Installation frame for wastewater treatment pipeline

Abstract

The present invention relates to the technical field of offshore oil engineering, and discloses an installation frame for wastewater treatment pipelines, including a wastewater treatment pipeline cylinder. An annular groove is formed on the outer edge of the wastewater treatment pipeline cylinder, and a first annular clamping frame is clamped on the inner wall of the annular groove. The bottom of the first annular clamping frame is fixedly assembled with a second annular clamping frame by screws. For the installation frame of this wastewater treatment pipeline, through the combined use of the first annular clamping frame and the first round rod, when the wastewater treatment pipeline cylinder moves with the hull and is affected by waves and undergoes displacement, the first round rod drives the sliding cylinder to move towards the direction of the clamping block. At this time, the air flow inside the sliding cylinder enters the inside of the airbag through the inner wall of the round groove and pushes the airbag to form extrusion on the outer edge of the first round rod, shortening the moving distance of the first round rod. Then, by using the combined use of the annular magnet and the outer cylinder, the fixed magnets on the inner wall of the outer cylinder and the outer edge of the inner cylinder repel the annular magnet, thereby driving the first annular clamping frame to drive the wastewater treatment pipeline cylinder to shorten the moving distance.

Description

Technical Field

[0001] The present invention relates to the technical field of offshore oil engineering, and specifically to an installation frame for wastewater treatment pipelines. Background Art

[0002] An offshore floating production storage and offloading vessel is a ship that integrates production treatment, storage and external transportation, as well as living and power supply. Wastewater treatment pipelines need to be installed inside the storage and offloading vessel, thus a kind of wastewater treatment pipeline is required.

[0003] Most of the traditional installation frames for wastewater treatment pipelines have simple devices and single structures. On the one hand, during the use of traditional wastewater treatment pipelines, the storage and offloading vessel is affected by sea waves, resulting in wave bending moments affecting the hogging wave bending moment and sagging wave bending moment, thereby causing the wastewater treatment pipeline to shift. On the other hand, during the use of traditional wastewater treatment pipelines, affected by the internal stress of the hull movement, the installation frame forms stress on the wastewater treatment pipeline, making the wastewater treatment pipeline unable to float with the waves. As a result, after long-term use of the installation frame, it causes damage to the wastewater treatment pipeline and affects the service life of the device. Summary of the Invention

[0004] The present invention provides an installation frame for wastewater treatment pipelines, which has the advantages of assisting in limiting the wastewater treatment pipeline, avoiding pipeline displacement, enabling the pipeline to float with the waves, and reducing the influence of the installation frame on the pipeline, and solves the problems that the wastewater pipeline of the traditional device is prone to displacement and the installation frame causes extrusion damage to the pipeline.

[0005] The present invention provides the following technical solution: An installation frame for wastewater treatment pipelines, including a wastewater treatment pipeline cylinder. An annular groove is opened on the outer edge of the wastewater treatment pipeline cylinder. The inner wall of the annular groove is clamped with a first annular clamping frame.

[0007] As a preferred technical solution of the present invention, a sliding cylinder is fixedly assembled on the outer edge of the first round rod. The inner wall of the sliding cylinder is slidably connected to the outer edge of the inner cylinder. An outer cylinder is fixedly assembled on the side of the clamping block. The inner wall of the outer cylinder is slidably connected to the outer edge of the sliding cylinder.

[0008] As a preferred technical solution of the present invention, an annular magnet is fixedly assembled on the side surface of the sliding cylinder. The S pole of the annular magnet is slidably connected to the outer edge of the inner cylinder, and the N pole of the annular magnet is slidably connected to the inner wall of the outer cylinder. A fixed magnet is arranged between the outer edge of the inner cylinder and the inner wall of the outer cylinder, and the S pole of the fixed magnet is fixedly assembled with the outer edge of the inner cylinder.

[0009] As a preferred technical solution of the present invention, a third annular clamping frame is fixedly assembled at the bottom of the clamping block. The bottom of the third annular clamping frame is fixedly assembled with a fourth annular clamping frame through screws. The inner wall of the third annular clamping frame is fixedly sleeved with the outer edge of the wastewater treatment pipe cylinder.

[0010] As a preferred technical solution of the present invention, a second round rod is fixedly assembled at the bottom of the fourth annular clamping frame. A pressing block is fixedly assembled at the bottom of the second round rod. A through groove is formed at the top of the pressing block. A first cover plate is rotatably connected to the bottom of the pressing block, and a second cover plate is rotatably connected to the top of the pressing block.

[0011] As a preferred technical solution of the present invention, a secondary cylinder is slidably connected to the outer edge of the second round rod. A first notch is formed at the top of the secondary cylinder. A third cover plate is rotatably connected to the top of the secondary cylinder. A second notch is formed at the bottom of the secondary cylinder. A fourth cover plate is rotatably connected to the bottom of the inner wall of the secondary cylinder.

[0012] As a preferred technical solution of the present invention, a first main cylinder is slidably connected to the outer edge of the second round rod.

