Technical Field

[0001] The present invention relates to the technical field of intake and exhaust of diesel generator sets, and specifically to an intake and exhaust device for a van-type low-noise diesel generator set. Background Art

[0002] A diesel generator set is a device that uses diesel as fuel to drive a generator to generate electric energy. The intake and exhaust device of a diesel generator set is an important part to ensure the normal operation of the diesel engine. The intake fan is the core component of the intake system of the diesel generator set. Its function is to compress air and send it into the combustion chamber of the diesel engine to provide sufficient air volume for the diesel engine.

[0003] Since diesel generates a certain amount of soot during combustion, if the exhaust pipe is not cleaned for a long time, it will lead to a decrease in the exhaust volume. At the same time, it is easy to cause damage to the internal components of the diesel generator. When the components are damaged, it will cause thick smoke in the discharged gas, which will then affect the external environment. Summary of the Invention

A connecting rod is installed on the cam through a bearing. The other end of the connecting rod is connected to the toggle rod through a bearing. The toggle rod is connected to the inner wall of the intake pipe through a bearing. A rubber rod is installed between the two toggle rods. The rubber rod is in contact with the filter screen. Static electricity can be generated by the friction between the rubber rod and the filter screen.

[0008] Further, the exhaust component includes an exhaust pipe. The exhaust pipe is connected to the exhaust end of the generator main body. An exhaust chamber is installed inside the exhaust pipe. An exhaust motor is arranged outside the exhaust chamber. Blades are installed inside the exhaust chamber. The blades are connected to the output end of the exhaust motor. The dust cleaning component is installed inside the exhaust pipe.

[0009] Further, the dust cleaning component includes a fixed rod and a collection bin. The collection bin is installed outside the exhaust pipe. The fixed rod is installed at the output end of the exhaust port. A dust cleaning spring and a dust cleaning filter plate are installed between the fixed rods. Multiple scraper plates are arranged inside the exhaust pipe. The bottom of the scraper plate is connected to the inner wall of the exhaust pipe through a bearing. The upper end of the scraper plate is connected to the inner wall of the exhaust pipe through multiple springs. An opening is provided at the position where the scraper plate is arranged on the exhaust pipe. The opening is connected to the collection bin. The collection bin can collect the dust on the dust cleaning filter plate.

[0010] Further, during dust cleaning: the power supply to the springs on the scraper plate needs to be disconnected, and power is supplied to the dust cleaning spring.

[0011] When the scraper plate contacts the dust cleaning filter plate: the scraper plate can scrape and collect the dust on the dust cleaning filter plate.

[0012] Further, an air inlet and multiple heat dissipation openings are provided on the box body. The cooling component is installed inside the box body. The cooling component is matched with the air inlet. The cooling component includes a cooling fan and two semiconductor refrigeration sheets. The cooling fan is installed between the two semiconductor refrigeration sheets.

[0018] 2. When the intake assembly is in use, it can increase the gas entering the generator main body, thereby achieving a more efficient air supply effect. At the same time, when the intake assembly increases the intake air, it can filter the outside air twice. The gas will first pass through the filter assembly to achieve the first filtration, and then pass through the intake wheel. Since the intake wheel is provided with a filter net, when the intake wheel rotates to drive the wind, the filter net can also filter some dust so that the gas entering the cylinder is relatively clean;

[0019] 3. When the exhaust assembly is in use, since this generator is a diesel generator, the discharged gas will carry a large amount of thick smoke. When the exhaust assembly discharges the flue gas, it can filter the particulate matter in the flue gas and reduce the concentration of the flue gas. Because the exhaust assembly filters the particulate matter in the flue gas, the particles in the flue gas of an ordinary exhaust pipe will adsorb on the inner wall of the pipe. Over time, this will affect the smoke exhaust efficiency. Although the exhaust assembly will also have particles adsorbed on the inner wall of the pipe, when the ash cleaning assembly works, the particles attached to the ash cleaning filter plate will be scraped off by the scraper, and the particles on the inner wall of the pipe will fall during the oscillation of the ash cleaning filter plate. Therefore, when the exhaust chamber is cleaned later, the soot particles can be cleaned together. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] 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.

