Description

Technical Field

[0001] This invention relates to the field of 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 energy-saving transformers and improve energy resource utilization efficiency, existing technologies, such as the power transformer described in application number 202210501035.8, have the advantage of quickly adjusting the core and the number of windings, but are not suitable for the freely movable use of power transformers. Summary of the Invention

[0003] The purpose of this invention is to provide a power transformer that allows for easy and portable use.

[0004] The objective of this invention is achieved through the following technical solution: a power transformer, comprising a transformer and a base frame fixedly connected to the bottom of the transformer, wherein a rotating wheel is rotatably connected to each of the four corners of the bottom of the base frame.

[0005] Each of the aforementioned wheels is made of rubber.

[0006] A limiting wheel is slidably connected to each of the four corners of the base frame. The two limiting wheels located on the rear side are rotatably connected to the right side of a cross frame, and the two limiting wheels located on the front side are rotatably connected to the right side of another cross frame. A clamping frame I is fixedly connected to the left side of each of the two cross frames, and a clamping frame II is slidably connected to each clamping frame I.

[0007] The two clamping frames I are arranged in a mirror image.

[0018] This section is based on Figure 1 , 2 The working process described in 7 and 8 is as follows: In order to facilitate the use of the power transformer by moving it at will, a base frame 102 is fixedly connected to the bottom of the transformer 101 by welding. A rotating wheel 103 is rotatably connected to each of the four corners of the bottom of the base frame 102. When the transformer 101 is used to provide a temporary workplace for the power transformer, the transformer 101 is moved by manually pushing it and using the rotating wheel 103 located on the lower side of the transformer 101, thereby facilitating the use of the power transformer by moving it at will.

[0019] This section is based on Figure 1 , 2 The working process described in 7 and 8 is: each of the aforementioned rotating wheels 103 is made of rubber, which makes it easier to move the transformer.

[0020] This section is based on Figure 1-4The working process described in sections 7 and 8 is as follows: When temporarily using a transformer on a construction site, to facilitate fixing the transformer between two utility poles and thus improve its stability, two crossbeams 202 are slidably connected to the front and rear sides of the base frame 102 via four limiting wheels 203. This allows the two crossbeams 202 to move on the front and rear sides of the base frame 102 using the four limiting wheels 203, thereby fixing the transformer between the two utility poles and facilitating wire connection. A clamping frame is bolted to the left side of each crossbeam 202. Each clamping frame I204 has two clamping frames II205, which are similar in shape to the two clamping frames I204, slidably connected to each adjacent side. When clamping two utility poles, the two utility poles are positioned between each pair of clamping frames I204 and clamping frames II205. The two utility poles are clamped and fixed by the mutual movement between each pair of clamping frames I204 and clamping frames II205. This facilitates fixing the transformer between the two utility poles, thereby improving the stability of the transformer and helping to temporarily connect the wires to the transformer.

[0021] This section is based on Figure 1-4 The working process described in 7 and 8 is as follows: the two clamping frames I 204 are mirrored and the two clamping frames II 205 are mirrored and synchronized, so that clamping and fixing work is performed between the two utility poles by each pair of clamping frames I 204 and clamping frames II 205.

[0022] This section is based on Figure 1-4 The working process described in 7 and 8 is as follows: When each pair of clamping frames I 204 and clamping frame II 205 clamps and fixes the poles between the two utility poles, a fixed end of an electric push rod 206 is fixedly connected to the outside of each clamping frame I 204 via a flange. The movable ends of the two electric push rods 206 are fixedly connected to the outside of the two clamping frames II 205 via flanges, thereby driving the two electric push rods 206 to move the two clamping frames II 205 toward the two clamping frames I 204, thus clamping and fixing the utility poles and preventing the transformer from shaking violently in strong winds, which would affect the operation of the transformer.

[0023] The right side of the base frame 102 is rotatably connected to a bidirectional lead screw 201, and the right ends of the two cross frames 202 are respectively driven to the front and rear sides of the bidirectional lead screw 201.

[0024] This section is based on Figure 1-4The working process described in 7 and 8 is as follows: When adjusting the lateral movement of the two crossbars 202 to correspond to different spacing of utility poles, the front side of the bidirectional lead screw 201 is fixedly connected to the output shaft of the first motor through a coupling. The first motor is fixedly connected to the front side of the base frame 102 by bolts. Driving the first motor causes the bidirectional lead screws 201 with different screw directions on the front and rear sides to rotate, further adjusting the lateral movement of the two crossbars 202 to perform clamping and fixing work for utility poles with different spacing.

[0025] A support rod 301 is fixedly connected to the upper and lower sides of the two clamping frames I 204 and the upper and lower sides of the two clamping frames II 205 respectively, and a cam gear 302 is rotatably connected to each support rod 301.

[0026] This section is based on Figure 1-5 The working process described in sections 7 and 8 is as follows: To improve the stability of clamping the two utility poles, a support rod 301 is fixedly connected to the upper and lower sides of the two clamping frames I 204 and the upper and lower sides of the two clamping frames II 205 by bolts. Each support rod 301 is rotatably connected to a cam gear 302. When each pair of clamping frames I 204 and clamping frames II 205 clamps the utility pole, the cam gear 302 on each support rod 301 increases the friction between the pole and the utility pole, thereby further improving the stability of the transformer when clamping the utility pole.

[0027] Each of the convex gears 302 has a plurality of sharp teeth evenly provided along the circumferential direction.

[0028] This section is based on Figure 1-5 The working process described in 7 and 8 is as follows: multiple sharp teeth are evenly provided on each cam 302 along the circumferential direction, so that each cam 302 can increase the friction between itself and the utility pole through its multiple sharp teeth in the circumferential direction.

[0029] Each of the clamping frames II 205 is rotatably connected to a crossbar 401 in the middle, and each crossbar 401 is fixedly connected to a drive wheel 402 in the middle.

[0030] This section is based on Figure 1-8The working process described is as follows: To facilitate the lifting of the transformer fixed between two utility poles and prevent other workers from contacting it, during use, the left side of each crossbar 401 is fixedly connected to the output shaft of the second motor via a coupling. Each second motor is fixedly connected to the left side of two clamping frames II 205 by bolts. When each pair of clamping frames I 204 and clamping frames II 205 clamp the utility pole, each second motor is driven, causing the power wheel 402 on each crossbar 401 to rotate. Through the friction of each power wheel 402 against one side of the utility pole, and with the cooperation of the cam gears 302 on both sides, the entire transformer is lifted, further facilitating the lifting of the transformer fixed between the two utility poles and preventing other workers from contacting it. The structure is simple and easy to use.

[0031] Each of the aforementioned power wheels 402 is provided with multiple triangular teeth evenly distributed along the circumferential direction.

[0032] This section is based on Figure 1-8 The working process described is as follows: When the transformer rises, it is driven by each power wheel 402 as a power component. The friction between the triangular teeth on each power wheel 402 and the utility pole causes it to gradually rise. The triangular teeth can increase the friction between the transformer and the utility pole, thereby improving the stability during the ascent.
