Description

Technical Field

[0001] This application relates to the technical field of drainage equipment, and in particular to a drainage device for preventing urban flooding. Background Technology

[0002] Currently, there are frequent heavy rainstorms in summer, with high rainfall intensity, often resulting in a large amount of precipitation in a short period of time. Due to the poor drainage systems in many cities, large amounts of precipitation can easily cause water to accumulate on roads, leading to urban flooding. This often results in traffic paralysis in many cities when heavy rainfall occurs.

[0003] In related technologies, drainage systems include grates, transition channels, pipes, and water storage tanks. Multiple grates and pipes are installed. The transition channels are vertically installed, with grates attached to their tops. The grates are arranged along the road's direction of extension. The bottom of the transition channels is connected to the water storage tank via pipes. During rain, water enters the transition channels from the grates, and water from the multiple transition channels flows into the water storage tank through the pipes.

[0004] Regarding the aforementioned technologies, the inventors believe that during heavy rainfall, the large amount of precipitation causes water accumulation on the road surface. The rainwater carries debris from the road surface towards the grates. When the rainwater enters the transition channel, some debris remains on the grates, causing them to become clogged. This prevents rainwater from flowing properly into the transition channel, potentially leading to flooding. Summary of the Invention

[0005] In order to reduce the occurrence of urban flooding, the present invention provides an urban drainage device for preventing urban flooding.

[0006] The present invention provides a city drainage device for preventing urban flooding, which adopts the following technical solution:

[0007] A flood-prevention urban drainage device includes a water pipe running through a road shoulder and connected to the outside at one end, a transition channel connected to the water pipe, and a water storage tank located below the transition channel. The water storage tank and the transition channel are connected via a first connecting pipe. A filter assembly is connected inside the water pipe. The filter assembly includes a mounting plate abutting against the opening of the water pipe near the outside, a fixed rod connected to the mounting plate, and multiple branch rods connected to the fixed rod. Multiple water holes connected to the water pipe are horizontally opened on the side wall of the mounting plate. The ends of the multiple branch rods away from the fixed rod abut against the inner wall of the water pipe, and the ends away from the fixed rod are all inclined towards the outside.

[0008] By adopting the above technical solution, during heavy rainfall, rainwater from the road surface flows into the water pipe through the drainage holes. The mounting plate blocks some larger debris from entering the water pipe, and the inclined bifurcated rod further retains the debris, preventing it from clogging the water pipe and further reducing the possibility of larger debris entering the transition channel. This reduces the occurrence of road flooding due to water pipe blockage, thereby reducing urban flooding. The rainwater then enters the transition channel, and the rainwater in the transition channel flows into the storage tank through the first connecting pipe. When there is a lot of debris blocked on the filter component, it will hinder the flow rate of rainwater. The mounting plate can be directly removed along with the fixing rod, and then the debris remaining on the bifurcated rod can be cleaned. It is simple and easy to operate.

[0009] Preferably, a first filter element is fixedly connected to the inner wall of the first connecting pipe, a cleaning device for cleaning the first filter element is provided in the transition groove, and a moving component that drives the cleaning device is connected to the fixed rod.

[0010] By adopting the above technical solution, the first filter element further filters the rainwater in the transition channel, further preventing debris from entering the water storage tank. Removing the mounting plate will move the fixing rod, which in turn moves the moving component. The moving component then drives the cleaning device to clean the first filter element, preventing blockage or partial blockage that could affect the flow of rainwater from the transition channel to the water storage tank, thus reducing road flooding and consequently reducing urban waterlogging.

[0011] Preferably, the cleaning device includes a connecting rod, a first cleaning component connected to the connecting rod, and a limiting component that restricts the position of the connecting rod, wherein the first cleaning component abuts against the first filter component.

