Description

Technical Field

[0001] This utility model belongs to the technical field of photovoltaic facilities, and specifically relates to a detachable concrete counterweight device for photovoltaic supports. Background Technology

[0002] To make full use of land, agricultural-solar complementary and pastoral-solar complementary technologies have been widely applied in the photovoltaic power generation field. This means that while satisfying the needs of photovoltaic power generation, the land is preserved for planting crops and pasture by using high photovoltaic supports. This ensures the development of agriculture and animal husbandry while making full use of the sunlight resources above the land and promoting green development.

[0003] With the project in operation, the photovoltaic supports in the site have experienced varying degrees of settlement due to changes in foundation conditions, resulting in reduced foundation stability. At the same time, due to the high installation height of the photovoltaic supports, they also bear a large wind load, posing a risk of tipping over. Directly reinforcing the foundation would affect the planting of crops below. Utility Model Content

[0004] This invention provides a detachable concrete counterweight device for photovoltaic supports to solve the problem of poor stability of photovoltaic supports.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0006] A detachable concrete counterweight device for a photovoltaic support includes a first support plate group and a second support plate group for being sleeved onto the photovoltaic support rod, wherein the first support plate group is spaced apart and disposed below the second support plate group.

[0007] Multiple layers of counterweights are stacked between the first support plate group and the second support plate group. Each layer of counterweights includes multiple counterweight units, which are symmetrically arranged around the photovoltaic support pole.

[0008] Furthermore, both the first support plate group and the second support plate group include a pair of unit components. Each unit component includes a first strut segment, a collar segment, and a second strut segment connected in sequence. The collar segment of the two unit components is assembled to form a shape that matches the cross-sectional shape of the photovoltaic support rod. The first strut segment and the second strut segment are symmetrically arranged along the collar segment.

[0009] Furthermore, limit blocks are provided at the ends of both the first and second support rod segments that are furthest from the photovoltaic support rod.

[0010] Furthermore, the thickness of the collar segment is greater than the thickness of the first support segment and the second support segment, and the surfaces of one end of the collar segment, one end of the first support segment, and one end of the second support segment are all coplanar.

[0011] Furthermore, the first support plate assembly also includes a diagonal brace, one end of which is fixedly connected to the free ends of both the first support rod segment and the second support rod segment, and the other end is fixedly connected to the side wall of the collar segment.

[0012] Furthermore, the counterweight unit has a groove at the bottom and a protrusion at the top. When the upper and lower counterweights are stacked, the protrusion of the lower counterweight is inserted into the groove of the upper counterweight.

[0013] Furthermore, the counterweight block of the first layer is rotated 90 degrees around the center of the photovoltaic support rod compared to the counterweight block of the adjacent layer.

[0014] Furthermore, mounting rings are fixed to the outer edges of both the first support plate group and the second support plate group, and multiple pull ropes are also provided between the first support plate group and the second support plate group, with the two ends of the pull ropes respectively tied to the mounting rings.

[0015] The present invention can achieve the following beneficial effects:

[0016] 1. This application increases the weight of the photovoltaic support pole by setting a first support plate group and a second support plate group on the photovoltaic support pole, that is, by stacking several layers of counterweight blocks between the first support plate group and the second support plate group. This increases the weight of the photovoltaic support pole itself without affecting the planting of crops at the bottom of the photovoltaic support pole, thereby enhancing the anti-overturning ability of the photovoltaic support pole and improving the stability of the photovoltaic support.

[0017] 2. The limiting block can restrict the relative movement of the counterweight block relative to the first support plate group. The protrusions and grooves on the counterweight unit can restrict the relative movement between the counterweight units, thereby improving the placement stability of the counterweight block.

[0018] 3. Several pull ropes are installed between the first support plate group and the second support plate group, so that the friction between the first support plate group and the photovoltaic support rod and the friction between the second support plate group and the photovoltaic support rod can be used to resist the weight of the counterweight, thus making the safety factor of the counterweight device of this application higher.

[0026] 100. Photovoltaic support pole. Detailed Implementation

[0027] To facilitate understanding of this application, a more complete description will be provided below with reference to the accompanying drawings, which illustrate embodiments of the present application. However, the present application can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided so that the disclosure of this application will be thorough and complete.

