[0002] The explosion-proof motor frame is an important part of the explosion-proof motor, which is designed for flammable and explosive environments. It is usually made of high-strength materials such as cast steel or gray cast iron to ensure strength and durability. The frame structure must meet explosion-proof standards and its sealing must be verified by a water pressure test. In addition, the frame size and installation method must meet specific specifications to ensure safe and stable operation of the motor.

[0003] The existing explosion-proof motor base rear cover area has some deficiencies in heat dissipation and dust prevention. In terms of heat dissipation, the heat dissipation end cover structure of ordinary explosion-proof motors is single, and the heat dissipation is not strong enough, which will increase the temperature of the rear part of the motor and affect safety. In addition, when the cooling fan is working, the air flow is poor due to the rotation of the fan, and it is easy to diverge and flow outward on the outside of the base and the heat dissipation strips, resulting in poor cooling effect on the part far away from the cooling fan. In terms of dust prevention, although the open motor has good heat dissipation, it is easy to get dust, water droplets, iron filings and other debris, and can only be used in a clean and dry environment. The explosion-proof motor base may not have sufficient sealing in the dust-proof design, which makes it easy for dust to enter the inside of the motor, affecting the normal operation and maintenance of the motor.

[0032] Example 1 Reference Figure 1 to Figure 4 , which is the first embodiment of the present invention, provides an explosion-proof motor base that is easy to clean, which includes a base body 100, a connecting foot 101 is fixed to the bottom of the base body 100, and a rear cover 102 is also built into the rear of the base body 100.

[0033] Among them, the base body 100 is made of cast steel as a whole, and the inner and outer walls are anti-corrosion treated. Necessary components such as the motor shaft and coil are installed in the base body 100. The end of the base body 100 opposite to the motor shaft is the tail of the motor. The rear cover 102 is covered and fixed on the tail of the base body 100, which can provide functions such as heat dissipation and dust prevention.

[0034] The dust shield assembly 200 includes a tail cover 201 and an internal baffle 202 . The internal baffle 202 and the tail cover 201 are fixed to the inner cavity of the rear cover 102 and the end of the rear cover 102 respectively. A plurality of guide baffles 203 are connected between the tail cover 201 and the internal baffle 202 .

[0035] The internal baffle 202 completely covers the necessary components for the operation of the motor, such as the shaft, within the inner base body 100 . The internal baffle 202 not only protects the motor components, but also provides a heat dissipation channel to prevent the temperature inside the base body 100 from being too high.

[0036] The rear cover 102 includes a fixed section 102a and an external section 102b, and the outer wall of the external section 102b is fixedly connected to the inner wall of the fixed section 102a.

[0037] Reference Figure 3 The outer diameter of the circumscribing section 102b is the same as the inner diameter of the fixing section 102a, so that a step is formed between the fixing section 102a and the circumscribing section 102b.

[0038] A plurality of bolt holes 102a - 1 are formed on the circumferential outer wall of the fixing section 102a , and a plurality of engaging grooves 102b - 1 are formed on the circumferential outer wall of the external connection section 102b .

[0039] The engaging groove 102b-1 includes a rotating groove 102b-1a and a connecting groove 102b-1b. The rotating groove 102b-1a is communicated with the external space through the connecting groove 102b-1b.

[0040] The engaging groove 102b-1 is an "L"-shaped groove, the rotating groove 102b-1a is a vertical section of the "L"-shaped groove, and the connecting groove 102b-1b is a horizontal section of the "L"-shaped groove.

[0041] A sleeve ring 103 is fixed to one end of the base body 100 away from the motor shaft, and the fixed section 102a is fixedly sleeved outside the sleeve ring 103. The internal baffle 202 can be sealed and fixed to the end of the sleeve ring 103; a plurality of ventilation holes 202a are opened on the internal baffle 202.

[0042] The ventilation holes 202 a connect the internal space of the base body 100 with the external environment to achieve heat dissipation in the internal space of the base body 100 .

[0043] During use, the staff will sleeve the fixing section 102a on the sleeve ring 103, insert the bolt into the bolt hole 102a-1, and then further thread it with the sleeve ring 103, and finally fix the rear cover 102 as a whole on the sleeve ring 103.

