Description

Technical Field

[0001] The utility model relates to the field of explosion-proof boxes, in particular to an explosion-proof integrated control box with a self-protection device for inspection, repair and maintenance. Background Technique

[0002] An explosion-proof control box is a distribution box with explosion-proof function, mainly used in explosive hazardous environments, such as flammable and explosive places in petroleum, chemical industry, medicine, military industry, etc. Its main function is to monitor and control the production process to ensure the stability and safety of the production process.

[0003] A plurality of relays for controlling electronic devices are installed inside the control box. However, when it is necessary to repair the relays inside the control box, during the process of opening the door, external flammable and explosive gases or dust are likely to enter the inside of the control box, and electric sparks will be generated during the operation of the relays. Once the electric sparks come into contact with the explosive gases, a violent explosion will occur, resulting in major accidents. Content of the Utility Model

[0004] The purpose of the utility model is to solve the defects existing in the prior art, and to provide an explosion-proof integrated control box with a self-protection device for inspection, repair and maintenance.

[0005] To achieve the above purpose, the utility model adopts the following technical scheme: an explosion-proof integrated control box with a self-protection device for inspection, repair and maintenance, including a cabinet body, wherein a limiting groove is opened on the inner wall of the cabinet body, and the number of the limiting grooves is two. A moving plate is arranged inside the cabinet body. Limiting blocks are fixedly connected to the outer wall of the moving plate, and the number of the limiting blocks is two. The two limiting blocks are respectively located inside the two limiting grooves. Chute grooves are opened on the outer wall of the moving plate, and the number of the chute grooves is two. Pulley grooves are opened at the inner bottom of the cabinet body, and the number of the pulley grooves is two. Pulley frames are fixedly connected to the bottom of the moving plate, and the number of the pulley frames is two. The two pulley frames are respectively located inside the two pulley grooves. Pulleys are movably connected to the inner walls of the two pulley frames. The cabinet body is connected with a cabinet door through a hinge. Connecting rods are fixedly connected to the inner wall of the cabinet door, and the number of the connecting rods is two. Sliders are installed inside the two chute grooves. A U-shaped plate is fixedly connected to the outer wall of the slider. The other end of the connecting rod is movably connected to the inner wall of the U-shaped plate. Power-off buttons are fixedly connected to the front ends of the inner walls of the two limiting grooves.

[0006] As a further description of the above technical solution:

[0007] A flap groove is opened on the rear outer wall of the cabinet body. A flap is installed inside the flap groove. The flap is magnetically connected to the inner wall of the flap groove.

[0008] As a further description of the above technical solution:

[0009] The inner wall of the cabinet body is provided with heat dissipation grooves, and the number of heat dissipation grooves is multiple.

[0010] As a further description of the above technical solution:

[0011] A rain shield is fixedly connected to the outer wall of the cabinet body, and the number of rain shields is multiple. The multiple rain shields respectively correspond to the multiple heat dissipation grooves.

[0012] As a further description of the above technical solution:

[0013] Support feet are fixedly connected to the bottom of the cabinet body, and the number of support feet is multiple.

[0014] As a further description of the above technical solution:

[0015] The two limiting grooves are respectively located at the upper and lower ends of the outer wall of the moving plate, and a handle is installed on the outer wall of the cabinet door.

[0016] The utility model has the following beneficial effects:

[0017] 1. When maintenance is carried out, when the cabinet door is opened, the cabinet door rotates counterclockwise with the right side as the center. When the cabinet door rotates, the two connecting rods connected to the inner wall of the cabinet door rotate counterclockwise at the same time. The other ends of the two connecting rods drive the U-shaped plate and the slider to move. The slider moves along the chute inside the moving plate, thereby pulling the moving plate to move outward. At the same time, the two pulleys connected to the bottom of the moving plate slide along the two pulley grooves opened on the inner bottom of the cabinet body. The limiting blocks connected to the outer walls on both sides of the moving plate move along the limiting grooves opened on the inner wall of the cabinet body. The limiting blocks move along the limiting grooves until they contact the power-off button, thereby powering off the entire cabinet body. At this time, the cabinet door is also completely opened, which is convenient for maintenance personnel to maintain the electrical components on the moving plate. At the same time, in the power-off state, it can avoid flammable gases or dust from entering the cabinet body and causing an explosion. In the existing control cabinet, during the door opening process, external combustible and explosive gases or dust are likely to enter the inside of the control box, and electric sparks will be generated during the operation of the relay. Once the electric sparks come into contact with the explosive gas, a violent explosion will occur and cause major accidents. This control cabinet is convenient for maintenance personnel to maintain the electrical components on the moving plate and can also avoid flammable gases or dust from entering the cabinet body and causing an explosion.

[0018] 2. By opening a flap groove on the rear side of the outer wall of the cabinet, the flap groove is movably connected with a flap through a hinge. When the internal air pressure is too high, the flap will be pushed open, so that the internal high-pressure gas is discharged, avoiding the explosion of the cabinet door caused by excessive air pressure. At the same time, multiple heat dissipation grooves are opened on the inner wall of the cabinet, and multiple rain shields are connected to the outer wall of the cabinet, playing a role in heat dissipation.

When the cabinet door 9 rotates, the two connecting rods 10 connected to the inner wall of the cabinet door 9 rotate counterclockwise simultaneously. The other ends of the two connecting rods 10 drive the U-shaped plate 12 and the slider 11 to move. The slider 11 moves along the chute 5 inside the moving plate 3, thereby pulling the moving plate 3 to move outward. At the same time, the two pulleys 8 connected to the bottom of the moving plate 3 slide along the two pulley grooves 6 opened on the inner bottom of the cabinet body 1. The limiting blocks 4 connected to the outer walls on both sides of the moving plate 3 move along the limiting grooves 2 opened on the inner wall of the cabinet body 1. The limiting blocks 4 move along the limiting grooves 2 until they contact the power-off button 13, thereby powering off the entire cabinet body 1. At this time, the cabinet door 9 is also fully opened, facilitating maintenance personnel to maintain the electrical components on the moving plate 3. A flap groove 14 is provided on the rear side of the outer wall of the cabinet body 1. The flap groove 14 is movably connected to a flap 15 through a hinge. When the internal air pressure is too high, it will push open the flap 15, thereby discharging the internal high-pressure gas.
