Description

Technical Field

[0001] This utility model relates to the field of water conservancy engineering technology, specifically a new type of gate. Background Technology

[0002] In water conservancy projects, sluice gates are key equipment used to control water flow and regulate water levels, and are widely used in various scenarios such as river flood control, farmland irrigation, and urban water supply and drainage. Currently, most mainstream water conservancy sluice gates on the market adopt a vertical lifting structure, whose drive mechanism is usually quite large, requiring a large installation space. Moreover, they are prone to jamming when dealing with floating objects or bottom silt, and their opening and closing are not flexible. Utility Model Content

[0003] To address the technical problems existing in the background art, this utility model provides a novel gate.

[0004] The technical solution of this utility model is as follows: A novel gate includes a flow-limiting plate and a gate plate arranged vertically and parallel to each other, and a drive mechanism for driving the gate plate to move laterally. The flow-limiting plate is provided with a flow port. The drive mechanism includes a fixed frame that is fixedly installed on the back side of the flow-limiting plate. A gate is set between the flow-limiting plate and the fixed frame to block or open the flow port. A vertically arranged drive shaft is rotatably connected to the fixed frame. The drive shaft is equipped with a gear, and a horizontally extending rack is provided on the back side of the gate. The rack meshes with the gear. The drive shaft can drive the gate to move horizontally through the meshing of the gear and rack.

[0005] In the above scheme, the upper and lower edges of the flow limiting plate are bent towards the backwater side to form mounting plates, and the fixing frame is fixedly installed on the upper and lower mounting plates, thereby enhancing the rigidity and stability of the flow limiting plate and the overall structure of the gate.

[0006] Furthermore, guide rails are provided on the inner sidewalls of both mounting plates, and the upper and lower edges of the gate are slidably embedded in the corresponding guide rails. The guide rails provide precise guidance for the movement of the gate, ensuring smooth operation and effectively preventing the gate from shifting or jamming during movement.

[0007] In the above scheme, the rack has a U-shaped cross-section, including two sides fixedly connected to the gate and a slot bottom plate away from the gate. Multiple strip-shaped through holes are spaced apart along the length of the slot bottom plate. The gear teeth pass through the strip-shaped through holes and mesh with the side edges of the through holes to transmit power. This "hole-type" meshing method can withstand greater loads and impacts, provides more reliable transmission, and is less prone to accumulating debris.

[0008] Furthermore, the rack is fixed at the vertical center of the backwater side of the gate so that the point of application of the driving force is located in the center of the gate, which is conducive to the balanced force on the gate and smoother movement.

[0009] In the above design, the lower edge of the gate is provided with outwardly extending horizontal wedge-shaped angles at both ends. These wedge-shaped angles can guide and break up the silt when the gate closes and cuts into the bottom silt, reducing the closing resistance.

[0010] Furthermore, the lower part of both sides of the gate's transverse edge is provided with concave cutting grooves, and the wedge-shaped angles are naturally formed by the cutting grooves at both ends of the lower edge of the gate. The cutting grooves are arc-shaped notches, which not only help to cut and remove the silt on both sides when the gate moves, but the wedge-shaped angle structure they form also further reduces the opening and closing resistance, and reduces material usage and saves costs without affecting the strength of the gate.

[0011] To improve the automation of the gate, a control box is installed on the top of the fixed frame, and the control box contains a drive device for driving the drive shaft to rotate.

[0012] Furthermore, the control box is equipped with a photovoltaic panel on top, a control unit inside, at least one positioning sensor on the mounting plate, and at least two positioning receivers that cooperate with the positioning sensor on the gate. The control unit is electrically connected to the photovoltaic panel, the drive device, the positioning sensor and the positioning receivers, thereby realizing the automatic control of the opening and closing of the gate.

[0013] As a backup measure, a manual operating section is provided on the upper part of the drive shaft, and the outer circumference of the manual operating section is a hexagonal prism structure. In the event of a power outage or maintenance, the drive shaft can be manually operated using tools such as a wrench to ensure that the gate can still be opened and closed in an emergency.

[0014] The novel gate provided by this utility model, through its design of lateral gate movement, effectively overcomes the spatial height requirements of traditional vertical opening and closing methods. It facilitates installation even in situations with limited vertical space, while eliminating the need for a tall support frame, significantly reducing construction difficulty and costs. Furthermore, during lateral gate movement, the gate only needs to overcome the sliding friction between the guide rails, unlike a lifting gate which bears the entire weight of the gate. Therefore, it requires less power from the drive unit, contributing to the miniaturization and energy efficiency of the drive system. In addition, compared to traditional vertically moving gates, the laterally moving gate of this application can cut through accumulated silt from the side. Combined with the wedge-shaped angle at its bottom and the arc-shaped cutting grooves on both sides, it further enhances the silt-breaking and dredging capabilities, effectively preventing blockage problems caused by silt accumulation.

[0017] like Figure 1 and Figure 2 As shown, this utility model embodiment provides a novel gate, including a flow-limiting plate 11, a gate plate 21, and a driving mechanism.

[0018] The flow restrictor 11 is vertically fixed in the water flow channel or at the pipe port, and has an outlet 12 on it. The edge of the outlet 12 is provided with a sealing ring. The upper and lower edges of the flow restrictor 11 are bent towards the back water side to form an integral mounting plate 13. A guide rail 14 is installed on the inner sidewalls of the upper and lower mounting plates 13.

[0019] The two mounting plates 13 are combined with the flow limiting plate 11 to form a U-shaped profile structure, which enhances the rigidity and stability of the flow limiting plate 11 and the overall gate structure.

