Abstract
一种浅滩型河流野外底泥采样器，包括能够伸缩的连杆，连杆的一端设置摇轮，另一端设置抓斗，摇轮与抓斗之间通过牵引绳进行连接，连杆在设置抓斗的一端安装有用于支承牵引绳的转向滑轮，通过摇轮对牵引绳进行收放，能够实现抓斗上下高度的调节。抓斗的内部安装锁止机构，抓斗初始状态下张开，伸入底泥后通过锁止机构动作使其闭合。本实用新型通过能够伸缩的连杆延长了抓斗下放的距离，通过摇轮对牵引绳进行收放，能够实现抓斗上下高度的调节，当没有船舶、桥梁、吊索等辅助的情况下也能够便捷地取到底泥样品。本实用新型结构简单，加工成本低廉，使用方便，无需工作人员涉水取样，应用前景较好。
A shoal-type river field sediment sampler comprises a telescopic connecting rod, one end of the connecting rod is provided with a rocking wheel, the other end is provided with a grab bucket, the rocking wheel and the grab bucket are connected by a traction rope, and the connecting rod is provided with a grabbing rope. One end of the bucket is installed with a steering pulley for supporting the traction rope, and the traction rope is retracted and released through the rocking wheel, so that the upper and lower heights of the grab bucket can be adjusted. A locking mechanism is installed inside the grab bucket. The grab bucket is opened in the initial state, and is closed by the action of the locking mechanism after extending into the bottom mud. The utility model prolongs the lowering distance of the grab bucket through the telescopic connecting rod, and retracts the traction rope through the rocking wheel, so that the upper and lower height of the grab bucket can be adjusted, and it can also be adjusted without the assistance of ships, bridges, slings, etc. The sediment samples can be easily taken. The utility model has the advantages of simple structure, low processing cost, convenient use, no need for staff to wading in water for sampling, and good application prospect.
Description
Technical field
The utility model belongs to field of environment engineering, and in particular to a kind of shoal type river field sediment sampler.
Background technique
Device requirement at present about field environment monitoring is increasing, especially field bed mud in river collector.Market
Upper existing field bed mud in river collector is mostly to need for great rivers either Hu Bo by means of ship, bridge, hoist cable
Deng progress.Sampler is mostly stainless steel material, and can pass through company when being promoted equipped with a grab bucket in sampler bottom bottom end
Grab bucket is automatically closed in connection device.But some small-sized shoal type rivers are directed to, it is assisted without ship, bridge, hoist cable etc., very
Difficulty gets the water sample at river center, and except non-working person paddles sampling, this is less feasible in cold season.
Utility model content
The purpose of this utility model is that being directed to above-mentioned the problems of the prior art, a kind of shoal type river field bottom is provided
Mud sampler, staff do not need to paddle when in use, can get the bed mud sample at river center on bank.
To achieve the goals above, the utility model includes the connecting rod that can be stretched, and rolled round is arranged in one end of connecting rod, another
End setting grab bucket, is attached between rolled round and grab bucket by traction rope, and connecting rod is equipped in one end of setting grab bucket for branch
The angle pulley for holding traction rope carries out folding and unfolding to traction rope by rolled round, can be realized the adjusting of grab bucket upper-lower height.
Grab bucket is internal to install lockable mechanism, opens under original state of grabbing bucket, and is made after protruding into bed mud by lockable mechanism movement
It is closed.
Lockable mechanism is made of spring and buckle, closure when can prevent grab bucket from declining, and triggers buckle after protruding into bed mud
Movement.
The grab bucket offers permeable mesh on the wall surface of top half.
The connecting rod is composed of by the way of plug connection several section support rods.
The grab bucket is made of stainless steel, opening area 230cm2, fording depth 60m.
The traction rope uses nylon rope.
Compared with prior art, the utility model is with following the utility model has the advantages that being extended by the connecting rod that can be stretched
The distance transferred of grabbing bucket can be realized the adjusting of grab bucket upper-lower height, for shoal type by rolled round to traction rope progress folding and unfolding
In bed mud in river sampling process, bed mud sample also can be easily got in the case where not having the auxiliary such as ship, bridge, hoist cable
Product.The utility model structure is simple, and low processing cost is easy to use, paddles sampling without staff, application prospect compared with
It is good.
Further, the utility model grab bucket offers permeable mesh on the wall surface of top half, when reducing decentralization
Resistance.
Detailed description of the invention
The structural schematic diagram of Fig. 1 the utility model；
In attached drawing: 1- rolled round；2- connecting rod；3- angle pulley；4- traction rope；5- grab bucket；6- lockable mechanism；7- permeable net
Eye.
Specific embodiment
The following describes the utility model in further detail with reference to the accompanying drawings.
Referring to Fig. 1, the utility model is directed to the design of shoal type river, includes the connecting rod 2 that can be stretched in structure, even
One end of bar 2 is arranged rolled round 1, other end setting grab bucket 5, grab bucket 5 inside installation lockable mechanism 6, grab bucket 5 original states lower
It opens, protruding into after bed mud makes its closure by the movement of lockable mechanism 6.Lockable mechanism 6 is made of spring and buckle, 5 decline of grab bucket
It can prevent from being closed in the process, trigger snap action after protruding into bed mud.Connected between rolled round 1 and grab bucket 5 by traction rope 4
It connects, grab bucket 5 offers permeable mesh 7 on the wall surface of top half.Connecting rod 2 is by several section support rods using the side of plug connection
Formula is composed, and connecting rod 2 is equipped with the angle pulley 3 for supporting traction rope 4 in one end of setting grab bucket 5, right by rolled round 1
Traction rope 4 carries out folding and unfolding, can be realized the adjusting of 5 upper-lower heights of grab bucket.Grab bucket 5 is made of stainless steel, weight 6.8kg,
Opening area is 230cm2, fording depth 60m, traction rope 4 is using nylon rope.
It grabs bucket the permeable mesh 7 opened up on 5 wall surfaces, the influence of rivers shock wave can be reduced, effectively prevent sample loss,
The grab bucket 5 of stainless steel material has been effectively ensured that bed mud sample is not contaminated, while also preventing corruption of the bed mud sample to sampler
Erosion.It, can be the case where no ship, bridge, hoist cable etc. assist by the utility model especially in northern cold winter
Under, bed mud sample can also be easily got, structure is simple, low processing cost, easy to use.
