The invention belongs to the field of underwater robots, and specifically relates to an underwater robot recovery system and a recovery method thereof. The system includes a mother ship, an underwater robot, an automatic line throwing device and a lifting seat arranged on the underwater robot, a butting lifting device and a draw gear. After the underwater robot completes the mission, a haulage rope is thrown out from the ship bow. The staff on the mother ship picks up the haulage rope through a rope picking device, and then the rope is traversed through the draw gear. The underwater robot is driven by the mother ship for navigation to overcome the effects of waves in the sea. A guidance rope is thrown by a remote control command. The butting lifting device is driven by a hoist installed on the mother ship, and falls down along the guidance rope to abut with the underwater robot and clamp. The whole recycling process is realized. The underwater robot recovery system of the present invention has the characteristics of compact structure, convenient operation, safety and reliability, small influence by the sea state, no transform to the hoist, and small requirement to the mother ship, and can achieve the laying and recovering by the same system for the underwater robot under four grade sea conditions.

The disclosure relates to a method for guiding a pilot of an approaching aircraft to a stop position at a stand, said method being characterized by: monitoring a position of the approaching aircraft within a volume at the stand, comparing said monitored position with a first area, said first area enclosing the stop position, comparing said monitored position with a subsection of the first area enclosing the stop position, if said monitored position is inside said subsection: transmitting information to a display to show an indication to the pilot to proceed approaching the stand, and if said monitored position is inside the first area but not inside said subsection: transmitting information to the display to show an indication to the pilot to stop the aircraft. The disclosure further relates to an aircraft docking system.

The invention discloses a quick connector and an application method and belongs to the technical field of drilling equipment and tools in the petroleum industry. The quick connector comprises a male connector body, a female connector body, a steel ball / clamping block locking device and a looseness preventing device. One end of the male connector body is connected with a bypass valve through a thread, the other end of the male connector body is a plug, one end of the female connector body is fixedly connected with a high-pressure pipeline through a union, the other end of the female connector body is a jack, and the plug of the male connector body can be plugged into the jack of the female connector body. Sealing is achieved by a sealing ring in the jack, the steel ball / clamping block locking device is used for locking, quick butt joint between the bypass valve and the high-pressure pipeline is achieved, and after plugging and locking, a drill rod pup joint body can be tightened by the looseness preventing device to prevent the connector from loosening accidentally.

The invention discloses an embedded type cabin section axial horizontal butt joint device which comprises a bottom support frame, a horizontal guide rail, an angle brace, a first cabin section mounting frame, a first embedded cabin section support module, a second embedded cabin section support module, a ball screw mechanism and a second cabin section support module, wherein the first cabin section mounting frame is used for installing a first cabin section; the first embedded cabin section support module and the second embedded cabin section support module are used for supporting an embedded type cabin section in a way of cooperation and adjusting the height of the embedded type cabin section so as to guarantee an interface of the embedded type cabin section to be aligned with an interface of the first cabin section; the ball screw mechanism is used for driving the two support modules to support the embedded type cabin section together to enable the embedded type cabin section to move closely to the first cabin section so as to complete axial horizontal butt joint, and is used for driving a second cabin section arranged on the second cabin section support module to move closely to the first cabin section so as to complete the axial horizontal butt joint of the three cabin sections. The invention also provides an embedded type cabin section axial horizontal butt joint method. After the device and the method are adopted, radial small-gap embedded type cabin section butt joint can be realized; the device and the method are convenient to operate and high in work reliability.

The invention discloses a multi-degree-of-freedom missile bay section butt joint device. The multi-degree-of-freedom missile bay section butt joint device comprises a vehicle body and a butt joint system. The vehicle body comprises a vehicle frame and wheels. The wheels are installed under the vehicle frame. The butt joint system is installed on the vehicle frame and comprises lifting mechanisms, posture adjustment mechanisms, feeding mechanisms and supporting mechanisms. The lifting mechanisms used for lifting missile bay sections are fixed to the vehicle frame. The lifting mechanisms are sleeved with one ends of the posture adjustment mechanisms, and the other ends of the posture adjustment mechanisms are connected with the feeding mechanisms. The supporting mechanisms are installed on the feeding mechanisms. According to the multi-degree-of-freedom missile bay section butt joint device, the advantages of a hoisting butt joint mechanism and the advantages of a lead screw and nut butt joint mechanism are combined; a flexible butt joint form is adopted, and adjustment of the butt joint postures of the missile bay sections is achieved through ball hinge assemblies and limiting assemblies; operation is flexible and easy, and butt joint can be achieved rapidly, safely and reliably; in addition, the structure is simple, and the manufacturing cost is low; the butt joint system is installed on the vehicle frame, thereby being suitable for being transferred from one site to another site.
