Description

TECHNICAL FIELD

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

[0002] As a most basic part of water information construction, water regime plays 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, in urban tunnels and low-lying areas, waterlogging is easy to form. When the rain is heavy and the water cannot be drained in time, due to the lack of understanding of the waterlogging situation by drivers or pedestrians, they may enter the waterlogging area, and the deep water may cause the vehicle to stall or the person to be injured, and in severe cases, other adverse events may occur, which not only hinders people's travel, but also threatens people's life and property safety.

[0003] Therefore, in some cities, radar or ultrasonic water level meters are used to monitor the road waterlogging, the water level meter monitoring probe needs to be extended above the road surface to monitor the road waterlogging, but the cost of the radar or ultrasonic water level meter is high and the detection accuracy is easily affected by the environment, and the maintenance cost is also high in the later period, so it cannot be widely applied in every corner of the city.

[0004] In addition, there are also devices for monitoring road waterlogging by using liquid pressure sensors, electronic water gauges and other liquid level sensors. The monitoring method has low cost and can be widely laid, but it needs to guide the road waterlogging to the monitoring range of the liquid level sensor through a drainage pipe, and long-term use may cause the drainage pipe to be blocked by silt and other debris, thereby affecting the accuracy of the monitoring data, and even the device cannot be used. Especially in the initial stage of waterlogging, there are many floating objects and debris in the water, which may exacerbate the blocking of the filter screen near the liquid level sensor; at the same time, different vehicles have different water performance, when a vehicle passes through the waterlogging place or the water surface is caused by the wind, the water surface surge may also cause the liquid level sensor to detect inaccurately, so that the subsequent vehicles cannot learn the accurate waterlogging situation in time, thereby causing the traffic congestion phenomenon caused by the vehicle stalling or continuous waiting when forcibly passing through. SUMMARY

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

[0006] The urban waterlogging monitoring station provided by the application adopts the following technical scheme:

[0007] An urban waterlogging monitoring station comprises:

[0008] The top surface of the base is 3-10 cm higher than the lowest point of the monitoring area.

[0009] The monitoring cylinder is fixed to the top surface of the base, and a water inlet is formed on the bottom periphery of the monitoring cylinder.

[0010] The filter screen is arranged on the periphery of the monitoring cylinder and completely covers the water inlet.

[0011] The vortex baffle is fixed in the monitoring cylinder, and the vortex baffle divides the inner cavity of the monitoring cylinder into a vortex channel.

[0012] The liquid level sensor is arranged in the inner ring of the vortex baffle.

[0013] The electronic early warning display board is arranged on the periphery of the monitoring area.

[0014] The controller is connected to the liquid level sensor and the electronic early warning display board, and is configured to control the electronic early warning display board to display at least the water depth and the water level change trend information according to the monitoring value of the liquid level sensor.

[0015] Further, the controller is also connected to a timer, and the controller is also configured to calculate the water level rise or fall amount per unit time according to the monitoring value of the liquid level sensor and the timer data.

[0016] Further, the top of the outer ring and the inner ring of the vortex baffle is arranged in the same plane, and the height of the vortex baffle in the vertical direction decreases along the spiral direction from the inner ring to the outer ring.

[0017] Further, the inner arc side and / or the outer arc side of the vortex baffle is provided with a wave suppression plate arranged along the height direction thereof.

[0018] Further, the wave suppression plate is flexibly mounted on the vortex baffle.

[0019] Further, the wave suppression plate is detachably mounted on the vortex baffle.

[0020] Further, the width of the wave suppression plate in the radial direction of the monitoring cylinder is smaller than the width of the vortex channel.

[0021] Further, a plurality of water inlets are formed on the bottom periphery of the monitoring cylinder, the filter screen is arranged in the form of a cylinder around the periphery of the monitoring cylinder, a floating ring is arranged around the periphery of the filter screen, the floating ring rises with the rise of the water level, and a slag baffle is fixed to the upper end surface of the floating ring.

[0022] Further, the inner wall of the floating ring is fixed with bristles arranged in a ring around the periphery of the filter screen.

