By setting a sealing plate, the sealing ring plate is sealed as a whole to prevent the water source in the sealing ring plate from leaking out.

[0049] By setting a large damping for the rotation of one of the torsion shafts 25 and the sealing plate 24 , it is necessary to use external tools to rotate and adjust the angle, so as to prevent the impact resistance of the water flow from causing the rotation of the torsion shaft 25 .

[0050] As a preferred implementation in this embodiment, refer to the attached Figure 3The same O-shaped sealing ring 13 is installed on the opposite surface of the stabilizing ring plate 12 and the water outlet impeller 10.

[0051] The same O-shaped sealing ring 13 is installed on the opposite surface of the stabilizing ring plate 12 and the water outlet impeller 10 to perform sealing, thereby preventing the liquid from flowing out through the contact surface between the water outlet impeller 10 and the stabilizing ring plate 12 when the water outlet impeller 10 rotates to centrifuge the liquid.

[0052] As a preferred implementation in this embodiment, refer to the attached Figure 1 , Figure 2 The surfaces of the lower protective shell 1, the sealing ring plate 4, the connecting flange 3 and the waterproof box 32 are coated with anti-rust and waterproof coating.

[0053] By coating the surfaces of the lower protective shell 1, the sealing ring plate 4, the connecting flange 3 and the waterproof box 32 with anti-rust and waterproof coating, the surface of the equipment is protected, the service life is extended and the performance degradation caused by rust is prevented.

[0054] The working principle of the present invention is: an energy-saving and flow-increasing submersible pump. When the user needs to adjust the flow rate at the water outlet end of the connecting flange 3 during use, he can adjust one of the marked adjusting blades 26. When one of the adjusting blades 26 rotates, the rotating plate 28 drives one of the linkage plates 29 to rotate, thereby driving the angles of the connected multiple rotating plates 28 to rotate, and controlling the synchronous opening and flipping of the multiple adjusting blades 26. There is a large damping in the rotation of one of the marked adjusting blades 26 and the sealing plate 24, and it is necessary to use external tools to rotate and adjust its angle to prevent the impact resistance of the water flow from causing the rotation of the torsion shaft 25. When in use, by setting the connecting flange 3, it is convenient to fix the connection with the external water pipe, so as to connect the lower protective film to the water pipe. The protective shell 1 is placed in a water source as a whole, and the motor 8 is started to drive the rotating shaft 9 to rotate. The rotating shaft 9 rotates to drive the water outlet impeller 10 to rotate, so that the water outlet impeller 10 uses a centrifugal method to throw out the water source and transport the liquid. While the water outlet impeller 10 rotates, the external seawater is transported to the lower protective shell 1 through the water inlet hole 6 and the water inlet net 30. The water source is transported and discharged through the rotating water outlet impeller 10. The rotating shaft 9 drives the protrusion 14 to rotate while rotating. Since the minimum distance between the protrusion 14 and the surface of the rotating cap 21 is less than the distance from the surface of the force block 22 to the surface of the rotating cap 21, after the rotating shaft 9 rotates to drive the protrusion 14 to rotate, the surface of the protrusion 14 touches the force block 22, so that the force block 22 is driven to rotate the cap 21. The rotation of the rotating cap 21 drives the C-shaped arc rod 15 to rotate, and the rotation of the C-shaped arc rod 15 drives the multiple scraping hooks 16 to move, so as to scrape the dirt blocked in the guide scraping groove 17, and prevent the dirt from clogging the surface of the filter hole 18 and causing the flow rate of the conveyed water source to decrease. When the protrusion 14 rotates and separates from the surface of the force-bearing block 22, the rotating cap 21 is driven by the torsion spring 20 to quickly move and reset, so as to facilitate the next rotation cleaning operation. By setting the torsion spring 20 and the arc plate 11, it is preferably made of stainless steel to prevent the equipment from being immersed in water and causing it to rust and break and lose its function. By installing the O-shaped sealing ring 13 for sealing, it is prevented that when the water outlet impeller 10 rotates to centrifuge the liquid, the liquid flows out through the contact surface between the water outlet impeller 10 and the stabilizing ring plate 12. The inner wall of the waterproof box 32 is fixedly connected with the cooling pipe 7, and the inner wall of the cooling hole 23 is a trapezoidal arc surface, which better fits the surface of the motor 8. At the same time, water flows in through the cooling hole 23 below the cooling pipe 7 and flows out through the cooling hole 23 above the cooling pipe 7, absorbing and driving the temperature of the surface of the motor 8 to cool down. The stabilizing ring plate 12, the mounting plate 31, and the arc plate 11 are installed on one of the lowest water outlet impellers 10 on the surface of the rotating shaft 9. The multiple water outlet impellers 10 on the surface of the rotating shaft 9 rotate to enhance the flow of liquid. With the above structure, the flow rate of the water outlet end is adjusted before use to avoid impurities in the water during transportation to block the inside of the submersible pump, causing damage to the rotating water outlet impeller 10 and reducing the transportation efficiency.

[0055] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments or to make equivalent substitutions for some of the technical features therein.
