Description

Technical Field

[0001] This invention relates to the field of generator technology, specifically to a portable, low-energy-consumption, ultra-quiet generator set. Background Technology

[0002] As a crucial energy conversion device, the core function of a generator set is to efficiently convert mechanical energy or other forms of energy into electrical energy, providing indispensable power support for modern society. This equipment has an extremely wide range of applications, not only penetrating the core of the power system but also widely permeating many key areas such as industrial production, construction, and emergency backup, becoming an important infrastructure ensuring the normal operation of society.

[0003] In existing technologies, to meet flexible power needs in different scenarios, some generator sets have undergone innovative design optimizations. Specifically, these generator sets achieve convenient movement and transportation by directly installing omnidirectional casters on their lower end faces or by securely fixing them to trailers or chassis. This design allows the generator sets to easily handle temporary power needs, such as field operations and emergency rescue, and demonstrates unique advantages, especially in complex environments such as construction sites, large event venues, and natural disaster relief. Therefore, these types of generator sets are also figuratively called mobile generator sets.

[0004] For example, patent publication number CN 119802423 A discloses an intelligent adjustment device and method for a generator set, including: a mounting frame with four casters, a generator set body mounted on the bottom inner wall of the mounting frame, and a support and protection mechanism mounted on the mounting frame. The support and protection mechanism includes two sets of rotating components, four movable frames, four sets of telescopic components, and two support and protection plates. Each set of rotating components is symmetrically arranged on both sides of the outer wall of the mounting frame, each pair of movable frames is located on the rotating components, and each set of telescopic components is located on the movable frames. This intelligent adjustment device and method for a generator set, by installing casters on the mounting frame, facilitates the manual transportation of the generator set body, especially in scenarios requiring frequent movement or position adjustments, improving the flexibility of the generator set body's movement. Furthermore, during the movement of the generator set body, the support and protection mechanism, in conjunction with the casters, provides protection against external objects colliding with the generator set body, ensuring its normal operation.

[0005] However, while this design improves the mobility of generator sets to some extent, it also reveals many shortcomings in practical applications. After the generator set is moved to its intended use location via rollers, each roller needs to be manually secured one by one, a process that is not only cumbersome but also inefficient. More importantly, due to the typically heavy weight of generator sets, the rollers experience significantly accelerated material fatigue under prolonged pressure, thus affecting their lifespan. Furthermore, roller wear leads to increased energy consumption and noise during generator operation, increasing operating costs and negatively impacting the surrounding environment. Therefore, existing mobile generator sets still have significant shortcomings in terms of energy consumption, noise, and lifespan, failing to meet the current market's urgent demand for efficient, environmentally friendly, and quiet power generation equipment.

[0006] To address the aforementioned issues, we propose an innovative solution—a portable, low-energy, ultra-quiet generator set. This solution aims to comprehensively improve the generator set's portability, energy consumption control, and noise reduction through optimized design and technological innovation. Summary of the Invention

[0007] The purpose of this invention is to provide a portable, low-energy-consumption, ultra-quiet generator set, which solves the problems mentioned in the background art. After moving such a portable generator set to the application scenario using rollers, it is necessary to manually fix each roller one by one. This process is cumbersome. Furthermore, since the generator set is generally heavy, when the rollers bear the weight of the generator set for a long time, it will accelerate the material fatigue rate, thereby affecting its service life, energy consumption during operation, and noise levels.

[0008] To achieve the above objectives, the present invention provides the following technical solution: a portable, low-energy, ultra-quiet generator set, comprising a generator assembly, wherein a self-locking lifting roller base is fixed to the lower end face of the generator assembly, the self-locking lifting roller base comprising a self-locking lifting mechanism, a square plate and four universal rollers, wherein the four universal rollers are respectively fixed to the four corners of the lower end face of the square plate, and the self-locking lifting mechanism is capable of moving the square plate up and down arbitrarily and can fix the downwardly moving square plate in the current position; The generator assembly is provided with a high sound insulation waste heat power generation shell on its outside. The high sound insulation waste heat power generation shell includes a U-shaped frame and multiple heat absorption tubes. The multiple heat absorption tubes are fixed in a U-shape to the lower end face of the U-shaped frame. A small waste heat generator is provided above the middle position of the multiple heat absorption tubes, and each heat absorption tube is connected to the small waste heat generator through a heat transfer pipe.

