As shown in fig. 2, fig. 3 and fig. 7, the present application further provides a support system for replacing a photovoltaic module, which includes a support base and a support for replacing a photovoltaic module in the above embodiment, the support base includes a support rod 2 that can be inserted along a gap between two adjacent photovoltaic modules, a first end of the support rod 2 is provided with an installation portion for being connected with a support of the photovoltaic module, a second end of the support rod 2 is provided with a support portion, and the support portion extends upwards out of the photovoltaic module and is used for placing the support. The supporting base is simple in structure, the top of the supporting base upwards extends out of the photovoltaic assembly and is used for supporting the workbench, the supporting base is matched with the workbench to be used, and the working efficiency can be effectively improved

Because the main reason of photovoltaic power generation is the total radiant quantity of solar energy, when the photovoltaic module 1 is installed, the photovoltaic module 1 is usually oriented to a direction with sufficient sunlight, so that the photovoltaic module 1 forms a certain slope. When the support is installed, the support needs to be parallel to the surface of the photovoltaic module 1, so that the comfort degree of a worker in the construction process is increased. Therefore, as shown in fig. 3, 4 and 5, the support part of the present application needs to be disposed upward along the inclined surface of the photovoltaic module 1. Specifically, the installation department is the same or opposite with the direction that sets up of supporting part, perhaps supporting part place plane and installation department place plane are perpendicular or become certain angle all can, only need satisfy bracing piece 2 and fix the back on the photovoltaic module support through the installation department, the supporting part upwards sets up along photovoltaic module 1's incline direction can.

As shown in the combined drawings of FIG. 7 and FIG. 8, when the photovoltaic module 1 is arranged in the disassembly and assembly, a worker installs a plurality of supporting bases on the support of the lower photovoltaic module 1, namely fixes the supporting rod 2 on the support of the photovoltaic module 1 through the installation part, and puts the support on the supporting part, so that the worker can operate on the support, the structure is simple, the use is convenient, the labor cost is saved, the lower photovoltaic module 1 is not required to be disassembled, and the working efficiency is increased.

In some embodiments, the mounting portion comprises a clip 3 provided on the side of the support bar 2 for supporting on a support of the photovoltaic module 1 and a locking assembly for defining the position of the clip 3. During the use, the second end of bracing piece 2 passes the gap between two adjacent photovoltaic module 1 to support cardboard 3 on photovoltaic module 1's support, fix the position of cardboard 3 and support through locking Assembly, accomplish the fixed of installation department, the support of this department indicates the I-steel that supports at photovoltaic unit price bottom, puts up cardboard 3 in the top of I-steel base, and locking Assembly presss from both sides the bottom of tight I-steel.

With reference to fig. 2 and 6, the first end of the support rod 2 extends along the radial direction to form a bottom plate 4 (the extending direction of the bottom plate 4 is the same as the setting direction of the clamping plates 3), the locking assembly comprises a limiting rod 5 arranged on the bottom plate 4 in a penetrating manner, and the installation part is fixed on the photovoltaic assembly support by changing the distance between the top ends of the limiting rod 5 and the clamping plates 3.

Wherein, the gag lever post 5 can be the screw rod, be equipped with on the bottom plate 4 with the external screw thread assorted interior swivel nut of screw rod (interior swivel nut can be the same with the thickness of bottom plate 4, perhaps the thickness of swivel nut is greater than the thickness of bottom plate 4 in the end, plays the effect of direction for the rotation and the removal of screw rod), change the length that the screw rod stretches out bottom plate 4 through rotatory screw rod. Specifically, when the screw is rotated forwards, the position of the inner threaded sleeve is unchanged, the screw moves along the length direction of the screw, the screw extends upwards out of the bottom plate 4, and the distance between the end of the screw and the clamping plate 3 is gradually reduced until the bracket is clamped; when dismantling bracing piece 2, the reverse rotation screw rod, the screw rod retracts downwards, and the distance between the tip of screw rod and cardboard 3 is grow gradually, takes off bracing piece 2 can. The design mode is simple in structure and convenient to operate, and can be suitable for various supports with thicknesses.

The limiting rod 5 can also be arranged in a telescopic rod mode, and a power device for driving the end part of the limiting rod 5 to move is arranged on the bottom plate 4. Specifically, the power device is a driving device of the electric push rod, and the telescopic rod can be used as a push rod part of the electric push rod, and the driving device drives the end part of the limiting rod 5 to move upwards or downwards, so that the distance between the top of the limiting rod 5 and the pressing plate 51 is changed. The design mode can realize automatic control, but the use scene is limited, the design mode cannot be used in thunderstorm weather, and the service life is short.

Preferably, a pressing plate 51 for contacting with the support of the photovoltaic module 1 is arranged at one end of the limiting rod 5 facing the clamping plate 3, and the size of the pressing plate 51 is larger than that of the limiting rod 5 of the screw (the pressing plate 51 can be in various shapes such as a circle, a quadrangle and a pentagon). The pressing plate 51 is contacted with the bottom of the support of the photovoltaic module 1, so that the contact area can be effectively increased, and the connection stability is further increased. In order to further increase the contact effect, a rubber sheet may be provided on the end surface of the pressure plate 51 to increase the safety of use.

In other embodiments, the mounting portion may be a base disposed at the bottom of the support rod 2, a screw hole is disposed on the base, a through hole is disposed on the bracket of the photovoltaic module 1, after the support rod 2 is aligned in the mounting position, the screw hole is opposite to the through hole, the locking screw rod is sequentially inserted into the through hole and the screw hole, and the locking screw rod is screwed to complete the mounting of the support rod 2, which is simple in structure and convenient to use.

In other embodiments, the mounting portion may be a base disposed at the bottom of the support rod 2, and a through hole is disposed on the base (the through hole is eccentrically disposed relative to the position of the support rod 2, so that the through hole can be inserted by a screw rod).

The supporting part comprises a first rod piece 6 formed by extending the side surface of the supporting rod 2, and the positioning rod 91 of the bracket is supported at the joint of the first rod piece 6 and the supporting rod 2. Because there is certain angle between photovoltaic module 1 and the ground, when the installation department is fixed back, also there is certain angle between bracing piece 2 and the ground, consequently, set up first member 6 on bracing piece 2 (first member 6 upwards sets up along photovoltaic module 1's incline direction), play the effect of holding beam 91 through the top surface of first member 6 and the side of bracing piece 2, simple and practical.
