Description

Technical Field

[0001] This application relates to the field of power generation equipment technology, and more particularly to a power generation device. Background Technology

[0002] A generator produces electricity by consuming fuel oil, thus providing temporary power. A generator mainly consists of a generator and an engine. The engine drives the generator to rotate, converting the chemical energy of the fuel into mechanical energy, and the generator converts that mechanical energy into electrical energy.

[0003] Among related technologies, generators are relatively noisy when running. Utility Model Content

[0004] This application provides a power generation device that can improve the technical problem of excessive noise in power generation devices.

[0005] This application provides a power generation device, which includes a housing, a power generation component, a controller, an output terminal, a soundproof cover, and a first soundproofing component. The power generation component is disposed within the housing and includes an engine and a generator. The generator is drively connected to the engine, and the engine can drive the generator to rotate to generate electricity. The controller is disposed within the housing and is electrically connected to both the engine and the generator. The controller can control the output voltage or output power of the generator. The output terminal is disposed on the housing and is electrically connected to the generator. The output terminal is used to connect external electrical equipment. The soundproof cover is disposed over the cylinder head of the engine. The first soundproofing component is disposed between the soundproof cover and the cylinder head of the engine, and the first soundproofing component abuts against both the inner surface of the soundproof cover and the cylinder head of the engine.

[0006] Beneficial effects: By installing a soundproof cover on the engine cylinder head, the most significant high-frequency mechanical and combustion noise of the engine can be precisely suppressed, resulting in good sound insulation. Additionally, the soundproof cover also provides heat insulation, blocking radiant heat from the cylinder head surface and protecting the wiring harnesses and plastic components around the cylinder head. Adding a first soundproofing component between the soundproof cover and the cylinder head further enhances the sound insulation effect, reducing noise during generator operation, and the first soundproofing component prevents the soundproof cover from rigidly contacting the cylinder head and transmitting vibrations.

[0029] Furthermore, the technical solutions of the various embodiments of this application can be combined with each other, but only if they are based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the scope of protection claimed by this application.

[0030] like Figure 1-3 As shown, this application embodiment provides a power generation device 100, which includes a power generation component 120 and a housing 130.

[0031] The power generation assembly 120 is used for generating electricity. The power generation assembly 120 includes an engine 122, a generator 125, etc. The engine 122 rotates by burning fuel. The engine 122 is connected to the generator 125 via a transmission connection, and the engine 122 can drive the generator 125 to rotate, thereby generating electricity. Optionally, the engine 122 and the generator 125 are integrated into one unit, making the structure of the power generation assembly 120 more compact and the size of the power generation device 100 smaller. The engine 122 can be a gasoline engine, diesel engine, natural gas engine, etc., and the generator 125 can be an AC generator 125, a DC generator 125, etc.

[0032] The housing 130 includes a top shell 1311, side shells 132, and a bottom shell 1331. The top of the side shell 132 is connected to the top shell 1311, and the bottom of the side shell 132 is connected to the bottom shell 1331. The housing 130 can prevent external debris and rainwater from entering the interior of the power generation equipment 100, thus providing a certain degree of dust and water protection, and protecting the power generation component 120 from accidental collisions, compression, or damage during handling. In addition, the housing 130 also has a certain noise reduction effect, which can isolate the noise generated by the operation of the power generation component 120 to a certain extent.

[0033] Alternatively, the housing 130 can be made of plastic, which is lightweight, low-cost, and easy to process, allowing it to be injection molded into various complex shapes and providing insulation. Alternatively, the housing 130 can be made of metal, which provides better heat dissipation performance, assisting the power generation component 120 in heat dissipation, and also has high strength, good load-bearing capacity, is not easily damaged, and has a long service life.

[0034] In some embodiments, the power generation equipment 100 includes a controller electrically connected to both the engine 122 and the generator 125. The controller can control the output voltage or output power of the generator 125, for example, by adjusting the output voltage using a transformer module, or by adjusting the output power of the generator 125 by changing the output power of the engine 122. Optionally, the controller can also control the start and stop of the engine 122, and provide overload protection, high-temperature protection, etc., for the engine 122.

