Abstract
A well-used dynamic water level measurer belonging to a water level measuring device, in particular to the well-used dynamic water level measurer is provided. A transmission heavy hammer consists of an upper part and a lower part combined by a screw. The partial upper part of the transmission heavy hammer is provided with a small bin with holes at the upper and the lower part; between the upper and lower holes in the small bin hangs a transmission electrode; the upper and lower end of the transmission line of the measuring rope-transmission line are respectively connected with a display device and the transmission electrode arranged in the transmission heavy hammer. So the utility model overcomes the defects of that the deeper dry moist points can not be identified and the descending speed of the water level can not be detected caused by that the ground water leaks from the well wall in measuring the water level with the measuring rope nowadays. The utility model has a reasonable structure, a simple manufacture, a convenient maintenance and operation, a low cost, a high measuring precision, and can be applied to the water level measuring work of all ground water well.
Description
Affiliated technical field
The utility model belongs to a kind of level measurement device, especially a kind of well dynamic water table measuring appliance.
Background technology
At present, at Hetao Irrigation District, utilize abundant groundwater resources, irrigate the area that those physical features are higher, canal system long, the Huanghe water irrigation is relatively more difficult, when planting vegetables, planting flower or the plantation of other industrial crops, also need digging well to get water, record down the extraordinary plantation contradiction different with the field planting water phase in order to overcome wheel.The exploitation of a large amount of groundwater resources makes groundwater table decreasing obviously accelerate, and carries out water-saving irrigation and has become the only way that Hetao Irrigation District underground water uses.
It is generally acknowledged that rapid more just water saving is more irrigated in the soil of unit area, because reduced inhomogeneous irrigation leakage.The Hetao Irrigation District 12-80 rice water bearing ground that is intersected to form by ancient the Yellow River and flood impact in front of the mountains belongs to " streaky pork " distribution more, closely interior different culvert pipe well per hour water yield changes between the 60-160 cubic meter, select suitable water pump type and model, the water saving meaning is very great.
The capacity of outlet water of well is depended in the selection of water pump type and model, measures the well capacity of outlet water and generally adopts the dynamic water level mensuration, promptly drawing water drawdown speed in the observation unit time in the submersible pump lower going-into-well close with estimating water yield.If the slow and stable level of drawdown speed is on certain higher position of submersible pump in the certain hour, can carry out identical test according to the water pump that experience exchanges bigger water yield for; If the very fast drawdown simultaneously of drawdown speed is to submersible pump main frame position in the certain hour, can carry out identical test according to the water pump that experience exchanges less water yield for; If the moderate and drawdown of drawdown speed can be installed and used according to the selected water yield water pump close with lift of experience to certain rational position of submersible pump in the certain hour.Tradition observation dynamic water level is at water pump operation after a period of time, with lining rope is that a weight is gone into the well, and observes dried wet point position obtain data, because existing underground water oozes pouring from the borehole wall near 12 meters, darker dried wet point almost is beyond recognition, and drawdown speed can't be measured especially.
Summary of the invention
In order to overcome existing well level measurement device above shortcomings, this reality is novel to provide a kind of improved well dynamic water table measuring appliance.
The purpose of this utility model is achieved in that and comprises sensing weight, lining rope---the well dynamic water table measuring appliance of sense line and display unit, its design feature is: the sensing weight is combined with the spiral shell button by two parts up and down, the sensing weight on the upper side portion be provided with a up and down porose little storehouse, the sensing electrode that suspends between the hole up and down in little storehouse; The upper and lower side of and lining rope---sense line links to each other with the sensing weight with display unit respectively.The sense line upper and lower side of lining rope---sense line links to each other with sensing electrode in being arranged on the sensing weight with display unit respectively.Described display unit can be universal meter.
The utility model has the advantages that: owing to adopted sensor measurement well dynamic water table, thereby can install and use according to the selected water yield water pump close with lift of the accurate well dynamic water table of measuring, realized the purpose of quick selection water pump type and model.Use this well to begin to get final product accurately tracking measurement SEA LEVEL VARIATION situation easily from water pump operation with the dynamic water table measuring appliance.The utlity model has rational in infrastructure, make simple, attended operation is convenient, low, the measuring accuracy advantages of higher of cost.
Description of drawings
The utility model will be further described below in conjunction with drawings and Examples.
Fig. 1 is a structural representation of the present utility model
Fig. 2 is the utility model user mode schematic diagram
Among the figure: 1, sensing weight, 2, lining rope---sense line, 3, display unit, 4,5 sensing weights are two parts up and down, and 6, the spiral shell button, 7,8 sensing weights are the hole up and down, and 9, the little storehouse of sensing weight, 10, sensing electrode, 11, universal meter.
The specific embodiment:
As shown in Figure 1, 2, comprise sensing weight 1, lining rope---the well dynamic water table measuring appliance of sense line 2 and display unit 3, its design feature is: sensing weight 1 is combined by two parts 4,5 usefulness spiral shell buttons 6 up and down, sensing weight 1 on the upper side portion be provided with a up and down little storehouse 9 of porose 7,8, sensing electrode 10 suspends between the hole up and down 7,8 in little storehouse 9; The upper and lower side of and lining rope---sense line 2 links to each other with sensing weight 1 with display unit 3 respectively.The sense line upper and lower side of lining rope---sense line 2 links to each other with sensing electrode 10 in being arranged on sensing weight 1 with display unit 3 respectively.Display unit 3 is a 10K resistance grade universal meter 11.
When water by the sensing weight under hole 8 when entering the little storehouse 9 of sensing weight and flooding to sensing electrode 10, indicator has 30% the amplitude of oscillation on the 10K resistance grade, this moment, the length of lining rope-sense line 2 just was water level depth.
