Description

Technical Field

[0001] This utility model relates to the field of photovoltaic panel installation technology, and more specifically, to a prefabricated pile foundation for photovoltaic panel installation. Background Technology

[0002] Currently, the foundation structure of photovoltaic panel supports mostly uses cast-in-place concrete piles or directly driven steel piles. Cast-in-place concrete piles require on-site formwork, pouring, and curing, resulting in a long construction period and limitations imposed by environmental conditions; while traditional steel piles, although faster to install, have the following problems:

[0003] Insufficient connection stability: The embedded steel plates of the steel piles and the upper support are mostly rigidly welded, making it difficult to adjust the levelness and easily leading to deviations in the tilt angle of the photovoltaic panels during installation;

[0004] Weak pull-out resistance: The anchoring force between the pile and the soil depends on a single ground anchor structure, which is prone to displacement in soft soil or under strong wind conditions.

[0005] Poor corrosion resistance and durability: Exposed parts of the steel piles are prone to rust and require frequent maintenance;

[0006] Inadequate concrete filling: Existing concrete pouring processes for pile foundations are prone to creating voids, affecting overall strength. Utility Model Content

[0007] The purpose of this utility model is to overcome the shortcomings of the existing technology and provide a prefabricated pile foundation for photovoltaic panel installation to solve the above-mentioned shortcomings.

[0008] To achieve the above objectives, the technical solution provided by this utility model is as follows:

[0009] A precast pile foundation for photovoltaic panel installation includes a steel column, an outer sleeve, and an embedded steel plate. The lower end of the steel column is provided with a ground anchor wing plate and a conical ground anchor. The outer wall of the conical ground anchor is provided with threaded blades. The lower surface of the embedded steel plate is fixed with reinforcing bars, which are inserted into the steel column. The outer sleeve is fitted outside the steel column, and the inner wall of the outer sleeve is provided with reinforcing anchors.

[0010] Preferably, the steel column is a hollow round steel bar with internally inserted reinforcing bars, and the outer wall of the steel column is provided with a cross-shaped reinforcing plate, with concrete through holes opened between the reinforcing plate and the steel column.

[0011] Preferably, the lower surface edge of the embedded steel plate is provided with a sealing ring, which is sleeved with the upper end of the outer sleeve; a cross bracket is provided on the embedded steel plate, and a spherical groove is provided in the center of the cross bracket, with an installation plate provided in the spherical groove.

[0012] Preferably, a spherical hinge block is fixedly connected to the center of the lower surface of the mounting plate.

[0013] Preferably, an adjusting screw is hinged to the lower surface of the mounting plate, the adjusting screw passes through and engages with the embedded steel plate, and the tilt angle of the embedded steel plate is changed by rotating the adjusting screw.

[0014] Preferably, the outer casing is a corrosion-resistant pipe, and the reinforcing anchors and reinforcing plates are staggered.

[0015] Compared with the prior art, the technical solution provided by this utility model has the following advantages:

[0016] This utility model features modular assembly of prefabricated steel columns and outer sleeves, eliminating the need for on-site welding and shortening the construction period. Conical ground anchors and threaded blades enable rapid driving, adapting to complex geological conditions such as hard soil and frozen soil. Concrete overflows from the through-hole, creating a "rivet effect" that enhances the pile's pull-out resistance. Cross-shaped reinforcing plates and staggered reinforcing anchors improve the pile foundation's bending resistance. A spherical hinge block, in conjunction with an adjusting screw, allows for adjustment of the pre-embedded steel plate's tilt angle, ensuring photovoltaic panel installation accuracy. The outer sleeve is treated with anti-corrosion coating, and the internal concrete isolates the steel column from corrosive media, extending its service life. Attached Figure Description

Detailed Implementation

[0023] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] To further understand the content of this utility model, a detailed description of this utility model will be provided in conjunction with the accompanying drawings.

[0025] Combination Figures 1-5 The present invention relates to a prefabricated pile foundation for photovoltaic panel installation, comprising a steel column 1, an outer sleeve 2 and a pre-embedded steel plate 3. The lower surface of the pre-embedded steel plate 3 is fixedly connected with a reinforcing bar 31, which is inserted into the steel column 1. The outer sleeve 2 is fitted onto the outside of the steel column 1.

