Description

Technical Field

[0001] The present application relates to the technical field of urban waterlogging drainage, and in particular to an intelligent urban early warning waterlogging drainage system. Background Art

[0002] As the global climate warms, extreme weather becomes more frequent, and extreme rainfall tends to be more frequent and stronger. In today's rapidly developing cities, most of the original ponds, ditches, depressions, green spaces, etc. have been replaced by impermeable hardened surfaces such as buildings and roads, which has greatly weakened the surface's ability to absorb and retain rainwater, and most of the rainwater has to be drained away through the drainage system.

[0003] The drainage system consists of a main pipe and multiple branch pipes, and manhole covers are installed at the mouths of each branch pipe. Rainwater on city streets flows into the branch pipes through the manhole covers, and then the rainwater is collected in the main pipe and discharged into the river. When heavy rain occurs, rainwater is easily blocked in the branch pipes, causing waterlogging in city streets, thus paralyzing urban traffic and posing a great threat to people's lives and property. Summary of the invention

[0004] In order to reduce the risk of waterlogging in urban streets, this application provides an intelligent city early warning and drainage system.

[0005] The smart city early warning and drainage system provided in this application adopts the following technical solutions:

[0006] The intelligent city early warning drainage system comprises a main pipeline, a plurality of branch pipelines connected to the main pipeline, and a manhole cover provided on the branch pipeline, characterized in that: a water storage tank connected to the main pipeline is provided at the bottom of the branch pipeline, the plurality of water storage tanks are connected to each other, a drainage mechanism is provided on the water storage tank, and the drainage mechanism comprises:

[0007] A drainage pump, wherein the drainage pump is arranged in the water storage tank;

[0008] A drainage pipe, which is arranged on the drainage pump and is connected to the main pipeline;

[0009] A water level detector is arranged on the water storage tank and is electrically connected to a drainage pump. When the water level detector detects that the water level exceeds a specified value, the water level detector controls the drainage pump to start drainage.

[0010] By adopting the above technical solution, when there is less rain, the rainwater enters the branch pipe through the manhole cover, then enters the water storage tank and then enters the main pipe, and finally flows into the river; when there is more rain, the rainwater forms water accumulation in the branch pipe and the water storage tank. After the water level detector detects that the water level exceeds the specified value, the water level detector controls the drainage pump to start, and the water accumulated in the water storage tank is discharged into the main pipe through the drainage pipe. At the same time, the water flow discharged from the drainage pipe has a certain thrust, and the water flow pushes the water flow in the main pipe to move, thereby further accelerating the speed of water accumulation discharge, reducing the probability of waterlogging in urban streets, and thus reducing the probability of traffic paralysis and people's property losses;

[0011] At the same time, multiple water storage pools are interconnected, so the accumulated water is evenly distributed, which further reduces the probability of waterlogging in urban streets. When there is less rain, the drainage pump stops running, thereby achieving energy-saving and environmental protection effects.

[0012] Optionally, a crushing mechanism is provided on the water storage tank, and the crushing mechanism comprises:

[0013] A stirring rod, which is rotatably disposed on the water storage tank and extends into the branch pipe;

[0014] A crushing piece, which is arranged on a crushing rod located in the branch pipe and is used to crush impurities;

[0015] A driving assembly is arranged on the water storage tank and is used for driving the smashing rod to rotate.

[0016] By adopting the above technical solution, impurities such as branches mixed in rainwater enter the branch pipe, and the driving component starts to drive the pulverizing rod to rotate. The rotation of the pulverizing rod drives the pulverizing pieces to rotate to pulverize the impurities, thereby reducing the probability of impurities entering the drainage pump and reducing the drainage effect after the drainage pump is damaged, thereby improving the drainage effect of the drainage pump, and further reducing the probability of waterlogging in urban streets.

