The working principle is as follows: when the device is used, firstly, the buoy device is taken to a position to be tested, when the buoy body 8 is required to be installed at the bottom of the floating plate 1, the buoy body 8 is taken to the bottom end of the floating plate 1, the outer interface 703 is butted to the bottom end of the inner interface 702, the auxiliary rotating sheet 706 is rotated to enable the auxiliary rotating sheet 706 to drive the outer interface 703 to rotate, the outer interface 703 is gradually sleeved outside the inner interface 702 in the rotating process, the auxiliary rotating sheet 706 is continuously rotated to enable the outer interface 703 to rotate and move upwards outside the inner interface 702, when the outer interface 703 rotates to the bottom end of the fixing hole 701 and is in contact with the fixing hole 701, the installation and fixation of the buoy body 8 are completed, meanwhile, the sealing ring 704 can seal the interface, and water is not easy to permeate into the buoy body 8 through the sealing ring 704;

secondly, when the area of the floating plate 1 needs to be increased, the floating plate 1 and the other floating plate 1 are taken to the same horizontal plane, the fixture block 502 is abutted to one side of the fixture groove 506 of the other floating plate 1, the fixture block 502 is inserted into the fixture groove 506, the limiting column 507 is inserted into the limiting hole 503 at the moment, the limiting hole 503 can enable the limiting column 507 to be fixed in the limiting hole 503, the fixture block 502 is continuously pushed into the fixture groove 506, when the fixture block 502 is pushed into the bottommost part of the fixture groove 506, the reserved block 508 can be limited in the reserved groove 504, the fixture block 502 can be fixed in the fixture groove 506, the limiting column 507 is fixed in the limiting hole 503, and the reserved block 508 is limited in the reserved groove 504, so that the fixture block 502 is not easy to fall off from the interior of the fixture groove 506;

finally, when the floating plate 1 and the buoy body 8 need to be fixed, an operator turns over the fixing ring 1205 by hand to make the fixing ring 1205 perpendicular to the bottom end of the buoy body 8, at this time, the fixing ring 1205 can rotate the movable post 1204 inside the movable groove 1208 through the movable block 1203, at the same time, the movable block 1203 can also turn over inside the notch 1202, the fixing ring 1205 can be perpendicular to the bottom end behind the buoy body 8, then, the pressing ring 1207 is pressed to make the pressing spring move to one side inside the hook 1206, the bottom end of the pressing ring 1207 can rotate at the bottom end of the hook 1206, the hook 1206 can be opened, the hook 1206 is hung inside the fixing ring 1205, the pressing ring 1207 is released, the bottom end of the pressing ring 1207 can rotate at the bottom end of the hook 1206 through the telescopic action of the spring, the top end of the pressing ring 1207 can be pressed inside the hook 1206, the pressing ring 1207 can make the hook 1206 be closed, the bottom end of the pressing ring 1207 is fixed to the fixing rope 11, the fixing rope 11 is fixed to the water bank, the floating plate 1 and the buoy body 8 are fixed, and finally the use work of the buoy device for the liquid level sensor is finished.

It will be evident to those skilled in the art that the invention is not limited to the details of the foregoing illustrative embodiments, and that the present invention may be embodied in other specific forms without departing from the spirit or essential attributes thereof. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. Any reference sign in a claim should not be construed as limiting the claim concerned.
