DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] See also Figure 1-5 The utility model provides an embodiment: a photovoltaic module large slope installation limit mechanism, comprising a base 1,

[0021] Two groups of brackets 2 are installed at the rear end of the base 1, and a photovoltaic module 3 is rotatably installed on the upper side of the front end of the base 1. The rear end of the photovoltaic module 3 is connected to the upper ends of the two groups of brackets 2. Two groups of fixing blocks 4 are fixedly installed on the left and right sides of the base 1. Limiting components are arranged in the four groups of fixing blocks 4. The device is to insert the four groups of fixing blocks 4 on the left and right sides of the base 1 into a preset pit, and then bury the pit. After the limiting components are opened, the four groups of fixing blocks 4 are tightly fixed in the soil, thereby achieving the limit fixing of the base 1 and the photovoltaic module 3 on the slope.

[0022] Furthermore, the limiting assembly includes a first rotating shaft 5, which is installed in the fixed block 4 through a thread, a second rotating shaft 6 is inserted into the lower end of the first rotating shaft 5, and a spiral shaft 7 is arranged on the outer wall of the lower end of the second rotating shaft 6. A groove 8 is opened in the lower end of the fixed block 4, and a spiral turntable 9 is fixedly installed on the outer wall of the lower end of the first rotating shaft 5. Four groups of plug rods 10 are movably installed in the fixed block 4, and the upper sides of the four groups of plug rods 10 are meshed with the lower side of the spiral turntable 9. This structure rotates the first rotating shaft 5 and the second rotating shaft 6 respectively, and the second rotating shaft 6 rotates and moves downward to insert the spiral shaft 7 into the soil, and the first rotating shaft 5 drives the spiral turntable 9 to rotate to slide the four groups of plug rods 10 out and insert them into the soil, so that the front, back, left, right and lower end of the fixed block 4 can be reinforced in the ground, thereby improving the fastening and anti-falling effect of the fixed block 4 installed on the ground.

[0023] Furthermore, the lower end of the second rotating shaft 6 and the opposite end of the four groups of insertion rods 10 are both tapered, and the four groups of insertion rods 10 are located on the four sides of the fixed block 4, front, back, left, and right. This structure facilitates the lower end of the second rotating shaft 6 and the four groups of insertion rods 10 to break through the soil and insert into the soil according to the shape of the lower end of the second rotating shaft 6 and the opposite end of the four groups of insertion rods 10, thereby improving the convenience of inserting the four groups of insertion rods 10 and the lower end of the second rotating shaft 6 into the soil.

[0024] Furthermore, eight groups of slide grooves 11 are opened in the fixed block 4, and the eight groups of slide grooves 11 are in contact with the four groups of plug rods 10. Two groups of sliders 12 are fixedly installed at the opposite ends of the four groups of plug rods 10. The eight groups of sliders 12 slide in the eight groups of slide grooves 11. This structure limits the four groups of plug rods 10 when they slide in the fixed block 4 by sliding the eight groups of sliders 12 in the eight groups of slide grooves 11, thereby preventing the four groups of plug rods 10 from separating from the lower side of the spiral turntable 9.

[0025] Furthermore, a first anti-blocking pad 13 and a second anti-blocking pad 14 are respectively provided on the front, back, left, right and right sides of the fixed block 4 and at the opening of the lower end of the groove 8. The lower end of the second rotating shaft 6 and the spiral shaft 7 are inserted into the first anti-blocking pad 13. This structure blocks the opening of the groove 8 and the opening on the fixed block 4 through the first anti-blocking pad 13 and four groups of second anti-blocking pads 14 to prevent soil from entering the groove 8 and the fixed block 4.

[0026] Furthermore, the four groups of second anti-blocking pads 14 are all provided with a right cross-shaped gap, and the opposite ends of the four groups of insertion rods 10 are fitted with the four groups of second anti-blocking pads 14. According to the shape of the four groups of second anti-blocking pads 14, this structure enables the right cross-shaped gap in the second anti-blocking pads 14 to be broken when the insertion rod 10 slides out, and conversely, when the insertion rod 10 slides into the fixed block 4, the right cross-shaped gap of the second anti-blocking pad 14 is closed.

[0027] Working principle: When the base 1 is fixed, Figure 1 , Figure 3 , Figure 4 and Figure 5 As shown, four groups of fixed blocks 4 are placed in a preset earth pit, and then the earth pit is buried. After rotating the second rotating shaft 6, the second rotating shaft 6 rotates and moves downward in the first rotating shaft 5, and the spiral shaft 7 at the lower end of the second rotating shaft 6 slides out of the groove 8 and inserts into the soil. Then the first rotating shaft 5 is rotated, and the rotation of the first rotating shaft 5 drives the spiral turntable 9 to rotate. The rotation of the spiral turntable 9 drives the four groups of plug rods 10 to slide out of the fixed block 4, and when the four groups of plug rods 10 slide out, they break through the regular cross-shaped gaps on the four groups of second anti-blocking pads 14 and slide out. Then the four groups of plug rods 10 slide out and are inserted into the soil, and the fixed block 4 can be fixed in the protrusion. The above is the entire working principle of the utility model.

[0028] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention.