[0017] At the same time, when the churning rod rotates, the accumulated water in the branch pipe will cause a vortex. When too much water spreads to the top of the manhole cover, the vortex will extend to the top of the manhole cover with the accumulated water. The vortex will drive the impurities accumulated on the manhole cover to move, reducing the probability of impurities blocking the water flow of the manhole cover. The vortex will also speed up the water flow, thereby further speeding up the flow rate, thereby reducing the probability of waterlogging in urban streets.

[0018] Optionally, the driving component includes:

[0019] A water drum, which is arranged on the water storage tank and has a water cavity;

[0020] A rotating rod, which is rotatably disposed on the water drum and extends into the water cavity and is connected to the stirring rod;

[0021] A rotating sheet, wherein the rotating sheet is arranged on a rotating rod located in the water chamber and a plurality of the rotating sheets are arranged in a circular array around the axis of the rotating rod;

[0022] A water inlet pipe and a water outlet pipe, the water inlet pipe and the water outlet pipe are arranged on the water drum and are both connected to the water cavity, the water inlet pipe is connected to the drainage pump and the inner diameter is smaller than the inner diameter of the drainage pipe, the water inlet pipe and the water outlet pipe are both provided with a first one-way valve, the first one-way valve allows the water flow in the water inlet pipe to only enter the water cavity and the water flow in the water outlet pipe to only flow out of the water cavity, and the water outlet pipe is connected to the main pipeline.

[0023] By adopting the above technical solution, the drainage pump is started, and part of the water flows into the water chamber through the water inlet pipe. The water flow drives the rotating plate to rotate, and the rotation of the rotating plate drives the rotating rod and the crushing rod to rotate. Then the water flow is transported to the main pipeline through the outlet pipe for output, so as to realize the rotation of the crushing rod. At the same time, the one-way valve makes the water flow direction constant, thereby reducing the probability of reducing the driving force on the crushing rod due to the reversal of water flow, thereby increasing the driving force on the crushing rod, improving the crushing effect of impurities, and reducing the probability of waterlogging in urban streets.

[0024] There is rainwater in the branch pipes and the water storage tank, so setting up a driving source such as a driving motor will be easily damaged. The water flow pumped out by the drainage pump drives the pulverizing rod to rotate, so there is no need to use an additional driving source to drive the pulverizing rod to rotate, thereby improving the convenience of driving the pulverizing rod to rotate.

[0025] Optionally, the water cavity is annular and its axis coincides with the axis of the rotating rod, and the plurality of rotating sheets abut against the side wall of the water cavity and divide the water cavity into a plurality of independent water inlet spaces.

[0026] By adopting the above technical solution, rainwater enters the water cavity through the water inlet pipe, and thus the rainwater enters an independent water inlet space, thereby reducing the probability of rainwater flowing without contacting the rotating plate, and improving the pushing effect of rainwater on the crushing rod. Therefore, a smaller water flow can achieve a larger thrust on the crushing rod, thereby improving the crushing effect on impurities and reducing the probability of waterlogging in urban streets.

[0027] Optionally, a water diversion assembly is provided on the water inlet pipe, and the water diversion assembly includes:

[0028] A water receiving pipe, which is arranged on the water inlet pipe and vertically upwards, and is provided with a second one-way valve that allows water in the water receiving pipe to only flow into the water inlet pipe;

[0029] A water receiving tray is arranged on the top of the water receiving pipe and is annular in shape and receives water flow in the branch pipe.

[0030] By adopting the above technical scheme, the water receiving tray receives the water flow in the branch pipe, and the water flows into the water cavity through the water receiving pipe and the water inlet pipe to push the stirring rod to rotate, and then the water flows into the main pipe through the water outlet pipe for transportation. Therefore, the water flow entering the water receiving pipe and the water inlet pipe through the drainage pump simultaneously pushes the stirring rod to rotate, and when the drainage pump stops running, the water flow in the water receiving pipe can continue to push the stirring rod to rotate, thereby further improving the stirring effect of the stirring rod on impurities, and at the same time, the water flow in the branch pipe is guided to the main pipe for transportation through the water receiving tray, the water inlet pipe and the water outlet pipe, thereby further improving the discharge effect of the accumulated water and reducing the probability of waterlogging in urban streets.

