[0001] This utility model belongs to the technical field of diesel generator sets, and in particular relates to a diesel generator set air intake and exhaust device. Background Technology

[0002] In a generator set, the diesel engine's volume decreases while its temperature rises rapidly, reaching the ignition point of diesel fuel. The diesel fuel ignites, the air-fuel mixture burns violently, and the volume expands rapidly, pushing the piston downwards, which is called work.

[0003] In existing diesel generator set air intake and exhaust devices, the filter plates at the air intake tend to accumulate a lot of dust and debris, which affects exhaust efficiency over time. While cleaning the dust on the outside of the filter plates is relatively easy, cleaning the inside of the filter plates is more troublesome and requires disassembly. To solve the above problems, it is necessary to provide a diesel generator set air intake and exhaust device. Utility Model Content

[0004] This utility model provides a diesel generator set air intake and exhaust device, which aims to solve the problem that in the use of existing diesel generator set air intake and exhaust devices, the filter plate at the air intake is prone to accumulating a lot of dust and debris, which affects the exhaust efficiency in the long run. It is relatively easy to clean the dust on the outside of the filter plate, but cleaning the inside of the filter plate is more troublesome and requires disassembly.

[0005] This utility model is implemented as follows: a diesel generator set air intake and exhaust device includes a rear mounting cylinder: the air intake end of the rear mounting cylinder is fixedly connected to a front air duct, the inner wall of the front air duct is provided with a fan slot, the inner wall of the fan slot is fixedly connected to a fan, the air intake end of the front air duct is fixedly connected to a front filter plate, and the inner wall of the front air duct is fixedly connected to an inner cleaning component.

[0006] The rear mounting cylinder has an inner baffle assembly on its inner wall and an auxiliary exhaust assembly on its inner wall. The auxiliary exhaust assembly is located on the side of the rear mounting cylinder closer to the front air duct, and the inner baffle assembly is located on the side of the rear mounting cylinder away from the front air duct.

[0007] Preferably, the internal cleaning assembly includes a mounting shell fixedly disposed on the inner wall of the front air duct, a pressing member is provided on the inner wall of the mounting shell, a pull rod is fixedly connected to the outer wall of the pressing member, and a cleaning brush is fixedly connected to one end of the pressing member.

[0008] Preferably, the pressing component includes an upper sliding cylinder, the outer wall of which is fixedly connected to a slider, and the inner wall of which is fixedly connected to an inner spring.

[0009] Preferably, the pressing component further includes a lower sliding cylinder disposed on the outer wall of the upper sliding cylinder, the outer wall of the lower sliding cylinder having an N-shaped groove, and the slider being movably disposed on the inner wall of the N-shaped groove.

[0010] Preferably, a slider is fixedly connected to one side of the upper sliding cylinder, the outer wall of the slider is slidably connected to the inner wall of the mounting shell, and the outer wall of the upper sliding cylinder is fixedly connected to the bottom of the pull rod;

[0011] The bottom of one end of the sliding cylinder is fixedly connected to one end of the cleaning brush.

[0012] Preferably, the auxiliary exhaust assembly includes a first telescopic hydraulic cylinder fixedly disposed on the outer wall of the rear mounting cylinder, the telescopic end of the first telescopic hydraulic cylinder being fixedly connected to a first connecting frame, the outer wall of the first connecting frame being fixedly connected to a blocking block, and the outer wall of the blocking block being slidably connected to the inner wall of the rear mounting cylinder.

[0013] Preferably, the inner baffle assembly includes a second telescopic hydraulic cylinder fixedly disposed on the outer wall of the rear mounting cylinder, and a blocking plate is fixedly connected to the telescopic end of the second telescopic hydraulic cylinder, wherein the outer wall of the blocking plate is slidably connected to the inner wall of the rear mounting cylinder.

[0014] Preferably, the exhaust end of the rear mounting cylinder is fixedly connected to a mounting plate, and the outer wall of the mounting plate is provided with several positioning holes.

