Description

Technical Field

[0001] This utility model relates to the field of fire-fighting equipment, and in particular to an automatic fire extinguishing device for fireworks and firecracker production. Background Technology

[0002] During fireworks production, pyrotechnic agents need to be granulated to achieve better ignition effects. Granulation of pyrotechnic agents typically uses a granulator. During granulation, the pyrotechnic agent is poured into the rotating drum of the granulator and a binder is sprayed on. The rotating drum drives the pyrotechnic agent and binder droplets to rotate, gradually forming granules. During this process, the heat and static electricity generated by prolonged friction can easily cause the pyrotechnic agent to ignite and produce a fire.

[0003] However, in real factories, fire extinguishing devices are often handheld fire extinguishers or ceiling-mounted spray fire extinguishers. Handheld fire extinguishers are often scattered throughout the factory, requiring workers to move them before extinguishing the fire. Ceiling-mounted spray fire extinguishers require a certain response time before they can spray and extinguish the fire. Therefore, traditional fire extinguishing devices are not convenient for responding quickly and extinguishing the fire immediately when a fire occurs, resulting in poor fire extinguishing efficiency. Utility Model Content

[0004] In order to overcome the shortcomings of traditional fire extinguishing devices, which are inconvenient to respond quickly and extinguish the fire immediately when a fire occurs, resulting in poor fire extinguishing efficiency, this utility model provides an automatic fire extinguishing device for fireworks and firecracker production that can respond quickly and extinguish the fire immediately when a fire occurs, and has higher fire extinguishing efficiency.

[0005] The technical solution of this utility model is: an automatic fire extinguishing device for fireworks and firecrackers production, including a mounting frame;

[0006] Two guide brackets fixed to the mounting frame;

[0007] An electric push rod fixed to the upper part of the mounting bracket;

[0008] A locking block fixed to the telescopic rod of the electric push rod;

[0009] A water storage tank that slides between two guide frames;

[0010] Triggering mechanism is set on the mounting bracket and electric push rod;

[0011] The opening and closing mechanism is installed on the water storage tank.

[0012] Furthermore, the triggering mechanism includes a cylinder fixed to the mounting bracket, a small hole at the bottom of the cylinder, a lead wire conduit fixed between the mounting bracket and the bottom of the cylinder, a quick lead wire inserted into the lead wire conduit, the upper end of the quick lead wire located inside the cylinder, a piston slidably connected to the cylinder, two guide seats fixed to the mounting bracket, a transmission frame slidably connected between the two guide seats, one side of the transmission frame being fixed to the top of the piston, a first switch fixed to the mounting bracket, and a second switch fixed to the mounting bracket. Both the first and second switches are electrically connected to an electric push rod.

[0013] Furthermore, the opening and closing mechanism includes a sliding frame slidably connected to the water storage tank, two return springs disposed between the water storage tank and the sliding frame, a sealing sheet fixed to the sliding frame, the sealing sheet covering the drain outlet of the water storage tank, and a contact frame fixed to the sliding frame.

[0014] Furthermore, the sealing sheet is made of wear-resistant silicone.

[0015] Furthermore, the lower part of the inner wall of the water storage tank is provided with a slope.

[0016] The beneficial effects of this utility model are: 1. When a fire occurs, the flame ignites the quick fuse, which ignites the gunpowder in the cylinder. The explosive combustion of the gunpowder pushes the piston and transmission frame upward. The transmission frame presses switch one, and the electric push rod retracts, causing the locking block to disengage from the water tank. The water tank drives the sliding frame, return spring, sealing plate, and contact frame to move downward. The guide frame blocks the contact frame, and the sliding frame and sealing plate no longer block the drain of the water tank. The water in the water tank rushes into the rotating cylinder to extinguish the fire. This allows for a quick response and immediate extinguishing of the fire source when a fire occurs, resulting in higher fire extinguishing efficiency. Attached Figure Description

Detailed Implementation

[0024] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0025] Example 1: An automatic fire extinguishing device for fireworks and firecracker production, such as... Figures 1-6 As shown, it includes, mounting bracket 1;

[0026] Two guide frames 2 are fixed to the mounting frame 1, and the two guide frames 2 are arranged symmetrically.

[0027] An electric push rod 3 is fixed to the upper part of the mounting bracket 1, and the electric push rod 3 is set at an angle.

[0028] The locking block 4 is fixed to the telescopic rod of the electric push rod 3;

[0029] A water storage tank 5 is slidably connected between two guide frames 2. The water storage tank 5 is inclined. The upper and lower parts of the water storage tank 5 have water inlet and water outlet respectively. The water storage tank 5 has a slot, and the slot 4 is located in the slot of the water storage tank 5.

[0030] The triggering mechanism, which is installed on the mounting bracket 1 and the electric push rod 3, is used to monitor and respond to fire situations.

[0031] An opening and closing mechanism is provided on the water storage tank 5, which is used to control the outflow of water from the water storage tank 5.

