Description

Technical Field

[0001] The utility model belongs to the technical field of ventilation equipment, and particularly relates to a ventilation device for a ship engine room. Background Art

[0002] During the navigation of a ship, in order to maintain the air environment in the engine room, a ventilation device is installed in the engine room of the ship for ventilation and air exchange inside the engine room.

[0003] The waterproof sealing effect of the existing ventilation device for a ship engine room at the air inlet and outlet is poor. Especially in bad weather such as strong winds, heavy rains, and swells, seawater is easily poured into the cabin through the air pipe. When the water waves and rain contact the hull, water is easily poured into the air inlet; at the same time, the diffusion effect of the inhaled air is average. Summary of the Utility Model

[0004] The technical problem to be solved by the utility model is to prevent water from pouring into the ventilation device, improve the waterproof effect of the air inlet and outlet, make the inhaled air evenly diffuse, and extract the hot air above the engine room.

[0005] To solve the above technical problems, the technical scheme adopted by the utility model is as follows: A ventilation device for a ship engine room includes a housing. An air inlet pipe and an exhaust pipe are respectively connected to both ends of the housing. It also includes a first baffle, a second baffle, a ventilation mechanism, and an exhaust component. The first baffle is fixedly connected to the inner wall of the housing near one end of the air inlet pipe, and an air inlet chamber is formed between it and the inner wall of this end face. The air inlet chamber is communicated with the air inlet pipe. The second baffle is fixedly connected to the inner wall of the housing near one end of the exhaust pipe, and an air outlet chamber is formed between it and the inner wall of this end face. The air outlet chamber is communicated with the exhaust pipe. A ventilation chamber is formed between the first baffle and the second baffle. An air outlet is opened on the side wall of the housing adjacent to the air inlet pipe and the exhaust pipe, and the air outlet is communicated with the ventilation chamber. An air suction port is opened on the bottom wall of the air outlet chamber. The ventilation mechanism is arranged in the ventilation chamber, and the exhaust component is arranged in the air suction port.

[0006] Further, the ventilation mechanism includes an air pump, a first fan, and a first filter screen. The air pump penetrates through the first baffle and is communicated between the air inlet chamber and the ventilation chamber. The first filter screen is fixedly connected between the opposite side walls of the first baffle and the second baffle, and is arranged near the air outlet. The first filter screens are symmetrically distributed. The first fan is installed on the upper inner wall of the housing.

[0007] Further, the exhaust component includes a second fan, and the second fan is fixedly connected in the air suction port.

[0008] Further, the inner hole diameter of the air inlet pipe is gradually decreasing towards the end close to the housing. A rubber valve is provided at the connection between the air inlet pipe and the housing. A second filter screen is provided at the port of the air inlet pipe far from the housing.

[0009] Further, a cover plate is hingedly provided on the upper wall of the end of the exhaust pipe away from the housing.

[0010] Further, an electric heating wire is provided in the middle of the ventilation cavity. A connecting plate is provided on the side wall of the housing. The connecting plates are arranged in pairs symmetrically, and fixing holes are formed in the connecting plates.

[0011] After adopting the above structure, the beneficial effects of the present utility model are as follows: For the ventilation cycle inside the ship engine room, the uniform dispersion of the air inhaled by the ventilation device is maintained. The internal structure of the intake pipe and the rubber valve are used to seal the intake end of the intake pipe. The exhaust pipe is blocked by hinging a cover plate at the end, having a certain sealing effect. When the air pump extracts the air in the intake air cavity, the intake air cavity is in a negative pressure state. The intake air cavity absorbs the air outside the ship through the intake pipe. The ventilation mechanism disperses the inhaled air in the ventilation cavity and discharges the air from the air outlet, realizing the uniform dispersion of the air. At one end of the exhaust pipe, the hot air in the upper part of the engine room is extracted through the exhaust component and discharged through the exhaust pipe, realizing the air circulation in the engine room.

[0019] As Figures 1-4 shown, a ship engine room ventilation device includes a housing 1. An air inlet pipe 2 and an exhaust pipe 3 are respectively connected to both ends of the housing 1. It also includes a first baffle 4, a second baffle 5, a ventilation mechanism 6 and an exhaust air assembly 7. The first baffle 4 is fixedly connected to the inner wall of the housing 1 near one end of the air inlet pipe and forms an air inlet chamber 8 between it and the inner wall of this end face. The air inlet chamber 8 is communicated with the air inlet pipe 2. The second baffle 5 is fixedly connected to the inner wall of the housing 1 near one end of the exhaust pipe 3 and forms an air outlet chamber 9 between it and the inner wall of this end face. The air outlet chamber 9 is communicated with the exhaust pipe 3. A ventilation chamber 10 is formed between the first baffle 4 and the second baffle 5. An air outlet 11 is opened on the side wall of the housing 1 adjacent to the air inlet pipe 2 and the exhaust pipe 3. The air outlet 11 is communicated with the ventilation chamber 10. An air suction port 12 is opened on the bottom wall of the air outlet chamber 9. The ventilation mechanism 6 is arranged in the ventilation chamber 10, and the exhaust air assembly 7 is arranged in the air suction port 12. The housing 1 is installed on the upper wall of the engine room, and air exchange is carried out through the air inlet pipe 2 and the exhaust pipe 3 which are communicated at both ends. The first baffle 4 and the second baffle 5 separate the interior of the housing 1. The ventilation mechanism 6 extracts the air in the air inlet chamber 8, pumps the air in the air inlet chamber 8 into the ventilation chamber 10, evenly disperses it into the engine room in the ventilation chamber 10, and uses the exhaust air assembly 7 to extract the air above the engine room and discharge it, realizing air circulation.

