Description

Technical Field

[0001] The utility model relates to the technical field of flexible photovoltaic panel brackets, in particular to a windproof tensioning and compensating device for traction of a flexible photovoltaic panel bracket. Background Art

[0002] Photovoltaic panel brackets are the basic supporting components for outdoor installation of photovoltaic panels. Photovoltaic panel brackets can be used to install and distribute photovoltaic panels with reasonable spacing and improve the adaptability of photovoltaic panels to the environment.

[0003] For example, the Chinese invention patent with authorization announcement number CN113904616B: A flexible photovoltaic bracket discloses a plurality of first support components and a plurality of cable components, the cable components are sequentially arranged between the first support components, and a plurality of photovoltaic components are arranged on the cable components; by utilizing the setting of the lower chord, a downward pulling force can be provided to the cable component through the frame, so that the flexible photovoltaic bracket can maintain good working ability when subjected to upward wind load.

[0004] The above-mentioned invention patent has a strong adaptability to upward wind loads, but the traction force at both ends of the connecting cable is fixed, and the traction force cannot be adaptively adjusted according to changes in environmental wind force to reduce the probability of damage to the photovoltaic panels and brackets. Therefore, this field urgently needs a flexible photovoltaic panel bracket traction windproof tensioning compensation device to solve the problems existing in the prior art. Utility Model Content

[0005] The utility model aims to provide a flexible photovoltaic panel support traction windproof tension compensation device to solve the problem that the connecting rope of the photovoltaic panel support in the prior art cannot make adaptive adjustment to the traction force according to the change of environmental wind force.

[0006] In order to achieve the above-mentioned purpose, the utility model provides the following technical solutions: a flexible photovoltaic panel bracket traction windproof tension compensation device, including a main column, a crossbeam fixedly installed on the main column, a cable supported and fixed on the crossbeam, a photovoltaic panel fixedly installed on the cable, a pull rod fixedly supported on one side of the main column, and the cables of all photovoltaic panel brackets are commonly limited and connected with a connecting cable. When the photovoltaic panel and the bracket are swept by wind, the connecting cable limits the cable, which can effectively reduce the swing amplitude of the cable and the photovoltaic panel, and the two ends of the connecting cable are traction-connected with a tension compensation device; under the traction action of the tension compensation device, the connecting cable is horizontally stretched and straightened, so that the connecting cable is difficult to swing, and then the cable is difficult to swing. The cam is provided with a plurality of movable pulleys, and the movable pulleys are provided with a plurality of movable pulleys, and the movable pulleys are provided with a plurality of movable pulleys.

[0007] A traction rope is wound and installed on the pulley block, and a counterweight is suspended downward from the pulley groove of the first fixed pulley at one end of the traction rope for traction application, and a traction engagement piece is connected and fixed to the side of the movable pulley bracket close to the connecting rope, and the traction engagement piece is fixedly connected to the end of the connecting rope; when the connecting rope is in a straight state, the connection point between the traction engagement piece and the connecting rope is located in the same horizontal plane as the connecting rope;

[0009] By adopting the above technical scheme, the steering function of the fixed pulley and the labor-saving effect of the movable pulley are utilized, and the counterweight is used as a power source to pull the two ends of the connecting cable. By changing the weight of the counterweight, the connecting cable can be made to have different degrees of tension, and then the tension of the connecting cable can be adjusted according to the wind force in the environment. This can avoid the phenomenon that ① the connecting cable is easily broken due to the high tension in a strong wind environment, and ② the connecting cable is easily swung due to the low tension in a small to medium wind environment, resulting in poor fixation of the photovoltaic panel.

[0010] As a preferred solution, the connection point between the traction connector and the connecting rope, the center point of the first fixed pulley, the center point of the second fixed pulley, and the center point of the third movable pulley are located in a straight line, making the pulleys less susceptible to oblique pulling forces based on the horizontal plane, thereby reducing maintenance costs.

[0011] As a preferred solution, a guide plate is fixedly installed at one end of the mounting plate away from the side column, and a guide hole is horizontally penetrated through the guide plate at the same height position as the connection point of the traction engagement member and the connecting cable, and the connecting cable passes through the inside of the guide hole. The guide hole, the connection point of the traction engagement member and the connecting cable, the center point of the first fixed pulley, the center point of the second fixed pulley, and the center point of the third movable pulley are located in a straight line;

[0012] By adopting the above technical solution, the connecting rope can be prevented from being swung by wind, and an oblique pulling force based on the horizontal plane is generated on the third movable pulley, so that the pulley block is not easily damaged and the maintenance cost is reduced.

[0013] As a preferred solution, a reinforcing rod is fixedly supported between the guide plate and the mounting plate to improve the stability of the guide plate structure.

[0014] As a preferred solution, the counterweight is a counterweight box, a box cover is provided at the top of the side wall of the counterweight box, and a bottom plate is detachably installed at the bottom of the counterweight box. When the traction force on the connecting rope needs to be increased, the box cover is opened to add a solid or fluid that can be counterweighted into the counterweight box; when the traction force on the connecting rope needs to be reduced, the bottom plate is opened to allow part of the solid or fluid inside the counterweight box to leak out;

[0015] By adopting the above technical solution, the weight of the counterweight can be adjusted flexibly and the range of counterweight objects can be wide. Stones, sand and water sources existing at the installation site can be directly used as counterweights, reducing the labor intensity of preparatory work before installation.

