[0043] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings, wherein the accompanying drawings constitute a part of the present application and are used together with the embodiments of the present invention to illustrate the principles of the present invention, but are not used to limit the scope of the present invention.

[0044] like Figure 1 and Figure 2 As shown, the utility model provides a water level change zone connection device, including a main structure 1, a structure to be installed 2 and a sealing structure 3, the main structure 1 includes a bracket 11 and a first fixed plate 12, the bracket 11 is hollow inside and one end is open, and the first fixed plate 12 is connected to the open end of the bracket 11; the structure to be installed 2 includes a steel component 21 and a second fixed plate 22, the steel component 21 is hollow inside and at least one end is open, the second fixed plate 22 is connected to the open end of the steel component 21, and the second fixed plate 22 is detachably connected to the first fixed plate 12; the sealing structure 3 is arranged between the first fixed plate 12 and the second fixed plate 22.

[0045] When the main structure 1 needs to be connected to the structure to be installed 2, first align the second fixing plate 22 with the first fixing plate 12, and then fasten the second fixing plate 22 and the first fixing plate 12 together. At this time, the sealing structure 3 is compressed to ensure the sealing of the connection; when the structure to be installed 2 needs to be disassembled or replaced, just loosen the connection between the first fixing plate 12 and the second fixing plate 22, and the structure to be installed 2 can be easily removed; through the detachable connection between the first fixing plate 12 and the second fixing plate 22, there is no need to fix it by welding, and construction and installation can be carried out even if the water level rises. The detachable connection is much less affected by the rise and fall of the water level than welding. By setting the sealing structure 3, the sealing of the connection between the main structure 1 and the structure to be installed 2 is ensured; the bracket 11 adopts an internal hollow structure, which can reduce the weight of the main structure 1; by setting the first fixed plate 12 at the open end of the bracket 11, the first fixed plate 12 can block the open end of the bracket 11 to prevent air and water from entering the internal cavity through the open end; the steel component 21 adopts a hollow structure to reduce the weight of the structure to be installed 2; by setting the second fixed plate 22, the second fixed plate 22 can block the open end of the steel structure to prevent air and water from entering the internal cavity through the open end.

[0046] like Figure 1 , Figure 2 and Figure 3 As shown, in one of the embodiments, the number of main structures 1 is at least two; the structure 2 to be installed is arranged between two adjacent main structures 1, both ends of the steel component 21 are open, and both open ends of the steel component 21 are connected to second fixing plates 22, and the second fixing plates 22 at the two open ends of the steel component 21 are respectively detachably connected to the first fixing plates 12.

[0047] Two adjacent main structures 1 can be connected via the structure to be installed 2, so that the two adjacent main structures 1 can be fixed.

[0048] like Figure 1 and Figure 2 As shown, in one embodiment, the bracket 11 includes a vertical steel pipe 111 and a horizontal steel pipe 112, and the horizontal steel pipe 112 is connected to the vertical steel pipe 111; the first fixed plate 12 is arranged on a side of the horizontal steel pipe 112 away from the vertical steel pipe 111, and is connected to the horizontal steel pipe 112.

[0049] The water level change zone connection device further includes a connection member 4 , which can detachably connect the first fixed plate 12 and the second fixed plate 22 .

[0050] By setting the bracket 11 as the above-mentioned vertical steel pipe 111 and horizontal steel pipe 112, the vertical steel pipe 111 in the bracket 11 can play a supporting role, and the horizontal steel pipe 112 in the bracket 11 can play a role in connecting the adjacent structure to be installed 2 and the bracket 11; the connecting member 4 can play a role in connecting the first fixed plate 12 and the second fixed plate 22.

[0051] It should be understood that the connecting member 4 may be a combination of a bolt and a nut, or the connecting member 4 may be a bolt threadedly connecting the first fixing plate 12 and the second fixing plate 22 .

[0052] It should be understood that the number of the connecting members 4 corresponds one to one to the number of the first fixing holes.

[0053] It should be understood that the cross-sections of the steel component 21 , the vertical steel pipe 111 and the horizontal steel pipe 112 may be circular, square, polygonal, etc.

[0054] It should be understood that the other open ends of the vertical steel pipe 111 and the horizontal steel pipe 112 are closed or closed by the first fixing plate 12 .

[0055] like Figure 1As shown, in one embodiment, the first fixing plate 12 is provided with a plurality of first fixing holes along the circumferential direction; the second fixing plate 22 is provided with a plurality of second fixing holes relative to the first fixing holes; the connecting member 4 passes through the first fixing holes and the second fixing holes, and is detachably connected to the first fixing plate 12 and the second fixing plate 22.

