Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of subsea pipeline beveling and grinding devices, specifically, to a subsea pipeline beveling and grinding device with a storage structure. Background Technology
[0002] In the field of marine engineering, the laying and maintenance of subsea pipelines is a critical link. Commonly used methods for laying subsea pipelines include pipe towing and pipelaying vessel methods. Pipe towing is suitable for laying subsea pipelines on land or in the sea, in shallow waters or in short distances. Regardless of the laying method, there is a need to connect multiple sections of subsea pipelines. Welding is the main means of achieving this connection. To ensure welding quality, the pipe ends need to be beveled and then ground. Beveling and grinding are beneficial to the stability of subsequent welding.
[0003] Currently, there are various methods for beveling subsea pipelines. In some cases, manual grinding is used, but this method has many drawbacks. Manual grinding makes it difficult to ensure the neatness of the bevel, which can easily lead to incomplete welding during subsequent welding, resulting in a reduced service life of the pipeline. Moreover, manual grinding is time-consuming, labor-intensive, and extremely inefficient.
[0004] Some conventional beveling and grinding equipment is used, but these devices have revealed some problems in practical applications. For example, during the grinding process, the generated debris usually scatters randomly, and the accumulation of debris can affect the continuous grinding work, reducing grinding efficiency and quality. Existing equipment generally lacks a storage structure, making it impossible to properly collect the debris generated during the grinding process. Subsequent manual cleaning of large areas of debris is time-consuming and laborious, causing inconvenience to users. In view of this, we propose a beveling and grinding device for subsea pipelines with a storage structure. Utility Model Content

[0029] Please see Figures 1-5 This utility model provides a technical solution: a subsea pipeline beveling and grinding device with a storage structure, including a pipeline beveling and grinding machine body 1 and a bottom support panel 10 set at the bottom of the pipeline beveling and grinding machine body 1. The grinding components on the pipeline beveling and grinding machine body 1 are all installed inside the pipeline beveling and grinding machine body 1 and located above the bottom support panel 10. The side of the shell of the pipeline beveling and grinding machine body 1 is provided with a pipeline inlet hole 11 that communicates with the outside. The pipeline is inserted into the pipeline beveling and grinding machine body 1 through the pipeline inlet hole 11 for grinding operation. The pipeline beveling and grinding machine body 1 and its grinding components are all existing conventional technologies, which will not be described in detail here.
[0030] In this embodiment, a perforated plate 12 is integrally formed on the bottom support panel 10. The perforated plate 12 has a mesh-like plate structure, allowing grinding debris to fall through the mesh holes. A debris collection assembly 2 is provided below the perforated plate 12. The debris collection assembly 2 includes a collection cover 20 fixedly installed on the bottom surface of the bottom support panel 10. The perforated plate 12 is located directly above the collection cover 20, collecting the debris falling from the perforated plate 12. A dust inlet pipe 21 is fixedly installed at the bottom end of the collection cover 20. A sealing cover 22 is fixedly installed on the dust inlet pipe 21. A dust baffle is detachably connected to the middle section of the dust inlet pipe 21. The dust screen 262 and the sealing cover 22 are detachably connected to the bottom surface of the outer cylinder 24. A negative pressure suction pump 23 is provided on one side of the outer cylinder 24. A suction pipe 231 is fixedly installed between the suction end of the negative pressure suction pump 23 and the sealing cover 22. The suction pipe 231 is located above the dust screen 262. The negative pressure suction pump 23 draws air between the sealing cover 22 and the outer cylinder 24 through the suction pipe 231 to form a negative pressure, allowing the debris to smoothly enter the outer cylinder 24 through the dust inlet pipe 21, thus achieving efficient collection of grinding debris. In addition, the dust screen 262 prevents the debris from being directly sucked into the negative pressure suction pump 23.
[0031] Specifically, the inner wall of the collection hood 20 is inclined downwards at an angle of 30 to 60 degrees, and the dust inlet pipe 21 is vertically arranged to facilitate the downward fall of debris. Multiple support legs 13 arranged in a matrix are fixedly installed on the bottom surface of the bottom support panel 10 to provide stable support for the device and ensure that it will not shake during the grinding operation. A conical hopper 25 is fixedly installed at the bottom end of the outer cylinder 24, and a discharge pipe 251 is fixedly installed at the bottom end of the conical hopper 25. A discharge valve 252 is fixedly installed on the discharge pipe 251. The distance between the bottom end of the discharge pipe 251 and the ground is greater than 5 cm. Opening the discharge valve 252 can conveniently discharge the collected debris, which is convenient for cleaning up the collected debris and improving work efficiency.
[0032] Furthermore, an upper sealing ring 211 is fixedly installed on the middle section of the dust inlet pipe 21, and an inner ring 26 is fixedly installed at the center of the dust filter 262. The inner ring 26 is detachably installed on the bottom surface of the upper sealing ring 211 by multiple fastening screws. An inner sealing ring 241 is fixedly installed on the inner wall of the outer cylinder 24, and an outer ring 261 is fixedly installed on the outer annular side of the dust filter 262. The outer ring 261 abuts against the upper surface of the inner sealing ring 241, which facilitates installation, disassembly and maintenance operations.
[0033] In addition, multiple support beams 27 are fixedly installed between the inner ring 26 and the outer ring 261. A vibration motor 271 is fixedly installed on the upper surface of the support beam 27. When the vibration motor 271 is working, it drives the dust filter 262 to vibrate, shaking off the debris on the dust filter 262 and ensuring the stable operation of the debris collection system.
[0034] Finally, it should be noted that the negative pressure suction pump 23 and vibration motor 271 of this utility model are all general standard parts or parts known to those skilled in the art. Their structure and principle can be known to those skilled in the art through technical manuals or conventional experimental methods. In the spare parts of this device, all the above-mentioned electrical components, which refer to power elements, electrical components and matching controllers and power supplies, are connected by wires. The specific connection method should refer to the working principle of this utility model. The electrical connections between each electrical component are completed in the order of operation. The detailed connection methods are all technologies known in the art.
[0035] When using the subsea pipeline beveling and grinding device with storage structure of this utility model, first insert the subsea pipeline to be ground through the pipeline insertion hole 11 on the side of the pipeline beveling and grinding machine body 1, then start the grinding component built into the pipeline beveling and grinding operation on the pipeline.
[0036] The debris generated during grinding falls through the mesh of the integrally formed perforated plate 12 on the bottom support panel 10. The collection cover 20 below is installed on the bottom surface of the bottom support panel 10 to receive the debris falling from the perforated plate 12. Since the inner wall of the collection cover 20 is inclined downward at 30 to 60 degrees and the dust inlet pipe 21 is set vertically, the debris can fall smoothly into the dust inlet pipe 21.
[0037] The negative pressure suction pump 23 is started. It draws air between the sealing cover 22 and the outer cylinder 24 through the suction pipe 231, so that a negative pressure is formed in the outer cylinder 24. This further enables the suction of dust in the main body 1 of the pipe bevel grinder. The debris enters the outer cylinder 24 along the dust inlet pipe 21. During this process, the dust baffle 262 prevents the debris from being directly sucked into the negative pressure suction pump 23, so that the debris can only accumulate below the dust baffle 262, thus completing the debris collection operation.
[0038] When it is necessary to clean up the collected debris, the vibration motor 271 on the dust filter 262 works synchronously, driving the dust filter 262 to vibrate and shake off the debris. Then, the discharge valve 252 on the discharge pipe 251 is opened to discharge the debris.
[0039] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
