However, in actual applications, the demand for irrigation water levels will change due to various factors such as crop growth stage, soil moisture, and climatic conditions. Therefore, fixed preset level thresholds are often difficult to meet these dynamically changing needs. Utility Model Content

[0031] In order to make the purpose, technical solutions and advantages of this application more clear, the following Figure 1-3 It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0032] The present application embodiment discloses a liquid level alarm system for agricultural and forestry fields, such as Figure 1-3 As shown, it includes a cylinder 1, a base 2 is fixedly arranged at the bottom of the cylinder 1, and a plurality of plugging rods 9 are fixedly arranged at the bottom of the base 2, so as to facilitate the whole device to be firmly inserted in the agricultural and forestry fields, a plurality of through holes 210 are opened on the bottom surface of the base 2, and a screen 211 is fixedly arranged inside the plurality of through holes 210, and the screen 211 isolates and reduces foreign matter entering the cylinder 1, so as to prevent the accuracy of the liquid level alarm system from being reduced due to excessive foreign matter inside the cylinder 1, and a mounting member 7 is arranged on the top of the cylinder 1;

[0033] The water inlet at the bottom of the cylinder 1 is connected to a plurality of through holes 210, so that water is introduced to keep the water level inside the cylinder 1 at the same height as that outside; a float block 3 is provided inside the cylinder 1, and the outer wall of the float block 3 abuts against the inner wall of the cylinder 1; a sliding sleeve 4 is provided on the outer wall of the cylinder 1, and the sliding sleeve 4 is slidably connected to the cylinder 1; the sliding sleeve 4 is fixedly connected to an alarm component 5; a long hole (not shown in the figure) is provided on the side wall of the cylinder 1, and a part of the alarm component 5 is penetrated through the long hole and slidably connected to the long hole; the sliding sleeve 4 is threadedly connected to an adjustment component 6, and the adjustment component 6 is used to adjust the height of the sliding sleeve 4, and the adjustment component 6 is rotatably connected to the base 2.

[0034] In this embodiment, specifically, the alarm component 5 includes an alarm 510, an alarm button 520, a spring 530 and a slider 540. A slide groove is provided inside the sliding sleeve 4. The spring 530 is fixedly arranged at the bottom of the slide groove. The end of the spring 530 away from the bottom of the slide groove is fixedly connected to the slider 540. The slider 540 is slidably connected to the slide groove. The end of the slider 540 away from the spring 530 is partially penetrated by the long hole, and the end of the slider 540 away from the spring 530 is provided with an inclined surface. The top end surface and the bottom end surface of the floating block 3 are both provided with inclined surfaces. The alarm 510 is fixedly arranged on the surface of the sliding sleeve 4. The alarm button 520 is fixedly arranged on the surface of the sliding sleeve 4. The spring 530 is fixedly connected to the bottom of the slide groove. The end of the spring 530 away from the bottom of the slide groove is fixedly connected to the slider 540. The slider 540 is slidably connected to the slide groove. The end of the slider 540 away from the spring 530 is partially penetrated by the long hole, and the end of the slider 540 away from the spring 530 is provided with an inclined surface. The top end surface and the bottom end surface of the floating block 3 are both provided with inclined surfaces. The button 520 is fixedly set at the bottom of the slide, and the alarm button 520 is electrically connected to the alarm 510. When the float block 3 floats to a preset height due to the water level, the side wall of the float block 3 presses against the slider 540 to make the slider 540 slide toward the bottom of the slide and press the alarm button 520, thereby causing the alarm 510 to sound an alarm. The contact surfaces of the slider 540 and the float block 3 are both inclined, which reduces the horizontal force required when the slider 540 compresses the spring 530, thereby making it easy for the slider 540 to be pushed into the slide. After the float block 3 descends and loses contact with the slider 540, the elastic force of the spring 530 resets the slider 540.

The motor 620 drives the threaded rod 610 to rotate, and the sliding sleeve 4 is driven to move in the vertical direction through the threaded connection between the threaded rod 610 and the sliding sleeve 4, thereby adjusting the height of the sliding sleeve 4.

[0036] The implementation principle of a liquid level alarm system for agricultural and forestry fields in the present application embodiment is as follows:

[0037] The liquid level alarm system is inserted into the agricultural and forestry fields through several insertion rods at the bottom of the base. When the liquid level in the agricultural and forestry fields rises, water enters the cylinder through several through holes opened in the base, causing the float block to float and rise. When the float block rises to the set height, the float block pushes the slider into the slide groove so that the slider presses the alarm button, thereby sounding the alarm; when the liquid level threshold needs to be adjusted, the motor drives the threaded rod to rotate to drive the sliding sleeve to rise or fall, thereby adjusting the height of the slider.

[0038] The above are all preferred embodiments of the present application, and are not intended to limit the protection scope of the present application. Any feature disclosed in this specification (including the abstract and drawings), unless otherwise stated, can be replaced by other equivalent or alternative features with similar purposes. That is, unless otherwise stated, each feature is only an example of a series of equivalent or similar features.
