Description

Technical Field

[0001] The present invention relates to an obstacle-breaking fire-fighting device, in particular to an obstacle-breaking fire-fighting device based on high-voltage pulse discharge technology, and belongs to the field of obstacle-breaking fire-fighting. Background Art

[0002] Pulse power technology is an electrophysical technology that studies the use of high-power pulse generators to slowly store energy, then transform, compress and regulate it, and finally release it to the load in an extremely short pulse. In essence, it compresses energy on a time scale to obtain a high peak power output in an extremely short time, so that the energy density per unit volume is very high. Based on this technology, high-power pulses have been applied to crush hard rocks and plain concrete at home and abroad with good results. And after exploration and research, it took only 20 years for the world to increase the pulse power from 1012W to 1014W, and a series of related quasi-industrial equipment has been developed. This technology is booming, and its current development direction is to increase power levels and explore diversified applications.

[0003] In modern cities, fires frequently occur, causing huge economic losses to human life and property. After a fire occurs, timely and effective firefighting can minimize the losses. Therefore, the improvement and optimization of firefighting equipment is of great significance for firefighting. After a fire occurs in a modern building, the fire source is blocked by obstacles such as walls. Firefighters need to clear the walls and other obstacles first and cannot directly deal with the fire source, which may delay the golden rescue time and increase unnecessary injuries and losses.

[0004] At present, firefighters mainly use demolition to remove obstacles before extinguishing the fire. Mechanical demolition is generally used to demolish walls and buildings, that is, to clear obstacles by mechanical means. Mechanical crushing of rocks and concrete is to use mechanical drive to directly contact the crushed objects and use external compressive stress to crush rocks and concrete. The crushing process has the disadvantages of easy wear of props, high energy consumption, low efficiency, and low safety, which directly prolongs the time of fire fighting and rescue. Summary of the invention

[0005] The purpose of the present invention is to solve the problems existing in the prior art and to provide an obstacle-breaking fire-fighting equipment based on high-voltage pulse discharge technology, which applies pulse power technology to obstacle-breaking fire-fighting and integrates a water spraying mechanism to achieve the purpose of extinguishing fires while breaking down obstacles such as walls, thereby achieving high efficiency and high safety in the fire-fighting process.

[0006] In order to achieve the above technical objectives, the present invention adopts the following technical solutions:

[0011] Compared with the prior art, the present invention has the following beneficial effects:

During the process of breaking down the wall, the pressure of the water inlet can be increased so that the fire-fighting water can be sprayed out from the water spray opening to extinguish the fire.

What is disclosed is only a preferred specific implementation of the present invention, and it is certainly not intended to limit the scope of the present invention. Therefore, equivalent changes made according to the claims of the present invention are still within the scope covered by the present invention.

[0019] See Figure 1 As shown, the present invention discloses an obstacle-breaking fire-fighting equipment based on high-voltage pulse discharge technology, comprising an electrode main body tube 10; the electrode main body tube 10 is a hollow tubular stainless steel structure; one end of the electrode main body tube 10 is conically closed, and the conical surface is provided with two rows of evenly distributed water spraying openings 8; the other end of the electrode main body tube 10 is sealed and welded with a connecting flange 11, and four through holes 12 are provided near the connecting flange; Figure 3 As shown, two high-voltage electrode assemblies 1 and two grounding electrode assemblies 2 are welded on the outer surface of the conical closed end of the electrode main body tube 10, and the two high-voltage electrode assemblies 1 and the two grounding electrode assemblies 2 are arranged opposite to each other, and the high-voltage electrode assembly 1 and the grounding electrode assembly 2 are arranged at 90 degrees to each other; the connecting flange 11 is sealed and connected to the insulating basin 7 by bolts through the connecting ring 5; a shell 3 is provided between the insulating basin 7 and the electrode main body tube 10; one end of the shell 3 is sealed and sleeved on the electrode main body tube 10, and the other end is sealed and connected to the insulating basin 7 to form a closed space, in which insulating liquid is stored, and the through hole 12 on the electrode main body tube 10 is arranged in the closed space; the outer surface of the electrode main body tube 10 is tightly wrapped with an insulator 4; the two ends of the insulator 4 are fastened and crimped by a sealing ring 13; the insulating basin 7 is provided with a connecting terminal 9; the shell 3 is provided with a fire-fighting water gun connector 6;

[0020] See Figure 2 As shown, each of the high-voltage electrode assemblies 1 includes a connecting plate 14 welded to the electrode main body tube 10 at one end and an electrode pin 15 connected to the other end of the connecting plate 14; the electrode pin 15 is a triangular plate, which makes the discharge effect better and more uniform;

[0021] The insulating basin 7 is made of epoxy resin;

[0022] The insulator 4 is made of nylon or polytetrafluoroethylene and plays an insulating role.

[0023] The working process is:

[0024] The two high-voltage electrode assemblies 1 and the two grounding electrode assemblies 2 are in direct contact with the wall, and the connecting terminal 9 is connected to the high-voltage pulse generator. The high-voltage pulse directly acts on the wall, forming a discharge channel inside the wall, and utilizing the tensile stress inside the wall to break the wall. During the entire action process, the insulating liquid is discharged from the water spray opening 8, which can flush away the debris generated in the crushing process. The residues generated in the process of breaking the wall vary in size. If the residue is small in size, it can be directly flushed away by the insulating liquid sprayed from the water spray opening 8, while larger residues can continue to be broken into small-sized debris, which are finally flushed away by the insulating liquid.

[0025] The present invention utilizes pulse power technology to break up obstacles such as walls, which can greatly improve the efficiency of fire rescue. At the same time, the obstacle-breaking fire-fighting equipment can also be connected to the fire-fighting water gun through the fire-fighting water gun connector 6. In the process of breaking down the wall, the pressure of the water inlet can be increased so that the fire-fighting water can be sprayed out from the water spray opening 8 to extinguish the fire, thereby improving the fire-fighting efficiency and providing space for rescue work.

[0026] While specific implementations of the present invention have been shown and described, it will be appreciated by those skilled in the art that numerous changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
