, and ensures the drainage effect of the roadbed 200.

[0034] See Figure 1 and Figure 2 The road includes a road surface 100 and a roadbed 200 provided below the road surface 100. The road drainage device includes a water collecting tank 1 buried in the roadbed 200 and two drainage grooves 2. The two drainage grooves 2 are provided on the road surface 100 along its width direction ( Figure 1 On both sides of the road surface 100 (in the X direction), water on the road surface 100 can flow into the drainage ditch 2; the road drainage device also includes a connecting pipe 3, a plurality of first drainage pipes 4 and a plurality of second drainage pipes 5. The connecting pipe 3 is buried in the roadbed 200 and is connected to the water collecting tank 1, and the end of the connecting pipe 3 connected to the water collecting tank 1 is lower than the end of the connecting pipe 3 away from the water collecting tank 1; the plurality of first drainage pipes 4 are arranged along the length direction of the road surface 100 (in the X direction). Figure 2A plurality of first drain pipes 4 are arranged at intervals along the length of the road surface 100 (in the Y direction), one end of the first drain pipe 4 is connected to the drain trough 2 on the first side of the road surface 100, and the other end is connected to the connecting pipe 3. Water in the drain trough 2 on the first side of the road surface 100 can flow sequentially through the first drain pipe 4 and the connecting pipe 3 to the water collection tank 1. A plurality of second drain pipes 5 are arranged at intervals along the length of the road surface 100, one end of the second drain pipe 5 is connected to the drain trough 2 on the second side of the road surface 100, and the other end is connected to the connecting pipe 3. Water in the drain trough 2 on the second side of the road surface 100 can flow sequentially through the second drain pipe 5 and the connecting pipe 3 to the water collection tank 1. Alternatively, the plurality of second drain pipes 5 correspond one-to-one with the plurality of first drain pipes 4, one end of the second drain pipe 5 is connected to the drain trough 2 on the second side of the road surface 100, and the other end is connected to the corresponding first drain pipe 4. Water in the drain trough 2 on the second side of the road surface 100 can flow sequentially through the second drain pipe 5, the first drain pipe 4, and the connecting pipe 3 to the water collection tank 1. The first side and the second side are the two sides of the road surface 100 along its width direction, respectively.

[0035] In the road drainage device provided by this embodiment, when the amount of water in the drainage trough 2 increases, the first drain pipe 4 and the second drain pipe 5 can drain the water in the corresponding area of ​​the drainage trough 2 to the connecting pipe 3, and then through the connecting pipe 3 to the water collection tank 1. The multiple rows of first drain pipes 4 and the multiple rows of second drain pipes 5 increase the drainage rate of the drainage trough 2, allowing the water in the drainage trough 2 to be drained quickly, effectively preventing water accumulation in the drainage trough 2 and ensuring effective drainage of the roadbed 200. The first drain pipes 4 and the second drain pipes 5 can both transport water to the connecting pipe 3, allowing the connecting pipe 3 to collect water on the road surface 100 for subsequent recycling. The end of the connecting pipe 3 connected to the water collection tank 1 is lower than the end of the connecting pipe 3 away from the water collection tank 1. That is, the connecting pipe 3 is vertically inclined within the roadbed 200, allowing water to automatically flow from the end of the connecting pipe 3 away from the water collection tank 1 toward the water collection tank 1. This facilitates the rapid discharge of water in the connecting pipe 3, prevents water accumulation in the connecting pipe 3, and ensures effective drainage.

[0036] Specifically, see Figure 1 and Figure 2 The water collecting tank 1 and the connecting pipe 3 are both located on the first side of the road surface 100, and the water collecting tank 1 is arranged at the end of the drainage trough 2 along its length direction. The first drainage pipe 4 extends vertically and is located above the connecting pipe 3. The second drainage pipe 5 includes a connected vertical section and an inclined section. The vertical section is connected to the drainage trough 2 on the second side, and the inclined section is connected to the connecting pipe 3. The height of the inclined section away from one end of the connecting pipe 3 is higher than the height of the end connected to the connecting pipe 3, so that water can automatically flow from the second side of the road surface 100 to the connecting pipe 3 on the first side under the action of gravity.

[0037] Furthermore, to ensure the drainage rate of the connecting pipe 3, the diameter of the connecting pipe 3 is larger than the diameters of the first drainage pipe 4 and the second drainage pipe 5. In this embodiment, the diameter of the connecting pipe 3 is 3 to 5 times the diameter of the first drainage pipe 4.

