The motor frequency converter has the advantages of strong heat dissipation capacity and can reduce dust accumulation of internal electronic components.

[0004] The existing frequency converter used in the stirring motor does not have a dedicated fixing mechanism for buffering and reducing vibration. During the operation of the stirring motor, different degrees of vibration will be generated. If the frequency converter is directly installed on the stirring motor, the internal components of the frequency converter will be damaged to a certain extent due to long-term vibration. Summary of the invention

[0005] In view of the above-mentioned prior art, the technical problem to be solved by the utility model is that during the operation of the stirring motor, vibrations of varying degrees will be generated, and directly installing the frequency converter on the stirring motor will cause certain damage to the internal components of the frequency converter due to long-term vibration.

[0006] In order to solve the above problems, the utility model provides a stirring motor frequency converter, including a motor, a mounting base fixedly connected to the top of the motor, a frequency converter detachably connected to the top of the mounting base, three groups of telescopic rods equidistantly fixedly connected to the top of the mounting base, a baffle fixedly connected to the top of the telescopic rod, a vibration-damping spring sleeved on the surface of the motor, and the two ends of the vibration-damping spring are respectively fixedly connected to the mounting base and the baffle, a first thread groove is chiseled on the top of the baffle, a bottom end of the frequency converter is fixedly connected to a bottom plate, a second thread groove corresponding to the first thread groove is symmetrically chiseled on the bottom plate, and the second thread groove is fixed to a clamping block by bolt threads, a clamping block is fixedly connected to the top of a middle group of baffles, a clamping groove corresponding to the clamping block is chiseled on the bottom plate located between the two groups of second thread grooves, and the clamping block is engaged with the clamping groove.

[0007] In the above-mentioned stirring motor inverter, the vibration of the inverter can be effectively reduced when the motor is in use, thereby extending the service life.

[0008] As a further improvement of the present application, a protective cover is rotatably connected to the side of the base plate via a first rotating shaft, and the protective cover covers the surface of the inverter.

[0009] As a further improvement of the present application, heat dissipation grooves are drilled at both ends of the protective cover, and the two heat dissipation grooves are staggered with each other.

[0010] As a further improvement of the present application, the inner walls on both sides of the protective cover are connected with screws for vertical symmetrical rotation, and a sealing plate is provided on the screw through a clamping sleeve, and the cross-section of the sealing plate is larger than the cross-section of the heat dissipation groove.

[0011] As another improvement of the present application, first belt pulleys are symmetrically mounted on the two lead screws, and the two first belt pulleys are connected by a first belt. A second rotating shaft is symmetrically rotatably connected to the middle portion of the side wall of the protective cover between the two lead screws.

[0012] As another improved supplement of the present application, a second belt pulley is sleeved on the second rotating shaft on the side of the lead screw away from the first belt pulley, and the two second belt pulleys are connected by a second belt.

[0013] As another improved supplement of the present application, gears are sleeved on the two second rotating shafts near the side walls of the protective cover, and the two gears are meshed and connected, and a turntable is fixedly connected to one of the second rotating shafts located outside the protective cover.

[0014] In summary, this solution can be achieved. When the inverter is installed on the motor, the slot at the bottom of the base plate can be placed on the block, so that the second thread groove can be quickly aligned with the first thread groove. At this time, the second thread groove and the first thread groove are fixed in sequence by bolts to complete the rapid installation of the inverter. Since the base plate is much larger than the bottom cross-section of the inverter and multiple sets of shock-absorbing springs and telescopic rods are used, the stability of the inverter installed on the motor can be ensured. During the use of the motor, large vibrations will be generated. At this time, the shock-absorbing springs and telescopic rods can be used to buffer and reduce vibration of the upper inverter, thereby reducing damage to the internal electronic components of the inverter, effectively achieving the effect of reducing the vibration of the inverter when the motor is used and extending the service life.

DETAILED DESCRIPTION

[0024] Two implementation modes of the present application are described in detail below with reference to the accompanying drawings.

