Soilless cultivation siamesed intelligent pipeline containing micro-nanobubble device

Abstract

The invention discloses a soilless cultivation siamesed intelligent pipeline containing a micro-nanobubble device. The pipeline comprises culture tubes, square tubes, adaptor tubes, dissolved oxygen sensors, bubble water inlet pipes and tube plugs which are in series connection in sequence, both ends of each culture tube are provided with integrated square tubes, the tops of the square tubes are provided with detection holes, the dissolved oxygen sensors are placed in the detection holes, two sets of grooves in mirror symmetry are formed in each square tube, sealing parts are placed in the twosets of grooves, each sealing part is fixedly connected to one end of a corresponding elastic cushion, the other end of the corresponding elastic cushion is fixedly connected with a groove, each sealing part is provided with a taper hole, and each taper hole abuts the lower portion of the corresponding dissolved oxygen sensors. The soilless cultivation siamesed intelligent pipeline containing themicro-nanobubble device has the advantages that the structure is simple and clear, the dissolved oxygen amount in the effluent water can be measured in real time through the dissolved oxygen sensorsat the two ends of each culture tube, a sufficient number of micro-nanobubbles can be provided for hydroponic plants in an intelligent and accurate mode, the use of the device is simple, the installation is easy, and the growth and development speed of the hydroponic plants are quick.

Description

technical field [0001] The invention relates to the technical field of soilless cultivation, in particular to a connected intelligent pipe for soilless cultivation containing a micro-nano bubble device. Background technique [0002] Usually we call the existence of gas in liquid as bubbles. The formation of bubbles can be encountered in many processes in nature. When the gas is subjected to shear force in the liquid, bubbles of different sizes and shapes will be formed. The so-called micro-nano bubbles refer to bubbles with a diameter of about ten microns to hundreds of nanometers when the bubbles occur. This kind of bubbles is between micro-bubbles and nano-bubbles. Compared with conventional bubbles, its gas dissolution rate is higher. [0003] In the production process of hydroponic plants, the amount of dissolved oxygen in water is an important factor affecting the growth and development speed. Sufficient dissolved oxygen leads to faster growth, and low dissolved oxygen...

Problems solved by technology

[0003] In the production process of hydroponic plants, the amount of dissolved oxygen in water is an important factor affecting the growth and development speed. Sufficient dissolved oxygen leads to faster growth, and low dissolved oxygen not only slows growth, but is also lower than the critical value of dissolved oxygen required by plants. There will be rotten roots due to hypoxia, so in terms of production, increasing dissolved oxygen in water is the main technology of hydroponics. No matter how diverse the cultivation mode is in the circulation mode, it is ultimately based on the improvement of dissolved oxygen as a guarantee for the feasibility of its model. However, there is a lack of detection devices in the existing technology, which can measure the dissolved oxygen in water for hydroponic plants in real time
