[0033] Furthermore, in the description of the present invention, unless otherwise specified, “plurality” means two or more.
[0034] See also Figures 1 to 9 , the present application provides a ship ventilation device, comprising:
[0035] The ventilation duct 200 includes an inlet, a water outlet 300 and an air outlet 400; the ventilation duct 200 is arranged in a horizontal direction;
[0036] The inlet is provided at the top of the ventilation duct 200 and is used to introduce gas or water;
[0037] The water outlet 300 and the air outlet 400 are both disposed at the bottom of the ventilation duct 200, and the water outlet 300 and the air outlet 400 are respectively disposed at two sides of the ventilation duct 200;
[0038] A plurality of water baffles are arranged in the ventilation duct 200, and the water baffles are arranged between the water outlet 300 and the air outlet 400, and the inlet and the water outlet 300 are arranged on the same side of the water baffles; the water baffles are arranged vertically, and the bottom of the water baffles is fixedly connected to the bottom surface of the ventilation duct 200, and the water baffles are used to limit the flow of water to the side of the air outlet 400. The height of the water baffles is less than the height of the ventilation duct 200, and the top of the water baffles forms a ventilation flow channel 211 to achieve the separation of water and air.
[0039] The gas flows through the top of the water baffle to the air outlet 400 for discharge, and the water flows out from the water outlet 300 on the other side of the water baffle.
[0040] In one practicable manner, Figure 3 and Figure 4 As shown, the bottom plate of the ventilation duct 200 is tilted, and one side of the water outlet 300 is lower than one side of the air outlet 400, so that water entering the ventilation device flows along the bottom plate to the water outlet 300 for discharge, ensuring that the remaining water in the ventilation duct 200 can be drained.
[0041] In one practicable manner, a plurality of water baffles are arranged in the ventilation duct 200, including at least a first water baffle, a second water baffle and a third water baffle in the direction from the water outlet 300 to the air outlet 400. A first water outlet is arranged at the bottom of the first water baffle, and a second water outlet is arranged at the bottom of the second water baffle. Through the arrangement of the water outlets, the seawater in the ventilation duct 200 can flow to the water outlet 300 for discharge.
[0042] In one practicable manner, a first check valve 502 is provided at the first water outlet, and a second check valve 502 is provided at the second water outlet. The check valves are provided to prevent the water level on one side of the ventilation duct 200 from flowing to the air outlet 400 when the water level rises.
[0043] In an practicable manner, in this embodiment, a main drainage cavity 221 is formed between the first water baffle and the drainage port, and most of the seawater entering through the inlet is mainly discharged through the main drainage cavity 221. A secondary drainage cavity 222 is formed between the first water baffle and the second water baffle, and a tertiary drainage cavity 223 is formed between the second water baffle and the third water baffle.
[0044] It should be noted that the number of drainage cavities and water retaining plates is determined according to the specific working conditions of the installation location.
[0045] In an practicable manner, the water outlet 300 and the inlet are respectively disposed at the bottom and the top of the main drainage chamber 221 .
[0046] In an practicable manner, a third check valve 501 is provided at the water outlet 300 to prevent the seawater discharged from the ventilation device from flowing back into the ventilation duct 200 .
[0047] In an practicable manner, the inlet includes a ventilator 100 and an emergency closing unit 600 disposed on the top of the ventilator 100. The emergency closing unit 600 is used to close the inlet when the water volume continues to increase, and automatically open when the water volume decreases to a predetermined value.
[0048] Specifically, Figures 5 to 9As shown, the emergency closing unit 600 includes a cover plate 601, a transmission member and a float 605. The cover plate 601 is disposed on the top of the ventilator 100, and a plurality of transmission members are disposed around the cover plate 601, and the bottoms of the plurality of transmission members are connected to the float 605.
[0049] In an operative manner, the transmission member comprises a first connecting rod 602, a second connecting rod and a third connecting rod 603, one end of the first connecting rod 602 is hinged to the side of the cover plate 601 via a first hinge point 606, the other end of the first connecting rod 602 is hinged to one end of the second connecting rod via a second hinge point 607, the other end of the second connecting rod is fixedly connected to one end of the third connecting rod 603 via a fixed point 608 to form an L-shaped connecting rod, a sliding groove is arranged on the third connecting rod 603, connecting bolts are inserted into the sliding grooves of a plurality of third connecting rods 603, and the connecting bolts can slide in the sliding grooves; a through hole is arranged on the connecting bolt, a fourth connecting rod 604 is inserted into the through hole, a first limit block and a second limit block are respectively arranged on the upper and lower parts of the fourth connecting rod 604, and the bottom of the fourth connecting rod 604 is fixedly connected to the float 605.
[0050] It should be noted that the fixed point 608 is a fixed rotating bolt.
[0051] In one practicable manner, Figure 6 and Figure 7 As shown, the fixing point 608 is higher than the connecting bolt.
[0052] In another possible implementation, Figure 8 and Fig. 9 As shown, the fixing point 608 is below the connecting bolt.
[0053] The initial position of the connecting bolt is at the bottom of the chute. When the liquid level in the ventilator 100 rises, the float 605 rises with the liquid level, and the fourth connecting rod 604 pushes the connecting bolt from the bottom of the chute to the top of the chute, the distance between the multiple fixed points 608 increases, and the distance between the multiple second hinge points 607 decreases and moves downward, thereby driving the top of the first connecting rod 602 to move downward, and realizing the emergency closure of the cover plate 601.
[0054] When the liquid level in the ventilation duct 100 drops to a predetermined position, the float 605 descends under the action of its own gravity, and the fourth connecting rod 604 drives the connecting bolt to move downward. The distance between the multiple fixed points 608 becomes smaller, and the distance between the multiple second hinge points 607 becomes larger and abuts against the inner wall of the ventilation duct 100, so that the second hinge point 607 moves upward, thereby driving one end of the first connecting rod 602 to move upward, and the cover plate 601 opens again.
[0055] In one practicable manner, three or five transmission members are disposed on the circumference of the cover plate 601 to ensure that the cover plate 601 can be opened and closed stably.
[0056] It should be noted that the cover plate 601 is made of a lightweight material and is easy to open and close.
[0057] In one practicable manner, the float 605 is connected to the transmission member via the fourth connecting rod 604. By controlling the length of the fourth connecting rod 604, different opening and closing liquid levels are set to meet a variety of needs.
[0058] In summary, the ship ventilation device provided by the present application can continuously provide air ventilation after the ventilation tube is submerged for a short time, and can effectively prevent water from flowing out of the air outlet by separating air and water in multiple stages. By setting up the emergency closing unit, the present application can automatically open and close according to the water level in the ventilation duct. And the structure of the ventilation duct of the present application is not limited, so it can be effectively matched and combined with different structures of various ship spaces, which is conducive to promotion and use.
[0059] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and substitutions can be made without departing from the technical principles of the present invention. These improvements and substitutions should also be regarded as the scope of protection of the present invention.
