Description

Technical Field

[0001] This utility model relates to the field of photovoltaic support technology, and in particular to a waterproof structure for a sun-facing photovoltaic support. Background Technology

[0002] The waterproof structure of a sun-facing photovoltaic bracket refers to a special structure designed specifically for outdoor photovoltaic power generation systems that face the sun, aiming to ensure that the photovoltaic panel bracket can effectively prevent moisture intrusion when exposed to the natural environment for a long time.

[0003] Chinese Patent Publication No. CN221978828U, published on 20241108, discloses a waterproof structure for a photovoltaic support, including a steel pipe column and a photovoltaic frame. The outer surface of the photovoltaic frame is fitted with a waterproof sleeve. A support rod is threaded through the surface of the steel pipe column. A connecting frame is fixedly connected to the outer surface of the waterproof sleeve. An operating groove is opened inside the waterproof sleeve. A pull strap is fixedly connected to the inner side of the operating groove. A fixing rod is threaded through the surface of the connecting frame.

[0004] Existing waterproof structures for photovoltaic (PV) brackets, such as those described above, achieve support for the PV bracket within the steel pipe column through the connection between the steel pipe column and the PV bracket, aided by the action of the abutment. The connection between the PV bracket and the waterproof sleeve, due to the shape of the waterproof sleeve, facilitates the waterproof sleeve's action on the outer surface of the steel pipe column, improving its waterproof performance. However, in practical implementation, the method of using the contraction opening at the bottom of the waterproof sleeve often fails to guarantee a good waterproof effect, and the abutment at a fixed point often cannot stably complete the connection between the misaligned steel pipe column and the bracket. Therefore, there is an urgent need to propose a corresponding sun-facing PV bracket waterproof structure to solve these problems. Utility Model Content

[0005] The purpose of this utility model is to provide a waterproof structure for a sun-facing photovoltaic support in order to solve the above-mentioned problems.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A waterproof structure for a solar photovoltaic support includes a support sleeve, a steel pipe column sleeve, a support, and a steel pipe column. The support sleeve and the steel pipe column sleeve are respectively fixedly connected to a base frame and a protrusion on their opposite sides. The base frame and the protrusion are rotatably connected by a shaft, and a locking component for locking the angle between the base frame and the protrusion is integrated between the base frame and the protrusion. Fixing components for fixing the support and the steel pipe column are respectively provided on the outer side of the support sleeve and the steel pipe column sleeve.

[0008] Preferably, the outer wall of the protrusion is screwed with a locking rod, which includes a vertical section and a threaded section. The outer wall of the threaded section is slidably connected to the inner wall of the base frame through an arc groove, and the outer wall of the vertical end abuts against the outer wall of the base frame.

[0009] Preferably, the vertical section has a rough texture on the side near the base frame.

[0010] Preferably, the inner walls of the bracket sleeve and the steel pipe column sleeve are both fixedly connected with rubber sleeves, and the two sets of rubber sleeves respectively abut against the outer walls of the bracket and the steel pipe column.

[0011] Preferably, the inner walls of the bracket sleeve and the steel pipe column sleeve are both fixedly connected to the rubber sleeve by adhesive.

[0012] Preferably, the fixing assembly includes a first fastening rod and a second fastening rod, which are screwed into the outer walls of the bracket sleeve and the steel pipe column sleeve, respectively. The first fastening rod and the second fastening rod pass through two sets of rubber sleeves and abut against the outer walls of the bracket and the steel pipe column, respectively.

[0013] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0014] 1. In this application, the bracket sleeve and the steel pipe column sleeve maintain a stable included angle. The steel pipe column sleeve and the bracket sleeve are respectively inserted into the ends of the steel pipe column and the bracket. The bracket sleeve and the bracket, as well as the steel pipe column and the steel pipe column sleeve, are fixed by fastening rod one and fastening rod two, respectively. The two sets of rubber sleeves ensure the airtightness between the bracket sleeve and the bracket, as well as between the steel pipe column and the steel pipe column sleeve, thereby preventing water from entering the interior of the bracket and the steel pipe column and achieving overall waterproofing of the photovoltaic bracket.

[0015] 2. In this application, the locking rod is rotated to separate its head from the outer wall of the base frame. The bracket sleeve is then deflected according to the solar panel's sun-facing requirements. The bracket sleeve is rotated with the protrusion via a shaft, while the locking rod slides against the inner wall of the base frame via an arc groove. Once the bracket sleeve has deflected to the appropriate angle, the locking rod is rotated in the opposite direction to engage with the protrusion until the head of the locking rod is pressed tightly against the outer wall of the base frame. This re-fixes the base frame and the protrusion, allowing the bracket sleeve and steel pipe column sleeve to be easily adjusted at their angles according to the solar panel's sun-facing requirements, thereby improving the applicability of the waterproof structure for solar-facing photovoltaic brackets.

[0022] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-4 This utility model provides a technical solution:

[0024] A waterproof structure for a solar photovoltaic support includes a support sleeve 1, a steel pipe column sleeve 2, a support and a steel pipe column. The support sleeve 1 and the steel pipe column sleeve 2 are respectively fixedly connected to a base frame 3 and a protrusion 4 on their opposite sides. The base frame 3 and the protrusion 4 are rotatably connected by a shaft 7. A locking component for locking the included angle between the base frame 3 and the protrusion 4 is integrated between the base frame 3 and the protrusion 4. Fixing components for fixing the support and the steel pipe column are respectively provided on the outer side of the support sleeve 1 and the steel pipe column sleeve 2.

