[0002] Explosion-proof containers, as specialized safety disposal equipment, are canister-shaped containers used for the temporary storage, transfer, and disposal of suspected explosives. Their core function is to withstand and reduce the blast wave and fragmentation effects of explosives within a controllable range, thereby minimizing harm to surrounding personnel and property. However, traditional explosion-proof containers present significant technical challenges in operation.

[0003] Therefore, it is necessary to provide a new explosion-proof container to solve the above-mentioned technical problems. Utility Model Content

[0004] The main purpose of this utility model is to provide an explosion-proof container, which aims to solve the technical problem of high operational difficulty in the use of explosion-proof containers.

[0005] To achieve the above objectives, this utility model proposes an explosion-proof container, comprising: The tank body includes an outer tank and an inner tank, with the inner tank disposed inside the outer tank; A sealing assembly includes a fixed plate, multiple sealing plates, and multiple elastic elements. The fixed plate is disposed on the inner tank and has placement holes. Each sealing plate is rotatably disposed on the fixed plate and arranged sequentially along the circumference of the placement holes. The number of elastic elements is equal to the number of sealing plates, and each elastic element is disposed at the connection between the corresponding sealing plate and the fixed plate. Each elastic element can drive the corresponding sealing plate to rotate, so that the sealing plates are sequentially adjacent to each other to seal the placement holes.

[0006] In one embodiment, each of the sealing plates is rotatably mounted on the fixed plate via a rotating shaft. The elastic element is a torsion spring, which is sleeved on the rotating shaft. The first end of the torsion spring is connected to the fixed plate, and the second end of the torsion spring is connected to the sealing plate.

[0007] In one embodiment, each of the sealing plates is provided with two first connecting blocks at intervals, and the fixing plate is provided with two second connecting blocks at intervals corresponding to the positions of each of the sealing plates. The two first connecting blocks are disposed between the two second connecting blocks. The rotating shaft passes through one of the second connecting blocks, the two first connecting blocks and the other second connecting block in sequence. The torsion spring is disposed between the two first connecting blocks and sleeved on the rotating shaft. The first end of the torsion spring is inserted into the fixing plate and the second end of the torsion spring is inserted into the sealing plate.

[0008] In one embodiment, each of the sealing plates is disposed on the side of the fixing plate facing the bottom of the inner tank; each of the sealing plates is inclined from the outside to the inside from the side closer to the fixing plate to the side farther away from the fixing plate.

[0009] In one embodiment, the fixing plate is provided with a pressure relief hole.

[0010] In one embodiment, there are multiple pressure relief holes, which are evenly spaced along the circumferential direction of the fixing plate.

[0011] In one embodiment, the inner tank includes a first body and a first inclined portion disposed on the top of the first body, the outer tank includes a second body and a second inclined portion disposed on the top of the second body, the tank body further includes a connecting cylinder, the connecting cylinder connecting the first inclined portion and the second inclined portion; the pressure relief hole is disposed on the outer edge of the fixing plate and is correspondingly disposed to the first inclined portion.

[0012] In one embodiment, an annular stop is provided on the inner wall of the bottom of the connecting cylinder. The annular stop is used to cover the pressure relief hole. The annular stop is inclined from the outside to the inside along the direction from the top of the tank to the bottom of the tank.

[0013] In one embodiment, the inner tank, the outer tank, and the connecting cylinder enclose a receiving space, and a buffer element is provided in the receiving space.

[0014] In one embodiment, the explosion-proof container further includes two grip handles, which are symmetrically arranged on the outer surface of the outer container.

[0015] The technical solution of this utility model uses elastic elements to drive the corresponding sealing plates to rotate, so that the sealing plates sequentially abut and seal the placement holes. This reduces the operational difficulty for operators when using the explosion-proof canister, thereby ensuring the safety of the operators. In this embodiment, the canister body consists of a double-layer structure of an outer canister and an inner canister, which improves the explosion-proof performance of the canister. Placement holes are provided on the fixed plate for operators to place suspected explosives into the canister. Each sealing plate is rotatably mounted on the fixed plate. Elastic elements provide elastic force to drive the sealing plates to rotate, so that each sealing plate sequentially abuts and seals the placement holes. By driving the sealing plates to rotate using elastic elements to seal the placement holes, the operational difficulty for operators when using the explosion-proof canister is reduced, thereby ensuring the safety of the operators. Specifically, when using the explosion-proof canister, the operator places the suspected explosive into the placement hole. The suspected explosive will then push open the sealing plate and enter the canister by its own weight. Subsequently, the sealing plate is rotated by the elastic element, which can block the placement hole and seal the explosion-proof canister. In this process, the operator only needs to place the suspected explosive into the placement hole, without the need for complicated operations such as closing and locking the canister lid, which can greatly reduce the difficulty of operation for the operator when using the explosion-proof canister.

