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 good explosion-proof performance. Background Art

[0002] Dangerous goods warehouse is a place 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 reassembled to other construction sites for continued use. The explosion-proof performance of existing mobile explosives warehouses depends on the material and thickness of the wall panels. The explosion-proof performance is poor. In order to ensure safety, it is necessary to reserve sufficient safety distance around the mobile explosives warehouse. When some projects are small in scale, it is difficult to reserve enough space to meet the safety distance of the mobile explosives warehouse, which is easy to cause safety hazards. Summary of the invention

[0003] The present invention aims at the drawback that the mobile explosives storehouse in the prior art has poor explosion-proof performance, and provides a mobile explosives storehouse with good explosion-proof performance. The mobile explosives storehouse is partially buried in the ground, and explosive materials are loaded into the mobile explosives storehouse at a position below the ground surface, which can effectively improve the explosion-proof performance of the mobile explosives storehouse.

[0004] The inventive objective of the present invention is achieved through the following technical scheme: a mobile explosives storehouse with good explosion-proof performance, comprising a pit located on the ground and an explosives storehouse body partially buried in the pit, the space in the explosives storehouse body for storing explosive items is located below the ground surface, an entrance and an exit are opened at a position above the ground surface on the explosives storehouse body, an explosion-proof door is provided at the entrance and exit positions, a pile of sandbags arranged around the explosives storehouse body is stacked outside the explosives storehouse body, and a passage is left on the side of the sandbag pile at the explosion-proof door position.

[0005] In the above scheme, the main body of the explosives storehouse is partially buried below the ground surface, and the explosive materials are stored in the space below the ground surface inside the main body of the explosives storehouse. The soil and sandbag piles around the pit are arranged around the main body of the explosives storehouse. When the explosive materials in the main body of the explosives storehouse explode, the first thing to be affected by the impact force is the inner wall of the space below the ground surface inside the main body of the explosives storehouse. If the main body of the explosives storehouse below the ground surface has a tendency to expand and burst outward due to the impact of the explosion, the sandbag piles and the soil around the pit will hinder this tendency. When the main body of the explosives storehouse is damaged by the impact force generated by the explosion, the soil and sandbag piles around the pit can block the shock wave and the broken fragments in the horizontal direction, which can reduce the harm caused by the explosion, thereby shortening the required safety distance.

[0006] Preferably, the explosives storehouse body includes at least two chambers and a storehouse bottom, the storehouse bottom and the chambers are longitudinally stacked in sequence, the upper and lower adjacent chambers and the lowermost chamber and the storehouse bottom are detachably sealed and fixedly connected, and the inner cavities of the upper and lower adjacent chambers are sequentially connected, the chambers and the storehouse bottom are respectively fixed with flanges, and the flanges are provided with mounting holes, and bolts are installed between the flanges on the upper and lower adjacent chambers and between the flanges on the chambers and the flanges on the storehouse bottom to achieve detachable fixed connection between the upper and lower adjacent chambers and between the chambers and the storehouse bottom, and the bolts are arranged at the location of the mounting holes. The explosives storehouse body is divided into at least two chambers and a storehouse bottom, which can be easily moved and transported. The chambers and the chambers and the storehouse bottom are more firmly and conveniently connected by the structure of flanges and bolts.

[0007] Preferably, the flange is a circular ring structure, the flange is sleeved and fixedly arranged outside the corresponding chamber or the bottom of the chamber, the chamber end protrudes outward relative to the corresponding flange, a number of reinforcing plates vertically arranged around the chamber are fixedly arranged between the outer side of the chamber and the flange, the reinforcing plates are perpendicular to the outer side of the chamber, the reinforcing plates protrude outward relative to the end of the chamber, and the inner side of the protruding part is provided with an inclined surface expanding outward, the reinforcing plates on the mutually matching flanges are staggered, and the reinforcing plates are fitted with the outer side walls of the adjacent chambers. The provision of the reinforcing plates can enhance the strength of the connection structure between the flange and the outer side of the chamber, and when assembling the explosives depot body, the inclined surface on the reinforcing plates can play a certain guiding role in the installation of the chamber, making it easier to align the upper and lower adjacent chambers during assembly.

[0008] Preferably, the upper and lower ends of the chamber located at the uppermost end are both annular structures, and the diameter of the upper end of the chamber is smaller than the diameter of the lower end, and the connection between the lower end and the upper end of the chamber is a structure that gradually closes upwards, the upper end of the chamber protrudes upwards relative to the sandbag pile, the upper end of the chamber is provided with an explosion vent, and a protective cover is provided directly above the chamber, a space margin is left between the lower end surface of the protective cover and the upper end of the chamber located at the uppermost end, and the surrounding of the protective cover protrudes outwards relative to the upper end of the chamber. The arrangement of the pit and the sandbag pile makes it difficult for the impact force generated by the explosion to continue to spread horizontally, and can only spread upwards. The closing structure of the chamber located at the uppermost end can close the impact force generated by the explosion, so that the shock wave is concentrated upwards through the explosion vent to first break the protective cover, and then spread to the outside world, reducing the lateral destructive force. The arrangement of the protective cover can play a role in keeping out rain, preventing rainwater from entering the explosives depot through the explosion vent.

