Description

Technical Field

[0001] This utility model relates to the field of photovoltaic equipment technology, specifically a photovoltaic array windproof ground anchor fixing device. Background Technology

[0002] As a crucial component of solar power generation systems, the safe and stable operation of photovoltaic (PV) arrays directly impacts power generation efficiency and equipment lifespan. In outdoor environments, PV arrays often face challenges from strong winds and other severe weather conditions, thus requiring reliable fixing devices to enhance their wind resistance. Ground anchors, a common fixing method, are widely used in PV array installations. Their main function is to firmly secure the PV array's support structure to the ground, preventing displacement or overturning under wind forces.

[0003] Existing photovoltaic array ground anchor fixing devices have simple structures and limited gripping force. They are difficult to provide sufficient fixing strength under soft or complex geological conditions, resulting in poor wind protection. Secondly, soil can easily enter the device during installation, causing wear or blockage of components, affecting the service life and operational stability of the device. Some devices are also cumbersome to install, have poor adaptability, and are difficult to meet the installation requirements under different geological conditions. Utility Model Content

[0004] The purpose of this utility model is to provide a photovoltaic array windproof ground anchor fixing device, which solves the problems of photovoltaic array ground anchor fixing devices having simple structure, limited gripping force, and difficulty in providing sufficient fixing strength under soft or complex geological conditions, resulting in poor windproof effect. Secondly, soil is easy to enter the device during installation, causing wear or blockage of components, affecting the service life and operational stability of the device. Some devices also have a cumbersome installation process, poor adaptability, and difficulty in meeting the installation requirements under different geological conditions.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a photovoltaic array windproof ground anchor fixing device, comprising: a top block and a fixing hook, the bottom of the fixing hook being fixedly connected to the middle position of the top of the top block, and the fixing hook being used for fixing the photovoltaic array steel cable; the top block being movably connected to a connecting operating mechanism via a bearing; a windproof reinforcing mechanism being movably connected to the outside of the connecting operating mechanism; and a drill bit being fixedly connected to the connecting operating mechanism, the bottom of which is conical.

[0006] The aforementioned connecting operating mechanism includes a main rod, a control handle, a folding protective cover, and a return spring. The control handle is fixedly connected to the outside of the main rod, and a thread is provided in the middle of the surface of the main rod. There are two sets of folding protective covers and return springs, with the folding protective covers respectively fitted onto the outside of the return springs, and the return springs respectively fitted onto the outside of the main rod. The top and bottom of the two sets of return springs and folding protective covers are fixedly connected.

[0007] As described above, the top end of the main rod is movably connected to the bottom of the top block via a bearing, and the bottom end of the main rod is fixedly connected to the middle position of the top end of the drill bit.

[0008] The aforementioned windproof reinforcement mechanism includes a connecting ring, a control ring, a drive bar, and an expansion bar. The connecting ring has several connecting grooves on its outer side, and the connecting grooves are arranged in a circular array on the outer side of the connecting ring. Several expansion bars are provided, and the bottom of each expansion bar is movably connected to the inside of the connecting groove via a rotating shaft. Several drive bars are provided, and one end of each drive bar is movably connected to the inside of the expansion bar via a rotating shaft. The end of each drive bar away from the expansion bar is movably connected to the outside of the control ring via a rotating shaft.

[0009] As described above, the connecting ring is located directly above the drill bit, and the connecting ring is movably connected to the bottom outer side of the main rod via a bearing. The outer side of the expansion bar is triangularly arranged to facilitate breaking the soil during expansion.

[0010] As mentioned above, the control ring is movably connected to the outside of the main rod via a thread, and the control ring is located in the middle position between the two sets of folding protective covers and the return spring.

[0011] As described above, the top of one set of the folding protective cover and the return spring abuts against the bottom of the control handle, and the bottom of the return spring abuts against the top surface of the control ring; the top of the other set of the folding protective cover and the return spring abuts against the bottom of the control ring, and the bottom of the return spring abuts against the top surface of the connecting ring.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: This invention uses a rotating control handle to rotate the main rod, which in turn drives the control ring downwards, pushing the drive bar to expand the expansion bar outwards. This effectively breaks up and expands the surrounding soil, significantly improving the ground anchor's grip and enhancing the stability of the photovoltaic array in strong winds. Simultaneously, the linkage design of the folding protective cover and the return spring always covers the outside of the main rod, preventing direct contact with soil that could cause wear or blockage. This not only extends the device's lifespan but also ensures smooth and safe operation, thus achieving a highly efficient and stable windproof fixing effect.

[0013] This invention provides a solid support foundation for the photovoltaic array through the synergistic effect of the ground anchor and the expansion bar, effectively resisting strong winds. Furthermore, the overall structure is compact, easy to operate, and the installation process is efficient and highly adaptable, making it suitable for different geological conditions and providing a reliable guarantee for the long-term safe operation of the photovoltaic power generation system.

[0016] In the description of this utility model, it should be understood that the terms "length," "width," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. The various embodiments of this utility model are described in detail below with reference to the accompanying drawings.

