Description

Technical Field

[0001] This utility model relates to the field of photovoltaic protection technology, and in particular to a protective railing installation device for photovoltaic power generation equipment. Background Technology

[0002] As a core facility ensuring the safe operation of photovoltaic power stations, protective fences serve multiple important functions: isolating dangerous electrified areas to prevent accidental entry by personnel, effectively blocking wildlife intrusion, and providing anti-theft protection for the equipment. Traditional protective fence systems mainly consist of mounting posts and protective netting. The mounting posts are fixed to the ground by a base plate, requiring specialized fencing installation equipment during construction. This equipment typically employs an openable ring structure design. Installation requires precise positioning on the ground, placement of the device, and then filling the base plate with cement mortar. After the mortar hardens, the device is removed.

[0003] Existing fencing installation devices generally employ a structure consisting of two semi-circular plates, opened and closed via a hinged connection at one end and a horizontal bolt connection at the other. However, this method has significant drawbacks in actual construction: the horizontally positioned bolts are inconvenient to operate when opening and closing. Furthermore, because the device needs to be buried underground, construction workers must spend a considerable amount of time clearing the sand and soil inside the device to ensure that the cement mortar can fully infiltrate the ground to form a stable foundation. This excavation operation is not only inefficient but also easily leads to worker fatigue when working in confined spaces. Utility Model Content

[0019] The four supporting feet are evenly spaced along the central axis;

[0020] Four connecting bars, the four connecting bars connecting to the four supporting feet;

[0021] A center gasket, located in the middle of the four abutment feet, is used to connect the connecting strip and the abutment feet;

[0038] Please see Figures 1 to 3 This utility model provides a protective railing installation device 1000 for photovoltaic power generation equipment, comprising:

[0039] First arc plate 1;

[0040] The second arc plate 2 has one end rotatably connected to one end of the first arc plate 1. The other end of the first arc plate 1 is provided with a first protrusion 12, and the other end of the second arc plate 2 is provided with a second protrusion 22. The first protrusion 12 is located above the second protrusion 22, and both the first protrusion 12 and the second protrusion 22 have threaded holes.

[0041] The first screw 3 is vertically arranged and threadedly connected to the first protrusion 12 and the second protrusion 22 to lock the first arc plate 1 and the second arc plate 2.

[0042] The third arc plate 4 and the second arc plate 2 have a recessed mounting position on their tops. The third arc plate 4 is installed in the mounting position. The tops of the third arc plate 4 and the first arc plate 1 are flush. The third arc plate 4 and the second arc plate 2 are detachably connected. When the device is inserted into the ground, the third arc plate 4 can be opened so that the sand inside can be easily dug out from the mounting position.

[0043] The rotatable connection between the first arc-shaped plate 1 and the second arc-shaped plate 2 can be achieved using a hinge structure or a pivot structure. The threaded holes of the first protrusion 12 and the second protrusion 22 can be through holes or blind holes, and the thread specification can be selected according to actual needs. The first screw 3 can be a standard threaded rod or a custom threaded rod, and its length should ensure that it can completely pass through the threaded holes of the first protrusion 12 and the second protrusion 22. The shape of the mounting position can match the third arc-shaped plate 4 to form a stable mounting structure. The detachable connection of the third arc-shaped plate 4 can be achieved using a snap-fit ​​structure or a bolt connection, facilitating quick opening and closing.

[0044] This technical solution solves the problem of cumbersome excavation of internal sand during construction by incorporating an openable arc-shaped plate structure. Once the device is inserted into the ground, the third arc-shaped plate 4 can be opened, allowing sand to be excavated directly from the installation location, simplifying the construction process. The vertical positioning of the first screw 3 provides stable locking force and improves operational convenience, ensuring the structural strength of the device during use. Compared to existing technologies, this device not only maintains the original installation function but also incorporates a structural design that facilitates the removal of internal sand, thus improving construction efficiency.

[0045] Furthermore, one end of the third arc plate 4 is rotatably connected to one end of the mounting position, the other end of the third arc plate 4 is provided with a third protrusion 41, and the other end of the mounting position is provided with a fourth protrusion 23. The fourth protrusion 23 is located above the third protrusion 41. Both the third protrusion 41 and the fourth protrusion 23 have threaded holes, and a second screw 5 is provided in the threaded holes.