[0009] Preferably, except for the chamber located at the top, the other chambers are of circular ring structure, and the chamber of the circular ring structure includes at least two arc plates that can be assembled together, and the left and right ends of each arc plate are respectively fixedly connected with outwardly protruding connecting plates, and the connecting plates on adjacent arc plates are fixedly connected by bolts.

[0010] Preferably, the protective cover is a spherical structure, and the upper end of the chamber located at the top is fixedly connected with a plurality of vertically arranged connecting rods, the upper ends of the connecting rods are fixedly connected to the lower end surface of the protective cover, and a protective net is fixedly arranged between adjacent connecting rods, and the edge height of the protective cover is not higher than the height of the upper end of the chamber located at the top. The arrangement of the connecting rods forms a space margin between the lower end surface of the protective cover and the upper end of the top chamber, and the space margin can be used for ventilation in the explosives depot body. In order to prevent birds and other creatures from entering the explosives depot body, a protective net is installed between adjacent connecting rods. By connecting the upper end of the connecting rod with the protective cover, it can not only play a role in installing the protective cover, but also because the connection area between the top of the connecting rod and the protective cover is small, the installation of the protective cover will not be too firm, so that the impact force generated by the explosion can break open the protective cover and play a role in pressure relief. The protective cover is made of soft material, such as plastic. Softer materials are easily broken 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, the destructive force caused by the protective cover to the outside world can be reduced.

[0011] Preferably, the bottom of the warehouse bottom is a curved structure, and a support frame for supporting the warehouse bottom is fixedly connected to the bottom of the warehouse bottom. The setting of the support frame allows the warehouse bottom to be stably placed on a plane, and also allows the warehouse bottom to stand sideways during transportation, thereby reducing the floor space required for transporting the warehouse bottom.

[0012] Preferably, the lower half of the sandbag pile is located below the ground surface and between the inner wall of the pit and the outer wall of the explosive magazine body, and the upper half of the sandbag pile is located above the ground surface. The lower half of the sandbag pile is a vertically stacked circular ring structure, and the outer wall of the upper half of the sandbag pile gradually converges inward from bottom to top. If the lower half of the explosive magazine body located below the ground surface is directly buried with sand, when the explosive magazine body needs to be moved, the sand around the explosive magazine body needs to be excavated to move the explosive magazine body. Because the workload of manually excavating sand is large, excavators are generally used for excavation, and excavators excavating sand are prone to collide with the explosive magazine body, thereby causing damage to the explosive magazine body. When the lower half of the explosive magazine body is buried with a sandbag pile, when the explosive magazine needs to be moved, the method of manually carrying sandbags is more labor-saving than the method of manually excavating sand, and it is not easy to cause damage to the explosive magazine body.

[0013] Preferably, the sandbags in the sandbag pile are filled with sand dug out when digging the pit. The sandbag pile is formed by a large number of sandbags piled up, and the sand dug out from the on-site pit is used to fill the sandbags. There is no need to prepare additional fillers in the sandbags, and there is no need to process the excavated sand. It is more convenient. When the project is completed and the explosives storehouse is no longer needed, the explosives storehouse body is removed from the pit, and the sand in the sandbags can be filled back into the pit. If the sand dug when digging the pit is not enough to fill the required number of sandbags, sand can be prepared separately for filling.

[0014] Preferably, the sandbags in the sandbag pile are provided with zippers, so that the sandbags can be reused.

[0015] Compared with the prior art, the present invention has the following beneficial effects: the present invention has good explosion-proof performance, can effectively shorten the required safety distance, and enables the present invention to be used on smaller sites.

DETAILED DESCRIPTION

[0024] The present invention will be further described below with reference to the embodiments shown in the accompanying drawings:

[0025] Example 1

[0026] like Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, a mobile explosives depot with good explosion-proof performance comprises a pit 1 located on the ground and an explosives depot body 2 partially buried in the pit 1. The space in the explosives depot body 2 for storing explosive items is located below the ground surface. An inlet and outlet 3 is provided on the explosives depot body 2 above the ground surface. An explosion-proof door 4 is provided at the inlet and outlet 3. A pile of sandbags 5 arranged around the explosives depot body 2 is stacked outside the explosives depot body 2. The lower half of the sandbag pile 5 is located below the ground surface and between the inner wall of the pit 1 and the outer wall of the explosives depot body 2. The upper half of the sandbag pile 5 is located above the ground surface. The lower half of the sandbag pile 5 is a vertically stacked circular ring structure. The outer wall of the upper half of the sandbag pile 5 gradually closes inward from bottom to top. The sandbags in the sandbag pile 5 are filled with sand dug out when digging the pit 1. Zippers are provided on the sandbags in the sandbag pile 5. A passage 6 is left on the side of the sandbag pile 5 at the position of the explosion-proof door 4.

