Description
Technical Field
[0001] The present invention relates to the technical field of road drainage flow monitoring, and particularly relates to a rainwater flow monitoring device at the inlet of a sponge facility and a using method thereof. Background Art
[0002] A sponge city starts from "source emission reduction, process control, and systematic governance" through urban planning and construction management, and comprehensively adopts technical measures such as "infiltration, retention, storage, purification, utilization, and drainage" - sponge facilities. It coordinates the relationships between water quantity and quality, ecology and safety, distribution and concentration, green and gray, landscape and function, onshore and offshore, aboveground and underground, etc., effectively controls urban rainfall runoff, and minimizes the damage caused by urban development and construction activities to the original natural hydrological characteristics and water ecological environment. The city can be like a "sponge", having good "elasticity" in adapting to environmental changes and resisting natural disasters, realizing the urban development mode of natural accumulation, natural infiltration, and natural purification, which is conducive to achieving multiple goals of restoring the urban water ecosystem, conserving urban water resources, improving the urban water environment, ensuring urban water safety, and reviving urban water culture.
[0003] As the core concept of new urbanization, the construction of a sponge city has played an important role in preventing urban waterlogging and improving the urban water environment, and is about to enter the stage of systematic full-region promotion. In order to quantitatively evaluate the construction effect of a sponge city, a series of monitoring and evaluation work has been carried out in national and some provincial pilot cities. The evaluation content covers the full-process evaluation of sponge city planning, construction, system, and its effect, emphasizing the combination of quantitative and qualitative methods, especially the quantitative evaluation of the construction situation and effect.
[0004] The online flow monitoring of a sponge city includes the flow monitoring of sponge facilities, sponge projects, the drainage pipelines of sponge construction areas, and the in-river outlets. Such monitoring data is of great significance for evaluating the construction effectiveness of sponges and analyzing the rainwater runoff characteristics of this area. And the monitoring of the inlet flow of sponge facilities plays an important role in the monitoring of a sponge city.
[0005] Bioretention facilities, sunken green spaces and other sponge facilities in sites such as roads and building communities are normally surrounded by curbstones on all sides, and openings or holes are made on the curbstones at appropriate positions to collect rainwater in the surrounding catchment areas. When setting up monitoring equipment, it is implemented by means of the open curbstones. In recent years, in order to increase the surface runoff speed, the catchment surfaces on one side or multiple sides of more and more sponge facilities are made into scattered drainage treatments. Here, the scattered drainage treatment means directly discharging from the sidewalk to the sponge facilities beside the sidewalk. The treatment method at the inlet of such sponge facilities creates difficulties for the monitoring of the rainwater flow at the inlet of the sponge facilities.
[0006] Currently, common methods include constructing open channels or trenches in advance to install flow monitoring devices, or adjusting the slope of the catchment area; however, these methods have problems such as large measurement errors, poor sensory effects, and being easily affected by the environment.
[0007] Currently used monitoring devices such as radar flow meters and Doppler flow meters are difficult to accurately monitor low water levels and rapidly changing water flow conditions due to factors such as water flow state, sand, gravel, and soil, resulting in relatively large measurement errors.

Detailed implementation manners
[0042] To better understand the above technical solutions, the exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although the exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments described herein. On the contrary, these embodiments are provided to enable a clearer and more thorough understanding of the present invention and to fully convey the scope of the present invention to those skilled in the art.
[0043] Embodiment 1
[0044] As Figure 1 shown, a rainwater flow monitoring device for the inlet of a sponge facility in this embodiment includes a triangular weir 1, a weir type flowmeter 2, and two groups of flow guiding components 3.
