Description

Technical Field

[0001] This utility model relates to the field of explosion-proof motor technology, and in particular to a novel explosion-proof motor. Background Technology

[0002] With the continuous expansion of the industrial sector and the sustained growth in demand for energy, electric motors, as the core power source for various mechanical equipment, are increasingly widely used, covering many industries with flammable and explosive hazards, such as petrochemicals, coal mining, pharmaceuticals, and food processing. In these special environments, the safe and reliable operation of electric motors has become a key factor in ensuring the smooth operation of the entire production process and avoiding major safety accidents.

[0003] However, existing explosion-proof motors still have the following two problems in use:

[0004] First, the connection between the motor and the wire is often just a simple seal. When subjected to external forces such as pulling or vibration, the connection can easily loosen, generating electric sparks and becoming a potential hazard to ignite surrounding flammable and explosive materials.

[0005] Secondly, in order to meet explosion-proof requirements, many explosion-proof motors have well-sealed casings, but this hinders the dissipation of heat generated during motor operation. Poor heat dissipation will cause the internal temperature of the motor to be too high, which will not only affect the service life of the motor, but may also lead to problems such as reduced insulation performance and damage to parts. Utility Model Content

[0006] This utility model relates to a novel explosion-proof motor, which solves the problems that the wiring of the motor is prone to loosening when subjected to external forces such as pulling and vibration, and that the sealed shell of the explosion-proof motor hinders the dissipation of heat generated during motor operation.

[0007] This utility model provides a novel explosion-proof motor, specifically including: a motor body;

[0008] A fixing sleeve is installed at the front end of the outer end of the motor body, a base is welded to the lower end face of the fixing sleeve, two annular baffles are welded to the outer end face of the motor body, and a junction box is fixedly installed at the rear end face of the outer end of the motor body.

[0009] The protective cover is provided in two symmetrical sets, with the two protective covers located outside the motor body, and heat dissipation holes are evenly distributed on the surface of the protective cover;

[0010] The sleeve is provided in two parts. The two sleeves are fixedly installed on the outer end face of the junction box. The wires outside the junction box are clamped inside the sleeves. Two sets of through holes are symmetrically opened on the surface of the sleeves.

[0011] The pressure plate is provided in two symmetrical sets. The pressure plate is located inside the sleeve. The outer end face of the pressure plate is a horizontal structure. Two tension rods are fixedly installed on the outer end face of the pressure plate.

[0012] Furthermore, a heat dissipation copper plate is uniformly installed on the outer end face of the motor body, and a through hole is opened on the surface of the heat dissipation copper plate and the two ends of the heat dissipation copper plate are attached to the baffle.

[0013] Furthermore, the surface of the baffle is symmetrically provided with two slots, and two locking blocks are respectively installed at the front and rear ends of the protective cover. When the two protective covers are fitted onto the outside of the motor body, the locking blocks at both ends of the protective cover are engaged in the slots on the surface of the baffle.

[0014] Furthermore, two connecting plates are symmetrically installed on the outer end face of the protective cover. The surface of the connecting plates is evenly provided with mounting holes, and bolts pass through the mounting holes to connect the two protective covers together.

[0015] Furthermore, the tension rod on the outer end face of the pressure plate is slidably engaged in the through hole on the surface of the sleeve, and an inclined limiting pin is installed on the lower end face of the pressure plate. A compression spring is sleeved on the outside of the tension rod, and the compression spring is located inside the sleeve.

[0016] Furthermore, a groove is provided in the middle of the lower end face of the base, and two sets of connecting holes are symmetrically provided on the surface of the base.

[0017] This utility model provides a novel explosion-proof motor, which has the following beneficial effects:

[0018] 1. Two tension rods are fixedly installed on the outer end face of the pressure plate. A compression spring is sleeved on the outside of the tension rod. Under the action of the spring force, the limiting clip at the lower end of the pressure plate can be tightly attached to the wire. In this way, when the wire is pulled by the outside, the limiting clip can resist the external pulling force, which can protect the wire and the junction box interface and prevent the joint from becoming loose. The tension rod is slidably locked in the through hole on the surface of the sleeve, so that the pressure plate can move up and down.

