By placing a heating source under or around the temperature detector, the temperature change is used to detect the temperature detector.

[0020] See also Figure 1-Figure 4 , a heat-sensing detector detection machine for detecting building fire protection facilities shown in the figure includes a mobile vehicle 101 and a mounting plate 102 connected to the mobile vehicle 101 through a lifting mechanism 103, and also includes a detection mechanism arranged on the mounting plate 102 for performing variable-distance and multi-directional detection of the heat-sensing detector;

[0021] The detection mechanism includes a mounting tube 201 fixedly connected to a side of the mounting plate 102 away from the moving vehicle 101, the other end of the mounting tube 201 is fixedly connected to a circular plate 210, a plurality of L-shaped plates 202 are arranged in a circular array around the circular plate 210, one end of each L-shaped plate 202 away from the mounting plate 102 is fixedly connected to a connecting tube 203, a nozzle 204 is arranged at the opposite end of each connecting tube 203, and the circular plate 210 is provided with a driving mechanism for driving each nozzle 204;

[0022] It should be noted here that: through the setting of the detection mechanism, under the driving action of the driving mechanism, the nozzle 204 is driven to gradually move closer to the temperature detector, thereby realizing variable-distance and multi-directional detection of the temperature detector, which is convenient for simulating the propagation and distribution of heat in space when an actual fire occurs, so that the temperature detector is subjected to unilateral temperature changes, thereby evaluating the response capability of the temperature detector under different conditions and the sensing distance of heat, thereby further improving the accuracy of the detection of the temperature detector.

[0023] It is worth noting that the lifting mechanism 103 can adopt a threaded rod lifting method or a push rod motor and the like, and has various lifting methods in actual use, and no fixed restrictions or unnecessary details are made here.

A plurality of fixed pipes 207 are fixedly connected to the side wall of the mounting pipe 201, and the other end of each fixed pipe 207 is connected to the connecting pipe 203 through a corrugated pipe 208;

[0025] It should be noted here that: by providing the hot air blower 205 , it is convenient to spray the hot air toward one side of the temperature sensor through the nozzle 204 .

[0026] See also Figure 2 , a control valve 209 is provided on the side wall of each fixed pipe 207 shown in the figure;

[0027] It should be noted here that: by setting the control valve 209, it is convenient to individually control each nozzle 204 in different directions, so as to facilitate the multi-directional individual detection of the temperature sensor.

[0028] Working principle: when testing the temperature detector, the mobile vehicle 101 is moved to the bottom of the temperature detector, and then the nozzles 204 on the L-shaped plates 202 are pushed to move closer to the temperature detector under the action of the lifting mechanism 103. When the nozzles 204 are located on the periphery of the temperature detector, the driving mechanism drives the nozzles 204 to move away from the temperature detector.

[0029] After each nozzle 204 is away from one end of the temperature detector, hot air can be supplied to the installation pipe 201 through the hot air blower 205. When one side of the temperature detector needs to be tested, the control valve 209 close to the testing side can be opened to allow the hot air of the hot air blower 205 to flow from the bellows 208 to the nozzle 204, and further pass through the nozzle 204 to spray to one side of the temperature detector. When the hot air is sprayed from the nozzle 204, the driving mechanism and the telescopic component drive the nozzle 204 to gradually move closer to the temperature detector, thereby simulating the actual When a fire occurs, the heat propagates and distributes in space, causing the temperature detector to change on one side, which is used to evaluate the response capability of the temperature detector and the sensing distance of heat under different situations. This helps to reduce the occurrence of false alarms and missed alarms, and improve the accuracy and reliability of fire detection by the temperature detector. After the detection of one side of the temperature detector is completed, the same method can be used to detect other directions of the temperature detector, thereby realizing variable-distance and multi-directional detection of the temperature detector and improving the accuracy of the temperature detector detection.
