Description

Technical Field

[0001] The present invention relates to the technical field of carbon brushes, specifically a carbon brush dust collector for a generator set. Background Art

[0002] A carbon brush is a device for transmitting energy or signals between the fixed part and the rotating part of an electric motor or other rotating machinery. It is generally made of pure carbon plus a solidifying agent, and its appearance is generally square. It is stuck on a metal bracket, and there is a spring inside to tightly press it against the rotating shaft. When the motor rotates, electrical energy is transmitted to the coil through the commutator.

[0003] During the use of the carbon brush, it is continuously rubbed, which easily causes wear of the carbon brush. And carbon dust is generated during the rubbing process, which is easy to suspend in the air and is harmful to the staff. In addition, some carbon dust will generate oily impurities when it encounters lubricating oil. If not filtered, the oily impurities will fly into the air. In addition, generally, there are fewer air outlets in the carbon brush dust collector, and the air outlets are not aligned with the carbon brushes, which easily affects the dust removal effect. Therefore, a carbon brush dust collector for a generator set is needed to solve the existing deficiencies. Summary of the Invention

[0004] The purpose of the present invention is to make up for the deficiencies of the prior art and provide a carbon brush dust collector for a generator set.

[0005] To achieve the above purpose, the present invention provides the following technical solution: A carbon brush dust collector for a generator set, including a base, a filter box is fixedly connected to the top of the base, a filter plate is movably connected inside the filter box, and a limiting mechanism is arranged at the top of the filter plate. One side of the filter box is movably connected with a sewage guiding cylinder through a bearing, and the sewage guiding cylinder is conical. A rotating mechanism is arranged on the outer side of the sewage guiding cylinder. The other end of the sewage guiding cylinder is movably connected with a cleaning cylinder through a bearing. An annular groove is opened inside the cleaning cylinder. Several air inlet pipes are communicated with the outer side of the cleaning cylinder, and several air outlet pipes are communicated with the inner side of the cleaning cylinder. The pipe orifice ends of the air outlet pipes all bend towards the inside of the cleaning cylinder, and the air outlet pipes are distributed in a circular array. An air suction fan is fixedly connected to the other end of the filter box.

[0006] The above-mentioned limiting mechanism includes a pulling rope, a blocking block, a limiting rod and a limiting spring. Both ends of the pulling rope are fixedly connected with blocking blocks. The other ends of the blocking blocks are fixedly connected with limiting rods. The other ends of the blocking blocks are fixedly connected with limiting springs. The limiting springs are sleeved on the outer sides of the limiting rods.

[0007] At the top of the above-mentioned filter plate, a handle is fixedly connected. The handle is in a convex shape. The pulling rope is movably connected inside the handle. At both ends of the handle, moving grooves are provided. The stop block, the limiting rod and the limiting spring are all movably connected inside the moving groove. One end of the limiting spring away from the stop block is fixedly connected inside the moving groove. One end of the limiting rod away from the stop block passes through the moving groove and extends to the outside of the handle.

[0008] At the top of the above-mentioned filter box, a plurality of groups of symmetric limiting blocks are fixedly connected. Inside the limiting blocks, limiting holes are provided, and the limiting rods are adapted to the limiting holes.

[0009] At the middle bottom of the above-mentioned handle, a pressing block is movably connected. The pulling rope passes through the pressing block, and the pulling rope is fixedly connected to the pressing block.

[0010] At the above, the rotating mechanism includes an external gear ring, a connecting rod, a driving gear and a servo motor. The connecting rods are several and are distributed in a circular array. One end of each connecting rod is fixedly connected to the outside of the sewage guiding cylinder, and the other end of each connecting rod is fixedly connected to the inside of the external gear ring. The servo motor is fixedly connected to the inside of the base. The output end of the servo motor is fixedly connected with a driving gear, and the external gear ring meshes with the driving gear.

[0011] At the above, several scraping plates are fixedly connected to the inside of the cleaning cylinder. The scraping plates are distributed in a circular array. The other ends of the scraping plates all extend to the inside of the cleaning cylinder, and the other ends of the scraping plates all fit against the inside of the cleaning cylinder.

[0012] At the above, a sewage discharge pipe is communicated with the outside of the cleaning cylinder, and the sewage discharge pipe is located directly below the cleaning cylinder.

