Description

Technical Field

[0001] The invention relates to the technical field of motors, and in particular to an explosion-proof switched reluctance motor. Background Art

[0002] The explosion-proof switched reluctance motor is a motor that can operate safely in flammable, explosive and other hazardous environments. It inherits the advantages of the switched reluctance motor, such as simple structure, durability, high-speed performance and low cost. Through special design and material selection, it ensures that no sparks or high temperatures will be caused in potentially explosive environments, thereby avoiding explosions or fires.

[0003] At present, in the process of using the existing switched reluctance motor, when the heat dissipation treatment is performed on the rotor and the stator, the heat generated by the rotor and the stator cannot be taken away quickly and timely, and the temperature of each part will be inconsistent during the heat dissipation, resulting in the appearance of a local high stable point, so that the rotor and the stator have inconsistent expansion and contraction degrees, resulting in vibration during operation, thereby affecting the stability and reliability of the switched reluctance motor;

[0004] Moreover, during the heat dissipation process, the flow rate of the coolant cannot be adjusted according to the speed of the switched reluctance motor, resulting in more heat generated when the speed is too fast and the heat generated cannot be taken away in time.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0020] 2. When the shaft rotates, the squeezing roller squeezes the hose. Since the squeezing roller is fixed on the shaft through the fixed shaft and the bracket, the squeezing roller can maintain the same speed as the shaft. The flow rate of the coolant can be automatically adjusted according to the different speeds, so that the coolant always maintains an efficient cooling effect, which can also avoid energy consumption and improve the degree of automation.

[0021] 3. Since the inside of the cooling box and the cooling cavity are connected, the coolant can be stored in the cooling cavity, and the cooling cavity can be heat-dissipated at the same time. The coolant in the cooling cavity forms a protective effect, thereby reducing the transmission of noise and achieving a noise reduction effect;

[0022] 4. During the liquid cooling process, the rotor and the first interconnecting block can be air-cooled again through the fan blades. Therefore, under the dual cooling effects of liquid cooling and air cooling, the rotor and the first interconnecting block can have an excellent cooling effect. The fan blades can carry the heat of the coolant in the cooling chamber, so that the coolant always maintains a low temperature, thereby ensuring the overall cooling effect. Since the power source is only the shaft, the production cost can be saved;

[0023] 5. The structure in the disassembly and assembly mechanism can simultaneously move the limit column outward, thereby releasing the limit on the positioning column, thus saving a lot of time during disassembly and installation, thereby improving the disassembly and installation efficiency.

The coolant can flow into the central cavity 33 and the dispersed cavity 34 respectively through the square holes 35.

[0046] like Figure 3 , Figure 5 - Figure 6 As shown, a partition plate 25 is fixedly connected to the inner wall of the cooling box 3, and the partition plate 25 divides the cooling box 3 into two water storage chambers. A cooling chamber 16 is opened on the explosion-proof housing 1, and the cooling chamber 16 is connected with the two water storage chambers through two through holes. The input pipe 2 and the output pipe 4 extend into the two water storage chambers respectively, and the two water storage chambers are connected with the input pipe 2 and the output pipe 4 respectively, so that the coolant in the cooling chamber 16 can be in a flowing state, so that the coolant can be better cooled, thereby ensuring the cooling effect on the rotor 14 and the stator 19.

[0047] like Figure 3 , Figure 5 , Figure 7 - Figure 8 As shown, the cooling mechanism also includes a fan blade 12 fixedly connected between the first connecting block 15 and the bracket 30 corresponding to the outer wall of the rotating shaft 9. The fan blade 12 is used for air cooling and heat dissipation of the rotor 14 and the stator 19, and can cool the coolant in the cooling chamber 16. The rotation speed of the fan blade 12 changes with the change of the rotation speed of the rotating shaft 9.

[0048] like Figure 1 - Figure 2 , Fig.11 , Fig.13 As shown, the filtering mechanism includes an annular filter 11 fixedly mounted on the explosion-proof housing 1 and an annular filter 10 fixedly mounted on the end cover 6. A plurality of ventilation and heat dissipation holes are provided at positions corresponding to the annular filter 11 on the explosion-proof housing 1, and a plurality of ventilation and heat dissipation holes are provided at positions corresponding to the annular filter 10 on the end cover 6. The ventilation and heat dissipation holes can be used to keep the air inside the switched reluctance motor in a flowing state when the fan blades 12 are running, and the annular filter 10 and the annular filter 11 can filter the incoming air to prevent external dust from entering the switched reluctance motor and prevent internal components from being short-circuited due to contact with a large amount of dust, leading to spontaneous combustion.

