Abstract
The utility model provides an undisturbed columnar bottom sludge sampler, which consists of a lifting rod, a sealing member, a fastening member and a sampling pipe. The lower end of the lifting rod is connected with the upper end of the fastening member; the upper end of the sampling pipe is inserted in the fastening member; the sealing member is placed in the fastening member. The bottom sludge sampler can cause collecting personnel to finish the process of collecting bottom sludge samples when standing on the bank or on a boat without diving into water, thus being time-saving and labor-saving; in addition, during the collecting process, bottom sludge is undisturbed; polluted bottom sludge samples in separated layers of different depths can be collected; samples collected can truly reflect the pollution status of the bottom sludge.
Description
Technical field
The utility model relates in a kind of environment measuring process gathers the sampling thief that river, lake, reservoir etc. are located polluted bed mud, belongs to the sediment sampler technical field.
Background technology
In the serious river of endogenous pollution, lake, reservoir pollution governance process, at first need to understand the pollutant load and the pollutant release strength thereof of different depth polluted bed mud, could scientificlly and effectively determine dredging depth.At present, the sample collecting of lake, reservoir pollution substrate mainly adopts the grab bucket bottom sampler, gathers the top layer polluted bed mud, can't obtain the polluted bed mud sample of different depth layering.For obtaining the bed mud sample of different depth layering, need manually dive beneath the water and carry out sample collecting, not only waste time and energy, and also easy disturbance bed mud, the disturbed specimen collection.
Summary of the invention
The utility model provides a kind of no disturbance column sediment sampler that obtains the layering polluted bed mud sample of different depth, can not produce disturbance to bed mud at the problem that existing lake, the bottom mud column-shaped sample collecting technology of reservoir exist.
The utility model is realized by following technical scheme:
No disturbance column sediment sampler is made up of elevating lever, seal, securing member, sampling pipe, and the lower end of elevating lever is connected with the upper end of securing member, and the upper end of sampling pipe is inserted in the securing member, and seal is placed in the securing member.
Elevating lever is formed by connecting by pipe adapter by the quarter butt more than two, can regulate the length of elevating lever according to water depth.
Securing member is made up of at least three screw rods, cover plate, silica gel circle, supporting disk and gland, the upper end of every screw rod all connects on the cover board, the middle part is fixed with supporting disk, is connected with gland on the every screw rod below supporting disk, is provided with the silica gel circle between supporting disk and the gland.Seal is placed between cover plate and the supporting disk.
Sampling pipe is a plexi-glass tubular, and its length is determined according to the degree of depth of collected specimens.
In the sampling process, according to the length of the depth adjustment elevating lever of water body, sampling pipe frictionally and securing member are connected firmly.The sample collector stands aboard ship or the bank, holds elevating lever, and behind the sampling depth that the sampling pipe insertion is suitable, the cylindrical sample of required sampling depth will enter in the sampling pipe.Upwards lift elevating lever, when the water surface is shifted out in the lower end of sampling pipe, seal its lower end with the rubber plug fast, finish bottom mud column-shaped sample collecting process.
Sediment sampler of the present utility model can make the collection personnel stand in and finish bed mud sample collecting process on bank or the ship, need not to pull the plug, time saving and energy saving, and not disturbance bed mud in the gatherer process, can obtain the layering polluted bed mud sample of different depth, collected specimens can truly reflect the sediment pollution situation.
Description of drawings:
Accompanying drawing is a column sediment sampler structural representation of the present utility model.
Among the figure: 1, elevating lever, 2, seal, 3, sampling pipe, 4, pipe adapter, 5, screw rod, 6, cover plate, 7, the silica gel circle, 8, supporting disk, 9, gland, 10, nut.
Embodiment
As shown in Figure 1, column sediment sampler of the present utility model is made up of elevating lever 1, seal 2, securing member and sampling pipe 3.Elevating lever 1 is formed by connecting by pipe adapter 4 by the stainless-steel tube of some both end threads, can regulate the length of elevating lever according to water depth, guarantees that sampling pipe 3 enters suitable sampling depth.The cover plate 6 of the lower end of elevating lever 1 and securing member upper end is to be threaded.
Securing member is made up of four screw rods 5, cover plate 6, silica gel circle 7, supporting disk 8 and gland 9, and cover plate 6, supporting disk 8, gland 9 and screw rod 5 are stainless steel.The upper end of four screw rods 5 all is connected on the cover plate 6 by nut, and the middle part of four screw rods is fixed with supporting disk 8, is connected with gland 9 at the nut 10 below by on four screw rods of supporting disk 8, is provided with silica gel circle 7 between supporting disk and the gland.Insert in the silica gel circle 7 upper end of sampling pipe 3, and the friction force between dependence and the silica gel circle 7 interconnects.Sampling pipe 3 tightens the nut 10 on the screw rod 5 after inserting silica gel circles 7, makes supporting disk 8 and gland 9 extruding silica gel circles 7, and silica gel circle 7 by compression expands to the inside, has increased the friction force with sampling pipe 3, and sampling pipe can landing in the assurance sampling process.Sampling is transferred loose supporting disk 8 and gland 9 after finishing, and 7 withdrawals of silica gel circle are restored, and the friction force between sampling pipe 3 and the silica gel circle 7 reduces, and sampling pipe 3 can take out in silica gel circle 7 like a cork.
In the sampling process,, sampling pipe 3 is inserted in the securing members 2 according to the length of the depth adjustment elevating lever 1 of water body, by tightening supporting disk 8 and gland 9 extruding silica gel circles 7, silica gel circle 7 expands by compression to the inside, and sampling pipe 3 is clamped firmly, avoids sampling pipe landing in the sampling process.The sample collector stands aboard ship or the bank, holds elevating lever 1, moves down sampling pipe 3, in this process, has the gap between seal 2 and the supporting disk 8, and behind the sampling depth that sampling pipe 3 insertions are suitable, the cylindrical sample of required sampling depth will enter in the sampling pipe 3.Manually upwards lift elevating lever, rely on the differential water pressures of the upper and lower layer of water body, seal 2 is combined closely with supporting disk 8, and the cylindrical sample of collection is sealed in the sampling pipe 3.When the water surface is shifted out in the lower end of sampling pipe 3, seal its lower end with the rubber plug fast, transfer the bolt 5 on the degree of tightness firmware, friction force reduces between silica gel circle 7 and the sampling pipe 3, can take out sampling pipe 3, finishes bottom mud column-shaped sample collecting process.
