Description

Technical Field

[0001] The invention relates to the technical field of electrical cabinets, in particular to a seismic-resistant electrical cabinet. Background Art

[0002] The electrical cabinet is an extremely critical device in the electrical system and plays a vital role. Structurally, it generally has a sturdy cabinet made of high-quality metal materials, such as cold-rolled steel plates, with good strength and stability, which can effectively protect the internal electrical components. The surface of the cabinet has been specially treated to have anti-rust and anti-corrosion functions. The internal layout of the electrical cabinet is reasonable. Through the installation of panels, rails and other components, it provides a stable installation position for various electrical components, including circuit breakers, contactors, relays, fuses, etc., which is convenient for wiring and maintenance. In terms of function, the electrical cabinet is the control center of the entire electrical circuit. It can effectively distribute, protect and control the circuit to prevent overload, short circuit and other faults from damaging electrical equipment. At the same time, it can centrally process and display the signals in the electrical system, which is convenient for operators to monitor and manage. In addition, some electrical cabinets also have good heat dissipation design. Through vents, fans and other means, it ensures that the internal electrical components work stably in a suitable temperature environment to ensure the safe and reliable operation of the electrical system;

[0003] When the electrical cabinet is subjected to vibration, the vibration may loosen the mounting screws of the cabinet, causing the cabinet to deform and affecting its protective performance. The mounting brackets of the internal electrical components may shift due to vibration, causing the connection lines between the components to be stressed, causing the lines to loosen or break. For example, relays and contactors may have poor contact due to looseness. At the same time, vibration can easily cause the wiring terminals to loosen, increase the contact resistance, cause severe local heating, and even generate electric sparks, increasing the risk of electrical fires.

[0042] The heat dissipation mechanism 6 includes a heat dissipation shell 61 and a ventilation pipe 68. The heat dissipation shell 61 penetrates the outer surface of the electrical box 4. The outer surface of the heat dissipation shell 61 is fixedly connected with a dustproof net 64. The side of the dustproof net 64 away from the heat dissipation shell 61 is fixedly connected with a connection box 65.

[0043] A limiting ring 8 is fixedly connected to the upper surface of the electrical box 4, a rotating rod 9 is rotatably connected to the inner cavity of the limiting ring 8, a sealing door panel 10 is fixedly connected to the outer surface of the rotating rod 9, a breathable net 12 runs through the outer surface of the sealing door panel 10, a handle 11 is fixedly connected to the outer surface of the sealing door panel 10, by setting the limiting ring 8, the rotating rod 9 can be limited, so that the rotating rod 9 can rotate in the inner cavity of the limiting ring 8, and then the sealing door panel 10 can close the opening of the electrical box 4, and by setting the handle 11, it is convenient for operators to open and close the sealing door panel 10, the limiting mechanism 3 includes a track frame 31 and a sliding plate 32, the track frame 31 is symmetrically fixedly connected to both sides of the outer side of the electrical box 4, and the sliding plate 32 is fixedly connected to the connecting frame 2 away from the frame. 1, the outer side surface of the sliding plate 32 is fixedly connected with a sliding rod 33, and the sliding rod 33 is slidably connected to the inner wall of the track frame 31. By setting the track frame 31, the sliding rod 33 can be limited, so that the sliding rod 33 can produce an effect of vertical up and down movement in the inner cavity of the track frame 31, thereby limiting the movement route of the sliding plate 32, and finally limiting the movement position of the electrical box 4. The limiting mechanism 3 also includes a U-shaped tube 36, which passes through the outer surface of the electrical box 4. One end of the U-shaped tube 36 located on the outer surface of the electrical box 4 is fixedly connected with a sealing box 37, and the inner wall of the sealing box 37 is slidably connected with a first piston 35, and the lower surface of the first piston 35 is fixedly connected with a first support rod 34, and the bottom end of the first support rod 34 is fixedly connected. The U-shaped tube 36 and the sealing box 37 are connected to the upper surface of the sliding plate 32, so that the internal air can be sealed, and when the first piston 35 moves upward or downward, the internal air can change. The cross section of the sealing box 37 is rectangular, and the inner diameter of the sealing box 37 is much larger than the U-shaped tube 36.

When in use, the operator places the electrical equipment in the inner cavity of the electrical box 4, then pulls the handle 11 and rotates the rotating rod 9 in the inner cavity of the limiting ring 8, and the device causes the sealing door plate 10 to close the opening of the electrical box 4. When the electrical box 4 is vibrated, the electrical box 4 moves downward due to the vibration, thereby causing the sliding rod 33 to move in the inner cavity of the track frame 31, thereby causing the electrical box 4 to produce stable vertical movement. When the vibration amplitude is large, the moving distance of the first piston 35 in the inner cavity of the sealing box 37 becomes larger.Then, the second piston 38 drives the second support rod 39 and the sealing cover 311 to move downward a large distance, and finally the sealing cover 311 covers the hole of the exhaust box 62.

By setting the one-way bearing 615, only one-way rotation can be generated between the rotating block 616 and the rotating column 613.

When the electrical box 4 is vibrated, the electrical box 4 moves downward due to the vibration, thereby causing the sliding rod 33 to move in the inner cavity of the track frame 31, so that the electrical box 4 can produce stable vertical movement. When the vibration amplitude is large, the first piston 35 moves a larger distance in the inner cavity of the sealing box 37, thereby causing the second piston 38 to drive the second support rod 39 and the sealing cover 311 to move downward a larger distance, and finally the sealing cover 311 covers the hole of the exhaust box 62; when the electrical box 4 moves vertically up and down due to vibration, the gear column 614 will mesh with the rack 610, thereby causing the rotating column 613 to rotate.
