Abstract
The invention relates to an anti-floating device of a catchment trough, which is characterize in that an end of a flapdoor with the turning plates having two sealed sides is connected with a floating box through a hinge; the floating box is conical; a top end of the conical floating box is provided with a balanced screw provided with a matching block; two sides of the conical floating box are sealed; one side of the conical floating box is in the same plane as the flapdoor with the turning plates. The anti-floating device has no external power and is the anti-floating device of the catchment trough to realize automatic starting and closing by gravity and buoyancy. The invention is safe and reliable in operation, applicable for anti-floating of the catchment trough of arc circular type or finger-shaped type for water treatment, and is capable of adjusting the required anti-floating force. When water enters an empty pond and the water level is higher than a bottom of the catchment trough, the anti-floating device is automatically opened, so water can flow into the catchment trough which can be prevented from floating; when the water level further rises to a set position, the anti-floating device is automatically closed; when the water pond is empty and the water level falls, the anti-floating device is opened automatically to discharge all the accumulated water in the trough.
Description
Technical field:
The present invention is applicable to that water treatment field has the structures of water leg, specifically is used for a kind of water collecting sink anti-floating equipment like circle or rectangle primary sedimentation pond and secondary sedimentation basins.
Background technology:
The water treatment field structures that have water leg commonly used, like circle or rectangle primary sedimentation pond and secondary sedimentation basins, the water in the pond gets in the water leg through overflow.When empty pond, pond intakes; Pond water could flow in the water leg after must reaching the water leg flood level; Water leg will bear huge buoyancy the process of flood level when water level rises at the bottom of the water leg gradually; If the thin weight of water leg wall thickness is not enough, and phenomenons such as water leg come-up, torsional deformation can take place with pond civil engineering supporting structure strength of joint when not enough; During emptying, the pool inner water position descends rapidly, but if the water in the water leg be can't descend the time simultaneously, and water leg will bear huge hydraulic pressure.Therefore be employed in the bottom land mode of perforate at interval usually, but can at the bottom of the pond, form spring one by one, a large amount of suspended substances are gone out from the hole with current, influence effluent quality.
Summary of the invention:
The invention provides a kind of anti-floating device that is used for water leg for addressing the above problem, the device that it can open, close according to change of level inside and outside the water leg automatically neither can cause water leg to bear huge hydraulic pressure, has also avoided the spring phenomenon that at the bottom of the pond, forms.
Technical scheme of the present invention is achieved in that a kind of water collecting sink anti-floating equipment; It mainly comprises buoyancy tank; It is characterized in that: an end of the turnover panel flap valve that two sides is all airtight is connected with buoyancy tank through hinge; Buoyancy tank is tapered, and the top of taper buoyancy tank is provided with a balance screw rod, and this balance screw rod is equipped with a balancing weight; The two sides of taper buoyancy tank is sealed shape, and the wherein one side of taper buoyancy tank is same plane with the turnover panel flap valve.
The present invention is owing to an end of the turnover panel flap valve that is provided with is connected with buoyancy tank; And buoyancy tank is equipped with a balancing weight; This anti-floating device is installed on circular arc type or refers to type water leg end, and the big more inflow-rate of water turbine of water leg inside and outside differential pressure is big more, when water level reaches flood level outside the water leg; The anti-floating device cuts out automatically, prevents short stream; Automatically open during pond emptying, get rid of water in the water leg.Every groove only need be installed and severally just can solve the anti-floating problem during enforcement, reduces the requirement of water leg structure anti-floating, reduces investment outlay.
Description of drawings:
Fig. 1 is a structural representation of the present invention
Fig. 2 is that the A of Fig. 1 is to synoptic diagram
Embodiment:
Below in conjunction with accompanying drawing and embodiment the present invention is done further description.
The present invention is a kind of anti-floating device that is used for water leg; This water collecting sink anti-floating equipment is different from prior art and is: an end of the turnover panel flap valve 2 that two sides is all airtight is connected with buoyancy tank 1 through hinge; Buoyancy tank 1 is tapered; The top of taper buoyancy tank is provided with a balance screw rod 3, and this balance screw rod is equipped with a balancing weight 4; The two sides of taper buoyancy tank is sealed shape, and the wherein one side of taper buoyancy tank is same plane with turnover panel flap valve 2.The present invention is connected with buoyancy tank by 1, one one end of a buoyancy tank during enforcement, and there are the turnover panel flap valve 2 of watertight rubber 7, balancing weight 4, two stop nuts 5 and balance screw rods 3 in both sides, and other materials all adopts the 316L stainless steel except that watertight rubber.The other end of turnover panel flap valve 2 is free shape in the specific implementation; Watertight rubber 7 all is equipped with in the both sides of turnover panel flap valve 2; The two sides of the taper buoyancy tank that directly is connected with turnover panel flap valve 2 and the two sides of turnover panel flap valve 2 all can be airtight, before umklapp process He after the umklapp process, all can close fully; One end of the described turnover panel flap valve 2 of present embodiment is connected with the bottom of buoyancy tank 1 through a hinge 8; Be provided with a balance screw rod 3 in the upper end of buoyancy tank 1, the upper and lower end that is contained in the balancing weight 4 on the balance screw rod 3 is equipped with stop nut 5, the adjustable force moment device of being made up of stop nut and balancing weight; Two stop nuts and turnover plate type on-off structure; Lean on hydraulic pressure to realize sealing, buoyancy tank and the control of adjustable force moment device open and close water level, and change buoyancy moment by the position of regulating balancing weight.
The buoyancy tank that is connected with the turnover panel flap valve during use can be done 0 ~ 120 degree rotation on the balance screw rod under aquagenic buoyancy and balancing weight effect; Water level rises at the bottom of the water leg the process on water leg top and realizes that automatically the turnover panel flap valve from reaching the process of pass, reaches the purpose of anti-floating outside water leg; Otherwise water level is realized the turnover panel flap valve from closing to the process of opening automatically from the process at the bottom of water leg top drops to water leg outside water leg, reaches and reduces the purpose that trough inner water is pressed.
Concrete dynamic declaration is following:
When 1. empty pond, pond intake, when water level rose near the water leg bottom gradually, the buoyancy tank of anti-floating device was risen with water level by buoyancy effect, and the turnover plate type flap valve is opened simultaneously, and water gets into the water leg from the flap valve of opening, the buoyancy that receives at the bottom of the offset slot;
2. water level continues to rise, and buoyancy tank is raised under buoyancy synchronously, and the turnover plate type flap valve is closed under buoyancy that receives buoyancy tank and the effect of hydrostatic difference, and water leg gets into normal operation;
3. during emptying, the pool inner water position descends rapidly, and the turnover plate type flap valve is opened with the decline of buoyancy tank, and water is discharged rapidly in the water leg.