[0019] 2. The outer surface of the motor body is uniformly covered with heat dissipation copper plates, which can quickly absorb heat. The through holes on the surface of the heat dissipation copper plates increase the heat dissipation area and allow air to form convection on its surface, accelerating heat dissipation. The heat dissipation holes on the surface of the protective cover are evenly distributed to form air circulation channels, further improving the heat dissipation effect.

[0020] 3. Two protective covers are located outside the motor body. Each of the front and rear ends of the protective cover is equipped with a locking block. Workers can engage the locking blocks at both ends of the protective cover with the slots on the surface of the baffle to limit the movement of the protective cover. Each end of the protective cover is equipped with a connecting plate. Bolts can be passed through the mounting holes on the surface of the connecting plate to connect the two protective covers. The protective covers protect the motor body and can effectively prevent the explosion fragments from spreading to the external environment after the motor body explodes.

[0021] 4. The groove on the lower end face of the base can be embedded with a shock-absorbing pad to reduce the transmission of vibration during motor operation. The surface of the base has connection holes, and the motor can be firmly installed on the equipment foundation by bolts, which facilitates the disassembly and assembly of the base by workers.

[0037] The protective cover 3 is provided in two sets symmetrically. The two protective covers 3 are located outside the motor body 1. The surface of the protective cover 3 is evenly provided with heat dissipation holes 301.

[0038] Sleeve 4, two sleeves 4 are provided, the two sleeves 4 are fixedly installed on the outer end face of junction box 104, the wires outside junction box 104 are clipped into the inside of sleeve 4, and two sets of through holes 401 are symmetrically opened on the surface of sleeve 4.

[0040] The outer end face of the motor body 1 is uniformly equipped with a heat dissipation copper plate 103. The inner end of the surface of the heat dissipation copper plate 103 is provided with a through hole 1031. Both ends of the heat dissipation copper plate 103 are attached to the baffle 102. The heat dissipation copper plate 103 is uniformly installed on the outer surface of the motor body 1, which can quickly absorb heat. The through hole 1031 on the surface of the heat dissipation copper plate 103 increases the heat dissipation area and allows air to form convection on its surface, accelerating heat dissipation.

[0041] The baffle 102 has two symmetrical slots 1021 on its surface. The protective cover 3 has two locking blocks 303 installed at its front and rear ends respectively. When the two protective covers 3 are fitted onto the outside of the motor body 1, the locking blocks 303 at both ends of the protective cover 3 are engaged in the slots 1021 on the surface of the baffle 102. The locking blocks 303 engaged in the slots 1021 can limit the position of the protective cover 3.

[0042] Among them, two connecting plates 302 are symmetrically installed on the outer end face of the protective cover 3. The surface of the connecting plate 302 is evenly provided with mounting holes 3021. Bolts pass through the mounting holes 3021 to connect the two protective covers 3 together.

In this way, when the wire is pulled by the outside, the limiting pin 501 can resist the external pulling force, which can protect the interface between the wire and the junction box 104 and prevent the joint from becoming loose. The tension rods 502 are slidably clipped into the through holes 401 on the surface of the sleeve 4, so that the pressure plate 5 can move up and down. A heat dissipation copper plate 103 is evenly installed on the outer surface of the motor body 1, which can quickly absorb heat. The through holes 1031 on the surface of the heat dissipation copper plate 103 increase the heat dissipation area and allow Air convection is formed on its surface, accelerating heat dissipation. The heat dissipation holes 301 on the surface of the protective cover 3 are evenly distributed, forming an air circulation channel, which further improves the heat dissipation effect. The two protective covers 3 are located outside the motor body 1. A locking block 303 is installed at the front and rear ends of the protective cover 3. Workers can lock the locking blocks 303 at both ends of the protective cover 3 into the locking grooves 1021 on the surface of the baffle 102 to limit the position of the protective cover 3. A connecting plate 302 is installed at both ends of the protective cover 3. Bolts can be passed through the mounting holes 3021 on the surface of the connecting plate 302 to connect the two protective covers 3.
