Embodiment Construction

[0024] All features disclosed in this specification, or steps in all methods or processes disclosed, may be combined in any manner, except for mutually exclusive features and / or steps.

[0025] Any feature disclosed in this specification (including any appended claims, abstract and drawings), unless expressly stated otherwise, may be replaced by alternative features which are equivalent or serve a similar purpose. That is, unless expressly stated otherwise, each feature is one example only of a series of equivalent or similar features.

[0026] The specific product we use is a device specially used for hanging rafts, which is installed on the open deck under harsh environmental conditions (-30°C-55°C). Such as figure 1 and figure 2 As shown, from the position where the raft is stored to the position where the raft is retracted, the fixed arm 2 is fixed on the hull 1, and the lifeboat is lifted by the hook 6 or the raft is lowered into the water from the mother ship. During ...

Abstract

The invention relates to an electric heat tracing device for cold protection of deck machinery of a polar ship. The electric heat tracing device comprises a fixed arm and a moving arm, wherein the fixed arm is fixed on the hull, the moving arm is driven by a roller to move back and forth by raking the fixed arm as a track, a heating tube is installed at one end of the shaft in the roller, the other end is mounted with a temperature control probe that is connected to the heating tube through a thermostat and a relay, and the thermostat, the relay, the heating tube and the temperature control probe are respectively connected to a power supply module of the ship. The electric heat tracing device transmits heat to the roller through the shaft due to heat conduction by heating the shaft in theroller component such that the roller temperature is always maintained above 0 DEG C, so as to ensure that the moving arm smoothly protrudes and retracts from the fixed arm. In addition, the electricheat tracing device adopts a thermostat and a relay to automatically start heating or close the heating tube, which realizes intelligent temperature control and solves the problem that the moving armcannot protrude and retract from the fixed arm due to low temperature ice accretion.

Description

technical field [0001] The invention relates to an electric heat tracing device used for mechanical cold protection on the deck of a polar ship, which is suitable for a ship to safely release a lifeboat or a raft in an extremely cold area. Background technique [0002] The polar regions, including the Antarctic and the Arctic, are the coldest regions on Earth. In the past 20 years, with global warming, the melting of Arctic sea ice has accelerated, and the Arctic waterway has been shortened by 40% compared with the traditional Asia-US routes. The shipping benefits are eye-catching. In addition to scientific research purposes in the Antarctic region, Antarctic tourism is growing at a rate of 10%-15% every year. [0003] With the footsteps of human beings extending to the poles, more and more ships are sailing to the coldest regions on the earth. In order to prevent the lifeboat racks from being unable to operate due to ice accumulation in extremely cold regions, steel materia...
