Description

Technical Field

[0001] This invention relates to the field of three-phase motors, and more particularly to an energy-saving three-phase motor with high safety performance. Background Technology

[0002] In practical applications of three-phase motors, to ensure stable operation, a filter device is usually required to prevent external impurities from entering the motor and causing wear or short circuits in critical components such as motor windings and bearings. However, after prolonged operation, the filter device will gradually accumulate a large amount of impurities, leading to a decrease in filtration efficiency, affecting the motor's heat dissipation and normal operation, and may even cause safety accidents.

[0003] Currently, common methods for cleaning filter devices have significant shortcomings. On the one hand, many motors employ a shutdown cleaning method, meaning that when the filter device becomes clogged to a certain extent, the motor must be stopped, and the filter device disassembled for cleaning or replacement. This method not only interrupts the production process and reduces production efficiency but also increases labor and time costs. On the other hand, while existing online cleaning technologies can achieve cleaning without shutting down the machine to some extent, they often suffer from incomplete cleaning. Some cleaning methods can only clean localized areas of the filter device, leaving some hidden parts without effectively removing impurities. Over time, this accumulation can still adversely affect motor performance. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a high-safety, energy-saving three-phase motor. In practical use, this motor can achieve self-cleaning of the filter section. This self-cleaning can be performed while the device is running without stopping the machine, and the cleaning is comprehensive.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A high-safety, energy-saving three-phase motor includes a motor body, a first connecting ring fixedly connected to the right side of the motor body, a second connecting ring disposed to the right of the first connecting ring, the first and second connecting rings being fixedly connected by multiple U-shaped connecting plates, an annular groove being provided on the outer sides of the first and second connecting rings, an annular mesh being disposed within the annular groove, a drive shaft being installed inside the motor body, the right end of the drive shaft extending into the interior of the first connecting ring, and multiple axial flow fan blades being installed thereon; a cleaning mechanism, comprising two vertical plates respectively fixedly connected to the inner sides of the first and second connecting rings, an arc-shaped hollow plate being fixedly connected to the upper ends of the two vertical plates, the inner side of the arc-shaped hollow plate having multiple spray holes; a gas-liquid injection mechanism for injecting liquid and gas into the interior of the arc-shaped hollow plate; and an impact mechanism for vibrating the annular mesh to improve the cleaning effect.

[0007] Preferably, the gas-liquid injection mechanism includes a mounting plate fixedly connected to the right side of the second connecting ring, a first piston cylinder fixedly connected to the right side of the mounting plate, a first electromagnet fixedly connected to the bottom inner part of the first piston cylinder, a first piston plate that can slide up and down inside the first piston cylinder, the lower end of the first piston plate being elastically connected to the first electromagnet via a first spring, the first piston plate being magnetic, and the first electromagnet repelling the adjacent surfaces of the first piston plate when energized.

[0008] Preferably, a controller is installed at the upper end of the motor body, and a mounting rod is fixedly connected to the inner side of the first connecting ring. A gas flow rate sensor is installed at the end of the mounting rod. The gas flow rate sensor cooperates with the controller to realize the control of the first electromagnet.

[0009] Preferably, the bottom space of the first piston cylinder is connected to an air inlet, a liquid inlet pipe, and a discharge pipe. The other end of the discharge pipe extends into the arc-shaped hollow plate. One-way valves are installed inside the air inlet, the liquid inlet pipe, and the discharge pipe. The one-way valves inside the air inlet and the liquid inlet pipe are used to enable one-way external entry into the bottom of the first piston cylinder. The flow direction of the one-way valve inside the discharge pipe is one-way entry into the arc-shaped hollow plate from the first piston cylinder.

[0010] Preferably, the lower ends of the first connecting ring and the second connecting ring are fixedly connected to an arc-shaped connecting strip, and the upper end of the arc-shaped connecting strip is provided with an arc-shaped water collection groove, the inner bottom of which is connected to a sewage pipe.

[0011] Preferably, a rotating shaft is horizontally disposed through the mounting plate, the rotating shaft is rotatably connected to the mounting plate, a second gear is fixedly connected to the left end of the rotating shaft, an internal gear ring is fixedly connected to the inner side of the annular mesh, the second gear meshes with the internal gear ring, a first gear is mounted on the right end of the rotating shaft through a one-way bearing, a rectangular opening is provided at the top inner part of the first piston cylinder, a rack is fixedly connected to the upper end of the first piston plate, the upper end of the rack passes through the rectangular opening and meshes with the first gear.

