Description
Technical field
The utility model relates to a kind of ecosystem characterization and hydraulic characteristic(s) that fully utilizes oncomelania and removes spiral shell, thereby realizes the small water conservancy device of prevention and cure of schistosomiasis.
Background technology
China is one of schistosomiasis country all the fashion.By 2007, the whole nation had 449 schistosomiasis endemic counties (city, district), blood fluke patient 515971 people.Oncomelania is as the unique vector of blood fluke, eliminates oncomelania in the water and be the basic method of prevention and cure of schistosomiasis on the root.China mainly removes the spiral shell method at present has snail control with drugs method, block method, snail sedimentation tank technology law, middle layer water withdrawal method and channel hardening process.But all have not ecological, environmental protective, resistance effect is obvious, defectives such as heavy spiral shell poor effect.
The utility model content
A kind of efficient green that provides in order to solve the prior art deficiency is removed the oncomelania in the irrigation draught engineering, thereby the ecological waterpower of purpose that reaches effective prevention and cure of schistosomiasis is comprehensively removed the spiral shell device.
The technical scheme that the utility model adopts:
A kind of ecological waterpower is comprehensively removed the spiral shell device, and it comprises the shaped form bobbin, and bobbin one end is provided with water inlet pipe; Water inlet pipe is obliquely installed, and the other end is provided with the V-type delivery port, and the bobbin middle part is provided with the secondary diffusion barrier; Had aquaporin on the secondary diffusion barrier; The non-passage of secondary diffusion barrier place is provided with solar energy ruddiness equipment, and the bobbin bottom is an inclined floor, the downward to the right respectively inclined in two-way of inclined floor; Inclined floor has two Archimedes and arranges screwed pipe, and two Archimedes arrange the lowest part that screwed pipe lays respectively at the inclined floor of secondary diffusion barrier both sides.
Above-mentioned water inlet pipe is downward 45 ° of inclined in two-way to the right, and Parallel to the flow direction is seen, is arranged at the left side, axis.
Above-mentioned spool upper end is provided with two escape tube of funnel type, and two escape tube lay respectively at secondary diffusion barrier both sides.
The technique effect that the utility model is obtained:
1, the utility model ecosystem characterization and hydraulic characteristic(s) of taking into full account oncomelania removed spiral shell, and simple in structure, easy construction need not block, also need not to use snail control with drugs, green non-pollution, and it is high to remove spiral shell efficient; In addition can be according to actual conditions local adjustment device shape and size, thus various different feed ditch be applicable to, to ensure the productive life water safety, promotional value is widely arranged; After the oncomelania of collecting is pulverized, can make the poultry feed, have obvious social and economic benefit.

Embodiment
Below in conjunction with accompanying drawing the embodiment of the utility model is done further explanation.
Referring to Fig. 1-5, a kind of ecological waterpower is comprehensively removed the spiral shell device, and it comprises shaped form bobbin 2; Bobbin one end is provided with water inlet pipe 1, and water inlet pipe is obliquely installed, and the other end is provided with V-type delivery port 4; The bobbin middle part is provided with secondary diffusion barrier 8, has aquaporin 9 on the secondary diffusion barrier, and the non-passage of secondary diffusion barrier place is provided with solar energy ruddiness equipment 3; The bobbin bottom is an inclined floor 5; Inclined floor is inclined in two-way downwards to the right respectively, and inclined floor has two Archimedes and arranges 6, two Archimedes of screwed pipe and arrange the lowest part that screwed pipe lays respectively at the inclined floor of secondary diffusion barrier both sides.Described water inlet pipe is downward 45 ° of inclined in two-way to the right, and Parallel to the flow direction is seen, is arranged at the left side, axis.Said spool upper end is provided with two 7, two escape tube of escape tube of falling funnel type and lays respectively at secondary diffusion barrier both sides.
The Bian Bike of above-mentioned water inlet pipe, shaped form bobbin regulates angle of inclination and degree of crook according to the concrete condition of different channels; Guarantee water inlet pipe downwarping to the right; Produce jet to the bottom of shaped form convex bank, so that form the backflow of suitable oncomelania sedimentation in the porch.
The shape of above-mentioned V-type delivery port and big I adjust the degree of going deep into and the height at the mouth of a river according to actual conditions, and its effect is to form in the left and right sides in exit to reflux, and makes oncomelania obtain sedimentation again, prevent that the young spiral shell that gets into the second half section from escaping from device.
Above-mentioned secondary diffusion barrier is for oncomelania is carried out after-treatment.The Luo Kan that blocks through arranging on it makes oncomelania just obtain sedimentation at preceding half section as much as possible.And after current passed through aquaporin, because the secondary of the cross-section of river enlarges, the reduction of flow velocity and the change of fluidised form obtained sedimentation once more with the young spiral shell that makes minority get into the second half section.
The downward to the right inclined in two-way of above-mentioned inclined floor.Right side, the upper reaches flow rate of water flow of inflow direction is minimum, and the most suitable debris buildup is so the downward-sloping to the right position of this flow velocity lowest part that makes of inclined floor also is in minimum.Its inclined degree can be adjusted according to actual conditions.
The ecosystem characterization of above-mentioned solar energy ruddiness equipment utilization oncomelania, major part can be closed operculum and come off when it runs into light intensity and surpasses the ruddiness of 4000lx, moves with water movement or to the backlight direction.
Above-mentioned " escape " pipe utilizes the ecosystem characterization of oncomelania, and oncomelania was difficult to existence when the depth of water surpassed 3m, can initiatively move to low-pressure area.Be embedded in underground device and have bigger water pressure, can make the oncomelania of part sedimentation lean on self strength " to escape from " device, thereby reclaim, alleviate row's screwed pipe and load.
Above-mentioned Archimedes arranges the lowest part that screwed pipe is arranged at the inclined floor of secondary diffusion barrier both sides.Can be easily with the rotation of the oncomelania of sedimentation in the device, gathering through helicoid, directly drain into ground from being embedded in underground lower, concentrate recycling again.Avoid the too much blocking device of oncomelania accumulation because of sedimentation.
The protection domain of the utility model is not limited to the above embodiments, and obviously, those skilled in the art can carry out various changes and distortion and not break away from the scope and the spirit of the utility model the utility model.If these changes and distortion belong in the scope of the utility model claim and equivalent technologies thereof, then the intention of the utility model also comprises these changes and is out of shape interior.