[0012] By adopting the above technical solution, when the first filter element is clogged, or when cleaning debris on the forked rod, the mounting plate is moved, the mounting plate drives the fixed rod to move, the fixed rod drives the moving component to move, the moving component drives the connecting rod to move, and the connecting rod drives the first cleaning component to clean the first filter element. The operation is simple and prevents water accumulation on the road due to clogging of the first filter element, thus reducing the occurrence of urban flooding.

[0013] Preferably, the limiting component includes a first limiting rod fixedly connected to the inner wall of the transition groove and a second limiting rod fixedly connected to the inner wall of the transition groove. Both the first limiting rod and the second limiting rod are connected to a fixing sleeve. The fixing sleeve is sleeved on the connecting rod and slidably connected to the connecting rod.

[0014] By adopting the above technical solution, the first limiting rod, the second limiting rod and the fixed sleeve cooperate to restrict the movement direction of the connecting rod, preventing the connecting rod from causing the first cleaning component to shift, thus preventing the first filter component from being cleaned, causing the first filter component to become clogged, which may lead to water accumulation on the road and thus cause urban flooding.

[0015] Preferably, the bottom end of the connecting rod is connected to a locking block, and when the end of the fixing rod away from the mounting plate is located at the end of the water pipe closer to the outside, the locking block abuts against the fixing sleeve.

[0016] By adopting the above technical solution, the locking block and the fixing sleeve cooperate to prevent the connecting rod from detaching from the fixing sleeve. At the same time, when the mounting plate is pulled, all the branch rods can be pulled out to the outside, and it can ensure that the debris on multiple branch rods can be cleaned.

[0017] Preferably, the first connecting pipe is located near the bottom of the transition groove, and the transition groove is connected to a second connecting pipe near the top. A second filter element is disposed inside the second connecting pipe, and the cleaning device further includes a second cleaning element for cleaning the second filter element. The second cleaning element is fixedly connected to the connecting rod.

[0018] By adopting the above technical solution, rainwater enters the transition channel and is first discharged into the storage tank through the first connecting pipe. When the first filter element becomes clogged, or when the rainfall is heavy, a large amount of water accumulates in the transition channel. When the water level exceeds the second connecting pipe, the accumulated water enters the storage tank through the second connecting pipe. The second filter element further filters impurities in the accumulated water. When workers move the installation plate, it moves the fixing rod, which in turn moves the moving component. The moving component then moves the second cleaning component to clean the second filter plate, preventing clogging of the second filter plate and thus preventing road flooding and urban waterlogging.

[0019] Preferably, the moving component includes a connecting rope for moving the connecting rod, and the connecting rope is connected to the fixed rod.

[0020] By adopting the above technical solution, when the first filter element or the second filter element is clogged, or when cleaning debris on the forked rod, the fixed rod moves, causing the connecting rope to move. The connecting rope then moves the connecting rod, which in turn moves the first cleaning element and the second cleaning element.

[0021] Preferably, the moving component further includes a support block and a roller fixedly connected to the inner wall of the transition groove. Two support blocks are arranged at an angle and in parallel. The roller is disposed inside the two support blocks and is rotatably connected to the support blocks. The connecting rope abuts against the roller.

[0022] By adopting the above technical solution, the support block and roller cooperate to restrict the position of the connecting rope, and the roller reduces the wear of the connecting rope, increases the service life of the connecting rope, and makes it easier for the fixed rod to drive the connecting rod to move.

[0023] Preferably, the bottom surface of the water pipe opening near the outside is lower than the road surface.

[0024] By adopting the above technical solution, water on the road surface can quickly flow into the drainage pipe, reducing the possibility of water accumulation on the road.

[0025] In summary, the present invention has the following beneficial effects:

[0026] 1. Rainwater flows into the transition channel through the water pipe, and the water in the transition channel flows into the storage tank through the first connecting pipe. The debris carried by the rainwater stays on the branch bar and does not affect the rainwater entering the transition channel, thereby reducing road water accumulation and reducing the occurrence of urban flooding.