[0035] like Figure 2 and Figure 3 As shown, in some embodiments, the power generation device 100 further includes a frame 110 disposed within a housing 130, with the housing 130 covering the frame 110. For example, a top shell 1311, side shells 132, and a bottom shell 1331 cover different parts of the frame 110. Optionally, the top shell 1311 covers the top of the frame 110, the side shells 132 cover the sides of the frame 110, and the bottom shell 1331 covers the bottom of the frame 110. The frame 110, as the internal skeleton of the power generation device 100, can improve the rigidity of the power generation device 100. The engine 122 and generator 125 will vibrate during operation; the frame 110 can reduce the deformation caused by vibration, lower the overall vibration level of the power generation device 100, and reduce the vibration and noise transmitted by the power generation device 100. Furthermore, the frame 110 itself has a higher natural frequency, making it less likely to resonate with the power generation component 120.

[0036] The power generation component 120 is at least partially disposed within the frame 110, which provides a solid mounting foundation for the power generation component 120, making it less prone to displacement during operation and transportation. The connection method between the power generation component 120 and the frame 110 can be, for example, screwing, snap-fitting, bonding, welding, etc., and is not limited thereto.

[0037] like Figure 2 and Figure 3 As shown, in some embodiments, the side shell 132 includes a first side plate 1323, a second side plate 1324, a third side plate 1325, and a fourth side plate 1326, which are sequentially connected to form a cylindrical structure. Optionally, at least one of the first side plate 1323, the second side plate 1324, the third side plate 1325, and the fourth side plate 1326 is provided with reinforcing ribs to improve structural strength. Optionally, the areas of the first side plate 1323 and the third side plate 1325 are similar, and the areas of the second side plate 1324 and the fourth side plate 1326 are similar. Optionally, the areas of the first side plate 1323 and the third side plate 1325 are relatively large, and the areas of the second side plate 1324 and the fourth side plate 1326 are relatively small.

[0038] Optionally, both the second side plate 1324 and the fourth side plate 1326 are recessed to form transport grooves, allowing the user's fingers to be inserted into these grooves to facilitate lifting the generator 100 and thus making it easier for the user to move the generator 100. The distance between the second side plate 1324 and the fourth side plate 1326 is relatively large, allowing the user's arms to extend further, thus facilitating the user's exertion of force.

[0039] like Figure 4 and Figure 5 As shown, in some embodiments, the top of the side shell 132 has an abutment wall 1321 facing the top shell 1311. A water guide channel 132a and a drain outlet 132b communicating with the water guide channel 132a are provided on the abutment wall 1321. When rainwater seeps in from the gap between the side shell 132 and the top shell 1311, the rainwater flows into the water guide channel 132a. The water guide channel 132a collects the rainwater and guides it out through the drain outlet 132b, allowing the rainwater to flow along the guiding path of the water guide channel 132a instead of flowing randomly on the inner wall of the side shell 132. This avoids water-sensitive or critical components inside the power generation equipment 100, protecting these components and improving the reliability, safety, and service life of the power generation equipment 100. The power generation equipment 100 can be used outdoors without additional protective measures.

[0040] Optionally, the side shell 132 can be at least one of a first side shell 132, a second side shell 132, a third side shell 132, and a fourth side shell 132, that is, at least one of the first side plate 1323, the second side plate 1324, the third side plate 1325, and the fourth side plate 1326 is provided with a water guide groove 132a. Optionally, the drain outlet 132b is provided at both ends of the first side plate 1323 and the third side plate 1325 in the horizontal direction, so that rainwater flows down from the edges of the first side plate 1323 and the third side plate 1325. The edge positions of the first side plate 1323 and the third side plate 1325 (that is, the two ends near the second side plate 1324 and the fourth side plate 1326) are relatively moist, while most of the interior of the shell 130 can remain dry. Based on this, water-resistant components can be provided at the corresponding positions of the first side plate 1323 and the second side plate 1324. The first side plate 1323 and the second side plate 1324 can be in a wet state, and there is no need to provide a drain outlet 132b for the first side plate 1323 and the second side plate 1324.

[0041] like Figure 6As shown, rainwater discharged from drain outlet 132b flows down along the side shell 132 to the bottom shell 1331, or rainwater falls directly into the bottom shell 1331 after exiting drain outlet 132b. Drainage holes 133a are provided on the bottom shell 1331, allowing rainwater flowing into the bottom shell 1331 to drain through the drainage holes 133a, preventing rainwater from accumulating on the bottom shell 1331. Optionally, there can be multiple drainage holes 133a distributed in different parts of the bottom shell 1331, making it difficult for water to accumulate anywhere on the bottom shell 1331. Furthermore, while meeting drainage requirements, a single drainage hole 133a can be relatively small, having little impact on the structural strength of the shell 130.

