Description

Technical Field

[0001] This utility model relates to the field of water conservancy engineering equipment technology, specifically to a water conservancy engineering diversion device. Background Technology

[0002] In the field of water conservancy engineering, river diversion is a common operational scenario, achieving effects such as flood control and discharge, water resource allocation, and irrigation water supply. For example, during the flood season, it is necessary to divert part of the water flow from the main river to a diversion channel to reduce the pressure on the main river, or during the irrigation season, it is necessary to rationally allocate the river flow.

[0003] In existing technologies, river diversion is usually achieved through simple gate structures, which can only control the flow of water on and off, but cannot agitate the diverted water. This can easily lead to uneven flow velocity within the diversion channel, and even localized siltation. At the same time, debris such as branches, garbage, and stones carried by the water can easily enter the diversion channel directly.

[0004] Therefore, a water diversion device for water conservancy projects is proposed. Utility Model Content

[0005] The purpose of this utility model is to provide a water diversion device for water conservancy projects in order to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model specifically adopts the following technical solution:

[0007] A water diversion device for a water conservancy project includes a main channel, a diversion channel, and a connecting frame. A gate diversion assembly is installed on the diversion channel to control water flow and regulate flow. A lifting assembly is installed on the top surface of the diversion channel for raising and lowering the connecting frame, allowing it to move up and down within the channel. An agitator is installed on the connecting frame to agitate the diverted water flow and prevent siltation. A counterweight is fixedly connected to the bottom surface of the inner wall of the connecting frame, allowing it to move downwards. A guide and stabilizing assembly is installed on the inner wall of the diversion channel to maintain the stability of the connecting frame. A barrier net is fixedly connected to the surface of the connecting frame to block debris in the water flow.

[0008] Furthermore, the gate diversion assembly includes a support frame, which is fixedly connected to the top surface of the diversion channel. A screw-type opening and closing mechanism is mounted on the support frame, and a gate plate is mounted on the screw-type opening and closing mechanism. The screw-type opening and closing mechanism allows for precise adjustment of the gate plate's lifting height, thereby controlling the water flow rate of the diversion channel.

[0009] Furthermore, the lifting assembly includes a connecting block, which is fixedly connected to the top surface of the diversion channel. A motor is mounted on the connecting block, and a rotating rod is fixedly connected to the output end of the motor. The rotating rod is rotatably connected to the connecting block, and a rope roller is fixedly sleeved on the surface of the rotating rod. The rope end of the rope roller is fixedly connected to the connecting frame. The motor drives the rotating rod to rotate, causing the rope roller to retract and extend the rope, thereby lifting the connecting frame and raising the barrier net to clear the blocked debris.

[0010] Furthermore, the agitation assembly includes a second motor, which is mounted on the connecting frame. A connecting rod is fixedly connected to the output end of the second motor, and the connecting rod is rotatably connected to the connecting frame. Agitator blades are fixedly attached to the surface of the connecting rod. The second motor drives the connecting rod to rotate, causing the agitator blades to rotate and agitate the water flow in the diversion channel, ensuring a uniform water flow velocity and preventing siltation.

[0011] Furthermore, the guiding and stabilizing component includes a guide groove, which is formed on the inner wall of the diversion channel. A guide block is slidably connected to the inner wall of the guide groove, and the guide block is fixedly connected to the connecting frame. When the connecting frame is raised or lowered, the guide block slides along the guide groove, providing guidance and stabilization for the connecting frame and preventing it from shifting.

[0012] Furthermore, the barrier net is made of metal, and its surface is fitted to the inner wall of the diversion channel. The metal material ensures the strength of the barrier net, and its design of fitting snugly against the inner wall of the diversion channel effectively blocks debris such as branches and garbage from the water flow.

[0013] The beneficial effects of this utility model are as follows:

[0014] This invention utilizes a stirring component that, through a motor-driven linkage and stirring blades, rotates at high speed to effectively disturb the water flow within the diversion channel. This promotes uniform water flow velocity, reduces the accumulation of silt and sediment, and ensures unobstructed diversion channels. The metal barrier netting fits tightly against the inner wall of the diversion channel, forming a full-section interception structure. This effectively blocks debris such as branches, garbage, and stones from the water flow, preventing blockage of the diversion channel and damage to subsequent components. Furthermore, the stable, non-floating, and non-shaking connecting frame ensures that the netting remains firmly attached to the inner wall of the channel, further enhancing the reliability of the interception.

