Description

Technical Field

[0001] The present application relates to the technical field of electronic detonators, and more specifically, to a green, energy-saving, high-precision electronic detonator. Background Art

[0002] With the continuous development of mining, construction and other fields, the demand for blasting operations is also increasing. At the same time, these fields have higher and higher requirements for the accuracy, safety, environmental protection and other aspects of blasting operations. Therefore, the market demand for green, energy-saving and high-precision detonators is also increasing. This market demand has driven the need for detonators to continue to develop in these directions to meet market demand and give birth to electronic detonators that are green, energy-saving and high-precision.

[0003] In the prior art, the sealing of the assembled detonator is achieved by squeezing or bayoneting the tube shell and the tube plug of the detonator. However, during the assembly process of the detonator, when the tube plug is inserted into the tube shell by squeezing or bayoneting, it is easy to cause scratches or wear on the sealing ring between the tube shell and the tube plug. Such damage will directly lead to the failure of its sealing, and then cause the moisture in the environment to easily invade the interior of the electronic detonator when it is stored, causing the electronic detonator to be damp. The dampness inside the detonator will accelerate the aging process of its internal components, such as the electrodes and wires of the electric detonator may be corroded and broken due to moisture. This will cause the performance of the detonator to decline, or even completely fail, affecting the service life of the electronic detonator and reducing the reliability of the use of the electronic detonator.

[0004] In view of this, we propose a green, energy-saving and high-precision electronic detonator. Summary of the invention

[0012] As an optional solution of the technical solution of the present application document, an annular compensation cavity is provided in the opening at the end of the tube shell, which can respectively accommodate an annular elastic sac membrane and an annular baffle membrane.

[0013] As an optional solution of the technical solution of the present application document, the sealing structure includes a sealing end cap connected to the end opening of the tube shell, and the sealing end cap is connected to a tube plug that can be inserted into the end opening of the tube shell; A circle of V-shaped annular grooves is arranged on the side wall of the pipe plug, into which the spike part can be movably inserted, and when the sealing end cover is closed and connected to the opening of the end of the pipe shell, the spike part and the V-shaped annular groove are arranged opposite to each other.

[0014] As an optional solution of the technical solution of this application document, the pipeline unit includes a connecting channel, a pressure relief channel, a negative pressure connection channel and a discharge channel; A narrow section is provided on the pressure relief channel; One end of the accommodating groove away from the water-absorbing resin particle layer is connected to the annular compensation cavity through a connecting channel; A one-way air inlet valve connected to the side wall of the ear connector is provided on the connecting passage; The internal sealing sliding of the output end of the pressure relief channel is provided with a pressure relief air plug, the pressure relief air plug is connected with an elastic band, and the other end of the elastic band is connected with a support fixed inside the pressure relief channel.

[0015] As an optional solution of the technical solution of this application document, the input end of the pressure relief channel is connected to the end of the accommodating groove away from the water-absorbing resin particle layer, and the output end penetrates the side wall of the ear connector and is connected to the atmosphere; The inner cavity of the tube shell and the narrow section are connected through a negative pressure connection channel; One end of the containing groove close to the water-absorbing resin particle layer is communicated with the inner cavity of the tube shell through an exhaust channel.

[0016] Beneficial effect: One or more technical solutions provided in the technical solution of the present application have at least the following technical effects or advantages: 1. When assembling the detonator, when the pre-installed sealing ring that seals the annular gap between the tube shell and the tube plug is scratched or worn and then fails, resulting in moisture intrusion into the tube shell structure, the water-absorbing resin particle layer in the sealing compensation part actively absorbs moisture and thereby reduces the humidity inside the tube shell structure. During the process, the volume gradually expands and drives the gas-generating structure to retract into the hollow plug tube. Subsequently, when the water medium part contacts the water-contact block through the connecting hole, a large amount of gas is quickly generated and input into the interior of the capsule compensation unit through the pipeline unit, driving the spare capsule compensation unit in a closed environment to quickly pop out of the annular compensation cavity and seal the gap between the tube shell and the tube plug again, thereby restoring the sealing performance of the detonator, ensuring the sealing and moisture-proof performance of the electronic detonator, and improving the reliability of the electronic detonator. It is also beneficial to extend the service life of the detonator.

[0017] 2. The gas-generating structure retracts into the interior of the hollow plug tube, so that the water medium part contacts the water-contacting block and quickly generates a large amount of gas. The gas then quickly fills the connecting channel and the pressure relief channel in the pipeline unit. When the gas enters the annular compensation cavity through the connecting channel and drives the cartridge compensation unit to expand elastically, the gas pressure further increases and pushes the pressure relief plug in the pressure relief channel connected to the accommodating groove, so that the excess gas generated by the moisture sensing unit can be discharged in time through the pressure relief channel, thereby preventing the shell structure from rupturing due to excessive gas filling when the cartridge compensation unit is ejected and the gap between the shell and the tube plug is sealed again. This achieves pressure relief protection for the ejected cartridge compensation unit for secondary sealing, ensures the stability of the internal air pressure of the ejected cartridge compensation unit, and further ensures the sealing protection effect of the electronic detonator.

