Description

Technical Field

[0001] This utility model relates to the field of photovoltaic support technology, specifically to a prestressed suspension flexible support for photovoltaic systems used in highway service areas. Background Technology

[0002] Because traditional service area photovoltaic systems are limited by insufficient roof area and poor adaptability to complex environments, a special prestressed suspension flexible support system for photovoltaic systems in highway service areas has been established. This system has excellent adaptability and flexibility, and can easily cope with the complex and ever-changing installation environment of highway service areas. Therefore, it provides highway service areas with an efficient and reliable photovoltaic power generation solution, promoting the promotion and application of green energy.

[0003] Chinese patent CN218494095U discloses a cable-stayed flexible photovoltaic bracket that can extend the service life of photovoltaic panels and suspension cables. This utility model includes a cable-stayed support mechanism and support legs; the cable-stayed support mechanism includes support blocks and suspension cables, with the suspension cables threaded through the support blocks, which are multiple blocks arranged sequentially; there are at least two support legs arranged sequentially, with a support block fixedly mounted on the top of each support leg; the invention is characterized by further including a buffer mechanism, which is disposed between two adjacent support legs, with a support block mounted on its top; the buffer mechanism includes a buffer leg and a buffer rod; the buffer rod is elastically slidably mounted on the buffer leg and fixedly connected to the support block.

[0004] The aforementioned patent still has the following shortcomings: it has the defect of poor wind resistance. Since the existing device is usually composed of steel cables, its rigidity is weak. Under the action of strong wind, it is easy to cause excessive deformation in the middle of the span, which leads to the separation of the photovoltaic module clamping block from the steel cable, and even the phenomenon of photovoltaic back sheet tearing, which seriously affects the overall reliability of the photovoltaic power station. Utility Model Content

[0005] This utility model provides a photovoltaic prestressed suspension flexible support for highway service areas, which solves the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, the technical solution of this utility model is as follows:

[0007] An embodiment of this utility model provides a photovoltaic prestressed suspension cable flexible support for highway service areas, including a pole and further comprising:

[0008] A collapsing structure is installed at the bottom end of the upright. The collapsing structure includes a connecting seat rotatably connected to both sides of the upright, a hydraulic push rod installed on one side of the connecting seat, a fixing frame fixed at the bottom end of the upright, and a locking component installed inside the fixing frame.

[0009] The base is located at the bottom of the collapsed structure;

[0010] A lifting mechanism, located at the top of the upright, is used to adjust the height of the device;

[0011] A top frame is installed at the top of the lifting structure, and a fixing ring is fixed on one side of the top of the top frame;

[0012] A pre-tightening screw sleeve is installed on one side of the retaining ring, and a pre-tightening screw is connected to the internal thread on one side of the pre-tightening screw sleeve;

[0013] A steel cable is rotatably connected to one side of a pre-tightening screw, and a photovoltaic panel is installed at the top of each steel cable.

[0014] Through the above technical solution, the overall tilting or upright state of the upright pole can be switched by the tilting structure, the suspension height of the steel cable can be adjusted by the lifting structure, and the tension of the steel cable can be adjusted by rotating the pre-tightening screw and moving it into the pre-tightening sleeve to ensure that the photovoltaic panel maintains a stable posture.

[0015] Furthermore, the locking assembly includes a rotating seat rotatably connected to the outside of the fixed frame, buckles fixed to both sides of the top of the rotating seat, an electric telescopic rod fixed to one side of the fixed frame, a pusher installed at the telescopic end of the electric telescopic rod, a connecting rod rotatably connected to both sides of the pusher, and a pin rotatably connected to one side of the connecting rod and slidably connected to the fixed frame.

[0016] The above technical solution uses a hydraulic push rod to rotate the upright around the rotating seat, achieving tilting or uprighting. An electric telescopic rod then moves the push frame to insert the pin into the buckle plate, locking the position of the upright, improving the stability of the upright and reducing the load on the hydraulic push rod.

[0017] Furthermore, the pin extends through the fixing frame into the interior of the buckle plate, and the pin and the buckle plate form an insertion and removal structure.

[0018] The above technical solution uses pins inserted into the buckle plate to form a plug-in mechanical lock. The design of the pins being symmetrically distributed along the vertical center line makes the locking force evenly distributed, avoiding deformation or failure caused by stress concentration on one side.

[0019] Furthermore, the fixing frame and the upright form a welded integrated structure, and the pins are symmetrically distributed on the vertical center line of the fixing frame.

[0020] Through the above technical solution, the fixing frame and the upright are welded into a whole, which significantly improves the rigidity and bending strength of the connection node.

[0021] Furthermore, the lifting structure includes a drive motor installed inside one side of the upright, a bevel gear set installed at the end of the output shaft of the drive motor, a support sleeve fixed inside the bottom of the upright, a lead screw rotatably connected inside the support sleeve and connected to the bevel gear set, a movable sleeve threaded to the outside of the lead screw, an inner tube fixed to the outside of the movable sleeve and slidably connected to the upright, and a protective sleeve sleeved on the outside of the upright.

[0022] The above technical solution uses a drive motor to drive a lead screw to rotate via a bevel gear set, which in turn drives a moving sleeve to lift the inner tube, thereby achieving the adjustment of the top frame height.

[0023] Furthermore, the outer wall of the lead screw is provided with an external thread, and the inside of the movable sleeve is provided with an internal thread that cooperates with the external thread.

