Technical Field

[0002] A load switch energy storage motor is a motor specifically designed to power the spring energy storage system in the operating mechanism of a load switch. The sole task of the energy storage motor is to compress or stretch these energy storage springs, converting electrical energy into the spring's potential energy and storing it to prepare for the next opening or closing operation. During the compression or stretching of the energy storage springs, the motor generates heat due to the gradually increasing load, necessitating timely heat dissipation.

[0003] The motor cooling structure disclosed in CN117937828A includes a motor body with a heat dissipation shell. The outer peripheral wall of the heat dissipation shell is hinged to a heat dissipation fin and a cleaning frame that are evenly distributed in the circumferential direction. The heat dissipation fins and the cleaning frame are arranged alternately. A cleaning rod that presses against one side of the heat dissipation fin is fixedly provided on the free end side of the cleaning frame. A synchronous drive group located at one end of the heat dissipation fin is sleeved on the heat dissipation shell. Under the action of the synchronous drive group, the evenly distributed heat dissipation fins rotate synchronously. A temperature control assembly that controls the swing of the heat dissipation fins through the synchronous drive group is provided on the outside of the heat dissipation shell.

[0004] Based on the above technical features, the problem is that in the prior art, after the cleaning rod cleans the heat dissipation fins, dust and adhesive residue are easily left on the cleaning rod, resulting in incomplete cleaning and thus affecting the heat dissipation of the motor.

The two sliders 14 correspond one-to-one with the two second guide grooves 16, and each slider 14 is limited and slidably engaged with the corresponding second guide groove 16.

[0059] The slip ring 9 is equipped with a first drive mechanism that drives the rotating ring 6 to rotate. The rotating ring 6 drives the second heat sink 7 to be aligned or misaligned with the corresponding first heat sink 4.

[0060] The first driving mechanism includes a first electromagnet 13.

[0061] Two first limiting grooves 11 are formed on the end of the slip ring 9 near the first heat dissipation fin 4 along the circumference of the motor shaft 2. The two first limiting grooves 11 are evenly distributed along the circumference of the motor shaft 2. The cross-section of each first limiting groove 11 along the axial direction of the motor shaft 2 is convex.

[0062] Each first limiting groove 11 has a first electromagnet 13 fixedly installed at the front end of the first limiting groove 11 in the counterclockwise rotation direction of the motor shaft 2.

[0063] Each first limiting groove 11 is fitted with a matching first limiting block 10 made of metal. Both first limiting blocks 10 are fixedly connected to the rotating ring 6.

[0064] A first spring 12 is installed in each first limiting groove 11 along the sliding direction of the first limiting block 10. Each first spring 12 is an arc-shaped spring.

[0065] One end of each first spring 12 is fixedly connected to the first limiting block 10 located in the first limiting groove 11, and the other end is fixedly connected to the slip ring 9.

[0066] In this embodiment, each first limiting block 10 is located between the first electromagnet 13 and the first spring 12 within the first limiting groove 11.

[0067] Two first guide grooves 15 are formed on the casing 1 along the circumference of the motor shaft 2. The two first guide grooves 15 are evenly distributed along the circumference of the motor shaft 2 and correspond one-to-one with two first limiting grooves 11.

Each slider 14 is limited and slidably engaged with the first guide groove 15 connected to the second guide groove 16.

[0068] The mounting bracket 3 is also equipped with an air blowing mechanism that blows air into the air hole.

[0069] The air blowing mechanism includes an air chamber 24, which is annular and circumferentially located within the housing 1 of the motor shaft 2. Multiple first through holes 17 are radially formed on the housing 1 along the motor shaft 2, and these holes are evenly spaced along the axial direction of the motor shaft 2. Each of the first through holes 17 corresponds to a corresponding air hole and connects the air chamber 24 to the corresponding air hole.

[0070] Each piston cylinder 32's rodless chamber is connected to the gas chamber 24 via a pipe with a second one-way valve 37.

[0071] Specifically, the pipeline includes a connecting pipe 36 and an airflow passage 38. The airflow passage 38 is located inside the housing 1 and connects to the air chamber 24. The connecting pipe 36 is fixed between the housing 1 and the piston cylinder 32. The connecting pipe 36 connects the rodless chamber of the piston cylinder 32 and the airflow passage 38. A second one-way valve 37 is fixed inside the connecting pipe 36.

[0072] Both piston cylinders 32 are provided with air inlets that communicate with the rodless chamber and are equipped with a first one-way valve 35.

[0073] An annular stop block 33 is provided in the rodless chamber of each of the two piston cylinders 32, and each annular stop block 33 is coaxially fixed to its respective piston cylinder 32. The connection point between each connecting pipe 36 and its respective piston cylinder 32 is located between the annular stop block 33 and the air inlet inside the respective piston cylinder 32.