[0014] The present invention has the following beneficial effects:

[0015] 1. For the mounting rack of the wastewater treatment pipe, through the combined use of the first annular clamping frame and the first round rod, when the wastewater treatment pipe cylinder is affected by waves and displaced as the hull moves, the first round rod drives the sliding cylinder to move towards the clamping block. At this time, the airflow inside the sliding cylinder enters the inside of the airbag through the inner wall of the round groove and pushes the airbag to form extrusion on the outer edge of the first round rod, shortening the moving distance of the first round rod. Then, by using the combined use of the annular magnet and the outer cylinder, the fixed magnets on the inner wall of the outer cylinder and the outer edge of the inner cylinder repel the annular magnet, thereby driving the first annular clamping frame to drive the wastewater treatment pipe cylinder to shorten the moving distance.

[0016] 2. The mounting frame of the wastewater treatment pipeline, through the combined use of the fourth annular clamping frame and the second round rod, when the wastewater treatment pipeline cylinder moves up and down under the influence of waves, the second round rod moves downward and drives the pressing block to move up and down. At this time, the liquid inside the auxiliary cylinder moves up and down inside the auxiliary inner cylinder, and then through the auxiliary limiting of the limiting plate and the spring, the force of the up and down movement of the wastewater treatment pipeline cylinder is consumed, and the loss of the device to the outer edge of the wastewater treatment pipeline cylinder is reduced.

[0026] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0027] Please refer to Figure 1-8 , the mounting bracket of the wastewater treatment pipeline, including the wastewater treatment pipeline cylinder 1. An annular groove 2 is provided on the outer edge of the wastewater treatment pipeline cylinder 1. A first annular clamping frame 3 is clamped on the inner wall of the annular groove 2. The bottom of the first annular clamping frame 3 is fixedly assembled with a second annular clamping frame 28 by screws. The inner wall of the second annular clamping frame 28 is clamped with the inner wall of the annular groove 2. A first round rod 4 is fixedly assembled on the side of the first annular clamping frame 3. A push block 5 is fixedly assembled on the side of the first round rod 4. An inner cylinder 6 is slidably connected to the outer edge of the first round rod 4. A clamping block 11 is fixedly assembled on the side of the inner cylinder 6. By the combined use of the annular groove 2 and the first annular clamping frame 3, when the wastewater treatment pipeline cylinder 1 is affected by waves inside the hull and its position shifts, the first round rod 4 is driven by the first annular clamping frame 3 to move inside the inner cylinder 6. Through the fixation of the screws, the first annular clamping frame 3 and the second annular clamping frame 28 stably clamp the wastewater treatment pipeline cylinder 1. Affected by waves inside the hull, since the wastewater treatment pipeline is used in a floating production, storage and offloading vessel, the ship will swing between the sagging deformation state and the hogging deformation state, forming a tensile force on the pipeline. The magnitude of this tensile force is related to the magnitude of the hogging and sagging deformation. This magnitude change is called the hogging and sagging value. The calculation formula for the hogging and sagging value is:

[0028] dm = (dF + dA) / 2.

[0029] As Figure 7 shown, a circular groove 7 is provided on the side of the inner cylinder 6. An airbag 8 is arranged on the side of the inner wall of the inner cylinder 6. The inner wall of the circular groove 7 is communicated with the inside of the airbag 8. By the combined use of the circular groove 7 and the airbag 8, when the first round rod 4 drives the sliding cylinder 10 to move, the air flow inside the sliding cylinder 10 enters the inside of the airbag 8 through the inner wall of the circular groove 7, thereby pushing the outer edge of the airbag 8 to form friction with the outer edge of the first round rod 4, slowing down the moving speed of the first round rod 4.

[0030] As Figure 7 shown, a sliding cylinder 10 is fixedly assembled on the outer edge of the first round rod 4. The inner wall of the sliding cylinder 10 is slidably connected to the outer edge of the inner cylinder 6. An outer cylinder 21 is fixedly assembled on the side of the clamping block 11. The inner wall of the outer cylinder 21 is slidably connected to the outer edge of the sliding cylinder 10. By the combined use of the inner cylinder 6 and the outer cylinder 21, the outer edge of the inner cylinder 6 and the inner wall of the outer cylinder 21 assist in limiting the sliding cylinder 10, making the sliding cylinder 10 and the first round rod 4 move stably.

[0031] As shown in Figure 7 and Figure 8 shown, an annular magnet 12 is fixedly assembled on the side surface of the sliding cylinder 10. The S pole of the annular magnet 12 is slidably connected to the outer edge of the inner cylinder 6, and the N pole of the annular magnet 12 is slidably connected to the inner wall of the outer cylinder 21. A fixed magnet is provided between the outer edge of the inner cylinder 6 and the inner wall of the outer cylinder 21, and the S pole of the fixed magnet is fixedly assembled with the outer edge of the inner cylinder 6. By adding the annular magnet 12, when the annular magnet 12 moves in the same direction as the sliding cylinder 10, the S pole of the fixed magnet on the outer edge of the inner cylinder 6 repels the S pole of the annular magnet 12, and the N pole of the fixed magnet on the inner wall of the outer cylinder 21 repels the N pole of the annular magnet 12, so that the first round rod 4 assists in limiting the wastewater treatment pipe cylinder 1 through the first annular card frame 3.

