Description

Technical Field

[0001] The invention relates to the technical field of distribution station equipment, and in particular to an inverter box used in a distribution station. Background Art

[0002] An inverter is an electronic device that converts low voltage (12 or 24 volts) direct current into 220 volts alternating current. Because we usually rectify 220 volts alternating current into direct current for use, and the inverter does the opposite, hence the name. As an important component of a distribution station, the inverter is usually placed in an inverter box, which protects it. The current inverter box mainly protects the inverter from external influences.

[0003] With the vigorous development of my country's electricity, distribution stations are gradually spread all over the country. Due to my country's vast geography and complex terrain, the inverter boxes in distribution stations need to protect the inverters in various environments. For example, in mountainous areas, when encountering strong winds, the shielding components used for protection are moved and attached to the heat dissipation components by the wind, causing the heat dissipation components to be sealed, affecting the working effect of the heat dissipation components, and then easily causing the working environment temperature of the components inside the box to be too high, affecting the normal service life of the components inside the box. When encountering rainy and snowy weather, rainwater enters the box through the heat dissipation components, which easily causes the components inside the box to be damp and damaged. Summary of the invention

[0004] The object of the present invention is to provide an inverter box for use in a power distribution station which is not affected by external influences, can dissipate heat normally, and is not easily affected by moisture.

[0005] The present invention is achieved through the following technical scheme: an inverter box used in a distribution station, the bottom plate, an inverter box body is connected above the bottom plate, an air outlet is arranged on one side of the inverter box body, a heat dissipation mechanism is connected on the side wall of the inverter box body and located at the periphery of the air outlet, a protective component is arranged above the heat dissipation mechanism, a shielding mechanism is arranged on the side of the heat dissipation mechanism away from the air outlet, a supporting component is arranged between the shielding mechanism and the heat dissipation mechanism, and a baffle is connected above the inverter box body.

[0006] In order to better realize the present invention, further, the support assembly includes a cavity, a rotating shaft, a support rod and a fixing part, a cavity is arranged below the heat dissipation mechanism, a support rod is arranged inside the cavity, a rotating shaft is connected between the cavity and the support rod, and a fixing part is arranged between the shielding mechanism and the support rod.

[0007] In order to better realize the present invention, further, the fixing part includes a second threaded cylinder, a circular hole, a fixing block and a fixing bolt. A fixing block is connected on the side wall of the shielding mechanism and located above the support rod. Circular holes are provided on the support rod and the fixing block. A fixing bolt is inserted into the inside of one of the circular holes, and a second threaded cylinder is connected to the inside of the other circular hole and located on the outer side wall of the fixing bolt.

[0008] In order to better implement the present invention, further, a plug-in cavity is provided on the side wall of the heat dissipation mechanism at a position corresponding to the fixing block, and a rubber pad is connected to the inner side wall of the plug-in cavity.

[0009] In order to better realize the present invention, further, the protective component includes a protective cover, a movable cavity, a fixed screw, a movable plate, a first threaded barrel, a through hole and a magnetic ring. A protective cover is arranged on the upper periphery of the heat dissipation mechanism, and a movable plate is connected to a side of the protective cover close to the heat dissipation mechanism, a movable cavity is arranged on the side wall of the heat dissipation mechanism and at a position corresponding to the movable plate, a fixed screw is connected to the side wall of the movable plate, a through hole is arranged at one end of the protective cover, a first threaded barrel is inserted into the inside of the through hole, and a magnetic ring is connected to the side where the first threaded barrel and the protective cover are close to each other.

[0010] In order to better implement the present invention, further, a guide slide block is connected to the inner side wall of the protective cover, and a guide groove is provided on the outer side wall of the heat dissipation mechanism at a position corresponding to the guide slide block.

