Description

Technical Field

[0001] This application relates to the field of marine technology, and in particular to a marine louver that prevents condensation dripping. Background Technology

[0002] Marine louvers are commonly installed in areas such as ship engine rooms and oil mist chambers to achieve cabin ventilation while also meeting safety requirements such as fire prevention and insect control. Existing conventional marine louvers mainly consist of a window frame, several window slats, and protective wire mesh. The window slats are mostly arranged horizontally or vertically and fixed inside the window frame, while the protective wire mesh is assembled on the outside of the window slats, forming a basic ventilation and protection structure.

[0003] As ship operating conditions become increasingly complex, especially in areas with high concentrations of high-temperature oil, gas, and water vapor, the aforementioned traditional louvers have gradually revealed significant shortcomings in practical use. Specifically, external spray liquids and high-temperature oil, gas, and water vapor, upon cooling, easily condense into droplets on the surface of the outer protective wire mesh. These droplets, under gravity, drip directly downwards onto the outside of the louvers, causing leakage. Simultaneously, condensate collected within the louvers themselves tends to accumulate at the bottom and overflow, with the dripping and overflowing liquid adhering directly to the hull plating or equipment exterior below the louvers. Oily condensate mixed with dust easily forms stubborn stains, severely polluting the exterior appearance and making cleaning extremely difficult, significantly increasing the workload for daily cleaning and maintenance by the crew. Long-term dripping also exacerbates the risk of plating corrosion, affecting the integrity of ship equipment and the hull's exterior. Summary of the Invention

In the diagram, M indicates the outer side of the marine louver to prevent condensation dripping, and N indicates the inner side of the marine louver to prevent condensation dripping. For example... Figures 1 to 3As shown, this embodiment provides a marine louver for preventing condensation dripping, comprising: a window frame body 100, window slats 300, a protective net 400, and a receiving component 500. The upper part of the window frame body 100 is mounted on an equipment wall 200; several window slats 300 are respectively arranged obliquely inside the window frame body 100, and both ends of each window slat 300 are connected to the window frame body 100; the protective net 400 is located on the side of the window frame body 100 opposite to the equipment wall 200, and the upper part of the protective net 400 is mounted on the window frame body 100; the receiving component 500 is located at the bottom of the window frame body 100, and vertically mounted between the lower part of the protective net 400 and the equipment wall 200; the receiving component 500 is used to collect condensate formed on the surface of the protective net 400 and to guide the collected condensate to an oil collection device connected to the receiving component 500. During ship operation, high-temperature oil and water vapor condenses on the surface of the protective net 400, forming condensate. The condensate drips under gravity into the receiving component 500, which collects the condensate and then directs it to an oil recovery device connected to the receiving component 500, thus achieving the collection, distribution, and discharge of the condensate. This embodiment, by installing a receiving component at the bottom of the window frame, better receives the condensate formed on the protective net surface, preventing leakage that could affect the ship's appearance and reducing the workload of daily maintenance for the crew. Simultaneously, directing the condensate to the oil recovery device forms a complete discharge path, achieving condensate recycling. The overall structure is compact and rationally arranged, without affecting ventilation function, and possesses strong versatility and adaptability.

[0025] In one embodiment, both ends of the window leaf 300 are movably connected to the window frame body 100, and the tilt angle of the window leaf 300 can be adjusted according to ventilation requirements.

[0026] In one embodiment, the receiving component 500 includes an outer receiving groove 510 and an inner receiving groove 530. The upper end of the external receiving groove 510 relative to the window frame body 100 is connected to the lower part of the protective net 400. The external receiving groove 510 extends to the outside of the protective net 400 on the side opposite to the window frame body 100 to receive condensate formed on the surface of the protective net 400. A first vent hole 520 is provided on the side of the external receiving groove 510 relative to the window frame body 100. The internal receiving groove 530 is connected to the lower part of the external receiving groove 510 and forms a groove structure. The internal receiving groove 530 and the external receiving groove 510 are connected through the first vent hole 520. In the vertical direction, the side of the internal receiving groove 530 opposite to the external receiving groove 510 is connected to the equipment wall 200. A second vent hole 540 is provided at the bottom of the internal receiving groove 530. The internal receiving groove 530 is connected to the oil collection device through the second vent hole 540. The condensate dripping and splashing from the surface of the protective net 400 is collected by the external receiving tank 510. The condensate in the external receiving tank 510 then flows into the internal receiving tank 530 through the first drain hole 520. The internal receiving tank 530 collects the condensate a second time. Finally, the condensate is guided to the oil collection device through the second drain hole 540 at the bottom of the internal receiving tank 530, thus completing the receiving, guiding and discharging of the condensate by the receiving component 500.

[0027] In this embodiment, the external receiving groove extends to the outside of the protective net, expanding the receiving range and better covering the area of ​​condensate dripping and splashing, resulting in better leak prevention. Simultaneously, the first vent hole connects to the internal receiving groove, and the second vent hole connects to the oil collection device, forming a directional flow path that allows condensate to flow smoothly within the receiving assembly, preventing liquid accumulation.

[0028] In one embodiment, multiple first vent holes 520 may be provided, evenly distributed on one side of the outer receiving groove 510 relative to the window frame body 100, to improve the efficiency of guiding condensate from the outer receiving groove 510 to the inner receiving groove 530. Optionally, multiple second vent holes 540 may be provided, evenly distributed at the bottom of the inner receiving groove 530, to improve the efficiency of guiding condensate from the inner receiving groove 530 to the oil collection device.

