Description

Technical Field

[0001] This utility model relates to the field of storage tank technology, and in particular to a manhole-fixed storage tank cleaning device. Background Technology

[0002] Crude oil is a complex mixture of multiple components, its base being paraffinic hydrocarbons, cycloalkanes, and aromatic hydrocarbons, along with non-hydrocarbon resins and asphaltenes. During prolonged storage in tanks, the heavier components in the crude oil undergo changes in saturation levels due to the combined effects of gravity, temperature, and pressure. This ultimately leads to the formation of sediment at the bottom of the tank, reducing storage space and lowering oil quality. Therefore, crude oil storage tanks require regular inspection, maintenance, and cleaning of the sediment. Timely and effective tank cleaning is essential to maintain high-efficiency production.

[0003] However, existing cleaning methods generally fall into two categories: manual cleaning inside the tank and cleaning with high-pressure water jets outside the tank. Both methods require skilled workers to maintain high-intensity work for extended periods, resulting in very high labor intensity for the workers and hindering the cleaning of the storage tanks. Utility Model Content

[0017] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0018] Reference Figures 1 to 3 According to an embodiment of the present invention, the manhole-fixed storage tank cleaning device includes a mounting base 10, a mounting frame 20, and a high-pressure water gun 30. The mounting base 10 is mounted on the manhole of the storage tank (not shown in the figure); the mounting frame 20 is swayably mounted on the mounting base 10 and is used to mount the high-pressure water gun 30; the high-pressure water gun 30 is swayably mounted on the mounting frame 20, and the swaying direction of the mounting frame 20 is perpendicular to the swaying direction of the high-pressure water gun 30.

[0019] Specifically, the manhole-fixed tank cleaning device of this embodiment mainly consists of three parts: a mounting base 10, a mounting frame 20, and a high-pressure water gun 30. The mounting base 10 is the basic fixing component of the entire device. It is made of high-strength alloy steel, possessing good strength and corrosion resistance, and can adapt to the complex working environment of crude oil storage tanks. The mounting base 10 is designed as a strip structure or a ring structure that matches the manhole of the storage tank. During installation, the mounting base 10 is aligned with the manhole of the storage tank, and the mounting base 10 is firmly fixed to the edge of the manhole using bolts, ensuring that the mounting base 10 will not shake or shift during the cleaning process. The mounting frame 20 is swayably mounted on the mounting base 10. Its main body is a rectangular frame 21 structure, also made of high-strength alloy steel. The mounting frame 20 and the mounting base 10 are connected by a rotatable connecting shaft. This connecting shaft uses high-precision bearings, allowing the mounting frame 20 to swing freely in the horizontal direction around the connecting shaft. The swing range of the mounting bracket 20 can be designed according to actual cleaning needs, generally swinging within ±80° to meet the cleaning requirements of different lateral areas within the storage tank. The high-pressure water gun 30 is swingably mounted on the mounting bracket 20, and its body is connected to the mounting bracket 20 via a universal ball joint connector. The universal ball joint connector has multiple degrees of freedom, allowing the high-pressure water gun 30 to swing freely in the vertical direction. Its swing range can also be set according to actual needs, typically within ±80°. Since the swing direction of the mounting bracket 20 is horizontal and the swing direction of the high-pressure water gun 30 is vertical, they are perpendicular to each other, thus achieving the multi-directional spraying function of the high-pressure water gun 30.

[0020] In practical use, technicians first fix the mounting base 10 to the manhole of the storage tank, and then install the high-pressure water gun 30 on the mounting frame 20. By controlling the horizontal swing of the mounting frame 20 and the vertical swing of the high-pressure water gun 30, technicians can easily adjust the spray direction of the high-pressure water gun 30 through the water pipe, aiming it at the parts of the storage tank that need cleaning. After turning on the high-pressure water gun 30, the high-pressure water flow can powerfully impact and flush the sediment in the storage tank, peeling and washing away the sediment from the tank wall and bottom. Since technicians only need to operate the high-pressure water gun 30 through the water pipe at the manhole, without having to enter the tank or perform high-intensity operations outside the tank for extended periods, the labor intensity is greatly reduced. At the same time, the omnidirectional spray function of the high-pressure water gun 30 also makes the cleaning more comprehensive and thorough, effectively improving the cleaning efficiency of the storage tank.

