Description

Technical Field

[0001] This utility model relates to the field of civilian explosives transportation technology, specifically to an explosion-proof device for the transportation of civilian explosives. Background Technology

[0002] When exposed to heat, explosive materials undergo violent chemical changes, releasing large amounts of heat and gas in a very short time, generating tremendous impact force. Among explosive materials, civilian explosives are those used in civilian applications, commonly used to manufacture pyrotechnic agents, civilian signal flares, and explosive devices such as firecrackers or small gunpowder products permitted for civilian use.

[0003] Currently, Chinese Patent CN219635799U discloses an explosion-proof device for transporting civilian explosives, which can effectively fix civilian explosives and prevent them from exploding due to excessive vibration during transportation. This application includes: a first guide rail installed on one side of the base plate, and a second guide rail installed on the other side; a first positioning component and a second positioning component movably installed on the first and second guide rails; a clamping and fixing component connected to the first and second positioning components; a placement area formed between the first and second positioning components; and a shock-absorbing buffer component disposed in the placement area. The clamping and fixing component, in conjunction with the shock-absorbing buffer component, is used to fix the storage box in the placement area, and the shock-absorbing buffer component is used to reduce the vibration force on the storage box. While this device solves the above-mentioned problems, it also presents the following issues: the rectangular area formed by the first and second positioning components is relatively fixed, resulting in poor adaptability to storage boxes of different shapes and sizes; it lacks fire and explosion protection functions; and it does not include a fire extinguishing agent spraying mechanism, thus reducing transportation safety. Utility Model Content

[0004] The purpose of this utility model is to provide an explosion-proof device for transporting civilian explosives, so as to overcome the shortcomings of the prior art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An explosion-proof device for transporting civilian explosives includes an explosion-proof transport box, a shock-absorbing support device fixedly installed on the bottom surface of the explosion-proof transport box, a fixing device installed inside the explosion-proof transport box for placing civilian explosives, an explosion-proof cover installed on the top surface of the explosion-proof transport box, and an extinguishing device fixedly installed on the top surface of the explosion-proof cover; the top surface of the explosion-proof transport box is provided with connecting holes at the four corners, and the bottom surface of the explosion-proof cover is fixedly provided with connecting rods that can be riveted to the connecting holes at the four corners.

[0007] Furthermore, the shock-absorbing support device includes a seismic base plate, a seismic groove fixedly installed on the top surface of the seismic base plate, a guide rod fixedly installed on the inner wall of the seismic groove, a seismic slide seat sleeved on the guide rod, and a seismic movable rod fixedly connected to the top surface of the seismic slide seat; a spiral spring is also provided on one side surface of the seismic slide seat; seismic fixing seats are fixedly installed at the four corners of the top surface of the seismic base plate, a damping spring is fixedly installed inside the seismic fixing seat, and a seismic support rod is also provided at the top of the damping spring.

[0008] Furthermore, the number of the anti-seismic chute, guide rod, anti-seismic slide, anti-seismic movable rod, spiral spring, anti-seismic fixed seat, damping spring, and anti-seismic support rod are all four, and they are distributed in a mirror symmetrical manner. The anti-seismic movable rod is fixedly connected to the anti-seismic support rod and the bottom surface of the explosion-proof transport box, and the anti-seismic support rod passes through the anti-seismic fixed seat.

[0009] Furthermore, the fixing device includes a fixing plate, a fixing screw fixedly disposed on one side surface of the fixing plate, a fixing knob fixedly disposed on one side surface of the fixing screw, limiting seats fixedly disposed on the left and right sides of the fixing plate, and a limiting slide rod disposed inside the limiting seats.

[0010] Furthermore, the limiting slide bar is fixedly connected to the inner wall of the explosion-proof transport box, a shaft seat is provided at the connection between the fixing plate and the fixing screw, the fixing screw passes through the explosion-proof transport box, and the connection between the explosion-proof transport box and the fixing screw is provided with threads.

[0011] Furthermore, the extinguishing device includes a cover, a plurality of storage tanks disposed inside the cover, a supply pipe fixedly disposed on the bottom surface of the storage tanks, a pressure pump fixedly disposed on the bottom surface of the supply pipe, a diversion hose disposed on one side surface of the pressure pump with one axial end disposed thereon, and a nozzle fixedly disposed on the other axial end of the diversion hose. A temperature sensor is disposed at the bottom of the pressure pump.

[0012] As can be seen from the above technical solutions, this utility model has the following beneficial effects:

[0013] In this invention, the operator rotates a fixing knob, causing the fixing screw to rotate and move axially, thereby moving the fixing plate. Under the precise control of the limiting seat and the limiting slide rod, the fixing plate can tightly fit the packaging of explosive materials, achieving a secure fixation. This effectively avoids the dangers of explosions caused by shaking or collisions during transportation, laying a solid foundation for transportation safety. The position of the fixing plate can be flexibly adjusted according to different sizes of explosive material packaging, exhibiting good versatility and adaptability.

[0014] During transportation, the shock-absorbing support device plays a crucial role. When the vehicle vibrates, the explosion-proof transport box transmits the vibration to the anti-vibration movable rod and the anti-vibration support rod. The anti-vibration movable rod drives the anti-vibration slide block to slide on the guide rod, causing the spiral spring to undergo elastic deformation and absorb some of the vibration energy. At the same time, the anti-vibration support rod applies pressure to the damping spring, causing it to compress or extend, further absorbing and buffering the vibration. Through the coordinated work of the spiral spring and the damping spring, the amplitude of vibration transmitted to the explosion-proof transport box is greatly reduced, significantly lowering the risk of explosion of civilian explosives due to vibration and ensuring the stability of the transportation process.

