TECHNICAL FIELD
[0001] The utility model relates to gate structure technical field especially relates to a dam flood discharge gate structure. BACKGROUND
[0002] The gate plays a vital role in the dam flood discharge, they can accurately control the release amount of water flow, effectively regulate the reservoir water level, prevent flood, when the need to discharge flood, open the gate can quickly discharge excess water; and in the non-flood period, closing the gate can ensure the safety of the reservoir water storage, meet the needs of irrigation, power generation and so on.
[0003] The current dam flood discharge gate structure, in the closed state of the gate, its bottom will directly contact with the riverbed, however, when the gate is opened and runs for a period of time, the area below the gate may accumulate sand, this sand accumulation may mislead the operator, the specific performance is: when trying to close the gate, once the gate touches the sand below, the operator may mistakenly think that the gate has been completely closed, but these sand is not permanent stable, with the passage of time, they may gradually be lost, in this way, the gate that seems to be closed is not completely closed, thus may cause water leakage problem. SUMMARY
[0004] The dam flood discharge gate structure of the embodiment of the disclosure, by setting the movable push plate, after the opening and closing gate body is in the rising open state, two movable push plates will be moved inwards and combined under the action of the corresponding structure, so that the two movable push plates are below the opening and closing gate body, so that after the sand accumulation phenomenon occurs, the sand accumulation only exists on the movable push plate, and when the opening and closing gate body is ready to close, the movable push plate moves out with the sand, so that the sand accumulation can be avoided to affect the closing of the opening and closing gate body, and prevent the unnecessary trouble caused by the incomplete closing of the opening and closing gate body due to the sand accumulation.
[0005] In a first aspect, the dam flood discharge gate structure is provided, specifically comprising: a dam base body, a gate base body is fixedly installed inside the dam base body; a support base is fixedly installed on the front and back sides of the gate base body; a guide piece is fixedly installed on the outer left and right ends of the support base; the guide piece is in U-shaped structure; a guide slide rod is slidingly installed inside the guide piece; the guide slide rod is in cylindrical structure; a force receiving sliding block is fixedly installed at the inner end of the guide slide rod; the force receiving sliding block is also slidingly installed inside the guide piece; one end of a restoring spring is embeddedly installed on the outer side of the force receiving sliding block; the other end of the restoring spring is embeddedly installed on the inner side of the guide piece; a force receiving inclined groove is formed on the inner side top end of the force receiving sliding block; a connecting vertical plate is fixedly installed on the bottom of the force receiving sliding block; a movable push plate is fixedly installed on the inner side of the connecting vertical plate.
[0006] In at least some embodiments,
[0007] The bottom of the force inclined chute is in an inclined structure; the movable push plate is in a wide L-shaped structure, and a reinforcing rib plate is fixed to the bending part of the movable push plate.
[0008] In at least some embodiments,
[0009] The inside of the gate base body is slidably installed with an opening and closing gate body; top end positions on the front and back sides of the opening and closing gate body are fixedly installed with top pushing blocks; the top pushing blocks are in a rectangular structure.
[0010] In at least some embodiments,
[0011] The top of the gate base body is fixedly installed with a driving assembly in a central position; a driven screw is arranged on the driving assembly; the bottom end of the driven screw is further connected with the top end of the opening and closing gate body.
[0012] In at least some embodiments,
[0013] When the opening and closing gate body moves downward along the gate base body, the top pushing blocks on the opening and closing gate body push the inclined surface of the force inclined chute.
[0014] In at least some embodiments,
[0015] After the inclined surface of the force inclined chute is pushed, the force inclined chute, the connecting vertical plate and the two movable push plates relatively move outward; after the opening and closing gate body rises, the top pushing blocks cancel the pushing of the inclined surface of the force inclined chute.
[0016] In at least some embodiments,

[0018] The dam flood discharge gate structure has the following beneficial effects:
[0019] I. By arranging the movable push plates, when the opening and closing gate body is in a rising and completely opened state, the two movable push plates move inward and merge under the action of the corresponding precise structure and are positioned directly below the opening and closing gate body; such a design ensures that even if sand accumulation occurs, the sand accumulation will only accumulate on the movable push plates; during the process of preparing to close the opening and closing gate body, the movable push plates carry the sand accumulation and move outward; such a mechanism effectively avoids the interference of sand accumulation on the closing process of the opening and closing gate body, prevents incomplete closing of the opening and closing gate body due to sand accumulation, and thus avoids various unnecessary troubles that may be caused subsequently.
[0020] II. The dam flood discharge gate structure realizes the function of automatic triggering of the movable push plate to move in and merge when the opening and closing gate body is opened through a series of ingenious structural improvements. This function effectively blocks the riverbed below the opening and closing gate body, so that the accumulated sand can only accumulate on the movable push plate. When the opening and closing gate body needs to be closed, the movable push plate can automatically move away with the accumulated sand, thereby creating conditions for the smooth descent of the opening and closing gate body and close contact with the riverbed. Such design cooperation ensures that the opening and closing gate body can be closed thoroughly enough. BRIEF DESCRIPTION OF DRAWINGS
