Description

Technical Field

[0001] The utility model relates to the technical field of water conservancy projects, in particular to a stepped safety gate structure for water conservancy projects. Background Art

[0002] Water conservancy projects require the construction of various hydraulic structures, such as dams, dikes, spillways, sluices, inlets, channels, ferries, rafts, and fishways, to achieve their objectives. Flood control dams are a type of water conservancy project designed to intercept floodwaters and prevent soil erosion and ecological damage downstream. To facilitate water volume control, dams require intercepting gates to intercept and release water. Sluices can be categorized by their primary function: regulating gates, intake gates, sand flushing gates, flood diversion gates, tide gates, and drainage gates.

[0003] At present, when the existing gates on the market are in use, impurities such as stones, snails, and plastic bags will stick to the embedded grooves due to the silt. When the gates move up and down, they cannot self-clean and will get stuck in the gaps. In severe cases, they will get stuck, making it impossible for the gates to work normally. Moreover, long-term use will accelerate wear, affect service life, and reduce performance. In addition, traditional gates adopt a single-door structure and are not suitable for diverse usage needs.

[0026] The embodiments of the present invention will be further described below with reference to the accompanying drawings.

[0027] See also Figure 1-5A stepped safety gate structure for a water conservancy project comprises a U-shaped gate limiting frame 1, wherein a plurality of groups of clamping limiting chutes 2 are provided inside the U-shaped gate limiting frame 1, wherein a first-stage gate 4, a second-stage gate 5 and a third-stage gate 6 are clamped in the clamping limiting chutes 2 in sequence from front to back; the upper end surfaces of the first-stage gate 4, the second-stage gate 5 and the third-stage gate 6 are symmetrically connected with a pair of lifting ropes 7 and a pressurized air pipe 8; the upper ends of the lifting ropes 7 and the pressurized air pipe 8 are movable.

By adopting the above-mentioned gate structure and using staggered gates to form a stepped gate structure, the gates can be opened regionally according to usage requirements, avoiding the problem of gates being stuck. At the same time, the upper water area can be circulated, and underwater communication can be achieved to realize the bottom flow blocking structure for water surface filtration. During the specific operation process, the corresponding first-level gate 4, second-level gate 5 and third-level gate 6 can be lifted and opened separately through the lifting hoisting rope 7, thereby realizing the water extraction operation of the corresponding water layer, and the pressurized air pipe 8 can be used to supply air to the U-shaped air bag 9, thereby realizing the sealing between the U-shaped air bag 9 and the corresponding card-connected limiting slide groove 2, which has a good sealing effect.

[0028] Furthermore, three sets of reel shafts 11 are provided at the upper end of the cover plate 3. The reel shafts 11 are provided with rope reeling grooves 12 and air pipe reeling grooves 13, respectively. The lifting ropes 7 and the pressurized air pipe 8 are connected to the rope reeling grooves 12 and air pipe reeling grooves 13, respectively. The three sets of independent reel shafts 11 can subsequently control the corresponding first-level gate 4, second-level gate 5 and third-level gate 6 separately. During operation, the lifting ropes 7 are driven by the reel shafts 11, and the corresponding first-level gate 4, second-level gate 5 and third-level gate 6 can be lifted and lowered by the lifting ropes 7. The pressurized air pipe 8 can be wound by the reel shafts 11, so that the pressurized air pipe 8 can follow the lifting and lowering, thereby ensuring the safety of the pressurized air pipe 8.

[0029] Furthermore, one end of the pressurized air tube 8 wound around the air tube reel 13 is connected to the U-shaped airbag 9, and the other end of the pressurized air tube 8 is connected to an external pressurized air pump via a solenoid valve. Control between the pressurized air pump and the solenoid valve can be used to control the air supply to the pressurized air tube 8, thereby controlling the air supply to the U-shaped airbag 9.

[0034] The specific working process and principle of this utility model:

[0035] State 1: When opening the gate in the upper area, the U-shaped airbag 9 on the surface of the third-level gate 6 is first depressurized through the cooperation of the solenoid valve and the external pressurized air pump, so that the contact surface of the third-level gate 6 and the clamping limit slide 2 and the secondary gate 5 remain disengaged; the corresponding winding shaft 11 rotates in the opposite direction to lower the third-level gate 6, so that the upper gate remains open to realize the opening of the upper area of ​​the gate.

[0036] State 2: When the middle area is opened, the U-shaped airbag 9 on the surface of the secondary gate 5 and the tertiary gate 6 is depressurized through the cooperation of the solenoid valve and the external pressurized air pump, so that the secondary gate 5 and the contact surface of the clamping limit slide 2 and the primary gate 4 remain disengaged; the corresponding reel 11 rotates in the opposite direction to lower or pull up the secondary gate 5, so that the middle gate remains open to realize the opening of the middle area of ​​the gate.

[0037] State three: When opening the gate in the lower area, the U-shaped airbag 9 on the surface of the first-level gate 4 and the second-level gate 5 is depressurized through the cooperation of the solenoid valve and the external pressurized air pump, so that the contact surface of the first-level gate 4 and the second-level gate 5 and the clamping limit slide 2 remain disengaged; the corresponding winding shaft 11 rotates in the opposite direction to pull up the first-level gate 4, so that the lower gate remains open to realize the opening of the lower area of ​​the gate.
