Description

Technical Field

[0001] This utility model belongs to the field of gas blasting technology, and in particular relates to a segmented blasting device for carbon dioxide gas. Background Technology

[0002] In mining, tunnel excavation, and various engineering construction fields, blasting operations are an important means of achieving rock breaking and earthwork excavation. With the continuous improvement of requirements for safe production and environmental protection, carbon dioxide gas blasting technology has emerged. Carbon dioxide gas blasting is a relatively safe and environmentally friendly blasting method. It uses the pressure generated by the rapid vaporization and expansion of liquid carbon dioxide when heated to carry out blasting, avoiding many safety and environmental problems caused by explosive blasting.

[0003] Currently available carbon dioxide gas segmented detonators suffer from uneven energy release during detonation, resulting in unsatisfactory detonation effects. They also lack effective buffering devices, and the impact force generated at the moment of detonation can easily damage the detonator's structure, affecting its service life. Furthermore, the unreasonable design of the energy dissipation structure reduces the applicability and practicality of the detonator.

[0004] To address these issues, we provide a segmented carbon dioxide gas detonator. Utility Model Content

[0005] The purpose of this invention is to provide a segmented carbon dioxide gas blasting device. By using a venting head and a buffer mechanism in combination, it solves the problems of uneven energy release during the blasting process in existing blasting devices, which leads to unsatisfactory blasting effects, lack of effective buffering devices, and easy damage to the blasting device's own structure caused by the impact force generated at the moment of blasting.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution.

[0007] This utility model relates to a segmented carbon dioxide gas detonator, comprising a main body, an energy release head on one side of the main body, a buffer mechanism on the other side of the main body, a connecting seat fixedly connected to one side of the top of the main body, an inflation head connected to one side of the top of the connecting seat, and a detonating head connected to the other side of the top of the connecting seat. One side of the detonating head penetrates the top of the connecting seat and extends into the inner cavity of the main body. A heating element is fixedly connected to the bottom of the detonating head. The buffer mechanism includes a hydraulic cylinder, a cylinder cover fixedly connected to one side of the hydraulic cylinder, and one side of the cylinder cover communicating with the main body. The cylinder has a piston inside, and a rod is fixedly connected to one side of the piston. One side of the rod passes through the cylinder's inner cavity and extends to the cylinder head's inner cavity. A buffer plate is fixedly connected to one side of the rod. The main body is made of alloy steel, which has good pressure resistance and wear resistance. Its internal cavity wall is polished to reduce gas flow resistance. The piston uses a sealing structure to ensure that hydraulic oil will not leak under high pressure. The sealing material is a high-pressure resistant and wear-resistant rubber material. The surface of the buffer plate slides against the inner wall of the cylinder head, allowing it to directly contact the high-pressure gas and simultaneously seal the cylinder head.

[0008] The present invention is further configured such that an arc-shaped groove is formed on the surface of the piston, and a sealing gasket is provided in the inner cavity of the arc-shaped groove. The sealing gasket is installed inside the arc-shaped groove and located on the surface of the piston. During the movement of the piston, it rubs against the oil cylinder. The sealing gasket can improve the sealing effect while reducing friction and improving the service life of the piston.

[0009] The present invention is further configured such that a sealing cover is fixedly connected to one side of the oil cylinder, and a fixing nut is threadedly connected to the surface of the sealing cover. The sealing cover and the fixing nut are used to seal the oil cylinder and prevent leakage of hydraulic oil inside the oil cylinder.

[0010] The present invention is further configured such that the surface of the energy release head is provided with four vent holes, which are distributed circumferentially. The vent holes are distributed circumferentially on the surface of the energy release head, which can uniformly and quickly eject high-pressure gas and improve the stability of the main body during the blasting process.

[0011] The present invention is further configured such that a screw is fixedly connected to one side of the energy release head, and one side of the screw is threadedly connected to the main body. A first sealing ring, an energy release plate, and a second sealing ring are respectively provided at the connection between the screw and the energy release head. The screw connects the energy release head and the main body, and the connection is sealed by the first sealing ring, the energy release plate, and the second sealing ring to prevent gas leakage before explosion.

[0012] The present invention is further configured such that the other side of the energy venting head is a conical structure, the energy venting head is a hollow structure, and the conical structure at one end of the energy venting head can better connect with the predetermined position, ensuring the stability of the main body installation.

[0013] The present invention is further configured such that a guide vane is provided on one side of the inner cavity of the main tube, the guide vane being composed of spiral guide blades, one side of the guide vane extending to the opening of the main tube, the guide vane being composed of spiral guide blades, when the high-pressure gas expands in the tube, the guide vane guides the gas to flow in a specific direction, so that the energy of the gas is converted more into the impact force on the blasting target, rather than the recoil force.

[0014] The present invention has the following beneficial effects.

