Description

Technical Field

[0001] This utility model relates to the field of rainwater and sewage treatment technology, specifically to a gantry mechanism for an intelligent rainwater and sewage diversion gate. Background Technology

[0002] Urban drainage systems are engineering facilities systems for treating and discharging urban sewage and rainwater, and are an integral part of urban public utilities. Urban drainage system planning is an integral part of urban master planning. Urban drainage systems typically consist of drainage pipes and sewage treatment plants. Under a system of separate sewage and rainwater management, sewage is collected through drainage pipes, sent to sewage treatment plants, and then discharged into water bodies or recycled; rainwater runoff is collected through drainage pipes and discharged into nearby water bodies.

[0003] Gates used for separating rainwater and sewage generally consist of a gantry mechanism and a gate. The side beams on both sides of the gantry mechanism serve as load-bearing components, requiring high structural strength and resistance to deformation. Existing side beams use U-shaped profiles, which bear loads such as water pressure and water flow impact through their own structure. This results in thicker profiles to meet the load-bearing requirements, leading to increased material usage and higher costs during gate manufacturing. Utility Model Content

[0004] To address the technical problems existing in the background art, this utility model provides a gantry mechanism for an intelligent rainwater and sewage diversion gate.

[0005] The technical solution of this utility model is as follows:

[0006] A gantry mechanism for an intelligent rainwater and sewage diversion gate includes two side beams that serve as guide rails for the gate plate. Each side beam is provided with several wall-mounted anchors, which are arranged vertically at intervals.

[0007] The wall anchor includes an L-shaped buckle plate, with both ends of the buckle plate extending horizontally towards the direction of the other side beam and the water-facing direction, respectively, and its plate surface is perpendicular to the side of the side beam. The inner side of the L-shaped buckle plate is fixedly connected to the outer side of the side beam away from the other side beam and the outer side of the side beam in the back-water direction.

[0008] An anchor plate is provided at the edge of the end of the buckle plate that extends in the direction of water flow. The surface of the anchor plate is parallel to the outer side of the side beam in the direction of water flow, and the surface of the anchor plate is provided with anchor holes.

[0009] Furthermore, the wall anchor includes two buckle plates, which are symmetrically arranged vertically, and the upper and lower edges of the anchor plates are respectively connected to the edges of the two buckle plates at the water-facing end.

[0010] Furthermore, the buckle plate includes a hook plate portion and a rib plate portion. The hook plate portion extends in the direction of the other side beam, and its edge on the water-facing side protrudes in the water-facing direction with a first connecting portion. The rib plate portion extends in the water-facing direction, and its edge on the side near the other side beam protrudes in the direction of the other side beam with a second connecting portion. Both the first connecting portion and the second connecting portion are connected to the side beam, and there is a distance between them at their close positions.

[0011] Furthermore, both the inner and outer edges of the L-shaped buckle are curved bends.

[0012] Furthermore, the first connecting part and the second connecting part are located at both ends of the arc-shaped bend on the inner side of the buckle plate.

[0013] Furthermore, the rib is a right-angled trapezoidal plate, with its side away from the edge beam being an inclined side, and the width of its end facing the water is greater than the width of its end facing away from the water.

[0014] Furthermore, the wall anchors between the two side beams are symmetrically arranged.

[0015] Furthermore, on each side beam, more than half of the wall anchors are concentrated at the bottom of the side beam.

[0016] Furthermore, the spacing between adjacent wall anchors located at the gate's closed position is smaller than the spacing between adjacent wall anchors at other positions.

[0017] Furthermore, a flow-limiting plate is provided between the water-facing surfaces of the two side beams. The flow-limiting plate is located on the front side of the gate when the gate is closed, and a flow-limiting hole is provided on the flow-limiting plate.

[0018] This utility model provides a gantry mechanism for an intelligent rainwater and sewage diversion gate. Through wall-mounted anchors, it simultaneously serves the function of wall-mounting and strengthening the side beams, thereby enhancing the stress deformation resistance at the bends of the side beams. Furthermore, it reduces the forming thickness of the side beams while meeting the same load-bearing requirements, thus lowering material costs. Attached Figure Description

[0024] like Figure 1 and Figure 2 As shown, this utility model embodiment provides a gantry mechanism for an intelligent rainwater and sewage diversion gate, including two side beams 1. The side beams 1 are U-shaped profile structures with a U-shaped cross-section, and the openings of the U-shaped cross-sections of the two side beams 1 are arranged opposite to each other, serving as guide grooves for the gate plate in the gate.

[0025] A top beam 2 can be connected between the top ends of the two side beams 1, and a bottom beam 3 can be connected between the bottom ends of the two side beams 1. The top beam 2 and the bottom beam 3 together with the two side beams 1 form a rectangular shape. The top beam 2 and the bottom beam 3 play a role in structural definition and support for the two side beams 1.

[0026] Each side beam 1 is provided with several wall anchors 4, which are arranged vertically at intervals.

[0027] The wall anchor 4 includes an L-shaped buckle plate 41. The two ends of the buckle plate 41 extend horizontally towards the direction of the other side beam 1 and the water-facing direction, respectively, and its plate surface is perpendicular to the side of the side beam 1. The inner side of the L-shaped buckle plate 41 is fixedly connected to the outer side of the side beam 1 away from the other side beam 1 and the outer side in the back-water direction.

