[0020] See also Figure 1-2 , Figure 1 This is a structural diagram of a frost-heaving resistant pile foundation for installing a photovoltaic support in a frozen soil area according to the first embodiment of the utility model. Figure 2 It is a cross-sectional schematic diagram of a frost-heaving resistant pile foundation for installing a photovoltaic support in a frozen soil area according to the first embodiment of the utility model.

[0021] The utility model provides an anti-frost heave pile foundation for installing a photovoltaic support in a frozen soil area: comprising a support rod 101 and an installation assembly 102, wherein the installation assembly 102 comprises a connecting rod 103, a first sleeve 104, a second sleeve 105, a slide 106, a mounting plate 107, a rotating member 108, a plug rod 109, a connecting plate 110, a motor 111, a fixing plate 112, a reinforcing rib 113, a ring 114, a threaded rod 115 and a cone 116. The above-mentioned solution solves the problem that when used in a frozen soil area, the foundation is easily affected by the seasonal ambient temperature, resulting in a positional displacement on the ground, thereby affecting the normal use of photovoltaics.

[0022] In this embodiment, the support rod 101 is used to support the photovoltaic panel to be installed.

[0023] Among them, the mounting plate 107 is fixedly connected to the support rod 101 and is located at the top of the mounting plate 107, the first sleeve 104 is arranged at the bottom of the mounting plate 107, the connecting rod 103 is fixedly connected to the first sleeve 104 and is located on one side of the first sleeve 104, the second sleeve 105 is fixedly connected to the connecting rod 103 and is located on one side of the connecting rod 103, the slide groove 106 is fixedly connected to the second sleeve 105 and is located on the inner side of the second sleeve 105, the insertion rod 109 is fixedly connected to the mounting plate 107 and is located at the bottom of the mounting plate 107, the insertion rod 109 is slidably connected to the slide groove 106 and is located on the inner side of the slide groove 106, and the rotating member 108 is arranged at At the top of the mounting plate 107, when installing the device, a hole is first made in the ground, and then the first sleeve 104 is slidably inserted into the ground for positioning. After positioning is completed, concrete is poured between the first sleeve 104 and the second sleeve 105. When the concrete is completely solidified, the insertion rod 109 is slidably inserted into the slide groove 106 to position and install the support rod 101. The foundation is reinforced by the first sleeve 104, the second sleeve 105 and concrete, and finally the photovoltaic panel is installed on the rotating component 108. The rotating component 108 can adjust the angle of the photovoltaic panel, which solves the problem that when used in frozen soil areas, the foundation is easily affected by the seasonal ambient temperature, resulting in position displacement of the foundation on the ground, thereby affecting the normal use of photovoltaics.

[0024] Secondly, the rotating component 108 includes a connecting plate 110, a motor 111 and a fixing plate 112. The connecting plate 110 is fixedly connected to the mounting plate 107 and is located on the top of the mounting plate 107.

The threaded rod 115 is threadedly connected to the first sleeve 104 and is located on one side of the first sleeve 104. The cone 116 is fixedly connected to the threaded rod 115 and is located on one side of the threaded rod 115. The threaded rod 115 is used to install the cone 116. When the first sleeve 104 is inserted into the ground, the cone 116 stabilizes the external position of the first sleeve 104 to facilitate positioning and installation.

[0027] When using the utility model of a frost heave pile foundation for installing a photovoltaic support in a frozen soil area, the support rod 101 is used to support the photovoltaic panel to be installed. When installing the device, the ground is first drilled, and then the first sleeve 104 is slidably inserted into the ground for positioning. After positioning, concrete is poured between the first sleeve 104 and the second sleeve 105. When the concrete is completely solidified, the insertion rod 109 is slid into the slide groove 106 to position and install the support rod 101. The foundation is reinforced by the first sleeve 104, the second sleeve 105 and concrete. Finally, the photovoltaic panel is installed on the rotating component 108. The rotating component 108 can adjust the angle of the photovoltaic panel, which solves the problem that when used in a frozen soil area, the foundation is easily affected by the seasonal ambient temperature, resulting in position displacement of the foundation on the ground, thereby affecting the normal use of photovoltaics.
