Description
TECHNICAL FIELD
[0001] The utility model relates to photovoltaic power generation technical field, concretely relates to a waterproof device for flexible solar photovoltaic support anchor rod. BACKGROUND
[0002] With the rapid development of photovoltaic industry, the single-layer suspension system commonly used in civil buildings and bridge structures is introduced into photovoltaic power generation projects, which is collectively referred to as flexible solar photovoltaic support. Compared with the traditional fixed photovoltaic support, the flexible support has obvious advantages and can adapt to more topography and application conditions. Water photovoltaic has also become a mainstream form. Water photovoltaic exists water flow erosion to anchor rod, usually increases pile length, makes anchor rod above water surface, which causes pile length too long and increases cost. SUMMARY
[0003] In view of the above, the utility model wants to solve the technical problem, provide a waterproof device for flexible solar photovoltaic support anchor rod, can effectively reduce the diameter of pile length and pile, reduce overall cost.
[0004] The utility model is such implementation, a waterproof device for flexible solar photovoltaic support anchor rod, including installation with steel bottom plate, steel sleeve, conical pipe, steel bottom plate is the circular ring steel plate with center hole, along the circular ring steel plate's ring surface is opened multiple mounting holes;Steel sleeve is the circular tub with the bottom at top, and the bottom without bottom, steel sleeve bottom has flange, steel sleeve side wall has the through -hole of installation conical pipe, and the mounting hole on flange corresponds with the mounting hole on steel bottom plate, and the steel sleeve that is sleeved on the prefabricated pile head is connected with the steel bottom plate that is sleeved on the outer wall of prefabricated pile through the bolt in the mounting hole, and the anchor rod fixed on the prefabricated pile passes through conical pipe, and the water-swelling glue is poured in the gap between the outer wall of prefabricated pile and the inner wall of steel sleeve.
[0005] As the outer edge of the circular ring steel plate of the steel bottom plate is turned up at least 500mm, the circular ring steel plate is uniformly opened with multiple mounting holes.
[0006] The flange outer diameter of the steel sleeve bottom is less than the inner diameter of the turned up circular ring steel plate of the steel bottom plate.
[0007] The conical pipe is welded with the steel sleeve.
[0008] The utility model has the advantages and technical effects of blocking water flow erosion to anchor rod, improving anchor rod and pile body combination, and reducing pile diameter and pile length. BRIEF DESCRIPTION OF DRAWINGS
