Description

Technical Field

[0001] This invention relates to the field of urban road surface drainage technology, and in particular to a drainage device that can also serve as a flood control barrier. Background Technology

[0002] Faced with extreme weather, existing urban pipe networks are insufficient to meet normal drainage needs, necessitating remedial measures to mitigate the disaster risks to underground buildings and structures. Flooding disasters affecting underground buildings and structures generally fall into two categories: channel flooding and wall seepage. Channel flooding is the primary cause of submersion. In my country, the common practice to ensure the safety of underground buildings and structures is to install linear drainage ditches to collect water and to have backup flood barriers to prevent additional rainwater intrusion. However, these measures prove somewhat inadequate in the face of heavy rainfall. The main reasons for this are: 1) the drainage ditch grates have limited capacity, leading to blockages and poor flow; 2) the intensity of the rainstorm exceeds the capacity of the drainage facilities; and 3) flood barriers are not activated promptly, often only after adverse effects have already occurred. Summary of the Invention

[0028] The following reference Figures 1 to 4 This invention describes a drainage device that can also serve as a flood control barrier.

[0029] An embodiment of the present invention provides a drainage device that can also serve as a flood control barrier, such as... Figures 1 to 4 As shown, the device includes a ditch body 100 and a rotatable grate plate 200. The ditch body 100 has an upward-facing opening, and a liftable rainwater tank 300 is disposed inside the ditch body 100. The rotatable grate plate 200 includes a frame 210, grate bars 220, a water-blocking membrane 230, a rotating part 240, and a driving component. The grate bars 220, the water-blocking membrane 230, and the rotating part 240 are disposed on the frame 210. The rotatable grate plate 200 is rotatably mounted on the opening via the rotating part 240. The driving component is disposed inside the ditch body 100 and drives the frame 210 to rotate relative to the opening. The rotating part 240 is disposed at one end of the frame 210, and the water-blocking membrane 230 is housed at the other end of the frame 210 away from the rotating part 240. When the rotatable grate plate 200 rotates and rises, the water-blocking membrane 230 falls under the action of gravity and covers the space between the grate bars 220 and the frame 210. The present invention discloses a drainage device that can also serve as a flood control barrier, comprising a ditch body 100 and a rotatable grate 200. The ditch body 100 has an upward-facing opening. The rotatable grate 200 includes a frame 210, grate bars 220, a water-blocking membrane 230, a rotating part 240, and a driving component. The rotatable grate 200 is rotatably mounted on the opening via the rotating part 240. The driving component is disposed within the ditch body 100. The rotating part 240 is disposed at one end of the frame 210. The water-blocking membrane 230 is housed at the other end of the frame 210 away from the rotating part 240. When the rotatable grate 200 rotates and rises, the water-blocking membrane 230 falls under gravity and covers the space between the grate bars 220 and the frame 210. The drive unit can drive the rotatable grate 200 to rotate and rise. After the rotatable grate 200 is raised, the water-blocking membrane 230 falls and covers the space between the grate bar 220 and the frame 210. At this time, the rotatable grate 200 can be used as a flood control barrier. The grate bar 220 and the water-blocking membrane 230 together can play a water-blocking function to prevent additional rainwater from entering the structure behind the ditch 100.

[0030] When there is no rainfall or during regular rainfall, surface runoff rainwater flows into the ditch 100 through the swivel grate 200. The rainwater flows over both sides of the rainwater tank 300 and slides down to the bottom of the drainage ditch before being discharged. At this time, the rainwater tank 300 is not filled with water, and the swivel grate 200 is fixed at the opening. When heavy rainfall occurs, surface runoff rainwater flows into the ditch 100 in large quantities through the rotatable grate 200. As the runoff rainwater volume exceeds the discharge flow of the drainage device, the water level in the ditch will continue to rise. When the liquid level in the drainage ditch continues to rise to a certain level (rainwater in the ditch can flow into the rainwater tank 300 from the side), the driving component drives the rotatable grate 200 to rotate relative to the opening. The rotatable grate 200 rises, and the water-blocking membrane 230 falls to cover the space between the grate strips 220 and the frame 210. The grate strips 220 and the water-blocking membrane 230 can play a water-blocking function to prevent additional rainwater from flowing into the building behind the ditch 100.

