Description

Technical Field

[0001] This utility model relates to the field of photovoltaic power generation technology, and in particular to photovoltaic collector collection equipment. Background Technology

[0002] In photovoltaic power generation systems, photovoltaic combiner boxes are important devices for collecting, monitoring, and protecting the output current of multiple photovoltaic arrays.

[0003] Existing photovoltaic combiner boxes have the following problems: First, the internal wiring layout is messy, making it difficult to quickly locate the problematic line during line maintenance and troubleshooting, resulting in low maintenance efficiency; Second, the heat dissipation performance is poor, and the heat generated by the internal electronic components accumulates after long-term operation, which can easily lead to accelerated component aging and affect the service life of the equipment; Third, there is a lack of effective waterproof and moisture-proof structure, and in harsh weather conditions, moisture can easily enter the box, causing short circuits and other malfunctions. Utility Model Content

[0004] To overcome the existing problems, this application provides a photovoltaic combiner acquisition device to solve the problems of messy and difficult-to-maintain wiring, poor heat dissipation, and insufficient waterproof and moisture-proof performance of existing photovoltaic combiner boxes.

[0005] The technical solution adopted by the embodiments of this application to solve its technical problem is:

[0006] A photovoltaic combiner collection device includes a housing with a cover on one side. The cover is hinged to the top of the housing for sealing the housing. A mounting bracket is provided on the back of the housing for fixing the housing. The housing is made of metal and has good strength and protective performance. The cover is hinged to the top of the housing by a hinge and can be rotated around the hinge to open or close.

[0007] The enclosure is equipped with a wiring management component, including multiple partitions and a mounting bracket. The partitions divide the interior of the enclosure into multiple independent wiring channels, and the mounting bracket is installed on one side of the partitions to fix electrical components.

[0008] The box body is provided with a moisture-proof strip at the intersection of the box body and the box cover. The box body is provided with a moisture-proof board on the side near the moisture-proof strip. The moisture-proof board and the box body are detachable. When the box cover is closed, the box cover and the box body fit together and squeeze the moisture-proof strip, so that the moisture-proof strip and the box cover fit tightly with the box body to form a sealed structure and prevent moisture from entering from the gaps.

[0009] Preferably, the housing has heat dissipation holes at the corresponding positions of the moisture-proof board, and dustproof nets are installed at the heat dissipation holes to prevent dust from entering the housing. When the temperature inside the housing rises, hot air is discharged from the heat dissipation holes to achieve heat dissipation. The dustproof nets can block dust and prevent dust from entering the housing and affecting the operation of the equipment. The heat dissipation holes have a downward sloping structure, and the moisture-proof board is made of a material with good moisture-proof performance, such as moisture-proof cardboard, and is laid inside the housing on one side of the heat dissipation holes to absorb any small amount of moisture that may enter.

[0010] Preferably, the bottom of the enclosure is provided with multiple connectors, which are used to prevent moisture from entering the enclosure through the inlet hole. Waterproof connectors are installed at the inlet hole to wrap and seal the wires entering the enclosure, preventing moisture from entering the enclosure through the inlet hole.

[0011] Preferably, the lid is provided with an observation window, which allows for observation of the operating status of the equipment inside the box without opening the lid. The observation window is made of transparent waterproof material, which makes it convenient for operators to observe the operating status of the equipment inside the box without having to open the lid frequently, thus reducing the chance of moisture entering.

[0012] Preferably, one end of the lid is provided with a latch, which secures the lid tightly after the box body is connected to the lid. When the box body and the lid are connected, the latch can lock the lid and the box body together.

[0013] The advantages of the embodiments of this application are:

[0014] 1. By using partitions and mounting brackets, the lines are separated and fixed in different line channels, making the line layout neat and enabling quick and accurate identification and location of lines, which greatly improves the efficiency of line maintenance and troubleshooting.

[0015] 2. The heat dissipation holes are angled downwards, and the moisture-proof plate is installed on the surface of the heat dissipation holes. This can promptly dissipate the heat generated by the electronic components inside the cabinet, effectively reduce the temperature inside the cabinet, slow down the aging of components, and extend the service life of the equipment.

[0016] 3. The moisture-proof strip can effectively prevent external moisture from entering through the gap between the lid and the body of the enclosure. The moisture-proof board can absorb the small amount of moisture that enters the enclosure. At the same time, the waterproof connector further prevents moisture from entering from the inlet. Multiple protections ensure the safe and stable operation of the equipment inside the enclosure in a humid environment. Attached Figure Description

[0023] This application provides a photovoltaic current collection device to solve the problems in the prior art. By using partitions and mounting brackets, the lines are separated and fixed in different line channels, resulting in a neat line layout. This allows for quick and accurate identification and location of lines, greatly improving the efficiency of line maintenance and troubleshooting. The heat dissipation holes have a downward-sloping structure, and a moisture-proof plate is installed on the surface of the heat dissipation holes, which can promptly dissipate the heat generated by the electronic components inside the enclosure, effectively reducing the internal temperature, slowing down component aging, and extending the equipment's service life. The moisture-proof strip effectively prevents external moisture from entering through the gap between the enclosure cover and the enclosure body. The moisture-proof plate can absorb any small amount of moisture that enters the enclosure, while the waterproof connector further prevents moisture from entering from the inlet position. Multiple layers of protection ensure the safe and stable operation of the equipment inside the enclosure in a humid environment.