[0029] Embodiment: As Figures 1 - 7 shown, the present invention provides a technical solution for an intake and exhaust device of a van-type low-noise diesel generator set, including a generator main body 1, an intake assembly 2, an exhaust assembly 3, and a controller. The generator main body 1 includes a box body 11, and a cooling assembly 4 and a noise reduction assembly 5 are installed inside the box body 11. The intake assembly 2 and the exhaust assembly 3 are respectively connected to the generator main body 1. A filter assembly 6 is installed inside the intake assembly 2, and an ash cleaning assembly 7 is installed inside the exhaust assembly 3. The cooling assembly 4 can reduce the heat of the generator main body 1, the noise reduction assembly 5 can reduce the noise of the generator main body 1, and the ash cleaning assembly 7 can assist in cleaning the dust inside the exhaust assembly 3;

[0030] When the generator main body 1 is in use, through its air intake assembly 2 and exhaust assembly 3, the working efficiency and service life of the generator main body 1 can be effectively improved. At the same time, when the generator main body 1 is in use, the generated noise can also be reduced by the noise reduction assembly 5. And because the generator main body 1 generates a certain amount of high temperature inside during long-term operation, through the internal cooling assembly 4, it can cool the generator main body 1 on the premise of noise reduction. Specifically in use, when the generator main body 1 is started, the air intake assembly 2 and the exhaust assembly 3 will work simultaneously. At the same time, the temperature of the generator main body 1 will gradually rise, so it is necessary to start the cooling assembly 4 to control the temperature of the generator main body 1 and prevent the temperature of the generator main body 1 from being too high. When the air intake assembly 2 is in use, through the internal air intake motor 23 and the air intake wheel 24, it can accelerate the air intake efficiency and also play a certain cooling effect. At the same time, the filter assembly 6 above the air intake pipe 21 can filter the incoming gas and reduce the particulate matter entering the device. When the generator main body 1 exhausts, because this generator is a diesel generator, the exhausted gas will carry a large amount of thick smoke. When the exhaust assembly 3 discharges the flue gas, it can filter the particulate matter in the flue gas and reduce the concentration of the flue gas. Because the exhaust assembly 3 filters the particulate matter in the flue gas, the particles in the flue gas of an ordinary exhaust pipe will be adsorbed on the inner wall of the pipe, which will affect the exhaust efficiency over time. Although the exhaust assembly 3 will also have particles adsorbed on the inner wall of the pipe, when the ash cleaning assembly 7 works, the particles attached to the cleaning filter plate will be scraped off by the scraper 75, and the particles on the inner wall of the pipe will fall during the vibration of the ash cleaning filter plate 74. Then, when cleaning the exhaust chamber 32 later, the soot particles can be cleaned together. Therefore, when the device is in use, it can effectively maintain the working efficiency and service life of the generator main body 1.

[0031] As Figures 3 - 4 shown, in this embodiment, specifically, the air intake assembly 2 includes an air intake pipe 21. A drive chamber 22 is installed at the bottom of the air intake pipe 21. An air intake motor 23 is arranged outside the drive chamber 22. An air intake wheel 24 is installed inside the drive chamber 22. The air intake wheel 24 is connected to the output end of the air intake motor 23. Multiple groups of mounting frames are arranged on the air intake wheel 24, and a filter net is arranged between the mounting frames. A filter assembly 6 is installed inside the air intake pipe 21;

[0032] When the air intake assembly 2 is in use, it can increase the gas entering the generator main body 1, and then achieve a more efficient air supply effect. At the same time, while increasing the air intake, the air intake assembly 2 can filter the outside air twice. The gas will first pass through the filter assembly 6 to achieve the first filtration, and then pass through the air intake wheel 24. Because there is a filter net on the air intake wheel 24, while rotating to drive the air, the filter net can also filter some dust so that the gas entering the cylinder is relatively clean.

