Description

Technical Field

[0001] The present application relates to the field of fireworks production, and more specifically, to a lead safety protection device for fireworks production. Background Art

[0002] The lead has the characteristics of being flammable and transmitting fire, which will inevitably lead to the spread of fire, causing fire, property losses and even casualties. Therefore, some lead safety protection devices are required during the production of fireworks. However, due to the relatively fast burning speed of the lead, when a fire alarm occurs, the reaction time to stop its spread is short, and most of the current protection devices cannot respond in time.

[0003] The patent document with the publication number CN219869321U discloses a lead safety protection device for fireworks production, including: a bottom plate, a truncation box is arranged at the middle position of the upper surface of the bottom plate, a guillotine knife is arranged inside the truncation box, a connecting rod is connected to the upper end of the guillotine knife, the connecting rod, a support rod is fixedly installed on the left side of the upper end of the truncation box, a detection box is arranged on the left side of the upper surface of the bottom plate, and a limiting ball is arranged inside the detection box; by providing a truncation box, when the lead appears to be ignited, the gunpowder inside the limiting ball will be ignited through the ignition wire, thereby exploding the limiting ball, thus releasing the limitation of the connecting wire on the limiting ball, and then releasing the limitation on the connecting rod through the connecting wire, and then braking the guillotine knife through a support spring, thereby driving the guillotine knife to quickly fall, and falling into the slot opened at the lower end of the truncation box, thereby cutting off the lead to prevent fire. Although the above application document releases the limitation on the connecting rod through the connecting wire and then brakes the guillotine knife through a support spring, thereby driving the guillotine knife to quickly fall, and thus can carry out fire extinguishing operations, but if the lead burns too fast and is not cut off in time, it will still trigger a safety accident. Summary of the Utility Model

[0004] Aiming at the deficiencies of the prior art, the present utility model provides a lead safety protection device for fireworks production, which solves the problems raised in the above background art. To achieve the above objectives, the present utility model is realized through the following technical solutions: A lead safety protection device for fireworks production, including a base, a protection device is arranged on the base, the protection device includes a fixed block, the fixed block is fixedly connected to the top of the base, a wire winding column is fixedly connected to the top of the fixed block, a PE fishing line is fixedly connected to the top of the wire winding column, a sleeve is fixedly connected to the top of the base, a fixed plate is fixedly connected to the front surface of the inner wall of the sleeve, a cutting knife is fixedly connected to the bottom of the PE fishing line, a spring is fixedly connected to the top of the cutting knife, a vertical block is fixedly connected to the top of the base, a first rotating rod is rotatably connected to the left side of the vertical block through a bearing, a circular gear is fixedly sleeved on the outer wall of the first rotating rod, a notch is opened on the right side of the sleeve, a rack is fixedly connected to the right side of the cutting knife, and a dry powder cylinder is fixedly connected to the right side of the first rotating rod.

[0005] Preferably, the circular gear meshes with the rack.

[0006] Preferably, threading holes are formed on both sides of the sleeve.

[0007] Preferably, a warning device is provided on the base. The warning device includes a first bevel gear fixedly sleeved on the outer wall of a first rotating rod. A transverse block is fixedly connected to the back of the sleeve. The top of the transverse block is rotatably connected to a second rotating rod through a bearing, and a warning light is fixedly connected to the top of the second rotating rod.

[0008] Preferably, the second rotating rod extends downward through the transverse block movably, and a second bevel gear is fixedly connected to the bottom of the second rotating rod.

[0009] Preferably, the first bevel gear and the second bevel gear mesh with each other.

[0010] The advantages of the present application are as follows:

[0011] First, by providing a protection device in the present application, the lead wire passes through the threading hole. If the lead wire catches fire, the PE fishing line on the winding column will be burned off. After the PE fishing line is burned off, the spring drives the cutter to drop to cut the lead wire. The cutter drives the rack to descend, the rack drives the circular gear to rotate counterclockwise, the circular gear drives the first rotating rod to rotate counterclockwise, and the first rotating rod drives the dry powder cylinder to pour on the surface of the lead wire. The cutting action can effectively prevent the fire from spreading further and avoid the problem of the lead wire burning too fast. Pouring the content of the dry powder cylinder on the surface of the lead wire, this mechanism realizes automatic fire extinguishing of the burning lead wire, further enhancing safety, and thus solves the problem that the lead wire burns too fast in the background art and still triggers a safety accident if not cut off in time.

[0012] Second, by providing a warning device in the present application, the first rotating rod drives the first bevel gear to rotate, the first bevel gear drives the second bevel gear to rotate, the second bevel gear drives the second rotating rod to rotate, and the second rotating rod drives the warning light to rotate. By emitting a warning signal, it ensures that workers can obtain a warning in time when the equipment is running, reduces the probability of accidents, improves the safety of the work site, and protects workers from potential equipment operation risks.
