Abstract
The utility model discloses a portable deepwater substrate sludge sampling device comprising a connection component, a sampling tube and a weight dropper, wherein the connection component comprises a connecting rod and a transition cavity which are connected by bolts; a one-way valve is arranged in the transition cavity, and the lower end of the transition cavity is connected with a counterweight device; the upper end of the sampling tube is positioned in the cavity and fixedly sealed by an O-shaped ring, and the lower end is sealed by opening or closing a blocking ball. Because of adopting the counterweight device, the device can run downwards in the state of a free falling body to sample the substrate sludge conveniently in the deep water, and consequently the utility model can keep the watercourse fluent, avoid disturbing the substrate sludge sample and keep the received sample intact. The sampling device is effective to sample the substrate sludge in lakes and rivers and is suitable for various environmental scientific research monitoring departments.
Description
Technical field
The utility model relates to a kind of lake of environmental protection, scientific research field, device of river substrate cylindrical sample sampling of being applicable to, relates in particular to a kind of portable deep water substrate sludge sampling device.
Background technology
Lake, bed mud in river are the important contents of water environment protection and scientific research, and the bed mud sample collecting is the prerequisite of bed mud research work, and present substrate sludge sampling device both domestic and external mainly contains pick formula sampling apparatus and pillar sampling apparatus two classes.Pick formula substrate sludge sampling device is the most frequently used in China lake, the bed mud in river research, and it is simple in structure, easy to operate, but such sampling apparatus closing seam in sampling process is poor, big to the disturbance of sample, can only gather top layer bed mud sample.Column substrate sludge sampling device increases the weight of device by weight etc., drives sampling pipe puncture bed mud, can gather the undisturbed bottom mud column-shaped sample of original state of certain depth.Such sampling apparatus installs complexity usually, needs the electronic or hand winch of adapted, and inconvenient operation requires high to sampling conditions such as sampling boats.During particularly to big depth of water lake or reservoir sampling, work difficulty is bigger.In addition, column-shaped sampling apparatus needs the sampling pipe bottom to insert bed mud, and comparatively difficulty of lower end closed mechanism is set, and the bed mud water percentage enters the easy slippage of bed mud post core of sampling pipe when high.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, provide a kind of and be easy to carry, but the one man operation is easy to dismounting, can make things convenient for the portable deep water substrate sludge sampling device of field work.
The technical solution adopted in the utility model is: a kind of portable deep water substrate sludge sampling device, include connecting elements, stopple coupon and weight, connecting elements is by comprising connecting rod and excessive cavity, connecting rod is connected by bolt with excessive cavity, excessively be provided with retaining valve in the cavity, excessively the cavity lower end connects counter weight device, and described stopple coupon upper end is arranged in cavity and by O type circle fixing seal, sealing is realized by the keying of stopping up ball in the stopple coupon lower end.
Further, be provided with hitch frame in the described connecting rod and be connected nylon rope with traction weight hitch frame upper end.
Further, be provided with the restriction rope under the described obstruction ball, the two ends of described obstruction ball are provided with stretch cord.
Adopt the technical solution of the utility model, owing to adopted counter weight device, this device can be descending with free falling body state, is convenient to deep water sampling; Owing to excessively be provided with retaining valve in the cavity, can guarantee that water channel is unimpeded, avoid disturbance bed mud sample; Because of being provided with effective closing device, complete to guarantee the sample that reclaims.
Description of drawings
Fig. 1 shows the structural representation of an embodiment of the present utility model.
Embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
As shown in Figure 1, the sampler of the utility model portable deep water substrate sludge sampling device comprises connecting rod 1 and excessive cavity, last connecting rod 1 is a hollow aluminium alloy pipe, the inside of last connecting rod 1 is provided with hanger bracket 13 and weight 12, hanger bracket 13 can freely glide under the effect of weight 12, the hanger bracket upper end is provided with nylon rope, hanger bracket 13 is provided with the taper pin nail, excessively cavity is by upper flange 2, cavity 3 is formed with lower flange 4, this three part connects by bolt, last connecting rod 1 and upper flange 2 are by being threaded, be provided with retaining valve 11 in the cavity 3, be provided with the O RunddichtringO between cavity 3 and the lower flange 4, stopple coupon 5 inserts in the cavity 3, and the deflection that relies on the O RunddichtringO to provide is fixed and sealed, the lower end of stopple coupon 5 is by stopping up ball 9 sealings, be connected with restriction rope 10 under the obstruction ball 9, the two ends of stopping up ball are connected with stretch cord 8, and stopple coupon 5 can adopt plexi-glass tubular.The lower end of lower flange 4 is connected with counter weight device, and counter weight device is made up of balance weight body 7 and counterweight connecting rod 6.
The principle of work and the method for operating of this device are as follows:
This sampler is to insert in the bottom mud in lake by deadweight.Sampler is in water body sinking process, and the current that gush in the stopple coupon 5 are washed retaining valve 11 open, to keep stopple coupon a unobstructed water channel are arranged.After sampler inserted sediment layer, retaining valve 11 fell after rise under action of gravity, by heavy water pressure seal stopple coupon 5 upper ends.Simultaneously, nylon rope is lax, hangs each parts concerted action of sealing mechanism, sealing stopple coupon 5 lower ends.
After sampler assembled, with being connected nylon rope on the hanger bracket sampler of slinging, hanger bracket 13 was drawn to upper limit position, and the taper pin nail on it skids off fluting;
Firmly 10 tensions of restriction rope, and hang over taper pin and nail on, restriction rope 10 is pulled away from stopple coupon 5 bottoms stopping up balls 9; Sampler is put into water, holds down at nylon rope outstanding, and is descending with nearly free falling body state, retaining valve 11 effects, the sampler water channel that keeps clear.After sampler inserts sediment layer, hang the sealing mechanism action, sealing stopple coupon upper/lower terminal;
Work the sampling device of choosing, finish sampling work.
The utility model is a kind of light portable, simple to operate, the substrate sludge sampling device satisfactory for result of taking a sample.Can on any depth of water lake, river, conveniently gather the bed mud sample that maintains the original state.
