Description

Technical Field

[0001] The utility model relates to the technical field of explosion-proof tanks, and particularly relates to a flexible composite explosion-proof tank. Background Art

[0002] In the fields of public safety and anti-terrorism and riot control, explosion-proof tanks, as key equipment for dealing with improvised explosive devices, their performance and safety are directly related to the safety of personnel and property. Traditionally, explosion-proof tanks are mostly processed from high-strength metal materials. These rigid explosion-proof structures, with their excellent wave impedance characteristics, can effectively reflect most of the shock waves during the explosion of explosives and disperse and transfer the explosion energy, thus significantly reducing the destructive power of the explosion on the surrounding environment. However, with the continuous increase in the types of explosives, the limitations of traditional rigid explosion-proof tanks have gradually emerged.

[0003] Firstly, due to being made of thick and heavy metal materials, rigid explosion-proof tanks are often heavy and have poor mobility, making it inconvenient to quickly deploy and move in complex and changeable on-site environments. In case of an emergency, this inconvenience may seriously affect the disposal efficiency and even miss the best disposal opportunity.

[0004] Secondly, when a rigid explosion-proof tank bears an explosion shock, although it can effectively disperse and transfer the explosion energy, it may itself become a new hazard source. Especially in extreme cases, the fragments of the rigid explosion-proof tank may fly due to the explosion shock, causing secondary fragment injuries and posing a potential threat to the surrounding personnel;

[0005] During the actual application process of the flexible composite explosion-proof tank, there is also a problem that the height of the detonation support net inside the explosion-proof tank is not easy to adjust, which is particularly prominent when dealing with explosives of larger volume. The detonation support net, as a key component for supporting and fixing explosives, the flexibility of its height directly affects the applicability and disposal efficiency of the explosion-proof tank.

[0006] Specifically, when it is necessary to dispose of explosives of larger volume, if the height of the detonation support net cannot be adjusted accordingly according to the actual size of the explosives, it will result in insufficient internal space in the explosion-proof tank and be unable to effectively accommodate and fix the explosives. This not only increases the operation difficulty and risk during the disposal process but also may affect the protection effect of the explosion-proof tank.

[0007] Therefore, a flexible composite explosion-proof tank is needed to overcome the occurrence of the above problems. Content of the Utility Model

[0008] In order to solve the above problems, the embodiment of the utility model provides a flexible composite explosion-proof tank, achieving the purpose of solving the problems proposed in the background art.

[0009] In order to achieve the above object, the embodiments of the present utility model specifically adopt the following technical solutions: A flexible composite explosion-proof tank, comprising a tank body, a top cover is arranged at the top opening of the tank body, and a height-adjustable explosion-proof net is arranged inside the tank body;

[0010] The height of the explosion-proof net is adjusted through an adjustment assembly.

[0011] As a further improvement of the above technical solution:

[0012] The adjustment assembly includes a plurality of hook ones arranged at equal intervals along the axial direction of the tank body.

[0013] The adjustment assembly includes a lead screw rotatably arranged inside the tank body, a limiting rod fixedly connected inside the tank body, a connecting ring threadedly connected to the outside of the lead screw and slidably arranged outside the limiting rod, and a hook two fixedly connected inside the connecting ring.

[0014] One end of the lead screw is fixedly connected with a rotating block.

[0015] The tank body is composed of a first explosion-proof structure unit and a second explosion-proof structure unit arranged in sequence from inside to outside. Both the first explosion-proof structure unit and the second explosion-proof structure unit include a first flexible explosion-proof layer, a second flexible explosion-proof layer, and a third flexible explosion-proof layer. The second flexible explosion-proof layer is arranged between the first flexible explosion-proof layer and the third flexible explosion-proof layer.

[0016] The beneficial effects of the embodiments of the present utility model are:

[0017] During actual use, the height of the explosion-proof net is adjusted through the adjustment assembly. When the volume of the explosive is large, the height of the explosion-proof net can be lowered to facilitate the accommodation of explosives with a large volume. BRIEF DESCRIPTION OF THE DRAWINGS
