Description

Technical Field

[0001] The utility model relates to the technical field of water pumps, in particular to an integrated water pump structure. Background Art

[0002] As the core equipment for fluid transportation, water pumps are widely used in the fields of domestic water supply, mine rescue, industrial cooling, farmland irrigation, seawater lifting, ship load adjustment, etc. The water pump structure is often equipped with a high-speed motor. In actual application, when the motor rotates at high speed, factors such as internal resistance, current changes, and mechanical friction work together to convert energy into heat energy. As the motor speed increases, this heat gradually increases. The long-term accumulation of high heat will have a serious impact on the performance and life of the water pump, so the water pump needs to be cooled. Among the existing water pump cooling and cooling solutions, most of them use additional cooling devices to cool the water pump, which not only increases energy consumption and costs, but also increases the difficulty of transportation, control, and inconvenience, and is in urgent need of improvement. Utility Model Content

[0003] The purpose of the present invention is to address the defects and shortcomings of the existing technology and provide an integrated water pump structure, which has the advantages of assembling the cooling system and the drive device into one body and cooling the drive device without consuming energy.

[0004] To achieve the above purpose, the technical solution adopted by the present invention is: an integrated water pump structure, comprising:

[0005] A driving device for providing driving force;

[0006] The pump body has one end for the driving device to be built in, and the other end is provided with a liquid guide cavity, and the output end of the driving device extends into the liquid guide cavity;

[0007] An annular guide groove is provided on the outer peripheral side of the pump body at one end where the driving device is mounted;

[0008] a liquid inlet, which is provided on one end of the pump body provided with the liquid guiding cavity and is connected to the liquid guiding cavity;

[0009] a liquid outlet, which is provided on a side of one end of the pump body where the liquid guiding cavity is provided, and is connected to the liquid guiding cavity;

[0010] a first branch pipe, one end of which is connected to the liquid inlet, and the other end of which is connected to one end of the annular guide groove; and

[0011] a second branch pipe, one end of which is connected to the liquid outlet, and the other end of which is connected to the other end of the annular guide groove;

[0012] When the driving device is turned on, the liquid enters the liquid guide cavity through the liquid inlet and flows out from the liquid outlet, wherein part of the liquid flows from the second branch pipe into the annular guide groove, and then flows through the first branch pipe back to the liquid inlet.

[0013] The present invention is further provided that the pump body comprises: a first shell and a second shell detachably assembled on the first shell, and the driving device is assembled in the first shell.

[0014] The present invention is further provided with the first shell comprising: a first shell body and a cover body sleeved on the outer periphery of the first shell body; the outer periphery of the first shell body is provided with the annular guide groove, and the annular guide groove and the cover body enclose a channel for liquid to flow back to the first branch pipe.

[0015] The present invention is further provided that the pump body further comprises: a barrier member assembled between the first shell and the second shell, the barrier member being provided with an output hole for the output end of the driving device to extend out.

[0016] The utility model is further provided that the annular guide groove is spiral.

[0017] The present invention is further provided with a first switch at one end of the first branch pipe connected to the liquid inlet.

[0018] The present invention is further provided with a second switch at one end of the second branch pipe connected to the liquid outlet.

[0019] After adopting the above technical solution, the beneficial effects of the present invention are as follows: in the present invention, under the driving action of the driving device, the liquid enters the liquid guide cavity through the liquid inlet, and is then directly discharged from the liquid outlet, wherein part of the liquid flows into the annular guide groove through one end of the second branch pipe connected to the liquid outlet, and then flows back to the first branch pipe through the annular guide groove, and finally flows back to the liquid inlet. In this process, the driving device continuously generates heat during operation, and the pump body becomes hot, and this part of the liquid plays a role in dissipating heat and cooling the pump body. The present invention sets a second branch pipe to introduce the liquid into the annular guide groove, and then flows back and discharges it from the first branch pipe, so that a cooling path is formed in the annular guide groove for the pump body equipped with the driving device at one end, which dissipates heat and cools the pump body, and at the same time, there is no need to add additional devices to avoid generating additional energy consumption and reduce costs. In addition, the cooling system of the pump body is assembled with the driving device, which is convenient for control and transportation, and reduces the floor space occupied during operation.

DETAILED DESCRIPTION

[0025] The present invention will be described in further detail below with reference to the accompanying drawings.

[0026] 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 as long as they are within the scope of the claims of the present invention, they are protected by patent law.

