Description

Technical Field

[0002] In the field of water conservancy projects and water resources management, hydraulic rotary weir gates are widely used in water level regulation, flow control, flood control and drainage as an efficient and precise water flow control device. Its core working principle is to use the hydraulic transmission principle to generate hydraulic power through the drive device to push the weir gate plate to adjust the angle around the rotation axis, thereby achieving precise control of the water flow.

DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. The utility model is further described in combination with the drawings and embodiments:

[0020] like Figure 1-Figure 2As shown, a hydraulic rotary weir gate connection component includes a door frame column 1, and a hinge seat 7 is installed at the bottom of the door frame column. The design of the hinge seat enables the arc-shaped connecting plate to rotate flexibly, thereby improving the convenience of operation of the weir gate. The hinge seat is rotatably connected with an arc-shaped connecting plate 5, and a side baffle 4 is provided on the door frame column. The side baffle effectively blocks debris in the water flow. A limit horizontal rod 41 is provided on the back of the side baffle, and in coordination with it, a limit swing rod 53 is provided on the left side of the back of the arc-shaped connecting plate. The limit swing rod can be rotated to abut against the limit horizontal rod, thereby limiting the rotation of the arc-shaped connecting plate around the hinge seat.

[0021] Furthermore, a rubber sheet 42 is installed at the edge of the side baffle, and the edge of the rubber sheet abuts against the surface of the arc-shaped connecting plate. The design of the rubber sheet increases the sealing between the side baffle and the arc-shaped connecting plate, and prevents water leakage.

[0022] In at least one embodiment, the back of the arc-shaped connecting plate is provided with a plurality of reinforcing ribs 51. The reinforcing ribs enhance the bearing capacity and anti-deformation capacity of the arc-shaped connecting plate and extend its service life.

[0023] Furthermore, a rotating shaft is provided on the hinge seat, and a rotating hole 52 for accommodating the rotating shaft to pass through is provided on the arc-shaped connecting plate.

[0024] In at least one embodiment, an upper bracket 3 is provided on the top of the door frame column, and the upper bracket provides a stable support point for the hydraulic cylinder to ensure the normal operation of the hydraulic cylinder. An end mounting seat 31 is provided on the upper bracket.

[0025] Further, the end mounting seat is rotatably connected with a hydraulic cylinder 6. The hydraulic cylinder provides a strong power support, making the opening and closing of the weir gate more rapid and accurate.

[0026] In at least one embodiment, an upper connecting plate 11 is provided on the top of the door frame column, and an upper bracket is installed on the upper connecting plate.

[0027] In at least one embodiment, a lower connecting plate 12 is provided at the bottom of the door frame column, and a hinge seat 7 is installed on the lower connecting plate.

[0028] In at least one embodiment, a door panel 2 is installed between the two arc-shaped connecting plates, a rotatable mounting seat 21 is provided on the door panel, and the telescopic rod of the hydraulic cylinder is rotatably connected to the rotatable mounting seat.

[0029] The hydraulic rotary weir gate connecting component is mainly driven by a hydraulic cylinder to realize the opening and closing of the rotary weir gate. The specific working method is as follows: when water needs to be discharged, the hydraulic cylinder starts to work, and its telescopic rod pushes the rotating mounting seat, thereby driving the door panel to rotate. Since the door panel is connected to the arc-shaped connecting plate, the arc-shaped connecting plate will also rotate around the hinge seat, thereby opening the rotary weir gate to discharge water. In this process, although debris will contact the arc-shaped connecting plate for a short time, under the high-speed impact of the water flow, the debris will be directly washed away and will not adhere to the surface of the arc-shaped connecting plate. At this time, the arc-shaped connecting plate is against the limiting horizontal rod of the side baffle through the limiting swing rod, thereby limiting its rotation around the hinge seat. At this time, the edge of the rubber sheet has been against the surface of the arc-shaped connecting plate, which plays a role in sealing and removing debris.

[0030] When the water level drops and the water stops flowing, the hydraulic cylinder drives the rotating weir gate to return to its original position. At this time, the rubber sheet plays the role of clearing debris again.

[0031] The above shows and describes the basic principles, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions in the specification are only to illustrate the principles of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the protection required by the utility model.
