[0022] like Figure 1-4 The portable fire extinguisher spray performance testing device shown includes a mounting plate 1, a cylinder mounting seat 2 on the mounting plate 1, a cylinder 3 on the cylinder mounting seat 2, a pressure block 4 at the output end of the cylinder 3, a fire extinguisher lifting handle support frame 5 on the mounting plate 1 below the pressure block 4, a nozzle fixing assembly at the top of the mounting plate 1, an auxiliary air jet pipe 11 on the nozzle fixing assembly, and a fire extinguisher cylinder support assembly below the fire extinguisher lifting handle support frame 5, which is located at the bottom of the mounting plate 1. It should be noted that the fire extinguisher lifting handle is placed on the fire extinguisher lifting handle support frame 5. When the cylinder 3 operates, pressing the pressure block 4 down to the desired working position, the cylinder 3 stops operating, and the fire extinguisher is in the open spraying state.
[0023] Specifically, the nozzle fixing assembly includes a top rod 6, which is located at the top of the mounting plate 1. A connecting sleeve 16 is slidably mounted on the end of the top rod 6 away from the mounting plate 1. The top of the connecting sleeve 16 is connected to the top rod 6 by a locking bolt 17. A connecting plate 7 is located at the bottom of the connecting sleeve 16, and a retaining ring 8 is located at the bottom of the connecting plate 7. A locking knob 9 is located on the retaining ring 8, and an auxiliary proximity switch 10 is located next to the retaining ring 8. An auxiliary air jet pipe 11 is located next to the auxiliary proximity switch 10. It should be noted that the fire extinguisher nozzle is installed inside the retaining ring 8 and locked in place by the locking knob 9. At the same time, the position of the connecting sleeve 16 on the top rod 6 can be slid as needed and fixed by the locking bolt 17, thus making the device suitable for fixing fire extinguishers of different sizes.
[0024] Specifically, the fire extinguisher cylinder support assembly includes a fire extinguisher cylinder support frame 12, an adjusting screw 13 on the support frame 12, and a fire extinguisher positioning magnetic block 14 at the end of the support frame 12 furthest from the mounting plate 1. It should be noted that the fire extinguisher cylinder support assembly is designed to provide quick positioning and support for fire extinguishers of different sizes, eliminating the need for manual positioning and meeting experimental requirements.
[0025] Specifically, mounting plate 1 is mounted on electronic scale 15, electronic scale 15 is mounted on frame 18, and locking casters 19 are installed at the bottom of frame 18. A computer and touch screen are housed inside frame 18. It should be noted that the locking casters 19 can be used to move the device to the desired work site as needed to meet usage requirements.
[0026] Specifically, the fire extinguisher cylinder support frame 12 consists of a fixed plate, a scissor-type support frame, and a movable plate. One end of the scissor-type support frame is mounted on the fixed plate, which is connected to the mounting plate 1. The other end of the scissor-type support frame has a movable plate, which is connected to the fire extinguisher cylinder via a fire extinguisher positioning magnetic block 14. An adjusting screw 13 is mounted on the scissor-type support frame. It should be noted that its working principle is the same as that of a hoist; when the adjusting screw 13 rotates forward, the scissor-type support frame retracts, and vice versa, thereby adjusting the fixed position of the fire extinguisher cylinder to accommodate fire extinguishers of different sizes.
[0027] The working principle of this specific implementation is as follows: First, adjust the working positions of the connecting sleeve 16, connecting plate 7, and fire extinguisher bottle support frame 12 according to the size of the fire extinguisher. Then, place the fire extinguisher lifting handle on the fire extinguisher lifting handle support frame 5, and simultaneously place the fire extinguisher bottle at the fire extinguisher positioning magnetic block 14. At this time, the fire extinguisher bottle is in an upright state. Then, insert the nozzle into the retaining ring 8 and lock it in place by locking knob 9. When a spray test is required, pull out the fire extinguisher safety pin, and the cylinder 3 works to press down the pressure block 4 on the lifting handle, thereby putting the fire extinguisher in the open spray state. The auxiliary proximity switch 10 senses the spray and starts the subsequent test. After the test is completed, the cylinder 3 resets, moving the pressure block 4 away from the lifting handle. Open the retaining ring 8, take out the nozzle, and remove the fire extinguisher from the fire extinguisher lifting handle support frame 5. At the same time, the auxiliary air spray pipe 11 sprays air to clean the auxiliary proximity switch 10, facilitating subsequent work.
[0028] This invention is not limited to the specific embodiments described above. This invention extends to any new feature or combination disclosed in this specification, as well as any new method or process step or combination disclosed herein.
