Description

blasting wire connection structure

[0001] The present invention relates to a wire connection structure for blasting, and more specifically, to a wire connection structure for blasting in which a light-emitting function is provided in each wire connecting a plurality of detonators and a blaster during blasting.

[0002] Generally, explosives are used in construction projects such as rock blasting for tunnels or the demolition of abandoned buildings. Specifically, the target for blasting is divided into sections, and multiple holes are drilled into which explosives are inserted. After inserting explosives into each of the drilled holes, they are connected to a blasting system. The target is then blasted by detonating the explosives through the operation of the blasting system.

[0003] A blasting system is composed of a detonator, which acts as a trigger to detonate explosives, and a blasting device that transmits the power and commands necessary for the detonator's operation to the detonator. In this case, electric or electronic detonators are primarily used as the detonators in the blasting system. Electric or electronic detonators are installed on the explosive side, and multiple detonators are connected to a single blasting device.

[0004] Electric detonators or electronic detonators have a structure in which, when a command is transmitted from a blaster, multiple detonators connected to the blaster operate simultaneously to detonate explosives simultaneously, and a structure in which multiple electronic detonators are set with different delay times so that multiple detonators operate sequentially to detonate explosives sequentially.

[0005] The wires connected to electric or electronic detonators, or the busbars connected to blasters, have their insulation stripped from their ends for blasting operations and are used by connecting them to the busbars, wires, and auxiliary busbars of other electric or electronic detonators.

[0006] To prevent the connection point from being exposed to the outside when connecting the main line and the branch line, the main line and the branch line are connected using detonator connectors.

[0007]

[0008] When performing wiring work after loading a detonator into a blast hole during blasting operations, in the case of an electronic detonator, wiring work is performed on the trunk wire in the order of time setting.

[0009] In this case, there was a problem in that it was difficult and time-consuming to identify the target detonator's wire and connect it to the trunk wire, as it was necessary to locate the blast hole and find the wire of the detonator loaded in the blast hole, but there were many blast holes and the wire colors were often the same or similar after the charge was finished, and the wire itself was difficult to identify with the naked eye when the background rock color was bright.

[0010] A prior art patent related to the present invention is Korean Patent Registration No. 10-0424732, "Wire connector and busbar connector for electric detonator" (registered March 16, 2004).

[0011] The objective of the present invention is to provide a blasting wire connection structure that enhances the identification of wires during the wiring operation of connecting multiple wires to a main line by equipping each wire connecting multiple detonators and a blaster with a light-emitting function during blasting.

[0012] To achieve the above objectives, one embodiment of a blasting wire connection structure according to the present invention comprises a busbar electrically connected to a blasting machine, a wire connected to the busbar and electrically connected to a detonator, and a detonator connector electrically connecting the busbar and the wire, wherein the covering portion surrounding the core wire of the wire is a light-conducting covering portion capable of transmitting light, and further comprises a light source portion that causes light to be incident on the light-conducting covering portion.

[0014] In the present invention, the detonator connector includes a light-transmitting window that is positioned facing the end of each wire wired inside and through which light from a light source passes. The light source is positioned outside the detonator connector and transmits light into the connector housing through the light-transmitting window, thereby causing light to be incident on the end of each wire positioned facing the light-transmitting window.

[0015] In the present invention, the light-guiding coating may include a fluorescent material.

[0016] In the present invention, a plurality of the above-mentioned lines may have light having at least two colors, including a first-color line comprising a fluorescent material that emits light of a first color and a second-color line comprising a fluorescent material that emits light of a second color.

[0019] In the present invention, the light source operation control unit includes a switch capable of blocking the current or electrical signal applied to the wire connection terminal unit, so that when the light source unit emits light, the current or electrical signal applied to the wire connection terminal unit is blocked, and power supply to the light source unit is maintained to maintain the operating state of the light source unit.

[0020] In the present invention, the light source may include a lamp capable of selectively emitting light having a plurality of colors.

[0021] In the present invention, the light source operation control unit may include a color selection switch unit capable of selecting and emitting the color of light emitted from the lamp.

[0022] In the present invention, a plurality of light source operation control units provided in a plurality of detonator connectors each have a wireless communication unit, so that at least two of the closest light source operation control units among the plurality of light source operation control units can operate the light source unit by selecting a different color of light emitted from the light source unit through wireless communication with each other.

