Description

Technical Field

[0001] This utility model relates to the field of power equipment technology, specifically to a harmonic control and energy-saving device. Background Technology

[0002] To avoid the distortion of current and voltage in the power grid caused by harmonics, which leads to instability and reduced energy efficiency in the power system, harmonic mitigation devices are used to eliminate or reduce the additional losses generated by harmonic currents on the system impedance. This is a way to improve power quality and ensure reliable power supply.

[0003] Chinese patent document CN220273119U discloses a high-efficiency harmonic mitigation device. A motor enables a synchronous belt to move, and a moving block on the side wall of the synchronous belt drives a push rod to move a moving plate, which in turn moves the outer casing and the cooling fan. When the moving block, which is flexibly connected to the synchronous belt, passes around a synchronous pulley with the synchronous belt, the moving plate can be repeatedly moved within a fixed frame through the synchronous belt, the moving block, and the push rod. This allows the cooling fan inside the outer casing to dissipate heat at different heights within the cabinet, thereby reducing the need for electrical equipment installation, lowering installation costs, and providing heat dissipation over a wide area.

[0004] In the above solution, the heat dissipation area is increased by moving the cooling fan back and forth along the height of the cabinet. However, the electrical components inside the cabinet usually operate synchronously and generate heat at the same time. The up-and-down movement of the cooling fan causes intermittent periods in the heat dissipation of the electrical components, making the heat dissipation effect unevenly distributed and potentially causing localized overheating in some areas.

[0030] Example 1

[0031] like Figure 1-5 As shown, the harmonic control energy-saving device proposed in this utility model includes a cabinet 1, a dustproof net 6, a fan 10, and a mounting shell;

[0032] The fan 10 is arranged on one side of the cabinet 1 and facing the inside of the cabinet 1. The front of the fan 10 is provided with a diffusion component that is connected to the cabinet 1 and diffuses the air delivered by the fan 10 to the inside of the cabinet 1 when in use.

[0033] The mounting shell is wrapped around the outside of the fan 10 and connected to the cabinet 1. The mounting shell is connected to the diffuser assembly to form a cavity 17 for accommodating the fan 10.

[0034] The dust filter 6 is located on the back of the mounting housing and on the back of the fan 10. The dust filter 6 has a soft magnetic strip (not shown in the figure) at its edge, which allows the dust filter 6 to be attached to the mounting housing and to filter the outside air when the fan 10 delivers outside air to the inside of the mounting housing.

[0035] In this embodiment, the fan 10 is first installed inside the mounting housing to ensure it is firmly fixed. Then, the diffuser assembly is installed on the designated side of the cabinet 1, and the mounting housing is adjusted to completely enclose the diffuser assembly and is firmly connected to the cabinet 1. During this process, it is necessary to ensure that the fan 10 is facing the diffuser assembly to optimize airflow. Then, the fan 10 is started to deliver outside air to the diffuser assembly. When the air flows into the mounting housing, the dust filter 6 automatically filters the air, removes impurities and particles, and restricts the air delivered by the fan 10 to the diffuser assembly through the cavity 17 formed by the connection between the mounting housing and the diffuser assembly, thus preventing air leakage. The filtered clean air is guided by the diffuser assembly and stably delivered into the interior space of the cabinet 1 in a large-area uniform distribution, thereby significantly improving the heat dissipation efficiency and overall heat dissipation effect inside the cabinet 1.

[0036] Example 2

[0037] like Figure 1 and Figure 3 As shown, the harmonic control energy-saving device proposed in this utility model differs from the first embodiment in that the diffusion component includes a first perforated plate 2, a conveying shell 3, and a second perforated plate 8.

[0038] The first perforated plate 2 is installed on the inside of the cabinet 1 and has multiple air vents on its surface;

[0039] The second perforated plate 8 is installed on the outside of the cabinet 1 and located inside the mounting shell. The surface of the second perforated plate 8 has multiple air inlets.

[0040] There are multiple conveying shells 3, which are arranged at equal intervals between the first orifice plate 2 and the second orifice plate 8, and are coaxially arranged with the air outlet of the first orifice plate 2 and the air inlet of the second orifice plate 8. The inner diameter of the conveying shell 3 gradually increases from the second orifice plate 8 toward the first orifice plate 2 along the axial direction of the conveying shell 3. The air inlet of the second orifice plate 8 and the air outlet of the first orifice plate 2 are respectively arranged to match the size of one end of the conveying shell 3, and the expansion angle of the conveying shell 3 is ≤15° to avoid the air separating from the wall surface due to the excessive angle, generating eddies, increasing resistance and causing uneven air output.

