Description

Tool for unloading TDP probe

Technical Field

The utility model mainly relates to the technical field of forestry monitoring tools, in particular to a tool for unloading a TDP probe.

Background

In forestry monitoring operation, the TDP probe type plant stem flow (liquid flow) sensor can be used for measuring stem flow of trees with chest stems larger than 70 mm, and multiple sensors are needed to be inserted into a single tree due to the fact that the stem flow is different in the circumferential direction of the tree.

The monitoring operation mode of the existing TDP probe type plant stem flow (liquid flow) sensor is divided into a U-shaped structure body consisting of an upper probe and a lower probe and is inserted into a trunk at the same time, and the working principle is that the sensor comprises two thermocouple probes which are inserted into the sapling of the tree, the upper probe is responsible for heating, the probe measures the temperature difference (dT) between the heating probe and the ambient temperature of the lower side measuring sapling, the change of dT and the maximum dTm at the time of zero stem flow provide direct and calibrated conversion of stem flow speed, and the measured stem flow speed is converted into volume flow;

when an operator performs the disassembly work of the needle body, a special tool shown in fig. 4 is needed, and the needle body is pulled out of the trunk by prying by adopting the special tool, so that the disassembly is realized;

however, in connection with practical applications, we find that the existing special tools have the following disadvantages: when the TDP heating probe is unloaded, the angle of the tool cannot be vertical to the heating probe, so that the heating probe is inconvenient to unload, and the probe is distorted because the gravity center of the heating probe is not on the same axis as the gravity center of the side probe is unloaded, and the upper probe and the lower probe are possibly not on the same horizontal plane, so that the probability of damage and bending of the probe is greatly increased.
