DETAILED DESCRIPTION OF THE EMBODIMENTS

[0033] The following will specifically describe the preferred embodiments of the present utility model with reference to the drawings. The drawings form a part of this application and are used together with the embodiments of the present utility model to explain the principle of the present utility model, and are not used to limit the scope of the present utility model.

[0034] A specific embodiment of the present utility model discloses an anti-detonation device, as Figure 1As shown, it includes a housing 1, a pneumatic valve assembly 2 and an explosion-proof assembly 3. The pneumatic valve assembly 2 and the explosion-proof assembly 3 are both arranged on the housing 1. When the housing 1 is in the closed state, the pneumatic valve assembly 2 can control the communication between the inner cavity of the housing 1 and the external environment, so that the inner cavity of the housing 1 maintains a vacuum state or the same air pressure as the outside; the explosion-proof assembly 3 can discharge the gas in the housing 1 when the air pressure in the inner cavity of the housing 1 rises abnormally and prevent the explosion or combustion of the explosive in the inner cavity, which will affect the surrounding environment and cause the surrounding explosives to detonate.

[0035] The housing 1 includes an upper housing 11 and a lower housing 12. The upper housing 11 and the lower housing 12 cooperate to form an inner cavity, and the explosive is placed in the inner cavity. One end of the upper housing 11 is movably connected to the lower housing 12, and the other end is connected by a fixing member.

[0036] Exemplarily, one end of the upper housing 11 is hingedly connected to the lower housing 12, and the other end is connected by a buckle.

[0037] Exemplarily, one end of the upper housing 11 is connected by a hinge to the lower housing 12, and the other end is connected by a block on the upper housing 11 and a slot on the lower housing 12.

[0038] Furthermore, a limiting strip 13 is arranged in the inner cavity of the housing 1. The limiting strip 13 restricts the explosive in the inner cavity to prevent the explosive from displacing in the inner cavity.

[0039] Preferably, the limiting strip 13 is made of an elastic material, such as rubber, etc.

[0040] Both the upper housing 11 and the lower housing 12 are made of fireproof materials, such as foam aluminum alloy, polyurethane foam, etc.

[0041] Preferably, both the upper housing 11 and the lower housing 12 are sprayed with a fireproof coating.

[0042] Preferably, a sealing strip is arranged at the connection between the upper housing 11 and the lower housing 12, so as to keep the inner cavity of the housing 1 in a sealed state.

[0043] Such as Figure 1 As shown, the pneumatic valve assembly 2 includes a channel 21 and a pneumatic valve 22. The channel 21 is connected to the upper housing 11 or the lower housing 12, so that the channel 21 is communicated with the inner cavity of the housing 1. When the housing 1 is in the closed state, a vacuum machine can extract the gas in the inner cavity of the housing 1 through the channel 21, so that the inner cavity of the housing 1 is in a vacuum state. The pneumatic valve 22 is connected to the channel 21, and the pneumatic valve 22 can control the opening and closing of the channel 21, so as to communicate the channel 21 with the inner cavity of the housing 1 and control whether the inner cavity of the housing 1 can exchange gas with the outside.

[0044] Exemplarily, the pneumatic valve 22 is a ball valve or a butterfly valve.

[0045] After placing explosive items in the inner cavity of the housing 1, the upper housing 11 and the lower housing 12 are connected by fixing members to keep the housing 1 in a closed state. The air pressure valve 22 is opened, and the channel 21 is connected to a vacuum machine. After the air in the inner cavity of the housing 1 is extracted by the vacuum machine, the air pressure valve 22 is closed to keep the inner cavity of the housing 1 in a vacuum state, thus facilitating the preservation and flame retardance of explosive items. When it is necessary to take out the explosive items, since the inner cavity of the housing 1 is in a vacuum state and there is a difference from the external atmospheric pressure, it is likely to cause difficulty in separating the upper housing 11 from the lower housing 12. At this time, the air pressure valve 22 is opened to allow external air to enter the inner cavity of the housing 1 through the channel 21, so that the air pressure inside and outside the housing 1 is the same, thus facilitating the separation of the upper housing 11 from the lower housing 12 and opening the housing 1.

[0046] As Figures 1 to 2 shown, the explosion-proof component 3 includes an explosion-proof film 31 and a communication pipe 32, and the communication pipe 32 is connected to the housing 1. Preferably, the communication pipe 32 is connected to the lower housing 12. The explosion-proof film 31 is arranged at the connection between the communication pipe 32 and the housing 1. When the explosive item is in a normal state, the explosion-proof film 31 can seal the inner cavity of the housing 1. When the explosive item has an abnormality resulting in an abnormal increase in air pressure and temperature in the inner cavity, the explosion-proof film 31 is affected by the internal pressure in the inner cavity of the housing 1 and ruptures, enabling the gas in the inner cavity of the housing 1 to enter the communication pipe 32.

[0047] Exemplarily, the explosion-proof film 31 is made of materials such as aluminum or polycarbonate.

[0048] Furthermore, as Figure 2 shown, the explosion-proof component 3 further includes a storage tank 33, and the storage tank 33 is communicated with the communication pipe 32. The storage tank 33 is used to store explosion-proof and flame-retardant liquid. When the explosion-proof film 31 ruptures, the explosion-proof and flame-retardant liquid stored in the storage tank 33 enters the inner cavity of the housing 1 through the communication pipe 32 to cool down the explosive item and extinguish the open fire.

