Figures 1-4 This utility model provides a technical solution: a sampling gun for LDAR leak detection equipment, including a detector body 1, a filtering mechanism 2 provided on the top surface of the detector body 1, and a storage mechanism 3 provided on the left side of the detector body 1;

[0029] The filtration mechanism 2 includes a sampling section 21 and a filtration section 22;

[0030] The filter section 22 is located on the inner side of the sampling section 21;

[0031] The storage mechanism 3 includes a fixing part 31 and a storage part 32;

[0032] The storage section 32 is located on the inner side of the fixing section 31.

[0033] The sampling unit 21 includes a filter box 211, which is connected to the detector body 1. A sealing door is hinged to the front side of the filter box 211. A handle 212 is provided on the top surface of the filter box 211 and is fixedly connected to the filter box 211. An air pump 213 is provided on the left side of the handle 212 and is connected to the filter box 211.

[0034] A flexible tube 214 is connected to the top surface of the air pump 213, a grip tube 215 is connected to the top surface of the flexible tube 214, and a retainer 216 is connected to the top surface of the grip tube 215. The retainer 216 and the sampling tube 217 are engaged with each other.

[0035] The filter section 22 includes a filter sponge 221, which is located on the inner side of the filter box 211. The outer side of the filter sponge 221 is provided with a sliding groove 222, which is fixedly connected to the inner side of the filter box 211 and slidably connected to the filter sponge 221. The inner side of the sliding groove 222 is provided with a sliding groove.

[0036] A pull rod 223 is provided through the inner wall of the slide groove 222. The pull rod 223 is slidably connected to the inner wall of the slide groove 222. A pressure plate 224 is provided on the bottom surface of the pull rod 223. The pressure plate 224 is fixedly connected to the pull rod 223. A slider 225 is provided on the outer side of the pressure plate 224. The slider 225 is fixedly connected to the pressure plate 224. A return spring 226 is provided above the slider 225. The return spring 226 is fixedly connected to the pressure plate 224 and the inner side of the slide groove 222.

[0037] Furthermore, in this embodiment, the sampling tube 217 in the sampling section 21 is selected through the filtration mechanism 2. A suitable sampling tube 217 is selected and secured with the retainer 216. Then, the vacuum pump 213 is activated, forming a vacuum passage through the hose 214, the grip tube 215, and the sampling tube 217. The vacuum pump 213 extracts gas from the leak detection location through the sampling tube 217. The extracted gas passes sequentially through the sampling tube 217, the grip tube 215, and the hose 214 into the filter box 211, where it passes through the filter sponge 221. The filter sponge 221 adsorbs impurities in the gas, and the purified gas enters the detector body 1. When the filter sponge 221 needs to be replaced, open the sealing door plate and pull the lever 223. The lever 223 drives the pressure plate 224 to slide along the inner side of the sliding groove under the action of the slider 225. During the sliding process, the pressure plate 224 squeezes the reset spring 226, causing the filter sponge 221 to separate from the pressure plate 224, the old filter sponge 221 is pulled out, and the new filter sponge 221 is placed in the sliding groove 222. Release the lever 223, the reset spring 226 resets, and pushes the pressure plate 224 to fix the new filter sponge 221, ensuring that the air sample entering the detection chamber is relatively clean and protecting the normal operation of the detector body 1.

[0038] Furthermore, in this embodiment, the sampling tube 217 in the sampling section 21 is selected and engaged with the sleeve 216 through the filtering mechanism 2. After engagement, the vacuum pump 213 is started. The vacuum pump 213 extracts the leak detection location through the hose 214, the grip tube 215 and the sampling tube 217. The extracted material enters the filter box 211 through the sampling tube 217, the grip tube 215, the hose 214 and the vacuum pump 213. Then it is adsorbed by the filter sponge 221 and enters the detector body 1. When the filter sponge 221 needs to be replaced, the sealing door is opened and the pull rod 223 is pulled. The pull rod 223 drives the pressure plate 224 to slide on the inner side of the sliding groove under the action of the slider 225, thereby squeezing the reset spring 226 and thus pulling out the filter sponge 221. After removal, the new one is placed in the sliding groove 222, and then the reset spring 226 is loosened to reset.