[0023] In the present invention, the light source is located at the end side of each wire inside the connector housing and can emit light toward the end side of each wire.

[0024] In the present invention, the light source part may be provided with a power supply terminal that is exposed to the outside of the connector housing part and electrically connected to a power supply part.

[0025] In the present invention, the light source unit is disposed within the detonator, and may be disposed to allow light to be incident on the end side of each wire connected to the detonator.

[0026]

[0053] FIGS. 1 and 2 are schematic diagrams illustrating an embodiment of a wire connection structure for blasting according to the present invention, and FIGS. 1 and 2 illustrate an embodiment in which a light source part (400) is provided in a connector (300) for a detonator.

[0054] One embodiment of the wire connection structure for blasting according to the present invention is a wire connection structure that connects a plurality of detonators (20) inserted into a plurality of blast holes drilled at a blasting site to a blasting machine (10) using a main line (100), a branch line (200), and a detonator connector (300).

[0055] An embodiment of a wire connection structure for blasting according to the present invention is described in detail below with reference to FIGS. 1 and 2.

[0056] One embodiment of a blasting wire connection structure according to the present invention includes a busbar (100) electrically connected to a blasting machine (10), individual wires (200) connected to the busbar (100) and electrically connected to a detonator (20), and a detonator connector (300) electrically connecting the busbar (100) and the individual wires (200).

[0057] The busbar (100) is electrically connected to the blaster (10), and the blaster (10) is equipped with a power supply control unit that supplies electric power through the busbar (100) to apply a blasting signal to the detonator (20).

[0058] At the blasting site, multiple blast holes are drilled, and a detonator (20) is inserted into each blast hole to detonate the explosives loaded into the blast hole.

[0059] Each wire (200) is provided in multiple numbers corresponding to the number of drilled blast holes to connect the detonator (20) inserted into the blast hole to the main wire (100), and the detonator connector (300) is also provided in multiple numbers corresponding to the number of drilled blast holes to connect the multiple wires (200) connected to the detonator (20) to the main wire (100).

[0060] Although the detonator (20) is not shown, it is exemplified as including an ignition device that receives a blasting signal from the blasting machine (10), a delay agent ignited by the ignition device, a pre-explosive, and a base charge, and can be implemented in various modified forms with known structures, so further detailed description is omitted.

[0061] The detonator connector (300) is openable and can be opened and closed, and includes a connector housing part (310) having a main line passing hole and a branch line passing hole on its outer surface, and a wire connection terminal part (320) located inside the connector housing part (310) to which the main line (100) and the branch line (200) are respectively connected.

[0062] The wire connection terminal (320) is manufactured of a conductive material capable of electrically connecting the busbar (100) and the wire (200) in a bracket structure comprising a busbar connection terminal (321) having a busbar insertion groove into which the busbar (100) is inserted and connected, and a wire connection terminal (322) having a wire insertion groove into which the wire (200) is inserted and connected.

[0063] It is noted that the terminal portion (320) for connecting wires is made of a conductive material such as copper, aluminum, or an alloy containing at least one of copper and aluminum, which has excellent conductivity, and can be made of any known material capable of electrically connecting the busbar (100) and the wire (200).

[0064] And, the terminal part (321) for connecting the busbar has a structure in which, when the busbar (100) is inserted into the busbar fitting groove, the sheath is cut or peeled off, exposing the inner core wire, and the exposed core wire is connected.

[0065] Additionally, the terminal portion (322) for connecting each wire has a structure in which, when each wire (200) is inserted into the wire fitting groove, the sheath is cut or peeled off, exposing the inner core wire, and the exposed core wire is connected.

[0066] The connector housing (310) has a first busbar passage hole located on one side and a second busbar passage hole provided on the other side facing the one side so that the busbar (100) can be wired by passing through both sides.

[0067] More specifically, the wire connection terminal part (320) is located on one side of the connector housing part (310) and includes a first busbar connection terminal part (321a) having a first busbar insertion groove into which one of the two core wires from the busbar (100) is inserted and connected, and a first busbar passing groove through which the other core wire passes without being connected, and a second busbar connection terminal part (321b) located on the other side of the connector housing part (310) facing the first busbar connection terminal part (321a) and having a first busbar insertion groove into which the other of the two core wires from the busbar (100) is inserted and connected, and a second busbar passing groove through which one of the core wires passes without being connected.

