Description

Technical Field

[0001] The utility model relates to the technical field of flow monitoring equipment, in particular to a flow monitoring device for a hydropower station. Background Art

[0002] After searching the Chinese utility model patent CN21611621 U, a downstream ecological flow monitoring device for a small hydropower station is disclosed, which is provided with a supporting assembly and a monitoring assembly, the supporting assembly includes a base plate, a telescopic support rod vertically fixed in the middle of the upper end of the base plate, a cross bar vertically installed at the upper end of the outer wall of the telescopic support rod, and a control box installed on the upper side of the front end of the outer wall of the telescopic support rod, wherein the middle part of the upper end of the telescopic support rod has a placement groove, and the monitoring assembly includes a camera installed on the lower side of the outer wall of one end of the cross bar, a radar water level meter installed on the lower side of the outer wall of one end of the cross bar and located at the right end of the camera, a radar flow meter installed on the lower side of the outer wall of one end of the cross bar and located at the right end of the radar water level meter, and a line placement box installed on the lower side of the outer wall of the other end of the cross bar. The above arrangement can adjust the height of the control box and the monitoring assembly, and the operator lowers the cross bar to a certain height through the telescopic support rod to facilitate the detection of the control box and the monitoring assembly.

[0003] This patent adjusts the height of the control box and the monitoring component through a telescopic support rod, but the existing telescopic support rod is generally driven by a cylinder. However, during the use of the cylinder, due to factors such as force load, air circuit pressure, piston seal and normal minor leakage, the extended position of the cylinder will not remain in the same position for a long time, resulting in deviation in the shooting and monitoring angle, which will affect the viewing effect and make it impossible to ensure that the device can be in a stable working state.

[0004] To this end, we propose a flow monitoring device for a hydropower station. Utility Model Content

After the operation is completed, the height adjustment rod is rotated in the opposite direction until the connecting sleeve moves to its original state. The whole process requires rotating the height adjustment rod to enable the device to be raised and lowered. The operation is simple, convenient and easy to use, and the overall structure is stable, and the connecting sleeve will not slide down. In addition, due to the self-locking function between the transmission worm wheel and the transmission worm, the stability of the height adjustment rod can be improved.

[0015] (2) This is a flow monitoring device for a hydropower station. During use, the auxiliary wheel can be rotated to rotate the transmission worm, thereby realizing the rotation of the transmission worm wheel and the height adjustment rod. Since the fixed bracket is located on the upper side of the lake surface when working, the drive motor can be turned on during maintenance, and the output end of the drive motor can be rotated in the positive direction. The first transmission gear starts to rotate in the positive direction, and the second transmission gear will drive the fixed bracket to rotate in the positive direction, so that the fixed bracket moves to a position that is convenient for operation, making the device convenient to use.
