Embodiment approach
[0042] Figure 14 It is the second embodiment of the clutch between the pulley drive shaft and the main drive shaft of the present invention. The end of the pulley drive shaft and the main drive shaft is processed into a square shaft, and the square hole slip clutch 39 is installed on the pulley drive shaft , or installed on the end of the main drive shaft, it can slide on it. When the two shafts are connected in parallel, the sleeve slides to the middle position, and the set screw 40 of the square hole sliding clutch is tightened to prevent the sleeve from sliding. When the two shafts are separated, loosen the set screw 40 of the square hole sliding clutch, slide the sleeve to one end, and disengage from the other shaft end, so as to realize the independent movement of the two shafts. The suspension frame is fixedly connected to the steel beam through bolts 34, and the horizontal or vertical movement of the measuring device is realized through the transmission belt and the r...

Abstract
The invention discloses a hydrographic survey device for a small water area, characterized by arranging a fixed mechanism at the side of the water area, fixing a suspension support at the opposite side; a guiding steel rope is arranged between the fixed mechanism and the suspension support; a mobile pulley rack is driven to horizontally move by a driving wheel arranged on a driving belt of the fixed mechanism; the end of the rope is provided with a measurement sensor by the pulleys of the mobile pulley rack; and the rope is reeled or unreeled by rotating the rollers on the fixed mechanism to realize the vertical movement of the measurement sensor; a control disc controls a main transmission shaft and a belt wheel transmission shaft to individually or synchronously rotate by a clutch, and drives the measurement sensor to move horizontally at a constant depth underwater to measure the data of different positions of the fixed depth, or drives the measurement sensor to vertically move at a fixed position to measure the data of different depths. The invention has the advantages of simple structure, convenient usage and movement, safety, reliability, and high data acquisition efficiency, and can be suitable for different work environments of small reservoirs or ponds.
Description
technical field [0001] The invention relates to a hydrological measuring device used in small water areas, and belongs to the technical field of mechanical design, manufacture and testing. Background technique [0002] At present, the relatively mature hydrological equipment used in underwater data acquisition technology can be roughly divided into two types: one is mobile and the other is throwing fixed. The mobile hydrological data measurement equipment is installed on the bilge of the ship when it is in use, and reaches the designated position to be measured by the movement of the ship for data collection. Similar devices are suitable for use in large water areas, and are used in occasions where the specific measurement location is relatively random. The measurement mobility is high, but the corresponding measurement cost is also relatively high. In small waters, the use of this measuring device not only does not give full play to its outstanding mobility, but also incre...
