Description

Technical Field

[0001] This utility model relates to the technical field of three-phase squirrel-cage asynchronous motors, and in particular to a low-heat-consumption three-phase squirrel-cage asynchronous motor for ultra-large air volume air pressure fans. Background Technology

[0002] The three-phase squirrel-cage asynchronous motor is a common type of motor, also known as a three-phase induction motor.

[0003] It consists of two parts: a stator and a rotor;

[0004] The purpose is to address the issue that during the use of a three-phase squirrel-cage asynchronous motor, heat tends to accumulate inside the motor, causing damage to internal components and resulting in fluctuations in the motor's operation due to heat, ultimately preventing normal use. Furthermore, the use of bolts to mount the motor can lead to loosening of these bolts over time, further impacting its normal operation.

[0005] Therefore, it is necessary to propose a new type of low-heat-consumption three-phase squirrel-cage asynchronous motor for ultra-large air volume air pressure fans. Utility Model Content

[0006] The purpose of this invention is to solve the problems of heat accumulation in motors causing heat loss and loose bolts affecting motor use, and to propose a low-heat-consumption three-phase squirrel-cage asynchronous motor for ultra-large air volume air compressor fans.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: a low-heat-consumption three-phase squirrel-cage asynchronous motor for ultra-large air volume air compressor fans, comprising a housing, a low-heat-consumption mechanism and an installation mechanism, wherein the low-heat-consumption mechanism comprises a rotating seat and a swing plate, the swing plate being connected around the surface of the rotating seat, and the rotating seat and the swing plate being used to improve the heat dissipation effect of the motor, thereby achieving the purpose of low heat dissipation of the motor.

[0008] The mounting mechanism includes an adjusting plate and a fixing cover. The upper surface of the fixing cover is fixedly connected to the lower surface of the adjusting plate. The adjusting plate and the fixing cover are used to limit the bolts used for the motor mounting to prevent the bolts from loosening. The rotation of the rotating seat can drive the swing plate and the cleaning plate to rotate, so that the cleaning plate can clean the dust on the surface of the back cover, thereby improving the heat dissipation efficiency of the motor. At the same time, the fixing cover can limit and fix the bolts used for the motor base mounting, thereby preventing the bolts from loosening during the use of the motor.

[0009] Preferably, the low-consumption mechanism further includes a cleaning plate, the front surface of which is fixedly connected to the rear surface of the swing plate. Since the cleaning plate is in contact with the heat dissipation area of ​​the rear cover, when the cleaning plate rotates, it can clean the dust accumulated on the surface of the rear cover.

[0010] Preferably, the installation mechanism further includes a storage plate, the interior of which is slidably connected to an adjustment plate. A rubber bladder is provided inside the fixing cover, and a spring is fixedly connected to the inner wall of the fixing cover. A compression plate is fixedly connected to the end of the spring away from the fixing cover, and the compression plate is in contact with the surface of the rubber bladder. By using the gas inside the rubber bladder, the part of the rubber bladder not compressed by the compression plate can expand to wrap the bolt. In conjunction with the compression plate, the bolt is squeezed and clamped, thereby preventing the bolt from loosening and affecting the normal use of the motor.

[0011] Preferably, the rear surface of the rotating seat is movably connected to a connecting seat via a bearing, the front surface of the rotating seat is provided with a first air inlet pipe, the outer surface of the rotating seat is provided with a second air inlet pipe, and the second air inlet pipe communicates with the first air inlet pipe. The rear surface of the rotating seat is provided with a first air outlet pipe, and the first air outlet pipe is located below the first air inlet pipe. The outer surface of the rotating seat is provided with a second air outlet pipe, and the second air outlet pipe is located behind the second air inlet pipe. The second air outlet pipe communicates with the first air outlet pipe. By rotating the rotating seat, internal heat can be discharged through the interior of the second air inlet pipe and the second air outlet pipe, so that the heat discharged by the motor can be diffused outward and is not easy to accumulate around the motor. In conjunction with the rotation of the swing plate, the air volume of the cooling fan can be increased.

[0012] Preferably, a base is fixedly connected to the lower surface of the housing, and a mounting rod is fixedly connected to the upper surface of the base. The rear end of the mounting rod penetrates the interior of the storage plate. A curved rod is fitted onto the side surface of the mounting rod, and the end of the curved rod away from the mounting rod is fitted onto the storage plate. The curved rod is extended into the interior of both the mounting plate and the storage plate to fix the storage plate, thereby facilitating the adjustment of the height of the storage plate.

[0013] Preferably, a stator is provided inside the housing, and a squirrel-cage rotor is fitted inside the stator. The output end of the squirrel-cage rotor extends out of the housing. A rear cover is connected to the front surface of the housing by bolts and threads, and the inner wall of the rear cover is fitted with a connecting seat. A cooling fan is fitted on the outer surface of the squirrel-cage rotor. Fitting blocks are fixedly connected to the outer surface of the squirrel-cage rotor, and the fitting blocks are fitted with the connecting seat. The fitting blocks on the outer surface of the squirrel-cage rotor can be connected to the connecting seat. When the squirrel-cage rotor rotates, it can simultaneously drive the cooling fan and the rotating seat to rotate together. The rotation of the cooling fan can extract and discharge the heat inside the housing, thereby cooling the motor.

