Abstract

The invention discloses a cooling tower collapse analog experiment device, which comprises a cooling tower model, a data acquiring device, a data processing device, a plurality of support posts, a pedestal and a post support device, wherein the data acquiring device is connected with the data processing device; a part of the bottom of the cooling tower model is supported on the pedestal through the plurality of support posts; the other part of the cooling tower model is supported through the support device; the height of the support device can be adjusted; the data acquiring device is arranged in front of / vertical to the collapse direction of the cooling tower model; both the cooling tower model and the support posts are formed by casting mortar and steel bars; and the compressive strength of mortar is consistent with the practical compressive strength of a cooling tower. A physical model of a cooling tower established by using mortar and steel bars which have the same practical engineering performance as the cooling tower is utilized, the structural mechanics are matched with the practical engineering of the cooling tower, and the form of the collapsed cooling tower model is obtained through testing, so that the practical safety coefficient of the cooling tower is increased.

Description

technical field [0001] The invention relates to a simulation test device, in particular to a cooling tower collapse simulation test device. Background technique [0002] In the secondary circulation cooling system of the nuclear power project, a cooling tower needs to be installed as a place where the circulating water and the cooling medium exchange heat, take away the heat and lower the temperature. Due to the large capacity of a single nuclear power unit, the amount of circulating water is also relatively large, so the geometric volume of the cooling tower is also quite large. According to the existing industry knowledge, the cooling tower of a 1000MW class nuclear power plant generally needs to reach a height of more than 200m and a zero-meter diameter of more than 180m. Nuclear power cooling towers generally adopt a hyperbolic reinforced concrete structure. The super-large cooling tower structure is mainly divided into four structural parts: foundation, pillar, tower ...
