Description

Technical Field

[0001] This invention relates to a power distribution cable operation display device in a residential building. The device displays the open state when the cable is moved by sliding, and simultaneously displays the energized state of the power distribution cable. When exposed to the outside, it displays the closed state, and simultaneously displays the de-energized state of the power distribution cable, so as to accurately inform the staff of the energized or de-energized status of the power distribution cable. Background Technology

[0002] Normally, a switch for power distribution cables is installed on the power distribution cable to cut off or supply power.

[0003] The switch for the power distribution cable has a switching device installed between the lead wires. The switch provides power or disconnects power according to the operation of the switching device. It is usually installed on the utility pole where the power distribution cable is laid.

[0004] In addition, in order to inform the management personnel (operators) of the operating status (closed, open) of the power distribution cable switch and prevent safety accidents from occurring, an operating status indicator device for the power distribution cable switch is also provided.

[0005] As a patent document demonstrating the operational status of a switch for power distribution cables, Utility Model Registration No. 20-0298407 describes a method of indicating whether a power distribution cable switch is on or off by affixing luminous paint or stickers to a status indicator plate. This allows for confirmation of the switch's on / off status in dark environments or day and night. The indicator displays the switch's energized or de-energized state based on the switch's operation, the force applied to the switch's opening degree, and its orientation. The method also indicates the switch's energized or de-energized state by pointing to a specific area.

[0006] In conventional technologies such as the aforementioned patent documents, the closing and opening statements are attached to the switch of the power distribution cable and kept in a fixed state. Indicating means such as an indicator needle point to or block either of the notification statements. In this way, two notification statements are often displayed: the closing statement and the opening statement. Therefore, if the indicating means malfunctions, there is a problem that the correct operating state cannot be displayed.

[0007] Therefore, it is necessary not only to selectively display close and open statements, but also to have equipment that can accurately display the energized or de-energized status of power distribution cables. Summary of the Invention

[0008] The problem that the invention aims to solve

[0009] In various embodiments of the present invention, first and second indicator plates, displaying an open mark and a closed / closed mark to be extracted or introduced, are formed at a pair of first and second openings on the upper and lower surfaces of the display housing. Third and fourth indicator plates, displaying an open mark to be extracted or introduced based on sliding movement, are formed at third and fourth openings on both sides of the display housing. These constitute the first and second signs. When the power cable is not energized, the first and second signs are exposed to the outside, informing the worker that the power cable is not energized. When the power cable is energized, it slides and moves, exposing the open mark to the outside while simultaneously allowing withdrawals at the pair of first and second openings on the upper and lower surfaces of the indicator housing. At the same time, the third and fourth signs formed on both sides of the indicator housing move towards the worker and slide when the worker is engaged, thus informing them of the energized status.

[0010] Therefore, the first, second, third and fourth signs are intended to provide staff with indication devices for the operation of power distribution cables within the residential community, so as to accurately indicate whether the power distribution cables are energized or de-energized.

[0011] means for solving problems

[0012] According to various embodiments of the present invention, a power distribution cable operation display device in a residential building is a display housing located on the switch side of the power distribution cable, the switch being placed on the power distribution cable connected by an insulator; a pair of first and second openings are formed on the upper and lower surfaces of the housing, and a third and fourth opening are formed on both sides of the housing; a first and second indicator plate is formed at the pair of first and second openings, and is slidably movable according to the drive of a drive motor, forming an open mark and a closed / closed mark extracted or introduced at the pair of first and second openings; and is slidably movable at the third and fourth openings, and is slidably movable according to the drive motor. Driven by sliding movement, the third and fourth indicator plates are extracted or introduced from the third and fourth openings to form open markings. This includes the first and second labels, when the power distribution cable is not energized, exposing the closed / closed markings to the outside, informing workers that the power distribution cable is not energized; the first and second labels slide when the power distribution cable is energized, removing them from the pair of first and second openings and exposing the open markings to the outside, while simultaneously sliding the third, fourth, and fourth labels at the third, fourth, and fourth openings to notify workers of the operating status; the operating status can be slid when energized.

[0013] According to various embodiments of the present invention, a first marker moving part is further included, which is arranged on the side of the first and second indicator plates and at the pair of first and second openings, for extracting the first and second indicator plates, and slides vertically upward and downward. The first marker moving part is arranged on the side of the first and second indicator plates and corresponds to the rotation of the drive motor. The first and second marker moving parts are gears that rotate according to the gears. An on / off switch is included, which adds an on (open) or off (close) signal to the processor according to the energized or de-energized state of the power distribution cable. A processor is included, which controls the drive motor according to the on or off signal of the on / off switch that is electrically connected to and acknowledges the on / off switch.

