Description

Technical Field

[0001] The present invention relates to the field of pile-based offshore photovoltaic grid transportation sea binding technology, and in particular to a reinforcement device and method for the transportation process of a pile-based offshore photovoltaic support unit. Background Art

[0002] With the rapid development of the offshore photovoltaic industry, temporary reinforcement during the transportation of offshore photovoltaic bracket units has become one of the key links. Due to the complex offshore environment, the construction window is limited. The sea-binding measures during the transportation of large offshore photovoltaic bracket units must ensure both safety and efficiency. However, most temporary sea-binding measures are limited to temporary binding such as wire ropes and slings. Traditional methods are not suitable for the reinforcement of large offshore photovoltaic bracket units during transportation. Welding will damage the parent material of the offshore photovoltaic bracket unit. Repeated welding before transportation and cutting after arriving at the destination will not only waste the limited construction window, but also cause irreversible metal fatigue damage to the transportation tooling, bringing great safety hazards to the transportation of offshore photovoltaic bracket units.

[0003] Therefore, there is an urgent need to design a temporary reinforcement device for pile-based offshore photovoltaic support units during transportation that is safe, reliable, convenient and efficient. Summary of the invention

[0004] The purpose of the present application is to solve the problems existing in the prior art and to provide a reinforcement device and method for the transportation process of pile-based offshore photovoltaic support units.

[0005] The technical solution adopted to achieve the purpose of this application is:

[0007] The fixed buckle plate web of the reinforcement unit is welded to the side of the grid transport tooling; a vertical plug-in portion adapted to the pile-foundation offshore photovoltaic bracket unit node is provided on the top of the grid transport tooling, a flange is provided at the bottom of the pile-foundation offshore photovoltaic bracket unit node, and the serrated linear shape at the bottom of the movable buckle plate web of the reinforcement unit matches the flange.

[0008] In the above technical solution, a plug-in hole is provided on the top of the grid transport tooling, which is vertically plugged into the guide cone at the bottom of the pile-foundation offshore photovoltaic bracket unit node, or a vertical protrusion is provided on the top of the grid transport tooling, which is vertically plugged into the plug-in hole at the bottom of the pile-foundation offshore photovoltaic bracket unit node.

[0009] In the above technical solution, the movable gusset plate web, movable gusset plate wing plates, fixed gusset plate wing plates and fixed gusset plate web are all composed of 15-25 mm thick steel plates.

[0010] In the above technical solution, the sizes of the bolt holes and bolt slots are

[0011] In the above technical solution, the bolt is an M14 bolt.

[0012] A reinforcement method for a pile-based offshore photovoltaic support unit during transportation, comprising the following steps:

[0013] Step 1: vertically dock the top of the grid transport tooling with the bottom of the pile-based offshore photovoltaic support unit node;

[0014] Step 2, placing the movable gusset plate wing plate welded with the movable gusset plate web plate on the fixed gusset plate wing plate, and aligning the bolt holes of the movable gusset plate wing plate with the bolt slot holes of the fixed gusset plate wing plate;

[0015] Step 3, connect the bolt hole and the bolt slot hole through bolts, so as to connect the movable gusset plate wing plate with the fixed gusset plate wing plate, and adjust the movable gusset plate web so that the serrated linear shape at its bottom matches the flange.

[0017] The beneficial effects of the present invention are as follows:

[0018] During the construction of the reinforcement device of the present invention, after the offshore photovoltaic support unit is dropped onto the barge tooling, the movable gusset plate is docked with the fixed gusset plate. Due to a slight deviation between the grid node and the tooling, the movable gusset plate wing is adjusted to make the lower serrated line of the movable gusset plate web coincide with the flange. Finally, four M14 bolts are used to connect the movable gusset plate wing with the fixed gusset plate wing. This device realizes efficient reinforcement of the pile-based offshore photovoltaic support unit and the transport tooling, effectively reduces the grid reinforcement time, and improves the transportation and installation efficiency of the pile-based offshore photovoltaic support unit. The above technical effects make this product suitable for efficient transportation, reinforcement and installation of pile-based offshore photovoltaic support units.
