Description

Technical Field

[0001] The invention relates to the technical field of brushless generators, in particular to a small brushless generator. Background Art

[0002] A brushless generator is a new type of generator based on electronic control technology, also called a permanent magnet synchronous generator, which consists of permanent magnets, rotors, stators, end covers, etc. During operation, the magnetic field generated by the permanent magnets will act on the rotor, causing the rotor to start rotating and generating a three-phase potential difference on the stator. These potential differences are then output as stable alternating current through an electronic controller. At the same time, the electronic controller will also control parameters such as the motor's speed and power output to ensure its normal operation. During use, brushless generators often choose different sizes of brushless generators (such as large brushless generators or small brushless generators) according to the use environment.

[0003] At present, during the use of small brushless generators, due to their small size, the corresponding heat dissipation structure design will also be limited, making it difficult to achieve the best heat dissipation effect. Therefore, during the long-term operation of the small brushless generator, a large amount of heat will be generated, and the heat dissipation is slow, which makes the temperature of the small brushless generator too high, causing aging of the component materials in the small brushless generator, shortening its service life, and the lubrication effect of the drive end located on the outside is deteriorated in a high temperature environment. At the same time, dust is easily accumulated, resulting in poor transmission effect of the drive end, affecting the normal operation of the small brushless generator, thereby worsening the use effect of the small brushless generator.

When the brushless generator body 1 is working, the driving shaft 4 and the driving wheel 5 are driven to rotate synchronously through the driving impeller 13 to facilitate transmission and power generation, and the breathable round frame 2 cooperates with the sealing plate 3 to be sleeved on the driving impeller 13, which can prevent foreign objects from contacting and colliding with the driving impeller 13, avoid affecting the rotation of the driving impeller 13, and also facilitate the discharge of hot air to ensure the stable operation of the brushless generator body 1, and a pair of liquid storage frames 9 are arranged on the outer wall of the brushless generator body 1, and cooperate with the carbon dioxide aqueous solution to conduct heat and heat conduction and dissipation of the heat generated by the brushless generator body 1 when it is working, so as to facilitate the stable operation of the brushless generator body 1.

[0035] like Figure 1 , Figure 3 and Figure 5 As shown, the cleaning mechanism 6 includes a ring 601 sleeved on the outer wall of the driving shaft 4, a pair of connecting plates 602 are fixedly connected to the outer wall of the ring 601, and the ends of the pair of connecting plates 602 close to the sealing plate 3 are fixedly connected to the mounting plate 603, the ends of the pair of mounting plates 603 close to each other are fixedly connected to the cleaning brush 604, and the outer walls of the pair of cleaning brushes 604 are in contact with the outer wall of the air-permeable circular frame 2, an oil collecting and filtering mechanism 8 is installed between the outer wall of the sealing plate 3 and the outer wall of the pair of mounting plates 603, and a liquid-discharging mechanism 10 is fixedly connected between the ends of the pair of mounting plates 603 away from each other and the inside of the pair of liquid storage frames 9. The pair of connecting plates 602 drive the pair of cleaning brushes 604 to rotate along the outer wall of the air-permeable circular frame 2 by the rotation of the driving shaft 4, so as to clean the dust and impurities attached to the outer wall of the air-permeable circular frame 2, reduce blockage, ensure the circulation of air, and avoid the accumulation of dust and impurities to accelerate aging and wear, thereby preventing the air-permeable circular frame 2 from blocking foreign body collision from becoming worse.

