Description

Technical Field

[0001] The present invention belongs to the technical field of stay cable anchoring, and relates to a flexible stay cable anchoring device for a photovoltaic tea garden. Background Art

[0002] The flexible stay cable anchoring device is increasingly widely used in photovoltaic tea gardens. With the large-scale construction of photovoltaic tea gardens, the photovoltaic brackets require an anchoring method with good terrain adaptability to ensure their stability and durability. In traditional fields such as bridges and buildings, rigid anchoring schemes are usually adopted for stay cable anchoring devices. However, due to the variable installation environment of photovoltaic tea gardens and the large vibration amplitude of stay cables, the traditional anchoring methods show certain defects in long-term applications and are difficult to effectively adapt to the terrain characteristics of tea gardens and the continuously changing environmental impacts.

[0003] Existing stay cable anchoring devices, such as the flexible stay cable anchoring devices for landscape decoration of some bridges, usually include components such as anchoring sleeves, bearing plates, and helical springs. These designs can, to a certain extent, adapt to the deformation caused by the vibration of the brackets and provide appropriate tension to the stay cables to relieve the fatigue caused by uneven stress on the cables. However, in the application scenario of photovoltaic tea gardens, due to the large and frequent continuous vibration of the photovoltaic bracket structure, especially under wind loads, temperature changes, and uneven tea garden soil, the helical springs of traditional devices are prone to fatigue due to long-term compression, resulting in a decrease in their elasticity and an inability to provide sufficient stability, affecting the reliability of the entire anchoring system.

[0004] In addition, most current anchoring devices have limitations in terms of adjustment. Traditional adjustment devices mostly achieve adjustment based on threaded connections. In the specific scenario of photovoltaic tea gardens, frequent adjustment operations will lead to increased wear of the threaded parts, thereby reducing the accuracy and stability of the system. Coupled with the lack of effective limit design, the adjustment nuts are prone to self-rotation during long-term vibration, resulting in anchoring loosening, thereby increasing the maintenance cost.

[0005] Therefore, in the field of flexible stay cable bracket anchoring for photovoltaic tea gardens, there is an urgent need for a new type of anchoring device that can effectively cope with complex terrain environments, improve adjustment accuracy, prevent self-rotation, and reduce spring fatigue, so as to achieve higher stability, extend the service life of equipment, and reduce maintenance requirements. Such a device should be able to effectively protect the anchoring components and maintain adaptability to vibration during long-term operation, making it more suitable for scenarios where flexible brackets work outdoors for a long time in photovoltaic tea gardens. Summary of the Invention

[0006] The purpose of the present invention is to provide a flexible stay cable anchoring device for a photovoltaic tea garden to solve the problems of equipment instability caused by spring fatigue, inconvenient adjustment, and anchoring loosening of traditional anchoring devices in a long-term vibration environment.

[0007] The object of the present invention can be achieved by the following technical solutions:

[0008] A flexible cable-stayed anchoring device for a photovoltaic tea garden, comprising:

[0009] A steel seat;

[0010] A fixed sleeve obliquely fixed on the steel seat;

[0011] And a flexible anchoring mechanism, which includes an installation cylinder fixedly installed in the fixed sleeve, an adjustment cylinder located in the installation cylinder and capable of axially moving along the installation cylinder to adjust its position, a sliding plate slidably arranged inside the adjustment cylinder, and a first spring with two ends respectively abutting against the sliding plate and the top of the adjustment cylinder. The to-be-anchored end of the cable-stayed cable penetrates into the adjustment cylinder and is fixed to the sliding plate, and the first spring is kept in a compressed state.

[0012] Furthermore, an adjustment nut is rotatably arranged on the installation cylinder, and the adjustment nut is threadedly connected to the outer side of the bottom of the adjustment cylinder. By rotating the adjustment nut, the adjustment cylinder axially moves in the installation cylinder.

[0013] Furthermore, the bottom of the installation cylinder is provided with an annular protrusion protruding outward, the adjustment nut is rotatably sleeved on the annular protrusion, and the installation cylinder is also provided with a limit ring capable of axially sliding along it. A plurality of card slots are circumferentially arranged on one side surface of the adjustment nut facing the limit ring, and a clamping rod capable of being clamped into the card slots is processed on the limit ring.

[0014] More preferably, a second spring in a compressed state is further arranged between the side surface of the limit ring far from the adjustment nut and the installation cylinder.

[0015] Furthermore, a limit slider is also installed on the outer side surface of the adjustment cylinder near the top end, and a limit sliding groove slidably matched with the limit slider is axially arranged inside the installation cylinder.

