Abstract

Proposed is a cartridge for a leak detection sensor. The cartridge includes a housing having an inner side thereof provided with a mounting space portion in which a reaction material is mounted, the housing having a plurality of fluid moving grooves in which a leaked oil is capable of being moved toward the reaction material and which is formed around an opening portion of a lower portion of the housing by a predetermined distance. Furthermore, the cartridge includes the reaction material being an opaque material, the reaction material being configured to be converted to a transparent state when the reaction material absorbs oil and reacts with an absorbed oil, and includes a separation prevention plate mounted by being fitted into the opening portion of the housing, the separation prevention plate preventing a separation of the reaction material that is mounted by being fitted into the fluid moving grooves.

Description

CROSS REFERENCE TO RELATED APPLICATION The present application claims priority to Korean Patent Application No. 10-2022-0165575, filed Dec. 1, 2022, the entire contents of which are incorporated herein for all purposes by this reference. BACKGROUND OF THE INVENTION Field of the Invention The present disclosure relates to a cartridge for a leak detection sensor. More particularly, the present disclosure relates to a cartridge for a leak detection sensor, the entire of the cartridge being capable of being conveniently replaced and mounted at the leak detection sensor after leak detection is performed, the cartridge being configured such that the cartridge is in an opaque state when oil is not absorbed to the cartridge and the cartridge is converted to a transparent state when the cartridge absorbs oil and reacts with the absorbed oil so that leak detection is capable of being performed, and the cartridge being capable of being used by replacing a reaction material only. Description of the Related Art Generally, various types of leak sensors for detecting a water leakage and an oil leakage are used in a water leakage situation and an oil leakage situation. As representative leak sensors, a cable-type leak sensor, a band-type leak sensor, and a module-type leak sensor are used. The cable-type leak sensor is a leak detection sensor which detects the exposure of various liquids (water, oil, and so on) and which accurately and rapidly informs of a point where a liquid leakage occurs. The water leakage and the oil leakage may be checked by detecting a potential difference of an electric current that flows along a conducting wire, the potential difference being generated by a resistance of water or oil that are leaked, and the potential difference can be detected using a detection line. In such a band-type leak detection sensor, when water contacts an electric wire while a current flows through the electric wire, a resistance value of the electric wire is changed, so that whether a water leakage occurs is capable of being detected by checking the resistance value that is changed. Such a band-type leak detection sensor can detect a water leakage in a large area at low costs and is easily mounted. However, there is a problem that the band-type leak detection sensor is required to be replaced after a single use. Meanwhile, in the module-type leak sensor, photo sensors (a light-receiving portion and a light-emitting portion) are positioned inside a plastic casing. Furthermore, a beam of the light-emitting portion is received by the light-receiving portion when liquid is not detected, but the beam does not go to the light-receiving portion due to a change of a refractive index when the liquid is detected by the beam of the light-emitting portion, so that a water leakage is detected on the basis of a received state of light. Such a module-type leak sensor can detect a change in the amount of light emitted by the light emitting portion, the change being caused by a leaked liquid, so that whether a leakage occurs is capable of being easily and conveniently measured. However, there is a disadvantage that the module-type leak sensor cannot be used only for detecting a leakage of specific liquid since the module-type leak sensor is configured to detect the occurrence of a leakage of all kinds of liquids.