[0074] The air chamber 24 is equipped with an exhaust assembly and a switch assembly that controls the simultaneous opening or closing of all the first through holes 17.

[0075] Specifically, the exhaust assembly includes an annular retaining ring 39, which is coaxial with the motor shaft 2 and slidably mounted within the air chamber 24 along the axial direction of the motor shaft 2. The annular retaining ring 39 makes sealing sliding contact with the two curved inner walls of the air chamber 24. This seal is a sliding seal, which is prior art and will not be described in detail here.

[0076] Multiple fourth springs 40 are arranged inside the air cavity 24 along the sliding direction of the annular retaining ring 39, and the multiple fourth springs 40 are evenly distributed along the circumference of the motor shaft 2. One end of each fourth spring 40 is fixedly connected to the annular retaining ring 39, and the other end is fixedly connected to the housing 1.

[0077] It should be noted that each airflow channel 38 is connected to the springless cavity of the air chamber 24.

[0078] Specifically, the switch assembly includes an annular rotating plate 25, which is coaxial with the motor shaft 2 and rotatably mounted in the springless cavity of the air chamber 24.

[0084] A third electromagnet 30 is fixedly installed at the front end of each second limiting groove 28 along the counterclockwise rotation direction of the motor shaft 2.

[0085] In this embodiment, each second limiting block 27 is located between the third electromagnet 30 and the second spring 29 within the second limiting groove 28.

[0086] A cavity is formed inside the fixing ring 18, and an air outlet pipe 21 communicating with the cavity is fixedly installed at the bottom of the fixing ring 18. A collection box 22 is detachably installed at the opening of the air outlet pipe 21 away from the fixing ring 18.

[0087] Multiple second through holes 19 communicating with the cavity are formed on the fixing ring 18 along the radial direction of the motor shaft 2. Each of the multiple second through holes 19 corresponds to a multiple of the first through holes 17. Each second through hole 19 is connected to the air hole connected to the corresponding first through hole 17.

[0088] Working principle: When using this energy storage motor, the mounting bracket 3 is fixed to the body of the load switch. Starting the energy storage motor causes the motor shaft 2 to rotate, thereby compressing or stretching the energy storage spring in the load switch. This process is existing technology and will not be described in detail here.

[0089] When the energy storage motor starts, the second electromagnet 20 is synchronously activated via an existing controller or control circuit. The second electromagnet 20 is energized and forms magnetic repulsion with the magnetic block on the slip ring 9. At this time, the magnetic block drives the slip ring 9 to move away from the first heat dissipation fin 4, and the slip ring 9 drives the rotating ring 6 away from the first heat dissipation fin 4. The rotating ring 6 drives the second heat dissipation fin 7 to detach from the first heat dissipation fin 4. Simultaneously, the slider 14 on the rotating ring 6 slides along the second guide groove 16 and eventually slides into the first guide groove 15. During this process, the slip ring 9 drives the piston rods 31 of the two piston cylinders 32 to extend, and the pistons on the two piston rods 31 stretch the third spring 34 connected to them. External air enters the rodless chamber of the piston cylinder 32 through the first one-way valve 35.

[0090] When the slider 14 on the rotating ring 6 slides into the first guide groove 15, the end of the first heat dissipation fin 4 near the slip ring 9 and the end of the second heat dissipation fin 7 away from the slip ring 9 are located on the same cross-section of the motor shaft 2. At this time, under the action of the tension of the first spring 12, the first limiting block 10 slides away from the first electromagnet 13 located in the first limiting groove 11. At the same time, the first limiting block 10 drives the rotating ring 6 to rotate, and the rotating ring 6 drives the slider 14 to slide along the first guide groove 15.

[0091] When the slider 14 slides to the end of the first guide groove 15 away from the connected second guide groove 16, it abuts against the housing 1. At this time, the first spring 12 is still in a stretched state. At the same time, the rotating ring 6 drives the second heat dissipation fin 7 to be directly aligned with the corresponding first heat dissipation fin 4, and the first notch groove 5 and the second notch groove 8 form air holes and are connected to the corresponding first through hole 17 and second through hole 19.

[0092] It should be noted that the slip ring 9 is provided with a first clearance groove for the first spring 12 to extend and retract.

[0093] Next, the second electromagnet 20 is turned off, and the third electromagnet 30 is started. This process can be controlled by a controller or control circuit with control buttons, or by a sensor with a controller; these are existing technologies and will not be described in detail here.

