Description
Technical field
The invention belongs to monitoring water environment sampling equipment technical field, particularly to a kind of ball-valve type alluvial earth undisturbed soil sample sampler, further relate to use the sampling method of this sampler.
Background technology
The amount of sludge that river, lake, urban look area deposit is huge, and riverway sludge not only reduces the mobility of water, causes the self-purification capacity of water body to decline, and even can become the presence of pollution sources in river course, and therefore monitoring water environment and channel cleanout work are the most particularly important.Riverway sludge is different from general clay, it is rich in polluter and nutrient substance, for determining that concrete which kind of methods of employing carry out channel cleanout work, its component content need to be furtherd investigate for different mud, analyze its feature, and obtaining the representativeness of mud sample, scientific most important, the riverway sludge sample that this will ask for is as far as possible for undisturbed soil sample.
Mud is become to be grouped into by clay, sand, Organic substance etc., has a series of special character, and its obvious characteristic is high-moisture, and common soil sampler easily causes soil sample and runs off, and sampling difficulty is big, but its water content is high just so that it is have the advantage being prone to incision.Owing to being intercepted by the depth of water, riverway sludge sample can not directly use container to contain and take, and existing soil sample collector is unsuitable for going deep into being sampled in water, or after going deep in water, caused soil sample disturbance by water currents.
The original state sampling device depth selection being applicable to river or lake at present is limited, and generally requires and set up carrying platform or carry ship rig, and equipment is installed mobile the most inconvenient, relatively costly.Further, since mud is in liquid-plastic state mostly, existing sampler is poor due to closing in sealing, easily causes sample and runs off, affect data results in sampler lifting process.
Summary of the invention
Present invention seek to address that the technical problems such as existing alluvial earth sampler depth selection is limited, structure is complicated, complex operation, sample are easy to run off, provide a kind of ball-valve type alluvial earth undisturbed soil sample sampler, and the practical approach of this sampler is illustrated.The present invention makes the mud sample of acquirement can keep original character, it is ensured that when sampler leaves water-soil environment, and mud sample does not runs off and keeps its natural moisture content, have simultaneously easy to carry, dismount simple advantage.
To achieve these goals, the present invention takes following technical scheme:

Detailed description of the invention
Now will the present invention be elaborated further, in order to understand the purpose of the present invention, technical scheme and effect thereof in conjunction with the embodiments.
This gives a kind of ball-valve type alluvial earth undisturbed soil sample sampler (hereinafter referred to as sampler), as it is shown in figure 1, include handle 1, rotary shaft 2, counterweight plummer 4, shoe 8, folding blade 7, closure plate 9 and at least extension rod 3.Described handle 1 is flexibly connected with the upper end of rotary shaft 2, and handle 1 can rotate around rotary shaft 2 so that handle 1 is parallel to the ground or vertical.The lower end of rotary shaft 2 is connected with the threaded upper ends of extension rod 3, the lower end threaded counterweight plummer 4 of extension rod 3.Therefore, the length of the sampler of the present embodiment can regulate, the number of required extension rod 3 is selected according to different river levels or the lake depth of water, between each extension rod 3 threaded, facilitate between extension rod 3, dismounting between rotary shaft 2 and extension rod 3, between extension rod 3 and counterweight plummer 4, it is simple to carry and transport.
The shoe 8 accommodating mud sample it is welded with in the lower section of counterweight plummer 4.Described shoe 8 is the circular cylindrical cavity structure of hollow, and the upper end within shoe 8 is provided with ball valve 6, ball valve 6 be arranged above the multiple and extraneous water stream channel 5 being connected, the lower end within shoe 8 arranges folding blade 7.It should be noted that folding blade 7 is six flap-type, every lobe folding blade all offers multiple micro through-hole, is discharged from by water after being used for promoting sampler.The lower port of shoe 8 connects closure plate 9 by an active connection, and the lower port of shoe 8 can select gemel connection closure plate 9, and closure plate 9 just can rotate around the lower port of shoe 8.Offering a through hole at the edge of closure plate 9 and the position relative with active connection, through hole hitches one end of pull rope 10, the upper weld one pull rope snap ring 11 outside shoe 8, and the free end of pull rope 10 passes pull rope snap ring 11.Free end by Traction rope 10, it is achieved closure plate 9 closes the lower port of shoe 8, is saved in shoe 8 internal by the mud sample of collection.
The sampler of the present embodiment also includes multiple balancing weight 12, as shown in Figure 2, described balancing weight 12 is hollow cylindrical structure part, balancing weight can be socketed on extension rod 3 by handle 1, groove is offered in the bottom of balancing weight 12, the horizontal center line of groove is by the center of circle of place circle bottom balancing weight 12, and on balancing weight 12, symmetry offers two vertical through holes, and described through hole is opened in the surface of groove.According to water velocity and buoyancy, select to lay the number of balancing weight 12 on counterweight plummer 5.Balancing weight 12 is socketed on extension rod 3 successively, and is deposited in the top of counterweight plummer 5.Especially, before socket balancing weight 12, use pull rope 10 along the groove of balancing weight 12 through balancing weight 12 both sides symmetry through hole, in order to scene needs to reduce the quantity of balancing weight 12, then can move and take off balancing weight 12 by Traction rope 10.
The method using the sampler of the present embodiment to carry out mud sampling, comprises the steps:
Step one, the degree of depth according to lake or river determines joint number and the number of balancing weight 12 of extension rod 3, by the free end of pull rope 10 along the groove of balancing weight 12 through the symmetrical through hole of balancing weight 12, rotary handle 1 is to perpendicular to the ground, being socketed on extension rod 3 by handle 1 by required balancing weight 12, rotary handle 1 is to parallel to the ground；
Step 2, puts in water by mounted sampler, keeps water stream channel 5 unimpeded, and shoe 8 inserts sampling in alluvial dirt bed.In sampler decentralization process, hydro-flow thrust makes folding blade 7 open, and ball valve 6 keeps unimpeded, and water is discharged along water stream channel 5；
Step 3, Traction rope 10 so that closure plate 9 closes the lower port of shoe 8.Promoting sampler, under the common effect that hydraulic pressure and mud are conducted oneself with dignity, folding blade 7 and ball valve 6 are closed, and the Free water of mud sample is discharged by the micropore on folding blade 7；
Step 4, uses pull rope 10 to unload balancing weight 12 successively, is left the water by sampler, takes out alluvial earth sample.
Above in conjunction with embodiment, the present invention done further narration, but the present invention has been not limited to above-mentioned embodiment, in the ken that one skilled in the relevant art is possessed, it is also possible to make a variety of changes on the premise of without departing from present inventive concept.
