Description

A kind of deep water substrate sludge sampling device

Technical field

The present invention relates to a kind of sampling apparatus under water, specifically is a kind of sampling thief of deep water bed mud.

Background technology

In recent years along with economic, social development, the quickening of Development of China's Urbanization, shortage of water resources, water consumption increases, water quality function property shortage and cause reservoir to supply water to become the important water source that supports social development.Scientific research department and water resources management department more and more pay attention to the management of water resource quality, and this also requires scientific research department to accelerate development and renewal to all kinds of sample devicess.

Reservoir water body pollutes to be removed outside the upland water influence, and the very important pollution origin cause of formation is interacted, reacted and be discharged in the water body and cause by various poisonous and harmful substances in the mud of reservoir bottom of the reservior.The composition of detail knowledge bed mud is very important.The collection of bed mud whether complete is the important step of analyzing the bed mud constituent.

The bed mud of large reservoir (river course); Through depositing for many years, depositing; And the bottom sluggish flow, the water substitution time limit (cycle is longer), the pollutant component that brings of reservoir upland water is through be deposited on the reservoir bottom and cause the pollutant component of mud complicated year in year out in addition; Microorganism, physical change through long-term complicacy discharge, and have influence on whole reservoir water body quality.

Existing deep water (reservoir, large-scale river course) substrate sludge sampling method is to adopt sediment sampler (grappling fixture type, bar type are applicable to shallow water), utilizes deadweight to put into the bottom, grasps bed mud and comes sampling analysis.

Present stage, sediment sampler existed the inconvenience in many uses., in water process down, adopt the mud grab bucket and cause sampling process failure (grabbing) transferring to close too early before water-bed like sampling thief grab bucket less than bed mud; Grab bucket water is down grabbed later on before the mud, and grab bucket can not be closed smoothly and caused reasons such as grabbing the mud failure, causes and grabs mud inefficiency, time-consuming.

Summary of the invention

The object of the invention is to the problem that exists in the prior art a kind of deep water substrate sludge sampling device to be provided, and easy to use, can in following water process, not close because of grab bucket influences mud appearance collecting work, and simple in structure, and cost is low.

The technical scheme that adopts is:

A kind of deep water substrate sludge sampling device comprises grab bucket suspension hook and suspension hook supporting mechanism.

Grab bucket is made up of a left side half grab bucket and right half grab bucket, and connects into an one-piece construction through the grab bucket axle.

The suspension hook supporting mechanism comprises suspension hook support, left suspension bracket, right suspension bracket and cable wire.

Suspension hook is installed on the axle of suspension hook support, and there is the cable wire through hole upper end of suspension hook support.

Left side suspension bracket by upper left cross support arm, left front perpendicular pole and about perpendicular pole connect and compose; The two ends of upper left cross support arm are connected with first spring and second spring respectively, and the lower end of first spring and second spring is fixedly connected with the first left back bearing with the first left front bearing of partly grabbing bucket on the upper surface in a left side respectively; The lower end of left front perpendicular pole and left back perpendicular pole is hinged with partly grab bucket before second on upper surface left support abutment and the second back left support abutment of a left side respectively.

Right suspension bracket is connected and composed by upper right cross support arm, right front perpendicular pole and right back perpendicular pole; The two ends of upper right cross support arm are connected with the 3rd spring and the 4th spring respectively, and the lower end of the 3rd spring and the 4th spring is connected with the first right back bearing with the first right front bearing of partly grabbing bucket on the upper surface in the right side respectively; The lower end of right front perpendicular pole and right back perpendicular pole is hinged with the second right front bearing and the second right back bearing partly grabbed bucket on the upper surface in the right side respectively.

The suspension hook supporting mechanism is arranged on the top of grab bucket, the upper left cross support arm that the left side hook of suspension hook can hook left suspension bracket; The upper right cross support arm that the right side hook of suspension hook can hook right suspension bracket.

After cable wire passes the cable wire through hole of suspension hook support upper end, be fixedly connected with rear wall with the front side wall of partly grabbing bucket in a left side respectively behind the corresponding cable wire through hole on the front side wall that its two ends are passed cable wire through hole and right half grab bucket on the grab bucket axle two ends respectively and the rear wall.

To the deep water substrate sludge sampling time, the left side hook and the right upper right cross support arm of linking up with the upper left cross bar and the right suspension bracket that hook left suspension bracket respectively that let suspension hook.When a left side half grab bucket touched the deep water bed mud with right half grab bucket, suspension hook and left suspension bracket and right suspension bracket broke away from, simultaneously the suspension hook support by on carry, half grab bucket of a cable wire pulling left side begins to grab the mud sampling with right half grab bucket, and fastening, rises to the water surface by lifting means.

Advantage of the present invention:

1, the present invention can guarantee that grab bucket (critical piece of sediment sampler) can be in proper working order in following water process, can not close the mud process of adopting that influences in the water process down because of grab bucket.

2, the present invention is simple in structure, and parts are few, is easy to popularize.

3, the present invention uses simply, and volume is little, be easy to carry about with one.
