Technical field
The invention belongs to the water plug that in a kind of aquatic animals and plants culturing pool system, water filtration is processed, specifically be applied in pond, garden, aquarium, aquaculture pond, relate to a kind of driving power that regulates pump according to temperature, to regulate the flow of water, make to there is suitable circulating water flow between culturing pool and water filtration treatment device, thereby have, optionally bring into play physical filtering or biochemistry filtered effect, to reach desirable filtration treatment effect.
Background technique
In prior art, aquatic animals and plants culturing pool system is provided with filtrating equipment and pump, in filtrating equipment, adopt physical filtering and biochemistry filtered water body in system is filtered and processed, to prevent the deterioration of water matter,, by pump, drawn water meanwhile, make water flow to filtrating equipment from culturing pool, flow back to again culturing pool after filtration with after processing, make the water in culturing pool be filtered and process, to improve the effect of filtering and processing.
But practice is found: adopt constant water flow to carry out circulating filtration and processing, the filtering effect of various quarters water quality is different; Further, adopt different water flow to circulate, the filtering effect of water quality is also different.
The temperature in each season is different, temperature has obvious impact for the activity of bacterium, and the existence of bacterium affects generation and the decomposition of material, how to bring into play preferably the effect of physical filtering or biochemistry filtered effect, will directly affect the filtration treatment effect of water quality.
Summary of the invention
The object of the present invention is to provide a kind of water plug that is applied to culturing pool water quality filtration treatment system, this device can regulate according to the variation of water temperature the driving pulse width of pump, pump motor operates on power corresponding to different pulse widths, so that filtration treatment device has suitable flow, thereby can selectively bring into play preferably, physical filtering is processed or the effect of biochemistry filtered processing, filtration treatment effect to increase water quality, prevents water quality deterioration.
Object of the present invention is realized by following scheme:
A kind of water plug that is applied to culturing pool water quality filtration treatment system, comprise power circuit, control and treatment circuit, magnetic polarity testing circuit, drive circuit and pump, wherein, by magnetic polarity testing circuit, the magnetic polarity signal of rotor in pump detected, after treated control circuit computing, export drive control signal, the driving current that meets motor service condition by drive circuit output current polarity, make motor rotation in pump, be characterized in, also comprise a temperature sensing circuit, the temperature that control and treatment circuit detects according to temperature sensing circuit is simultaneously carried out computing, according to following algorithm, regulate the pulse width of drive control signal:
In the scope of 0 ℃～40 ℃ of water temperatures, be divided into two or more temperature sections; At the lower temperature section of temperature, the pulse width of drive control signal is narrower, with less power, obtains less water flow; At the higher temperature section of temperature, the pulse width of drive control signal is wider, with larger power, obtains larger water flow.
Like this, when water temperature is during in the higher temperature section of temperature, biological growth is comparatively active, feed intake many, ight soil is also many, pump work is at high power, can improve the circular flow of water, make physical filtering process performance effect preferably, by food-residue, the organic matters such as ight soil filter out in time, make the liver moss in water, algae and bacterium etc. are filtered and remove because nutriment is accelerated and its breeding is suppressed, harmful bacteria in while water, because nutriment is accelerated, filters and remove, its decomposition nutrition matter and the toxic substance that produces are also suppressed, thereby guarantee that water quality meets the requirements,
When water temperature is during in the lower temperature section of temperature, biological growth is comparatively inactive, feed intake few, ight soil is few, the total amount of organic nutrient substance is less, the breeding of liver moss, algae and bacterium etc. is also slower, harmful bacteria decomposition nutrition matter and the toxic substance that produces is also slower, pump work is in low-power, can reduce the circular flow of water, allow water stop the longer time in filtration treatment device, be conducive to the decomposition of the beneficial bacterias such as nitrifying bacteria to harmful matter, biochemistry filtered performance is acted on preferably, guaranteed that water quality meets the requirements.
The thus obtained water plug that is applied to culturing pool water quality filtration treatment system, can coordinate with the filtration treatment device in system, temperature according to water is that filtration treatment device configures different circulating water flows, and then select the filter type stress, water quality can be met the requirements better, be conducive to prevent the deterioration of water quality.
Water plug of the present invention is in its concrete mode of execution, scope to 0 ℃～40 ℃ of water temperatures is divided into several temperature sections, system carries out according to some responsive temperature reference point T ℃, these temperature spotss all have comparatively significantly impact for vegeto-animal growth conventionally, as 10 ℃, 15 ℃, 18 ℃, 22 ℃, 25 ℃, 30 ℃ etc.
The water plug that is applied to culturing pool water quality filtration treatment system of the present invention, because the temperature according to water is that filtrating equipment configures different circulating water flows, when water temperature is during in the lower temperature section of temperature, adopt less circulating water flow, so, pump work is on compared with the slow-speed of revolution, and the power of its actual consumption is also lower, and this also has very important significance aspect energy-conservation, particularly, corresponding to annual Various Seasonal, in temperature, in those lower seasons, can also save a large amount of power supplys.
Be preferably, in such scheme, the pulse width of drive control signal system regulates according to the actual speed of rotor in pump.Concrete way can be, according to different temperatures, transfer corresponding different rotating speeds, and the set time of rotor rotation half cycle was compared with the time of the actual rotation of rotor half cycle in the corresponding pump of different rotating speeds, according to result relatively, further regulate the increase and decrease of drive control signal pulse width, motor is operated in to be set on rotating speed, to obtain corresponding water flow.
In such scheme, parameter input circlult is housed, and this circuit can be inputted different parameters to control and treatment circuit, so that control and treatment circuit operates in different parameters, to obtain water flow corresponding to multiple different temperature, to meet better different requirements.
In such scheme, in the algorithm of processing control apparatus, adopt return difference algorithm is set near temperature reference point, can avoid when water temperature is near temperature reference point T ℃, due to reasons such as temperature samplings, the working pulse width of pump is frequent transitions between the different gears of two settings.
In such scheme, in the algorithm of processing control apparatus, adopt temperature-averaging value-based algorithm, can make the stability of processing control of temperature sampling and system better.
