The bottom ends of the support legs are located at the upper end of the limit mounting frame.

[0013] A monitoring method for a river flow monitoring device used in a water conservancy project includes the following steps:

[0014] S1. After selecting a suitable and safe detection position, first connect the fixed installation support frame to an external erection fixing device through the fixing holes opened on the fixed installation support frame, so that the device can be stably erected at the edge position of the river. After the erection is completed, start the second electric push rods symmetrically arranged in the moving adjusting arm. Through the second electric push rods, the two sliding adjusting clamping plates can slide along the inside of the first moving track cross plate, so as to indirectly adjust and control the detection and use positions of the first monitoring and adjusting main body and the second monitoring and adjusting main body. Then start the first electric push rod. Through the first electric push rod, the sliding support adjusting arm can be driven to slide outwards along the inside of the rotating limit adjusting plate, so that the erection monitoring mechanisms in the first monitoring and adjusting main body and the second monitoring and adjusting main body move to the middle position of the river water flow.

[0015] S2. When the detection position of the erection monitoring mechanism is determined, drive the conical fixed insertion column to move downwards through the fourth electric push rod and insert it into the soil at the bottom of the river to play a fixing role. And by means of the auxiliary fixed installation holes opened, the plugging column for fixing can be inserted into the auxiliary fixed installation holes and then into the soil at the bottom of the river, so that the limit installation frame can be stably erected. And the limit installation frame can be assisted to be fixed through the fixed plugging column, so that the device is safe and stable when detecting areas with large water flow velocities.

[0016] S3. After the fixed installation, according to the monitoring needs, start the first monitoring devices and the second motors in the second monitoring devices in the first monitoring adjustment body and the second monitoring adjustment body synchronously. The second motor can drive the rotation adjustment gear disk to rotate forward and backward. The rotation adjustment gear disk rotating forward and backward drives the first moving adjustment gear plates and the second moving adjustment gear plates on both sides to move in opposite directions, thereby driving the first moving adjustment clamping plates and the second moving adjustment clamping plates to slide along the second moving track cross plate towards the outer end of the second moving track cross plate, so that the first monitoring part, the second monitoring part and the third monitoring part for detection can be evenly and equidistantly distributed. After the detection positions and spacings of the first monitoring part, the second monitoring part and the third monitoring part are adjusted, start the sixth electric push rods in the first monitoring part, the second monitoring part and the third monitoring part. The sixth electric push rods drive the rotor type flow velocity meter arranged at the bottom to insert into the water flow inside the river to detect the water flow velocity in the river, and the depth of the rotor type flow velocity meter inserted into the water flow can be adjusted and controlled in real time through the sixth electric push rods. And the second moving track cross plate can be controlled to lift along the limit adjustment frame through the fifth electric push rod, indirectly enabling full adjustment of the area where the rotor type flow velocity meter is detected, ensuring that the rotor type flow velocity meter can fully detect and monitor the water flow velocity at different depth positions in the river. And the rotor type flow velocity meters in the first monitoring part, the second monitoring part and the third monitoring part can be evenly distributed in the river, and can fully detect the water flow at different positions in the river, and enable synchronous detection at multiple points. The first motor can drive the rotation limit adjustment plate to swing, so that the first monitoring adjustment body and the second monitoring adjustment body for detection can be adjusted in real time during the detection process, making the detection range larger and the detection result more accurate. Combining the width and depth of the detection area, the flow rate of the river can be conveniently calculated;

[0017] S4. After the regular monitoring and detection are completed, the rotor type flow velocity meter can be fully lifted and reset through the fifth electric push rod, the third electric push rod and the sixth electric push rod. When detection is needed, the rotor type flow velocity meter can be inserted into the water flow for detection in real time. And when used outdoors for a long time, the protective partition board arranged can play a role in blocking and protecting the first monitoring devices and the second monitoring devices in the first monitoring adjustment body and the second monitoring adjustment body, enabling the device to be used stably outdoors for a long time. And when the rotor type flow velocity meter is inserted into the water flow for detection, the water flow radar speedometer arranged at the bottom of the fixed support cross plate can perform auxiliary non-contact detection, and the two detection modes are carried out synchronously, making the detection and monitoring results more accurate.

