Description

Technical Field

[0001] The utility model relates to the technical field of electrical cabinets, in particular to an electrical cabinet with maintenance protection function. Background Art

[0002] An electrical cabinet is a device made of steel materials, mainly used to protect electrical components to work properly. It is widely used in various industries such as chemical industry, environmental protection, electric power, metallurgy, industry, nuclear power, fire safety monitoring, and transportation. When a fault occurs in the electrical cabinet, it is necessary to repair the electrical cabinet. During the repair process of the traditional electrical cabinet, maintenance personnel need to cut off the power inside and outside the device in advance and then carry out the repair. However, during the repair, there are often safety hazards because maintenance personnel forget to cut off the power. Content of the Utility Model

[0003] Aiming at the defects in the prior art, the purpose of the utility model is to provide an electrical cabinet with maintenance protection function, which can prevent maintenance personnel from forgetting to cut off the power during maintenance and causing safety accidents, and is relatively simple to operate.

[0004] The technical solution of the utility model is: an electrical cabinet with maintenance protection function, including a base, on which an electrical cabinet body is placed. A rotating shaft is rotatably connected to the side of the electrical cabinet body, and a cabinet door is fixedly connected to the rotating shaft. A wiring component is arranged on the electrical cabinet body.

[0005] As a preferred technical solution of the utility model, the wiring component includes a wiring box, which is fixedly connected inside the electrical cabinet body. Four wiring heads are arranged on the wiring box. Two wiring heads on the same side are in a group. A pressing connection head is slidably connected to the top of the wiring box. Two return springs are connected between the pressing connection head and the wiring box.

[0006] As a preferred technical solution of the utility model, it further includes a transmission rod, which is slidably connected to the electrical cabinet body and is also slidably connected to the wiring box. A sliding connection head is fixedly connected to the top of the transmission rod, and the sliding connection head contacts the wiring head.

[0007] As a preferred technical solution of the utility model, it further includes a limiting ring. Two limiting rings are fixedly connected to the rotating shaft, and the two limiting rings are arranged in a staggered manner. A clamping plate is fixedly connected to the transmission rod, and the bottom of the clamping plate contacts the top of the upper limiting ring.

[0008] As a preferred technical solution of the present utility model, it further includes a sleeve rod, the sleeve rod is slidably connected to the bottom of the transmission rod, a first compression spring is connected between the transmission rod and the sleeve rod, a pedal is slidably connected to the base, four second compression springs are connected between the pedal and the base, and the bottom of the sleeve rod is fixedly connected to the pedal.

[0009] Beneficial effects: 1. When the pedal is stepped on and descends, the second compression spring is compressed. The descent of the pedal drives the sleeve rod to descend. Since one of the limit rings contacts the clamping plate, the transmission rod is limited. When the pedal descends, the first compression spring will be stretched. When the maintenance personnel open the cabinet door, the cabinet door drives the rotating shaft to rotate, and the rotation of the rotating shaft makes the limit ring rotate, and the limit ring and the clamping plate are separated. The transmission rod is no longer limited, and the reset of the first compression spring drives the transmission rod to descend. The descent of the transmission rod makes the sliding connector and the connection terminal separate, so that the inside of the electrical cabinet is powered off. Through this setting, it can prevent the maintenance personnel from forgetting to cut off the power during maintenance and causing safety accidents.

[0010] 2. After the maintenance personnel complete the maintenance, they can press the pressing connector. The pressing connector descends, and the reset spring is compressed. The pressing connector contacts the connection terminal, so that the internal and external circuits of the electrical cabinet are connected, so that it can be observed whether the repaired part is repaired. In this way, the maintenance personnel do not need to close the door to check whether the maintenance is successful, making the operation relatively simple. Description of the Drawings

Detailed implementation mode

[0018] The present utility model will be further described in detail below in conjunction with the attached drawings and specific implementation modes, but the protection scope and application scope of the present utility model are not limited.

[0019] Embodiment 1: An electric cabinet with maintenance protection function, as Figures 1 - 6 shown, includes a base 1, an electric cabinet body 2 is placed on the base 1, a rotating shaft 3 is rotatably connected to the side of the electric cabinet body 2, a cabinet door 4 is fixedly connected to the rotating shaft 3, and a wiring component is arranged on the electric cabinet body 2.

[0020] The wiring component includes a wiring box 7, the wiring box 7 is fixedly connected inside the electric cabinet body 2, four wiring heads 8 are arranged on the wiring box 7, two wiring heads 8 on the same side are in a group, a pressing connection head 9 is slidably connected to the top of the wiring box 7, and two return springs 10 are connected between the pressing connection head 9 and the wiring box 7, and the return springs 10 are used to drive the pressing connection head 9 to reset.

