Description

Technical Field

[0001] The present invention relates to the technical field of radial gate opening and closing, and in particular to a method for opening and closing a radial gate using a hydraulic gate hoist and an opening and closing system thereof. Background Art

[0002] The radial gate is a gate with a partially curved surface of a cylinder as the retaining surface. The support hinge of its support arm is located at the center of the circle, and the gate rotates around the support hinge when opening and closing. The radial gate consists of three parts: a rotating gate body, an embedded component, and an opening and closing device. The radial gate has no gate groove, a small opening and closing force, and good hydraulic conditions. It is widely used as a working gate on various types of waterways.

[0003] The main body of the radial gate consists of four parts: the gate leaf, the support arm, the support hinge and the water stop device. The gate leaf is an arc-shaped pressure surface of a nearly plane system, which is composed of an arc panel and a beam grid system of primary and secondary beams. The gate leaf beam grid is arranged in two forms: the main crossbeam system and the main longitudinal beam system. The main crossbeam system is mostly used for open-top or large-width-height radial gates; the main longitudinal beam system is often used for high-head submerged radial gates with small width-height ratios. The support arm of the radial gate supports the gate leaf and transmits the radial force to the support hinge shaft. The extremely narrow radial gate is also made into a support arm frame, which is called a single-arm radial gate. The support arm is divided into a straight support arm and an inclined support arm. The latter is mostly used for open-top radial gates with large orifice width. Each side of the support arm is mostly composed of two pressure-bearing members (columns). For those with a larger height, three pressure-bearing members are also used on each side. The support hinge is composed of a hinge connecting the support arm, a fixed shaft and a fixed hinge seat. The hinge seat is firmly connected to the buried components on the building and transmits force to the foundation. The support hinge should be flexible and its installation position should be higher than the downstream water surface. The support hinge has cylindrical hinge and conical hinge. The cylindrical hinge has a relatively simple structure, is easy to manufacture and install, and is widely used; the conical hinge is mostly used on large-span (wide) exposed top type radial gates.

[0004] The embedded components include side water stop seat, bottom sill water stop seat, top water stop device and support hinge seat bearing components, which are generally embedded in the surface of the relevant parts of the concrete to play a role in water stop and load bearing. The water stop device of the small and medium-sized arc gates and the arc gates with low total water pressure uses general rubber, and the submerged high-pressure arc gates use special sealing rubber. The support hinge seat bearing components of the exposed arc gate are generally embedded in the cantilevered bracket of the gate pier; the support hinge seat bearing beams of the submerged arc gate are either directly embedded in the large volume of concrete or inserted into the side wall at both ends for anchoring.

[0005] The opening and closing force of the arc gate is small, and the movement trajectory of the lifting point is an arc. The top-exposed or relatively wide and high arc gates usually use two lifting points, and the opening and closing equipment usually adopts a one-door-one-machine layout. According to the structure of the building, the opening and closing form of the arc gate is usually adopted: the lifting point is set in front of the door leaf panel, using a wire rope winch or a plate chain hoist; the lifting point is set on the beam system or support arm behind the door leaf panel, and a wire rope winch and a hydraulic hoist can be used. The cylinder of the hydraulic hoist of the arc gate is generally made to be swingable to achieve a compact layout and reduce the weight of the equipment.

[0006] In the prior art, the publication number "CN215402775U" discloses a drum-type anti-snag device for the hydraulic hoist cylinder of a radial gate, which includes a winch, a wire rope, a fixed pulley block and a basket bolt. The winch is arranged on the side wall where the radial gate is installed and is higher than the hanging point of the hydraulic hoist cylinder. A fixed pulley block is arranged on the upstream side wall of the hanging point of the hydraulic hoist cylinder. The wire rope on the winch passes through the pulley block and is connected to the lifting ear at the front end of the outer wall of the hydraulic hoist cylinder through the basket bolt. The winch drives the wire rope and the hydraulic hoist to run synchronously. The drum-type anti-snag device of the utility model is easy to operate, safe and reliable, does not affect the flow state of water, and can be freely retracted and released as the cylinder piston rod contracts.

[0007] However, the existing technology still has major deficiencies, such as:

[0008] In the above-mentioned device and the prior art, during the opening and closing process of the radial gate, the lack of assisting force causes wear on the inner side of the radial gate. When the radial gate is in a static opening and closing state, the lack of assisting force at the bottom of the radial gate can easily cause excessive instantaneous load on the driving structure, affecting the normal opening and closing of the radial gate and the opening and closing effect of the radial gate.

[0044] The gate hydraulic opening and closing rotating unit also includes a reinforcement part, which includes a primary reinforcement rib 24.

Secondary reinforcement ribs 25 are arranged on both sides of the rotating arm 23, and the secondary reinforcement ribs 25 are also fixed to one side of the rotating block 22.

[0045] In this embodiment, the movable end of the hydraulic cylinder body 6 extends to drive part of the arc gate 4 to slowly lift along the inside of the arc slide 11. During the rotation and lifting process of the arc gate 4, the inner side of the arc gate 4 will fit with the power-assisting wheel 17. The power-assisting wheel 17 will reduce the wear of the arc gate 4 and the inner side of the arc slide 11, thereby ensuring the smooth opening and closing of the arc gate 4.