[0045] Specifically, the triangular weir 1 is installed inside the sponge facility a. The direction of the inlet end of the triangular weir 1 faces the sidewalk 4, and the direction of the outlet end of the triangular weir 1 faces away from the sidewalk 4. A positioning groove 11 is provided on the inner wall of the bottom of the triangular weir 1 for positioning the weir type flowmeter 2. The weir type flowmeter 2 is vertically installed in the positioning groove 11 for monitoring the flow rate of the rainwater entering the triangular weir 1. By adopting the combination of the triangular weir 1 and the weir type flowmeter 2, a stable water level will be formed when the water flow enters the triangular weir 1, and the weir type flowmeter 2 can monitor the water level of the rainwater in real time. Thus, the rainwater flow rate entering the sponge facility can be accurately measured through the weir type flowmeter 2, especially for the rainwater flow rate with low water level and unstable water flow state, and the rainwater flow rate can still be accurately measured. The two groups of diversion components 3 are both arranged along the curb 5 of the sidewalk 4, and the two groups of diversion components 3 are both fixedly connected to the outer wall of the curb 5. By arranging the two groups of diversion components 3, they can effectively concentrate the rainwater scattered and flowing into the sponge facility a on the sidewalk 4 and guide it into the triangular weir 1 for monitoring, solving the problem that it is difficult to monitor the influent flow rate of the sponge facility with scattered drainage treatment. Moreover, by fixedly connecting the two groups of diversion components 3 to the outer wall of the curb 5, they can stably fix the two groups of diversion components 3 and prevent the two groups of diversion components 3 from falling off due to the scouring of the rainwater, thus affecting the monitoring accuracy of the weir type flowmeter 2. The relative ends of the two groups of diversion components 3 are flush with the inner walls on both sides of the inlet end of the triangular weir 1, and the side walls of the relative ends of the two groups of diversion components 3 are in contact with the triangular weir 1, which can prevent the rainwater entering the diversion components 3 from flowing out through the gap between the diversion components 3 and the triangular weir 1, thus affecting the monitoring accuracy of the weir type flowmeter 2. The diversion component 3 can guide the rainwater scattered and entering the sponge facility a from the sidewalk 4 to the outlet of the diversion component 3 and the inlet of the triangular weir 1 in sequence and enter the interior of the triangular weir 1, so that the weir type flowmeter 2 can monitor the rainwater flow rate entering the sponge facility a.
[0046] Further, as Figure 3 and Figure 4As shown in the figure, this embodiment further includes a pulling component 6 and a guiding component 7. The triangular weir 1 includes a weir trough 12 and two telescopic weir plates 13. The vertical cross-section of the weir trough 12 is concave-shaped. The inlet and outlet ends of the weir trough 12 are respectively the inlet and outlet ends of the triangular weir 1. Vertical installation grooves 121 are provided on the inner walls on both sides of the outlet end of the weir trough 12. The opposite ends of the two telescopic weir plates 13 are correspondingly connected. The opposite ends of the two telescopic weir plates 13 are respectively located in the two installation grooves 121. The bottoms of the two telescopic weir plates 13 are connected to the bottom wall of the weir trough 12. An installation space 122 is provided inside the weir trough 12. The pulling component 6 is installed in the installation space 122. The guiding component 7 is respectively installed at the top of the two installation grooves 121 and inside the installation space 122. The output end of the pulling component 6 passes through the installation space 122 through the guiding component 7 and is respectively connected to the tops of the two telescopic weir plates 13. The pulling component 6 can simultaneously drive the two telescopic weir plates 13 to synchronously expand and contract along an arc-shaped trajectory towards or away from the center of the outlet end of the weir trough 12, so as to change the size of the outlet end of the triangular weir 1. By providing the two telescopic weir plates 13, the pulling component 6 and the guiding component 7, the sponge facility inlet rainwater flow monitoring device can change the size of the outlet end of the triangular weir 1 according to the actual rainwater flow and rainfall, ensuring accurate measurement under different rainfall conditions, improving adaptability and practicability, reducing measurement errors caused by unstable water flow states or external factors such as gravel and mud, and further improving the accuracy of flow monitoring. Preferably, the positioning groove 11 is located at the center of the bottom inner wall of the weir trough 12, which can make the measurement point of the weir-type flowmeter 2 in the place where the water flow is the most uniform and stable, thus improving the accuracy and reliability of flow monitoring.
