Description

Technical Field

[0001] This invention relates to the fields of flood discharge safety and smart water conservancy, and in particular to an online monitoring device for flood discharge atomization and heavy rainfall and its usage method. Background Technology

[0002] With the adjustment of the national power energy structure, a surge in hydropower development has swept across southwestern China, leading to the construction of an increasing number of high dams. To address the energy dissipation problem during high dam flood discharge, a number of new energy dissipation methods have emerged and been widely applied, such as combined wide-tail pier energy dissipation, narrow-slit cantilever energy dissipation, and differential cantilever energy dissipation. While these methods achieve relatively good energy dissipation effects, they can cause severe flood discharge atomization problems. During operation, flood discharge atomization can adversely affect the safe operation of the dam, the surrounding environment, and the stability of the slopes and energy dissipation zone protection structures on both banks. Among these, atomized rainfall during flood discharge is a natural phenomenon resulting from flood discharge atomization in high dams, characterized by high intensity, strong regionality, and rapid velocity decay. Atomized rainfall can be defined as extremely heavy rainfall based on its intensity, with rainfall reaching 6000–10000 mm / h, which is 50–80 times the intensity of natural rainstorms; in the core atomization zone, the wind speed of the water jet can reach 30 m / s. Therefore, it is necessary to conduct online monitoring of the atomized rainfall during flood discharge to provide real-time assessment and early warning of the safety of high dam flood discharge.

[0003] In existing technologies, traditional rainfall monitoring devices typically consist of a tipping bucket rain gauge, a data acquisition module, and a transmission module. They usually only consider conventional rainfall monitoring and acquisition. They do not adequately consider the special needs of flood discharge atomization under extremely heavy rainfall conditions. Under heavy rainfall conditions, the traditional rain gauge tipping bucket and drainage system almost fail due to the rainfall greatly exceeding the maximum range of the traditional rain gauge, making it impossible to accurately measure the rainfall. This affects the accuracy and timeliness of flood discharge atomization rainfall early warning information.

[0004] To address this, an online monitoring device for super-heavy rainfall atomization during flood discharge and its usage method are proposed. Summary of the Invention

[0020] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0021] Reference Figures 1-5 This invention provides an online monitoring device for flood discharge atomization-based heavy rainfall, comprising: Rain-collecting cylinder 1 has a diameter of 200mm and is located at the top of the box. The bottom of the rain-collecting cylinder 1 is equipped with a drainage control component and a liquid level detection component; A liquid level detection component is installed at the bottom of the rain-collecting cylinder 1 to measure the water level changes inside the rain-collecting cylinder 1 in real time. The drainage control component is installed at the bottom of the rain collection cylinder 1 to control and monitor the water level of the rain collection cylinder 1. When the water level of the rain collection cylinder 1 reaches the set value, drainage is automatically started. When the water in the rain collection cylinder 1 is drained, the drainage valve is automatically closed and the rain collection cylinder 1 starts collecting rainwater again. When the water level of the rain collection cylinder 1 reaches the set water level value again, drainage is automatically started again, and the cycle is linked. The data acquisition and transmission component is installed on the housing and connected to the liquid level detection component, the drainage control component, and the terminal device 9. The terminal device 9 is used to acquire, automatically record, and locally store measurement data in real time. The measurement data is wirelessly transmitted to the cloud platform. The cloud platform statistically analyzes the change law of the water level of the rain-collecting cylinder 1 over time and analyzes and outputs the rainfall per unit time, i.e., the fog and rain intensity, in real time based on the water level change and the opening and closing time of the drainage valve. With this configuration, the present invention uses a housing to fix the device at the monitoring point, and mounts the rain-collecting cylinder 1 and the data acquisition and transmission component on the housing. The housing improves the overall structural strength of the device, enabling it to withstand the impact of extremely heavy rainfall. The liquid level detection component can monitor the liquid level in the rain-collecting cylinder 1 in real time, and the data acquisition and transmission component collects and stores the liquid level data obtained by the liquid level detection component. The drainage control component automatically and quickly drains the water, and collects a large amount of rainfall in real time. At the same time, the data acquisition and transmission component transmits the liquid level data to the terminal device 9 for real-time assessment and early warning of the safety of high dam flood discharge. This invention can collect and transmit rainfall data under conditions of flood discharge and atomization during extremely heavy rainfall. When the water level in the rain-collecting cylinder 1 is higher than a preset threshold, it can automatically open the drainage control component to discharge rainwater. It has a high degree of automation, avoids the need for manual intervention, reduces maintenance costs and safety hazards, can adapt to monitoring and collecting different amounts of rainfall, and improves work efficiency.

