Description
Technical Field
[0001] This utility model relates to the field of water conservancy equipment technology, specifically to a hydraulic control system for gate flaps. Background Technology
[0002] Around the turn of the 20th century, the rise of small hydropower and the increasing demand for urban river landscape management led to the emergence of hydraulically controlled flap gates. These gates, requiring no additional power, offering convenient operation, and being low-cost, perfectly met the needs of such projects and became a popular choice for small and medium-sized water conservancy projects. Currently, a large number of these gates are still in operation in small and medium-sized water conservancy projects. Their core principle is to automatically open and close the gates by balancing water flow pressure and torque to regulate water levels. Initially, they effectively met the needs of hydropower regulation and maintaining landscape water levels.
[0003] However, as the usage time increases, the gates suffer from water erosion, siltation, water corrosion, wear and rust on rotating parts, and aging of sealing structures, causing the automatic flip-closing function to fail and the gates to be unable to open and close autonomously. In order to ensure the normal operation of the project, staff need to manually operate the gates to open and close them. However, manual operation not only requires a large investment of manpower, but also is difficult and inefficient in turbulent water flow or in bad weather conditions, and there are also certain safety hazards, which brings great inconvenience to the daily management and operation of water conservancy projects.
[0004] To address these issues, we provide a hydraulic control system for gate flaps. Utility Model Content
[0005] The purpose of this utility model is to provide a hydraulic control system for gate flaps to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution: The hydraulic control system for gate flaps includes a dam body. Several gate support piers are fixedly connected to the bottom of the dam body. A working bridge for personnel to walk is built between the upper ends of the gate support piers. Several gates are also installed in the dam body. The gates are spliced together to form a water-blocking structure. The gate support piers are equipped with opening and closing components for controlling the opening and closing of the gates. A bank-side machine room is built on one side of the dam body. The bank-side machine room is equipped with a control device for controlling the opening and closing components. The bank-side machine room is also equipped with a monitoring component for monitoring the water level.
[0007] As a further embodiment of this utility model: the opening and closing assembly includes a third rotating seat, which is fixedly connected to the bottom step of the gate support near the gate. A fixed support rod is rotatably connected to the third rotating seat, and the end of the fixed support rod away from the third rotating seat is fixedly connected to the gate. The dam body is provided with hydraulic cylinder supports on one side of the gate support, and each hydraulic cylinder support is provided with a push-pull assembly for pushing the gate to open and close.
[0008] As a further embodiment of this utility model: the push-pull assembly includes a second rotating seat, which is fixedly connected to the inclined surface at the upper end of the cylinder support. A hydraulic cylinder is rotatably connected inside the second rotating seat. A first rotating seat is fixedly connected to the upper end of the gate plate. The first rotating seat is rotatably connected to the output end of the hydraulic cylinder.
[0009] As a further embodiment of this utility model: the control device includes a hydraulic pump station and hydraulic oil pipes. The hydraulic pump station is located in the shore engine room. The hydraulic pump station is connected to the hydraulic cylinder through the hydraulic oil pipes to control the extension and retraction of the hydraulic cylinder.
[0010] As a further embodiment of this utility model: the monitoring component includes a monitor, which is installed on the top of the machine room on the shore for monitoring the dam area, and a level gauge for detecting the water level is also provided on one side of the dam.
[0011] As a further improvement of this utility model: the shore-side machine room is equipped with an electrical control box, and the monitor, level gauge and hydraulic pump station are all electrically connected to the electrical control box.
[0012] As a further improvement of this utility model, a reinforcing rib is fixedly connected to the side of the gate plate near the gate plate support.
[0013] Compared with the prior art, the beneficial effects of this utility model are: This invention utilizes two sets of hydraulic cylinders, each adapted to the gate size and water head, installed at both ends of each flap gate. These cylinders, combined with a hydraulic pump station and connecting oil pipes inside a riverside building, form a hydraulic system. By electrically controlling the oil circulation, it directly solves the problem of automatic opening and closing failure caused by component wear and aging in the original gates. This ensures stable and controllable water release during the flood season and water storage during the dry season, eliminating reliance on single hydraulic automatic control. It also provides three modes: on-site operation, remote video control via mobile phone, and automatic water level control via level gauge. This significantly reduces reliance on manual labor and operational safety risks. Furthermore, the hydraulic pump station has good protection, and the system is compatible with different gate specifications, which can extend equipment life and improve the efficiency and intelligence level of water conservancy project management.

Detailed Implementation
[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0019] Please see Figure 1 In this embodiment of the utility model, the hydraulic control system for the gate flap includes a dam body 1. Several gate support piers 5 are fixedly connected to the bottom of the dam body 1. A working bridge 13 for personnel to walk on is erected between the upper ends of the gate support piers 5. Several gates 12 are also provided inside the dam body 1. The gates 12 are spliced together to form a water-blocking structure. During the dry season, the gates 12 can be kept closed by their own structure in conjunction with the hydraulic system to intercept water flow and maintain the water level in the river. The gate support piers 5 provide stable support for the gates 12 and the working bridge 13 above them. The working bridge 13 facilitates on-site operation, equipment maintenance and other work for personnel, ensuring stable operation and convenient management of the system.