[0015] Compared with the prior art, the embodiments of this application have the following main advantages:

[0016] The internal cleaning component, through its innovative structural design, significantly improves the ease of maintenance and cleaning efficiency of the diesel generator set's air intake and exhaust systems. This component mainly includes a mounting housing, a pressing element, a pull rod, and a cleaning brush. The pressing element consists of an upper sliding cylinder, a slider, an inner spring, a lower sliding cylinder, and an N-shaped groove. In practical applications, the user simply moves the pull rod to drive the upper sliding cylinder to slide along the inner wall of the mounting housing. The slider, in conjunction with the N-shaped groove, causes the lower sliding cylinder to rotate, thereby driving the cleaning brush to scrub the inside of the front filter plate. The inner spring ensures the component automatically resets after operation, supporting repeated cleaning actions. This design avoids the cumbersome steps of disassembling the filter plate required in traditional methods, reducing maintenance time and labor costs, while ensuring unobstructed air intake channels and effectively preventing a decrease in exhaust efficiency due to dust accumulation. Furthermore, the dust generated during the cleaning process can be promptly discharged by the fan, further improving the overall reliability and service life of the system, making it suitable for industrial environments requiring frequent maintenance.

[0017] The internal baffle assembly, through its adjustable sealing mechanism, enhances the safety and operational flexibility of the diesel generator set's air intake and exhaust system. This assembly consists of a second telescopic hydraulic cylinder and a blocking plate. The second telescopic hydraulic cylinder is fixed to the outer wall of the rear mounting cylinder and can drive the blocking plate to slide within the inner wall of the rear mounting cylinder. When cleaning the front filter plate, the internal baffle assembly activates, and the blocking plate moves inward, sealing the exhaust passage from the rear mounting cylinder to the diesel generator set. This action effectively isolates the generator set's interior, preventing dust or debris from entering critical components during cleaning, thus avoiding potential equipment damage or performance degradation. Simultaneously, this design allows for maintenance without shutting down the system. By switching air ducts, it ensures that the fan airflow is directed towards the auxiliary exhaust assembly, improving the reliability of continuous operation. The internal baffle assembly not only simplifies the maintenance process but also reduces operational risks, making it suitable for generator set applications with high stability and safety requirements, and extending the overall lifespan of the equipment.

[0018] The auxiliary exhaust assembly optimizes the cleaning process and system efficiency of the diesel generator set's air intake and exhaust system by providing a backup exhaust channel. This assembly includes a first telescopic hydraulic cylinder, a first connecting frame, and a plug. The first telescopic hydraulic cylinder is fixed to the outer wall of the rear mounting cylinder and controls the movement of the plug. During cleaning, the auxiliary exhaust assembly is activated, and the first telescopic hydraulic cylinder drives the plug to slide outward, opening the auxiliary exhaust channel of the rear mounting cylinder. This allows the airflow generated by the fan to be directly discharged through this channel, rather than entering the generator set, thus quickly carrying away dust dislodged during the cleaning of the pre-filter. This design not only improves cleaning effectiveness and reduces dust accumulation within the device but also avoids the risk of secondary pollution, ensuring the long-term efficient operation of the air intake and exhaust system. Furthermore, the auxiliary exhaust assembly works in conjunction with the internal cleaning assembly and the internal baffle assembly, achieving automation and seamless switching of the maintenance process, significantly improving operational convenience and system adaptability, making it suitable for generator set applications in high-dust environments.

It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0027] This utility model embodiment provides a diesel generator set air intake and exhaust device, including a rear mounting cylinder 7: the air intake end of the rear mounting cylinder 7 is fixedly connected to a front air duct 1, the inner wall of the front air duct 1 is provided with a fan slot 5, the inner wall of the fan slot 5 is fixedly connected to a fan, the air intake end of the front air duct 1 is fixedly connected to a front filter plate 6, and the inner wall of the front air duct 1 is fixedly connected to an inner cleaning component 2.

[0028] The inner wall of the rear mounting cylinder 7 is provided with an inner baffle assembly 4 and an auxiliary exhaust assembly 3. The auxiliary exhaust assembly 3 is located on the side of the rear mounting cylinder 7 closer to the front air duct 1, and the inner baffle assembly 4 is located on the side of the rear mounting cylinder 7 away from the front air duct 1.