[0022] The scheme is further optimized. The data acquisition and transmission components include a power distribution box 4 installed on the enclosure. The power distribution box 4 contains a wireless transmission module 11, a data acquisition terminal 14, and an LCD display controller 7.

The LCD controller 7 is used to control the upper and lower limits of the liquid level when the drainage control component is turned on and off, and to display the data acquired by the data acquisition terminal; the LCD controller 7 is electrically connected to the data acquisition terminal. If the liquid level in the rain-collecting cylinder 1 is higher than the upper limit, the LCD controller 7 controls the drainage control component to open; if the liquid level in the rain-collecting cylinder 1 is lower than the lower limit, it controls the drainage control component to close. The LCD controller 7 can also display data acquired by the data acquisition terminal, such as the current liquid level height and the current opening and closing status of the drainage control component, and can also customize the display of required parameter results. The LCD controller 7 is electrically connected to the data acquisition terminal.

[0023] The design is further optimized by adopting a hollow cylindrical structure for the rain-collecting cylinder 1, which is welded to the center of the top of the box. The bottom of the rain-collecting cylinder 1 is provided with a first opening and a second opening. The first opening is used to install the drainage control component, and the second opening is used to install the liquid level detection component. The diameter of the first opening is larger than that of the second opening. The drainage control assembly includes a drainage pipe 3 installed on the housing, the top of the drainage pipe 3 being fixedly connected to and communicating with the first opening at the bottom of the rain-collecting cylinder 1; a solenoid valve 2 is installed on the drainage pipe 3, and the solenoid valve 2 is electrically connected to the data acquisition terminal 14 through a communication circuit; the data acquisition terminal 14 is used to control the opening and closing state of the solenoid valve 2; a sand discharge facility 20 is provided at the bottom of the rain-collecting cylinder 1, and the solenoid valve 2 is connected to a solenoid valve control facility 15; The specific model and size of solenoid valve 2 can be set according to the specific application environment. For example, it can be a normally closed solenoid valve with a specification size of DN50, a working voltage of 12V DC, and a material of 304 stainless steel. In this embodiment, no specific limitation is made. When the liquid level reaches the preset threshold, the data acquisition terminal 14 sends an opening command to the solenoid valve 2 through the communication circuit, the solenoid valve 2 opens, and the rainwater is discharged through the drain pipe 3; when the liquid level drops to a safe range, the data acquisition terminal 14 sends a closing command, and the solenoid valve 2 closes.

[0024] The scheme has been further optimized. The power distribution box 4 is equipped with a power supply system 15. The data acquisition terminal 14, the wireless transmission module 11, and the liquid level detection component are all electrically connected to the power supply system 15 through power lines.

[0025] The scheme is further optimized. The liquid level detection component includes a connecting pipe 5, a liquid level detection sensor 10, and a sand and gravel clogging prevention valve. The liquid level detection sensor 10 is installed at the bottom of the rain-collecting cylinder 1, and the connecting pipe 5, the liquid level detection sensor 10, and the sand and gravel clogging prevention valve are connected in sequence from bottom to top. The detection end of the liquid level sensor 10 is fixed inside the connecting pipe 5 and is used to collect the current liquid level height of the rain-collecting cylinder 1; the liquid surface of the connecting pipe 5 is connected to the liquid surface of the connecting pipe 5. The data collected by the liquid level detection sensor 10 is electrically connected to the data acquisition terminal 14, and the liquid level detection sensor 10 is electrically connected to the power supply system 15 through a power cord; An aluminum alloy plate is installed inside the box. The drain pipe 3 and the connecting pipe 5 are located on one side of the aluminum alloy plate, and the distribution box 4 is located on the other side of the aluminum alloy plate. The communication circuit runs through the aluminum alloy plate, and a waterproof structure is provided between the communication circuit and the aluminum alloy plate.

[0026] The anti-sand and gravel blockage valve is manually operated. During the use of the monitoring and early warning device, the anti-sand and gravel blockage valve is always closed. Before using the monitoring and early warning device, it is necessary to manually observe whether there are impurities such as mud and sand in the connecting pipe 5, and manually control the anti-sand and gravel blockage valve to discharge the impurities such as mud and sand in the liquid level detection component pipe. With this setup, the liquid level detection sensor 10 collects real-time liquid level data in the rain-collecting cylinder 1 and transmits the detected liquid level data to the data acquisition terminal 14 via a communication circuit. The data acquisition terminal 14 collects and stores the liquid level data acquired by the liquid level detection sensor 10, and simultaneously transmits the liquid level data to the terminal device 9 via the wireless transmission module 11, thereby achieving remote monitoring and data transmission.