[0068] Additionally, the wire connection terminal part (320) is located inside the connector housing part (310) and includes a first wire connection terminal part (322a) having a first wire insertion groove into which one of the two core wires of the wire (200) is inserted and connected, and a first wire passing groove into which the other core wire passes without being connected, and a second wire connection terminal part (322b) located facing the first wire connection terminal part and having a first wire insertion groove into which the other of the two core wires is inserted and connected, and a second wire passing groove into which one of the core wires passes without being connected.

[0069] The busbar (100) passes through the connector housing part (310) through the first busbar passing hole and the second busbar passing hole, and at this time, one of the two core wires is inserted into the first busbar insertion groove of the first busbar connection terminal part (321a), and the other of the two core wires is inserted into the second busbar insertion groove of the second busbar connection terminal part (321b) and is electrically connected, that is, connected to the wire connection terminal part (320).

[0070] Additionally, each wire (200) is positioned such that a portion of its end side is inserted into the interior of the connector housing (310) through the wire passing hole, and at this time, one of the two core wires is inserted into the first wire fitting groove of the first wire connection terminal part (322a), and the other of the two core wires is inserted into the second wire fitting groove of the second wire connection terminal part (322b) and is electrically connected, i.e., connected, to the wire connection terminal part (320).

[0071] Accordingly, the main line (100) and the individual lines (200) can be electrically connected to each other through the wire connection terminal (320).

[0072] And, each wire (200) includes two core wires and a covering that wraps the two core wires, and the covering is a light-conducting covering that can transmit light.

[0073] It should be noted that further detailed explanations are omitted, citing as an example that the light-guiding coating comprises a known light-transmitting material or is manufactured from a known light-transmitting material that transmits incident light.

[0074] In addition, the light guide covering may include various known fluorescent materials that include a fluorescent material to emit light in a preset color upon incident light.

[0075] Fluorescent materials play a role in increasing the intensity of light emitted through the light guide covering or in emitting light of a specific color through the light guide covering.

[0076] A plurality of each line (200) may each emit light of a different color by including a fluorescent material that emits light of a different color.

[0077] In addition, a plurality of lines (200) are given as an example of having light having at least two colors, including a first color line containing a fluorescent material that emits light of a first color and a second color line containing a fluorescent material that emits light of a second color.

[0078] Each line (200) includes a color indicator that displays the color of the emitted light, allowing the worker to check the color of the emitted light, and the worker can select and use a line (200) that emits light of the desired color during work.

[0079] Multiple wires (200) connected to multiple detonators (20) are arranged such that the color of the light emitted from the wires (200) closest to each other is different, thereby improving identification during wiring work and increasing work convenience.

[0080] A plurality of wires (200) connected to a plurality of detonators (20) are wired with fluorescent materials having different colors, and at least two wires (200) closest to each other are wired with fluorescent materials having different colors so as not to cause confusion when adjacent wires (200) emit the same color, and can more clearly distinguish adjacent wires (200) to improve identification during wiring work and greatly increase work convenience.

[0081]

[0082] Meanwhile, one embodiment of the blasting wire connection structure according to the present invention further includes a light source part (400) that transmits light to a light guide covering part, and the light guide covering part emits light while transmitting the light transmitted through the light source part (400).

[0083] The light source (400) is exemplified as an LED (light emitting diode), but can also be used as various known light sources capable of emitting light by causing light to be incident into the light guide covering.

[0084] It is noted that the light source unit (400) is provided by being mounted on the detonator connector (300) as an example, and may also be provided separately from the detonator connector (300).

[0085] As an example, the light source (400) is mounted on the detonator connector (300) and positioned facing the end of each wire (200) connected to the wire connection terminal (320) to cause light to be incident on the end of each wire (200).

[0086] The detonator connector (300) includes a light-transmitting window (311) positioned facing the end of each wire (200) wired inside, through which light from a light source (400) passes. As an example, the light source (400) is positioned outside the detonator connector (300) and transmits light into the connector housing (310) through the light-transmitting window (311) to cause light to be incident on the end of each wire (200) positioned facing the light-transmitting window (311).

