Description

Technical Field

[0001] This utility model relates to the field of water conservancy engineering technology, and more specifically, to a large-span water conservancy gate. Background Technology

[0002] In the construction of water conservancy projects, navigation control locks, as key facilities, bear the heavy responsibility of regulating water levels, ensuring navigation conditions, and managing water resources. Currently, large-span working gates of navigation control locks mainly adopt two forms: one is a flat gate + winch hoist scheme, and the other is a stacked beam gate + trolley hoist scheme. These schemes have several shortcomings in practical applications, mainly as follows:

[0003] 1. Flat gate + winch hoist solution: The flat gate is a single gate, and opening and closing the gate usually requires overall hoisting. Although the discharge flow can be initially controlled by setting the gate height, it is difficult to achieve precise dynamic flow adjustment, so the flexibility is low. Moreover, the flat gate is heavy, and opening and closing usually requires the use of a double-lifting-point winch hoist, which not only has high equipment cost, but also considerable installation and maintenance costs. At the same time, the cross-gate beam bridge under the winch requires a high clearance height, resulting in a large amount of structural engineering work for the beam bridge and support beam, which further increases the overall cost.

[0004] 2. Stacked beam gate + trolley opening and closing scheme: Theoretically, the stacked beam gate can dynamically adjust the discharge flow by installing gate sections of different numbers. However, the gate is a simply supported structure at both ends, and the bending moment is large when the span is large, resulting in a large amount of steel consumption and an increase in the weight of the gate, which brings inconvenience to installation and operation and has poor flexibility. Utility Model Content

[0005] The main objective of this invention is to provide a large-span hydraulic gate to solve the problem of insufficient flexibility in existing large-span hydraulic gates.

[0006] To achieve the above objectives, according to one aspect of the present invention, a large-span hydraulic gate is provided, comprising a gate frame, a support beam, and multiple gate inserts. The gate frame has a gate opening; both ends of the support beam are connected to the gate frame and are located at the top of the gate frame; the support beam has multiple insertion holes, and each gate insert is respectively inserted into each insertion hole, and the gate inserts are movable relative to the support beam to block or avoid at least part of the gate opening.

[0007] Furthermore, a longitudinal guide rail is provided on the side wall of the socket, and the insertion plate door is inserted into the socket along the longitudinal guide rail.

[0008] Furthermore, the socket includes a flared section and a straight section connected in sequence. The flared section is located at the top of the straight section, and the opening size of the flared section decreases from top to bottom. The insertion plate door extends into the socket through the flared section, and the straight section has a longitudinal guide rail.

[0009] Furthermore, the insertion holes are arranged horizontally and perpendicular to the water flow direction. The support beam includes a steel panel and a steel truss. The steel panel is provided with insertion holes. The steel truss and the steel panel are connected and arranged along the water flow direction.

[0010] Furthermore, a door groove is provided at the bottom of the gate frame. The length direction of the door groove is perpendicular to the water flow direction, the width direction of the door groove is parallel to the water flow direction, and the width of the door groove is greater than the thickness of the gate plate.

[0011] Furthermore, the depth of the door groove is set to 0.5-1 times the thickness of the door panel.

[0012] Furthermore, the gate slot has a first side and a second side, which are arranged alternately along the water flow direction. The surface of the first side is inclined and is inclined downward along the water flow direction.

[0013] Furthermore, the gate frame has two oppositely arranged side walls and a bottom wall for connecting the two side walls, forming a gate opening between the side walls and the bottom wall. The support beam is arranged opposite to the bottom wall, and both ends of the support beam are connected to the two side walls respectively.

[0014] Furthermore, multiple support beams are provided, and each support beam is aligned vertically.

[0015] Furthermore, the top of the slide gate is equipped with lifting lugs for connecting to lifting equipment.

[0016] By applying the technical solution of this utility model, multiple insertion holes are provided in the support beam, allowing multiple gate inserters to be installed inside the gate. This enables flexible partial or complete opening and closing of the gate, thereby improving the flexibility of large-span hydraulic gates. Specifically, this embodiment decomposes the traditional large-span hydraulic gate into a support beam and multiple vertical gate inserters. The support beam provides multiple installation positions for the gate inserters at the top of the gate frame, effectively shortening the support span of the gate inserters, reducing bending moment, and consequently reducing the weight of the gate inserters. This makes the opening and closing of the gate inserters more flexible and can be coordinated with conventional gates. Standard lifting equipment can easily raise and lower the slide gate, and can reduce the bending moment of the slide gate during opening and closing, making the overall structural stress of the large-span hydraulic gate more reasonable, thereby improving the stability and safety of the large-span hydraulic gate. On the other hand, each slide gate can be raised and lowered individually or simultaneously, which is conducive to flexible control of the discharge flow, making the adjustment of the large-span hydraulic gate to different water levels and flow requirements more flexible and controllable. At the same time, the support beam and slide gate are installed separately, and each slide gate can be manufactured and installed separately, which helps to reduce the difficulty of production and installation, and thus reduce installation and maintenance costs.

