Specifically, the camera assembly 500 may be configured as various types of camera devices, such as a wired camera, a wireless camera, a high definition camera, an infrared camera, and the like, and the second drill rod 120 is made of a high-strength transparent polymer material, such as polycarbonate, which is commonly called space glass, and is a high polymer material with high strength, high transparency, and good optical performance, and can meet the strength and transparency requirements of the second drill rod 120.

Further, as shown in fig. 3, the camera assembly 500 includes a camera module 510, an illumination module 520, and a power module 530; the camera module 510, the lighting module 520 and the power module 530 are all mounted on the inner wall of the top of the second drill rod 120, and the camera module 510 and the lighting module 520 are all electrically connected with the power module 530.

Specifically, the camera module 510 is set as a high-definition camera, the lighting module 520 is set as a plurality of LED lighting lamps, the power module 530 is set as a rechargeable battery, and both the camera module 510 and the lighting module 520 are connected with the battery through a connection harness, so that the battery is the normal working electric energy of the camera module 510 and the lighting module 520.

Further, the camera module 500 further includes a communication module 540; the communication module 540 includes a signal transmitting portion and a signal receiving portion, both of which are in communication connection with the camera module 510, and both of which are electrically connected with the power module 530; the signal transmitting part is used for transmitting image information shot by the camera module 510 to a remote device, and the signal receiving part is used for receiving an instruction of the remote device and transmitting the instruction to the camera module 510.

Specifically, the signal receiving part is set as a wireless signal receiver, the signal transmitting part is set as a wireless signal transmitter, the signal receiving part and the signal transmitting part are both connected with the power module 530 through power supply wires, and the signal receiving part and the signal transmitting part are both connected with the camera module 510 through signal wires; the remote device is preferably configured as a notebook computer, the signal transmitting portion transmits the image information captured by the camera module 510 to the notebook computer, and accordingly, the control software in the notebook computer can adjust the relevant parameters of the camera module 510, such as the pixels, the focal length, the resolution, and the like, through the signal receiving portion.
