Description

Technical Field

[0001] The present application relates to the technical field of photovoltaic power supply, and in particular to a photovoltaic power supply device with an intelligent control box. Background Art

[0002] In places where power cannot be supplied by the grid, one of the power supply options for electrical equipment is photovoltaic power supply, that is, powering electrical equipment through solar panels, batteries and control systems. However, in the existing power supply method, the battery and the control system are installed in the same box. Generally, considering the center of gravity, the battery is usually installed at the bottom, so the control system is also located at the bottom, which makes it inconvenient to maintain the control system. Summary of the invention

[0003] In view of the deficiencies in the prior art, one of the purposes of the present application is to provide a photovoltaic power supply device with an intelligent control box, which has the advantage of facilitating maintenance of the control system.

[0004] The above-mentioned purpose of the present application is achieved through the following technical solutions:

[0005] A photovoltaic power supply device with an intelligent control box comprises a support base, a control box and a power box. The power box is arranged at the bottom of the support base, and the control box is arranged in the middle of the support base or in a position facing upward from the middle. The power box is used to place batteries, and the control box is used to place a control system.

[0006] By adopting the above technical solution, during use, since the control system is placed in the control box, and the control box and the power box are separated, and the control box is in the middle or middle-upward position of the support base, the operator does not need to bend over or squat to inspect the control system, thereby facilitating maintenance of the control system.

[0007] In a preferred example, the present application can be further configured as follows: a accommodating cavity is provided on the support base, the accommodating cavity is used to place a key for opening the control box and / or the power box, a blocking door is also provided on the support base for sealing the accommodating cavity, and a detection module is provided in the accommodating cavity for detecting the state of the blocking door.

[0008] By adopting the above technical solution, since the key is placed in the accommodating cavity, the maintenance personnel do not need to carry the key, which is more convenient.

[0009] In a preferred example, the present application can be further configured as follows: a collection module is also provided on the support seat, and after the detection module detects that the blocking door is opened, it sends an opening signal to the control system, and after the control system receives the opening signal, it sends a collection signal to the collection module, and the collection module performs data collection and transmits the collected data to the main control console.

[0010] By adopting the above technical solution, when the blocking door is opened, information is collected and sent to the main control console so that the operator at the main control console can make judgments on the collected information.

[0011] In a preferred example, the present application can be further configured as follows: after receiving the opening signal, the control system determines whether the inspection signal is received. If the inspection signal is received, the control system sends a collection signal to the collection module, the collection module performs data collection, and transmits the collected data to the main control console; if the inspection signal is not received, the control system sends a collection signal to the collection module, the collection module performs data collection, and transmits the collected data and abnormal signals to the main control console.

[0012] By adopting the above technical solution, that is, when the inspection signal is received, the blocking door is opened for a normal maintenance process; if no inspection signal is received, it is a non-maintenance process, and the collected information and abnormal quotes are transmitted to the main control station. After receiving the abnormal signal, the main control station will increase its attention and make timely judgments on the collected information.

[0013] In a preferred example, the present application can be further configured as follows: the detection module is also used to detect whether there is a key in the control box. After the detection module detects that the blocking door is closed, it sends a closing signal to the control module. After the control module receives the closing signal, it detects whether there is a key in the control box through the detection module. If there is no key, it sends a non-reset signal to the control system. After the control system receives the non-reset signal, it sends a placement signal to the main control console, and the main control console prompts the operator.

[0014] By adopting the above technical solution, when the blocking door is closed, the key is detected, but if the key is not detected, the operator (maintenance personnel) is prompted through the main control console, thereby avoiding the probability of the key being lost or taken away.

[0015] In a preferred example, the present application can be further configured as follows: the detection module includes conductor one and conductor two, conductor one and conductor two are used to clamp the key, and whether the key is taken is determined by the on-off of the circuit where conductor one and conductor two are located.