[0031] To address the lack of flexibility in existing large-span hydraulic gates, this invention provides a large-span hydraulic gate.

[0032] like Figures 1 to 8 The large-span hydraulic gate shown includes a gate frame 10, a support beam 20, and multiple gate 30s. The gate frame 10 has a gate opening. Both ends of the support beam 20 are connected to the gate frame 10 and are located at the top of the gate frame 10. The support beam 20 has multiple holes 211, and each gate 30 is respectively inserted into each hole 211. The gate 30 is adjustable in height relative to the support beam 20 to block or avoid at least part of the gate opening.

[0033] This embodiment, by providing the support beam 20 with multiple insertion holes 211, allows for the installation of multiple gate panels 30 within the gate opening, thus enabling flexible partial or complete opening and closing of the gate. This improves the flexibility of large-span hydraulic gates. Specifically, this embodiment decomposes a traditional large-span hydraulic gate into a support beam 20 and multiple vertical gate panels 30. The support beam 20 provides multiple installation positions for the gate panels 30 at the top of the gate frame 10, effectively shortening the support span of the gate panels 30, reducing bending moment, and consequently reducing the weight of the gate panels 30. This makes the opening and closing of the gate panels 30 more flexible and allows for better coordination. Conventional lifting equipment can easily raise and lower the gate 30, and can reduce the bending moment of the gate 30 during opening and closing, making the overall structural stress of the large-span hydraulic gate more reasonable, thereby improving the stability and safety of the large-span hydraulic gate. On the other hand, each gate 30 can be raised and lowered individually or simultaneously, which is conducive to flexible control of the discharge flow, making the adjustment of the large-span hydraulic gate to different water levels and flow requirements more flexible and controllable. At the same time, the support beam 20 and the gate 30 are installed separately, and each gate 30 can be manufactured and installed separately, which helps to reduce the difficulty of production and installation, and thus reduce installation and maintenance costs.

[0034] like Figure 5As shown, in this embodiment, a longitudinal guide rail is provided on the side wall of the insertion hole 211. The insertion gate 30 is inserted into the insertion hole 211 along the longitudinal guide rail, thereby ensuring the guidance and stability of the insertion gate 30 during the lifting and lowering process, preventing the insertion gate 30 from deviating when impacted by water flow in the water, and thus improving the reliability of the operation of the large-span hydraulic gate. Specifically, the inner wall of the insertion hole 211 in this embodiment is made of steel plate, and multiple steel plates form a rectangular insertion hole 211 for the insertion gate 30 to enter. The axial direction of the insertion hole 211 extends along the height direction, so the inner wall of the insertion plate can be directly used as the longitudinal guide rail. Of course, a longitudinal guide rail extending along the height direction can also be separately provided on the inner wall of the insertion hole 211 to guide the insertion gate 30. Optionally, the longitudinal guide rail can be provided only on one side wall of the insertion hole 211, or it can be provided on two opposite side walls of the insertion hole 211, as long as it can ensure the smooth lifting and lowering of the insertion gate 30.

[0035] In this embodiment, the insertion hole 211 includes a flared section 212 and a straight section 213 connected in sequence. The flared section 212 is located at the top of the straight section 213, and the opening size of the flared section 212 decreases from top to bottom. The insertion gate 30 extends into the insertion hole 211 through the flared section 212. The straight section 213 has a longitudinal guide rail, which makes it easier to align the insertion gate 30 into the insertion hole 211, even in turbulent water conditions, thus improving the operational efficiency of large-span hydraulic gates. Specifically, as... Figure 4 , Figure 5 As shown, in this embodiment, the flared section 212 is designed with a four-sided bevel, resulting in a larger opening at the top of the insertion hole 211 compared to the cross-section of the straight section 213. This provides a guiding effect for the insertion gate 30, making it easier to insert the insertion gate 30 into the straight section 213, thus reducing operational difficulty. It also reduces direct collisions between the insertion gate 30 and the straight section 213, ensuring the safety of the longitudinal guide rail and extending the service life of the large-span hydraulic gate. Preferably, the flared section 212 in this embodiment is welded from steel plates, facilitating the insertion of the insertion gate 30 into the slot. The straight section 213 is equipped with a longitudinal guide rail made of angle steel, which has high rigidity. The inner angle of the angle steel is aligned with the insertion hole 211, facilitating the downward placement of the insertion gate 30 along the guide rail.

