Abstract
Description
Technical Field
[0001] This application relates to the field of ventilation technology, and in particular to a foldable ventilation and rain cover. Background Technology
[0002] In numerous scenarios such as industrial production, construction, and the operation of various equipment, ventilation systems are crucial facilities for ensuring ambient air circulation, normal equipment operation, and personnel health. The installation of a ventilation system requires the creation of airflow channels on the target device for air circulation. During operation, the ventilation system drives airflow between the inside and outside of the target device through these channels, achieving ventilation and improving the internal environment of the target device.
[0003] Because the airflow channels of the target device are usually directly exposed to the external environment, they are susceptible to rainwater intrusion. Rainwater entering the airflow channels may damage the electrical components inside the target device or cause corrosion of the device structure, affecting the normal operation and lifespan of the internal equipment. It may also trigger a series of other problems, such as mold growth and short circuits.
[0004] Currently, there are some fixed ventilation and rain covers on the market. While these covers can block rainwater to some extent, in addition to fixing the airflow channel, they have many drawbacks. Fixed rain covers are large in size, take up a lot of space, and are extremely inconvenient to transport and store, increasing transportation costs and storage difficulties. Utility Model Content
[0005] To reduce the space occupied during the transportation and storage of rain covers, this application provides a foldable ventilation rain cover.
[0006] The foldable ventilation and rain cover provided in this application adopts the following technical solution:
[0007] A foldable ventilation and rain cover includes a connecting frame, on which multiple baffles are movably disposed, and adjacent baffles are detachably connected.
[0008] The multiple baffles have two states. In the first state, the multiple baffles are folded together to reduce the space occupied. In the second state, the multiple baffles are spliced together to form a shield. The shield forms a side opening facing the connecting frame, and a ventilation opening is formed at the lower end of the shield.
[0009] By adopting the above technical solution, multiple detachably connected baffles are movably installed on the connecting frame, giving the rain cover a foldable function. In the first state, the multiple baffles fold together, greatly reducing the space occupied, facilitating transportation and storage, and reducing transportation costs and storage space requirements. In the second state, the multiple baffles are spliced together to form a cover, with side openings on the side walls of the cover for connecting airflow channels, and ventilation openings at the bottom of the cover. This not only protects the airflow channels from rain but also ensures the ventilation conditions required for the normal operation of the equipment inside the target device, ensuring normal ventilation.
[0010] Optionally, the baffle includes one or more connecting plates that are hinged to each other. In the second state, adjacent connecting plates that are not hinged to each other can be detachably connected.
[0011] By adopting the above technical solution, the baffle is composed of one or more connecting plates that are hinged to each other. When the multiple connecting plates are unfolded and spliced into a baffle, adjacent connecting plates that are not hinged can be detached and connected, which makes it convenient for the operator to flexibly fold and splice the baffle.
[0012] Optionally, the connecting frame is provided with two sets of baffles, each set of baffles includes two connecting plates that are hinged to each other, and one of the two connecting plates in the same set is hinged to the connecting seat; in the second state, adjacent connecting plates that are not hinged are connected to each other, and the four connecting plates form the baffle.
[0013] By adopting the above technical solution, two sets of baffles are configured on the connecting frame. Each set of baffles consists of two connecting plates that are hinged to each other, and one of the connecting plates is hinged and fixed on the connecting frame.
[0014] In the first state, the two connecting plates corresponding to the same baffle are folded together, and then the two sets of baffles are folded to make the folded structure more compact and reasonable, and occupy less space.
[0015] In the second state, adjacent connecting plates without hinges are connected to each other, so that the four connecting plates can cooperate to form a more stable shield, providing reliable rain protection for the airflow channel.
[0016] Optionally, a connecting seat is fixedly connected to the connecting frame at the position corresponding to the connecting plate, and the connecting plate is hinged to the connecting seat. The connecting seats have different specifications and are used to adjust the distance between the connecting plate and the connecting frame.