[0094] After the third electromagnet 30 is activated, it magnetically attracts the second limiting block 27 within the second limiting groove 28. The second limiting block 27 slides closer to the third electromagnet 30 within the second limiting groove 28. During this process, the second limiting block 27 drives the annular rotating plate 25 to rotate and stretches the connected second spring 29. When the second limiting block 27 contacts the third electromagnet 30 within the second limiting groove 28, the third through hole 26 on the annular rotating plate 25 communicates with the corresponding first through hole 17.

[0095] During the rotation of the annular rotating plate 25, the third through hole 26 overlaps with the corresponding first through hole 17. At this time, under the elastic force of the fourth spring 40, the annular retaining ring 39 slides closer to the annular rotating plate 25 and finally abuts against it. During this process, the annular retaining ring 39 pushes the gas in the air chamber 24 out. The gas in the air chamber 24 is discharged sequentially through the third through hole 26, the first through hole 17, the air hole, the second through hole 19, the cavity in the fixing ring 18, the air outlet pipe 21, and the exhaust port on the collection box 22.

[0096] As the gas flows through the vents, it blows away dust and adhering substances from the vents, which are then carried by the airflow onto the filter screen 23. Afterward, the collection box 22 can be removed, and the filter screen 23 can be cleaned.

[0097] Once the energy storage operation of the energy storage motor is complete, no further cooling is required. Therefore, the third electromagnet 30 is shut down and the first electromagnet 13 is turned on. This process can be controlled by a controller or control circuit with control buttons, which is existing technology and will not be described in detail here.

[0098] After the third electromagnet 30 is turned off, under the elastic force of the second spring 29, the second limiting block 27 slides away from the third electromagnet 30 located in the second limiting groove 28 and gradually resets. During this process, the second limiting block 27 drives the annular rotating plate 25 to rotate and finally seal all the first through holes 17.

[0099] It should be noted that a second clearance groove is provided inside the housing 1 for the second spring 29 to extend and retract.

[0100] After the first electromagnet 13 is activated, it magnetically attracts the first limiting block 10 located in the first limiting groove 11. The first limiting block 10 slides closer to the first electromagnet 13 located in the first limiting groove 11 and stretches the connected first spring 12. At the same time, the first limiting block 10 drives the rotating ring 6 to rotate, and the rotating ring 6 drives the slider 14 to slide from the first guide groove 15 to the second guide groove 16. During this process, the rotating ring 6 causes the second heat dissipation fin 7 to be misaligned with the first heat dissipation fin 4.

[0101] When the first limiting block 10 contacts the first electromagnet 13 located in the first limiting groove 11, the second heat dissipation fin 7 aligns with the gap between two adjacent first heat dissipation fins 4, and the first heat dissipation fin 4 aligns with the gap between two adjacent second heat dissipation fins 7. Simultaneously, under the elastic force of the third spring 34, the piston rod 31 inside the piston cylinder 32 pulls the slip ring 9 to move closer to the first heat dissipation fin 4, and the slip ring 9 drives the rotating ring 6 to move closer to the first heat dissipation fin 4. During this process, the rotating ring 6 drives the slider 14 to slide along the second guide groove 16. At the same time, the rotating ring 6 drives the second heat dissipation fin 7 to interlock with the first heat dissipation fin 4. The second notch 8 end on the second heat dissipation fin 7 scrapes away dust and adhering substances from the two adjacent first heat dissipation fins 4, and the first notch 5 end on the first heat dissipation fin 4 scrapes away dust and adhering substances from the two adjacent second heat dissipation fins 7.

[0102] When the first heat dissipation fin 4 and the second heat dissipation fin 7 scrape against each other, most of the dust and adhering substances are pushed away from the housing 1, with a small portion remaining in the first notch groove 5 and the second notch groove 8. Cleaning is performed the next time the energy storage motor is turned on.

[0103] When the piston rod 31 inside the piston cylinder 32 pulls the slip ring 9 closer to the first heat dissipation fin 4, the piston inside the piston rod 31 pushes the gas out of the rodless chamber of the piston cylinder 32. The gas flows into the gas chamber 24 through the second one-way valve 37, the connecting pipe 36, and the airflow channel 38. At this time, the gas pushes the annular retaining ring 39 away from the annular rotating plate 25, and all the fourth springs 40 are compressed.

[0104] Finally, turn off the first electromagnet 13.

[0105] It should be noted that, to prevent gas leakage from the air chamber 24, a sealing ring is coaxially fixed within the air chamber 24. The sealing ring is located between the annular retaining ring 39 and the annular rotating plate 25. The annular rotating plate 25 is rotatably connected to the sealing ring and the housing 1. This seal is a rotational seal, which is existing technology and will not be elaborated upon here. Since the gas in the air chamber 24 does not leak, the gas entering the air chamber 24 is a gas with a certain pressure. This increases the impact force for the next cleaning of dust or adhering substances.

[0106] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
