Description

Technical Field

[0001] This utility model relates to the field of air-cooled electrical cabinet technology, and in particular to the modular adjustable air duct of air-cooled electrical cabinet. Background Technology

[0002] Air-cooled electrical cabinets are electrical equipment protection cabinets that use natural air convection or forced air supply from fans to dissipate the heat generated by the circuit breakers and frequency converters during operation, in order to prevent overheating of the equipment and ensure the stable and reliable operation of the electrical system.

[0003] Modular adjustable air ducts in air-cooled electrical cabinets are heat dissipation components that adopt a combinable modular structure and can flexibly adjust the air duct path or airflow distribution according to the heat differences of different electrical components inside the cabinet. They can precisely guide cooling airflow to adapt to heat-generating parts, optimize heat dissipation efficiency, and are easy to maintain and adapt to various operating conditions. However, the modular design relies on the splicing of multiple modules. Although gaskets and clamps are used for connection, vibration and temperature cycling during long-term operation can cause the sealing material to age and the interface to loosen, resulting in local air leakage, significantly reducing the effective airflow and causing a decrease in heat dissipation efficiency. In existing technologies, miniature pressure sensors are embedded in key nodes of the labyrinth seal to monitor the pressure difference inside and outside the interface in real time. When the pressure difference drops below a certain value, the cabinet controller is triggered to alarm and prompt maintenance. However, in existing technologies, the air duct needs to be disassembled by unscrewing each screw one by one, which takes a long time when maintenance is needed, thus reducing work efficiency. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a modular adjustable air duct for an air-cooled electrical cabinet, aiming to improve the problem that in the prior art, each screw needs to be unscrewed one by one when the air duct is disassembled, which takes a long time when maintenance is needed, resulting in reduced work efficiency.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a modular adjustable air duct for an air-cooled electrical cabinet, including a cabinet body. A disassembly mechanism is installed on the top inner side of the cabinet body for disassembling the pipes. A folding mechanism is installed on the inner side of the cabinet body for folding the pipes. The disassembly mechanism includes a fixed frame, which is fixedly connected to the rear inner top of the cabinet body. Connecting pipes are slidably connected to the left and right sides of the fixed frame. A threaded rod is rotatably connected to the front side of the fixed frame. A movable square plate is threadedly connected to the outer side of the threaded rod. Rotating short columns are rotatably connected to the left and right ends of the movable square plate. Connecting plates are rotatably connected to the opposite sides of the two rotating short columns. Connecting short columns are rotatably connected to the rear sides of the two connecting plates. The rear side of the connecting short columns is rotatably connected to the front side of the connecting pipes. A second drive assembly is installed on the front side of the threaded rod.

[0006] As a further description of the above technical solution: The second drive assembly includes a rotating rod, the rear side of which is fixedly connected to the middle of the front side of the threaded rod, and a turntable is fixedly connected to the front side of the rotating rod.

[0007] As a further description of the above technical solution: The folding mechanism includes a connecting rod rotatably connected to the middle of the inner top of the cabinet. Gears are fixedly connected to both the left and right ends of the connecting rod. Racks are slidably connected to both the left and right ends of the inner top of the cabinet. A fixed square rod is fixedly connected to the rear side of the rack. The top of the rack meshes with the bottom of the gear. A fixed circular plate is fixedly connected to the left side of the connecting rod. Rotating cylinders are rotatably connected to the upper and lower ends of the middle of the connecting pipe. Sliding grooves are provided on both the left and right ends of the top of the cabinet. A connecting rod is fixedly connected to the front side of the rack. The outer side of the connecting rod slidably connects with the inner side of the sliding groove. A first drive assembly is installed on the right side of the fixed circular plate.

[0008] As a further description of the above technical solution: The first drive assembly includes a connecting rod, which is fixedly connected to the right end of the fixed circular plate, and an anti-slip sleeve is installed on the outer side of the connecting rod.

[0009] As a further description of the above technical solution: A locking bend is provided on the top right side of the cabinet, and the middle part of the locking bend engages with the outer side of the anti-slip sleeve.

