Description
Technical field
The invention belongs to environmental monitoring field, are related to a kind of water-quality sampler, for having the water quality sampling of flow such as: entering river
Sewage draining exit, river, Sewage Treatment Plant mouth etc..
Background technique
Traditional water-quality sampler is vertical type water-quality sampler, and sampler is placed in water the weight by sampler tank body
Water is poured in tank body from surrounding by the active force of power and water, there is the water body of certain flow for acquisition, and vertical type sampler is acquiring
In the process, water quality pours in tank body from surrounding, to complete water quality sampling.Such water-quality sampler can acquire certain time point position
The water quality set, but be difficult to obtain some water quality sampling for determining section.
Summary of the invention
The instantaneous water quality of determining position and depth is flowed through for more precise acquisition to required time section, the present invention provides one kind
Structure is simple, convenient for operation, the high fair current water quality synchronized sampler of accuracy.Fair current water quality synchronized sampler of the invention can be with
Overcome upright water-quality sampler drawback, fair current synchronized sampler be placed in water directly to flow through tank body water flow carry out cutting adopt
Sample, section flows through the water quality of some section the time required to more accurately collecting.Technical solution is as follows:
A kind of fair current water quality synchronized sampler including tank body and enters water traction rope it is characterized in that, the lower part in tank body is set
Deflector is set, tank body is the cylinder of two sides opening, is built-in in water inlet into water one-way valve, water outlet is equipped with outside water outlet
Check valve is connected with water outlet traction rope in water outlet.
Preferably, the deflector is one piece of streamline template, and to the back-end from front end, the width of plate is gradually increased.It is leading
Flowing plate is provided with counterweight in tank body lower part.The water inlet of tank body is the lesser cone that is open.It is arranged in the two sides of tank body
There is balance plate 3.Water flow sensing unit is provided on the outside of tank body.
Detailed description of the invention
The structural schematic diagram of fair current water quality synchronized sampler Fig. 1 of the invention.
Detailed description of the invention is as follows:
1 tank body, 2 deflector, 3 balance plate 4 enters water one-way valve 5 and goes out water one-way valve
6 counterweights 7 enter water traction rope 8 and are discharged traction rope
Specific embodiment
Fair current water quality synchronized sampler of the invention specifically includes that cylinder tank body 1, deflector 2, entering built in water inlet
Water one-way valve 4, water outlet external water one-way valve 5, water flow sensing unit (being placed in outside tank body, be not drawn into), two sides balance plate out
3, enter water traction rope 7, water outlet traction rope 8 and the stainless steel weight as counterweight 6.The shape for the check valve that the present invention uses for
Round folded plate is tightly connected by two pieces of semicircular plates.
Working principle: drawing water traction rope and sampler be slowly positioned in water, and deflector makes to justify under the action of water flow
Taper water inlet face water (flow) direction, cylinder is parallel with water (flow) direction at this time, and balance plate, which serves, stablizes sampler, in water flow
It acts on lower water feeding one-way valve to open, water flow is entered, while the water for entering tank body flows through water outlet one-way cock outflow, and device to be sampled exists
After specified sampling section stablizes a few minutes, lifting is discharged traction rope rapidly, and cylinder is upright at this time, and two check valves are in hydraulic pressure
It is closed under reaction force, completes to carry out cutting sampling to flowing through tank body water flow at this time.
Design feature: the center of gravity point of tank body in the middle position of tank body, enter water traction rope be fixed on before and after tank body and
Handover is mutually perpendicular on central point with four points on tank body left-right balance plate, should be located on tank body center of gravity point, portable to make
Tank body is parallel to the horizontal plane when entering water traction rope, to make water flow preferably flow into tank body when sampling；The design of intake is conical,
The impact resistance for reducing water flow makes water flow more smoothly by sampler, make into tank body flow rate of water flow substantially and simultaneously
Section cross-sectional flow is equal, improves the accuracy of synchronized sampling；The water one-way valve that enters of water inlet is set as built-in, primarily to
So that conical water inlet is had certain distance to built-in check valve of intaking, so that water is flowed through conical water inlet and is flowed through a distance and exist again
Check valve is opened under the action of water flow, is avoided water flow from directly acting in outside into water one-way valve, is made under check valve reaction
Water flow is spread to surrounding, cannot be flowed through the water of this section completely into tank body, cannot more accurately be reflected temporal synchronization water sample,
The water quality saved in cylinder at this time is exactly logical period instantaneous water quality substantially；Two sides balance plate make sampler in the water for having flow more
Add steady；Stainless steel weight, when water flow is excessive, sampler cannot be stablized in water body, can install stainless steel weight additional, increase
The weight of sampler；The external water one-way valve out of water outlet, is arranged in outside, more stably flows out tank to flow through the water of tank body
Body；Traction rope setting in external one-way cock dead astern, when Traction rope sampler stand upright under the reaction of hydraulic pressure, two
A closed check valve is completed to carry out cutting sampling to flowing through tank body water flow.Water flow sensing unit is located on the outside of tank body, measures the stream of water
Amount calculates discharge amount convenient for the later period.