[0042] like Figure 4 As shown, in some embodiments, a baffle plate 1322 is provided on the side shell 132, corresponding to the drain outlet 132b. The baffle plate 1322 can, on the one hand, prevent rainwater discharged from the drain outlet 132b from flowing into the other side of the baffle plate 1322, thereby limiting the flow path of the rainwater; on the other hand, it can prevent rainwater from other positions of the shell 130 from flowing into the other side of the baffle plate 1322. In addition, even if the power generation equipment 100 is in an inclined state, the baffle plate 1322 can still prevent rainwater from flowing into the other side of the baffle plate 1322.

[0043] Optionally, the drain outlet 132b is located at one end of the first side plate 1323 near the second side plate 1324, and the water baffle 1322 is located at the end of the drain outlet 132b away from the second side plate 1324, thereby preventing rainwater from flowing into the middle part of the first side plate 1323. Optionally, the drain outlet 132b is located at one end of the third side plate 1325 near the fourth side plate 1326, and the water baffle 1322 is located at the end of the drain outlet 132b away from the fourth side plate 1326, thereby preventing rainwater from flowing into the middle part of the third side plate 1325.

[0044] Optionally, the baffle 1322 extends from the drain outlet 132b to the bottom of the side shell 132, thereby continuously blocking rainwater. It is understood that the baffle 1322 is not used to limit the flow path of rainwater from the drain outlet 132b to the bottom shell 1331. Those skilled in the art can set it according to actual needs, which will not be elaborated here.

[0045] like Figures 7-9 and Figure 14As shown, in some embodiments, an exhaust port 130b is provided on the side shell 132. The exhaust port 130b can allow the engine 122 to discharge exhaust gas, and can also allow the power generation device 100 to blow hot air for heat dissipation. Exemplarily, the power generation device 100 includes a cooling fan 173, which can dissipate heat from the interior of the power generation device 100, thereby making the operation of the power generation device more stable. The hot air blown by the cooling fan 173 is discharged from the exhaust port 130b. Optionally, the exhaust port 130b is provided on the second side plate 1324.

[0046] Optionally, the exhaust gas and hot air from engine 122 can be discharged through different air ducts to reduce mutual interference. For example, the exhaust gas from engine 122 can be connected to the exhaust port 130b through a separate exhaust pipe. Since the exhaust gas from engine 122 is at a high temperature and contains pollutants, this arrangement ensures that the exhaust gas is completely discharged outside the housing 130, preventing exhaust gas from accumulating inside the housing 130 and extending the service life of the power generation equipment 100. Optionally, the exhaust pipe is positioned in the middle of the exhaust port 130b, allowing the hot air blown by the cooling fan 173 to dissipate heat from the exhaust pipe, thereby reducing heat radiation from the exhaust pipe.

[0047] Optionally, the power generation equipment 100 also includes a wind guide 150 disposed within the housing 130. The wind guide 150 includes a plurality of laterally extending first grilles 151, which are arranged vertically at intervals, and at least some of the first grilles 151 are inclined downward at the end near the exhaust port 130b. When rainwater drips onto the inclined first grilles 151, it will slide down under the influence of gravity and will not accumulate on the first grilles 151. That is, the wind guide 150 can improve waterproof performance and prevent rainwater from entering the housing 130 from the exhaust port 130b. Moreover, the inclined first grilles 151 are less likely to accumulate fallen leaves, mud, and other debris, which can reduce the risk of blockage. When water flows along the inclined first grilles 151, it can carry away some of the attached dirt, reducing the maintenance frequency. Finally, the inclined first grilles 151 can change the direction of exhaust, making the exhaust more likely to blow towards the ground, thus reducing the impact on users and making the exhaust noise perceived by users less.

[0048] like Figures 7-9 As shown, in some embodiments, the side shell 132 is provided with a plurality of vertically extending second grilles 1327, which are arranged sequentially at intervals along the lateral direction. The gaps between the plurality of second grilles 1327 together constitute the exhaust port 130b. The second grilles 1327 can block debris, preventing larger debris from entering the exhaust port 130b. The second grilles 1327 and the first grille 151 can vertically and horizontally separate the airflow, thereby making the airflow more dispersed and the noise lower.

