When describing the embodiments of the present invention in detail, for the sake of convenience, the cross-sectional diagrams showing the device structure will not be partially enlarged according to the general scale, and the schematic diagrams are only examples, which should not limit the scope of protection of the present invention. In addition, in actual production, the three-dimensional dimensions of length, width and depth should be included.

[0032] Example 1, reference Figures 1 to 10 , which is the first embodiment of the present invention, provides a safety monitoring device for use in a switch cabinet, the device comprising a monitoring component 100, including a basic component 101, a connecting component 102 arranged on the basic component 101, and an alarm component 103 arranged on the connecting component 102.

[0033] Among them, the basic component 101 is mainly used for opening and closing, controlling and protecting electrical equipment in the process of power generation, transmission, distribution and power conversion in the power system. The connecting component 102 is used to connect the monitoring device and the basic component 101, so that the monitoring equipment can perform detection in real time, so that the alarm component can directly operate to prompt on-site personnel after exceeding the safety distance.

[0034] Preferably, the basic component 101 and the monitoring device are connected together through the connecting component 102, so that the monitoring device covers the live busbar inside. When the maintenance personnel's arm exceeds the installation distance, the alarm component 103 issues a warning to remind the on-site personnel to prevent accidents.

[0035] Furthermore, the adjusting component 200 includes a control component 201 disposed on the connecting component 102 , a switching component 202 disposed on the control component 201 , and a lifting component 203 disposed on the switching component 202 .

[0036] Among them, the control component 201 is used to control the operation of the lifting component 203, so that the lifting component 203 can rise and fall, driving the signal transmitting end 103c and the signal receiving end 103d to rise and fall, so that they can block the live bus to prevent accidents. The switching component 202 is used to control the component 201, so that the control component 201 switches from controlling the lifting component 203 to the sliding component 301.

[0037] Preferably, by controlling the operation of the switching component 202, the control component 201 can switch back and forth between the lifting component 203 and the sliding component 301, respectively controlling different parts to achieve different effects. The operation of the lifting component 203 drives the signal transmitting end 103c and the signal receiving end 103d to move up and down, so that the device can cover the live bus on the rear side.

[0038] Furthermore, the unlocking component 300 includes a sliding component 301 disposed on the control component 201 , a limiting component 302 disposed on the switching component 202 , and an unlocking component 303 disposed on the limiting component 302 .

The limiting component 302 is used to limit the control component 201, so that the control component 201 is connected to the lifting component 203 or the sliding component 301 respectively. The unlocking component 303 is set to unlock the limiting component 302 to facilitate the operation of the switching component 202.

[0040] In summary: through the operation of the unlocking component 303, the switching component 202 drives the control component 201 to operate with the lifting component 203 and the sliding component 301 respectively, so that the control component 201 can drive the signal transmitting end 103c and the signal receiving end 103d to move up and down through the lifting component 203, so that they cover the live bus to prevent accidents, and then control the operation of the sliding component 301, so that the sliding component 301 operates, so that the protective shell 102e is in a vertical state, which is convenient for docking.

[0041] Example 2, reference Figures 1 to 8 , which is the second embodiment of the present invention, comprises: a basic component 101 comprises a switch cabinet body 101a, a control unit 101b arranged on the switch cabinet body 101a, a cabinet door 101c arranged on the switch cabinet body 101a, and a support rod 101d arranged inside the switch cabinet body 101a.

[0042] Among them, the switch cabinet body 101a is used to protect the control unit 101b, so that the control unit 101b is protected. The control unit 101b is used to open and close, control and protect electrical equipment during power transmission, distribution and power conversion in the power system.

When there are no obstacles, the equipment operates normally. When the signal at the transmitting end is blocked, the buzzer sounder operates to remind on-site personnel.

[0048] Preferably, the signal transmitting end 103c and the signal receiving end 103d are arranged so that the monitoring area covers the area of ​​the live busbar. When the maintenance personnel are cleaning or repairing, if the arm exceeds the safe distance, the arm will block the signal sent by the signal transmitting end 103c. When the receiving end cannot receive the signal, the buzzer sounder will sound an alarm to alert the on-site personnel, thereby preventing the occurrence of danger.

[0049] Furthermore, the control assembly 201 includes a rotating member 201a disposed inside the protective shell 102e, a threaded rod 201b disposed on the rotating member 201a, and a lifting rod 201c disposed on the threaded rod 201b.

[0051] Preferably, the lifting rod 201c is driven to rotate by the rotating member 201a, so that the lifting rod 201c drives the internal lifting block to move upward, thereby completing the adjustment of the equipment detection area so that the detection area covers the area where the live bus exists.

[0052] Furthermore, the lifting assembly 203 includes a spiral groove 203a arranged on the lifting rod 201c, a lifting plate 203b arranged inside the protective shell 102e, a connecting groove 203c arranged on the lifting plate 203b, and a limiting point 203d arranged inside the connecting groove 203c.

[0053] The spiral groove 203a is used to control the movement of the limiting point 203d, and the lifting plate 203b moves up and down in cooperation with the spiral groove 203a and the limiting point 203d. The connection groove 203c is used to facilitate the lifting rod 201c to control the movement of the lifting plate 203b.

[0054] Preferably, by controlling the rotation of the rotating member 201a, the rotating member 201a drives the lifting rod 201c to rotate, thereby causing the spiral groove 203a to rotate. The rotation of the spiral groove 203a controls the movement of the limiting point 203d inside it, thereby causing the limiting point 203d to move up and down, driving the lifting plate 203b to move, thereby causing the signal transmitting end 103c and the signal receiving end 103d to move together with it, thereby realizing the adjustment of the detection area.
