Description

Devices for decontamination of sewer pipes

technical field

The utility model relates to a decontamination technology for drainage pipes, in particular to a device for decontamination of drainage pipes.

Background technique

With the rapid development of my country's social economy and the continuous improvement of the level of urbanization, the discharge of urban sewage continues to increase; with the increase of sewage discharge, a large number of impurities also enter the drainage pipes under the influence of sewage. The sedimentation in the pipeline will cause pipeline blockage, bring environmental pollution, bring inconvenience to people's life and work, and cause economic losses.

At present, common methods for desilting drainage pipelines include slow vehicle desilting, high-pressure water jet desilting and manual desilting.

The working principle of the slow car dredging method is: first pass the TT sheet through the pipe section to be cleaned, and then use the transmission device to twist the wire rope back and forth, so as to drive the dredging tool to scrape the silt into the downstream inspection well, and then achieve the goal of clearing the pipeline Effect. This method has a good dredging effect on pipelines with severe silt and dense silt bonding; its disadvantage is that it needs to manually go down the well to install TT sheets, which is difficult to operate and has potential safety hazards.

The working principle of the high-pressure water jet dredging method is: the water jet head is set in the pipeline, and the vehicle-mounted booster device provides high-pressure water flow to the water jet head through the water pipe. The water jet nozzle moves to clean the pipeline; the disadvantages of this method are: large water consumption, high operating cost and low efficiency.

Manual cleaning means sending workers into the pipeline for cleaning. Although this method is effective, the work efficiency is very low, and because there are a lot of toxic and harmful gases in the sewage pipeline, it not only affects the health of the workers, but also has potential safety hazards. .

Utility model content

Aiming at the content in the background technology, the utility model proposes a device for cleaning the drainage pipes, the structure of which is: the device is composed of two support rods, two connecting columns, a flip door and two limit ropes ; One end of the support rod is connected to the middle of the connecting column to form a T-shaped support frame, the two T-shaped support frames are parallel to each other, the axial direction of the connecting column is perpendicular to the horizontal direction, the axial direction of the supporting rod is parallel to the horizontal direction, and the lower end of the connecting column is in contact with the bottom of the pipe The connecting column is provided with a rotating pin, and the rotating pin is located below the support rod. The axial distance of the upper end is recorded as L, the axial distance from the rotating part to the lower end of the reversing door is recorded as K, and the vertical distance from the rotating part to the bottom of the pipe is recorded as H, then L>K>H, the lower end of the reversing door and the support rod are located On the same side of the connecting column, both sides of the upper end of the reversing door are respectively connected to the upper ends of the connecting columns on both sides through two limit ropes. When the limit rope is tight, the level of the upper end of the reversing door is not lower than the level of the support bar.

The principle of the utility model is: firstly extend the device into the drainage pipe through the support rod, and make the lower end of the connecting column contact with the bottom of the pipe; under normal circumstances, the water level in the drainage pipe is relatively low. The point of action of the equivalent force of the water flow on the reversing door is roughly located on the surface of the reversing door below the rotating part. At this time, the lower end of the reversing door is pressed against the bottom of the pipe under the action of the water flow, so that the water flow is blocked. stagnation, this process is called the water storage process; after the water storage process starts, the water level begins to rise gradually, and the height of the action point of the equivalent force also gradually rises, when the height of the action point rises above the rotating part After a certain height, the reversing door will be pried under the force of the water flow and flipped outwards. At this time, a large amount of accumulated sewage will gushes out from the bottom of the reversing door. The ability is also significantly enhanced, so that the downstream silt is washed away. This process is called the dredging process; during the dredging process, due to the restriction of the limit rope, the flip door has a limited flip angle and will not overturn; dredging After the process is over, due to the drop of the water level, the height of the point of action of the equivalent force returns to the bottom of the rotating part, and the reversing door is reset under the force of the water flow, and the next round of water storage process is restarted; the structure of the utility model It is simple and easy to operate. The cleaning device can be placed in the pipeline through the hoisting device, without the need for personnel to go down the well. The desilting process is automatically carried out with sewage, and the cost is low. It is especially suitable for the daily maintenance of drainage pipelines.

Preferably, the support rod is a multi-stage telescopic structure with adjustable length. During the dredging process, the position of the device can be adjusted through the multi-stage telescopic structure to expand the desilting range of the device.

The beneficial technical effect of the utility model is: the structure is simple, the operation is convenient, and the kinetic energy of the sewage itself is used to realize the dredging operation.
