Description

Technical Field

[0001] This utility model belongs to the field of power supply technology, and in particular to a solar power supply device. Background Technology

[0002] Many existing traffic monitoring devices or other monitoring equipment have the following installation methods: 1. The monitoring equipment has its own battery. After the battery is fully charged, it can guarantee the use of the monitoring equipment for a certain period of time. When the battery is depleted, personnel need to replace the battery of the monitoring equipment; 2. The monitoring equipment is directly connected to the mains power after it is installed; 3. A solar panel and a battery are installed on the monitoring equipment. The solar panel charges the battery, and the battery powers the monitoring equipment.

[0003] The three installation methods described above have the following drawbacks: First, the monitoring equipment requires battery replacement at regular intervals, which is very inconvenient. Second, the monitoring equipment is connected to mains power, making installation extremely difficult, especially in remote areas or waterways, where connection to mains power is cumbersome and inconvenient to operate. Third, due to the shape of the monitoring equipment, solar panels are typically only installed on one outer surface. These solar panels are relatively small, resulting in poor battery charging efficiency, and sunlight may not reach them all day, posing a risk to the equipment's battery life. Utility Model Content

[0004] The purpose of this invention is to address the aforementioned problems in existing technologies by proposing a solar power supply device. The technical problem this invention aims to solve is: how to resolve the issues of inconvenient power connection and poor battery life of existing monitoring equipment after installation.

[0005] The objective of this utility model can be achieved through the following technical solutions:

[0006] A solar power supply device includes a transparent housing with an opening at one end and an end cap that closes the opening at the other end. The housing is rectangular with a rectangular cavity. Solar panels are disposed on the four inner sidewalls and one bottom surface of the rectangular cavity. A battery module and a control circuit board are disposed within the housing. The battery module and all solar panels are electrically connected to the control circuit board. A positive and a negative wire are connected to the control circuit board, penetrating the housing and extending outside the housing.

[0007] The device is specially used for supplying power to outdoor monitoring equipment or other monitoring equipment. Four inner side walls and a bottom surface of the rectangular cavity of the structure shell are provided with solar panels. This ensures that at least one solar panel can be irradiated by sunlight, ensuring that the battery module can be charged. When two or more solar panels are irradiated by sunlight, the charging efficiency of the battery module is improved. The positive and negative leads extend from the shell to the outside of the shell. The positive and negative leads are equivalent to two power lines, which facilitates the connection of the device with the equipment and supplies power to the equipment. The device can supply power to various outdoor equipment as a single power supply device. The device has a large battery capacity, strong power supply performance, and good charging efficiency, which avoids the occurrence of battery module power feeding and ensures the normal operation of the equipment.

[0008] In the above-mentioned solar power supply device, four corners of the bottom surface of the rectangular cavity are provided with right-angle corner codes. The right-angle corner codes and the inner side walls of the rectangular cavity form limiting grooves. The lower ends of the four solar panels corresponding to the four inner side walls of the rectangular cavity are inserted into the corresponding limiting grooves. The right-angle corner codes facilitate the installation and positioning of the solar panels and prevent the solar panels from falling over.

[0009] In the above-mentioned solar power supply device, the inner side wall of the end cover has a rectangular boss protruding towards the inside of the shell. The four outer side walls of the rectangular boss abut against the corresponding solar panels. The rectangular boss plays a role in positioning the solar panels, ensuring that the solar panels are installed stably and do not fall over.

[0010] In the above-mentioned solar power supply device, the rectangular boss has a battery cavity and a circuit board mounting cavity. The battery module is arranged in the battery cavity, and the control circuit board is arranged in the circuit board mounting cavity.

[0011] In the above-mentioned solar power supply device, the inner side wall of the end cover has a glue injection cavity. Two through holes are formed in the inner wall of the glue injection cavity. The positive lead wire extends to the outside of the end cover through one of the through holes, and the negative lead wire extends to the outside of the end cover through the other through hole. The glue injection cavity is filled with waterproof glue. After the waterproof glue hardens, it completely blocks the two through holes, making the entire device in a completely closed state, improving the waterproof performance of the entire device.

[0012] In the above-mentioned solar power supply device, the outer periphery of the rectangular boss is provided with a rectangular fence. The rectangular fence and the rectangular boss form a rectangular positioning groove. The ends of the solar panels on the four inner side walls of the rectangular cavity are respectively inserted into the positioning grooves. The positioning grooves position the ends of the solar panels, ensuring that the solar panels are installed stably and do not fall over.

[0013] In the solar power supply device, the solar cell panel on the inner bottom surface of the rectangular cavity is located at the inner side of the four right-angle corner codes and abuts against the four right-angle corner codes.

[0014] In the solar power supply device, the open end of the shell has a flange, the outer edge of the flange is provided with a surrounding edge perpendicular to the flange, the end cover is embedded in the surrounding edge and abuts against the flange, and a sealing ring is arranged between the end cover and the flange.

[0015] Compared with the prior art, the solar power supply device has the following advantages: the device can supply power to various outdoor installed equipment as a single power supply device, has a large battery capacity, has strong power supply performance, has good charging efficiency, avoids the occurrence of power feeding of the battery module, and ensures the normal operation of the equipment.
