Technical Field

[0001] This utility model relates to the field of water conservancy gate technology for water conservancy projects, specifically a lifting water conservancy gate for water conservancy projects. Background Technology

[0002] Water conservancy projects are engineering projects constructed to mitigate water-related disasters and develop and utilize water resources. They are categorized by their service objectives, including flood control projects, farmland irrigation projects, hydropower projects, waterway and port projects, water supply and drainage projects, environmental water conservancy projects, and coastal reclamation projects. Water conservancy projects that simultaneously serve multiple purposes such as flood control, water supply, irrigation, and power generation are called comprehensive utilization water conservancy projects. Water conservancy projects require the construction of various types of hydraulic structures, such as dams, dikes, spillways, sluice gates, intakes, canals, ferries, raft channels, and fishways, to achieve their objectives.

[0003] During the construction and use of some water conservancy projects, measures are needed to control the flow of water in some diversion channels and tributaries. During the diversion of these tributaries, some garbage in the water will enter the construction area with the water flow, thus affecting the water use of the water conservancy project. In addition, the existing interception nets need to be cleaned regularly, otherwise congestion will occur, thus affecting the efficiency of water flow. Based on this, a lifting water gate for water conservancy projects is proposed. Utility Model Content

The gate body is equipped with side sealing strips, and a bottom sealing strip is fixedly installed at the bottom of the gate body. Sealing recesses are fixedly installed inside both sides of the gate frame. Several side sliding rollers are rolled on both sides of the gate body. Two slide rails are fixedly installed on the front of the gate frame. Two slide bars are slidably installed on the outer sides of the two slide rails. Mounting supports are fixedly installed on the outer sides of the two slide bars. A discharge pipe is fixedly sleeved on the inner side of the mounting support. A servo motor is fixedly installed on the top of the discharge pipe. A spiral transmission rod is driven and connected to the output end of the servo motor. A corrugated pipe is connected to one side of the top of the discharge pipe. A mounting bracket is fixedly installed on the front of the gate body by bolts. A garbage collection filter frame is fixedly installed on the outer side of the mounting bracket by bolts.

[0006] Preferably, the chain passes through the support frame via a through slot and drives sprocket one and sprocket two.

[0007] Preferably, the support frame is fixedly installed on the top of the gate frame, and both ends of the rotating rod are rotatably connected to the opposite side of the support frame through a support shaft seat.

[0008] Preferably, the dimensions of the side sealing strip and the gate body are adapted to the dimensions of the gate frame and the sealing groove. The outer side of the side sliding roller is in rolling contact with the inner side of the gate frame. The side sliding roller passes through the side sealing strip and the sealing groove through the groove and is in rolling contact with the inner wall of the gate frame. The side sliding roller is linearly and uniformly distributed on the opposite sides of the gate body and the gate frame.

[0009] Preferably, bolts penetrate the interior of both ends of the slide bar, the slide bar is fixed to the outside of the slide rail by bolts, and the mounting bracket is fixedly installed on the outside of the slide bar by bolts.

[0010] Preferably, the dimensions of the spiral conveyor rod are adapted to the dimensions of the discharge pipe, the corrugated pipe is inclined downward and connected at the top of the discharge pipe, the back and bottom surfaces of the waste collection filter frame are hollow, and the position of the discharge pipe corresponds to the position of the waste collection filter frame.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: When the device is in use, the gate frame and gate body are closed to intercept the water channel. When it is opened, the winding motor is started to drive the rotating shaft to rotate, which in turn drives the first sprocket to rotate. This drives the second sprocket to rotate through the chain, which in turn drives the rotating rod to rotate. The rotating rod drives the winding roller to rotate, and then the gate body is lifted by the sling, thus opening the water channel and guiding the water flow. When the water flow is guided, the water flows downward through the gap between the gate frame and the gate body. The water flows downward through the garbage collection filter frame. At this time, the debris and garbage in the water flow are intercepted by the garbage collection filter frame. At this time, the servo motor is started to drive the spiral conveyor rod to rotate, and it cooperates with the discharge pipe to form a spiral conveying mechanism, thereby transporting the garbage and debris into the water and guiding the flow through the corrugated pipe at an incline, thereby reducing the number of cleanings and reducing the labor intensity of the operators.

[0012] The sliding rails and sliders facilitate the adjustment of the height of the installation support and discharge pipe, thereby coordinating with the water storage height adjustment to meet the flow guidance requirements of different water channels. This makes it easier to adapt to different flow guidance operations in water channels and ditches of different heights, and overall facilitates the construction and flow guidance of water projects.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figures 1-4 This utility model provides a technical solution: a lifting hydraulic gate for water conservancy projects, including a gate frame 1, a gate body 3 slidably installed on the inner side of the gate frame 1, two lifting cables 4 bolted to the top of the gate body 3, and a winding roller 11 wound around the other end of each lifting cable 4, a rotating rod 12 fixedly sleeved on the inner side of the winding roller 11, a sprocket 2 10 fixedly sleeved on the outer side of the middle part of the rotating rod 12, a chain 8 meshing with the outer side of the sprocket 2 10, a sprocket 1 9 meshing with the inner side of the top end of the chain 8, a rotating shaft 6 fixedly sleeved on the inner side of the sprocket 1 9, bearing brackets 5 movably sleeved on the outer sides of both ends of the rotating shaft 6, a winding motor 7 drivingly connected to one end of the rotating shaft 6, a support frame 2 fixedly installed at the bottom of the winding motor 7, and side sealing strips 13 fixedly installed on both sides of the gate body 3. A bottom sealing strip 23 is fixedly installed at the bottom of the gate body 3. Sealing recesses 24 are fixedly installed inside both sides of the gate frame 1. Several side sliding rollers 25 are rolled on both sides of the gate body 3. Two slide rails 14 are fixedly installed on the front of the gate frame 1. Two slide bars 15 are slidably installed on the outer side of the two slide rails 14. Mounting brackets 19 are fixedly installed on the outer side of the two slide bars 15. A discharge pipe 18 is fixedly sleeved on the inner side of the mounting bracket 19. A servo motor 20 is fixedly installed on the top of the discharge pipe 18. A spiral transmission rod 22 is driven and connected to the output end of the servo motor 20. A corrugated pipe 21 is connected to one side of the top of the discharge pipe 18. A mounting bracket 17 is fixedly installed on the front of the gate body 3 by bolts. A garbage collection filter frame 16 is fixedly installed on the outer side of the mounting bracket 17 by bolts.

