Description

Technical Field

[0001] The invention belongs to the technical field of pipe and canal sewage treatment, and in particular relates to an interception system for a rainwater pipe and canal entering a sea ditch. Background Art

[0002] The interception system of the stormwater pipe into the sea ditch, as the name implies, is used to intercept garbage and floating objects in the stormwater pipe to prevent it from being discharged to the downstream and polluting the ocean, and at the same time effectively prevent the backflow of sea sand into the stormwater pipe. Located near the sea ditch outlet of coastal cities, a large amount of floating debris is discharged to the downstream of the stormwater pipe during the rainy season, which eventually reduces the drainage capacity of the pipe and pollutes the seawater. At the same time, the backflow of sea sand also causes the blockage of the stormwater pipe at the sea outlet. Therefore, it is imperative to manage the stormwater pipe at the sea ditch outlet.

[0003] At present, the existing technology builds garbage grilles at the river outlet, which requires regular manual cleaning. As for the garbage interception problem at the outlet of the rainwater pipe, only nylon mesh is set up to intercept floating garbage and waste, and regular manual cleaning is carried out. The environmental sensory perception is poor and it is impossible to achieve effective interception and control in the early stage. The backflow of silt at the outlet of the rainwater pipe depends on manual cleaning. Only relying on manual cleaning of the backflow of silt cannot effectively control the re-blocking of the tide, resulting in multiple manual cleaning. If a temporary interception net is set up at the outlet to intercept upstream debris, it will require multiple manual cleaning.

[0004] In view of this, the present invention is proposed. Summary of the invention

[0005] The present invention provides an interception system for a rainwater pipe entering a sea ditch to solve the technical problems raised in the above-mentioned background technology.

[0019] 1. The interception system for the entrance of a rainwater pipe into the sea provided by the present invention can intercept large suspended solids through a preliminary interception device while ensuring water flow when a rainstorm occurs. The interception facility is divided into two parts: the bottom interception facility is in a grid shape, which can intercept heavy dirt and floating objects, and the upper interception facility is in a grid shape, which can intercept floating garbage with low density and large volume while ensuring water flow capacity. Compared with setting up interception facilities at the river mouth, it can achieve initial control of pollutants.

[0020] 2. The present invention provides an interception system for the entrance of a rainwater pipe into the sea ditch. After a heavy rain, the movable cover is opened by operating the electric control cabinet to control the hydraulic rod, and the electric control cabinet is operated to control the lifting structure to lift the interception facility to the ground, and the garbage is dumped for collection and transportation. Compared with manual cleaning of floating garbage after rain, an automatic mode is realized. At the same time, after cleaning the garbage in the interception facility, the electric control cabinet controls the lifting structure to reset the preliminary interception device and the deep interception device. This process realizes automatic electric control, has good interception effect, is easy to operate, and greatly reduces the pollution of floating garbage in the rainwater pipe to the sea outlet. Compared with traditional manual cleaning, automatic reset can be achieved, which is efficient and fast.

DETAILED DESCRIPTION

[0032] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. The components of the embodiments of the present invention generally described and shown in the drawings here can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present invention provided in the drawings is not intended to limit the scope of the claimed invention, but merely represents the selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without making creative work belong to the scope of protection of the present invention.

[0033] like Figure 1-6 As shown, an embodiment of the present invention provides an interception system for a rainwater pipe entering a sea ditch, comprising a preliminary interception device 1, a deep interception device 2 and a backflow prevention device 3 arranged in sequence along the water flow direction;

[0034] The preliminary interception device 1 and the deep interception device 2 are both arranged in the rainwater pipe through the limiting I-beam clamps 4 located on the two side walls of the rainwater pipe; the preliminary interception device and the deep interception device both include bottom interception and upper interception, the bottom interception is a grid shape, and the upper interception is a grille shape.

[0035] like Figure 2Pre-buried base steel plates 101 are provided at both ends of the preliminary interception facility 1, and are divided into two parts, namely a preliminary interception bottom structure 103 and a preliminary interception upper mechanism 104. A U-shaped dirt cleaning interception mechanism 102 is connected to the bottom mechanism, and an equipment lifting hole 105 is provided on the top of the pipe channel above the interception system. A movable cover plate 114 is provided on the lifting hole. The movable cover plate is provided with a movable cover plate central axis 110, which can make the cover plate rotate upward around the central axis, and the movable cover plate 118 is opened by a hydraulic rod electric actuator 106. This process can be manually or automatically opened by the lifting equipment electric control cabinet 107, and a cable 108 is connected between the movable cover plate electric control cabinet 107 and the hydraulic rod electric actuator.

[0036] A lifting mechanism is provided on the downstream side of the preliminary interception device 1, and the lifting mechanism includes a lifting structure limiter 114. A lifting mechanism electric actuator 115 is provided inside the lifting structure limiter 114. The lifting structure limiter 114 is connected to a linkage rod 116 with a bidirectional electric roller 117. The overall structure of the lifting structure limiter 114 is controlled by a lifting equipment electric control cabinet 111. The lifting equipment electric control cabinet 111 and the lifting structure limiter 114 are connected by a cable 112. Considering that it is set in an underwater environment, a waterproof and anti-corrosion protective coating 113 is applied to the outside of the cable.