[0047] Furthermore, as Figure 3 , Figure 4 and Figure 5As shown in the figure, the pulling assembly 6 includes a reduction motor 61, a first wire spool 62, a second wire spool 63, a first steel wire 64, and a second steel wire 65. The reduction motor 61 is installed on the bottom wall of the installation space 122. The output end of the reduction motor 61 is sequentially connected to the first wire spool 62 and the second wire spool 63, and the reduction motor 61 can drive the first wire spool 62 and the second wire spool 63 to rotate synchronously. One end of the first steel wire 64 is connected to the second wire spool 63, and the other end is connected to the top of a telescopic weir plate 13 through a guiding assembly 7. One end of the second steel wire 65 is connected to the first wire spool 62, and the other end is connected to the top of the other telescopic weir plate 13 through a guiding assembly 7. The reduction motor 61 can drive the first wire spool 62 and the second wire spool 63 to rotate synchronously, so that the first steel wire 64 and the second steel wire 65 are respectively wound or released on the second wire spool 63 and the first wire spool 62, so as to drive the telescopic weir plate 13 to expand and contract along an arc trajectory toward or away from the center of the outlet end of the weir trough 12. By providing the reduction motor 61, the first wire spool 62, the second wire spool 63, the first steel wire 64, and the second steel wire 65, the reduction motor 61 can drive the first wire spool 62 and the second wire spool 63 to rotate synchronously, so that the first steel wire 64 and the second steel wire 65 can be wound or released smoothly and synchronously, ensuring that the two telescopic weir plates 13 can be adjusted simultaneously and evenly in angle, thereby realizing the adjustment of the size of the outlet end of the triangular weir 1, enabling the rainwater in the triangular weir 1 to flow out stably from the outlet end, and making the weir type flowmeter 2 more accurate when monitoring the rainwater flow rate.
[0048] Furthermore, as Figure 3 and Figure 4 shown in the figure, the guiding assembly 7 includes a plurality of fixed pulleys 71. At least two fixed pulleys 71 are respectively installed on the top walls of the two installation grooves 121, and the other plurality of fixed pulleys 71 are arranged at intervals on the top wall and the side wall of the installation space 122. The first steel wire 64 and the second steel wire 65 are respectively attached to the outer walls of the plurality of fixed pulleys 71 to guide and deflect the first steel wire 64 and the second steel wire 65, which can ensure that the first steel wire 64 and the second steel wire 65 can run smoothly along a predetermined path, realizing not only the precise guiding of the steel wire but also effectively changing the direction change of the steel wire, making the adjustment of the telescopic weir plate 13 more accurate and stable. Moreover, through the cooperation of the first steel wire 64 and the second steel wire 65 with the fixed pulley 71, the friction force of the first steel wire 64 and the second steel wire 65 pulling the telescopic weir plate 13 can be reduced, reducing the risk of wear caused by friction, helping to protect the steel wire rope, preventing it from breaking or being damaged during frequent pulling, and thus extending the service life of the entire pulling system. And, the plurality of fixed pulleys 71 can ensure that the first steel wire 64 and the second steel wire 65 can maintain the correct tension and running trajectory under operating conditions, avoiding possible deviation or winding problems of the first steel wire 64 and the second steel wire 65, and improving the stability and reliability of the system.
[0049] Furthermore, as Figure 3 , Figure 4 and Figure 6 shown, the telescopic weir plate 13 includes a first sub-plate 131 and a second sub-plate 132. The bottom of the first sub-plate 131 is connected to the bottom wall of the weir trough 12, providing a stable foundation support. A telescopic space 1311 is provided at the top of the first sub-plate 131, and the second sub-plate 132 is placed within the telescopic space 1311. One end of the second sub-plate 132 away from the installation groove 121 is hinged to the first sub-plate 131, and one end of the second sub-plate 132 close to the installation groove 121 is slidably connected to the first sub-plate 131 through a guide block 1321 and a guide groove 1312. The connection between the second sub-plate 132 and the first sub-plate 131 by means of a hinge not only ensures the firmness of the structure but also allows an appropriate range of motion. The second sub-plate 132 can be slidably connected to the first sub-plate 131 within the telescopic space 1311 through the guide block 1321 and the guide groove 1312, enabling the telescopic weir plate 13 to flexibly adjust the angle between it and the horizontal plane according to actual needs, improving the stability and directionality during the sliding of the second sub-plate 132, preventing deviation or jamming, and at the same time enhancing the adaptability to different water flow conditions to ensure effective flow control and measurement under various rainfall intensities. The first wire 64 and the second wire 65 are respectively connected to the tops of the two second sub-plates 132 facing the installation groove 121 to drive the second sub-plate 132 to rotate around the axis of the hinge between the second sub-plate 132 and the first sub-plate 131, thereby adjusting the size of the outlet end of the triangular weir 1, so as to more finely control the water flow velocity and water level height, greatly improving the accuracy and reliability of flow monitoring. Generally, the angle between the two second sub-plates 132 is generally between 20° and 100°, and the specific angle depends on the water level of the rainwater.
