Description

Technical Field

[0001] The utility model relates to a locking mechanism used in water conservancy projects, in particular to a movable diversion pier locking mechanism. Background Art

[0002] In the water conservancy and hydropower industry, the locking mechanism is a load-bearing component widely used in hydraulic metal structure equipment, such as gate and hoist locking device. As a component of the equipment, whether its layout is proper or not is related to the normal and safe operation of the equipment and the entire project. Therefore, a safe and effective locking method is becoming more and more important and operability.

[0003] In some mainstream rivers with navigation functions, in order to prevent ships from being impacted by tributary water and deviating, a method of setting fixed or movable diversion piers at the estuary where the tributaries merge into the mainstream river is often used to improve the flow state and reduce the direct impact of tributary water on ships. A Chinese patent discloses a hydraulically driven self-floating movable diversion pier (CN117488728A), which is mainly composed of a shorter fixed diversion pier and a hydraulically driven pontoon. The fixed diversion pier is used for diversion in the dry season, and the combination of the hydraulically driven pontoon and the fixed diversion pier is used for diversion in the flood season, which can effectively reduce the impact of tributary water. Although it has many advantages such as reducing the height of the fixed diversion pier to improve the river landscape and low construction cost, it also has the problem that the diversion pier cannot be locked when lying flat and is easily impacted and shaken by the riverbed water flow, thus posing certain safety hazards. Utility Model Content

[0004] The utility model aims to solve the problems existing in the above-mentioned background technology and provide a movable diversion pier locking mechanism, which can not only realize the reliable fixation of the diversion pier after lying flat but also is easy and labor-saving to operate, thereby saving the manpower cost and management cost of the normal operation of the diversion pier.

[0005] The technical solution adopted by the utility model is:

[0006] A movable guide pier locking mechanism comprises a fixed guide pier, a movable guide pier, a support hinge device, an active rod, a limiting sleeve, and a transmission rod, wherein the fixed guide pier is provided with movable guide piers at regular intervals along its axial direction, the movable guide pier is hinged to the fixed guide pier through the support hinge, and a first locking block is built-in and fixed in the movable guide pier; the support hinge device is divided into a first support hinge device and a second support hinge device, the water-facing side surface of the fixed guide pier is provided with a first support hinge device, and the bottom surface of the fixed guide pier is provided with a second support hinge device; the active rod is hinged to the first support hinge device, the limiting sleeve is hinged to the second support hinge device, and the transmission rod is hinged to the active rod after passing through the limiting sleeve; the contact end of the transmission rod and the first locking block is provided with a second locking block, and the contact end of the transmission rod and the water-facing side surface of the fixed guide pier is provided with a spring, the transmission rod reciprocates under the compression and reset of the spring, and then drives the second locking block at the other end to perform locking and unlocking actions.

[0007] Furthermore, the fixed guide pier is a reinforced concrete structure.

[0008] Furthermore, the movable guide pier is a pontoon structure that can rotate around a support hinge as the water level changes to achieve self-floating and sinking, and the first locking block built into the pontoon structure is a wedge-shaped locking block.

[0009] Further, the first hinge device includes a hinge seat and a hinge shaft, and the hinge seat is welded and fixed to the embedded part on the water-facing side of the fixed guide pier; the active rod includes a first round steel rod and a first single connecting plate, the first round steel rod is welded to the first single connecting plate, and the first single connecting plate is hinged to the hinge seat through the hinge shaft, so that the active rod can rotate around the hinge shaft; the second hinge device includes a hinge seat and a hinge shaft, and the hinge seat is welded and fixed to the embedded part located on the bottom surface of the fixed guide pier; the limit sleeve includes a limit tube and a second single connecting plate, the limit tube is welded to the second single connecting plate, and the second single connecting plate is hinged to the hinge seat through the hinge shaft, so that the limit sleeve can rotate around the hinge shaft; the transmission rod includes a second round steel rod, a second locking block, a double connecting plate and a connecting shaft, the second round steel rod is respectively welded with a second locking block and the spring at both ends, and is welded to the double connecting plate in the middle, and the double connecting plate is hinged to the first single connecting plate through the connecting shaft, so that the active rod and the transmission rod can rotate around the hinge shaft.

[0010] When the water level of the tributary is high during the flood season, the active rod is manually pushed toward the tributary side, thereby driving the transmission rod to unlock. The movable diversion pier is subjected to the greater buoyancy and overcomes its own gravity to rotate to an upright state.

[0011] When the water level of the tributary is low during the dry season, the movable diversion pier rotates to a horizontal state because its own gravity is greater than the buoyancy in the water. At this time, the spring at one end of the transmission rod is compressed, and the first locking block fixed inside the movable diversion pier and the second locking block at the other end of the transmission rod automatically form an interlocking state.

[0012] The beneficial effects of the utility model are:

[0013] 1. Simple structure, easy installation, wedge locking principle, high reliability and good safety;

[0014] 2. Using the lever principle, the operation is labor-saving and simple, and the locking can be realized automatically, and manual operation is required only for unlocking;

[0015] 3. Low cost, low labor cost and maintenance cost during operation;

[0016] 4. Most of the components are placed underwater, with only the transmission rods higher than the platform, which has a good landscape effect and is convenient for further landscape transformation. BRIEF DESCRIPTION OF THE DRAWINGS