[0009] The self-locking lifting mechanism includes a bottom housing. A stepper motor is fixedly installed above the middle position inside the bottom housing. The output shaft of the stepper motor is connected to a transmission shaft through a coupling. A threaded lifting rod is fixedly connected to the lower end face of the transmission shaft. The square plate is installed on the outer surface of the threaded lifting rod through a threaded structure.

[0010] The square plate has a square groove located inside the bottom shell on its outer side. The outer surface of the square plate fits against the inner wall of the square groove, and the square plate and the square groove are slidably connected.

[0011] A first bevel gear is fixedly sleeved on one side of the outer surface of the transmission shaft. A second bevel gear is meshed with both sides of the outer surface of the first bevel gear. A threaded rod is connected to the shaft of the second bevel gear. An internal threaded sleeve is installed on one side of the outer surface of the threaded rod through a threaded structure. An L-shaped rod is fixedly connected to one side of the upper end face of the internal threaded sleeve.

[0012] The ends of the first and second L-shaped rods from left to right, which are close to the transmission shaft, are slidably connected to the outer shell of the bottom housing. An arc-shaped fixing plate is fixed to the surface of the L-shaped rod facing the transmission shaft, and a rubber sleeve fixedly fitted on the outer surface of the transmission shaft is provided between the two arc-shaped fixing plates.

[0013] An insulating inner partition is fixed to the outside of the U-shaped frame. A cable interface is fixedly installed on one side of the upper end face of the insulating inner partition, and the small waste heat generator and the generator assembly are electrically connected to the cable interface.

[0014] The outer side of the inner insulating layer is fixedly provided with a polyester fiber outer sound-absorbing layer, the inner side of the polyester fiber outer sound-absorbing layer is provided with a middle rock wool insulating layer, and the inner side of the middle rock wool insulating layer is provided with an inner gypsum board sound-insulating layer.

[0015] The high sound insulation waste heat power generation shell also includes a generator set shell. A slide rail is provided on both sides of the inner wall of the generator set shell. A slider is slidably installed on the lower side inside the slide rail, and the surface of the slider facing the inner partition is fixed to the inner partition.

[0016] A control panel is fixedly installed on one side of the outer surface of the generator set housing. A door mounting groove for the switch is located on one side of the control panel on the outer surface of the generator set housing, and a door is installed inside the door mounting groove via a rotating shaft.

[0017] The stepper motor is provided with a protective cover plate located on the upper surface of the bottom housing, and the bottom housing and the protective cover plate are fixed together by screws.

[0018] Compared with the prior art, the beneficial effects of the present invention are: 1. This invention, when the device needs to be moved, uses a self-locking lifting mechanism to simultaneously move four omnidirectional rollers downwards. When the lower surface of the omnidirectional rollers contacts the ground but the rollers are still being pushed downwards, the entire device will be lifted. The device can then be pushed using the lifted omnidirectional rollers. After the device is pushed to the usage position, the self-locking lifting mechanism retracts the omnidirectional rollers to their original positions. During the retraction of the omnidirectional rollers, the lower surface of the bottom shell will contact the ground. Once the omnidirectional rollers are no longer in contact with the ground, the entire device can no longer be moved by the omnidirectional rollers. This technical solution eliminates the need to fix multiple omnidirectional rollers one by one to enhance the overall stability of the device, thereby increasing the convenience of the device. 2. The present invention moves the entire device by moving the universal rollers downward through a self-locking lifting mechanism only when the entire device needs to be moved. The universal rollers only bear the weight of the device during the movement process. Through the above technical solution, the total time that the universal rollers bear the weight of the device is reduced, the fatigue rate is reduced, and the service life of the universal rollers is increased. 3. The present invention uses a heat-absorbing pipe in the high-sound-insulating waste heat power generation shell to absorb the heat generated by the generator assembly when it is working and to transfer the heat to a small waste heat generator. The small waste heat generator can generate power through the heat absorbed by the heat-absorbing pipe. The above technical solution can absorb the heat generated by the generator assembly when it is working to produce power, thereby reducing the overall energy consumption of the equipment.

