Description

Technical Field

[0001] This utility model relates to the field of flood control equipment technology, and in particular to a diversion device for flood control and river management. Background Technology

[0002] In water conservancy projects, especially in the fields of flood control and river management, diversion devices are one of the most important infrastructures. Their main function is to guide the surging water flow to a predetermined, safer river channel or area by changing the original path or shape of the water flow, thereby reducing the direct impact of the water flow on dikes, riverbanks or important facilities and effectively reducing the risk of flood disasters.

[0003] Currently, most of the flood control and river diversion devices widely used are fixed structures, such as diversion channels formed by precast concrete components or metal plates with fixed angles. When designing these devices, the diversion diameter and guiding angle are determined based on historical hydrological data or estimated peak flow. Once construction is completed, their structure and diversion capacity are fixed.

[0004] However, natural flood processes are highly uncertain and dynamic. The flow rate and velocity of floods are not constant values, but fluctuate in real time with factors such as rainfall and upstream water conditions. Traditional fixed diversion devices are severely inadequate in adapting to such changes. When the actual flood flow is less than the design value, the excessively large diversion diameter cannot effectively slow down and buffer the flow. When the flood intensity exceeds expectations, the fixed diversion port will back up water due to insufficient flow capacity, increasing local flood control pressure. It may even become ineffective due to the inability to adjust its structure, making it difficult to achieve the optimal flood control effect in complex actual working conditions and lacking flexibility.

[0005] Therefore, this utility model proposes a diversion device for flood control and river management to overcome the shortcomings of the prior art. Utility Model Content

[0006] In view of the problems of existing flood control and river management diversion devices, such as fixed structure making it difficult to adjust the diversion rate according to flood intensity and complex and time-consuming installation, this utility model aims to provide a flood control and river management diversion device with an improved structure that can effectively solve the above problems.

[0007] This utility model provides a flow guiding device for flood control and river management, including: a tool body, a rotating plate and a rotating shaft; the tool body is provided with a flow guiding groove, the rotating plate is rotatably disposed inside the flow guiding groove, and the rotating shaft is rotatably connected to the tool body and fixedly connected to the rotating plate; the device also includes a support rod, a sliding rod and a protruding rod; wherein, the support rod is fixedly connected to the tool body, the sliding rod is slidably sleeved on the outer wall of the support rod, and the inner wall of the sliding rod is provided with a protruding groove; Preferably, a protruding rod is fixedly connected to the rotating shaft, and the protruding rod slides within the groove. With this structural combination, when the operator pushes or pulls the sliding rod to make it reciprocate along the axial direction of the support rod, the protruding rod will drive the rotating shaft to rotate under the guidance of the groove, thereby causing the rotating plate fixed to the rotating shaft to rotate synchronously, thus changing the cross-sectional size of the water flow through the guide channel and realizing flow regulation.

[0008] Preferably, in order to reliably lock the rotating plate after adjustment and prevent it from moving due to water flow impact, at least a limiting groove is provided on the outer periphery of the rotating shaft; the device also includes a fixing plate and a limiting rod; the fixing plate is fixed to the tool body and has a through hole, and the limiting rod can be inserted and removed through the through hole of the fixing plate and selectively engage or disengage with the limiting groove on the rotating shaft, thereby realizing the locking and unlocking of the rotating shaft.

[0009] Preferably, to enable rapid installation and modular connection of the device at the emergency site, the device also includes a fixing mechanism; the fixing mechanism includes a fixing block with a first mounting groove, in which the tool body is detachably installed; a sliding groove is provided on one side of the tool body, and a second mounting groove is provided on the other side; the fixing mechanism also includes a sliding block, screws, and washers; when two tool bodies need to be connected, the sliding block can slide along the sliding groove of the tool body and enter the second mounting groove of the adjacent tool body to form a snap-fit ​​engagement; subsequently, the screw passes through the washer and is threadedly connected to the tool body, and abuts against the sliding block, firmly locking the sliding block, thereby completing the stable splicing between multiple device units.

[0010] Preferably, as a specific implementation, in order to more smoothly and efficiently convert the linear motion of the sliding rod into the rotational motion of the rotating shaft, the groove on the inner wall of the sliding rod is a helical groove extending along the axial direction of the sliding rod, and the end of the protrusion slides into the helical groove. This design makes the push-pull operation more labor-saving and the transmission process smoother.

[0011] This utility model has the following beneficial effects: 1.

It achieves the ability to easily adjust the flow rate to adapt to floods of different intensities, thereby improving the safety of flood control and the flexibility of operation.

[0012] 2. This utility model, by setting a fixing mechanism consisting of a fixing block, a first mounting groove, a sliding groove, a second mounting groove, a sliding block, screws, and washers, solves the problems of complex and time-consuming installation process and slow emergency response speed of existing flood control devices. It achieves the technical effects of realizing rapid installation and unit connection of the device, shortening the on-site deployment time, improving the emergency response speed, and facilitating transportation and storage.