[0087] It is noted that the light source unit (400) may be electrically connected to a wire connection terminal unit (320) to emit light, and may be operated by receiving power from the blasting machine (10) after the busbar (100) is connected to the wire connection terminal unit (320).

[0088]

[0089] Meanwhile, referring to FIG. 2, one embodiment of the blasting wire connection structure according to the present invention further includes a light source operation control unit (500) that is electrically connected to a wire connection terminal (320) and a light source unit (400), and supplies power to the light source unit (400) to emit light through the light source unit (400) when each wire (200) and the busbar (100) are each normally connected to the wire connection terminal (320).

[0090] The light source operation control unit (500) applies a current or electrical signal to the wire connection terminal unit (320) that prevents the detonator (20) from operating when the power supply through the blaster (10) is cut off, and checks whether each wire (200) and the busbar (100) are properly connected to the wire connection terminal unit (320).

[0091] The light source operation control unit (500) applies current to the wire connection terminal (320) and measures the resistance value to check whether each wire (200) and the busbar (100) are properly connected to the wire connection terminal (320), as an example. In addition, it is noted that the light source operation control unit (500) can be implemented in various modified forms using known detection structures that can check whether each wire (200) and the busbar (100) are properly connected to the wire connection terminal (320) through an electrical signal.

[0092] When the light source operation control unit (500) confirms that each wire (200) and the busbar (100) are each properly connected to the wire connection terminal unit (320), it supplies power to the light source unit (400) to emit light through the light source unit (400) and causes the light to be incident on the end side of each wire (200).

[0093] And, if each wire (200) and the busbar (100) are not properly connected to the wire connection terminal (320) respectively, power is not supplied to the light source (400).

[0094] Accordingly, the light-guiding covering of each wire (200) emits light only when each wire (200) and the main wire (100) are properly connected to the wire connection terminal (320), and the operator can simply check whether each wire (200) and the main wire (100) are properly connected by checking the light-emitting state of each wire (200).

[0095] Additionally, the light source operation control unit (500) includes a switch capable of blocking the current or electrical signal applied to the wire connection terminal unit (320). When the light source unit (400) emits light, that is, when it is confirmed that each wire (200) and the busbar (100) are each normally connected to the wire connection terminal unit (320), the current or electrical signal applied to the wire connection terminal unit (320) is blocked, and power supply to the light source unit (400) is maintained to maintain the operating state of the light source unit (400).

[0096] The light source operation control unit (500) blocks the current or electrical signal applied to the wire connection terminal unit (320) while maintaining power supply to the light source unit (400), so that the blasting signal, i.e., the current, transmitted from the blasting machine (10) to the detonator (20) can be transmitted normally.

[0097]

[0098] The light source unit (400) includes a lamp capable of selectively emitting light of multiple colors, and is exemplified by including an LED lamp capable of emitting blue, red, and white light.

[0099] In addition, the light source operation control unit (500) includes a color selection switch unit that can select and emit the color of light emitted from the lamp, so that the operator can select and emit the color of the light.

[0100] Accordingly, the operator can select to emit light of the desired color when working on each line (200) through the color selection switch.

[0101] When performing wiring work to connect each wire (200) to the main wire (100), the worker can operate the color selection switch provided in the detonator connector (300) to select a different color of light for the two wires (200) closest to each other among the multiple wires (200) connected to the multiple detonators (20), thereby improving identification ability during wiring work and increasing work convenience.

[0102] In addition, a plurality of light source operation control units (500) provided in a plurality of detonator connectors (300) each have a wireless communication unit, and at least two of the closest light source operation control units (500) among the plurality of light source operation control units (500) operate the light source unit (400) by selecting a different color of light emitted from the light source unit (400) through wireless communication with each other.

[0103] The light source operation control unit (500) can increase work convenience by selecting the light emission color of the light source unit (400) such that the light emitted for the two closest wires (200) among the multiple wires (200) connected to the multiple detonators (20) is different, thereby improving identification during wiring work.

