Description

Technical Field

[0001] The invention relates to the technical field of water conservancy projects, and in particular to a triangular gate structure. Background Art

[0002] The triangular gate is a gate composed of two triangular or fan-shaped gates that rotate around a vertical axis to open and close. It has the advantages of two-way water retaining and dynamic water opening and closing. It is widely used in gates at large estuaries.

[0003] The traditional triangular gate includes gate side piers, a rotating shaft, a fixed arm, a fixed support, a gate body and a supporting side pier. The fixed arm drives the gate body to rotate around the rotating shaft to control the opening and closing of the gate. The fixed arm is connected to the fixed support to jointly support the gate body. During the opening and closing process of the gate, the gate side piers provide support to ensure smooth opening and closing of the gate. With the support of the supporting side piers, the entire sluice is in a stable and safe state.

[0004] However, when the triangular gate is used in large estuaries, the gate body is large in size, and when encountering emergencies such as rapid changes in tide levels during flood season, the gate opening and closing time is long. In other words, the triangular gate has poor emergency response capabilities when facing emergencies such as tide blocking, flood prevention, and waterlogging drainage. Summary of the invention

[0005] In view of this, the present invention provides a triangular gate structure to solve the problem that the existing triangular gate has poor emergency response capability when facing emergencies such as tide blocking, flood prevention, and waterlogging drainage.

[0006] Specifically, the present invention provides a triangular gate structure, including a gate chamber and a gate structure. The gate chamber is installed at the estuary, and the gate chamber is provided with a water outlet; the gate structure is provided with two, and any of the gate structures includes a first gate body, a driving member, and a second gate body. The first gate body can be movably installed at the water outlet of the gate chamber, and the first gate body is provided with an active chamber. The end face of the first gate body close to the other gate structure is provided with an opening connected to the active chamber, and the driving member is used to move in the active chamber toward or away from the opening. One end of the second gate body is located in the active chamber and is fixedly connected to the driving member, and the other end of the second gate body is provided with a driving member. The end extends toward the opening of the active chamber where it is located, and the second gate door body near the water outlet midline in any of the gate structures is used to approach or move away from the second gate door body near the water outlet midline in another gate structure driven by a driving member; wherein, when the second gate door bodies near the water outlet midline in the two gate structures are abutted against each other, the two gate structures are used to close the water outlet and block the water from flowing out of the water outlet of the gate chamber, and when the second gate door bodies near the water outlet midline in the two gate structures are spaced apart, the gate structure is used to open the water outlet of the gate chamber to facilitate the outflow of water.

[0007] Beneficial effects: By designing two gate structures, each gate structure includes a movable first gate body and a second gate body driven by a driving member. Compared with the existing solution that only uses one gate body, the structure of the present application can make the gate operation more flexible and convenient when dealing with emergencies, and reduce the project footprint, shorten the construction period, and reduce the project investment. Specifically, since the driving member can quickly drive the second gate body to move, the second gate body close to the water outlet midline in the two gate structures can quickly move toward the water outlet midline and abut against each other. Compared with the traditional triangular gate, the gate opening and closing time can be shortened, thereby quickly opening or closing the outlet, which helps to improve the triangular gate's emergency response capability to deal with tides or floods that require rapid closure or opening of the gate, and facilitates the improvement of the moisture-proof, flood discharge and drainage capabilities of the basin where the gate is located, ensuring the safety of the city upstream of the gate. At the same time, during the process of opening and closing the gate, since the second gate body can be completely hidden inside the first gate body, the structural size of the gate library can be reduced, thereby reducing the project footprint, shortening the construction period and reducing the project investment, so as to realize its economic and social benefits in advance.

[0008] In an optional embodiment, any of the gate structures includes at least one of the first gate bodies, and the number of the driving members, the number of the second gate bodies, and the number of the first gate bodies are arranged in a one-to-one correspondence.