[0017] By adopting the above technical solution, the two connecting plates near the connecting frame are connected to the connecting frame through connecting seats of different specifications, so that when the two sets of connecting plates are folded, the four connecting plates can be arranged at intervals along the thickness direction of the connecting frame, which facilitates the storage of the cover.
[0018] Optionally, in the second state, adjacent connecting plates that are not hinged are engaged with each other.
[0019] By adopting the above technical solution, with multiple connecting plates unfolded to form a cover, adjacent connecting plates without hinges interlock. This connection method is simple and quick to operate, allowing for rapid assembly and disassembly without additional tools, greatly improving installation and disassembly efficiency and saving time and labor costs. At the same time, the interlocking structure has a certain connection strength, ensuring a stable connection between the covers during normal use, preventing loosening and ensuring the rainproof effect and structural stability of the rain cover.
[0020] Optionally, in the second state, between adjacent connecting plates that are not hinged, one of the connecting plates is provided with a latching protrusion, and the other connecting plate is provided with a latching groove for engaging with the latching protrusion.
[0021] By adopting the above technical solution, when multiple connecting plates are unfolded to form a shield, the snap-fit protrusion on one of the connecting plates engages with the snap-fit groove on the other connecting plate, thereby achieving the snap-fit cooperation between the adjacent connecting plates and ensuring the structural stability of the rain shield.
[0022] Optionally, in the second state, the connecting plate above the shield covers the connecting plate on the side wall of the shield.
[0023] By adopting the above technical solution, in the second state, the connecting plate above the shield covers the connecting plate on the side wall of the shield. This structural design can reduce the infiltration of rainwater from the connection between the top of the shield and the side wall, which is beneficial to enhance the waterproof performance of the rain shield, provide more reliable rain protection for the airflow channel, and reduce the damage of rainwater to the internal equipment of the target device.
[0024] Optionally, in the first state, the connecting plate furthest from the connecting frame is connected to the connecting frame via a threaded component.
[0025] By adopting the above technical solution, in the first state, the connecting plate farthest from the connecting frame is connected to the connecting frame by a threaded component. This fixing method can ensure the overall structural stability of the rain cover in the folded state, prevent the connecting plate from shaking or falling apart during transportation or storage, avoid damage to the baffle due to collisions or other reasons, and ensure the integrity and reusability of the rain cover. At the same time, the threaded component connection method has the characteristics of reliable connection and easy disassembly, making it convenient to quickly unfold and use the rain cover when needed.
[0026] In summary, this application includes at least one of the following beneficial technical effects:
[0027] 1. Multiple detachable baffles are movably installed on the connecting frame, giving the rain cover a foldable function. When the multiple baffles are folded together, the space occupied is greatly reduced, making it convenient for transportation and storage. When the multiple baffles are spliced together to form a cover, the side wall of the cover forms a side opening for connecting the airflow channel, and the lower end of the cover forms a ventilation opening. While providing rain protection for the airflow channel, it ensures the ventilation conditions required for the operation of the equipment inside the target device, ensuring normal ventilation and exhaust.
[0028] 2. When multiple connecting plates are spliced together to form a cover, adjacent connecting plates that are not hinged are interlocked. This connection method is simple and quick to operate, and can be quickly assembled and disassembled without additional tools, which greatly improves the efficiency of installation and disassembly and saves time and labor costs.

[0036] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail.
[0037] This application discloses a foldable ventilation and rain cover. For example... Figure 1 and Figure 2The foldable ventilation and rain cover includes a connecting frame 10 and multiple baffles 11. The connecting frame 10 serves as the mounting base for the entire rain cover and is installed on a target device, such as an energy storage container, a power distribution room, or a production workshop requiring ventilation. The target device has an airflow channel for airflow, and the airflow channel is positioned opposite the opening 15 of the connecting frame 10. Multiple baffles 11 are movably mounted on the connecting frame 10, with a detachable connection between adjacent baffles 11. This design allows the baffles 11 to be folded and spliced to meet the needs of different usage scenarios. Folding the baffles 11 reduces space occupation and facilitates transportation; unfolding and splicing multiple baffles 11 forms a cover 14, which is used to cover the airflow channel, protecting it from rain and foreign objects.