[0012] Preferably, the impact mechanism includes a second piston cylinder fixedly connected to the bottom of the arc-shaped water collection tank. A second electromagnet is fixedly connected to the bottom of the second piston cylinder. A magnetic plate that can slide up and down is provided inside the second piston cylinder. The magnetic plate and the second electromagnet are elastically connected by a second spring. An impact rod is fixedly connected to the upper end of the magnetic plate. The upper end of the impact rod passes through the top of the inner part of the second piston cylinder and cooperates with the annular mesh. When the second electromagnet is energized, it attracts the adjacent surfaces of the magnetic plate with opposite polarities.

[0013] Preferably, a plurality of guide strips are provided through the rack, and both sides of the plurality of guide strips protrude from the sides of the rack. A grounding block is installed on both the left and right sides of the rectangular opening, and the grounding block cooperates with the second electromagnet.

[0014] Compared with the prior art, the beneficial effects of this invention are as follows:

[0015] 1. After the motor body starts, the drive shaft drives the axial fan blades to rotate, generating airflow from right to left to achieve active heat dissipation. This design effectively reduces the motor's operating temperature, ensuring the motor body operates normally in a suitable temperature environment, extending the motor's service life, and improving the stability of motor operation.

[0016] 2. A gas flow rate sensor monitors the internal gas flow rate in real time. When the annular mesh becomes clogged and the flow rate falls below the threshold, the controller activates the first electromagnet to reverse-flushing and drying the annular mesh with water and gas. This system can promptly detect and address blockages, ensuring unobstructed heat dissipation channels for the motor and maintaining its normal heat dissipation performance.

[0017] 3. When the first piston plate moves up and down, the annular mesh rotates in one direction through the cooperation of components such as the rack and pinion and the first gear. In this way, different parts of the annular mesh can be rinsed sequentially during the cleaning process, avoiding the problem of incomplete cleaning in certain areas, ensuring that all parts of the annular mesh are effectively cleaned, and improving the overall cleaning effect.

[0018] 4. During the downward movement of the rack and pinion, which sprays water and air, the guide bar intermittently energizes the second electromagnet, causing the impact rod to strike the annular mesh. This vibration helps to dislodge blockages from the annular mesh more easily, further enhancing the unblocking effect, ensuring the ventilation performance of the annular mesh, and guaranteeing the motor's heat dissipation efficiency.

[0019] 5. The arc-shaped water collection tank and sewage pipe effectively collect and discharge the wastewater generated by the backwashing ring net. This prevents wastewater from flowing freely and polluting the surrounding environment, and also facilitates centralized wastewater treatment.

[0020] 6. During the normal operation of the motor body, the first electromagnet can be switched on and off multiple times simultaneously to achieve comprehensive cleaning of the ring network. Cleaning can be completed without stopping the machine, reducing production interruptions caused by downtime for cleaning, improving production efficiency, and lowering operating costs.

[0021] In summary, this motor achieves efficient heat dissipation during use. In addition, it can automatically and thoroughly clean the filter, ensuring heat dissipation performance, avoiding increased energy consumption due to filter clogging, and improving overall safety and stability.

Detailed Implementation

[0032] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

[0033] Reference Figures 1-9 A high-safety, energy-saving three-phase motor includes a motor body 1. A first connecting ring 9 is fixedly connected to the right side of the motor body 1, and a second connecting ring 4 is provided to the right of the first connecting ring 9. The first connecting ring 9 and the second connecting ring 4 are fixedly connected by multiple U-shaped connecting plates 8. An annular groove 6 is provided on the outer side of the first connecting ring 9 and the second connecting ring 4. An annular mesh 7 is provided in the annular groove 6. A drive shaft is installed inside the motor body 1. The right end of the drive shaft extends into the first connecting ring 9 and is equipped with multiple axial flow fan blades 37. After the motor body 1 is started, the multiple axial flow fan blades 37 rotate, generating an airflow from right to left.

[0034] As one embodiment of the present invention, it also includes a cleaning mechanism, which includes two vertical plates 17 that are respectively fixedly connected to the inner sides of the first connecting ring 9 and the second connecting ring 4. The upper ends of the two vertical plates 17 are jointly fixedly connected to an arc-shaped hollow plate 35, and a plurality of spray holes 18 are opened on the inner side of the arc-shaped hollow plate 35.

[0035] As one embodiment of the present invention, it also includes a gas-liquid injection mechanism for injecting liquid and gas into the interior of the arc-shaped hollow plate 35. The gas-liquid injection mechanism includes a mounting plate 5 fixedly connected to the right side of the second connecting ring 4. A first piston cylinder 10 is fixedly connected to the right side of the mounting plate 5. A first electromagnet 25 is fixedly connected to the bottom of the inner part of the first piston cylinder 10. A first piston plate 23 that can slide up and down is provided inside the first piston cylinder 10. The lower end of the first piston plate 23 is elastically connected to the first electromagnet 25 through a first spring 24. The first piston plate 23 is magnetic. When the first electromagnet 25 is energized, it repels the adjacent surfaces of the first piston plate 23 due to their similar polarity.

