Abstract
The invention discloses a self-cooling device for a ship. The self-cooling device for the ship relates to the technical field of ship manufacturing, and comprises a ship body, wherein a water ballast space is arranged in the ship body; a cooling water inlet is formed in the outer side of the lower part of each side of the ship body; a cooling water outlet is formed in the outer side of the upper part of each side of the ship body; a main cooling pipeline is arranged between the cooling water inlet and the cooling water outlet; in the main cooling pipeline, a first stop valve, a first water pump, a second stop valve, a ship main engine and a third stop valve are sequentially connected from the cooling water inlet; a cooling water inlet branch pipeline is connected between the second stop valve and the ship main engine in the main cooling pipeline; a fourth stop valve and a second water pump are connected onto the cooling water inlet branch pipeline; a cooling water return branch pipeline is connected between the ship main engine and a third stop valve; a fifth stop valve is connected onto the cooling water return branch pipeline. The self-cooling device for the ship can solve the problem that sea ice cannot cool the ship main engine or mechanical equipment in winter.
Description
Technical field
The present invention relates to shipbuilding technical field, especially a kind of device for being carried out equipment cooling by the water in boats and ships when seawater is frozen in.
Background technology
The cooling of marine main engine is generally all directly drawn water and is entered boats and ships cooling system and cool marine main engine or mechanical equipment from seawater, and cooled water is finally directly discharged to outboard; In the winter of cold, when north navigation come by boats and ships, sea there is many floating ice, if now by the pipeline of seawater suction boats and ships cooling system; floating ice or trash ice are certain to block pipeline; marine main engine, mechanical equipment etc. cannot obtain enough cooling water expansion tanks and cool, cause main frame or mechanical equipment work mal, time serious, boats and ships cannot continue navigation.
Summary of the invention
The object of this invention is to provide the autologous cooling mechanism of a kind of boats and ships, it can solve sea ice or the trash ice problem that cannot cool marine main engine or mechanical equipment in winter.
In order to solve the problem, the technical solution used in the present invention is:
The autologous cooling mechanism of this boats and ships, comprise hull, the inside of described hull is provided with Ballast Tank, the outside of the ship side bottom of described hull is provided with cooling water inlet, the outside on the ship side top of described hull is provided with cooling water outlet, main cooling line is provided with between described cooling water inlet and described cooling water outlet, in described main cooling line, the first shutoff valve is connected with in turn from described cooling water inlet, first water pump, second shutoff valve, marine main engine and the 3rd shutoff valve, cooling water expansion tank water inlet pipe road is connected with between second shutoff valve and described marine main engine in described main cooling line, the free end on described cooling water expansion tank water inlet pipe road extend in described Ballast Tank, described cooling water expansion tank water inlet pipe road is connected with the 4th shutoff valve and the second water pump, be connected with cooling water expansion tank return branch road between described marine main engine and described 3rd shutoff valve, described cooling water expansion tank return branch road is connected with the 5th shutoff valve.
Owing to have employed technique scheme, the present invention compared with prior art has following beneficial effect:
1, the water of the present invention's Ballast Tank of utilizing boats and ships to have by oneself is as cooling water expansion tank, and a suction culvert is set is communicated with marine main engine system with water return pipeline, when outboard seawater cannot cool in suction cooling duct, opening suction culvert and water return pipeline by the water suction suction culvert in Ballast Tank cools marine main engine system, and cooled water returns Ballast Tank by water return pipeline;
2, low cost of manufacture of the present invention, only need increase the installation that part and pipeline just can complete reserved cooling system.
Accompanying drawing explanation
Fig. 1 is schematic diagram of the present invention.
Detailed description of the invention
Below in conjunction with drawings and Examples, the present invention is further described:
The autologous cooling mechanism of this boats and ships, as shown in Figure 1, comprise hull 1, the inside of hull 1 is provided with Ballast Tank 13, water is had in Ballast Tank 13, the outside of the ship side bottom of hull 1 is provided with cooling water inlet 8, the outside on the ship side top of hull 1 is provided with cooling water outlet 7, main cooling line 15 is provided with between cooling water inlet 8 and cooling water outlet 7, in main cooling line 15, the first shutoff valve 9 is connected with in turn from cooling water inlet 8, first water pump 2, second shutoff valve 3, marine main engine 5 and the 3rd shutoff valve 6, cooling water expansion tank water inlet pipe road 11 is connected with between second shutoff valve 3 and marine main engine 5 in main cooling line 15, the free end on cooling water expansion tank water inlet pipe road 11 extend in Ballast Tank 13, cooling water expansion tank water inlet pipe road 11 is connected with the 4th shutoff valve 10 and the second water pump 4, be connected with cooling water expansion tank return branch road 14 between marine main engine 5 and the 3rd shutoff valve 6, cooling water expansion tank return branch road 14 be connected with the 5th shutoff valve 12, the other end on cooling water expansion tank return branch road 14 stretches in Ballast Tank.
Under normal circumstances, close the 4th shutoff valve 10, with the 5th shutoff valve 12, open the first shutoff valve 9, second shutoff valve 3, the 3rd shutoff valve 6, open the first water pump 2, seawater enters main cooling line 15 from cooling water inlet 8, enters marine main engine 5 and cools, then discharge outboard by the 3rd shutoff valve 6 from cooling water outlet 7 through the first shutoff valve 9, second shutoff valve 3; When having floating ice or trash ice in seawater, close the first shutoff valve 9, second shutoff valve 3, the 3rd shutoff valve 6, open the 4th shutoff valve 10, the 5th shutoff valve 12, start the second water pump 4, water in Ballast Tank 13 is cooled through marine main engine 5 by cooling water expansion tank water inlet pipe road 11 again, finally get back to Ballast Tank from cooling water expansion tank return branch road 14 through the 5th shutoff valve 12, form circulating cooling like this.
