[0029] To make the inventive objectives, features, and advantages of this application more apparent and understandable, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.
[0030] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.
[0031] This application discloses a cast-in-place through-wall insulation component, such as... Figure 1 As shown, the system includes a through-wall section 1 and two sealed boxes 2. The through-wall section 1 is located between the two sealed boxes 2 and is integrally formed by casting. The through-wall section 1 is made of volcanic rock mineral material, which can improve the system's fire resistance and effectively slow the spread of fire in the event of a fire, protecting electrical equipment and personnel safety. A connecting copper busbar 11 is installed inside the through-wall section 1, and a connecting copper busbar 21 is installed inside the sealed boxes 2. The connecting copper busbar 11 and the connecting copper busbar 21 are connected. The through-wall section 1 protects the connecting copper busbar 11, and the sealed boxes 2 protect the connecting copper busbar 21. The through-wall section 1 effectively prevents electrical faults and avoids short circuits or current leakage caused by electrical contact between the wall and the connecting copper busbar 11 and the connecting copper busbar 21. Furthermore, the overall structure of the through-wall section 1 is robust, reducing the possibility of damage from external environmental influences.
[0032] like Figure 1 and 2 As shown, a transition section 3 is provided between the through-wall portion 1 and the sealing box 2. The transition section 3 is integrally formed by casting and is fixedly connected to the through-wall portion 1. The sealing box 2 and the transition section 3 are fitted together. Both ends of the connecting copper busbar 11 are located inside the transition section 3, and one end of the connecting copper busbar 21 is located inside the sealing box 2, while the other end is located inside the transition section 3. The transition section 3 also provides a certain mechanical strength to prevent physical collisions from the outside of the wall from damaging the connecting copper busbar 11 or the connecting copper busbar 21, and increases the installation distance between the connecting copper busbar 11 and the connecting copper busbar 21 and the surrounding wall.
[0033] like Figure 1 As shown, the adapter 3 is equipped with a connecting bolt 31, which is threadedly connected to both the connecting copper busbar 11 and the connecting copper busbar 21. When the connecting copper busbar 11 and the connecting copper busbar 21 are in contact, the operator can screw in the connecting bolt 31. The connecting bolt 31 can limit the movement of the connecting copper busbar 11 and the connecting copper busbar 21, and also facilitates electrical transmission between them. A cover 32 is fixedly connected to the adapter 3. The cover 32 covers the end of the connecting bolt 31 that extends out of the adapter 3, protecting the end of the connecting bolt 31 and reducing the possibility of damage to the connecting bolt 31, thereby reducing the possibility of damage to the connecting copper busbar 11 and the connecting copper busbar 21.
[0034] like Figure 1 and 2As shown, a reinforcing block 12 is provided on the connecting copper busbar 11. The reinforcing block 12 is integrally formed by casting. The connecting copper busbar 11 passes through the reinforcing block 12, which is located inside the wall penetration part 1. The reinforcing block 12 can further protect the connecting copper busbar 11, improve its stability, and reduce the possibility of damage. An insulating sleeve 22 is fixedly connected to the inside of the sealed box 2. The insulating sleeve 22 is fitted onto the end of the connecting copper busbar 21 located inside the sealed box 2. The insulating sleeve 22 can limit the position of the connecting copper busbar 21, improving its positional accuracy. The insulating sleeve 22 can also protect the connecting copper busbar 21, improving its insulation and facilitating electrical transmission.
[0035] like Figure 1 and 3 As shown, a pressure-resistant plate 4 is fixedly connected to the side of the adapter 3 facing the wall-penetrating part 1. Several serrated grooves 41 are formed on the side of the pressure-resistant plate 4 away from the adapter 3. Several rubber strips 42 are adhered to the pressure-resistant plate 4, located within the serrated grooves 41, abutting against the groove walls, and fitting snugly against the wall. When subjected to external forces, the rubber strips 42 buffer the forces acting on the pressure-resistant plate 4, reducing the force on the pressure-resistant plate 4. The serrated grooves 41 improve the structural strength of the pressure-resistant plate 4, reducing the possibility of damage. The pressure-resistant plate 4 protects the adapter 3, increasing its pressure resistance and further reducing the possibility of damage. This facilitates the protection of the adapter 3 for the connecting copper busbar 11 and the connecting copper busbar 21.
[0036] The implementation principle of a cast-in-place through-wall insulation component in this application is as follows:
[0037] The through-wall part 1 can protect the connecting copper busbar 11, and the sealing box 2 can protect the connecting copper busbar 21. The through-wall part 1 can effectively prevent electrical faults and avoid short circuits or current leakage caused by electrical contact between the wall and the connecting copper busbar 11 and the connecting copper busbar 21. The adapter part 3 can also provide a certain mechanical strength to prevent physical collisions outside the wall from damaging the connecting copper busbar 11 or the connecting copper busbar 21, and increase the installation distance between the connecting copper busbar 11 and the connecting copper busbar 21 and the surrounding wall.
[0038] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
