[0002] The new submersible axial flow pump is a high-efficiency underwater drainage device suitable for high flow and low head applications. Its motor and pump body are integrated into a compact structure, which is easy to install and can be submerged for a long time. It is widely used in urban flood control, farmland irrigation, industrial circulating water and river management, and features stable operation and easy maintenance.

[0003] Most new submersible axial flow pumps on the market do not have a shock absorption mechanism. When the axial flow pump is dropped into a well or sewer, the upward impact of the water pressure can easily loosen the parts of the new submersible axial flow pump. If it touches the bottom surface, it can be damaged due to excessive vibration. Therefore, improvements are needed.

[0004] Based on this, this utility model designs a novel submersible axial flow pump to solve the above problems. Utility Model Content

Therefore, a new submersible axial flow pump is proposed.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A novel submersible axial flow pump includes a main body. A mounting cavity is fixedly installed at the bottom of the main body. A pressure-bearing cavity is fixedly installed at the bottom of the mounting cavity. A rubber sleeve is fitted onto the outer side of the pressure-bearing cavity. A mounting ring is fitted onto the outer side of the rubber sleeve. Multiple buffer grooves are formed inside the mounting ring. Multiple damping blocks are fixedly installed at the top of the mounting ring, with the positions of the damping blocks corresponding to the positions of the buffer grooves. A support carrier is fitted onto the outer side of the rubber sleeve corresponding to the bottom of the mounting ring. Multiple support columns are fixedly installed at the top of the support carrier, with the positions of the support columns passing through the buffer grooves and corresponding to the positions of the damping blocks. A buffer spring is provided on the surface of the support column. Multiple telescopic support rods are fixedly installed at the bottom of the support carrier. A support sleeve is provided at the bottom of the telescopic support rod, and a telescopic groove is formed inside the support sleeve.

[0018] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0019] 1. In this utility model, by setting damping blocks and support columns, when the new submersible axial flow pump is working, the lifting device is first connected to the lifting lug, and the new submersible axial flow pump is lifted and placed in the designated position. When the support sleeve column at the bottom of the new submersible axial flow pump touches the bottom of the water flow, the upward impact force drives multiple support columns to move upward inside the buffer groove. The support columns rub against the damping block and compress the buffer spring to deform, so as to buffer the impact of the new submersible axial flow pump after it enters the water and touches the ground.

[0020] 2. In this utility model, by setting an impeller and a guide cone, when the new submersible axial flow pump is placed in the designated working water area, the oil-filled submersible motor is started, which drives the output shaft at one end of the oil-filled submersible motor to start rotating. The output shaft drives the impeller at the bottom to rotate. The guide cone installed at the bottom of the impeller guides the water flow to enter the impeller smoothly, avoiding the generation of vortices or turbulence at the inlet, reducing hydraulic loss. The guide cone can reduce water surface vortices, prevent air from entering the pump, and reduce the risk of cavitation. Attached Figure Description

[0029] The specific implementation method is as follows: a connecting welding plate 14 is fixedly installed on the top of the mounting cavity 2, and the mounting cavity 2 is connected to the device body 1 through the connecting welding plate 14. Multiple mounting holes 15 are opened inside the connecting welding plate 14, screws 16 are installed inside the mounting holes 15, and nuts 17 are rotatably installed on the top of the screws 16.

[0030] By setting the connecting welding plate 14 and the mounting hole 15, the lifting device on the top of the device body 1 is aligned with the connecting welding plate 14, and multiple screws 16 are placed inside the mounting hole 15. The screws 16 are then installed on the surface of the mounting hole 15 to fix the device body 1 and other parts together.

[0031] The specific implementation method is as follows: multiple mounting posts 18 are fixedly installed inside the mounting cavity 2, a waterproof placement box 19 is fixedly installed at one end of the mounting post 18, and an oil-filled submersible motor 20 is fixedly installed inside the waterproof placement box 19.

[0032] By setting up a waterproof housing box 19 and an oil-filled submersible motor 20, after the new submersible axial flow pump is placed in the working water area, the waterproof housing box 19 and the sealing collar at the bottom of the waterproof housing box 19 ensure that the oil-filled submersible motor 20 inside will not be soaked in water, so as to avoid affecting the operation.

[0033] The specific implementation method is as follows: an output shaft 21 is rotatably mounted on the bottom of the oil-filled submersible motor 20, and a sealing ring is sleeved on the top of the output shaft 21. An impeller 22 is rotatably mounted on the bottom of the output shaft 21, and a guide cone 23 is provided at the bottom of the impeller 22.

[0039] Working principle and usage: First, transport the new submersible axial flow pump to the designated working position. Then, fix the lifting device and the lifting lug 27 on the top of the connecting column 26. Place the new submersible axial flow pump in the designated working water area. After the multiple support sleeves 12 at the bottom of the new submersible axial flow pump touch the ground, the upward impact force causes the telescopic support rod 11 to retract inside the support sleeve 12, and drives multiple support columns 9 to move inside the buffer groove 6. The impact force is buffered by friction through the inside of the damping block 7. Then, start the oil-filled submersible motor 20 to drive the bottom output shaft 21 to rotate. The output shaft 21 drives the impeller 22 to rotate to draw water. The guide cone 23 set at the bottom of the impeller 22 optimizes the water flow state and improves the pump's operating efficiency and stability. The water in the suction channel is discharged through the connecting column 26 on one side of the main body 1 to complete the pumping work.