[0044] Example 2 Reference Figure 1 to Figure 6 , which is the second embodiment of the present invention. This embodiment is different from the first embodiment in that the tail cover 201 includes a protective cover 201a and a cleaning piece 201b fixedly engaged with it, and the protective cover 201a is fixedly connected to the circumferential outer wall with a plurality of groups of snap-fit ​​blocks 201a-1, and the snap-fit ​​blocks 201a-1 can slide in the rotating groove 102b-1a and the connecting groove 102b-1b.

[0045] During use, if the tail cover 201 is to be installed on the rear cover 102, the staff can align the clamping block 201a-1 with the connecting groove 102b-1b, and then press the protective cover 201a to move the clamping block 201a-1 to the starting end of the rotating groove 102b-1a.

[0046] Furthermore, the staff slightly rotates the protective cover 201a, and the engaging edge block 201a-1 rotates along the rotating groove 102b-1a. If there is no external force to reset the protective cover 201a, the protective cover 201a will be fixed on the rear cover 102.

[0047] A dust blocking net 201a-2 is sealed and fixed to one end of the protective cover 201a, and a sealing cover 201a-3 is also fixed to the outer wall of the protective cover 201a, and the inner wall of the sealing cover 201a-3 is fixed to the clamping block 201a-1.

[0048] Among them, the dust-blocking net 201a-2 is the first layer of protection of the device, realizing the first step of dust protection, and the sealing cover 201a-3 can ensure the sealing of the protective cover 201a from the side.

[0049] An abutment ring 201a-4 is fixedly connected in the protective cover 201a, and a plurality of groups of first hinge blocks 201a-4a are fixedly connected to the inner wall of the abutment ring 201a-4 at equal intervals.

[0050] A plurality of docking grooves 201a-5 are evenly spaced apart at one end of the protective cover 201a away from the dust blocking net 201a-2.

[0051] The cleaning member 201b includes a snap ring 201b-1 and a push ring 201b-2 coaxially arranged therewith, and the snap ring 201b-1 can be coaxially placed in the external section 102b.

[0052] A plurality of groups of insert blocks 201b-1a are fixed at equal intervals on the circumferential outer wall of the clamping ring 201b-1, and the insert blocks 201b-1a can be inserted into the docking groove 201a-5.

[0053] During use, before installing the protective cover 201a onto the rear cover 102, the cleaning piece 201b needs to be coaxially placed inside the protective cover 201a, and the insert block 201b-1a is located in the docking groove 201a-5.

[0054] A plug sleeve 201b-1b is also provided in the middle of the clamping ring 201b-1, and the plug sleeve 201b-1b is fixed to the clamping ring 201b-1 through a plurality of groups of scrapers 201b-1c.

[0055] One end of the snap ring 201b-1 is fixedly connected to the first spring T1, and the other end of the first spring T1 is fixed to the end of the push ring 201b-2.

[0056] One end of the push ring 201b-2 close to the snap ring 201b-1 is fixedly connected with a covering ring 201b-2a, and the first spring T1 is slidably sleeved outside the covering ring 201b-2a.

[0057] Compared with Example 1, further, referring to Figure 6 During the installation of the tail cover 201, the retaining ring 201b-1 is gradually pushed from the outside into the rear cover 102 and finally abuts against the internal baffle 202. During this process, the first spring T1 changes from its original relaxed and straightened state to a compressed state, and the covering ring 201b-2a completely covers the first spring T1.

[0058] Furthermore, when the tail cover 201 is rotated and installed on the rear cover 102, the first spring T1 pushes the abutment ring 201a-4 through the pushing ring 201b-2, and further pushes the clamping block 201a-1, so that it is close to the inner wall of the rotating groove 102b-1a. At this time, the tail cover 201 as a whole is squeezed by the first spring T1 and will not easily rotate in the opposite direction, causing the tail cover 201 to separate from the rear cover 102.

[0059] Furthermore, if the motor needs to be cleaned and maintained and the protective cover 201a needs to be removed from the rear cover 102, the staff will rotate the tail cover 201 in the opposite direction. During the rotation, the scraper 201b-1c will clean the dust covering the internal baffle 202, reducing the difficulty of dust cleaning.

[0060] The remaining structures are the same as those of Example 1.

