Description

Technical Field

[0001] The utility model belongs to the technical field of submersible pumps, and more particularly relates to a submersible pump casing and a submersible pump. Background Art

[0002] Submersible pumps are important equipment for extracting water from deep wells. When in use, the entire unit is submerged in water to extract groundwater to the surface. They are widely used for domestic water supply, mine rescue, industrial cooling, farmland irrigation, seawater lifting and ship loading, and can also be used for fountain landscapes.

[0003] Traditional submersible pump housings are usually made of 304 stainless steel and formed by a stretching process. This has high requirements on the material of the housing, and the process is complex and the processing cost is high. Utility Model Content

[0004] To address the complex and costly processing of existing submersible pump casings, this utility model provides a submersible pump casing comprising an outer shell and a base. The outer shell comprises a barrel and an upper cover, which is welded to the top of the barrel to form the submersible pump casing. The upper cover comprises a cover body and side panels, which are circularly connected to the periphery of the cover body to form a disc-shaped upper cover. The side panels are welded to the top of the barrel.

[0005] Furthermore, the cover body is provided with a water outlet pipe installation hole and a power cord installation hole; wherein, the cover body also includes a first protrusion structure provided between the water outlet pipe installation hole and the power cord installation hole.

[0006] Furthermore, the submersible pump housing also includes a water pump handle connected to the upper cover, and a first handle mounting position and a second handle mounting position are provided on the cover body; wherein, the cover body also includes a second protruding structure arranged on one side of the first handle mounting position and a third protruding structure arranged on one side of the second handle mounting position.

[0007] Furthermore, the first protruding structure is connected between the second protruding structure and the third protruding structure, forming an H-shaped reinforcement structure on the cover body.

[0008] Furthermore, the cylinder is formed by rolling a plate into a cylindrical shape and then welding it.

[0009] Furthermore, the bottom end of the cylinder is provided with a flange that matches the base.

[0010] Furthermore, a threaded connection piece passes through the flange and is connected to the base, and a sealing ring is provided between the flange and the base.

[0011] Furthermore, a protrusion that matches the inner wall of the cylinder is provided on the upper end of the base, and the outer diameter of the protrusion is smaller than the inner diameter of the cylinder.

[0012] Furthermore, the utility model provides a submersible pump, which includes any submersible pump housing as described above.

[0013] Technical effects and advantages of this utility model:

[0014] 1. Compared to traditional stamped housings, the housing in this application is welded together from a barrel and a cover, making it easier to manufacture and a simpler process. It only requires welding the barrel and the cover together. Furthermore, the housing in this application has lower material requirements and can be formed from non-stretchable materials, thereby reducing the cost of raw materials for the housing.

[0015] 2. If the upper cover is set to a sheet-like structure, when the upper cover is welded to the top of the cylinder, the welding point between the sheet-like structure and the cylinder, that is, the circumferential side of the sheet-like structure, will have problems such as wrinkles and deformation, resulting in the upper end surface of the upper cover being uneven and unsightly. By setting the upper cover to a disc-shaped structure, since the circumferential arc of the cover body is connected to the cover body side panels, the cover body side panels are welded to the top of the cylinder, and the problem of the upper end surface of the upper cover being uneven and unsightly will not occur. On the other hand, by connecting the cover body side panels with the circumferential arc of the cover body, it is equivalent to providing an arc-shaped flange on the circumferential side of the cover body, which can improve the strength of the circumferential side of the cover body, thereby avoiding the problem that the circumferential side of the upper cover is easily deformed by external force.

[0029] The present invention will be described in further detail below with reference to the accompanying drawings and specific embodiments. The embodiments of the present invention are provided for purposes of illustration and description and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations will be apparent to those skilled in the art. The embodiments are selected and described to better illustrate the principles and practical applications of the present invention and to enable those skilled in the art to understand the present invention and design various embodiments with various modifications suitable for specific applications.

[0030] See also Figure 1 , which is a structural diagram of a submersible pump housing provided by the present invention. Figures 1 to 7 The submersible pump housing includes, for example, an outer shell 10 and a base 40. The outer shell 10 includes a cylinder 30 and an upper cover 20. The upper cover 20 is welded to the top of the cylinder 30 to form the outer shell 10 of the submersible pump.

[0031] It is understood that, compared to conventional stamped housings, the housing 10 of the present application is formed by welding the barrel 30 and the upper cover 20 together, making it easier to manufacture and simplifying the process. It only requires welding the barrel 30 and the upper cover 20 together. Furthermore, the housing 10 of the present application has lower material requirements and can be formed from non-stretchable materials, thereby reducing the raw material cost of the housing 10.

[0032] For example, the cylinder 30 can be made by rolling a plate into a tubular shape and welding it, or it can be made by directly cutting a section of a stainless steel pipe, or it can be made by other processes, which are not limited here.

[0033] Furthermore, the upper cover 20 includes, for example, a cover body 21 and a cover side panel 22. The cover side panel 22 is connected to the circumference of the cover body 21 in an arc shape, forming a disc-shaped upper cover 20. Specifically, the upper cover 20 is welded to the top of the cylinder 30 via the cover side panel 22.

[0034] It is understandable that if the upper cover 20 is set to a sheet-like structure, when the upper cover 20 and the top end of the cylinder 30 are welded together, the welding point between the sheet-like structure and the cylinder 30, that is, the peripheral side of the sheet-like structure, will have problems such as wrinkles and deformation, resulting in the upper end surface of the upper cover 20 being uneven and unsightly.