[0056] By providing the first fixing hole and the second fixing hole, the connecting member 4 is passed through the first fixing plate 12 and the second fixing plate 22 , thereby achieving the fixing of the connecting member 4 to the first fixing plate 12 and the second fixing plate 22 .

[0057] like Figure 1 As shown, in one embodiment, the connecting member 4 includes a bolt 41 and a nut 42 . The bolt 41 can be rotated through the first fixing hole and the second fixing hole, and the nut 42 is threadedly connected to the bolt 41 .

[0058] By providing the bolt 41 and the nut 42 , passing the bolt 41 through the first fixing hole and the second fixing hole, and then threading the nut 42 to the bolt 41 , the detachable connection between the first fixing plate 12 and the second fixing plate 22 is achieved.

[0059] In one embodiment, the sealing structure 3 is a rubber disc.

[0060] By setting the sealing structure 3 as a rubber disc, when the first fixed disc 12 and the second fixed disc 22 clamp the rubber disc, the rubber disc can be tightly attached to the first fixed disc 12 and the second fixed disc 22, and the rubber disc is compressed, and an elastic restoring force can be applied to the first fixed disc 12 and the second fixed disc 22, so that the first fixed disc 12 and the second fixed disc 22 are stable, and the rubber disc can play a water-stopping effect, which can prevent water from entering between the first fixed disc 12 and the second fixed disc 22, thereby playing a water-stopping role.

[0061] like Figure 1 As shown, in one embodiment, the rubber disc is provided with a plurality of third fixing holes opposite to the plurality of first fixing holes; the bolts 41 pass through the rubber disc through the third fixing holes.

[0062] By opening a third fixing hole on the rubber disc and passing the bolt 41 through the rubber disc through the third fixing hole, the cooperation between the bolt 41 and the third fixing hole can limit the position of the rubber disc and position the rubber disc so that the rubber disc is at a preset position between the first fixing disc 12 and the second fixing disc 22, thereby achieving the effect of water stopping and pre-tightening.

[0063] like Figure 1 As shown, in one embodiment, the third fixing holes are arranged in a one-to-one correspondence with the first fixing holes.

[0064] By arranging the third fixing holes in a one-to-one correspondence with the first fixing holes, the rubber disc can be positioned and fixed by the bolts 41 .

[0065] like Figure 4 As shown, in one embodiment, the third fixing hole is larger than the first fixing hole, the inner wall of the third fixing hole extends inward to form an annular gasket 31, the inner diameter of the annular gasket 31 is equal to the inner diameter of the first fixing hole, and the thickness of the annular gasket 31 along the axial direction of the rubber disk is less than the thickness of the rubber sheet along the axial direction.

[0066] Through the above arrangement, when the bolt 41 passes through the rubber disc, due to the processing accuracy problem of the first fixing hole and the second fixing hole, the position of the hole may deviate. If the inner diameter of the third fixing hole is equal to the first fixing hole, some bolts 41 may not be able to quickly pass through the third fixing hole, affecting the construction efficiency. For this reason, in the present application, the inner diameter of the third fixing hole is set to be larger than the first fixing hole, and an annular gasket 31 is formed in the third fixing hole, so that the bolt 41 can enter the third fixing hole with a larger diameter. Moreover, since the thickness of the annular gasket 31 is relatively thin, even if there is a deviation, the bolt 41 can easily push the annular gasket 31 to deform, and then pass through the annular gasket 31 and the rubber disc. Moreover, the inner diameter of the annular gasket 31 is equal to the inner diameter of the first fixing hole, so that after the bolt 41 passes through the annular gasket 31, the annular gasket 31 can fix the rubber disc; moreover, when the first fixing disc 12 and the second fixing disc 22 squeeze the rubber disc, the rubber disc can deform toward the first fixing hole to avoid being subjected to excessive squeezing force.

[0067] like Figure 1 and Figure 2 As shown, in one embodiment, the first fixing plate 12 and the second fixing plate 22 are circular.

[0068] By arranging the first fixing plate 12 and the second fixing plate 22 into a circle, the circular first fixing plate 12 and the second fixing plate 22 are subjected to uniform force in all directions, which enables the first fixing plate 12 and the second fixing plate 22 to better disperse the pressure when subjected to external force, thereby improving the stability and safety of the connection.

[0069] 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 changes or substitutions that can be easily thought of by any technician familiar with the technical field within the technical scope disclosed in the present invention should be included in the protection scope of the present invention.