[0050] Furthermore, as Figure 6 shown, one end of the first sub-plate 131 and the second sub-plate 132 facing the installation groove 121 are both arc-shaped structures, which can make the second sub-plate 132 slide more smoothly within the telescopic space 1311 of the second sub-plate 132. Since the hinge between the first sub-plate 131 and the second sub-plate 132 is located at the front end and the rotation trajectory is arc-shaped, setting one end of the first sub-plate 131 and the second sub-plate 132 facing the installation groove 121 as arc-shaped structures can avoid interference between the second sub-plate 132 and the first sub-plate 131 during the rotation of the second sub-plate 132, thus improving the smoothness of the sliding of the second sub-plate 132.
[0051] Preferably, the outlet end of the weir trough 12, that is, the installation groove 121, can be opened, as Figure 4As shown, it facilitates the installation of the reduction motor 61, the first spool 62, the second spool 63, the first steel wire 64, the second steel wire 65 and multiple fixed pulleys 71, as well as the connection of the first steel wire 64 and the second steel wire 65 to the two second sub-boards 132 respectively. Moreover, it can also facilitate the subsequent maintenance of the device. It should be noted that at the installation groove 121, it can be detachably connected by means such as snap connection and bonding, which are all prior arts and will not be elaborated here. And, waterproof materials are applied at the connection of the installation groove 121 to prevent rainwater or impurities from entering the installation space 122 and reduce the damage rate of the device.
[0052] Furthermore, as Figure 1 shown, it further includes a fixing bracket 8 and a fixing member 9. The fixing bracket 8 is in a U-shape vertically arranged. The two ends of the fixing bracket 8 are respectively connected to the top of the triangular weir 1. The top of the weir type flowmeter 2 is connected to the fixing member 9 through the fixing bracket 8. By setting the fixing bracket 8 and the fixing member 9, it can fix the weir type flowmeter 2 and make the installation of the weir type flowmeter 2 more stable. Moreover, by setting the fixing bracket 8 as a U-shape vertically arranged, with the two ends respectively connected to the top of the triangular weir 1 and the top respectively connected to the weir type flowmeter 2 and the fixing member 9, it can also prevent the equipment from being stolen and improve the safety.
[0053] Furthermore, as Figure 1 shown, the diversion assembly 3 includes multiple diversion grooves 31. The multiple diversion grooves 31 are connected end to end through a snap mechanism 10. It can flexibly adjust the quantity and length of the diversion grooves 31 according to actual needs, and make the connection between the diversion grooves 31 simple and fast. The side wall of each diversion groove 31 is fixedly connected to the outer wall of the curb 5. The multiple diversion grooves 31 communicate with each other. The multiple diversion grooves 31 are all inclined towards the direction of the triangular weir 1 to guide the rainwater to converge towards the triangular weir 1. It can effectively guide the rainwater scattered from the sidewalk 4 into the triangular weir 1 for centralized measurement, ensure that the rainwater can smoothly flow into the triangular weir 1, improve the rainwater collection efficiency, and at the same time reduce the measurement error caused by the dispersion of rainwater.
