Abstract
Description
Technical Field
[0001] This application relates to the field of gate mechanism technology, and in particular to a high-efficiency servo-driven upward-opening gate. Background Technology
[0002] Existing top-opening flat gates are widely used in water supply and drainage, sewage treatment, and chemical pipeline systems. They typically consist of a frame, a gate panel, and a circumferential sealing pair. Opening and closing are achieved by the linear movement of the gate panel in the vertical direction, and closing is achieved through surface or line contact between the frame sealing seat and the gate panel sealing surface. Common guiding mechanisms are often shaft-sleeve or guide rail-slider combinations to ensure the straightness of the gate panel's stroke and the fit at the end. However, traditional structures are often designed so that the gate panel maintains continuous contact with the sealing strip throughout its entire stroke, resulting in friction. This is particularly disadvantageous in media containing solid particles or suspended matter: during opening and closing, the gate panel and sealing strip are always in frictional contact. Especially in media containing solid particles or suspended matter, the sealing surface is easily scratched and eroded, and the sealing strip undergoes permanent compression deformation, leading to increased opening and closing resistance, shortened sealing life, and increased leakage rate. Utility Model Content
[0003] The purpose of this application is to provide a high-efficiency servo-driven top-opening gate that is simple in structure, easy to disassemble and assemble, and has high gate opening and closing accuracy and efficiency.
[0004] To achieve the above objectives, this utility model provides a high-efficiency servo-driven top-opening gate, including a gate frame, a gate plate slidably connected to the gate frame, and a valve actuator connected to the gate plate and capable of driving the gate plate to slide up and down along the gate frame. The gate frame is a rectangular frame structure with a gate opening at the bottom and sliding grooves on both sides of the gate frame. Rollers are provided on both sides of the gate, and the rollers are slidably connected in the groove, so that the gate can block the gate opening of the gate frame; The valve is driven by a servo electric cylinder. The cylinder body of the servo electric cylinder is rotatably connected to the top of the gate frame, and the telescopic rod of the servo electric cylinder is rotatably connected to the bottom of the gate plate. When the telescopic rod of the servo electric cylinder extends or retracts, it can drive the gate plate to slide up and down along the gate frame.
[0005] To facilitate the disassembly, assembly, and transportation of the gate frame while ensuring its overall strength, the gate frame includes two opposing side frames, as well as a top frame and a bottom frame respectively located at the top and bottom of the two side frames. The outer end faces of the side frames are provided with several reinforcing ribs.
[0006] To facilitate control of the overall size of the gate, several baffles are fixed to the front side of the side frame, and the baffles are spliced together to form a rectangular gate.
[0007] To ensure the stability of the gate during movement, two sliding grooves perpendicular to the horizontal plane are provided on the side frame. The sliding grooves include an upper sliding groove and a lower sliding groove, which are not on the same straight line.
[0008] Corresponding to the upper and lower sliding grooves, a set of roller shafts are fixed on both sides of the gate. The roller shafts include an upper roller shaft and a lower roller shaft, and rollers are rotatably connected to the roller shafts respectively. The rollers on the upper roller shaft are slidably connected in the upper sliding groove, and the rollers on the lower roller shaft are slidably connected in the lower sliding groove.
[0009] Since the gate and the baffle are in contact when the gate blocks the gate opening, the bottom of the upper slide groove and the lower slide groove have an arc-shaped part that bends to one side in order to avoid generating greater resistance when they rise and fall.
[0010] To facilitate the rotation of the servo electric cylinder, a set of mounting seats is fixed on the top frame, and the cylinder body of the servo electric cylinder is rotatably connected to the mounting seats through a first pin. Similarly, a set of mounting plates is fixed to the bottom of the gate, and the bottom of the telescopic rod of the servo electric cylinder is rotatably connected to the mounting plates through a second pin.
[0011] In summary, this utility model has the following beneficial effects: the high-efficiency servo-driven top-opening gate adopts a spliced structure, which is convenient for disassembly, assembly and transportation, and has a low manufacturing cost. Through the cooperation of the servo electric cylinder with the gate frame and the gate plate, the opening degree of the gate can be controlled efficiently and quickly, thereby accurately controlling the water flow rate. Compared with traditional gates, this utility model has the advantages of simple installation, short friction stroke, zero leakage, servo drive, high efficiency and precision.

[0015] like Figure 1 , Figure 2 The invention relates to a high-efficiency servo-driven top-opening gate, which includes a gate frame, a gate 5 slidably connected to the gate frame, and a valve drive connected to the gate 5 and capable of driving the gate 5 to slide up and down along the gate frame.
[0016] Specifically, the gate frame is a rectangular frame structure, including two oppositely arranged side frames 1, and a top frame 2 and a bottom frame 3 respectively arranged at the top and bottom of the two side frames 1. The outer end face of the side frame 1 is provided with several reinforcing ribs 18. The top frame 2, bottom frame 3 and side frame 1 are channel steel and adopt a detachable splicing structure to facilitate on-site disassembly and assembly. The reinforcing ribs 18 can ensure the strength of the entire gate frame. Four baffles 6 are fixed on the front side of the side frame 1. The baffles 6 are spliced to form a rectangular gate. Two sliding grooves perpendicular to the horizontal plane are respectively provided on the side frame 1. The sliding grooves include an upper sliding groove 7 and a lower sliding groove 8. The upper sliding groove 7 and the lower sliding groove 8 are not on the same straight line, and the bottom of the upper sliding groove 7 and the lower sliding groove 8 have an arc-shaped part 9 that bends to one side. Specifically, the gate 5 can block the gate opening and give the top of the gate frame a hollow window 17. A set of roller shafts are fixed on both sides of the gate 5. The roller shafts include an upper roller shaft 11 and a lower roller shaft 12. Rollers 10 are rotatably connected to the roller shafts. The rollers 10 on the two upper roller shafts 11 are slidably connected to the upper sliding grooves 7 of the two side frames 1. The rollers 10 on the two lower roller shafts 12 are slidably connected to the lower sliding grooves 8 of the two side frames 1. Specifically, the valve is driven by a servo electric cylinder 4. A set of mounting seats 13 is fixed on the top frame 2. The cylinder body of the servo electric cylinder 4 is rotatably connected to the two mounting seats 13 through a first pin 14. A set of mounting plates 15 is fixed at the bottom of the gate 5. The bottom of the telescopic rod of the servo electric cylinder 4 is rotatably connected to the mounting plates 15 through a second pin 16.
[0017] In use, the telescopic rod of the servo electric cylinder 4 moves upward, pulling the gate 5 upward. Each roller 10 gradually disengages from the arc-shaped part 9 of each slide, so that the gate 5 no longer adheres to each baffle 6, thereby reducing the resistance to upward movement. The telescopic rod continues to pull the gate 5 upward, and each roller 10 moves upward along each slide, gradually opening the gate. The opening degree of the gate can be precisely controlled by the servo electric cylinder 4.
[0018] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape, principle and application direction of this application should be covered within the scope of protection of this application.
