Description

Technical Field

[0001] This invention relates to the field of generator technology, specifically to a mobile, dustproof, heat-dissipating, energy-saving diesel variable frequency generator set. Background Technology

[0002] A diesel generator set is a small power generation device that uses diesel fuel. It generates a high-temperature, high-pressure environment by compressing air, injecting diesel fuel into the cylinder and igniting it. The energy from combustion drives the piston to do work, rotating the crankshaft. The generator then uses the mechanical energy of the crankshaft to drive the rotor, converting the mechanical energy into electrical energy through electromagnetic induction, thus outputting alternating current. It features high efficiency, high reliability, rapid start-up, and wide adaptability, and is widely used in backup power, emergency power supply, construction sites, and remote areas.

[0003] For example, a lightweight and easily detachable diesel generator set, as disclosed in Chinese Patent Publication No. CN215000570U, includes: a base and a diesel generator set body. The base has a top plate on its top, a first mounting hole inside the top plate, a support member on the top of the top plate, a fixing plate on the top of the support member, a second mounting hole inside the fixing plate, and mounting feet at the bottom of the diesel generator set body.

[0004] Currently, in existing technologies, most generators are exposed to the outside. When generators are working, they generate noise, which is difficult to reduce and affects the surrounding environment. Summary of the Invention

[0005] To solve the above-mentioned technical problems, the present invention is implemented through the following technical solution:

[0006] A mobile, dustproof, heat-dissipating, energy-saving diesel inverter generator set, comprising:

[0007] The base and the diesel engine are fixedly installed on the top side of the base. Rollers are rolled on the bottom side of the base so that the generator set can be moved to a designated position. A heat dissipation mechanism is installed between the surface of the base and the diesel engine.

[0008] The generator assembly includes a base and a cover. The base is mounted on the top of a base and away from the diesel engine. The cover is mounted on top of the base. A frequency converter is fixedly mounted on the side of the cover surface. A generator is installed in the middle of the inner cavity of the cover. An insert plate is fixedly mounted on the side of the inner wall of the cover near the bottom. A limit notch is provided at the bottom of the insert plate. A sound insulation board is fixedly connected to the inner side of the cover. A curled plate is fixedly mounted on the inner side of the sound insulation board. As noise propagates, the curled plate is evenly distributed on the inner side of the sound insulation board. During the propagation process, the noise comes into contact with the curled surface of the curled plate, reflecting, dispersing, and weakening the noise energy. The noise is enveloped by the sound insulation board, thus achieving sound insulation and reducing noise propagation.

[0009] Preferably, there are four rollers, and the four rollers are evenly distributed on the side of the bottom of the base.

[0010] Preferably, the rotating shaft at the center of the generator is rotatably mounted between the generator and the inner wall of the housing, the rotating shaft at the center of the generator passes through the inner wall of the housing and extends to its outside, and the rotating shaft at the center of the generator is fixedly mounted to the output end of the diesel engine by screws.

[0011] Preferably, the insert plates are installed vertically, there are four insert plates, and the four insert plates are evenly distributed on the side of the inner wall of the cover and near the bottom position, and the curled plates are evenly distributed on the inner side of the sound insulation plate.

[0012] Preferably, the bottom shell includes a rectangular support shell. The bottom of the rectangular support shell is fixedly installed to the top of the base and the end away from the diesel engine by screws. The bottom of the cover is fixedly installed to the top of the rectangular support shell. A square air intake pipe is connected to the surface of the rectangular support shell and the side closest to the diesel engine. A threaded post is fixedly installed on the side of the bottom of the rectangular support shell. A round hole on the surface of the bottom connecting ear of the generator passes through the threaded post. A hexagonal nut is threaded onto the top of the threaded post. The rotation of the output end of the diesel engine can drive the central shaft of the generator to rotate. The rotor at the center of the generator rotates to generate electricity, which is then frequency-converted by a frequency converter. By installing the generator at the center of the cover and at the top of the rectangular support shell, the generator is in a closed space, which reduces the transmission of noise during operation. The cover also protects the generator from dust, reducing the entry of dust into the interior and providing a dustproof effect.

[0013] Preferably, the threaded post is installed vertically, the bottom end of the insert plate is inserted into the interior of the rectangular support housing, the inner side of the limiting notch is in contact with the surface of the hexagonal nut, the threaded post passes through the round hole on the bottom connecting ear surface of the generator, and the hexagonal nut and the threaded post are threaded together to fix the generator, which is not easy to shake. This not only helps to reduce noise from the sound source, but also makes the generator less prone to damage and helps to generate electricity.

