Description

Technical Field

[0001] The invention belongs to the technical field of ship ventilation ducts, and more specifically, relates to a ship ventilation duct water-flooding prevention device. Background Art

[0002] In the working environment of ships, ventilation and flooding prevention are often conflicting requirements. In humid or harsh environments, ships need good ventilation to prevent internal humidity accumulation, but they also need to prevent seawater or other liquids from entering the ship. Traditional ship ventilation systems usually use direct ventilation methods, opening vents or using fans to allow fresh air to enter the ship through pipes. Therefore, the outer end of the pipe will be located outside the ship, and the exposed pipe is prone to flooding.

[0003] In the prior art, there is a technology named "Anti-flooding ventilation device for ship ventilation" and the publication (announcement) number is "CN117775255A". The technology is used for the anti-flooding ventilation device for ship ventilation, which belongs to the field of ship ventilation technology. In the present invention, a first water-absorbing sponge net and a second water-absorbing sponge net are respectively arranged on both sides of the middle partition block, and a control mechanism is arranged at the lower ends of the first water-absorbing sponge net and the second water-absorbing sponge net. The first water-absorbing sponge net is fixedly connected to the first pressure plate at one end close to the middle partition block, and the second water-absorbing sponge net is fixedly connected to the first pressure plate at one end close to the middle partition block. One end of the partition block is fixedly connected to a second pressing plate, a first collecting box is provided at the lower side of the end of the first absorbent cotton net away from the middle partition block, and a second collecting box is provided at the lower side of the end of the second absorbent cotton net away from the middle partition block. The protective plate can isolate most of the seawater poured directly, so that only a small amount of seawater is poured in, and water vapor in the air enters the air inlet frame. When a small amount of seawater and water vapor in the air enter the air inlet frame, they will be absorbed by the first absorbent cotton net and the second absorbent cotton net, effectively preventing seawater from pouring in and water vapor from entering. However, this technology does not involve the technical problems and technical solutions of the present application. Summary of the invention

[0004] The technical problem to be solved by the present invention is: in view of the deficiencies in the prior art, a ship ventilation duct anti-flooding device is provided, which can realize reliable ventilation, prevent rainwater and waves from entering the duct body, and prevent the water level below from rising and pouring into the duct body, thereby ensuring the safety of the ship.

DETAILED DESCRIPTION

[0023] The following is a further detailed description of the specific implementation of the present invention, such as the shape, structure, mutual position and connection relationship between the various components involved, the function and working principle of each part, etc., through the description of the embodiments with reference to the accompanying drawings:

[0024] As attached Figure 1 -Attached Figure 4As shown, the present invention is a device for preventing flooding of a ship ventilation duct, wherein a support plate 120 is arranged on the outer wall of a duct body 110 of the ventilation duct 100, a hinge seat 130 is arranged on the top side wall of the duct body 110, a shell 210 of a protective shell 200 is arranged on the support plate 120 at the bottom, a vent 220 is arranged on the bottom of the side wall of the shell 210, a lever 310 of a floating closure 300 is rotatably connected to the hinge seat 130, a floating ball 320 is arranged on the lower end of the lever 310, and a flip cover 330 is arranged on the upper end of the lever 310. The above structure proposes an improved technical solution to address the deficiencies in the prior art. When the structure is set, a ventilation duct 100, a protective shell 200 and a floating closure 300 are respectively set. The ventilation duct 100 is used to realize internal and external ventilation. The protective shell 200 is used to protect the duct body 100. The floating closure 300 is used to close the duct body 110 when the water level rises, and to open the duct body 110 when the water level drops. The outer wall of the duct body 110 of the ventilation duct 100 is provided with a support plate 120, and the support plate 120 is sleeved on the outer ring of the duct body 110. The two are fixedly connected. The top side wall of the duct body 110 is provided with a support plate 120. The hinge seat 130 is used to connect the lever 310. The bottom of the shell 210 of the protective shell 200 is set on the support plate 120 to achieve a fixed connection between the protective shell 200 and the support plate 120. A vent 220 is opened at the bottom of the side wall of the shell 210, and the vent 220 is used for air intake. The lever 310 of the floating closure 300 is rotatably connected to the hinge seat 130. A float 320 is set at the lower end of the lever 310, and a flip cover 330 is set at the upper end of the lever 310. The lever 310 can be flipped in different directions relative to the pipe body 110. When the device is used, the pipe body 110 is ventilated, and the shell 210 is ventilated and breathable through the vent 220. The shell 210 is sealed and shielded from the top of the pipe body 110 to prevent rainwater from falling from above and waves from pouring into the pipe body 110. When the amount of water below the ventilation pipe 100 gathers and rises, water pours into the protective shell 200 through the vent 220 of the protective shell 200. The rising water level causes the float 320 to float up, and the floating of the float 320 drives the flip cover 330 to flip until the flip cover 330 fits the top opening of the pipe body 110 to achieve the closure of the top opening, preventing the rising water level from pouring into the pipe 110, and reliably playing the role of preventing water from pouring into the pipe, protecting the safety of the ship. The ship ventilation pipe anti-flooding device described in the present invention can not only achieve reliable ventilation, but also prevent rainwater and waves from entering the pipe body, and can also prevent the water level from rising below from pouring into the pipe body, thereby ensuring the safety of the ship.

