Description

Technical Field

[0001] The invention belongs to the technical field of explosive article storage facilities, and in particular relates to a mobile explosives storehouse with anti-theft and explosion-discharging functions. Background Art

[0002] Dangerous goods warehouses are places for storing and keeping dangerous goods such as flammable, explosive, toxic and harmful materials. Because dangerous goods warehouses must ensure safety, existing dangerous goods warehouses are basically located in very remote locations. During the construction of various projects, it is often necessary to prepare one or two days of explosives. It is also very inconvenient to go to a remote dangerous goods warehouse to get explosives every day. Therefore, a temporary mobile explosives warehouse is basically installed on the construction site. The mobile explosives warehouse has the characteristics of simple installation, convenient transportation, short construction period and repeated use. In particular, some projects have a short construction period. After the project is completed, the mobile explosives warehouse can be immediately disassembled and moved to other construction sites for continued use. Mobile explosives depots are generally equipped with explosion vents. When an explosion occurs inside the mobile explosives depot, the shock wave generated by the explosion can be transmitted to the outside through the explosion vent, thus preventing the explosives depot from becoming a closed bomb. In order to make the explosion vent play a good explosion venting function, the cross-sectional area of ​​the explosion vent will be large, and outsiders can easily pass through the explosion vent to enter the explosives depot, which may lead to the theft of explosives. In addition, fragments generated by the explosion will also fly to the outside through the explosion vent, causing safety hazards. Summary of the invention

[0003] In view of the drawbacks existing in the prior art, the present invention provides a mobile explosives depot with anti-theft and explosion-proof functions. The mobile explosives depot is provided with a multi-layer protective structure. The provided protective structure will not affect the performance of the explosion-proof opening, and can prevent outsiders from entering the mobile explosives depot from the explosion-proof opening. The protective structure can also block fragments produced by the explosion, thereby improving safety performance.

[0004] The inventive objective of the present invention is achieved through the following technical scheme: a mobile explosives storehouse with anti-theft and explosion-proofing functions, comprising an explosives storehouse body, an inlet and outlet arranged on the explosives storehouse body, explosion-proof doors arranged at the inlet and outlet positions, an explosion-proofing port arranged on the explosives storehouse body, a multi-layer parallel protective structure which separates the explosion-proofing port from the inner cavity of the explosives storehouse body, with intervals left between adjacent protective structures, the protective structure comprising a fixing ring of an annular structure, the fixing ring fixedly arranged on the inner wall of the explosives storehouse body, a plurality of parallel steel pipes fixedly arranged on the inner side of the fixing ring, with intervals left between adjacent steel pipes, and steel pipes in protective structures of different levels arranged in an alternating manner.

[0005] In the above scheme, if the explosive items in the explosives depot explode, the shock wave generated by the explosion will pass through the spacing between the steel pipes and the spacing between the protective structures, and then spread to the outside through the explosion vent. The setting of the protective structure will not affect the explosion venting function of the explosion vent. The steel pipes in the protective structures of different levels are staggered, so that the cooperation between the multi-layer protective structures can be used to prevent outsiders from entering the explosives depot, playing a good protective and anti-theft role. At the same time, when the shock wave generated by the explosion passes through the steel pipe, if there are fragments in the shock wave, the steel pipes on the protective structure can block the fragments and prevent the fragments from causing damage to the outside world. The multi-layer protective structure can achieve multi-level blocking of fragments, which can block most large-volume fragments, thereby improving safety performance.

[0006] Preferably, the inlet and outlet are arranged on the side of the explosives depot body, the explosion vent is located at the top of the upper end of the explosives depot body, and a protective cover is provided above the explosives depot body; all protective structures are arranged longitudinally from bottom to top, and the fixing rings and steel pipes in the protective structure are arranged horizontally. When the explosive items stored in the explosives depot body explode, due to the setting of the explosion vent, the shock wave generated by the explosion is more likely to spread outward through the explosion vent, so that the explosives depot body can guide the shock wave and discharge the shock wave generated by the explosion upward, thereby reducing the lateral destructive force of the shock wave, thereby shortening the required safety distance. The setting of the protective cover can shield the explosion vent from rain. Providing a multi-layer protective structure on the path that the shock wave must pass through to spread upward can also reduce the destructive force of the shock wave on the outside world, thereby improving safety performance.

