Description

Technical Field

[0001] This utility model relates to the field of power generation equipment technology, and in particular to a dustproof component and a generator having the dustproof component. Background Technology

[0002] A box-type generator is based on an existing open generator, with an additional generator housing added to enclose the generator. This provides excellent noise insulation, waterproofing, dustproofing, and protection against external interference. It has advantages such as strong protection, high integration, and high portability.

[0003] To ensure sound insulation and protection while maintaining adequate airflow for heat dissipation, box-type generators often have airflow inlets and outlets. To provide good protection, filters or filter cloths are installed at these inlets and outlets. However, after a period of use, dust often accumulates on the filters or filter cloths at the airflow inlets. This dust buildup clogs the mesh, hindering airflow and impeding its flow. Utility Model Content

[0004] To address the above shortcomings, this utility model provides a dustproof component and a generator with the dustproof component, which can solve the problem that dust accumulation at the airflow inlet of existing box-type generators affects airflow.

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

[0006] A dustproof component includes:

[0007] A substrate having an air inlet for allowing airflow to enter;

[0008] There are two rollers, which are respectively located on two opposite sides of the airflow inlet;

[0009] An active roller is rotatably mounted on the substrate.

[0010] A filter cloth is wound around the roller and the drive roller, and the filter cloth passes through the airflow inlet to cover the airflow inlet;

[0011] A drive mechanism, mounted on the substrate, is used to drive the active roller to rotate, thereby driving the filter cloth.

[0012] A brush is located on one side of the airflow inlet with its bristles in contact with the filter gauze. The brush is positioned at the side of the filter gauze that is away from the airflow inlet when the filter gauze is in motion.

[0013] Furthermore, the substrate is provided with an air inlet, the substrate has an opening at the position corresponding to the inlet of the air inlet, and the top surface of the air inlet has a notch to form the airflow inlet.

[0014] Furthermore, the top surface of the air intake hopper is inclined, and a guide surface is provided below the top surface of the air intake hopper. The guide surface extends to the opening of the substrate, and the guide surface is inclined in a direction that gradually decreases towards the opening.

[0015] Furthermore, a first pulley is coaxially arranged on the drive roller, and a second pulley is coaxially arranged on the brush. A transmission belt is wound around the first pulley and the second pulley, and the brush is rotatably mounted on the substrate.

[0016] Furthermore, the drive mechanism includes a motor, a first bevel gear mounted on the output shaft of the motor, and a second bevel gear mounted at the end of the drive roller. The motor is fixedly mounted on the base plate, and the first bevel gear and the second bevel gear mesh with each other.

[0017] Furthermore, a scraper is provided at the side position of the airflow inlet when the filter cloth is driven away, and the scraper abuts against the lower side of the portion of the filter cloth before it leaves the airflow inlet.

[0018] Furthermore, a scraper is provided at the side position of the airflow inlet when the filter cloth is driven in, and the scraper abuts against the lower side of the portion of the filter cloth before it enters the airflow inlet.

[0019] Furthermore, the substrate is provided with a dust collection bag at a position directly below the scraper.

[0020] Furthermore, the opening is provided with a perforated mesh panel for ventilation.

[0021] This utility model also provides a generator, including a generator housing, on which at least one dustproof component as described in any of the above claims is provided.

[0022] Compared with the prior art, the beneficial effects of this utility model are:

[0023] The dustproof component of this invention drives the filter gauze to pass through the brush at the airflow inlet. After the filter gauze comes into contact with the brush bristles, the dust is brushed off and leaves the airflow inlet. At this point, the filter gauze leaving the airflow inlet is relatively clean and can be used subsequently. Meanwhile, the relatively clean filter gauze that was originally inside the generator housing is conveyed into the airflow inlet. The relatively clean filter gauze will not clog the mesh and affect the airflow, thus ensuring the normal entry of airflow and the normal operation of the generator.

[0024] The generator of this utility model, by setting up a dustproof component, can avoid the situation where the mesh is blocked and affects the airflow, thus ensuring the normal entry of airflow and the normal operation of the generator. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances. Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0040] On the one hand, please refer to Figures 1 to 8 A preferred embodiment of the present invention provides a dustproof component, which mainly includes a substrate 10, a roller 20, an active roller 21, a filter cloth 30, a brush 40, and a driving mechanism.

