Description

Technical Field

[0001] The utility model belongs to the technical field of liquid hydrocarbon sampling tools, in particular to a liquid hydrocarbon tank truck sampling tool. Background Art

[0002] Liquid hydrocarbons refer to hydrocarbon compounds with 5 to 16 carbon atoms that are liquid at room temperature and pressure. Liquid hydrocarbons generally refer to hydrocarbons that are liquid at room temperature and pressure. During the transportation of liquid hydrocarbons by tank trucks, sampling tools are required to sample and test the liquid hydrocarbons inside the tank trucks. Existing sampling tools have low sampling efficiency for liquid hydrocarbons.

[0003] When existing sampling tools are used to sample liquid hydrocarbons inside a tank truck, liquid hydrocarbons will adhere to the surface of the sampling tool. To prevent the waste of liquid hydrocarbon resources, the sampling tool needs to be suspended to achieve a drainage effect on the sampling tool, thereby allowing the liquid hydrocarbons adhering to the surface of the sampling tool to naturally fall and flow into the tank truck. This takes a long time and reduces the sampling efficiency of the sampling tool for liquid hydrocarbons. Utility Model Content

DETAILED DESCRIPTION

[0023] In the following description, numerous specific details are provided to provide a more thorough understanding of the present invention. However, it will be apparent to those skilled in the art that the present invention can be practiced without one or more of these details. In other instances, certain technical features known in the art are not described to avoid confusion with the present invention.

[0024] Unless otherwise defined, the directions of up, down, left, right, front, back, inside and outside involved in this document are based on the directions of up, down, left, right, front, back, inside and outside shown in the figures of the present invention, and are explained here together.

[0025] The connection method can be bonding, welding, bolt connection, etc., which shall be based on actual needs.

[0026] In order to solve the problem of low sampling efficiency of liquid hydrocarbons when using the sampling tool of liquid hydrocarbon tank truck, please refer to Figures 1 to 4The structure of the device body is as follows: the sampling rod 1 is hollow inside, and two L-shaped fixing plates 3 are welded on the outer wall of the sampling rod 1. The adjacent sides of the two fixing plates 3 are welded to the sampling rod 1 to fix the positions of the two fixing plates 3. The inner wall of the fixing plate 3 is welded with a sliding rod 4, and the end face of the sliding rod 4 is welded with a connecting plate 5. The provided connecting plate 5 and the fixing plate 3 fix the position of the sliding rod 4. The adjacent sides of the two connecting plates 5 are fixedly connected with the hollow connecting rod 2 inside. The outer wall of the connecting rod 2 is sleeved with a scraper ring 7, and the inner wall of the scraper ring 7 is in sliding friction contact with the connecting rod 2, so that the scraper ring 7 can scrape off the liquid hydrocarbons adhered to the surface of the connecting rod 2 during movement, thereby preventing the sampling tool from wasting liquid hydrocarbon resources when sampling and detecting liquid hydrocarbons, and shortening the hanging and draining time of the sampling tool, thereby improving the sampling efficiency of the sampling tool for liquid hydrocarbons. The outer wall of the scraper ring 7 is fixedly connected with two sliders 6.

[0027] The two sliders 6 are adjacent to the scraper ring 7 and are fixedly connected to the position of the two sliders 6. The side of the slider 6 is slidably connected to the slide bar 4 through the through groove opened. The slide bar 4 is fixed to the moving path of the slider 6, thereby improving the moving stability of the scraper ring 7. The side of the connecting plate 5 is embedded with an iron fixing rod 8 and fixedly connected, and the end face of the fixing rod 8 passes through the connecting plate 5. The side of the fixing rod 8 is plugged with a plug-in rod 9 through the groove opened, so that the plug-in rod 9 extends into the inner cavity of the fixing rod 8. The end face of the plug-in rod 9 is fixedly connected with a magnetic block 10. The side of the magnetic block 10 is magnetically connected to the fixing rod 8 through the magnetic block 10 and the fixing rod 8. The storage and fixing of the scraper ring 7 is achieved during the transmission process. At the same time, the side of the plug-in rod 9 is plugged into the fixing rod 8 to prevent the side of the magnetic block 10 from shaking and deviating from the magnetic connection between the fixing rod 8 and the fixing rod 8. The position fixing stability of the scraper ring 7 is strengthened during the transmission process. The plug-in rod 9 is fixedly connected to the slider 6 on the side away from the magnetic block 10.

