Description

Technical Field

[0001] The utility model relates to the technical field of flood discharge gates, in particular to a water conservancy flood discharge gate. Background Art

[0002] The gate is a special device mainly used for flood discharge in reservoirs. It can control the water level in the reservoir and provide open water supply to dry land.

[0003] When the flood discharge gates currently in use are opened, the turbulent water flow will continuously impact the gate opening, and foreign objects mixed in the water flow will also flow out downstream. At the same time, in order to prevent the fish and shrimp in the reservoir from being washed away, fishing nets need to be placed inside the gates. However, due to the interference of turbulent water flow and foreign objects, the placed fishing nets are easily washed away.

[0004] When the gates are opened to release floodwater, how to prevent the fishing nets placed at the gates from being washed away by the turbulent water and foreign objects in the water is a technical difficulty that needs to be solved. Utility Model Content

[0005] The utility model aims to solve one of the technical problems existing in the prior art or related technology.

[0006] To this end, the technical solution adopted in this utility model is:

[0007] A water conservancy flood discharge gate comprises a blocking mechanism and a flood discharge mechanism installed in the blocking mechanism, the blocking mechanism comprises a horizontal rail, four protective outer plates fixedly installed at both ends of the horizontal rail, two brackets respectively installed on the inner sides of two adjacent protective outer plates, a beam plate fixedly installed on the top of the bracket, a screw rod movably installed inside the beam plate, a base located at the bottom of the screw rod, a cushion located in the base and two inclined frames movably installed on both sides of the base, the flood discharge mechanism comprises two gates movably installed on the inner sides of two adjacent protective outer plates, a baffle fixedly installed on the inner side transverse tube of the gate, a bottom sealing plate installed at the bottom of the gate, a top sealing plate installed at the top of the gate, a column fixedly installed on the top of the top sealing plate, a reinforcing torsion spring connected between the top sealing plate and a vertical shaft, a plurality of winding rollers fixedly installed outside the vertical shaft and a steel cable wound in an annular groove outside the winding roller.

[0008] In a preferred example, the utility model can be further configured as follows: the lying rail and the protective outer plate are both made of stainless steel material, and two limiting rails are fixedly installed on the inner side of the top end of the protective outer plate.

[0009] By adopting the above technical solution, four protective outer plates are fixedly installed on the top of the two ends of the horizontal rail. At this time, the two adjacent protective outer plates will provide an adaptive cavity for the lateral movement of the gate. Combined with the positioning constraints of the two protective outer plates on the square steel inside the gate, the lateral movement of the gate can be stably achieved.

[0010] In a preferred example, the utility model can be further configured as follows: a stainless steel threaded sleeve is fixedly installed in the middle of the beam plate, and a screw rod is movably installed inside the stainless steel threaded sleeve, and the inclined frame is composed of two reinforcing steel plates and guide rods fixed to the outer ends of the two reinforcing steel plates.

[0011] By adopting the above technical solution, the beam plate is fixedly installed on the top of the two supports, and the pad is fixed to the bottom of the screw with bolts. When the rotating wheel at the top of the screw is controlled to rotate, the base assembled at the bottom of the screw can apply a uniform downward thrust to the two inclined frames.

[0012] In a preferred example, the utility model can be further configured as follows: the gate is welded from square steel and a plurality of transverse tubes, and slots adapted for the baffles are provided at the top and the bottom of the transverse tubes.

[0013] By adopting the above technical solution, multiple baffles are fixedly installed on multiple horizontal tubes respectively. At this time, the gates and multiple baffles in a load-bearing state can move outward along the slideway on the top of the horizontal rail after being thrust. At this time, multiple steel cables located in the inner cavities of the two gates will be tightened.

[0014] In a preferred example, the utility model can be further configured as follows: the top of the bottom sealing plate and the bottom of the top sealing plate are both installed with end tubes, and the vertical axis is formed by welding a circular end column and a cross-shaped plug rod.

[0015] By adopting the above technical solution, the bottom sealing plate and the top sealing plate are fixedly installed on the bottom and top of the square tube inside the gate respectively by bolts. At this time, the two ends of the vertical axis will be movably installed inside the two end tubes, and the two ends of the reinforced torsion spring are respectively fixed between the vertical axis and the top sealing plate. As the gate moves laterally outward, the steel cable can be continuously released from the outside of the winding roller.

