Technical Field

[0001] The utility model relates to the fields of structural engineering technology and new energy photovoltaic technology, in particular to a prestressed self-locking clip anchor fastening mechanism and a flexible photovoltaic bracket. Background Art

[0002] Various policies have promoted the rapid development of the photovoltaic industry. With the advancement of development, the available land resources such as deserts, plains and mountains are gradually reduced. In order to solve the contradiction of photovoltaic land use, flexible photovoltaic brackets came into being. The brackets fasten the photovoltaic panels on the steel strands by tensioning the prestressed steel strands between two supports, so as to achieve a large span across fish ponds, rivers, canyons, ravines and other unfavorable terrains. It is suitable for a variety of landforms and has become an important direction of technical innovation.

[0003] Usually, steel strands are used as connecting components between the side columns and the side anchor foundations of flexible photovoltaic brackets, also known as inclined cables. When using clip anchors as matching anchors, the clip anchors must first be fixed to the steel strands to provide support points for applying tension. However, there are problems in the process of fixing the clip anchors, that is, it is easy to generate a large thrust force, making it difficult for the tensioning machine to provide an effective fixing point during construction; at the same time, the clip teeth are easy to loosen during transportation and installation, significantly reducing construction efficiency.

[0004] In summary, the utility model is committed to solving the challenges of eliminating reaction force and preventing loosening during the fixing process of the inclined cable clip anchor of the flexible photovoltaic bracket, as well as the inconvenient installation of the inclined steel cable. By adopting lower cost and simplified construction technology, the utility model only needs to occupy a smaller working space to successfully solve the problem of fixing and installing the clip anchor on the inclined cable.

[0035] Example 1

[0036] Reference Figure 1 , which is the first embodiment of the utility model, and which provides a prestressed self-locking clip anchor fastening mechanism, which can achieve the effect of eliminating reaction force and preventing loosening during the construction process of the clip anchor fixing of the flexible photovoltaic support inclined cable, and comprises a clip anchor fastening unit 100, which comprises an adjustment component 101, an inclined cable 102 arranged on the adjustment component 101, a first anchor 103 arranged on the inclined cable 102, a second anchor 104 installed at one end of the first anchor 103, and a pad 105 arranged at one end of the first anchor 103;

[0037] The first anchor 103 comprises a first anchor cup 103a installed on the surface of the inclined cable 102, and a first clip 103b installed in the first anchor cup 103a.

[0038] Specifically, the adjustment assembly 101 includes a front end plate 101a, a side baffle 101b arranged on one side of the front end plate 101a, a rear end plate 101c arranged at one end of the side baffle 101b, a bottom support plate 101d connected to the front end plate 101a, a triangular stiffening rib 101e installed at one end of the front end plate 101a, and a tensioning machine 101f installed on the surface of the rear end plate 101c.

[0039] Furthermore, the bottom support plate 101d is not only fixedly connected to the front end plate 101a, but also fixedly connected to the side baffle plate 101b and the rear end plate 101c.

[0040] The front end plate 101a is provided with a notch 101a-1.

[0041] Preferably, the triangular stiffening ribs 101e are fixedly connected to the front end plate 101a, with four in total, and are also fixedly connected to the side baffles 101b and the rear end plate 101c.

[0042] Furthermore, the pad 105 is installed at one end of the first anchor 103; wherein the pad 105 is provided with three through holes.

[0043] The stay cable 102 passes through the through hole of the pad 105 and is then installed inside the tensioning machine 101f.

[0044] More preferably, the first anchor 103 includes a first anchor cup 103a installed on the surface of the inclined cable 102, and a first clip 103b installed in the first anchor cup 103a; the second anchor 104 includes a second anchor cup 104a installed on the surface of the inclined cable 102, and a second clip 104b installed in the second anchor cup 104a.

[0045] In summary, when in use, the inclined cable 102 is passed through the notch 101a-1 on the front end plate 101a, the through hole of the pad 105, and the first anchor 103 and the second anchor 104, and extended into the tensioning machine 101f, keeping the pad 105 and the notch 101a-1 in a vertical state, and then the second anchor 104 is placed on the second anchor 104, and the first anchor 103 is not placed with a clip, and the tensioning machine 101f starts the first push, and the first anchor cup 103a of the front end of the tensioning machine 101f pushes the force on the second clip 104b, and the second clip 104b is placed on the second anchor 104. 4b cuts into the inclined cable 102. When the tensioning machine 101f removes the thrust force, the first anchor 103 is placed in the first clamp 103b. The tensioning machine 101f starts the second tensioning. At this time, the inclined cable 102 will undergo elastic deformation, and the prestress will be applied to the inclined cable 102. When the tensioning machine 101f removes the tensioning force, the first clamp 103b is driven to cut into the inclined cable 102 under the action of the rebound force of the elastic deformation of the inclined cable 102, and the first anchor cup 103a is also driven to apply a tightening force to the second clamp 104b, locking the second clamp 104b tightly. At the same time, the steel strand between the first anchor 103 and the second anchor 104 forms a prestress, and a pulling force in the opposite direction is formed between the first anchor 103 and the second anchor 104, so as to maintain the fastening between the two and achieve an anti-loosening effect, so that the anchor will not fall off the inclined cable 102 no matter from which direction the force is applied. Repeat the above operation at the other end of the inclined cable 102 to complete the installation of the first anchor 103 and the second anchor 104 at both ends of the inclined cable.

[0047] Reference Figure 3 , which is the second embodiment of the utility model. Different from the previous embodiment, this embodiment provides a notch 101a-1, which includes a notch 101a-1 opened on the front end plate 101a.

[0048] Specifically, the slot 101 a - 1 is larger than the backing plate 105 , and the backing plate 105 can pass through the slot 101 a - 1 .

[0049] Furthermore, the backing plate 105 can be rotated 90° to move the backing plate 105 and withdraw it from the adjustment assembly 101 through the provided notch 101a-1.

[0050] In summary, when in use, the pad 105 is rotated 90°, and then moved to withdraw the pad 105 from the slot 101a - 1 , thereby completing the removal of the pad 105 from the inside of the adjustment assembly 101 .