[0049] like Figure 2 and Figure 10 As shown, in some embodiments, the power generation equipment 100 further includes an interface assembly 140. A first opening is provided on the side shell 132 corresponding to the interface assembly 140 to allow the interface assembly 140 to protrude outside the shell 130, thereby facilitating user access to the interface assembly 140. Optionally, the fourth side shell 132 is provided with a first opening to allow the interface assembly 140 to protrude from the exhaust port 130b, thus preventing the exhaust from the exhaust port 130b from affecting the interface assembly 140.

[0050] Optionally, the interface assembly 140 includes an output terminal 141 and a waterproof cover 142 detachably disposed on the output terminal 141. The waterproof cover 142 can cover the output terminal 141 to prevent rainwater from flowing into the output terminal 141, thus achieving a waterproof effect. The connection method between the output terminal 141 and the waterproof cover 142 can be, for example, a snap-fit ​​connection, a screw connection, a Velcro connection, or a magnetic connection. The output terminal 141 is used to connect to external electrical equipment to supply power to the external equipment. The output terminal 141 can be, for example, a two-prong socket or a three-prong socket.

[0051] like Figure 10 As shown, in some embodiments, the bottom of the side shell 132 is provided with a cable passage hole 132c, through which the interface assembly 140 is electrically connected to the plug, and the cable passage hole 132c allows the plug's cable to pass through. Since the plug's cable exits from the bottom, the side shell 132 can shield the cable, making it neater and more aesthetically pleasing, and rainwater cannot flow upwards from the cable passage hole 132c at the bottom, thus providing a waterproof effect.

[0052] like Figure 11 As shown, in some embodiments, the power generation assembly 120 also includes a fuel tank 121 with a gasoline drain port. The fuel tank 121 is positioned above the generator 125, and its gasoline drain port is higher than the fuel inlet of the engine 122. Fuel in the fuel tank 121 can flow into the fuel inlet of the engine 122 by gravity, thus eliminating the need for a fuel pump and its associated circuitry and control devices. Gravity can provide fuel pressure in real time, avoiding the time required for the fuel pump to build up pressure or potential vapor lock problems, resulting in more reliable starting after low temperatures or long periods of inactivity.

[0053] Fuel pumps are a common source of failure (such as motor burnout, pump blockage, and mechanical wear). Eliminating the fuel pump improves system reliability, simplifies the fuel supply system, and makes fault diagnosis and repair relatively easier. There is no need for regular inspection, testing, replacement, or repair of the fuel pump.

[0054] Optionally, such as Figure 2As shown, the fuel tank 121 includes a tank body 1211 and a tank cover 1212. The tank cover 1212 protrudes from the top shell 1311, thereby facilitating the user to open the tank cover 1212 to add fuel.

[0055] like Figure 11 As shown, in some embodiments, the power generation assembly 120 further includes a starter motor and a starter battery 124. The starter battery 124 is electrically connected to the starter motor and supplies power to the starter motor. The starter motor can bring the engine 122 from a stationary state to a running state to drive the engine 122 to start.

[0056] Users can start engine 122 simply by pressing a button, without any physical effort. Compared to manual starting, the starter motor improves the ease and success rate of starting, especially in cold weather or when engine 122 is not in good condition. The starter motor provides a smooth initial rotation, avoiding the impact and wear that may be caused to the internal parts of engine 122 by rough starting, and can accelerate engine 122 to a speed sufficient for ignition in a short time, reducing the time of dry friction during starting and thus reducing wear on engine 122.

[0057] like Figure 2 As shown, in some embodiments, the interface component 140 further includes a charging terminal 143, which is electrically connected to the startup battery 124. The charging terminal 143 is used to charge the startup battery 124 and serves as an external charging port for the startup battery 124.

[0058] The starter battery 124 will slowly self-discharge. After being left unattended for a long time, the starter battery 124 will gradually lose its charge, causing the engine 122 to fail to start electrically. Furthermore, deep discharge will severely damage the plates inside the battery, significantly shortening its lifespan.

