A fully enclosed motor ventilation structure

Abstract

This utility model discloses a fully enclosed motor ventilation structure, relating to the field of motor technology. It includes a motor housing, with a limiting sleeve rotatably connected to one end of the housing. In this utility model, when the motor is running, the two motor shafts rotate synchronously, thereby driving the limiting sleeve and multiple fan blades to rotate. Airflow is blown in from the outside through three filter plates. The filter plates perform preliminary filtration of the airflow. Part of the airflow passes through an annular filter screen and flows between the heat dissipation fins, accelerating the heat dissipation of the motor housing by the heat dissipation fins. Another part of the airflow passes through multiple filter plates and enters the interior of the motor housing. The airflow carries away heat through the gap between the stator and rotor and flows to the outside through a retaining plate, effectively guiding the heat inside the motor housing. Furthermore, the hot air is discharged upwards through the casing without being blocked by connected equipment, allowing heat to be effectively guided to the outside, improving the overall heat dissipation effect. It also effectively blocks impurities when the motor is not in use, facilitating operation.

Description

Technical Field

[0001] This utility model relates to the field of motor technology, specifically to a fully enclosed motor ventilation structure. Background Technology

[0002] A fully enclosed motor ventilation structure is a cleverly designed structure that achieves heat dissipation while ensuring good motor protection performance. The fully enclosed motor incorporates a labyrinth seal between the end cover and the rotor pressure ring, ensuring both internal sealing and allowing cooling air to pass through, thus preventing abnormal motor operation.

[0003] Some existing fully enclosed motors have independent air ducts for the stator and rotor, and use axial fans to introduce external air for heat dissipation instead of internal air circulation. However, the air output effect of multiple air ducts is limited, resulting in poor heat dissipation. Furthermore, the air ducts make the airflow parallel to the motor shaft, and the airflow will blow to the connecting shaft and the vicinity of the connected equipment, causing obstruction. This results in higher temperatures near the motor casing, making it inconvenient to use. Utility Model Content

[0008] The control module is located inside the chassis and is used to protect the top of the card plate.

[0009] Furthermore, the control module includes a second card plate, and the top of the second card plate is provided with multiple docking slots at equal intervals.

[0010] Furthermore, a positioning groove is provided on the outer wall of the second card plate, an insert rod is slidably connected inside the chassis, a rotating rod is provided inside the chassis, one end of the rotating rod is rotatably connected to the insert rod, the other end of the rotating rod passes through the chassis and extends to its outside, a docking ring is fixedly sleeved on the outer wall of the rotating rod, and the docking ring is screwed into the chassis.

[0011] Furthermore, multiple slots are equidistantly provided on the inner wall of the positioning groove, and the insertion rod can be movably engaged with adjacent slots.

[0012] Furthermore, a protective shell is movably snapped onto one end of the motor housing, and a filter plate is fixedly embedded in one end of the protective shell.

[0013] Furthermore, an annular filter screen is fixedly connected to the inner wall of the protective shell, and a positioning ring is fixedly sleeved on the outer wall of the motor housing, the positioning ring being able to movably engage with the annular filter screen.

A fixing screw is screwed onto the outer wall of the ear plate, and the fixing screw can pass through the ear plate and screw into it.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] When the motor is running, the two motor shafts rotate synchronously, thereby driving the limit sleeve and multiple fan blades to rotate. Airflow is blown in from the outside through the three filter plates. The three filter plates perform preliminary filtration of the airflow. Part of the airflow passes through the annular filter screen and flows between the heat dissipation fins, accelerating the heat dissipation of the heat dissipation fins on the motor housing. The other part of the airflow passes through multiple filter plates and enters the inside of the motor housing. The airflow carries away the heat through the gap between the stator and rotor, and flows to the outside through the clamping plate. This effectively guides the heat inside the motor housing, improving the heat dissipation effect. In addition, the hot air is discharged upward through the casing without being blocked by the connected equipment, so that the heat can be effectively guided to the outside, improving the overall heat dissipation effect. Furthermore, it can effectively block impurities when the motor is not in use, making it convenient to use. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-6 This utility model provides a technical solution: a fully enclosed motor ventilation structure, including a motor housing 10, one end of which is rotatably connected to a limiting sleeve 11, and a plurality of fan blades 111 and filter plates 112 are fixedly connected at equal intervals on one side of the limiting sleeve 11. A plurality of heat dissipation fins 101 are fixedly connected to the outside of the motor housing 10; a chassis 12, fixedly connected to the outside of the motor housing 10, and a clamping plate 121 is fixedly connected to the top of the chassis 12. A plurality of filter screens 122 are fixedly connected to the top of the clamping plate 121 at equal intervals; and a control module 13, disposed inside the chassis 12, which is used to protect the top of the clamping plate 121.

