Description

Technical Field

[0001] This utility model relates to the field of grounding terminal protection technology, and in particular to an anti-oxidation and anti-rust protective cover for the grounding terminal of electrical equipment in steel smelting. Background Technology

[0002] In steel smelting workshops, reliable grounding of electrical equipment is the lifeline for ensuring personal safety and normal equipment operation. The grounding system is usually connected to the equipment casing or grounding trunk line through grounding busbar.

[0003] Currently, grounding bars are usually directly exposed or simply coated with anti-rust paint. However, the steel smelting environment is typically characterized by high temperature, high humidity, and acidic gases such as sulfur or chlorine, which easily lead to electrochemical corrosion and oxidation. This can cause the paint layer to break easily, and the oxidation of the metal substrate can form a rust layer, resulting in increased grounding resistance, affecting the conduction of leakage current, and making subsequent maintenance inconvenient. Therefore, we propose an anti-oxidation and anti-rust protective cover for the grounding terminal of electrical equipment in steel smelting to solve the above problems. Utility Model Content

The sides of the bottom frame and the cover frame are respectively provided with cable outlet holes, and cable outlet pipes are fixedly connected to the inner walls of the cable outlet holes. A fixing block is fixedly connected to the back of the cover frame, and a slot is provided inside the fixing block. The inner wall of the slot is connected to a connecting plate by a connecting spring, and a limit plate is fixedly connected to the top of the connecting plate. A slot adapted to the limit plate is provided on the side of the cover frame.

[0007] Preferably, a linkage block is fixedly connected to the bottom end of the connecting plate, and the fixed block has a moving groove adapted to the fixed block inside.

[0008] Preferably, a mating plate is fixedly connected to the bottom end of the cover frame, and a mating groove adapted to the mating plate is provided on the top of the bottom frame.

[0009] Preferably, a mounting plate is fixedly connected to the top of the grounding bar, and the sides of the mounting plates that are close to each other are connected to the outer wall of the bottom frame by bolts.

[0010] Preferably, the inner wall of the outlet tube is glued with a rubber sleeve, and the inner diameter of the opening of the rubber sleeve is larger than the inner diameter of the center.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Reference Figure 1-6 An anti-oxidation and anti-rust protective cover for the grounding terminal of electrical equipment in steel smelting includes a grounding bar 1. Two sets of connectors 14 are symmetrically connected to the bottom end of the grounding bar 1. A bottom frame 2 is provided above the grounding bar 1, and a cover frame 3 is provided above the bottom frame 2. The bottom frame 2 and the cover frame 3 are respectively provided with wire outlet holes 15, and the inner wall of the wire outlet hole 15 is fixedly connected with a wire outlet pipe 4. The wire outlet hole 15 and the wire outlet pipe 4 can meet the wire outlet requirements through their cooperation. A fixing block 5 is fixedly connected to the back of the cover frame 3, and a slot is provided inside the fixing block 5. The inner wall of the slot is connected to a connecting plate 7 through a connecting spring 6, and a limit plate 8 is fixedly connected to the top of the connecting plate 7. A slot adapted to the limit plate 8 is provided on the side of the cover frame 3.

[0025] Furthermore, refer to Figure 4 It can be seen that the bottom end of the connecting plate 7 is fixedly connected to the linkage block 9, and the inside of the fixing block 5 is provided with a moving groove that matches the fixing block 5. Through the cooperation of the linkage block 9 and the moving groove, the lateral guidance of the connecting plate 7 can be realized.

[0026] Furthermore, refer to Figure 2 It can be seen that the bottom end of the cover frame 3 is fixedly connected to the docking plate 13, and the top of the bottom frame 2 is provided with a docking groove that matches the docking plate 13. During use, the pre-positioning operation of the cover frame 3 can be realized through the cooperation of the docking plate 13 and the moving groove, so as to facilitate the subsequent use of the limiting plate 8 to fix the cover frame 3, and effectively ensure the tightness of the connection between the bottom frame 2 and the cover frame 3.

[0027] Furthermore, refer to Figure 2 and Figure 4 It can be seen that the top of the grounding bar 1 is fixedly connected to the mounting plate 12, and the side of the mounting plate 12 that is close to each other is connected to the outer wall of the bottom frame 2 by bolts. Through the cooperation of the mounting plate 12 and the bolts, the disassembly and assembly requirements between the bottom frame 2 and the mounting plate 12 can be realized, thereby effectively replacing or cleaning and maintaining the damaged bottom frame 2.

[0028] Furthermore, refer to Figure 3It can be seen that the inner wall of the outlet tube 4 is glued with a rubber sleeve 11, and the inner diameter of the opening of the rubber sleeve 11 is larger than the inner diameter of the center. The inner diameter of the rubber sleeve 11 is matched with the outer diameter of the wire harness through the rubber material, so as to ensure the tightness and sealing of the wire harness when it is inserted into the outlet tube 4. Since the opening of the rubber sleeve 11 is large, it is convenient to insert the wire harness.

[0029] Furthermore, refer to Figure 1 It can be seen that a rectangular groove is provided on the top of the cover frame 3, and an observation window 10 is fixedly connected to the inner wall of the rectangular groove. Through the transparent observation window 10, staff can easily check the working status of the bolts inside the grounding bar 1 and carry out timely maintenance.

[0030] Furthermore, refer to Figure 2 It can be seen that there are two sets of mounting plates 12 and docking plates 13, and the two sets of mounting plates 12 and docking plates 13 are symmetrically distributed about the central axis of the cover frame 3. The two sets of mounting plates 12 can effectively ensure the tightness of the connection between the bottom frame 2 and the grounding bar 1, and the two sets of docking plates 13 can ensure the tightness of the connection between the bottom frame 2 and the cover frame 3.

[0031] Working Principle: When using this utility model, the operator can first place the grounding busbar 1 in a suitable position, and then insert the bolt into the inside of the connector 14 to fix the connector 14 and the grounding busbar 1. Then, the operator can insert the grounding wire connected to the electrical equipment into the outlet pipe 4 and bolt it to the grounding busbar 1. After the bolting is completed, the operator can pull the connecting plate 7 horizontally to drive the limiting plate 8 to bear force at the same time. Then, the operator can cover the top of the bottom frame 2 with the cover frame 3. After the cover is completed, the operator can stop pulling the connecting plate 7, so that the limiting plate 8 connected inside it can be inserted into the slot opened on the back of the cover frame 3 to achieve the limiting and fixing of the cover frame 3. Through the cooperation of the bottom frame 2 and the cover frame 3, the grounding busbar 1 and the internal bolts can be protected, thereby effectively slowing down the oxidation and corrosion rate and ensuring the safety of the grounding process. The above is the complete working principle of this utility model.
