Abstract
The utility model relates to an anti-floating device for a water collecting groove. The side wall of the water collecting groove is provided with a hole, the hole is slantwise provided with a flap valve, the water collecting groove is externally provided with a hanging bracket, a pulley wheel and a steel cable matched with the pulley wheel are arranged on the hanging bracket, one end of the steel cable is connected with the lower end of the flap valve, the other end of the steel cable is connected with a float bowl, and a base is arranged under the float bowl. According to the anti-floating device, the side wall of the water collecting groove of a settling pond is provided with the hole, is simultaneously provided with the flap valve, and is connected with the float bowl by the means that the steel cable surrounds the pulley wheel, and the opening and closing of the flap valve can be controlled due to the height of the water level of the settling pond, so that a buoyancy force of the water in the pond to the water collecting groove can be greatly reduced, an acting force to the water collecting groove can be reduced, the structural requirement of the device can be reduced, the building cost of civil engineering can be reduced, and the quality of discharged water can be further observably improved compared with that of the discharged water treated by an original anti-floating method.
Description
Technical field
The utility model relates to water treatment water leg, particularly float resistant apparatus for water accumulating tank.
Background technology
At present, the water treatment field structures with water leg commonly used, such as circle or rectangle primary sedimentation pond and secondary sedimentation tank, water leg is installed on the sedimentation basin crossbeam, and the water in the pond enters in the water leg by overflow.
Pond water could flow in the water leg after must reaching the water leg flood level, during the water inlet of empty pond, pond, at the bottom of water level reaches water leg and rise to gradually that water leg bears larger buoyancy in the process of flood level; During pond water emptying, the pool inner water position descends rapidly, but the water in the water leg can not descend simultaneously, and water leg bears larger hydraulic pressure.
Higher to the water leg requirement of strength when manufacturing and designing like this, and higher to sedimentation basin supporting construction requirement of strength, connect and want reliable, the phenomenons such as water leg come-up, torsional deformation can occur often.Be generally and be convenient to Inlet and outlet water, interval perforate at the bottom of water leg, but at the bottom of the pond, easily form one by one spring, a large amount of suspensions are gone out from the hole with current, affect effluent quality.
The utility model content
The purpose of this utility model is for above-mentioned the problems of the prior art, and a kind of float resistant apparatus for water accumulating tank is provided, and can automatically regulate the water leg water level according to SEA LEVEL VARIATION inside and outside the water leg.
To achieve these goals, the technical solution of the utility model is as follows: a kind of float resistant apparatus for water accumulating tank, described water leg side-wall hole, tapping is tiltedly installed with a flap valve, described water leg arranges a suspension bracket outward, the cable wire that suspension bracket is provided with a pulley and matches with this pulley, and an end of cable wire is connected with the lower end of flap valve, the cable wire other end is connected with floating drum, and the below of floating drum is provided with a pedestal.Wherein the angle of flap valve and horizontal direction is 5 ° ~ 30 °.
The utility model passes through at sedimentation basin water leg side-wall hole, flap valve is set simultaneously, walk around pulley by cable wire and connect floating drum, height control flap valve by the sedimentation basin water level opens and closes, and can greatly reduce Chi Shui to water leg buoyancy, reduces the active force to water leg, reduced its structural requirement, reduce the civil engineering construction cost, compare with former anti-float method, also significantly improved effluent quality.
Description of drawings
Fig. 1 is the utility model installation site schematic diagram.
Fig. 2 is the utility model float resistant apparatus for water accumulating tank structural representation.
The specific embodiment
Fig. 1 is typical circular settling tank schematic diagram, and water leg 1 is installed on the crossbeam 3 that cantilevers out from pool wall, and float resistant apparatus for water accumulating tank 2 of the present utility model also is installed on the crossbeam.
This device construction as shown in Figure 2, a kind of float resistant apparatus for water accumulating tank, described water leg 1 side-wall hole 4, perforate 4 places are provided with flap valve basis 5, and a flap valve 6 is installed on the flap valve basis 5, and described water leg arranges a suspension bracket 7 outward, the cable wire 10 that suspension bracket is provided with a pulley 8 and matches with pulley 8, one end of cable wire 10 is connected with the lower end of flap valve 6, and cable wire 10 other ends are connected with floating drum 9, and the below of floating drum 9 is provided with a pedestal 11.Between primary sedimentation pond or secondary sedimentation tank and water leg 1 crossbeam 3 is arranged, suspension bracket 7 is fixed on the described crossbeam 3.
Because flap valve 6 tilts to install, when the cable wire pine, the vertical force component of pulling force is during less than the gravity of flap valve, and flap valve is closed.When cable wire was tight, the vertical force component of pulling force was during greater than the gravity of flap valve, and flap valve is opened.Cable wire provides pulling force by floating drum, and floating drum is to gravity and the buoyancy acting in conjunction by floating drum of the pulling force of cable wire.So just can be controlled by the variation of water level the switching of flap valve.According to preferred embodiment of the present utility model, the angle of inclination of flap valve and horizontal direction is 5 ° ~ 30 °.The external diameter of floating drum is 80 ~ 100mm, and internal diameter is 75 ~ 95mm, highly is 150 ~ 200mm.
The structure of related water leg, flap valve, flap valve basis, suspension bracket and floating drum is prior art in the utility model, does not repeat them here.
