Accompanying drawing explanation
Fig. 1 is the structural representation that dirty device is blocked in the utility model power station;
Fig. 2 is the structural representation of the utility model garbage barrier net.
Detailed description of the invention
Below in conjunction with Figure of description, the utility model is further described.
As shown in Fig. 1 to 2, dirty device is blocked in the present embodiment power station, comprises the first symmetrical column 1 and the second column 2, and described first column 1 and the second column 2 are hydraulically extensible column; At the first described column 1 and the second column 2, be connected to the trashrack between described first column and the second column, described trashrack comprises two pieces of garbage barrier nets, two pieces of garbage barrier nets are installed in housing, hinged by hinge 9 between two housings, described two housings are arranged above and below, and the side that two described columns are relative has guide rail groove, the two ends of fence body are provided with guide roller 3, and fence body is slidably arranged in guide rail groove by guide roller.
Be provided with rotating shaft 5 in the below of trashrack 4, described rotating shaft 5 is connected with trashrack net 6, the second column 2 offers installing hole, described rotating shaft 5 is passed installing hole and is connected with rocking handle 7, and be provided with bearing 8 in described installing hole, rotating shaft 5 is through bearing 8.
In the present embodiment, bearing 8 is chosen as taper roll bearing, and taper roll bearing belongs to divergence type bearing, and the inside and outside circle of bearing all has tapered raceway.This class bearing is divided into single-row, that biserial and four-row tapered roller bearing etc. are different structural shape by the columns of filled roller.Single-row tapered roller bearing can bear radial load and single direction axial load.When bearing bears radial load, an axial thrust load will be produced, so when the bearing needing another can bear axial force is in the other direction balanced.
Be provided with horizontal grizzly bar 40 and longitudinal grizzly bar 41 in described trashrack 4, whole trashrack 4 is divided into the fence grid of several regular array by described horizontal grizzly bar 40 and longitudinal grizzly bar 41, and described horizontal grizzly bar 40 and longitudinal grizzly bar 41 are hollow.
Some floating drums 22 are connected with in described garbage barrier net 6 upper edge, in described garbage barrier net upper edge, high-strength high-modulus polyethylene fiber rope 24 is set, each floating drum 22 whole body is respectively equipped with groove 25, in each floating drum 22 periphery along described groove 25 lock ring high-strength low-ductility rope 26 respectively, each floating drum 22 is connected with high-strength high-modulus polyethylene fiber rope 24 respectively by high-strength low-ductility rope 26, in the lower edge of garbage barrier net 6, immediately below each floating drum 22 respectively by rope 27 colligation outstanding pendant chain 23, the length of outstanding pendant chain 23 is consistent with floating drum 22 length.Garbage barrier net 6 is formed by three bursts of nylon rope braidings of diameter >=40mm, and the mesh length of side of garbage barrier net 1 is >=50mm.