[0028] like Figures 1 to 4 As shown, a detachable concrete counterweight device for photovoltaic support is used to install on photovoltaic support pole 100, including a first support plate group 1 and a second support plate group 2. Both the first support plate group 1 and the second support plate group 2 can be detachably sleeved on the outside of the photovoltaic support pole 100, and the first support plate group 1 is spaced below the second support plate group 2; multiple layers of counterweight blocks are stacked between the first support plate group 1 and the second support plate group 2, and each layer of counterweight blocks includes multiple counterweight units 3, which are symmetrically arranged around the photovoltaic support pole 100.

[0029] Setting up the first support plate group 1 can achieve suspended support for the multi-layer counterweight blocks, which can increase the weight of the photovoltaic support without affecting the planting of crops below, making the photovoltaic support more resistant to wind loads. At the same time, it also makes the photovoltaic support heavier, resulting in a greater amount of foundation settlement into the ground.

[0030] The first support plate assembly 1 and the second support plate assembly 2 each include a pair of detachable and splicable unit components 11. Each unit component 11 includes a first support rod segment 111, a collar segment 112, and a second support rod segment 113 connected in sequence. The collar segment 112 of the two unit components 11, when assembled, forms a shape that matches the cross-sectional shape of the photovoltaic support rod 100. In this embodiment, the collar segment 112 is semi-circular. After the collar segment 112 of the two unit components 11 is placed around the photovoltaic support rod 100, the two collar segments 112 are fixed using high-strength bolts, thus completing the installation of the first support plate assembly 1. The first support rod segment 111 and the second support rod segment 113 are symmetrically arranged along the collar segment 112 to support the counterweight.

[0031] The thickness of the collar segment 112 along the height direction of the photovoltaic support rod 100 is greater than the thickness of the first support segment 111 and the second support segment 113 along the height direction of the photovoltaic support rod 100. Furthermore, one end surface of the collar segment 112, one end surface of the first support segment 111, and one end surface of the second support segment 113 are all coplanar. By setting a thicker collar segment 112, the contact area between the collar segment 112 and the photovoltaic support rod 100 is increased, thereby increasing the friction between the collar segment 112 and the photovoltaic support rod 100, thus achieving stable support for the counterweight.

[0032] In addition, multiple mounting rings 13 are fixed to the outer edges of both the first support plate assembly 1 and the second support plate assembly 2. Multiple pull ropes 4 are also installed between the first support plate assembly 1 and the second support plate assembly 2, with both ends of the pull ropes 4 tied to the mounting rings 13. The pull ropes 4 form a single unit with the first support plate assembly 1 and the second support plate assembly 2, thus allowing the friction between the second support plate assembly 2 and the photovoltaic support rod 100 to resist the downward force of the counterweight.

[0033] Furthermore, the first support plate assembly 1 also includes a diagonal brace 12. One end of the diagonal brace 12 is fixedly connected to the free ends of both the first support rod segment 111 and the second support rod segment 113, and the other end is fixedly connected to the side wall of the collar segment 112. Thus, the diagonal brace 12, the first support rod segment 111, and the collar segment 112, or the diagonal brace 12, the second support rod segment 113, and the collar segment 112, are arranged to form a triangle to improve the load-bearing capacity of the first support plate assembly 1. Since the first support rod segment 111 and the second support rod segment 113 are cantilevered, they are prone to long-term deformation under the pressure of the counterweight. By setting the diagonal brace 12, the support strength and stability of the first support rod segment 111 and the second support rod segment 113 can be improved.

[0034] Limiting blocks 114 are provided at the ends of the first support rod section 111 and the second support rod section 113 away from the photovoltaic support rod 100. The limiting blocks 114 limit the position of the counterweight blocks, reducing the possibility of the counterweight blocks falling off the first support plate group 1 and the second support plate group 2. Each counterweight unit 3 has a groove 31 at the bottom and a protrusion 32 fixed at the top. When the upper and lower counterweight blocks are stacked, the protrusion 32 of the lower counterweight block is inserted into the groove 31 of the upper counterweight block. By setting the protrusion 32 and the groove 31, the counterweight blocks can be limited, making the counterweight blocks more stably placed on the first support plate group 1.

[0035] In this embodiment, the outer contour of the counterweight unit 3 is semi-circular, and each counterweight unit 3 has two symmetrically formed grooves 31 and two symmetrically arranged protrusions 32. Two counterweight units 3 are provided in each layer, and the counterweight blocks of one layer are rotated around the center of the photovoltaic support rod 100 relative to the counterweight blocks of the adjacent layers, thereby making the counterweight units 3 of the adjacent layers staggered, which can improve the overall splicing integrity of the counterweight units 3.

[0036] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