[0036] In this embodiment, the insertion holes 211 are arranged horizontally, with the arrangement direction perpendicular to the water flow direction. The support beam 20 includes a steel panel 21 and a steel truss 22. The steel panel 21 is provided with insertion holes 211. The steel truss 22 is connected to the steel panel 21, and the steel truss 22 and the steel panel 21 are arranged along the water flow direction. In this way, the steel panel 21 provides a support point for the gate 30, and the steel truss 22 further ensures the structural strength and rigidity of the support beam 20, thereby making the entire large-span hydraulic gate more stable and easier to hoist. Specifically, as follows... Figure 4 As shown, the support beam 20, which serves as the supporting structure for the insertion gate 30, adopts a steel truss structure. Along the water flow direction, the upstream side is a steel panel 21 with insertion holes 211, and the downstream side is a steel truss 22, thereby ensuring that the support beam 20 has the characteristics of high rigidity and light weight, so as to facilitate the hoisting of lifting equipment.

[0037] In this embodiment, the steel panel 21 is configured as a cuboid structure, with its length perpendicular to the water flow direction. The steel panel 21 is welded from steel plates and includes a front panel, a rear panel, a top panel, and a bottom panel. Insertion holes 211 are provided for mounting the insertion door 30. Steel panels are arranged around each insertion hole 211, forming a single unit. Each insertion hole 211 is positioned along the length of the steel panel 21. To ensure the guiding function of the longitudinal guide rail, the steel panels at the insertion holes 211 also serve as longitudinal guide rails. The length of the steel truss 22 is also perpendicular to the water flow direction. Considering the stability of the triangular structure, triangular structures can be used at both ends of the steel truss 22's length. To maintain lightweight construction, a steel truss structure is preferred for the steel truss 22. The steel truss 22 can be welded from angle steel or round tubular steel to increase rigidity. Compared to steel plates, angle steel and round tubular steel are lighter, have more reasonable stress distribution, and are beneficial for saving steel. In this way, the steel panel 21 and the steel truss 22 can distribute the load transmitted by the gate 30, thereby improving the load-bearing capacity of the support beam 20. At the same time, the steel truss structure can reduce the self-weight of the support beam 20 while ensuring the strength of the support beam 20, thereby ensuring the structural safety of the large-span hydraulic gate and reducing the installation and maintenance costs of the large-span hydraulic gate.

[0038] In this embodiment, a gate slot 121 is provided at the bottom of the gate frame 10. The length direction of the gate slot 121 is perpendicular to the water flow direction, and the width direction of the gate slot 121 is parallel to the water flow direction. That is to say, as Figure 1 , Figure 6As shown, in this embodiment, the length direction of the gate slot 121 is parallel to the length direction of the steel panel 21, and the gate slot 121 and the insertion hole 211 are vertically aligned. This allows the bottom of the gate 30 to be inserted into the gate slot 121 when it is inserted into the insertion hole 211 and continues to descend. The width of the gate slot 121 is greater than the thickness of the gate 30, allowing the gate 30 to easily enter and exit the gate slot 121, thereby improving the operational flexibility of large-span hydraulic gates. Thus, the insertion hole 211 limits the gate 30 at its top, and the gate slot 121 limits the gate 30 at its bottom, ensuring the stability of the gate 30 in the water flow. Preferably, the width of the door groove 121 is set to 1.5-2 times the thickness of the insert door 30 to ensure that the insert door 30 can smoothly enter the groove. When the water flow rate is high, the width of the door groove 121 can be set larger to facilitate the insertion of the insert door 30 into the groove. When the water flow rate is slow, the width of the door groove 121 can be appropriately reduced to ensure the stability of the fit between the door groove 121 and the insert door 30. It should be noted that the thickness direction of the insert door 30 is in the water flow direction.

[0039] In this embodiment, the depth of the door groove 121 is set to 0.5-1 times the thickness of the insert door 30. This ensures that the insert door 30 can transmit the impact force of the water flow to the support beam 20 and the gate frame 10, thereby ensuring the stability of the insert door 30 in the water and preventing it from shaking or tilting due to the impact of the water flow, which could cause the insert door 30 to come out of the door groove 121. It also helps to ensure a seal between the insert door 30 and the door groove 121. Preferably, the depth of the door groove 121 is greater than or equal to 0.5m to ensure that the door groove 121 has sufficient depth to support the insert door 30 and prevent it from coming out.