[0021] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0022] Please see Figures 1 to 6 The present invention provides an embodiment of a portable, low-energy, ultra-quiet generator set, comprising a generator assembly 3. The lower end face of the generator assembly 3 is fixed with a self-locking lifting roller base 2. The self-locking lifting roller base 2 consists of three core parts: a self-locking lifting mechanism, a square plate 204, and four universal rollers 206. The components work together to achieve the flexible and stable operation of the base. The four universal rollers 206 are respectively fixed to the four corners of the lower end face of the square plate 204. The self-locking lifting mechanism can move the square plate 204 up and down arbitrarily and can fix the downwardly moving square plate 204 in the current position.

[0023] The self-locking lifting mechanism includes a bottom housing 201. A stepper motor 202 is fixedly installed above the center of the bottom housing 201. The output shaft of the stepper motor 202 is connected to a transmission shaft 203 via a coupling. A threaded lifting rod 214 is fixedly connected to the lower end face of the transmission shaft 203, and a square plate 204 is threaded onto the outer surface of the threaded lifting rod 214. When the equipment needs to be moved, the stepper motor 202 is started first. The stepper motor 202 drives the connected transmission shaft 203 and the threaded lifting rod 214 fixed to the lower end face of the transmission shaft 203 to rotate together. This is the core power and control unit of the entire base, possessing highly flexible and precise adjustment capabilities. Through a complex internal mechanical transmission structure, it can generate smooth and continuous lifting power. This power can be precisely transmitted to the square plate 204, enabling arbitrary adjustment of the height of the square plate 204. Whether it requires slight adjustments to adapt to different working heights or larger lifting operations, the self-locking lifting mechanism can easily handle the task.

[0024] The outer side of the square plate 204 is provided with a square groove 205 located inside the bottom outer shell 201. The outer surface of the square plate 204 is in contact with the inner wall of the square groove 205, and the square plate 204 and the square groove 205 are slidably connected. Since the outer surface of the square plate 204, which is connected to the threaded lifting rod 214 through a threaded structure, is in contact with the inner wall of the square groove 205, the square plate 204 cannot rotate on its own, thus forming a self-locking mechanism. Specifically, when the square plate 204 reaches the desired position during descent, the mechanism can quickly and reliably fix the square plate 204 in its current position. This function is achieved through an internal self-locking device. When the square plate 204 is descending, the self-locking device is in the unlocked state, not affecting its normal descent; and when the descent operation stops, the self-locking device immediately and automatically locks, preventing the square plate 204 from accidentally sliding down due to external forces (such as the weight of the equipment itself, external vibrations, etc.), thus ensuring the stability and safety of the entire device during operation. Furthermore, the square plate 204, as a crucial load-bearing component of the self-locking lifting roller base 2, plays a key supporting role. It is made of high-strength, high-rigidity materials, such as high-quality steel or high-strength aluminum alloy, to ensure it can withstand the weight of the equipment installed above and various dynamic loads generated during movement. The square plate 204 has a large planar area, providing a stable and spacious platform for the installation of the equipment above. Whether it is large machinery, precision instruments, or other types of mobile work devices, they can all be securely installed on the square plate 204. Furthermore, the square plate 204 is tightly connected to the self-locking lifting mechanism. Through specific connection structures, such as bolt connections or welding, the lifting power generated by the self-locking lifting mechanism is accurately transmitted to itself, enabling flexible adjustment of its height. Simultaneously, the lower end face of the square plate 204 is carefully designed and machined to provide a stable mounting position for the four omnidirectional casters 206, ensuring that the casters 206 can be reliably fixed to the base, providing strong support for the movement of the entire device.

