Description

Technical Field

[0001] The present application relates to the technical field of water conservancy and water transport engineering, and in particular to a hydraulic structure and a gate system thereof. Background Art

[0002] At present, in order to reduce the deadweight and reduce the difficulty of opening and closing, the tide gate usually adopts the arc gate. When the arc gate is in use, the opening and closing device drives the gate leaf to rotate through the support arm on the backwater side. When the gate leaf is impacted by the water flow on the frontwater side, most of the impact force will be transmitted to the support arm through the gate leaf, which is easy to damage the support arm and make the gate unstable as a whole. Summary of the invention

[0003] The application discloses a hydraulic structure and a gate system thereof to prevent the gate from becoming unstable.

[0004] In order to solve the above problems, this application adopts the following technical solutions:

[0005] In a first aspect, the present application provides a gate system for a hydraulic structure, the gate system comprising a gate leaf, a support arm assembly, a gate pier and an opening and closing device, the gate pier having a water passage, the gate leaf being movably arranged in the water passage; in the width direction of the gate leaf, the gate leaf is curved from the middle to the edge in an arc shape, and the curvature direction is toward the backwater side of the gate leaf;

[0006] The support arm assembly is arranged on the backwater side of the gate leaf, and the two ends of the support arm assembly are respectively connected to the gate leaf and the opening and closing device, and the opening and closing device drives the gate leaf through the support arm assembly to switch between a first state and a second state; wherein, in the first state, the gate leaf blocks the water passage, and in the second state, the gate leaf avoids the water passage.

[0007] In a second aspect, the present application provides a hydraulic structure, including the gate system provided in the first aspect of the present application.

[0008] The technical solution adopted in this application can achieve the following beneficial effects:

[0009] In the gate system of the present application, the opening and closing device can drive the gate leaf to switch between the first state and the second state through the support arm assembly. In the first state, the gate leaf blocks the water passage to block the water body on its water-facing side; in the second state, the gate leaf avoids the water passage to discharge water. In this way, the normal operation of the gate system can be achieved.

[0010] Since the gate leaf is curved in an arc shape from the middle to the edge in the width direction of the gate leaf, and the curvature direction is toward the backwater side of the gate leaf, in this case, when the gate leaf is subjected to a positive water head on the frontwater side, the edge of the gate leaf will be compressed and abut against the gate pier, thereby transmitting the water head pressure to the gate pier, thereby preventing excessive water head pressure from being directly transmitted to the support arm assembly; at the same time, the arc-shaped curved gate leaf can divert the water body, and the water body is diverted to the edge of the gate leaf in the width direction along the curved surface of the gate leaf, thereby further transmitting the water head pressure to the gate pier, thereby preventing excessive water head pressure from being directly transmitted to the support arm assembly.

[0011] Based on the above content, compared with the existing related technologies, the gate system of the present application can undoubtedly prevent excessive head pressure from being transmitted to the arm assembly, thereby protecting the arm assembly and preventing the gate system from becoming unstable.

[0024] In order to make the purpose, technical solution and advantages of the present application clearer, the technical solution of the present application will be clearly and completely described below in combination with the specific embodiments of the present application and the corresponding drawings. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present application.

[0025] The technical solutions disclosed in various embodiments of the present application are described in detail below in conjunction with the accompanying drawings.

[0026] Please refer to Figure 1 to Figure 4 The present application embodiment discloses a gate system for hydraulic structures. The present embodiment does not limit the specific type of hydraulic structures to which the gate system is applied. It can be mainly applied to tide-blocking structures. In this case, the gate system is a tide-blocking gate system. Of course, it can also be applied to water discharge structures, water intake structures, water delivery structures, etc.

[0027] The gate system of this embodiment includes a gate leaf 100 , an arm assembly 200 , a gate pier 300 and an opening and closing device 400 .

[0028] The gate leaf 100 is the main component of the gate system, which plays the role of blocking water, thereby achieving functions such as tide blocking and water storage. Specifically, the gate pier 300 has a water passage 310, based on which functions such as water discharge and navigation can be achieved. The gate leaf 100 is movably arranged in the water passage 310, that is, the gate leaf 100 can move relatively in the water passage 310 to change the setting state of the gate leaf 100.

