A pile hole protection device for photovoltaic micro-grown piles

Abstract

This invention relates to a pile hole protection device for photovoltaic micro-grown piles, comprising a sealing shell for sealing the pile hole opening. The sealing shell has an upward-facing receiving cavity for accommodating heavy objects. The sealing shell includes a mating annular wall for tightly fitting against the pile hole opening, forming a closed space within the pile hole. The diameter of the mating annular wall gradually decreases from top to bottom. An annular support plate is connected to the upper edge of the sealing shell, supporting the edge of the pile hole opening. After the pile hole protection device is placed at the pile hole opening, the load within the receiving cavity ensures a tight fit between the mating annular wall of the sealing shell and the pile hole opening, preventing rain, dust, and organisms from entering and thus avoiding blockage of the pile hole. This prepares the site for the next step of the process, improving construction efficiency. Furthermore, the load placed within the receiving cavity makes the pile hole protection device less susceptible to being scraped off. This not only effectively protects the pile hole but also allows for repeated use, reducing costs.

Description

Technical Field

[0001] This invention belongs to the field of photovoltaic micro-grouting piles, and specifically relates to a pile hole protection device for photovoltaic micro-grouting piles. Background Technology

[0002] As the load-bearing component of the photovoltaic power generation unit, the photovoltaic support foundation plays a crucial role in the construction of the entire power station. For mountain photovoltaic projects, due to the significant elevation differences, cast-in-place piles are often used for the photovoltaic support foundation.

[0003] For example, Chinese patent document CN201125935U discloses a micro-hole grouting pile suitable for solar photovoltaic support foundation, which includes a pile hole, a hollow metal tube, concrete and a support connecting plate. The hollow metal tube is placed in the pile hole and protrudes from the ground. The concrete fills the annular space formed by the hollow metal tube and the pile hole to fix the hollow metal tube. The support connecting plate is fixed on the top of the hollow metal tube to connect the photovoltaic support.

[0004] To improve work efficiency during the construction of the aforementioned micro-hole cast-in-place piles, a large number of micro-holes are typically constructed on the ground in the photovoltaic field area first. Then, a hollow metal tube is inserted into each micro-hole, and concrete is poured in. After the concrete solidifies, a micro-hole cast-in-place pile is formed. However, constructing the micro-holes involves a significant amount of work and requires a long construction time. To prevent stones, small animals, and rainwater from falling into the holes, protective measures are necessary.

[0005] Currently, the protective measures for micropiles are relatively simple, typically involving covering the hole opening with plastic sheeting and then weighing down the area with stones. However, this plastic sheeting is frequently blown away by the wind or carelessly discarded, resulting in poor protection and environmental pollution. Furthermore, due to the small size of the micropiles, they can be missed during concrete pouring in areas with weeds, making it difficult for equipment to enter the photovoltaic field later and increasing the cost of filling gaps. Summary of the Invention

[0006] The purpose of this invention is to provide a protection device for the pile hole of photovoltaic micro-grown piles, so as to solve the technical problem that the protection effect of micro-pile holes using plastic cloth for protection in the prior art is poor.

[0007] To achieve the above objectives, the technical solution of the pile hole protection device for photovoltaic micro-grown piles of the present invention is as follows:

[0008] A protective device for the pile hole of a photovoltaic micro-grown pile includes a sealing shell for sealing the opening of the pile hole. The sealing shell has an upward-facing receiving cavity for accommodating heavy objects. The sealing shell includes a mating annular wall for tightly fitting with the opening of the pile hole to form a closed space in the pile hole. The diameter of the mating annular wall gradually decreases from top to bottom. An annular support plate is connected to the upper edge of the sealing shell for supporting the edge of the pile hole opening.

[0009] The beneficial effects are as follows: After the pile hole protection device of the present invention is placed at the opening of the pile hole, the supporting material inside the receiving cavity ensures that the mating ring wall of the sealing shell fits tightly against the opening of the pile hole, preventing rain, dust, and organisms from falling in, thereby preventing blockage of the pile hole and preparing for the next step of the process, thus improving construction efficiency. Furthermore, the presence of the supporting material inside the receiving cavity makes the pile hole protection device less susceptible to being scraped off. This not only effectively protects the pile hole but also allows for repeated use, reducing costs. In addition, the annular support plate can support the pile hole protection device on the edge of the pile hole opening after it is stepped on, preventing the device from falling into the pile hole.

[0010] As a further improvement, the sealing shell and the annular support plate are integrally machined.

[0011] The beneficial effect is that this design reduces the steps involved in connecting the sealing shell and the annular support plate, which helps improve on-site construction efficiency.

[0012] As a further improvement, the sealing shell is a flexible shell, the annular support plate is a flexible plate, and a rigid support rod is connected to the annular support plate.

[0013] The beneficial effects are: the flexible shell can deform when there is some collapse at the pile hole opening to adapt to the irregular opening and ensure a tight fit between the sealing shell and the opening. Meanwhile, the support rod provides support, preventing the pile hole protection device from falling into the pile hole.

[0014] As a further improvement, the number of support rods is two, and the two support rods are arranged in a cross shape.

[0015] The beneficial effect is that this design ensures effective support while reducing the number of support rods, which facilitates the installation of the support rods.

[0016] As a further improvement, the upper side of the annular support plate is provided with a pair of connecting protrusions, and the connecting protrusions are provided with connecting blind holes for the end of the support rod to be inserted. The openings of the two connecting blind holes of the pair of connecting protrusions are arranged opposite to each other.

