By the way, in the inland sea that receives water flowing out from urban lakes, rivers, and the like, an oxygen-deficient state in which an anoxic water mass is generated in the seabed area (depth 15 to 20 m) in summer when the temperature is high. When the city's domestic wastewater contains nitrogen, phosphorus, etc., it flows from the river into the inland sea and becomes eutrophied, and when the phytoplankton that is generated in large quantities due to the rise in water temperature falls as a dead body It is said that this oxygen deficiency occurs by consuming oxygen in the sea water when bacteria decompose it. If it becomes oxygen deficient, shellfish that live on the sea bottom will not be able to breathe and die, algae disappear, fish disappear, and blue tide is generated by sulfide contained in the water mass, and sulfide floating on the sea surface is coastal There are many examples of damage, such as accelerating the deterioration of buildings and sludge deposited on the sea floor becoming a source of harmful substances.

  A rod 26 projecting from the upper plate 24 onto the cylinder body 11 is erected, and this rod 26 is rotatably connected to the base portion of the interlocking lever 27. An intermediate point of the interlocking lever 27 is rotatably supported on the upper end of the support arm 18. A partition plate 28 and a vertically movable spring plate 29 are provided in the upper portion of the cylinder body 11, and a spring 30 is provided above and below the spring plate 29 for smoothing the movement of the rod 26 up and down. Yes. A pre-water storage space A is formed in the lower part of the cylinder body 11, and a lower valve 32 is provided at the lower end of the body 11 so as to open upward and have a lower through hole 31. The upper and lower valves 22 and 32 are formed in a spherical shape, but may be formed in a plate shape that can be easily operated with resin or the like. 33 is a lower stay, and 34 is an upper net.

Reference numeral 36 denotes an inner water ejection port, which is opened in a peripheral portion of the pressurized delivery space B corresponding to the space between the partition plate 28 of the cylinder body 11 and the piston 20, and an inner water ejection pipe 37 as a pipe communicating with the ejection port 36.

An upper float 41 is provided at the tip of the arm 40, and the main parts of the apparatus such as the cylinder main body 11, the lower pipe 13 and the synchronization interlocking mechanism 16 are vertically moved together with the lower float 42. The main body upper part 11 is set up in a cylindrical shape so that a constant height portion comes to the water surface.

Reference numeral 45 is a guide holding means for moving the pump cylinder 10 up and down in accordance with the tides while keeping the pump cylinder 10 in a vertical state at a fixed position in the inland sea 2 so that the upper part of the cylinder body 11 is always on the water surface.
This guide holding means 45 has a fixed pipe 47 with a flange 46, and this pipe 47 is provided with through holes 48 for introducing seawater in the seabed water area 4, and level adjusting tools are provided at three or more locations on the flange 46.