[0028] An anchor plate 42 is provided on the edge of the end of the buckle plate 41 extending in the water-facing direction. The surface of the anchor plate 42 is parallel to the outer surface of the side beam 1 in the water-facing direction. Anchor holes 421 are provided on the surface of the anchor plate 42 for inserting anchor rods. The wall anchor 4 is anchored to the mounting wall through the anchor rods, thereby fixing the side beam 1 to the mounting wall.

[0029] In this embodiment, the buckle plate 41 is fixed to the side beam 1 by welding and hooks the side beam 1, thereby increasing the deflection of the side beam 1 and improving its resistance to deformation. In other words, while achieving the same deflection and resistance to deformation, the side beam 1 in this embodiment can reduce the thickness of the side beam 1 material compared to the traditional method, thus reducing costs.

[0030] In this embodiment, the wall anchor 4 includes two buckle plates 41 and one anchor plate 42. The two buckle plates 41 are arranged symmetrically at the top and bottom. The upper and lower edges of the anchor plate 42 are respectively connected to the edges of the two buckle plates 41 in the water-facing direction. The anchor hole 421 is located between the two buckle plates 41.

[0031] The two snap plates 41 of the wall anchor 4 form a hook-like structure, which further increases the load that the wall anchor 4 can withstand, thereby further enhancing the flexibility of the side beam 1.

[0032] In addition, the position and connection relationship of the two buckle plates 41 and the anchor plate 42 can make the anchor plate 42 bear the force in a balanced manner, so as to avoid the deflection moment between the anchor plate 42 and the buckle plate 41 when there is only one buckle plate 41, which would affect the structural strength of the wall anchor 4 itself, thereby improving the service life of the wall anchor 4 and the strengthening effect on the side beam 1.

[0033] The buckle plate 41 specifically includes a hook plate portion 411 and a rib plate portion 412. The hook plate portion 411 extends in the direction of the other side beam 1, and its water-facing edge has a first connecting portion 413 protruding in the water-facing direction. The rib plate portion 412 extends in the water-facing direction, and its edge near the other side beam 1 has a second connecting portion 414 protruding in the direction of the other side beam 1. Both the first connecting portion 413 and the second connecting portion 414 are connected to the side beam 1, and there is a distance between them at their close positions.

[0034] The first connecting part 413 and the second connecting part 414 are not only used as connecting parts for welding and provide material allowance during welding, but also have a distance between them so that the buckle plate 41 can cope with various curved and rounded edge beams 1, and facilitate the contact between the wall anchor 4 and the outer side of the edge beam 1.

[0035] The inner and outer edges of the L-shaped snap-on plate 41 are both curved bends to distribute the stress on the snap-on plate 41, preventing stress concentration at the bends and thus avoiding deformation. This improves the snap-on plate 41's resistance to deformation and enhances its reinforcement of the edge beam 1's flexibility. Here, the inner edge refers to the edge of the snap-on plate 41 that contacts the edge beam 1, and the outer edge is the edge in the opposite direction to the inner edge.

[0036] The first connecting part 413 and the second connecting part 414 are located at both ends of the arc-shaped bend on the inner side of the buckle plate 41.

[0037] The rib is a right-angled trapezoidal plate with an inclined side away from the edge beam 1, and its width at the water-facing end is greater than the width at the back-water-facing end. This improves the rib's bending resistance, torsional stiffness, and buckling resistance, increases the load that the buckle plate 41 can withstand, and thus strengthens the structural strength of the edge beam 1.

[0038] The wall anchors 4 between the two side beams 1 are symmetrically arranged to ensure the overall force balance of the gantry mechanism.

[0039] Since the lower part of the edge beam 1 is the main area subjected to water pressure, more than half of the wall anchors 4 on each edge beam 1 are concentrated in the lower part of the edge beam 1 to specifically increase the load-bearing capacity of the lower part of the edge beam 1. For the non-primary load-bearing areas in the upper part of the edge beam 1, a small number of wall anchors 4 are sufficient.

[0040] Furthermore, on each side beam 1, the spacing between adjacent wall anchors 4 corresponding to the gate closing position is smaller than the spacing between adjacent wall anchors 4 in other positions. That is, the wall anchors 4 are installed more densely in the lower part of the gantry mechanism and more sparsely in the upper part of the gantry mechanism, so as to specifically strengthen the deformation resistance of the side beam 1 and effectively play the role of the wall anchors 4.

[0041] In this embodiment, a flow limiting plate 5 is provided between the water-facing surfaces of the two side beams 1. The flow limiting plate 5 is located on the front side of the gate plate when the gate is closed. A flow limiting hole 51 is provided at the center of the flow limiting plate 5. When the gate is closed, the gate plate blocks the flow limiting hole 51.

[0042] On the water-facing surface of the flow restrictor 5, a sealing ring (not shown in the figure) is provided around the edge of the flow restrictor hole 51. The sealing ring abuts against the pipe wall of the water flow pipe, and the flow restrictor hole 51 corresponds to the inner hole of the water flow pipe.
