[0015] 1. The safety protection type distribution cabinet has a driving rail arranged on the inner wall of the cabinet and a No. 1 lifting seat arranged on the outer wall of the driving rail. When the No. 1 lifting seat moves up and down along the outer wall of the driving rail, the No. 2 lifting seat can also move up and down under the pull of gravity and the traction of the traction rope, so that the interior of the cabinet can be fully scanned under the alternating operation of the two lifting seats.

The support plate 505 can rotate under the action of the driving screw 503, the slider 504 and the connecting rod 506, so that the outer wall of the support plate 505 can be parallel to the top of the circuit breaker box 5, thereby blocking the No. 1 lifting seat 404 and preventing the No. 1 lifting seat 404 from entering the inner cavity of the circuit breaker box 5.

[0041] In the above structure, by means of a fixing plate 9 arranged on the inner wall of the cabinet body 1 and a locking rod 901 arranged in the inner cavity of the fixing plate 9, the locking rod 901 can enter the inner cavity of the locking hole 11 under the action of a driving spring 903, thereby locking the outer wall of the cabinet door 2, tightly connecting the outer wall of the cabinet door 2 with the outer wall of the cabinet body 1, and monitoring the closing state of the cabinet door 2. If the cabinet door 2 is not completely closed after being opened, the closing state of the cabinet door 2 can be monitored under the action of the locking rod 901, the locking hole 11 and the trigger switch 905.

[0042] In a preferred embodiment: the power output shaft of the lifting motor 407 is connected to the outer wall of the driving shaft 405, the outer wall of the lifting gear 406 is meshed with the outer wall of the lifting tooth groove 403, and the outer wall shape of the No. 1 lifting seat 404 matches the outer wall shape of the driving rail 4.

[0044] In a preferred embodiment: the height of the No. 1 swing rod 4011 is greater than the height of the thermal imaging probe 4013, and a swing gear 4012 is installed on the outer walls of the No. 1 swing rod 4011 and the thermal imaging probe 4013, the outer wall of the swing gear 4012 is meshed with the outer wall of the rotating gear 4010, and the two ends of the outer wall of the traction rope 4017 are respectively connected to the outer walls of the No. 1 lifting seat 404 and the No. 2 lifting seat 4016.

[0045] In the above structure, by means of a rotating motor 409 arranged on the outer wall of the lifting plate 408 and a rotating gear 4010 arranged on the outer wall of the rotating motor 409, the swing gear 4012 can be driven to rotate under the drive of the rotating gear 4010, so that the No. 1 swing arm 4011 and the No. 2 swing arm 4014 can achieve cross movement, so that the temperature of the electronic components in the inner cavity of the cabinet 1 can be scanned and monitored more evenly during the cross movement of the No. 1 swing arm 4011 and the No. 2 swing arm 4014.

[0046] In a preferred embodiment: the inner wall of the slider 504 is provided with an internal thread, the outer wall of the driving screw 503 is meshed with the inner wall of the slider 504, the end of the outer wall of the connecting rod 506 away from the slider 504 is rotatably connected to the outer wall of the support plate 505, and a circuit breaker controller is installed in the inner cavity of the circuit breaker box 5, and the circuit breaker controller is electrically connected to the trigger switch 905 and the circuit breaker motor 502 respectively.

[0047] In the above structure, by means of the circuit breaker motor 502 arranged in the inner cavity of the circuit breaker box 5 and the driving screw 503 arranged on the outer wall of the circuit breaker motor 502, when the circuit breaker motor 502 is started, the slider 504 can move up and down along the outer wall of the driving screw 503 under the action of the circuit breaker motor 502, so that the angle of the support plate 505 is changed in the process of the up and down movement of the slider 504, so that the support plate 505 changes from a state parallel to the top of the circuit breaker box 5 to a vertical state, so that the No. 1 lifting seat 404 can be restricted from entering the inner cavity of the circuit breaker box 5.

[0048] In a preferred embodiment, the outer wall of the locking gear 907 is connected to the power output shaft of the locking motor 908 , and the two ends of the outer wall of the driving spring 903 are in contact with the outer wall of the fixing plate 9 and the outer wall of the limiting ring 902 respectively.

[0049] In the above structure, by means of the circuit breaker controller arranged in the inner cavity of the circuit breaker box 5, when the cabinet door 2 is closed, if the cabinet door 2 is not completely closed, the length of the arc-shaped locking plate 7 on the outer wall of the cabinet door 2 passing through the outer wall of the cabinet body 1 is limited, and the outer wall of the locking rod 901 does not enter the inner cavity of the locking hole 11. Since the depth of the movable hole 8 is less than the depth of the locking hole 11, the locking rod 901 is limited in the distance it descends, and the trigger switch 905 on the outer wall of the locking rod 901 is not triggered. At this time, the circuit breaker controller will promptly detect the fault. It is detected that the trigger switch 905 is not triggered, so the circuit breaker motor 502 is started. Under the action of the circuit breaker motor 502, the outer wall of the slider 504 is driven to move downward along the outer wall of the driving screw 503, so that the outer wall of the support plate 505 is parallel to the inner wall of the circuit breaker box 5. At this time, the No. 1 lifting seat 404 can enter the inner cavity of the circuit breaker box 5 and trigger the circuit breaker switch 501 to cut off the power to the entire cabinet 1, ensuring that when the cabinet door 2 is not fully closed, the inner cavity of the cabinet 1 is not energized, thereby better ensuring the safety of personnel and equipment.

