Examples

As shown in fig. 1-4, a drainage inspection well for preventing sludge accumulation comprises a well body 7 of the drainage inspection well, two pipeline installation ports 1 which are communicated with the inside of the well body 7 and are oppositely arranged are arranged on the outer wall of the well body 7, two pipelines of external fluid are hermetically connected on the pipeline installation ports 1, a rotating shaft 14 is coaxially and rotatably connected in the well body 7, specifically, a hollow installation frame 8 is installed on the inner wall of the well body 7, the rotating shaft 14 is rotatably connected on the installation frame 8 through an installation bearing and keeps a coaxial state with the well body 7, a plurality of turnover pieces 12 are arranged on the rotating shaft 14 along the axial array of the rotating shaft, the positions of the turnover pieces 12 correspond to the positions of the pipeline installation ports 1, so that after fluid in the pipelines installed on the pipeline installation ports 1 enters the well body 7, impact force is generated on the turnover pieces 12, and the rotating shaft 14 is driven by the turnover pieces 12 to rotate, 14 lower extreme of pivot extends to in the tip of the well body 7 lower extreme and the array is equipped with a plurality of stirring paddles 15, when pivot 14 rotates, the drive is a plurality of stirring paddles 15 stirs the mud of siltation bottom in the well body 7, makes mud stir and toward the upper end of the well body 7 flows, flows extremely during 1 department of tube-line erection mouth, fluid in the pipeline of installation on 1 of tube-line erection mouth washes mud into another pipeline and walks away side by side.

In this embodiment, the outer contour of the turning piece 12 is preferably substantially arc-shaped, so that when the fluid impacts the turning piece 12, the turning piece 12 can be better driven to rotate, and the rotating shaft is further driven to rotate.

In this embodiment, it is preferable that a reinforcing plate 13 is commonly connected between two adjacent flip pieces 12, and since the flip pieces 12 receive the impact force of the fluid for a long time, the reinforcing plate 13 is provided to increase the impact strength of the flip pieces 12 in order to prevent the flip pieces 12 from being deformed due to impact bending.

In this embodiment, as preferred, upset piece 12 bottom surface is located pipeline installation mouth 1 axle center top, makes upset piece 12 can not block the flow of fluid in pipeline installation mouth 1, if upset piece 12 blocks pipeline installation mouth 1, the fluid in the pipeline will unable rapid circulation like this, lead to influencing the conveying efficiency of pipeline, consequently in order to avoid influencing the circulation efficiency of pipeline, set up upset piece 12 bottom surface and be located the top of pipeline installation mouth 1 axle center, the fluid in pipeline installation mouth 1 can pass through and can produce the impact to upset piece 12 like this, and then under the circumstances of guaranteeing to produce the impact to upset piece 12, compromise the circulation of fluid, and then improved the practicality.

In this embodiment, as preferred, the well body 7 oral area articulates there is well lid 10, just well lid 10 passes through its upset along the articulated department with the well body 7 of drive arrangement drive, well lid 10 top be equipped with run through it and with the inside viewing aperture 11 that communicates of the well body 7, the operation in-process, need the workman in time to observe the fluid flow state in the well body 7, consequently set up viewing aperture 11 on well lid 10 for can see through viewing aperture 11 and in time observe fluidic circulation state.

In this embodiment, preferably, the manhole cover 10 is hinged to the manhole body 7 through the installation hinges 6, and the installation manner of the hinges 6 is used, so that the operation steps of installing the manhole cover 10 are relatively simple and more humanized.

In this embodiment, preferably, the driving device includes a fixed frame 16 disposed on an outer wall of the well body 7, the fixed frame 16 is hinged to a mounting base 3, a telescopic cylinder 4 is mounted on the mounting base 3, a movable block 5 is drivingly connected to the telescopic cylinder 4, a roll-over stand 9 is disposed on a side of the well lid 10 adjacent to a hinged portion of the well lid 10 with the well body 7, the roll-over stand 9 is hinged to the movable block 5, when the well lid 10 needs to be opened, the telescopic cylinder 4 is directly started, a cylinder rod of the telescopic cylinder 4 is shortened, the movable block 5 pulls the roll-over stand 9 to turn over downwards, the well lid 10 is further turned over along the hinged portion with the well body 7, an opening of the well body 7 is in an open state, when the well lid 10 needs to be closed, the telescopic cylinder 4 is started again, the cylinder rod of the telescopic cylinder 4 is extended, the well lid 10 is driven to turn over reversely, and, the driving device is arranged to open and close the well lid 10, so that a worker is not required to manually open/close the well lid 10, the labor intensity of workers is reduced, and certainly, the telescopic cylinder 4 can be replaced by a driving element such as an electric push rod or an oil cylinder, and the implementation is not affected, so that the type of the driving element for driving the movable block 5 to move can be expanded to a certain degree.

In this embodiment, as preferred, be equipped with the protection casing 2 that is used for protecting drive arrangement on the 7 outer walls of well body, the 2 oral area of protection casing opens and is suitable for the screw connection on 7 outer walls of well body, because the well body 10 is generally installed below the earth's surface, consequently need protect parts such as telescopic cylinder 4 among the drive arrangement, avoid influencing telescopic cylinder 4's normal use and life, 2 oral areas of protection casing are preferably located above the earth's surface, avoid in the material such as earth gets into protection casing 2, can inject the material of protection casing 2 for corrosion-resistant metal material in addition, for example stainless steel or the sheet metal of surface galvanization do, can avoid moisture to influence the corrosion of protection casing 2 like this.

The principle and the advantages of the invention are as follows: after the fluid in the pipeline flows into the well body 7, because the fluid has certain flow velocity, impact will be produced to the turning sheet 12, the turning sheet 12 that receives the impact will produce the rotation around 14 axial of pivot, and then make the pivot 14 also produce and rotate, when the pivot 14 rotates, the stirring rake 15 of its lower extreme installation will produce the stirring effect to the mud that deposits on the bottom in the well body 7, the mud that receives after stirring will be flipped to the mouth part direction of the well body 7, when flipping to the position department of pipeline installation mouth 1, will be driven by the fluid and flow into next pipeline, make mud can empty voluntarily, avoid depositing in the well body 7.

Finally, it should be noted that: although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that changes may be made in the embodiments and/or equivalents thereof without departing from the spirit and scope of the invention.
