Description

Technical Field

[0001] The utility model belongs to the technical field of water pumps, and relates to a spray pump, in particular to an anti-blocking spray pump. Background Art

[0002] A spray pump, also known as a centrifugal multistage pump or a water jet thruster, is a high-performance pump device. The spray pump uses centrifugal force to transport liquid, and its core component is a centrifugal pump. The spray pump usually consists of multiple centrifugal pumps, which are connected in series to increase the water pressure. When the liquid enters the spray pump, after the continuous action of multiple centrifugal pumps, the pressure of the liquid gradually increases, and finally it is ejected in the form of high speed and high pressure.

[0003] The water inlet of the spray pump is relatively large. Usually, in order to prevent foreign objects from entering the pump body, an interception net is set at the water inlet. However, the accumulation of items at the interception net will cause the interception net to be blocked, affecting the working efficiency of the jet pump. Summary of the Invention

[0004] The purpose of the utility model is to provide an anti-blocking spray pump with large auxiliary power and large flow rate for the above problems existing in the prior art.

[0005] The purpose of the utility model can be realized by the following technical solutions: An anti-blocking spray pump, characterized in that it includes a water pump housing with a water inlet end and a water outlet end at both ends. A transmission shaft installation part is opened on the water pump housing, and a fan blade driving component is arranged in the water pump housing. A power transmission shaft is arranged on the fan blade driving component. An auxiliary water inlet structure is arranged at the water inlet end. A transmission shaft is arranged on the auxiliary water inlet structure. A plurality of spherical fan blades are arranged on the transmission shaft, and a power motor is arranged at one end of the transmission shaft. A hemispherical filter screen is also arranged at the water inlet end, and the hemispherical filter screen is in contact with the spherical fan blades.

[0006] In the above-mentioned anti-blocking spray pump, water holding cavities are opened on the spherical fan blades.

[0007] In the above-mentioned anti-blocking spray pump, a transmission bevel gear set is arranged between the power motor and the transmission shaft.

[0008] In the above-mentioned anti-blocking spray pump, a water flow guiding component is arranged at the water outlet end. A pressurized diversion housing is arranged on the water flow guiding component, and a plurality of steering rudders are arranged at the end of the pressurized diversion housing. A connecting flange is arranged between the pressurized diversion housing and the water pump housing.

[0009] In the above-mentioned anti-blocking spray pump, an installation bracket is arranged on the water pump housing.

[0010] Compared with the prior art, the anti-clogging spray pump of the present invention is provided with an auxiliary water inlet structure at the water inlet end. The spherical fan blades are driven by a motor to actively transport water liquid into the water pump housing, increasing the power performance of the jet pump by increasing the water inflow. While increasing the water inflow, the spherical fan blades also scrape off foreign matters on the surface of the hemispherical filter screen and discharge the foreign matters outside the water pump, reducing the blockage caused by foreign matters.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0014] The following are specific embodiments of the present invention in combination with the accompanying drawings to further describe the technical solutions of the present invention, but the present invention is not limited to these embodiments.

[0015] As Figure 1 , 2 shown, the anti-clogging spray pump of the present invention includes a water pump housing 1 with a water inlet end 12 and a water outlet end 7 at both ends. A drive shaft installation part 2 is provided on the water pump housing 1, and a fan blade drive assembly 13 is provided inside the water pump housing 1. A power transmission shaft 14 is provided on the fan blade drive assembly 13. An auxiliary water inlet structure 15 is provided at the water inlet end 12. A drive shaft 9 is provided on the auxiliary water inlet structure 15. A plurality of spherical fan blades 18 are provided on the drive shaft 9. One end of the drive shaft 9 is provided with a power motor 11. When the spray pump is started, the power motor 11 drives the drive shaft 9 to rotate the spherical fan blades 18 to squeeze the water source into the water inlet end 12, reducing the slow start caused by insufficient water pressure at the initial start of the spray pump. A hemispherical filter screen 16 is also provided at the water inlet end 12. The hemispherical filter screen 16 abuts against the spherical fan blades 18. When the spherical fan blades 18 rotate, they squeeze the water flow into the water pump, and at the same time, the departing fan blades contact the hemispherical filter screen 16 to discharge the impurities on the filter screen.

[0016] Preferably, water storage cavities 17 are provided on the spherical fan blades 18. While increasing the water inflow, the water storage cavities 17 can also accommodate impurities.

[0017] Preferably, a transmission bevel gear set 10 is provided between the power motor 11 and the drive shaft 9.

[0018] Preferably, a water flow guiding assembly 5 is provided at the water outlet end 7.
