Description

Technical Field

[0001] The utility model relates to the technical field of crane pipes, in particular to an underwater loading device for a loading station. Background Art

[0002] The underwater loading device is also called the crane pipe. It is a specialized liquid cargo (mainly refers to the products after petroleum refining, such as gasoline, diesel, etc.) loading and unloading equipment. In the petrochemical production process, it is mainly used to safely unload or load liquid cargo on the vehicle. The crane pipe can swing in position during use, so it has high flexibility. In the process of loading and unloading liquid cargo, in order to ensure the quality of liquid cargo, it is necessary to randomly sample the liquid cargo for testing. At this stage, sampling work is generally carried out before loading and unloading of cargo or after loading and unloading is completed. At this stage, after the crane pipe is connected to the truck, there is no way to perform sampling operations. After the loading and unloading work is completed, the samples are collected. Since they are not completely random sampling, the collected samples are difficult to be representative, and sometimes they cannot fully reflect the quality of the liquid cargo.

[0015] In order to more clearly understand the above-mentioned purposes, features and advantages of the utility model, the utility model is further described in detail below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0016] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the protection scope of the present invention is not limited to the specific embodiments disclosed below.

[0017] like Figure 1-4 As shown, the underwater loading device of the loading station described in this embodiment includes a crane pipe inner arm 1, a swingable crane pipe outer arm 2 is horizontally placed on the top of the crane pipe inner arm 1, a vertical pipe 3 is provided at the end of the crane pipe outer arm 1 away from the crane pipe inner arm 2, a liquid outlet pipe 4 is horizontally placed at the lower end of the vertical pipe 3, an API joint 5 is provided at the end of the liquid outlet pipe 4, a sampling joint 6 is provided at the lower end of the liquid outlet pipe 4, a sampling tube 7 is provided at the sampling joint 6, and a sampling bottle 8 is provided at the liquid outlet of the sampling tube 7.

[0018] The upper end of the sampling tube 7 is threadedly connected to the sampling connector 6 . A limiting disk 9 is provided on the outer wall of the upper portion of the sampling tube 7 . A sealing ring 10 is provided between the limiting disk 9 and the port of the sampling connector 6 .

[0019] The upper end of the limiting plate 9 is provided with an annular groove at a position corresponding to the outer edge of the liquid outlet pipe 4, and the lower end of the sealing ring 10 is installed in the annular groove. The upper end of the sealing ring 10 extends out of the annular groove and its upper end is in a groove shape that is narrow at the top and wide at the bottom. The limiting plate 9 is evenly provided with serrated grooves 9a at positions along the outer periphery of the annular groove. The serrated grooves 9a are connected to the annular groove, and the sampling joint 6 is provided with an annular groove groove 6a at the inner edge of its lower end.

[0020] The sampling tube 7 is provided with a sampling valve 11 at a position corresponding to the position below the limiting plate 9 .

[0021] The bottle head of the sampling bottle 8 is threadedly connected to the sampling tube 7 .

[0022] When installing the sampling tube 7, first, the sealing ring 10 is sleeved on the upper end of the sampling tube 7, and the lower end of the sealing ring 10 is inserted into the annular groove of the limiting disk 9, and the upper end of the sealing ring 10 extends to the outside of the limiting disk 9, and then the sampling tube 8 is tightened in the sampling joint 6. As the limiting disk 9 continuously rotates toward the side of the sampling joint 6, the groove-like structure on the sealing ring 10 will enter the groove groove 6a on the sampling joint 6, and the edge of the sampling joint 6 cooperates with the limiting disk 9 to squeeze the sealing ring 10. The squeezed sealing ring 10 will be deformed. At this time, the upper end of the sealing ring 10 is deformed and filled in the groove groove 6a, and the middle part of the sealing ring 10 is also deformed and filled into each toothed groove 9a. Such an arrangement can greatly improve the sealing performance of the sealing ring 10, thereby preventing leakage of liquid cargo.

[0023] The inner wall 1 of the crane tube is connected to the outer arm 2 of the crane tube through a deflection tube (not shown in the figure). A spring cylinder 12 is provided on the outer arm 2 of the crane tube. A rotating part 13 is provided on the deflection tube. The piston rod of the spring cylinder 12 is connected to the rotating part 13.

[0024] The working principle of the utility model is as follows: the tank truck is parked at one side of the crane pipe, and then the entire crane pipe device is swung to connect the API joint on it with the liquid inlet on the tank truck, and the valve on the API joint 5 is opened, so that liquid goods can be poured into the oil tank of the tank truck, or the liquid goods can be transported from the tank body of the tank truck to the liquid storage tank. During the loading and unloading process, the staff can collect samples by opening the sampling valve 11 on the sampling tube 7. The collected samples are collected by the sampling bottle 8 and then sent to inspect the quality of the oil sample.

[0025] The embodiments of the present invention are provided for the purpose of illustration and description, and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations will be apparent to those of ordinary skill in the art.
