Underwater internal pressure compensation miniature dynamic seal rotation device and underwater monitoring equipment

Abstract

The invention provides an underwater internal pressure compensation miniature dynamic seal rotation device and underwater monitoring equipment. The underwater internal pressure compensation miniature dynamic seal rotation device comprises a sealed cabin, a sealed cabin cover, a sealing body, and output shaft; the sealing body is provided with a step hole; the step hole is located at the end part of the sealing cabin and is fixedly connected with a spring seat; the output shaft is inserted in the step hole through the spring seat; the output shaft is sleeved by two tooth-shaped sealing rings; an isolating ring is disposed between the two tooth-shaped sealing rings; a sealing gasket is disposed between the step surface of the step hole and the tooth-shaped sealing rings; a spring is disposed between the spring seat and the tooth-shaped sealing rings; a detection window is disposed on the sealing cabin cover; an optical lens is fixed sealedly on the detection window. The underwater internal pressure compensation miniature dynamic seal rotation device of the invention can meet underwater dynamic seal requirements of different equipments, and the size is reduced; the weight is decreased; and the sealing performance is improved.

Description

technical field [0001] The invention relates to an optical measuring device, in particular to an underwater internal pressure compensation miniature dynamic seal rotating device and underwater monitoring equipment. Background technique [0002] About three-quarters of the earth's surface is covered by oceans, which contain huge energy sources. At present, all maritime countries are keen on ocean exploration. To know and understand the ocean, various underwater monitoring equipment (such as: submarine observation network camera pan-tilt, submarine optical dissolved oxygen sensor) must be used to collect various chemical components in seawater. For detection equipment that needs to rotate, the problem of dynamic sealing needs to be solved when it rotates underwater. In the prior art, in order to realize dynamic sealing, the sealing device is generally designed for specific testing equipment, and the sealing device has poor versatility and a large overall volume.
