[0003] Traditional protective measures for outdoor transformers generally use devices such as protective covers, insulating sleeves or waterproof sleeves on outdoor transformers. This kind of protective measure requires designing a silicone rubber sleeve according to the size of the transformer additionally, carrying out mold opening production on the silicone rubber sleeve, then sticking the silicone rubber sleeve on the transformer with glue, and sealing the joint with glue. This kind of protective measure consumes process time, materials and labor. If the silicone rubber sleeve is damaged, it is not convenient to replace. The silicone rubber sleeve has a certain thickness, and after being sleeved on the transformer, it increases the external dimension of the transformer and occupies space. Content of the Utility Model
[0004] To solve the above problems, the utility model provides a spraying auxiliary device for outdoor transformers, which is beneficial to the deployment of the protective layer spraying on the surface of outdoor transformers, makes the spraying more uniform, and has a better anti-fouling and waterproof effect.
[0005] To achieve the above purpose, the technical scheme adopted by the utility model is as follows: a spraying auxiliary device for outdoor transformers is provided, which includes a transformer fixing frame. The transformer fixing frame includes a base, a first side bracket and a rotating bracket. There are two first side brackets, which are respectively arranged on the left and right sides of the base. The rotating bracket includes a bottom frame and a second side bracket which are connected with each other. Threaded holes corresponding to the bottom mounting holes of the outdoor transformer are arranged on the bottom frame. The bottom of the outdoor transformer is placed on the bottom frame, and the outdoor transformer is fixed to the transformer fixing frame through screws that simultaneously pass through the threaded holes on the bottom frame and the bottom mounting holes of the outdoor transformer. The second side bracket and the first side bracket are rotationally connected through a bearing. A plurality of first through holes are arranged on the first side bracket, and a plurality of second through holes corresponding to the positions of the first through holes are arranged on the second side bracket. The first through holes and the second through holes are both arranged around the center of the bearing, and the first through holes and the second through holes are used for inserting pins.
[0006] Further, there are three first through holes and three second through holes. The three first through holes and the three second through holes are respectively arranged directly below the center of the bearing and on the left and right sides.
[0007] Further, the chassis is an L-shaped steel frame.
[0008] Further, the chassis includes two parallel L-shaped steel frames, and the two ends of the L-shaped steel frames are connected to the bottom of the second side bracket.
[0009] Further, a U-shaped opening is provided on the side of the second side bracket facing the L-shaped steel frame, and the two ends of the two L-shaped steel frames are respectively connected to the bottom of the second side bracket on both sides of the U-shaped opening.
[0010] Further, the base includes a cross beam and a longitudinal beam. There are two parallel cross beams, and the longitudinal beam is vertically connected to the two cross beams.
[0011] Further, there are two parallel longitudinal beams.
[0012] Further, both the cross beam and the longitudinal beam are made of L-shaped steel plates.
[0013] The technical solution of the present utility model has the following advantages:
[0014] 1. The present utility model can rotate the outdoor mutual inductor according to the needs of different spraying angles, align one of the first through holes on the first side bracket with one of the second through holes on the second side, and insert a pin for fixation after alignment. In this way, the angle between the outdoor mutual inductor and the horizontal plane can be adjusted by selecting the first through holes and the second through holes at different positions, improving the uniformity of the spraying thickness.
[0015] 2. In the present utility model, since the outdoor mutual inductor and the chassis are always relatively fixed, an external force is applied to the chassis during the process of flipping the outdoor mutual inductor to rotate the outdoor mutual inductor. The whole process does not need to touch the outdoor mutual inductor. The spray gun can continue to evenly spray the umbrella skirt, corners, and bottom to meet the process requirements, and then be moved to a ventilated place until it dries and then the outdoor mutual inductor is removed. The whole process avoids secondary pollution, improving both the appearance performance of the mutual inductor and the uniformity of the spraying thickness.
