Abstract
Description
Technical Field
[0001] This utility model relates to the field of building ventilation device technology, and in particular to an automatic windproof and rainproof louver device for coastal equipment rooms. Background Technology
[0002] Equipment rooms, such as electrical equipment rooms and fire protection equipment rooms, contain equipment that requires continuous heat dissipation. To ensure the normal operation of this equipment, ventilation openings with louvers are usually installed on the walls of the equipment room to achieve natural ventilation and heat dissipation.
[0003] However, this conventional design faces significant challenges in coastal areas. These regions frequently experience sudden strong winds and heavy rainfall. If management fails to close windows promptly, wind and rain can easily penetrate the equipment room through the louvered ventilation openings. Furthermore, the humid air and high salt content of rainwater in coastal areas are highly corrosive. If rainwater or large amounts of humid air accompanied by strong winds enter the equipment room, it can accelerate corrosion and shorten the equipment's lifespan.
[0004] Because the opening and closing of windows relies entirely on manual operation by management personnel, reliability is low. In situations where no one is on duty or the weather changes abruptly, losses can easily occur due to failure to close windows in a timely manner. Therefore, there is an urgent need for a louver device that can automatically respond to wind and rain, promptly close ventilation openings, and automatically reset itself after the weather improves, to ensure the safe and stable operation of indoor equipment in coastal facilities. Utility Model Content
[0005] To solve the above-mentioned technical problems, this utility model provides an automatic windproof and rainproof louver device for coastal equipment rooms. The louver device has a simple structure, requires no external power, and can automatically open and close according to weather conditions.
[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: an automatic windproof and rainproof louver device for coastal equipment rooms is provided, including a louver with a number of blades, ventilation openings formed between adjacent blades, and also including a movable baffle, a wind-receiving plate and a linkage structure.
[0007] The movable baffle is positioned close to the louvers and can move up and down. The movable baffle is equipped with a baffle plate. In the initial position, the baffle plate is offset from the position of the vent to open the vent.
[0008] The wind-receiving plate is movable, and the linkage structure connects the wind-receiving plate and the movable baffle.
[0009] When the wind-receiving plate is subjected to wind or rain impact, the wind-receiving plate moves under the force and drives the movable baffle to move upward through the linkage structure, so that the position of the baffle coincides with the ventilation opening to close the ventilation opening.
[0010] When the wind or rain impact disappears, the wind-receiving plate resets, and the movable baffle moves downward to its initial position under the action of gravity.
[0011] As a further improvement of this utility model, it also includes a rotating shaft, through which the wind-receiving plate is rotatably mounted; the initial position of the wind-receiving plate faces obliquely downward, forming an angle of 10° to 80° with the horizontal plane, and when the wind-receiving plate is subjected to wind force or rain impact force, the wind-receiving plate rotates downward.
[0012] As a further improvement of this utility model, an extension rod is also provided between the wind-receiving plate and the rotating shaft.
[0013] As a further improvement of this utility model, the wind-receiving plate is provided with a water collection trough for collecting rainwater, and the wind-receiving plate can rotate downward under the influence of the weight of the rainwater in the water collection trough.
[0014] As a further improvement of this utility model, the linkage structure includes a hook disposed on the wind receiving plate and a hanging hole disposed on the movable baffle. The hook is fastened to the hanging hole. The hook and the wind receiving plate are respectively located on the front and rear sides of the rotating shaft. When the wind receiving plate rotates downward, the hook rotates upward and drives the movable baffle to move upward.
[0015] As a further improvement of this utility model, a vertical guide rail is also provided, and the movable baffle is movably mounted on the vertical guide rail.
[0016] As a further improvement of this utility model, at least one of the louvers, movable baffle, wind-receiving plate and linkage structure is made of corrosion-resistant material.
