Description

Technical Field

[0001] The invention relates to the technical field of flange motors, and in particular to a heat dissipation motor with a flange. Background Art

[0002] Flange motor is a kind of electric motor. There are two main types of flanges on flange motors. One is the "large flange", which generally refers to the end cover of the motor, which is used to support the rotor of the motor, place the bearing, and sometimes also seal the motor. The other is the "small flange", which generally refers to the bearing cover, which is used to fix and protect the bearing.

[0003] Flange motors are widely used in various mechanical equipment and industrial automation fields, such as machine tools, water pumps, rear fans, etc. At the same time, they are also used in production lines to provide power support for industrial automation.

However, when flange motors are used in some special environments, such as boiler rooms, paint rooms, etc., the temperature of the external environment is relatively high.

[0036] The following will refer to Figures 1 to 12 The embodiments of the present invention are described in detail. It should be understood by those skilled in the art that these embodiments are only used to explain the technical principles of the present invention and are not intended to limit the protection scope of the present invention.

[0037] First embodiment:

[0038] A heat dissipation motor with a flange includes a motor body 1, a cover 2 for installing a rear fan 5 is installed on the side of the motor body 1 away from the flange, and the rear fan 5 is installed on the output end 14 of the motor tail. When the device is started, the output end 14 of the motor tail drives the rear fan 5 to rotate. This is the prior art and will not be described in detail; a heat dissipation blade 4 is installed on the outer surface of the motor body 1, an annular air duct 3 is opened on the motor body 1, one end of the annular air duct 3 is connected to the inside of the cover 2, and a guide shell 6 is provided on the motor body 1, and the outlet of the guide shell 6 faces the heat dissipation The blades 4 are provided, and more than two air outlets 7 are provided on the motor body 1. The air outlets 7 are provided near the other end of the annular air duct 3. The annular air duct 3 is connected with the inside of the guide shell 6 through the guide shell 6. When the rear fan 5 rotates, air is transported into the annular air duct 3 (the first heat exchange). The airflow in the annular air duct 3 flows into the guide shell 6 through the air outlets 7, and then the airflow is blown toward the heat dissipation blades 4 through the outlet of the guide shell 6 (the second heat exchange), realizing two-way heat exchange, so that the heat dissipation effect of the device is higher. This embodiment can be applied to both vertical motors and horizontal motors. Figure 1-Figure 2 It is a vertical motor structure. Figure 3-Figure 4 It is a horizontal motor structure.

[0039] A water tank 8 is provided on the side of the motor body 1, and a water inlet pipe seat 44 is provided on the water tank 8. The input end of the water inlet pipe seat 44 is connected to an external water supply device (for example, a water storage tank with a certain pressure), and the external water supply device transports water to the water tank 8 through the water inlet pipe seat 44; the water tank 8 is connected to the bottom of the annular air duct 3. By setting the water tank 8, when the airflow passes through the annular air duct 3, the volatilization of the water in the water tank 8 can be accelerated, and the airflow mixed with water vapor flows in the annular air duct 3 and blows toward the heat dissipation blades 4, further improving the heat dissipation effect of the device.

[0040] Second embodiment:

[0041] Based on the first embodiment, a partition 9 is provided in the water tank 8, and the partition 9 divides the space inside the water tank 8 into an upper chamber 10 and a lower chamber 11. The upper chamber 10 is connected to the bottom of the annular air duct 3, and the output end of the water inlet pipe seat 44 is connected to the interior of the lower chamber 11; a water inlet 12 is opened on the partition 9, and a closing plate mechanism matching the water inlet 12 is provided on the partition 9, and a temperature control mechanism is provided on the motor body 1, and the temperature control mechanism is connected to the closing plate mechanism by driving; a water level detection mechanism is provided in the upper chamber 10, and the water level detection mechanism is connected to the closing plate mechanism by driving; in the initial state, the closing plate mechanism is in a closed water inlet 12 state to prevent the water in the lower chamber 11 from volatilizing. When the temperature control mechanism detects that the temperature inside the motor body 1 is too high, the temperature control mechanism drives the closing plate mechanism so that the closing plate mechanism no longer closes the water inlet 12, and the water in the lower chamber 11 flows into the upper chamber 10.

[0042] The temperature control mechanism includes a temperature measuring tube 17 installed on the motor body 1, the top of the temperature measuring tube 17 is inserted into the interior of the motor body 1, a piston 18 is slidably fitted in the temperature measuring tube 17, a temperature-sensitive expansion body 45 is provided between the top of the piston 18 and the inner top wall of the temperature measuring tube 17, the temperature-sensitive expansion body 45 is made of temperature-sensitive memory metal, a first spring 19 is installed between the bottom of the piston 18 and the inner bottom wall of the temperature measuring tube 17, a rack 20 is fixedly connected to the bottom of the piston 18, and the bottom end of the rack 20 passes through the temperature measuring tube 17; when the internal temperature of the motor body 1 rises, the temperature-sensitive expansion body 45 expands due to the heat, and then pushes the piston 18 to descend and pushes the rack 20 to descend.