[0046] The gate closing hydraulic impedance buffer unit is arranged in the inner area of ​​the arc slide 11, and is used to reduce the pressure on the arc gate 4 area when the arc gate 4 is hydraulically closed, so as to ensure that the arc gate 4 slides smoothly inside the arc slide 11;

[0050] Embodiment 2:

[0051] Based on the first embodiment, in this embodiment, it is considered that when the radial gate is in static opening and closing, the lack of power at the bottom of the radial gate can easily lead to excessive instantaneous load on the driving structure, affecting the normal opening and closing of the gate, and affecting the opening and closing effect of the gate. Therefore, in this embodiment, a gate starting power unit is provided, which is used for external power starting when the gate is opened, so as to avoid the above problem;

[0052] A gate starting power-assisting unit is arranged at the bottom of the arc gate 4 .

[0053] The gate starting assist unit includes a buoyancy part, which includes a buoyancy box 7. The buoyancy box 7 is installed at the bottom of the arc gate 4. A plurality of independent partition chambers are arranged in the buoyancy box 7. An air intake valve pipe 71 is installed on the outside of the buoyancy box 7. The air intake valve pipe 71 is independently connected to the partition chambers in the buoyancy box 7.

[0054] The gate start-up assist unit comprises a water blocking part, which comprises a driving shaft 81 . The driving shaft 81 is installed on the inner side of the adjacent embedded gate platform 1 , and a water retaining arc plate 8 is installed on the rotating end of the driving shaft 81 .

[0055] In this embodiment, when the water storage chamber inside the buoyancy box 7 is filled with water, the bottom of the arc gate 4 will be supported by the buoyancy of the water body. When the rotating shaft 51 rotates, the buoyancy of the water body will assist the rotating shaft 51 to lift the arc gate 4 smoothly from the water body. When the arc gate 4 gradually leaves the water body, the water in the water storage chamber inside the buoyancy box 7 can be quickly discharged through the air inlet valve pipe 71, further ensuring the smooth opening of the arc gate 4.

[0056] A method, based on the hydraulic hoist system for opening and closing a radial gate, comprises the following steps:

[0057] S1: During the rotation and lifting process of the radial gate 4, the inner side of the radial gate 4 will fit with the booster wheel 17, and the booster wheel 17 will reduce the wear of the radial gate 4 and the inner side of the curved slideway 11, ensuring that the radial gate 4 is opened and closed smoothly;

[0058] S2: The buoyancy of the water body will assist the rotating shaft 51 to smoothly lift the radial gate 4 from the water body. When the radial gate 4 gradually leaves the water body, the water in the water storage cavity inside the buoyancy box 7 can be quickly discharged through the air inlet valve pipe 71, further ensuring the smooth opening of the radial gate 4.

[0059] S3: The booster wheel 17 installed on one side of the buffer spring sheet 13 will press against one side of the arc gate 4 to reduce the pressure effect on one side of the arc gate 4 and ensure smooth resetting of the arc gate 4 during the closing process.

[0060] Working principle: During the use of the device, the embedded gate platform 1 is installed inside the preset waterway. When the water in the preset waterway needs to be opened, the operator can drive the rotating shaft 51 to rotate. When the rotating shaft 51 rotates, the hydraulic cylinder body 6 can be driven to rotate through the movable block 61. During the rotation of the hydraulic cylinder body 6, the movable end of the hydraulic cylinder body 6 can be extended to drive the arc gate 4 part to be slowly lifted along the inside of the arc slide 11. During the rotation and lifting process of the arc gate 4, the inner side of the arc gate 4 will fit with the power-assisted wheel 17, and the power-assisted wheel 17 will reduce the wear of the arc gate 4 and the inner side of the arc slide 11, ensuring the smooth opening and closing of the arc gate 4;

[0061] When the arc gate 4 is opened, in order to reduce the rotation torque load of the rotating shaft 51 under the static state of the arc gate 4, water can be quickly injected through the buoyancy box 7 at the bottom of the arc gate 4, and the water flow in the external waterway quickly enters the buoyancy box 7 through the air inlet valve pipe 71 on the surface of the buoyancy box 7. The buoyancy box 7 is provided with multiple groups of independent partitioned water storage chambers. When the water storage chamber inside the buoyancy box 7 is full of water, the bottom of the arc gate 4 will be supported by the buoyancy of the water body. When the rotating shaft 51 rotates, the buoyancy of the water body will assist the rotating shaft 51 to lift the arc gate 4 smoothly from the water body. When the arc gate 4 gradually leaves the water body, the water in the water storage chamber inside the buoyancy box 7 can be quickly discharged through the air inlet valve pipe 71, further ensuring the smooth opening of the arc gate 4.

[0062] When it is necessary to block and close the water in the preset waterway, the operator can drive the hydraulic cylinder 6 to rotate by driving the rotating shaft 51. During the rotation of the hydraulic cylinder 6, the movable end of the hydraulic cylinder 6 can be extended to drive the arc gate 4 to slowly reset along the inside of the arc slide 11. The arc gate 4 will be continuously inserted into the water inside the preset waterway during the resetting process. When the arc gate 4 is inserted into the water, it will be subject to the pressure from the water. In order to reduce the pressure effect on the closing of the arc gate 4, due to the support of the buffer spring sheet 13, the power-assisted wheel 17 installed on one side of the buffer spring sheet 13 will be tightly fitted on one side of the arc gate 4, so as to reduce the pressure effect on one side of the arc gate 4 and ensure the smooth resetting of the arc gate 4 during the closing process.

[0063] When the arc gate 4 is rotated and closed, in order to further reduce the water pressure on the arc gate 4, the operator can open the water retaining arc plate 8 through the driving shaft 81 during the closing process of the arc gate 4, so that the water retaining arc plate 8 is rotated and inserted into the water inside the preset waterway, thereby partially blocking the water inside the preset waterway. When the water inside the preset waterway is partially blocked, the water pressure on the arc gate 4 will be reduced, thereby further ensuring the closing effect of the arc gate 4.

[0064] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
