Description

Technical Field

[0001] This invention relates to the field of natural disaster early warning technology, and in particular to a flash flood and debris flow monitoring device based on phased array radar technology. Background Technology

[0002] Debris flows are special types of floods that occur in mountain valleys and are triggered by sources such as torrential rain, dam breaks, and snowmelt, containing large amounts of mud, sand, and rocks. Debris flows often accompany flash floods, and their rapid onset and swift movement, carrying mud, sand, and rocks, can bury houses, crops, people, and livestock, destroy various facilities, and even bury villages and towns, causing immense harm to people's lives, property, and economic development. Therefore, long-term monitoring of the causative factors of flash floods and debris flows is necessary. Timely early warning signals when monitored variables show anomalies can effectively prevent flash flood and debris flow disasters and reduce loss of life and property.

[0003] Emergency monitoring and early warning equipment for flash floods and debris flows refers to a combination of several instruments, including a water level monitor, a temperature and humidity detector, a rainfall detector, an image capture device, a soil moisture detector, and a control system display screen. These instruments are essential for emergency monitoring and early warning of natural disasters.

[0004] The basic idea of ​​ultrasonic phased array technology comes from radar electromagnetic wave phased array technology. Phased array radar consists of many radiating elements arranged in an array. By controlling the amplitude and phase of each element in the array antenna, the radiation direction of the electromagnetic waves is adjusted, synthesizing a flexible and rapid focused radar beam within a certain spatial range. Ultrasonic phased array transducers consist of an array of multiple independent piezoelectric crystals. An electronic system controls the excitation of each crystal element according to certain rules and timing to adjust the position and direction of the focusing point.

[0005] However, the existing flash flood and debris flow monitoring equipment has a relatively simple structure, and the monitoring equipment cannot be freely adjusted according to the actual installation and use needs, thus affecting the installation and use effect of the monitoring equipment. Summary of the Invention

[0006] The purpose of this invention is to solve the problem that existing monitoring equipment cannot be freely adjusted according to actual installation and use needs, and to propose a flash flood and debris flow monitoring device based on phased array radar technology.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

A column is rotatably connected to the top of the base, and a fixing groove is provided on the top of the base. A fixing mechanism corresponding to the column is fixedly connected in the fixing groove.

[0009] A support rod is slidably inserted into the top of the column, and the top of the support rod is fixedly connected to the bottom of the support plate. A support block is fixedly connected to one side of the column, and the support block is connected to the support plate by turnbuckles. A fixing rod is rotatably connected to the top of the support plate by a rotating rod, and the top of the fixing rod is fixedly connected to the bottom of the mounting plate.

[0010] The top of the support plate is provided with a sliding groove, and a screw is rotatably connected in the sliding groove. A slider is threaded onto the screw, and the slider is connected to the mounting plate through a transmission rod. The two ends of the transmission rod are rotatably connected to the slider and the mounting plate, respectively. One end of the screw passes through the inner wall of the sliding groove and is fixedly connected to a knob. One end of the knob is slidably inserted with a clamping mechanism, and the knob is surrounded by multiple slots corresponding to the clamping mechanism.

[0011] A control box and an ultrasonic phased array module are fixedly connected to the top of the mounting plate. The control box contains a controller, a memory, a positioning module, a communication module, and a power supply. The outputs of the positioning module, the power supply, and the ultrasonic phased array module are all connected to the input of the controller. The output of the controller is connected to the input of the memory. The output of the communication module is bidirectionally connected to the input of the controller.

[0012] Preferably, the fixing mechanism includes a crossbar, on which an L-shaped fixing rod is slidably sleeved, and the column is provided with a plurality of slots corresponding to the L-shaped fixing rod.

[0013] Preferably, a first spring is sleeved on the crossbar, and the two ends of the first spring are fixedly connected to the L-shaped fixing rod and the inner wall of the fixing groove, respectively.

[0014] Preferably, a limit block is fixedly connected to one end of the support rod located inside the column.

[0015] Preferably, both the control box and the ultrasonic phased array module have multiple locking blocks fixedly connected to their bottoms, and the locking blocks are fixedly connected to the top of the mounting plate by locking bolts.

[0016] Preferably, the bottom of the base is fixedly connected to a plurality of fastening blocks, and the fastening blocks are provided with fastening ports.

[0017] Preferably, the clamping mechanism includes a clamping block, on which a clamping rod is slidably inserted. A clamping sleeve is fixedly sleeved at one end of the clamping rod near the support plate, and a pull rod is fixedly connected at the other end of the clamping rod away from the clamping sleeve.

[0018] Preferably, a second spring is sleeved on the lever, and the two ends of the second spring are fixedly connected to the sleeve and the knob, respectively.

[0019] Preferably, a slide rod is fixedly connected inside the slide groove, and the slide block is provided with a through-hole corresponding to the slide rod.

[0020] Beneficial effects:

[0021] 1. The invention incorporates multiple adjustment mechanisms, allowing the monitoring equipment to be freely adjusted according to actual installation needs, thereby effectively improving the installation and usage performance of the monitoring equipment;

[0022] 2.

Multi-parameter synchronous monitoring: Displacement monitoring: Millimeter-level accuracy (e.g., 0.1 mm / year) for detecting surface deformation of mountains (InSAR mode); Flow velocity measurement: Real-time capture of debris flow / flood velocity (range 0.1-10 m / s) using the Doppler effect. Water content analysis: Combining polarimetric radar technology, soil saturation can be retrieved (accuracy up to ±5%). All-weather operation capability: Penetrates clouds, fog, rain, snow, and nighttime environments (wavelength selection in Ku / X bands), unaffected by visible light limitations.

[0031] In this embodiment, a support rod 5 is slidably inserted into the top of the column 4. One end of the support rod 5 located inside the column 4 is fixedly connected to a limit block 17 to prevent the support rod 5 from falling out of the column 4. The top of the support rod 5 is fixedly connected to the bottom of the support plate 2. A support block 6 is fixedly connected to one side of the column 4. The support block 6 is connected to the support plate 2 by a turnbuckle 7 to adjust the height of the support plate 2. A fixing rod 9 is rotatably connected to the top of the support plate 2 by a rotating rod 8. The top of the fixing rod 9 is fixedly connected to the bottom of the mounting plate 3.

[0032] In this embodiment, the top of the support plate 2 is provided with a sliding groove, and a screw 10 is rotatably connected in the sliding groove. A slider 11 is threaded onto the screw 10 to drive the mounting plate 3 to rotate. The slider 11 and the mounting plate 3 are connected by a transmission rod 12. The two ends of the transmission rod 12 are rotatably connected to the slider 11 and the mounting plate 3 respectively. A slide rod 13 is fixedly connected in the sliding groove. The slider 11 is provided with a through hole corresponding to the slide rod 13. One end of the screw 10 passes through the inner wall of the sliding groove and is fixedly connected to a knob 14 to drive the screw 10 to rotate.

[0033] In this embodiment, a locking mechanism is slidably inserted into one end of the knob 14 to fix the knob 14.
