Description

Technical Field

[0001] The present invention relates to a water pump device, in particular to an active pressurizing water pump, belonging to the technical field of water pump devices. Background Art

[0002] A water pump is a machine that transports liquids or pressurizes liquids. It transmits the mechanical energy of the prime mover or other external energy to the liquid, increasing the energy of the liquid. It is mainly used to transport liquids including water, oil, acid-base solutions, emulsions, suspension liquids, and liquid metals, etc. A water pump can also transport liquid-gas mixtures and liquids containing suspended solids. The technical parameters of the performance of a water pump include flow rate, suction lift, head, shaft power, water power, efficiency, etc.; most common water pumps are vane pumps. Vane pumps use the interaction between rotating vanes and water to transfer energy, and there are types such as centrifugal pumps, axial flow pumps, and mixed flow pumps.

[0003] Centrifugal pump: Before starting the water pump, first fill the pump and the inlet pipe with water. After the water pump starts running, under the action of the centrifugal force generated by the high-speed rotation of the impeller, the water in the impeller passage is thrown to the surroundings and pressed into the volute. A vacuum is formed at the impeller inlet, and the water in the water tank is sucked in along the suction pipe under the action of the external atmospheric pressure to supplement this space. Subsequently, the sucked water is thrown out by the impeller and enters the outlet pipe through the volute. Thus, it can be seen that if the impeller of the centrifugal pump rotates continuously, it can continuously suck and press water, and the water can be continuously lifted from a low place to a high place or a far place. To sum up, a centrifugal pump lifts water to a high place under the action of the centrifugal force generated by the high-speed rotation of the impeller, so it is called a centrifugal pump. The flow direction of water along the centrifugal pump is sucked in axially along the impeller and flows out perpendicular to the axis, that is, the inlet and outlet water flow directions are mutually at 90°. Since a centrifugal pump sucks water by forming a vacuum at the impeller inlet, it is necessary to fill the pump and the suction pipe with priming water before starting, or use a vacuum pump to evacuate the air to form a vacuum. Moreover, the pump casing and the suction pipe must be strictly sealed and not leak air, otherwise a vacuum cannot be formed and water cannot be sucked up. Since an absolute vacuum cannot be formed at the impeller inlet, the suction height of a centrifugal pump cannot exceed 10 meters. Coupled with the frictional loss along the suction pipe during the water flow, the actual allowable installation height (the height of the water pump axis from the water surface of the suction) is much less than 10 meters. If the installation height is too high, water cannot be sucked; in addition, since the atmospheric pressure in mountainous areas is lower than that in plains, when installing the same water pump in mountainous areas, especially in high mountainous areas, its installation height should be reduced, otherwise water cannot be sucked up either.

[0004] Axial flow pump: The working principle of an axial flow pump is different from that of a centrifugal pump. It mainly uses the thrust generated by the high-speed rotation of the impeller to lift water. When the blades of the axial flow pump rotate, the lift force generated on the water can push the water from below to above. The blades of the axial flow pump are generally immersed in the water pool of the water source to be sucked. Due to the high-speed rotation of the impeller, under the action of the lift force generated by the blades, the water is continuously pushed upward, causing the water to flow out along the outlet pipe. As the impeller rotates continuously, the water is continuously pressed to a high place. The water flow direction in the axial flow pump is to be sucked axially along the impeller and flow out axially, so it is called an axial flow pump. It has a low head (1 - 13 meters), a large flow rate, and high efficiency, and is suitable for drainage and irrigation in plains, lake areas, and river areas. It does not need to be filled with water before starting, and the operation is simple.

[0005] Mixed flow pump: Since the impeller shape of the mixed flow pump is between that of the centrifugal pump impeller and the axial flow pump impeller, therefore, the working principle of the mixed flow pump has both centrifugal force and lift force. Relying on the combined action of the two, the water flows out of the impeller at an angle to the axis, and the water is lifted to a high place through the volute chamber and the pipeline. Compared with the centrifugal pump, the mixed flow pump has a lower head and a larger flow rate. Compared with the axial flow pump, it has a higher head and a lower flow rate. It is suitable for drainage and irrigation in plains and lake areas. The water flow direction in the mixed flow pump is to be sucked and flow out at an angle to the impeller axis, so it is also called an inclined flow pump.