[0024] The technical solution in this application is to solve the above problems, and the overall approach is as follows:

[0025] Example 1:

The box body 1 is made of metal material and has good strength and protective performance. The box cover 2 is hinged to the top of the box body 1 by a hinge and can be rotated around the hinge to open or close.

[0027] The enclosure 1 is equipped with a wiring management component, including multiple partitions 3 and a mounting bracket 4. The partitions 3 divide the interior of the enclosure 1 into multiple independent wiring channels, and the mounting bracket 4 is installed on one side of the partitions 3 for fixing electrical components.

[0028] A moisture-proof strip 7 is provided at the intersection of the box body 1 and the box cover 2. A moisture-proof board 8 is provided on the side of the box body 1 near the moisture-proof strip 7. The moisture-proof board 8 and the box body 1 are detachable. When the box cover 2 is closed, the box cover 2 and the box body 1 are fitted together, and the moisture-proof strip 7 is squeezed, so that the moisture-proof strip 7 and the box cover 2 are tightly fitted with the box body 1 to form a sealed structure and prevent moisture from entering from the gaps.

[0029] The housing 1 has ventilation holes 6 at the corresponding positions of the moisture-proof board 8. Dustproof nets are installed at the ventilation holes 6 to prevent dust from entering the housing 1. When the temperature inside the housing 1 rises, hot air is discharged from the ventilation holes 6 to dissipate heat. The dustproof nets can block dust and prevent dust from entering the housing 1 and affecting the operation of the equipment. The ventilation holes 6 have a downward sloping structure. The moisture-proof board 8 is made of materials with good moisture-proof performance, such as moisture-proof cardboard, and is laid inside the housing 1 on one side of the ventilation holes 6 to absorb any small amount of moisture that may enter.

[0030] The bottom of the enclosure 1 is equipped with multiple connectors 9. These connectors 9 are used to prevent moisture from entering the enclosure 1 through the inlet hole. The waterproof connectors 9 are installed at the inlet hole to wrap and seal the lines entering the enclosure 1, preventing moisture from entering the enclosure 1 through the inlet hole.

[0031] An observation window is provided on the cover 2, which makes it easy to observe the operating status of the equipment inside the box 1 without opening the cover 2. The observation window is made of transparent waterproof material, which makes it easy for operators to observe the operating status of the equipment inside the box 1 without having to open the cover 2 frequently, thus reducing the chance of moisture entering.

[0032] One end of the lid 2 is provided with a latch 5. After the lid 2 is connected to the body 1, it is fixed tightly by the latch 5. When the body 1 is connected to the lid 2, the latch 5 can lock the lid 2 to the body 1.

[0033] By adopting the above technical solution:

[0034] The box body 1 is made of high-strength aluminum alloy and has an overall rectangular shape. The box cover 2 is hinged to the top of the box body 1 by hinges made of stainless steel to ensure durability and corrosion resistance.

[0035] Inside the enclosure 2, multiple partition plates 3 are installed parallel to each other along the length direction. The height of the partition plates 3 is less than the internal height of the enclosure 1, so that the internal space of the enclosure 1 is evenly divided into four independent circuit channels.

[0036] On the contact surface between the box body 1 and the box cover 2, a silicone rubber moisture-proof strip 7 with a D-shaped cross section is installed. The moisture-proof strip 7 is attached to the box body 1 with strong double-sided adhesive to ensure that the box cover 2 forms a seal when closed. On the inner wall of the box body 1 near the moisture-proof strip 7, a moisture-proof board 8 is installed. The moisture-proof board 8 is made of fiber cement board with good moisture-proof performance.

[0037] Three waterproof connectors 9 are evenly distributed at the bottom of the housing 1. After the photovoltaic module cable passes through the connector 9 into the housing 1, the locking nut of the connector 9 is tightened to achieve a waterproof seal.

[0038] Multiple ventilation holes 6 are made at the corresponding positions on the moisture-proof plate 8 on the side of the cabinet 1, and the ventilation holes 6 are arranged at a 45° angle downwards. A metal dust filter is installed at each ventilation hole 6, and the dust filter is fixed to the cabinet 1 with small screws.

[0039] After being put into use, the equipment operated well in normal outdoor environments. The independent wiring channels ensured a clear wiring layout, effectively avoiding electromagnetic interference between lines and improving data acquisition accuracy by 15%. The combination of moisture-proof strips 7 and moisture-proof boards 8, along with the waterproof connectors 9, kept the internal humidity of the equipment within a suitable range for the operation of electrical components. After a rainy season, no moisture was observed inside the equipment. The downward-sloping heat dissipation holes 6, combined with the dustproof mesh, ensured good heat dissipation while effectively preventing dust from entering. The equipment's operating temperature remained stable within the normal operating temperature range, and no malfunctions were caused by dust accumulation.

[0051] The moisture-proof strip 7 has been replaced with a water-swellable rubber strip with self-expanding function. When it comes into contact with moisture, the moisture-proof strip 7 will automatically expand, further enhancing the sealing effect. The moisture-proof board 8 adopts a double-layer structure, with an inner layer of moisture-proof paper and an outer layer of metal aluminum plate, which are bonded together with adhesive, greatly improving the moisture-proof performance.

[0052] Three waterproof connectors 9 are evenly distributed at the bottom of the housing 1. After the photovoltaic module cable passes through the connector 9 into the housing 1, the locking nut of the connector 9 is tightened to achieve a waterproof seal.
