Description

Technical Field

[0001] This invention relates to the field of power amplifier technology, and in particular to a digital simulation power amplifier for power systems. Background Technology

[0002] Currently, simulation studies of flexible DC converters and transmission system control and protection generally employ theoretical analysis, offline PSCAD / MATLAB simulation, and RT-LAB / RTDS real-time simulation platforms. Compared to digital simulation, dynamic physical simulation systems possess physical characteristics consistent with the prototype. The relative changes in physical quantities such as current, voltage, and power occurring in the model can be mirrored in the simulated prototype system. Furthermore, effects such as saturation, hysteresis, and eddy currents, which are often neglected or approximated in theoretical analysis or offline simulation, can be more fully reflected in dynamic simulations, and these effects are often essential considerations for control and protection.

[0003] In power system simulation, power amplifiers are used to ensure sufficient power and power stability. However, existing power amplifiers tend to overheat during long-term use. To address this issue, existing power amplifiers are typically mounted on a heat sink. However, after prolonged use, a large amount of dust accumulates on the bottom of the heat sink. If the dust is not cleaned in time, it can affect the heat dissipation efficiency of the heat sink. The current method for cleaning the heat sink involves removing the base and cleaning the internal dust. This method is time-consuming and involves complex procedures. Therefore, there is an urgent need for a power amplifier that allows for easy cleaning of the dust inside the base. Summary of the Invention

[0004] The purpose of this invention is to at least solve one of the technical problems existing in the prior art, and to provide a power amplifier for digital simulation of power systems that can solve the problem of easy cleaning of dust in the power amplifier base.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a power amplifier for digital simulation of a power system, comprising a base, a power amplifier body disposed on the top surface of the base, two dust boxes disposed on the bottom surface of the base, each dust box having a bolt threadedly connected to the base, a first knob rotatably connected to the right surface of the base, and second knobs rotatably connected to the left and right surfaces of the base, two grooves formed on the top surface of the base, both grooves communicating with the interior of the base, ventilation holes formed on the top surface of the base communicating with the interior of the base, a fixing plate fixedly connected to the bottom surface of the inner wall of the base, a fan fixedly connected to the top surface of the fixing plate, a quick-fixing device disposed inside the base, a transmission component disposed inside the base, and a dust cleaning device disposed inside the base, two connecting pieces fixedly connected to the bottom surface of the power amplifier body, each connecting piece having a slot on its bottom surface, the two connecting pieces slidingly connected to the two grooves respectively, and sliding grooves formed on the front and rear surfaces of the inner wall of the base, the rear surface of the inner wall of the base... The surface has a connecting groove, and the bottom surface of the inner wall of the base has two dust collection grooves, which are respectively connected to the interior of two dust boxes. The quick fixing device includes a bidirectional threaded rod, the right end of which passes through the base and is fixedly connected to the first knob. The threads on the left and right sides of the outer wall of the bidirectional threaded rod are in opposite directions. A limit ring is fixedly sleeved on the bidirectional threaded rod. Two fixing sleeves are symmetrically threaded on the bidirectional threaded rod. A connecting plate is fixedly connected to the rear surface of each fixing sleeve. The two connecting plates are slidably connected to the connecting groove. The transmission assembly includes two driven sprockets, which are rotatably connected to the interior of the base. A chain is meshed on the two driven sprockets, and a driving sprocket is meshed on the chain. There are two transmission assemblies, which are respectively set on the left and right surfaces of the inner wall of the base. The dust cleaning device includes a threaded sleeve, which is threaded onto the threaded rod. Movable plates are fixedly connected to the front and rear surfaces of the threaded sleeve, and scrapers are fixedly connected to the bottom surfaces of the two movable plates.

[0006] Preferably, two magnets are fixedly connected to the left and right surfaces of the inner wall of the base, and the two connecting pieces are in contact with the four magnets respectively.

[0007] Preferably, threaded rods are fixedly connected to the opposite faces of the two drive sprockets, the opposite ends of the two threaded rods penetrate the base and are rotatably connected to the base, the opposite ends of the two threaded rods are fixedly connected to two second knobs respectively, and limit blocks are fixedly connected to the opposite ends of the two threaded rods.

[0008] Preferably, there are two dust cleaning devices, each mounted on a threaded rod, with four movable plates slidably connected to two sliding grooves, and both scrapers in contact with the bottom surface of the inner wall of the base.

