[0019] The present invention will be further described in detail below with reference to the accompanying drawings.

[0020] like Figure 1As shown, a remote blasting operation system includes a gas storage mechanism 1, a gas blasting head 2, and a remote control system 3.

[0021] like Figure 1 , Figure 2 As shown, the gas storage mechanism 1 is used to connect to the air compressor and store compressed air, and the gas rupture head 2 is used to extend into the borehole at the rupture location. The remote control system 3 includes a valve box 31 and a control box 32. The air inlet of the valve box 31 is connected to the gas storage mechanism 1 through a gas supply hose 33, and the air outlet is connected to the gas rupture head 2 through a rupture hose 34. The control box 32 is electrically connected to the valve box 31.

[0022] like Figure 1 , Figure 2 As shown, the valve box 31 is equipped with an air inlet main pipe 311 and multiple air outlet branch pipes 312. The air inlet main pipe 311 is connected to the air supply hose 33, and the air outlet branch pipes 312 are connected to the burst hose 34. Each air outlet branch pipe 312 is equipped with a solenoid valve 313. One of the air outlet branch pipes 312 is equipped with a pressure relief pipe 314, and a pressure relief valve 315 is installed on the pressure relief pipe 314.

[0023] like Figure 1 , Figure 2 As shown, the control box 32 contains a controller 321, a power bank 322, and a remote controller 323. The controller 321 is connected to the solenoid valve 313, the power bank 322 is connected to the controller 321 and the solenoid valve 313, and the remote controller 323 is communicatively connected to the controller 321 and controls the opening and closing of the solenoid valve 313.

[0024] When blasting operations are required, high-pressure air is first supplied by an air compressor and stored in the gas storage unit 1. Then, the gas storage unit 1 is transported to the work site. Subsequently, the main air inlet pipe 311 and the gas storage unit 1 are connected by the air supply hose 33. Then, the outlet pipe 312 is connected to the gas blasting head 2 by the blasting hose 34.

[0025] Then, several blasting holes are drilled at the location where blasting is required. The gas blasting head 2 is inserted into the blasting holes. Then, the gas storage mechanism 1 is opened, so that high-pressure gas is injected into the outlet branch pipe 312 along the main inlet pipe 311. Then, the operator uses the remote control 323 to operate the solenoid valve 313 in the valve box 31 to release the high-pressure gas instantly, achieving the effect of breaking the rock.

[0026] After the operation is completed, close the gas storage mechanism 1 and then open the pressure relief valve 315 to allow excess gas to be discharged along the pressure relief pipe 314, thereby achieving safe disassembly of the gas supply hose 33 and the burst hose 34 and meeting the safety requirements during disassembly.

[0027] Therefore, by using high-pressure air as the blasting gas source, which is non-toxic, harmless, safe and environmentally friendly, and does not require cumbersome approval procedures such as explosives, and the blasting process can be remotely controlled, this blasting method simultaneously meets the requirements of low price, low risk and adaptability to various operational needs.

[0028] like Figure 3 , Figure 4 , Figure 5 As shown, the gas storage mechanism 1 includes a support frame 11, a gas cylinder 12, a gas filling and discharging pipeline 13, and a control pipeline 14.

[0029] like Figure 3 , Figure 4 , Figure 5 As shown, the support frame 11 is vertically set on the ground, and the steel cylinders 12 are horizontally arranged on the support frame 11. Each steel cylinder 12 is equipped with a switch valve 15.

[0030] like Figure 3 , Figure 4 As shown, the air filling and emptying pipeline 13 includes a main compressed air pipe 131 and multiple compressed air branch pipes 132, with each compressed air branch pipe 132 respectively disposed between the main compressed air pipe 131 and the switch valve 15.

[0031] like Figure 3 , Figure 4 As shown, the middle part of the control pipeline 14 is connected to the compressed air main pipe 131, one end of which is connected to the air supply hose 33, and the other end is connected to the burst hose 34.

[0032] like Figure 3 , Figure 4 As shown, the control pipeline 14 includes an inflation pipeline 141 and an deflation pipeline 142. A three-way valve 143 is installed between the inflation pipeline 141 and the deflation pipeline 142, and the compressed air main pipeline 131 is connected to the three-way valve 143. An inflation valve 144 is installed on the inflation pipeline 141, and a deflation valve 145 is installed on the deflation pipeline 142.

[0033] like Figure 3 , Figure 4 As shown, a discharge pipe 146 is provided between the inflation valve 144 and the three-way valve 143. A discharge valve 147 is provided on the discharge pipe 146. A safety valve 148 is provided between the inflation pipe 141 and the discharge pipe 146. One end of the safety valve 148 is located between the inflation valve 144 and the discharge pipe 146, and the other end is located behind the discharge valve 147.

