Description

Technical Field

[0001] The invention relates to the technical field of three-phase asynchronous motor monitoring, in particular to a three-phase asynchronous motor and a full-phase reactive power compensation device. Background Art

[0002] The following difficulties exist in the monitoring and use of the existing three-phase asynchronous motor drive unit: the long-term use of the three-phase asynchronous motor drive unit is likely to cause radial forces of different strengths to appear in the output shaft rotation, and these radial forces of different strengths will exceed the radial forces that the three-phase asynchronous motor output shaft can withstand, and finally cause the three-phase asynchronous motor output shaft to fail. It is difficult to monitor the internal working failure of the three-phase asynchronous motor output shaft, and the output shaft diameters of the three-phase asynchronous motors on the market are different, which further tightens the requirements for the monitoring device and increases its cost; secondly, during the operation of the three-phase asynchronous motor drive unit, the temperature generated inside it becomes higher and higher, which in turn affects the service life of the three-phase asynchronous motor. The traditional monitoring of the three-phase asynchronous motor only monitors a certain area of ​​the shell, and cannot accurately monitor the temperature of each area on the shell of the three-phase asynchronous motor, reducing the temperature monitoring effect of the three-phase asynchronous motor.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0038] See also Figures 1 to 15 The present invention provides a full-phase reactive power compensation device, including a base 1, a support base 2 is installed on the left end of the base 1, a base 3 for accommodating a motor is arranged on the top of the support base 2, a fine-tuning lifting component 4 for fine-tuning and moving the base 3 is arranged on the inner side of the support base 2, a temperature monitoring component 5 for monitoring the circumferential temperature of the motor is arranged on the inner side of the base 3, a transmission rod 8 is connected to the right end of the base 3 through the motor output shaft transmission, a ball monitoring component 6 for squeezing and rolling the outer wall of the transmission rod 8 is arranged on the right end of the base 1, a center monitoring component 7 for centering the motor output shaft is arranged on the left end of the ball monitoring component 6, and a clamping component 9 for clamping the outer wall of the transmission rod 8 is arranged on the inner side of the ball monitoring component 6.

[0039] As an embodiment of the present invention, Figure 1-Figure 3 As shown, the fine-tuning lifting assembly 4 includes a double-headed screw 41, two transversely arranged transverse grooves 21 are provided on the inner side of the support seat 2, and the double-headed screw 41 is rotatably connected on the inner side of the transverse groove 21, and the left and right ends of the double-headed screw 41 are threadedly connected with a moving block 42 that is slidably connected on the inner side of the transverse groove 21, and an inclined block 43 is installed on the top of the moving block 42, and a conical block adapted to the inclined block 43 is installed on the bottom end surface of the machine base 3. The left end of the double-headed screw 41 extends out of the support seat 2 and a linkage wheel 44 is installed on the outer side of the linkage wheel 44, and a linkage belt 45 is transmission-connected to the outer side of the linkage wheel 44, and a driving wheel 46 is installed on the left end of the linkage wheel 44 located on the rear side, and a longitudinally arranged sliding groove 411 is provided in the middle part of the support seat 2. L-shaped seats 412 sliding inside the sliding groove 411 are installed at the front and rear ends of the block, and a T-shaped block 413 is tightly attached to the horizontal end of the L-shaped seat 412, and a vertical groove adapted to the vertical end of the T-shaped block 413 is opened on the horizontal end of the L-shaped seat 412. By arranging the L-shaped seat 412 and the T-shaped block 413, it is convenient to quickly install and disassemble the machine base 3. A limiting groove 414 is opened at the front end of the T-shaped block 413. The height of the limiting groove 414 is the effective distance for the machine base to be lifted and lowered, which is convenient for adjustment according to the diameter of the output shaft of different three-phase asynchronous motors. Fixed blocks 415 are installed at the front and rear ends of the support base 2, and the middle part of the fixed block 415 is threadedly connected with a bolt rod 416 squeezed in the limiting groove 414.

[0040] During operation, when installing the base 3, the center point is adjusted according to the diameter of the output shaft of the three-phase asynchronous motor, and the driving wheel 46 is rotated to drive one of the linkage wheels 44 to rotate. The entire double-headed screw 41 is driven to rotate under the action of the linkage belt 45, so that the moving block 42 moves toward each other in the moving groove 711, so that the inclined blocks 43 on both sides are close to or away from each other through the tapered blocks. Then, when the height adjustment of the base 3 is completed, the base 3 is manually adjusted and moved forward and backward, and then the motor on the base 3 is aligned with the center point. Finally, the T-block 413 is squeezed by the bolt rods 416 on both sides, thereby realizing the front and rear limit and left and right movement of the base 3, which is convenient for installing the output shafts of different three-phase asynchronous motors.