[0032] The triggering mechanism includes a cylinder 6 fixed to the mounting frame 1, the top of the cylinder 6 being open and the bottom of the cylinder 6 having a small hole; a lead wire conduit 7 fixed between the mounting frame 1 and the bottom of the cylinder 6, one end of the lead wire conduit 7 extending into the rotating drum of the granulator; a quick lead wire 8 inserted into the lead wire conduit 7, the upper end of the quick lead wire 8 located inside the cylinder 6; a piston 9 slidably connected inside the cylinder 6, the piston 9 being tightly fitted to the inner wall of the cylinder 6; two guide seats 10 fixed to the mounting frame 1; a transmission frame 11 slidably connected between the two guide seats 10, one side of the transmission frame 11 being fixed to the top of the piston 9; a switch 12 fixed to the mounting frame 1; and a switch 23 fixed to the mounting frame 1. Both switches 12 and 23 are electrically connected to the electric push rod 3.

[0033] The opening and closing mechanism includes a sliding frame 14 slidably connected to the water storage tank 5, two return springs 15 disposed between the water storage tank 5 and the sliding frame 14, a sealing plate 16 fixed to the sliding frame 14, the sealing plate 16 covering the drain outlet of the water storage tank 5, a contact frame 17 welded to the sliding frame 14, and a guide frame 2 blocking the sliding frame 14 and the sealing plate 16 through the contact frame 17, thereby exposing the drain outlet of the water storage tank 5.

[0034] Initially, mounting bracket 1 is installed on the upper part of the pyrotechnic agent granulator. Switch 12 is the retraction button for electric push rod 3, and switch 2 13 is the extension button for electric push rod 3. Clamp 4 holds water tank 5, which is filled with water, with the liquid level below the inlet. Sealing plate 16 covers the drain of water tank 5, thus limiting the water level. Explosive is filled between the bottom of piston 9 and cylinder 6. During granulation, one end of lead wire guide 7 and quick lead wire 8 is always inside the rotating drum of the granulator. If an accidental fire occurs inside the rotating drum, due to the shape and structure of the rotating drum, the flame may escape from... The opening of the rotating cylinder bursts open, igniting the quick-acting fuse 8. The quick-acting fuse 8 immediately ignites the gunpowder inside the cylinder 6. The thrust generated by the explosive combustion of the gunpowder pushes the piston 9 upward. The upward movement of the piston 9 drives the transmission frame 11 upward. The transmission frame 11 moves upward and contacts the switch 12, pressing the switch 12. The electric push rod 3 retracts, causing the locking block 4 to disengage from the water tank 5. The locking block 4 is no longer in the water tank 5. Under the action of gravity, the water tank 5 slides along the guide frame 2 to the position blocking the opening of the rotating cylinder. The downward movement of the water tank 5 drives the sliding frame 14 and the return spring 15 downward. The downward movement of the sliding frame 14 drives the sealing plate... 16 and contact frame 17 move downwards, guide frame 2 blocks contact frame 17, return spring 15 is compressed, sliding frame 14 and sealing plate 16 no longer block the drain of water tank 5, and under the action of gravity, water in water tank 5 will rush into the rotating drum to extinguish the fire. Through the above operation, it is convenient to respond quickly and extinguish the fire source immediately when a fire occurs, and the fire extinguishing efficiency is higher. After the fire is extinguished, the operator holds the transmission frame 11 to pull piston 9 out of cylinder 6, re-inserts a quick lead wire 8 through the small hole at the bottom of cylinder 6, and makes the lower end of quick lead wire 8 extend into the rotating drum of the granulator, leaving a certain length of the upper end in the cylinder. Inside cylinder 6, after the quick-connect wire 8 is inserted, the worker fills the bottom of the inner wall of cylinder 6 with gunpowder again and pushes piston 9 back into cylinder 6. Then, the worker pushes water tank 5 upward to the initial position. During the upward movement of water tank 5, the return spring 15 will rebound and drive the sliding bracket 14 and sealing plate 16 to cover the drain port of water tank 5 again. After water tank 5 returns to the initial position, the worker presses switch 13. The electric push rod 3 drives the locking block 4 back into the slot of water tank 5. The locking block 4 locks the water tank 5 again. Finally, the worker adds an appropriate amount of water through the inlet of water tank 5 to facilitate the next operation.

[0035] Example 2: Based on Example 1, such as Figure 1 , Figure 2 and Figure 6 As shown, the sealing sheet 16 is made of wear-resistant silicone material, which can increase the wear resistance and airtightness of the sealing sheet 16.

[0036] The lower part of the inner wall of the water storage tank 5 is provided with a slope, which is used to guide the water.

[0037] The sealing sheet 16 is made of wear-resistant silicone material, which can extend its service life and increase the airtightness between the sealing sheet 16 and the water storage tank 5.

[0038] The sloping surface at the bottom of the inner wall of the water storage tank 5 allows water to flow more smoothly into the rotating drum of the granulator and reduces the amount of water that may remain at the bottom of the water storage tank 5.

[0039] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