[0016] Furthermore, a sealing gasket is also arranged between the top end of the adjustment cylinder and the installation cylinder.

[0017] Furthermore, a first sealing rubber ring is also arranged at the through hole on the installation cylinder for the cable-stayed cable to penetrate into.

[0018] Furthermore, a second sealing rubber ring is also arranged at the position near the bottom end on the inner side of the installation cylinder.

[0019] Furthermore, the fixed sleeve is divided into an upper sleeve and a lower sleeve which are spliced with each other. The middle area of the top cover of the upper sleeve is hollowed out, and the top area of the installation cylinder is allowed to protrude outward. The lower sleeve is fixedly connected to the steel seat.

[0020] Furthermore, one or more hollow grooves exposing the bottom area of the mounting cylinder are axially machined in the lower area of the fixed sleeve.

[0021] Compared with the prior art, the present invention has the following advantages:

[0022] (1) By adjusting the adjusting nut to adjust the adjusting cylinder, the adjusting cylinder moves downward along the direction of the stay cable, so that the adjusting cylinder and the sliding plate squeeze the spring, thereby restoring the elastic force of the spring, avoiding affecting the stay cable, facilitating the improvement of the service life of the device, and having high practicability;

[0023] (2) The limiting ring can drive the clamping rod to move under the elastic force of the second spring and clamp the clamping rod inside the corresponding clamping groove, facilitating the limiting of the adjusting nut and preventing the adjusting nut from rotating, thereby improving the stability of the device;

[0024] (3) By compressing the first spring through the sliding plate, the stay cable can be stretched and deformed along with the vibration of the flexible support of the photovoltaic tea garden, preventing the stay cable from flexing and deforming and affecting its use.

This embodiment is implemented on the premise of the technical solution of the present invention, and the detailed implementation manner and specific operation process are given, but the protection scope of the present invention is not limited to the following embodiments.

[0032] In the description of the present invention, it should be noted that the orientation or positional relationship indicated by the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present invention. In addition, the terms "first", "second", "third" are only used for descriptive purposes and should not be construed as indicating or implying relative importance.

[0033] In the description of the present invention, it should be noted that unless otherwise clearly specified and defined, the terms "installation", "connection", "coupling" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0034] In the following embodiments or examples, if there is no special description of the functional components or structures, it means that they are all conventional components or conventional structures adopted by those skilled in the art to achieve the corresponding functions.

[0035] To solve the problems in the prior art such as spring fatigue, anchoring loosening, and insufficient adjustment accuracy, the present invention provides a flexible anchoring device for a stay cable 4 in a photovoltaic tea garden. Refer to Figure 1 etc. as shown, including:

[0036] A steel seat 1;

[0037] A fixed sleeve 2 inclined and fixed on the steel seat 1;

[0038] And a flexible anchoring mechanism 3, which includes an installation cylinder 5 fixedly installed in the fixed sleeve 2, an adjustment cylinder 6 located inside the installation cylinder 5 and capable of axially moving along the installation cylinder 5 to adjust its position, a sliding plate 7 slidably disposed inside the adjustment cylinder 6, and a first spring 8 with both ends respectively abutting against the sliding plate 7 and the top of the adjustment cylinder 6. The end of the stay cable 4 to be anchored penetrates into the inside of the adjustment cylinder 6 and is fixed to the sliding plate 7, and the first spring 8 is kept in a compressed state.

[0039] In some specific embodiments, please refer to Figure 2 and Figure 3As shown in the figure, a regulating nut 9 is rotatably provided on the mounting cylinder 5. The regulating nut 9 is threadedly connected to the outer side of the bottom of the regulating cylinder 6. By rotating the regulating nut 9, the regulating cylinder 6 moves axially within the mounting cylinder 5. Here, only a degree of freedom of relative rotation is maintained between the regulating nut 9 and the mounting cylinder 5, and they are relatively fixed axially.