[0036] like Figure 1 and Figure 3-Figure 4As shown, the oil filling mechanism 7 includes an oil storage sac 701 fixedly connected to one end of the sealing plate 3, a connecting tube 702 is fixedly connected to the top of the oil storage sac 701, and a liquid outlet pipe 703 is fixedly connected to the bottom end of the oil storage sac 701, and a pair of first rubber sealing sheets 708 are rotatably connected to the inner wall of the liquid outlet pipe 703, a pair of straight plates 704 are fixedly connected to the end of the sealing plate 3 away from the breathable circular frame 2, and the ends of the pair of straight plates 704 close to each other are both installed with electric telescopic rods 706, and the ends of the pair of electric telescopic rods 706 close to each other are fixedly connected with extrusion plates 707, and the ends of the pair of extrusion plates 707 close to each other are in contact with the outer wall of the oil storage sac 701, and a timer 705 is installed at the end of the straight plate 704 on one side away from the electric telescopic rod 706, and the timer 705 is electrically connected to the electric telescopic rod 706. The timer 705 runs synchronously with the brushless generator body 1. After the brushless generator body 1 has been working for a period of time, the drive shaft 4 and the drive wheel 5 continue to rotate, which increases the temperature between the drive shaft 4 and the bearing, and the corresponding lubrication effect becomes worse.

Through the setting of the sealing plug 7021, after the lubricating oil is added to the oil filling port, it is sealed, so that impurities are not easy to enter the connecting tube 702 and the oil storage capsule 701, avoiding contamination thereof.

[0038] like Figure 1 , Figure 3 ,and Figure 5-Figure 6As shown, the oil collecting and filtering mechanism 8 includes a collecting box 801 fixedly connected to the outer wall of the sealing plate 3, a filter screen 802 is fixedly connected to the inner wall of the collecting box 801, a plurality of fixed hemispheres 803 are fixedly connected to the bottom end of the collecting box 801, a pair of outer walls of the mounting plates 603 are embedded with straight cylinders 804, and the interior of the straight cylinders 804 is slidably connected with a T-shaped movable rod 805, a pair of straight cylinders 804 are each provided with through holes at the ends close to each other, and a pair of T-shaped movable rods 805 are each passed through the through holes at the ends close to each other and are fixedly connected with a movable hemisphere 806, the movable hemisphere 806 is in contact with the fixed hemisphere 803, and a first spring 807 is fixedly connected between the end of the T-shaped movable rod 805 away from the movable hemisphere 806 and the inner wall of the straight cylinder 804. During the downward flow of the lubricating oil released by squeezing the oil storage bag 701, it does not stay at the contact point between the driving shaft 4 and the bearing, but continues to flow downward. It can be collected by the collecting box 801 and filtered with the filter 802 to ensure the cleanliness of the lubricating oil collection and reduce the waste of resources. A pair of straight cylinders 804 and T-shaped movable rods 805 rotate together with the mounting plate 603, driving the movable hemisphere 806 to repeatedly contact and collide with the fixed hemisphere 803 and the collecting box 801 with the assistance of the first spring 807 and the T-shaped movable rod 805, generating vibration, so that the impurities blocked on the surface of the filter 802 are dispersed under the action of vibration, and are not easy to gather together and cause clogging of the mesh.

[0039] like Figure 1 and Figure 7-Figure 8 As shown, a pair of liquid-discharging mechanisms 10 each include a rotating convex rod 1001, the outer wall of the rotating convex rod 1001 is fixedly connected to one end of the mounting plate 603 away from the cleaning brush 604, a pair of liquid storage frames 9 are each provided with a movable rod 1003 inside, and the outer wall of the movable rod 1003 is fixedly connected to a plurality of stirring paddles 1006, the inner walls of the pair of liquid storage frames 9 are each drilled with circular holes, and one end of the movable rod 1003 close to the rotating convex rod 1001 passes through the circular holes and is fixedly connected to an arc block 1002, the rotating convex rod 1001 and the arc block 1002 are in contact, the outer wall of the movable rod 1003 is sleeved with a second spring 1004, and the two ends of the second spring 1004 are respectively fixedly connected to the opposite sides of the liquid storage frame 9 and the arc block 1002.

The carbon dioxide content in the carbon dioxide aqueous solution is 80%, so that the moist carbon dioxide overflows from the aqueous solution under the stirring action, and the heat is driven to dissipate outwards with the help of the flow of gas, thereby accelerating the heat dissipation.