[0025] The vents 220 are provided in plurality, and the plurality of vents 220 are distributed at the bottom of the side wall of the housing 210, and the height of the vents 220 is lower than the top opening of the pipe body 110. In the above structure, the housing 210 is ventilated and breathable through the vents 220, and the height of the vents 220 is lower than the top opening of the pipe body 110, so that the float can be pushed up when the water level entering the housing rises. If the height of the vents 220 is higher than the top opening of the pipe body 110, the water entering will directly enter the pipe body 110, and it will not be able to prevent water from entering due to the rising water level.

[0026] The housing 210 includes a top plate 230, a first side plate 240, a second side plate 250, and a rear plate 260, and the top opening of the pipe body 110 is located below the top plate 230. In the above structure, the top plate 230, the first side plate 240, the second side plate 250, and the rear plate 260 are fixedly connected to form an integral structure, and the lower ends of the first side plate 240, the second side plate 250, and the rear plate 260 are fixedly connected to the support plate. In this way, the top plate is located above the pipe body, and the top opening can be reliably shielded.

[0027] A sealing gasket is disposed on the lower surface of the flip cover 330 of the floating closure 300. The above structure improves the sealing effect when the float floats up and the flip cover fits the top opening of the pipeline body 110.

[0028] The shell 210 of the protective shell 200 is made of transparent material, and the bottom of the shell 210 is screwed and fixed on the support plate 120. In the above structure, the protective shell can be made of transparent plastic material. In this way, the water level inside the shell 210 can be observed at any time.

[0029] The filter screen is installed at the position of the ventilation opening 220. In order to prevent external debris from entering during ventilation, the ventilation opening 220 is provided with a detachable filter screen to filter the incoming airflow.

[0030] The ventilation pipe 100 includes a pipe body 110, a support plate 120 and a hinge seat 130, the protective shell 200 includes a shell 210 and a vent 220, and the floating closure 300 includes a lever 310, a float 320 and a flap 330. The lever 310 and the flap 330 of the floating closure 300 are in an obtuse angle structure. In the above structure, the pipe body 110 serves as a ventilation channel of the ship, and ventilation is performed through the pipe 110. The shell 210 is ventilated through the vent 220, and the shell 210 closes and shields the top of the pipe 110 through the top plate 230 to prevent rainwater falling from above and waves from pouring into the pipe body 110. When the floating closure 300 is in a natural state, the sum of the gravity of the float 320 and the lever 310 is greater than the gravity of the flap 330. Under the gravity of the float 320 and the lever 310, the flap 330 flips upward without affecting the normal ventilation of the pipe body 110. When the water volume under the ventilation pipe 100 accumulates and rises, the water flows into the protective shell 200 through the vent 220 of the protective shell 200. The rising water level makes the float 320 float up, and the flap 330 flips downward to close the opening at the top of the pipe body 110, achieving a closed and waterproof effect. After the flap 330 closes the top opening of the pipe body 110, since the water submerges the pipe body 100, the water pressure exerts force on the outer surface of the flap 330, ensuring that the flap 330 is closed reliably.

[0031] The lever 310, the float 320 and the flip cover 330 of the floating closure 300 are all made of hollow light plastic material. In the above structure, since the buoyancy of water is limited, the lever 310, the float 320 and the flip cover 330 are all made of hollow light material to facilitate floating.

[0032] The ship ventilation duct anti-flooding device of the present invention is provided with a ventilation duct 100, a protective shell 200 and a floating sealing member 300 during structural setting. The ventilation duct 100 is used to realize internal and external ventilation. The protective shell 200 is used to protect the duct body 100. The floating sealing member 300 is used to close the duct body 110 when the water level rises and to open the duct body 110 when the water level drops. The outer wall of the duct body 110 of the ventilation duct 100 is provided with a support plate 120. The support plate 120 is sleeved on the outer ring of the duct body 110. The two are fixedly connected. A hinge seat 130 is arranged on the top side wall of 110, and the hinge seat 130 is used to connect the lever 310. The bottom of the shell 210 of the protective shell 200 is arranged on the support plate 120 to realize the fixed connection between the protective shell 200 and the support plate 120. A vent 220 is arranged on the bottom of the side wall of the shell 210, and the vent 220 is used for air intake. The lever 310 of the floating closure 300 is rotatably connected to the hinge seat 130, a float 320 is arranged at the lower end of the lever 310, and a flip cover 330 is arranged at the upper end of the lever 310. The lever 310 can be flipped in different directions relative to the pipe body 110. When the device is in use, the pipe body 110 is ventilated, and the shell 210 is ventilated and breathable through the vent 220. The shell 210 closes and shields the pipe body 110 from above to prevent rainwater falling from above and waves from pouring into the pipe body 110. When the amount of water below the ventilation pipe 100 accumulates and rises, the water pours into the protective shell 200 through the vent 220 of the protective shell 200. The rising water level causes the float 320 to float up, and the floating of the float 320 drives the flip cover 330 to flip over until the flip cover 330 fits the top opening of the pipe body 110, thereby closing the top opening and preventing the rising water level from pouring into the pipe 110. This reliably prevents water from flooding and protects the safety of the ship.

[0033] The present invention is described above by way of example in conjunction with the accompanying drawings. It is obvious that the specific implementation of the present invention is not limited to the above-mentioned method. As long as various improvements are made using the method concept and technical solution of the present invention, or the concept and technical solution of the present invention are directly applied to other occasions without improvement, they are all within the protection scope of the present invention.
