Description

Technical Field

[0001] This utility model relates to the field of power electronics technology, and in particular to a photovoltaic energy storage transformer device for preventing short circuits. Background Technology

[0002] Against the backdrop of the rapid development of photovoltaic power generation and energy storage technologies, photovoltaic energy storage transformers, as key equipment connecting photovoltaic systems and energy storage devices, play a crucial role in the operational efficiency and safety of the entire system.

[0003] When in use, photovoltaic energy storage transformers are prone to short circuits caused by the external environment, which can lead to safety accidents. Existing photovoltaic energy storage transformers are usually protected by an outer shell. However, when the photovoltaic energy storage transformer is in use, there will be a temperature difference between the inside and outside of the shell. When the ambient temperature outside the shell is low, condensation will form on the top of the shell. The condensation dripping onto the photovoltaic energy storage transformer can easily cause short circuits, leading to safety accidents.

[0004] Therefore, a photovoltaic energy storage transformer device that can absorb condensation through a desiccant, effectively preventing condensation from causing short circuits in photovoltaic energy storage transformers, and facilitating the replacement of the desiccant, has been developed to prevent short circuits. Utility Model Content

[0005] To overcome the drawback of condensation forming on the top of the photovoltaic energy storage transformer during use, which can easily cause short circuits and lead to safety accidents, this utility model provides a photovoltaic energy storage transformer device that can absorb condensation with a desiccant, effectively preventing short circuits caused by condensation, and facilitating the replacement of the desiccant.

[0006] Technical solution: A photovoltaic energy storage transformer device for preventing short circuits includes a shell, a rain shelter, a photovoltaic energy storage transformer, a dustproof net, a cooling fan, an opening and closing mechanism, and a pushing mechanism. The rain shelter is connected to the upper side of the shell, and the photovoltaic energy storage transformer is detachably connected inside the shell. Dustproof nets are connected to both the left and right sides of the shell, and two cooling fans are connected to each dustproof net. The shell is equipped with an opening and closing mechanism that can be opened and closed, and the shell is equipped with a pushing mechanism that can prevent condensation from causing short circuits in the photovoltaic energy storage transformer.

[0007] In addition, a V-shaped rain shelter is particularly preferred.

[0008] Furthermore, it is particularly preferred that the opening and closing mechanism includes opening and closing plates, gears, electric actuators, connecting frames, racks, and slide rails. Multiple opening and closing plates are rotatably connected to both sides of the outer casing. Gears are connected to the rear side of each opening and closing plate. Electric actuators are connected to the rear side of the outer casing. Connecting frames are connected to the telescopic ends of the electric actuators. Racks are connected to both sides of the connecting frames. The gears mesh with the racks. Slide rails are connected to both sides of the rear of the outer casing. The slide rails are slidably connected to the racks.

[0009] Furthermore, it is particularly preferred that the connecting frame is U-shaped.

[0010] Furthermore, it is particularly preferred that the device also includes a push-out mechanism, which includes an isolation frame, guide rods, a push-out frame, and telescopic springs. The isolation frame is connected to the upper part of the housing, and guide rods are connected to the upper sides of both the left and right sides of the isolation frame. The push-out frame slides between the guide rods, and two telescopic springs connect the push-out frame to the housing.

[0011] Furthermore, it is particularly preferred that the ejector is equipped with a pull block.

[0012] Compared with the prior art, the present invention has the following advantages: 1. The present invention can isolate condensation through the isolation frame, preventing condensation from dripping directly onto the photovoltaic energy storage transformer. At the same time, the desiccant placed on the isolation frame absorbs the condensation, achieving the effect of absorbing condensation through the desiccant, effectively preventing condensation from causing short circuits in the photovoltaic energy storage transformer, and facilitating the replacement of the desiccant.

[0013] 2. This utility model activates the electric actuator, causing the telescopic end of the electric actuator to push upward, which in turn causes the rack to slide on the slide rail. Through the meshing motion of the rack and gear, the gear rotates, causing the opening and closing plate to rotate. This achieves the effect of normal heat dissipation for the photovoltaic energy storage transformer while preventing dust from entering the photovoltaic energy storage transformer and causing a short circuit.

[0020] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of this utility model.

[0021] A photovoltaic energy storage transformer device to prevent short circuits, such as Figure 1 and Figure 2 As shown, it includes an outer shell 1, a rain shelter 2, a photovoltaic energy storage transformer 3, a dustproof net 4, a cooling fan 5, an opening and closing mechanism 6, and a pushing mechanism 7. The rain shelter 2 is connected to the upper side of the outer shell 1. The rain shelter 2 is V-shaped to facilitate the diversion of rainwater. The photovoltaic energy storage transformer 3 is detachably connected inside the outer shell 1. Dustproof nets 4 are connected to both the left and right sides of the outer shell 1. Two cooling fans 5 are connected to the front and rear of each dustproof net 4. The outer shell 1 is equipped with an opening and closing mechanism 6, and the outer shell 1 is equipped with a pushing mechanism 7.

