Embodiment 1

[0041] see figure 1 , figure 2 , image 3 and Figure 4 As shown, the present embodiment discloses a bottom opening weir gate, comprising:

[0042] Weir frame assembly 1, the bottom of weir frame assembly 1 is provided with weir plate via hole, the side of weir frame assembly 1 is provided with flow hole 10, and the inside of weir frame assembly 1 is provided with accommodating space;

[0043] The weir plate 2, the weir plate 2 passes through the weir plate hole, the weir plate 2 is slidably installed in the accommodation space of the weir frame assembly 1, and the weir plate 2 can at least partially cover the flow hole 10, surround the flow hole 10, the weir plate Seals 4 are provided between both sides of the weir plate 2 and the components of the weir plate 2. When the weir plate 2 slides upward, the flow hole 10 is closed. When the weir plate 2 slides downward, the flow hole 10 is opened. The top of the weir plate 2 in the embodiment is provided with a U-shaped water ...

Embodiment 2

[0047] see Figure 6 As shown, on the basis of Embodiment 1, the weir frame assembly 1 of the bottom-opening weir gate of this embodiment includes a frame body formed by buckling the first weir frame 11 and the second weir frame 12, and the bottom of the frame body Form the weir plate through holes, the first weir frame 11 and the second weir frame 12 are provided with flow holes 10, and the first guide device and the second guide device arranged in the frame, the two sides of the weir plate 2 are respectively Slidably connected to the first guide and the second guide.

[0048] The structure of the first guiding device and the second guiding device in this embodiment is the same. In this embodiment, the first guiding device is used as an example for illustration. The first guiding device includes two guiding bars 14 located in the frame. A chute is provided, two guide strips 14 are arranged oppositely, a slide plate is fixedly installed on the side of the weir plate 2, and th...

Embodiment 3

[0059] The difference between embodiment 3 and embodiment 2 is: the frame body in embodiment 2 is formed by fastening the first weir frame 11 and the second weir frame 12;

[0060] The frame body in embodiment 3 is an integral structure formed by welding two frames and a panel. Both the bottom and top of the panel can be flush with the top or bottom of the bezel, or not. The bottom of the panel in this embodiment is flush with the bottom of the frame, the top of the panel is lower than the top of the frame, and the flow hole 10 is a square hole or a circular hole.

[0061] Further, the weir frame assembly 1 also includes a bottom plate, on which weir plate holes are opened, and the bottom plate is located at the bottom of the frame and is fixedly connected to the frame. When the bottom of the panel is flush with the bottom of the frame, the bottom plate is located at the bottom of the frame and the panel, and is fixedly connected with the bottom of the frame and the panel.

Abstract

The invention discloses a lower-opening type weir gate. The lower-opening type weir gate comprises a weir frame assembly, a weir board and driving mechanisms; a weir board through hole is formed in the bottom of the weir frame assembly, an overflowing hole is formed in the side surface of the weir frame assembly, and a containing space is arranged in the weir frame assembly; the weir board passesthrough the weir board through hole and is slidably installed in the containing space of the weir frame assembly and surrounds the overflowing hole, sealing pieces are arranged between the two sides of the weir board and the weir board assembly correspondingly, when the weir board slides upwardly, the overflowing hole is closed, and when the weir board slides downwardly, the overflowing hole is opened; and the driving mechanisms are connected with the weir board and used for driving the weir board to slide in the weir board assembly. The lower-opening type weir gate is of a four-sided sealingstructure and can be applied to an outlet, a pollutant intercepting pipe or an initial rain pipe, the applying range is wide, and security and reliability are achieved.

Description

technical field [0001] The invention relates to the technical field of water supply and drainage, in particular to a bottom-opening weir gate. Background technique [0002] The Chinese patent application number is 201420357758.6 and it is disclosed in the name of the hydraulic down-opening weir gate. The hydraulic down-opening weir gate includes a weir gate frame and a weir gate weir plate that cooperates with the weir gate frame. The middle part of the weir gate frame has a Groove, the two sides of the groove are guide grooves, the two sides of the weir door plate slide with the guide groove, the bottom passes through the weir gate frame, and a hydraulic cylinder is arranged in the weir gate frame, and the piston rod of the hydraulic cylinder is connected to the weir gate weir plate. The weir gate frame is a U-shaped frame, with a frame bottom plate at the bottom, and a weir plate hole is opened on the frame bottom plate. The weir plate passes through the weir plate hole, a...
