Detailed Implementation
[0025] 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. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.
[0026] like Figures 1-6As shown, the proposed quick-assembly, non-disassembly assembly cannon-shaped pyrotechnic device includes a steel frame 1, quick-connecting corner pieces 2, and partition plates 3. The steel frame 1 is a hollow cavity with an open top. The quick-connecting corner pieces 2 are located at the four corners of the upper end of the steel frame 1. Several partition plates 3 are fixed inside the steel frame 1, dividing the steel frame 1 into several firing slots 4. Several cannons 5 are located in each firing slot 4. Several flip-top covers 6 are located at the open end of the steel frame 1, and the flip-top covers 6 are located in the firing slots 4. Above, several flip-up cover plates 6 are axially connected at one end to the steel frame 1. A connecting rod 16 is provided on one side of each flip-up cover plate 6. The connecting rod 16 is axially connected to one end of the flip-up cover plate 6 away from the hinge point with the steel frame 1. The two sides of the flip-up cover plate 6 are respectively connected to the steel frame 1 and the connecting rod 16. The quick-connecting corner piece 2 is set as a hollow cavity. The top wall of the quick-connecting corner piece 2 is provided with a splicing hole 7, which penetrates the top wall of the quick-connecting corner piece 2. The side wall of the quick-connecting corner piece 2 is provided with a side hole 8, which penetrates the side wall of the quick-connecting corner piece 2.
[0027] like Figure 1 , Figure 5 and Figure 6 As shown, when multiple sets of steel frames 1 are combined, quick-connecting components 9 are provided above adjacent quick-connecting corner pieces 2. The quick-connecting components 9 include double-ended bolts 10, nuts 11, and clamping rods 12. The double-ended bolts 10 are located above the quick-connecting corner pieces 2. There are two nuts 11, which are sleeved on the outside of the double-ended bolts 10. The clamping rods 12 are fixed to one side of the nuts 11 and are L-shaped. One end of the clamping rods 12 passes through the splicing hole 7 and is located inside the quick-connecting corner pieces 2. A partition block 14 is provided in the middle of the double-ended bolts 10, and the partition block 14 is located between the two nuts 11.
[0028] like Figures 3-5 As shown, a signal cable groove 17 is provided on one side of the firing trough 4. The signal cable groove 17 is located inside the steel frame 1 and the partition plate 3. Several signal transmission lines 13 are provided inside the signal cable groove 17. One end of the signal transmission line 13 is provided with a quick connector 19. The quick connector 19 is connected to the ignition head inside the barrel 5. The signal transmission line 13 is connected to the barrel 5. The signal transmission line 13 is located inside the partition plate 14 or the steel frame 1 on one side of the firing trough 4. The end of the signal transmission line 17 away from the barrel 5 is provided with a servo connector 18. The servo connector 18 is located on the side wall of the steel frame 1.
[0029] The ignition trough 4 is equipped with an explosion-proof material 15, which is located between the barrels 5. The barrels 5 are made of steel.
[0030] In practical use, multiple cannon tube 5 fireworks display devices are combined according to the drawings. A crane is used to lift the steel frame 1 to the designated position. The hooks are hooked onto the quick-connect corner pieces 2 at the four corners of the steel frame 1, thereby stabilizing the transport of the cannon tube 5 fireworks display devices. Unlike the traditional manual handling of individual devices, this method saves time and effort. The use of its own weight and the large contact area between the combined body and the ground greatly increases its stability.
[0031] After the fireworks display equipment (cannon barrel 5) is placed, the adjacent steel frames 1 are fixed together using the quick-connect assembly 9. The two clamping rods 12 are inserted into the two quick-connecting corner pieces 2 respectively. Then, the double-ended bolt 10 is rotated, causing the double-ended bolt 10 to drive the nut 11 to move towards the partition block 14, so that the clamping rod 12 is pressed against the side wall of the splicing hole 7 and one end of the clamping rod 12 is stuck in the quick-connecting corner piece 2, thereby clamping the two adjacent quick-connecting corner pieces 2 and fixing the steel frame 1. This facilitates the quick assembly of multiple steel frames 1 together, shortens the construction period, and reduces labor costs. After multiple fireworks display equipment are assembled, the quick-connect connector 19 at one end of the signal transmission line 13 is connected to the ignition head, and the signal transmission lines 13 corresponding to each row of cannon barrels are placed in the signal cable tray 17. The end of all signal transmission lines 13 away from the quick-connect connector 19 is connected to the servo connector 18, which facilitates the connection to external control settings.
[0032] Before the fireworks are set off, the flip cover 6 is placed over the opening of the cannon barrel 5 to prevent foreign objects and rainwater from entering. Before the fireworks are set off, the flip cover 6 is opened. Under the action of the connecting rod 16, multiple flip covers 6 are opened together, so that the flip cover 6 can be flipped to cover the signal cable groove 17 without covering the position of the other row of cannon barrels 5. The signal transmission line 13 is hidden in the signal cable groove 17 to avoid the low explosion of the shell or accidental burning that could damage the signal line, thus improving the safety factor.
