Description

Technical Field

[0001] This invention relates to the field of generator technology, specifically to a generator set with adjustable output power. Background Technology

[0002] In the manufacturing of power transmission, distribution, and control equipment, including ground-based AC and underground AC charging piles, a stable and reliable power supply is a core prerequisite for ensuring the orderly progress of production, which is closely linked to the stable operation of generator sets. Existing generator sets used in this field typically employ a simple combination of air and water cooling. When the generator set's output power is low, the air cooling system can usually meet the equipment's heat dissipation needs and maintain the basic power supply during the manufacturing process. However, as production load increases and the generator set's output power rises, air cooling alone is insufficient to achieve the desired cooling effect. In this case, a water cooling system is needed to enhance heat dissipation. After prolonged use, scale easily accumulates on the inner walls of the water cooling pipes. The presence of scale significantly reduces heat exchange efficiency, resulting in a substantial decrease in cooling effect and consequently affecting the generator set's output stability. Furthermore, existing water cooling systems rely heavily on manual disassembly or chemical cleaning for scale removal. In the context of power transmission, distribution, and control equipment manufacturing, this method is not only cumbersome and costly to maintain, but also requires shutdown, severely impacting the continuous operation of the production line and hindering the assurance of production continuity and the reliability of emergency power supply. Summary of the Invention

[0003] The purpose of this invention is to provide a generator set with adjustable output power to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a generator set with adjustable output power, comprising a generator housing and a generator set disposed therein, and further comprising:

[0005] The first connecting pipe is fixed inside the generator housing and connects to multiple water-cooling pipes;

[0006] The second connecting pipe is connected to the upper end of multiple water-cooling pipes;

[0007] The adjustment mechanism, located on the second connecting pipe, includes multiple movable sealing discs that can move vertically and an alternating component that drives them to move alternately.

[0008] The cleaning mechanism, located inside the water-cooling pipe, includes multiple rotating scrapers and a rotating assembly that drives them to rotate;

[0009] When the alternating component drives a portion of the movable sealing discs to move downwards to seal the upper end of the corresponding water-cooling pipe, while another portion of the movable sealing discs moves upwards to open the corresponding water-cooling pipe, the rotating component drives the rotating scraper to rotate inside multiple water-cooling pipes to remove scale. The water flow rate inside the unsealed water-cooling pipes increases, flushing and discharging the scraped scale.

[0010] Preferably, the alternating component includes a connecting rotating rod rotatably disposed inside the second connecting pipe, and two sets of pushing protrusions are fixedly installed on the connecting rotating rod, with the two sets of pushing protrusions located on both sides of the connecting rotating rod respectively.

[0011] Preferably, each set of connecting rotating rods consists of multiple rods, and the two sets of connecting rotating rods alternately contact the corresponding movable sealing disc and drive it to move downward to seal the upper end of the corresponding water-cooling pipe.

[0012] When the connecting rotating rod rotates, one set of pushing protrusions pushes the corresponding movable sealing plate downward to seal the water cooling pipe, while another set of pushing protrusions disengages from the corresponding movable sealing plate, causing the movable sealing plate to move upward to open the water cooling pipe.

[0013] Preferably, a connecting support plate is fixed on the movable sealing disc, and a fixed vertical slide rod slides inside the connecting support plate. A second connecting spring is sleeved on the fixed vertical slide rod, with one end of the second connecting spring connected to the inner wall of the second connecting pipe and the other end connected to the connecting support plate.

[0014] Preferably, the rotating assembly includes a movable pressure plate fixedly installed at the lower end of the movable sealing disc and a sliding support plate slidably connected inside the water cooling pipe. A push connecting plate is hinged to the lower end of the sliding support plate, and a sliding toothed plate is hinged to the lower end of the push connecting plate. A fixed horizontal plate slides inside the sliding toothed plate.

[0015] Preferably, the fixed horizontal plate is fixedly installed inside the water-cooling pipe, and a first connecting spring is sleeved on the fixed horizontal plate. One end of the first connecting spring is connected to a sliding toothed plate, and the other end is connected to the inner wall of the water-cooling pipe. A first connecting gear is meshed on the sliding toothed plate, and a rotating connecting rod is fixedly installed at the lower end of the first connecting gear.

