Specific embodiment
Embodiment 1
As shown in Figure 1-3, accumulated snow parameter measurement instrument, is made of host and measuring scale, measuring scale includes master axis, measuring rod, Jie
Electric constant sensor and temperature sensor, there is scale on the outside of measuring scale, measuring scale be it is hollow, master axis is longitudinally inserted from top to bottom
Enter measuring scale, master axis is cylinder, and there is longitudinal gear in outside, is provided with a pair of of measurement at regular intervals on measuring scale
Bar, this in same level height, is laterally embedded into the preformed hole of measuring scale measuring rod, and master axis is clipped among it,
It has longitudinal gear matched with master control shaft gear with master axis contact surface, and dielectric constant sensor and temperature sensor distinguish position
In the outer end of a pair of of measuring rod, sensor is connected by conducting wire with host, in use, measuring scale is inserted vertically into accumulated snow bottom, revolves
Turn master axis, by gear drive, measuring rod, which moves horizontally, is pierced by preformed hole, and sensor is inserted into accumulated snow, reads on host
The accumulated snow parameter that sensor measures.Temperature sensor can also be replaced with humidity sensor etc., to increase measurement parameter type.
Measuring scale lower end is tip.Tip is convenient in measuring scale insertion accumulated snow.
Master axis upper end is fixed with knob.Knob is convenient for rotation master axis.
A pair of of clamping end is provided in measuring scale, clamping end clamps each pair of measuring rod, so that between measuring rod and master axis
Gear keep effectively connection.When rotating master axis, the gear between measuring rod and master axis has repulsion, and clamping end can be offset
Repulsion guarantees that gear is effectively driven.
The length direction of measuring rod is parallel to the width direction of measuring scale, and the length of measuring rod is greater than measuring scale width
90%.When being inserted into accumulated snow due to measuring scale, the accumulated snow that will lead to measuring scale contact position generates compressional deformation, thus the product in the region
Snow parameter can also change, and measuring rod can stretch out the half of itself length under the structure, when the length of measuring rod is longer, make
The sensor for obtaining measuring rod outer end can stretch out measuring scale certain distance, avoid measuring the accumulated snow parameter near measuring scale contact position
Brought error.
