Description

Borehole wireless imaging equipment {Wireless apparatus for photographing the drilling hole}

The present invention relates to a borehole wireless photographing device, and more specifically, to solve various wastes of the existing borehole photographing equipment connected by wire with an underwater camera, to improve the installation and use easily, and to solve the electric shock risk in rainy weather. A new borehole wireless imaging device.

In general, the borehole photographing equipment is used for exploring groundwater or geological and ground surveys, and as shown in FIG. 1, an underwater camera that is hung on a wire after drilling a drilling rod 2 of a steel pipe to an underground deep part of a desired location. (32) is inserted into the borehole 2a so that the screen can be observed through the monitor 38 installed on the ground.

However, in the related art, such a borehole photographing equipment has been connected to the wire between the underwater camera 32 and the ground monitor 38 by wire, and the camera wiring is waterproof to enter a length of several tens to several hundred meters underground. 34 allows the camera to be inserted deeply into the borehole while unwinding the reel (wound) while being wound on the reel 42 on the ground unit, where the underwater camera 32 enters the borehole 2a and is underground. Depth to go down can be read using the encoder 36 installed in the unit 41 provided with the reel 42, the encoder 36 is a pulse generated by the rotation of the roller in accordance with the movement of the camera wire (34) It was a method of acquiring depth data by a signal, and an end portion of the camera wire 34 was wound at the deepest portion of the reel 42 and connected to one side of the reel unit 41 by a 4-wire 4-pin sleeve 44. Monitor (38) Associated with the ratio was configured to be able to reproduce on the monitor 38, the image pickup information of the underwater camera 32.

The conventional borehole imaging equipment is connected to the electrical connection of the four sleeves 44 of the reel unit for power supply and signal connection of the underwater camera, the bar is not only attenuated signal in rainy weather ( There is a problem that 220V AC power applied to the reel unit 41 to supply the power current of 32) may cause an electric shock to a person by biting.

In addition, in order to install the monitor 38 in a long distance, there is a difficulty in lengthening the wiring 43 connecting to the sleeve 44. In order to lengthen the connection of the wiring 43, the signal transmission is attenuated by that much. There is a need for a separate equipment such as the need for an AC 220V power line to supply a booster (or a sleeve of the reel), which also had the problem that the risk of electric shock in the rain.

In addition, since the support 52 for supporting the pulley 54 is installed on a tripod to enter the camera in the borehole driveway, the volume and weight are large enough to be inconvenient to carry. There was also a lack of safety, which may leave the position or collapse due to an impact transmitted during feeding of the camera wiring 34 later.

The present invention devised to solve the above-mentioned problems is aimed at providing a borehole wireless photographing device that can shorten the electrical wiring, eliminate the risk of electric shock in the rain, and is easy to install and use.

Another object of the present invention is to make it easy to install the pulley support to turn the camera wiring to the borehole with a simple structure and to improve the stability.

It can be implemented as various embodiments of the present invention.

Borehole radiographic equipment of the present invention as the first embodiment,

It is installed by hanging on the wiring wire 134 wound on the reel 142 installed on the ground, and is supplied with power by the wiring wire 134 and an underwater camera 132 for capturing the inside of the borehole 2a, and the reel 142. A signal processing and wireless transmitting unit 162 connected to an end of the wire wire 134 wound by the wire) to modulate the imaging information transmitted from the underwater camera 132 into radio waves to wirelessly transmit the modulated signal; Wireless reception and signal processing unit 164 for demodulating the wireless received signal by wirelessly receiving the wirelessly transmitted signal at a remote location to obtain the imaging information of the underwater camera, and output signal of the wireless reception and signal processing unit 164. The monitor 138 is configured to reproduce the borehole image.

The power of the underwater camera 132 uses a DC 12V secondary battery (charger) 172 installed in the reel unit 141 and is supplied through the wiring wire 134.

The wiring wire 134 is preferably an outer coating or embedded in a flexible pipe so that the internal electrical wiring is insulated from the outside.
