Technical Field
[0001] This utility model relates to the field of inverter cabinet technology, and in particular to an inverter cabinet. Background Technology
[0002] Inverter cabinets, also known as grid-connected cabinets, are important equipment in power systems, playing a key role, especially in renewable energy fields such as photovoltaic power generation and wind power generation.
[0003] As disclosed in publication number CN220985543U, a photovoltaic inverter cabinet includes a cabinet body and a dust filter. A cabinet door is movably connected to the front of the cabinet body. A dust collection box is located in the middle of the left side of the cabinet body. A fan is installed at the bottom of the dust collection box, and a dust filter is installed inside the dust collection box. A rigid pipe connects to the top of the dust collection box. This photovoltaic inverter cabinet, by incorporating a fan, generates suction force, which is then directed through the rigid pipe, corrugated pipe, and dust collection hood to the interior of the cabinet to remove dust from the photovoltaic inverter installed inside. This reduces the accumulation of dust on the surface of the photovoltaic inverter. Furthermore, by incorporating a servo motor, a threaded rod can be driven to rotate, causing the threaded rod to move the dust collection hood linearly within the cabinet's interior through the action of a threaded sleeve. This increases the suction range and improves the dust removal effect, solving the problem of inconvenient dust removal of the photovoltaic inverter.
[0004] This patented technology utilizes a fan to generate suction, which is then directed through rigid pipes, corrugated pipes, and a dust collection hood to remove dust from the photovoltaic inverters installed inside the cabinet. However, as a critical piece of equipment in the power system, the inverter cabinet requires regular inspection and maintenance to ensure power conversion efficiency and operational safety. In practice, the cabinet door is easily damaged by accidental impacts from external factors, causing it to close suddenly. This not only disrupts the continuity of maintenance work and increases the difficulty of operation, but also poses a serious threat to personnel safety, potentially causing serious electric shock accidents due to the sudden closure of the door, such as pinching workers or accidentally touching live parts. Therefore, we propose a novel inverter cabinet. Utility Model Content
[0005] The purpose of this invention is to solve the problem that in the existing technology, during the maintenance of inverter cabinets, the cabinet door is easily closed suddenly by accidental collisions from external factors. This not only interrupts the continuity of maintenance work and increases the difficulty of operation, but may also cause serious electric shock accidents due to the sudden closure of the door, such as pinching the workers or accidentally touching live parts, posing a serious threat to personnel safety.
[0006] To achieve the above objectives, the present invention adopts the following technical solution: an inverter cabinet, comprising a cabinet body, a hinge connected to one front surface of the cabinet body, a cabinet door connected to the surface of the hinge, a fixing component provided on the inner wall of the cabinet body near the hinge, the fixing component comprising a fixing box, a connecting box connected to the front surface of the fixing box, two sets of first springs connected inside the fixing box, sliders connected to the front surfaces of the two sets of first springs, two sets of second springs connected inside the connecting box, insert rods inserted into the two sets of second springs, push plates connected to the surfaces of the two sets of insert rods, handles connected to the rear ends of the two sets of insert rods, and two sets of insertion holes opened on the outer surface of the slider near the insert rods.
[0007] Furthermore, the outer surface of the slider is in contact with the inner wall of the fixing box, and a sliding connection is formed between the slider and the fixing box.
[0008] Furthermore, the first spring and the slider form an elastic structure, and the position and size of the insertion rod match the position and size of the two sets of insertion holes.
[0009] Furthermore, a drying assembly is connected to the bottom surface of the cabinet, the drying assembly including a drying chamber, and magnetic blocks are embedded in the inner walls on both sides of the drying chamber.
[0010] Furthermore, the drying oven is equipped with a drying box inside, and magnets are connected to both outer surfaces of the drying box.
[0011] Furthermore, a humidity sensor is installed on the inner wall of the cabinet near the drying chamber, and the humidity sensor is electrically connected to an external power source.
[0012] Furthermore, the position and size of the magnetic block match the position and size of the magnet, and the magnet and the magnetic block form a magnetic connection.

[0022] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.
[0023] 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. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.
