Photovoltaic vegetable water culture device

Abstract

The invention belongs to the field of agricultural equipment, and discloses a photovoltaic vegetable water culture device. The photovoltaic vegetable water culture device comprises a photovoltaic system, a base frame, a bearing frame, cultivating pots, a pumping set, a swinging device, a control unit and a planting formula. The photovoltaic system provides electric energy for the water culture device. The bearing frame comprises a plurality of bearing parts which are parallel and a plurality of vertical rods, the bearing parts are hinged to the vertical rods, the bearing frame and the base frame assembled, a second connecting part in the middle of the bearing frame is hinged to a first connecting part on the top of the base frame, the cultivating pots are placed on the bearing part, the base frame, the bearing parts and the vertical rods form a parallelogram mechanism, and the swinging device is connected with the bearing frame in an assembled manner; and preset values of a liquid supply amount and liquid level are arranged in the planting formula. Based on the planting formula, the control unit controls the pumping set to deliver nutrient liquid and water to the cultivating pots, and therefore, vegetables grow normally; and the water culture device is inclined or upright in a swinging manner, the cultivating pots are successively staggered and stacked again, the spatial attitude of the cultivating pots are always not changed, cultivating liquid in the cultivating pot cannot scattered, and the water culture device cannot roll over easily.

Description

technical field [0001] The invention relates to a hydroponic device, in particular to a photovoltaic vegetable hydroponic device applied to three-dimensional planting of vegetables based on photovoltaic system power supply, and belongs to the field of agricultural equipment. Background technique [0002] In the hydroponic cultivation of vegetables, in order to increase the effective use of space, the cultivation pots are often placed on a vertical cultivation device with a multi-layer structure, and the cultivation pots are stacked on each other to reduce the occupied space and improve the yield per unit space. Yield, but some vegetables cannot get enough sunlight, which affects the normal photosynthesis of vegetables. Therefore, a soilless hydroponic vegetable rack is produced. The vegetable rack can be swung and tilted, and the planting boxes on each layer are staggered in turn, so that the vegetables can get more sunlight; and the original upright state can be restored to...

AI Technical Summary

Problems solved by technology

However, it does not disclose a technical solution for keeping the planting box horizontal; when swinging and tilting, the vegetable rack is prone to rollover, and the planting box is prone to tilting; on the one hand, the tilting of the planting box will easily cause the nutrient solution to spill, and on the other hand, the planting box will The nutrient level on one side of the center is higher than that on the opposite side, which can easily cause uneven nutrients absorbed by the vegetables, resulting in different sizes of finished vegetables

In addition, the existing vegetable rack needs mains power supply, which limits its application range
