Description

Technical Field

[0001] This utility model relates to the field of ship cabin ventilation technology, and more specifically, to an upper deck ship cabin ventilation device. Background Technology

[0002] Upper decks typically employ a closed structure to ensure the safety of crew and equipment, thus requiring a ventilation system. The cabin ventilation device is a core component of the ship's ventilation system, designed to achieve air exchange between the interior and exterior of the cabin through natural or mechanical means, ensuring personnel health, equipment operational safety, and a comfortable cabin environment. Publication number CN205366037U provides a cabin ventilation device including a ventilation frame and louvers. The ventilation frame has several mounting holes, and the louvers are located inside the ventilation frame. A first push rod is connected to the rear end of the ventilation frame, and the first push rod is connected to a second push rod, which is mounted on a mounting bracket. A micro switch is provided between the louvers and the ventilation frame. A waterproof plate is installed on the ventilation frame, and a water storage box is located at the bottom of the ventilation frame. Several water guide holes are located on the outer side of the water storage box. Two water guide grooves are symmetrically arranged on the ventilation frame, and a sound-insulating and water-blocking plate is located on the rear side of the ventilation frame. The beneficial effects of this utility model are that when encountering large waves or rain, the louvers are closed and sealed, and seawater and rainwater are blocked outside by the waterproof plate. The water guide channel and water storage box set on the ventilation frame guide the rainwater and seawater out, improving the working environment inside the cabin. The noise inside the cabin is reduced by the sound-absorbing plate inside the soundproof and water-blocking plate.

[0003] However, existing technologies have some problems: existing upper deck ventilation devices directly deliver outside air into the deck. However, since the deck is on water and the outside air humidity is high, directly delivering air into the deck will result in high humidity inside the deck, which will cause mold and bacteria to grow, leading to rust and corrosion of metal parts and affecting the service life of equipment inside the deck. Therefore, we propose an upper deck ventilation device. Utility Model Content

[0004] One objective of this invention is to provide a new technical solution for an upper deck ventilation device.

[0005] According to a first aspect of the present invention, an upper deck ventilation device is provided, comprising a housing, on which ventilation holes are provided, louvers are rotatably connected to the inner wall of the ventilation holes, a sliding groove is provided on the inner wall of the ventilation holes, a liquid removal plate is slidably connected to the sliding groove, a fixing component is provided on the liquid removal plate for fixing the liquid removal plate, a support plate is fixedly connected to the inner wall of the housing, a suction component is provided on the support plate, and a drainage groove is provided on the housing, the drainage groove corresponding to the liquid removal plate.

[0006] Optionally, a connecting groove is provided on the inner wall of the ventilation hole of the outer casing, and a rotating shaft is fixedly connected in the connecting groove. The rotating shaft is fixedly connected to the louver, and the louver is rotatably connected to the outer casing through the rotating shaft.

[0007] Optionally, the rotating shaft has several grooves, a first spring is fixedly connected to the inner wall of the groove, a locking block is fixedly connected to the first spring, and a locking groove is formed on the inner wall of the outer shell connecting groove, and the locking block is engaged in the locking groove.

[0008] Optionally, the liquid removal plate includes a fixed frame and a filter plate, the fixed frame and the filter plate are detachably connected, the fixed frame is slidably connected in the groove of the outer shell, and a number of corrugated plates are fixedly connected to the inner wall of the fixed frame, the corrugated plates being evenly distributed on the fixed frame.

[0009] Optionally, the liquid removal plate further includes a fixing screw, the fixing frame has a threaded hole, the filter plate has a through hole, and the fixing screw passes through the through hole and is threaded into the threaded hole.

[0010] Optionally, the fixing component includes a fixing shaft, the fixing frame has a through hole, the fixing shaft is movably connected in the through hole, one end of the fixing shaft is fixedly connected to a knob, and the other end of the fixing shaft is fixedly connected to a fixing block.

[0011] Optionally, a fixing plate is rotatably connected to the fixing shaft, the fixing plate is slidably connected to the through hole of the fixing frame, and a second spring is fixedly connected to the fixing plate, the second spring being fixedly connected to the inner wall of the through hole.

[0012] Optionally, the outer casing is provided with a slide rail, the fixed shaft is slidably connected in the slide rail, the inner wall of the slide rail is provided with a rotating groove, the fixed block is rotatably connected in the rotating groove, the inner wall of the rotating groove is provided with a fixing groove, and the fixed block is engaged in the fixing groove.

[0013] Optionally, the suction assembly includes a motor, which is fixedly connected to a support plate, and a fan blade is fixedly connected to the output end of the motor.

[0014] According to one embodiment of this disclosure, moisture in the air is drained through a descaling plate to prevent excessive humidity inside the cabin. When airflow from outside the cabin passes through the descaling plate, the filter plates on the descaling plate filter the airflow, intercepting large particles to prevent them from entering the device and damaging the fan blades. The filtered gas then flows to multiple sets of corrugated plates. As the gas passes through the corrugated plates, the moisture in the gas impacts the plates due to inertia, causing the moisture to adhere to the plates and condense into water droplets that slide down the plates to the drainage channel, where they are discharged from the device. This reduces the moisture in the airflow, thereby reducing the humidity inside the upper cabin and preventing the growth of mold and bacteria, which can lead to rust and corrosion of metal parts and affect the service life of equipment inside the cabin.

[0015] This utility model is equipped with a fixing component. When installing the drain plate, the drain plate is inserted along the slide rail of the outer shell. When the drain plate moves to the bottom of the slide rail, the fixing shaft moves into the slide rail of the outer shell. At this time, pressing down the knob causes the fixing shaft and the fixing block to slide along the slide rail, while driving the fixing plate to compress the second spring and move within the through hole of the fixing frame until the fixing block moves into the rotating groove of the outer shell. Then, turning the knob drives the fixing shaft to rotate, thereby driving the fixing block to rotate along the rotating groove until the fixing block rotates to the fixing groove. At this time, releasing the knob causes the fixing plate to move upward due to the rebound force of the second spring, thereby driving the fixing shaft and the fixing block to move upward, and thus causing the fixing block to engage in the fixing groove to fix the drain plate. When it is necessary to clean or replace the drain plate, the above operation is repeated in reverse to remove it. The fixing component allows for quick installation and removal of the drain plate, facilitating its maintenance and cleaning.

[0028] Various exemplary embodiments of the present invention will now be described in detail with reference to the accompanying drawings. It should be noted that, unless otherwise specifically stated, the relative arrangement, numerical expressions, and values ​​of the components and steps set forth in these embodiments do not limit the scope of the present invention.

[0029] The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the invention or its application or use.

[0030] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and equipment should be considered part of the specification.

[0031] In all the examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values.

[0032] like Figure 1-9As shown, an upper deck ventilation device includes an outer shell 1 with ventilation holes. The outer shell 1 is welded from stainless steel plates. The main function of the outer shell 1 is to support the entire device and ensure its stable operation.

[0033] Furthermore, a louver 2 is rotatably connected to the inner wall of the ventilation hole. The grid structure of the louver 2 can block rain, snow, flying insects and other objects from entering the ventilation system, thus preventing equipment damage or blockage. A connecting groove is provided on the inner wall of the ventilation hole of the outer shell 1. A rotating shaft 8 is fixedly connected in the connecting groove. The rotating shaft 8 is fixedly connected to the louver 2. The louver 2 is rotatably connected to the outer shell 1 through the rotating shaft 8.

[0034] Furthermore, the rotating shaft 8 has several grooves, the inner wall of which is fixedly connected to a first spring 9, and the first spring 9 is fixedly connected to a locking block 10. The inner wall of the connecting groove of the outer shell 1 has a locking groove, and the locking block 10 is engaged in the locking groove.

[0035] Specifically, rotating the louver 2 will drive the rotating shaft 8 to rotate, and the rotating shaft 8 will drive the locking block 10 to rotate, thereby causing the locking block 10 to disengage from the current slot until it moves to the next set of slots and is fixed by the first spring 9, so that the louver 2 is fixed at the current angle. By adjusting the tilt angle of the louver 2, the air flow can be changed, thereby controlling the ventilation speed. At the same time, in the face of extreme weather such as heavy rain, the louver 2 can be rotated to form a sealed plate to prevent rainwater from entering the device.

[0036] Furthermore, a sliding groove is provided on the inner wall of the ventilation hole, and a liquid removal plate 3 is slidably connected on the sliding groove. The liquid removal plate 3 includes a fixed frame 31 and a filter plate 33. The fixed frame 31 and the filter plate 33 are detachably connected. The fixed frame 31 is slidably connected in the sliding groove of the outer shell 1. Several corrugated plates 32 are fixedly connected to the inner wall of the fixed frame 31. The corrugated plates 32 are evenly distributed on the fixed frame 31.

[0037] Furthermore, the liquid removal plate 3 also includes a fixing screw 34. The fixing frame 31 has a threaded hole, and the filter plate 33 has a through hole. The fixing screw 34 passes through the through hole and is threaded into the threaded hole. The fixing screw 34 is used to fix the filter plate 33, which facilitates replacement when the filter plate 33 is damaged, without having to replace the entire liquid removal plate 3.

[0038] Specifically, when the airflow outside the cabin passes through the descaling plate 3, the filter plate 33 on the descaling plate 3 filters the airflow, intercepting large particles and preventing them from entering the device and damaging the fan blades 62. The air filtered by the filter plate 33 then flows to multiple sets of corrugated plates 32. When the air passes through the corrugated plates 32, the moisture in the air will impact the corrugated plates 32 due to inertia, causing the moisture to adhere to the corrugated plates 32 and condense into water droplets, which slide down the corrugated plates 32 to the drainage channel 7 and be discharged from the device through the drainage channel 7. This reduces the moisture in the airflow, thereby reducing the air humidity in the upper cabin and preventing the growth of mold and bacteria, which can lead to rust and corrosion of metal parts and affect the service life of the equipment in the cabin.

