Description

[Detailed description of the invention] "Industrial field of application" This invention relates to a continuous pipe cleaning system that can reliably clean drainage boreholes in water collection wells and pipes with a length of about 50 m. It is.

``Conventional technology and its problems'' In general, a water collection well is connected to a number of pipes for collecting underground water. Traditionally, devices for cleaning this type of pipe include inserting a small-diameter pipe into the cleaning pipe hole and washing out the deposits on the pipe with air or water, or using a boring machine to connect the thin pipes. while inserting the
It is generally known that a brush or the like is attached to the tip and cleaning is carried out using distilled water (for example, techniques shown in Japanese Utility Model Application Publication No. 50-128191 and Japanese Patent Application Laid-open No. 47-21964).

However, since steel pipes leading to water collection wells are easily infested with fibrous materials such as roots of water, the force of the air or jet water only partially cuts off the fibrous materials, making it impossible to remove the entire pipe. This cannot be done with brush-based devices.
There was a drawback that the brush became tangled with fibers, making it impossible to completely clean the pipe.

"Means for Solving the Problems" This invention was made in view of the above circumstances, and provides a continuous pipe cleaning system that can completely remove limescale, earth and sand, roots of water, etc. In order to achieve this purpose, a rotor C is provided at the tip of the guide pipe B and rotates around the axis of the guide pipe B.
A wire brush E is provided on the rotor C and rotates integrally with the rotor C to scrape off deposits inside the pipe F. At a rear position of the wire brush E, the rotation radius of the wire brush E is The surface along the length direction is formed in a semicircular arc shape curving forward, and rotates together with the rotor C to remove deposits or fibers inside the pipe F. A thin cutter D is provided for cutting, and a jet hole 7 is provided on the outer surface of the rotor C and at the rear of the cutter D, and jets out high-pressure water to apply rotational force to the rotor C. I have to.

``Operation'' According to this invention, the wire brush E and the cutter D rotate in the same direction together with the rotor C by the reaction force of high-pressure water jetted from the jet hole 7.

Moreover, since the rotation radius of the wire brush E and the cutter D are formed to be approximately the same, when inserted into the pipe F which is slightly smaller than the rotation radius, the wire brush E and the cutter D are formed inside the pipe F. It slides on the wall surface to remove deposits or fibers such as dirt, limescale, water roots, etc. that have adhered to the inside of the pipe F. In this case, in particular, the wire brush E located at the front mainly scrapes off deposits such as dirt, limescale, etc., and then the cutter D located at the rear scrapes off the inside of the pipe F with the wire brush E. Cut fibrous materials such as aquatic roots that cannot be removed.

In addition, since the cutter D is formed in a semicircular arc shape curving forward and is thin, it has good adhesion to the inner wall of the pipe, and in this respect, it is also useful for cleaning the pipe. You can complete your work.

In addition, the longitudinal surface of the cutter D is formed into a semicircular arc shape that curves forward, and the jet hole 7 for spouting high-pressure water is provided at the rear of the cutter D. Even if fibers such as water roots become entangled with the cutter D, the high-pressure water jetting out from behind pushes the fibers forward and prevents them from adhering to the cutter D.

In addition, since the cutter D is installed behind the wire brush E, even if there is a solid object such as a stone or sand in front of the wire brush E, the wire brush E acts as a cushioning material to prevent the cutter D located at the rear. This prevents the blade from being damaged.

"Embodiment" An embodiment of the present invention will be described with reference to FIGS. 1 to 3.

In these figures, symbol A is a high-pressure polypipe connected to a high-pressure water source (not shown). By using a long high-pressure polypipe A, it is designed to be continuously inserted into the tube (pipe) indicated by the symbol F, and the inner conduit A ₁ is supplied by a high pressure water source.
High-pressure water of 40 to 50 kg/cm ² is now being distributed.

A tapered joint 1 is provided at the tip of the high-pressure poly pipe A, and the tapered joint 1
A guide pipe B is detachably attached to the guide pipe B by a screw 1a. When this guide pipe B is attached to the high-pressure polypipe A through the tapered joint 1, the pipe line _B1 is connected to the pipe line _A1 of the high-pressure polypipe A.

Further, on the outer peripheral surface of the guide pipe B, a vane plate 2a and a vane plate 2b are arranged at intervals in the length direction. The blade plates 2a and 2b are arranged so as to protrude outward in the radial direction, respectively, and when inserted into the pipe F, a guide pipe B, a rotor C, a cutter D, which will be described later, The wire brush E is positioned at the center of the tube F.

At the tip of the guide pipe B, a rotor C that rotates around the axis of the pipe B is provided. The rotor C has an internal conduit _C1 connected to a conduit _B1 of a guide pipe B, and a ball bearing 4, which is held between washers 3 and 5, is provided between the rotor C and the guide pipe B. The ball bearing 4 functions to smooth rotation against water pressure and at the same time prevent water leakage.

An impeller 6 is provided in the conduit _C1 of the rotor C. This impeller 6 has pipes A ₁ ,
When high-pressure water is sent through B ₁ and C ₁ , the resistance causes the rotor C to rotate along the axis of the guide pipe B.

Further, the outer peripheral surface of the rotor C is provided with a jet hole 7 connected to the conduit _C1 . This jet hole 7 is designed to generate rotation in the rotor C similarly to the impeller 6 by jetting out high-pressure water along the circumferential direction inside the pipe F. The water spouted from the jet hole 7 causes wire brush E and cutter D to be described later.
It is designed to wash away the deposits on the pipe F that have been scraped off to the outside.