[0023] Furthermore, a bracket is fixedly connected to the bottom of the floating ring.

[0024] In summary, the beneficial technical effects of this application are:

[0025] 1. By placing the main body of the waterlogging monitoring station of the present application on a raised base, the waterlogging monitoring station is not operated in the early stage of waterlogging. This can effectively prevent impurities such as debris and dust on the road surface from being mixed into the accumulated water in the early stage of waterlogging, thereby increasing the probability of filter clogging. It can also prevent the probability of such debris adhering to the liquid level sensor with the accumulated water, thereby maximizing the service life of the liquid level sensor and reducing the maintenance frequency.

[0026] 2. When the depth of accumulated water in the monitored area rises, the accumulated water will overflow the filter and enter the inner cavity of the monitoring tube through the water inlet on the monitoring tube. On the one hand, it can filter out the debris in the accumulated water entering the monitoring tube; on the other hand, the upper layer of the 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 before it can 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 during 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 in real time measure the depth of the 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 are more accurate and will not be affected by passing vehicles or water surges.

[0027] 3. By setting the vortex baffles so that their vertical height decreases along the spiral direction from the inner ring to the outer ring, the deeper the water, the greater the surge intensity at the water surface. This surge consumes more kinetic energy as it passes through the vortex channel, and the water flow is smoother when it reaches the inner ring. This ensures that the impact of the surge on the monitoring results of the inner ring liquid level sensor is reduced at different water depths.

[0028] 4. The spiral-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 it 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.

[0042] The following will clearly and completely describe the technical solution of this application in conjunction with the accompanying drawings. Obviously, the embodiments described are only part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of this application.

[0043] The present application embodiment discloses an urban waterlogging monitoring station. Figure 1 、 Figure 2 and Figure 3 , which includes:

[0044] 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 slowly wade through the water, which has 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 this application will not work, which can reduce the processing volume of low-hazard information and ensure that urban resources are fully utilized in important places.

[0045] Specifically, the cushion base 1 is provided with:

[0046] The monitoring cylinder 2 is fixed to the upper end surface of the cushion base 1, and a water inlet 21 is formed in the bottom end of the peripheral side of the monitoring cylinder 2. The monitoring cylinder 2 can be made of stainless steel or engineering plastic.

[0047] The filter screen 3 is arranged at intervals on the outer periphery of the monitoring cylinder 2 and completely covers the water inlet 21. Specifically, the filter screen 3 can be a stainless steel screen or a plastic screen. The mesh number of the filter screen 3 is preferably 50-200 meshes. If the filter screen 3 is a soft screen, a framework should be added to the inner circle of the filter screen 3 to maintain the overall shape of the filter screen 3.

[0048] The vortex baffle 4 is fixed in the monitoring cylinder 2, and the vortex baffle 4 divides the inner cavity of the monitoring cylinder 2 into a vortex channel 22.

[0049] 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 installation and maintenance in the later period, the liquid level sensor 5 is set as an electronic water gauge in this embodiment.

[0050] The electronic early warning display board 6 is arranged on the periphery of the monitoring area, such as at the entrance and exit of the tunnel. Specifically, it can be an LED dot matrix display screen, which is connected to the power grid or provided with a solar panel and an internal battery.

[0051] The controller is connected to the liquid level sensor 5 and the electronic early warning display board 6, and is configured to control the electronic early warning display board 6 to display at least the water depth and water level change trend information according to the monitoring value of the liquid level sensor 5. The controller can be a microcomputer or a sub-controller integrated with a communication module and a data acquisition module. The controller can be arranged on the mounting bracket of the electronic early warning display board 6. At this time, the controller is connected to the electronic early warning display board 6 by wire and connected to the liquid level sensor 5 wirelessly.

[0052] After such arrangement, the waterlogging and accumulated water monitoring station body of the present application is arranged on the cushion base 1, so that the waterlogging and accumulated water monitoring station does not work in the initial stage of water accumulation. This can effectively avoid the probability of aggravating the blockage of the filter screen 3 due to the mixing of impurities such as dirt and dust on the road surface in the initial stage of water accumulation, and also can avoid the probability of these impurities adhering to the liquid level sensor 5 with the water accumulation, so as to ensure the service life of the liquid level sensor 5 as much as possible and reduce the maintenance frequency.

