DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0025] By those skilled in the art, the components in this case are connected in sequence. The specific connection and operation sequence should refer to the following working principle. The detailed connection means are well-known technologies in the art. The following mainly introduces the working principle and process.

[0026] Depend on Figure 1 , Figure 2 , Figure 4 and Figure 5 It can be seen that a marine ventilator device for preventing seawater from entering in this case includes a main pipe 1, a sub-pipe 2 is inserted under the inner wall of the main pipe 1, a fan 3 is connected to the bottom of the sub-pipe 2, and a collecting device is arranged inside the main pipe 1; the collecting device includes a top cover 6, a collecting plate 7, a first connecting pipe 8, a first guide hole 9, a first sleeve 10, a through hole 11, a dispersion plate 12 and a bottom cover 14; the top cover 6 is fixedly connected to the inner wall of the main pipe 1, a collecting plate 7 is arranged under the top cover 6, a first connecting pipe 8 is arranged above the collecting plate 7, the top of the first connecting pipe 8 is connected to the first guide hole 9 opened on the surface of the top cover 6, the bottom of the first connecting pipe 8 is connected to the first sleeve 10, the first sleeve 10 penetrates the collecting plate 7 through the through hole 11 opened in the collecting plate 7, the outer wall of the first sleeve 10 is fixedly connected to the dispersion plate 12 located below the collecting plate 7, the bottom cover 14 is arranged under the first sleeve 10, and the outer wall of the bottom cover 14 is fixedly connected to the outer wall of the main pipe 1.

[0027] In the specific implementation process, it is worth pointing out that the main pipe 1 and the auxiliary pipe 2 cooperate to achieve height adjustment, which is conducive to installation at different positions of the ship. For example, if it is installed at a low place close to the water surface of the ship, the main pipe 1 can be extended upward along the outer wall of the auxiliary pipe 2, and the overall height can be adjusted as high as possible, so as to avoid water directly entering from the top of the main pipe 1 due to wind and waves. When installed at a high place far from the water surface of the ship, the main pipe 1 can be adjusted downward to increase the length of the plug-in position of the main pipe 1 and the auxiliary pipe 2, which is conducive to improving the overall strength. The fan 3 is a duct fan, and the specific model is not limited, as long as it meets the use requirements. Through the fan 3, the speed of air intake or ventilation can be accelerated, which is conducive to airflow. The top cover 6 is convex as a whole, and a hole structure is opened in the center. In this way, when rainwater, river water or seawater flows into the main pipe 1, most of the water is intercepted by the top cover 6 between the top cover 6 and the main pipe 1, and enters the first sleeve 10 through the first guide hole 9 and the first connecting pipe 8. Some of the water that passes through the hole structure on the surface of the top cover 6 is collected by the collecting plate 7, which is concave, and flows down through the through holes 11 on the surface of the collecting plate 7. After being blocked and guided by the dispersion plate 12, this part of the water is prevented from entering the interior of the auxiliary pipe 2 through the hole structure on the surface of the bottom cover 14. The dispersion plate 12 guides this part of the water to the top of the bottom cover 14. Since the bottom cover 14 and the top cover 6 have the same shape and specifications, this part of the water will stay on the top of the bottom cover 14, that is, the annular area surrounded by the bottom cover 14 and the inner wall of the main pipe 1, so as to realize water collection without affecting the air flow.

[0028] In one practicable manner, see Figure 1 , Figure 2 , Figure 4 and Figure 5 A flow guide device is provided below the first sleeve 10; the flow guide device includes a first drainage duct 13, a second drainage hole 15, a second connecting pipe 16, a second sleeve 17, a second drainage duct 18 and a hose 19; one end of the first drainage duct 13 is connected to the lower side of the first sleeve 10, the end of the first drainage duct 13 extends to the second drainage hole 15 opened on the surface of the bottom cover 14, the bottom of the second drainage hole 15 is connected to the second connecting pipe 16 fixed to the lower side of the bottom cover 14, the bottom of the second connecting pipe 16 is connected to the second sleeve 17, the lower side of the second sleeve 17 is connected to the second drainage duct 18, the end of the second drainage duct 18 is connected to the hose 19, and the end of the hose 19 passes through the side wall of the auxiliary pipe 2.

[0029] In the specific implementation process, it is worth pointing out that since rainwater is collected on the top of the first sleeve 10 and the bottom cover 14, for a long time, due to the rise of the liquid level and the shaking of the ship, water will inevitably flow into the inside of the auxiliary pipe 2 and into the fan 3 and the inside of the ship. Therefore, through the cooperation between the first drainage pipe 13 and the second guide hole 15, the accumulated water inside the first sleeve 10 can be led out to the second connecting pipe 16 at the bottom of the bottom cover 14 and collected by the second sleeve 17, and the water at the top of the bottom cover 14 will directly enter the second connecting pipe 16 through the second guide hole 15 and be collected by the second sleeve 17. At this point, the second sleeve 17 completes the collection of all the accumulated water inside the main pipe 1, and then The water is discharged to the outside of the auxiliary pipe 2 through the second drainage duct 18 and the hose 19, so that the water entering the main pipe 1 cannot flow into the auxiliary pipe 2. Of course, in order to improve the diversion effect of the water entering the main pipe 1 and ensure that all the water can be effectively collected and discharged, multiple sets of collecting devices can be installed in sequence inside the main pipe 1. Of course, the collecting device located above can ensure that the water entering the main pipe 1 will not enter the auxiliary pipe 2 after multiple collections, and the air can enter the auxiliary pipe 2 normally through the main pipe 1, the hole structure in the center of the top cover 6 and the hole structure on the top of the bottom cover 14. Due to the design of the fan 3, the air circulation speed can be accelerated, which is conducive to the entry of fresh air into the ship.

