[0031] It should be noted that the utility model is a kind of urban sewage submersible sewage pump, first, motor 3 is connected with the power supply outside, to power supply to the device.

[0032] When the submersible sewage pump is powered on and started, the output end of the motor 3 drives the rotating rod 10 to rotate. The rotating rod 10, as a key component for power transmission, transmits the power generated by the motor 3 downward. The bottom end of the rotating rod 10 is fixedly connected to the inside of the sleeve 8. The top end of the sleeve 8 is rotatably connected to the inside of the baffle 4. The sleeve 8 penetrates and is connected to the outside of the middle part of the support plate 6. With the rotation of the rotating rod 10, the support plate 6 and the impeller 7 fixedly connected to the top of the support plate 6 are driven to rotate together through the connecting effect of the sleeve 8. The top of the impeller 7 is fixedly connected to the bottom wall of the connecting plate 5. The connecting plate 5 is rotatably connected to the bottom of the baffle 4. This makes the impeller 7 able to rotate stably and smoothly inside the pump body 1.

[0033] When the motor 3 drives the rotating rod 10 to rotate, the connecting rod 11 on the bottom end also rotates synchronously, thereby driving the connecting column 14 and the cutting blade 15 to rotate together. In the process of sewage being sucked into the water inlet pipe 2, the high-speed rotating cutting blade 15 will cut the debris. The cutting blade 15 cuts the larger size debris into smaller fragments or particles, so that these debris can pass through the subsequent pump body components more smoothly, avoiding the blockage of the pump body due to the large size of the debris, and ensuring the normal extraction and transportation of the submersible sewage pump for sewage containing complex components.

[0034] After the pump body 1 of the submersible sewage pump sucks and preliminarily processes the sewage through the impeller and other components, the sewage will be discharged from the right side of the pump body 1 and enter the tapered pipe 16 connected thereto. The tapered pipe 16 plays a role in transitioning and guiding the flow direction of the sewage. It can change the flow pattern of the sewage gradually after it flows out of the pump body 1. The sewage then flows into the first connecting pipe 17 from the right end of the tapered pipe 16. The sewage continues to flow forward in the first connecting pipe 17 until it reaches the right end and enters the delivery pipe 18. The base 19 fixedly connected to the bottom of the delivery pipe 18 provides stable support for the delivery pipe 18, ensuring that it can maintain a fixed position during operation and avoiding the influence of factors such as shaking on the normal transportation of the sewage.

[0035] The base 19 has a connecting buckle 20 threadedly connected to the top end. This connection method is mainly used to stably connect the delivery pipe 18 with other devices or pipelines that may be connected thereto. When other components need to be connected, rotating the connecting buckle 20 can make it tightly combined with the corresponding component, ensuring the sealing and stability of the entire delivery system and preventing leakage of the sewage during transportation.

[0036] In the process of sewage flowing through the conveying pipe 18, it will pass through the filter plate 21 arranged inside the left end. The filter plate 21 plays a role in intercepting solid impurities in the sewage, when the sewage passes through the filter plate 21, part of the sewage intercepted on the left side of the filter plate 21 will flow down along the left side wall of the filter plate 21, at this time, the guide plate 22 guides this part of the sewage to the bottom of the guide plate 22, so that the sewage can reflow into the first connecting pipe 17 and continue to flow down, in the process of sewage passing through the filter plate 21, the solid impurities intercepted will flow into the first connecting pipe 17 under the action of gravity along the guide plate 22, then enter the collecting box 9 through the second connecting pipe 23, the collecting box 9 is used for collecting these impurities, facilitating subsequent cleaning and treatment of the impurities, avoiding accumulation of the impurities in the pipeline system.