[0017] The beneficial effects of this utility model are as follows: The louver device uses wind and rainwater as driving sources, requiring no electricity or manual intervention. It can automatically respond to wind and rain, promptly closing the ventilation openings to prevent wind and rain from entering the equipment room. It automatically resets after the weather improves to allow for ventilation and heat dissipation, thus achieving automated management of the louvers and ensuring the safe, stable operation and service life of the equipment inside the coastal facility. The louver device adopts a purely mechanical linkage structure, without complex circuits or easily damaged parts, and features a simple structure, low failure rate, and long service life.

[0022] The present invention will be further described below with reference to specific embodiments and accompanying drawings.
[0023] like Figure 1-3 As shown, a louver 1 device for a coastal equipment room includes a louver 1, a movable baffle 2, a wind-receiving plate 3, and a linkage structure.
[0024] The louver 1 is fixedly installed on the wall of the equipment room ventilation position. It has several blades spaced from top to bottom, and ventilation openings 11 are formed between adjacent blades for ventilation and heat dissipation.
[0025] Vertical guide rails 21 are installed on both sides of the wall of the ventilation position, and the vertical guide rails 21 are located outside the louver 1. The movable baffle 2 is installed on the vertical guide rails 21 and is adjacent to the louver 1. The vertical guide rails 21 provide precise guidance and constraint for the movement of the movable baffle 2, preventing the movable baffle 2 from shaking, jamming or even deviating during the movement, thus improving the movement stability of the movable baffle 2. A baffle plate 22 is installed on the movable baffle 2, the size of which matches the ventilation opening 11. In the initial position, that is, in normal weather, the movable baffle 2 is located at the lowest point of the vertical guide rail 21 under the action of gravity. At this time, the baffle plate 22 is offset from the ventilation opening 11, and the ventilation opening 11 is fully open to achieve smooth ventilation.
[0026] The rotating shaft 31 is fixedly mounted on the wall of the ventilation position. The wind-receiving plate 3 is rotatably mounted on the rotating shaft 31 via bearings and is located outside the movable baffle 2. When the wind-receiving plate 3 is subjected to wind or rain impact, the wind-receiving plate 3 rotates downward; when the wind or rain impact disappears, the wind-receiving plate 3 moves upward and returns to its initial position. The size and counterweight of the wind-receiving plate 3 can be adjusted according to the weight of the movable baffle 2.
[0027] Furthermore, the wind-receiving plate 3 is rotatably mounted on the rotating shaft 31 via the extension rod 33. The function of the extension rod 33 is twofold: first, to extend the lever arm so that the wind-receiving plate 3 can exert a greater force on the hook 4 when rotating downwards, so as to lift and move the movable baffle 2 upwards; second, to increase the distance between the wind-receiving plate 3 and the movable baffle 2. When the wind blows onto the movable baffle 2, it will rebound. The rebounding wind can easily cancel out the downward rotation force of the movable baffle 2. When the distance between the wind-receiving plate 3 and the movable baffle 2 increases, the force exerted on the movable baffle 2 by the rebounding wind becomes weaker, thereby reducing the occurrence of this situation.
[0028] Furthermore, the initial position of the wind-receiving plate 3 is set to face diagonally downwards, forming an angle of 10° to 80° with the horizontal plane, preferably 45° in this embodiment. This tilt angle design brings two beneficial effects: first, it can efficiently receive wind pressure and effectively convert horizontal wind force into driving torque; second, it can better receive and collect rainwater as a slope.
[0029] Furthermore, the sensitivity of the wind-receiving plate 3 has been improved in this embodiment. A water collection trough 32 is provided at the bottom of the wind-receiving plate 3. The provision of this water collection trough 32 significantly improves the device's response sensitivity to rainfall. It can collect rainwater, and the weight of the accumulated rainwater increases the downward rotation torque of the wind-receiving plate 3. With the above configuration, even in light rain with low wind speeds, the weight of the rainwater in the water collection trough 32 is sufficient to trigger the wind-receiving plate 3 to move, achieving a full coverage response to windy and rainy weather. The bottom of the water collection trough 32 is provided with a small hole for drainage. The diameter of this hole is configured such that its drainage speed is much lower than the water accumulation speed of the water collection trough 32, allowing the rainwater on the water collection trough 32 to drain slowly after the rain stops.
