Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings. To facilitate a more clear understanding by those skilled in the art.

As shown in fig. 1, the utility model comprises a plurality of suspension units 2 which are evenly distributed in a sewage pool 1;

as shown in fig. 2, 3 and 4, the hanging unit comprises a left frame 2-1 and a right frame 2-2, a pair of upper cross rods 2-3 are connected between the upper parts of the left and right frames, the upper cross rods are uniformly connected with a plurality of upper longitudinal rods 2-5 along the length direction, a pair of lower cross rods 2-4 are connected between the lower parts of the left and right frames, the lower cross rods are uniformly connected with lower longitudinal rods 2-6 which are in one-to-one correspondence with the upper longitudinal rods along the length direction, a plurality of hanging ropes 2-7 are uniformly connected between each upper longitudinal rod and the corresponding lower longitudinal rod, and biological fillers are hung on the hanging ropes from top to bottom; the suspension unit is also connected with a hoisting assembly.

As the preferred embodiment of the utility model, the lifting component comprises a bearing rod 2-8, a lifting rod 2-9, a first lifting part 2-10 and a second lifting part 2-11, wherein the bearing rod is connected between the upper parts of the left frame and the right frame, the middle part of the bearing rod is connected with the lifting rod, the upper end of the lifting rod is connected with a pin shaft 2-12, the two ends of the first lifting part are respectively connected with a circular ring, the circular ring rotates to connect the end part of the pin shaft, the two ends of the second lifting part are respectively connected with the circular ring, the circular ring rotates to connect the end part of the pin shaft, the end part of the pin shaft is further sleeved with a torsion spring 2-13, one end of the torsion spring compresses the end part of the first lifting part, the other end of the torsion spring compresses the end part of the second lifting part, and the upper end of the lifting rod is further connected with a first supporting rod.

Further, the first hanging piece and the second hanging piece are higher than the water level of the sewage pool.

Preferably, the left frame, the right frame, the upper cross bar, the lower cross bar, the upper longitudinal bar, the lower longitudinal bar, the bearing bar and the lifting bar are all made of anticorrosive materials.

In the process of lifting for placing the suspension unit, due to the action of the torsion spring, the first support rod and the second support rod, the first suspension piece and the second suspension piece of the suspension unit are in a lying state in an initial state (as shown in fig. 4), the hook of the crane can very easily hook the first suspension piece (or the second suspension piece), under the action of a vertical upward lifting force, the hooked first suspension piece rotates and erects, the crane lifts the suspension unit to a preset position of a sewage pool, at the moment, the suspension rope of the crane is loosened, the vertical upward lifting force disappears, and under the action of the torsion spring, the first suspension piece rotates and resets to form a lying state, so that the hook of the crane can very easily separate from the lower part of the first suspension piece. When the suspension unit needs to be repaired or the biological filler needs to be replaced, the suspension unit can be lifted out of the wastewater tank by using a crane, and the process is the same as that described above and is not repeated.
