Description

Technical Field

[0001] This utility model belongs to the technical field of marine engineering testing equipment, specifically relating to a fixed extension rod device for shipborne salinity testing. Background Technology

[0002] In marine environments, salinity testing is an important means of assessing the chemical properties of seawater. Traditional salinity testing equipment typically uses a fixed-length extension rod, which is extended and retracted via a pulley system.

[0003] Existing technologies suffer from the following problems: 1. Ineffective handling of marine motion: Due to the severe swaying of the marine environment, fixed-length extension rods are prone to rope slippage or equipment damage, affecting test accuracy. 2. Inconvenient deployment and retrieval: Traditional pulley systems are difficult to deploy and retrieval stably in rough seas, increasing operational difficulty and risk. 3. Lack of fixed structure: Existing equipment lacks a fixing device to prevent rope slippage, leading to equipment failure under complex sea conditions. 4. Low installation and dismantling efficiency: The fixed ring structure connected to the hull is usually bolted, resulting in time-consuming installation and dismantling, hindering rapid deployment and retrieval. Therefore, there is an urgent need for a telescopic extension rod device that can adapt to the marine environment and improve testing efficiency and safety. Utility Model Content

[0021] The support frame 1 includes a square tube 1-1, a first lug 1-3, a second lug 1-4, three circular ring components 1-2, two reinforcing ribs 1-5, and a seamless tube 1-6; the three circular ring components 1-2 are spaced apart on the square tube 1-1 to hold the rope in place and prevent it from falling off when it sways at sea.

[0022] The left end of the square tube 1-1 is connected to the seamless tube 1-6, and two reinforcing ribs 1-5 are welded to both sides of the left end of the square tube 1-1 and the seamless tube 1-6; the right end of the square tube 1-1 is connected to the first hanging ear 1-3 and the second hanging ear 1-4; the rotating shaft 3 is set through the round holes on the first hanging ear 1-3 and the second hanging ear 1-4, and the U-shaped pulley 2 is sleeved on the rod part 3-2 of the rotating shaft 3.