[0018] 3. When the pressure relief plug located inside the output end of the pressure relief channel is pushed, the excess gas generated by the moisture sensing unit is discharged from the pressure relief channel. When the airflow passes through the narrow section on the pressure relief channel and accelerates, negative pressure is formed inside the negative pressure connection channel connected to the narrow section, and the air with moisture inside the tube shell structure is continuously extracted from the inside, which is beneficial to further reduce the humidity inside the tube shell structure. In the process of the electronic detonator actively performing secondary sealing treatment on the failed part when the sealing failure occurs, the internal moisture can be further extracted, so that the inside of the detonator can quickly restore to a dry environment, which can further reduce the degree of damage to the electronic detonator caused by moisture intrusion caused by sealing failure, thereby ensuring the reliability of the use of the electronic detonator.

The detachable block 1005 is removed from the end opening of the receiving groove, thereby facilitating the operator to replace the humidity sensing unit in the receiving groove as a whole.

[0033] Reference Figures 2 to 4 , the embodiment of the present application provides a green energy-saving high-precision electronic detonator, the moisture sensing unit includes a hollow plug cylinder 1006 and a water-absorbing resin particle layer 1013 filled in the receiving groove; When the removable block 1005 is sealed and connected to the end opening of the receiving groove, the hollow plug cylinder 1006 is horizontally sealed and slid in the receiving groove; The hollow plug cylinder 1006 is filled with a water medium portion 1014, and a placement opening is opened on the side wall of the hollow plug cylinder 1006, and a waterproof breathable membrane 1017 is connected to the placement opening; The end opening of the hollow plug cylinder 1006 is provided with a gas-generating structure that can cooperate with the water medium part 1014.

[0034] Reference Figure 4 and Figure 5 , the embodiment of the present application provides a green energy-saving high-precision electronic detonator, the gas-generating structure includes a hollow cooperative rod 1015 sealed and slidably inserted at the end of the hollow plug cylinder 1006; One end of the hollow cooperative rod 1015 extends into the hollow plug tube 1006 and is sealed with a closed end seat, and the closed end seat is connected to a spring connected between the inner end of the hollow plug tube 1006 and the closed end seat; The hollow cooperative rod 1015 is provided with a water contact generating block 1016 cooperating with the water medium portion 1014, and the water contact generating block 1016 is formed by pressing an effervescent disintegrant; A plurality of connecting holes are provided on the side wall of the hollow cooperative rod 1015 extending from the end of the hollow plug cylinder 1006, and when the spring is in the initial relaxed state, the connecting holes are located outside the hollow plug cylinder 1006; The hollow plug tube 1006 is located between the gas generating structure and the water-absorbing resin particle layer 1013 , and the water-absorbing resin particle layer 1013 is located at one end of the accommodating cavity close to the tube shell 1001 .

[0035] Reference Figure 2 , Figure 3 and Figure 6, the embodiment of the present application provides a green energy-saving high-precision electronic detonator, the capsule compensation unit includes an annular baffle membrane 1019 and an annular elastic capsule membrane 1004 arranged in inner and outer layers; A plurality of spikes 1018 are evenly connected to the outer wall of the annular elastic capsule membrane 1004; An annular compensation cavity is provided in the opening at the end of the tube shell 1001, which can respectively accommodate the annular elastic capsule membrane 1004 and the annular baffle membrane 1019. The annular elastic capsule membrane 1004 and the annular baffle membrane 1019 are both connected to the annular compensation cavity, and the annular baffle membrane 1019 blocks the opening of the annular compensation cavity. The annular baffle membrane 1019 installed in the annular compensation cavity seals the annular elastic capsule membrane 1004 in the annular compensation cavity before the annular elastic capsule membrane 1004 pops out of the annular compensation cavity, thereby avoiding the contact of the annular elastic capsule membrane 1004 with oxygen, humid environment or corrosive substances, so its aging speed will be slower, which helps to extend the service life of the annular elastic capsule membrane 1004 in the capsule compensation unit.

[0036] When assembling the detonator, when the pre-installed sealing ring 1003 that seals the annular gap between the tube shell 1001 and the tube plug 202 is scratched or worn and then fails, causing moisture to invade the tube shell structure 10, the water-absorbing resin particle layer 1013 in the sealing compensation part actively absorbs moisture and thereby reduces the humidity inside the tube shell structure 10, and its volume gradually expands and drives the gas-generating structure to retract into the hollow plug tube 1006. Subsequently, when the water medium part 1014 contacts the water contact generating block 1016 through the connecting hole, a large amount of gas is quickly generated and input into the capsule compensation unit through the pipeline unit, driving the spare capsule compensation unit in a closed environment to quickly pop out of the annular compensation cavity and seal the gap between the tube shell 1001 and the tube plug 202 again, thereby restoring the sealing performance of the detonator.

