[0002] The field of transformer technology involves key equipment in power engineering, primarily used for the transmission and conversion of electrical energy. Transformers utilize the principle of electromagnetic induction to convert alternating current (AC) of one voltage level to another, enabling efficient power transmission and distribution.

[0003] Dustproof power transformers effectively resist the intrusion of dust, dirt, and other environmental pollutants, thereby improving equipment reliability and service life. These transformers typically employ a special structural design to ensure internal components are protected from external environmental influences, helping to reduce maintenance needs, lower operating costs, and adapt to constantly changing operating environments and demands.

[0004] In the process of realizing this utility model, the inventors discovered the following problems with the existing technology: 1. In the case of commonly used power transformers, dust and impurities from the outside world directly adhere to the surface of the heat dissipation holes during long-term use, making it difficult to disassemble, clean, maintain, and replace them conveniently. This can easily lead to the transformer being unable to dissipate heat properly, affecting the quality of operation and increasing the risk of accidents; 2. Commonly used power transformers are usually placed outdoors, making them susceptible to impacts and collisions from the external environment. It is not convenient to effectively protect the transformer body, which can easily lead to damage and destruction of internal components, resulting in poor practicality. Utility Model Content

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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figures 1 to 4 The present invention provides a technical solution: a dustproof power transformer, including a protective shell 1, a number of support legs 2 installed at the bottom of the protective shell 1, a top cover 3 installed at the top of the protective shell 1, a protective frame 4 installed at the top of the top cover 3, heat dissipation components 5 installed on both sides of the protective shell 1, and a protective component 6 installed at the bottom of the inner wall of the protective shell 1.

[0024] The heat dissipation assembly 5 includes a mounting cover 501 that is movably mounted on both sides of the protective shell 1. A cooling fan mechanism 502 is mounted at both ends on one side of the mounting cover 501. A sliding groove 503 is provided on the other side of the mounting cover 501. A movable frame 504 is slidably connected inside the sliding groove 503. A dust filter 505 is installed inside the movable frame 504. A handle 506 is installed on the side of the movable frame 504 away from the dust filter 505. Locking bolts 507 are installed at both ends of the movable frame 504.

[0025] The protective assembly 6 includes a shelf 601 movably mounted to the bottom of the inner wall of the protective shell 1. A first drive mechanism 602 is mounted on one side of the shelf 601. A first bidirectional screw 603 is driven on one side of the first drive mechanism 602. A movable plate 604 is connected to both ends of the surface of the first bidirectional screw 603. A slide rod 605 is slidably connected to one end of the movable plate 604 away from the first bidirectional screw 603. A plurality of damping rods 606 are mounted on one side of the movable plate 604. A mounting bracket 607 is mounted on one side of the damping rods 606. A second drive mechanism 608 is mounted at the bottom end of one side of the mounting bracket 607. A second bidirectional screw 609 is driven on one side of the second drive mechanism 608. A clamping plate 610 is connected to the surface of the second bidirectional screw 609. A rubber anti-slip pad 611 is mounted on one side of the clamping plate 610.

[0026] In this embodiment, as Figure 1 As shown, the legs 2 are symmetrically distributed about the horizontal center line of the protective shell 1. The symmetrical layout design allows the protective shell 1 to be subjected to external forces or placed on different planes more evenly. The symmetrical support of the legs 2 in the horizontal direction allows the pressure on the protective shell 1 to be distributed more evenly to each leg 2, thereby effectively avoiding deformation or damage to the protective shell 1 due to excessive local stress.

[0027] In this embodiment, as Figure 3 As shown, the movable plate 604 forms a sliding structure with the placement plate 601 through the slide rod 605. The design of the sliding structure can ensure that the movable plate 604 can move smoothly and stably relative to the slide rod 605, which helps to quickly adjust the required clamping distance of the movable plate 604 so as to effectively position and limit the transformer body.

[0028] In this embodiment, as Figure 3 As shown, the mounting bracket 607 forms a buffer structure with the damping rod 606 and the moving plate 604. The design of the buffer structure enables the transformer body to effectively absorb and disperse the impact force when it is subjected to external impact or collision through the cooperation of the damping rod 606 and the moving plate 604. This helps to reduce the impact on the inside of the transformer body and thus avoid damage to internal components caused by external impact or collision.

[0029] In this embodiment, as Figure 2 As shown, the dust filter 505 is connected to the movable frame 504 and the handle 506 to form a pull-out structure. The pull-out structure design allows the dust filter 505 to be easily and conveniently slid out by pulling the handle 506 on one side of the movable frame 504, which helps to quickly clean, maintain and replace the dust filter 505 in the future.

[0030] In this embodiment, as Figure 4As shown, the movable plate 604 forms a transmission structure with the first bidirectional screw 603 and the first drive mechanism 602. The improved design of the transmission structure enables the movable plates 604 at both ends to be automatically and flexibly controlled to make relative displacement through the action of the first drive mechanism 602, thereby driving the mounting frame 607 and the clamping plate 610 to be stably and reliably clamped and limited. At the same time, it can be adapted and adjusted for transformers of different specifications and sizes.

[0031] In this embodiment, as Figure 3 As shown, damping rods 606 are evenly and equidistantly distributed on one side of the moving plate 604. The evenly and equidistant distribution layout design ensures that the moving plate 604 can disperse the pressure when subjected to external force, and works with the damping rods 606 to buffer the load, effectively avoiding damage to the transformer body and internal components caused by excessive local stress.

[0032] The usage and advantages of this utility model: The dustproof power transformer operates as follows:

[0033] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, firstly, the operator opens the top cover 3 and places the transformer body to be operated on the surface of the placement plate 601 stably. Then, the first drive mechanism 602 is activated, which drives the mounting brackets 607 at both ends to move relative to each other and fit tightly against the transformer body, achieving the effect of clamping and positioning. Further, the second drive mechanism 608 is activated, which drives the clamping plates 610 on both sides to effectively limit and clamp the other two sides of the transformer body, which helps to achieve a good limiting and impact resistance effect on the transformer body. After the adjustment is completed, the top cover 3 is closed. During long-term use, when it is necessary to clean and maintain the heat dissipation and dust prevention components, the locking bolts 507 at both ends of the moving bracket 504 can be unlocked. Then, the handle 506 on one side of the moving bracket 504 is pulled to move the dust filter 505 smoothly and conveniently slide out, which can be quickly disassembled and cleaned, improving the dust prevention effect and heat dissipation quality.

[0034] 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 preferred examples and are not intended to limit the 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. The scope of protection of this utility model is defined by the appended claims and their equivalents.
