Description

Technical Field

[0001] The invention relates to the technical field of fuel-fired generator sets, and more particularly to a portable fuel-fired generator set. Background Art

[0002] Fishing in winter is an important activity in the cold northern regions. Due to the thick ice, fishermen must rely on mechanical equipment to break ice and retract and release nets. These devices usually require a stable power supply to work properly. However, near remote lakes or rivers, the power grid coverage is limited and unstable. Traditional fixed fuel generator sets are large in size and heavy in weight, making it difficult to meet the requirements of flexible power supply. Therefore, portable fuel generator sets have become an indispensable power supply solution.

[0003] In recent years, in order to adapt to the special needs in extremely low temperature environments, fuel-fired generator sets developed for cold northern regions have adopted electric heating plugs or fuel preheating devices to ensure that the engine can start smoothly under extremely cold conditions; and diesel or gasoline suitable for low temperature environments are selected to ensure that the fuel will not solidify due to low temperature; and the coolant formula is improved to have a lower freezing point to ensure that the radiator will not be blocked by ice and snow, thereby maintaining the normal operating temperature of the engine.

[0004] Although the above-mentioned technological advances have significantly improved the performance of fuel-fired generator sets in cold northern regions, they still face some specific technical challenges in practical applications. For example, when moving a fuel-fired generator set on an icy surface, due to its large size and weight, multiple workers are required to carry it together, which not only reduces the human resources available on site, but also increases the difficulty of operation and safety risks. Especially on ice-covered ground, hidden sharp objects (such as ice or stones) may cause scratches on the generator set casing or damage to the bottom components. In addition, frequent handling may also affect the stability and service life of the equipment. Summary of the invention

[0019] (3) By setting up a sliding support mechanism, as the equipment moves forward, the extension plate at the rear end of the support plate and the side plates and support plates on it begin to contact the ice surface.

After the adjustment is completed, use the clamp again to lock the auxiliary plate to ensure that it will not shift during the sliding process. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] like Figure 1 , Figure 3 , Figure 4 , Figure 5 As shown, a bracket 672 fixedly connected to the second base plate 3 is provided on the upper side of the rotating rod No. 2 671 near the sleeve 675, a first limit block 674 fixedly connected to the rotating rod No. 2 671 is provided above the bracket 672, and a support frame No. 3 673 fixedly connected to the upper surface of the second base plate 3 is provided at the top of the rotating rod No. 2 671.

[0027] like Figure 4 , Figure 5 As shown, the side of the arc-shaped snow scraper cover 676 close to the sleeve 675 is a quarter semicircular arc plate, and the side away from the sleeve 675 is provided with an arc-shaped folding plate fixedly connected to the semicircular arc plate, and the arc-shaped folding plate and the semicircular arc plate together form an arc-shaped snow scraper cover 676 for scraping snow and clearing stones.

[0028] In order to solve the problem that the existing fuel generator set is difficult to carry due to its large size when moving on the ice surface, and the shell is easily scratched or the bottom component is damaged by sharp objects hidden in the ice and snow during the movement, the above technical solution is adopted to solve the problem. The above technical solution mainly consists of a snow-shoveling mechanism 6 and a driving mechanism 7. When the fuel generator set 1 moves on the ice surface, the user first fixes the second bottom plate 3 to the bottom of the first bottom plate 2 by threaded connection. Then, according to the actual situation, the telescopic push rod 5 is adjusted to a suitable height, and the self-locking universal wheel 4 is used to push the device to move. At the same time, the driving mechanism 7 is started, and its driving force is used to drive the rotating rod No. 1 61 to rotate, so that the rotating rod No. 1 61 drives the main gear 62 to rotate counterclockwise. And because the first snow scraping assembly 65 and the main gear 62 are driven by the same driving force, the first snow scraping assembly 65 and the main gear 62 are synchronously rotated counterclockwise, and the driven gear 66 meshing with the main gear 62 rotates in the opposite direction (i.e. clockwise). Specifically, when the driven gear 66 rotates in the opposite direction driven by the main gear 62, this enables the rotating rod No. 2 671 to rotate smoothly clockwise with the support of the support frame No. 3 673 and the bracket 672. At the same time, the first limit block 674 ensures that the rotating rod No. 2 671 remains stable during high-speed rotation to prevent displacement due to vibration or external force. As the rotating rod No. 2 671 rotates, the sleeve 675 together with the arc-shaped snow scraper cover 676 thereon will also move along an outward-expanding trajectory to clear the snow or potential sharp obstacles in front; and as the equipment moves forward, the snow-clearing mechanism 6 continues to operate to ensure that the path is always kept clean and flat, avoiding the accumulation of snow on the ice surface or sharp objects causing damage to the generator set. During the entire operation process, the overall weight of the equipment is significantly reduced by adopting a detachable first base plate 2 and second base plate 3 design, and the use of lightweight materials, making it easy to carry and transport. The telescopic push rod 5 allows the user to adjust the most comfortable operating height according to body height and personal habits; and the self-locking universal wheel 4 provides flexible direction control, making movement easier and more comfortable.

