Description

Technical Field

[0001] This utility model relates to the field of weir gate technology, specifically a hydraulic rotary anti-backflow weir gate. Background Technology

[0002] A large number of sewage discharge pipes are laid underground in cities. At the junctions of these sewage pipes, there are usually combined sewer interception wells or separate sewer interception wells. Through the diversion and guiding function of these interception wells, the sewage is directed to sewage treatment plants or external waterways.

[0003] Rotary weirs are typically used before the drainage outlets of intercepting wells or discharge points. During the dry season, urban sewage is treated before being discharged into rivers, requiring sewage treatment equipment to achieve this purpose. However, during the flood season, the water level in the river rises, and river water flows into the city's underground pipe network through the discharge outlets, causing urban flooding.

[0004] To prevent flooding caused by backflow from external rivers during the flood season, a hydraulically operated adjustable weir was designed and installed at the drainage outlet. During the dry season or the initial rainfall period when the water level in the external river is low, the rotating weir gate is open, allowing treated wastewater to be discharged into the river. During the flood season when the water level in the external river is high, the weir is completely closed, sealing the drainage outlet and preventing backflow.

[0005] The utility model disclosed in announcement number CN221441723U is an integral anti-backflow hydraulic rotating weir gate, including a weir gate frame, a weir plate, a weir plate base, a hydraulic drive rod and a hydraulic drive rod base. The weir plate is hinged to the weir plate base. Two hydraulic drive rods are provided, and their telescopic ends are both hinged to the middle of the inner side of the weir plate through a weir plate connecting seat.

[0006] As shown in the above-mentioned rotating weir gate, the existing rotating weir gate has proposed a new lip-sealing structure. Compared with the traditional sealing scheme, the lip-sealing structure has a larger contact area with the weir plate and a double seal from the lip and the convex surface of the sealing strip, resulting in a better sealing effect. However, this type of rotating weir gate is driven by two externally mounted hydraulic drive rods. When driving the weir gate, the externally mounted hydraulic drive rods need to rotate through a movable structure. This connection method makes the weir gate less strong and unable to withstand the impact of large water pressure, thus affecting the sealing performance of the weir gate. Summary of the Invention

Detailed Implementation

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] like Figure 1-4 As shown, this utility model provides two technical solutions:

[0028] First embodiment: A hydraulic rotary anti-backflow weir gate 23, including a wall 1, a weir gate 23 assembly 2, a drive assembly 3, and an adjustment assembly 4.

[0029] A weir opening is provided at the lower end of the wall 1. A weir gate frame 11 is provided on the outer side of the inner opening of the weir opening. A sealing ring is adhered to the end side wall of the weir gate frame 11. The sealing ring improves the sealing performance.

[0030] The weir gate 23 assembly 2 is located at the lower end of the inner cavity of the wall 1. The weir gate 23 assembly 2 corresponds to the weir gate frame 11. The weir gate 23 assembly 2 includes multiple equally spaced mounting seats 21. The mounting seats 21 are fixed to the inner wall of the wall 1 by bolts. The middle part of the mounting seat 21 is movably connected to the connecting seat 22 by a bearing. The connecting seat 22 is fixedly connected to the weir gate 23 by bolts. The weir gate 23 corresponds to the weir gate frame 11, so that the weir gate 23 can rotate and fit into the weir gate frame 11 after rotating a certain angle.