[0038] Specifically, each baffle 11 may include a connecting plate 20 or a plurality of interconnected connecting plates 20. One of the connecting plates 20 in each baffle 11 is connected to the connecting frame 10 via a connecting seat 17, and the connecting plate 20 is hinged to the corresponding connecting seat 17.
[0039] In this embodiment, two baffles 11 are provided on the connecting frame 10, with each baffle 11 located on either side of the opening 15 of the connecting frame 10. Each baffle 11 has two connecting plates 20, and the two connecting plates 20 corresponding to the same baffle 11 are hinged to each other via a first hinge. Of the two connecting plates 20 of each baffle 11, one connecting plate 20 is hinged to a corresponding connecting seat 17 via a second hinge. The connecting seats 17 corresponding to the two baffles 11 have different specifications, meaning that one connecting seat 17 can increase the distance between the corresponding connecting plate 20 and the connecting frame 10, so that when the two baffles 11 are stacked together, the four connecting plates 20 can be spaced apart along the thickness direction of the connecting frame 10.
[0040] When the connecting plates 20 of the two baffles 11 are flipped and unfolded, the four connecting plates 20 are spliced together to form a baffle 14, and adjacent connecting plates 20 without hinges are detachably connected. The detachable connection method can be bolted or snap-fit, etc. In this embodiment, with the connecting plates 20 unfolded and spliced together, adjacent connecting plates 20 without hinges are snap-fitted together. Specifically, for adjacent connecting plates 20 without hinges, a groove 13 is provided on the edge of one connecting plate 20, and a protrusion 12 is provided at the corresponding position of the adjacent connecting plates 20. The snap-fit is achieved by the engagement of the protrusion 12 and the groove 13. This connection method is convenient for installation and disassembly, and also ensures the stability of the connection.
[0041] The folded storage state of the two baffles 11 is designated as the first state. In the first state, the two baffles 11 fold together to reduce the space occupied. At this time, the connecting plate 20 furthest from the connecting frame 10 is connected to the connecting frame 10 via a threaded component (not shown in the figure). In specific operation, the two baffles 11 are folded sequentially, so that each connecting plate 20 folds and moves closer together. After the four connecting plates 20 are folded, the connecting plate 20 furthest from the connecting frame 10 is fixedly connected to the connecting frame 10 using bolts, nuts, or other threaded components. This prevents the baffles 11 from unfolding on their own when not in use, ensuring the stability of the folded state, and also facilitating storage and transportation. Specifically, a nut is installed on the connecting frame 10. This nut can be a rivet nut. A through hole is made on the connecting plate 20 furthest from the connecting frame 10. After the bolt passes through the through hole, the rivet nut on the connecting frame 10 is tightened, thus achieving the fixing effect of the four connecting plates 20 in the folded state.
[0042] The state in which the two baffles 11 are unfolded and spliced together is referred to as the second state. In the second state, the two baffles 11, that is, the four connecting plates 20, are spliced together to form a baffle 14, and the side wall of the baffle 14 forms a side opening facing the connecting frame 10. The connecting frame 10 is fixedly connected to the position of the airflow channel outside the target device, so that the baffle 14 covers the airflow channel and communicates with the airflow channel through the side opening. The lower end of the baffle 14 forms a vent 16, and the airflow channel interacts with the outside air through the vent 16 for ventilation.
[0043] During assembly, adjacent connecting plates 20 between different baffles 11 are connected by snap-fit, so that each baffle 11 is tightly spliced together to form a complete baffle 14 structure. At this time, the connecting plate 20 on the top of the baffle 14 covers the connecting plate 20 on the side wall of the baffle 14. This covering method can enhance the sealing and rainproof effect of the baffle 14, preventing rainwater from entering the airflow channel from the splicing gaps. The setting of the vent 16 ensures that the fan can ventilate normally during operation and its performance will not be affected by the presence of the baffle 14. For example, if the target device is equipped with ventilation equipment at the location of the airflow channel, and the airflow channel is located inside the baffle 14, air can interact through the airflow channel on the target device and the vent 16 of the baffle 14, providing the necessary conditions for the operation of the ventilation system.