[0015] 2. The lifting assembly achieves the lifting and lowering of the connecting frame through the cooperation of motor 1, rotating rod and rope roller. The guide groove and guide block of the guide stabilizing assembly limit lateral deviation. The counterweight uses gravity to balance the weight of the connecting frame, which not only prevents the connecting frame from floating and swaying from side to side, but also reduces the load on motor 1, making the lifting process smooth and stable. After the connecting frame is raised, the debris on the barrier cover can be directly exposed, which is convenient for staff to clean up quickly, greatly improving maintenance efficiency and reducing maintenance labor intensity.

[0025] like Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, a water diversion device for a water conservancy project includes a main channel 1, a diversion channel 2, and a connecting frame 4. A gate diversion component 3 is installed on the diversion channel 2, a lifting component 5 for raising and lowering the connecting frame 4 is installed on the top surface of the diversion channel 2, an agitation component 6 is installed on the connecting frame 4, a counterweight 7 is fixedly connected to the bottom surface of the inner wall of the connecting frame 4, a guide stabilizing component 8 is installed on the inner wall of the diversion channel 2, and a blocking net 9 is fixedly connected to the surface of the connecting frame 4. Specifically, the main channel 1 and the diversion channel 2 are connected in a continuous manner, and the inlet end of the diversion channel 2 is connected to the side wall of the main channel 1. The connecting frame 4 is a rectangular frame structure, and the counterweight 7 is made of high-density material and is detachably connected to the bottom surface of the inner wall of the connecting frame 4 by bolts to ensure the gravity balance of the connecting frame 4 and prevent it from floating or tilting in the water flow.

[0026] like Figure 1 , Figure 2 As shown, the gate diversion assembly 3 includes a bracket 301, which is fixedly connected to the top surface of the diversion channel 2. A screw-type opening and closing mechanism 302 is installed on the bracket 301, and a gate plate 303 is installed on the screw-type opening and closing mechanism 302. Specifically, the bracket 301 is a portal steel structure, which is fixed to both sides of the top surface of the diversion channel 2 by pre-embedded bolts. The screw-type opening and closing mechanism 302 includes a drive motor, a reduction gearbox, a screw, and a nut seat. The nut seat is fixed to the middle of the crossbeam of the bracket 301. The screw passes through the nut seat and is fixedly connected to the center of the top surface of the gate plate 303. The outline of the gate plate 303 matches the inlet section of the diversion channel 2, and wear-resistant sealing parts are provided on both sides of its edges, which can fit tightly with the inner wall of the gate slot of the diversion channel 2 to improve the sealing performance.

[0027] like Figure 2 , Figure 3As shown, the lifting assembly 5 includes a connecting block 501. The connecting block 501 is fixedly connected to the top surface of the diversion channel 2. A motor 502 is installed on the connecting block 501. A rotating rod 503 is fixedly connected to the output end of the motor 502, and the rotating rod 503 is rotatably connected to the connecting block 501. A rope roller 504 is fixedly sleeved on the surface of the rotating rod 503, and the rope end of the rope roller 504 is fixedly connected to the connecting frame 4. Specifically, there are two connecting blocks 501, which are symmetrically fixed on both sides of the top surface of the diversion channel 2. The motor 502 is fixed to the side of the connecting block 501 by bolts. The two ends of the rotating rod 503 are rotatably connected to the two connecting blocks 501 by bearings. There are two rope rollers 504, which are symmetrically sleeved on the surface of the rotating rod 503. The rope is made of high-strength corrosion-resistant material. One end of the rope is fixed to the rope roller 504, and the other end is fixedly connected to the lifting lugs on both sides of the top surface of the connecting frame 4 to ensure that the connecting frame 4 is subjected to balanced force when it is raised and lowered.

