Description

Technical Field

[0001] The utility model belongs to the technical field of ships, and more specifically, it relates to a ship engine room ventilation opening structure. Background Technique

[0002] Currently, the main air inlets and outlets of the ship engine room are mostly manually operated to close. In the event of a fire in the engine room, it is very easy to delay time and cause the fire to spread rapidly. At present, ships do not have automatic closing. When a fire is discovered, it needs to be manually closed. On the one hand, manual operation is too lagging, there is a risk of the fire increasing, and on the other hand, manual operation poses a personal danger.

[0003] In the prior art, there is a technology with the name "An emergency ventilation pneumatic louver for ship ventilation openings" and a publication number of "CN118560635A". This technology relates to the technical field of ship auxiliary equipment, and particularly relates to an emergency ventilation pneumatic louver for ship ventilation openings. It includes a frame, and the frame is rotatably connected with equally spaced fan blades. Gears are arranged on the fan blades. The fan blades are slidably connected with first sealing strips symmetrically distributed centrosymmetrically. Adjacent first sealing strips are in contact and cooperate with each other. The frame is fixedly connected with second sealing strips symmetrically distributed centrosymmetrically. The second sealing strips are in contact and cooperate with adjacent first sealing strips. A cylinder is fixedly connected in the frame through a mounting bracket. In the present invention, through the cooperation of the fan blades and the first sealing strips, when the first sealing strips are adhesively frozen, the cooperation relationship between the fan blades and the first sealing strips is changed immediately at the first time, and the large-area and difficult-to-treat ice adhesion between the gaps is equally divided into small-area adhesions, which is easy to handle and enables the fan blades of the device to open immediately after the ice treatment is completed, improving the reliability of the emergency louver.

[0004] In the prior art, there is a technology with the name "Louver blades of a ship" and a bulletin number of "CN110735588B". This technology belongs to the technical field of ship accessories. It includes a wind guiding plate and a water blocking plate. The cross-sectional shape of the wind guiding plate is semicircular arc-shaped and its wind guiding plate cavity faces downward in the use state. On the left side in the length direction of the wind guiding plate, a wind guiding plate cavity water droplet intercepting groove flange is folded and extended towards the wind guiding plate cavity. The space between the wind guiding plate cavity water droplet intercepting groove flange and the opposite side of the wind guiding plate constitutes a wind guiding plate cavity water droplet intercepting groove; the water blocking plate is fixed to the side of the wind guiding plate facing away from the wind guiding plate cavity at a position corresponding to the left side in the length direction of the wind guiding plate. A water blocking plate wing extends on the right side in the length direction of the water blocking plate. The space between the water blocking plate wing and the side of the wind guiding plate facing away from the wind guiding plate cavity constitutes a water blocking groove. The left side in the length direction of the water blocking plate protrudes from the left edge of the wind guiding plate in a downward inclined state. It ensures that the wind guiding cavity exhibits good ventilation effects and can ideally intercept water droplets; when encountering strong winds and big waves, the water blocking groove of the water blocking plate wing plays an excellent water blocking role.

[0005] However, this technology does not involve the technical problems and technical solutions of the present application. Summary of the Invention

[0024] The following further details the specific embodiments of the present utility model by describing the embodiments with reference to the drawings, including the shapes, structures, mutual positions and connection relationships of the various components involved, the functions of each part, and the working principles:

[0025] As shown in the attached Figure 1 - attached Figure 2As shown in the figure, the utility model relates to a ventilation opening structure for a ship engine room. A window body 2 is installed on the wall 1 of the engine room compartment. The window body 2 is a louver window, which includes a plurality of blades 3. The plurality of blades 3 are connected to an installation rod 4, and the plurality of blades 3 are simultaneously connected to a control frame 5. The control frame 5 is connected to a cylinder 6, and the cylinder 6 is connected to a control component. The control component is connected to a smoke and fire detection component 7 located inside the engine room compartment. For the deficiencies in the prior art, the above structure proposes an improved technical solution. When setting the structure, the main air inlet and outlet of the engine room are respectively provided with window bodies, and the window bodies adopt louver windows that can be conveniently opened and closed. Through the movement control of the blades of the louver window, the opening and closing of the louver window are realized. The opening and closing of the louver window are controlled by a cylinder. The control principle of the entire structure is as follows: The smoke and fire detection component 7 located inside the engine room compartment senses the situation inside the engine room in real time. When a fire breaks out inside the engine room, the smoke and fire detection component 7 can sense the smoke and the temperature of the fire, and quickly send a signal to the control component. The control component controls the telescopic rod of the cylinder 6 to extend. The telescopic rod drives the plurality of blades 3 of the window body 2 to move synchronously, realizing the closing of the window body 2. In this way, the inside and outside of the engine room can be effectively isolated, avoiding the circulation of internal and external air and preventing the spread of the fire. Through the automatic closing of the blades of the window body, not only can the ventilation opening be automatically closed in case of a fire, effectively avoiding major losses caused by the spread of the fire, but also no manual closing operation is required, effectively protecting the personal safety of on-site personnel. The ventilation opening structure for the ship engine room described in the utility model has a simple structure, can timely and effectively sense the fire situation, automatically close the ventilation opening in time, effectively avoid the spread of the fire caused by the circulation of internal and external air in the engine room, reduce losses, and at the same time do not require manual operation to close, ensuring the personal safety of on-site personnel.

