The invention relates to an ecological repairing method of eutrophicated water bodies in rivers and lakes and sediments, and provides a construction method of an organism structural system for synchronously repairing eutrophicated water bodies in rivers and lakes and sediments in situ by means of emergent aquatic plants, submerged plants, benthonic animals, fishes and microorganisms. The light enhancing oxygen-enriched organism structural system for synchronously repairing eutrophicated water bodies in rivers and lakes and sediments in situ has the double effects of synchronously and ecologically repairing polluted water bodies and sediments and providing habitats for aquatic organisms and microorganisms. The system comprises a lens reflective light enhancing surface water emergent aquatic plant survival area, a hollow prismoid free sliding middle water purifying area, a sediment-water interface submerged plant, a benthonic animal and fish survival area, a microorganism enriched intensified sediment purifying area and an oxygen-enriching fixed rod. The system provided by the invention can synchronously and ecologically repair the water bodies and the surface sediments, has the characteristics of good pollutant removing effect, stable and lasting treatment effect and the like, and is suitable for synchronously repairing water bodies in rivers and lakes and sediments in situ.

The invention discloses an anti-blocking method applicable to a circulation water loach breeding pond bottom drain. The anti-blocking method comprises the steps of arranging a sewage cleaning machine in a gap of escape-proof fences of a sewage draining machine and enabling scraping teeth protruded out of the periphery of the sewage cleaning machine to be embedded with gaps of the fences of the sewage draining machine one by one; connecting a guide rod which is welded with the center of the sewage cleaning machine and straightly led to the water surface and a connection rod to a motor which is arranged at the top end of a main frame; and dragging the guide rod and the connection rod through the motor to enable the sewage cleaning machine to move up and down, automatically clean blockage substances and retain smooth water drainage and normal circulation. The anti-blocking method applicable to the circulation water loach breeding pond bottom drain is applicable to industrial circulation water breeding of small varieties comprising loach and suitable for cleaning sediments which block water drain gaps of the bottom drain; and through the method, the anti-blocking problem of the sewage draining machine in small fish circulation water breeding can be effectively solved. The method is simple; devices are convenient to mount and manage; the sewage cleaning machine and a raw sewage draining device are only required to be matched and fixed wholly; the devices are capable of automatically operating and saving labor; and the device are excellent in economy and practicability.

In the X-shaped elastic support structure of the connector with socket in the present invention, an insertion hole is arranged in the middle of the connector cover plate of the connector, and an insulating seat is arranged inside the insertion hole, and the two conductive row ends of each layer of conductor connecting piece extend out of the insulating partition The pin groove is formed above the upper edge, and the X-shaped elastic body whose main body is a rubber composite shrapnel is supported in the space between the connecting pieces of the conductors of each phase, so that the conductive row of the connecting pieces of the conductors of each phase can clamp the pins of the plug-in box and improve the plug-in connection. Contact conductivity; and a U-shaped clip is set on the outermost conductor connecting piece to assist in clamping the two conductive rows of the outermost conductor connecting piece, further improving the electrical conductivity of the plug-in contact, the assembly operation is simple, the shunt current performance is stable and reliable, and can reduce The number of connectors and socket parts is small, and the packaging, transportation, installation, management and operation are convenient.