[0016] As a preferred solution, the side columns are made of steel; and the mounting plate is made of steel.

[0017] As a preferred solution, a support rod is fixed to the middle part of the side wall of the side column close to the connecting cable, and one end of the support rod away from the side column is fixed to the ground support.

[0018] As a preferred solution, a support rod is fixedly connected between the side wall of the side column and the bottom surface of the mounting plate, and the support rod can improve the stability of the side column supporting the mounting plate.

[0019] As a preferred solution, the traction rope is a steel wire rope.

[0022] 2. This scheme designs a pulley block as a link of power transmission, which can effectively pull the connecting rope with a small counterweight.

[0023] 3. The counterweight box designed in this solution has high flexibility in adjusting the counterweight weight and a wide range of counterweight objects. It can directly use the stones, sand and water sources at the installation site as counterweights, reducing the labor intensity of the preparatory work before installation.

[0024] 4. The sliding traction method of the connecting cable end of this solution overturns the traditional rigid connection method, so that the connecting cable can offset a greater force when affected by strong winds, making the connecting cable less likely to be damaged and reducing the maintenance cost of the photovoltaic panel bracket.

[0032] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0033] like Figure 1-4 As shown, the flexible photovoltaic panel bracket traction windproof tension compensation device includes a main column 101, a crossbeam is fixedly installed on the main column 101, a cable 103 is supported and fixed on the crossbeam, a photovoltaic panel is fixedly installed on the cable 103, and a pull rod 102 is fixedly supported on one side of the main column 101. The cables 103 of all photovoltaic panel brackets are commonly limited and connected with a connecting cable 104. When the photovoltaic panel and the bracket are swept by wind, the connecting cable 104 limits the cable 103, which can effectively reduce the swing amplitude of the cable 103 and the photovoltaic panel, and the two ends of the connecting cable 104 are traction-connected with a tension compensation device 201; under the traction action of the tension compensation device 201, the connecting cable 104 is horizontally stretched and straightened, so that the connecting cable 104 is difficult to swing, and then the cable 103 is difficult to swing due to external force. The tension compensation device 201 comprises a side column 301 fixedly connected to the ground at the bottom end; a mounting plate 302 is fixedly installed on the top of the side column 301 near the side of the connecting cable 104, and a pulley group is installed on the upper surface of the mounting plate 302, and the pulley group comprises a first fixed pulley 304, a second fixed pulley 305, and a third movable pulley 306; a first fixed pulley 304 is fixedly installed on the end of the upper surface of the mounting plate 302 near the side column 301 by means of a pulley bracket, a second fixed pulley 305 is fixedly installed on the middle part of the upper surface of the mounting plate 302 by means of a pulley bracket, a slide rail 307 is fixedly installed on the end of the upper surface of the mounting plate 302 away from the side column 301, a slider is slidably installed on the slide rail 307, a movable pulley bracket is fixedly connected to the top of the slider, and a third movable pulley 306 is installed on the movable pulley bracket;

[0034] A traction rope 308 is wound and installed on the pulley block, and one end of the traction rope 308 for traction force is suspended downwardly from the pulley groove of the first fixed pulley 304 with a counterweight. A traction connecting piece 401 is connected and fixed to the side of the movable pulley bracket close to the connecting rope 104, and the traction connecting piece 401 is fixedly connected to the end of the connecting rope 104; when the connecting rope 104 is in a stretched state, the connection point between the traction connecting piece 401 and the connecting rope 104 is located in the same horizontal plane as the connecting rope 104.

[0035] By adopting the above technical scheme, utilizing the steering function of the fixed pulley and the labor-saving effect of the movable pulley, the counterweight is used as a power source to pull the two ends of the connecting rope 104. By changing the weight of the counterweight, the connecting rope 104 can be made to have different degrees of tension. Then, the tension of the connecting rope 104 can be adjusted according to the wind force in the environment, thereby avoiding ① the high tension of the connecting rope 104 in a strong wind environment, which leads to easy breakage, and ② the low tension of the connecting rope 104 in a small to medium wind environment, which leads to easy swing of the cable 103 and the photovoltaic panel, and poor fixation of the photovoltaic panel.

The guide plate 402 is provided with a guide hole 403 horizontally penetrating at the same height position as the connection point between the traction coupling member 401 and the connecting cable 104.

[0038] By adopting the above technical solution, the connecting rope 104 can be prevented from being swung by wind, and an oblique pulling force based on the horizontal plane is generated on the third movable pulley 306, so that the pulley block is not easily damaged and the maintenance cost is reduced.

[0039] A reinforcing rod 404 is fixedly supported between the guide plate 402 and the mounting plate 302 to improve the stability of the guide plate 402 structure.

A bottom plate is detachably installed at the bottom of the counterweight box 501.
