Description

Technical Field

[0001] The invention belongs to the technical field of water conservancy engineering gate equipment, and in particular relates to a screw type slot gate structure. Background Art

[0002] Traditional slot gates mostly use flat gates or flap gates, which have the following problems: 1. Inflexible opening and closing: Manual operation is laborious and it is difficult to accurately control the flow.

[0003] 2. Poor sealing: The contact surface between the gate and the tank body is prone to water leakage, affecting the use effect.

[0004] 3. High maintenance cost: complex structure, easy to wear, and requires frequent maintenance. Summary of the invention

[0005] In order to make up for the deficiencies of the prior art, the present invention provides a screw type slot gate structure.

[0006] The present invention is achieved through the following technical solutions: A screw-type slot gate structure includes a base, a gate frame and a gate plate, and is characterized in that the gate frame is fixed on the base, the gate plate is hinged on the gate frame, the center of the gate plate end is hinged to the screw, the screw passes through a swing box, the swing box is hinged on a top frame, and the top frame is fixed to the top of the gate frame.

[0007] The screw rod is sleeved with a gear nut, the gear nut is meshed with a power gear, the gear nut and the power gear are installed in a reducer, and the reducer is driven by a power motor.

[0008] Sector-shaped guide rail plates are integrally installed on both sides of the gate plate.

[0009] The beneficial effects of the present invention are as follows: the screw transmission mechanism makes the gate opening and closing more stable and precise, and is suitable for a variety of working conditions; the self-locking characteristics of the screw ensure that the gate remains stable at any position without the need for additional fixing devices; the structure is simple, easy to disassemble and maintain, and reduces the long-term use cost; the gate size and drive mode can be adjusted according to actual needs, and is suitable for projects of different scales. BRIEF DESCRIPTION OF THE DRAWINGS

[0010] The present invention will be further described below in conjunction with the accompanying drawings.

[0011] Attached Figure 1 It is a structural schematic diagram of the present invention; Attached Figure 2 It is a schematic diagram of the screw transmission power of the present invention; In the figure, 1 is a base, 2 is a gate frame, 3 is a gate plate, 4 is a screw, 5 is a swing box, 6 is a top frame, 7 is a gear nut, 8 is a power gear, 9 is a speed reducer, 10 is a power motor, and 11 is a fan-shaped guide plate. DETAILED DESCRIPTION

[0012] The accompanying drawings are a specific embodiment of the present invention. This embodiment includes a base 1, a gate frame 2 and a gate plate 3. The gate frame 2 is fixed on the base 1, and the gate plate 3 is hinged on the gate frame 2. The center of the end of the gate plate 3 is hinged to the screw 4. The screw 4 passes through the swing box 5. The swing box 5 is hinged on the top frame 6. The top frame 6 is fixed to the top of the gate frame 2. A gear nut 7 is sleeved on the screw 4. The gear nut 7 is meshed with a power gear 8. The gear nut 7 and the power gear 8 are installed in a reducer 9. The reducer 9 is driven by a power motor 10. Sector guide plates 11 are integrally installed on both sides of the gate plate 3.

[0013] The screw-type slot gate structure of the present invention is adopted, and the power motor 10 is started. The power motor 10 drives the power gear 8 to rotate slowly through the reducer 9, and the power gear 8 drives the gear nut 7 to rotate, thereby driving the screw 4 to move upward, so that the gate plate 3 can be driven to rotate. The gate plate 3 is hinged on the gate frame 2, and the gate plate 3 will rotate in an arc with the hinge point as the center of the circle. At this time, the fan-shaped guide plate 11 can ensure the stability and reliability of the gate plate 3 during rotation. At the same time, the swing box 5 will also rotate around the top frame 6 at a small angle. Through the forward and reverse rotation of the power motor 10, the gate plate 3 is driven to open or close, or reach any angle, which is used to accurately control the flow of water or liquid.

[0014] The flow rate can be calculated according to the triangular weir flow rate formula by the upstream and downstream water levels and the opening of the gate plate 3. The screw 4 transmission has a self-locking function, which can ensure that the gate plate 3 remains stable at any position and avoid displacement of the gate plate 3 due to water pressure or external force.
