Description

Technical Field

[0001] The utility model relates to the field of active filtering devices, in particular to a low-energy consumption active filtering device. Background Art

[0002] Active filtering device, also called active filter, is a new type of power electronic device used for dynamic harmonic suppression and reactive power compensation. It can compensate for harmonics of varying magnitude and frequency as well as varying reactive power. The reason why active filter is called active is that, as the name implies, the device needs to provide power to compensate for the harmonics of the main circuit. Its application can overcome the shortcomings of traditional harmonic suppression and reactive power compensation methods such as LC filters. Traditional methods can only provide fixed compensation, while dynamic tracking compensation is realized. It can compensate for both harmonics and reactive power. Low-energy active filtering device is also one of the many active filters.

[0003] The invention discloses a sturdy active filtering device with the publication number of CN211046484U, which specifically discloses a sturdy active filtering device, including a fixed seat, a clamping rod and a sliding ball. A clamping hole is installed inside the fixed seat, and a rotating block is installed on the inner side of the clamping hole. The rotating block and the fixed seat are movably connected. The movable plate is fixed on the top of the rotating block, and a clamping rod runs through the inside of the movable plate. The clamping rod and the movable plate are movably connected. The sliding ball is arranged at the bottom of the clamping rod, and a clamping spring is installed on the outer side of the sliding ball. The sliding ball and the clamping rod are movably connected, and the clamping spring and the clamping rod are fixedly connected. A main body is arranged above the movable plate, and a display screen is installed inside the main body. The movable plate and the main body are movably connected. The sturdy active filtering device provided by the utility model has a rubber strip, which can protect the surrounding of the main body to prevent the surrounding of the device from directly contacting the ground when the device falls, thereby avoiding the possibility of the outer shell of the device being broken.

[0004] During the use of the existing low-energy active filtering device, a certain amount of heat is accumulated inside the low-energy active filtering device during operation. If the heat is not dissipated, the normal operation of the low-energy active filtering device will be affected. However, during the heat dissipation process, external dust will enter the interior of the low-energy active filtering device through the heat dissipation port, causing a certain impact on the internal components. In addition, the above-mentioned comparative case lacks a method for auxiliary heat dissipation and dust filtering. In this way, under long-term use, it is necessary to manually disassemble the internal components regularly to clean the internal dust, thereby delaying the normal use of the low-energy active filtering device. Frequent disassembly will also cause certain losses to the low-energy active filtering device.

[0005] Therefore, it is necessary to invent a low-energy consumption active filtering device to solve the above problems. Utility Model Content

[0027] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0028] The utility model provides Figure 1-5 A low-energy consumption active filter device shown includes a low-energy consumption active filter body 1, which is used to carry and install components for the active filter device;

[0029] The fixing bolt 8 passes through the outside of the low-energy active filter body 1 and is used to connect and install the front packaging cover 9. The display controller 10 is arranged outside the front packaging cover 9, and the heat dissipation fin 11 is fixedly installed below the display controller 10.

[0030] The inner filter frame 12 is arranged inside the low-energy active filter body 1 to isolate dust from entering, and a sliding groove 13 is provided inside the inner filter frame 12, a sliding block 14 is movably connected inside the sliding groove 13, and a built-in filter screen 15 is fixedly installed at one end of the sliding block 14;

[0031] The drive controller 16 is arranged on the back of the low-energy active filter body 1, and is used for assisting in controlling and adjusting the size of the heat dissipation port 17. A heat dissipation port 17 is provided on one side of the low-energy active filter body 1. A rotating shaft 18 is arranged inside the heat dissipation port 17. A heat dissipation fan blade 19 is fixedly installed outside the rotating shaft 18. A connecting rod 20 is fixedly installed on one side of the heat dissipation fan blade 19. A micro-telescopic air pump 21 is arranged above the connecting rod 20. The drive controller 16 controls the micro-telescopic air pump 21 to drive the connecting rod 20 to extend and retract up and down, so that the connecting rod 20 links the heat dissipation fan blade 19 to unfold in the heat dissipation port 17. The heat dissipation port 17 is opened to allow the heat accumulated inside the low-energy active filter body 1 to be discharged smoothly through the heat dissipation ports 17 on both sides. In addition, the inner filter frame 12 and the built-in filter screen 15 arranged inside the low-energy active filter body 1 do not affect the normal heat dissipation of the low-energy active filter device, and can also prevent dust from entering the interior of the low-energy active filter body 1 through the heat dissipation port 17 for accumulation, causing certain losses to the internal components.

