[0002] Smart city drainage devices are an important part of modern urban infrastructure. They are designed to effectively manage rainwater and wastewater discharge in cities to prevent urban flooding, protect the environment and ensure public safety. Especially during heavy rains, they can effectively reduce the risk of urban flooding, ensure smooth traffic and urban safety. In some low-lying areas, such as in bridge tunnels, drainage devices are mostly collection wells, which are set in the middle of the bridge tunnel and have grilles on the top to prevent garbage from entering the drainage system. During heavy rains, rainwater will flow to lower places due to gravity, and a large amount of rainwater will quickly accumulate in the bridge tunnel. The drainage capacity of the grille is small, and the drainage speed of the grille on the collection well is lower than the accumulation speed of rainwater in the bridge tunnel. The grille cannot effectively perform drainage operations, resulting in a large amount of rainwater accumulating in the bridge tunnel, making it impossible for vehicles to drive through the bridge tunnel, and then traffic is cut off.

DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0021] The drainage devices in bridge tunnels usually take the form of sump pits, which are placed in the middle of the tunnel and equipped with grilles on top. The purpose of this setting is to prevent garbage from entering the drainage system. When heavy rain comes, rainwater will flow to lower-lying areas due to gravity. At this time, a large amount of rainwater will accumulate in the tunnel in a short period of time. However, the drainage capacity of the grilles is limited and the drainage volume is small. The drainage speed of the grilles on the sump pits is much lower than the accumulation speed of rainwater in the tunnel, making it difficult for the grilles to effectively carry out drainage work, resulting in a large amount of rainwater accumulating in the tunnel, and vehicles cannot drive in the tunnel, eventually resulting in traffic interruption.

[0022] A smart city rainstorm emergency drainage device, such as Figure 1-Figure 4 As shown, it includes: a drainage mounting seat 1; a first screen 2, the drainage mounting seat 1 is fixedly connected to a first connecting piece, and the first screen 2 is slidably connected to the first connecting piece of the drainage mounting seat 1; a rotating sleeve 3, rotatably connected to the first connecting piece of the drainage mounting seat 1, and a spiral groove 4 is arranged in the rotating sleeve 3; a clamping block 5, fixedly connected to the first screen 2, and the clamping block 5 is slidably connected to the spiral groove 4; a circulation shell 6, rotatably connected in the drainage mounting seat 1; a driving assembly, arranged in the drainage mounting seat 1, and used to enable the circulation shell 6 to drive water to form a vortex.

[0023] In the above scheme, a liquid level monitoring device is provided in the bridge hole for monitoring the amount of rainwater accumulated in the bridge hole and its growth status. The upper side surface of the drainage mounting seat 1 is flush with the ground, and the drainage mounting seat 1 is connected to the underground urban drainage system. The first screen 2 is used for normal drainage operations during light and medium rains. During heavy rains, when the drainage flow rate of the first screen 2 is lower than the accumulation of rainwater in the bridge hole, the driving assembly drives the rotating sleeve 3 to rotate, so that the spiral groove 4 and the block 5 cooperate to drive the first screen 2 to move upward, thereby increasing the drainage aperture of the device, increasing the drainage flow rate, and avoiding continuous accumulation of water in the bridge hole, which makes it impossible for vehicles to drive in the bridge hole and causes traffic interruption.

[0024] Specifically, Figure 2 and Figure 5 As shown, the driving assembly includes: a servo motor 201, which is fixedly connected to the drainage mounting seat 1, the output shaft of the servo motor 201 is fixedly connected to a gear 202, the outside of the circulation shell 6 is fixedly connected to a gear ring 203, and the gear 202 is meshed with the gear ring 203; there are a plurality of guide plates 204, which are circumferentially arranged on the inner wall of the circulation shell 6; a docking assembly, which is arranged on the circulation shell 6, and is used to enable the rotating sleeve 3 to drive the first screen 2 to move upward.

[0025] In the above scheme, the servo motor 201 is a waterproof motor to prevent water vapor from corroding the internal electronic components. The servo motor 201 is electrically connected to the liquid level monitoring device to open or close the servo motor 201 according to the liquid level in the bridge hole. The guide plates 204 are tilted and evenly spaced on the inner wall of the circulation shell 6. The inclination angle and number of the guide plates 204 can be changed according to actual conditions. The circulation shell 6 drives the guide plates 204 distributed at equal intervals in the circumferential direction to rotate, so that the guide plates 204 drive the water to form vortices, thereby increasing the drainage rate and reducing the probability of the bridge hole being disconnected.