[0013] Compared with the prior art, the carbon brush dust collector of this generator set has the following beneficial effects:

[0014] First, through the set limiting mechanism of the present invention, when replacing the filter plate, the pressing block is squeezed upward, driving the middle section of the pulling rope to move upward, so that the two ends of the pulling rope move toward the inside of the handle, pulling the stop block into the inside of the moving groove, making the limiting spring longer, and driving the limiting rod to separate from the limiting hole. Then, pulling the handle upward can separate the filter plate from the filter box, thus facilitating the staff to quickly replace the filter plate and ensuring the filtering and cleaning effect of the filter box.

[0015] Second, through the set rotating mechanism of the present invention, when the servo motor is started, it drives the driving gear to rotate, thereby driving the external gear ring to rotate. Under the action of the connecting rod, the sewage guiding cylinder is driven to rotate synchronously, and then the scraping plates scrape the impurities adhered to the inner wall of the cleaning cylinder. Under the action of gravity, it is convenient for the impurities to slide to the bottom of the cleaning cylinder and be discharged from the sewage discharge pipe, which is beneficial to avoiding the accumulation of impurities around the carbon brush and causing motor failures.

[0016] III. In the present invention, through the arranged air outlet pipes, since the pipe orifice ends of the air outlet pipes are all bent towards the inside of the cleaning cylinder, the air coming out of the air outlet pipes can be aligned with the carbon brush heads, which can not only remove the debris generated during the operation of the carbon brushes, but also facilitate the cooling of the working carbon brushes. Moreover, the air outlet pipes are arranged in a circular array, which is beneficial to cleaning the debris from various angles.

[0017] Other advantages, objectives and features of the present invention will be described to some extent in the subsequent specification, and to some extent, will be obvious to those skilled in the art based on the study of the following text, or can be taught from the practice of the present invention.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0025] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0026] As Figures 1-6 shown, the present invention provides a technical solution: a carbon brush dust collector for a generator set, which includes a base 1. A filter box 2 is fixedly connected to the top end of the base 1. A filter plate 3 is movably connected inside the filter box 2. And a limiting mechanism 4 is arranged at the top end of the filter plate 3. One side of the filter box 2 is movably connected with a dirt guide cylinder 5 through a bearing. And the dirt guide cylinder 5 is conical. A rotating mechanism 6 is arranged on the outer side of the dirt guide cylinder 5. The other end of the dirt guide cylinder 5 is movably connected with a cleaning cylinder 7 through a bearing. An annular groove 8 is formed inside the cleaning cylinder 7. Several air inlet pipes 9 are communicated with the outer side of the cleaning cylinder 7. Several air outlet pipes 10 are communicated with the inner side of the cleaning cylinder 7. The pipe orifice ends of the air outlet pipes 10 all bend towards the inside of the cleaning cylinder 7. And the air outlet pipes 10 are distributed in a circular array. A suction fan 11 is fixedly connected to the other end of the filter box 2.

[0027] First, install the cleaning cylinder 7 outside the carbon brush, and adjust the cleaning cylinder 7 so that the air outlet of the air outlet pipe 10 is aligned with the carbon brush. Then connect the air inlet pipe 9 with the fan. The air generated by the fan enters the inside of the annular groove 8 and is discharged from the air outlet pipe 10. Thus, the debris and dust generated during the operation of the carbon brush are blown into the inside of the dirt guide cylinder 5 and enter the filter box 2 along the air guide cylinder. The debris entering the inside of the filter box 2 is filtered by the filter plate 3, so that the oil-containing impurities adhere to the filter plate 3. The filtered gas is then discharged after passing through the suction fan 11. In addition, by using the limiting mechanism 4, the filter plate 3 can be quickly replaced, thereby ensuring the filtering ability of the filter box 2.

[0028] As Figure 1 、 Figure 2 and Figure 4 shown, the limiting mechanism 4 includes a pull rope 401, a stop block 402, a limiting rod 403 and a limiting spring 404. Both ends of the pull rope 401 are fixedly connected with a stop block 402. The other end of the stop block 402 is fixedly connected with a limiting rod 403. The other end of the stop block 402 is fixedly connected with a limiting spring 404. The limiting spring 404 is sleeved on the outer side of the limiting rod 403. A handle 12 is fixedly connected to the top end of the filter plate 3. The handle 12 is in a convex shape. The pull rope 401 is movably connected inside the handle 12. Moving grooves 13 are formed at both ends of the handle 12. The stop block 402, the limiting rod 403 and the limiting spring 404 are all movably connected inside the moving grooves 13. The end of the limiting spring 404 away from the stop block 402 is fixedly connected to the inside of the moving grooves 13. The end of the limiting rod 403 away from the stop block 402 passes through the moving grooves 13 and extends to the outside of the handle 12. A plurality of groups of symmetric limiting blocks 14 are fixedly connected to the top end of the filter box 2. A limiting hole 15 is formed inside the limiting block 14. And the limiting rod 403 is adapted to the limiting hole 15. A pressing block 16 is movably connected to the bottom end of the middle section of the handle 12. The pull rope 401 passes through the pressing block 16. And the pull rope 401 is fixedly connected to the pressing block 16.