[0011] Compared with the prior art, the present invention has the following advantages and beneficial effects: (1) The present invention sets a support assembly. After the shielding mechanism is pulled away from the heat dissipation mechanism, the support rod is rotated under the action of the rotating shaft. When the support rod and the fixed block are in a parallel state, the fixing bolt and the second threaded cylinder are manually inserted into the two circular holes respectively, and the second threaded cylinder is rotated so that it is threadedly connected to the fixing bolt. Under the action of the fixing bolt and the second threaded cylinder, the support rod and the fixed block can be fixed, and then the shielding mechanism can be supported and fixed, thereby ensuring the stability of the placement of the shielding mechanism and preventing the shielding mechanism from being moved to fit the side wall of the heat dissipation mechanism under the action of wind force, thereby affecting the heat dissipation effect of the heat dissipation mechanism. (2) The present invention sets a protective component. After the shielding mechanism is fixed, the first threaded cylinder is pulled out from the inside of the perforation, so that the first threaded cylinder and the magnetic ring on the protective cover are separated, and then the protective cover is moved. The movement of the protective cover drives the moving plate to move inside the moving cavity. The movement of the moving plate drives the fixed screw to move through the perforation, and then the protective cover is pressed. Then, the first threaded cylinder is manually rotated and screwed onto the fixed screw. The moving plate is fixed by the first threaded cylinder and the fixed screw, so that the protective cover can be fixed. Under the action of the protective cover, rain and snow in the external environment can be prevented from entering the interior of the inverter box through the heat dissipation mechanism during subsequent use, causing the components inside the inverter box to be damaged by moisture; (3) The present invention improves the structure of the existing inverter box to protect the inverter, so that it can adapt to harsh environments and extreme weather. While ensuring the heat dissipation effect, it also has a moisture-proof function, provides a stable environment for the normal operation of the inverter, ensures the normal use of electricity, and is suitable for wide promotion and application.

[0018] The specific implementation method is to install the base plate 3 to the photovoltaic power station site, so that the inverter box body 4 can be fixed, and then the shielding mechanism 1 is pulled to keep it away from the heat dissipation mechanism 2, and then the shielding mechanism 1 is supported and fixed by the support assembly 8 to ensure the stability of the placement of the shielding mechanism 1, so as to avoid that when the base plate 3 is installed in a high mountain location and the wind is strong on the mountain, the shielding mechanism 1 is moved to fit the side wall of the heat dissipation mechanism 2 by the wind, thereby affecting the heat dissipation effect of the heat dissipation mechanism 2, and then the heat dissipation mechanism 2 is started, and the heat dissipation mechanism 2 is used to perform heat dissipation operation on the inside of the inverter box body 4, so as to ensure that the internal ambient temperature of the inverter box body 4 is in a normal state, thereby ensuring the normal operation of the internal components of the inverter box body 4.

[0019] Embodiment 2: Based on the above embodiment, this embodiment further defines the structure of the support assembly 8, such as Figure 4 As shown, the support assembly 8 includes a cavity 81, a rotating shaft 82, a support rod 83 and a fixing member 84. The cavity 81 is provided below the heat dissipation mechanism 2, and the support rod 83 is provided inside the cavity 81. The rotating shaft 82 is connected between the cavity 81 and the support rod 83, and the fixing member 84 is provided between the shielding mechanism 1 and the support rod 83. By adopting the above technical solution, after the shielding mechanism 1 is opened, the support rod 83 is rotated under the action of the rotating shaft 82. When the support rod 83 is parallel to the fixing member 84, the fixing member 84 is used to support and fix the support rod 83 and the shielding mechanism 1, so as to ensure the stability of the placement of the shielding mechanism 1 and avoid the shielding mechanism 1 being forced to fit the side wall of the heat dissipation mechanism 2, thereby affecting the heat dissipation effect of the heat dissipation mechanism 2.

The fixing block 843 is connected to the side wall of the shielding mechanism 1 and located above the support rod 83. The support rod 83 and the fixing block 843 are both provided with circular holes 842. The fixing bolt 844 is inserted into one of the circular holes 842, and the second threaded cylinder 841 is connected to the other circular hole 842 and located on the outer side wall of the fixing bolt 844.

[0021] Embodiment 4: Based on the above embodiment, this embodiment further defines the structure of the support assembly 8, such as Figure 4As shown, a plug-in cavity 85 is provided on the side wall of the heat dissipation mechanism 2 and at the position corresponding to the fixed block 843, and a rubber pad is connected to the inner wall of the plug-in cavity 85. When the shielding mechanism 1 is not needed, the shielding mechanism 1 is moved toward the heat dissipation mechanism 2, and the movement of the shielding mechanism 1 drives the fixed block 843 to move and plug into the plug-in cavity 85, so as to prevent the fixed block 843 from affecting the shielding effect of the shielding mechanism 1 on the heat dissipation mechanism 2, and under the action of the rubber pad, the friction between the fixed block 843 and the plug-in cavity 85 can be increased, thereby improving the plug-in stability of the fixed block 843. The other parts of this embodiment are the same as the above embodiment and will not be repeated.