[0006] In summary, the water pumps in the prior art generally have the problems of high head and low flow rate or high flow rate and low head, and it is impossible to achieve double high efficiency of head and flow rate, which greatly limits the popularization and application of the existing water pumps. Summary of the Invention

[0007] Aiming at the defect that the water pumps in the prior art generally cannot have both high head and large flow rate, the present invention provides an active supercharging water pump. This active supercharging water pump can improve the head of the water pump while ensuring a high flow rate of the water pump. Through the special structural design of the active water pressure rotor and the active water pressure pipeline, and under their synergistic action, the energy conversion efficiency is greatly improved, providing a new technical approach for the popularization and application of the water pump.

[0008] To achieve the above object, the technical solutions adopted by the present invention are described as follows:

[0009] An active pressure-boosting water pump comprises a water pump body, an active pressure-water rotor, an active pressure-water pipeline, and a drive device. The water pump body is a box-type structure having a cavity, the internal cavity of which is divided into a water inlet cavity and a water outlet cavity by a partition wall. A connecting pipe connecting the water inlet cavity and the water outlet cavity is provided on the partition wall. The active pressure-water rotor is installed in the connecting pipe and is located at the water inlet end of the connecting pipe. The active pressure-water pipeline is a spiral pipe extending along the axial direction of the active pressure-water rotor and coiled around the outer circumference of the active pressure-water rotor, and the inner wall of the water inlet end of the connecting pipe is wrapped around the outermost side of the active pressure-water pipeline. One end of the active pressure-water pipeline facing the water inlet cavity is a pressure-water inlet, and the other end is a pressure-water outlet. The drive device is arranged outside the water pump body, and its rotating shaft passes through the water outlet cavity, the active pressure-water rotor, and the water inlet cavity in sequence from one end of the water pump body, and the rotating shaft is connected to the active pressure-water rotor by transmission. The water pump body is provided with a water inlet pipe opening and a water outlet pipe opening.

[0010] Preferably, the active booster water pump further includes a boost mechanism. The boost mechanism is a variable-diameter pipe structure, with the larger end connected to the water outlet of the connecting pipe. A rotating shaft of the drive device extends from the smaller end of the boost mechanism and out of the larger end, forming a boost channel between the rotating shaft and the inner wall of the boost mechanism.

[0011] Preferably, the maximum diameter of the boosting mechanism is smaller than the diameter of the water outlet of the connecting pipe, and the end of the boosting mechanism with the larger diameter extends into the connecting pipe and is slidably connected to the connecting pipe via a bearing. The inner wall of the boosting mechanism is fixedly connected to the rotating shaft via a plurality of spiral guide plates evenly distributed along the circumference of the boosting channel.

[0012] Preferably, the active boost water pump further comprises a water inlet guide structure. The water inlet guide structure is arranged at the water inlet end of the active water pressure rotor. The water inlet guide structure comprises a guide structure main body and a transverse guide outer ring. The transverse guide outer ring is arranged on the outer periphery of the water outlet end of the guide structure main body, so that the transverse guide outer ring surrounds the outer periphery of the rotating body formed by the rotation of the water pressure inlet of the active water pressure pipeline. The water outlet end of the transverse guide outer ring is connected to the water inlet end of the connecting pipe. Preferably, a guide plate is provided on the transverse guide outer ring.

[0013] Preferably, the water inlet guide structure further includes a transverse guide inner ring. The transverse guide inner ring is fixedly connected to the water outlet end of the guide structure body and forms a concentric circle with the transverse guide outer ring, such that the transverse guide inner ring surrounds the inner side of a rotating body formed by the rotation of the pressure water inlet of the active pressure water pipeline. Preferably, a guide plate is provided on the transverse guide inner ring.

[0014] Preferably, the water inlet guiding structure further includes a vertically arranged guiding structure. The vertically arranged guiding structure is arranged inside the water outlet end of the guiding structure main body. And the vertically arranged guiding structure is located upstream of the water inlet of the active water pressure pipeline. Preferably, the vertically arranged guiding structure is provided with a diversion plate. The diversion plate on the vertically arranged guiding structure is a curved structure or an inclined structure. Further preferably, the bending direction or the inclined direction of the diversion plate on the vertically arranged guiding structure is the same as the spiral direction of the active water pressure pipeline.