[0016] 3. The present utility model overcomes the drawbacks of traditional protection measures for outdoor mutual inductors. The influence of the thickness of the spray coating on the external dimensions of the outdoor mutual inductor during installation can be ignored, and the uniformity of the spraying thickness is improved compared to the static spraying method. During the spraying process, by rotating the outdoor mutual inductor, the uniformity of spraying the umbrella skirt, corners, and bottom is improved, further enhancing the dust and water protection effects on the entire surface of the outdoor mutual inductor.

[0027] Traditional protective measures taken on outdoor instrument transformers generally involve using devices such as protective covers, insulating bushings or waterproof sleeves on outdoor instrument transformers. This kind of protective measure requires designing a silicone rubber sleeve according to the size of the instrument transformer additionally, carrying out mold opening production on the silicone rubber sleeve, then sticking the silicone rubber sleeve on the instrument transformer with glue, and then sealing the joint with glue. This kind of protective measure consumes process time, materials and labor. If the silicone rubber sleeve is damaged, it is not convenient to replace. The silicone rubber sleeve has a certain thickness, and after being sleeved on the instrument transformer, it increases the external dimension of the instrument transformer and occupies space.
[0028] Moreover, for conventional static spraying methods, such as placing the outdoor instrument transformer on a tray and moving the spray gun up, down, left and right for spraying, it is not conducive to effective spraying of positions that need to be sprayed multiple times on the umbrella skirt, corners, bottom, etc. of the outdoor instrument transformer. These places often need to be moved during the spraying process in order to align with the spray gun nozzle, and it is easy to get dusty during the moving process, affecting the appearance effect of spraying. And the static spraying method is prone to cause uneven coating, resulting in weak anti-fouling performance in these parts.
[0029] Based on the above problems, the embodiment of the present utility model provides a spraying auxiliary device for an outdoor instrument transformer, which improves the spraying uniformity of the outdoor instrument transformer and improves the dustproof and waterproof effects of the coating.
[0030] Please refer to Figures 1 to 3As shown, an embodiment of the utility model provides a spraying auxiliary device for an outdoor transformer, including a transformer fixing frame, the transformer fixing frame includes a base 3, a first side bracket 2 and a rotating bracket, the first side bracket 2 has two, which are respectively arranged on the left and right sides of the base 3, the rotating bracket includes a base frame 8 and a second side bracket 7 connected to each other, the base frame 8 is provided with a threaded hole 9 corresponding to the bottom mounting hole of the outdoor transformer, the bottom of the outdoor transformer is placed on the base frame 8, the outdoor transformer is fixed to the transformer fixing frame by screws that simultaneously pass through the threaded hole 9 on the base frame 8 and the bottom mounting hole of the outdoor transformer, the second side bracket 7 is rotatably connected to the first side bracket 2 through a bearing 4, the first side bracket 2 is provided with a plurality of first through holes 5, the second side bracket 7 is provided with a plurality of second through holes 6 corresponding to the position of the first through holes 5, the first through holes 5 and the second through holes 6 are both arranged around the center periphery of the bearing 4, and the first through holes 5 and the second through holes 6 are used to insert pins.
[0031] When installing the outdoor transformer, place the bottom of the outdoor transformer 1 on the base frame 8, align the mounting hole of the bottom of the outdoor transformer 1 with the threaded hole 9 on the base frame 8, and screw in the screws to fix the bottom. At the same time, the first side plate bracket is rotatably connected to the second side bracket 7 through the bearing 4. According to the needs of different spraying angles, the outdoor mutual inductor is rotated, and a first through hole 5 on the first side bracket 2 is aligned with one of the second through holes 6 on the second side. After alignment, a pin is inserted to fix it. In this way, the angle between the outdoor mutual inductor and the horizontal plane is adjustable due to the selection of the first through hole 5 and the second through hole 6 at different positions, thereby improving the uniformity of the spraying thickness. In the process of flipping the outdoor mutual inductor, because the outdoor mutual inductor 1 is fixed on the base frame 8, an external force is applied to the base frame 8 to rotate the outdoor mutual inductor. The entire process does not require touching the outdoor mutual inductor. The spray gun continues to evenly spray the umbrella skirt, corners, and bottom to meet the process requirements. The outdoor mutual inductor is transported to a ventilated place until it is dry and then the outdoor mutual inductor is removed. The entire process avoids secondary pollution, which not only improves the appearance performance of the mutual inductor, but also improves the uniformity of the spraying thickness.