[0009] Compared with the prior art, the beneficial effects of the present invention are:

[0010] (1) The power system digital simulation power amplifier, through the setting of the dust cleaning device, uses the scraper to push the dust accumulated on the bottom surface of the inner wall of the base into the dust collection trough, and sends the dust into the dust box through the dust collection trough. Through the setting of this device, the dust accumulated on the bottom surface of the inner wall of the base can be cleaned without disassembling the base, thereby improving the convenience of cleaning the dust on the inner wall of the base.

[0011] (2) The power system digital simulation power amplifier can be cleaned by simply turning the second knob, making the device more convenient to use. At the same time, the setting of the limit block can limit the threaded sleeve, preventing the threaded sleeve from coming off the threaded rod and reducing the failure rate of the device.

[0012] (3) The power system digital simulation power amplifier can stabilize the threaded sleeve by setting the moving plate, making the threaded sleeve more stable during movement and improving the reliability of the device.

[0013] (4) The power amplifier digital simulation power amplifier of the power system can quickly fix the power amplifier body on the top surface of the base by setting a quick fixing device. Compared with the traditional method of fixing with screws, the device only requires the power amplifier body to be placed and the first knob to be turned when fixing the power amplifier body. This can install the power amplifier body more quickly, thereby improving the speed of installation and disassembly of the device.

[0014] (5) The power system digital simulation power amplifier, through the setting of the connecting plate, can ensure the stability of the fixed sleeve when it moves, and prevent the fixed sleeve from rotating, thereby improving the stability of the device.

[0015] (6) The digital simulation power amplifier of the power system can attract the connecting piece by setting the magnet, so as to ensure that the connecting piece is placed in the correct position, thereby improving the practicality of the device. Attached Figure Description

[0028] Example 1:

[0029] Please see Figure 1-6 This invention provides a technical solution: a power amplifier for digital simulation of a power system includes a hollow base 1. A power amplifier body 2 is mounted on the top surface of the base 1. The power amplifier body 2 is an existing structure and will not be described in detail here. Two dust boxes 3 are mounted on the bottom surface of the base 1. Each dust box 3 is equipped with a bolt 28, which is threadedly connected to the base 1. The dust boxes 3 are connected to the base 1 via the bolts 28. A first knob 8 is rotatably connected to the right surface of the base 1, and second knobs 9 are rotatably connected to both the left and right surfaces of the base 1. Two grooves 4 are formed on the top surface of the base 1, both of which communicate with the interior of the base 1. A ventilation hole 5 is formed on the top surface of the base 1, also communicating with the interior of the base 1. Two connecting pieces 6 are fixedly connected to the bottom surface of the power amplifier body 2. Each connecting piece 6 has a slot 7 on its bottom surface, and the two connecting pieces 6 are slidably connected to the two grooves 4 respectively.

[0030] Furthermore, a fixing plate 17 is fixedly connected to the bottom surface of the inner wall of the base 1, and a fan 18 is fixedly connected to the top surface of the fixing plate 17. The fan 18 is an existing structure and will not be described in detail here. When using the device, the fan 18 is started by connecting an external power supply to generate airflow. The airflow enters the interior of the power amplifier body 2 through the ventilation hole 5, thereby completing the heat dissipation of the power amplifier body 2 and improving the heat dissipation performance of the device.

[0031] Furthermore, the front and rear surfaces of the inner wall of the base 1 are provided with sliding grooves 11, the rear surface of the inner wall of the base 1 is provided with a connecting groove 10, the bottom surface of the inner wall of the base 1 is provided with two dust collection grooves 19, the two dust collection grooves 19 are respectively connected to the interior of the two dust boxes 3, and the left and right surfaces of the inner wall of the base 1 are respectively fixedly connected with two magnets 16, and the two connecting pieces 6 are respectively in contact with the four magnets 16.

[0032] Example 2;

[0033] Please see Figure 1-6 Based on Embodiment 1, a quick-fixing device is provided inside the base 1. The quick-fixing device includes a bidirectional threaded rod 12. The right end of the bidirectional threaded rod 12 passes through the base 1 and is fixedly connected to the first knob 8. The threads on the left and right sides of the outer wall of the bidirectional threaded rod 12 are opened in opposite directions. A limit ring 13 is fixedly sleeved on the bidirectional threaded rod 12. Two fixing sleeves 14 are symmetrically threaded on the bidirectional threaded rod 12. A connecting plate 15 is fixedly connected to the rear surface of each of the two fixing sleeves 14. The two connecting plates 15 are slidably connected to the connecting groove 10 respectively.

[0034] Furthermore, when using the device, when the two connecting pieces 6 enter the interior of the base 1 through the groove 4, so that the lower ends of the two connecting pieces 6 respectively come into contact with the four magnets 16, then the first knob 8 is turned to drive the bidirectional threaded rod 12 to rotate. The rotation of the bidirectional threaded rod 12 drives the two fixing sleeves 14 to move, so that the two fixing sleeves 14 are tightly fitted with the two connecting pieces 6 respectively, thereby fixing the two connecting pieces 6 firmly.

