Embodiment
Below by embodiment also by reference to the accompanying drawings, the invention will be further described:
As shown in Figure 1, a kind of Ecology comprehensive repair system, primarily of oxygenation aeration system A and animals and plants ecological cultivation system B two portions composition, both are arranged along river course alternate intervals.As Fig. 2, animals and plants ecological cultivation system B comprises the hover D, fish nest E and the ecological fish shelter F that set gradually from top to bottom.
As shown in Figure 3, oxygenation aeration system A is primarily of compositions such as aeration plate C, air supply header 5, gas manifold 6 and air feed shunting disks 7.
Air supply header 5 is lower than gas manifold 6, and air feed shunting disk 7 is higher than gas manifold 6.During actual installation, air feed shunting disk 7 surfaces.Air supply header 5 is arranged perpendicular to river course, and gas manifold 6 is at least two (being separately positioned on both sides, river course), and arranged in parallel along river course.Be communicated with air supply header 5 after the inlet end bending downward vertically of gas manifold 6, the tail end of gas manifold 6 is closed again.
Air feed shunting disk 7 is arranged along the bearing of trend interval of gas manifold 6, and air feed shunting disk 7 is made up of main channel 7a, some isocon 7b of being wholely set with main channel 7a.The upper end closed of main channel 7a, lower end is communicated with gas manifold 6, isocon 7b is the distribution in divergent shape in the circumferential side wall of main channel 7a, each isocon 7b is equipped with a switch 7c, and each isocon 7b is connected with an aeration plate C by an air supply hose 8.
Aeration plate C shown in composition graphs 4-Fig. 6, primarily of aeration plate support and aeration flexible pipe 1 two portions composition.
Aeration plate support is made up of the coil tube bracket 2 be welded and fixed together and annular base 3, and coil tube bracket 2 is welded by the bar steel plate distributed in divergent shape.Preferably, coil tube bracket 2 is that the bar steel plate that distributes of divergent shape is welded " rice " font by the six roots of sensation, certainly, also can select three, four, five or more.
Every root bar steel plate all has some flexible pipe via hole 2a passed through for aeration flexible pipe 1, the tail end of aeration flexible pipe 1 is fixed on the middle part of coil tube bracket 2 after closing, aeration flexible pipe 1, from inside to outside successively through the flexible pipe via hole 2a on coil tube bracket 2, finally forms the aeration coil pipe that spiral-line scatters.The inlet end of aeration flexible pipe 1 is connected with hose nipple 4, and the bearing of trend along aeration flexible pipe 1 has the aerating pore 1a of some spiral-linees distribution; Aerating pore 1a along spiral-line distribution can be row (as shown in Figure 7), is preferably two row and square crossing (as shown in Figure 8).
Annular base 3 is welded by upper annular collar 3a, lower annular collar 3c and some union lever 3b.The diameter of upper annular collar 3a is the half of coil tube bracket 2 diameter, and upper annular collar 3a is welded on the bottom of coil tube bracket 2, the diameter of lower annular collar 3c and coil tube bracket 2 is suitable, the upper end of every root union lever 3b is fixed on annular collar 3a, lower end is fixed on lower annular collar 3c, thus is fixed together by upper annular collar 3a and lower annular collar 3c.
Because the bar steel plate forming coil tube bracket 2 is welded and fixed together by means of only termination, the bottom of coil tube bracket 2 is weldingly fixed in conjunction with upper annular collar 3a, when ensureing that aeration plate is placed under water, coil tube bracket 2 can not be out of shape because of the impact of water and pressure, reduces manufacturing cost to greatest extent simultaneously.
As shown in Figure 9, the hollow hexahedron of ecological fish shelter F to be the cross section surrounded by top board 9, base plate 10, left riser 11, right riser 12, front swash plate 13 and back incline 14 be isosceles trapezoid.Top board 9 has the hole differed in size, complex structure, can strengthen hatching effect, plays good attracting effect.Base plate 10 is arranged at intervals with some planting hole a for planting aquatic plants, planting hole be designed with the growth being beneficial to waterplant, effectively absorb the nutrient laden material in water.Left riser 11 and right riser 12 are provided with arch hole b, sufficiently high arch hole, strengthen the permeability of fish shelter, be conducive to having free passage of fish.Front swash plate 13 and back incline 14 are arranged at intervals with aperture area c, have the hole differed in size in the c of aperture area, rest part d is for adhering to planktonic organism.The hole differed in size arranged in aperture area, the wadding stream of generation is conducive to the gathering absorbing fish, and being designed with of aperture is beneficial to small fish and hides catching up with of large fish; Rest part is for adhering to planktonic organism, and more bond area, for fish provides abundant bait, is more conducive to the improvement of water surrounding simultaneously.
Figure 10 shows that the fluidised form figure that echelon form ecological fish shelter is formed, Tu10Zhong, 1 is slough, and 2 is recirculating zone, 3 is slight vortex cavity, and 4 is air-flow acceleration zone, and 5 is stalling point, and 6 is fish shelter top stream rising area, 7 is slough, and 8 is vortex cavity, and 9 is eddy current, and 10 is area of slack water in fish shelter body.