[0026] Specifically, Figure 2 and Figure 3 As shown, the drainage mounting seat 1 is spline-connected to the second screen 301 through the first connecting piece, and the two are in contact with each other, the second screen 301 is spline-connected to the first screen 2, and a gap is left between the tops of the two, the second screen 301 and the first screen 2 are both provided with a plurality of flow grooves, the plurality of flow grooves on the second screen 301 and the plurality of flow grooves on the first screen 2 are staggered, the second screen 301 is plugged and matched with the plurality of flow grooves on the first screen 2, the first screen 2 is plugged and matched with the plurality of flow grooves on the second screen 301, and the vertical length of the spiral groove 4 is greater than the gap between the second screen 301 and the first screen 2.

[0027] In the above scheme, the second screen 301 is flush with the ground and the upper plane of the drainage mounting seat 1 to ensure the stability of the vehicle when driving through the bridge tunnel. The gap distance between the second screen 301 and the first screen 2 can be changed according to actual conditions to ensure that small impurities carried in the rainwater will not be blocked between the two. When the first screen 2 moves upward, it fits with the second screen 301 to block the flow groove. The vertical length of the spiral groove 4 is greater than the gap between the second screen 301 and the first screen 2, so that the first screen 2 can drive the second screen 301 to move upward synchronously. There is an annular gap between the second screen 301 and the ground, so that rainwater only enters the drainage mounting seat 1 through the annular gap, and avoids the rainwater from entering the drainage mounting seat 1 from the flow groove and the water entering the annular gap. The rotational force of the guide plate 204 is difficult to form a stable vortex.

[0028] Specifically, Figure 3 and Figure 6 As shown, the docking assembly includes: a pushing block 401, a circulation shell 6 is fixedly connected to a second connecting piece, and the pushing block 401 is slidably connected to the second connecting piece on the circulation shell 6; an elastic element 402 is arranged between the pushing block 401 and the second connecting piece, and the rotating sleeve 3 is provided with a transmission groove 403, and the transmission groove 403 is limitedly matched with the pushing block 401, and the elastic force of the elastic element 402 is greater than the sum of the gravity of the first screen 2 and the gravity of the second screen 301.

[0029] In the above scheme, the push block 401 has two symmetrically distributed inclined surfaces, the elastic element 402 is a spring, and the outer surface is electroplated with an anti-rust coating to prevent its outer surface from rusting and causing its elasticity to decrease. The elastic element 402 is used to drive the push block 401 to dock with the transmission groove 403. The transmission groove 403 has symmetrically distributed inclined surfaces, and the inclined surfaces of the push block 401 and the transmission groove 403 cooperate with each other to facilitate the separation of the push block 401 and the transmission groove 403. The elastic force of the elastic element 402 is greater than the sum of the gravity of the first screen 2 and the gravity of the second screen 301, which is used to enable the push block 401 to drive the first screen 2 to move. The screen 2 and the second screen 301 move upward, and the gravity of the first screen 2 and the second screen 301 is less than the sliding resistance of the block 5 and the spiral groove 4, so that the first screen 2 and the second screen 301 are in a stable state after protruding out of the ground, and are not subject to sliding downward due to their own gravity. However, when subjected to external force, the first screen 2 and the second screen 301 will slide downward, and the second screen 301 will fit with the drainage mounting seat 1 again. When the vehicle is wading, the gravity of the vehicle presses the first screen 2 and the second screen 301 downward to fit with the ground, so that the vehicle can smoothly drive along the ground through the device, ensuring the safety of the vehicle wading.

[0030] When it starts to rain outside and the rainfall is small, the rainfall is less than the drainage capacity of the device, and the water in the bridge hole enters the drainage mounting seat 1 along the flow grooves on the second screen 301 and the flow grooves on the first screen 2, thereby completing the discharge of rainwater in the bridge hole. When the outside is in a rainstorm environment, the rainfall per unit time rises sharply, and the rainfall is greater than the drainage capacity of the device. At this time, water will gradually accumulate in the bridge hole, and the liquid level monitoring device in the bridge hole detects that the liquid level in the bridge hole reaches the preset value. At this time, the liquid level monitoring device sends a signal to the servo motor 201, and the servo motor 201 is turned on. At this time, the output shaft of the servo motor 201 drives the gear 202 to rotate, and the gear 202 passes through the gear ring 20 3 drives the circulation shell 6 to rotate, and the circulation shell 6 drives the pushing block 401 to rotate synchronously through the second connecting piece thereon, and the pushing block 401 drives the rotating sleeve 3 to rotate synchronously through the transmission groove 403, and the rotation of the rotating sleeve 3 drives the spiral groove 4 inside it to rotate synchronously, and the spiral groove 4 drives the first screen 2 to move upward through the clamping block 5 and contact with the second screen 301, and then the first screen 2 carries the second screen 301 to move upward synchronously, and the drainage mounting seat 1 is opened, so as to increase the drainage volume in the bridge hole, avoid the continuous accumulation of water in the bridge hole, make the bridge hole unable to drive vehicles, and cause traffic interruption, so as to slide to the top of the spiral groove 4, and the drainage mounting seat 1 is fully opened.

