Description

Technical Field

[0001] The utility model belongs to the technical field of water pumps, and particularly relates to a water pump structure with a diversion structure. Background Art

[0002] A water pump is a machine that transports liquids or increases the pressure of liquids. The water pump converts the mechanical energy or other energy of the prime mover into the energy of the liquid. The classification of water pumps is extensive, but basically, the transportation of water flow is controlled by the centrifugal force of the impeller. When the existing water pump is in use, the impact force generated by the water flow will hit the inner wall of the water pump, reducing the water flow velocity and generating noise.

[0003] According to the search, the patent document with the publication number CN219262772U discloses a diversion structure of a water pump, which includes a pump body and an impeller installed in the pump body. The pump body has a water inlet and a water outlet. The characteristic is that the pump body has a water inlet cavity communicated with the water inlet and a water outlet cavity communicated with the water outlet. The impeller is located in the water inlet cavity, and the water outlet cavity surrounds the circumferential outer side of the water inlet cavity. The diversion structure includes an annular diversion disk, and the diversion disk is fixed in the water outlet cavity or the diversion disk is fixed between the water inlet cavity and the water outlet cavity. A plurality of diversion holes are spaced in the diversion disk. The diversion holes are circular. A first strengthening ring is provided at the edge of the diversion hole. A second strengthening ring is provided on the inner side wall of the diversion disk. A third strengthening ring is provided on the outer side wall of the diversion disk. The first strengthening ring is fixedly connected with both the second strengthening ring and the third strengthening ring.

[0004] When the existing water pump with a diversion structure is in use, there are the following deficiencies: when the existing device conducts diversion transformation on the water pump, the diversion operation is mainly carried out through a porous diversion disk. However, in the normal use environment of the water pump, the impact force of the water flow in the high water pressure environment is relatively large. When passing through the diversion disk, it will impact the disk surface of the diversion disk, and the water flow velocity will drop rapidly. The efficiency of the diversion holes on the diversion disk for diverting and guiding the water flow is too low. Summary of the Utility Model

[0005] In order to achieve the above object, the utility model adopts the following technical scheme:

[0006] A water pump structure with a diversion structure includes a diversion outer shell. A diversion mechanism is arranged inside the diversion outer shell. A connection port is arranged on one side of the diversion outer shell. A main pump body is communicated and arranged on the side of the connection port away from the diversion outer shell. A water outlet is arranged at the top of the main pump body;

[0007] A driving motor is arranged on one side of the main pump body, and the output end of the driving motor is connected to the main pump body.

[0008] Preferably, the diversion mechanism includes a water inlet and an arc-shaped diversion block. The three water inlets are arranged on the side surface of the diversion housing, and the three arc-shaped diversion blocks are fixedly connected inside the diversion housing.

[0009] Preferably, three rotating diversion plates are rotatably connected inside the diversion housing, and arc-shaped limiting grooves are formed in the diversion housing corresponding to the positions of the rotating diversion plates.

[0010] Preferably, an adjusting clamping shaft is coaxially and fixedly connected to the rotating diversion plate, and the adjusting clamping shaft is slidably connected in the arc-shaped limiting groove on the corresponding side.

[0011] Preferably, a protective housing is arranged on one side of the diversion housing. The connection port penetrates through the protective housing, and the arc-shaped limiting groove penetrates through the protective housing.

[0012] Preferably, three fixing seats are arranged inside the protective housing. A cylindrical tension spring is arranged on the fixing seat, and the output end of the cylindrical tension spring is movably connected to the adjusting clamping shaft on the corresponding side.

[0013] Compared with the prior art, the present utility model has the following advantages:

[0014] By setting the diversion mechanism, multiple water inlets are set, and water flow is introduced into the diversion housing from different angles. Since the water flow direction will deflect to a certain extent when passing through the arc-shaped diversion block, and at the same time, the rotating diversion plate will deflect to a certain extent under the action of the cylindrical tension spring. When contacting the water flow, it will deform to a certain extent, buffering the water flow to a certain extent and ensuring the flow direction of the water flow. When the three water flows flow towards the connection port, a vortex will be formed. In this way, the water flow decelerated by the rotating diversion plate can be accelerated again, and it is evenly distributed on the impeller in the main pump body, which not only ensures the normal working efficiency of the water pump but also avoids the noise and vibration caused by the kinetic energy of the water flow.

