[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] See also Figure 1-3 In this embodiment, a device for detecting the sensitivity of a dry powder fire extinguisher includes a carrying mechanism, a testing mechanism is arranged on the top of the carrying mechanism, and a positioning mechanism is arranged on the top of the carrying mechanism.

[0020] In this embodiment, the testing mechanism includes a support frame 2 and a collection box 4. The support frame 2 is fixedly installed on the top of the supporting mechanism. A maintenance door 3 is embedded on the front of the support frame 2. The collection box 4 is placed on the top of the supporting mechanism. The collection box 4 is located on the rear side of the maintenance door 3. Linear modules 5 are fixedly installed on the left and right sides of the inner wall of the support frame 2. A fixed cylinder 6 is fixedly installed on the output end of the linear module 5. A clamping plate 7 is fixedly installed on the output end of the fixed cylinder 6. A detection cylinder 8 is fixedly installed on the top of the support frame 2. The detection cylinder 8 penetrates and extends to the interior of the support frame 2. A pressure sensor 9 is fixedly installed on the output end of the detection cylinder 8. A camera 10 is fixedly installed on the inner top wall of the support frame 2.

[0021] It should be noted that the provision of the collection box 4 and the maintenance door 3 allows the dry powder sprayed from the dry powder fire extinguisher to be conveniently collected and removed, thereby avoiding the difficulty in cleaning the residue inside the entire device.

[0022] Specifically, after the carrying mechanism transports the dry powder fire extinguisher between the two clamping plates 7, the fixing cylinder 6 is started to extend the clamping plate 7 to clamp and fix the dry powder fire extinguisher, and then the linear module 5 is started to drive the fixed dry powder fire extinguisher handle to move to the bottom of the pressure sensor 9, and the detection cylinder 8 is started to drive the pressure sensor 9 to move downward to gently press the dry powder fire extinguisher handle, and transmit the data to the carrying mechanism. At the same time, the camera 10 takes a picture of the hose nozzle connected to the outside of the dry powder fire extinguisher, and transmits the camera data to the carrying mechanism, so that the carrying mechanism compares the downward pressure data with the preset data to know whether the dry powder fire extinguisher handle is sensitive. At the same time, the time data of the dry powder spraying out of the hose nozzle at the moment the pressure plate is pressed is compared with the preset time difference to see whether the dry powder spraying time is accurate, and further judge whether the dry powder fire extinguisher handle is sensitive, so as to make the detection data more accurate and the dry powder fire extinguisher detection continuity better.

[0023] In this embodiment, the supporting mechanism includes a base 1, a control panel 11 is fixedly installed on the back of the base 1, two conveyors 12 are fixedly installed on the top of the base 1, a partition 18 extending to the top of the left conveyor 12 is fixedly installed on the left side of the base 1, the conveyor 12 extends to the interior of the support frame 2, the collecting box 4 is located between the two conveyors 12, the detection cylinder 8 is located above the collecting box 4, and the camera 10 is located on the rear side of the detection cylinder 8.

[0024] The collecting box 4 is placed on the top of the base 1, so that the collecting box 4 can be easily detached.

[0025] Specifically, the right conveyor 12 transports the dry powder fire extinguisher. When the test organization completes the test, the left conveyor 12 sends out the dry powder fire extinguisher. At the same time, when the dry powder fire extinguisher fails the test sensitivity, the two clamping plates 7 are loosened, and one of the fixed cylinders 6 extends to push the dry powder fire extinguisher to one side of the partition 18. The qualified products are extended through the other fixed cylinder 6 to push the dry powder fire extinguisher to the other side of the partition 18, thereby realizing the rapid screening of dry powder fire extinguishers.

[0026] In this embodiment, the positioning mechanism includes a U-shaped support rod 13, the number of which is two, and the U-shaped support rods 13 are fixedly installed on the top of the base 1. The two U-shaped support rods 13 are respectively located on the front and rear sides of the right conveyor 12. Two fixing blocks 14 are fixedly installed on the outside of the U-shaped support rod 13, and an adjusting rod 15 is inserted into the inside of the fixing block 14. The back side of the front adjusting rod 15 and the front side of the rear adjusting rod 15 are fixedly installed with a limiting plate 16. The bottom thread of the fixing block 14 is threaded with a hand-tightening bolt 17, which passes through and extends into the inside of the fixing block 14 and contacts with the adjusting rod 15.

[0027] Specifically, before dry powder fire extinguishers of different types are input through the right conveyor 12, the hand-tightening bolt 17 is rotated according to the model of the dry powder fire extinguisher so that it no longer fixes the adjusting rod 15 inside the fixed block 14, and then the front and rear adjusting rods 15 are moved oppositely or relative to each other inside the fixed block 14. After reaching the specified position, the hand-tightening bolt 17 is rotated to tighten it, so as to adjust the distance between the limit plates 16, so that the transportation of dry powder fire extinguishers of different types is always in the middle position, thereby realizing the normal operation of the testing mechanism.