[0046] Specifically, the third arc-shaped plate 4 achieves its opening and closing function with the mounting position through a rotating connection, which can be a hinge structure or a pivot structure. The third protrusion 41 and the fourth protrusion 23 are made of metal, with through-hole threaded holes. The second screw 5 is a standard threaded rod, which can be tightened or loosened by rotation. In a preferred embodiment, the third protrusion 41 is fixed to the third arc-shaped plate 4 by welding, and the fourth protrusion 23 is integrally formed with the mounting position. Lubricating grease can be applied to the rotating connection to reduce friction loss.

[0047] Therefore, this technical solution, by setting up an openable third arc-shaped plate 4 structure, allows the third arc-shaped plate 4 to be opened when the device is inserted into the ground, making it easier for construction personnel to clean the internal sand and soil from the installation position.

[0048] Furthermore, one end of the first arc plate 1 is provided with a protruding first fixing block 11, and one end of the second arc plate 2 is provided with a protruding first rotating block 24. The first fixing block 11 and the first rotating block 24 are rotatably connected.

[0049] Specifically, the first fixed block 11 and the first rotating block 24 are rotatably connected by a rotating shaft. The first fixed block 11 can be welded or bolted to the end of the first arc-shaped plate 1, and the first rotating block 24 is fixed to the end of the second arc-shaped plate 2 in the same way. The rotating shaft can be made of stainless steel, with a diameter in the range of 8-12mm, and both ends are fixed with nuts to prevent it from falling off. As a preferred embodiment, wear-resistant gaskets can be provided on the contact surfaces of the first fixed block 11 and the first rotating block 24 to reduce frictional loss. In addition, the thickness of the first fixed block 11 and the first rotating block 24 is preferably 10-15mm to ensure connection strength.

[0050] Therefore, this technical solution achieves a reliable rotatable connection between the two arc-shaped plates by setting a fixed block and a rotating block at the connection end of the first arc-shaped plate 1 and the second arc-shaped plate 2, respectively. Compared with the simple hinge connection in the prior art, this protruding connection structure has higher mechanical strength and can withstand the impact force during construction. At the same time, the setting of the fixed block and rotating block makes it less likely for mud and sand to accumulate at the connection point, facilitating maintenance. This design solves the problem of easy damage to the connection part of traditional fence installation devices, improving the service life and reliability of the device.

[0051] Furthermore, one end of the mounting position is provided with a protruding second fixing block 21, and one end of the third arc plate 4 is provided with a protruding second rotating block 42, and the second fixing block 21 and the second rotating block 42 are rotatably connected.

[0052] Specifically, the second fixing block 21 is integrally formed and fixedly connected to the mounting position, while the second rotating block 42 is welded to the third arc-shaped plate 4. The second fixing block 21 and the second rotating block 42 are rotatably connected by a pin, which is made of stainless steel to prevent corrosion. In a preferred embodiment, the contact surfaces of the second fixing block 21 and the second rotating block 42 are provided with a lubricating coating to reduce frictional resistance. Thus, the third arc-shaped plate 4 can rotate and open / close around the pin from 0 to 180 degrees.

[0053] To address this, this solution employs a rotating connection structure, enabling the third arc-shaped plate 4 to open and close quickly. Once the device is inserted into the ground, construction workers can open the third arc-shaped plate 4 with just one hand, facilitating the removal of internal sand and soil from the installation location. Compared to existing technologies that require complete disassembly of the arc-shaped plate, this design significantly improves construction efficiency while avoiding the risk of lost parts. Specifically, the rotating connection structure adopts a modular design, allowing for individual replacement and maintenance of each component, thus reducing operating costs.

[0054] Furthermore, the inner wall surface of the first arc-shaped plate 1 is provided with graduations.

[0055] Specifically, the graduations can be formed on the inner wall of the first arc-shaped plate 1 using methods such as laser engraving, mechanical stamping, or chemical etching. As a preferred embodiment, the graduations are marked in centimeters, with a minimum graduation interval of 1 centimeter. The graduation lines can be configured as a groove structure, filled with fluorescent material to improve nighttime visibility. Furthermore, the graduation direction can be set perpendicular to the axis of the first arc-shaped plate 1, facilitating direct reading of the insertion depth by construction personnel. In addition, the graduation area can cover a range of at least 50 centimeters extending downwards from the top of the first arc-shaped plate 1 to meet the measurement needs of different installation depths.

