Description
Technical field
The utility model relates to a kind of warning device, specifically is a kind of wind-driven generator air/water cooler water leakage alarm device.
Background technology
Along with the development of wind-powered electricity generation cause, the aerogenerator air/water cooler is development thereupon also.During work; Air/water cooler places the inlet and outlet of generator top and generator to aim at each other, forms the circulation system of a sealing; Its function is to deliver to refrigeratory to the hot-air that generator produces to advance cooling; Cooled cold air is sent into generator wind through blower fan, makes cold and hot air sealing and circulating exchange, guarantees the generator operate as normal; Generator inside definitely can not intake, in case water inlet, generator insulating destroys, and consequence is hardly imaginable; The heat exchanger of air/water cooler the inside is that the circulation through water comes the inner hot-air of cooled electric generator, so for air/water cooler, it is definitely unallowed leaking; We have settled drip pan below heat exchanger, the pipe that leaks on the drip pan is just in case leak; Just flow out, but the situation of leaking must solve from pipe, how to let not staff at the scene receive the signal that leaks? So a water leakage alarm device must be installed on drip pan; Water leakage alarm device on the market is various in style, but volume is all bigger, and the aerogenerator air/water cooler receives space constraint; Particularly aspect ratio is lower, so the drip pan height below the air/water cooler is also very low, water leakage device has on the market been adorned not; In addition because the temperature of the liquid coolant of refrigeratory at-30 degree ~+60 degree, can not find a suitable not only small and exquisite but also meet the water leakage alarm device that low temperature is used.
The utility model content
The purpose of the utility model is to provide a kind of wind-driven generator air/water cooler water leakage alarm device, and this water leakage alarm device structure is small and exquisite, reliability is high, and dismounting is easy, the characteristics of corrosion-resistant, low temperature resistant and long service life; Have fast detecting, ring the characteristics of celebrating in real time.
For realizing that above-mentioned purpose adopts following technical scheme:
A kind of wind-driven generator air/water cooler water leakage alarm device; Cooperate drip pan to implement; It is characterized in that: it comprises a bridge-type step-down rectifying circuit, and it is the amplifying circuit power supply that the bridge-type step-down rectifying circuit connects a transistor amplifier circuit, the base stage series connection water level sensor of transistor amplifier circuit; Collector at transistor amplifier circuit connects alarm relay, and the control contact string of alarm relay is on warning circuit; Wherein water level sensor is installed in the drip pan, and drip pan is arranged on the below of air/water cooler.
The utility model is mainly restricted according to the aerogenerator inner space, and water level sensor is installed in the drip pan, is used to monitor the water level in the drip pan; Reach alarm water level in case detect the drip pan water level, water level sensor conducting this moment uses transistor saturated; Relay adhesive this moment, output relay signal is reported to the police to warning circuit, and operation technique personnel in time understand situation; The processing of in time being correlated with, after handling well when leaking, water leakage alarm device recovers the supervision state.
Description of drawings
Fig. 1 is the utility model circuit control synoptic diagram.
Embodiment
As shown in Figure 1; A kind of wind-driven generator air/water cooler water leakage alarm device cooperates drip pan to implement, and it comprises a bridge-type step-down rectifying circuit; It is the amplifying circuit power supply that the bridge-type step-down rectifying circuit connects a transistor amplifier circuit; The base stage series connection water level sensor 1 of transistor amplifier circuit, at the collector connection alarm relay 2 of transistor amplifier circuit, the control contact string of alarm relay 2 is on warning circuit; Wherein water level sensor is installed in the drip pan, and drip pan is arranged on the below of air/water cooler.
The operation principle of the utility model is such: the water leakage alarm circuit is inserted the 220V alternating voltage; Reduce the low-voltage DC about rectification output 8V through bridge-type; Low-voltage DC is as transistorized working power; Water level sensor is installed in the drip pan of cooler bottom; In case leak; In drip pan, will produce ponding; When the ponding height reaches the 10MM left and right sides; Water level sensor i.e. the value of having a resistance; Make transistor S9018 saturated through coupler; Relay 2 adhesives, output relay signal alarm; The utility model required water level of reporting to the police is very low, thus in case the condition clearly of leaking just can be reported to the police at once, shortened the leakage time for water treatment, and also water level surpasses the just automatic draining of 10mm, reliability raising.
The utility model structure is small and exquisite, reliability is high; Dismounting is easy, and is corrosion-resistant, the characteristics of low temperature resistant and long service life; And has a fast detecting; Real-time response makes to leak and is reduced to the minimal risk degree, is not only applicable to the aerogenerator air/water cooler, is applicable to that also other has equipment or device that conducting liquid leaks.
