Description

자체 전력 발전 기능을 갖는 지반굴착 로드 비트용 센서하우징{Sensor housing for ground excavation load bit with self-powered power generation function}Sensor housing for ground excavation load bit with self-powered power generation function {Sensor housing for ground excavation load bit with self-powered power generation function}

본 발명은 지하자원의 개발이나 건설 및 채굴을 목적으로 지면을 천공하는 데 사용되고 로드파이프와 드릴비트로 구성되는 굴착장비에 있어서, 센서를 이용하여 각종 굴착상태를 감지하여 작업관리자에게 전송하는 기능을 갖고 이러한 센서 및 전송에 필요한 전력을 자체적으로 생산하여 사용할 수 있도록 한 것이다.The present invention is used to drill the ground for the purpose of development, construction and mining of underground resources, and in the excavation equipment composed of a rod pipe and a drill bit, it has a function of detecting various excavation conditions using a sensor and transmitting them to a work manager. The power required for these sensors and transmission is self-generated and used.

통상의 굴착장비는 맨 선단의 드릴비트 후단에 로드비트가 연결되고 이후에는 연결용 커플링과 로드비트가 계속 연결되는 형태이다.In normal excavation equipment, a load bit is connected to the rear end of a drill bit at the top end, and then a coupling for connection and a load bit are continuously connected.

이러한 굴착장비는 근래 들어 아래 선행기술 문헌과 같이 드릴비트가 지반을 굴착하는 과정에서 지하의 위치와 온도, 진동상태 등의 환경정보를 센서가 수집하여 지상으로 송신하도록 발명되고 있다.In recent years, such drilling equipment has been invented so that a sensor collects environmental information such as the location, temperature, and vibration state of the underground while the drill bit excavates the ground, such as the prior art document below, and transmits it to the ground.

이러한 종래 굴착장비의 작업과정에서 정보 센싱과 송수신 과정에서 필요한 전원을 공급하기 위하여 전지를 이용하거나 진동을 이용하여 발전을 하는 방법을 취하고 있으나, 필요한 센서를 설치할 위치가 적합하지 않아서 정확한 센싱이 어려운 단점이 있으며, 특히 전지의 용량에 한계가 있어서 전원공급이 충분하지 못하였고 진동을 이용한 발전에서도 그 발전량이 충분하지 못하였으므로 깊은 깊이의 굴착과 장시간 굴착 환경에는 제대로 정보를 취득하기 어려운 문제가 있었다.In the working process of such conventional excavation equipment, a method of generating power using a battery or using vibration is taken to supply power required in the process of sensing and transmitting/receiving information, but the location for installing the necessary sensor is not suitable, so accurate sensing is difficult. In particular, the power supply was not sufficient due to the limited capacity of the battery, and the amount of power generation was not sufficient even in power generation using vibration, so it was difficult to properly acquire information in deep excavation and long excavation environments.