[0032] As shown in Figure 1 and Figure 7 shown, a third annular card frame 13 is fixedly assembled at the bottom of the clamping block 11. The bottom of the third annular card frame 13 is fixedly assembled with a fourth annular card frame 14 through screws. The inner wall of the third annular card frame 13 is fixedly sleeved with the outer edge of the wastewater treatment pipe cylinder 1. By using the third annular card frame 13 and the fourth annular card frame 14 in cooperation, the third annular card frame 13 and the fourth annular card frame 14 are fixed by screws, and the wastewater treatment pipe cylinder 1 is stably clamped.

[0033] As shown in Figure 3 shown, a second round rod 15 is fixedly assembled at the bottom of the fourth annular card frame 14. A pressing block 23 is fixedly assembled at the bottom of the second round rod 15. A through groove 24 is formed at the top of the pressing block 23. A first cover plate 25 is rotatably connected to the bottom of the pressing block 23, and a second cover plate 26 is rotatably connected to the top of the pressing block 23. By using the second round rod 15 and the pressing block 23 in cooperation, when the wastewater treatment pipe cylinder 1 moves up and down with the waves, the second round rod 15 and the pressing block 23 are driven to move up and down. When the pressing block 23 moves down, the second cover plate 26 moves up, and the top of the first cover plate 25 fits and overlaps with the inner wall of the through groove 24. When the pressing block 23 moves up, the bottom of the second cover plate 26 fits and overlaps with the inner wall of the through groove 24, and the first cover plate 25 moves down.

[0034] As shown in Figure 3As shown, a secondary cylinder 19 is slidably connected to the outer edge of the second round rod 15. A first notch 20 is formed at the top of the secondary cylinder 19. A third cover plate 22 is rotatably connected to the top of the secondary cylinder 19. A second notch 27 is formed at the bottom of the secondary cylinder 19. A fourth cover plate 29 is rotatably connected to the bottom of the inner wall of the secondary cylinder 19. Liquid is added inside the secondary cylinder 19. The second round rod 15 drives the pressing block 23 to move up and down inside the secondary cylinder 19. When the pressing block 23 moves upward, the third cover plate 22 on the top of the secondary cylinder 19 moves upward, so that the liquid inside the secondary cylinder 19 enters the inside of the first main cylinder 18 through the first notch 20, and the liquid inside the first main cylinder 18 enters the secondary cylinder 19 through the second notch 27 at the bottom of the secondary cylinder 19.

[0035] As Figure 3 As shown, a first main cylinder 18 is slidably connected to the outer edge of the second round rod 15. A deck 30 is fixedly assembled at the bottom of the first main cylinder 18. A spring 17 is fixedly connected to the top of the first main cylinder 18. The top of the spring 17 is fixedly connected to a limit plate 16. The inner wall of the limit plate 16 is fixedly assembled with the outer edge of the second round rod 15. By the combined use of the spring 17 and the first main cylinder 18, the limit plate 16 is used to assist in limiting the second round rod 15, avoiding excessive movement of the second round rod 15, which may cause the outer edge of the wastewater treatment pipe cylinder 1 to collide with the top of the first main cylinder 18.

[0036] As Figure 1 As shown, a third round rod 32 is fixedly assembled at the top of the third annular clamping frame 13. The outer edge of the third round rod 32 is slidably connected to a second main cylinder 9. The internal structure of the second main cylinder 9 is exactly the same as that of the first main cylinder 18. A top plate 31 is fixedly assembled at the top of the second main cylinder 9. By adding the second main cylinder 9, the second main cylinder 9 and the first main cylinder 18 are used in combination to assist in limiting the wastewater treatment pipe cylinder 1.

[0037] Working principle: When the device needs to be used, the wastewater treatment pipe cylinder 1 moves under the influence of waves. When the wastewater treatment pipe cylinder 1 moves up and down, the second round rod 15 drives the pressing block 23 to move up and down. At this time, the liquid inside the secondary cylinder 19 resists the pressing block 23. When the second round rod 15 moves upward, the third cover plate 22 moves upward, so that the liquid inside the secondary cylinder 19 enters the inside of the first main cylinder 18 through the first notch 20, and then enters the secondary cylinder 19 through the second notch 27 at the bottom of the secondary cylinder 19. When the wastewater treatment pipe cylinder 1 moves left and right, the first round rod 4 drives the push block 5 to move inside the inner cylinder 6. At this time, the gas inside the sliding cylinder 10 enters the inside of the airbag 8 through the circular groove 7. Then, the outer edge of the airbag 8 forms friction with the outer edge of the first round rod 4, and the annular magnet 12 and the fixed magnet on the inner wall of the outer cylinder 21 form repulsion to push the wastewater treatment pipe cylinder 1.