[0053] When the water depth of the monitored area rises, the water overflows the filter screen 3 and enters the inner cavity of the monitoring cylinder 2 through the water inlet 21 on the monitoring cylinder 2. On the one hand, the impurities in the water entering the monitoring cylinder 2 can be filtered. On the other hand, the upper layer of the water is mainly clear liquid, which can reduce the impact on the service life of the liquid level sensor 5 during the contact monitoring process. Moreover, the water in the inner cavity of the monitoring cylinder 2 needs to pass through the vortex channel 22 to spread to the liquid level sensor 5. Even if the water in the monitored area produces large surges, the kinetic energy of these surges can be weakened as much as possible during the water passing through the vortex channel 22, so as to ensure the stability of the liquid level on the liquid level sensor 5 in the inner circle of the vortex partition plate 4, so that the liquid level sensor 5 can accurately and real-timely measure the water depth of the monitored area, thereby ensuring that the water depth information and water level change trend information displayed on the electronic early warning display board 6 are more accurate and are not affected by the passing vehicles and water surges.

[0054] Moreover, in order to give the passing vehicles and pedestrians a more intuitive waterlogging situation, the controller is further connected with a timer, and the controller is further configured to calculate the water level rise or drop amount 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 early warning display board 6. Therefore, citizens can not only intuitively obtain the water depth information through the electronic early warning display board 6 to judge whether it is safe to pass, but also can obtain the current rising or falling trend of the water depth to judge whether to pass immediately or wait to pass or change the route.

[0055] Further, in other feasible embodiments, a rain gauge can also be installed on the mounting frame of the electronic early warning display, and the rain gauge is also connected with the controller. Through the calculation of the controller, the water depth value of the monitored area in a future period of time can also be displayed on the electronic early warning display board 6, and a passing suggestion can be given, such as the water depth in this place is expected to drop to a safe water depth in 5 minutes, please wait to pass. Or a passing suggestion can also be given relying on meteorological information and with the help of a large model prediction.

[0056] And considering that the deeper the water depth is, the stronger the surge in the water is and the more difficult the water surface is to recover calm, therefore, referring to Figure 3 and Figure 4 , the top of the outer circle and the inner circle of the vortex partition plate 4 is arranged in a flat manner, and the height of the vortex partition plate 4 in the vertical direction presents a decreasing trend along the spiral direction from the inner circle to the outer circle. The decreasing trend can be continuous or discontinuous. In the embodiment of the present application, the decreasing trend is continuous, that is, the bottom end of the vortex partition plate 4 presents a smooth spiral downward extending curve.

[0057] In this way, as the water level in the monitored area gradually increases, the travel of the water through the vortex channel 22 into the inner ring and into contact with the liquid level sensor 5 gradually increases; that is, the deeper the water, the greater the surge of the water surface, the greater the kinetic energy consumed by the surge passing through the vortex channel 22, and the more stable the water flow when it reaches the inner ring, thereby ensuring that the influence of the surge of the water on the monitoring accuracy of the liquid level sensor 5 in the inner ring is reduced at different water depths.

[0058] In addition, the spiral-shaped vortex baffle can cause the water to rotate when flowing in the vortex channel 22, increasing the turbulence of the water flow and facilitating the precipitation and separation of suspended matter in the vortex channel 22, so that the suspended matter in the vortex channel 22 can be discharged in the area below the vortex baffle 4 that does not extend to, thereby ensuring the cleanliness of the vortex channel 22 as much as possible and reducing the probability of impurities adhering to the liquid level sensor 5 and affecting the detection accuracy.

[0059] In addition, considering the practicability and cost, the overall length of the vortex baffle 4 in the embodiment is 70-80 cm, which can meet the high-precision detection of the water depth in most cases, considering the practicability and cost, the overall length of the vortex baffle 4 in the embodiment is 70-80 cm, which can meet the high-precision detection of the water depth in most cases.