[0029] When replacing the filter plate 3, press the pressing block 16 upward, driving the middle section of the pulling rope 401 to move upward, so that both ends of the pulling rope 401 move toward the inside of the handle 12, pulling the stop block 402 into the inside of the moving groove 13, making the limiting spring 404 longer, thus driving the limiting rod 403 to separate from the limiting hole 15. Then, pull the handle 12 upward to separate the filter plate 3 from the filter box 2, which facilitates the staff to quickly replace the filter plate 3, thereby ensuring the filtering and cleaning effect of the filter box 2.

[0030] As Figure 1 、 Figure 3 、 Figure 5 and Figure 6 shown, the rotating mechanism 6 includes an external gear ring 601, a connecting rod 602, a driving gear 603 and a servo motor 604. The number of connecting rods 602 is several and they are distributed in a circular array. One end of each connecting rod 602 is fixedly connected to the outer side of the sewage guiding cylinder 5, and the other end of each connecting rod 602 is fixedly connected to the inner side of the external gear ring 601. The servo motor 604 is fixedly connected to the inner side of the base 1, the output end of the servo motor 604 is fixedly connected with the driving gear 603, and the external gear ring 601 meshes with the driving gear 603. The inner side of the cleaning cylinder 7 is fixedly connected with several scraping plates 17, which are distributed in a circular array. The other ends of the scraping plates 17 extend to the inner side of the cleaning cylinder 7, and the other ends of the scraping plates 17 are in contact with the inner side of the cleaning cylinder 7. A sewage discharge pipe 18 is communicated with the outer side of the cleaning cylinder 7, and the sewage discharge pipe 18 is located directly below the cleaning cylinder 7.

[0031] Start the servo motor 604 to drive the driving gear 603 to rotate, thereby driving the external gear ring 601 to rotate. Under the action of the connecting rod 602, drive the sewage guiding cylinder 5 to rotate synchronously, so that the scraping plates 17 scrape the impurities adhered to the inner wall of the cleaning cylinder 7. Under the action of gravity, it is convenient for the impurities to slide to the bottom of the cleaning cylinder 7 and be discharged from the sewage discharge pipe 18, which helps to avoid the accumulation of impurities around the carbon brush and cause motor failure.

[0032] Working principle: When in use, first install the cleaning cylinder 7 outside the carbon brush, and adjust the cleaning cylinder 7 so that the air outlet of the air outlet pipe 10 is aligned with the carbon brush. Then connect the air inlet pipe 9 to the fan. The air generated by the fan enters the inside of the annular groove 8 and is discharged from the air outlet pipe 10, so as to blow the debris and dust generated during the operation of the carbon brush into the inside of the dirt guide cylinder 5 and enter the inside of the filter box 2 along the air guide cylinder. The debris entering the inside of the filter box 2 is filtered by the filter plate 3, so that the oil-containing impurities adhere to the filter plate 3. The filtered gas is discharged after passing through the suction fan 11. Start the servo motor 604 to drive the driving gear 603 to rotate, thereby driving the outer gear ring 601 to rotate. Under the action of the connecting rod 602, drive the dirt guide cylinder 5 to rotate synchronously, and then the scraper 17 scrapes the impurities adhered to the inner side wall of the cleaning cylinder 7. Under the action of gravity, the impurities slide to the bottom end of the cleaning cylinder 7 and are discharged from the sewage discharge pipe 18. In addition, when replacing the filter plate 3, squeeze the pressing block 16 upward to drive the middle section of the pull rope 401 to move upward, so that the two ends of the pull rope 401 move into the inside of the handle 12, so as to pull the stopper 402 into the inside of the moving groove 13, make the limit spring 404 longer, and thus drive the limit rod 403 to separate from the limit hole 15. Then pull the handle 12 upward again to separate the filter plate 3 from the filter box 2.