[0059] The charging terminal 143 can charge the starter battery 124, facilitating user maintenance of the starter battery 124 and eliminating the hassle of periodically removing the starter battery 124 for external charging. The starter battery 124 can be kept fully charged, preventing the generator 125 from failing to start due to a depleted starter battery. A fully charged battery provides a strong starting current, ensuring the output torque of the starter motor, and can support multiple starting attempts.

[0060] Optionally, when the power generation equipment 100 is running, the generator 125 can charge the starting battery 124 to keep it fully charged as much as possible.

[0061] like Figure 12As shown, in some embodiments, the power generation assembly 120 also includes an air filter 123, which is connected to the air intake of the generator 125. The air filter 123 can filter dust and impurities in the air, making the air entering the engine 122 cleaner, thereby reducing the wear of the engine 122.

[0062] like Figure 11 As shown, in some embodiments, the side shell 132 includes a side plate, which can be one of a first side plate 1323, a second side plate 1324, a third side plate 1325, and a fourth side plate 1326. The engine 122 has an oil drain port and a spark plug 1221. At least two of the fuel drain port, oil drain port, spark plug 1221, air filter 123, and starter battery 124 are corresponding to the side plate, allowing the user to maintain multiple components of the fuel drain port, oil drain port, spark plug 1221, air filter 123, and starter battery 124 simply by removing the side plate. Optionally, the fuel drain port, oil drain port, spark plug 1221, air filter 123, and starter battery 124 are all corresponding to the side plate. When the side plate is opened, the user can maintain any one of the fuel drain port, oil drain port, spark plug 1221, air filter 123, and starter battery 124.

[0063] like Figure 11 As shown, in some embodiments, the power generation assembly 120 further includes an oil pipe and a shut-off element 127 disposed on the oil pipe. The engine 122 has an oil drain port, and the oil pipe is connected to the oil drain port. The shut-off element 127 can be, exemplarily, a valve or a plug. When changing the oil, the user only needs to lower the oil pipe and open the shut-off element 127 to drain the oil, which is convenient and avoids contaminating the oil.

[0064] In some embodiments, the power generation equipment 100 includes a water immersion sensor for detecting whether the power generation equipment 100 is flooded, thereby protecting the power generation equipment 100 and the user. The water immersion sensor is typically installed at the bottom of the housing 130 and can promptly issue an alarm or automatically shut down the machine before the water level reaches a dangerous height, cutting off the power supply to avoid electrical damage and reduce the risk of electric shock to the user.

[0065] In some embodiments, the power generation equipment 100 includes an access control sensor for detecting whether the housing 130 is opened, thereby protecting the power generation equipment 100 and the user. The access control sensor can be disposed on a detachable panel, for example, on the third side housing 132. When the panel is opened while the power generation equipment 100 is running, it can trigger an automatic shutdown to prevent personnel from accidentally contacting rotating parts, high-temperature surfaces, or live terminals, thus avoiding personal injury. The detachable panel can be at least one of the first side housing 132, the second side housing 132, the third side housing 132, and the detachable method can be screw connection, snap-fit ​​connection, Velcro connection, etc.

[0066] like Figure 2 and Figure 3 As shown, in some embodiments, the inverter 129 is located at the first air inlet 130a. The air at the air inlet is the lowest temperature air outside the unit that has not been heated. Placing the inverter 129 in this position ensures that it comes into contact with the low temperature airflow first, which can more efficiently remove the heat generated by the inverter 129, obtain the best cooling effect, and extend the life of the inverter 129. There is no need to design a separate branch air duct for the inverter 129, which simplifies the structure.

[0067] like Figure 2 and Figure 6 As shown, in some embodiments, the side shell 132 is provided with a first air inlet 130a corresponding to the cooling fan 173, and the bottom shell 1331 is provided with a second air inlet 130c corresponding to the cooling fan 173. Both the first air inlet 130a and the second air inlet 130c can allow air to enter, thereby reducing the noise of air intake. Moreover, the first air inlet 130a and the second air inlet 130c are located in different parts of the shell 130, which can reduce the risk of the air inlet being completely blocked.

[0068] like Figure 6 As shown, in some embodiments, the bottom shell 1331 is provided with a lock hole 133b, which can cooperate with a lock to lock the power generation device 100. The lock hole 133b is located at the bottom of the power generation device 100, which provides good concealment and is more aesthetically pleasing.

