Soil temperature detection device

The utility model relates to the technical field of temperature detection, in particular to a soil temperature detection device, which comprises a support frame, a temperature sensor and a data collection module, the multiple supporting frames are arranged in soil in parallel. Wherein the distance between the supporting frames and the upper surface of soil is 20-40 cm, a plurality of temperature sensors perpendicular to the supporting frames are arranged on each supporting frame, the distance between the temperature sensors on the same supporting frame is 1 m, and each temperature sensor comprises a junction box, a thermocouple, a stainless steel protection tube and an outgoing line sleeve; wherein the upper part of the junction box is fixed on the support frame, the lower part of the junction box is connected with a stainless steel protective tube, the lower part of the stainless steel protective tube is connected with a thermocouple, and one side of the junction box is provided witha lead-out wire sleeve. The temperature sensor is required to be mounted in the vertical direction, so that the temperature changes of the soil at different depths can be detected, the situation thatthe soil at different depths needs to be detected by different temperature sensors in the prior art is replaced, and the cost and the working efficiency are greatly reduced. 本实用新型涉及温度检测技术领域，特别涉及一种土壤温度检测装置，包括支撑架、温度传感器、数据收集模块；若干支撑架相互平行的设置在土壤里，支撑架与土壤的上表面距离为20厘米至40厘米，每个支撑架上配置有若干垂直于支撑架的温度传感器，同一支撑架上的温度传感器之间的间距为1米，温度传感器包括接线盒、热电偶、不锈钢保护管以及引出线套管；接线盒的上方固定在支撑架上，接线盒下方连接有不锈钢保护管，不锈钢保护管下方连接有热电偶，接线盒的一侧设有引出线套管。在竖直方向就需要安装一个温度传感器，就可以检测不同深度的土壤的温度拜变化，取代了现有技术中不同深度的土壤需要不同的温度传感器来检测，极大节约了成本和工作效率。