[0014] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0015] 1. In this utility model, the connecting seat extends through the interior of the rear cover and into the interior of the outer shell. The connecting seat can be connected to the interlocking block on the outer surface of the squirrel-cage rotor. When the squirrel-cage rotor rotates, it can simultaneously drive the cooling fan and the rotating seat to rotate together. The rotation of the cooling fan can extract and discharge the heat inside the outer shell. When the heat inside the motor is discharged from the heat dissipation point inside the rear cover, some of the heat can be discharged into the interior of the rotating seat through the first air inlet pipe and the first air outlet pipe. The rotation of the rotating seat can discharge the internal heat through the interior of the second air inlet pipe and the second air outlet pipe, so that the heat discharged by the motor can be diffused outward and is not easy to accumulate around the motor. The rotation of the swing plate can increase the air volume of the cooling fan, thereby improving the heat dissipation efficiency of the motor and achieving the purpose of low heat consumption of the motor.

[0016] 2. In this utility model, the height of the storage plate can be adjusted by sliding the mounting rod and the storage plate. The adjustment plate can be pulled out from the inside of the storage plate in different directions. By moving the storage plate, the fixing cover can be moved above the bolt. The storage plate is pushed down, so that the bolt can squeeze the compression plate outward and squeeze the spring. When the compression plate is squeezed by the bolt, since the compression plate does not completely adhere to the surface of the rubber bladder, the gas in the rubber bladder can cause the part of the rubber bladder not squeezed by the compression plate to expand and wrap the bolt. With the compression and clamping of the bolt by the compression plate, the bolt can be prevented from loosening and affecting the normal use of the motor. Attached Figure Description

[0023] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0024] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0025] Please see Figure 1-5 This utility model provides a technical solution: a low-heat-consumption three-phase squirrel-cage asynchronous motor for ultra-large air volume air pressure fan, including a housing 3, a low-heat-consumption mechanism 6 and a mounting mechanism 2. The low-heat-consumption mechanism 6 includes a rotating seat 601 and a swing plate 603. The swing plate 603 is connected around the surface of the rotating seat 601. The rotating seat 601 and the swing plate 603 are used to improve the heat dissipation effect of the motor and achieve the purpose of low heat dissipation of the motor.

[0026] The mounting mechanism 2 includes an adjusting plate 202 and a fixing cover 203. The upper surface of the fixing cover 203 is fixedly connected to the lower surface of the adjusting plate 202. The adjusting plate 202 and the fixing cover 203 are used to limit the bolts used at the mounting point of the motor to prevent the bolts from loosening.

[0027] The rotation of the squirrel-cage rotor 11 drives the cooling fan 7 and the rotating base 601 to rotate together. The rotation of the rotating base 601 drives the swing plate 603 and the cleaning plate 602 to rotate, so that the cleaning plate 602 can clean the dust on the surface of the rear cover 5, thereby improving the heat dissipation efficiency of the motor. At the same time, the fixing cover 203 can limit and fix the bolts used for mounting the base 1, thereby preventing the bolts from loosening during the use of the motor.

[0028] like Figure 1 and Figure 4As shown, the low-consumption mechanism 6 also includes a cleaning plate 602, the front surface of which is fixedly connected to the rear surface of the swing plate 603.

[0029] When the swing plate 603 rotates, the swing plate 603 can drive the cleaning plate 602 to move in the same direction as the swing plate 603. Since the cleaning plate 602 is in contact with the heat dissipation area of ​​the back cover 5, when the cleaning plate 602 rotates, it can clean the dust accumulated on the surface of the back cover 5.

[0030] like Figure 1 and Figure 5 As shown, the installation mechanism 2 also includes a storage plate 201. The interior of the storage plate 201 is slidably connected to the adjustment plate 202. A rubber bladder 206 is provided inside the fixing cover 203. A spring 204 is fixedly connected to the inner wall of the fixing cover 203. A compression plate 205 is fixedly connected to the end of the spring 204 away from the fixing cover 203, and the compression plate 205 is in contact with the surface of the rubber bladder 206.

[0031] After the motor is installed using external bolts, the adjusting plate 202 can be pulled out from inside the storage plate 201 in different directions by sliding the adjusting plate 202 inside the storage plate 201. The movement of the storage plate 201 allows the fixing cover 203 to move above the bolt, pushing the storage plate 201 downwards so that the bolt can compress the compression plate 205 outwards and compress the spring 204. When the compression plate 205 is compressed by the bolt, since the compression plate 205 does not completely adhere to the surface of the rubber bladder 206, the gas inside the rubber bladder 206 can cause the area of ​​the rubber bladder 206 not compressed by the compression plate 205 to expand and wrap the bolt. With the compression and clamping of the bolt by the compression plate 205, the bolt can be prevented from loosening and affecting the normal use of the motor.

