Technical Field

[0001] This utility model relates to the field of underwater operation equipment technology, and in particular to a marine organism removal device for circular channels of marine equipment. Background Technology

[0002] The development of offshore oil and gas reservoirs mainly relies on offshore oil drilling platforms. Due to the complex and changeable marine environment and the diversity of marine life, offshore oil drilling platforms suffer from high wear and tear and have a relatively short lifespan.

[0003] Among the diverse array of marine life, barnacles and other marine organisms particularly favor attaching themselves to rocky surfaces. Their attachment to the support pillars of offshore oil drilling platforms not only exacerbates damage to the pillars but also severely impacts the platform's lifespan. Traditional marine organism removal devices can only remove deposits from the outer surface of the support pillars, failing to reach confined spaces such as connection holes. Therefore, in-depth research into cleaning techniques for marine organisms attached to the connection holes of offshore oil drilling platform support pillars has become a crucial approach to extending the platform's service life.

[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model. The following embodiments are used to illustrate this utility model but should not be used to limit its scope.

[0022] The following is combined Figures 1 to 3 This invention describes a marine organism removal device for a circular channel in marine equipment, comprising: Rotary connecting plate 1; The rotating arm 2 is arbitrarily connected to the rotary connecting plate 1. The height and angle of the rotating arm 2 are adjustable. A first motor 3 is connected to the rotary connecting plate 1 and drives the rotary connecting plate 1 to rotate axially. The second motor 5 is connected to the rotary connecting plate 1 and is used to drive the rotating arm 2 to move along the height direction.

[0023] This marine organism removal device can be mounted on an underwater robot. The underwater robot moves the marine organism removal device to the circular channel to be removed, and then inserts the rotating connecting plate 1 and the rotating arm 2 into the circular channel. The second motor 5 then adjusts the height and angle of the rotating arm 2 so that the end of the rotating arm 2 fits against the inner wall of the circular channel. The first motor 3 then drives the rotating connecting plate 1 to rotate, thereby driving the rotating arm 2 to rotate, so that the rotating arm 2 removes the marine organisms in the circular channel.

[0024] During operation, the extension of the rotating arm 2 can be flexibly adjusted according to the actual inner diameter of the circular channel. If the inner diameter of the channel is large, the second motor 5 can adjust the rotating arm 2 to a larger extension range, ensuring that the end of the rotating arm 2 can fully cover and fit against the inner wall of the channel; if the inner diameter of the channel is small, the second motor 5 will correspondingly reduce the extension of the rotating arm 2 to avoid damaging the channel structure due to excessive extension of the rotating arm 2. At the same time, the rotation speed of the rotating connecting plate 1 driven by the first motor 3 can also be adjusted according to the tightness of the marine organisms attached. When the marine organisms are firmly attached, the rotation speed of the rotating connecting plate 1 can be appropriately reduced, so that the rotating arm 2 has more time and force to remove the marine organisms; if the marine organisms are loosely attached, the rotation speed can be increased to improve the removal efficiency.

[0025] In a preferred embodiment of this utility model, a marine organism removal device for circular channels in marine equipment is described, such as... Figure 1 , Figure 2 and Figure 3 As shown, the first motor 3 has a rotatable first motor shaft, the first motor shaft is connected to a first gear 31, and a second gear 32 is installed on the top of the rotary connecting plate 1. The first gear 31 and the second gear 32 are meshed together.

[0026] Preferably, through the meshing connection of the first gear 31 and the second gear 32, when the first motor 3 is started, the first motor shaft drives the first gear 31 to rotate. Since the first gear 31 and the second gear 32 mesh with each other, the rotation of the first gear 31 drives the second gear 32 to rotate, thereby causing the rotary connecting plate 1 connected to the second gear 32 to rotate as well. This gear transmission method can ensure the stability and accuracy of power transmission, enabling the rotary connecting plate 1 to rotate at a preset speed and direction.

