Problems solved by technology
[0005] The technical problem to be solved by the present invention is that in the existing water supply and drainage engineering equipment technology, there are technical defects that the vertically controlled opening or closing of the ram consumes a lot of power, and the pre-compressed sealing strip is easy to wear, resulting in lax sealing and easy water leakage.

Embodiment 2
[0115] Corresponding to Embodiment 1 of this specification, Embodiment 2 of this specification provides a drainage device, including the rotary weir gate with a sealing structure provided in Embodiment 1 above. It can be understood that the drainage device can be any one of the pipe network systems. A drainage device, such as a drainage device that includes a septic tank, a buffer tank, an intercepting well, etc., and when the drainage device includes the rotary weir door with a sealing structure provided in the first embodiment, for such as a septic tank, When buffer tanks, interception wells or other pool structures need to be drained and sealed, the rotary weir gate in the drainage device can be used to replace the conventional vertical gate control method, which effectively solves the problem of vertical gates in the prior art. The power consumption of the gate that controls the opening or closing is large, and the pre-compression sealing strip is easy to wear, resulting in...

The invention discloses a rotary weir gate with a sealing structure. The rotary weir gate comprises a weir gate bottom plate, the weir gate side plate is fixed at the side part of the weir gate bottom plate; the weir gate shaft is arranged between the weir gate side plates; the checkgate plate is fixed between the checkgate side plates through a checkgate shaft and can rotate relative to the checkgate side plates or the checkgate bottom plate; the sealing structures are arranged on the peripheral portion of the checkgate door plate, are filled at the joint portion of the checkgate door plate and the checkgate side plate and are filled at the joint portion of the checkgate door plate and the checkgate bottom plate, and the sealing structures can expand or contract, so that the contact surfaces of the sealing structures and the checkgate side plate are tightly attached or loosely attached; and / or the sealing structure is tightly attached to or loosely attached to the contact surface of the weir gate bottom plate. The check gate sealing structure effectively solves the technical problems that in the check gate rotating process, due to friction between the sealing structure and the check gate side plate or the check gate bottom plate, sealing of the sealing structure is not tight, and water leakage is prone to occurring, and has the technical advantages of being low in cost, good in sealing effect and wide in applicability.
Description
technical field [0001] The invention belongs to the technical field of drainage, in particular to a rotary weir gate with a sealing structure. Background technique [0002] The gate is a control facility for closing and opening the discharge (discharging) channel. Gates are an important part of hydraulic structures, which can be used to intercept water flow, control water level, regulate flow, discharge sediment and floating objects, etc. [0003] At present, for the existing water supply and drainage engineering equipment technology, the traditional sealed gate uses wedges installed on both sides of the door leaf. The components of the door slot are formed by secondary concrete pouring on site. The bottom sill and lintel of the gate are also fixed on the concrete structure by secondary pouring. When the sealed gate is running, the drive device drives the gate to move up and down in the vertical direction. In this way, due to the gravity of the gate itself, the driving fo...
