RU2515231C1 - Device to remove dirt from irrigating channels - Google Patents

Abstract

FIELD: construction.

SUBSTANCE: device includes an elastic cloth installed across the flow. The elastic cloth is made as meshed according to shape and size of the flow and is fixed to the frame. The frame is installed on a rotary crosspiece, which has a drive. At the same time the frame comprises a rotary axis parallel to the direction of the flow with the possibility of frame rotation with the elastic cloth perpendicularly to the direction of the flow and fixation of the frame in the necessary position. At the side part of the crosspiece there is a loading cart for removal of dirt.

EFFECT: increased quality of irrigating water treatment, simplified design and reduced energy intensity of treatment.

Description

The invention relates to hydraulic structures and can be used to remove pollution from the channel of irrigation canals.

A known method of cleaning canals, including cutting tree-shrubbery and weed vegetation along the berms and slopes of irrigation canals, removing cut vegetation and treating stumps and stubble after cutting, while before processing the stumps of bushes and stubble weed vegetation, removing cut vegetation from berm and slopes is carried out by hydraulic washing to the bottom of the canal, stumps and stubble are milled to the minimum permissible height, the crushed fraction, sludge, mineral and other litter are washed to the bottom of the canal, the water level in the cana is raised len to 1/4 ... 1/3 of its height and discarded, large fractions are removed from the surface of the barrier gratings, and small fractions are captured by wire mesh (RU, patent for the invention No. 2270290 C1, IPC ЕВВ 3/02, ЕОВВ 15/00).

The disadvantages of this method include the complexity of execution, low quality of water purification, flushing of contaminants to the bottom of the channel, the possibility of destruction of slopes during hydraulic washing.

A known method of cleaning canals, including cutting tree-shrubbery and weed vegetation along the berms and slopes of irrigation canals, removing cut vegetation and processing stumps and stubble after cutting, while before processing stumps of tree-shrubbery and stubble weed vegetation, removing cut vegetation from berm and slopes produced by hydraulic washing to the bottom of the canal, stumps and stubble are milled with a height of 4 ... 6 cm, the crushed fraction, sludge, mineral and other litter are washed off to the bottom of the canal, the water level in the can le raised to 1 / 4-1 / 3 and discharge channel height, large fraction recovered from the surface of protective gratings and fines trapped cellular grids (RU, patent №2280127 C2, IPC E02V 3/02).

The disadvantages of this method include the complexity of execution, poor quality of water treatment, the possibility of destruction of slopes during hydraulic washing, repetition of operations, increased energy intensity.

A device for cleaning sediment from riverbeds and canals, comprising a drive, a hydraulic sediment cultivator and a mechanism for moving it, the drive is made of at least one water wheel with a pump supplying water to the sediment washing line, with a shaft connected to it a transmission mechanism mounted on the shaft of the water wheel, and the mechanism for moving the hydraulic sediment cultivator is equipped with a movable frame with two stops mounted on a support, a fixed frame with two stops and a plate mounted on the axis in the movable frame and alternately resting on the stops of the movable and fixed frames for moving the hydraulic sediment cultivator according to the type of fish tail (RU, patent for invention No. 2395640 C1, IPC EV 3/02).

The disadvantages of this device include design complexity, poor quality of water treatment, significant energy consumption.

A control device is known that includes an elastic panel installed across the flow, the upper edge of which is attached to the float, and the lower edge does not reach the bottom and is equipped with weights attached to the floating means, while the float is attached to the carrier cable using guy wires, both ends of which are connected to a floating vehicle, while the goods are also connected by cables to the floating vehicle (RU, patent for invention No. 2291930 C1, IPC EV 3/02).

The disadvantages of this device include the inability to unload the collected sediment in the transportation of the removal agent, a significant increase in hydraulic resistance in the channel, the inability to capture contaminants along the entire cross section of the channel and their uniform distribution over the sheet.

This regulatory device is accepted by us as the closest analogue.

The problem to which the invention is directed is to improve the quality of irrigation water treatment, simplify the design, reduce the energy consumption of treatment.

The technical result - improving the quality of irrigation water treatment and the reliability of irrigation machines.

The specified technical result is achieved in that the device for removing contaminants from the irrigation canals, including an elastic cloth installed across the flow, according to the invention, the elastic cloth is mesh in shape and size of the flow and is fixed to the carcass mounted on a rotatable crosspiece with a drive, while the carcass has rotary axis parallel to the flow direction with the possibility of rotation of the frame with an elastic panel perpendicular to the direction of flow and fixing the frame in the required In this position, a shipping trolley is provided at the side of the cross to remove contaminants.

An analysis of the prior art by the Applicant, including a search by patent and scientific and technical sources of information and identification of sources containing information about analogues of the claimed invention, allowed to establish that the Applicant did not find an analogue characterized by all the features of the claimed invention. Therefore, the claimed invention meets the requirement of "Novelty" under applicable law.

The invention is illustrated by drawings.

Figure 1 shows a device for removing contaminants from irrigation canals, side view.

Figure 2 is the same, top view.

Figure 3 is the same, side view with a raised panel.

Figure 4 is the same, front view in the process of removing contaminants from the panel.

Information confirming the possibility of implementing the claimed invention are as follows.

A device for removing contaminants from the irrigation canals is installed on the banks of the 1 irrigation canal and includes a rotary cross 2 mounted on the axis 3. Rotary axes 4 are made perpendicular to the axis 3, making it possible to rotate the frame 5 with the elastic panel 6 perpendicular to the flow direction. On the opposite bank, the frame 5 rests on the latches 7. For the drive of the rotary cross 2 and the frame 5, a drive device 8 is provided. A shipping trolley 9 is provided at the side of the cross 2.

A device for removing contaminants from irrigation canals is fixed to the shores of channel 1 and has the ability to rotate on axis 3.

When the carcass 5 is lowered into the channel, the contaminants are held by a mesh cloth 6 and purified irrigation water enters the water intake.

As soon as the amount of impurities begins to cause resistance to flow, the drive of turning the crosspiece 2 is turned on and the contaminated cloth 6 leaves the flow and the frame 5 is installed in a horizontal position. Purification from contamination will be carried out by the following frame with a clean cloth 6.

Raised in a horizontal position, the frame 5 is rotated in a vertical position and at an angle necessary to remove contaminants from the panel 6 (figure 4). Contaminants are loaded into the cart 9 and removed for use on fertilizers.

The use of a rotary frame with a mesh cloth mounted on the crosspiece provides improved quality of irrigation water treatment, simplifies the design and reduces the energy consumption of cleaning.