[0009] Beneficial effects: First, by providing at least one first gate body and making the number of driving parts and second gate bodies equal to the first gate body, the applicable scope of the triangular gate structure can be improved, and it is convenient to select the corresponding scheme according to different working conditions. At the same time, since each first gate body is equipped with an independent driving part and a second gate body, the opening and closing time of the gate can be further shortened, so that the outlet can be opened or closed more quickly, which helps to further improve the emergency response capability of the triangular gate to deal with tides or floods that require rapid closure or opening of the gate. In addition, with such a setting, in tasks such as flood control, tide blocking and waterlogging drainage, by controlling the opening and closing degree of different gates, precise control of the water flow can be achieved, thereby better meeting the scheduling needs.

[0010] In an optional embodiment, when the number of the first gate bodies in any of the gate structures is greater than or equal to two, the other end of the second gate body away from the midline of the water outlet is connected to the adjacent first gate body close to the midline of the water outlet.

[0011] Beneficial effect: By connecting the other end of the second gate body far from the midline of the water outlet with the first gate body adjacent to the midline of the water outlet, the connection between the adjacent first gate body and the second gate body is achieved, so that their relative positions are relatively fixed, which is convenient for checking the status of each component during maintenance and inspection, and timely performing necessary repairs or replacements. At the same time, it is convenient to quickly drive the adjacent first gate body to move toward or away from the midline of the water outlet, further shortening the opening and closing time of the gate, and helping to further improve the emergency response capability of the triangular gate to deal with tides or floods that require rapid closure or opening of the gate.

[0012] In an optional embodiment, a supporting side pier is provided upstream of the water outlet of the gate chamber; the triangular gate structure also includes a rotating shaft and a main support arm, and the rotating shaft is rotatably installed around its central axis at the supporting side pier; one end of the main support arm is connected to the rotating shaft, and the other end of the main support arm is connected to the first gate body.

[0013] Beneficial effect: By rotatably installing the rotating shaft at the supporting side pier, connecting one end of the main arm to the rotating shaft, and connecting the other end of the main arm to the first gate body, the first gate body can be rotated around the rotating shaft, so that the rotating shaft and the main arm can be firmly installed and withstand the force and torque of the first gate body during the opening and closing process, thereby enhancing the stability and reliability of the triangular gate structure during the opening and closing process, and ensuring that the triangular gate structure can maintain its integrity and functionality when dealing with emergencies such as tide blocking, flood prevention, and drainage.

[0014] In an optional embodiment, there are two main supporting arms, and two adjacent main supporting arms are connected by a telescopic member.

[0015] Beneficial effects: Since each main arm corresponds to a first gate body, and the two adjacent main arms are connected by a telescopic part, it is ensured that the two first gate bodies have the same moving state during the opening and closing process, so that each first gate body can move in a coordinated and consistent manner. At the same time, the setting of the telescopic part can make the connection between the two adjacent main arms more flexible and reliable. During maintenance and overhaul, the length of the telescopic part can be adjusted to easily approach each component and carry out necessary inspection and repair work. This design not only improves maintenance efficiency, but also reduces the risk of failure caused by improper maintenance.

[0016] In an optional embodiment, the lock chamber includes a gate side pier, and the gate side pier includes a first body and a second body, the first body is provided with two and is spaced apart to form a water outlet, and a first distance H2 between the end of the first body away from the water outlet midline and the water outlet midline is greater than a second distance H1 between the end of the supporting side pier away from the water outlet midline and the water outlet midline; one end of the second body is connected to the end of the first body away from the water outlet midline, and the other end of the second body is connected to the supporting side pier.

[0017] Beneficial effect: By making the first distance H2 between the end of the first body of the gate side pier away from the water outlet midline and the water outlet midline greater than the second distance H1 between the end of the supporting side pier away from the water outlet midline and the water outlet midline, the first body and the second body form an L-shaped bending structure, which helps the gate structure to open or close smoothly around the rotating shaft.

[0018] In an optional embodiment, the first body is an arc-shaped structure, and the second body is a linear structure.

