Description

Technical Field

[0001] The invention relates to the photovoltaic field, and in particular to a photovoltaic panel array bridge connection structure. Background Art

[0002] At present, with the rapid development of the photovoltaic power generation industry, the photovoltaic power generation industry has become a new trend in the power generation industry at home and abroad with its advantages of environmental protection and high energy quality. However, since the photovoltaic panel arrays used for photovoltaic power generation are usually installed outdoors, outdoor dust, haze, rain, bird droppings, etc. will cause pollution and coverage to the photovoltaic panels, thereby greatly affecting the conversion efficiency of the photovoltaic panels. Therefore, it is necessary to clean the photovoltaic panels regularly.

[0003] In order to realize automatic cleaning of photovoltaic panel arrays, the prior art has proposed photovoltaic panel cleaning machines for various photovoltaic panel arrays, and these photovoltaic panel cleaning machines complete cleaning while moving along the photovoltaic panel array to be cleaned. However, when there is a certain distance between two arrays of photovoltaic panels to be cleaned, the photovoltaic panel cleaning machine cannot cross the span between the two arrays. Therefore, it is necessary to design a bridge connection structure to connect the two photovoltaic panel arrays so that the photovoltaic panel cleaning machine can move between the two arrays.

[0004] However, in order to ensure the maximum power generation effect, many existing photovoltaic panel arrays are equipped with a tracking system, which allows the photovoltaic panel array to rotate and change the inclination of the photovoltaic panel array, so that the photovoltaic panel array is always facing the sun, thereby ensuring the maximum power generation efficiency. However, due to the different positions of two adjacent photovoltaic panel arrays, there may be a certain deviation in the inclination of the two adjacent photovoltaic panel arrays, making it impossible for the two adjacent photovoltaic panel arrays to be aligned, and the existing bridge structure cannot automatically adjust with the change of the inclination of the two adjacent photovoltaic panel arrays, so it cannot be used with photovoltaic panels with a tracking system, which is insufficient. Summary of the invention

[0005] The object of the present invention is to provide a photovoltaic panel array bridge connection structure, which can connect two adjacent photovoltaic panel arrays and automatically adapt to the change of the inclination angle of the two adjacent photovoltaic panel arrays.

[0006] In order to achieve the above object, the solution of the present invention is:

[0007] A photovoltaic panel array bridge connection structure comprises a first fixing rod, a second fixing rod and two connecting rods; wherein the first fixing rod and the second fixing rod are arranged opposite to each other and are used to be respectively installed on two adjacent photovoltaic panel arrays; the two connecting rods are arranged opposite to each other and are respectively located on both sides of the first fixing rod and the second fixing rod; sliding grooves are provided on the opposite inner sides of the two connecting rods along the length direction of the connecting rods, and the two ends of the first fixing rod can be slidably and rotatably inserted into the sliding grooves of the two connecting rods, and the two ends of the second fixing rod can be rotatably matched with the two connecting rods.

[0008] The two ends of the second fixing rod are respectively slidably and rotatably inserted into the sliding grooves of the two connecting rods.

[0011] The two ends of the second fixing rod are rotatably connected to the two connecting rods through a rotatable connection structure.

[0012] The rotating connection structure includes a rotating sleeve and a rotating rod; wherein the rotating rod is fixed on the connecting rod, and the rotating sleeve is coaxially connected to the end of the second fixed rod; the rotating sleeve is provided with an arc-shaped limiting hole along its circumference, the rotating rod can be rotatably inserted into the rotating sleeve, and the rotating rod is equipped with a limiting pin passing through the arc-shaped guide hole, and the limiting pin can slide in the arc-shaped limiting hole along the circumference of the rotating sleeve.

[0013] The rotating connection structure includes a rotating sleeve and a rotating rod; wherein the rotating rod is coaxially connected to the end of the second fixed rod, and the rotating sleeve is fixed on the connecting rod; the rotating sleeve is provided with an arc-shaped limiting hole along its circumference, the rotating rod can be rotatably inserted into the rotating sleeve, and the rotating rod is equipped with a limiting pin passing through the arc-shaped guide hole, and the limiting pin can slide in the arc-shaped limiting hole along the circumference of the rotating sleeve.

[0014] The rotating rod is a hollow structure, and a fixing hole is provided on the side wall of the rotating rod; the limit pin passes through the fixing hole, and the outer end of the limit pin is inserted into the arc-shaped guide hole, and the inner end of the limit pin is formed with a clamping edge for clamping the inner wall of the rotating rod. A spring is fitted in the rotating rod, and the two ends of the spring respectively abut against the limit pin and the inner wall of the rotating rod.

[0015] The limiting pin is threadedly connected to the rotating rod.

[0016] After adopting the above scheme, when the present invention is applied to a photovoltaic panel array, the first fixing rod and the second fixing rod are respectively installed on two adjacent photovoltaic panel arrays, so that the two adjacent photovoltaic panel arrays are connected together, so that the photovoltaic sweeper can move between the two photovoltaic panel arrays along the two connecting rods; and because the two ends of the first fixing rod are respectively slidably and rotatably inserted into the sliding grooves of the two connecting rods, the two ends of the second fixing rod are respectively rotatably matched with the two connecting rods, which allows the two connecting rods to rotate independently. In this way, when the two connected photovoltaic panel arrays of the present invention rotate and the inclination angle of the photovoltaic panel array changes, the two connecting rods will rotate independently so that the two connecting rods can maintain the connection with the first fixing rod and the second fixing rod, so as to automatically adapt to the change of the inclination angle of the two adjacent photovoltaic panel arrays.
