Description

Technical Field

[0001] This invention relates to the field of fire rescue demolition equipment technology, specifically to an auxiliary device for demolition and rescue in confined spaces during a fire. Background Technology

[0002] In various fire rescue scenarios such as building fires and collapse fires, a large number of trapped people are often in narrow or semi-enclosed spaces such as corridor gaps, wall cracks, narrow gaps between doors and windows, and small cavities blocked by furniture. These spaces are characterized by small size, dense obstacles, high smoke concentration, low visibility, and poor structural stability, making them key and difficult areas for fire rescue.

[0003] Firefighters primarily use three types of breaching tools: manual mechanical breaching tools, internal combustion breaching tools, and electro-hydraulic breaching tools. However, currently, firefighters mainly use manual mechanical breaching tools, including conventional tools such as fire axes, crowbars, and breaching hammers, during fire rescue operations. The main reason is the high temperature at fire scenes. Internal combustion breaching tools require gasoline as fuel, which is flammable and poses a significant danger if brought into a fire. Electro-hydraulic breaching tools require batteries for use in fire scenes, but existing batteries lack high-temperature protection. If these batteries are introduced into a fire without protection, they can easily spontaneously combust due to the high temperatures, exacerbating the fire situation. To avoid this problem, firefighters are forced to use traditional manual mechanical breaching tools. However, in actual rescue operations, the use of traditional manual mechanical demolition tools has many obvious drawbacks. First, traditional manual mechanical demolition tools have a simple structure and cannot efficiently and quickly demolish objects. However, fire rescue is time-sensitive and requires rapid demolition, which traditional demolition tools cannot meet. Second, in extremely confined spaces such as low cavities in fire scenes, rescuers cannot carry demolition tools to work deep inside. They can only conduct exploratory demolition from the outside, which limits the demolition range, creates many blind spots, and makes it difficult to quickly open up life-saving channels.

[0004] In summary, traditional manual mechanical demolition tools are insufficient for efficient demolition operations in fire scenes, while internal combustion demolition tools require gasoline, which poses too high a risk in fire situations and is also unsuitable. Only electric hydraulic demolition tools can efficiently complete demolition operations. However, existing electric hydraulic demolition tools lack high-temperature resistant power supplies. Therefore, there is an urgent need in the market for an electric demolition and rescue auxiliary device that is equipped with a fire-resistant power supply and can be used in confined spaces to solve the above problems.

Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0022] The following description, in conjunction with the accompanying drawings and specific embodiments, provides further details: Example 1

[0023] like Figure 1 , Figure 2 and Figure 6As shown, this embodiment provides an auxiliary device for demolition and rescue in confined spaces during a fire. The core protective structure of the entire device includes two main components: a flame-retardant shell 1 and a flame-retardant cover plate 3. The flame-retardant shell 1 has an integrally formed hollow mounting cavity 11, inside which a battery 2 can be detachably placed. The battery 2 is electrically connected to the flame-retardant shell 1 through an electrical connection structure. The flame-retardant cover plate 3 is integrally sealed and assembled at the opening on the front of the flame-retardant shell 1. The two together form a complete and sealed protective shell. The flame-retardant outer shell 1 and the flame-retardant cover plate 3 adopt a five-layer composite protective structure, which consists of a high-temperature resistant flame-retardant protective layer 33, a heat insulation layer 34, a phase change heat absorption cavity 35, an insulation layer 36, and a buffer layer 37 from the outside to the inside. The phase change heat absorption cavity 35 is filled with a phase change heat absorption material. The high-temperature resistant flame-retardant protective layer 33 is made of stainless steel perforated plate laminated with flame-retardant fiberglass ceramic cloth. The heat insulation layer 34 is made of silica aerogel felt. The phase change heat absorption cavity 35 is filled with expanded graphite-based flame-retardant paraffin as a phase change heat absorption material. The insulation layer 36 is made of mica board cut and processed. The buffer layer 37 is made of flame-retardant silicone pad. The multi-layer composite structure can simultaneously achieve multiple effects of fireproofing, heat insulation, heat absorption, insulation and buffer protection.

[0024] like Figure 2 , Figure 3 and Figure 5 As shown, a power connector 12 is fixedly installed on the top of the inner side of the mounting cavity 11 of the flame-retardant housing 1. Multiple sets of connecting grooves 13 are evenly opened along the edge of the opening on the front of the flame-retardant housing 1. A first connecting male head 14 is fixedly assembled on the side of the flame-retardant housing 1. A pair of shoulder straps 17 are provided on the top of the back of the flame-retardant housing 1. Each shoulder strap 17 is equipped with a D-ring buckle 18 at the bottom. A pair of adjustment straps 19 are arranged at the bottom of the back of the flame-retardant housing 1. The ends of all adjustment straps 19 can be fastened to the D-ring buckle 18. Rescue personnel can carry the entire power protection housing on their bodies through the shoulder straps 17. The tightness of the shoulder straps 17 can be adjusted by the adjustment straps 19 and the D-ring buckle 18, making it suitable for operators of different body shapes. Both the flame-retardant outer shell 1 and the flame-retardant cover plate 3 have separate injection ports 16 on their tops. Each injection port 16 is connected to the internal space of the phase change heat absorption chamber 35 at the corresponding position. Each injection port 16 is equipped with a plug 15. The bottom end of the plug 15 is integrally formed with a sealing stud 151. The sealing stud 151 is sealed and assembled inside the injection port 16 by a threaded connection. The operator can unscrew the plug 15 and add phase change heat absorption material into the phase change heat absorption chamber 35 through the injection port 16. After replenishment, tighten the plug 15 again to maintain the sealing state of the chamber.