[0019] Beneficial effects: By setting the first body as an arc-shaped structure, it is convenient to guide the water body to discharge smoothly, reduce the turbulence and eddy phenomenon of the water body when passing through the outlet, help reduce the impact force of the water flow on the gate chamber, and reduce the energy loss of the water body when passing through the outlet, while improving the water flow rate, ensuring that floods or tides can be discharged smoothly, and reducing the risk of waterlogging and waterlogging. At the same time, the first body of the arc-shaped structure is more stable in mechanics, can better resist the scouring and squeezing of the water flow, improve the overall strength of the gate chamber, so that the gate chamber can withstand greater water pressure and impact force during flood discharge and flood prevention, and ensure the safety and stability of the gate chamber. In addition, the linear second body can guide and control the water flow to the outlet, ensuring that the gate chamber plays the best role in the process of flood discharge and flood prevention.

[0020] In an optional embodiment, the lock chamber further includes a guide slide rail, which is installed at the lock chamber, one end of the slide groove of the guide slide rail is located at the second body, and the other end of the slide groove of the guide slide rail extends to the water outlet midline, and the guide slide rail is used to guide the first gate body and the second gate body to move between the second body and the water outlet midline.

[0021] Beneficial effects: By providing a guide rail, a clear moving path is provided for the first gate body and the second gate body, ensuring the stability and accuracy of the gate during opening and closing. Since the guide rail's slide groove is located between the second body and the midline of the water outlet, it can ensure that the first gate body and the second gate body move between the second body and the midline of the water outlet. At the same time, the design of the guide rail helps to reduce direct friction and collision during the movement of the gate, reduces the risk of failure caused by deviation or shaking of each gate body, and improves the reliability and safety of the movement of each gate body.

[0022] In an optional embodiment, two guide rails are provided, and the two guide rails are symmetrically arranged with the midline of the water outlet as the symmetry axis.

[0023] Beneficial effect: By providing two guide rails symmetrically arranged with the midline of the water outlet as the symmetry axis, the two gate structures are facilitated to move along the same path, reducing the problem of asynchronous opening and closing caused by offset or shaking of the gate bodies of the two gate structures.

[0024] In an optional embodiment, the slide groove of the guide slide rail is an arc-shaped slide groove, and the first gate door body and the second gate door body are arc-shaped door bodies.

[0025] Beneficial effects: By setting the slide groove of the guide slide rail as an arc-shaped slide groove, and setting the first gate door body and the second gate door body as an arc-shaped door body, the impact force of the water flow on the gate can be better dispersed. At the same time, the guidance of the arc-shaped slide groove also reduces the risk of deformation or damage of the gate due to uneven force, and improves the overall strength of the gate structure. In addition, it can also enable the gate to move along a smoother path during the opening and closing process, reducing the friction and resistance of the gate during the movement, and improving the efficiency and smoothness of the gate opening and closing.

[0036] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0037] In the description of the present application, it should be understood that the terms "center", "upper", "lower", "inside", "outside", etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present application.

[0038] The terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of this application, unless otherwise specified, "plurality" means two or more.

[0039] In the description of this application, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0040] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0041] The triangular gate, as a triangular or fan-shaped door structure consisting of two doors that can be rotated around a vertical axis to open and close, has been widely used in water conservancy facilities in large estuaries due to its ability to block water in both directions and to open and close flexibly in dynamic water flows.

[0042] The traditional triangular gate includes several key components, such as the gate side pier, rotating shaft, fixed arm, fixed support, gate body and supporting side pier. Among them, the fixed arm plays a vital role, which connects and drives the gate body to rotate around the rotating shaft, thereby accurately controlling the opening and closing of the gate.

[0043] At the same time, the fixed arm and the fixed support work together to provide solid support for the gate body. During the gate opening and closing process, the gate side pier plays an indispensable supporting role, ensuring the smooth and stable movement of the gate. The addition of the supporting side pier further enhances the stability and safety of the entire sluice structure.