[0029] The internal cleaning component 2 includes a mounting shell 201 fixedly installed on the inner wall of the front air duct 1. A pressing member 203 is provided on the inner wall of the mounting shell 201. A pull rod 204 is fixedly connected to the outer wall of the pressing member 203. A cleaning brush 202 is fixedly connected to one end of the pressing member 203.

[0030] The pressing component 203 includes an upper slide cylinder 2031, a slider 2032 fixedly connected to the outer wall of the upper slide cylinder 2031, and an inner spring 2033 fixedly connected to the inner wall of the upper slide cylinder 2031.

[0031] The pressing component 203 also includes a lower sliding cylinder 2034 disposed on the outer wall of the upper sliding cylinder 2031. The outer wall of the lower sliding cylinder 2034 is provided with an N-shaped groove 2035, and the slider 2032 is movably disposed on the inner wall of the N-shaped groove 2035.

[0032] A slider is fixedly connected to one side of the upper slide cylinder 2031. The outer wall of the slider is slidably connected to the inner wall of the mounting shell 201. The outer wall of the upper slide cylinder 2031 is fixedly connected to the bottom of the pull rod 204.

[0033] One end of the sliding cylinder 2034 is fixedly connected to one end of the cleaning brush 202.

[0034] The exhaust end of the rear mounting cylinder 7 is fixedly connected to the mounting plate 8, and the outer wall of the mounting plate 8 has several positioning holes.

[0035] It should be noted that, due to the existing diesel generator set's air intake and exhaust devices, the filter plates at the air intake tend to accumulate a lot of dust and debris during use, which affects exhaust efficiency over time. Cleaning the dust on the outside of the filter plates is relatively easy, but cleaning the inside of the filter plates is more troublesome and requires disassembly for cleaning.

[0036] Specifically, in this embodiment, the solution mainly utilizes the rear mounting cylinder 7, front air duct 1, fan trough 5, front filter plate 6, internal cleaning assembly 2, internal baffle assembly 4, and auxiliary exhaust assembly 3. In use, the mounting plate 8 is fixedly installed at the air inlet and outlet of the diesel generator set. Then, the exhaust is controlled via a separate unit. When cleaning the front filter plate 6 is required, the outer side of the front filter plate 6 is cleaned first. Then, the first telescopic hydraulic cylinder 303 is activated to move the blocking block 302 outward, opening the rear mounting cylinder 7 to create an auxiliary exhaust channel. Simultaneously, the second telescopic hydraulic cylinder 402 is activated to move the blocking plate 401 inward, opening the exhaust channel from the interior of the rear mounting cylinder 7 into the diesel generator set. The blockage allows the air intake of the fan to be discharged through the auxiliary exhaust channel. Then, the pull rod 204 is moved to one side, causing the upper slide cylinder 2031 to slide along the inner wall of the mounting shell 201. The upper slide cylinder 2031 moves closer to the lower slide cylinder 2034 and squeezes it, causing the slider 2032 on the upper slide cylinder 2031 to slide along the N-shaped groove 2035, thereby causing the lower slide cylinder 2034 to rotate. This drives the cleaning brush 202 on the lower slide cylinder 2034 to rotate, and the cleaning brush 202 cleans the inner and outer walls of the front filter plate 6. The pull rod 204 is released, and the upper slide cylinder 2031 returns to its original position under the action of the inner spring 2033. The operation is repeated to improve the cleaning effect. The dust that has been cleaned is discharged through the auxiliary exhaust channel by the fan.