[0039] Furthermore, a fixing component 4 is provided on the liquid removal plate 3. The fixing component 4 is used to fix the liquid removal plate 3. The fixing component 4 includes a fixing shaft 41. A through hole is opened on the fixing frame 31. The fixing shaft 41 is movably connected in the through hole. A knob 42 is fixedly connected to one end of the fixing shaft 41, and a fixing block 43 is fixedly connected to the other end of the fixing shaft 41.

[0040] Specifically, a fixing plate 44 is rotatably connected to the fixing shaft 41, the fixing plate 44 is slidably connected in the through hole of the fixing frame 31, and a second spring 45 is fixedly connected to the fixing plate 44, the second spring 45 is fixedly connected to the inner wall of the through hole.

[0041] Furthermore, a slide rail is provided on the outer shell 1, the fixed shaft 41 is slidably connected in the slide rail, a rotating groove is provided on the inner wall of the slide rail, the fixed block 43 is rotatably connected in the rotating groove, a fixing groove is provided on the inner wall of the rotating groove, and the fixed block 43 is snapped into the fixing groove.

[0042] Specifically, when installing the drain plate 3, insert the drain plate 3 along the slide of the outer casing 1. When the drain plate 3 moves to the bottom of the slide, the fixing shaft 41 moves into the slide of the outer casing 1. At this time, press down the knob 42 to make the fixing shaft 41 and the fixing block 43 slide along the slide, and at the same time drive the fixing plate 44 to compress the second spring 45 and move in the through hole of the fixing frame 31 until the fixing block 43 moves into the rotating groove of the outer casing 1. At this time, turn the knob 42 to drive the fixing shaft 41 to rotate, thereby driving the fixing block 43 to rotate along the rotating groove until the fixing block 43 rotates to the fixing groove. At this time, release the knob 42, and the fixing plate 44 will move upward due to the rebound force of the second spring 45, thereby driving the fixing shaft 41 and the fixing block 43 to move upward, so that the fixing block 43 is locked in the fixing groove to fix the drain plate 3. When it is necessary to clean or replace the drain plate 3, repeat the above operation in reverse to remove it. The fixing component 4 can quickly realize the installation and removal of the drain plate 3, which is convenient for maintenance and cleaning.

[0043] Furthermore, a support plate 5 is fixedly connected to the inner wall of the outer shell 1, and a suction assembly 6 is provided on the support plate 5. The suction assembly 6 includes a motor 61, which is fixedly connected to the support plate 5, and a fan blade 62 is fixedly connected to the output end of the motor 61.

[0044] Specifically, the motor 61 starts and drives the fan blades 62 to rotate, thereby creating a negative pressure environment inside the outer shell 1, which in turn causes the air outside the cabin to be drawn into the outer shell 1 due to the pressure difference, and finally flows into the cabin.

[0045] The outer casing 1 is provided with a drainage groove 7, which corresponds to the liquid removal plate 3. The drainage groove 7 is used to drain the water formed by the water removed by the liquid removal plate 3.

[0046] The aforementioned upper cabin ventilation device uses a desiccant plate 3 to remove moisture from the air, thus preventing excessive humidity inside the cabin. When airflow from outside the cabin passes through the desiccant plate 3, the filter plate 33 on the desiccant plate 3 filters the airflow, intercepting large particles and preventing them from entering the device and damaging the fan blades 62. The air filtered by the filter plate 33 then flows to multiple sets of corrugated plates 32. As the air passes through the corrugated plates 32, the moisture in the air impacts the corrugated plates 32 due to inertia, causing the moisture to adhere to the corrugated plates 32 and condense into water droplets, which slide down the corrugated plates 32 to the drainage channel 7 and are discharged from the device. This reduces the moisture in the airflow, thereby reducing the humidity inside the upper cabin and preventing the growth of mold and bacteria, which can lead to rust and corrosion of metal parts and affect the service life of equipment inside the cabin.

[0047] This utility model is equipped with a fixing component 4. When installing the drain plate 3, the drain plate 3 is inserted along the slide of the outer shell 1. When the drain plate 3 moves to the bottom of the slide, the fixing shaft 41 moves into the slide of the outer shell 1. At this time, pressing down the knob 42 causes the fixing shaft 41 and the fixing block 43 to slide along the slide, while driving the fixing plate 44 to compress the second spring 45 and move it in the through hole of the fixing frame 31 until the fixing block 43 moves into the rotating groove of the outer shell 1. At this time, rotating the knob 42 drives the fixing shaft 41 to rotate, thereby driving the fixing plate 44 to rotate. The fixed block 43 rotates along the rotating groove until it reaches the fixed groove. At this point, the knob 42 is released, and the fixed plate 44 moves upward due to the rebound force of the second spring 45. This causes the fixed shaft 41 and the fixed block 43 to move upward, thereby locking the fixed block 43 into the fixed groove and fixing the drain plate 3. When the drain plate 3 needs to be cleaned or replaced, the above operation can be repeated in reverse to remove it. The fixed component 4 allows for quick installation and removal of the drain plate 3, facilitating its maintenance and cleaning.

Those skilled in the art should understand that modifications can be made to the above embodiments without departing from the scope and spirit of the present invention.
