Description

Technical Field

[0001] The present application relates to the technical field of waterlogging detection, and in particular to an urban waterlogging monitoring station. Background Art

[0002] As the most basic part of water information construction, water and rainfall conditions play an important role. In the process of urban waterlogging control, it is often necessary to monitor urban waterlogging points in real time, so as to better allocate urban water management resources and improve the work efficiency of water management departments. Generally, waterlogging is prone to form in urban tunnels and low-lying areas. When the rain is heavy and the water cannot be drained away in time, drivers or pedestrians do not understand the waterlogging situation and mistakenly enter the waterlogged area. The deep water may cause the vehicle to stall or cause personal injury. In serious cases, it may cause other severe incidents, which not only hinders people's travel, but also threatens people's lives and property safety.

[0003] Therefore, in some cities, radar or ultrasonic water level meters are used to monitor road waterlogging. This monitoring method requires the water level meter monitoring probe to be extended above the road surface to monitor road waterlogging. However, radar or ultrasonic water level meters are expensive and easily affected by the environment, which affects the detection accuracy. The subsequent maintenance cost is also high, and they cannot be widely used in every corner of the city.

[0004] In addition, there are also devices that use liquid pressure sensors, electronic water gauges and other liquid level sensors to monitor road water accumulation. This monitoring method has a low cost and can be laid in large quantities. However, during monitoring, it is necessary to drain the road water through a drainage pipe to the monitoring range of the liquid level sensor. Long-term use can easily cause silt and other debris to clog the drainage pipe, thereby affecting the accuracy of the monitoring data or even making it unusable. Especially in the early stages of urban waterlogging, there will be more floating objects and debris in the water, which will aggravate the blockage of the filter near the liquid level sensor. At the same time, different vehicles have different wading performance. When a vehicle passes through a flooded area or strong winds cause waves on the surface of the water, the surge on the surface of the water will also cause the liquid level sensor to detect inaccurately, resulting in the inability of subsequent vehicles to promptly obtain the accurate water accumulation situation, which may lead to traffic congestion caused by vehicle stalling or continuous waiting when forcing through. Summary of the invention

[0005] In order to improve the problem that the liquid level sensor is easily affected by debris and water surface surges when monitoring urban waterlogging, the present application provides an urban waterlogging monitoring station.

[0006] The urban waterlogging monitoring station provided in this application adopts the following technical solution: An urban waterlogging monitoring station comprises: Raise the base so that the vertical height of its top surface from the lowest point of the monitoring area is between 3cm and 10cm; A monitoring tube is fixedly connected to the upper end surface of the raised base, and a water inlet is opened around the bottom end of the monitoring tube; A filter screen is arranged at intervals on the outer circumference of the monitoring tube and completely covers the water inlet; A vortex baffle is fixedly connected in the monitoring tube, and the vortex baffle divides the inner cavity of the monitoring tube into a vortex channel; A liquid level sensor is arranged in the inner circle of the vortex baffle; Electronic warning display boards are installed outside the monitoring area; The controller is connected to both the liquid level sensor and the electronic warning display board, and is configured to control the electronic warning display board to at least display the water depth and water level change trend information according to the monitoring value of the liquid level sensor.

[0007] Furthermore, the controller is also connected to a timer, and the controller is also configured to calculate the amount of water level rise or fall per unit time based on the monitoring value of the liquid level sensor and the timing data of the timer.

[0008] Furthermore, the tops of the outer circle and the inner circle of the vortex baffle are arranged flush, and the height of the vortex baffle in the vertical direction tends to decrease along the spiral direction from the inner circle to the outer circle.

[0009] Furthermore, the inner arc side and / or the outer arc side of the vortex baffle is installed with a wave suppression plate arranged along the height direction thereof.

[0010] Furthermore, the wave suppression plate is flexibly mounted on the vortex baffle.

[0011] Furthermore, the wave suppression plate can be detachably mounted on the vortex baffle.

[0012] Furthermore, the width of the wave suppression plate along the radial direction of the monitoring tube is smaller than the width of the vortex channel.

[0013] Furthermore, a plurality of water inlets are provided around the bottom end of the monitoring tube, the filter screen is cylindrically arranged around the outer periphery of the monitoring tube, a floating ring is sleeved around the outer periphery of the filter screen, the floating ring rises as the water level rises, and a slag retaining plate is fixedly connected to the upper end face of the floating ring.

[0014] Furthermore, the inner peripheral wall of the floating ring is fixedly connected with bristles distributed in an annular manner on the outer periphery of the filter screen.

[0015] Furthermore, a bracket is fixedly connected to the bottom of the floating ring.