[0016] By adopting the above technical solution, the beneficial effects achieved by the utility model are:

[0017] 1. The utility model places the fishing net on one side of the two gates submerged in the water in advance, and then manually adjusts the screw rod to rotate clockwise. As the bottom end of the screw rod cooperates with the continuous decline of the base, the two inclined frames will simultaneously apply thrust to the two gates outward until the two gates open outward. At the moment when the water flow leaks out, the water pressure will press the fishing net tightly against the outside of the multiple steel cables. At this time, the two gates in the flood discharge state can provide sufficient compressive bearing capacity for the placed fishing net, and the water pressure and foreign objects can be prevented from washing down the fishing net during the flood discharge.

[0026] In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model is further described in detail below in combination with specific implementation methods and with reference to the accompanying drawings. It should be noted that the embodiments of the utility model and the features in the embodiments can be combined with each other without conflict.

[0027] It should be understood that these descriptions are exemplary only and are not intended to limit the scope of the present invention.

[0028] A hydraulic flood discharge gate provided by some embodiments of the utility model will be described below in conjunction with the accompanying drawings.

[0029] Embodiment 1:

[0030] Combination Figure 1-Figure 5 As shown, the utility model provides a hydraulic flood discharge gate, which includes a blocking mechanism 100 and a flood discharge mechanism 200 installed in the blocking mechanism 100 .

[0031] The blocking mechanism 100 includes a horizontal rail 110, a protective outer plate 120, a support frame 130, a beam plate 140, a screw rod 150, a base 160, a cushion 170 and an inclined frame 180, and the flood discharge mechanism 200 includes a gate 210, a baffle 220, a bottom sealing plate 230, a top sealing plate 240, a column 250, a reinforced torsion spring 260, a vertical shaft 270, a winding roller 280 and a steel cable 290.

[0032] Specifically, four protective outer plates 120 are fixedly installed at both ends of the horizontal rail 110, two brackets 130 are installed on the inner sides of two adjacent protective outer plates 120, the beam plate 140 is fixedly installed on the top of the bracket 130, the screw rod 150 is movably installed inside the beam plate 140, the base 160 is located at the bottom of the screw rod 150, the cushion 170 is located in the base 160, the two inclined frames 180 are movably installed on both sides of the base 160, and the two gates 210 are movably installed on the two adjacent protective outer plates 120. On the inner side of the outer plate 120, the baffle 220 is fixedly mounted on the horizontal tube on the inner side of the gate 210, the bottom sealing plate 230 is mounted on the bottom of the gate 210, the top sealing plate 240 is mounted on the top of the gate 210, the column 250 is fixedly mounted on the top of the top sealing plate 240, the reinforcing torsion spring 260 is connected between the top sealing plate 240 and the vertical shaft 270, a plurality of winding rollers 280 are fixedly mounted on the outside of the vertical shaft 270, and the steel cable 290 is wound in the annular groove outside the winding roller 280.

[0033] The horizontal rail 110 and the protective outer plate 120 are pre-buried in the drainage outlet of the reservoir, and then the two gates 210 are movably installed on the inner sides of the two adjacent protective outer plates 120, and then the screw rod 150 is manually adjusted to rotate clockwise. As the bottom end of the screw rod 150 cooperates with the continuous decline of the base 160, the two inclined frames 180 will simultaneously apply outward thrust to the two gates 210 until the two gates 210 open outward. At the moment when the water flow leaks out, the water pressure will press the fishing net against the outside of the multiple steel cables 290. At this time, the two gates 210 in the flood discharge state can provide sufficient compressive bearing capacity for the placed fishing net. At this time, the fishing net in the pressure state can block the fish and shrimp in the reservoir in the flood discharge state.

[0034] Embodiment 2:

[0035] Combination Figure 2-Figure 5 As shown, on the basis of Example 1, the horizontal rail 110 and the protective outer plate 120 are both made of stainless steel material, and two limit rails are fixedly installed on the inner side of the top of the protective outer plate 120, a stainless steel threaded sleeve is fixedly installed in the middle of the beam plate 140, and the screw rod 150 is movably installed inside the stainless steel threaded sleeve, and the inclined frame 180 is composed of two reinforcing steel plates and guide rods fixed on the outer ends of the two reinforcing steel plates.