[0029] In this embodiment, the specific shape of the door leaf 100 is not limited. Generally, the door leaf 100 can be selected as a square structural member. It should be noted that the square shape in this embodiment refers to the shape of the door leaf 100 from the perspective of the water flow direction; in this configuration, the edge shape of the door leaf 100 is relatively straight and regular, which makes it easier for the door leaf 100 to match with the embedded parts, the gate pier 300, etc. in the edge area; of course, the door leaf 100 can also be selected as a structural member of other shapes such as an ellipse.

[0030] The arm assembly 200 is a supporting component of the gate system, which is disposed on the backwater side of the gate leaf 100 and connected to the gate leaf 100 , and is used to support the gate leaf 100 to withstand the water head pressure from the frontwater side.

[0031] The opening and closing device 400 is a power component of the gate system, which can provide driving force for changing the setting state of the door leaf 100. Specifically, the two ends of the support arm assembly 200 are respectively connected to the door leaf 100 and the opening and closing device 400. The opening and closing device 400 drives the door leaf 100 through the support arm assembly 200 and can switch between the first state and the second state. The opening and closing device 400 can drive the support arm assembly 200, and the support arm assembly 200 indirectly drives the door leaf 100, and allows the door leaf 100 to switch smoothly between the first state and the second state.

[0032] Meanwhile, in the first state, the gate leaf 100 blocks the water passage 310, and in the second state, the gate leaf 100 avoids the water passage 310. It should be understood that when the hydraulic structure needs to implement functions such as water storage and tide blocking, the gate leaf 100 can be switched to the first state, at which time the gate leaf 100 can block the water body, and the water body is difficult to flow through the gate system; when the hydraulic structure needs to implement functions such as water discharge and navigation, the gate leaf 100 can be switched to the second state, at which time the gate leaf 100 avoids the water passage 310, and the water body can flow smoothly through the water passage 310.

[0033] In this embodiment, in the width direction of the gate leaf 100, the gate leaf 100 is curved from the middle to the edge in an arc shape, and the bending direction is toward the backwater side of the gate leaf 100. It should be understood that in a typical gate system, the arm assembly 200 usually bears the head pressure transmitted by all the gate leaves 100. At this time, if the gate system is opened, the arm assembly 200 is very likely to be broken under the combined action of the resistance torque and deadweight, resulting in instability of the gate system. In response to this technical problem, the gate leaf 100 of the present embodiment is curved in an arc shape from the middle to the edge in the width direction, and the bending direction is toward the back water side of the gate leaf 100. With such a configuration, when the gate leaf 100 is subjected to a positive water head, the edges on both sides in the width direction are curved in an arc shape, which is undoubtedly closer to the gate pier 300 than a typical flat gate, and will abut against the gate pier 300 when subjected to force. Therefore, part of the water head pressure can be directly transmitted to the gate pier 300, while reducing the water head pressure transmitted from the gate leaf 100 to the support arm assembly 200, which can ultimately reduce the risk probability of the support arm assembly 200 being broken when the gate system is opened.

[0034] At the same time, based on the structural feature of the gate leaf 100 being curved in an arc shape in its width direction, when the gate leaf 100 is subjected to a positive water head, the curved surface of the gate leaf 100 on the water-facing side will guide the water body and guide the water body to flow toward the edge of the gate leaf 100, thereby further allowing most of the head pressure to be transmitted to the gate pier 300 through the edge of the gate leaf 100, thereby reducing the head pressure on the arm assembly 200.

[0035] It should be noted that a typical gate system is difficult to withstand huge head pressure, so the traditional tide gate system will be subject to certain size restrictions, and it is difficult to achieve a large-span gate design in terms of width, especially in the design of gates at strong tidal estuaries. The gate system based on the embodiment of the present application can significantly reduce the head pressure borne by the arm assembly 200 on the backwater side of the gate leaf 100, and transfer most of the head pressure on the frontwater side to the gate pier 300, so it can meet the design requirements of a large-span gate (gate leaf 100) of more than 30m.

[0036] As can be seen from the above description, in the gate system of the embodiment of the present application, the opening and closing device 400 can drive the gate leaf 100 to switch between the first state and the second state through the support arm assembly 200. In the first state, the gate leaf 100 blocks the water passage 310 to block the water body on its water-facing side; in the second state, the gate leaf 100 avoids the water passage 310 to discharge water. In this way, the normal operation of the gate system can be achieved.