[0016] In summary, the beneficial technical effects of this application are: 1. By setting the main body of the waterlogging monitoring station of the present application on a raised base, the waterlogging monitoring station does not work in the early stage of waterlogging, which can effectively avoid the probability of impurities such as debris and dust on the road surface being mixed in the waterlogging in the early stage of waterlogging and aggravating the clogging of the filter, and can also avoid the probability of these debris adhering to the liquid level sensor with the waterlogging, thereby ensuring the service life of the liquid level sensor as much as possible and reducing the maintenance frequency; 2. When the depth of accumulated water in the monitored area rises, the accumulated water will cover the filter and enter the inner cavity of the monitoring tube through the water inlet on the monitoring tube. On the one hand, the debris in the accumulated water entering the monitoring tube can be filtered; on the other hand, the upper layer of accumulated water is mostly clear liquid, which can also reduce the impact on the service life of the liquid level sensor during contact monitoring with the liquid level sensor. Moreover, the accumulated water entering the inner cavity of the monitoring tube needs to pass through the vortex channel to spread to the liquid level sensor. Even if the accumulated water in the monitored area generates a large surge, the kinetic energy of these surges can be weakened as much as possible in the process of the accumulated water passing through the vortex channel, thereby ensuring the stability of the liquid level on the liquid level sensor located in the inner circle of the vortex baffle, so that the liquid level sensor can accurately and real-time measure the depth of water in the monitored area, thereby ensuring that the accumulated water depth information and water level change trend information displayed on the electronic warning display board are more accurate and will not be affected by passing vehicles or water surges; 3. By setting the vortex baffle to have a decreasing height in the vertical direction along the spiral direction from the inner circle to the outer circle, the deeper the water is, the greater the surge intensity on the water surface is, the greater the kinetic energy consumed by the surge passing through the vortex channel is, and the water flow is more stable when reaching the inner circle, thereby ensuring that the impact of the surge on the water on the accuracy of the monitoring results of the inner circle liquid level sensor can be reduced at different water depths; 4. The spirally shaped vortex baffle can cause the accumulated water to rotate when it flows in the vortex channel, increase the turbulence of the water flow, and help to precipitate and separate the suspended matter in the vortex channel, so that the suspended matter in the vortex channel can be discharged from the area below where the vortex baffle does not extend, thereby ensuring the cleanliness of the vortex channel as much as possible and reducing the probability of debris adhering to the liquid level sensor and affecting the detection accuracy.

[0019] The technical solution of the present application will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present application.

[0020] The present application embodiment discloses an urban waterlogging monitoring station. Figure 1 , Figure 2 and Figure 3 , which includes: The base 1 is raised, and the vertical height of its top surface from the lowest point of the monitoring area is between 3cm and 10cm, specifically 3cm, 5cm, 8cm, etc., and this value can be defined as a water accumulation safety value. When the water accumulation depth in the monitored area does not exceed the water accumulation safety value, it will not affect the passage of vehicles, and even a car can wade through slowly, with little impact on traffic. That is, when waterlogging occurs in the monitored area and the water accumulation depth is less than the water accumulation safety value, the waterlogging monitoring station of the present application will not work, which can reduce the processing volume of low-hazard information and ensure that urban resources are fully used in important places.

[0021] Specifically, the elevated base 1 is provided with: The monitoring tube 2 is fixedly connected to the upper end surface of the elevated base 1, and a water inlet 21 is opened around the bottom end thereof. The monitoring tube 2 can be made of stainless steel or engineering plastics; The filter screen 3 is arranged at intervals on the outer periphery of the monitoring tube 2 and completely covers the water inlet 21; specifically, the filter screen 3 can be a stainless steel wire mesh or a plastic mesh, and the mesh number of the filter screen 3 is preferably set to 50-200 meshes, and if the filter screen 3 is a soft mesh, a skeleton should be added to the inner circle of the filter screen 3 to maintain the overall shape of the filter screen 3; The vortex baffle 4 is fixedly connected to the monitoring tube 2, and the vortex baffle 4 divides the inner cavity of the monitoring tube 2 into a vortex channel 22; The liquid level sensor 5 is arranged in the inner circle of the vortex baffle 4. The liquid level sensor 5 can be a liquid pressure sensor or an electronic water gauge. In order to facilitate the setting and subsequent maintenance, in this embodiment, the liquid level sensor 5 is set as an electronic water gauge; The electronic warning display board 6 is arranged outside the monitoring area, such as at the entrance and exit of the tunnel, which can be a LED dot matrix display screen connected to the mains or equipped with a solar panel and a built-in battery; The controller is connected to both the liquid level sensor 5 and the electronic warning display board 6, and is configured to control the electronic warning display board 6 to at least display the water depth and water level change trend information according to the numerical value monitored by the liquid level sensor 5; the controller can specifically be a microcomputer, or a sub-controller integrating a communication module and a data acquisition module; and the controller can be set on the mounting frame of the electronic warning display board 6, at which time the controller is connected to the electronic warning display board 6 by wire and is wirelessly connected to the liquid level sensor 5.

