Description

Technical Field

[0001] The present invention relates to the technical field of hydraulic machinery, in particular to an intelligent hydraulic flat gate. Background Art

[0002] The intelligent hydraulic flat gate is a type of intelligent water conservancy equipment used to control water flow, commonly used in rainwater and sewage diversion projects. It features a high degree of automation and precise control, and uses a hydraulic system to raise and lower the gate. A hydraulic pump draws hydraulic oil from the tank and pressurizes it. This oil is then delivered to the hydraulic cylinder via a control valve, pushing the piston rod out and lifting the gate upward to open it. Conversely, a control valve redirects the flow of hydraulic oil, causing the piston rod in the hydraulic cylinder to retract, causing the gate to descend and close. Primarily used in sewage interception and pipework projects, it is installed at sewage or stormwater outlets to automatically switch and divert rainwater and sewage within the stormwater network. This allows sewage and a small amount of initial rainwater at the front of the stormwater network to enter the sewage network, preventing it from flowing into rivers, lakes, and other natural water bodies and polluting natural water bodies. It also prevents large amounts of rainwater from entering the sewage network and increasing the load on sewage treatment plants.

[0003] However, the existing intelligent hydraulic flat gates are installed by using bolts during use. During long-term operation, the equipment is often subject to continuous vibration in the environment, such as the vibration of machine operation in industrial plants, or the impact and vibration of water flow on water conservancy facilities, as well as external forces. The bolts used to fix the flat gate frame and other components are very likely to loosen. Once the bolts are loose, not only will the gate plate no longer run smoothly on the guide rail, causing vibration and abnormal noise, affecting normal opening and closing operations, but it may even cause the gate plate to be unable to close or open accurately, thereby destroying the effectiveness of the entire channel control. In serious cases, it may also cause safety accidents, threatening the safety of surrounding personnel, equipment and the environment. Summary of the Invention

[0013] (3) Beneficial effects Compared with the prior art, the present invention provides an intelligent hydraulic flat gate with the following beneficial effects: 1. This intelligent hydraulic flat gate uses the setting of movable components to deal with the loosening of bolts in the mounting holes. Under normal circumstances, the various components of the movable components are in a stable state. When the bolts tend to loosen due to factors such as vibration, the thread fit between them and the connecting rod changes, driving the connecting rod to slide in the rotating shaft. After a series of transmissions, the turntable rotates, and the internal sliding rod is used to push the fixed plate, driving the insert block to approach the bolt and insert it into the thread groove from both sides to prevent the bolt from loosening further, limit the loosening of the bolt, ensure the stability of the connection, and reduce safety hazards.

[0014] 2. This intelligent hydraulic flat gate utilizes a rotating assembly that reverses the tightening of loose bolts. When a loose bolt drives the slider, its top block, Block 1, pushes on the resistance rod, transmitting the displacement to Block 2. Block 2 then rotates the torsion ring within the retaining ring. Due to the threaded connection between the bolt and the torsion ring, the torsion ring's rotation is converted into a tightening force on the bolt, causing the bolt to reverse its rotation to offset the loosening displacement. The working principle is to utilize the movable connection and threaded fit between the various components to achieve automatic reverse tightening, preventing the bolt from continuously loosening and falling off, and maintaining the stability and reliability of the entire flat gate structure.

[0015] 3. The intelligent hydraulic flat gate uses guide rails and rollers to ensure the smooth movement of the gate plate, greatly reducing the instability such as jamming and shaking during operation, so that each opening and closing action of the gate plate can be stably repeated, reducing the probability of failure caused by unexpected shaking of the equipment, extending the overall service life of the equipment, and reducing the cost and time loss caused by frequent maintenance.

Several key components of the movable component 5 and the rotating component 6 are installed inside and on the surface of the cylindrical block 51, such as the fixed plate 52, the retaining ring 64, etc. These components are the basis for realizing the restriction and reverse tightening function when the bolt 4 is loose, thereby extending the service life of the bolt. The cylindrical block 51 is installed on the outer wall of the frame 1, and a fixed plate 52 is fixedly installed inside the cylindrical block 51.