[0049] Exemplarily, the liquid stored in the storage tank 33 is water.

[0050] Preferably, a liquid injection hole and a liquid discharge hole are provided on the storage tank 33 to facilitate adding or reducing the explosion-proof and flame-retardant liquid in the storage tank 33.

[0051] Preferably, as Figure 3 shown, a one-way exhaust valve 321 is further provided on the communication pipe 32. Through the one-way exhaust valve 321, the gas passing through the communication pipe 32 can be discharged to the external environment when the explosive item has an abnormality. The one-way exhaust valve 321 is a prior art and will not be elaborated here.

[0052] Embodiment 2

[0053] Another specific embodiment of the present invention discloses an anti-detonation device. As Figure 4As shown, the difference from Embodiment 1 is that a one-way exhaust valve 321 is not provided on the connecting pipe 32, and the explosion-proof assembly 3 further includes a fireproof net 34 to prevent a large area of open flames from spraying out after the explosion-proof film 31 is broken due to an abnormality of the explosive product.

[0054] As Figures 4 to 5 shown, the fireproof net 34 is arranged inside the connecting pipe 32, and the shape of the fireproof net 34 matches the cross-sectional shape of the connecting pipe 32. A moving block 341 is arranged on the fireproof net 34, and a moving groove 322 is arranged on the connecting pipe 32. The moving block 341 cooperates with the moving groove 322 to enable the fireproof net 34 to move along the moving groove 322, preventing the fireproof net from shifting and causing flames to escape.

[0055] Furthermore, as Figure 4 shown, a sealing film 331, a fixing block 332, and a spring 333 are arranged at the position where the storage box 33 is connected to the connecting pipe 32. The sealing film 331 is used to seal the storage box 33 to prevent the explosion-proof and flame-retardant liquid in the storage box 33 from flowing out. One end of the fixing block 332 penetrates through the sealing film 331 and is fixedly connected to the storage box 33, and the other end is connected to the fireproof net 34 through the spring 333. A spike portion 342 is arranged on the side of the fireproof net 34 facing the storage box 33, and the spike portion 342 is used to pierce the sealing film 331 to enable the explosion-proof and flame-retardant liquid in the storage box 33 to flow into the inner cavity of the housing 1.

[0056] It can be understood that when the explosive product does not have an abnormality, the spring 333 supports the fireproof net 34 to prevent the spike portion 342 from piercing the sealing film 331, thereby preventing the explosion-proof and flame-retardant liquid from corroding the explosion-proof film 31 and seeping into the inner cavity of the housing 1, resulting in damage to the explosive product; when a large amount of gas is generated due to an abnormality of the explosive product, the explosion-proof film 31 is broken, enabling the gas in the inner cavity of the housing 1 to enter the connecting pipe 32 and pushing the fireproof net 34 to move along the moving groove 322 in the direction close to the sealing film 331. The spring 333 is compressed under the action of the gas generated by the explosive product, causing the spike portion 342 to pierce the sealing film 331, so that the explosion-proof and flame-retardant liquid in the storage box 33 flows into the inner cavity of the housing 1 through the connecting pipe 32, playing an explosion-proof and flame-retardant role in the explosive product and preventing the explosive product from exploding and threatening the surrounding environment, resulting in secondary explosion.

[0057] It can be understood that the anti-secondary explosion device of Embodiment 1 and Embodiment 2 can also be placed in an existing explosion-proof box and used in combination with the existing explosion-proof box, thereby achieving a better anti-secondary explosion effect.

[0058] Compared with the prior art, for the anti-detonation device of the present utility model, by providing a pneumatic valve assembly 2, a vacuum machine can extract the gas in the inner cavity of the housing 1 through the passage 21, thereby ensuring that the inner cavity of the housing 1 is in a vacuum state; by opening the pneumatic valve 22, outside air can enter the inner cavity of the housing 1 through the passage 21, making the air pressure inside and outside the housing 1 consistent, facilitating the differentiation of explosive products, and improving the safety and stability of the storage environment of explosive products. By providing an explosion-proof assembly 3, when abnormal gas is generated by the explosive product, the inner cavity of the housing 1 can be depressurized in a timely manner, and the explosion-proof and flame-retardant liquid stored in the storage tank 33 enters the inner cavity of the housing 1 through the connecting pipe 32, cooling down the explosive product and extinguishing the open flame, thereby preventing further combustion and explosion of the explosive product, improving the safety of the surrounding environment, and preventing the occurrence of secondary explosion. By providing a fireproof net 34, it can prevent a large area of open flame from spraying out after the explosion-proof film 31 ruptures. By providing a spiked portion 342 and a sealing film 331, when an abnormality occurs to the explosive product, the sealing film 331 can be punctured by the spiked portion 342, enabling the explosion-proof and flame-retardant liquid in the storage tank 33 to flow into the inner cavity of the housing 1 through the connecting pipe 32, playing an explosion-proof and flame-retardant role for the explosive product, and preventing the explosion of the explosive product from threatening the surrounding environment and causing secondary explosion. The anti-detonation device of the present utility model can also be placed inside an existing explosion-proof box and used in combination with the existing explosion-proof box, thereby achieving a better anti-detonation effect.

[0059] The above is only the preferred specific implementation manner of the present utility model, but the protection scope of the present utility model is not limited thereto. Any changes or substitutions that can be easily thought of by those skilled in the art within the technical scope disclosed by the present utility model should be covered within the protection scope of the present utility model.