[0060] At the same time, in order to further enhance the wave suppression effect of the vortex baffle 4, with reference to Figure 3 and Figure 5 In other feasible embodiments, a wave suppression plate 41 can be installed on the inner arc side and / or the outer arc side of the vortex baffle 4 along the height direction thereof, specifically, the wave suppression plate 41 is flexibly mounted on the vortex baffle 4, the wave suppression plate 41 is detachably mounted on the vortex baffle 4, and the width of the wave suppression plate 41 along the radial direction of the monitoring cylinder 2 is less than the width of the vortex channel 22. Specifically, a plurality of sockets along the axial direction of the monitoring cylinder 2 are fixedly connected to the inner arc side of the vortex baffle 4, and a plurality of plug pieces are fixedly connected to the wave suppression plate 41 and plugged into the sockets, and the wave suppression plate 41 and the plug pieces are flexibly connected by rubber.

[0061] In this way, the plurality of wave suppression plates 41 flexibly mounted on the vortex baffle 4 can further weaken the energy of the surge of the water flowing in the vortex channel 22, and will not have a great impact on the rotational flow of the water in the vortex channel 22.

[0062] In addition, it is also considered that there may still be suspended matter on the surface of the water, and the suspended matter rises with the rising of the water depth, for this, with reference to Figure 2 and Figure 3A plurality of water inlets 21 are arranged on the bottom end of the monitoring cylinder 2, and the water inlets 21 are arranged along the axial direction of the monitoring cylinder 2 but are not higher than the overall height of the vortex partition plate 4. The filter screen 3 is arranged in a cylindrical shape around the outer periphery of the monitoring cylinder 2, and a floating ring 7 is arranged around the outer periphery of the filter screen 3. The floating ring 7 rises with the rising of the water level, and the upper end surface of the floating ring 7 is fixedly connected with a ring-shaped slag baffle 71. The floating ring 7 can be made of foam or an air bag and has a large buoyancy in water. The inner peripheral wall of the floating ring 7 is fixedly connected with brush hairs 72 arranged in a ring shape around the outer periphery of the filter screen 3, and the bottom of the floating ring 7 is fixedly connected with a bracket 73.

[0063] Therefore, even if the water depth rises, the floating ring 7 can always rise with the water level, and the slag baffle 71 arranged thereon can reduce the probability of suspended matter in the water passing through the filter screen 3 to a certain extent. When the water surge of the waterlogging water monitoring station of the application is impacted, 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 water surge. In this case, the brush hairs 72 on the inner side of the floating ring 7 can have a certain impact buffering effect and can 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 maintain a good cleaning degree after the water recedes. The bracket 73 is arranged to avoid the floating ring 7 and the brush from being in contact with the ground during the non-waterlogging period, thereby prolonging the service life as much as possible.

[0064] The implementation principle of the waterlogging water monitoring station of the application is as follows:

[0065] The main body of the waterlogging water monitoring station of the application is arranged on the raised base 1, so that the waterlogging water monitoring station does not work in the initial stage of waterlogging. The probability of the filter screen 3 being blocked by impurities such as dirt and dust mixed in the water in the initial stage of waterlogging can be effectively avoided, and the probability of these impurities adhering to the liquid level sensor 5 with the water can also be avoided, thereby ensuring the service life of the liquid level sensor 5 as much as possible and reducing the maintenance frequency.

[0066] When the depth of the accumulated water in the monitored area rises, the accumulated water will flood 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, this can filter out impurities in the accumulated water entering the monitoring tube 2; on the other hand, the upper layer of the accumulated water is mostly clear liquid, which can also reduce the impact on the service life of the liquid level sensor 5 during the contact monitoring process 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 before it can spread to the liquid level sensor 5. Even if the accumulated water in the monitored area generates a large surge, the kinetic energy of the surge 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 on the inner circle of the vortex baffle 4, so that the liquid level sensor 5 can accurately and real-timely measure the depth of the 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 or water surges.