[0017] Please see Figures 1 to 4 The present invention preferably provides the following technical solution: a photovoltaic array windproof ground anchor fixing device, comprising: a top block 1 and a fixing hook 2, the bottom of the fixing hook 2 being fixedly connected to the middle position of the top of the top block 1, and the fixing hook 2 being used for fixing the photovoltaic array steel cable; the top block 1 being movably connected to a connecting operating mechanism 3 via a bearing; the outer side of the connecting operating mechanism 3 being movably connected to a windproof reinforcing mechanism 4; and the connecting operating mechanism 3 being fixedly connected to a drill bit 5, the bottom of which is conical.

[0018] Please see Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the connecting operating mechanism 3 includes a main rod 301, a control handle 302, a folding protective cover 303, and a return spring 304. The control handle 302 is fixedly connected to the outside of the main rod 301, and a thread is provided in the middle of the surface of the main rod 301. There are two sets of folding protective covers 303 and return springs 304. The folding protective covers 303 are respectively sleeved on the outside of the return springs 304, and the return springs 304 are respectively sleeved on the outside of the main rod 301. The top and bottom of the two sets of return springs 304 and folding protective covers 303 are fixedly connected. The top of the main rod 301 is movably connected to the bottom of the top block 1 through a bearing, and the bottom of the main rod 301 is fixedly connected to the middle of the top of the drill bit 5.

[0019] The drill bit 5 is screwed in and fixed by the rotational engagement of the thread on the surface of the main rod 301 and the control handle 302. At the same time, the elastic telescopic structure of the two sets of folding protective covers 303 and the return spring 304 forms a dynamic protective layer on the outside of the main rod 301. This not only prevents soil from directly contacting the main rod 301 and causing wear or blockage, but also ensures the stability of the operation process through the buffering effect of the return spring 304, thereby improving the durability and installation efficiency of the device.

[0020] Please see Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the windproof reinforcement mechanism 4 includes a connecting ring 401, a control ring 402, a drive bar 403, and an expansion bar 404. Several connecting grooves are formed on the outer side of the connecting ring 401, arranged in a circular array. Several expansion bars 404 are provided, and their bottoms are movably connected to the inside of the connecting grooves via rotating shafts. Several drive bars 403 are provided, with one end of each drive bar 403 movably connected to the inner side of the expansion bar 404 via rotating shafts. The ends of the drive bars 403 away from the expansion bar 404 are movably connected to the outer side of the control ring 402 via rotating shafts. The connecting ring 401 is located directly above the drill bit 5, and the connecting ring 401... The expansion bar 404 is movably connected to the bottom outer side of the main rod 301 via a bearing. The outer side of the expansion bar 404 is triangularly arranged to facilitate breaking the soil during expansion. The control ring 402 is movably connected to the outer side of the main rod 301 via a thread. The control ring 402 is located in the middle of the two sets of folding protective covers 303 and the return spring 304. The top of one set of folding protective covers 303 and the return spring 304 abuts against the bottom of the control handle 302, and the bottom of the return spring 304 abuts against the top surface of the control ring 402. The top of the other set of folding protective covers 303 and the return spring 304 abuts against the bottom of the control ring 402, and the bottom of the return spring 304 abuts against the top surface of the connecting ring 401.

[0021] The expansion and fixation of the soil are achieved through the coordinated work of the connecting ring 401, control ring 402, drive bar 403, and expansion bar 404. The connecting groove on the connecting ring 401 allows the expansion bar 404 to be connected movably via a rotating shaft. The drive bar 403 converts the movement of the control ring 402 into the outward unfolding action of the expansion bar 404, thereby effectively breaking and expanding the surrounding soil and enhancing the grip of the ground anchor. The threaded connection design of the control ring 402 allows it to slide along the axial direction of the main rod 301, while driving the extension and retraction of the folding protective cover 303 and the return spring 304. This ensures that the main rod 301 is always protected during the entire operation, avoiding direct contact with the soil, thereby improving the windproof stability and fixing effect of the ground anchor. The protection mechanism of the folding protective cover 303 and the return spring 304 also enhances the durability and ease of operation of the device.

[0022] Working principle: During use, the drill bit 5 is pressed into the installation ground using the main rod 301. Rotating the control handle 302 drives the main rod 301 to rotate, and the threaded drive control ring 402 on the surface of the main rod 301 slides downward along its axis. As the control ring 402 moves downward, it pushes the drive bar 403 downward. The bottom end of the drive bar 403 then pushes the expansion bar 404 outward, causing it to rotate around the bottom pivot and unfold outward, thereby expanding the surrounding soil. During the downward movement of the control ring 402, the folding protective cover 303 and the return spring 304 located above it elastically extend, while the folding protective cover 303 and the return spring 304 located below it are compressed and contract. Through this linkage structure, the two sets of folding protective covers 303 and return springs 304 always cover the outside of the main rod 301, forming effective protection and preventing direct contact between the soil and the main rod 301. Finally, the fixing cable of the photovoltaic array is connected to the fixing hook 2 to complete the installation.

[0023] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part. Among these, there are various ways to install detachably, such as by using a combination of plug-in and snap-fit, or by using bolts for connection, etc.

[0024] In addition, all the connections / connections mentioned in the article do not refer to direct connection of components, but rather to the formation of a better connection structure by adding or removing connecting accessories according to the specific implementation situation.

[0025] The above description of the specific embodiments of this utility model is only used to further illustrate this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-essential improvements and adjustments made to this utility model by technical engineers based on the above description of the utility model shall fall within the scope of protection of this utility model.
