Description
Technical field
The utility model relates to a kind of sensor, particularly relates to a kind of novel rotating sensor that shakes.
Background technology
The important component part of safety monitoring during the measurement of seepage water pressure, its monitoring result directly affects engineering safety analysis result, therefore needs precision high, and the sensor of dependable performance is measured for long-term.
At present, traditional type sensor is mainly comprised of three parts: pressure imports parts, sensing unit outgoing cable seal member.Wherein sensing unit is the core component of osmometer, and the connection between each parts of sensing unit adopts interference fit mostly, and the mode such as be threaded, makes complicated integral structure, and unstable, and sealing effectiveness is bad simultaneously.
Summary of the invention
The object of this practical confidence is: a kind of simple in structure, stable novel rotating sensor that shakes is provided.
The technical solution of the utility model is: design a kind of novel rotating sensor that shakes, comprise type vibration wire sensing element, protection cylinder, permeable stone, cable and string wire, type vibration wire sensing element is the hollow circular cylinder of a stainless steel, one end of type vibration wire sensing element is flexible pressure containing disk, pressure containing disk and string wire weld together, the string wire other end is fixed on the other end of type vibration wire sensing element, middle part at type vibration wire sensing element is provided with solenoid, it is outside that protection cylinder is welded on type vibration wire sensing element admittedly, the end of protection cylinder is a permeable stone, protection cylinder outside is also connected to cable.
Further, pressure containing disk adopts copper-beryllium alloy to make.
Further, string wire is fixed on the other end of hollow circular cylinder by liquid pressing technology.
Further, described permeable stone is the low air inlet permeable stone of stainless steel sintering.
Further, described protection cylinder is made by stainless steel.
The beneficial effects of the utility model are: string wire is undertaken pre-with fixing by liquid pressing technology, can guarantee that it has high performance stability; Sensor adopts triple waterproofing design, and core sensing element is sealed as a whole, can guarantee that string wire is not corroded, and except string wire, other parts of sensor all adopt the high-quality stainless steel material of high-strength corrosion-resisting, further the permanance of lifting gear.
Accompanying drawing explanation
Fig. 1 is the utility model apparatus structure schematic diagram;
The concrete meaning of number in the figure is: 1. permeable stone; 2. pressure containing disk; 3. string wire; 4. solenoid; 5. protection tin; 6. type vibration wire sensing element; 7. cable.
Embodiment
Below in conjunction with accompanying drawing, with regard to preferred embodiment, the utility model is made to further description.
Referring to Fig. 1, it in figure, is the utility model apparatus structure schematic diagram, the utility model device is by type vibration wire sensing element, outside stainless steel protection cylinder and stainless steel sintering permeable stone form, type vibration wire sensing element outward appearance is the hollow circular cylinder of a stainless steel, its one end is for experiencing the flexible pressure containing disk (copper-beryllium alloy) of hydrodynamic pressure, one end and the pressure containing disk of string wire weld together, the other end adopts liquid pressing technology to be fixed on the other end of hollow circular cylinder, at the middle part of hollow circular cylinder, there is a solenoid that is used for exciting string wire to vibrate and measures its natural frequency of vibration.The natural frequency of vibration of string wire is for being applied to sensing unit---and the hydrodynamic pressure on flexible pressure containing disk is very sensitive; external cable connects the change that readout instrument can be measured its natural frequency of vibration; just can calculate the variation of corresponding hydrodynamic pressure; the end of outside stainless steel protection cylinder is the low air inlet permeable stone of a stainless steel sintering; can protect inner sensor only to experience tested hydrodynamic pressure; and solid particulate matter is intercepted, and permeable stone is easy to take off and carries out saturated processing.
Finally should be noted that: above embodiment is only in order to illustrate that the technical solution of the utility model is not intended to limit; Although the utility model is had been described in detail with reference to preferred embodiment, those of ordinary skill in the field are to be understood that: still can modify or part technical characterictic is equal to replacement embodiment of the present utility model; And not departing from the spirit of technical solutions of the utility model, it all should be encompassed in the middle of the technical scheme scope that the utility model asks for protection.
