Embodiment
, in order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
as Fig. 1 ~ shown in Figure 4, structure of the present utility model comprises main scale, secondary chi, button cell bin and battery e, light emitting diode f, lock screw h, wire i, wherein have a groove on secondary chi, main scale is embedded in this groove, there is A scale a on the right side of main scale, there is A vernier b the lower right side of secondary chi, there is B scale c in the left side of secondary chi, the lower-left end of main scale has B vernier d, button cell bin and battery e are arranged on the top of secondary chi, light emitting diode f is arranged on the upper right quarter of secondary chi, lock screw h is arranged on the upper left quarter of secondary chi, the left and right sides, lower end of secondary chi arranges respectively left chaining pin and right chaining pin, it is inner that wire i is arranged on secondary chi, left chaining pin, button cell bin and battery e, light emitting diode f and right chaining pin link together by wire i successively, form closed-loop path.
The upper end middle position of described main scale is provided with horizontal gas bulb apparatus g, is used to indicate the plumbness of main scale.
Contact tight and can mutually slide between this Water level measuring rule design main scale and secondary chi two cover scale devices, main scale and secondary chi, utilizing main scale to overlap different scales from secondary chi two, can read easily the actual water level degree of depth.
In order to indicate whether contacting of secondary chi lower end chaining pin and the water surface, one closed-loop path device (Fig. 5) is set on secondary chi, when the water surface contacts with secondary chi chaining pin, utilize liquid conductivity, make circuit closed, be arranged at that on secondary chi, the light emitting diode f in circuit will be luminous, in time indicate chaining pin to arrive liquid level, the reading of this moment is the actual water level degree of depth.
Agricultural irrigation test (paddy field) is measured the field water layer depth, because of earth's surface, just differs, and is difficult to reach theoretic same level.Therefore, measuring water depth method commonly used is to hammer into a timber in the fixed position, field, and the timber upper end keeps level.Search and Orientation during for the ease of each the measurement, usually expose earth's surface 2～3cm with the timber upper end.While measuring the soil after irrigation water depth, there will be two kinds of water level situations, a kind of be water level to be measured higher than nail timber top, another kind is that water level to be measured is lower than the timber top.
As shown in Figure 6, when water level to be measured pushes up higher than stake, unscrew the lock screw h on secondary chi, will slide to the main scale top on secondary chi, make the zero graduation of A vernier b align with the 20cm place of main scale A scale a.The main scale lower end is placed in the timber top, regulate main scale to vertical state, make the bubble of the horizontal gas bulb apparatus g that is arranged in the main scale top occupy central authorities, with secondary chi slip, until stop when on secondary chi, light emitting diode f is luminous sliding, locking is positioned at the lock screw h of secondary chi, utilizes A scale a on main scale and the A vernier b on secondary chi, read respective value, this numerical value is the degree of depth (in figure reading be 2.38cm) of an apex distance from liquid level.Measure complete after, secondary chi vernier reading is made zero, regulate to make the zero graduation of A vernier b align with the 0cm place of main scale A scale a, lock the lock screw h on secondary chi.
As shown in Figure 7, when water level to be measured pushes up lower than stake, unscrew the lock screw h on secondary chi, secondary chi is slided and adjusts, make the zero graduation of B vernier d align with the 0cm place of secondary chi B scale c.The main scale lower end is placed in the timber top, regulate main scale to vertical state, make the bubble of the horizontal gas bulb apparatus g that is arranged in the main scale top occupy central authorities, with secondary chi slip, until stop when on secondary chi, light emitting diode f is luminous sliding, locking is positioned at the lock screw h of secondary chi, utilizes B scale c on secondary chi and the B vernier d on secondary chi, read respective value, this numerical value be an apex distance from the degree of depth of liquid level (in figure reading for-0.84cm).Measure complete after, the main scale vernier reading is made zero, regulate to make the zero graduation of B vernier d align with the 0cm place of secondary chi B scale c, lock the lock screw h on secondary chi.
