[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 protection scope of the present utility model.

[0023] Please see Figures 1 to 2 In this embodiment, an external maintenance fan cover for a transformer substation includes a fan cover body 1. The front of the fan cover body 1 is provided with a filter assembly 2 that can stably filter dust. The front of the fan cover body 1 is provided with multiple stabilizing components 3 for connecting the filter assembly 2 and the fan cover body 1. Ear plates 4 are fixed to the outer side of the fan cover body 1. Using the ear plates 4 and corresponding fasteners such as bolts and nuts, the fan cover body 1 is firmly fixed to other support structures to ensure that the fan cover is installed stably and will not loosen due to vibration or external force. Filter cotton 6 is provided on the inner side of the filter assembly 2.

[0024] In addition, the filter assembly 2 includes a protective plate 201 that abuts against the front of the fan cover body 1. Multiple hinges 203 are fixed on the front of the protective plate 201 and at its lower position. The multiple hinges 203 serve as a connection. When the stabilizing component 3 is disconnected from the filter assembly 2, the hinges 203 can provide support. The inner sides of the multiple hinges 203 are fixed to the bottom of the fan cover body 1. The outer periphery of the filter cotton 6 is coated with glue. When using the filter cotton 6, it needs to be cut to a suitable size. After applying glue to its outer periphery, it is adhered to the inner side of the protective plate 201 to ensure that the filter cotton 6 and the protective plate 201 are tightly fitted without any obvious gaps. This structure can ensure that the adhesion area between the filter cotton 6 and the protective plate 201 is not too large, and that the gas must pass through the filter cotton 6. The filter cotton 6 is adhered to the protective plate 201 by glue.

[0025] In this embodiment, the filter component 2 and the filter cotton 6 work together to ensure both good filtration effect and good connection stability. Furthermore, it is convenient to replace the filter cotton 6 in the future, as it only requires tearing off the glue around the outer periphery of the filter cotton 6.

[0026] Please refer to it again. Figure 1 and Figure 3To facilitate subsequent maintenance, in this embodiment, each stabilizing component 3 includes two support plates 301 fixed to the front of the fan cover body 1. The two support plates 301 provide support. A hinge shaft 302 is fixed on the opposite side of each pair of support plates 301. A hinge joint 303 is hinged to the outer surface of each hinge shaft 302. A hinge bolt 305 is fixed to the side of the hinge joint 303 near the filter assembly 2. The hinge bolt 305 and the wing nut 306 cooperate. When it is necessary to open the filter assembly 2, simply unscrew the wing nut 306. When it is necessary to fix the filter assembly 2, simply screw the wing nut 306 until it abuts against the fixed bending plate 304. The wing nut 306 is threaded onto the outer surface of the hinge bolt 305. Each stabilizing component 3 also includes a fixed bending plate 304 fixed to the top of the filter assembly 2.

[0027] In addition, the front side of the fan cover body 1 is inclined, which can reduce the probability of rainwater flowing into the fan cover body 1. Each support plate 301 is fixed to the inclined part of the front side wall of the fan cover body 1, the bottom of each fixed bending plate 304 is fixed to the top of the protective plate 201, and multiple wing nuts 306 are fixed to the fixed bending plate 304.

[0028] It should be further explained that each fixed bend plate 304 has a clearance groove at its top, and multiple hinge bolts 305 pass through multiple clearance grooves respectively. Each fixed bend plate 304 has a drainage hole at its bottom. During use, if it rains, rainwater that may enter the fan cover body 1 can be drained away through the drainage hole, preventing rainwater from flowing into the fan cover body 1 at the fixed bend plate 304, thereby avoiding equipment damage caused by moisture and extending the service life of the fan cover.

[0029] In addition, an inner plate 5 is fixed to the inner bottom wall of the fan cover body 1. Multiple threaded holes are provided on the inner plate 5. The design of the inner plate 5 can provide installation positions for other components inside the fan cover body 1, and also enhance the structural strength of the fan cover body 1. The rear side of the fan cover body 1 is open, and a flow hole is provided on the front side of the fan cover body 1. The flow hole is compatible with the filter cotton 6.

[0030] In this embodiment, the rear side of the fan cover body 1 is open, the front side is provided with a flow hole, and the front side is inclined. This structural design not only facilitates air circulation, but also prevents rainwater from directly entering the interior of the fan cover body 1 to a certain extent.

[0031] Understandably, the ear plate 4 is also provided with multiple threaded holes. The threaded holes help the ear plate 4 to be smoothly fixed to the fixed structure. This device can effectively filter the air entering the fan, prevent dust and impurities from damaging the fan, and at the same time has convenient maintenance and good drainage function, ensuring that the fan can operate stably under various environmental conditions.

[0032] The working principle of the above embodiments is as follows:

[0033] Air enters the fan housing body 1 through these filter holes 202. Since the filter assembly 2 is installed on the front of the fan housing body 1, the air passes through the filter assembly 2 before entering the fan housing body 1. When the air passes through the filter cotton 6, dust, impurities, etc. are intercepted by the filter cotton 6, thereby purifying the air. The filtered clean air enters the fan housing, providing a good working environment for the fan. When it is necessary to replace or clean the filter cotton 6, simply loosen the wing nut 306 and remove the filter assembly 2 from the fixing assembly 3 using the hinge bolt 305. The filter assembly 2 is connected to the bottom of the fan housing body 1 by the hinge 203. The design of the hinge 203 allows the filter assembly 2 to be easily flipped and disassembled. After replacement or cleaning, the filter assembly 2 is reinstalled on the fixing assembly 3 and tightened with the wing nut 306 to complete the maintenance operation.

[0034] It should be noted that, in this document, relational terms such as "first" and "second" are used merely to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus.