[0030] In one practicable manner, see Figure 5 and Figure 8 The inner wall of the through hole 11 is fixedly connected to the outer wall of the first sleeve 10 through a support rod 37.

[0031] In the specific implementation process, it is worth pointing out that the support rod 37 and the collecting tray 7 are integrally formed and can be fixed to the outer wall of the first sleeve 10 by welding.

[0032] In one practicable manner, see Figure 1 , Figure 3 and Figure 6 A protective cap 20 is provided on the top of the main pipe 1, and a filter screen 21 is fixedly connected to the inner wall of the protective cap 20.

[0033] In the specific implementation process, it is worth pointing out that the protective cap 20 is arranged as a whole above the main pipe 1, which can prevent rainwater from directly pouring into the main pipe 1 during thunderstorms. Only when the wind and waves are strong, river water or sea water will enter a part of the inner part of the protective cap 20 in the form of waves, which greatly reduces the probability and amount of water entering the main pipe 1. Of course, the specific material and mesh number of the filter 21 are not limited, and it is sufficient to meet the use requirements. Its purpose is to prevent larger particles, birds, etc. from entering the interior of the main pipe 1, and ensure the smoothness and cleanliness of the interior of the main pipe 1.

[0034] Furthermore, a baffle 22 is provided inside the protective cap 20, and a sealing gasket 23 is fixedly connected to the side of the baffle 22 close to the main pipe 1. The baffle 22 is fixedly connected to the inner wall of the protective cap 20 through a connecting rod 25. A limiting rod 24 is fixedly connected to the surface of the connecting rod 25. The outer wall of the limiting rod 24 is sleeved with a limiting ring 27 fixed to the outer wall of the main pipe 1.

[0035] In the specific implementation process, it is worth pointing out that the purpose of setting the baffle 22 and the sealing gasket 23 is that when the wind and waves are strong, too much rainwater enters the main pipe 1, or the outdoor air is seriously polluted, the baffle 22 can be covered on the top of the main pipe 1 to achieve the closure of the main pipe 1, wherein the sealing gasket 23 can be made of rubber material to improve the sealing effect of the baffle 22 on the main pipe 1, wherein the connecting rod 25 can fix the limiting rod 24 and facilitate the installation of the baffle 22. Through the cooperation between the limiting ring 27 and the limiting rod 24, the parallelism of the baffle 22 and the top of the main pipe 1 is guaranteed to ensure a tight fit.

[0036] Furthermore, a driving device is provided below the protective cap 20; the driving device comprises a screw 26, a retaining ring 28, a reserved hole 29, a nut 30, a sleeve 31, a telescopic rod 32 and a base 33; the retaining ring 28 is sleeved on the outer wall of the main pipe 1, a reserved hole 29 is provided on the surface of the retaining ring 28, a screw 26 fixed to the end of the limiting rod 24 is inserted into the inner wall of the reserved hole 29, a nut 30 located below the retaining ring 28 is threadedly connected to the outer wall of the screw 26, a sleeve 31 is fixedly connected to the bottom of the retaining ring 28, the inner wall of the sleeve 31 is movably connected to the outer wall of the main pipe 1, a telescopic rod 32 is fixedly connected to the bottom of the retaining ring 28, a base 33 is fixedly connected to the bottom of the telescopic rod 32, and one side of the base 33 is fixedly connected to the outer wall of the main pipe 1.

[0037] During the specific implementation process, it is worth pointing out that the design purpose of the screw 26 and the nut 30 is to fix the limit rod 24 and the retaining ring 28, so as to facilitate the assembly of the protective cap 20 on the top of the main pipe 1. The height of the sleeve 31 is relatively high and is installed at the bottom of the retaining ring 28, which is beneficial to the stability between the retaining ring 28 and the main pipe 1. The telescopic rod 32 can adopt a telescopic motor, a hydraulic cylinder and other structures. The specific model and specification are not limited as long as the use requirements are met. The purpose of its setting is to remotely control the retaining ring 28 to rise and fall along the outer wall of the main pipe 1, which is beneficial to control the height of the protective cap 20 and control whether the baffle 22 closes the top of the main pipe 1.

[0038] In one practicable manner, see Figure 1 and Figure 2 The bottom of the auxiliary pipe 2 is connected to a fixed pipe 4.

