[0021] In order to make the objectives, technical solutions and advantages of the present invention more clear and explicit, the present invention is further described in detail below with reference to the accompanying drawings and examples.

[0022] like Figure 1-6 As shown, the present invention discloses a novel gas explosion blasting device, which comprises: a bottom cover 1, a tube 2, an upper cover 3 and an initiation excitation structure 4, wherein the upper cover 3 and the bottom cover 1 respectively block the two ends of the tube 2; one or more cut-out holes 20 are provided on the side of the tube 2, and a tempered glass 5 is adhered to the position corresponding to the cut-out hole 20 in the tube 2; the bottom cover 1, the tube 2, the tempered glass 5 and the upper cover 3 form a sealed space 7; the upper cover 3 is also connected with a one-way air intake valve 6, which is connected to the sealed space 7, so that the sealed space can be inflated through the one-way air intake valve so that the sealed space reaches the air pressure set for blasting; a pre-explosion hole 50 is provided at the end corner edge of the tempered glass 5, and the initiation excitation tube of the initiation excitation structure 4 is built in the pre-explosion hole 50, and the initiation excitation structure 4 detonates the initiation excitation tube so that the tempered glass 5 is broken, and the high-pressure gas filled in the sealed space 7 rushes out instantly, thereby achieving the effect of blasting.

[0023] Preferably, the number of the cut holes 20 can be one, two, three, four, five or six.

[0024] After adopting the above structure, the present invention adopts the bobbin as a reusable material and the tempered glass as a disposable material for releasing high-pressure gas, so the detonation excitation structure is installed in the pre-explosion hole set in the tempered glass, and the detonation is detonated by stimulating the detonation excitation structure, so that the tempered glass is broken, and the high-pressure gas filled in the sealed space rushes out instantly, thereby achieving the effect of blasting; and the upper cover and the bottom cover are used as the packaging bobbin, the overall structure is simple, and only the tempered glass needs to be replaced after each blasting, and it can be reused, which can reduce the cost of gas explosion. In addition, the manufacturing cost of the gas explosion blasting device completely changes the traditional method of detonating by heating, so the overall structure is simpler and the manufacturing cost is lower.

[0025] Specifically, the detonation excitation structure 4 includes: a detonation wire 8, a plug 9, a detonation excitation tube 10 and a detonation connector 11. The plug 9 is built into the pre-explosion hole 50 as a plug, and the detonation excitation tube 10 is inserted into the pre-explosion hole 50 and fixed, and there is a certain distance between the detonation excitation tube 10 and the plug 9; the detonation connector 11 is installed on the upper cover 3, and the detonation connector 11 is connected to the detonation excitation tube 10 through the detonation wire 8.

[0026] The present invention can seal the pre-explosion hole by embedding the plug in the pre-explosion hole. When the detonation excitation tube is excited, a strong impact is instantly generated after the detonation excitation tube is detonated. Since there is a certain distance between the detonation excitation tube and the plug, the generated impact can cause the tempered glass to break, thereby causing the high-pressure gas in the sealed space in the barrel to rush out instantly, thereby achieving the effect of gas explosion.

[0027] Specifically, the detonating wire 8 is connected to the detonating excitation tube 10 via a detonating joint 12 .

[0028] Specifically, the thickness of the tempered glass 5 is 3-40 mm. The tempered glass of such thickness can be quickly cracked by the set high-pressure gas impact, and it is also convenient for the detonation excitation structure to achieve edge fragmentation, providing a basis for the initial fragmentation of the tempered glass.

[0029] Specifically, the diameter of the pre-explosion hole 50 is 1-20 mm, and the edge distance of the pre-explosion hole 50 is less than the thickness of the tempered glass. The pre-explosion hole with a diameter of 1-20 mm is more convenient for the detonation excitation tube to achieve the edge angle of the broken tempered glass.

