Detailed Description

The technical solutions of the present application will be described in detail below with reference to the accompanying drawings in combination with embodiments.

In order to more quickly and efficiently complete water pumping operation in the water conservancy construction process, the application provides a water pumping device. The pumping device comprises a pumping barrel 10, wherein two ends of the pumping barrel 10 are respectively provided with a water inlet 101 and a water outlet 102; a rotation shaft 20, the rotation shaft 20 is coaxially disposed in the pumping barrel 10, and an impeller assembly 30 is disposed on the rotation shaft 20. When the power source provides power for the pumping device, the rotating shaft 20 rotates to drive the impeller assembly 30 to rotate, the water flow is sucked from the water inlet 101 by virtue of the lifting force generated by the water flow when the impeller assembly 30 rotates, the water flow moves axially along the pumping barrel 10, and finally, the water is discharged through the water outlet 102, so that the whole pumping and draining process is completed.

In the process of water pumping and draining, in order to prevent water grass, fish and other sundries in water from entering the water pumping barrel 10 through the water inlet 101 to cause the blockage of the impeller assembly 30, a filter screen 103 which can effectively play a role in filtering can be arranged at the water inlet 101; specifically, the filter screen 103 and the water inlet 101 may be connected by bolts. In addition, a connecting ring can be arranged at the water outlet 102 according to the requirement, and the connecting ring is connected with an external pipeline, so that the water outlet distance of the water outlet 102 is increased, and the working radius of the water pumping device is increased.

The external structure of the pumping cartridge 10 may be provided in various forms, such as square cartridges, as needed, in order to ensure that the water flow more smoothly moves within the pumping cartridge 10, and thus, at least a portion or all of the pumping cartridge 10 is provided in a cylindrical shape.

The horizontal or longitudinal movement of the rotation shaft 20 disposed in the pumping barrel 10 may occur during the rotation process, thereby affecting the rotation shaft 20 to more sufficiently transmit the power provided by the power source to the impeller assembly 30, in order to prevent such a situation, to ensure that the rotation shaft 20 can rotate more stably and reliably, a support structure may be disposed in the pumping barrel 10 to rotatably support the rotation shaft 20; that is, the supporting structure can rotate along with the rotating shaft 20, and simultaneously can support and fix the rotating shaft 20 to prevent the rotating shaft from moving horizontally or longitudinally during the rotation process.

The support structure may be arranged in various ways, for example, the support structure may be arranged as a fixing ring for supporting and reinforcing the rotation shaft 20, or the support structure may be directly arranged as a bearing between the inner wall of the water pumping barrel 10 and the rotation shaft 20 for supporting and reducing friction; preferably, the support structure may be designed as one or more support walls 11 provided on the inner wall of the pump cartridge 10, the shaft 20 being capable of extending through the support walls 11 and providing bearings between the support walls 11 and the shaft 20; therefore, the supporting effect of the supporting wall 11 on the rotating shaft 20 can be fully exerted, the friction coefficient generated between the supporting wall 11 and the rotating shaft 20 in the rotating process can be effectively reduced, and the rotating precision of the rotating shaft 20 is ensured.

The rotating shaft 20 is used as a core component of the pumping device, and in order to distinguish different functions played by two ends of the rotating shaft 20, two ends of the rotating shaft 20 can be divided into a working end 201 and a driving end 202; wherein the impeller assembly 30 is detachably mounted to the working end 201 of the shaft 20; and the other end of the rotating shaft 20 is connected with a driving end 202 in a driving way.

Further, while the impeller assembly 30 is disposed at the working end 201 of the rotating shaft 20, the impeller assembly 30 may be disposed adjacent to the water inlet 101 in order to more fully exert the lift force generated on the water flow when the impeller assembly 30 rotates; meanwhile, in order to make the water flow more smoothly in the pumping cartridge 10, the driving end 202 of the rotation shaft 20 coaxially disposed in the pumping cartridge 10 may be disposed outside the pumping cartridge 10.