[0015] 1. During the gas blasting process of this utility model, when high-pressure gas is generated in the main pipe and surges towards the blasting outlet, some of the gas enters the buffer mechanism, which pushes the buffer plate to move. The buffer plate drives the rod to move, and the rod drives the piston to move. The piston causes hydraulic oil to flow between the chambers. The energy of the high-pressure gas is consumed by the viscosity resistance and flow resistance of the hydraulic oil, thereby reducing the magnitude of the recoil force.

[0016] 2. This utility model involves placing the main tube in a predetermined position, connecting the inflation head of the main tube to a high-pressure gas source, and injecting high-pressure gas into the tube according to a predetermined gas injection plan. Once the rated pressure is reached, an external detonation device is used to release the high-pressure gas in the tube instantly through the detonation head connected to the heating tube. The high-pressure gas is discharged through the vent hole, achieving the purpose of efficient blasting. Attached Figure Description

A heating tube 6 is fixedly connected to the bottom of the detonating head 5. The buffer mechanism includes a hydraulic cylinder 7, a cylinder cover 8 fixedly connected to one side of the hydraulic cylinder 7, and one side of the cylinder cover 8 communicating with the main body 1. A piston 9 is provided in the inner cavity of the hydraulic cylinder 7, a rod 10 fixedly connected to one side of the piston 9, and one side of the rod 10 penetrates the inner cavity of the hydraulic cylinder 7 and extends into the inner cavity of the cylinder cover 8. A buffer plate 11 is fixedly connected to one side of the rod 10.

[0027] Specifically: the main body 1 is made of alloy steel, which has good pressure resistance and wear resistance. Its internal cavity wall is polished to reduce gas flow resistance. The piston 9 adopts a sealing structure to ensure that hydraulic oil will not leak under high pressure. The sealing material is selected from high pressure resistant and wear resistant rubber material. The surface of the buffer plate 11 slides with the inner wall of the cylinder head 8, which can directly contact the high pressure gas and at the same time can seal the cylinder head 8.

[0028] Example 2

[0029] Please see Figure 1-5Based on Embodiment 1, the piston 9 has an arc-shaped groove on its surface, and a sealing gasket 12 is provided in the inner cavity of the arc-shaped groove. A sealing cover 13 is fixedly connected to one side of the oil cylinder 7, and a fixing nut is threadedly connected to the surface of the sealing cover 13. The surface of the energy release head 2 has four vent holes 14, which are circumferentially distributed. A screw 15 is fixedly connected to one side of the energy release head 2, and one side of the screw 15 is threadedly connected to the main body 1. A first sealing ring 16, an energy release plate 17, and a second sealing ring 18 are respectively provided at the connection between the screw 15 and the energy release head 2. The other side of the energy release head 2 is a conical structure. The energy release head 2 is a hollow structure. A guide plate 19 is provided on one side of the inner cavity of the main body 1. The guide plate 19 is composed of spiral guide vanes, and one side of the guide plate 19 extends to the opening of the main body 1.

[0030] Specifically: the sealing gasket 12 is installed inside the arc-shaped groove and located on the surface of the piston 9. During the movement of the piston 9, it rubs against the cylinder 7. The sealing gasket 12 can improve the sealing effect while reducing friction and improving the service life of the piston 9. The sealing cover 13 and the fixing nut are used to seal the cylinder 7 to prevent leakage of hydraulic oil inside the cylinder 7. The vent hole 14 is circumferentially distributed on the surface of the energy release head 2, which can uniformly and quickly spray out high-pressure gas, improving the stability of the main body 1 during the explosion process. The screw 15 connects the energy release head 2 to the main body 1.

One end of the energy release head 2 is a conical structure, which can better insert into the predetermined position to ensure the stability of the main body 1 installation. The guide plate 19 is composed of spiral guide vanes. When the high-pressure gas expands in the pipe, the guide vanes guide the gas to flow in a specific direction, so that the energy of the gas is converted into more impact force on the explosion target, rather than recoil force.

[0031] The working principle of this utility model is as follows: After placing the main body 1 in a predetermined position, the inflation head 4 of the main body 1 is connected to the gas source, and carbon dioxide gas is injected into the pipe. After the rated pressure is reached, the high-pressure gas in the pipe is released instantaneously through the external detonation device, which connects the detonation head 5 to the heating tube 6. The high-pressure gas is discharged through the vent hole 14, achieving the purpose of efficient blasting. During the gas blasting process of this blaster, when high-pressure gas is generated in the main body 1 and surges towards the blast outlet, some gas enters the buffer mechanism, pushing the buffer plate 11 to move. The buffer plate 11 drives the rod 10 to move, and the rod 10 drives the piston 9 to move. The piston 9 causes hydraulic oil to flow between the chambers. The energy of the high-pressure gas is consumed by the viscosity resistance and flow resistance of the hydraulic oil, thereby reducing the magnitude of the recoil force.
