Abstract

<P>PROBLEM TO BE SOLVED: To provide a breakage detection device for a shut-off bar capable of surely detecting the breakage of the shut-off bar even under the influence of wind. <P>SOLUTION: Since a conductive member 3 is provided along the longitudinal direction of the shut-off bar 1, and any of the current, voltage, or electric power consumption flowing to the conductive member 3 is detected by a detection means 5, the conductive member 3 is broken when breakage is generated in any part of the shut-off bar 1, the change of any of the current, the voltage, or the electric power consumption is detected, and the breakage of the shut-off bar 1 can be surely detected. Furthermore, if the conductive member 3 is formed by connecting a plurality of conductive units 2 wherein at least two electric conductors 21 are provided in parallel in the longitudinal direction, the conductive unit 2 except the one which is broken accompanied by the breakage of the shut-off bar 1 can be reutilized. <P>COPYRIGHT: (C)2007,JPO&INPIT

Description

  TECHNICAL FIELD The present invention relates to a breakage detecting device for a breaker that can be detected when a breaker provided at a doorway of a parking lot, a railroad crossing, or the like and provided in a breaker that blocks a vehicle is broken. It is.

Accidents that break off the barrier when the vehicle passes through a barrier that is installed at the entrance of a parking lot or at a railroad crossing, etc., and has a barrier that blocks the passage of the vehicle. There are not a few occurrences. In many cases, the breakage of the breaker is currently reported to the administrator of the breaker from the driver or passerby of the vehicle or train. For example, Patent Document 1 discloses a breakage of the breaker. It has been proposed to use a breakage detection device that detects the situation to contact the administrator of the circuit breaker.
That is, the breakage detection device for the breaker includes an infrared emitting part that emits infrared rays, an infrared reflection part of the breaker, a breakage breakage detection part that receives reflected infrared rays to detect the presence of breakage, This is configured by combining a power supply output unit for detection that outputs electric power to the power supply circuit based on the above signal, and automatically sends a breakage signal of the breaker to the administrator of the breaker.

Japanese Utility Model Publication No. 7-40350

  However, in the breaker detection device for the breaker as described above, when the breaker is shaken by a wind in a stormy weather or a wind generated by the passing of the vehicle, the infrared reflecting portion of the breaker is displaced from the infrared irradiation position. Although the breaker is not broken, it may be erroneously detected as broken.

  Accordingly, the present invention is intended to solve the above-described problems and provide a breaker detection device for a breaker that can reliably detect breakage of the breaker even under the influence of wind.

In order to achieve the above object, the present invention is configured as follows.
That is, the breakage detection device for a breaking rod according to the present invention includes a conductive member provided along a longitudinal direction of the breaking rod, a power consumer connected to the conductive member, and a power supply device that supplies power to the conductive member. Detecting means for detecting any of the current, voltage or power consumption flowing through the conductive member by the power supply device, and when the breaker breaks, depending on any change in the current, voltage or power consumption flowing through the conductive member The breakage of the barrier rod can be detected.

  According to the present invention, the conductive member is provided along the longitudinal direction of the barrier rod, and any one of the current, voltage, or power consumption flowing through the conductive member is detected by the detecting means, so that any portion of the barrier rod is broken. Even if this occurs, the conductive member is broken, and any change in current, voltage, or power consumption is detected, and breakage of the breaker can be reliably detected.

  In the present invention, the conductive member may be formed by connecting a plurality of conductive units in which at least two conductors are provided in parallel in the longitudinal direction. By doing so, it is possible to reuse a conductive unit other than the one broken with the breakage of the barrier rod. Furthermore, by changing the number of conductive units to be connected, it is preferable that the breakage detecting device can be easily formed corresponding to the blocking rods having different lengths.

Embodiments according to the present invention will be specifically described below with reference to the drawings.
That is, FIG. 1 is an explanatory view showing an embodiment of a breaker detecting device for a breaking rod according to the present invention.

  Reference numeral 1 is a long hollow barrier rod attached to the circuit breaker, and 2 is a conductive unit provided with two conductors 21 in parallel in the longitudinal direction. Two connection portions 22 are formed, and the connection portions 22 are electrically connected to each other so as to maintain a predetermined strength. A plurality of conductive units 2 are connected in the longitudinal direction to form a conductive member 3.

  Then, the conductive member 3 is inserted into the long hollow barrier rod 1, and both ends of the conductive member 3 are fixed to the base end portion and the distal end portion of the barrier rod 1, so that the base end portion of the barrier rod 1 is removed. A conductive member 3 is disposed over the tip. Further, the power consumer 4 is connected to the conductor 21 on the most advanced side of the barrier 1 and the conductor 21 on the most proximal side of the barrier 1 is connected to the detecting means 5 for detecting breakage of the barrier 1 and is detected. A power supply device 6 is connected to the means 5 to constitute a breakage detection device for the barrier 1.

  The conductive unit 2 preferably follows the deformation behavior of the barrier rod 1 when an external force such as a collision of the vehicle is applied, and if the barrier rod 1 breaks, the conductive unit 2 also breaks in the same manner. In addition, a laminate made of an epoxy resin and a glass fiber used for a general electronic substrate is preferably used, and the shape thereof is also formed in a long rod shape or a flat plate shape.

  As a material of the conductor 21, a conductive paint or conductive resin film mixed with metal powder, a metal foil or wire such as aluminum or copper, etc. are used, and these are appropriately applied, printed, adhered or by an attachment member. The conductor 21 may be formed by fixing or the like. In short, it is only necessary to be formed of a conductive material having such a strength that the conductor 21 is cut when an external force such as a vehicle collision acts and the conductive unit 2 breaks due to breakage of the barrier 1.

  The connecting portion 22 is not particularly limited as long as it electrically connects the adjacent conductive units 2 and connects the adjacent conductive units 2 with a predetermined strength as described above. In consideration of workability at the time of connection, it is preferable to use a connector having a concavo-convex structure generally used for connection of electric wiring.

  When the blocking rod 1 is broken, the conductive unit 2 that forms the inserted conductive member 3 is also broken. As described above, the conductive unit 2 is connected to each other at the connection portions 22 formed at both ends thereof. Therefore, the conductive unit 2 that is not broken can be separated and reused. If the length of the conductive unit 2 is too short, the connection takes time, and if it is too long, the portion that cannot be reused at the time of breakage increases.

  The power consuming body 4 may be anything that consumes power, and may be simply formed by connecting an electrical resistor to the conductor 21. However, the light emitting body including a light emitting diode or the like is directed toward the vehicle driver. If the electric power consumer 4 is configured on the outer surface of the barrier rod 1 so as to emit light, it is preferable because the vehicle driver can be notified of the presence of the barrier rod 1.

  The detecting means 5 detects either the current or voltage of the conductive member 3 or the amount of power consumed by the power consuming body 4 in a state where power is being supplied. When it is disconnected, the current, voltage, or power changes, that is, the current, voltage, or power becomes zero. When this is detected, a signal indicating breaker 1 breakage to the breaker manager 7 is provided.

  In the breaker detecting device for a breaking rod according to the present invention, a conductive member is provided from the base end to the tip along the longitudinal direction of the breaking rod, and any one of current, voltage or power consumption flowing through the conductive member by the detecting means is detected. Therefore, even if breakage occurs in any part of the breaking rod, the conductive member is broken, and any change in current, voltage or power consumption is detected, and breakage of the breaking rod can be detected reliably. It can be suitably used as a breakage detection device for a breaker.

It is explanatory drawing which shows one Embodiment of the breakage detection apparatus of the breaking rod which concerns on this invention.