[0014] By inserting the insert plate into the rectangular support housing and embedding the hexagonal nut into the limiting notch, the hexagonal nut can be locked in place, making it less likely for the hexagonal nut to come loose.

[0015] Preferably, the heat dissipation mechanism includes a water tank and fan blades. The water tank is fixedly installed on the end face of the base surface near the diesel engine. The fan blades are fixedly installed on the surface of the diesel engine output shaft near the water tank. A right-angle pipe connects the top of the water tank and the top of the diesel engine. A heat-conducting plate is fixedly connected to the surface of the water tank. A concentrator is fixedly installed on the surface of the water tank away from the fan blades. A cooler is installed at the air outlet at the bottom of the concentrator. As the diesel engine runs normally, the coolant in the water tank can be drawn out, and the coolant can flow through the surface pipes of the diesel engine. The heat generated by the diesel engine during operation is absorbed and carried away by heat transfer, and the coolant flows back into the water tank for circulation and heat dissipation. The heat-conducting plate conducts heat to the water tank, dissipating the heat absorbed by the coolant. Combined with the output shaft of the diesel engine driving the fan blades to rotate, air is blown onto the heat-conducting plate, and the heat dissipation is accelerated by airflow.

[0016] Preferably, the surface of the fan blades is an arc-shaped curved surface. The fan blades are evenly distributed on the surface of the diesel engine output shaft and near the water tank. The air-collecting hopper is connected to the cooler. The heat-conducting plates are evenly distributed on the surface of the water tank. By rotating the fan blades, the air is blown. Under the guidance of the air-collecting hopper, the gas enters the interior of the cooler, cooling the hot gas and lowering its temperature. By connecting the air outlet of the cooler with the air inlet of the square air inlet pipe, the cold gas can enter the inner cavity formed by the rectangular support shell and the cover, thus cooling the generator. The gas is discharged from the gap between the rectangular support shell and the cover.

[0017] Preferably, an auxiliary mechanism is installed on the top of the base, which is installed between the diesel engine and the generator. The auxiliary mechanism includes a bracket, the bottom of which is fixedly installed to the top of the base by screws. A lower bearing is fixedly installed on the top of the bracket, and an upper bearing is detachably fixedly installed on the top of the lower bearing. Cylindrical balls are rolledly installed in the middle of the inner cavity of both the lower and upper bearings. Sealing strips are installed on the sides of the inner surfaces of both the lower and upper bearings. By supporting the connection between the output end of the diesel engine and the central shaft of the generator through the lower bearing, concentric shaft rotation can be formed. Rolling support is achieved by the outer surface of the cylindrical balls fitting against the flange edge of the connection between the output end of the diesel engine and the central shaft of the generator. Rolling friction is used to reduce frictional resistance, and the sealing strips reduce the entry of external dust into the interior, making the connection between the output end of the diesel engine and the central shaft of the generator rotate smoothly and less prone to jamming.

[0018] Preferably, the lower bearing and the upper bearing cover the connection between the output end of the diesel engine and the central shaft of the generator, the cylindrical balls are evenly distributed in the middle of the inner cavity of the lower bearing and the middle of the inner cavity of the upper bearing, and the sealing strip is made of rubber.

[0019] This invention provides a mobile, dustproof, heat-dissipating, and energy-saving diesel inverter generator set. It has the following beneficial effects:

[0020] 1. This mobile dustproof and heat-dissipating energy-saving diesel variable frequency generator set utilizes the generator installed in the center of the casing and combined with the generator being installed on the top of the rectangular support casing, so that the generator is in a closed space, which can reduce the transmission of noise when the generator is working, and the casing protects the generator, which can reduce the entry of dust into the interior, thus achieving a dustproof effect.

[0021] Second, this mobile dustproof and heat-dissipating energy-saving diesel variable frequency generator set utilizes the evenly distributed curled plates on the inner side of the sound insulation board as noise propagates. During the propagation process, the noise comes into contact with the curled surface of the curled plate, reflecting, dispersing and weakening the noise energy. Moreover, the noise is covered by the sound insulation board, thus achieving sound insulation and reducing noise propagation.

[0022] Third, this mobile dustproof, heat dissipation, and energy-saving diesel variable frequency generator set can be fixed by passing a threaded post through the round hole on the bottom connecting ear surface of the generator and threading a hexagonal nut to the threaded post. This prevents the generator from shaking, reduces noise from the source, and makes the generator less prone to damage, thus contributing to power generation.

