Description

Technical Field

[0001] The utility model relates to the technical field of voltage transformers, in particular to a transformer with a protection function. Background Art

[0002] In industrial production sites, instrument transformers need to monitor under harsh conditions such as high temperature, high pressure, corrosive gases or liquids. Instrument transformers with protection functions can ensure that they can still work reliably under these conditions and monitor key parameters such as temperature, pressure, liquid level, etc. In vehicles such as cars, trains, and airplanes, instrument transformers need to be able to withstand the influence of factors such as vibration, humidity, and temperature changes. These instrument transformers are used to monitor engine temperature, oil pressure, vehicle speed, brake system status, etc. to ensure the safety and reliability of vehicles.

The transformer with a protective function starts the motor to rotate the worm, which drives the worm wheel to rotate. When the worm wheel rotates, the threaded rod is rotated synchronously. At this time, the rotating threaded rod will drive the sliding tube to slide upward on its outer wall, and the sliding tube sliding upward will rise with the protective shell, and will no longer cover the transformer body, so that the transformer body is directly separated from the protective shell and exposed. At this time, it is convenient for the staff to inspect and maintain it, and as long as the protective shell is lowered or raised, the rolling brush can brush the surface of the transformer body once.

[0004] The above patent embodiment records that "by starting the motor, the worm rotates, driving the worm wheel to rotate, and when the worm wheel rotates, the threaded rod rotates synchronously. At this time, the rotating threaded rod will drive the sliding tube to slide upward on its outer wall, and the sliding tube that slides upward will rise upward with the protective shell, and will no longer cover the transformer body." The above embodiment records that by starting the motor, the output end of the motor drives the worm to rotate, so that when the worm rotates, it will drive the threaded rod to rotate through the worm wheel, and then the threaded rod will drive the protective shell to move through the sliding tube when it rotates, and when the protective shell is transported, it will drive the rolling brush to brush the surface of the transformer. However, it does not take into account that when the staff needs to inspect the transformer, the transformer cannot be quickly disassembled. Therefore, in view of the above-mentioned deficiencies, a new type of transformer with protective function is proposed. Utility Model Content

[0023] Reference Figure 1 - Figure 2The utility model provides an embodiment: a transformer with a protective function, including a mounting plate 1, which is the basic component of the transformer, used to support the entire structure and provide an installation position. It is usually made of a solid material to ensure that the transformer is firmly fixed during use. The front and rear sides of the mounting plate 1 are provided with cavities 2, which are used to accommodate other components and provide space to ensure their normal operation. The insides of the two cavities 2 are fixedly connected with sliding shafts 3, which are fixedly connected inside the cavities 2. Their function is to support and guide the movement of other moving parts to ensure the normal operation of the transformer.

[0024] The outside of the two sliding shafts 3 are both sleeved with a spring 4. The spring installed on the outside of the sliding shaft 3 may be used to provide a reverse force or a rebound force to maintain a close connection between the components of the mutual inductor or restore them to their original positions. The outside of the two sliding shafts 3 are both slidably connected with a pulling plate 5, so that the sliding shaft 3 can make the pulling plate 5 move more stably. One end of the spring 4 is fixedly connected to the inner wall of the adjacent side of the two cavities 2, and the other end of the spring 4 is fixedly connected to the adjacent side of the two pulling plates 5, so that the pulling plate 5 will compress the spring 4 when it moves. A shell 6 is provided on the top of the mounting plate 1, and the front and rear sides of the bottom of the shell 6 are fixedly connected with an insertion plate 7. The far sides of the tops of the two pulling plates 5 respectively penetrate the interior of the two cavities 2 and extend outward.

[0025] The bottoms of the two insertion plates 7 are respectively slidably connected to the insides of the two cavities 2. The bottoms of the two insertion plates 7 are provided with snap-fitting components, which include two snap-fitting grooves 8. The two snap-fitting grooves 8 are respectively provided at the bottoms of the two insertion plates 7. The adjacent sides of the two pulling plates 5 are respectively snap-fitted with the insides of the two snap-fitting grooves 8, so that the pulling plates 5 can fix the insertion plates 7 by snapping with the snap-fitting grooves 8. A transformer body 14 is provided inside the outer shell 6, so that the outer shell 6 can provide preliminary protection for the transformer body 14.

[0026] like Figure 1 and Figure 3 As shown: a partition 15 is fixedly connected to the inner top side of the shell 6, so that the partition 15 can divide the inner space of the shell 6, a fixing rod 16 is fixedly connected to the inner top side of the shell 6, and the shell 6 can provide support for the fixing rod 16, springs 29 are sleeved on the left and right sides of the outside of the fixing rod 16, and sliding blocks 10 are slidably connected on the left and right sides of the outside of the fixing rod 16, and then the fixing rod 16 can make the movement of the sliding block 10 more stable, one end of the spring 29 is fixedly connected to the far side of the two sliding blocks 10, and the other end of the spring 29 is fixedly connected to the inner wall of the shell 6, and then the sliding block 10 will compress the spring 29 when it moves.

[0027] The tops of the two sliding blocks 10 are both rotatably connected to a connecting plate 11, so that when the sliding block 10 moves, the connecting plate 11 will be driven to move; the tops of the two connecting plates 11 are both rotatably connected to a fixed plate 12, and then when the connecting plate 11 moves, the fixed plate 12 will be driven to move; the tops of the two fixed plates 12 are fixedly connected to a force-bearing plate 13, and then when the fixed plate 12 moves, the force-bearing plate 13 will be driven to move; the outside of the force-bearing plate 13 contacts the inner wall of the outer shell 6, and the bottom of the sliding block 10 contacts the top of the insertion plate 7.

[0028] Compared with some existing technologies, the above content can make the device slide outside the sliding shaft 3 by pulling the pulling plate 5 during use, and then the pulling plate 5 will compress the spring 1 4 when sliding outside the sliding shaft 3, and then the pulling plate 5 can be disengaged from the engaging groove 8, so that the mutual inductor can be quickly installed and disassembled, which is convenient for the staff to inspect and repair it, and the impact force can be transmitted to the fixed plate 12 through the force plate 13, and then transmitted to the sliding block 10 through the fixed plate 12, so that the sliding block 10 can slide outside the fixed rod 16, and then the sliding block 10 will compress the spring 2 9 when moving, and then absorb the impact force generated by the impact when compressing the spring 2 9, so as to achieve protection of the device.

[0029] Working principle: When the staff needs to inspect the device, they can pull the pulling plate 5 to make the bottom of the pulling plate 5 slide outside the sliding shaft 3, so that the pulling plate 5 will compress the spring 4 when moving, and then the pulling plate 5 will be disengaged from the inside of the engaging groove 8, and then the insertion plate 7 can be taken out from the inside of the cavity 2, so that the outer shell 6 can be removed from the top of the mounting plate 1, making it convenient for the staff to inspect the transformer body 14.

[0030] When the top of the device is hit, the force-bearing plate 13 will be pressed first, so that the force-bearing plate 13 will drive the fixed plate 12 to move, and then the fixed plate 12 will drive the connecting plate 11 to move when it moves, and then the connecting plate 11 will drive the sliding block 10 to move when it moves, so that the sliding block 10 will slide outside the fixed rod 16, and then the sliding block 10 will compress the spring 2 9 when it slides outside the fixed rod 16, and then the spring 2 9 will absorb the impact force generated by the impact when it is compressed, thereby improving the protection ability of the device.

[0031] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention.