[0016] Preferably, the rotating link is rotatably connected to a fixed support frame, the fixed support frame is fixedly installed on the water cooling pipe, and a rotating scraper is fixedly installed on the rotating link, with one end of the rotating scraper contacting the inner wall of the water cooling pipe.

[0017] Preferably, when the movable sealing disc moves downward, the movable pressure plate pushes the sliding support plate downward, causing the sliding toothed plate to slide along the fixed horizontal plate and compress the first connecting spring. The sliding toothed plate drives the first connecting gear to rotate, thereby driving the rotating scraper to rotate in the forward direction to scrape away the scale.

[0018] Preferably, when the movable sealing disc moves upward, the first connecting spring rebounds and pushes the sliding toothed plate to reset, driving the rotating scraper to rotate in the opposite direction to scrape off the scale.

[0019] Preferably, the generator housing has a ventilation window on its side wall, and a fixed fan is installed inside the generator housing, with the fixed fan located on one side of the ventilation window.

[0020] Preferably, the first connecting pipe is connected to an inlet pipe, and the second connecting pipe is connected to an outlet pipe, forming a closed-loop water cooling cycle.

[0021] Compared with the prior art, the beneficial effects of the present invention are:

[0022] 1. Through the coordination of the adjustment mechanism and the cleaning mechanism, the scale can be automatically cleaned. When the electric telescopic rod drives the connecting rotating rod to rotate, the pushing protrusions on both sides alternately push the moving sealing plate, so that some water cooling pipes are blocked and some remain open. At the same time, the rotating scraper scrapes the inner wall of the water cooling pipe under the drive of the rotating component. The scale in the unblocked water cooling pipe can be flushed out due to the accelerated water flow.

[0023] 2. Through the alternating sealing and opening design of the movable sealing plate, the machine does not need to be stopped when cleaning scale. Multiple water cooling pipes work alternately to ensure the continuous operation of the water cooling system. The scale cleaning can be carried out without stopping the machine, reducing equipment failures caused by insufficient cooling and meeting the requirements of continuous power supply.

[0024] 3. By setting up a combination structure of fixed fan and water cooling system, the cooling mode can be automatically switched according to the output power. When the generator set output power is small, only the fixed fan needs to be started to meet the heat dissipation requirements. When the power increases, cold water enters the water cooling pipe through the inlet pipe and the first connecting pipe, and then forms a circulation through the second connecting pipe and the outlet pipe. The air cooling and water cooling work together to significantly improve the cooling efficiency. Attached Figure Description

[0039] 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.

[0040] Please see Figures 1 to 13This invention provides a technical solution: an adjustable output power generator set, including a generator housing 1 and a generator set 3 disposed therein, further comprising: a first connecting pipe 4, fixed inside the generator housing 1, which connects to multiple water-cooling pipes 8; a second connecting pipe 5, connected to the upper ends of the multiple water-cooling pipes 8; an adjusting mechanism 9, disposed on the second connecting pipe 5, including multiple vertically movable sealing discs 97 and an alternating component for driving their alternating movement; and a cleaning mechanism 6, disposed inside the water-cooling pipes 8, including multiple rotating scrapers 69 and a rotating component for driving their rotation; wherein, when the alternating component drives a portion of the movable sealing discs 97 to move downward to seal the upper end of the corresponding water-cooling pipe 8, simultaneously another portion... When the movable sealing disc 97 moves upward to open the corresponding water-cooling pipe 8, the rotating component drives the rotating scraper 69 to rotate within multiple water-cooling pipes 8 to remove scale. The water flow velocity in the unblocked water-cooling pipes 8 increases, flushing and discharging the scraped scale. Through the coordination of the adjusting mechanism 9 and the cleaning mechanism 6, automatic scale removal can be achieved. When the electric telescopic rod 96 drives the connecting rotating rod 91 to rotate, the pushing protrusions 92 on both sides alternately push the movable sealing disc 97, causing some water-cooling pipes 8 to be blocked while others remain open. Simultaneously, the rotating scraper 69, driven by the rotating component, scrapes the inner wall of the water-cooling pipes 8. The unblocked water-cooling pipes 8, due to the increased water flow, can flush out the scale, which is then removed by the movable sealing disc 97. The alternating blocking and opening design eliminates the need to stop the machine during scale removal. Multiple water-cooling pipes 8 work alternately to ensure continuous operation of the water-cooling system, reducing equipment failures due to insufficient cooling and meeting the requirements for continuous power supply. The combination of a fixed fan 2 and the water-cooling system allows for automatic switching of cooling modes based on output power. When the generator set 3 has a lower output power, only the fixed fan 2 needs to be activated to meet the heat dissipation requirements. When the power increases, chilled water enters the water-cooling pipes 8 through the inlet pipe 11 and the first connecting pipe 4, then circulates through the second connecting pipe 5 and the outlet pipe 12. The combined use of air cooling and water cooling significantly improves cooling efficiency. After being connected to the working circuit, the output power of generator set 3 is adjusted and set by an external control device according to the load demand. When the output power of generator set 3 is low, the fixed fan 2 starts, and the airflow generated by it flows inside the generator housing 1, carrying away the heat generated by generator set 3 and achieving air cooling of generator set 3. When the load demand increases and the output power of generator set 3 increases, cold water flows into the first connecting pipe 4 through the water inlet pipe 11, then enters the water cooling pipe 8, is collected through the second connecting pipe 5, and flows out from the water outlet pipe 12, completing the water cooling cycle and further improving the cooling effect of generator set 3. The above power adjustment process is a mature existing technology and will not be described in detail here.

