Description

Technical Field

[0001] The utility model relates to the technical field of power transformers, and specifically relates to an explosion-proof and sun-proof power transformer. Background Art

[0002] A transformer is a device that uses the principle of electromagnetic induction to change the AC voltage. Its main components are the primary coil, secondary coil, and iron core. However, most existing transformers are directly exposed to the outside and are constantly exposed to the sun, which easily causes the wires, rubber, and other spare parts in the transformer to age rapidly, reducing the practicality of the transformer. There have been patent documents that have improved this situation.

[0003] For example, in Chinese Patent CN212411742U, a sun-proof building transformer includes a transformer body. A horizontal plate is provided on the front side of the transformer body, and a clamping connection is provided on the inner wall of the horizontal plate, and the clamping connection is buckled on the transformer body. When the sun shines on the transformer body of the utility model, it is first blocked by the sunshade, and the white color is used to slow down the speed of heat accumulation. (Under the same other conditions, the temperature of a dark object changes faster, while that of a light object changes slower. Specifically, a black object changes the fastest and a white object changes the slowest). In this way, various components inside the transformer body are protected. When a large amount of heat accumulates inside the sunshade, the blower fan is started, and the blower fan is used to generate wind and blow away the heat, solving the problem that most existing transformers are directly exposed to the outside and are constantly exposed to the sun, which easily causes the wires, rubber, and other spare parts in the transformer to age rapidly.

[0004] Although the device in the above document uses a sunshade installed on the top of the transformer for sun protection, it still has obvious defects in actual use, such as:

[0005] Although this device adds a sunshade, when the transformer is in use, cables need to be installed and pulled on its top, resulting in the sunshade affecting the installation and use of the transformer, causing inconvenience to the staff. To solve such problems, the height of the sunshade needs to be increased. However, after the height is increased, the stability of the sunshade will decrease in windy weather and it is easily bent and damaged;

[0006] Therefore, a convenient-to-operate and highly stable explosion-proof and sun-proof power transformer is now designed to solve such defects. Summary of the Utility Model

[0007] In view of the deficiencies of the prior art, the utility model provides an explosion-proof and sun-proof power transformer, which solves the problems that the sunshade of the existing device is easy to affect the installation of the device and is easy to be damaged.

[0008] To achieve the above object, the utility model is realized by the following technical solutions: An explosion-proof and sun-proof power transformer, including a transformer, wherein annular cylinders and rectangular cylinders are respectively fixedly connected to both sides of the surface and the rear of the transformer, guide rods and rectangular frames are respectively slidably installed inside the annular cylinders and the rectangular cylinders, and a sunshade is fixedly connected between the tops of the guide rods and the rectangular frames.

[0009] Preferably, insertion slots which are used in cooperation are respectively opened on one side of the rectangular frame and the rectangular cylinder. A vertical plate is slidably installed inside the rectangular frame. An insertion block which is used in cooperation with the insertion slot is fixedly connected to one side of the vertical plate. A spring is fixedly connected between the inner wall of the vertical plate and the rectangular frame. Expansion slots are respectively opened on opposite sides of the two rectangular frames. Arc blocks which are used in cooperation with the expansion slots are respectively fixedly connected to opposite sides of the two vertical plates.

[0010] Preferably, a splicing port is opened on the surface of the sunshade. A sunshade board is arranged inside the splicing port. Arc abutting blocks which are used in cooperation with the arc blocks are respectively fixedly connected to both sides of the bottom of the sunshade board through brackets.

[0011] Preferably, guide pulleys which are used in cooperation are respectively fixedly connected to the tops of the sunshade and the sunshade board. Thread passing openings which are used in cooperation are respectively opened on the tops of the sunshade and the sunshade board.

Specific embodiments

[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0024] Please refer to Figure 1-6, the utility model provides a technical solution: an explosion-proof and sun-proof power transformer, including a transformer 1. On both sides of the surface and the rear of the transformer 1, an annular cylinder 2 and a rectangular cylinder 3 are respectively fixedly connected. A guide rod 4 and a rectangular frame 5 are respectively slidably installed inside the annular cylinder 2 and the rectangular cylinder 3. A sunshade 6 is fixedly connected between the tops of the guide rod 4 and the rectangular frame 5. Plug-in slots 7 that are used in cooperation with each other are respectively opened on one side of the rectangular frame 5 and the rectangular cylinder 3. A vertical plate 8 is slidably installed inside the rectangular frame 5. A plug-in block 9 that is used in cooperation with the plug-in slot 7 is fixedly connected to one side of the vertical plate 8. A spring 10 is fixedly connected between the inner wall of the vertical plate 8 and the rectangular frame 5. Telescopic slots 11 are respectively opened on the opposite sides of the two rectangular frames 5. Arc blocks 12 that are used in cooperation with the telescopic slots 11 are respectively fixedly connected to the opposite sides of the two vertical plates 8. A splicing port 13 is opened on the surface of the sunshade 6. There is a margin inside the splicing port 13, which can prevent the sunshade plate 14 from falling and flipping. A sunshade plate 14 is arranged inside the splicing port 13. Arc abutting blocks 15 that are used in cooperation with the arc blocks 12 are respectively fixedly connected to both sides of the bottom of the sunshade plate 14 through brackets. Guide pulleys 16 that are used in cooperation with each other are respectively fixedly connected to the tops of the sunshade 6 and the sunshade plate 14. Threading ports 17 that are used in cooperation with each other are respectively opened on the tops of the sunshade 6 and the sunshade plate 14.

[0025] When in use, first install the sunshade 6 on the top of the transformer 1, insert the guide rod 4 and the rectangular frame 5 into the inside of the annular cylinder 2 and the rectangular cylinder 3 respectively, and then pass the cable of the transformer 1 through the splicing port 13 from the top. Then adjust the height of the sunshade 6. After the adjustment is completed, insert the sunshade plate 14 into the splicing port 13, and make the threading ports 17 on both sides face each other to wrap the cable. At the same time, the two guide pulleys 16 clamp and guide the cable. When the sunshade plate 14 is inserted into the splicing port 13, the arc abutting blocks 15 at the bottom will squeeze the arc blocks 12 to push the vertical plate 8 to move to one side, so that the plug-in block 9 is inserted into the inside of the plug-in slot 7. At this time, the whole sunshade 6 is fixed through the rectangular frame 5 and the guide rod 4.

[0026] Furthermore, threaded cylinders 18 are respectively fixedly connected to both sides of the tops of the sunshade 6 and the sunshade plate 14. A threaded bolt 19 is threadedly connected inside the threaded cylinder 18.

[0027] Insert the threaded bolt 19 into the threaded cylinders 18 at the tops of the sunshade 6 and the sunshade plate 14 to fix the sunshade plate 14. The sunshade 6 can block the sunlight from shining on the transformer 1. At the same time, since the distance between the sunshade 6 and the transformer 1 increases after the sunshade 6 is raised, it is convenient for the transformer 1 to dissipate heat. When it is raining or windy, lower the sunshade 6 through the rectangular cylinder 3 and the rectangular frame 5, reduce the height of the sunshade 6 to increase its own stability, and avoid damage caused by the wind.

[0028] At the same time, the content not described in detail in this specification belongs to the prior art well-known to those skilled in the art.