[0030] Specifically, the tempered glass is bonded and fixed to the tube by glass glue, and the tempered glass is bonded and fixed to the copper tube by glass glue, so it is convenient to replace the tempered glass and reuse the tube, and at the same time, the manufacturing process is simplified and the cost is reduced.

[0031] Specifically, it also includes an upper ring 13, and the upper cover 3 is fixed to the upper end of the barrel 2 through the upper ring 13. The upper cover 3 is also provided with a positioning hole 14 for convenient screwing and clamping and a lifting ring 15 for convenient lifting; the positioning hole is provided to facilitate the rotation, tightening and loosening of the upper cover; and the lifting ring is for the convenience of lifting the new gas explosion blasting device.

[0032] Specifically, the inner part of the upper ring 13 is provided with an internal thread, and the upper cover 3 is correspondingly provided with an external thread, and the upper cover 3 and the upper ring 13 are connected and fixed by the external thread and the internal thread; and the upper cover 3 is also provided with at least one sealing rubber ring 16; because the upper cover 3 is provided with the sealing ring 16, the upper cover and the upper ring can be sealed after being connected.

[0033] Specifically, the upper cover is also equipped with a temperature sensor 17 for detecting the temperature of the gas in the sealed space and an air pressure sensor 18 for detecting the air pressure in the sealed space. Since the temperature of the gas is different, the air pressure is also affected, so it is necessary to detect the gas temperature in the sealed space through a temperature sensor, and detect the air pressure in the sealed space through an air pressure sensor, and feed back to the detonation controller. After detecting that the temperature and air pressure reach the set detonation parameters, the detonation controller controls the detonation excitation structure to blast.

[0034] Specifically, the outer diameter of the bobbin 2 is 40-400 mm, and the length of the bobbin 2 is 300-2000 mm; the two ends of the bobbin 2 are connected to the upper collar 13 and the bottom cover 1 by bonding or welding.

[0035] In actual production, the upper sleeve ring, the bobbin and the bottom cover can be made of polymer materials and metal materials.

[0036] Production process: Solution 1: The upper ring, bottom cover and bobbin are all made of polymer materials, and the upper ring, bottom cover and bobbin are bonded with glue or ultrasonically welded.

[0037] Solution 2: The upper collar, bottom cover and bobbin are all made of metal materials, and the upper collar, bottom cover and bobbin are connected by electric welding.

[0038] Solution 3: The bobbin is made of metal material, and the upper ring and bottom cover are made of polymer material (plastic); the upper ring and the bobbin are connected by threads and super glue (that is, after the threads are coated with glue, they are rotated and tightened, and after the glue dries, it not only seals but also strengthens the connection), and the bottom cover and the bobbin are bonded by glue.

[0039] The present invention adopts a detonation excitation tube to be pre-buried in the pre-explosion hole of the tempered glass, and then after the air pressure and temperature in the sealed space reach the set detonation parameters, the detonation excitation tube is excited to burst the edge corners of the tempered glass, and then under the action of the high-pressure gas in the sealed space, the rest of the tempered glass continues to shatter, so that the high-pressure gas can rush out instantly, thereby achieving the effect of gas explosion; the gas explosion starting method and principle adopted by this gas explosion device are obviously different from the existing gas explosion starting method and principle; the existing gas explosion device is to heat the gas in the detonation tube by a heating tube built into the gas explosion tube to reach the gas pressure of the gas explosion; so the existing gas explosion device has a more complicated structure, and the gas explosion tube is disposable, so the gas explosion cost is high, and the gas explosion tube cannot be reused. In contrast, the overall structure of the present invention is simple, the manufacturing cost is low, and it can be reused, and only the tempered glass needs to be replaced.

[0040] The above are only preferred implementation modes of the present invention, which certainly cannot be used to limit the scope of rights of the present invention. It should be pointed out that for technicians in this technical field, any modification or equivalent replacement of the technical solution of the present invention without creative work does not depart from the protection scope of the technical solution of the present invention.
