Description

Technical Field

[0001] This utility model relates to the field of monitoring water level and flow velocity of railway flood control bridges, specifically to an intelligent monitoring device for water level and flow velocity of railway flood control bridges. Background Technology

[0002] Railways are a vital component of transportation, and flood-crossing bridges are structures built to span rivers, lakes, and other bodies of water. Especially in flood-prone areas, the design and construction of flood-crossing bridges must consider various factors such as water flow, flood frequency, and intensity. The safety of flood-crossing bridges along railway lines is paramount, as damage can lead to serious accidents such as train derailments and overturning. Safety monitoring of railway flood-crossing bridges is closely related to traffic safety, transportation order, and efficiency, directly impacting the smooth flow of transportation and the safety of public life and property.

[0003] Currently, equipment used for measuring flow velocity and water level in the market has many problems. Common flow velocity and water level measurement devices often use ultrasonic velocimeters and ultrasonic level gauges to measure the flow velocity and cross-sectional area of ​​channels, but these are expensive, increasing monitoring costs and placing a heavy economic burden on large-scale railway flood control bridge monitoring. Moreover, these devices mostly only allow for fixed-point measurements, failing to comprehensively acquire water flow data at different locations on the flood control bridge, thus limiting the monitoring range. More importantly, after prolonged use, ultrasonic velocimeters are affected by environmental factors (such as impurities and air bubbles in the water) and the aging of the equipment itself, resulting in a significant decrease in measurement accuracy, making it difficult to meet the long-term, accurate monitoring needs of railway flood control bridges for water level and flow velocity. If a railway flood control bridge is damaged due to abnormal water level or flow velocity, it could potentially lead to serious accidents such as train derailment and overturning, causing not only huge economic losses but also posing a serious threat to public safety and property. Therefore, we offer an intelligent monitoring device for water level and flow velocity of railway flood control bridges. Utility Model Content

[0004] The purpose of this invention is to provide an intelligent monitoring device for water level and flow velocity of railway flood control bridges, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an intelligent monitoring device for water level and flow velocity of a railway flood control bridge, comprising a mounting shell and an angle sensor, wherein an angle adjustment component is provided on the mounting shell, and a monitoring component is provided on the angle adjustment component.

[0006] Preferably, the angle adjustment assembly includes a servo motor and an annular plate. The servo motor is mounted on the top of the mounting housing. The bottom end of the servo motor output shaft passes through the mounting housing and extends into it. A threaded rod is mounted on the bottom end of the servo motor output shaft, and a threaded block is threadedly connected to the surface of the threaded rod.

[0007] Preferably, a movable block is installed on the right side of the threaded block, and a pluggable concave plate is provided on the right side of the movable block. A rotary motor is installed at the bottom of the concave plate, and the annular plate is disposed inside the concave plate. The top end of the output shaft of the rotary motor passes through the concave plate and extends into it, and is fixedly connected to the bottom of the annular plate.

[0008] Preferably, the monitoring component includes a connecting plate, which is installed on the right side of the annular plate. The right side of the connecting plate passes through the concave plate and extends to its outside. A fixing shell is installed on the left side of the bottom of the connecting plate. A data transmission module and a controller are respectively installed on the left and right sides of the bottom of the inner wall of the fixing shell.

[0009] Preferably, a radar flow rate and water level integrated machine is installed at the bottom of the connecting plate and on the right side of the fixed shell, and a camera is installed on the right side of the bottom of the connecting plate.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0011] This invention utilizes the coordinated operation of a servo motor, annular plate, threaded rod, threaded block, moving block, concave plate, rotary motor, connecting plate, fixed shell, data transmission module, controller, integrated radar flow velocity and water level meter, and camera. The positions of the camera and integrated radar flow velocity and water level meter can be adjusted as needed, allowing for clear capture of water flow details under different flow conditions. For example, during floods, special flow patterns such as oblique flows and whirlpools can be addressed by adjusting the integrated radar flow velocity and water level meter to the optimal measurement position, ensuring effective beam coverage of the water surface and preventing changes in the measurement area due to water flow variations from affecting data accuracy. When the water level rises or falls rapidly, the height can be adjusted to maintain the optimal measurement distance. By employing the integrated radar flow velocity and water level meter and camera, the invention overcomes the problems of ultrasonic flow meters being susceptible to interference and experiencing decreased measurement accuracy. It enables long-term, stable, and accurate measurement of water level and flow velocity, providing reliable data support for the safety monitoring of railway flood-prone bridges. Furthermore, the tilt sensor is used to accurately monitor the tilt angle of the bridge piers caused by the impact of water flow, allowing for the timely detection of potential safety hazards.

[0023] A slot 5 is provided on the right side of the front of the movable block 35. A locking block 6 is installed on the left side of the recessed plate 36 at the position corresponding to the slot 5. The left side of the locking block 6 passes through the slot 5 and extends into it to contact the inner wall of the slot 5. A fastening bolt 7 is provided at the bottom of the movable block 35 and is threadedly connected to the locking block 6. By setting the slot 5, the locking block 6 and the fastening bolt 7, it is convenient to remove the monitoring component 4 from the angle adjustment component 3, thereby improving the space occupied by the entire monitoring device during transportation and storage, and ensuring the stability after installation.

[0024] Connecting blocks 8 are installed on the top and bottom of the right side of the mounting shell 1. The two connecting blocks 8 are fixedly connected by a slide rod 9. The moving block 35 is slidably connected to the surface of the slide rod 9.

[0026] The monitoring component 4 includes a connecting plate 41, which is installed on the right side of the annular plate 32. The right side of the connecting plate 41 passes through the concave plate 36 and extends to its outside. A fixing shell 42 is installed on the left side of the bottom of the connecting plate 41.

The radar flow velocity and water level integrated machine 45 and the camera 46 upload the detected signals to the server in real time through the data transmission module 43.

[0027] Camera 46 is used to observe water flow direction, swirling currents, oblique flows, driftwood, floating objects, etc. Radar velocity and water level integrated unit 45 can accurately measure water level and flow velocity. It adopts advanced radar technology, avoiding the interference problems of ultrasonic technology. Tilt sensor 2 is used to monitor the tilt angle of bridge piers and promptly detect abnormal tilting.

This controller 44 can receive instructions from the command center or monitoring platform, parse the instructions through the built-in microprocessor and convert them into control signals, and then start the servo motor 31 and the rotary motor 37 through the controller 44. The controller 44 is electrically connected to the servo motor 31 and the rotary motor 37.

[0029] By analyzing the images captured by camera 46 and the data collected by radar flow rate and water level integrated machine 45, it can be determined whether the equipment angle is appropriate. If the image of camera 46 is blurry or obstructed, its angle and height are adjusted. If the data of radar flow rate and water level integrated machine 45 fluctuates greatly or is abnormal, its angle and height are adjusted.

[0030] When in use, the camera 46, the radar flow velocity and water level integrated machine 45, and the tilt sensor 2 start to collect data in real time.
