Embodiment Construction

[0033] A kind of cable suspension trash row, see figure 1 , figure 2 , image 3 , Figure 4 , mainly consists of a number of buoyancy tanks 1, anchor chains 2, trash nets 3, buoyancy tank hoops 4, "U"-shaped rings 5, pendants 6, "U"-shaped bolts 7, end positioning devices 8, shackle elastic devices 9 composition.

[0034] The two ends of the trash row can be designed as fixed or movable positioning devices 8 according to the amplitude of the water level. The two ends of the anchor chain 2 as the main suspension cable are connected to the end positioning devices through swivel shackles. Hanging rope. The anchor chain is connected to the bottom of the buoyancy tank 1 through the pontoon hoop 4 and the "U"-shaped lifting ring 5; Online upstream, the two are arranged in parallel. A pendant 6 is hung under the trash-stop, so that the trash-block is in a suspended state underwater.

[0035] Under the joint action of power generation diversion water flowing from the reservoir...

Abstract

The invention discloses an anchor chain span wire trash holding row. The anchor chain span wire trash holding row aims to solve the problem that a wharf boat trash holding row, a steel wire rope trash holding row and a mooring rope trash holding row are too high in manufacturing cost or short in service life or low in safety. The anchor chain span wire trash holding row comprises an anchor chain as a main span wire, a plurality of floating boxes connected to the main span wire, a trash holding net hung on the lower portions of the floating boxes and plummets arranged on the lower portion of the trash holding net. Floating box lock rings are arranged on the floating boxes in a sleeved mode, and the floating box lock rings are connected to the anchor chain through U-shaped hanging rings. The anchor chain is arranged on the upstream side of the trash holding net. The anchor chain span wire trash holding row is good in trash holding effect, long in service life and high in safety performance.

Description

technical field [0001] The invention relates to a trash rack for intercepting dirt in front of a water inlet (hydropower station or water diversion project), in particular to a trash rack composed of anchor chains, floating tanks and trash nets. Background technique [0002] In my country, most of the hydropower stations, especially the riverbed run-of-river hydropower stations, have accumulated a large amount of floating objects in front of the trash racks. The existence of these floating objects not only increases the head loss of the water inlet of the power station, but also seriously interferes with the normal operation of the generating units. , affecting the power generation efficiency, especially during the flood period, the unit cannot operate at full load due to the blockage of floating debris, and the economic loss is huge. In order to solve this problem, more and more hydropower stations have installed floating trash racks in front of the water inlet as the first ...