[0022] Embodiment 5: Based on the above embodiment, this embodiment further defines the structure of the protection component 6, such as Figures 5 to 7 As shown, the protective component 6 includes a protective cover 61, a movable cavity 62, a fixed screw 63, a movable plate 64, a first threaded barrel 65, a through hole 66 and a magnetic ring 67. The protective cover 61 is arranged on the upper periphery of the heat dissipation mechanism 2, and the movable plate 64 is connected to the side of the protective cover 61 close to the heat dissipation mechanism 2, and a movable cavity 62 is arranged on the side wall of the heat dissipation mechanism 2 at a position corresponding to the movable plate 64, and a fixed screw 63 is connected to the side wall of the movable plate 64. A through hole 66 is arranged at one end of the protective cover 61, and the first threaded barrel 65 is inserted into the inside of the through hole 66, and the first threaded barrel 65 and the protective cover 61 are connected to the magnetic ring 67 on the side close to each other. After the shielding mechanism 1 is fixed, the first threaded barrel 65 is pulled out from the inside of the perforation 66, so that the first threaded barrel 65 and the magnetic ring 67 on the protective cover 61 are separated, and then the protective cover 61 is moved. The movement of the protective cover 61 drives the moving plate 64 to move inside the moving cavity 62, and the movement of the moving plate 64 drives the fixing screw 63 to move through the perforation 66, and then the protective cover 61 is pressed, and then the first threaded barrel 65 is manually rotated and screwed onto the fixing screw 63, and the first threaded barrel 65 and the fixing screw 63 are used to fix the moving plate 64, so that the protective cover 61 can be fixed. Under the action of the protective cover 61, rain and snow in the external environment can be prevented from entering the interior of the inverter box body 4 through the heat dissipation mechanism 2 during subsequent use, causing the components inside the inverter box body 4 to be damaged by moisture. The other parts of this embodiment are the same as the above embodiment and will not be repeated.

[0023] Embodiment 6: Based on the above embodiment, this embodiment further defines the structure of the protection component 6, such as Figures 5 to 7As shown, a guide slider is connected to the inner side wall of the protective cover 61, and a guide slot is provided on the outer side wall of the heat dissipation mechanism 2 at a position corresponding to the guide slider. By adopting the above technical solution, the movement of the protective cover 61 drives the guide slider to move inside the guide slot. Under the sliding cooperation of the guide slider and the guide slot, a guiding effect can be provided for the movement of the protective cover 61, thereby improving the stability of the movement of the protective cover 61. The other parts of this embodiment are the same as those of the above embodiment and will not be described in detail.

[0024] It can be understood that according to the inverter box structure of an embodiment of the present invention, for example, the structure and principle of the shielding mechanism 1 composed of a blocking ring, a connecting rod, a fixing plate, and a handle, and the working principle and working process of the heat dissipation mechanism 2 composed of a connecting plate, an exhaust box, a protective frame, a filter, an exhaust fan, and a fixing bolt are all prior arts and are well known to technicians in this field. The working principle of the shielding mechanism 1 is that a connecting rod is inserted into the interior of the heat dissipation mechanism 2, and the end of the connecting rod close to the heat dissipation mechanism 2 is connected to a blocking ring, and the other end of the connecting rod is connected to a fixing plate, and a handle is connected to the side wall of the fixing plate. When in use, when the heat dissipation mechanism 2 or the device is in an idle state, the fixing plate is pushed to move in the direction of the heat dissipation mechanism 2 by holding the handle, and then the fixing plate is blocked at the front end of the heat dissipation mechanism 2. At this time, the fixing plate plays a shielding role on the heat dissipation mechanism 2, which can effectively prevent external dust and impurities from entering the inverter box body 4 through the heat dissipation mechanism 2. At the same time, when the heat dissipation mechanism 2 needs to be used, the handle can be first held to apply force to drive the fixing plate to move away from the heat dissipation mechanism 2, thereby ensuring the normal use effect of the heat dissipation mechanism 2. The working principle of the heat dissipation mechanism 2 is that a connecting plate is connected to one side of the inverter box body 4 and located at the periphery of the air outlet 7, and the connecting plate and the inverter box body 4 are connected by fixing bolts, and an exhaust box is connected to one side of the connecting plate, and the exhaust box is connected to an exhaust fan inside, and a protective frame is connected to the inside of the exhaust box and located on one side of the exhaust fan, and a filter is connected to the inside of the protective frame. When in use, when it is necessary to actively dissipate the heat of the inside of the inverter box body 4, the exhaust fan is first electrically connected to the external power supply, and then under the action of electricity, the exhaust fan starts to rotate and extracts the heat from the inside of the inverter box body 4, and the heat inside the inverter box body 4 is first drawn into the exhaust box through the air intake port at the connecting plate, and then discharged to the outside through the filter, which will not be described in detail here.