[0025] like Figure 4 and Figure 5As shown, the battery 2 has grooves 21 at both the top and bottom of its front side. Each groove 21 is fitted with a pull rod 22, which allows the battery 2 to be quickly pulled out of the mounting cavity 11 for disassembly and maintenance. A power connector 23 is fixedly installed at the top of the end of the battery 2 that is inserted into the mounting cavity 11. A power connector slot 24 is provided at the position of the power connector 23 corresponding to the position of the power plug 12. After the battery 2 is fully pushed into the mounting cavity 11, the power connector slot 24 can accurately connect to the power plug 12 to quickly complete the circuit conduction. The outer edge of the flame-retardant cover 3 is integrally formed with a connecting edge 31. The connecting edge 31 has connecting holes 32 at the positions of each connecting groove 13. The sealing gasket is completely pasted on the mating surface of the connecting edge 31 facing the flame-retardant shell 1. During assembly, the sealing gasket is attached to the open end face of the flame-retardant shell 1, and then bolts are used to pass through the connecting holes 32 and lock it onto the flame-retardant shell 1. The sealing gasket eliminates assembly gaps and ensures a sealed and heat-insulating environment inside the mounting cavity 11.

[0026] like Figure 1 , Figure 2 , Figure 7 and Figure 8 As shown, the first male connector 14 on the side of the flame-retardant housing 1 connects to the grip handle 4 via a flame-retardant cable 41. The end of the flame-retardant cable 41 away from the flame-retardant housing 1 is fitted with a first female connector 42. After the first female connector 42 and the first male connector 14 are plugged in, the entire machine's circuit is connected. Multiple sets of control switches 43 are arranged on the surface of the grip handle 4. All control switches 43 can control the start and stop of the electric hydraulic demolition tool 7, and the expansion, cutting, and clamping actions of the pliers 71, allowing the operator to easily control the equipment's operating status with one hand. The end of the grip handle 4 away from the flame-retardant cable 41 has an integrally formed hollow support rod 44. A spring wire 45 runs through the support rod 44. One end of the spring wire 45 is connected to the internal circuit of the grip handle 4, and the other end extends out of the support rod 44 and is fitted with a second female connector 46. The support rod 44 is externally fitted with a connecting rod 5. The connecting rod 5 can slide back and forth along the axial direction of the support rod 44 to achieve overall length extension and retraction. A clamping knob 51 is installed on the side wall of the connecting rod 5 near the handle 4. After adjusting the extended length of the connecting rod 5, tightening the clamping knob 51 will lock the relative position of the connecting rod 5 and the support rod 44, thereby changing the overall length of the entire operating rod to adapt to different depths and narrow working spaces. A first flange 52 is fixedly installed at the end of the connecting rod 5 away from the handle 4. Multiple sets of first flange holes 53 are circumferentially formed on the edge of the first flange 52.

[0027] like Figure 1 and Figure 9As shown, a flame-retardant junction box 6 is assembled at the front end of the socket rod 5 via a flange structure. A second male connector 61 is fixedly installed at the end of the flame-retardant junction box 6 facing the socket rod 5. The second male connector 61 can be plugged into the second female connector 46 extending inside the support rod 44 to conduct electrical circuit. A second flange 62 is integrally formed on the end face of the flame-retardant junction box 6 with the second male connector 61. Multiple sets of second flange holes 63 are opened on the edge of the second flange 62. During assembly, the second flange 62 is completely fitted against the end face of the first flange 52, and bolts are used to simultaneously pass through the first flange holes 53 and the second flange holes 63 to lock and fix it, realizing a stable connection between the flame-retardant junction box 6 and the socket rod 5. A threaded connector 68 is fixedly installed at the end of the flame-retardant junction box 6 away from the second male connector 61. A connecting slot 69 is opened at the center of the threaded connector 68 for transmitting power.