[0039] In the specific implementation process, it is worth pointing out that the bottom of the fixed pipe 4 is set to the specification and shape connected to the ship's fresh air duct according to actual needs to meet the connection requirements.

[0040] In one practicable manner, see Figure 7 A sealing tube 5 is fixedly connected to the lower part of the inner wall of the main tube 1 , and the inner wall of the sealing tube 5 is in contact with the outer wall of the auxiliary tube 2 .

[0041] In the specific implementation process, it is worth pointing out that the sealing tube 5 can be made of rubber material, which is conducive to improving the sealing between the main tube 1 and the auxiliary tube 2 to avoid air leakage, water ingress, etc.

[0042] In one practicable manner, see Figure 1 , Figure 2 and Figure 7 An opening 34 is provided on the surface of the main pipe 1 , and a plurality of fixed ports 35 are connected to one side of the opening 34 at equal distances from top to bottom. A positioning rod 36 is fixedly connected to the outer wall of the auxiliary pipe 2 .

[0043] In the specific implementation process, it is worth pointing out that the opening 34 is vertically arranged to facilitate the insertion of the auxiliary pipe 2 equipped with the positioning rod 36 into the interior of the main pipe 1. According to the required height of the main pipe 1, the corresponding fixing port 35 is selected, and the positioning rod 36 is aligned with the fixing port 35 and then the main pipe 1 is rotated to adjust the positioning rod 36 to the interior of the fixing port 35. Then, under the action of gravity, the main pipe 1 falls, so that the fixing port 35 and the positioning rod 36 are clamped together, thereby achieving height fixation of the main pipe 1 and the auxiliary pipe 2.

[0044] Working principle: the bottom of the fixed pipe 4 is set to the specification and shape connected to the ship's fresh air duct according to actual needs, and is connected to the ship's fresh air duct. Then, the auxiliary pipe 2 is inserted into the inside of the main pipe 1. According to the required height of the main pipe 1, the corresponding fixing port 35 is selected, and the positioning rod 36 is aligned with the fixing port 35 and then the main pipe 1 is rotated, and the positioning rod 36 is adjusted to the inside of the fixing port 35. Then, under the action of gravity, the main pipe 1 falls, so that the fixing port 35 and the positioning rod 36 are clamped together to achieve the height fixation of the main pipe 1 and the auxiliary pipe 2. Then, the limiting rod 24 is passed through the corresponding limiting ring 27, and the screw 26 at the bottom of the limiting rod 24 is passed through the reserved hole 29, and the limiting rod 24 is fixed by the nut 30. The rod 24 and the retaining ring 28 are fixed, and the height of the telescopic rod 32 is controlled according to the demand to determine whether the baffle 22 closes the top of the main pipe 1. When the baffle 22 does not close the top of the main pipe 1, in windy and choppy weather, after part of the water flows into the main pipe 1 through the protective cap 20, most of the water is intercepted by the top cover 6 between the top cover 6 and the main pipe 1, and enters the first sleeve 10 through the first guide hole 9 and the first connecting pipe 8. Part of the water that passes through the hole structure on the surface of the top cover 6 is collected by the collecting plate 7, which is concave, and flows down through the through hole 11 on the surface of the collecting plate 7, and is blocked and guided by the dispersion plate 12 to prevent this part of the water from entering the interior of the auxiliary pipe 2 through the hole structure on the surface of the bottom cover 14, and the dispersion plate 12 is used to prevent the water from entering the interior of the auxiliary pipe 2 through the hole structure on the surface of the bottom cover 14. The plate 12 guides this part of water to the top of the bottom cover 14. Since the bottom cover 14 and the top cover 6 have the same shape and specifications, this part of water will stay on the top of the bottom cover 14, that is, the annular area surrounded by the bottom cover 14 and the inner wall of the main pipe 1, so as to collect water without affecting the airflow. At this time, the cooperation between the first drainage pipe 13 and the second guide hole 15 can guide the accumulated water inside the first sleeve 10 to the second connecting pipe 16 at the bottom of the bottom cover 14 and be collected by the second sleeve 17, while the water at the top of the bottom cover 14 will directly enter the second connecting pipe 16 through the second guide hole 15 and be collected by the second sleeve 17. At this point, the second sleeve 17 completes the collection of all the accumulated water inside the main pipe 1, and then The water is discharged to the outside of the auxiliary pipe 2 through the second drainage duct 18 and the hose 19, so that the water entering the main pipe 1 cannot flow into the auxiliary pipe 2. Of course, in order to improve the diversion effect of the water entering the main pipe 1 and ensure that all the water can be effectively collected and discharged, multiple sets of collecting devices can be installed in sequence inside the main pipe 1. Of course, the collecting device located above can ensure that the water entering the main pipe 1 will not enter the auxiliary pipe 2 after multiple collections, and the air can enter the auxiliary pipe 2 normally through the main pipe 1, the hole structure in the center of the top cover 6 and the hole structure on the top of the bottom cover 14. Due to the design of the fan 3, the air circulation speed can be accelerated, which is conducive to the entry or exhaust of fresh air inside the ship.
