Abstract

The present invention relates to an emergency shut-off device such as various water gates and valves installed on the inlet or outlet side of a water purification plant, a sewage treatment plant, a dam (DAM),

In the past, when floods and blackouts were not occupied by the driver's place of floodgates, various fluids suddenly entered the water purification and sewage treatment plants, causing damage to buildings and machinery. Many accidents occurred due to the loss and slow operation.

The present invention is to open and close automatically even if the driver does not stay in the place of the floodgate in the event of flood and power failure to prevent various fluids suddenly enter the water purification plant, sewage treatment plant during the flood to prevent damage to buildings and machinery In normal operation, the actuator 18 rotates by driving the motor 58 to rotate the pinion bevel gear shaft 38 to rotate the bevel gear 3 having the same tooth shape, and a trapezoidal screw inside the bevel gear 3. The stem 7 is operated up and down by the stem nut 6 when the bevel gear 3 rotates left and right to open and close the hydrologic disc connected to the stem 7.

When the gate is emergency shut off, a signal (SIGNAL) is transmitted to the actuator 18 according to the height of the fluid so that the motor 58 is powered in the same manner as in the normal operation. The pinion bevel gear 2 rotates and the bevel gear 3 rotates while the electromagnetic clutch 28 of the " The bevel gear (3) forms a four-threaded screw outside the angle of independence, so that the hydrologic disk (47) descends slowly at first due to the weight of the hydrologic gate (hydrological disk), and then suddenly accelerates due to gravity. .

At this time, when the pinion bevel gear 2 connected to the left side of the bevel gear 3 rotates sharply, the centrifugal brake 35 connected to the capping 21 rotates to slowly close the hydrologic disc 47 that descends while rotating. By preventing the damage of the sluice disk 47 to close smoothly (SMOOTH), in the event of power failure is to operate as an emergency generator and when the abnormality is to rotate the handwheel 17 to open.

Description

PERFECT SELF DESCENDING EMERGENCY GATE}

The present invention consists of a gear reducer, an electronic clutch, an impact prevention device, and a safety device so that the hydrologic disc is self-weighting. The opening and closing of the hydrologic gate is operated by electric power in a normal operation and during an emergency such as flood, earthquake, typhoon, heavy rain, power failure In case of emergency blocking of the gate, the power is supplied by the sensor to shut down the car by the weight of the emergency gate.

Conventionally, floods, earthquakes, typhoons, heavy rain, and various kinds of fluids suddenly enter the building and machinery during power outages, as well as manually opening and closing the floodgates during power outages. It was.

The present invention is to open and close automatically even if the driver does not stay in the place where the flood gates are installed during flooding and power failure to prevent the various fluids suddenly enter the water purification plant, sewage treatment plant during the flood to prevent damage to buildings and machinery In normal operation, the actuator 18 rotates by driving the motor 58 to rotate the pinion bevel gear shaft 38 to rotate the bevel gear 3 having the same tooth shape, and a trapezoid inside the bevel gear 3. By forming a screw, the stem 7 is operated up and down by the stem nut 6 in which the bevel gear 3 rotates left and right to open and close the hydrologic disc 47 connected to the stem 7. .

When the gate is emergency shut off, a signal (SIGNAL) is transmitted to the actuator 18 according to the height of the fluid surface, so that the motor 58 is powered in the same manner as in the normal operation. The pinion bevel gear 2 rotates while the electromagnetic clutch 28 of 23 drops.

In addition, the bevel gear (3) rotates and the bevel gear (3) forms a four-threaded screw outside the self-supporting angle, so that the hydrologic disk (47) slowly descends by gravity due to its own weight (the hydrologic disk). Acceleration will cause you to dive.

At this time, when the pinion bevel gear 2 connected to the left side of the bevel gear 3 rotates rapidly, the centrifugal brake 35 connected to the capping 21 rotates and the hydrologic disc 47 descends while rotating. It closes slowly so as to close smoothly while preventing the sluice of the hydrologic disc 47, and acts as an emergency generator during power outages, and when there is an error, the handwheel 17 is rotated to open.
