Abstract

The invention relates to the technical field of mechanical parts, and specifically discloses an expansive check bolt kit for an ocean buoy. The expansive check bolt kit for the ocean buoy comprises abolt and a nut, wherein the bolt comprises a screw rod and a rod head located at the top end of the screw rod; and the tail end of the screw rod is provided with a spiral thread. The expansive check bolt kit for the ocean buoy further comprises a sleeve provided with a plurality of straight-line joints, and a flat gasket located between the sleeve and the nut; the cross section from the top end tothe tail end, of the screw rod, is gradually reduced; an opening matched with the screw rod is formed in the flat gasket; a plurality of blind holes are formed around a screw hole of the nut; a spring is installed in each blind hole; and the free length of each spring is greater than the depth of the corresponding blind hole. The expansive check bolt kit for the ocean buoy is capable of fasteninga part to be fastened or a part to be connected on the ocean buoy in a long-lasting manner, not liable to loose, and convenient to detach.

Description

technical field [0001] The invention relates to the technical field of mechanical parts, and more specifically, to an expansion type anti-loosening bolt kit for marine buoys. Background technique [0002] The ocean buoy is an automatic ocean hydrological, water quality and meteorological observation station composed of observation buoys anchored at sea. It is a safety warning device that is required for platforms (ships) operating in offshore oil / gas extraction areas. The platform is located 10 to 40 nautical miles away, providing real-time information such as ocean internal waves, sea surface meteorology (wind speed and direction, temperature and humidity, etc.), ocean hydrology (wave height and wave direction, current velocity and direction, etc.) for offshore oil operation platforms (ships) , for the safe operation reference of the platform (ship). Ocean buoys can collect the required marine hydrology, water quality and meteorological data for marine scientific research,...