[0013] 3. This utility model solves the problem that the adjusted guide plate is prone to positional deviation under the impact of water flow, leading to adjustment failure, by setting a limiting rod, a limiting groove and a fixing plate. It achieves the technical effect of reliably locking the rotating plate at any adjustment angle and ensuring the stability of flow control under complex working conditions.

The rotating plate 4 is fixedly connected to a rotating shaft 5, which is rotatably connected to the tool body 1. The rotating plate 4 is used to rotate within the diversion groove 3 to change the size of the water flow path, thereby adjusting the water flow rate.

[0018] The technical solution of this embodiment is that the flood control and river management diversion device also includes a support rod 9, which is fixedly connected to the tool body 1. Furthermore, the device also includes a sliding rod 10 that slides with the support rod 9, and a specific structural fit and connection relationship is formed between the sliding rod 10 and the rotating shaft 5. Please refer to Figure 1 and Figure 4 The support rod 9 is fixedly connected to the tool body 1, and the sliding rod 10 is slidably sleeved on the outer wall of the support rod 9. The inner wall of the sliding rod 10 is provided with a groove 11. In a specific embodiment, the groove 11 is a spiral groove extending along the axial direction of the sliding rod 10. A corresponding protrusion 12 is fixedly connected to the rotating shaft 5. In the assembled state, the end of the protrusion 12 is slidably engaged in the groove 11 of the sliding rod 10, which can make the sliding rod 10 slide linearly along the axial direction of the support rod 9, efficiently converting it into the rotational motion of the rotating shaft 5, thereby driving the rotating plate 4 to rotate synchronously. This ensures that the cross-section of the water flow channel in the guide channel 3 can be accurately adjusted by simple push and pull operations, realizing flexible control of the flow rate.

[0019] As a preferred embodiment, in order to stably fix the rotating plate 4 at any adjustable angle, please refer to... Figure 1 and Figure 2 The outer periphery of the rotating shaft 5 is provided with at least a limiting groove 6; the device also includes a fixing plate 7 and a limiting rod 8; the fixing plate 7 is fixed to the tool body 1 and is provided with a through hole; the limiting rod 8 can be inserted and removed through the through hole of the fixing plate 7 and selectively cooperate with the limiting groove 6, thereby locking the position of the rotating shaft 5 and preventing it from rotating unexpectedly under the impact of water flow.

[0020] As another preferred embodiment, for the purpose of rapid installation and modular connection of the device, please refer to... Figure 1 and Figure 3 The device also includes a fixing mechanism 2 for mounting the tool body 1; the fixing mechanism 2 includes a fixing block 201, on which a first mounting groove 202 is provided, and the tool body 1 is detachably mounted in the first mounting groove 202; in order to realize the connection between multiple tool bodies 1, a sliding groove 203 is provided on one side of the tool body 1 and a second mounting groove 205 is provided on the other side; the fixing mechanism 2 also includes a sliding block 204, which is adapted to slide along the sliding groove 203 of the tool body 1 and engage with the second mounting groove 205 of another adjacent tool body 1 to realize the quick splicing of two tool bodies 1; in order to lock the connection, the fixing mechanism 2 further includes a screw 206 and a washer 207, the screw 206 passes through the washer 207 and is threadedly connected to the tool body 1, and abuts against the sliding block 204, thereby firmly locking the sliding block 204 and ensuring the connection stability between units.

[0021] As a further preferred embodiment, in order to optimize the transmission efficiency and smoothness of the linear motion of the sliding rod 10 to the rotational motion of the rotating shaft 5, the groove 11 on the inner wall of the sliding rod 10 is specifically a spiral groove extending along the axial direction of the sliding rod 10, and the end of the protrusion 12 slides in conjunction with the spiral groove, so that the smooth pushing and pulling action can be uniformly converted into rotational action.

[0022] Working principle: When the main body 1 of the tool is to be used, the sliding rod 10 is pulled, causing the sliding rod 10 to slide on the outer wall of the support rod 9, thereby causing the protruding rod 12 to slide in the protruding groove 11 on the inner wall of the sliding rod 10, thereby driving the rotating shaft 5 to rotate. The rotation of the rotating shaft 5 will drive the rotating plate 4 to rotate. After the rotating plate 4 rotates, the limiting rod 8 is pulled, so that the limiting rod 8 connects the limiting groove 6 on the inner wall of the rotating shaft 5 to the fixing plate 7, thereby fixing the rotating shaft 5 so that it cannot rotate. This allows the flow rate to be controlled when water passes through the inner wall of the guide channel 3, thereby adjusting the flow rate to adapt to different flood intensities, improve flood control safety, enhance operational flexibility, and cope with complex working conditions. The fixing mechanism 2 facilitates the installation of the tool body 1. The tool body 1 is installed on the inner wall of the first mounting groove 202 by the fixing block 201. After installation, the sliding block 204 passes through the inner wall of the sliding groove 203 and the inner wall of the second mounting groove 205 on the other side of the tool body 1, thereby connecting the tool body 1 to the tool body 1. Then, the screw 206 and the washer 207 fix the sliding block 204 so that it cannot move, thus achieving the effect of quick installation, fast emergency response, and convenient transportation and storage.
