Problems solved by technology

This kind of erection method is simple, but has poor adaptability, weak stability, and cumbersome dismantling procedures, high labor intensity and low work efficiency
[0003] The existing technology is basically suitable for fixed ship types. For different ship types, it can only be dismantled and tediously bound multiple times. Moreover, if the sea conditions are not very good during the work process, the height of the instrument entering the water and the height of the instrument cannot be adjusted conveniently. Angle, increasing labor intensity but also reducing work efficiency
[0004] The existing technical products cannot avoid the instrument current measurement error caused by the displacement of the hull or the bad sea conditions, and the instrument cannot be conveniently adjusted during the navigation current measurement. The stability of the instrument naturally cannot meet the requirements, which increases the working time at sea and reduces the accuracy of current measurement.

Embodiment 1

[0031] Such as figure 1 , 2 As shown, the ADCP ocean current survey auxiliary equipment includes an instrument fixing part 1 and a ship's side fixing part 2;

[0032] The fixed part of the instrument includes long steel pipes 11 and short steel pipes 12 connected to each other by studs and internal threads; the ends of the long steel pipes and the short steel pipes are respectively welded with flanges 13, and the long steel pipes are provided with through holes; The spacing is 100mm, and the diameter is 10mm; there is no hole in the short steel pipe; there is an oblong hole on the flange to fix the instrument, and a steel ring is welded on the inside of the flange to protect the rope and control the installation and release of the instrument. process.

[0033] The length of the long steel pipe is 1700mm, the length of the short steel pipe is 1300mm, the diameter of the long steel pipe and the short steel pipe is 40mm, and the wall thickness of the long steel pipe and the sho...

Embodiment 2

[0043] Such as image 3 As shown, the connecting steel pipe is provided with 4 through holes 2111 with a diameter of 11 mm. Four screw rods 22 are used to pass through the through holes on the two connecting steel pipes 211 and the through holes on the horizontal pipe to connect the two fixing parts 21. The overall width of the shelf can be adjusted. At the same time, the fixed part of the instrument is connected with the fixed part of the ship's side; the horizontal pipe is located between the two fixed parts. The through hole on the horizontal tube is equidistant from the through hole on the connecting steel pipe of the fixture.

[0044] All the other structures are the same as in Example 1.

Embodiment 3

[0046] Four fixing parts 21 are arranged in the ship's side fixing part 2, and other structures are the same as in embodiment 1. This device can be applied to ships with any conditions, and can easily adjust the height and angle of the instrument entering the water. By adjusting the width of each fixing part, it can also Fully able to meet the navigation requirements, see Figure 4 .

Abstract

The invention discloses ADCP (Acoustic Doppler Current Profilers) ocean current investigation auxiliary equipment, which comprises an instrument fixing part and a ship side fixing part. The instrument fixing part comprises a long steel pipe and a short steel pipe connected mutually; a sleeve pipe is arranged on the long steel pipe; a horizontal pipe vertical to the sleeve pipe is arranged on the sleeve pipe; the ship side fixing part comprises fixing pieces arranged side by side; the fixing pieces comprise a connecting steel pipe, and a reinforced steel plate a and a reinforced steel plate b arranged on two ends of the connecting steel pipe; at least three through holes are formed in the connecting steel pipe; a screw rod is adopted to penetrate through the through holes in the connecting steel pipe so as to connect the fixing pieces; a steel ring is arranged on the front end of the reinforced steel plate a; two sides of the horizontal pipe on the sleeve pipe of the instrument fixing part penetrate through the steel ring on the front end of the reinforced steel plate a; the instrument fixing part and the ship side fixing part are connected. The equipment provided by the invention can be used for adjusting the height and the angle of an instrument entering water, the instrument discharge error caused by ship displacement or severe sea conditions can be effectively avoided, and the work efficiency and the ocean current measurement accuracy are greatly improved.

Description

technical field [0001] The invention relates to auxiliary equipment for ADCP ocean current investigation, which is mainly applied to the field of intelligent current measurement. Background technique [0002] People pay more and more attention to the physical activities of seawater. The acoustic Doppler ADCP current profiler has multiple functions of fixed point and navigation, multiple water layers, real-time bathymetry and flow measurement, which is very important for people to explore the physical activities of seawater. role. However, ADCP requires to be erected on a ship. According to the two different forms of flow measurement, fixed-point and sailing, in order to achieve stability, the erection methods and requirements are also different; and the types of ocean vessels are different, so there is an urgent need for a Equipment suitable for various vessel conditions, here we call auxiliary equipment for ADCP. Most of the existing auxiliary equipment is only a long rod...
