A dustproof cover for the air outlet of a grain depot's air conditioning unit

Abstract

This utility model relates to the field of dustproof covers for air-conditioned compartments, specifically a dustproof cover for the air outlet of a grain depot's air-conditioned compartment. It includes a connecting pipe with a cover mechanism on its surface. The connecting pipe is fixedly connected to the air outlet of the air-conditioned compartment, improving air exchange efficiency. Two sets of flaps are connected to the mounting components via a connecting shaft, and the flaps can rotate relative to each other along the mounting components via bearings, thus diverting the airflow and improving airflow coverage efficiency. The cover mechanism is quickly fitted and connected to the connecting pipe via the mounting components. A limiting frame restricts the installation position of the mounting components, ensuring convenient disassembly and assembly of the cover mechanism. This solves the problems of cumbersome disassembly and assembly methods and inconvenience for automatic opening and closing in most traditional cover methods. Traditional covers often use screw fastening or clip nesting, requiring special tools for individual disassembly, resulting in long single-operation times.

[0002] Grain depots are short for grain warehouses and are the common name for grain storage enterprises. They are state-owned enterprises and an important part of China's grain enterprises. They are managed by the grain department and play a leading role in national grain reserves, local grain reserves, and grain circulation. Their main tasks are to complete all aspects of grain circulation, including receiving, storing, and transporting grain. To ensure the effectiveness of grain storage, grain depots are often equipped with dedicated air-conditioned warehouses.

[0003] The dust cover of the air outlet inside the air-conditioning compartment of the grain depot is an important component to ensure the efficient operation of the grain depot's air-conditioning system and maintain the quality of the grain. However, most traditional cover installation and removal methods are cumbersome and not easy to open and close automatically. Traditional covers are mostly fastened with screws or clips, requiring special tools (such as screwdrivers and wrenches) to disassemble them one by one. Each operation takes a long time. In addition, the air outlet of the grain depot's air-conditioning is usually located at a high place or in a narrow corner, requiring maintenance personnel to use ladders or climbing equipment, which further increases the difficulty of operation. Utility Model Content

[0004] To address the shortcomings of existing technologies, traditional methods of disassembling and assembling most cover plates are cumbersome and not convenient for automatic opening and closing. Traditional cover plates are mostly fastened with screws or nested with clips, requiring special tools (such as screwdrivers and wrenches) to disassemble them one by one, resulting in long operation times. This utility model proposes a dustproof cover for the air outlet of the air conditioning compartment in a grain depot.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a dustproof cover for the air outlet of a special air-conditioning compartment in a grain depot, including a connecting pipe, and a cover mechanism is provided on the surface of the connecting pipe.

[0006] The cover plate mechanism includes an installation component. The inner wall of the installation component is fitted onto the surface of the connecting pipe.

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0023] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0024] This application discloses a dustproof cover for the air outlet of a grain depot's dedicated air conditioning unit. (Refer to...) Figures 1 to 3 A dustproof cover for the air outlet of a grain depot’s air-conditioning compartment includes a connecting pipe 1, and a cover mechanism 2 is provided on the surface of the connecting pipe 1.

[0025] The cover mechanism 2 includes a mounting component 201. The inner wall of the mounting component 201 is fitted onto the surface of the connecting pipe 1. A limiting frame 202 is fixedly connected to the inner wall of the mounting component 201. One side of the limiting frame 202 is attached to one side of the connecting pipe 1. Two flaps 203 are provided on the inner side of the mounting component 201. A connecting shaft 204 is fixedly connected to one side of each flap 203. A bearing 205 is fixedly connected to the inner cavity of the mounting component 201. The surface of the connecting shaft 204 is fixedly connected to the inner wall of the inner ring of the bearing 205. The dustproof cover for the air outlet of the grain depot's special air-conditioning compartment connects the connecting pipe 1 to the air outlet of the air-conditioning compartment. The fixed connection pipe 1 can improve the efficiency of air intake and exchange. Two sets of flaps 203 are connected to the mounting part 201 through the connecting shaft 204. The flaps 203 can rotate and flip along the mounting part 201 through the bearing 205. The connection points of the flaps 203 are close to each other and flip relative to each other, so that the air volume is split and the air volume coverage efficiency is improved. The tilted flaps 203 can also increase the air volume speed. The cover plate mechanism 2 can be quickly connected to the connecting pipe 1 through the mounting part 201. The installation position of the mounting part 201 can be limited by the limiting frame 202 to ensure the convenience of disassembly and assembly of the cover plate mechanism 2.