[0041] like Figures 5 to 7 as well as Figure 13As shown, the alternating assembly includes a connecting rotating rod 91 rotatably disposed inside the second connecting pipe 5. Two sets of pushing protrusions 92 are fixedly installed on the connecting rotating rod 91, and the two sets of pushing protrusions 92 are respectively located on both sides of the connecting rotating rod 91. There are multiple connecting rotating rods 91 in each set. The two sets of connecting rotating rods 91 alternately contact the corresponding movable sealing disc 97 and drive it to move downward to block the upper end of the corresponding water-cooling pipe 8. When the connecting rotating rod 91 rotates, one set of pushing protrusions 92 pushes the corresponding movable sealing disc 97 to move downward to block the water-cooling pipe 8, and the other set of pushing protrusions 92 disengages from the corresponding movable sealing disc 97, causing the movable sealing disc 97 to move upward to open the water-cooling pipe 8. A connecting support plate 98 is fixed on the movable sealing disc 97. A fixed vertical slide rod 99 slides inside the connecting support plate 98. A second connecting spring 910 is sleeved on the fixed vertical slide rod 99. One end of the second connecting spring 910 is connected to the inner wall of the second connecting pipe 5, and the other end is connected to the connecting support plate 98.

[0042] like Figures 7 to 10 As shown, the rotating assembly includes a movable pressure plate 61 fixedly installed at the lower end of the movable sealing disc 97 and a sliding support plate 62 slidably connected inside the water-cooling pipe 8. A push connecting plate 63 is hinged to the lower end of the sliding support plate 62, and a sliding toothed plate 64 is hinged to the lower end of the push connecting plate 63. A fixed horizontal plate 65 slides inside the sliding toothed plate 64. The fixed horizontal plate 65 is fixedly installed inside the water-cooling pipe 8. A first connecting spring 66 is sleeved on the fixed horizontal plate 65. One end of the first connecting spring 66 is connected to the sliding toothed plate 64, and the other end is connected to the inner wall of the water-cooling pipe 8. A first connecting gear 67 meshes on the sliding toothed plate 64. A rotating connecting rod 68 is fixedly installed at the lower end of the first connecting gear 67. A fixed support frame 610 is rotatably connected to the rotating connecting rod 68. The fixed support frame 610 is fixedly installed on the water-cooling pipe 8. A rotating scraper 69 is fixedly installed on the rotating connecting rod 68. One end of the rotating scraper 69 contacts the inner wall of the water-cooling pipe 8.

[0043] like Figures 9 to 11 As shown, when the movable sealing disc 97 moves downward, the movable pressure plate 61 pushes the sliding support plate 62 downward, causing the sliding toothed plate 64 to slide along the fixed horizontal plate 65 and compress the first connecting spring 66. The sliding toothed plate 64 drives the first connecting gear 67 to rotate, which in turn drives the rotating scraper 69 to rotate in the forward direction to scrape away the scale. When the movable sealing disc 97 moves upward, the first connecting spring 66 rebounds and pushes the sliding toothed plate 64 to reset, driving the rotating scraper 69 to rotate in the reverse direction to scrape away the scale. Since some of the water cooling pipes 8 are blocked by the movable sealing disc 97, the cross-sectional area of ​​the water flow channel of the entire water cooling system is reduced. According to the principle of fluid mechanics, under the condition that the total water flow remains unchanged, the water flow velocity inside the unblocked water cooling pipes 8 is increased.