[0025] When the threaded lifting rod 214 rotates, the square plate 204, which is threaded to it but cannot rotate on its own, will move up and down under the drive of the threaded structure. As the square plate 204 moves downwards, the distance between the universal roller 206, fixed to the lower end of the square plate 204, and the ground will gradually decrease. When the lower end of the universal roller 206 contacts the ground but is still being pushed downwards, the entire device will be lifted. Then, the device is pushed forward by the universal roller 206 that lifts it. Once the device is pushed to the usage location, the universal rollers 206 are retracted to their original positions via a self-locking lifting mechanism. During the retraction of the universal rollers 206, the lower end of the bottom housing 201 will contact the ground. Once the universal rollers 206 are no longer in contact with the ground, the device as a whole can no longer move via the universal rollers 206. With the above technical solution, it is no longer necessary to fix multiple universal rollers 206 one by one to enhance the overall stability of the device, thereby increasing the convenience of the device. Four omnidirectional casters 206 are fixed to the four corners of the lower surface of the square plate 204, and are key components for the flexible movement of the self-locking lifting caster base 2. Each omnidirectional caster 206 has 360-degree omnidirectional rotation, allowing the base to freely change its direction of movement on a horizontal plane without the need for cumbersome steering operations. Whether turning or making a U-turn in narrow spaces, or navigating complex terrain, the omnidirectional casters 206 can handle it with ease, greatly improving the base's mobility and ease of operation. Furthermore, the omnidirectional casters 206 are typically made of highly wear-resistant, low-friction materials, such as rubber or polyurethane, to reduce frictional resistance with the ground, making the base move more easily and smoothly. High-quality bearings are also installed inside the casters to ensure smooth operation, low noise, and a long service life during rotation. In addition, some omnidirectional casters 206 are equipped with a braking device. When the base reaches the designated position, the brake device can be operated to lock the casters, preventing accidental movement of the base during operation and further enhancing the stability and safety of the device.

[0026] In the above technical solution, the universal roller 206 is moved downward by the self-locking lifting mechanism to move the entire device only when the device needs to be moved. The universal roller 206 only bears the weight of the device during the movement of the device. This structure can reduce the total time that the universal roller 206 bears the weight of the device, reduce its fatigue rate, and increase the service life of the universal roller 206.

[0027] A first bevel gear 208 is fixedly sleeved on one side of the outer surface of the transmission shaft 203. A second bevel gear 209 is meshed with both sides of the outer surface of the first bevel gear 208. A threaded rod 210 is connected to the shaft of the second bevel gear 209. An internal threaded sleeve 211 is installed on one side of the outer surface of the threaded rod 210 through a threaded structure. An L-shaped rod 212 is fixedly connected to one side of the upper end face of the internal threaded sleeve 211. The ends of the first and second L-shaped rods 212 near the transmission shaft 203 are slidably connected to the outer shell of the bottom outer shell 201. An arc is fixed on the surface of the L-shaped rod 212 facing the transmission shaft 203. A square plate 204 fixed to the outer surface of the transmission shaft 203 and a rubber sleeve 207 fixedly sleeved on the outer surface of the transmission shaft 203 are provided between the two arc-shaped fixed plates 213. During the rotation of the transmission shaft 203, the square plate 204 fixed to the outer surface of the transmission shaft 203 and the two second bevel gears 209 meshing with the first bevel gear 208 will rotate together. The rotating second bevel gears 209 can drive the threaded rod 210 connected to its shaft to rotate synchronously. Since the upper end face of the inner threaded sleeve 211 installed on the outer surface of the second bevel gear 209 through the threaded structure is fixed between the inner threaded sleeve 211 and the L-shaped rod 212, the inner threaded sleeve 211 itself cannot rotate. When the threaded rod 210 rotates, the internal threaded sleeve 211, which is threaded to it but cannot rotate on its own, will move inward or outward under the drive of the threaded structure. When the internal threaded sleeve 211 moves inward, the arc-shaped fixing plate 213, which is connected to it through the L-shaped rod 212, will also move inward. When the arc-shaped fixing plate 213 comes into contact with the rubber sleeve 207 fixed on the outer surface of the transmission shaft 203, the transmission shaft 203 can be fixed. Through the above technical solution, the transmission shaft 203 used for transmission can be fixed when the entire equipment is lifted, thereby preventing the universal roller 206 from entering the equipment under the action of external force when the equipment is pushed by the universal roller 206. This structure can increase the overall stability of the equipment.