[0020] The working principle of the above technical solution is as follows: When in use, the gate frame 1 and gate body 3 close to intercept the installed water channel. When open, the winding motor 7 is started to drive the rotating shaft 6 to rotate, which in turn drives the sprocket 9 to rotate. This drives the chain 8 to drive the sprocket 10 to rotate, which in turn drives the rotating rod 12 to rotate. The rotating rod 12 drives the winding roller 11 to rotate, which in turn pulls up the gate body 3 through the hoisting cable 4, thus opening the water channel for diversion. When the water is diverted, the water flows downward through the gap between the gate frame 1 and gate body 3. The water flows downward through the garbage collection filter frame 16. At this time, the debris and garbage in the water flow are intercepted by the garbage collection filter frame 16. At this time, the servo motor 20 is started to rotate, which drives the spiral conveyor rod 22 to rotate. It cooperates with the discharge pipe 18 to form a spiral conveying mechanism, thereby transporting the garbage and debris into the water and tilting back through the corrugated pipe 21, thereby reducing the number of cleanings and reducing the labor intensity of the operators.

[0021] In another implementation scheme, such as Figure 1 and Figure 2 As shown, chain 8 passes through support frame 2 via through groove and drives sprocket 1 9 and sprocket 2 10.

[0022] Chain 8 transmits power through sprocket 9 and sprocket 10, facilitating transmission.

[0023] In another implementation scheme, such as Figures 1-3 As shown, the support frame 2 is fixedly installed on the top of the gate frame 1, and both ends of the rotating rod 12 are rotatably connected to the opposite side of the support frame 2 through the support shaft seat.

[0024] The support frame 2 provides installation positions for the bearing bracket 5, the rotating shaft 6 and the winding motor 7, and provides support for the rotating rod 12. The rotating rod 12 is rotated and supported inside the support frame 2 through the bearing support, thereby ensuring the rotation effect of the rotating rod 12 and facilitating the operation of the structure.

[0025] In another implementation scheme, such as Figures 1-4 As shown, the dimensions of the side sealing strip 13 and the gate body 3 are compatible with the dimensions of the gate frame 1 and the sealing recess 24. The outer side of the side sliding roller 25 rolls in contact with the inner side of the gate frame 1. The side sliding roller 25 passes through the groove through the side sealing strip 13 and the sealing recess 24 and rolls in contact with the inner wall of the gate frame 1. The side sliding roller 25 is linearly and uniformly distributed on the opposite sides of the gate body 3 and the gate frame 1.

[0026] The side sealing strip 13 and the sealing recess 24 provide flexible sealing to the gate frame 1 and the gate body 3, reducing the flow of water and thus improving the sealing effect. The fixed part of the side sliding roller 25 is fixed to the outside of the gate body 3, and the roller part of the side sliding roller 25 rolls against the inside of the gate frame 1, which facilitates stable positioning, reduces friction, and facilitates stable operation between the gate body 3 and the gate frame 1. The side sliding roller 25 is installed through the slot holes opened on the inside of the side sealing strip 13 and the sealing recess 24, so as to ensure stable operation of the structure without affecting the sealing effect.

[0027] In another implementation scheme, such as Figures 1-4 As shown, bolts pass through the interior of both ends of the slide bar 15. The slide bar 15 is fixed to the outside of the slide rail 14 by bolts, and the mounting bracket 19 is fixed to the outside of the slide bar 15 by bolts.

[0028] The sliding rails 14 and 15 facilitate the adjustment of the height of the mounting bracket 19 and the discharge pipe 18, thereby coordinating with the water storage height adjustment to accommodate different water storage conditions in different canals. This makes it easier to adapt to different water diversion operations in canals and ditches of varying heights, thus facilitating the construction and water diversion of water conservancy projects. Bolt holes are provided on the side of the sliding rails 14, as well as on the front of the sliding rails 15 and the mounting bracket 17, allowing for easy installation, fixing, and position adjustment of the mounting bracket 19 and the garbage collection filter frame 16. This facilitates installation at different water storage heights, thereby increasing the ease of use of the structure.

[0029] In another implementation scheme, such as Figures 1-3 As shown, the dimensions of the spiral conveyor 22 are compatible with those of the discharge pipe 18. The corrugated pipe 21 is inclined downward and connected to the top of the discharge pipe 18. The back and bottom surfaces of the garbage collection filter frame 16 are hollow. The position of the discharge pipe 18 corresponds to the position of the garbage collection filter frame 16.

[0030] The spiral conveyor rod 22 and the discharge pipe 18 form a spiral conveying structure, which facilitates the transmission of debris. The servo motor 20 provides a transmission function for the spiral conveyor rod 22, making it convenient to operate and easy to cooperate with the garbage collection filter frame 16 for stable transmission.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
