Description

Technical Field

[0001] The utility model relates to the technical field of sensor detection, in particular to a temperature sensor testing device. Background Art

[0002] Temperature sensors are essential sensors in mines and are related to production safety. The "Management Specifications for Coal Mine Safety Monitoring Systems and Testing Instruments" AQ1029-2019 stipulates the installation and calibration of temperature sensors as follows:

[0003] 1. The air compressor should be equipped with a temperature sensor. When the temperature exceeds the limit, an audible and visual alarm will sound and the power supply of the air compressor will be cut off.

[0004] 2. Safety monitoring equipment must be calibrated regularly according to the requirements of the product manual.

[0005] 3. Before use and after overhaul, the safety monitoring equipment must be tested and calibrated according to the requirements of the product manual, and must be tested on the ground for 24 to 48 hours before it can be lowered into the well.

[0006] The previous testing method involved adjusting the sensor's temperature using a remote control according to the product manual. This method only tested the sensor's audible and visual alarm functions and failed to accurately reflect the sensor's sensitivity to ambient temperature, posing a safety hazard. Later, the ground compressor room temperature sensor was tested by burning a candle to heat the sensor element, performing a power-off test for excessive temperature. This method was inefficient and severely damaged the sensor element. Utility Model Content

[0030] like Figure 1-3As shown in Figure 5, a temperature sensor testing device includes a shell 1, a power supply 3, a temperature controller 5 and a heating device 4. The shell 1 is divided into three chambers by a partition 2. The power supply 3, the temperature controller 5 and the heating device 4 are respectively arranged in the three chambers. The temperature controller 5 is electrically connected to the power supply 3 and the heating device 4. A thermocouple connected to the temperature controller 5 is arranged on the heating device 4 to collect the heating temperature of the heating device 4. The control panel on the temperature controller 5 is embedded in the shell 1. The heating device 4 is fixed on the box 1 or the partition 2. A detection hole 6 is provided on the heating device 4, and a through hole 7 coaxial with the detection hole 6 is provided on the shell 1; the shell 1 is divided into different chambers by the partition 2 to achieve isolation between the power supply 3, the heating device 4 and the temperature controller 5, reduce mutual interference and interference from the external environment, ensure stability and safety in use, and solve the problem of low efficiency of existing detection methods.

[0031] The heating device 4 is fixed on the partition 2 or the box to prevent the shaking of the thermocouple from causing instability in the heating area and affecting the detection results. At the same time, a detection hole 6 is provided on the heating device 4, and a through hole 7 corresponding to the detection hole 6 is provided on the shell 1. The sensor to be detected extends into the detection hole 6 through the through hole 7 to reduce the interference of the heating device 4 with the external environment. The setting of the detection hole 6 makes the sensor more evenly heated, thereby ensuring the detection accuracy.

[0032] The heating device 4 is an electric heating rod, and an arc-shaped metal sheet 13 is mounted on the side wall of the electric heating rod, and a detection hole is formed on the side wall of the electric heating rod; the heating rod is fixed to the partition 2 or the box body 1 by a buckle or a clamp, and the arc-shaped metal sheet 13 is used to form a detection hole on the electric heating rod. The thermal conductivity of the metal is used to make the heat around the detection hole 6 uniform, thereby improving the detection accuracy.

[0034] like Figure 4 As shown, this embodiment is obtained by further describing the technical features such as the heating device 4 on the basis of the embodiment one. The remaining technical features are the same as those of the embodiment one, and the similarities are not repeated here. Among them, the difference between this embodiment and the embodiment one is that: the electric heating rod is replaced by an electric heating wire, and the electric heating wire is surrounded into a circular ring structure to form the detection hole.

[0035] In this embodiment, the electric heating wire is fixed to the partition 2 or the box body 1 by screws or clips, and the flexible characteristics of the electric heating wire are used for deformation setting, and the detection hole 6 is formed by its own deformation. Compared with the first embodiment, the structure is simpler and the use of materials is reduced, so that the temperature around the detection hole 6 is more uniform. Example 3

Among them, the difference between this embodiment and Example 2 is that: a display 10 for displaying the power level of the power supply 3 is provided on the shell 1, and a charging port 9 electrically connected to the power supply 3 is provided on the shell 1.

[0037] In this embodiment, a display 10 for displaying the power level and a charging port 9 for charging are provided, which can obtain the power level of the power source 3 in real time, facilitate charging the power source 3 through the charging port 9 according to the situation, and ensure stability of use.

[0038] The usage process of the overall technical solution formed by the above embodiments is as follows: determine the detection temperature of the temperature sensor to be detected, turn on the main switch 11 and the heating switch 12, set the heating temperature of the heating device 4 through the control panel on the temperature controller 5, and display the heating temperature in real time through the display 10. After the heating temperature reaches the set temperature and a stable thermal environment is formed, the temperature sensor to be detected is inserted into the detection hole 6 from the through hole 7 to heat the temperature sensor. After the detection is completed, turn off the heating switch 12, carry this application to the next detection position by the handle, until the detection work is completed, and turn off the main switch 11; the display 10 displays the power of the power supply 3, and when the power is too low, the power supply is charged through the charging port 9.

[0039] The temperature controller 5 , the thermocouple, the heating switch 12 , the main switch 11 and the display 10 may be any commonly used device in the prior art and are not subject to any additional restrictions.
