Detailed implementation manners

[0018] To make the technical means, creative features, achieved purposes and effects of the present utility model easy to understand, the present utility model will be further described below in conjunction with specific implementation manners.

[0019] As Figures 1 - 4 shown, the pole-mounted circuit breaker with deep integration includes a circuit breaker base 1. An insulating column 2 is provided on the circuit breaker base 1. An upper terminal 3 is provided at the top of the insulating column 2. A lower terminal 4 is provided on the insulating column 2. A moving structure 5 is provided at the end of the circuit breaker base 1. A bottom plate 8 is fixedly installed at the end of the circuit breaker base 1. Mounting holes 9 are symmetrically formed on the bottom plate 8. An on-off switch 6 is provided on the circuit breaker base 1. An indicating needle 7 is provided at a position close to the on-off switch 6 on the circuit breaker base 1.

[0020] When transporting the circuit breaker, the circuit breaker can be moved through the moving structure 5, which can save physical strength and time. After the circuit breaker is moved to a suitable position, the moving structure 5 will be retracted, and the circuit breaker will be lifted to a high place. It is installed and fixed through the mounting holes 9 on the bottom plate 8 in cooperation with screws, so that the circuit breaker can be used on the pole. The cable is connected to the upper terminal 3 and the lower terminal 4 on the insulating column 2, and then the circuit breaker starts to be used. During the use process, the on-off switch 6 can be used to connect and disconnect the circuit breaker, and the current state of the circuit breaker can be understood according to the indication of the indicating needle 7.

[0021] Through the above implementation solutions, the moving structure 5 includes a fixed seat 501, a movable support rod 502 and wheels 504. The fixed seat 501 is fixed at the end of the circuit breaker base 1. The movable support rod 502 is connected to the wheels 504, and the movable support rod 502 is installed on the fixed seat 501. The moving structure 5 further includes a mounting plate 503, a fixed column 505, a limiting component 506 and a driving component 507. The mounting plate 503 is fixed at the lower end of the movable support rod 502. The wheels 504 are fixed to the mounting plate 503 by screws. The fixed column 505 is fixed on the fixed seat 501, and the lower end of the fixed column 505 is connected to the bottom plate 8. The limiting component 506 is fixed at the upper end of the movable support rod 502. The driving component 507 is arranged on the limiting component 506, and the lower end of the driving component 507 is connected to the fixed column 505. The limiting component 506 includes a limiting connecting plate 5061, a U-shaped hole 5062, a connecting screw 5063 and a hand-held rod 5064. The U-shaped hole 5062 is opened on the limiting connecting plate 5061, and the limiting connecting plate 5061 is fixed to the upper end of the movable support rod 502 by the connecting screw 5063. The hand-held rod 5064 is fixed to the limiting connecting plate 5061. The driving component 507 includes a lead screw 5071, a cylinder 5072, a first baffle 5073, a second baffle 5074 and a knob 5075. The lead screw 5071 is fixedly connected to the cylinder 5072, and the lead screw 5071 is threadedly connected in the fixed column 505. The first baffle 5073 and the second baffle 5074 are fixed on the cylinder 5072, and the cylinder 5072 is located in the U-shaped hole 5062. The first baffle 5073 and the second baffle 5074 contact the limiting connecting plate 5061. The knob 5075 is fixed to the second baffle 5074. Through the provided moving structure 5, the entire circuit breaker can be quickly moved and transported by using the wheels 504, saving transportation time and physical strength. The movable support rod 502 that can be lifted is used in cooperation with the limiting component 506, the driving component 507 and the fixed column 505. The driving component 507 can drive the limiting component 506 and the movable support rod 502 to lift, and then drive the wheels 504 to extend and retract, enabling the extension and retraction of the entire moving structure 5 to be carried out quickly, with high operability. At the same time, during the process of moving the circuit breaker by using the wheels 504, due to the self-locking effect of the lead screw 5071 and the fixed column 505, the stability during movement can be ensured, guaranteeing the use effect. The limiting component 506 is detachably arranged, and can be quickly disassembled for disassembly and replacement of structures such as the driving component 507. The structure is simple and the operation is convenient and fast.

[0022] When transporting the circuit breaker, the movable support rod 502 and the wheels 504 on the mounting plate 503 are at a lower position relative to the circuit breaker base 1. The wheels 504 contact the ground to provide a supporting effect. The staff pushes the circuit breaker, and under the action of the wheels 504, the circuit breaker moves quickly. After transporting the circuit breaker to the destination, the screw rod 5071 is rotated by turning the knob 5075 in the driving component 507. The screw rod 5071 rotates and rises on the fixed column 505. Due to the limiting effect of the first baffle 5073 and the second baffle 5074 on the cylinder 5072, the limit connecting plate 5061 rises together, thus driving the movable support rod 502 and the wheels 504 to rise until the bottom plate 8 contacts the ground. At this time, the relevant structures in the moving structure 5 rise and are stored. The entire circuit breaker is lifted by the lifting rod 5064 on the limit connecting plate 5061, and the circuit breaker is carried to the bracket on the column, and then the circuit breaker can be installed. When disassembling the circuit breaker for maintenance, after the circuit breaker is carried to the ground, the screw rod 5071 is rotated again by using the knob 5075. The screw rod 5071 rotates and descends on the fixed column 505, thus driving the limit connecting plate 5061, the movable support rod 502 and the wheels 504 to descend until the wheels 504 lift the circuit breaker, and then the circuit breaker is quickly moved by using the wheels 504. After moving to the destination, the circuit breaker can be maintained. When needed, the connecting screw 5063 can be unscrewed, and the limit connecting plate 5061 can be translated so that the cylinder 5072 is removed from the U-shaped hole 5062, and then the structures such as the driving component 507 and the movable support rod 502 can be disassembled and replaced. The structure is simple and the use effect is excellent.
