Description

Temporary plugging device for broken hole of water conservancy irrigation water delivery pipeline

Technical Field

The utility model relates to a broken hole shutoff technical field of pipeline, especially a temporary plugging device in broken hole of irrigation conduit.

Background

There are multiple kinds of irrigation raceway, and wherein high-pressure hose carries out the conduit temporarily, because its is coiled and is accomodate the convenience to can carry out nimble adjustment according to the on-the-spot needs, so by wide application. However, the hose has obvious defects in use, such as dragging on the ground when being laid or coiled, being easily scratched by sharp gravel to cause a broken hole, being not easy to be found under the condition of no water supply, and generating water leakage or spraying at the broken hole after water supply.

The publication CN210510731U discloses a device for repairing a broken hole of a pipeline, which is to place a leakage blocking plate in the broken hole, and then tighten the leakage blocking plate by using a screw and cling to the inner wall of the pipeline to realize the blocking. However, in practical application, the scheme has three obvious defects: firstly, the scheme is only suitable for hard pipes made of hard materials and is not suitable for flexible hoses, and the leakage blocking plate cannot be attached to the inner wall of the hose due to the fact that the hose is made of the flexible materials and is easy to deform, and water can still leak; secondly, the broken holes of the hose are mostly scratched in a long strip shape, the mode in the scheme can expand or enlarge the broken holes, the plugging is not favorable, and the later maintenance is not favorable; thirdly, the scheme can only carry out plugging when no water or high pressure exists in the pipeline, if high water pressure exists in the pipeline, maintenance personnel can bear long-time water flow impact, and also can quickly and accurately tighten a plurality of screws one by one, the process is complicated and long, and the spray of water causes the clothes of the personnel to be very inconvenient to wet; fourthly, only the plugging plate performs substantial plugging in the whole process, and a larger water leakage risk still exists in the later stage.

The temporary plugging device capable of quickly plugging the crevasses is suitable for quickly plugging crevasses on a water delivery pipe in an irrigation site, can cut off the water flow of the seal in the plugging process at the first time, then fix the water flow to realize secondary thorough plugging, is convenient and quick in plugging process, and can effectively prevent the spray from wetting the clothes of maintenance personnel.

SUMMERY OF THE UTILITY MODEL

Detailed Description

The following provides a more detailed description of the present invention with reference to the accompanying drawings.

As shown in fig. 1 to 4, the utility model comprises a vertical round bar, the round bar is separated along the axial direction to form two bilaterally symmetrical swing rods 1 with semicircular cross sections, the lower ends of the two swing rods 1 are hinged, a semicircular ring 2 coaxial with the swing rods 1 is arranged outside the lower ends of the swing rods 1, the two semicircular rings 2 can form a complete circle when in the same plane, and the swing rods 1 and the semicircular rings 2 are fixed together through fixing rods; the two semicircular rings 2 are sleeved in the same elastic rubber bag 3, and when the two semicircular rings 2 form a complete circle, the elastic rubber bag 3 is stretched;

the round rod is sleeved with a cylinder 4, a pin 6 horizontally penetrates through the cylinder 4, a through hole corresponding to the pin 6 is formed in the round rod, and the pin 6 penetrates through the through hole; the outer edge surface of the round rod is sealed with the side wall of the cylinder 4; the lower extreme of drum 4 is the loudspeaker form that the opening is decurrent, and 4 lower extremes of drum have and set up platform 5, all are provided with the rubber pad on the terminal surface that semicircle board and platform 5 are close to each other, and when 6 levels of pin run through round bar, drum 4, semicircle ring 2 presss from both sides the water pipe lateral wall tightly with platform 5.

In order to prevent the semicircular ring 2 from expanding the broken hole when entering the broken hole, the fixing rod is fixed at the front end of the semicircular ring 2.

In order to prevent water from leaking between the two swing rods 1, sealing gaskets are adhered to the side walls, close to each other, of the swing rods 1, and sealing rings are arranged on the inner side walls of the cylinders 4.

In order to facilitate the insertion and the drawing of the pin 6, the left end of the pin 6 is conical, and the right end of the pin 6 is fixed with a pull ring 7.

It is worth noting that the rubber pads fixed on the semicircular ring 2 and the platform 5 are thick, so that the side wall of the pipeline can be effectively prevented from being broken, the sealing performance can be effectively improved, the plugging effect is enhanced, and the rubber pads have elasticity and can adapt to the side walls of hoses with different thicknesses. The rubber sleeve can be made of various materials, such as rubber, latex, butyronitrile and the like, is rich in elasticity and toughness, and can be attached to the inner wall of the hose under the action of water pressure in the hose.

When the device is used, the pin 6 and the cylinder 4 are detached, the two swing rods 1 are in the pattern shown in fig. 3, the rubber bag 3 is sock-shaped and is sleeved on the two semicircular rings 2, then as shown in fig. 4 (side view in use), the semicircular rings 2 firstly enter the broken holes downwards from one end, after the semicircular rings 2 completely enter the broken holes, the two swing rods 1 are combined towards the middle to form the state shown in fig. 1, the rubber bag 3 is opened at the moment, the rubber bag 3 is tightly attached to the inner wall of the hose under the action of water pressure in the hose to realize plugging, then the cylinder 4 is sleeved into the circular rod from top to bottom, when the platform 5 downwards and the semicircular rings 2 clamp the side wall of the hose together, the through hole on the circular rod is just positioned at the inserting position of the pin 6 on the cylinder 4, and the pin 6 is inserted into the circular rod from right to left at the moment, so far, secondary plugging is also completed between the platform 5 and the outer side wall of the hose.

There are two-layer shutoff effect in this scheme, one of them is the shutoff that forms is hugged closely with the hose inner wall under intraductal water pressure effect to rubber bag 3, and its second, the shutoff between platform 5 and the hose lateral wall. Therefore, even if the rubber bag 3 is broken under the action of water pressure, the spraying phenomenon can not occur, the temporary treatment requirement on the site can be met, and the irrigation can be thoroughly repaired after the completion.

According to the scheme, rapid plugging can be performed in the process of water delivery in the pipe, the broken hole can be plugged by the rubber bag 3 at the first time, and clothes of maintenance personnel are effectively prevented from being wetted; the quick dismantling device can also be quickly dismantled without enlarging the crevasses during dismantling.

The lower end of the cylinder 4 in the scheme is arranged to be horn-shaped, so that the two swing rods can be better and more conveniently inserted into the cylinder 4.
