A shipboard indoor ventilation device

Abstract

This invention discloses a shipboard indoor ventilation device, comprising: louvers for opening or closing ventilation; and a demister disposed on the inner side of the louvers, including a demister frame, within which a demister section and a water-collecting section are disposed. The demister section intercepts water mist in the air, and the water-collecting section is disposed on the side of the demister facing away from the louvers, for collecting water dripping from the demister section and guiding the water out. By disposing of the demister on the inner side of the louvers, air carrying water mist must pass through the demister section before entering the cabin. The demister effectively removes water mist from the air, thus preventing indoor water accumulation caused by water-mist-laden air directly entering the cabin. Water intercepted on the demister section collects and forms droplets, which are then collected and discharged through the water-collecting section, preventing water from the demister from flowing directly into the cabin and causing indoor water accumulation.

Description

Technical Field

[0001] This application relates to the field of marine application technology, and in particular to a marine indoor ventilation device. Background Technology

[0002] Ventilation systems, as a crucial component of ships, facilitate air exchange with the outside environment, ensuring the safety of personnel within cabins. They also serve to dissipate heat from equipment, introduce fresh air, and remove exhaust fumes and toxic gases. Ventilation terminals typically utilize louvers or ventilation ducts; regardless of the type, they must be closable, a requirement mandated by fire safety regulations.

[0003] Because ships operate in harsh environments at sea, when the wind and waves are large, seawater can easily enter the cabin through the gaps between the louver blades, and rainwater on the windward side can also easily enter the cabin through the gaps between the louver blades. Especially when the louvers are installed at an angle, the air intake gaps between the blades tend to be more horizontal, making it easier for seawater and rainwater to enter the cabin laterally, leading to water accumulation inside. Summary of the Invention

[0004] The purpose of this invention is to provide a shipboard indoor ventilation device that can solve the above-mentioned problems existing in the prior art.

[0005] To achieve the above objectives, this application adopts the following technical solution:

[0007] Venetian blinds are used to open or close for ventilation;

[0008] A demister is disposed on the inner side of the louver and includes a demister frame. The demister frame is provided with a demister section and a water receiving section. The demister section is used to intercept water mist in the air. The water receiving section is disposed on the side of the demister away from the louver and is used to receive water dripping from the demister section and guide the water out.

[0009] Optionally, the demisting section includes a plurality of baffles arranged in parallel at intervals; the water receiving section includes a water collecting pipe and a plurality of water receiving plates, the plurality of water receiving plates being arranged in parallel at intervals, and the arrangement direction of the water receiving plates being parallel to the arrangement direction of the baffles, so that the water receiving plates can collect the water dripping from the baffles; the water collecting pipe connects all the water receiving plates, and the water on the water receiving plates is collected through the water collecting pipe and guided out.

[0010] Optionally, a water receiving pipe is provided on the side of the water receiving plate away from the demisting part, and a first water inlet groove is provided on the side of the water receiving pipe near the water receiving plate. The first water inlet groove is located on the upper side of the water receiving plate. The water collecting pipe is connected to the water receiving pipe. The water from the water receiving plate is collected in the water receiving pipe after passing through the first water inlet groove, and then guided to the water collecting pipe through the water receiving pipe.

[0011] Optionally, a connector is installed at the end of the water inlet pipe, and the water collection pipe is connected to the connector to establish a connection between the water collection pipe and the water inlet pipe.

[0012] Optionally, the connector includes a connecting pipe section and a sleeve section that are perpendicularly connected to each other. The connecting pipe section is connected to the water receiving pipe, and the sleeve section is fitted onto the outside of the water collecting pipe to fix the water collecting pipe. The water collecting pipe is provided with a second water inlet groove on the side near the connecting pipe section, and water in the water receiving pipe can enter the water collecting pipe through the connecting pipe section and the second water inlet groove.

[0013] Optionally, the water receiving plate is rotatably installed inside the demister frame, and the connecting pipe is rotatably connected to the water receiving pipe.

[0014] Optionally, the connector further includes a tensioning member for tightening or loosening the water collection pipe, thereby adjusting or locking the sway angle of the water receiving plate based on the tensioning of the water collection pipe by the tensioning member.

[0015] Optionally, the tightening component includes a tightening nut and several circumferentially arranged grippers disposed at one end of the sleeve portion. The degree of compression of the grippers is adjusted by rotating the tightening nut, thereby adjusting the clamping degree of the grippers on the water collection pipe.