[0028] like Figure 1 and Figure 10 As shown, the front end of the flame-retardant junction box 6 is connected to the electric hydraulic demolition tool 7 via a threaded connector 68. The electric hydraulic demolition tool 7 rotates to assemble the threaded connector cap 76 at one end facing the flame-retardant junction box 6. A connecting plug 77 is provided at the center of the inner side of the threaded connector cap 76. During assembly, the connecting plug 77 is inserted into the connecting slot 69 to complete the circuit connection. Then, the threaded connector cap 76 and the threaded connector 68 are tightened to achieve a sealed electrical connection between the electric hydraulic demolition tool 7 and the flame-retardant junction box 6. The electric hydraulic demolition tool 7 has two sets of clamp heads 71 ​​hinged at one end away from the threaded connector 76. The cutting part 72 is integrally formed in the middle of the two sets of clamp heads 71. The outer end of the clamp head 71 is provided with an expansion part 73. The inner end of the two sets of clamp heads 71 ​​is provided with a clamping part 74. One set of clamp heads 71 ​​integrates three demolition functions: cutting, expansion and clamping. The electric hydraulic demolition tool 7 is equipped with a hydraulic oil pump 75 inside the body. The hydraulic oil pump 75 can drive the built-in hydraulic cylinder to reciprocate, thereby driving the two sets of clamp heads 71 ​​to complete the opening and closing action, and carry out demolition operations for different obstacles in the fire scene.

[0029] Example 2

[0030] like Figure 1 , Figure 9 and Figure 11As shown, the difference between this embodiment and embodiment 1 is that the complete set of equipment is also equipped with a lighting lamp 8 to assist in operation in confined spaces. A third connecting male 64 is fixedly mounted on the side wall of the flame-retardant junction box 6, and a connecting rod 65 is fixedly extended outward from the side wall. The end of the connecting rod 65 is integrally formed with a mounting connector 66, and a through threaded hole 67 is opened in the center of the mounting connector 66. A lighting switch 81 is independently arranged on the side of the lighting lamp 8. The end of the lighting lamp 8 facing the mounting connector 66 is integrally formed with a mounting stud 82. The mounting stud 82 is fixed inside the threaded hole 67 by threaded connection, so that the lighting lamp 8 can be detached and assembled. A wire 83 is threaded through the stud 82. After the end of the wire 83 extends out, a third female connector 84 is attached. The third female connector 84 is plugged into the third male connector 64, so that the battery 2 can supply power to the lighting lamp 8. The operator can control the lighting lamp 8 to turn on and off independently through the lighting switch 81. When the electric hydraulic demolition tool 7 is inserted into a narrow crevice with dense smoke and extremely low visibility, the lighting lamp 8 can simultaneously illuminate the front demolition point, clearly observe the obstacle structure, and improve the accuracy of demolition operations in narrow spaces.

[0031] Working principle: This solution relies on a backpack-type multi-layer composite protective power carrier to provide power. Before operation, rescuers use the shoulder straps 17, adjustment straps 19, and D-ring buckles 18 to carry the protective shell, which is composed of a flame-retardant outer shell 1 and a flame-retardant cover plate 3, on their backs. By unscrewing the filling port 16 and the sealing plug 15, phase change heat-absorbing material can be added as needed. The five-layer composite protective structure of the shell simultaneously achieves fireproofing, heat insulation, heat absorption, insulation, and buffer protection. The battery 2 inside the shell can be quickly installed and removed via the pull rod 22. After being pushed into the installation cavity 11, the power supply connector 23 connects to... The power plug 12 is precisely connected to complete the basic circuit conduction; the current is transmitted to the grip handle 4 through the first male connector 14 on the side of the flame-retardant shell 1 and the flame-retardant cable 41. The operator controls the start and stop of the electric hydraulic demolition tool 7 and the expansion, cutting, and clamping actions of the pliers 71 through the control switch 43 on the handle surface. The spring wire 45 inside the grip handle 4 passes through the telescopic sleeve rod 5. The telescopic length of the sleeve rod 5 is locked by the clamping knob 51 to adapt to different depths and narrow working spaces. The second female connector 46 at the end of the spring wire 45 connects to the flame-retardant cable. The second male connector 61 of the box 6 is plugged into the conductive circuit. The flame-retardant junction box 6 is securely connected to the connecting sleeve 5 through the flange structure at both ends. The front threaded connector 68, in conjunction with the threaded connector cap 76, allows the connecting plug 77 to mate with the connecting slot 69, thus powering the electric hydraulic demolition device 7. The device's built-in hydraulic oil pump 75 drives the hydraulic cylinder to drive the double-headed clamp 71, which integrates shearing, expansion, and clamping functions, to complete the demolition of various obstacles in the fire scene. At the same time, the side wall of the flame-retardant junction box 6 can be detachably equipped with a lighting lamp 8 through the connecting rod 65 and threaded structure. The lighting lamp 8 contains... The conductor 83 is connected to the third female connector 84 and the third male connector 64 on the side wall of the junction box for power supply. The operator can control the lighting switch 81 independently to illuminate the demolition point in a confined space with heavy smoke and poor visibility. The entire set of equipment relies on modular plug-in circuits to achieve graded power transmission. The multi-layer flame-retardant and heat-insulating protective structure ensures power supply safety in the high-temperature environment of the fire scene. The telescopic operating rod, multi-functional demolition pliers 71, and matching lighting device work together to adapt to various narrow and confined scenarios in the fire scene to carry out safe and precise demolition and rescue operations.