[0036] In one embodiment of the present invention, the inner bottom space of the first piston cylinder 10 is connected to an air inlet 16, a liquid inlet pipe 14, and a discharge pipe 15. The liquid inlet pipe 14 is connected to an external water tank for pumping water in. The other end of the discharge pipe 15 extends into the arc-shaped hollow plate 35. One-way valves are installed inside the air inlet 16, the liquid inlet pipe 14, and the discharge pipe 15. The one-way valves inside the air inlet 16 and the liquid inlet pipe 14 are used to enable one-way external entry into the inner bottom of the first piston cylinder 10. The flow direction of the one-way valve inside the discharge pipe 15 is one-way entry of the first piston cylinder 10 into the arc-shaped hollow plate 35.

[0037] In one embodiment of the present invention, a controller 2 is installed on the upper end of the motor body 1, and an installation rod 36 is fixedly connected to the inner side of the first connecting ring 9. A gas flow rate sensor 38 is installed at the end of the installation rod 36. The gas flow rate sensor 38 cooperates with the controller 2 to control the first electromagnet 25. When the annular mesh 7 is blocked, the internal gas flow rate will be lower than the threshold. The controller 2 controls the first electromagnet 25 to be energized for a period of time and then de-energized. This action is repeated multiple times. With the use of the first spring 24, the first piston plate 23 can move up and down multiple times. When the first piston plate 23 moves up, water and gas will be drawn in. The gas will be located in the top space of the space below the first piston plate 23 with the first piston cylinder 10. When released later, water will be released first and then gas will be released. The release of water realizes the reverse flushing of the annular mesh 7, while the release of gas can dry it for subsequent use.

[0038] In one embodiment of the present invention, the lower ends of the first connecting ring 9 and the second connecting ring 4 are fixedly connected to an arc-shaped connecting strip 19. An arc-shaped water collection trough 20 is provided at the upper end of the arc-shaped connecting strip 19. A sewage pipe 21 is connected to the bottom of the arc-shaped water collection trough 20. Wastewater can be collected by using the arc-shaped water collection trough 20.

[0039] In one embodiment of the present invention, a rotating shaft 11 is horizontally disposed on the mounting plate 5, and the rotating shaft 11 is rotatably connected to the mounting plate 5. A second gear 29 is fixedly connected to the left end of the rotating shaft 11, and an internal gear ring 30 is fixedly connected to the inner side of the annular mesh 7. The second gear 29 meshes with the internal gear ring 30. A first gear 12 is mounted on the right end of the rotating shaft 11 through a one-way bearing. By utilizing the one-way bearing, when the first piston plate 23 moves upward, the meshing of the rack 13 and the first gear 12 can cause the rotating shaft 11 to rotate, thereby causing the second gear 29 to drive the internal gear ring 30 to rotate. The first piston plate 23 moves up and down, causing the annular mesh 7 to rotate. When the upper rack 13 moves down, it will not drive the rotating shaft 11 to rotate. In this way, when the first piston plate 23 moves up and down once, the rotating shaft 11 will drive the annular mesh 7 to rotate once in one direction. The top of the inner part of the first piston cylinder 10 is provided with a rectangular opening 26. The upper end of the first piston plate 23 is fixedly connected to the rack 13. The front side of the rack 13 is provided with a guide groove. The front side wall of the rectangular opening 26 is provided with a guide block that cooperates with the guide groove. The upper end of the rack 13 passes through the rectangular opening 26 and meshes with the first gear 12.

[0040] As one embodiment of the present invention, an impact mechanism is also included. This impact mechanism is used to vibrate the annular mesh 7, improving the cleaning effect. The impact mechanism includes a second piston cylinder 22 fixedly connected to the bottom of the arc-shaped water collection tank 20. A second electromagnet 33 is fixedly connected to the bottom of the second piston cylinder 22. A magnetic plate 31 that can slide up and down is provided inside the second piston cylinder 22. The magnetic plate 31 and the second electromagnet 33 are elastically connected by a second spring 32. An impact rod 34 is fixedly connected to the upper end of the magnetic plate 31. The upper end of the impact rod 34 penetrates the top of the inner part of the second piston cylinder 22 and cooperates with the annular mesh 7. When the second electromagnet 33 is energized, it attracts the adjacent surfaces of the magnetic plate 31 with opposite polarities. The rack 1... Multiple guide strips 28 are arranged through the rack 13. Both sides of the guide strips 28 protrude from the sides of the rack 13. Electrical blocks 27 are installed on the left and right sides of the rectangular opening 26. The electrical blocks 27 cooperate with the second electromagnet 33. A power module (not shown) is also included. The positive terminal of the power module is electrically connected to the left electrical block 27. The negative terminal of the power module, the second electromagnet 33, and the right electrical blocks 27 are electrically connected in sequence. In this way, the second electromagnet 33 can be intermittently energized during the downward movement of the rack 13, that is, during the water spraying and air jetting process. With the use of the second spring 32, the impact rod 34 can repeatedly impact the area to be cleaned in the annular mesh 7. The vibration makes it easier to clear the blockage.

