[0002] A hydraulic gate is a small flat gate that is widely used in water intake and water transfer, municipal construction, water supply and drainage, farmland irrigation and other projects. The existing gates are generally set at the water inlet of the water pipe, used as working gates to regulate flow and control water levels, or used as maintenance gates to close the orifices to block water.

[0003] For example, the existing utility model patent (publication number CN217174619U) discloses a gate for water conservancy projects, including a canal, a fixed baffle in the canal, symmetrical inclined plates fixed on both sides of the lower part of the baffle, the symmetrical inclined plates are fixed to the canal, openings are provided on the inclined plates, the openings match the baffles, the baffles are fixed with a rotating shaft, and one end of each rotating shaft is hinged to one side of the canal.

[0004] Although the valve in the above prior art is convenient for drainage, the corrosion degree of the water retaining plate will gradually increase during long-term use, and the subsequent maintenance cost is relatively high. To this end, we provide a gate opening and closing device for water conservancy projects to solve the above problems. Utility Model Content

[0005] The purpose of the utility model is to provide a gate opening and closing device for water conservancy projects, which solves the above-mentioned technical problems.

[0006] In order to solve the above technical problems, the utility model is realized by the following technical solutions:

[0007] The utility model is a gate opening and closing device for water conservancy projects, comprising a gate body; the gate body comprises a side column, a crossbeam fixed to the top of the side column, a mounting seat embedded and fixed in the middle of the crossbeam, a screw threaded through the middle position of the mounting seat, a connecting piece arranged at the bottom of the screw, a gate plate fixed by bolts and the connecting piece, a corrugated plate welded to the inner side of the gate plate, and a reinforcing rib integrally arranged on the outer side of the gate plate.

[0008] The utility model is further configured that a groove is provided on the side surface of the side column, and the edge of the side column is fixed to the outer contact surface through bolts.

[0009] The utility model is further configured that an extension plate is arranged on the side of the gate plate, and the extension plate is movably arranged in a slide groove arranged on the inner wall of the side column.

[0010] The utility model is further configured that the corrugated plate is a metal hollow structure, and the surface of the corrugated plate is coated with anti-corrosion paint.

[0011] The utility model is further configured such that the edge of the corrugated plate fits the inner wall of the side column, and the peak height of the corrugated plate is located inside the inner side surface of the side column.

[0012] The utility model is further configured that the raised surface of the corrugated plate is triangular, and the crest angle of the corrugated plate is set at a right angle.

[0013] The top of the corrugated plate is provided with a vertical extension surface, which is in contact with the gate plate, and the vertical extension surface and the gate plate are both matched and arranged in the lower groove body of the connecting member, and a triangular plate is symmetrically fixed on the upper part of the connecting member.

[0014] The upper connecting end of the connecting piece has a built-in ball nut seat, and the ball nut seat is spirally matched with the lower end of the screw rod.

[0015] Compared with the prior art, the utility model has the following beneficial effects:

[0016] The utility model effectively blocks turbulence and wave impact by adding a corrugated plate structure on the inner side of the gate plate, thereby improving the structural strength of the corrugated plate. The vertical reinforcing ribs integrally arranged on the outer side surface can improve the structural strength of the gate plate. When the gate opening and closing device is in use, the screw is driven to rotate by an external drive, and the screw drives the connecting piece to rotate synchronously, thereby making the gate plate vertically rise and fall along the side column. In the daily closed state, the impact of waves on the water surface and turbulence below the liquid surface on the gate plate will be blocked by the corrugated plate, so as to achieve a protective effect on the gate plate.

[0025] 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. Example

[0026] See also Figure 1-4 The present embodiment discloses a gate opening and closing device for a water conservancy project, comprising a gate body 1; the gate body 1 comprises a side column 12, a crossbeam 11 fixed to the top of the side column 12, a mounting seat 14 embedded and fixed in the middle of the crossbeam 11, a screw rod 15 threadedly penetrated through the middle position of the mounting seat 14, a connecting piece 16 arranged at the bottom of the screw rod 15, a gate plate 18 fixed by bolts and the connecting piece 16, a corrugated plate 17 welded to the inner side of the gate plate 18, and a reinforcing rib 19 integrally arranged on the outer side of the gate plate 18.