[0024] Explosion-proof containers, as specialized safety disposal equipment, are canister-shaped containers used for the temporary storage, transfer, and disposal of suspected explosives. Their core function is to withstand and reduce the blast wave and fragmentation effects of explosives within a controllable range, thereby minimizing harm to surrounding personnel and property. In actual production and research, researchers have found that traditional explosion-proof containers mainly consist of a container body and a lid. During use, operators must first place the suspected explosive into the container, then place the lid on the container body and lock it in place using a locking mechanism. In other words, operators need to place the suspected explosive into the container, then close and lock the lid, which significantly increases the operational difficulty of using explosion-proof containers. Furthermore, when faced with uncontrollable suspected explosives, the explosive may detonate while operators are sealing the explosion-proof container, threatening their safety.

[0025] This utility model proposes an explosion-proof container, aiming to solve the technical problem of high operational difficulty in the use of explosion-proof containers.

[0026] Please see Figures 1 to 4 In one embodiment of this utility model, the explosion-proof canister includes a canister body 100 and a sealing assembly 200. The canister body 100 includes an outer canister 110 and an inner canister 120, with the inner canister 120 disposed inside the outer canister 110. The sealing assembly 200 includes a fixing plate 210, multiple sealing plates 220, and multiple elastic members. The fixing plate 210 is disposed in the inner canister 120 and has a placement hole 211. Each sealing plate 220 is rotatably disposed on the fixing plate 210 and arranged sequentially along the circumference of the placement hole 211. The number of elastic members is equal to that of the sealing plates 220, and each elastic member is disposed at the connection between the corresponding sealing plate 220 and the fixing plate 210. Each elastic member can drive the corresponding sealing plate 220 to rotate so that each sealing plate 220 is sequentially adjacent to each other, sealing the placement hole 211.

[0027] The technical solution of this utility model uses elastic elements to drive the corresponding sealing plates 220 to rotate, so that each sealing plate 220 sequentially abuts and seals the placement hole 211. This reduces the operational difficulty for operators when using the explosion-proof canister, thereby ensuring the safety of the operators. In this embodiment, the canister 100 consists of a double-layer structure composed of an outer canister 110 and an inner canister 120, which improves the explosion-proof performance of the canister. The placement hole 211, which is provided on the fixed plate 210, allows operators to place suspected explosives into the canister 100. Each sealing plate 220 is rotatably mounted on the fixed plate 210. The elastic elements provide elastic force to drive each sealing plate 220 to rotate, so that each sealing plate 220 sequentially abuts and seals the placement hole 211. By driving the sealing plates 220 to rotate and seal the placement hole 211 through the elastic elements, the operational difficulty for operators when using the explosion-proof canister is reduced, thereby ensuring the safety of the operators. Specifically, when using the explosion-proof container, the operator places a suspected explosive into the placement hole 211. The explosive, by its own weight, pushes open the sealing plate 220 and enters the container body 100. Subsequently, the sealing plate 220 is rotated by an elastic element, sealing the placement hole 211 and thus closing the explosion-proof container. In this process, the operator only needs to place the suspected explosive into the placement hole 211, eliminating the need for complex operations such as closing and locking the container lid, significantly reducing the operational difficulty for the operator. This explosion-proof container is applied in the field of explosion-proof equipment technology.

[0028] In one embodiment of this utility model, each sealing plate 220 is rotatably mounted on a fixed plate 210 via a rotating shaft. The elastic element is a torsion spring, which is sleeved on the rotating shaft. The first end of the torsion spring is connected to the fixed plate 210, and the second end of the torsion spring is connected to the sealing plate 220. In this embodiment, a torsion spring is selected as the elastic element, and the sealing plate 220 is driven to rotate by the torsion spring to seal the placement hole 211. It has the characteristics of simple structure and can reduce the manufacturing difficulty of the explosion-proof can. In a specific embodiment, each sealing plate 220 is provided with two first connecting blocks 221 at intervals. The fixed plate 210 is provided with two second connecting blocks at intervals corresponding to the positions of each sealing plate 220. The two first connecting blocks 221 are disposed between the two second connecting blocks. The rotating shaft passes through one of the second connecting blocks, the two first connecting blocks 221, and the other second connecting block in sequence. The torsion spring is disposed between the two first connecting blocks 221 and sleeved on the rotating shaft. The first end of the torsion spring is inserted into the fixed plate 210, and the second end of the torsion spring is inserted into the sealing plate 220. In this embodiment, the number of sealing plates 220 and the number of torsion springs are both six. By setting the number of sealing plates 220 to six, it ensures the sealing effect of the placement hole 211 when the sealing plates 220 are sequentially adjacent, and also allows the sealing plates 220 to open the placement hole 211 as much as possible when a suspected explosive is placed, thus preventing the suspected explosive from being stuck when placed into the container 100. Alternatively, the number of sealing plates 220 and torsion springs can be designed to be three, four, five, or other quantities depending on actual needs.