[0041] The substrate 10 has a flat plate structure and is detachably mounted on the side of the generator housing. An air inlet 11 is provided on the substrate 10 for airflow to enter.

[0042] There are two rollers 20, which are respectively set on two opposite sides of the airflow inlet 11. The rollers 20 can rotate around their own axis.

[0043] The active roller 21 is rotatably mounted on the base plate 10. Both ends of the active roller 21 are mounted through bearing seats so that it can rotate around its own axis.

[0044] The filter gauze 30 is wound around the roller 20 and the drive roller 21, and the filter gauze 30 passes through the airflow inlet 11 to cover the airflow inlet 11. The filter gauze 30 can achieve the function of filtration and protection. When the airflow enters through the airflow inlet 11, it passes through the filter gauze 30. Under the action of the filter gauze 30, the filter gauze 30 can block some dust and other impurities, so as to play a role in dust prevention.

[0045] The drive mechanism is mounted on the base plate 10 to drive the active roller 21 to rotate and drive the filter cloth 30 to drive the transmission. That is, the filter cloth 30 wound on the roller 20 and the active roller 21 can achieve transmission when the active roller 21 rotates. The part of the filter cloth 30 corresponding to the position of the airflow inlet 11 is not fixed, but circulates.

[0046] The brush 40 is located on one side of the airflow inlet 11, with its bristles in contact with the filter gauze 30. The brush 40 is positioned at the side of the filter gauze 30 when it moves away from the airflow inlet 11. The bristles of the brush 40 are soft to minimize damage to the filter gauze 30, and the bristles of the brush 40 cover the entire width of the filter gauze 30.

[0047] Understandably, during use, the roller 20, drive roller 21, filter cloth 30, and drive mechanism are located inside the generator housing, while the brush 40 is located outside the generator housing.

[0048] During implementation, the drive mechanism drives the active roller 21 to rotate, thereby driving the filter cloth 30. The filter cloth 30 slowly passes through the airflow inlet 11 and the brush 40 at the airflow inlet 11. At this time, some dust will accumulate on the filter cloth 30 originally located at the airflow inlet 11. After the filter cloth 30 is driven and comes into contact with the bristles of the brush 40, the dust is brushed off by the bristles and leaves the airflow inlet 11. The filter cloth 30 leaving the airflow inlet 11 is relatively clean and can be used later. The relatively clean filter cloth 30 originally inside the generator housing is conveyed into the airflow inlet 11. The relatively clean filter cloth 30 will not block the mesh and affect the airflow, thus ensuring the normal entry of airflow and the normal operation of the generator.

[0049] The drive mechanism drives the active roller 21 to rotate, thereby driving the filter cloth 30. This can be done continuously or intermittently, that is, it can be driven for a certain distance and then stop, and then drive again after a certain period of time. When the intermittent driving method is used, the driving distance is slightly greater than the length of the filter cloth 30 at the airflow inlet 11, so that a clean section of filter cloth 30 can be renewed and enter the airflow inlet 11 during each drive.

[0050] Preferably, the drive mechanism includes a motor 71, a first bevel gear 72 mounted on the output shaft of the motor 71, and a second bevel gear 73 mounted at the end of the drive roller 21. The motor 71 is fixedly mounted on the base plate 10, and the first bevel gear 72 and the second bevel gear 73 mesh with each other. A rotating shaft is provided at each end of the drive roller 21, and the rotating shaft is mounted on the base plate 10 via bearing seats. The second bevel gear 73 is fixedly mounted on the rotating shaft at one end of the drive roller 21. In operation, the motor 71 starts, driving the first bevel gear 72 to rotate, and the second bevel gear 73 rotates accordingly, thereby driving the drive roller 21 to rotate. The surface of the drive roller 21 has anti-slip textures for interacting with the filter gauze 30. The motor 71 is preferably a servo motor equipped with a timer to achieve intermittent start-up.