[0027] Specifically, in the gate opening and closing device for water conservancy projects involved in this embodiment, by installing a corrugated plate 17 structure inside the gate plate 18, turbulence and wave impact are effectively blocked, and the structural strength of the corrugated plate 17 is improved. The vertical reinforcing ribs 19 integrally arranged on the outer side thereof can improve the structural strength of the gate plate 18. When in use, the screw 15 is driven to rotate by an external drive, and the screw 15 drives the connecting member 16 to rotate synchronously, thereby causing the gate plate 18 to rise and fall along the side column 12. In the daily closed state, the impact of waves on the water surface and turbulence below the liquid surface on the gate plate 18 will be blocked by the corrugated plate 17, so as to protect the gate plate 18.

[0028] Furthermore, a groove is provided on the side of the side column 12, and the edge of the side column 12 is fixed to the outer contact surface by bolts; an extension plate 110 is provided on the side of the gate plate 18, and the extension plate 110 is movably provided in the slide groove 13 provided on the inner wall of the side column 12.

[0029] Specifically, the side column 12 serves as the main frame structure of the gate body 1, and is also used for fixing the gate body 1 with the external mounting surface to ensure the overall stability of the gate body 1. The internally arranged slide groove 13 cooperates with the extension plate 110 to achieve the lifting balance of the gate plate 18. The setting of the extension plate 110 assists the gate plate 18 in balancing while reducing the degree of water corrosion of the gate plate 18. If the edge of the gate plate 18 is directly set in the slide groove 13, its side wall will inevitably wear during the lifting and lowering process, resulting in damage to its surface structure. Long-term immersion in water will accelerate its rust and corrosion. Therefore, the cost of replacing and repairing the extension plate 110 structure welded alone is relatively low even if it is corroded and damaged.

[0030] The corrugated plate 17 is a metal hollow structure, and the surface of the corrugated plate 17 is coated with anti-corrosion paint; the edge of the corrugated plate 17 is in contact with the inner wall of the side column 12, and the peak of the corrugated plate 17 is located inside the inner side of the side column 12; the raised surface of the corrugated plate 17 is triangular, and the peak angle of the corrugated plate 17 is set at a right angle.

[0031] Specifically, the corrugated plate 17 with a metal hollow structure is used to protect the gate plate 18. At the same time, the hollow structure reduces the deadweight of the corrugated plate 17 to avoid the increase of subsequent traction load. In addition, in order to prevent the corrugated plate 17 from being easily corroded during long-term use, an anti-corrosion paint is applied on its surface. The triangular wave setting can effectively block turbulence and wave impact, and improve the structural strength of the corrugated plate 17.

[0032] Furthermore, a vertical extension surface is provided on the top of the corrugated plate 17, and the vertical extension surface is in contact with the gate plate 18, and the vertical extension surface and the gate plate 18 are both cooperatedly arranged in the lower groove body of the connecting member 16, and a triangular plate is symmetrically fixed on the upper part of the connecting member 16; a ball nut seat is built into the upper connecting end of the connecting member 16, and the ball nut seat is spirally matched with the lower end of the screw 15.

[0033] Specifically, the vertical extension surface integrally provided on the top of the corrugated plate 17 and the top of the gate plate 18 are fixed to the connecting piece 16 by bolts, so as to reinforce the connection between the corrugated plate 17 and the gate plate 18. The triangular plate symmetrically fixed on the upper part of the connecting piece 16 is used to reinforce its own structural stability. After the ball nut seat embedded in the connecting piece 16 cooperates with the screw rod 15, the connecting piece 16 rises and falls with the screw rod 15 during the rotation and lifting process of the screw rod 15, but is not subject to the torsional interference of the screw rod 15 in its rotation.
