Description

Technical Field

[0001] This utility model belongs to the field of pile foundation installation technology, and in particular relates to a pile foundation positioning device for mountain photovoltaic systems. Background Technology

[0002] With the rapid development of mountain photovoltaic power generation projects, the positioning and installation of pile foundations have become crucial factors affecting project efficiency and quality. Mountainous terrain is complex, and soil conditions are diverse, making traditional pile foundation construction equipment often unsuitable for different geological environments. Currently, common pile foundation positioning devices mostly employ mechanical drilling or direct driving, which, while meeting basic construction requirements, still face challenges in positioning accuracy and construction efficiency in complex terrain.

[0003] Currently, in hard strata, the traditional helical blade structure, due to its simple design, results in excessive insertion resistance, requiring not only higher driving torque but also easily causing equipment overload and drill bit wear. In loose soil, the lack of effective soil guidance and containment capacity frequently leads to soil backflow and repeated crushing during construction, severely impacting pile quality and construction efficiency.

[0004] To address these issues, we provide a pile foundation positioning device for mountain photovoltaic systems. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model is a pile foundation positioning device for mountain photovoltaic systems, comprising...

[0006] The base has a cylindrical cavity running vertically through its center.

[0007] A sliding cylinder, which is vertically slidably disposed on the inner wall of the base;

[0008] The spiral blades are coaxially rotatably disposed within the inner cavity of the slide cylinder, and their peripheral surfaces are in sliding fit with the inner wall of the slide cylinder.

[0009] A power source is used to drive the slide and the helical blade to move synchronously in the vertical direction and to drive the helical blade to rotate in the inner cavity of the slide;

[0010] The cross-section of the spiral blade is in the shape of multiple equally spaced funnels, including an inner inclined section close to the axis of rotation and an outer inclined section away from the axis of rotation, and a flared soil-containing cavity is formed between the inner inclined section and the outer inclined section.

[0011] The spiral blades are inclined upward relative to the axis of rotation and are arranged in the shape of a vertically downward arrow to reduce insertion resistance and improve the axial transport efficiency of the soil.

[0012] The present invention is further configured such that the diameter of the flared soil-containing cavity gradually increases from the bottom to the top of the soil inlet end to the soil outlet end along the rotation axis, and a stepped-expanding buffer surface is formed around it.

[0013] The present invention is further configured such that the angle α between the inner inclined segment and the rotation axis is in the range of 30° to 60°, and the angle β between the outer inclined segment and the rotation axis is in the range of 10° to α.

[0027] 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. Specific Implementation

[0028] Please see Figure 1 This utility model is a pile foundation positioning device for mountain photovoltaic, including a base 1, the center of which is set as a cylindrical cavity that runs vertically through the ground. Several support legs are evenly fixed on the bottom surface of the base 1, and the bottom surface of the support legs is provided with an anti-slip layer, so that the base 1 can be placed stably on the ground.

[0029] The slide cylinder 2 is vertically slidably installed on the inner wall of the base 1. The circumferential side of the bottom end of the slide cylinder 2 is beveled, and its top end is thin, similar to a blade, to facilitate its insertion into the soil. The top end is raised and gradually widens until it is the same as the outer diameter of the slide cylinder 2. The beveled edge is smoothly connected to the circumferential side of the slide cylinder 2 to reduce the resistance of the slide cylinder 2 entering the soil.

[0030] The spiral blade 3 is coaxially rotatably installed inside the slide cylinder 2. Its circumferential side is in contact with the inner wall of the slide cylinder 2. Rotating the rotating shaft of the spiral blade 3 can drive the spiral blade 3 to rotate, so as to spirally transport the soil at the bottom upward and drop it from the top of the slide cylinder 2, thereby drilling holes in the soil as preset positioning holes. The bottom end of the rotating shaft of the spiral blade 3 is fixed with a soil-breaking cone, which is set as a pointed end to facilitate insertion into the soil and reduce resistance.

[0031] A mounting plate 7 is fixed to the top of the slide cylinder 2;

[0032] The power source is used to drive the slide 2 and the helical blade 3 to move synchronously in the vertical direction, and to drive the helical blade 3 to rotate in the inner cavity of the slide 2.

[0033] The power source includes a servo motor 8 fixed on the surface of the mounting plate 7, whose output end is coaxially connected to the rotation shaft of the spiral blade 3. The servo motor 8 can drive the spiral blade 3 to rotate and transport soil.

[0034] It also includes an electric telescopic rod 9, whose fixed end and telescopic end are connected to the bottom of the base 1 and the top of the slide cylinder 2, respectively. The electric telescopic rod 9 drives the slide cylinder 2 to move downward and drill into the soil. The spiral blade 3 descends synchronously with the slide cylinder 2 to transport the soil at the bottom upward.

[0035] For further details, please refer to Figure 2-3 The cross-section of the spiral blade 3 is in the shape of multiple equally spaced funnels, including an inner inclined section 4 close to the axis of rotation and an outer inclined section 5 away from the axis of rotation. An flared soil cavity 6 is formed between the inner inclined section 4 and the outer inclined section 5. Compared with the conventional spiral blade 3, the inclined angle of its peripheral side is larger, resembling a funnel.

[0036] The spiral blade 3 is inclined upward relative to the axis of rotation and is set as a vertically downward arrow to reduce insertion resistance and improve the axial transport efficiency of soil. When the spiral blade 3 transports the soil upward, the loose soil is located inside the flared soil cavity 6. Its inner wall has the bearing capacity for the soil, which is equivalent to placing the soil in a funnel and transporting it upward, reducing the amount of soil falling back and improving the soil transport efficiency.

[0037] The diameter of the flared soil-bearing cavity 6 gradually increases from the bottom to the top of the soil inlet end to the soil outlet end along the rotation axis. Its outer periphery forms a stepped expansion buffer surface. The funnel-shaped spiral blades 3, when viewed from the bottom up, are multiple equally spaced conical plates, and their tips are located at the bottom, which helps to reduce the resistance of the spiral blades 3 in breaking the soil and reduce their wear.

[0038] The angle α between the inner inclined section 4 and the rotation axis is between 30° and 60°, and the angle β between the outer inclined section 5 and the rotation axis is between 10° and α. This limitation sets the flared soil-bearing cavity 6 into a bowl shape with the top tapering inward, which enhances its ability to hold and bear soil.

[0039] For further details, please refer to Figure 2 The base 1 and the top of the slide cylinder 2 are both designed with downward-sloping surfaces to guide the loose soil conveyed by the spiral blades 3. The top of the slide cylinder 2 is provided with an umbrella-shaped plate. The diameter of the bottom of the base 1 and the umbrella-shaped plate is larger than the diameter of the top. When the soil comes out from the top of the slide cylinder 2, it slides down the slope of the annular plate and falls to the ground away from the side of the slide cylinder 2. Some of the soil that falls to the side of the base 1 can also slide down the slope to prevent the soil from falling back into the excavated positioning hole and causing repeated work.
