This kind of sensor usually has the characteristics of explosion-proof, waterproof and dustproof, and can adapt to the harsh working environment of mine;

[0003] The detection of the mine temperature sensor is the key link to ensure the safe operation of mine equipment, and the sensing precision detection is particularly important. The traditional detection method is to place the sensor in a constant temperature tank, and the precision is verified by comparing the set temperature of the constant temperature tank with the sensing temperature of the sensor. Only one set of comparison data can be obtained at a time, and the reliability and precision are poor. At the same time, this method has certain limitations: the temperature in the constant temperature tank is constant, while the temperature in the actual use environment often fluctuates, so the collection speed and response speed of the sensor under different temperature conditions cannot be comprehensively evaluated;

[0030] Please refer to Figure 1 Figure 6 As shown in the utility model is a kind of mine temperature sensor detection device, including detection box 1, detection box 1 is divided into two parts by horizontal transverse partition 11, and two layers are interconnected at both ends, and the lower end of partition 11 is provided with fan 2 on the side of detection box 1, and the side of partition 11 close to fan 2 is provided with electric heating tube 3 capable of heating the inside of detection box 1, and detection box 1 is provided with multiple detection seats 4 in the inside by driving mechanism 5 and is located at the upper and lower ends of partition 11, and detection box 1 is provided with air groove 12 for air intake and exhaust in the upper and lower parts.

[0031] Among them, detection seat 4 is fixedly provided with terminal block 41, terminal block 41 is respectively connected with electrically connected sensor socket 42 and external wire socket 43, sensor socket 42 is connected with the sensor to be measured, and external wire socket 43 is connected with controller through wire.

[0032] Among them, driving mechanism 5 includes two equal-length screw rods 51 rotatably arranged on the upper and lower ends of partition 11 by support and internally threaded sleeve 52 arranged outside screw rod 51, one end of the two screw rods 51 is synchronously linked through pulley set 53, motor 54 is fixed outside detection box 1, the output end of motor 54 is connected with the other end of upper end screw rod 51 through bevel gear pair, and the cooperation of threaded structure is high in reliability and flexible and stable in movement.

[0033] Among them, detection seat 4 is symmetrically fixed on both sides of internally threaded sleeve 52, and detection seat 4 also slides between detection box 1 and partition 11, and in the embodiment, two detection seats 4 are symmetrically fixed on both sides of internally threaded sleeve 52 to ensure uniform transmission of force, and the sliding contact between detection seat 4 and detection box 1 and partition 11 supports the movement of detection seat 4 and internally threaded sleeve 52, to prevent internally threaded sleeve 52 from rotating after screw rod 51 rotates.

[0034] Among them, dustproof net 7 is fixedly provided outside detection box 1 to cover air groove 12, and in the embodiment, dustproof net 7 can be fixedly attached to the outer side of detection box 1 by means of bolts, buckles and the like, mainly to prevent external dust from entering detection box 1 carried by air flow.

[0035] ​In this embodiment, the air slots 12 are of different sizes and are arranged in an array along the airflow direction inside the detection box 1. Several standard sensors 6 are fixed on the inner side wall of the detection box 1 and are equidistant from the air slots 12. In this embodiment, different air intake and exhaust volumes can be obtained by using air slots 12 of different sizes, thereby forming different temperature ranges inside the detection box 1. The set standard sensors 6 are used to sense the temperature of the corresponding range and then compare it with the sensing data of the sensor under test.

[0036] In this embodiment, the end of the test box 1 away from the heating element 3 is open and a door 13 is hinged at the opening. When the door 13 is opened, the fan 2 stops working and the heating element 3 continues to work to store energy, which can effectively reduce heat loss when the sensor to be tested is replaced. The end of the door 13 away from the hinge can be connected to the test box 1 through a magnetic structure or a quick-locking structure. At the same time, a handle for easy opening and closing is fixed on the outside near the connection side.

[0037] Understandably, a semi-circular channel is formed by setting up partitions inside the detection chamber, and the airflow speed and temperature are regulated by electric heating tubes and fans; air grooves on the channel allow airflow inside and outside to circulate, forming different temperature ranges; multiple standard sensors are arranged along the channel, and after the sensor under test enters, it is moved by a drive mechanism, and the data is compared with that of the standard sensor to detect its accuracy at different temperatures; at the same time, the reaction speed and sensing speed of the sensor are evaluated by the time difference between the drive command and the sensing data, ensuring its reliability in the mining environment.

[0038] One specific application of this embodiment is as follows: the fan 2, the heating element 3, the standard sensor 6, and the motor 54 are connected to the power supply and the controller. The external wiring socket 43 is also connected to the controller. This is used to collect and record the data of the sensor under test. The controller coordinates their work with each other.

[0039] like Figure 1 The detection seat 4 shown is located near the door 13. The sensor under test is then plugged into the sensor socket 42, and the sensor under test is electrically connected to the controller. The door 13 is closed, and the fan 2 and heating element 3 operate simultaneously. The fan 2 drives the airflow inside the detection chamber 1 to flow from the lower end of the partition 11 towards the door 13, and then from the door 13 towards the upper end of the partition 11, before returning to the fan 2 and heating element 3 for circulation. During this process, due to the high airflow velocity at the lower end of the partition 11, external airflow is drawn in through the lower air groove 12. The airflow returning from the upper end of the partition 11 is reversed; some internal airflow is discharged outwards through the upper air groove 12, while the remaining airflow continues to circulate. The specific airflow path is as follows: Figure 4 The arrows shown indicate the direction;

[0040] The motor 54 outputs to drive the screw rod 51 to rotate through the bevel gear set and drive the inner threaded sleeve 52 to translate in the detection box 1, the two screw rods 51 are synchronously linked through the belt wheel set 53, the inner threaded sleeve 52 moves to drive the to-be-detected sensor on the detection seat 4 to move in the detection box 1, each positioning of the to-be-detected sensor is close to the standard sensor 6 at the corresponding position, the data of the corresponding standard sensor 6 and the to-be-detected sensor are collected, then the to-be-detected sensor moves to the standard sensor 6 at other positions, so as to obtain multiple groups of data, and the to-be-detected sensors on the multiple detection seats 4 are synchronously displaced through the driving mechanism 5.
