Technical Field
[0001] This utility model relates to the field of anti-salt spray corrosion technology, and in particular to an anti-salt spray corrosion device. Background Technology
[0002] Photovoltaic power generation is a technology that directly converts light energy into electrical energy using the photovoltaic effect at the semiconductor interface. It mainly consists of three parts: solar panels, a controller, and an inverter. The main components are made of electronic devices. Solar cells are connected in series and then encapsulated for protection to form large-area solar cell modules. Combined with components such as a power controller, this forms a photovoltaic power generation device. Photovoltaic support columns need to be installed beforehand to facilitate the installation of the photovoltaic panels.
[0003] In existing technologies, common photovoltaic pillars are typically made of cast cement, which, when exposed to the natural environment for extended periods, can be corroded by salt spray, thus reducing their service life. Therefore, this application provides a salt spray corrosion resistant device to address the problems mentioned in the background section. Utility Model Content
[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing an anti-salt spray corrosion device. This device helps protect photovoltaic columns from corrosion during use, thereby extending their service life and facilitating installation.
[0005] To achieve the above objectives, this utility model provides the following technical solution: an anti-salt spray corrosion device, comprising a first protective cover, a first base plate, a second protective cover, and a third protective cover, wherein the upper ends of the first, second, and third protective covers are all slidably connected with connecting rods, the third protective cover is slidably connected inside the second protective cover, and the second protective cover is slidably connected inside the first protective cover;
[0006] The first protective cover, the second protective cover, and the third protective cover, as well as the three connecting rods, are all provided in two sets. Fixing blocks are fixedly installed on both sides of the two first protective covers. Two of the four fixing blocks have second locking blocks slidably installed inside. Pull rods are fixedly installed at the upper ends of the two second locking blocks. A second spring is connected between the two second locking blocks and the two fixing blocks. The other two of the four fixing blocks have third locking blocks fixedly installed on one side.
[0007] Furthermore, a photovoltaic column is fixedly installed on the upper end of the No. 1 base plate, and a No. 2 handle is fixedly installed on the side of each of the two No. 1 protective covers that are far apart from each other.
[0008] Furthermore, two No. 1 locking blocks are slidably arranged inside the upper end of the photovoltaic column, and a No. 1 spring is connected between each of the two No. 1 locking blocks and the photovoltaic column.
[0009] Furthermore, a fixing plate is fixedly installed on the upper side of one end of three of the six connecting rods, and a handle is fixedly installed on the upper end of the two third protective covers.
[0010] Furthermore, a second base plate is fixedly installed around the lower end of each of the two first protective covers, and each of the two second base plates has two fixing holes.
[0011] Furthermore, both of the aforementioned third protective covers have through holes at their upper ends.
[0012] Furthermore, the surfaces of the two protective covers No. 1, No. 2 and No. 3 that are far apart from each other are all coated with an anti-salt spray corrosion coating.
[0013] Furthermore, the inner diameter of the two protective covers No. 3 is equal to the outer diameter of the photovoltaic column.
[0014] This utility model has the following beneficial effects:
[0015] 1. The present invention proposes an anti-salt spray corrosion device. When using the device, two No. 1 protective covers are aligned, and the No. 3 snap-fit block is inserted into the two fixing blocks. The No. 3 snap-fit block presses against the No. 2 snap-fit block. When the two No. 1 protective covers are completely in contact, the No. 2 snap-fit block is inserted into the No. 3 snap-fit block, which helps to fix the two No. 1 protective covers together. Then, the fixing plate is pushed to rotate 180 degrees, which helps to fix the two No. 2 and No. 3 protective covers together in pairs through the six connecting rods. This facilitates the rapid installation of the device around the photovoltaic column.
[0016] 2. The anti-salt spray corrosion device proposed in this utility model, after installation, pulls the two No. 1 handles to move the No. 3 protective cover upwards, and the No. 3 protective cover moves the No. 2 protective cover upwards. When the No. 3 protective cover moves to the upper end of the photovoltaic column, it squeezes the No. 1 locking block. When the through hole is aligned with the No. 1 locking block, the No. 1 spring pushes the No. 1 locking block into the through hole, which helps to fix the No. 3 protective cover to the upper end of the photovoltaic column and completely wraps around the photovoltaic column, thereby preventing it from being corroded and reducing its service life.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0027] Reference Figure 1 , Figure 4 , Figure 5 , Figure 6 and Figure 7An embodiment of this utility model provides an anti-salt spray corrosion device, including a first protective cover 2, a first base plate 4, a second protective cover 16, and a third protective cover 17. The upper ends of the first protective cover 2, the second protective cover 16, and the third protective cover 17 are all slidably snapped with connecting rods 18. The third protective cover 17 is slidably snapped with inside the second protective cover 16. The second protective cover 16 is slidably snapped with inside the first protective cover 2. The first protective cover 2, the second protective cover 16, the third protective cover 17, and the three connecting rods 18 are all provided in two sets. Fixing blocks 3 are fixedly installed on both sides of the two first protective covers 2. Two of the four fixing blocks 3 have second snap-fit blocks 13 slidably installed inside. The upper ends of the two second snap-fit blocks 13 are all fixedly installed with pull rods 11. A second spring 12 is connected between the two second snap-fit blocks 13 and the two fixing blocks 3. The other two of the four fixing blocks 3 have third snap-fit blocks 14 fixedly installed on one side.