[0028] The end face of the sampling rod 1 is connected to a sampling tube 11, which is convenient for extracting liquid hydrocarbons inside the tank truck through the sampling tube 11, so that the liquid hydrocarbons flow into the inner cavity of the sampling rod 1, thereby realizing sampling and detection of the liquid hydrocarbons transported by the tank truck. A rubber plate 12 is slidably connected to the inner wall of the sampling rod 1. The provided rubber plate 12 provides a sealing effect and facilitates the movement of the rubber plate 12. Under the action of air pressure, the liquid hydrocarbons extracted by the sampling tube 11 flow into the inner cavity of the sampling rod 1. A support plate 13 is fixedly connected to the side of the rubber plate 12. The support plate 13 provides support for the rubber plate 12, thereby enhancing the sealing effect of the rubber plate 12. The outer ring of the limit bearing 14 is embedded and fixedly connected to the side of the support plate 13. The inner ring of the limit bearing 14 is interference fit with a movable rod 15. The provided limit bearing 14 fixes the rotation position of the movable rod 15 and facilitates the relative rotation of the movable rod 15 and the support plate 13.

[0029] The end face of the movable rod 15 is welded with a shielding plate 16, and the adjacent sides of the two shielding plates 16 are fixedly connected with a threaded rod 17, and the threaded rod 17 is threadedly connected with a threaded sleeve 18, so that the threaded rod 17 can be rotated to move along the thread path of the threaded sleeve 18. During the transmission process, it is easy to drive the rubber plate 12 to move, so that the liquid hydrocarbon flows into the inner cavity of the sampling rod 1 through the sampling tube 11, thereby realizing the sampling of the liquid hydrocarbon. At the same time, the shielding plate 16 is provided to provide a shielding effect to prevent the threaded rod 17 from being separated from the threaded sleeve 18 during the movement, thereby improving the sampling tool. The structural stability of the components is ensured. The side of the threaded sleeve 18 is welded to the inner wall of the connecting rod 2. A movable rod 19 is welded to the side of the other baffle plate 16 away from the threaded rod 17. The end face of the movable rod 19 extends out of the connecting rod 2. A handle 20 is welded to the side of the movable rod 19 away from the baffle plate 16. The side of the sampling rod 1 away from the sampling tube 11 is welded to the connecting rod 2. The sealing blockage provided by the rubber plate 12 and the action of air pressure prevent liquid hydrocarbons from flowing into the sampling tube 11, thereby facilitating the sampling and detection of liquid hydrocarbons stored in the tank truck at a specified depth, thereby improving the sampling accuracy of the sampling tool for liquid hydrocarbons.

[0030] The working principle, size and model are irrelevant to the function of this application, so they are not described in detail. The control method of the present invention is controlled by a controller, and the control circuit of the controller can be implemented by simple programming by technicians in this field. The provision of power is also common knowledge in this field, and the present invention is mainly used to protect mechanical devices, so the present invention will no longer explain the control method and circuit connection in detail.

[0031] How it works

[0032] When using the liquid hydrocarbon tank truck sampling tool, a user extends the sampling tool into the liquid hydrocarbon stored in the tank truck to a specified depth. By controlling the sampling depth of the liquid hydrocarbon by the sampling tool, the sampling accuracy of the liquid hydrocarbon is improved. By rotating the handle 20, the threaded rod 17 is moved along the threaded path of the threaded sleeve 18 under the connection provided by the movable rod 19. The support plate 13 is driven by the rubber plate 12 to move in the direction opposite to the sampling tube 11 under the connection provided by the movable rod 15. Liquid hydrocarbon at a specified depth is introduced into the inner cavity of the sampling rod 1 through the sampling tube 11 under the action of air pressure, thereby achieving the sampling of liquid hydrocarbons and further improving the sampling accuracy of the sampling tool for liquid hydrocarbons.

[0033] The two baffles 16 are set to prevent the threaded rod 17 from separating from the threaded sleeve 18 when moving along the threaded path of the threaded sleeve 18, thereby improving the structural stability of the sampling tool components. After the sampling tool completes extracting liquid hydrocarbons, the sampling tool is separated from the liquid hydrocarbons, and the magnetic connection between the magnetic block 10 and the fixed rod 8 is released, so that the scraper ring 7 moves along the path of the connecting rod 2 to scrape off the liquid hydrocarbons adhering to the surface of the connecting rod 2, thereby improving the cleaning efficiency of the liquid hydrocarbons, and thus facilitating the improvement of the sampling efficiency of the sampling tool for liquid hydrocarbons. The set slider 6 moves along the path of the slide rod 4 to improve the movement stability of the scraper ring 7. The set fixing plate 3 and connecting plate 5 provide a position fixing function for the slide rod 4, and at the same time, the plug-in rod 9 drives the magnetic block 10 to extend into the inner cavity of the fixed rod 8, so that the magnetic block 10 is magnetically connected to the fixed rod 8, thereby providing a position fixing and storage function for the scraper ring 7.
