Abstract
The utility model provides a portable columnar sampling device for bottom mud in a lake or a river. The bottom mud in the lake or the river is an important content in water environment protection and scientific research. The collection of bottom mud samples is the premise of the bottom mud research work. At present, a bottom mud sampling device is mainly a digging-type sampling device at home and abroad. The digging-type sampling device is poor in enclosed sealing performance, and large in disturbance to samples, and can only collect surface bottom mud samples. The portable columnar sampling device comprises a sampling pipe (1), wherein the upper end of the sampling pipe is inserted in a silicon ring (2) which is arranged between a support disc (3) and a pressing cover (4). A cover plate (6) is fixedly arranged on the support disc through screw rods (5). The screw rods penetrate through the cover plate and the support disc and the cover plate in sequence, and a lifting rod (7) penetrates through the cover plate, and is connected with a sealing piece (8). The portable columnar sampling device is used for collecting the bottom mud in the lake or the river.
Description
Technical field:
The utility model relates to a kind of lake or river portable column substrate sludge sampling device.
Background technology:
Lake, bed mud in river are the important contents of water environment protection and scientific research, the collection of bed mud sample is the prerequisite of bed mud research work, present substrate sludge sampling device both domestic and external mainly contains grab bucket bottom sampler and pick formula sampling apparatus, the grab bucket bottom sampler can only gather sediments, for obtaining the bed mud sample of different depth layering, need to manually dive beneath the water and carry out sample collection, not only waste time and energy, and easy disturbance bed mud, disturb product collection; Pick formula sampling apparatus closing seam in sampling process is poor, large to the disturbance of sample, can only gather the sediments sample.
Summary of the invention:
The purpose of this utility model provides a kind of lake or river portable column substrate sludge sampling device, can obtain the bed mud sample of different depth layering.
Above-mentioned purpose realizes by following technical scheme:
A kind of lake or river portable column substrate sludge sampling device, its composition comprises: sampling pipe, the upper end of described sampling pipe is inserted in the silica gel ring, described silica gel ring is installed between supporting disk and the gland, described supporting disk top is installed with cover plate by screw rod, described screw rod passes described cover plate, described supporting disk, described cover plate successively, and elevating lever passes described cover plate, and described elevating lever is connected with seal.
Described lake or river portable column substrate sludge sampling device, described sampling pipe is plexi-glass tubular.
Described lake or river portable column substrate sludge sampling device, described elevating lever is connected to form by short circuit head by the quarter butt more than two.
Beneficial effect:
The utility model need not to pull the plug, and is time saving and energy saving, and not disturbance bed mud in the gatherer process, can obtain the layering mud bed mud sample of different depth, and collected specimens can truly reflect the bed mud situation.
Description of drawings:
Accompanying drawing 1 is the structural representation of this product.
Accompanying drawing 2 is vertical views of accompanying drawing 1.
Embodiment:
Embodiment 1:
A kind of lake or river portable column substrate sludge sampling device, its composition comprises: sampling pipe 1, it is characterized in that: the upper end of described sampling pipe is inserted in the silica gel ring 2, described silica gel ring is installed between supporting disk 3 and the gland 4, described supporting disk top is installed with cover plate 6 by screw rod 5, described screw rod passes described cover plate, described supporting disk, described cover plate successively, and elevating lever 7 passes described cover plate, and described elevating lever is connected with seal 8.
Embodiment 2:
Above-mentioned lake or river portable column substrate sludge sampling device, described sampling pipe is plexi-glass tubular, its length is determined according to the degree of depth of collected specimens.
Above-mentioned lake or river portable column substrate sludge sampling device, described elevating lever is connected to form by short circuit head 9 by the quarter butt more than two, can regulate the length of elevating lever according to water depth, guarantees that sampling pipe enters suitable sampling depth.
Above-mentioned lake or river portable column substrate sludge sampling device, be positioned at above the described cover plate and on the screw rod below the described gland nut 10 is installed, insert in the silica gel ring upper end of sampling pipe, friction force extruding silica gel ring between dependence and the silica gel ring, silica gel ring by compression is inboard to expand, increased the friction force with sampling pipe, guaranteed that the sampling pipe in the sampling process can landing.
Embodiment 3:
Above-mentioned lake or river portable column substrate sludge sampling device, in the sampling process, the sample collector holds elevating lever, move down sampling pipe, at this moment, there is the gap between seal and the supporting disk, behind the sampling depth that the sampling pipe insertion is suitable, the cylindrical sample of required sampling depth will enter in the sampling pipe, manually upwards lifts elevating lever, relies on the water body, the differential water pressures of lower floor, seal and supporting disk are combined closely, the cylindrical sample that gathers is sealed in the sampling pipe, when the water surface is shifted out in the lower end of sampling pipe, seals its lower end with the rubber plug fast, transfer the nut on the degree of tightness firmware, friction force reduces between silica gel ring and the collection tube, can take out sampling pipe, finishes bottom mud column-shaped sample collection process.
Claims (3)
1. lake or river portable column substrate sludge sampling device, its composition comprises: sampling pipe, it is characterized in that: the upper end of described sampling pipe is inserted in the silica gel ring, described silica gel ring is installed between supporting disk and the gland, described supporting disk top is installed with cover plate by screw rod, described screw rod passes described cover plate, described supporting disk, described cover plate successively, and elevating lever passes described cover plate, and described elevating lever is connected with seal.
2. the portable column substrate sludge sampling in lake according to claim 1 or river device, it is characterized in that: described sampling pipe is plexi-glass tubular.
