[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] Reference Figure 1-Figure 4 The water conservancy pipeline interface connection device provided in this embodiment includes a first hoop body 1 and a second hoop body 2 that cooperate with each other to form a clamp structure, a sealing ring 3 capable of telescopic compensation is arranged between the first hoop body 1 and the second hoop body 2, and a compensation component 4 is arranged on the first hoop body 1 and the second hoop body 2. A connecting bolt 6 is arranged on the first hoop body 1 through a first connecting plate 5, and a connecting screw hole 8 that cooperates with the connecting bolt 6 is opened on the second hoop body 2 through a second connecting plate 7.

[0024] In the utility model, when the pipeline interface connection device is installed, the first hoop body 1 and the second hoop body 2 form a clamp structure through the connecting bolts 6 on the first connecting plate 5 and the connecting screw holes 8 on the second connecting plate 7, and the sealing ring 3 is installed in the clamping groove of the clamp structure. As the connecting bolts 6 are locked, the first hoop body 1 and the second hoop body 2 are locked and the sealing ring 3 is pressed and fixed at the interface position of the pipeline. The compensation component 4 arranged in the first hoop body 1 and the second hoop body 2 can be expanded and contracted along the axial direction of the pipeline, so as to absorb the axial displacement of the pipeline caused by thermal expansion and contraction, and ensure that the pipeline interface always maintains a tight fit.

[0025] Specifically, Figure 2 and Figure 3 As shown, an airbag 31 capable of being inflated and deflated is arranged in the sealing ring 3 , an inflation nozzle 32 connected to the airbag 31 is arranged on the sealing ring 3 , and a locking cap 33 is threadedly connected to the inflation nozzle 32 .

[0026] Among them, when the pipeline interface expands and contracts due to temperature changes, specifically, when the ambient temperature rises, the water conservancy pipeline will expand due to the heat, and its diameter and length may increase slightly. When the temperature drops, the pipeline will shrink. When the pipeline expands or shrinks, a gap will appear between the sealing ring 3 and the fitting surface of the pipeline. At this time, the locking cap 33 is opened, and the air bag 31 in the sealing ring 3 is inflated and deflated through the inflation nozzle 32, so that the sealing ring 3 always maintains a close fit with the inner wall of the pipeline to ensure that the sealing is not affected.

[0027] It should be noted that the airbag 31 includes a plurality of inflation chambers 311 evenly arranged in the sealing ring 3 , and adjacent inflation chambers 311 are connected via inflation channels 312 .

[0028] Among them, several evenly distributed inflation chambers 311 can ensure that each surface of the sealing ring 3 can change evenly during inflation or deflation, thereby ensuring that the sealing ring 3 always fits the pipeline, and the inflation channel 312 can ensure that each inflation chamber 311 can be connected.

[0029] Specifically, Figure 1 and Figure 2 As shown, the first hoop body 1 is provided with an outer protective tube 11 penetrating the top thereof, a protective cover 12 is threadedly connected to the outer protective tube 11 , and an inflation nozzle 32 penetrates the first hoop body 1 and is located inside the outer protective tube 11 .

[0030] Among them, during normal use, the inflation nozzle 32 and the locking cap 33 will be located in the outer protective tube 11. After the protective cover 12 is tightened, the outer protective tube 11 will provide safety protection for the inflation nozzle 32 to prevent the inflation nozzle 32 from being damaged due to collision with foreign objects during use. When the sealing ring 3 needs to be inflated or deflated, the protective cover 12 is unscrewed, and then the inflation nozzle 32 can be used for inflation or deflation.

[0031] Specifically, Figure 2 and Figure 4 As shown, the compensation component 4 includes a baffle 41 fitted with the sealing ring 3, a connecting shaft 42 penetrating the first hoop body 1 or the second hoop body 2 is arranged on the baffle 41, and a rubber pad 43 is sleeved on the outside of the connecting shaft 42.

[0032] Among them, the rubber pad 43 is in the shape of an oblate sphere and can have a certain elasticity. When the pipeline produces axial displacement due to thermal expansion and contraction, the axial displacement can be compensated by the contraction of the rubber pad 43, ensuring that the pipeline interface always maintains a tight fit, thereby significantly reducing the risk of leakage.

[0033] It should be noted that a threaded end 44 is provided at one end of the connecting shaft 42 away from the baffle 41 , and a locking nut 45 abutting against the outside of the first hoop body 1 or the second hoop body 2 is provided on the threaded end 44 .

[0034] The connecting shaft 42 is detachably connected to the first hoop body 1 and the second hoop body 2 by connecting in a manner of threaded end 44 and locking nut 45, so that the compensation component 4 can be disassembled when the locking nut 45 on the threaded end 44 is unscrewed, thereby facilitating maintenance and repair of the compensation component 4.

[0035] Specifically, Figure 2 As shown, the first connecting plate 5 is provided with an inserting plate 51 , and the second connecting plate 7 is provided with an inserting hole 71 matched with the inserting plate 51 .

[0036] When the first hoop body 1 and the second hoop body 2 are connected by the connecting bolt 6 and the connecting screw hole 8, before the connecting bolt 6 is installed, the first hoop body 1 and the second hoop body 2 are combined, and the plug plate 51 is inserted into the plug hole 71, so that the first hoop body 1 and the second hoop body 2 are connected in a snap-fit ​​manner, which is convenient for the subsequent connection of the connecting bolt 6, and then the connection of the first hoop body 1 and the second hoop body 2 can be facilitated;

[0037] It should be noted that the plug plate 51 is composed of a straight plate and a wedge-shaped limit head at the bottom of the straight plate. The straight plate itself has a certain elasticity. When the plug plate 51 is inserted, the plug plate 51 will be slightly tilted under the action of the socket 71. When the limit head at the bottom of the plug plate 51 completely passes through the socket 71, the plug plate 51 will be reset. At this time, the limit head on the plug plate 51 abuts against the second connecting plate 7, thereby realizing the connection between the first hoop body 1 and the second hoop body 2.

[0038] The above description 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 within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
