Description

Technical Field

[0001] The invention relates to the field of ship ventilation, in particular to a gravity-balanced wind damper for ship ventilation. Background Art

[0002] During a ship's voyage, a good ventilation system is crucial to ensuring cabin air quality and maintaining a suitable working environment. As a key component of the ventilation system, the performance of the ship's ventilation damper directly affects ventilation effectiveness and ship safety.

[0003] Most of the gravity-balanced wind dampers installed for ventilation on existing ships have relatively simple functions and are insufficient in regulating the amount of air entering. It is difficult to automatically adjust the degree of opening according to the wind speed outside the cabin. When the wind speed changes, the amount of air entering cannot be accurately controlled, which can easily lead to unstable ventilation in the cabin and affect the comfort and work efficiency of the staff.

[0004] At the same time, in terms of ship fire safety, the existing gravity-balanced wind dampers lack an effective fire response mechanism. Once a fire occurs, the air circulation cannot be blocked in time, causing the fire to spread rapidly with the help of the air, increasing the difficulty of fire fighting and the safety risk of the ship. In addition, most wind dampers do not have an automatic fire alarm function. When a fire occurs, it is difficult to notify the staff in time, delaying the time to deal with the fire, which may cause serious casualties and property losses. Summary of the Invention

[0030] Furthermore, the opening and closing adjustment device includes an opening and closing wind plate 5, the upper surface of the opening and closing wind plate 5 located on the far left is fixedly connected to a closing column 9, the upper end of the closing column 9 is fixedly connected to an L-shaped rod 10, the side wall of the L-shaped rod 10 is provided with a rotating shaft 11, the left end of the rotating shaft 11 is fixedly connected to a second fixed block 12, and two uprights 13 are symmetrically provided on the left side of the second fixed block 12, the two uprights 13 are fixedly connected with the same long column 14, and the outer surface of the long column 14 is rotatably connected to an adjusting wind plate 15, and the right side wall of the adjusting wind plate 15 is provided with an L-shaped groove 16, and a sliding block 17 is provided in the L-shaped groove 16. The right side wall of the sliding block 17 is fixedly connected to a positioning block 18, and the right side wall of the positioning block 18 is fixedly connected to an anti-slip sheet 19, so that when the upper surface of the adjusting wind plate 15 is exposed to wind, the right side of the adjusting wind plate 15 is pressed downward, and then the L-shaped rod 10 is used to give an upward pulling force to the bottom of the opening and closing wind plate 5, thereby adjusting the opening and closing degree of the wind gate.

[0031] Furthermore, the lower surface of the second fixed block 12 is fixedly connected to the upper surface of the bellows 3, the bottom of the column 13 is fixedly connected to the upper surface of the mounting base 1, and the bottom of the sliding block 17 is fixedly connected to the upper surface of the L-shaped rod 10.

The L-shaped rod 10 is rotatably connected to the rotating shaft 11, so that when the L-shaped rod 10 is subjected to pressure, it can maintain contact with the adjusting wind plate 15 and continuously transmit the changes in wind force to the opening and closing wind plate 5.

[0032] Furthermore, the sealing device includes an opening and closing wind plate 5, the lower surface of the opening and closing wind plate 5 is fixedly connected to a steel rope 20, the lower end of the steel rope 20 is fixedly connected to a hook 21, the surface of the hook 21 is sleeved with a square ring 22, the bottom of the square ring 22 is fixedly connected to a counterweight block 23, and the inner wall of the bellows 3 is fixedly connected to two identical third fixed blocks 24, and the same rope column 25 is fixedly connected between the two third fixed blocks 24, so that the opening and closing wind plate 5 can maintain a stable open state under the tension of the opening and closing spring 7 and the gravity of the counterweight block 23, so that the cabin can be ventilated.

[0033] Furthermore, the fire alarm device includes a counterweight block 23, the rear side wall of the counterweight block 23 is fixedly connected with a clamping claw 26, the inner wall of the clamping claw 26 is slidably connected with a connecting column 27, the bottom end of the connecting column 27 is fixedly connected with a receiving plate 28, the upper surface of the receiving plate 28 is fixedly connected with two identical connecting springs 29, the upper ends of the two connecting springs 29 are fixedly connected with the same connecting plate 30, a buzzer 31 is fixedly installed on the upper surface of the receiving plate 28, an electric wire 32 is placed on the upper surface of the receiving plate 28, a power supply 33 is fixedly installed on the upper surface of the receiving plate 28, a contact block 34 is fixedly installed on the upper surface of the receiving plate 28, and the side wall of the receiving plate 28 is fixedly connected with two symmetrical fixed plates 35. When a fire occurs, the connecting plate 30 does not contact the contact block 34, and the buzzer 31 does not work.

[0034] Further, the upper end of the connecting column 27 is fixedly connected to the inner wall of the air baffle 3, and the electric wire 32 is connected between the communication plate 30 and the buzzer 31, between the buzzer 31 and the power supply 33, and between the power supply 33 and the contact block 34. The upper surface of the fixed plate 35 is fixedly connected to the inner wall of the air baffle 3. When a fire occurs, the counterweight 23 presses the communication spring 29, the communication plate 30 contacts the contact block 34, the circuit forms a closed loop, and the buzzer 31 alarms.

[0035] Further, the hook 21 is made of wood alloy with a melting point of 68-72℃, so that when a fire occurs and the temperature in the cabin rises, the hook 21 can melt, the counterweight 23 is separated from the opening and closing air baffle 5, and the opening and closing air baffle 5 can be completely closed under the tension of the opening and closing spring 7, thereby preventing air from entering.

[0036] Working principle: when the device is used, the mounting seat 1 is placed on the top of the cabin and fixedly installed through the mounting hole 2. Under normal wind conditions, the opening and closing air baffle 5 is in a completely open state under the combined action of the tension of the opening and closing spring 7 and the gravity of the counterweight 23, and the entire air baffle is in a completely open state, so that the cabin can be normally ventilated. When the external wind force increases, the adjusting air baffle 15 is pressed by the wind force, rotates clockwise around the long column 14, the right side of the adjusting air baffle 15 moves downward, thereby pressing the L-shaped rod 10, the L-shaped rod 10 rotates counterclockwise around the rotating shaft 11, the right end of the L-shaped rod 10 moves upward, thereby pulling the bottom of the opening and closing air baffle 5 upward through the closing column 9, and the opening degree of the air baffle decreases. When the external wind force decreases, the tension on the opening and closing air baffle 5 decreases, and the bottom of the opening and closing air baffle 5 moves downward under the action of the gravity of the counterweight 23, so that the opening degree of the air baffle increases, thereby ensuring the stability of the air inflow of the cabin under the condition of change of external wind force. When a fire occurs in the cabin, the temperature in the cabin rises to about 70℃, the hook 21 melts, the counterweight 23 is separated from the opening and closing air baffle 5, the gravity of the opening and closing air baffle 5 is less than the upward tension, the balance state is broken, the bottom of the opening and closing air baffle 5 moves upward until the air baffle is completely closed, thereby blocking the flow of external air to the cabin where the fire occurs. After the counterweight 23 is separated from the opening and closing air baffle 5, it falls vertically downward along the connecting column 27 and lands on the communication plate 30. Under the action of the gravity of the counterweight 23, the communication spring 29 is compressed, the communication plate 30 moves downward until it contacts the contact block 34, a closed loop is formed between the buzzer 31, the power supply 33, the contact block 34 and the communication plate 30, the buzzer 31 works to emit an alarm sound, reminding the staff.
