This invention relates to an underwater self-floating unmanned aerial vehicle (UAV) swarm transport device and its operating process, comprising, from top to bottom, a top cover, an airbag compartment, a main body section, a tail section, and a deceleration parachute compartment. The top cover, main body section, and tail section are all externally covered with deep-sea buoyancy material. A transport device is located inside the main body section, comprising an UAV compartment, a battery compartment, and a control compartment. The UAV compartment carries the UAV system to ensure surface launch. The battery compartment and control compartment are located below the UAV compartment. The battery compartment provides power throughout the process, and the control compartment controls the device's movement and signal transmission and reception. A fixing ring is located at the bottom of the transport device for connecting an acoustic release device and a gravity anchor. This facilitates rapid and reliable transport and ascent of the UAV swarm, stable surface launch of multiple UAVs, and ensures operational reliability.

This utility model relates to the field of deep-sea operation equipment deployment and recovery, and provides an acoustic release device, including a transducer module, a housing, and a release module. The housing is a hollow cylindrical shape, with the transducer module located at the top of the housing and the release module located at the bottom. A tension rod is provided inside the housing, with its two ends fixedly connected to the transducer module and the release module, respectively. The rod body is spaced apart from the inner wall of the housing. The acoustic release device provided by this utility model has a housing that is not easily deformed under tension, which helps to maintain a tight seal inside the housing.

The invention relates to the technical field of bird repelling devices, and discloses a bird repelling forced air gun. The sound wave frequency adjusting valve with multiple valve element pipelines is arranged, the device emits different sound waves by switching the different valve element pipelines, and therefore the continuous and effective bird repelling performance of the device is ensured, meanwhile, the auxiliary pipeline is arranged, and when a bird repelling gun compressed air chamber releases air, the auxiliary pipeline is used for adjusting the sound wave frequency. At the moment, part of gas enters an auxiliary pipeline through an auxiliary gas inlet pipe opening, under the action of pressure, a movable sliding block moves upwards, a sliding block reset spring is extruded and contracted, the extruded gas is discharged through an auxiliary gas outlet pipe opening and mixed with gas in a sound wave release pipeline, and composite differential sound waves are formed; at the moment, under the elastic action of the sliding block reset spring, the movable sliding block moves downwards, internal gas is promoted to be exhausted through the auxiliary gas inlet pipe opening, another characteristic sound wave is formed in the sound wave release pipeline, and meanwhile the lasting time of the sound wave is prolonged.

The disclosed invention relates to a method and system 10 for releasing adherent cells 12 in a cell container 14 with a plurality of acoustic transducers 16a, 16b, 16c, 16h. The method comprises: gene

An example line restraint system comprises a housing, processor, motor, release cam, and a receiver. The release cam comprises a stem portion opposite an arm portion. The arm portion may extend away from the stem portion of the release cam. The stem portion may be rotatably coupled to the motor with the motor being configured to turn the arm portion of the release cam between an open and closed state. When in the closed state, an overhang of the arm portion of the release cam at least partially defining a cavity capable of retaining a release line. When in the open state, the release cam opening the cavity to enable release of the release line. The receiver may be configured to receive an acoustic signal. The processor may be configured to trigger the release cam to turn based on the acoustic signal.

This utility model relates to the field of deep-sea exploration and marine engineering equipment, and provides a buoyancy storage device and an acoustic release system for an acoustic release device. The buoyancy storage device includes a storage tank structure, a float body, and a locking assembly for connecting to the acoustic release device. Both the storage tank structure and the float body have a sleeve structure that can be fitted onto the acoustic release device. The locking assembly includes a first clamping ring and a second clamping ring, which are respectively clamped to both sides of the float body. The first clamping ring has a connection structure for connecting to the acoustic release device, and the second clamping ring is connected to the first clamping ring through an adjustable locking structure. The float body is annular, and the inner ring structure of the float body forms a sleeve structure that can be fitted onto the acoustic release device. The buoyancy storage device and acoustic release system provided by this utility model facilitate a stable connection between the float body and the acoustic release device.

The utility model provides a kind of self-floating type seabed node heavy load release recovery device, it is related to marine environmental monitoring technical field, comprising: acoustic release; floating body component, including frame and float; the lower end of float is connected N crossbeam;Annular counterweight is arranged below floating body component, is equipped with N lifting ring;Seabed node, is arranged inside annular counterweight;Rope assembly, including N counterweight connecting rope and M node connecting rope;Counterweight connecting rope forms U-shaped folding rope after passing through release hook;U-shaped folding rope passes through the outside of crossbeam, free end is connected in lifting ring;M node connecting rope one end is fixedly connected in seabed node, wherein, the other end of a node connecting rope is fixedly connected with the upper end of frame, and the other end of remaining node connecting rope is connected with release hook and automatically separates from release hook in release hook opening state.The utility model alleviates the chain invalidation problem of "attitude out of control-positioning lost connection" after release of existing OBN release recovery device.

The application discloses a layered water sampling device, which comprises a frame body, detachable weights and a float arranged on the frame body, a sampling assembly comprising a plurality of water sampling bottles which are uniformly distributed on the frame body, an automatic unhooking mechanism arranged on the frame body and having a height higher than that of the water sampling bottles and being connected with the water sampling bottles, and a control assembly connected with the automatic unhooking mechanism and the weights and used for controlling the automatic unhooking mechanism and releasing the weights. The components in the application are matched with each other to realize the full-process automation of "depth detection-automatic sampling-sealing-recovery".