[0040] like Figure 8 As shown, the inner wall of the circular hole is fixedly connected with a sealing ring 1005, and the inner wall of the sealing ring 1005 is in close contact with the outer wall of the movable rod 1003. By setting the sealing ring 1005, the gap between the circular hole and the movable rod 1003 is sealed, so that the carbon dioxide aqueous solution is not easy to penetrate outward, and the sealing performance is enhanced.

[0041] like Figure 1 , Figure 7 and Fig.10 As shown, a pair of liquid storage frames 9 are fixedly connected to a liquid inlet pipe 901 at one end away from each other, and a control valve 902 is installed on the outer wall of the liquid inlet pipe 901.

The humid carbon dioxide gas overflows outward and enters into the multiple telescopic airbag columns 1104, causing them to extend upward, thereby allowing the humid carbon dioxide gas to fully contact the heat at the brushless generator body 1. The humid carbon dioxide gas contains corresponding water vapor inside, which evaporates into water vapor through the evaporation heat absorption effect, while absorbing heat and reducing the temperature at the brushless generator body 1, achieving the effect of heat absorption and cooling, and reducing the impact of high temperature.

[0043] like Figure 1 and Figure 10-11As shown, a pair of cold air release mechanisms 12 each include a lifting plate 1201 fixedly connected to the rear end of the top plate 1106, a rectangular frame 12011 is fixedly connected to the top of the liquid storage frame 9, and a mounting tube 1204 is fixedly connected to the top of the rectangular frame 12011, and a through hole is drilled at the top of the mounting tube 1204, and a round rod 1202 is fixedly connected to the bottom end of the lifting plate 1201, and the bottom end of the round rod 1202 extends through the through hole to the inside of the mounting tube 1204 and is fixedly connected to a pressing plate 1205, a control switch 1206 is installed at the inner top end of the mounting tube 1204, and the bottom end of the control switch 1206 is in contact with the top end of the pressing plate 1205, and the outer wall of the round rod 1202 is sleeved with a third spring 1203, and the top and bottom ends of the third spring 1203 are respectively It is fixedly connected to the bottom end of the lifting plate 1201 and the top end of the mounting tube 1204, the inner wall of the mounting tube 1204 is slidably connected with a transparent piston plate 1208, and a flashing indicator light 1207 is installed on the top end of the transparent piston plate 1208, the inner wall of the mounting tube 1204 is fixedly connected with a deformation memory telescopic rod 1209 through a cross plate, and the top end of the deformation memory telescopic rod 1209 is fixedly connected to the bottom end of the transparent piston plate 1208, the deformation memory telescopic rod 1209 matches the light of the flashing indicator light 1207, and the initial state of the deformation memory telescopic rod 1209 is an extended state, a refrigerator 12010 is installed inside the rectangular frame 12011, and the flashing indicator light 1207 and the refrigerator 12010 are both electrically connected to the control switch 1206.

The deformation memory telescopic rod 1209 is made of a photosensitive shape memory polymer material and has a memory effect. Under the influence of the light of the flashing indicator light 1207, the deformation memory telescopic rod 1209 deforms and contracts, pulling the transparent piston plate 1208 to move downward, squeezing the cold air inside the rectangular frame 12011 and the mounting cylinder 1204 to flow into the liquid storage frame 9, and interacting with the heat inside. The temperature of the liquid storage frame 9 is lowered by alternating between hot and cold. When the light of the flashing indicator light 1207 goes out, the deformation memory telescopic rod 1209 is reset and extended, driving the transparent piston plate 1208 to reset upward. When the light of the flashing indicator light 1207 comes on next time, the transparent piston plate 1208 is driven again to squeeze the cold air into the liquid storage frame 9, causing the inside of the liquid storage frame 9 to be in a low temperature state. At the same time, part of the cold air flows into the multiple telescopic airbag columns 1104 along with the moist carbon dioxide. As a result, surrounded by the liquid storage frames 9 on both sides and the multiple telescopic airbag columns 1104 on the top, multiple areas around the brushless generator body 1 are wrapped with cold air, which alternates between hot and cold with the heat released to achieve a cooling effect, thereby ensuring the stable operation of the brushless generator body 1.

