Description

Channel type hydraulic gate

Technical Field

The utility model relates to a water conservancy facility's gate structure, in particular to passageway formula hydraulic gate.

Background

The hydraulic dam is a movable dam which is relatively easy to control. It is widely applied to agricultural irrigation, fishery, ship lock, sea water tidal barrier, city river landscape engineering, small hydropower station and other constructions. The hydraulic lifting dam has scientific mechanical structure, does not block water and is not afraid of silt deposition; is not influenced by flotage; under the condition of extremely small water loss, the floating materials on the upstream can be easily washed away, so that the river water is clear; the dam is quickly put, and the flood control safety is not influenced; strong ability of fighting flood. The hydraulic dam is generally constructed by a gate plate, a gate plate lifting cylinder, a hydraulic pump station and the like. The gate plate lifting oil cylinder directly props against the back part of a movable water-blocking gate plate with a hinge at the bottom, so that the aims of lifting a dam and blocking water and lowering the dam for flood discharge are fulfilled. However, in practical use, faults of the lifting cylinder, a hydraulic pipeline related to the lifting cylinder, a hydraulic pump station and the like inevitably occur, and the faults inevitably occur in time as the service time moves backwards, so that the lifting cylinder needs to be repaired and maintained, the lifting cylinder or a hydraulic system needs to be replaced to relieve pressure during repair and maintenance, but the gate plate and the lifting cylinder are usually soaked in a river channel (water) during working, the front and the back of the gate plate are also filled with water, the main body part of the lifting cylinder is also soaked in water, the weight of one lifting cylinder reaches one ton or more, and the replacement, repair and maintenance of the underwater lifting cylinder, the unlocking cylinder and the hydraulic pipeline are simply and impossibly performed under normal conditions. Once the lifting oil cylinder and the hydraulic system are relieved, the gate plate loses support and becomes a dam-descending water-discharging state, which is not allowed for the hydraulic dam, and even if the dam is descended and water is discharged, the lifting oil cylinder, a hydraulic pipeline and the like are also pressed below the gate plate (because the lifting oil cylinder is usually arranged on the back side of the gate plate), the lifting oil cylinder cannot be replaced, repaired and maintained, and the lifting oil cylinder is a large project unless dam cofferdams are built before and after the hydraulic dam again and river water (lake water) is pumped and dried, so that the problems are very difficult in time, financial resources and water conservancy, and are always puzzled by users and manufacturers of the hydraulic dam for a long time and are also difficult problems which are not solved yet.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a simple structure, under the state that does not influence the work of gate board (including blocking water or draining), can change, repair and maintain the operation to lift cylinder, unblock hydro-cylinder and hydraulic line, and safe and reliable's a passageway formula hydraulic gate.

In order to solve the problem, the utility model discloses channel type hydraulic gate is realized through following technical scheme: the water sealing device is characterized in that an installation channel for an installer to enter from the side face of the dam body is formed below the dam body near a supporting hinge at the rear end of the gate plate, an upward through hole is formed in the top of the installation channel, a guide shaft sleeve is fixed in the through hole, a movable supporting column capable of stretching up and down is installed in the guide shaft sleeve, the bottom of the movable supporting column is connected with a piston rod of a lifting oil cylinder, a water sealing device is arranged between the guide shaft sleeve and the movable supporting column, the top face of the movable supporting column pushes the back of the gate plate, and the gate plate is jacked up or laid down along with stretching of the movable supporting column.

And a support which is pushed by the top surface of the movable support column to jack up the gate plate is arranged on the back of the gate plate.

The support is in contact with the top surface of the movable support column by adopting rolling contact.

The upper end of the supporting rod is connected to the back of the gate plate through an upper hinge, the lower end of the supporting rod is connected to the top surface of the movable supporting column through a lower hinge, the supporting rod is pushed by the top surface of the movable supporting column, and then the back of the gate plate is pushed by the supporting rod.

In order to ensure the smooth sliding of the movable supporting column in the guide shaft sleeve and prevent the inclination of the movable supporting column, guide rollers are respectively arranged at two ends of the guide shaft sleeve and abut against the outer edge of the movable supporting column to support and position the movable supporting column.

In order to ensure the smooth sliding of the movable supporting column in the guide shaft sleeve, guide rollers are respectively installed at two ends of the movable supporting column, and the movable supporting column moves up and down in the guide shaft sleeve under the guide of the guide rollers.

The bottom of installation passageway is equipped with the recessed water catch bowl that supplies ponding.

And a support pier is arranged on the dam body, and when the gate plate is laid down, the gate plate is placed on the support pier.

When the movable support column jacks up the gate plate to reach the high position and/or the middle position of the water blocking, the bottom of the movable support column is provided with a retaining device for preventing the movable support column from descending.

A hydraulic line for supplying oil to the lift cylinder is also provided in the installation passage.

According to the channel type hydraulic gate manufactured by the scheme, once the lifting oil cylinder of the gate plate of the hydraulic gate breaks down, a maintenance worker can directly enter the installation channel and abut against the movable supporting column by using the retaining device, and the lifting oil cylinder with the fault is replaced, repaired and maintained in an anhydrous environment under the condition that the gate plate is not laid down, or the lifting oil cylinder is directly replaced and repaired when the gate plate is laid down. In daily use, staff can enter the installation channel frequently to check whether the work of each lift cylinder is normal or not and whether the pipeline joint has leakage or not. And the hydraulic pipeline for supplying oil to the lifting oil cylinder is also arranged in the channel, so that the influence on the service life of the hydraulic pipeline caused by the fact that the hydraulic pipe is easily aged and is wound and impacted by sundries in a river course due to the fact that the hydraulic pipe is usually soaked in river water all the year round is avoided. The utility model discloses a can inspect at any time, repair and maintain lift cylinder and its hydraulic system, do not influence the water blocking operation of hydraulic pressure dam gate board moreover. The whole replacement and repair operation is carried out in the installation channel, so that the installation channel is very safe, and the difficult problem that the lifting oil cylinder cannot be replaced, repaired and maintained when the gate plate works is thoroughly solved.