[0029] In one embodiment of this utility model, each sealing plate 220 is disposed on the side of the fixing plate 210 facing the bottom of the inner tank 120; each sealing plate 220 is inclined from the outside to the inside from the side closer to the fixing plate 210 to the side farther away from the fixing plate 210. In this embodiment, each sealing plate 220 is installed below the fixing plate 210 and is inclined, which can form an inverted cone structure when the sealing plates 220 are sequentially adjacent. When subjected to the impact generated by the explosion of a suspected explosive, the sealing plates 220 can be effectively prevented from deforming, thereby ensuring the reliability of each sealing plate 220 when sealing the placement hole 211.

[0030] In one embodiment of this utility model, a pressure relief hole 212 is provided on the fixing plate 210. In this embodiment, by providing a pressure relief hole 212 on the fixing plate 210, the internal pressure can be quickly released in the event of a suspected explosive detonation, thereby protecting the tank 100 from being destroyed. In a specific embodiment, there are multiple pressure relief holes 212, which are evenly spaced along the circumference of the fixing plate 210. The number of pressure relief holes 212 can be six, or different numbers can be provided on the fixing plate 210 according to actual needs.

[0031] In one embodiment of this utility model, the inner tank 120 includes a first body 121111 and a first inclined portion 122 disposed on the top of the first body 121111; the outer tank 110 includes a second body and a second inclined portion 112 disposed on the top of the second body; the tank body 100 also includes a connecting cylinder 130, which connects the first inclined portion 122 and the second inclined portion 112; a pressure relief hole 212 is disposed on the outer edge of the fixing plate 210 and is correspondingly disposed to the first inclined portion 122. Both the first inclined portion 122 and the second inclined portion 112 are inclined from the outside inwards. In this embodiment, by designing the top of the tank body 100 as a tapered structure with gradually decreasing cross-sectional dimensions, the stability of the tank body 100 can be improved, reducing the risk of the explosion-proof tank tipping over during use. Furthermore, by correspondingly distributing the pressure relief hole 212 to the first inclined portion 122, the ejected shock wave and fragments can be guided secondary to change their ejection direction. Simultaneously, it can more efficiently dissipate explosion energy and accelerate the attenuation of the shock wave.

[0032] In one embodiment of this utility model, an annular stop 131 is provided on the inner wall of the bottom of the connecting cylinder 130. The annular stop 131 is used to shield the pressure relief hole 212. The annular stop 131 is inclined from the outside to the inside along the direction from the top to the bottom of the tank body 100. In this embodiment, by providing an inclined annular stop 131 on the inner wall of the bottom of the connecting cylinder 130, a reversing structure can be formed to change the direction of the shock wave and fragments ejected from the pressure relief hole 212 again, thereby containing the shock wave and fragments ejected from the pressure relief hole 212 as much as possible in the explosion-proof tank.

[0033] In one embodiment of this invention, an inner tank 120, an outer tank 110, and a connecting cylinder 130 are arranged to form a receiving space, within which a buffer element 140 is provided. In this embodiment, by filling the space between the inner tank 120 and the outer tank 110 with the buffer element 140, the explosion energy can be greatly consumed and attenuated, thus improving the explosion-proof performance of the explosion-proof can. In a specific embodiment, the buffer element 140 can be dry sand, ceramic particles, or high-performance composite materials (such as foam, Kevlar fiber, etc.). In a specific embodiment, a reinforcing block is provided between the outer surface of the bottom of the inner tank 120 and the inner surface of the bottom of the outer tank 110; the reinforcing block is used to improve the structural strength of the explosion-proof can.

[0034] In one embodiment of this utility model, the explosion-proof container further includes two grip handles 300, which are symmetrically arranged on the outer surface of the outer container 110. In this embodiment, by providing grip handles 300 on the explosion-proof container, it can be gripped by operators, thereby reducing the difficulty for operators to carry and move the explosion-proof container.

[0035] It should be noted that, to ensure the structural strength of the explosion-proof canister, both the inner canister 120 and the outer canister 110 must be made of high-strength metal materials. To prevent the sealing assembly 200 from being blown away when the suspected explosive device detonates, the explosion-proof canister of this invention fixes the fixing plate 210 of the sealing assembly 200 below the first inclined portion 122 of the inner canister 120. Similarly, to ensure the sealing effect of the sealing plate 220 when sealing the placement hole 211, the sealing plate 220 should be made of high-strength metal material to ensure that it will not deform when subjected to the impact of the suspected explosive device's explosion. Furthermore, the elastic element should also be a torsion spring capable of providing a large elastic force to prevent the sealing plate 220 from overturning when subjected to the impact of the suspected explosive device's explosion.

[0036] The above description is merely an exemplary embodiment of the present utility model and does not limit the scope of protection of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the scope of protection of the present utility model.