[0056] Therefore, by setting graduations on the inner wall of the curved plate, construction workers can intuitively and accurately determine the depth to which the device is inserted into the ground, ensuring that the burial depth of the guardrail installation posts meets design requirements. This technical solution solves the problem of requiring additional measuring tools in traditional installation processes, simplifies the construction process, and improves installation efficiency.

[0057] Furthermore, the protective railing installation device 1000 for photovoltaic power generation equipment also includes a support structure 6, which is located above the first arc plate 1 and the third arc plate 4. When construction workers use tools to drive the device into the ground, they apply force toward the support structure 6 to ensure that other parts are not damaged.

[0058] The support structure 6 includes a rotating part and a main body. The rotating part is rotatably mounted on the side wall of the first arc-shaped plate 1, and the main body is connected to the rotating part. The main body is provided with multiple supporting feet 63, which abut against the tops of the first arc-shaped plate 1 and the third arc-shaped plate 4, respectively. The rotating part is used to rotate and open the main body to ensure that the installation post of the guardrail can be inserted. The main body includes four supporting feet 63, which are evenly spaced along the central axis. Four connecting strips 64 connect the four supporting feet 63. A central washer 65 is located in the middle of the four supporting feet 63 and is used to connect the connecting strips 64 and the supporting feet 63. Construction workers apply downward force to the four supporting feet 63 and the central washer 65 according to the actual situation to press the bottom of the device into the ground. The rotating part includes a rotating shaft 61 and a connecting block 62. The rotating shaft 61 is fixedly mounted on the outside of the first arc-shaped plate 1. The connecting block 62 has a through hole, which fits onto the rotating shaft 61, and the connecting block 62 is connected to the main body. The through hole is elliptical to create a gap between the rotating shaft 61 and the hole wall, providing a longitudinal buffer space between the main body and the rotating part when force is applied. An elastic pad is provided at the bottom of the supporting foot 63.

[0059] Specifically, the support structure 6 uses a rotating part to open and close the main body, while the main body uses the supporting feet 63 to evenly distribute the impact force during construction. The central gasket 65 and connecting strip 64 enhance the structural stability of the main body. The elliptical through-hole design provides longitudinal buffer space to avoid structural damage caused by rigid impacts. The elastic gasket effectively absorbs impact vibrations and protects the surface of the curved plate from damage. Thus, this structure significantly reduces the risk of mechanical damage to the device body during installation while ensuring construction efficiency.

[0060] Furthermore, the support structure 6 includes:

[0061] A rotating part is rotatably disposed on the side wall of the first arc-shaped plate 1;

[0062] The main body is connected to the rotating part. The main body is provided with multiple supporting feet 63, which support the top of the first arc plate 1 and the third arc plate 4 respectively. The rotating part is used to rotate and open the main body to ensure that the installation post of the guardrail extends in.

[0063] Specifically, the main body includes four supporting feet 63, which are evenly spaced along the central axis. Four connecting strips 64 connect the four supporting feet 63, and a central gasket 65 is located in the middle of the four supporting feet 63, used to connect the connecting strips 64 and the supporting feet 63. Construction workers apply downward force to the four supporting feet 63 and the central gasket 65 according to the actual situation to press the bottom of the device into the ground. The rotating part includes a rotating shaft 61 and a connecting block 62. The rotating shaft 61 is fixedly mounted on the outside of the first arc-shaped plate 1. The connecting block 62 has a through hole that fits onto the rotating shaft 61 and connects to the main body. The through hole is elliptical, creating a gap between the rotating shaft 61 and the hole wall, providing longitudinal buffer space between the main body and the rotating part when force is applied. Elastic gaskets are provided at the bottom of the supporting feet 63.

[0064] Therefore, the support structure 6, by setting multiple supporting feet 63 and a central washer 65, can evenly distribute the impact force during construction, avoiding excessive local stress that could damage the device. The elliptical through-hole design of the rotating part provides longitudinal buffer space, further protecting the device from damage during construction. The elastic washer reduces friction between the supporting feet 63 and the curved plate, extending its service life. This technical solution effectively solves the problem of device damage during construction in existing technologies, improving construction efficiency and safety.

[0065] Furthermore, the main body includes:

[0066] Four supporting feet 63 are evenly spaced along the central axis;

[0067] Four connecting bars 64 connect to four supporting feet 63;

[0068] A center gasket 65 is located in the middle of the four abutment feet 63 and is used to connect the connecting strip 64 and the abutment feet 63.

[0069] The construction workers applied downward force to the four supporting feet 63 and the central pad 65 according to the actual situation, so as to press the bottom of the device into the ground.