[0033] As Figure 4 shown, in this embodiment, specifically, the filtering component 6 includes a filter screen 61, two groups of mounting plates 62 and two groups of lever rods 63. The filter screen 61 is installed in the air inlet pipe 21. The two groups of mounting plates 62 are installed outside the air inlet pipe 21. A double-rotor motor 64 is installed between the two groups of mounting plates 62. Both ends of the double-rotor motor 64 are connected to the mounting plates 62 through bearings. Cams 65 are respectively installed at both ends of the double-rotor motor 64. A connecting rod is installed on the cam 65 through a bearing. The other end of the connecting rod is connected to the lever rod 63 through a bearing. The lever rod 63 is connected to the inner wall of the air inlet pipe 21 through a bearing. A rubber rod 66 is installed between the two groups of lever rods 63. The rubber rod 66 is in contact with the filter screen 61. Friction between the rubber rod 66 and the filter screen 61 can generate static electricity;

[0034] When the filtering component 6 is in use, it can attract the dust entering the air inlet pipe 21, thereby achieving the filtering effect. Specifically, when in use, the double-rotor motor 64 drives the cams 65 at both ends to rotate. When the cam 65 rotates, it will drive the connecting rod connected to the cam 65 to rotate together. The other end of the connecting rod is connected to the lever rod 63, so the lever rod 63 will be driven to swing. Since the lever rod 63 is connected to the inner wall of the air inlet pipe 21 through a bearing, the lever rod 63 will swing with the connection point as the midpoint. Also, since a rubber rod 66 is installed between the two groups of lever rods 63, when the rubber rod 66 rubs against the filter screen 61, static electricity will be generated. Since the material of the filter screen 61 of this device is polyester fiber, it can generate static electricity more easily. After the filter screen 61 generates static electricity, for the passing air, the dust in it will be adsorbed on the filter screen 61, thereby achieving the filtering effect.

[0035] As Figures 5 - 6 shown, in this embodiment, specifically, the exhaust component 3 includes an exhaust pipe 31. The exhaust pipe 31 is connected to the exhaust end of the generator main body 1. An exhaust chamber 32 is installed inside the exhaust pipe 31. An exhaust motor 33 is arranged outside the exhaust chamber 32. A blade 34 is installed inside the exhaust chamber 32. The blade 34 is connected to the output end of the exhaust motor 33. A dust cleaning component 7 is installed inside the exhaust pipe 31;

[0036] When the exhaust component 3 of the device is in use, since the generator is a diesel generator, the discharged gas will carry a large amount of thick smoke. When the exhaust component 3 discharges the flue gas, it can filter the particulate matter in the flue gas and reduce the concentration of the flue gas. Because the exhaust component 3 filters the particulate matter in the flue gas, the particles in the flue gas of an ordinary exhaust pipe will be adsorbed on the inner wall of the pipe. Over time, this will affect the exhaust efficiency. Although some particles will also be adsorbed on the inner wall of the pipe of the exhaust component 3, when the ash cleaning component 7 works, the particles attached to the ash cleaning filter plate 74 will be scraped off by the scraper 75, and the particles on the inner wall of the pipe will fall during the oscillation of the ash cleaning filter plate 74. Then, when cleaning the exhaust chamber 32 later, the soot particles can be cleaned together.

