Self-cleaning sensor for soil humidity and temperature measurement and measurement support

Abstract

The invention provides a self-cleaning sensor for soil humidity and temperature measurement and a measurement support, relates to the field of soil temperature and humidity measurement, and solves a problem that the service life of the sensor is affected due to the fact that collision and scratch protection of the sensor cannot be realized through structural improvement and a problem that the surface of the sensor cannot be automatically cleaned in the process of pulling out the sensor from the soil. The invention discloses a self-cleaning sensor for soil humidity and temperature measurement and a measurement support. The self-cleaning sensor comprises a main body frame, wherein the main body frame is slidably connected with a sliding frame, and the sliding frame is slidably connected witha detection frame. The sensor is advantaged in that a head end of the elastic telescopic box is of an inclined structure, and a shifting arm is in contact with the head end of the elastic telescopicbox when sliding up and down; when the shifting arm slides downwards and makes contact with the elastic telescopic box, the elastic telescopic box is in an elastic contraction state under the limit ofthe stop lever at the moment, when the shifting arm slides upwards and makes contact with the elastic telescopic box, the elastic telescopic box is in an anticlockwise rotation state, and a telescopic gas cylinder is in an extrusion state at the moment.

Description

technical field [0001] The invention belongs to the technical field of measuring soil temperature and humidity, and more specifically relates to a self-cleaning sensor and a measuring bracket for measuring soil humidity and temperature. Background technique [0002] For the burial of soil moisture and temperature sensors, the conventional method is to manually dig out a section in the soil to be measured. The deeper the sensor is buried, the larger the soil section needs to be dug. Therefore, it is often time-consuming to install several soil moisture and temperature sensors. laborious and time-consuming work. [0003] For example, application number: CN201010261072.3, the present invention discloses a soil moisture sensor installation device, including a runner, a bracket, a connecting rod connecting the runner and the bracket, forks located on both sides of the bracket, The upper slider at the lower part of the bracket, and the lower slider fixed at the lower part of the ...

Problems solved by technology

[0007] In order to solve the above-mentioned technical problems, the present invention provides a self-cleaning sensor and a measuring bracket for soil humidity and temperature measurement, to solve the existing problem that the existing devices often directly insert the measuring device into the soil when measuring, Then, in the process of digging into the soil, the sensor cannot be protected from scratches and scratches through structural improvements, which will affect the service life of the sensor; moreover, the sensor needs to be cleaned after the sensor is taken out after the measurement is completed. There is a problem that the device cannot automatically clean the surface of the sensor during the process of extracting the sensor from the soil
