Description

Technical Field

[0001] The utility model relates to a lifting structure, in particular to a lifting structure of a hydrographic survey ship ADCP, belonging to the technical field of flow measurement equipment. Background Art

[0002] ADCP (Acoustic Doppler Current Profiler) is a new type of ocean current measuring instrument, which is often used for observations in special areas such as cross-sea bridges, offshore wind farms, and hydrological stations. Due to the presence of pile foundations in such areas, the local water flow pattern changes, and the velocity variation range on the back side is greater than that on the front side. The intensity range of silt scouring and silting will change accordingly with the position of the pile foundation. The scouring and silting range is relatively small and mainly concentrated near the pile foundation. It is necessary to use a hydrographic survey ship for monitoring. However, the existing hydrographic survey ship cannot raise or lower the ADCP device according to the water level during the observation process. At the same time, the ADCP device is easily affected by the waves and shakes. The ADCP will shake up and down and left and right, affecting the measurement accuracy.

[0003] Chinese patent application number: CN202222710621.1 discloses an automatic lifting device for ADCP, including: a fixed plate; a slide rail assembly, the slide rail assembly is installed on the fixed plate, and the slide rail assembly is arranged in the vertical direction; a connecting rod, the upper end of the connecting rod can be slidably installed on the slide rail assembly, and the connecting rod is arranged in the vertical direction; an ADCP device, the ADCP device is installed at the lower end of the connecting rod, the ADCP device is extended into the water, the ADCP device can be operably driven to move the connecting rod in the vertical direction, and a buoyancy member is arranged on the ADCP device, and the buoyancy member is used to generate upward buoyancy. Through the cooperation of the buoyancy member, the connecting rod and the slide rail assembly, the ADCP device can be freely raised and lowered in the vertical direction with the rise and fall of the tide, so that the depth of the ADCP device under water remains unchanged, thereby improving the accuracy of the ADCP device during measurement.

[0004] This patent realizes the lifting and lowering of the ADCP device by arranging the slide rail assembly in the vertical direction and then installing the connecting rod on the slide rail assembly. However, the slide rail will inevitably be hit by the water flow when it is exposed to the outside for a long time, which may cause damage to the slide rail and thus affect the sliding of the connecting rod. Therefore, we propose an ADCP lifting structure for a hydrographic survey ship. Utility Model Content

[0023] See also Figure 1-Figure 4 The embodiment of the utility model provides an ADCP lifting structure of a hydrographic survey ship, including a bottom plate 1 and a box body 2. A lifting assembly 3 is arranged outside the box body 2. The lifting assembly 3 includes a hollow seat 31. The hollow seat 31 is fixedly installed on the outer wall of the box body 2. A coil spring 32 is rotatably connected inside the hollow seat 31. One end of the coil spring 32 is fixedly connected to a rope 34. A plurality of rollers 33 are rotatably connected inside the box body 2. The outer wall of each roller 33 contacts the rope 34. The end of the rope 34 away from the coil spring 32 extends to the bottom of the bottom plate 1 and is fixedly connected to a transverse plate 4. Two grooves 6 are symmetrically provided inside the transverse plate 4. A transducer 7 is detachably connected inside one of the grooves 6, and an ADCP body 8 is detachably connected inside the other groove 6. The ADCP body 8 is connected to the transducer 7 through a data line 13. The bottom of the horizontal plate 4 is fixedly connected with an air bag 5, which drives the horizontal plate 4 to float along the water level. At the same time, the horizontal plate 4 drives the rope 34 to slide. Under the elastic force of the coil spring 32, the rope 34 is retracted into the inside of the hollow seat 31, so that the ADCP body 8 can rise and fall freely in the vertical direction with the rise and fall of the tide, further improving the measurement accuracy; the bottom of the bottom plate 1 is fixedly connected with two sleeves 9, and the inside of the two sleeves 9 is slidably connected with a slide plate 10. The bottom of the two slide plates 10 is fixedly connected with a slide bar 11. The bottom ends of the two slide bars 11 extend to the outside of the corresponding sleeves 9 and are fixedly connected with a gravity block 12. The bottoms of the two gravity blocks 12 are fixedly connected to the top of the horizontal plate 4.

[0024] Furthermore, the interior of the two grooves 6 is threadedly connected with a screw rod 14, one end of the two screw rods 14 is fixedly connected to a fixing plate 16, one end of the two screw rods 14 away from the fixing plate 16 extends to the outside of the cross plate 4 and is fixedly connected to a handle 15, by rotating the handle 15, the handle 15 drives the screw rod 14 to rotate, and the screw 14 drives the fixing plate 16 to rotate, so that the fixing plate 16 can fix the position of the transducer 7 and the ADCP body 8, and vice versa.

[0025] Working principle: when the water level rises, under the action of the airbag 5, the cross plate 4 has been floating on the water surface. At this time, the cross plate 4 moves up, and the cross plate 4 drives the rope 34 to rise. Under the elastic force of the coil spring 32, the excess rope 34 is reeled in. At the same time, in order to prevent the coil spring 32 from reeling in all the ropes 34, under the action of the gravity block 12, the cross plate 4 has a downward force, that is, the gravity of the gravity block 12 and the elastic force of the coil spring 32 just offset the buoyancy of the airbag 5, that is, the ADCP body 8 can rise and fall freely in the vertical direction with the tide, further improving the accuracy of the measurement. At the same time, in order to improve the practicability of the device, by rotating the handle 15, the handle 15 drives the screw 14 to rotate, and the screw 14 drives the fixing plate 16 to rotate, so that the fixing plate 16 can fix the position of the transducer 7 and the ADCP body 8, otherwise it can be disassembled.