[0032] like Figure 1 and Figure 4 As shown, the rear surface of the rotating seat 601 is movably connected to the connecting seat 14 via a bearing. The front surface of the rotating seat 601 is provided with a first air inlet pipe 16. The outer surface of the rotating seat 601 is provided with a second air inlet pipe 4, and the second air inlet pipe 4 communicates with the first air inlet pipe 16. The rear surface of the rotating seat 601 is provided with a first air outlet pipe 15, and the first air outlet pipe 15 is located below the first air inlet pipe 16. The outer surface of the rotating seat 601 is provided with a second air outlet pipe 9, and the second air outlet pipe 9 is located behind the second air inlet pipe 4. The second air outlet pipe 9 communicates with the first air outlet pipe 15.

[0033] When the heat inside the motor is discharged from the heat dissipation vent inside the rear cover 5, some of the heat can pass through the first air inlet pipe 16 and the first air outlet pipe 15 into the interior of the rotating seat 601. The rotation of the rotating seat 601 can discharge the internal heat through the interior of the second air inlet pipe 4 and the second air outlet pipe 9, so that the heat discharged by the motor can be diffused outward and is not easy to accumulate around the motor. In conjunction with the rotation of the swing plate 603, the air volume of the cooling fan 7 can be increased, which can improve the heat dissipation efficiency of the motor and achieve the purpose of low heat consumption of the motor.

[0034] like Figure 1 and Figure 5 As shown, a base 1 is fixedly connected to the lower surface of the outer shell 3, and a mounting rod 12 is fixedly connected to the upper surface of the base 1. The rear end face of the mounting rod 12 penetrates the interior of the storage plate 201. A curved rod 13 is fitted and connected to the side surface of the mounting rod 12, and the end of the curved rod 13 away from the mounting rod 12 is fitted and connected to the storage plate 201.

[0035] By sliding the mounting rod 12 against the storage plate 201, the height of the storage plate 201 can be adjusted. After the height of the storage plate 201 is adjusted, the bending rod 13 can be extended into the interior of the mounting plate and the storage plate 201 respectively to fit and fix the storage plate 201, thereby facilitating the adjustment of the height of the storage plate 201.

[0036] like Figure 1-3 As shown, a stator 10 is provided inside the housing 3, and a squirrel-cage rotor 11 is fitted inside the stator 10. The output end of the squirrel-cage rotor 11 extends out of the housing 3. A rear cover 5 is connected to the front surface of the housing 3 by bolts and threads, and the inner wall of the rear cover 5 is fitted to the connecting seat 14. A cooling fan 7 is fitted on the outer surface of the squirrel-cage rotor 11. Fitting blocks 8 are fixedly connected to the outer surface of the squirrel-cage rotor 11, and the fitting blocks 8 are fitted to the connecting seat 14.

[0037] After the rear cover 5 is connected to the surface of the outer shell 3, the connecting seat 14 extends through the interior of the rear cover 5 into the interior of the outer shell 3. The fitting block 8 on the outer surface of the squirrel-cage rotor 11 can be connected to the connecting seat 14. When the squirrel-cage rotor 11 rotates, the squirrel-cage rotor 11 can simultaneously drive the cooling fan 7 and the rotating seat 601 to rotate together. The rotation of the cooling fan 7 can extract and discharge the heat inside the outer shell 3, thereby cooling the motor.

[0038] The method of use and working principle of this device: By adjusting the sliding of the plate 202 and the inside of the storage plate 201, the plate 202 can be pulled out from the inside of the storage plate 201 in different directions. By using the movement of the storage plate 201, the fixing cover 203 can be moved above the bolt. The storage plate 201 is pushed down, so that the bolt can squeeze the compression plate 205 outward and squeeze the spring 204. When the compression plate 205 is squeezed by the bolt, since the compression plate 205 does not completely adhere to the surface of the rubber bladder 206, the gas in the rubber bladder 206 can be used to expand the part of the rubber bladder 206 that is not squeezed by the compression plate 205 to wrap the bolt.

[0039] The connecting seat 14 extends through the interior of the rear cover 5 and into the interior of the outer shell 3. The connecting seat 14 can be connected to the interlocking block 8 on the outer surface of the squirrel-cage rotor 11. When the squirrel-cage rotor 11 rotates, it can simultaneously drive the cooling fan 7 and the rotating seat 601 to rotate together. The rotation of the cooling fan 7 can extract and discharge the heat inside the outer shell 3. Some of the heat can be discharged into the interior of the rotating seat 601 through the first air inlet pipe 16 and the first air outlet pipe 15. The rotation of the rotating seat 601 can discharge the internal heat through the interior of the second air inlet pipe 4 and the second air outlet pipe 9, so that the heat discharged by the motor can be diffused outward and is not easy to accumulate around the motor. Since the cleaning plate 602 is attached to the heat dissipation area of ​​the rear cover 5, when the cleaning plate 602 rotates, it can clean the dust accumulated on the surface of the rear cover 5.

[0040] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