[0029] like Figure 1 , Figure 4 , Figure 5 As shown, the driving mechanism 7 includes a servo motor 71 fixedly connected to the middle of one side of the upper surface of the second base plate 3, the output end of the servo motor 71 is fixedly connected to a driving rod 72, the outer cylindrical surface of the driving rod 72 is fixedly connected to a first pulley 73, the end of the rotating rod No. 1 61 close to the supporting frame No. 1 63 is fixedly connected to a second pulley 74, and one side of the rotating rod No. 1 61 is provided with a third pulley 77 for driving the first snow scraper assembly 65 to rotate, the outer surfaces of the second pulley 74, the third pulley 77 and the first pulley 73 are jointly sleeved with a belt 75, and the driving rod 72 passes through the bottom of the second base plate 3 and is fixedly connected to a first bevel gear 76.

[0030] In order to ensure the normal movement of the fuel generator set 1 on the ice surface, when it is necessary to clean the snow and sharp objects on the ice surface, the servo motor 71 is started to rotate the driving rod 72, so that the first pulley 73 rotates accordingly, and the second pulley 74 and the third pulley 77 rotate under the transmission action of the belt 75. During the rotation of the second pulley 74, the rotating rod 61 fixedly connected thereto rotates accordingly, thereby driving the main gear 62 to rotate. During the rotation of the third pulley 77, the first snow scraper assembly 65 and the main gear 62 have the same rotation direction, and the second snow scraper assembly 67 is driven by the driven gear 66 meshing and rotating with the main gear 62. Therefore, the second snow scraper assembly 67 and the first snow scraper assembly 65 have opposite rotation directions, that is, under the opposite movement of the second snow scraper assembly 67 and the first snow scraper assembly 65, the arc-shaped snow scraper cover 676 is used to clear the snow or potential sharp obstacles in front along an outward-expanding trajectory; and as the equipment moves forward, the snow-clearing mechanism 6 continues to operate to ensure that the path is always kept clean and flat, avoiding any factors that may cause damage to the generator set.

[0031] like Figure 6 , Figure 7 As shown, a cleaning mechanism 8 for further cleaning the snow on the ice surface is provided at the bottom of the second bottom plate 3, and a sliding support mechanism 9 for moving the fuel generator set 1 is also provided at the bottom of the second bottom plate 3; wherein, the cleaning mechanism 8 includes a connecting plate 81 fixedly connected to one side of the bottom of the second bottom plate 3, a fixing seat 82 is fixedly connected to the bottom of the connecting plate 81, and a limiting seat 83 is fixedly connected to the other side of the bottom of the second bottom plate 3, a fixing rod 84 is fixedly connected between the limiting seat 83 and the fixing seat 82, and a movable seat 88 is slidably connected to the outer cylindrical surface of the fixing rod 84, a threaded rod 85 is threadedly connected to the middle of the inner part of the movable seat 88, and the threaded rod 85 passes through the fixing seat 82 and is fixedly connected to a second bevel gear 86, and the second bevel gear 86 is meshed with the first bevel gear 76 to drive the threaded rod 85 to rotate.

[0032] like Figure 6 , Figure 7 As shown, second limit blocks 87 fixedly connected to the threaded rod 85 are provided on both sides of the outer surface of the fixed seat 82, support plates 89 are hinged at both ends of the fixed seat 82, an adjusting rod 891 is hinged between the support plate 89 and the movable seat 88, a baffle 893 is fixedly connected to the upper surface of the support plate 89, and a snow scraper 892 is fixedly connected to the bottom of the support plate 89.

