This utility model relates to the field of transformer testing technology, specifically disclosing a transformer insulating oil sampling device, including a shell. The shell is a hollow cuboid structure, and an outer cylinder is fixedly connected to the inner wall of the shell via a connecting rod. The outer cylinder is a hollow cylindrical structure, and an oil inlet pipe, a sampling pipe, an oil outlet pipe, and a sampling tube are respectively installed through the outer surface of the outer cylinder. This transformer insulating oil sampling device features a rotatably connected outer cylinder and inner cylinder. The inner cylinder has a three-way flow channel, and the flow channel between the pipes can be adjusted by rotating the inner cylinder. This allows the pipes inside the device to be flushed before sampling, removing residual air impurities and other substances that interfere with the experiment, improving the accuracy of insulating oil sampling, and making subsequent test data more accurate and reliable.

The utility model relates to a fixed circulating pool sampling device, including sampling pump, main pipeline, pool insertion pipe and connecting pipe, one end of main pipeline is detachably connected with one end of connecting pipe and communicates, and the other end of connecting pipe communicates with the inlet of sampling pump, one end of pool insertion pipe is detachably connected with the other end of main pipeline and communicates, and the other end is used for inserting into sampling pool, the vent line is communicated on main pipeline, and the vent valve is fixedly installed on the vent line. The utility model has the advantages of simple structure, reasonable design, can realize the quick automatic sampling of circulating pool, is convenient for sampling, does not need artificial to lie on the edge of circulating pool and sample, and is simple and safe and reliable to operate.

The utility model provides a kind of intelligent vibration sampler suitable for complex sea conditions of middle and shallow sea, it is related to sampling device technical field, to solve the problem that the existing vibration sampler cannot detect seabed condition in the process of sampler lowering when using due to complex seabed condition, it includes: base;The inside of the base is equipped with middle connector block;The camera is fixedly connected on the outer wall of the middle connector block of the base;Pressure sensor is fixedly connected on the outer wall of the middle connector block of the base;Attitude instrument is fixedly connected on the outer wall of the middle connector block of the base.External control terminal is connected with portable cable through junction box, can receive seabed environment image photographed by camera, pressure data detected by pressure sensor and attitude information fed back by attitude instrument in real time, and operator can intuitively understand the working condition of sampler under water and surrounding environment in safe position away from sampling site through external control terminal.
