Problems solved by technology
[0004] The commonly used cooling method is to cool with a wet towel or running water. The operation is simple, but the temperature of the connecting rod cannot be well controlled, and the amount of water used and the timing cannot be accurately grasped, and the cooling effect cannot be well controlled.
[0005] At present, in the domestic market, there is no device that can effectively cool down and protect the instrument from damage during the welding and installation process of the steel bar meter, and at the same time realize automatic cooling in real time according to the temperature of the monitoring instrument.

Embodiment
[0042] It is assumed that the steel bar meter used in the project is a vibrating wire steel bar meter, which is fixed with the steel bar to be measured by butt welding.
[0043] Firstly, according to the specifications of the steel bar meter, process a suitable cooling box 1-1 to ensure that the size of the cooling box 1-1, the steel bar meter connecting rod hole 2-8 and the steel bar meter wire hole 2-10 reserved by the cooling box 1-1 are all pasted. Corresponding parameters of steel bars used in joint projects.
[0044] Place the steel bar meter in the cooling box 1-1, connect the steel bar meter connecting rod 1-6, the steel bar meter wire 1-7 along the steel bar meter connecting rod hole 2-8, and the steel bar meter wire hole reserved in the cooling box 1-1 2-10 extends to the outside of the cooling box 1-1, and fastens the lock 2-4 on the box body 2-1 to the box cover 2-2.
[0045] Fix the two temperature control switches 1-3 respectively on the steel bar meter connecti...

The invention discloses a cooling protection device for a steel bar meter. The cooling protection device comprises a cooling box, a water pump, a water storage tank, two temperature control switches, two sections of water pipes and the like, wherein the cooling box is fixed on the steel bar meter during welding operation, the two temperature control switches are fixed on connecting rods at the two ends of the steel bar meter, the water storage tank is a water storage device of the cooling protection device, the water pump is arranged in the water storage tank, and a water outlet of the water pump is connected with a water inlet in the cooling box through a water pipe. When the temperature of the connecting rods of the steel bar meter reaches the set temperature, the temperature control switches are connected, a circuit is connected, the water pump starts to supply water to the cooling box, and the steel bar meter is cooled and protected through running water; and when the temperature of the connecting rods drops below the set temperature, the temperature control switches are disconnected, and the device stops water supplying and cooling. The cooling protection device carries out automatic cooling protection according to the temperature of an instrument, and has a better cooling protection effect compared with a traditional mode.
Description
technical field [0001] The invention specifically relates to a steel bar meter cooling protection device. Background technique [0002] Safety monitoring is one of the important guarantee conditions to ensure the safety of the project. As a monitoring instrument used to measure the stress of steel bars in reinforced concrete, the steel bar meter is an important link to ensure safety monitoring. [0003] At present, the conventional installation method of the steel bar meter is to weld with the steel bar to be tested by butt welding, and to determine the stress on the steel bar by measuring the average strain of a length of the steel bar. However, the high temperature generated during the welding process will increase the zero drift of the steel bar meter, so effective cooling measures must be taken to protect the steel bar meter. [0004] The commonly used cooling method is to cool with a wet towel or running water. The operation is simple, but the temperature of the connec...
