Abstract
Description
Technical Field
[0001] This utility model belongs to the field of photovoltaic engineering technology, and in particular relates to a waterproof structure for the roof of a photovoltaic project. Background Technology
[0002] The waterproofing structure of a rooftop photovoltaic (PV) system is one of the key factors ensuring its long-term stable operation. During the design and construction process, the roof's waterproofing performance must be considered to prevent rainwater leakage from damaging the building structure or affecting the PV system's power generation efficiency.
[0003] Existing waterproof structures for photovoltaic roofs typically use corrugated steel sheets as drainage structures to divert rainwater. However, this drainage structure has many gaps, allowing water to seep into the roof during flow. This results in poor waterproofing and a large amount of water still entering the roof. Over time, this accumulation can damage the roof structure and create safety hazards. Therefore, we propose a new waterproof structure for photovoltaic roofs. Utility Model Content
[0004] The purpose of this utility model is to provide a waterproof structure for photovoltaic (PV) rooftops. Specifically, a waterproof cover is fitted over the bottom of the PV support column. The bottom of the waterproof cover is then tightly fitted to the top of the roof structure via a rubber sealing ring. The rubber sealing cover seals the outside of the PV support column, preventing water from entering through gaps. The rubber sealing ring seals the gap between the roof structure and the waterproof cover, further preventing water from entering. This provides a better seal and prevents water from entering the bolt installation seams and affecting the roof structure. This solves the problem of existing waterproof structures using corrugated steel sheets as a drainage structure, which results in numerous gaps, poor waterproofing, and the continued entry of water stains. Over time, this accumulation can damage the roof structure and pose safety hazards.
[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

The bottom of the spring is fixedly connected to the top of the mounting plate. The bottom of the fixing block is fixedly connected to the top of the mounting plate. The side of the locking block near the inner convex ring contacts a limiting plate. The bottom of the limiting plate is fixedly connected to the bottom of the mounting plate. The top and bottom of the side of the locking block near the inner convex ring are both sloped.
[0009] Furthermore, a pressing assembly is provided above the waterproof cover. The pressing assembly includes a pressure ring. Limiting blocks are fixedly connected to all four sides of the outer side of the photovoltaic support column. A vertical rod is slidably connected inside the limiting block.

[0024] 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.
[0025] Please see Figure 1-5 As shown, this utility model is a waterproof structure for a photovoltaic roof, including a roof structure 1. A photovoltaic support column 11 is installed on top of the roof structure 1. An mounting plate 111 is fixedly connected to the bottom of the photovoltaic support column 11. The mounting plate 111 is fixedly connected to the roof structure 1 by bolts. A waterproof component 12 is installed on the outer side of the bottom of the roof structure 1. The waterproof component 12 includes a waterproof cover 121. A rubber sealing sleeve 122 is fixedly connected to the top of the waterproof cover 121. A rubber sealing ring 123 is fitted on the bottom of the waterproof cover 121. An inner convex ring 124 is fixedly connected to the bottom of the inner ring of the waterproof cover 121. The inner side of the waterproof cover 121 slides against the outer surface of the photovoltaic support column 11. The connection is made so that the inner side of the rubber sealing sleeve 122 contacts the outer surface of the photovoltaic support column 11. By setting the waterproof component 12, specifically by putting the waterproof cover 121 on the bottom of the photovoltaic support column 11, the bottom of the waterproof cover 121 will be tightly attached to the top of the roof structure 1 through the rubber sealing ring 123. The rubber sealing sleeve 122 plays a sealing role on the outside of the photovoltaic support column 11 to prevent water from entering the interior from the gap. The rubber sealing ring 123 seals the gap between the roof structure 1 and the waterproof cover 121, further preventing water from entering the interior, thereby playing a better sealing role and preventing water from entering the bolt installation seam and affecting the roof structure 1.
[0026] The bottom of the inner convex ring 124 contacts the top of the mounting plate 111. The top of the waterproof cover 121 is conical, with the top conical surface of the waterproof cover 121 being higher at the top and lower at the bottom. The outer side of the rubber sealing sleeve 122 is also conical, with the top conical surface of the rubber sealing sleeve 122 being higher at the top and lower at the bottom. Since both the inner convex ring 124 and the top of the waterproof cover 121 are conical, they can better guide rainwater and reduce water residue.
[0027] The inner convex ring 124 is provided with four locking blocks 14 on its outer four sides. The four locking blocks 14 are connected to the same parts. The front and back of the locking blocks 14 are rotatably connected to the fixing blocks 142 by pins. The side of the locking block 14 away from the inner convex ring 124 is fixedly connected to the spring piece 141. The bottom of the spring piece 141 is fixedly connected to the top of the mounting plate 111. The bottom of the fixing block 142 is fixedly connected to the top of the mounting plate 111. The side of the locking block 14 near the inner convex ring 124 contacts the limiting plate 143. The bottom of the limiting plate 143 is fixedly connected to the bottom of the mounting plate 111. The top and bottom of the side of the locking block 14 near the inner convex ring 124 are both set with slopes. The limiting plate 143 is used to limit the locking block 14, so that the locking block 14 is in a vertical state, which makes it easy for the inner convex ring 124 to push the locking block 14 smoothly.
