Technical Field
The utility model relates to a flat gate's supplementary door system that falls belongs to water conservancy project gate technical field.
Background
In the process from small opening to door closing of the winch flat gate, along with the continuous increase of the door closing resistance of the gate, the falling speed of the gate begins to slow, the elastic deformation of the steel wire rope is recovered, enough reserve door closing force is released, the gate can continuously descend, however, when the door closing speed is reduced to 0, the reserve door closing force released by the steel wire rope still cannot overcome the door closing resistance, the gate stops door closing at the moment, the door can be continuously closed after the steel wire rope continuously recovers and deforms, and the gate climbing vibration is formed in the cyclic reciprocating process. The experiment shows that the influence that the climbing shakes and cause the gate major structure is less, nevertheless to the vertical vibration influence of gate great, easily causes the situation that the gate lug is torn etc. and is unfavorable for gate normal operating, and in addition, the gate can not normally be closed the door and also climb the result that shakes and develop to a certain extent.
Chinese patent publication No. CN111236174A discloses a gate opening and closing device, in which a transverse driving device on a first traction portion drives a first traction rope to be at a working position of a small reel, a transverse driving device on a second traction portion drives a second traction rope to be at a working position of a large reel, the first traction rope is in a loose state, the second traction rope is in a tensioned state, and at this time, a winch works to drive the second traction rope to pull a gate to descend, so as to close the gate; when the flood season and the rainwater season occur, the water level of the upstream side of the dam is higher, and workers can pull the third traction rope to the pressure block in the buoyancy well by taking the second connecting seat as a starting point, and then assist the gate to be closed by changing the water level in the buoyancy well; after the rainy season is ended, can dismantle the third haulage rope, maintain and safeguard buoyancy traction unit to the supplementary gate that closes.
However, when the device is applied to the installed flat gate, the problems of large reconstruction engineering amount and high engineering cost exist.

Detailed Description
The technical solution of the present invention is further described below, but the scope of the claimed invention is not limited to the described.
As shown in fig. 1 and 2, the utility model provides an auxiliary door system that falls of plate gate, including plate gate 1, power component 3, control assembly 5 and auxiliary door assembly 6 that falls, power component 3 passes through the hoist cable and gate lug 2 is connected with plate gate 1's top, install load detection subassembly 4 on the hoist cable, auxiliary door assembly 6 that falls is connected with plate gate 1's top, control assembly 5 and power component 3, load detection subassembly 4 and auxiliary door assembly 6 electric connection that falls. On the basis of installing flat gate 1, only need install load determine module 4, control assembly 5 additional and supplementary door subassembly 6 that falls, can reduce or eliminate and climb and shake, avoid flat gate 1 to appear gate lug 2 because of climbing to shake and tear, the condition of flat gate 1 can not normally close the door, and the transformation engineering volume is little, and engineering cost is low.
The power assembly 3 is mounted on a fixed building.
The power assembly 3 comprises two winches.
The load detection component 4 is a load sensor.
The control component 5 is a central processing unit or a PLC.
The auxiliary drop door assembly 6 is mounted on a fixed building.
The auxiliary drop door assembly 6 is located on the center line of the flat gate 1.
The auxiliary door falling assembly 6 is a screw rod lifter, and the screw rod lifter is driven by a motor.
The motor is a stepping motor or a servo motor. The rotating speed of the motor is conveniently controlled by the central processing unit or the PLC.
The supplementary door system that falls of flat gate, its theory of operation as follows:
before the flat gate 1 is in formal operation, the load sensor is installed on a sling, the holding force (namely, the force applied to the sling by the flat gate 1) change of the flat gate 1 in the door falling process is measured through trial operation, a relation curve of the holding force and the gate opening degree is fitted, and finally the relation curve is input into a central processing unit to be used as a gate falling reference curve in the formal operation of the flat gate 1.
In the process of falling the flat gate 1, the central processing unit checks the falling speed of the flat gate 1 through the rotating speed of the winch, then the rotating speed of the motor is controlled, so that a screw rod (an executing part) in the screw rod lifter and the flat gate 1 fall synchronously, the vibration generated in the process of falling the flat gate 1 is reduced, and the quick response can be made when the flat gate 1 is about to climb.
Meanwhile, in the process that the flat gate 1 falls, the holding force on the sling is detected in real time through the load sensor and transmitted to the central processing unit, the central processing unit compares the real-time data of the holding force with a reference curve, if the holding force of the gate is not enough to enable the flat gate 1 to normally fall to a position under a certain opening degree, the central processing unit calculates the required additional force, then the screw rod is controlled to move downwards, a downward compensation force is applied to the flat gate 1, and the flat gate 1 is enabled to normally fall to the position.
