Fig. 2 is that uncovered of the present utility model is measured water tank cut-away view;
Fig. 3 is electric control circuit figure of the present utility model;
In figure: uncovered is measured water tank 1, limit switch 2, rocker arm bracket 3, Rocker arm 4, hollow float 5, measures water pipe 6, screen pack 7, waterflooding rice field 8.
Embodiment
Below in conjunction with drawings and Examples, the utility model is described in further detail.
As shown in Figure 1, the utility model comprises linker level measuring part, uncovered measurement water tank internal actions transmitting portions and three functional areas of electric control system.
Described linker level measuring part, comprises with measuring water pipe 6 and connects waterflooding rice fields 8 and measure water tank 1 with uncovered, and in one end of measuring water pipe 6 and being placed in waterflooding rice field, screen pack 7 is installed, and prevents that rice field duckweed is to measuring the obstruction of water pipe 6.
As shown in Figure 1 and Figure 2, described uncovered is measured water tank internal actions transmitting portions, comprises uncovered measurement water tank 1, limit switch 2, rocker arm bracket 3, Rocker arm 4, hollow float 5; On the madial wall of uncovered measurement water tank 1, rocker arm bracket 3 is installed, two arm of forces of Rocker arm 4 are angle and centre is fixed on rocker arm bracket 3, and the upper end arm of force of Rocker arm 4 connects limit switch 2, and the lower end arm of force connects hollow float 5.
Described electric control system, comprises main circuit and control circuit, and main circuit is composed in series by three-phase fusing formula knife-like switch QFS, A.C. contactor KM and electrothermal relay FR; Control circuit is composed in series by limit switch 2, fuse FU and A.C. contactor KM, control circuit by with three-phase electricity L2 and the L3 electric energy that provides in parallel.
Operation principle of the present utility model is as follows:
The utility model is to utilize law of connected vessels to measure water level, by the law of buoyancy of hollow float, provide rocking arm power, utilize lever principle to oppress or unclamp limit switch, the startup that utilizes the A.C. contactor of electrical system to control pump station part motor comes automatic control pump station to irrigate with this.Different functions is realized in three functional areas of the present utility model, and the effect of three functional areas is as follows:
(1) linker level measuring part:
As shown in Figure 1, measurement water pipe 6 by and hard material thinner than water injection pipe connects waterflooding rice field 8 and uncovered measurement water tank 1, in waterflooding rice field ridge outside, excavate and measure space that water pipe 6 thicknesses conform to and embed and measure water pipe 6, because the waterflooding rice field water surface now and the water surface of measuring water tank are all connected with atmosphere, water surface pressure equates, according to law of connected vessels, when waterflooding water level in paddy field is at high-order h
1time, uncovered is measured cistern water level to h
1', there is h
1=h
1'; When water level in paddy field is at low level h
2time, uncovered is measured the h that arrives of cistern water level
2', there is h
2=h
2'.The high low energy of uncovered measurement cistern water level truly reflects the height of waterflooding water level in paddy field like this.
(2) uncovered is measured water tank internal actions transmitting portions:
As shown in Figure 1 and Figure 2, hollow float 5 is that the sealing plastics of hollow are made, according to Archimedes principle, when its cavity is enough large, the weight that it arranges water can surpass its deadweight and making a concerted effort of outside additional downward force, so remainder does not swim on the water surface after hollow float 5 can partly have upstream face.When uncovered is measured cistern water level to high-order h
1' time, hollow float 5 is because buoyancy moves upward, and whole Rocker arm 4 is equivalent to two angled levers of the arm of force, and rocker arm bracket 3 is equivalent to the fulcrum of lever, makes like this limit switch 2 be pushed back, at this moment the state of limit switch 2 in disconnecting; When cistern water level is to low level h
2' time, buoy, due to the effect of the screen resilience of self gravitation and limit switch 2, makes all positions in solid line demonstration of hollow float 5, Rocker arm 4 and limit switch 2, and the circuit that at this moment limit switch 2 connects is connected.The height of waterflooding water level in paddy field has determined that uncovered measures the height of cistern water level, has determined thus the open and-shut mode of limit switch 2, water level during higher than setting value limit switch 2 in off-state; Water level is lower than when setting value, and limit switch 2 is in closure state.
(3) electrical control part:
The irrigation in general waterflooding rice field is all that agricultural pumping plant adopts starter motor to provide the power pouring rice field of drawing water to pump, as shown in Figure 3, when closed three-phase fusing formula knife-like switch QSF, L
2with L
3two phase conductors are in three-phase fusing formula knife-like switch QSF lower end energising, and when water level is during higher than setting value, hollow float 5 moves upward, and forces limit switch 2 to disconnect, and makes A.C. contactor KM coil losing electricity, disconnects KM at L
1, L
2, L
3the contact of three-phase power leads, shuts down after motor power-off, i.e. the pumping plant pouring that stops pumping; When water level is lower, hollow float 5 declines, compressing limit switch 2 closures, and A.C. contactor KM coil obtains electric, and closed KM is at L
1, L
2, L
3the contact of three-phase power leads, starts after electrical power, the pumping plant pouring that starts to draw water; When three-phase fusing formula knife-like switch QSF is under closed state, the switching of limit switch 2 has determined startup and the shutdown of Electric Machine at Pumping Station like this.