[0018] Advantages of the present invention:

[0019] 1. The first monitoring unit, the second monitoring unit, and the third monitoring unit for detection in the present invention can be evenly and equidistantly distributed. Start the sixth electric push rod in the first monitoring unit, the second monitoring unit, and the third monitoring unit. Drive the rotor flowmeter insertion device arranged at the bottom through the sixth electric push rod to insert it into the interior of the water flow, detect the speed of the water flow in the river channel, and the depth of the rotor flowmeter inserted into the water flow can be adjusted and controlled in real time through the sixth electric push rod. The second moving track cross plate can be controlled to lift along the limit adjustment frame through the fifth electric push rod, indirectly enabling full adjustment of the detection area of the rotor flowmeter, ensuring that the rotor flowmeter can fully detect and monitor the flow velocity at different depth positions of the water flow in the river channel. Moreover, the rotor flowmeters in the first monitoring unit, the second monitoring unit, and the third monitoring unit can be evenly distributed in the river channel, fully detecting the water flow at different positions in the river channel, enabling synchronous detection at multiple points, making the detection range larger and the detection results more accurate. Combining the width and depth of the detection area, the flow rate of the river channel can be conveniently calculated. When using the rotor flowmeter to insert into the water flow for detection, the water flow radar speedometer arranged at the bottom of the fixed support cross plate can perform auxiliary non-contact detection, and the two detection modes are carried out synchronously, making the detection and monitoring results more accurate.

[0020] 2. During the use of the present invention, the erection, installation, and adjustment are convenient. The position area and angle of the first monitoring and adjustment main body and the second monitoring and adjustment main body can be indirectly adjusted and controlled through the arranged moving adjustment arm, and the adjustment is convenient, time-saving, and labor-saving. When monitoring without contact with the water flow, the water flow radar speedometer works based on the Doppler effect principle, emitting a beam of radar waves. When these beams irradiate the water surface, scatterers in the water body such as water droplets and bubbles will reflect the radar waves, generating echo waves. Due to the relative motion between the scatterers in the water flow and the radar, the frequency of the echo waves 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 speedometer can monitor the water flow velocity in real time and continuously, providing timely and accurate data support. BRIEF DESCRIPTION OF THE DRAWINGS

The moving and adjusting arms 4 are symmetrically arranged, and the two moving and adjusting arms 4 are slidably arranged on the fixedly installed support frame 3. The first monitoring and adjusting main body 1 and the second monitoring and adjusting main body 2 are respectively arranged on the two moving and adjusting arms 4, and the first monitoring and adjusting main body 1 and the second monitoring and adjusting main body 2 have the same structure. The moving and adjusting arm 4 includes a rotating limit adjusting plate 5, a first electric push rod 6, a first motor 7, a first moving track cross plate 8, a second electric push rod 9, and a sliding adjusting clamping plate 10. The second electric push rods 9 are symmetrically and fixedly installed at the outer ends of the first moving track cross plate 8. The sliding adjusting clamping plates 10 are symmetrically slidably clamped inside the first moving track cross plate 8, and the front ends of the two second electric push rods 9 are respectively fixedly connected to the outer ends of the two sliding adjusting clamping plates 10. The rotating limit adjusting plate 5 is rotatably connected to the side end of the sliding adjusting clamping plate 10 facing away from the first moving track cross plate 8. The first motor 7 is fixedly installed at the bottom end of the sliding adjusting clamping plate 10, and the driving end of the first motor 7 is fixedly connected to the rotating limit adjusting plate 5. The first electric push rods 6 are symmetrically and fixedly installed at the side ends of the rotating limit adjusting plate 5. The fixedly installed support frame 3 is connected to an external erection fixing device through fixing holes opened on the fixedly installed support frame 3, so that the device can be stably erected at the edge position of the river channel. After the erection is completed, the symmetrically arranged second electric push rods 9 in the moving and adjusting arm 4 are started. Through the second electric push rods 9, the two sliding adjusting clamping plates 10 can be made to slide along the inside of the first moving track cross plate 8, so that the detection and use positions of the first monitoring and adjusting main body 1 and the second monitoring and adjusting main body 2 can be indirectly adjusted and controlled.

[0037] As Figure 4 , Figure 5 and Figure 6As shown, the first monitoring and adjusting body 1 and the second monitoring and adjusting body 2 both include a monitoring mechanism 14, and the monitoring mechanism 14 includes a fixed mounting device 15, a first monitoring device 16 and a second monitoring device 17.

The limit plug-in holes 21 are symmetrically inserted into the two sides of the limit installation frame 20, and the auxiliary fixed installation holes 22 are evenly inserted into the two ends of the limit installation frame 20. The fourth electric push rod 25 drives the conical fixed plug column 23 to move downward and insert it into the soil at the bottom of the river to play a fixing role.