[0069] Furthermore, the bottom position is not easily noticed by potential thieves, increasing the difficulty of finding the lock. Thieves need to crouch, lie down, or even move machinery to reach the keyhole 133b, greatly increasing the difficulty of illegal operations and the risk of being discovered. Due to the tricky location of the keyhole 133b, conventional lock-picking tools such as crowbars and screwdrivers are difficult to effectively insert into the keyhole 133b or apply sufficient destructive force. Thieves need to adopt awkward postures (such as lying on the ground) to attempt to unlock or break the lock. Finding the location of the keyhole 133b and attempting to break or unlock it takes thieves more time, greatly increasing the risk of them lingering at the scene and making them easier to be detected by surveillance cameras, patrol personnel, or passersby.

[0070] In some embodiments, the engine 122 and generator 125 are mounted on the base shell 1331. The engine 122 and generator 125 are relatively heavy, which lowers the center of gravity of the power generation equipment 100, making the power generation equipment 100 more stable during operation and less prone to tipping over. Optionally, a shock absorber is provided at the bottom of the base shell 1331 to reduce vibrations transmitted to the ground.

[0071] like Figure 12 As shown, in some embodiments, the power generation device 100 further includes a soundproof cover 171, which covers the cylinder head 1222 of the engine 122. The cylinder head 1222 of the engine 122 contains a crankshaft, and noise generated by crankshaft rotation, piston movement, valve knocking, and ignition detonation easily escapes from the cylinder head 1222, making it one of the main noise sources. By providing a soundproof cover 171 to the cylinder head 1222 of the engine 122, the most significant high-frequency mechanical and combustion noises of the engine 122 can be precisely suppressed, achieving a good sound insulation effect. Additionally, the soundproof cover 171 also provides heat insulation, blocking radiant heat from the surface of the cylinder head 1222 and protecting the wiring harnesses and plastic parts around the cylinder head 1222. Optionally, due to the high temperature of the cylinder head 1222, the soundproof cover 171 can be made of a high-temperature resistant material.

[0072] In some embodiments, the power generation equipment 100 further includes a first sound insulation component, which is disposed between the sound insulation cover 171 and the cylinder head 1222 of the engine 122. The first sound insulation component abuts against both the inner surface of the sound insulation cover 171 and the cylinder head 1222 of the engine 122, that is, the sound insulation cover 171 presses against the cylinder head 1222 of the engine 122 through the first sound insulation component. The first sound insulation component is typically a flexible component, and can be, for example, sound insulation cotton, silicone pads, etc.

[0073] The addition of a first sound insulation component between the sound insulation cover 171 and the cylinder head 1222 can further improve the sound insulation effect, reduce the noise when the power generation equipment 100 is running, and the first sound insulation component can prevent the sound insulation cover 171 and the cylinder head 1222 from rigidly contacting and transmitting vibration.

[0074] In some embodiments, the power generation equipment 100 further includes a second sound insulation member, which is typically a flexible member and can be, for example, sound insulation cotton, silicone pads, etc.

[0075] In some embodiments, a second sound insulation member is disposed between the mating surfaces of the top shell 1311 and the side shell 132.

[0076] Understandably, the rigid top shell 1311 and side shell 132 are themselves good sound conductors. When the top shell 1311 and side shell 132 directly abut, vibrations and noise can be easily transmitted from one side to the other through the abutment. By providing a second sound insulation component between the mating surfaces of the top shell 1311 and side shell 132, the hard contact between the two shell components 130 can be physically isolated, significantly reducing the propagation of structural noise.

[0077] Secondly, even with precision machining, there are usually tiny gaps or unevenness between the mating surfaces of the top shell 1311 and the side shell 132, and these gaps are the main channels for noise leakage. The second sound insulation component is compressed after assembly, which can effectively fill these gaps and form an acoustic seal, thereby reducing the leakage of internal noise of the power generation equipment 100.

[0078] Finally, during equipment operation or handling, the outer casing may experience slight relative displacement due to vibration or external forces, potentially generating impact noise such as friction sounds at the mating surfaces. The second sound insulation component acts as a buffer, reducing or even eliminating noise generated by direct collisions or friction between rigid components.

[0079] In some embodiments, the second sound insulation member is disposed between the mating surfaces of the bottom shell 1331 and the side shell 132, and its effect can be referred to the above description, which will not be repeated here.