[0023] Fourth, this mobile dustproof, heat dissipation, and energy-saving diesel variable frequency generator set can be secured by inserting a plug plate into the rectangular support housing and embedding a hexagonal nut into the limiting notch, making it less likely for the hexagonal nut to come loose.

[0024] 5. This mobile dustproof and heat-dissipating energy-saving diesel variable frequency generator set absorbs and removes the heat generated by the diesel engine during operation through heat transfer, allowing the coolant to flow back into the water tank for circulation and heat dissipation. The heat is also conducted to the water tank through heat-conducting fins, dissipating the heat absorbed by the coolant. In conjunction with the output shaft of the diesel engine driving the fan blades to rotate, air is blown onto the heat-conducting fins, accelerating heat dissipation through airflow.

[0025] VI. This mobile dustproof and heat-dissipating energy-saving diesel variable frequency generator set, under the guidance of the air-collecting hopper, allows gas to enter the interior of the cooler, cooling the hot gas and lowering its temperature. By connecting the air outlet of the cooler with the air inlet of the square air inlet pipe, the cold gas can enter the inner cavity composed of the rectangular support shell and the cover, thus cooling the generator. The gas is discharged from the gap between the rectangular support shell and the cover.

[0026] VII. This mobile dustproof and heat-dissipating energy-saving diesel variable frequency generator set utilizes the lower bearing to support the connection between the diesel engine's output end and the generator's central shaft, thus forming a concentric shaft rotation. Furthermore, by using the outer surface of the cylindrical ball bearings to fit against the flange edge at the connection between the diesel engine's output end and the generator's central shaft, rolling support is achieved. This rolling friction reduces frictional resistance, and the sealing strip further reduces the entry of external dust into the interior, ensuring smooth rotation between the diesel engine's output end and the generator's central shaft and preventing jamming.

[0037] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0038] For the first embodiment, please refer to... Figures 1-5 The present invention provides a technical solution:

[0039] A mobile, dustproof, heat-dissipating, energy-saving diesel inverter generator set, comprising:

[0040] The base 1 and the diesel engine 3 are fixedly installed on the top side of the base 1. Rollers 2 are rolled on the bottom side of the base 1. The rollers 2 can roll to facilitate the transfer of the generator set to the designated position. A heat dissipation mechanism 4 is installed between the surface of the base 1 and the diesel engine 3.

[0041] There are four rollers 2, and the four rollers 2 are evenly distributed on the side of the bottom of the base 1.

[0042] The power generation assembly 5 includes a base shell 51 and a cover shell 52. The base shell 51 is installed on the top of the base 1 and away from the diesel engine 3. The cover shell 52 is installed on the top of the base shell 51. A frequency converter 53 is fixedly installed on the side of the surface of the cover shell 52. A generator 54 is installed in the middle of the inner cavity of the cover shell 52. An insert plate 55 is fixedly installed on the side of the inner wall of the cover shell 52 and near the bottom. A limit notch 56 is opened at the bottom of the insert plate 55. A sound insulation plate 57 is fixedly connected to the inner side of the cover shell 52. A curled plate 58 is fixedly installed on the inner side of the sound insulation plate 57. When the generator 54 is working, it generates noise. As the noise propagates, the curled plate 58 is evenly distributed on the inner side of the sound insulation plate 57. During the propagation process, the noise comes into contact with the curled surface of the curled plate 58, which reflects, disperses and weakens the noise energy. The noise is covered by the sound insulation plate 57, which can achieve sound insulation and reduce the propagation of noise.

[0043] The rotating shaft at the center of the generator 54 is rotatably mounted between the inner wall of the housing 52 and the inner wall of the housing 52. The rotating shaft at the center of the generator 54 passes through the inner wall of the housing 52 and extends to its outside. The rotating shaft at the center of the generator 54 is fixedly mounted to the output end of the diesel engine 3 by screws.

[0044] The insert plates 55 are installed vertically. There are four insert plates 55, and the four insert plates 55 are evenly distributed on the side of the inner wall of the cover 52 and near the bottom. The curled plates 58 are evenly distributed on the inner side of the sound insulation plate 57.