[0051] An air inlet hopper 50 is provided on the base plate 10, and the air inlet hopper 50 is disposed inward. The base plate 10 has an opening 12 at the position corresponding to the entrance of the air inlet hopper 50, and the top surface of the air inlet hopper 50 has a notch to form an airflow inlet 11. When the air inlet hopper 50 is provided, the two ends of the two rollers 20 are rotatably disposed on the two side walls of the air inlet hopper 50. When the air inlet hopper 50 is provided, the external airflow first enters the air inlet hopper 50 through the opening 12, and then enters the interior of the generator housing through the airflow inlet 11 formed by the notch on the top surface of the air inlet hopper 50.

[0052] The top surface of the air intake hopper 50 is sloped, and a guide surface 51 is provided below the top surface of the air intake hopper 50. The guide surface 51 extends to the opening 12 of the substrate 10. The guide surface 51 is inclined, and the inclination direction gradually decreases towards the opening 12. The combination of the sloped top surface of the air intake hopper 50 and the inclined guide surface 51 allows for a larger area of ​​the top surface of the air intake hopper 50, thereby enabling a larger opening and facilitating the formation of a larger airflow inlet 11 to facilitate airflow entry. The inclined guide surface 51 helps to guide and remove dust or other debris, such as leaves, that falls naturally from the filter gauze 30 at the airflow inlet 11 or is brushed off by the brush 40.

[0053] Preferably, a first pulley 61 is coaxially arranged on the drive roller 21, and a second pulley 62 is coaxially arranged on the brush 40. A transmission belt 63 is wound around the first pulley 61 and the second pulley 62. The brush 40 is rotatably mounted on the base plate 10. When the air inlet 50 is provided, the two ends of the brush 40 are rotatably mounted on the two side walls of the air inlet 50. When the drive roller 21 rotates, it can drive the first pulley 61, which in turn drives the second pulley 62 through the transmission belt 63, thereby driving the brush 40 to rotate, which helps to more efficiently brush off the dust on the filter gauze 30.

[0054] A scraper 31 is provided at the side position of the airflow inlet 11 when the filter gauze 30 is driven away. The scraper 31 abuts against the lower side of the part of the filter gauze 30 before it leaves the airflow inlet 11. The scraper 31 has a flexible edge that contacts the filter gauze 30. When the filter gauze 30 is driven away from the airflow inlet 11, it scrapes off the dust on the filter gauze 30 and falls down onto the inclined guide surface 51.

[0055] A scraper 31 is provided on the side of the airflow inlet 11 when the filter cloth 30 is driven in. The scraper 31 abuts against the lower side of the portion of the filter cloth 30 before it enters the airflow inlet 11. The scraper 31 has a flexible edge that contacts the filter cloth 30. Before the filter cloth 30 is driven into the airflow inlet 11, the scraper 31 scrapes off the dust on the filter cloth 30, ensuring that the filter cloth 30 entering the airflow inlet 11 is relatively clean. When an air intake hopper 50 is provided, the scraper 31 is installed on the air intake hopper 50. A dust collection bag 80 is provided on the base plate 10 at a position directly below the scraper 31. The dust falling down is collected by the dust collection bag 80 to keep the inside of the generator housing clean. The dust collection bag 80 is detachably installed on the base plate 10, preferably by a plug-in installation. For example, if a slot is provided on the air intake hopper 50, the dust collection bag 80 is inserted into the slot.

[0056] In one embodiment, a perforated mesh plate 13 is provided at the opening 12 of the substrate 10. By providing the perforated mesh plate 13, a good windbreak and dust suppression effect can be achieved, and it can also effectively prevent debris and small animals from entering, thus providing excellent protection. Figure 8 As shown, this is a horizontally arranged elongated hole structure, such as... Figure 7 As shown, it is a uniformly distributed through-hole structure. It can be understood that different forms of ventilation perforated mesh 13 can be selected according to specific needs.

[0057] On the other hand, this utility model provides a generator, please refer to... Figure 9 and Figure 10 The generator includes a generator housing 90, on which multiple dustproof components 100 are installed. The dustproof components 100 can be installed individually, side-by-side, or vertically, such as... Figure 10 As shown, two dustproof components 100 are installed vertically. By installing the dustproof components 100, it is possible to prevent the mesh from being blocked and affecting the airflow, thus ensuring the normal entry of airflow and the normal operation of the generator.

[0058] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