[0038] In other embodiments, multiple second drain pipes 5 correspond one-to-one to multiple first drain pipes 4, and the second drain pipes 5 are connected to the corresponding first drain pipes 4. To ensure the drainage rate of the connecting pipe 3 and the first drain pipe 4, the diameter of the connecting pipe 3 is greater than the diameter of the first drain pipe 4, and the diameter of the first drain pipe 4 is greater than the diameter of the second drain pipe 5.

[0039] Optionally, see Figure 1 and Figure 2 Each drainage trough 2 is provided with a plurality of connected manhole covers 6. The manhole covers 6 are detachably connected to the roadbed 200, and any two adjacent manhole covers 6 are snap-fitted together. The multiple manhole covers 6 can block the slot openings. The manhole covers 6 are provided with through holes 61, through which water on the road surface 100 can enter the drainage trough 2. The manhole covers 6 block the slot openings, allowing water on the road surface 100 to enter the drainage trough 2 only through the small through holes 61 on the manhole covers 6. This prevents debris such as garbage and fallen leaves from entering the drainage trough 2 with the water flow, thereby preventing the road drainage system from clogging. This allows the road drainage system to function normally. The manhole covers 6 can be detached from the roadbed 200 and snap-fitted with adjacent manhole covers 6. When a blockage occurs in the drainage trough 2, workers can inspect the situation inside the trough 2 by individually removing the manhole covers 6 at any position, quickly locating the blockage and improving the efficiency of road drainage system maintenance.

[0040] In this embodiment, refer to Figure 3 A slot 62 is provided at one end of the manhole cover 6, and a block 63 is provided at the other end. The block 63 of any manhole cover 6 can be inserted into the slot 62 of the adjacent manhole cover 6 to achieve the connection between the two manhole covers 6. While ensuring the firmness of the connection between the two manhole covers 6, it is also convenient for the staff to separate the two adjacent manhole covers 6 later to inspect and repair the road drainage device.

[0041] For example, see Figure 1 and Figure 3 The cross-sectional shapes of the block 63 and the slot 62 are the same, and both are T-shaped. After the block 63 is inserted into the slot 62, the head of the T-shaped slot 62 can contact the head of the T-shaped block 63, thereby preventing the block 63 from escaping from the slot 62 along the length direction of the road surface 100.

[0042] Optionally, see Figure 4The road drainage device also includes a flow detection component 7 arranged in the water collecting tank 1. The flow detection component 7 is used to detect the water flow in the water collecting tank 1 so that the staff can monitor the water flow in the water collecting tank 1 at any time to prevent the water from being unable to be discharged normally into the water collecting tank 1 when the water flow in the water collecting tank 1 is too large.

[0043] In this embodiment, refer to Figure 4 The flow detection assembly 7 includes a float 71 and two sensors 72. The float 71 floats on the water surface within the water collection tank 1 and moves vertically with the water surface. The two sensors 72 are vertically spaced apart on the inner wall of the water collection tank 1 and are used to sense the position of the float 71. When the water level within the water collection tank 1 changes, the float 71 moves up and down with the water level. When the water level rises to the position of the sensors 72, the sensors 72 will sense the float 71. The flow rate within the water collection tank 1 is determined by calculating the time difference between the float 71 passing the two sensors 72, thereby ensuring the normal operation of the water collection tank 1.

[0044] Specifically, see Figure 4 One of the two sensors 72 is set at the top of the water collecting tank 1, and the other is set at the middle of the water collecting tank 1. The two sensors 72 can sense the floating plate 71 in turn, thereby determining the flow rate in the water collecting tank 1.

[0045] Exemplarily, the sensor 72 is an infrared touch sensor.

[0046] Further, see Figure 4 A vertically extending connecting rod 73 is provided in the water collecting tank 1, and the floating plate 71 is slidably sleeved on the connecting rod 73. The connecting rod 73 can limit the horizontal movement of the floating plate 71, so that the floating plate 71 can only move vertically along the extending direction of the connecting rod 73, so as to ensure the accuracy of the obtained time difference.

[0047] Specifically, the floating plate 71 is provided with a perforation, the walls of which are mounted with rolling balls. The connecting rod 73 passes through the perforation and rolls with the balls. As the floating plate 71 moves vertically with the water level, the balls roll, causing the floating plate 71 to slide relative to the connecting rod 73. The balls reduce friction between the floating plate 71 and the connecting rod 73, allowing the floating plate 71 to move smoothly on the connecting rod 73 and preventing friction from affecting the accurate value of the time difference.

[0048] Furthermore, the two sensors 72 are located on the same vertical line, and the connecting rod 73 is provided in the water collecting tank 1 close to the sensor 72 so that the sensor 72 can quickly sense the floating plate 71 .