[0020] Please see Figure 2 and Figure 3The gate support 5 is equipped with an opening and closing assembly for controlling the opening and closing of the gate 12. The opening and closing assembly includes a third rotating seat 16, which is fixedly connected to the bottom step of the gate support 5 near the gate 12. A fixed support rod 15 is rotatably connected to the third rotating seat 16, and the end of the fixed support rod 15 away from the third rotating seat 16 is fixedly connected to the gate 12. Hydraulic cylinder supports 3 are cast on one side of the dam body 1 located near the gate support 5. Each hydraulic cylinder support 3 is equipped with a push-pull assembly for pushing the gate 12 to open and close. The push-pull assembly includes a second rotating seat 17, which is fixedly connected to the inclined surface at the upper end of the hydraulic cylinder support 3. A hydraulic cylinder 4 is rotatably connected inside the second rotating seat 17. A third rotating seat 17 is fixedly connected to the upper end of the gate 12. A rotating seat 2 is rotatably connected to the output end of the hydraulic cylinder 4. During operation, the hydraulic cylinder 4 acts as a power actuator. Relying on the characteristic of the rotating seat 17 and the cylinder support 3 being rotatably connected, its output end is linked to the gate 12 through the first rotating seat 2. At the same time, the fixed support rod 15 provides a flipping support for the gate 12 with the third rotating seat 16 as the fulcrum. When the hydraulic pump station 6 delivers hydraulic oil through the oil pipe 11 and the electrical system controls the oil circuit circulation, the extension and retraction of the hydraulic cylinder 4 will cause the gate 12 to flip around the hinge point between the fixed support rod 15 and the third rotating seat 16 as the center. When it is necessary to open the gate 12 to release water, the hydraulic cylinder 4 drives the gate 12 to flip to one side to allow water to flow through. When it is necessary to close the gate 12 to store water, the hydraulic cylinder 4 reverses its action to reset the gate 12 and form a water-blocking structure.
[0021] Please see Figure 1 and Figure 2 A bankside machine room 9 is constructed on one side of the dam body 1. The bankside machine room 9 is equipped with a control device for controlling the opening and closing components. The control device includes a hydraulic pump station 6 and hydraulic oil pipes 11. The hydraulic pump station 6 is located in the bankside machine room 9. The hydraulic pump station 6 is connected to the hydraulic cylinder 4 through the hydraulic oil pipes 11 to control the extension and retraction of the hydraulic cylinder 4. The bankside machine room 9 provides a stable and protective installation environment for the hydraulic pump station 6, which can effectively isolate the impact of river flow, silt erosion and adverse weather conditions such as wind and rain, avoid damage to the core components of the hydraulic pump station 6, extend the service life of the equipment, and facilitate the maintenance and repair of the control device by the staff.
[0022] The hydraulic pump station 6 can output stable hydraulic power, which is precisely transmitted to the hydraulic cylinder 4 through the hydraulic oil pipe 11, directly controlling the extension and retraction of the hydraulic cylinder 4. As the actuator, the extension and retraction of the hydraulic cylinder 4 will drive the gate 12 to rotate around the hinge point between the fixed support rod 15 and the third rotating seat 16, ultimately realizing the opening and closing of the gate 12. Please see Figure 1The shore-side machine room 9 is also equipped with a monitoring component for monitoring water level; the monitoring component includes a monitor 8, which is located on the top of the shore-side machine room 9 and is used to monitor the dam body 1 area. A level gauge 10 for detecting water level is also provided on one side of the dam body 1; an electrical control box 7 is provided inside the shore-side machine room 9, and the monitor 8, level gauge 10 and hydraulic pump station 6 are all electrically connected to the electrical control box 7; a reinforcing rib 14 is fixedly connected to the side of the gate 12 near the gate support 5; The monitor 8 provides real-time visual monitoring of the dam area 1. Staff can directly observe the opening and closing status of the gate 12 and the river flow through the monitoring screen, avoiding the risks of blind control during remote operation. It also facilitates the timely detection of gate jamming, abnormal water flow, and other malfunctions, and assists in daily inspections, allowing staff to monitor the surrounding conditions of the dam without frequent on-site visits, thus reducing management costs. The level gauge 10 on one side of the dam 1 accurately detects the river water level data in real time and transmits the data to the electrical control box 7, providing a basis for the automated opening and closing of the gate 12. When the water level reaches the flood season release threshold or the dry season storage threshold, the signal from the level gauge 10 directly triggers the automatic control program of the electrical control box 7, completing the gate action without manual intervention and achieving completely unattended water level control.
[0023] The working principle of this utility model is as follows: During operation, the hydraulic pump station 6 delivers hydraulic power to the hydraulic cylinder 4 through the hydraulic oil pipe 11, directly controlling the extension and retraction of the hydraulic cylinder 4. The oil circulation of the hydraulic pump station 6 is regulated by the electrical system. Its extension and retraction will cause the gate plate 12 to rotate around the hinge point between the fixed support rod 15 and the third rotating seat 16. When the hydraulic cylinder 4 retracts, it pulls the gate plate 12 to rotate towards the gate plate support 5 to open. When the hydraulic cylinder 4 extends, it pushes the gate plate 12 to rotate outward to reset, forming a complete water-blocking structure to close.
[0024] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Although this specification describes embodiments, not every embodiment contains only one technical solution. This method of description is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can be appropriately combined to form other embodiments that can be understood by those skilled in the art.
