Description

Technical Field

[0001] This utility model belongs to the field of water conservancy facilities technology, specifically relating to a channel water diversion gate structure. Background Technology

[0002] In scenarios such as agricultural irrigation, urban water supply, and ecological water replenishment, the rational allocation of water resources is the foundation for ensuring the water demand of various regions. The water from natural water systems or artificial channels often needs to be diverted according to the water consumption of different regions (such as different farmland areas or different tributary channels), and the water diversion gate is the core structure to achieve this function.

[0003] Traditional water diversion gates mostly adopt a single gate synchronous control of multiple diversion outlets design, with the flow of all diversion outlets being tied together for regulation. They cannot be individually adjusted according to downstream water demand (such as different farmlands or pipe networks). When the downstream water demand of different diversion outlets differs greatly (such as dry land and paddy fields, high water-consuming crops and low water-consuming crops), some areas will experience oversupply, leading to waterlogging and secondary soil salinization, or some areas will experience undersupply, resulting in crop drought and reduced yields, insufficient industrial or domestic water use, and extremely low water resource utilization. Especially in water-scarce areas, the oversupply is directly wasted, exacerbating water resource tension.

[0004] Therefore, a channel diversion gate structure was designed to solve the above problems. Utility Model Content

[0005] To address the problems mentioned in the background art, this utility model provides a channel water diversion gate structure. Using this device, four independently adjustable diversion ports can flexibly cope with the differences in water usage in different scenarios, and the opening of each group of gates does not interfere with each other. It can achieve differentiated flow distribution according to the actual water demand of different diversion directions without the need to adjust all gates in a coordinated manner, and can quickly respond to sudden demands, thus improving the applicability of the equipment.

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

[0007] A channel diversion gate structure includes a gate body cylinder and a fixed diversion port formed on the surface of the gate body cylinder. The surface of the gate body cylinder is provided with an adjusting gate. The inner surface of the gate body cylinder is provided with a gate sliding groove that cooperates with the adjusting gate. A guide connecting block is fixedly connected to the top of the adjusting gate. The surface of the gate body cylinder is provided with a guide limiting groove that cooperates with the guide connecting block. A gate adjusting block is fixedly connected to the surface of the guide connecting block. The surface of the gate body cylinder is provided with an adjusting block sliding groove that cooperates with the gate adjusting block.

[0008] As a preferred embodiment of the channel diversion gate structure of this utility model, four sets of fixed diversion ports are provided, and the four sets of fixed diversion ports are evenly opened on the surface of the gate body cylinder.

[0009] As a preferred embodiment of the channel water diversion gate structure of this utility model, the regulating gate is an arc-shaped plate structure, the curvature of which is adapted to the curvature of the gate sliding groove opened inside the gate body.

[0010] As a preferred embodiment of the channel diversion gate structure of this utility model, the top of the regulating gate is symmetrically provided with locking blocks, the surface of the regulating gate is provided with a block avoidance groove that cooperates with the locking blocks, the opposite side of the locking blocks is provided with an elastic connection groove, the opposite side of the locking blocks is provided with a locking spring, the locking spring is fixedly connected to the locking blocks through the elastic connection groove, and the surface of the gate body is provided with a block positioning groove that cooperates with the locking blocks.

[0011] As a preferred embodiment of the channel diversion gate structure of this utility model, five sets of locking blocks, blocking block clearance grooves, elastic connecting grooves and locking springs are provided. The five sets of locking blocks, blocking block clearance grooves, elastic connecting grooves and locking springs are evenly arranged at the top of the regulating gate, and several sets of blocking block positioning grooves are provided.

[0012] As a preferred embodiment of the channel water diversion gate structure of this utility model, the top of the regulating gate is fixedly connected to a limiting groove sealing plate, and the surface of the gate body is provided with a sealing plate groove that cooperates with the limiting groove sealing plate.