[0035] Furthermore, the quick-fixing device allows for rapid fixation of the power amplifier body 2 to the top surface of the base 1. Compared to the traditional screw-fixing method, this device allows for quicker installation of the power amplifier body 2 by simply placing it in place and then turning the first knob 8. This significantly improves the speed of installation and disassembly. Additionally, the connecting plate 15 ensures stability during the movement of the fixing sleeve 14, preventing rotation and enhancing the device's stability. Furthermore, the magnet 16 attracts the connecting piece 6, ensuring its correct placement and enhancing the device's practicality.

[0036] Example 3;

[0037] Please see Figure 1-6 Based on Embodiment 1 and Embodiment 2, a transmission assembly is provided inside the base 1. The transmission assembly includes two driven sprockets 20, both of which are rotatably connected inside the base 1. A chain 22 is meshed on the two driven sprockets 20, and a drive sprocket 21 is meshed on the chain 22. There are two transmission assemblies, which are respectively set on the left and right surfaces of the inner wall of the base 1.

[0038] Furthermore, threaded rods 23 are fixedly connected to the opposite faces of the two drive sprockets 21. The opposite ends of the two threaded rods 23 pass through the base 1 and are rotatably connected to the base 1. The opposite ends of the two threaded rods 23 are fixedly connected to the two second knobs 9 respectively. Limit blocks 24 are fixedly connected to the opposite ends of the two threaded rods 23. When using the device, the threaded rods 23 are rotated by rotating the second knobs 9.

[0039] Furthermore, a dust cleaning device is provided inside the base 1. The dust cleaning device includes a threaded sleeve 25, which is threaded onto the threaded rod 23. Movable plates 26 are fixedly connected to the front and rear surfaces of the threaded sleeve 25. Scrapers 27 are fixedly connected to the bottom surfaces of the two movable plates 26. There are two dust cleaning devices, which are respectively set on the two threaded rods 23. The four movable plates 26 are slidably connected to the two sliding grooves 11. The two scrapers 27 are in contact with the bottom surface of the inner wall of the base 1.

[0040] Furthermore, when using this device, the threaded rod 23 rotates to drive the threaded sleeve 25 to move, the threaded sleeve 25 moves to drive the moving plate 26 to move, and the moving plate 26 moves to drive the scraper 27 to move.

[0041] Furthermore, by using the dust cleaning device, the scraper 27 moves to push the dust accumulated on the bottom surface of the inner wall of the base 1 into the dust collection trough 19, and then the dust is sent into the dust box 3 through the dust collection trough 19. With this device, the dust accumulated on the bottom surface of the inner wall of the base 1 can be cleaned without disassembling the base 1, thereby improving the convenience of cleaning the dust on the inner wall of the base 1. At the same time, cleaning only requires turning the second knob 9, making the device more convenient to use. Meanwhile, the limiting block 24 can limit the threaded sleeve 25, preventing the threaded sleeve 25 from detaching from the threaded rod 23, reducing the failure rate of the device. The moving plate 26 can stabilize the threaded sleeve 25, making the threaded sleeve 25 more stable during movement, thus improving the reliability of the device.

[0042] Working principle:

[0043] When using this device, firstly, the two connecting pieces 6 enter the interior of the base 1 through the grooves 4, so that the lower ends of the two connecting pieces 6 contact the four magnets 16 respectively. Then, the first knob 8 is turned to drive the bidirectional threaded rod 12 to rotate. The rotation of the bidirectional threaded rod 12 drives the two fixing sleeves 14 to move, so that the two fixing sleeves 14 are tightly fitted with the two connecting pieces 6 respectively, thereby fixing the two connecting pieces 6 firmly. Then, by connecting an external power source, the fan 18 is started to generate airflow. The airflow enters the interior of the power amplifier body 2 through the ventilation hole 5, thereby completing the heat dissipation of the power amplifier body 2 and improving the heat dissipation performance of the device. Then, by turning the second knob 9, the threaded rod 23 is rotated. The rotation of the threaded rod 23 drives the threaded sleeve 25 to move. The movement of the threaded sleeve 25 drives the moving plate 26 to move. The movement of the moving plate 26 drives the scraper 27 to move. Finally, the movement of the scraper 27 pushes the dust accumulated on the bottom surface of the inner wall of the base 1 into the dust collection groove 19. The dust is then sent into the dust box 3 through the dust collection groove 19.

[0044] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