[0041] As an embodiment of the present invention, Figure 3 As shown, rubber pads are installed in the vertical groove of the L-shaped seat 412 and on the inner side of the limiting groove 414, and an expansion spring is sleeved on the outer side of the bolt rod 416 and between the T-block 413 and the fixing block 415. During operation, in order to prevent the vibration generated by the three-phase asynchronous motor during operation from being transmitted between the L-shaped seat 412 and the T-block 413, the friction between the L-shaped seat 412 and the T-block 413 can be increased by arranging the rubber pads. At the same time, the bolt rod 416 on the inner side of the limiting groove 414 can further increase the extrusion pressure, thereby improving the stability of the machine base 3.

[0042] As an embodiment of the present invention, Figure 4 and Figure 5 As shown, the temperature monitoring component 5 includes a bidirectional threaded rod 51, and there are two bidirectional threaded rods 51. The bidirectional threaded rods 51 are threadedly penetrated through the outer side of the machine base 3 and are installed with a driven gear 52. The right end of the machine base 3 is installed with a driving gear 53 meshing with the driven gear 52 through the output shaft of the motor. The right end of the bidirectional threaded rod 51 is threadedly connected with a slider 54, and a C-shaped piece 55 is installed between the sliders 54, and a temperature detector 56 in a ring array is installed at one end of the C-shaped piece 55 close to the motor.

[0043] During operation, when the driving gear 53 rotates, it drives the driven gears 52 that are meshing on both sides, so that the driven gear 52 drives the bidirectional threaded rod 51 to rotate, and the slider 54 makes a linear motion on the base 3. Due to the design of the bidirectional threaded rod 51, the slider 54 makes a reciprocating motion, so that the temperature detector 56 monitors the temperature along each area on the three-phase asynchronous motor, thereby improving the temperature monitoring effect of the three-phase asynchronous motor.

[0044] As an embodiment of the present invention, Figure 6 , Fig. 9 , Fig.10 , Fig.11 and Fig.12As shown, the ball monitoring assembly 6 includes a double-headed I-shaped member 61, which is installed on the right end of the machine base 3, and the right end of the double-headed I-shaped member 61 is rotatably connected to the bearing seat, and the right end of the transmission rod 8 is rotatably connected through the bearing seat, and the front and rear ends of the double-headed I-shaped member 61 are rotatably connected to the V-shaped member 62, and the top of the V-shaped member 62 is rotatably connected to the first roller 63, and a compression spring is installed between the back surface of the bottom end of the V-shaped member 62 and the base 1, and a monitoring box 64 is installed at the top of the base 1 and located on the inner side of the double-headed I-shaped member 61, and a first spring telescopic rod 65 is installed on the top of the monitoring box 64, and a second roller 66 is installed on the top of the first spring telescopic rod 65, and a cross plate 68 is installed on the opposite surface of the bottom end of the V-shaped member 62. Monitoring grooves are provided on the end and top surfaces, a linkage groove is provided on the top of the horizontal plate 68, an L-shaped block 611 is installed on the top of the horizontal plate 68 and in the linkage groove, a first rotating plate 612 is rotatably connected to the top of the horizontal plate 68 and in the linkage groove, a linkage block 614 is slidably connected to the horizontal end of the L-shaped block 611, a second rotating plate 613 rotatably connected to the middle part of the first rotating plate 612 is installed on the top of the linkage block 614, the second rotating plate 613 is rotatably connected to the linkage block 614, a first reset spring 615 is connected between the vertical end of the L-shaped block 611 and the linkage block 614, a squeezing ball is installed at the bottom of the first spring telescopic rod 65 and the top of the first rotating plate 612, and a pressure detector 67 that contacts the squeezing ball is installed in the monitoring groove.

[0045] During operation, after the transmission rod 8 is installed at the output end of the three-phase asynchronous motor, the transmission rod 8 is clamped by the clamping assembly 9, and then the clamping assembly 9 is resisted by the first roller 63 and the second roller 66. When the clamping assembly 9 is in normal operation, the pressure displayed by the pressure detector 67 is a constant value. When radial forces of different strengths appear during the rotation of the three-phase asynchronous motor, the radial force exerted on the first roller 63 rotates upward through the cross plate 68, so that the squeezing ball on the second rotating plate 613 transmits the radial forces of different strengths to the pressure detector 67. After that, the pressure detector 67 transmits the pressure record change data to the terminal, so that the different radial forces of the output shaft of the three-phase asynchronous motor can be monitored for maintenance personnel to perform maintenance on it.

