[0023] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention 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 invention. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention. The following embodiments are used to illustrate this invention but should not be used to limit the scope of this invention.
[0024] The following is combined with Figure 1 The present invention describes a rocker-arm type underwater column cleaning device for attaching marine organisms, comprising: a mounting frame for connecting a robot 2, the mounting frame having a guide groove; a motor mounted on the mounting frame; a swing arm 103 rotatably connected to the mounting frame and driven by the motor, the swing arm 103 sliding in the guide groove, the motor driving the swing arm 103 to rotate along the guide groove; and a nozzle 111 connected to the swing arm 103 for spraying cleaning water.
[0025] Preferably, the cleaning device uses a motor to drive the swing arm 103 to rotate along the guide groove, allowing the nozzle 111 to flexibly adjust its spray position. This enables comprehensive cleaning of marine organisms attached to the underwater column 3, improving cleaning efficiency and ensuring cleaning quality. The mounting frame design allows the cleaning device to be easily connected to the robot 2, achieving automated cleaning. The use of jet cleaning water eliminates the need for chemical cleaning agents, making it environmentally friendly and in line with the trend of green cleaning.
[0026] In a preferred embodiment of the present invention, a rocker-arm type underwater column cleaning device for attaching marine organisms is described, such as... Figures 1 to 4As shown, the mounting frame includes a base plate 101 and a guide plate 102. The base plate 101 is connected to the robot 2. The guide plate 102 is arc-shaped and connected to the base plate 101. The guide plate 102 has a guide groove. The base plate 101 is designed to be stable and can withstand the forces generated by the motor and the swing arm 103 during operation, ensuring the stability of the cleaning device during operation. The guide groove extends along the arc-shaped trajectory of the guide plate 102, allowing the nozzle 111 to flexibly adjust its spray position along the arc-shaped trajectory of the guide groove, covering a wider cleaning area and further improving cleaning efficiency and quality.
[0027] Preferably, the vertical distance between the top edge of the guide groove and the side of the underwater column 3 is the same, and the vertical distance between the bottom edge of the guide groove and the side of the underwater column 3 is also the same. This ensures that the distance between the nozzle 111 and the underwater column 3 remains consistent as the nozzle moves along the guide groove, thus guaranteeing the uniformity and consistency of the cleaning. The precise size and position setting of the guide groove also ensures that the nozzle 111 can accurately align with various parts of the underwater column 3, avoiding cleaning blind spots and achieving comprehensive and efficient cleaning of marine organisms attached to the underwater column 3.
[0028] Specifically, a pulley 104 is mounted on the top surface of the swing arm 103, and the pulley 104 slides along the top edge of the guide groove. The pulley 104 allows the swing arm 103 to slide smoothly within the guide groove, reducing frictional resistance and improving the flexibility and stability of the swing arm 103's movement. The pulley 104 is made of wear-resistant material, possessing good durability and corrosion resistance, and can maintain stable performance in long-term underwater environments. Furthermore, the pulley 104 fits tightly with the top edge of the guide groove, ensuring that the swing arm 103 does not deviate from the predetermined trajectory during movement, further guaranteeing the accuracy and efficiency of cleaning.
[0029] Preferably, the swing arm 103 includes a circular head and a T-shaped arm. The arm has a connecting groove at the position corresponding to the bottom edge of the guide groove. The connecting groove slides on the bottom edge of the guide groove. The head is connected to the motor, and the pulley 104 is installed on the arm.
[0030] The rounded head allows the swing arm 103 to maintain balance during rotation, reducing vibration and noise caused by its irregular shape and improving the stability and reliability of the entire cleaning device. The T-shaped structure of the arm not only enhances the structural strength of the swing arm 103 but also ensures a good sliding fit with the bottom edge of the guide groove, guaranteeing the stability and accuracy of the swing arm 103 during movement. The connecting groove allows the arm to slide tightly against the bottom edge of the guide groove, limiting the range of motion of the swing arm 103 and preventing damage from excessive movement. It also ensures that the swing arm 103 maintains an appropriate distance from the underwater column 3 during movement, thus achieving precise cleaning of marine organisms attached to the underwater column.