[0016] Optionally, along the arrangement direction of the water receiving plate, a retractable hose is connected between any two adjacent pipe connectors, and the retractable hose is sleeved outside the water collection pipe.

[0017] Optionally, the demister further includes a bottom water tray and a drain pipe connected to the bottom water tray. The bottom water tray is located at the bottom of the demister frame on the side facing away from the louvers. The bottom water tray collects water on the bottom frame of the demister frame and guides the water out.

[0018] The beneficial effects of this application are as follows: This invention provides a shipboard indoor ventilation device, including openable and closable louvers. When the ventilation is open, the tilted blades of the louvers can separate the incoming seawater or rainwater into several streams when facing waves or wind and rain, reducing the impact force of the waves or rainwater. A demister is installed on the inner side of the louvers. Before air carrying water mist enters the room through the louvers, it needs to pass through the demister's demisting section. The demister can remove water mist from the air to a large extent, thus avoiding the problem of indoor water accumulation caused by water mist-laden air directly entering the cabin. In addition, the inner side of the demister of this invention is also provided with a water receiving section for collecting dripping water from the demisting section. After the water intercepted on the demisting section gathers into water droplets, it can be collected and discharged through the water receiving section, preventing the water accumulated in the demister from flowing directly into the room and causing indoor water accumulation.

[0029] To make the technical problems solved by this application, the technical solutions adopted, and the technical effects achieved clearer, the technical solutions of the embodiments of this application are further described in detail below. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0030] In the description of this application, unless otherwise expressly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0031] In this application, unless otherwise expressly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature being directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature being directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0032] Because ships operate in harsh environments at sea, when the wind and waves are large, seawater can easily enter the cabin through the gaps between the louver blades, and rainwater on the windward side can also easily enter the cabin through the gaps between the louver blades. Especially when the louvers are installed at an angle, the air intake gaps between the blades tend to be more horizontal, making it easier for seawater and rainwater to enter the cabin laterally, leading to water accumulation inside.

[0033] To solve the above technical problems, such as Figure 1 As shown, this embodiment provides a shipboard indoor ventilation device 100, including:

[0034] Venetian blinds 1, used to open or close for ventilation;

[0035] The demister 2 is disposed inside the louver 1 and includes a demister frame 21. The demister frame 21 is provided with a demister part 22 and a water receiving part 23. The demister part 22 is used to intercept water mist in the air. The water receiving part 23 is disposed on the side of the demister 2 facing away from the louver 1 and is used to receive water dripping from the demister part 22 and guide the water out.

[0036] The louver 1 has several rotatable blades. By rotating all the blades, its opening and closing state can be changed. When it is open, there is a ventilation gap between adjacent blades, through which fresh outdoor air can enter the room. When it is closed, adjacent blades overlap each other, and outdoor and indoor air are separated.

[0037] The demister 2's demister section 22 has multiple alternating baffles. When air passes through the gaps between the baffles, water mist in the air continuously collides with the walls of the baffles, condensing into large water droplets that then drip off under gravity. Figure 2 In some cases, the ship's indoor ventilation system is installed at an angle, and water dripping from the deflector plate will drip directly onto the indoor floor, leading to indoor water accumulation. To address this, this solution provides a water receiving part 23 on the side of the defogging unit 22 facing away from the louvers 1. When water droplets from the deflector plate drip onto the indoor side, they will be collected by the water receiving part 23 and guided out, thus avoiding the problem of indoor water accumulation.

[0038] In summary, the shipboard indoor ventilation device 100 of this embodiment includes an openable and closable louver 1. When the ventilation is open, the tilted blades of the louver 1 can separate the incoming seawater or rainwater into several streams when facing waves or wind and rain, reducing the impact force of the waves or rainwater. A demister 2 is installed on the inner side of the louver 1. Before air carrying water mist enters the room through the louver 1, it needs to be demisted by the demisting section 22 of the demister 2. The demisting of the demister 2 can remove water mist from the air to a large extent, thereby avoiding the problem of indoor water accumulation caused by water mist-laden air directly entering the cabin. In addition, the inner side of the demister 2 of this invention is also provided with a water receiving section 23 for receiving water droplets on the demisting section 22. After the water intercepted on the demisting section 22 gathers into water droplets, it can be collected and discharged through the water receiving section 23, preventing the water accumulated in the demister 2 from directly flowing into the room and causing indoor water accumulation.