[0015] Preferably, the number of the plurality of active water pressure pipelines is 2 - 1000, preferably 4 - 500, and more preferably 8 - 200. Preferably, the plurality of active water pressure pipelines are grouped and arranged in a spiral shape around the outside of the active water pressure rotor. The water inlets of the active water pressure pipelines in each group are arranged from the inside to the outside along the diameter direction of the active water pressure rotor. Preferably, multiple groups of active water pressure pipelines are arranged in multiple circles in sequence from the inside to the outside around the outside of the active water pressure rotor.

[0016] Preferably, the opening of the water inlet of the active water pressure pipeline faces the rotation direction of the active water pressure rotor. Along the rotation direction of the active water pressure rotor, between the water inlets of any two adjacent active water pressure pipelines, the top wall of the water inlet of the previous active water pressure pipeline extends backward and obliquely and is connected to the bottom wall of the water inlet of the next active water pressure pipeline. That is to say, the water inlets of the plurality of active water pressure pipelines distributed in a circular shape are integrally arranged in a zigzag shape. Preferably, the active water pressure pipeline is a reduced-diameter pipeline.

[0017] Preferably, the water inlet is opened on the top wall of the water inlet cavity, and the water outlet is opened on the top wall of the water outlet cavity. The side walls at the end of the water inlet cavity away from the water outlet cavity and the side walls at the end of the water outlet cavity away from the water inlet cavity are both detachable sealing end covers. Both of the two sealing end covers are movably connected to the rotating shaft through sealing bearings. Preferably, sewage discharge holes are opened at the bottoms of the side walls of the water inlet cavity and the water outlet cavity.

[0018] Preferably, a fixing seat is further arranged at the bottom of the water pump main body. Fixing holes are opened on the fixing seat. Preferably, an anti-slip mechanism is further arranged on the bottom surface of the fixing seat. Preferably, the anti-slip structure is a strip-shaped or block-shaped protrusion.

[0019] In the prior art, existing vane pumps mainly utilize the interaction between rotating vanes and water to transfer energy, thereby achieving the propulsion and lifting of water. However, the energy conversion efficiency of existing vane pumps is low. Generally, in order to obtain a high head, the water flow rate must be reduced because, based on the limited energy conversion efficiency of the vanes, the energy that can be transferred is relatively small, and it can only meet the requirements of a small amount of water flow to achieve a high head. Therefore, in the prior art, only by reducing the water flow rate can the limited external energy act on a small amount of water, thereby achieving the purpose of increasing the head. Conversely, in order to obtain a higher water flow rate, the limited energy needs to be transferred to a larger amount of water body, which will inevitably result in a not-so-high head of the pumped water. That is to say, due to the low energy conversion efficiency of the vane pumps in the prior art, it is impossible to well balance high head and high water flow rate, which greatly limits the application and development of vane pumps.

[0020] In the present invention, the active water-pressing pipeline is spirally arranged around the active water-pressing rotor, and the active water-pressing rotor is arranged at the water inlet end of the connecting pipe. One end of the active water-pressing pipeline far from the water outlet of the connecting pipe is the water inlet. The active water-pressing rotor rotates driven by a driving device. The active water-pressing rotates, driving the active water-pressing pipeline to rotate. The active water-pressing pipeline is spirally coiled around the active water-pressing rotor. When the active water-pressing rotor rotates, the water inlet of the active water-pressing pipeline faces the direction of rotation of the active water-pressing rotor. Under the action of the active water-pressing pipeline, the water at the water inlet enters the water outlet cavity communicated with the connecting pipe along the active water-pressing pipeline. As the active water-pressing rotor rotates, a large amount of water enters the water outlet cavity and forms a high-static-pressure water body, that is, a high-pressure water body, in the water outlet cavity, and finally sprays out from the water outlet pipe. Compared with the prior art, the spiral arrangement of the active water-pressing pipeline greatly improves the energy conversion efficiency, can actively increase the water flow, increases the water flow pressure and velocity, and ensures a high head while also ensuring a relatively high water flow rate.

