Embodiment Construction

[0022] Now in conjunction with embodiment, accompanying drawing, the present invention will be further described:

[0023] The embodiment of the device is composed of a bell-mouth guiding buffer module, a clamping module, a lead screw module and a control system module.

[0024] The bell mouth guide buffer module is composed of a bell mouth guide cover 9 and flexible buffer guide rollers 10 . The tail of the bell mouth guide cover 9 is connected with the recovery device main housing 8 by means of ring welding, which has reliable strength and beautiful appearance. In addition, the bell mouth guide cover 9 adopts a double-layer structure, the outer layer is a steel conical shell, and the inner wall is a layer of special flexible plastic with certain elasticity, which can collide with the head of the AUV at the initial stage of AUV recovery to play a role. Guiding role for AUV. The flexible buffer guide roller 10 installed in the head of the main housing 8 is made of the same m...

Abstract

The invention relates to an AUV (Autonomous Underwater Vehicle) recycling and releasing device guided by a horn mouth. The AUV recycling and releasing device consists of a horn mouth guiding buffer module, a clamping module, a lead screw module and a control system module. Recovery, clamping, fixing and release operations of the small AUV are integrated in one device, and meanwhile, a complex mechanical transmission mechanism is avoided, so that the device is simpler in overall structure and more convenient to manufacture and install, and the cost is also reduced. The horn guiding opening is combined with the flexible buffering guiding idler wheel, the function of a traditional single device can be enhanced, after the AUV is guided into the recycling device, the coaxiality of the AUV can be further improved, the damping and buffering effects are achieved, and the requirement for the maneuverability of the AUV is lowered. The middle clamping device can fix the recycled AUV, the guide fixing ring can increase the coaxiality of the AUV in the recycling process, meanwhile, due to the fact that the diameter of the guide fixing ring is large, a sensor and photographic equipment on an AUVshell cannot be damaged, and safety and reliability are achieved.

Description

technical field [0001] The invention belongs to a recovery and release device for a small revolving AUV, and relates to a bell mouth-guided AUV recovery and release device. Specifically, it is based on bell mouth guidance, shock-absorbing roller positioning, and simple mechanical structure clamping and fixing. Background technique [0002] With the continuous development of human society, material civilization will gradually advance to a higher level along with spiritual civilization, and the ocean, which is the source of life, will be further fully developed and utilized. At present, all countries in the world attach great importance to the value of marine resources, and are developing their own technologies related to the development and utilization of marine resources. The competition is very fierce. Similar to the development and utilization of resources on land, some machines for detection and transportation are always needed to complete the pilot work. In the ocean, si...