[0037] As Figure 6 shown, in this embodiment, specifically, the ash cleaning component 7 includes a fixed rod 71 and a collection bin 72. The collection bin 72 is installed outside the exhaust pipe 31, the fixed rod 71 is installed at the output end of the exhaust port, an ash cleaning spring 73 and an ash cleaning filter plate 74 are installed between the fixed rods 71, multiple groups of scrapers 75 are arranged in the exhaust pipe 31, the bottom of the scraper 75 is connected to the inner wall of the exhaust pipe 31 through a bearing, the upper end of the scraper 75 is connected to the inner wall of the exhaust pipe 31 through multiple groups of springs, an opening is provided at the connection part of the exhaust pipe 31 where the scraper 75 is arranged, and the opening is connected to the collection bin 72. The collection bin 72 can collect the dust on the ash cleaning filter plate 74;

[0038] When the ash cleaning component 7 is in use, it can filter the discharged flue gas and reduce the pollution to the outside. At the same time, the particles attached to the inner wall of the exhaust pipe 31 and the ash cleaning filter plate 74 can also be collected under the action of the ash cleaning component 7. Specifically, when in use, the flue gas passes through the exhaust pipe 31 and the ash cleaning filter plate 74 at the same time, and then the particulate matter in the flue gas is filtered by the ash cleaning filter plate 74. After that, when it is necessary to clean the dust, only need to disconnect the power supply to the spring on the scraper 75 through the controller to make the scraper 75 fall naturally, and then supply power to the ash cleaning spring 73 through the controller. When the ash cleaning spring 73 slowly drives the ash cleaning filter plate 74 to move downward, when it reaches the lowest point, the power supply to the ash cleaning spring 73 will be disconnected, so that the ash cleaning spring 73 drives the ash cleaning filter plate 74 to shake, and the shaking of the ash cleaning filter plate 74 will also oscillate the exhaust pipe 31, so as to clean the exhaust pipe 31 and the ash cleaning filter plate 74 at the same time. Part of the dust on the ash cleaning filter plate 74 will enter the collection bin 72 along with the scraper 75, and then the dust is collected through the collection bin 72.

[0039] As Figure 6 shown, in this embodiment, specifically, when cleaning the ash: it is necessary to disconnect the power supply to the spring on the scraper 75 and supply power to the ash cleaning spring 73;

[0040] When the scraping plate 75 contacts the dust cleaning filter plate 74: the scraping plate 75 can scrape and collect the dust on the dust cleaning filter plate 74;

[0041] When the flue gas passes through the exhaust pipe 31, it will also pass through the dust cleaning filter plate 74. Then, the particulate matter in the flue gas is filtered through the dust cleaning filter plate 74. When it is necessary to clean the dust, only need to control the controller to cut off the power supply to the spring on the scraping plate 75, so that the scraping plate 75 can fall naturally. Then, the controller supplies power to the dust cleaning spring 73. When the dust cleaning spring 73 slowly drives the dust cleaning filter plate 74 to move downward, so that the scraping plate 75 can contact the dust cleaning filter plate 74, clean and collect the dust on the dust cleaning filter plate 74.

[0042] Such as Figure 2 and Figure 7 As shown in the figure, in this embodiment, specifically, the box body 11 is provided with an air inlet and multiple groups of heat dissipation ports. A temperature reduction component 4 is installed inside the box body 11. The temperature reduction component 4 is matched with the air inlet. The temperature reduction component 4 includes a temperature reduction fan 41 and two groups of semiconductor refrigeration chips 42. A temperature reduction fan 41 is installed between the two groups of semiconductor refrigeration chips 42;

[0043] When the temperature reduction component 4 of the device is in use, it can cool the generator main body 1, so that the temperature of the generator main body 1 can always be maintained in the best state, preventing the generator main body 1 from overheating. Specifically, when in use, the semiconductor refrigeration chip 42 can generate cold air, and the temperature reduction fan will cool the generator main body 1, blowing the cold air generated by the semiconductor refrigeration chip 42 towards the generator main body 1, so as to achieve the cooling effect.

