Description

Technical fields:

[0001] This utility model relates to the field of railway bridge hydrological monitoring technology, and in particular to a radar water level measuring device that can automatically steer. Background technology:

[0002] With the development of railway transportation, the safety of railway bridges has become increasingly prominent. Especially during the flood season, changes in water level, flow rate, and velocity under railway bridges are crucial to the safe operation of the bridges.

[0003] Railway lines are long, and in some areas they pass through seasonal river channels or low-lying areas such as canyons and depressions. Historical hydrological observations indicate that these locations may experience floods or other disasters during heavy rains or flood seasons. Therefore, real-time monitoring of these areas is necessary. However, the water flow characteristics of these locations differ significantly from those of common rivers and other bodies of water. First, they are prone to flooding or sudden rises in water levels within a short period, resulting in rapid flood formation. Second, the source of the flood is uncertain, making it impossible to predict the direction of the flood. Traditional hydrological monitoring methods suffer from slow response and low accuracy. Therefore, existing radar technology, as a non-contact measurement method, has advantages such as fast response and high accuracy, and shows broad application prospects in hydrological monitoring.

[0004] However, existing radar flow meters require the flow direction of the observed water to be preset and fixed in advance. The radar's observation direction must be consistent with the water flow direction to ensure the accuracy of the detection data. Therefore, under the above-mentioned terrain and natural conditions, since the direction of the water flow cannot be determined, traditional detection devices with radar flow meters cannot change the radar's orientation in real time according to the water flow direction. As a result, the obtained water flow data is unreliable and there is a possibility of false alarms and missed alarms, which poses a great risk to the safety of bridges along the railway and data collection. Utility model content:

[0005] The purpose of this invention is to provide a radar water level measuring device that can automatically steer, in order to solve the problems existing in the prior art.

[0006] This utility model is implemented by the following technical solution: an automatically steerable radar water level measuring device, including a pole, a crossarm, an electronically controlled pan-tilt unit, a radar flow meter, a water flow direction detection device, a solar panel, and an electronic control module; a solar panel is installed on the top of the pole, a crossarm is fixedly installed on one side of the pole, an electronically controlled pan-tilt unit is fixedly installed on the free end of the crossarm, a radar flow meter is installed on the electronically controlled pan-tilt unit, a water flow direction detection device is fixedly installed below the radar flow meter on the pole, the electronic control module is electrically connected to the angle sensors of the electronically controlled pan-tilt unit, the radar flow meter, and the water flow direction detection device, and the solar panel is electrically connected to the electronic control module.

The fixed part and the telescopic part are rotatably configured. A rudder is fixedly installed at the lower end of the telescopic part. A float is fixedly fitted on the telescopic part and positioned above the rudder. An angle sensor is fixedly installed at the top of the fixed part.

[0008] Furthermore, a telescopic rod is rotatably connected to the free end of the support arm via a bearing. The fixed part of the telescopic rod is fixedly sleeved on the inner ring of the bearing, and the outer ring of the bearing is fixedly connected to the support arm.

[0009] Furthermore, the electronically controlled gimbal includes a mounting base, a pitch adjustment seat, a rotary table, and a rotary motor. The mounting base is fixedly installed on the free end of the horizontal arm by a clamp. The pitch adjustment seat is hinged to the bottom of the mounting base and is tightly fitted with the mounting base. A rotary table is provided below the pitch adjustment seat, and a rotary motor is fixedly installed on the rotary table.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] like Figure 1 As shown: An automatically steerable radar water level measuring device includes a pole 1, a crossarm 2, an electronically controlled pan-tilt unit 3, a radar flow meter 4, a water flow direction detection device 5, a solar panel 6, and an electronic control module 7. A solar panel 6 is installed on the top of the pole 1 to power the electronically controlled pan-tilt unit 3, the radar flow meter 4, the water flow direction detection device 5, and the electronic control module 7. A crossarm 2 is fixedly installed on one side of the pole 1, and the electronically controlled pan-tilt unit 3 is fixedly installed on its free end. The radar flow meter 4 is installed on the electronically controlled pan-tilt unit 3. The crossarm 2 positions the electronically controlled pan-tilt unit 3 and the radar flow meter 4 above it above the monitored water area. A water flow direction detection device 5 is fixedly installed below the radar flow meter 4 on pole 1. The water flow direction detection device 5 is used to detect the direction of the water flow below the radar flow meter 4 and send the signal to the electronic control module 7. The electronic control module 7 then converts the signal into direction data. The electronic control module 7 adjusts the rotation of the electronic control pan-tilt unit 3 according to the direction data so that the detection direction of the radar flow meter 4 is consistent with the water flow direction, making the detection result of the radar flow meter 4 more accurate. The electronic control module 7 is electrically connected to the angle sensor 503 of the electronic control pan-tilt unit 3, the radar flow meter 4, and the water flow direction detection device 5. The solar panel 6 is electrically connected to the electronic control module 7.