[0037] Since the gate leaf 100 is curved in an arc shape from the middle to the edge in the width direction of the gate leaf 100, and the bending direction is toward the backwater side of the gate leaf 100, in this case, when the gate leaf 100 is subjected to a positive water head on the frontwater side, the edge of the gate leaf 100 will be compressed and abut against the gate pier 300, thereby transmitting the water head pressure to the gate pier 300, thereby preventing excessive water head pressure from being directly transmitted to the support arm assembly 200; at the same time, the arc-shaped curved gate leaf 100 can divert the water body, and the water body is diverted to the edge of the gate leaf 100 in the width direction along the curved surface of the gate leaf 100, thereby further transmitting the water head pressure to the gate pier 300, thereby preventing excessive water head pressure from being directly transmitted to the support arm assembly 200.

[0038] In this embodiment, the gate leaf 100 can move in a variety of ways. For example, the gate leaf 100 can move up and down in the height direction of the entire gate system; or, the gate leaf 100 can move horizontally left and right in the width direction of the entire gate system. The gate pier 300 can have a accommodating chamber in the area corresponding to the gate leaf 100, and the gate leaf 100 can be accommodated in the accommodating chamber and switched to the second state.

[0039] like Figure 2As shown, in another specific embodiment, the door leaf 100 of this embodiment is rotatably arranged in the water passage 310, that is, the door leaf 100 can rotate relative to the gate in the water passage 310, and the rotation axis is parallel to the width direction of the door leaf 100, so that the door leaf 100 will not interfere with the gate and can smoothly realize the rotation action, and the two side edges of the door leaf 100 in the width direction are slidably matched with the gate pier 300, so that the friction resistance between the edge of the door leaf 100 and the gate pier 300 can be reduced, which can not only reduce the difficulty of opening the door, but also reduce the resistance torque of the support arm assembly 200.

[0040] At the same time, the opening and closing device 400 drives the arm assembly 200 to rotate. Usually, the opening and closing device 400 is connected to the arm assembly 200 through a support hinge, and the gate leaf 100 rotates with the arm assembly 200. In the height direction of the gate leaf 100, the gate leaf 100 is curved from the middle to the edge in an arc shape, and the bending direction is toward the backwater side of the gate leaf 100. Under such a setting, in the height direction of the gate leaf 100, it is equivalent to the arc gate structure type. Since the arm assembly 200 supports the gate leaf 100 on the backwater side of the gate leaf 100, the arm assembly 200 can be conveniently set in the radial direction of the gate leaf 100. When the gate leaf 100 is subjected to a positive water head, the water head pressure passes through the centroid of the gate leaf 100, thereby reducing the resistance torque of the gate leaf 100 when switching from the first state to the second state (i.e., realizing the gate opening action process of the gate system) as much as possible, so as to reduce the difficulty of opening the gate.

[0041] It should be noted that, in this embodiment, combined with the aforementioned arc-shaped bending setting feature of the door leaf 100 in the width direction, the door leaf 100 extends in an arc surface in both the width direction and the height direction. At this time, the door leaf 100 is a hyperbolic arc surface structural component; of course, the door leaf 100 can also be arc-shaped in more directions and dimensions. In the most extreme case, the door leaf 100 can be a spherical arc surface structural component.

[0042] In this embodiment, the specific sliding assembly mode of the edge of the door leaf 100 in the width direction and the gate pier 300 is not limited. For example, in a typical solution, a slide groove may be provided on the gate pier 300, and a slider may be provided on the edge of the door leaf 100 in the width direction. The slider of the door leaf 100 is embedded in the slide groove of the gate pier 300, and the slider can slide and cooperate in the slide groove. However, in the above typical solution, since the door leaf 100 of this embodiment is curved in an arc shape in both the width direction and the height direction, the curved structure of the edge of the door leaf 100 may easily interfere in the slide groove, which increases the difficulty of processing and even makes it difficult for the door leaf 100 to switch between the first state and the second state.

[0043] Based on this, Figure 3 and Figure 4As shown, the gate leaf 100 of this embodiment may be provided with sliding members 110 on its two side edges in the width direction, and the gate pier 300 is provided with a supporting surface 320, which is inclined relative to the water flow direction and opposite to the sliding member 110. The sliding member 110 may be in contact with the supporting surface 320 and slide in cooperation.

