Description

Technical Field

[0001] The utility model relates to the technical field of three-phase asynchronous motors, in particular to a quick-detachable three-phase asynchronous motor. Background Art

[0002] The three-phase asynchronous motor is a type of induction motor that is powered by a 380V three-phase AC current. Since the rotor and stator rotating magnetic field of the three-phase asynchronous motor rotate in the same direction but at different speeds, there is a slip, so it is called a three-phase asynchronous motor. The speed of the rotor of the three-phase asynchronous motor is lower than the speed of the rotating magnetic field. The rotor winding generates electromotive force and current due to the relative motion between the rotor winding and the magnetic field, and interacts with the magnetic field to generate electromagnetic torque, realizing energy conversion.

[0003] In the "A Stable Three-Phase Asynchronous Motor" with the patent publication CN219833926U, the motor body is used to rotate and output power to drive the mechanical structure to operate. The protective module is sleeved on one side of the motor body to protect the motor body in a humid environment and maintain the stability of the motor body in a humid environment. The protective module includes a base plate arranged at the bottom end of the motor body, a sleeve sleeved on one side of the motor body and fixedly connected to the bottom plate at the bottom end, an air inlet duct fixed to one side of the sleeve and connected to the sleeve, a high-speed fan installed on the inner wall of the sleeve, a heating ring installed on the outer surface of the air inlet duct and extending into the inner cavity of the air inlet duct, a filter fixed on the inner wall of the air inlet duct, an electric telescopic rod symmetrically installed on the outer surface of the sleeve, and a sealing cover fixed on the end of the electric telescopic rod. The stable three-phase asynchronous motor has the advantages of stable starting and operation in a humid environment;

[0004] The existing three-phase asynchronous motors are basically connected by screws when assembled and installed. However, this connection method will cause the screws to loosen due to vibration during the later use of the motor, and the screws are prone to rust. It is not convenient to quickly disassemble and separate the three-phase asynchronous motor in the later stage, which will affect the stable use of the three-phase asynchronous motor in the later stage.

[0005] Therefore, we proposed a quick-disassembly three-phase asynchronous motor that can solve the above problems well. Utility Model Content

[0006] The purpose of the utility model is to provide a quick-disassembly three-phase asynchronous motor to solve the problem raised in the above background technology that the existing three-phase asynchronous motors on the market are basically connected by screws when assembled and installed, but this connection method will cause the connecting screws to loosen due to vibration during the later use of the motor, and the screws are prone to rust, which is not convenient for the rapid disassembly and separation operations of the three-phase asynchronous motor in the later period, and will affect the stable use of the three-phase asynchronous motor in the later period.

[0007] To achieve the above object, the present invention provides the following technical solution: a quick-detachable three-phase asynchronous motor, comprising a base, a slot being provided on the top of the base, and a protective shell being mounted in the slot;

[0008] It also includes: a motor body, an output shaft is installed through the internal slotted bearing, and the outer end of the output shaft extends to the outside of the motor body, and both ends of the interior of the base are slotted with a disassembly mechanism, which can use the disassembly mechanism to automatically pop out the pull rod into the limit slot through elastic action, so that the protective shell and the base can be quickly assembled.

[0009] Preferably, the disassembly and assembly mechanism includes pull rods, wherein the four pull rods are slidably installed at the inner two ends of the base, and the structures of the four pull rods are identical, and the inner ends of the four pull rods extend through the four limit grooves, and the four limit grooves are opened on the outside of the two ends of the protective shell. The disassembly and assembly mechanism also includes tension springs, wherein the four tension springs are all wrapped and connected to the outside of the four pull rods, and the outsides of the four tension springs are connected to the inner wall of the base. The four pull rods can be automatically popped out into the four limit grooves by the elastic force of the four tension springs themselves. At this time, the motor body can be quickly assembled, which saves time and effort.

[0010] Preferably, a protective shell is installed on the outside of the motor body, and the diameter of the protective shell is larger than the diameter of the motor body, and the outer end of the motor body extends through to the outside of the protective shell. The motor body can be protected by the protective shell to prevent the motor body from being deformed and damaged due to extrusion and collision.

[0011] Preferably, shock-absorbing plates are installed on both sides of the interior of the protective shell by screws, and the two shock-absorbing plates are semicircular in shape, and the inner sides of the two shock-absorbing plates are fitly connected to the outer wall of the motor body. A layer of sound-absorbing holes is opened inside the two shock-absorbing plates, and the two layers of sound-absorbing holes are symmetrically arranged about the vertical center line of the protective shell, and the inner sides of the two layers of sound-absorbing holes are fitly connected to the outer wall of the motor body. The noise generated by the operation of the motor body can be reduced and absorbed through the two layers of sound-absorbing holes.

[0012] Preferably, a circle of sound-absorbing sponge rods is installed on the internal screws of the protective shell, and the sound-absorbing sponge rods are arranged at equal intervals, and the inner side of the sound-absorbing sponge rods is fitly connected to the outer walls of the two shock-absorbing plates. The noise absorbed by the two layers of sound-absorbing holes can be optimized and reduced by the sound-absorbing sponge rods to prevent the noise from being transmitted to the outside of the motor body and affecting the hearing system of the staff.

[0013] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0014] A protective shell is connected by slotting through a slot on the top of the base, and then pull rods are slidably installed through slots on both sides of the base. The inner ends of the four pull rods are extended into the limit slots opened at both ends of the protective shell. At this time, the position of the motor body after installation can be limited and fixed, avoiding the loosening of the motor body due to vibration during use, thereby improving the stability of the motor body.

