Problems solved by technology

[0006] The flexible tarpaulin needs to bear a certain water pressure. When the height of the pool water is high, the flexible tarpaulin needs to withstand a large downward pressure. The requirement for the tensile strength of the flexible tarpaulin is high, and it is easy to damage and has a long service life. lower

Abstract

The invention relates to an underwater vibrating system and a universal transmission device thereof, and relates to the field of underwater vibrating test equipment. The waterproof sealing purpose ofan underwater vibrating table is mainly achieved, and the durability and reliability are improved. According to the technical scheme, the universal transmission device of the underwater vibrating system comprises a universal transmission component and a flexible waterproof sleeve, the flexible waterproof sleeve is arranged on a base in a sleeving mode, an opening in the first end of the flexible waterproof sleeve is connected with a first universal transmission joint in a sealed mode, and an opening in the second end of the flexible waterproof sleeve is connected with a second universal transmission joint in a sealed mode; and a sealing waterproof space for containing the base, a first rotating shaft and a second rotating shaft is formed in the flexible waterproof sleeve. Compared with theprior art, flexible waterproof cloth does not need to be used for sealing at the circumferential gap between a vibrating circular truncated cone and a pit, the risk that the flexible waterproof clothis damaged due to the fact that the flexible waterproof cloth bears large downward pressure intensity is avoided, and the service life of the underwater vibrating system is prolonged.

Description

technical field [0001] The invention relates to the field of underwater vibration test equipment, in particular to an underwater vibration system and a universal transmission device thereof. Background technique [0002] The underwater vibrating table is mainly a device for testing underwater structures. The underwater components such as bridge pier foundations and dams are different from the application of traditional above-ground components. Therefore, special underwater The vibration table is used to carry out vibration tests under water to verify the anti-seismic performance indicators of underwater component specimens in water. [0003] The current underwater vibrating table mainly includes a test pool, a vibrating round table, and hydraulic supporting equipment for driving the vibrating round table to vibrate. The bottom of the test pool has a pit, and the vibrating round table is in the pit. The hydraulic cylinder of the hydraulic supporting equipment inputs the vibr...
