Description

Technical Field

[0001] This utility model relates to the field of mountain blasting technology, and in particular to a controlled mass fracture release device for high-pressure gas in mountain blasting. Background Technology

[0002] Mountain blasting is a crucial step in mining, tunnel construction, and infrastructure development. Traditional blasting relies heavily on explosives, but this method suffers from low safety, significant environmental pollution, and complex approval processes. In recent years, high-pressure gas blasting technology (such as carbon dioxide fracturing devices) has become a research hotspot due to its advantages in safety, environmental friendliness, and controllability. This technology uses the energy released instantaneously by high-pressure gas to fracture rock masses, avoiding the vibrations, flyrock, and harmful gases caused by explosives. It is also adaptable to complex working conditions and does not require strict pyrotechnics management procedures. With advancements in intelligent control and materials science, the precision and efficiency of high-pressure gas blasting continue to improve, and its future applications in green mining and urban demolition are promising, driving the development of engineering blasting towards low-carbon and refined methods.

[0003] Traditional high-pressure gas blasting equipment is typically designed for intact, homogeneous rock masses, with pressure relief holes machined directly inside the pressure relief head, forming a fixed, integrated structure. However, in practical engineering applications, especially in complex rock formations or under high-frequency operating conditions, the pressure relief holes are prone to failure due to high-pressure impact, debris blockage, or fatigue wear. When the pressure relief hole structure fails, it is necessary to replace the pressure relief head or even the entire device, which is inconvenient for maintenance, increases maintenance costs, and affects the progress of mountain blasting work. Utility Model Content

[0004] In order to overcome the shortcomings of the existing technology, the purpose of this utility model is to provide a controlled mass fracture release device for high-pressure gas in mountain blasting, which is easy to maintain and thus reduces maintenance costs.

[0005] The objective of this utility model is achieved through the following technical solution:

[0006] A controlled mass fission release device for high-pressure gas during mountain blasting includes:

[0007] A cylindrical body having a cavity, the cylindrical body being provided with a pressure relief mechanism located within the cavity to divide the cavity into a liquid storage cavity and a gas flow injection cavity; the liquid storage cavity is used to contain liquid gas; the gas flow injection cavity has a nozzle for supplying gas flow from the gas flow injection cavity to the external environment;

[0008] An excitation device is disposed within the liquid storage chamber and is used to heat the liquid gas;

[0009] The cylinder is connected to a mounting ring, which is located at the nozzle. The mounting ring has an axial insertion through hole and an annular limiting groove. The annular limiting groove extends axially around the axial insertion through hole and is recessed from the inside to the outside of the mounting ring from the hole wall. The mounting ring also has a disassembly guide groove, which extends axially along the mounting ring until it connects with the annular limiting groove. The disassembly guide groove is recessed from the inside to the outside of the mounting ring from the hole wall.

[0010] The nozzle is inserted into the axial insertion through hole, the inlet of the nozzle is connected to the nozzle outlet, the nozzle is provided with an axial limiting block, the axial limiting block slides into the annular limiting groove along the installation and removal guide groove, and is spaced apart from the installation and removal guide groove along the circumference of the axial insertion through hole; the axial limiting block is connected to the mounting ring by a locking member.

[0011] Furthermore, the pressure relief mechanism comprises a rupture disc and a limiting collar, wherein the limiting collar is provided with an annular groove, and the limiting collar is axially sleeved within the liquid storage cavity, thereby engaging the rupture disc with the annular groove.

[0012] Furthermore, the cylinder also includes a filling head, which is connected to the excitation device to support it. The filling head is threadedly connected to the cylinder so that the excitation device is located inside the liquid storage chamber.

[0013] Furthermore, the activation device has a heating tube and a detonation wire, the heating tube being electrically connected to the detonation wire, and the detonation wire being electrically connected to the detonation button of the activation device.

