Example Embodiment

[0012] Frozen soil vertical temperature gradient detection sensor, including a housing 1, in which there is a rectangular temperature sensor fixing plate 2. The temperature sensor fixing plate 2 is embedded with four output buses 3 along the length and several groups along the length of the temperature sensor fixing plate A temperature sensor wire group that is evenly distributed in the direction and connected to the output bus. The temperature sensor wire group is composed of four wires 4, and the four wires of the temperature sensor wire group are connected to the four output buses 3 one by one, and the four output buses Lead out the shell 1; each temperature sensor wire group corresponds to a temperature sensor mounting base 5. A screw hole is opened on one end of the temperature sensor mounting base 5, and the screw holes are inserted with four inherent copper posts and the four copper posts are from another One end surface passes through; the other end surface of the temper...

Abstract

The invention relates to temperature sensors, in particular to a frozen soil vertical temperature gradient detection sensor. The problems that no mature method for detecting temperature gradient data exists at present, and an existing method is low in efficiency, high in cost and not beneficial to wide application can be solved. The frozen soil vertical temperature gradient detection sensor comprises a shell, a rectangular temperature sensor fixing plate is arranged in the shell, and four output buses which are arranged in the length direction and a plurality of temperature sensor wire sets which are evenly distributed in the length direction of the temperature sensor fixing plate and connected with the output buses are embedded in the temperature sensor fixing plate. The temperature sensor fixing plate is fixedly connected with a plurality of PT100 temperature sensors which are connected with the temperature sensor wire sets respectively, and one end of each PT100 temperature sensor stretches out of the shell. An epoxy resin packing layer is formed by casting epoxy resin insulating materials in the shell. According to the frozen soil vertical temperature gradient detection sensor, due to the integrated design of the PT100 temperature sensors, temperature gradient detection is achieved, and the sensor is suitable for conducting wide-range, multi-point and continuous detection in a frozen area.

Description

technical field [0001] The invention relates to a temperature sensor, in particular to a vertical temperature gradient detection sensor for frozen soil. Background technique [0002] In recent years, human activities in permafrost areas have become more frequent. Accurately grasping the active layer of permafrost and the formation law of permafrost is the basis for solving practical engineering problems in permafrost areas, and it is also a requirement for ecological environment construction and sustainable and stable development of the national economy. Frost heaving, thawing and freezing and pulling out of permafrost pose a serious threat to the construction and safe operation of railways and electric power projects. However, relevant experience and research are relatively scarce. [0003] Climate is one of the decisive factors for the existence and development of permafrost, and the main climatic factor affecting the distribution of permafrost is surface temperature. Si...
