[0024] To make the above-mentioned objectives, features and advantages of this utility model more readily understood, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.
[0025] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.
[0026] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single embodiment or an embodiment selectively excluded from other embodiments.
[0027] Example 1:
[0028] Please see Figures 1-2 This is the first embodiment of the present invention.
[0029] This embodiment provides a modular box-type high-voltage AC metal-enclosed switchgear, including:
[0030] An unfolding mechanism 3 is provided inside the box 1, a circulation mechanism 4 is provided on the side of the box 1, and a drying mechanism 5 is provided inside the circulation mechanism 4.
[0031] The unfolding mechanism 3 includes side plates 31 symmetrically rotated and installed on both sides of the box body 1. Partitions 2 are evenly fixed inside the box body 1. Limiting seats 32 are fixed at the top of the inner side of the partitions 2. Limiting slots 33 are opened on the top side of the limiting seats 32. A fixing plate 34 is fixed at one end of the bottom side of the partitions 2. A lead screw 35 is rotatably installed between the fixing plate 34 and one end of the inner side of the box body 1. Servo motors 36 are evenly fixed on the side of the box body 1. A straight plate 37 is installed on the lead screw 35. Slider blocks 38 are fixed on the inner sides of both ends of the straight plate 37.
[0032] Specifically, a movable door 6 is mounted on the side of the housing 1 via a hinge, a slider 38 is slidably mounted inside the limit groove 33, a straight plate 37 is slidably mounted on the bottom side of the partition 2, and the output end of the servo motor 36 passes through the housing 1 and is fixedly connected to the lead screw 35.
[0033] Furthermore, by using the servo motor 36 in conjunction with the lead screw 35, the side panel 31 can be automatically opened when maintenance of the inside of the housing 1 is required, making it convenient for operators to perform maintenance operations.
[0034] When in use, pull the movable door 6 to open it. At this time, the servo motor 36 can be controlled to drive the output end screw 35 to rotate, thereby pushing the straight plate 37 to move along the direction of the screw 35. At this time, the slider 38 slides inside the limit groove 33, thereby pushing the limit seat 32, which drives the side plate 31 to rotate around one end of the side plate 31, thereby unfolding the two side plates 31. At this time, it is convenient for the operator to maintain the components inside the box 1, making it convenient for the operator to use.
[0035] In summary, through the structure of the unfolding mechanism 3, the inner side of the equipment is divided into multiple areas by the partition 2. The straight plate 37 is controlled by the servo motor 36 to move along the lead screw 35, thereby pushing the limit seat 32 to drive the side plate 31 to unfold. This exposes the internal components of the housing 1 to the external environment, making it easier for operators to maintain the internal components and making the equipment more convenient to use.
[0036] Example 2:
[0037] Please see Figures 3-4 This is the second embodiment of the present utility model.
[0038] Specifically, the circulation mechanism 4 includes an exhaust port 41 opened at one end of the side of the housing 1, a hollow shell 42 fastened to the side of the exhaust port 41, an air inlet port 43 opened at the other end of the side of the housing 1, a cylinder 44 fastened to the side of the air inlet port 43, an air pump 45 fixedly installed at the center of the side of the housing 1, an input pipe 46 fixedly installed at the input end of the air pump 45, an output pipe 47 fixedly installed at the output end of the air pump 45, one end of the input pipe 46 is connected to the inside of the hollow shell 42, and one end of the output pipe 47 is connected to the inside of the cylinder 44.
[0039] Furthermore, the air pump 45, in conjunction with the exhaust port 41 and the air inlet port 43, drives the air circulation inside the box 1 to prevent heat accumulation inside the box 1, and in conjunction with the hollow shell 42, dissipates the heat to the outside air.
[0040] Specifically, the drying mechanism 5 includes a filter cylinder 51 that is slidably installed inside the cylinder 44. A desiccant is placed inside the filter cylinder 51. A top cover 52 is fixed to the top of the filter cylinder 51. A handle 53 is fixed to the center of the top of the top cover 52. Elastic blocks 54 are symmetrically fixed on both sides of the cylinder 44. The elastic blocks 54 are snapped onto both ends of the top cover 52.
[0041] Furthermore, the structure of the filter cartridge 51 allows water vapor in the air inside the housing 1 to be removed when the air passes through the filter cartridge 51, ensuring that the environment inside the housing 1 is dry.
[0042] In use, the air pump 45 is controlled to draw out the air inside the hollow shell 42, thereby expelling the air inside the box 1 through the exhaust port 41. With the cooperation of the input pipe 46 and the output pipe 47, the air is delivered to the inside of the cylinder 44. When it passes through the filter cylinder 51, the water vapor in the air is removed. Then, the dry air is delivered back to the inside of the box 1 through the air inlet 43 to ensure that the environment inside the box 1 is dry.
[0043] In summary, through the structure of the circulation mechanism 4 and the drying mechanism 5, the air is circulated by the air pump 45, so that when the air passes through the filter cartridge 51, it adsorbs water vapor in the air, ensuring that the environment inside the box 1 is dry and preventing short circuit damage to the electronic components inside.