[0013] As a preferred embodiment of the channel water diversion gate structure of this utility model, the top of the gate body cylinder is engraved with angle scale lines, and the surface of the guide connecting block is engraved with angle indicator arrows.

[0014] Compared with existing technologies, the advantages of this utility model are as follows: Four independently adjustable diversion ports can flexibly address water usage differences in various scenarios, and the opening degree of each gate does not interfere with each other. Differential flow distribution can be achieved according to the actual water demand in different diversion directions without the need for coordinated adjustment of all gates. This allows for rapid response to sudden demands, improving equipment applicability. Furthermore, the matching design of the arc-shaped adjusting gate and sliding groove, combined with several densely distributed locking block positioning slots, enables precise adjustment of the gate at small angles. Simultaneously, the mechanical locking structure of the locking block and spring firmly fixes the gate position, preventing displacement caused by water flow impact and vibration. This solves the problems of low adjustment accuracy and easy loosening due to external forces in traditional equipment, ensuring long-term stability after flow adjustment and avoiding the impact of flow fluctuations on water usage.

[0025] 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.

[0026] Example 1

[0027] In this implementation plan: Traditional water diversion gates mostly use a single gate to synchronously control multiple diversion outlets. The flow rates of all diversion outlets are adjusted in a bundled manner, and it is impossible to adjust them individually according to the downstream water demand (such as different farmlands or pipe networks). When the downstream water demand of different diversion outlets varies greatly (such as dry land and paddy fields, high water-consuming crops and low water-consuming crops), some areas will experience oversupply, which will lead to waterlogging and secondary soil salinization, or some areas will experience undersupply, resulting in crop drought and reduced yields, insufficient industrial or domestic water use, and extremely low water resource utilization. Especially in water-scarce areas, the oversupply is directly wasted, exacerbating water resource tension. In terms of combined use, this problem is obviously a real and difficult problem to solve.

[0028] Furthermore:

[0029] This application incorporates the aforementioned prior art, such as Figures 1 to 7 As shown:

[0030] Based on the above: A channel diversion gate structure includes a gate body cylinder 1 and a fixed diversion port 2 opened on the surface of the gate body cylinder 1. An regulating gate 3 is provided on the surface of the gate body cylinder 1. A gate sliding groove 31 that cooperates with the regulating gate 3 is opened on the inner surface of the gate body cylinder 1. A guide connecting block 32 is fixedly connected to the top of the regulating gate 3. A guide limiting groove 33 that cooperates with the guide connecting block 32 is opened on the surface of the gate body cylinder 1. A gate regulating block 34 is fixedly connected to the surface of the guide connecting block 32. An regulating block sliding groove 35 that cooperates with the gate regulating block 34 is opened on the surface of the gate body cylinder 1.

[0031] In this implementation scheme: the gate body cylinder 1 serves as the core support, the fixed diversion port 2 is the water flow output channel, the regulating gate 3 is embedded in the gate sliding groove 31 of the gate body cylinder 1 and slides along the arc groove, the guide connecting block 32 moves synchronously and is constrained by the guide limiting groove 33 to ensure that the regulating gate 3 only moves along the preset trajectory. When the gate regulating block 34 is operated, it is displaced in the regulating block sliding groove 35, and drives the regulating gate 3 to slide through the guide connecting block 32, thereby changing the blocking area of ​​the fixed diversion port 2 and realizing flow regulation.

[0032] Furthermore:

[0033] like Figures 1 to 7 As shown:

[0034] In an optional embodiment, four sets of fixed diversion ports 2 are provided, and the four sets of fixed diversion ports 2 are evenly opened on the surface of the gate body cylinder 1.

[0035] In this embodiment, four sets of fixed diversion ports 2 are equidistantly distributed along the circumference of the gate body cylinder 1. Water flows through the inside of the gate body cylinder 1 and is evenly distributed in four directions by adjusting the blocking ratio of the gate 3. Furthermore, the regulating gate 3 corresponding to the four sets of fixed diversion ports 2 can be adjusted independently to achieve "on-demand water distribution," avoiding the "oversupply" or "undersupply" problems caused by traditional synchronous regulation, improving water resource utilization, and flexibly responding to dynamic scenarios (such as flood discharge during the flood season, water conservation during the drought season, and time-sharing water use). Only the regulating gate 3 of the target diversion port needs to be adjusted, without the need to link other channels, and quickly responding to sudden demands.