[0017] The beneficial effect is that this design facilitates the assembly and disassembly of the support rod.

[0018] As a further improvement, the thickness of the annular support plate is greater than the thickness of the sealing shell.

[0019] The beneficial effect is that this design allows the annular support plate to provide a certain degree of support. With the joint support of the annular support plate and the support rod, it further ensures that the pile hole protection device will not fall into the pile hole.

[0020] As a further improvement, the thickness of the annular support plate gradually decreases from the inside to the outside along the radial direction of the sealing shell.

[0021] As a further improvement, the sealing shell has a hemispherical structure.

[0022] The beneficial effect is that this design makes the pile hole protection device resemble an inverted straw hat structure, increasing its aesthetic appeal.

[0023] As a further improvement, the sealing shell and / or annular support plate have warning colors.

[0024] The beneficial effects are: the warning colors can alert people or small animals, and make it easier to find the pile holes during subsequent construction, preventing omissions.

[0025] As a further improvement, the sealing shell is a flexible shell, and the annular support plate is a rigid plate.

[0026] The beneficial effect is that the pile hole protection device can be supported by a rigid plate without the need for additional rigid support components. Attached Figure Description

[0035] The features and performance of the present invention will be further described in detail below with reference to embodiments.

[0036] Example 1 of the pile hole protection device for photovoltaic micro-grown piles of the present invention:

[0037] like Figure 1 and Figure 4 As shown, the pile hole protection device 101 is shaped like an inverted straw hat and includes a sealing shell 11 and an annular support plate 12. The sealing shell 11 has a hemispherical structure, and the upper edge of the sealing shell 11 is connected to the annular support plate 12. The annular support plate 12 is used to support the edge of the opening of the pile hole 103.

[0038] In this embodiment, the sealing shell 11 has an upward-facing receiving cavity 13, which is used to hold heavy objects, such as soil or stones, making the sealing shell 11 less susceptible to being blown away by wind. The sealing shell 11 includes a mating ring wall for tightly fitting with the opening of the pile hole 103, so that the pile hole 103 forms a closed space. Since the diameter of the mating ring wall gradually decreases from top to bottom, under the action of the heavy object in the receiving cavity 13, the mating ring wall can fit tightly with well openings of different sizes. This not only improves the versatility of the pile hole protection device 101, but also prevents rainwater from entering the pile hole 103 when used in mountainous areas with a certain slope, thereby protecting the quality of the pile hole 103 and reducing rework. The mating ring wall is the large-diameter section of the sealing shell 11.

[0039] like Figure 2 and Figure 3 As shown, the sealing shell 11 and the annular support plate 12 are integrally formed. Specifically, the sealing shell 11 is a flexible shell, and the annular support plate 12 is a flexible plate, meaning that the sealing shell 11 and the annular support plate 12 are integrally injection molded. This design allows the sealing shell 11 to deform to adapt to irregular openings when the opening of the pile hole 103 experiences some collapse, ensuring a tight fit between the sealing shell 11 and the opening. The injection molding material for both the sealing shell 11 and the annular support plate 12 is rubber. In other embodiments, the injection molding material for the sealing shell and the annular support plate can be PVC.

[0040] In this embodiment, since both the sealing shell 11 and the annular support plate 12 are supported by flexible materials, a rigid support rod 15 is connected to the annular support plate 12 to ensure that the pile hole protection device 101 does not fall into the pile hole 103. The support rod 15 not only supports the sealing shell 11 and the annular support plate 12, but also has the ability to withstand being stepped on by animals or people. The support rod 15 is a steel rod and passes above the receiving cavity 13.

[0041] In this embodiment, there are two support rods 15. The specific installation method of the support rods 15 is as follows: two pairs of connecting protrusions 14 are provided on the upper side of the annular support plate 12. The connecting protrusions 14 are provided with connecting blind holes 16 for the ends of the support rods 15 to be inserted. The openings of the two connecting blind holes 16 of each pair of connecting protrusions 14 are arranged opposite each other, and the four connecting protrusions 14 are evenly spaced around the circumference of the annular support plate 12 so that the two support rods 15 are arranged in a cross shape after being inserted into the corresponding connecting blind holes 16. In other embodiments, the number of support rods is set as needed, such as one or more.

[0042] In this embodiment, the thickness of the annular support plate 12 is greater than the thickness of the sealing shell 11, so that the annular support plate 12 has a certain supporting function. With the joint support of the annular support plate 12 and the support rod 15, it is further ensured that the pile hole protection device 101 will not fall into the pile hole 103. The thickness of the annular support plate 12 gradually decreases from the inside to the outside along the radial direction of the sealing shell 11.

[0043] In this embodiment, both the annular support plate 12 and the sealing shell 11 have warning colors to alert people or small animals, and to facilitate subsequent construction and prevent omissions.

[0044] During construction, such as Figure 1 and Figure 4 As shown, pile holes 103 are first constructed on the stratum 102. After the construction is completed, the pile hole protection device 101 is sealed at the opening of the pile hole 103, and soil is put into the receiving cavity 13 of the sealing shell 11 to complete the protection of the pile hole 103.

[0045] The pile hole protection device of the present invention can prevent rain, dust, organisms, etc. from falling in, thus avoiding blockage of the pile hole and preparing for the next step of the process, thereby improving construction efficiency. After the load is placed in the cavity, it is not easily scraped away, which not only effectively protects the pile hole, but also allows for repeated use, reducing costs.