[0021] Therefore, it is understood that the manhole-fixed tank cleaning device according to the embodiments of this utility model has at least the following beneficial effects: The manhole-fixed tank cleaning device provided by this utility model is fixed on the manhole of the tank by the mounting base 10. The mounting frame 20 is swayably mounted on the mounting base 10, and the high-pressure water gun 30 is swayably mounted on the mounting frame 20. The swaying direction of the mounting frame 20 is perpendicular to the swaying direction of the high-pressure water gun 30. This structure allows the high-pressure water gun 30 to have multiple spray directions. Technicians only need to operate the high-pressure water gun 30 at the manhole, without having to maintain high-intensity work for a long time, which greatly reduces labor intensity and is also conducive to the cleaning of the tank, improving cleaning efficiency.

[0022] Reference Figures 1 to 3 In some embodiments of this utility model, a first roller 11 is provided on the mounting base 10, and the mounting frame 20 includes a frame 21 and two first rotating shafts 22. One end of the two first rotating shafts 22 is disposed opposite to each other on the frame 21, and the axes of the two first rotating shafts 22 coincide with each other. Both first rotating shafts 22 can be inserted into the first roller 11, and the frame 21 can rotate about the axes of the first rotating shafts 22.

[0023] Specifically, in this embodiment, a first roller 11 is specially provided on the mounting base 10. The first roller 11 is made of a high-strength metal material, such as stainless steel, to ensure sufficient strength and wear resistance to withstand the friction and force generated when the mounting frame 20 rotates. The first roller 11 is securely mounted on the mounting base 10 by welding or bolting, and its position is in the central area of ​​the mounting base 10, providing a stable support point for the rotation of the mounting frame 20. The mounting frame 20 is specifically composed of a frame 21 and two first rotating shafts 22. The frame 21 is also made of high-strength alloy steel and is rectangular in shape. This structure ensures the strength of the mounting frame 20 and facilitates the installation of other components such as the high-pressure water gun 30. One end of each of the two first rotating shafts 22 is positioned opposite each other on corresponding positions on both sides of the frame 21, and the axes of the two first rotating shafts 22 coincide, ensuring that the mounting frame 20 can rotate smoothly around the axis. The diameter of the first rotating shaft 22 is precisely designed according to the inner diameter of the first roller 11, so that both first rotating shafts 22 can be smoothly inserted into the first roller 11, and there is an appropriate gap between them, which ensures flexible rotation and prevents shaking due to excessive gap.

[0024] In the actual installation process, the mounting base 10 is first fixed to the manhole of the storage tank to ensure its stability and reliability. Then, the two first rotating shafts 22 of the mounting frame 20 are aligned with the first roller 11, and the first rotating shafts 22 are inserted into the first roller 11 to complete the connection between the mounting frame 20 and the mounting base 10. At this time, the frame 21 can rotate freely around the axis of the first rotating shaft 22. When cleaning the storage tank, technicians can operate the frame 21 to rotate it horizontally around the axis of the first rotating shaft 22, thereby changing the horizontal spray angle of the high-pressure water gun 30 mounted on the frame 21. Combined with the swing function of the high-pressure water gun 30 in the direction perpendicular to the swing direction of the frame 21, the spray flexibility of the high-pressure water gun 30 is further enhanced, enabling more comprehensive and efficient cleaning of different locations inside the storage tank, effectively improving cleaning efficiency and reducing the labor intensity of workers.

[0025] Reference Figures 1 to 3 In some embodiments of this utility model, a second roller 23 is provided on the frame 21, and two second rollers 23 are provided. The axes of the two second rollers 23 coincide with each other, and the axes of the second rollers 23 are perpendicular to the axes of the first roller 11. A second rotating shaft 32 is provided on the periphery of the high-pressure water gun 30, and the second rotating shaft 32 can be inserted into the second roller 23.

[0026] Specifically, in this embodiment, two second rollers 23 are further provided on the frame 21. These two second rollers 23 are also made of high-strength, wear-resistant metal materials, such as alloy steel, to ensure they can withstand the various forces generated by the rotation of the high-pressure water gun 30 during long-term use and are not easily damaged. The two second rollers 23 are precisely installed on the frame 21, their axes coincidentally, and this axis is perpendicular to the axis of the first roller 11. This perpendicular axis layout design allows the high-pressure water gun 30 to rotate flexibly in different directions. During installation, the installation positions of the two second rollers 23 are first determined on the frame 21, and the second rollers 23 are firmly installed on the frame 21 by welding or bolting to ensure installation accuracy and avoid axial misalignment that could affect subsequent use. A second rotating shaft 32 is specially provided on the periphery of the high-pressure water gun 30. The diameter of the second rotating shaft 32 is adapted to the inner diameter of the second roller 23 to ensure that the second rotating shaft 32 can be smoothly inserted into the second roller 23. When installing the high-pressure water gun 30, align the second rotating shaft 32 on the high-pressure water gun 30 with the second roller 23 on the frame 21, and slowly insert the second rotating shaft 32 into the second roller 23 to complete the connection between the high-pressure water gun 30 and the frame 21.