The hydraulic cylinder 7 is used as the power source, and its telescopic action can directly drive the gate plate 2 to perform vertical lifting movement. Through the stability of the hydraulic transmission, the lifting stroke of the gate plate 2 is controllable and the force is uniform, so as to realize the precise opening and closing of the gate and meet the requirements of precise control of the opening and closing degree of the channel in different scenarios.

[0022] Finally, the surface of the turntable 53 is provided with a crescent groove 530, and the crescent groove 530 provided on the surface of the turntable 53 can be used to pull the slide bar 54 to slide horizontally when the turntable 53 rotates.

The surface of the rotating shaft 58 is provided with an arc groove 580, and the rotating shaft can be used to The arc groove 580 provided on the surface of 58 enables the rotation of the rotating shaft 58 to be driven when the sliding rod 514 slides on the surface of the rotating shaft 58. The strip groove 590 provided on the surface of the connecting rod 59 can be used to drive the sliding bar 510 to slide inside the connecting rod 59. The cross-section of the movable block 511 is triangular, and the triangular movable block 511 can be used to improve the resistance effect of the movable block 511 when the bolt 4 is loosened.

[0023] Working principle: the intelligent hydraulic flat gate is mainly composed of a frame 1, a gate plate 2, a mounting hole 3, a bolt 4, a movable component 5 and a rotating component 6. The frame 1 serves as the basic supporting structure, and the gate plate 2 arranged thereon is driven by a hydraulic cylinder 7. It slides along the guide rail 8 on the surface of the frame 1 by means of rollers to realize the lifting and opening and closing operations of the gate plate 2. The bolt 4 in the mounting hole 3 plays a connecting and fixing role, and is equipped with a movable component 5 and a rotating component 6 to ensure that it can respond in time and perform restriction and reverse tightening in the event of looseness. The hydraulic cylinder 7 installed on the top of the frame 1 is the power source for the movement of the gate plate 2. When the gate plate 2 needs to be opened, the hydraulic cylinder 7 extends and pushes the gate plate 2 fixed to it along the The guide rail 8 moves upward, and the guide rail 8 guides and supports the movement of the gate plate 2 through the rollers inside it, ensuring that the gate plate 2 can rise smoothly in the vertical direction to open the gate. Conversely, when the gate plate 2 needs to be closed, the hydraulic cylinder 7 contracts, pulling the gate plate 2 downward along the guide rail 8 until the gate plate 2 completely falls to the closed position, blocking the corresponding channel. The guide rail 8 and the roller are used to ensure the smooth movement of the gate plate 2, which greatly reduces the instability such as jamming and shaking during operation, so that each opening and closing action of the gate plate 2 can be stably repeated, reducing the probability of failure caused by accidental shaking of the equipment, extending the overall service life of the equipment, and reducing the cost and time loss caused by frequent maintenance.

