  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

  The column collapse warning device according to the present invention is used by being fixed to a column to be monitored, and issues a warning when it is detected that the column is tilted by a predetermined angle or more.

  FIG. 1 is a diagram for explaining the configuration of a column collapse warning device according to the present invention. The figure (a) shows a front view, and the figure (b) shows a side view.

  As shown in the figure, a column collapse alarm device 100 according to the present invention has a substantially rectangular parallelepiped shape, and includes a light emitting unit 110 on the front side thereof.

  When the column collapse alarm device 100 detects that the column to be monitored is tilted, the light emitting unit 110 is a unit that issues an alarm by emitting light (alarm unit). In the present embodiment, a red light emitting diode ( LED).

  In the column collapse warning device 100, when it is detected that the column to be monitored is tilted, the light emitting unit 110 emits light, so that a maintenance worker or the like can easily recognize that the column is tilted.

  The column collapse warning device 100 includes an inclination sensor 120 inside in order to detect that a column to be monitored is tilted. The inclination sensor 120 has a reference axial direction (reference axis direction) z, and detects that the reference axis direction z is inclined when the reference axis direction z is inclined from the vertical direction to an arbitrary direction by a predetermined angle θ or more. Is configured to do. In the present embodiment, the inclination sensor 120 has a reference axis direction z in the casing of the column collapse alarm device 100 so as to face the longitudinal direction (vertical direction in the figure) of the casing of the column collapse alarm device 100. It is fixed (in parallel with the longitudinal direction).

  FIG. 2 is a diagram for explaining a usage state of the column collapse warning device 100. The figure (a) shows a front view, and the figure (b) shows a side view.

  As shown in the figure, the column collapse warning device 100 is used by being fixed to the side surface of the column 200 to be monitored. The column collapse warning device 100 is fixed to the column 200 so that its longitudinal direction is in the vertical direction (in parallel with the vertical direction). By fixing in this way, the reference axis direction of the internal inclination sensor 120 faces the vertical direction.

  The column collapse warning device 100 is fixed to the column 200 as appropriate by a stainless steel band 210 or the like. Although not shown for simplicity, the casing of the column collapse warning device 100 is formed to have a structure suitable for being fixed to the column 200. Further, as will be described later, the column collapse alarm device 100 has a built-in power source (battery) necessary for operation and does not require an external power source, and therefore can be easily attached to the column 200.

  As described above, when the column 200 to which the column collapse alarm device 100 is fixed tilts from an upright state for some reason, the column collapse alarm device 100 fixed to the column 200 also tilts at the same time. Then, as a result of the tilting of the column 200, if the reference axis direction of the tilt sensor 120 is tilted from the vertical direction by a predetermined angle or more, it is detected that the tilt is detected. By causing 110 to emit light, a warning is given that the column 200 is tilted.

  FIG. 3 is a diagram for explaining the internal configuration of the column collapse warning device 100.

  As shown in the figure, the column collapse warning device 100 includes a battery 130, a tilt sensor 120, a red LED 111, and a resistor 112.

  And the positive electrode (+) of the battery 130 and one electrode terminal of the inclination sensor 120 are connected, and the other electrode terminal of the inclination sensor 120 and the anode (A) of the red LED 111 are connected. In addition, the cathode (K) of the red LED 111 and one terminal of the resistor 112 are connected, and the other terminal of the resistor 112 is connected to the negative electrode (−) of the battery 130. The column collapse warning circuit 300 is configured by connecting the respective parts as described above.

  The battery 130 is a power source (power supply unit) for supplying power for operating (light emission) the red LED 111 that constitutes the light emitting unit 110 (alarm unit). In the present embodiment, two AA batteries that can be stored for a long time (long storage life) are used.

  The tilt sensor 120 is for detecting that the column to be monitored is tilted (tilt detector). In the present embodiment, the tilt sensor 120 includes a cylindrical main body portion and a pair of electrode terminals protruding from the main body portion, and the axial direction (reference axis direction) of the main body portion is oriented in the vertical direction. (When it is parallel to the vertical direction), the pair of electrode terminals is in a non-conductive state, but when it is detected that it has tilted more than a predetermined angle in an arbitrary direction from the vertical direction, The pair of electrode terminals are in a conductive state. The inclination sensor 120 includes therein a first electrode member formed in a mortar shape, a conductive ball placed thereon, and a second electrode member arranged around the first electrode member. In the state (not tilted), the conductive ball is in contact only with the first electrode member and the pair of electrode terminals are non-conductive, but when tilted more than a predetermined angle from the normal state In this case, the conductive ball moves and comes into contact with the second electrode member disposed around the conductive ball so that the pair of electrode terminals are conducted. That is, when the reference axis direction of the tilt sensor 120 is oriented in the vertical direction, the tilt sensor 120 is turned off, the pair of terminals are brought into a non-conductive state, and the reference axis direction is changed from the vertical direction to an arbitrary direction in advance. When it is tilted more than a predetermined angle, it functions as a tilt switch that turns on and turns on a pair of terminals. As such an inclination sensor 120, for example, an inclination sensor manufactured by G-device Co., Ltd. (Nakano-ku, Tokyo) can be used.

  The red LED 111 constitutes the light emitting unit 110 and emits light to warn that the column to be monitored is tilted. The resistor 112 is for limiting the current flowing through the red LED 111.

  In the column collapse alarm circuit 300, while the tilt sensor 120 (its reference axis direction) is oriented in the vertical direction, the electrode terminal of the tilt sensor 120 is in a non-conductive state, that is, the switch is in an off state. No current flows through the circuit, and the red LED 111 does not emit light. On the other hand, as a result of tilting the column collapse warning device 100, if the tilt sensor 120 (its reference axis direction) tilts more than a predetermined angle from the vertical direction in an arbitrary direction, the electrode terminal of the tilt sensor 120 is in a conductive state, that is, Since the switch is turned on, a current flows through the circuit and the red LED 111 emits light.

  In the present embodiment, since the column collapse alarm circuit 300 is configured as described above, a current flows only when the tilt sensor 120 detects a tilt greater than a predetermined angle, and the normal state Then, since the power of the battery 130 is not consumed, the battery 130 can be used for a long time without replacing the battery 130.

  As described above, according to the column collapse warning device 100 described above, when the column to be monitored is tilted by a predetermined angle or more, the light emitting unit 110 emits light and warns that the column to be monitored is tilted. Therefore, it becomes possible for a maintenance worker or the like to easily recognize that the column is inclined.

  In addition, since power is not consumed in a normal state, the battery can be used for a long period of time without replacing the battery.

  As mentioned above, although embodiment of this invention has been described, it cannot be overemphasized that embodiment of this invention is not restricted above. For example, in the above-described embodiment, the light emitting unit performs the alarm by changing the light emission state, but it is also conceivable to perform the alarm by other means (for example, generation of sound).
