Abstract
Description
Technical Field
[0001] This utility model belongs to the field of generator technology, specifically relating to an ultra-quiet diesel generator set. Background Technology
[0002] A diesel generator is a small power generation device that uses diesel fuel and a diesel engine as the prime mover to drive a generator to generate electricity.
[0003] Many small generators are directly supported on the ground during operation. The vibration generated by the cylinder inside the generator during operation can cause the entire generator to shift, which increases the noise generated during operation. In some working environments, there may be water on the ground where the generator is placed. The presence of water reduces the friction between the generator's support and the ground, resulting in greater noise from vibration. Therefore, this application proposes an ultra-quiet diesel generator set. Utility Model Content
[0004] The purpose of this invention is to provide an ultra-quiet diesel generator set to solve the problems mentioned in the background art, such as the increased noise generated during generator operation due to generator displacement, and the presence of uncleaned water on the ground where the generator is placed in some working environments. The presence of water reduces the friction between the generator's bottom support and the ground, resulting in greater noise from the generator due to vibration.
[0005] To achieve the above objectives, this utility model provides the following technical solution: an ultra-quiet diesel generator set, including a generator set and a bracket, wherein the generator set is mounted on the bracket;
[0006] The bracket is provided with a support leg and a mounting base that is detachably connected to the bracket and rotatably engaged with the support leg;
[0007] The mounting base and the support leg are rotatably coupled via a pivot, and the bottom of the support leg is provided with a support plate for supporting the ground;
[0008] The support plate is provided in at least two parts, and the multiple support plates are symmetrically distributed on both sides of the bracket;
[0009] A connecting shaft is inserted into the support leg, and a horizontally distributed frame is provided at the support leg. A sliding groove that slides with the connecting shaft is provided in the horizontal frame, and a lifting unit is provided at the horizontal frame.
[0010] The support plate is provided with a connecting frame, an air pump installed on the connecting frame, an exhaust pipe connected to the air pump, and an exhaust hole connected to the exhaust pipe and passing through the support plate.
[0011] Preferably, the bracket is provided with four square-distributed casters at the bottom, and the casters are equipped with steering and braking functions.
[0012] Preferably, the mounting base includes two connecting blocks, each with an arc-shaped groove that mates with the bracket, and the two connecting blocks are connected by bolts.
[0013] Preferably, there are two legs on one side, with the two legs located on opposite sides of the mounting base, and the support plate located between the two legs.
[0014] Preferably, a lifting frame connected to the horizontal frame and a lifting plate installed above the lifting frame are provided between the horizontal frame and the lifting unit, and the lifting plate is connected to the lifting unit.
[0015] Preferably, there are two lifting frames, which are located on the front and rear sides of the outriggers.
[0016] Preferably, a connecting sleeve is provided at the bracket, and a connecting plate is provided at the connecting sleeve.
[0017] Preferably, the connecting sleeve slides with the bracket, and a pin for fixing is inserted into the connecting sleeve.
[0018] Preferably, the connecting plate is provided with a movable sliding plate.
[0019] Preferably, the push-pull plate is located in the middle of the connecting plate, and a handle for gripping is provided on the push-pull plate.
[0020] Beneficial effects:
[0021] I. The ultra-quiet diesel generator set provided by this utility model has a lifting unit that can drive the horizontal frame to move up and down. When the horizontal frame moves up, it can pull the outriggers around the mounting base through the connecting shaft. At this time, the support plate is separated from the ground, and the bracket will not be obstructed by the support plate or other components during the movement. When the lifting unit drives the horizontal frame down, it can push the outriggers around the mounting base through the connecting shaft. At this time, the support plate presses on the ground and supports the ground. The generator set is stable due to the joint support of the support plate and the casters in the bracket. It is not easy to cause large displacement due to its own shaking, thereby reducing the noise generated during the operation of the generator set and improving the quietness performance of the generator set.
[0022] II. The ultra-quiet diesel generator set provided by this utility model has exhaust ports that are distributed from the middle of the support plate to both sides. That is, the exhaust ports are tilted away from the center of the support plate, and the tilt angle is smaller the closer to the center of the support plate. In this way, when the air pump is working, it can form an airflow from the middle of the support plate to both sides. The airflow can blow away the water at the bottom of the support plate, allowing the support plate to directly contact the ground. This avoids the water on the ground causing the support plate to lose friction, which would lead to the displacement of the support plate and bracket during operation. Attached Figure Description

[0029] The specific embodiments of this utility model are described in detail below, but it should be understood that the protection scope of this utility model is not limited to the specific embodiments.
[0030] like Figures 1-4 As shown, the ultra-quiet diesel generator set provided in this embodiment of the present invention includes a generator set 1 and a bracket 2. The generator set 1 is mounted on the bracket 2. The generator set 1 uses diesel as power. The bottom of the bracket 2 is provided with four square-distributed casters 3, which are equipped with steering and braking functions.
[0031] During operation, the internal cylinder of generator set 1 will vibrate due to rotation. This vibration will generate noise and cause the bracket 2 to shift. In order to reduce the vibration of bracket 2 and thus reduce noise, a support leg 4 is provided at bracket 2, and a mounting seat is detachably connected to bracket 2 and rotates with support leg 4. The mounting seat includes two connecting blocks, and the connecting blocks are provided with arc-shaped grooves that cooperate with bracket 2. The two connecting blocks are connected by bolts.
