Description

Technical Field

[0001] The utility model relates to the technical field of radiation-resistant cameras, in particular to a radiation-resistant camera. Background Art

[0002] A camera is a radiation-resistant camera that uses the principle of optical imaging to form an image and uses film to record the image. When an existing camera needs to record images in a specific environment, the camera is usually installed on an electric pan head, and the shooting angle of the camera is adjusted by rotating the electric pan head. When the camera is used in an underwater environment, the camera and the electric pan head are usually installed in a closed waterproof casing to prevent the camera and the electric pan head from contacting water. However, the electric pan head needs to pass through the closed waterproof casing and the waterproof casing on the outside of the camera through a shaft. This type of connection through a shaft may cause internal water seepage due to poor sealing when working underwater with radiation for a long time, so that the radiation in the water will interfere with the image recording, directly affecting the accuracy and clarity of image acquisition.

When the horizontal shooting angle of the camera 204 needs to be adjusted, the first driving assembly works. When the first stepper motor 5 works, the first transmission shaft 501 and the rotating shaft can drive the upper first gear 503 to rotate.

[0037] When the radial shooting angle of the camera 204 needs to be adjusted, the second driving assembly works. When the second stepping motor 6 works, the second gear 603 on the right side can be driven to rotate through the second transmission shaft 601 and the rotating shaft. The second gear 603 on the right side can be meshed with the second gear 603 on the left side for transmission, so that the second gear 603 on the left side drives the second worm 602 to rotate through the rotating shaft. The second worm 602 can mesh with the turbine 411 on the left side, so that the mounting shell 408 on the left side rotates. When the mounting shell 408 on the left side rotates, the second permanent magnet 407 can be driven to rotate through the second limit screw 410. The sealing shell 403 on the left side is fixed to the first waterproof shell 1, so that the sealing shell 403 on the left side is in a fixed state, so that the second permanent magnet 407 drives the first permanent magnet 401 to rotate under the action of magnetic force, and the first permanent magnet 401 drives the first fixed cylinder 205 to rotate through the fixing screw 402, and the first fixed cylinder 205 drives the second waterproof shell 2 and the camera 204 inside it to rotate radially. At the same time, when the first fixed cylinder 205 rotates, the first limiting screw 108 on the same side thereof can rotate relative to the annular groove 302 on the first fixed cylinder 205, and the annular groove 302 can guide and limit it.