[0014] The following components are included: a second indicator moving part that slides horizontally to the left and right, positioned on the side of the third and fourth indicator plates and meshing with a rotating gear on the drive motor, and sliding according to the rotation of the rotating gear; an on / off switch that grants an on (open) or off (close) signal to the processor according to the energized or de-energized state of the power distribution cable; and a processor that controls the drive motor to drive according to the on or off signal of the on / off switch that is electrically connected to and acknowledges the on / off switch.

[0015] According to various embodiments of the present invention, one end of the first and second signs may be formed as an anti-detachment member to prevent the first and second signs from detaching from the pair of first and second openings and to limit the sliding movement of the first and second signs.

[0016] Invention Effects

[0017] According to various embodiments of the present invention, first and second indicator plates with open or closed / closed markings are formed at a pair of first and second openings formed on the upper and lower surfaces of the display housing, and third and fourth indicator plates with open or closed markings that can be slidably moved are formed at third and fourth openings formed on both sides of the display housing. By configuration, the closed / closed markings of the power distribution cable of the first and second plates are exposed to the outside when the power distribution cable is not energized, accurately informing the operator that the power distribution cable is not energized. In this state, the operator is not at risk of electric shock, and can not only safely perform maintenance work on the switch for the power distribution cable, but also safely replace the power distribution cable.

[0018] Additionally, the first and second indicator signs refer to the sliding movement of the power distribution cable when energized, removing it from a pair of first and second openings formed on the upper and lower surfaces of the display housing, simultaneously exposing the open mark to the outside. Simultaneously, the third and fourth indicator signs slide and are removed from the third and fourth openings formed on both sides of the housing, exposing the open mark to the outside. This displays the open status and the status of the operator, informing them of the electrical status. Furthermore, workers are prohibited from performing maintenance work on the power distribution cable switch or replacing the power distribution cable due to the risk of electric shock.

[0019] Therefore, the first, second, third, and fourth signs, through their exposed closed / closed, open, and open markings, can accurately inform operators whether the power distribution cable is energized or not, thus preventing potential problems. Attached Figure Description

[0045] According to various embodiments of the present invention, a power distribution cable operation indicator 100 in a residential building can expose the closed / closed markings formed on the first and second labels 120 and 130 when the power distribution cable 11 of the power distribution cable switch 10 is not energized, accurately informing workers that the power distribution cable is in a de-energized state. When the power distribution cable 11 is energized, it slides on the label 150 forming an open indicator light 150 on the first and second labels 130 and moves on an external labeling plate, thereby simultaneously displaying the label 150 on label 120. The exposure can be achieved through one or more combinations of various devices to accurately notify workers that the power distribution cable 11 is energized.

Figure 8 This is a partial cut-out front view reflecting the working state of the power distribution cable operation indicator 100 in a residential building according to various embodiments of the present invention. Figure 9 This is a diagram showing the operating state of the residential power distribution cable operation indicator 100 in the third and fourth versions 140 of various embodiments of the present invention. The 10 examples of residential power distribution cable operation diagrams are based on version 100 of the present invention. This is a front view reflecting the operating state of the third and fourth indicator plates 140 and 150 in the configuration.

[0047] like Figure 1 or Figure 10 As shown, a power distribution cable operation indicator 100 in a residential building may include a power distribution cable switch 10, a display housing 110, first, second, third and fourth indicator plates 120, 130, 140 and 150, and first and second indicator moving parts 160 and 170. For example, the power distribution cable switch 10 may be connected to the power distribution cable 11 and the insulator 12.

[0048] The display housing 110 can be placed on one side of the switch 10 for the power distribution cable. For example, a pair of first openings 111 may be formed on the upper surface of the marking housing 110 to allow the first and second marking plates 120 and 130, described later, to be extracted or introduced by sliding movement.

[0049] A pair of second openings 112 can be formed on the lower surface of the marking housing 110 to allow the first and second marking plates 120 and 130, described later, to be slidably moved out or introduced.

[0050] On both sides of the marking housing 110, third and fourth openings 113 and 114 can be formed to allow the third and fourth indicator plates 140 and 150 (described later) to be extracted or introduced by sliding movement. For example, the third opening 113 can be formed on one side of the marking housing 110 (e.g., the left side). The fourth opening 114 can be formed on the other side of the marking housing 110 (e.g., the right side).

[0051] The first and second labels 120 and 130 can slide and move in conjunction with the pair of first and second openings 111 and 112. For example, the first and second labels 120 and 130 can slide and move according to the drive of the drive motor 190 described later, and be extracted or imported from the pair of first and second openings 111 and 112. The first and second labels 120 and 130 can form open and closed / closed markings.

[0052] The third and fourth labels 140 and 150 can slide and move in conjunction with the third and fourth openings 113 and 114. For example, the third and fourth labels 140 and 150 can slide and move according to the drive of the drive motor 190, and can be removed or taken out from the third and fourth openings 113 and 114. The third and fourth labels 140 and 150 can form an open mark.