[0039] Reference Figure 1In one embodiment, the demisting section 22 includes a plurality of baffles arranged in parallel at intervals; the water receiving section 23 includes a water collecting pipe 234 and a plurality of water receiving plates 231, the plurality of water receiving plates 231 being arranged in parallel at intervals, and the arrangement direction of the water receiving plates 231 being parallel to the arrangement direction of the baffles, so that the water receiving plates 231 can collect the water dripping from the baffles; the water collecting pipe 234 connects all the water receiving plates 231, and the water on the water receiving plates 231 is collected through the water collecting pipe 234 and guided out.

[0040] Several water-collecting plates 231 are arranged parallel to the arrangement direction of the baffle plate near the indoor side. The spaced water-collecting plates 231 do not obstruct airflow. Figure 1 Taking the tilted state as an example, each baffle plate has a corresponding water receiving plate 231 directly below it, which can catch dripping water droplets. That is, water droplets dripping from any baffle plate can be caught by the water receiving plate 231, collected into the water collection pipe 234 and discharged in a unified manner, thereby realizing the water receiving and drainage function of the demister 2.

[0041] Meanwhile, to prevent water from accumulating in the cavity of the baffle plate itself, drainage holes can be provided in the low-lying areas of the baffle plate. Water accumulating in the middle of the baffle plate can flow directly down through the drainage holes to the next baffle plate. Water accumulating on the next baffle plate can also flow down through the drainage holes, or flow to the water receiving plate 231 and be discharged by the water collection pipe 234.

[0042] To achieve the interception and collection of dripping water on the water plate 231, in one embodiment, referring to Figure 4 The water receiving plate 231 is provided with a water receiving pipe 232 on the side away from the demisting part 22. The water receiving pipe 232 is provided with a first water inlet groove 2321 on the side close to the water receiving plate 231, and the first water inlet groove 2321 is located on the upper side of the water receiving plate 231. The water collecting pipe 234 is connected to the water receiving pipe 232. The water from the water receiving plate 231 is collected in the water receiving pipe 232 after passing through the first water inlet groove 2321, and then guided to the water collecting pipe 234 through the water receiving pipe 232.

[0043] Specifically, when water droplets fall onto the water receiving plate 231, the droplets will flow along the inclined surface of the water receiving plate 231 toward the side where the water receiving pipe 232 is located, until they are collected in the water receiving pipe 232. At this point, the water collection pipe 234 can be directly connected to the water receiving pipe 232 to drain the water accumulated in the water receiving pipe 232.

[0044] Preferably, the cross-section of the water inlet pipe 232 is an arc shape with a radius greater than 270°, ensuring that water in the water inlet pipe 232 does not easily overflow from the first water inlet channel 2321 when the water inlet plate 231 is tilted.

[0045] To achieve the connection between the water inlet pipe 232 and the water collection pipe 234, in one embodiment, a connector 233 is installed at the end of the water inlet pipe 232, and the water collection pipe 234 is connected to the connector 233, thereby establishing a connection between the water collection pipe 234 and the water inlet pipe 232 based on the connector 233.

[0046] Specifically, the connector 233 is connected and fixed to both the water inlet pipe 232 and the water collection pipe 234. At the same time, a through cavity is formed in the connector 233 to conduct water through the water inlet pipe 232 and the water collection pipe 234, thereby realizing the connection and locking of the water inlet pipe 232 and the water collection pipe 234 based on the connector 233, and simultaneously guiding the water in the water inlet pipe 232 to the water collection pipe 234.

[0047] Optionally, a connector 233 is provided on the same side of all water receiving plates 231, and a water collection pipe 234 is connected to all connectors 233 at the same time; or, two water collection pipes 234 are provided, and connectors 233 are provided on both sides of all water receiving plates 231, and all connectors 233 on the same side are connected by a water collection pipe 234.

[0048] Regarding the structure of connector 233, refer to... Figure 5-7 The connector 233 includes a connecting pipe portion 2331 and a sleeve portion 2332 that are perpendicularly connected to each other. The connecting pipe portion 2331 is connected to the water receiving pipe 232, and the sleeve portion 2332 is fitted onto the water collecting pipe 234 to fix the water collecting pipe 234. The water collecting pipe 234 is provided with a second water inlet groove 2341 on the side near the connecting pipe portion 2331, and water in the water receiving pipe 232 can enter the water collecting pipe 234 through the connecting pipe portion 2331 and the second water inlet groove 2341.

