Description

Technical Field

[0001] This utility model relates to the field of photovoltaic construction technology, specifically to a protective device for photovoltaic precast pile foundation construction. Background Technology

[0002] Protective devices used in the construction of photovoltaic precast pile foundations are a general term for various specialized equipment used to position and calibrate the pile body, protect the pile hole / pile opening, and prevent safety hazards during the construction process of photovoltaic precast pile driving and hole formation.

[0003] During the construction of photovoltaic precast pile foundations, the positioning accuracy of the piles directly affects the subsequent installation of photovoltaic brackets and the overall system stability. Traditional construction methods often rely on manual calibration or simple positioning tools, lacking dedicated limiting structures. During pile driving, external disturbances and uneven settlement of the foundation can easily cause the piles to deviate from the preset axis, resulting in tilting deviations. This not only requires secondary rework and adjustment, increasing construction costs and time, but may also reduce the foundation's bearing capacity due to substandard pile verticality, posing safety hazards. Furthermore, during the construction gap between the completion of the pile hole and the insertion of the precast pile, traditional protective measures often involve temporary covering with wooden boards, steel mesh, and other simple measures, which are difficult to effectively adhere to the hole wall. Under the lateral pressure of the soil, the hole wall is prone to collapse, leading to the accumulation of soil and debris inside the hole, requiring additional cleaning work. This not only fails to prevent rainwater from entering the hole and causing water accumulation in the foundation pit, but also makes it difficult to prevent the safety risks of personnel and tools falling, seriously affecting construction efficiency and operational safety.

[0018] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0019] This utility model discloses a protective device for the construction of photovoltaic precast pile foundations.

[0020] This utility model provides, for example Figure 1-3 The protective device shown is for the construction of photovoltaic precast pile foundations. It includes a protective component 1, which includes a pile hole protective shell 2. A pile foundation positioning plate 3 is fixedly connected to the bottom of the cavity of the pile hole protective shell 2. A pile foundation positioning sleeve assembly 4 is inserted into the top of the pile foundation positioning plate 3. A limiting mechanism is provided between the pile foundation positioning sleeve assembly 4 and the pile foundation positioning plate 3. The inner side wall of the pile hole protective shell 2 has multiple first reserved openings 5, and threaded limiting rings 6 are fixedly connected to them. A positioning anchor rod 7 is inserted into each first reserved opening 5. A threaded sleeve 8 is fixedly connected to one end of the positioning anchor rod 7. Each threaded sleeve 8 is threadedly connected to the corresponding threaded limiting ring 6. The top of the pile hole protective shell 2 is provided with a positioning slot 9, which is engaged with a pile hole protective cover 10. The inner side wall of the pile hole protective cover 10 is provided with a second reserved opening 11, which is sleeved with the outer side wall of the pile foundation positioning sleeve assembly 4. The bottom of the pile hole protective cover 10 is provided with a support and reinforcement mechanism. The outer side wall of the pile hole protective cover 10 is fixedly connected with a limit ring 12. The pile hole protective shell 2 and the limit ring 12 are provided with corresponding first limit threaded openings 13 around their surfaces, and are threadedly connected with first limit threaded pins 14. The protective assembly 1 provides all-round protection for the construction of photovoltaic precast piles. The system integrates pile positioning and pile hole protection functions, avoiding the drawbacks of traditional decentralized protection. The pile hole protection shell 2 wraps around the pile hole sidewall, effectively preventing pile hole collapse during construction and blocking rainwater and debris from entering the pile hole, preventing water accumulation from affecting construction. The pile foundation positioning plate 3 provides the installation foundation for the pile foundation positioning sleeve assembly 4, ensuring accurate positioning of the positioning sleeve assembly. The pile foundation positioning sleeve assembly 4 limits and fixes the precast pile, preventing tilting during construction and improving the verticality of the pile foundation installation. The limiting mechanism ensures a stable connection between the positioning sleeve assembly and the positioning plate. To ensure stability and prevent displacement due to construction vibration, the positioning anchor 7, through the engagement of the threaded sleeve 8 and the threaded limiting ring 6, penetrates deep into the surrounding soil, enhancing the fixation of the pile hole protective shell and preventing it from shifting or tipping over. Compared to traditional structures without anchors, this significantly improves protective stability. The pile hole protective cover 10 covers the top of the pile hole, effectively preventing personnel and tools from falling into the pile hole and eliminating safety hazards. The positioning latch 9, in conjunction with the limiting ring 12, ensures that the protective cover is precisely engaged with the top of the protective shell. The first limiting threaded pin 14 locks in place through the threaded opening, further securing the protective shell. The cover is designed to prevent it from falling off due to external forces such as strong winds. The second reserved opening 11 is used to adapt to the positioning sleeve assembly, which does not affect the construction of the pile body and ensures the sealing effect of the protective cover. The supporting and strengthening mechanism enhances the load-bearing capacity and stability of the protective cover, prevents the protective cover from being deformed under pressure, and ensures that the protective cover is always effective in protection during the construction process. Compared with traditional simple protective covers, the safety and durability are significantly improved. This solves the problems in the traditional photovoltaic precast pile foundation construction process, such as the pile body is prone to tilting, the pile hole lacks protection and is prone to collapse and water accumulation, and there is also the risk of personnel falling, which affects efficiency and safety. To ensure a secure connection between the pile foundation positioning sleeve assembly and the positioning plate, and to prevent displacement, such as... Figure 2The limiting mechanism includes a U-shaped limiting seat 15, a limiting plate 16, a second limiting threaded opening 17, and a second limiting threaded pin 18. The top two ends of the pile foundation positioning disc 3 are fixedly connected to the U-shaped limiting seat 15. The side walls of both ends of the pile foundation positioning sleeve assembly 4 are fixedly connected to the limiting plate 16. The limiting plates 16 at both ends engage with the corresponding U-shaped limiting seats 15. The surfaces of the U-shaped limiting seats 15 and the limiting plates 16 at both ends are provided with second limiting threaded openings 17, and are threadedly connected with second limiting threaded pins 18. By engaging the U-shaped limiting seats 15 with the limiting plates 16, the positioning sleeve assembly and the positioning disc are quickly positioned, ensuring that both are coaxial and avoiding horizontal offset. The second limiting threaded pins 18 are used to lock the two together through the threaded openings, ensuring a stable connection during construction vibration without relative displacement. The threaded connection design facilitates disassembly and assembly, adapts to the replacement of positioning sleeve assemblies of different specifications, improves operational convenience, and ensures the positioning accuracy of the pile.