[0054] Furthermore, as Figure 7 、 Figure 8 and Figure 9As shown, the buckle mechanism 10 is vertically arranged and includes a pull ring 101, a connecting rod 102, a sleeve 103, a clamping member 104, and an elastic member 105. A sliding groove 313 is provided on the side wall at one end of the diversion groove 31, and a clamping space 314 is provided inside the bottom at one end of the diversion groove 31. The sleeve 103, the clamping member 104, and the elastic member 105 are all located inside the clamping space 314. The top of the sleeve 103 is connected to the top of the clamping space 314. The clamping member 104 is placed inside the sleeve 103. The top of the clamping member 104 is connected to the bottom of the connecting rod 102. The top of the connecting rod 102 passes through the bottom top wall of the clamping space 314 and the diversion groove 31 to be connected to the pull ring 101. The elastic member 105 is sleeved outside the clamping member 104 and is used to provide a buffering force and a resilience force to the clamping member 104. One end of the clamping member 104 away from the sliding groove 313 is a clamping end, which is hemispherical and faces downward. A connecting block 311 is provided on the side wall at the other end of the diversion groove 31. A plurality of rotatable rollers 312 are provided at the bottom of the connecting block 311. When two adjacent diversion grooves 31 are clamped in cooperation, when the rollers 312 enter the sliding groove 313 along with the connecting block 311, the connecting block 311 travels more smoothly in the sliding groove 313, avoiding the phenomenon of jamming. A clamping groove 3111 is provided at the top of the connecting block 311. The diversion groove 31 can be inserted into the sliding groove 313 of an adjacent diversion groove 31 through the connecting block 311 and a plurality of rollers 312, and the two adjacent diversion grooves 31 are clamped through the cooperation of the clamping member 104 and the clamping groove 3111. By providing the sleeve 103, it can play a guiding role for the clamping member 104 to prevent the clamping member 104 from deviating from the track, so as to avoid the clamping member 104 being unable to be clamped with the clamping groove 3111. By providing the pull ring 101, the connecting rod 102, and the elastic member 105, the connection and disassembly between the diversion grooves 31 become simple and fast. The operator only needs to pull the pull ring 101 to easily complete the clamping and detachment of the clamping member 104 and the clamping groove 3111 on the connecting block 311, improving the disassembly and assembly efficiency. Moreover, during later operation and maintenance, only the pull rings 101 on two adjacent diversion grooves 31 need to be pulled simultaneously to drive the connecting rod 102 to drive the clamping member 104 to rise vertically. At this time, the elastic member 105 is compressed and provides a buffering force to the clamping member 104, so that the clamping ends of the two clamping members 104 are detached from the two clamping grooves 3111, and the diversion groove 31 to be disassembled is pulled. The diversion groove 31 moves away from the curb 5 in the sliding groove 313 through the connecting block 311 and the rollers 312, so as to disassemble the diversion groove 31 to be disassembled.When replacing a new guide groove 31, it is only necessary to insert the new guide groove 31 into the slide groove 313 through the connecting block 311 and the roller 312. Since the clamping end of the clamping piece 104 is hemispherical, when the connecting block 311 enters the slide groove 313 and touches the clamping end, the clamping piece 104 rises vertically due to the hemispherical shape of the clamping end, and the elastic piece 105 is compressed. When the clamping end of the clamping piece 104 is about to be placed in the clamping groove 3111, the elastic piece 105 instantly provides a rebound force for the clamping piece 104, so that the clamping piece 104 is placed in the clamping groove 3111, thereby completing the clamping of two adjacent guide grooves 31.
[0055] Preferably, a sealing ring may be sleeved on the outer wall of the connecting rod 102 to prevent water in the guide groove 31 from entering the clamping space 314, and the elastic member 105 may be made of rust-proof material to prevent the buckle mechanism 10 from rusting and getting stuck. At the same time, plugs are provided on both sides of the slide groove 313 to block the slide groove 313 and prevent water from entering the slide groove 313, thereby causing damage to the connecting block 311 and the roller 312.
[0056] Furthermore, a guide pattern (not shown in the figure) is provided on the inner wall of each guide groove 31, which can effectively guide rainwater to flow along a predetermined path, reduce the turbulence and energy loss of water flow in the guide groove 31, increase the water flow speed, and ensure that rainwater can flow to the triangular weir 1 more quickly and smoothly, thereby improving the overall rainwater collection and measurement efficiency.
[0057] Furthermore, the side walls of the weir trough 12 are prefabricated with precast concrete slabs, the bottom wall of the weir trough 12 is cast on-site with concrete, and ceramic tiles are laid on the outer surface of the weir trough 12, thereby reducing the internal roughness of the weir trough 12 and improving the appearance quality of the weir trough 12.
[0058] Furthermore, the present embodiment also includes a controller. The controller is fixedly installed in the installation space 122, and the controller is electrically connected to the reduction motor 61 and the weir flowmeter 2 respectively. When the weir flowmeter 2 monitors the current water level, the weir flowmeter 2 transmits the electrical signal of the water level at this time to the controller, and the controller transmits the electrical signal to the reduction motor 61, and drives the reduction motor 61 to rotate, so that the first steel wire 64 and the second steel wire 65 are synchronously wound or released on the second winding shaft 63 and the first winding shaft 62 respectively, thereby driving the second sub-plate 132 to rotate around the hinge between it and the first sub-plate 131, thereby changing the opening size of the outlet end of the triangular weir 1, so that the water flow in the weir groove 12 can be monitored more stably.
