Description

Technical Field

[0001] The present invention relates to the technical field of measuring equipment, and in particular to a detection outer tube structure for deep-sea measurement. Background Art

[0002] Deep-sea exploration refers to the scientific research and exploration of the deep ocean. These explorations typically involve the use of various equipment and technologies, such as sonar, unmanned submersibles, and deep-sea equipment, to obtain data and information on seafloor topography, marine life, and the hydrological environment. Deep-sea exploration is crucial for understanding Earth's oceans, biodiversity, and geological structure.

[0003] A Chinese patent with authorization announcement number CN114910054B discloses an outer tube structure for deep-sea surveying. The outer surface of the functional tube is provided with a skin, a support tube is provided in the middle of the functional tube, an action box is provided on both sides of the support tube, a force storage block is provided inside the action box, extension rods are provided on both sides of the force storage block, and blades are provided at the ends of the extension rods. A spring-loaded tube is provided in the middle of the action box away from the support tube, and a pressure block is provided inside the spring-loaded tube. When seaweed is wrapped around the outside of the tube, the resistance of the corresponding side in the seabed current is increased, thereby triggering the action box. The force storage block will drive the blade to pop out at high speed, cutting the wrapped seaweed and separating it from the outer tube to prevent the seaweed from entangled with each other, continuously increasing the flow resistance outside the tube, and thus hindering the detection operation.

[0036] The protective tube 2 is sleeved on the outer tube body 1. There are high salinity and corrosive substances in the deep-sea environment. The protective tube 2 can effectively protect the outer tube body 1 from corrosion and extend its service life; the positioning component has a fixed state and a tightened state. In the fixed state, it is used to position the protective tube 2; in the tightened state, the fixing plate 10 is separated from the protective tube 2, which facilitates the disassembly and assembly of the protective tube.

[0037] like Figure 1-Figure 3 As shown, the positioning assembly also includes a fixing frame 3, a connecting column 11 and a connecting plate 12; at least one fixing frame 3 is arranged in the outer tube body 1, and the fixing frame 3 is a cross-shaped frame; the driving transmission mechanism includes a driving part and a transmission part; the connecting column 11 is rotatably arranged on the fixing frame 3, and a driving part for driving the connecting column 11 to rotate is provided on one side of the fixing frame 3; the connecting plate 12 is provided on the connecting column 11 and is located on the side of the fixing frame 3 away from the driving part, and a transmission part for driving the fixing plate 10 to slide is provided between the connecting plate 12 and the fixing plate 10, and the fixing plate 10 can fix the protective tube 2, which can ensure that the protective tube 2 is firmly fixed on the outer tube body 1 to prevent movement or falling off during seabed operation, thereby improving the stability of the entire system.