[0045] The base shell 51 includes a rectangular support shell 511. The bottom of the rectangular support shell 511 is fixedly installed to the top of the base 1 and the end away from the diesel engine 3 by screws. The bottom of the cover 52 is fixedly installed to the top of the rectangular support shell 511. A square air intake pipe 512 is connected to the surface of the rectangular support shell 511 and the side closest to the diesel engine 3. A threaded post 513 is fixedly installed on the side of the bottom of the rectangular support shell 511. A round hole on the surface of the bottom connecting lug of the generator 54 passes through the threaded post 513. A hexagonal nut 514 is threaded onto the top of the threaded post 513. The operator starts the diesel engine 3 to work. The rotation of the output end of the diesel engine 3 drives the central shaft of the generator 54 to rotate. The rotor at the center of the generator 54 rotates to generate electricity, which is then converted into frequency by the frequency converter 53. The generator 54 is installed at the center of the housing 52 and on top of the rectangular support housing 511, so that the generator 54 is in a closed space, which can reduce the transmission of noise when the generator 54 is working. The housing 52 protects the generator 54 and reduces the amount of dust entering the interior, thus achieving a dustproof effect.

[0046] The threaded post 513 is installed vertically, and the bottom end of the insert plate 55 is inserted into the interior of the rectangular support housing 511. The inner side of the limiting notch 56 fits against the surface of the hexagonal nut 514. The threaded post 513 passes through the round hole on the bottom connecting ear surface of the generator 54, and the hexagonal nut 514 is threaded onto the threaded post 513, which can fix the generator 54 and prevent it from shaking. This not only helps to reduce noise from the sound source, but also makes the generator 54 less prone to damage and helps to generate electricity.

[0047] By inserting the insert plate 55 into the interior of the rectangular support housing 511 and embedding the hexagonal nut 514 into the interior of the limiting notch 56, the hexagonal nut 514 can be snapped in place, making it less likely for the hexagonal nut 514 to come loose.

[0048] The second embodiment is based on the first embodiment; please refer to [link / reference]. Figures 1 to 7 As shown:

[0049] The heat dissipation mechanism 4 includes a water tank 41 and a fan blade 42. The water tank 41 is fixedly installed on the end face of the base 1, close to the diesel engine 3. The fan blade 42 is fixedly installed on the surface of the output shaft of the diesel engine 3, close to the water tank 41. A right-angle pipe 43 connects the top of the water tank 41 and the top of the diesel engine 3. A heat-conducting fin 44 is fixedly connected to the surface of the water tank 41. A concentrator 45 is fixedly installed on the surface of the water tank 41, away from the end of the fan blade 42. A cooler 46 is installed at the air outlet at the bottom of the concentrator 45. When the diesel engine 3 is running normally, it can draw out the coolant from the water tank 41 and make the coolant flow through the surface pipes of the diesel engine 3. The heat generated by the diesel engine 3 during operation is absorbed and carried away by heat transfer, and the coolant flows back into the water tank 41 for circulation and heat dissipation. The heat is conducted to the water tank 41 through the heat conduction plate 44, and the heat absorbed by the coolant is discharged. Combined with the output shaft of the diesel engine 3 driving the fan blade 42 to rotate, the fan blade 42 blows air onto the heat conduction plate 44, and the heat dissipation is accelerated by the air flow.

[0050] The surface of the fan blade 42 is an arc-shaped curved surface. The fan blade 42 is evenly distributed on the surface of the output shaft of the diesel engine 3 and close to the water tank 41. The air concentrator 45 is connected to the cooler 46. The heat conduction plate 44 is evenly distributed on the surface of the water tank 41.

[0051] The rotation of the fan blades 42 blows air, which, guided by the air-collecting hopper 45, enters the interior of the cooler 46, cooling the hot air and lowering its temperature. By connecting the air outlet of the cooler 46 with the air inlet of the square air inlet pipe 512, the cold air can enter the cavity formed by the rectangular support housing 511 and the cover 52, thus cooling the generator 54. The air is then discharged from the gap between the rectangular support housing 511 and the cover 52.