[0040] like Figure 3 As shown, in this embodiment, the gate slot 121 has a first side 1211 and a second side 1212, which are arranged alternately along the water flow direction. The surface of the first side 1211 is inclined and tilted downwards along the water flow direction, which facilitates the insertion of the gate 30 into the slot, thereby improving the efficiency of the operation of the large-span hydraulic gate and ensuring the stability of the gate 30. Specifically, the inclined first side 1211 forms a bevel in the direction of the incoming water flow, which can guide the movement of the gate 30, making it easier for the gate 30 to smoothly insert into and exit the gate slot 121, thereby improving the opening and closing efficiency of the large-span hydraulic gate. The plane containing the second side 1212 is perpendicular to the direction of water flow and is located downstream of the water flow. By utilizing the natural guiding effect of the water flow, under the action of the water flow force, the insert door 30 presses against the second side 1212 through the contact between the insert door 30 and the door groove 121, thereby forming an effective seal and water stop, and ensuring the stability and safety of the insert door 30.

[0041] In this embodiment, the gate frame 10 has two opposing side walls 11 and a bottom wall 12 connecting the two side walls 11. The side walls 11 and the bottom wall 12 form a gate opening. The support beam 20 is opposite to the bottom wall 12, and both ends of the support beam 20 are connected to the two side walls 11 respectively, thus forming a stable support structure to ensure the reliability of the large-span hydraulic gate. Specifically, the gate frame 10 is configured as a U-shaped mechanism, with side frames on both sides and a bottom wall 12 at the bottom. A gate slot 121 is set on the bottom wall 12, and the support beam 20 is installed on the side walls 11, forming a U-shaped structure between the support beam 20 and the gate frame 10. In this way, the load of the gate 30 can be effectively transferred to the support beam 20 through the insertion hole 211 and to the gate frame 10 through the gate slot 121, thereby ensuring the stability of the entire large-span hydraulic gate.

[0042] like Figure 2 , Figure 3 As shown, in this embodiment, a support platform for supporting the support beam 20 is provided on the side wall 11. The support beam 20 is installed on the support platform, and a pad 40 is provided between the support platform and the support beam 20. The rubber pad acts as a buffer structure to reduce the impact on the gate frame 10 when the support beam 20 is placed. The rubber pad is fixed to the support platform with bolts. Optionally, the pad 40 can be a rubber pad. When multiple support beams 20 are provided along the height direction, multiple support platforms are also provided along the height direction on the side wall 11, and the support platforms are aligned vertically to ensure that the multiple support beams 20 can be aligned vertically. Preferably, in order to ensure that the support beam 20 effectively limits the insertion gate 30, the support platform can be provided in the upper or middle part of the side wall 11.

[0043] In this embodiment, multiple support beams 20 are provided, and the support beams 20 are aligned vertically to improve the bending resistance of the large-span hydraulic gate, thereby enhancing the overall strength of the large-span hydraulic gate and providing multi-point support for the gate 30, making the gate 30 more stable when subjected to water flow forces. Specifically, when the vertical span is large, multiple support beams 20 can be arranged vertically to reduce the local stress on the gate 30, such as... Figure 6 As shown, two support beams 20 are provided, aligned vertically and spaced a certain distance apart, which can distribute the load transmitted by the insert door 30, reduce local stress concentration on the insert door 30, improve the structural life of the insert door 30, and reduce failures caused by uneven structural stress.

[0044] It should be noted that both the insert door 30 and the support beam 20 in this embodiment are made of steel. This embodiment reduces the support span of the insert door 30, thereby reducing the bending moment, which helps to save steel usage and thus reduce the weight of the insert door 30.

