A new packaging structure of fiber optic hydrophone probe and fiber optic hydrophone array, including shell, polyurea composite material, armored optical cable, pressure plate joint, transition connection sleeve, Kevlar rope, acoustic sensor, etc. The shell is the pressure-resistant package of the acoustic sensor, which takes into account the pressure resistance and sound permeability of the probe. Polyurea composite material is a watertight packaging material with excellent water repellency and sound permeability. When multi-probes are in an array, the connection package adopts armored optical cables to protect the optical fibers between the probes, and has good watertight and mechanical properties. The two ends of the acoustic sensor are connected to the armored optical cable through the pressure plate joint, and the outer part of the pressure plate joint is covered with a transition sleeve for sealing. There are a number of fixing holes on the connection sleeve, which are used to fix the Kevlar rope and improve the tensile strength of the array detection cable. strength. Compared with the prior art, the invention has high structural reliability, good water tightness, strong deep water pressure resistance, and easy engineering and mass assembly.

The invention provides a sleep product which is used for solving the problem that a monitoring device is low in monitoring accuracy. The sleep product comprises a sleep product body, at least two fixing devices, and a monitoring device; the sleep product body is provided with a first groove; the fixing devices are fixed to different positions of the monitoring device respectively; and the monitoring device is fixed in the first groove through the fixing devices, so that the monitoring device is fixed in the first groove in an undeformed state.

The invention discloses a coal-fired boiler flame detector with heat conduction induction, which comprises a casing and an induction probe. A groove is opened at one end of the casing, and the induction probe is fixedly connected with the bottom surface wall inside the groove. The bottom surface wall is spirally connected with a threaded driving rod, and the inside of the threaded driving rod is rotatably connected with a support rod, and one end of the support rod extends to the outside of the casing and is fixedly connected with a protective cover. In the present invention, the induction probe is arranged inside the groove, so that the induction probe is not easy to be damaged by impact. During the use of the induction probe, the threaded driving rod is rotated to drive the sliding column to slide into the bar-shaped chute, so that the protective cover and the induction The probes are kept at a certain distance, which has good protection performance and has no barriers to the detection of the probes, which does not affect the detection effect. At the same time, the protective cover can be stored in the groove to prevent the cooling water from entering the sensing probe during maintenance and damaging the sensing probe.

The invention relates to a circuit breaker used for providing overload and short-circuit protection for electric circuits and electrical appliances, in particular relating to a bipolar circuit breaker. The technical scheme provided by the invention is as follows: the bipolar circuit breaker is characterized in that a tripping mechanism comprises a rotating wheel, a tripping frame, a sudden jump frame, a rotating shaft of the sudden jump frame, a spring of the tripping frame, a position-limiting rotating shaft, a tripping plate and a torsion spring, wherein a tension spring is arranged in the rotating wheel and a housing of the tripping mechanism, convex columns are arranged on two sides of the rotating wheel, moving contacts are sheathed on the convex columns, one end of the torsion spring is clamped on the moving contact, and the other end of the torsion spring is clamped on the rotating wheel. By adopting the scheme, the invention provides the novel bipolar circuit breaker which is simple in structure and can enable the pressure between contact points to meet the requirements of the circuit breaker in circuit environments with different current intensities; and furthermore, the tripping force of the tripping mechanism does not change, the sensitivity of the circuit breaker is not affected, and the universality is wide.