[0050] In a preferred embodiment: the control panel 3 is electrically connected to the thermal imaging probe 4013 and the rotating motor 409 and the lifting motor 407; the inner wall shape of the No. 2 lifting seat 4016 matches the outer wall shape of the auxiliary rail 4015; the No. 1 lifting seat 404 and the No. 2 lifting seat 4016 are both made of ABS high-strength plastic; the outer wall diameter of the rotating gear 4010 is equal to the outer wall diameter of the swing gear 4012.

[0051] In the above structure, by electrically connecting the control panel 3 and the lifting motor 407, the time speed and rotation direction of the lifting motor 407 are controlled under the action of the control panel 3, so that the No. 1 lifting seat 404 can move up and down along the outer wall of the driving rail 4 under the action of the lifting motor 407, and the scanned thermal imaging image can be fed back to the control panel 3 under the action of the thermal imaging probe 4013, so that the temperature in the inner cavity of the cabinet 1 can be monitored under the action of the control panel 3, and the rotating motor 409 can only rotate half a circle clockwise and then half a circle counterclockwise under the control of the control panel 3, so that the No. 1 swing rod 4011 and the No. 2 swing rod 4014 can cross and reciprocate, thereby achieving a better scanning effect.

[0052] In a preferred embodiment: the outer wall of the locking rod 901 near the limiting ring 902 is beveled, the inner wall diameter of the limiting plate 904 matches the outer wall diameter of the locking rod 901, and the control panel 3 is electrically connected to the locking motor 908.

[0053] In the above structure, a locking rod 901 is set in the inner cavity of the fixing plate 9, and the locking rod 901 can move downward under the action of the driving spring 903 and enter the inner cavity of the locking hole 11. When the outer wall of the locking rod 901 enters the inner cavity of the locking hole 11, it can be said that the outer wall of the cabinet door 2 is completely fitted with the outer wall of the cabinet body 1, ensuring that the cabinet door 2 is completely closed.

[0054] Working principle: during the use of the above-mentioned device, during the normal operation of the cabinet 1, by setting the time, speed and direction of the operation of the lifting motor 407 on the outer wall of the control panel 3, the outer wall of the No. 1 lifting seat 404 can be driven to move up and down along the outer wall of the driving rail 4 under the action of the rotation of the lifting motor 407. During the upward movement of the No. 1 lifting seat 404, the traction rope 4017 will also move upward. At this time, the No. 2 lifting seat 4016 will move downward under the traction of gravity and the traction of the traction rope 4017, so that the lifting plate 408 and the No. 2 lifting seat 4016 can realize alternating up and down movement. When the lifting plate 408 and the No. 2 lifting seat 4016 move up and down, the No. 1 swing rod 4011 and the No. 2 swing rod 4014 will rotate on the rotating motor. Under the action of gear 409 and rotating gear 4010 and swinging gear 4012, alternating motion in the left and right directions is realized, thereby realizing scanning of the electronic components in the inner cavity of cabinet 1 in the horizontal direction, thereby obtaining the thermal imaging image in the inner cavity of cabinet 1 under the action of thermal imaging probe 4013, and feeding back to the outer wall of control panel 3, thereby realizing real-time monitoring of the temperature in the inner cavity of cabinet 1. When performing maintenance on the inner cavity of cabinet 1, it is necessary to open cabinet door 2 from the outer wall of cabinet 1, and it is necessary to close cabinet door 2 after maintenance is completed. When closing cabinet door 2, since the outer wall of locking rod 901 is in an inclined state, the outer wall of locking rod 901 can enter the inner cavity of movable hole 8. If the outer wall of cabinet door 2 is not completely opened when closing cabinet door 2, the outer wall of cabinet door 2 is not completely opened. The locking rod 901 is pushed inwardly in a full direction. At this time, the outer wall of the locking rod 901 cannot enter the inner cavity of the locking hole 11. At this time, since the inner cavity depth of the movable hole 8 is less than the inner cavity depth of the locking hole 11, the locking rod 901 drops to a shorter height. At this time, the outer wall of the trigger plate 906 will not trigger the trigger switch 905. At this time, the trigger switch 905 is not triggered, and the circuit breaker controller cannot receive the electrical signal. At this time, the circuit breaker motor 502 can be started under the action of the circuit breaker controller, and then the slider 504 is moved downward along the outer wall of the driving screw 503 under the action of the circuit breaker motor 502, thereby pulling the support plate 505 and the connecting rod 506 to move, so that the outer wall of the support plate 505 is parallel to the inner wall of the circuit breaker box 5. At this time, the No. 1 lifting seat 404 is downward. During the movement, the outer wall of the No. 1 lifting seat 404 will not be blocked by the support plate 505, so that the No. 1 lifting seat 404 enters the inner cavity of the circuit breaker box 5, triggers the circuit breaker switch 501, and then cuts off the power to the cabinet 1. At this time, since the outer wall of the cabinet door 2 is not completely closed and locked after the maintenance of the cabinet 1, the cabinet 1 will be completely powered off under the action of the circuit breaker switch 501, thereby ensuring the safety of equipment and personnel. If the cabinet door 2 is completely closed, the arc-shaped locking plate 7 will completely enter the inner cavity of the cabinet 1, the outer wall of the locking rod 901 will also enter the inner cavity of the locking hole 11, and the outer wall of the trigger plate 906 will also contact the trigger switch 905, thereby triggering the trigger switch 905, ensuring that the circuit breaker controller can receive the signal.Therefore, the angle of the support plate 505 is not adjusted, so that the support plate 505 is parallel to the top of the circuit breaker box 5, thereby blocking the No. 1 lifting seat 404 from moving downward and blocking the No. 1 lifting seat 404 from triggering the circuit breaker switch 501, thereby ensuring the stable operation of the equipment.