[0053] When the power distribution cable 11 of the power distribution cable switch 10 is energized, the first and second labels 120 and 130 expose the switch off / off markings externally, informing the operator that the power distribution cable 11 is energized. At this time, the operator realizes that the power distribution cable 11 is de-energized, allowing for safe maintenance of the power distribution cable switch 10 and safe replacement of the power distribution cable 11.

[0054] The first and second signs 120 and 130 are slidably moved by the power distribution cable 11 when it is energized, and are taken out from the pair of first and second openings 111 and 112. At the same time, the third and fourth signs 140 and 150 are slidably moved out from the third and fourth openings 113 and 114, so that the open signs can be exposed.

[0055] At this time, staff can check the open markings of the first and second signs 120 and 130, and the third and fourth signs 140 and 150, to understand the energization status of the power distribution cable 11. Therefore, staff can see that the power distribution cable 11 is powered. Furthermore, staff can see that each household in the residential complex has power.

[0056] The first marker moving part 160 can be placed on the side of the first and second marker plates 120 and 130. For example, the first marker moving part 160 can slide in the vertical up and down direction to extract the first and second marker plates 120 and 130 from the pair of first and second openings 111 and 112.

[0057] The first marker moving element 160 may include first and second rack-mounted gears 161 and 162, an on / off switch A1, and a processor B1. For example, the first rack-mounted gear 161 may be positioned on the side of the first indicator plate 120. The second rack-mounted gear 162 may be positioned on the side of the second indicator plate 130.

[0058] The first and second frame gears 161 and 162 can be arranged facing each other while being arranged in a row at a certain distance to accommodate the drive motor described later.

[0059] A drive motor 190 can be placed between the first and second frame gears 161 and 162.

[0060] For example, the first and second frame gears 161 and 162 mesh with the rotary gear 191 on the drive motor 190, and can slide in the vertical up and down directions according to the rotation of the rotary gear 191.

[0061] At this time, if the first and second frame gears 161 and 162 slide in the vertical up and down directions, the first and second signs 120 and 130 can also slide and move together.

[0062] For example, if the rotating gear 191 is driven to rotate by the drive motor 190, the first frame gear 161 can slide in the vertical upward direction, and the second frame gear 162 can slide in the vertical downward direction.

[0063] Therefore, the first indicator plate 120 can slide in the vertical upward direction, and the second indicator plate 130 can slide in the vertical downward direction.

[0064] The on / off switch A1 can authorize the processor B1 to issue an on-off or off signal based on the energization status of the power distribution cable 11. For example, when the power distribution cable 11 is energized, the on / off switch A1 can authenticate an on signal to the processor B1.

[0065] Furthermore, the on / off switch A1 can send a shutdown signal to the processor B1 when the power distribution cable is not energized.

[0066] The processor B1 can be electrically connected to the on / off switch A1 and control the drive motor 190 according to the on (open) or off (close) signal of the on / off switch A1.

[0067] At this time, the processor (B1) can drive the drive motor 190 based on the open signal of the open / close switch A1, and at the same time rotate the gear 191 to make the first and second indicator plates 120 and 130 slide vertically up and down.

[0068] Furthermore, at one end of the first and second signs 120 and 130, while preventing the first and second signs 120 and 130 from detaching from the pair of first and second openings 111 and 112, an anti-detachment member 180 may be formed to restrict the sliding of the first and second signs 120 and 130. For example, if the first and second signs 120 and 130 slide into the first and second openings 111 and 112 and are inserted, the anti-detachment member 180 may contact the first and second openings 111 and 112, restricting the sliding of the first and second signs 120 and 130 while preventing them from detaching from the first and second openings 111 and 112.

[0069] Furthermore, the second marker moving part 170 can be placed on the side of the third and fourth marker plates 140 and 150. For example, the second marker moving part 170 can slide horizontally to the left and right to extract the third and fourth marker plates 140 and 150 from the third and fourth openings 113 and 114.

[0070] The second marker moving element 170 may include third and fourth rack-mounted gears 171 and 172, an on / off switch A1, and a processor B1. For example, the third rack-mounted gear 171 may be positioned on the side of the third indicator plate 140. The fourth rack-mounted gear 172 may be positioned on the side of the fourth indicator plate 150.

[0071] The third and fourth frame gears 171 and 172 can be arranged facing each other, while the drive motor 190 can be arranged at a certain distance apart.

[0072] A drive motor 190 can be placed between the gears 171 and 172 of the third and fourth frames.

[0073] For example, the third and fourth frame gears 171 and 172 mesh with the rotary gear 191 on the drive motor 190, and can slide in the horizontal left and right directions according to the rotation of the rotary gear 191.