[0038] like Figure 7 , Figure 8 and Figure 9As shown, the second monitoring device 17 includes an adjusting part 26, a first monitoring part 27, a second monitoring part 28, and a third monitoring part 29. The first monitoring part 27, the second monitoring part 28, and the third monitoring part 29 are evenly distributed, and the first monitoring part 27, the second monitoring part 28, and the third monitoring part 29 are arranged inside the adjusting part 26. Moreover, the first monitoring part 27, the second monitoring part 28, and the third monitoring part 29 have the same structure. The adjusting part 26 includes a limit guiding column 30, a fixedly connected horizontal plate 31, a limit adjusting frame 32, a second moving track horizontal plate 33, a fifth electric push rod 34, a first moving adjusting clamping plate 35, a first moving adjusting tooth plate 36, a rotating adjusting tooth disc 37, a mounting disc 38, a second motor 39, a second moving adjusting tooth plate 40, and a second moving adjusting clamping plate 43. The fixedly connected horizontal plate 31 is fixedly connected to the outer side of the upper end of the limit adjusting frame 32. The limit guiding column 30 is evenly and fixedly installed on the fixedly connected horizontal plate 31 through bolts. The second moving track horizontal plate 33 is slidably clamped on the limit adjusting frame 32. The fifth electric push rod 34 is evenly and fixedly installed inside the bottom end of the limit adjusting frame 32, and the upper end of the fifth electric push rod 34 is fixedly connected to the bottom end of the second moving track horizontal plate 33. The mounting disc 38 is fixedly installed on the outer side of the middle part of the second moving track horizontal plate 33. The second motor 39 is fixedly installed on the mounting disc 38. The first moving adjusting clamping plate 35 and the second moving adjusting clamping plate 43 are slidably clamped on the second moving track horizontal plate 33. The first moving adjusting tooth plate 36 is fixedly connected to the first moving adjusting clamping plate 35. The second moving adjusting tooth plate 40 is fixedly connected to the second moving adjusting clamping plate 43, and the second moving adjusting clamping plate 43 is located outside the first moving adjusting tooth plate 36.

The driving end of the second motor 39 is fixedly connected to the middle part of the rotating adjusting tooth disc 37, and the rotating adjusting tooth disc 37 is distributed between the first moving adjusting tooth plate 36 and the second moving adjusting tooth plate 40. The side ends of the rotating adjusting tooth disc 37 are respectively meshed and connected with the first moving adjusting tooth plate 36 and the second moving adjusting tooth plate 40. By driving the second motor 39, the rotating adjusting tooth disc 37 can rotate forward and backward. The rotating adjusting tooth disc 37 rotating forward and backward drives the first moving adjusting tooth plate 36 and the second moving adjusting tooth plate 40 on both sides to move in opposite directions, thereby driving the first moving adjusting clamping plate 35 and the second moving adjusting clamping plate 43 to slide along the second moving track horizontal plate 33 towards the outer end of the second moving track horizontal plate 33, so that the first monitoring part 27, the second monitoring part 28, and the third monitoring part 29 for detection can be evenly and equidistantly distributed.

[0039] At the end of the first moving adjustment tooth plate 36 facing away from the first moving adjustment clamping plate 35, a ranging detection disc 41 is fixedly installed. At the connection between the second moving adjustment tooth plate 40 and the second moving adjustment clamping plate 43, a laser ranging sensor 42 is fixedly installed, and the ranging detection disc 41 is located directly in front of the laser ranging sensor 42. Through the set laser ranging sensor 42, the distance between the sensor and the ranging detection disc 41 can be accurately detected, which can assist in controlling and calculating the distance between the first monitoring unit 27 and the third monitoring unit 29.

[0040] As Figure 10 shown, the first monitoring unit 27, the second monitoring unit 28, and the third monitoring unit 29 all include a fixed support cross plate 44, a rotor flowmeter 48, a second dismounting and installing disc 49, and a sixth electric push rod 50. The sixth electric push rod 50 is fixedly installed at the front end of the fixed support cross plate 44, and the front end of the sixth electric push rod 50 penetrates through the fixed support cross plate 44. The rotor flowmeter 48 is fixedly connected to the bottom end of the sixth electric push rod 50 through the second dismounting and installing disc 49 and bolts. Through the sixth electric push rod 50, the depth of the rotor flowmeter 48 inserted into the water flow can be adjusted and controlled in real time, so that the rotor flowmeter 48 can accurately detect and monitor the water flow at different depths. When the water flow passes through the rotor flowmeter 48, a force will be generated to make the rotor in the rotor flowmeter 48 rotate. The rotation speed of the rotor is proportional to the flow velocity of the fluid. Therefore, the flow velocity can be calculated by measuring the rotation speed of the rotor. Furthermore, combined with the relationship between flow velocity and flow rate (flow rate = flow velocity × cross-sectional area of water flow), the flow rate of the river channel can be calculated.

