The accelerating shell 1 and the connecting shell 2 are connected and installed with a mounting buoy 4 outside. The inner hollow of the mounting buoy 4 is used to suspend the entire device. The right end surface of the accelerating shell 1 is provided with a thread. The right side of the accelerating shell 1 is sleeved with a connecting ring 5. The inner hollow of the connecting ring 5 is used for water to pass through. A barrier shell 6 with an inner hollow is fixedly installed at the center of the right side surface of the connecting ring 5. Guide baffles 7 are fixedly installed on both the upper and lower sides of the left end of the barrier shell 6. The inner part of the guide baffle 7 is an inverted triangle structure inclined toward the inner part of the barrier shell 6. The upper and lower sides of the barrier shell 6 are provided with card-mounting grooves 8, and the inner parts of the two card-mounting grooves 8 are provided with mounting plug plates 11. The inner part of the mounting plug plate 11 is provided with four equidistantly separated filter ports 12, and the inner part of the filter port 12 is embedded with a filter screen.

[0020] Limiting buckles 9 for limiting are provided under the inner wall surfaces on both sides of the card slot 8, and protrusions corresponding to the inner size of the limiting buckles 9 are provided on the left and right sides of the installation plug plate 11. After the installation plug plate 11 is horizontally inserted into the interior of the card slot 8, the protruding parts on both sides of the installation plug plate 11 will be inserted into the limiting buckles 9 provided on both sides of the card slot 8. At this time, the surface of the installation plug plate 11 is flush with the upper and lower surfaces of the barrier shell 6.

[0021] A mounting shaft 13 is fixedly installed at the upper center of the mounting plug plate 11, and a cleaning fan 14 is installed on the outer sleeve of the mounting shaft 13. Four symmetrical blades are installed on the outside of the cleaning fan 14, and cleaning brushes 15 are installed on the lower ends of the outer blades of the cleaning fan 14. After the screen is embedded in the filter port 12, the cleaning brush 15 contacts the surface of the screen. After the mounting plug plate 11 is installed, the water flow impacts the inside of the guide baffle 7 and enters the card slot 8, which will drive the cleaning fan 14 to move.

[0022] A locking slot 10 is provided on the bottom right side of the card slot 8, and a thread is provided inside the locking slot 10. A locking hole 16 is provided at the center of the right side of the installation plug plate 11. After the installation plug plate 11 is carded into the interior of the card slot 8, the locking hole 16 corresponds to the position of the locking slot 10. A bolt is used to pass through the locking hole 16 and insert it into the interior of the locking slot 10 to complete the positioning and installation of the installation plug plate 11.

[0023] The working principle of this utility model:

[0024] By providing an extended accelerating shell 1 and a fitted connecting collar 5, the internal pipe diameter of the accelerating shell 1 is gradually reduced. After the connecting collar 5 is fitted onto the outside of the threaded tube at the front end of the accelerating shell 1, the connecting collar 5 is connected to the inside of the accelerating shell 1. After the openings on the upper and lower sides of the blocking shell 6 guide the external flowing water into the interior of the accelerating shell 1, the internal pipe diameter of the accelerating shell 1 gradually becomes smaller, the flow radius of the water flow in the accelerating shell 1 gradually decreases, and the kinetic energy of the water flow will gradually increase. The accelerated water flow acts on the impeller of the turbine structure 3 to drive the impeller to rotate. The internal pipe diameter of the connecting shell 2 is gradually increased, so that the water flow can be quickly diffused when discharged. The device can guide the water flow to pass through the impeller of the turbine structure 3 more efficiently, thereby improving the power generation efficiency.

[0025] By providing an installation plug plate 11 that can be automatically cleaned, after the screen is embedded and installed in the four filter ports 12, the cleaning fan 14 is movably installed on the installation shaft 13 set at the bottom of the installation plug plate 11. After the cleaning fan 14 is installed, it can rotate above the installation plug plate 11. The cleaning brush 15 installed below the impeller of the cleaning fan 14 will contact the screen embedded in the filter port 12. After the installation plug plate 11 is inserted into the interior of the card slot 8, the bolt is inserted into the locking slot 10 through the locking hole 16 and locked. When the device is in use, the external water flows through the barrier shell 6. The card-mounting grooves 8 opened on the upper and lower sides enter the interior of the barrier shell 6. During the process of water entering, the water will be washed on the impeller blades of the cleaning fan 14, driving the entire cleaning fan 14 to rotate on the surface of the mounting plug plate 11, so that the cleaning brush 15 scrapes the surface of the screen inside the filter port 12, reducing the accumulation of debris in the running water on the surface of the screen. At the same time, the two guide baffles 7 can guide more running water to enter the interior of the barrier shell 6. During daily use, the device can autonomously clean up the debris remaining on the surface, reduce the accumulation of external debris entering the device, and achieve a better debris removal effect.

The technicians in this industry should understand that the utility model is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model will have various changes and improvements, and these changes and improvements fall within the scope of the utility model to be protected.