[0074] At this time, if the third and fourth frame gears 171 and 172 slide in the horizontal left and right directions, the third and fourth indicator plates 140 and 150 can also slide and move together.

[0075] For example, if the rotating gear 191 is driven to rotate by the drive motor 190, the third frame gear 171 can slide to the left in the horizontal direction, and the fourth frame gear 172 can slide to the right in the horizontal direction.

[0076] Therefore, the third sign 140 can slide to the left in the horizontal direction, and the fourth sign 150 can slide to the left in the horizontal direction.

[0077] The on / off switch A1 can authorize the processor B1 to issue an on-off or off signal based on the energization status of the power distribution cable 11. For example, when the power distribution cable 11 is energized, the on / off switch A1 can authorize the processors B1 and C1 to issue an on signal.

[0078] Furthermore, the on / off switch A1 can send a shutdown signal to the processor B1 when the power distribution cable 11 is not energized.

[0079] The processor B1 can be electrically connected to the on / off switch A1 and control the drive motor 190 according to the on (open) or off (close) signal of the on / off switch A1.

[0080] At this time, the processor B1 can drive the drive motor 190 according to the open signal of the open / close switch A1, and at the same time rotate the gear 191 to make the third and fourth indicator plates 140 and 150 slide horizontally to the left and right.

[0081] In this state, when the power distribution cable 11 of the power distribution cable switch 10 is energized, the switch A1 authorizes the switch (closed) signal to the processor B1, and the processor B1 will not drive the drive motor 190 based on the switch (closed) signal of the switch A1.

[0082] If the drive motor 190 is not driven, the off / off markings formed on the first and second indicator plates 120 and 130 may be exposed to the outside.

[0083] At this point, staff can realize that the first and second signs 120 and 130 are closed / closed, indicating that the power distribution cable 11 is not currently receiving power.

[0084] Workers can accurately detect when the power distribution cable 11 is not supplying power and safely perform maintenance and replace the power distribution cable 11.

[0085] Furthermore, when the power distribution cable 11 of the power distribution cable switch 10 is energized, the open / close switch A1 can send an open signal to the processor B1, and the processor B1 can drive the drive motor 190 according to the open signal of the open / close switch A1.

[0086] The drive motor 190 can drive the rotating gear 191.

[0087] The rotating gear 191 can slide the first and second frame gears 161 and 162 according to rotation.

[0088] In other words, the first frame gear 161 can slide in the vertical upward direction. At this time, together with the first frame gear 161, the first indicator plate 120 can also slide in the vertical upward direction.

[0089] The first sign 120 can be extracted from the pair of first openings 111 while it is sliding.

[0090] At the same time, the second frame gear 162 can slide in the vertical downward direction. Simultaneously, the second indicator plate 130 can also slide in the vertical downward direction along with the second frame gear 162.

[0091] The second sign 130 can be extracted from the pair of second openings 112 while sliding.

[0092] At this time, the open markings formed on the first and second signs 120 and 130 may be exposed to the outside. At the same time, the closed / closed markings formed on the first and second signs 120 and 130 may be introduced into the interior of the sign housing 110 and not exposed to the outside.

[0093] Meanwhile, driven by the drive motor 190, the third and fourth indicator plates 140 and 150 may slide and be removed from the third and fourth openings 113 and 114, and be exposed to the outside.

[0094] At this time, the opening marks formed on the third and fourth labels 140 and 150 may be exposed to the outside.

[0095] Staff can see the open markings of the first and second signs 120 and 130 and the third and fourth signs 140 and 150, and accurately know that the power distribution cable 11 is supplying power.

[0096] Similarly, when the power distribution cable 11 is energized, the closed / closed markings formed on the first and second labels 120 and 130 are exposed to the outside, accurately informing the staff that the power distribution cable 11 is energized. At this time, the staff do not need to be at risk of electric shock and can safely carry out maintenance work on the switch 10 for the power distribution cable and replace the power distribution cable 11.

[0097] Furthermore, when the power distribution cable 11 is extended, as the first and second indicator plates 120 and 130 slide and are removed from the upper and lower surfaces of the display housing 110, the open marks formed on the first and second indicator plates 120 and 130 will be exposed to the outside. Simultaneously, the third and fourth indicator plates 140 and 150 will move to the left and right directions of the display housing 110, and the energized working state 150 formed on the third and fourth indicator plates 150 can be correctly perceived. Therefore, workers may suffer electric shock accidents, and thus the switch 10 of the power distribution cable will not be repaired or the power distribution cable 11 replaced.

[0098] The various embodiments of the present invention described above regarding the operation display device for power distribution cables in residential buildings are not limited to the foregoing embodiments and drawings. Various substitutions, modifications, and alterations can be made within the technical scope of the present invention, which will be obvious to those skilled in the art to which the present invention pertains.
