Description

Technical Field

[0001] The utility model relates to the technical field of steel dams, in particular to a multi-stage telescopic steel dam. Background Technique

[0002] In the construction of water conservancy and hydropower, with the needs of urban water use, landscape construction, environmental improvement, irrigation and power generation, flap gates, sluice gates and rubber dams are widely used. However, the production of rubber dams is relatively complex, and the time for filling water (inflating) to raise the dam or discharging water (deflating) to collapse the dam during operation is relatively long, which affects rapid closure or flood discharge. Coupled with the disadvantage that rubber is prone to aging, quality accidents are likely to occur. Now, a large number of steel structure gates or flap gates appear on the market, but whether they are lifting type or horizontal type, it is difficult for a single hole to be applicable to a relatively wide river channel. The steel dam gate is a new type of adjustable and controllable overflow gate, which consists of a civil structure, a steel gate body with a fixed shaft, a hoisting device, etc. This kind of building is suitable for working conditions with a relatively wide gate opening (10 meters to 100 meters) and a relatively small water level difference (1 to 7 meters). Since it can be designed to be relatively wide, several pier gates can be omitted, so not only the structure is simple, but also a lot of civil engineering investment can be saved, and it can store water with the gate standing and discharge flood and waterlogging with the gate lying down. Therefore, a multi-stage telescopic steel dam is needed.

[0003] During water conservancy construction work, operators often use corresponding steel dams. However, in the actual use process, the steel dams cannot be adjusted, the practicability is reduced, and when the dam gates are lowered, they cannot be buffered, which may cause damage to the dam gates. Content of the Utility Model

[0004] The purpose of the utility model is to provide a multi-stage telescopic steel dam to solve the problems put forward in the above background technique that during water conservancy construction work, operators often use corresponding steel dams, but in the actual use process, the steel dams cannot be adjusted, the practicability is reduced, and when the dam gates are lowered, they cannot be buffered, which may cause damage to the dam gates.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A multi-stage telescopic steel dam, including a dam body, both sides of the top of the dam body are fixedly installed with clamping plates, a steel dam is rotatably installed between the clamping plates, a limiting plate is fixedly installed inside the steel dam, a mounting plate is fixedly installed at one end inside the steel dam, a lead screw is rotatably installed between the mounting plate and the limiting plate, a lifting dam is threadedly sleeved on the surface of the lead screw, a motor is fixedly installed at the bottom of the mounting plate, the output end of the motor penetrates through the mounting plate and is fixedly connected to the bottom of the lead screw, a fixing plate is fixedly installed inside the lifting dam, a top dam is movably installed inside the lifting dam, a storage plate is fixedly installed inside the lifting dam below the fixing plate, a pneumatic cylinder is fixedly installed on the top of the storage plate, and the output end of the pneumatic cylinder is fixedly connected to the bottom of the top dam.

[0006] Preferably, a square groove is formed at the top of the dam body, and a storage box is fixedly installed inside the square groove.

[0007] Preferably, springs are fixedly installed at equal intervals at the bottom end inside the storage box, and a pressing plate is fixedly installed at the top of the springs.

[0008] Preferably, a fixing ring located inside the storage box is fixedly installed at the bottom of the pressing plate, and the outer surface of the fixing ring is movably connected to the inner surface of the storage box.

[0009] Preferably, sliding grooves are formed on both sides of the storage box, round rods are movably installed inside the sliding grooves, and one side of the round rods is fixedly connected to one side of the fixing ring.

[0010] Preferably, fixing piers are fixedly installed at the top of the dam body, mounting blocks are rotatably installed between the fixing piers, a connecting pier is fixedly installed at one end of the steel dam, movable blocks are rotatably installed between the connecting piers, and an electric hydraulic rod is fixedly installed between the movable blocks and the mounting blocks.

[0011] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0012] During the daily use of the multi-stage telescopic steel dam, the operator starts the motor. The operation of the motor causes the lead screw to rotate. Subsequently, the lead screw drives the lifting dam to move up and down inside the steel dam. Then, the lifting dam drives the storage plate and the air cylinder to slide until the lifting dam reaches the bottom of the limit plate. At this time, the storage plate is started. The operation of the storage plate causes the top dam to slide inside the lifting dam until the top dam reaches the bottom of the fixing plate, thus completing multi-stage lifting and increasing its practicability.

[0013] During the daily use of the multi-stage telescopic steel dam, when the electric hydraulic rod drives the steel dam to slide downward between the clamping plates, the steel dam will then contact the top of the pressing plate. Subsequently, the pressing plate drives the fixing ring to slide. At this time, the pressing plate squeezes and compresses the spring, and at the same time, the fixing ring drives the round rod to slide inside the sliding groove, thereby buffering the downward impact force and reducing the damage caused to the steel dam.
