Abstract
Description
Technical Field
[0001] The present application relates to the technical field of municipal drainage equipment, and in particular to a municipal sewage pipe flap door that is easy to construct, install and maintain over a long period of time. Background Art
[0002] At present, the municipal sewage pipe network is a huge systematic project, in which the municipal sewage pipe network and the urban river are connected by overflow pipes, so the municipal sewage pipe network has quite a lot of overflow pipes. Due to social progress and the optimization of urban appearance, municipal sewage must not be discharged and must be included in the treatment of the sewage pipe network. Therefore, the overflow pipe is required not to discharge sewage into the river under normal circumstances. However, it is required that in special extreme circumstances (extremely heavy rain), the overflow pipe must be connected to the river for a long time to relieve the pressure of the pipe network and discharge water into the river.
[0003] The riverbed heights in the related technologies are not uniform, and the elevations of the overflow pipes built according to the river channels cannot be unified. In order to ensure that all overflow pipes do not discharge water into the river channels under normal circumstances, but can discharge water into the river channels under extreme circumstances, the current plan is to build overflow walls and flap gates at the overflow pipes in the river channels. Overflow pipes of different elevations are constructed with overflow walls of the same elevation to ensure that sewage is not discharged under normal circumstances. Flap gates are set. Under normal circumstances, the flap gates are opened to keep the overflow pipes connected to the river channels in preparation for discharging water into the river channels under extreme circumstances. When the water level in the river channels is higher than that of the overflow pipes under extreme circumstances, the flap gates may be closed to ensure that river water does not flow back into the pipe network through the overflow pipes.
[0004] With regard to the above-mentioned related technologies, the inventors believe that: the existing flap doors are traditional cast iron flap doors, which are heavy. Taking the commonly used DN800 cast iron flap door as an example, the overall mass is about 160kg, of which the mass of the cover plate accounts for more than 1 / 2 of the overall mass, that is, greater than 80kg. The installation is difficult, and once the flap door is partially corroded and damaged, it needs to be replaced as a whole, resulting in a waste of resources and subsequent maintenance difficulties. In addition, it is necessary to use masonry and cement to build an overflow wall inside the traditional cast iron flap door. Once the elevation of the masonry and cement overflow wall is determined, the elevation can only be adjusted by destructive demolition. Utility Model Content
[0005] The purpose of the present application is to provide a municipal sewage pipe flap gate which is easy to construct, install and maintain over a long period of time, so as to solve the problem that the existing flap gates are difficult to install, and once the flap gates are partially corroded and damaged, they need to be replaced as a whole, resulting in waste of resources and subsequent maintenance difficulties. In addition, it is also necessary to use bricks, stones and cement to build an overflow wall inside the traditional cast iron flap gate. Once the elevation of the overflow wall built with bricks, stones and cement is determined, the elevation can only be adjusted by destructive demolition.
[0006] The application provides a municipal sewage pipe flap door that is easy to build, install and maintain for a long time, which adopts the following technical solutions:
[0007] A municipal sewage pipe flap gate which is easy to construct, install and maintain over a long period of time, comprises an overflow wall and a flap gate body rotatably arranged on one side of the overflow wall, the flap gate body comprises a flap gate frame, a flip assembly is arranged between the top of the flap gate frame and the top of the overflow wall, a first module component fixing groove is arranged on one side of the flap gate frame, a plurality of first module components are arranged in the first module component fixing groove, and a support assembly is symmetrically arranged between the flap gate frame and the overflow wall to support the flap gate body.
[0008] Furthermore, the support assembly includes a support rod rotatably arranged on one side of the overflow wall, a support bracket is arranged on one end of the support rod, and a support fixing point cooperating with the support bracket is arranged on one side of the flap door frame.
[0009] Furthermore, a fastening groove is formed on one side of a plurality of first module components, and a fastening protrusion is formed on one side of a plurality of first module components away from the fastening groove, and the fastening protrusion cooperates with the fastening groove.
[0010] Furthermore, leak-proof rubber is provided on both the fastening protrusion and the fastening groove.
[0011] Furthermore, the flip assembly includes fixed blocks symmetrically arranged on the top of the overflow wall, a flip rod is rotatably arranged between the two fixed blocks, a plurality of connecting blocks are arranged on the rod body of the flip rod, and one end of each of the connecting blocks is connected to the top of the flap door frame.
[0012] Furthermore, the overflow wall includes an overflow wall frame, a second module component fixing groove and a second module component, the second module component fixing groove is arranged on one side of the overflow wall frame, a plurality of second module components are arranged, and a plurality of second module components are respectively arranged in the second module component fixing groove.
