Description

Technical Field

[0001] The utility model relates to the technical field of oil tanks, in particular to a marine safety oil tank. Background Art

[0002] At present, ships usually use fuel oil as fuel. Ships are equipped with fuel tanks. Fuel oil can be stored in the fuel tanks for use by ships. Fuel tanks are containers for storing oil in fuel equipment. Fuel tanks can be divided into open fuel tanks and closed fuel tanks. The fuel inside the fuel tank is a flammable and explosive product, so many equipment now use explosion-proof fuel tanks.

[0003] The prior art proposes, for example, Chinese patent [application number CN202120451800.0] which discloses a highly firm marine explosion-proof oil tank, comprising a fixed base, an explosion-proof outer box, a fireproof outer box and an inner box, wherein two fixed plates are provided at the top of the fixed base, a rubber pad is fixedly provided on the inner side of the fixed plate, two anti-collision plates are provided at the top of the fixed base, a plurality of movable frames are fixedly provided on the inner side of the anti-collision plates, and a buffer spring is provided inside the movable frame; although the patent can fix the explosion-proof outer box on all sides by setting a fixed plate, a threaded rod and a threaded sleeve, so that the explosion-proof oil tank is fixed more firmly, and the shaking of the ship makes the oil tank unstable and creates a dangerous situation; however, the above patent has certain defects during use, for example, the internal pressure and temperature of the oil tank will increase due to temperature and shaking, which may cause fire or even explosion, and the above patent does not have a structure to deal with this situation. Utility Model Content

[0004] The utility model aims to solve the shortcomings in the prior art and provides a marine safety oil tank.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] A marine safety oil tank comprises a tank body, a hollow groove is provided on the top of the tank body, a fire extinguishing mechanism is provided inside the hollow groove, an oil inlet pipe is fixedly connected to the top of the tank body, the fire extinguishing mechanism comprises a sand box fixedly connected to the inside of the hollow groove, a baffle is hingedly provided on an inner wall of one side of the sand box, a slot is provided on one side of the baffle, a limit frame is fixedly connected to the inner wall of one side of the sand box, a block matched with the slot is slidably connected to the limit frame, a telescopic cylinder is fixedly installed on one side of the sand box, a piston end of the telescopic cylinder extends into the interior of the sand box and is fixedly connected to the block, a temperature sensor is fixedly connected to the bottom of the baffle, a PLC controller is fixedly installed on one side of the sand box, a pressure relief mechanism is fixedly connected to the top of the tank body, a bracket is fixedly connected to the bottom of the tank body, an oil outlet pipe is fixedly connected to the bottom of the tank body, and a valve is provided on the oil outlet pipe.

[0007] Preferably, the pressure relief mechanism includes a pressure relief pipe fixedly connected to the oil tank body, a piston is provided inside the pressure relief pipe, a through hole is opened at the top of the pressure relief pipe, a guide column is slidably connected inside the through hole, a connecting plate is fixedly connected to the bottom of the guide column, the bottom of the connecting plate is fixedly connected to the piston, a pressure relief port is opened on the upper half of the outer surface of the pressure relief pipe, a spring is fixedly connected to the internal top side of the pressure relief pipe, and the bottom of the spring is fixedly connected to the connecting plate.

[0008] Preferably, filter elements are provided inside the oil outlet pipe and the oil inlet pipe.

[0009] Preferably, a sealing cap is threadedly connected to the surface of the oil inlet pipe.

[0010] Preferably, the top of the guide column is fixedly connected to a limiting plate.

[0011] The beneficial effects of the utility model are as follows: when the temperature inside the oil tank body increases, the pressure will increase. When the internal pressure increases to a certain critical value, the pressure can push the piston to move upward. When the piston moves to above the pressure relief port, the pressure is relieved through the pressure relief port to avoid the problem that the oil tank body is damaged due to the increase of internal pressure and temperature caused by temperature and shaking. When the temperature inside the oil tank body is too high or spontaneous combustion causes a fire, the temperature sensor senses it, and the control panel controls the telescopic device to pull the card block to separate it from the card slot, and the sand on the shielding plate will fall off, thereby extinguishing the fire and reducing the possibility of explosion.
