Abstract
本实用新型所述的一种捕获浮游动物的装置涉及一种水处理装置。该装置由水车式增氧机和牵引在其后的浮游动物捕获网组成。本实用新型根据浮游动物漂浮或者游泳能力非常弱的特点，利用养殖池塘水车形成的动力，形成水流，浮游动物在水流的带动下，通过拦截网，进入浮游动物收集器，定期取出收集器中的浮游动物，达到控制水体中浮游动物的目的。本实用新型的有益效果是，通过利用养殖场常被的水车式增氧机形成的动力，自动捕获水中的浮游动物，而且不需要特殊的动力设备。装置的结构简单，还可避免使用化学药物控制浮游动物而带来的药物残留的风险。因此，本实用新型结构简单、流程简短、成本低廉，并且环保无污染。
A device for catching zooplankton described in the utility model relates to a water treatment device. The device is composed of a water wheel aerator and a zooplankton capture net pulled behind it. According to the characteristics of very weak floating or swimming ability of zooplankton, the utility model utilizes the power formed by the water wheel of the breeding pond to form a water flow, and the zooplankton, driven by the water flow, enters the zooplankton collector through the intercepting net and is taken out of the collector regularly zooplankton, to achieve the purpose of controlling zooplankton in the water body. The beneficial effect of the utility model is that the zooplankton in the water can be automatically captured by using the power formed by the waterwheel type aerator often used in the breeding farm, and no special power equipment is needed. The structure of the device is simple, and the risk of drug residue caused by the use of chemical drugs to control zooplankton can also be avoided. Therefore, the utility model has the advantages of simple structure, short process, low cost, environmental protection and no pollution.
Description
[technical field]
The utility model relates to a kind of water treatment device.
[background technology]
Zooplankton is buoyant or the very weak meiofauna of swimming ability, mainly comprises protozoon, rotifers, cladocera and copepods etc., between individual big or small 0.2～3.0 millimeter.Generally wave, constitute planktonic organism with plant plankton along with current.Zooplankton is the same with plant plankton all to be the indispensable natural living baits of fish, and the running balance between plant plankton and the zooplankton is the key of water quality control in the pond culture process in the water body.If but zooplankton forms absolute predominance (being that water body presents oyster white), a large amount of food generate the plant plankton of oxygen, and water quality is reduced, and the mass consumption dissolved oxygen in water, cause fish floating head, the serious floating head, even the general pool; The zooplankton of this moment has become the harmful organism in the water, has influenced the normal growth of fish, causes fish to break out disease.
For this reason, need on the breeding production zooplankton of water body is control effectively.Traditional method mainly contains two kinds, and the one, adopt filter-feeding fish to realize, another is to adopt chemicals (as the crystal Trichlorphon in the agricultural chemicals, chrysanthemum ester class etc.) to kill zooplankton.The former only depends on filter-feeding fish control to be difficult to effective realization because coenocorrelation is subjected to the influence of weather, biomass very big, and the latter then can cause the pond waters coenosis to be seriously damaged, and causes drug residue and environment pollution.
[summary of the invention]
The utility model is intended to overcome defective of the prior art, and a kind of device of catching zooplankton that neither uses chemicals just to reach fully to catch the zooplankton purpose is provided.
The technical scheme that its technical problem that solves the utility model adopts is:
A kind of device of catching zooplankton is by waterwheel aerator be pulled in thereafter zooplankton and catch net and form.
In a preferred examples, zooplankton catches net to be made up of zooplankton interception net and zooplankton collecting net that front and back set gradually, and the aperture of zooplankton interception net is greater than the zooplankton collecting net.
In a preferred example, be provided with plastic float in the described zooplankton collecting net.
In another preferred example, described zooplankton interception net is a wing net sheet.Wherein, preferred net sheet size is 3.0 meters * 5.0 meters.
In another preferred example, described zooplankton collecting net is the cryptomere net.Wherein, preferred net capsule length is 15-20 rice.
In another preferred example, the mesh of described zooplankton interception net is the 40-50 order, and the mesh of zooplankton collecting net is the 150-200 order.
In another preferred examples, the distance that waterwheel aerator and zooplankton catch between the net is a 2.0-2.5 rice.
The utility model is the floating or very weak characteristics of swimming ability according to zooplankton, the power that utilizes the cultivating pool waterwheel to form, form current, zooplankton is under the drive of current, by the interception net, enter the zooplankton collector, regularly take out the zooplankton in the collector, reach the purpose of zooplankton in the control water body.
The beneficial effects of the utility model are by utilizing plant's power of the waterwheel aerator formation of quilt often, to catch the zooplankton in the water automatically, and do not need special power-equipment.Device simple in structure also can avoid using chemicals control zooplankton and the risk of the drug residue that brings.Therefore, the utility model is simple in structure, flow process is brief, with low cost, and environment friendly and pollution-free.
[description of drawings]
Fig. 1 is a structural representation of the present utility model.
[embodiment]
As shown in the figure, a kind of device of catching zooplankton of the present utility model, by waterwheel aerator 1 be pulled in thereafter zooplankton and catch net and forms, the distance between both front and back is a 2.0-2.5 rice.Wherein, zooplankton catches zooplankton interception net 2 and the zooplankton collecting net 3 that net sets gradually by front and back and forms.
Described zooplankton interception net 2 is a wing net sheet.Net sheet size is 3.0 meters * 5.0 meters.The mesh of zooplankton interception net 2 is the 40-50 order.
Described zooplankton collecting net 3 is the cryptomere net.Net capsule length is 15-20 rice.And be provided with plastic float 4 in the zooplankton collecting net 3.The mesh of zooplankton collecting net 3 is the 150-200 order.
During use, at first zooplankton is caught net and be arranged to waterwheel aerator 1 back in the fish pond, open waterwheel aerator 1, make hydrostatic fish pond water flow, the zooplankton insect pest is just constantly driven in the string bag, regularly take insect pest away when the string bag is expired soon, just the zooplankton insect pest can be caught in 2-3 days.
