Description

Technical Field

[0001] The utility model relates to the field of water diversion and regulation engineering, in particular to a flood control sluice. Background Art

[0002] Water conservancy engineers use water conservancy engineers to control and allocate natural surface water and groundwater to achieve the purpose of eliminating harm and promoting benefits. The project is also called water engineering. Water is an indispensable and precious resource for human production and life, but its natural state does not fully meet human needs. In existing water conservancy projects, sluice gates are often used. The gate moves up and down in the gate beam to open and close the water flow, which plays a role in controlling the waterway to meet the needs of irrigation, power generation, shipping, aquatic products, environmental protection, industry, flood control and domestic water. In order to ensure the sealing of the gate, a sealing groove is usually opened at the bottom of the mounting frame so that the gate can extend into the sealing groove.

[0003] After searching, the Chinese patent publication number is CN220685972U, which discloses a flood control sluice for water diversion and regulation projects. When the flood control sluice is actually used, the concrete slurry flowing out of the branch can wrap the soil around the branch, and the sliding pipe can be firmly connected to the river soil. When the flood control sluice is actually used, the top plate is connected to the sliding pipe through the first sleeve and the plug-in block, and the top plate and the sliding pipe can be separated for transportation, which is convenient for the sliding pipe and the top plate to be installed in the soil.

[0004] However, when the gate is opened, the sealing groove leaks out and the silt in the water flow may settle into the sealing groove, thus affecting the sealing of the gate. Utility Model Content

[0026] An auxiliary mechanism is provided in the sealing groove, and the auxiliary mechanism includes a bottom plate 401 slidably connected in the mounting groove, a spring 402 is connected between the bottom plate 401 and the bottom of the sealing groove, a connecting plate 403 is rotatably connected to the top of the bottom plate 401, both ends of the connecting plate 403 abut against the inner wall of the mounting frame 1, a torsion spring is provided between the connecting plate 403 and the bottom plate 401, and a sealing cloth 404 is connected between the connecting plate 403 and the bottom plate 401, and the sealing cloth 404 is elastic. The two ends of 4 are connected to the inner wall of the mounting frame 1, and the sealing cloth 404 is used to prevent water from entering between the bottom plate 401 and the connecting plate 403, so that the mud and sand are retained in the gap between the bottom plate 401 and the connecting plate 403. A plurality of through holes are provided on the top of the connecting plate 403, and a limiting groove connected to the sealing groove is provided in the mounting frame 1. A slider 4011 is fixedly connected to the bottom plate 401, and the slider 4011 is slidably connected in the limiting groove, and the bottom plate 401 is limited by the limiting groove.

[0027] A discharge mechanism 5 is provided on the gate 2, and the discharge mechanism 5 is used to reduce the downward impact force received by the gate 2 during the opening process, thereby reducing the resistance to the gate 2 being lifted. The discharge mechanism 5 includes a transverse plate 501, and the transverse plate 501 is bolted to the front side of the gate 2. A hydraulic cylinder 502 is fixedly connected to the top of the transverse plate 501, and a baffle 503 is fixedly connected to the top of the hydraulic cylinder 502. A plurality of discharge holes 504 are provided on the front side of the gate 2, and the discharge holes 504 are located in the middle and upper part of the gate 2. During the opening process of the gate 2, the baffle 503 is moved downward by controlling the hydraulic cylinder 502 to open the discharge holes 504, and pressure is released through the discharge holes 504 to reduce the downward impact force received by the gate 2 during the opening process, thereby reducing the resistance to the gate 2 being lifted.

[0028] Working principle: When the gate 2 needs to be opened to divert water, the rotating motor 301 is started, the rotating motor 301 drives the screw 302 to rotate, and the screw 302 drives the gate 2 to rise along the mounting frame 1. At the same time, the baffle 503 is moved downward by controlling the hydraulic cylinder 502 to open the drain hole 504, and the pressure is released through the drain hole 504 to reduce the downward impact force received by the gate 2 during the opening process, thereby reducing the resistance to the gate 2 lifting.

When the gate 2 is closed, the gate 2 first contacts the higher end of the connecting plate 403, and then presses the connecting plate 403 to squeeze the water between the connecting plate 403 and the bottom plate 401 through the through holes on the connecting plate 403 to form a backflow, which recoils the silt on the surface of the connecting plate 403, and the gate 2 continues to move downward until the bottom plate 401 and the connecting plate 403 are completely pressed into the sealing groove.
