Abstract
The utility model provides a floating roof inclination predictor of a floating roof tank. The predictor comprises a monitoring mechanism consisting of a base, a middle cover, a top cover, a ball pendulum, a variable frequency coil and an annular thermistor, and a signal processing system consisting of a balance bridge, an amplifying circuit, a display instrument and an alarm. The device is connected to the floating roof of the floating roof tank, and can display and forecast the inclination of the floating roof in time, so as to ensure the safe and normal operation of the floating roof tank.
Description
The utility model relates to the floating top rake indication forecast instrument of a kind of unsteady top formula container.It belongs to the parts of the medium-and-large-sized container in Storage Techniques field.
Mostly the floating top (also being called pontoon) of existing unsteady top formula container such as floating roof tank is to be connected to form by top cover, the sealing of lid edge, drainer and floating ladder.Cursory on liquid level in floating withstand on jar, fluctuate with the increase and decrease of liquid stock in the tank body.But floating the withstanding on of existing floating roof tank fallen into foreign matter or floating terraced guide wheel guide rail jam, top cover distortion etc. between in the use because top cover edge and the tank body, can make floating top rake, even cause heavy top or floating top to be damaged, and causes the accident, and influences the normal operation of basin.
The purpose of this utility model provides a kind of floating top rake predictor, in case realize its floating top run-off the straight at floating roof tank, just can show and report to the police, and can in time find, guarantees that floating roof tank safety normally works.
The utility model is achieved in that the floating top rake mechanism for monitoring that device is become by base, middle cover, top cover, spherical pendulum, frequency conversion coil and annular temperature-sensitive resistor group on the top cover on the floating top of floating roof tank, and mechanism for monitoring connects the signal handling equipment that is made of electric balance, amplifying circuit, control circuit, display instrument and annunciator and consists of the floating top rake predictor of floating roof tank.
This utility model is fixed in by its base on the top cover on floating top, covers in the connection base vertical formula spherical pendulum is housed in addition.The top fork of spherical pendulum is with the frequency conversion coil outward, and the end ball of spherical pendulum is surrounded with the quick resistance of annular heat outward, and thermally dependent resistor connects signal handling equipment by cable.Under the normal operation of the floating top of floating roof tank, frequency conversion coil heats spherical pendulum forms metastable temperature field around it.In case floating top run-off the straight, the relative position of spherical pendulum and annular thermally dependent resistor changes, correspondingly the resistance of annular thermally dependent resistor changes thereupon, produce the electric induction signal and be sent to signal handling equipment, measure floating top rake degree value, again by after the amplification filtering processing of circuit through electric balance, pass the signal on the instrument and show, when floating top rake exceeded given value, annunciator was reported to the police, so that in time control and handle.Therefore, quite the prior art advanced person is feasible for the utility model, can in time show and forecast the degree of dip on floating top.Thereby, avoid causing damage and accident, guarantee that floating roof tank normally moves, its novel structure, safe and convenient to use is the floating top rake forecast of an a kind of later-model floating roof tank instrument.
Below in conjunction with drawings and Examples the utility model is described in further detail.
Fig. 1 is the cutaway view of mechanism for monitoring in the utility model.
Fig. 2 be among Fig. 1 A-A to cutaway view.
Fig. 3 is the constructional drawing of induction thermal resistance formula spherical pendulum (4) among Fig. 1.
Fig. 4 is the basic circuit of the utility model signal handling equipment.
With reference to accompanying drawing, the utility model comprises mechanism for monitoring of being made up of base (1), middle cover (7), top cover (9), spherical pendulum (4), frequency conversion coil (5), annular thermally dependent resistor (2) and the signal handling equipment that is connected to form by electric balance, amplifying circuit, display instrument, annunciator.Mechanism for monitoring connects signal handling equipment by its thermally dependent resistor (2) by cable (13).The base of mechanism for monitoring (1) upper flap connects middle cover (7); Spherical pendulum (4) is the central part that the vertical shape is lifted on middle cover (7) by universal ball-collecting rack, spherical pendulum (4) outside ring set frequency conversion coil (5), frequency conversion coil (5) are fixed in the bottom surface of middle cover (7), be surrounded with the quick resistance of annular heat (2) outside the end bob portion of spherical pendulum (4), thermally dependent resistor (2) connects middle cover (7) by location link rod (3); Middle cover (7) upper cap connects top cover (9), and the top of top cover (9) is shaped on stepped hole, in the hole by the cable (13) of seal ring (10) and gland (11) leak-tight joint break-through.
The induction accuracy rate of change of temperature field when guaranteeing that annular thermally dependent resistor moves spherical pendulum, annular thermally dependent resistor (2) is the annular arrangement thermally dependent resistor of being made up of 3-8 piece ring section shape thermally dependent resistor.Spherical pendulum (4) adopts the magnetic liquid suspension technology with being connected of universal ball-collecting rack.Spherical pendulum (4) is connected to form by ball float, fork and bob ball, and universal ball-collecting rack is by ball seat (6) and involutory the connecting to form of spherical cap (8), and the ball float of spherical pendulum (4) is loaded on and becomes universal running-fit to connect in the ball-collecting rack.The spherical cap of universal ball-collecting rack (8) is made by magnetic material, and filling lubricating fluid in the ball-collecting rack rotates flexibly ball float during use.Realize without inverter circuit direct connection power frequency AC for making frequency conversion coil (5), spherical pendulum (4) also may be made in induction thermal resistance formula spherical pendulum (seeing accompanying drawing 3), that is: install induction coil (14) and resistance (16) on the fork body of rod of spherical pendulum (4), resistance (16) connects induction coil (14) by lead (15).Be the protection mechanism inner component, going back cover cap outside the main body that base (1), middle cover (7) and top cover (9) are formed has outer cover (12).
