Abstract: An installation assembly for a photovoltaic module comprises a base plate, a pressing block, a elastic member, and a connecting member. The base plate comprises a connecting portion. The pressing block comprises a pressing portion, a supporting portion, and a sliding portion. The sliding portion is movably connected to the base plate. The elastic member is located between the connecting portion and the supporting portion. The connecting member sequentially inserted into the pressing block, the elastic member, and the base plate. The pressing block, the elastic member, and the base plate are positioned between two ends of the connecting member.

Abstract: A support assembly for supporting photovoltaic panels includes a plurality of support units connected one by one. Each of the plurality of support units includes a support beam, a pair of standing posts, a strengthening bar and at least one horizontal beam. The pair of standing posts, the strengthening bar and the at least one horizontal beam are pivotably mounted on the support beam via connecting members. When used, the strengthening bar rotates relative to the support beam and collectively constitutes a triangle with the support beam and one of the pair of standing posts to avoid distortion. When packaged, the pair of standing posts and the strengthening bar rotate relative to the support beam to be received in the receiving groove respectively, and the at least one horizontal beam rotates relative to and is disposed in parallel to the support beam.

Abstract: A cleaning vehicle includes a vehicle body, a cantilever system, and a cleaning apparatus. The cantilever system includes a rotary table fixed on the vehicle body, a first cantilever pivotably mounted on the rotary table, and a second cantilever pivotably connected to the first cantilever. The cleaning apparatus is fixed to one end of the second cantilever opposite to the first cantilever. The cantilever system further includes a first adjusting pole, a second adjusting pole, and a third adjusting pole, for adjusting the position and the angle of the cleaning apparatus.

The cleaning apparatus is fixed to one end of the second cantilever opposite to the first cantilever. The cleaning apparatus includes a bracket, a sweeping unit rotatably mounted to the bracket, a blower-vacuum unit, and a spraying unit.

Abstract: A photovoltaic module includes a photovoltaic sheet and a number of bars around the photovoltaic sheet. Each bar includes a supporting plate and a locking plate. A channel is defined between the supporting plate and the locking plate, to receive an edge of the photovoltaic sheet. One of the bars arranged at a bottom of the photovoltaic module defines at least one discharge groove, communicating with the channel, which causes accumulating grime and dirt to be thrown off by the action of rain or by cleaning.

Abstract: An assembling tool includes a supporting plate, a positioning plate extending up perpendicularly from a first end of the supporting plate, a U-shaped locking plate extending down from a second end of the supporting plate, and an operation portion attached to a bottom of the locking plate.

Abstract: A locking apparatus includes a bracket, a pressing member, a mounting member, and a screw. The bracket includes two sidewalls and a guiding portion between the sidewalls. The guiding portion includes two opposite side plates and an arc-shaped linking portion. A blocking portion is formed at a joining portion between a top portion of each side plate and a top portion of the corresponding sidewall. An access is defined between the blocking portions. The mounting member includes a rectangular flat top surface and an arc-shaped bottom surface. A screw hole is defined in the mounting member through the top and bottom surface. The mounting member is placed into the guiding portion through the access. The linking portion mates with the bottom surface to guide the top surface facing the access. The screw extends through the pressing member and the access to screw into the screw hole.

Abstract: A supporting apparatus includes a first pole, a second pole, a connecting pole, a reinforcing pole, and a fastener. A first end of the reinforcing pole is connected to a first end of the first pole. A first end of the connecting pole is connected to a second end of the first pole. A first end of the second pole is connected to a second end of the connecting pole. A second end of the reinforcing pole is connected to a middle of the first pole through the fastener. The connecting pole and the first pole each have a U-shaped cross-section. When the fastener is released from the first pole, the reinforcing pole is rotated to be received in the first pole. The reinforcing pole and the first pole are then rotated to be received in the connecting pole.
