Description of drawings
Fig. 1 is the structural representation of the utility model soil moisture inductance gauge.
Embodiment
For making the purpose of this utility model, technical scheme and advantage clearer, the utility model is described in further detail below in conjunction with accompanying drawing.
As shown in Figure 1, a kind of soil moisture inductance gauge of the utility model, it comprises vacuum meter 1, sealed tube 3, vitrified-clay pipe 2, discharge 4, rubber stopper 5 and the lid 6 of fixedlying connected with described sealed tube 3 bottoms.Described vacuum meter 1 comprises vacuum gauge outfit 12 and the connecting pipe 11 of fixedlying connected with described vacuum gauge outfit 12.Described discharge 4 is "T"-shaped three-way pipe, be provided with first mouth of pipe 41, second mouth of pipe 42 and be used for the 3rd mouth of pipe 43 of water filling, described first mouth of pipe 41 flexibly connects with described connecting pipe 11 bottoms, described second mouth of pipe 42 is connected with described sealed tube 3 top movable, described the 3rd mouth of pipe 43 flexibly connects with described lid 6, described rubber stopper 5 is filled in described the 3rd mouth of pipe 43 and is flowed out from the 3rd mouth of pipe 43 with moisture in preventing to manage, and described lid 6 is placed in rubber stopper 5 outsides.
Three mouth of pipe 43 of water on discharge 4 enters sealed tube 3, after treating to be full of water in sealed tube 3 and the discharge 4, uses rubber stopper 5 with the 3rd mouth of pipe 43 jam-packs, the lid 6 of screwing on.After the sealing of the soil moisture inductance gauge behind the water-filling, vacuum meter 1 is carried out zero correction, eliminate vacuum meter 1 to the hydrostatic force value between vitrified-clay pipe 2 measuring points, guarantee to measure accurately.In the place that needs measured soil humidity, vertically be embedded in inductance gauge in the soil, vitrified-clay pipe 2 is closely contacted with soil, vacuum gauge outfit 12 is stretched out soil surface to make things convenient for reading of data, vitrified-clay pipe 2 inside are provided with cavity and are furnished with many tiny holes, vitrified-clay pipe 2 can be formed water membrane by behind the water infiltration in hole.When inductance gauge inserts the undersaturated soil of moisture, soil can outwards absorb water from vitrified-clay pipe 2, moisture film just links up with the holard, form the parital vacuum state in the vacuum meter 1, make the water generates negative pressure of inductance gauge inside, vacuum meter 1 indicates corresponding readings, at this moment, the negative pressure of vacuum meter 1 indication is exactly a soil water suction; Irrigate back soil and become moistening, in the sucked back again vitrified-clay pipe 2 of moisture, vacuum meter 1 reading descends, and reads soil moisture tension with this, reflects the soil moisture situation exactly, makes things convenient for agricultural irrigation.In use, the water in the inductance gauge can reduce gradually because of the influence of natural cause, and 4 air containment can be opened lid 6 and rubber stopper 5 carries out moisturizing above a half of discharge 4 volumes in discharge, and is easy to operate.
More preferably, described first mouth of pipe 41 and second mouth of pipe 42 are provided with screw thread, and described the 3rd mouth of pipe 43 outer walls are provided with screw thread; Described connecting pipe 11 bottoms are provided with and the suitable screw thread of described first mouth of pipe 41, and described sealed tube 3 tops are provided with and the suitable screw thread of described second mouth of pipe 42, and described lid 6 inwalls are provided with and the suitable screw thread of described the 3rd mouth of pipe 43.The each several part of inductance gauge is separate, flexibly connects by screw thread, can dismantle at any time, when breaking down or when damaging, does not need integral replacing, only needs to change corresponding parts, just can directly use, and dirigibility is strong.Need to prove that the screw thread of described the 3rd mouth of pipe 43 is located at outer wall, this helps blocking up in the 3rd mouth of pipe 43 places of rubber stopper 5, and moisture flows out from the 3rd mouth of pipe 43 in preventing to manage.
More preferably, described sealed tube 3, discharge 4 and lid 6 adopt duroplasts or organic glass to make.During use, inductance gauge usually needs to suffer the erosion of high wind, rainwater, sunlight and chemical substance, therefore needs to use higher plastics or the organic glass manufacturing of hardness, to increase the serviceable life of inductance gauge.Further, described discharge 4 is a transparent tube.In use, water in the inductance gauge can reduce gradually because of the influence of natural cause, therefore to pay close attention to the capacity of air in the discharge 4 constantly, adopt transparent tube can clearly monitor air containment at any time, 4 air containment surpasses a half of discharge 4 volumes in discharge, just need carry out moisturizing.
More preferably, the length of described sealed tube 3 is 300 ~ 800 ㎜.The length of sealed tube 3 has directly influenced the overall length of whole inductance gauge, and inductance gauge is long, and wind-engaging, rain shadow ring bigger, causes inductance gauge loosening with the soil that originally contacts easily, influences measurement effect; Inductance gauge is too short, is unfavorable for that then the user reads the data of vacuum meter 1.
As from the foregoing, implement the utility model, the user can measure the humidity of soil exactly, make things convenient for agricultural irrigation, in addition, each assembly of the present utility model is separate, has dismountable characteristics, simple in structure, when breaking down or when damaging, the user does not need integral replacing, only needs to change corresponding parts, just can directly use, avoid the wasting of resources.
The above is a preferred implementation of the present utility model; should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the principle of the invention; can also make some improvements and modifications, these improvements and modifications also are considered as protection domain of the present utility model.
