Abstract

The invention relates to a reusable biological floating bed which is characterized by consisting of a frame, a net cage and net sheets. The net cage and the net sheets are respectively fixed on the frame by nylon ropes. The frame the depth of which is 20cm is made of PVC pipes with the diameter of 50mm and is rectangular or square; and the area of the frame can be determined according to the requirement. The net sheets on the upper layer are used for fixing plants and the mesh diameter of the net sheets is about 2cm; and the mesh diameter of the net cage is about 2mm and the net cage is used for protecting the roots of the plants. The reusable biological floating bed has the following advantages: firstly, the floating bed is light, convenient to assembly, disassembly and reuse; secondly, with the net cage design, the floating bed is beneficial to protecting the roots of the plants; and thirdly, the middle of the floating bed frame has a double-layer net sheet structure, so the floating bed has stronger transmittance compared with the traditional used foam plate and is beneficial to growth of fishes and planktons in water.

Description

Reusable biologic float bed

Technical field

This invention belongs to the water body purification technical field, specifically is exactly that a kind of energy that utilizes plastics tubing, net sheet and net cage to combine is reusable biologic float bed.

Background technology

Biologic float bed being meant on the water surface of eutrophication water with the floating bed is carrier, the waterplant or the damp tolerant plant of plantation well developed root system.By part nutritive salt, toxic substance in plant roots and stems absorption, the adsorbed water body, reduce concentration of nitrogen and phosphorus in the water body, and absorption is accumulated in the root system of plant surface and the intravital pollutent of plant shifts out water body, thereby reduce the water eutrophication degree by the form of results plant materials.Simultaneously, the waterplant of biologic float bed plantation has higher sight, is applicable to city inland river, lake, outskirts of a town and the landscape water body of pollution is arranged.At present biologic float bed by making based on the light material of porous plastics, bamboo raft or synthetic material.Mainly do framework with mao bamboon, porous plastics is done the carrier of plant growing, and the mao bamboon framework of this floating bed is apt to rot, often just can not use again in 1 year, and relatively heavier, be difficult for laying.

Summary of the invention

In order to solve the at present biologic float bed present situation that can not reuse, be difficult for laying, it is reusable biologic float bed to the invention provides a kind of energy that utilizes plastics tubing, net sheet and net cage to combine, be convenient to installation and removal, can reuse, guaranteed that plant plants the surviving rate after floating bed.

The technical scheme that technical solution problem of the present invention is adopted is: a kind of reusable biologic float bed, form by framework and plant growing carrier, it is characterized in that the plant growing carrier is one deck net sheet and is fixed on the framework with nylon rope, also is fixed with sagging net cage with nylon rope on the framework; Framework is made of plastics tubing.Preferably, net cage degree of depth 20cm, mesh diameter are 2mm, and net sheet mesh diameter is 2cm; The framework diameter is that the pvc pipe of 50mm is made.The net sheet is in order to plantation, fixing plant, and net cage is in order to the protective plant root.Frame shape is rectangle or square, and the big I of frame area is determined as required.

This biologic float bed making has the following advantages: the one, and used pvc pipe corrosion resistant is mashed, and is light, is convenient to install, the repeated use of dismounting and floating bed; The 2nd, adopt the net cage design to help the protection of plant root; The 3rd, be the Double-level Reticulated chip architecture in the middle of the floating bed framework, stronger than the light transmission of the cystose of original use, help water body Mesichthyes and planktonic growth.

Embodiment

The invention will be further described below in conjunction with accompanying drawing.

Among Fig. 1, framework 1 is a rectangle, uses diameter to be 50mm pvc pipe and bonding the forming of elbow that match with it.Net sheet 2 directly tension is fixed on the framework 1 with nylon rope, and its mesh is 2cm.Net cage 3 is made into thin nylon rope according to frame size, and the dark 20cm of case, mesh 2mm are fixed on the framework 1 with thicker nylon rope all around, pulls down after being convenient to use up then to clean and uses the coming year again.

Before this biologic float bed use, at first select to determine the plant that to cultivate, be placed on earlier after transporting back to cultivate in the pond to root system and germinate.Keep flat on the ground biologic float bed again, the plant that cultivate is fixed in the mesh of net sheet 2,2-3 of each mesh internal fixing, spacing 20cm * 20cm is till whole floating bed planted.The effect of net cage 3 is protective plant roots.With having planted the biologic float bed water body that will purify of putting into of plant, with nylon rope each floating bed is connected together, form a row or several rows, more every row's floating bed two ends are fixed on the bank.

Treat annual winter, behind the plant harvesting with plantation, whole floating bed can be shifted out the water surface.With the net cage dismounting, clean net cage, framework and net sheet with high-pressure water tap, to dry, store, the coming year is reusable.

Claims

One kind reusable biologic float bed, form by framework and plant growing carrier, it is characterized in that the plant growing carrier is one deck net sheet and is fixed on the framework with nylon rope, also is fixed with sagging net cage with nylon rope on the framework; Framework is made of plastics tubing.
2. as claimed in claim 1 reusable biologic float bed, it is characterized in that the described net cage degree of depth is 20cm, mesh 2mm; Net sheet mesh 2cm; The framework diameter is made for the 50mmPVC pipe.
