Description
Technical field
The present invention relates to the device and method that a kind of attached algae gathers, be specifically related to a kind of open fire phase field attached algae collection
Device and method.
Background technology
At present, the acquisition method of attached algae has pasture and water method, microscope slide method and polyester embrane method.Pasture and water method is to be adjusted by collection
Look into the algae of attachment on the aquatic macrophyte in waters, it is not necessary to special sampling instrument.Adopting of microscope slide method and polyester embrane method
Sample instrument, is to be connected by rope, and one end of rope connects float, and the other end of rope connects slide frame or mylar enters
The attachment of row attached algae, it is stipulated that took out slide or thin film from water through 14 days and carry out the collection of attached algae.Attached algae
Being a class plant, illumination is one of important factor in order of its growth and breeding, in raw algae 20cm-50cm waters under water
Growth and breeding better, and sampling apparatus need to be placed in water 14 days；Side from current various collection attached algae
From the point of view of method, having a disadvantage in that the coverage rate such as sampling waters aquatic macrophyte is low, pasture and water method can be restricted；Carry glass
Sheet method and the current sampling tool of membrane process are to connect sampling stand by rope, and sampling stand need to place the time of 14 days in water,
Under conditions of nobody is for keeping an eye on, along with the flowing sampling stand of water can drift about, sampling stand depth in water can be caused to be difficult to
Control in 20cm-50cm waters, it is thus impossible to ensure the attached algae growth and breeding demand to illumination so that gather
Attached algae be not breeding optimum efficiency.To ensure that sampling stand, in 20cm-50cm waters, often needs someone to see
Pipe sampling stand.
Summary of the invention
The present invention solves that existing attached algae collection is to utilize microscope slide method and polyester embrane method, connect sampling stand by rope
Carrying out the collection of attached algae, the flowing of water can cause sampling stand depth in water wayward in 20cm-50cm waters
Problem, it is provided that a kind of open fire phase field attached algae gather device and method.
The present invention is achieved through the following technical solutions:
Harvester: the device of open fire phase field attached algae collection include sampling stand, floating frame, fixed frame, two connecting rods,
Two sleeve pipes, two fixing bars, two baffle plates, two stretch cords, the equidistant bar of at least two and several float, described floating frame
Being four frame structures with described fixed frame, described floating frame and described fixed frame are the most just to setting, and the equidistant bar of at least two sets
Putting between floating frame and fixed frame, and one end of equidistant bar is fixed with floating frame and is connected, the other end of equidistant bar is fixed with fixed frame
Connecting, a length of 20cm-50cm of each equidistant bar, two connecting rods are symmetricly set on the both sides of fixed frame, Mei Gelian
One end of extension bar is fixing with fixed frame to be connected, and the other end of each connecting rod and a fixing connection of sleeve pipe, casing pipe sleeve is contained in solid
In fixed pole, sleeve pipe slides up and down along fixing bar, and two baffle plates are set in parallel on the upper surface of fixed frame, and sampling stand is arranged on
In fixed frame, and sampling stand is bundled with baffle plate by rope, and two stretch cords are set in parallel in the upper surface of sampling stand
On, and the two ends of stretch cord are fixed on fixed frame, on the uniform upper surface being pasted onto floating frame of several floats.
Acquisition method: open fire phase field attached algae gather method through the following steps that realize:
Step one, making harvester: the material of floating frame, fixed frame, connecting rod, sleeve pipe, equidistant bar and baffle plate all uses
PVC, fixing bar is iron, by sampling stand, floating frame, fixed frame, two connecting rods, two sleeve pipes, two fixing bars,
Two baffle plates, two stretch cords, the equidistant bars of at least two have been combined by the structure chart of harvester, do not install in this step
Float；
Step 2, the configuration of float: float is rectangle, its long limit a is 5cm, broadside b is 3cm, high c is 2cm,
The computing formula of float quantity N the following is: N=(1/30) W-4.4 formula one
In formula one:
W sampling stand, floating frame, fixed frame, two connecting rods, two sleeve pipes, the equidistant bar of at least two, two baffle plates
With the gross weight sum of two stretch cords, W unit: gram
When the numerical value using formula one to calculate float quantity N has arithmetic point, the several carries after arithmetic point are rounded,
By on uniform for the N number of float upper surface being pasted onto floating frame；
Step 3, harvester is placed in river: two fixing bars are inserted river bed, and the float quantity in step 2 makes
Sampling stand controls in the waters of 20cm-50cm under water always；
Step 4, taking-up sampling stand: after 14 days, mention floating frame, open stretch cord, take out sampling stand and baffle plate, tear open
Lower baffle plate, takes out the slide in sampling stand, completes attached algae collection.
The present invention compared with prior art has the advantages that
One, two fixing bars of the present invention can be inserted in river bed firmly, and controls sampling stand by float, floating frame and equidistant bar
Being always held in 20cm-50cm waters, sampling stand, under conditions of nobody is for keeping an eye on, is placed in water in the time of 14 days,
Ensure that the attached algae growth and breeding demand to illumination, sleeve pipe drives sampling stand, fixed frame and floating frame along with the fluctuation of water level
And lift.
Two, the present invention keeps an eye on sampling stand without personnel, therefore, reduces sampling cost.
Three, the present invention's is workable, convenient and practical.