[0032] like Figure 1 , Figure 2 and Figure 3 As shown, a positioning column 2 is fixedly installed at the bottom of the low-energy active filter body 1, and a threaded bracket 3 is movably connected inside the positioning column 2. If the low-energy active filter device is used alone, the threaded bracket 3 can be twisted under the positioning column 2, and the device can be directly placed outside for single use. A mounting plate 4 is fixedly installed outside the low-energy active filter body 1, and an adjustment groove 5 is opened on the surface of the mounting plate 4. A tightening gasket 6 is arranged above the adjustment groove 5, and a positioning bolt 7 is passed through the tightening gasket 6. According to the current usage, if it is installed in series in a cabinet, the device can be installed at any position of the cabinet through the mounting plate 4, the adjustment groove 5, the tightening gasket 6 and the positioning bolt 7, so that the low-energy active filter device and other equipment can be used together. The number of heat dissipation fins 11 is set to four, and the four heat dissipation fins 11 are evenly spaced on the front packaging cover 9. The heat dissipation fins 11 are attached to the front packaging cover 9, and the heat stored in the front of the low-energy active filter body 1 can be heat-dissipated.

[0033] like Figure 1 , Figure 4 and Figure 5As shown, the built-in filter 15 is slidably connected to the inner filter frame 12, and the sliding block 14 is used in conjunction with the sliding groove 13. The sliding block 14 and the sliding groove 13 are convenient for pulling out the built-in filter 15 for cleaning after long-term use, thereby ensuring the normal use of the device. The heat dissipation fan blades 19 are movably connected to the heat dissipation port 17, and the rotating shafts 18 are evenly spaced on the heat dissipation port 17. The heat dissipation fan blades 19 of the heat dissipation port 17 of the low-energy active filter device in the unstarted state are in a closed state, which can prevent external dust from entering the low-energy active filter body 1.

[0034] The practical working principle of the present invention is as follows: firstly, the external power supply is turned on. According to the current usage, if the low-energy active filtering device is installed in series on the cabinet, the device can be installed at any position of the cabinet through the mounting plate 4, the adjusting slot 5, the tightening gasket 6 and the positioning bolt 7, so that the low-energy active filtering device and other equipment can be used together. Then, if the low-energy active filtering device is used alone, the threaded tripod 3 can be screwed on under the positioning column 2, and the device can be directly placed in the outside for single use, thus expanding the overall use range of the device. Then, the heat dissipation fan blades 19 of the heat dissipation port 17 of the low-energy active filtering device in the unstarted state are in a closed state, which can prevent external dust from entering the low-energy active filter body 1. Subsequently, after the low-energy active filtering device is started, the driving controller 16 controls the micro-telescopic air pump 21 to drive the connecting rod 20 to extend and retract up and down, so that the connecting rod 20 can be linked with the heat dissipation fan blades 19 in the heat dissipation. The heat dissipation opening 17 is unfolded, and the heat dissipation opening 17 is opened to allow the heat accumulated inside the low-energy active filter body 1 to be smoothly discharged through the heat dissipation openings 17 on both sides. Then, the inner filter frame 12 and the built-in filter screen 15 arranged inside the low-energy active filter body 1 do not affect the normal heat dissipation of the low-energy active filter device, and can also prevent dust from entering the interior of the low-energy active filter body 1 through the heat dissipation opening 17 and accumulating, causing certain losses to the internal components. Then, the heat dissipation fins 11 are attached to the front packaging cover 9, and the heat stored in the front of the low-energy active filter body 1 can be heat-dissipated through the front packaging cover 9. In this way, the low-energy active filter device after heat dissipation can be used normally. Finally, after completing the installation and use of all the low-energy active filter devices according to the above operations, the device is maintained daily. If it is not used for a long time, the external power supply can be cut off. In this way, the use process of the low-energy active filter device is completed.

[0035] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
