Description

Technical Field

[0001] This utility model belongs to the technical field of engine air intake devices, specifically relating to an air intake booster device for marine engines. Background Technology

[0002] In the field of marine engineering, engine intake superchargers have always played a key role in improving engine performance and increasing ship power output. By using a turbocharger to compress air, the intake pressure of the engine is increased, thereby increasing the engine's combustion efficiency. When the supercharger is working, a filter structure is installed at the intake of the supercharger to prevent dust in the gas from entering the engine. The traditional method is to add an air filter and replace it regularly. However, this method not only requires manual maintenance but also increases the operating cost. In addition, there is a possibility that the air filter will be forgotten to be replaced, causing the device to become clogged, which will prevent the engine from intakeing properly and increase the chance of engine damage.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Please see Figures 1-10 As shown, this utility model provides the following technical solution:

[0030] A marine engine intake booster includes an air delivery component. The air delivery component has an internal delivery channel for delivering pressurized gas along a preset path. The delivery channel includes an intake end and an outlet end connected to the engine. A filter element for filtering the gas is installed inside the intake end. A drive element and a cleaning element for scraping the filter element are fixedly connected to the air delivery component. The cleaning element is connected to the drive element, and the drive element drives the cleaning element to rotate cyclically relative to the filter element to scrape the filter element.

[0031] Through the above technical solution, since ships may encounter various emergencies during navigation, such as engine failure and air intake system problems, the crew needs to have the ability to respond quickly and effectively to ensure the safety of the ship. Therefore, personnel need to undergo emergency training and practice connecting and disconnecting the engine and the air intake pressurization device. When personnel need to conduct emergency training, the air outlet of the air supply component is connected to the air intake of the engine, thus connecting the air supply component to the engine. When the engine is running, the air supply component works, thereby drawing in outside air. When the air supply component draws in outside air, it filters the air through a filter element to remove dust. After filtration, the air enters the interior of the air supply component, where it is pressurized and delivered to the engine for use. Furthermore, when the filter element filters the air, the drive component rotates relative to the cleaning component, thereby allowing the cleaning component to continuously clean the filter element, preventing dust from accumulating on the air intake side of the filter element. This allows the filter element to continuously filter the air, eliminating the need for personnel to manually replace the filter structure periodically.

[0032] Specifically, in one embodiment, regarding the aforementioned gas delivery component, such as Figures 1-5 As shown, the gas transmission component includes a pressurizing component 4 for pressurizing gas. The inlet end and outlet end of the pressurizing component 4 are respectively fixedly connected to an inlet pipe 6 and an outlet pipe 3. The driving component and the filter component are both installed on the inlet pipe 6.

[0033] In this embodiment, when personnel need to connect the device to the engine, the exhaust pipe 3 is connected to the engine's intake end. When the engine needs to draw in gas, the pressurizing component 4 works, thereby generating suction to draw gas from the intake pipe 6, causing the intake pipe 6 to draw in external gas, and then drawing external gas into the intake pipe 6. The gas entering the intake pipe 6 is filtered by the filter.

[0034] Furthermore, in this utility model, regarding the aforementioned filter element, as follows: Figures 4-5 As shown, the filter includes a filter screen 10, and at least two air inlet slots 11 are provided on the circumferential surface of the air inlet pipe 6. The filter screen 10 is fixedly connected to the inside of the air inlet slots 11.

[0035] In this embodiment, when the intake pipe 6 draws in gas, the intake groove 11 on the intake pipe 6 supports the filter screen 10. When the gas enters the interior of the intake pipe 6 through the filter screen 10, the gas is filtered by the filter screen 10, thereby removing dust from the gas.

[0036] Regarding how to clean the filter screen 10, for example... Figures 4-6 As shown, the cleaning component includes a rotating frame 12, on the side of the rotating frame 12 facing the air intake pipe 6, a brush 13 is attached.

