And moreover, the buoyancy of water is fully utilized, the field water level can be accurately controlled, and meanwhile, the power supply is utilized only when the gate is opened or closed in the crop growth period, so that the energy consumption is low. In addition, different numbers of lock chambers can be made according to the irrigation frequency of a certain crop irrigation system in a certain area, and the adaptability is strong.

Example (b):

the irrigation of early rice in a certain irrigation area is taken as an example, and the irrigation system is as follows:

TABLE 1 irrigation schedule for early rice growth period in certain irrigation area

The early rice needs to be watered for 8 times in the growth period, namely 8 control lock chambers 12 are needed. Before first irrigation, arranging the gate control device 2 in the field to enable the bottom plate of the gate control device to be consistent with the elevation of the field surface (or the bottom plate to be consistent with the elevation of the normal water level of the field surface); meanwhile, the arrangement elevation of the bottom of the water inlet gate 1 is consistent with the arrangement elevation of the floor of the gate control device 2. According to the crop irrigation system, the water level of the field surface for each irrigation is determined, and the position of the electric wire contact I17 is further calculated during each irrigation. Calculating by taking one-time irrigation as an example, assuming that the elevation of the contact I17 from the field surface is h, then:

h＝H+a

wherein H is the elevation of the water surface in the field after the irrigation and is directly obtained by an irrigation system; a is the height of the vertical rod exposed out of the water surface under the action of buoyancy in the buoyancy device, and is a measurable fixed constant, for example, the floating ball 13-2 floats on the water surface, and half of the floating ball 13-2 is immersed in the water, when a is equal to the sum of the length of the vertical rod and the radius of the floating ball 13-2 (the metal sheets I19 and II20 are thin sheets, and the thickness is negligible).

The position of the contact I17 is adjusted by retractable connecting wires. The contact I17 on each control device gate chamber is adjusted in position according to the irrigation system and is fixed on the side plates.

Assuming that the elevation of the field surface (the elevation of the normal water level of the field surface) is 1m, and a is 0.1m, the elevation positions of the wired contact I17 and the touch switch 5-1 are shown in the following table according to the irrigation schedule table and the above formula:

TABLE 2 electric wire contact I and switch position table of touch switch

Number of times of irrigation	1	2	3	4	5	6	7	8
									Corresponding lock chamber (counting from the left side)	1	2	3	4	5	6	7	8
Contact, touch switch corresponding elevation (m)	1.14	1.14	1.15	1.15	1.15	1.15	1.14	1.14

Before the first water filling, the water inlet gate 1 is in an open state (refer to fig. 3). When the field surface is anhydrous, the metal sheet II20 of the floating device 13 can enable the contact II18 to be communicated, but the circuit of the connecting wire II5 is not communicated because the contact IV25 is not communicated; since the contact I17 and the touch switch 5-1 are both in the off state, the circuit connecting the circuit I4 and the circuit III6 is off.

Before the first filling of water, the inner control gate 14 is in the closed state (see fig. 4).

After the water flow enters the field surface, the floating device 13 starts to float gradually as the water enters the first control lock chamber 12 until the metal sheet I19 on the floating device 13 abuts against the contact I17, so that the contact I17 is connected. At this time, the circuit I4 is turned on, the gate closing electromagnet 7 generates an acting force opposite to the magnet I9 to push the gate plate of the water inlet gate 1 to the right end, at this time, the water inlet gate 1 is closed, and simultaneously, the contact IV25 can be connected due to the action of the metal sheet III26 on the gate plate of the water inlet gate 1, but the circuit II5 is not connected at this time, because the metal sheet II20 of the floating device 13 is separated from the contact II18, so that the contact is disconnected.

Wherein the electromagnetic force F generated by the electromagnet_QThe water gate is mainly used for overcoming the friction force between the gate plate and the gate frame, the friction force between the gate plate and the water stop and the water resistance, and the value can be determined through the electromagnetic force and the gate opening test. The gate plate can be made of light materials such as polypropylene and the like so that the buoyancy of the gate plate is larger than the self weight, and the friction between the gate plate and the door frame can be reduced. The electromagnet can adopt a sucker type electromagnet, and the model parameters can be selected and matched with the existing models (shown in the following table) in the market according to specific tests.

TABLE 3 electromagnet matching parameter table

With the consumption of water such as water consumption of crops, the depth of the field surface water gradually decreases to be consistent with the height of the field surface (or the normal water level of the field surface), so that the floating device 13 descends to enable the metal sheet II20 on the floating device 13 to press the top contact II18 to be connected, and further enable the circuit II5 and the circuit III6 to be connected.

At this time, when the circuit II5 is turned on, the shutter opening electromagnet I8 at the right end of the shutter frame of the inlet shutter 1 and the magnet II10 at the right end of the shutter plate generate a reaction force to push the shutter plate to the left end, and the inlet shutter 1 is opened.

Meanwhile, as the circuit III6 is switched on, the opening electromagnet II15 in the internal control gate 14 and the magnet III16 generate opposite actions, so that the gate plate of the control gate 14 is pushed to the right end, at the moment, the control gate 14 in the first gate chamber is opened, and as the magnet IV22 and the magnet V23 generate attraction force mutually, the first internal control gate 14 from the left is in an opened state; meanwhile, the floating fixing pull rope is tensioned due to the movement of the gate plate of the control gate 14, so that the floating device 13 is limited to float upwards.

According to the above results, before the water is irrigated for the second time, the whole device is in the state consistent with that before the water is irrigated for the first time, namely the water inlet gate 1 is in an open state; the first lock chamber and the second lock chamber of the lock gate control device 2 are completely opened, and the floating device 13 in the second lock chamber is also in a natural state.

During the second irrigation, the water flow on the field surface can directly enter the second chamber from the left in the gate control device 2. Since the floating device 13 in the first lock chamber is restricted, the rising of the water level does not act on the floating device 13 in the first lock chamber. At this time, the operation process of the second lock chamber from the left in the control device repeats the operation process of the first lock chamber when the water is filled for the first time.

The irrigation process is repeated every time later until the whole irrigation process is finished in the crop growth period.
