[0002] The expressway precipitation collection device is a special meteorological monitoring equipment installed at the water outlet of the expressway, which is used for collecting and measuring the atmospheric precipitation along the expressway in real time.

[0003] In the prior art, the expressway precipitation collection device mainly relies on tipping bucket or weighing type measuring units. These devices have significant defects in actual application.

Although the weighing device can measure solid precipitation, the overall structure is complex, the cost is high, and the sensor is prone to zero drift and aging due to long-term bearing of the entire precipitation weight. It is inconvenient to maintain and calibrate. In addition, both types of devices need to directly contact the core measuring components with precipitation. In the environment of the expressway with dust and debris, the measurement continuity is reduced and the maintenance frequency is increased due to pollution and blockage. UTILITY MODEL CONTENT

DETAILED DESCRIPTION
[0023] With reference to the drawings of the embodiments of the present application, the technical solutions in the embodiments of the present application will be clearly and completely described, obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments of the present application, all the other embodiments obtained by the ordinary skilled in the art without creative labor are within the protection scope of the present application.
[0024] Please refer to Figures 1-4 The utility model discloses a highway flow type precipitation collection device, including water storage tank 1, the upper end of water storage tank 1 is connected with the water inlet funnel 2, and the inner bottom of water storage tank 1 is provided with a flow guide slope 101. One end of water storage tank 1 is provided with a drain pipe 3 through a connecting structure 8. The lowest point of the flow guide slope 101 points to the inlet of the drain pipe 3. An ultrasonic flow meter 4 is fixedly installed on the outside of the water storage tank 1. The measuring probe of the ultrasonic flow meter 4 is fixedly installed on the outside of the drain pipe 3. A tee pipe 5 is fixedly installed at the water outlet end of the drain pipe 3. A control valve 6 is fixedly installed at the downstream outlet end of the tee pipe 5. A collection tank 7 is arranged at the lower end of the downstream outlet end of the tee pipe 5.
[0025] The precipitation enters the water storage tank 1 through the water inlet funnel 2 and is rapidly collected to the inlet of the drain pipe 3 at the lowest point under the action of the flow guide slope 101, forming a stable water flow. When the water flow passes through the drain pipe 3, the ultrasonic flow meter 4 installed on the outer wall monitors the precipitation flowing through the pipe in real time and continuously in a non-contact manner, so as to accurately calculate the precipitation intensity and the cumulative amount. When sampling or calibrating the device is needed, the control valve 6 downstream of the tee pipe 5 can be opened to guide part of the water flow into the collection tank 7. The non-contact ultrasonic measurement fundamentally avoids the problems of blockage of sundries, deposition of silt or corrosion of the sensor caused by direct contact with rainwater, ensuring the continuity and stability of the data in the complex environment of the highway. Through the synergistic effect of the flow guide slope 101 and the drain pipe 3, the flow of liquid precipitation is guaranteed, and the solid precipitation is ensured to melt completely before entering the measurement link, realizing reliable monitoring of different forms of precipitation. Both types of precipitation monitoring are considered. At the same time, the drain pipe 3 can be quickly disassembled through the connecting structure 8. Combined with the sampling function of the tee pipe 5 and the control valve 6, the cleaning, maintenance and regular calibration of the pipeline are facilitated.
[0026] The connecting structure 8 comprises a mounting plate 801 fixedly installed on the outer side of the water storage tank 1, a sleeve 802 is arranged on the outer side of the mounting plate 801, the inlet end of the drain pipe 3 is inserted into the sleeve 802, two side plates 803 are symmetrically arranged on the outer side of the mounting plate 801, an end of each side plate 803 is fixedly connected with a cover plate 804, a sliding groove is formed in the outer side of the side plate 803, two limiting blocks 805 are slidably connected in the sliding groove, a spring 806 is fixedly installed between the two limiting blocks 805, a through hole is formed in the outer side of the cover plate 804 and communicates with the sliding groove, and a pushing block 807 is fixedly installed on the outer side of the two limiting blocks 805 and passes through the through hole;
[0027] A connecting plate 301 is fixedly installed on the outer side of the drain pipe 3, a mounting hole is formed in the outer side of the connecting plate 301 and used for inserting the side plate 803, and the end of the side plate 803 close to the cover plate 804 is located in the mounting hole;
[0028] The end of each limiting block 805 is provided with a guide inclined surface, and the side edges of the connecting plate 301 are provided with arc-shaped surfaces matched with the guide inclined surfaces;