[0049] Optionally, see Figure 1 and Figure 5A detachable filter element 8 is provided in the drainage trough 2, and the filter element 8 is used to filter the water entering the drainage trough 2, further preventing garbage, fallen leaves and other debris from entering the first drainage pipe 4 and the second drainage pipe 5, and avoiding clogging the first drainage pipe 4, the second drainage pipe 5 and the connecting pipe 3.

[0050] Furthermore, a plurality of filter elements 8 are provided, and the plurality of filter elements 8 correspond one-to-one to the plurality of manhole covers 6 to ensure the filtering effect along the length direction of the drainage trough 2 .

[0051] In this embodiment, refer to Figure 5 A mounting seat 21 is provided on the wall of the drain trough 2. The road drainage device further includes a fastener 9, which passes through the filter element 8 and is threadedly connected to the mounting seat 21 to secure the filter element 8 in the drain trough 2. The threaded connection between the fastener 9 and the mounting seat 21 not only facilitates the installation of the filter element 8, but also facilitates the removal of the filter element 8 from the mounting seat 21, thereby facilitating subsequent replacement of the filter element 8.

[0052] For example, see Figure 5 The filter element 8 includes a frame and a filter mesh. The frame is arranged along the circumference of the filter mesh and is fixedly connected to the filter mesh. There are multiple mounting seats 21 and fasteners 9. Multiple mounting seats 21 are arranged at intervals along the circumference of the drain groove 2. Multiple fasteners 9 correspond one-to-one to multiple mounting seats 21. The fasteners 9 are bolts. The bolts pass through the frame and are threadedly connected to the corresponding mounting seats 21 to firmly mount the filter element 8 on the drain groove 2 along the circumference of the filter element 8.

[0053] Optionally, see Figure 1 and Figure 4 The road drainage device also includes a pumping pipe 10, a pumping member 11, and a third drainage pipe 12. The pumping member 11 is arranged in the water collecting tank 1 and is connected to the interior of the water collecting tank 1 through the pumping pipe 10. One end of the third drainage pipe 12 is connected to the pumping member 11, and the other end extends to the outside of the roadbed 200. The pumping member 11 is used to pump water from the water collecting tank 1 to the outside of the roadbed 200. When the amount of water in the water collecting tank 1 exceeds the set amount, the water in the water collecting tank 1 can be pumped to the outside of the roadbed 200 by opening the pumping member 11 to ensure the normal use of the road drainage device. When the amount of water in the water collecting tank 1 exceeds the set amount, the staff can either pump out the water in the water collecting tank 1 by opening the manhole cover 6 at the corresponding position or by opening the pumping member 11, thereby expanding the applicability of the road drainage device provided by this embodiment.

[0054] Exemplarily, the water pumping member 11 is a water pump.

[0055] In this embodiment, refer to Figure 1 and Figure 4An installation box 13 is provided at the bottom of the water collecting tank 1, and the pumping component 11 is provided in the installation box 13 to protect the pumping component 11 and prevent the pumping component 11 from being damaged by the surrounding roadbed 200, groundwater, etc.; the pumping pipe 10 is L-shaped, one end is connected to the pumping component 11, and the other end extends into the water collecting tank 1 and extends toward the bottom of the water collecting tank 1, so that all the water in the water collecting tank 1 can be pumped out.

[0056] Furthermore, a certain distance is maintained between the end of the L-shaped water pumping pipe 10 extending into the water collecting tank 1 and the bottom surface of the water collecting tank 1 to prevent the pumping member 11 from pumping in the sediment deposited at the bottom of the water collecting tank 1 .

[0057] Optionally, the road drainage device also includes a controller, which is electrically connected to the two sensors 72 and the pumping component 11. The controller can obtain the time when the two sensors 72 sense the floating plate 71, and calculate the time difference between the floating plate 71 passing through the two sensors 72 based on the obtained time, thereby calculating the current water flow in the water collecting tank 1. When the obtained water flow exceeds the set water volume value, the controller controls the pumping component 11 to start working to drain the water in the water collecting tank 1.

[0058] Exemplarily, the controller is set according to a specific usage environment, and the controller may be, but is not limited to, a single-chip microcomputer, a high-end reduced instruction set machine, or a field programmable gate array.

[0059] The above description is only a specific implementation method of the present invention, but the protection scope of the present invention is not limited thereto. Those skilled in the art should understand that any changes or substitutions that can be easily thought of by those skilled in the art within the technical scope disclosed in the present invention fall within the protection scope and disclosure scope of the present invention.