[0022] After such arrangement, by setting the main body of the waterlogging monitoring station of the present application on the elevated base 1, the waterlogging monitoring station does not work in the early stage of waterlogging, which can effectively avoid the possibility of impurities such as debris and dust on the road surface being mixed into the accumulated water in the early stage of waterlogging and aggravating the probability of clogging of the filter 3, and can also avoid the probability of these debris adhering to the liquid level sensor 5 with the accumulated water, thereby ensuring the service life of the liquid level sensor 5 as much as possible and reducing the maintenance frequency.

[0023] When the depth of accumulated water in the monitored area rises, the accumulated water will cover the filter 3 and enter the inner cavity of the monitoring tube 2 through the water inlet 21 on the monitoring tube 2. On the one hand, the debris in the accumulated water entering the monitoring tube 2 can be filtered; on the other hand, the upper layer of the accumulated water is mainly clear liquid, which can also reduce the impact on the service life of the liquid level sensor 5 during the contact monitoring with the liquid level sensor 5. Moreover, the accumulated water entering the inner cavity of the monitoring tube 2 needs to pass through the vortex channel 22 to spread to the liquid level sensor 5. Even if the accumulated water in the monitored area generates a large surge, the kinetic energy of these surges can be weakened as much as possible during the process of the accumulated water passing through the vortex channel 22, thereby ensuring the stability of the liquid level on the liquid level sensor 5 located in the inner circle of the vortex partition 4, so that the liquid level sensor 5 can accurately and real-time measure the depth of accumulated water in the monitored area, thereby ensuring that the accumulated water depth information and water level change trend information displayed on the electronic warning display board 6 are more accurate and will not be affected by passing vehicles and water surges.

[0024] Furthermore, in order to provide passing vehicles and pedestrians with a more intuitive understanding of the water accumulation situation, the controller is also connected to a timer, and is further configured to calculate the amount of water level rise or fall per unit time according to the monitoring value of the liquid level sensor 5 and the timing data of the timer, and display the information on the electronic warning display board 6. Thus, citizens can not only intuitively obtain the water depth information through the electronic warning display board 6 to determine whether it is safe to pass, but also obtain the current rising or falling trend of the water depth to determine whether to pass immediately or wait for passage or change the route.

[0025] Furthermore, in other feasible embodiments, a rain gauge can be installed on the mounting frame of the electronic warning display, and the rain gauge can also be connected to the controller. Through the calculation of the controller, the water depth value of the monitored area in the future can be displayed on the electronic warning display board 6, and a travel suggestion can be given, such as it is expected that the water here will drop to the safe value in 5 minutes, please wait for passage. Alternatively, travel suggestions can be given based on meteorological information and with the help of large model prediction.

[0026] Considering that the deeper the water depth, the greater the surge intensity in the water and the more difficult it is for the water surface to return to calm, therefore, Figure 3 and Figure 4 , it is specially configured that the tops of the outer and inner circles of the vortex baffle 4 are flush with each other, and the height of the vortex baffle 4 in the vertical direction tends to decrease along the spiral direction from the inner circle to the outer circle, and the decreasing trend can be continuous or intermittent; in the embodiment of the present application, the decreasing trend is continuous, that is, the bottom end of the vortex baffle 4 is a curve that extends smoothly in a spiral downward.

[0027] After such arrangement, as the depth of water accumulation in the monitored area gradually increases, the distance that the water accumulates through the vortex channel 22 into the inner circle and contacts the liquid level sensor 5 gradually increases; that is, the deeper the water accumulation is, the greater the surge intensity on the water surface is, the greater the kinetic energy consumed by the surge passing through the vortex channel 22, and the water flow is smoother when reaching the inner circle, thereby ensuring that at different water accumulation depths, the influence of the surge on the water accumulation on the accuracy of the monitoring results of the inner circle liquid level sensor 5 can be reduced.

[0028] In addition, the spirally shaped vortex baffle can promote water rotation when the accumulated water flows in the vortex channel 22, increase the turbulence of the water flow, and help to precipitate and separate the suspended matter in the vortex channel 22, so that the suspended matter in the vortex channel 22 can be discharged from the area below it where the vortex baffle 4 does not extend, thereby ensuring the cleanliness of the vortex channel 22 as much as possible and reducing the probability of debris adhering to the liquid level sensor 5 and affecting the detection accuracy.

[0029] In addition, considering that the maximum wading depth of some conventional cars is 20-30 cm, the maximum wading depth of SUVs is 30-50 cm, and the maximum wading depth of off-road vehicles is 70-100 cm, considering practicality and cost issues, the overall length of the vortex baffle 4 in the embodiment of the present application is 70-80 cm, which can meet the high-precision detection of water depth in most cases.

