Description

Technical Field

[0001] The present invention relates to the technical field of water conservancy projects, and particularly to a water stop device for the joints of a water conservancy aqueduct indirectly. Background Art

[0002] An aqueduct refers to an overhead water trough for conveying the water flow in a channel across rivers, streams, valleys, and roads. It is commonly used for irrigation water conveyance and also for flood discharge, sediment discharge, etc. Large aqueducts can also be navigable. Aqueducts are mainly built with materials such as masonry, concrete, and reinforced concrete.

[0003] The existing water stop devices for the joints of aqueducts are installed for water stop on the inner wall or the outer wall of the aqueduct joints. When installed on the inner wall of the aqueduct joints, the device will be continuously stressed by the long-term scouring of the water flow, resulting in a reduction in the water stop effect. And when the device is installed on the inner wall of the aqueduct joints, sediment carried in the water flow will accumulate, thus hindering the water flow and affecting the water flow conveyance. The water stop device installed on the outer wall of the aqueduct joints has a poor water stop effect, and the water flow is easily infiltrated between the aqueduct joints, affecting the water stop effect.

[0004] In view of the above problems, the present invention provides a water stop device for the joints of a water conservancy aqueduct indirectly to solve the above problems. Summary of the Invention

[0018] Further, preferably, the outer bladder is connected to an external air injection device by a pipeline, the pipeline penetrates through the connecting plate, and when the outer bladder expands, the outer elastic plate has a tendency to deflect away from the aqueduct.

[0019] Further, preferably, the inner water stop assembly includes:

The two aqueducts can also be made to tend to approach each other through the inner fixing strip and the outer fixing strip, further improving the water stop effect. Moreover, the guide vane can rotate through the water flow, thereby driving the water flow and sediment to move and preventing sediment accumulation. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION OF THE INVENTION

[0035] Referring to Figures 1 - 5 , the present invention provides a technical solution: a water stop device for an indirect joint of a water conservancy aqueduct, comprising:

[0036] The base 1, configured to be multiple, is fixed on the ground;

[0037] The aqueduct 2 is fixed on the base 1;

[0038] The water stop assemblies, configured to be multiple, are installed at the joints of the multiple aqueducts 2;

[0039] Among them, the water stop assembly includes an outer water stop assembly 3, the outer water stop assembly 3 is fixed on the outer wall of the aqueduct 2, a connecting plate 5 is detachably installed on the upper end surface of the outer water stop assembly 3, the connecting plate 5 is installed on the upper end surface of the aqueduct 2, an inner water stop assembly 4 is installed on the lower end surface of the connecting plate 5, and the inner water stop assembly 4 is located on the inner wall of the aqueduct 2.

[0040] That is to say, through the combined action of the inner water stop assembly 4 and the outer water stop assembly 3, the inside and outside of the joints between the aqueducts 2 can be synchronously water stopped, thereby improving the water stop effect.

[0041] In this embodiment, outer grooves 21 are symmetrically formed on the outer wall of the aqueduct 2, inner grooves 22 are symmetrically formed on the inner wall of the aqueduct 2, and the positions of the outer grooves 21 and the inner grooves 22 are arranged staggeredly.

[0042] That is to say, by arranging the positions of the outer grooves 21 and the inner grooves 22 staggeredly, a great influence on the wall thickness of the aqueduct 2 can be avoided.

[0043] As a preferred embodiment, the outer water stop assembly 3 includes:

[0044] Connectors 34, configured to be multiple, are all detachably installed on the connecting plate 5;

[0045] Outer elastic plates 35 are fixed on the connectors 34;

[0046] Outer fixing plates 32, configured to be two, are symmetrically fixed on the outer elastic plates 35;

[0047] Outer fixing strips 33 are fixed on the inner walls of the outer fixing plates 32 and correspond to the outer grooves 21;

[0048] Outer water stop plates 31 are fixed between the two outer fixing plates 32 and correspond to the joints of the aqueduct 2;

[0049] Outer capsules 36 are fixed between the outer elastic plates 35 and the outer water stop plates 31.

[0050] As a preferred embodiment, the outer capsules 36 are connected to an external gas injection device by pipelines, the pipelines penetrate through the connecting plate 5, and when the outer capsules 36 expand, the outer elastic plates 35 tend to shift away from the aqueduct 2.