[0046] As an embodiment of the present invention, Figure 6 and Fig.10 As shown, the center monitoring assembly 7 includes a cross-shaped rod 71, which is slidably connected to the left end of the double-headed I-shaped member 61, and the right end of the cross-shaped rod 71 is sleeved with a second return spring 72. The left end of the cross-shaped rod 71 is rotatably connected to the center rod 74, and the front end of the center rod 74 is rotatably connected to the square block 75. A telescopic member 76 is installed in the middle of the square block 75 to extend or shorten the length of the square block 75. At the same time, in order to protect the support, a pointer is installed at the end of the first spring telescopic rod 65 away from the double-headed I-shaped member 61.

[0047] Before installing the three-phase asynchronous motor, rotate the center rod 74 downward until the pointer on the square block 75 is aligned with the three-phase asynchronous motor. When the center point of the three-phase asynchronous motor and the pointer are not at the same point, adjust the displacement on the base 3 until the three-phase asynchronous motor and the pointer are at the same point, so that the output shafts of three-phase asynchronous motors with different diameters on the market can be in a straight line with the clamping assembly 9, so as to monitor the concentricity of the three-phase asynchronous motor and improve the monitoring effect of the three-phase asynchronous motor.

[0048] As an embodiment of the present invention, Figure 7 and Figure 8 As shown, a receiving groove 73 is provided on the left side of the double-headed I-beam 61, and the length of the receiving groove 73 is equal to the length of the center rod 74. A movable groove 711 is provided on the top of the left end of the double-headed I-beam 61 and corresponds to the top of the cross-shaped rod 71. A limiting rod 712 sliding on the inner side of the movable groove 711 is installed on the top of the cross-shaped rod 71. The top of the limiting rod 712 is rotatably connected with a clamping plate 713. A clamping groove matched with the clamping plate 713 is provided on the top of the double-headed I-beam 61.

[0049] During operation, when the center monitoring component 7 ends, the square block 75 is retracted into the telescopic member 76, and then the telescopic member 76 is rotated to the side of the center rod 74, and then the card plate 713 is disengaged from the card slot. Under the action of the second reset spring 72, the cross-shaped rod 71 drives the center rod 74 to move to the right until the center rod 74 enters the storage slot 73, so as to have a storage effect on the pointer.

[0050] As an embodiment of the present invention, Fig.12 , Fig.13 and Fig.15 As shown, the clamping assembly 9 includes a circular cylinder 91, which is in contact between the first roller 63 and the second roller 66. Semi-arc blocks 92 are installed at the left and right ends of the circular cylinder 91. A control rod 93 is rotatably connected to the middle of the semi-arc block 92. A torsion gear 95 is installed on the outer wall of the control rod 93 and located inside the semi-arc block 92. Transmission grooves are provided at the upper and lower ends of the inner side of the semi-arc block 92. L-shaped pieces 94 are slidably connected to the upper and lower ends of the semi-arc block 92. A horizontal end of the L-shaped piece 94 and located inside the transmission groove are installed. The gear teeth meshing with the torsion gear 95, the vertical end of the L-shaped member 94 is equipped with a second spring telescopic rod 96, the telescopic rod of the second spring telescopic rod 96 is slidably penetrated through the inner side of the circular cylinder 91 and is equipped with an extrusion cone block 97, and anti-slip grooves are provided on the extrusion cone block 97 and the semi-arc block 92. The outer wall of the transmission rod 8 and the inner side of the circular cylinder 91 are provided with an anti-slip pad, which is beneficial to increase the friction force of the extrusion cone block 97 and the semi-arc block 92 on the transmission rod 8 to prevent the transmission rod 8 from slipping during rotation.

[0051] During operation, when the transmission rod 8 passes through the middle of the clamping assembly 9, the rotating control rod 93 rotates, so that the torsion gear 95 drives the L-shaped parts 94 on the upper and lower sides to move towards each other. At the same time, through the action of the second spring telescopic rod 96, the extrusion cone block 97 squeezes the outer wall of the transmission rod 8 until the transmission rod 8 contacts the semi-arc block 92, so that the circular cylinder 91 and the transmission rod 8 rotate synchronously.