[0070] Specifically, the supporting foot 63 is made of metal, with anti-slip textured bottom to increase friction. The connecting strip 64 is telescopic, its length adjustable via adjusting bolts to accommodate curved plates of different sizes. The center gasket 65 is made of rubber, providing cushioning and preventing damage to the curved plate during force application. In a preferred embodiment, the supporting foot 63 and the connecting strip 64 are hinged, allowing the supporting foot 63 to automatically adjust its contact angle according to the curvature of the curved plate surface.

[0071] Therefore, this technical solution achieves balanced force distribution through four evenly distributed support feet 63, avoiding structural deformation caused by localized stress concentration. The connecting strip 64 creates a stable frame structure for the main body, while the central pad 65 serves to transfer force and provide cushioning. Compared with existing technologies, this structure can more effectively and evenly transfer the downward pressure from construction workers to the bottom of the device, improving installation efficiency and reducing damage to the curved plate. Simultaneously, the adjustable connecting strip 64 and the hinged support feet 63 design enhance structural adaptability, enabling it to match the installation requirements of guardrails of different specifications.

[0072] Furthermore, the rotating part includes:

[0073] Rotating shaft 61 is fixedly disposed on the outer side of the first arc-shaped plate 1;

[0074] Connecting block 62 has a through hole that fits onto rotating shaft 61. Connecting block 62 connects to the main body. The through hole is an elliptical hole so that there is a gap between rotating shaft 61 and the hole wall, so that the main body has a longitudinal buffer space with the rotating part when force is applied.

[0075] Specifically, the rotating shaft 61 can be made of stainless steel with a diameter ranging from 10-15mm, and is fixed to the outside of the first arc-shaped plate 1 by welding. The through hole of the connecting block 62 is designed to be elliptical, with its major axis being 2-5mm larger than the diameter of the rotating shaft 61, and its minor axis having the same diameter as the rotating shaft 61. The connecting block 62 can be cast from cast iron with a thickness of 8-12mm. The main body is fixedly connected to the connecting block 62 by bolts. As a preferred embodiment, the major axis of the elliptical hole is aligned with the direction of force on the main body. When the main body is subjected to downward pressure, the connecting block 62 can undergo a slight displacement along the rotating shaft 61, creating a buffering effect.

[0076] Therefore, this technical solution, by setting an elliptical through-hole structure, enables the main body to generate longitudinal displacement buffer when subjected to force, effectively mitigating the impact force during construction. Compared with existing technologies, this structure can avoid component damage caused by rigid connections and extend the service life of the device. In specific implementation, the buffer space is controlled within the range of 3-8mm, which ensures the buffering effect without affecting the overall stability of the device. The gap between the connecting block 62 and the rotating shaft 61 can be filled with lubricating grease to reduce friction loss. This design is particularly suitable for construction scenarios that require frequent impact, protecting the rotating connection parts through the buffering effect.

[0077] Furthermore, the bottom of the supporting foot 63 is provided with an elastic pad 66.

[0078] The elastic pad 66 can be made of elastic materials such as rubber, silicone, or polyurethane, with a thickness ranging from 3 to 10 mm. In practice, the elastic pad 66 can be fixed to the bottom of the support foot 63 by adhesive bonding or snap-fit. As a preferred embodiment, the bottom surface of the elastic pad 66 can be provided with anti-slip texture to enhance the coefficient of friction. In another embodiment, the elastic pad 66 can adopt a multi-layer composite structure, including a base layer and a wear-resistant layer, wherein the base layer provides cushioning performance, and the wear-resistant layer is made of high-density polyethylene material. Furthermore, the edge of the elastic pad 66 can be designed with an upward-curved structure to completely cover the bottom edge of the support foot 63.

[0079] This technical solution effectively solves the problem of device damage caused by direct rigid contact during construction by setting an elastic pad 66 at the bottom of the supporting foot 63. When construction personnel apply impact force to the support structure 6, the elastic pad 66 can absorb part of the impact energy, preventing a hard collision between the supporting foot 63 and the top of the curved plate. At the same time, the deformation characteristics of the elastic pad 66 can make the force distribution more uniform and prevent local stress concentration. Compared with the prior art, this structure not only protects the device body from impact damage, but also reduces the operator fatigue through buffering, and improves the stability and reliability of the installation operation.

[0080] The above description is merely an exemplary embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