[0027] 2. Water in the transition channel enters the storage tank through the first filter element and the second filter element. When cleaning debris on the forked rod, the fixed rod drives the connecting rope to move, the connecting rope drives the connecting rod to move, and the connecting rod drives the first cleaning element and the second cleaning brush to move. The first cleaning element cleans the first filter element, and the second cleaning element cleans the second filter element, preventing the first connecting pipe and the second connecting pipe from becoming blocked, reducing road surface water accumulation, and reducing the occurrence of urban flooding.

Detailed Implementation

[0033] The present invention will be further described in detail below with reference to the accompanying drawings.

[0034] A city drainage device for preventing urban flooding, referring to Figure 1 It includes a water pipe 1 that passes through the road shoulder and connects to the outside, a transition trough 2 connected to the end of the water pipe 1 away from the outside, a first connecting pipe 3, a water storage tank 5, a filter assembly 6, and a first filter element. The transition trough 2 is connected to the water storage tank 5 through the first connecting pipe 3, so that the water in the transition trough 2 is passed into the water storage tank 5 for storage. The filter assembly 6 is located inside the water pipe 1 and is used to filter larger debris without clogging the water pipe 1. The first filter element is connected to the inner wall of the first connecting pipe 3 and is used to filter smaller debris in the rainwater in the transition trough 2.

[0035] Reference Figure 1 Water pipe 1 is a rectangular tube with its end away from the outside inclined downwards. Its bottom opening near the outside is lower than the road surface, and its bottom end is connected to the transition trough 2. The first connecting pipe 3 is located on the side wall of the transition trough 2 and is close to the bottom of the transition trough 2. The transition trough 2 is connected to the second connecting pipe 4. One end of the second connecting pipe 4 is located on the side wall of the transition trough 2 opposite to the first connecting pipe 3 and is close to the top of the transition trough 2. The other end is connected to the water storage tank 5.

[0036] The downward-sloping water pipe 1 facilitates the inflow of water from the road surface, and the bottom surface of the opening of the water pipe 1 near the outside is lower than the road surface, allowing water on the road surface to flow quickly into the water pipe 1, reducing the possibility of water accumulation on the road surface. Both the first connecting pipe 3 and the second connecting pipe 4 can drain the water in the transition trough 2 into the water storage tank 5. After the water enters the transition trough 2, it first flows into the water storage tank 5 through the first connecting pipe 3. When the first filter is blocked, or when the rainfall is heavy, there is a lot of water in the transition trough 2, and the water level exceeds the second connecting pipe 4. The water then flows into the water storage tank 5 through the second connecting pipe 4.

[0037] Reference Figure 1 To achieve the same purpose, the first filter element can be a first filter plate 31, a first filter cloth, etc. In this embodiment, a first filter plate 31 is selected. The first filter plate 31 is vertically arranged, its end face is fixedly connected to the inner wall of the first connecting pipe 3, and its side wall is flush with the inner wall of the transition groove 2. When water enters the water storage tank 5, the first filter plate 31 further filters impurities in the water.

[0038] Reference Figure 1 A second filter element is installed inside the second connecting pipe 4. To achieve the same purpose, the second filter element can be a second filter plate 41, a second filter cloth, etc. In this embodiment, a second filter plate 41 is selected. The second filter plate 41 is vertically arranged, its end face is fixedly connected to the inner wall of the second connecting pipe 4, and its side wall is flush with the inner wall of the transition groove 2. When water enters the water storage tank 5, the second filter plate 41 further filters the impurities in the water.

[0039] Reference Figure 1 and Figure 2 The filter assembly 6 includes a mounting plate 61, a fixing rod 62, and a forked rod 63. The mounting plate 61 is a plate-shaped body with a rectangular longitudinal section. The side wall of the mounting plate 61 abuts against the water pipe 1. Its bottom is higher than the road surface, and its top is higher than the top of the water pipe 1. Bolts pass through the mounting plate 61 and are threadedly connected to the road shoulder. Multiple water holes are horizontally opened on the side wall of the mounting plate 61, and all of them are connected to the water pipe.

