Description

Technical Field

[0001] This utility model relates to the field of marine engineering jet technology, specifically a jet device that is easy to adjust the distance. Background Technology

[0002] In marine engineering, jet devices typically generate mechanical energy and hydraulic effects through high-speed fluids (water, gas, or mixed media), playing a crucial role in complex marine environments. Their main functions include cleaning hulls and structures, and maintaining submarine pipelines and cables.

[0003] Currently, most marine engineering jet devices are carried to the seabed by hand by workers, who then clean both sides of the ship's hull. This process is quite cumbersome, and the practicality of current marine engineering jet devices is relatively low. Utility Model Content

[0004] To address the shortcomings of existing technologies, this invention provides a jet device with easily adjustable distance, thus solving the problems mentioned in the background section.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a jetting device with adjustable distance, comprising a device box and a jetting nozzle. A motor is fixedly installed inside the device box. A first groove is provided on the top of the device box. A rotating shaft is rotatably connected inside the first groove. The output end of the motor is fixedly connected to the rotating shaft via a coupling. A take-up roller is fixedly connected to the outside of the rotating shaft. A connecting rope is wound around the outside of the take-up roller. An installation ring is fixedly installed on one side of the jetting nozzle. The installation ring is wound around one end of the connecting rope.

[0006] Preferably, the bottom of the device box has a second groove. Several compression springs are fixedly installed on one side of the second groove. One end of each compression spring is connected to a movable plate. Several movable shafts are fixedly installed on one side of the movable plate. One end of each movable shaft extends through the compression springs to the outside of the device box and is fixedly connected to a connecting plate. The movable shafts are slidably connected to the device box. Several sliding wheels are fixedly installed on one side of the movable plate. Two sliding wheels cooperate with each other. By pulling the two connecting plates, the compression springs undergo elastic deformation, increasing the distance between the two sliding wheels and allowing the device to be installed at the edge of the hull. At this point, the two connecting plates are released, allowing the sliding wheels to contact the edge of the hull, thus facilitating the device's integration with the hull and enabling easy movement, improving the device's practicality.

[0007] Preferably, a handle is fixedly installed on one side of each of the two connecting plates, and square slots are provided on both sides of the device box. The two handles facilitate the worker to pull the two connecting plates to the sides, and the two square slots enable the worker to carry and move the device.

[0008] Preferably, the ejector has two screw holes on its outer side, and a sliding ring is slidably connected to the outer side of the ejector. Two bolts are threadedly connected to the outer side of the sliding ring. One end of each bolt passes through the sliding ring and extends into the screw hole and is threadedly connected to it. By having the two bolts pass through the sliding ring and screw into the two screw holes, the installation and removal of the lighting lamp can be achieved.

[0009] Preferably, two fixing blocks are fixedly installed on the outer side of the sliding ring, and a light is fixedly installed on one side of each of the two fixing blocks. The two lights provide a clearer field of vision for the workers when cleaning the attachments on both sides of the bottom of the boat, thus avoiding the situation where the attachments remain on both sides of the bottom of the boat after cleaning.

[0010] This invention provides a jet device that facilitates distance adjustment, and has the following beneficial effects: 1. This adjustable jetting device, activated by a motor, rotates the rotating shaft and the take-up roller. The rotation of the take-up roller allows for the retrieval or release of the connecting rope. This eliminates the need for workers to hold the jetting device while cleaning attachments at sea, making the process more convenient. Simultaneously, pulling the two connecting plates causes several compression springs to deform elastically, increasing the distance between the two sliding wheels. When the device is installed at the edge of the hull, releasing the two connecting plates allows the sliding wheels to contact the hull edge, facilitating easy integration with the hull and movement, thus enhancing the device's versatility.

[0011] 2. This jet device, which allows for easy adjustment of the distance, provides workers with a clear view when cleaning the attached materials on both sides of the hull through two lights, thus preventing the materials from remaining on both sides of the hull after cleaning.

A connecting rope 3 is wound around the outside of the take-up roller 17. An installation ring 4 is fixedly installed on one side of the jet injector 5. The installation ring 4 is wound around one end of the connecting rope 3.

[0016] The bottom of the device box 1 has a second groove 22. Several compression springs 15 are fixedly installed on one side of the second groove 22. One end of the compression springs 15 is connected to a moving plate 14. Several movable shafts 12 are fixedly installed on one side of the moving plate 14. One end of the movable shafts 12 passes through the compression springs 15 and extends to the outside of the device box 1, where they are fixedly connected to a connecting plate 11. The movable shafts 12 are slidably connected to the device box 1. Several sliding wheels 13 are fixedly installed on one side of the moving plate 14. The two sliding wheels 13 cooperate with each other. By pulling the two connecting plates 11, the compression springs 15 undergo elastic deformation, increasing the distance between the two sliding wheels 13 and allowing the device to be installed at the edge of the hull. At this time, the two connecting plates 11 are released, allowing the sliding wheels 13 to contact the edge of the hull, thereby facilitating the device's cooperation with the hull and making it easy to move, thus improving the device's practicality.

[0017] A handle 10 is fixedly installed on one side of each of the two connecting plates 11, and square slots 16 are provided on both sides of the device box 1. The two handles 10 facilitate the workers to pull the two connecting plates 11 to the sides, and the two square slots 16 enable the workers to carry and move the device.

[0018] Two screw holes 18 are opened on the outer side of the jet injector 5. A sliding ring 7 is slidably connected to the outer side of the jet injector 5. Two bolts 6 are threadedly connected to the outer side of the sliding ring 7. One end of each bolt 6 passes through the sliding ring 7 and extends into the interior of the screw hole 18 and is threadedly connected to it.

[0020] In summary, this jetting device, which allows for easy distance adjustment, has a jetting nozzle 5 brand name of Sapphire Blue and model number QSB. When cleaning deposits on both sides of the hull bottom, the worker first holds the two handles 10 by hand and pulls them to both sides, causing several compression springs 15 to elastically deform, increasing the distance between the two sliding wheels 13. Then, another worker installs the device box 1 on the hull railing, followed by installing the sliding ring 7 on the outside of the jetting nozzle 5. The worker then uses a tool to screw two bolts 6 through the sliding ring 7 into the two screw holes 18, thus achieving the purpose of installing the lighting lamp 8 onto the jetting nozzle 5. Finally, the worker... The connecting rope 3 on the roller 17 is wound around the jet ejector 5 and the mounting ring 4. When the workers go into the sea to clean the attachments on both sides of the bottom of the boat, another worker starts the motor 21, which makes the rotating shaft 20 and the take-up roller 17 rotate, and lowers the jet ejector 5 into the sea. Then the workers hold the jet ejector 5 and start it to clean the attachments on both sides of the bottom of the boat. When the attachments on one side of the bottom of the boat are cleaned, another worker moves it by contacting the surface of the hull railing with several sliding wheels 13. When the cleaning work is completed, the workers start the motor 21 again, which makes the take-up roller 17 retract the connecting rope 3 and then disassemble the jet ejector 5.
