3, the enrichment pond is a hydrostatic column, diameter 200mm, and high 250mm partly is made up of internal layer, skin, annular spilling water groove, water inlet pipe, rising pipe etc.Internal layer exceeds 1cm with the next door of outer interlayer than outer edge, and has the phase port in the bottom, and the 200-300 mesh filter screen is housed on the phase port.Water inlet pipe diameter 10mm passes skin to internal layer from the enrichment pond, and upward opening.Rising pipe passes the outer oblique downcomer outside to the enrichment pond from internal layer, upper shed diameter 20mm, and the upper shed edge flushes with outer brim height, under shed diameter 10mm.Annular spilling water groove has freeing port.
4, observation pond internal layer, skin and annular spilling water groove etc. are partly formed.The internal layer bottom is a upside down funnel shape, and the bottom maximum gauge is 180mm, and it is 10mm that diameter is the most carefully located at the middle part, the most carefully the place apart from observation the pond at the bottom of 200mm, top is the upper hopper mouth of diameter 80mm, upper hopper mouth edge apart from observation the pond at the bottom of 220mm.Outer diameter 200mm, high 200mm.Observation pond internal layer communicates in the bottom with outer, and the 200-300 mesh filter screen is housed, and outer is annular spilling water groove on every side, and the spilling water groove has the draining mouth of pipe.Bottom, observation pond raises up, and height 100mm is equipped with the LED illuminating lamp.
5, digital micro-analysis camera (containing led light source) is installed in directly over the internal layer of observation pond.
The coboundary that makes water intake during erecting device uses diameter to connect as the 10mm water pipe water intake, self-priming pump, enrichment pond water inlet pipe a little less than the lake water water surface.According to the habit of cercaria in the water surface life, cercaria will flow in the water intake with superficial water, deliver in the internal layer of enrichment pond through self-priming water pump.The water surface life habit of the effect of filter screen and cercaria will make cercaria stay internal layer and concentrate on the surface, and after the water in the enrichment pond is filled, the water that major part does not contain cercaria will spill into the annular spilling water groove from skin, flow back in the lake by freeing port again.Because rising pipe upper shed edge and outer brim height are on the same surface level, and inside and outside two-layer bottom communicate, so the internal layer surface water will carry cercaria and flow out through rising pipe.The water that flows out through rising pipe with the ratio of the water of enrichment pond freeing port discharge is:
only can flow out from rising pipe because of cercaria, thereby can reach the effect of enrichment.
The water delivering orifice of enrichment pond rising pipe places upper hopper mouth top, observation pond.The cercaria of from the enrichment pond, flowing out is slipped into observation pond internal layer along observation pond upper hopper oral-lateral wall, owing to have filter screen and cercaria to have the water surface life habit, cercaria will concentrate on to be observed on the water surface that the pond internal layer the most carefully locates, and water is got back in the lake through annular spilling water groove and drainpipe.Under the illumination of LED lamp, observe, monitor, record a video and take pictures by digital microscope.
Utilize the phototropism of blood fluke cercaria, the top led light source is for often opening, and the led light source of bottom is only opened when needs are taken the record clear pictures.For avoiding blood fluke cercaria to be bonded on the device inwall, device adopts lubricious material (like glass from, stainless steel etc.) to make, and can embrocate the agent of one deck expelling water at device inwall (particularly water surface place).
The invention has the beneficial effects as follows, can realize that whether water field of big area such as lake surface, pond are contained blood fluke cercaria is carried out real-time automatic monitoring, in time find the blood fluke epidemic situation, save a large amount of manpower and materials, improve prevention and cure of schistosomiasis work.
