[0001] The utility model relates to the technical field of oil loading and unloading, in particular to a novel water-encountering self-interlocking device for an oil unloading truck. Background Art

[0002] During the unloading and storage of oil products, water may be present in the materials due to various reasons. Once the water-containing materials are not discovered in time and enter the storage tank, it will cause problems for the oil products in the tank and subsequent production. The existing methods can only sample and inspect the oil products before unloading, but it is impossible to detect and respond to the water-containing problems of materials caused by uneven oil products or operational factors in a timely manner. Utility Model Content

[0003] The utility model aims to provide a novel oil product unloading water self-interlocking device, which can help timely discover the problem of water in the material during the unloading process, and realize timely intervention and troubleshooting of the problem.

[0004] In order to achieve the above purpose, the utility model is implemented through the following technical solutions:

[0005] A novel self-interlocking device for oil unloading trucks encountering water comprises a buffer tank with a sealing structure, wherein a liquid inlet pipe and a liquid outlet pipe are provided on the upper part of the pipe wall of the buffer tank relative to each other, and the buffer tank is installed on a horizontally arranged pipeline through the liquid inlet pipe and the liquid outlet pipe, and a sliding rod is provided in the center of the buffer tank, and a buoyancy member is sleeved on the sliding rod and cooperates with the buoyancy member to slide along the axial direction of the buffer tank, and a mounting seat located above the buoyancy member is provided on the top of the buffer tank, and a proximity switch is provided at the bottom of the mounting seat.

[0006] A screw tube is centrally inserted into the mounting seat, the top of the screw tube protrudes from the mounting seat, the top of the slide bar is provided with an external thread, and the screw tube is threadedly connected with the top of the slide bar.

[0007] The buoyancy member is circular and has an arc chamfer on the side. The top surface of the buoyancy member has an annular response surface, and the response surface is a plane perpendicular to the axis of the buffer tank. The proximity switches are two and symmetrically installed from the bottom of the mounting seat, and the signals of the two proximity switches fall within the projection range of the response surface.

[0008] A valve is installed on the liquid inlet pipe, and the valve is connected to the proximity switch signal.

[0009] The bottom of the buffer tank is provided with a nut welded and fixed thereto, and the bottom end of the slide rod is threadedly connected to the nut.

[0010] A buffer sleeve is fixed on the bottom surface of the tank cover in line with the axis of the buffer tank. The buffer sleeve is a circular tube with an open bottom. The buffer sleeve covers the buoyancy member and the mounting seat inside. A through hole is provided on the upper part of the buffer sleeve near the liquid outlet.

[0011] The top of the buffer tank is provided with a tank opening, and the tank opening is matched with a tank cover which is sealed and detachably connected thereto.

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] The buoyancy of the fluid material entering the buffer tank can be responded by the buoyancy of the buoyant part. When the material contains water, the liquid density increases, generating greater buoyancy, and the buoyancy part rises. The buoyancy part rises close to the proximity switch, thereby reminding the unloading operation to intervene in time, stop the unloading to investigate the cause, and prevent the water-carrying material from entering the storage tank. Since this device is connected to the loading pipeline, it can realize uninterrupted data monitoring of the unloaded materials and realize density detection of all unloaded materials.

[0020] The present invention is further described below in conjunction with specific embodiments. It should be understood that these embodiments are only used to illustrate the present invention and are not used to limit the scope of the present invention. In addition, it should be understood that after reading the content taught by the present invention, those skilled in the art can make various changes or modifications to the present invention, and these equivalent forms also fall within the scope defined by the present application.

[0021] Embodiment 1:

[0022] By installing the interlocking device of this example on the loading pipeline, the problem of water in the material can be discovered in time, and the unloading can be stopped by interlocking. The main structure includes a buffer tank 1, and the upper part of the pipe wall of the buffer tank 1 is provided with a relative and coaxial liquid inlet pipe 2 and a liquid outlet pipe 3. The outer ends of the liquid inlet pipe 2 and the liquid outlet pipe 3 are respectively provided with flanges. The buffer tank 1 is installed on the horizontally arranged pipeline through the liquid inlet pipe 2 and the liquid outlet pipe 3.

[0023] The top of the buffer tank 1 is provided with a circular tank opening, which is convenient for inspection, adjustment and replacement of the internal components to ensure the effectiveness of the device. The tank opening is threadedly connected with a tank cover 4, which can be sealed with the tank opening and pressure-resistantly seal the buffer tank 1. Not limited to this example, other sealing connection structures can also be used, for example, connecting flanges can be provided on the bottom and the tank opening of the tank cover 4, and rubber washers can be provided on the contact surface, and the tank cover 4 can be fixed to the tank opening by bolts.

