Description

Technical Field

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

[0002] Integrated water pumps are widely used in fields such as urban drainage, sewage treatment, industrial water supply, and agricultural irrigation. Early water pumps usually had a single pump head structure, which meant there was only one suction and discharge port. However, with technological progress and changes in market demands, higher requirements have been put forward for the performance and efficiency of water pumps. However, in application scenarios that require higher flow rates or greater pressures, single-pump-head water pumps cannot operate effectively and quickly, resulting in low efficiency. Moreover, the heat generated during the high-speed operation of the water pump cannot simultaneously cool the heating components, resulting in poor cooling effect, increasing unnecessary energy consumption and costs, and the overall design performance of the water pump is not high, making it inconvenient to use. In summary, urgent improvements are needed. Content of the Utility Model

[0003] The purpose of the utility model is to provide an integrated water pump with a double pump head structure in view of the defects and deficiencies of the prior art, which has the advantages of improving work efficiency with a double pump head structure and being able to cool the heating components simultaneously without increasing energy consumption.

[0004] To achieve the above purpose, the technical solution adopted by the utility model is: an integrated water pump with a double pump head structure, including:

[0005] A pump body;

[0006] A controller, assembled at one end of the pump body and internally provided with a control circuit board, the controller being provided with an inlet end and an outlet end;

[0007] A double-shaft extension motor, assembled inside the pump body and used to provide power;

[0008] Two turbines, respectively fixedly assembled at both ends of the output shaft of the double-shaft extension motor;

[0009] A first pump head, sleeved on one of the turbines and assembled at one end of the pump body, the first pump head being provided with a first liquid inlet and a first liquid outlet;

[0010] A second pump head, sleeved on the other turbine and assembled at the other end of the pump body, the second pump head being provided with a second liquid inlet and a second liquid outlet;

[0013] A cooling structure, assembled within the pump body and the controller, with the pump body and the controller being in communication;

[0014] When the double-shaft motor is driven, the turbine is driven to rotate, and liquid is simultaneously sucked into the first pump head and the second pump head from the first liquid inlet and the second liquid inlet, and then flows out from the first liquid outlet and the second liquid outlet. Part of the liquid from the first liquid outlet or the second liquid outlet flows into the cooling structure through the first branch pipe, and then flows back to the first liquid inlet or the second liquid inlet through the second branch pipe.

[0015] The present utility model is further configured such that the first pump head and the second pump head are assembled in parallel or in series at both ends of the pump body.

[0016] The present utility model is further configured such that the turbine includes: a shaft sleeve sleeved on the output shaft of the double-shaft motor, a first spiral member spirally provided on the shaft sleeve and close to the liquid inlet side, and a second spiral member spirally provided on the shaft sleeve, on the side away from the liquid inlet, and for cooperating with the first spiral member to guide the liquid.

[0017] The present utility model is further configured such that the shaft sleeve, the first spiral member, and the second spiral member are integrally formed.

[0018] The present utility model is further configured such that the cooling structure includes: a first cooling tank provided within the controller, and a second cooling tank provided within the pump body and in communication and cooperation with the first cooling tank.

The double-pump head structure design enables the liquid to be sucked and discharged by the two pump heads at the same time, improving the flow rate and working efficiency of the hand pump. Part of the liquid in the first liquid outlet or the second liquid outlet flows into the cooling structure from the first branch pipe, and then flows back to the first liquid inlet or the second liquid inlet through the second branch pipe. During this process, when the driving device and the controller in the integrated water pump use the double-pump head to extract liquid, heat is continuously generated, and this part of the liquid plays a role in cooling and temperature reduction for the driving device and the controller. This part of the liquid flows into the cooling structure from the first liquid outlet or the second liquid outlet, and then flows back to the first liquid inlet or the second liquid inlet, enabling the overall water pump to be cooled and temperature-reduced, and at the same time, there is no need to add additional devices for cooling to avoid additional energy consumption. Therefore, the integrated water pump with a double-pump head structure is realized, which improves the working efficiency, and can simultaneously cool the heating components without increasing energy consumption.

