Specific embodiments

[0022] In order 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 embodiments.

[0023] For the convenience of transporting the middle cabinet, when it is in the carriage, the whole is supported to make the wheels suspended, greatly improving the stability during transportation and avoiding sliding. There are many cable joints in the cable chamber 11. When leakage occurs, an alarm will be automatically issued. As Figures 1-3 shown, a middle cabinet convenient for transportation according to the present utility model includes a base 1 and a middle cabinet body 17. Brakeable universal wheels 2 are installed at the bottom corners of the base 1 through bolts. L-shaped support plates 15 are welded to both ends of the base 1, and electric cylinders 14 are installed on the tops of the L-shaped support plates 15 through mounting seats. A support foot pad 16 is installed on the output shaft of the electric cylinder 14 through bolts. Limit angle plates 3 are welded at the top corners of the base 1, and a middle cabinet body 17 is arranged between the limit angle plates 3;

[0024] On both sides of the top end inside the middle cabinet body 17, an instrument chamber 9 and a busbar chamber 10 are respectively arranged. A circuit breaker chamber 7 is arranged at the lower end of the instrument chamber 9, and a lower chamber 6 is arranged at the lower end of the circuit breaker chamber 7. A cable chamber 11 is arranged at the lower end of the busbar chamber 10. A housing 13 is arranged on one side of the middle cabinet body 17 and on one side of the sealing door of the cable chamber 11. A current sensor 19 is installed in the housing 13 through screws, and a single-chip microcomputer controller 20 is installed at one end of the current sensor 19 through screws. The top of the housing 13 is through screws.

[0025] During use, the middle cabinet is convenient for transportation. When it is in the carriage, the whole is supported to make the wheels suspended, greatly improving the stability during transportation and avoiding sliding. There are many cable joints in the cable chamber 11. When leakage occurs, an alarm will be automatically issued.

[0026] Exemplarily, such as Figure 1 , 3As shown, the utility model also includes that the detection end of the current sensor 19 is located on the inner wall of the cable chamber 11, and the output end and input end of the single-chip controller 20 are electrically connected to the input end of the alarm 12 and the output end of the current sensor 19 through wires.

[0027] When in use, the current sensor 19 detects the current value and transmits it to the single-chip controller 20 for analysis and processing. When the current value exceeds the set value of the single-chip controller 20, the single-chip controller 20 will automatically control the alarm 12 to sound an alarm.

[0028] For example, Figure 1 , 3 As shown, the utility model also includes that U-shaped gripping rods 8 are installed on the upper sides of both ends of the central cabinet 17 by screws, and the cover shell 13 is connected to the central cabinet 17 by a connecting plate 18.

[0029] When in use, the connecting plate 18 facilitates installation and removal of the cover 13 .

[0030] For example, Figure 1 As shown, the utility model also includes that limiting bolts 4 are arranged on both sides of the limiting angle plate 3 and the other ends of the limiting bolts 4 are screwed into the corresponding screw holes of the central cabinet 17 .

[0031] When in use, the central cabinet 17 is conveniently fixed between the limiting angle plates 3, which is convenient for installation and removal.

[0032] For example, Figure 1 , 3 As shown, the utility model also includes that a power storage box 5 is installed on one side of the bottom end of the central cabinet 17 by screws, and the output end of the power storage box 5 is electrically connected to the input end of the electric cylinder 14, the current sensor 19 and the single-chip controller 20 through wires.

[0033] When in use, the power storage box 5 is convenient for supplying power to the electrical equipment to enable it to operate stably.

[0034] When the utility model is in use, the electric cylinder 14 is used to drive the support pad 16 to move downward, so that the support pad 16 is supported on the ground, so that the middle cabinet 17 is stably placed. When the middle cabinet 17 needs to be transported, the electric cylinder 14 is used to drive the support pad 16 to move upward, so that the brakeable universal wheel 2 at the bottom of the base 1 contacts the ground;

[0035] The personnel hold the U-shaped handle 8 to push the middle cabinet 17 for easy transportation. When in the carriage, the electric cylinder 14 is used again to drive the supporting foot pad 16 to move downward to support the whole, which greatly improves the stability during transportation and avoids sliding.

[0036] Since there are many cable joints in the cable chamber 11, when leakage occurs, the current sensor 19 detects the current value and transmits it to the single-chip microcomputer controller 20 for analysis and processing. When it exceeds the set value of the single-chip microcomputer controller 20, the single-chip microcomputer controller 20 will automatically control the alarm 12 to issue an alarm to avoid electric shock accidents.