[0049] The connector 233 is connected to the water inlet pipe 232 via the connecting pipe section 2331. After the water collection pipe 234 passes through each sleeve section 2332, the second water inlet groove 2341 on one side of the water collection pipe 234 is aligned with the connecting pipe section 2331. Thus, the water in the water inlet pipe 232 can enter the water collection pipe 234 through the connecting pipe section 2331 and the second water inlet groove 2341, thereby achieving the purpose of collecting and discharging the water in the water inlet pipe 232.

[0050] The connector 233 uses the sleeve part 2332 to connect and fix the water collection pipe 234, which has the advantages of simple installation and good reliability.

[0051] In one embodiment, the water receiving plate 231 is rotatably installed inside the demister frame 21, and the connecting pipe 2331 is rotatably connected to the water receiving pipe 232.

[0052] The water receiving plate 231 is rotatably installed inside the demister frame 21. During use, the tilt angle of each water receiving plate 231 can be adjusted according to the tilt angle of the ship's indoor ventilation system 100, ensuring that the water receiving plate 231 can collect water dripping from all the baffles for the most effective and reliable drainage. Simultaneously, since the water collection pipe 234 cannot bend with the deflection of the water receiving plate 231, this design rotatably connects the connecting pipe portion 2331 of the connector 233 to the water receiving pipe 232. When the water receiving plate 231 is rotated, the connector 233 can be rotated accordingly to maintain the series connection between the water collection pipe 234 and all connectors 233.

[0053] In one embodiment, the connector 233 further includes a tensioning member 2333, which is used to tighten or loosen the water collection pipe 234. The tensioning member 2333 adjusts or locks the sway angle of the water receiving plate 231 based on the tightening or loosening of the water collection pipe 234.

[0054] Specifically, when it is necessary to adjust the sway angle of the water receiving plate 231, all the loosening and tightening components 2333 can be loosened first. At this time, the connector 233 can slide freely relative to the water collection pipe 234, so the water receiving plate 231 can be easily pushed to adjust the angle. After the angle adjustment is completed, tighten all the loosening and tightening components 2333. Due to the locking of the loosening and tightening components 2333, the water receiving plate 231 can no longer deflect relative to the water collection pipe 234, thus achieving the fixation of the water receiving plate 231.

[0055] Therefore, this solution provides a tensioning component 2333 in the connector 233, which satisfies the adjustment function of the water plate 231, and can lock the water plate 231 using the water collection pipe 234 and the connector 233, thus eliminating the need for a rotation adjustment and locking structure for the water plate 231.

[0056] Regarding the setting of tensioning component 2333, please refer to... Figure 6-7 The tensioning component 2333 includes a tensioning nut 23331 and several circumferentially arranged grippers 23332 disposed at one end of the sleeve portion 2332. The degree of compression of the grippers 23332 by rotating the tensioning nut 23331 is adjusted, thereby adjusting the clamping degree of the grippers 23332 on the water collection pipe 234.

[0057] Specifically, the tensioning component 2333 of this solution is similar to the existing conical sleeve structure. The jaws 23332 are in the shape of a contracting cone, and the tensioning nut 23331 has a corresponding conical inner cavity. The tensioning nut 23331 is threadedly connected to the sleeve part 2332. When the thread is screwed in, it can squeeze the jaws 23332 to contract and clamp the water collection pipe 234. When the thread is unscrewed, it can release the water collection pipe 234 by loosening the jaws 23332.

[0058] In one embodiment, along the arrangement direction of the water receiving plate 231, a retractable hose 2334 is connected between any two adjacent pipe connectors 233, and the retractable hose 2334 is sleeved on the outside of the water collection pipe 234.

[0059] Specifically, the side of the water collection pipe 234 is provided with a second water inlet groove 2341. To prevent water in the water collection pipe 234 from leaking out of the exposed area of ​​the second water inlet groove 2341, a retractable hose 2334 is provided between the connectors 233. The retractable hose 2334 can adapt to the expansion and contraction when the sway angle of the water receiving plate 231 is adjusted. At the same time, the water collection pipe 234 is completely wrapped inside the connectors 233 and the retractable hose 2334, which can prevent the second water inlet groove 2341 from being exposed and causing water to leak out of the pipe.

[0060] In one embodiment, the demister 2 further includes a bottom water tray 24 and a drain pipe connected to the bottom water tray 24. The bottom water tray 24 is located at the bottom of the side of the demister frame 21 facing away from the louver 1. The bottom water tray 24 collects water on the bottom frame of the demister frame 21 and guides the water out.

[0061] Specifically, based on the bottom water tray 24, water dripping onto the bottom frame of the demister frame 21 can be collected and guided out, preventing water from dripping onto the indoor floor.