[0025] The bracket sleeve 1 and the steel pipe column sleeve 2 maintain a stable included angle. The steel pipe column sleeve 2 and the bracket sleeve 1 are respectively inserted into the ends of the steel pipe column and the bracket. The bracket sleeve 1 and the bracket, as well as the steel pipe column and the steel pipe column sleeve 2, are fixed by fastening rod 1 8 and fastening rod 2 9 respectively. The two sets of rubber sleeves 10 ensure the airtightness between the bracket sleeve 1 and the bracket, as well as between the steel pipe column and the steel pipe column sleeve 2, so as to prevent water from entering the bracket and the steel pipe column and achieve the overall waterproofing of the photovoltaic bracket.

[0026] Specifically, such as Figure 2 and Figure 4As shown, a locking rod 5 is screwed onto the outer wall of the protrusion 4. The locking rod 5 includes a vertical section and a threaded section. The outer wall of the threaded section is slidably connected to the inner wall of the base frame 3 through an arc groove 6. The outer wall of the vertical end abuts against the outer wall of the base frame 3. Rotating the locking rod 5 separates its head from the outer wall of the base frame 3. According to the solar orientation requirement of the photovoltaic panel, the bracket sleeve 1 is deflected. The bracket sleeve 1 is rotatably engaged with the protrusion 4 through the shaft 7. The locking rod 5 slides against the inner wall of the base frame 3 through the arc groove 6 until the bracket sleeve 1 is deflected to a suitable angle. Then, the locking rod 5 is rotated in the opposite direction to screw it onto the protrusion 4 until the head of the locking rod 5 is tightly against the outer wall of the base frame 3. This achieves the re-fixation of the base frame 3 and the protrusion 4, allowing the bracket sleeve 1 and the steel pipe column sleeve 2 to be easily adjusted at the angle according to the solar orientation requirement of the photovoltaic panel. This improves the applicability of the waterproof structure of the solar photovoltaic bracket. The side of the vertical section near the base frame 3 is provided with rough texture to ensure the stability of the contact between the locking rod 5 and the outer wall of the base frame 3.

[0027] Specifically, such as Figure 2 and Figure 3 As shown, rubber sleeves 10 are fixedly connected to the inner walls of both the support sleeve 1 and the steel pipe column sleeve 2. The two sets of rubber sleeves 10 abut against the outer walls of the support and the steel pipe column, respectively, ensuring airtightness between the support sleeve 1 and the support, and between the steel pipe column and the steel pipe column sleeve 2. The inner walls of the support sleeve 1 and the steel pipe column sleeve 2 are fixedly connected to the rubber sleeves 10 with adhesive, thus ensuring convenient assembly and disassembly of the two sets of rubber sleeves 10. The fixing components include fastening rod 1 8 and fastening rod 2 9. Fastening rod 18 and fastening rod 29 are screwed onto the outer walls of bracket sleeve 1 and steel pipe column sleeve 2, respectively. Fastening rod 18 and fastening rod 29 pass through two sets of rubber sleeves 10, and fastening rod 18 and fastening rod 29 abut against the outer walls of the bracket and steel pipe column, respectively. Steel pipe column sleeve 2 and bracket sleeve 1 are inserted into the ends of steel pipe column and bracket, respectively, and the fastening rod 18 and fastening rod 29 are used to fix bracket sleeve 1 to bracket and steel pipe column to steel pipe column sleeve 2.

[0028] Working principle: The bracket sleeve 1 and the steel pipe column sleeve 2 maintain a stable included angle. The steel pipe column sleeve 2 and the bracket sleeve 1 are respectively inserted into the ends of the steel pipe column and the bracket. The bracket sleeve 1 and the bracket, as well as the steel pipe column and the steel pipe column sleeve 2, are fixed by fastening rod 8 and fastening rod 9 respectively. The two sets of rubber sleeves 10 ensure the airtightness between the bracket sleeve 1 and the bracket, and between the steel pipe column and the steel pipe column sleeve 2, thereby preventing water from entering the bracket and the steel pipe column and achieving overall waterproofing of the photovoltaic bracket. Rotating the locking rod 5 separates its head from the outer wall of the base frame 3, at the root... According to the solar panel's sun-facing requirements, the bracket sleeve 1 is deflected. The bracket sleeve 1 is rotatably engaged with the protrusion 4 via the shaft 7, while the locking rod 5 slides against the inner wall of the base frame 3 via the arc groove 6. After the bracket sleeve 1 is deflected to the appropriate angle, the locking rod 5 is rotated in the opposite direction to screw it into the protrusion 4 until the head of the locking rod 5 is tightly against the outer wall of the base frame 3. This achieves the re-fixation of the base frame 3 and the protrusion 4, allowing the bracket sleeve 1 and the steel pipe column sleeve 2 to be conveniently adjusted at the angle according to the solar panel's sun-facing requirements, thereby improving the applicability of the waterproof structure of the sun-facing solar bracket.

[0029] The above description of the embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