[0013] Furthermore, the second module component fixing groove has the same structure as the first module component fixing groove.
[0014] Furthermore, the second module component has the same structure as the first module component, and fastening grooves and fastening protrusions are also respectively provided on both sides of the second module component.
[0015] Compared with the prior art, the beneficial effect of the present application lies in that: by setting up a structure in which an overflow wall, a flap door frame, a flip assembly, a first module component fixing groove, a first module component and a support assembly cooperate with each other, several first module components can be respectively inserted into the first module component fixing grooves on the flap door frame to build the entire flap door structure. Therefore, through the modular split design, the independent first module components can achieve the effect of local replacement after local corrosion damage, and at the same time can further reduce the difficulty of installation, thereby reducing the waste of resources and reducing the difficulty of subsequent maintenance.
[0016] In addition, the overflow wall also adopts a modular split design. The independent second module components are compatible with the flap door, which can facilitate the adjustment of the elevation of the overflow wall, thus solving the problem that the overflow wall can only be destructively demolished when the elevation needs to be adjusted; it can also achieve the effect of local replacement after local corrosion damage.
[0017] Under normal circumstances, the deadweight of the flap door body causes the support assembly on the side of the overflow wall to bear pressure on the flap door body, and the pressure-bearing support assembly cannot rotate, forcing the flap door frame to be supported and opened. Under extreme circumstances, when the flap door frame and the first module component need to be closed, under the action of the flip assembly, the flap door frame and the first module component only need to be lifted upward, and the support assembly loses pressure and automatically slides down, thereby achieving the flap door frame and the first module component closing on one side of the overflow wall to close and block the overflow wall.

DETAILED DESCRIPTION
[0021] The following is combined with Figure 1-2 This application is described in further detail.
[0022] The present application embodiment discloses a municipal sewage pipe flap door which is easy to construct, install and maintain for a long time. Figure 1In this embodiment, the municipal sewage pipe flap gate includes an overflow wall 2, a flap gate body 1, a flip assembly and a support assembly. The overflow wall 2 is built at the river channel of the overflow pipe; one side of the flap gate body 1 is installed on the top of the overflow wall 2 through the flip assembly, and the flap gate body 1 is convenient for swinging and flipping on the overflow wall 2 through the setting of the flip assembly; there are two support assemblies, and the two support assemblies are symmetrically arranged between the overflow wall 2 and the flap gate body 1. The two support assemblies are convenient for stably supporting the flap gate body 1, so as to realize the opening or closing of the flap gate body 1.
[0023] Under normal circumstances, the deadweight of the flap door body 1 causes the support assembly on the side of the overflow wall 2 to bear pressure on the flap door body 1, and the pressure-bearing support assembly cannot rotate, and is forced to support the opening of the flap door body 1. When in extreme cases, the flap door body 1 needs to be closed, under the action of the flip assembly, it is only necessary to lift the flap door body 1 upward, and the support assembly loses pressure and automatically slides down, so that the flap door body 1 is closed on one side of the overflow wall 2 to close and block the overflow wall 2.
[0024] The structures of the flap door body 1, the overflow wall 2, the flip assembly and the support assembly are described in detail below:
[0025] Specifically, refer to Figure 1 and Figure 2 In this embodiment, the flap door body 1 includes a flap door frame 11, a first module component fixing groove 12 and a first module component 13. Among them, the top side of the flap door frame 11 is installed on the top of the overflow wall 2 through a flip assembly; the first module component fixing groove 12 is installed on the side of the flap door frame 11 away from the overflow wall 2; there are a plurality of first module components 13, and the plurality of first module components 13 are all rectangular structures, and the plurality of first module components 13 are respectively matched with the first module component fixing groove 12, so that the first module components 13 are sequentially inserted into the first module component fixing groove 12, so as to be stacked to form the flap door body 1.
[0026] Therefore, by setting a modular split design in which the flap door frame 11, the first module component fixing groove 12 and the first module component 13 cooperate with each other, the independent first module component 13 can achieve the effect of local replacement of the flap door body 1 after local corrosion and damage, and at the same time can further reduce the difficulty of installing the flap door body 1, thereby reducing the waste of resources and reducing the difficulty of subsequent maintenance.
[0027] More specifically, in the present embodiment, a fastening groove 9 is formed on one side of the first module components 13, and a fastening protrusion 10 is installed on the side of the first module components 13 facing away from the fastening groove 9. The fastening protrusion 10 and the fastening groove 9 are engaged with each other, so that the multiple first module components 13 can be stably spliced with each other, thereby improving the stability of the stacked flap door body 1.
