Abstract
The utility model relates to a fixed-point water quality sampler which is provided with a barrel body. The lower bottom of the barrel body is provided with a water inlet, and the upper top is provided with a water drainage outlet. The inner surface of the bottom of the barrel body is provided with an inlet valve for covering the water inlet, and the top of the barrel body is provided with a drainage valve for covering the water drainage outlet. A handle is hung at the upper end of the barrel body by hooks at two sides, and a connecting rod is connected between the inlet valve and the drainage valve. The fixed-point water quality sampler has a simple structure and is easy for operation. The fixed-point collected water sample has high precision, and the fixed-point water quality sampler is convenient for the water quality inspection department to use.
Description
Technical field:
The utility model relates to a kind of water quality grab sampling device, is used for gathering the check water sample.
Background technology:
Present widely used water-quality sampler is the sampling thief of bivalve up and down, is provided with water intaking valve in the cylindrical shell bottom of sampling thief, is provided with draining valve at the top.When sampling thief is put into water, sampling thief relies on deadweight to sink, liquid backs down the water intaking valve of bottom, water sample is continuously flowed in the sampling thief cylindrical shell automatically with constantly transferring of sampling thief, when sampling thief submerged, draining valve was opened, and sampling thief continues to sink, liquid then constantly flows into cylindrical shell by the water inlet of bottom, and is flowed out by the freeing port at top.When the sampling thief stop motion, water intaking valve and draining valve rely on deadweight to fall back to original position, close water inlet and freeing port, thereby finish sampling action.Though the imagination water sample is to continuously flow in cylindrical shell and outflow continuously, but reality is owing to the reason of the gravity and the inner barrel resistance of draining valve, the rate of sinking of sampling thief can not be mated with the inflow and outflow of water sample, thereby the sample of gathering will be the compound sample of different depth, can't reach the effect of spot sampling, this representativeness of taking a sample not strong, especially when water sample concentration changed greatly with the depth of water, error was bigger.
Summary of the invention:
The purpose of this utility model provides a kind of water quality grab sampling device, can realize grab sampling, and sampling degree of accuracy height is simple to operate, convenient and practical, cheap.
The purpose of this utility model realizes as follows: have the water inlet of going to the bottom, a Shang Ding that the cylindrical shell of freeing port is arranged, the bottom inner face of cylindrical shell is provided with the water intaking valve that covers water inlet, the top of cylindrical shell is provided with the draining valve that covers freeing port, the upper end of cylindrical shell articulates handle by the hanging nose of both sides, is connected with connecting rod between water intaking valve and the draining valve.Effect by connecting rod opens and closes water intaking valve and draining valve synchronously, avoids draining valve to close in advance because of gravity, and the water sample of inflow and outflow is complementary.
Hangers is set below the draining valve, hangers is set down above the water intaking valve, the upper end of connecting rod and last hangers are hinged, and the lower end of connecting rod is connected with the slide opening of following hangers.The employing slide opening connects, and avoids reason because of foozle to make water intaking valve and draining valve interfere the wherein phenomenon that can not close fully of a valve of appearance mutually.
Cylindrical shell bottom side has the dewatering outlet, and capping is set on the dewatering outlet, opens capping and can take out water sample.
The utility model is simple in structure, operation easily, and fixed point is gathered water sample degree of accuracy height, is convenient to water examination department and uses.
Description of drawings:
Accompanying drawing is a structural representation of the present utility model.
Embodiment:
With reference to accompanying drawing, the water inlet 1 of having gone to the bottom is arranged, there is the cylindrical shell 6 of freeing port 9 on last top, the bottom inner face of cylindrical shell 6 is provided with the water intaking valve 2 that covers water inlet 1, the top of cylindrical shell 6 is provided with the draining valve 10 that covers freeing port 9, the upper end of cylindrical shell 6 articulates handle 12 by the hanging nose 11 of both sides, hangers 8 is set below the draining valve 10, hangers 5 is set down above the water intaking valve 2, other has a connecting rod 7, the upper end of connecting rod 7 and last hangers 8 are hinged, and the lower end of connecting rod 7 is connected with the slide opening of following hangers 5, and cylindrical shell 6 bottom sides have dewatering outlet 3, capping 4 is set on dewatering outlet 3, and capping 4 and dewatering outlet 3 are by being threaded.
