Description

Technical Field

[0001] This utility model relates to the field of photovoltaic equipment technology, specifically to a photovoltaic bracket control terminal mounting housing. Background Technology

[0002] The photovoltaic (PV) mounting bracket control terminal is the core control unit of a PV tracking bracket system. Its main functions are to receive commands, collect environmental and equipment data, and drive the PV bracket to adjust its angles (such as horizontal azimuth and vertical tilt), ultimately achieving precise tracking of the solar trajectory by the PV modules and improving PV power generation efficiency. It serves as a crucial bridge connecting the "command center (such as a monitoring platform)" and the "actuator (such as a drive motor)," and is widely used in single-axis, dual-axis, and other trackable PV mounting bracket systems.

[0003] Existing photovoltaic (PV) bracket control terminals include AC and DC versions. However, the AC and DC versions differ fundamentally in electrical characteristics, protection requirements, and interface layout, resulting in incompatible mounting structures for the AC and DC versions. This necessitates independent housing designs, leading to poor compatibility of the PV bracket control terminal's mounting housing. Furthermore, the need to pre-select a compatible housing during control terminal assembly adds steps and impacts work efficiency. Therefore, there is an urgent need to design a mounting housing for PV bracket control terminals that is compatible with both AC and DC power inputs. Utility Model Content

[0004] The purpose of this utility model is to provide a photovoltaic bracket control terminal mounting housing, which solves the problem that the mounting housing of the photovoltaic bracket control terminal has poor compatibility in the prior art, and that it is necessary to select a compatible mounting housing in advance when assembling the control terminal, which increases the corresponding process and affects work efficiency.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: A photovoltaic bracket control terminal mounting housing includes an outer shell, an inner mounting cavity, a cover plate on the top side of the outer shell for closing the mounting cavity, fixing nuts at the four corners of the bottom side of the inner shell, and vertically arranged support columns threadedly connected to the fixing nuts. The bottom end of the support column is connected to the same power carrier plate, and the power carrier plate has power fixing holes set according to the mounting holes of the power supply body. The middle part of the support column is connected to the same battery carrier plate, and the top end of the support column has a threaded hole. The front and rear sides of the outer shell have interfaces communicating with its interior.

[0006] A further technical solution is that the battery carrier plate has connection holes at its four corners, and the battery carrier plate is slidably connected to the support column through the connection holes; the outer side wall of the support column has external threads along its central axis, and a support nut is threadedly connected to the outer side of the support column below the battery carrier plate, and the top of the support nut abuts against the bottom side of the battery carrier plate.

[0007] A further technical solution is that an upper locking nut is threadedly connected to the outside of the support column below the battery carrier plate, and the bottom end of the upper locking nut abuts against the top side of the battery carrier plate.

[0008] A further technical solution is that the power supply carrier board has through holes at its four corners that are adapted to slide with the support columns, and a lower locking nut is threadedly connected to the outer side of the support column above the power supply carrier board. The bottom end of the lower locking nut abuts against the top side of the power supply carrier board.

[0009] A further technical solution is that a connection point is provided along the inner wall of the interface, and the end of the connection point facing the center of the interface is connected to the same shielding block. The end of the shielding block away from the inside of the shell is connected to a rubber pad, and the rubber pad is tightly fitted to the outside of the shell.

[0010] Compared with the prior art, the beneficial effects of this utility model are: In this invention, by setting up a power supply carrier board and a battery carrier board, the corresponding devices of the AC version and DC version control terminal are respectively adapted and installed on the battery carrier board and the power supply carrier board. This allows the AC version and DC version to be assembled using the same set of mounting housings, avoiding the situation where the mounting housing of the photovoltaic bracket control terminal has poor compatibility, requiring the selection of a compatible mounting housing in advance when assembling the control terminal, which would increase corresponding processes and affect work efficiency.

Detailed Implementation

[0015] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0016] Example 1 Reference Figures 1 to 3 This utility model discloses a photovoltaic bracket control terminal mounting housing, including an outer shell 1, an inner mounting cavity 2, a cover plate 3 for closing the mounting cavity 2 on the top side of the outer shell 1, fixing nuts 4 at the four corners of the bottom side inside the outer shell 1, the fixing nuts 4 are threadedly connected to vertically arranged support columns 5, the bottom end of the support column 5 is connected to the same power carrier plate 6, the power carrier plate 6 is provided with power fixing holes 7 arranged according to the position of the power main body mounting holes, the middle part of the support column 5 is connected to the same battery carrier plate 8, and the top end of the support column 5 is provided with a threaded hole 9; the front and rear sides of the outer shell 1 are provided with interfaces 10 that communicate with its interior.

[0017] The power supply unit includes, but is not limited to, one of the following: Mornsun DC-DC power supply PV200-29B24R3, Mornsun AC-DC power supply LM200-22B24R2, Mean Well DC-DC power supply RSDH-300, and Mean Well AC-DC power supply UHP-200R. Therefore, the power supply mounting holes 7 on the power supply carrier board 6 are respectively designed according to the following: Mornsun DC-DC power supply PV200-29B24R3, Mornsun AC-DC power supply LM200-22B24R2, Mean Well DC-DC power supply RSDH-300, and Mean Well AC-DC power supply UHP-200R. The mounting holes for power supply units such as the Mean Well DC-DC power supply RSDH-300 and the Mean Well AC-DC power supply UHP-200R are designed so that the power supply carrier board 6 is provided with power fixing holes 7 for the power supply units such as the Mornsun DC-DC power supply PV200-29B24R3, the Mornsun AC-DC power supply LM200-22B24R2, the Mean Well DC-DC power supply RSDH-300, and the Mean Well AC-DC power supply UHP-200R, thereby facilitating quick installation of the power supply units.

