[0016] Technical effects and advantages of the present invention:

[0017] 1. The present invention adopts a bilateral anti-movement mechanism. When the circuit breaker is not closed and the current detector detects the current, the driving motor drives the linkage screw to rotate. The two articulated sleeves approach each other under the action of the thread transmission force, and the articulated shaft causes the sleeve rod to move backward. The sleeve rod drives the push shaft to move toward the side of the limit slider. The sleeve plate rotates counterclockwise on the outer wall of the positioning column, and the other sleeve plate rotates clockwise on the outer wall of the other positioning column. When the pressure value sensed by the pressure sensor is the same as the pressure value set by the controller, the driving motor is turned off by the controller, and the two sleeve plates can limit the two sides of the limit slider for anti-movement, so as to avoid the high-voltage arc caused by directly disconnecting the trolley in the closed state, thereby avoiding damage to equipment and personal injury, and greatly improving the safety of high-voltage switch cabinet.

[0018] 2. The present invention utilizes a detection embedded component and a current detector powered by a battery. The power-on probe on the current detector can be connected to the power-on terminal to energize it. When there is no current, it is known that the circuit breaker has been closed. External maintenance personnel can insert the tool into the inner wall of the end of the trolley screw and perform the normal pull-out and separation operation of the trolley. When the current detector detects the current, the drive motor is started through the controller and the electric cylinder is moved at the same time. The electric cylinder pushes the push bar to move right, and the positioning block is inserted into the positioning hole inside the limit slider. The trolley can continue to perform internal limit movement prevention, avoiding the rightward separation operation of the trolley when the circuit breaker is not closed, and avoiding the generation of high-voltage arc by directly disconnecting the trolley in the closed state. The large high-voltage switch cabinet is safer to use.

[0019] 3. The present invention adopts a wheel linkage anti-movement mechanism. The reduction motor drives the transmission screw to rotate, and the transmission screw drives the two threaded sleeves to move right under the action of the thread transmission force. The tooth plate drives the gear to rotate counterclockwise, the gear drives the limit sleeve to rotate counterclockwise, and the positioning shaft drives the proximity sensor to rotate counterclockwise. The two rollers are limited and prevented from moving by the two limit sleeves, so as to prevent the two rollers on the trolley from moving right and rolling in the closed state, thereby avoiding the generation of high-voltage arc and greatly improving the safety of high-voltage switchgear.

[0020] According to the mutual influence of the above multiple functions, first, when the current detector detects the current, the driving motor is started through the controller, and then the two sleeves can limit the two sides of the limit slider to prevent movement, and the positioning block is inserted into the positioning hole inside the limit slider, and finally the two limit sleeves respectively limit the two rollers to prevent movement. In summary, when the current is detected, multiple anti-movement operations can be implemented to avoid direct disconnection of the trolley in the closed state, avoid equipment damage and personnel injury caused by high-voltage arcs, and greatly improve the safety of high-voltage switchgear.

The vertical cross-section of the positioning shaft 39 is circular, and the limiting sleeve 40 is rotatably connected to the positioning shaft 39 .

[0041] The working principle of the indoor metal armored high-voltage switch cabinet of the present invention is as follows:

[0042] First, when the present invention is used in armor, the armored cabinet 1 is reinforced with metal armor, so that the armored cabinet 1 is more stable and firm during outdoor use, and has better resistance to external impact. Then, by closing the safety door 20, the safety door 20 and the armored cabinet 1 are closed, and after closing, the circuit breaker 45 can be opened through the controller 21, so that the circuit breaker 45 is connected to the mains, and the trolley terminal 23 on the trolley 2 is connected to the power terminal 24, and the outer wall insulation material of the power terminal 24 is firmly fixed to the armored cabinet 1, and the top of the power terminal 24 is connected and then connected externally, and the circuit breaker 45 supplies power to the trolley terminal 23 on the trolley 2, so that the trolley terminal 23 supplies power to the power terminal 24, realizing high-voltage power supply, and closing the circuit breaker 45 can cut off the high-voltage circuit.

