[0010] By employing the above technical solution, this utility model provides a low-water-level pump, which has at least the following beneficial effects: 1. This utility model enables the device to effectively pump out shallow water by setting up a pump shaft and a suction pipe. By placing the device in the working area, the suction pipe is in contact with the shallow water surface. The pump shaft drives the vortex impeller to rotate, thereby producing a suction effect on the shallow water. The reamer blades effectively cut impurities in the shallow water, and the filter screen filters the impurities, greatly reducing the blind spot of the pump and enabling the water to be effectively pumped out.

[0011] 2. This utility model enables easy disassembly and replacement of the suction pipe by setting a connecting mechanism. During installation, the two mounting blocks are aligned with the two mounting slots. After the two mounting blocks are inserted into the two mounting slots, the suction pipe is rotated 90° counterclockwise. At this time, the two mounting blocks and the two arc-shaped wedges are engaged and locked, which greatly improves the simplicity of the device and allows the staff to easily repair and replace the suction pipe.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Traditional water pumps often fail to start or frequently stall when dealing with shallow water due to insufficient suction or head, or low water levels, resulting in incomplete drainage. The following describes some embodiments of this utility model with reference to the accompanying drawings, providing a low-water-level pump.

[0016] Example 1: Combination Figures 1-5 As shown, a low-water-level pump is proposed. The pump is constructed by setting an outer shell 1 as the main body of the device. A water collection shell 3 is fixedly connected to the bottom of the outer shell 1. A support 2 is installed at the bottom of the water collection shell 3. The entire device is supported by two bases 2. A water outlet 4 is fixedly connected to the water collection shell 3. The accumulated water is easily discharged through the water outlet 4. A pump shaft 6 is installed at the top inside the outer shell 1.

[0017] To effectively remove shallow water, a vortex impeller 11 for absorbing surface water is fixedly connected to the pump shaft 6. A through hole is provided at the bottom of the water collection shell 3, and a filter plate 12 for easy filtration of impurities in the water is installed at the through hole. Multiple reamer blades 13 are installed at the bottom of the pump shaft 6. A suction pipe 5 is installed at the bottom of the water collection shell 3, and a sealing ring 7 is installed at the bottom of the suction pipe 5 to further ensure a sealed contact between the suction pipe 5 and the water. The edges of the reamer blades 13 are serrated 17. The reamer blade 13 has micro-grooves 18 on its surface. The vortex impeller 11 provides the force to draw in accumulated water. The filter plate 12 easily filters impurities, and the multiple reamer blades 13 effectively break down debris. The serrated edges 17 improve the cutting effect, and the micro-grooves 18 reduce cutting resistance. Simultaneously, the water flow impact automatically removes tangled fibrous debris. The bottom of the suction pipe 5 is kept 1-5mm from the ground, greatly reducing the blind spot and ensuring effective water extraction. Example 2: Based on Example 1, the technical solution proposed in Example 1 is used to solve the problem that traditional water pumps often fail to start or frequently jam when dealing with shallow water due to insufficient suction or insufficient head and low water level. However, the suction pipe 5 is prone to wear after long-term use. In order to facilitate easy maintenance and replacement by staff, it should be easy to disassemble and assemble.

[0018] To facilitate the easy assembly and disassembly of the suction pipe 5, combined with Figures 1-4 As shown, a connecting mechanism 16 is provided at the bottom of the water collection shell 3, and a fixing ring 1601 is fixedly connected to the bottom of the water collection shell 3. Two mounting grooves 1602 are opened at the bottom of the fixing ring 1601, and an arc-shaped groove 1603 is opened on one side of the two mounting grooves 1602. A limit block 1604 is fixedly connected to one end of the arc-shaped groove 1603 near the mounting groove 1602, and an arc-shaped wedge 1605 is fixedly connected to the top wall of the arc-shaped groove 1603. Two mounting blocks 1606 are fixedly connected to the water suction pipe 5. When water suction is required... When installing the suction pipe 5, the two mounting blocks 1606 are inserted into the two mounting slots 1602. The suction pipe 5 is rotated 90° counterclockwise. At this time, the two mounting blocks 1606 gradually lock with the two arc-shaped wedges 1605 after passing through the two limiting blocks 1604. When the suction pipe 5 needs to be disassembled, the suction pipe 5 is rotated 90° clockwise, so that the two mounting blocks 1606 slide on the two arc-shaped wedges 1605 and gradually loosen, thus being removed from the two mounting slots 1602, which improves the simplicity of the device.

[0019] Two lifting rings 14 are installed on the top of the outer casing 1. A cable 15 is connected to the outside of the outer casing 1. A rotor 9 is installed on the pump shaft 6. A stator 8 is installed outside the rotor 9. An oil chamber 10 for easy lubrication of the pump shaft 6 is installed inside the outer casing 1. The two lifting rings 14 allow the entire device to be suspended in the air. The stator 8 and rotor 9 prevent the pump shaft 6 from overheating and being damaged by idling.
