Description

Technical Field

[0001] The utility model relates to the technical field of incoming line protection, in particular to an incoming line protection frame for an electrical control cabinet. Background Art

[0002] The electrical control cabinet is a combination of switchgear, measuring instruments, protective electrical appliances and auxiliary equipment assembled in a closed or semi-closed metal cabinet or on a screen according to the electrical wiring requirements. Its layout should meet the requirements for normal operation of the power system and should not endanger the safety of people and surrounding equipment. During normal operation, the circuit can be connected or disconnected with the help of manual or automatic switches.

[0003] Electrical control cabinets are usually connected to the outside from the bottom. After the wiring is completed, the wire opening at the bottom needs to be sealed to prevent insects and moisture. Currently, the sealing is mainly done through the cover plate, but the wires inside the electrical control cabinet are thick and thin, and the wire holes on the cover plate are difficult to adapt to wires of different thicknesses. Utility Model Content

[0004] The utility model provides an inlet protection frame for an electrical control cabinet, which can play a good covering role on wires of different thicknesses and ensure the sealing performance.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A line inlet protection frame for an electrical control cabinet comprises a base plate, a line inlet port being formed on the bottom outer wall of the base plate, a vertical plate being fixed at one end of the top outer wall of the base plate, a slide groove being formed on one side outer wall of the vertical plate, a fixing component being installed on the inner wall of the slide groove, movable grooves being formed on both ends of the top outer wall of the base plate, movable blocks being slidably connected to the inner walls of the two movable grooves, clamping frames being fixed to the top outer walls of the two movable blocks, sponge blocks being fixed to the bottom of the inner walls of the two clamping frames, sealing putty being placed on the top of the inner walls of the two clamping frames, and a card block being fixed to the outer wall of one side of the two clamping frames.

[0007] Through the above scheme, the base plate can be fixed above the wire inlet opening on the inner wall at the bottom of the electrical control cabinet, and the wire inlet opening at the bottom of the electrical control cabinet can be blocked by the base plate. The wire can only enter the electrical control cabinet from the wire inlet on the base plate. The moving block moves in the moving groove, which can drive the clamping frame to move. After the wire is entered, the two clamping frames can be merged together and fixed by the fixing assembly. The wire is coated with sponge blocks and sealing putty, and the wire inlet is sealed with sponge blocks and sealing putty, which plays a sealing role on the bottom of the electrical control cabinet. The sponge block and sealing putty can play a good coating role on wires of different thicknesses to ensure sealing.

[0008] Preferably, the fixing assembly includes a sliding rod, a sliding block sleeved on the sliding rod, a spring sleeved on the sliding rod, and a bracket fixed on an outer wall of one side of the sliding block.

[0009] Through the above scheme, in the process of merging the two clamping frames, the card frame can be pulled up by hand, and the slider can be driven to move up to squeeze the spring. After the two clamping frames are merged, the hand can be released. Under the action of gravity and spring recovery, the card frame automatically resets and wraps the two card blocks inside, so that the two clamping frames are fixed together.

[0010] Preferably, the cross-sections of the moving groove and the moving block are both "T"-shaped structures.

[0011] Through the above solution, the moving block will not fall in the moving groove.

[0012] Preferably, the slider is slidably connected to the inner wall of the slide groove, a through hole is opened on the outer wall at the top of the slider, and the slider is sleeved on the sliding rod.

[0013] Through the above scheme, the installation of the slider is completed.

[0014] Preferably, the clamping frame is a "C"-shaped structure.

[0015] Through the above solution, the two clamping frames can be combined into a frame.

[0016] Preferably, the spring is located above the slider.

[0017] Through the above solution, the spring can be compressed when the slider moves upward.

[0018] The beneficial effects of the utility model are:

[0019] The base plate can be fixed above the wire entry opening on the bottom inner wall of the electrical control cabinet, and the wire enters the electrical control cabinet from the wire entry port on the base plate. After the wire is entered, the two clamping frames can be merged together and fixed by a fixing assembly. The wire is coated with a sponge block and sealing putty, and the wire entry port is sealed with the sponge block and sealing putty to seal the bottom of the electrical control cabinet. The sponge block and sealing putty can cover wires of different thicknesses well to ensure sealing. BRIEF DESCRIPTION OF THE DRAWINGS
