Technical Field

[0001] The utility model relates to the technical field of blasting equipment, in particular to a hydrogen-oxygen blasting device. Background Technique

[0002] As a scientific technology, blasting is widely used. However, its application in engineering is undoubtedly the most important and common. In mining and mountain opening, drill and blast methods are used to excavate tunnels for building railways and highways. It is also used in some water conservancy projects and in cities for demolishing buildings. Rock blasting refers to the blasting operation aimed at breaking and throwing rocks, such as mine exploitation blasting, roadbed excavation blasting, and roadway (tunnel) driving blasting.

[0003] The huge energy generated by the explosion of explosives is used to destroy the original structure of an object. This "destruction" effect cannot be replaced by other methods. Although it does not independently complete a project, it is an important process. Especially in projects such as rock excavation and mine exploitation, this process is indispensable. The main steps of rock blasting operation are to drill blast holes in the medium to be blasted, or excavate a medicine chamber, or lay explosives on its surface, put in a detonating detonator, and then detonate.

[0004] However, when using explosives for rock breaking, on the one hand, there are safety risks in the transportation and storage of explosives. On the other hand, the production and use of explosives will generate a large amount of carbon emissions. Content of the Utility Model

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0044] The following Figure 1 and Figure 2 will further introduce the present utility model in detail.

[0045] Blasting, as a scientific and technological method, has a wide range of applications. However, its application in engineering is undoubtedly the most important and common. In mining and mountain opening, drill and blast methods are used to excavate tunnels for building railways and highways. It is also used in some water conservancy projects and in cities for demolishing buildings. Geotechnical blasting refers to blasting operations aimed at crushing and throwing geotechnical materials, such as mine opening blasting, roadbed excavation blasting, and roadway (tunnel) driving blasting.

[0046] Using the huge energy generated by explosive blasting to destroy the original structure of a certain object, this "destruction" effect cannot be replaced by other methods. Although it does not independently complete a project, it is an important process. Especially in projects such as rock excavation and mine mining, this process is indispensable. The main steps of geotechnical blasting operations are to drill blast holes in the medium to be blasted, or excavate a blasting chamber, or lay explosives on its surface, place the detonator, and then detonate.

[0047] However, when using explosives for rock fragmentation, on the one hand, there are safety risks in the transportation and storage of explosives, and on the other hand, the production and use of explosives will generate a large amount of carbon emissions.

[0048] Based on the above technical problems, the applicant has the following technical solution concept:

The hydrogen burns rapidly in oxygen to produce an explosion, completing the blasting and achieving rock fragmentation. Hydrogen can be prepared by electrolyzing water, so hydrogen can be prepared on-site during blasting. Therefore, hydrogen does not need to be transported over long distances and stored for a long time, reducing the safety risk. On the other hand, the explosion of hydrogen only produces water, which can reduce carbon emissions and protect the environment.

By using the dividing piece 5 to divide the interior of the blasting tube 1 into two parts, hydrogen and oxygen are separated. During blasting, move the opening rod 6 to make the dividing piece 5 deformed or damaged, so that the spaces on both sides of the dividing piece 5 are connected, and hydrogen and oxygen can be mixed. Then, ignite through the detonating head 4 to avoid the combustion and explosion of oxygen and hydrogen before blasting and prevent dangerous accidents from occurring.

The first booster pump 12 inputs the hydrogen in the hydrogen cylinder 11 into the bursting tube 1 and pressurizes the hydrogen, and the second booster pump 14 inputs the oxygen in the oxygen cylinder 13 into the bursting tube 1 and pressurizes the oxygen, thereby increasing the pressure of the oxygen and hydrogen in the bursting tube 1 and increasing the power of the explosion.

[0055] Specifically, it also includes: a first end cover 7, which is arranged at the opening of one end of the blasting tube 1, and is detachably connected to the blasting tube 1, and is used to open or seal the end opening of the blasting tube 1. A second end cover 8, which is arranged at the opening of the other end of the blasting tube 1, and is detachably connected to the blasting tube 1, and is used to open or seal the end opening of the blasting tube 1.

Under the pressure of the first end cover 7 and the second end cover 8, the first positioning tube 9, the second positioning tube 10 and the split piece 5 are positioned to complete the assembly of the blasting tube 1.
