Description

Technical Field

[0001] The utility model relates to the technical field of universal circuit breakers, in particular to a universal circuit breaker with a dustproof function. Background Art

[0002] A universal circuit breaker is a mechanical switch that can connect, carry and disconnect current under normal circuit conditions, and can also connect, carry for a certain time and disconnect current under specified abnormal circuit conditions. Universal circuit breakers are used to distribute electrical energy and protect circuits and power equipment from overload, undervoltage, short circuit, etc. In addition to controlling, universal circuit breakers can also protect. Once a power line or electrical equipment fault is detected, the main contacts of the universal circuit breaker are immediately disconnected to interrupt the circuit. There are many types of universal circuit breakers currently available on the market, but there are still some disadvantages;

[0003] For example, in actual use, a universal circuit breaker is generally exposed to the air for a long time, and a large amount of dust will be absorbed inside. After the dust is deposited, it will cause a short circuit in the universal circuit breaker. At the same time, after a protective cover is set, the door of the protective cover is often opened, which will also cause dust to accumulate inside the universal circuit breaker. Failure to handle the dust will also cause the internal components of the universal circuit breaker to become insensitive. In addition, the protective cover is generally not easy to disassemble. Once damaged, it is difficult to replace it. Therefore, we propose a universal circuit breaker with a dustproof function to solve the above problems. Utility Model Content

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] See also Figure 1-5 The utility model provides a technical solution: a universal circuit breaker with dustproof function, comprising: a circuit breaker body 1, a mounting rod 2, a fixing hole 3, a connecting pin 4, a protective cover 5, a fixing rod 6, a heat dissipation hole 7, a dustproof net 8, an electric fan 9, a door 10, a threaded rod 11, a fixing block 12, a limit rod 13, a support rod 14, an electrostatic duster 15, a first pulley 16, a connecting belt 17, a second pulley 18 and a motor 19;

[0027] like Figure 1 , Figure 2 and Figure 3 As shown in the figure, when the circuit breaker body 1 is exposed to the air for a long time, a large amount of dust will be absorbed inside. After the dust is deposited, a short circuit will occur in the circuit breaker body 1. That is, a protective cover 5 is arranged on the outside of the circuit breaker body 1. The protective cover 5 can prevent dust from entering the circuit breaker body 1, thereby avoiding the short circuit of the circuit breaker body 1. At the same time, heat dissipation holes 7 are symmetrically opened on the left and right sides of the inside of the protective cover 5. The setting of the heat dissipation holes 7 can prevent the protective cover 5 from blocking dust without affecting the heat dissipation of the circuit breaker body 1. In addition, a dustproof net 8 is installed in the heat dissipation hole 7, and the dustproof net 8 can prevent dust from entering the circuit breaker body 1 from the heat dissipation hole 7. An electric fan 9 is arranged above the inside of the protective cover 5. Turning on the electric fan 9 will accelerate the heat dissipation of the circuit breaker body 1.

[0028] like Figure 1 , Figure 4 and Figure 5As shown in the figure, connecting pins 4 are symmetrically and equidistantly arranged on the left and right sides of the rear of the protective cover 5, and the connecting pins 4 are inserted into the fixing holes 3 opened inside the mounting rod 2. After the connecting pins 4 enter the fixing holes 3, the fixing rods 6 are inserted into the mounting rods 2 from the top of the mounting rods 2 to fix the connecting pins 4 and the mounting rods 2. If the protective cover 5 is damaged and needs to be replaced, the fixing rods 6 are taken out from the inside of the mounting rods 2, so that the connecting pins 4 and the fixing holes 3 opened inside the mounting rods 2 will fall off, which makes it convenient to disassemble and replace the protective cover 5.

[0029] like Figure 3 and Figure 5 As shown in the figure, the operating workers often open the door 10 to operate and inspect the circuit breaker body 1, which will cause dust to accumulate inside the circuit breaker body 1. If the dust is not handled, the internal components of the circuit breaker body 1 will become insensitive, that is, the door 10 is installed in front of the protective cover 5, and the threaded rod 11 is rotatably installed inside the door 10. The outer side of the threaded rod 11 is threadedly connected to the fixing block 12, and the rear side of the fixing block 12 is installed with a support rod 14. The rear end of the support rod 14 is fixed with an electrostatic duster 15 by bolts. The electrostatic duster 15 fits tightly with the circuit breaker body 1, and a first pulley 16 is installed on the outer side of the upper end of the threaded rod 11. A connecting belt 17 is arranged on the outer side of the first pulley 16. A second pulley 18 is installed inside the rear of the connecting belt 17, and a motor 19 is connected to the upper end of the second pulley 18. Turn on the motor 19, the motor 19 can make the second pulley 18 rotate, and through the connection with the connecting belt 17, the first pulley 16 will also rotate, that is, the first pulley 16 will drive the threaded rod 11 at the lower middle part to rotate together. When the threaded rod 11 rotates, since the limit rod 13 is engaged with the left inner part of the fixed block 12, the limit rod 13 will limit the fixed block 12, that is, the fixed block 12 will move up and down on the outside of the threaded rod 11. When the fixed block 12 moves up and down, it can drive the electrostatic dust duster 15 to move up and down to absorb the dust on the circuit breaker body 1, so that the circuit breaker body 1 remains clean. Since the electrostatic dust duster 15 is fixedly connected to the support rod 14 by bolts, when the electrostatic dust duster 15 needs to be replaced, the bolts of the fixed support rod 14 and the electrostatic dust duster 15 can be directly unscrewed for replacement.