[0037] In this embodiment, when the filter screen 10 needs to be cleaned, the driving component works, thereby causing the rotating frame 12 to rotate, which in turn causes the brush 13 to rotate, and the brush 13 to scrape the filter screen 10, thereby cleaning the filter screen 10 and enabling the filter screen 10 to continuously filter gas.

[0038] Specifically, in one embodiment, regarding the aforementioned driving component, such as Figures 4-6 As shown, the driving component includes a motor 9 coaxially arranged with the air intake pipe 6, a connecting shaft 8 connected to the output end of the motor 9, and a connecting frame 7 fixedly connected between the connecting shaft 8 and the rotating frame 12.

[0039] In this embodiment, when it is necessary to drive the rotating frame 12 to rotate, the motor 9 works, which in turn drives the connecting shaft 8 to rotate. The connecting shaft 8 drives the connecting frame 7 to rotate, which in turn drives the rotating frame 12 to rotate, which in turn drives the brush 13 to rotate, so that the brush 13 scrapes the filter screen 10.

[0040] Regarding how exhaust pipe 3 is connected to the engine, such as... Figures 1-2 and Figures 4-5 As shown, the end of the air outlet pipe 3 away from the pressurizing component 4 is fixedly connected to a connecting flange 2, and a sealing ring 1 is provided inside the connecting flange 2.

[0041] In this embodiment, when personnel need to connect the exhaust pipe 3 to the engine, the exhaust pipe 3 is connected to the engine through the connecting flange 2, thereby connecting the device to the engine. Furthermore, the airtightness of the connecting flange 2 after it is connected to the engine intake end is increased through the cooperation of the sealing ring 1.

[0042] Specifically, in one embodiment, regarding the aforementioned pressurizing member 4, as... Figures 1-3 As shown, the pressurizing component 4 includes a housing 42, and a pressurizing fan 41 is installed inside the housing 42.

[0043] In this embodiment, when the pressurizing component 4 needs to draw in gas, the housing 42 supports the pressurizing fan 41, and the pressurizing fan 41 works to draw in gas, so that the air inlet pipe 6 draws in external gas.

[0044] To prevent water from accidentally entering the air intake pipe 6, such as Figures 1-2 , Figures 7-10 As shown, a water baffle 5 for blocking the air intake slot 11 is fixedly connected to the top of the connecting shaft 8. The water baffle 5 includes a water baffle 51, and the horizontal height of the lowest point of the water baffle 51 is lower than the horizontal height of the lowest point of the air intake slot 11.

[0045] In this embodiment, when the air intake slot 11 on the air intake pipe 6 draws in gas, the water baffle 51 blocks the air intake slot 11. Since the lowest point of the water baffle 51 is lower than the lowest point of the air intake slot 11, the probability of external water entering the air intake pipe 6 through the air intake slot 11 is reduced, allowing the device to draw in gas normally and operate.

[0046] To further reduce the chance of water entering the air intake pipe 6, such as Figures 7-10 As shown, a conical member 52 is coaxially fixedly connected inside the water shield 51. The conical member 52 includes an inner cover 522, and the inner cover 522 has a through hole 523 for the air inlet pipe 6 to pass through. A gap for gas to pass through is formed between the through hole 523 and the air inlet pipe 6. The air inlet groove 11 is located between the bottom of the inner cover 522 and the top of the inner cover 51.

[0047] In this embodiment, when the water shield 51 blocks the air intake pipe 6, the inner cover 522 inside the air intake pipe 6 cooperates with the inner cover 522 to block the air intake slot 11. The through hole 523 allows the gas to be easily drawn into the air intake slot 11, and further reduces the probability of water entering the air intake slot 11.

[0048] Furthermore, if water accidentally enters the water-blocking cover 51, in order to improve the efficiency of water discharge from the water-blocking cover 51, an inclined guide channel 521 is formed inside the inner cover 522 from its top to its bottom.

[0049] In this embodiment, the water that accidentally enters between the water shield 51 and the inner cover 522 is discharged through the guide channel 521, reducing the probability of water entering the air intake slot 11.

[0050] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
