Technical Field

The utility model relates to a sampling device, especially a tidal flat tidal water sample fixed point is gathered and tidal height monitoring devices.

Background

China is a large ocean country, estuaries and lakes are distributed in a large number, underwater sandbars and mudflats formed by scouring and accumulating silt carried by a plurality of rivers into the sea are also distributed widely, a large number of saline plants grow on a wide intertidal zone area and play an important role in protecting the wetland of China, but in recent years, a plurality of saline plants in the intertidal zone have serious degradation phenomena, and basic data such as salinity, silt concentration, tide, pollutant content and the like are fundamental clues and bases for the degradation research of the saline plants through the related analysis and research of scholars of China in recent years.

It also has important indicative function to gather intertidal zone sea water and carry out relevant index analysis and carry out coastal ecological remediation to the saline and alkaline type plant growing environment of simulation on this region, nevertheless because intertidal zone sand dam comprises silt material etc. and china lacks the basis of intertidal zone instrument sampling in addition, often still need gather the water sample of specific depth of water department when gathering the water sample simultaneously, it is dangerous just to adopt traditional artifical sampling mode to gather the water sample like this, and it is more consuming time hard to gather the water sample, it becomes difficult point to gather intertidal zone water sample and carry out relevant index analysis.

Detailed Description

The following description will explain embodiments of the present invention with reference to the drawings. As shown in fig. 1 and 2: a tidal flat tidal water sample fixed-point acquisition and tidal height monitoring device comprises a tripod 1, wherein a fixing column 2 is arranged at the center of the tripod 1, the bottom end of the fixing column 2 is a conical part 3, a plurality of buckles 4 with circular cross sections are equidistantly distributed on the fixing column 2, the top of each buckle 4 is a plane, the bottom of each buckle 4 is an arc surface, a floating ring 5 is further sleeved on the fixing column 2, the diameter of each floating ring 5 is 1.1 times that of each buckle 4, a limiting sheet 6 is arranged at the bottom of the fixing column 2, the diameter of each limiting sheet 6 is larger than that of each floating ring 5,

The utility model discloses tidal flat tidal water sample fixed point collection and tidal height monitoring devices's working process as follows: firstly, erecting a tripod 1 at a sampling point needing sampling during the ebb tide, and inserting a conical part 3 at the bottom end of a fixation column 2 into sludge to complete the erection of the device;

the floating ring 5 rises along with the rise of the seawater, when the floating ring 5 is in contact with the arc surface at the bottom of a certain buckle 4, the floating ring 5 and the fixing column 2 tend to be concentric under the guiding action of the arc surface, because the diameter of the floating ring 5 is 1.1 times (slightly larger) that of the buckle 4, when the water level exceeds the height of the certain buckle 4, the floating ring 5 can cross the buckle 4 and rise, and when the tide falls back, because the diameter of the floating ring 5 is only slightly larger than that of the buckle 4, and simultaneously the weight of the floating ring 5 is relatively lighter, the floating ring 5 can be clamped on the buckle 4 below the floating ring, therefore, after the device is recovered, a worker can judge the height of the tide by observing the position of the floating ring 5;

in actual use, scale marks can be marked on the surface of the fixation column 2, so that the rising height of the tidal water can be accurately judged by workers;

all the sealing door bodies 8 are in a closed state in an initial state, and the sampling chamber is isolated from external seawater at the moment; in the rising tide process, when the water level reaches the height of the liquid level sensor, the liquid level sensor can want the control module to send a signal, the control module controls all the electromagnetic valves 10 to be opened, seawater can flow into the corresponding sampling chambers through the through holes, when the height of the water body is higher than the height of the bottle openings of the sampling bottles 9, the seawater can flow into the sampling bottles 9, therefore, the floating sealing covers 11 in the sampling bottles 9 can rise along with the rise of the water level under the action of buoyancy, when the floating sealing covers 11 reach a certain height, the magnetic rings are in contact with the iron rings and attract each other, the floating sealing covers 11 can seal the sampling bottles 9 from the inside, and at the moment, the collected seawater samples are obtained in the sampling bottles 9;

because different sampling bottles 9 are distributed at different heights, the device can collect water samples in different depths at one time, and is very convenient;

if the tide water does not reach the height of the liquid level sensor, the sampling condition is not reached, and the device only detects the tide height but does not sample;

after the tide fades, the staff only need retrieve this device, then open the sealing door body 8 to respectively with sampling bottle 9 take out can from the sampling chamber of difference.
