Description
Technical field
Easy-to-dismount exempt from the full-automatic sluice of the energy the invention discloses a kind of.
Background technology
At present, middle river channel both domestic and external and the existing hydraulic elevation type of sluice in lake, also there is electric or hand formula, this
Mostly there is the defects of manually speed is slow or electronic energy loss is big in a little sluice, and after sluice installation, it is difficult to tear open
Unload, inconvenience maintenance.Up to the present, it is there is not yet a kind of easy for assembly, disassembly and maintenance, it is not required to again without any energy manually-operated
One kind exempts from the full-automatic sluice of the energy.
On the dismounting of sluice, specifically, the flashboard service life of standard machinery or manpower driving is generally 30~50 years, but
The flashboard of full-automatic sluice lost of life in the case of the impact of bulk debris because of continually automatic rotary oscillation and in flowing water,
Such as the flashboard service life of full-automatic sluice is only the several years, and shaft is generally all locked in gate pier by current sluice using cementing
In, this method is unfavorable for replacing flashboard and replaces the sealing structure being fixed on flashboard, thus this area needs a kind of assembly and disassembly dimension
Repair convenient full-automatic sluice.
The content of the invention
The object of the present invention is to provide a kind of easy for assembly, disassembly and maintenance, without any energy and it is not required to manually-operated a kind of complete
Automatic water gate.
The present invention provides a kind of easy-to-dismount full-automatic sluice, including be arranged on along water (flow) direction the left and right sides of current
Two gate piers (1), be fixed on gate pier (1) and be used for sealing plate (2), the lock being arranged between two gate piers for sealing current
The sealing for being used to prevent current from leaking during water storage at flashboard left and right sides and at base is arranged on when plate (3), sluice water storage
Structure (4), the rotating shaft base (5) being arranged in gate pier (1) the latter half, the cylinder being arranged in the cylindrical hole of rotating shaft base
Shape copper sheathing (6), left and right ends are arranged on the shaft (11) in copper sheathing, along water (flow) direction from upstream toward downstream on the gate pier (1)
Direction offers mounting groove (1a), at least installed therein from the direction of upstream toward downstream for the rotating shaft base (5), described
Shaft (11) includes the interlude (11a) that is fixedly connected with flashboard and positioned at its left and right ends and is arranged in the copper sheathing (6)
Cylindrical section (11b), the full-automatic sluice, which further includes, to be arranged in mounting groove and positioned at the jacking block of rotating shaft base (5) upstream
