Description

Technical Field

[0001] This utility model relates to the field of vibration motor technology, and in particular to an explosion-proof three-phase asynchronous vibration motor with multiple sealing structures. Background Technology

[0002] An explosion-proof three-phase asynchronous vibratory motor is a type of vibratory motor that can operate safely in explosive gas environments. The working principle of the explosion-proof three-phase asynchronous vibratory motor is similar to that of an ordinary three-phase asynchronous motor. When three-phase AC power is applied to the stator windings of the motor, a rotating magnetic field is generated. This magnetic field acts on the rotor windings, causing the rotor to generate an induced current, which in turn causes it to rotate under the action of electromagnetic force. At the same time, each end of the motor rotor has a set of eccentric wheels. When the rotor rotates, the centrifugal force generated by the eccentric wheels causes the motor to vibrate, thereby providing vibration force for the vibrating machinery.

[0003] When a three-phase asynchronous vibratory motor is used in a dusty environment, dust can easily enter the motor from the main shaft due to the motor's generally poor sealing. Since the motor's internal temperature is high when it is running, there is a risk of explosion. Therefore, improvements are urgently needed.

[0004] The existing patent (publication number: CN220605645U) discloses a dust explosion-proof three-phase asynchronous vibratory motor, including a vibratory motor body, a main shaft, an eccentric block, a dust cover, and bearing seats. The bearing seats are installed at both ends of the vibratory motor body, and bearing bodies are installed inside the bearing seats. A dustproof ring groove is provided on the outer wall of one side of the bearing seat. The main shaft is installed inside the vibratory motor body, and the eccentric block is installed at both ends of the main shaft. The dust cover is fixed on the outer wall of the main shaft on one side of the eccentric block, and one side of the dust cover extends into the interior of the dustproof ring groove. Protective covers are installed at both ends of the vibratory motor body by bolts, and a first sealing ring is adhered to the end of the protective cover near the vibratory motor body. A second sealing ring is adhered to the surface of the vibratory motor body at the position of the first sealing ring. This achieves the effect of dust explosion prevention, making it safer, improving the convenience of disassembly and assembly, and also improving the noise reduction effect and reducing noise pollution.

[0005] To address the aforementioned issues, existing patents offer solutions. However, while existing explosion-proof three-phase asynchronous vibratory motors have multiple sealing structures for their internal components and wiring harnesses, making their internal structure relatively safe, their external connecting cables and metal fasteners are exposed during installation. This results in the lack of a sealed and isolated structure for the connecting cables and metal fasteners, making them susceptible to external influences during use. Consequently, the explosion-proof three-phase asynchronous vibratory motor may malfunction, thus hindering user operation.

[0006] To address this, an explosion-proof three-phase asynchronous vibration motor with a multi-layered sealing structure is proposed. Utility Model Content

[0028] 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.

[0029] Please see Figure 1-5 An explosion-proof three-phase asynchronous vibratory motor with a multi-seal structure includes an explosion-proof three-phase asynchronous vibratory motor body 1, a cable carrier box 2 at the bottom of the explosion-proof three-phase asynchronous vibratory motor body 1, and an auxiliary mechanism 3 on the outside of the explosion-proof three-phase asynchronous vibratory motor body 1. The auxiliary mechanism 3 includes a bearing component 301 and a protective component 302. The bearing component 301 is located at the bottom of the explosion-proof three-phase asynchronous vibratory motor body 1, and the protective component 302 is located on both sides of the explosion-proof three-phase asynchronous vibratory motor body 1.

[0030] The load-bearing assembly 301 includes a load-bearing base 301a, a protective channel 301b, a protective hose 301c, an impact-resistant housing 301d, and a limiting support rod 301e. The load-bearing base 301a is located at the bottom of the explosion-proof three-phase asynchronous vibration motor body 1. The protective channel 301b is bolted to the top of the load-bearing base 301a. The protective hose 301c is snapped onto the outside of the cable. The impact-resistant housing 301d is bolted to the top of the protective channel 301b. The limiting support rod 301e is fixedly connected to the inside of the impact-resistant housing 301d.

[0031] In this embodiment: by setting up a support base 301a, a protective channel 301b, a protective hose 301c, an impact-resistant housing 301d, and a limiting support rod 301e, when using this explosion-proof three-phase asynchronous vibration motor with a multi-seal structure, the user can pass the cable extending from inside the cable carrier box 2 through the protective hose 301c, so that it can provide a first layer of sealing protection for the cable. Then, the impact-resistant housing 301d is combined with the protective hose 301c. At the same time, the limiting support rod 301e set inside the impact-resistant housing 301d can prevent the protective hose 301c from contacting the inside of the impact-resistant housing 301d, thereby achieving double sealing protection. Then, the impact-resistant housing 301d is combined with the protective channel 301b and the support base 301a, so that the support base 301a can support the protective channel 301b, the protective hose 301c, the impact-resistant housing 301d, the limiting support rod 301e, and the cable. Moreover, the cable can be connected inside the relatively spacious protective channel 301b, which can also provide sealing protection.

[0032] Specifically, such as Figure 2 , Figure 4 As shown, the protective component 302 includes a fixed rod 302a fixedly connected to both sides of the explosion-proof three-phase asynchronous vibration motor body 1, and a bearing rod 302b rotatably connected to the bottom of the fixed rod 302a.

