[0019] Preferably, the maximum tilt angle of the trolley-type circuit breaker does not exceed 15°.

[0020] The present invention has the following beneficial effects:

[0021] 1. The present invention provides a mounting base at the bottom of the trolley-type circuit breaker, so that the trolley-type circuit breaker is mounted on the mounting base, which is convenient for disassembly and assembly. At the same time, a sliding assembly is provided at the bottom of the mounting base, and the front and rear ends of the diamond structure surrounded by four movable arms are connected by a screw rod, and the front end of the diamond structure is fixed by a fixed block. At this time, when the screw rod is rotated, the rear end of the diamond structure will continuously move toward the front end, thereby driving the diamond structure to change, and the left and right ends begin to move in opposite directions and move toward the front end at the same time. Therefore, the left and right ends of the diamond structure are connected to the mounting base, so that when the screw rod rotates, the mounting base can be driven to move at the same time. In the present invention, the sliding blocks connected to the left and right ends of the diamond structure are initially set at an end distance from the top block inside the slideway at the bottom of the mounting base, so that it is convenient to slide the left and right sides of the diamond structure at the beginning. The moving block moves in the opposite direction, driving the mounting base to move toward the outside of the trolley room. The busbar side contacts can break the circuit with the busbar contacts horizontally and smoothly until the busbar side contacts are broken and the sliding block contacts the top block. The top block drives the telescopic rod to continuously contract toward the inside of the cylinder, and the compressed gas inside the cylinder continuously moves toward the inside of the sealing tube channel, causing the compressed gas inside the sealing channel to move toward the outlet at the other end, thereby driving the movable block to move toward the outlet, and finally continuously driving the rear of the mounting base to continuously rise until the trolley-type circuit breaker moves to the door of the trolley room, making it convenient to subsequently transport the trolley room circuit breaker out of the trolley room. Since the circuit breaker is large and heavy, it can be better transported out of the relatively narrow trolley room by tilting, reducing the risk of operation inside the switch cabinet and improving the safety and efficiency of the operation process.

[0022] 2. The present invention sets a partition assembly. By disconnecting one end of the sliding assembly for transporting the circuit breaker out of the trolley chamber, when the circuit breaker is short-circuited, the movable mounting block continuously moves toward the door of the trolley chamber. At this time, the left push rod and the right push rod are driven downward by the pulling of the extension rod, driving the outgoing contact partition and the busbar contact partition to isolate one end of the busbar contact and one end of the outgoing contact. This structure can isolate the trolley chamber from the other two chambers as soon as the circuit breaker is disconnected, thereby ensuring safety during the process.

[0023] 3. The present invention sets a monitoring component. First, the monitoring module monitors the gas pressure inside the sealed channel and transmits the pressure data to the recording module. The recording module calculates the gas pressure that should be in the sealed channel based on the weight of the input trolley-type circuit breaker and the optimal angle calculated by the measuring module. Finally, the regulating module injects compressed air into the sealed channel to reach the required pressure. In this way, the movable block can be squeezed out a specific distance when the cylinder contracts, so that the mounting base is tilted to the optimal angle, which is convenient for the subsequent transportation of the circuit breaker.

[0024] 4. The present invention uses the screw of the sliding assembly to drive the diamond structure formed by the four movable arms to change. By rotating the screw, the circuit breaker can be quickly disconnected and moved to the door of the trolley room. After the circuit breaker is disconnected, the height of the rear end of the circuit breaker is continuously increased, so that the busbar side contacts and the outgoing line side contacts are no longer on the same horizontal line as the busbar contacts and the outgoing line contacts, reducing the risk of contact between the circuit breaker and the contacts, and improving the safety of the circuit breaker during disconnection and transportation.

[0045] Among them, a sealed channel is opened inside the mounting base 24, one end of the sealed channel is connected to the cylinder 23, and a movable block 25 is movably arranged inside the other end of the sealed channel, and elastic members 26 are fixedly connected on both sides of the movable block 25, and a rear pulley 27 is fixedly connected to the bottom of the movable block 25; the other end of the bottom of the mounting base 24 is fixedly connected to the front pulley 28, and the front pulley 28 and the rear pulley 27 are both slidably arranged inside the slide rail 29, and the slide rail 29 is fixedly connected to the bottom end of the inner wall of the trolley chamber 7.

[0050] The recording module adjusts the gas pressure inside the sealed channel to achieve the uniform angle between the opponent vehicle-type circuit breaker 9 and the horizontal plane.

One end of the telescopic arm 31 is fixed to the middle position of the extension rod 32. The sleeve 30 is used for the telescopic arm 31 to slide inside it. Since the movable mounting block 43 will retract into the bottom of the mounting base 24, the sleeve 30 and the telescopic arm 31 are set to facilitate the normal operation of the partition assembly.

[0055] The maximum tilt angle of the trolley-type circuit breaker 9 does not exceed 15°.

[0056] The working principle of the present invention is as follows: before the trolley-type circuit breaker 9 is installed on the mounting base 24 and pushed into the trolley chamber 7 for use, the weight of the trolley-type circuit breaker 9 is input into the measuring module of the monitoring system, and the gas pressure required inside the sealed channel is calculated according to the preset optimal angle in the measuring module and the weight of the trolley-type circuit breaker 9. After the gas pressure inside the sealed channel is changed by the adjustment module, the trolley-type circuit breaker 9 is pushed into the trolley chamber 7 through the sliding assembly and connected to the busbar contact 4 and the outgoing contact 6; when the trolley-type circuit breaker 9 needs to be disconnected, the rotating handle outside the cabinet 1 is inserted into the trolley chamber 7 through the circular hole of the cabinet door 8 and connected to the mounting shaft 12, and the rotating handle is turned to drive the screw rod 14 to rotate, and the diamond structure composed of the four transmission arms 16 begins to change, and the sliding blocks 18 fixed on the left and right sides slide in opposite directions inside the slide 19, and the movable mounting block at the rear 43 slides in the direction of the fixed block 13. During the sliding process, the sliding block 18 is blocked by a wall of the slideway 19. At the same time, the fixed block 13 fixes the front end of the diamond structure, thereby driving the trolley-type circuit breaker 9 on the mounting base 24 to disconnect the busbar contact 4 and the outgoing contact 6. The sliding block 18 slides a distance inside the slideway 19 until the busbar contact 4 and the busbar side contact 10 are disconnected. At this time, the sliding blocks 18 on the left and right sides respectively contact the top blocks 20 on both sides and squeeze the top blocks 20, driving the telescopic rod 21 to slide into the cylinder 23. The compressed gas inside the cylinder 23 moves into the sealed channel, thereby continuously squeezing the movable block 25 at the other end of the sealed channel outward, causing the rear section of the mounting base 24 to be continuously raised until the trolley-type circuit breaker 9 moves to the door position of the trolley room 7. At this point, the tilted trolley-type circuit breaker 9 can be conveniently transported out of the trolley room 7 by means of transportation tools.

Those skilled in the art should understand that the present invention is not limited to the above embodiments.