[0043] The closing plate mechanism includes a rotating shaft 21 rotatably connected to the partition 9, a closing plate 22 matching the water inlet 12 is fixedly connected to the rotating shaft 21, a rotating drum 23 is rotatably connected to the water tank 8, one end of the rotating shaft 21 is inserted into the interior of the rotating drum 23, and the rotating shaft 21 and the rotating drum 23 are coaxially arranged, a volute spring 24 is installed between the outer surface of the rotating shaft 21 and the inner wall of the rotating drum 23, a first gear 25 is coaxially fixedly connected to the rotating drum 23, and the rack 20 is meshed with the first gear 25; when the rack 20 descends, the first gear 25 is driven to rotate with the rotating drum 23, and since the rotating drum 23 is connected to the rotating shaft 21 through the volute spring 24, the rotating shaft 21 rotates with the closing plate 22, and the water inlet 12 opens.

[0044] The water level detection mechanism includes a slide groove 26 opened on the side wall of the water tank 8, the slide groove 26 is located between the cover shell 2 and the upper chamber 10, a slider is slidably matched in the slide groove 26, a floating plate 27 is provided in the upper chamber 10, the slider is fixedly connected to the floating plate 27, a pull rope 28 is provided between the closing plate 22 and the floating plate 27, an L-shaped rod 29 is provided on the side of the slider away from the floating plate 27, and a slope 30 is provided on the top of the L-shaped rod 29, a sealing film 31 is installed between the inner wall of the slide groove 26 and the L-shaped rod 29, the sealing film 31 plays the role of sealing the slide groove 26 to prevent the water in the upper chamber 10 from flowing out through the slide groove 26; through the setting of the water level detection mechanism, when the water height in the upper chamber 10 reaches the set value, the water inlet 12 is controlled to be closed.

[0045] An annular water-absorbing layer is arranged in the annular air duct 3, and the annular water-absorbing layer includes an annular bracket 13, and a water-absorbing pad 15 is fixedly connected to the annular bracket 13. The water-absorbing pad 15 is covered with holes, and the water-absorbing pad 15 is made of a hydrophilic material, such as silica gel, sponge, etc., and a plurality of vents 16 are arranged on the water-absorbing pad 15 in a direction parallel to the central axis. Through the arrangement of the annular air duct 3, the water-absorbing pad 15 and the vents 16, the working noise of the internal components of the motor body 1 can be prevented from being transmitted to the outside, thereby improving the noise reduction performance of the device, and the water-absorbing pad 15 can absorb the water in the upper chamber 10, and when the air flow flows through the vents 16, the volatilization of the water on the water-absorbing pad 15 can be accelerated, and the air flow mixed with water vapor flows in the annular air duct 3 and blows toward the heat dissipation blades 4, so that the heat dissipation effect of the device is higher.

[0046] A connecting wheel mechanism is rotatably arranged in the cover shell 2, and the annular water absorbing layer is coaxially connected to the connecting wheel mechanism; the connecting wheel mechanism includes a supporting wheel 32 rotatably arranged on the motor body 1, the annular bracket 13 is coaxially fixedly connected to the supporting wheel 32, and a second gear 33 is coaxially fixedly connected to the supporting wheel 32; a mounting frame 46 is fixedly connected to either the motor body 1 or the cover shell 2, and a first central axis 35 is rotatably connected to the mounting frame 46, and a third gear 34 is coaxially fixedly connected to one end of the first central axis 35 close to the second gear 33, and the second gear 33 is meshingly connected to the third gear 34, and the diameter of the second gear 33 is larger than the diameter of the second gear 33; a reduction mechanism is provided on the output end 14 of the motor tail, and a butt top is provided on the reduction mechanism, and a receiving part matching the butt top is movably connected to the connecting wheel mechanism, and a water level detection mechanism is drivingly connected to the receiving part; when the water level in the upper chamber 10 rises, the water level detection mechanism drives the receiving part of the connecting wheel mechanism to move and correspond to the butt top of the reduction mechanism, so that the reduction mechanism drives the connecting wheel The mechanism rotates; a baffle 36 is fixedly connected to the other end of the first central axis 35, and an annular push plate 37 is slidably matched on the first central axis 35, and the annular push plate 37 matches the inclined surface 30 on the top of the L-shaped rod 29, and a second spring 38 is installed between the baffle 36 and the annular push plate 37, and a receiving block 39 is fixedly connected to the side of the annular push plate 37 close to the reduction mechanism; the reduction mechanism includes a fourth gear 40 coaxially fixedly connected to the output end 14 of the tail of the motor, and a second central axis 41 is rotatably connected to the mounting frame 46, the first central axis 35 is coaxially arranged with the second central axis 41, and a push block 42 matching the receiving block 39 is provided at one end of the second central axis 41 close to the first central axis 35, and a fifth gear 43 is coaxially fixedly connected to the other end of the second central axis 41, the fourth gear 40 is meshed with the fifth gear 43, and the diameter of the fourth gear 40 is smaller than the diameter of the fifth gear 43; in the initial state, the slow rotation of the water-absorbing pad 15 can be achieved through the coordinated arrangement of the connecting wheel mechanism and the reduction mechanism.

