[0013] In summary, the utility model has the following beneficial effects:

[0014] 1. The frame tube is set on the upper surface of the cover plate, and the connection sleeve is set on the frame tube and positioned using the positioning piece. Then the installation groove on the mounting plate can be used for the solar panel to be embedded. The wires of the solar panel pass through the waist-shaped hole and the opening groove and enter the frame tube. The wires pass through the frame tube and connect to the lithium battery in the connection box. At this time, the position of the solar panel can be elevated, and finally the impact of the surrounding crops on the solar panel can be reduced, which is conducive to the stable reception of light by the solar panel.

[0015] 2. The wires of the solar panel are inserted into the high-pressure rack, so that the wires are wrapped and protected by the high-pressure rack.

[0016] 3. The two ends of the bidirectional screw are threadedly connected to the internal thread sleeves of the two clamping arms. At this time, the two clamping arms can be driven to move toward the side away from or close to each other by rotating the bidirectional screw. When the two clamping arms move toward the side close to each other, the clamping arms can be pressed against the frame tube, and then the clamping arms can be locked on the frame tube. At this time, the clamping arms can play a role in positioning the upper connecting sleeve;

[0017] At the same time, by rotating the two-way screw rod to drive the two clamping arms to move away from each other, the clamping arms can move up and down along the frame tube, and the connecting sleeve on the frame tube can be moved at this time, so as to move the solar panel up and down. When it moves to a suitable height, the clamping arms can be locked on the frame tube again to locate the position of the moving connecting sleeve, and finally the height of the solar panel can be adjusted according to the height of the branches and leaves of the surrounding crops, so as to ensure that the solar panel will not be affected by the crops.

[0018] 4. When the bidirectional screw needs to be rotated, the rotating nut on the bidirectional screw can be used to conveniently rotate the bidirectional screw;

[0019] 5. Use the side of the mounting plate to cover the upper end of the frame tube. At this time, the mounting plate can shield the upper end of the frame tube, thereby further reducing the possibility of rainwater entering the frame tube and then seeping into the connection box;

[0020] 6. The frame high pipe is threadedly connected to the internal thread ring on the cover plate by using the external thread ring, so that the frame high pipe can be detachably connected to the cover plate, which is ultimately conducive to the rapid disassembly and assembly of the frame high pipe.