[0030] The preferred linkage structure is a simple and efficient lever-hook mechanism, including a hook 4 fixed to the leeward side of the wind-receiving plate 3 and a hanging hole 41 on the movable baffle 2. The hook 4 and the plate body of the wind-receiving plate 3 are located on the front and rear sides of the rotating shaft 31, respectively, forming a force-saving lever. The hook 4 is fastened into the hanging hole 41 of the movable baffle 2. When the wind-receiving plate 3 is rotated downward by an external force, the hook 4 on the other side of the lever will move upward, directly pulling the movable baffle 2 upward through the hanging hole 41. This linkage structure converts the rotational motion of the wind-receiving plate 3 into the linear motion of the movable baffle 2, and has the characteristics of simple structure, direct power transmission, and extremely low maintenance cost.
[0031] Furthermore, the louvers 1, movable baffle 2, wind-receiving plate 3, rotating shaft 31, and linkage structure are all preferably made of corrosion-resistant materials, such as stainless steel, aluminum alloy, or engineering plastics. The movable baffle 2 and wind-receiving plate 3 are made of lightweight engineering plastics to minimize their weight, facilitating movement by the impact of wind and rain. This material selection ensures the entire device maintains a long service life and stable performance even in harsh coastal climates, preventing malfunctions due to corrosion.
[0032] Furthermore, a drainage channel 5 is provided on the wall below the movable baffle 2 so that rainwater blocked by the movable baffle 2 can be discharged from the drainage channel 5.
[0033] The working process of the above-mentioned venetian blind 1 device is as follows:
[0034] In normal weather conditions with no wind or light wind, the wind-receiving panel 3 maintains its initial tilt. The movable baffle 2 is positioned at the bottom of the vertical guide rail 21 under its own weight, the baffle 22 does not block the ventilation opening 11, and the louver 1 device remains open for ventilation.
[0035] In windy or rainy weather, the wind pressure, the impact force of rainwater, or the weight of rainwater in the water collection trough 32 together or separately generate a downward torque on the wind-receiving plate 3, causing the wind-receiving plate 3 to rotate downward around the rotating shaft 31. Through the linkage structure, the movable baffle 2 is driven to move upward along the vertical guide rail 21, so that the baffle 22 moves to the position of closing the ventilation opening 11, and the louver 1 device is in a closed state.
[0036] When the wind stops and the rain ceases, the rainwater on the water collection tank 32 evaporates or leaks out through the small holes, and the external force disappears. Under its own weight, the movable baffle 2 moves downward along the vertical guide rail 21 and drives the wind-receiving plate 3 to reset through the linkage structure, and the vent 11 reopens to the ventilation state.
[0037] The above-mentioned louver device has the following effects:
[0038] Fully automatic opening and closing: Using wind and rain as the driving source, it can automatically close in windy and rainy weather and automatically open when the weather improves, achieving automatic management without the need for electricity or manual intervention.
[0039] Dual triggering mechanism: The device responds to both wind and rain simultaneously. The downward-sloping design of the wind-receiving plate 3 and the introduction of the water collection tank 32 ensure that the closed ventilation opening 11 can be reliably triggered in any weather conditions, including strong winds, heavy rain, light rain, or mixed wind and rain, resulting in high sensitivity.
[0040] Simple and reliable structure: It adopts a pure mechanical structure, combining the lever principle with gravity reset, without complex circuits and vulnerable parts, resulting in a low failure rate and long service life.
[0041] Highly targeted: Specifically designed for coastal environments, the use of corrosion-resistant materials effectively solves the durability problem of the device in harsh environments, ensuring its long-term effective operation.
[0042] The above-described embodiments are merely illustrative of this utility model. Any equivalent embodiments made by those skilled in the art without departing from the technical features disclosed in this utility model, and without departing from the technical features of this utility model, shall still fall within the scope of the technical features of this utility model.
