Description

Technical Field

[0001] This invention relates to the field of marine propeller technology, and in particular to a high-efficiency, energy-saving, rectifier protection device for marine propellers. Background Technology

[0002] The ship's propeller is a crucial propulsion component, installed below the waterline at the stern. It uses the power generated by the main engine to rotate, pushing water backward and propelling the ship forward. Due to the unique environment in which ship propellers operate, they are easily entangled in seaweed, which can impair their rotation and cause damage. Therefore, protection is essential.

[0003] Currently, existing ship propellers are protected by protective netting structures, which can prevent foreign objects from getting entangled to some extent. However, small, hard objects cannot be blocked, and they can still impact the propeller, causing damage. Therefore, a high-efficiency, energy-saving, and rectifier protection device for ship propellers is proposed. Summary of the Invention

[0004] The main objective of this invention is to provide a high-efficiency, energy-saving, and rectifier protection device for ship propellers, in order to solve the problems mentioned in the background art.

At the same time, the filter screen installed inside the protective cover can intercept small hard objects such as sand and gravel, preventing them from impacting the propeller, reducing blade wear, and extending its life. The guide channel guides the water flow to flow through the propeller in an orderly manner, reducing water flow resistance, improving propulsion efficiency, and helping the ship save energy.

[0018] 2. The cleaning component uses a motor-driven rotating rod to rotate the propeller, while the cleaning blade rotates and scrapes the back of the filter screen to remove small hard objects that are stuck on the screen in time, preventing the filter screen from becoming clogged and affecting the water flow.

[0029] The front and rear ends of the connecting plate 302 are fixedly connected to the rear side of the protective cover 301 and the surface of the mounting box 2, respectively. Multiple connecting plates 302 are provided and evenly distributed.

[0030] Mounting plate 303 is fixedly connected to the surface of mounting box 2. The rear side of mounting plate 303 is flush with the rear side of mounting box 2. Mounting plate 303 allows the device to be stably mounted on the ship.

[0031] A sealing ring 304 is fixedly connected to the rear side of the mounting box 2. The sealing ring 304 seals the connection between the mounting box 2 and the ship to prevent seawater from entering the interior of the mounting box 2 and causing damage to the parts.

[0032] The protective component 30 and the protective cover 301 enclose the propeller 1, blocking large debris such as weeds. Multiple evenly distributed connecting plates 302 connect the protective cover 301 and the mounting box 2, which not only stabilizes the structure but also further blocks large debris, reducing the risk of propeller 1 getting tangled. At the same time, the filter screen 313 installed inside the protective cover 301 can intercept small hard objects such as sand and gravel, preventing them from impacting the propeller 1, reducing blade wear, and extending its lifespan. The guide channel 315 guides the water flow to flow through the propeller 1 in an orderly manner, reducing water flow resistance, improving propulsion efficiency, and helping the ship save energy.

[0033] Example 2: Based on Example 1, a preferred embodiment of the high-efficiency energy-saving rectification and protection device for ship propellers provided by the present invention is as follows: Figure 1 - Figure 5 As shown: The cleaning assembly 31 includes a filter screen plate 313 fixedly connected to the inside of the protective cover 301, a propeller 1 located in front of the filter screen plate 313, a motor 311 fixedly connected to the inside side of the mounting box 2, and a rotating rod 312 and a cleaning blade 314 provided on the rear side of the filter screen plate 313. The rotating rod 312 and the cleaning blade 314 are located between multiple connecting plates 302.

[0034] The front end face of the output rod of motor 311 extends through the front side of the inside of the mounting box 2 to the front side of the mounting box 2. A sealing ring is fixedly connected to the front side of the inside of the mounting box 2. The surface of the output rod of motor 311 is rotatably and sealed to the inner wall of the mounting box 2 through the sealing ring.

[0035] The front end face of the output rod of motor 311 is fixedly connected to the rear end face of rotating rod 312. The mounting ring of cleaning blade 314 is fixedly sleeved on the surface of rotating rod 312. The front side of rotating rod 312 is slidably connected to the rear side of filter screen plate 313. The front end face of rotating rod 312 extends through the rear side of filter screen plate 313 to the front side of filter screen plate 313. The surface of rotating rod 312 is rotatably connected to the inner wall of filter screen plate 313 through bearing seat. The front end face of rotating rod 312 is fixedly connected to the rear end face of propeller 1.

[0036] The rear side of the mounting box 2 is fixedly connected to a heat dissipation hole, and a filter screen 315 is fixedly connected to the inside side of the heat dissipation hole. The filter screen 315 prevents debris from entering the mounting box 2 through the heat dissipation hole, and the heat dissipation hole facilitates the heat dissipation of the motor 311.

[0037] By using the cleaning component 31, the motor 311 drives the rotating rod 312 to rotate the propeller 1. At the same time, the cleaning blade 315 rotates and scrapes the back of the filter screen 313, promptly removing small hard objects that are blocking the screen and preventing the filter screen 313 from becoming clogged and affecting the water flow. No manual cleaning is required.

[0038] It should be noted that the specific installation method of the motor, the connection method of the circuit, and the control method used in this invention are all conventional designs, and will not be described in detail here.

[0039] The working principle of this invention is as follows:

[0040] Move the mounting box 2 to the installation position on the ship, and use the mounting plate 303 to install the mounting box 2 on the ship. The sealing ring 304 increases the sealing effect between the mounting box 2 and the ship.

[0041] The protective cover 301 and the connecting plate 302 prevent aquatic plants and larger debris from getting tangled on the propeller 1. The filter screen 313 blocks small hard particles, preventing them from hitting the propeller 1. The motor 311 is turned on, and the output rod of the motor 311 drives the rotating rod 312 to rotate. This causes the rotating rod 312 to drive the mounting ring of the cleaning blade 314 and the propeller 1 to rotate. The rotating cleaning blade 314 cleans the surface of the filter screen 313, thereby crushing the small hard particles clogging the surface of the filter screen 313.
