Description

Technical Field

[0001] This utility model relates to the field of fireworks production technology, and in particular to a safety fuse combustion performance testing device. Background Technology

[0002] Firework safety fuses are key components used to ignite fireworks and control their burning speed. Since fireworks fuses contain a certain amount of gunpowder, strict safety monitoring is essential to ensure their safety and the personal safety of those setting them off. Traditional methods for detecting the burning of fireworks fuses require manual calculation, which introduces errors. The smoke produced during fuse combustion can also obstruct the inspector's view, affecting the accuracy of the test. Furthermore, these methods can only detect the overall burning speed of the fuse; if segmented testing is required, multiple repeated tests are necessary, which is time-consuming and labor-intensive.

[0019] The present invention will be explained in detail through the following embodiments. The purpose of disclosing the present invention is to protect all technical improvements within the scope of the present invention.

[0020] Combined with appendix Figures 1-5 A safety fuse combustion performance testing device includes a workbench, support rods 7, a smoke guide device, slide rails 11, support devices, a temperature sensor 17, and a signal transmitter 6. The firework fuse burns above the workbench. The workbench consists of a shell 1, columns 2, and a support plate 3. The shell 1 has an opening at the top, and columns 2 are distributed on the lower end face of the shell 1. The support plate 3 is located at the opening of the shell 1, and support rods 7 are distributed above the support plate 3. The smoke guide device is installed on the support rods 7 to exhaust the smoke generated during the fuse combustion from above the workbench. Two slide rails 11 are provided on the inner wall of the shell 1, and support devices are distributed on the two slide rails 11. The fuse is installed on each support device, and a temperature sensor 17 is installed on the support device. A signal transmitter 6 is located at one end of the shell 1. The temperature sensor 17 is connected to the signal transmitter 6, and the signal transmitter 6 is connected to the background monitoring terminal.

[0021] The smoke guiding device includes a flow guide hood 8, an exhaust pipe 9, and a fan 10. The flow guide hood 8 has an inverted funnel-shaped structure. An exhaust pipe 9 is provided above the flow guide hood 8 and is connected to it. A fan 10 is provided inside the exhaust pipe 9. The fan 10 draws air outward, and the airflow draws the smoke generated when the fuse is burning upward to avoid the smoke affecting the experimental personnel's observation.

[0022] The housing 1 is provided with a through groove running through both sides, and the support plate 3 is located above the through groove. The support plate 3 has perforations 4 distributed on it. The housing 1 is provided with a support plate 16 arranged parallel to the support plate 3. The residue after the lead wire burns can fall below through the perforations 4.

[0023] A tray 5 is provided above the support plate 16. The tray 5 is located directly below the bearing plate 3. The tray 5 contains water. The residue after the lead wire burns is placed in the water in the tray 5 to avoid fire hazards caused by the residue scattering.

[0024] The slide rail 11 is arranged horizontally, and the slide rails 11 on both sides of the housing 1 are symmetrically arranged. Each slide rail 11 is provided with a slidingly connected slider 13, and each slider 13 is provided with a support device. The distance between each slider 13 can be increased or decreased according to different test contents.

[0025] At least one connecting plate 12 is provided above the bearing plate 3. The lower end face of the connecting plate 12 is provided with a locking block 18 with a through hole 4. The upper end face of the bearing plate 3 is provided with a support device in an equidistant array.

[0026] The support device includes a fixed rod 14 and a collar 15. One end of the fixed rod 14 is provided with a collar 15. The lead wire passes through each collar 15 provided on the slide rail 11 or the connecting plate 12. Each collar 15 is provided with a temperature sensor 17 on its inner wall. During the burning process of the lead wire, when it approaches the temperature sensor 17, the temperature sensor 17 records the high temperature generated during the burning of the lead wire and transmits the collected data signal to the signal transmitter 6, which then transmits the data back to the back-end terminal.

[0027] The safety lead wire combustion performance testing device described in this embodiment first adjusts the spacing between the sliders 13 according to experimental requirements. Then, the lead wire is passed through each collar 15, and one end of the lead wire is ignited. The lead wire begins to burn. When the burning part of the lead wire approaches the temperature sensor 17, the temperature sensor 17 records the high temperature generated during the burning of the lead wire and transmits the collected data signal to the signal transmitter 6. The signal transmitter 6 transmits the data back to the back-end terminal. The burning speed of the lead wire can be calculated based on the detection time and the return speed of each temperature sensor 17, as well as the time change of the high temperature measured by two adjacent temperature sensors 17, to observe the uniformity of the lead wire. After the lead wire has finished burning, the fan 10 is turned on to draw air outward. The airflow draws the smoke generated during the burning of the lead wire upward to avoid the smoke affecting the experimental personnel's observation. The residue after the lead wire has burned can fall into the water in the tray 5 below through the perforation 4 to avoid the fire hazard caused by the residue scattering.