[0044] like Figure 3 and Figure 4Specifically, regarding the two baffles 11, the two connecting plates 20 of one baffle 11 are designated as the first plate 21 and the second plate 22, respectively, and the two connecting plates 20 of the other baffle 11 are designated as the third plate 23 and the fourth plate 24, respectively. The first plate 21 and the third plate 23 are hinged to the connecting seats 17 on both sides of the connecting frame 10, the second plate 22 is hinged to the end of the first plate 21 facing away from the connecting frame 10, and the fourth plate 24 is hinged to the upper end of the third plate 23.
[0045] like Figure 4 In the first state, i.e. the state in which the two baffles 11 are folded, the first plate 21 is folded and close to the connecting frame 10, the second plate 22 is flipped to fit the side of the first plate 21 away from the connecting frame 10; the third plate 23 is flipped to fit the second plate 22, the fourth plate 24 is flipped to fit the third plate 23, and the fourth plate 24 is the connecting plate 20 farthest from the connecting frame 10.
[0046] like Figure 5 , Figure 5 The states a, b, c, d, and e in the diagram represent the unfolding process of the two baffles 11. During this process, the operator first flips the third plate 23 and the fourth plate 24 synchronously away from the second plate 22 (states a to b); then, the first plate 21 and the second plate 22 synchronously flip away from the connecting frame 10 (states b to c), completing the initial flipping. Next, the operator flips the second plate 22 towards the third plate 23 and engages the end of the second plate 22 away from the first plate 21 with the end of the third plate 23 away from the connecting frame 10 (states c to d). Finally, the operator flips the fourth plate 24 towards the first plate 21, so that the fourth plate 24 covers the first plate 21, the second plate 22, and the third plate 23, and engages the fourth plate 24 with the upper ends of the first plate 21 and the second plate 22, completing the splicing of the baffle 14 (states d to e). In this state, the first plate 21, the second plate 22, and the third plate 23 serve as the side plates of the cover 14, and the fourth plate 24 serves as the top plate of the cover 14.
[0047] like Figure 6 , Figure 6The state fghij in the diagram is used to represent the folding process of the two baffles 11. In this process, the fourth plate 24 is first flipped upwards, and the interlocking effect with the first plate 21 and the second plate 22 is released. Then, the second plate 22 is flipped away from the connecting frame 10, and the interlocking effect with the third plate 23 is released, so that the first plate 21 and the second plate 22 fold together, and the third plate 23 and the fourth plate 24 fold together, i.e., from state f to state g and then to state h. By flipping the first plate 21 together with the second plate 22 towards the connecting frame 10, i.e., from state h to state i. Finally, by flipping the third plate 23 together with the fourth plate 24 towards the connecting frame 10, the first plate 21, the second plate 22, the third plate 23 and the fourth plate 24 are folded sequentially away from the connecting frame 10, i.e., from state i to state j, thus achieving the folding effect of the two baffles 11.
[0048] The principle of this embodiment is as follows: In practical applications, the connecting frame 10 is first fixed to the outside of the airflow channel of the target device using bolts or other connectors. When the baffle 14 is needed for rain protection, the baffle 11, which is in a folded state (first state), is unfolded. Adjacent connecting plates 20 between different baffles 11 are connected by snap-fit, so that the baffles 11 are spliced together to form the baffle 14 (second state). At this time, the connecting plate 20 on top of the baffle 14 covers the side wall connecting plate 20, forming a complete rainproof structure to provide rain protection for the fan. When the baffle 14 is not needed or needs maintenance or storage, the snap-fit connection between the baffles 11 is first released, then the baffles 11 are folded, and finally, the connecting plate 20 furthest from the connecting frame 10 is fixed to the connecting frame 10 using threaded parts, so that the baffle 14 is in a folded state for easy handling and storage.
[0049] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
