After selecting a suitable and safe detection position, first connect the fixed installation support frame with the external installation and fixing device through the fixing holes provided on the fixed installation support frame, so that the device can be stably installed at the edge of the river channel. After the installation is completed, start the second electric push rod symmetrically arranged in the movable adjustment arm, and the two sliding adjustment cards can be made to slide along the inside of the first movable track cross plate through the second electric push rod, so as to indirectly adjust and control the detection and use positions of the first monitoring and adjustment body and the second monitoring and adjustment body.

[0015] 2. The present invention is easy to set up, install and adjust during use. The position area and angle detected by the first monitoring and adjusting body and the second monitoring and adjusting body can be indirectly adjusted and controlled through the arranged movable adjusting arm. The adjustment is easy to use and saves time and effort. When monitoring the water flow without contact, the water flow radar speed meter works based on the principle of Doppler effect and emits a beam of radar waves. When these beams are irradiated to the surface of the water body, scatterers in the water body, such as water droplets and bubbles, will reflect the radar waves and generate echoes. Due to the relative motion between the scatterers in the water flow and the radar, the frequency of the echo will shift, that is, the Doppler frequency shift. By analyzing this frequency shift, the flow velocity of the water flow can be calculated. The water flow radar speed meter can monitor the water flow velocity in real time and continuously, and provide timely and accurate data support. BRIEF DESCRIPTION OF THE DRAWINGS

After selecting a suitable and safe detection position, first connect the fixed installation support frame 3 with the external erection and fixing device through the fixing holes opened on the fixed installation support frame 3, so that the device can be stably erected at the edge of the river channel. After the erection is completed, start the second electric push rod 9 symmetrically arranged in the mobile adjustment arm 4, and the two sliding adjustment card plates 10 can slide along the inside of the first moving track cross plate 8 through the second electric push rod 9, so that the detection and use positions of the first monitoring and adjustment body 1 and the second monitoring and adjustment body 2 can be indirectly adjusted and controlled. Then start the first electric push rod 6, and the first electric push rod 6 can drive the sliding support adjustment arm 24 to slide outward along the inside of the rotating limit adjustment plate 5, so that the erection monitoring mechanism 14 in the first monitoring and adjustment body 1 and the second monitoring and adjustment body 2 moves to the middle position of the river channel water flow; S2. When the detection position of the monitoring mechanism 14 is determined, the fourth electric push rod 25 drives the conical fixed plug column 23 to move downward and insert it into the mud at the bottom of the river to play a fixing role. With the help of the auxiliary fixed installation hole 22, the fixed plug column can be inserted into the auxiliary fixed installation hole 22 and then inserted into the mud at the bottom of the river, so that the limit installation frame 20 can be stably erected, and the fixed plug column 18 can assist in fixing the limit installation frame 20, so that the device is safe and stable when detecting areas with large water flow velocity; S3. After fixed installation, according to the needs of monitoring, synchronously start the second motor 39 in the first monitoring device 16 and the second monitoring device 17 in the first monitoring and adjusting body 1 and the second monitoring and adjusting body 2, and the second motor 39 can drive the rotating adjustment toothed disc 37 to rotate forward and reversely.

After the detection position and spacing of the first monitoring part 27, the second monitoring part 28 and the third monitoring part 29 are adjusted, start the sixth electric push rod 50 in the first monitoring part 27, the second monitoring part 28 and the third monitoring part 29, and drive the rotor flow meter 48 set at the bottom to be inserted into the water flow device through the sixth electric push rod 50.

After the timed monitoring and detection are completed, the rotor flow meter 48 can be fully raised and reset through the fifth electric push rod 34, the third electric push rod 19 and the sixth electric push rod 50. When detection is needed, the rotor flow meter 48 can be inserted into the water flow for detection in real time. When used outdoors for a long time, the protective baffle plate 12 can be used to block and protect the first monitoring device 16 and the second monitoring device 17 in the first monitoring and regulating body 1 and the second monitoring and regulating body 2, so that the device can be used outdoors for a long time and stably. When the rotor flow meter 48 is inserted into the water flow for detection, the water flow radar speed meter 47 set at the bottom of the fixed supporting cross plate 44 can perform auxiliary contactless detection. The two modes of detection are carried out synchronously, so that the detection and monitoring results are more accurate. Example
