Should be appreciated that specific embodiment described herein only in order to explaining the utility model, and be not used in restriction the utility model.
With reference to Fig. 1 and Fig. 2, Fig. 1 is the leak front view of structural representation of detector one embodiment of the utility model fixed-point type; Fig. 2 is the upward view of structure among Fig. 1; The utility model provides a kind of fixed-point type detector that leaks, and comprising:
The described fixed-point type detector that leaks is the water resistance structure of totally-enclosed encapsulation, and its housing 10 adopts PVC materials, its material environmental protection, and can effectively prevent the interference to process chip that static etc. brings.The described fixed-point type inner probe that arranges 30 of detector that leaks is dome-type, and adopts the gapless sealing to be connected with described housing 10.When water droplet touched described probe 30, the described fixed-point type detector that leaks utilized optical principle, and by a series of calculating of its process chip 20, the output signal of warning reaches the purpose of leaking and detecting.The described fixed-point type detector outward appearance of leaking is UFO-like, and volume is little and attractive in appearance, and is easy for installation.
As shown in Figures 1 and 2, described base 102 is provided with a recess 1021, and described probe 30 is placed in described recess 1021, and sinks into described recess 1021 in the described probe 30, keeps a fixed gap with described base 102 away from an end face of described holding part 101.Described probe 30 caves in, and makes 30 to aim at control surfaces and described fixed-point type is installed when leaking detector will popping one's head in, and can effectively reduce because of weight, draw to decrease to destroy and pop one's head in 30.
Further, the described fixed-point type detector that leaks comprises that also its power lead is connected with process chip by described wire hole 40 with signal wire for the wire hole 40 that draws power lead and signal wire in.Described wire hole 40 is arranged at a side of described holding part 101.Adopt the mode that is tightly connected between the power lead of described wire hole 40 and its gathering and the signal wire, when there is water droplet following time the leak top of detector of described fixed-point type, the top arranges the mode of wire hole 40 relatively, the mode of wire hole 40 is offered in the side of described holding part 101, can effectively reduce water droplet for the influence of the Seal Design of described wire hole 40.
Further, described base 102 comprises for the leak pilot hole 1022 of detector of the described fixed-point type in location.Described pilot hole 1022 is threaded hole.The detector two ends that leak of fixed-point type described in the present embodiment are respectively equipped with threaded hole, with convenient the described fixed-point type detector that leaks are fixed on the plane of different surveyed areas.
Further, described base 102 is provided with a positioning block 1023 corresponding to described pilot hole 1022 positions, and described locating piece 1023 is arranged at described base 102 away from an end face of described holding part 101.Described locating piece 1023 makes has certain slit between described probe 30 and the control surface, to make things convenient for the infiltration of water.The described fixed-point type detector that leaks is easy for installation, can utilize the general knowledge that Water seeks its own level, and the described fixed-point type detector that leaks is installed in the lowermost portion of whole guarded region, and uses described pilot hole 1022 to be fixed to get final product.The described fixed-point type of the present embodiment detector height that leaks is 18mm, and the locating piece 1023 of wherein said base 102 highly is 2mm, and described base 102 highly is 3mm, and described holding part 101 highly is 13mm, and the described fixed-point type detector the widest part that leaks is 50mm.
With reference to Fig. 3, Fig. 3 is the leak probe one embodiment synoptic diagram of detector of the utility model fixed-point type.Described probe 30 is actually a photoelectric sensor, realizes control by the variation that the variation of light intensity is converted to electric signal.Comprise for the transmitter 301 that sends light wave, be used for the described light wave of reflection deflecting plate 302, be used for receiving the light wave after the reflection receiver 303, connect described receiver 303 and for detection of the testing circuit 304 of the accepting state of described receiver 303, described transmitter 301 and receiver 303 are arranged at described deflecting plate 302 the same sides.Fixed-point type of the present utility model leak detector by receiver 303 under normal circumstances the light wave that sends of receiver transmitter 301 to keep normal condition, and when having liquid, deflecting plate 302 surface coverage can't receive light wave and output switching signal, so, whether can in time detect has leak of liquid, and its detection sensitivity height, flexible for installation, volume is little.Concrete, the light wave that described transmitter 301 sends derives from light emitting diode, and under the normal condition, the light wave that described transmitter 301 sends is reflected by described deflecting plate 302, and is accepted by described receiver 303; And in case described deflecting plate 302 surface coverage one deck refractive indexes are in certain medium between air and the described deflecting plate 302, during such as water droplet, the light wave that described transmitter 301 sends just can see through this layer medium makes its light path change, no longer accepted by described receiver 303, state testing circuit 304 and detect this variation this moment, and export a switching signal, after handling by described process chip 20, send alarm signal.
The described fixed-point type detector that leaks also comprises be used to the warning device (not shown) of warning.Described process chip 20 is by power lead and direct-connected power supply and the described warning device of connecing of signal wire.Described fixed-point type leaks the detector monitors zone extensively, not only can monitor plane, pipeline, can also monitor valve, corner.
When described fixed-point type leaks detector work, need to select earlier a flat surface, and make its probe 30 towards the plane of needs monitoring.The self-tapping screw that is about 10-15mm by two length of threaded hole location and installation.Because locating piece 1023 is 2mm highly, and sink into the recess 1021 of described base 101 in the described probe 30.Therefore when seepage, current are flow direction probe 30 easily, and triggers and report to the police.The described fixed-point type detector that leaks can detect in time whether leak of liquid is arranged, and its detection sensitivity height, flexible for installation, volume is little, good water-proof effect.
The above only is preferred embodiment of the present utility model; be not so limit claim of the present utility model; every equivalent structure or equivalent flow process conversion that utilizes the utility model instructions and accompanying drawing content to do; or directly or indirectly be used in other relevant technical fields, all in like manner be included in the scope of patent protection of the present utility model.