[0033] Specifically, such as Figure 2 , Figure 4 As shown, a sealing protective cylinder 302c is slidably connected to the surface of the bearing rod 302b. A sealing ring is snapped into the top of the sealing protective cylinder 302c, and a reinforcing rod 302d is provided at the bottom of the sealing protective cylinder 302c. The top of the reinforcing rod 302d is fixedly connected to the bottom of the bearing rod 302b.

[0034] Specifically, such as Figure 2 , Figure 4 As shown, the inner side of the reinforcing rod 302d is threaded with a positioning rod 302e, and the top of the positioning rod 302e is rotatably connected to the bottom of the sealing protective cylinder 302c.

[0035] In this embodiment: by setting a fixed rod 302a, a bearing rod 302b, a sealing protective cylinder 302c, a reinforcing rod 302d, and a positioning rod 302e, after the explosion-proof three-phase asynchronous vibration motor body 1 is installed, the user can rotate the bearing rod 302b, which is fixed at the bottom of the fixed rod 302a, back to the position facing the explosion-proof three-phase asynchronous vibration motor body 1. This ensures that the sealing protective cylinder 302c, the reinforcing rod 302d, and the positioning rod 302e, which are carried by the bearing rod 302b, are in a vertical position with the metal connectors used for installing the explosion-proof three-phase asynchronous vibration motor body 1. Then, the user can rotate the positioning rod 302e. Under the action of the thread, the positioning rod 302e can drive the sealing protective cylinder 302c to move upward, thereby enabling it to perform sealing and protection treatment on the metal connectors.

[0036] Specifically, such as Figure 5 As shown, the bottom of the explosion-proof three-phase asynchronous vibration motor body 1 is provided with an auxiliary component 4. The auxiliary component 4 includes a sealing channel 401 that is snapped onto the outside of the positioning rod 302e. The bottom of the sealing channel 401 is threaded with a sealing cap 402.

[0037] Specifically, such as Figure 5 As shown, a contact block 403 is fixedly connected to the top of the sealing channel 401, and the top of the contact block 403 contacts the bottom of the sealing protective cylinder 302c.

[0038] In this embodiment: by setting a sealing channel 401, a sealing cap 402 and a contact block 403, the sealing channel 401, the sealing cap 402 and the contact block 403 cooperate with each other to protect and seal the rotating structure inside the protective assembly 302.

[0039] Specifically, such as Figure 3 As shown, the outer perimeter of the support base 301a is arc-shaped, and the protective channel 301b is cylindrical in shape.

[0040] Specifically, such as Figure 3 As shown, the top of the protective channel 301b is threaded to the bottom of the protective hose 301c, the surface of the protective hose 301c is in contact with the surface of the limiting support rod 301e, and the outer side of the protective hose 301c is close to the inner side of the impact-resistant housing 301d.

[0041] In this embodiment: by setting up a support base 301a, a protective channel 301b, and a protective hose 301c, the support base 301a, the protective channel 301b, and the protective hose 301c cooperate with each other to seal and protect the cable extending from the cable carrier box 2.

[0042] Specifically, such as Figure 4As shown, the surface of the sealing and protective cylinder 302c is in the shape of an inverted bell, and the bottom of the sealing and protective cylinder 302c is a cylindrical handle.

[0043] Specifically, such as Figure 4 As shown, a rotating handle is fixedly connected to the bottom of the positioning rod 302e, and the top of the positioning rod 302e is in the shape of a disc.

[0044] In this embodiment: by setting a sealing protective cylinder 302c and a positioning rod 302e, the sealing protective cylinder 302c and the positioning rod 302e cooperate with each other to seal and protect the metal connecting parts used during the installation of the explosion-proof three-phase asynchronous vibration motor body 1.

[0045] Working principle: First, when protecting the explosion-proof three-phase asynchronous vibratory motor body 1, the user can pass the cable extending from the cable carrier box 2 through the protective hose 301c, providing a first layer of sealing protection for the cable. Then, the impact-resistant housing 301d is combined with the protective hose 301c. Simultaneously, the limiting support rod 301e inside the impact-resistant housing 301d prevents the protective hose 301c from contacting the inside of the impact-resistant housing 301d, thus achieving double sealing protection. Finally, the impact-resistant housing 301d is combined with the protective channel 301b and the support base 301a, allowing the support base 301a to support the protective channel 301b, the protective hose 301c, and the impact-resistant housing 301d. The limit support rod 301e and the cable, and the cable can be connected inside the relatively spacious protective channel 301b, which can also be sealed and protected. After the explosion-proof three-phase asynchronous vibration motor body 1 is installed, the user can rotate the bearing rod 302b fixed at the bottom of the fixing rod 302a back to the position facing the explosion-proof three-phase asynchronous vibration motor body 1, so that the sealing protective cylinder 302c, the reinforcing rod 302d, and the positioning rod 302e supported by the bearing rod 302b and the metal connectors used for the installation of the explosion-proof three-phase asynchronous vibration motor body 1 are in the vertical direction. Then the user can rotate the positioning rod 302e. Under the action of the thread, the positioning rod 302e can drive the sealing protective cylinder 302c to move upward, so that it can seal and protect the metal connectors.

[0046] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the scope of the present utility model should be included within the protection scope of the present utility model.
