Description

Technical Field

[0001] This invention relates to the field of ventilation louvers, and in particular to an adjustable opening and closing ventilation louver. Background Technology

[0002] Ventilation louvers are mainly used on the roof of factory buildings. Their main functions are to improve the overall ventilation of the factory and provide some light transmission, thus providing a better working environment for workers. However, current ventilation louvers are mainly designed for coastal areas or regions with high rainfall. But some parts of inland my country are relatively arid and windy, and some factories are located in inland areas. Therefore, coastal rainproof louvers are no longer suitable for these areas, for the following reasons: Due to the relatively dry environment and strong winds and sandstorms, the ventilation louvers cannot prevent the top of the louvers from being covered by wind and sand for a long time, which will lead to a decrease in light transmittance. Manual cleaning is required to ensure light transmittance. Due to the dry weather, there is a large temperature difference between day and night in the windy and sandy areas, especially at night. Therefore, it is necessary to keep the interior of the factory warm, so better insulation measures are needed. Based on the above problems, a new type of ventilation tower specifically designed for windy and sandy environments needs to be redesigned.

[0003] Therefore, we propose an adjustable openable and closed ventilation louver to solve the above problems. Summary of the Invention

[0004] The purpose of this invention is to provide an adjustable openable and closed ventilation louver to solve the problems mentioned in the background art. The technical solution of this invention addresses the problem that the existing technical solutions are too simplistic and provides a solution that is significantly different from the existing technology.

[0005] To achieve the above objectives, the present invention provides the following technical solution: An adjustable ventilated louver includes an eaves and an inner rotating cylinder. An outer protective layer is installed on the top of the eaves, and the top of the eaves is slidably connected to the inner rotating cylinder through a slot. Ventilation holes are provided on the surface of the inner rotating cylinder, and a closing door is installed between two adjacent ventilation holes. A scraper is installed on the inner side of the outer protective layer, and a connecting shaft is provided at the axis of the inner rotating cylinder. Passive fans are installed at both ends of the connecting shaft.

[0006] In a further embodiment, a first water seepage hole is provided at the junction of the outer protective layer and the eaves.

[0007] In a further embodiment, the scraper is in contact with the outer wall of the inner rotating cylinder, and a second water seepage hole is provided on the surface of the scraper.

[0008] In a further embodiment, automatic closing doors are installed at both ends of the outer protective layer, and a temperature sensor is installed on the inner side of the outer protective layer.

[0009] In a further embodiment, the two passive fan inlets are oriented in the same direction.

[0010] In a further embodiment, the closed door can be rotated to the inside of either of the two ventilation holes.

[0011] Compared with the prior art, the beneficial effects of the present invention are: The key feature of this invention is that, driven by natural wind, a passive fan rotates the inner cylinder. During rotation, a scraper naturally removes dust and other adhering substances from the surface of the inner cylinder. The device features several ventilation holes and several closing doors. The ventilation holes maintain air permeability, allowing air to pass through while simultaneously venting it outwards. The closing doors automatically close at the highest point of the inner cylinder due to gravity and open at the lowest point, ensuring both ventilation and preventing rainwater from entering the factory. A temperature sensor further controls the automatic closing doors, reducing ventilation efficiency in low-temperature environments and maintaining a stable factory temperature. This equipment is particularly suitable for inland areas, especially regions with large temperature differences and high sand content, providing low-temperature insulation while preventing reduced light transmission due to wind and sand.

Furthermore, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined with "first," "second," etc., may explicitly or implicitly include one or more of that feature. In the description of this invention, unless otherwise stated, "a plurality of" means two or more.

[0020] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; 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; and they can refer to the internal connection of two components. Those skilled in the art will understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. Example 1

[0022] Please see Figure 1-6In this embodiment of the invention, an adjustable openable and closed ventilation louver includes an eaves 1 and an inner rotating cylinder 3. An outer protective layer 2 is installed on the top of the eaves 1. The top of the eaves 1 is slidably connected to the inner rotating cylinder 3 through a slot. Ventilation holes 4 are provided on the surface of the inner rotating cylinder 3. A closing door 5 is installed between two adjacent ventilation holes 4. A scraper 6 is installed on the inner side of the outer protective layer 2. A connecting shaft is provided at the axis of the inner rotating cylinder 3. Passive fans 7 are installed at both ends of the connecting shaft. A first seepage hole 201 is provided at the joint between the outer protective layer 2 and the eaves 1. The first seepage hole 201 provided at the outer protective layer 2 allows rainwater to drain normally to the top of the eaves 1, allowing the rainwater to flow along the tilt direction of the eaves 1, thus achieving a basic drainage effect.