[0014] Furthermore, the locking element is a screw, the mounting ring is provided with the axial threaded hole, the screw is threaded to the axial threaded hole and inserted into the axial insertion hole of the axial limiting block.

[0015] Furthermore, the mounting ring is threadedly connected to the cylinder.

[0016] Furthermore, the outer wall of the filling head is provided with a scale, which is used to identify the orientation of the nozzle.

[0017] Furthermore, an auxiliary pointer is detachably inserted at one end of the nozzle located at the nozzle opening. The auxiliary pointer extends radially from the inside to the outside of the cylinder so that the outer end of the auxiliary pointer protrudes outside the cylinder. The auxiliary pointer is used to cooperate with the dial.

[0018] Furthermore, the outer wall of the end of the cylinder used for insertion into the rock stratum is provided with a guide plate, and multiple guide plates are provided, which are distributed circumferentially around the cylinder at intervals.

[0019] Furthermore, the nozzle outlet is set at a non-zero angle with the axis of the axial insertion through hole.

[0020] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0021] 1. Based on the cylinder body connected to the nozzle at the gas injection chamber, the mounting ring has an axial insertion through hole, an annular limiting groove, and an installation guide groove. The nozzle is equipped with an axial limiting block. The locking device can lock the nozzle to the mounting ring. When the nozzle is damaged beyond repair due to the blasting intensity, the locking device can be released from the nozzle and the mounting ring. The nozzle can be replaced or repaired simply by removing the nozzle and the axial limiting block from the annular limiting groove and the installation guide groove of the mounting ring. It is not necessary to replace the entire high-pressure gas controlled mass fracturing device for mountain blasting. While enabling convenient maintenance of the nozzle, the locking device can also enhance the stability of the nozzle in the mounting ring, which helps to reduce the maintenance cost of the entire high-pressure gas controlled mass fracturing device for mountain blasting, improve the efficiency of mountain blasting, and speed up the work progress.

[0022] 2. Since the nozzle is indirectly installed in the airflow injection chamber of the cylinder through the mounting ring, when the nozzle needs to be disassembled and the axial insertion hole of the mounting ring needs to be adapted to different sizes of nozzles, only the mounting ring needs to be replaced to disassemble and install nozzles of different sizes. It is not necessary to replace the entire high-pressure gas controlled mass fracturing device for mountain blasting, which saves disassembly and assembly time and reduces maintenance costs. During blasting, the nozzle is subjected to high-pressure jet and applies radial pressure to the mounting ring. This pressure is successively weakened as it is transmitted to the mounting ring and the cylinder. Since the pressure applied to the cylinder also generates a reverse reaction force, the degree of damage to the nozzle by the reaction force is reduced, the replacement frequency of the nozzle is reduced, and thus the maintenance cost is reduced.

[0032] See Figures 1-5 A preferred embodiment of this utility model is described below:

[0033] See Figure 1 , Figure 2 A controlled mass fission release device for high-pressure gas in mountain blasting includes a cylinder 1, an excitation device 4, and a nozzle 9.

[0034] The cylinder 1 has a cavity 2, and the cylinder 1 is equipped with a pressure release mechanism 3 located in the cavity 2. The pressure release mechanism 3 can be a rupture disc 301 (also known as a bursting disc), a pressure relief valve, or a shear pin, etc., which can control the release of high-pressure gas. It can be appropriately selected according to the assembly cost and the use environment. The pressure release mechanism 3 divides the cavity 2 into a liquid storage cavity 201 and a gas jet cavity 202, making both closed environments. The liquid storage cavity 201 is used to contain liquid gas. The gas used for detonation can be carbon dioxide, nitrogen (compressed state), air (compressed state), or a mixture of gases. It can be appropriately selected based on the balance between cost, blasting effect, and environmental protection effect. The gas jet cavity 202 has a nozzle 212. The nozzle 212 is used to allow gas to be ejected from the gas jet cavity 202 to the external environment. The outlet direction of the nozzle 212, i.e. the release direction of the high-pressure gas, can be different and can be freely set according to the preset orientation of the rock layer to be blasted.