[0022] like Figure 1 , Figure 3 and Figure 4 As shown, the opening and closing mechanism 6 includes opening and closing plates 61, gears 62, electric actuators 63, connecting frames 64, racks 65, and slide rails 66. Six opening and closing plates 61 are rotatably connected to the left and right sides of the outer casing 1. Gears 62 are connected to the rear side of each opening and closing plate 61. Electric actuators 63 are connected to the rear side of the outer casing 1. Connecting frames 64 are connected to the telescopic ends of electric actuators 63. Connecting frames 64 are U-shaped. Racks 65 are connected to the left and right sides of connecting frames 64. Gears 62 mesh with racks 65. Slide rails 66 are connected to the left and right sides of the rear of the outer casing 1. Slide rails 66 are slidably connected to racks 65.

[0023] When using this utility model, first place the outer casing 1 in the operating area of ​​the photovoltaic energy storage transformer 3, then open the outer casing 1 and install the photovoltaic energy storage transformer 3 inside the outer casing 1. During installation, the photovoltaic energy storage transformer 3 should be installed with an air gap to prevent moisture from entering the photovoltaic energy storage transformer 3 and causing corrosion and short circuits. When the photovoltaic energy storage transformer 3 is in use, the rain shelter 2 can divert and block rainwater, protecting the photovoltaic energy storage transformer 3. At the same time, the heat dissipation fan is turned on to cool the photovoltaic energy storage transformer 3, and the dustproof net 4 can block dust to prevent dust from entering the photovoltaic energy storage transformer 3 and causing short circuits. When the photovoltaic energy storage transformer 3 is in use, the electric actuator 63 is activated, causing the telescopic end of the electric actuator 63 to push upward, causing the connecting frame 64 to move upward. The rack 65 slides on the slide rail 66. Through the meshing motion of the rack 65 and the gear 62, the gear 62 rotates, causing the opening and closing plate 61 to rotate and open, thus enabling normal ventilation and heat dissipation of the photovoltaic energy storage transformer 3. After the photovoltaic energy storage transformer 3 is used, the electric push rod 63 is activated to move downward, causing the rack 65 to move downward. Through the meshing motion of the rack 65 and the gear 62, the gear 62 rotates in the opposite direction, causing the opening and closing plate 61 to rotate and close. This allows the photovoltaic energy storage transformer 3 to be covered and dustproofed after use, preventing dust from entering the outer casing 1 and causing corrosion and short circuits in the photovoltaic energy storage transformer 3. This achieves the function of normal heat dissipation of the photovoltaic energy storage transformer 3 while preventing dust from entering the photovoltaic energy storage transformer 3 and causing short circuits.

[0024] like Figure 1 and Figure 5 As shown, it also includes a push-out mechanism 7, which includes an isolation frame 71, a guide rod 72, a push-out frame 73, and a telescopic spring 74. The isolation frame 71 is connected to the upper part of the outer casing 1. The guide rods 72 are connected to the upper left and right sides of the isolation frame 71. The push-out frame 73 slides between the guide rods 72. The push-out frame 73 is provided with a pull block for easy pulling. The push-out frame 73 is connected to the outer casing 1 by two telescopic springs 74.

[0025] Using the ejection mechanism 7 of this device, the desiccant placed on the isolation frame 71 can be ejected. When the photovoltaic energy storage transformer 3 is in use, there will be a temperature difference between the inside and outside of the outer casing 1. When the ambient temperature outside the outer casing 1 is low, condensation will form on the top of the outer casing 1. Condensation dripping onto the photovoltaic energy storage transformer 3 can easily cause a short circuit. The isolation frame 71 can isolate the condensation and prevent it from dripping directly onto the photovoltaic energy storage transformer 3. At the same time, the desiccant placed on the isolation frame 71 absorbs the condensation and prevents the condensation from causing a short circuit to the photovoltaic energy storage transformer 3. When the desiccant needs to be replaced, the ejection frame 73 is pulled and slids on the guide rod 72. The telescopic spring 74 is stretched, causing the desiccant to be ejected from the ejection frame 73. After the desiccant is placed in the ejection frame 73, the ejection frame 73 is released. The telescopic spring 74 rebounds, causing the ejection frame 73 to spread the desiccant evenly on the isolation frame 71. This achieves the effect of absorbing the condensation through the desiccant, effectively preventing the condensation from causing a short circuit to the photovoltaic energy storage transformer 3, and facilitating the replacement of the desiccant.