At the tip of the rotor C, the guide pipe B
A support rod 8 is provided along the axial direction of the support rod 8, and the tip and base ends of the support rod 8 are free from limescale, earth and sand, etc.
A wire brush E and a cutter D for removing water roots are respectively fixed.

The wire brush E rotates together with the rotor C to primarily scrape off deposits (small in particle size and hard) such as dirt, limescale, etc., and can also be scraped off by the wire brush. It is designed to cut (long and soft) fibers such as dead aquatic roots.

The cutter D is formed in a semicircular arc shape with the surface along the length direction curved forward, and is formed in a thin shape, and has the same rotation radius as the wire brush E. There is.

The reason why the cutter D is shaped like a semicircular arc curved forward is that when the cutter D is inserted into a pipe F having a diameter slightly smaller than the rotation radius of the cutter D, the tip of the cutter D can be inserted into the pipe F. This is to allow it to slide in close contact with the inner wall of F.

On the other hand, a support rod 8 that supports the wire brush E
The tip end is a ball joint 9.

In the continuous pipe cleaning system configured as described above, 40

Remove limescale, sediment, water roots, etc. As a result, the continuous pipe cleaning system described above has the following effects.

(b) Wire brush E and cutter D scrape off dirt, limescale, water roots, etc. adhering to the inside of pipe F. At this time, the wire brush E located at the front mainly scrapes off deposits such as dirt, limescale, etc., and then the cutter D located at the rear removes the aquatic roots that could not be scraped off by the wire brush E. Clean the pipe F completely by cutting the fibers such as.

(b) Since the cutter D is formed in a semicircular arc shape that curves forward and is formed in a thin shape, when the cutter D is inserted into a pipe F having a diameter slightly smaller than the rotation radius of the cutter D, , the adhesion to the inner wall of the pipe F is improved, and in this respect as well, the pipe F
cleaning work can be completed.

(c) Since the cutter D is provided at the rear of the wire brush E, even if there is a solid object such as a stone or sand in front, the wire brush acts as a shield and the blade of the cutter located at the rear is protected. Direct injury is prevented.

(d) The cutter D is formed into a semicircular arc shape that is curved forward, and the jet hole 7 for spouting high-pressure water is provided at the rear of the cutter D.
Even if fibrous materials such as water roots become entangled in the vine, the high-pressure water jetting from the rear will push the fibrous materials forward and prevent them from adhering to the vine.

(e) The water spouted from the jet hole 7 of the rotor C washes away the deposits that have been scraped off. At this time, the water ejected from the jet hole 7 is directly sprayed onto the inner surface of the pipe F, so that the deposits removed by the wire brush E and the cutter D can be reliably discharged to the outside.

(f) Since the rotor C is rotated by the water supplied by the high-pressure polypipe A, a driving device such as a motor for driving the rotor C is not required.
That is, the high-pressure water serves both to discharge the deposits to the outside and to rotate the wire brush E, cutter D, etc.

(G) It is sufficient to run the high-pressure polyethylene pipe A connected to a high-pressure water source to the entrance of the pipe F into which the wire brush E etc. is inserted, and this makes it possible to work in places such as inside wells where there is a limited working space. Even so, it can be adequately dealt with.

(H) High-pressure water (40-50Kg/cm ² ) in high-pressure polypipe A
When flowing, the hardness of the hard polypipe A increases, so that an operator can push the wire brush E and cutter D into the pipe F while holding the high-pressure polypipe A with his hand. At this time, the state of adhesion of dirt, etc. inside the pipe F can be determined by the resistance when the high-pressure poly pipe A is pushed in, and the cleaning work is completed by reciprocating the parts with particularly high resistance many times. Can be done.

(li) By using a long high-pressure polypipe A, the pipe A can be continuously inserted into the pipe F, improving work efficiency compared to the conventional pipe adding type. It is possible to improve the

(nu) The rotor is rotated by the vane plate 2 of guide pipe B.
Since it rotates at the center of the tube F, scratches on the tube F can be minimized.

In addition, if the inside of the pipe F is strongly clogged with deposits, it is sufficient to remove the pin of the ball joint 9 and rotate it only with the cutter D. Further, the cutter D and the cleaning wire brush E may be easily replaced.

"Effects of the invention" As explained in detail above, according to this invention, the cutter D is provided at the rear of the wire brush E, so that the wire brush E located at the front removes dirt, limescale, etc. inside the pipe F. The kimono is mainly scraped off, and then the cutter D located at the rear cuts off fibrous materials such as water roots that cannot be scraped off by the wire brush E.

In addition, the cutter D is formed in a semicircular arc shape that curves toward the front and is formed in a thin shape, so that when inserted into the pipe F having a diameter slightly smaller than the rotation radius of the cutter D, Adhesion to the inner wall of the pipe F is improved, and the cutter D described above can efficiently cut fibers.

Further, the surface along the length direction of the cutter D is formed in a semicircular arc shape curving toward the front, and a jet hole 7 for spouting high-pressure water is provided on the outer surface of the rotor C and at the rear position of the cutter D. Therefore, even if fibrous materials such as aquatic roots become entangled with this cutter D, the high-pressure water jetting from the rear will push this fibrous material forward and prevent it from adhering to the cutter D. Ru.

Furthermore, since the cutter D is provided at the rear of the wire brush E, even if there is a solid object such as a stone or sand in front, the wire brush E located at the front acts as a buffer and the wire brush E is placed at the rear. This prevents the blade of the cutter D from being directly damaged.

Therefore, according to the present invention, fibrous materials such as water roots that appear in special places such as drainage boreholes of so-called water collection wells that collect spring water underground in one place protect the vine from impact. This has the effect that the pipe F can be efficiently cut and removed, and the pipe F can be completely cleaned.
