The method of collection and removal of debris from the channel or pressure conduit and device for its implementation
(57) Abstract:The invention relates to hydraulic engineering, namely structures, providing water purification from Sora in the channels, culvert and diversion devices. The method consists in the fact that in the initial position of the canal or penstock overlap litter retaining mechanism comprising at least two pivotally connected sections, arranged one above the other and having the ability to rotate the joints in the vertical plane. After accumulation of rubbish mechanism withheld litter with a lever to raise the bottom end of the lower section to the surface, free from litter, and then lowered by releasing the traction. The mechanism is moved in the guide grooves, and its sections perform lattice. In the first phase of the ascent carry out the seizure and retention of litter by folding sections of the mechanism, in the last recovery phase discharge Sora through the rotation mechanism on the top of the lift with simultaneous hollow opening mechanism. After reset Sora when lowering mechanism by releasing thrust under their own weight mechanism carried out sequentially reverse the turn, folding, descent, rastu disclosure between the sections at an angle of 180oin the lower operating position and an upper position, removal of litter and with the possibility of closing to 0oduring the ascent and descent. In the upper and lower parts of the guide grooves are stops to stop the ascent and descent mechanism. Litter retaining mechanism is made with a center of gravity offset from its reference points towards the flow. The invention allows to collect litter from depths exceeding amount of litter retaining mechanism, rise to the surface and remove it without the use of additional devices. 2 S. and 1 C.p. f-crystals, 5 Il. The invention relates to hydraulic engineering, namely structures, providing water purification from Sora in the channels, culvert and diversion devices.The known method of collection and removal of litter from the water and device for its implementation at the request of Japan 07233516. In the channel towards the flow install litter retaining mechanism, consisting of the front along the stream and rear sections which are connected pivotally with the possibility of rotation relative to each other in the vertical plane. Front along the stream edge of the front section hinged clip on the bottom of the channel also can be rotated in the hinge in poverhnosti channel, and has the ability to move along the guides with roller on the horizontal axis. In the initial operating position of the zone of connection of the sections is in the lowest position so that the front along the flow section is located at the bottom of the channel is almost in a horizontal position, and back along the stream section overlaps the channel, ensuring the collection of litter. After filling mechanism litter the area of the connection sections is moved upwards by means of traction, working on the lifting mechanism. In the raised position, the front section overlaps the canal, with the raised rear section of the produce destruction of Sora using hand tools. As described above, and using such a device it is impossible to collect rubbish from great depths (depths exceeding the size of trash mechanism) and raise it to the surface.Known Japan's bid 08144244 A2, which outlines the method and the device are similar to the above, but remove litter produced by setting opposite the raised surface of the upper section closed tape mechanism, on which is mounted a scraper.The method described in the application Japan 08144244 A2, and using the stated device can collect the rubbish from the pain which also requires the use of additional devices for the removal of rubbish.Closest to the claimed is the method and the device according to the patent of the Russian Federation 2023791, selected as a prototype, in which the watercourse install litter retaining mechanism attached to the upper edge of the supporting element and the bottom edge of the flexible rods connected with the lifting mechanism. Litter retaining mechanism made in the form of waterproof plate mounted to rotate about an axis to the bottom edge of the plate on the hinge is attached to the flap at a distance from the flap perpendicular to the plate installed wall. After accumulation of litter lift the flap by means of rods, turning it into the hinges, continue lifting the flap, turning the device around an axis attached to a supporting element. COP caught in the tray formed by the flap plate and wall wash off the flow of water supplied by a pump. The method does not allow to collect rubbish from the depths, exceeding the size of the litter retaining mechanism and raise it to the surface. The method does not allow to remove the litter from the litter retaining mechanism without the use of additional devices.The technical result of the proposed method of collection and removal of debris from the channel of the bin, exceeding the size of the litter retaining mechanism, lifting it to the surface and removal without the use of additional devices (special resetlasterror machine).To solve this problem and achieve the specified result of the proposed method of collection and removal