An external detection device for a ship's anchor chain

Abstract

The invention provides an anchor chain releasing detection device for a ship. The anchor chain releasing detection device comprises a rotating disc. A transverse clamping shaft is clamped in the middle of the rotating disc, and the rotating disc is rotationally embedded in a protective cover through the transverse clamping shaft; six groups of driving levers are connected to the peripheral side ofthe rotating disc; the outer ends of the driving levers can be attached to and extrude the outer wall of the elastic plate on a second detection mechanism. The second detection mechanism comprises the elastic plate, a movable contact and a fixed contact, a transverse bevel gear is further clamped to the other end side of the transverse clamping shaft, and the transverse bevel gear is in transmission connection with a first detection mechanism. In the anchor chain lowering or retracting process, the driving levers drive the rotating disc to rotate to drive a large gear to rotate to enable thelarge gear to move on the threaded rod, a displacement detection sensor is utilized to detect the moving distance of the large gear and extrude the elastic plate to enable the movable contact to makecontact with the fixed contact, and thus the releasing state of the anchor chain is detected in the two modes, the releasing or retracting pitch number of the anchor chain is calculated and higher accuracy is achieved.

Description

technical field [0001] The invention belongs to the technical field of ship shipping, and more specifically relates to a ship anchor chain release detection device. Background technique [0002] Anchor chain refers to a special chain that connects the anchor and the hull and transmits the anchor's grasping force. It is often composed of anchor end links, middle links and end links. There are two types of anchor chains, the strength of the former is greater than that of the latter; according to the manufacturing method, anchor chains can be divided into cast steel anchor chains and electric welding anchor chains, etc. The length of the anchor chain is in knots, and the standard length of each anchor chain is 27.5 m, and the joints are connected by connecting links or connecting shackles. Usually, the chain length of the main anchor on each side of the 10,000-ton ship is about 12 knots. [0003] For example, in the patent with the application number: CN201920225358.2, a ship ...

AI Technical Summary

Problems solved by technology

[0005] In order to solve the above-mentioned technical problems, the present invention provides a ship anchor chain release detection device to solve the problem that the permanent magnetic ball is easily adsorbed to the hull, or the hull responding to the position of the iron block produces weak magnetism, which affects the action of the pressure sensor. It leads to errors in the calculation of the length of the anchor chain, and only a single detection method is used, which has no contrast and affects the accuracy of detection.