[0031] Optionally, the water receiving tray is provided with a first guide ring and a second guide ring for guiding the water flow into the water receiving tray, a positioning ring is provided in the water receiving tray, and a filter ring for filtering the water flow is placed on the positioning ring.

[0032] By adopting the above technical scheme, the filter ring filters the water flow, thereby reducing the probability of impurities causing blockage in the water cavity, and the filter ring is removed for cleaning, and then placed on the positioning ring after cleaning, so as to improve the filtering effect of the water flow, thereby further increasing the driving force of the water flow on the stirring rod, thereby further improving the discharge effect of the accumulated water and reducing the probability of waterlogging in urban streets.

[0033] Optionally, the crushing rod is detachably connected to the lower surface of the manhole cover and the top end of the rotating rod through a connecting assembly, and the connecting assembly includes:

[0034] A plug-in block, which is arranged on the mashing rod and is plugged and matched with the top end of the rotating rod;

[0035] A rotating sleeve is rotatably arranged on the lower surface of the well cover, and the top end of the stirring rod is plugged and installed on the rotating sleeve.

[0036] By adopting the above technical scheme, when the staff needs to enter the branch pipe and the water storage pool, they remove the manhole cover to drive the rotating sleeve to disengage from the churning rod, then place the manhole cover on the ground, then pull the top of the churning rod to drive the plug-in block to disengage from the rotating rod, and then place the churning rod on the ground, so as to realize the disassembly of the churning rod. Then the staff can enter the branch pipe for cleaning. After the cleaning is completed, the staff moves out the branch pipe, then places the churning rod into the branch pipe, and plugs the plug-in block into the rotating rod, then covers the manhole cover on the pipe mouth of the branch pipe, and makes the top of the churning rod be sleeved on the connecting sleeve.

[0037] Therefore, the top end of the crushing rod extends to the lower surface of the manhole cover, so that the crushing range of the crushing rod and crushing pieces is maximized when crushing impurities, and the two ends of the crushing rod are supported and positioned by the connecting sleeve and the rotating rod respectively, so as to improve the stability of the crushing pieces during crushing, thereby improving the crushing effect of impurities, and the crushing rod is detachable, thereby improving the convenience of workers entering the branch pipeline, thereby reducing the probability of urban street waterlogging, and also improving the convenience of workers entering the branch pipeline.

[0038] Optionally, a flood alarm is provided on the lower surface of the manhole cover, and a support plate is provided on the ground, on which a display screen electrically connected to multiple flood alarms is provided, and the display screen is used to display location information of the flood alarm and to warn pedestrians and vehicles.

[0039] By adopting the above technical solution, when the accumulated water submerges the flood alarm, the flood alarm will transmit information to the display screen, and the display screen will display the submerged location, thereby raising the attention of pedestrians and vehicles and providing early warning, thereby further reducing the probability of causing traffic paralysis and property loss to the people.

[0040] Optionally, a protection mechanism is provided on the branch pipe and between the manhole cover and the crushing fragments, and the protection mechanism includes:

[0041] A protective ring, wherein the protective ring is arranged on the inner wall of the branch pipe;

[0042] A protective net, wherein the protective net frame is set up on the protective ring and is used to catch pedestrians.

[0043] By adopting the above technical solution, the protective net is set up on the protective ring, and the protective net protects pedestrians, thereby reducing the probability of pedestrians falling after the manhole cover is damaged or pedestrians coming into contact with debris, thereby improving pedestrian safety.

[0044] Optionally, the protective net is provided with protective columns which are plugged into and installed on the protective ring.

