Description

Technical Field

[0001] This utility model relates to the field of photovoltaic controller technology, and in particular to a parallel photovoltaic controller. Background Technology

[0002] A parallel photovoltaic controller is a device used in solar photovoltaic power generation systems. It is mainly used to manage the charging process between solar panels and batteries. Unlike series controllers, parallel photovoltaic controllers connect solar panels to batteries in parallel during operation, thereby controlling the charging current and voltage to prevent overcharging or over-discharging of batteries.

[0003] The existing announcement number CN205160461U, entitled "An Intelligent Photovoltaic Combiner Control Box," includes a photovoltaic array, a photovoltaic combiner, a controller, a DC distributor, an AC distribution cabinet, a photovoltaic inverter, and two or more photovoltaic arrays connected in parallel to the photovoltaic combiner. After current is combined within the photovoltaic combiner, the controller, the DC distributor, the photovoltaic inverter, and the AC distribution cabinet work together to form a complete photovoltaic power generation system. This utility model connects a certain number of photovoltaic cells of the same specifications in series to form photovoltaic arrays, and then connects several photovoltaic arrays in parallel to the photovoltaic combiner. After current is combined within the combiner box, the controller, the DC distributor, the photovoltaic inverter, and the AC distribution cabinet work together to form a complete photovoltaic power generation system, enabling grid connection with residential users.

[0004] However, the aforementioned photovoltaic controllers typically require multiple photovoltaic arrays to be connected in parallel. Therefore, the photovoltaic controllers will be connected to multiple sets of cables. However, the aforementioned photovoltaic controller chassis lacks cable support components, which causes the photovoltaic controller chassis connection cables to be directly run through the photovoltaic controller chassis. Multiple cables are scattered, which is not conducive to improving the stability of the cables running through the photovoltaic controller chassis and affects the stability of the cable connection of the photovoltaic controller chassis. Utility Model Content

[0005] This invention solves the problems in related technologies and proposes a parallel photovoltaic controller.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: a parallel photovoltaic controller, including a control box, an opening on the front end of the control box, and a door rotatably connected to the opening of the control box. Guide plates are fixed through the upper and lower end faces of the control box. Multiple controllers are horizontally fixed on the lower side of the inside of the control box, and an inverter is horizontally fixed on the upper side of the inside of the control box. A wire component is provided on the rear end face of the control box. The wire component includes a wire frame, which is fixed on the rear end face of the control box. Both the upper and lower ends of the wire frame are horizontally clamped with plates. Both the upper and lower ends of the wire frame are horizontally provided with movable clamps. Multiple wire clamping arc plates are horizontally fixed between the movable clamps and the clamps. Guide posts are vertically fixed on both sides of the horizontal end face of the movable clamps near the clamps. The guide posts are slidably inserted through the clamps. Wire clamping springs are vertically sleeved on the guide posts, and the two ends of the wire clamping springs are respectively fixed to the top of the guide post and the clamps.

[0007] As a preferred embodiment, cables are held between the movable clamps, and the cables on the lower side of the movable clamps extend through the bottom guide plate to the inside of the control box.

[0008] As a preferred embodiment, the movable clamp and the cable on the lower side of the clamp are connected to the controller input terminal, and the controller output terminal is electrically connected to the inverter input terminal. The inverter output terminal is electrically connected to a cable, and the cable connected to the inverter output terminal extends from the top guide plate to the outside of the control box. The cable connected to the inverter output terminal is clamped between the movable clamp and the clamp on the upper side of the conductor frame.

[0009] As a preferred option, wire guide plates are horizontally fixed on both the upper and lower sides of the control box, and the wire guide plates are used for cable routing.

[0010] As a preferred embodiment, wire clamps are provided on both the upper and lower end faces of the control box. The wire clamps include a wire clamp frame and a wire support plate. The wire frame is vertically fixed on the control box, and the wire clamp frame has a horizontally arranged wire support plate.

[0011] As a preferred embodiment, a sliding rod is vertically fixed on the cable support plate, and the sliding rod slides vertically through the cable clamping frame. Multiple cable clamping slots are horizontally fixed on the adjacent horizontal end faces of the cable support plate and the cable clamping frame, and the cable support plate and the cable clamping frame are used to clamp the cable.

[0012] As a preferred embodiment, a support spring is vertically fixed on the wire clamp, and the two ends of the support spring are fixed to the wire clamp and the slide rod respectively.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: During use, the external cable passes through and is inserted between the moving clamps at the bottom of the wire frame in the wire component at the rear of the control box. The cable is pushed by the deformation force of the clamping spring on the guide post of the moving clamp, so that multiple clamping arc plates are horizontally fixed between the moving clamps and the clamps. The cable is then guided into the control box through the guide hole plate on the bottom surface of the control box. The cable is first connected to the controller, then connected to the inverter, and multiple cables are connected to the inverter. Then, multiple cables pass through and are inserted between the moving clamps at the top of the wire frame in the wire component at the rear of the control box. Thus, the cable is guided and clamped by the wire component, maintaining the stability of the cable connection. The organized cable is easier to find later, which helps to improve the stability of the cable installation in the photovoltaic controller box. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the present utility model or its application or use. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0021] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0022] Unless otherwise specifically stated, the relative arrangement, numerical expressions, and values ​​of the components and steps described in these embodiments do not limit the scope of this invention. It should also be understood that, for ease of description, the dimensions of the various parts shown in the drawings are not drawn to actual scale. Techniques, methods, and devices known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and devices should be considered part of the specification. In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters in the following drawings denote similar items; therefore, once an item is defined in one drawing, it need not be further discussed in subsequent drawings.

