[0002] When sampling barreled liquid, to ensure the representativeness of the sample and the accuracy of the test results, it is necessary to obtain equal aliquots of the same liquid sub-samples at different depths below the liquid surface and mix them together for testing. Currently, when steel enterprises sample barreled liquid, they all use a long-handled ladle to extract sub-samples at different depths below the liquid surface. However, this sampling method only theoretically obtains liquids at different depths. In fact, when the long-handled ladle enters the liquid surface, it is immediately filled with the liquid on the liquid surface. This makes the sub-samples obtained whether the ladle mouth is facing up or down not the samples at the specified depth. Therefore, the representativeness of the samples obtained by the above sampling method is not strong, and the test results are distorted; and manually operating the long-handled ladle for sampling is time-consuming and laborious.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0023] Please refer to Figure 1 , a portable automatic liquid sampler for barrels, which is used to sample the liquid in the barrel, and includes a support rod 1, a water pump 2 and a sampling tube 3. The water pump 2 is installed at the lower end of the support rod 1, and the top end of the sampling tube 3 is connected to the water inlet of the water pump 2. In this embodiment, the sampling tube 3 is a rigid hollow tube structure. The sampling tube 3 is provided with a plurality of sampling ports 4 distributed on one side or the circumferential side of the sampling tube 3 along its axial direction. A handle 6 is connected to the upper end of the support rod 1 relative to the water pump 2, including a water outlet pipe 5 connected to the water outlet of the water pump 2, and the water outlet pipe 5 is connected to a sample container for collecting liquid samples. When the water pump 2 is started, the liquid at different depth positions will enter the sampling tube 3 through the sampling ports 4 and finally converge into the water outlet pipe 5 and be discharged into the sample container. This not only makes sampling convenient, reduces the labor intensity of manual operation, but also improves the accuracy of the sampling result.

[0024] The portable automatic liquid sampler for barrels includes a clamping and adjusting assembly 7 for fixing on the barrel wall. The clamping and adjusting assembly 7 includes a mounting plate 71, two fixing plates 72, a screw rod 73 and a clamping plate 74. One end of the mounting plate 71 is connected to the lower end of the water pump 2, and the other end extends towards one side of the water pump 2 to form an extension part. The two fixing plates 72 are oppositely arranged at the bottom of the extension part. One end of the screw rod 73 passes through one of the fixing plates 72 and is rotatably connected to the other fixing plate 72. The clamping plate 74 located between the two fixing plates 72 is screwed on the screw rod 73. In this embodiment, the mounting plate 71 and the water pump 2 can be removed and separated, making the sampler lighter and more suitable for situations with less sampling volume.

[0025] Clamping positions are respectively formed between the clamping plate 74 and the two fixing plates 72. Through the cooperation of the clamping plate 74 and one of the fixing plates 72, the clamping plate 74 and the fixing plates 72 respectively clamp the inner and outer sides of the barrel wall, thereby fixing the sampler on the barrel wall, saving the trouble of manually holding the sampler, and saving time and effort. By rotating the screw rod 73, the clamping plate 74 can be made to approach or move away from the two fixing plates 72 respectively, so as to adjust the size of the clamping position to adapt to barrel walls with different wall thicknesses.

[0026] Preferably, the clamping and adjusting assembly 7 includes a guide rod 75. The guide rod 75 is connected to the two fixing plates 72, and the upper part of the clamping plate 74 is movably sleeved on the guide rod 75. The guide rod 75 plays a role in guiding and limiting the clamping plate 74.

[0027] Please refer to Figure 1 , the portable barrel liquid automatic sampler further includes a support adjustment assembly 8, and the support adjustment assembly 8 includes a sliding sleeve 81 and a support leg 82. The support leg 82 is connected to the lower end of the sliding sleeve 81 and is used to support the entire sampler. It can also free the hands, saving time and effort, and is suitable for sampling barrels with relatively shallow liquid depth and relatively flat barrel bottoms. The sliding sleeve 81 is fixedly sleeved on the bottom end of the sampling pipe 3 away from the water pump 2.

[0028] In this embodiment, the height position of the sliding sleeve 81 on the sampling pipe 3 can be adjusted. The support adjustment assembly 8 includes a plurality of adjustment bolts 83 circumferentially distributed on the circumferential side of the sliding sleeve 81. The threaded end of each adjustment bolt 83 passes through the sliding sleeve 81 and abuts against the outer circumferential side of the sampling pipe 3. When adjusting the position of the sliding sleeve 81 on the sampling pipe 3, loosen the adjustment bolt 83 and adjust the sliding sleeve 81 to the appropriate position and then tighten the adjustment bolt 83.

[0029] A stopper 9 is detachably installed at the bottom end of the sampling pipe 3 to limit the sliding sleeve 81 from sliding out of the sampling pipe 3. When it is necessary to remove the support adjustment assembly 8, the stopper 9 can be removed from the bottom end of the sampling pipe 3. This situation is applicable to the use scenario where it has been fixed through the clamping adjustment assembly 7.

[0030] Preferably, an anti-slip pad is provided at the bottom end of the support leg 82 to prevent the support from slipping and possibly causing the sampler to tip over.

[0031] Preferably, a scale along its axial direction is provided on the outer peripheral wall of the sampling pipe 3, which can measure the depth of the sampling pipe 3 inserted into the liquid in the barrel, so as to facilitate adjusting the position of the sliding sleeve 81 on the sampling pipe 3.

[0032] In this embodiment, each of the plurality of sampling ports 4 can be respectively provided with a stop valve, and each stop valve can be selectively closed, so that the sampling port 4 only samples the liquid at a certain depth in the barrel.

[0033] The working principle of the portable automatic sampler for barreled liquid of the utility model is as follows: The length of the sampling time is determined according to the requirement of the total sample volume. When the sampling time or the sampling volume is relatively small, the clamping and adjusting component 7 can be first removed from the water pump 2, and the support and adjusting component 8 can be removed from the sampling pipe 3. Then, the sampling pipe 3 can be directly inserted into the liquid in the barrel through the handle 6 until all the sampling ports 4 are completely immersed in the liquid, and the water pump 2 is started to pump the liquid out of the barrel to the water outlet pipe 5. When the bottom of the barrel is relatively flat, the clamping and adjusting component 7 can be first removed from the water pump 2, and the supporting feet 82 can be placed flat in the barrel until all the sampling ports 4 are completely immersed in the liquid, and then the water pump 2 is started to pump the liquid out of the barrel to the water outlet pipe 5. When the bottom of the barrel is uneven, the support and adjusting component 8 can be first removed from the sampling pipe 3, and then the clamping plate 74 and the fixing plate 72 are clamped on the inner and outer sides of the barrel wall. After the position is fixed, the water pump 2 can be started to pump the liquid out of the barrel to the water outlet pipe 5.

[0034] Although the embodiments of the present utility model have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