[0021] It further includes a transmission rod 12, the transmission rod 12 is slidably connected to the electric cabinet body 2, the transmission rod 12 is slidably connected to the wiring box 7, a sliding connection head 11 is fixedly connected to the top of the transmission rod 12, and the sliding connection head 11 contacts the wiring head 8, so that the internal and external circuits of the electric cabinet are connected.

[0022] It further includes a limiting ring 13, two limiting rings 13 are fixedly connected to the rotating shaft 3, the two limiting rings 13 are arranged in a staggered manner, a clamping plate 14 is fixedly connected to the transmission rod 12, the bottom of the clamping plate 14 contacts the top of the limiting ring 13 located above, and the clamping plate 14 is used to limit the transmission rod 12.

[0023] It further includes a sleeve rod 15, the sleeve rod 15 is slidably connected to the bottom of the transmission rod 12, a first pressure spring 16 is connected between the transmission rod 12 and the sleeve rod 15, the first pressure spring 16 is used to drive the transmission rod 12 to reset, a pedal 17 is slidably connected to the base 1, four second pressure springs 18 are connected between the pedal 17 and the base 1, and the bottom of the sleeve rod 15 is fixedly connected to the pedal 17.

[0024] In practical applications, initially, the connection terminal 8 and the sliding connection head 11 are in contact, enabling the internal and external circuits of the electrical cabinet body 2 to be connected. When a fault occurs inside the electrical cabinet body 2, maintenance personnel repair the electrical cabinet body 2. The maintenance personnel stand in front of the electrical cabinet body 2, and the pedal 17 is stepped on and descends. The second pressure spring 18 is compressed. The descent of the pedal 17 drives the sleeve rod 15 to descend. Since one of the limit rings 13 contacts the clamping plate 14, the transmission rod 12 is limited. The descent of the pedal 17 will cause the first pressure spring 16 to stretch. When the maintenance personnel open the cabinet door 4, the cabinet door 4 drives the rotating shaft 3 to rotate. The rotation of the rotating shaft 3 causes the limit ring 13 to rotate. One of the limit rings 13 disengages from the clamping plate 14, and the transmission rod 12 is no longer limited. The reset of the first pressure spring 16 drives the transmission rod 12 to descend. The descent of the transmission rod 12 causes the sliding connection head 11 and the connection terminal 8 to disengage, thus cutting off the power supply inside the electrical cabinet body 2. After the cabinet door 4 is fully opened, the other limit ring 13 will rotate above the clamping plate 14, causing the transmission rod 12 to be limited. In this way, when the staff is performing maintenance and not stepping on the pedal 17, the sliding connection head 11 will not move upward, which can prevent the inside of the electrical cabinet body 2 from being electrified during maintenance and improve the safety during maintenance. When the maintenance is completed and the staff no longer step on the pedal 17, the second pressure spring 18 resets, and the second pressure spring 18 drives the sleeve rod 15 to rise. Since the transmission rod 12 is limited, the first pressure spring 16 is compressed. Then the maintenance personnel close the cabinet door 4. The rotation of the cabinet door 4 causes the rotating shaft 3 to rotate. The rotation of the rotating shaft 3 drives the limit ring 13 to rotate, causing the lower limit ring 13 to disengage from the clamping plate 14. The reset of the first pressure spring 16 drives the transmission rod 12 to rise. The transmission rod 12 drives the sliding connection head 11 to rise, causing the sliding connection head 11 and the connection terminal 8 to contact again, thereby enabling the internal and external circuits of the electrical cabinet body 2 to be electrified and completing the maintenance. Through such a setting, it can prevent maintenance personnel from forgetting to cut off the power and causing safety accidents during maintenance.

[0025] After the maintenance personnel complete the maintenance, the pressing connection head 9 can be pressed. The pressing connection head 9 descends, and the reset spring 10 is compressed. The pressing connection head 9 contacts the connection terminal 8, enabling the internal and external circuits of the electrical cabinet to be connected, so that it can be observed whether the repaired area is repaired. In this way, the maintenance personnel can check whether the maintenance is successful without closing the door, making the operation relatively simple. After the maintenance personnel no longer press the pressing connection head 9, the reset spring 10 resets and drives the pressing connection head 9 to reset, causing the pressing connection head 9 and the connection terminal 8 to disengage.

[0026] The above has described the embodiments of the present invention in detail in conjunction with the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the gist of the present invention.
