Description

Technical Field

[0001] This utility model relates to the field of grippers, specifically to a gripper for underwater operations. Background Technology

[0002] This utility model relates to the field of underwater operation equipment. During underwater operations, it is often necessary to stabilize and fix the operating equipment or devices, as well as to carry out the operation of cables and other related items to ensure that the underwater operation can be carried out smoothly and efficiently. Therefore, the development of relevant auxiliary tools suitable for the underwater operation environment has important practical significance.

[0003] Existing underwater anchoring devices have limited functionality, often only suitable for securing specific types of substrates or fixed objects. Furthermore, when underwater operations involve cable retrieval and deployment, existing devices lack effective start-stop control structures, making it prone to cable loss of control during the process. This inability to accurately stop retrieval or deployment as needed causes numerous inconveniences and impacts operational efficiency and safety. Therefore, those skilled in the art have developed an underwater anchoring device to address the problems described in the background section. Utility Model Content

[0004] The purpose of this utility model is to solve the above-mentioned defects and provide an underwater gripper. Through its fixed gripping structure and cable reeling component, it solves the technical problems of existing underwater operation fixing devices having relatively simple functions and the cable easily going out of control during the reeling and deployment process, making it impossible to accurately stop reeling or deploying the cable at any time according to the operation requirements.

[0005] The objective of this utility model is achieved through the following means:

[0006] An underwater gripper includes a mounting base, a fixed cone, a suction cup, and a fixed seat. The fixed cone, suction cup, and fixed seat are arranged around the periphery of the mounting base. A support is installed on the outer wall of the mounting base. A vertical groove is formed inside the fixed seat, and a rack is installed in the groove. A bolt is threaded to the front side of the rack. Gears are arranged on the left and right sides of the rack, and grippers are installed on the gears. A take-up groove is formed in the middle of the mounting base, and a take-up roller is arranged in the take-up groove. A ratchet is installed on the side of the take-up roller facing the take-up groove. The ratchet is rotatably engaged with the mounting base. A retaining strip is inserted into the outer wall of the mounting base. A through groove is formed in the retaining strip, and a limit rod is installed in the through groove. A spring is sleeved around the periphery of the limit rod.

[0007] Furthermore, the fixed cone is fixedly installed with the support, and a spiral barb is provided on the outer wall of the fixed cone.

[0008] Furthermore, the gear is rotatably engaged with both ends of the fixed base, the two sides of the rack mesh with the gear, the rack is slidably inserted into the slide groove, and the bolt passes through the positioning hole and is threadedly connected to the rack, thereby positioning the rack and fixing the gripper.

[0009] Furthermore, the spring is a tension spring, with one end connected to the outer wall of the mounting base and the other end connected to the inner wall of the through groove. Under the action of the spring, the locking strip always remains engaged with the ratchet, thereby enabling the take-up roller to start and stop.

[0010] Furthermore, a handle is installed on the outer wall of the take-up roller away from the take-up groove, which is used to rotate the take-up roller to wind up the safety rope.

[0011] The beneficial effects of this utility model are as follows: By connecting three supports with different accessories around the mounting base, multiple fixing modes are achieved. The surface of the fixing cone is provided with threaded barbs, which can be used to fix soft bottoms; the suction cup can be adsorbed onto smooth surfaces through negative pressure; when encountering irregular objects such as coral, the cooperation of the sliding groove, rack, bolt, gear and claw on the mounting base is used. After the bolt is unscrewed, the rack squeezes and the claw retracts to clamp the fixed object. Then the bolt is passed through the positioning hole and connected to the rack to achieve positioning, thereby fixing the claw. The variety of fixing modes makes this gripper suitable for different environments. At the same time, a take-up groove is opened on one side of the middle of the mounting base and a take-up roller is set. Through the cooperation of ratchet, locking strip, limit rod and tension return spring, the locking strip is always engaged with the ratchet under the action of the spring, realizing the start and stop effect of the take-up roller, which facilitates the operation of cables and other objects during underwater operations.
