DETAILED DESCRIPTION OF THE EMBODIMENTS

[0018] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0019] Please refer to Figures 1-5, the present utility model provides a technical solution: a sampling device for industrial boiler water quality inspection, including a sampling cylinder 1. A cylinder 7 is fixedly connected near the middle at the top of the inner cavity of the sampling cylinder 1. An activity hole is opened at the bottom of the cylinder 7. A circular block 11 is arranged near the middle inside the cylinder 7. A round rod 3 is fixedly connected to the bottom of the circular block 11. The bottom end of the round rod 3 passes through the inner ring of the activity hole and extends below the cylinder 7, and is fixedly connected with a sealing plug 2. And a circular groove matching the sealing plug 2 is opened at the bottom of the inner cavity of the sampling cylinder 1. An annular sealing ring is fixedly connected to the inner wall of the activity hole. The bottom end of the round rod 3 passes through the inner ring of the annular sealing ring. A fixed rod 6 is fixedly connected to the top of the sampling cylinder 1. A handle 5 is fixedly connected to the top of the fixed rod 6. A spring 9 is sleeved near the top of the fixed rod 6.
