Description

Technical Field

[0001] The utility model relates to the technical field of rotary weirs, in particular to a process-sealed rotary weir. Background Art

[0002] Rotating weir gates are suitable for box culverts, channel outlets, intercepting wells, regulating reservoirs, and landscape water level storage in rivers. They are mainly used for intercepting and storing water, intercepting sewage, emergency flood discharge, regulating upstream water levels, controlling drainage flow, and preventing river backflow. The working environment of rotating weir gates is mostly in outdoor rivers or canals.

[0003] However, most of the existing rotating weir gates adopt an in-place sealing setting, that is, the rotating weir can only stop water after it is completely closed and in contact with the weir wall, making it impossible to adjust the water storage height of the intercepted object by adjusting the opening angle of the weir gate, which is not conducive to precise regulation and is not conducive to rapid water stopping when quick closure is required; and most of the sealing strips on the existing rotating weir gates are non-detachable, which makes the operation more cumbersome when the sealing strips need to be replaced after aging after long-term use.

DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] See also Figure 1-6 The utility model provides a technical solution: a process-sealed rotary weir, comprising a weir gate 1, one side of the weir gate 1 being rotatably connected to a wall via an oil cylinder 2, the oil inlet of the oil cylinder 2 being connected to the oil outlet of an external oil pump; a P-type sealing strip 3 is provided at the outer edge of the weir gate 1, and a second sealing strip 4 is provided on the wall; after the weir gate 1 is closed, the P-type sealing strip 3 contacts and squeezes the second sealing strip 4, thereby improving the sealing performance of the weir gate 1 after it is closed. The weir gate 1 is provided with a pressure plate 5 for limiting and fixing the P-type sealing strip 3. Through the setting of the pressure plate 5, the position of the P-type sealing strip 3 can be adjusted easily, and it is also convenient to replace it; the P-type sealing strip 3 passes through the bottom inner side of the weir gate 1 and is designed in a "U" shape; an adjustment shaft 8 is rotatably provided on the outer bottom of the weir gate 1, and a P-type sealing strip 2 9 is fixedly provided on the outer surface of the adjustment shaft 8, wherein the end of the P-type sealing strip 2 9 is fixedly connected to the P-type sealing strip 1 3; through the synergistic effect of the P-type sealing strip 3 and the P-type sealing strip 2 9, the bottom of the weir gate 1 still has a strong sealing performance when it is rotated at a certain angle, and the adjustment shaft 8 and the P-type sealing strip 2 9 at the bottom of the weir gate 1 cooperate to prevent water leakage during rotation.

[0026] For this purpose, the P-type sealing strip 1 (3) on weir gate 1 is positioned flush against the wall, ensuring a tight seal at any angle during the weir gate 1's closing process. The protruding portions of the P-type sealing strip 1 (3) and the P-type sealing strip 2 (9) are located between the pressure plate 5 and the weir gate 1, securing the P-type sealing strip 1 (3) and the P-type sealing strip 2 (9) thereto.

[0027] For this explanation, the bottom of the weir gate 1 and its edge close to the wall extend outward to form a protrusion, and the P-type sealing strip 3 is located between the protrusion and the pressure plate 5. By adjusting the position of the pressure plate 5, the P-type sealing strip 3 is fixed between the pressure plate 5 and the protrusion to prevent the P-type sealing strip 3 from falling.

[0028] Among them, regarding the installation scheme of the second sealing strip 4 and the weir gate 1, a connecting plate 6 is fixedly provided on the wall, and the second sealing strip 4 is fixedly provided on the side of the connecting plate 6 close to the weir gate 1. The setting of the connecting plate 6 improves the stability of the second sealing strip 4 during use.

[0029] An adjusting plate 101 is rotatably provided at the bottom of the weir gate 1 , and a locking member for fixing the weir gate 1 is provided on the adjusting plate 101 .

[0030] Among them, regarding the design scheme of the locking member, the locking member includes a limit plate 102 fixedly set on the wall, a limit block 103 fixedly set on the limit plate 102, a fixed screw 104 is threaded through the limit block 103, and the end of the fixed screw 104 is rotatably set with the adjustment plate 101; by rotating the fixed screw 104, the position of the adjustment plate 101 on the limit plate 102 is adjusted, and the adjustment plate 101 drives the weir gate 1 to move synchronously to achieve the adjustment of the position of the weir gate 1. A fixed waist hole 105 is opened through the adjustment plate 101, and a limit screw 106 is set through the fixed waist hole 105. The limit screw 106 is threadedly connected to the inner surface of the limit plate 102. After the position adjustment of the weir gate 1 is completed, the limit screw 106 is rotated to gradually insert it into the interior of the limit plate 102, thereby clamping and fixing the adjustment plate 101 to improve the stability of the weir gate 1.

[0031] In this description, the bottom of the adjustment plate 101 slides with the surface of the limiting plate 102, thereby improving the stability of the adjustment plate 101 during installation. The length of the fixing waist hole 105 is greater than the diameter of the limiting screw 106, and the width is smaller than the diameter of the limiting screw 106.

[0032] Regarding the design of connector 7, it includes multiple connecting blocks 701 fixed to weir gate 1. The size and shape of connecting blocks 701 can be adjusted according to actual needs. Adjusting screws 702 are threaded through the interior of connecting blocks 701. The ends of adjusting screws 702 are rotatably connected to pressure plate 5. By rotating adjusting screws 702, pressure plate 5 moves along the surface of weir gate 1, adaptively adjusting the distance between pressure plate 5 and the protrusion according to the size of P-type sealing strip 3, thereby achieving a stable installation of P-type sealing strip 3.

[0033] As a further technical solution, the pressure plate 5 is provided with a plurality of adjustment holes 703, each of which is provided with an adjustment screw 704. The adjustment screw 704 extends into the interior of the weir gate 1 and is threadedly connected to the inner surface of the weir gate 1. The provision of the adjustment screw 704 facilitates further limiting and fixing the position of the pressure plate 5. The provision of the adjustment holes 703 ensures that the position of the pressure plate 5 can be adjusted without causing motion interference, and after adjustment, the adjustment screw 704 can be used to rotate and fix it again.

[0034] As a further technical solution, the length of the adjusting waist hole 703 is greater than the diameter of the adjusting screw 704 , and the width is smaller than the diameter of the adjusting screw 704 .