[0027] In order to facilitate the transportation of the explosive magazine body 2, the explosive magazine body 2 includes three chambers and a chamber bottom 7. The three chambers include a bottom chamber 8, a middle chamber 9 and a top chamber 10. The explosive magazine body 2 is composed of a chamber bottom 7, a bottom chamber 8, a middle chamber 9 and a top chamber 10 from bottom to top. The chamber bottom 7, the bottom chamber 8, the middle chamber 9 and the top chamber 10 are detachably sealed and fixedly connected in sequence, and the inner cavities of the upper and lower adjacent chambers are connected in sequence. The bottom chamber 8 and the middle chamber 9 are both annular structures. The bottom chamber 8 is located below the ground surface, and the main part of the middle chamber 9 is located above the ground surface. The inlet and outlet 3 are arranged on the middle chamber 9. The upper and lower ends of the top chamber 10 are both annular structures. The diameter of the upper end of the top chamber 10 is smaller than the diameter of the lower end, and the connection between the lower end and the upper end of the top chamber 10 is a structure that gradually converges upward, and the side wall cross-section of the converged part is an S-shaped structure. The upper end of the top chamber 10 protrudes upward relative to the sandbag pile 5, and an explosion vent 11 is provided at the upper end of the top chamber 10. A protective cover 12 with a spherical structure is provided directly above the top chamber 10, and the protective cover 12 is made of soft plastic. There is a space margin between the lower end surface of the protective cover 12 and the upper end of the top chamber 10, and the surrounding of the protective cover 12 protrudes outward relative to the upper end of the top chamber 10. A plurality of vertically arranged connecting rods 13 are fixedly connected to the upper end of the top chamber 10, and the upper ends of the connecting rods 13 are fixedly connected to the lower end surface of the protective cover 12. A protective net 14 is fixedly provided between adjacent connecting rods 13, and the edge height of the protective cover 12 is not higher than the height of the upper end of the top chamber 10. The bottom of the warehouse bottom 7 is a curved structure, and a support frame 15 for supporting the warehouse bottom 7 is fixedly connected to the bottom of the warehouse bottom 7. The arrangement of the support frame 15 enables the bin bottom 7 to be stably placed on a plane, and the gap between the support frame 15 and the bottom of the bin bottom 7 is filled with sand, so that the bin bottom 7 can be subjected to a more uniform force.

[0028] The chamber and the bottom 7 are respectively fixed with flanges 16 of annular structure, which are sleeved and fixedly arranged outside the corresponding chamber or the bottom 7, and the flanges 16 are provided with mounting holes 17. Bolts are installed between the flanges 16 on the upper and lower adjacent chambers and between the flanges 16 on the chamber and the flanges 16 on the bottom 7 to achieve detachable fixed connection between the upper and lower adjacent chambers and between the chamber and the bottom 7, and the bolts are arranged at the position of the mounting holes 17. The chamber end protrudes outward relative to the corresponding flange 16, and a plurality of reinforcing plates 18 vertically arranged around the chamber are fixedly arranged between the outer side surface of the chamber and the flange 16. The reinforcing plates 18 are perpendicular to the outer side surface of the chamber, and the reinforcing plates 18 protrude outward relative to the chamber end, and the inner side of the protruding part is provided with an outwardly expanding inclined surface 19, and the reinforcing plates 18 on the mutually matching flanges 16 are staggered, and the reinforcing plates 18 are in contact with the outer side walls of the adjacent chambers.

[0029] like Figure 5As shown, since the actual size of the explosives magazine body 2 is relatively large, even if the explosives magazine body 2 is divided into a plurality of bins and a bin bottom 7, the actual size of each bin is still relatively large, which is not convenient for transportation. In view of this situation, the bottom bin 8 and the middle bin 9 are designed to be formed by splicing three arc plates 20, respectively. The left and right ends of each arc plate 20 are respectively fixedly connected with a connecting plate 21 protruding outwards, and the connecting plates 21 on adjacent arc plates 20 are fixedly connected by bolts, and the inlet and outlet 3 are arranged on one of the arc plates 20 on the middle bin 9. In this way, the arc plates 20 can be stacked and transported, which can reduce the space occupied when the bins are moved and facilitate transportation.

[0030] In actual use, the warehouse bottom 7 and the bottom chamber 8 are buried in the pit 1 below the ground surface, the middle chamber 9 and the top chamber 10 are located above the ground surface, the explosion-proof door 4 is installed on the middle chamber 9, and the explosive items are stored in the bottom chamber 8. In order to facilitate the removal of explosive items, a ladder or lifting device can be installed in the bottom chamber 8.

[0031] Example 2

[0032] like Figure 5 As shown, compared with Example 1, the difference of Example 2 is that the folded portion on the uppermost chamber is evenly folded from bottom to top, and the outer contour of the folded portion is a truncated cone structure. The bottom of the bin bottom 7 is a plane, and the support frame 15 is not fixedly arranged at the bottom of the bin bottom 7.

[0033] Example 3

[0034] like Figure 6 As shown, compared with Example 1, the difference of Example 3 is that there are two chambers, and the chamber bottom 7 is fixedly connected to the chamber at the bottom.