[0029] In the locking state, the two limiting blocks 805 and the spring 806 jointly form a continuous pressure, so that the inlet end of the drain pipe 3 is tightly combined with the outlet of the water storage tank 1 through the sealing ring 9, the leakage of the connecting part is effectively prevented, and the integrity and accuracy of the flow measurement data are ensured;
[0030] The outer side of the part, in which the drain pipe 3 is inserted into the sleeve 802, is sleeved with a sealing ring 9, and the outer wall of the sealing ring 9 is in interference fit with the inner wall of the sleeve 802;
[0031] In the locking state, the two limiting blocks 805 and the spring 806 jointly form a continuous pressure, so that the inlet end of the drain pipe 3 is tightly combined with the outlet of the water storage tank 1 through the sealing ring 9, the leakage of the connecting part is effectively prevented, and the integrity and accuracy of the flow measurement data are ensured;
[0032] The upper end of the water storage tank 1 is fixedly connected with a supporting seat 10, and the water inlet funnel 2 is installed in the supporting seat 10;
[0033] Among them, the support base 10 provides a stable and standard mounting base for the water inlet funnel 2, ensuring that the funnel can always maintain accurate positioning and vertical posture during long-term outdoor use, thereby avoiding displacement or loosening caused by wind, vibration or accidental collision, and ensuring that the rainwater collection inlet is always aligned and the collection efficiency is stable.
[0034] When in use, first securely install the entire device near the highway drainage outlet, ensuring that the upper water inlet funnel 2 is accurately aligned with the rainwater collection area, and maintain its verticality and stability through the support base 10 at its bottom;
[0035] When monitoring begins, rainwater or melted snow water enters the water storage tank 1 through the inlet funnel 2. Inside the water storage tank 1, the guide slope 101 guides the water flow to converge rapidly and without stagnation to the lowest point. The water flows out from the outlet at the lowest point of the guide slope 101 and enters the drain pipe 3. At this time, the ultrasonic flow meter 4 probe installed on the outer wall of the drain pipe 3 continuously emits and receives ultrasonic signals without contacting the water flow, accurately measuring the real-time flow velocity and flow rate of the water in the pipe. The data is recorded in real time and transmitted remotely, thereby calculating the precipitation intensity and cumulative amount.
[0036] When water quality analysis or data calibration is required, the operator can manually open the control valve 6 installed at the downstream outlet of the tee pipe 5. At this time, part of the water flowing through the drain pipe 3 will be diverted at the tee pipe 5 and flow vertically downwards through the opened valve into the pre-placed collection tank 7. After the water sample collection is completed, the valve can be closed to resume the full measurement process.
[0037] When the drain pipe 3 needs cleaning due to sediment or debris accumulation, the operator first simultaneously moves the two symmetrically arranged levers 807 on the connecting structure 8 outwards. The levers 807 drive the inner fixed limiting blocks 805 to overcome the tension of the spring 806 and slide back to both sides within the groove of the side plate 803. Once the ends of the two limiting blocks 805 disengage from the outer surface of the connecting plate 301, the previously locked connecting plate 301 is released. At this time, the operator can hold the drain pipe 3 and pull it backwards to pull the connecting plate 301 out of the side plate 803. At the same time, the inlet end of the drain pipe 3 exits from the sleeve 802, and the sealing ring 9 disengages. The entire drain pipe 3 assembly (including the ultrasonic flow meter 4 probe and the tee pipe 5) is then completely disassembled for thorough cleaning or maintenance.
[0038] After cleaning, align the inlet end of the drain pipe 3 with the sleeve 802, and ensure that the mounting port on the connecting plate 301 is aligned with the two side plates 803. Push the drain pipe 3 forward smoothly. When the arc-shaped surfaces of the two sides of the connecting plate 301 contact the guide slope at the end of the limiting block 805, the arc-shaped edges of the connecting plate 301 will slide along the guide slope of the limiting block 805 under the action of the pushing force, thereby squeezing the two limiting blocks 805 inward, compressing the spring 806 between them. Continue pushing until the side plate 803 is fully inserted into the mounting port. At this time, the limiting block 805 just moves to the position of the outer plane of the connecting plate 301. The compressed spring 806 inside immediately pushes the two limiting blocks 805 to reset and pop out, completing the mechanical locking. At the same time, the inlet end of the drain pipe 3 has formed a tight interference fit with the inner wall of the sleeve 802 through the sealing ring 9 during the pushing process, ensuring the sealing of the connection. The entire disassembly and installation process does not require any tools and can be completed quickly by hand. Afterward, the device can immediately resume normal precipitation monitoring work.