[0044] Specifically, compared with the existing chute structure, the abutment surface 320 is an open structure, which releases the constraint on the edge of the gate leaf 100, thus avoiding the interference problem of the edge of the gate leaf 100 in the chute. Since the two side edges of the gate leaf 100 in the width direction are curved, the edge of the gate leaf 100 will have a certain slope relative to the gate pier 300, that is, the two side end faces of the gate leaf 100 in the width direction are inclined relative to the water flow direction, and the abutment surface 320 of this embodiment is also set to be inclined relative to the water flow direction and opposite to the sliding member 110. In this case, when the gate leaf 100 is subjected to a positive water head, the two side edges of the gate leaf 100 in the width direction will move toward the abutment surface 320 and can smoothly abut against the abutment surface 320. At this time, the gate leaf 100 can transfer the water head pressure to the gate pier 300.

[0045] At the same time, in the height direction of the gate pier 300, the abutting surface 320 is extended in an arc shape to match the rotation trajectory of the gate leaf 100. It should be understood that the gate leaf 100 of this embodiment switches between the first state and the second state by rotating, and the gate leaf 100 is bent in an arc shape in its height direction, so the rotation trajectory of the gate leaf 100 is also in an arc shape; and the abutting surface 320 of this embodiment is also extended in an arc shape in the height direction of the gate pier 300, so when the gate leaf 100 rotates, the abutting surface 320 will always abut against the two side edges of the gate leaf 100 in its width direction, and the gate leaf 100 can always transmit the head pressure it bears to the gate pier 300.

[0046] Generally, the gate pier 300 is provided with a bottom sill 330, which is connected to the bottom of the abutting surface 320. When the gate leaf 100 is in the first state, the bottom sill 330 can support the gate leaf 100. It should be noted that the present embodiment does not limit the specific curvature of the gate leaf 100 and the abutting surface 320 and the specific rotation curvature of the gate leaf 100, as long as the gate leaf 100 does not interfere with the abutting surface 320 when rotating.

[0047] In order to prevent water from flowing away from the gap between the gate leaf 100 and the gate pier 300, the gate leaf 100 of this embodiment is usually sealed with the gate pier 300 by means of a water-stop material part 500. There are many specific types of the water-stop material part 500, such as metal sheets, plastic sheets, plastic rods, sticky and non-sticky materials, filter materials, etc. Optionally, the water-stop material part 500 of this embodiment can be selected as a rubber belt.

[0048] Since the edge of the door leaf 100 in the width direction of the present embodiment is slidably matched with the abutting surface 320 through the sliding member 110, and in order to ensure the sealing matching relationship between the sliding member 110 and the abutting surface 320, the door leaf 100 is provided with a mounting plate on the edge end surface in the width direction, and the sliding member 110 is fixedly mounted on the middle part of the mounting plate, and the two sides of the mounting plate can be sealed and matched with the abutting surface 320 through the water-stop material 500. Under such a setting, the sliding member 110 and the water-stop material 500 are integrated into a module through the mounting plate, which can undoubtedly improve the assembly and disassembly efficiency of the sliding member 110 and the water-stop material 500 on the door leaf 100. Of course, the present embodiment does not limit the specific assembly method of the sliding member 110 and the water-stop material 500 on the mounting plate, and the specific assembly method of the mounting plate on the door leaf 100. For example, they can be assembled by threaded connection, clamping, bonding, etc.

[0049] In the presence of water-stop material 500, the sliding member 110 can be preset to be spaced apart from the abutment surface 320 when the door leaf 100 is subjected to a static water head. In this way, since the door leaf 100 will be subjected to a greater head pressure when subjected to a dynamic water head, the gap between the sliding member 110 and the abutment surface 320 can be used as a movement margin for the edge of the door leaf 100, thereby preventing the sliding member 110 from moving excessively and being damaged when it abuts against the abutment surface 320.

[0050] Generally, the sliding member 110 can be directly selected as a sliding block, which has a low processing cost and can save costs. Of course, this embodiment does not limit the specific type of the sliding member 110, and it can also be selected as a roller assembly, a ball assembly, and other structures.

[0051] Due to the different sizes of the door leaf 100 or different driving requirements, the present embodiment does not limit the specific composition of the arm assembly 200 and the opening and closing device 400. For example, the arm assembly 200 is only a single arm structure, the opening and closing device 400 is a driving motor 411, and the two ends of the arm assembly 200 are respectively connected to the center of the opening and closing device 400 and the door leaf 100. The opening and closing device 400 drives the arm assembly 200 to rotate and drives the door leaf 100 to rotate.