[0018] like Figure 2As shown: The electronically controlled pan-tilt unit 3 includes a mounting base 301, a pitch adjustment seat 302, a rotary table 303, and a rotary motor 304. The mounting base 301 is fixedly mounted on the free end of the horizontal arm 2 by a clamp. The pitch adjustment seat 302 is hinged to the bottom of the mounting base 301. The pitch adjustment seat 302 is tightly fitted to the mounting base 301. The pitch angle of the rotary table 303 below can be adjusted by adjusting the axis at the hinge position between the pitch adjustment seat 302 and the mounting base 301, thereby adjusting the orientation angle of the radar flow meter 4. The rotary table 303 is located below the pitch adjustment seat 302, and the rotary motor 304 is fixedly mounted on the rotary table 303. The pitch adjustment seat 302 and the rotary motor 304 are mounted on the rotary table 303. The output shaft of the rotary motor 304 is connected via gear transmission. The rotary motor 304 is a stepper motor. The rotary motor 304 is connected to the electronic control module 7. The electronic control module 7 can process the angle signal fed back by the water flow direction detection device 5 into the angle data of the motor rotation, and adjust it by comparing the difference between the current angle of the rotary motor 304 and the target angle. By driving the rotary motor 304 to rotate, the rotary table 303 is driven to rotate, which in turn drives the radar flow meter 4 below to rotate. It should be noted that the control method and control circuit of the electronic control module 7 to control the rotary motor 304 can be implemented by those skilled in the art using existing control methods and existing control circuits, so they will not be described in detail.

[0019] like Figure 3As shown: The water flow direction detection device 5 includes a support arm 501, a telescopic rod 502, an angle sensor 503, a float 504, and a rudder 505. A horizontally positioned support arm 501 is fixedly installed on the upright 1. The free end of the support arm 501 is rotatably connected to the telescopic rod 502. Specifically, the free end of the support arm 501 is rotatably connected to the telescopic rod 502 via a bearing 506. The fixing part 5021 of the telescopic rod 502 is fixedly sleeved on the inner ring of the bearing 506, and the outer ring of the bearing 506 is connected to the support arm 505. The arm 501 is fixedly connected; the telescopic rod 502 includes a fixed part 5021 and a telescopic part 5022 movably sleeved within the fixed part 5021. The fixed part 5021 and the telescopic part 5022 are synchronously rotated, that is, when the telescopic part 5022 rotates along the axis, the fixed part 5021 also rotates along with it. A rudder 505 is fixedly installed at the lower end of the telescopic part 5022. The rudder 505 is submerged in water when there is water in the lower area. The rudder 505 is used to drive the telescopic rod 502 to move. The water flow direction rotates, and a float 504 is fixedly sleeved on the telescopic part 5022. The float 504 is positioned above the rudder 505. The float 504 ensures that the rudder 505 detects the direction of the upper layer of water flow. The reason why the rudder 505 detects the direction of the upper layer of water flow is that the working principle of the radar flow meter 4 is to detect the water flow velocity by detecting the reflection time difference of the upper layer of water flow. Therefore, the rudder 505 needs to indicate the direction of the upper layer of water flow to ensure the accuracy of detection. An angle sensor 503 is fixedly installed on the top of the fixed part 5021. The angle sensor 503 rotates together with the telescopic rod 502. An electronic gyroscope is installed in the angle sensor 503, which can sense the rotation angle of the angle sensor 503. The angle sensor 503 transmits the angle signal of the rudder 505 below to the electronic control module 7 in real time. The electronic control module 7 adjusts the angle of the rotating table 303 by the rotation angle, thereby controlling the detection direction of the radar flow meter 4 to be consistent with the direction of water flow.

[0020] The electronic control module 7 includes a solar controller, a battery, a main control module, and a communication module. The solar controller is electrically connected to the solar panel 6, the battery, and the main control module. The solar controller can use an existing MPPT integrated control module and is used to power the main control module. The main control module is electrically connected to the communication module, the angle sensor 503, the electronically controlled pan-tilt unit 3, and the radar flow meter 4.