[0034] When the gas storage mechanism 1 is being filled, the air compressor is connected to the filling pipe 141, and then the filling valve 144 is opened, and the vent valve 145 and the discharge valve 147 are closed, so that the compressed air enters the three-way valve 143 along the filling pipe 141 and is injected into the compressed air main pipe 131. Finally, it is injected into the gas cylinder 12 along each compressed air branch pipe 132, thereby filling the gas cylinder 12 and completing the filling of the gas storage mechanism 1.

[0035] When the inflation pressure is too high, the safety valve 148 will automatically open, allowing the gas to bypass the discharge valve 147 and be discharged along the discharge pipe 146, ensuring safety during inflation. After inflation is complete, close the switch valve 15 on each cylinder 12, then open the discharge valve 147 to allow all gas in the pipelines to be discharged along the discharge pipe 146. Then, remove the air compressor, ensuring safety during disassembly.

[0036] When the gas storage mechanism 1 releases gas, the vent valve 145 is opened, the charging valve 144 and the discharge valve 147 are closed, so that the compressed air enters the three-way valve 143 along the charging pipe 141 and is injected into the vent pipe 142, thus completing the venting of the gas storage mechanism 1.

[0037] Furthermore, during the venting process of the gas storage mechanism 1, the gas pressure will not exceed the threshold set by the safety valve 148, so the safety valve 148 will not open, ensuring that the compressed air is discharged in one direction. After the venting is complete, the switch valve 15 on the cylinder 12 is closed, and then the discharge valve 147 is opened to allow the gas in all pipelines to be discharged along the discharge pipe 146, ensuring the safety of disassembling each component.

[0038] like Figure 3 , Figure 5 As shown, the support frame 11 includes a steel frame 111, a crossbeam 112, and a clamp 113.

[0039] like Figure 3 , Figure 5 As shown, the steel frame 111 is arranged in a frame shape. The upper end of the steel frame 111 is inclined with a canopy 114 to provide shade and rain protection for the entire gas storage mechanism 1. The lower end of the steel frame 111 is equipped with casters 115 to facilitate ground-based transportation of the gas storage mechanism 1. Lifting rings 116 are provided on both sides of the steel frame 111 to facilitate hoisting and transportation of the gas storage mechanism 1.

[0040] like Figure 3 , Figure 5 As shown, the crossbeam 112 is horizontally set on the steel frame 111, the clamp 113 clamps the steel cylinder 12 and is located on the crossbeam 112, and a shock-absorbing seat 117 is set between the crossbeam 112 and the clamp 113.

[0041] like Figure 3 , Figure 5As shown, a slide block 118 is vertically slidably connected to the tail end of the steel frame 111, and a groove 119 is provided on the slide block 118 for the tail end of the steel cylinder 12 to be inserted.

[0042] When installing the gas cylinder 12, insert the gas cylinder 12 into the clamp 113, and then adjust the position of the slide 118 so that the tail of the gas cylinder 12 is embedded in the groove 119 on the slide 118, thereby limiting the position of the gas cylinder 12. Then tighten the clamp 113 to clamp and fix the gas cylinder 12, thus completing the installation of the gas cylinder 12.

[0043] During transportation, the support frame 11 and the cylinder 12 are equipped with shock-absorbing seats 117 between the clamp 113 and the crossbeam 112, and the seat plate at the rear is slidably connected to the steel frame 111. This allows the cylinder 12 to move freely vertically, achieving shock absorption and buffering, thereby ensuring the safety and stability of the cylinder 12 during transportation.

[0044] like Figure 3 , Figure 5 As shown, a pipe rack 4 is provided on the front side of the steel frame 111. The pipe rack 4 is used to install and fix the inflation / deflation pipe 13 and the control pipe 14. The lower end of the pipe rack 4 is rotatably connected to the steel frame 111, and the upper end is provided with a buckle 41 for hooking the steel frame 111.

[0045] When installing the gas cylinder 12, first release the latch 41, then control the pipe 14 frame to flip, opening one end of the steel frame 111 to facilitate inserting the gas cylinder 12 into the steel frame 111. Then control the pipe 14 frame to flip in the opposite direction and use the latch 41 to secure it, achieving quick alignment of all interface positions. Finally, tighten the threaded heads at the connection positions to achieve a quick connection between the filling / discharging pipe 13 and the gas cylinder 12, allowing for quick disassembly and maintenance of the gas cylinder 12.

[0046] Furthermore, during the transportation of the gas storage device 1, the filling and discharging pipeline 13 can be disconnected from the gas cylinder 12 to prevent the connection between the gas cylinder 12 and the filling and discharging pipeline 13 from breaking, thus ensuring the safety of the transportation process.

[0047] The specific embodiments are merely illustrative of the present invention and are not intended to limit the invention. After reading this specification, those skilled in the art can make modifications to these embodiments without contributing any inventive step, but such modifications are protected by patent law as long as they are within the scope of the claims of the present invention.
