Embodiment Construction

[0018] The present invention will be further described below in conjunction with the accompanying drawings.

[0019] Such as Figure 1~Figure 3 As shown, a trash rack system, at the same time, there are two pairs of trash rack installation pillars 1 installed on the trash rack, one is the upper trash rack 2, fixed on the top of the trash rack installation pillar 1, and one is the lower trash rack Bar 3 sinks into the bottom of the canal. The tension rod 6 makes the flexible trash rack 7 open, and makes it perpendicular to the grid sheet 4 of metal texture, and the flexible trash rack 7 of the lower trash rack 3 is attached to the bottom of the canal. When the dirt gathers more or has spread to the front end of the flexible trash rack 7, a same kind of trash rack is placed on the spare trash rack installation pillar 1, for example, when the bottom trash rack 3 needs to be cleaned, at first the trash rack is free Put down a lower trash rack 3 on the trash rack installation pil...

Abstract

The invention discloses a trash rack system. The trash rack system is characterized by comprising at least three groups of trash rack mounting supports (1), wherein the two groups of trash rack mounting supports (1) are provided with upper trash racks (2) and lower trash racks (3) respectively; the trash rack mounting supports (1) are provided with gate grooves for the upper trash racks (2) or the lower trash racks (3) to move up and down; the upper trash racks (2) and the lower trash racks (3) comprise rack plates (4) capable of moving in the gate grooves up and down; a plurality of lifting rings (5) are arranged at the tops of the rack plates (4); the two corners of the tops of the rack plates (4) are connected with the front end of a flexible trash net (7) through tension rods (6); the rear end of the flexible trash net (7) is movably connected with the bottom ends of the rack plates (4). The trash rack system disclosed by the invention is simple in structure; the trash racks can be lift out of a river channel; the trash rack system is convenient to clean and maintain and is relatively safe.

Description

technical field [0001] The invention relates to a trash rack system, in particular to a device for trapping trash step by step, and belongs to the technical field of trash blocking and cleaning in water diversion channels. Background technique [0002] The trash rack can prevent driftwood, branches, leaves, weeds, garbage, ice floes and other floating objects from entering the water inlet with the water flow, and at the same time prevent these dirt from blocking the water inlet and affecting the water inlet capacity. The primary trash control device is the trash rack at the intake. Floating debris in many rivers increases sharply during flood periods, and the trash grid at the water inlet is easy to block. If the pollution is not cleaned in time, the hydropower station or pumping station may be forced to reduce its output or even shut down, and there are often cases of crushing the trash rack at the water inlet. In order to reduce the pressure on the trash rack at the wate...
