Problems solved by technology

This patent can reproduce the phenomenon of liquid surface splashing at the natural frequency, but it also does not mention the influence of additional acceleration in the direction of gravity
[0005] To sum up, a variety of motion platforms and experimental systems have been used in thermal-hydraulic research under ocean conditions, but researchers seldom consider the external excitation of additional acceleration in the direction of gravity, which seems to have a simple mechanism but actually has a wide range of influences.

Embodiment Construction

[0024] The present invention is described in more detail below in conjunction with accompanying drawing example:

[0025] to combine figure 1 , the present invention includes a power input part and a power output part, the power input part includes a high-power motor 6, a crank mechanism 7, a gear reduction box 8; the power output part includes 2 traction ropes 2 (wire ropes), a stainless steel pulley 1, and an overall frame 3 , sports platform 4, triangular rib 5. The power output part of the present invention works according to the principle that the high-power motor 6 is connected to the gear reduction box 8, and the gear reduction box 8 is connected to the crank mechanism 7 again. The gear reducer refers to the reducer matched with the high-power motor. The gear reducer is an independent closed transmission device between the prime mover and the working machine, which is used to reduce the speed and increase the torque to meet the work needs. The present invention calcul...

Abstract

The invention aims to provide a simple system for simulating fluctuating motion under ocean conditions, the simple system comprises a power input part and a power output part, the power input part comprises a high-power motor 6, a gear reducer 8, a crank mechanism 7 and a base 13, and the power output part comprises an integral frame 3, a motion platform 4, a triangular rib 5, a support structure 15, four stainless steel pulleys 1 and a traction rope 2. The invention aims to provide a motion system which is wide in research working condition, convenient in instrument mounting and free of other interference on an experiment body, and is used for real-time measuring of parameters such as liquid level of a reactor liquid container, impact load on a side wall surface, flow of a simple loop and pressure drop under the condition of reproducing fluctuation. The system is low in cost, convenient to build and simple to operate.

Description

technical field [0001] The invention belongs to the technical field of response to thermal and hydraulic characteristics under ocean conditions, and in particular relates to a simple system for simulating ups and downs under ocean conditions. Background technique [0002] For nuclear power plants working on land, due to the possible impact of earthquakes, wind waves, tsunamis, etc., equipment such as pressurizers and steam generators with free liquid surfaces will experience severe sloshing. The sloshing phenomenon will lead to violent fluctuations in the free liquid surface. On the one hand, these fluctuating free liquid surfaces will have a mechanical impact on the wall of the container and the equipment in the container, threatening the structural stability. On the other hand, the fluctuating free liquid surface will also produce complex fluid flow mechanical phenomenon. The root cause of these phenomena is the additional acceleration introduced by ocean conditions. Unde...
