Description

Technical Field

[0001] This utility model relates to the field of explosion-proof electrical products technology, and in particular to a detachable wire-passing encapsulation device for explosion-proof electrical products. Background Technology

[0002] Explosion-proof electrical products, as the name suggests, are electrical products designed to prevent explosions in environments containing mixtures of explosive hazardous gases. In my country, explosion-proof electrical equipment is broadly divided into two categories: one is called mining explosion-proof electrical products, mainly used in coal mines and other mining areas where explosive gases such as methane are present; the other is called factory explosion-proof electrical products, mainly used in all other locations besides mines and coal mines. These include industries such as petroleum, chemical, textile, pharmaceutical, and military, and include both gas explosion-proof and dust explosion-proof electrical products.

[0003] Conventional explosion-proof electrical products on the market use connecting joints for wire sealing, and then glue is directly poured into the connecting joints. The connecting joints are spliced ​​with the explosion-proof cavity by welding, which makes it impossible to disassemble, repair or replace the connecting joints, and thus fails to meet the explosion-proof structure requirements of explosion-proof electrical products.

[0004] Therefore, we propose a detachable wire-passing encapsulation device for explosion-proof electrical products. Utility Model Content

[0005] The present invention aims to solve the technical problems existing in the prior art and provide a detachable wire-passing encapsulation device for explosion-proof electrical products.

[0010] Preferably, the inner wall of the explosion-proof hollow bolt is provided with a cable.

[0011] Preferably, the inner wall of the explosion-proof hollow bolt, located on the outer wall of the cable, is filled with explosion-proof sealant.

[0012] This utility model provides a detachable wire-passing encapsulation device for explosion-proof electrical products. It offers the following advantages: by incorporating a first detachable wire-passing encapsulation connecting joint assembly and a second detachable wire-passing encapsulation connecting joint assembly, these assemblies not only provide a fixed connection between the first and second explosion-proof housings, but also allow for individual removal and replacement of the explosion-proof hollow bolts by cutting the cable when maintenance or replacement is needed. This eliminates the need to replace the entire first and second explosion-proof housings, reducing overall maintenance costs and meeting the explosion-proof structural requirements of explosion-proof electrical products.

[0023] Example 1: A detachable wire-passing encapsulation device for explosion-proof electrical products, such as... Figure 1As shown, the device includes a first explosion-proof housing 10, a second explosion-proof housing 11 on the front side of the first explosion-proof housing 10, a first detachable wire-passing encapsulated connecting joint assembly 12 on the left side of the front end of the inner wall of the first explosion-proof housing 10, and the front end of the outer wall of the first detachable wire-passing encapsulated connecting joint assembly 12 is movably connected to the left side of the rear end of the inner wall of the second explosion-proof housing 11. A second detachable wire-passing encapsulated connecting joint assembly 13 on the right side of the front end of the inner wall of the first explosion-proof housing 10, and the structure of the second detachable wire-passing encapsulated connecting joint assembly 13 is the same as that of the first detachable wire-passing encapsulated connecting joint assembly 12. The front end of the outer wall of the second detachable wire-passing encapsulated connecting joint assembly 13 is movably connected to the left side of the rear end of the inner wall of the second explosion-proof housing 11. The right rear end of the inner wall of the explosion-proof housing 11 is movably connected by a first detachable wire-passing encapsulated connecting joint assembly 12 and a second detachable wire-passing encapsulated connecting joint assembly 13. The first detachable wire-passing encapsulated connecting joint assembly 12 and the second detachable wire-passing encapsulated connecting joint assembly 13 not only provide a fixed connection between the first explosion-proof housing 10 and the second explosion-proof housing 11, but also allow for individual removal and replacement of the explosion-proof hollow bolt 14 by cutting the cable 16 when maintenance or replacement is required, without having to replace the entire first explosion-proof housing 10 and the second explosion-proof housing 11. This reduces the overall maintenance cost and meets the explosion-proof structure requirements of explosion-proof electrical products.

[0024] Example 2: Based on Example 1, as follows Figure 2 As shown, the first detachable wire-passing encapsulated connecting joint assembly 12 includes an explosion-proof hollow bolt 14, and the rear end of the outer wall of the explosion-proof hollow bolt 14 is movably connected to the front end of the inner wall of the first explosion-proof housing 10, and the front end of the outer wall of the explosion-proof hollow bolt 14 movably passes through the rear end of the inner wall of the second explosion-proof housing 11.

[0025] Example 3: Based on Examples 1 and 2, as follows... Figure 3 As shown, the front end of the outer wall of the explosion-proof hollow bolt 14 is threaded with a fixing nut 15 at the front end of the inner wall of the second explosion-proof housing 11, and the back of the fixing nut 15 is in movable contact with the rear end of the inner wall of the second explosion-proof housing 11. A cable 16 is provided on the inner wall of the explosion-proof hollow bolt 14, and the inner wall of the explosion-proof hollow bolt 14 at the outer wall of the cable 16 is filled with explosion-proof sealant 17.

[0026] The working principle of this utility model is as follows: In use, the cable 16 is first passed through the explosion-proof hollow bolt 14. Then, explosion-proof sealant 17 is filled into the inner wall of the explosion-proof hollow bolt 14 at the outer wall of the cable 16. The explosion-proof hollow bolt 14 is then installed onto the front end of the inner wall of the first explosion-proof housing 10 and the second explosion-proof housing 11, respectively, with the front end of the outer wall of the explosion-proof hollow bolt 14 moving through the rear end of the inner wall of the second explosion-proof housing 11. Then, a fixing nut 15 is threaded onto the front side of the front end of the outer wall of the explosion-proof hollow bolt 14 at the rear end of the inner wall of the second explosion-proof housing 11 to fix the explosion-proof hollow bolt 14. This achieves a fixed connection between the first explosion-proof housing 10 and the second explosion-proof housing 11. When maintenance or replacement is required, simply cut the cable 16 and unscrew the fixing nut 15 to remove and replace the explosion-proof hollow bolt 14. There is no need to replace the entire first explosion-proof housing 10 and the second explosion-proof housing 11, thus reducing the overall maintenance cost.

[0027] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