[0049] like Figure 4 , Fig.11 - Fig.14As shown, the disassembly and assembly mechanism includes a positioning column 24 fixedly connected to the front end of the explosion-proof housing 1, and the number of positioning columns 24 is set in multiple. A limiting groove 36 is provided at one end of the outer side of the multiple positioning columns 24. The disassembly and assembly mechanism also includes a positioning groove 20 provided at one end of the end cover 6 close to the explosion-proof housing 1 and adapted to the shape of the positioning column 24. The number of positioning grooves 20 and positioning columns 24 is the same. The outer wall of the end cover 6 is slidably penetrated by multiple limiting columns 5 and extends into the positioning groove 20. One end of the outer side of the multiple limiting columns 5 is fixedly connected with a fixing plate 28, and one end of the multiple fixing plates 28 close to the end cover 6 corresponds to the outer side of the limiting column 5. A plurality of tension springs 37 are fixedly connected to the end cover 6. The cooperation of the positioning column 24 and the positioning groove 20 can make the end cover 6 in the correct position during installation, and the limiting column 5 is inserted into the limiting groove 36 to complete the rapid installation and disassembly of the end cover 6.

A plurality of slide grooves 26 are provided on the outer walls of the protrusions 7 and the disassembly ring 8, and a plurality of slide grooves 26 are slidably connected to the inner walls of the plurality of slide grooves 26. The plurality of slide rods 27 and the fixed plate 28 are fixedly connected. When the disassembly ring 8 is rotated, the slide rods 27 will gradually contact the protrusions 7, so that all the slide rods 27 can be moved outward, thereby moving the fixed plate 28 outward, so that the limit on the positioning column 24 can be released at the same time, saving time.

[0051] Working principle: The operation of the rotor 14 and the stator 19 is ensured by heat dissipation and cooling of the rotor 14 and the stator 19. First, the rotation of the rotating shaft 9 can drive the bracket 30 to rotate, and the squeezing roller 29 rotates on the fixed shaft 21. Therefore, the squeezing roller 29 can rotate itself while revolving around the axis of the rotating shaft 9. Therefore, the hose 38 can be squeezed, so that the coolant in the cooling box 3 can flow into the first communication block 15 through the input pipe 2 and the U-shaped pipe 17, and then the coolant can flow into each second flow channel 32 and the first flow channel 31 through the first connecting pipe 13 and the dispersion cavity 34, so that the rotor 14 and the stator 19 can be cooled to prevent the rotor 14 and the stator 19 from overheating. After the cooling treatment, the coolant flows into the second communication block 22 through the second connecting pipe 23 and the concentrated cavity 33, and then flows back into the cooling box 3 through the output pipe 4 to complete the cooling operation;

[0052] During the cooling operation, the fan blades 12 can be used for air cooling, thereby improving the cooling effect, and the fan blades 12 can also cool the coolant in the cooling chamber 16 to ensure the cooling effect of the coolant, and the annular filter 11 and the annular filter 10 can prevent external dust from entering the switched reluctance motor during air cooling;

[0053] When installing the end cover 6, the disassembly ring 8 can be rotated first. When the slide bar 27 contacts the protruding block 7, the slide bar 27 will move outward at the same time, and the fixing plate 28 will move outward, so that the limiting column 5 leaves the range of the positioning groove 20. At this time, the positioning column 24 is inserted into the positioning groove 20 and the disassembly ring 8 is released. At this time, the limiting column 5 is inserted into the limiting groove 36 under the resetting action of the tension spring 37 to complete the limiting of the positioning column 24, thereby completing the installation operation of the end cover 6.

[0054] When disassembly is required, the end cover 6 can be disassembled quickly by operating the above structure, which is convenient and quick.

[0055] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions only describe the principles of the present invention. The present invention may be subject to various changes and improvements without departing from the spirit and scope of the present invention.
