To ensure that the installation part 52 can be located above the river 300, the length of the suspension bar 50 is long; in order to ensure the monitoring accuracy of the hydrological monitor, the height of the suspension rod 50 should not be too high, and the total length of the fixed seat 10 and the movable frame 20 is less than the length of the suspension rod 50.
When the hydrological monitor needs to be disassembled or assembled, the worm 33 of the rotation driving device 30 drives the movable frame 20 to vertically move upwards relative to the fixed seat 10, so that the suspension rod 50 is separated from the constraint of the insertion hole 224, and the suspension rod 50 and the movable frame 20 rotate downwards together; when the suspension rod 50 is out of the constraint of the insertion hole 224 and rotates downwards, under the action of the elastic force of the first elastic element 60, the first elastic element 60 drives the suspension rod 50 to move axially relative to the rotating base, so that the mounting part 52 of the suspension rod 50 cannot be contacted with the ground, the suspension rod 50 is contacted with the buffer part 14 in the process of rotating downwards, and the buffer part 14 moves relative to the limiting plate 13, so that the second elastic element 15 is compressed, and the suspension rod 50 is buffered; after the suspension rod 50 is static, the installation part 52 of the suspension rod 50 is away from the ground by a small distance, and a worker can conveniently install or disassemble the hydrological monitor. Before the suspension rod 50 rotates, the movable frame 20 moves vertically upwards relative to the fixed seat 10, so that the height of the suspension rod 50 is raised integrally, and the installation part 52 cannot be contacted with the ground after the suspension rod 50 rotates.
After the hydrological monitor is installed on the installation part 52, an operator can pull the suspension rod 50 to enable the first elastic piece 60 to be stretched again, the suspension rod 50 is rotated upwards by virtue of the ejector rod, the protruding part 54 on the suspension rod 50 is clamped into the inlet at the top of the guide groove 131, the movable frame 20 is enabled to integrally move vertically downwards by the driving device 30, the protruding part 54 moves along the guide groove 131, the suspension rod 50 is enabled to be inserted into the jack 224 again, the suspension rod 50 is kept at the working position, and the hydrological monitor installed on the installation part 52 can monitor the water level of the river 300.

In other embodiments, the limiting structure may be other structures, for example, the limiting structure is a slot disposed on the movable frame 20, two opposite side walls of the slot limit the vertical rotation of the suspension rod 50, and an end wall in the depth direction of the slot is used to limit the axial movement of the suspension rod 50.
In this embodiment, the guiding groove 131 on the limiting plate 13 extends upward and penetrates through the top end of the limiting plate 13, so that the movable frame 20 moves vertically upward relative to the fixed seat 10 to separate the suspension rod 50 from the limiting structure. In other embodiments, the guiding slot 131 of the position limiting plate 13 can also extend downward and penetrate the bottom end of the position limiting plate 13, so that the suspension rod 50 can be disengaged from the position limiting structure by moving the movable frame 20 vertically downward relative to the fixed seat 10.
In the present embodiment, the guide groove 131 is an inclined groove, and this structure facilitates the sliding of the projection 54 in the guide groove 131. In other embodiments, the guide groove 131 may be a circular arc groove, as long as the protrusion 54 moves along the guide groove 131 to disengage the suspension lever 50 from the stopper structure.
In this embodiment, the buffer 14 can buffer the suspension rod 50. The trajectory that the buffer 14 moves relative to the limiting plate 13 is a circular arc, the center of the trajectory is located on the rotation axis of the rotating seat 40, when the suspension rod 50 rotates downward and contacts with the buffer 14, the buffer 14 will be tangentially erected, so that the resistance of the buffer 14 in the sliding process is small, the compression amount of the second elastic element 15 is increased, and a better buffering effect is achieved.
