Description

Technical Field

[0001] This utility model relates to the field of walnut low-temperature freezing damage monitoring technology, specifically a walnut low-temperature freezing damage monitoring and early warning device. Background Technology

[0002] Walnuts, as an important economic forest tree species, are extremely sensitive to temperature changes during their growth and development, especially in spring when they are budding, flowering, and growing new shoots. Low temperatures and freezing damage can easily lead to frostbite on flower buds, withering of new shoots, and hindered fruit development, potentially causing significant yield reductions or even total crop failure. Therefore, real-time monitoring and accurate early warning of low-temperature conditions in walnut orchards are crucial measures to ensure the stable development of the walnut industry. However, current walnut low-temperature freezing damage monitoring and early warning devices are mostly fixed-point monitoring devices with non-adjustable heights, making them difficult to adapt to walnut trees at different growth stages. Therefore, we propose a walnut low-temperature freezing damage monitoring and early warning device. Utility Model Content

[0024] The base plate 1 of this technical solution provides basic support for the device. The motor 2 at the top center drives the threaded rod 10 to rotate. The threaded tube 6, with the cooperation of the guide block 17 on the left and the guide groove 16 on the right of the vertical plate 3, drives the top plate 7 to rise and fall, realizing the height adjustment of the temperature detector 8 and humidity detector 9 to adapt to the monitoring needs of walnut branches of different heights.

The alarm 5 on the left side of the vertical plate 3 issues an early warning when the monitored data reaches the threshold.

[0025] Example 2:

[0026] Based on Embodiment 1, this utility model is as follows: Figure 1-4As shown, the top plate 7 has a first groove 21 at its bottom. A pull rod 23 is movably connected to the inner cavity of the first groove 21. A second connecting plate 20 is fixedly connected to the left end of the pull rod 23. A second groove 24 is formed at the top of the first connecting plate 11. A slot 26 is formed on the left side of the inner cavity of the second groove 24. A plug 25 is fixedly connected to the bottom left side of the second connecting plate 20. The plug 25 is movably connected to the inner cavity of the slot 26. A spring 22 is sleeved on the outer surface of the pull rod 23. One end of the spring 22 is fixedly connected to the right side of the inner cavity of the first groove 21. The left end of the spring 22 is fixedly connected to the right side of the second connecting plate 20. The right end of the pull rod 23 is fixedly connected to the pull ring 12.

[0028] The working principle of this utility model is as follows: During use, the electric telescopic rod 28 is activated by the PLC controller 4 on the front and rear fixed plates 13 of the base plate 1, which drives the pin 27 to be inserted into the soil to firmly fix the equipment; according to the height requirements of walnut tree monitoring, the controller starts the motor 2, which drives the threaded rod 10 to rotate. The threaded tube 6 drives the top plate 7 to rise and fall under the guidance of the guide block 17 and the guide groove 16 until the temperature detector 8 and the humidity detector 9 are aligned with the target monitoring part; pulling the pull ring 12 moves the pull rod 23 to the right, compresses the spring 22, and aligns the positioning block 19 on the top of the first connecting plate 11 with the positioning groove 18 of the top plate 7 and puts it in. Releasing the pull ring 12, the spring 22 returns to its original position and pushes the second connecting plate 20 to the left, and the pin 25 is inserted into the slot 26 to complete the fixing of the detector; the temperature detector 8 and the humidity detector 9 collect data in real time and transmit it to the PLC controller 4. When the data reaches the low temperature freezing damage threshold, the controller activates the alarm 5 on the left side of the vertical plate 3 to issue a warning; during the monitoring process, the battery box 15 ensures the operation of the equipment when the power is off, and the tool box 14 can provide maintenance tools.