[0031] The drive assembly 3 is located at the upper end of the inner cavity of the wall 1 and is connected to the weir gate 23 assembly 2. It is used to drive the weir gate 23 assembly 2 to rotate. The drive assembly 3 includes two symmetrically distributed first hydraulic cylinders 31. A bonding plate 32 is fixed to the output shaft of each first hydraulic cylinder 31. An L-shaped plate 33 is bonded to the lower surface of the bonding plate 32. A fixing plate 34 is located at the bottom end of the L-shaped plate 33. The fixing plate 34 is connected to the output shaft of the first hydraulic cylinder 31 via a screw. A mounting plate 35 is located between the two L-shaped plates 33. Both lower ends of the mounting plate 35 are fixed to the L-shaped plates 33 via multiple connecting posts 36. Both upper ends of the mounting plate 35 are connected to the L-shaped plates 33 via take-up rollers 37. A winding roller 37 is mounted on the mounting plate 35. Motor 38 is a bidirectional motor. Both ends of motor 38 are connected to two take-up rollers 37 via drive shafts. A connecting rope 39 is wound around the take-up rollers 37. A clamping plate 310 is fixed to the bottom of the connecting rope 39. The clamping plate 310 is clamped to one end of the weir gate 23, and the bottom of the clamping plate 310 is fixed to the weir gate 23 by bolts. Motor 38 drives the two take-up rollers 37 to take up the weir synchronously. The take-up rollers 37 drive the weir gate 23 to rotate via the connecting rope 39, so that the weir gate 23 closes the weir opening. The two first hydraulic cylinders 31 are connected to the same oil tank and can extend and retract synchronously. After the take-up rollers 37 have finished taking up the weir, the first hydraulic cylinders 31 drive the L-shaped plate 33 to retract, thereby causing the weir gate 23 to fit tightly against the weir gate frame 11.

[0032] The second embodiment differs from the first embodiment in that: the adjusting component 4 is installed at the upper end of the inner cavity of the wall 1, and is connected to the driving component 3 to adjust the height of the driving component 3. The adjusting component 4 includes a second hydraulic cylinder 41 fixed to the inner wall of the upper end of the wall 1. The output end of the second hydraulic cylinder 41 is connected to a connecting plate 42. Mounting brackets 43 are provided at the bottom of both ends of the connecting plate 42. A stud 44 is fixed at the top of one end of the mounting bracket 43. The stud 44 passes through the through holes opened at both ends of the connecting plate 42 and is fixedly connected to the connecting plate 42 by nuts. A movable plate 45 is fixed at one end of the mounting plate 35, and a swallowtail is fixed on the inner side of the movable plate 45. The upper end of the inner wall of the wall 1 has a dovetail groove 13 that is adapted to the dovetail slider 46. The dovetail slider 46 and the dovetail groove 13 work together to guide the mounting frame 43 to move vertically up and down. The other end of the mounting frame 43 is fixed to the upper end of the first oil cylinder 31 by bolts. A baffle 47 is fixed to the bottom of the other end of the mounting frame 43. The baffle 47 fits against the upper end of the first oil cylinder 31. The second oil cylinder 41 drives the mounting frame 43 to move upward through the connecting plate 42, which in turn drives the drive assembly 3 to move upward as a whole, making the connection between the weir gate 23 and the weir gate frame 11 tighter and improving the sealing performance of the device.

[0033] When this device is in operation, the motor 38 is started first. The motor 38 drives the two take-up rollers 37 to take up the winding synchronously. The take-up rollers 37 drive the weir gate 23 to rotate through the take-up connecting rope 39 until the weir gate 23 rotates to the weir gate frame 11. At this time, the two first hydraulic cylinders 31 are activated. The first hydraulic cylinders 31 drive the L-shaped plate 33 to rotate, which in turn drives the weir gate 23 to continue to rotate, so that the weir gate 23 and the weir gate frame 11 are tightly fitted. When the take-up rollers 37 become somewhat loose, the second hydraulic cylinder 41 is activated. The second hydraulic cylinder 41 drives the drive assembly 3 to move upward through the connecting plate 42, so that the weir gate 23 and the weir gate frame 11 are kept tightly fitted, which improves the sealing performance of this device.

[0034] The connecting plate 42 and the first hydraulic cylinder 31 are designed to be detachable, making it easy to disassemble and maintain the winding roller 37 and the motor 38. The connecting plate 42 is connected to the mounting frame 43 by screws and nuts, making the first hydraulic cylinder 31 detachable for maintenance, and also making it easy to disassemble and replace the mounting frame 43 after it has been deformed for a period of time.