[0020] As Figure 2 and 3 shown, in order to evenly disperse the air in the engine room, the ventilation mechanism 6 includes an air pump 13, a first fan 14 and a first filter screen 15. The air pump 13 penetrates through the first baffle 4 and is communicated between the air inlet chamber 8 and the ventilation chamber 10. The first filter screen 15 is fixedly connected between the opposite side walls of the first baffle 4 and the second baffle 5 and is arranged close to the air outlet 11. The first filter screen 15 is symmetrically distributed. The first fan 14 is installed on the upper wall inside the housing 1. The air pump 13 extracts the air in the air inlet chamber 8, pumps the air outside the engine room into the ventilation chamber 10. The first fan 14 rotates in the ventilation chamber 10 to make the inhaled air diffuse, pass through the first filter screen 15 and discharge air from each air outlet 11, realizing the uniform and dispersed flow of air.

[0021] As Figures 2-4 shown, in order to discharge the air in the engine room, the exhaust air assembly 7 includes a second fan 16. The second fan 16 is fixedly connected inside the air suction port 12. On the upper wall of the end of the exhaust pipe 3 far from the housing 1, a cover plate 19 is hinged. Driving the second fan 16 to rotate, the air at the bottom of the housing 1 and above the engine room is extracted. After the gas enters the air outlet chamber 9, it enters the exhaust pipe 3, pushing the cover plate 19 hinged at the port of the exhaust pipe 3 to turn over, and discharging the gas from the exhaust pipe 3. The cover plate 19 blocks rainwater and has a certain waterproof effect on the outer end face of the exhaust pipe 3.

[0022] As Figure 2 and Figure 5As shown in the figure, in order to achieve the waterproof function at the air inlet end of the air inlet pipe 2, the inner hole diameter of the air inlet pipe 2 is arranged to decrease towards the end close to the housing 1. A rubber valve 17 is provided at the connection between the air inlet pipe 2 and the housing 1, and a second filter screen 18 is provided at the port of the air inlet pipe 2 far from the housing 1. The second filter screen 18 protects the air inlet end of the air inlet pipe 2, and uses the internal inclined plane structure to prevent rainwater or surges from remaining in the air inlet pipe 2. At the same time, the rubber valve 17 blocks the air inlet pipe 2 to avoid water from pouring into the air inlet pipe 2. When the air pump 13 pumps air, the rubber valve 17 will open a certain opening to allow air to be inhaled.

[0023] Among them, an electric heating wire 20 is provided in the middle of the ventilation cavity 10. A connecting plate 21 is provided on the side wall of the housing 1. The connecting plates 21 are arranged in pairs symmetrically. Fixing holes 22 are formed in the connecting plate 21. The electric heating wire 20 is used to heat the air entering the ventilation cavity 10. The housing 1 is bolted to the upper wall of the engine room through the fixing holes 22 in the connecting plate 21.

[0024] During specific use, the operator fixes and installs the device on the upper wall inside the engine room through the connecting plate 21, and installs the bolts through the fixing holes 22. The air inlet pipe 2 and the air outlet pipe are respectively connected to the air inlet and outlet 11 of the engine room;

[0025] During air intake, the ventilation mechanism 6 is used to extract the air in the air intake cavity 8, and the air pump 13 is driven to pump the air in the air intake cavity 8 into the ventilation cavity 10. The air intake cavity 8 is in a negative pressure state, and the first fan 14 is driven to rotate in the ventilation cavity 10, so that the air inhaled into the ventilation cavity 10 diffuses. The air passes through the first filter screen 15 and exits from each air outlet 11, realizing the uniform and dispersed flow of air. At the same time, the internal inclined plane structure of the air inlet pipe 2 is used to prevent rainwater or surges from remaining in the air inlet pipe 2. The rubber valve 17 blocks the air inlet pipe 2 to avoid water from pouring into the air inlet pipe 2. When the air pump 13 pumps air, the rubber valve 17 will open a certain opening to allow air to be inhaled;

[0026] During exhaust, the second fan 16 is driven to rotate to extract the air at the bottom of the housing 1 and above the engine room. After the gas enters the air outlet cavity 9, it enters the exhaust pipe 3, pushing the cover plate 19 hinged at the port of the exhaust pipe 3 to turn over, and discharging the gas from the exhaust pipe 3. The cover plate 19 blocks rainwater and has a certain waterproof effect on the outer end face of the exhaust pipe 3. The air circulation in the engine room is realized through the ventilation mechanism 6 and the exhaust component 7.