[0031] Preferably, the nozzle 111 can be configured to be one or multiple depending on the usage requirements, thereby improving the cleaning efficiency of the underwater column.
[0032] Specifically, the mounting frame is connected to a hinge 105, and the hinge 105 is connected to a motor plate 106, on which the motor is mounted. The connection between the motor plate 106 and the hinge 105 increases the flexibility of the motor plate 106, allowing the motor to rotate freely and drive the swing arm 103 to swing. This increases the connection flexibility between the motor plate 106 and the mounting frame, and also makes the entire cleaning device more stable during operation.
[0033] Preferably, the combined action of the pulley 104 and the connecting groove prevents the swing arm 103 from swaying due to the reaction force caused by the high-pressure cleaning water jet from the nozzle 111, thus ensuring the stability and quality of the cleaning process and extending the service life of the equipment. The tight fit between the pulley 104 and the connecting groove also ensures that the swing arm 103 does not deviate from its predetermined track during movement, further improving the accuracy and efficiency of the cleaning process.
[0034] Furthermore, the bottom surface of the motor plate 106 is equipped with several boss rollers 112, and the head is slidably connected to the boss rollers 112. The head is slidably connected to the boss rollers 112, and the boss rollers 112 limit the height of the head, so as to prevent the swing arm 103 from deviating when it is subjected to the reaction force of the high-pressure water flow, thereby improving the connection stability between the swing arm 103 and the motor.
[0035] Preferably, the boss roller 112 is connected to the motor plate 106 via the roller seat 113. The boss roller 112 has a roller shaft, and the roller seat 113 has a shaft hole. The boss roller 112 is mounted in the shaft hole via the roller shaft to connect the boss roller 112 and the roller seat 113.
[0036] Specifically, the motor includes a first housing 108 and a second housing 109, an electric motor and a cover plate. The electric motor has a rotating shaft that passes through the motor plate 106 and is driven to the head.
[0037] Preferably, the first housing 108 is cubic and the second housing 109 is cylindrical. The first housing 108 is connected to the motor plate 106, and the second housing 109 is connected to the side of the first housing 108. The motor is a worm gear motor, which mainly includes a motor body and a worm gear structure. The motor body is located in the second housing 109, and the worm gear structure is located in the first housing 108. The cover plate is fastened to the second housing 109 by an interference fit. The through bolt 110 is threaded onto the cover plate to provide a watertight effect. The motor power line enters the motor through the through bolt 110, providing underwater sealing.
[0038] Preferably, the first housing 108 has four mounting holes, and the motor plate 106 has mounting mating holes that correspond one-to-one with the four mounting holes. Bolts are inserted into the corresponding mounting holes and mounting mating holes to connect the motor and the motor plate 106, thereby improving the connection stability between the motor and the motor plate 106.
[0039] A method for cleaning marine organisms attached to an underwater column with a rocker arm includes the following steps: connecting the mounting frame to a robot 2, and connecting the nozzle 111 to the jet pump of the robot 2; the robot 2 moves along the underwater column, and when the robot 2 moves to the position to be cleaned, the motor drives the rocker arm 103 to swing, and the jet pump outputs a high-pressure jet of water, which is sprayed out from the nozzle 111 to clean the marine organisms attached to the side of the underwater column.
[0040] By using high-pressure water jets to remove attached marine organisms from underwater columns, the disturbance to the underwater environment can be effectively reduced, avoiding the damage to the marine ecosystem that traditional cleaning methods may cause. This improves the cleaning efficiency of the underwater column 3, thereby further reducing the danger and cost of offshore operations.
[0041] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention 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; and these 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 the present invention.
