Embodiment

With reference to Fig. 3 to Fig. 4, the embodiment of oil leakage detector is described further.

With reference to Fig. 3 and Fig. 4, oil leakage detector in the present embodiment, comprises matrix (not marking in figure), and matrix has a plane 2 and an outstanding wheel face 1, wheel face 1 is provided with at least two oil leakage sensors 3, and multiple oil leakage sensor 3 evenly is arranged along wheel face 1 week edge; Being provided with processing module (not illustrating in Fig. 3 and Fig. 4) in matrix, processing module is output feedback signal when multiple oil leakage sensor 3 detects that liquid oleaginousness to be measured is too much simultaneously.

Arrange like this, when oil leakage detector tilts to side, the liquid to be measured that at least one placement hole 11 must be caused to enter reduces, even if making the oil leakage sensor 3 at this place also cannot detect when liquid oleaginousness to be measured is too much, only when matrix returns to starting position, oil leakage detector can normally use, and prevents oil leakage sensor 3 flase alarm.

With reference to Fig. 4, the oil leakage sensor 3 in the present embodiment is preferably 3, and 3 described oil leakage sensors 3 evenly are arranged in wheel face 1 week edge.

Arrange like this, 3 sensors are more reliable compared to 2, because when adopting 2 sensors, if matrix is around the straight incline at 2 sensor places, namely 2 sensors are still in identical bits configuration state, now, 2 sensors immunity from interference to external world is substantially identical with 1 sensor, therefore immunity from interference is still not, but 3 sensors solve this problem well, then more cost-saving compared to other quantity.

With reference to Fig. 5 to Fig. 7, being the multiple schematic diagrams comparing unit in processing module, as seen from the figure, what multiple oil leakage sensor 3 connected one to one multiple compares unit. Multiple unit that compares exports when detecting that liquid oleaginousness to be measured is too much with each self-corresponding oil leakage sensor 3 and compares signal (V1��V3).

With reference to Fig. 8, being the schematic diagram of the computing unit in processing module, computing unit is connected with multiple unit that compares. Computing unit receive simultaneously all compare comparison signal (V1��V3) that unit exports time output feedback signal F, wherein, computing unit is and gating circuit.

Arranging like this, can be realized by logic gates, lower compared to micro-chip control cost, control mode is also more simple, does not rely on program.

Wherein, the physical circuit of oil leakage sensor 3 is with reference to the arbitrary width in Fig. 5 to Fig. 7, and oil leakage sensor 3 comprises voltage stabilizing circuit, filtering circuit and Carey-Foster bridge circuit, and voltage stabilizing circuit is used for the voltage of stable output; Filtering circuit is coupled to the voltage that voltage stabilizing circuit receives voltage stabilizing circuit and exports, and exports late-class circuit to after its filtering; Carey-Foster bridge circuit is coupled to filtering circuit receiver voltage, for providing the voltage of respective magnitudes according to the oleaginousness of liquid to be measured to comparing unit.

Arranging like this, voltage stabilizing and filtering can make Carey-Foster bridge circuit electricly stable, take Carey-Foster bridge circuit, can make to export the voltage comparing unit to more stable.

With reference to Fig. 9, as another kind of optimal way of the present embodiment, the wheel face 1 of oil leakage detector being also provided with temperature sensor (not shown), plane 2 is provided with the warning horn (not shown) being connected to temperature sensor; Whether the detected result of liquid level temperature is reported to the police by warning horn according to temperature sensor.

Wherein, temperature alarming technology has been the known technology of those skilled in the art, specifically can see paper " electronic production of temperature buzzer and research ".

Arranging like this, whether the change that temperature sensor can be used for detecting liquid level temperature makes alarm equipment alarm, detects the situation of liquid level for auxiliary oil leakage detector. When temperature jump occurs in liquid level, especially when the phlegma on production line is revealed, can be detected out by oil leakage detector.

The above is only preferred implementation of the present utility model, and protection domain of the present utility model is also not only confined to above-described embodiment, and all technical schemes belonged under the utility model thinking all belong to protection domain of the present utility model. It is noted that for those skilled in the art, in the some improvements and modifications not departed under the utility model principle prerequisite, these improvements and modifications also should be considered as protection domain of the present utility model.
