Description

Technical Field

[0001] This invention belongs to the field of hydropower and water conservancy engineering technology, and in particular relates to a method for avoiding operational interference between a deep-sea hydraulic press and a cylinder hinge. Background Technology

[0002] The stepless stratified water intake gate device is a product developed to protect the aquatic ecological environment. The patent document with announcement number CN114215020B discloses a highly efficient and fast stepless stratified water intake gate device, and the deep-diving hydraulic press is one of its main drive mechanism types. Based on the connection type between the deep-sea hydraulic press and the upper hinge seat downstream of the gate frame, there are two types: middle hinge and end hinge. Patent application document CN117744337A discloses a refined positioning method for the underwater drive device of a submerged gate. According to the resistance moment when the movable gate flap is open and closed, a reasonable pushing and pulling force value and working stroke are determined by the torque balance equation method, and a hydraulic cylinder hinge seat is proposed. However, it does not disclose how the deep-sea hydraulic press avoids operational interference with the upper hydraulic cylinder hinge seat downstream of the gate frame. Therefore, it is impossible to accurately determine whether the swing process of the deep-sea hydraulic press cylinder will collide with the upper hydraulic cylinder hinge seat downstream of the gate frame, causing it to fail to achieve full stroke operation. If the deep-sea hydraulic press cylinder collides with the hydraulic cylinder hinge seat, it will cause damage to the cylinder and hinge seat, resulting in economic losses, and in severe cases, it will affect power generation and ecological environmental protection.

[0003] Furthermore, the cylinder hinge seats of traditional deep-sea hydraulic presses use welded fixed supports. For centrally hinged supports, it is difficult to separate the cylinder from the hinge seat during later maintenance of the deep-sea hydraulic press. Sometimes, cutting is required, which damages the hinge seat. This increases maintenance costs and prolongs maintenance time. When the cylinder is end-hinged, the interference between the cylinder and the lifting head connecting plate of the hinge seat increases the opening size. This leads to a longer support span of the cylinder lifting shaft, which increases the bending moment it bears. This increases the diameter of the cylinder lifting shaft and the corresponding structural size of the cylinder, resulting in an increase in the cost of the deep-sea hydraulic press. Summary of the Invention

Finally, align the center of the second lower lifting head with point O9.

[0015] The beneficial effects of this invention are as follows: 1. Based on the running trajectory of the connection point of the deep-sea hydraulic press and the movable gate, the swing area of ​​the cylinder centerline during the full stroke of the deep-sea hydraulic press is determined. Then, the deep-sea hydraulic press is laid out according to the front, back, upper and lower limit positions of the swing area of ​​the cylinder centerline. This allows for the accurate determination of the swing range of the deep-sea hydraulic press's shape. The hinge structure is designed to meet the swing range requirements of the deep-sea hydraulic press's shape, thereby avoiding operational interference between the deep-sea hydraulic press and the cylinder hinge, effectively improving the operational reliability of the stepless stratified water intake gate device, and ensuring the environmental protection effect of stratified water intake.

[0016] 2. For the central hinge support of the deep-sea hydraulic press, a separate hydraulic cylinder hinge support is adopted, which is assembled with the cylinder sleeve hinge shaft on the left and right sides respectively and then fixed to the flange plate of the top crossbeam of the door frame with bolts. This facilitates installation and disassembly, improves maintenance efficiency and reduces operation and maintenance costs.

[0017] 3. For the end hinge support of the deep-sea hydraulic press, a multi-plate support type cylinder hinge is welded to the top crossbeam flange of the door frame. By adding a multi-plate support structure with an inner connecting plate of the lifting head to the inner side of the lifting head connecting plate of the hinge, the support span of the cylinder lifting shaft is reduced to a large extent while keeping the opening size of the lifting head connecting plate of the cylinder and the hinge unchanged. This effectively reduces the structural size of the cylinder and saves investment. Attached Figure Description

[0022] The method for determining the swing area of ​​the cylinder centerline during the full stroke of the centrally articulated deep-sea hydraulic press 1 includes the following steps: B1: Determine the rotation center of the movable door 2 when it is fully closed as point O1, the center of the fully closed connection between the central articulated deep-sea hydraulic press 1 and the movable door 2 as point O2, the rotation center of the upper hanging point of the central articulated deep-sea hydraulic press 1 as point O3, and the outer edge point P1 of the cylinder centerline downstream of the upper hanging point of the central articulated deep-sea hydraulic press 1.

B3: When the movable door 2 is in the fully open state, the center of the fully open connection point between the central articulated deep-sea hydraulic press 1 and the movable door 2 is point O5. Thus, the running trajectory of the connection point center during the process of the movable door 2 from fully closed to fully open is determined to be the arc O2O5. The connecting line segment O3O5 intersects with the arc O2O5 at point P2. The swing area of ​​the cylinder centerline upstream and below the rotation center point O3 of the upper hanging point of the central articulated deep-sea hydraulic press 1 is determined to be the area O3O4O5 composed of line segment O3O4, line segment O3O5 and arc O4O5, and the area O3O2P2 composed of line segment O3P2, line segment O3O2 and arc P2O2.

C2: Connect line segments O1O2 and O1O4, measure the angle α between the arc O2O4 formed by line segments O1O2 and O1O4 on circle O1, and measure the angle β between line segments O3O4 and O3O2. C3: First, rotate the movable door flap 2, which is in a fully closed state, counterclockwise to the lowest point within the included angle α with point O1 as the center. Then, rotate the middle articulated deep-sea hydraulic press 1 clockwise to the highest point within the included angle β with point O3 as the center. Finally, align the center of the lower lifting head 3 of the middle articulated deep-sea hydraulic press 1 with point O4. Determine that the intersection point B of the upper outer edge of the middle articulated deep-sea hydraulic press 1 and the split cylinder hinge seat 5, with the BB section along the vertical direction, is the anti-interference interface. C4: Measure the angle γ between the movable gate flap 2 after C3 rotation and the horizontal line; C5: Rotate the movable door flap 2 counterclockwise around point O1 within the included angle γ to a horizontal state, determine the center point O5 of the connection suspension point of the movable door flap 2 in the horizontal state, and measure the angle θ between line segment O3O4 and line segment O3O5.
