Description

Technical Field

[0001] This utility model relates to the field of generator set technology, specifically to a generator set air guide mechanism. Background Technology

[0002] In common generator sets, the internal combustion engine needs to be guided by a shroud to direct the effective airflow from the turbine fan to cool the engine. Traditional shrouds have poor airflow guidance, and the motor that drives the turbine fan generates a lot of heat, which can easily be transferred to the generator. In addition, the direction of the cooling air is fixed, and it is easy to concentrate the airflow on one side of the cylinder block, resulting in poor heat dissipation performance and potentially causing insufficient performance of the internal combustion engine.

[0012] (III) Beneficial Effects

[0013] Compared with the prior art, this utility model provides a generator set air guide mechanism, which has the following features:

[0014] Beneficial effects:

[0015] 1. The air guide mechanism of this generator set uses a drive motor, driven wheel, rotating shaft, driving wheel and transmission belt in cooperation. When the turbine fan is running, the drive motor drives the driving wheel to rotate through the rotating shaft. The driving wheel drives the driven wheel to rotate through the transmission belt. The driven wheel drives the turbine fan to rotate through the rotating rod. As a result, the drive motor is located outside the air guide duct. The heat generated by the drive motor is not directly blown to the generator set, which further reduces the temperature of the air blown to the generator set by the device.

[0016] 2. The air guiding mechanism of this generator set uses a rotating pin, air guide plate, transmission plate, spring and adjusting bolt to work together. The adjusting bolt is pressed against the air guide plate at the top, the spring is pressed against the air guide plate at the bottom, and the transmission plate makes the three sets of air guide plates move together. When the insertion height of the adjusting bolt changes, the tilt angle of the air guide plate changes. This allows the operator to change the direction of the airflow guided by the air guide plate by adjusting the bolt. This makes it easier for the operator to guide the airflow to the main heat-generating parts of the generator set, further improving the air guiding effect of the air guiding mechanism.

[0021] 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.

[0022] Please see Figure 1-4This utility model provides a technical solution: a generator set air guide mechanism, including an air guide box 1 and an air guide pipe 2 connected to the right side of the air guide box 1. A protective cover 3 is connected to the front side of the outer surface of the air guide pipe 2. A support frame 4 is fixedly connected to the inner wall of the air guide pipe 2. A rotating rod 5 is rotatably connected to the inner wall of the support frame 4. A turbine fan 6 is fixedly connected to the right end of the rotating rod 5. A driven wheel 7 is fixedly fitted on the outer surface of the rotating rod 5. A rotating shaft 8 is rotatably connected to the inner wall of the protective cover 3. A driving wheel 9 is fixedly fitted on the outer surface of the rotating shaft 8. The driving wheel 9 and the driven wheel 7 are connected by a transmission belt 10. A drive motor 11 is fixedly connected to the right side of the cover 3. The output end of the drive motor 11 is fixedly connected to the right end of the rotating shaft 8. Three sets of rotating pins 12 are rotatably connected to the inner walls of the front and rear sides of the air guide box 1. A guide plate 13 is fixedly connected to the inner end of the rotating pin 12. A transmission plate 14 is rotatably connected to the right side of the front and back sides of the air guide plate 13. A spring 15 is fixedly connected between the bottom air guide plate 13 and the bottom inner wall of the air guide box 1. An adjusting bolt 16 is threadedly connected to the upper surface of the air guide box 1. Four sets of fixing plates 17 are fixedly connected to the left side of the outer surface of the air guide box 1. A mounting bolt 18 is inserted on the side. Through the cooperation of the drive motor 11, driven wheel 7, rotating shaft 8, driving wheel 9, and transmission belt 10, when the turbine fan 6 is running, the drive motor 11 drives the driving wheel 9 to rotate via the rotating shaft 8. The driving wheel 9 drives the driven wheel 7 to rotate via the transmission belt 10. The driven wheel 7 drives the turbine fan 6 to rotate via the rotating rod 5. This positions the drive motor 11 outside the air duct 2, preventing the heat generated by the drive motor 11 from being directly blown onto the generator set, further reducing the temperature of the air blown onto the generator set. This is achieved by rotating pin 1... 2. The air guide plate 13, transmission plate 14, spring 15 and adjusting bolt 16 work together so that the adjusting bolt 16 abuts against the air guide plate 13 at the top, the spring 15 abuts against the air guide plate 13 at the bottom, and the transmission plate 14 makes the three sets of air guide plates 13 move in tandem. When the insertion height of the adjusting bolt 16 changes, the tilt angle of the air guide plate 13 changes, so that the operator can change the direction of the airflow guided by the air guide plate 13 by adjusting the bolt 16, which makes it easier for the operator to guide the airflow to the main heat-generating part of the generator set, and further improves the air guiding effect of the air guiding mechanism.