DETAILED DESCRIPTION

[0029] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0030] This specific embodiment is merely an explanation of the present invention and is not a limitation of the present invention. After reading this specification, those skilled in the art may make non-creative modifications to the present embodiment as needed, but such modifications are protected by patent law as long as they are within the scope of the claims of the present invention.

[0031] Embodiment 1

[0032] Reference Figures 1 - 3 The present embodiment relates to an integrated water pump with a dual pump head structure, including: a pump body 100, a controller 200, a dual-axle motor 300, a turbine 400, a first pump head 500, a second pump head 600, a first branch pipe 700, a second branch pipe 800 and a cooling structure.

[0033] Among them, the controller 200 is assembled at one end of the pump body 100, and a control circuit board 210 is arranged therein. The control circuit board 210 is used to control the on-off state of the water pump. The controller 200 is also provided with an inlet end 220 and an outlet end 230 for connecting the first branch pipe 700 and the second branch pipe 800 respectively. The double-shaft extension motor 300 is assembled in the pump body 100 and is used to provide power support. In other embodiments, other types of motors can also be used. There are two turbines 400, which are respectively fixedly assembled at both ends of the output shaft of the double-shaft extension motor 300. Driven by the double-shaft extension motor 300, the turbines 400 generate pressure in the double pump heads, facilitating the liquid to be sucked into the double pump heads. The first pump head 500 is sleeved on one of the turbines 400 and is assembled at one end of the pump body 100. The first pump body 100 is provided with a first liquid inlet 510 and a first liquid outlet 520. The first pump head 500 is responsible for sucking the liquid from the first liquid inlet 510, pressurizing the liquid through the rotation of the turbine 400, and then discharging it through the first liquid outlet 520. The second pump head 600 is sleeved on the other turbine 400 and is assembled at the other end of the pump body 100. The second pump body 100 is provided with a second liquid inlet 610 and a second liquid outlet 620. Similar to the first pump head 500, the second pump head 600 is also responsible for sucking the liquid from the second liquid inlet 610, pressurizing the liquid through the rotation of the turbine 400, and then discharging it through the second liquid outlet 620. In this way, the double pump heads can work simultaneously, increasing the total flow rate and working efficiency of the water pump. One end of the first branch pipe 700 communicates with the first liquid outlet 520, and the other end communicates with the inlet end 220 of the controller 200. One end of the second branch pipe 800 communicates with the first liquid inlet 510, and the other end communicates with the outlet end 230 of the controller 200. The cooling structure is assembled in the pump body 100 and the controller 200, and the pump body 100 and the controller 200 are communicated. Through the cooling cycle formed by the connection of the first branch pipe 700 and the second branch pipe 800 with the cooling structure, the temperature of the water pump can be effectively controlled, preventing damage caused by overheating during high-speed operation, and forming a closed-loop cooling system.

[0034] Specifically in this embodiment, one ends of the first branch pipe 700 and the second branch pipe 800 respectively communicate with the first liquid outlet 520 and the first liquid inlet 510 of the first pump head 500. In other embodiments, one ends of the first branch pipe 700 and the second branch pipe 800 can also respectively communicate with the second liquid outlet 620 and the second liquid inlet 610 of the second pump head 600. Since the first pump head 500 and the second pump head 600 are symmetrically arranged, the cooling effect achieved by connecting to the second pump head 600 is the same as that achieved by connecting to the first pump head 500.