[0045] By adopting the above technical solution, the protective column is plugged and installed on the protective ring, thereby reducing the probability of slippage of the protective net, thereby further improving the protective effect on pedestrians.

[0046] In summary, the present application includes at least one of the following beneficial technical effects:

[0047] When rainwater enters the water storage tank and the water level detector detects that the water level exceeds the specified value, the drainage pump starts and the accumulated water in the water storage tank is discharged into the main pipeline through the drainage pipe. At the same time, the water flow discharged from the drainage pipe has a certain thrust, and the water flow pushes the water flow in the main pipeline to move, thereby further speeding up the discharge of accumulated water and reducing the probability of waterlogging in urban streets, thereby reducing the probability of traffic paralysis and people’s property loss.

The water pipe 13 is connected to the main pipeline 1 and is used for drainage; a mounting ring 14 is fixedly installed on the top of each branch pipeline 11, and a manhole cover 15 is covered on the upper surface of the mounting ring 14. At the same time, the upper surface of the manhole cover 15 is flush with the ground, and a plurality of through holes 16 for water supply are opened on the upper surface of the manhole cover 15.

[0059] Reference Figure 2 and Figure 3 The drainage mechanism 2 includes a drainage pump 21, a drainage pipe 22 and a water level detector 23. The drainage pump 21 is fixedly installed on the inner wall of the water storage tank 12, and the drainage pipe 22 is fixedly installed on the drainage pump 21. The end of the drainage pipe 22 away from the drainage pump 21 is inclined downward and fixedly connected to the upper surface of the main pipe 1. At the same time, the drainage pipe 22 is inclined toward the flow direction of rainwater in the main pipe 1, and the drainage pipe 22 is connected to the main pipe 1. When the drainage pump 21 is started, the accumulated water in the water storage tank 12 enters the main pipe 1 through the drainage pipe 22.

[0060] Reference Figure 2 and Figure 3 The water level detector 23 is fixedly installed on the inner wall of the water storage tank 12 and is located near the top of the water storage tank 12. At the same time, the water level detector 23 is connected to the control panel and is located above the drainage pump 21. Therefore, the water level detector 23 detects the water level in the water storage tank 12; when there is too much water in the water storage tank 12 and submerges the water level detector 23, the water level detector 23 detects the water level in the water storage tank 12. When the water level in the water storage tank 12 exceeds the specified value, the water level detector 23 controls the drainage pump 21 through the control panel to start drainage.

[0061] Reference Figure 1 and Figure 4A flood alarm 31 is fixedly installed on the lower surface of each manhole cover 15, and a vertical support plate 32 is fixedly installed on the upper surface of the ground. A display screen 33 electrically connected to multiple flood alarms 31 is fixedly installed on the support plate 32. The display screen 33 is used to display the position information of the flood alarm 31 submerged by water. When the accumulated water overflows to the lower surface of the manhole cover 15, the accumulated water submerges the flood alarm 31, and the display screen 33 displays the position information of the flood alarm 31, so as to warn drivers and vehicles of water accumulation.

The driving assembly 5 comprises a water drum 51, a rotating rod 52, a rotating piece 53, a water inlet pipe 54 and a water outlet pipe 55. The water drum 51 is fixedly mounted on the upper surface of the supporting plate 32, and the water drum 51 is in the shape of a round drum and its axis coincides with the axis of the stirring rod 41. At the same time, an annular water cavity 56 is coaxially provided inside the water drum 51; the rotating rod 52 is coaxially rotatably mounted on the upper surface of the water drum 51, and the bottom end of the rotating rod 52 extends into the water cavity 56 and contacts with the inner bottom wall of the water cavity 56; one end of the rotating piece 53 is fixedly mounted on the rotating rod 52, and the rotating piece 53 is located inside the water cavity 56. At the same time, a plurality of rotating pieces 53 are arranged in a circular array around the axis of the rotating rod 52, and the side walls of the plurality of rotating pieces 53 that are not in contact with the rotating rod 52 contact with the side walls of the water cavity 56 respectively, so that the plurality of rotating pieces 53 divide the water cavity 56 into a plurality of independent water inlet spaces.

