Description

Technical Field

[0001] The utility model relates to the technical field of marine ships, and particularly relates to a professional marine survey ship device for preventing broken ice from being sucked into a seawater door during winter navigation. Background Art

[0002] Ships usually need to open holes in the outer hull and set up sea chests to suck seawater for use in systems such as the main engine cooling, ballast, and fire fighting on board.

[0003] The suction port of the seawater pump of a general ship is directly arranged in the sea chest, and the seawater pump directly sucks seawater into the ballast, cooling, and fire fighting pipeline systems on board.

[0004] When a ship operates in a polar low-temperature environment (North Sea region), a large number of floating ice blocks are distributed around the hull. If no special consideration is taken, the inlet of the sea chest is easily blocked by sea ice. Once the sea chest is blocked by ice blocks, the seawater pump will not be able to suck in enough seawater, resulting in overheating of the main engine due to lack of cooling water supply, and thus causing the ship to stop sailing.

[0005] In view of the above problems, some ships use gratings in the sea chest to block broken ice and prevent it from entering the inside of the water suction pipe. However, due to the extremely low ambient temperature, ice layers are also likely to freeze on the surface of the grating, seriously affecting the amount of seawater sucked by the water suction pipe and unable to meet the water consumption of the ship. Therefore, there is an urgent need to design a professional marine survey ship device for preventing broken ice from being sucked into a seawater door during winter navigation to solve the above problems. Content of the Utility Model

[0022] In order to enable those skilled in the art to better understand the technical solution of the present utility model, the present utility model will be further introduced in detail below in conjunction with the accompanying drawings.

[0023] As Figures 1-3 shown, a professional marine survey ship device for preventing the inhalation of broken ice by the seawater door during winter navigation provided by an embodiment of the present utility model includes a marine ship 1, and a seachest 2 is arranged on the side of the marine ship 1. A number of screw posts 3 are fixedly arranged around the seachest 2. A filter cup 4 covering the seachest 2 is fixedly arranged on the screw posts 3. Grille holes 7 are arranged on both the side and the bottom of the filter cup 4. A scraper mechanism 8 is arranged at the bottom of the filter cup 4. The scraper mechanism 8 includes a micro motor 11 arranged inside the filter cup 4, and a bush 13 is sleeved on the output shaft of the micro motor 11. A scraper blade 14 is fixedly arranged on the outer wall of one side of the bush 13.

[0024] Specifically, in this embodiment, it includes a marine ship 1, and a seachest 2 is arranged on the side of the marine ship 1. During the seawater navigation of the marine ship, seawater is inhaled to cool down the equipment on the ship by using the seawater. A number of screw posts 3 are fixedly arranged around the seachest 2. The screw posts 3 can be pre-welded on the outside of the seachest 2. The number of welded screw posts 3 can be four, and the four screw posts 3 are circularly distributed on the outside of the seachest 2. A filter cup 4 covering the seachest 2 is fixedly arranged on the screw posts 3. The opening at the top of the filter cup 4 covers the seachest 2, so that the seawater entering the inside of the seachest 2 first passes through the filter cup 4 for filtration. Grille holes 7 are arranged on both the side and the bottom of the filter cup 4. The seawater enters the inside of the filter cup 4 through the grille holes 7, and the grille holes 7 are used to filter the broken ice in the seawater to prevent the broken ice in the seawater from entering the seachest. A scraper mechanism 8 is arranged at the bottom of the filter cup 4. The scraper mechanism 8 includes a micro motor 11 arranged inside the filter cup 4, and a bush 13 is sleeved on the output shaft of the micro motor 11. A scraper blade 14 is fixedly arranged on the outer wall of one side of the bush 13. The scraper mechanism 8 arranged outside the filter cup 4 can scrape the ice layer attached to the outer surface of the filter cup in time, ensuring that the seachest 2 can absorb enough water volume and ensuring better cooling effect for the marine ship equipment. When the seachest 2 inhales seawater, the micro motor 11 is started, so that the micro motor 11 drives the scraper blade 14 to rotate through the bush 13. The scraper blade 14 can scrape the ice layer attached to the bottom and the outer side of the filter cup 4, avoiding the blockage of the grille holes 7 by the ice layer and ensuring that the seachest can enter sufficient water volume.

[0025] A professional marine survey ship device for preventing broken ice from being inhaled by the seawater gate during winter navigation provided by the utility model. A filter cup 4 is arranged outside the sea bottom gate 2, which can filter the seawater inhaled into the ship, thus preventing the broken ice in the seawater in the extremely cold environment from entering the sea bottom gate 2, effectively ensuring the safety of marine ship navigation.

[0026] In this embodiment, a plurality of ear seats 5 are welded on the outer wall of the top of the filter cup 4, and screw holes 6 are arranged on the ear seats 5. The screw column 3 is inserted into the screw holes 6, and nuts are arranged on the screw column 3. When installing the filter cup 4, it is inserted into the screw column 3 on the marine ship through the screw holes 6 on the ear seats 5, and then fixed on the screw column 3 by using nuts, so as to realize the stable installation of the filter cup 4 on the marine ship.

[0027] In this embodiment, the grid holes 7 are divided into high-density mesh holes, medium-density mesh holes and low-density mesh holes. When sailing in different areas, due to different ice species, mesh holes of different densities can be selected to provide the working efficiency of the filter cup 4.

[0028] In this embodiment, a slope 10 is arranged at the bottom edge of the filter cup 4, and the slope 10 is adapted to the inner angle of the scraper 14. The slope 10 here is a 45-degree chamfer structure, which can also make the scraper 14 contact the surface of the filter cup more closely. At the same time, when the scraper 14 is used in combination with the slope, the structure of the scraper 14 itself can also be enhanced, improving the service life of the scraper 14.

[0029] In this embodiment, the scraper 14 is of an L-shaped structure, and the inner surface of the scraper 14 contacts the bottom and side surfaces of the filter cup 4. By using the L-shaped scraper, the scraping of the ice layer on the bottom and side surfaces of the filter cup 4 can be realized at the same time, which is more efficient. The number of scrapers 14 can be more than one. To improve the scraping efficiency, the number of scrapers 14 can also be increased to 2-3.

[0030] In this embodiment, a reinforcing plate 9 is welded at the center of the bottom of the filter cup 4, and through holes are arranged on the reinforcing plate 9. Long bolts 12 for fixing the micro motor 11 are arranged inside the through holes. First, the micro motor 11 is placed inside the filter cup 4, and the operator inserts the long bolts 12 from the bottom of the filter cup 4 into the through holes, realizing the installation of the long bolts 12 on the micro motor 11 on the reinforcing plate 9, ensuring the stability of the operation of the micro motor 11. The micro motor 11 here has excellent waterproof and anti-freezing properties.

[0031] Only some exemplary embodiments of the present utility model have been described by way of illustration. Without doubt, for those of ordinary skill in the art, the described embodiments can be modified in various different ways without departing from the spirit and scope of the present utility model. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present utility model.