[0023] In this invention, to further enhance the stability of the installation of the mounting bolt 18, a washer is fitted on the outer surface of the mounting bolt 18. The washer is made of brass and has a thickness of one millimeter. By setting the washer, the stability of the installation of the mounting bolt 18 is further enhanced.

[0024] In this invention, in order to further enhance the rotational stability of the rotating rod 5, a ball bearing is provided on the inner wall of the support frame 4. The support frame 4 is rotatably connected to the rotating rod 5 through the ball bearing. By providing the ball bearing, the rotational stability of the rotating rod 5 is further enhanced.

[0025] In this invention, in order to further enhance the stability of the connection between the air duct 2 and the air box 1, four sets of reinforcing ribs are fixedly connected to the left side of the outer surface of the air duct 2. The left side of the reinforcing ribs is fixedly connected to the right side of the air box 1. By setting the reinforcing ribs, the stability of the connection between the air duct 2 and the air box 1 is further enhanced.

[0026] In this invention, in order to further enhance the stability of the rotation of the drive wheel 9, a connecting key is fixedly connected to the outer surface of the rotating shaft 8, and a connecting keyway adapted to the connecting key is opened on the inner wall of the drive wheel 9. The stability of the rotation of the drive wheel 9 is further enhanced by the cooperation between the connecting key and the keyway.

[0027] In this invention, in order to further enhance the rust resistance of the device, both the air guide box 1 and the air guide pipe 2 are made of Q235 steel, and the outer surfaces of both the air guide box 1 and the air guide pipe 2 are coated with anti-rust paint. By setting the materials of the device, the rust resistance of the device is further enhanced.

[0028] All electrical components mentioned in this article are connected to an external main controller and 220V AC mains power, and the main controller can be a conventional known device such as a computer that can control it.

[0029] In use, the device is installed on the generator set using mounting bolts 18. The drive motor 11 is started, and the drive motor 11 drives the drive wheel 9 to rotate via the rotating shaft 8. The drive wheel 9 drives the driven wheel 7 to rotate via the transmission belt 10. The driven wheel 7 drives the turbine fan 6 to rotate via the rotating rod 5. The turbine fan 6 blows air from the right side of the air duct 2 to the left side. The adjusting bolt 16 presses against the top air guide plate 13, and the spring 15 presses against the bottom air guide plate 13. The transmission plate 14 makes the three sets of air guide plates 13 work together. Rotating the adjusting bolt 16 changes the insertion height of the adjusting bolt 16. The adjusting bolt 16 presses against the air guide plate 13, and the tilt angle of the air guide plate 13 changes, thereby changing the blowing angle of the airflow.

[0030] In summary, the air guiding mechanism of this generator set, through the coordinated use of the drive motor 11, driven wheel 7, rotating shaft 8, driving wheel 9, and transmission belt 10, ensures that when the turbine fan 6 is running, the drive motor 11 drives the driving wheel 9 to rotate via the rotating shaft 8, the driving wheel 9 drives the driven wheel 7 to rotate via the transmission belt 10, and the driven wheel 7 drives the turbine fan 6 to rotate via the rotating rod 5. This allows the drive motor 11 to be located outside the air guiding duct 2, preventing the heat generated by the drive motor 11 from being directly blown to the generator set, further reducing the temperature of the air blown to the generator set by the device.

[0031] The air guiding mechanism of this generator set works in conjunction with the rotating pin 12, the air guide plate 13, the transmission plate 14, the spring 15, and the adjusting bolt 16. The adjusting bolt 16 presses against the top air guide plate 13, the spring 15 presses against the bottom air guide plate 13, and the transmission plate 14 links the three sets of air guide plates 13. When the insertion height of the adjusting bolt 16 changes, the tilt angle of the air guide plate 13 changes. This allows the operator to change the direction of the airflow guided by the air guide plate 13 by adjusting the bolt 16, making it easier for the operator to guide the airflow to the main heat-generating parts of the generator set, thus further improving the air guiding effect of the air guiding mechanism.

[0032] 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.
