It can suck in the bottom of the seaweed to clean and environmentally friendly
Tencent Digital (Wang John) has long-term navigation in the sea. The part that is soaked in seawater makes it easy for algae, barnacles, and other plankton-like creatures to spread on the ship and affect the speed of ships. The hull causes corrosion. Keelcrab is an underwater robot that can clean the part of the hull that is underwater, without increasing maintenance costs. And by using it, you can also save fuel and improve performance.
Dalarobatvard was the first company to use this underwater robot and received a 50% subsidy at the Swedish Maritime Administration, because Keelcrab has been considered as an environmentally friendly product that helps to improve water pollution. Gothenburg University also invited the company to evaluate the KeelCrab robot on the experimental ship Hrimfare. At present, the company has established maintenance stations in 10 ports. By using the Keelcrab underwater robot to maintain the hull, this method of removing hull attachments will become increasingly popular. More and more shipping companies have chosen Use this method to clean the hull.
Keelcrab is an underwater robot that can perform cleaning and hull inspections. It is designed to be used primarily for cleaning sailboats (of any size), and the hull of yachts and large yachts, particularly in the underwater part, is particularly satisfactory for cleaning inspections. The main function of the robot is to remove the plankton and plants that have existed on the surface of the hull for a long time, so as to carry out overall conservation of the underwater part of the hull.
The easiest thing to do with Keelcrab is to be able to clean the underwater part without dragging the boat to the shore. Its fuselage uses a plastic frame, using hydrostatic principles to maintain balance, the whole weight of 9.5 kg, the size of 42.5 × 42.5 × 32 cm, the cleaning speed of 1.5 square meters per minute. The robot uses a built-in brushless motor to drive the turbine blade to generate a vacuum suction force, so that it can be firmly adsorbed on the hull and can remove seaweeds attached to the hull. The rubber brush can drive the robot to move in all directions.
The operation of this robot is also very simple, even children can quickly learn how to operate. The robot is equipped with a wireless remote control and IP68 waterproof camera with LED lighting. By looking at the screen, you can use the directional buttons on the remote control to control the movement of the robot, while also being able to check the condition of the hull. The Keelcrab robot has a cleaning speed of 1.5 square meters per hour. It takes about 50 minutes to clean a 12-meter-long hull. It takes about 80 minutes to clean a 15-meter hull, and it takes about 110 minutes to clean a 18-meter hull.
Cleaning the hull with the Keelcrab robot is a green cleaning solution that helps protect the marine environment. First of all, it's very efficient, equipped with soft, medium, and hard grades of certified nylon hair brushes. This brush will not destroy the anti-fouling paint applied to the hull, and of course it will not be able to remove the organisms attached to the hull and only remove the plants growing on the hull. When the plants began to grow on the hull, the antifouling coating had begun to lose its effect. Tests have shown that the removal of the first layer of algae (thickness about 3 mm) significantly extends the life of the antifouling coating. At this time, arthropods such as barnacles cannot attach to the hull because vegetation such as algae cannot grow. This method can not only make the hull cleaner, but also reduce fuel consumption. After cleaning, it will reduce fuel consumption by 20%.
Comparing the costs of using Keelcrab robots with traditional antifouling coatings, the Keelcrab robots are less expensive to maintain and will not pollute the seawater environment. And the robot is very convenient to use, without the need to pull the boat off the water, targeted cleaning of the need to clean the site to maintain the best performance of the ship.
The Keelcrab robot is also equipped with a dirt collection bag. The dirt that is removed from the hull is natural compound. However, by installing these dirt in the collection bag, the surface of the water can be kept clean and the sea water can be prevented from being polluted. Under normal circumstances, after the completion of the cleaning of the hull, the vessel should be allowed to sail immediately, so that the cleaned dirt can be prevented from attaching to the ship again. With the dirt collection bag there is no need to worry about this problem. The antifouling coating will cause certain pollution to the seawater. If the Keelcrab robot is regularly used to clean the seaweed, it will reduce the use of antifouling coating by 80%, and it can improve the seawater quality while ensuring the antifouling performance of the hull. Marine life plays a role in indirect protection.
The Keelcrab Robotics package includes a host, camera, 2 LED lights (200 lumens each), a medium nylon brush and an operating handle. Currently, this device is being crowdfunded on the Kickstarter website. The discounted price for early adopters is 1299 Euro (approximately RMB 9527), and shipment is expected to begin in June 2017.