[0035] Thus, when driving the double-extended-shaft motor 300, the turbine 400 is driven to rotate. Under the action of the turbine 400, the liquid is simultaneously sucked into the first pump head 500 and the second pump head 600 from the first liquid inlet 510 and the second liquid inlet 610, and then flows out from the first liquid outlet 520 and the second liquid outlet 620. Part of the liquid in the first liquid outlet 520 flows into the cooling structure from the first branch pipe 700, and then flows back to the first liquid inlet 510 through the second branch pipe 800. The double-pump-head structure improves the flow rate and efficiency of the integrated water pump. At the same time, the integrated cooling structure can cool the double-extended-shaft motor 300 and the controller 200 simultaneously without increasing additional energy consumption. Among them, the flow rate of this part of the liquid is less than the flow rate of the liquid outlet, and the flow rate of this part of the liquid is 5%-10% of the total flow rate of any one pump head, realizing that no external additional cooling water source is required, and the normal liquid extraction work of the integrated water pump is not affected. Specifically, in this embodiment, the first branch pipe 700 and the second branch pipe 800 can control the flow rate of part of the liquid through a valve switch. In other embodiments, the flow rate of part of the liquid can also be controlled by adjusting the thickness of the first branch pipe 700 and the second branch pipe 800.

[0036] In this embodiment, the first pump head 500 and the second pump head 600 are assembled in parallel or in series at both ends of the pump body 100. When the user needs a large flow rate for the two pump heads, the water pipes can be connected in parallel. When a large pressure is required, the user can connect the two pump heads in series. Therefore, when the first pump body 100 and the second pump body 100 are assembled in parallel, the two pump heads work independently, and their liquid inlets and outlets are separated from each other without interference. The two pump heads can draw more liquid at the same time, providing a higher flow rate. In addition, when arranged in parallel, even if one pump head fails, the other pump head can still work normally, ensuring the continuous operation of the water pump. When the first pump head 500 and the second pump head 600 are assembled in series, the two pump heads are connected in sequence, and the liquid outlet of the first pump head is connected to the liquid inlet of the second pump head, which is used to increase the lift (pressure) of the water pump. Through the series connection method, the second pump head can further increase the pressure of the liquid, enabling it to overcome greater resistance and be transported farther or higher.

[0037] In this embodiment, referring to Figure 2 , the turbine 400 includes: a shaft sleeve 410, a first spiral member 420 and a second spiral member 430. The shaft sleeve 410 is sleeved on the output shaft of the double-extended-shaft motor 300 to ensure that the turbine 400 can rotate synchronously with the rotation of the motor. The first spiral member 420 is spirally arranged on the shaft sleeve 410 and close to the liquid inlet side, which guides the liquid to smoothly enter the turbine 400 and helps the liquid to accelerate. The second spiral member 430 is spirally arranged on the shaft sleeve 410, on the side far from the liquid inlet, and is used to cooperate with the first spiral member 420 to guide the liquid, which is used to export the liquid from the center of the turbine 400 to the outside. Further improving the overall working efficiency of the water pump.

[0038] In this embodiment, the bushing 410, the first helical member 420, and the second helical member 430 are integrally formed, which can reduce the number of components during the assembly process, simplify the manufacturing process, and at the same time enhance the strength and stability of the overall structure.

[0039] In this embodiment, referring to Figures 3 - 4 , the cooling structure includes: a first cooling tank 910 disposed within the controller 200, and a second cooling tank 920 disposed within the pump body 100 and communicatively connected to the first cooling tank 910. The cooling structure is to effectively reduce the heat generated during the operation of the water pump and keep the double-shaft extension motor 300 and the controller 200 within a reasonable temperature range. Specifically, a part of the liquid in the first liquid outlet 520 flows from the first branch pipe 700 into the first cooling tank 910 to cool down the control circuit board 210 in the controller 200, then flows through the second cooling tank 920 to cool down the double-shaft extension motor 300, and then the liquid returns to the first cooling tank 910 and the outlet end 230 flows from the second branch pipe 800 into the first liquid inlet 510, thus forming a closed cooling circulation system that can simultaneously cool down the heat-generating components without adding additional energy consumption, and at the same time helps to improve the efficiency of the water pump and extend its service life.