[0051] After installation, air is injected into the outer bladder 36 through an air injection device. Then, the outer bladder 36 expands, applying pressure to the outer water stop plate 31 and the outer elastic plate 35, making the outer water stop plate 31 fit more closely to the outer wall of the joint between the flumes 2. At this time, the outer elastic plate 35 has a tendency to shift away from the flume 2. As a result, the side of the outer fixing plate 32 close to the outer elastic plate 35 has the same shifting tendency as the outer elastic plate 35, and the side away from the outer elastic plate 35 has a shifting tendency opposite to that of the outer elastic plate 35. At the same time, the two outer fixing strips 33 make the two flumes 2 tend to approach each other, improving the water stop effect.

[0052] As a preferred embodiment, the inner water stop assembly 4 includes:

[0053] Inner fixing plates 42, configured to be two, both slidably disposed on the connecting plate 5;

[0054] Inner fixing strips 43, fixed on the inner fixing plates 42 and corresponding to the inner notch 22;

[0055] Inner elastic plate 41, fixed between the two inner fixing plates 42;

[0056] Inner bladder 44, installed on the inner elastic plate 41 and located between the inner elastic plate 41 and the joint of the flume 2.

[0057] As a preferred embodiment, the inner bladder 44 is connected to an external air injection device by a pipeline. The pipeline penetrates through the connecting plate 5, and a sealing plate is fixed on the side of the inner bladder 44 close to the flume 2. When the inner bladder 44 expands, the inner elastic plate 41 has a tendency to shift away from the flume 2.

[0058] After installation, air is injected into the inner bladder 44 through an air injection device. Then, the inner bladder 44 expands, applying pressure to the inner elastic plate 41 and the sealing plate, making the inner elastic plate 41 fit more closely to the inner wall of the joint between the flumes 2. At this time, the inner elastic plate 41 has a tendency to shift away from the flume 2. As a result, the side of the inner fixing plate 42 close to the inner elastic plate 41 has the same shifting tendency as the inner elastic plate 41, and the side away from the inner elastic plate 41 has a shifting tendency opposite to that of the inner elastic plate 41. Thus, the side of the inner fixing plate 42 away from the inner elastic plate 41 fits more closely to the inner wall of the flume 2. At the same time, the two inner fixing strips 43 make the two flumes 2 tend to approach each other, improving the water stop effect.

[0059] As a preferred embodiment, the cross-section of the inner fixing plate 42 is triangular, and the cross-sections of the two inner fixing plates 42 and the inner elastic plate 41 are isosceles trapezoids.

[0060] As a preferred embodiment, a stretching shaft 51 is arranged between the connecting plate 5 and the inner elastic plate 41. One end of the stretching shaft 51 penetrates through the connecting plate 5 and is provided with threads, and a stretching nut 54 is connected to the threads. The stretching nut 54 is located on the upper end surface of the connecting plate 5. A rotating cylinder 52 is rotatably arranged on the stretching shaft 51, and a plurality of guide vanes 53 are fixed on the outer wall of the rotating cylinder 52.

[0061] Among them, after the installation is completed, the pulling of the stretching shaft 51 by the stretching nut 54 can improve the movement trend of the middle position of the inner elastic plate 41, thereby further improving the water stop effect at the position where the water flow impact is more concentrated. At the same time, the guide vanes 53 can rotate through the water flow, thereby driving the water flow and sediment to move and avoiding the accumulation of sediment.

[0062] Specifically, first, the outer water stop assembly 3 and the inner water stop assembly 4 are respectively installed on the outer notch 21 and the inner notch 22, and then the outer water stop assembly 3 and the inner water stop assembly 4 are connected through the connecting plate 5. At this time, the outer bladder 36 and the inner bladder 44 are inflated through an air injection device, so as to apply pressure in the direction of the mutual approach of the plurality of aqueducts 2, improve the water stop effect, and finally the pulling of the stretching shaft 51 by the stretching nut 54 can improve the movement trend of the middle position of the inner elastic plate 41 and further improve the water stop effect at the position where the water flow impact is more concentrated.

[0063] The above is only the preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent replacements or changes, and should be covered by the protection scope of the present invention.
