Problems solved by technology
[0003] 1. Most of the current anchors have a fixed shape, but the shape of the anchor is larger and the surface area is larger. Therefore, when the anchor is retracted, the water flow resistance of the anchor is greater, and it is more laborious to retrieve the anchor.
[0004] 2. At present, the shape of the anchor fluke is barb-shaped. When it is fixed in the river bed, the anchor fluke sometimes hooks with the rocks in the river bed, and when the anchor is recovered, the anchor fluke is easy to hook with the plants in the water, which increases the safety of the boat. Anchor Recovery Difficulty

Embodiment Construction
[0023] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
[0024] see Figure 1-6 , a retractable and easy-to-recover anchor, including an anchor rod 1, the anchor rod 1 plays the role of connection, and is convenient for fixing the anchor and the active chain 2. The material of the anchor rod 1 is steel and the anchor rod 1 The middle part of the anchor rod is provided with a movable groove suitable for the screw rod 3, the shape of the screw rod 3 is cylindrical and the outer side of the top of the screw rod 3 is pr...

A retractable and easy-to-recover ship anchor relates to the technical field of ship anchors. The sealing ring matched with the screw, the bottom of the screw is fixedly connected with the pull chain, the inner top wall of the anchor is fixedly connected with the spring fixedly connected with the top of the screw, and the middle part of the anchor is connected with the rotation of the outer side of the screw. pole. The retractable and easy-to-recover anchor is used in conjunction with the movable fluke 1 and the movable fluke 2 through the transmission device. When recovering the anchor, the pull chain is first pulled, and the pull chain drives the screw to move downward, and the screw is driven by the transmission device. The movable fluke 1 and the movable fluke 2 are retracted into the fixed fluke to reduce the total surface area of the fluke, thereby reducing the total surface area of the anchor, reducing the resistance between the anchor and the water flow, and achieving easy recovery The effect of reducing the difficulty of recovering the anchor.
Description
technical field [0001] The invention relates to the technical field of ship anchors, in particular to a retractable and easy-to-recover ship anchor. Background technique [0002] The anchor is one of the important tools for berthing a ship. Drop the anchor into the water and insert the anchor into the sand bed to fix the ship on the water surface. It can be moved and is easy to use, but the following problems will occur when the current anchor is used: [0003] 1. Most of the current anchors have a fixed shape, and the anchor has a larger shape and a larger surface area. Therefore, when the anchor is retracted, the water flow resistance the anchor receives is greater, and it is more laborious to retrieve the anchor. [0004] 2. At present, the shape of the anchor fluke is barb-shaped. When it is fixed in the river bed, the anchor fluke sometimes hooks with the rocks in the river bed, and when the anchor is recovered, the anchor fluke is easy to hook with the plants in the w...