[0026] In specific implementation, when installing the protective shell 14, the annular filter 141 is aligned with the positioning ring 143 and snapped in place, so that the ear plate 144 and ear plate 145 are aligned with each other. Then, the two fixing screws 146 are tightened to quickly and stably limit the protective shell 14. When the motor is running, the two motor shafts rotate synchronously, thereby driving the limiting sleeve 11 and multiple fan blades 111 to rotate. Airflow is blown in from the outside through the filter plate 142. The filter plate 142 performs preliminary filtration of the airflow. Part of the airflow passes through the annular filter 141 and flows between the heat dissipation fins 101, thereby accelerating the heat dissipation of the heat dissipation fins 101 on the motor shell 10. Another part of the airflow passes through multiple filter plates 112 and enters the interior of the motor shell 10, guiding the heat of the stator and rotor. The airflow carries away the heat through the gap between the stator and rotor and flows to the outside through the clamping plate 121, effectively guiding the heat inside the motor shell 10, thereby accelerating the overall heat dissipation of the motor and improving the heat dissipation effect.

[0027] See Figure 4-5The control module 13 includes a second card plate 131, and the top of the second card plate 131 is provided with multiple docking slots 132 at equal intervals.

[0028] A positioning groove 133 is provided on the outer wall of the card plate 131. A plug rod 134 is slidably connected inside the chassis 12. A rotating rod 135 is provided inside the chassis 12. One end of the rotating rod 135 is rotatably connected to the plug rod 134. The other end of the rotating rod 135 passes through the chassis 12 and extends to its outside. A docking ring 136 is fixedly sleeved on the outer wall of the rotating rod 135. The docking ring 136 is screwed into the chassis 12.

[0029] Multiple slots 1331 are equidistantly provided on the inner wall of the positioning groove 133, and the insertion rod 134 can be movably engaged with the adjacent slots 1331.

[0030] In practice, when installing the second clamping plate 131, it is aligned with the top of the housing 12. Then, the rotating rod 135 is manually rotated from the outside to drive the insertion rod 134 to move, so that the insertion rod 134 is engaged in the positioning groove 133, thereby limiting the rotation of the second clamping plate 131. After the second clamping plate 131 is rotated so that the multiple docking grooves 132 are aligned with the second filter screen 122, the two motor shafts rotate synchronously when the motor is running, thereby driving the limiting sleeve 11 and multiple fan blades 111 to rotate, and airflow is blown in from the outside through the third filter plate 142. The filter plate 142 performs preliminary filtration of the airflow. Part of the airflow passes through the annular filter 141 and flows between the heat dissipation fins 101, thereby accelerating the heat dissipation of the motor housing 10 by the heat dissipation fins 101. Another part of the airflow passes through multiple filter plates 112 and enters the interior of the motor housing 10, guiding the heat of the stator and rotor. The airflow carries away the heat through the gap between the stator and rotor and flows to the outside through the clamping plate 121, effectively guiding the interior of the motor housing 10, thereby accelerating the overall heat dissipation of the motor and improving the heat dissipation effect.

[0031] See Figure 6 One end of the motor housing 10 is movably snapped with a protective shell 14, and one end of the protective shell 14 is fixedly embedded with a filter plate 142.

[0032] An annular filter screen 141 is fixedly connected to the inner wall of the protective shell 14, and a positioning ring 143 is fixedly sleeved on the outer wall of the motor shell 10. The positioning ring 143 can be movably engaged with the annular filter screen 141.

[0033] Two ear plates 144 are symmetrically fixed to one end of the protective shell 14, and two ear plates 145 are symmetrically fixed to the outer wall of the motor housing 10. A fixing screw 146 is screwed onto the outer wall of the ear plate 144, and the fixing screw 146 can pass through the ear plate 145 and screw onto it.

[0034] In practice, the protective shell 14 shields and protects the multiple rotating fan blades 111, and the annular filter 141 performs preliminary filtration of the incoming airflow. The annular filter 141 can prevent impurities from entering the interior of the protective shell 14 when the limiting sleeve 11 is not rotating. When installing the protective shell 14, the annular filter 141 is aligned with the positioning ring 143 and snapped in place, so that the ear plate 144 and the ear plate 145 are aligned with each other. Then, the two fixing screws 146 are tightened to quickly and stably limit the protective shell 14.

[0035] Working principle: When installing the protective shell 14, the annular filter 141 is aligned with the positioning ring 143 and snapped in place, so that the ear plate 144 and ear plate 145 are aligned with each other. Then, the two fixing screws 146 are tightened to quickly and stably limit the protective shell 14. When the motor is running, the two motor shafts rotate synchronously, thereby driving the limiting sleeve 11 and multiple fan blades 111 to rotate. Airflow is blown in from the outside through the filter plate 142. The filter plate 142 performs preliminary filtration of the airflow. Part of the airflow passes through the annular filter 141 and flows between the heat dissipation fins 101, thereby accelerating the heat dissipation of the heat dissipation fins 101 on the motor shell 10. Another part of the airflow passes through multiple filter plates 112 and enters the interior of the motor shell 10, guiding the heat of the stator and rotor. The airflow carries away the heat through the gap between the stator and rotor and flows to the outside through the clamping plate 121, effectively guiding the heat inside the motor shell 10, thereby accelerating the overall heat dissipation of the motor and improving the heat dissipation effect.