[0015] When the temperature inside the container rises abnormally for any reason and reaches a preset threshold, the temperature sensor quickly transmits a signal to the pressure pump. The pressure pump immediately starts, delivering the extinguishing medium from the storage tank to each nozzle through the supply pipe and distribution hose. The nozzles then spray the extinguishing medium into the container. This effectively suppresses the combustion reaction, prevents the spread of fire and the occurrence of explosions, and comprehensively ensures the safety of transporting civilian explosives.

Connecting holes 6 are provided at the four corners of the top surface of the explosion-proof transport box 1, and connecting rods 7, capable of being riveted to the connecting holes, are fixedly installed at the four corners of the bottom surface of the explosion-proof cover 4.

[0023] like Figure 2 As shown, the shock-absorbing support device 2 of this preferred embodiment includes a seismic base plate 201, a seismic groove 202 fixedly disposed on the top surface of the seismic base plate 201, a guide rod 203 fixedly disposed on the inner wall of the seismic groove 202, a seismic slide seat 204 sleeved on the guide rod 203, and a seismic movable rod 205 fixedly connected to the top surface of the seismic slide seat 204; a spiral spring 206 is also disposed on one side surface of the seismic slide seat 204; a seismic fixing seat 207 is fixedly disposed at the four corners of the top surface of the seismic base plate 201, a damping spring 208 is fixedly disposed inside the seismic fixing seat 207, and a seismic support rod 209 is also disposed at the top of the damping spring 208.

[0024] like Figure 3 As shown, in this preferred embodiment, the number of the anti-seismic slide 202, guide rod 203, anti-seismic slide seat 204, anti-seismic movable rod 205, spiral spring 206, anti-seismic fixed seat 207, damping spring 208, and anti-seismic support rod 209 are all four, and they are distributed in a mirror symmetrical manner. The anti-seismic movable rod 205 is fixedly connected to the anti-seismic support rod 209 and the bottom surface of the explosion-proof transport box 1, and the anti-seismic support rod 209 passes through the anti-seismic fixed seat 207.

[0025] Furthermore, the fixing device 3 includes a fixing plate 301, a fixing screw 302 fixedly disposed on one side surface of the fixing plate 301, a fixing knob 303 fixedly disposed on one side surface of the fixing screw 302, a limiting seat 304 fixedly disposed on the left and right sides of the fixing plate 301, and a limiting slide rod 305 disposed inside the limiting seat 304; the limiting slide rod 305 is fixedly connected to the inner wall of the explosion-proof transport box 1, a shaft seat is provided at the connection between the fixing plate 301 and the fixing screw 302, the fixing screw 302 penetrates through the explosion-proof transport box 1, and a thread is provided at the connection between the explosion-proof transport box 1 and the fixing screw 302.

[0026] like Figure 4As shown, the extinguishing device 5 includes a cover 501, a plurality of storage tanks 502 disposed inside the cover 501, a supply pipe 503 fixedly disposed on the bottom surface of the storage tanks 502, a pressure pump 504 fixedly disposed on the bottom surface of the supply pipe 503, a diversion hose 505 with one axial end disposed on one side surface of the pressure pump 504, and a nozzle 506 fixedly disposed on the other axial end of the diversion hose 505. A temperature sensor 507 is disposed at the bottom of the pressure pump 504.

[0027] Working Principle: When it is necessary to secure explosive materials, the operator rotates the securing knob 303, which drives the securing screw 302 to rotate. Since the securing screw 302 is threadedly connected to the explosion-proof transport box 1, the rotation of the securing screw 302 causes it to move axially, thereby moving the securing plate 301. During this movement, the securing plate 301 is restricted by the limiting seat 304 and the limiting slide rod 305, and can only move along the direction of the limiting slide rod. Ultimately, the securing plate 301 fits tightly against the packaging of the explosive materials, firmly securing the explosive materials inside the explosion-proof transport box 1, preventing them from causing danger due to shaking or collision during transportation. During transportation, the vehicle's movement generates various vibrations. When vibrations occur, the shock-absorbing support device 2 begins to function. After the explosion-proof transport box 1 is subjected to vibration, it transmits the vibration to the anti-vibration movable rod 205 and the anti-vibration support rod 209. The anti-vibration movable rod 205 drives the anti-vibration slide block 204 to slide on the guide rod 203. During the sliding process, the spiral spring 206 undergoes elastic deformation, absorbing some of the vibration energy. At the same time, the anti-vibration support rod 209 exerts pressure on the damping spring 208, causing the damping spring 208 to compress or extend, further absorbing and buffering the vibration energy. Through the synergistic effect of the spiral spring 206 and the damping spring 208, the vibration amplitude transmitted to the explosion-proof transport box 1 is greatly reduced, thereby reducing the risk of explosion of civil explosive materials due to vibration. During the process, the temperature sensor 507 monitors the temperature inside the explosion-proof transport box 1 in real time. When the temperature inside the box rises abnormally due to various reasons during transportation and reaches a preset threshold, the temperature sensor 507 will transmit a signal to the pressure pump 504. After receiving the signal, the pressure pump 504 starts, extracting the extinguishing medium from the storage tank 502 through the supply pipe 503 and delivering it to each nozzle 506 through the diversion hose 505. The nozzles 506 spray the extinguishing medium into the explosion-proof transport box 1. Fire extinguishing agents can quickly reduce the temperature inside the container, inhibit the combustion reaction, prevent the spread of fire and explosion, and thus ensure the safe transportation of civilian explosives.
