Description

Gate with locking structure for water conservancy

Technical Field

As shown in fig. 2, the air inlet pipe 5 and the sealed air bag 30 are connected to the air pump through a pipe provided with an electromagnetic valve;

the air in the air inlet pipe 5 or the sealed air bag 30 can be pumped out at any time through the matching of the air pump and the electromagnetic valve, so that the sealing and attaching effect of the sealed air bag 30 and the inner wall of the packaging groove 23 can be relieved at any time, and the locking block 9 and the driving gear 3 are contacted at any time.

The working principle is as follows:

firstly, two chains respectively penetrate through the through holes 26 on the corresponding side, the two ends of each chain are respectively connected with the winding rod 29 and the hanging ring 24, then the brake opening motor 28 is started to enable the winding rod 29 to rotate rapidly, the chains can be wound or unwound rapidly, and then the whole gate plate 2 is enabled to move up and down along the inner wall of the packaging groove 23 under the coordination of gravity; the air in the air inlet pipe 5 and the air in the sealed air bag 30 is pumped out through the matching of the air pump and the electromagnetic valve, so that the sealed joint of the sealed air bag 30 and the inner wall of the packaging groove 23 can be released, the piston 7 can be pulled upwards along the inner wall of the sealed cavity 6 under the action of negative pressure, the piston 7 can be moved to pull the locking block 9 upwards through the connecting rod 8 to be disengaged from the driving gear 3, so that the locking of the driving gear 3 can be released, the locking block 9 can be engaged with the driving gear 3 at any time through injecting air into the air pump in the same way, the driving gear 3 is locked, the driving gear 3 is prevented from rotating under the matching of the driving gear pressing plate 4, and the up-and-down movement of the flashboard 2 can be prevented, so that the flashboard 2 is locked;

at this time, the gate plate 2 drives the driving gear 3 to move upwards under the lifting of the gate opening motor 28, and the driving gear 3 is rotated under the matching of the driving gear pressing plate 4 which is continuously meshed, and the driving gear 3 does not drive the first driven gear 11 to rotate through the pawl structure 12 in the lifting process, namely the material stirring roller 10 is not driven to rotate during lifting, so that the driving gear 3 can drive the material stirring roller 10 to rotate under the matching of the pawl structure 12 when the gate plate 2 is lowered, and the two material stirring rollers 10 move towards the two sides from the bottom of one side at the moment, namely, floating objects at the bottom of the gate plate 2 can be stirred away when contacting the water surface, and the situation that the material stirring roller 10 cannot be tightly attached to the folding assembly 20 due to the fact that the floating impurities are left at the bottom of the material stirring roller 10 is avoided;

after the gate is opened, because water flow continuously carries silt, broken stone and the like to pass through the packaging groove 23, silt is remained in the packaging groove 23 and at the top of the folding assembly 20 to influence the attachment of the bottom of the gate plate 2 and the folding assembly 20, when the gate plate 2 is lowered, the driving gear 3 can continuously rotate due to the matching of the driving gear 3 and the driving tooth pressing plate 4, the driving gear 3 can continuously drive the second driven gear 13 to rotate, the second driven gear 13 continuously and intermittently pushes the mounting sleeve 14 to rotate under the matching of the transmission mechanism 15, and the mounting sleeve 14 can drive the packaging sleeve 16 and the clockwork spring 17 to rotate towards one direction through the rotation; meanwhile, due to the pulling force of the limiting spring 22 and the gravity factors of the folding assembly 20 and the bottom plate 21, the packaging sleeve 16 and the clockwork spring 17 are pulled by the lifting rope 19 and the winding roller 18 to rotate in opposite directions, so that the elastic force recovery performance of the clockwork spring 17 is rapidly increased, the rotation speed of the mounting sleeve 14 is indirectly lower than that of the second driven gear 13 under the limitation of the limiting spring 22, the second driven gear 13 pushes the pawl assembly 153 and the sliding block to slide along the inner wall of the sliding groove 151 and continuously presses the positioning spring 152 to increase the elastic force recovery performance of the positioning spring 152 until the continuously rotating second driven gear 13 pushes the pawl assembly 153 to separate from the two, at the moment, the lifting rope 19 is rapidly wound by the packaging sleeve 16 and the winding roller 18 under the elastic force recovery effect of the clockwork spring 17, and the bottom plate 21 is driven to move downwards under the elastic force recovery effect of the limiting spring 22;

due to the elastic force recovery action of the clockwork spring 17, the supporting plate 201 can be continuously pulled through the packaging sleeve 16, the winding roller 18 and the lifting rope 19, so that the supporting plate 201, the first turnover plate 204 and the second turnover plate 205 are unfolded during the opening of the gate to prevent a large amount of broken stones from entering the interior of the folding groove 203, and the folding assembly 20 and the bottom plate 21 can reciprocate up and down while the gate 2 is lowered, so that a small amount of broken stones falling into the interior of the packaging groove 23 can be pushed out at any time.