[0028] A pressing assembly 13 is provided above the waterproof cover 121. The pressing assembly 13 includes a pressure ring 131. Limiting blocks 132 are fixedly connected to all four sides of the outer side of the photovoltaic support column 11. A vertical rod 133 is slidably connected inside the limiting block 132. The bottom of the vertical rod 133 is fixedly connected to the top of the pressure ring 131. The top of the vertical rod 133 passes through the limiting block 132 and extends to the outside. A limiting ring 134 is fixedly connected to the outer surface of the vertical rod 133. A counterweight 135 is inserted into the outer side of the vertical rod 133. By setting the pressing component 13, specifically pulling the pressure ring 131 downward, the vertical rod 133 slides on the limiting block 132. After the pressure ring 131 contacts the top of the waterproof cover 121, the counterweight block 135 is inserted into the vertical rod 133 and contacts the limiting ring 134 to increase the gravity, so that the pressure ring 131 presses the waterproof cover 121 downward, which can make the rubber sealing ring 123 at the bottom of the waterproof cover 121 fit tightly with the roof structure 1 again, improving the sealing effect.
[0029] The bottom of the counterweight 135 contacts the top of the limiting ring 134, which is located above the limiting block 132. A protrusion 136 is fixedly connected to the bottom of the outer surface of the vertical rod 133. The bottom of the pressure ring 131 contacts the top of the waterproof cover 121. When the pressure ring 131 is not in use, the protrusion 136 is inside the limiting block 132 to increase friction and fix the pressure ring 131 at the bottom of the limiting block 132, thus facilitating operation by the staff.
[0030] The bottom of the waterproof cover 121 contacts the top of the roof structure 1, the bottom of the rubber sealing ring 123 contacts the top of the roof structure 1, the outer side of the inner convex ring 124 protrudes from the inner wall of the waterproof cover 121, and the top of the inner convex ring 124 is chamfered.
[0031] One specific application of this embodiment is:
[0032] After the mounting plate 111 at the bottom of the photovoltaic support column 11 is fixed to the roof structure 1 with bolts, the waterproof cover 121 is pushed downwards. The inner side of the rubber sealing sleeve 122 slides on the photovoltaic support column 11. Due to the large friction of the rubber sealing sleeve 122, the rubber sealing sleeve 122, along with the waterproof cover 121, will be above the mounting plate 111 during the installation of the photovoltaic support column 11, thus not affecting the installation of the photovoltaic support column 11 by the workers. When the bottom of the waterproof cover 121 contacts the top of the roof structure 1, the bottom of the rubber sealing ring 123 will contact the roof structure. When the top of component 1 contacts the inner convex ring 124 and the locking block 14, the locking block 14 will be pushed. The bottom of the locking block 14 will rotate on the fixing block 142, and the locking block 14 will squeeze the spring piece 141, allowing the inner convex ring 124 to pass smoothly through the locking block 14. When the inner convex ring 124 moves to the bottom of the locking block 14, the locking block 14 will reset under the elastic action of the spring piece 141, locking and fixing the inner convex ring 124. The limiting plate 143 is used to limit the locking block 14, keeping the locking block 14 in a vertical state, so that the inner convex ring 124 can push the locking block 14 smoothly. At this time, the waterproof cover The bottom of the photovoltaic support column 121 is tightly attached to the top of the roof structure 1 via a rubber sealing ring 123. The rubber sealing sleeve 122 seals the outside of the photovoltaic support column 11, preventing water from entering the interior through gaps. The rubber sealing ring 123 seals the gap between the roof structure 1 and the waterproof cover 121, further preventing water from entering the interior, thus achieving a better sealing effect and preventing water from entering the bolt installation seam and affecting the roof structure 1. After the waterproof cover 121 is installed, pulling down the pressure ring 131 will cause the vertical rod 133 to slide on the limiting block 132. After the protrusion 136 leaves the limiting block 132, and the pressure ring 131 contacts the top of the waterproof cover 121, the counterweight 135 is inserted into the vertical rod 133 and contacts the limiting ring 134 to increase the gravity, so that the pressure ring 131 presses the waterproof cover 121 downward, which can make the rubber sealing ring 123 at the bottom of the waterproof cover 121 fit tightly with the roof structure 1 again, improving the sealing effect. When the pressure ring 131 is not in use, the protrusion 136 is in the limiting block 132 to increase the friction force, so that the pressure ring 131 is fixed at the bottom position of the limiting block 132, thereby facilitating the operation of the staff.