[0026] Specifically, the lower end of the steel column 1 is provided with a ground anchor wing plate 11, and the lower surface of the ground anchor wing plate 11 is provided with a conical ground anchor 12. The outer wall of the conical ground anchor 12 is provided with threaded blades to assist the conical ground anchor 12 in being driven into the ground. The steel column 1 is a hollow circular steel structure. The internal hollow structure of the steel column 1 is inserted with the reinforcing bar 31. A reinforcing plate 13 is connected to the outer wall of the steel column 1. The reinforcing plate 13 is distributed in a cross shape around the steel column 1. Concrete penetration holes 14 are opened on both the steel column 1 and the reinforcing plate 13. The concrete passes through the concrete penetration holes 14, which increases the firmness of the bond between the steel column 1 and the concrete. The reinforcing bar 31 can squeeze the concrete inside the steel column 1, so that the concrete overflows from the inside of the steel column 1 through the concrete penetration holes 14, increasing the concrete pressure inside the outer sleeve 2 and further filling the gap inside the outer sleeve 2.

[0027] More specifically, a sealing ring 32 is provided on the edge of the lower surface of the embedded steel plate 3. The sealing ring 32 is sleeved with the upper end of the outer sleeve 2 to seal the injected concrete. A cross bracket 33 is provided on the embedded steel plate 3. A spherical groove 331 is provided in the center of the cross bracket 33. An installation plate 34 is provided in the spherical groove 331. A spherical hinge block 341 is fixedly connected to the center of the lower surface of the installation plate 34. The spherical hinge block 341 is movably connected to the spherical groove 331. The installation plate 34 passes through... The spherical hinge block 341 moves in the spherical groove 331, changing the tilt angle of the mounting plate 34. The lower surface of the mounting plate 34 is hinged with an adjusting screw 35. The upper end of the adjusting screw 35 is fixedly connected to the mounting plate 34 through the spherical hinge seat 351. The adjusting screw 35 passes through the upper end face of the embedded steel plate 3, and the adjusting screw 35 engages with the upper end face of the embedded steel plate 3. Rotating the adjusting screw 35 controls the position of one side of the embedded steel plate 3 to rise or fall, which is used to adjust and fix the angle of the embedded steel plate 3.

[0028] It should be noted that the outer sleeve 2 is a corrosion-resistant pipe, and the inner wall of the outer sleeve 2 is provided with reinforcing anchors 21. There are four rows of reinforcing anchors 21, and the reinforcing anchors 21 are staggered with the reinforcing plate 13. During installation, the outer sleeve 2 is inserted from the upper end of the steel column 1 until the lower end of the outer sleeve 2 abuts against the ground anchor wing plate 11. Concrete is poured into the outer sleeve 2 and the steel column 1 until the concrete fills the outer sleeve 2 and the steel column 1. Before the concrete hardens, the reinforcing bar 31 is inserted into the steel column 1.

[0029] Working process: The conical ground anchor 12 at the lower end of the steel column 1 is screwed into the soil layer. The threaded blades enhance the anchoring force, and the ground anchor wing plate 11 limits the sinking depth. The outer sleeve 2 is inserted from the top of the steel column 1 until it contacts the ground anchor wing plate 11. The reinforced anchor 21 and the reinforced plate 13 are staggered to improve the concrete bonding force. Concrete is poured into the cavity between the outer sleeve 2 and the steel column 1. The reinforcing bar 31 is inserted into the steel column 1 to squeeze the concrete, causing it to overflow from the concrete through hole 14 and fill the gap of the outer sleeve 2. The sealing ring 32 seals the top of the outer sleeve 2 to prevent concrete leakage. The adjusting screw 35 is rotated, and through the cooperation of the spherical hinge block 341 and the spherical groove 331, the mounting plate 34 is tilted to achieve fine adjustment of the horizontality of the embedded steel plate 3. After the concrete cures, a composite pile is formed, and the steel column 1, the outer sleeve 2 and the concrete share the load.
