Description

Technical Field

[0001] This utility model belongs to the field of anchorage technology for photovoltaic brackets, and in particular relates to a combined anchorage suitable for flexible photovoltaic brackets. Background Technology

[0002] Flexible photovoltaic support systems are a new type of photovoltaic system developed in recent years. This system has advantages such as large span, high clearance, and low cost, and is widely used in complex terrain and ground anchor scenarios. The wedge-type single-hole stress anchor is a key component in prestressed concrete construction technology and is widely used in long-span railways, highway bridges, industrial plants, dams, nuclear reactor shells and other special buildings. With the popularization of flexible supports, their application in photovoltaic supports is also quite common.

[0003] Currently, the application of wedge-type anchors in flexible photovoltaic supports mainly involves tensioning with a single-hole prestressed anchor. However, in actual installation, this method fails to meet the prestress requirements of the anchor, often resulting in insufficient engagement between the wedge anchor and the steel strand, leading to anchor failure. Utility Model Content

[0004] The purpose of this invention is to provide a combined anchor suitable for photovoltaic flexible supports, thereby solving the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model relates to a combined anchor suitable for photovoltaic flexible support, comprising a connecting seat and a limiting component. A guide sleeve is fixedly connected inside the connecting seat. A sliding groove is formed in the middle of the upper surface of the connecting seat, and the sliding groove communicates with the guide sleeve. Matching grooves are formed on both sides inside the connecting seat, and the matching grooves communicate with the guide sleeve. The limiting component includes limiting blocks, with two sets of limiting blocks respectively disposed within two sets of matching grooves and slidingly engaging with them. A matching spring is fixedly connected to one end of each limiting block, and one end of the matching spring is fixedly connected to the inner wall of the matching groove. An inclined groove is formed on one side of the limiting block, and a sliding shaft is slidably connected inside the inclined groove. A linkage frame is fixedly connected to one end of the sliding shaft, and the linkage frame is disposed on one side of the limiting block, with one end of the linkage frame disposed within the matching groove and slidingly engaging with it. Multiple sets of slots are formed inside the connecting seat, with the slots disposed on one side of the sliding grooves, and the linkage frame disposed within the slots and slidingly engaging with them.

[0007] A mating frame is fixedly connected to the upper surface of the connecting seat. An adjusting screw is threadedly connected to the inside of the mating frame. A linkage plate is rotatably connected to the circumference of the adjusting screw. The linkage plate is located below the mating frame. The bottom surface of the linkage plate is fixedly connected to one end of the linkage frame. A limit post is rotatably connected to one end of the adjusting screw. The limit post is located in a sliding groove and slides with the sliding groove.

[0008] Both the bottom end of the limiting post and the other end of the limiting block are fixedly connected to a clamping anchor, and the surface of the clamping anchor is provided with an anti-slip pad.

[0009] The upper surface of the connector is provided with a slot. The slot is rectangular and is located on the periphery of the mating frame. A protective cover is inserted into the slot. The height of the inner cavity of the protective cover is higher than the height of the adjusting screw.

[0010] A photovoltaic support column is fixedly connected to the bottom surface of the connecting seat, and a concrete base is fixedly connected to the bottom end of the photovoltaic support column.

[0011] This utility model has the following beneficial effects:

[0012] This invention, through the installation of a connecting seat, guide sleeve, and limiting assembly, allows the external steel strand to pass through the guide sleeve. Rotating the adjusting screw, with the assistance of the mating frame, moves the limiting post and linkage plate downwards. This causes the linkage frame to slide the sliding shaft within the inclined groove, stretching the mating spring and moving the limiting block within the mating groove. This allows the clamping anchor at one end of the limiting block to clamp and engage with the side of the steel strand, while the clamping anchor at the bottom of the limiting post clamps and engages with the upper surface of the steel strand, increasing the tightness of the engagement between the clamping anchor and the steel strand, forming a more stable anchoring structure. After the adjusting screw has rotated, the protective cover is inserted into the slot, placing the adjusting screw inside the protective cover to protect it, reduce environmental impact, and extend its service life.