[0047] The working principle of the device in this embodiment is as follows: in the initial state, the closing plate 22 is in the state of closing the water inlet 12. When the device in this embodiment is working, the rear fan 5 is driven to rotate based on the motor tail output end 14 in the first embodiment to deliver air to the input end of the annular air duct 3. The airflow is input to the other end of the annular air duct 3 through the vent 16, and then the airflow is blown to the heat dissipation blade 4 through the outlet of the guide shell 6, so as to realize the use of air heat exchange; under the influence of factors such as the working environment temperature of the device, when the temperature inside the motor body 1 continues to rise under the air heat exchange operation, the temperature-sensitive expansion body 45 is heated and expands and presses against the active The plug 18 descends. When the temperature inside the motor body 1 rises to the set value, the temperature-sensitive expansion body 45 pushes against the piston 18 and descends to push the rack 20 down (at the same time, the first spring 19 is compressed and stores force). The first gear 25 drives the rotating drum 23 to rotate forward. Since the rotating drum 23 is connected to the rotating shaft 21 through the volute spring 24, the rotating shaft 21 drives the closing plate 22 to rotate forward (at this time, the pull rope 28 is in a relaxed state and the closing plate 22 is set narrower, that is, the rotation resistance of the closing plate 22 is small, and the volute spring 24 will not store force), so that the water inlet 12 is opened, and the water in the lower chamber 11 flows into the upper chamber 10.

[0048] As water continues to flow into the upper chamber 10, the float plate 27 slowly rises. When the float plate 27 rises to a set height (the water level in the upper chamber 10 reaches the set height), the pull rope 28 pulls the closing plate 22 to rotate in the opposite direction (at the same time, the volute spring 24 accumulates force and is acted upon by the restraining force of the rack 20. At this time, the torque of the volute spring 24 acting on the rotating drum 23 is not sufficient to cause the first gear 25 to rotate in the opposite direction), so that the closing plate 22 blocks the water inlet 12, that is, the water in the lower chamber 11 can no longer flow into the upper chamber 10.

[0049] It should be noted that after the water-absorbing pad 15 absorbs the water in the upper chamber 10, when the air flow flows through the vent 16, the water on the water-absorbing pad 15 can be volatilized, so that the air flow mixed with water vapor can cool the motor body 1, and the heat dissipation effect of the device is further improved; it is worth noting that after the water-absorbing pad 15 absorbs the water in the upper chamber 10, when the water level in the upper chamber 10 decreases, the float plate 27 descends to relax the pull rope 28, the volute spring 24 releases the force and causes the closing plate 22 to rotate forward, and the water inlet 12 opens to allow water to enter the upper chamber 10 again, so that during the process of cooling the motor body 1 by the air flow mixed with water vapor, the water level in the upper chamber 10 is close to constant.

[0050] It should be noted that the heat dissipation structure of the present invention applied to vertical motors and horizontal motors is the same, but the vertical motor needs to additionally set a pulley or an arc guide groove in the motor body to adjust the direction of the pull rope. Since the structure of the pulley and the arc guide groove is the existing technology in this field, it will not be repeated here.

[0051] In addition, during the rising process of the floating plate 27, the L-shaped rod 29 is driven to rise, and the inclined surface 30 on the L-shaped rod 29 pushes against the annular push plate 37 to make the annular push plate 37 move closer to the second central axis 41 (at the same time, the second spring 38 is compressed and stored), and the receiving block 39 moves in the same direction and corresponds to the pushing block 42. At this time, when the tail output end 14 of the motor rotates, the fourth gear 40 drives the fifth gear 43 to rotate with the second central axis 41, and the pushing block 42 pushes the receiving block 39 to make the annular push plate 37 rotate with the first central axis 35, and the third gear 34 drives the second gear 33 to rotate. The support wheel 32 drives the annular bracket 13 to rotate with the water-absorbing pad 15 (the diameter of the second gear 33 is larger than the diameter of the second gear 33 and the diameter of the fourth gear 40 is smaller than the diameter of the fifth gear 43, so that the water-absorbing pad 15 rotates slowly, ensuring that the water-absorbing pad 15 has sufficient time to absorb water). During the heat dissipation operation of the device, the water-absorbing pad 15 rotates slowly, ensuring that the water content of each part of the water-absorbing pad 15 can meet the heat dissipation demand, preventing the water-absorbing pad 15 from being affected by airflow and having large humidity differences at various parts, resulting in large differences in heat dissipation at various parts of the motor body 1.

[0052] When the temperature inside the motor body 1 drops, the temperature-sensitive expansion body 45 contracts, the first spring 19 releases its force and pushes the piston 18 to rise, the rack 20 rises and drives the first gear 25 to rotate with the drum 23 in the opposite direction. If the water inlet 12 is in an open state at this time, the closing plate 22 rotates and blocks the water inlet 12.

[0053] As the amount of water in the upper chamber 10 decreases, the floating plate 27 decreases, and the L-shaped rod 29 decreases and no longer presses against the annular push plate 37. The second spring 38 releases its force to press the annular push plate 37 to reset, that is, the receiving block 39 is separated from the push block 42, and the water-absorbing pad 15 will no longer rotate.
