Description

Technical Field

[0001] The utility model relates to the technical field of water level monitoring equipment, in particular to a farmland irrigation water level monitor. Background Art

[0002] Polders are unique agricultural production areas that utilize embankments to isolate fields from surrounding waterways, enabling the rational management of water resources. Traditional polder management typically employs a hierarchical drainage and water storage scheme to address varying hydrological conditions. During flood seasons, drainage ditches connected to the surrounding river network drain water, rapidly lowering the water level within the polder and minimizing flooding losses. During droughts, sluice gates are closed to store water, maintaining soil moisture and ensuring agricultural production.

[0003] In actual agricultural production, it is very necessary to monitor the water level in drainage ditches. However, in the existing technology, monitoring the water level in drainage ditches usually relies on manual observation or a simple buoy mechanism, which is time-consuming and labor-intensive and easily affected by subjective errors, making it difficult to achieve precise regulation. At the same time, when the water level is too low or too high, timely alarm reminders cannot be achieved. Utility Model Content

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0032] Example:

[0033] See also Figure 1 -

[0034] Figure 3 A farmland irrigation water level monitor includes a bridge plate 1, with support plates 2 fixedly connected to both sides of the bottom of the bridge plate 1. The two support plates 2 are respectively supported on both sides of the ditch, so that the bridge plate 1 can be suspended above the ditch for water level monitoring.

[0035] In this embodiment, Figure 1 As shown, side plates 3 are fixedly installed on the opposite sides of the two support plates 2, which can make the support of the support plates 2 more stable. Plug holes 4 can also be evenly opened on the side plates 3, and auxiliary devices such as wooden sticks and rods can be inserted into the soil through the plug holes 4 to further ensure the stability of the bridge plate 1. If both sides of the ditch are concrete, heavy objects such as bricks can be used to press down the side plates 3.

[0036] like Figure 2As shown, a floating plate 5 is provided below the bridge deck 1. The floating plate 5 floats on the water in the ditch. An observation rod 7 is installed on the top of the floating plate 5. The observation rod 7 is movably inserted into a rod slot 8. The rod slot 8 is provided on the bridge deck 1. A scale bar is also provided on the outer wall of the observation rod 7. The floating plate 5 floats with the change of the water level in the ditch, thereby driving the observation rod 7 to move. By checking the height of the observation rod 7 protruding from the bridge deck 1, the water level can be intuitively understood, thereby achieving accurate monitoring.

[0037] In this embodiment, a threaded rod 6 is fixedly installed on the top of the floating plate 5, and the bottom end of the observation rod 7 is threadedly connected to the threaded rod 6, so that the position of the threaded rod 6 can be adjusted, and then the initial height of the threaded rod 6 can be controlled to adapt to ditches of different depths.

[0038] like Figure 2 As shown, two side rods 9 are fixedly installed on the top of the floating plate 5, and the two side rods 9 are movably inserted on the bridge plate 1. The outer walls of the two side rods 9 are movably provided with mounting plates 14, and the mounting plates 14 are fixedly installed with monitoring sensors 15.

[0039] In this embodiment, the monitoring sensor 15 includes a low-position monitor and a high-position monitor, wherein the high-position monitor is fixedly mounted on the top of one mounting plate 14 and the low-position monitor is fixedly mounted on the bottom of the other mounting plate 14;

[0040] When the water level in the ditch is too high, the high-level monitor contacts the bridge deck 1, thereby triggering an alarm. When the water level is too low, the low-level monitor contacts the bridge deck 1, thereby triggering an alarm. Thus, the function of automatic alarm when the water level is too low or too high is realized.

[0041] The monitoring sensor 15 can be a pressure sensor or an infrared ranging sensor, the output end of which is electrically connected to the controller, and the output end of the controller is electrically connected to the input end of the alarm. The alarm can be set as a buzzer and a warning light, installed on the bridge board 1 to realize the alarm function;

[0042] The device can be powered by solar panels to achieve energy conservation and environmental protection; in addition, the specific circuit design of the controller and alarm can select an appropriate integration solution according to actual needs.

[0043] like Figure 2 As shown, a screw rod 10 is rotatably provided inside the side insertion rod 9. The bottom end of the screw rod 10 is rotatably mounted on the inner wall of the side insertion rod 9, and the top end extends to the outside of the side insertion rod 9 and is fixedly connected to a knob 11. The outer wall of the screw rod 10 is threadedly connected to a nut 12, and the nut 12 is fixedly connected to the mounting plate 14 through a connecting block 13.

[0044] Turning the knob 11 can rotate the screw rod 10, and the rotation of the screw rod 10 drives the nut 12 connected to its outer wall thread to move up and down. The up and down movement of the nut 12 can drive the mounting plate 14 to move up and down through the connecting block 13, thereby adjusting the initial height of the mounting plate 14 and the monitoring sensor 15 thereon to control the alarm range (threshold).

[0045] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
