TECHNICAL FIELD

[0001] The present application belongs to the field of engineering blasting, and particularly relates to a flexible energy storage pipe with a hole plug and a flexible energy storage pipe with the same. BACKGROUND

[0002] Liquid oxygen phase change fracturing technology is to use liquid oxygen to be heated and gasified to expand, and then release high-pressure gas quickly to break rocks or fall coal. Since the technology has controllable expansion capacity, great power, and no shock wave, etc., it is widely applied to city improvement, city construction, and mineral exploitation fields.

[0003] Among them, the most critical part of the technology is the flexible energy storage pipe, which needs to be assembled on site by the staff, and then the assembled flexible energy storage pipe is loaded into the blast hole and the blast hole is plugged, and the ignition operation can be started. Although the liquid oxygen phase change fracturing technology accelerates the blasting construction time to a certain extent, the flexible energy storage pipe needs to be assembled on site. The conventional method is to assemble the flexible energy storage pipe required for the operation on site, which greatly reduces the construction efficiency, and the assembled flexible energy storage pipe does not form a unified standard. In the detonation process, it is easy to form a "dumb bomb", which needs to be checked and excluded by the operator. The above situation reduces the efficiency of the blasting operation and also leaves serious safety hazards. SUMMARY

[0004] Therefore, the present application aims to provide a flexible energy storage pipe with a hole plug and a flexible energy storage pipe with the same to solve the problems of no unified standard of the conventional flexible energy storage pipe, easy to form a dumb bomb, and low efficiency of on-site assembly.

[0005] To achieve the above-mentioned purpose, the present application adopts the following technical solutions. According to one aspect of the present application, a flexible energy storage pipe with a hole plug is provided, comprising:

[0006] The plug body is provided with a plurality of openings along the axial direction, and any opening serves as a wire inlet hole;

[0007] The liquid filling pipe is inserted into one opening;

[0008] The exhaust pipe is inserted into one opening, and the liquid filling pipe and the exhaust pipe are sealed with the corresponding openings after being inserted into the openings.

[0009] Further, the openings are arranged at equal intervals.

[0010] Further, the distance between each adjacent two openings is 10 mm.

[0011] Further, the plug body is in the shape of a stepped circular truncated cone, including a coaxially arranged hole circular plane and a cylindrical side wall.

[0012] Further, the hole circular plane has a diameter greater than that of the cylindrical side wall.

[0013] Further, the cylindrical side wall is provided with anti-skid protrusions.

[0014] Further, the anti-skid protrusions are in the shape of a circular ring, and a plurality of the anti-skid protrusions are arranged axially and spaced apart along the cylindrical side wall.

[0015] Further, the hole circular plane is made of hard plastic.

[0016] Further, the sealing treatment is performed by using hot melt adhesive.

[0017] According to another aspect of the present application, there is provided a flexible energy storage tube, including the hole plug of the flexible energy storage tube.

[0018] Compared with the prior art, the present application has the following advantages:

[0019] 1. The plug can fix the positions of the liquid filling tube, the exhaust tube and the wire inlet hole in advance, so that the operation is standardized, and the liquid filling tube and the exhaust tube can be inserted into the positions, and the connection is completed by necessary sealing means, so that the operation is simple and standardized, the technical level of the operator is low, and the fault tolerance is high.

[0020] 2. The design of the plug can improve the problem of "dumb bomb" caused by non-standard assembly of workers, improve the operation efficiency of blasting, reduce the assembly time of the flexible energy storage tube by 30%, effectively alleviate the difficulty of the worker's operation, avoid the defects of increasing the operation time, reducing the operation quality, increasing the probability of "dumb bomb" and increasing the operation time of the worker due to the too high assembly difficulty; the overall structure of the plug is simple and practical, and has great popularization value.

[0021] 3. The hole spacing of the plug is 10 mm, which can effectively prevent the low-temperature liquid oxygen in the liquid inlet tube from causing low-temperature cracking of the pipelines and lines in the other two holes, reduce the probability of "dumb bomb", and improve the safety during operation.

[0022] 4. The upper hole circular plane in the plug has a larger radius than the cylindrical side wall, so that the flexible energy storage tube can be limited below the hole circular plane, and the low-temperature liquid oxygen in the lower flexible energy storage tube can be prevented from affecting the upper pipeline of the hole circular plane.

[0031] Referring to the accompanying drawings, this embodiment of the invention provides a perforated plug for a flexible energy storage tube, comprising:

[0032] The plug body is provided with a plurality of openings along the axial direction, and any opening serves as a wire inlet hole 1-3. The openings can provide a standard structure, and only the corresponding pipe needs to be inserted, which requires low technical level of the operator and can reduce the probability of occurrence of a dud.

[0033] The liquid filling pipe 1-1 is inserted into an opening. The liquid filling pipe 1-1 is provided to flush in low-temperature liquid oxygen.

[0034] The exhaust pipe 1-2 is inserted into an opening, and the liquid filling pipe 1-1 and the exhaust pipe 1-2 are inserted into corresponding openings and sealed between the openings. The connection by insertion can improve the installation efficiency, and the sealing treatment can avoid air leakage, thereby improving the safety and stability of use. The entire installation process is simple and efficient, which helps to improve the work efficiency.

[0035] In this embodiment, the openings are arranged at equal intervals, which can form a better operation mode. The equal interval arrangement can easily find the next insertion point during installation. The distance between each adjacent two openings is 10 mm. The opening spacing of the plug is 10 mm, which can effectively prevent the low-temperature liquid oxygen in the liquid inlet pipe from causing low-temperature cracking of the pipelines and lines in the other two holes, reduce the probability of "dud" occurrence, and improve the safety during operation.

[0036] In this embodiment, the plug body is a stepped circular table shape including a coaxially arranged hole circular plane 1 and a cylindrical side wall 2. The diameter of the hole circular plane 1 is greater than that of the cylindrical side wall 2. This arrangement can restrict the flexible energy storage pipe below the hole circular plane, preventing the low-temperature liquid oxygen in the flexible energy storage pipe below from affecting the pipeline above the hole circular plane. The hole circular plane 1 and the cylindrical side wall 2 can be integrally formed by die stamping during production.

[0037] In this embodiment, the cylindrical side wall 2 is provided with anti-skid protrusions 2-1. The anti-skid protrusions 2-1 can reduce the risk of sliding of the flexible energy storage pipe and improve the stability of use.

This arrangement can provide multiple layers of defense in the axial direction, further improving the stability of the connection between the plug and the flexible energy storage pipe.

[0039] In this embodiment, the hole circular plane 1 is made of hard plastic. The material is easy to obtain, and the use cost is reduced.

[0040] In the embodiment, the sealing treatment mode is hot melt adhesive bonding. The hot melt adhesive bonding mode can help to form reliable sealing connection between the pipe and the hole, ensure the structure to be firm and stable, not easy to be damaged, and meanwhile, the operation is simple and easy to implement, and the work efficiency is improved.