[0031] After the drainage mounting seat 1 is fully opened, the block 5 slides to the top of the spiral groove 4 and cannot move further, that is, the rotating sleeve 3 cannot rotate, and the circulation shell 6 still drives the push block 401 to continue to rotate through the second connecting piece, and the push block 401 squeezes the transmission groove 403, and the push block 401 slides along the second connecting piece, and the elastic element 402 is compressed at the same time, and this is done until the push block 401 is separated from the transmission groove 403, and this cycle is repeated, so that the circulation shell 6 continues to rotate. In this process, the circulation shell 6 drives a number of guide plates 204 distributed on its inner wall at equal intervals in the circumferential direction to rotate synchronously, so that the several guide plates 204 rotate to guide the water, so that the water in the bridge hole forms a vortex at the drainage mounting seat 1, thereby accelerating The speed at which water in the bridge hole enters the drainage mounting seat 1 is increased to improve the drainage rate and reduce the probability of the bridge hole being disconnected. When the first screen 2 carries the second screen 301 to move upward synchronously to open the drainage mounting seat 1, the first screen 2 and the second screen 301 are fitted together, and the flow grooves thereon are blocked with each other, so that the water in the bridge hole cannot enter the drainage mounting seat 1 through the first screen 2 and the second screen 301, and can only enter through the annular gap between the first screen 2 and the ground, thereby assisting the guide plate 204 to form a stable vortex, accelerating the discharge of water in the bridge hole, and avoiding the water from entering the drainage mounting seat 1 through the flow groove to collide with the water entering the annular gap, thereby making it difficult for the rotational force of the guide plate 204 to form a stable vortex.

[0032] In the process of the second screen 301 rising to drain water, the first screen 2 and the second screen 301 are always in a state higher than the drainage mounting seat 1. When a vehicle wades in the bridge hole, the tire of the vehicle has a probability of acting on the second screen 301. At this time, the second screen 301 moves downward under pressure, and the second screen 301 drives the first screen 2 to move downward synchronously. At this time, the first screen 2 drives the block 5 thereon to move downward synchronously, and the block 5 drives the rotating sleeve 3 to reset and rotate through the spiral groove 4, so that the second screen 301 is in contact with the drainage mounting seat 1, so that the vehicle can drive smoothly along the ground through the device to ensure the safety of the vehicle wading. When the wheel of the vehicle After the tire is separated from the second screen 301, the second screen 301 is not subjected to the force. During this process, the circulation shell 6 is always in a rotating state. Then the circulation shell 6 drives the push block 401 to rotate through the second connecting piece until it docks with the transmission groove 403. At this time, the elastic element 402 is reset. At this time, the push block 401 drives the rotating sleeve 3 to rotate through the transmission groove 403, so that the spiral groove 4 drives the first screen 2 to move upward again through the clamping block 5. The first screen 2 then pushes the second screen 301 to move synchronously, and the drainage mounting seat 1 is opened again for drainage. This is done until the clamping block 5 slides to the top of the spiral groove 4, and the push block 401 is separated from the transmission groove 403 again.

[0033] When the liquid level monitoring device in the bridge hole detects that the water discharge in the bridge hole is lower than the predetermined value, the liquid level monitoring device sends a signal to the servo motor 201, and the servo motor 201 rotates in the opposite direction, thereby causing the circulation shell 6 to drive the push block 401 to rotate in the opposite direction through the second connecting piece, until the push block 401 docks with the transmission groove 403. At this time, the push block 401 reverses and drives the rotating sleeve 3 to rotate synchronously, and the rotating sleeve 3 drives the internal spiral groove 4 to rotate synchronously, so that the spiral groove 4 drives the first screen 2 to reset to the initial state through the clamping block 5, and the second screen 301 resets to the initial state. When heavy rain occurs again, repeat the above steps.

[0034] In this embodiment, the connection between the guide plate 204 and the circulation shell 6 is a fixed connection, but it is limited to this embodiment. In other subsequent embodiments, the connection between the guide plate 204 and the circulation shell 6 is a sliding connection. Please refer to the specific description in the subsequent embodiments.

[0035] In a further embodiment, Figure 7 and Figure 8As shown, it also includes: a switching component, which is arranged on all the guide plates 204 and is used to replace different guide plates 204 to guide water, and the switching component includes: a transmission frame 501, which is the same in number as the guide plates 204 and is fixedly connected to adjacent guide plates 204, and all the guide plates 204 are slidably connected to the circulation shell 6; there are two rotating rings 502, which are slidably connected to the corresponding transmission frames 501; a power component, which is arranged in the drainage mounting seat 1, and is used to drive the two rotating rings 502 to move in opposite or reverse directions, and the side of the guide plate 204 close to the central axis of the first screen 2 has an arc surface matching the circulation shell 6.