[0035] The activating device 4 is located inside the liquid storage chamber 201 and is used to heat the liquid gas. Taking liquid gas as an example, before the explosion, the gas is filled in a high-pressure liquid state, occupying part of the volume of the liquid storage chamber 201. After the activating device 4 is activated, the liquid gas absorbs heat and vaporizes, and its volume expands rapidly (liquid state → gas state → supercritical state). The pressure inside the liquid storage chamber 201 rises sharply (generally reaching 200-300 MPa) until it reaches the threshold of the pressure release mechanism 3. The pressure release mechanism 3 begins to release high-pressure gas. The high-pressure gas is ejected from the airflow jet chamber 202 to the external environment. The ejected high-pressure gas forms a high-speed jet that extends along the preset rock mass fissures or weak surfaces, achieving mass fracturing.

[0036] See Figure 5 The cylinder body 1 is connected to an installation ring 5, which is located at the nozzle 212. The installation ring 5 has an axial insertion through hole 6 and an annular limiting groove 7. The annular limiting groove 7 extends axially around the axial insertion through hole 6 and is recessed from the inside to the outside of the installation ring 5 from the hole wall of the axial insertion through hole 6. The installation ring 5 also has a disassembly guide groove 8, which extends axially along the installation ring 5 until it connects with the annular limiting groove 7. The disassembly guide groove 8 is recessed from the inside to the outside of the installation ring 5 from the hole wall of the axial insertion through hole 6. The installation ring 5 can be detachably connected to the cylinder body 1, such as by threaded connection or clamp connection, for easy disassembly and maintenance.

[0037] The nozzle 9 is inserted into the axial insertion through hole 6. The inlet of the nozzle 9 is connected to the nozzle 212. The nozzle 9 is provided with an axial limiting block 10. The axial limiting block 10 slides into the annular limiting groove 7 along the installation and removal guide groove 8 and is spaced apart from the installation and removal guide groove 8 along the circumference of the axial insertion through hole 6. The axial limiting block 10 is connected to the mounting ring 5 through a locking member 11, which can be a screw or a pin, etc. When installing the nozzle 9 to the mounting ring 5, first align the axial limiting block 10 with the installation and removal guide groove 8. After the axial limiting block 10 slides into the installation and removal guide groove 8 and reaches the bottom of the annular limiting groove 7, rotate the nozzle 9 relative to the annular limiting groove 7 until the axial limiting block 10 can no longer be dislodged from the installation and removal guide groove 8. Then, the nozzle 9 is fixed to the mounting ring 5. Finally, the locking member 11 is used to further secure it to prevent the nozzle 9 from falling off the mounting ring 5 due to vibration during explosion. This is both convenient and practical. The axial insertion through hole 6 of the mounting ring 5 can be adapted to nozzles 9 of different sizes, so as to facilitate the disassembly, assembly and maintenance of nozzles 9. Maintenance does not require replacing the entire device, thus reducing maintenance costs.