[0037] The water discharged from the preliminary interception device 1 passes through the deep interception device 2. Pre-buried base steel plates 101 are set at both ends of the deep interception device 2, and the upper and lower parts are respectively a deep interception bottom structure 203 and a deep interception upper mechanism 204. A U-shaped dirt cleaning interception mechanism 102 is connected to the bottom mechanism, and an equipment lifting hole 105 is set on the top of the pipe channel above the interception system. A movable cover plate 114 is set on the equipment lifting hole 105. The movable cover plate is provided with a movable cover plate central axis 110, which can make the cover plate rotate upward around the central axis, and the movable cover plate 118 is opened by the hydraulic rod electric actuator 106. This process can be manually or automatically opened by the lifting equipment electric control cabinet 107, and the cable 108 is connected between the movable cover plate electric control cabinet 107 and the hydraulic rod electric actuator.

[0038] A lifting structure limiter 114 is arranged on the downstream side of the deep interception facility, and a lifting mechanism electric actuator 115 is arranged inside the limiter. The lifting structure limiter 114 is connected to a linkage rod 116 with a bidirectional electric roller 117. The overall structure of the lifting structure limiter is controlled by an electric control cabinet 111 of the lifting equipment. The control cabinet and the lifting structure limiter are connected by a cable 112. Considering that it is arranged in an underwater environment, a waterproof and anti-corrosion protective coating 113 is applied to the outside of the cable.

[0039] The water that passes through the two interception facilities enters the sea outlet. In order to prevent the backflow of sea sand after high tide, a backflow prevention device 3 is set at the sea outlet. The backflow prevention device 3 is mainly composed of a movable valve plate body 301, a movable valve plate center axis 302 and a soft seal 304. The backflow prevention mechanism is installed and connected to the top and bottom of the rainwater pipe, and is fixed by the upper embedded angle steel 303 and the bottom embedded angle steel 305. The upstream side of the movable valve plate body is provided with a bottom embedded angle steel 305, which is buried in the bottom plate of the rainwater pipe. The bottom embedded angle steel is used to prevent the movable valve plate body from rotating upstream.

[0040] In the present invention, the upper embedded angle steel 303 and the bottom embedded angle steel 305 are both arranged in the concrete foundation 5 of the rainwater pipe channel.

[0041] To sum up, when using the rainwater pipe interception system, first fix the preliminary interception device 1, the deep interception device 2 and the backflow prevention device 3 in sequence along the water flow direction, and lock and install the facilities and the pipes through the matching fasteners. After the heavy rain, operate the movable cover electric control cabinet 107 to control the hydraulic rod electric actuator 106 to open the movable cover, and then operate the equipment to lift the electric control cabinet 111 to control the lifting structure limiter. The limiter is connected to the two-way electric roller 117 to lift the preliminary interception device 2 and the deep interception device 3 clockwise, and the garbage is collected and transported out. After cleaning the garbage in the interception facility, the limiter 114 is connected to the two-way electric roller 117 to lower the preliminary interception device 2 and the deep interception device 3 counterclockwise for reset.

[0042] Preferably, the grid density of the bottom interception in the preliminary interception device is smaller than the grid density of the bottom interception in the deep interception device.

[0043] Preferably, the grid density of the upper interception in the preliminary interception device is smaller than the grid density of the upper interception in the deep interception device.

[0044] The rainwater pipe interception system provided by the present invention can intercept large suspended solids while ensuring water flux through the preliminary interception device when heavy rain occurs. The interception facility is divided into two parts: the bottom interception facility is in a grid shape, which can intercept dirt and floating objects with a large specific gravity, and the upper interception facility is in a grid shape, which can intercept floating garbage with a small density and a large volume while ensuring water flow capacity. Compared with setting up interception facilities at the mouth of rivers and seas, it can achieve initial control of pollutants. It should be noted that the grid density of the bottom interception in the preliminary interception device is smaller than the grid density of the bottom interception in the deep interception device. The grid density of the upper interception in the preliminary interception device is smaller than the grid density of the upper interception in the deep interception device. In this way, the deep interception device can further intercept floating garbage with a smaller volume.

[0045] After heavy rain, the movable cover is opened by operating the movable cover electric control cabinet 107 to control the hydraulic rod electric actuator 106, and at the same time, the equipment lifting electric control cabinet 111 is operated to control the lifting structure limiter, and the limiter is connected to the two-way electric roller 117 to lift the preliminary interception facility 2 and the deep interception facility 3 clockwise, and the interception facilities are lifted to the ground, and the garbage is dumped for collection and transportation. Compared with manual cleaning of floating garbage after rain, an automatic mode is realized.

[0046] After cleaning the garbage in the interception facility, the stopper 114 connects the bidirectional electric roller 117 to counterclockwise descend the preliminary interception facility 2 and the deep interception facility 3 to reset. This process realizes on-site manual and automatic electric control, has good interception effect, is easy to operate, and greatly reduces the pollution of floating garbage in the rainwater pipe to the sea outlet. Compared with traditional manual cleaning, it can achieve automatic reset, which is efficient and fast.

[0047] The backflow prevention device opens the movable valve plate during heavy rain and closes the movable valve plate during non-water periods, which can effectively prevent the backflow of sea sand after high tide. Compared with the traditional nylon net interception and manual cleaning of pollution and sand at the ditch mouth, it saves manpower and has a good treatment effect.

In addition, the terms "first", "second", "third", etc. are only used to distinguish the description, and cannot be understood as indicating or implying relative importance.

[0049] In addition, the terms "horizontal", "vertical", "overhanging" and the like do not mean that the components are required to be absolutely horizontal or overhanging, but can be slightly tilted. For example, "horizontal" only means that its direction is more horizontal than "vertical", and does not mean that the structure must be completely horizontal, but can be slightly tilted.
