Description

Technical Field

[0001] The utility model relates to the technical field of air pipe heads, in particular to an air pipe head for ships. Background Art

[0002] The air pipe head is an important part of the vent pipe, ensuring that the vent pipe works normally and maintaining air circulation in the cabin. The air pipe head is generally installed at the top of the vent pipe, and through the diversion function and protection function, it keeps the vent pipe unobstructed and prevents water from entering the cabin.

[0003] However, in the prior art, the existing air pipe heads are usually unable to deliver gas according to the internal air pressure, and when water accumulates inside the pipe head, it cannot be discharged, thereby affecting the delivery of gas. Utility Model Content

[0004] In view of the above-mentioned problems existing in the prior art, the main purpose of the utility model is to provide an air pipe head for ships, which solves the problem that the air pipe head in the prior art usually cannot transport according to the internal air pressure, and when water accumulates inside the pipe head, it cannot be discharged, thereby affecting the transportation of gas.

[0005] The technical solution of the utility model is as follows: an air pipe head for ships, comprising a pipe, a conical cover fixedly connected to the inside of the pipe, a fixing plate fixedly connected to the bottom of the conical cover, a connecting rod fixedly connected to the bottom of the fixing plate at equal intervals, a bottom plate fixedly connected between the bottoms of a plurality of connecting rods, an exhaust pipe slidably connected to the bottom of the fixing plate and located between the connecting rods, the top of the exhaust pipe extends to the top of the fixing plate, a first limiting plate fixedly connected to the bottom of the exhaust pipe, a first sliding rod fixedly connected between the first limiting plate and the bottom plate, a first spring fixedly connected between the bottom of the first limiting plate and the bottom plate and located on the outside of the first sliding rod, the top of the first sliding rod extends to the inside of the exhaust pipe, exhaust holes are opened at equal intervals on the outside of the exhaust pipe, and a second limiting plate is fixedly connected to the outside of the exhaust pipe and located above the fixing plate.

[0006] Through the above technical solution, when conveying gas, the exhaust pipe can be moved downward by the size of the internal air pressure. When the air pressure is high, it will move a larger distance, so that the exhaust hole can discharge more gas. Similarly, when the air pressure is small, the discharged gas is smaller. Through the elasticity of the first spring, when there is no air pressure, external water is prevented from entering. The exhaust pipe can be limited by the second limiting plate. Similarly, the first limiting plate can also be limited. Through the conical cover, the leaked water can be collected into the inside of the discharge pipe and discharged by air pressure.

[0007] As a preferred embodiment, a second connecting pipe is fixedly connected to the top of the pipeline, the second connecting pipe is communicated with the pipeline, an arc-shaped cover is fixedly connected to the interior of the second connecting pipe, a connecting plate is fixedly connected to the interior of the second connecting pipe and above the arc-shaped cover, a slider is fixedly connected to the top of the connecting plate, a second sliding rod is slidably connected to the bottom of the slider, and the bottom of the second sliding rod extends to the bottom of the arc-shaped cover and is fixedly connected to a rubber ball.

[0008] Through the above technical solution, the rubber ball and the arc cover cooperate with each other, so that the sealing effect can be increased and the backflow of water can be avoided.

[0009] As a preferred embodiment, first connecting pipes are fixedly connected to the outside of the pipeline at equal intervals, the first connecting pipes are communicated with the inside of the pipeline, and the inside of the first connecting pipes is fixedly connected to a filter screen.

[0010] Through the above technical solution, the filter screen is used to prevent foreign matter from entering.

[0011] As a preferred implementation, the top of the second slide bar passes through the slider and is fixedly connected to a limiting block, and a second spring is fixedly connected between the limiting block and the slider and located on the outside of the second slide bar.

[0012] Through the above technical solution, due to the elasticity of the second spring, the rubber ball is separated from the arc cover when there is air pressure, and the rubber ball is attached to the arc cover when there is no air pressure.

[0013] As a preferred implementation, a sealing ring is fixedly connected to the bottom of the arc-shaped cover.

[0014] Through the above technical solution, the sealing effect is enhanced through the sealing ring.

[0015] As a preferred implementation, one end of the first connecting pipe and one end of the second connecting pipe are both fixedly connected with a flange.

[0016] Through the above technical solution, it is convenient to connect with external pipelines through flanges.

[0017] Compared with the prior art, the advantages and positive effects of the utility model are:

[0018] In the utility model, when conveying gas, the exhaust pipe can be moved downward by the internal air pressure. When the air pressure is high, the moving distance is large, so that the exhaust hole can discharge more gas. Similarly, the gas discharged when the air pressure is low is small. The elasticity of the first spring can prevent external water from entering when there is no air pressure. The exhaust pipe can be limited by the second limiting plate. Similarly, the first limiting plate can also be limited. The leaked water can be collected into the interior of the discharge pipe by the conical cover and discharged by air pressure.

[0019] Through the cooperation of the rubber ball and the arc cover, the sealing effect can be enhanced to avoid the backflow of water. Through the elasticity of the second spring, the rubber ball can be separated from the arc cover when there is air pressure, and when there is no air pressure, the rubber ball can fit the arc cover and pass through the sealing ring, thereby enhancing the sealing effect.

[0028] In this embodiment, when conveying gas, the exhaust pipe 8 can move downward by the size of the internal air pressure. When the air pressure is high, it will move a larger distance, so that the exhaust hole 9 can discharge more gas. Similarly, when the air pressure is small, the discharged gas is smaller. Through the elasticity of the first spring 11, when there is no air pressure, external water is prevented from entering. The exhaust pipe 8 can be limited by the second limiting plate 10. Similarly, the first limiting plate 7 can also be limited. Through the conical cover 2, the leaked water can be collected into the inside of the discharge pipe 8 and discharged by air pressure.

[0029] like Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, a second connecting pipe 23 is fixedly connected to the top of the pipeline 1, the second connecting pipe 23 is communicated with the pipeline 1, the interior of the second connecting pipe 23 is fixedly connected to the arc cover 14, a connecting plate 15 is fixedly connected to the interior of the second connecting pipe 23 and located above the arc cover 14, a slider 16 is fixedly connected to the top of the connecting plate 15, a second slide rod 17 is slidably connected to the bottom of the slider 16, and the bottom of the second slide rod 17 extends to the bottom of the arc cover 14 and is fixedly connected to a rubber ball 20.

[0030] In this embodiment, the rubber ball 20 cooperates with the arc cover 14, so that the sealing effect can be enhanced and the backflow of water can be avoided.

[0031] like Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, first connecting pipes 12 are fixedly connected to the outside of the pipeline 1 at equal intervals, the first connecting pipes 12 are communicated with the inside of the pipeline 1, and the inside of the first connecting pipes 12 is fixedly connected with a filter screen 13.

[0032] In this embodiment, the filter screen 13 is used to prevent foreign matter from entering.

[0033] like Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, the top of the second slide bar 17 passes through the slider 16 and is fixedly connected to the limiting block 18 , and a second spring 19 is fixedly connected between the limiting block 18 and the slider 16 and located on the outside of the second slide bar 17 .

[0034] In this embodiment, due to the elasticity of the second spring 19, the rubber ball 20 is separated from the arc cover 14 when there is air pressure, and the rubber ball 20 is attached to the arc cover 14 when there is no air pressure.

[0038] In this embodiment, the flange 22 is used to facilitate connection with external pipelines.

[0039] Working principle:

[0040] like Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, when conveying gas, the exhaust pipe 8 can move downward by the internal air pressure. When the air pressure is high, the moving distance is large, so that the exhaust hole 9 can discharge more gas. Similarly, when the air pressure is small, the discharged gas is small. The elasticity of the first spring 11 can prevent external water from entering when there is no air pressure. The exhaust pipe 8 can be limited by the second limiting plate 10. Similarly, the first limiting plate 7 can also be limited. Through the conical cover 2, the leaked water can be collected into the inside of the discharge pipe 8 and discharged by air pressure.

[0041] Through the cooperation between the rubber ball 20 and the arc cover 14, the sealing effect can be increased to avoid the backflow of water. Through the elasticity of the second spring 19, when there is air pressure, the rubber ball 20 is separated from the arc cover 14. When there is no air pressure, the rubber ball 20 is attached to the arc cover 14 through the sealing ring 21, thereby increasing the sealing effect.
