[0002] In various natural disasters and man-made accidents, trapped people are often located in complex structural environments, such as inside collapsed buildings or in small spaces. One of the main challenges facing rescue work is how to quickly and safely reach the location of the trapped people and provide timely rescue. For example, in a fire scene or an accident where part of a building collapses, it is necessary to quickly find the location of the trapped people and quickly open rescue and escape passages. During rescue, it is required to be able to accurately detect the trapped people and cut out suitable passages for the building structures around the trapped people. Existing rescue equipment is usually single-function. For example, a cutting device can only perform cutting operations but cannot provide life detection information. Different rescue equipment needs to be carried and operated separately, which is not convenient for coordinated operation, increasing the burden on the rescue team and reducing the rescue efficiency. In addition, the shock waves generated by conventional explosives can easily affect surrounding buildings, making rescue difficult. Summary of the invention

For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0024] Example 1

[0025] like Figure 1-Figure 3As shown, the present invention provides an emergency rescue energy-gathering cutting device with a life detection function, comprising a life detection device 6 and an energy-gathering cutting device body, wherein the energy-gathering cutting device body is a ring-shaped hollow structure in the middle, and the life detection device 6 is arranged on the inner side or the outer side of the energy-gathering cutting device body, wherein the life detection device 6 is an acoustic wave life detector or a radar life detector, wherein the acoustic wave life detector captures the acoustic waves or vibration signals generated by heartbeat, breathing, sound (such as cries for help, knocking sounds), etc.; the radar life detector uses radar waves to detect the existence of life forms, and determines the position of life forms by analyzing the reflected signals, and can detect the position of life forms in the event of a fire or a house collapse.

[0026] The body of the shaped energy cutting device includes a protective cover 2, a shaped energy cutting rope 3 and a fuze system. A groove is provided on the front side of the protective cover 2. The shaped energy cutting rope 3 is embedded in the groove on the front side of the protective cover 2. The protective cover 2 plays a protective role and has the functions of absorbing shock waves and blocking the scattering of explosion products; the shaped energy cutting rope 3 includes a protective sleeve 301, explosives 302 and a charge cap 303. One side of the protective sleeve 301 is a closed structure and the other side is an open structure. Grooves are symmetrically opened on the inner wall of the open end of the protective sleeve 301. The two ends of the charge cap 303 are respectively clamped in the two grooves, and the explosive 302 is arranged between the charge cap 303 and the protective sleeve 301.

[0027] The cross section of the medicine liner 303 is a conical structure, and the top of the conical structure adopts a hemispherical transition structure. The medicine liner 303 in this embodiment is a multi-layer composite medicine liner 303, which includes an outer layer cover with a thickness of 0.5 mm, an intermediate layer cover with a thickness of 1 mm, and an inner layer cover with a thickness of 1.5 mm. Each layer is connected by laser welding. The intermediate layer cover is located between the inner layer and the outer layer, which plays a transition role and improves the stability of the jet; the outer layer cover is located at the outermost side to form a jet head and improve the initial velocity of the jet. The outer layer cover is usually made of materials with low density and good plasticity, such as aluminum, magnesium alloy, etc. These materials can form a stable jet head and help to improve the initial velocity of the jet; the intermediate layer cover material: can choose a material with moderate density and good plasticity, such as copper or copper alloy, which helps to improve the overall quality and stability of the jet; the inner layer material: use high-density materials, such as tungsten alloy, tantalum, etc., to increase the penetration of the jet; the density of each layer of material gradually increases along the thickness direction, so that the medicine liner 303 forms a gradient material structure. The inner cover is in close contact with the explosive 302 and is responsible for converting the explosion energy into a high-speed jet. When the explosive 302 is detonated, the energy generated by the explosion first acts on the inner cover, causing the inner cover to deform rapidly and form a high-speed jet. The middle cover and the outer cover then participate in the jet formation process and act on the jet together through their respective characteristics to improve the jet's speed, stability and penetration.

[0028] The protective sleeve 301 in this embodiment can be set to a double-layer structure, with the outer layer using a high-density polymer, such as polyurethane or polycarbonate, which has good energy absorption and flame retardancy; the inner layer is an elastic layer, using rubber or special composite materials to increase the elasticity of the protective sleeve 301 to better absorb explosion energy.

[0029] The detonating end of the fuze system passes through the rear side of the protective cover 2 to the inside of the protective cover 2 and is connected to the energy-forming cutting rope 3. The fuze system includes a detonator and an electronic detonator. The detonator is connected to the electronic detonator through a detonating cable. One end of the electronic detonator passes through the inside of the protective cover 301 and contacts the explosive 302.

[0030] The device also includes a support frame, which includes a frame 1 and a retractable support rod 5. The life detection device 6 is arranged on the inner side of the frame 1. The support rod 5 has diagonal support rods 7 symmetrically hinged on both sides to improve the stability of the entire device when it is fixed. The support rod 5 is hinged to the frame 1, and each corner on the outside of the frame 1 is provided with a clamping angle plate 4 for installing the protective cover 2.

[0031] Example 2

[0032] like Figure 4 As shown, the difference between this embodiment and embodiment 1 is that the outer cover and the middle cover are porous structures, that is, the outer cover and the middle cover are both provided with jet holes 8, which can be specifically designed as follows: the porosity of the outer cover is 20%, the porosity of the middle cover is 10%, the pore size of the outer cover is 0.5 mm, and the pore size of the middle cover is 0.3 mm. The use of a porous structure in the outer cover or the middle cover can reduce the amount of material used and reduce the weight of the medicine liner 303, and at the same time control the formation of the jet by changing the pore structure.

[0033] Example 3

[0034] The difference between this embodiment and the embodiments 1 and 2 is that: in the medicine-shaped liner 303, micro grooves or micro pore structures of micrometer or nanometer scale are evenly arranged on the surface of the outer cover, and the specific design and layout are: the micro groove width is 20 micrometers, the micro groove depth is 10 micrometers, and the micro groove spacing is 30 micrometers. This can improve the stability of the jet and reduce the dispersion of the jet.

[0035] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