[0052] The third embodiment is based on the first and second embodiments; please refer to [link / reference]. Figures 1 to 9 As shown:

[0053] An auxiliary mechanism 6 is installed on the top of the base 1. The auxiliary mechanism 6 is installed between the diesel engine 3 and the generator 54. The auxiliary mechanism 6 includes a bracket 61. The bottom of the bracket 61 is fixedly installed to the top of the base 1 by screws. A lower bearing 62 is fixedly installed on the top of the bracket 61. An upper bearing 63 is detachably fixedly installed on the top of the lower bearing 62. Cylindrical balls 64 are rolled in the middle of the inner cavity of both the lower bearing 62 and the upper bearing 63. Sealing strips 65 are installed on the sides of the inner surfaces of both the lower bearing 62 and the upper bearing 63. With the support of 61, the lower bearing 62 supports the connection between the output end of the diesel engine 3 and the central shaft of the generator 54, thus forming a concentric shaft rotation. By utilizing the outer surface of the cylindrical ball bearing 64 to fit against the flange edge at the connection between the output end of the diesel engine 3 and the central shaft of the generator 54, rolling support can be achieved. Rolling friction is used to reduce frictional resistance, and with the sealing strip 65, external dust is reduced from entering the interior, making the connection between the output end of the diesel engine 3 and the central shaft of the generator 54 rotate smoothly and less prone to jamming.

[0054] The lower bearing 62 and the upper bearing 63 enclose the connection between the output end of the diesel engine 3 and the central shaft of the generator 54. Cylindrical balls 64 are evenly distributed in the middle of the inner cavity of the lower bearing 62 and the middle of the inner cavity of the upper bearing 63. The sealing strip 65 is made of rubber.

[0055] In use, first install the generator 54 at the bottom of the inner cavity of the rectangular support housing 511, and pass the threaded post 513 through the round hole on the bottom connecting ear surface of the generator 54. Then, thread the hexagonal nut 514 to the threaded post 513 to fix the generator 54 in place, making it less prone to shaking. Finally, cover the surface of the generator 54 with the cover 52.

[0056] At this time, open the top cover of the cover 52, insert the insert plate 55 into the inside of the rectangular support housing 511, and embed the hexagonal nut 514 into the inside of the limiting notch 56 to lock the hexagonal nut 514, making it less likely for the hexagonal nut 514 to come loose. Then fix the cover 52 and the rectangular support housing 511 with screws, close the top cover of the cover 52, install the upper bearing 63 on top of the lower bearing 62, and the roller 2 can roll to facilitate the transfer of the generator set to the designated location.

[0057] The staff starts the diesel engine 3 to work. The rotation of the output end of the diesel engine 3 drives the central shaft of the generator 54 to rotate. The rotor at the center of the generator 54 rotates to generate electricity, which is then converted into frequency by the frequency converter 53. As noise propagates, the curled plates 58 are evenly distributed on the inner side of the sound insulation plate 57. During the propagation process, the noise comes into contact with the curled surface of the curled plates 58, which reflects, disperses and weakens the noise energy. The noise is also covered by the sound insulation plate 57, which can achieve sound insulation and reduce the propagation of noise.

[0058] Meanwhile, the generator 54 is installed at the center of the housing 52 and is also installed on the top of the rectangular support housing 511, so that the generator 54 is in a closed space, which can reduce the transmission of noise when the generator 54 is working, and the protection of the generator 54 by the housing 52 can reduce the entry of dust into the interior.

[0059] Furthermore, with the support of bracket 61, the lower bearing 62 supports the connection between the output end of diesel engine 3 and the central shaft of generator 54, thus forming a concentric shaft rotation. By utilizing the outer surface of cylindrical ball bearing 64 to fit against the flange edge at the connection between the output end of diesel engine 3 and the central shaft of generator 54, rolling support can be achieved. Rolling friction is used to reduce frictional resistance, and with the sealing strip 65, external dust is reduced from entering the interior, making the connection between the output end of diesel engine 3 and the central shaft of generator 54 rotate smoothly and less prone to jamming.

[0060] Furthermore, as the diesel engine 3 operates normally, the coolant in the water tank 41 can be drawn out, and the coolant water flows through the surface pipes of the diesel engine 3. The heat generated by the diesel engine 3 during operation is absorbed and carried away by heat transfer, and the coolant flows back into the water tank 41 for circulation and heat dissipation. The heat is conducted to the water tank 41 through the heat conduction plate 44, and the heat absorbed by the coolant is discharged. Combined with the output shaft of the diesel engine 3 driving the fan blade 42 to rotate, the heat conduction plate 44 is blown with air, and the heat dissipation is accelerated through air flow.

[0061] The rotation of the fan blades 42 blows air, which, guided by the air-collecting hopper 45, enters the interior of the cooler 46, cooling the hot air and lowering its temperature. By connecting the air outlet of the cooler 46 with the air inlet of the square air inlet pipe 512, the cold air can enter the cavity formed by the rectangular support housing 511 and the cover 52, thus cooling the generator 54. The air is then discharged from the gap between the rectangular support housing 511 and the cover 52.