[0026] Reference Figure 1 The inner cavity of the mounting component 201 is threaded with a fastening bolt 3. One end of the fastening bolt 3 abuts against one side of the connecting pipe 1. Through the fastening bolt 3, the fastening bolt 3 threadedly connected to the mounting component 201 can continuously rotate and abut against one side of the connecting pipe 1, thereby improving the firmness of the cover plate mechanism 2 after installation with fewer fastening bolts 3.

[0027] Reference Figure 4 An extension plate 4 is fixedly connected to one side of the mounting component 201. A slide rail 5 is fixedly connected to one side of the extension plate 4. A sliding seat 6 is slidably connected to the surface of the slide rail 5. A first connecting rod 7 is rotatably connected to the inner cavity of the sliding seat 6. There are two first connecting rods 7. The other end of each first connecting rod 7 is rotatably connected to a second connecting rod 8. The inner cavity of the second connecting rod 8 is fixedly connected to the surface of the connecting shaft 204. Through the provided sliding seat 6, the sliding seat 6 can be regarded as a transmission component of the flip plate 203. The extension plate 4 and the slide rail 5 provide the main support for the transmission component. The sliding seat 6 can slide along the slide rail 5. The first connecting rod 7 is inclined. When the sliding seat 6 slides to one side, it can push the first connecting rod 7. The other end of the sliding first connecting rod 7 can push the second connecting rod 8. Since the other end of the second connecting rod 8 is fixedly connected to the connecting shaft 204, the second connecting rod 8 is pushed by the first connecting rod 7 and at the same time, it drives the flip plate 203 to rotate.

[0028] Reference Figure 4 and Figure 5A mounting groove 9 is provided on one side of the sliding seat 6. A motor 10 is fixedly installed on the inner wall of the mounting groove 9. A gear 11 is fixedly connected to the output end of the motor 10. One side of the gear 11 is rotatably connected to the inner wall of the mounting groove 9. A toothed groove 12 is provided on one side of the slide rail 5. The tooth surface of the gear 11 meshes with the inner wall of the toothed groove 12. The motor 10 can be regarded as the driving source of the sliding seat 6. The motor 10 can drive the gear 11 to rotate. Since the tooth surface of the gear 11 meshes with the inner wall of the toothed groove 12, the rotation of the gear 11 can drive the sliding seat 6 to slide automatically along the slide rail 5.

[0029] Reference Figure 5 A cover plate 13 is fixedly connected to one side of the sliding seat 6. The motor 10 and gear 11 are both located inside the cover plate 13. Through the cover plate 13, the cover plate 13 can shield the motor 10 and gear 11 to a certain extent, play a certain protective role, and try to avoid the motor 10 and gear 11 being exposed to the outside for a long time and thus being damaged.

[0030] Reference Figure 5 A limiting plate 14 is fixedly connected to one side of the extension plate 4. One side of the limiting plate 14 abuts against one side of the sliding seat 6. Through the setting of the limiting plate 14, the limiting plate 14 can limit the farthest displacement distance of the sliding seat 6, so as to avoid the sliding seat 6 from separating from the slide rail 5 as much as possible.

[0031] Working principle: Connecting pipe 1 is fixedly connected to the air outlet of the air conditioning compartment, which improves the efficiency of air intake and exchange. Two sets of flaps 203 are connected to the mounting part 201 through connecting shaft 204, and the flaps 203 can rotate and flip along the mounting part 201 through bearing 205. The connection points of the flaps 203 are close to each other and flip relative to each other, which makes the air volume diverted and improves the air volume coverage efficiency. The tilted flaps 203 can also increase the air outlet speed. The cover mechanism 2 is quickly connected to the connecting pipe 1 through the mounting part 201. The installation position of the mounting part 201 can be limited by the limiting frame 202 to ensure the convenience of disassembly and assembly of the cover mechanism 2. The fastening bolt 3, which is threaded to the mounting part 201, can continuously rotate and connect with the connecting pipe. One side of 1 abuts against each other, thereby improving the firmness of the cover plate mechanism 2 after installation by using fewer fasteners 3. The motor 10 can drive the gear 11 to rotate. Since the tooth surface of the gear 11 meshes with the inner wall of the tooth groove 12, the rotation of the gear 11 can drive the sliding seat 6 to slide automatically along the slide rail 5. The first connecting rod 7 is inclined. When the sliding seat 6 slides to one side, it can push the first connecting rod 7. The other end of the sliding first connecting rod 7 can push the second connecting rod 8. Since the other end of the second connecting rod 8 is fixedly connected to the connecting shaft 204, the second connecting rod 8 is pushed by the first connecting rod 7 and drives the flip plate 203 to rotate. The limiting plate 14 can limit the farthest displacement distance of the sliding seat 6 to avoid the sliding seat 6 from disengaging from the slide rail 5 as much as possible.

[0032] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
