Problems solved by technology

[0004] Aiming at the influence of floating objects in the water area on the navigation of ships, especially the problem that the floating objects in the water area block the water inlet pipe of the ship, the present invention proposes a ship floating object prevention and control technology that first breaks the floating objects and then removes them by pumping, which has the advantages of simple application and compact structure It is installed at the front end of the ship's water intake pipe, or in front of the ship's propeller, to prevent or reduce the impact of floating objects in the water area on the ship's navigation, and has good practical value.

Embodiment 1

[0023] Implementation example 1, using the fixed device of the present invention to improve the navigability of the ship.

[0024] A certain type of ship, with a displacement of 1,500 tons, is powered by an internal combustion engine. The diameter of the cooling water inlet pipe used is 8 cm, and it is located 0.3 meters below the waterline of the ship. It is often blocked by floating objects in the water area and affects its normal navigation. The cooling water inlet of the ship is transformed into a cuboid of 13 × 13 × 7 cm, and two roller-type underwater shredders with a length of 12 cm and an outer diameter of 6 cm working toothed rollers are installed. The crushing teeth of the two working tooth rollers mesh with each other, and can be smoothly installed into the aforementioned cuboid of 13×13×7 cm. Waterproof bearings are installed on the side walls of the cuboid, and the two ends of the working gear rollers are connected to the aforementioned bearings. One of the worki...

Embodiment 2

[0025] Implementation example 2, using the telescopic device of the present invention to improve the navigability of the ship.

[0026] A certain type of ship, with a displacement of 20,000 tons, has two propelling propellers with a diameter of 3.5 meters. The propellers are often entangled by seasonal outbreaks of seaweed in the sea area where it sails, affecting its normal navigation, and sometimes even forcing it to stop sailing. 0.25 meters in front of the propeller, two row-type underwater shredders with an outer dimension of 3.5×3.5×0.4 meters are installed, and no pipeline filter is connected after the roller underwater shredders. In each roller type underwater shredder, 10 rows of working gear rollers with a diameter of 0.345 meters and a length of 3.45 meters are arranged in the vertical direction. The outermost working tooth roller close to the side frame of the underwater roller shredder turns to the direction of the bow of the ship when it is working, and the steer...

Abstract

The utility model relates to an automatic treatment, suction and removal device for ships to prevent and control floating objects in water areas, which belongs to the field of ship engineering and equipment. Install a roller underwater shredder at the water inlet of the ship's water intake pipe or before the ship's propulsion propeller, and connect the pipeline filter after the shredder. The underwater shredder can rotate in reverse to prevent it from being stuck. When the floating objects in the water reach the water inlet of the ship's water intake pipe, or before the ship propels the propeller, it is first shredded by the working tooth roller of the underwater shredder. Then the floating debris is intercepted by the pipeline filter, and then transported to the ship by a non-clogging pump for centralized disposal or discharge. If the broken fragments of the floating objects in the water area are small enough to no longer affect the water intake and navigation of the ship, they can also be discharged directly without connecting the pipeline filter. The invention can make the ship have the ability to prevent and control various types of floating objects in the water area, and will not be blocked by the floating objects in the water area to block the water intake pipe or entangle the propeller, and has good application prospects.

Description

technical field [0001] The invention belongs to the field of ship engineering and equipment, and relates to a mechanized equipment that is applied to the water inlet pipe of a ship, or before the propeller of a ship, actively breaks up the floating objects in the water area and then sucks and removes them, so as to prevent the floating objects in the water area For the hazards of ship navigation, the normal navigation of the ship is guaranteed. Background technique [0002] The impact of floating objects on the water on the navigation of ships is generally not familiar and understood by people. In fact, it is not sensational that kelp entangles submarines, but it is indeed a huge hazard to ship navigation. All kinds of floating objects in waters, including explosive natural organisms such as seaweed and jellyfish, as well as various discarded plastic items, ropes, fishing nets and other man-made items, are a real and huge hazard to ship navigation. There are many News repo...