[0032] Specifically, the mounting base and the support leg 4 are rotatably connected via a pivot, and the bottom of the support leg 4 is provided with a support plate 5 for supporting the ground. The support plate 5 supports the ground, which can increase the contact area between the bracket 2 and the ground, improve the stability of the bracket 2, and reduce the vibration caused to the bracket 2 during the operation of the generator set 1.
[0033] It should be noted that there are at least two support plates 5, and multiple support plates 5 are symmetrically distributed on both sides of the bracket 2. There are two legs 4 on each side, and the two legs 4 are located on both sides of the mounting base, with the support plate 5 located between the two legs 4.
[0034] Specifically, a connecting shaft is inserted into the outrigger 4, and a transverse frame 6 is provided at the outrigger 4. A sliding groove is provided in the transverse frame 6 to slide with the connecting shaft. A lifting unit 9 is provided at the transverse frame 6. The lifting unit 9 can be a hydraulic cylinder. The hydraulic cylinder can be a manually operated hydraulic cylinder or an electrically driven hydraulic cylinder. However, if an electrically driven hydraulic cylinder is used, a power supply and controller need to be provided at the bracket 2.
[0035] The lifting unit 9 can drive the horizontal frame 6 to move up and down. When the horizontal frame 6 moves up, it can pull the support leg 4 around the mounting base through the connecting shaft. At this time, the support plate 5 is separated from the ground. The bracket 2 will not be obstructed by the support plate 5 and other components during the movement. The lifting unit 9 drives the horizontal frame 6 to move down. It can push the support leg 4 around the mounting base through the connecting shaft. At this time, the support plate 5 presses on the ground and supports the ground. The generator set 1 is stable due to the joint support of the support plate 5 and the casters 3 in the bracket 2. It is not easy to cause large displacement due to its own shaking, which reduces the noise generated during the operation of the generator set 1 and improves the quietness performance of the generator set 1.
[0036] For reference Figure 2 , Figure 3 A lifting frame 7 connected to the horizontal frame 6 and a lifting plate 8 installed above the lifting frame 7 are provided between the horizontal frame 6 and the lifting unit 9. The lifting plate 8 is connected to the lifting unit 9. There are two lifting frames 7, and the two lifting frames 7 are located on the front and rear sides of the support leg 4 respectively.
[0037] In some usage scenarios, there is water accumulation on the ground. The support plate 5 supports the ground, and the water accumulation reduces the friction between the support plate 5 and the ground, which can easily cause the bracket 2 to shift. Therefore, a connecting frame, an air pump 10 mounted on the connecting frame, an exhaust pipe 11 connected to the air pump 10, and an exhaust hole 12 connected to the exhaust pipe 11 and passing through the support plate 5 are provided at the support plate 5. The exhaust hole 12 is distributed from the middle of the support plate 5 to both sides, that is, the exhaust hole 12 is tilted away from the center of the support plate 5, and the angle of tilt is smaller as it approaches the center of the support plate 5. In this way, when the air pump 10 is working, it can form an airflow from the middle of the support plate 5 to both sides. The airflow can blow away the water at the bottom of the support plate 5, allowing the support plate 5 to directly contact the ground and avoid the water on the ground causing the friction of the support plate 5 to decrease, which could lead to the displacement of the support plate 5 and the bracket 2 during operation.
[0038] Specifically, a connecting sleeve 13 is provided at bracket 2, which slides with bracket 2, and a pin for fixing is inserted into the connecting sleeve 13. A connecting plate 14 is provided at connecting sleeve 13, and a sliding plate 15 is provided at connecting plate 14. The sliding plate 15 is located at the middle position of connecting plate 14, and a handle 16 for gripping is provided at sliding plate 15.
[0039] In summary, this utility model embodiment provides an ultra-quiet diesel generator set. The lifting unit 9 can drive the horizontal frame 6 to move up and down. When the horizontal frame 6 moves up, it can pull the outrigger 4 around the mounting base through the connecting shaft. At this time, the support plate 5 is separated from the ground, and the bracket 2 will not be obstructed by the support plate 5 and other components during the movement. When the lifting unit 9 drives the horizontal frame 6 to move down, it can push the outrigger 4 around the mounting base through the connecting shaft. At this time, the support plate 5 presses on the ground and supports the ground. The generator set 1, supported by the support plate 5 and the casters 3 in the bracket 2, is stable and is not easy to move significantly due to its own shaking, thereby reducing the noise generated by the generator set 1 during operation and improving the quietness performance of the generator set 1.
[0040] The exhaust holes 12 are distributed from the middle of the support plate 5 to both sides, that is, the exhaust holes 12 are tilted away from the center of the support plate 5, and the tilt angle is smaller the closer to the center of the support plate 5. In this way, when the air pump 10 is working, it can form an airflow from the middle of the support plate 5 to both sides. The airflow can blow away the water at the bottom of the support plate 5, allowing the support plate 5 to directly contact the ground, avoiding the water on the ground from causing the friction of the support plate 5 to decrease, which would lead to the displacement of the support plate 5 and the bracket 2 during operation.
[0041] The above-disclosed embodiments are only a few specific examples of the present utility model. However, the embodiments of the present utility model are not limited thereto. Any changes that can be conceived by those skilled in the art should fall within the protection scope of the present utility model.
