[0021] 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 in 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.

[0022] Embodiment 1

[0023] like Figure 1 As shown:

[0024] A channel-spanning bridge structure for water conservancy engineering construction comprises a bridge body 1.

[0025] In this implementation scheme: the existing {public announcement number}: CN217810462U discloses a cross-channel bridge structure for water conservancy project construction. This patent discloses a bridge plate. The bridge body 1 in the present application document adopts the same technical means in this prior art. This technical means will not be described one by one here. For details about the improvement of this prior art, please refer to the disclosed technology below; to solve the technical problems existing in this prior art, as disclosed in the background technology above, "when the bottom of the bridge is blocked, it is difficult to conveniently clear the debris at the bottom of the device, which will affect the normal flow of water conservancy, and then affect the irrigation of farmland and the transfer of water resources". In terms of combined use, this problem is obviously a real problem that exists and is relatively difficult to solve. In view of this, in order to solve the above problems, a connecting shaft 2 and a limit block 3 are added on this basis.

[0026] More specifically:

[0027] like Figure 1 - Figure 4 As shown:

[0028] In combination with the above content: it also includes a connecting shaft 2, a limiting block 3, a dredging frame 4, a closing plate 5, a support plate 6, a groove 7 and a limiting plate 8 arranged on one side of the bridge body 1. The surface of the bridge body 1 is fixedly installed with a connecting shaft 2 that is rotatably connected to one end of the limiting block 3, and the inner surface of the bridge body 1 is also slidably connected to the dredging frame 4, and the surface of the dredging frame 4 is rotatably connected with a closing plate 5 that is slidably connected to the inner surface of the bridge body 1 on both sides, and the surface of the dredging frame 4 is also fixedly installed with a support plate 6, the surface of the support plate 6 is provided with a support plate 6, and the end of the support plate 6 away from the dredging frame 4 is also fixedly installed with a limiting plate 8 that is fitted and connected to the closing plate 5.

[0029] In this embodiment: when the dredging frame 4 is working, the limit block 3 maintains a normal drooping state and is located on both sides of the bridge body 1 to block the dredging frame 4. At this time, the water flow will flow normally through the dredging frame 4 and between them. When a blockage occurs inside, the staff can rotate the limit block 3 and the connecting shaft 2 180 degrees. At this time, the dredging frame 4 is no longer blocked by the limit block 3, and the dredging frame 4 and the closing plate 5 can be pulled out from the bottom of the bridge body 1 through the groove 7 opened on the surface of the support plate 6, and the dredging frame 4 and the closing plate 5 can also be pulled out together. When the dredging frame 4 is completely separated from the bridge body 1, the closing plate 5 can rotate with the dredging frame 4 and separate from the limiting plate 8. When the closing plate 5 is opened, the impurities inside can be easily cleaned. Then the closing plate 5 can be closed again, and the limiting plate 8 set on the top of the supporting sheet 6 can prevent the two closing plates 5 from excessive rotation. Then the dredging frame 4 and the closing plate 5 can be put back to the bottom of the bridge body 1 and the position of the dredging frame 4 can be blocked by the limiting block 3.

[0030] Going further:

[0031] In an optional embodiment, the connecting shaft 2 and the limiting block 3 are symmetrically arranged on both sides of the surface of the bridge body 1 .

[0032] In this embodiment: the connecting shaft 2 and the limit block 3 symmetrically arranged on both sides of the bridge body 1 can enable both ends of the dredging frame 4 to be limited by the connecting shaft 2 and the limit block 3, thereby avoiding the displacement of the dredging frame 4 under the influence of long-term water flow.

[0033] Going further:

[0034] In an optional embodiment, the limiting block 3 is elliptical in shape, and a circular hole matching the connecting shaft 2 is formed at one end of the limiting block 3 .

[0035] In this embodiment, the elliptical limiting block 3 can block and release the dredging frame 4 before and after its rotation, and the through hole opened on the surface of the limiting block 3 can form a sufficiently stable connection with the connecting shaft 2.

[0036] Going further:

[0037] In an optional embodiment, the dredging frame 4 and the closing plate 5 form a half-cylindrical geometric body.

[0038] In this embodiment: the half-cylindrical dredging frame 4 and the closing plate 5 can form a good connection with the bottom of the bridge body 1, and at the same time can ensure that no resistance is generated to the water flow passing through the bottom of the bridge body 1.

[0039] Going further:

[0040] In an optional embodiment, the closing plates 5 are symmetrically arranged on both sides of the surface of the dredging frame 4 .

[0041] In the present embodiment: the closing plates 5 symmetrically arranged on both sides of the dredging frame 4 can form an effective connection between it and the surface of the bridge body 1, and can also prevent debris from forming a connection with the bridge body 1 when blockage occurs inside the dredging frame 4 and the closing plates 5, thereby making it easier to pull out the dredging frame 4.

[0042] Going further:

[0043] In an optional embodiment, the drawing grooves 7 are symmetrically arranged at two ends of the supporting sheet 6 .

[0044] In this embodiment: the grooves 7 symmetrically arranged on both sides of the surface of the support plate 6 can conveniently remove the dredging frame 4 from the inside of the bridge body 1 through the grooves 7 and the support plate 6, so that the staff can get a convenient fulcrum from the outside, which can be beneficial to the efficiency of dredging.

[0045] The working principle and use process of the utility model are as follows: when the dredging frame 4 is working, the limit block 3 maintains a normal drooping state and is located on both sides of the bridge body 1 to block the dredging frame 4. At this time, the water flow will flow normally through the dredging frame 4 and between them. When a blockage occurs inside, the staff can rotate the limit block 3 and the connecting shaft 2 180 degrees. At this time, the dredging frame 4 is no longer blocked by the limit block 3, and the dredging frame 4 and the closing plate 5 can be pulled out from the bottom of the bridge body 1 through the groove 7 opened on the surface of the support sheet 6, and pulled out together. When the dredging frame 4 is completely separated from the bridge body 1, the closing plate 5 can rotate with the dredging frame 4 and separate from the limiting plate 8. When the closing plate 5 is opened, the impurities inside can be easily cleaned, and then the closing plate 5 can be closed again. The limiting plate 8 set on the top of the supporting sheet 6 can prevent the two closing plates 5 from excessive rotation. Then the dredging frame 4 and the closing plate 5 can be put back to the bottom of the bridge body 1 and the position of the dredging frame 4 can be blocked by the limiting block 3.

[0046] Finally, it should be noted that the above are only preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions described in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
