Description

Ocean observation instrument and its anchor release mechanism

The present invention relates to an anchor release mechanism, and more particularly to an anchor release mechanism for use in an ocean observation instrument.

The deployment and recycling of ocean observation instruments is related to the acquisition of long-term data samples and the analysis of subsequent data samples. The sampling points of ocean observations are generally in the deep sea. The depth is as shallow as two or three hundred meters and the depth is two or three kilometers. Therefore, the design of ocean observation instruments plays a very important role.

The anchor release mechanism of the conventional ocean observation instrument mainly burns the cable by means of electric burning to release the anchor, or separates the anchor by a brake action. Conventional anchor release mechanisms are generally integrally formed. In consideration of the deep water pressure resistance and the density of seawater, the appearance is cumbersome, expensive, and cannot ensure that the instrument is completely separated from the anchor when released.

The present invention provides an anchor release mechanism for solving the problems of the prior art for releasing an anchor, including a base, a hook and a brake. The hook pivots the base and pivots between the first hook orientation and the second hook orientation. When the hook is in the first hook orientation, the hook abuts the base and limits the An anchor that releases the anchor when the hook is in the second hook orientation. The brake limits rotation of the hook when the hook is in the first hook orientation, and when the anchor is to be released, the brake releases the hook to allow the hook to rotate from the first hook orientation To the second hook orientation.

The anchor release mechanism of the invention uses the principle of lever to release the anchor, and its pivotal fulcrum is close to the point of application (contacting the position of the cable), so that the overall force is averaged, and the safety can be improved to achieve the purpose of release. The restriction hook has a slope to ensure the detachment of the anchor. The anchor release mechanism of the present invention has lower cost, higher reliability, and can be reused.

Referring to Fig. 1, there is shown a marine observation apparatus 1 according to an embodiment of the present invention, comprising a base 11, a float 20, an anchor 30, a hook 12 and a brake 13. The float 20 is provided on the base 11. The hook 12 is disposed on the base 11 for restraining or releasing the anchor 30. The brake 13 is provided on the base 11 for restricting or releasing the hook 12.

Referring to Figures 2A and 2B, there is shown a detailed structure of the anchor release mechanism 10 (partial base 11, hook 12 and brake 13) of the marine observation instrument 1 of the present invention. The hook 12 pivots the base 11 and pivots between a first hook orientation (as shown in FIG. 2A) and a second hook orientation (shown in FIG. 2B). When the hook 12 is in the first hook orientation, the hook 12 abuts the base 11 and limits the anchor 30. The hook 12 releases the anchor 30 when the hook 12 is in the second hook orientation.

The hook 12 has a positioning hook portion 121 and a restriction hook portion 122. The positioning hook portion 121 and the restriction hook portion 122 are respectively located at two ends of the hook 12 . The positioning hook 121 contacts the brake 13 in a detachable manner, and the restriction hook 122 has a slope and contacts the anchor 30 in a detachable manner.

Referring to FIG. 2A, when the hook is in the first hook orientation, a restriction space 14 is formed between the hook 12 and the base 11. The anchor 30 has a loop 31 through which the loop 31 passes so that the anchor 30 is hung from the anchor release mechanism 10. Referring to FIG. 2B, when the hook is in the second hook orientation, the restriction space 14 is opened, and the loop 31 slides on the slope to disengage the anchor release mechanism 10.

The brake 13 is a motor. When the hook 12 is in the first hook orientation, the brake 13 limits the rotation of the hook 12. When the anchor 30 is to be released, the brake 13 releases the hook 12 to allow the hook 12 to The first hook is rotated in orientation to the second hook orientation.

The brake 13 includes a limiting protrusion 131 that moves between a first bump position (as shown in FIG. 2A) and a second bump position (shown in FIG. 2B). When the limiting protrusion 131 is located at the first protrusion position, the limiting protrusion 131 abuts the positioning hook 121 of the hook 12 to limit the rotation of the hook 12 . When the brake 13 moves the rotation of the restriction projection 131 away from the first projection position, the restriction projection 131 releases the hook 12.

The anchor release mechanism of the invention uses the principle of lever to release the anchor, and its pivotal fulcrum is close to the point of application (contacting the position of the cable), so that the overall force is averaged, and the safety can be improved to achieve the purpose of release. The restriction hook has a slope to ensure the detachment of the anchor. The anchor release mechanism of the present invention has lower cost, higher reliability, and can be reused.

Although the present invention has been described above in terms of the preferred embodiments thereof, it is not intended to limit the invention, and those skilled in the art can make some modifications and refinements without departing from the spirit and scope of the invention. Therefore, the scope of the invention is defined by the scope of the appended claims.
