Description

Disaster relief equipment

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a disaster relief apparatus adapted to perform various construction work and hazardous material removal work in order to relieve a disaster area and more particularly to a disaster relief apparatus which is applied to an excavator and usually performs relief work such as excavation, During the relief work in the buried area or minefield area, it is possible to detect and remove hazardous materials such as land mines buried in the ground, so that it is possible to reliably recover the disaster area due to natural disasters in civil war or military areas. And a disaster relief device that can be carried out.

In general, in natural disaster areas such as earthquakes and floods, and in human disaster areas such as civil wars (war), reconstruction work such as digging and filling the ground is essentially performed.

In order to perform such a restoration work, an excavator such as a forklake is mainly used.

On the other hand, in areas where landmines are buried or where landmines and natural disasters are mixed, it is necessary to detect and remove buried or lost landmines, and then perform restoration work.

That is, the process of detecting and removing land mines and the restoration work in the area where mines are removed are sequentially performed.

In the above, the process of removing land mines is mainly carried out by a land mine removal expert by inputting human resources. Various devices and methods for performing safe operations in land mine removal work have been proposed. There is a problem that the safety accident such as the explosion of the vehicle is caused, resulting in human and material damage.

In recent years, there have been proposals for apparatuses for detecting landmines in buried landmines and mineswelling in recent years, and in Korean Patent Registration No. 10-1544278 (name: mine detection robot), as known in the art, part; A detection unit installed in the autonomous drive unit and detecting a land mine buried underground; An image unit installed in the autonomous drive unit and generating image information by recording a peripheral image of the autonomous drive unit; A communication unit for generating position information of the autonomous driving unit and transmitting the generated information to the outside, and receiving the video information from the video unit and transmitting the information to the outside; A spraying unit installed in the autonomous drive unit and spraying a fluid to a surrounding ground surface of a land mine detected by the detection unit; A level signal generation unit for receiving a signal from the detection unit and comparing the received signal with a threshold value, thereby generating a level signal by dividing the possibility of landmine burdens into various levels to determine each level signal; And a control unit which receives a level signal from the level signal generation unit and controls the image unit, the communication unit, and the injection unit according to each level signal, wherein the level signal generation unit generates a level signal, And generates a first level signal when the first level signal is smaller than the first threshold value and generates a second level signal when the first level signal is greater than the first threshold value and smaller than the second threshold value, The control unit generates the third level signal when the first level signal is received from the level signal generation unit, and when the first level signal is received from the level signal generation unit, the communication unit transmits the position information of the autonomous travel unit to the outside When the second level signal is received from the level signal generation unit, the image unit records the peripheral image of the autonomous driving unit to generate image information, The communication unit controls the communication unit to transmit the image information generated from the image unit and the position information of the autonomous drive unit to the outside, and when the third level signal is received from the level signal generation unit, Controlling the injection unit to inject fluid onto a peripheral surface of a land mine detected by the detection unit, and controlling the image unit to record image information by recording the peripheral image of the autonomous vehicle in the image unit, And controlling the communication unit to transmit generated image information and position information of the autonomous drive unit to the outside.

On the other hand, separate equipment such as an excavator for performing a recovery operation in a mine-removed area has been put into operation to perform a separate recovery operation, which has been costly and time-consuming.

Accordingly, there have been proposed devices and equipments for improving work efficiency by simultaneously carrying out removal and restoration of land mines.