[0043] Secondly, when the present invention is embedded for detection, the current detector 26 is powered by the battery 27, and the power probe 25 on the current detector 26 can be connected to the power terminal 24 to be energized, so that the current is detected by the current detector 26. When there is no current, it is known that the circuit breaker 45 has been closed. In this way, the external maintenance personnel can insert the tool into the inner wall of the end of the trolley screw 43, and by rotating the trolley screw 43, the trolley screw 43 rotates stably inside the bearing sleeve 44. At the same time, the trolley screw 43 drives the trolley sleeve block 42 to move right under the action of the thread transmission force, and at the same time, the trolley sleeve block 42 slides to the right at the upper limit of the slide rail 31. At the same time, the trolley sleeve block 42 drives the sleeve plate 28 to move right, the sleeve plate 28 causes the two limit shafts 29 to move right, the limit shafts 29 roll right along the outer wall of the slide rail 31, and the trolley 2 drives the circuit breaker 45 to move right, and the trolley 2 drives the trolley terminal 23 to move right, the trolley terminal 23 and the power terminal 24 are separated, and the trolley 2 can be moved out from the armored cabinet 1.

[0044] When the current detector 26 detects the current, the driving motor 7 is started through the controller 21 to realize the driving operation of the driving motor 7 .

[0045] Then, when the present invention performs bilateral anti-movement, the linkage screw 6 is driven to rotate by the driving motor 7, and the linkage screw 6 rotates inside the support frame 5. At the same time, the linkage screw 6 drives the two articulated sleeves 8 to approach each other under the action of the thread transmission force, and the articulated sleeve 8 drives the articulated shaft 9 to move backward, while the other articulated sleeve 8 moves forward, and the articulated shaft 9 makes the sleeve rod 10 move backward, and the sleeve rod 10 drives the push shaft 11 to move closer to the side of the limit slider 3, and the push shaft 11 drives the articulated block 12 to move closer to the side of the limit slider 3, and the articulated block 12 drives the sleeve plate 13 to move closer to the side of the limit slider 3. At the same time, the sleeve plate 13 drives the pressure sensor 16 to move closer to the side of the limit slider 3, and the sleeve plate 13 rotates counterclockwise on the outer wall of the positioning column 14, and the other sleeve plate 13 rotates clockwise on the outer wall of the other positioning column 14. In this way, the two sleeve plates 13 are respectively pressed on the two side surfaces of the limit slider 3, and the pressure sensor 16 is pressed on the side surface of the limit slider 3. When the pressure value sensed by the pressure sensor 16 is the same as the pressure value set by the controller 21, the drive motor 7 is turned off by the controller 21.

[0046] The two sleeve plates 13 can limit and prevent the two sides of the limit slider 3 from moving. At the same time, the electric cylinder 17 is started. The electric cylinder 17 pushes the push bar 18 to move right. The push bar 18 makes the positioning block 19 move right, and the positioning block 19 can move right synchronously. The positioning block 19 is inserted into the positioning hole 15 inside the limit slider 3. By positioning the positioning block 19 and the positioning hole 15, the handcart 2 can continue to be internally limited and prevented from moving, thereby preventing the handcart 2 from moving due to accidental operation.

[0047] Finally, when the present invention performs wheel linkage anti-motion, the reduction motor 34 is started through the controller 21, and the reduction motor 34 drives the transmission screw 33 to rotate, and the transmission screw 33 drives the two threaded sleeves 35 to move right under the action of the thread transmission force, and the two threaded sleeves 35 slide right on the outer wall of the slide bar 36.

[0048] At the same time, the threaded sleeve 35 drives the tooth plate 37 to move right, the tooth plate 37 drives the gear 38 to rotate counterclockwise, the gear 38 rotates counterclockwise on the outer wall of the positioning shaft 39, the gear 38 drives the limit sleeve 40 to rotate counterclockwise, the limit sleeve 40 rotates counterclockwise along the outer wall of the positioning shaft 39, and the positioning shaft 39 drives the proximity sensor 41 to rotate counterclockwise. When the limit sleeve 40 rotates and contacts the outer wall of the roller 30, the two limit sleeves 40 are used to limit the two rollers 30 to prevent them from moving right, and then the limit sleeve 40 drives the proximity sensor 41 to rotate counterclockwise, and the proximity sensor 41 approaches the roller 30. The roller 30 is sensed by the proximity sensor 41. When the roller 30 is sensed, the reduction motor 34 is turned off by the controller 21, so that the two rollers 30 are linked to prevent movement.
