Abstract
The utility model relates to a bubble-free water sampling device for experiment teaching. The bubble-free water sampling device comprises a water sample chamber, a counter weight chamber, a bottle stopper, a water inlet pipe, a valve arranged on the water inlet pipe, an exhaust pipe, a valve arranged on the exhaust pipe, an exhaust hose, a valve arranged on the exhaust hose and a rope tying ring. The device is integrated; a main body of the device is composed of the water sample chamber, the counter weight chamber and the bottle stopper; the water inlet pipe and the exhaust pipe are provided with the valves and are also inserted to the water sample chamber through the bottle stopper; then, the exhaust hose is connected with the exhaust pipe arranged on the device and the valve arranged on the exhaust hose. The device is light in parts, small in floor area, low in cost as well as flexible and convenient to carry.
Description
Technical field
The utility model relate in a kind of experimental teaching without bubble water sample acquisition device.
Background technology
In the experimentation of water analysis, often can relate to the collection of water sample, have in the market the more complicated automatic sampler of various structures, electronic sampling thief etc., but their prices are more expensive and heavy again, be not suitable for large area and use; And the more cheap conventional water sampling device of price is the weight of wide-mouth vial and iron, this sampling cartridge is equipped with and carries inconvenience, uses trouble, simultaneously frangible, student, sample the non-constant of operability in experiment, thus design in a kind of experimental teaching without bubble water sample acquisition device.This device is made of one sampling bottle and counterweight, and volume is little, and cost is low, simple to operate convenient again, is convenient to student and samples in natural water, thereby reduce the difficulty of sampling.This device is particularly suitable for the collecting work of field water sample in college experiment teaching, can be used for the water sampling of general applications, also can be used for as measured the collection of the water sample of the specific (special) requirements such as dissolved oxygen DO, so can be widely used in the monitoring Shi Deng department of environmental monitoring department and sewage treatment plant's (station).
Summary of the invention
The purpose of this utility model is to provide a kind of volume little, in a kind of experimental teaching easily again simple to operate without bubble water sample acquisition device.
In the experimental teaching the utility model proposes without bubble water sample acquisition device, by water sample chamber 1, counterweight chamber 2, bottle stopper 3, water inlet pipe 4, on water inlet pipe, valve 5, gas outlet 6, on gas outlet, valve 7, valve 9 on exhaust hose 8 and exhaust hose forms, water sample chamber 1 is positioned at 2 tops, counterweight chamber, water sample chamber 1 and counterweight chamber 2 are connected, bottle stopper 3 is positioned at water sample chamber 1 upper bottle port part, water sample chamber 1 is inserted through bottle stopper 3 in water inlet pipe 4 and gas outlet 6 one end, and water inlet pipe 4 ends are positioned at water sample chamber 1 inner bottom part, gas outlet 6 connects exhaust hose 8 one end by valve on gas outlet 7, exhaust hose 8 other ends are provided with the valve 9 on exhaust hose, water inlet pipe 4 is provided with valve 5 on water inlet pipe.
In the utility model, water sample chamber 1 top symmetria bilateralis is furnished with tether subring 10.
In the utility model, described water inlet pipe 4 entrance points are downwards crooked, can prevent that floating thing from directly entering in bottle during water sampling; Endpiece is near 1 bottom, water sample chamber, and parallel with 1 bottom, water sample chamber, can prevent from sneaking in sample bubble during water sampling.
The beneficial effects of the utility model are that assembly is light, floor area is little, cost is low, carries flexible.
Accompanying drawing explanation
Fig. 1 is structural diagrams of the present utility model.
Number in the figure: the valve on valve, 8 exhaust hoses, 9 exhaust hoses, 10 tether subrings on valve, 6 gas outlets, 7 gas outlets on 1 water sample chamber, 2 counterweight chambers, 3 bottle stoppers, 4 water inlet pipes, 5 water inlet pipes.
Embodiment
Below by embodiment, further illustrate by reference to the accompanying drawings the utility model.
Embodiment 1: as shown in Figure 1, and being made by organic glass without bubble water sample acquisition device in experimental teaching.By the valve 9 on valve 7, exhaust hose 8, exhaust hose on valve 5, gas outlet 6, gas outlet on water sample chamber 1, counterweight chamber 2, bottle stopper 3, water inlet pipe 4, water inlet pipe and tether subring 10, its structure as shown in Figure 1.This device is single unit system, main body is comprised of water sample chamber 1, counterweight chamber 2 and bottle stopper 3, water sample chamber 1 is positioned at 2 tops, counterweight chamber, be connected, water sample chamber 1 top bottle mouth position arranges bottle stopper 3, water inlet pipe 4, gas outlet 6 insert water sample chamber 1 through bottle stopper 3 with valve simultaneously, then by the valve 9 on gas outlet 6 and exhaust hose on exhaust hose 8 coupling arrangements, are furnished with tether subring 10 in main body.
The course of work of the present utility model is as follows:
First assemble without bubble water sample acquisition device, water inlet pipe 4 with according to shown in 1 figure, insert bottle stopper 3, then fill in water sample chamber 1, then the valve 9 connecting on gas outlet 6 and exhaust hose with exhaust hose 8, finally rope is tied up in tether subring 10 and completes assembling.Open on water inlet pipe valve 7 on valve 5 and gas outlet, close the valve 9 on exhaust hose, with sling sampling apparatus put into water of rope, device overcomes the buoyancy in water and sinks under water by the weight of counterweight chamber 2, behind the sampling location of sinking to appointment until sampling apparatus, open the valve 9 on exhaust hose, water sample enters water sample chamber 1 along water inlet pipe 4, in water sample chamber 1, air is discharged in atmosphere along gas outlet 6, after water has been filled water sample chamber 1, pull-up rope hangs water body sampling apparatus, close on water inlet pipe valve 7 on valve 5 and gas outlet, the rope of finally taking off exhaust hose 8 and tether subring 10 completes sampling work.