[0033] When the entire fuel generator set 1 needs to be moved on the ice surface and snow is cleared, the user first installs the second base plate 3 on the first base plate 2 by threaded connection, then adjusts the telescopic push rod 5 to a suitable height according to the actual situation, and uses the self-locking universal wheel 4 to push the device to move. At the same time, the drive mechanism 7 is started, which drives the rotating rod No. 1 61 to make the main gear 62 rotate counterclockwise, thereby driving the snow-clearing mechanism 6 to work to clear the snow and obstacles in front. After the servo motor 71 is started, the driving rod 72 at its output end starts to rotate. The first pulley 73 on the driving rod 72 synchronously drives the second pulley 74 and the third pulley 77 through the belt 75, thereby making the rotating rod No. 1 61 and the snow-clearing assembly thereon operate. Because the driving rod 72 passes through the bottom of the second base plate 3, and a first bevel gear 76 is fixedly connected to its end. The first bevel gear 76 meshes with the second bevel gear 86 in the cleaning mechanism 8, thereby transmitting power to the threaded rod 85. As the first bevel gear 76 rotates, the second bevel gear 86 rotates accordingly, so that the threaded rod 85 fixedly connected thereto rotates clockwise in the fixed seat 82 and the limit seat 83, and the second limit block 87 ensures the stability of the threaded rod 85 during the rotation process to prevent the angle from shifting. The rotation of the threaded rod 85 causes the movable seat 88 to move forward along the fixed rod 84. During this process, the adjustment rod 891 is stretched outward, causing the support plate 89 to expand outward. In this way, the snow scraper 892 and the baffle 893 fixedly connected to the support plate 89 also move outward synchronously. In this way, the snow scraper 892 can perform a secondary cleaning of the snow and sharp objects remaining on the ice surface to ensure that the path is unobstructed; at the same time, the baffle 893 can effectively prevent the scraped snow from entering the bottom area of ​​the device to protect the internal components from damage. In the above-mentioned operating procedures, the snow-clearing mechanism 6 and the cleaning mechanism 8 work together to not only clear the snow and obstacles in front, but also further clean the ice surface, reduce the risk of damage to the bottom components of the generator set, and protect the safe operation of the equipment; and by setting up the cleaning mechanism 8, it is ensured that an efficient working state can be maintained even under complex conditions, avoiding the influence of obstacles such as snow and stones on the equipment, and improving the overall performance.

[0034] like Figure 6 , Figure 7 , Figure 8 As shown, the sliding support mechanism 9 includes an extension plate 91 fixedly connected to the rear end of the support plate 89, and side plates 92 are fixedly connected to both sides of the bottom of the extension plate 91, and a support plate 93 is fixedly connected to the bottom of the side plate 92, and the side plate 92 and the support plate 93 form an angle of 45 degrees to improve stability.

[0035] like Figure 6 , Figure 7 , Figure 8As shown, limiting grooves 94 are provided on both sides of the interior of the support plate 93, and limiting rods 95 are fixedly connected to both sides of the interior of the limiting grooves 94. The outer circular surface of the limiting rod 95 is slidably connected to an auxiliary plate 96, and one end of the limiting rod 95 is provided with a clamping sleeve 97 for locking the auxiliary plate 96.

[0036] The user first securely installs the second base plate 3 on the first base plate 2 through a threaded connection, and then adjusts the height of the telescopic push rod 5 according to personal needs to ensure that the operator can maintain a comfortable posture when pushing the device. At this time, the sliding support mechanism 9 is already in a standby state, ready to move with the device. When everything is ready, start the driving mechanism 7, which will drive the rotating rod No. 1 61 to make the main gear 62 rotate counterclockwise, thereby driving the snow-clearing mechanism 6 to work and clear the snow and obstacles in front. At the same time, the snow scraper 892 in the cleaning mechanism 8 further cleans the ice surface, and the baffle 893 prevents the snow from entering the bottom area of ​​the device. As the device moves forward, the extension plate 91 at the rear end of the support plate 89 and the side plate 92 and the support plate 93 thereon begin to contact the ice surface. Since the side plate 92 and the support plate 93 are at an angle of 45 degrees, this structure not only improves the overall stability, but also increases the contact area with the ice surface, reduces the pressure per unit area, and prevents the device from sinking into a softer snow layer. Under the action of the limiting rod 95, the auxiliary plate 96 can slide in the limiting groove 94, and according to actual needs, loosen the sleeve 97 and adjust the position of the auxiliary plate 96 to expand the contact area with the ice surface. After the adjustment is completed, use the sleeve 97 again to lock the auxiliary plate 96 to ensure that it will not shift during the sliding process.

[0037] like Figure 1 , Figure 2 , Figure 3 As shown, a heat preservation mechanism 10 is arranged on the outside of the fuel-fired generator set 1, and the heat preservation mechanism 10 includes a shielding plate 103 hinged on both sides of the outer surface of the second bottom plate 3, a cover plate 104 is hinged on the top of the shielding plate 103, and a locking seat 105 is fixedly connected to one side of the upper surface of the cover plate 104, and heat preservation plates 106 are fixedly connected to both sides of the outer surface of the shielding plate 103, and the shielding plate 103, the cover plate 104, and the heat preservation plate 106 cooperate to form a cavity for the heat preservation operation of the fuel-fired generator set 1.

