Background
Water conservancy and hydropower are infrastructures related to the national estimated nations, and various water conservancy gates are widely applied along with the increasing requirements of urban water use, landscape construction, environmental improvement, irrigation and power generation in China. The steel gate in the water conservancy gate is also called a steel dam gate or a bottom cross shaft turnover gate, and the steel gate has multiple advantages, such as adaptability to wide river channels, simple structure, capability of reducing middle gate piers and saving civil engineering investment, capability of closing the gate for water storage, opening the gate for flood drainage and waterlogging drainage, capability of utilizing the top of the gate for water passing, formation of the landscape effect of artificial waterfall, capability of freely adjusting the water blocking height and the like, and is generally welcomed in all aspects.
The existing steel dam comprises gate leaves positioned between gate chambers on two sides, a bottom shaft is connected to the bottoms of the gate leaves, a connecting lever is connected to the end part of the bottom shaft, the connecting lever is connected with a hydraulic machine, the hydraulic machine drives the connecting lever to rotate, so that the bottom shaft is rotated, namely the gate leaves are driven to rotate, but because a working machine room is arranged underground on the side face of a gate, the working condition is severe, the humidity is high, and the maintenance difficulty is high after a hydraulic component fails.
SUMMERY OF THE UTILITY MODEL
The utility model aims at overcoming the not enough of prior art, provide a planet transmission arm pendulum steel dam, adopt gear drive, not fragile and easy maintenance.
The purpose of the utility model is realized like this: the planetary transmission arm swing steel dam comprises a gate leaf positioned between two gate chambers at two sides, wherein the bottom of the gate leaf is connected with a bottom shaft, and the end part of the bottom shaft extends into the gate chambers and is connected with a crank arm; an arc-shaped concrete seat is fixed in the lock chamber, a fan-shaped large gear is arranged in the lock chamber, the inner arc of the fan-shaped large gear is fixed on the concrete seat, and the circle center of the fan-shaped large gear and the circle center of the bottom shaft are concentrically arranged; one end of the crank arm, which is far away from the bottom shaft, is connected with a planetary reducer, an input shaft of the planetary reducer is connected with a motor, an output shaft of the planetary reducer is connected with a pinion, and the pinion is meshed with the sector gear wheel.
Preferably, the crank arm is connected with a crank arm locking seat, and a locking hole is formed in the crank arm locking seat; the lower locking seat is connected in the lock chamber, the lower locking seat is connected with a locking oil cylinder, and the locking oil cylinder is detachably inserted into a locking hole of the crank arm locking seat.
The utility model has the advantages that: the motor drives the planetary reducer, the planetary reducer drives the pinion to rotate, and the fan-shaped big gear is fixed on the concrete seat, so that the pinion rotates on its own axis and drives the planetary reducer and the crank arm to rotate around the fan-shaped big gear, thereby driving the opening and closing of the steel dam. The utility model discloses a motor, planetary reducer, pinion, fan-shaped gear wheel etc. are mechanical transmission, consequently not fragile to easy maintenance.

Detailed Description
As shown in figures 1 to 4, the planetary transmission arm swing steel dam comprises a door leaf 7 positioned between two gate chambers 9 at two sides, the bottom of the door leaf 7 is connected with a bottom shaft 8, and the end part of the bottom shaft 8 extends into the gate chambers 9 and is connected with a crank arm 5. An arc-shaped concrete seat 10 is fixed in the lock chamber 9, a fan-shaped large gear 4 is arranged in the lock chamber 9, the inner arc of the fan-shaped large gear 4 is fixed on the concrete seat 10, and the circle center of the fan-shaped large gear 4 is concentric with that of the bottom shaft 8.
One end of the crank arm 5 far away from the bottom shaft 8 is connected with a planetary reducer 3, an input shaft of the planetary reducer 3 is connected with a motor 1, an output shaft of the planetary reducer 3 is connected with a pinion 2, and the pinion 2 is meshed with a sector gear wheel 4.
The crank arm 5 is connected with a crank arm locking seat 11, and the crank arm locking seat 11 is provided with a locking hole 13. A lower locking seat 12 is connected in the brake chamber 9, a locking oil cylinder 6 is connected on the lower locking seat 12, and the locking oil cylinder 6 can be separately inserted into a locking hole 13 of the crank arm locking seat 11.
The utility model discloses a theory of operation: the motor 1 drives the planetary reducer 3, the planetary reducer 3 drives the pinion 2 to rotate, and the pinion 2 drives the planetary reducer 3 and the connecting lever 5 to rotate around the fan-shaped big gear 4 while rotating, so that the steel dam is driven to open and close. As shown in fig. 3, when the small gear 2 rotates to the lower end of the large gear 4, and the steel dam is closed, the locking cylinder 6 extends out and is inserted into the locking hole 13 of the crank arm locking seat 11, so as to realize locking. When the steel dam needs to be opened, the locking oil cylinder 6 retracts, and when the pinion 2 rotates to the upper end of the fan-shaped bull gear 4, the steel dam is in an opening state, as shown in fig. 4.