[0044] Working principle: the brushless generator body 1 is working, the transmission impeller 13, the driving shaft 4 and the driving wheel 5 rotate synchronously to transmit and generate electricity, and at the same time, a pair of connecting plates 602 rotate synchronously with the driving shaft 4, and drive a pair of mounting plates 603 and a cleaning brush 604 to rotate along the outer wall of the breathable circular frame 2 to brush away the dust attached to its surface, and the brushless generator body 1 releases heat when working, the temperature rises, the carbon dioxide aqueous solution absorbs heat, and performs alternating hot and cold, and a pair of rotating convex rods 1001 also rotate synchronously with the pair of mounting plates 603, repeatedly contacting the movable rod 1003, and squeezing the movable rod 1003 to move toward the inside of the liquid storage frame 9 with the assistance of the second spring 1004, driving multiple stirring paddles 1006 to move repeatedly inside the liquid storage frame 9, and dialing The carbon dioxide aqueous solution is moved to dissipate the heat stored in the carbon dioxide aqueous solution, and the moist carbon dioxide overflows outward under the action of the toggle, and disperses and flows to the multiple telescopic airbag columns 1104. As the moist carbon dioxide is blown in, the multiple telescopic airbag columns 1104 drive the top plate 1106 to extend upward, expand the contact area with the hot air, and use the evaporation and heat absorption of water vapor contained in the moist carbon dioxide gas to achieve the effect of heat absorption and cooling, further increasing the temperature of the brushless generator body 1, and the top plate 1106 moves upward, pulling the lifting plate 1201 and the round rod 1202 to move upward, prompting the pressing plate 1205 to press the control switch 1206 upward, driving the flashing indicator light 1207 and the refrigerator 12010 to work synchronously, and the refrigeration The device 12010 releases cold air to lower the temperature, and the flashing indicator light 1207 uses the repeated on and off changes of the light to drive the deformation memory telescopic rod 1209 to repeatedly contract and extend, pulling the transparent piston plate 1208 to repeatedly squeeze the cold air downward to flow into the liquid storage frame 9, and perform cold and hot alternation with the heat inside, thereby lowering the temperature of the liquid storage frame 9. At the same time, part of the cold air flows into the multiple telescopic airbag columns 1104 along with the humid carbon dioxide, so that under the surrounding of the liquid storage frames 9 on both sides and the multiple telescopic airbag columns 1104 on the top, multiple areas around the brushless generator body 1 are wrapped with cold air, and perform cold and hot alternation with the heat released by the brushless generator body 1, thereby achieving a cooling effect, thereby ensuring the stable operation of the brushless generator body 1. Then, when the brushless generator body 1 continues to work, After a period of time, the drive shaft 4 and the drive wheel 5 continue to rotate, causing the temperature between the drive shaft 4 and the bearing to rise, and the corresponding lubrication effect becomes worse. The timer 705 drives a pair of electric telescopic rods 706 and extrusion plates 707 to squeeze the lubricating oil inside the oil storage bag 701 downward according to the working time, and flows along the sealing plate 3 to the contact point between the drive shaft 4 and the bearing to replenish its lubrication and ensure its lubrication. The lubricating oil that does not stay at the contact point between the drive shaft 4 and the bearing and continues to flow downward is filtered by the filter screen 802 and enters the collection box 801. At the same time, a pair of straight cylinders 804 and T-shaped movable rods 805 rotate together with the mounting plate 603, driving the movable hemisphere 806 to repeatedly contact and separate with the fixed hemisphere 803, and is squeezed by it.With the assistance of the first spring 807 and the T-shaped movable rod 805, the movable hemisphere 806 separates and contacts the bottom of the collection box 801, generating vibrations, which causes the impurities blocked on the surface of the filter screen 802 to disperse under the vibration, and are not likely to gather together and cause clogging of the mesh.
