Description

Hand scene water sample Duplicate Samples sampler

Technical field

A kind of sampling tool of environmental monitoring is the utility model is related to, particularly a kind of water sample Duplicate Samples sampler.

Background technology

Live Duplicate Samples refer under identical sampling condition, gather parallel double sample passwords and send lab analysis, measurement result Sampling and experimental determination precision can be reflected.Live Duplicate Samples are it is noted that control sampling operation is consistent with condition.

Existing live water sample Duplicate Samples sampling, some is limited by condition, is to use simple and easy method, such as adopted with well-bucket Collect the water sample of certain volume, scene is scooped by water is divided in water sample in sampling bottle.This simple and easy method can not be accomplished to put down completely OK, and waste time and energy, water sample easily scoops pollution by water, it is impossible to meet live Duplicate Samples sampling request.

Utility model content

Purpose of utility model：In view of the above-mentioned problems, the purpose of this utility model, which is to provide one kind, meets that live Duplicate Samples are adopted The water sampling device of sample requirement, improve the accuracy of Duplicate Samples.

Technical scheme：A kind of hand scene water sample Duplicate Samples sampler, including closed staving, sampling pipe, the bucket Body is internally provided with piston, lifting handle is provided with outside the staving, the lifting handle is connected with the piston, described to adopt Sample pipe is outside the staving, and the sampling pipe includes water inlet pipe, two distributive pipes, and described water inlet pipe one end is under the staving It is square that the water inlet pipe other end is water inlet, and described distributive pipe one end connects with the water inlet pipe with being connected inside the staving, The distributive pipe other end is delivery port, and check valve is respectively arranged with the water inlet pipe, distributive pipe, and the check valve is arranged at Before the water inlet pipe, distributive pipe connectivity part.

Optimal, in addition to spring, fixed support outside the staving are arranged on, the fixed support carries positioned at described Rise above handle and fixed with the staving, the spring is connected between the fixed support and the lifting handle.Lifting Handle can push automatically under the action of the spring, piston is moved down reset.

Optimal, the piston outer is provided with sealing ring, and the sealing ring is bonded with the inner wall of barrel.

Beneficial effect：Compared with prior art, the utility model has the advantages that preferably resolving the scene of water sample sampling Duplicate Samples accuracy problem, sampler structure is reliable, durable, easy to operate, time saving and energy saving, before being provided to subsequent measurements result Propose guarantee.

Embodiment

Below in conjunction with the accompanying drawings and specific embodiment, the utility model is furtherd elucidate, it should be understood that these embodiments are only used for Illustrate the utility model rather than limitation the scope of the utility model, after the utility model has been read, art technology Modification of the personnel to the various equivalent form of values of the present utility model falls within the application appended claims limited range.

A kind of hand scene water sample Duplicate Samples sampler, as shown in accompanying drawing 1-4, including closed staving 1, sampling pipe 2, Lifting handle 4, spring 5, fixed support 6.

Staving 1 is internally provided with piston 3, and the outer of piston 3 is provided with sealing ring 31, and sealing ring 31 is bonded with the inwall of staving 1. Lifting handle 4 is arranged in barrel wall outside staving 1 and is connected with piston 3, and spring 5, fixed support 6 are outside staving 1, fixed support 6 are fixed above lifting handle 4 and with staving 1, and spring 5 is connected between fixed support 6 and lifting handle 4.

Sampling pipe 2 is outside staving 1, including 21, two distributive pipes 22 of water inlet pipe, and the one end of water inlet pipe 21 is below staving 1 It is arranged in barrel wall to connect with the inside of staving 1, the other end of water inlet pipe 21 is water inlet 23, and the one end of distributive pipe 22 connects with water inlet pipe 21 Logical, the other end of distributive pipe 22 is delivery port 24, is respectively arranged with check valve 25 in water inlet pipe 21, distributive pipe 22, check valve 25 is set Before being placed in water inlet pipe 21, the connectivity part of distributive pipe 22.

Application method and operation principle of the present utility model are：It will be immersed first below sampler in waters to be sampled, leaching No sampling pipe, then manually operated to pull up lifting handle, then piston, which moves up, produces suction negative pressure, due to the work of check valve With now check valve is opened in water inlet pipe, and water sample flows into water inlet pipe, and closed check valve in distributive pipe, water sample by water inlet Continue to flow into staving internal piston lower chamber and store；After the completion of water acquisition, sampler is taken out from waters to be sampled, manually Lifting handle is pressed downward, or loosing one's grip makes lifting handle be pressed downward under the action of the spring, then piston moves down, now unidirectional in water inlet pipe Valve is closed, and check valve is opened in distributive pipe, and the water sample of staving internal piston lower chamber storage is by quickly and evenly one point Two discharge from the delivery port of two distributive pipes, complete the sampling of live Duplicate Samples.And so on, live Duplicate Samples sampling is completed.