[0024] The bottom of the buffer tank 1 is provided with a nut 5 welded and fixed thereto, and the internal thread of the nut 5 is matched with a slide rod 6 threadedly connected thereto, and a buoyancy member 7 is sleeved on the slide rod 6 and slidably matched therewith. The buoyancy member 7 can be of any shape. In order to better resist the influence of impact, as a preference, the buoyancy member 7 is circular and has an arc chamfer on the side, which can better reduce the influence of impact through the fluid, and the top surface of the buoyancy member 7 has an annular response surface 8, which is a plane perpendicular to the axis of the buffer tank 1 and is used to correspond to the proximity switch 10 above. The annular plane serves as the response surface 8 and can float vertically up and down relative to the axis of the buffer tank 1, so that each position on the response surface 8 is equidistant from the approach and distance of the proximity switch 10 above, and based on the annular shape, the position of the proximity switch 10 and the rotation of the buoyancy member 7 do not affect the triggering effect.

[0025] The upper part of the slide bar 6 is provided with an external thread, and is matched with a mounting seat 9 threadedly connected thereto, a screw tube 11 is centrally penetrated through the mounting seat 9 and matched with the top thread of the slide bar 6, the top of the screw tube 11 protrudes from the mounting seat 9, and a straight handle 12 is provided on the top side wall of the screw tube 11, which is convenient for rotating the mounting seat 9, facilitating the installation of the mounting seat 9 on the top of the slide bar 6, or facilitating the adjustment of the height of the mounting seat 9 relative to the slide bar 6, thereby being able to adjust the corresponding range of buoyancy.

[0026] The mounting seat 9 of this example is rectangular, but is not limited to this example and may also adopt other shapes. Both sides of the mounting seat 9 are provided with mounting grooves symmetrically arranged relative to the spiral tube 11, and a proximity switch 10 is fixed in the mounting groove. The double switch ensures that the device will not malfunction.

[0027] The proximity switch 10 can be a common proximity switch 10 in the prior art. If the selected proximity switch 10 is a photoelectric proximity switch 10, it can directly sense the approach of the lower buoyancy member 7. If the selected eddy current proximity switch 10 is a metal sheet of equal size ring shape is set on the response surface 8.

[0028] It is recommended to use a wireless proximity switch 10, that is, various wireless proximity sensor products. If the selected proximity switch 10 is wired, a threading hole is provided on the tank cover 4. After the mounting seat 9 is installed, the wiring can be led out from the threading hole.

[0029] Based on the induction between the proximity switch 10 and the response surface 8 below, the height data of the buoyancy member 7 from the proximity switch 10 can be obtained. This data is continuous data monitored in real time, and there is uninterrupted data recording and feedback on the density of the oil product. When the material contains water, the liquid density increases, generating greater buoyancy, and the buoyancy member 7 rises, thereby achieving proximity to the proximity switch 10.

[0030] When it is found that the height of the buoyancy member 7 changes significantly, the unloading can be stopped manually.

[0031] At the same time, a valve can be further installed on the liquid inlet pipe 2, and the valve is linked with the proximity switch 10. At the same time, a distance threshold is set for the data obtained by the proximity switch 10. When the height of the buoyancy member 7 and the proximity switch 10 is less than a certain value, the valve is directly triggered to close, triggering the interlocking effect, interrupting the passage, and stopping the unloading.

[0032] The mounting seat 9 is height-adjustable, so that the height of the proximity switch 10 can be adjusted while adjusting the parameters, so as to adapt to materials of different densities and achieve linkage response of unloading.

[0033] Embodiment 2:

[0034] On the basis of Example 1, a buffer sleeve 13 is fixed on the bottom surface of the tank cover 4, which is axially consistent with the buffer tank 1. The buffer sleeve 13 is a round tube type, and the bottom of the buffer sleeve 13 is arranged close to the bottom of the buffer tank 1. After the tank cover 4 is closed on the buffer tank 1, the buffer sleeve 13 covers the buoyancy member 7 and the mounting seat 9 inside. The bottom of the buffer sleeve 13 is an open structure, and the upper part of the buffer sleeve 13 is provided with a long strip of through holes 14 near the liquid outlet. The through holes 14 are fan-shaped and distributed on the side of the buffer sleeve 13 near the liquid outlet, so as to promote the communication between the buffer sleeve 13 and the external liquid, and do not affect the response of the buoyancy member 7. The buffer sleeve 13 can prevent the high-pressure fluid from entering the buffer tank 1, which has a large impact on the buoyancy member 7 and affects the height of the buoyancy member 7, causing the data to fluctuate violently and affecting the data accuracy. Based on the setting of the buffer sleeve 13, the direct impact of the entering fluid on the buoyancy member 7 can be avoided.