[0040] In a more specific embodiment, a ring-shaped protrusion protruding outward is provided at the bottom of the mounting cylinder 5. The regulating nut 9 is rotatably sleeved on the ring-shaped protrusion. A limiting ring 10 capable of sliding axially is further provided on the outer side of the mounting cylinder 5. A plurality of card slots are arranged circumferentially on the surface of the regulating nut 9 facing the limiting ring 10, and a clamping rod capable of being clamped into the card slots is machined on the limiting ring 10. In the normal state, the card slots in the limiting ring 10 are pressed into the card slots of the regulating nut 9, so that the regulating nut 9 is limited and cannot rotate. When it is necessary to rotate the regulating nut 9, the limiting ring 10 is lifted upward, so that the clamping rod is disengaged from the card slot, thereby restoring the rotational freedom of the regulating nut 9. In this way, by rotating the regulating nut 9 and based on the threaded engagement relationship between the regulating nut 9 and the regulating cylinder 6, the regulating cylinder 6 moves up and down correspondingly, thereby adjusting the compression degree of the spring. In addition, the number of the card slots can be provided with a plurality of them equidistantly in the circumferential direction. The more the number distribution is, the better the adjustment accuracy of the regulating nut 9 is. At the same time, the number of the clamping rods does not need to be the same as the number of the card slots. Generally, two can be symmetrically arranged. If the strength is sufficient, one can also be set, or more can be set.

[0041] In a more preferred embodiment, a second spring 13 in a compressed state is further provided between the surface of the limiting ring 10 away from the regulating nut 9 and the mounting cylinder 5. Through the elastic force exerted by the second spring 13, the clamping rod of the limiting ring 10 can maintain the limiting effect on the regulating nut 9.

[0042] In some specific embodiments, please refer to Figure 4 As shown in the figure, a limiting slider 14 is further installed on the outer surface of the regulating cylinder 6 near the top end. A limiting chute slidably matched with the limiting slider 14 is axially provided inside the mounting cylinder 5. Here, through the cooperation of the limiting slider 14 and the limiting chute, the regulating cylinder 6 inside the mounting cylinder 5 can only move back and forth within a limited axial stroke, preventing it from rotating.

[0043] In some specific embodiments, please refer to Figure 2As shown in the figure, a sealing gasket 12 is further provided between the top end of the adjusting cylinder 6 and the mounting cylinder 5. Here, the sealing gasket is preferably made of a rubber material with high compression recovery and wear resistance, which can ensure its sealing performance to the greatest extent. In this way, when the adjusting cylinder 6 moves downward, since the movement of the adjusting cylinder 6 will not be too large, the sealing gasket 12 may still be in contact with the adjusting cylinder 6. At the same time, the sealing gasket 12 plays an auxiliary sealing role in this process. When the adjusting cylinder moves downward too much and loses contact with the sealing gasket, the dust-proof performance will be reduced.

[0044] In some specific embodiments, please refer to Figure 2 As shown in the figure, a first sealing rubber ring 11 is further provided at the through hole on the mounting cylinder 5 for the stay cable 4 to extend into.

[0045] In some specific embodiments, please refer to Figure 3 As shown in the figure, a second sealing rubber ring 15 is further provided at a position near the bottom end inside the mounting cylinder 5.

[0046] In some specific embodiments, the fixed sleeve 2 is divided into an upper sleeve and a lower sleeve that are spliced together. The middle area of the top cover of the upper sleeve is hollowed out, and the top area of the mounting cylinder 5 is allowed to extend outwards. The lower sleeve is fixedly connected to the steel seat 1. The setting method of the fixed sleeve 2 here can facilitate the installation of internal structures such as the mounting cylinder 5. At the same time, the upper sleeve and the lower sleeve can be installed and fixed by conventional connection methods in the art.

[0047] In some specific embodiments, one or more hollow grooves are axially machined in the lower region of the fixed sleeve 2 to expose the bottom region of the mounting cylinder 5. Through the setting of the hollow grooves, it is convenient for subsequent use and adjustment of components such as the adjusting nut 9 and the limit ring 10.

[0048] The above embodiments can be implemented separately, or any two or more of them can be combined for implementation.

[0049] The above embodiments will be described in more detail below with specific examples.

[0050] Example 1:

[0051] Please refer to Figures 1 to 4, this embodiment provides a flexible cable-stayed cable anchoring device, which includes a steel seat 1. One side of the top end of the steel seat 1 is inclined and fixedly provided with a fixed sleeve 2. An anchoring mechanism 3 is installed inside the fixed sleeve 2. The anchoring mechanism 3 includes an installation cylinder 5. Inside the installation cylinder 5, an adjustment cylinder 6 is screwed and installed through an adjustment nut 9. A sliding plate 7 is slidably arranged inside the adjustment cylinder 6. One end of the sliding plate 7 is fixedly provided with a cable-stayed cable 4. A first spring 8 is fixedly installed between one end of the sliding plate 7 and the inner wall of the adjustment cylinder 6. The cable-stayed cable 4 passes through the adjustment cylinder 6 and is slidably arranged inside the installation cylinder 5. A limiting mechanism is arranged on one side of the adjustment nut 9 corresponding to the outside of the installation cylinder 5. The adjustment nut 9 can adjust the adjustment cylinder 6, so that the adjustment cylinder 6 moves inside the installation cylinder 5, which is convenient for subsequently squeezing the first spring 8, thereby resetting the elastic force of the first spring 8, improving the service life of the device, and having high practicability.