[0059] This embodiment has a simple structure and is convenient and quick to operate, improves the accuracy of monitoring the scattered rainwater of low water level, unstable water flow state, etc., reduces monitoring errors, and improves stability and adaptability.
[0060] Example Two
[0061] Different from Example One, the weir trough 12 in this example can be made of materials such as stainless steel and polymer materials, and the diversion assembly 3 can also be a component with a diversion function such as a diversion pipe.
[0062] Example Three
[0063] As Figure 1 shown, a method for using a rainwater flow monitoring device at the inlet of a sponge facility in this example includes the rainwater flow monitoring device at the inlet of the sponge facility in Example One, and further includes the following steps:
[0064] S1: When it rains, the rainwater on the sidewalk 4 enters the two groups of diversion assemblies 3 through the curb 5;
[0065] S2: The rainwater entering the two groups of diversion assemblies 3 is released from the outlet ends of the two diversion troughs 31 closest to the weir trough 12 under the guidance of the mutually connected multiple diversion troughs 31;
[0066] S3: The rainwater released in step S2 enters the weir trough 12 from the inlet end of the weir trough 12. The water level of the rainwater in the weir trough 12 continuously rises and can be released from the outlet end of the triangular weir 1 into the sponge facility a;
[0067] S31: In the case of heavy rain or rainstorm and other weather with relatively large rainfall, the rainwater entering the weir trough 12 is relatively rapid, resulting in an unstable water flow state. At this time, the weir type flowmeter 2 monitors that the water level of the rainwater rises rapidly and the water flow velocity is fast. It transmits an electrical signal of the real-time water level of the rainwater to the controller. The controller makes a judgment based on this electrical signal and transmits the judged electrical signal to the reduction motor 61, driving the output end of the reduction motor 61 to rotate, so as to drive the first winding shaft 62 and the second winding shaft 63 to rotate simultaneously, so that the first winding shaft 62 and the second winding shaft 63 respectively release the second steel wire 65 and the first steel wire 64, so that the first steel wire 64 and the second steel wire 65 synchronously drive the second sub-board 132 to rotate around the hinge joint of the second sub-board 132 and the first sub-board 131 through the guidance of multiple fixed pulleys 71, so as to reduce the angle between the second sub-board 132 and the horizontal plane, appropriately increase the outlet size of the weir trough 12, reduce the pressure when the rainwater flows out from the outlet end of the weir trough 12, make the outflow volume of the rainwater in the weir trough 12 from the outlet end larger, and make the rainwater state in the weir trough 12 more stable;
[0068] S32: When encountering weather with relatively small rainfall such as light rain, the water level of the rainwater entering the weir trough 12 is relatively low. At this time, the weir-type flowmeter 2 monitors that the water level of the rainwater rises slowly and the water flow velocity is slow. At this time, the weir-type flowmeter 2 monitors that the water level of the rainwater rises slowly and the water flow velocity is slow. It transmits the electrical signal of the water level of the rainwater at this time to the controller. The controller makes a judgment based on this electrical signal and transmits the judged electrical signal to the reduction motor 61 to drive the output end of the reduction motor 61 to rotate, so as to drive the first spool 62 and the second spool 63 to rotate simultaneously, so that the first steel wire 64 and the second steel wire 65 are respectively wound around the second spool 63 and the first spool 62, so that the first steel wire 64 and the second steel wire 65 synchronously drive the second sub-plate 132 to rotate around the hinge joint between the second sub-plate 132 and the first sub-plate 131 through the guidance of a plurality of fixed pulleys 71, so as to increase the angle between the second sub-plate 132 and the horizontal plane, appropriately reduce the outlet size of the weir trough 12, increase the pressure when the rainwater flows out from the outlet end of the weir trough 12, make the outflow volume of the rainwater in the weir trough 12 from the outlet end smaller, and make the state of the rainwater in the weir trough 12 more stable.
[0069] S4: The weir-type flowmeter 2 monitors the rainwater in a stable state entering the weir trough 12 according to step S31 or step S32, monitors the water level of the rainwater in the weir trough 12 at this time, and calculates the current rainwater flow rate based on the angle between the second sub-plate 132 and the horizontal plane.
[0070] Embodiment Four
[0071] As Figures 1-9 shown, an installation method of a rainwater flow monitoring device at the inlet of a sponge facility in this embodiment includes the rainwater flow detection device at the inlet of the sponge facility in Embodiment One, and further includes the following steps:
