At present, the integrated gate may produce large hydraulic losses during operation, especially when it is fully closed, the water flow will be subject to greater resistance, and a larger opening and closing device needs to be used.

DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technical personnel in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figures 1 to 5 The utility model provides a technical solution: a foldable automatic lifting gate, including a gate pier 1, which is distributed at both ends of a gate bottom 2 and cast as one with the gate bottom 2, a hydraulic control system 3 is installed on one side of the gate pier 1, a gate assembly 4 is opened between the gate piers 1, the bottom of the gate assembly 4 is rotatably connected to the top of the gate bottom 2 through a first hinge 5, the gate assembly 4 is composed of a gate block 6 and a gate block connecting member 7, the gate block 6 and the gate block connecting member 7 are connected by bolts, the gate block connecting member 7 is fitted and connected to one side of the gate pier 1, the bottom of the gate block 6 and the gate block connecting member 7 is rotatably connected to the top of another group of gate blocks 6 and gate block connecting members 7 through a second hinge 8, the gate block connecting member 7 is rotatably connected to a hydraulic cylinder 10 through an oil cylinder fixing member 9 welded inside the gate block connecting member 7, the power output end of the hydraulic cylinder 10 is rotatably connected to a lifting arm 11, the lifting arms 11 are connected by a connecting member 12, and the connecting member 12 is rotatably connected to one end of the second hinge 8.

[0022] The hydraulic control system 3 includes a control body 301 , an oil tank 302 , a hydraulic motor 303 and an oil pipe 304 . The control body 301 is electrically connected to the hydraulic motor 303 , and the oil tank 302 is connected to the hydraulic cylinder 10 via the oil pipe 304 .

[0023] In this embodiment, Figure 1As shown, the gate assembly 4 is distributed with a gate assembly 4 consisting of a plurality of gate blocks 6 and gate block connecting members 7 of the same number in the vertical structure, and the gate assembly 4 is provided with a plurality of groups in the horizontal structure and fits each other; the modular combination between the gate blocks 6 and the gate block connecting members 7 can be combined and adjusted according to the gate chamber width of the river channel and the water level of the river channel to adapt to different water levels and water flow conditions. This structure improves the flexibility of gate use in daily life, thereby improving the operating efficiency and reliability of water conservancy projects. Different from the daily integrated gate, which needs to be replaced as a whole once damaged, the modular combination formed between the monomers is also convenient for daily maintenance, greatly saving the cost of maintenance.

[0024] In this embodiment, Figure 1 and Figure 2 As shown, the gate assemblies 4 are connected in pairs through the second hinges 8, and the second hinges 8 are staggeredly distributed at both ends of the gate assemblies 4; the distribution position of the second hinges 8 on the surface of the gate assembly 4 enables the subsequent gate assemblies 4 to share the forces generated at different positions when realizing the opening and closing structure, thereby ensuring that the gate assembly 4 is more evenly stressed when the whole is folded, reducing the damage caused by local stress, and helping to improve the overall stability of the gate assembly 4 to adapt to different water conservancy working conditions as needed.

[0025] In this embodiment, Figure 3 and Figure 4 As shown, the lifting arms 11 are in relative motion through the hydraulic cylinder 10; the lifting arms 11 are driven by the hydraulic cylinder 10 to achieve folding and contraction, and thus the folding range of the gate assemblies 4 under the opening and closing structure is larger, thereby achieving flexible control of the water flow, and the speed, direction and distribution of the water flow can be adjusted by presenting the gate assemblies 4 at different angles to meet specific engineering needs.

[0026] In this embodiment, Figure 4As shown, the gate assemblies 4 are in a structural form of two-by-two vertical distributions and form a Z-shaped folding structure between the inner walls of the gate pier 1 through the hydraulic cylinder 10 and the lifting arm 11, and the gate assemblies 4 are in a structural form of a vertical array and form a horizontal flip structure through the hydraulic cylinder 10 and the lifting arm 11 while being attached to the surface of the gate bottom 2; the Z-shaped folding and retracting manner of the gate assembly 4 can greatly reduce the space occupied by the gate in the retracted state, which is of great significance for limited places. At the same time, through the cooperation of the hydraulic cylinder 10 and the lifting arm 11, a variety of structural forms can be adjusted to adapt to a variety of scenes, and can be folded up when it is not necessary to be fully opened, which can save space and reduce the impact on the surrounding environment, and can also better adapt to different water flows. Conditions and water levels change, so that operators can make real-time adjustments according to actual conditions to ensure the normal operation of water conservancy projects and the effective use of water resources. At the same time, compared with integrated or lifting gates, its flexible and diverse adjustment methods can also be used to create various unique waterscape effects. By adjusting the entire gate assembly 4, different water flow forms and water surface landscapes can be created, increasing the diversity and beauty of the landscape, making it blend with the surrounding landscape and buildings, and when each independent monomer is damaged, it can also be replaced separately, greatly saving maintenance costs. In short, the lifting arm 11 structure plays a key role in the operation of the gate assembly 4, providing necessary support and control for the folding operation of the gate assembly 4.

[0027] In this embodiment, Figure 1 , Figure 2 and Figure 3 As shown, one side of the outer wall of the first hinge 5 and the second hinge 8 is coated with a rubber waterproof layer; since the corresponding first hinge 5 and the second hinge 8 will be in an opening and closing motion state at the same time during the folding process between the gate assembly 4, the addition of the rubber waterproof layer can effectively prevent moisture from leaking through the gap between the first hinge 5 and the second hinge 8, thereby improving the waterproof performance of the gate assembly 4. At the same time, the material on the surface of the first hinge 5 and the second hinge 8 also plays a certain buffering and shock-absorbing role, which can reduce the friction and noise when the gate assembly 4 is opened and closed, making it run more smoothly and quietly, and at the same time also prolonging the service life of the first hinge 5 and the second hinge 8.

[0028] The use method and advantages of the utility model: When the foldable automatic lifting gate is used, the working process is as follows:

[0029] like Figure 1 , Figure 2 , Figure 3 and Figure 4 and Figure 5As shown, first, the oil tank 302 delivers oil to the hydraulic cylinder 10 through the hydraulic oil pump through the oil pipe 304, and in actual use, the automatic control program can be realized through the control body 301, and various working modes and corresponding postures of the gate components 4 are simulated according to the water level and flow rate, and the sequencing or synchronous operation instructions of the gate components 4 are specified, which are compiled into the hydraulic control system 3 in the form of data or program. The display of each operation terminal provides a human-computer dialogue interface in the form of graphics or direct data input. The operator clicks or enters data on the terminal window to complete the operation, or uses manual In the manual control mode, if the folding and folding of the gate assembly 4 under the array structure needs to be completed, when the hydraulic cylinder 10 is driven, its output end pushes one side of the lifting arm 11 in a relative motion, the upper hydraulic cylinder 10 pushes the lifting arm 11 to move downward, and the lower hydraulic cylinder 10 pushes the lifting arm 11 to move upward. Since one side of the gate assembly 4 is connected by the second hinge 8, the opening and closing of one side is realized, and at the same time, the folding of the gate assemblies 4 is realized. The hydraulic control system on one side of the gate assembly 4 is started according to the structural form that needs to be folded. The system 3 drives the hydraulic cylinder 10 to realize the folding of the gate assembly 4, and when it is necessary to fully unfold it, it can be realized by reverse driving of the hydraulic cylinder 10. In addition, in order to increase the maximum use range of the gate, the gate assembly 4 connected to the surface of the gate bottom 2 through the first hinge 5 can be additionally provided with a group of hydraulic cylinders 10, so that the overall gate assembly 4 can be turned over and horizontally attached to the surface of the gate bottom 2. This structural form can provide the largest barrier-free channel for water flow, thereby maximizing the drainage volume and improving the drainage efficiency of the water conservancy project. The way in which the system 3 realizes the adjustment of the gate assembly 4 can control the speed, direction and distribution of the water flow, thereby achieving flexible control of the water flow. It can also be used to create various unique waterscape effects and increase the diversity and beauty of the landscape. In actual use, the hydraulic control system 3 can be provided with a start button and an emergency stop switch, and electrically connect the hydraulic cylinder 10 for driving the lifting arm 11 between each unit of the gate assembly 4 according to the control body 301. It is not necessary to drive the upper and lower groups of hydraulic cylinders 10 at the same time, and then the control of the gate assembly 4 is realized through its control body 301.
