Technical Field

[0001] The utility model relates to the technical field of submersible pump motors, in particular to a fixed connection structure for the end ring of a submersible pump motor. Background Art

[0002] The end ring of a submersible pump motor generally refers to a part of the rotor winding in the submersible pump motor. It plays a key role in the motor structure, especially in a wound-rotor asynchronous motor. The end ring, also known as the end ring of a squirrel-cage rotor, is an annular structure made of conductive material. It connects the two ends of the rotor winding to form a closed-loop circuit.

[0003] In the prior art (a Chinese invention patent application with the application number 202021670115.9 and the patent name of a fixed connection structure for the end ring of a submersible pump motor), it includes a submersible pump motor housing, a clamp, and an end ring. The end of the submersible pump motor housing is provided with an outer clamping groove and an inner clamping groove. The clamp includes an outer clamp and an inner clamp. The outer clamping groove is equipped with the outer clamp, the inner clamping groove is equipped with the inner clamp, the end ring is located between the outer clamp and the inner clamp, and the end ring is provided with evenly distributed screw holes. The utility model adopts a fixed connection structure for the end ring of a submersible pump motor, which meets the high-efficiency assembly requirements of the automatic winding process of the stator coil of a stainless steel submersible pump motor. At the same time, through the two-row clamp-type positioning design, the connection strength of the end ring is enhanced, the positioning is accurate, and the installation is convenient and efficient.

[0028] When installing the end ring and the submersible pump motor housing, multiple clamps are still needed to install the end ring. However, when installing the clamp, due to the tightness of the clamp itself, the user is required to tighten it in advance with pliers or other tightening tools. Then, since multiple clamps are used, the user is required to spend his own effort and extra installation time to install them, which is time-consuming and labor-intensive. Moreover, after long-term use, when the end ring or the structure inside the submersible pump motor located below the end ring needs to be maintained, the clamps still need to be disassembled one by one, which is time-consuming and labor-intensive, increases the user's workload, and is inconvenient to use. Therefore, after research, the inventor provides a submersible pump motor end ring fixed connection structure. Through the setting of the connecting component, the end ring can be installed with the submersible pump motor housing without the need for a clamp, so that the user does not need to use and carry the clamp fastening tool, which saves time and effort. Moreover, through the use of the connecting component of the present technical solution, the end ring can be supported by the connecting component after the installation is completed, so as to avoid the end ring from falling during use. Moreover, when the end ring or the remaining parts in the submersible pump motor are subsequently maintained, it is only necessary to simply twist the connecting component to disassemble it, which reduces the user's installation and disassembly burden, and improves the user's installation efficiency of the end ring, which is easy to use, thereby solving the above-mentioned defects.

[0029] In conjunction with the accompanying drawings, some embodiments of the present invention are described in detail below. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0030] Please refer to Figures 1 to 9, an embodiment of the utility model provides a fixed connection structure for the end ring of a submersible pump motor, which includes a submersible pump motor housing 1 and an end ring 2, and the end ring 2 is located in the inner cavity of the submersible pump motor housing 1. A plurality of connection components 3 are arranged on the outer surface of the submersible pump motor housing 1. The specific number of the connection components 3 can be selected according to the actual use situation. The connection component 3 includes an installation box 31, and the outer surface of the installation box 31 is connected to the outer surface of the submersible pump motor housing 1. And the overall structure inside the connection component 3 is waterproofed. A plurality of connection boxes 32 are connected to the outer surface of the installation box 31. A rotating rod 33 is rotatably connected to the inner cavity of the connection box 32. A worm gear 34 is connected to the outer surface of the rotating rod 33. A worm 35 is rotatably connected to the inner cavity of the connection box 32, and the worm 35 meshes with the worm gear 34. One end of the worm 35 penetrates to the outside of the connection box 32 and is connected with a torsion block convenient for the user to twist. And the area where the worm 35 penetrates and contacts the connection box 32 is sealed. A plurality of long rods 36 are arranged through the inner cavity of the submersible pump motor housing 1, and one end of the long rod 36 penetrates to the inner cavity of the installation box 31. And the area where the long rod 36 penetrates and contacts the installation box 31 is sealed;

[0031] Please refer to Figures 1 to 8 , a plurality of round rods 37 are rotatably connected to the bottom and top of the inner cavity of the installation box 31. Three meshing first bevel gears 38 are respectively connected to the outer surfaces of the rotating rod 33, the round rod 37 and the long rod 36. A plurality of fixing plates 39 are connected to the inner cavity of the submersible pump motor housing 1 and are located below the end ring 2. A running rod 310 is rotatably connected to the outer surface of the fixing plate 39. A top plate 311 in contact with the end ring 2 is connected to the outer surface of the running rod 310. Two meshing second bevel gears 312 are respectively connected to the outer surface of the running rod 310 and one end of the long rod 36. A running frame 313 is connected to the outer surface of the round rod 37. A plurality of moving rods 314 are slidably connected to the inner cavity of the installation box 31, and the outer surfaces of the moving rods 314 are slidably connected to the inner side of the running frame 313. The shape of the installation box 31 is annular. A plurality of guide blocks 315 are slidably connected to the top of the inner cavity of the installation box 31. A clamping rod 316 is connected to one side of the guide block 315, and one end of the clamping rod 316 away from the guide block 315 penetrates to the inner cavity of the submersible pump motor housing 1.

Among them, the round rod 37 drives the operation frame 313 to rotate and swing. The operation frame 313 drives the moving rod 314 to move away from the card slot 21. The moving rod 314 drives the guide block 315 and the clamping rod 316 away from the card slot 21. At this time, the long rod 36 drives the second bevel gear 312 to engage and rotate. The second bevel gear 312 drives the operation rod 310 to rotate and swing away from the end ring 2. The operation rod 310 drives the top plate 311 to move synchronously. At this time, the user can manually take out the end ring 2 for easy use.

[0033] In summary, the working principle of a fixed connection structure for the end ring of a submersible pump motor according to an embodiment of the present invention is as follows: When the user installs the end ring 2 and the submersible pump motor housing 1, the connection assembly 3 can be manually twisted. The connection assembly 3 contacts the card slot 21 on the outer surface of the end ring 2, so as to clamp the end ring 2 by using the connection assembly 3. During the clamping process, the end ring 2 can also be supported by the connection assembly 3, so as to complete the working purpose of installing the end ring 2 and the submersible pump motor housing 1 for easy use.