[0010] As a further description of the above technical solution: The cabinet is rotatably connected to the left and right ends of the front side, and heat dissipation grooves are equidistantly opened on the bottom rear side of the cabinet.

[0012] As a further description of the above technical solution: Multiple hinge plates are fixedly connected at equal intervals on the front side of the cabinet, and screws are threaded onto the outer side of each hinge plate.

[0013] This utility model has the following beneficial effects: 1. In this utility model, the rotating turntable causes the threaded rod to rotate in front of the fixed frame. When the threaded rod rotates, the movable square plate on its outer side moves accordingly. The rotating short columns at the left and right ends of the movable square plate move with it, thereby driving the connecting plate to move. The connecting short column on the rear side of the connecting plate moves accordingly. Since the rear side of the connecting short column is rotatably connected to the front side of the connecting pipe, the connecting pipe slides and unfolds on the left and right sides of the fixed frame, achieving a quick disassembly effect and thus improving work efficiency.

[0014] 2. In this utility model, the operating connecting rod is prevented from slipping out of the hand by the installation of the anti-slip sleeve, which in turn drives the fixed circular plate to rotate, thereby causing the connecting circular rod to rotate.

The connecting rod slides along the sliding groove, and the fixed square rod moves synchronously. Since the fixed square rod is installed on the rear side of the connecting pipe, it cooperates with the rotating cylinders at the upper and lower ends of the connecting pipe to realize the folding of the pipe.

[0021] 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 protection scope of the present utility model.

[0022] Reference Figure 1 , Figure 2 and Figure 4 This utility model provides an embodiment of a modular adjustable air duct for an air-cooled electrical cabinet, including a cabinet body 1. A disassembly mechanism 3 is installed on the top inner side of the cabinet body 1 for disassembling the pipes. A folding mechanism 2 is installed on the inner side of the cabinet body 1 for folding the pipes. The disassembly mechanism 3 includes a fixed frame 306, which is fixedly connected to the rear inner top of the cabinet body 1. Connecting pipes 301 are slidably connected to both the left and right sides of the fixed frame 306. A threaded rod 302 is rotatably connected to the front side of the fixed frame 306. A movable square plate 304 is threadedly connected to the outer side of the threaded rod 302, allowing the movable square plate 304 to move. Rotating short columns 307 are rotatably connected to both the left and right ends of the movable square plate 304. Connecting plates 303 are rotatably connected to the opposite sides of the two rotating short columns 307. Connecting short columns 308 are rotatably connected to the rear sides of the two connecting plates 303. The rear side of the connecting short columns 308 is rotatably connected to the front side of the connecting pipe 301. A second drive assembly 305 is installed on the front side of the threaded rod 302. The second drive assembly 305 includes a rotating round rod 3051. The rear side of the rotating round rod 3051 is fixedly connected to the middle of the front side of the threaded rod 302. A turntable 3052 is fixedly connected to the front side of the rotating round rod 3051. The installation of the turntable 3052 facilitates the rotation of the threaded rod 302. Specifically, when it is necessary to disassemble the connecting pipe 301, the rotating turntable 3052 drives the rotating round rod 3051, thereby causing the threaded rod 302 to rotate in front of the fixed frame 306. As the threaded rod 302 rotates, the movable square plate 304 on its outer side moves accordingly, and the rotating short column 307 at the left and right ends of the movable square plate 304 also moves accordingly, further driving the connecting plate 303 on the side away from the rotating short column 307 to move. The connecting short column 308 on the rear side of the connecting plate 303 also moves accordingly. Since there is a rotating connection between the rear side of the connecting short column 308 and the front side of the connecting pipe 301, the connecting pipe 301 slides and unfolds on the left and right sides of the fixed frame 306, thereby achieving the effect of quick disassembly.

