Embodiment 1

[0027] Example 1: Hard Stranding

[0028] Each group of drum cutting device 1 is composed of two drums with parallel axes and opposite rotation directions, on which picks are arranged in a checkerboard pattern. The picks arranged in a checkerboard arrangement are staggered, so that the two sides of the cut groove formed are close to symmetry, so as to ensure that the force on both sides of the pick is even. In addition, when the pick cuts the cut groove, the two adjacent cut grooves have been cut out first , thereby reducing the specific energy consumption of cutting. The two rollers rotate relative to each other to offset the cutting resistance in the vehicle length direction, and the roller frame 2 plays a certain protective role, and avoids damage to the hull when the device is close to the stranded hull. In order to prevent the rock cut by the drum cutting device 1 from staying near the drum cutting device 1 and affecting the cutting head to further cut the rock, the drum...

Embodiment 2

[0033] Example 2: Soft Stranding

[0034] The high-pressure water gun 4 is arranged above the absorber 3 and protrudes from the front end of the car body, extending to the front of the drum cutting device 1. It can break up the mud on the bottom of the ship and transport the mud to the rear of the ship through the absorber 3. The high-pressure water pump 8 is arranged on the car body The middle part, the upper part protrudes from the car body to absorb seawater to pressurize, and provides power for the high-pressure water gun. The source of high-pressure water is seawater. The rest of the system works in the same way as in Embodiment 1.

Abstract

Rock-cutting stranding-prevention auxiliary equipment for a ship comprises a crawler-type vehicle body, and is characterized by further comprising two sets of roller cutting devices, two roller frames, an absorber extending out of the crawler-type vehicle body, two stretchable mechanical arms, a centrifugal pump, a motor and a battery set, and the centrifugal pump, the motor and the battery set are arranged in the crawler-type vehicle body. During hard stranding, the rock-cutting stranding-prevention auxiliary equipment assists the stranded ship in removing a sharp area of rocks or cuts out a gentle slope to assist the ship in inclining and escaping from stranding, and cut rocks are conveyed to the back portion of the equipment and get far away from the vehicle body through the absorber. During soft stranding, sludge is dispersed through a high-pressure water gun and rollers together, and the absorber sucks the sludge to assist in sludge removal. The rock-cutting stranding-prevention auxiliary equipment has the characteristics of being efficient in work, small in size and light in weight.

Description

technical field [0001] The invention belongs to the technical field of marine auxiliary equipment, in particular to a marine auxiliary equipment used for underwater cutting of rocks or dredging, so as to make a ship out of a stranded state. Background technique [0002] Ship stranding is one of the serious accidents that ships often encounter during sea voyages. Ships stranded on reefs, shoals and other obstacles that hinder the ship's navigation may cause the ship to stop sailing, damage to the hull, and even cause disastrous consequences of environmental pollution and casualties in severe cases. [0003] The emergency measures for ship grounding are divided into two ways: foreign aid and self-reliance. At present, the form of foreign aid is relatively single, mainly using tugboats for auxiliary de-shallowing. Due to the high daily rent of tugboats, this auxiliary de-shallowing method is not only very It is expensive, and the de-shallowing speed is extremely slow, and it i...