[0044] Such as Figure 7 As shown in the figure, in this embodiment, specifically, multiple groups of noise reduction components 5 are respectively matched with the air inlet and the heat dissipation ports. The noise reduction component 5 includes a fixed pipe 51. Multiple groups of sound absorption pipes 52 and multiple groups of sound absorption plates 53 are installed inside the fixed pipe 51. The multiple groups of sound absorption pipes 52 and sound absorption plates 53 are respectively installed equidistantly inside the fixed pipe 51;

[0045] When the noise reduction component 5 is in use, it can reduce the noise of the generator main body 1. And because the generator main body 1 is a van-type generator set, the noise of the van itself will be reduced to a certain extent. Coupled with this noise reduction component 5, it can maintain the noise reduction effect during the heat dissipation process. Because the box body 11 is provided with an air inlet and heat dissipation ports, generally, noise will be conducted to the outside from the air inlet and heat dissipation ports along with the air. And because the noise reduction component 5 is provided on both the air inlet and the heat dissipation ports, it can reduce the noise of the device without affecting the heat dissipation. Specifically, when the noise enters the fixed pipe 51 along with the air, it will pass through multiple groups of sound absorption pipes 52 and sound absorption plates 53. Due to the structure of the sound absorption pipes 52 and sound absorption plates 53 themselves, the noise conducted in the air can be reduced.

[0046] As Figure 7 shown, in this embodiment, specifically, multiple groups of holes are respectively provided on the sound-absorbing pipe 52 and the sound-absorbing plate 53, and the holes are respectively arranged on the sound-absorbing pipe 52 and the sound-absorbing plate 53 at unequal intervals;

[0047] Because multiple groups of holes are provided on the sound-absorbing pipe 52 and the sound-absorbing plate 53, when noise passes through the holes along with the air, since the holes are respectively arranged on the sound-absorbing pipe 52 and the sound-absorbing plate 53 at unequal intervals, thus when passing through multiple holes, the noise conducted in the air will be gradually weakened, thereby achieving the effect of noise reduction.

[0048] As Figures 1 - 2 shown, in this embodiment, specifically, a controller is installed inside the box body 11, and a control panel is provided outside the box body 11, and the control panel is connected to the controller;

[0049] When the device is in use, the controller can control each device and accessory of the generator main body 1, and because the control panel is connected to the controller, further, the staff can indirectly control the generator main body 1 through the control panel.

[0050] Working principle: When the generator main body 1 is in use, through its air intake assembly 2 and exhaust assembly 3, the working efficiency and service life of the generator main body 1 can be effectively improved. At the same time, when the generator main body 1 is in use, the noise generated can also be reduced by the noise reduction assembly 5. And because the generator main body 1 generates a certain amount of high temperature inside during long-term operation, through the internal cooling assembly 4, the generator main body 1 can be cooled on the premise of noise reduction. Specifically, when the generator main body 1 is started, the air intake assembly 2 and the exhaust assembly 3 will work simultaneously. At the same time, the temperature of the generator main body 1 will gradually rise, so it is necessary to start the cooling assembly 4 to control the temperature of the generator main body 1 and prevent the temperature of the generator main body 1 from being too high. When the air intake assembly 2 is in use, the air intake motor 23 inside it cooperates with the air intake wheel 24 to improve the air intake efficiency and can also play a certain cooling effect. At the same time, the filter assembly 6 above the air intake pipe 21 can filter the incoming gas and reduce the entry of particulate matter into the device. When the generator main body 1 exhausts, because this generator is a diesel generator, the exhausted gas will carry a large amount of thick smoke. When the exhaust assembly 3 discharges the flue gas, it can filter the particulate matter in the flue gas and reduce the concentration of the flue gas. Because the exhaust assembly 3 filters the particulate matter in the flue gas, the particles in the flue gas of an ordinary exhaust pipe will adsorb on the inner wall of the pipe, which will affect the exhaust efficiency over time. Although the exhaust assembly 3 will also have particles adsorbed on the inner wall of the pipe, when the ash cleaning assembly 7 works, the particles attached to the cleaning filter plate will be scraped off by the scraper 75, and the particles on the inner wall of the pipe will fall during the oscillation of the ash cleaning filter plate 74. Then, when cleaning the exhaust chamber 32 subsequently, the soot particles can be cleaned together. Therefore, when this device is in use, it can effectively maintain the working efficiency and service life of the generator main body 1.