[0052] As an embodiment of the present invention, Fig.13 and Fig.14 As shown, the clamping assembly 9 also includes an inclined slide rail 911, which is installed on the inner bottom wall of the circular cylinder 91. Two fixed seats 912 are installed in the middle of the torsion gear 95. A first gear 913 is installed on the outer side of the torsion gear 95 and between the two fixed seats 912. A screw rod 914 is rotatably connected between the two fixed seats 912. A second gear 915 meshing with the first gear 913 is installed in the middle of the screw rod 914. Nuts 916 are threadedly connected to both ends of the screw rod 914. The two nuts 916 The opposite back side is rotatably connected to a slider seat 917 that is slidably connected to the inclined slide rail 911. The top of the slider seat 917 is connected to an extrusion plate 918 through a slide rail connection. The left end of the torsion gear 95 is rotatably passed through the outside of the semi-arc block 92 and is threadedly connected with a double bolt 98. The rear end of the double bolt 98 and the outside of the torsion gear 95 are sleeved with an anti-loosening pad. By arranging the double bolt 98 and the anti-loosening pad, the torsion gear 95 can be prevented from becoming unstable during the rotation of the clamping assembly 9, thereby further improving the stability of the torsion gear 95.

[0053] During operation, when the torsion gear 95 rotates, it drives the first gear 913 and the second gear 915 to rotate. The second gear 915 mobilizes the screw rod 914 to rotate synchronously. As the nut 916 moves toward each other under the action of the rotation of the screw rod 914, it drives the slider seat 917 to move up and down along the inclined slide rail 911, thereby realizing the lifting and lowering movement of the extrusion plate 918, which is beneficial for the extrusion plate 918 to be closely connected to the middle part of the transmission rod 8, further improving the clamping effect of the transmission rod 8.

[0054] The present invention further provides a three-phase asynchronous motor, which is monitored by using the above-mentioned full-phase reactive power compensation device, and the three-phase asynchronous motor is mounted on a machine base 3 .

[0055] Working principle: This full-phase reactive power compensation device for three-phase asynchronous motors is used:

[0056] Firstly, during the installation of the base 3, the center point is adjusted according to the diameter of the output shaft of the three-phase asynchronous motor, the driving wheel 46 is rotated to drive one of the linkage wheels 44 to rotate, and the entire double-headed screw 41 is driven to rotate under the action of the linkage belt 45, so that the moving block 42 moves towards each other in the moving groove 711, so that the inclined blocks 43 on both sides are close to or away from each other through the tapered blocks. Then, when the height adjustment of the base 3 is completed, the base 3 is manually adjusted and moved forward and backward, and then the motor on the base 3 is aligned with the center point, and finally the T-block 413 is squeezed by the bolt rods 416 on both sides, thereby realizing the front and rear limit and left and right movement of the base 3, which is convenient for the installation of the output shafts of different three-phase asynchronous motors.

[0057] 2. Secondly, after the transmission rod 8 is installed at the output end of the three-phase asynchronous motor, the transmission rod 8 is clamped by the clamping assembly 9, and then the clamping assembly 9 is resisted by the first roller 63 and the second roller 66. When the clamping assembly 9 is in normal operation, the pressure displayed by the pressure detector 67 is a constant value. When radial forces of different strengths appear during the rotation of the three-phase asynchronous motor, the radial force exerted on the first roller 63 rotates upward through the cross plate 68, so that the squeezing ball on the second rotating plate 613 transmits the radial forces of different strengths to the pressure detector 67. After that, the pressure detector 67 transmits the pressure record change data to the terminal, so that the different radial forces of the output shaft of the three-phase asynchronous motor can be monitored for maintenance personnel to perform maintenance.

[0058] 3. When the transmission rod 8 passes through the middle of the clamping assembly 9, the rotating control rod 93 rotates, so that the torsion gear 95 drives the L-shaped parts 94 on the upper and lower sides to move toward each other. At the same time, under the action of the second spring telescopic rod 96, the extrusion cone block 97 squeezes the outer wall of the transmission rod 8 until the transmission rod 8 contacts the semi-arc block 92, so that the circular cylinder 91 and the transmission rod 8 rotate synchronously. When the torsion gear 95 rotates, it drives the first gear 913 and the second gear 915 to rotate. The second gear 915 mobilizes the screw rod 914 to rotate synchronously. As the nut 916 realizes the opposite movement under the action of the rotation of the screw rod 914, it drives the slider seat 917 to move up and down along the inclined slide rail 911, thereby realizing the lifting and lowering movement of the extrusion plate 918, which is conducive to the extrusion plate 918 being closely connected to the middle part of the transmission rod 8.

[0059] 4. When the driving gear 53 rotates, it drives the driven gears 52 that mesh with each other on both sides, so that the driven gear 52 drives the bidirectional threaded rod 51 to rotate, and the slider 54 moves linearly on the base 3. Due to the design of the bidirectional threaded rod 51, the slider 54 moves back and forth, so that the temperature detector 56 monitors the temperature along each area of ​​the three-phase asynchronous motor.