[0027] Further optimization of the scheme: the box body includes a box frame 6, and aluminum alloy plates 8 are installed on the outer walls of the box frame 6; the box frame 6 is used to fix it on the cement floor 12 of the monitoring point; in this embodiment, the box frame 6 is a cuboid structure, which can ensure that the overall strength of the device can resist the damage of heavy rainfall and strong winds during monitoring; the inlet of the drain pipe 3 is connected to the bottom outlet of the rain-collecting cylinder 1, and the outlet of the drain pipe 3 extends from the aluminum alloy plate 8 located on the side wall of the box body; The rain-collecting cylinder 1 is welded to the aluminum alloy plate 8 located at the top. The drain pipe 3 and connecting pipe 5 are installed on the box frame 6, and the distribution box 4 is installed on the aluminum alloy plate 8. Handles are installed on both sides of the box frame 6, and an openable aluminum alloy door 18 is installed on one side of the box frame 6 and one side of the distribution box 4. The aluminum alloy plate 8 is used to separate the distribution box 4 from the power supply system to prevent the discharged rainwater and mud from affecting the normal operation of the monitoring and early warning device. Waterproof facilities 19 are installed on the aluminum alloy door 18, and raised aluminum alloy strips 21 are provided on the four sides of the outer side of the distribution box 4; the lower ends of the drainage control component and the liquid level detection component are kept in a leaky state to ensure that the drainage control component drains water and the liquid level detection component removes sand; the drainage control component and the liquid level detection component are electrically connected to the data acquisition terminal using a communication circuit; the communication circuit passes through the aluminum alloy plate used for separation inside the box, and waterproof measures are taken in the part that passes through the aluminum alloy plate to prevent water from entering the distribution box 4; The aluminum alloy door 18 adopts a concave design and is equipped with waterproof strips on all four sides. When the aluminum alloy door 18 is closed, the aluminum alloy strips 21 protruding on the four sides of the outer side of the distribution box 4 are perfectly connected with the waterproof strips on the four sides of the inner side of the aluminum alloy door 18, ensuring that each component in the distribution box 4 is in a water-free state when it is working.

[0028] The scheme was further optimized by installing several overhead supports 17 at the bottom of the box frame 6. The overhead supports 17 were fixed to the cement floor 12 of the monitoring point by expansion bolts.

[0029] The design was further optimized, and the height of the rain-collecting cylinder 1 was set at 400mm.

[0030] Further optimization of the scheme: the data acquisition terminal 14 meets the functions of automatic saving, real-time clock, and data communication. The data acquisition terminal 14 can work independently. The clock and memory must be powered by 50V AC or 12V DC. Of course, those skilled in the art can choose a data acquisition terminal model that meets the requirements according to the actual situation. This is only an example and is not specifically limited.

[0031] To further optimize the solution, the power supply system 15 uses a 50Ah, 12V battery; of course, those skilled in the art can select a suitable battery according to actual needs, this is only an example and not a specific limitation.

[0032] Further optimization of the solution requires that the wireless transmission module 11 support high-speed 4G access from China Mobile, China Unicom, and China Telecom, as well as 3G and 2G access from China Mobile and China Unicom. It should also support protocol pass-through mode, custom registration packets and heartbeat packets, support two-way socket connections, support TCP Server, and support pass-through cloud access. It should feature high speed and low latency, and support FTP self-upgrade protocol and FOTA self-upgrade protocol. Of course, those skilled in the art can select a suitable wireless transmission module based on actual needs; this is merely an example and not a specific limitation.

[0033] The scheme was further optimized so that the liquid level detection sensor 10 has a range of 0mm to 1000mm, a resolution of 0.1mm, an accuracy of ±0.5% (0 to +50℃), and is powered by 12V DC.

Step 3: Based on the intensity of the atomized rain during the on-site flood discharge, set the upper and lower limits of the liquid level in the rain-collecting cylinder 1; Step 4: Activate the automatic monitoring mode and start collecting atomized rain through the rain collection cylinder 1. The liquid level detection component automatically obtains the current liquid level height in the rain collection cylinder 1 and transmits it to the data acquisition and transmission component. Step 5: The data acquisition and transmission component compares the current liquid level with the upper and lower limits of the rain collection cylinder 1. If it is higher than the upper limit of the rain collection cylinder 1, the drainage control component is activated to quickly drain the rainwater from the rain collection cylinder 1.