Detailed implementation manner

[0020] The technical solutions in the present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0021] Refer to Figures 1-4 , a water pump structure with a diversion structure, including.

[0022] The diversion housing 1 is provided with a diversion mechanism inside. A connection port 2 is arranged on one side of the diversion housing 1. A main pump body 3 is communicated and arranged on the side of the connection port 2 away from the diversion housing 1. A water outlet 4 is arranged on the top of the main pump body 3;

[0023] A drive motor 5 is arranged on one side of the main pump body 3. The output end of the drive motor 5 is connected to the main pump body 3. The drive motor 5, as the prime mover of the main pump body 3, can provide power for the main pump body 3;

[0024] The diversion mechanism includes a water inlet 6 and an arc-shaped diversion block 7. Three water inlets 6 are arranged on the side surface of the diversion housing 1. Three arc-shaped diversion blocks 7 are fixedly connected inside the diversion housing 1. Three rotating diversion plates 8 are rotatably connected inside the diversion housing 1. Arc-shaped limiting grooves 13 are opened at the positions corresponding to the rotating diversion plates 8 inside the diversion housing 1. An adjustment clamping shaft 9 is coaxially and fixedly connected to the rotating diversion plate 8. The adjustment clamping shaft 9 is slidably connected in the arc-shaped limiting groove 13 on the corresponding side. A protective housing 10 is arranged on one side of the diversion housing 1. The connection port 2 penetrates through the protective housing 10. The arc-shaped limiting groove 13 penetrates through the protective housing 10. Three fixed seats 11 are arranged inside the protective housing 10. A cylindrical tension spring 12 is arranged on the fixed seat 11. The output end of the cylindrical tension spring 12 is movably connected to the adjustment clamping shaft 9 on the corresponding side. By arranging a plurality of water inlets 6, water flow can be introduced into the diversion housing 1 from different angles. Since the water flow direction will deflect to a certain extent when the water flow passes through the arc-shaped diversion block 7, and at the same time due to the impact of the water flow, the cylindrical tension spring 12 is stretched, and the rotating diversion plate 8 will deflect to a certain extent under the action of the cylindrical tension spring 12. This buffers the water flow to a certain extent and at the same time ensures the flow direction of the water flow. When the three water flows flow towards the connection port 2, a vortex will be formed. In this way, the water flow decelerated by the rotating diversion plate 8 can be accelerated again, and it is evenly distributed on the impeller in the main pump body 3. In this way, both the normal working efficiency of the water pump is ensured, and the noise and vibration caused by the kinetic energy of the water flow are avoided.

[0025] The functional principle of the present invention can be described by the following operation method:

[0026] A driving motor 5 is arranged on one side of the main pump body 3. The output end of the driving motor 5 is connected to the main pump body 3. As the prime mover of the main pump body 3, the driving motor 5 can provide power for the main pump body 3.

[0027] Through a plurality of water inlets 6 provided, water flow can be introduced into the diversion outer shell 1 from different angles. Since the water flow direction will deflect to a certain extent when passing through the arc-shaped diversion block 7, and at the same time due to the impact of the water flow, the cylindrical tension spring 12 is stretched. The rotating diversion plate 8 will deflect to a certain extent under the action of the cylindrical tension spring 12, which buffers the water flow to a certain extent and at the same time ensures the flow direction of the water flow. When three water flows flow towards the connection port 2, a vortex will be formed. In this way, the water flow decelerated by the rotating diversion plate 8 can be accelerated again, and it is evenly distributed on the impeller in the main pump body 3. This not only ensures the normal working efficiency of the water pump, but also avoids the noise and vibration caused by the kinetic energy of the water flow.