[0018] In this embodiment, when assembling the control terminal, the power supply carrier board 6 can be adapted to install AC-DC or DC-DC power supplies, thus being compatible with multiple AC or DC power supplies. When assembling the DC version of the control terminal, the battery carrier board 8 can install batteries, 1500V fuses, and other devices. By setting threaded holes 9 at the top end of the support column 5, the control PCB board can be directly fixed to the top of the support column 5 with bolts. The horizontal positions of the interfaces 10 on the front and rear sides of the housing 1 can be different. The interfaces 10 can be fitted with inserts to install AC or DC version switches and other devices. By setting the power supply carrier board 6 and the battery carrier board 8, the corresponding devices of the AC version and DC version control terminals are adapted to be installed on the battery carrier board 8 and the power supply carrier board 6 respectively. This allows the AC version and DC version to be assembled using the same set of mounting housings, avoiding the situation where the mounting housing of the photovoltaic bracket control terminal has poor compatibility, requiring the selection of a compatible mounting housing in advance when assembling the control terminal, which would increase the corresponding processes and affect work efficiency.

[0019] The power and sensor interface 10 can use an IP67-rated aviation plug, which is arranged on both sides of the housing 1. It supports 220VAC or 250~1500VDC power input from photovoltaic strings. At the same time, the interface 10 can be reserved with two RS485 expansion interfaces 10 in an inlay mode.

[0020] Example 2 Based on Example 1, referring to Figures 1 to 2 The battery carrier plate 8 has connection holes at its four corners, and the battery carrier plate 8 is slidably connected to the support column 5 through the connection holes. The outer side wall of the support column 5 has an external thread along its central axis, and a support nut 11 is threadedly connected to the outer side of the support column 5 below the battery carrier plate 8. The top of the support nut 11 abuts against the bottom side of the battery carrier plate 8.

[0021] In this embodiment, an external thread is provided on the outside of the support column 5, and a support nut 11 is engaged. By rotating the support nut 11 to engage with the external thread on the outside of the support column 5, the vertical position of the support nut 11 on the support column 5 is adjusted, and finally the position of the battery carrier plate 8 in the mounting cavity 2 is adjusted. This ensures that the position of the battery carrier plate 8 can be adjusted according to the actual device installed on the power supply carrier plate 6, and avoids the mismatch between the height of the device installed on the power supply carrier plate 6 and the distance between the power supply carrier plate 6 and the battery carrier plate 8 due to the fixed position of the battery carrier plate 8, which would affect the installation of the corresponding device on the power supply carrier plate 6.

[0022] As a preferred implementation scheme, refer to Figures 1 to 2 An upper locking nut 12 is threadedly connected to the outside of the support column 5 below the battery carrier plate 8. The bottom end of the upper locking nut 12 abuts against the top side of the battery carrier plate 8.

[0023] Specifically, by setting the upper locking nut 12, the upper locking nut 12 and the support nut 11 can clamp and fix the battery carrier plate 8, ensuring the stability of the battery carrier plate 8 installation.

[0024] As a preferred implementation scheme, refer to Figures 1 to 2 The power carrier plate 6 has through holes at its four corners that are adapted to slide with the support column 5. The outer side of the support column 5 is threaded with a lower locking nut 13 above the power carrier plate 6. The bottom end of the lower locking nut 13 abuts against the top side of the power carrier plate 6.

[0025] Specifically, by setting the lower locking nut 13, the power carrier board 6 can be clamped and fixed in conjunction with the fixing nut 4.

[0026] Example 3 Based on Example 1, referring to Figure 3 The interface 10 has a connection point 14 along its inner wall. The end of the connection point 14 facing the center of the interface 10 is connected to the same shielding block 15. The end of the shielding block 15 away from the inside of the outer shell 1 is connected to a rubber pad 16. The rubber pad 16 is tightly fitted to the outside of the outer shell 1.

[0027] Specifically, by setting the connection point 14 to connect the shielding block 15 and assembling the control terminal, the interface 10 can be selected according to the actual situation. When it is necessary to install the corresponding device on a certain interface 10, the connection point 14 is broken by pushing the shielding block 15 outward, so that the corresponding device can be installed at the interface 10. By setting the rubber gasket 16, the interface 10 can be sealed and closed to improve the waterproof performance.

[0028] Although the present invention has been described herein with reference to several illustrative embodiments, it should be understood that many other modifications and implementations can be devised by those skilled in the art, which will fall within the scope and spirit of the principles disclosed herein. More specifically, various variations and modifications can be made to the components and / or layout of the subject matter combination within the scope of the disclosure, drawings, and claims. Besides variations and modifications to the components and / or layout, other uses will be apparent to those skilled in the art.
