Description

Technical Field

[0001] The utility model relates to the field of hydrological information data collection, in particular to a hydrological information collection device. Background Art

[0002] Hydrological information includes the depth, velocity and flow of water bodies. Currently, the more commonly used method for collecting hydrological information is to suspend an acoustic Doppler current profiler above the water surface, use the acoustic Doppler principle to measure the frequency shift information of the scattered signal of the stratified water medium, and use the vector synthesis method to obtain the water flow velocity in the vertical profile, that is, the vertical profile distribution of the water flow.

[0003] At present, the installation method of the acoustic Doppler current profiler is mostly to use steel sections welded into a fixed inverted L-shaped bracket, and fix the acoustic Doppler current profiler to the end of the cantilever of the bracket, so that the acoustic Doppler current profiler can be suspended above the water surface. This installation method fixes the acoustic Doppler current profiler at the end of the cantilever. If maintenance personnel need to maintain or replace the acoustic Doppler current profiler in the future, they must climb to the end of the cantilever to operate, which is difficult to operate and inefficient. In addition, during the climbing process, the maintenance personnel may fall into the water, which poses a great safety hazard. Utility Model Content

[0026] See also Figure 1-Figure 4 A hydrological information collection device comprises a foundation 1, a bracket 2 and a monitoring module 3, wherein the bracket 2 comprises a base 21, a vertical frame 22 and a cantilever 23, wherein the upper end of the vertical frame 22 is vertically fixedly connected to the cantilever 23, the cantilever 23 can be suspended above the water body, the lower end of the vertical frame 22 is rotatably connected to the base 21, the side of the base 21 away from the vertical frame 22 is fixedly connected to the foundation 1, the foundation 1 can be buried in the soil on the bank of the water body, thereby providing support and fixation for the entire collection device to prevent the collection device from falling into the water body or being blown down by the wind, the monitoring module 3 comprises a rotating roller 31 and an acoustic Doppler current profiler 32, the rotating roller 31 is rotatably connected to the vertical frame 22, the acoustic Doppler current profiler 32 is arranged at one end of the cantilever 23 away from the vertical frame 22, and a connecting rope 33 is arranged between the rotating roller 31 and the acoustic Doppler current profiler 32 The rotating roller 31 is provided with a rotating handle 34 coaxially fixedly connected and extending out of the vertical frame 22. Because the vertical frame 22 is rotatably connected to the base 21, when the acoustic Doppler current profiler 32 of the acquisition device needs to be maintained or replaced, the vertical frame 22 can be rotated to rotate the cantilever 23 from above the water body to above the land, and then the rotating roller 31 is rotated by rotating the handle 34, and the acoustic Doppler current profiler 32 suspended by the connecting rope 33 can be slowly lowered from the cantilever 23, which is convenient for maintenance personnel to operate. The above design does not require maintenance personnel to climb to contact the acoustic Doppler current profiler 32, and to maintain and replace the acoustic Doppler current profiler 32, thereby making the maintenance and replacement of the acoustic Doppler current profiler 32 simpler and more efficient, and also avoiding the maintenance personnel from falling during the climbing process, thereby improving the safety of the work.

[0027] See also Figure 1 and Figure 2The bracket 2 also includes a locking mechanism 24, which includes a first locking ear 25, a second locking ear 26 and a locking padlock 27. The second locking ear 26 is vertically fixed to the outer side of the vertical frame 22 near the base 21, and the first locking ear 25 is vertically fixed to the surface of the base 21 facing the vertical frame 22. The first locking ear 25 and the second locking ear 26 are at the same horizontal height. The locking beam of the locking padlock 27 can pass through the first locking ear 25 and the second locking ear 26 at the same time to lock the first locking ear 25 and the second locking ear 26. After the locking padlock 27 locks the first locking ear 25 and the second locking ear 26, the relative position of the vertical frame 22 and the base 21 can be fixed, so that when the cantilever 23 is fixed in a state facing the water surface, the vertical frame 22 is prevented from rotating to cause the acoustic Doppler current profiler 32 to shake and affect the monitoring data.