[0061] Example 3 Reference Figures 1 to 10, which is the third embodiment of the present invention. This embodiment is different from the second embodiment in that the guide baffle 203 includes a first plate 203a and a second plate 203b slidably arranged at the bottom thereof, and a plurality of groups of guide plates 203a-1 are equidistantly fixedly connected to one side of the first plate 203a, and air flow channels 203a-1a are formed between the guide plates 203a-1.

[0062] The first plate 203a and the second plate 203b both adopt a fan-shaped plate structure. In this embodiment, four groups are preferably provided respectively, and each group of first plates 203a corresponds to a group of second plates 203b.

[0063] Furthermore, the guide plate 203a-1 faces one side of the internal baffle plate 202. When the hot air inside the base body 100 flows out from the plurality of ventilation holes 202a opened on the internal baffle plate 202, it will flow around along the air flow channel 203a-1a, contact the inner wall of the protective cover 201a, perform heat exchange and cooling, and then further flow out from the dust shield 201a-2.

[0064] A slideway 203a-2 is provided in the middle of the other side of the first plate 203a, and a first rotating block 203a-3 is fixedly connected to the middle of the top end of the first plate 203a. The first rotating block 203a-3 is hinged to the first hinge block 201a-4a.

[0065] A groove 203b-1 is formed on one side of the second plate 203b, and a plug rod 203b-2 is fixedly connected to the top of the second plate 203b. The plug rod 203b-2 is slidably engaged in the slideway 203a-2. A second rotating block 203b-3 is also fixed to the bottom of the second plate 203b.

[0066] During use, the second plate 203b and the first plate 203a can slide relative to each other. When the guide baffle 203 is in a tilted state, the second plate 203b and the first plate 203a are in a relatively separated state, and the two are fixed by the plug-in connection of the plug rod 203b-2 and the slide 203a-2.

[0067] When the guide baffle 203 is in a vertical state, the second plate 203b and the first plate 203a are in a relatively fitted state, and the lower end of the first plate 203a can be fitted and placed in the groove 203b-1.

[0068] A pull rod 201c is axially slidably inserted in the middle of the dust blocking net 201a-2, and the outer walls at both ends of the pull rod 201c are respectively fixedly sleeved with a control sleeve 201c-1 and a rubber sleeve 201c-2, wherein the control sleeve 201c-1 and the rubber sleeve 201c-2 can be detachably fixed on the pull rod 201c.

[0069] A plurality of groups of second hinge blocks 201c-1a are fixedly connected to the circumferential outer wall of the control sleeve 201c-1, and the second rotating block 203b-3 is hinged to the second hinge block 201c-1a.

[0070] One end of the pull rod 201c which is sleeved with the control sleeve 201c-1 can be inserted into the inserting sleeve 201b-1b. The outside of the pull rod 201c is also sleeved with a second spring T2, and the two ends of the second spring T2 are respectively in contact with the control sleeve 201c-1 and the dust blocking net 201a-2.

[0071] Compared with Example 2, further, referring to Fig.10 During use, under the elastic force of the second spring T2, the pull rod 201c will drive the guide baffle 203 to tilt. At this time, the pull rod 201c can be inserted into the socket 201b-1b and cooperate with the dust blocking net 201a-2 to ensure the balance of the pull rod 201c.

[0072] Furthermore, after the motor has been running for a period of time, in order to improve the dust prevention and heat dissipation efficiency of the motor but without the need to disassemble and maintain it, the staff only needs to pull the rubber sleeve 201c-2 from the outside. At this time, the pull rod 201c is pulled, and the second plate 203b and the first plate 203a slide relative to each other, shrinking the space toward the dust blocking net 201a-2 to gather the blocked dust. The relative sliding between the second plate 203b and the first plate 203a will also cause vibration, shaking off the dust on the second plate 203b and the first plate 203a. At this time, the second plate 203b and the first plate 203a can also be used as cooling fins to exchange heat with the external space and cool down the internal environment of the base body 100.

[0073] The staff loosens the rubber sleeve 201c-2, the pull rod 201c is reset, and the second plate 203b and the first plate 203a resume the inclined state. At this time, the guide plate 203a-1 resumes the function of guiding the flow of heat.

[0074] The remaining structure is the same as that of Example 2.

[0075] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