[0038] The working principle of this utility model of a high-pressure gas controlled mass fracturing device for mountain blasting is as follows: The pressure release mechanism 3 is pre-set with a threshold value, and the pressure release mechanism 3 and the excitation device 4 are installed in the liquid storage chamber 201 of the cylinder 1. When installing the nozzle 9 and the mounting ring 5, the mounting ring 5 is first installed at the nozzle 212 of the gas injection chamber of the cylinder 1. The nozzle 9 is aligned and slid into the axial insertion through hole 6 of the mounting ring 5. Simultaneously, the axial limiting block 10 of the nozzle 9 is aligned and slid into the installation and removal guide groove 8 extending axially along the mounting ring 5 until it connects to the annular limiting groove 7 of the mounting ring 5. Then, by circumferentially moving the nozzle 9, the axial limiting block 10 moves circumferentially within the annular limiting groove 7 until the axial limiting block 10 cannot detach from the annular limiting groove 7 and the installation and removal guide groove 8. Finally, the axial limiting block 10 is secured in the mounting ring 5 using the locking element 11; then, liquid gas is filled into the storage chamber 201 and sealed, and then the entire device is placed at the pre-cracked surface of the rock mass, so that the nozzle 9 is aligned with the pre-cracked surface of the rock mass to be blasted through the nozzle 212 of the gas injection chamber; then, the workers move away from the blasting site and power on the ignition device 4 and detonate it. When detonated, the liquid gas in the storage chamber 201 absorbs heat and vaporizes, its volume expands rapidly, and the pressure inside the pipe rises sharply until it reaches the threshold of the pressure release mechanism 3. After the gas breaks through the pressure release mechanism 3, it forms a high-speed jet and is ejected from the inlet of the nozzle 9 through the nozzle 212 of the gas injection chamber. The high-pressure jet extends along the cracks or weak surfaces of the rock mass to achieve structural cracking, thus completing the blasting of the entire mountain.

[0039] The cylinder 1 is connected to an installation ring 5 located at the nozzle 212 of the gas injection chamber. The installation ring 5 has an axial insertion through hole 6, an annular limiting groove 7, and an installation guide groove. The nozzle 9 is provided with an axial limiting block 10. The locking member 11 can lock the nozzle 9 to the installation ring 5. When the nozzle 9 is damaged to the point of being unusable due to the blasting intensity, the locking member 11 can be used to release the nozzle 9 from the installation ring 5. The nozzle 9 can be replaced or repaired simply by removing the nozzle 9 along with the axial limiting block 10 from the annular limiting groove 7 and the installation guide groove of the installation ring 5. It is not necessary to replace the entire high-pressure gas controlled mass fracturing device for mountain blasting. While enabling convenient maintenance of the nozzle 9, the locking member 11 can strengthen the stability of the nozzle 9 in the installation ring 5, which helps to reduce the maintenance cost of the entire high-pressure gas controlled mass fracturing device for mountain blasting, improve the working efficiency of mountain blasting, and speed up the work progress.

[0040] Since the nozzle 9 is indirectly installed in the airflow injection chamber 202 of the cylinder 1 through the mounting ring 5, when the nozzle 9 needs to be disassembled and installed and the axial insertion hole of the mounting ring 5 needs to be adapted to different sizes of nozzle 9, only the mounting ring 5 needs to be replaced to disassemble and install nozzles 9 of different sizes. It is not necessary to replace the entire high-pressure gas controlled mass fracturing device for mountain blasting, which saves disassembly and assembly time and reduces maintenance costs. During blasting, the nozzle 9 is subjected to high-pressure jet and applies radial pressure to the mounting ring 5. This pressure is successively weakened as it is transmitted to the mounting ring 5 and the cylinder 1. Since the pressure applied to the cylinder 1 also generates a reverse reaction force, the degree of damage to the nozzle 9 by the reaction force is reduced, the replacement frequency of the nozzle 9 is reduced, and thus the maintenance cost is reduced.

[0041] Preferably, see Figure 4 The pressure relief mechanism 3 consists of a rupture disc 301 and a limiting collar 302. The limiting collar 302 has an annular groove. The limiting collar 302 is axially sleeved in the liquid storage chamber 201 and the rupture disc 301 is engaged in the annular groove, so that the rupture disc 301 is fixed in the liquid storage chamber 201. The rupture disc 301 can be further tightened by bolts or threaded caps. The limiting collar 302 can also be equipped with a sealing ring such as a copper gasket or a PTFE gasket to enhance the sealing of the entire liquid storage chamber 201 and prevent liquid gas from entering the gas jet chamber 202 from the liquid storage chamber 201 before the explosion.

