Description

Technical Field

[0001] The utility model relates to the technical field of water quality detection devices, in particular to a sampling device for detecting water quality in fish ponds. Background Art

[0002] Fish pond water quality testing is a key link in ensuring the healthy growth of ornamental fish. Through systematic analysis of fish pond water, potential water quality problems can be discovered and resolved in a timely manner, thereby providing a good living environment for fish. Therefore, a sampling device for fish pond water quality testing is required.

[0003] The existing sampling device for water quality detection presses the plug block so that the plug block squeezes the push spring and is stored in the socket, and then rotates the rotating rod to separate the sealing plate from the water inlet, so that the water inlet is connected to the sampling bottle, so that water at different depths in the river can enter the corresponding chamber through the corresponding water inlet. After the sampling is completed, the rotating rod is reversed, and when the socket is aligned with the water inlet, the plug block is inserted into the water inlet under the action of the push spring, so that the plug block and the sealing plate simultaneously block the water inlet, making the water quality detection of water at different depths in the river less susceptible to influence. However, after each use, this device needs to be cleaned internally to prevent it from affecting the next test result. The cylinder wall is not easy to clean, and the internal structure is complex, making it difficult to replace the internal parts after damage. The technical solution provided by the utility model with application number CN202320533315.7 also has the above-mentioned problems. Utility Model Content
