Description

Technical Field

[0001] This invention relates to the field of power transformers, and more specifically to a power transformer. Background Technology

[0002] Transformers are fundamental equipment for power transmission and distribution, widely used in industry, agriculture, transportation, and urban communities. There are approximately 17 million transformers in operation in my country, with a total capacity of about 11 billion kilovolt-amperes. Transformer losses account for about 40% of power transmission and distribution losses, indicating significant energy-saving potential. To accelerate the promotion and application of high-efficiency and energy-saving transformers, improve energy resource utilization efficiency, and promote green, low-carbon, and high-quality development, existing power transformer technologies, such as the one described in application number 202111300990.7, allow for short-distance movement of the transformer body. However, this is not suitable for the stable installation of transformers between utility poles with varying spacing. Summary of the Invention

[0003] The purpose of this invention is to provide a power transformer that allows the transformer to be stably installed between utility poles with different spacing.

[0004] The objective of this invention is achieved through the following technical solution: a power transformer, comprising a transformer and a bottom frame fixedly connected to the lower side of the transformer, wherein two clamping seats are slidably connected to the front and rear sides of the bottom frame, and each pair of clamping seats is mirror-arranged between each other, and each pair of clamping seats is rotatably connected to the left and right sides by a bolt.

[0005] Each of the four corners of the bottom frame is provided with an opening slot.

[0006] The inner side of each clamp is an arc-shaped surface.

[0007] The curved surface of each clamping seat is roughened.

[0008] Each of the clamping seats has a scraper slidably connected to its upper side, and each scraper has an elongated hole in the middle. Attached Figure Description

[0018] This section is based on Figure 1-8 The working process described is as follows: To facilitate the stable installation of the transformer between utility poles of varying spacing, during use, a bottom frame 102 is welded and fixedly connected to the underside of the transformer 101. Two mirror-image clamping seats 201 are rotatably connected to the front and rear sides of the bottom frame 102. Two bolts 204 are inserted into the left and right sides of each pair of clamping seats 201 on the same side, and nuts are used to secure the two clamping seats 201 on each side to the utility pole. This allows the transformer 101 to be fixedly placed between utility poles of varying spacing, with the two clamping seats 201 positioned close to the transformer. The device 101 is slid into the front and rear sides of the bottom frame 102, allowing the two clamping seats 201 to slide and fit onto the utility poles at different intervals on both sides. Then, two more clamping seats 201 are placed on the front and rear sides of the bottom frame 102, so that the two newly placed clamping seats 201 can fit against the outer side of the utility poles on both sides. Then, the two clamping seats 201 are fixed and clamped onto the utility poles by bolts 204 and nuts on each pair of clamping seats 201. The structure is simple, the operation is convenient, and the efficiency of disassembly and installation is effectively improved, making it easy for the transformer to be stably installed between utility poles at different intervals.

[0019] This section is based on Figure 1-8 The working process described is as follows: an opening slot is provided at each of the four corners of the bottom frame 102 to facilitate the sequential installation of the clamping seats 201 on the front and rear sides of the bottom frame 102, thereby clamping and fixing the utility pole and improving the stability of the transformer 101.

[0020] This section is based on Figure 1-8The working process described is as follows: the inner side of each clamping seat 201 is an arc-shaped surface, which facilitates clamping and fixing the utility pole from both sides.

[0021] This section is based on Figure 1-8 The working process described is as follows: the arc surface of each clamping seat 201 is roughened to improve the friction between each clamping seat 201 and the utility pole, thereby improving the stability during clamping.

[0022] This section is based on Figure 1-8 The working process described is as follows: To facilitate the clamping and fixing of each utility pole by each clamping seat 201, the small advertisements stuck to the upper side of the utility pole can be scraped and wiped off. Thus, a scraper plate 202 that can scrape off small advertisement paper scraps is slidably connected to the upper side of each clamping seat 201. The elongated hole in the middle of each scraper plate 202 further enhances the efficiency of scraping off small advertisements. When in use, the operator grabs the handle on the outside of any scraper plate 202 and pushes each scraper plate 202 upwards. Then, the scraper plate 202 scrapes the sides of the utility pole, causing the small advertisements to fall off, thus improving the cleanliness of the street.

[0023] Each scraper 202 has sharp surfaces on its upper and lower sides and on its upper and lower sides of the long strip hole in the middle.

[0024] This section is based on Figure 1-8 The working process described is as follows: when any scraper 202 scrapes the small advertisement on the utility pole, the sharp surfaces on the upper and lower sides of each scraper 202 and the upper and lower sides of the long hole in the middle of each scraper 202 quickly scrape off the small advertisement, thereby improving the overall functionality of the device.

[0025] Each scraper 202 is fixedly connected to an arc-shaped flushing pipe 203 on its rear side. The inner side of each flushing pipe 203 is uniformly fixed along the circumferential direction and connected to multiple upward-facing spray pipes.

[0026] This section is based on Figure 1-8 The working process described is as follows: In order to facilitate the scraping of small advertisements and wash away the paper scraps generated by the advertisements, while scraping any scraper 202, alcohol cleaning liquid is sprayed out through the arc-shaped flushing pipe 203 fixed to the upper side of each scraper 202 by bolts, using multiple nozzles arranged in the inner circumference direction, so as to improve the efficiency of scraping the paper scraps of small advertisements. Each nozzle is oriented upward to improve the flushing efficiency.

[0027] A protective cover 301 is slidably connected to the left and right sides of the bottom frame 102. A rotating rod 302 is rotatably connected to the front and rear sides of the middle of each protective cover 301. A pulley is fixedly connected to the outer side of each rotating rod 302. Each pulley on the same side is connected by two belts 303 for transmission. A fan blade frame 304 is fixedly connected to the inner side of each rotating rod 302. Multiple fan blades are evenly arranged on each fan blade frame 304 along the circumferential direction.

[0028] This section is based on Figure 1-8 The working process described is as follows: To facilitate the clamping and fixing of the transformer to the utility pole while simultaneously cooling it rapidly, during use, the output shaft of a motor is fixedly connected to the outer side of each rear rotating rod 302 via a coupling, driving two motors to rotate the rear rotating rod 302. This rotation, driven by pulleys and two belts 303, causes each rotating rod 302 to rotate. Simultaneously, the fan blade frame 304, bolted to each rotating rod 302, rotates, causing the fan blades on each frame to rotate, generating a certain wind speed to rapidly cool the sides of the transformer, which are fastened within the protective covers 301, thus improving the transformer's service life. Furthermore, a movable end of an electric push rod is pre-connected to the lower side of each protective cover 301 via a flange, and the fixed ends of the two electric push rods are fixedly connected to the left and right sides of the bottom frame 102 via flanges. Driving the two electric push rods causes the protective covers 301 to fasten to the left and right sides of the transformer, facilitating rapid and targeted cooling of both sides of the transformer.

[0029] Each of the fan blades is made of metal.

[0030] This section is based on Figure 1-8 The working process described is: making each fan blade a metal material to increase wind speed, thereby causing the transformer temperature to drop rapidly.

[0031] Each of the protective covers 301 has multiple ventilation holes on its front and rear sides.

[0032] This section is based on Figure 1-8 The working process described herein is as follows: multiple ventilation holes are processed on both the front and rear sides of each protective cover 301 to improve the air permeability of each protective cover 301 during cooling operation.