[0037] Reference Figure 2 , Figure 3 and Figure 6 The embodiment of the present application provides a green energy-saving high-precision electronic detonator, wherein the capping structure 20 comprises a sealing end cap 201 which is connected to the end opening of the tube shell 1001, and a pipe plug 202 which can be inserted into the end opening of the tube shell 1001 is connected to the sealing end cap 201; A circle of V-shaped annular grooves 203 is arranged on the side wall of the tube plug 202 for the spike portion 1018 to be movably inserted therein, and when the sealing end cover 201 is closed and connected to the opening at the end of the tube shell 1001, the spike portion 1018 and the V-shaped annular groove 203 are arranged opposite to each other, and when the annular elastic capsule membrane 1004 is ejected from the annular compensation cavity under the action of air pressure, the elastically expanded annular elastic capsule membrane 1004 first drives the spike portion 1018 to pierce the annular baffle membrane 1019, and when the annular elastic capsule membrane 1004 is ejected from the annular compensation cavity, the spike portion 1018 is inserted into the V-shaped annular groove 203, and the ejected annular elastic capsule membrane 1004 is tightly attached to the side wall of the tube plug 202, thereby re-sealing the gap between the tube shell 1001 and the tube plug 202.

[0038] Reference Figures 2 to 4 , the embodiment of the present application provides a green and energy-saving high-precision electronic detonator, the pipeline unit includes a connecting channel, a pressure relief channel 1007, a negative pressure connection channel 1009 and a discharge channel; The input end of the pressure relief channel 1007 is connected to the end of the accommodating groove away from the water-absorbing resin particle layer 1013, and the output end passes through the side wall of the ear connector 1002 and is connected to the atmosphere; A narrow section 1008 is provided on the pressure relief channel 1007; The inner cavity of the tube shell 1001 and the narrow section 1008 are connected through a negative pressure connection channel 1009; One end of the accommodating groove away from the water-absorbing resin particle layer 1013 is connected to the annular compensation cavity through a connecting channel; One end of the accommodating groove close to the water-absorbing resin particle layer 1013 is connected to the inner cavity of the tube shell 1001 through an exhaust passage; A one-way air inlet valve 1012 connected to the side wall of the ear connector 1002 is provided on the connecting passage; The output end of the pressure relief channel 1007 is internally sealed and slidably provided with a pressure relief air plug 1010 , to which an elastic band 1011 is connected, and the other end of the elastic band 1011 is connected to a support fixed inside the pressure relief channel 1007 .

[0039] The gas-generating structure retracts into the hollow plug tube 1006, so that the water medium part 1014 contacts the water-contact generating block 1016 and quickly generates a large amount of gas, and the gas quickly fills the connecting channel and the pressure relief channel 1007 in the pipeline unit. When the gas enters the annular compensation cavity through the connecting channel and drives the capsule compensation unit to elastically expand, the gas pressure further increases and pushes the pressure relief gas plug 1010 in the pressure relief channel 1007 connected to the accommodating groove, so that the excess gas generated by the moisture sensing unit can be discharged in time through the pressure relief channel 1007, avoiding the shell and tube structure 10 from rupturing due to excessive gas filling when the capsule compensation unit is ejected and the gap between the shell and tube 1001 and the tube plug 202 is re-sealed, thereby realizing pressure relief protection for the ejected capsule compensation unit for secondary sealing, and ensuring the stability of the internal air pressure of the ejected capsule compensation unit.

[0040] When the pressure relief plug 1010 located inside the output end of the pressure relief channel 1007 is pushed, the excess gas generated by the moisture sensing unit is discharged from the pressure relief channel 1007. When the airflow passes through the narrow section 1008 on the pressure relief channel 1007 and accelerates, a negative pressure is formed inside the negative pressure connection channel 1009 connected to the narrow section 1008, and the air with moisture inside the tube shell structure 10 is continuously extracted from the inside, which is beneficial to further reduce the humidity inside the tube shell structure 10, so that the electronic detonator can actively perform secondary sealing treatment on the failed part in the event of sealing failure, and can further extract the internal moisture, so that the inside of the detonator can quickly restore to a dry environment, which can further reduce the degree of damage to the electronic detonator caused by moisture intrusion caused by sealing failure, thereby ensuring the reliability of the use of the electronic detonator.

[0041] The detonator in the present application is an electronic detonator. Since the manufacturing materials of electronic detonators tend to be environmentally friendly and do not contain or reduce the use of harmful substances, they embody their green characteristics. Since electronic detonators can accurately control explosion parameters, such as the intensity, time, and location of the explosion, they avoid energy waste caused by insufficient or excessive explosion intensity, thereby achieving energy-saving effects. Electronic detonators use digital circuits and microprocessor control to achieve precise time control and multiple modes of blasting. This digital control method makes the explosion process more controllable and accurate.

[0042] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit it. Although the present application has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present application.