[0080] In some embodiments, the power generation equipment 100 further includes a third sound insulation element, which is typically a flexible element and may be, for example, sound insulation cotton, silicone pads, etc.

[0081] In some embodiments, a third sound insulation member is disposed between the mating surfaces of the first side plate 1323 and the second side plate 1324.

[0082] Understandably, the rigid first side plate 1323 and second side plate 1324 are themselves good sound conductors. When the first side plate 1323 and second side plate 1324 directly abut, vibration and noise can be easily transmitted from one side to the other through the abutment. By setting a third sound insulation component between the mating surfaces of the first side plate 1323 and second side plate 1324, the hard contact between the two housing components 130 can be physically isolated, significantly reducing the propagation of structural noise.

[0083] Secondly, even with precision machining, there are usually tiny gaps or unevenness between the mating surfaces of the first side plate 1323 and the second side plate 1324, and these gaps are the main channels for noise leakage. The third sound insulation component is compressed after assembly, which can effectively fill these gaps and form an acoustic seal, thereby reducing the leakage of internal noise of the power generation equipment 100.

[0084] Finally, during equipment operation or handling, the outer casing may experience slight relative displacement due to vibration or external forces, potentially generating impact noise such as friction sounds at the mating surfaces. The third sound insulation component acts as a buffer, reducing or even eliminating noise generated by direct collisions or friction between rigid components.

[0085] In some embodiments, the third sound insulation element is disposed between the mating surfaces of the second side plate 1324 and the third side plate 1325, and its effect can be referred to the above description, which will not be repeated here.

[0086] In some embodiments, the third sound insulation element is disposed between the mating surfaces of the third side plate 1325 and the fourth side plate 1326, and its effect can be referred to the above description, which will not be repeated here.

[0087] In some embodiments, the third sound insulation element is disposed between the mating surfaces of the fourth side plate 1326 and the first side plate 1323, and its effect can be referred to the above description, which will not be repeated here.

[0088] In some embodiments, the power generation equipment 100 further includes a fourth sound insulation member disposed between the mating surfaces of the housing 130 and the frame 110. The fourth sound insulation member is typically a flexible member, and can be, exemplarily, sound-absorbing cotton, silicone pads, etc.

[0089] Understandably, the rigid housing 130 and frame 110 are themselves good sound conductors. When the housing 130 and frame 110 are in direct contact, vibrations and noise can easily be transmitted from one side to the other through the contact area. By installing a fourth sound insulation component between the mating surfaces of the housing 130 and frame 110, the hard contact between the two housing 130 components can be physically isolated, significantly reducing the propagation of structural noise.

[0090] Secondly, even with precision machining, there are usually tiny gaps or unevenness between the mating surfaces of the housing 130 and the frame 110, and these gaps are the main channels for noise leakage. The fourth sound insulation component is compressed after assembly, which can effectively fill these gaps and form an acoustic seal, thereby reducing the leakage of internal noise of the power generation equipment 100.

[0091] Finally, during equipment operation or handling, the outer casing may experience slight relative displacement due to vibration or external forces, potentially generating impact noise such as friction sounds at the mating surfaces. The fourth sound insulation component acts as a buffer, reducing or even eliminating noise generated by direct collisions or friction between rigid components.

[0092] like Figure 13 and Figure 14As shown, in some embodiments, the power generation device 100 further includes a cooling fan 173 and a flow guide 172. The cooling fan 173 is disposed on one side of the power generation component 120, and the flow guide 172 is disposed on the other side of the power generation component 120. The housing 130 is provided with an exhaust port 130b, and the flow guide 172 is connected to the exhaust port 130b.

[0093] Cooling fan 173 draws in cool air from one side, which flows through power generation component 120, thereby cooling the component. Hot airflow is captured by shroud 172 and directed to exhaust port 130b. Shroud 172 guides the airflow, preventing hot air from spreading disorderly inside power generation device 100.

[0094] like Figure 15 As shown, in some embodiments, the fairing 172 includes a first cover 1721 and a second cover 1722, the second cover 1722 covering the power generation component 120, and the first cover 1721 disposed between the second cover 1722 and the power generation component 120.