[0024] Example 1, as Figure 1 - Figure 4As shown, this utility model provides an inverter cabinet, including a cabinet body. A hinge 2 is connected to the front surface of one side of the cabinet body 1, and a cabinet door 3 is connected to the surface of the hinge 2. A fixing component 4 is provided on the inner wall of the cabinet body 1 near the hinge 2. The fixing component 4 includes a fixing box 401, a connecting box 402 is connected to the front surface of the fixing box 401, and two sets of first springs 403 are connected inside the fixing box 401. A slider 404 is connected to the front surface of the two sets of first springs 403. Two sets of second springs 405 are connected inside the connecting box 402. Two springs 405 have insert rods 407 inserted inside. Push plates 406 are connected to the surfaces of the two sets of insert rods 407. Handles 408 are connected to the rear ends of the two sets of insert rods 407. Two sets of insertion holes 409 are opened on the outer surface of the slider 404 near the insert rods 407. The outer surface of the slider 404 is in contact with the inner wall of the fixed box 401. The slider 404 and the fixed box 401 form a sliding connection. The first spring 403 and the slider 404 form an elastic structure. The position and size of the insert rods 407 match the position and size of the two sets of insertion holes 409.
[0025] The overall effect of Embodiment 1 is that, during the inspection and maintenance of the cabinet 1, the cabinet door 3 can be opened first via the hinge 2, and then the handle 408 can be pulled outwards. This allows the handle 408 to drive the push plate 406 via the insert rod 407 to compress the second spring 405, and the front end of the insert rod 407 can be pulled out from the first set of insertion holes 409. Then, the first spring 403 will push the slider 404 with its own elasticity, causing the slider 404 to pop out and limit the cabinet door 3. At this time, the handle 408 can be released, allowing the second spring 405 to push the push plate 406 with its own elasticity, causing the front end of the insert rod 407 to insert into the second set of insertion holes 409, thus fixing the slider 404. When inspecting the cabinet 1... After completion, the handle 408 can be pulled outward again to allow the front end of the insertion rod 407 to be pulled out from the second set of insertion holes 409. Then, the slider 404 is pushed into the fixing box 401 to compress the first spring 403. When the slider 404 is fully pushed into the fixing box 401, the handle 408 is released, allowing the insertion rod 407 to be inserted into the first set of insertion holes 409 under the elastic force of the second spring 405 for fixing. At this point, the cabinet door 3 can be closed by the hinge 2. By moving the slider 404 in this way, the problem of the cabinet door 3 being pinched and injured by external influences or accidentally touching live parts during maintenance can be avoided, thus improving the safety of operators when maintaining the cabinet 1.
[0026] Example 2, as Figure 1 and Figure 5As shown, a drying assembly 5 is connected to the bottom surface of the cabinet 1. The drying assembly 5 includes a drying chamber 501. Magnetic blocks 502 are embedded in the inner walls of both sides of the drying chamber 501. A drying box 503 is installed inside the drying chamber 501. Magnets 504 are connected to the outer surfaces of both sides of the drying box 503. A humidity sensor 505 is installed on the inner wall of the cabinet 1 near the drying chamber 501. The humidity sensor 505 is electrically connected to an external power source. The position and size of the magnetic blocks 502 match the position and size of the magnets 504. A magnetic connection is formed between the magnets 504 and the magnetic blocks 502.
[0027] The effect achieved by the entire embodiment 2 is that when the cabinet door 3 is opened, the drying box 503 can be pulled out from the drying box 501, and then the prepared drying package is placed in the drying box 503. The drying box 503 is then pushed into the drying box 501, so that the magnetic block 502 and the magnet 504 can be magnetically attracted and fixed. In addition, a humidity sensor 505 is provided to observe the dryness and humidity of the internal air at regular intervals, effectively reducing the humidity level inside the inverter cabinet 1 and providing a dry operating environment for the electrical equipment inside the inverter cabinet 1.
[0028] Working principle: When inspecting and maintaining the inside of cabinet 1, cabinet door 3 can be opened and then fixed by moving slider 404. This prevents the cabinet door 3 from closing due to external influences during maintenance, which could pinch workers or cause accidental contact with live parts, thus improving the safety of operators when maintaining cabinet 1. The drying pack in drying box 503 can dry the air inside cabinet 1 and absorb moisture from the air, effectively reducing the humidity level inside inverter cabinet 1 and providing a dry operating environment for the electrical equipment inside inverter cabinet 1.
[0029] The above are merely preferred embodiments of this utility model and are not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from the technical solution of this utility model shall still fall within the protection scope of this utility model.
