Movable real-time multipoint temperature acquisition device for dam

Abstract

The invention relates to a movable real-time multipoint temperature acquisition device for a dam. The movable real-time multipoint temperature acquisition device for the dam comprises interpolating digital temperature measurement devices 1 arranged in a water inlet pipe and a water outlet pipe of each set of cooling water pipe, digital thermometers 2 embedded in respective points of a concrete block in pouring, a temperature acquisition device 3, and a server 4 used for receiving data collected by the temperature acquisition device 3, wherein the temperature acquisition device 3 comprises a data acquisition line 5, an acquisition control module 6, a power supply 7, a cache module 8, a wireless communication module 9 and a waterproof and moisture-proof case 10 and uploads temperature data to the server 4 wirelessly. According to the movable real-time multipoint temperature acquisition device for the dam, the temperature acquisition device 3 is used for collecting temperature data of concrete, inlet / outlet water and the digital thermometers 2 embedded in respective points of the concrete block, and one temperature acquisition device can access over 128 temperature spots, so that the temperature measurement requirement in the concrete cooling project is satisfied; and meantime the simpleness and the convenience are achieved in wiring, the convenience is brought for installation and the movement, and real-time, fast and accurate temperature measurement is achieved.

Description

technical field [0001] The invention relates to a mobile real-time multi-point temperature acquisition device, in particular to a water-passing heat exchange process for large-volume concrete construction and a mobile real-time multi-point temperature acquisition device for a dam during long-term operation. Background technique [0002] The practice of mass concrete construction in a large number of large-scale hydropower projects shows that when pouring concrete in high-temperature or low-temperature seasons, it is difficult to completely control the temperature of the concrete pouring warehouse at the ideal temperature due to the influence of external conditions such as warehouse entry temperature, solar radiation, severe cold, and water cooling. temperature. In order to make the performance of concrete material develop normally, the concrete temperature must be developed according to the design requirements within the normal age period, that is, the maximum temperature of...

Problems solved by technology

[0004] The technical problem to be solved by the present invention is to provide a mobile real-time multi-point temperature acquisition device for arch dams, which can not only automatically collect the temperature of the heat exchange tubes, realize automatic measurement and data transmission of the temperature of the concrete heat exchange medium, but also be able to follow the construction progress It is convenient to move or fix the device, saving connecting lines and manpower; and by embedding a thermometer inside the concrete, and inserting a temperature measuring device into the water pipe to realize real-time measurement of the internal temperature of the concrete and the water temperature of the inlet and outlet of the water, solving the problem of manual measurement records and Control requires a lot of labor, information feedback is slow and the accuracy is not high, saving time and effort, high measurement accuracy and rapid feedback, timely adjustment of concrete temperature control measures, avoiding concrete cracks, and ensuring project quality and progress
