When using, fixed support 1 is installed on the unmanned plane shell, and first installation component 2 and second installation component 3 are connected with fixed support 1 respectively through articulation, and flow measuring radar 23 and water level test radar 33 are installed on first installation component 2 and second installation component 3 respectively, and all are connected with control module data communication, and first installation component 2 and second installation component 3 are unfolded from folding state to suitable position, when unmanned plane reaches the space over the specified measurement area, control module starts flow measuring radar 23 and water level test radar 33, and the water flow parameter and water level parameter are measured.

[0024] First installation component 2 and fixed support 1 one end are connected through the hinging mechanism 4. When unfolding, first installation component 2 rotates to suitable position around the hinging mechanism 4, and when folding, first installation component 2 rotates to superposition with fixed support 1 around the hinging mechanism 4.

[0025] The hinging mechanism 4 includes: fixed seat 41, limiting seat 42 and pivot 43, fixed seat 41 has two, two fixed seats 41 are connected with the both sides of the end of first installation component 2 respectively, limiting seat 42 is connected with the end of first installation component 2 and is located between two fixed seats 41, and pivot 43 is fixed to fixed seat 41, fixed support 1 is provided with two connecting arms 11 close to the end of first installation component 2, pivot 43 is fixed to limiting seat 42, pivot 43 extends into connecting arm 11, and pivot 43 can rotate relative to connecting arm 11, the bottom of two connecting arms 11 protrudes first limiting block 12, and first limiting block 12 is used for positioning the included angle between first installation component 2 and fixed support 1 as obtuse angle. When needing to unfold first installation component 2, pivot 43 rotates relative to connecting arm 11, drives first installation component 2 to rotate around pivot 43, until the obtuse angle is formed between first installation component 2 and fixed support 1, and at this time, the first limiting block 12 protruding at the bottom of connecting arm 11 positions first installation component 2, so that it remains in the unfolded position. Conversely, when needing to fold first installation component 2, the positioning effect of first limiting block 12 is overcome, first installation component 2 reversely rotates around pivot 43, until it superposes with fixed support 1.

[0026] The first mounting assembly 2 comprises a first mounting plate 21 and a first cover plate 22. The fixing seat 41 and the limiting seat 42 are mounted on the first mounting plate 21 close to one end of the fixed support 1. The first mounting plate 21 and the first cover plate 22 are buckled to form a first mounting cavity. The first cover plate 22 is provided with a radar transmitting surface on the side away from the first mounting plate 21. The flow measuring radar 23 is installed in the first mounting cavity. The first cover plate 22 is provided with a radar transmitting surface on the outside, which ensures the accurate transmission and reception of radar signals. The first mounting plate 21 and the first cover plate 22 are buckled to form a first mounting cavity. The flow measuring radar 23 is installed in the first mounting cavity and is protected. The radar signal is transmitted to the water surface through the first cover plate 22 to monitor the water flow and collect monitoring data.

[0027] The second mounting assembly 3 is movably connected to the fixed support 1 away from the first mounting assembly 2 through a rotating mechanism 5. The rotating mechanism 5 comprises a first rotating arm 51 and a second rotating arm 52. One end of the first rotating arm 51 and one end of the second rotating arm 52 are respectively hinged to the end of the fixed support 1. The other end of the first rotating arm 51 and the other end of the second rotating arm 52 are connected to the second mounting assembly 3. The first rotating arm 51 is provided with a cavity 513 on the side opposite to the second connecting arm 11. The cavity 513 is provided with a blocking surface 511 beside it. The fixed support 1 is provided with two mounting parts close to the second mounting assembly 3. The two mounting parts are respectively hinged to the first rotating arm 51 and the second rotating arm 52 through rotating shafts. The second mounting assembly 3 can rotate relative to the fixed support 1 with the rotating shaft as the axis. The two mounting parts are provided with second limiting blocks 512 on the side. The second limiting blocks 512 can extend into the cavity 513.

The second limiting block 512 is used for keeping the second mounting assembly 3 in the unfolded state relative to the fixed support 1 by supporting the blocking surface 511. The second mounting assembly 3 is hinged to the fixed support 1 through double rotating arms. When unfolded, the rotating arms drive the cavity 513 to rotate, so that the second limiting block 512 on the fixed support 1 is embedded in the cavity 513 and presses against the blocking surface 511, forming a rigid lock, ensuring that the water level test radar 33 is stably unfolded, and locking the radar emitting angle to the angle of the water surface, so as to accurately monitor the water level data.

[0028] The second mounting assembly 3 comprises a second mounting plate 31 and a second cover plate 32. The second mounting plate 31 is fixed to the first rotating arm 51 and the second rotating arm 52. The second mounting plate 31 and the second cover plate 32 are buckled to form a second mounting cavity. The water level test radar 33 is installed in the second mounting cavity. The second cover plate 32 is provided with a radar transmitting surface on the side away from the second mounting plate 31. When the first rotating arm 51 and the second rotating arm 52 drive the second mounting assembly 3 to rotate so that the radar transmitting surface is parallel to the water surface, the second limiting block 512 is blocked by the blocking surface 511, so that the radar transmitting surface on the second mounting assembly 3 maintains parallel to the water surface, so that the radar can monitor the vertical height of the water level.

[0029] The fixing support 1 is fixedly provided with a cover plate 6 at the top, and a control module is arranged between the cover plate 6 and the fixing support 1.