[0037] In this embodiment, the internal cleaning component 2, through its innovative structural design, significantly improves the maintenance convenience and cleaning efficiency of the diesel generator set's air intake and exhaust system. This component mainly includes a mounting housing 201, a pressing element 203, a pull rod 204, and a cleaning brush 202. The pressing element 203 consists of an upper sliding cylinder 2031, a slider 2032, an inner spring 2033, a lower sliding cylinder 2034, and an N-shaped groove 2035. In practical applications, the user only needs to move the pull rod 204 to drive the upper sliding cylinder 2031 to slide along the inner wall of the mounting housing 201. The slider 2032, in conjunction with the N-shaped groove 2035, causes the lower sliding cylinder 2034 to rotate, thereby driving the cleaning brush 202 to scrub the inner side of the front filter plate 6. The inner spring 2033 ensures that the component automatically resets after operation, supporting repeated cleaning actions. This design avoids the cumbersome steps of disassembling filter plates required in traditional methods, reducing maintenance time and labor costs. It also ensures unobstructed air intake channels, effectively preventing a decrease in exhaust efficiency due to dust accumulation. Furthermore, dust generated during cleaning can be promptly expelled by the fan, further enhancing the overall reliability and lifespan of the system, making it suitable for industrial environments requiring frequent maintenance.

[0038] In a further preferred embodiment of the present invention, the inner baffle assembly 4 includes a second telescopic hydraulic cylinder 402 fixedly disposed on the outer wall of the rear mounting cylinder 7. The telescopic end of the second telescopic hydraulic cylinder 402 is fixedly connected to a blocking plate 401, and the outer wall of the blocking plate 401 is slidably connected to the inner wall of the rear mounting cylinder 7.

[0039] In this embodiment, the inner baffle assembly 4, through its adjustable sealing mechanism, enhances the safety and operational flexibility of the diesel generator set's air intake and exhaust system. This assembly consists of a second telescopic hydraulic cylinder 402 and a blocking plate 401. The second telescopic hydraulic cylinder 402 is fixed to the outer wall of the rear mounting cylinder 7 and can drive the blocking plate 401 to slide within the inner wall of the rear mounting cylinder 7. When cleaning the front filter plate 6, the inner baffle assembly 4 is activated, and the blocking plate 401 moves inward, blocking the exhaust passage from the rear mounting cylinder 7 to the diesel generator set. This action effectively isolates the generator set's interior, preventing dust or debris from entering critical components during cleaning, thereby avoiding potential equipment damage or performance degradation. Simultaneously, this design allows for maintenance without shutting down the system, ensuring airflow is directed to the auxiliary exhaust assembly 3 by switching the air duct, thus improving the reliability of continuous operation. The inner baffle assembly 4 not only simplifies the maintenance process but also reduces operational risks, making it suitable for generator set applications with high stability and safety requirements, and extending the overall lifespan of the equipment.

[0040] In a further preferred embodiment of the present invention, the auxiliary exhaust assembly 3 includes a first telescopic hydraulic cylinder 303 fixedly disposed on the outer wall of the rear mounting cylinder 7. The telescopic end of the first telescopic hydraulic cylinder 303 is fixedly connected to a first connecting frame 301. A block 302 is fixedly connected to the outer wall of the first connecting frame 301. The outer wall of the block 302 is in close contact with the inner wall of the rear mounting cylinder 7.

[0041] In this embodiment, the auxiliary exhaust assembly 3 optimizes the cleaning process and system efficiency of the diesel generator set's air intake and exhaust system by providing a backup exhaust channel. This assembly includes a first telescopic hydraulic cylinder 303, a first connecting frame 301, and a blocking block 302. The first telescopic hydraulic cylinder 303 is fixed to the outer wall of the rear mounting cylinder 7 and controls the movement of the blocking block 302. During cleaning, the auxiliary exhaust assembly 3 is activated, and the first telescopic hydraulic cylinder 303 drives the blocking block 302 to slide outward, opening the auxiliary exhaust channel of the rear mounting cylinder 7. This allows the airflow generated by the fan to be directly discharged through this channel, rather than entering the generator set, thereby quickly removing dust that falls off during the cleaning of the front filter plate 6. This design not only improves the cleaning effect and reduces dust accumulation within the device but also avoids the risk of secondary pollution, ensuring the long-term efficient operation of the air intake and exhaust system. Furthermore, the auxiliary exhaust assembly 3 works in conjunction with the internal cleaning assembly 2 and the internal baffle assembly 4, achieving automation and seamless switching of the maintenance process, significantly improving operational convenience and system adaptability, making it suitable for generator set applications in high-dust environments.