[0045] like Figure 7 , Figure 8 As shown, the slide gate 30 in this embodiment is a structure for controlling the discharge flow rate, used to withstand water flow force and hydrostatic pressure. The slide gate 30 consists of a panel, partitions, and a beam system. The panel includes a first panel and a second panel, which are arranged along the water flow direction and opposite to each other. At least one of the first panel and the second panel cooperates with a longitudinal guide rail and moves up and down along the longitudinal guide rail. There are multiple partitions, which are located between the first panel and the second panel and connect the first panel and the second panel. The partitions are spaced apart along the height direction to improve the structural strength of the slide gate 30. There are multiple beam systems, which are inclined and located both between the first panel and the second panel and between two adjacent partitions, so that the beam system, the panel, and the partitions form multiple triangular grid structures, thereby improving the structural strength of the slide gate 30. Preferably, as shown... Figure 8 As shown, considering that the bottom of the insert door 30 is subjected to greater force, the spacing between two adjacent partitions gradually decreases from top to bottom, and the inclination angle of the beam system relative to the horizontal plane gradually decreases. This makes the partitions and beam system at the bottom of the insert door 30 denser, thus forming a structure that is sparse at the top and dense at the bottom. This results in higher structural strength at the bottom where the force is greater, ensuring the structural strength of the insert door 30 while keeping its self-weight relatively low.

[0046] like Figure 7 , Figure 8As shown in this embodiment, to facilitate hoisting, the top of the gate 30 is provided with a lifting lug 31, which is used to connect with a lifting device, thereby enabling the gate 30 to be hoisted by the lifting device. This simplifies the installation and maintenance process of the large-span hydraulic gate and improves work efficiency. Specifically, the large-span hydraulic gate in this embodiment adopts a structure of support beam 20 and multiple gates 30, and the support beam 20 adopts a steel truss structure. As a result, the self-weight of the support beam 20 and the gates 30 is relatively small, which makes the installation of the large-span hydraulic gate highly flexible. It does not require special opening and closing machinery, and the weight of the support beam 20 and the gates 30 can meet the transportation and installation requirements of a tire-mounted crane. Therefore, a tire-mounted crane can be used for transportation and installation. A ring-shaped lifting lug 31 can be installed at the top of the gate 30. The lifting lug 31 is positioned horizontally in the middle of the gate 30 to ensure balance during lifting. The gate 30 is then lifted using the vertical lifting capacity of the lifting equipment, connected to the lifting lug 31. A similar ring-shaped lifting lug 31 can also be installed at the top of the support beam 20. The lifting lugs of the support beam 20 can be positioned between two adjacent insertion holes 211. Considering the relatively long length of the support beam 20, two lifting lugs can be symmetrically installed on it to ensure safety during lifting. Of course, since the gate 30 and support beam 20 are lighter than traditional large-span hydraulic gates, a wider range of lifting methods and equipment can be used. Therefore, the structure of the lifting lug 31 and the lifting equipment employed are not limited to these and can be adjusted according to actual conditions.

[0047] In this embodiment, the support platform and gate slot 121 of the gate frame 10 provide a stable foundation for the support beam 20 and the sliding gate 30. The installation of multiple sliding gates 30 significantly reduces the bending moment value, and the installation of the support beam 20 further significantly reduces the bending moment value. When the support beam 20 and sliding gate 30 are not installed, the water flows out through the gate opening of the gate frame 10. When the support beam 20 and sliding gate 30 are installed, the water flows out through the gap between adjacent sliding gates 30. When it is necessary to adjust the water level or navigation conditions, the operator can use a tire crane to lift the vertical sliding gate 30 through the lifting lug 31 and insert or pull it into the insertion hole 211 of the support beam 20 along the longitudinal guide rail. Under the action of the water flow force, the gate body automatically presses against the second side 1212 of the gate slot 121 to form a waterstop line, ensuring the watertightness of the large-span hydraulic gate. The operation of the large-span hydraulic gate does not require special opening and closing machinery, which greatly reduces the maintenance workload and cost. The design of multiple gate valves (30mm) allows the large-span hydraulic gate to flexibly adjust the discharge flow according to actual needs, improving the flexibility and efficiency of water resource management. During operation, the entire large-span hydraulic gate not only ensures safe and smooth navigation but also enables effective regulation of water resources.

[0048] It should be noted that "multiple" in the above embodiments refers to at least two.

[0049] As can be seen from the above description, the embodiments of this utility model achieve the following technical effects:

[0050] 1. It solves the problem of insufficient flexibility of large-span hydraulic gates in existing technologies;

[0051] 2. By setting the support beam with multiple insertion holes, multiple gate plates can be installed inside the gate, thereby flexibly realizing the partial or complete opening and closing of the gate, thus improving the flexibility of large-span hydraulic gates.

[0052] 3. By decomposing the traditional large-span hydraulic gate into a support beam and multiple vertical gate plates, the support beam can provide multiple installation positions for the gate plates at the top of the gate frame. This effectively shortens the support span of the gate plates, reduces the bending moment, and further reduces the self-weight of the gate plates, making the opening and closing of the gate plates more flexible.