[0027] During actual cleaning operations, the mounting frame 20 can rotate horizontally around the axis of the first rotating shaft 22 (i.e., the axis of the first roller 11), while the high-pressure water gun 30 can rotate vertically around the axis of the second rotating shaft 32 (i.e., the axis of the second roller 23). These two rotations are independent yet coordinated. Technicians can easily adjust the spray direction of the high-pressure water gun 30 by operating it through the manhole of the tank, ensuring comprehensive and thorough cleaning of all parts of the tank. This design not only significantly reduces the labor intensity of workers, avoiding them having to enter the tank or perform high-intensity operations outside for extended periods, but also significantly improves the cleaning efficiency of the tank, ensuring a more thorough cleaning effect.

[0028] Reference Figures 1 to 3 In some embodiments of this utility model, the high-pressure water gun 30 is mounted in the mounting frame 20 through the mounting sleeve 31, and the high-pressure water gun 30 is detachably mounted in the mounting sleeve 31 through the mounting sleeve 31. The second rotating shaft 32 is mounted on the mounting sleeve 31.

[0029] Specifically, in this embodiment, the high-pressure water gun 30 is mounted in the mounting frame 20 via a specially designed mounting sleeve 31. The mounting sleeve 31 is made of a high-strength engineering plastic material with a certain degree of toughness, such as polyamide (PA). This material not only has high strength, capable of withstanding the vibration and impact forces during the operation of the high-pressure water gun 30, but also has good wear resistance and corrosion resistance, making it suitable for the complex working environment inside crude oil storage tanks. The mounting sleeve 31 is designed as a cylindrical structure that matches the outer contour of the high-pressure water gun 30, with its inner diameter slightly larger than the outer diameter of the high-pressure water gun 30, ensuring that the high-pressure water gun 30 can be smoothly inserted into the mounting sleeve 31. An elastic rubber pad is provided on the inner wall of the mounting sleeve 31, with anti-slip textures on its surface. When the high-pressure water gun 30 is inserted into the mounting sleeve 31, the rubber pad can tightly adhere to the surface of the high-pressure water gun 30, providing fixation and cushioning to prevent damage to the high-pressure water gun 30 due to shaking during operation, while also reducing noise. The high-pressure water gun 30 is detachably installed in the mounting sleeve 31. Specifically, a threaded hole is provided on the side wall of the mounting sleeve 31, and a matching locking bolt is provided. After inserting the high-pressure water gun 30 into the mounting sleeve 31 to the appropriate position, the locking bolt is tightened, so that the end of the bolt firmly abuts against the high-pressure water gun 30, thereby achieving a secure connection between the high-pressure water gun 30 and the mounting sleeve 31. When it is necessary to disassemble the high-pressure water gun 30 for maintenance or replacement, simply loosen the locking bolt to easily remove the high-pressure water gun 30 from the mounting sleeve 31; the operation is convenient and quick. A second rotating shaft 32 is disposed on the mounting sleeve 31. Specifically, a short shaft is welded to each of the opposite outer walls of the mounting sleeve 31 as the second rotating shaft 32. The axes of these two second rotating shafts 32 coincide and are adapted to the axis of the second roller 23 described in claim 3. When installing the mounting sleeve 31 with the high-pressure water gun 30 onto the mounting frame 20, align the second rotating shaft 32 on the mounting sleeve 31 with the second roller 23 on the frame 21, and slowly insert the second rotating shaft 32 into the second roller 23 to complete the connection between the mounting sleeve 31 and the frame 21.

[0030] In practical use, this design makes the installation and disassembly of the high-pressure water gun 30 very convenient, facilitating regular maintenance, repair, or replacement with different specifications to meet various cleaning needs. Simultaneously, connecting the high-pressure water gun 30 to the mounting bracket 20 via the mounting sleeve 31 further enhances the stability and reliability of the entire device, ensuring stable operation of the high-pressure water gun 30 during cleaning and improving the cleaning efficiency and quality of the storage tank.