[0031] According to some embodiments of the present invention, a pulley block 500 and a warning lift plate 400 are also included. One end of the pulley block 500 is connected to the rainwater tank 300, and the other end of the pulley block 500 is connected to the warning lift plate 400. The rainwater tank 300 and the warning lift plate 400 are vertically and vertically disposed within the ditch body 100. The two ends of the pulley block 500 are respectively connected to the rainwater tank 300 and the warning lift plate 400. After a period of heavy rain, the water level in the ditch body 100 continuously rises. When rainwater begins to flow into the rainwater tank 300 from the side, the overall weight of the rainwater tank 300 continuously increases. Under the action of gravity, the rainwater tank 300 begins to move downwards into the ditch body 100. At this time, under the action of the pulley block 500... The warning lift plate 400 rises upward. The warning lift plate 400 is located on one side of the rotatable grate plate 200. It can cooperate with the drive component to lift the rotatable grate plate 200, so that the rotatable grate plate 200 rotates relative to the opening. After the rotatable grate plate 200 is raised, the water-blocking film 230 falls and covers the space between the grate bar 220 and the frame 210. At this time, the rotatable grate plate 200 can be used as a flood control baffle. The grate bar 220 and the water-blocking film 230 can play a water-blocking function to prevent additional rainwater from entering the interior of the structure behind the ditch body 100.

[0032] According to some embodiments of the present invention, the driving component includes a first telescopic arm 251, a second telescopic arm 252, and a sliding mechanism. The first telescopic arm 251 and the second telescopic arm 252 are respectively disposed on both sides of the trench 100. The sliding mechanism includes a slide rail 211 disposed on the rotatable grate 200 and a roller 212 movable relative to the slide rail 211. The first telescopic arm 251 and the second telescopic arm 252 are connected to the rotatable grate 200 through the sliding mechanism. The first telescopic arm 251 and the second telescopic arm 252 can extend or retract relative to the rotatable grate 200. The first telescopic arm 251 and the second telescopic arm 252 are respectively set on both sides of the ditch body 100. When the first telescopic arm 251 and the second telescopic arm 252 extend, they can lift the rotatable grate 200, causing the rotatable grate 200 to rotate relative to the opening. After the rotatable grate 200 is raised, the water-blocking film 230 falls and covers the space between the grate bar 220 and the frame 210. At this time, the rotatable grate 200 can be used as a flood control baffle. When the first telescopic arm 251 and the second telescopic arm 252 retract, the rotatable grate 200 is retracted to the opening, which can prevent debris from falling into the ditch body 100 through the opening. Specifically, in some embodiments, the slide rail 211 is welded and fixed to the rotatable grate 200, the roller 212 is rotatably mounted on the slide rail 211, and the first telescopic arm 251 and the second telescopic arm 252 are connected to the roller 212. The extension and retraction of the first telescopic arm 251 and the second telescopic arm 252 can drive the roller 212 to move relative to the slide rail 211, and the rotatable grate 200 is lifted or retracted during the extension and retraction of the first telescopic arm 251 and the second telescopic arm 252.

[0033] According to some embodiments of the present invention, a groove 231 is provided inside the frame 210, and a water-blocking film 230 is disposed inside the groove 231. A rotating part 240 is disposed at one end of the frame 210, and the water-blocking film 230 is housed at the other end of the frame 210 away from the rotating part 240. Specifically, a groove 231 is provided at the end of the frame 210 away from the rotating part 240. When the rotatable grate 200 is in a retracted state, the water-blocking film 230 is housed inside the groove 231. At this time, the rotatable grate 200 can drain water into the ditch 100 through the gap between the grate bars 220. When the rotatable grate 200 is in an extended state, the rotatable grate 200 rotates and rises. At this time, the water-blocking film 230 falls from the groove 231 under the action of gravity and falls to cover the space between the grate bars 220 and the frame 210, which can play a water-blocking function and prevent additional rainwater from entering the interior of the structure behind the ditch 100.

[0034] According to some embodiments of the present invention, the grate bars 220 are rotatably mounted on the frame 210 to ensure that the grate bars 220 are always facing downwards. The grate bars 220 can rotate relative to the frame 210. When the rotatable grate plate 200 is in the closed state, the grate bars 220 are facing downwards, and there are gaps between the grate bars 220. The rotatable grate plate 200 can drain water into the ditch body 100 through the gaps between the grate bars 220. When the rotatable grate plate 200 is in the open state, the grate bars 220 rotate under the action of gravity as the rotatable grate plate 200 rotates. At this time, the downward-facing grate bars 220 can stick together to play a water-blocking function, preventing additional rainwater from entering the structure behind the ditch body 100.