[0044] However, when triangular gates are used in large estuaries, the size of the gate body also increases, which undoubtedly poses a higher challenge to the efficiency of the gate opening and closing. Especially at critical moments such as flood season, sudden changes in tide levels often occur. In other words, when faced with emergency tasks such as tide blocking, flood control, and waterlogging drainage, traditional triangular gates are difficult to quickly and effectively respond to various complex and changing hydrological conditions.

[0045] To this end, in the present application, compared with the traditional triangular gate, a valve structure with a partially hidden door body is used, and a driving member is added to drive the hidden door body to move synchronously. At the same time, the fixed support is set to a retractable form to shorten the opening and closing time of the valve, thereby solving the problem of poor emergency response capabilities of existing triangular gates when facing emergencies such as tide control, flood prevention, and drainage.

[0046] Figure 1 A schematic top view of the triangular gate structure 2 of the present application when the gate is open is shown; Figure 2A schematic top view of the triangular gate structure 2 of the present application when the gate is closed is shown.

[0047] Combine the following Figure 1 and Figure 2 , describing an embodiment of the present invention.

[0048] The present invention provides a triangular gate structure 2, comprising a gate chamber 1 and a gate structure 2. The gate chamber 1 is installed at the estuary, and the gate chamber 1 is provided with a water outlet 11; two gate structures 2 are provided, and the two gate structures 2 are set as double-door structures to achieve synchronous opening and closing.

[0049] In the present application, any gate structure 2 includes a first gate body 21 , a driving member 22 and a second gate body 23 .

[0050] Specifically, the first gate body 21 is movably installed at the water outlet 11 of the gate chamber 1 , and is provided with a movable chamber 211 . The end surface of the first gate body 21 close to the other gate structure 2 is provided with an opening communicating with the movable chamber 211 .

[0051] The driving member 22 is used to move in the active chamber 211 toward a direction close to or away from the opening.

[0052] One end of the second gate body 23 is located in the movable chamber 211 and is fixedly connected to the driving member 22, and the other end of the second gate body 23 extends toward the opening of the movable chamber 211. The second gate body 23 near the water outlet midline 12 in any gate structure 2 is used to approach or move away from the second gate body 23 near the water outlet midline 12 in another gate structure 2 under the drive of the driving member 22.

[0053] With such an arrangement, when the second gate bodies 23 of the two gate structures 2 close to the water outlet midline 12 are in contact with each other, the two gate structures 2 are used to close the water outlet 11 and block the water from flowing out of the water outlet 11 of the gate chamber 1; and when the second gate bodies 23 of the two gate structures 2 close to the water outlet midline 12 are spaced apart, the gate structures 2 are used to open the water outlet 11 of the gate chamber 1 to facilitate the outflow of water.

[0054] By utilizing the triangular gate structure 2 of this embodiment, two gate structures 2 are designed so that each gate structure 2 includes a movable first gate body 21 and a second gate body 23 driven by a driving member 22. Compared with the existing solution that only uses one gate body, the structure of the present application can make the operation of the gate more flexible and convenient when dealing with emergencies, and reduce the floor area of ​​the gate chamber 1, thereby reducing the floor area of ​​the gate project, shortening the construction period and reducing the project investment.

[0055] Specifically, since the driving member 22 can quickly drive the second gate body 23 to move, the second gate body 23 close to the water outlet midline 12 in the two gate structures 2 can quickly move toward the side of the water outlet midline 12 and abut against each other. Compared with the traditional triangular gate, the opening and closing time of the gate can be shortened, thereby quickly opening or closing the water outlet 11, which helps to improve the emergency response capability of the triangular gate to cope with tides or floods that require rapid closure or opening of the gate, and facilitates improving the moisture-proof, flood-discharging and drainage capabilities of the basin where the gate is located, thereby ensuring the safety of the city upstream of the gate.

[0056] At the same time, during the process of opening and closing the gate, since the second gate body 23 can be completely hidden inside the first gate body 21, the structural size of the gate library can be reduced, thereby reducing the project footprint, shortening the construction period and reducing the project investment, so as to realize its economic and social benefits in advance.

[0057] It can be explained that, in the present application, a winch-type door opening and closing machine is used to drive the first gate body 21 to rotate around the rotating shaft 4. Since this solution is common knowledge, it will not be described in detail here.

[0058] It can be explained that there is no specific limitation on the type of the driving member 22. It is sufficient that the driving member 22 has the ability to be electrically connected to the control terminal and has a driving end.

[0059] For example, the driving member 22 is selected to be a transmission structure with a motor sliding guide rail. For example, a sliding guide rail is provided on the side wall of the active chamber 211, and a slider is fixedly installed on the end of the second gate body 23 away from the water outlet midline 12. The slider is slidably installed in the sliding guide rail, and a telescopic structure is added, such as an electric hydraulic cylinder, so that its piston rod is fixed to the slider. The motor receives the adjustment signal sent by the control terminal and controls the piston rod to self-lock in the desired position, thereby driving the second gate body 23 to move relative to the first gate body 21 in the direction close to or away from the water outlet midline 12.

[0060] Likewise, in the present application, there is no specific limitation on the number of first gate bodies 21 in each gate structure 2, and the number may be one, two or more.

[0061] At this time, the number of the driving members 22 , the number of the second gate bodies 23 and the number of the first gate bodies 21 are arranged in one-to-one correspondence.

[0062] Therefore, by providing at least one first gate body 21 and making the number of driving members 22 and second gate bodies 23 equal to the first gate body 21, the application range of the triangular gate structure 2 can be improved, and different solutions can be selected according to different working conditions.

[0063] At the same time, since each first gate body 21 is equipped with an independent driving member 22 and a second gate body 23, the opening and closing time of the gate can be further shortened, thereby further quickly opening or closing the water outlet 11, which helps to further improve the emergency response capability of the triangular gate to cope with tides or floods that require rapid closure or opening of the gate.

[0064] In addition, with such a setting, in tasks such as flood prevention, tide blocking and drainage, by controlling the opening and closing degree of different gates, precise control of water flow can be achieved, thereby better meeting scheduling needs.

[0065] like Figure 1 and Figure 2 As shown, when the number of the first gate bodies 21 in any gate structure 2 is greater than or equal to two, the other end of the second gate body 23 away from the outlet midline 12 is connected to the adjacent first gate body 21 close to the outlet midline 12 .

[0066] Therefore, by connecting the other end of the second gate body 23 far away from the water outlet midline 12 with the adjacent first gate body 21 close to the water outlet midline 12, the connection between the adjacent first gate body 21 and the second gate body 23 is achieved, so that their relative positions are relatively fixed, which is convenient for checking the status of each component during maintenance and inspection, and carrying out necessary repairs or replacements in time.

[0067] At the same time, it is convenient to quickly drive the adjacent first gate body 21 to move toward or away from the water outlet midline 12, further shortening the opening and closing time of the gate, and helping to further improve the emergency response capability of the triangular gate to cope with tides or floods that require rapid closing or opening of the gate.

[0068] like Figure 1 and Figure 2 As shown, a supporting side pier 3 is provided upstream of the water outlet 11 of the gate chamber 1; the triangular gate structure 2 also includes a rotating shaft 4 and a main support arm 5, and the rotating shaft 4 is rotatably installed around its central axis at the supporting side pier 3; one end of the main support arm 5 is connected to the rotating shaft 4, and the other end of the main support arm 5 is connected to the first gate body 21.

[0069] By utilizing the triangular gate structure 2 of the present embodiment, by rotatably installing the rotating shaft 4 at the supporting side pier 3, connecting one end of the main arm 5 to the rotating shaft 4, and connecting the other end of the main arm 5 to the first gate body 21, the first gate body 21 can be rotated around the rotating shaft 4, so that the rotating shaft 4 and the main arm 5 can be stably installed and withstand the force and torque of the first gate body 21 during the opening and closing process, thereby enhancing the stability and reliability of the triangular gate structure 2 during the opening and closing process, and ensuring that the triangular gate structure 2 can maintain its integrity and functionality when dealing with emergencies such as tide blocking, flood prevention, and drainage.

[0070] It can be explained that the upstream of the water outlet 11 of the lock chamber 1 is defined as the upstream side of the water flow.

[0071] It should be noted that, in the above embodiment, each main arm 5 is connected to a first gate body 21 , and when the number of the main arms 5 is two, two adjacent main arms 5 are connected via a telescopic member 6 .

[0072] In this arrangement, since each main arm 5 corresponds to a first gate body 21, and the telescopic member 6 is used to connect two adjacent main arms 5, it is ensured that the two first gate bodies 21 have the same moving state during the opening and closing process, so that each first gate body 21 can move in a coordinated manner.

[0073] At the same time, the provision of the telescopic member 6 can make the connection between two adjacent main arms 5 more flexible and reliable. During maintenance and overhaul, the length of the telescopic member 6 can be adjusted to conveniently access each component and perform necessary inspections and repairs. This design not only improves maintenance efficiency, but also reduces the risk of failures caused by improper maintenance.

[0074] Among the two adjacent main supporting arms 5 , the rotation speed of the main supporting arm 5 close to the water outlet midline 12 is faster than the rotation speed of the main supporting arm 5 far from the water outlet midline 12 .

[0075] like Figure 1 and Figure 2 As shown, the lock chamber 1 includes a gate side pier 13, and the gate side pier 13 includes a first body 131 and a second body 132. The first body 131 is provided with two and is spaced apart to form a water outlet 11, and a first spacing H2 between the end of the first body 131 away from the water outlet midline 12 and the water outlet midline 12 is greater than a second spacing H1 between the end of the supporting side pier 3 away from the water outlet midline 12 and the water outlet midline 12; one end of the second body 132 is connected to the end of the first body 131 away from the water outlet midline 12, and the other end of the second body 132 is connected to the supporting side pier 3.

[0076] By utilizing the triangular gate structure 2 of the present embodiment, by making the first distance H2 between the end of the first body 131 of the gate side pier 13 away from the water outlet midline 12 and the water outlet midline 12 greater than the second distance H1 between the end of the supporting side pier 3 away from the water outlet midline 12 and the water outlet midline 12, a single first body 131 and a single second body 132 form an L-shaped bending structure, which helps the gate structure 2 to open or close smoothly around the rotating shaft 4.

[0077] At this time, the two L-shaped gate storage side piers 13 are symmetrically arranged with the midline 12 of the water outlet as the symmetry axis.

[0078] It can be explained that, in this embodiment, the shapes of the first body 131 and the second body 132 are not specifically limited, and they can be the same shape, such as a straight line, or different shapes.

[0079] As one of the implementation modes, the first body 131 is an arc-shaped structure, and the second body 132 is a linear structure.

[0080] Therefore, by setting the first body 131 as an arc-shaped structure, it is convenient to smoothly guide the water to be discharged, reduce the turbulence and eddy phenomenon of the water when passing through the outlet 11, help to reduce the impact force of the water flow on the gate chamber 1, and reduce the energy loss of the water when passing through the outlet 11, while improving the water flow rate, ensuring that floods or tides can be discharged smoothly, and reducing the risk of waterlogging and waterlogging.

[0081] At the same time, the arc-shaped first body 131 is more stable mechanically, and can better resist the scouring and squeezing of water flow, thereby improving the overall strength of the lock chamber 1, so that the lock chamber 1 can withstand greater water pressure and impact force during flood discharge and flood prevention, thereby ensuring the safety and stability of the lock chamber 1. In addition, the linear second body 132 can guide and control the flow of water to the water outlet 11, ensuring that the lock chamber 1 plays the best role in the process of flood discharge and flood prevention.

[0082] like Figure 1 and Figure 2 As shown, the lock chamber 1 also includes a guide rail 14, which is installed at the lock chamber 1, one end of the slide groove 141 of the guide rail 14 is located at the second body 132, and the other end of the slide groove 141 of the guide rail 14 extends to the water outlet midline 12, and the guide rail 14 is used to guide the first gate body 21 and the second gate body 23 to move between the second body 132 and the water outlet midline 12.

[0083] Therefore, by providing the guide rail 14, a clear moving path is provided for the first gate body 21 and the second gate body 23, ensuring the stability and accuracy of the gate during opening and closing. Since the slide groove 141 of the guide rail 14 is located between the second body 132 and the water outlet midline 12, it can ensure that the first gate body 21 and the second gate body 23 move between the second body 132 and the water outlet midline 12.

[0084] At the same time, the design of the guide rail 14 helps to reduce direct friction and collision during the movement of the gate, reduces the risk of failure caused by deviation or shaking of each gate body, and improves the reliability and safety of the movement of each gate body.

[0085] It can be explained that, in the present application, two guide rails 14 are provided, and the two guide rails 14 are symmetrically arranged with the water outlet midline 12 as the symmetry axis.

[0086] By utilizing the triangular gate structure 2 of this embodiment, two guide rails 14 are symmetrically arranged with the water outlet midline 12 as the symmetry axis, so that the two gate structures 2 can move along the same path, thereby reducing the problem of asynchronous opening and closing of the gate bodies of the two gate structures 2 due to offset or shaking.

[0087] It can be explained that the shape of the slide groove 141 of the guide slide rail 14 is not specifically limited, and is determined according to the movement mode of the first gate body 21 and the second gate body 23 .

[0088] As one of the implementation modes, the slide groove 141 of the guide slide rail 14 is an arc-shaped slide groove 141 , and the first gate body 21 and the second gate body 23 are arc-shaped gate bodies.

[0089] In this way, by setting the slide groove 141 of the guide slide rail 14 as an arc-shaped slide groove 141 and setting the first gate body 21 and the second gate body 23 as an arc-shaped gate body, the impact force of the water flow on the gate can be better dispersed.

[0090] At the same time, the guidance of the arc-shaped slide groove 141 also reduces the risk of deformation or damage of the gate due to uneven force, thereby improving the overall strength of the gate structure 2.

[0091] In addition, the gate can move along a smoother path during opening and closing, reducing the friction and resistance of the gate during movement and improving the efficiency and smoothness of the gate opening and closing.

[0092] It should be noted that, in the above embodiment, since the second gate body 23 can be hidden inside the first gate body 21, in order to meet the strength requirements of the structure, the thickness of the first gate body 21 is twice the design thickness of the traditional triangular gate, so that when the second gate body 23 is completely exposed from the first gate body 21, the structural strength of the first gate body 21 meets the use requirements.

[0093] Furthermore, let the length of the active chamber 211 ( Figure 1 and Figure 2 The arc length dimension occupied by the active chamber 211 shown in the figure is smaller than the length of the first gate body 21 ( Figure 1 and Figure 2 The second gate body 23 is completely hidden inside the first gate body 21 (as shown in the figure).

[0094] Preferably, the length of the movable chamber 211 occupies 5 / 6 of the length of the first gate body 21. Such an arrangement facilitates the upstream side and the downstream side of the first gate body 21 to be connected as a whole.

[0095] Furthermore, the thickness of the active chamber 211 may be slightly greater than the thickness of the second gate body 23, so that the second gate body 23 can move smoothly in the active chamber 211. At the same time, a sealing structure, such as a sealing ring, needs to be provided at the gap to achieve sealing.

[0096] The triangular gate structure 2 provided above, in the process of opening and closing the gate, in addition to using a winch-type hoist to drive the gate body to rotate around the rotating shaft 4 like a traditional triangular gate, and providing support through the gate side pier 13 to make the gate open and close smoothly, the triangular gate structure of this structure can drive the second gate body 23 to be exposed or hidden relative to the first gate body 21 through the driving member 22, thereby reducing the opening and closing time of the gate. The telescopic member 6 is used in combination, and the telescopic member 6 extends or contracts as the main arm 5 close to the water outlet midline 12 moves relative to the main arm 5 away from the water outlet midline 12.

[0097] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention.
