Detachable throw-in type liquid transmitter

Abstract

The invention provides a detachable throw-in type liquid transmitter, comprising a base, a front sleeve, waterproof rubber rings, a middle sleeve, a male joint, a locking ring, a female joint, a back sleeve, an electric wire signal chuck, a gasket and a pressing nut. The base is threadedly connected the front sleeve, the front sleeve is threadedly connected the middle sleeve, and the male joint is threadedly connected the female joint; the locking ring is located on the outer walls of the male joint and the female joint and locks the male joint and the female joint; the electric wire signal chuck is arranged in the head of the back sleeve; the pressing nut is threadedly connected the back sleeve; the waterproof rubber rings are respectively arranged between the base and the front sleeve, between the front sleeve and the middle sleeve, between the middle sleeve and the male joint, between the male joint and the locking ring, between the female joint and the back sleeve, between the back sleeve and the electric wire signal chuck, and between the electric wire signal chuck and the pressing nut; the size of each waterproof rubber ring is matched with the size of ports where the waterproof rubber rings are located; the corresponding gaskets are respectively arranged between the locking ring and the female joint, and between the back sleeve and the pressing nut; an electric wire passes through the back sleeve through an electric wire signal inclined joint which is arranged on the male joint and then passes through from the electric wire signal chuck; and an assorted sensor and a circuit board are fixedly arranged in the middle sleeve. The detachable throw-in type liquid transmitter provided by the invention has practical values.

Description

technical field [0001] The invention relates to a detachable waterproof joint, in particular to a detachable drop-in liquid level transmitter. It is a detachable waterproof joint used for sensor supplies working in liquid, and belongs to the technical field of liquid level measuring equipment. Background technique [0002] At present, domestic input-type liquid level transmitters used to measure liquid levels are all integrated, that is, liquid level acquisition probes and transmission cables are integrated. Due to the long-term immersion in the liquid for liquid level measurement, especially when the liquid level is very deep, there are two main parts that affect the life of the input liquid level transmitter: one is that the signal line is easily broken, and the other is that the integrated input The liquid level transmitter has a short life span, generally only 2-3 years, which makes it necessary to replace the liquid level transmitter from time to time in actual enginee...

Problems solved by technology

Due to the long-term immersion in the liquid for liquid level measurement, especially when the liquid level is very deep, there are two main parts that affect the life of the input liquid level transmitter: one is that the signal line is easily broken, and the other is that the integrated input Type liquid level transmitter has a short service life, generally only 2-3 years, which makes it necessary to replace the liquid level transmitter from time to time in actual engineering

However, it is generally impossible to replace the probe or the power cord on site, and it is extremely difficult to repair the probe after returning, and it is impossible to guarantee the sealing and reliability of the liquid level transmitter after the probe is replaced, which brings great benefits to the actual engineering operation and liquid level research. Difficulties and many inconveniences; especially when there are many monitoring points and a wide monitoring area, it needs to consume huge manpower and material resources, resulting in a great waste of engineering
