[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] See also Figure 1-6 The utility model provides a technical solution: a sampling device for petroleum product detection, comprising a hanging mechanism 1, a sampling tube 6 is mounted on the front end of the hanging mechanism 1 through a handle 8, a discharge valve 7 is fixedly installed at the bottom of the sampling tube 6, a detachable sealing cover 10 is installed on the top of the sampling tube 6, an oil inlet pipe 11 is installed on one side of the top of the sealing cover 10, an exhaust pipe 14 is installed on the top of the sealing cover 10 on the other side of the oil inlet pipe 11, a control valve 13 is installed on the periphery of the oil inlet pipe 11 and the exhaust pipe 14, and an exhaust fan 12 is connected to the other side of the exhaust pipe 14.

[0025] Based on the above-mentioned structural setting, the sampling device for petroleum product detection is composed of a hanging mechanism 1 and a sampling tube 6, wherein the hanging mechanism 1 is used to arrange and install the sampling tube 6, and the sampling tube 6 is used to sample and store different petroleum products. Specifically, during operation, after the sampling tube 6 is removed from the hanging mechanism 1, the device is first connected to an external petroleum storage device through an oil inlet pipe 11. After the connection, the exhaust fan 12 is started. After the exhaust fan 12 is powered on, the gas inside the sampling tube 6 is extracted using the exhaust pipe 14. After the extraction, a negative pressure is generated inside the sampling tube 6, so that the external oil can be guided to the inside of the sampling tube 6 for storage using the oil inlet pipe 11. After the extraction is completed, the inlet pipe is closed. The control valve 13 on the oil pipe 11 and the air extraction pipe 14 can prevent the oil inside the sampling pipe 6 from being discharged after being closed. The sampling pipe 6 is hung on the hanging mechanism 1. The oil inside the sampling pipe 6 can be discharged by opening the discharge valve 7, so as to facilitate the differentiated sampling and testing of different petroleum products. The sampling device for petroleum product testing can sample and store different petroleum products when in use by installing the sampling pipe 6. The oil inside the sampling pipe 6 can be discharged by opening the discharge valve 7. After discharge, it is convenient for users to sample and test different petroleum products. The hanging mechanism 1 can be used to suspend and limit the sampling pipe 6 when in use, so as to facilitate sampling and testing, thereby optimizing the use process.

[0026] Furthermore, the hanging mechanism 1 includes a hanging rod 101, an auxiliary rod 102, and a limiting rod 103. The auxiliary rod 102 is connected to the bottom of the hanging rod 101 via several fixing rods. The front end of the auxiliary rod 102 is equipped with several limiting rods 103, and the limiting rods 103 are located on both sides of the sampling tube 6. The top of the hanging rod 101 is equipped with a bump that matches the handle 8. Specifically, the hanging rod 101 can be used to suspend the sampling tube 6 at the front end of the hanging rod 101 using the handle 8. The auxiliary rod 102 and limiting rod 103 are used to additionally limit the sampling tube 6, preventing it from shaking and making it more stable.

[0027] Furthermore, side panels 2 are fixedly connected to both sides of the suspension mechanism 1, and a base 3 is fixedly mounted to the bottom of the side panels 2. The sides of the suspension rod 101 and the auxiliary rod 102 are fixedly connected to the side panels 2; specifically, the side panels 2 are mounted on both sides of the top of the base 3, and the position of the suspension mechanism 1 is defined by the side panels 2.

[0028] Furthermore, a placement platform 4 is placed on the top of the base 3, and a placement groove 5 is opened on the top of the placement platform 4 corresponding to the position of the discharge valve 7. Specifically, the placement groove 5 on the placement platform 4 can limit the position of the container containing oil to prevent the container used in the sampling process from tipping over.

[0029] Furthermore, an observation window 9 is fixedly mounted on the front end of the sampling tube 6, and explosion-proof glass is installed inside the observation window 9. Specifically, the observation window 9 allows the user to judge the capacity of the sampling tube 6 so as to facilitate sampling.

[0030] Furthermore, the bottoms of the oil inlet pipe 11 and the air extraction pipe 14 extend through the sealing cap 10 into the interior of the sampling tube 6. A connecting platform 15 is mounted on the top of the oil inlet pipe 11. The oil inlet pipe 11 extends deeper into the sampling tube 6 than the air extraction pipe 14 does. Specifically, the height difference between the air extraction pipe 14 and the oil inlet pipe 11 extending into the sampling tube 6 prevents the air extraction pipe 14 from extracting the oil introduced by the oil inlet pipe 11. The connecting platform 15 increases the contact area between the top of the oil inlet pipe 11 and the external structure, facilitating connection between the device and the external structure.