[0035] According to some embodiments of the present invention, the rainwater tank 300 includes a tank body 310 and a rain cover 320 disposed on the top. The tank body 310 is provided with water-absorbing material, and there is a gap between the rain cover 320 and the tank body 310 for rainwater to flow in. The rainwater tank 300 is vertically adjustable and installed inside the ditch 100. The rainwater tank 300 includes a tank body 310 and a rain cover 320 installed on top. The rain cover 320 guides rainwater into the ditch 100 for drainage. There is a gap between the rain cover 320 and the tank body 310 for rainwater to flow in. When heavy rainfall occurs, surface runoff rainwater flows into the ditch 100 in large quantities through the swivel grate 200. Since the runoff rainwater volume exceeds the discharge flow of the drainage device, the water level in the ditch will continue to rise. When the water level in the drainage ditch reaches the top of the rainwater tank 300, rainwater begins to flow into the rainwater tank 300 from the gap between the rain cover 320 and the tank body 310. At this time, the water-absorbing material inside the rainwater tank 300 begins to absorb water, and the overall weight of the rainwater tank 300 continues to increase.

[0036] According to some embodiments of the present invention, a liquid level detector is also provided inside the ditch body 100. With the liquid level detector installed in the ditch body 100, when the rainwater in the ditch body 100 reaches a certain level, the liquid level detector transmits a signal to the driving component. Upon receiving the signal, the driving component drives the rotatable grate 200 to rotate, automatically activating the flood control function of the rotatable grate 200 and enabling timely flood control and water blocking operations. The liquid level detector also serves as a synchronous alarm function, which is beneficial for transmitting flood information and facilitating flood control work. It is understood that in some embodiments, the driving component is a motor device.

[0037] According to some embodiments of the present invention, an electric latch 600 is also included. The electric latch 600 includes a first connecting portion disposed on the rotatable grate 200 and a second connecting portion disposed within the ditch body 100. The first connecting portion and the second connecting portion cooperate to fix the rotatable grate 200 onto the ditch body 100. When there is no rainfall or during normal rainfall, surface runoff rainwater flows into the ditch body 100 through the rotatable grate 200. The rainwater flows past both sides of the rainwater tank 300 and slides down to the bottom of the drainage ditch for discharge. At this time, the rainwater tank 300 is not filled with water, the electric latch 600 is in a normal locked state, the device is not operating, and the electric latch 600 locks the rotatable grate 200, locking the rotatable grate 200 at the opening. Specifically, the electric latch 600 includes a first connecting part disposed on the rotatable grate 200 and a second connecting part disposed within the ditch body 100. The first connecting part and the second connecting part cooperate to fix the rotatable grate 200 onto the ditch body 100. When heavy rain occurs, surface runoff rainwater flows into the drainage ditch through the rotatable grate 200. The rainwater flows over both sides of the rainwater tank 300 and slides down to the bottom of the drainage ditch, and is discharged through the rainwater pipe. At this time, the rainwater tank 300 is not filled with water, the electric latch 600 is in a normal locked state, and the device is not activated. When heavy rainfall occurs, surface runoff rainwater flows into the ditch body 100 in large quantities through the rotatable grate 200. Since the runoff rainwater volume exceeds the discharge flow rate of the drainage device, the water level in the ditch will continue to rise. When the water level in the drainage ditch continues to rise to a certain level, the electric latch 600 is triggered by an electrical signal to unlock and release an alarm signal. After the electric latch 600 is released, the drive unit drives the rotatable grate 200 to rotate relative to the opening, causing the rotatable grate 200 to rise. The water-blocking membrane 230 then falls and covers the space between the grate bars 220 and the frame 210. The grate bars 220 and the water-blocking membrane 230 effectively block water, preventing additional rainwater from entering the structures behind the ditch 100. The electric latch 600 also prevents the grate from opening abnormally, protecting the safety of nearby pedestrians and vehicles.

[0038] According to some embodiments of the present invention, a metal rod 232 is provided at the end of the water-blocking film 230. A driving component is provided inside the channel body 100, a rotating part 240 is provided at one end of the frame 210, and the water-blocking film 230 is housed at the other end of the frame 210 away from the rotating part 240. The metal rod 232 is provided at the end of the water-blocking film 230. When the rotatable grate 200 rotates, the water-blocking film 230 falls and covers the space between the grate strip 220 and the frame 210 under the gravity of the metal rod 232. Due to the weight of the metal rod 232 at the end, the water-blocking film 230 will not float under the impact of rainwater, thereby improving the water-blocking effect.

[0039] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention 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 the present invention.
