Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of oil tank cleaning equipment, and in particular to a high-pressure cleaning mechanism for an oil tank cleaning robot. Background Technology
[0002] Oil tanks are specialized containers used in the petrochemical, energy storage, and transportation sectors to store various types of oil products (such as crude oil, gasoline, diesel, and lubricating oil). As transit or long-term storage equipment for oil products, they prevent oil from evaporating, leaking, or deteriorating. The tank body must be completely sealed to prevent oil from evaporating or external impurities from entering. Its core function is to safely, efficiently, and for a long time preserve oil products and meet the process requirements of heating, dehydration, metering, and continuous oil supply.
[0003] Traditional high-pressure cleaning mechanisms used in oil tank cleaning robots mainly consist of a drive assembly, a high-pressure pump system, high-pressure nozzles, and a filtration device. The drive assembly carries the cleaning mechanism into the oil tank and moves it. The high-pressure pump system serves as the power source, pressurizing ordinary water to form a high-pressure water jet. The high-pressure nozzles accelerate the water flow by reducing the flow area, forming fan-shaped, cone-shaped, or rotating jets to cover different cleaning scenarios. The filtration device removes impurities from the water and prevents the high-pressure nozzles from clogging. Its working principle is based on the water jet impact principle. The high-pressure pump converts the pressure energy of the water into kinetic energy, causing the water to be sprayed out at extremely high speeds (up to 300 m / s). When the impact force of the water jet is greater than the adhesion between the dirt and the inner wall of the oil tank, the dirt is peeled off and washed away with the water flow. By adjusting the nozzle shape, pressure parameters, and spray gun movement trajectory, targeted cleaning can be achieved.
[0004] However, traditional oil tank cleaning methods rely on fixed high-pressure water jet devices, which have many problems during use. For example, traditional high-pressure nozzles are fixed and the water flow direction is unidirectional, making it difficult to meet the cleaning needs of oil tanks of different sizes, resulting in unsatisfactory cleaning results.
[0005] Therefore, this utility model proposes a high-pressure cleaning mechanism for an oil tank cleaning robot to solve the above problems. Utility Model Content

A mounting groove is formed on the outer surface of the mounting shell. A bearing is fixedly connected to the inner wall of the mounting groove. A rotating tube is fixedly connected to the inner ring of the bearing.

[0020] The technical solutions in the embodiments of this utility model will be clearly and completely described below. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0021] Please see Figures 1 to 4 This utility model provides a technical solution: a high-pressure cleaning mechanism for an oil tank cleaning robot, including a mounting shell 1 and a mounting cover plate 6. A set of fixing plates 2 are fixedly connected to both sides of the mounting shell 1, with two fixing plates 2 in each set. A fixing through hole is provided on the upper surface of each fixing plate 2, allowing the mounting shell 1 to be securely mounted on the drive assembly of the oil tank cleaning robot. A mounting groove 9 is provided on the outer surface of the mounting shell 1, and a bearing 10 is fixedly connected to the inner wall of the mounting groove 9. The bearing 10 assists in the rotation of a rotating tube 16. The inner ring of the bearing 10 is fixedly connected to the rotating tube 16, and the end of the rotating tube 16 furthest from the bearing 10 is connected to a water outlet pipe 4. A high-pressure nozzle 5 is connected to one end of the rotating tube 16. The high-pressure nozzle 5 can spray high-pressure water to clean the inner wall of the oil tank. A mounting base 11 is fixedly connected to the bottom of the inner cavity of the mounting shell 1. A rotary joint 13 is fixedly connected to the upper surface of the mounting base 11. The side of the rotary joint 13 near the bearing 10 is connected to the end of the rotating tube 16 away from the water outlet pipe 4. The rotary joint 13 can ensure the smooth flow of water in the rotating tube 16 during rotation. A bevel gear 15 is fixedly connected to the outer wall of the rotating tube 16. A limit ring 14 is fixedly connected to the outer wall of the rotating tube 16. The limit ring 14 prevents the axial displacement of the rotating tube 16, reduces wear, and extends service life. A drive shaft 18 is rotatably connected to the inner wall of the mounting shell 1.
[0022] In actual use, the mounting housing 1 is securely installed on the oil tank cleaning robot drive assembly through the fixing through hole on the fixing plate 2 to ensure a firm and reliable installation. The water inlet pipe 7 is connected to the external booster pump and water source through the flange 8 to ensure unobstructed water flow. When the external booster pump is started, the water source enters the rotating pipe 16 through the water inlet pipe 7 and the rotary joint 13, and is delivered to the water outlet pipe 4 and the high-pressure nozzle 5. The high-pressure nozzle 5 sprays out high-pressure water flow, forming a fan-shaped or cone-shaped water jet to impact the dirt on the inner wall of the oil tank.
[0023] A drive motor 3 is fixedly connected to the outer surface of the housing 1. The output end of the drive motor 3 is fixedly connected to one end of the drive shaft 18. A bevel gear 17 is fixedly connected to the end of the drive shaft 18 away from the drive motor 3. The teeth of the bevel gear 17 mesh with the teeth of the bevel gear 15. The drive motor 3 drives the bevel gear 17 to rotate, which in turn drives the bevel gear 15 and the rotating tube 16 to rotate. A water inlet pipe 7 is connected to the side of the rotary joint 13 away from the rotating tube 16. A flange 8 is fixedly connected to the end of the water inlet pipe 7 away from the rotary joint 13. Water pipe 7 is connected to an external booster pump and water source via flange 8 to ensure unobstructed water flow; two sets of threaded connecting plates 12 are fixedly connected to the inner wall of the housing 1. The two sets of threaded connecting plates 12 are symmetrically arranged, and there are two threaded connecting plates 12 in each set. Multiple through slots are opened through the outer surface of the mounting cover plate 6. Hexagonal socket bolts 19 are inserted into the inner wall of the through slots. The outer wall of the hexagonal socket bolts 19 is threadedly connected to the inner wall of the threaded connecting plate 12. By removing the hexagonal socket bolts 19 and taking off the mounting cover plate 6, the bevel gear set, bearing 10 and rotary joint 13 can be inspected and repaired.
[0024] In actual use, the drive motor 3 on the outer surface of the housing 1 is started. The output end of the drive motor 3 drives the drive shaft 18 to rotate, which drives the second bevel gear 17 to rotate. The rotation of the second bevel gear 17 drives the first bevel gear 15 that meshes with it to rotate, which drives the rotating tube 16 to rotate, which drives the water outlet pipe 4 to rotate. This drives the high-pressure nozzle 5 to achieve 360° rotation cleaning. The cleaning mechanism moves with the robot along the axial or radial direction of the oil tank, covering the entire cleaning area.