[0027] Preferably, the diameter of the first gear 31 is smaller than the diameter of the second gear 32. When the first motor shaft drives the first gear 31 to rotate, because the diameter of the first gear 31 is smaller than that of the second gear 32, at the same rotational speed, the rotational speed of the second gear 32 will be lower than that of the first gear 31, while the torque will increase accordingly. This is very advantageous for removing marine organisms from the circular channels of marine equipment. The larger torque can provide stronger rotational force to the rotary connecting plate 1, making the rotating arm 2 more effective at removing firmly attached marine organisms. At the same time, this deceleration design also helps to improve the stability of the device operation, reduce vibration and wear that may be caused by excessive rotational speed, and extend the service life of the device. In addition, the smaller first gear 31 is more flexible when rotating, and can quickly respond to the start and stop commands of the first motor 3, making it easier for operators to adjust the rotational state of the rotary connecting plate 1 according to the actual situation, further improving the efficiency and quality of marine organism removal.

[0028] Preferably, a slewing bearing 4 is provided between the slewing connecting plate 1 and the second gear 32. The slewing bearing 4 enables an effective connection between the slewing connecting plate 1 and the second gear 32.

[0029] Specifically, there are two rotary connecting plates 1. The rotary connecting plate 1 has a first guide hole 11 that extends along the length direction. The rotary connecting plate 1 has a second guide hole 12 that is arc-shaped. A first shaft 13 is respectively inserted into the two first guide holes 11. The first shaft 13 is driven and connected to the second motor 5. The rotating arm 2 has two parts. The rotating arm 2 is connected to the first shaft 13. The two rotating arms 2 are respectively attached to the two rotary connecting plates 1. The rotating arm 2 has a second shaft 21 on the side corresponding to the second guide hole 12. The second shaft 21 is slidably disposed in the second guide hole 12.

[0030] Preferably, when the second motor 5 is started, the first shaft 13 is driven to move linearly along the first guide hole 11. At the same time, since the second guide hole 12 is arc-shaped, the second shaft 21 is driven to slide along the second guide hole 12, thereby causing the rotating arm 2 to rotate, so that the two rotating arms 2 can abut against the inner wall of the circular channel.

[0031] Specifically, a rotating nut 52 is provided between the two first shafts 13; the second motor 5 has a rotatable second motor shaft, the second motor shaft is connected to a lead screw 51, and the rotating nut 52 is screwed onto the lead screw 51.

[0032] Preferably, when the second motor shaft rotates, the lead screw 51 rotates accordingly. Since the rotating nut 52 is screwed onto the lead screw 51, the rotation of the lead screw 51 causes the rotating nut 52 to move linearly along the axial direction of the lead screw 51. The rotating nut 52 is positioned between the two first shafts 13, and the linear movement of the rotating nut 52 drives the two first shafts 13 to move synchronously. This transmission method using the lead screw 51 and rotating nut 52 provides high transmission accuracy and stability, ensuring the accuracy and reliability of the rotating arm 2's movement and improving the working efficiency and quality of the marine organism removal device.

[0033] Preferably, the second motor 5 is an encoder motor. An encoder motor can provide real-time feedback of information such as rotation angle and speed, enabling more precise control of the rotation of the lead screw 51, and thus accurately controlling the linear movement distance and speed of the rotating nut 52 along the axial direction of the lead screw 51.

[0034] Preferably, the bottom end of the lead screw 51 is lower than the bottom end of the first guide hole 11, thereby preventing the rotating nut 52 from disengaging from the lead screw 51 and improving the connection stability between the rotating nut 52 and the lead screw 51.

[0035] Preferably, a limiting ring 22 is provided at the end of the second shaft 21. The limiting ring 22 fits against the rotating arm 2, thereby allowing the second shaft 21 to slide stably within the second guide hole 12, thus ensuring that the rotating arm 2 can rotate stably.

[0036] In one specific implementation, the marine organism removal device is equipped on an underwater robot. The underwater robot moves the marine organism removal device to the circular channel to be removed, and then inserts the rotary connecting plate 1 and the rotating arm 2 into the circular channel. Then, the second motor 5 is started, driving the lead screw 51 to rotate, which in turn drives the rotating nut 52 to move linearly along the axis of the lead screw 51. This causes the first shaft 13 to move linearly along the first guide hole 11. At the same time, since the second guide hole 12 is arc-shaped, the second shaft 21 is driven to slide along the second guide hole 12, thereby causing the rotating arm 2 to rotate. This allows the two rotating arms 2 to abut against the inner wall of the circular channel. Then, the first motor 3 is started, driving the rotary connecting plate 1 to rotate, which in turn drives the rotating arm 2 to rotate, so that the rotating arm 2 can remove the marine organisms in the circular channel.

[0037] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
