Detailed implementation manners

[0034] The present invention will be further described below in conjunction with the drawings and embodiments.

[0035] The present invention provides a storage and fixing device for a powder starter, as shown in Figure 1 , Figure 2 , which includes a fixing frame 1. The fixing frame 1 includes four vertically arranged support frames, and multiple layers of bottom plates 2 arranged from bottom to top between the four support frames. The support frames are L-shaped and are located at the four top corners of the bottom plate 2. In this embodiment, the bottom plate 2 of the fixing frame 1 has a three-layer structure arranged up and down, and the bottom plate 2 is made of Q235 material. The bottom plate 2 is provided with fixing screw holes with a diameter of φ11 for passing through bolts 5 to realize fixed connection with the shell. The bolt 5 uses an M10 bolt. The length of the bottom plate 2 is 1200 mm, the width is 700 mm, and the thickness is 10 mm; the height of the support frame is 1300 mm. Multiple shells are arranged on the bottom plate 2, and the shells include Type I shells 3 and Type II shells 4.

[0036] The shell includes an upper tile cover and a lower tile cover adapted to the upper tile cover. The upper tile cover and the lower tile cover are both made of stainless steel. According to different models of powder starters, the shells are divided into Type I shells 3 and Type II shells 4. The bottom plates 2 located at the top layer and the middle layer are used for fixed connection with Type I shells 3. There are two rows of Type I shells 3 distributed front and back on the bottom plate 2, and each row contains 5 Type I shells 3. The bottom plate 2 located at the middle layer is the same as the bottom plate 2 located at the top layer, and both are installed with 10 powder starters. As shown in Figure 3 , Figure 4As shown in the figure, it is the upper cover structure of the Type I shell holder 3. The upper cover includes a rear section 32 of the upper cover in the shape of a semi-cylindrical tube and a front section 31 of the upper cover. The inner diameter of the rear section 32 of the upper cover is greater than that of the front section 31 of the upper cover, and the length of the front section 31 of the upper cover is greater than that of the rear section 32 of the upper cover. One end of the front section 31 of the upper cover is connected to the rear section 32 of the upper cover, and the other end is provided with an arc-shaped groove, which is convenient for holding it during disassembly or installation of the upper cover. One end of the rear section 32 of the upper cover away from the front section 31 of the upper cover is provided with a semi-circular notch. Upper connecting pieces are respectively arranged on the two lower sides of the front section 31 of the upper cover. The upper connecting piece includes a connecting piece 33, and a connecting hole 34 with a diameter of φ11 is arranged at the center of the connecting piece 33, which is used to pass through the bolt 5 to realize the fixed connection with the lower cover.

[0037] As Figure 5 , Figure 6 shown in the figure, it is the lower cover structure of the Type I shell holder 3. The lower cover includes a rear section 38 of the lower cover and a front section 37 of the lower cover that are respectively adapted in size to the rear section 32 of the upper cover and the front section 31 of the upper cover. One end of the rear section 38 of the lower cover is connected to the front section 37 of the lower cover. The other end of the rear section 38 of the lower cover is provided with the same semi-circular notch as that on the rear section 32 of the upper cover. A fixing piece is arranged at the bottom of the front section 37 of the lower cover. The fixing piece includes a fixing support 35, and fixing holes 36 adapted to the fixing screw holes on the bottom plate 2 are arranged on both sides of the fixing support 35. The lower cover is fixed on the bottom plate 2 by passing the bolt 5 through the fixing hole 36 and the fixing screw hole. Lower connecting pieces identical to the upper connecting pieces are arranged on the two upper sides of the front section 37 of the lower cover. The lower connecting piece includes a connecting piece 33, and a connecting hole 34 is arranged at the center of the connecting piece 33. The lower cover and the upper cover are fixedly connected by passing the bolt 5 through the lower connecting piece and the connecting hole 34 on the upper connecting piece. A cylindrical cavity is formed between the upper cover and the lower cover, and the diameter of the front section of the cavity is smaller than that of the rear section, which is used to place the powder initiator. The rear end of the powder initiator is a flange surface, and it is fixed by forming a circular notch through the semi-circular notches of the rear sections of the upper cover and the lower cover. On the inner walls of the upper cover and the lower cover of the Type I shell holder 3, protective pads are provided. In this embodiment, the protective pad is made of protective rubber with a thickness of 2 mm. By laying the protective rubber between the upper and lower covers, the surface of the powder initiator can be protected, effectively avoiding surface damage.

[0038] The bottom plate 2 located at the bottom layer of the fixing frame is used to fixedly connect the Type II shell holder 4. There are two rows of Type II shell holders 4 distributed front and back, and each row contains 7 Type II shell holders 4. As Figure 7 shown in the figure, it is the upper cover structure of the Type II shell holder 4. As Figure 8As shown, it is the lower tile cover structure of the Type II shell holder 4. The upper tile cover structure and the lower tile cover structure of the Type II shell holder 4 are the same as those of the upper tile cover structure and the lower tile cover structure of the Type I shell holder 3. The difference is that the length of the Type II shell holder 4 is less than that of the Type I shell holder 3, and the diameter of the cavity of the Type II shell holder 4 is less than the diameter of the cavity of the Type I shell holder 3. Inside the upper tile cover and the lower tile cover of the Type II shell holder 4, protective rubber is also provided, and the thickness of the rubber is 2 mm, which is used to protect the surface of the powder initiator.

[0039] Installation process: Taking the disassembly and assembly of the Type I shell holder 3 as an example, first align the fixing hole 36 on the fixing support 35 with the fixing screw hole on the bottom plate 2, and use the bolts 5 to pass through the fixing hole 36 and the fixing screw hole on the bottom plate 2 respectively to complete the fixation of the lower tile cover. Place the powder initiator in the lower tile cover, then align the upper tile cover with the lower tile cover, and use the bolts 5 to pass through the connection holes 34 on both sides of the upper tile cover and the lower tile cover to fix the upper tile cover and the lower tile cover. Thus, the stable and reliable storage of the powder initiator is completed. When in use, first remove the bolts 5 in the connection holes 34 on both sides of the upper tile cover and the lower tile cover of the Type I shell holder 3 to cancel the displacement limit in the vertical direction of the powder initiator, and then remove the bolts 5 in the fixing screw hole of the bottom plate 2 and the fixing hole 36 of the lower tile cover to cancel the limit on the lower tile cover, and the convenient disassembly and assembly of the powder initiator can be realized.
