Gate sealing clearance adjustment mechanism

Abstract

The invention relates to a gate sealing clearance adjustment mechanism. The gate sealing clearance adjustment mechanism comprises a door frame and a door body, wherein guiding grooves are formed in inner sides of two sides of the door frame, eccentric shafts are respectively and transversely arranged on the left side and the right side of the door body, idler wheels are installed at front ends ofthe eccentric shafts, the idler wheels are located in the guiding grooves, the idler wheels make contact with the rear side faces of the guiding grooves, two pieces of water sealing rubber are respectively arranged on two sides of the front end face of the door body, bearing plates are respectively arranged in the left side and the right side of the door body, through holes are formed in the bearing plates, locking plates sleeve the tail ends of the eccentric shafts, a plurality of adjustment holes I are formed in each locking plate, the plurality of the adjustment holes I are uniformly distributed with the center of a multilateral hole as the axial center, adjustment holes II matched with the adjustment holes I are formed in the bearing plates, and the adjustment holes I are connected with the adjustment holes II through bolts. The gate sealing clearance adjustment mechanism is simple in structure and convenient to manufacture, and in the use process of the gate sealing clearance adjustment mechanism, the idler wheels are driven to rotate by rotating the eccentric shafts, the idler wheels roll in the guiding grooves so as to eliminate a clearance between each piece of the water sealing rubber and the inner side of the corresponding guiding groove, and the eccentric shafts are locked through the locking plates, and therefore water sealing effect of a gate is achieved.

Description

technical field [0001] The invention relates to a gate, in particular to a gate water-stop gap adjustment mechanism. Background technique [0002] The gate is used to close and open the control facility of the discharge (discharging) channel, an important part of the hydraulic structure, and can be used to intercept the water flow, control the water level, adjust the flow, discharge sediment and floating objects, etc. Existing gates include a door frame, door body, rollers and water-stop rubber. After the gate has been used for a period of time, gaps between the water-stop rubber and the door frame are likely to occur, resulting in water leakage and affecting the water-stop effect of the gate. In order to improve the water-stop effect of the gate , It is necessary to constantly replace the water-stop rubber, which increases the cost. Contents of the invention [0003] In view of the above-mentioned defects, the object of the present invention is to provide a gate water-st...