[0021] It should be noted that both ends of the active water-pressing rotor are shafts, and the middle part is the installation part of the active water-pressing pipeline. The middle part of the active water-pressing rotor protrudes outward. The active water-pressing pipeline is spirally arranged outside the middle part of the active water-pressing rotor. The water inlet of the active water-pressing pipeline faces the tangential direction of the rotation of the active water-pressing rotor. The orientation of the water inlet of the active water-pressing pipeline can also be within a range of 180 degrees from the tangential direction of the rotation of the active water-pressing rotor.

[0022] In the present invention, a pressurization mechanism is further provided at the water outlet of the connecting pipe, and the pressurization mechanism is a variable-diameter pipe structure with a gradually decreasing diameter according to the water flow direction. The water body actively pressurized by the active water pressure pipe enters the pressurization structure, and multiple rotating high-pressure water flows are mixed in the pipe cavity of the pressurization structure to achieve further pressurization, thereby further increasing the pressure of the water body entering the water outlet cavity. At the same time, it can also prevent the multiple high-pressure water flows moving in a spiral manner from directly entering the water outlet cavity to cause disturbance and consume internal energy. Further, a guide vane spirally extending along the water flow direction is provided in the pipe cavity of the pressurization mechanism, which promotes the confluence of multiple high-pressure water flows and can reduce the internal energy consumption.

[0023] In the present invention, the water inlet guiding structure is arranged in front of (the water inlet end) the active water pressure rotor and covers the head of the active water pressure rotor. The water inlet guiding structure and the connecting pipe cover the active water pressure rotor inside. The water inlet guiding structure is provided with a horizontally arranged guiding outer ring around the rotating body formed by the rotation of the water inlet of the active water pressure pipe, and the horizontally arranged guiding outer ring is used to guide the water body entering the active water pressure device from the radially outer side. The rotational water resistance of the active water pressure rotor is reduced.

[0024] Further, the water inlet guiding structure is also provided with a horizontally arranged guiding inner ring in the inner ring of the rotating body formed by the rotation of the water inlet of the active water pressure pipe. The horizontally arranged guiding inner ring is used to guide the water body entering the active water pressure device from the radially inner side. The rotational water resistance of the active water pressure rotor is reduced.

[0025] It should be noted that guide plates are provided on the horizontally arranged guiding outer ring, the horizontally arranged guiding inner ring, and the vertically arranged guiding structure. The direction of the guide plates is the same as the spiral direction of the active water pressure pipe. So that the guide plates can guide the direction of the water body before entering the active water pressure pipe, thereby reducing the rotational water resistance of the active water pressure rotor and reducing water body turbulence and increasing the water inflow.

[0026] It should be further noted that the guide plates on the horizontally arranged guiding outer ring straighten the water body entering the active water pressure pipe from the outside of the water inlet of the active water pressure pipe and reduce turbulence. The guide plates on the horizontally arranged guiding inner ring straighten the water body entering the active water pressure pipe from the inside of the water inlet of the active water pressure pipe and reduce turbulence. The guide plates on the vertically arranged guiding structure straighten the water body entering the active water pressure pipe from the front (i.e., radially) of the water inlet of the active water pressure pipe and reduce turbulence.

[0027] In the present invention, multiple groups of the active water-pressing pipes are arranged in a spiral shape around the outer periphery of the active water-pressing rotor. The active water-pressing pipes are grouped according to the size of their spiral diameters, that is, the water body entering the water inlet of the active water-pressing pipes is refined, so that the water-pressing effect of the active water-pressing pipes on the water body is more stable, and the high-pressure water body ejected from the water outlet of the active water-pressing pipes is more uniform. This is beneficial to reducing turbulence and increasing the pressure of the high-pressure water body in the water outlet cavity.

[0028] In the present invention, a rotating gap is formed between the outer wall of the active water-pressing rotor and the inner wall of the connecting pipe, and there is at least one right-angle bending part at both the front section and the rear section of the rotating gap. Through the design of the right-angle bending part, the rotating gap formed between the active water-pressing rotor and the connecting pipe is no longer a "linear or streamline-shaped" gap, which can effectively reduce and avoid the occurrence of the phenomenon of the edge loss of the upstream water body, and at the same time can also effectively prevent the occurrence of the phenomenon of the downstream water body flowing back.