[0064] Reference Figure 2 and Figure 5The water inlet pipe 54 and the water outlet pipe 55 are fixedly installed on the outer wall of the water drum 51 and are respectively located on both sides of the rotating rod 52. At the same time, the water inlet pipe 54 and the water outlet pipe 55 are both connected to the water cavity 56, and the inner diameter of the water inlet pipe 54 is smaller than the inner diameter of the drain pipe 22. A three-way pipe 24 is fixedly installed on the drainage pump 21, and the end of the water inlet pipe 54 away from the water drum 51 and the end of the drain pipe 22 away from the main pipeline 1 are both fixedly connected to the three-way pipe 24.

[0067] Reference Figure 3 and Figure 5 When the drainage pump 21 is started to drain water, water flows into the water chamber 56 through the water inlet pipe 54, and the water flows to drive the rotating piece 53 to rotate. The rotation of the rotating piece 53 drives the rotating rod 52 and the crushing rod 41 to rotate. The rotation of the crushing rod 41 drives the crushing pieces 42 to rotate to crush the impurities, and then the water flows out through the water outlet pipe 55, thereby crushing the impurities.

[0068] Reference Figure 3 and Figure 5A water diversion assembly 7 is provided on the water inlet pipe 54, and the water diversion assembly 7 includes a water receiving pipe 71 and a water receiving tray 72. The water receiving pipe 71 is fixedly installed on the upper surface of the water inlet pipe 54, and the water inlet pipe 54 extends vertically upward to above the water inlet pipe 54 and the water drum 51. At the same time, a second one-way valve 73 is also fixedly installed on the water receiving pipe 71, and the second one-way valve 73 allows the water flow in the water receiving pipe 71 to only enter the water inlet pipe 54; the water receiving tray 72 is fixedly installed on the top of the water receiving pipe 71, and the water receiving tray 72 is annular. At the same time, the axes of the water receiving tray 72 and the crushing rod 41 coincide, and the crushing rod 41 passes through the water receiving tray 72.

[0069] Reference Figure 2 and Figure 5 The water receiving tray 72 receives the rainwater falling from the branch pipe 11, and then the rainwater enters the water inlet pipe 54 through the water receiving pipe 71 to push the rotating piece 53 to rotate.

[0072] The working principle of the embodiment of the present application is as follows:

[0073] Rainwater falls into the branch pipe 11 through the through hole 16 on the manhole cover 15, and then falls into the water storage tank 12 for storage. At the same time, the rainwater in the water storage tank 12 enters the main pipe 1 through the water pipe 13, and finally flows into the river. The water level detector 23 detects the water level. When the water level exceeds the specified value, the drainage pump 21 starts, and the rainwater in the water storage tank 12 enters the main pipe 1 through the drainage pipe 22. At the same time, the rainwater pushes the rainwater in the main pipe 1 to move, thereby accelerating the drainage effect, thereby reducing the probability of waterlogging in urban streets. At the same time, when the rainwater submerges the flood alarm 31, the position data of the flood alarm 31 is input into the display screen 33 for display, so as to warn pedestrians and vehicles, thereby reducing the probability of traffic paralysis and people's property loss.

[0074] Part of the rainwater in the drain pipe 22 enters the water inlet pipe 54, and at the same time the rainwater falls into the water receiving tray 72, and then the rainwater enters the water inlet pipe 54 and mixes with the rainwater in the drain pipe 22. The rainwater drives the crushing pieces 42 to rotate and crush the impurities, thereby reducing the probability that the impurities block the drain pump 21 and reduce the drainage effect, thereby improving the drainage effect and reducing the probability of causing traffic paralysis and people’s property losses.

[0075] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