[0040] Reference Figure 1 The fixed rod 62 is fixedly connected to the mounting plate 61 and is inclined, with its axis coinciding with the axis of the water pipe 1. Multiple branch rods 63 are inclined and evenly distributed around the circumferential wall of the fixed rod 62. One end of the branch rod 63 is fixedly connected to the circumferential wall of the fixed rod 62, and the other end abuts against the inner wall of the water pipe 1. The end of the branch rod 63 away from the fixed rod 62 is inclined towards the outside.

[0041] The bottom of the mounting plate 61 is higher than the road surface, allowing water on the road surface to flow quickly into the water pipe 1. The mounting plate 61 does not obstruct the flow, reducing the possibility of water accumulation on the road surface. The mounting plate 61 blocks some larger debris from entering the water pipe 1, preventing larger debris from entering the transition groove 2 and clogging the first filter plate 31 and the second filter plate 41. The forked rod 63 further retains larger debris without clogging the water pipe 1, reducing the occurrence of water accumulation on the road surface and thus reducing the occurrence of urban flooding.

[0042] When cleaning debris from the forked rod 63, rotate the bolt to remove the mounting plate 61. The mounting plate 61 moves the fixing rod 62, which in turn moves the forked rod 63. After removing the forked rod 63, the debris can be cleaned. After cleaning, the mounting plate 61 is then reinstalled in its original position.

[0043] Reference Figure 1 The bottom end of the fixed rod 62 is connected to a movable component 7. The movable component 7 includes a support block 71, a roller 72 and a connecting rope 73. There are two support blocks 71 arranged at an angle and in parallel. Both support blocks 71 are fixedly connected to the inner wall of the top surface of the water pipe 1, and the ends of the support blocks 71 that are away from the water pipe 1 are both inclined downwards. The roller 72 is placed between the two support blocks 71 and is rotatably connected to the support blocks 71. Its axis is set horizontally. One end of the connecting rope 73 is fixedly connected to the fixed rod 62.

[0044] When cleaning debris from the forked rod 63, the movement of the fixed rod 62 causes the connecting rope 73 to move. The roller 72 reduces wear on the connecting rope 73 and also makes it easier for the fixed rod 62 to move the connecting rod 81.

[0045] Reference Figure 2 and Figure 3The connecting rope 73 is connected to the cleaning device 8. The cleaning device 8 includes a connecting rod 81, a first cleaning component, a second cleaning component, and a limiting component 84. The connecting rod 81 is rectangular and vertically arranged. Its top end is fixedly connected to the connecting rope 73. In order to achieve the same purpose, the first cleaning component can be a first cleaning brush 82, a cleaning sponge, etc. In this embodiment, the first cleaning brush 82 is selected.

[0046] Reference Figure 1 and Figure 3 To achieve the same purpose, the second cleaning component can be a first cleaning brush 82, a cleaning sponge, etc. In this embodiment, a second cleaning brush 83 is selected. Both the first cleaning brush 82 and the second cleaning brush 83 are fixedly connected to the connecting rod 81, and the bristles of the first cleaning brush 82 abut against the first filter plate 31, and the second cleaning brush 83 abuts against the bristles of the second filter plate 41.

[0047] When cleaning debris from the forked rod 63, the fixed rod 62 moves the connecting rope 73, which in turn moves the connecting rod 81. The connecting rod 81 then moves the first cleaning brush 82 to clean the first filter plate 31, and simultaneously moves the second cleaning brush 83 to clean the second filter plate 41.

[0048] Reference Figure 2 and Figure 3 The limiting component 84 includes a first limiting rod 841 and a second limiting rod 842. Both the first limiting rod 841 and the second limiting rod 842 are horizontally arranged. The first limiting rod 841 is located above the first cleaning brush 82, and one end of it is fixedly connected to the inner wall of the transition groove 2. The second limiting rod 842 is located below the second cleaning brush 83, and one end of it is fixedly connected to the inner wall of the transition groove 2.

