Technical Field

[0001] The utility model relates to the technical field of water conservancy irrigation, in particular to a monitoring and alarm system for water conservancy irrigation. Background Art

[0002] Water conservancy irrigation is mainly used to irrigate crops. During irrigation, water from one place is mainly pumped to water-scarce farmland. During the irrigation process, people need to observe the amount of irrigation at all times to avoid over-irrigation or under-irrigation. The existing method is mainly based on human visual observation, which is inefficient and requires people to keep an eye on the water level. In addition, for fields with uneven terrain, people need to keep walking and observing. In order to reduce people's labor intensity, this application sets up an interval alarm system.

DETAILED DESCRIPTION

[0022] The embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0023] like Figure 1-3 In this embodiment, a water conservancy irrigation monitoring and alarm system includes:

[0024] Support plate 60;

[0025] The sound and light alarm 70 and the electric control box 80 are respectively arranged on the upper surface of the support plate 60;

[0026] A plurality of insertion rods 50 are respectively and vertically fixedly connected to the four sides of the lower surface of the support plate 60 and are parallel to each other;

[0027] The lifting plate 10 is located below the support plate 60, and the insertion rod 50 slides through the lifting plate 10 and is detachably fixedly connected to the lifting plate 10;

[0028] The positioning barrel 20 passes through the lifting plate 10 and is fixedly connected to the lifting plate 10;

[0029] The liquid level meter 30 is disposed in the positioning barrel 20 , and the detection rod 31 of the liquid level meter 30 passes through the positioning barrel 20 and is parallel to the insertion rod 50 ;

[0030] The electric control box 80 contains a PLC controller, a control switch, and a battery. The PLC controller is electrically connected to the control switch, the battery, the sound and light alarm 70 , and the liquid level meter 30 .

[0031] This embodiment is implemented as follows:

[0032] When the present application is in use, the insertion rod 50 is first inserted into the position for measuring the water level, and then the lifting plate 10 is moved on the insertion rod 50. The lifting plate 10 drives the positioning bucket 20 to move, and the positioning bucket 20 drives the liquid level meter 30 to move. The height of the liquid level meter 30 is adjusted to maintain a set distance between the lower end of the detection rod 31 and the soil. Then, the lifting plate 10 and the insertion rod 50 are fixed. When the water level rises, the detection rod 31 can gradually detect the height of the water level. When the water level reaches the set height, the PLC controller will receive the data signal of the liquid level meter 30 and then control the sound and light alarm 70 to start to remind the observer.

[0033] The PLC controller, control switch and battery used in this application were all purchased directly.

[0034] The advantage of the present application over the prior art is that it can detect the irrigation water level.

[0035] See also Figure 1 、 2 3. A positioning sleeve 51 that penetrates the lifting plate 10 is fixedly connected to the position of the insertion rod 50 on the lifting plate 10. The insertion rod 50 slides through the positioning sleeve 51. The positioning sleeve 51 has a locking bolt 52.

[0036] The insertion rod 50 can slide in the positioning sleeve 51 through the positioning sleeve 51 , and the insertion rod 50 can be fixed in the positioning sleeve 51 through the locking bolt 52 .

[0037] See also Figure 1 、 2 A threaded sleeve 41 is provided on the lower surface of the positioning barrel 20 , and the threaded sleeve 41 is detachably connected to the mesh cover 40 through a thread, and the detection rod 31 passes through the threaded sleeve 41 and extends into the mesh cover 40 .

[0038] The mesh cover 40 can be connected to the threaded sleeve 41 so that the mesh cover 40 surrounds the detection rod 31 to prevent debris from affecting the accuracy of the detection rod 31.

[0039] See also Figure 1 、 2 3. The upper port of the positioning barrel 20 is connected to the barrel cover 21 through threads.

[0040] The upper port of the positioning barrel 20 can be sealed by the provided barrel cover 21 to protect the liquid level meter 30 . The positioning barrel 20 in the present application has a wiring hole that can be connected to the data line and the wire in the electric control box 80 .

[0041] See also Figure 1 , the number of the insertion rods 50 is at least three.

[0042] Two insertion rods 50 or one insertion rod 50 have poor stability.

[0043] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the creative concept of the present invention, which all fall within the scope of protection of the present invention.
