Description

Technical Field

[0001] The utility model relates to the technical field of water conservancy, and particularly relates to a hydraulic rotary weir gate. Background Art

[0002] In water conservancy projects and water treatment systems, the hydraulic rotary weir gate, as an efficient and precise water flow control device, is of great importance. Its core working principle skillfully combines the hydraulic transmission principle and mechanical structure design. Through the powerful hydraulic power generated by the driving device, it pushes the weir gate panel to flexibly adjust the angle around the preset rotation axis, thereby achieving precise control of the water flow rate.

[0003] However, in the actual application process, especially in complex and changeable usage environments, the hydraulic rotary weir gate faces many challenges. Chinese Patent CN214497827U discloses a new type of hydraulic rotary weir gate. When the weir gate operates in a water body containing a large amount of impurities, floating objects and other foreign matters, these foreign matters may approach and accumulate in the narrow gap between the gate panel and the door frame along with the water flow. These foreign matters, including but not limited to sediment, branches, plastic garbage, etc., will not only increase the frictional resistance during the opening and closing process of the gate panel, but may also directly jam the contact surface between the gate panel and the door frame, resulting in the obstruction or even complete failure of the opening and closing action. In the long run, frequent jamming will not only affect the normal working efficiency of the weir gate, but may also cause physical damage to the gate panel and the door frame, shorten the service life of the equipment, and increase the maintenance cost.

The telescopic rod of the hydraulic cylinder is rotatably connected to the hinge seat of the gate panel. A rubber water retaining belt is arranged on the gate panel. A counterweight is arranged at the end of the rubber water retaining belt.

[0007] Further, a first mounting seat is arranged at the top of the upper frame, and the hydraulic cylinder is rotatably connected to the first mounting seat.

[0008] Further, a rubber sealing strip is arranged at the edge of the side baffle, and the end of the rubber sealing strip abuts against the arc-shaped water retaining plate.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0016] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model. The present utility model will be further described in conjunction with the accompanying drawings and embodiments:

[0017] Such as Figure 1 - Figure 2As shown in the figure, a hydraulic rotary weir gate includes a foundation 1. Columns 2 are provided on both sides of the foundation. An upper frame 3 is provided at the top of the columns. The upper frame serves as an installation platform for the hydraulic cylinder, ensuring the stable operation of the hydraulic cylinder. A hydraulic cylinder 4 is rotatably connected to the upper frame. The hydraulic cylinder serves as a power source, and the opening and closing of the door panel are realized through the telescopic movement of the telescopic rod. A side baffle 5 is installed on the side wall of the column. A rotating shaft 62 is provided at the bottom of the side baffle. The rotating shaft serves as the rotation center of the door panel, enabling the door panel to rotate flexibly. A door panel 6 is rotatably connected to the rotating shaft. The door panel is the main part of the weir gate, and the regulation of water flow is realized through rotation. Arc-shaped water retaining plates 7 are provided on both sides of the door panel. The telescopic rod of the hydraulic cylinder is rotatably connected to the hinge seat 61 of the door panel. A rubber water retaining strip 83 is provided on the door panel. The rubber water retaining strip enhances the sealing performance of the door panel and effectively prevents water leakage. A counterweight 84 is provided at the end of the rubber water retaining strip.

[0018] In at least one embodiment, a first mounting seat 31 is provided at the top of the upper frame. The hydraulic cylinder is rotatably connected to the first mounting seat. The first mounting seat provides a stable mounting point for the hydraulic cylinder, ensuring the firm connection of the hydraulic cylinder.

[0019] In at least one embodiment, a rubber sealing strip 51 is provided at the edge of the side baffle. The end of the rubber sealing strip abuts against the arc-shaped water retaining plate. The rubber sealing strip further enhances the sealing performance of the side baffle and prevents water leakage from the side.

[0020] In at least one embodiment, as Figure 2 shown, a fixing plate 81 is fixedly connected to the door panel by bolts 82. The fixing plate provides a stable mounting foundation for the rubber water retaining strip, ensuring the firm connection of the rubber water retaining strip. The rubber water retaining strip is connected to the fixing plate. With the design of the rubber water retaining strip and the counterweight, the joint between the door panel and the rotating shaft can always be at the bottom of the rubber water retaining strip, avoiding debris from entering the joint.

[0021] Furthermore, a rubber raised sealing strip 63 is provided at the bottom of the door panel. Correspondingly, a groove 64 matching the rubber raised sealing strip is provided at the top of the foundation. The rubber raised sealing strip enhances the sealing performance at the bottom of the door panel and effectively prevents water leakage from the bottom.

[0022] Furthermore, when the door panel rotates to the vertical position under the action of the hydraulic electric cylinder, the rubber raised sealing strip can be clamped in the groove to achieve a sealing effect. This design ensures the tight fit of the door panel when closed and effectively prevents water leakage.

[0023] Working mode: When it is necessary to open the weir gate, start the hydraulic cylinder 4 to make the telescopic rod of the hydraulic cylinder extend or contract, thereby driving the door panel 6 to rotate around the rotating shaft 62. During the rotation of the door panel, the design of the rubber water stop belt 83 and the counterweight 84 ensures that the joint between the door panel and the rotating shaft is always at the bottom of the rubber water stop belt, preventing debris from entering. When the door panel rotates to the required angle, stop the operation of the hydraulic cylinder to keep the door panel stable. When it is necessary to close the weir gate, operate the hydraulic cylinder in reverse to turn the door panel back to its original position. When the door panel is completely closed, the rubber convex sealing strip 63 can be clamped in the groove 64 at the top of the foundation to achieve a sealing effect and prevent water from leaking from this place. Regularly check the working conditions of components such as the hydraulic cylinder, rotating shaft, and rubber water stop belt. If there is damage or aging, they should be replaced in time. Clean the debris between the door panel and the side baffle to keep it clean and airtight. Regularly check and tighten all bolts and connectors to ensure the structural stability.

Those skilled in the art should understand that the present invention is not limited by the above embodiments. The above embodiments and the descriptions in the specification only illustrate the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention will have various changes and improvements, and all these changes and improvements fall within the scope of protection required by the present invention.