[0028] In order to fix the cantilever 23 in a state facing the shore and land, so as to facilitate maintenance personnel to operate the acoustic Doppler current profiler 32, a third locking ear 28 is also vertically arranged on the outer side of the vertical frame 22 near the base 21. The third locking ear 28 is symmetrically arranged with the second locking ear 26 with the rotation axis of the vertical frame 22 as the axis of symmetry. The locking beam of the locking padlock 27 can pass through the first locking ear 25 and the third locking ear 28 at the same time to lock the first locking ear 25 and the third locking ear 28. After the locking padlock 27 locks the first locking ear 25 and the third locking ear 28, the cantilever 23 can face the shore and land, so as to facilitate maintenance personnel to lower the acoustic Doppler current profiler 32 for operation.

[0029] See also Figure 3 The vertical frame 22 and the cantilever 23 are both made of round tubes. The vertical frame 22 and the cantilever 23 made of round tubes can reduce wind resistance and improve the wind resistance of the collection device. The end of the cantilever 23 away from the vertical frame 22 is connected to an instrument cover 29. The instrument cover 29 is arranged downward. An instrument slot 291 is arranged in the instrument cover 29. The shape of the instrument slot 291 matches the shape of the acoustic Doppler current profiler 32 and can accommodate the acoustic Doppler current profiler 32, so that the acoustic Doppler current profiler 32 can avoid being wetted by rain, thereby extending the working life of the acoustic Doppler current profiler 32.

[0030] In order to prevent rainwater from entering the instrument slot 291 along the edge of the instrument slot 291 and wetting the acoustic Doppler current profiler 32, the depth of the instrument slot 291 is 0.5-1 cm higher than the height of the acoustic Doppler current profiler 32. This height setting can prevent rainwater from sliding into the instrument slot 291.

[0031] In order to prevent the connecting rope 33 from contacting the inner walls of the vertical frame 22 and the cantilever 23 and reduce wear, guide pulleys 231 are provided at the connections between the cantilever 23, the vertical frame 22 and the instrument cover 29, and the connecting rope 33 is in contact with the guide pulley 231. The design of the guide pulley 231 effectively avoids friction loss between the connecting rope 33 and the inner side of the cantilever 23, thereby extending the service life of the connecting rope 33.

[0032] In order to further improve the corrosion resistance of the connecting rope 33, the connecting rope 33 is a plastic-coated steel wire rope. The polymer coating wrapped on the outer layer of the plastic-coated steel wire rope can prevent the acidic substances in rainwater from corroding the internal stainless steel rope core.

[0033] See also Figure 4 The rotating handle 34 includes a connecting rod 35 and a connecting handle 36. One end of the connecting rod 35 is vertically fixedly connected to the rotating shaft of the rotating roller 31 in the vertical frame 22, and the other end is vertically connected to the connecting handle 36. Rotating the rotating handle 34 drives the rotating roller 31 in the vertical frame 22 to rotate.

[0034] In order to lock the rotating roller 31 and fix the position of the acoustic Doppler flow profiler 32, the vertical frame 22 is provided with a locking pin 37 which is arranged to pass horizontally through the vertical frame 22 near the rotating roller 31, and the connecting rod 35 is provided with a second locking hole 373 at a position opposite to the locking pin 37. The locking pin 37 can vertically pass through the connecting rod 35 of the rotating handle 34. After the locking pin 37 passes through the connecting rod 35 of the rotating handle 34, the rotating roller 31 can be prevented from rotating.

[0035] The acoustic Doppler current profiler 32 is precisely constructed and expensive. In order to prevent it from being stolen, a first locking hole 372 is provided at the position of the vertical frame 22 where the locking pin 37 passes through. A locking block 371 is fixedly connected to one end of the locking pin 37. The size of the locking block 371 is larger than the size of the first locking hole 372. The setting of the locking block 371 can prevent the locking pin 37 from passing through the first locking hole 372 and then escaping therefrom. A fixed padlock 374 is connected to the other end of the locking pin 37. After the locking pin 37 passes through the second locking hole 373, the fixed padlock 374 is connected to fix the relative position of the locking pin 37 and the rotating handle 34, so that the acoustic Doppler current profiler 32 cannot be lowered from the end of the cantilever 23, thereby preventing the acoustic Doppler current profiler 32 from being stolen.
