Description

Technical Field

[0001] This utility model relates to the field of water pump technology, specifically to a jet spiral blade water pump. Background Technology

[0002] Traditional water pumps often suffer from problems such as poor water flow, slow water output, and low pumping efficiency during the pumping process, especially when pumping liquids containing impurities. Furthermore, the structural design of traditional water pumps is often relatively fixed, making it difficult to meet the usage requirements of different scenarios.

[0003] Therefore, developing a new type of jet helical blade water pump to improve pumping efficiency and increase operational flexibility has become an urgent problem to be solved in the field of water pump technology. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a jet helical blade water pump that uses a variable diameter turbine to increase the outlet water pressure and jet distance, thereby improving pumping efficiency and increasing the flexibility of use.

[0005] To solve the above-mentioned technical problems, the technical solution provided by this utility model is: a jet helical blade water pump, including a power input shaft, a pump body and a turbine; the end of the power input shaft is connected to the turbine, and the turbine is disposed inside the pump body;

[0006] The turbine includes a bushing and a helical blade. The bushing is fitted onto the end of the power input shaft. The thickness of the bushing gradually increases from the water inlet end to the water outlet end of the pump body. The helical blade extends axially along the outer wall of the bushing, and the distance between its edge and the inner wall of the pump body gradually decreases from the water inlet end to the water outlet end of the pump body.

[0007] Furthermore, the pump body includes an inlet pipe, a pump body, and an outlet pipe. The inlet pipe is connected to the inlet end of the pump body, the outlet pipe is connected to the outlet end of the pump body, and the turbine is located inside the pump body.

[0008] Furthermore, the inlet pipe, pump body, and outlet pipe are on the same straight line, and the inlet pipe is sleeved outside the power input shaft, with several inlet holes provided on the wall of the inlet pipe.

[0009] Furthermore, the water inlet pipe is sleeved outside the power input shaft and is a bent pipe. The water outlet of the water inlet pipe is on the same straight line as the pump body and the water outlet pipe, and the water inlet of the water inlet pipe is bent to one side.

[0010] Furthermore, the water outlet pipe is sleeved outside the power input shaft and is a bent pipe. The water inlet of the water outlet pipe is on the same straight line as the pump body and the water inlet pipe, and the water outlet of the water outlet pipe is bent to one side.

[0011] Furthermore, the pump body is provided with support legs at the bottom.

[0012] Furthermore, a drive connector is provided on the power input shaft.

[0013] Furthermore, the power input shaft is connected to a motor.

[0014] Furthermore, both the inlet and outlet pipes are equipped with pipe joints at their ends.

[0015] The advantages of this invention compared to existing technologies are as follows: The jet pump of this invention adopts a specially designed turbine structure. The thickness of the bushing gradually increases from the water inlet end to the water outlet end of the pump body, while the spiral blades extend axially along the outer wall of the bushing, and the distance between their edges and the inner wall of the pump body gradually decreases. This design allows the water flow to receive a stronger driving force when passing through the turbine, thereby increasing the distance the water is ejected and significantly improving pumping efficiency.

[0016] The pump body of this invention includes an inlet pipe, a pump body, and an outlet pipe, and these components can be flexibly combined. The inlet and outlet pipes can be designed as straight lines or as bent pipes to adapt to the usage requirements of different scenarios. This flexibility enables the water pump of this invention to be widely used in various complex environments. Attached Figure Description

The helical blades 5 extend axially along the outer wall of the bushing 4, and the distance between their edges and the inner wall of the pump body 2 gradually decreases from the water inlet end to the water outlet end of the pump body 2.

For example, the inlet pipe 6, pump body 7, and outlet pipe 8 can be on the same straight line, with the inlet pipe 6 sleeved outside the power input shaft 1. The inlet pipe 6 has several inlet holes 13 on its wall to facilitate water flow into the pump body 2. Furthermore, the inlet pipe 6 and outlet pipe 8 can be designed as bent pipes to adapt to different usage scenarios. When the inlet pipe 6 is a bent pipe, its outlet is on the same straight line as the pump body 7 and outlet pipe 8, with the inlet bent to one side for easy side water intake. When the outlet pipe 8 is a bent pipe, its inlet is on the same straight line as the pump body 7 and inlet pipe 6, with the outlet bent to one side for easy side drainage.

[0037] To increase the stability of the water pump, a support leg 9 is provided at the bottom of the pump body 7.
