Abstract

The utility model discloses a floating type triangular drain grating, which relates to a drain grating, which consists of a framework and a grating body (8), wherein the framework is mainly circulated by a vertical frame (1) and transversal frames (2), and the grating body (8) are formed by grating bars (3) connected between the upper transversal frame and the lower transversal frame. The floating type triangular drain grating also comprises floating bodies (5), press blocks (6) and anchor blocks (7), the transversal frames (2) are in a reverse V shape, in addition, both ends are connected with a support rod (4) for circulating into a triangle, the whole grating body (8) forms a triangular prism, the drain grating is formed by a plurality of grating bodies (8) through being movably connected in series, a pair of floating bodies (5) are arranged on the upper part of each grating body (8), the lower part of each grating body (8) is connected with one press block (6) through a long chain, and every five grating bodies (8) are connected with one anchor block (7) through long chains. Cases of the floating bodies (5) are made of high molecular polyethylene, and rigid polyurethane is filled in the cases. The utility model has the advantages of high rigidity, difficult deformation and capability of lifting along the water level, and can adapt to the lifting conditions of different water levels.

Description

A kind of floatation type triangle trashrack

Technical field

The utility model relates to a kind of trashrack, relates in particular to a kind of floatation type triangle trashrack.

Background technology

Trashrack is mainly used in the dirt that interception power station or pumping station etc. send the drainage works water inlet at present, as branch, household garbage, pasture and water etc., prevents that floating thing or creep thing from entering pumping plant, guarantees the safe operation of pumping plant.But at present the trashrack that generally uses all is a plane, i.e. yi word pattern trashrack, and its rigidity is relatively poor.Before a large amount of floating things was deposited in trashrack, the very big water-head of the inside and outside formation of grid promptly formed very big pressure differential, and the result makes the trashrack distortion, lost efficacy, and enters the water pump intake chamber together with floating thing, causes the water pump cisco unity malfunction.And present common trashrack all is fixed, can not be with the water level automatic lifting, and when water level exceeded trashrack, trashrack promptly lost the effect of interception floating thing.

The utility model content

At the problem that above-mentioned prior art exists, the utility model provides a kind of floatation type triangle trashrack, rigidity by force, not yielding, and can fluctuation in stage, adapt to the lifting situation of different water levels.

The technical solution of the utility model is: a kind of floatation type triangle trashrack, comprise mainly the framework that surrounds by vertical edge frame, horizontal edge frame and be connected the grid body that the grizzly bar between the upper and lower horizontal edge frame is formed, also comprise buoyancy aid, briquetting and anchor block, described horizontal edge frame is " ∧ " font, and two ends are connected with support bar and surround triangle, and whole grid body forms a triangular prism; Described trashrack is flexibly connected by a plurality of grid bodies and is composed in series, and a pair of buoyancy aid is installed on each grid body top, and the bottom connects a briquetting by long-chain, and per 5 grid bodies connect an anchor block by long-chain.

As preferably, described buoyancy aid shell is made by high-molecular polythene, in fill hard polyaminoester.

The beneficial effects of the utility model are: because upstream face adopts triangle, reduced resistance to water-flow, and triangle has better stability and intensity; Whole trashrack is flexibly connected by a plurality of grid bodies and is composed in series, and can connect a plurality of grid bodies according to the different dirty width that blocks, and compliance is stronger; Buoyancy aid by grid body top makes trashrack floating, makes trashrack keep vertical state by briquetting, following water-level lifting and lifting adapts to different SEA LEVEL VARIATION.

The specific embodiment

As a kind of embodiment of the present utility model, as shown in Figure 1 to Figure 3, a kind of floatation type triangle trashrack, comprise mainly the framework that surrounds by vertical edge frame 1, horizontal edge frame 2 and be connected the grid body 8 that the grizzly bar 3 between the upper and lower horizontal edge frame is formed, frame can be made by channel-section steel or angle steel, grizzly bar 3 is a round steel, spacing between the adjacent grill 3 is about 8cm, and (6～10cm) also comprise buoyancy aid 5, briquetting 6 and anchor block 7, described horizontal edge frame 2 is " ∧ " font, and two ends are connected with support bar 4 and surround triangle, and whole grid body 8 forms a triangular prism; " ∧ " font horizontal edge frame 2 and grizzly bar 3 are formed the upstream face of trashrack, described trashrack is flexibly connected by a plurality of grid bodies 8 and is composed in series, can block the grid body 8 that dirty width connects suitable number and be composed in series trashrack according to different, on the vertical edge frame 1 of each grid body 8, connecting ring is set, adjacent grid body 8 connects by the hinge that connects between the connecting ring, a pair of buoyancy aid 5 is installed on each grid body 8 top, buoyancy aid 5 makes grid body 8 keep floating state, following water-level lifting and rising and falling, the bottom connects a briquetting 6 by long-chain, briquetting 6 makes grid body 8 keep vertical state, and per 5 grid bodies 8 connect an anchor block 7. described buoyancy aid 5 shells by long-chain to be made by high-molecular polythene, anticorrosive, non-caked aquatic organism, in fill hard polyaminoester, buoyancy can reach 1300 kilograms, buoyancy is big.

Claims

1. floatation type triangle trashrack, comprise mainly the framework that surrounds by vertical edge frame (1), horizontal edge frame (2) and be connected the grid body (8) that the grizzly bar (3) between the upper and lower horizontal edge frame is formed, it is characterized in that: also comprise buoyancy aid (5), briquetting (6) and anchor block (7), described horizontal edge frame (2) is " ∧ " font, and two ends are connected with support bar (4) and surround triangle, and whole grid body (8) forms a triangular prism; Described trashrack is flexibly connected by a plurality of grid bodies (8) and is composed in series, and a pair of buoyancy aid (5) is installed on each grid body (8) top, and the bottom connects a briquetting (6) by long-chain, and per 5 grid bodies (8) connect an anchor block (7) by long-chain.