[0031] Reference Figures 1 to 3In some embodiments of this utility model, two mounting seats 10 are provided, spaced apart, and detachably mounted on the manhole of the storage tank. Specifically, in this embodiment, the manhole-fixed storage tank cleaning device is provided with two mounting seats 10, which are arranged at intervals. The mounting seats 10 are made of high-strength alloy steel, and their surfaces undergo special anti-corrosion treatment, such as galvanizing or spraying with anti-rust paint, to adapt to the complex and corrosive working environment inside the crude oil storage tank, ensuring that the mounting seats 10 will not be damaged by corrosion during long-term use, thus guaranteeing the stability and reliability of the device. Each mounting seat 10 is designed to match the shape of the edge of the storage tank manhole, generally a long strip plate structure. The two mounting seats 10 are detachably mounted on the manhole of the storage tank. The specific installation method is as follows: First, according to the actual size and position of the storage tank manhole, the installation interval distance of the two mounting seats 10 is determined to ensure that the mounting frame 20 can be stably mounted on the two mounting seats 10. Then, the two mounting bases 10 are placed at corresponding positions on the edge of the manhole, and fixed to the edge of the manhole by bolts. Each mounting base 10 has multiple bolt holes; bolts pass through these holes and are tightened onto the fixing plate on the edge of the manhole, ensuring a secure installation of the mounting base 10. Furthermore, standard bolts are used for easy disassembly and installation, facilitating replacement and operation.

[0032] When maintenance, repair, or replacement of parts is required for the cleaning device, simply loosening the bolts allows for the removal of the two mounting seats 10 from the manhole, making the operation convenient and quick. This design of two spaced-apart, detachable mounting seats 10 not only enhances the installation stability of the entire cleaning device, better withstanding the various forces generated by the mounting frame 20 and the high-pressure water gun 30 during operation, but also facilitates the installation, disassembly, and transportation of the device, improving its practicality and flexibility. This makes it suitable for installation and use on different storage tanks, meeting diverse cleaning needs.

[0033] Reference Figures 1 to 3 In some embodiments of this utility model, the mounting base 10 is provided with an oblong mounting hole, and the mounting base 10 is installed at the manhole of the storage tank through the mounting hole.

[0034] In this embodiment, the mounting base 10 of the manhole-fixed tank cleaning device is specially provided with waist-shaped mounting holes. These waist-shaped mounting holes are formed on the mounting base 10 by a stamping process, and the edges of the holes are finely ground to ensure a smooth, burr-free surface, preventing scratches to operators or damage to the manhole edge during installation. The mounting base 10 is made of high-strength stainless steel with a certain degree of toughness to adapt to the complex working environment inside the tank and resist potential corrosion and mechanical stress. The distribution of the waist-shaped mounting holes on the mounting base 10 is carefully designed. Based on the overall structure and stress conditions of the mounting base 10, at least two waist-shaped mounting holes are usually provided on each mounting base 10, and the two waist-shaped mounting holes are symmetrically distributed at both ends of the mounting base 10. When installing the mounting base 10 at the manhole of the tank, the special shape of the waist-shaped mounting holes provides greater adjustment space for installation. The specific installation process is as follows: First, the mounting base 10 is roughly placed at the predetermined position on the edge of the manhole; at this time, precise alignment of the bolt holes is not required. Then, using bolts passed through the oblong mounting hole and the corresponding fixing hole at the edge of the manhole (if there is no fixing hole at the edge of the manhole, a fixing plate can be welded and drilled in advance), after initially tightening the bolts but not completely locking them, the position of the mounting base 10 can be finely adjusted along the length of the oblong mounting hole according to the actual installation conditions, such as the flatness of the mounting base 10 and its fit with the manhole. This fine-tuning function allows the mounting base 10 to better adapt to manholes of different specifications and sizes, as well as situations such as uneven manhole edges, ensuring that the mounting base 10 can be installed securely and accurately at the manhole.

[0035] After adjusting the mounting base 10 to its optimal position, fully tighten the bolts to securely fix the mounting base 10 to the edge of the manhole. When disassembly or reinstallation of the cleaning device is required, the oblong mounting hole facilitates operation; simply loosen the bolts to move the mounting base 10 to a certain extent, making it easy to remove from the manhole or readjust and reinstall. This oblong mounting hole design greatly improves the installation flexibility and versatility of the mounting base 10, enhancing the practicality and reliability of the entire cleaning device.

[0036] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0037] Of course, this utility model is not limited to the above-described embodiments.

All such equivalent modifications or substitutions are included within the scope defined by the claims of this application.
