Problems solved by technology
The gate controls water storage or discharge by turning. The gate shaft at the bottom of the gate will rotate synchronously. Water leakage will occur during the rotation of the gate shaft. It relies on the weight of the gate itself to compress the rubber to prevent leakage, but the effect of bottom water sealing is not ideal, which directly affects the working effect of the gate and has certain safety hazards, such as causing the gate to vibrate

Embodiment Construction
[0014] The present invention will be described in detail below in conjunction with the implementations shown in the drawings, but it should be noted that these implementations are not limitations of the present invention, and those of ordinary skill in the art based on the functions, methods, or structural changes made by these implementations Equivalent transformations or substitutions all fall within the protection scope of the present invention.
[0015] Such as figure 1 The movable steel gate shown includes a gate 1, a seat body 14, a hydraulic mechanism 13, a connecting rod 12, a gate rotating shaft 11 and a water stop 2 at the bottom of the movable steel gate rotating shaft. The gate 1 can rotate back and forth along the X direction under the joint action of the hydraulic mechanism 13 and the connecting rod 12, so as to realize water storage or discharge.
[0016] Such as figure 2 The bottom water stop 2 of the movable steel gate shaft shown includes a water stop supp...

The invention provides a movable steel gate rotary shaft bottom waterstop, which comprises a waterstop supporting plate, a waterstop pressing plate located above the waterstop supporting plate, a rubber pad located between the waterstop supporting plate and the waterstop pressing plate, a waterstop rubber limited in the waterstop pressing plate, and a fixing piece for connecting the waterstop supporting plate and the waterstop pressing plate. The waterstop rubber comprises a first waterstop bar, a second waterstop bar and a connecting part for connecting the first waterstop bar and the second waterstop bar; and the first waterstop bar, the second waterstop bar and the connecting part jointly form a rotary shaft clamping and holding slot. Through enabling the first waterstop bar, the second waterstop bar and the connecting part of the waterstop rubber jointly form the rotary shaft clamping and holding slot, a gate rotary shaft is arranged in the rotary shaft clamping and holding slot, so that the gate rotary shaft squeezes the waterstop rubber and still fit to the first waterstop bar and the second waterstop bar during a rotation process, the occurrence of the phenomenon that the bottom part of the gate is leaky during the rotation process is prevented, and an effect on stopping water at the gate bottom is improved.
Description
technical field [0001] The invention relates to the technical field of a bottom water stop mechanism, in particular to a bottom water stop of a rotating shaft of a movable steel gate. Background technique [0002] The movable steel gate is a low-head hydraulic structure built on the banks of rivers, channels, reservoirs, and lakes, and has the functions of water retaining and water release. Closing the gates can block floods, block tides, and raise water levels to meet the needs of upstream water intake or navigation; opening gates can discharge floods, drain water, flush sand, draw water, or adjust flow according to downstream water needs. The gate controls water storage or discharge by turning. The gate shaft at the bottom of the gate will rotate synchronously. Water leakage will occur during the rotation of the gate shaft. It relies on the weight of the gate itself to compress the rubber to prevent leakage, but the effect of bottom water sealing is not ideal, which direc...