[0041] In this invention, after the motor body 1 is started, its internal drive shaft rotates, which drives multiple axial flow fan blades 37 installed on the right end of the drive shaft and located inside the first connecting ring 9 to rotate, generating airflow from right to left to achieve active heat dissipation and ensure the normal use of the motor body 1.

[0042] A gas flow rate sensor 38, installed at the end of the mounting rod 36 inside the first connecting ring 9, monitors the internal gas flow rate in real time and transmits the data to the controller 2 installed on the upper end of the motor body 1. When the ring network 7 is not blocked, the gas flow rate is normal, the controller 2 does not issue a command, and the first electromagnet 25 is in a de-energized state.

[0043] When the ring network 7 becomes blocked, causing the internal gas flow rate to fall below the threshold, the gas flow rate sensor 38 transmits a signal to the controller 2. The controller 2 controls the first electromagnet 25 to be energized for a period of time, then de-energized, and repeats this action multiple times. When energized, the first electromagnet 25 and the adjacent surfaces of the magnetic first piston plate 23 repel each other due to their similar polarity. Under the action of repulsion, the first piston plate 23 overcomes the elastic force of the first spring 24 and moves upward. When the first piston plate 23 moves upward, a negative pressure is formed in the bottom space inside the first piston cylinder 10. External water enters the bottom of the first piston cylinder 10 through the inlet pipe 14 (which is connected to the external water tank) and the internal one-way valve. At the same time, external gas enters the top space below the first piston plate 23 at the bottom of the first piston cylinder 10 through the air inlet 16 and the internal one-way valve. After a period of time, the controller 2 controls the first electromagnet 25 to be de-energized, and the first piston plate 23 moves down under the elastic force of the first spring 24, pushing the water at the bottom of the first piston cylinder 10 into the arc-shaped hollow plate 35 through the discharge pipe 15 (the other end of the discharge pipe 15 extends into the arc-shaped hollow plate 35) and the internal one-way valve. Subsequently, the gas also enters the arc-shaped hollow plate 35 through the same path.

[0044] Water and gas entering the arc-shaped hollow plate 35 are sprayed out through multiple spray holes 18 opened on the inner side of the arc-shaped hollow plate 35. The water washes the ring net 7 in reverse to remove blockages. Then the gas is sprayed out to dry the washed ring net 7, making it convenient for subsequent use.

[0045] When the first piston plate 23 moves upward, the rack 13 moves upward and meshes with the first gear 12, driving the rotating shaft 11 to rotate. This, in turn, causes the second gear 29 to drive the internal gear ring 30 to rotate, thus rotating the annular mesh 7. When the first piston plate 23 moves downward, the rack 13 moves downward, but due to the one-way bearing, it does not drive the rotating shaft 11 to rotate. Thus, for each up-and-down movement of the first piston plate 23, the rotating shaft 11 drives the annular mesh 7 to rotate once in one direction.

[0046] During the downward movement of rack 13 (i.e., the water spraying and air aspiration process), guide bar 28 alternately contacts left and right contact blocks 27, causing the second electromagnet 33 to be intermittently energized. After the second electromagnet 33 is energized, it attracts the opposite polarity of the adjacent surfaces of magnetic plate 31, causing magnetic plate 31 to move downward, compressing the second spring 32, and causing impact rod 34 to move downward accordingly; when the second electromagnet 33 is de-energized, magnetic plate 31 moves upward under the elastic force of the second spring 32, and impact rod 34 moves upward to strike the area to be cleaned on the annular mesh 7, using vibration to make it easier to clear blockages;

[0047] The lower ends of the first connecting ring 9 and the second connecting ring 4 are fixedly connected to the arc-shaped connecting strip 19. An arc-shaped water collection trough 20 is opened at the upper end of the arc-shaped connecting strip 19. The bottom of the arc-shaped water collection trough 20 is connected to the sewage pipe 21. The wastewater generated by the reverse flushing of the ring net 7 falls into the arc-shaped water collection trough 20 and is discharged and collected through the sewage pipe 21. It is worth mentioning that after the first electromagnet 25 is switched on and off multiple times, the ring net 7 can be thoroughly cleaned, ensuring the comprehensiveness of the cleaning. This action can be synchronized with the normal operation of the motor body 1 without stopping the machine for cleaning.

[0048] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