[0023] In the description of this utility model, it should be understood that the directional terms such as "front, back, up, down, left, right", "horizontal, vertical, horizontal" and "top, bottom" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description. Unless otherwise stated, these directional terms do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the scope of protection of this utility model. The directional terms "inner" and "outer" refer to the inner and outer contours of each component itself.

[0024] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures.

Unless otherwise stated, the above terms have no special meaning and therefore cannot be construed as limiting the scope of protection of this utility model.

[0026] like Figures 1 to 5As shown, a parallel photovoltaic controller includes a control box 1. The front end of the control box 1 is open, and a door 11 is rotatably connected to the opening. Guide plates 12 are fixed through the upper and lower ends of the control box 1. Multiple controllers 2 are horizontally fixed on the lower side of the interior of the control box 1, and an inverter 3 is horizontally fixed on the upper side of the interior of the control box 1. A wire component 4 is provided on the rear end of the control box 1. The wire component 4 includes a wire frame 41, which is fixed to the rear end of the control box 1. Both the upper and lower ends of the wire frame 41 are horizontally clamped with plates 42. Both the upper and lower ends of the wire frame 41 are horizontally provided with movable clamps 43. Multiple wire clamping arc plates 44 are horizontally fixed between the movable clamps 43 and the clamps 42. Guide posts 45 are vertically fixed on both sides of the horizontal end face of the movable clamps 43 near the clamps 42. The guide posts 45 are slidably inserted into the clamps 42. A wire clamping spring 46 is vertically sleeved on the guide post 45. The two ends of the wire spring 46 are fixed to the top of the guide post 45 and the clamping plate 42 respectively. During use, the external cable passes through the bottom of the wire frame 41 in the wire fitting 4 on the rear side of the control box 1 between the moving clamping plate 43 and the clamping plate 42. The cable is pushed by the deformation force of the wire clamping spring 46 on the guide post 45 of the moving clamping plate 43, so that multiple wire clamping arc plates 44 are horizontally fixed between the moving clamping plate 43 and the clamping plate 42. The cable is guided into the inside of the control box 1 through the guide hole plate 12 on the bottom surface of the control box 1. The cable is first connected to the controller 2, and then connected to the inverter 3. Multiple cables are connected to the inverter 3. Then, multiple cables pass through the top of the wire frame 41 in the wire fitting 4 on the rear side of the control box 1 between the moving clamping plate 43 and the clamping plate 42. Thus, the cable is guided and clamped by the wire fitting 4, maintaining the stability of the cable connection. The organized cable is easy to find later and helps to improve the stability of the cable installation in the photovoltaic controller box.

[0027] In one embodiment, such as Figure 3 and Figure 5As shown, cables are clamped between the movable clamping plate 43 and the clamping plate 42. Cables on the lower sides of the movable clamping plates 43 and 42 extend through the bottom guide plate 12 to the interior of the control box 1. The cables on the lower sides of the movable clamping plates 43 and 42 are connected to the input terminal of the controller 2. The output terminal of the controller 2 is electrically connected to the input terminal of the inverter 3. Cables are electrically connected to the output terminal of the inverter 3. The cables connected to the output terminal of the inverter 3 extend from the top guide plate 12 to the outside of the control box 1. The cable is held between the movable clamp 43 and the clamp 42 on the upper side of the conductor frame 41. The upper and lower sides of the control box 1 are both horizontally fixed with wire hole plates 13, which are used to pass through the cables. In use, the cables are guided into the control box 1 through the guide plate 12 on the bottom surface of the control box 1. The cables are first connected to the controller 2, and then connected to the inverter 3. Multiple cables are connected to the inverter 3. Then, the multiple cables pass through and are inserted from the conductor frame 41 at the rear of the control box 1 between the movable clamp 43 and the clamp 42.

[0028] In one embodiment, such as Figure 3 and Figure 4 As shown, cable clamps 5 are provided on both the upper and lower end faces of the control box 1. The cable clamps 5 include a cable clamp frame 51 and a cable support plate 52.

A sliding rod 54 is vertically fixed on the cable support plate 52, and the sliding rod 54 is vertically slidably assembled on the cable clamp frame 51. Multiple cable clamping slots 53 are horizontally fixed on the adjacent horizontal end faces of the cable support plate 52 and the cable clamp frame 51. The cable support plate 52 and the cable clamp frame 51 are used to clamp cables. A support spring 55 is vertically fixed on the wire clamp 51, and the two ends of the support spring 55 are respectively fixed on the wire clamp 51 and the slide bar 54. During use, the cable passes through the wire clamp 51 and the cable support plate 52 at the bottom of the wire frame 41 in the wire clamp 5 on the control box 1. The cable is pushed by the deformation force of the support spring 55 on the slide bar 54 of the cable support plate 52, so that multiple wire clamping slots 53 are horizontally fixed between the wire clamp 51 and the cable support plate 52 to hold and fix the cable, ensuring the stability of the cable.

[0029] In this embodiment, the external cable is inserted through the bottom moving clamp 43 and clamp 42 of the wire frame 41 in the wire component 4 on the rear side of the control box 1. The cable is pushed by the deformation force of the clamping spring 46 on the guide post 45 of the moving clamp 43, so that multiple clamping arc plates 44 are horizontally fixed between the moving clamp 43 and the clamp 42. The cable is guided into the inside of the control box 1 through the guide hole plate 12 on the bottom surface of the control box 1. The cable is first connected to the controller 2, and then connected to the inverter 3. Multiple cables are connected to the inverter 3. Then, multiple cables are inserted through the top moving clamp 43 and clamp 42 of the wire frame 41 in the wire component 4 on the rear side of the control box 1.
