The utility model relates to the technical field of wooden bridge opening plates, and discloses an anti-deformation wooden bridge opening plate with a multi-layer composite structure, which comprises a center plate, an upper side plate is arranged on one side of the outer surface of the center plate, and an upper side protection plate is arranged on one side of the outer surface of the upper side plate. A lower side plate is arranged on the side, away from the outer surface of the upper side plate, of the outer surface of the center plate, a lower side protection plate is arranged on one side of the outer surface of the lower side plate, a center shaft rod is arranged on one side of the outer surface of the center plate, the upper side plate comprises upper side filler, a buffer block is arranged in the upper side filler, and the lower side plate comprises lower side filler. And a sound insulation plate is arranged in the lower side filler. According to the utility model, the plurality of central shaft rods are arranged in the device, the plurality of central shaft rods are uniformly arranged in the central plate, and the central shaft rods are made of wood structures, so that when the plate is stressed, a certain supporting effect can be started, and the deformation is prevented.

This invention provides a cable partial discharge noise signal monitoring device, relating to the field of power equipment condition monitoring technology. It includes: a bottom housing with a set of bolt mounting holes on its side; a top housing mounted on the top of the bottom housing; a set of locking pins mounted on the sides of both the bottom and top housings; a support plate on the side of the top housing; an electric motor mounted on one side of the support plate; and a driven shaft mounted on one side of the top housing. A threaded rod cooperates with a self-locking clamping seat to achieve symmetrical clamping and self-locking of the cable, preventing cable displacement. The greater the tensile force of the cable, the more stable the clamping seat's grip on the cable. An inflatable airbag flexibly conforms to the cable, achieving centering and sealing, preventing dust from entering the cable monitoring area. The airbag also has a sound insulation effect, preventing external vibrations from affecting cable monitoring and avoiding damage to the insulation layer.
