The purpose of this utility model is achieved through the following technical solutions:
Douche density measurement automatic prompting device of the present utility model, comprise the spacing feeler of water level, the sidepiece of the spacing feeler of described water level is vertically provided with the water feeler lever of testing pits, the spacing feeler of described water level is provided with one or more wire coils, described bottom of testing pits water feeler lever is provided with wire coil, and described wire coil is connected with suggestion device by wire.
The technical scheme being provided by above-mentioned the utility model can be found out, the douche density measurement automatic prompting device that the utility model embodiment provides, owing to comprising the spacing feeler of water level, the sidepiece of the spacing feeler of water level is vertically provided with the water feeler lever of testing pits, the spacing feeler of water level is provided with one or more wire coils, the test pits bottom of water feeler lever is provided with wire coil, wire coil is connected with suggestion device by wire, instrument is light, easy and simple to handle, data are reliable, can automatic-prompting water filling stop, this device is applicable to Subgrade Compaction Quality and detects douche Density Detection in index.
Brief description of the drawings
The structural representation of the douche density measurement automatic prompting device that Fig. 1 provides for the utility model embodiment;
Fig. 2 is the structural representation of the spacing feeler of the utility model embodiment middle water level and the water feeler lever of testing pits.
In figure:
The spacing feeler of 1-water level, the 2-soil body, 3-wire coil, 4-standard is tested pits, 5-suggestion device, the 6-water feeler lever of testing pits, 7-inner lead.
Embodiment
To be described in further detail the utility model embodiment below.
Douche density measurement automatic prompting device of the present utility model, its preferably embodiment be:
Comprise the spacing feeler of water level, the sidepiece of the spacing feeler of described water level is vertically provided with the water feeler lever of testing pits, the spacing feeler of described water level is provided with one or more wire coils, described in the test pits bottom of water feeler lever be provided with wire coil, described wire coil is connected with suggestion device by wire.
Described wire is located at the spacing feeler of described water level and the inside of water feeler lever passing from one end of the spacing feeler of described water level of testing pits.
Described suggestion device comprises sound suggestion device and/or color break-up suggestion device.
The spacing feeler of described water level is horizontally placed on the top of testing pits, described in test pits in water feeler lever tests pits described in stretching into.
Douche density measurement automatic prompting device of the present utility model, has the advantages such as instrument is light, easy and simple to handle, data reliable, automatic-prompting water filling termination, is applicable to railway bed compaction quality and detects douche Density Detection in index.
Cardinal principle of the present utility model is as follows:
In the spacing feeler of water level, the water feeler lever of testing pits, each wire coil, by wire, is connected with the sound and color break-up suggestion device respectively.Along with the rising of the water level water feeler lever wire coil of testing pits is connected by aqueous medium with the spacing feeler wire coil of water level, and this Continuity signal is delivered to the sound and color break-up suggestion device.
The beneficial effects of the utility model can be summarized as following aspect:
Whether 1, adopt the spacing feeler automatic detection of the water level water surface to flush with near coal-mine ground, the sound and the water filling of color break-up suggestion device automatic-prompting, test figure is accurately objective, the water injection rate error that can avoid the manual observation water surface to cause if stopping.
2, this device is light, easy and simple to handle, test speed is fast, and whether laboratory technician does not need the ground proximity observation water surface to flush with near coal-mine ground, and test operation is time saving and energy saving.
3, the scope of application is large.This device is applicable in Subgrade Compaction Quality detection, the various diameters of douche regulation, the Density Detection that the degree of depth is tested pits.
The job step of specific embodiment:
