Marine diesel engine with anti-overflow function

Abstract

The marine diesel engine with the anti-overflow function comprises a diesel engine body and a water tank, the water tank is installed at the top of the diesel engine body, a water adding opening is formed in the top of the water tank, a water injection hopper matched with the water adding opening is arranged at the position of the water adding opening, and an anti-overflow mechanism is arranged at the bottom of the water injection hopper. The anti-overflow mechanism comprises a guide block located at the bottom of the water injection hopper, and a movable plug movably connected with the guide block is arranged in the guide block. When water is added into the water tank of the diesel engine, the movable plug is impacted by water flow, and the downward protrusion of the movable plug abuts against the inner wall of the guide block, so that the water flow flows into the water tank from the gap between the movable plug and the guide block, and water can be conveniently added into the water tank of the diesel engine; and if water in the water tank enters the guide block, the movable plug is pushed to move upwards, so that a sealing gasket at the top of the movable plug is in contact with the first water passing opening, and the situation that the water in the water tank of the diesel engine overflows can be avoided.

Description

Technical Field

[0001] The utility model relates to the technical field of diesel engines, in particular to a marine diesel engine with an anti-overflow function. Background Art

[0002] The advantages of diesel engines are high torque and excellent fuel economy. The operating process of a diesel engine shares many similarities with gasoline engines, with each cycle also undergoing four strokes: intake, compression, power, and exhaust. However, because diesel engines use diesel fuel, which has a higher viscosity than gasoline and is less prone to evaporation, yet has a lower auto-ignition temperature, the formation and ignition of the combustible mixture differ from gasoline engines. The main difference is that the mixture in the cylinder of a diesel engine is compression-ignited rather than ignited.

[0003] When using an existing marine diesel engine water tank, the water tank is usually fixed to the diesel engine by means of mounting parts, and cooling water is added to the water tank to cool the diesel engine. However, the marine diesel engine will shake with the hull when in use. When the shaking is large, the cooling water in the diesel engine water tank will overflow, resulting in the diesel engine water tank being unable to hold enough cooling water, thus affecting the use of the diesel engine water tank.

[0004] Currently, no effective solutions have been proposed for the problems in related technologies. Utility Model Content

[0005] In view of the problems in the related art, the present invention proposes a marine diesel engine with an anti-overflow function to overcome the above technical problems existing in the existing related art.

[0006] To this end, the specific technical solutions adopted in this utility model are as follows:

[0007] A marine diesel engine with an anti-overflow function comprises a diesel engine body and a water tank. The water tank is mounted on the top of the diesel engine body. A water inlet is provided on the top of the water tank. A matching water filling hopper is provided at the water inlet. An anti-overflow mechanism is provided at the bottom of the water filling hopper. The anti-overflow mechanism comprises a guide block located at the bottom of the water filling hopper. A movable plug with a movably connected structure is provided in the guide block.

[0008] Preferably, the movable plug is of a conical structure, and the bottom end of the movable plug is provided with symmetrically arranged protrusions, and the top of the movable plug is provided with a sealing gasket.

[0009] Preferably, a water inlet 1 connected to the guide block is provided at the bottom of the water injection hopper, a water inlet 2 is provided at the bottom of the guide block, and a travel hole for the movable plug to move is provided in the guide block.

[0010] Preferably, a plurality of evenly distributed rotating shafts are provided inside the water tank, and wave-breaking plates are provided on the outer surfaces of the rotating shafts.

[0011] Preferably, the outer surface of the water tank is connected with reinforcement strips.

[0012] Preferably, the reinforcement strips are located on both sides of the water tank.

[0013] The beneficial effects of the present invention are as follows: when water is added to the water tank of the diesel engine, the water flow impacts the movable plug, and the movable plug protrudes downward and collides with the inner wall of the guide block, so that the water flows into the water tank from the gap between the movable plug and the guide block, so that water can be easily added to the water tank of the diesel engine. After the water adding is completed, when the diesel engine body shakes, if the water in the water tank enters the guide block, it will push the movable plug to move upward, so that the sealing gasket on the top of the movable plug contacts the water outlet, which can prevent the water in the water tank of the diesel engine from overflowing; and the design of the rotating shaft and the wave-breaking plate, when the water tank is shaken, the water therein flows. When the water in the water tank flows, the water passes through the wave-breaking plate on the rotating shaft, driving the wave-breaking plate to rotate. When the wave-breaking plate rotates, the water flows steadily to the inner wall of the water tank, so that the water in the water tank circulates, reduces the surge phenomenon of the water in the water tank, and reduces the shaking caused by the shaking of the environment.
