Description

Technical Field

[0001] The invention relates to the technical field of sampling detection, and in particular to a sampling device for detecting emulsified oil composite agents used for hydraulic supports. Background Art

[0002] Hydraulic support emulsified oil is suitable for the power transmission medium of coal mine hydraulic support, single hydraulic support, hydraulic electric furnace and other systems. It can effectively protect the hydraulic system and extend its service life.

[0003] Enterprises usually use oil tanks to store emulsified oil for hydraulic supports. According to sampling requirements, it is necessary to extract emulsified oil at different liquid levels from the tank containing the emulsified oil for sampling and testing to comprehensively judge the quality of the emulsified oil. Usually, a sampling tube is inserted into different liquid levels of the emulsified oil in the tank for multiple times according to usage requirements to achieve sampling of different liquid levels of the emulsified oil. However, the emulsified oil will show different qualities under the influence of temperature changes or internal liquid flow. The existing method of sampling at different liquid levels of the emulsified oil using multiple insertions will cause changes in the temperature of the emulsified oil each time it is inserted due to the time difference, and the insertion of the sampling tube will cause fluctuations in the emulsified oil, thereby affecting the accuracy of the data when the sampled emulsified oil is subsequently tested. On the other hand, the emulsified oil has viscosity, so a sampling tube needs to be replaced each time the emulsified oil is taken, which is not only cumbersome to operate, but the emulsified oil sample obtained cannot accurately reflect the quality of the emulsified oil at that time.

[0004] Therefore, we have made improvements to this problem and proposed a sampling device for detecting emulsified oil composite agents for hydraulic supports. Summary of the invention

[0005] The technical problem to be solved by the present invention is that: emulsions at different liquid levels cannot be sampled simultaneously, the sampling process generates disturbances in the upper and lower layers of the liquid, which affects the sampling accuracy and the operation is cumbersome.

[0010] As a further solution of the present invention, the bobbin is in the shape of a tube with upper and lower openings, and a connecting column is installed on one side of the bobbin, and the connecting column is fixedly connected to the connecting sleeve.

[0011] As a further solution of the present invention, the number of the telescopic rods is four, each of the telescopic rods is installed with no less than three sampling tubes, and the outer sides of the sampling tubes located at the same layer are connected to a connecting frame.

[0012] As a further solution of the present invention, the connecting frame includes a second telescopic frame, both ends of the second telescopic frame are connected with fixing ears, and the two fixing ears are respectively connected to two adjacent sampling tubes.

[0013] As a further solution of the present invention, the edge of the piston plate is a rubber plug, and the piston plate is slidably sleeved with the inner wall of the barrel.