[0023] Automatic closing doors 8 are installed at both ends of the outer protective layer 2. A temperature sensor is installed on the inner side of the outer protective layer 2. The automatic closing doors 8 can close when the ambient temperature is low. They can be manually activated to close, or the temperature sensor can sense that the ambient temperature is low and activate the motor at the shaft end of the automatic closing door 8, and then close the automatic closing door 8. Example 2

[0024] Please see Figure 1-6 The difference from Embodiment 1 is that the scraper 6 is in contact with the outer wall of the inner rotating cylinder 3, and the scraper 6 has a second water seepage hole 601 on its surface. The main function of the scraper 6 is to scrape off the dust or stains that have been wetted by rainwater and have an adhesive effect on the surface of the inner rotating cylinder 3. At the same time, the second water seepage hole 601 allows water on the surface of the scraper 6 to be quickly discharged outwards.

[0025] Are the air inlets of the two passive fans 7 in the same direction? The passive fans 7 should be set in the same direction so that no matter where the wind blows in from, the two passive fans 7 can rotate in the same direction, avoiding the situation where the rotation directions are opposite and the forces cancel each other out. Example 3

[0026] Please see Figure 1-6 The difference from Embodiment 1 is that the closed door 5 can be rotated to the inside of any one of the ventilation holes 4 on both sides. The closed door 5 can be rotated to the position of any one of the ventilation holes 4 on its left and right sides. Because of the uncertainty of the rotation direction, if the closed door 5 can only rotate in one direction, there will always be a rotation direction that will cause the scraper 6 and the closed door 5 to get stuck together. Therefore, the closed door 5 is designed to be able to rotate to the position of any one of the ventilation holes 4 on both sides, so as to avoid the problem of getting stuck.

[0027] The working principle of this invention is: The wind mainly blows in through the closed door 5 of the outer protective layer 2. The closed door 5 is located on the front and rear sides, but the wind only blows in from one direction. When it blows in from any direction, it will drive the passive fan 7 to rotate, which will drive the connecting shaft to rotate. The connecting shaft will then drive the inner rotating cylinder 3 on the outside to rotate through the connecting rod. During the rotation, the scraper 6 can scrape off the dust on the surface at the same time. Meanwhile, the closed door 5 located below the inner rotating cylinder 3 will naturally fall downwards due to gravity and will not block any of the vent holes 4. At this time, the wind blows through the inside of the inner rotating cylinder 3 and can absorb the gas inside the factory to the outer layer through the open vent holes 4, thereby accelerating the exhaust from the inside of the factory. The closed door 5, which is vertically downward due to gravity, can also act like a small fan blade, accelerating the exhaust of the gas inside the factory to the outside. Secondly, it should be noted that when the closed door 5 passes the scraper 6, regardless of whether the inner rotating cylinder 3 rotates forward or backward, the closed door 5 will be stuck in the ventilation hole 4 on either side, keeping the ventilation hole 4 at the top closed and preventing rainwater from seeping into the factory through the ventilation hole 4. The automatic closing door 8 can close the outer protective layer 2 at the front and rear positions under the drive of the motor, or the automatic closing door 8 can be closed by controlling the motor through the internal temperature sensor. In low temperature environments, closing the door can prevent the temperature inside the factory from being lost excessively. This can minimize the risk of wind blowing in from the axial direction of the inner rotating cylinder 3 and prevent the inner rotating cylinder 3 from rotating. In this way, the wind can only blow through the upper layer of the outer protective layer 2. At the same time, since the vent 4 above the inner rotating cylinder 3 is closed, the space for ventilation is greatly reduced, which effectively prevents the temperature inside the factory from being lost excessively and causing sudden changes in temperature. To maximize light transmittance, the inner rotating cylinder 3 can be made of acrylic sheet.

[0028] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0029] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
