Emergency load rejection and position indicating device and method of unmanned underwater vehicle

The invention provides an emergency load rejection and position indicating device of an unmanned underwater vehicle. The emergency load rejection and position indicating device of the unmanned underwater vehicle comprises an emergency load rejection unit with a counterweight. A position indicating unit is arranged below the counterweight. The counterweight is located between the underwater vehicle and the position indicating unit. The position indicating unit comprises a floating body. The floating body is internally provided with a communication positioning antenna, a control unit, a battery and a water depth pressure sensor. The underwater vehicle, the counterweight and the floating body are connected through explosive bolts. The explosive bolts movably penetrate through through holes in the counterweight and then are fixedly connected with the floating body. The control unit comprises a single chip microcomputer, a communication positioning module and a control circuit. A communication cable is arranged between the single chip microcomputer and the communication positioning module. A transmission wire is arranged between the water depth pressure sensor and the single chip microcomputer. The single chip microcomputer controls ignition of the explosive bolts through the control circuit. The communication positioning antenna is connected with the communication positioning module through a feedback line. Power is supplied to the position indicating unit through the battery. The invention further provides a corresponding emergency load rejection and position indicating method. According to the emergency load rejection and position indicating device and method of the unmanned underwater vehicle, the dual functions of emergency load rejection and position indicating can be achieved, and the searching efficiency and the success rate are improved.

Infrared light detection thin film, device and display device and fabrication method of infrared light sensing thin film

The invention provides an infrared light detection thin film, device and display device and a fabrication method of the infrared light sensing thin film. Compared with a device employing a TFT leakagecurrent as an infrared photosensitive thin film transistor, a bottom gate-type field-effect transistor structure is in a way that a photovoltaic gate is arranged in a gap between a source and a drain, the photoelectron simulation is substantially improved. In each detection pixel, the source and the source are connected in parallel, the drain and the drain are also connected in parallel, adjacentsource and drain are in clearance fit, the recombination probability of electrons and holes of optical excitation is reduced, the success probability of the photoelectrons collected by an electrode under a field-effect effect is improved, and the photosensitivity of the TFT leakage current infrared light thin film transistor is improved to the maximum extent. The infrared light detection thin film can be implemented without doping boron-containing gas, the pollution to an environment during the production process of the infrared light detection thin film is effectively reduced, and the production cost is reduced.

The invention belongs to the technical field of rape breeding, and discloses a method for breeding rape by a near-distant hybridization of a cabbagetype rape recessive genic male sterile line. The mothod comprises the following steps of: selecting an original parent: selecting a stable recessive genic male sterile two-line material for the cabbage type rape; selecting a material or variety of Brassica, Cruciferae or more distant relationship for the male parent; carrying out the distant hybridization in an initial flowering period of the recessive genic male sterile line by adopting a twice-pollination method; harvesting hybrid seeds in a mature period, and adopting a seedling raising and transplanting method for a hybrid F1; collecting pollen from F2-F3 generation for microspore culture to obtain hybrid progeny strain material. The method for breeding rape by the near-distant bybridization of the cabbage type rape recessive genic male sterile line effectively reduces bud stripping time of the female parent and reduces the damage to a stigma of the female parent; avoids the influence of the female parent pollen on the hybrid progeny; effectively improves the success probability ofthe hybrid and introduces genes of outer edge species into genome of the cabbage type rape.By the adoption of the method for breeding rape by the near-distant bybridization of the cabbage type rape recessive genic male sterile line,new materials of the cabbage type rape such as early maturing, short stalk, white flower and the like are obtained.

Pressurized leakage-stopping clamp for sand hole on end surface of flange cover and use method

The invention relates to a pressurized leakage-stopping clamp for a sand hole on the end surface of a flange cover and a use method. The pressurized leakage-stopping clamp is characterized in that a cover bowl is fastened at the sand hole of the end surface of the flange cover, a rectangular plate at one end of a pressing plate is arranged above the cover bowl, a round plate at the other end of the pressing plate is fixed on a bolt, a jack screw is screwed on the pressing plate, and rotated clockwise, and the end of a jack screw rod extending out of the pressing plate is closely matched with an opening of an agent injection channel hole of the cover bowl; an agent injection gun is screwed together with a jack screw cap by a pressurized sealing agent injection valve; and the agent injection gun injects a sealing agent, the sealing agent passes through the pressurized sealing agent injection valve, a screw hole II on the jack screw cap, an agent injection channel in the jack screw rod and the agent injection channel hole of the cover bowl in sequence, then enters a cover bowl cavity and is fully injected and compacted, then the agent injection valve is closed and the agent injection gun is removed, so that the purpose of stopping leakage is achieved. The pressurized leakage-stopping clamp and the use method have the advantages that the time of manufacture and construction is greatly saved, the large economic loss caused by stoppage of a continuous chemical production device to a factory is avoided, and even the phenomenon that the life safety of stoppage-leaking operators is endangered sometimes is also avoided.