[0026] The bottom of the described cylinder 6 is connected to a base 8 located on the inner wall of the wall 1. The base 8 is located at the position of the wall 1 below the window body 2. In the above structure, the base 8 is welded to the wall 1, which is convenient and reliable for arranging the cylinder 6. The cylinder 6 is parallel to the wall 1. In this way, when the telescopic rod of the cylinder expands and contracts under the control of the control component, it can drive the blades of the window body to flip to realize opening and closing.

[0027] Each blade 3 of the described window body 2 is respectively movably hinged to the installation rod 4, and the installation rod 4 is fixed to the side of the window body 2. Each blade 3 is respectively movably hinged to the control frame 5. In the above structure, the blade can rotate relative to the installation rod, and at the same time, the blade 3 is reliably positioned and can only flip.

[0028] The rear part of the control frame 5 is movably connected to the telescopic rod of the cylinder 6 through a connecting member 9. The cylinder 6 is a single-acting cylinder, and the cylinder 6 has a structure of closing when losing air. The cylinder 6 is connected to an air circuit solenoid valve 11, and the air circuit solenoid valve 11 is connected to a control component. In the above structure, the cylinder is of a pneumatic control type, using a single-acting cylinder for control, and the type is of the closing-when-losing-air type. In this way, after the smoke detection component in the engine room senses a fire, it feeds back a signal to the control component. The control component energizes the air circuit solenoid valve 11, disconnecting the air circuit of the compressed air pipeline. At this time, the cylinder loses air; the cylinder 6 is selected as the closing-when-losing-air type, so the cylinder 6 is ventilated, and the blade 3 of the window 2 opens; when losing air, the blade 3 of the window 2 closes, reliably realizing the opening and closing control of the window 2 driven by the cylinder 6. When a fire breaks out inside the engine room, the ventilation can be timely, reliably and automatically closed to avoid the spread of the fire.

[0029] A travel switch 10 is arranged at the position of the wall 1 above the window 2, and the travel switch 10 is connected to a control component. The control component is connected to a fan. In the above structure, the travel switch is used for the feedback of the switch signal of the window and for alarming and for cutting off the fan. Once the window 2 is closed driven by the cylinder 6, the travel switch 10 senses the movement of the window, then the travel switch immediately feeds back a signal to the control component. The control component automatically closes and cuts off the fan, and at the same time issues an alarm.

[0030] One mounting rod 4 is respectively arranged on each side of the window 2 close to it. One side of each blade 3 is movably connected to the mounting rod 4 on one side of the window 2, and the other side of each blade 3 is movably connected to the mounting rod 4 on the other side of the window 2. In the above structure, the mounting rods are arranged on both sides, used to realize reliable connection and support on each side of each blade respectively, ensuring the stability of the installation or rotation of the blade.

[0031] For the ship engine room ventilation opening structure described in the present utility model, the main air inlet and outlet in the engine room are respectively provided with windows. The windows adopt louvers that can be conveniently opened and closed. Through the movement control of the blades of the louvers, the opening and closing of the louvers are realized. And the opening and closing of the louvers are controlled by a cylinder. The control principle of the whole structure is: The smoke and fire detection component 7 located inside the engine room cabin continuously senses the situation inside the engine room. When a fire breaks out inside the engine room, the smoke and fire detection component 7 can sense the smoke and the temperature of the fire, and quickly sends a signal to the control component. The control component controls the telescopic rod of the cylinder 6 to extend. The telescopic rod pushes the multiple blades 3 of the window 2 to move synchronously, realizing the closing of the window 2. In this way, the inside and outside of the engine room can be effectively isolated, avoiding the circulation of internal and external air and preventing the spread of the fire. Through the automatic closing of the blades of the window, not only the automatic closing of the ventilation opening during a fire is realized, effectively avoiding heavy losses caused by the spread of the fire, but also no manual closing operation is required, effectively protecting the personal safety of on-site personnel.
