Description
Technical field:
The utility model relates to a kind of to internal tank liquid-level tracking device for monitoring.
Background technology:
Current is to adopt the heavy formula liquid level monitor of gravity ball float difference, the convertible liquid level monitor of magnetic and pressure sensitive liquid level monitor etc. to the internal tank level monitoring substantially, these products exist monitoring accuracy low, temperature drift is big, full accuracy just can reach 0.5 centimetre, and diamagnetic interference and electric field interference performance are poor, often produce the false alarm phenomenon, these product design sizes are big, difficulty is installed, debug loaded down with trivial details, shortcomings such as failure rate height.
The utility model content:
The utility model is to design for the defective that solves present liquid level monitor existence.Its technical scheme is: driving wheel is linked to each other with stepper motor by main drive shaft one end, and the other end links to each other with the bearing of being fixed by bearing cap on the driving wheel support, and stepper motor and driving wheel support are fixed on the upper bearing plate.Engaged wheel is fixed on fixedly orifice plate center by follower shaft and two lower carriages, with four support columns upper bearing plate and lower fixed hole plate are connected and fixed, and adjust make the direction and position consistency of driving wheel and engaged wheel after, further fix four support columns, upper bearing plate and lower fixed hole plate.Be fixed on the optocoupler fixed head after rising photocoupler set and decline photocoupler set be close together respectively, and then the optocoupler fixed head is screwed at float protects on the frame.The control line of the two groups of optocouplers that rise, descend is passed through the spiral elasticity cable connection to electric control box, electric control box and stepper motor are linked together by the Electric Machine Control cable.Put into the float that has T type light barrier in the middle of the photoelectricity hole of two groups of optocouplers of rising, descend, float protects the frame upper end and connects with shackle line, and the shackle line other end connects with wire rope preloading spring upper end after walking around driving wheel; Float protects the frame lower end and connects with shackle line, the shackle line other end walks around engaged wheel and wire rope preloading spring lower end connects, the wire rope preloading spring makes the shackle line on driving wheel and engaged wheel have certain tension force, and this tension force can make shackle line that sliding phenomenon is not arranged on driving wheel.On the upper bearing plate and lower fixed hole sleeve-board that will be fixed together with four support columns with sealing bore, upper bearing plate is fixed on the sealing bore driving wheel and engaged wheel direction and position consistency with the upper bearing plate set bolt.
The utility model principle of work is: original state is that float makes T type light barrier fixed thereon be in rising photoelectricity hole and middle edge place, decline photoelectricity hole, and promptly T type light barrier does not block any one group of photoelectricity hole.When liquid level rises, float also rises thereupon, just make T type light barrier rising backstop live in to rise the photoelectricity hole, thereby the rising photocoupler set is sent rising signals to electric control box, electric control box just sends the rising pulse signal to stepper motor, stepper motor is just transferring to be carried float and protects frame, mentions T type light barrier always and does not block till the rising photoelectricity hole; When liquid level descends, float descends, after thereby T type light barrier also descends and shelters from decline photoelectricity hole, the decline photocoupler set is just sent dropping signal to electric control box, electric control box just sends the falling pulse signal to stepper motor, the reverse float that descends of stepper motor protects frame, drops to T type light barrier always and does not block till the decline photoelectricity hole.Electric control box is blocked rising photoelectricity hole or decline photoelectricity hole when not blocking by calculating from T type light barrier, issue the umber of pulse of stepper motor forward or reverse, the distance that just can reach the rising of monitoring liquid level or descend, each pulse all has a corresponding parasang, and float and T type light barrier all are to be made by aluminium alloy.Machine prevents that with wool felt the mist of oil in the sealing bore is excessive.
The utility model is reasonable in design, and is simple in structure, the measuring accuracy height, and easy for installation, antijamming capability is fabulous, is widely used in level monitoring fields such as electric power, chemical industry, medicine.