[0016] By adopting the above technical solution, when in use, the key is clamped by conductor one and conductor two, so that the purpose of fixing the key can be achieved. At the same time, by the on-off of the circuit where the blade body one and conductor two are located, it is judged whether the key is taken away, so that the judgment is more accurate. DETAILED DESCRIPTION

[0017] The present application discloses a photovoltaic power supply device with an intelligent control box, including a support base, a control box and a power box. The power box is arranged at the bottom of the support base, and the control box is arranged in the middle of the support base or in a position upward from the middle. The power box is used to place batteries, and the control box is used to place a control system. The support base is provided with a receiving cavity, and the receiving cavity is used to place a key for opening the control box and / or the power box. The support base is also provided with a blocking door for blocking the receiving cavity, and a detection module for detecting the state of the blocking door is provided in the receiving cavity. In actual use, the receiving cavity and the blocking door can be concealed, for example, the receiving cavity is opened at a position on the support base that is not easily discovered, and the blocking door and the support base are set in the same color, etc.

[0018] The support seat is also provided with a collection module. After the detection module detects that the blocking door is opened, it sends an opening signal to the control system. After receiving the opening signal, the control system sends a collection signal to the collection module. The collection module collects data and transmits the collected data to the main control console. In this embodiment, in order to reduce costs, when the electrical device is a camera, the electrical device can be used as an image acquisition component of the collection module. If the electrical device does not have functions such as data acquisition and image acquisition, the collection module may include a camera.

[0019] After receiving the opening signal, the control system determines whether the inspection signal is received. If the inspection signal is received, the control system sends a collection signal to the collection module, the collection module performs data collection, and transmits the collected data to the main control console. If the inspection signal is not received, the control system sends a collection signal to the collection module, the collection module performs data collection, and transmits the collected data and abnormal signals to the main control console.

[0020] The detection module is also used to detect whether there is a key in the control box. After the detection module detects that the blocking door is closed, it sends a closing signal to the control module. After receiving the closing signal, the control module detects whether there is a key in the control box through the detection module. If there is no key, it sends a non-reset signal to the control system. After receiving the non-reset signal, the control system sends a placement signal to the main control console, and the main control console prompts the operator.

[0021] In this embodiment, the blocking door and the support seat are hinged, a fixed ring is provided in the accommodating cavity, and a sliding rod is passed through the fixed ring. The sliding rod can move along the axial direction of the fixed ring. Conductor 1, conductor 2, an electromagnet and a battery are also provided in the accommodating cavity. The positive pole of the battery is connected to conductor 1, and the negative pole is connected to conductor 2, which is used to power the electromagnet. In this embodiment, the battery is a low-voltage battery, such as 1.5V, 3V or 6V, etc. A magnet is provided at one end of the sliding rod close to the electromagnet.

[0022] Conductor 1 and conductor 2 are metal sheets for clamping the key, and an insulating layer is provided on the key. When the key is removed, since conductor 1 and conductor 2 are both made of metal (such as copper), conductor 1 and conductor 2 are in contact, the circuit is turned on, the electromagnet is energized, and the polarity of the end of the electromagnet close to the sliding rod is the same as the polarity of the end of the magnet on the sliding rod close to the electromagnet, so that the sliding rod moves away from the electromagnet and moves to the moving path of the blocking door. That is, when the key is removed, there is resistance to closing the blocking door, which can reduce the probability of maintenance personnel taking the key away after closing the blocking door by mistake.

[0023] The implementation principle of this embodiment is: in use, by setting the power supply and the control system separately, it is convenient for maintenance personnel to maintain the control system, and at the same time, the key is set in the accommodating cavity on the support base, thereby greatly reducing the probability of loss of the key caused by the maintenance personnel carrying it.

[0024] The embodiments of this specific implementation method are all preferred embodiments of the present application, and are not intended to limit the protection scope of the present application. Therefore, all equivalent changes made based on the structure, shape, and principle of the present application should be included in the protection scope of the present application.
