Description

Technical Field

[0001] The invention relates to the technical field of water conservancy engineering, in particular to a water-stopping device for joints between water conservancy aqueducts. Background Art

[0002] Aqueducts are overhead water channels that carry water across rivers, valleys, depressions and roads. They are commonly used for irrigation and water delivery, as well as flood and sand drainage. Large aqueducts can also be navigable. Aqueducts are mainly built with materials such as stone masonry, concrete and reinforced concrete.

[0003] The existing aqueduct joint water-stopping device is installed on the inner wall or outer wall of the aqueduct joint to stop water. When it is installed on the inner wall of the aqueduct joint, the long-term erosion of the water flow will continuously exert stress on the device, resulting in reduced water-stopping effect. Moreover, when the device is installed on the inner wall of the aqueduct joint, the silt carried in the water flow will accumulate, thereby obstructing the water flow and affecting water flow transportation. The water-stopping device installed on the outer wall of the aqueduct joint has a poor water-stopping effect, and the water flow can easily penetrate between the aqueduct joints, affecting the water-stopping effect.

[0004] In view of the above problems, the present invention provides a water-stopping device for joints between hydraulic aqueducts to solve the above problems. Summary of the invention

The internal and external fixed strips can also be used to make the two aqueducts tend to approach each other, further improving the water-stopping effect. The guide vanes can be rotated by the water flow, thereby driving the water flow and silt to move, thereby avoiding the accumulation of silt. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0035] Reference Figure 1-Figure 5 The present invention provides a technical solution: a water-stopping device for the joints between hydraulic aqueducts, comprising:

[0036] A base 1, configured as a plurality of bases, is fixed on the ground;

[0037] Aqueduct 2, fixed on the base 1;

[0038] A water-stop assembly is configured in multiple numbers and installed at the joints of multiple aqueducts 2;

[0039] Among them, the water-stop component includes an external water-stop component 3, which is fixed to the outer wall of the aqueduct 2. The upper end surface of the external water-stop component 3 is detachably installed with a connecting plate 5, and the connecting plate 5 is installed on the upper end surface of the aqueduct 2. The lower end surface of the connecting plate 5 is installed with an internal water-stop component 4, and the internal water-stop component 4 is located on the inner wall of the aqueduct 2.

[0040] That is to say, the inner and outer water-stopping components 4 and the outer water-stopping components 3 can simultaneously stop water inside and outside the joints between the aqueducts 2, thereby improving the water-stopping effect.

[0041] In this embodiment, the outer wall of the aqueduct 2 is symmetrically provided with outer notches 21 , and the inner wall of the aqueduct 2 is symmetrically provided with inner notches 22 , and the positions of the outer notches 21 and the inner notches 22 are staggered.

[0042] In other words, the staggered arrangement of the outer notches 21 and the inner notches 22 can avoid causing a significant impact on the wall thickness of the aqueduct 2 .

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

[0044] The connecting member 34 is configured as a plurality of connecting members, each of which can be detachably mounted on the connecting plate 5;

[0045] An outer elastic plate 35 is fixed on the connecting member 34;

[0046] The outer fixing plate 32 is configured as two and symmetrically fixed on the outer elastic plate 35;

[0047] An outer fixing strip 33, fixed to the inner wall of the fixing plate 32 and corresponding to the outer notch 21;

[0048] An outer water stop plate 31 is fixed between the two outer fixing plates 32 and corresponds to the joint of the aqueduct 2;

[0049] The outer bladder 36 is fixed between the outer elastic plate 35 and the outer water stop plate 31 .

[0050] As a preferred embodiment, the outer bladder 36 is connected to an external gas injection device by a pipeline, and the pipeline is arranged to penetrate the connecting plate 5. When the outer bladder 36 expands, the outer elastic plate 35 has a tendency to deviate in a direction away from the aqueduct 2.