[0095] The first cover 1721 has multiple exhaust holes 172a, and the first cover 1721 can communicate with each other through the exhaust holes 172a. The second cover 1722 is connected to an exhaust port 130b, and hot air can flow sequentially through the first cover 1721 and the second cover 1722 before being discharged from the exhaust port 130b. By providing multiple exhaust holes 172a, the airflow can be dispersed, thereby reducing airflow noise. Optionally, sound-insulating material can be filled between the first cover 1721 and the second cover 1722. The sound-insulating material can reduce the airflow velocity and further improve the sound insulation effect. The sound-insulating material is a breathable material, and the sound-insulating material can be, for example, sound-insulating cotton, fiberglass, etc.

[0096] like Figure 16 As shown, in some embodiments, the power generation device 100 further includes a cooling fan 173, which includes a fan blade 1731. The root of the fan blade 1731 protrudes in the direction of rotation R of the fan blade 1731, and the tip of the fan blade 1731 protrudes away from the direction of rotation R of the fan blade 1731, that is, the fan blade 1731 is roughly S-shaped.

[0097] The backward curve at the root of the 1731 impeller helps the airflow enter the impeller more smoothly, reducing impact losses and improving inlet efficiency. The forward curve at the tip can generate relatively high head and flow rate at the outlet, and the required speed may be lower and the noise lower when achieving the same performance (head and flow rate).

[0098] like Figure 13As shown, in some embodiments, the power generation device 100 includes a display panel 161, which is disposed on the top housing 1311. Optionally, the display panel 161 is an LCD screen, thereby providing relatively high display accuracy and rich display content.

[0099] Understandably, the generator 100 is typically placed on the ground, and users usually view it from a top-down angle. Therefore, the display panel 161 is positioned on the top casing 1311, allowing users to easily observe the information displayed on the panel. Users can clearly read data (such as voltage, frequency, current, operating hours, oil pressure, water temperature, fault codes, etc.) without bending over or squatting. Regardless of which side of the equipment the user stands on (front, side, or back), the display panel 161 is relatively easy to see. When the user walks to the equipment, they can immediately see the status of the top display screen without having to go around to a specific angle or adjust their posture, thus quickly determining whether the generator 125 is operating normally or has an alarm.

[0100] When the power generation equipment 100 is running, its sides and bottom areas are closer to high-temperature components (such as engine 122). Placing the display screen on top can keep the display panel 161 away from high-temperature components and extend the service life of the display panel 161.

[0101] Furthermore, the top-mounted display panel 161 effectively prevents direct contamination or corrosion from dust, dirt, and potential water splashes. This helps protect the display panel 161 and buttons 162, extending their lifespan and clarity.

[0102] Placing the display panel 161 on top keeps the sides clean and facilitates the layout of other functional components and the opening and closing of access doors.

[0103] In some embodiments, the power generation device 100 further includes a seal 152 disposed between the display panel 161 and the top shell 1311. Optionally, the top shell 1311 has a second opening corresponding to the display panel 161, allowing the display panel 161 to be visible through the top shell 1311. The seal 152 can fill the tiny gap between the edge of the display panel 161 and the edge of the second opening, thereby preventing dust, rainwater, and other small foreign objects from entering the interior of the power generation device 100, improving waterproof and dustproof performance. The seal 152 can be exemplarily a foam or silicone pad. The seal 152 is typically elastic and can absorb shocks and vibrations, thereby reducing the vibration transmitted to the display panel 161 and reducing the risk of the display panel 161 breaking or internal damage. The seal 152 also prevents the edge of the display panel 161 from directly contacting the top shell 1311, reducing local stress at the edge of the display panel 161.

[0104] In some embodiments, the power generation device 100 further includes a light-transmitting cover 163, which covers the top shell 1311 and corresponds to the display panel 161. The light-transmitting cover 163 and the top shell 1311 can be connected by welding, bonding, integral molding, or other methods. Optionally, the cover can close the second opening, thereby preventing dust, rainwater, and other small foreign objects from entering the interior of the power generation device 100, improving the waterproof and dustproof effect. The surface of the display panel 161 itself is usually soft and easily scratched. The light-transmitting cover 163 can resist scratches caused by sand, daily friction, etc., protecting the display panel 161 below. It can absorb and disperse impact energy when impacted, preventing the impact force from acting directly on the display panel 161 and reducing the risk of the display panel 161 breaking.