[0029] In one embodiment, the upper end of the outer receiving groove 510 relative to the side of the window frame body 100 is fixedly connected to the lower part of the protective net 400 by fasteners; the side of the inner receiving groove 530 opposite to the outer receiving groove 510 is fixedly connected to the equipment wall 200 by fasteners; the inner receiving groove 530 is welded to the outer receiving groove 510. In this embodiment, the outer receiving groove 510 is fixed to the window frame body 100 and the protective net 400 by fasteners, and the inner receiving groove 530 is fixed to the equipment wall 200 by fasteners, realizing the detachable installation of the receiving component 500 between the lower part of the protective net 400 and the equipment wall 200, which facilitates subsequent disassembly and maintenance. The welded connection between the outer receiving groove 510 and the inner receiving groove 530 ensures the sealing between them, avoiding the problem of condensate leakage in the connection gap. The installation method of the receiving component 500 provided in this embodiment can better adapt to the high vibration and high salt spray working environment of ships, and reduce the risk of component loosening and corrosion.

[0030] In one embodiment, the central axis of the first vent hole 520 is inclined downwards, so that the side of the first vent hole 520 away from the protective net 400 is lower than the side of the first vent hole 520 close to the protective net 400. The condensate collected in the external receiving tank 510, under the influence of gravity through the inclined first vent hole 520, can have its flow accelerated, achieving directional flow of the condensate without additional power. The inclination direction of the first vent hole 520 matches the flow trend of the condensate, ensuring that the condensate in the external receiving tank 510 can be smoothly introduced into the internal receiving tank 530.

[0031] Optionally, the inclination angle of the central axis of the first vent hole 520 is 10° to 20°. This embodiment provides a suitable inclination angle to ensure that the condensate can maintain a stable and unobstructed flow during ship operation, so that the condensate will not stagnate in the first vent hole 520 due to an inclination angle that is too small, nor will the condensate splash due to an inclination angle that is too large.

[0032] Optionally, an anti-sticking layer can be provided on the inner wall of the first vent hole 520 to prevent condensate from adhering and lingering in the first vent hole 520 and clogging the first vent hole 520.

[0033] Optionally, a discharge mesh is provided at the entrance of the first discharge hole 520 near the protective net 400, that is, at the entrance of the first discharge hole 520. The discharge mesh is used to intercept impurities and prevent the first discharge hole 520 from becoming blocked.

[0034] In one embodiment, the receiving component 500 further includes a shut-off valve disposed at the second drain hole 540; the shut-off valve is used to control the opening and closing of the second drain hole 540 according to the liquid level of the condensate in the internal receiving tank 530.

[0035] Furthermore, the receiving component 500 also includes a liquid level sensor and a controller. The liquid level sensor is installed on the inner wall of the internal receiving tank 530 to collect real-time liquid level data within the internal receiving tank 530. The controller is electrically connected to both the liquid level sensor and the shut-off valve. Based on the real-time liquid level data collected by the liquid level sensor, when the liquid level of the condensate in the internal receiving tank 530 reaches a preset value, the controller controls the shut-off valve to open, and the condensate is drained to the oil collection device through the second drain hole 540. Based on the real-time liquid level data collected by the liquid level sensor, when the liquid level of the condensate in the internal receiving tank 530 is lower than the preset value, the controller controls the shut-off valve to close, realizing temporary storage of the condensate in the internal receiving tank 530 and reducing equipment damage caused by continuous discharge of small amounts of condensate.

[0036] In one embodiment, the inner wall of the second drain hole 540 is provided with threads, and the second drain hole 540 is threadedly connected to the connecting pipe of the oil collection device. The second drain hole 540 stably drains to the oil collection device through the threaded pipe. The threaded connection not only ensures a tight connection, but also facilitates quick disassembly and installation, which is beneficial for later inspection and maintenance.

[0037] In one embodiment, the upper edge of the external receiving groove 510, opposite to the side of the window frame body 100, is provided with an upwardly extending baffle. This baffle prevents condensate from splashing out of the external receiving groove 510 from its upper edge. Some condensate drips onto the protective mesh surface and into the external receiving groove 510, while some splashes out from the protective mesh; these splashes are blocked by the baffle, preventing condensate from splashing out of the external receiving groove 510 from its upper edge. In this embodiment, the baffle further expands the condensate-receiving range of the external receiving groove 510, effectively intercepting splashed condensate.

[0038] In one embodiment, the diameter of the first drain hole 520 is smaller than that of the second drain hole 540 to prevent condensate accumulation in the internal receiving tank 530. The difference in diameter between the first drain hole 520 and the second drain hole 540 allows for orderly condensate drainage, preventing condensate accumulation and overflow in the internal receiving tank 530 and improving drainage stability. The smaller diameter of the first drain hole 520 allows condensate in the external receiving tank 510 to flow relatively slowly into the internal receiving tank 530, preventing splashing due to excessively fast flow. The larger diameter of the second drain hole 540 ensures rapid drainage of condensate from the internal receiving tank 530 to the oil collection device, improving drainage efficiency. It should also be noted that the first drain hole 520 and the second drain hole 540 are sequentially arranged along the condensate drainage path. In the embodiment shown in the figure, the first vent 520 is located above the second vent 540 in the vertical direction.

[0039] In one embodiment, the inner wall surface of the receiving component 500 that comes into contact with the condensate is provided with an anti-corrosion coating. The anti-corrosion coating in this embodiment can effectively resist corrosion, extend the service life of the receiving component, and reduce replacement and maintenance costs.
