Embodiment Construction

[0022] In order to make the object, technical solution and advantages of the present invention clearer, the implementation manner of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0023] In order to better understand the present invention, the structure of the anchor chain wheel machine is briefly described here, figure 1 is a top view of an existing anchor chain wheel, such as figure 1 As shown, the anchor chain wheel 40 is erected on the machine base of the anchor chain wheel machine through the rotating shaft 41, the anchor chain wheel 40 can rotate freely around the rotating shaft 41, and the anchor chain 42 is wound on the anchor chain wheel 40, and the anchor chain wheel 40 is rotated to realize anchoring. The retraction of chain 42.

Abstract

The present invention discloses an anchor chain length indicating device, and belongs to the ship machinery technology field. The device comprises a first gear, a second gears, a decelerator, a pointer and a dial which are coaxially arranged on the rotation shaft of a cable lifter. The second gear is arranged on the input shaft of the decelerator, the second gear is engaged with the first gear, and the pointer is vertically connected with the output shaft of the decelerator. The scales showing the length of the anchor chain are distributed on the dial, and the scales are arranged all around the output shaft of the decelerator so as to obtain the length of the released anchor chain through the scales indicated by the pointer when the cable lifter rotates and avoid the problem that the length of the released anchor chain is not accurate through visual estimation.

Description

technical field [0001] The invention relates to the technical field of marine machinery, in particular to a chain length indicating device. Background technique [0002] The anchor chain is the chain connecting the anchor and the hull, which is used to transmit and buffer the external force on the ship. [0003] When the ship is docked, it is necessary to drop the anchor to make the anchor sink to the bottom of the water. If the length of the anchor chain released is not enough, then the anchor cannot sink into the silt, and if the length of the anchor chain released is too long, then the ship will shake greatly with the wind and waves. Therefore, it is necessary to accurately know the length of the released anchor chain during the anchoring process. When the current ship is anchoring, the length of the released anchor chain is usually judged by the crew's visual inspection, but the visual judgment not only has a large error, but also when the light is insufficient at nigh...
