Description

Technical Field

[0001] The present invention relates to a ventilation structure for the engine room repair workshop. Background Art

[0002] The engine room is the heart of a ship. Various equipment in the engine room ensures the normal navigation of the ship and the daily life needs of the crew. These equipment can be divided into systems: main propulsion system and shafting, power system, steam system, auxiliary power system, ship system and other facilities, tools and spare parts.

[0003] The engine room repair workshop is a place where the engine room crew spends a lot of working hours. There are many heat-generating devices inside the engine room and the room temperature is relatively high. In order for the crew to work in a comfortable temperature environment, the repair workshop is often equipped with a unit air conditioner. Generally, the air supply of the air conditioner and the mechanical air supply are two relatively independent systems. Therefore, on this basis, the air supply of the air conditioner and the mechanical air supply require two different air ducts. However, the space on the ship is limited, and setting two air ducts on the ship occupies a relatively large amount of space on the ship. Summary of the Invention

[0004] The purpose of the present invention is to provide a ventilation structure for the engine room repair workshop, which can effectively solve the problem of the air duct occupying the space of the ship in the background art.

[0013] Technical effects of the present invention:

[0014] 1) The ducts for mechanical ventilation and the air supply ducts of the air conditioner are reasonably combined together, and the same pipeline is used for air supply. It can not only use mechanical air supply to ventilate the cabin when the temperature is relatively low, but also use the unit air conditioner to cool down when the room temperature is relatively high. It can be switched arbitrarily without interference with each other. By arranging the same pipeline, materials and space are saved. At the same time, the layout is simple, energy-saving and environmentally friendly;

[0015] 2) By setting the flow splitting mechanism, different unit air conditioners can work conveniently. It is not necessary for each unit air conditioner to work for 24 hours, which reduces the working intensity of each unit air conditioner, and thus avoids reducing the service life of the equipment and increasing the energy consumption of the ship caused by the long-term operation of the unit air conditioner.

The outer surfaces of the cooling pipe 2 and the cooling tube 4 are both covered with heat-insulating materials.

[0029] At the connection between the mechanical output port 102 and the mechanical connection port 202, a sealing gasket is provided.

In the state where none of the unit air conditioners are turned on, the flow splitting plate 504 is located at the center of the cold air groove 404. The inner wall of the horizontal pipe 403 is connected to two baffles 502. The baffles 502 are respectively located on both sides of the cold air groove 404. Of course, the size of the flow splitting plate 504 is slightly smaller than the size of the inner channel of the horizontal pipe 403, so as to facilitate the movement of the flow splitting plate 504 inside the horizontal pipe 403. At the same time, temperature detectors are provided on the lower surfaces of the cooling pipe 2 and the cooling tube 4 to facilitate the detection of the temperature inside the engine room repair workshop.

[0032] Working principle:

[0033] When the weather temperature is relatively high in summer, the air valve 205 is closed and the air conditioner unit 3 is turned on. The individual unit air conditioners start to work. Cold air enters the horizontal pipe 403 from the cold air input port 405 at one end of the horizontal pipe 403. At this time, the cold air pushes the flow splitting plate 504 to slide on the surfaces of the slide rail 501 and the guide rod 506. While moving, the flow splitting plate 504 compresses the spring 507 and deforms until the surface of the flow splitting plate 504 touches the surface of the single plate 502 far from the started unit air conditioner. At this time, the cold air enters the cold air groove 404 from the horizontal pipe 403, then enters the cold air output port 401 from the cold air groove 404, enters the cold air receiving port 203 from the cold air output port 401, enters the non-weight check valve 204 from the cold air receiving port 203, enters the cooling pipe 2 from the non-weight check valve 204, and finally is output to the engine room repair workshop from the cooling port 201 on the lower surface of the cooling pipe 2, completing the cooling of the engine room repair workshop;

[0034] When it is winter and the weather temperature is relatively low, start the fan and open the air valve 205. Under the action of the fan, the external cold air enters the air inlet pipe 1, the cold air enters the air damper 103 from the air inlet pipe 1, enters the muffler 104 from the air damper 103, enters the mechanical output port 102 from the muffler 104, enters the mechanical air connection port 202 from the mechanical output port 102, enters the air valve 205 from the mechanical air connection port 202, then enters the cooling pipe 2 from the air valve 205, and finally is output to the engine room repair workshop through the cooling port 201 on the lower surface of the cooling pipe 2, completing the cooling of the engine room repair workshop. At the same time, under the action of the non-weight check valve 204, it can avoid the impact on the air-conditioning unit 3 during mechanical ventilation, causing damage to the air-conditioning unit 3.