[0052] In this embodiment, limiting sliders 14 are symmetrically arranged at the top and bottom of one end of the adjustment cylinder 6. The limiting sliders 14 are installed in a limiting and sliding manner inside the inner wall of the installation cylinder 5. The first spring 8 is sleeved on the outside of one end of the cable-stayed cable 4. A sealing gasket 12 is fixedly arranged inside the installation cylinder 5 corresponding to the outside of the cable-stayed cable 4. A first sealing rubber ring 11 is fixedly arranged inside one end of the installation cylinder 5. The cable-stayed cable 4 is installed inside the first sealing rubber ring 11. By setting the limiting sliders 14, the adjustment cylinder 6 can be limited, which is convenient for the adjustment cylinder 6 to move inside the installation cylinder 5 rather than rotate. The movement of the adjustment cylinder 6 can squeeze the first spring 8 through the sliding plate 7, which is convenient for restoring the elastic force of the first spring 8. By setting the first sealing rubber ring 11 and the sealing gasket 12, the sealing performance of the device can be improved, and the waterproof and dustproof performance of the device can be improved.

[0053] In this embodiment, the adjustment nut 9 is installed in a limiting and rotating manner on the outside of the other end of the installation cylinder 5. The adjustment nut 9 is screwed and installed on the outside of one end of the adjustment cylinder 6. The limiting mechanism includes a limiting ring 10. The limiting ring 10 is slidably arranged on the installation cylinder 5 corresponding to one side of the adjustment nut 9. A card slot is circularly opened inside the side wall of the adjustment nut 9. On one side of the limiting ring 10, clamping rods are symmetrically and fixedly arranged at the top and bottom. The clamping rods are clamped and installed inside the card slot. A second spring 13 is fixedly arranged between the other side of the limiting ring 10 and the installation cylinder 5. The outside of the installation cylinder 5 is provided with threads. The installation cylinder 5 is screwed and installed inside the fixed sleeve 2. The limiting ring 10 can move towards the direction of the adjustment nut 9 under the elastic force of the second spring 13 and fit and contact with each other, so that the clamping rods can be inserted into the corresponding slots, thereby improving the stability of the adjustment nut 9 and preventing the adjustment nut 9 from rotating self.

[0054] When using this flexible anchoring device for stay cables, the steel seat 1 is fixed to the ground. The installation cylinder 5 is screwed and installed inside the fixed sleeve 2. One end of the stay cable 4 passes through the installation cylinder 5 and the adjusting cylinder 6 and is fixedly connected to the sliding plate 7. By compressing the first spring 8 through the sliding plate 7, the stay cable 4 can be stretched and deformed along with the vibration of the flexible support, preventing the flexural deformation of the stay cable 4 from affecting its use. After long-term use, when the elastic force of the first spring 8 weakens, slide the limit ring 10 in the reverse direction away from the adjusting nut 9. The limit ring 10 drives the clamping rod to move out of the internal of the clamping groove and compresses the second spring 13. Rotate the adjusting nut 9. The adjusting nut 9 is screwed to drive the adjusting cylinder 6 to rotate. The adjusting cylinder 6 can be limited by the limit slider 14, so that the adjusting cylinder 6 moves downward along the direction of the stay cable 4, making the adjusting cylinder 6 and the sliding plate 7 squeeze the first spring 8, thereby restoring the elastic force of the first spring 8 and avoiding affecting the stay cable 4, with high practicability. After the adjustment is completed, loosen the limit ring 10. The limit ring 10 slides in the reverse direction under the elastic force of the second spring 13 and clamps the clamping rod inside the corresponding clamping groove, facilitating the limitation of the adjusting nut 9 and preventing the adjusting nut 9 from rotating self, thereby improving the stability of the device.

[0055] The above description of the embodiments is to enable those of ordinary skill in the art to understand and use the invention. It is obvious that those skilled in the art can easily make various modifications to these embodiments and apply the general principles described herein to other embodiments without creative efforts. Therefore, the present invention is not limited to the above embodiments, and the improvements and modifications made by those skilled in the art without departing from the scope of the present invention according to the disclosure of the present invention should be within the protection scope of the present invention.
