Embodiment Construction

[0021] The specific embodiments of the present invention will be further described below in conjunction with the accompanying drawings.

[0022] figure 1 It is a schematic diagram of a device for hanging and jettisoning heavy objects in deep sea provided by an embodiment of the present invention. The device in this embodiment is entirely installed outboard, as figure 1 As shown, the device includes a hydraulic cylinder 1, a universal joint 2, an intermediate shaft 3, a connector 4, an explosion bolt 5, a safety pin hole 6, and a secondary lever labor-saving mechanism 7.

[0023] Exemplary, figure 1 The heavy object 8 that this device hangs is also shown in.

[0024] The hydraulic cylinder 1 and the intermediate shaft 3 are fixedly connected by a universal joint 2, the intermediate shaft 3 and the explosion bolt 5 are fixedly connected by a connector 4, and the hydraulic cylinder 1 is supplied with oil by an outboard hydraulic source.

Abstract

The invention discloses a device for hanging and discarding a heavy object in deep sea, and relates to the field of deep sea equipment. The device comprises a hydraulic cylinder, a universal coupling,an intermediate shaft, a connector, an explosive bolt, safety pin holes and a two-level lever labor saving mechanism; the hydraulic cylinder and the intermediate shaft are fixedly connected through the universal coupling; the intermediate shaft and the explosive bolt are fixedly connected through the connector; oil is supplied to the hydraulic cylinder by an outboard hydraulic source; the two-level lever labor saving mechanism comprises a first lever and a second lever; the tail end of the first lever is subjected to the contact constraint of the explosive bolt; the tail end of the second lever is used for fixing a lifting lug of the heavy object; and a safety pin is inserted into each safety pin hole when the device is maintained. The problem that a traditional device for hanging and discarding the heavy object is single in driving mode and is only suitable for discarding a heavy object not heavy in weight in shallow water is solved; the effect that the heavy object is discarded by contraction motion of the hydraulic cylinder and by detonating the explosive bolt, and the device is suitable for a deep sea environment is achieved.

Description

technical field [0001] The invention relates to the field of deep sea equipment, in particular to a device for hanging and jettisoning heavy objects in deep sea. Background technique [0002] The device for hanging and discarding heavy objects mainly includes a driving mechanism and an actuator, which must be stable and reliable when hanging heavy objects, and must not fall off by themselves; it is fast, convenient and reliable when throwing heavy objects. [0003] In general, there are many driving modes of the driving mechanism, including manual, hydraulic drive, electromagnetic drive, pyrotechnic drive, etc.; the structural forms of the actuator are also various, including pin shaft type, ring buckle type, embedded, Electromagnetic adsorption, etc. At present, most of the devices for hanging and discarding heavy objects have problems such as single driving mode, mechanical or pipeline penetration, and large driving force. They are usually only suitable for discarding lig...
