Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaic mounting frames, in particular to a wind-resistant photovoltaic mounting frame. Background Art

[0002] Solar photovoltaic system, also known as photovoltaic, refers to the facilities that use the photovoltaic effect of photovoltaic semiconductor materials to convert solar energy into direct current electricity. The core of photovoltaic facilities is solar panels. The semiconductor materials used for power generation are mainly: monocrystalline silicon, polycrystalline silicon, amorphous silicon and cadmium telluride. As countries have been actively promoting the application of renewable energy in recent years, the photovoltaic industry has developed rapidly.

[0003] With the development of solar energy application technology, photovoltaic power generation has received more and more attention and application. The solar photovoltaic bracket is composed of a bracket and a solar panel laid on the bracket.

[0004] The wind is stronger at high altitudes. When encountering strong winds above level 5, the positive airflow or the airflow from bottom to top that the solar photovoltaic panels are subjected to can easily blow the photovoltaic panels off the mounting frame, posing a great safety hazard.

[0005] For example, the prior art Chinese patent publication number "CN117040389 A" provides a photovoltaic module mounting frame, including a supporting base plate, a supporting base frame, a bottom mounting platform and a photovoltaic module mounting mechanism, the supporting base plate is arranged under the supporting base frame, the supporting base frame is an inverted U-shaped structure, fixed plates are respectively arranged at both ends of the bottom of the supporting base frame, the bottom mounting platform is installed on the upper end surface of the supporting base frame, and the photovoltaic module mounting mechanism is installed on the bottom mounting platform.

[0006] The device has a novel structural design, low overall production cost, and is convenient for later disassembly, assembly and maintenance. It can also adjust the angle and position of photovoltaic modules, thereby improving photovoltaic power generation efficiency. The device has good overall stability, strong wind and earthquake resistance, and a long service life.

[0007] The existing wind-resistant photovoltaic mounting racks have a relatively simple supporting structure at the bottom when encountering strong winds, and lack a good supporting structure. Moreover, the installation and fixation at the bottom is not stable enough, and the ground contact range of the bottom cannot be adjusted and expanded, resulting in the bottom of the mounting rack being unbalanced and unstable. At the same time, there is a lack of resistance and relief for the direct impact of wind flow around the photovoltaic panel installation position, which can easily blow the photovoltaic panel up and fall. Utility Model Content

[0008] The purpose of the utility model is to solve the shortcomings of the prior art that the supporting structure of the bottom end of the mounting frame is relatively simple and lacks a good supporting structure. In addition, the installation and fixation of the bottom end is not stable enough, and the ground contact range of the bottom end cannot be adjusted and expanded, resulting in the bottom end of the mounting frame being not balanced and stable enough. A wind-resistant photovoltaic mounting frame is proposed to solve the problems.

[0009] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0010] A wind-resistant photovoltaic mounting rack is designed, comprising a base, an adjusting groove is opened inside the base, a stabilizing plate is slidably inserted inside the adjusting groove, a first connecting hole is opened at the outer end of the stabilizing plate, a bolt passes through the inside of the first connecting hole, a sliding groove is opened at the top of the adjusting groove and at the top of the base, a connecting rod is fixed to the top of the inner end of the stabilizing plate, the connecting rod slides through the sliding groove, a nut is connected to the surface of the connecting rod and at the top of the sliding groove, a supporting column is fixed in the middle of the base, a connecting sleeve is slidably sleeved on the surface of the support column, a supporting rod is fixed to the bottom end of the surface of the connecting sleeve obliquely downward, a retaining ring is fixed to the top edge of the base, a limiting ring is fixed to the top of the retaining ring, and a first fan blade is fixed to the surface of the connecting sleeve and at the top of the support rod.

[0011] Furthermore, a support plate is fixed to the top of the support column, a rotating ring is slidably provided on the edge of the support plate, a rotating groove is opened on the inner side of the rotating ring, the edge of the support plate is slidably inserted into the rotating groove, a second fan blade is fixed on the outer side of the rotating ring, an electric telescopic rod is installed on the top of the support plate, and a mounting plate is provided on the top of the electric telescopic rod.

[0012] Furthermore, the adjustment groove is a rectangular groove structure, and is horizontally arranged and distributed in a cross shape around the base. The sliding groove is a long strip groove structure, and its length is less than the length of the adjustment groove.

[0013] Furthermore, the first connecting hole is a threaded hole structure, the bolt is vertically arranged, and the connecting rod is a threaded rod structure and is vertically arranged.

[0014] Furthermore, the support column is a cylindrical structure and is vertically arranged, the connecting sleeve is a round sleeve structure, and the bottom end of the support rod slides against the side of the retaining ring.

Therefore, the direct blowing wind force can be resisted and unloaded, reducing the blowing of strong wind on the photovoltaic panel and preventing the photovoltaic panel from being blown over and falling.