[0024] Through the above technical solution, the external thread of the lead screw and the internal thread of the moving sleeve cooperate with each other, realizing the precise movement of the moving sleeve when the lead screw rotates, thereby ensuring the stability and reliability of the lifting structure.

[0025] The above-described solution of this utility model has at least the following beneficial effects:

[0026] 1. This utility model uses a hydraulic push rod to push the upright pole to rotate around the rotating base, thereby achieving the tilting or uprighting action. An electric telescopic rod inserts a pin into the buckle plate to lock the position of the upright pole. This realizes the automatic tilting function of this device, reduces the impact of wind pressure on photovoltaic modules and brackets, prevents the brackets and modules from collapsing or breaking due to excessive wind force, and ensures the safe operation of the power station.

[0027] 2. This utility model uses a drive motor to drive a lead screw to rotate via a bevel gear set, which in turn drives a movable sleeve to lift the inner tube. This achieves the height adjustment function of the device, making it easy to adjust the height of the bracket under different terrain conditions to ensure that the photovoltaic modules remain horizontal, and also making the maintenance and cleaning of the photovoltaic modules more convenient.

Rather, these embodiments are provided so that this invention will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.

[0035] like Figures 1 to 4 As shown, an embodiment of this utility model provides a special photovoltaic prestressed suspension cable flexible support for highway service areas, including a pole 1, and further comprising:

[0036] The collapsing structure 2 is set at the bottom end of the upright 1. The collapsing structure 2 includes a connecting seat 203 rotatably connected to both sides of the upright 1, a hydraulic push rod 201 installed on one side of the connecting seat 203, a fixing frame 208 fixed at the bottom end of the upright 1, and a locking component set inside the fixing frame 208.

[0037] Base 3 is located at the bottom end of the collapsed structure 2;

[0038] The lifting structure 6 is located at the top of the upright 1 and is used to adjust the height of the device.

[0039] The top frame 7 is installed on the top of the lifting structure 6, and a fixing ring 10 is fixed on one side of the top of the top frame 7.

[0040] A preloaded screw sleeve 9 is installed on one side of the retaining ring 10, and a preloaded screw 8 is connected to the internal thread on one side of the preloaded screw sleeve 9;

[0041] The steel cable 5 is rotatably connected to one side of the pre-tightening screw 8, and a photovoltaic panel 4 is installed at the top of each steel cable 5.

[0042] In this embodiment of the utility model, the upright pole 1 serves as the main support body and is connected to the base 3 through the tilting structure 2, so as to realize the overall tilting or upright state switching of the upright pole 1. The lifting structure 6 drives the top frame 7 to lift and lower to adjust the suspension height of the steel cable 5. By rotating the pre-tightening screw 8 and moving it into the pre-tightening sleeve 9, the tension of the steel cable 5 can be adjusted to ensure that the photovoltaic panel 4 maintains a stable posture.

[0043] like Figures 2 to 3 As shown, the locking assembly includes a rotating seat 202 rotatably connected to the outside of the fixed frame 208, buckle plates 204 fixed to both sides of the top of the rotating seat 202, an electric telescopic rod 209 fixed to one side of the fixed frame 208, a pusher 206 installed at the telescopic end of the electric telescopic rod 209, a connecting rod 207 rotatably connected to both sides of the pusher 206, and a pin 205 rotatably connected to one side of the connecting rod 207 and slidably connected to the fixed frame 208.

The fixed frame 208 and the upright 1 form a welded integrated structure. The pins 205 are symmetrically distributed on the vertical center line of the fixed frame 208.

[0044] In this embodiment of the utility model, the hydraulic push rod 201 extends, causing it to push the upright 1 through the connecting seat 203, thereby driving the fixed frame 208 to rotate around the rotating seat 202, realizing the tilting or uprighting action. In the upright state, the electric telescopic rod 209 extends to push the push frame 206 to move, so that the push frame 206 inserts the pin 205 into the buckle plate 204 through the connecting rod 207, forming a mechanical lock, ensuring the rigid fixation of the upright 1, improving the stability of the upright 1 and reducing the load on the hydraulic push rod 201. During the tilting operation, the electric telescopic rod 209 retracts, causing the pin 205 to disengage from the buckle plate 204, releasing the lock to allow the upright 1 to tilt.

[0045] like Figure 4 As shown, the lifting structure 6 includes a drive motor 601 installed inside one side of the upright 1, a bevel gear set 607 installed at the end of the output shaft of the drive motor 601, a support sleeve 606 fixed inside the bottom of the upright 1, a lead screw 602 rotatably connected inside the support sleeve 606 and connected to the bevel gear set 607, a movable sleeve 603 threadedly connected to the outside of the lead screw 602, an inner tube 604 fixed to the outside of the movable sleeve 603 and slidably connected to the upright 1, and a protective sleeve 605 sleeved on the outside of the upright 1. The outer wall of the lead screw 602 is provided with an external thread, and the inside of the movable sleeve 603 is provided with an internal thread that cooperates with the external thread.

[0046] In this embodiment of the utility model, the drive motor 601 drives the lead screw 602 to rotate through the bevel gear set 607, so that the lead screw 602 drives the moving sleeve 603 to move along the axial direction of the lead screw 602 through the thread engagement, thereby pushing the inner tube 604 to rise and fall, realizing the height adjustment of the top frame 7, and the protective sleeve 605 isolates rainwater, dust and other substances from entering the interior of the upright 1.

[0047] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