[0028] The generator assembly 3 is equipped with a high-sound-insulating waste heat power generation shell on its outer side. The high-sound-insulating waste heat power generation shell includes a U-shaped frame 5 and multiple heat-absorbing pipes 6. The multiple heat-absorbing pipes 6 are fixed in a U-shape to the lower end face of the U-shaped frame 5. A small waste heat generator 7 is provided above the middle position of the multiple heat-absorbing pipes 6, and each heat-absorbing pipe 6 is connected to the small waste heat generator 7 through a heat transfer pipe 14. An insulating inner partition 4 is fixed to the outer side of the U-shaped frame 5. A cable interface 8 is fixedly installed on one side of the upper end face of the insulating inner partition 4, and the small waste heat generator 7 and the generator assembly 3 are electrically connected to the cable interface 8. When the generator assembly 3 needs to be used, a cable connector is connected to the cable interface 8, and then the generator assembly 3 is started. The generator assembly 3 can transmit the power it generates to the cable interface 8. The heat generated by the generator assembly 3 during operation will be absorbed by multiple heat absorption pipes 6 fixed to the lower end face of the U-shaped frame 5. The heat absorbed by the heat absorption pipes 6 will be transferred to the small waste heat generator 7 through the heat transfer pipe 14. The small waste heat generator 7 can generate electricity through the waste heat transferred from the heat absorption pipes 6 and transmit it to the cable interface 8 for use. The above technical solution can absorb the heat generated by the generator assembly 3 during operation to produce power, thereby reducing the overall energy consumption of the equipment.

[0029] A polyester fiber outer sound-absorbing layer 13 is fixedly provided on the outer side of the inner partition 4. A middle rock wool insulation layer 12 is provided on the inner side of the polyester fiber outer sound-absorbing layer 13. An inner gypsum board sound insulation layer 11 is provided on the inner side of the middle rock wool insulation layer 12. The polyester fiber outer sound-absorbing layer 13, the middle rock wool insulation layer 12 and the inner gypsum board sound insulation layer 11 located inside the outer shell of the inner partition 4 can absorb the noise generated during the operation of the equipment.

[0030] The high-sound-insulation waste heat power generation shell also includes a generator set shell 1. A slide rail 9 is provided on both sides of the inner wall of the generator set shell 1. A slider 10 is slidably installed on the lower side inside the slide rail 9, and the slider 10 is fixed to the inner partition 4 facing the inner partition 4. A control panel is fixedly installed on one side of the outer surface of the generator set shell 1. A door mounting groove is provided on one side of the control panel, and a door is installed inside the door mounting groove through a rotating shaft. The entire equipment can be controlled through the control panel. When it is necessary to open the switch door to add the fuel required for the generator assembly 3, the slider 10 is moved upward to isolate the entire inner partition 4. When the inner partition 4 is completely separated from the outside of the generator assembly 3 and the obstruction of the inner partition 4 is removed, the switch door can be opened directly to expose the entire generator assembly 3 to the outside.

[0031] A protective cover plate is provided above the stepper motor 202 on the upper surface of the bottom housing 201, and the bottom housing 201 and the protective cover plate are fixed together by screws; the protective cover plate can seal and protect the stepper motor 202.

[0032] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention.
