Abstract
The utility model discloses a tank bottom fixing structure of a liquid level sensor, which comprises a galvanized steel sleeve, a magnetic steel body, non-magnetic alloy jaws and an oil-resistant plastic sleeve, wherein a shielding cavity is arranged at the lower part of the galvanized steel sleeve, and a connecting part is arranged at the upper part of the galvanized steel sleeve; the magnetic steel body is arranged in the shielding cavity, and the oil-resistant plastic sleeve is arranged at the opening at the lower part of the shielding cavity; and the bases of the non-magnetic alloy jaws are positioned at one side of the shielding cavity, the jaw tips pass through the oil-resistant plastic sleeve, and one section of the jaw tip projects out of the oil-resistant plastic sleeve; and whenbeing vertically arranged, the liquid level sensor is fixedly connected with the tank bottom fixing structure through the bottom of the sensor. The utility model is positioned between the sensor and the tank bottom, and can generate a strong magnetic force attracting the tank bottom in the single direction; the non-magnetic alloy jaws are directly inserted in the steel plate of the tank bottom bythe strong magnetic force and the self-weight of the liquid level sensor, so that the impact force generated in the process of oil unloading can not cause the position deviation of the liquid level sensor, thereby being particularly favorable for ensuring the measurement accuracy of the liquid level sensor.
Description
Technical field
The utility model relates to liquid level sensor, and is relevant with the fixed sturcture (device) at jar end (container bottom) with liquid level sensor especially.
Background technology
At present, known liquid level sensor adopts vertical mounting means mostly, as magnetostrictive liquid level sensor wherein.Magnetostrictive liquid level sensor is directly put into the standpipe of liquid medium containers such as oil tank, because it is available that liquid level sensor and jar still do not have fixed sturcture (device) at the end, the liquid level sensor bottom directly contacts with a jar end but can't fix, the refuelling station can produce bigger impulsive force in the emptying process, this impulsive force is very big to the influence of liquid level sensor original position, even can cause the liquid level sensor position to be offset, cause the actual level height of liquid level sensor measuring height and oil tank that bigger error is arranged, under indivedual serious situations between the two error reach 5～10mm unexpectedly, have a strong impact on the oil metering business of refuelling station.This problem of ubiquity in the same industry, the user is also relatively stronger to this problem reflection.
The utility model content
The utility model is to solve the above-mentioned technological deficiency that prior art exists, and a kind of jar end fixed sturcture of liquid level sensor is provided.
Its technical solution is:
A kind of jar end fixed sturcture of liquid level sensor, comprise galvanized steel jacket, magnet steel body, nonmagnetic alloy claw and oil resistant plastics cover, the bottom of galvanized steel jacket is provided with shielding cavity, top is provided with connection part, the magnet steel body is arranged in the shielding cavity, oil resistant plastics is set on the opening port place, below of shielding cavity, and the pawl base portion of nonmagnetic alloy claw is positioned at shielding cavity one side, and hook tip passes the oil resistant plastics cover and gives prominence to one section.
Above-mentioned connection part is the connection part of detachable connecting mode.
Above-mentioned nonmagnetic alloy claw global approximation T type.
The top of above-mentioned galvanized steel jacket is contraction section, and the bottom is an expansion segment, is provided with the one section blind hole that has internal thread that stretches vertically in contraction section, and shielding cavity is arranged in the expansion segment, and the oil resistant plastics cover is nested with and is fixed on the expansion segment.
Above-mentioned nonmagnetic alloy claw is three, equiblibrium mass distribution on same circumferencial direction.
The pawl base of above-mentioned nonmagnetic alloy claw contacts with the magnet steel body.
The inboard of above-mentioned oil resistant plastics cover is provided with the pawl foundation trench, and the pawl base portion of nonmagnetic alloy claw is positioned at corresponding pawl foundation trench, and the inboard central part of oil resistant plastics cover is a teat, and this teat contacts with the magnet steel body.
The beneficial effects of the utility model are:
In the vertical installation process of liquid level sensors such as magnetostrictive liquid level sensor, bottom and the utility model by liquid level sensor are fixedly connected, the utility model at liquid level sensor and at jar the end, its can produce folk prescription to the strong magnetic force that attracts mutually at the bottom of the jar, nonmagnetic alloy claw is by its hook tip, by strong magnetic force and liquid level sensor self gravitation straight cutting on the steel plate at the bottom of the jar, the impulsive force that is produced in the process of emptying can not cause or can not cause liquid level sensor to produce offset easily like this, is particularly conducive to the measuring accuracy that guarantees liquid level sensor.