[0032] In some embodiments of the utility model, three of the first through holes 5 and three of the second through holes 6 are provided, and the three first through holes 5 and the three second through holes 6 are respectively arranged directly below and on the left and right sides of the center of the bearing 4, meeting the need for spraying the outdoor mutual inductor at different angles.
[0033] In some embodiments of the utility model, the base frame 8 is an L-shaped steel frame, which has a stable structure, can better bear force, and has a good supporting effect. In addition, the base frame 8 is an L-shaped steel frame, and the side extending from the L-shaped steel frame also provides a better rotation force-bearing part for rotating the outdoor mutual inductor.
[0034] In some embodiments of the present invention, the base frame 8 includes two L-shaped steel frames arranged in parallel, and both ends of the L-shaped steel frames are connected to the bottom of the second side bracket 7.
[0035] In some embodiments of the present invention, a U-shaped opening is provided on one side of the second side bracket 7 facing the L-shaped steel frame, and the two ends of the two L-shaped steel frames are respectively connected to the bottom of the second side bracket 7 on both sides of the U-shaped opening. Providing the U-shaped opening not only saves material and reduces deadweight, but also stabilizes the force and does not affect the supporting effect.
[0036] In some embodiments of the present invention, the base 3 includes a cross beam and a longitudinal beam. Two cross beams are provided and are parallel to each other. The longitudinal beam vertically connects the two cross beams. The base 3 is more stable, has uniform force, and is not easy to shake.

[0038] In some embodiments of the present invention, the cross beam and the longitudinal beam are both made of L-shaped steel plates, and the structure is firm.
[0039] The working principle of the utility model is as follows: first, install the outdoor mutual inductor 1 whose surface has not been sprayed on the auxiliary device, align the mounting hole at the bottom of the outdoor mutual inductor with the threaded hole 9 on the base frame 8, and screw in the screws to fix the bottom. At the same time, the first side panel bracket is rotatably connected with the second side bracket 7 through the bearing 4. According to the needs of different spraying angles, by applying external force to the base frame 8, after rotating the outdoor mutual inductor at a certain angle, a first through hole 5 on the first side bracket 2 is aligned with one of the second through holes 6 on the second side bracket 7, and a pin is inserted to fix it after alignment. At this angle, the spray gun sprays the surface of the outdoor mutual inductor 1. When it is necessary to spray other surfaces of the outdoor mutual inductor 1 at a better angle, remove the pin, apply external force to the base frame 8 again, rotate the outdoor mutual inductor at other angles, align the first through hole 5 on the first side bracket 2 with the second through hole 6 on the second side bracket 7, and then insert the pin to complete the surface spraying of the outdoor mutual inductor at another angle. There is no need to touch the outdoor transformer during the whole process. The spray gun continues to evenly spray the shed, corners and bottom to meet the process requirements. It is then moved to a ventilated place and removed after it is dry. The whole process avoids secondary pollution, which not only improves the appearance performance of the transformer, but also improves the uniformity of the spray thickness.
[0040] In summary, the utility model overcomes the drawbacks of traditional protection measures for outdoor instrument transformers, and improves the uniformity of spraying thickness compared with the static spraying method. During the spraying process, by rotating the outdoor instrument transformer 1, the spraying uniformity of the umbrella skirt, corners and bottom is improved, and further improves the dust and water protection effect of the entire surface of the outdoor instrument transformer 1.