[0028] Preferably, in this embodiment, leak-proof rubber is installed on the fastening protrusion 10 and the fastening groove 9. The provision of the leak-proof rubber can not only improve the stability between the multiple first module components 13, but also make the multiple first module components 13 fit more closely, thereby achieving an effective leak-proof effect.
[0029] At the same time, refer to Figure 1 and Figure 2 In this embodiment, the overflow wall 2 includes an overflow wall frame 21, a second module component fixing groove 22, and a second module component 23. The overflow wall frame 21 is built in the river channel; the second module component fixing groove 22 is installed on the side of the overflow wall frame 21 facing the flap door frame 11; there are a plurality of second module components 23, each of which is a rectangular structure, and the plurality of second module components 23 are respectively matched with the second module component fixing groove 22, so that the second module components 23 are sequentially inserted into the second module component fixing groove 22 to be stacked to form the overflow wall 2.
[0030] Therefore, by setting up a modular split design in which the overflow wall frame 21, the second module component fixing groove 22 and the second module component 23 cooperate with each other, the independent second module component 23 can also achieve the effect of partial replacement of the overflow wall 2 after local corrosion damage.
[0031] Preferably, in this embodiment, the second module sub-component fixing groove 22 has the same structure as the first module sub-component fixing groove 12; and the second module sub-component 23 has the same structure as the first module sub-component 13, that is, the second module sub-component 23 is also provided with a fastening groove 9 and a fastening protrusion 10 on both sides. In this way, the second module sub-component 23 and the first module sub-component 13 can be used interchangeably, thereby improving the convenience of installation.
[0032] At the same time, in this embodiment, the elevation of the overflow wall 2 can be easily adjusted through the snap-fitting of the plurality of second module components 23, thereby solving the problem that the overflow wall 2 can only be destructively demolished when the elevation needs to be adjusted.
[0033] In addition, refer to Figure 1In this embodiment, the support assembly includes a support rod 6, a support bracket 7 and a support fixing point 8. One end of the support rod 6 is rotatably mounted on one side of the overflow wall frame 21 through a rotating shaft; the support bracket 7 is mounted on one end of the support rod 6 away from the overflow wall frame 21; the support fixing point 8 is mounted on one side of the flap door frame 11, and the support fixing point 8 and the support bracket 7 cooperate with each other, so that the support bracket 7 on the support rod 6 is engaged with the support fixing point 8, so as to facilitate the flap door body 1 to be stably supported, and then facilitate the flap door body 1 to be opened.
[0034] In addition, refer to Figure 1 In this embodiment, the flip assembly includes a fixed block 3, a flip rod 4 and a connecting block 5. There are two fixed blocks 3, which are symmetrically mounted on the top of the overflow wall frame 21; the two ends of the flip rod 4 are rotatably mounted between the two fixed blocks 3; there are two connecting blocks 5, one side of the two connecting blocks 5 is fixedly connected to the rod body of the flip rod 4, and the sides of the two connecting blocks 5 facing away from the flip rod 4 are fixedly connected to one side of the top of the flap door frame 11.
[0035] By setting up a flip structure in which the fixed block 3, the flip rod 4 and the connecting block 5 cooperate with each other, the flap door body 1 can be rotated and flipped on one side of the overflow wall 2, so that under the action of the supporting component, the flap door body 1 can close or open the overflow wall 2.
[0036] The implementation principle of a municipal sewage pipe flap that is easy to construct, install and maintain over a long period of time in an embodiment of the present application is as follows: under normal circumstances, the deadweight of the flap door body 1 causes the support rods 6 and support brackets 7 on the side of the overflow wall 2 to bear pressure on the supporting fixed points 8 on the side of the flap door body 1, and the supported support rods 6 cannot rotate, forcing the flap door frame 11 to be supported and opened.
[0037] When in extreme cases, it is necessary to close the flap door frame 11 and the first module component 13, under the action of the flip assembly, it is only necessary to lift up the flap door frame 11 and the first module component 13, and the support bracket 7 on the support rod 6 will be separated from the support fixing point 8, so that the support rod 6 loses the pressure and automatically slides down, thereby achieving the closure of the flap door frame 11 and the first module component 13 on one side of the overflow wall 2 to seal and block the overflow wall 2.
[0038] The above description is only an embodiment of the present invention, and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made by using the contents of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