[0036] Furthermore:

[0037] like Figure 7 As shown:

[0038] In an optional embodiment, the regulating gate 3 is an arc-shaped plate structure, the curvature of which is adapted to the curvature of the gate sliding groove 31 opened in the gate body cylinder 1.

[0039] In this embodiment, the regulating gate 3 is an arc-shaped plate, and its curvature is perfectly matched with the curvature of the gate sliding groove 31 inside the gate body cylinder 1. When sliding, the outer arc surface of the regulating gate 3 is tightly fitted with the inner wall of the gate body cylinder 1, and the inner arc surface moves smoothly along the gate sliding groove 31. This not only improves the sealing performance and reduces water leakage, but also reduces the sliding friction resistance and extends the service life of the regulating gate 3. The arc structure can also disperse the impact force of water flow and enhance the deformation resistance of the regulating gate 3.

[0040] Furthermore:

[0041] like Figure 4 and Figure 5 As shown:

[0042] In an optional embodiment, locking blocks 4 are symmetrically arranged at the top of the regulating gate 3. The surface of the regulating gate 3 is provided with a block clearance groove 41 that cooperates with the locking blocks 4. An elastic connecting groove 42 is provided on the opposite side of the locking blocks 4. A locking spring 43 is provided on the opposite side of the locking blocks 4. The locking spring 43 is fixedly connected to the locking blocks 4 through the elastic connecting groove 42. The surface of the gate body cylinder 1 is provided with a block positioning groove 44 that cooperates with the locking blocks 4.

[0043] In this embodiment: when the regulating gate 3 moves to the target position, the locking spring 43 extends along the elastic connecting groove 42, pushes the locking block 4 out of the block clearance groove 41, and embeds into the block positioning groove 44 of the gate body cylinder 1, thereby locking the position of the regulating gate 3. When an external force is applied to press the locking block 4, it compresses the locking spring 43, causing it to return to the block clearance groove 41. After the lock is released, the regulating gate 3 can slide again. The mechanical locking structure prevents the regulating gate 3 from being displaced due to water flow impact or vibration, ensuring the stability after flow regulation. The spring-driven block design combines locking reliability with convenient operation, requiring no additional tools for unlocking.

[0044] Furthermore:

[0045] like Figure 4 and Figure 5 As shown:

[0046] In an optional embodiment, five sets of locking blocks 4, block clearance grooves 41, elastic connecting grooves 42 and locking springs 43 are provided. The five sets of locking blocks 4, block clearance grooves 41, elastic connecting grooves 42 and locking springs 43 are evenly arranged at the top of the regulating gate 3, and several sets of block positioning grooves 44 are provided.

[0047] In this embodiment, five sets of locking blocks 4, block clearance grooves 41, elastic connecting grooves 42, and locking springs 43 are equidistantly distributed along the top of the regulating gate 3, and participate in the locking / unlocking action simultaneously. When locking, the five sets of locking blocks 4 simultaneously engage with the corresponding block positioning grooves 44. When unlocking, the five sets of locking blocks 4 retract simultaneously. Several sets of block positioning grooves 44 are densely distributed along the movement trajectory of the regulating gate 3. The distance between two adjacent sets of grooves corresponds to the small angle difference of the regulating gate 3. When the regulating gate 3 moves, the locking blocks 4, under the action of the locking springs 43, can quickly engage with the nearest block positioning groove 44 with the small displacement of the regulating gate 3, forming a stepped adjustment mechanism that can stably lock with each small angle movement. This dense distribution makes the angle change of the regulating gate 3 no longer a continuous and unrestrained sliding, but a controllable and fine adjustment achieved through small step locking.

