Its concept emphasizes more on the functions and effects presented to the outside world, updates the operating concept and generates social and economic benefits, and meets the needs and direction of power development. The virtual power plant can be regarded as an advanced regional centralized power management model and an effective form of efficient utilization of large-scale new energy power. New energy sources such as wind energy and solar energy have a power generation method that determines the volatility and randomness of the electricity they generate. The virtual power plant can effectively integrate the power storage generated by new energy, combine it with traditional energy, and intelligently coordinate to achieve the effect of intelligent power output.

[0003] According to the Chinese patent with the announcement number: CN218919621U, a virtual power plant device includes an external shell with a virtual power plant system electronic control host installed inside, a working condition display control panel for displaying the operating status of the virtual power plant system, and a centrifugal fan. The virtual power plant device of the utility model uses the wind pressure generated by the centrifugal fan as the power to control the bottom scraper located at the bottom of the bottom air inlet to drive it in translation, thereby removing dust from the metal filter frame of the bottom air inlet, greatly improving the flux of the bottom air inlet, and maintaining the heat dissipation effect; the bottom scraper is controlled by an elastic extrusion reset cylinder installed on the inner side of the lower air inlet groove, which not only has strong control stability, but also can be elastically extruded and reset, making it more convenient to use.

[0004] In the above scheme, the bottom scraper located at the bottom of the bottom air inlet is controlled to be driven in translation through a centrifugal fan, thereby removing dust from the metal filter frame of the bottom air inlet. This leads to the following disadvantages: when the scraper is removing dust from the filter, it cannot completely cover the filter, resulting in dust accumulation at the corners of the filter, and the speed of inhaling dust is not ideal, thereby reducing the use effect of the centrifugal fan. Utility Model Content

[0005] The purpose of the utility model is to provide a virtual power plant device to solve the problem that the scraper cannot completely cover the filter screen when removing dust, resulting in dust accumulation at the corners of the filter screen, and the speed of inhaling dust is not ideal, thereby reducing the use effect of the centrifugal fan.

[0006] In order to achieve the above-mentioned purpose of the utility model, the utility model adopts the following technical scheme: a virtual power plant device, including a base plate, the base plate is fixed to the bottom surface of the centrifugal fan casing, the inner cavity of the centrifugal fan casing is provided with a rotating shaft, the outer wall of the rotating shaft is fixed with a circular plate, a fixing ring is fixed to one side of the circular plate, the outer wall of the fixing ring is sleeved with two fixing bolts, the two fixing bolts pass through the fixing ring and are threadedly connected with the outer wall of the rotating shaft, a reinforcement ring is fixed to the other side of the circular plate, a plurality of long fan blades are fixed to the other side of the circular plate, the long fan blades are fixed to the reinforcement ring at the same time, a brush is fixed to the top of the rotating shaft, and a filter circular net is provided at the air inlet of the centrifugal fan casing.

[0011] Preferably, a cooling fan is provided on one side of the driving motor, the cooling fan and the heat sink cooperate with the driving motor, and a cooling plate is provided on one side of the cooling fan.

[0012] Compared with the prior art, a virtual power plant device using the above technical solution has the following beneficial effects:

[0013] 1. During use, the centrifugal fan filter can be cleaned by rotating the shaft and the brush, which prevents the centrifugal fan from being blocked when inhaling dust, and helps the centrifugal fan to work for a long time without manual cleaning, thereby improving the stability of the centrifugal fan during use. This structure is easy to use and effectively saves manpower and material resources. After the fixing ring behind the circular plate is inserted into the fixing bolt, it can be more firmly fixed to the output end of the drive motor, greatly enhancing the safety of the long fan blades during rotation. By starting the drive motor, the long fan blades are driven to rotate, which increases the dust inhalation speed and improves work efficiency.

DETAILED DESCRIPTION

[0020] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings.

[0021] like Figure 1-Figure 4 As shown, a virtual power plant device includes a base plate 1, which is fixed to the bottom surface of a centrifugal fan casing 2. A rotating shaft 3 is provided in the inner cavity of the centrifugal fan casing 2. A circular plate 4 is fixed to the outer wall of the rotating shaft 3. A fixing ring 5 is fixed to one side of the circular plate 4. Two fixing bolts 6 are sleeved on the outer wall of the fixing ring 5. The two fixing bolts 6 penetrate the fixing ring 5 and are threadedly connected to the outer wall of the rotating shaft 3. A reinforcing ring 7 is fixed to the other side of the circular plate 4. A plurality of long fan blades 8 are fixed to the other side of the circular plate 4. The long fan blades 8 are fixed to the reinforcing ring 7 at the same time. A brush 9 is fixed to the top of the rotating shaft 3. A filter circular net 10 is provided at the air inlet of the centrifugal fan casing 2. An air outlet 11 is opened on the top surface of the centrifugal fan casing 2. An extended circular plate 12 is provided on one side of the centrifugal fan casing 2.

The rotation of the rotating shaft 3 can drive the brush 9 to rotate, and the long fan blades 8 rotate inside the centrifugal fan housing 2. At this time, since the bristles of the brush 9 will contact the filter cylinder 10, the bristles will clean the surface of the filter cylinder 10 during the rotation process, so the dust can be cleaned. By cleaning the surface of the filter cylinder 10, the effect of preventing the centrifugal fan from being blocked during the inhalation of dust can be achieved, which is conducive to the realization of centrifugal wind The machine works for a long time and does not need manual cleaning, which is beneficial to improve the stability of the centrifugal fan during use. This structure is easy to use and effectively saves manpower and material resources. After the fixing ring 5 behind the circular plate 4 is inserted into the fixing bolt 6, it can be more firmly fixed to the output end of the drive motor 18, which greatly enhances the safety of the long fan blades 8 during rotation. By starting the drive motor 18, the rotating shaft 3 connected to the drive motor 18 starts to rotate, thereby driving the long fan blades 8 on the circular plate 4 to rotate, thereby enhancing the dust suction speed, and the inhaled dust is discharged from the air outlet 11, thereby improving work efficiency.

[0024] During use, when the drive motor 18 is started, the centrifugal fan needs to work for a long time, causing the temperature to rise rapidly. At this time, the heat sink 19 on the outer ring of the drive motor 18 dissipates heat evenly outward, and the cooling fan 20 is started. At this time, the cooling fan 20 starts to rotate rapidly and then begins to blow hot air out evenly, thereby accelerating the air flow in the drive motor 18 and improving the heat dissipation performance, so that the drive motor 18 can maintain good performance even after long-term use.