[0029] It should be noted that in the preferred implementation scheme of the present invention, the number of right-angle bending parts contained in the front section gap is more than the number of right-angle bending parts contained in the rear section gap. The fact that the number of right-angle bending parts in the front section gap is more and the number in the rear section gap is less is conducive to further reducing and avoiding the phenomenon of the edge loss of the upstream water body and preventing the phenomenon of the downstream water body flowing back. The so-called "front section" refers to the side close to the water inlet, and the "rear section" refers to the side close to the water outlet.

[0030] In the present invention, the front gap port of the front section gap is vertically communicated with the water inlet of the active water-pressing pipe, and the rear gap port of the rear section gap is vertically communicated with the water outlet of the active water-pressing pipe. The so-called "vertical communication" means that the central axis of the gap port is perpendicular to the central axis of the active water-pressing pipe. Under the rotating pushing action of the active water-pressing rotor and the active water-pressing pipe, at the water inlet and the water outlet of the active water-pressing pipe, the water flow velocity in the area of the water inlet of the active water-pressing pipe and the water flow velocity pushed to the area of its water outlet are both relatively high. The setting that the gap port is perpendicular and tangent to the water flow direction makes the high-speed flowing water generate a "suction force" on the inside of the gap when flowing through the gap port. Even a small amount of water splashing into the inside of the gap will be sucked out under the action of the "suction force" continuously generated by the subsequent water flow, thereby effectively avoiding or even eliminating the occurrence of the phenomenon of the edge loss or backflow of the water body. It should be noted that when the gap port is not vertically tangent and communicated with the active water-pressing pipe, when the gap port is inclined towards the water source direction, it will inevitably cause the water flow to enter the inside of the gap along the trend; and when the gap port is inclined towards the water flow direction, since the active water-pressing pipe is a variable-diameter flow channel, the water pressure inside the active water-pressing pipe is much greater than the water pressure outside its water inlet, and the high-pressure water body is extremely easy to enter the inside of the gap.

[0031] It should be noted that the water flow velocity at the outlet of the active water pressure pipeline is much greater than that at its inlet. That is to say, the "suction force" generated by the high-speed water flow at the outlet of the active water pressure pipeline on the rear section gap port is greater than the "suction force" generated by the high-speed water flow at the inlet of the active water pressure pipeline on the front section gap port. In order to balance the "suction force" difference between the two, through the design of multiple right-angle bends and the number of right-angle bends contained in the front section gap being more than the number of "right-angle bends" contained in the rear section gap, this suction force difference can be well offset. That is, the design of the right-angle bends and the design of the gap port being vertically tangent and connected to the active water pressure pipeline have a synergistic effect with each other. And in the preferred implementation of the present invention, the gap thickness (diameter) of the rotating gap generally does not exceed 5 mm. The smaller gap thickness makes it easier for the "suction force" difference to be blocked and offset by the right-angle bends.

[0032] In the present invention, the driving device is generally a motor, which is arranged on one side of the water inlet cavity or the water outlet cavity. The driving device sequentially passes through the water outlet cavity and the cavity of the pressurizing mechanism and then is connected to the tail shaft of the active water pressure rotor; or the driving device passes through the water inlet cavity and is connected to the head shaft of the active water pressure rotor.

[0033] Compared with the prior art, the present invention has the following beneficial effects:

[0034] 1. The active water pressure device provided by the present invention adopts an active water pressure rotor and its outer spiral active water pressure pipeline, which can actively pressurize the water body, improve the energy conversion efficiency, and can greatly increase the water head while ensuring a large amount of water, achieving both high head and large flow rate, and obtaining a technical effect of "1 + 1 > 2".

[0035] 2. By adding a reduced-diameter pressurizing pipeline with inner spiral guide vanes behind the main body water pressure device, on the one hand, it promotes the rapid convergence of the high-pressure water flow in multiple spiral motions and realizes secondary pressurization. At the same time, it can effectively avoid the eddy current caused by multiple water flows directly discharging into the water outlet cavity, thereby avoiding the internal consumption of energy and effectively ensuring the water head height of the water outlet.

[0036] 3. The present invention also uses a horizontally arranged outer guide ring, a horizontally arranged inner guide ring, a vertically arranged guide structure and the guide plates they contain, so that the water body entering axially and radially from the water inlet of the active water pressure pipeline is made to have a certain quantity, reduce turbulence, and reduce the rotational resistance generated by the entering water body on the active water pressure pipeline, further ensuring the energy conversion efficiency.