[0020] The gate 21 is located on the back side of the flow limiting plate 11 and is parallel to the flow limiting plate 11. Its upper and lower edges are respectively embedded in the upper and lower guide rails 14, and it can slide smoothly horizontally under the constraint of the guide rails 14, thereby blocking or opening the flow outlet 12.

[0021] The drive mechanism is used to drive the gate 21 to move horizontally. It includes a fixed frame 31 fixedly installed on the back side of the flow limiting plate 11. Specifically, the fixed frame 31 is fixedly installed on the upper and lower mounting plates 13. The gate 21 is located between the flow limiting plate 11 and the fixed frame 31.

[0022] A vertically arranged drive shaft 32 is rotatably connected to the fixed frame 31 via bearings and other components. A gear 33 is fixedly mounted on the drive shaft 32. On the backwater side of the gate 21, a horizontally extending rack 34 is fixedly mounted for meshing with the gear 33 to form a transmission pair. Through the transmission of the gear 33 and the rack 34, the drive shaft 32 drives the gate 21 to move horizontally, thereby blocking or opening the flow port 12.

[0023] In this embodiment, the rack 34 is preferably a "hole rack," meaning it has a U-shaped cross-section, including two sides fixedly connected to the gate 21 and a slot bottom plate away from the gate 21. Multiple strip-shaped through holes are spaced apart along the length of the slot bottom plate. When the gear 33 rotates, its teeth pass through these strip-shaped through holes and mesh with the side edges of the through holes, forming a reliable transmission pair. This "hole-type" meshing method can withstand greater loads and impacts, provides more reliable transmission, and is less prone to accumulating debris.

[0024] In order to ensure smooth movement of the gate 21, the rack 34 is preferably installed at the vertical center of the backwater side of the gate 21, so that the driving force is applied at the center of the gate 21, ensuring that the driving force is applied evenly on the gate 21.

[0025] The gate 21 of this application is configured to move horizontally to block or open the flow port 12. During its movement, it cuts into the side of the siltation. Compared with the traditional vertically moving gate, its contact surface with the siltation is smaller, making it easier to cut into the siltation, reducing the probability of the gate 21 getting stuck, and improving the reliability of the gate.

[0026] To enhance its anti-siltation capability, the two ends of the lower edge of the gate 21 are provided with outwardly extending horizontal wedge-shaped angles 22. When the gate 21 moves, the wedge-shaped angles 22 can insert into the bottom of the silt, lift the silt, and play a role in breaking up the silt, thereby reducing the resistance when the gate 21 cuts through the silt.

[0027] Furthermore, a concave cutting groove 23 is provided on the lower part of each of the two lateral edges of the gate plate 21. These two cutting grooves 23 naturally form outwardly extending wedge-shaped angles 22 at both ends of the lower edge of the gate plate 21, and can also reduce material usage and save costs without affecting the strength of the gate plate 21.

[0028] In this embodiment, the two cutting grooves 23 are horizontally symmetrically arranged, and they are arc-shaped concave notches, as detailed in the following example. Figure 1 As shown, the arc-shaped cutting groove 23 generates an oblique shear force on the silt, which can more effectively cut off and remove the silt on both sides, greatly reducing the resistance to movement.

[0029] In addition, preferably, the lowest position of the overflow port 12 corresponds to the lower half of the arc of the silt cutting groove 23 and is higher than the wedge angle 22, so as to enable better silt cutting.

[0030] Furthermore, a control box 41 is installed on top of the mounting bracket 31. The control box 41 contains a drive unit 42 and a control unit 44. The drive unit 42, which can be a servo motor, drives the drive shaft 32 to rotate. A photovoltaic panel 43 is installed on top of the control box 41 to collect solar energy and power the gate system. To achieve automated control, a positioning sensor 51 is installed on the mounting plate 13, and a corresponding positioning receiver 52 is installed on the gate 21. The control unit 44 is electrically connected to the photovoltaic panel 43, the drive unit 42, the positioning sensor 51, and the positioning receiver 52. Based on the position signal received by the positioning sensor 51, it controls the start and stop of the drive unit 42, thereby precisely controlling the opening position of the gate 21.

[0031] At least one positioning sensor 51 may be provided, and at least two corresponding positioning receivers 52 may be provided. Alternatively, the configuration can be reversed, with at least two positioning sensors 51 and at least one positioning receiver 52. This application does not limit this, as long as the positioning sensor 51 and positioning receiver 52 are present and engaged both when the gate 21 blocks the flow port 12 and when it is not blocked. Furthermore, depending on actual needs, such as the requirement for half-open or 1 / 4-open operation, the number of positioning sensors 51 and / or positioning receivers 52 can be increased.

[0032] In addition, a manual operation part 61 is provided on the upper part of the drive shaft 32, and its outer peripheral surface is machined into a hexagonal prism structure. In the event of a power outage or when on-site debugging is required, the operator can use a wrench or other tools to rotate the manual operation part 61, thereby manually driving the gate 21 to open and close, ensuring the emergency function of the equipment.

[0033] For ease of machining and assembly, the drive shaft 32 is divided into upper and lower sections, which are connected by splines and spline grooves and rotate synchronously. The upper end of the upper section is connected to the drive device 42, and the lower end is machined with a manual operation part 61. The gear is located on the lower section of the drive shaft 32.

[0034] For ease of operation, the manual operation unit 61 is positioned higher than the flow restrictor 11.
