Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaic solar module installation, in particular to a photovoltaic solar module installation microporous cast-in-place pile structure. Background Art

[0002] See also Figure 1 The micro-porous cast-in-place pile structure used in existing photovoltaic solar panels is installed. During installation, a cast-in-place hole approximately 180 mm in diameter and 1500-2000 mm deep is first drilled in the ground. The steel cage 10 and steel pipe 20 assembly is placed into the cast-in-place hole and concrete is poured. During pouring, the bottom of the steel pipe 20 is open, so during vibration, the concrete enters the pipe 20 from the bottom. This shortens the insertion depth of the support 30 and reduces its stability. Extending the upper end of the steel pipe 20 would increase costs. Utility Model Content

[0003] The purpose of the utility model is to provide a microporous cast-in-place pile structure for installing photovoltaic solar panels. By installing a closed structure at the lower end or inside the lower end of a steel pipe, concrete will not enter the steel pipe during vibration, thereby ensuring that the pillar has sufficient installation depth and improving the stability of the pillar installation.

[0004] To achieve the above-mentioned purpose, the utility model provides a micro-porous cast-in-place pile structure for installing photovoltaic solar panels, including a steel cage, a steel pipe, a pillar and fixing bolts. The lower end of the steel pipe is welded to the steel cage, and the pillar is inserted from the upper end of the steel pipe. The steel pipe and the pillar are connected by fixing bolts; a closed structure is installed at the lower end of the steel pipe or inside the lower end; in the installed state, the steel cage and the lower end of the steel pipe are buried in concrete.

[0005] The closed structure is a plate body fixedly connected to the steel pipe.

[0006] The closed structure includes a ring body and a leakage plate. The ring body is fixed to the inside of the steel pipe. The leakage plate is clamped inside the steel pipe. The leakage plate is located on the lower side of the ring body. A water seepage structure is provided on the leakage plate. When the leakage plate and the ring body are in contact, the water seepage structure is closed by the ring body.

[0007] The water seepage structure is a hole arranged on the seepage plate.

[0008] The water seepage structure is a notch arranged on the edge of the seepage plate.

[0009] A waterproof cover is installed on the pillar at the top of the steel pipe, and the waterproof cover is connected and sealed with the pillar by means of sealant.

[0024] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0025] Example 1:

[0026] See Figure 2 A microporous cast-in-place pile structure for installing photovoltaic solar panels includes a steel cage 10, a steel pipe 20, pillars 30, and fixing bolts 40. The lower end of the steel pipe 20 is welded to the steel cage 10, and the pillars 30 are inserted from the upper end of the steel pipe 20. The steel pipe 20 and the pillars 30 are connected by fixing bolts 40. A sealing structure 21 is installed at the lower end of the steel pipe 20 or inside the lower end. When installed, the steel cage 10 and the lower end of the steel pipe 20 are buried in concrete. By installing the sealing structure 21 at the lower end of the steel pipe 20 or inside the lower end of the steel pipe 20, concrete is prevented from entering the steel pipe 20 during vibration, thereby ensuring sufficient installation depth for the pillars 30 and improving the stability of the installation of the pillars 30.

[0027] In one embodiment, the closed structure 21 is a plate fixedly connected to the steel pipe 20. The plate can be a metal plate, and the metal plate is welded to the steel pipe 20.

[0028] In another embodiment, see Figure 3 、 4 The closed structure 21 includes a ring body 211 and a leakage plate 212. The ring body 211 is fixed to the inside of the steel pipe 20, and the leakage plate 212 is clamped inside the steel pipe 20. The leakage plate 212 is located on the lower side of the ring body 211. A water seepage structure is provided on the leakage plate 212, and when the leakage plate 212 is in contact with the ring body 211, the water seepage structure is closed by the ring body 211. In this solution, the ring body 211 is a metal ring, and the ring body 211 is fixed to the steel pipe 20 by welding, or the ring body 211 is fixed by squeezing the ring body 211 on the outer wall of the steel pipe 20. The leakage plate 212 is clamped on the lower side of the ring body 211. During transportation and handling, the leakage plate 212 is not easy to fall off. When pouring concrete, the lower end of the steel pipe 20 is sealed by the leakage plate 212, and the concrete will not enter the steel pipe 20 during vibration. After the pouring is completed, when the concrete has not solidified, a rod with a conical bottom is inserted from the upper end of the steel pipe 20. The rod moves up and down to impact the leakage plate 212, so that the leakage plate 212 is separated from the ring body 211. Figure 4 As shown, this facilitates drainage of the interior of the steel pipe 20 during later use.

[0029] In one embodiment, the water seepage structure is a hole provided on the seepage plate 212 .

[0030] In another embodiment, see Figure 5 The water seepage structure is a notch 213 set on the edge of the seepage plate 212.

[0031] Example 2:

[0032] Based on Example 1, see Figure 6 、 7 A waterproof cover 31 is installed on the support 30 at the top of the steel pipe 20. The waterproof cover 31 and the support 30 are sealed with sealant 32. This prevents rainwater and condensation from entering the steel pipe 20 through the gap between the support 30 and the steel pipe 20, and also covers the fixing bolts 40 below. Silicone sealant 32 can be used. Apply sealant 32 to both the waterproof cover 31 and the support 30.

[0033] The working principle or action process of the utility model is as follows:

[0034] See also Figure 2 During installation, the combination of the steel cage 10 and the steel pipe 20 is placed in the pouring hole to pour concrete. During pouring, the closed structure 21 at the lower end of the steel pipe 20 prevents the concrete from entering the steel pipe 20 during vibration, thereby ensuring that the support 30 has sufficient installation depth and improving the stability of the installation of the support 30.

[0035] Because photovoltaic modules are installed outdoors in mountainous terrain, water can accumulate inside the steel pipe 20 after the enclosed structure 21 is installed. This water, which originates from rain or condensation on the surface of the support 30, flows into the steel pipe 20 through the gaps between the support 30 and the steel pipe 20. Because this water does not evaporate easily, it accelerates corrosion at the junction of the support 30 and the steel pipe 20, shortening the service life of the metal structure. Therefore, drainage or waterproofing within the steel pipe 20 also needs to be addressed after the enclosed structure 21 is installed.

[0036] Therefore, this application proposes two solutions: one is to use a detachable seepage plate 212 structure; the other is to install a waterproof cover 31 on the top of the steel pipe 20 on the support 30. In the first solution, water entering the steel pipe 20 will be absorbed by the concrete; in the second solution, rainwater and condensation are unlikely to enter the steel pipe 20.
