firstly, when the gate descends, the buoyancy of water can generate a certain 'reaction' on the gate more or less no matter the weight of the gate, and furthermore, the friction between the gate and the opening and closing track is increased due to the action of water pressure (i.e. when the gate descends, the friction of water on the gate is opposite, namely upwards, so that the friction has a certain influence on the descending of the gate), for example: due to the existence of friction force (and buoyancy force), when the gate descends (namely, when the water discharge channel is closed), the gate is extremely difficult, and the gate cannot descend to the bottommost layer, so that the matching of the gate and the water gate hole has certain defects;
secondly, when the gate is lifted, the 'door lifting' device needs to bear the gravity of the gate and overcome the friction force of water on the gate in the lifting process of the gate due to the resistance of water on the gate (namely, when the gate is lifted in water, the friction force of water on the gate is downward), so that the load of the 'door lifting' device is rapidly lifted, and the use stability of the gate is influenced;