[0028] like Figure 3 , Figure 4 As shown, the agitation component 6 includes a second motor 601, which is mounted on the connecting frame 4. The output end of the second motor 601 is fixedly connected to a connecting rod 602, and the connecting rod 602 is rotatably connected to the connecting frame 4. Agitation blades 603 are fixedly connected to the surface of the connecting rod 602. Specifically, the second motor 601 is fixed to the middle of the top surface of the connecting frame 4 by a waterproof mounting base. The connecting rod 602 is made of corrosion-resistant metal, and one end is fixed to the output end of the second motor 601 by a coupling and rotatably connected to the connecting frame 4 by a waterproof bearing. There are multiple agitation blades 603, which are evenly fixed on the surface of the connecting rod 602. The high-speed rotation of the agitation blades 603 disturbs the water flow in the diversion channel 2, making the water flow velocity uniform and preventing the accumulation of silt and sediment.

[0029] like Figure 3 As shown, the guiding and stabilizing component 8 includes a guide groove 801. The inner wall of the diversion channel 2 is provided with the guide groove 801. A guide block 802 is slidably connected to the inner wall of the guide groove 801, and the guide block 802 is fixedly connected to the connecting frame 4. Specifically, the guide groove 801 is a rectangular groove, and there are two of them, which are symmetrically opened on both sides of the inner wall of the diversion channel 2. The length of the guide groove 801 is adapted to the depth of the diversion channel 2. The guide block 802 is a rectangular block structure made of wear-resistant material and is fixed to the connecting frame 4 by bolts. The guide block 802 and the inner wall of the guide groove 801 are fitted with a clearance to ensure smooth sliding and no obvious shaking.

[0030] like Figure 2As shown, the barrier net 9 is made of metal, and the surface of the barrier net 9 is attached to the inner wall of the diversion channel 2. Specifically, the barrier net 9 is made of corrosion-resistant metal to ensure its structural strength. The mesh size can effectively intercept debris such as leaves without affecting the flow of water. The edge of the barrier net 9 is fixedly connected to the outer periphery of the connecting frame 4, and its outer surface is attached to the inner wall of the diversion channel 2, thereby effectively blocking debris.

[0031] In summary: When the gate diversion component 3 is working, the screw-type opening and closing mechanism 302 on the bracket 301 converts rotational motion into linear motion through the meshing transmission of the screw and nut, precisely driving the gate plate 303 to rise and fall, thereby achieving the interruption of water flow between the diversion channel 2 and the main channel 1. Simultaneously, by adjusting the rising and falling height of the gate plate 303, stepless control of the diversion flow rate is achieved to meet the needs of different diversion scenarios. The blocking mesh 9 fixed to the surface of the connecting frame 4 is made of metal and fits tightly against the inner wall of the diversion channel 2, forming a full-section interception structure, effectively blocking debris such as branches, garbage, and stones in the water flow, preventing debris from clogging the diversion channel 2 or damaging subsequent components. After the stirring component 6 is started, the motor 601 on the connecting frame 4 drives the connecting rod 602 to rotate. The connecting rod 602 drives the surface-fixed stirring blades 603 to rotate at high speed, disturbing the water flow in the diversion channel 2, making the water flow velocity uniform, and preventing... Silt and sediment accumulate; when it is necessary to clean debris from the barrier net 9, the motor 502 of the lifting component 5 starts, driving the rotating rod 503 and the rope roller 504 to wind up the rope. The tension of the rope drives the connecting frame 4 to rise. During this process, the guide block 802 on the connecting frame 4 slides along the guide groove 801 on the inner wall of the diversion channel 2, limiting lateral deviation and ensuring accurate lifting trajectory. After cleaning, the motor 502 reverses, the rope roller 504 releases the rope, and the counterweight 7 on the bottom of the inner wall of the connecting frame 4 uses its gravity to make the connecting frame 4 descend smoothly and reset, while the connecting frame 4 does not float. The setting of the guide stabilizing component 8 can also prevent the connecting frame 4 from swaying left and right due to water flow impact. The connecting frame 4 does not float or sway, ensuring the fit between the barrier net 9 and the inner wall of the channel, while reducing the load on the motor 502, making the lifting process smoother. All components work together to complete the closed-loop operation of diversion, protection, silt prevention and maintenance.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