[0049] Reference Figure 3 The first limiting rod 841 is connected to a fixing sleeve, which includes a first fixing sleeve 8411 and a second fixing sleeve 8421. The first limiting rod 841 is fixedly connected to the first fixing sleeve 8411. The first fixing sleeve 8411 is sleeved on the connecting rod 81 and slidably connected to the connecting rod 81. The first fixing sleeve 8411 has a first through hole on its side wall near the first cleaning brush 82. The second limiting rod 842 is fixedly connected to the second fixing sleeve 8421. The second fixing sleeve 8421 is sleeved on the connecting rod 81. The second fixing sleeve 8421 has a second through hole on its side wall near the second cleaning brush 83.

[0050] The first limiting rod 841 and the first fixing sleeve 8411 cooperate, and the second limiting rod 842 and the second fixing sleeve 8421 cooperate to restrict the movement direction of the connecting rod 81, preventing the connecting rod 81 from driving the first cleaning brush 82 to detach from the first filter plate 31 and the second cleaning brush 83 to detach from the second filter plate 41. This would prevent the first filter plate 31 and the second filter plate 41 from being cleaned, which may cause the first filter plate 31 or the second filter plate 41 to become clogged, resulting in water accumulation on the road and ultimately causing urban flooding.

[0051] Reference Figure 2 and Figure 3 A locking block 811 is fixedly connected to the bottom end of the connecting rod 81. When the end of the fixing rod 62 away from the mounting plate 61 is located at the end of the water pipe 1 closest to the outside, the locking block 811 abuts against the second fixing sleeve 8421. The locking block 811 cooperates with the second fixing sleeve 8421 to prevent the connecting rod 81 from disengaging from the second fixing sleeve 8421. At the same time, when the mounting plate 61 is pulled, all the branch rods 63 can be pulled out to the outside, and it can ensure that the debris on the multiple branch rods 63 can be cleaned.

[0052] Reference Figure 3 A support rod 9 is fixedly connected to the side wall of the connecting rod 81. There are two support rods 9, which are inclined and located below the first cleaning brush 82 and the second cleaning brush 83 respectively. The ends of the support rods 9 that are away from the connecting rod 81 are inclined upward and fixedly connected to the first cleaning brush 82 and the second cleaning brush 83 respectively.

[0053] The water flow impacts the first cleaning brush 82 and the second cleaning brush 83. The support rod 9 provides support for the cleaning brushes, increasing the service life of the first cleaning brush 82 and the second cleaning brush 83.

[0054] The operating principle of this application is as follows: During heavy rainfall, rainwater on the road enters the water pipe 1 and then flows into the transition trough 2. The rainwater in the transition trough 2 flows into the storage tank 5 through the first connecting pipe 3 and the second connecting pipe. Larger debris carried by the rainwater is blocked by the mounting plate 61 or the forked rod 63 to prevent it from entering the transition trough 2 and clogging the first filter plate 31 and the second filter plate 41. When there is a lot of debris, in order to prevent the debris from hindering the water flow, the mounting plate 61 can be removed by turning the bolt. The mounting plate 61 drives the fixed rod 62 to move, and the fixed rod 62 drives the forked rod 63 to move. After cleaning the debris on the forked rod 63, the mounting plate 61 can be reinstalled, reducing the occurrence of urban flooding.

[0055] When the mounting plate 61 is disassembled and moved, the fixing rod 62 drives the connecting rope 73 to move, the connecting rope 73 drives the connecting rod 81 to move, and the connecting rod 81 drives the first cleaning brush 82 and the second cleaning brush 83 to move. The first cleaning brush 82 cleans the first filter plate 31, and the second cleaning brush 83 cleans the second filter plate 41, preventing water accumulation in the transition groove 2 due to blockage of the first filter plate 31 and the second filter plate 41, thereby reducing the occurrence of urban flooding.

[0056] The embodiments described herein are preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Therefore, all equivalent changes made in accordance with the structure, shape, and principle of the present invention should be covered within the scope of protection of the present invention.