[0039] Example 2:

[0040] Please see Figure 1 , Figure 2 , Figure 5 Furthermore, based on Embodiment 1, the fixing part 31 includes a U-shaped plate 311, which is fixedly connected to the detector body 1. An installation groove is provided on the inner side of the U-shaped plate 311. A handle 312 is provided on the front side of the U-shaped plate 311. A threaded rod 313 is provided on the rear end face of the handle 312. The threaded rod 313 is fixedly connected to the handle 312. The threaded rod 313 extends through to the inner side of the installation groove. The rear end face of the threaded rod 313 is rotatably connected to the inner side of the installation groove through a bearing seat.

[0041] The storage section 32 includes a threaded block 321, which is threadedly connected to a threaded rod 313. A fixing plate 322 is provided on the left side of the threaded block 321, which is fixedly connected to the threaded block 321. A clamping plate 323 is provided on the rear side of the fixing plate 322, which is fixedly connected to a U-shaped plate 311.

[0042] Furthermore, in this embodiment, through the storage mechanism 3, the card plate 323 in the storage part 32 allows the operator to place the grip tube 215 on the card plate 323 after the sampling work is completed. The operator rotates the handle 312, which drives the threaded rod 313 to rotate together. The rotation of the threaded rod 313 causes the threaded block 321 to move along the axial direction of the threaded rod 313. When the threaded block 321 moves, it drives the fixed plate 322 connected to it to move together. After the fixed plate 322 moves, it will squeeze or limit the grip tube 215 placed on the card plate 323.

[0043] Furthermore, in this embodiment, through the storage mechanism 3, the card plate 323 in the storage part 32 is used. After sampling, the grip tube 215 is placed on the card plate 323, the handle 312 is rotated, the handle 312 drives the threaded rod 313, the threaded rod 313 drives the threaded block 321, and the threaded block 321 drives the fixing plate 322 to fix the grip tube 215. Whether in the laboratory, in the field or in other complex working environments, it can work stably and reliably, ensuring the storage and fixing effect of the grip tube.

[0044] In use, the sampling tube 217 in the sampling section 21 is selected through the filtration mechanism 2, and then locked in place with the retainer 216. The vacuum pump 213 is then started, forming a suction path through the hose 214, grip tube 215, and sampling tube 217. The vacuum pump 213 extracts gas from the leak detection location through the sampling tube 217. The extracted gas passes sequentially through the sampling tube 217, grip tube 215, and hose 214 into the filter box 211, passing through the filter sponge 221. The filter sponge 221 adsorbs impurities in the gas, and the purified gas enters the detector body 1. When the filter sponge 221 needs to be replaced, the sealing door is opened, and the lever 223 is pulled. The lever 223 causes the pressure plate 224 to slide along the inner side of the sliding groove under the action of the slider 225. During the sliding process, the pressure plate 224 squeezes the reset spring 226, causing the filter sponge 221 to contact the pressure plate. 224 Separation: The old filter sponge 221 is removed, and the new filter sponge 221 is placed in the slide groove 222. The pull rod 223 is released, the reset spring 226 is reset, and the pressure plate 224 is pushed to fix the new filter sponge 221, ensuring that the air sample entering the detection chamber is relatively clean and protecting the normal operation of the detector body 1. Through the storage mechanism 3, using the card plate 323 in the storage part 32, after the sampling work is completed, the operator places the grip tube 215 on the card plate 323. The operator rotates the handle 312, and the rotation of the handle 312 will drive the threaded rod 313 to rotate together. The rotation of the threaded rod 313 will cause the threaded block 321 to move along the axial direction of the threaded rod 313. When the threaded block 321 moves, it will drive the fixed plate 322 connected to it to move together. After the fixed plate 322 moves, it will squeeze or limit the grip tube 215 placed on the card plate 323.