[0041] In this embodiment, multiple conveying shells 3 are installed on one side of the cabinet 1 via the first perforated plate 2. The conveying shells 3 introduce air through the air inlet of the second perforated plate 8. The gradually expanding inner diameter keeps the air stable during transmission. The second perforated plate 8 is installed at the small opening of the conveying shell 3 and forms a cavity 17 with the mounting shell. This ensures that all air from the fan 10 must be delivered through the conveying shell 3, completely avoiding air leakage and short-circuiting, improving air utilization, and further ensuring that the air is evenly distributed to the air outlet of the first perforated plate 2. This improves air delivery efficiency and diffusion effect, making the heat dissipation performance of the internal space of the cabinet 1 more excellent.

[0042] Example 3

[0043] like Figure 4 As shown, the harmonic control energy-saving device proposed in this utility model differs from the first embodiment in that the mounting shell includes a cover plate 4, a shell 5, and a limiting plate 14.

[0044] The housing 5 is installed on the side of the cabinet 1 and wraps around the outside of the fan 10. The back of the housing 5 is provided with a groove 7, the bottom of the groove 7 has a ventilation hole, and the dustproof net 6 is located inside the groove 7 and is attached to the housing 5.

[0045] The limiting plate 14 is disposed on the inner side of the housing 5 and is connected to the fan 10 and the second hole plate 8;

[0046] The cover plate 4 covers the side of the housing 5 and is connected to the fan 10. The cover plate 4, housing 5, limiting plate 14 and second hole plate 8 are connected to form a cavity 17 for accommodating the fan 10.

[0047] In an optional embodiment, the inner side of the housing 5 is provided with a connecting plate 12. There are at least two connecting plates 12, which are respectively connected to the housing 5 and the limiting plate 14. The connecting plate 12 is connected to the cover plate 4 by bolts, so as to make the cover plate 4 and the housing 5 detachably connected, which facilitates the inspection and maintenance of the internal structure.

[0048] In an optional embodiment, a pad 11 connected to the fan 10 is provided on the side of the cover plate 4 and inside the housing 5, so that the cover plate 4 can press and fix the fan 10 through the pad 11 during use, and the fan 10 can be installed inside the housing 5.

[0049] In an optional embodiment, the inner side of the housing 5 and the middle of the cover plate 4, as well as the top and bottom of the fan 10, are provided with protrusions 13. Mounting plates 16 are provided at both ends of the fan 10. The protrusions 13 are located between the two mounting plates 16 and are arranged in accordance with the spacing between the two mounting plates 16, so as to make the fan 10 more securely installed and prevent displacement or loosening caused by vibration during operation, thereby ensuring the sealing and stability of the overall structure.

[0050] In an optional embodiment, a wire hole 15 is provided at the end of the limiting plate 14, and a wiring hole 9 is provided at the middle of the first hole plate 2 and the second hole plate 8. The wire of the fan 10 passes through the wire hole 15 and the wiring hole 9 and extends to the inside of the cabinet 1, which makes it easier to connect the wire of the fan 10.

[0051] In this embodiment, the position of the fan 10 inside the housing 5 is limited by the limiting plate 14, and the mounting plates 16 at both ends of the fan 10 cooperate with the protrusions 13, so that the protrusions 13 further limit the fan 10 between the two mounting plates 16. The cover plate 4 is connected to the connecting plate 12 and the cabinet 1 by bolts, and the cover plate 4 presses the fan 10 by the pad 11, thereby achieving a stable installation of the fan 10 and preventing it from shifting or loosening during operation.

[0052] In this invention, the first perforated plate 2, the conveying shell 3, and the second perforated plate 8 are connected as a whole. The first perforated plate 2 is installed on one side of the cabinet 1. At the same time, the shell 5 is installed on the side of the cabinet 1 and wrapped around the outside of the second perforated plate 8. The wire of the fan 10 is placed through the wire hole 15. The fan 10 is installed between the limiting plate 14 and the top inner side of the shell 5. The protrusion 13 slides between the two mounting plates 16 to limit the position of the fan 10 inside the shell 5 and to position the fan 10 towards the second perforated plate 8. The cover plate 4 is connected to the connecting plate 12 and the cabinet 1 with bolts, and the cover plate 4 is pressed against the fan 10 by the pad 11, thereby achieving a stable installation of the fan 10. The dustproof net 6 is installed in the recessed area. Inside the slot 7, after the fan 10 is started, the fan 10 moves the air outside the housing 5 to the cavity 17. During this process, the dust filter 6 automatically filters the air, removes impurities and particles, and the purified air moves to the second perforated plate 8 and is introduced into the inside of the conveying shell 3 through the air inlet of the second perforated plate 8. With the help of the gradually expanding inner diameter of the conveying shell 3, the air remains stable during the transmission process and diffuses into the inside of the cabinet 1. Since the second perforated plate 8 is installed at the small opening of the conveying shell 3, the inner wall of the cavity 17 ensures that all the air from the fan 10 must be sent out through the conveying shell 3, thereby preventing air leakage, improving air utilization, enhancing the conveying efficiency and diffusion effect, and making the heat dissipation performance of the internal space of the cabinet 1 more excellent.

[0053] 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 thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
