Description

Technical Field

[0001] The utility model relates to the technical field of water flow measurement, and specifically, to a launching device for an ADCP measuring ship. Background Art

[0002] ADCP, the full name of which is Acoustic Doppler Current Profilers, refers to an acoustic Doppler current profiler, which is a flow measurement device developed in the early 1980s. ADCP has the characteristics of being able to directly measure the velocity profile of a cross-section, not disturbing the flow field, having a short measurement duration, and a large velocity measurement range. Currently, it is used for the investigation of the flow field structure in the ocean and estuaries, velocity and flow measurement, etc.

[0003] When an ADCP measuring ship is in use, it needs to be launched into the river to be measured, and after the measurement is completed, it needs to be towed ashore. On some slopes with a long length or high riverbanks, the operation of launching and landing the ADCP measuring ship is difficult, and the hull slides on the slope under the action of external force, which easily causes frictional damage to the bottom of the ship, and the measuring components at the bottom of the hull are easily damaged. Therefore, there is an urgent need for a launching device for an ADCP measuring ship. Summary of the Invention

[0004] The technical problem to be solved by the utility model is to provide a launching device for an ADCP measuring ship, which facilitates the launching and landing operations of the ADCP measuring ship and prevents frictional damage to the bottom of the ship during launching and landing.

[0005] The utility model provides a launching device for an ADCP measuring ship, which includes a walking frame and a front positioning frame and a rear positioning frame arranged thereon, wherein:

[0006] The walking frame includes a rectangular frame, several cross bars are arranged inside the rectangular frame, a group of longitudinal connecting rods are connected between the two cross bars in the middle, rectangular holes are formed between the cross bars and the longitudinal connecting rods, and a group of directional wheels and a group of universal wheels are arranged on the lower side of the rectangular frame;

[0007] The front positioning frame includes a group of front support rods arranged at the front end of the bottom plate, an upper support rod is arranged above the front support rods, and several vertical rods are vertically connected between the front support rods and the upper support rod;

[0008] The rear positioning frame includes a group of rear retaining frames symmetrically arranged on the upper side of the rear part of the rectangular frame, a gap is left between the two rear retaining frames, and inverted teeth are respectively arranged on the side walls of the two opposite sides thereof.

[0009] Preferably, the rear retaining frame is in a "V" shape.

[0010] Preferably, a reinforcing rod is connected between the longitudinal connecting rod and the rectangular frame.

[0011] Preferably, an included angle of 120-160° is formed between the two front support rods, and the connecting tip protrudes forward.

[0012] Preferably, a hanging ring is provided at the rear side of the rectangular frame, and a pull rope is detachably connected to the hanging ring.

[0013] Preferably, the directional wheel is arranged at the lower front side of the rectangular frame, and the universal wheel is arranged at the lower rear side of the rectangular frame.

[0014] The working principle of the present invention: For the ADCP survey ship launching device of the present invention, when in use, place the ADCP survey ship on the launching device, and connect a towing rope to the hanging ring at the tail of the survey ship and the launching device. Hold the towing rope by hand and make the launching device slide up along the riverbank ramp into the river. The launching device sinks under the action of gravity, and the survey ship floats on the water surface under the action of buoyancy. After the measurement is completed, first tow the towing rope on the survey ship. Under the action of the reverse teeth, the towing rope positions the stern of the ship, so that the stern of the survey ship first catches into the rear positioning frame at the tail of the launching device. At this time, tow the launching device again to make the launching device go up, and the whole survey ship sinks into the launching device. Finally, tow the two ashore together. The reverse teeth installed on the rear baffle can limit the towing rope on the survey ship to prevent it from detaching from the launching device, and can position the stern of the survey ship, which is convenient for the survey ship to return to the launching device and helps to tow it ashore; the rectangular hole is convenient for placing the measuring components at the bottom of the survey ship to prevent the measuring components from being damaged.

[0015] The beneficial effects of the present invention: The ADCP survey ship launching device of the present invention is supported by the walking frame, the front positioning frame and the rear positioning frame position the survey ship, and uses the directional wheel and the universal wheel to walk on the ramp into the water, and separates under the action of gravity and buoyancy for measurement. This device is convenient for the launching and ashore operation of the ADCP survey ship, prevents the bottom of the hull from being damaged by friction during launching and ashore, and protects the measuring components at the bottom of the hull from being damaged.
