Further, in above-mentioned ground temperature field waterproof temperature probe, described thread seal structure comprises pipe box and screw, and described pipe box and guard tube are connected and have internal thread, have on the described screw can with the external thread of this screw-internal thread fit.The thread seal structure here can seal the alternative form that needs are taked multiple various kinds according to reality.
In above-mentioned ground temperature field waterproof temperature probe, the diameter of described pipe box is greater than the diameter of guard tube.This structure makes that the connection of screw thread is more fastening, has strengthened sealing effectiveness.
In above-mentioned ground temperature field waterproof temperature probe, have the step that this screw can be divided into threaded portion and knob on the described screw, described external thread is arranged on the threaded portion.The setting of step can make things convenient for screwing of screw.
In above-mentioned ground temperature field waterproof temperature probe, described seal plug is U type structure.The version of the seal plug here also can be taked the alternative of multiple various kinds.
In above-mentioned ground temperature field waterproof temperature probe, described seal plug and guard tube are fixed with one.
In above-mentioned ground temperature field waterproof temperature probe, described guard tube is made by polythene material.
In above-mentioned ground temperature field waterproof temperature probe, described guard tube diameter is 15mm-25mm.
In above-mentioned ground temperature field waterproof temperature probe, described temperature sensor is evenly distributed in the guard tube.
Compared with prior art, the advantage of this ground temperature field waterproof temperature probe is: reasonable in design, simple in structure, with low cost, and long service life, good water-proof effect, reliability is higher.