[0041] The sliding support adjustment arm 24 is slidably clamped inside the rotation limit adjustment plate 5, and the driving end of the first electric push rod 6 is fixedly connected to the sliding support adjustment arm 24.

The limit guiding column 30 is slidably clamped inside the limit insertion hole 21. The fixed support cross plates 44 in the first monitoring unit 27 and the third monitoring unit 29 are respectively fixedly connected to the second moving adjustment tooth plate 40 and the first moving adjustment tooth plate 36. The fixed support cross plate 44 in the second monitoring unit 28 is fixedly connected to the middle bottom of the second moving track cross plate 33, playing a role of fixed connection and support.

[0042] The working principle of Embodiment 1 is as follows: After selecting a suitable and safe detection position, the fixed installation support frame 3 is fixedly connected to an external erection fixing device or a driving and moving adjustment device through the fixing holes provided on the fixed installation support frame 3, so that the device can be stably erected at the edge position of the river for detection. After the erection is completed, the second electric push rods 9 symmetrically arranged in the moving adjustment arm 4 are started. Through the second electric push rods 9, the two sliding adjustment clamping plates 10 can slide along the inside of the first moving track cross plate 8, so that the detection positions of the first monitoring adjustment main body 1 and the second monitoring adjustment main body 2 can be indirectly adjusted and controlled. Then, the first electric push rod 6 is started. Through the first electric push rod 6, the sliding support adjustment arm 24 can be driven to slide outwards along the inside of the rotation limit adjustment plate 5, so that the erection monitoring mechanism 14 in the first monitoring adjustment main body 1 and the second monitoring adjustment main body 2 moves to the middle position of the river water flow. When the detection position of the erection monitoring mechanism 14 is determined, the conical fixed insertion column 23 is driven to move downwards by the fourth electric push rod 25 and inserted into the soil at the bottom of the river to play a fixing role. And with the help of the auxiliary fixed installation holes 22 provided, the plugging column for fixing can be inserted into the inside of the auxiliary fixed installation holes 22 and then inserted into the soil at the bottom of the river, so that the limit installation frame 20 can be stably erected. And through the fixed plugging column 18, the limit installation frame 20 can be assisted to be fixed, so that the device is safe and stable when detecting areas with large water flow velocities;

[0043] After being fixedly installed, according to the monitoring requirements, the second motors 39 in the first monitoring and adjusting body 1 and the second monitoring and adjusting body 2, namely the first monitoring device 16 and the second monitoring device 17, are started synchronously. The second motor 39 can drive the rotating adjustment gear disc 37 to rotate forward and backward. The rotating adjustment gear disc 37 rotating forward and backward drives the first moving adjustment gear plates 36 and the second moving adjustment gear plates 40 on both sides to move in opposite directions, thereby driving the first moving adjustment clamping plates 35 and the second moving adjustment clamping plates 43 to slide along the second moving track cross plate 33 towards the outer end of the second moving track cross plate 33, so that the first monitoring part 27, the second monitoring part 28 and the third monitoring part 29 for detection can be evenly and equidistantly distributed. After the detection positions and spacings of the first monitoring part 27, the second monitoring part 28 and the third monitoring part 29 are adjusted, the sixth electric push rods 50 in the first monitoring part 27, the second monitoring part 28 and the third monitoring part 29 are started. The sixth electric push rod 50 drives the rotor type flow velocity meter 48 arranged at the bottom to insert into the water flow of the device to detect the water flow velocity in the river channel. And the depth of the rotor type flow velocity meter 48 inserted into the water flow can be adjusted and controlled in real time through the sixth electric push rod 50. And the second moving track cross plate 33 can be controlled to lift along the limit adjustment frame 32 through the fifth electric push rod 34, indirectly enabling full adjustment of the area detected by the rotor type flow velocity meter 48, ensuring that the rotor type flow velocity meter 48 can fully detect and monitor the water flow velocities at different depth positions in the river channel. And the rotor type flow velocity meters 48 in the first monitoring part 27, the second monitoring part 28 and the third monitoring part 29 can be evenly distributed in the river channel, can fully detect the water flow at different positions in the river channel, and enable multi-point synchronous detection. The first motor 7 can drive the rotating limit adjustment plate 5 to swing, so that the first monitoring and adjusting body 1 and the second monitoring and adjusting body 2 for detection can be adjusted in real time during the detection process, making the detection range larger and the detection result more accurate. Combining the width and depth of the detection area can conveniently calculate the flow rate of the river channel.

