Description

  The present invention relates to a landslide disaster warning device that immediately informs the surroundings of the occurrence of landslides and changes in the surface of the earth and prevents accidents. A collapse includes a natural object such as earth and sand, snow, and a structure such as an artificially created wall, and the state of the object has changed from the original state.

As known in the literature 1 as a conventional collapse disaster warning device, a sensor wire for detecting the movement of earth and sand is routed to an appropriate length, and the alarm device is operated by pulling the sensor wire due to the movement of the earth and sand. It was.
Such a device can detect the movement of earth and sand reliably, but it is difficult to install, and there is a danger of malfunction due to birds and beasts because the sensor wire is stretched close to the ground surface, so signal processing to prevent malfunction It was necessary. .

In addition, the one shown in Document 2 detects a change in the crust using an acceleration sensor, and attaches a sensor unit to a pile-like support member inserted into the ground and transmits the change by a radio signal. It is.
Since such a device is assembled as a single device, it is common in that it can be installed and used at an appropriate point, but it is complicated and expensive because it is used as a system using radio signals. Therefore, it is not a preferable device for installing a large number of devices.

  The problem to be solved is to complete the work in a short time in a place where the installation work itself is dangerous, and to prevent malfunction due to birds and beasts.

  As a means for solving the problems of the prior art described above, the present invention includes a sensor case that tilts or falls when a collapse disaster occurs, and a sensor case that operates by detecting the tilt or falls of the case. It is characterized by having a sensor disposed and a signal generator that operates in accordance with a signal of the sensor disposed in the sensor case.

According to the present invention, a sensor case that tilts or falls when a collapse disaster occurs, a sensor that is disposed in a sensor case that operates by detecting the tilt or fall of the case, and a sensor case that is disposed in the sensor case. Because it has a signal generator that operates according to the signal of the sensor, it is possible to immediately notify a large number of residents of a disaster in a remote area at once, and all of them can take immediate action, promptly responding to evacuation, etc. Can be taken. In addition, since the occurrence of a collapse disaster is detected by a unit attached to the tip of a support pile raised from the ground, the amount of displacement of the unit can be increased against a slight change in the ground surface, and the collapse can be caught reliably. . Furthermore, because it consists of a support pile and a sensor unit, it can be installed freely in a hazardous area and has the advantage that it can be handled very easily without the need for power supply work or sensor cords.
In particular, since the phenomenon of collapse is notified by so-called fireworks that are launched into the sky together with explosives by the explosion of explosives, it has a remarkable effect that can be informed to the surrounding residents at once.

  Hereinafter, an example of an embodiment of the present invention will be described with reference to FIGS. 1 points to the surface of the earth and marks the area where there is a risk of collapsing with halftone dots. Reference numeral 2 denotes a sensor case, which is formed into a hollow interior by a weatherable material such as resin or metal, and a guide 4 for attaching a support pile 3 inserted into the center is provided on a surface corresponding to the bottom surface of the sensor case. Yes. In addition, the guide 4 has a protruding shape in the drawing, but may be formed in a concave groove shape so that the support pile 3 can be securely attached.

  Reference numeral 5 denotes a screw for fixing the support pile. 6 is a sensor mounted in the sensor case 2, and an operation piece 9 of the switch 8 is projected from a hole at the bottom of the plate 7 at the bottom of the plate 7 formed of resin whose center is lowered. Further, the switch 8 is electrically opened by depressing the operation piece 9, and is electrically connected when free. 10 is an operation piece 9 of the switch 8 that is normally pressed down and is a large-sized sphere that is electrically open to release the operation piece 9 when the sphere is displaced by a change such as a tilt due to a collapse disaster. A sensor 6 is configured by the pan 7, the switch 8, the operation piece 9, and the ball 10. 11 is a solar panel provided on the upper outer peripheral surface of the sensor case 2, 12 is a battery serving as a power source 13 charged by the solar panel, 14 is a controller 15 for controlling the charging of the solar panel 11, and the operation of the sensor 6 is a radio signal. Although it is an electric circuit board provided with the transmitter 16 which transmits as a signal, a signal can be sent to a disaster prevention system or the like installed in the base station (not shown), and an emergency warning or the like can be taken.

  Reference numeral 17 denotes a transmission antenna which is attached to the sensor case 2. Reference numeral 18 denotes a launch tube formed on the top of the sensor case, and houses a signal generator 19 filled with explosives. Further, the signal generator 19 ignites the explosive by a firing device 20 using a heating wire or a piezoelectric element, thereby generating an explosion sound and launching the signal bullet 20 into the sky. Reference numeral 22 denotes a lid of the launch tube 18, which stores the signal generator 19 in an airtight manner and breaks with the firing of the generator 19 so that it does not come off the launch tube and does not hinder the launch of the signal bullet.

  By configuring as described above, the sensor case 2 is tilted due to the collapse of the earth and sand due to the tilting or falling of the support pile 3, so that the ball 10 rolls from the bottom bottom of the pan 7 and moves the operation piece 9 of the switch 7. Since the ignition device 20 is energized in a free state, the signal generator 19 operates and launches the signal bullet 20 into the sky together with the explosive sound. Moreover, it is also possible to send an emergency warning or the like by sending a signal to a disaster prevention system installed in the base station using a transmitter as necessary.

It is explanatory drawing which showed the structure of this invention. It is explanatory drawing which shows the state of each part at the time of collapse detection of this invention. It is an electric circuit diagram by the structure of this invention. It is explanatory drawing of the installation state of this invention, and the state at the time of collapse.
