Description

Technical Field

[0001] This utility model relates to the field of gate technology, and in particular to a bidirectional rotary gate. Background Technology

[0002] In water conservancy projects and waterway construction, bidirectional rotary gates are key equipment for switching between water blocking and navigation functions. Their adaptability to operating conditions, operational stability, and ease of maintenance directly affect the overall efficiency and safety of the project.

[0003] Shortcomings of existing technology: 1. Traditional bidirectional rotary gates often employ separate drive and positioning structures, lacking a coordinated adaptation mechanism. Power transmission is prone to losses, leading to unstable gate leaf rotation and significant positioning deviations during operational transitions. This not only affects the water-blocking and sealing effect but may also pose a threat to navigation safety.

[0004] 2. The existing gate's water-stopping structure and dredging device are mostly independent operating modes. When blocking water, silt easily accumulates in the contact area between the water-stopping embedded part and the gate leaf, affecting the sealing performance; before navigation, a separate dredging procedure needs to be started, which is cumbersome and time-consuming, reducing the efficiency of switching operating conditions.

[0005] 3. During the maintenance of traditional gates, there is a lack of a dedicated gate leaf locking and positioning structure. It is necessary to build an additional temporary support device to fix the gate leaf, which is not only complicated and time-consuming, but also poses a high safety risk. Utility Model Content

[0006] To address the aforementioned problems, this utility model provides a bidirectional rotary gate. This gate solves the problems of unstable drive, conflict between sealing and dredging, and inconvenient maintenance of traditional gates through integrated drive-positioning and water-stopping-dredging linkage structures.

[0007] To solve the above problems, the technical solution adopted by this utility model is as follows: A bidirectional rotary gate includes a river channel. Crank arms are rotatably connected to both banks of the river channel. An arc-shaped gate leaf spanning the river channel is fixedly installed on the front side of each pair of crank arms via a pair of connecting plates. An arc-shaped bottom groove adapted to the arc-shaped gate leaf is provided at the bottom of the river channel. A first and a second opening / closing connecting lug are respectively installed at the top ends of each crank arm. Opening / closing mechanisms capable of rotating the crank arms are installed on both banks of the river channel. The opening / closing mechanism connects with the first opening / closing connecting lug to achieve the water-blocking and navigation states of the arc-shaped gate leaf, and connects with the second opening / closing connecting lug to achieve the maintenance state of the arc-shaped gate leaf. Locking seats capable of locking the position of the arc-shaped gate leaf are also installed on both banks of the river channel.

[0008] Preferably, the opening and closing mechanism includes an opening and closing machine base fixedly installed on both banks of the river. A horizontally arranged opening and closing machine is fixedly installed on the top of the opening and closing machine base. The opening and closing machine is a hydraulic cylinder. The telescopic end of the opening and closing machine is an opening and closing machine shaft. A pin is installed at the end of the opening and closing machine shaft, which can be detachably connected to a first opening and closing connecting lug or a second opening and closing connecting lug.

[0009] Preferably, the crank arm includes a crank arm main board, a main shaft sleeve is fixedly installed on the crank arm main board, a shaft sleeve reinforcing plate is installed around the main shaft sleeve, a rotating seat is fixedly installed on both banks of the river channel, a rotating shaft is fixedly connected to the rotating seat, and the end of the rotating shaft is inserted into the corresponding main shaft sleeve.

[0010] Preferably, the sidewall of the crank arm main board is fixedly connected with multiple main board ribs radiating from the main shaft sleeve. The top two ends of the crank arm main board are fixedly installed with a first ear seat connecting plate and a second ear seat connecting plate. Multiple ear seat connecting ribs are fixed between the sidewall of the first ear seat connecting plate and the second ear seat connecting plate and the crank arm main board.

[0011] Preferably, a locking hydraulic cylinder is installed on the locking seat, and a locking sleeve is provided on both the first and second opening and closing connecting lugs, the locking sleeve being inserted and locked by the telescopic end of the locking hydraulic cylinder.

[0012] Preferably, a shovel plate is installed at the lower end of the arc-shaped door leaf.

[0013] Preferably, side water-stopping components and bottom water-stopping components are installed on both sides and the bottom of the river channel, respectively, and the side water-stopping components and bottom water-stopping components are adapted to the arc-shaped door leaf to achieve sealing.

[0014] The beneficial effects of this utility model are as follows: 1. An innovative symmetrical layout of "2 hoists + 2 rotating shafts + 2 locking seats" is adopted. The connecting plate connects the arc-shaped gate leaf with the rotating seat and hoist base, forming an integrated structure of power transmission, rotation guidance and maintenance positioning. The hoists provide power for switching working conditions, the rotating shafts ensure stable rotation of the gate leaf, and the locking seats realize maintenance positioning. The three work together to solve the problems of "unstable drive and positioning deviation" when switching working conditions of traditional gates. In addition, the crank arm and connecting plate have high structural strength, which improves the overall structure's resistance to water flow impact.

[0015] 2. Design a linkage structure of "1 set of bottom water-stop embedded parts + 1 set of side water-stop embedded parts + 1 set of silt-removing device": In the water-blocking mode, the two types of water-stop embedded parts are precisely fitted with the gate leaf to achieve a seal, and the silt-removing plate cleans the silt synchronously with the rotation of the arc-shaped gate leaf, avoiding silt from getting stuck in the water-stopping structure; in the lowering mode, as the gate leaf detaches from the water-stop embedded parts, the silt-removing device is lowered with the arc-shaped gate leaf for secondary silt removal, solving the technical pain points of traditional gates where "sealing and silt removal conflict and silt removal is required before navigation".

[0016] 3. For maintenance and repair work, a matching structure of two locking seats and arc-shaped gate leaves is configured. The locking seats can directly and rigidly limit the gate leaves without the need for additional support devices. This structure solves the problem of "difficulty in fixing the gate leaves and high safety risks" during the maintenance of traditional gates. Moreover, the matching design of the locking seats and gate leaves ensures positioning accuracy and improves maintenance efficiency. Attached Figure Description
