Description
Technical field
The utility model relates to a kind of temperature control reisilometer, belongs to soil surveying technical field.
Background technology
At present, environment temperature when 3.1.4 bar specifies that reisilometer uses in " concrete intensity with rebound method technical regulation " (JGJ/T23-2011) should be (-4 ~ 40) DEG C, when environment temperature is abnormal, there is impact to the performance of reisilometer, therefore define environment temperature when it uses.But due to engineering detecting environment temperature lower than-4 DEG C time, during as detected in the winter time, in the situation such as freezer detection, in prior art, concrete bouncing back instrument just can not meet the requirement of " concrete intensity with rebound method technical regulation " (JGJ/T23-2011), cannot provide legal quality testing report.Once construction engineering test unit or relevant departments provide quality testing report, just belong to and violate normal running code, do not have legitimacy, quality testing is reported as unreasonable report, even causes legal dispute.Therefore need to improve existing concrete bouncing back instrument, make the working environment that it adapts to lower than-4 DEG C.
Utility model content
The purpose of this utility model is to provide a kind of temperature control reisilometer, to use reisilometer at low temperatures better.
To achieve these goals, the technical solution of the utility model is as follows.
A kind of temperature control reisilometer, comprises metal outer shroud and metallic inner, is provided with anti-hot film and rock wool between metal outer shroud and metallic inner; Metal outer shroud upper right is provided with temperature indicator, rule is provided with on the left of temperature indicator, metal outer shroud right side central is provided with external power supply jack for subsequent use, external power supply jack top and the bottom for subsequent use are provided with battery cavities, battery cavities top is provided with temperature indicator switch, and battery cavities bottom is provided with resistance tap changer.
Further, battery cavities is provided with power lead to be connected with temperature indicator with resistance and temperature inductive coil respectively, temperature indicator switch-linear hybrid is between battery cavities and resistance and temperature inductive coil, and resistance tap changer is arranged between battery cavities and heater coil.
Further, metallic inner inside is provided with multiple resistance and temperature inductive coil, and resistance and temperature inductive coil shape is for adopting spiral hoop shape method for expressing to be L φ 2@20.
Further, metallic inner outer setting has multiple heater coil, and heater coil shape is for adopting spiral hoop shape method for expressing to be L φ 2@20.
In this device, open temperature indicator switch, utilize resistance and temperature inductive coil temperature sensor, temperature is shown by temperature indicator, regulating resistance tap changer, heater coil heats up, when temperature indicator remains on-4 DEG C ~ 40 DEG C, stopping regulating resistance tap changer, is at this moment instrument normal operating conditions, when instrument is in normal operating conditions, overcomes extraneous low temperature and at this moment just solve testing environment lower than the difficult problem that cannot detect concrete strength when-4 DEG C.When electricity is finished in battery cavities, utilizing external power supply jack for subsequent use to connect external power source, is battery cavities charging.
The beneficial effect of this utility model is: the utility model device when testing environment temperature is lower than-4 DEG C, by regulating temperature, controls reisilometer temperature and being not less than-4 DEG C, thus cannot detect a difficult problem for concrete strength when overcoming extraneous low temperature.
