Abstract
The invention discloses a dissolved oxygen water sampling device for surface water. The dissolved oxygen water sampling device comprises a water sampling bottle with a bottle plug, an accommodating body and a marking rod with a scale, wherein the accommodating body is provided with an accommodating cavity used for accommodating the water sampling bottle; the marking rod is fixedly connected with the accommodating body; a limiting piece used for limiting the entry and exiting of the water sampling bottle is also arranged on the accommodating body; a water inlet pipe and an air exhaust pipe communicated with the interior and the exterior of the water sampling bottle are arranged on the bottle plug; the lower end of the air exhaust pipe is flush with the lower surface of the bottle plug; in a matching state of the bottle plug and the water sampling bottle, the distance between the lower end of the water inlet pipe and the bottom of the water sampling bottle is 1mm to 2mm; the device also comprises a water inlet control plug with a pulling rope; the diameter of the water inlet control plug is matched with the pipe diameter of the water inlet pipe; the pulling rope is longer than the marking rod. The dissolved oxygen water sampling device for the surface water has the beneficial effects that the structure is simple, and the operation is convenient; in a water sampling process, water is injected from the bottom of the water sampling bottle until the water overflows from the top of the water sampling bottle, so that bubbles cannot exist in the water sampling bottle while the water sampling bottle is not aerated.
Description
Technical field
The present invention relates to hydrophore tool technical field, particularly a kind of surface water dissolved oxygen DO water sampling device.
Background technology
Measure Dissolved Oxygen in Surface Water, water sample needs to collect in dissolved oxygen DO sounding bottle.When gathering water sample, sounding bottle will go deep into the certain degree of depth of surface water to carry out adopting water, and to note especially not making water sample aeration or having bubble to exist in sounding bottle, whole adopt water process water sample all should from injecting water sample bottom dissolved oxygen DO sounding bottle to about 1/3 ~ 1/2 of overflow bottle outlet volume.
But adopt in water process at the surface water dissolved oxygen DO of reality, do not have exercisable employing utensil, operation is difficult to accurately control entering and overflow of water sample by hand.
Therefore prior art haves much room for improvement and develops.
Summary of the invention
The technical problem to be solved in the present invention is to provide one makes water sample inject until from top overflow bottom sounding bottle, make sounding bottle not aeration equally there is no the surface water dissolved oxygen DO water sampling device of bubble yet.
Technical solution of the present invention is: a kind of surface water dissolved oxygen DO water sampling device, comprises the sounding bottle of band bottle stopper, with the accommodating body of the accommodating cavity for placing sounding bottle and the flag-rod of scale with a scale that is fixedly connected with this accommodating body; This accommodating body is also provided with the locating part for limiting the turnover of this sounding bottle; This bottle stopper is provided with and is communicated with the inner and extraneous water inlet pipe of sounding bottle and gas outlet; Gas outlet lower end is concordant with bottle stopper lower surface; In bottle stopper and sounding bottle mated condition, the distance bottom the distance sounding bottle of water inlet pipe lower end is 1 ~ 2mm; The water inlet also comprising the band traction rope suitable with water inlet pipe caliber controls to fill in, the length of the length greater than flag bar of this traction rope.
Described locating part is inverted U-shaped, and can horizontally rotate.When locating part is connected across accommodating body opening, then limits sounding bottle and take out.
Beneficial effect of the present invention:
Structure is simple, easy to operate, adopts water process water and injects until from top overflow bottom sounding bottle, make sounding bottle not aeration equally do not have in bubble sounding bottle yet.
Accompanying drawing explanation
Fig. 1 is cut-open view of the present invention;
Fig. 2 is perspective view of the present invention.
Embodiment
Embodiment:
Consulting Fig. 1, Fig. 2, a kind of surface water dissolved oxygen DO water sampling device, comprising the sounding bottle 2 of band bottle stopper 1, with the accommodating body 3 of the accommodating cavity for placing sounding bottle 2 and the flag-rod 4 of scale with a scale that is fixedly connected with this accommodating body 3; This accommodating body 3 is also provided with the locating part 31 for limiting the turnover of this sounding bottle 2; This bottle stopper 1 is provided with and is communicated with inner with the extraneous water inlet pipe of sounding bottle 2 11 and gas outlet 12; Gas outlet 12 lower end is concordant with bottle stopper 1 lower surface; In bottle stopper 1 and sounding bottle 2 mated condition, the distance bottom the distance sounding bottle 2 of water inlet pipe 11 lower end is 1 ~ 2mm, is preferably 2mm; The water inlet also comprising the band traction rope 6 suitable with water inlet pipe 11 caliber controls plug 5, the length of the length greater than flag bar 4 of this traction rope 6.
Described locating part 31 in inverted U-shaped, and can horizontally rotate.When locating part 31 is connected across accommodating body opening, then limits sounding bottle 2 and take out.
This accommodating body 3 is made up of metal stainless steel, and bottle stopper 1 is rubber plug, and water inlet pipe 11 and gas outlet internal diameter are the glass tubule of 3mm, and water inlet pipe 11 is different with the length of gas outlet 12, and water inlet pipe 11 top is 30mm place outside bottle stopper 1 top; Gas outlet 12 top is 150mm place outside bottle stopper 1 top.
Concrete use procedure of the present invention:
1) open the locating part of the sounding bottle turnover that accommodating body can limit, sounding bottle is put into;
2) locating part of the sounding bottle turnover that accommodating body can limit is closed, by bottle stopper in sounding bottle
3) on the cover of water inlet pipe top, water inlet controls plug;
4) put into this device in dissolved oxygen DO sampling waters, control by flag-rod the employing degree of depth reaching correlation standard;
5) pull the traction rope controlling to fill in into water to open and control plug into water, water sample is injected after bottom sounding bottle by water inlet pipe and diffuses in sounding bottle top, ensures wholely to adopt water process all and bottom dissolved oxygen DO sounding bottle, inject water sample do not make water sample aeration or have bubble to there is sampling bottle.