[0015] Furthermore, tension springs are provided at both ends of the inner portion of the base, and then pull rods are wound around the inner sides of the four tension springs. The four pull rods can be pulled to move the position at a later stage, and the protective shell can be separated from the base. Subsequently, the protective shell and the base can be quickly disassembled and separated. Finally, the elastic force of the four tension springs can be used to elastically reset the positions of the four pull rods after being pulled, making the operation more time-saving and labor-saving.

[0016] By installing a protective shell on the outside of the motor body, the motor body can be protected by the protective shell to prevent deformation and damage of the motor body due to extrusion and collision during use, thereby increasing the overall service life of the motor body.

[0017] Furthermore, two inclined damping plates are attached to the outside of the motor body, and a layer of sound-absorbing holes is opened inside each of the two damping plates. The sound-absorbing holes and the two damping plates can reduce the vibration noise generated by the motor body during operation, thereby improving the use efficiency of the motor body.

[0018] A circle of sound-absorbing sponge rods is set on the inner side of the protective shell, and the outer sides of the circle of sound-absorbing sponge rods are fitted and connected to the shock-absorbing plate. The circle of sound-absorbing sponge rods can be used to prevent the noise of the motor from being transmitted, thereby achieving the effect of noise reduction, making it more convenient to use the motor body in the later stage, and avoiding the noise from being transmitted to the outside of the motor body and affecting the hearing system of the staff.

[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] This utility provides the following technical solutions:

[0028] Embodiment 1, in order to solve the problem of cumbersome screw disassembly and assembly in existing three-phase asynchronous motors, discloses:

[0029] The base 3 has an empty slot on its top, and the protective shell 2 is mounted inside the empty slot;

[0030] It also includes: a motor body 1, an output shaft 4 is installed through the internal slotted bearing, and the outer end of the output shaft 4 extends to the outside of the motor body 1, and both ends of the interior of the base 3 are slotted and provided with a disassembly mechanism, which can use the disassembly mechanism to automatically pop out the pull rod 6 into the limit groove 7 through elastic action, so that the protective shell 2 and the base 3 can be quickly assembled.

[0031] The disassembly and assembly mechanism includes a pull rod 6, wherein the four pull rods 6 are slidably installed at the inner two ends of the base 3, and the structures of the four pull rods 6 are identical, and the inner ends of the four pull rods 6 extend into the four limit grooves 7, and the four limit grooves 7 are all opened on the outside of the two ends of the protective shell 2. The disassembly and assembly mechanism also includes a tension spring 8, wherein the four tension springs 8 are all wrapped and connected to the outside of the four pull rods 6, and the outsides of the four tension springs 8 are all connected to the inner wall of the base 3.

[0032] like Figure 1-Figure 3 As shown, when the motor body 1 needs to be assembled and installed, the four pull rods 6 are pulled to move the position. At this time, the protective shell 2 is placed in the empty slot opened above the inside of the motor body 1, and then the four pull rods 6 are released. At this time, the four tension springs 8 will elastically reset the positions of the four pulled pull rods 6 through their own elastic force, so that the four pull rods 6 can be automatically popped out into the limit slots 7 opened at both ends of the protective shell 2. Then, the motor body 1 can be quickly assembled and installed, avoiding the phenomenon that the traditional motor body 1 is easily loosened and unstable when installed by screws.

[0033] Embodiment 2 is different from embodiment 1 in that the motor body 1 can be protected by the protective shell 2 when the three-phase asynchronous motor is in use, thereby increasing the service life of the motor body 1.

[0034] A protective shell 2 is installed on the outside of the motor body 1 . The diameter of the protective shell 2 is larger than the diameter of the motor body 1 , and the outer end of the motor body 1 extends through the protective shell 2 to the outside.

[0035] like Figure 1 and Figure 4 As shown, when the motor body 1 is working, the protective shell 2 installed on the outside thereof can protect the working motor body 1, preventing the motor body 1 from being deformed and damaged due to squeezing and collision, thereby increasing the overall service life of the motor body 1.

[0036] Embodiment 3 is different from embodiment 1 in that the vibration generated by the three-phase asynchronous motor during operation can also be subjected to noise reduction treatment, and discloses:

[0037] Shock-absorbing plates 5 are installed on both sides of the interior of the protective shell 2 by screws, and the two shock-absorbing plates 5 are semicircular in shape, and the inner sides of the two shock-absorbing plates 5 are fitly connected to the outer wall of the motor body 1.

A circle of sound-absorbing sponge rods 9 are installed with screws inside the protective shell 2, and the circle of sound-absorbing sponge rods 9 are arranged at equal intervals, and the inner side of the circle of sound-absorbing sponge rods 9 is fitly connected to the outer walls of the two shock-absorbing plates 5.

[0038] like Figures 1-6 As shown, when the motor body 1 generates vibration during operation, the shock-absorbing plates 5 connected on both sides thereof will reduce and absorb the generated vibration through the two layers of sound-absorbing holes 10 to prevent the noise from being transmitted to the outside of the motor body 1, and then a circle of sound-absorbing sponge rods 9 will be used to further reduce the noise absorbed by the two layers of sound-absorbing holes 10, thereby achieving the effect of noise reduction and preventing the noise from being transmitted to the outside of the motor body 1 and affecting the hearing system of the staff.