[0023] Reference Figure 1 , Figure 3 and Figure 5The folding mechanism 2 includes a connecting rod 205, which is rotatably connected to the middle of the top inner side of the cabinet 1. Gears 202 are fixedly connected to both the left and right ends of the connecting rod 205. A rack 203 is slidably connected to both the left and right ends of the top inner side of the cabinet 1. A fixed square rod 206 is fixedly connected to the rear side of the rack 203. The top of the rack 203 meshes with the bottom of the gear 202. A fixed circular plate 207 is fixedly connected to the left side of the connecting rod 205. A rotating cylinder 209 is rotatably connected to both the upper and lower ends of the middle section of the connecting pipe 301. Sliding grooves 201 are provided on both the left and right ends of the top of the cabinet 1. A connecting rod 204 is fixedly connected to the front side of 203. The outer side of the connecting rod 204 is slidably connected to the inner side of the sliding groove 201. A first drive assembly 208 is installed on the right side of the fixed circular plate 207. The first drive assembly 208 includes a connecting bent rod 2081. The connecting bent rod 2081 is fixedly connected to the right end of the fixed circular plate 207. An anti-slip sleeve 2082 is installed on the outer side of the connecting bent rod 2081. A locking bent rod 8 is provided on the top right side of the cabinet 1. The middle part of the locking bent rod 8 is locked with the outer side of the anti-slip sleeve 2082. By installing the locking bent rod 8, unnecessary rotation of the connecting bent rod 2081 is avoided. Specifically, the connecting rod 2081 is operated, and the anti-slip sleeve 2082 is installed to prevent the connecting rod 2081 from slipping out of the hand. This causes the fixed circular plate 207 to rotate, which in turn causes the connecting rod 205 to rotate. The gears 202 at the left and right ends of the connecting rod 205 rotate with it. Since the gears 202 mesh with the rack 203, the rack 203 slides on the top inside the cabinet 1. At the same time, the connecting rod 204 moves along the sliding groove 201, and the fixed square rod 206 also moves in sync. Since the fixed square rod 206 is installed on the rear side of the connecting pipe 301 and works with the rotating cylinders 209 at the upper and lower ends of the connecting pipe 301, the pipe folding effect is achieved.

[0024] Reference Figure 1 , Figure 2 and Figure 3 Cabinet doors 4 are rotatably connected to the left and right ends of the front side of cabinet 1. Ventilation slots 10 are provided at equal intervals on the bottom rear side of cabinet 1. Fixed cylinders 9 are fixedly connected to the upper and lower ends of the middle front side of cabinet doors 4. Door handles 5 are fixedly connected to the front side of fixed cylinders 9. Multiple hinge plates 6 are fixedly connected at equal intervals on the front side of cabinet 1. Screws 7 are threadedly connected to the outer side of hinge plates 6. Specifically, the heat dissipation effect of the device is improved by opening the heat dissipation slot 10, the cabinet door 4 can be opened and closed by installing the door handle 5, and the cabinet door 4 can be securely installed by installing the screws 7.

[0025] Working principle: When it is necessary to disassemble the connecting pipe 301, the rotating turntable 3052 can drive the rotating round rod 3051, which in turn causes the threaded rod 302 to rotate in front of the fixed frame 306. When the threaded rod 302 rotates, the movable square plate 304 on its outer side moves accordingly. The rotating short column 307 at the left and right ends of the movable square plate 304 moves with it, which in turn drives the connecting plate 303 on the side away from the rotating short column 307 to move. The connecting short column 308 on the rear side of the connecting plate 303 moves accordingly. Since the rear side of the connecting short column 308 is rotatably connected to the front side of the connecting pipe 301, the connecting pipe 301 slides and unfolds on the left and right sides of the fixed frame 306, achieving the effect of quick disassembly. Operating the connecting rod 2081, the installation of the anti-slip sleeve 2082 prevents the connecting rod 2081 from slipping out of your hand, thereby driving the fixed circular plate 207 to rotate, which in turn causes the connecting rod 205 to rotate. The gears 202 at the left and right ends of the connecting rod 205 rotate with it. Because the gears 202 mesh with the rack 203, the rack 203 slides on the top inside the cabinet 1. The connecting rod 204 slides along the sliding groove 201, and the fixed square rod 206 moves synchronously. Since the fixed square rod 206 is installed on the rear side of the connecting pipe 301, it works with the rotating cylinders 209 at the upper and lower ends of the connecting pipe 301 to achieve the folding of the pipe.