[0048] Furthermore:

[0049] like Figure 6 As shown:

[0050] In an optional embodiment, a limiting groove sealing plate 5 is fixedly connected to the top of the regulating gate 3, and a sealing plate groove 51 that cooperates with the limiting groove sealing plate 5 is opened on the surface of the gate body cylinder 1.

[0051] In this embodiment: the limiting groove sealing plate 5 moves synchronously with the regulating gate 3 and slides along the sealing plate groove 51 on the surface of the gate body cylinder 1, continuously blocking the opening of the guide limiting groove 33, preventing mud, sand and debris from entering the groove, and preventing internal water from overflowing. The dynamic sealing design isolates external impurities and avoids problems such as jamming and wear of the regulating gate 3 caused by scale accumulation in the groove. The cooperation between the limiting groove sealing plate 5 and the sealing plate groove 51 also improves the overall appearance of the gate body and reduces the maintenance frequency.

[0052] Furthermore:

[0053] like Figure 2 As shown:

[0054] In an optional embodiment, the top of the gate cylinder 1 is engraved with an angle scale line 6, and the surface of the guide connecting block 32 is engraved with an angle indicator arrow 61.

[0055] In this embodiment: when the regulating gate 3 rotates or slides, the angle indicator arrow 61 on the surface of the guide connecting block 32 moves along the angle scale line 6 at the top of the gate body cylinder 1, intuitively displaying the ratio of the rotation angle of the regulating gate 3 to the exposed area of ​​the fixed diversion port 2. The visual angle indicator simplifies the manual operation process, improves the flow regulation accuracy, and avoids the error of adjustment based on experience. The combination of scale and arrow also provides an intuitive manual verification basis for automated control.

[0056] Working principle: When the equipment is in the unadjusted state, the regulating gate 3 completely blocks and fixes the diversion port 2. The locking block 4, under the action of the locking spring 43, is locked into the initial position of the locking block positioning groove 44. The angle indicator arrow 61 is aligned with the initial zero position of the angle scale line 6. Adjustment is started directly by operating the gate regulating block 34. When the hand or drive device acts on the gate regulating block 34, the locking block 4 is indirectly squeezed by external force. The locking spring 43 is compressed along the elastic connecting groove 42, which drives the locking block 4 to retract into the locking block avoidance groove 41, releasing the lock with the locking block positioning groove 44. This pushes the gate regulating block 34, causing it to move along the regulating block sliding groove 35. Through the transmission of the guide connecting block 32, the regulating gate 3 slides in the gate sliding groove 31. At the same time, the guide connecting block 32 moves synchronously along the guide limiting groove 33, constraining the regulating gate 3 to move only along the arc trajectory to avoid deviation. When the regulating gate 3 slides, the sealing plate 5 of the limiting groove at the top moves accordingly. It moves synchronously along the sealing plate groove 51, always blocking the guide limit groove 33 to prevent impurities from entering and water from overflowing. The angle indicator arrow 61 on the surface of the guide connecting block 32 moves with the gate and slides along the angle scale line 6 at the top of the gate body cylinder 1, displaying the rotation angle of the regulating gate 3 in real time, corresponding to the exposed area of ​​the fixed diversion port 2. When the angle indicator arrow 61 is aligned with the target scale, that is, when the fixed diversion port 2 reaches the required exposed area, the locking spring 43 loses the external force constraint, extends along the elastic connecting groove 42, pushes the locking block 4 out of the block avoidance groove 41, and locks into the corresponding block positioning groove 44, fixing the regulating gate 3 in the current position to avoid displacement caused by water flow impact. The above process is repeated to operate the regulating gate 3 corresponding to the other three groups of fixed diversion ports 2 respectively. The adjustment of each group of regulating gate 3 does not interfere with each other. By independently controlling the movement of the gate regulating block 34, the differentiated flow distribution of the four groups of diversion ports is realized.

[0057] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
