Detailed Description
Aiming at the defects of the prior art, the invention solves the problem that a plurality of inclined plane metal brushes connected in series are utilized to clean the pipeline in a traction mode so as to realize better pipeline cleaning effect and reduce the structural complexity. Specifically, the traction type cleaning device for the water supply and drainage pipeline comprises a plurality of pipe brush groups with different sizes and traction equipment for providing traction force for the pipe brush groups; the pipe brush group consists of a plurality of identical pipe brushes which are formed by connecting a movable connecting piece and a cable in series; the pipe brush comprises a disc-shaped brush disc and metal brushes uniformly arranged on the circumference of the brush disc, wherein the brush face of each metal brush is inclined towards the other face from one face of the brush disc where the metal brush is located.
The inclination angle of the brush surface of the metal brush is closely related to the traction force and the cleaning effect, and a large number of experiments show that when the inclination direction of the brush surface and the axial direction of the brush disk form an included angle of 20-40 degrees, the best cleaning effect can be obtained and the required traction force is moderate.
The metal brush can be made of iron wire brushes, steel wire brushes and the like, preferably martensitic stainless steel wires, and is high in elastic modulus and not easy to deform and bend. In order to make the metal brush more firm and reduce the manufacturing difficulty, it is preferable to adopt a mode of asymmetrically bending a cluster of metal wires to prepare the metal brush, that is, the metal brush is a cluster of metal wires which penetrates through the edge of the brush disk (through a preset through hole) and is asymmetrically bent towards the circumferential direction of the brush disk (one side of the metal brush extends out of the hole and has a slightly longer length, and the other side of the metal brush is slightly shorter); in order to prevent the metal brush from being loosened easily during the cleaning process, the lower part of the end face of the metal brush can be further fastened by using a lantern ring.
The number of the tube brushes in the tube brush group can be increased or decreased according to actual needs, and 3 tube brushes are preferably adopted to form the tube brush group.
When a general pipe brush moves on the inner wall of a pipe wall, because scales in the pipe wall are usually extremely uneven, the pipe brush is easy to incline when moving in the pipe before cleaning (in a scaling state), and the pipe wall cannot be forced, so that poor cleaning is caused; the invention adopts a linkage mode of a plurality of tube brushes connected in series by movable connecting pieces and cables to well solve the problem, when the inner part of the tube wall moves before cleaning, the tube brushes in the tube brush group are usually not on a straight line, if one tube brush is in an inclined state, the other two tube brushes can quickly right the inclined tube brush due to the movable connecting pieces, thus the normal cleaning state can be quickly recovered.
When the cleaning device is used for cleaning the pipeline, a group of pipe brush groups with corresponding sizes are selected according to the inner diameter and the scaling condition of the pipeline to be cleaned, the selected pipe brush groups are sequentially pulled from one end of the pipeline to be cleaned to the other end according to the order from small to large in size, the direction of traction force is always kept to point from the higher side of the brush surface of the metal brush to the lower side of the brush surface in the traction process, and whether the pipe brush group with the larger size needs to be replaced is judged according to whether the traction force is smaller than a preset traction force threshold value or not; and finally, dragging the pipe for many times by using a dumbbell-shaped plunger in the pipe until no scale is brought out, and finishing the pipe cleaning process.
After cleaning, the pipeline can be repaired by adopting various existing repair technologies.
To facilitate understanding of the public, the technical solution of the present invention is further described in detail by a preferred embodiment in conjunction with the accompanying drawings:
as shown in fig. 1 and 2, the tube brush set of the present embodiment is formed by connecting 3 identical tube brushes 1 in series, and adjacent tube brushes 1 are connected with each other through a movable connecting piece 2 and a cable.
As shown in fig. 3, the tube brush 1 includes a disk-shaped brush disk 10 and a series of metal brushes 11 uniformly arranged on the circumference of the brush disk 10, the brush surface of the metal brush 11 is inclined from one surface of the brush disk 10 to the other surface, and the inclination directions of the metal brush surfaces of 3 tube brushes 10 are the same. In this embodiment, the metal brush 11 is a cluster of martensitic stainless steel wires which penetrates through the edge of the brush disk 10 (through a predetermined through hole) and is bent towards the circumferential direction of the brush disk 10 asymmetrically (one side is slightly longer than the length of the hole, and the other side is slightly shorter), and in order to prevent the metal brush from loosening easily during the cleaning process, the lower part of the end face of the metal brush 11 can be further fastened by using a collar.
As shown in fig. 2 and 3, in order to enhance the maximum traction force that can be borne by the brush plate, in this embodiment, the brush plate 10 is a unitary forged piece, and the central area thereof is thickened, i.e. the thickness of the central area of the brush plate 10 is greater than that of the peripheral area.
As shown in fig. 3, the central positions of both sides of the brush plate 10 are provided with connecting parts for connecting the movable connecting pieces, and the connecting parts include anchoring pieces 12 and swivel rings 13; the anchoring member 12 is fixedly disposed at the center of both sides of the brush plate 10, and the swivel 13 movably passes through a through hole disposed at the top of the anchoring member 12.
As shown in fig. 4 and 5, the movable connecting member 2 in this embodiment includes two U-shaped shackles 20 having a plane bottom surface and through holes formed on the bottom surface, the bottom surfaces of the two U-shaped shackles 20 are connected by longitudinal pins 21 penetrating through the through holes on the two bottom surfaces, and a transverse pin 22 of one of the U-shaped shackles passes through the swivel 13, thereby achieving a movable connection with the swivel 13; the other shackle is then connected to a cable, preferably using an anchor chain as the cable, by simply passing the transverse pin 22 of the other shackle through the end link of said anchor chain.
Through the movable connecting structure, on one hand, the three pipe brushes can work normally when not moving on the same straight line, and the tension transmission of the steel cable is not influenced; on the other hand, when one or two of three brush pipes was in the tilt state because the scale deposit is inhomogeneous, under the effect of such swing joint structure, along with the effect of traction force, the brush pipe can resume normal upright state work very fast, the leading principle is exactly under traction force, the atress is concentrated the point on the top of swivel 13, and in case the horizontal pin 22 of U type shackle slides to swivel 13 top, the brush pipe must be in upright state to it is efficient when the action is washd to make the brush pipe can carry out in the pipe wall, and the cleaning performance is good moreover.
When the device is used for cleaning the water supply and drainage pipeline, the following steps can be specifically adopted:
firstly, detecting the determined pipeline needing to be cleaned by adopting a CCTV (closed circuit television) endoscope, and determining whether the cleaning method is adopted or not according to the severity of scaling, wherein the cleaning method is particularly suitable for the seriously-scaled pipeline with the unilateral scaling thickness exceeding 50 mm;
digging operation pits at two ends of a pipeline to be cleaned, and manually cutting short pipes with the length of 0.75-2 m at the two ends of the pipeline so as to carry out cleaning operation;