[0044] A monitoring method for a river channel flow monitoring device used in a water conservancy project, which includes the following steps:

[0045] S1. After selecting a suitable and safe detection position, first connect the fixed installation support frame 3 to an 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 position of the river. After the erection is completed, start the second electric push rods 9 symmetrically arranged in the moving adjustment arm 4. Through the second electric push rods 9, the two sliding adjustment clamping plates 10 can slide along the inside of the first moving track cross plate 8, so as to indirectly adjust and control the detection and use positions of the first monitoring and adjustment main body 1 and the second monitoring and adjustment main body 2. Then start the first electric push rod 6. Through the first electric push rod 6, the sliding support adjustment arm 24 can be driven to slide outwards along the inside of the rotation limit adjustment plate 5, so that the erection and monitoring mechanism 14 in the first monitoring and adjustment main body 1 and the second monitoring and adjustment main body 2 moves to the middle position of the river flow;

[0046] S2. When the detection position of the erection and monitoring mechanism 14 is determined, drive the conical fixed insertion column 23 to move downward through the fourth electric push rod 25 and insert it into the soil at the bottom of the river to play a fixing role. And by means of the auxiliary fixed installation holes 22 opened, the plugging columns for fixing can be inserted into the auxiliary fixed installation holes 22 and then into the soil at the bottom of the river, so that the limit installation frame 20 can be stably erected. And the limit installation frame 20 can be assisted to be fixed through the fixed plugging column 18, so that the device is safe and stable when detecting areas with large water flow velocities;

[0047] S3. After fixed installation, according to the monitoring needs, the second motors 39 in the first monitoring and adjusting body 1 and the second monitoring and adjusting body 2, i.e., the first monitoring device 16 and the second monitoring device 17, are started synchronously. The second motor 39 can drive the rotation adjustment gear disc 37 to rotate forward and backward. The rotation adjustment gear disc 37 rotating forward and backward drives the first moving adjustment gear plates 36 and the second moving adjustment gear plates 40 on both sides to move in opposite directions, thereby driving the first moving adjustment clamping plates 35 and the second moving adjustment clamping plates 43 to slide along the second moving track cross plate 33 towards the outer end of the second moving track cross plate 33, so that the first monitoring part 27, the second monitoring part 28 and the third monitoring part 29 for detection can be evenly and equidistantly distributed. After the detection positions and spacings of the first monitoring part 27, the second monitoring part 28 and the third monitoring part 29 are adjusted, the sixth electric push rods 50 in the first monitoring part 27, the second monitoring part 28 and the third monitoring part 29 are started. The rotor flow meters 48 arranged at the bottom are driven by the sixth electric push rods 50 to insert into the water flow of the device to detect the water flow velocity in the river channel. And the depth of the rotor flow meters 48 inserted into the water flow can be adjusted and controlled in real time through the sixth electric push rods 50. And the second moving track cross plate 33 can be controlled to lift along the limit adjustment frame 32 through the fifth electric push rod 34, indirectly enabling full adjustment of the area detected by the rotor flow meters 48, ensuring that the rotor flow meters 48 can fully detect and monitor the water flow velocity at different depth positions in the river channel. And the rotor flow meters 48 in the first monitoring part 27, the second monitoring part 28 and the third monitoring part 29 can be evenly distributed in the river channel, enabling full detection of the water flow at different positions in the river channel, and enabling synchronous detection at multiple points. The first motor 7 can drive the rotation limit adjustment plate 5 to swing, so that the first monitoring and adjusting body 1 and the second monitoring and adjusting body 2 for detection can be adjusted in real time during the detection process, making the detection range larger and the detection results more accurate. Combining the width and depth of the detection area, the flow rate of the river channel can be conveniently calculated;

[0048] S4. After regular monitoring and detection are completed, the rotor flow meters 48 can be fully lifted 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 required, the rotor flow meters 48 can be inserted into the water flow for detection in real time. And when used outdoors for a long time, the protective partition board 12 provided can play a role in blocking and protecting 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, enabling the device to be used stably outdoors for a long time. And when the rotor flow meters 48 are inserted into the water flow for detection, the water flow radar speedometer 47 arranged at the bottom of the fixed support cross plate 44 can perform auxiliary non-contact detection. The two detection modes are carried out synchronously, making the detection and monitoring results more accurate. Embodiment