[0025] The first implementation method:

[0026] Figure 1-5 A frequency converter for a stirring motor is shown, comprising a motor 1, a mounting base 2 being fixedly connected to the top of the motor 1, a frequency converter 5 being detachably connected to the top of the mounting base 2, three groups of telescopic rods 6 being equidistantly fixedly connected to the top of the mounting base 2, a baffle 11 being fixedly connected to the top of the telescopic rod 6, a damping spring 3 being sleeved on the surface of the motor 1, and two ends of the damping spring 3 being fixedly connected to the mounting base 2 and the baffle 11 respectively, a first thread groove 12 being chiseled at the top of the baffle 11, a bottom plate 7 being fixedly connected to the bottom end of the frequency converter 5, a second thread groove 14 corresponding to the first thread groove 12 being symmetrically chiseled on the bottom plate 7, and the second thread groove 14 being fixedly fixed to a clamping block 13 by bolt threads, a clamping block 13 being fixedly connected to the top of a group of baffles 11 in the middle, a clamping groove 15 corresponding to the clamping block 13 being chiseled on the bottom plate 7 located between the two groups of second thread grooves 14, and the clamping block 13 is engaged with the clamping groove 15.

[0027] This solution can be achieved. When the inverter 5 is installed on the motor 1, the slot 15 at the bottom end of the base plate 7 can be stuck on the block 13, so that the second thread groove 14 can be quickly aligned with the first thread groove 12. At this time, the second thread groove 14 and the first thread groove 12 are fixed in sequence by bolts, thereby completing the rapid installation of the inverter 5. Since the base plate 7 is much larger than the bottom cross-section of the inverter 5, and multiple sets of vibration-damping springs 3 and telescopic rods 6 are used, the stability of the inverter 5 installed on the motor 1 can be ensured. During the use of the motor 1, a large vibration will be generated. At this time, the vibration-damping springs 3 and the telescopic rods 6 can be used to buffer and reduce the vibration of the upper inverter 5, thereby reducing the damage to the internal electronic components of the inverter 5, effectively achieving the effect of reducing the vibration of the inverter 5 when using the motor 1 and extending the service life.

[0028] The second implementation method:

[0029] Figure 1-2 and Figure 6-7It is shown that the side of the bottom plate 7 is rotatably connected to the protective cover 4 through the first rotating shaft, and the protective cover 4 covers the surface of the inverter 5. Heat dissipation grooves 8 are drilled at both ends of the protective cover 4, and the two heat dissipation grooves 8 are staggered. The inner walls on both sides of the protective cover 4 are symmetrically connected to the upper and lower inner walls. A sealing plate 16 is sleeved on the screw 17 through a sleeve 18, and the cross-section of the sealing plate 16 is larger than the cross-section of the heat dissipation groove 8. The two screws 17 are symmetrically sleeved with first belt pulleys 19, and the two first belt pulleys 19 are connected by a first belt 20. The middle part of the side wall of the protective cover 4 between the two screws 17 is symmetrically connected to the second rotating shaft. The side of the screw 17 away from the first belt pulley 19 is sleeved with a second belt pulley 21 on the second rotating shaft, and the two second belt pulleys 21 are connected by a second belt 22. The two second rotating shafts are sleeved with gears 10 near the side wall of the protective cover 4, and the two gears 10 are meshed and connected. A turntable 9 is fixedly connected to one of the second rotating shafts outside the protective cover 4.

[0030] This solution can achieve that when the frequency converter 5 generates heat during use, the turntable 9 can be rotated, and the two second shafts can be driven to rotate in the opposite direction through the two gears 10, and then the upper lead screw 17 can be driven to rotate through the second belt pulley 21 and the second belt 22, and then the lower lead screw 17 can be driven to rotate simultaneously through the first belt pulley 19 and the first belt 20, so that the sealing plates 16 on both sides can be moved horizontally in the same direction, and the heat dissipation slots 8 can be opened for heat dissipation, and can be closed when not in use to prevent mice from entering the protective cover 4 to damage the frequency converter 5, so that the protective cover 4 acts as a protective group for the frequency converter 5, effectively achieving the effect of protecting the frequency converter 5 without affecting the heat dissipation function.

[0031] In view of current practical needs, the protection scope of the above-mentioned implementation mode adopted in this application is not limited to this. Various changes made within the knowledge scope of technical personnel in this field without departing from the concept of this application still fall within the protection scope of this utility model.
