Abstract

The utility model relates to a fishpond automatic monitor comprising a socket, a shell body and a humidity sensor. The control line of the fishpond automatic monitor is connected with a fishpond automatic aerator. The humidity sensor is equipped on one side of the inner part of the shell body. The other side of the shell body is equipped with an induction system of a certain wave length infrared. The finger of the humidity sensor is made of material that can radiate corresponding wave length infrared. While, the front part of the meter panel of the humidity sensor is sheathed with a rotatable baffle board which can baffle corresponding wave length infrared. Such structure can set the condition of relative air-humidity of automatic starting of the automatic aerator in order to realize unmanned control of 24 hours, which guarantees the safety of fish pond and reduces work intensity greatly, which is also easy in use.

Description

The fish pond automator

Technical field

The utility model relates to the field of fish pond oxygen increasing equipment.

Background technology

The fish pond of propagating artificially, for pursuing maximum economic benefits, the cultivation density in the water is bigger, generally is equipped with aerator in the fish pond for this reason, artificial oxygenation under the lower situation of water oxygen level, the normal growth of assurance fish.Because it is bigger that aerator is opened the back power consumption, people generally just open in the case of necessary, but when, open aerator under which kind of situation, general complete experience with the raiser, for this reason, the raiser must observe, note the situation in the fish pond constantly, find that the symptom of a trend of anoxic or possible situation will manually start aerator at once,, will cause anoxic in the water of fish pond in case error in judgement or delay are opened, fish kill causes serious economy loss.And the experience of reality accumulation shows that there is a kind of relation that links in the oxygen that contains in airborne relative moisture and the fish pond water, and when promptly airborne relative moisture increased, the relative oxygen content in the water of fish pond reduced.

The utility model content

The purpose of this utility model is to overcome passive, the manually operated defective of prior art, utilize the dependency relation of relative air humidity and water oxygen level, a kind of fish pond automator is proposed, make the oxygenation function open or close according to the situation of relative air humidity, realize unmanned in real time monitoring, guarantee safety and the actual effect that culture in the fish pond.

Order of the present utility model is achieved by the following technical solution: the fish pond automator, include base, housing, humidity sensor, its control line is connected with oxygen-enriching machine in fish pond, humidity sensor is loaded on a side in the housing, the opposite side of housing is equipped with certain wavelength infrared induction device, the pointer of humidity sensor adopts the ultrared material of radiation-curable respective wavelength to make, and can stop the ultrared rotatable baffle plate of respective wavelength and the instrument board front of humidity sensor is set with one.Further, baffle plate is semicircular in shape substantially, has fork to stretch out in outside the housing on the baffle plate, and housing has the scale corresponding with the humidity sensor instrument board outward.Also can on the pointer of humidity sensor infrared transmitting device be housed, the opposite side of housing is equipped with infrared receiver.

Such design, utilize the pointer of infrared inductor induction humidity sensor to carry out connecting and disconnecting of the circuit control, people can set the scope of blocking of baffle plate by fork, be the upper limit of setting air relative moisture, in case relative air humidity is too high, pointer exceeds higher limit, pointer just leaves the scope of blocking of baffle plate, make the signal of infrared inductor induction pointer, thereby start aerator, give fish pond oxygenation by control line; If relative air humidity falls back to the following level of capping, pointer is blocked by baffle plate again, and infrared inductor is disconnecting circuit then, and aerator stops.The utility model can be set different air humidity higher limits by fork, be not subjected to the influence of daytime, night or weather condition, can implement unmanned monitoring in real time in 24 hours, safe in utilization, convenient, reliable, both save electric energy, alleviated raiser's labour intensity again.

Embodiment

Referring to Fig. 1-Fig. 3, the fish pond automator of present embodiment mainly by housing 1, be loaded on conventional known certain wavelength of a side in the housing 1 infrared inductor 2, be loaded on the relative humidity sensor 3 of housing 1 interior opposite side and infrared inductor 2, be set in humidity sensor 3 fronts and relatively turnable baffle plate 4, base 5 etc. constitutes, the control line 6 of watch-dog is connected with oxygen-enriching machine in fish pond 7.Wherein, the pointer 31 of humidity sensor 3 adopts the ultrared material of radiation-curable respective wavelength to make, pointer 31 swing on instrument board 32 with the variation of relative air humidity on the one hand, on the other hand with infrared inductor 2 corresponding work, baffle plate 4 is semicircular in shape substantially, employing can stop that the material of respective wavelength infrared penetration makes, and there is a fork 41 to stretch out in outside the chute of housing 1, chute has the scale corresponding with the instrument board 32 of humidity sensor 3 outward, when stirring fork 41, baffle plate 4 just can rotate relative to instrument board 32, and blocks the scope of pointer 31 and instrument board 32 corresponding scales.Transfer at 50 o'clock as fork 41, just baffle plate 4 blocks the scope of relative moisture below 50% that instrument board 32 shows, and the scope of relative moisture 50%-100% is exposed (as shown in Figure 3).Be that setting air relative moisture is higher than 50% o'clock aerator and just starts oxygenation, so analogize that fork 41 was allocated at 80 o'clock, promptly setting air relative moisture is higher than at 80% o'clock and starts aerator.

Its operation principle is: when fork 41 is allocated to 50, baffle plate 4 has blocked pointer 31 and the scope of instrument board relative moisture below 50%, infrared inductor 2 inductions this moment are less than the signal of pointer 31, control line 6 does not have signal, and aerator 7 is static does not work, in case airborne relative moisture was greater than 50% o'clock, pointer 31 just produces the scope of blocking of baffle plate 4, infrared inductor 2 is sensed the infrared signal of pointer 31, so start aerator 7 by control line 6, gives fish pond oxygenation; If the relative moisture of air falls after rise to being lower than 50%, pointer 31 reenters blocking in the scope of baffle plate 4, infrared inductor 2 loss signals, and then deenergization stops aerator 7.The circuit of the foregoing description is conventional known simple control circuit, does not describe here.

Certainly, in addition to the implementation, also can adopt infrared transmitting device is installed on the pointer, the split mode of housing opposite dress infrared receiver produces control signal; Perhaps adopt the signal triggering form of photo resistance, photoelectric tube, can realize that all relative moisture surmounts the control form that starts aerator after the certain limit.The protection domain that this type of is equal to, structure roughly the same, embodiment all should belong to this patent repeats no more here.