[0036] In the above scheme, the number of guide plates 204 is even, which are divided into two groups. The two groups of guide plates 204 are cross-distributed. In the initial state, one group of guide plates 204 protrudes out of the circulation shell 6, and the other group of guide plates 204 cooperates with the inner wall of the circulation shell 6 to form a smooth arc surface. The two groups of guide plates 204 alternately protrude from the circulation shell 6 to guide rainwater to form vortices. When the guide plates 204 are recovered into the circulation shell 6, the circulation shell 6 will scrape off the garbage attached to the guide plates 204, so that it is carried into the drainage mounting seat 1 by the rainwater, so as to avoid the garbage blocking the circulation shell 6, reduce the water discharge speed, and cause the traffic to be unable to resume in time.

[0037] Specifically, Figure 6 and Figure 7 As shown, the power assembly includes: a trigger ring 503, which has two magnetic ones and are magnetically attracted to each other, and are respectively fixedly connected to the adjacent sides of the two rotating rings 502; a drainage mounting seat 1 is fixedly connected to a third connecting piece, and the third connecting piece on the drainage mounting seat 1 is fixedly connected to an electric push rod 504; an extrusion block 505, which is fixedly connected to the telescopic end of the electric push rod 504, and the two trigger rings 503 are extruded and matched with the extrusion block 505.

[0038] In the above scheme, the two trigger rings 503 have mutual attraction, which is used to drive the two rotating rings 502 to move in opposite directions. The two trigger rings 503 both have inclined surfaces, which are symmetrically distributed. The extrusion block 505 has symmetrically distributed inclined surfaces, and the inclined surfaces of the trigger rings 503 and the inclined surfaces of the extrusion block 505 fit each other. The electric push rod 504 is a waterproof push rod. The electric push rod 504 is electrically connected to the liquid level monitoring device so that it is turned on synchronously with the servo motor 201. The telescopic end of the push rod 504 drives the extrusion block 505 to squeeze the two trigger rings 503, so that the two trigger rings 503 move in opposite directions.

[0039] When the circulation shell 6 drives the several guide plates 204 distributed circumferentially inside it to rotate so that the water forms a vortex, since the drainage mounting seat 1 is in an open state, the first screen 2 and the second screen 301 do not have the function of blocking garbage. At this time, the garbage in the water will follow the water flow into the drainage mounting seat 1, and it is very easy to hang on the guide plate 204, affecting the stability of the vortex, and even blocking the circulation shell 6. At this time, the electric push rod 504 is turned on, and the telescopic end of the electric push rod 504 drives the extrusion block 505 thereon to slide toward its fixed part, and the extrusion block 505 squeezes the two trigger rings 503 to move backwards, thereby driving the two rotating rings 502 to move backwards synchronously, and the upper rotating ring 502 moves upward and drives the several transmission frames 501 distributed circumferentially thereon to move upward synchronously (at the same time, the transmission frame 501 slides along the adjacent rotating ring 502 to adapt to the change in the position of the guide plate 204), so that the transmission frame 501 drives the guide plate 204 to slide along the circulation shell 6, and then protrudes out of the inner wall of the circulation shell 6 to start to guide the water, and the transmission frame 501 located below The rotating ring 502 moves downward, causing the several transmission frames 501 distributed circumferentially thereon to move downward synchronously, thereby driving the adjacent guide plates 204 to slide and retract into the interior along the circulation shell 6, and then the electric push rod 504 is closed. At this time, the circulation shell 6 will scrape the outside of the guide plate 204, so that the garbage attached thereto is separated from the guide plate 204 and follows the water flow into the drainage mounting seat 1. After 10 minutes, the electric push rod 504 is turned on again, and the telescopic end of the electric push rod 504 drives the extrusion block 505 thereon to reset, and releases the extrusion of the two trigger rings 503. At this time, the two trigger rings 503 are magnetically attracted to each other, and the two trigger rings 503 drive the adjacent rotating rings 502 to move in opposite directions to reset, and then repeat the above steps. In this cycle, the guide plate 204 is periodically retracted into the circulation shell 6, so that the circulation shell 6 scrapes the garbage attached to the guide plate 204, ensures the circulation volume of the circulation shell 6, avoids garbage blocking the circulation shell 6, reduces the water discharge speed, and causes the traffic to be unable to resume in time.

[0040] The above is a detailed introduction to the present application. Specific examples are used in this article to illustrate the principles and implementation methods of the present application. The description of the above embodiments is only used to help understand the method of the present application and its core idea. At the same time, for general technical personnel in this field, according to the idea of ​​the present application, there will be changes in the specific implementation methods and application scope.