[0038] like Figure 1 , Figure 2 , Figure 3 As shown, the heat preservation mechanism 10 further includes a heat exchanger 101 which is close to the servo motor 71 and fixedly connected to one side of the upper surface of the first bottom plate 2 , and the output end of the heat exchanger 101 is fixedly connected to a delivery pipe 102 .

[0039] When the fuel generator set 1 moves on the ice surface, the driving mechanism 7 drives the snow-clearing mechanism 6 and the cleaning mechanism 8 to clean the snow and sharp objects on the ice surface through the action of belt transmission and gear transmission. In this process, the driving mechanism 7 will generate a certain amount of heat. The heat generated by the driving mechanism 7 is recovered by the heat exchanger 101, and then the heat is transferred to the baffle plate 103, the insulation plate 106, and the baffle plate 103 and the cover plate 104 to form a cavity together through the conveying pipe 102, so as to reduce heat loss and maintain the normal operation of the equipment in a low temperature environment. In the above operation process, the insulation mechanism 10 not only provides a good insulation effect, but also protects the fuel generator set 1 from the influence of the external environment and prolongs the service life of the equipment. At the same time, the flip cover structure of the baffle plate 103 and the cover plate 104 facilitates the user to open and close the insulation mechanism 10, which is convenient for maintenance and repair.

[0040] When the present invention is used, the user first securely mounts the second base plate 3 to the first base plate 2 by threaded connection, and adjusts the height of the telescopic push rod 5 according to personal needs to ensure that the operator can maintain a comfortable posture when pushing the device. At this time, the sliding support mechanism 9 is in a standby state and is ready to move with the device. When everything is ready, the driving mechanism 7 is started, which will drive the rotating rod No. 1 61 to make the main gear 62 rotate counterclockwise, thereby driving the snow-clearing mechanism 6 to work and clear the snow and obstacles in front. At the same time, after the servo motor 71 is started, the driving rod 72 at its output end starts to rotate. The first pulley 73 on the driving rod 72 synchronously drives the second pulley 74 and the third pulley 77 through the belt 75, thereby making the rotating rod No. 1 61 and the snow-clearing assembly thereon operate. Since the driving rod 72 passes through the bottom of the second base plate 3 and is fixedly connected to the first bevel gear 76 at its end, the first bevel gear 76 is meshed with the second bevel gear 86 in the cleaning mechanism 8, thereby transmitting power to the threaded rod 85. As the first bevel gear 76 rotates, the second bevel gear 86 rotates accordingly, so that the threaded rod 85 fixedly connected thereto rotates clockwise in the fixed seat 82 and the limit seat 83, and the second limit block 87 ensures the stability of the threaded rod 85 during the rotation process to prevent the angle from shifting. The rotation of the threaded rod 85 causes the movable seat 88 to move forward along the fixed rod 84. During this process, the adjustment rod 891 is stretched outward, causing the support plate 89 to expand outward. In this way, the snow scraper 892 and the baffle 893 fixedly connected to the support plate 89 also move outward synchronously, and the snow scraper 892 is used to perform a secondary cleaning of the snow and sharp objects remaining on the ice surface to ensure that the path is unobstructed; at the same time, the baffle 893 can effectively prevent the scraped snow from entering the bottom area of ​​the device to protect the internal components from damage. As the device moves forward, the extension plate 91 at the rear end of the support plate 89 and the side plate 92 and the support plate 93 thereon begin to contact the ice surface. Since the side plate 92 and the support plate 93 are at an angle of 45 degrees, this structure not only improves the overall stability, but also increases the contact area with the ice surface, reduces the pressure per unit area, and prevents the equipment from sinking into the softer snow layer. Under the action of the limit rod 95, the auxiliary plate 96 can slide in the limit groove 94, and according to the actual situation, loosen the clamping sleeve 97 and adjust the position of the auxiliary plate 96 to expand the contact area with the ice surface. After the adjustment is completed, the clamping sleeve 97 is used again to lock the auxiliary plate 96 to ensure that it will not deviate during the sliding process. When the fuel generator set 1 moves on the ice surface, the driving mechanism 7 drives the snow-clearing mechanism 6 and the cleaning mechanism 8 to clean the snow and sharp objects on the ice surface through the action of belt transmission and gear transmission. In this process, the driving mechanism 7 will generate a certain amount of heat. The heat is recovered by the heat exchanger 101 and transferred to the baffle plate 103, the insulation plate 106 and the cavity formed by the baffle plate 103 and the cover plate 104 through the delivery pipe 102, thereby reducing heat loss and maintaining the normal operation of the equipment in a low temperature environment.The heat preservation mechanism 10 not only provides a good heat preservation effect, but also protects the fuel-fired generator set 1 from the influence of the external environment, thereby extending the service life of the equipment.