[0030] At the same time, in order to further enhance the wave suppression effect in the vortex baffle 4, refer to Figure 3 and Figure 5 In other feasible embodiments, a wave suppression plate 41 arranged along the height direction can also be installed on the inner arc side and / or the outer arc side of the vortex baffle 4. Specifically, the wave suppression plate 41 is flexibly installed on the vortex baffle 4, and the wave suppression plate 41 can be detachably installed on the vortex baffle 4. The width of the wave suppression plate 41 along the radial direction of the monitoring tube 2 is smaller than the width of the vortex channel 22. In the specific setting, a plurality of sockets along the axial direction of the monitoring tube 2 are fixedly connected on the inner arc side of the vortex baffle 4, and a plug-in plugged into the socket is fixedly connected to the wave suppression plate 41, and the wave suppression plate 41 and the plug-in are flexibly connected through rubber.

[0031] In this way, the plurality of wave-suppressing plates 41 flexibly mounted on the vortex baffles 4 can further improve the energy of the surge that weakens the accumulated water flowing in the vortex channel 22 without causing a significant impact on the flow of the accumulated water in the vortex channel 22 .

[0032] In addition, it is also considered that there may still be suspended matter on the surface of the water, and it will rise with the increase of the depth of the water. Figure 2 and Figure 3 A plurality of water inlets 21 are provided around the bottom of the monitoring tube 2. The water inlets 21 are arranged along the axial direction of the monitoring tube 2, but not higher than the overall height of the vortex baffle 4. The filter screen 3 is arranged around the outer periphery of the monitoring tube 2 in a cylindrical shape. A floating ring 7 is sleeved around the outer periphery of the filter screen 3. The floating ring 7 rises with the rise of the water level. The upper end surface of the floating ring 7 is fixedly connected with a ring-shaped slag retaining plate 71. The floating ring 7 can be made of foam or airbags and has greater buoyancy in water. The inner wall of the floating ring 7 is fixedly connected with bristles 72 distributed in an annular manner around the outer periphery of the filter screen 3, and a bracket 73 is fixedly connected to the bottom of the floating ring 7.

[0033] In this way, even if the depth of accumulated water rises, the floating ring 7 can always follow the rise of the water level, and the slag retaining plate 71 arranged thereon can reduce the probability of suspended matter in the accumulated water passing through the filter screen 3 to a certain extent; moreover, when the surge of accumulated water hits the waterlogging monitoring station of the present application, the floating ring 7 first moves up and down on the filter screen 3 with the fluctuation of the water surface, thereby achieving the first wave suppression effect on the surge of accumulated water, and in this case, the bristles 72 on the inner side of the floating ring 7 can play a certain impact buffering effect on the one hand, and on the other hand, it will also wash the filter screen 3 with the fluctuation of the floating ring 7 on the water surface, so that the filter screen 3 can still be kept clean after the water recedes. The setting of the bracket 73 is to prevent the floating ring 7 and the brush from directly contacting the ground during the non-waterlogging period, and to extend its service life as much as possible.

[0034] The implementation principle of an urban waterlogging monitoring station in the embodiment of the present application is as follows: By setting the main body of the waterlogging monitoring station of the present application on a raised base 1, the waterlogging monitoring station does not work in the early stage of waterlogging. This can effectively avoid the possibility of impurities such as debris and dust on the road surface being mixed into the accumulated water in the early stage of waterlogging and aggravating the probability of clogging of the filter 3, and can also avoid the probability of these debris adhering to the liquid level sensor 5 with the accumulated water, thereby ensuring the service life of the liquid level sensor 5 as much as possible and reducing the maintenance frequency.

[0035] When the depth of accumulated water in the monitored area rises, the accumulated water will cover the filter 3 and enter the inner cavity of the monitoring tube 2 through the water inlet 21 on the monitoring tube 2. On the one hand, the debris in the accumulated water entering the monitoring tube 2 can be filtered; on the other hand, the upper layer of the accumulated water is mainly clear liquid, which can also reduce the impact on the service life of the liquid level sensor 5 during the contact monitoring with the liquid level sensor 5. Moreover, the accumulated water entering the inner cavity of the monitoring tube 2 needs to pass through the vortex channel 22 to spread to the liquid level sensor 5. Even if the accumulated water in the monitored area generates a large surge, the kinetic energy of these surges can be weakened as much as possible during the process of the accumulated water passing through the vortex channel 22, thereby ensuring the stability of the liquid level on the liquid level sensor 5 located in the inner circle of the vortex partition 4, so that the liquid level sensor 5 can accurately and real-time measure the depth of accumulated water in the monitored area, thereby ensuring that the accumulated water depth information and water level change trend information displayed on the electronic warning display board 6 are more accurate and will not be affected by passing vehicles and water surges.
