The inlet shaft of the transmission mechanism is connected with the floating ball, and the outlet shaft is connected with the finger. A potentiometer comprises a resistance wire and a sliding piece cooperating with the resistance wire. The sliding piece and the finger are synchronous linkage. The output signal of the potentiometer is connected with a remote computer through a converter; the transmission mechanism is provided with an installation base, and the potentiometer is sealed in the installation base. Voltage signal from the potentiometer in the float liquid level meter is transmitted to the computer system in the central control room through a module virgule digital converter and then telephone line, displaying the rest amount of liquefied petroleum gas in each user's storage tank so as to determine the filling time of each user's liquefied petroleum gas.
Description
(1) technical field
The utility model relates to a kind of floater type liquid level gauge for liquefied petroleum gas storage tank.
(2) background technology
Civil LPG (being called for short LPG) adopts the novel air supply system of a family one storage tank, wherein liquefied petroleum gas storage tank is topmost equipment, and one of critical component in this equipment is a float type level gauge, and it shows the actual capacity of liquefied petroleum gas (LPG) in the storage tank by pointer.When storage tank filled liquefied gas, the pointer of float type level gauge can show the actual capacity of liquefied petroleum gas (LPG) variation in the storage tank in the filling process exactly, with carrying out smoothly of guaranteeing to fill at lng tanker.In user's use, the volume change one of liquefied petroleum gas (LPG) is that pointer by float type level gauge shows on the spot in the storage tank.But the shortcoming that this structure exists is: can only the field observation of single family, can't realize remote control.
(3) summary of the invention
The purpose of this utility model provides the floater type liquid level gauge for liquefied petroleum gas storage tank simple in structure of the long-range understanding petroleum gas of a kind of energy volume change for solving the shortcoming of the volume change that existing floater type liquid level gauge for liquefied petroleum gas storage tank can only field observation petroleum gas.
For this reason, the utility model is by the following technical solutions:
A kind of floater type liquid level gauge for liquefied petroleum gas storage tank, include ball float, gear train, indication panel, be installed in the pointer on the panel, the top input shaft of gear train is connected with ball float, the terminal output shaft of gear train is connected with pointer, also include potentiometer, the sliding sheet that described potentiometer includes resistance wire, cooperates with resistance wire, described sliding sheet and pointer are synchronous interaction, and the output signal of potentiometer connects remote computer by converter; Described gear train is provided with mount pad, and described potentiometer sealing is installed in the described mount pad.
The change in resistance of described resistance wire and the pointer on the panel rotate and are complementary.
Described ball float is the hollow structure of metal material.
Also include the structure of removing obstacles that is installed in the pedestal, the described structure of removing obstacles includes: straight-tooth gear, straight-tooth gear axle, axle sleeve, described axle sleeve outer end is provided with spiro cap, between described straight-tooth gear axle, the axle sleeve spring is arranged, the gearing mesh of described straight-tooth gear and gear train.
The beneficial effect of floater type liquid level gauge for liquefied petroleum gas storage tank described in the utility model is mainly reflected in: voltage signal that 1, potentiometer spreads out of in the float type level gauge is through mould/number conversion (converter), be transferred to the computer system of central control room again by telephone wire, the surplus of liquefied petroleum gas (LPG) in each user's storage tank of centralized displaying, thus determine filling the time of each user's liquefied petroleum gas (LPG); 2, float adopts the hollow ellipsoid of particulate metal material, can long period of soaking can not increase weight or loss of weight in LPG, makes float float on liquid level all the time, thereby guarantees the accuracy of liquid level gauge; 3, the mechanism that removes obstacles efficiently solves when meshed bevel gears can't be rotated because of reasons such as impurity are stuck, the shortcoming that the variation of liquid level can't show, the way of specifically removing obstacles is as follows: back out spiro cap 18, push down axle sleeve 17 to overcome spring force 16, straight-tooth gear axle 15 is put in inwards, gear 14,6 engagements.At this moment, rotary axle box 17 rotates straight-tooth gear axle 15, gear 14, and by engagement, gear 6 rotates, and drives transmission shaft 5 and rotates, thereby bevel gear 3, semi-finals row are rotated, and fork 2 is swung around center line I-I; In like manner, back and forth rotary axle box 17 makes bevel gear 3, semi-finals row come back rotation, and fork 2 swings back and forth around center line I-I, thereby makes bevel gear 3,4, and fork 2 rotates flexibly.Loosen axle sleeve 17, gear 14,6 promptly breaks away from engagement, float type level gauge operate as normal.

(5) embodiment
Below in conjunction with specific embodiment the utility model is described further:
With reference to accompanying drawing 1,2, a kind of floater type liquid level gauge for liquefied petroleum gas storage tank includes ball float 1, (described gear train includes gear train: fork 2, bevel gear 3,4, transmission shaft 5, gear 6, circular magnet steel 7,8, minor axis 9; ), indication panel 11, be installed in the pointer 12 on the panel, the top input shaft of gear train (fork 2) is connected with ball float, the terminal output shaft of gear train (minor axis 9) drives magnet steel 7 and rotates, and utilize polarity that magnet steel 8 is rotated synchronously, magnet steel 8 is connected with pointer, also include potentiometer 10, the sliding sheet 102 that described potentiometer includes resistance wire 101, cooperates with resistance wire, described sliding sheet and pointer are synchronous interaction, and the output signal of potentiometer connects remote computer 104 by converter 103; Described gear train is provided with mount pad 13, and described potentiometer sealing is installed in the described mount pad.The change in resistance of described resistance wire and the pointer on the panel rotate and are complementary.Described ball float is the hollow structure of stainless steel material.Described float type level gauge also includes the structure of removing obstacles that is installed in the pedestal, the described structure of removing obstacles includes: straight-tooth gear 14, straight-tooth gear axle 15, axle sleeve 17, described axle sleeve outer end is provided with spiro cap 18, there is spring 16 on the top between described straight-tooth gear axle, the axle sleeve, and straight-tooth gear 14 meshes with the gear 6 of gear train.