[0024] When installing, the frame 1 is fixed by the bolt 4. When fixing the bolt 4, the bolt 4 needs to be installed inside the connecting rod 59 and pass through the cylindrical block 51. The bolt 4 is inserted into the inside of the connecting rod 59 to achieve interference with the triangular movable block 511. When the triangular movable block 511 is interfered with, it will move toward the inner wall of the slide bar 510. When the bolt 4 moves to the bottom end of the connecting rod 59, the movable block 511 will be reset under the action of the fixing spring 512, so that the movable block 511 is inserted into the thread groove on the surface of the bolt 4 for connection, so that the bolt 4 can be loosened by interfering with the plane at the bottom end of the movable block 511, pulling the slide bar 510 upward. Under normal circumstances, if the bolt 4 is not loose, The movable component 5 is in a relatively stable state. The fixed plate 52 on it rotates and connects the turntable 53. The sliding rod 54 inside the turntable 53 and the fixed plate 55 hinged on the outside are in a relatively static position. The insert block 57 on the connecting plate 56 at the top of the fixed plate 55 does not restrict the movement. At the same time, the connecting rod 59 slidingly connected in the rotating shaft 58 at the top of the turntable 53 maintains a stable threaded connection with the bolt 4. The sliding bar 510 inside the connecting rod 59 and the movable block 511 inside the connecting rod 59 are in a suitable initial position under the action of the fixing spring 512. The connecting shaft 513 and the sliding rod 514 also maintain the corresponding initial installation state. When the bolt 4 tends to loosen due to factors such as vibration and external force, the originally stable threaded fit between it and the connecting rod 59 is broken. Because the bolt 4 has a tendency to rotate or displace axially relative to the bolt 4, it will drive the connecting rod 59 threadedly connected thereto to produce corresponding axial sliding inside the rotating shaft 58. The axial sliding of the connecting rod 59 will act on the slide bar 510 through the strip groove 590 on its surface, so that the slide bar 510 starts to move upward synchronously under the drive of the connecting rod 59. When the slide bar 510 moves, the connecting shaft 513 fixed on its outside will drive the sliding rod 514 fixed on the inside to slide along the arc groove 580 on the surface of the rotating shaft 58. When the sliding rod 514 slides along the arc groove 580 on the surface of the rotating shaft 58, it will drive the rotation of the rotating shaft 58. This sliding fit causes the turntable 53 to start rotating inside the fixed disk 52. During the rotation of the turntable 53, the sliding rod 54 inside it will rotate along The rotation of the turntable 53 produces relative displacement, which in turn pushes the fixed plate 55 hinged thereto to retract inward, and the connecting plate 56 on the top of the fixed plate 55 moves accordingly, driving the inner plug block 57 to approach the surface of the bolt 4. Since the plug blocks 57 are provided with two pieces and are symmetrically arranged with the center line of the cylindrical block 51 as the axis of symmetry, the two plug blocks 57 can be plugged into the thread groove on the surface of the bolt 4 from both sides at the same time, forming a barrier to further loosening of the bolt 4, preventing the gate from being in an environment where there is often continuous vibration, and causing the bolt 4 to loosen over a long period of time. The loosening of the bolt 4 can cause the equipment to vibrate, make abnormal noises and other unstable conditions due to accidental structural loosening. By setting the movable component 5, the bolt 4 is restricted when loosening, making the opening and closing of the gate 2 more stable and smooth.This ensures the stable and orderly progress of the entire process, reduces production interruptions caused by equipment failures, improves equipment operation stability and safety, and extends equipment service life.

[0025] When the slide bar 510 moves as the bolt 4 is loosened, the block 1 61 fixed on its top also moves accordingly. One end of the resistance rod 62 movably connected inside the block 1 61 is pushed by the block 1 61. Since the other end of the resistance rod 62 is movably connected to the block 2 63, the resistance rod 62 will transmit the displacement of the block 1 61 to the block 2 63, driving the block 2 63 to move accordingly. The block 2 63 is fixedly installed at the bottom of the torsion ring 65, and the torsion ring 65 is rotatably connected in the retaining ring 64 inside the cylindrical block 51. When the block 2 63 moves driven by the resistance rod 62, it will drive the torsion ring 65 to rotate in the retaining ring 64. The ring 65 is threaded, so the rotation of the torsion ring 65 will be converted into a tightening force on the bolt 4, causing the bolt 4 to rotate in the opposite direction of loosening, thereby offsetting the displacement caused by its loosening, and realizing the reverse tightening operation of the bolt 4. Compared with the traditional passive anti-loosening method relying on friction, it can more actively and effectively prevent the bolt 4 from loosening, prevent the bolt 4 from continuing to loosen until it falls off, and cause structural instability. The bolt 4 is a key component of the connection structure. If it loosens and falls off, it will directly lead to the failure of the relevant connection parts of the flat gate, causing the overall structural stability to decrease or even become unstable, further enhancing the anti-loosening effect of the bolt 4 and ensuring the stability of the entire flat gate structure connection.