[0040] In this embodiment, referring to Figure 4 , the first cooling tank 910 includes: a first connecting pipe 911 with one end communicatively connected to the first cooling tank 910 and the other end communicatively connected to one end of the second cooling tank 920, and a second connecting pipe 912 with one end communicatively connected to the other end of the second cooling tank 920 and the other end communicatively connected to the outlet end 230. The first connecting pipe 911 and the second connecting pipe 912 are further arranged to form a closed-loop coolant flow path.

[0041] In this embodiment, referring to Figures 1 - 2 Connectors 110 for connecting the first pump head 500 and the second pump head 600 are provided on both sides of the pump body 100, and the controller 200 is connected to the upper side of the connectors 110. This enables the first pump head 500 and the second pump head 600 to be firmly assembled at both ends of the pump body 100, and the pump body 100 is connected to the controller 200 through the connectors 110, ensuring the structural stability of the entire system. Moreover, the integrated setting also makes the overall water pump structure more compact, smaller in size, and more convenient to carry and use.

[0042] In this embodiment, referring to Figure 1 , a control panel 240 and symmetrically arranged carrying handles 250 are further provided on the side of the controller 200 facing away from the pump body 100. The control panel 240 allows users to conveniently monitor and adjust the working parameters of the pump, and the design of the carrying handles 250 makes the entire device easier to carry, increasing the portability of the device.

[0043] Embodiment 2

[0044] This embodiment is basically the same as Embodiment 1, except that: one end of the first branch pipe 700 communicates with the first liquid outlet 520, and the other end communicates with the inlet end 220 of the controller 200; one end of the second branch pipe 800 communicates with the second liquid inlet 610, and the other end communicates with the outlet end 230 of the controller 200. Part of the liquid in the first liquid outlet 520 flows into the cooling structure through the first branch pipe 700, and then flows back to the second liquid inlet 610 through the second branch pipe 800. Specifically, part of the liquid in the first liquid outlet 520 flows into the first cooling tank 910 through the first branch pipe 700 to cool the control circuit board 210 in the controller 200, and then flows through the second cooling tank 920 to cool the double-shaft motor 300. Then, the liquid flows back to the outlet end 230 in the first cooling tank 910 and flows into the second liquid inlet 610 through the second branch pipe 800, thus forming a closed cooling circulation system. Therefore, this embodiment can also cool the heating components simultaneously with Embodiment 1 without increasing additional energy consumption. More specifically, since the first branch pipe 700 and the second branch pipe 800 are symmetrically arranged, part of the liquid flows into the first branch pipe 700 from the first liquid outlet 520 of the first pump head 500. After flowing through the first cooling tank 910 and the second cooling tank 920, an equal amount of this part of the liquid flows into the second liquid inlet 610 of the second pump head 600 through the second branch pipe 800 to complete a cooling cycle. The connection mode of the first branch pipe 700 and the second branch pipe 800 enables the water pump to reach a better balance state during operation, improving the overall performance and stability of the water pump.

[0045] Specifically in this embodiment, one end of the first branch pipe 700 and the second branch pipe 800 communicates with the first liquid outlet 520 of the first pump head 500 and the second liquid inlet 610 of the second pump head 600 respectively. In other embodiments, one end of the first branch pipe 700 and the second branch pipe 800 communicates with the second liquid outlet 620 of the second pump head 600 and the first liquid inlet 510 of the first pump head 500 respectively. Since the first pump head 500 and the second pump head 600 are symmetrically arranged, the same cooling effect and stability as this embodiment can also be achieved.

[0046] The above is only used to illustrate the technical solution of the present invention rather than to limit it. Any other modifications or equivalent replacements made by those of ordinary skill in the art to the technical solution of the present invention should be covered within the scope of the claims of the present invention as long as they do not depart from the spirit and scope of the technical solution of the present invention.
