[0018] like Figure 1 The device is a kind of sampling auxiliary device for sulfuric acid out of an underground tank of an acid depot, comprising a lower positioning platform 3, a spill prevention funnel 4, a ring 5, a beaker platform 6, and a cover plate 7. In the device, an iron plate 2 is provided at the sampling port of the sulfuric acid container 1, and a manhole 21 is provided at the sampling port of the iron plate 2, and the sampling port is placed in the manhole 21. The device is provided with a lower positioning platform 3 above the sampling port of the sulfuric acid container 1 at the manhole 21, so as to block the manhole 21 and expose the sampling port, and also serves as the installation and positioning of the spill prevention funnel 4. After the lower positioning platform 3 is installed, an anti-spill funnel 4 is arranged on the lower positioning platform 3 to prevent sulfuric acid from spilling on the iron plate 2 during sampling. At the same time, a circular ring 5 is arranged inside the anti-spill funnel 4, and a beaker stand 6 is arranged on one side of the circular ring 5. When sampling, the sampling beaker is placed on the beaker stand 6. Even if there is spillage, it will fall into the anti-spill funnel 4 and flow into the sulfuric acid container 1 again, thus avoiding corrosion and pollution of the iron plate 2 and the surrounding environment by sulfuric acid. Finally, a cover plate 7 is arranged on the other side of the beaker stand 6 to cover the outlet of the entire anti-spill funnel 4 after sampling is completed.

[0019] The device blocks the manhole 21 and positions the anti-spill funnel 4 by setting the lower positioning platform 3, so that the anti-spill funnel 4 can be installed stably and accurately, and then the sampling is completed in the anti-spill funnel 4 through the use of the anti-spill funnel 4, thereby protecting the sampling of sulfuric acid, so that even if sulfuric acid is spilled, it is placed in the anti-spill funnel 4 and flows into the sulfuric acid container 1, avoiding the corrosion of the safety passage and the manhole iron plate by the spilling of sulfuric acid, avoiding pollution to the surrounding environment, and also protecting the safety of personnel.

[0020] In another embodiment, in order to prevent the beaker platform 6 from being too large and affecting the sampling, the beaker platform 6 occupies one-third of the area of ​​the internal passage of the anti-spill funnel 4, and the beaker platform 6 is fixedly arranged on the ring 5. The cover plate 7 occupies two-thirds of the area of ​​the internal passage of the anti-spill funnel 4, and the cover plate 7 is arranged on the ring 5 by contact cover or transferred to the beaker platform 6 and then covered on the ring 5 to temporarily close the sampling port after sampling.

[0021] In another embodiment, the device provides a specific lower positioning platform 3 and a spill prevention funnel 4 used in conjunction therewith. Specifically, the lower positioning platform 3 includes a circular plate 31 and a positioning sleeve 32. The circular plate 31 of the device is set as a plate that matches the sampling port of the sulfuric acid container 1, with a through hole in the middle. The circular plate 31 covers the sampling port of the sulfuric acid container 1 and extends outward, preferably fastened to the iron plate 2 by screws. The positioning sleeve 32 is fixedly set on the circular plate 31, with a through hole in the middle of the positioning sleeve 32, and the spill prevention funnel 4 is set on the positioning sleeve 32. The anti-spill funnel 4 includes an upper positioning platform 41, an upper arc-shaped inner cavity 42, and a lower arc-shaped inner cavity 43; the upper positioning platform 41 is set as a boss matched with the positioning sleeve 32 and is placed on the positioning sleeve 32, the upper arc-shaped inner cavity 42 is set above the upper positioning platform 41, and the lower arc-shaped inner cavity 43 is set below the upper positioning platform 41, and the outer side of the lower arc-shaped inner cavity 43 is matched with the sampling port of the sulfuric acid container 1 and inserted into the sampling port. In this way, after being positioned by the lower positioning platform 3, the anti-spill funnel 4 can be well connected to the sampling port of the sulfuric acid container 1, and in the actual use process, the spilled sulfuric acid can be diverted to flow into the sulfuric acid container 1 again.

[0022] Optionally, the lower positioning platform 3 and the anti-spill funnel 4 used in conjunction therewith are connected by threads. Such a connection mode is more stable.

[0023] In another embodiment, a soft material is provided to seal the gap between the lower arc-shaped inner cavity 43 and the sampling port, and all components are made of strong acid-resistant materials, such as polytetrafluoroethylene, fluoroplastics, etc., to avoid corrosion to the auxiliary device.

[0024] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein.