[0027] This embodiment relates to an integrated water pump structure, referring to Figure 1-Figure 2The pump body 100 includes a drive device (not shown in the drawings), a pump body 100, an annular guide groove 200, a liquid inlet 122, a liquid outlet 123, a first branch pipe 310, and a second branch pipe 320. The drive device is used to provide driving force. The drive device is housed at one end of the pump body 100, and a liquid guide cavity 121 is provided at the other end. The output end of the drive device extends into the liquid guide cavity 121. The annular guide groove 200 is provided on the outer peripheral side of the end of the pump body 100 equipped with the drive device. The liquid inlet 122 is provided on the end of the pump body 100 provided with the liquid guide cavity 121 and is connected to the liquid guide cavity 121. The liquid outlet 123 is provided on the side of the end of the pump body 100 provided with the liquid guide cavity 121 and is connected to the liquid guide cavity 121. The first branch pipe 310 has one end connected to the liquid inlet 122 and the other end connected to one end of the annular guide groove 200. The second branch pipe 320 has one end connected to the liquid outlet 123 and the other end connected to the other end of the annular guide groove 200. The working principle and process of this integrated water pump structure are as follows: Under the driving action of the drive device, liquid enters the liquid guide cavity 121 through the liquid inlet 122 and is discharged directly from the liquid guide cavity 121 to the liquid outlet 123. Part of the liquid flows into the annular guide groove 200 through the end of the second branch pipe 320 connected to the liquid outlet 123. The liquid flows through the annular guide groove 200 on the outer peripheral side of the end of the pump body 100 equipped with the drive device, then flows into the first branch pipe 310 and returns to the liquid inlet 122 from the end of the first branch pipe 310 connected to the liquid inlet 122. During this process, the operation of the drive device continuously generates heat, causing the pump body 100 to heat up. The annular guide groove 200 is located at the end of the pump body 100 equipped with the drive device. Liquid flows from the second branch pipe 320 into the annular guide groove 200 and then flows out of the first branch pipe 310, forming a cooling path in the annular guide groove 200 to cool the heated parts of the pump body 100. The return liquid flow rate flowing into the second branch pipe 320, into the annular guide groove 200, and then into the first branch pipe 310 is less than the liquid flow rate flowing directly out through the liquid outlet 123. The return liquid flow rate is 5%-10% of the liquid flow rate flowing directly out of the liquid outlet 123, which does not affect the normal liquid extraction operation of the integrated water pump structure. Compared with traditional water pumps, the integrated water pump structure does not require additional devices to cool the pump body 100, so there is no additional energy consumption, which plays a role in cost saving. At the same time, the present invention integrates the cooling system for cooling the pump body 100 with the drive device, achieving a small volume at the same flow rate, facilitating control and transportation, increasing work convenience, and reducing the floor space occupied during operation.

[0028] In this embodiment, the driving device is a high-speed motor. In some embodiments, the driving device can also be a servo motor. In this embodiment, the liquid is cooling water. In other embodiments, the liquid can also be an actual liquid in the working environment, such as seawater, river water, etc.

[0029] In this embodiment, referring to Figure 1-Figure 2The pump body 100 includes: a first shell 110 and a second shell 120 that can be detachably assembled on the first shell 110. A driving device is assembled in the first shell 110. The liquid guide cavity 121 is arranged in the second shell 120. One end of the first branch pipe 310 is connected to the liquid inlet 122 and is connected to the second shell 120. One end of the second branch pipe 320 is connected to the liquid outlet 123 and is connected to the second shell 120.

[0030] Further, refer to Figure 3 The first housing 110 includes a first housing body 111 and a cover 112 that fits around the outer periphery of the first housing body 111. An annular guide groove 200 is defined on the outer periphery of the first housing body 111. The annular guide groove 200 and the cover 112 define a channel for liquid to flow back to the first branch pipe 310. This channel serves as a cooling channel for the liquid to flow back to the first branch pipe 310 through the second branch pipe 320. The cover 112 also includes corresponding mounting holes for the first and second branch pipes 310, 320.

[0031] In this embodiment, referring to Figure 1-Figure 3 The pump body 100 further includes a barrier member 400 mounted between the first housing 110 and the second housing 120. The barrier member 400 defines an output hole 410 through which the output end of the drive device extends. The barrier member 400 prevents liquid or other impurities within the pump body 100 from directly contacting the drive device, thereby protecting the drive device from damage and extending its service life. The output hole 410 on the barrier member 400 ensures that the output end of the drive device can extend and, in turn, into the liquid guide cavity 121. When the drive device is actuated, the output end of the drive device can output liquid from the liquid guide cavity 121 to the liquid outlet 123.

[0032] In this embodiment, the annular guide groove 200 is spirally shaped and winds around the outer circumference of the first shell body 111 to increase the cooling area.

[0033] Furthermore, a first switch 510 is provided at the end of the first branch pipe 310 connected to the liquid inlet 122. Before activating the drive device, the first switch 510 is closed to prevent liquid from entering the liquid inlet 122 and flowing directly through the first branch pipe 310 into the annular guide groove 200. A second switch 520 is provided at the end of the second branch pipe 320 connected to the liquid outlet 123. The first switch 510 and the second switch 520 cooperate to open and close the liquid pipeline flowing through the annular groove.

[0034] The above is only used to illustrate the technical solution of the present invention and is not intended to limit it. Other modifications or equivalent substitutions made to the technical solution of the present invention by ordinary technicians in this field should be included in 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.