At the bottom end of the first detachable mounting disc 46, a water flow radar speedometer 47 is fixedly installed through a second fixed mounting bolt 45. On the limit mounting frame 20, a protective partition board 12 is fixedly connected through a first fixed mounting bolt 13. At the symmetric bottom ends on both sides of the protective partition board 12, support legs 11 are fixedly installed. The bottom ends of the support legs 11 are located at the upper end of the limit mounting frame 20.

[0050] When implementing this embodiment, after the regular monitoring and detection are completed, the rotor flowmeter 48 can be fully lifted 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 required, the rotor flowmeter 48 can be inserted into the water flow in real time for detection. And when used outdoors for a long time, the protective partition board 12 provided can play a role in blocking and protecting the first monitoring device 16 and the second monitoring device 17 in the first monitoring and adjusting main body 1 and the second monitoring and adjusting main body 2, so that the device can be stably used outdoors for a long time. And when the rotor flowmeter 48 is inserted into the water flow for detection, the water flow radar speedometer 47 arranged at the bottom of the fixed support cross plate 44 can perform auxiliary non-contact detection. The two detection modes are carried out synchronously, making the results of the detection and monitoring more accurate.

A monitoring method for a river flow monitoring device used in a water conservancy project, applicable to the river flow monitoring device for a water conservancy project described in claim 4, characterized in that, It includes the following steps: S1. After selecting a suitable and safe detection position, first connect the fixed installation support frame (3) to an external erection 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 position of the river channel. After the erection is completed, start the second electric push rods (9) symmetrically arranged in the moving adjusting arm (4). Through the second electric push rods (9), the two sliding adjusting clamping plates (10) can slide along the inside of the first moving track cross plate (8), so as to indirectly adjust and control the detection and use positions of the first monitoring and adjusting main body (1) and the second monitoring and adjusting main body (2). Then start the first electric push rod (6).

When the detection position of the erection monitoring mechanism (14) is determined, drive the conical fixed insertion column (23) to move downwards through the fourth electric push rod (25) and insert it into the soil at the bottom of the river to play a fixing role. And by means of the auxiliary fixed installation holes (22) opened, the plugging column for fixing can be inserted into the auxiliary fixed installation holes (22) and then into the soil at the bottom of the river, so that the limit installation frame (20) can be stably erected. And through the fixed plugging column (18), the limit installation frame (20) can be assisted to be fixed, so that the device is safe and stable when detecting areas with large water flow velocities; S3. After fixed erection, according to the monitoring needs, synchronously start the second motors (39) in the first monitoring device (16) and the second monitoring device (17) of the first monitoring and adjusting main body (1) and the second monitoring and adjusting main body (2).

And the sixth electric push rod (50) can adjust and control the depth of the rotor flowmeter (48) inserted into the water flow in real time. And the fifth electric push rod (34) can control the second moving track cross plate (33) to lift along the limit adjustment frame (32), indirectly enabling full adjustment of the detection area of the rotor flowmeter (48), ensuring that the rotor flowmeter (48) can fully detect and monitor the water flow velocity at different depth positions in the river channel. And the rotor flowmeters (48) in the first monitoring part (27), the second monitoring part (28) and the third monitoring part (29) can be evenly distributed in the river channel, can fully detect the water flow at different positions in the river channel, and enable multi-point synchronous detection. The first motor (7) can drive the rotation limit adjustment plate (5) to swing, so that the first monitoring and adjusting main body (1) and the second monitoring and adjusting main body (2) for detection can be adjusted in real time during the detection process, making the detection range larger and the detection result more accurate. Combining the width and depth of the detection area, the flow rate of the river channel can be conveniently calculated; S4. After the timing monitoring and detection are completed, the fifth electric push rod (34), the third electric push rod (19), and the sixth electric push rod (50) are used to fully raise and reset the rotor flowmeter (48). When detection is required, the rotor flowmeter (48) can be inserted into the water flow in real time for detection. And when used outdoors for a long time, the protective partition board (12) provided can play a role in shielding and protecting the first monitoring device (16) and the second monitoring device (17) in the first monitoring and adjustment main body (1) and the second monitoring and adjustment main body (2), so that the device can be stably used outdoors for a long time.