[0104]

[0105] FIG. 3 is a schematic diagram illustrating another embodiment of a wire connection structure for blasting according to the present invention. Referring to FIG. 3, the light source part (400) is located at the end side of each wire (200) inside the connector (300) for detonators, that is, inside the connector housing part (310), and emits light toward the end side of each wire (200) so that the light is incident on the end side of each wire (200) and the light guide covering part of each wire (200) may be illuminated.

[0106] The light source part (400) is, for example, an LED lamp and is provided with a power supply terminal (400a) that is exposed to the outside of the connector housing part (310) and electrically connected to the power supply part.

[0107] The light source unit (400) is exemplified as including a plurality of LED lamps, and some of the plurality of LED lamps and the remainder of the plurality of LED lamps are arranged in different polarity directions so that when a power supply socket is connected to a power supply terminal (400a), at least a portion of the plurality of LED lamps can emit light regardless of the direction of the power supply socket.

[0108] For example, the light source unit (400) is equipped with an even number of LED lamps, and when connected in a non-directional socket connection structure with half of the LED lamps arranged with different polarities, half of the LED lamps among the plurality of LED lamps can stably emit light and cause light to be incident on the end of each wire (200).

[0109] That is, the light source unit (400) is connected to the power supply unit with a non-directional socket connection structure, and the plurality of LED lamps are separated into two groups with different polarities to ensure convenience during connection and to stably induce light on the end side of each wire (200).

[0110]

[0111] Meanwhile, FIG. 4 is a schematic diagram illustrating another embodiment of a wire connection structure for blasting according to the present invention. Referring to FIG. 4, the light source unit (400) is positioned within the detonator (20), and is positioned so as to allow light to be incident on the end side of each wire (200) connected to the detonator (20).

[0112] As an example, the light source unit (400) is positioned facing the end of the wire (200) to which the wire (200) is connected within the detonator (20), and includes a battery and an operating switch so that the light source unit can be turned on and off by operating the operating switch when the detonator (20) is installed.

[0113] The light source unit (400) is activated when the detonator (20) connected to each wire (200) is inserted into the blast hole, emitting light so that the light is incident on the end side of each wire (200) and the light is emitted through the light guide covering of each wire (200), thereby increasing the visibility of each wire (200) during the connection work of connecting a plurality of wires (200) to the main wire (100).

[0114]

[0115] Meanwhile, FIG. 5 is a schematic diagram illustrating another embodiment of a wire connection structure for blasting according to the present invention, and illustrates an example in which each wire (200) emits light through electroluminescence (EL) without a light source.

[0116] Accordingly, another embodiment of the blasting wire connection structure according to the present invention comprises a busbar (100) electrically connected to a blaster (10), a wire (200) connected to the busbar (100) and electrically connected to a detonator (20), and a detonator connector (300) electrically connecting the busbar (100) and the wire (200).

[0117] It should be noted that an embodiment of the detonator connector (300) can be implemented in the same manner as the embodiment mentioned in one embodiment of the blasting wire connection structure according to the present invention, so a more detailed description is omitted.

[0118] The blasting device (10) includes a blasting power control unit that applies a detonation signal, i.e., current, to each detonator (20) through a busbar (100), and the blasting power control unit includes an AC power application unit (600) that applies AC power to the busbar (100) to cause the EL (Electro Luminescence, EL) covering (230) of each wire (200) to emit light, and a DC power application unit (700) that applies DC power to the busbar (100) for transmitting a blasting signal.

[0119] Another embodiment of the blasting wire connection structure according to the present invention further includes an AC power blocking unit (800) located within a detonator (20), to which each wire (200) is connected, which blocks the application of AC power into the ignition device of the detonator (20) and transmits only DC power to the ignition device.

[0120] That is, another embodiment of the blasting wire connection structure according to the present invention includes an AC power supply unit (600) that is included in the blasting power control unit of the blasting machine (10) and applies AC power to the busbar (100) to cause the EL (Electro Luminescence, EL) covering (230) of each wire (200) to emit light, a DC power supply unit (700) that applies DC power to the busbar (100) for transmitting a blasting signal, and an AC power cutoff unit (800) that is located within the detonator (20), to which each wire (200) is connected, blocks the application of AC power into the ignition device of the detonator (20), and passes only DC power to transmit to the ignition device.