[0021] To enhance the support stability of the pile head protective cover and prevent deformation, such as Figure 2 and 3 As shown, the support and reinforcement mechanism includes an annular support bracket 19, an outer support ring 20, an internal threaded ring 21, and an arc-shaped internal threaded seat 22. The annular support bracket 19 is fixedly connected to the top of the inner side wall of the pile hole protective shell 2. The outer support ring 20 is fixedly connected to the bottom outer ring of the pile mouth protective cover 10. The internal threaded ring 21 is fixedly connected to the bottom inner ring of the pile mouth protective cover 10. The arc-shaped internal threaded seats 22 are fixedly connected to the side walls of both ends of the pile foundation positioning sleeve assembly 4. The bottom of the outer support ring 20 is engaged with the annular support bracket 19. The bottom of the internal threaded ring 21 is threadedly connected to the arc-shaped internal threaded seats 22 at both ends. The annular support bracket 19 and the outer support ring 20 cooperate to provide stable support for the outer ring of the protective cover and distribute the pressure on the protective cover. The internal threaded ring 21 is threadedly connected to the arc-shaped internal threaded seat 22 to fix the protective cover from the inner ring, forming a double support structure inside and outside. This significantly enhances the load-bearing capacity and stability of the protective cover, avoids deformation of the protective cover due to pressure or external impact, and ensures long-term effective protection of the protective cover. To adapt to different specifications of precast piles and improve positioning accuracy, such as Figure 1-3As shown, the pile foundation positioning sleeve assembly 4 includes a first positioning sleeve 23 and a second positioning sleeve 24, which are interlocked. Multiple first limiting plates 25 are fixedly connected to the side walls at both ends of the first positioning sleeve 23, and multiple second limiting plates 26 are fixedly connected to the side walls at both ends of the second positioning sleeve 24. A corresponding third limiting threaded opening 27 is provided between each first limiting plate 25 and each second limiting plate 26, and a third limiting threaded rod 28 is threadedly connected to it. The inner side walls of the arc-shaped internal threaded seats 22 at both ends are respectively connected to the corresponding first positioning sleeve 23 or second positioning sleeve 24. The outer wall of the 4 is fixedly connected, and the inner wall of the first positioning sleeve 23 and the second positioning sleeve 24 is fixedly connected with a rubber buffer isolation pad 29. By using the set first positioning sleeve and the second positioning sleeve to engage, the spacing of the limiting plate is adjusted and locked with a threaded rod, which can adapt to precast piles of different diameters without replacing the entire positioning assembly, thus improving adaptability. The set rubber buffer isolation pad 29 reduces the rigid collision between the pile body and the positioning sleeve, avoids damage to the surface of the pile body, and enhances the fit between the positioning sleeve and the pile body, preventing the pile body from shaking during construction, and further improving the verticality of the pile foundation installation. To enhance the stability of the protective device and prevent displacement or tipping, such as Figure 1 and 2 As shown, multiple supporting anchors 30 are fixedly connected to the bottom of both the pile hole protective shell 2 and the pile foundation positioning plate 3. These anchors penetrate deep into the underground soil of the construction site, forming multi-point fixation. This enhances the overturning resistance of the pile hole protective shell and the positioning plate, preventing displacement or collapse of the protective device due to external forces such as vibration and wind during construction. The distributed design of the multiple anchors ensures uniform fixing force, further improving the stability of the pile hole protective shell and providing a reliable foundation for pile construction and pile hole protection. To improve the corrosion resistance and durability of protective devices and adapt them to outdoor environments, such as Figure 1-3 As shown, the inner wall of the pile hole protective shell 2 is coated with an arc-sprayed aluminum coating, and the outer wall is coated with a polyurea elastomer coating. The outer surfaces of the first positioning sleeve 23 and the second positioning sleeve 24 are provided with a zinc-nickel alloy electroplating layer. The outer surface of the pile hole protective cover 10 is coated with a fluorocarbon coating. The combination of the arc-sprayed aluminum coating and the polyurea elastomer coating enhances the corrosion resistance and wear resistance of the protective shell, resists soil erosion and rain erosion, and extends its service life. The zinc-nickel alloy electroplating layer improves the rust resistance of the positioning sleeve and adapts to humid construction environments. The fluorocarbon coating has excellent weather resistance and prevents the protective cover from aging due to sun and rain.

Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