[0028] Specifically, aligning the two No. 1 protective covers 2 helps to enclose the photovoltaic column 1 inside them. Then, the two No. 1 protective covers 2 are brought together, allowing the two No. 3 snap-fit blocks 14 to enter the interior of the two fixing blocks 3, pressing the No. 2 snap-fit block 13. When the two No. 1 protective covers 2 are fully attached, the No. 2 spring 12 pushes the No. 2 snap-fit block 13 into the interior of the No. 3 snap-fit block 14, which helps to fix the two No. 1 protective covers 2 together. Pushing the three fixing plates 15 moves the three fixing plates 15, which drives the three connecting rods 18 to rotate 180 degrees and also pushes the other three connecting rods 18 to move, which helps to fix the two No. 3 protective covers 17 and the No. 2 protective cover 16 together in pairs. Pulling the pull rod 11 helps to move the No. 2 snap-fit block 13 upward, which makes it easier to separate the two No. 1 protective covers 2 and disassemble them.
[0029] Reference Figure 1 , Figure 2 , Figure 3 , Figure 5 , Figure 6 and Figure 7A photovoltaic column 1 is fixedly installed on the upper end of the No. 1 base plate 4. A No. 2 handle 6 is fixedly installed on the side of the two No. 1 protective covers 2 that are far apart from each other. Two No. 1 locking blocks 10 are slidably installed inside the upper end of the photovoltaic column 1. A No. 1 spring 9 is connected between the two No. 1 locking blocks 10 and the photovoltaic column 1. A fixing plate 15 is fixedly installed on the upper side of one end of three of the six connecting rods 18. A No. 1 handle 5 is fixedly installed on the upper end of the two No. 3 protective covers 17. A No. 2 base plate 7 is fixedly installed around the lower end of the two No. 1 protective covers 2. Two fixing holes 8 are opened on the two No. 2 base plates 7. Through holes 19 are opened through the upper end of the two No. 3 protective covers 17. The surfaces of the two No. 1 protective covers 2, No. 2 protective covers 16 and No. 3 protective covers 17 that are far apart from each other are sprayed with an anti-salt spray corrosion coating. The inner diameter of the two No. 3 protective covers 17 is equal to the outer diameter of the photovoltaic column 1.
[0030] Specifically, pulling the two No. 1 handles 5 moves the two No. 3 protective covers 17 upwards, which in turn moves the two No. 2 protective covers 16 upwards, helping to enclose the photovoltaic column 1, preventing it from being corroded, and thus improving its service life. When the two No. 3 protective covers 17 move to the upper end of the photovoltaic column 1, they will squeeze the No. 1 locking block 10. When the through hole 19 and the No. 1 locking block 10 are aligned, the No. 1 spring 9 pushes the No. 1 locking block 10 into the through hole 19, which helps to fix the two No. 3 protective covers 17 to the upper end of the photovoltaic column 1 and prevent them from falling. Passing the bolt through the fixing hole 8 and fixing it to the upper end of the No. 1 base plate 4 helps to fix the two No. 2 base plates 7 and the two No. 1 protective covers 2 to the upper end of the No. 1 base plate 4. The two No. 2 handles 6 help to move the two No. 1 protective covers 2.
[0031] Working principle: When using this device, align the two No. 1 protective covers 2, insert the No. 3 snap-fit block 14 into the two fixed blocks 3, and the No. 3 snap-fit block 14 presses against the No. 2 snap-fit block 13. When the two No. 1 protective covers 2 are completely fitted together, the No. 2 snap-fit block 13 inserts into the No. 3 snap-fit block 14, which can fix the two No. 1 protective covers 2 together, thereby wrapping the photovoltaic column 1. Then, fix the No. 2 base plate 7 to the upper end of the No. 1 base plate 4 with bolts. Then, push the three fixed plates 15 to move the three connecting rods 18. Rotate it 180 degrees, then pull the first handle 5 to move the two third protective covers 17 upwards. The two third protective covers 17 move the two second protective covers 16 upwards. When the third protective cover 17 moves to the upper end of the photovoltaic column 1, it squeezes the first locking block 10. When the through hole 19 is aligned with the first locking block 10, the first spring 9 pushes the first locking block 10 into the through hole 19, which helps to fix the third protective cover 17 to the upper end of the photovoltaic column 1 and helps to completely wrap around the photovoltaic column 1.
[0032] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