[0052] In another specific embodiment, Figure 1As shown, the support arm assembly 200 of the present embodiment may include a first support arm subgroup 210 and a second support arm subgroup 220. In the width direction of the gate leaf 100, the first support arm subgroup 210 and the second support arm subgroup 220 are symmetrically distributed along the central axis of the gate leaf 100. The opening and closing device 400 includes a first driving mechanism 410 and a second driving mechanism 420. The first driving mechanism 410 and the second driving mechanism 420 are respectively arranged on the gate pier 300 on both sides of the water passage 310. The two ends of the first support arm subgroup 210 are respectively connected to the gate leaf 100 and the first driving mechanism 410, and the two ends of the second support arm subgroup 220 are respectively connected to the gate leaf 100 and the second driving mechanism 420.

[0053] It should be understood that the first arm subgroup 210 and the second arm subgroup 220 can share the head pressure and resistance torque transmitted from the gate leaf 100, thereby avoiding excessive load on a single arm, which also reduces the difficulty of the first drive mechanism 410 driving the first arm subgroup 210 and the second drive mechanism 420 driving the second arm subgroup 220; at the same time, in the width direction of the gate leaf 100, the first arm subgroup 210 and the second arm subgroup 220 are symmetrically arranged along the central axis of the gate leaf 100, and the head pressure and resistance torque they bear are roughly evenly distributed, thereby ensuring the uniformity of force inside the gate system and avoiding structural damage inside the gate system due to uneven force.

[0054] Furthermore, if Figure 2 As shown, the first arm subgroup 210 and the second arm subgroup 220 of the present embodiment may both include a first arm 211 and a second arm 212, one end of the first arm 211 and the second arm 212 are both connected to the door leaf 100 and are arranged at intervals, the other ends of the first arm 211 and the second arm 212 are connected and form a transmission part 213, the first drive mechanism 410 is connected to the first arm subgroup 210 via the transmission part 213, and the second drive mechanism 420 is connected to the second arm subgroup 220 via the transmission part 213.

[0055] It should be understood that, under such a configuration, the two first arms 211 and the two second arms 212 are equivalent to forming four support points on the concave surface of the door leaf 100, which can further share the head pressure and resistance torque transmitted by the door leaf 100; based on the transmission part 213, the first drive mechanism 410 and the second drive mechanism 420 can both realize simultaneous driving of the first arm 211 and the second arm 212, thereby reducing the number of drive mechanisms to save costs.

[0056] At the same time, in the height direction of the gate leaf 100, the first arm 211 and the second arm 212 are symmetrically distributed along the central axis of the gate leaf 100, and the transmission part 213 is located on the central axis of the gate leaf 100. Specifically, under such a setting, in the height direction of the gate leaf 100, the head pressure and resistance torque borne by the first arm 211 and the second arm 212 are roughly evenly distributed, which can further ensure the uniformity of force inside the gate system and avoid structural damage due to uneven force inside the gate system.

[0057] In the above-mentioned embodiment, the first support arm 211 and the second support arm 212 can be arranged in the radial direction of the gate leaf 100. At this time, the transmission part 213 is also located at the centroid of the gate leaf 100. When the gate leaf 100 transmits the head pressure to the first support arm 211 and the second support arm 212, since the first support arm 211 and the second support arm 212 have better compression and tensile properties, the ability of the support arm assembly 200 to resist the risk of instability can undoubtedly be improved, thereby achieving the effect of preventing the gate system from becoming instable.

[0058] As mentioned above, this embodiment does not limit the specific composition of the first drive mechanism 410 and the second drive mechanism 420. In a specific implementation, the first drive mechanism 410 and the second drive mechanism 420 of this embodiment may both include a drive motor 411, a gear transmission assembly and a counterweight 412. The drive motor 411 is connected to the transmission part 213 through the gear transmission assembly. The counterweight 412 is connected to the output shaft of the drive motor 411 and is located in the circumference of the output shaft of the drive motor 411. It is used to provide a positive driving action for the output shaft of the drive motor 411 when the door is opened.

[0059] In a specific working process, the driving motor 411 can drive the gear transmission assembly, and the gear transmission assembly drives the transmission part 213 to rotate. The first arm sub-assembly 210 and the second arm sub-assembly 220 can rotate with the transmission part 213 and drive the door leaf 100 to switch between the first state and the second state. Since the gear transmission assembly has the advantages of high transmission accuracy and good stability, the working stability inside the gate system can be improved. Generally, the gear transmission assembly can include a first gear arranged on the output shaft of the driving motor 411, and a gear ring or a second gear arranged on the transmission part 213. The first gear is meshed with the gear ring or the second gear to smoothly realize transmission.

[0060] It should be understood that when the gate system of the present embodiment performs the door opening operation, the drive motor 411 provides driving action by driving the transmission part 213, and needs to overcome the resistance torque transmitted by the support arm assembly 200. The counterweight 412 of the present embodiment can exert a certain driving action on the output shaft of the drive motor 411 based on its own weight, and offset part of the resistance torque transmitted by the support arm assembly 200, thereby reducing the output torque of the drive motor 411 and ensuring that the drive motor 411 can work normally even if a smaller power type is selected, which not only reduces power consumption but also saves costs.

[0061] In the aforementioned embodiment, the door leaf 100 is curved in an arc shape in multiple directions, that is, the door leaf 100 has a certain curvature in multiple directions. In this case, the curvature of the door leaf 100 may decrease after long-term use due to the impact of the head pressure, that is, the door leaf 100 will restore the deformation and reduce the pre-arch, thereby reducing the ability of the door leaf 100 to resist the risk of instability.

[0062] Based on this, the backwater side of the door leaf 100 of this embodiment may be provided with a first prestressed tensioning assembly 120 and a second prestressed tensioning assembly 130, the two ends of the first prestressed tensioning assembly 120 are connected to the two side edges of the door leaf 100 in the height direction, and the two ends of the second prestressed tensioning assembly 130 are connected to the two side edges of the door leaf 100 in the width direction. Specifically, the first prestressed tensioning assembly 120 may pre-apply tension in the height direction of the door leaf 100, and the second prestressed tensioning assembly 130 may pre-apply tension in the width direction of the door leaf 100. Even if the door leaf 100 has a tendency to recover its deformation after long-term use, the tension applied by the first prestressed tensioning assembly 120 and the second prestressed tensioning assembly 130 will offset the internal stress of the door leaf 100 recovering its deformation, thereby allowing the door leaf 100 to maintain a pre-arched degree.

[0063] In order to improve the overall rigidity of the first prestressed tensioning assembly 120 and the second prestressed tensioning assembly 130, a first truss 140 may be provided on the backwater side of the door leaf 100 of the present embodiment, and the door leaf 100 is connected to the first prestressed tensioning assembly 120 and the second prestressed tensioning assembly 130 through the first truss 140. It should be understood that based on the first truss 140, the connection relationship between the door leaf 100 and the first prestressed tensioning assembly 120 and the second prestressed tensioning assembly 130 can be strengthened, so that the integrity of the door leaf 100, the first prestressed tensioning assembly 120 and the second prestressed tensioning assembly 130 can be further optimized, which can undoubtedly improve the overall rigidity of the first prestressed tensioning assembly 120 and the second prestressed tensioning assembly 130, and prevent the first prestressed tensioning assembly 120 and the second prestressed tensioning assembly 130 from being damaged after long-term use.

[0064] Of course, the first truss 140 may also connect the first prestressed tensioning assembly 120 and the second prestressed tensioning assembly 130 to further improve the overall rigidity of the first prestressed tensioning assembly 120 and the second prestressed tensioning assembly 130 .

[0065] The present embodiment does not limit the specific types of the first prestressed tensioning component 120 and the second prestressed tensioning component 130 , which may be prestressed steel bars, prestressed anchor rods, etc.

[0066] In the aforementioned embodiment where the first arm subgroup 210 and the second arm subgroup 220 include the first arm 211 and the second arm 212, a second truss 214 may be provided between the first arm 211 and the second arm 212. The second truss 214 may optimize the integrity of the first arm 211 and the second arm 212, thereby improving the overall stiffness of the first arm subgroup 210 and the second arm subgroup 220, and thereby improving the ability of the arm assembly 200 to resist the risk of instability.

[0067] Based on the aforementioned gate system, the embodiment of the present application further discloses a hydraulic structure, which includes the aforementioned gate system. The hydraulic structure of this embodiment can be selected as a tide-blocking structure, a water discharge structure, a water intake structure, a water delivery structure, etc., and can specifically be a dam, a dike, a pond, a spillway, a water discharge or water delivery tunnel, etc.

[0068] The above embodiments of the present application focus on describing the differences between the various embodiments. As long as the different optimization features between the various embodiments are not contradictory, they can be combined to form a better embodiment. Considering the simplicity of the text, they will not be repeated here.

[0069] The above is only an embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various changes and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application should be included in the scope of the claims of the present application.