[0042] Preferably, see Figure 2 The cylinder 1 also includes a filling head 12, which is connected to the excitation device 4 to support the excitation device 4. The filling head 12 is threadedly connected to the cylinder 1 so that the excitation device 4 is located in the liquid storage chamber 201, so as to facilitate the maintenance of the excitation device 4.

[0043] Preferably, the activating device 4 has a heating tube 401 and a detonating wire 402. The heating tube 401 is electrically connected to the detonating wire 402, and the detonating wire 402 is electrically connected to the detonation button of the activating device 4. The heating tube 401 can be a resistance wire heating tube 401, a chemical exothermic heating tube 401, or a semiconductor heating element (PTC). If only cost is considered, a resistance wire heating tube 401 is generally used. With the help of an external power supply, the detonating wire 402, and the detonation button, the activating device 4 can be remotely controlled to achieve remote detonation.

[0044] Preferably, see Figure 2 , Figure 5 The locking element 11 is a screw, and the mounting ring 5 is provided with an axial threaded hole. The screw is threaded into the axial threaded hole and inserted into the axial insertion hole of the axial limiting block 10. The screw in the threaded hole enables the nozzle 9 to be detachably connected to the mounting ring 5, which is very suitable for high-load environments such as high-pressure gas explosion.

[0045] The mounting ring 5 is threadedly connected to the cylinder 1. The threaded connection enables the mounting ring 5 and the cylinder 1 to be detachably connected, reducing relative slippage and indirectly stabilizing the connection between the nozzle 9 and the cylinder 1.

[0046] Preferably, see Figure 3 The outer wall of the filling head 12 is provided with a scale 13, which is used to identify the orientation of the nozzle 212. The direction of high-pressure gas release is accurately identified by the scale 13, which avoids the high-pressure jet from blindly spraying onto the rock layer and improves the accuracy of controllable rock mass fracture.

[0047] Preferably, see Figure 1 , Figure 2 An auxiliary pointer 14 is detachably inserted at one end of the nozzle 9 located at the nozzle 212. The auxiliary pointer 14 extends radially from the inside to the outside of the cylinder 1 so that the outer end of the auxiliary pointer 14 is exposed outside the cylinder 1. The auxiliary pointer 14 is used to cooperate with the dial 13. By installing the auxiliary pointer 14 and making the direction of the tip of the auxiliary pointer 14 consistent with the outlet direction of the nozzle 9, when cooperating with the dial 13, the auxiliary pointer 14 can be aligned with the scale of the dial 13 to accurately identify the outlet direction of the nozzle 9 (i.e., the direction of high-pressure gas release). When the high-pressure gas controlled mass fracturing device for mountain blasting is placed into the rock mass, the outlet direction of the nozzle 9 is adjusted by the dial 13 according to the pre-fracturing direction of the rock layer to be blasted. At the same time, the auxiliary pointer 14 is removed from the nozzle 9. The entire device can be placed in the rock mass while the high-pressure gas release direction is aligned with the pre-fracturing direction of the rock layer to be blasted, which is beneficial to improving the working efficiency of mountain blasting.

[0048] Preferably, the outer wall of the upper end of the cylinder 1 used for insertion into the rock layer is provided with a guide plate 15. Multiple guide plates 15 are provided and are distributed around the circumference of the cylinder 1 at intervals. When the high-pressure gas controlled fracturing device for mountain blasting enters the rock layer, the guide plate 15 can play a guiding role to prevent the entire device from deviating from the preset trajectory of entering the rock mass, and at the same time protect the nozzle 9 from damage by rocks.

[0049] Preferably, see Figure 5 The outlet of nozzle 9 is set at a non-zero angle with the axis of the axial insertion through hole 6. Based on this standard, nozzles 9 with different angles can be designed. Furthermore, by replacing nozzles 9 with different angles, the release direction of high-pressure gas in the rock mass can be further changed, thereby improving the controllability of high-pressure gas on rock mass fractures.