[0044] like Figure 1 and Figure 2As shown, the generator housing 1 has a ventilation window 7 on its side wall, and a fixed fan 2 is installed inside the generator housing 1. The fixed fan 2 is located on one side of the ventilation window 7. The first connecting pipe 4 is connected to the water inlet pipe 11, and the second connecting pipe 5 is connected to the water outlet pipe 12, forming a closed water cooling cycle.

[0045] By cooperating with the adjustment mechanism 9 and the cleaning mechanism 6, automatic cleaning of scale can be achieved. When the electric telescopic rod 96 drives the connecting rotating rod 91 to rotate, the pushing protrusions 92 on both sides alternately push the moving sealing plate 97, so that some water-cooling pipes 8 are blocked and some remain open. At the same time, the rotating scraper 69 scrapes the inner wall of the water-cooling pipe 8 under the drive of the rotating component. The scale in the unblocked water-cooling pipes 8 can be flushed out due to the accelerated water flow. Through the alternating blocking and opening design of the moving sealing plate 97, there is no need to stop the machine when cleaning scale. Multiple water-cooling pipes 8 work alternately to ensure the continuous operation of the water-cooling system. There is no need to stop the machine when cleaning scale, which reduces equipment failure caused by insufficient cooling and meets the need for continuous power supply.

[0046] After generator set 3 is connected to the working circuit, the output power of generator set 3 is adjusted and set by an external control device according to the load demand. When the output power of generator set 3 is low, the fixed fan 2 starts, and the airflow generated by it flows inside the generator housing 1, carrying away the heat generated by generator set 3 and realizing air cooling of generator set 3. When the load demand increases and the output power of generator set 3 increases, cold water flows into the first connecting pipe 4 through the water inlet pipe 11, then enters the water cooling pipe 8, is collected through the second connecting pipe 5, and flows out from the water outlet pipe 12, completing the water cooling cycle and further improving the cooling effect of generator set 3.

[0047] As the water cooling system operates for a long time, scale will gradually form on the inner wall of the water cooling pipe 8. In order to avoid the accumulation of scale, after a period of operation, the electric telescopic rod 96 is activated. The electric telescopic rod 96 drives the moving rack plate 95 to slide on the sliding connecting groove 93. The moving rack plate 95 drives the second connecting gear 94 to rotate, which in turn drives the connecting rotating rod 91 to rotate. The pushing protrusions 92 on both sides of the connecting rotating rod 91 move accordingly, with some pushing the protrusions 92 to rotate downward and the other part pushing the protrusions 92 to rotate upward. When the partially pushing protrusion 92 rotates downwards, pushing the movable sealing disc 97 downwards, the connecting support plate 98 moves down along the fixed vertical slide rod 99 and compresses the second connecting spring 910. The sealing rubber ring at the lower end of the movable sealing disc 97 fits against the upper end of the water-cooling pipe 8 to achieve sealing. At the same time, the movable pressure plate 61 at the lower end of the movable sealing disc 97 pushes the sliding support plate 62 downwards in the inner slide groove 60. The sliding support plate 62 drives the sliding toothed plate 64 to slide along the fixed horizontal plate 65 through the pushing connecting plate 63 and squeezes the first connecting spring 66. The sliding toothed plate 64 drives the first connecting gear 67 to rotate, which is then driven to rotate via the rotating connecting rod 68. The scraper 69 rotates inside the water-cooling pipe 8 to scrape away scale; while another part pushes the protrusion 92 to rotate upward, and the corresponding movable sealing disc 97 moves upward under the elastic force of the second connecting spring 910, keeping the corresponding water-cooling pipe 8 in an open state. At this time, the first connecting spring 66 rebounds and pushes the sliding toothed plate 64 to reset, which again drives the rotating scraper 69 to rotate in the opposite direction to further clean the scale. Because some water-cooling pipes 8 are blocked, the water flow speed in the unblocked water-cooling pipes 8 is accelerated, and the scraped scale is discharged with the water flow through the second connecting pipe 5 and the outlet connecting pipe 12, realizing efficient removal and discharge of scale, and ensuring the continuous and stable operation of the water-cooling system.