The drive end 202 of the shaft 20 may be in a variety of forms in driving connection with the power source, preferably the drive end 202 may be configured to be in driving connection with an engine or motor via a belt drive; for example, the driving end 202 may be configured as a driving wheel in threaded connection with the rotating shaft 20, where the driving wheel is in driving connection with the engine or the motor through a belt, and receives the power output by the engine or the motor to rotate, so as to drive the rotating shaft 20 to rotate.

The impeller assembly 30 disposed at the working end 201 of the shaft 20 may be designed in various forms as required, and the impeller assembly 30 may be configured to include at least one impeller in order to ensure that the impeller assembly 30 can effectively exert a lift force on a water flow generated when the impeller assembly rotates. The impeller has a similar function to that of the impeller in the axial flow pump, namely, energy provided by a power source is transmitted to water flow through the action of centrifugal force, the water flow is firstly sucked into the water pumping barrel 10 at the water inlet 101, the water flow maintains a certain water speed and pressure in the water pumping barrel 10, and finally, the water flow is fed and discharged through the water outlet 102.

In order to ensure that the impeller assembly 30 can fully exert the lift force generated by the water flow during the rotation of the impeller assembly 30, and simultaneously to enable the water flow to flow in the water pumping barrel 10 more smoothly, the impeller assembly 30 can be provided with a first impeller 301 and a second impeller 302 which are fixedly arranged on the rotating shaft 20; wherein the first impeller 301 is closer to the end of the shaft 20 than the second impeller 302. Here, the first impeller 301 functions similarly to the previously described impeller, while the second impeller 302 functions similarly to the vanes in an axial flow pump, i.e. the flow of water coming out of the first impeller 301 is converted from a rotational movement into an axial movement, while at the same time part of the kinetic energy of the flow is converted into pressure potential energy. That is, by arranging the first impeller 301 and the second impeller 302 on the rotating shaft 20, the water pumping device can effectively ensure that water flow can be forcefully sucked into the water pumping barrel 10 from the water inlet 101, and simultaneously ensure that the sucked water flow can smoothly flow in the water pumping barrel 10 and finally be discharged out through the water outlet 102.

Still further, in order to ensure that the water flow sucked from the water inlet 101 by the first impeller 301 can be changed from the rotational movement to the axial movement more sufficiently so that the water flow can flow in the pumping barrel 10 more smoothly, the number of blades of the first impeller 301 may be set to be smaller than that of the second impeller 302 or the inclination angle of the blades of the first impeller 301 may be set to be larger than that of the second impeller 302; or the inclination angle of the blades of the first impeller 301 is set larger than that of the blades of the second impeller 302 on the basis that the number of the blades of the first impeller 301 is set smaller than that of the blades of the second impeller 302.

Of course, the power source may be provided as part of the pumping device according to construction requirements, and the power source may be provided at a position connected to the driving end 202, which may be inside the pumping barrel 10 or outside the pumping barrel 10. In addition, for the external power source, an adjusting bracket can be optionally arranged at a proper position outside the water pumping barrel 10, so as to adjust the relative position of the driving end 202 when in driving connection with the external power source.

The following is a schematic structural diagram of a pumping device according to an embodiment of the present application shown in fig. 1, and specifically explains the working process of the pumping device:

The working process of the water pumping device is explained below:

the water pumping device is placed at a proper position in a region where water pumping operation is required, the water outlet 101 with the filter screen 103 and the first impeller 301 are immersed in water, an external power source is started, power output by the power source is transmitted to the rotating shaft 20 which is arranged inside the water pumping barrel 10 and is coaxial with the water pumping barrel 10 through the transmission end 202, the rotating shaft 20 can reliably rotate under the support of the supporting wall 11 arranged on the inner wall of the water pumping barrel 10, the first impeller 301 and the second impeller 302 of the impeller assembly 30 arranged at the working end 201 are driven to rotate, water flow can be filtered by the filter screen 103 and then sucked into the water pumping barrel 10 through the water inlet 101 by the rotation of the first impeller 301, then the water flow flowing out of the first impeller 301 is converted into axial motion by the second impeller 302, and meanwhile, part of kinetic energy of the water flow is converted into pressure potential energy, so that the water flow sucked by the first impeller 301 can smoothly flow in the water pumping barrel 10 and is discharged through the water outlet 102.