[0007] Preferably, the steel pipe is provided with a plurality of vertical through holes, and the through holes on the steel pipe are evenly distributed along the length direction of the steel pipe. The fixing ring is also provided with a plurality of vertical through holes, and the through holes on the fixing ring are distributed in a circle around the central axis of the fixing ring. When the shock wave generated by the explosion passes through the protective structure from bottom to top, it will also pass through the through holes on the steel pipe and the fixing ring, so that the noise generated by the explosion and the shock wave can be reduced and silenced, which is consistent with the principle of the muffler.

[0008] Preferably, the explosive magazine body is provided with a gradually contracting portion from bottom to top, the cross section of the contracting portion is a circular ring structure, the fixing ring is a circular ring structure, and the inner diameters of the fixing rings in the different levels of the protective structure decrease successively from bottom to top. The contracting portion can contract and concentrate the shock wave that spreads upward, so that the shock wave is limited within a certain range, and the damage range of the shock wave is reduced.

[0009] Preferably, the spacing between the steel pipes in the protective structure at different levels is equal, so that the distribution of the steel pipes is more uniform.

[0010] Preferably, except for the bottom protective structure, the angles between the steel pipes in the other protective structures from bottom to top and the steel pipes in the bottom protective structure gradually increase in equal steps, and the sum of the angle A between the steel pipes in the second bottom protective structure and the steel pipes in the bottom protective structure and the angle B between the steel pipes in the top protective structure and the steel pipes in the bottom protective structure is equal to 180°. This arrangement enables the steel pipes on the multi-layer protective structure to cooperate with each other, and can evenly block and protect in all directions, so that the protective structure has good anti-theft and protection functions.

[0011] As a preferred embodiment, the fixing ring is fixed with a plurality of guide rods corresponding to the steel pipes one by one, one end of the steel pipe is sleeved on the corresponding guide rod, and the other end is fixedly connected to the inner side wall of the fixing ring. In actual installation, one end of the steel pipe can be sleeved on the corresponding guide rod first, and then the other end can be fixedly installed on the fixing ring by welding or screwing or bolting, which can make the installation of the steel pipe more convenient. When the steel pipe is impacted by the shock wave, bending deformation may occur. If both ends of the steel pipe are fixedly connected to the fixing ring, the connection between the steel pipe and the fixing ring may break when the steel pipe is bent and deformed, and the steel pipe is directly separated from the fixing ring. The steel pipe will be broken and rushed to the outside world with the impact, which is easy to cause certain damage to the outside world. The above scheme is used to install the steel pipe. When the steel pipe is subjected to the shock wave and is bent and deformed, one end of the steel pipe sleeved on the guide rod will be separated from the guide rod, while the other end can still be fixed on the fixing ring, which can reduce the possibility of separation of the steel pipe from the fixing ring and avoid the steel pipe from rushing to the outside world with the shock wave.

[0012] Preferably, the protective cover is a spherical structure, and the protective cover is fixedly arranged on the explosives storehouse body, and the surroundings of the protective cover protrude outward relative to the surroundings of the upper end of the explosives storehouse body. The setting of the protective cover can play a role in keeping out rain, and prevent rainwater from entering the explosives storehouse body through the explosion vent. The protective cover is made of soft material, such as plastic. Softer materials are easy to break under the impact of shock waves, so that the installation of the protective cover does not affect the performance of the pressure relief port. At the same time, when the protective cover made of softer material is blown away by the shock wave, it can also reduce the destructive force caused by the protective cover to the outside world.

[0013] Compared with the prior art, the present invention has the following beneficial effects: the multi-layer protection structure provided in the present invention enables the present invention to play a good anti-theft, protective and noise reduction role, and will not affect the performance of the explosion vent.