[0051] Among them, when the installation is completed, air is injected into the outer bladder 36 through the air injection equipment, and then the outer bladder 36 expands, thereby applying pressure to the outer water stop plate 31 and the outer elastic plate 35, so that the outer water stop plate 31 is more closely attached to the outer wall of the joint between the aqueducts 2. At this time, the outer elastic plate 35 has a tendency to deviate in the direction away from the aqueduct 2, so that the side of the outer fixed plate 32 close to the outer elastic plate 35 has the same deviation trend as the outer elastic plate 35, and the side away from the outer elastic plate 35 has an opposite deviation trend to the outer elastic plate 35. At the same time, the two outer fixing strips 33 make the two aqueducts 2 tend to approach each other, thereby improving the water-stopping effect.

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

[0053] The inner fixing plates 42 are configured as two, both of which are slidably disposed on the connecting plate 5;

[0054] An inner fixing strip 43, fixed on the inner fixing plate 42 and corresponding to the inner notch 22;

[0055] An inner elastic plate 41 is fixed between the two inner fixed plates 42;

[0056] The inner capsule 42 is installed on the inner elastic plate 41 and is located between the joint of the inner elastic plate 41 and the aqueduct 2 .

[0057] As a preferred embodiment, the inner bladder 42 is connected to the external gas injection equipment by a pipeline, the pipeline is set through the connecting plate 5, and a sealing plate is fixed to the side of the inner bladder 42 close to the aqueduct 2. When the inner bladder 42 expands, the inner elastic plate 41 has a tendency to deviate in the direction away from the aqueduct 2.

[0058] Among them, when the installation is completed, air is injected into the inner bladder 42 through the air injection equipment, and then the inner bladder 42 expands, thereby applying pressure to the inner water stop plate 41 and the sealing plate, so that the inner water stop plate 41 is more closely attached to the inner wall of the joint between the aqueducts 2. At this time, the inner elastic plate 41 has a tendency to deviate in the direction away from the aqueduct 2, so that the side of the inner fixed plate 42 close to the inner elastic plate 41 has the same deflection trend as the inner elastic plate 41, and the side away from the inner elastic plate 41 has an opposite deflection trend as the inner elastic plate 41, so that the side of the inner fixed plate 42 away from the inner elastic plate 41 is more closely attached to the inner wall of the aqueduct 2. At the same time, the two inner fixed strips 43 make the two aqueducts 2 tend to approach each other, thereby improving the water-stopping effect.

[0059] As a preferred embodiment, the cross section of the inner fixing plate 42 is a triangle, 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 passes through the connecting plate 5 and is provided with a thread, a stretching nut 54 is connected to the thread, and the stretching nut 54 is located on the upper end surface of the connecting plate 5, a rotating drum 52 is rotatably arranged on the stretching shaft 51, and a plurality of guide vanes 53 are fixed to the outer wall of the rotating drum 52.

[0061] Among them, when the installation is completed, the pulling of the stretching shaft 51 by the stretching nut 54 can increase the movement trend of the middle position of the inner elastic plate 41, thereby further improving the water-stopping effect at the position where the water flow impact is more concentrated. At the same time, the guide vane 53 can be rotated by the water flow, thereby driving the water flow and mud to move and avoiding the accumulation of mud.

[0062] Specifically, first, the outer water-stop component 3 and the inner water-stop component 4 are respectively installed on the outer notch 21 and the inner notch 22, and then the outer water-stop component 3 and the inner water-stop component 4 are connected by the connecting plate 5. At this time, the outer sac 36 and the inner sac 4 are injected with air through the air injection equipment, so that pressure is applied in the direction in which the multiple aqueducts 2 approach each other, thereby improving the water-stopping effect. Finally, the pulling of the stretching shaft 51 by the stretching nut 54 can increase the movement trend of the middle position of the inner elastic plate 41, thereby further improving the water-stopping effect at the position where the water flow impact is more concentrated.

[0063] What is described above is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