[0036] By fixing four protective outer plates 120 on the top of both ends of the horizontal rail 110, two adjacent protective outer plates 120 will provide a suitable cavity for the lateral movement of the gate 210, cooperate with the two protective outer plates 120 to position the inner square steel of the gate 210, and use bolts to fix the gasket 170 to the bottom of the screw rod 150. When the top wheel of the screw rod 150 is controlled to rotate, the base 160 assembled at the bottom of the screw rod 150 can apply a uniform downward thrust to the two inclined frames 180, thereby ensuring the consistency of the opening of the two gates 210. As the inclined frame 180 descends, the two gates 210 can expand outward along the slideway on the top of the horizontal rail 110, thereby discharging flood water to the reservoir.

[0037] Embodiment three:

[0038] Combination Figure 4 and Figure 5 As shown, on the basis of Example 1, the gate 210 is welded by square steel and multiple cross tubes, and the top and bottom of the cross tubes are provided with slots adapted to the baffle 220, the top of the bottom sealing plate 230 and the bottom of the top sealing plate 240 are installed with end tubes, and the vertical axis 270 is welded by circular end columns and cross-shaped plug rods.

[0039] By fixing a plurality of baffles 220 on a plurality of transverse tubes, and fixing a bottom sealing plate 230 and a top sealing plate 240 on the bottom and top of the square tube inside the gate 210 respectively with bolts, the two ends of the vertical shaft 270 are movably installed inside the two end tubes, and the two ends of the reinforcing torsion spring 260 are respectively fixed between the vertical shaft 270 and the top sealing plate 240. At this time, the gate 210 and the plurality of baffles 220 in a load-bearing state can move outward along the slideway on the top of the horizontal rail 110 after receiving a thrust. At this time, the plurality of steel cables 290 located in the inner cavity of the two gates 210 will be tightened, thereby providing a sufficiently stable bearing platform for the fishing net. As the gate 210 moves outward laterally, the steel cables 290 can be continuously released from the outside of the winding roller 280. When the gate 210 returns to its initial state, the steel cables 290 will be quickly reset under the torsion of the reinforcing torsion spring 260.

[0040] The working principle and use process of the utility model are as follows: the column 250 is welded to one side of the top of the top sealing plate 240 in advance, and the reinforcing torsion spring 260 is fixedly installed at the bottom of the top sealing plate 240. At this time, the reinforcing torsion spring 260 will be located outside the bottom end tube of the top sealing plate 240. Then, one end of the steel cable 290 is wound in the annular groove outside the winding roller 280, and then the combined multiple winding rollers 280 and the vertical shaft 270 are movably installed in the inner cavity of the gate 210, and the top sealing plate 240 and the bottom sealing plate 230 are fixedly installed on the top and bottom of the gate 210 respectively by bolts. At this time, the top and bottom ends of the vertical shaft 270 respectively penetrate into the end tube at the bottom of the top sealing plate 240 and the end tube at the top of the bottom sealing plate 230, and then the two combined gates 210 are movably installed in the slideway at the top of the horizontal rail 110 until the inner transverse tubes of the two gates 210 are butted, and the other end of the steel cable 290 is passed outward from the inner cavity of another gate 210 until the other end of the steel cable 290 is wound around another set of vertical shafts 270 and the winding roller 280, and is subjected to the torsion force of the strengthening torsion spring 260 on the vertical shaft 270. At this time, the combined steel cable 290 will be tightened on the outside of the two adjacent winding rollers 280;

[0041] During use, as the water level rises, the operator can adjust the wheel on the top of the screw rod 150 to rotate clockwise until the bottom end of the screw rod 150 cooperates with the base 160 to push the two inclined frames 180 downward at the same time, until the two gates 210 move horizontally toward the outside of the horizontal rail 110. At this time, the two adjacent gates 210 will open the gates to discharge flood water, and the multiple steel cables 290 will be tightened in the middle of the two gates 210. At this time, the multiple steel cables 290 that are elastically pulled and tightened can block foreign objects in the flood discharge.

[0042] Although the embodiments of the present invention have been shown and described, those skilled in the art will appreciate that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and purpose of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
