Abstract

The invention discloses an underwater movable measuring device for measuring the high-temperature steam spraying condensation temperature, and the device comprises a first sliding rail and a first sliding block which are in sliding connection, wherein the first sliding block is provided with a measurer; a first driving mechanism and a first transmission mechanism, wherein the first driving mechanism is in power coupling connection with the first transmission mechanism, and the first transmission mechanism is connected with the first sliding block; a second sliding rail and a second sliding block which are connected in a sliding mode, wherein the second sliding block is fixedly connected with the first sliding rail; and a second driving mechanism and a second transmission mechanism, whereinthe second driving mechanism is in power coupling connection with the second transmission mechanism, and the second transmission mechanism is connected with the second sliding block. According to themeasuring device, a multi-dimensional movable measuring scheme is provided, measuring points can be greatly reduced, the arrangement difficulty is reduced, the cost is saved, the measuring device canbe moved out of the steam plume, and the flow pattern of the steam plume can be conveniently and accurately recorded.

Description

technical field [0001] The application belongs to the technical field of thermal hydraulic manufacturing of reactors, in particular, it relates to an underwater movable measuring device for measuring the condensation temperature of high-temperature steam spraying. Background technique [0002] High-temperature and high-pressure steam will form a steam plume when it is sprayed underwater. For the underwater spraying process of high-temperature and high-pressure steam, it is difficult to measure the temperature distribution of steam plume due to the harsh and complex environment. Especially for reactor depressurization, steam plumes will be formed at multiple nozzles in the pipeline. In the related technology, in order to measure the temperature distribution of each steam plume, quite a lot of temperature measurement units need to be arranged, with many measuring points, complicated installation and arrangement, too many thermocouple lead-out wires, and these temperature measu...
