Description

Automatic gate opening and closing device using link mechanism {.}

The present invention is a technology that the gate is automatically opened and closed to secure the water level of the desired fresh water side using the power. The water level sensor attached around the water gate detects the desired freshwater level and moves the link with hydraulic force to open the water gate. In the past, the floodgates were mostly upright and operated by manual and semi-automatic methods, so there was no way to cope with surprise storms or floods.

The present invention can be easily installed with a small budget, and it can prevent water turbulence by automatically opening the floodgate in case of surprise rainfall or flood. In addition, it is easy to secure water because it is possible to obtain the water level on the freshwater side which is usually desired, and it is possible to obtain high-quality water by improving the water quality due to the discharge of the lower part.

The present invention is intended to overcome this in view of the problems of the prior art. The prior art has suffered a great deal of property damage due to manual wastes and semi-automatic operations, resulting in wasted and watery human resources. The present invention aims to protect valuable water resources by automatically opening and closing the water gate with information obtained by the flow sensor installed on the freshwater side.

The main components to achieve the object of the present invention is a door frame, a water gate, a hydraulic piston bar, a water level detector, and the like, and a bracket and a hinge are mounted on the body and the water gate to fix and rotate it. The door frame is concretely placed by attaching it to both sides of the body using H beam, and the inclination angle of the water gate is equal to the angle of inclination of the right triangle on both sides of the door frame, and rubber is used as the packing material between the water door and the door frame.

The water gate uses stainless steel plate with a certain thickness (3M / M) or more to withstand the water pressure and reinforces it with a supporting member inside. Since the water gate must rotate to open and close with water pressure, it is connected to the hinge that is reinforced on the door frame support, and the link for opening and closing is connected to the lower left and right sides of the water gate. The hydraulic system is firmly fixed by brackets next to the hydrodynamic pivot and the cylinder is connected to the center of the three measures links. Two hydraulic piping lines are connected to the hydraulic cylinder for shrinking and expanding the cylinder with the hydraulic pressure generated from the hydraulic pump.

The link consists of two measures, consisting of two rotating shafts, the middle rotating shaft of which is connected to the hydraulic piston and the other two rotating shafts to the upper part of the body and the sluice side.

The water level detector allows the administrator to arbitrarily set the highest and lowest water level to ensure high quality water.The water level sensor is out of the set water level and immediately generates hydraulic pressure from the hydraulic pump.The water level can be automatically opened and closed to obtain the set water level. have.

The operation of the present invention is to open and close the gate automatically by the various components of the above. If the administrator sets the level of the level sensor arbitrarily, when the water level is lower than the set level, the hydraulic pressure generated by the hydraulic pump expands the piston of the hydraulic system according to the signal of the level sensor, and the piston moves linearly. One side of the lower end of the sluice, connected to the axis of rotation, and the other to the axis of rotation of the end face of the body, pushing the links together, so that the angle of both links gradually increases with respect to the axis of rotation connected to the piston, up to 170 °. As it opens, the gate closes as it descends from the fixed top gate to the bottom gate.

When fresh water is drained downstream, the piston contracts and the angle between the upper and lower rotation shafts of the body and the link arms on both sides of the sluice gradually decreases. This extinguishes and the gate is gradually opened. To explain this process more easily, the water gate opens and closes by narrowing and widening the angle of each link arm connected to the upper part of the body and the hydrologic side by the linear reciprocating motion of the piston.

In Korea, water consumption is gradually increasing due to high population density and improved living standards, while water shortages are caused by flooding, drought, and deterioration of water quality due to global climate change. There is no need to mention it again. The installation of automatic maintenance doors in river or river underwater beams can secure manpower and necessary water due to efficient water management, and it can eliminate secondary wastes of water quality by eliminating the accumulation of river wastes through the discharge of the lower part.