of debris from the channel or pressure conduit, namely, that in the initial position of the canal or penstock overlap litter retaining mechanism comprising at least two pivotally connected sections, arranged one above the other and having the ability to rotate the joints in the vertical plane, after the accumulation of litter mechanism withheld litter with a lever to raise the bottom end of the lower section to the surface, free from litter, and then lowered by releasing the traction, which mechanism do with the ability to move in the guide grooves, and a mechanism section perform lattice, in the first phase of the ascent carry out the seizure and retention of litter by folding sections of the mechanism, in the last recovery phase discharge Sora through the rotation mechanism on the top of the lift with simultaneous full disclosure mechanism, and after the reset Sora when SDA is Ino reverse the spread folding, descent, erection and installation of the mechanism to its original position.To achieve the above result, it is proposed litter retaining device for a channel or pressure conduit, comprising a fixed litter retaining mechanism containing at least two upper and lower pivotally United sections, overlapping the channel and having the ability to rotate the joints in the vertical plane, and the lower section are connected by rods with a lifting mechanism, and the upper top edge pivotally attached to the axis, and the device is equipped with guide slots for lifting litter retaining mechanism, which moves the upper section, the upper and lower edge parts have placed in the slots of the wheel pairs, the sections of litter retaining mechanism is in the form of gratings, litter retaining mechanism configured to disclosure between the sections at an angle of 180oin the lower operating position and an upper position, removal of litter and with the possibility of closing to 0oduring the ascent and descent, the upper and lower parts of the guide grooves are stops to stop the ascent and descent mechanism, the guide grooves are made with the possibility of zaderjivaysia mechanism is made with the center of gravity, shifted relative to their reference points towards the stream.To improve the performance of the device the upper edge of the upper section provided with a lock, and in the upper part of the guide grooves is made corresponding to the latch stop for fixing litter retaining mechanism in the upper expanded position.The claimed invention can be implemented using the device depicted in Fig.1 and 2. In Fig.2 shows a top view of litter retaining mechanism in operating position.In Fig.1 shows:
(a) initial operating position of the collection Sora,
b) capture Sora and initial recovery phase,
C) provision of litter retaining device at the top of the rise, the same position the mechanism is in the initial phase of descent,

15 is a Playground for the dumped rubbish.Working original position (Fig.1A) sections 1 and 2 litter retaining mechanism, which is made in the form of lattices, deployed relative to each other and overlap the section of the flow, and the lower section connected to the support element 12. After accumulation of litter produce lift mechanism using a flexible rod, for example of a cable 10, through the pulley lifting mechanism 9. While in the initial recovery phase (Fig.1B) section formed through the rotation of the lower section 2 around the axis of the swivel, capturing and holding accumulated on the grill Sora. When further sampling tether mechanism in the folded position is moved upward (Fig.1B) due to the fact that the upper section fitted with wheel pairs 4 and 5, is moved along the guide grooves 13. When the upper wheel by a pair of stops 8 further sampling of the rope causes the folded grill to turn around the axis of the upper pair of wheels and at the same time to open up, releasing accumulated on the grid SOR (Fig. 1G). Fixing the grid in the upper position occurs due to the locking mechanism 6 for the stop 7. In the upper position polozhenie under its own gravity, and are above the rest, with the top edge of the upper section, located in interlocking engagement, recorded at the location of the stop 7.After removal of litter from the surface of the grating to produce the descent of the lattice. When releasing the traction - rope 10 due to the displacement of the center of gravity of the mechanism relative to the point of focusing lattice begins to turn about the axis of the upper pair of wheels 4 and simultaneously to form a relatively swivel top and bottom section 3. After the release of the locking mechanism 6 with the stop 7 folded mechanism along the guide grooves 13 is lowered into the lower position. When reaching the bottom a pair of wheels supporting the platform 14 (Fig.1B), the upper section 1 is stopped, and the lower section 2 begins to unfold relative to the hinge connection of the upper and lower sections 3 and rests on the supporting elements 12, occupying the original position (Fig.1A).The inventive method for collection and removal of debris from the channel or pressure conduit differs from traditional so that you can collect the rubbish at great depths (exceeding the size of trash mechanism), to raise it to the surface and release mechanism from Sora no additional mechanisms.