[0035] By configuring the upper cover 20 in a disc-shaped structure, and since the arc of the circumference of the cover body 21 is connected to the cover side panels 22, the cover side panels 22 are welded to the top of the cylinder 30, eliminating the problem of uneven and unsightly upper end surfaces of the upper cover 20. Furthermore, by connecting the cover side panels 22 to the arc of the circumference of the cover body 21, it is equivalent to providing an arc-shaped flange around the circumference of the cover body 21, which can improve the strength of the circumference of the cover body 21 and thus prevent the circumference of the upper cover 20 from being easily deformed by external impact.

[0036] Furthermore, the cover body 21 is provided with a water outlet pipe mounting hole 23 and a power cord mounting hole 24; wherein, the cover body 21 also includes a first protruding structure 271 provided between the water outlet pipe mounting hole 23 and the power cord mounting hole 24. For example, the middle portion of the cover body 21 is a hole opening area, and the two sides of the hole opening area are handle mounting areas. The water outlet pipe mounting hole 23 is provided at the first end of the hole opening area, and the power cord mounting hole 24 is provided at the second end of the hole opening area; the first protruding structure 271 is provided between the water outlet pipe mounting hole 23 and the power cord mounting hole 24. In addition, the second end of the hole opening area is also provided with a control button mounting hole 25 provided side by side with the power cord mounting hole 24. For example, the water outlet pipe mounting hole 23 is circular, and the side of the first protruding structure 271 close to the water outlet pipe mounting hole 23 is arc-shaped.

[0037] It can be understood that since the water outlet pipe installation hole 23 and the power cord installation hole 24 are opened on the cover body 21, the opening of the holes will inevitably lead to a decrease in the strength of the cover body 21. By setting a first protrusion structure 271 between the water outlet pipe installation hole 23 and the power cord installation hole 24, the strength of the cover body 21 can be improved, and the cover body 21 can be prevented from being deformed during use.

[0038] Furthermore, the submersible pump housing further includes, for example, a water pump handle 50 connected to the upper cover 20. The cover body 21 is provided with a first handle mounting position 261 and a second handle mounting position 262. The water pump handle 50 is mounted on the upper cover 20 via the first handle mounting position 261 and the second handle mounting position 262. For example, the first handle mounting position 261 and the second handle mounting position 262 are located in the handle mounting areas on both sides of the hole area.

[0039] Furthermore, the cover body 21 further includes a second protruding structure 272 disposed on one side of the first handle mounting position 261 and a third protruding structure 273 disposed on one side of the second handle mounting position 262. For example, the second protruding structure 272 and the third protruding structure 273 are located at the junction of the handle mounting area and the hole opening area.

[0040] In one specific embodiment, the first protruding structure 271 is connected between the second protruding structure 272 and the third protruding structure 273, forming an H-shaped reinforcement structure 27 on the cover body 21. It can be understood that, compared to three isolated protruding structures, connecting the first protruding structure 271, the second protruding structure 272, and the third protruding structure 273 to form an H-shaped reinforcement structure 27 can further improve the strength of the cover body 21 and make the arrangement of the protruding structures of the cover body 21 more reasonable.

[0041] Preferably, the cylinder 30 is formed by rolling a 304 stainless steel plate into a cylindrical shape and welding it.

[0042] Furthermore, the bottom end of the cylinder 30 is provided with a flange 31 that cooperates with the base 40, and the threaded connector passes through the flange 31 to connect with the base 40. For example, the flange 31 is a ring-shaped member connected to the bottom end of the cylinder 30 in an arc shape, and the ring-shaped member is provided with multiple threaded connection holes. Correspondingly, the base 40 is also provided with multiple threaded connection holes. The threaded connector passes through the threaded connection holes to connect the flange 31 at the bottom end of the cylinder 30 with the base 40, thereby achieving a fixed connection between the bottom of the cylinder 30 and the base 40.

[0043] Furthermore, a limiting fold 32 is provided around the flange 31 and connected to the arc of the flange 31. The limiting fold 32 extends in the longitudinal direction of the cylinder 30. When the bottom of the cylinder 30 is assembled with the base 40, the limiting fold 32 can limit the base 40 in the lateral direction, so that the base 40 does not move laterally relative to the cylinder 30.

[0044] Furthermore, a sealing ring 60 is provided between the flange 31 and the base 40. It is understood that by providing the sealing ring 60 between the flange 31 and the base 40, the sealing performance of the connection between the flange 31 and the base 40 can be improved, thereby preventing foreign matter from entering the water pump through the connection between the flange 31 and the base 40 during operation, thereby preventing corrosion.

[0045] Furthermore, a protrusion 41 is provided on the upper end of the base 40 to engage with the inner wall of the cylinder 30, and the outer diameter of the protrusion 41 is smaller than the inner diameter of the cylinder 30. It is understood that the engagement of the protrusion 41 with the inner wall of the cylinder 30 can better improve the installation efficiency and assembly limiting effect of the base 40 and the cylinder 30, and reduce the lateral shear force between the base 40 and the cylinder 30.

[0046] Furthermore, the present invention provides a submersible pump comprising any of the submersible pump housings described above. For example, the submersible pump body is disposed within the submersible pump housing, and the top of the rear pump housing 70 of the submersible pump body is connected to the cover body 21 via a threaded connector to secure the rear pump housing. Only the top end of the submersible pump body is connected to the housing 10. During maintenance, only the threaded connector between the flange 31 and the base 40 and the threaded connector between the top end of the submersible pump body and the housing 10 need be removed. The housing 10 can then be removed for maintenance or replacement, resulting in high assembly and disassembly efficiency.