[0023] Please see Figures 1-3As shown, this utility model is a combined anchor suitable for photovoltaic flexible support, including a connecting seat 102 and a limiting component 2. A guide sleeve 104 is fixedly connected inside the connecting seat 102. A sliding groove 107 is formed in the middle of the upper surface of the connecting seat 102, communicating with the guide sleeve 104. Matching grooves 108 are formed on both sides inside the connecting seat 102, communicating with the guide sleeve 104. The limiting component 2 includes limiting blocks 202, with two sets of limiting blocks 202 respectively disposed within the two sets of matching grooves 108 and slidingly engaging with them. One end of the limiting block 202 is fixedly connected to a cooperating spring 203. One end of the cooperating spring 203 is fixedly connected to the inner wall of the cooperating groove 108. A sloping groove 204 is opened on one side of the limiting block 202. A sliding shaft 208 is slidably connected inside the sloping groove 204. A linkage frame 207 is fixedly connected to one end of the sliding shaft 208. The linkage frame 207 is set on one side of the limiting block 202. One end of the linkage frame 207 is set in the cooperating groove 108 and slidably engages with the cooperating groove 108. Multiple sets of slots are opened inside the connecting seat 102. The slots are set on one side of the sliding groove 107. The linkage frame 207 is set in the slot and slidably engages with the slot.

[0024] A mating frame 105 is fixedly connected to the upper surface of the connecting seat 102. An adjusting screw 205 is threadedly connected to the inside of the mating frame 105. A linkage plate 206 is rotatably connected to the circumference of the adjusting screw 205. The linkage plate 206 is located below the mating frame 105. The bottom surface of the linkage plate 206 is fixedly connected to one end of the linkage frame 207. One end of the adjusting screw 205 is rotatably connected to a limiting post 201. The limiting post 201 is located in the slide groove 107 and slides with the slide groove 107.

[0025] The bottom end of the limiting post 201 and the other end of the limiting block 202 are both fixedly connected to the clamping anchor 209, and the surface of the clamping anchor 209 is provided with anti-slip pads.

[0026] The upper surface of the connector 102 is provided with a slot 103. The slot 103 is rectangular and is located on the periphery of the mating bracket 105. A protective cover 106 is inserted into the slot 103. The height of the inner cavity of the protective cover 106 is higher than the height of the adjusting screw 205.

[0027] A photovoltaic support column 101 is fixedly connected to the bottom surface of the connecting seat 102, and a concrete base 1 is fixedly connected to the bottom end of the photovoltaic support column 101.

[0028] It should be further explained that in actual use, the external steel strand is passed through the guide sleeve 104, and then the adjusting screw 205 is rotated. With the cooperation of the mating frame 105, it causes the limiting post 201 and the linkage plate 206 to move downwards. This, in turn, causes the linkage frame 207 to drive the sliding shaft 208 to slide within the inclined groove 204, stretching the mating spring 203. This causes the limiting block 202 to move within the mating groove 108, thereby causing the clamping anchor 209 at one end of the limiting block 202 to press against the side of the steel strand. The clamping and engaging mechanism allows the limiting post 201 to slide downwards within the groove 107, causing the clamping anchor 209 at its bottom end to clamp and engage with the upper surface of the steel strand. This improves the tightness of the engagement between the clamping anchor 209 and the steel strand, forming a more stable anchoring structure. After the adjusting screw 205 has rotated, the protective cover 106 is inserted into the slot 103, thereby placing the adjusting screw 205 within the protective cover 106 to protect the adjusting screw 205, reduce environmental impact, and extend its service life.

[0029] The distance that the adjusting screw 205 drives the limiting post 201 to move down is the same as the distance that the linkage frame 207 drives the sliding shaft 208 to slide in the inclined groove 204. Therefore, the clamping anchor 209 at the bottom of the limiting post 201 and the clamping anchor 209 at one end of the limiting block 202 can synchronously clamp and engage the steel strand.
